Injection molding manipulator installation fixture need to pay attention to what matters

Installation of injection molding manipulator jig need to pay attention to the following matters:

First, fixture selection

Adaptive product features:

To choose the appropriate fixture according to the size, shape, weight and other factors of the injection product. For example, for small and regular shaped plastic products, such as plastic buttons, you can choose a simple pneumatic clamp, whose clamping force and opening and closing size can be well adapted to the product. For large or irregularly shaped products, such as automotive plastic interior parts, it may be necessary to customize special fixtures, such as a combination of vacuum suction cups and mechanical grippers, to ensure a stable and reliable grasp of the product.

Consider the material of the product, for products with a smooth surface, such as some high-gloss plastic parts, to choose a fixture that will not cause scratches or damage to its surface. For example, a fixture with a soft rubber pad or special coating can be selected to prevent damage to the surface quality of the product during clamping.

Matching production process:

The fixture should be adapted to the cycle of the injection molding process. If the injection cycle is short, the opening and closing speed of the fixture needs to be fast enough to ensure that the grasping and placing of the product is completed in a short time. For example, on some high-speed injection molding production lines, a fast response electric fixture is selected, which can complete the clamping action in a very short time and improve production efficiency.

Consider the structure and layout of the mold. The design of the fixture should avoid interference with the mold and be able to smoothly pick up the operation in the mold. For example, in some injection molding production with complex mold structures, it may be necessary to design a special shape of the fixture, so that it can accurately grasp the product in a narrow space, while not colliding with other parts of the mold.

Second, the installation process

Strictly follow the installation manual:

Different models and types of fixtures usually have corresponding installation manuals, which must be installed in strict accordance with the steps and requirements in the manual. The installation manual will detail the installation sequence of each component of the fixture, fastening torque and other key information. For example, for some fixture parts fixed by bolts, the installation manual will specify the specific bolt specifications and tightening torque, if the operation is not in accordance with the requirements, it may lead to the installation of the fixture is not firm, and the risk of loosening or even falling off during operation.

Pay attention to safety precautions during installation. When installing the fixture, it may be necessary to perform some high-altitude work (such as installing the fixture parts high up in the manipulator) or involve electrical connections. When carrying out these operations, it is necessary to strictly abide by the relevant safety regulations and wear the necessary safety protective equipment, such as seat belts, insulating gloves, etc., to prevent safety accidents.

Ensure installation accuracy:

The position of the fixture on the mechanical hand must be precise. Installation deviation may cause the fixture can not accurately grasp the product, affecting the production quality and efficiency. For example, when the center position of the fixture deviates too much from the center of movement of the manipulator, there will be deviation when grabbing the product, and it may even be impossible to grab the product. During installation, precision measuring tools, such as laser rangefinder, micrometer, etc., can be used to accurately measure and adjust the installation position of the fixture to ensure that its installation accuracy is within the specified tolerance range.

The connection between the fixture and the manipulator should be firm and reliable. The strength and stability of the joint are directly related to the safety and reliability of the fixture during operation. Generally, high-strength bolts, nuts and other connectors are used and tightened according to the specified tightening sequence and torque. At the same time, for some key connection parts, you can also use anti-loose gaskets, thread glue and other measures to prevent the connection parts from loosening due to vibration and other reasons during the operation of the manipulator.

Electrical connection and commissioning:

If the fixture involves an electrical control part, such as a fixture with a sensor, make sure the electrical connection is correct. A poor electrical connection can cause the sensor to not work properly and affect the function of the fixture. When connecting electrical lines, operate according to the circuit diagram to ensure that each wire is connected to the correct position. For example, the signal cable and power cable of the sensor cannot be connected inversely. Otherwise, the sensor may be damaged or cannot transmit signals normally.

After the installation is completed, the fixture should be debugged. The debugging includes the opening and closing action of the fixture and the adjustment of the clamping force. Through debugging, it is ensured that the fixture can work normally and the clamping force is moderate, which can grasp the product stably without causing damage to the product. For example, the clamping force of the fixture can be controlled by adjusting the parameters such as air pressure or current, and some test products can be used in the debugging process to carry out actual grasping tests, observe the work of the fixture, and make further adjustments and optimization as needed.

3. Inspection and maintenance after installation

Initial check:

After the installation is completed, the fixture should be comprehensively inspected. Check whether the various parts of the fixture are installed completely, and there are no missing or loose parts. For example, check whether the screws on the clamp are tightened, and whether the sensor is firmly installed.

Test whether the action of the fixture is flexible and smooth. You can manually operate the fixture to check whether its opening, closing, rotating and other actions have stuck or abnormal resistance. If a problem is found, it is necessary to find the cause and solve it in time, which may be due to excessive friction between parts due to improper installation, or insufficient lubrication.

Regular maintenance:

Make regular fixture maintenance plan, including cleaning, lubrication, fastening, etc. Regular cleaning of the fixture can prevent dust, oil and other impurities from affecting the moving parts of the fixture and ensure its normal operation. Lubrication can reduce wear between components and extend the service life of the fixture. Fastening work can prevent the fixture parts from loosening due to vibration and other reasons during the operation of the manipulator. For example, for some joint parts that move frequently, you can regularly apply an appropriate amount of lubricating oil, and for connecting bolts and other parts, check and tighten at specified intervals.

Check and replace the key parts of the fixture regularly. For example, the rubber pad, sensor and other parts of the clamp may be worn or damaged due to prolonged use, affecting the performance of the clamp. According to the actual use, the status of these parts should be checked regularly, and the damaged parts should be replaced in time to ensure the normal function of the fixture. At the same time, it is necessary to make a record of replacement parts in order to track the maintenance and service life of the fixture.

In short, the installation of the injection molding manipulator fixture needs to be comprehensively considered from the selection of the appropriate fixture, the strict specification of the installation process to the inspection and maintenance after installation, to ensure that the fixture can work normally and efficiently, and improve the quality and efficiency of injection molding production.
