What are the requirements for the installation of single-axis injection molding manipulator?

The installation of single-axis injection molding manipulator has the following requirements:

Installation environment requirements

Space requirements: the manipulator should be installed next to the injection molding machine, and there should be enough space around it to facilitate the movement and later maintenance of the manipulator. Generally, it is required that the left and right sides and the upper part should be at least 0.5 meters away from the obstacle, and the front and rear direction should be determined according to the stroke of the manipulator and the mold opening distance of the injection molding machine to ensure that the manipulator will not collide with the injection molding machine and other equipment during operation.

Ground requirements: The installation ground should be flat and firm, which can bear the weight of the manipulator and the injection molding machine, to prevent the manipulator from running unsteadily due to uneven ground or insufficient bearing capacity, and the levelness error of the ground should be controlled within 2mm/m..

Ambient temperature and humidity: The ambient temperature should be kept between 5℃ and 40℃, and the humidity should be between 40% and 80% RH. Avoid installing in direct sunlight, damp, dusty or corrosive gas, so as not to affect the performance and service life of the manipulator.

Electrical installation requirements

Power supply requirements: according to the power and voltage requirements of the manipulator, a stable power supply is connected. Generally, a single-axis injection manipulator uses three-phase alternating current of 380V and 50Hz, and the voltage fluctuation range of the power supply should be within 10%, so as to ensure the voltage stability and prevent the electrical components of the manipulator from being damaged due to excessive voltage fluctuation.

Grounding requirements: In order to ensure safety, the manipulator must be reliably grounded, and the grounding resistance should not be greater than 4Ω. The grounding conductor should be made of copper with a cross-sectional area of not less than 4 mm, and the grounding line should be independent and not shared with the grounding wires of other equipment, so as to prevent electric shock accidents in case of electrical failure.

Wiring requirements: Electrical wiring should be neat and standard, avoid mixing with other power lines or signal lines, and prevent electromagnetic interference. Different types of cables should be distinguished by different colors, and both ends should be marked to facilitate later maintenance and repair.

Mechanical installation requirements

Mounting base: The mounting base of the manipulator should be closely connected with the ground or the fixed part of the injection molding machine, and fixed with high-strength bolts. The specifications and quantity of bolts should meet the requirements of the manipulator installation manual, and the tightening torque should be uniform, so as to ensure the firm mounting of the base and avoid vibration and displacement when the manipulator is running.

Robot body installation: install the robot body on the base to ensure the installation accuracy. The guide rail and slider of the robot should be installed smoothly and smoothly, and the clearance between moving parts should be adjusted properly. Generally, the axial clearance should be controlled between 0.05 mm and 0.1 mm, and the radial clearance should be controlled between 0.02 mm and 0.05 mm to ensure the stability and accuracy of the robot movement.

Connection with injection molding machine: the manipulator is connected with the injection molding machine through a special connection device, and the connection position should ensure the accuracy and reliability, so that the manipulator can accurately cooperate with the action of the injection molding machine to take and put the parts. For example, the position and time of the manipulator to take the parts should be accurately matched with the mold opening stroke and cycle of the injection molding machine.

Debugging requirements

No-load debugging: after the installation is completed, first carry out no-load debugging, and check whether all moving parts of the manipulator can operate normally, including the telescopic, rotating, lifting and other actions of the arm, and whether the speed and position control are accurate. At the same time, check whether all limit switches and sensors can work normally, and adjust and repair them in time if there are any problems.

Load debugging: after the no-load debugging is normal, load debugging shall be carried out, and the load weight shall be gradually increased according to the rated load of the manipulator, so as to check the operating conditions of the manipulator under load, such as whether the movement speed decreases, whether the position accuracy is affected, whether the motor and the driver are overheated, etc. If there is any abnormality, it is necessary to analyze the reasons and make corresponding adjustments, such as adjusting the driver parameters and checking the wear of mechanical transmission parts.

Linkage debugging with injection molding machine: Finally, the linkage debugging of manipulator and injection molding machine is carried out to simulate the actual production process, so that the manipulator and injection molding machine can work together, check whether the action coordination between them is tacit, and whether the time and position of picking and placing parts are accurate. If there is any problem, adjust the relevant parameters of manipulator and injection molding machine to achieve the best coordination state.
