Briefly introduce: how to set the picking speed of five-axis injection molding manipulator?

The setting of the picking speed of the five-axis injection molding manipulator should combine the three core factors of the opening and closing rhythm of the injection molding machine, product characteristics and picking path, and follow the principle of "safety first and efficiency adaptation". The specific operation steps and key points are as follows:

Enter the speed parameter setting interface.

Enter the motion parameter module through the touch screen or operation panel of the manipulator, and select the speed setting item corresponding to the "picking process". The five-axis manipulator needs to set the sectional speeds of the transverse axis, the drawing axis, the up-and-down axis, the rotating axis and the turning axis respectively.

Set speed parameters in sections.

Fast approaching stage: During the no-load moving stage of the mechanical arm from the origin to the top of the mold, a high-speed gear (such as 70%-90% of the rated speed of the equipment) can be set to shorten the idle travel time, and it is necessary to ensure that the path is free of obstacles.

Part picking operation section: when the mechanical arm enters the mold cavity to grab the product, it needs to move slowly at a low speed (10%-30% of the rated speed) to avoid colliding with the mold and damaging the product; If the product is thin-walled and fragile, the speed needs to be further reduced.

Exit from the mold section: in the stage of leaving the mold cavity after grabbing the product, exit from the mold area at a low speed, and switch to high-speed movement after completely leaving the mold to balance efficiency and safety.

Rotating and transferring loading section: The rotating and overturning speed of five axes should match the product center of gravity to prevent the product from falling off. It is recommended to set the medium and low speed for heavy products, and the speed can be increased appropriately for light parts.

Matching the linkage rhythm of injection molding machine

The picking speed should be linked with the injection molding machine's mold opening completion signal and ejector pin action. By setting the waiting time or signal trigger conditions, it is ensured that the manipulator will take the part after the mold is completely opened and the ejector pin ejects the product, so as to avoid interference caused by too fast speed.

Debugging optimization and saving parameters

First, test run at low speed, observe the stability of the whole process of picking, and check whether there is jamming, jitter or product shaking; Step by step speed up to the best efficiency point, and after confirming that there is no potential safety hazard, save the parameters and name the picking program of the corresponding product for subsequent call.

Key considerations

The speed setting shall not exceed the maximum speed under the rated load of the equipment to avoid motor overload or mechanical structure wear.

The speed parameters of products with different materials and weights need to be set separately and cannot be used universally.

Regularly adjust the speed according to the operating state of the manipulator (such as rail lubrication and motor load) to maintain the best operating efficiency.
