Description

Technical Field

[0001] The utility model relates to the technical field of material taking and positioning, in particular to a material taking and positioning fixture. Background Art

[0002] Automation refers to the use of control devices (such as computers, logic controllers, hydraulic systems, pneumatic systems, etc.) and information technology to control machines and systems to reduce the need for manual operation. Automation technology is widely used in various industries and fields, aiming to improve production efficiency, accuracy, safety and repeatability, while reducing costs and reducing human errors. The development of automation technology continues to promote the progress of industry and society, but also brings about changes in the labor market, education and skills requirements. With the advancement of technology, automation will continue to expand into new areas and change the way we work and live.

[0003] In order to improve the accuracy of material picking, the material picking device in the current automated equipment usually adopts a secondary positioning placement table to perform secondary positioning on the material picking to ensure the accuracy of its product picking. This secondary positioning method increases the number of material picking steps for the robot arm, resulting in a slower efficiency rhythm, which in turn reduces work efficiency. At the same time, a space for secondary positioning placement needs to be reserved in the equipment, which requires the equipment to compress the space of other components or increase the overall size of the equipment, which places high requirements on the equipment.

[0013] (III) Beneficial effects

[0014] The utility model provides a material taking positioning fixture, which has the following beneficial effects:

[0015] 1. The material picking positioning fixture drives the suction nozzle on the cross connecting plate to descend by driving the cylinder to adsorb the product, and then rises, so that the air claw on the air claw mounting plate drives the cylinder to drive the product clamp to clamp the product to perform material picking positioning. The material picking device itself has a positioning function, and there is no need for a secondary positioning placement table for secondary positioning. This not only reduces the positioning and placing steps of the material picking, effectively improves the work efficiency of the material picking, while ensuring the accuracy of picking and taking, but also reduces the installation space requirements of the internal components of the equipment.

[0016] 2. The material picking positioning fixture limits the lifting and lowering of the suction nozzle by setting the guide column, effectively ensuring that the suction nozzle is adsorbed and raised into place. The mounting holes on the suction nozzle mounting plate and the fixing screws of the suction nozzle can be coordinated to adjust the installation position of the suction nozzle according to the size of the product to improve the flexibility and adaptability of the device. At the same time, the two sets of driving cylinders and suction nozzles and the two sets of air claw driving cylinders and product clamps enable the device to pick up two products at a time to further improve the material picking efficiency of the device.
