This application claims the benefit of Chinese Patent Application No. CN202311560244.0 filed on Nov. 21, 2023 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
The present disclosure relates to a product picking device, a product assembly device comprising the product picking device and a product assembly method.
In the prior art, in order to prevent dust, it is usually necessary to install an end cap on a port of the connector housing. In order to improve assembly efficiency, a robot equipped with a picking device is usually used to complete the assembly of the end cap. The picking device includes a pair of picking claws, which have protrusions suitable for insertion into the picking hole formed in the product. The protrusions of the pair of picking claws are suitable for being moved between the engagement position engaged with the inner wall surfaces of both ends of the picking hole and the release position separated from the inner wall surfaces of both ends of the picking hole.
After placing the picked-up product at the predetermined assembly position, the protrusions of the pair of picking claws are first moved to the release position, and then pulled out from the picking hole of the product. However, due to manufacturing errors, there may be interference fit between the protrusions of the picking claw and the inner wall surface of the picking hole. At this time, the product may be moved along with the protrusions of the picking claws, which can cause the product to deviate from its predetermined assembly position and even lead to product assembly failure, requiring reassembly. This will reduce the assembly accuracy and efficiency of the product.
According to an embodiment of the present disclosure, a product picking device includes a pair of picking claws adapted to pick up a product and place the picked-up product at a predetermined assembly position, and a pair of pressing claws. The pair of pressing claws are adapted to press on the product to maintain it at the predetermined assembly position. After the product is placed at the predetermined assembly position, the pair of pressing claws are adapted to hold the product at the predetermined assembly position until the pair of picking claws detach from the product.
