Pressing Claws for Accurate Product Placement in Picking Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product picking devices often experience interference fits between picking claws and product holes, leading to deviation of products from their intended assembly positions, which reduces assembly accuracy and efficiency.
Innovation Solution
A product picking device equipped with a pair of pressing claws that hold the product in place at the predetermined assembly position until the picking claws detach, preventing movement and ensuring accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If picking claws with protrusions are used to pick up products, then assembly automation is improved, but manufacturing precision deteriorates due to interference fit causing product deviation
Solution Approach 1:
A pressing claw is introduced as an intermediary component between the picking claw and the product. The pressing claw applies pressing force to the product's outer peripheral surface, acting as a mediator that prevents product deviation during the picking and placement process, thereby resolving the precision issue while maintaining automation
Solution Approach 2:
The pressing claw performs preliminary action by applying pressing force to the product before the picking claw releases it. This preliminary stabilizing action ensures the product is securely positioned and won't deviate when the picking claw protrusions are pulled out, preventing assembly failure
2Manufacturing precision
If pressing claws are added to hold the product, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The pressing claw and picking claw are merged into a single integrated picking device structure. Both claws work together in a coordinated manner, with the pressing claw providing stabilization and the picking claw performing the picking action, thereby improving precision without requiring a completely separate device

AI summary
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.
