Grabbing mechanism distance adjusting device and logistics conveying line

Abstract

The invention discloses a grabbing mechanism distance adjusting device and a logistics conveying line, relates to the field of material conveying, and aims to accurately adjust the distance between grabbing mechanisms. The grabbing mechanism distance adjusting device comprises a supporting base, a driving piece, at least two distance changing transmission parts and at least two connecting pieces. The supporting seat is configured to provide support; the driving piece is rotatably mounted on the supporting seat; and one end of each variable-pitch transmission part is rotationally connected with the driving part. Each connecting piece can be mounted on the supporting seat in a linear moving manner; the connecting pieces are in one-to-one correspondence with the variable-pitch transmission parts, and the connecting pieces are rotatably connected to the other ends of the variable-pitch transmission parts. According to the technical scheme, precise control over the distance between the connecting pieces is achieved; the connecting pieces are used for installing the grabbing mechanisms, and therefore the distance between the grabbing mechanisms can be adjusted.

Description

technical field [0001] The invention relates to the field of material transportation, in particular to a device for adjusting the distance between grasping mechanisms and a logistics conveying line. Background technique [0002] The new energy industry is booming, and the lithium battery technology is relatively mature and has a good development prospect. In the production process of lithium battery cells, the handle of lithium battery cells is the most important transfer carrier in a fully automated production line, and its importance is self-evident. [0003] In order to meet the high-energy and high-efficiency requirements of the fully automatic lithium battery production line, the grippers of lithium battery cells are mostly in the form of one tool with multiple grips, that is, one device is used to grab multiple cells at the same time. In the process of lithium battery cell circulation, due to the needs of different process stations, the spacing of different cells on t...

AI Technical Summary

Problems solved by technology

The electric drive adopts a linear motion structure in the form of a motor driving a lead screw, etc. The control is relatively complicated, and the control line of the motor drive needs to be transferred to the front end of the gripper through the mechanical arm, and the wiring is laborious

The pneumatic drive is a scissor fork structure or a multi-gap tie rod structure. When the scissor fork structure is multi-stage variable distance, due to the gap and deformation, the stability of the components at both ends is poor and the rigidity is insufficient.

The movement of the variable distance process of the multi-gap tie rod structure cell is uneven, and it cannot move symmetrically with the center of the gripper

[0005] The inventors have found that there are at least the following problems in the prior art: currently there is no mechanism that can accurately adjust the distance between the clamps
