More unexpectedly, when the opening clamp assembly 2 drives the opening clamp follower 33 to slide along the length direction of the positioning guide rail 383, the first side clamp 321 and the second side clamp 322 move back to each other, and at the same time, the positioning clamp 37 is also away from the clamping station 31 along the length direction of the positioning guide rail 383 along with the follower seat 34. After the cell workpiece 4 is placed in the clamping station 31, the acting force acting on the opening clamp follower 33 is removed, the side clamp assembly 32 automatically clamps the cell workpiece 4 under the action of the clamping spring 36, and synchronously, the positioning clamp 37 pushes and presses the cell workpiece 4 under the action of the reset spring 39, so that the effects of three-face constraint positioning and clamping and fixing the cell workpiece 4 are achieved. In addition, by arranging the two assembly parts in opposition, the positioning of one driving module 1 in four directions is achieved, that is, the side clamping assembly 32 of each assembly part moves toward each other to perform clamping positioning and the two assembly parts move toward each other along the positioning rail 383 to perform positioning.

step1: the driver 11 of the driving module 1 is started to drive the clamping opening assembly 2 on the sliding module 12 to linearly move towards the clamping component until the clamping opening block 21 of the clamping opening assembly 2 is abutted to the clamping opening driven piece 33 of the corresponding clamping component, and the two clamping opening driven pieces 33 respectively move towards opposite directions;

step2: the opening clamp assembly 2 continues to linearly move forwards, pushes the opening clamp follower 33 to abut against the follower seat 34, drives the follower seat 34 to move along the length direction of the positioning guide rail 383, further drives the positioning clamp 37 to be far away from the clamping station 31, synchronously pulls the first driving piece 351 and the second driving piece 352 to correspondingly move along the cambered surface section of the first cam piece 323 and the cambered surface section of the second cam piece 324 respectively, and simultaneously pushes the first side clamp 321 and the second side clamp 322 to move oppositely, and at the moment, the reset spring 39 is in a compressed state and the clamping spring 36 is in a stretched state;

step3: respectively placing the two electric core workpieces 4 into corresponding clamping stations 31;

step4: the driving module 1 drives the clamping opening assembly 2 on the sliding module 12 to reset towards the position far away from the clamping component, the acting force acting on the clamping opening driven piece 33 is removed, the deformation of the clamping spring 36 is recovered, and the first side clamp 321 and the second side clamp 322 are driven to move towards each other, so that the cell workpiece 4 is clamped. When the deformation of the return spring 39 is recovered, the positioning piece and the follow-up seat 34 are pushed to move towards the cell workpiece 4 for resetting until the cell workpiece 4 is pressed and contacted, and the open clamp follower 33 is synchronously reset along with the follow-up seat 34.
