Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0046] Mounting base plate 1, the lower of mounting base plate 1 is provided with two symmetrical extrusion mechanisms 2, and extrusion mechanism 2 is used to extrude battery module;

[0047] Transmission mechanism 3 is set on mounting base plate 1 and is connected with two sides extrusion mechanism 2;

[0048] Driving mechanism 4 is set on the upper of mounting base plate 1, for driving two sides extrusion mechanism 2 to be close to each other or away from each other under the cooperation of transmission mechanism 3.

[0049] When the application is used, the battery cell module is first fixed by the module tooling plate, and then conveyed to the front of the working station by the roller conveying line. At this time, the range extrusion clamp is in an open state. The range extrusion clamp is lowered to the two sides of the module tooling plate of the battery cell module by the lifting mechanism of the working station. Then the driving mechanism 4 drives the transmission mechanism 3 to move, and at this time the transmission mechanism 3 drives the two sides of the extrusion mechanism 2 to move towards each other, that is, the extrusion mechanism 2 moves towards the middle battery cell module, and finally the two sides of the extrusion mechanism 2 extrude the two sides of the battery cell module. At this time, the stroke of the extrusion mechanism 2 is the stroke of the transmission mechanism 3 plus the stroke of the driving mechanism 4, which has the effect of range extension, so that the extrusion mechanism 2 can extrude the longer battery cell module, greatly avoiding the large space occupation caused by the use of a longer electric cylinder or two electric cylinders. The extrusion clamp of the application can occupy a small space through the cooperation of the driving mechanism 4 and the transmission mechanism 3, which is more conducive to the layout of the equipment, thereby not affecting the space layout of the whole production line body, and at the same time saves a lot of cost, effectively improves the production efficiency, and can be widely used.

[0050] In this embodiment, preferably, please refer to Figures 1-4 and Figures 7-9 The transmission mechanism 3 comprises:

[0051] The gear assembly 31 is arranged above the mounting base plate 1.

[0052] The rack assembly 32 is provided with two rack assemblies 32 and is slidably arranged on the mounting base plate 1. The two rack assemblies 32 are respectively located on the two sides of the gear assembly 31.

[0053] One side of the rack assembly 32 is driven by the driving mechanism 4 to move horizontally. The rack assembly 32 then drives the other side of the rack assembly 32 to move through the gear assembly 31, so that the two sides of the rack assembly 32 can move synchronously and in opposite directions. The two sides of the rack assembly 32 drive the two extrusion mechanisms 2 to move, and the two extrusion mechanisms 2 move towards each other or away from each other. Moving towards each other means clamping and extruding, and moving away from each other means opening.

[0054] In this embodiment, preferably, please refer to Figures 2-4 and Figure 7 Two through holes 5 are formed in the mounting base plate 1. The rack assembly 32 comprises:

[0055] The guide rail piece 321 is arranged on the mounting base plate 1.

[0056] The adapter plate 322 is slidably arranged on the guide rail piece 321.

[0057] The rack plate 323 is connected with the adapter plate 322 on one side, and is provided with a connecting plate 324 on the other side. The lower end of the connecting plate 324 penetrates through the through hole 5 and is connected with the extrusion mechanism 2.

[0058] When the driving mechanism 4 is started, the connecting plate 324 of one side of the rack plate 323 is moved, the connecting plate 324 drives the adapter plate 322 and the guide rail 321 to slide, thereby driving the rack plate 323 on this side to move, and then the gear assembly 31 drives the rack plate 323 and the connecting plate 324 on the other side to move, so that the connecting plates 324 on both sides drive the extrusion mechanisms 2 to move, respectively.

[0059] In the embodiment, preferably, referring to Figures 2-4 , the guide rail 321 comprises a guide rail 3211 arranged on the mounting base plate 1, and a sliding block 3212 connected with the adapter plate 322 is arranged on the guide rail 3211. When the rack plate 323 and the adapter plate 322 move, the adapter plate 322 moves along the guide rail 3211 through the sliding block 3212, which can improve the stability and smoothness of the movement of the adapter plate 322, the rack plate 323 and the connecting plate 324, and has high practicability.

[0067] When the servo motor 41 and the electric cylinder 42 are started, the output end of the electric cylinder 42 drives the connecting block 43 to move back and forth, that is, drives the connecting plate 324 and the rack plate 323 connected with the connecting block 43 to move back and forth. Since the extrusion mechanism 2 is connected with the rack assembly 32 through the guide rail piece 321, the extrusion mechanism 2 moves with the rack plate 323, and if the stroke of the electric cylinder 42 is N, the stroke of the rack plate 323 of the rack assembly 32 is also N, so the stroke of the extrusion mechanism 2 is the sum of the strokes of the two rack plates 323, that is, the stroke of the extrusion mechanism 2 is 2N, that is, the extrusion mechanism 2 achieves the effect of increasing the stroke, so the distance between the two extrusion mechanisms 2 can be used to extrude the battery cell module with a longer stroke of the electric cylinder 42, that is, the extrusion clamp of the application achieves the effect of increasing the stroke, occupies small space, is more conducive to the layout of the equipment, saves more cost, and can be widely used.
