Technical Field

[0001] The utility model relates to the field of lithium batteries, and particularly relates to a cell module stacking tooling and a stacking device. Background Art

[0002] The cell module stacking process is a part of the lithium battery processing technology. In the cell module stacking process, a number of cells need to be stacked in sequence according to requirements, and glue is applied between adjacent cells to form a cell module through the adhesion of the glue. During the stacking process, it is required that each cell be aligned. Therefore, in the cell module stacking process, it is inevitable to use tooling to align, clamp, extrude, and fix the cells.

[0003] In the prior art, a fixture is disclosed. The fixture includes two rectangular movable plates. Bolts and nuts are inserted through the corners of the two movable plates. When in use, first fix the four bolts on one of the movable plates, arrange a number of cells along the length direction of the bolts. After the number of cells reaches the requirement, install the other movable plate on the bolts and screw nuts on the bolts to apply a clamping force to the two movable plates through the nuts, so as to realize the clamping and fixing of the cells.

[0004] Since the fixture needs to be used repeatedly for many times, when using this kind of fixture, it is necessary to disassemble it frequently, and objectively, the bolts are difficult to play a role in limiting the position, and it is difficult to ensure the alignment effect. Therefore, in view of this situation, the present application provides a cell module stacking tooling and a stacking device, which simplifies the complexity of the operation while realizing the alignment and clamping of the cells. Summary of the Utility Model

[0035] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1-3 As shown, an embodiment of the utility model provides a battery cell module stacking tool, including a clamping body 10, a clamping guide arm 20 and a locking piece 30, wherein there are two clamping bodies 10. The two clamping bodies 10 are respectively arranged on the same side of the clamping guide arm 20, and the two clamping bodies 10 can slide along the length direction of the clamping guide arm 20 (the length direction of the clamping arm in this application is the end direction). The locking piece 30 is used to fix the clamping body 10 on the clamping guide arm 20 to fix the distance between the two clamping bodies 10, so as to facilitate the stacking of different numbers of battery cells.

[0037] In the present application, the clamping guide arm 20 serves as a reference, capable of positioning the battery cell to ensure alignment of the battery cells. At the same time, the clamping guide arm 20 can also limit the moving direction of the clamping body 10, enabling the clamping body 10 to provide a relatively large clamping force for the battery cell. Meanwhile, the clamping guide arm 20 is provided only on one side of the clamping body 10, and the other side of the clamping body 10 is used for loading the battery cell, without the need to frequently disassemble the battery module stacking tooling A.

[0038] Further, a central groove 21 is provided on the clamping guide arm 20, and the central groove 21 is arranged along the length direction of the clamping guide arm 20. The aforementioned locking member 30 includes a pin shaft 31, which is divided into a first end and a second end along the length direction. The first end passes through the aforementioned central groove 21 and is fixedly connected to the clamping body 10 after passing through the central groove 21. Preferably, the first end is fixedly connected to the side surface of the clamping body 10. A pressing piece 32 and a lever arm 33 are provided at the second end of the pin shaft 31. The pressing piece 32 passes through the pin shaft 31, and the pressing piece 32 is located between the clamping guide arm 20 and the lever arm 33. The lever arm 33 is rotatably arranged on the pin shaft 31. The lever arm 33 has a protruding portion 331. When the lever arm 33 is pressed, the protruding portion 331 rotates. When the protruding portion 331 abuts against the pressing piece 32, it pushes the pressing piece 32 to move towards the clamping guide arm 20 and abut against the clamping guide arm 20. A static friction force is generated between the pressing piece 32 and the clamping guide arm 20, and the relative position of the clamping body 10 and the clamping guide arm 20 can be fixed by using this static friction force.

[0039] A rotating shaft 34 is also provided at the second end of the pin shaft 31. The rotating shaft 34 is arranged along the radial direction of the pin shaft 31. The lever arm 33 is connected to the rotating shaft 34, and the lever arm 33 can rotate about the rotating shaft 34 as an axis.

[0040] In an embodiment of the present application, the rotating shaft 34 is fixedly connected to the pin shaft 31, and the lever arm 33 is rotatably connected to the rotating shaft 34.

[0041] The lever arm 33 further includes a central portion and a lever portion. The central portion is circular, and the lever portion is arranged at the edge of the central portion. When the lever portion is pressed, the central portion can rotate with the center of the circle as the rotation center. The aforementioned protruding portion 331 is arranged at the edge of the central portion, and the protruding portion 331 rotates as the central portion rotates.

[0042] Preferably, an elastic member 35 is further provided on the pin shaft 31. One end of the elastic member 35 is connected to the clamping body 10, and the other end is connected to the pressing piece 32. In this application, the elastic member 35 is a spring, and the spring is sleeved on the pin shaft 31. The spring is inserted into the central groove 21. The spring provides an elastic force for separating the pressing piece 32 and the clamping guide arm 20, that is, the spring is in a compressed state. The spring being in a compressed state can effectively reduce the static friction between the pressing piece 32 and the clamping guide arm 20, and it is convenient to adjust the distance between the clamping bodies 10 when the convex portion 331 does not contact the pressing piece 32.

[0043] Preferably, in this application, the clamping body 10 is in a U shape.

[0044] Combined with Figure 4 and 5 This application also provides a stacking device. In addition to the aforementioned battery cell module stacking tooling A, it further includes a base 40, a loading platform 50, and a pushing mechanism (not shown in the figure). Specifically, a pair of parallel slide rails 41 are provided on the upper surface of the base 40. A pair of pushing seats 42 are provided on the slide rails 41, and a clamping body 10 is provided on each pushing seat 42. A loading platform 50 is further provided on the base 40, and the loading platform 50 is located between the two slide rails 41. The pushing mechanism is used to push one of the pushing seats 42 to slide on the slide rails 41.

[0045] Preferably, at least one loading platform 50 is provided, and several loading platforms 50 are connected end to end in sequence along the length direction of the slide rails 41.

[0046] In an embodiment of this application, the pushing mechanism includes a lead screw and a motor. The output end of the motor is in transmission connection with the lead screw, and the lead screw is screwed to the pushing seat 42. Driven by the motor, the pushing seat 42 can slide along the length direction of the slide rails 41, thereby changing the distance between the two pushing seats 42.

[0047] In this application, a backing plate 70 is further provided on the pushing seat 42. The backing plate 70 is used to fix the clamping body 10, that is, the clamping body 10 is connected to the pushing seat 42 through the backing plate 70.

[0048] In this application, the clamping body 10 is in a U shape. Correspondingly, two limiting blocks 71 are provided on the backing plate 70, and the two limiting blocks 71 are clamped on the inner contour of the clamping body 10.

[0049] In this application, the limiting blocks 71 extend along the width direction of the backing plate 70. The two limiting blocks 71 are spaced apart in the height direction of the backing plate 70. The setting of the two limiting blocks 71 facilitates the clamping of the clamping body 10 and the backing plate 70, and it is convenient for the battery cell module stacking tooling A to fall off the backing plate 70 after being locked by the locking member 30.

[0050] Preferably, the thickness D of the limiting block 71 is the same as the thickness d of the clamping body 10 .

[0051] When using the present application, a carrier 50 of corresponding length is selected according to the total length of the battery cells to be stacked. The length of the carrier 50 is greater than the total length of the battery cells. The carrier 50 is placed between the two clamping bodies 10, and the position of a pushing seat 42 is adjusted by a pushing mechanism so that the two pushing seats 42 are respectively located at the two ends of the carrier 50; based on the surface of the carrier 50 and the clamping guide arm 20, the battery cells are placed in sequence along the length direction of the slide rail 41 on the surface of the carrier 50, and glue is applied between adjacent battery cells. When all the battery cells are placed, the pushing mechanism is turned on again, and one pushing seat 42 moves toward the direction of the other pushing seat 42 to clamp the battery cells. After clamping, the pulling arm 33 is rotated to make the protrusion 331 abut against the pressing sheet 32 ​​to fix the relative positions of the two clamping bodies 10 and provide continuous clamping force for the battery cell module. Then, the pushing mechanism drives the pushing seat 42 to move away from the other pushing seat 42, removes the battery cell module stacking tool A that clamps the battery cell module, and leaves it to stand until the glue is cured, thereby completing the stacking of the battery cell modules.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
