Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to an upper and lower sliding table type battery core automatic stacking device. Background Art

[0002] With the continuous development of new energy technology, new energy batteries are being used more and more widely, for example, as power batteries for new energy vehicles. In the production process of battery packs, it is necessary to first stack several battery cells, then attach diaphragms to the end faces of the battery cells for packaging to form a battery module, and finally arrange and connect multiple battery modules in a predetermined manner to form a battery pack.

[0003] Traditional battery cell stacking uses manual stacking, which has low work efficiency, requires a lot of manpower, and is prone to errors in battery cell placement. It is difficult to align the four sides of the battery cell and cannot ensure the consistency of the battery cell position, which can easily lead to deviations in subsequent processing and increase production costs.

[0004] At present, the automatic cell stacking process of the module line is to uniformly organize the stacked cells after completing the cell stacking, so that the edges of each cell are aligned, that is, each cell is first contacted with its large surface in turn and directly stacked into a module. However, such a stacking process has the problem of large equipment space occupation and high cost. The problem of low stacking efficiency will also occur if the cells are organized after stacking. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to solve the problem of low efficiency existing in the current battery cell stacking.

[0008] The present application sets an upper battery cell stacking table and a lower battery cell stacking table, and both the upper battery cell stacking table and the lower battery cell stacking table can be adjusted in the horizontal direction. Therefore, the position of the stacking table can be adjusted according to the working state of the stacking table. For example, when the lower layer is in the stacking position for stacking, the upper layer is in the material picking position for waiting for the robot to pick up the material, or when the upper layer is in the stacking position for stacking, the lower layer is in the material picking position for waiting for the robot to pick up the material. The positions of the upper and lower stacking tables are staggered and do not affect each other, thereby improving the battery cell stacking efficiency. The upper and lower double-sliding table stacking optimizes the equipment space.

[0009] As a further solution of the utility model: an upper battery cell stacking platform transferring motor is arranged on one side of the upper battery cell stacking platform, and the upper battery cell stacking platform transferring motor can drive the upper battery cell stacking platform to slide horizontally above the support frame, and the upper battery cell stacking platform slide rail which is slidably connected to the upper battery cell stacking platform is installed on the top of the support frame.

[0010] As a further solution of the utility model: a steel plate is arranged on the top of the base, and lower battery cell stacking table slide rails are installed on both sides of the top of the steel plate, and a lower battery cell stacking table transfer motor is installed on one side of the top of the steel plate, and the lower battery cell stacking table transfer motor can drive the upper battery cell stacking table to slide horizontally on the lower battery cell stacking table slide rails.

[0011] As a further solution of the utility model: support rails are installed in the horizontal direction on both sides of the top of the upper battery cell stacking platform, and a plurality of stacking plates are provided on the top of the upper battery cell stacking platform and between the two groups of support rails, and a stacking drive plate is provided at the bottom of the plurality of stacking plates;

[0012] The stacking drive plate can drive the clamping assembly thereon to move along the supporting slide rail and the stacking plate.

[0013] As a further solution of the utility model: the stacking plates are provided in a plurality of groups, and the plurality of groups of stacking plates are arranged in parallel with the supporting slide rails.

[0014] As a further solution of the utility model: two groups of supporting and limiting rods are symmetrically arranged on the top of the stacking plate.

[0015] As a further solution of the utility model: a centering bracket is installed at one end of the top of the stacking plate, a battery cell stacking end face reference is installed on the inner side of the centering bracket, and a linear motor is installed on the outer side of the centering bracket.

[0016] As a further solution of the utility model: the number of the clamping assemblies arranged on the stacking drive plate is the same as the number of the stacking plates.

[0017] As a further solution of the utility model: the clamping assembly includes a fixed bracket, wherein the fixed bracket is arranged at the bottom of the stacking plate, and extrusion plates are installed on both sides of the top of the fixed bracket, the two extrusion plates are located on the outside of the stacking plate, and a bottom limit block for connecting the material is installed on the inside of the extrusion plate, and a material centering mechanism is installed at the bottom of the bottom limit block for connecting the material.

[0018] As a further solution of the utility model: a telescopic cylinder capable of driving the bottom limit block of the material receiving and the material receiving centering mechanism to move downward is installed at the bottom of the fixed bracket.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] Firstly, the present application sets an upper battery cell stacking platform and a lower battery cell stacking platform, and both the upper battery cell stacking platform and the lower battery cell stacking platform can be adjusted in the horizontal direction, so the position of the stacking platform can be adjusted according to the working state of the stacking platform. For example, when the lower layer is in the stacking position for stacking, the upper layer is in the material taking position for waiting for the robot to take the material, or when the upper layer is in the stacking position for stacking, the lower layer is in the material taking position for waiting for the robot to take the material. The positions of the upper and lower stacking platforms are staggered and do not affect each other, thereby improving the battery cell stacking efficiency. The upper and lower double-slide stacking optimizes the equipment space, saves production costs, and improves the production line efficiency.

[0021] Secondly, the present application sets a telescopic cylinder at the bottom of the fixed plate. The telescopic cylinder can pull down the bottom limit block and the centering mechanism of the material connection that clamp the battery cell as a whole. Then, the battery cell will be pulled down as a whole each time it is stacked, which can ensure the fit between the bottom surface of the battery cell and the bottom surface reference. When stacking, the pulling mechanism pulls the battery cell down more reliably than relying on the gravity of the battery cell to ensure the flatness of the bottom surface, thereby improving the stacking effect.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , an upper and lower slide type battery cell automatic stacking device, including a base 1, an upper battery cell stacking platform 2, a lower battery cell stacking platform 3 and an upper battery cell stacking platform transfer motor 4, wherein the base 1 includes a steel plate 101 and a support frame 102, two groups of support frames 102 are symmetrically installed on both sides of the top of the steel plate 101, the upper battery cell stacking platform 2 is installed on the top of the two groups of support frames 102, the lower battery cell stacking platform 3 is installed on the top of the steel plate 101, and the upper battery cell stacking platform 2 is located above the lower battery cell stacking platform 3; it should be noted that the upper battery cell stacking platform 2 can move horizontally along the support frame 102, and the lower battery cell stacking platform 3 can move horizontally on the steel plate 101.

[0033] For ease of understanding and description, Figure 1 The directions of the two sets of support frames 102 are horizontal, and the other directions are based on this and analogy. It should be understood that this orientation setting is only for the convenience of description and understanding, and cannot be understood as a limitation of the present invention.

It should be noted here that the two extrusion plates can move toward each other, and a double-axis linear cylinder can be arranged on the fixed bracket, and the two extrusion plates are connected by connecting the two ends of the double-axis linear cylinder, so that the material connection bottom limit block 209 and the material connection centering mechanism 208 on the two extrusion plates can be driven to move toward the direction of the middle battery cell, thereby clamping the battery cell;

[0040] A telescopic cylinder 2010 is installed at the bottom of the fixed bracket, which can drive the bottom limit block 209 and the centering mechanism 208 of the material connection to move downward. The telescopic cylinder 2010 can drive the fixed bracket and the structure thereon to be pulled downward as a whole. Therefore, the battery cell will be pulled downward as a whole each time it is stacked, which can ensure the fit between the bottom surface of the battery cell and the bottom surface reference, thereby ensuring the stacking effect of the battery cell.

[0041] It should be noted that there are several groups of stacking plates 204, and the several groups of stacking plates 204 are arranged parallel to the support rails 2011.

[0043] The specific operating principles of this application are as follows:

[0044] When in use, the material taking mechanism places the first row of multiple battery cells of the module on the upper battery cell stacking table 2, with a hard limit as the stacking reference. After the placement is completed, the first row of battery cell clamping components clamp the battery cells, and the material taking mechanism takes the second row of multiple battery cells and puts them on the upper battery cell stacking table 2. After the placement is completed, the material receiving and centering mechanism 208 performs centering and limiting. When the upper driving motor 202 moves the second row of battery cells of the module to a position where it is almost in contact with but not in contact with the first row of battery cells, the telescopic cylinder 2010 lowers the second row of multiple battery cells as a whole. After the bottom surface of the battery cell is aligned with the bottom surface of the stack, the servo presses and stacks it. After completion, the servo returns to its original position, and repeats this process. After multiple modules are stacked on the upper battery cell stacking table 2, they slide out to the unloading position, and the lower battery cell stacking table 3 performs the next round of battery cell stacking in the same way. The present invention is fully automated and improves the efficiency of battery cell stacking. The upper and lower double-slide stacking optimizes the space occupied by the equipment. Each time the battery cell is stacked, the battery cell is pulled down as a whole to ensure that the bottom surface of the battery cell is aligned with the bottom surface reference, thereby ensuring the stacking effect.
