Technical Field
[0001] This utility model relates to the field of battery cell manufacturing technology, specifically to a battery cell adjustment device and a battery cell assembly system. Background Technology
[0002] Currently, in the assembly production equipment of square-shell battery cells in the industry, the functions of clamping and positioning the battery cell, rotating the battery cell, cutting off the linear position, and changing the pitch of the battery cell center are often separate, or one or any two of them are integrated into one. At the same time, most of the rotating mechanisms use rotary cylinders to achieve rotation at a specific angle. The structural rigidity of such mechanisms is generally not good, and the cylinder is easily damaged. Therefore, in equipment with more integrated automation requirements, general mechanisms cannot meet the requirements.
[0003] Currently, the combination of cell clamping and positioning functions, cell attitude rotation functions, linear position cutting functions, and dual-cell center distance changing functions, or even a single functional mechanism, generally suffers from several pain points:
[0004] Firstly, in order to meet the requirements of automated production, multiple single-function modules need to be stacked, which occupies a lot of equipment space;
[0005] Secondly, the independent and sequential operation of multiple functional modules consumes a significant amount of production time, becoming a bottleneck for increasing equipment capacity.
[0006] Third, while one or two functional modules can sometimes be combined to meet production needs, the integration is not high and the cost remains high. Utility Model Content
[0007] The technical problem to be solved by this utility model is: how to provide a multifunctional and highly integrated battery cell adjustment device.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] A battery cell adjustment device includes a rotating cutting platform, a rotating platform on the top of the rotating cutting platform, clamping and positioning fixtures on both sides of the rotating platform, and a variable-pitch transplanting cylinder assembly between the two sets of clamping and positioning fixtures that can adjust the distance between them.
[0010] The bottom of the rotating cutting platform is equipped with a transport and transplanting module that can drive its movement, and the bottom of the rotating cutting platform is equipped with a drive component that can drive the rotating platform to rotate.
[0011] This application achieves the clamping of battery cells and the adjustment of the distance between the two battery cells by setting up a rotating cutting platform and installing clamping and positioning fixtures and variable-pitch transfer cylinder components on the rotating cutting platform. At the same time, a transport and transfer module and a drive component are set at the bottom of the rotating cutting platform, which can realize the linear cutting (i.e., linear movement) and attitude rotation of the battery cells. Therefore, this application integrates four functions into one mechanism: clamping and positioning battery cells, rotating battery cells, linear cutting of battery cells, and variable-pitch distance between the two battery cells, which greatly simplifies the original mechanism.
[0012] As a further embodiment of this utility model: the variable pitch transplanting cylinder assembly includes two sets of fixture variable pitch cylinders mounted on the fixture rotation platform, and the output ends of the two sets of fixture variable pitch cylinders are respectively connected to the clamping and positioning fixtures on both sides.
[0013] As a further embodiment of this utility model: the rotating platform is provided with variable pitch guide rails below the two sets of clamping and positioning fixtures, and the two sets of clamping and positioning fixtures are slidably connected to the corresponding variable pitch guide rails.
[0014] As a further embodiment of this utility model: the drive assembly includes a rotary drive servo motor located at the bottom of the rotary separation integrated platform, the output end of the rotary drive servo motor is connected to a reducer, and the reducer passes through the rotary separation integrated platform and is connected to the rotary platform.
[0015] As a further embodiment of this utility model: the transport and transplanting module includes a cutting and transplanting module disposed at the bottom of the rotating cutting platform, and the cutting and transplanting module can drive the rotating cutting platform to move along the cutting and transplanting module.

[0018] As a further embodiment of this utility model: the short side positioning component includes a short side positioning block and a short side cylinder mounted on the base plate of the fixture, wherein the output end of the short side cylinder is connected to the short side positioning block.
[0019] As a further embodiment of this utility model: the long side positioning component includes a long side positioning block and a long side cylinder mounted on the base plate of the fixture, wherein the output end of the long side cylinder is connected to the long side positioning block.
[0020] This utility model also discloses a battery cell assembly system, including the aforementioned battery cell adjustment device.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] This application achieves the clamping of battery cells and the adjustment of the spacing between two battery cells by setting up a rotating cutting platform and setting up a clamping and positioning fixture and a variable pitch transfer cylinder assembly on the rotating cutting platform.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0040] Example 1
[0041] Reference Figure 1 and Figure 2 A battery cell adjustment device includes a cutting and transplanting module 2, a rotating cutting platform 3, a clamping and positioning fixture 4, a variable-pitch transplanting cylinder assembly 6, a transplanting guide rail 7, a rotating interference ring 8, and a cable chain assembly 9. The transplanting guide rail 7 and the cutting and transplanting module 2 are installed below the rotating cutting platform 3, the clamping and positioning fixture 4 and the variable-pitch transplanting cylinder assembly 6 are installed above the rotating cutting platform 3, and the cable chain assembly 9 is connected to the rotating cutting platform 3. When the rotating cutting platform 3 performs linear cutting (i.e., linear transplanting), it plays a certain limiting role.
[0042] Reference Figure 2 The cutting and transplanting module 2 is installed on one side of the bottom of the rotating cutting platform 3 and is arranged parallel to the transplanting guide rail 7. The cutting and transplanting module 2 is used to drive the rotating cutting platform 3 to move linearly. A linear module or a ball screw can be selected. This application does not limit the specific equipment to be selected.
[0043] Reference Figure 3 , Figure 4 and Figure 5The top of the rotary cutting platform 3 is equipped with a rotating platform. The top two ends of the rotating platform are respectively detachably mounted with clamping and positioning fixtures 4 by bolts or pins. The bottom of the rotary cutting platform 3 is equipped with a rotary drive servo motor 32. The output end of the rotary drive servo motor 32 is connected to a reducer 31. The output end of the reducer 31 passes through the rotary cutting platform 3 and is connected to the rotating platform. Therefore, the rotary drive servo motor 32 and the reducer 31 can drive the rotating platform to rotate, thereby driving the clamping and positioning fixture 4 and the workpiece (in this application, the battery cell) on it to rotate, so as to ensure that the workpiece (in this application, the battery cell) meets the requirements of the next process.
[0044] Since the cutting and transplanting module 2 and the transplanting guide rail 7 are located below the rotating cutting platform 3, the cutting and transplanting module 2 can drive the rotating cutting platform 3 to move in a straight line along its direction. At the same time, the other side of the bottom of the rotating cutting platform 3 can slide along the transplanting guide rail 7, thereby ensuring the accuracy of the rotating cutting platform 3 when it moves.
[0045] Reference Figure 3 and Figure 4 A variable-pitch transfer cylinder assembly 6 is also provided at the top of the rotating platform and between the two sets of clamping and positioning fixtures 4. The distance between the two sets of clamping and positioning fixtures 4 can be adjusted by the variable-pitch transfer cylinder assembly 6, thereby realizing variable-pitch adjustment to ensure that the workpiece (in this application, the battery cell) adapts to the requirements of the next process.
[0046] Specifically, the variable-pitch transfer cylinder assembly 6 includes a fixture variable-pitch cylinder 1 61, a variable-pitch guide rail 1 62, a fixture variable-pitch cylinder 2 63, and a variable-pitch guide rail 2 64. The fixture variable-pitch cylinder 1 61 and the fixture variable-pitch cylinder 2 63 are arranged in parallel. The output end of the fixture variable-pitch cylinder 1 61 is connected to one of the clamping and positioning fixtures 4, while the output end of the fixture variable-pitch cylinder 2 63 is connected to the other clamping and positioning fixture 4. The fixture variable-pitch cylinder 1 61 and the fixture variable-pitch cylinder 2 63 can drive the corresponding clamping and positioning fixtures 4 to move, thereby adjusting the distance between them and realizing the variable-pitch adjustment of the workpiece on them.
[0047] It should be noted that variable pitch guide rail 1 62 and variable pitch guide rail 2 64 are respectively provided at the top of the rotating platform and at the bottom of the two sets of clamping and positioning fixtures 4. Variable pitch guide rail 1 62, variable pitch guide rail 2 64, fixture variable pitch cylinder 1 61 and fixture variable pitch cylinder 2 63 are all arranged in parallel. When the two sets of clamping and positioning fixtures 4 are moving, they can move along the corresponding variable pitch guide rail. The setting of variable pitch guide rail can play a certain limiting role for clamping and positioning fixtures 4.
[0048] Reference Figure 6 , Figure 7 and Figure 8 The clamping and positioning fixture 4 includes a fixture base plate 41, a long side positioning block 42, a short side cylinder 43, a short side positioning block 44, and a long side cylinder 45. The fixture base plate 41 has several mounting holes for detachable connection with the rotating platform. The long side positioning blocks 42 are symmetrically arranged on both sides of the top long side of the fixture base plate 41. One side of the long side positioning block 42 is slidable and connected to the long side cylinder 45 on the fixture base plate 41. Therefore, the long side cylinder 45 can drive the long side positioning block 42 on one side to move. When positioning the workpiece later, the position of the long side positioning block 42 can be adjusted according to the size of the workpiece.
[0049] Short side positioning blocks 44 are symmetrically arranged on both sides of the top short side of the fixture base plate 41. One of the short side positioning blocks 44 is slidable and connected to the short side cylinder 43 on the fixture base plate 41. Therefore, the short side cylinder 43 can drive the short side positioning block 44 on the middle side to move. When positioning the workpiece later, the position of the short side positioning block 44 can be adjusted according to the size of the workpiece.
[0050] Example 2
[0051] Reference Figure 1 A battery cell assembly system includes the battery cell adjustment device described in Embodiment 1. The battery cell 10 is transferred from the previous process 1 to two sets of clamping and positioning fixtures 4 for feeding. Then, under the control of the battery cell adjustment device of this application, the battery cell is clamped and positioned, the battery cell attitude is rotated, the battery cell is cut in a straight line, and the center distance between the two battery cells is changed. After adjusting it as needed, it is transferred to the next process 5.
[0052] The specific operating principle of this application is as follows:
[0053] The dual-cell mechanical gripper picks up two cells from the previous process 1 station and transfers them to the loading station. Then, it places the cells on two sets of clamping and positioning fixtures 4. At this time, the two positioning fixtures position the cells 10 along their long and short sides. After positioning and clamping, the cells are transferred to the unloading position for unloading under the action of the cutting and transferring module 2.
[0054] During the transplanting and cutting process, the rotary cutting platform 3, under the action of the rotary drive servo motor 32, completes the 90° rotation of the clamping and positioning fixture 4 and the battery cell 10. At the same time, during the rotation and transplanting process, under the action of the variable-pitch transplanting cylinder assembly 6, the center distance of the two clamping and positioning fixtures 4 is changed, that is, the center distance of the battery cell 10 is changed to meet the requirements of the next process for the center distance of the battery cell 10. After the rotary cutting platform 3 reaches the unloading station (not shown in the text), the short side cylinder 43 and the long side cylinder 45 of the two clamping and positioning fixtures 4 are released, the battery cell is unlocked, and under the action of the dual robotic arms, it is transplanted to the next process station for processing.
[0055] Introduction to the rotating and cutting integral platform 3: The battery cell 10 is placed on two clamping and positioning fixtures 4. The long side cylinder 45 of the fixture pushes the battery cell 10 to the side for positioning. After the long side positioning is completed, the long side cylinder 45 is released. At this time, the short side cylinder 43 pushes the battery cell 10 to the side for positioning. After positioning and clamping, it continues to be held. At this time, the long side cylinder 45 clamps the side of the battery cell again. At this time, the fixture positions the battery cell on the long and short sides.
[0056] After the long and short sides are positioned, during the transfer and separation process, the rotating separation platform 3, under the action of the rotating drive servo motor 32, completes the 90° rotation of the clamping fixture and the battery cell. At the same time, during the rotation and transfer process, under the action of the variable pitch transfer cylinder assembly 6, and under the action of the fixture variable pitch cylinder 1 61 and fixture variable pitch cylinder 2 63, the pitch of the two fixtures is changed, that is, the pitch of the battery cell center distance is changed to meet the requirements of the next process for the battery cell center distance. The rotation of the battery cell and the pitch change of the center distance are both completed during the transfer process of the rotating separation platform 3, which greatly improves the cycle efficiency of this mechanism and better meets the needs of high-speed production lines.
[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
