Description

Technical Field

[0001] This utility model relates to the field of battery cell module manufacturing equipment technology, and in particular to a battery cell module tooling. Background Technology

[0002] In related technologies, the manufacturing process of battery cell modules requires stacking multiple individual battery cells in a predetermined arrangement on a fixture to form a battery cell assembly with specific capacity and voltage characteristics. End plates are then installed on opposite sides of the assembly, and side plates on the other opposite sides, which are then welded together to form a complete battery cell module. However, in this stacking process, the cells are stacked upside down, making it impossible for operators to visually observe the actual orientation of the electrodes. This makes it difficult to determine the correct orientation of the cells, affecting stacking efficiency and product safety. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a battery cell module tooling that can improve the stacking efficiency of battery cells on the tooling and enhance product safety.

[0004] According to a first aspect embodiment of the present invention, a battery cell module tooling is used to connect the end plate and side plate of the battery cell module to the battery cell assembly, comprising:

[0005] The testing base plate has multiple cell stations, each cell station being configured to correspond to a cell in the cell group. The testing base plate also includes probes disposed at each of the cell stations, the probes being configured to electrically connect to the electrodes of the cell located at the cell station.

[0006] An end plate pressing device is used to press the end plate onto the battery cell assembly along a first direction;

[0007] A side plate pressing device is used to press the side plate onto the cell assembly along a second direction, wherein the first direction intersects the second direction;

[0008] The detection device is connected to the probes at each of the battery cell workstations and is used to detect the placement posture of the battery cell based on the electrical parameters detected by the probes.

[0009] A prompter, connected to the detection device, is used to issue a first prompt message when the detection device detects an abnormal placement of the battery cell.

[0010] The battery cell module tooling according to the embodiments of this utility model has at least the following beneficial effects:

[0011] When a battery cell is placed in an inverted position at the cell station, the cell's electrodes contact the probes. The detection device checks if the cell is placed incorrectly. If an abnormal placement is detected, an alert is issued, ensuring the cell is correctly oriented. Each cell has a corresponding cell station, ensuring that the orientation of each cell can be identified, improving production efficiency and accuracy. Furthermore, the end plate pressing device and side plate pressing device can directly press the end plates and side plates onto the cell assembly after inspection, avoiding repeated cell movement and further improving production efficiency.

[0018] According to some embodiments of the present invention, the first driving member includes a lead screw, a lead screw nut, and a movable connecting member. The lead screw is rotatably passed through the lead screw nut. The pressure sensor is disposed on the movable connecting member. The movable connecting member is disposed on the lead screw and can rotate relative to the lead screw so as to remain relatively stationary with the end plate support when the pressure sensor abuts against the end plate support.

[0019] According to some embodiments of the present invention, it further includes a first limiting part and a second limiting part; the first limiting part is connected to the end plate support member;

[0020] The second limiting part is connected to the first driving member and is configured to abut against the first limiting part to drive the end plate support member to move when the first driving member moves away from the end plate support member in the first direction, or to separate from the first limiting part when the first driving member moves closer to the end plate support member in the first direction.

[0021] According to some embodiments of the present invention, the end plate support includes:

[0022] The lower support is used to support the bottom of the end plate along a third direction;

[0023] An end plate support for supporting the end plate on one side along the first direction;

[0024] The pressing assembly includes a pressing drive and a pressing member. The pressing drive can drive the pressing member to move toward the lower support body to press against the end plate, or drive the pressing member to move in the opposite direction to move away from the end plate.

[0025] The first direction, the second direction, and the third direction intersect each other.

[0026] According to some embodiments of the present invention, the battery cell module tooling further includes a side seam welding nozzle assembly, which includes a first positioning assembly, a second positioning assembly, and a welding nozzle;

[0027] The second positioning component is connected to the first positioning component, and the welding nozzle is connected to the second positioning component.

[0056] Please refer to Figure 1 The battery cell module includes an end plate 10, a side plate 20, and a battery cell assembly 30. The end plate 10 is provided in two sets, located on opposite sides of the battery cell assembly 30 along a first direction. The side plate 20 is provided in two sets, located on opposite sides of the battery cell assembly 30 along a second direction. The first direction and the second direction intersect.

[0057] Please refer to Figures 2-8 This application provides a battery cell module tooling for connecting the end plate 10 and the side plate 20 to the battery cell assembly 30. Please refer to... Figures 2-4 The battery cell module tooling includes a testing base plate 100, an end plate pressing device 200, a side plate pressing device 300, a testing device, and an indicator 400.

[0058] Please refer to Figure 3 and Figure 4 The battery cells are stacked on the detection base plate 100. After stacking, adhesive is applied between the end plate 10 and the battery cell assembly 30, and between the side plate 20 and the battery cell assembly 30. The end plate pressing device 200 presses the end plate 10 onto the battery cell assembly 30 in a first direction and holds the pressure for a first preset time. The side plate pressing device 300 presses the side plate 20 onto the battery cell assembly 30 in a second direction and holds the pressure for a second preset time. The first preset time and the second preset time can be the same.

[0059] The testing base plate 100 has multiple cell stations, each corresponding to a cell in the cell assembly 30. The testing base plate 100 also includes probes 110 disposed at each cell station, configured to electrically connect to the electrodes of the cell at that station. For example, each cell station has two probes 110, used to connect the positive and negative electrodes of the cell, respectively.

[0060] The detection device is connected to the probes 110 at each cell station and is used to detect the placement posture of the cells based on the electrical parameters detected by the probes 110. The indicator 400 is connected to the detection device and is used to issue a first warning message when the detection device detects an abnormal cell placement. For example, an abnormal cell placement specifically refers to the cell being placed backwards, causing electrode misalignment.

[0061] In the above embodiments, when the battery cell is placed in an inverted position at the battery cell station, the electrode of the battery cell contacts the probe 110. The detection device detects whether there is an abnormal placement of the battery cell. When an abnormal placement is detected, the indicator 400 issues a first prompt message, thereby reminding the assembly personnel to adjust the placement posture of the battery cell. Each battery cell has a corresponding battery cell station, thereby ensuring that the placement posture of each battery cell can be identified, improving production efficiency and accuracy. Furthermore, the end plate pressing device 200 and the side plate pressing device 300 can directly press the end plate 10 and the side plate 20 onto the battery cell group 30 after the inspection is completed, thereby avoiding repeated movement of the battery cells and further improving production efficiency.

[0062] Please refer to Figure 3 and Figure 4 In some embodiments, the detection base plate 100 includes a base plate 120 and a first support portion 130 protruding from the base plate 120. A probe 110 is disposed on the first support portion 130. There are multiple first support portions 130 arranged in pairs, with the pairs of first support portions 130 parallel and spaced apart. Cell workstations are distributed on the pairs of first support portions 130. When a cell is placed on a cell workstation, it is supported by the pairs of first support portions 130, and the two electrodes of the cell respectively contact one probe 110 of each of the two first support portions 130. This ensures that the contact between the probe 110 and the electrode is not affected by the flatness of the base plate 120, resulting in more stable and reliable detection.

[0063] Wherein, the length extension direction of the first support portion 130 is the first direction, and the probe 110 is a boss protruding from the first support portion 130. On any first support portion 130, multiple probes 110 are spaced apart along the first direction.

[0064] The battery cell assembly 30 includes battery cells and a partition disposed between the large surfaces of adjacent battery cells. In some embodiments, the detection base plate 100 also includes a plurality of second support portions 140. The second support portions 140 are disposed on the base plate 120 and protrude upward. The second support portions 140 are located between two pairs of first support portions 130 and are used to support the partition.

[0065] Please refer to Figure 4 In some embodiments, the indicator 400 includes multiple indicator light groups, which are used to issue a prompt message, such as emitting red light, when the detection device detects an abnormal placement of the battery cell. The number of indicator light groups is not limited; for example, only one indicator light group can be set, with each battery cell station's probe 110 connected to this indicator light group. During assembly, the battery cells are placed one by one into their corresponding battery cell stations, and this single indicator light group is used to indicate the orientation of the currently placed battery cell. After a battery cell is placed into the current station, if the indicator light group emits red light, the orientation of the battery cell needs to be adjusted. Once correctly adjusted, the indicator light group emits green light to indicate correct placement, and then subsequent battery cells can be placed.

[0066] In other embodiments, indicator light groups are set up corresponding to battery cell workstations. That is, each battery cell workstation has a corresponding indicator light group. When an abnormality is detected at a certain battery cell workstation, the corresponding indicator light group lights up red to indicate the location of the abnormality.

[0067] In some embodiments, the indicator light group includes a first indicator light and a second indicator light. The first indicator light is used to emit a first indication message, such as emitting red light, when the detection device detects an abnormal cell placement. The second indicator light is used to emit a second indication message, such as emitting green light, when the detection device detects that the cell placement is normal. The color change of the indicator light group intuitively reflects the cell placement status and can avoid the situation where other abnormalities are not detected.

[0068] Please refer to Figures 5-7 In some embodiments, the end plate pressing device 200 includes two sets of end plate supports 210 and a first driving member 220. The two sets of end plate supports 210 are disposed on opposite sides of the detection base plate 100 along a first direction. The first driving member 220 is configured to drive the two sets of end plate supports 210 to move relative to each other along the first direction to drive the end plate 10 to press onto the cell assembly 30, or to move in opposite directions to separate from the end plate 10.

[0069] The number of first driving components 220 can be one set, and the two sets of end plate support components 210 are driven by one set of first driving components 220. The number of first driving components 220 can be two sets, with each set of first driving components 220 corresponding to one set of end plate support components 210.

[0070] The specific structure of the first driving component 220 is not limited; for example, it can be an electric drive assembly. Exemplarily, the first driving component 220 includes a first handwheel 224, a lead screw 221, and a lead screw nut 222. The first handwheel 224 is connected to the lead screw 221, which is rotatably mounted on the lead screw nut 222. The lead screw nut 222 is fixedly mounted. Rotation of the first handwheel 224 drives the lead screw 221 to rotate, thereby causing the lead screw 221 to move relative to the lead screw nut 222 in a first direction.

[0071] Among them, reference Figure 6 The lead screw nut 222 is fixed as follows: the battery cell module fixture also includes a fixture base plate 810 and a first bracket 820. The end plate pressing device 200 and the side plate pressing device 300 are both mounted on the fixture base plate 810. The first bracket 820 is fixed to the fixture base plate 810, and the lead screw nut 222 is mounted on the first bracket 820, thereby indirectly and fixedly connected to the fixture base plate 810.

[0072] The end plate pressing device 200 also includes two sets of first support platforms 230. The end plate support members 210 are respectively set on the corresponding first support platforms 230. The first support platforms 230 and the tooling base plate 810 are slidably connected through the slide rail assembly, so that the first driving member 220 can push the first support platform 230 and the end plate support member 210 to slide together along the first direction.

[0073] Please refer to Figures 5-6 In some embodiments, the battery cell module fixture includes a pressure sensor 510 and a pressure display 520. The pressure sensor 510 measures the pressure between the end plate 10 and the battery cell assembly 30. The pressure display 520 is connected to the pressure sensor 510 and displays the pressure value. This allows the operator to easily control the pressure between the end plate 10 and the battery cell assembly 30.

[0074] The pressure sensor 510 is disposed between the first driving member 220 and the end plate support member 210. The first driving member 220 can push the end plate support member 210 through the pressure sensor 510, thereby pushing the end plate 10, so as to indirectly and accurately obtain the pressure value between the end plate 10 and the cell assembly 30.

[0075] Please refer to Figures 6-7In some embodiments, the first driving member 220 includes a lead screw 221, a lead screw nut 222, and a movable connector 223. The lead screw 221 is rotatably mounted on the lead screw nut 222. The pressure sensor 510 is mounted on the movable connector 223, which is mounted on the lead screw 221 and can rotate relative to the lead screw 221. Thus, rotating the lead screw 221 causes the lead screw 221, the movable connector 223, and the pressure sensor 510 to move relative to the end plate support 210. When the pressure sensor 510 abuts against the end plate support 210, the lead screw 221 continues to rotate and apply pressure. The movable connector 223 and the pressure sensor 510 remain relatively stationary with respect to the end plate support 210. This avoids the pressure sensor 510 from rotating synchronously with the lead screw 221, which could affect the detection effect and damage the pressure sensor 510.

[0076] Please refer to Figure 7 For example, a bearing 225 is provided at one end of the lead screw 221. The inner ring of the bearing 225 is fixed to the lead screw 221, and the outer ring of the bearing 225 is fixed to the movable connector 223. In this way, when the lead screw 221 rotates, the movable connector 223 does not rotate with it. The movable connector 223 includes a first connecting sleeve 2231, a second connecting sleeve 2232, and a third connecting member 2233. The first connecting sleeve 2231 is connected to the second connecting sleeve 2232 and clamps the outer ring of the bearing 225 to achieve axial positioning of the two. The third connecting member 2233 is located on the side of the second connecting sleeve 2232 opposite to the first connecting sleeve 2231. The pressure sensor 510 is located on the side of the third connecting member 2233 opposite to the second connecting sleeve 2232, so as to facilitate the acquisition of the pressure value between the sensor and the end plate support 210.

[0077] It is understandable that the pressure sensor 510 needs to withstand pressure to detect the pressure value. However, when the first drive member 220 moves along the first direction and away from the cell assembly 30, it needs to drive the end plate support member 210 to move away from the cell assembly 30. At this time, since the pressure sensor 510 cannot withstand the tension, other components need to be set up to transmit the force.

[0078] In some embodiments, please refer to Figure 7 The battery cell module tooling also includes a first limiting part 610 and a second limiting part 620.

[0079] The first limiting part 610 is connected to the end plate support 210. The second limiting part 620 is connected to the first driving member 220 and is configured to abut against the first limiting part 610 when the first driving member 220 moves away from the end plate support 210 in a first direction, thereby driving the end plate support 210 to move away from the cell assembly 30; or to separate from the first limiting part 610 when the first driving member 220 moves in the opposite direction and approaches the end plate support 210. In this case, no force is transmitted between the first limiting part 610 and the second limiting part 620, so as not to affect the pressure value detected by the subsequent pressure sensor 510. It is understood that the first limiting part 610 and the second limiting part 620 at least partially overlap in the first direction.

[0080] For example, please refer to Figure 6 and Figure 7 The end plate support 210 includes a second bracket 214 that is fastened to the first support platform 230. The second bracket 214 has a cylindrical body 2141. A first limiting part 610 is a retaining ring that connects to the cylindrical body 2141 and protrudes radially inward. A second limiting part 620 is disposed inside the cylindrical body 2141 and is a convex ring that connects to the second connecting sleeve 2232 and protrudes radially outward. The cylindrical body 2141 and the retaining ring can be integrally formed, and the second connecting sleeve 2232 and the convex ring can be integrally formed.

[0081] In some embodiments, please refer to Figure 6 The end plate support 210 includes a lower support 211, an end plate support 212, and a pressing assembly 213.

[0082] The lower support 211 is used to support the bottom of the end plate 10 along a third direction, where the first direction, the second direction, and the third direction intersect each other. The end plate support 212 is used to support the end plate 10 on one side along the first direction (with...). Figure 6 Taking the end plate 10 located at the left end of the cell module as an example, the end plate support 212 supports the left side of the end plate 10. The pressing assembly 213 includes a pressing drive 2131 and a pressing member 2132. The pressing drive 2131 can drive the pressing member 2132 to move toward the lower support 211 to press against the end plate 10, or drive the pressing member 2132 to move in the opposite direction to move away from the end plate 10.

[0083] During operation, the end plate 10 is placed on the lower support 211 and abuts against the end plate support 212. The pressing drive 2131 drives the pressing component 2132 to press against the end plate 10, thereby fixing the end plate 10 to facilitate subsequent pressing of the end plate 10 onto the cell assembly 30. After subsequent welding and other processing is completed, the pressing drive 2131 drives the pressing component 2132 to move in the opposite direction away from the end plate 10, thereby facilitating the movement of the cell module.

[0084] To facilitate the positioning of the end plate 10 along the second direction, in some embodiments, the lower support 211 is provided with a protruding first positioning pin 215, and the end plate 10 has a positioning hole. When the end plate 10 is placed on the lower support 211, the first positioning pin 215 cooperates with the positioning hole to constrain the position of the end plate 10 along the second direction. There are two first positioning pins 215, spaced apart along the second direction.

[0085] Please refer to Figure 5 and Figure 6 In some embodiments, the pressing drive 2131 is a pressing elbow clamp, which drives the pressing member 2132 to press down. The pressing member 2132 includes a first pressing block 21321, a second pressing block 21322, and an elastic member 21323 disposed between the first pressing block and the second pressing block 21322. The first pressing block 21321 is connected to the pressing elbow clamp, and the second pressing block 21322 is floatingly connected to the first pressing block 21321 through the elastic member 21323. The second pressing block 21322 is used to press against the end plate 10, thereby preventing the end plate 10 from being damaged by pressure.

[0086] The first pressing block is provided with a second positioning pin 21324 protruding towards the lower support body 211, and the end plate 10 is provided with a second positioning hole that matches the second positioning pin 21324. The second positioning pin 21324 and the second positioning hole cooperate to further position the end plate 10 along the second direction.

[0087] In some embodiments, please refer to Figure 3 and Figure 4 The side plate pressing device 300 includes two sets of side plate support members 310 and a second driving member 320. The two sets of side plate support members 310 are arranged on opposite sides of the detection base plate 100 along the second direction. The second driving member 320 is configured to drive the two sets of side plate support members 310 to move relative to each other along the second direction, so as to drive the side plate 20 to press onto the cell assembly 30, or to move away from each other to separate from the side plate 20.

[0088] The number of second driving components 320 can be one set, with two sets of side plate support components 310 driven by one set of second driving components 320. The number of second driving components 320 can be two sets, with each set of second driving components 320 corresponding to one set of side plate support components 310.

[0089] The side plate pressing device 300 also includes a second support platform 330, a second driving member 320 is disposed on the second support platform 330, and a detection base plate 100 is disposed on the second support platform 330 and located between the two sets of side plate support members 310.

[0090] The specific structure of the second driving component 320 is not limited. For example, the second driving component 320 includes a second handwheel, a forward and reverse lead screw, and a second lead screw nut. There are two sets of second lead screw nuts: one set is located at the forward end of the forward and reverse lead screw and connected to a set of side plate support members 310; the other set is located at the reverse end of the forward and reverse lead screw and connected to another set of side plate support members 310. The second handwheel drives the forward and reverse lead screw to rotate, thereby causing the two sets of side plate support members 310 to move relative to each other or in opposite directions. Thus, the operator can move both sets of side plate support members 310 by operating from one side.

[0091] Please refer to Figure 8 In some embodiments, the battery cell module tooling further includes a side seam welding nozzle assembly 700, which includes a first positioning assembly 710, a second positioning assembly 720, and a welding nozzle 730. For example... Figure 8 In a typical structure shown, the side plate 20 includes a main body extending along a first direction, and bent portions connected to both ends of the main body and bent relative to the main body to overlap the end plate 10. The end plate 10 and the side plate 20 need to be fixed by welding the bent portions to the end plate 10. Based on the above structure, this embodiment can use a welding nozzle 730 to hold the end plate 10 and the side plate 20 to facilitate welding, while also dissipating heat and reducing the temperature near the weld.

[0092] Specifically, the second positioning component 720 is connected to the first positioning component 710, and the welding nozzle 730 is connected to the second positioning component 720. The first positioning component 710 is configured to abut against the side plate 20 in a second direction to achieve positioning of the welding nozzle 730 at the connection point between the end plate 10 and the side plate 20 in the second direction. After the welding nozzle 730 completes positioning in the second direction, the second positioning component 720 is configured to push the welding nozzle 730 against the connection point between the end plate 10 and the side plate 20 in a first direction. The connection point between the end plate 10 and the side plate 20 includes a portion of the end plate 10 near the side plate 20 and a portion of the side plate 20 near the end plate 10.

[0093] The number of side seam welding nozzle assemblies 700 is determined based on the number of connections between the end plate 10 and the side plate 20. Figure 2 In this case, the number of the aforementioned side seam welding nozzle assembly 700 is 4.

[0094] For example, both the first positioning component 710 and the second positioning component 720 include a positioning elbow clamp and a positioning block. In the first positioning component 710, the positioning elbow clamp can drive the positioning block to press against the side plate 20 in a second direction, and the second positioning component 720 moves along the side plate 20 in the second direction. To avoid the positioning block of the first positioning component 710 rigidly pressing against the side plate 20, the positioning block is configured as a floating structure and has an elastic structure. When the positioning block presses against the side plate 20, the elastic structure is compressed, so that the positioning block can float and achieve flexible abutment.

[0095] The second positioning component 720 also includes a slide rail assembly for guiding the movement path of the welding nozzle 730, ensuring precise positioning of the welding nozzle 730, and improving welding quality.

[0096] Please refer to Figure 2 In some embodiments, the battery cell module tooling also includes a frame 830, rollers 840, and a tooling base plate 810. The rollers 840 are mounted on the frame 830, and the end plate pressing device 200 and the side plate pressing device 300 are disposed on the tooling base plate 810, which is disposed on the frame 830. This facilitates the movement of the tooling to subsequent processes and improves turnover efficiency.

[0097] The tooling base plate 810 can be separated from the frame 830. The tooling base plate 810 is equipped with lifting rings so that the battery cell module can be replaced by lifting when it needs to be changed.
