Description

Technical Field

[0001] This utility model relates to a battery module processing equipment, and more particularly to a battery module water-cooled plate positioning and mounting device. Background Technology

[0002] Prismatic battery modules are a common type of new energy battery module, assembled from multiple battery cells. The combined action of these cells gives the prismatic battery module a larger capacity. The assembly process typically involves first assembling multiple cells side-by-side into a horizontally shaped battery unit, then attaching water-cooling plates to both sides of the battery unit, covering both sides of the cell; finally, assembling these battery units into a complete prismatic battery module. In existing technologies, prismatic batteries are usually placed on an assembly table, with a fixed beam positioning the ends of the battery units, and then the remaining battery units or water-cooling plates are assembled sequentially in a fixed direction. Furthermore, the water-cooling plate mounting and battery unit assembly are not performed at the same workstation. With the development of new energy technologies, there are various models of water-cooling plates and battery units, and their compatibility varies. Conventional battery module processing equipment is usually custom-designed, making it difficult to accommodate the assembly needs of various products and adapt to the development of new technologies. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a battery module water-cooled plate positioning and mounting device, characterized in that: it includes a base plate, a module positioning mechanism disposed on the base plate, and a water-cooled plate positioning mechanism disposed on the longitudinal side of the module positioning mechanism;

[0004] The module positioning mechanism includes a guide rail arranged along the length direction on the base plate, a support component that provides bottom support for the battery module, a transverse plate slidably connected to both sides of the X-axis of the guide rail, and a module clamping part provided on the transverse plate. The transverse plate is connected to the driving end of a transverse linear module and is driven by the transverse linear module to slide along the guide rail.

[0005] The water-cooled plate positioning mechanism includes a crossbeam on both sides of the module material width direction, water-cooled plate positioning grippers on both sides of the crossbeam length direction, and a pressurizing cylinder. The driving end of the pressurizing cylinder is connected to a first push block. The water-cooled plate positioning grippers position the two sides of the water-cooled plate. The first push block pushes the water-cooled plate to move along the Y-axis under the drive of the pressurizing cylinder.

[0006] Furthermore, the transverse linear module adopts a lead screw drive structure, including a first servo motor fixed on the base plate, a first transmission rod connected to the drive end of the first servo motor via a transmission wheel, and the other end of the first transmission rod being connected to the bottom of the transverse plate.

[0007] Furthermore, the end face of the module clamping part opposite to the module material is provided with a U-shaped groove to avoid the position of the water-cooled plate pipe opening.

[0008] Furthermore, the transverse plate is provided with a first lifting module arranged in the vertical direction, and the module clamping part is connected to the driving end of the first lifting module, which drives the vertical movement.

[0009] Furthermore, the support assembly includes multiple sets of support frames arranged along the length of the module, and each set of support frames has a first equal-height pad on its upper surface.

[0010] Furthermore, the support frame is connected to the guide rail via a slider, and a bearing follower is provided on the support frame.

[0011] Furthermore, a clamp is installed between the slider and the guide rail.

[0012] Furthermore, the water-cooled plate positioning gripper and the pressurizing cylinder are connected to the two side beams through support blocks, and the outer side of the water-cooled plate positioning gripper is a U-shaped groove structure for positioning the water-cooled plate pipe opening.

[0013] Furthermore, the crossbeam is provided with a compatible linear module along its extension direction, and the drive end of the compatible linear module is connected to a second lifting module arranged in the vertical direction. The support block is connected to the drive end of the second lifting module.

[0014] Furthermore, a support plate is connected to the middle of the crossbeam, and second leveling pads are installed on the inner surfaces of the support blocks on both sides of the crossbeam and the support plate in the middle of the crossbeam.

[0015] This utility model provides a battery module water-cooled plate positioning and mounting device, including a module positioning mechanism and a water-cooled plate positioning mechanism disposed on the longitudinal side of the module positioning mechanism. The module positioning mechanism fixes the position of the battery module, and the water-cooled plate positioning mechanism fixes the position of the water-cooled plate. Then, by setting a pressurizing cylinder, the water-cooled plate is driven to move towards the position of the battery module to complete the assembly of the entire battery module.

[0016] This invention differs from the existing technology that uses a reference beam to position the stacked battery module. Instead, it positions the battery module and the water-cooling plate separately. The positioning and mounting device provided by this invention has the advantages of accurate positioning, strong compatibility, and high cycle life. After the battery module is positioned, subsequent processing can be carried out directly, such as installing an insulating cover on the battery module, saving processes and improving the assembly efficiency of the battery module.

Detailed Implementation

[0027] like Figure 1 The battery module water-cooled plate positioning and mounting device shown includes a base plate 1, a module positioning mechanism 2 disposed on the base plate 1, and a water-cooled plate positioning mechanism 3 disposed on the longitudinal side of the module positioning mechanism 2. The module positioning mechanism 2 drives the battery module to a predetermined position, and the water-cooled plate positioning mechanism 3 moves from the longitudinal side toward the battery module, positions the water-cooled plate, and presses the water-cooled plate onto both longitudinal sides of the battery cell. In this embodiment, there are two sets of water-cooled plate positioning mechanisms 3 corresponding to both sides of the battery module, which assemble the water-cooled plates on both sides of the battery module respectively. Alternatively, the water-cooled plate can be placed on only one side of the water-cooled plate positioning mechanism 3 for water-cooled plate assembly of the battery module, while the water-cooled plate on the other side only provides basic support for the module material. Similarly, the module material positioned by the module positioning mechanism can be a single cell assembly unit as provided in this embodiment, or a module unit composed of multiple battery assembly units.

[0028] Define the length direction of the module material as the X-axis and the width direction as the Y-axis, such as... Figures 2 to 4 As shown, the module positioning mechanism 2 includes a guide rail 201 arranged along the X-axis on the base plate 1, a support assembly providing bottom support for the battery module, a transverse plate 202 slidably connected to both sides of the guide rail 201 along the X-axis, and a module clamping part 203 provided on the transverse plate 202. The module material is placed along the arrangement direction of the support assembly. The transverse plate 202 is connected to the driving end of a transverse linear module 204. Driven by the transverse linear module 204, it slides along the guide rail 201, so that the module clamping part 203 can move from the lateral sides of the module material to the middle, pushing the module material to the target position.

[0029] The transverse linear module 204 adopts a screw drive structure, including a first servo motor 205 fixed on the base plate 1, and a first transmission rod 206 connected to the drive end of the first servo motor 205 via a transmission wheel. The other end of the first transmission rod 206 is connected to the bottom of the transverse plate 202. In this embodiment, each of the two sets of transverse plates 202 on both sides is equipped with a set of first transmission rods 206. The ends of the two sets of first transmission rods 206 are connected by a coupling, and the same first servo motor 205 controls the transverse plates 202 on both sides to move towards or away from each other. Of course, the first servo motor 205 can be set to two sets, respectively controlling the two sets of transverse plates 202 to move along the X-axis. One set serves as the limiting end, moving first to the target position to limit the end position of the module material, while the other set serves as the free end, pushing the module material towards the limiting end.

[0030] In this embodiment, the end face of the module clamping part 203 opposite to the module material is provided with a U-shaped groove. The end face of the module clamping part 203 contacts the side of the module material, and the U-shaped groove is used to avoid the pipe connection position of the water-cooled plate. Further, the transverse plate 202 is provided with a first lifting module 207 arranged in the vertical direction. The first lifting module 207 also adopts a screw drive structure. The module clamping part 203 is connected to the drive end of the first lifting module 207 and is driven by the first lifting module 207 to move vertically, so as to perform servo adjustment of module materials of different specifications.

[0031] As shown in the figure, the support assembly includes multiple sets of support frames 208 arranged along the length of the module. Each set of support frames 208 has a first leveling pad 209 on its upper surface. When the module is placed on the support assembly, the first leveling pad 209 provides support for the module material and ensures that the module material maintains a consistent height throughout its positioning. The support frames 208 can be fixedly mounted on the base plate 1. In this embodiment, the support frames 208 are connected to the guide rail 201 via sliders, allowing the support frames 208 to move along the guide rail 201 and adjust their support position for the module material according to different product specifications. Specifically, the support frames 208 are equipped with bearing followers 210, and the position of each support frame 208 is adjusted by the cooperation of an external robotic arm and the bearing followers 210. Furthermore, a clamp 211 is installed between the slider and the guide rail 201 to fix the position of the support assembly on the guide rail 201, preventing the support assembly from moving along with the material's position adjustment.

[0032] like Figures 5 to 7 As shown, the water-cooled plate positioning mechanism 3 includes crossbeams 301 on both sides of the module material width direction, water-cooled plate positioning grippers 302 on both sides of the crossbeams 301 length direction, and pressurizing cylinders 303 for pushing the water-cooled plate to move along the Y-axis. The water-cooled plate positioning grippers 302 and pressurizing cylinders 303 are connected to the crossbeams 301 on both sides by support blocks 315. The outer side of the water-cooled plate positioning grippers 302 has a U-shaped groove structure for positioning the pipe opening position of the water-cooled plate. The driving end of the pressurizing cylinder 303 is connected to a first push block 304. The water-cooled plate is pushed along the Y-axis by the first push block 304 towards the side of the module material and is fixed on both sides of the module material width direction.

[0033] Furthermore, the crossbeam 301 is provided with a compatible linear module 305 along its extension direction. The driving end of the compatible linear module 305 is connected to a vertically arranged second lifting module 306. The support block 315 is connected to the driving end of the second lifting module 306. The compatible linear module 305 and the second lifting module 306 are used to adjust the clamping position of the water-cooled plate positioning gripper 302 for different water-cooled plate sizes. The water-cooled plate positioning gripper 302 moves along the X-axis under the control of the compatible linear module 305 to ensure that the pipe opening of the water-cooled plate is located between the U-shaped grooves of the water-cooled plate positioning gripper 302. The second lifting module 306 controls the water-cooled plate positioning gripper 302 to move in the vertical direction.

[0034] In this embodiment, the compatible linear module 305 adopts a screw drive structure. Two sets of compatible linear modules 305 on the same side are each connected to the drive end of a second servo motor 308 via a second transmission rod 307, enabling the two sets of water-cooled plate positioning grippers 302 on the same side to move synchronously and accurately position the water-cooled plate at a preset position. The second lifting module 306 adopts a belt pulley drive structure. A driven wheel 313 is connected to the support block 315 via a screw drive structure, and the driven wheel 313 is driven to rotate by a third servo motor 314.

[0035] Furthermore, a support plate 309 is connected to the middle of the crossbeam 301. The support blocks 315 on both sides of the crossbeam 301 and the inner surface of the support plate 309 in the middle of the crossbeam 301 are all equipped with second leveling pads 310. The second leveling pads 310 can provide certain support for the water-cooled plate, so that the pressure surface of the water-cooled plate is parallel to the side of the module material.

[0036] Furthermore, a second push block 311 is provided on the lateral outer side of the water-cooled plate positioning gripper 302. The second push block 311 is connected to the drive end of a set of side-pressure cylinders 312 and pushes from both sides of the water-cooled plate toward the middle so that the pipe opening of the water-cooled plate accurately enters the U-shaped groove area of ​​the water-cooled plate positioning gripper 302.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
