[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] In order to solve the technical problem of how to integrate the clamping parts of the battery module and the carrier plate on a clamping device and realize the clamping of the battery module and the battery carrier at the same time, the utility model provides a battery module and a carrier plate clamping device, which can integrate the clamping parts of the battery module and the carrier plate on a clamping device and realize the clamping of the battery module and the battery carrier at the same time.

[0025] It should be noted that the battery module and carrier plate clamping device described in the present invention are used for but not limited to power battery processing, etc. For the convenience of explanation, in the present invention, only the battery module and carrier plate clamping device applied to power battery processing is used as an example for explanation, and the principles of battery module and carrier plate clamping device applied to the processing and clamping of other types of parts are essentially the same as those applied to power battery processing, and will not be elaborated here.

[0026] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a battery module and carrier clamping device in an embodiment of the utility model, wherein the battery module and carrier clamping device comprises a robot arm 1 and a clamping assembly 2. The clamping assembly 2 comprises a base 21, a battery module clamping member 22 and a battery carrier clamping member 23. The base 21 is arranged at the movable end of the robot arm 1, and the robot arm 1 drives the base 21 to be lifted and moved, so that it moves to a designated position for clamping by the clamping assembly 2; the battery module clamping member 22 is arranged at the bottom of the base 21, and is used for opening and closing the two ends of the battery module. By driving the robot arm 1, the battery module clamping member 22 is moved to the top of the battery module, and then downwardly sleeved to the two ends of the battery module, and then closed for clamping; the battery carrier clamping member 23 is arranged on one side of the base 21, and is used for opening and closing the side edge of the carrier. By driving the robot arm 1, the battery carrier clamping member 23 is flush with the side edge of the battery carrier, and then horizontally moved to the side edge of the battery carrier On, it can be clamped together; the movable end of the robot arm 1 is used for switching the moving position using the battery module clamp 22 and the battery carrier clamp 23. Specifically, for the battery module clamp 22 located at the bottom of the base 21, the robot arm 1 drives it to be suspended above the battery module, and then moves downward to perform subsequent clamping, and the battery carrier clamp 23 located on the side is moved to the side of the carrier, and then lowered to be flush with the carrier, and then moved horizontally to fit onto the side of the carrier, and then subsequent clamping can be performed. Under the above structural setting, the battery module clamp 22 and the battery carrier clamp 23 can be quickly switched, and no interference is generated during the clamping action, which can effectively achieve the integration of the battery module and carrier clamps into a clamping device, and at the same time achieve the purpose of clamping the battery module and the battery carrier.

[0027] It can be understood that the robot arm 1 can adopt the existing common six-degree-of-freedom robot arm, which has six degrees of freedom: X movement, Y movement, Z movement, X rotation, Y rotation, and Z rotation, which can achieve the effect of driving the clamping component 2 to move to the target position.

[0028] In one embodiment, in order to clamp the battery module, refer to Figure 1 and Figure 2The battery module clamping member 22 includes a battery clamping mechanism 221, and the battery clamping mechanism 221 includes a sliding drive mechanism 2211 and a battery clamping plate 2212. The sliding drive mechanism 2211 has two movable ends, and a pair of the battery clamping plates 2212 are respectively arranged on the two movable ends of the sliding drive mechanism 2211. The sliding drive mechanism 2211 is used to drive the two battery clamping plates 2212 to move relatively close to each other to form clamping, or to move away from each other to form loose clamping. In use, the two battery clamping plates 2212 are respectively located at the two ends of the battery module. When the movable end of the sliding drive mechanism 2211 moves, the two battery clamping plates 2212 are driven to move relatively close to each other, thereby forming a clamping of the two ends of the battery module. Conversely, when the movable end of the sliding drive mechanism 2211 moves, the two battery clamping plates 2212 are driven to move away from each other, thereby loosening the clamping of the battery module.

[0029] It can be understood that when there is one battery clamping mechanism 221, one battery module can be clamped at a time; when there are multiple battery clamping mechanisms 221, multiple battery modules can be clamped at a time.

[0030] Further, in order to clamp and drive the two battery clamps 2212 to open and close, please refer to Figure 2 The sliding drive mechanism 2211 includes a guide rail 2211a, a bidirectional lead screw 2211b, a stepping motor 2211c and a slider 2211d. The bidirectional lead screw 2211b is rotatably connected to the inner side of the guide rail 2211a. The bidirectional lead screw 2211b has two sections of threads in opposite directions, which are respectively threadedly connected to the two sliders 2211d. The slider 2211d is slidably connected to the inner side of the guide rail 2211a. The two sliders 2211d are respectively fixedly connected to the two battery clamps 2212. The bidirectional lead screw 2211b is driven to rotate by the stepper motor 2211c. Since the slider is threadedly connected to two opposite threads, the two sliders are caused to slide in the guide rail 2211a when the bidirectional lead screw 2211b rotates, and the sliding directions of the two sliders are opposite, driving the two battery clamps 2212 to move in opposite directions. When the stepper motor 2211c drives the two battery clamps 2212 to be relatively close to each other in the forward direction, it is a clamping action. When the stepper motor 2211c drives the two battery clamps 2212 to move away from each other in the reverse direction, it is a loosening action.

[0031] Furthermore, the battery clamp 2212 is in an L-shape.

[0032] Furthermore, an anti-slip pad is provided on the inner side of the battery clamping plate 2212 .

[0033] In one embodiment, see Figure 1In order to clamp two battery modules at the same time and be able to adaptively adjust according to the different arrangement spacings of the battery modules, the battery module clamping member 22 also includes a transverse driving mechanism 222, and the transverse driving mechanism 222 is arranged at the bottom of the base 21. There are two battery clamping mechanisms 221, one of which is installed on the base 21, and the other is installed on the active end of the transverse driving mechanism 222. The transverse driving mechanism 222 is used to drive the battery clamping mechanism 221 to move laterally to adjust the spacing between the two battery clamping mechanisms 221. The transverse driving mechanism 222 pushes one of the battery clamping mechanisms 221 to change the spacing between the two battery clamping mechanisms 221. When the spacing corresponds to the arrangement spacing of the battery modules, two battery modules can be clamped at one time. When the arrangement spacing of the battery modules changes, the spacing between the two battery clamping mechanisms 221 can be adjusted accordingly.

[0034] It is understandable that the lateral driving mechanism 222 can adopt a hydraulic push rod or a linear guide rail or other equipment that can perform reciprocating linear motion in a given direction, which is not limited here, as long as it can achieve the purpose of adjusting the distance between the two battery clamping mechanisms 221.

[0035] In one embodiment, see Figure 3 The battery carrier clamp 23 includes a carrier clamp mechanism 231, and the carrier clamp mechanism 231 includes a first telescopic mechanism 2311, a second telescopic mechanism 2312 and a carrier clamp 2313. The movable ends of the first telescopic mechanism 2311 and the second telescopic mechanism 2312 are respectively connected to one of the carrier clamps 2313, and the first telescopic mechanism 2311 and the second telescopic mechanism 2312 are used to drive the corresponding carrier clamp 2313 to move in opposite directions in the vertical direction, that is, the first telescopic mechanism 2311 pushes the carrier clamp 2313 downward to move, and the second telescopic mechanism 2312 pushes the carrier clamp 2313 upward to move, and the two carrier clamps 2313 are respectively engaged with the top and bottom of the side of the carrier to form a clamp.

[0036] Furthermore, in order to improve the stability of the carrier clamping, the number of the carrier clamping mechanisms 231 is two, and the two carrier clamping mechanisms 231 are horizontally arranged on the base 21 and symmetrically distributed to clamp one side of the carrier to improve the stability of the clamped carrier.

[0037] Furthermore, the carrier clamp 2313 is in a U-shape, and the plate surfaces of the carrier clamp 2313 are vertically opposite to each other, so that the U-shaped opening is horizontally facing the side of the carrier and can be put on the side of the carrier.

[0038] Furthermore, the first telescopic mechanism 2311 and the second telescopic mechanism 2312 are both pneumatic push rods.

[0039] It can be understood that the first telescopic mechanism 2311 and the second telescopic mechanism 2312 can also adopt hydraulic push rods or guide rail screw pairs and other devices with telescopic adjustment.

[0040] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail: when it is necessary to clamp the battery module, the robot arm 1 drives the clamping assembly 2 to move and move it to hover above the battery module, and the battery clamping mechanism 221 is located directly above the battery module, the robot arm 1 lowers the clamping assembly 2, and places the two battery clamps 2212 on the left and right sides of the two ends of the battery module, and drives the two battery clamps 2212 to be relatively close by the sliding drive mechanism 2211, so that the battery module can be clamped; when it is necessary to clamp the battery carrier, the robot arm 1 first drives the clamping assembly 2 to move to the side of the battery carrier, and horizontally aligns the U-shaped opening of the carrier clamp 2313 to one side of the battery carrier, and inserts the side of the battery carrier into the U-shaped opening of the carrier clamp 2313, and drives the carrier clamp 2313 to move in opposite directions in the vertical direction by the first telescopic mechanism 2311 and the second telescopic mechanism 2312 to clamp the battery carrier.

[0041] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
