Technical Field

[0001] The utility model relates to the field of pallets for lithium battery production, in particular to pallets for lithium battery production. Background Art

[0002] At present, in the power battery module production line, the pallet carries the battery module and moves back and forth between various stations through the assembly line, from loading to unloading, and finally completing the finished product. During the movement of the pallet, the battery module is clamped by the clamping mechanism installed on the pallet to prevent the position of the battery module from moving and affecting the welding effect. The traditional pallet clamping mechanism uses a cylinder and a linear drive motor to achieve clamping, but during the operation of the pallet, vibrations will occur, which will cause the position of the battery module to move, thus affecting the subsequent precise welding effect. Utility Model Content

The clamping device clamps a battery module located on the pallet main body through a transmission gear. The transmission gear is located inside the pallet main body. The transmission gear is locked by a telescopic ratchet inside the pallet main body. When the telescopic ratchet contracts, the transmission gear is unlocked.

[0005] Furthermore, the clamping device includes four rotating clamping devices located on the pallet body, including a rotating column and a clamping column. The clamping column is fixedly connected to the rotating column through a connecting plate. The lower end of the rotating column is fixed to the pallet body through a bearing, so that the rotating column drives the clamping column to rotate, thereby realizing multi-directional clamping.

[0006] Furthermore, an auxiliary gear is fixedly sleeved on the rotating column, and the auxiliary gear is meshed with the transmission gear.

[0007] Furthermore, the transmission gear realizes transmission through a transmission motor fixed at the lower end of the tray body.

[0008] Furthermore, the telescopic pawl is hinged in the tray body through a pin shaft, and the telescopic pawl is engaged with the ratchet teeth arranged on the transmission gear. The telescopic pawl is an inclined telescopic rod, and the telescopic rod is telescoped by an electromagnet block and a compression spring installed inside the telescopic rod.

[0009] Furthermore, a limit block is provided on the telescopic pawl, and a limit arc corresponding to the limit block is provided on the pin shaft to control the rotation angle of the telescopic pawl.

[0010] To sum up, the beneficial effects of the present application are as follows: the device of the present application utilizes a transmission gear to drive a clamping device to clamp a battery module, and at the same time a retractable ratchet is arranged on the transmission gear to prevent the rotation of the transmission gear from affecting the clamping force of the clamping device; when the retractable ratchet contracts, the rotation of the transmission gear realizes the unclamping of the battery module.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Pallets for lithium battery production, such as Figure 1 and Figure 2As shown, a transmission gear 3 is provided inside the pallet body 1, and the transmission gear 3 is meshed with the auxiliary gear 6 on the clamping device 2, and the clamping device 2 is composed of four rotating clamping devices 5, and the rotating clamping device 5 is connected to the pallet body 1 through a vertically placed rotating column 51, and the lower end of the rotating column 51 is fixed on the pallet body 1 through a bearing, and the vertically placed clamping column 52 is fixedly connected to the rotating column 51 through a connecting plate 53, and the lower end surface of the clamping column 52 is slidably connected to the upper end surface of the pallet body 1, so the rotation of the transmission gear 3 can drive the rotating clamping device 5 to rotate on the pallet body 1, and then realize the clamping of the clamping column 52;

[0021] like Figure 2 and Figure 3 As shown, the rotation of the transmission gear 3 is realized by the transmission motor 7 fixed to the lower end of the tray body 1, and a ratchet tooth 31 is provided on the outer end surface of the lower end of the gear shaft on the transmission gear 3, and the gear tooth 31 is engaged with the telescopic pawl 4, and the telescopic pawl 4 is an inclined telescopic rod, and one end of the telescopic pawl 4 is hinged in the tray body 1 through a pin 8, and the left and right ends of the telescopic pawl 4 are provided with a limit block 41, and a limit arc 81 is provided on the pin 8, the limit arc 81 can be fixed on the pin 8, but it is necessary to leave space for the telescopic pawl 4 to rotate, and the limit arc 81 can also be fixed on the tray body 1, but it is necessary to limit the rotation angle of the telescopic pawl 4.

[0022] The telescopic pawl 4 is also a telescopic rod, including a telescopic rod A and a telescopic rod B. Both the telescopic rod A and the telescopic rod B are block-shaped. The telescopic rod A can be inserted into the telescopic rod B, and the telescopic rod A is trapezoidal in shape. An electromagnet block is provided on the inner end surface of the telescopic rod B, and the telescopic rod A and the telescopic rod B are fixedly connected by a compression spring. A permanent magnet block is provided on the end surface of the telescopic rod A corresponding to the electromagnet block. When the electromagnet block has electromagnetic force, the telescopic rod A and the telescopic rod B are shortened by the principle of opposites attracting each other with the permanent magnet block. When the electromagnet block has no magnetic force, the telescopic rod A and the telescopic rod B are extended by the compression spring.

[0023] When in use, the telescopic pawl 4 is in an extended state; then the battery module is placed on the upper end surface of the tray body 1, and then the transmission motor 7 is started, so that the transmission gear 3 rotates counterclockwise, which will drive the auxiliary gear 6 to rotate, so that the rotating column 51 on the rotating clamping device 5 rotates, and then the four clamping columns 52 on the clamping tensioner 2 are all rotated toward the position of the battery module, so as to clamp the battery module;

[0024] When the transmission gear 3 rotates, the ratchet teeth 31 will also rotate. Since the telescopic pawl 4 can rotate on the pin 8, according to the characteristics of the ratchet, the two meshing ratchets can only rotate in one direction, so the telescopic pawl 4 can rotate clockwise, and the rotation of the transmission gear 3 will not be restricted at this time. When the transmission gear 3 rotates to clamp the battery module, the telescopic pawl 4 will abut against the gap of the ratchet teeth 31. At this time, when the battery module is displaced by vibration, it will be restricted by the telescopic pawl 4, thereby preventing the rotation of the transmission gear 3, and then restricting the positioning of the battery module clamping transmission device;

[0025] When the battery module needs to be loosened, it is only necessary to start the electromagnet block in the telescopic pawl 4 to shrink the telescopic pawl 4 so that the ratchet teeth 31 and the telescopic pawl 4 are not in a meshing state. At this time, the transmission motor 7 is started in reverse to make the transmission gear 3 rotate in the reverse direction. At this time, the clamping device 2 will loosen the battery module.

[0026] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
