[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other, as described above. Figure 1-6 .

[0020] This utility model provides: Reference Figure 1 , Figure 2 , Figure 3A lifting mechanism for a pouch battery magazine hopper includes a mechanism base 1 and a magazine hopper positioning component 2, a magazine hopper lifting component 3, and a cell lifting component 4 disposed on the mechanism base 1. The magazine hopper positioning component 2 is used to block and position the magazine hopper. The magazine hopper lifting component 3 is used to lift the magazine hopper, which is blocked and positioned by the magazine hopper positioning component 2, to a preset height. The cell lifting component 4 is used to lift the cell loaded in the magazine hopper, which is lifted to the preset height, to the preset height. The magazine hopper positioning component 2 includes a positioning drive device, the magazine hopper lifting component 3 includes a magazine lifting drive device, and the cell lifting component 4 includes a cell lifting drive device. In specific implementation of this utility model, this lifting mechanism for a pouch battery magazine hopper is used in conjunction with a conveyor line. The conveyor line transports the magazines loaded with battery cells forward. When a magazine reaches the station corresponding to the magazine positioning component 2, the magazine positioning component 2 blocks and positions the magazine. After being blocked and positioned, the magazine is lifted to a preset height by the magazine lifting component 3. This prevents the magazine currently in operation from blocking the normal operation of other magazines on the conveyor line, thus enabling synchronous operation of multiple magazines and improving work efficiency. Once the magazine is lifted to the preset height, the battery cell lifting component lifts the battery cells to a uniform unloading height, ensuring accuracy and efficiency and improving production efficiency.

[0021] Reference Figure 3 , Figure 4 In some specific embodiments, the magazine magazine positioning assembly 2 includes a blocking positioning cylinder 21 fixedly mounted on the mechanism base 1 and a blocking positioning block 22 mounted on the output shaft of the blocking positioning cylinder 21. The blocking positioning cylinder 21 is the positioning drive device of the magazine magazine positioning assembly 2. In specific operation, when it is necessary to block and position a magazine magazine, the blocking positioning cylinder 21 drives the blocking positioning block 22 to extend upward and uses the extended blocking limit block 22 to block and position the magazine magazine.

[0022] Specifically, in this embodiment, there are two blocking and positioning cylinders 21, which are respectively disposed on two opposite sides of the mechanism base 1. Two blocking and positioning blocks 22 disposed on the two blocking and positioning cylinders 21 are arranged opposite each other and are used to block and position the two opposite sides of the magazine cartridge that needs to be positioned. In application, the blocking and positioning cylinder 21 located at the rear end first drives the blocking and positioning block 22 located at the rear to extend and contact the magazine cartridge. When the magazine cartridge is blocked, the blocking and positioning cylinder 21 located at the front end drives the other blocking and positioning block 22 to extend and limit the two ends of the magazine cartridge. In this way, the magazine cartridge is completely blocked and limited.

[0023] In some specific embodiments, the blocking positioning cylinder 21 is a three-axis cylinder, which has the advantage of more uniform force distribution. A blocking positioning cylinder mounting seat 211 is provided on the side of the mechanism base 1, and the blocking positioning cylinder 21 is mounted on the blocking positioning cylinder mounting seat 211. The blocking positioning block 22 extends above the mechanism base 1.

[0024] Reference Figure 3 , Figure 5 In some specific embodiments, the magazine lifting assembly 3 includes a magazine tray 31 that can move up and down relative to the mechanism base 1 and a lifting cylinder 32 disposed on the mechanism base 1. The lifting cylinder 32 is a magazine lifting drive device of the magazine lifting assembly 3. The output shaft of the lifting cylinder 32 is connected to the bottom of the magazine tray 31 and is used to drive the magazine tray 31 to move up and down. Specifically, in this embodiment, a lifting guide post 33 is disposed on the mechanism base 1. The lifting guide post 33 is slidably mounted on the mechanism base 1 through a guide sleeve 331. The upper end of the lifting guide post 33 is fixedly connected to the bottom of the magazine tray 31. The lifting cylinder 32 is a thin cylinder and is installed between the mechanism base 1 and the magazine tray 31. A middle through groove 311 for cooperating with the battery cell lifting assembly 4 is opened in the middle position of the magazine tray 31. In application, after the magazine compartment is limited by the magazine compartment limiting component 2, the lifting cylinder 32 in the magazine compartment lifting component 3 drives the magazine tray 32 to lift. The magazine tray 32 is lifted to a preset height under the guidance of the lifting guide post 33 and the guide sleeve 331. This preset height is designed not to obstruct the normal operation of other magazine compartments on the conveyor line. The through groove 311 in the middle of the tray is designed to facilitate the lifting action of the components of the cell lifting component 4. In this embodiment, there are four lifting guide posts 33, which are connected to the four corners of the magazine tray 31. In some other embodiments, provided that performance requirements are met, the implementer may use other guiding devices to replace the lifting guide posts 33 in this embodiment, such as linear guides or linear bearings.

[0025] Reference Figure 2 , Figure 3 , Figure 6In some embodiments, the cell lifting assembly 4 includes a cell lifting guide device and a motor reducer module 41 fixedly disposed at the bottom of the mechanism base 1. The motor reducer module 41 is the cell lifting drive device of the cell lifting assembly 4 and includes a motor and a reducer. The cell lifting guide device is provided with a lifting rack 43 that can move up and down on the cell lifting guide device. The output shaft of the motor reducer module 41 is provided with a lifting gear 44 that meshes with the lifting rack 43. The upper end of the lifting rack 43 extends above the mechanism base 1 and is fixedly disposed with a cell top plate 45. The motor reducer module 41 can drive the lifting rack 43 to move up and down on the cell lifting guide device through the lifting gear 44 and finally lift the cell to be lifted to a preset position through the cell top plate 45 at the upper end of the lifting rack 43. In application, when it is necessary to lift the battery cell, the motor reducer module 41 drives the lifting gear 44 to rotate. The lifting gear 44 drives the lifting rack 43 to move upward on the battery cell lifting guide device. In this way, the battery cell top plate 45 located at the upper end of the lifting rack 43 lifts the battery cell in the magazine to a preset height. When performing the above operation, after each battery cell falls into the magazine, the battery cell top plate 45 lifts upward to the height corresponding to the thickness of the battery cell, ensuring that the uppermost battery cell is at the same feeding height, which helps to improve the falling efficiency and increase production efficiency.

[0026] In this embodiment, the cell lifting guide device is a linear guide rail device 42. The mechanism base 1 is provided with a through groove 11 for the lifting rack 43 to pass through. The upper part of the lifting rack 43 passes through the through groove 11 and extends to the top of the mechanism base 1.

[0027] In this embodiment, the battery cell top plate 45 is a non-metallic insulating plate. Using a non-metallic insulating plate as the battery cell top plate 45 can avoid damage to the battery cell due to static electricity or other conductive conditions, thus providing good protection for the battery cell. In addition, the battery cell top plate 45 is provided with a magnetic device for easy positioning with the magazine magazine. The magnetic device is matched with a pre-set pad inside the magazine magazine to facilitate precise position control and improve control accuracy.

[0028] In some specific embodiments, the battery cell lifting assembly 4 further includes a matching battery cell photoelectric sensor 46. The battery cell photoelectric sensor 46 is used to sense whether there are battery cells in the magazine compartment. The battery cell photoelectric sensor 46 is mounted on the mechanism base 1. In application, when the battery cell photoelectric sensor 46 senses that there are still battery cells in the magazine compartment, the battery cell lifting assembly 4 performs the lifting action normally. When the battery cell photoelectric sensor 46 senses that there are no battery cells in the magazine compartment, the battery cell lifting assembly returns to its original position, and then the magazine compartment lifting assembly 3 descends, and the magazine compartment positioning assembly resets.

[0029] In this embodiment, a lifting position sensor 471 is provided on the side of the cell lifting guide device, and a lifting position sensing plate 472 matching the lifting position sensor 471 is provided on the side of the lifting rack 43. The stroke of the lifting rack 43 is monitored by the lifting position sensor 471 and the lifting position sensing plate 472 to form a limit control.
