Therefore, during the production process of the battery, carrier sheets are needed to connect the batteries. In order to enable the individual batteries to be tightly connected, capping is performed on the upper and lower layers of the batteries, forming as Figure 7 shown.

[0003] When performing capping on the carrier sheet of the lithium battery, it is necessary to arrange the individual batteries in an orderly manner. At this time, it is mostly manually operated, which is very time-consuming and laborious.

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-6 , a capping device for a lithium battery production carrier sheet, including a bottom cover conveying mechanism 1. Above the bottom cover conveying mechanism 1, a battery grouping mechanism 2 is provided. Above the bottom cover conveying mechanism 1, an upper cover conveying mechanism 3 is also installed. Above the upper cover conveying mechanism 3, a capping mechanism 4 is installed. The bottom cover conveying mechanism 1 is used to convey the bottom cover, convey the bottom cover to the lower part of the battery grouping mechanism 2 to load the battery, and after the battery is loaded, it is conveyed to the inside of the capping mechanism 4 for capping and pressurizing the top cover;

[0032] The battery grouping mechanism 2 includes a fixedly installed blanking slide plate 201. The blanking slide plate 201 is connected to a resonance disk for feeding. At the end of the blanking slide plate 201, a baffle 203 is provided to block the battery. And equidistant battery sorting ports 202 are opened at the lower bottom of the blanking slide plate 201. A partition plate 204 is also installed inside the blanking slide plate 201. The partition plate 204 equally divides the internal space of the blanking slide plate 201;

[0033] A bottom support plate 205 is fixedly connected below the battery sorting port 202. A battery guiding part 206 is installed inside the bottom support plate 205. A telescopic current-limiting plate 207 is installed on the side of the battery guiding part 206. A through hole adapted to the battery sorting port 202 is provided on the current-limiting plate 207. An electric push rod 208 is installed at the end of the current-limiting plate 207. The electric push rod 208 drives the current-limiting plate 207 to move to misalign the through hole with the battery sorting port 202 to limit the downward conveyance of the battery.

[0034] Through the above technical solution, the blanking slide plate 201 is connected to the resonance disk, and single batteries are transmitted into the blanking slide plate 201 through the resonance disk. The batteries are divided and sorted by the partition plate 204 and are stacked above the battery sorting port 202 due to the blocking of the baffle 203 and the current-limiting plate 207. When the electric push rod 208 controls the current-limiting plate 207 to move so that the through hole on the current-limiting plate 207 coincides with the battery sorting port 202, the sorted batteries will fall into the lower cover below the battery guiding part 206 through the battery sorting port 202 and be continuously conveyed to the subsequent production line for capping operation, achieving the effect of improving the battery arrangement efficiency;

[0035] The entire operation can be carried out without manual intervention. The resonance disk can preliminarily arrange and convey the batteries. The working time difference of its electric push rod 208 can be controlled by an intelligent control device, such as connecting an image recognition device, an infrared detection device, etc., and by detecting whether the arrangement above the battery sorting port 202 is slow.

[0036] Specifically, the bottom cover conveying mechanism 1 includes a supporting device 101. A conveyor belt 102 is installed between the supporting devices 101 to convey the battery bottom cover, and the transmission efficiency of the conveyor belt 102 is controlled by a servo motor.

[0037] Through the above technical solution, the supporting device 101 mainly plays a role in supporting the entire device, and the provided conveyor belt 102 is used to convey the bottom cover, so that the bottom cover can be conveyed to a fixed point below the battery guiding part 206, and after loading the battery, it is conveyed below the upper cover conveying mechanism 3 for placing and pressing the top cover. Using a servo motor can accurately control the moving feed of the upper cover and determine the stop point.

[0038] Specifically, a plurality of bases 103 are fixedly connected to the bottom of the supporting device 101. Straight groove holes 104 are formed in the bases 103, and bolts pass through the straight groove holes 104.

[0039] Through the above technical solution, the provided bases 103 mainly play a role in facilitating fixed support, and can raise the bottom of the device to facilitate lifting and transportation by equipment such as forklifts, and the device can be installed at any position in the factory building by passing bolts through the straight groove holes 104.

[0040] Specifically, the upper cover conveying mechanism 3 includes an inclined upper cover slideway 301 which is fixedly installed. An upper cover baffle 302 is fixedly connected to the end of the upper cover slideway 301 to limit the movement of the upper cover. A blanking port 303 is formed at the bottom of the upper cover slideway 301, and the blanking port 303 enables the upper cover to fall.

[0041] Through the above technical solution, when the upper cover is conveyed into the upper cover slideway 301 by a conveying device, the upper cover will move to the position of the blanking port 303 along the slope of the upper cover slideway 301 and fall to the top of the battery, realizing automatic capping of the upper cover. The conveyance of the upper cover is intermittent rather than continuous, and the time interval of the intermittence is consistent with the conveyance rate of the bottom cover.

[0042] Specifically, the capping mechanism 4 includes a power driver 401. The power driver 401 controls a vertically installed telescopic device 402. The lower end of the telescopic device 402 is fixedly connected to a capping plate 403, and the projected area of the capping plate 403 is smaller than the projected area of the blanking port 303.

[0043] Through the above technical solution, the purpose of setting the power driver 401 is to control the telescopic device 402 to perform lifting. That is to say, the power driver 401 can be one of a hydraulic control device, a pneumatic control device, an electric control device, etc., which is set according to the equipment cost and requirements. The pressing cover plate 403 is used to press the upper cover during the descending process, so that the upper cover, the battery, and the lower cover are tightly connected.

[0044] Specifically, the pressing cover plate 403 is located directly above the blanking port 303. After the pressing cover plate 403 descends, it penetrates through the blanking port 303 to press the upper cover of the battery.

[0045] Through the above technical solution, the pressing cover plate 403 is set directly above the blanking port 303, so that the pressing cover plate 403 can directly penetrate through the blanking port 303 to press the upper cover, reducing the occupied space of the equipment. To ensure the safety of the battery, a pressure sensor can be set below the pressing cover plate 403 to limit the pressure.

[0046] Specifically, a rigid support 105 is fixedly connected between the conveyor belts 102. The rigid support 105 is located directly below the pressing cover plate 403 to support the conveyor belts 102.

[0047] Through the above technical solution, the purpose of setting the rigid support 105 is to enhance the strength of the pressing cover. When the rigid support 105 is not set, the top of the conveyor belt 102 will be deformed due to the pressure, thus weakening the pressure of the pressing cover plate 403 and resulting in a poor pressing effect.

[0048] During use, by setting the blanking slide plate 201 to be connected to the resonance plate, single batteries are transmitted into the interior of the blanking slide plate 201 through the resonance plate. The batteries are separated and sorted by the partition plate 204 and are stacked above the battery sorting port 202 due to the blocking of the baffle 203 and the current limiting plate 207. When the electric push rod 208 controls the movement of the current limiting plate 207 so that the through hole on the current limiting plate 207 coincides with the battery sorting port 202, the sorted batteries will fall into the lower cover below the battery guiding portion 206 through the battery sorting port 202 and are continuously conveyed to the subsequent production line for the pressing cover operation, achieving the effect of improving the battery arrangement efficiency.

[0049] The lower cover is positioned and conveyed by the conveyor belt 102, and the batteries are arranged by the cooperation of the partition plate 204 and the battery sorting port 202 inside the blanking slide plate 201. At the same time, the upper cover slideway 301 is connected to the transmission equipment to convey the upper cover. Finally, after the lower cover, the battery, and the upper cover are stacked and coincided, the power driver 401 controls the telescopic device 402 to work to make the pressing cover plate 403 descend to realize the pressing cover operation, achieving the effect of enabling assembly line operation.
