Description

Technical Field

[0001] This utility model relates to the field of battery pack cell testing technology, specifically to a weighing and testing component for battery pack cells. Background Technology

[0002] A lithium-ion rechargeable battery consists of two parts: a battery cell and a protection circuit board. Removing the protection circuit board leaves the battery cell, which is the energy storage component. The quality of the battery cell directly determines the quality of the rechargeable battery.

[0003] Various tests are required in the battery cell manufacturing production line before the cells can be shipped out. Weight is one of the more important parameters. Generally, sensors are placed directly on the conveyor belt for detection. However, the quality error of the detection is large when the conveyor belt is moving. If the conveyor belt is stopped before detection, the accuracy will be improved, but this will waste time. In addition, the cells are usually stacked, so it is not possible to see the specific weight of each cell in each batch directly, which poses a certain risk of defective products. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a weighing and detection component for battery pack cells, which can take out the stacked cells one by one and realize the weighing, detection and unloading operations, with good performance.

[0005] To solve the above-mentioned technical problems, this utility model provides a weighing and detection component for battery pack cells, including a frame, on which upright plates are provided, and a crossbeam is provided between the upright plates. A moving component is provided on the crossbeam, and the moving component is provided with two cylinders and a suction cup with the same structure. A feeding mechanism, a weighing mechanism and a discharging mechanism are sequentially provided on the upper surface of the frame at the bottom of the horizontal direction. The feeding mechanism includes feeding rollers, on which feeding base plates are provided. A lifting mechanism is provided on the frame at a position corresponding to the feeding base plates. The discharging mechanism includes a rear plate fixed to one side of the upright plates, on which a track is provided. A lifting mechanism identical to that of the feeding mechanism is provided inside the frame, and a discharging lifting plate adapted to the track is provided on the top of the lifting mechanism.

[0006] Furthermore, the feeding base plate is provided with limiting angle aluminum on its periphery, the feeding base plate is provided with a through hole at its bottom, and the lifting assembly is provided with a top plate that matches the through hole at its top.

[0007] Furthermore, the weighing mechanism includes a support rod protruding from the frame, a gravity sensing component is provided at the top of the support rod, and a placement plate is provided at the top of the gravity sensing component.

[0008] Furthermore, a positioning drive device is provided on one side of the feeding roller, and a positioning plate is provided at the output end of the positioning drive device.

[0009] Furthermore, an anti-collision block is provided at the end of the feeding roller.

[0010] Furthermore, a display is provided at the top of the crossbeam, and an auxiliary controller is provided at the bottom.

[0011] The beneficial effects of this utility model are as follows: When using this device, the stacked battery cells are placed on the feeding base plate of the feeding mechanism. The lifting mechanism at the bottom can drive the battery cells to rise sequentially. The moving component first drives the cylinder to move above the feeding mechanism. The cylinder drives the suction cup to adsorb the topmost product. After adsorption, the moving component continues to drive the shovel to level the product and enter the weighing mechanism for weight detection. After detection, the suction cup continues to adsorb the product and move it to the unloading lifting plate on the final unloading mechanism. Similarly, the lifting mechanism at the bottom drives it to move up and down to adapt to different situations. The side rails are used to ensure that the feeding lifting plate does not deviate during the up and down movement. Attached Figure Description

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

A moving component 4 is provided on the crossbeam 3, and two cylinders 5 with identical structures and a suction cup 6 are provided on the moving component 4. A feeding mechanism 7, a weighing mechanism, and a discharging mechanism are sequentially provided on the upper surface of the frame 1 at the bottom of the horizontal direction. The feeding mechanism 7 includes a feeding roller 71, on which a feeding base plate 72 is provided. A lifting mechanism 10 is provided on the frame 1 at the position corresponding to the feeding base plate 72. The discharging mechanism includes a rear plate 8 fixed to one side of the upright plate 2, on which a track 9 is provided. The same lifting mechanism 10 as the feeding mechanism 7 is provided inside the frame 1, and a discharging lifting plate 11 adapted to the track 9 is provided on the top of the lifting mechanism 10.

[0022] In use, the stacked battery cells are placed on the feeding base plate 72 of the feeding mechanism 7. The lifting mechanism 10 at the bottom can drive the battery cells to rise in sequence. The moving component 4 first drives the cylinder 5 to move above the feeding mechanism 7. The cylinder 5 drives the suction cup 6 to adsorb the top product. After adsorption, the moving component 4 continues to drive the shovel to level the product and enter the weighing mechanism for weight detection. After detection, the suction cup 6 continues to adsorb the product and move it to the unloading lifting plate 11 on the last unloading mechanism. Similarly, the lifting mechanism 10 at the bottom drives it to move up and down to adapt to different situations. The side rail 9 is used to ensure that the feeding lifting plate does not deviate during the up and down movement.

[0023] The feeding base plate 72 is provided with limiting angle aluminum 73 around its perimeter. The bottom of the feeding base plate 72 is provided with a through hole 74. The top of the lifting component is provided with a top plate 75 that is adapted to the through hole 74. The limiting angle aluminum 73 is used to limit the stacked products. The lifting component drives the top plate 75 to rise. It will pass through the through hole 74 and come into contact with the product. If it continues to rise, it will push the product upward to facilitate the suction cup 6 to feed it.

[0024] The weighing mechanism includes a support rod 12 protruding from the frame 1. A gravity sensing component 13 is provided on the top of the support rod 12. A placement tray 14 is provided on the top of the gravity sensing component 13. The height of the support rod 12 depends on the height of the suction cup 6 when it is lowered and can be adjusted at will. The placement tray 14 is used to temporarily store products. The gravity sensor can detect the quality information of the products.

[0025] A positioning drive device 76 is provided on one side of the feeding roller 71. A positioning plate 77 is provided at the output end of the positioning drive device 76. An anti-collision block 78 is provided at the end of the feeding roller 71. When the feeding roller 71 moves and transports the feeding base plate 72 to contact the anti-collision block 78, it stops. The positioning drive device 76 drives the positioning plate 77 to fix the feeding base plate 72 from the side.

[0026] A display 15 is installed at the top of the crossbeam 3, and an auxiliary controller 16 is installed at the bottom.
