Specifically, the product inspection device 3 (in this embodiment, the product inspection device 3 is provided with four groups) and the loading and positioning device 6 (in this embodiment, the loading and positioning device 6 is provided with two groups, respectively used to load type A battery cells and type B battery cells) are respectively arranged on one side of the product transmission line 1, the code scanning mechanism 2 is arranged near one end of the product transmission line 1, and is located between the loading and positioning device 6 and the product inspection device 3, the jig dust removal device 4 is arranged near the other end of the product transmission line 1, and is located between the product unloading device 7 and the loading and positioning device 6; in addition, the product unloading device 7 also includes a pairing manipulator 74 installed in the product transmission line 1 and arranged near the first unloading device 71, and a pairing cache rack 73575 arranged near the pairing manipulator 74.

[0018] The loading and positioning device 6 is provided with two groups. In this embodiment, the loading and positioning device 6 includes a loading work frame 61, a first loading mechanism 62 and a second loading mechanism 63 installed on the loading work frame 61, and a loading positioning mechanism 64 arranged below the first loading mechanism 62 and the second loading mechanism 63; the first loading mechanism 62 includes a loading drive mechanism 621, a loading beam 622 slidably connected to the loading work frame 61, and a loading lifting mechanism 623 installed on one side of the loading beam 622; the loading drive mechanism 621 is connected to the loading beam 622, and the loading drive mechanism 621 is used to drive the loading beam 622 to move; the loading lifting mechanism 623 also It is driven and connected to a loading lifting frame 624, and a loading clamping claw mechanism 625 is also installed at the bottom of the loading lifting frame 624; the loading clamping claw mechanism 625 includes a clamping claw drive motor 6251, and the clamping claw drive motor 6251 is also driven and connected to two clamping claw translation seats 6252; the two clamping claw translation seats 6252 are arranged opposite to each other, and the bottom of each clamping claw translation seat 6252 is also connected to a first supporting claw module 6253; each side of the first supporting claw module 6253 is also correspondingly connected to a first clamping module 6254; the bottom of the loading lifting frame 624 is also connected to a second supporting claw module 6255, and the second supporting claw module 6255 is located between the two first supporting claw modules 6253.

[0019] The clamping jaw drive motor 6251 of the loading clamping jaw mechanism 625 can drive the two clamping jaw translation seats 6252 to move closer to or away from each other, and then clamp the product through the first clamping jaw module 6253. At the same time, a second clamping jaw module 6255 is provided. The first clamping jaw module 6253 and the second clamping jaw module 6255 can respectively support the battery from both ends and the middle, and the first clamping module 6254 can press the battery to ensure that the battery is stable and reliable during the grasping and transportation process, and can ensure that the battery is not easily deformed. The clamping jaw drive motor 6251 uses a synchronous belt or a two-way screw drive to drive the two clamping jaw translation seats 6252 to open the clamp, and there is no restriction on this.

[0020] During operation, the first loading mechanism 62 first grabs the battery from the upstream conveyor line, and after visual inspection, it is placed on the loading positioning mechanism 64. After positioning, the second loading mechanism 63 places the battery into the profiling jig 5 of the product transmission line 1; then, the product transmission line 1 carries the battery to the code scanning mechanism 2 for scanning, and then transmits it to the product inspection device 3 for photographing and imaging.

The first feeding mechanism 62 is responsible for grabbing four battery cells from the battery cell material line at a time and then placing them on the feeding positioning mechanism 64. After precise positioning, the second feeding mechanism 63 is responsible for taking materials at intervals, that is, grabbing two battery cells at a time and placing them on the product transmission line 1. On the jig (the placement method is to place one battery cell at an interval of one jig. In actual operation, there are two groups of the loading positioning devices 6, each group is used to load one type of battery cell, that is, two types A\B. The two types of battery cells are staggered with each other, and the arrangement method is ABABABAB... At the same time, the two types of battery cells are arranged side by side, that is, the pole ears are arranged perpendicular to the movement direction of the loading transmission line.), at the same time, the loading lifting mechanism 623 adopts a lifting motor, a cylinder or other modules that can drive the clamping mechanism to lift and lower, and there is no restriction on this.

Through the gear and rack transmission, the feeding beam 622 can be driven to move along the feeding slide rail assembly 6211, thereby facilitating the feeding clamp mechanism 625 to transfer products.

Simultaneously, the jaw lifting block 62555, supported by the elasticity of the second spring 62556, floats up and down. The second lifting block 62551 lifts the battery from its center position, working in conjunction with the first supporting jaw module 6253 to ensure stable and reliable battery handling. Furthermore, the bottom of the jaw drive motor 6251 is connected to a first sensing plate; this first sensing plate is positioned between the two first supporting jaw modules 6253, and a first sensor 6256 is mounted on this first sensing plate.

As mentioned above, during loading, the arrangement of the two types of battery cells A / B is ABABABAB..., and they are arranged side by side (the pole ears are perpendicular to the direction of movement). In order to meet the unloading requirements, the A / B battery cells are arranged in a butterfly shape (that is, the pole ears of the two battery cells are facing oppositely), and the pole ears of the A / B battery cells need to be close. Therefore, the battery cells need to be clamped by the first unloading manipulator 721 (the first unloading manipulator 721 is provided with two clamping claws, which can clamp two battery cells at the same time), and then the direction of the battery cells is rotated, and then placed on the unloading distance changing device 723, and then the distance is changed to a suitable distance, that is, the two battery cells are driven close to each other, and finally, the two battery cells are transferred and unloaded by the second unloading manipulator 722.

The incoming A battery cell and the incoming B battery cell are two independent logistics lines, and the battery cells are arranged in ABAB... When NG products are sorted out among the A battery cells or B battery cells, the arrangement of the battery cells ABAB will be disrupted, such as AAB or ABB.
