[0025] Specifically, in order to load the PCM board, a storage mechanism 10 is provided on one side of the frame, wherein two storage mechanisms 10 are provided, and when the transfer mechanism 50 has finished loading the PCM board of one storage mechanism 10, the PCM board of the other storage mechanism 10 is loaded. Figure 2As shown, the storage mechanism 10 includes a material cart 11, on which a discharge station 12 with stacked material trays is provided, and a code disc assembly 13 is provided on one side of the discharge station 12. A plurality of PCM boards are mounted on the material trays. The transfer mechanism 50 transfers the stacked material trays on the discharge station 12 to the code disc assembly 13, and then positions the material trays through the code disc assembly 13, wherein the code disc assembly 13 is composed of a cylinder and a positioning block, to ensure the accurate position of the PCM board, thereby ensuring that the transfer mechanism 50 can accurately grab the PCM board on the material tray. Among them, a height detection assembly 14 is provided above the discharge station 12, and when the material trays of the material cart 11 on one of the storage mechanisms 10 are transferred, the transfer mechanism 50 loads the PCM board of another storage mechanism 10, and at this time, the empty material cart 11 can be replaced manually.

[0026] Further, such as Figure 4-5 As shown, the positioning mechanism 20 includes a mounting seat 25, a carrier 21 disposed on the mounting seat 25 and used to place the PCM board, and a first positioning component 22, a second positioning component 23 and a third positioning component 24 disposed around the carrier 21. When the transfer mechanism 50 transfers the PCM board to the carrier 21, and then fixes the PCM board on the carrier 21, the first positioning component 22, the second positioning component 23 and the third positioning component 24 are used to shape the two pads of the PCM board to ensure the flatness of the pads, and the two pads are respectively welded to the positive and negative electrodes of the battery.

[0027] In the above scheme, the first positioning assembly 22 includes a slider 221 slidably disposed on the mounting seat 25 toward the carrier 21, a first driver 222 disposed on the slider 221, and a support block 223 connected to the driving end of the first driver 222, and the first driver 222 drives the support block 223 to move up and down. A cylinder for driving the slider 221 to move is disposed on the bottom surface of the mounting seat 25, and the first driver 222 is a driving cylinder. The first driver 222 drives the support block 223 to move up and down, thereby causing the support block 223 to press down to flatten and shape the pad of the PCM board.

[0028] Furthermore, in order to realize the transfer of PCM board, such as Figure 3 As shown, the transfer mechanism 50 includes a robot arm 51, and a clamp assembly 52 and a suction cup assembly 53 are connected to the execution end of the robot arm 51. The suction cup assembly 53 is used to transfer the material tray of the material placement station 12 on the material cart 11 to the code disc assembly 13. The clamp assembly 52 is used to grab the PCM board on the code disc assembly 13, and then transfer the PCM board. The clamp assembly 52 can be a cylinder clamp, and the clamp assembly 52 is provided with at least two groups, so that two PCM boards are loaded.

[0029] Further, such as Figure 6-7As shown, the welding mechanism 40 includes a pressing assembly 42 and a laser welding assembly 41 arranged above the conveying path of the battery conveying mechanism 30. The battery conveying mechanism 30 transfers the battery to the bottom of the pressing assembly 42, and then the transfer mechanism 50 places the PCM board on the battery of the battery conveying mechanism 30, and then the pressing assembly 42 is pressed down to fix the welding pad of the PCM board on the battery's tab. The laser welding assembly 41 is located above the pressing assembly 42, and the laser welding assembly 41 is used to perform laser welding on the PCM board and the battery's tab.

[0030] Furthermore, the welding mechanism 40 further includes a displacement driving component 43, on which the pressing component 42 is disposed, and the displacement driving component 43 drives the pressing component 42 to move along the conveying direction of the battery conveying mechanism 30. The position of the pressing component 42 is then adjusted by the displacement driving component 43, so that the pressing component 42 can accurately fix the welding pad of the PCM board on the battery tab, wherein the pressing claw of the pressing component 42 is provided with a notch, and then the laser of the laser welding component 41 located above the pressing component 42 passes through the notch to weld the PCM board.

[0031] Furthermore, the battery conveying mechanism 30 is provided with a loading jig 31. For example, the loading jig 31 is conveyed by a conveyor belt, and a mounting plate 32 for vertically inserting the battery is provided on the loading jig 31. Since the battery is wrapped with a steel shell, and then the exposed tabs are welded to the PCM board, compared with the soft-pack battery, the soft-pack battery can only be placed horizontally, and the tabs are extended and welded to the pads of the PCM board, while the battery cell wrapped with a steel shell can be placed vertically and welded, such as Figure 8 As shown, the welding accuracy can be improved.

[0032] In the above scheme, it also includes a visual inspection component 60 arranged on one side of the storage mechanism 10. Before the transfer mechanism 50 places the PCM board on the battery, the PCM board needs to be inspected. Therefore, the PCM board is inspected by the visual inspection component 60 to ensure that the shape and model of the PCM board are accurate. A material unloading conveyor belt 61 is arranged on one side of the visual inspection component 60. When the inspection fails, the PCM board is placed on the material unloading conveyor belt 61, and the unqualified PCM board is conveyed and unloaded.

[0033] In summary, the present application scheme is provided with a positioning mechanism on one side of the material storage mechanism, the positioning mechanism is used to position and shape the PCM board, a battery conveying mechanism is provided on one side of the positioning mechanism, the battery conveying mechanism is used to convey and load the battery, a transfer mechanism is used to transfer the PCM board on the material storage mechanism to the positioning mechanism and the battery conveying mechanism in sequence, a welding mechanism is provided above the battery conveying mechanism, the welding mechanism is used to press and weld the PCM board to the battery ear, the positioning mechanism is used to shape the pad on the PCM board, the PCM board is transferred to the battery of the battery conveying mechanism through the transfer mechanism, and then the PCM board is pressed on the battery ear through the welding mechanism, and the welding mechanism then welds the pad of the PCM board to the battery, thereby realizing fully automatic loading and welding of the battery and PCM board, improving production efficiency, and at the same time improving welding accuracy.
