[0019] The working principle of this technical solution is as follows: The transfer unit moves above the power supply box loading unit, identifies the position of the power supply box through the upper vision system, and then grabs the power supply box to the power supply box flipping unit and locates it between two groups of power supply box positioning members. Then the clamping drive mechanism drives the base and the clamping seat to approach each other, so that the power supply box is clamped by the power supply box positioning members on both sides, and the transfer unit immediately releases the power supply box. After that, the flipping assembly starts to flip, changing the power supply box from a vertical state to a horizontal state; at the same time, the transfer unit will replace the corresponding mechanical claw to match the power supply box in the horizontal state. Then the transfer unit grabs the power supply box in the horizontal state again, and the clamping drive mechanism drives the base and the clamping seat to move away from each other.

[0020] The transfer unit transfers the power supply box above the carrier on the cover plate disassembly unit, identifies the position of the carrier slot on the carrier through the upper vision system, then places the power supply box in the carrier slot, and then starts the lateral drive member and the vertical drive member. The lateral drive member and the vertical drive member drive the lateral positioning member and the vertical positioning member to move, so that the four sides of the power supply box are positioned by the lateral fixing member, the vertical fixing member, the lateral positioning member and the vertical positioning member. The upper vision system of the transfer unit identifies the position of the positioned power supply box, and the screw disassembler disassembles the screws according to the identified data and places the disassembled screws in the screw receiving box. After the screws are disassembled, the transfer unit lifts the cover plate upward, then the pushing cylinder drives the pushing rod to move, pushing the isolation column into the waste collection box, and then the pushing cylinder drives the pushing rod to reset. Then the transfer unit transfers the cover plate to the cover plate placement position on the carrier. After that, the transfer unit transfers the protective film to the waste collection box.

[0021] Then start the first transfer unit and the second transfer unit, so that the vehicle is transferred from the first transfer unit to the second transfer unit. At the same time, the swing cylinder at the coating unit swings upward, and the vehicle positioning member positions the vehicle. Then start the second positioning unit at the coating unit to position the power supply box. After positioning, the coating machine identifies the coating position inside the power supply box and coats thermal grease. At the same time, the transfer unit moves to the power module loading unit, identifies the position of the power module through the upper vision system, and takes out the power module. Then it moves to the lower vision system for code scanning and identification, and identifies whether the grasping position of the power module meets the requirements. After identifying that the information of the power module meets the installation requirements of the power supply box, transfer the power module to the coating unit. Then, after the upper vision system on the transfer unit identifies the installation position of the power module in the power supply box, place the power module in the power supply box. Determine the number of power modules to be installed according to the type of the power supply box.

[0022] After the power module is placed, start the second transfer unit, the fifth transfer unit and the third transfer unit. The vehicle on the second transfer unit is transferred to the power module locking unit through the fifth transfer unit and the third transfer unit. At the same time, the swing cylinder at the power module locking unit swings upward, and the vehicle positioning member positions the vehicle. Then the second positioning unit at the power module locking unit positions the power supply box. Then the positioning vision system on the screw locking machine identifies the screw locking position of the power module and performs locking. The locked power supply box will be transported to the accessory installation station for accessory installation, including quick plug module assembly, terminal and guide rail assembly, wiring, etc. The power supply box with assembled accessories will be transported to the test station for testing. After passing the test, processes such as nameplate marking, anti-rust oil coating on the shell, cover plate assembly, and certificate sticker pasting will be carried out.

[0023] The empty vehicle or the vehicle with a repaired power supply box will be transferred to the position between the coating unit and the power module locking unit through the fourth transfer unit. Then start the lifting part, and the lifting part drives the transfer part to rise to the same height as the second transfer unit. Then start the transfer part, the second transfer unit and the first transfer unit to transfer the vehicle to the cover plate disassembly unit position, and then the next round of assembly can be carried out.

[0024] The beneficial effects of this technical solution are as follows: By setting up the power supply box loading unit, the power module loading unit, the transfer unit, the cover plate disassembly unit, the coating unit and the power module locking unit, this technical solution can realize the automatic loading of the power supply box and the power module, the automatic disassembly of the cover plate, the automatic coating of thermal grease, and the automatic locking of the power module, reducing the participation of manual labor and improving the assembly efficiency and automation level.

The power supply box in the power supply box loading trolley is placed vertically, which can increase the accommodation capacity of the power supply box loading trolley. At the same time, a power supply box flipping unit is provided to transform the power supply box.

[0052] The specific implementation process is as follows:

[0053] The transfer unit 1 moves above the power supply box loading unit 2, identifies the position of the power supply box 7 through the upper vision system, and then grabs the power supply box 7 to the power supply box flipping unit 14 and positions it between two groups of power supply box positioning members 19. Then the clamping drive mechanism 15 drives the base 16 and the clamping seat 17 to approach each other, so that the power supply box positioning members 19 on both sides clamp the power supply box 7, and the transfer unit 1 immediately releases the power supply box 7. After that, the flipping assembly 18 starts to flip, changing the power supply box 7 from the vertical state to the horizontal state; at the same time, the transfer unit 1 will replace the corresponding mechanical claw to match the power supply box 7 in the horizontal state. After the transfer unit 1 replaces the mechanical claw, it grabs the power supply box 7 in the horizontal state again, and the clamping drive mechanism 15 drives the base 16 and the clamping seat 17 to move away from each other.

[0054] The transfer unit 1 transfers the power supply box 7 above the carrier 36 on the cover plate disassembly unit 4, identifies the position of the carrier slot on the carrier 36 through the upper vision system, and then places the power supply box 7 in the carrier slot. Then the lateral drive member 26 and the vertical drive member 24 are started, and the lateral drive member 26 and the vertical drive member 24 drive the lateral positioning member 27 and the vertical positioning member 25 to move, so that the lateral fixing member 23, the vertical fixing member 22, the lateral positioning member 27 and the vertical positioning member 25 position the four sides of the power supply box 7. The upper vision system of the transfer unit 1 takes a photo and identifies the position of the positioned power supply box 7, and sends the identification data to the control unit. The control unit sends an instruction to the screw disassembly machine 21, and the screw disassembly machine 21 disassembles the screws according to the identified data and places the disassembled screws in the screw receiving box 28. After the screws are disassembled, the transfer unit 1 sucks the cover plate and lifts it by 10 mm, and then the push rod of the push rod cylinder drives the push rod to move, pushing the isolation column into the waste collection box, and then the push rod cylinder drives the push rod to reset. After that, the transfer unit 1 transfers the cover plate to the cover plate placement position on the carrier 36 (since the isolation column may stick to the cover plate, so the cover plate is lifted first, so that the isolation columns that are brought up by the cover plate and the isolation columns that are not brought up and remain on the bottom shell can be pushed at the same time to prevent the isolation columns from running around). After that, the transfer unit 1 transfers the protective film to the waste collection box.

[0055] Then, start the first transfer unit and the second transfer unit, so that the vehicle 36 is transferred from the first transfer unit to the second transfer unit. At the same time, the swing cylinder 34 at the coating unit 5 swings upward, and the vehicle positioning member 35 positions the vehicle 36. Then, start the second positioning unit at the coating unit 5 to position the power supply box 7. After positioning, the positioning vision system of the coater identifies the coating position in the power supply box 7 and applies thermal conductive silicone grease. At the same time, the transfer unit 1 moves to the power module loading unit 3, identifies the position of the power module 9 through the upper vision system, and takes out the power module 9. Then, it moves to the lower vision system for code scanning and identification, and takes a photo to identify whether the grasping position of the power module 9 meets the requirements. After identifying that the information of the power module 9 meets the installation requirements of the power supply box 7, the power module 9 is transferred to the coating unit 5. Then, after the upper vision system on the transfer unit 1 identifies the installation position of the power module 9 in the power supply box 7, the power module 9 is placed in the power supply box 7.
