[0007] The power supply box is installed on a carrier, and a first plug-in terminal on the power supply box is connected to a first socket of a second plug-in terminal on the carrier through a tooling wire harness, and the connection is completed in the previous installation process of accessories; the manual work station is used to disassemble the tooling wire harness, and the manual work station is located on one side of the installation station of the accessories;

[0008] At both the electrical performance test station and the insulation withstanding voltage test station, there is a terminal automatic plugging mechanism. The terminal automatic plugging mechanism includes a third plugging terminal and a plugging component. One side of the third plugging terminal is connected to the electrical performance test equipment or the insulation withstanding voltage test equipment; the plugging component is used to drive the third plugging terminal to be connected to the second plugging port of the second plugging terminal;

[0009] The transfer equipment includes a first conveying mechanism, a second conveying mechanism, a third conveying mechanism and a transfer mechanism. The first conveying mechanism is used to transfer the carrier between the electrical performance test equipment and the insulation withstanding voltage test equipment. The transfer mechanism is used to transfer the carrier between the first conveying mechanism, the second conveying mechanism and the third conveying mechanism; the second conveying mechanism is used to convey the carrier to the manual station; the third conveying mechanism is used to convey the carrier to the next process.

[0010] Furthermore, the second conveying mechanism and the third conveying mechanism are respectively located on both sides of the first conveying mechanism; the second conveying mechanism is arranged parallel to the first conveying mechanism, and the third conveying mechanism is arranged perpendicular to the first conveying mechanism; the transfer mechanism is arranged parallel to the third conveying mechanism.

[0011] Furthermore, at both the electrical performance test station and the insulation withstanding voltage test station, there is a positioning component, and the positioning component is used to position the position of the carrier.

[0012] Furthermore, the plugging ends of the second plugging terminal and the third plugging terminal are of a pin board structure.

[0013] Furthermore, at the electrical performance test station and the insulation withstanding voltage test station, there is a jacking mechanism respectively, and the jacking mechanism is used to jack up the carrier on the first conveying mechanism.

[0014] Furthermore, the transfer mechanism includes a bracket, a lateral driving component, a vertical driving component and a clamping component; the bracket is fixed on the workbench, the lateral driving component is installed on the bracket, the vertical driving component is installed on the driving end of the lateral driving component, and the clamping component is installed on the driving end of the vertical driving component; the lateral driving component is used to drive the vertical driving component and the clamping component to operate between the first conveying mechanism, the second conveying mechanism and the third conveying mechanism; the vertical driving component is used to drive the clamping component to move vertically; the clamping component is used to clamp both sides of the carrier.

[0015] Furthermore, the clamping component includes a clamping driving part and two groups of clamping structures. Each group of clamping structures includes a clamping frame and at least one group of supporting blocks. The clamping driving part is used to drive the clamping frames of the two groups of clamping structures to approach or move away from each other; the supporting blocks are arranged perpendicular to the clamping frames and the supporting blocks are arranged horizontally; the supporting blocks are used to support the carrier, and the inner sides of the clamping frames are used to clamp the carrier.

[0016] Further, the positions where the vehicle contacts the power supply box are all made of insulating materials.

[0017] Further, a safety light curtain is provided at the manual work station.

[0018] The working principle of this technical solution is as follows: After the power supply box goes through the disassembly of the power supply box cover plate, the application of thermal conductive grease, the installation of the power module, the tightening of the power module screws, and the installation of accessories (performed manually), it is transported to the first conveying mechanism. In the previous process, the power supply box has been accurately positioned on the vehicle.

[0019] Assume that the insulation withstand voltage test is carried out first and then the electrical performance test. The first conveying mechanism transports the vehicle. When the vehicle moves to the position of the positioning component at the insulation withstand voltage test station, the lifting mechanism at the insulation withstand voltage test station lifts the vehicle. Then the plugging component at the insulation withstand voltage test station drives the third plugging terminal to move towards the second plugging terminal to achieve the plugging of the two. After the plugging is completed, the insulation withstand voltage test equipment conducts the insulation withstand voltage test. After the insulation withstand voltage test is completed, the plugging component retracts, and the second plugging terminal and the third plugging terminal are separated. The lifting mechanism descends, and the vehicle returns to the first conveying mechanism to continue the transportation. When the vehicle moves to the position of the positioning component at the electrical performance test station, the electrical performance test is carried out according to the above steps.

[0020] After the electrical performance test is completed, the plugging component retracts, and the second plugging terminal and the third plugging terminal are separated. At this time, the lifting mechanism does not descend. The lateral driving component and the vertical driving component drive the clamping component to move to the position of the vehicle, and the support blocks are located on both sides of the vehicle. Then the clamping driving part is started, and the clamping driving part drives the support blocks to move through the clamping frame. The support blocks slide under the vehicle until the inner side of the clamping frame abuts against the vehicle to achieve clamping.

[0021] Then the lateral driving component is started, and the lateral driving component drives the vehicle to move above the second conveying mechanism. Then the vertical driving component is started, and the vertical driving component drives the vehicle to descend onto the second conveying mechanism. Then the clamping driving part drives the support blocks to move away from each other. The second conveying mechanism transports the vehicle to the manual work station, and the worker manually removes the tooling wire harness. Then the second conveying mechanism transports the vehicle in the reverse direction to the starting position. The clamping driving part drives the support blocks to move closer to each other to clamp the vehicle. After that, the lateral driving component drives the vehicle to move onto the third conveying mechanism, and the third conveying mechanism transports the tested vehicle to the next process.

[0022] The beneficial effects of this technical solution are as follows:

[0034] As Figure 4 shown, the power supply box 11 is installed on the carrier 10, and the carrier 10 is provided with a placement groove for placing the power supply box 11. The positions where the carrier 10 contacts the power supply box 11 are all made of insulating materials. The carrier 10 is provided with a second plug-in terminal 24, and the first plug-in interface 23 of the second plug-in terminal 24 is connected to the first plug-in terminal 20 of the power supply box 11 through a tooling wire harness, and the connection is completed manually in the installation process of the previous accessories. The manual work station 3 is used to disassemble the tooling wire harness. The manual work station 3 is located on one side of the accessory installation station 4, and the two stations are close to each other.

The second conveying mechanism 8 is arranged in parallel with the first conveying mechanism 7, and the third conveying mechanism 9 is arranged perpendicular to the first conveying mechanism 7. The transfer mechanism 6 is arranged in parallel with the third conveying mechanism 9. In this embodiment, both the first conveying mechanism 7 and the third conveying mechanism 9 use conveying rollers arranged on both sides for conveying. The lifting mechanism is located between the conveying rollers on both sides. The second conveying mechanism 8 uses a linear module for transmission, and a blocking block is provided on one side of the second conveying mechanism 8 close to the manual workstation 3.

[0037] Positioning components are provided at both the electrical performance testing station 2 and the insulation withstand voltage testing station 1. The positioning components are used to position the position of the carrier 10. The positioning components can use sensors connected to the control system for positioning. It can also be achieved by using a swing cylinder and a swing block. The swing cylinder is connected to the control system. The swing cylinder is located below the electrical performance testing station 2 and the insulation withstand voltage testing station 1. The swing cylinder drives the swing block to rotate. Therefore, the swing block can be completely located below the carrier 10, and the swing block can also be rotated above to block the carrier 10.

[0038] Lifting mechanisms are respectively provided at the electrical performance testing station 2 and the insulation withstand voltage testing station 1. The lifting mechanisms are used to lift the carrier 10 on the first conveying mechanism 7. The lifting mechanism includes a lifting driving member (using a cylinder or other linear driver) and a lifting plate. The lifting driving member is connected to the control system.

[0039] As described in 3, the transfer mechanism 6 includes a bracket 12, a lateral drive assembly 13, a vertical drive assembly 14, and a clamping assembly; the bracket 12 is fixed to the workbench, the lateral drive assembly 13 is installed on the bracket 12, the vertical drive assembly 14 is installed at the drive end of the lateral drive assembly 13, and the clamping assembly is installed at the drive end of the vertical drive assembly 14.

The clamping drive member 15 can be a double-headed cylinder. The support blocks 17 are perpendicularly arranged with respect to the clamping frame 16 and the support blocks 17 are horizontally arranged; the support blocks 17 are used to support the carrier 10, and the inner side of the clamping frame 16 is used to clamp the carrier 10. The lateral drive assembly 13 is further provided with a guide sleeve 18. The drive end of the vertical drive assembly 14 is connected with a connecting plate, and a guide rod 19 is connected to the connecting plate. The guide rod 19 is slidably connected in the guide sleeve 18 to achieve vertical guidance.

[0040] The specific implementation process is as follows:

[0041] After the power supply box 11 undergoes disassembly of the power supply box cover, application of thermal conductive grease, installation of the power module, tightening of the power module screws, and installation of accessories (performed manually), it is transferred to the first conveying mechanism 7. In the previous process, the power supply box 11 has been accurately positioned on the carrier 10.

[0042] Assuming that the insulation withstand voltage test is performed first and then the electrical performance test, the first conveying mechanism 7 transports the carrier 10. When the carrier 10 moves to the positioning component position at the insulation withstand voltage test station 1, the lifting mechanism at the insulation withstand voltage test station 1 lifts the carrier 10. Then, the plugging component at the insulation withstand voltage test station 1 drives the third plugging terminal 22 to move towards the second plugging terminal 24 to achieve plugging of the two. After plugging is completed, the insulation withstand voltage test equipment performs the insulation withstand voltage test. After the insulation withstand voltage test is completed, the plugging component retracts, and the second plugging terminal 24 and the third plugging terminal 22 are separated. The lifting mechanism descends, and the carrier 10 returns to the first conveying mechanism 7 to continue transportation. When the carrier 10 moves to the positioning component position at the electrical performance test station 2, the electrical performance test is performed according to the above steps.

[0043] After the electrical performance test is completed, the plugging component retracts, and the second plugging terminal 24 and the third plugging terminal 22 are separated. At this time, the lifting mechanism does not descend. The lateral driving component 13 and the vertical driving component 14 drive the clamping component to move to the position of the carrier 10, and the support blocks 17 are located on both sides of the carrier 10. Then the clamping driving member 15 is started, and the clamping driving member 15 drives the support blocks 17 to move through the clamping frame 16. The support blocks 17 slide from the bottom of the carrier 10 until the inner sides of the clamping frames 16 abut against the carrier 10 to achieve clamping.

[0044] Then the lateral driving component 13 is started, and the lateral driving component 13 drives the carrier 10 to move above the second conveying mechanism 8. Then the vertical driving component 14 is started, and the vertical driving component 14 drives the carrier 10 to descend onto the second conveying mechanism 8. Then the clamping driving member 15 drives the support blocks 17 to move away from each other. The second conveying mechanism 8 conveys the carrier 10 to the manual work station 3, and the worker manually removes the tooling wire harness. Then the second conveying mechanism 8 conveys in the reverse direction and conveys the carrier 10 to the starting position. The clamping driving member 15 drives the support blocks 17 to approach each other to clamp the carrier 10. After that, the lateral driving component 13 drives the carrier 10 to move onto the third conveying mechanism 9, and the third conveying mechanism 9 conveys the tested carrier 10 to the next process.
