Driven by the conveying motor 8, the automobile component is rotated and flipped into the electrophoretic pool 13 for electrophoresis. During the electrophoresis process, the controller 2 controls the conveying motor 8 to drive the flip axis 16 to rotate the angle of the automobile component.

[0028] Working principle: When the automobile parts that need to be painted are placed at the starting end of the conveying platform 1, the controller 2 controls the transfer interface 9 to connect the conveying motor 8 and the telescopic rod 4. Driven by the conveying motor 8, the worm 29 receives the power of the conveying motor 8. The spiral teeth on the outer wall of the worm 29 engage with the worm gear 30 to transmit torque. The worm gear 30 rotates under the drive of the worm 29. The internal thread of the worm gear 30 cooperates with the spiral pair of the screw rod 28 to convert the rotational motion into the vertical lifting motion of the screw rod 28. The first valve 31 is used to adjust the flow, the second valve 32 is used for safety protection, and the sealing ring 33 is used to ensure the internal sealing of the telescopic rod 4. The telescopic rod 4 extends the four-way clamp 3 from the retracted state to the four directions of up, down, left and right, so that the contact points between the clamp 3 and the automobile parts are increased. Then the telescopic rod 4 is controlled to push the clamp 3 horizontally to make it contact with the automobile parts. Through the visual sensor 7 and the car model input by the operator, the controller 2 obtains the parameters of the automobile parts corresponding to the car model and combines them with the number of automobile parts collected by the visual sensor 7. According to the data, the controller 2 controls the adapter 9 to connect the conveying motor 8 with the rotating shaft 5, rotates the direction of the clamping block 3 in contact with the automobile part, makes the clamping block 3 fit the contact surface of the automobile part, and fixes the automobile part. The six-dimensional force sensor 10 located at the connection between the clamping block 3 and the rotating shaft 5 monitors the force and torque in the three-dimensional space when the clamping block 3 contacts the surface of the automobile part, and transmits the information to the controller 2. The controller 2 dynamically adjusts the force applied by the telescopic rod 4 to the rotating shaft 5 and the clamping block 3 to avoid deformation of the automobile part. Then the controller 2 controls the adapter 9 to connect the conveying motor 8 with the slider 6. The conveying motor 8 provides power for the slider 6, and then the automobile part continues to be conveyed on the conveying platform 1 through the slider 6 for subsequent processing. The displacement sensor 11 located on the left side of the outer wall of the slider 6 monitors the movement distance of the slider 6 on the conveying platform 1. The ultrasonic sensor 12 located on the right side of the outer wall of the slider 6 is used to monitor the distance between the automobile part and the conveying platform 1 and the conveying module to avoid collision damage to the automobile part. When the conveying motor 8 drives the slider 6 to move to the translation slot 27, the conveying module on the translation slot 27 fixes the automobile part, cancels the fixation of the automobile part by the conveying module on the other side of the conveying platform 1, and the controller 2 controls the slider 6 to move the automobile part to the translation slot 27. According to the material of the automobile part, the corresponding electrophoresis pool 13 is selected. After the slider 6 moves the automobile part to the corresponding electrophoresis pool 13, the controller 2 cancels the fixation of the flip shaft 16 by the fixer 15, connects the flip shaft 16 and the conveying motor 8 through the adapter 9, and rotates and flips the automobile part driven by the conveying motor 8 into the electrophoresis pool 13 for electrophoresis. During the electrophoresis process, the controller 2 Controlling the conveying motor 8 to drive the flip shaft 16 can rotate the angle of the automobile component. During the rotation process, the angle sensor 17 monitors the rotation angle of the flip shaft 16 and transmits the information to the controller 2, so that the automobile component can complete electrophoresis at different angles and different immersion times in the electrophoresis tank 13. After the electrophoresis of the automobile component is completed, the controller 2 controls the conveying motor 8 to drive the flip shaft 16 to flip the automobile component out of the electrophoresis tank 13. The conveying module on the other side of the conveying platform 1 resumes the fixation of the automobile component, and the conveying module on the translation slot 27 cancels the fixation of the automobile component, so that the automobile component continues to move on the conveying platform 1, which is convenient for subsequent processing. After the automobile parts have completed electrophoresis, the controller 2 controls the conveying motor 8 to drive the flip shaft 16 to flip the automobile parts out of the electrophoresis tank 13, and then controls the adapter 9 at the output end of the conveying motor 8 to connect the telescopic plate 18. Driven by the conveying motor 8, the telescopic plate 18 slides and unfolds on the guide rail 20 to form a protection under the automobile parts, isolating the bottom of the automobile parts. At the same time, the telescopic plate 18, which is in an inverted V shape and has an inclination of 3° to 5° to the horizontal plane, has a certain guiding effect on the droplets dripping from the automobile parts above the telescopic plate 18, so that they enter the reflux groove 19. After entering the V-shaped reflux groove 19, the droplets pass through the filter screen 47 under the guidance of the reflux groove 19, and then enter the purification through the recovery pipe 21. Module, when the objects blocked by the filter 47 are processed or in the processing gap, the controller 2 controls the connecting valve 46 to open, and the large particles fall into the storage box 49. The weight sensor 48 detects the weight of the material stored in the storage box 49. After the material in the storage box 49 reaches a certain weight, the controller 2 controls the connecting valve 46 below the storage box 49 to open, and the material is passed into the cleaning box 14. During the recovery of residual droplets after electrophoresis and cleaning of automobile parts, in order to avoid residual droplets on the automobile parts, after the automobile parts are flipped out of the electrophoresis tank 13, the controller 2 controls the flip axis 16 to adjust the angle of the automobile parts so that the automobile parts are in a tilted state and the droplets are completely dripped. After the painting of automobile parts is completed, the controller 2 controls the conveying motor 8 to drive the slider 6 to move the conveying module to the top of the cleaning box 14, and flips the conveying module into the cleaning box 14 through the flip module. The controller 2 controls the water inlet valve 35 to open, and at the same time controls the adapter 9 at the output end of the cleaning motor 41 to connect the push rod 36 and the cleaning motor 41. Driven by the cleaning motor 41, the push rod 36 pulls the piston 37 down to draw the cleaning liquid in the cleaning box 14 into the pressurizing chamber 40, and then pushes the piston 37 upward through the push rod 36 to pressurize the cleaning liquid in the pressurizing chamber 40 and spray it from the nozzle 39 to the conveying module to clean the conveying module. To ensure that the cleaning of the conveying module is complete, during the cleaning process of the conveying module by the cleaning nozzle 22, the controller 2 connects the rotator 34 and the cleaning motor 41 through the adapter 9 at the output end of the cleaning motor 41, and adjusts the angle of the nozzle 39. After cleaning, the cleaning liquid inside the cleaning box 14 enters the sedimentation tank 23 and is stored in the sedimentation tank 23. The PAC and PAM are coagulated, and the pigment particles and metal oxides that are stripped off are precipitated and then enter the adsorption chamber 24. The activated carbon-zeolite composite filter material filled in the adsorption chamber 24 adsorbs the dissolved organic matter and then enters the ultrafiltration unit 25. The ultrafiltration unit 25 separates the concentrated liquid containing resin and pigment and transports it into the electrochemical pool 13 through the connecting pipe. The permeate is separated and transported into the ion exchange column 26 through the connecting pipe. The strong alkaline anion exchange resin in the ion exchange column 26 removes the metal ions. The permeate after the metal ions are removed flows back into the cleaning box 14 through the connecting pipe. After cleaning, the conveying module is turned back by the turning module. The controller 2 controls the cleaning motor 41 to connect with the fan 42. The cleaning motor 41 drives the fan 42 to rotate, and the heat generated by the heating wire 43 is evenly diffused inside the dust cover 45. The temperature inside the dust cover 45 is detected by the temperature sensors 44 located on the left and right sides of the dust cover 45, and the conveying module is dried.
