The lifting driving mechanism of the present application is preferably a pneumatic cylinder. When the disc gear is conveyed to below the cleaning device or the brushing device, the lifting driving mechanism is actuated upward to make the V-shaped limiting block rise and stop at the side of the disc gear.

[0045] With reference to Figure 2 , Figure 10 and Figure 11 , the above-mentioned turnover module 2 comprises a turnover rack 61, a turnover frame mechanism 62, a first pushing mechanism 63, a second pushing mechanism 64 and a transverse pushing mechanism 65. The first pushing mechanism 63, the turnover frame mechanism 62, the second pushing mechanism 64 and the transverse pushing mechanism 65 are sequentially arranged on the turnover rack 61 and extend from one end to the other end of the first conveying module.

[0046] With reference to Figure 10 and Figure 11 , the above-mentioned first pushing mechanism comprises a first pushing block 631 and a first pushing cylinder 632, the second pushing mechanism comprises a second pushing block 641, a vertical lifting cylinder 642 and a second pushing cylinder 643, the turnover rack 61 is provided with a pushing guide rail 611 at the lower part, the first pushing cylinder 632 and the second pushing cylinder 643 are respectively installed on the pushing guide rail 611, the piston rod end of the first pushing cylinder 632 is connected with the first pushing block 631 through a first connecting rod 633, the piston rod end of the top end of the vertical lifting cylinder 642 fixedly installed on the piston rod end of the second pushing cylinder 643 is connected with the second pushing block 641; the transverse pushing mechanism comprises a third pushing block 651 and a third pushing cylinder 652, the third pushing cylinder 652 is fixed on the side of the turnover rack 61 corresponding to the front end of the second conveying module 3, and the piston rod end of the third pushing cylinder 652 is connected with the third pushing block 651.

The turnover frame 621 is rotatably installed on the turnover rack 61 through the turnover shaft 622, and the turnover motor 623 is fixed on the side of the turnover rack 61 and connected with the turnover shaft 622 through the output shaft.

[0048] The above motors, cylinders, solenoid valves and the like are in communication connection with the PLC controller 4, and the action thereof is controlled by the PLC controller 4.

[0049] The specific process of the production line is as follows:

[0050] I. Place the disc gear on the first conveying module with the end face having the stepped groove facing upward.

[0051] II. When it is conveyed to the cleaning device, the lifting driving mechanism of the gear limiting device acts upward to make the V-shaped limiting block rise on the side of the disc gear, and then the solenoid valve of the cleaning device is opened to clean the surface of the disc gear by rotating the rotating disc to drive the cleaning sponge.

[0052] III. After drying, it is conveyed to below the detection device, the surface of the disc gear is photographed by the camera and transmitted to the PLC controller for analysis. If there is a defect, the first conveying module is paused for conveying by the PLC controller, and the disc gear is taken out by the worker; if there is no defect, it continues to be conveyed to the brushing device.

[0053] IV. When reaching the brushing device position, the disc gear is limited by the gear limiting device, the lifting cylinder of the gear positioning rotating mechanism acts upward to drive the rotating seat to rise, the elastic clamping piece is clamped into the mounting hole of the disc gear to position the disc gear; then the glue dropping mechanism works to drop the anti-seepage coating to the position needing to be coated on the disc gear; then the rotating seat drives the disc gear to rotate, and the anti-seepage coating is dispersed by the brush to make the anti-seepage coating evenly coated on each position needing to be coated. After coating is completed, the lifting cylinder acts downward to drive the rotating seat to descend, and the elastic clamping piece is separated from the disc gear under the action of the supporting piece.

[0054] V. The first conveying module continues to convey the disc gear to the turnover rack, pushes the disc gear into the turnover rack by the first pushing mechanism, then turns the turnover rack and the disc gear upward by 180° by the turnover motor, pushes the disc gear to the front of the third pushing mechanism by the second pushing mechanism, and finally pushes the turned-over disc gear to the second conveying module by the third pushing mechanism.

[0055] Since the anti-seepage coating is coated on the stepped groove bottom surface of the disc gear before turning over, when conveying after turning over, the second conveying module will not contact the anti-seepage coating, ensuring that the anti-seepage coating coating is not disturbed.

[0056] The coating method of the anti-seepage coating on the other end face of the disc gear is the same as steps II to IV, which will not be repeated here.

[0057] The above merely illustrates the specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application by using the concept shall be deemed as the infringement of the protection scope of the present application.
