[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention provides a workpiece clamping assembly at the bottom end of the unwinding cable, and when the lower positioning fixture clamps the workpiece, the workpiece is placed in a pretreatment box for impurity removal and micro-arc electrophoresis is performed on the unclamped position. After the upper positioning fixture clamps the workpiece, the lower positioning fixture releases the limit, and micro-arc electrophoresis is continued on the clamping position of the lower positioning fixture. All surfaces of the workpiece are electrophoresed evenly, which helps to ensure the uniformity and quality stability of the electrophoretic coating, improves the uniformity and density of the electrophoretic coating, helps to improve the corrosion resistance and wear resistance of the coating, and extends the service life of the workpiece. The uniform electrophoretic coating can make the workpiece surface smoother and brighter. The uniform coating ensures that the workpiece has stable performance in different environments, reducing damage to the workpiece caused by corrosion or wear during use.

[0031] 2. The present invention provides a scrubbing treatment component on the top of the upper positioning fixture. The ultrasonic vibration of the degreasing liquid during the degreasing process of the workpiece enhances the degreasing effect. The scrubbing treatment component performs auxiliary wiping on the outer side of the upper end of the workpiece. The auxiliary wiping of the scrubbing treatment component can further remove the oil stains that are difficult to reach and improve the degreasing effect. The auxiliary wiping of the scrubbing treatment component can ensure that the surface of the workpiece is cleaner, thereby improving the quality and adhesion of the electrophoretic coating and avoiding problems such as uneven coating, bubbles, and shedding after electrophoresis. The auxiliary wiping of the scrubbing treatment component can quickly and effectively remove oil stains and other impurities on the surface of the workpiece, shorten the degreasing time, and improve production efficiency.

[0032] 3. The present invention has a tightening guide wheel rotatably installed on the inner side of the guide wheel frame. During the unwinding process of the unwinding cable, the tightening guide wheel cooperates with the damper to guide it, and adjusts the winding and bending direction of the unwinding cable to restore it to flatness, so that the internal material of the unwinding cable is evenly stressed, and damage caused by excessive bending and winding of the unwinding cable on the unwinding guide wheel is avoided, thereby extending the service life of the unwinding cable and ensuring the stability of the unwinding cable when pulling and transmitting the workpiece. The flatness of the unwinding cable can reduce potential safety hazards caused by friction or extrusion, further reduce the shaking amplitude of the workpiece when it moves, and improve the safety performance of the workpiece during micro-arc electrophoresis.

[0033] 4. In the present invention, an anti-vibration weight is fitted and installed inside the weight slot. The installation quantity and position of the anti-vibration weight are selected according to the weight and specification of the workpiece. The anti-vibration weight is installed and clamped inside the weight slot. The limit bolt sequentially passes through the inside of the perforation and the threaded hole to realize the installation limit of the anti-vibration weight. The anti-vibration weight increases the weight of the unwinding cable, effectively reducing the shaking and fluctuation generated during the process of the unwinding cable driving the workpiece to move. Thus, the workpiece maintains a more stable moving state during the electrophoresis process, which helps to ensure the uniformity and consistency of the workpiece during the electrophoresis process, improve the electrophoresis effect. The reduction of shaking also reduces the contact friction between the workpiece and the electrophoresis equipment, reducing equipment wear. The stable moving state can reduce the risk of accidental collision or workpiece detachment caused by shaking, improving the safety of the entire electrophoresis process. The stable movement of the workpiece helps to maintain the continuity during the electrophoresis process, reducing the pause and adjustment time caused by shaking, and improving the micro-arc electrophoresis efficiency.

[0048] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , an embodiment provided by the present invention: a micro-arc electrophoresis production line with an automatic blanking function and its usage method;

[0049] It includes a production unwinding box 3, an unwinding cable 5 and a workpiece clamping assembly. Above the electrophoresis production seat 1, there is a gantry 14. At the top center position of the gantry 14, a production unwinding box 3 is installed. On the bottom wall of the production unwinding box 3, a support frame 19 is installed. Inside the support frame 19, a unwinding guide wheel 20 is installed through a rotating shaft. The outside of the unwinding guide wheel 20 is wound with an unwinding cable 5. At the bottom end of the unwinding cable 5, there is a workpiece clamping assembly. The workpiece clamping assembly includes a top contact frame 6, a fixing plate 35, clamping hand rods 36 and a positioning fixture 37. The top contact frame 6 is connected to the bottom end of the unwinding cable 5. The fixing plate 35 is installed at the bottom of the top contact frame 6. Two groups of clamping hand rods 36 are symmetrically installed inside the fixing plate 35. The positioning fixture 37 is installed at the telescopic end of the clamping hand rod 36. On the opposite side of the positioning fixture 37, a rubber insulating pad 38 is installed;

[0050] The guide rail 13 drives the gantry 14. An opening is penetrated at the top center position of the gantry 14 to facilitate the winding and unwinding of the unwinding cable 5. The two groups of positioning fixtures 37 are arranged vertically. The lower positioning fixture 37 clamps the workpiece under the pushing action of the clamping hand rod 36. The unwinding cable 5 drives the clamped workpiece to move under the driving action of the gantry 14. After clamping, the unwinding cable 5 drives the workpiece clamping assembly and the workpiece to move together, and the workpiece is placed in the pretreatment box 49 for impurity removal operation and micro-arc electrophoresis is performed on the unclamped position of the workpiece. After the upper positioning fixture 37 clamps the workpiece, the lower positioning fixture 37 releases the limit, and micro-arc electrophoresis is continued on the clamping position of the lower positioning fixture 37. Electrophoresis of all surfaces of the workpiece evenly helps to ensure the uniformity and quality stability of the electrophoresis coating, improves the uniformity and denseness of the electrophoresis coating. The uniform electrophoresis coating can make the surface of the workpiece smoother and brighter, reducing the damage of the workpiece caused by corrosion or wear during use. The rubber insulating pad 38 increases the contact clamping force between the rubber insulating pad 38 and the workpiece while the clamping position needs to be insulated to prevent unnecessary current from passing through. The coverage of the rubber insulating pad 38 can ensure that the clamping position of the fixture will not be covered by the electrophoresis coating, and at the same time, it will not affect the electrophoresis effect of other parts of the workpiece.

[0051] Please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 9 , a micro-arc electrophoresis production line with an automatic blanking function and its usage method;

[0052] It includes a positioning fixture 37, a column frame 39 and a scrubbing pad 42. Two groups of clamping hand rods 36 are symmetrically installed on the inner side of the fixing plate 35. The positioning fixture 37 is installed at the telescopic end of the clamping hand rod 36. A scrubbing treatment assembly is provided at the top of the upper positioning fixture 37. The scrubbing treatment assembly includes a column frame 39, a scrubbing cylinder 40, a driving lifting plate 41 and a scrubbing pad 42. The column frame 39 is symmetrically installed at the top of the upper positioning fixture 37. The scrubbing cylinder 40 is installed at the top of the column frame 39. The driving lifting plate 41 is installed at the telescopic end of the scrubbing cylinder 40. The scrubbing pad 42 is installed at the bottom end of the driving lifting plate 41. An electrophoresis controller 9 is installed on the front of the electrophoresis production seat 1;

[0053] A micro-arc electrophoresis tank 8 is installed inside the electrophoresis production seat 1.

[0054] The column frames 39 are respectively installed at the tops of the two groups of upper positioning fixtures 37. While providing an installation position for the scrubbing cylinder 40, the column frames 39 ensure the stability of its operation during operation. During the degreasing process of the workpiece by the degreasing liquid in the pretreatment tank 49, the ultrasonic waves generated by the ultrasonic generator 50 enhance the degreasing effect due to vibration. The scrubbing treatment assembly performs auxiliary wiping on the outer side of the upper end of the workpiece. The scrubbing cylinder 40 pushes the driving lifting plate 41 to reciprocate up and down, so that the scrubbing pad 42 continuously contacts the outer side of the upper end of the workpiece. The auxiliary wiping of the scrubbing treatment assembly can further remove the oil stains that are difficult to reach, which can ensure that the surface of the workpiece is cleaner, improve the quality and adhesion of the electrophoresis coating, and avoid problems such as uneven coating, bubbles, and peeling after electrophoresis. The auxiliary wiping of the scrubbing treatment assembly can quickly and effectively remove the oil stains and other impurities on the surface of the workpiece;

[0055] The electrophoresis controller 9 drives and controls the workpiece clamping assembly, the scrubbing treatment assembly, the guide rail 13, the micro-arc electrophoresis tank 8, the pretreatment tank 49, the distance-adjusting hand rod 24 and the dropping hand rod 45 through the electrophoresis driving module and the in-place receiving module. The in-place receiving module receives the output signals of the transmission motor 21 and the clamping hand rod 36 and integrates and controls them through the electrophoresis driving module;

[0056] Pretreatment thoroughly removes impurities such as oil stains, rust, and scale on the surface of the workpiece, ensuring that the surface of the workpiece is clean, free of oil stains and impurities. According to the material of the workpiece and the requirements of electrophoresis, select appropriate pretreatment processes such as degreasing, rust removal, and phosphating. After the impurities are removed, the external crystal supply outer connecting pipe 18 is discharged from the water washing nozzle 17 through the water washing rack 16, and the workpiece after impurity removal is washed with water to ensure that the water washing step is sufficient and effective to avoid the influence of residual impurities on the electrophoresis quality. The workpiece is immersed in the micro-arc electrophoresis tank 8 for electrophoresis coating electrophoresis. During the electrophoresis process, a uniform and dense electrophoresis coating is formed on the basis of the micro-arc oxidation layer by controlling the current of the electrode body 47, the power of the electric heater 48, and the electrolyte.

[0057] Please refer to Figure 1 、 Figure 2 and Figure 4 a micro-arc electrophoresis production line with an automatic blanking function and its usage method;

[0058] It includes a guide rail 13, a unwinding cable 5, and an anti-sway weight 32. A horizontal inclined platform 2 is installed on the top of the electrophoresis production seat 1. The guide rail 13 is installed on the top of the horizontal inclined platform 2, and the guide rail 13 drives the gantry 14. A driving motor 21 is installed on the outside of the support frame 19, and the output end of the driving motor 21 is connected to the outer end of the unwinding guide wheel 20. A weight adding slot 29 is opened on the outside of the unwinding cable 5. An external connection seat 30 is installed on the outside of the unwinding cable 5. A through hole 31 is penetrated through the outside of the external connection seat 30. An anti-sway weight 32 is fitted and installed inside the weight adding slot 29.

A limit bolt 34 is installed through the inside of the through hole 31, and the output end of the limit bolt 34 is in threaded cooperation with the threaded hole 33;

[0059] The horizontal inclined platform 2 supports the guide rail 13. The driving motor 21 runs to drive the unwinding guide wheel 20 to rotate to realize the winding and unwinding of the unwinding cable 5. According to the weight and specifications of the workpiece, select the installation quantity and position of the anti-sway weight 32. Install and engage the anti-sway weight 32 inside the weight adding slot 29. The position of the anti-sway weight 32 in the weight adding slot 29 can be adjusted according to the weight adding requirement. The limit bolt 34 sequentially penetrates through the inside of the through hole 31 and the threaded hole 33 to realize the installation limit of the anti-sway weight 32. The anti-sway weight 32 increases the weight of the unwinding cable 5, effectively reducing the sway and fluctuation generated during the process of the unwinding cable 5 driving the workpiece to move, so that the workpiece maintains a more stable moving state during electrophoresis, which helps to ensure the uniformity and consistency of the workpiece during electrophoresis. The stable moving state can reduce the risk of accidental collision or workpiece detachment caused by swaying, which helps to maintain the continuity during electrophoresis and reduce the pause and adjustment time caused by swaying.

[0062] The unwinding cable 5 passes through the inner side of the drop opening 4, and the weighted position of the unwinding cable 5 is located below the drop opening 4. The guide groove 22 provides a movable space for the push plate 25, and the sink groove 23 provides an installation position for the distance adjustment hand lever 24. The distance adjustment hand lever 24 works to push the push plate 25 to adjust the use position of the guide wheel frame 27. During the unwinding process of the unwinding cable 5, the guide wheel 28 is pressed against and cooperates with the damper 26 to guide it, and the winding and bending direction of the unwinding cable 5 is adjusted to restore it to be flat, so that the internal material of the unwinding cable 5 is evenly stressed, and the damage caused by excessive bending and winding of the unwinding cable 5 on the unwinding guide wheel 20 is avoided, thereby extending the service life of the unwinding cable 5, ensuring the stability of the unwinding cable 5 when pulling and transmitting the workpiece, and further reducing the shaking amplitude when the workpiece moves.

[0063] See also Figure 1 , Figure 6 and Figure 8 , a micro-arc electrophoresis production line with automatic unloading function and its use method;

[0065] The support inclined platform 10 supports the conveyor belt 11 to ensure the working stability of the conveyor belt 11. The side groove 51 provides a moving space for the material retaining flat plate 46. The material retaining flat plate 46 seals the blanking port 43. When the workpiece finishes micro-arc electrophoresis and moves to directly above the conveyor belt 11, the dropping rod 45 works and contracts, causing the material retaining flat plate 46 to retract into the side groove 51, and the blanking port 43 opens.
