Description

Technical Field

[0001] This utility model is a degreasing device for automotive parts before electrophoresis, belonging to the field of automotive parts processing. Background Technology

[0002] In the pretreatment process of electrophoretic coating for automotive parts, degreasing is a crucial step to ensure a tight bond between the electrophoretic layer and the part surface, thereby improving coating quality. Ultrasonic cleaning machines, with their highly efficient degreasing and cleaning capabilities, have become a commonly used core piece of equipment in this stage. The operating logic involves neatly placing multiple automotive parts to be treated in a dedicated mesh frame, then smoothly lowering the frame into the cleaning tank of the ultrasonic cleaning machine. Utilizing the cavitation effect generated by the ultrasonic waves, oil, debris, and other impurities adhering to the part surface are removed, laying a clean surface foundation for the subsequent electrophoretic coating process.

[0003] The wire mesh frame itself has a certain weight, and with the addition of a considerable number of metal parts, the overall weight is quite substantial. In actual production, the transfer of the wire mesh frame at the ultrasonic cleaning machine station (including transferring it from the conveyor line to the cleaning tank, and removing it from the tank after cleaning and transferring it to the next process) is mostly done manually. Operators need to use simple tools or move it by hand, not only overcoming the heavy load of the wire mesh frame but also ensuring its stability during the transfer process to prevent parts from falling or the wire mesh frame from bumping into the cleaning tank. Long-term repetitive handling work will significantly increase the labor intensity of personnel and easily lead to physical strain injuries; at the same time, the efficiency of manual transfer is limited, and if the batch of parts is large, it will also cause slowdowns in the station's flow, affecting the overall cycle time of the electrophoretic pretreatment process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an oil removal device for automotive parts before electrophoresis, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-electrophoretic degreasing device for automotive parts, comprising:

[0006] An ultrasonic cleaner with a liquid collection tank installed on one side;

[0007] The lifting base is connected to the ultrasonic cleaner via a lifting component. The lower end of the lifting base is equipped with a bracket for supporting the mesh frame, and the bracket extends into the cleaning tank of the ultrasonic cleaner.

[0008] The first frame is installed on the side of the upper surface of the ultrasonic cleaner away from the liquid collection tank, and multiple first rollers for supporting the mesh frame are rotatably installed inside the first frame.

[0009] The second frame is installed on the top of the liquid collection tank, and multiple second rollers for supporting the mesh frame are rotatably installed inside the second frame.

[0010] The transfer component, in conjunction with the first and second idlers, is used to transfer the position of the mesh frame containing automotive parts.

[0011] Furthermore, the lifting component includes a back frame, which is installed on the upper part of the back of the ultrasonic cleaner. A vertically arranged hydraulic cylinder is installed on the upper end of the back frame, and a connecting seat is installed on the movable end of the hydraulic cylinder. The connecting seat is connected to the lifting seat. Two vertically arranged elongated openings are opened on one side of the back frame, and the connection part between the connecting seat and the lifting seat passes through the elongated openings.

[0012] Furthermore, a guide rod is provided on the side of the connecting seat away from the lifting seat. Both ends of the guide rod are connected to the back frame. A sliding sleeve is fitted on the guide rod, and the sliding sleeve is connected to the connecting seat by screws.

[0013] Furthermore, the transfer component includes a movable frame, in which multiple third rollers are rotatably mounted. A base is provided on the lower side of the movable frame, and universal wheels are installed at the four corners of the lower surface of the base. Four evenly arranged support legs are installed between the base and the movable frame. The third rollers, second rollers, and first rollers are of equal height.

[0014] Furthermore, both the side of the ultrasonic cleaner facing away from the liquid collection tank and the side of the liquid collection tank facing away from the ultrasonic cleaner are equipped with L-shaped plates. Two clamping plates are installed at one end of the L-shaped plate, and one of the support legs is inserted between the two clamping plates. The support leg is connected to the structure formed by the L-shaped plate and the two clamping plates through a positioning pin.

[0015] Furthermore, the L-shaped plate has a first pin hole on the side facing the clamping plate, the clamping plate has a second pin hole aligned with the first pin hole on one side, the support leg has a third pin hole on one side, and the positioning pin passes through the channel formed by the first pin hole, the second pin hole, and the third pin hole.

[0016] Furthermore, a sleeve is provided on the side of the first pin hole away from the clamping plate. One end of the sleeve is connected and fixed to the L-shaped plate. A rubber sleeve is glued inside the sleeve. The positioning pin passes through the rubber sleeve, and the diameter of the positioning pin is equal to the inner diameter of the rubber sleeve.

[0017] Furthermore, guide plates are installed at the ends of the two clamping plates that are away from the L-shaped plate, and the two guide plates form a triangular structure.

[0018] Furthermore, a first stiffener and a second stiffener are installed on both the side of the ultrasonic cleaner facing away from the liquid collection tank and the side of the liquid collection tank facing away from the ultrasonic cleaner. The first stiffener and the second stiffener are connected and fixed together, and the first stiffener and the second stiffener are arranged perpendicular to each other.

The mesh frame can be transferred between the roller conveyor surface formed by multiple third idlers, the roller conveyor surface formed by multiple first idlers, the roller conveyor surface formed by multiple second idlers, and the bracket, realizing easy transfer from the feeding end to the cleaning tank and then to the collection tank. There is no need for manual handling at each station, which greatly shortens the flow time of the mesh frame containing automotive parts between processes and improves the overall process cycle of degreasing before electrophoresis. The hydraulic cylinder drives the lifting seat and bracket to lift and lower, which can smoothly lower the mesh frame loaded with automotive parts into the cleaning tank of the ultrasonic cleaner. After cleaning, the mesh frame can be lifted again, eliminating the need for manual handling or the use of simple tools to move heavy mesh frames, reducing the labor intensity of operators and avoiding limb injuries caused by long-term handling.

A bracket 37 for lifting the mesh frame is installed at the lower end of the lifting seat 3. The bracket 37 extends into the cleaning tank of the ultrasonic cleaner 1. The hydraulic cylinder 32 drives the lifting seat 3 and the bracket 37 to lift and lower, so that the mesh frame loaded with automotive parts can be smoothly lowered into the cleaning tank of the ultrasonic cleaner 1. After cleaning, the mesh frame can be lifted again.

[0038] See Figure 1 , Figure 3 and Figure 4 The first frame 2 is installed on the upper surface of the ultrasonic cleaner 1 on the side away from the liquid collection tank 11. Multiple first rollers 21 for supporting the mesh frame are rotatably installed inside the first frame 2. The second frame 4 is installed on the top of the liquid collection tank 11. Multiple second rollers 41 for supporting the mesh frame are rotatably installed inside the second frame 4. Multiple third rollers 51 are rotatably installed inside the movable frame 5. A base 54 is provided on the lower side of the movable frame 5. Universal wheels 55 are installed at the four corners of the lower surface of the base 54. Four evenly arranged support legs 52 are installed between the base 54 and the movable frame 5. The heights of the third rollers 51, the second rollers 41 and the first rollers 21 are equal. The first idler roller 21, the second idler roller 41, and the third idler roller 51 are at the same height, forming a continuous roller conveyor surface. The mesh frame can be transferred between the roller conveyor surface formed by multiple third idler rollers 51, the roller conveyor surface formed by multiple first idler rollers 21, the roller conveyor surface formed by multiple second idler rollers 41, and the bracket 37, realizing easy transfer from the feeding end to the cleaning tank and then to the collection tank 11. There is no need for manual handling at each station, which greatly shortens the flow time of the mesh frame storing automotive parts between processes, improves the overall process rhythm of degreasing before electrophoresis, and eliminates the need for manual handling of heavy mesh frames by hand or with the help of simple tools, reducing the labor intensity of operators and avoiding limb injuries caused by long-term handling.

[0039] See Figures 1-3 , Figure 5 An L-shaped plate 6 is installed on both the side of the ultrasonic cleaner 1 away from the liquid collection tank 11 and the side of the liquid collection tank 11 away from the ultrasonic cleaner 1. A first stiffener 64 and a second stiffener 65 are installed on both the side of the ultrasonic cleaner 1 away from the liquid collection tank 11 and the side of the liquid collection tank 11 away from the ultrasonic cleaner 1. The first stiffener 64 and the second stiffener 65 are connected and fixed. The first stiffener 64 and the second stiffener 65 are arranged perpendicular to each other. The first stiffener 64 is connected and fixed to the part of the L-shaped plate 6 near the clamping plate 62.

A first pin hole 66 is opened on the side of the L-shaped plate 6 facing the clamping plate 62. A second pin hole 67 is opened on one side of the clamping plate 62, which is aligned with the first pin hole 66. A third pin hole 53 is opened on one side of the support leg 52. A positioning pin 61 passes through the channel formed by the first pin hole 66, the second pin hole 67 and the third pin hole 53. The support leg 52 is connected to the structure formed by the L-shaped plate 6 and the two clamping plates 62 through the positioning pin 61, which can prevent the displacement of the roller conveyor surface formed by multiple third idlers 51 when transferring the wire mesh frame.

[0041] A sleeve 7 is provided on the side of the first pin hole 66 away from the clamping plate 62. One end of the sleeve 7 is connected and fixed to the L-shaped plate 6. A rubber sleeve 71 is glued inside the sleeve 7. The diameter of the positioning pin 61 is equal to the inner diameter of the rubber sleeve 71. After the positioning pin 61 passes through the rubber sleeve 71, it can increase the friction between the sleeve 7 and the positioning pin 61 and prevent the positioning pin 61 from moving randomly.
