Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, and in particular to a flip-up hanger for electrophoretic coating. Background Technology

[0002] Electrophoretic coating is a coating method that uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit onto the surface of a substrate, which is one of the electrodes. During electrophoretic coating, the workpiece needs to be completely immersed in the electrophoretic solution. The workpiece is usually hung on a fixture and lowered into the electrophoretic solution tank by the fixture. When the workpiece is immersed in the electrophoretic solution, there may be uncoated areas on the workpiece surface, leading to workpiece quality problems and economic losses. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a flip-up fixture for electrophoretic coating, which can automatically flip the workpiece to ensure the quality of electrophoretic coating.

[0004] Therefore, the technical solution of this utility model is: a flip-up hanger for electrophoretic coating, including a hanger bracket, two workpiece mounting frames inside the hanger bracket, and multiple mounting positions on the workpiece mounting frames; the two ends of the workpiece mounting frames are rotatably mounted on the hanger bracket via rotating shafts, and a gear is mounted on one side of the rotating shaft; the hanger bracket has longitudinal sliding grooves on both sides, with the gear placed in the middle of the sliding groove; a floating component is provided below the hanger bracket, with connecting rods on both sides of the floating component, the connecting rods extending into the sliding grooves and slidingly engaging with the sliding grooves; the connecting rods have toothed structures that mesh with the gears; the floating component can drive the workpiece mounting frames to rotate relative to the hanger bracket via the gears.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the connecting rod has an opening in the middle, and two toothed structures are provided on the side of the opening, which mesh with the gears on the sides of the two workpiece mounting brackets.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the workpiece mounting frame includes a fixed frame and an adjusting frame. The fixed frame is rotatably mounted on the hanger bracket at both ends. The fixed frame is provided with a long slot hole, and the adjusting frame is provided with a mounting hole. The adjusting bolt passes through the mounting hole and the long slot hole to fix the adjusting frame and the fixed frame together.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the workpiece mounting frame has two mounting positions, and each mounting position has a positioning column at the upper and lower ends. The upper positioning column is set on the fixed frame, and the lower positioning column is set on the adjusting frame.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the floating component is a cylindrical float structure, which is installed below the hanger bracket.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the hanger bracket is provided with two workpiece mounting brackets arranged side by side, and the rotation of the two workpiece mounting brackets is controlled by the toothed structure on the connecting rod.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a hook is provided above the hanging bracket.

[0011] In use, the workpiece is placed on the mounting position, and the adjusting frame can be adjusted in the long slot of the fixed frame to accommodate workpieces of more sizes. Then, the hanger bracket is hung on the upper conveyor line. After the previous process, the hanger bracket moves with the conveyor line, bringing the workpiece to the top of the electrophoresis tank and gradually causing it to sink. When the float under the hanger bracket comes into contact with the liquid surface, the float is lifted by buoyancy, causing the connecting rod to move upward. When the toothed structure passes through the gear, it drives the gear to rotate, thereby driving the workpiece mounting frame to rotate around the hanger bracket. The workpiece is immersed in the electrophoresis liquid for thorough electrophoretic coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The workpiece mounting bracket is rotated and installed on the hanger bracket, and a float is set below the hanger bracket. When the hanger bracket is immersed in the electrophoretic solution, the buoyancy of the float can move it upward, and drive the gear to rotate through the tooth structure of the connecting rod, thereby causing the workpiece to flip in the electrophoretic solution, ensuring the quality of electrophoretic coating and improving the coating efficiency of the workpiece.

[0014] 2. The workpiece mounting bracket is designed with separate fixing components and adjustment brackets. The distance between the two can be adjusted through long slots, so that the workpiece mounting bracket can fix workpieces of different specifications more securely and with strong versatility.

[0015] 3. Each hanger bracket can be equipped with two workpiece mounting racks, and each workpiece mounting rack can be equipped with two mounting positions, so that four workpieces can be installed on a single hanger bracket at the same time, which greatly improves the efficiency of electrophoretic coating and saves the cost of hangers.

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0024] See the attached drawings. The flip-up hanger for electrophoretic coating described in this embodiment includes a hanger bracket 1 with a hook 2 on top for easy mounting of the hanger bracket 1 onto a conveyor line, allowing it to move through various processes. The hanger bracket 1 has a rectangular frame structure and contains two workpiece mounting racks 3 arranged side-by-side.

[0025] The workpiece mounting frame 3 includes a fixed frame 31 and an adjusting frame 32. The fixed frame 31 is in the shape of an inverted U-shape, with rotating shafts at both ends. The hanger bracket 1 has through holes on both sides, and bearings can be installed in the through holes, so that the two ends of the fixed frame 31 can be rotatably mounted in the through holes. A gear 33 is installed on the rotating shaft on one side of the workpiece mounting frame. The fixed frame 31 has a first connecting rod 311 in the middle, and the first connecting rod 311 has a long slot 312. The first connecting rod 311 is divided into two mounting positions on both sides. The fixed frame 31 has a downward-facing upper positioning post 313.

[0026] The adjusting frame 32 has a second connecting rod 321 in the middle, and the second connecting rod 321 has a mounting hole. The mounting hole is positioned opposite to the elongated slot 312. The adjusting bolt 4 passes through the mounting hole and the elongated slot, and the position of the adjusting frame 32 can be adjusted up and down according to the elongated slot. Finally, the adjusting bolt is tightened to fix the adjusting frame 32 to the fixing frame 31. The adjusting frame 32 has lower positioning posts 322 on both sides, which cooperate with the upper positioning posts 313 on the fixing frame 31 to fix the workpiece 5.

[0027] The hanger bracket 1 has longitudinal grooves 11 on both sides, with gears 33 positioned in the middle of the grooves 11. A floating component 6 is located below the hanger bracket 1, with connecting rods 61 on both sides of the floating component 6. The connecting rods 61 extend into the grooves 11 and slide in cooperation with them. An opening is located in the middle of the connecting rod 61, and two toothed structures 62 are located on the sides of the opening, meshing with the gears 33 on the sides of the two workpiece mounting brackets 3. The floating component 6 can be a cylindrical float structure. After contacting the liquid surface, the floating component experiences buoyancy and moves upwards. The engagement of the toothed structures 62 on the connecting rods with the gears 33 causes the workpiece mounting brackets 3 to rotate relative to the hanger bracket 1.

[0028] In use, the workpiece 5 is placed on the mounting position of the workpiece mounting bracket 3. The adjusting bracket 32 ​​can be adjusted in the long slot of the fixed bracket 31 to accommodate workpieces of more sizes. Then, the hanger bracket 1 is hung on the upper conveyor line. After the previous process, the hanger bracket 1 moves with the conveyor line, bringing the workpiece to the top of the electrophoresis tank 6 and gradually causing the workpiece 5 to sink. When the floating part 6 on the hanger bracket 1 is in contact with the liquid surface for a period of time, the floating part 6 is buoyed and moves upward, causing the connecting rod 61 to move upward along the slide. During the upward movement, the toothed structure 62 drives the gear 33 to rotate, thereby driving the workpiece mounting bracket 3 to rotate the workpiece 5 around the hanger bracket 1. After the floating part 6 has completely sunk, it is buoyed and maintains the maximum state. The workpiece is in a flipped state and fully electrophoretic coating is carried out in the electrophoresis liquid.

[0029] After the electrophoretic coating is completed, the hanger bracket 1 moves upward with the conveyor line, bringing out the workpiece 5. Under the action of the floating part 6 and the workpiece's own weight, the float moves downward, and the toothed structure on the connecting rod passes through the gear, causing the workpiece mounting bracket 3 to reset.
