Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrophoretic coating technology, and in particular to a workpiece frame for an electrophoretic coating tank. 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 on the surface of a substrate, which is one of the electrodes. Currently, the appearance quality of a product not only reflects its protective and decorative performance, but is also an important factor in the product's value. Therefore, high-efficiency electrophoretic coating is one of the key factors in realizing the value of a product.
[0003] Currently, electrophoretic coating generally involves moving the basket up and down to agitate the electrophoretic solution near the product. However, during this up-and-down movement, the basket often shifts, making it impossible to move it accurately and effectively. This results in uneven coating of the workpiece and affects the coating effect.
[0004] To address this issue, a workpiece frame for electrophoretic coating tanks is proposed, which offers the advantage of uniform coating and thus solves the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a workpiece frame for electrophoretic coating tanks.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece frame for an electrophoretic coating tank, comprising a mounting frame, a lifting rod, and a suspension frame. A connecting sleeve is integrally provided in the middle of the mounting frame, and a lifting rod is inserted inside the connecting sleeve. A first motor is fixed on the top surface of the mounting frame, and a gear is fixed on the output end of the first motor. A rack is welded to the left side wall of the lifting rod, and the rack meshes with the gear at the output end of the first motor. A guide strip is welded to the surface of the lifting rod, and a guide groove is provided on the inner ring of the connecting sleeve corresponding to the guide strip. A fixing box is welded to the bottom of the lifting rod, and a second motor is fixedly installed inside the fixing box. A suspension frame is fixedly installed on the output end of the second motor, and two workpiece placement trays are welded to the lower surface of the suspension frame. A suspension ring is welded to each workpiece placement tray of the suspension frame, and several workpiece hooks are welded to both the inner and outer rings of the suspension ring.
[0007] As a further description of the above technical solution: the surface of the workpiece placement tray is welded with an annular pocket, and the annular pocket is located directly below the suspension ring, and a connecting rod is welded between the annular pocket and the suspension ring. The surface of the workpiece placement tray is provided with several holes, and the annular pocket is made of metal wire mesh.
[0008] As a further description of the above technical solution: a mounting plate is welded to both the left and right ends of the mounting bracket, and screw holes are opened on the surface of the mounting plate.
[0009] As a further description of the above technical solution: a number of guide strips are welded to the surface of the lifting rod, and a number of guide grooves are opened in the inner ring of the connecting sleeve corresponding to the guide strips. Lubricating grease is provided between the guide strips and the guide grooves.
[0010] As a further description of the above technical solution: the suspension frame is composed of a central shaft and two workpiece mounting discs welded to its surface, and the central shaft of the suspension frame is fixedly connected to the output end of the second motor through a coupling.
[0011] As a further description of the above technical solution: a maintenance opening is provided on the outer surface of the fixed box, and a sealing cover is fixedly installed in the maintenance opening by screws.
[0012] This utility model has the following beneficial effects:
[0013] In this invention, a lifting rod is inserted into the connecting sleeve of the mounting frame, and a suspension frame is connected to the bottom of the lifting rod via a fixed box. By starting the first motor on the mounting frame, the first motor drives the gear to rotate in both forward and reverse directions. Since the lifting rod is connected to the gear through a rack and pinion and is slidably connected to the guide groove in the connecting sleeve through several guide bars, the lifting rod can smoothly drive the suspension frame to perform reciprocating lifting and lowering motion. On this basis, by starting the second motor in the fixed box, the suspension frame is driven to rotate in both forward and reverse directions, so that the product on the suspension frame performs forward and reverse rotation motion while reciprocating lifting and lowering. This satisfies the need for agitation of the electrophoretic liquid near the product and facilitates uniform coating of the product.
[0014] In this invention, an annular sump is welded and installed on the workpiece placement tray of the suspension frame, with the annular sump positioned directly below the suspension ring. When the product suspended on the surface of the suspension ring falls off during the electrophoresis stage, the product falls directly into the annular sump. Combined with the hollow structure of the annular sump, this design satisfies the requirement of product suspension and electrophoresis while preventing the product from being difficult to retrieve after it detaches from the workpiece placement tray.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] According to an embodiment of the present invention, a workpiece frame for an electrophoretic coating tank is provided.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, a workpiece frame for an electrophoretic coating tank according to an embodiment of the present invention includes a mounting frame 1, a lifting rod 3, and a suspension frame 10. A connecting sleeve 2 is integrally provided in the middle of the mounting frame 1, and the lifting rod 3 is inserted inside the connecting sleeve 2. A first motor 4 is fixed on the top surface of the mounting frame 1, and a gear 5 is fixed on the output end of the first motor 4. A rack 7 is welded to the left side wall of the lifting rod 3, and the rack 7 meshes with the gear 5 at the output end of the first motor 4. A guide strip 6 is welded to the surface of the lifting rod 3, and a guide groove 15 is opened on the inner ring of the connecting sleeve 2 corresponding to the guide strip 6. A fixing box 8 is welded to the bottom of the lifting rod 3, and a second motor 9 is fixedly installed inside the fixing box 8. The suspension frame 10 is fixedly installed on the output end of the second motor 9, and two workpiece placement trays 11 are welded to the lower surface of the suspension frame 10. A suspension ring 13 is welded to each workpiece placement tray 11 of the suspension frame 10. Both the inner and outer rings are welded with several workpiece hooks 16. In this patent, we only use the first motor 4 and the second motor 9 without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method can be adjusted and operated according to the requirements of their instruction manual, so they will not be described in detail here. The first motor 4 and the second motor 9 are both equipped with their matching control switches. The installation position of the control switches is selected according to the actual use requirements to facilitate the operation and control by the operator. The principle of forward and reverse rotation of the first motor 4 and the second motor 9 is the existing known technology, so its principle will not be explained further. Based on this embodiment, the first motor 4 can also lift the suspension frame 10 through the meshing action of the rack 7 and the gear 5, so that the suspension frame 10 is suspended or immersed in the electrophoresis pool of the electrophoresis equipment, which is convenient for loading and unloading products.
[0023] In one embodiment, an annular sac 12 is welded to the surface of the workpiece placement tray 11, and the annular sac 12 is located directly below the suspension ring 13. A connecting rod is welded between the annular sac 12 and the suspension ring 13. The surface of the workpiece placement tray 11 has several holes. The annular sac 12 is made of metal wire mesh. With this structure, when the product suspended on the surface of the suspension ring 13 falls off during the electrophoresis stage, the product falls directly into the annular sac 12, avoiding the situation where the product is difficult to collect after it leaves the workpiece placement tray 11.
[0024] In one embodiment, a mounting plate 14 is welded to both the left and right ends of the mounting frame 1, and screw holes are provided on the surface of the mounting plate 14. The mounting plate 14 and screw holes facilitate the installation of the mounting frame 1 (the length of the mounting frame 1 is adapted to the housing space of the electrophoresis equipment).
[0025] In one embodiment, a number of guide strips 6 are welded to the surface of the lifting rod 3, and a number of guide grooves 15 are opened on the inner ring of the connecting sleeve 2 corresponding to the guide strips 6. Lubricating grease is provided between the guide strips 6 and the guide grooves 15. By setting the guide strips 6 and the guide grooves 15, the smoothness of the lifting motion of the lifting rod 3 can be easily increased.
[0026] In one embodiment, the suspension frame 10 consists of a central shaft and two workpiece mounting discs 11 welded to its surface. The central shaft of the suspension frame 10 is fixedly connected to the output end of the second motor 9 via a coupling. The central shaft of the suspension frame 10 facilitates the connection between the suspension frame 10 and the second motor 9.
[0027] In one embodiment, a maintenance opening is provided on the outer surface of the fixed box 8, and a sealing cover is fixedly installed in the maintenance opening by screws. The maintenance opening and the sealing cover facilitate the installation, removal and maintenance of the second motor 9.
[0028] Working principle:
[0029] In use, the mounting frame 1 is first fixed in the electrophoresis equipment, and the suspension frame 10 is suspended or immersed in the electrophoresis pool of the electrophoresis equipment. Before electrophoresis, the product is hung on the suspension ring 13 of the suspension frame 10. By starting the first motor 4 on the mounting frame 1, the first motor 4 drives the gear 5 to rotate in both forward and reverse directions. Since the lifting rod 3 is connected to the gear 5 through the rack 7 and the lifting rod 3 is slidably connected to the guide groove 15 in the connecting sleeve 2 through several guide bars 6, the lifting rod 3 can smoothly drive the suspension frame 10 to perform reciprocating lifting and lowering movements. On this basis, by starting the second motor 9 in the fixed box 8, the suspension frame 10 is driven to rotate in both forward and reverse directions, so that the product on the suspension frame 10 performs forward and reverse rotation movements while reciprocating lifting and lowering. This satisfies the agitation of the electrophoresis liquid near the product and facilitates uniform coating of the product. When the product suspended on the surface of the suspension ring 13 falls off during the electrophoresis stage, the product falls directly into the annular hopper 12, avoiding the situation where the product is difficult to retrieve after falling off the workpiece placement tray 11.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
