[0003] Chinese Patent Announcement No. CN222226625U discloses an electrophoretic coating conveying device for automotive parts. This patent conveys automotive parts via a hanging rail and a sliding plate. When the automotive parts need to be rotated for adjustment, the drive motor drives the drive gear to rotate. The drive gear, through meshing with the driven gear, synchronously drives the vertical rod to rotate, thereby causing the housing to rotate the joint components that are attached to the surface of the hook ring and the hanging assembly. This allows the automotive joint components to rotate during electrophoretic coating, avoiding dead angles during the electrophoretic coating process.

[0004] In existing technologies, different types of automotive parts require matching tooling boxes for electrophoretic coating and conveying. However, existing tooling boxes rely on screwdrivers for disassembly and assembly, which makes the operation complex and cumbersome, increases changeover time and the risk of human error, and affects the overall efficiency of the production line.

[0005] Based on this, this utility model designs an electrophoretic coating conveying equipment for automotive parts with quick tooling switching to solve the above problems. Utility Model Content

[0009] Furthermore, the assembly / disassembly assembly includes a positioning groove inside the locking block, a moving groove inside the mounting block, a protrusion inside the positioning groove, and a moving rod fixedly connected to the side of the protrusion.

[0010] Furthermore, the movable rod is inserted into the outer surface of the mounting block and fixedly connected to a circular plate.

[0011] Furthermore, a spring is sleeved on the outer surface of the moving rod, with one end of the spring connected to the side of the protrusion and the other end connected to the inner cavity of the moving groove.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 An electrophoretic coating conveying equipment for automotive parts with quick tooling switching includes a conveying track 1, a conveying mechanism 102 slidably connected to the outer surface of the conveying track 1, a traction rope 1021 fixedly connected to the lower part of the conveying mechanism 102, and a disassembly and assembly component 2 installed at one end of the traction rope 1021.

[0024] In this embodiment of the utility model, the disassembly and assembly component 2 includes an installation block 103 fixedly connected to one end of the traction rope 1021. The installation block 103 has a slot 202 inside, and a locking block 201 is locked inside the slot 202. One end of the locking block 201 is fixedly connected to a tooling box 101. The disassembly and assembly component 2 includes a positioning groove 205 opened inside the locking block 201. The installation block 103 has a moving groove inside. A protrusion 206 is locked inside the positioning groove 205. A moving rod 207 is fixedly connected to the side of the protrusion 206. A circular plate is fixedly connected to the moving rod 207 through the outer surface of the installation block 103. A spring 208 is sleeved and connected to the outer surface of the moving rod 207. One end of the spring 208 is connected to the side of the protrusion 206, and the other end is connected to the inner cavity of the moving groove. A baffle 5 is fixedly connected to the outer surface of the tooling box 101. A door panel 4 is rotatably connected to the outer surface of the tooling box 101 via a hinge. A handle is fixedly connected to the outer surface of the door panel 4.

[0025] In one embodiment of this utility model, the locking block 201 on the tooling box 101 is aligned with the locking groove 202 in the mounting block 103 and locked in place. As the locking block 201 goes deeper into the locking groove 202, the locking block 201 pushes the protrusion 206 to move into the moving groove, causing the moving rod 207 and the spring 208 to compress. When the locking block 201 is fully locked in place, the spring 208 rebounds and makes the protrusion 206 lock in the positioning groove 205 inside the locking block 201. Otherwise, it can be quickly disassembled, thereby realizing the automatic locking and precise positioning of the tooling box 101 and the conveying mechanism 102.

[0026] In some embodiments, such as Figure 1-5 As shown, in a preferred embodiment of the present invention, a drying component 3 is installed on the outer surface of the disassembly and assembly component 2.

[0027] In this embodiment of the present invention, the drying assembly 3 includes air compressors 301 symmetrically connected to the outer surface of the tooling box 101. The inner cavities of the two air compressors 301 are connected to conveying pipes 302. The outer surface of the tooling box 101 is fixedly connected to two heating chambers 304. The inner cavities of the two heating chambers 304 are connected to hot air pipes 306. The outer surface of the hot air pipes 306 is fixedly connected to multiple spray guns 303. The outer surface of the heating chambers 304 is fixedly connected to a heat insulation layer. The outer surface of the hot air pipes 306 is fixedly connected to a support block 6. The upper surface of the support block 6 is connected to the top wall of the inner cavity of the tooling box 101. The interior of the heating chambers 304 is fixedly connected to multiple electric heating wires 305. The inner cavity of the heating chambers 304 is fixedly connected to a temperature sensor. One end of the conveying pipe 302 is connected to the inner cavity of the heating chambers 304. The outer surfaces of the conveying pipes 302 and the hot air pipes 306 are both fixedly connected to pumps.

[0028] In one embodiment of this utility model, after installation, the conveying mechanism 102 slides on the conveying track 1. During this process, the air compressor 301 is started to generate high-pressure gas, which is then pumped into the conveying pipe 302 and into the heating chamber 304. The gas is heated by the electric heating wire 305. When it is necessary to dry the automotive parts in the tooling box 101, the surface pump of the hot air pipe 306 is immediately started to pump the hot air in the heating chamber 304 into multiple spray guns 303 through the hot air pipe 306, so that the spray guns 303 spray out the hot air, thereby achieving uniform hot air spray drying on the surface of the workpiece.

[0029] The working principle of this utility model is as follows: When it is necessary to replace the tooling box 101 suitable for different types of automotive parts, the operator installs the pre-installed tooling into the tooling box 101, then aligns the locking block 201 on the tooling box 101 with the locking groove 202 in the mounting block 103 and engages it. As the locking block 201 goes deeper into the locking groove 202, the locking block 201 will push the protrusion 206 to move into the moving groove, driving the moving rod 207 and the spring 208 to compress. When the locking block 201 is fully engaged, the spring 208 rebounds, causing the protrusion 206 to engage with the positioning groove 205 inside the locking block 201. At the same time, the magnetic block 1 203 and the magnetic block 204 are connected by magnetism to further strengthen the connection. Conversely, they can be quickly disassembled, thereby realizing the automatic locking and precise positioning of the tooling box 101 and the conveying mechanism 102. The whole process does not require the use of screwdrivers or other tools, which significantly improves the speed of replacement and the convenience of operation.

[0030] After installation, the conveying mechanism 102 slides on the conveying track 1, and the tooling box 101 is driven into each process (such as pretreatment, electrophoresis, post-rinsing, etc.) by the traction rope 1021. During this process, the power supply and controller of the two air compressors 301, the electric heating wire 305 and the surface pump of the conveying pipe 302 are started, so that the air compressor 301 generates high-pressure gas, which is then pumped into the conveying pipe 302 and then into the heating chamber 304. The gas is heated by the electric heating wire 305. At the same time, the temperature sensor monitors the temperature in the heating chamber 304 in real time to ensure that it is within the preset value.

[0031] When it is necessary to dry the automotive parts in the tooling box 101, the power supply and controller of the surface pump of the hot air duct 306 are immediately turned on, so that the pump delivers the hot air in the heating chamber 304 through the hot air duct 306 to multiple spray guns 303, so that the spray guns 303 spray out the hot air, thereby achieving uniform hot air spray drying on the surface of the workpiece. The heat loss is effectively reduced by the heat insulation layer, and the support block 6 enhances the stability of the hot air duct 306 and prevents it from falling off due to vibration. At the same time, the cooperation between the door panel 4 and the baffle 5 can prevent a small amount of hot air from overflowing, ensuring operational safety and environmental cleanliness.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
