Description

Technical Field

[0001] This utility model belongs to the field of electrophoretic coating technology for automotive parts, and more specifically, it relates to an electrophoretic coating tank for automotive parts. Background Technology

[0002] Electrophoretic coating technology, with its advantages of uniform coating and strong adhesion, is widely used in the surface treatment of automotive parts. The electrophoresis tank, as the core equipment of this process, directly affects coating quality and production efficiency due to its structural rationality. Existing electrophoretic coating tanks for automotive parts mainly consist of a tank body, pipe interfaces, and a stirring mechanism. The pipe interfaces connect to external pipes to achieve water inlet, outlet, and drainage operations. The stirring mechanism drives the agitator blades to maintain the uniformity of the electrophoretic solution inside the tank, thereby ensuring more uniform electrophoresis on automotive parts.

[0003] Existing application number CN202121913394.1 discloses an electrophoresis tank device for electrophoretic coating of automotive parts, including an electrophoresis tank body. A working tank is arranged on the left side inside the electrophoresis tank body, and a partition block is arranged on the right side of the working tank. A motor is fixedly connected to the bottom of the partition block, and a first gear is fixedly connected to the middle of the bottom end of the motor. A second gear is meshed with the right side of the first gear, and the second gear is fixedly connected to the lower part of the outer circumference of a first rotating shaft. A second stirring blade is fixedly connected to the top of the first rotating shaft through the partition plate. In this utility model, through the combination of these components, the motor can drive the first gear, which in turn drives the first and second rotating shafts to rotate via the second and third gears. This causes the first and second stirring blades to rotate, preventing the electrophoretic solution inside the device from condensing. This is beneficial for industrial production, indirectly improving production efficiency, and is worthy of widespread promotion.

[0004] Based on the above, existing electrophoretic coating tanks for automotive parts require frequent maintenance. When checking for leaks at pipe joints or sedimentation within the tank, maintenance personnel often carry wrenches, gloves, and other tools. Because of their convenience, these tools are frequently placed on the side of the tank. However, tools placed on the side are easily affected by external factors and fall into the tank, interfering with the electrophoresis effect. Furthermore, during the electrophoresis process, the conveying mechanism continuously feeds parts into the tank via hooks. Some hooks may simultaneously suspend multiple sets of parts. If one or two sets of parts become misaligned or even fall off, it will cause the hooks to tilt, leading to the overall tilting of the parts. This not only increases the risk of parts falling off but also poses a risk of collision with the tank edge or subsequent machinery, causing scratches and damage. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an electrophoresis tank for automotive parts electrophoretic coating. This addresses the issues of existing electrophoresis tanks for automotive parts, which require frequent maintenance. When inspecting for leaks at pipe joints or sedimentation within the tank, maintenance personnel often carry wrenches, gloves, and other tools, frequently placing them on the side of the tank for ease of operation. However, tools placed on the side are easily affected by external factors and fall into the tank, interfering with the electrophoresis effect. Furthermore, during parts electrophoresis, the conveying mechanism continuously feeds parts into the tank via hooks. Some hooks may simultaneously suspend multiple sets of parts. If one or two sets of parts become misaligned or even fall off, it can cause the hooks to tilt, leading to the overall tilting of the parts. This not only increases the risk of parts falling off but also potentially causing them to collide with the tank edge or subsequent machinery, resulting in scratches and damage.

[0006] The purpose and effect of this utility model's electrophoretic coating tank for automotive parts are achieved through the following specific technical means:

[0007] An electrophoretic coating tank for automotive parts includes a main body, inclined sides, a drive mechanism, a transmission frame, a smoothing plate, maintenance components, and a detection component. The inclined sides are located on the front and rear sides of the main body. Four sets of drive mechanisms are fixedly installed on the left and right sides of the main body. Two sets of transmission frames are located on the left and right sides of the main body. Two sets of smoothing plates are hinged to the tops of the two sets of transmission frames. The maintenance components are located on the front and rear sides of the main body. The detection component is located on the left and right sides of the main body.

[0008] Furthermore, the maintenance component includes: a limiting stop and a through groove. The limiting stop is fixedly installed at the bottom of the inclined side, and the limiting stop and the inclined side form a 90-degree angle. Multiple sets of through grooves are provided, and multiple sets of through grooves are opened inside the limiting stop.

[0009] Furthermore, the detection component includes: a rotating threaded cylinder and a threaded screw. There are four sets of rotating threaded cylinders, which are rotatably connected to the left and right sides of the electrophoresis tank body. The four sets of rotating threaded cylinders are respectively fixedly installed inside the four sets of drive mechanisms. There are four sets of threaded screws, which are threadedly connected to the inside of the four sets of rotating threaded cylinders. Every two sets of threaded screws are fixedly connected to the bottom of a transmission frame.

[0010] Furthermore, the detection component also includes: a hinge shaft and an elastic torsion spring. The hinge shaft is provided in two sets, which are respectively fixedly connected inside the two sets of smooth plates and respectively rotatably connected to the top of the two sets of transmission frames. The elastic torsion spring is provided in two pairs, with one end of the two pairs of elastic torsion springs respectively fixedly connected inside the two sets of transmission frames and the other end of the two pairs of elastic torsion springs respectively fixedly connected to both ends of the two sets of hinge shafts.

[0011] Furthermore, the detection component also includes: a limit rod and a trigger switch. The limit rod is provided in two sets, and the two sets of limit rods are respectively fixedly connected to one end of two sets of hinge shafts. The trigger switch is provided in two sets, and the two sets of trigger switches are fixedly installed inside the transmission frame. The two sets of trigger switches are respectively located at the bottom of the two sets of limit rods.

[0012] Furthermore, the detection component also includes: a warning mechanism, a speaker, and an indicator light. The warning mechanism is provided in two sets, and the two sets of warning mechanisms are respectively fixedly installed on the front side of the two sets of transmission frames. The speaker is provided in two sets, and the two sets of speakers are respectively fixedly installed inside the two sets of warning mechanisms.

[0013] Furthermore, the detection component also includes a collection slot, wherein two sets of collection slots are provided, and the two sets of collection slots are respectively engaged inside two sets of transmission frames.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this utility model has a maintenance component. By setting outwardly inclined slopes on the front and rear sides of the electrophoresis tank body, and combining them with vertical limiting bars at the bottom, it can reduce the situation where workers casually place tools on the side of the tank body, and also prevent tools from sliding into the tank by using the slope angle, thus avoiding tools falling in and interfering with the electrophoresis effect. At the same time, multiple sets of through grooves on the limiting bars can guide small impurities to slide down naturally, preventing impurities from accumulating in the receiving space, reducing the maintenance and cleaning burden, and ensuring the stable operation of the electrophoresis tank.

[0016] Secondly, this invention features a detection component. An elastic torsion spring keeps a smooth plate at a specific angle, aligning it with the lowest point of the component to be electrophoretically coated. When the hook shifts or the component tilts and droops, the component pushes the smooth plate to swing, triggering a limit rod that activates a switch. This activates a speaker and indicator light, promptly alerting staff to prevent the component from falling or impacting the tank, causing damage to subsequent machinery. Furthermore, the inclined surface and smoothness of the smooth plate guide the dripping liquid after electrophoresis into a collection tank, concentrating the electrophoretic solution and reducing contamination. Additionally, a drive mechanism rotates a threaded cylinder, and the threaded transmission raises and lowers the threaded screw, adjusting the height of the transmission frame to accommodate components of different heights, thus improving the equipment's versatility.

[0017] This utility model has the advantages of easy maintenance, prevention of parts falling off, and high applicability. It can reduce the risk of tools entering the tank and the cost of cleaning impurities through maintenance components, and ensure the stability of the electrophoresis process. It can also achieve real-time early warning of part displacement by relying on detection components. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides an electrophoresis tank for electrophoretic coating of automotive parts, including an electrophoresis tank body 1, inclined sides 2, drive mechanisms 3, transmission frames 4, smooth plates 5, and maintenance components.

At the same time, the inclined design of the inclined edge 2 can reduce the retention of larger dust and impurities, and together with the multiple sets of through grooves 202 on the limiting baffle 201, it can guide small impurities to slide down naturally, avoiding accumulation in the receiving space.

[0032] Example 2:

[0033] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: a detection component, which is set on the left and right sides of the electrophoresis tank body 1.

[0034] The detection components include: rotating threaded cylinders 301 and threaded screws 302. There are four sets of rotating threaded cylinders 301, which are rotatably connected to the left and right sides of the electrophoresis tank body 1. The four sets of rotating threaded cylinders 301 are respectively fixedly installed inside the four sets of drive mechanisms 3. There are four sets of threaded screws 302, which are threadedly connected to the four sets of rotating threaded cylinders 301. Every two sets of threaded screws 302 are fixedly connected to the bottom of a transmission frame 4.

[0035] The detection assembly also includes: a hinge shaft 501 and an elastic torsion spring 502. Two sets of hinge shafts 501 are provided, and the two sets of hinge shafts 501 are fixedly connected inside the two sets of smooth plates 5 respectively.

One end of the two pairs of elastic torsion springs 502 is fixedly connected inside the two sets of transmission frames 4 respectively, and the other end of the two pairs of elastic torsion springs 502 is fixedly connected to both ends of the two sets of hinge shafts 501 respectively.

The two sets of trigger switches 401 are respectively located at the bottom of the two sets of limit rods 503.

[0037] The detection component also includes: a warning mechanism 402, a speaker 403, and an indicator light 404. Two sets of warning mechanisms 402 are provided, and the two sets of warning mechanisms 402 are fixedly installed on the front side of the two sets of transmission frames 4 respectively.

[0038] The detection component also includes a collection trough 405, which is provided in two sets, and the two sets of collection troughs 405 are respectively snapped into the two sets of transmission frames 4.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When the conveying mechanism transports automotive parts for electrophoresis via hooks, the transmission frame 4 is located on both sides of the electrophoresis tank body 1. The elastic torsion spring 502, under the action of elastic force, drives the smooth plate 5 to swing. The limiting rod 503 limits its swing position. When the limiting rod 503 is horizontal with the top surface of the transmission frame 4, the smooth plate 5 forms a 45° angle, and its highest point is flush with the lowest point of the part to be electrophoresed. If the hooks shift or parts fall off, causing the parts to tilt and droop, its lowest position changes. When passing the smooth plate 5, it will push the smooth plate 5 to swing around the hinge shaft 501, thereby causing the hinge shaft 501 to rotate and the elastic torsion spring 502 to contract. Simultaneously, the hinge shaft 501 drives the limiting rod 503 to swing, triggering the trigger switch 401 below, activating the switching circuit, causing the speaker 403 to sound and the indicator light 404 to illuminate, promptly alerting personnel to perform inspection and maintenance. After the electrophoresis of the components is completed, when they pass over the smooth plate 5, the dripping electrophoretic liquid is guided by the inclined structure and smooth surface of the smooth plate 5, and finally flows into the collection tank 405 that is locked in the transmission frame 4, preventing the electrophoretic liquid from flowing turbulently on the surface of the smooth plate 5 and causing contamination. In addition, the drive mechanism 3 drives the rotating threaded cylinder 301 to rotate, and the rotating threaded cylinder 301 drives the threaded screw 302 to rise and fall through the threaded transmission, thereby adjusting the height position of the transmission frame 4 to adapt to the usage requirements of components with different height specifications.
