Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating equipment, and in particular to an anti-precipitation electrophoretic coating equipment. Background Technology

[0002] Electrophoresis tanks are typically rectangular in shape and contain electrophoresis solution. Electrode rods are placed inside the tank, energized, and then the parts to be electrophoretically coated are immersed in the solution for electrophoresis. However, precipitation can occur in the electrophoresis tank under the following circumstances: 1) When the concentration of the sample added to the electrophoresis tank exceeds the carrying capacity of the electrophoresis system, too many sample molecules will aggregate; 2) The buffer solution may deteriorate if left for a long time or stored improperly. Existing technologies require draining the electrophoresis solution for cleaning, which is cumbersome, time-consuming, and results in long downtime, affecting production efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-precipitation electrophoretic coating device, which solves the problem that the precipitation in the electrophoretic tank requires emptying the electrophoretic solution for cleaning, which is a cumbersome process with low cleaning efficiency.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] An anti-precipitation electrophoretic coating device includes an electrophoresis tank, wherein a filter screen is slidably connected to the inner wall of the electrophoresis tank, the longitudinal outer wall of the filter screen is arranged to fit the longitudinal inner wall of the electrophoresis tank, and the filter screen can slide along the height direction of the electrophoresis tank.

[0006] The top surface of the electrophoresis tank is rotatably connected to a rotating shaft, and an electrode rod is fixed on the outer surface of the rotating shaft. The lower end of the electrode rod extends into the electrophoresis tank. A rotating assembly that drives the rotating shaft to rotate is fixed on the outer wall of the electrophoresis tank, and lifting assemblies that drive the filter screen to rise are fixed at both ends of the rotating shaft.

[0007] Preferably, the rotating shaft is located at the exact center of the top surface of the electrophoresis tank, and the axial direction of the rotating shaft is the same as the width direction of the electrophoresis tank.

[0008] Preferably, there are two electrode rods on the outer surface of the rotating shaft, and the two electrode rods are symmetrically arranged at both ends of the rotating shaft.

[0009] Preferably, when the electrode rod is in a vertical position and its lower end is located in the electrophoresis tank, the axis of the electrode rod is perpendicular to the top surface of the filter screen.

[0010] Preferably, the rotating assembly includes a bracket fixed to the outer wall of the electrophoresis tank, a motor fixed to the top surface of the bracket, a first synchronous pulley fixed to the output end of the motor, a second synchronous pulley fixed to the end of the rotating shaft near the first synchronous pulley, and a synchronous belt connecting the first synchronous pulley and the second synchronous pulley.

[0011] Preferably, the lifting assembly includes two winding wheels symmetrically fixed at both ends of the rotating shaft. The two winding wheels are located on both sides of the electrophoresis tank. Two guide tubes are centrally symmetrically fixed at the center of the top surface of the electrophoresis tank. The two guide tubes are located on both sides of the rotating shaft. One end of the guide tube is directly opposite the lower part of the groove of one winding wheel, and the other end of the guide tube is perpendicular to the top surface of the filter screen and located above the electrophoresis tank. A steel cable is inserted into the guide tube. One end of the steel cable is fixed to the inner wall of the groove of the winding wheel, and the other end of the steel cable is fixed to the top surface of the filter screen. The width of the groove of the winding wheel is slightly larger than the diameter of the steel cable.

[0012] Preferably, the opening of the groove of the take-up reel is chamfered.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model is equipped with a rotating shaft, filter screen, motor, and winding wheel. During daily operation, the drive motor rotates, which in turn rotates the winding wheel to wind up the steel cable. This allows the filter screen to slide from bottom to top within the electrophoresis tank. During daily use, sediment adheres to the filter screen, achieving a cleaning effect. The sediment reaches the top surface of the electrophoresis tank until the top surface of the filter screen is flush with the top surface of the electrophoresis tank. The sediment can then be scraped off using a scraper or similar structure. Afterward, the filter screen descends, and electrophoresis can continue. The entire process does not require draining the electrophoresis solution, significantly reducing the number of operation steps compared to traditional technologies and improving cleaning efficiency.

[0015] 2. This utility model installs the electrode rod on the rotating shaft, thereby driving the electrode rod to rotate vertically upwards and expose the electrophoresis tank while cleaning the sediment. This allows for convenient inspection of the electrode rod's wear level. Furthermore, a single power device can simultaneously raise and lower the filter screen and rotate the electrode rod, thus greatly saving on equipment manufacturing costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5 This embodiment provides an anti-precipitation electrophoretic coating device, including an electrophoresis tank 1. A filter screen 2 is slidably connected to the inner wall of the electrophoresis tank 1. The longitudinal outer wall of the filter screen 2 is fitted to the longitudinal inner wall of the electrophoresis tank 1, and the filter screen 2 can slide along the height direction of the electrophoresis tank 1. Corner blocks 3 are fixed at the four corners of the bottom surface of the filter screen 2, and the four corner blocks 3 respectively fit into the four corners of the inner wall of the electrophoresis tank 1. This arrangement can ensure the stability of the filter screen 2 during lifting and sliding. A rotating shaft 4 is rotatably connected to the center of the top surface of the electrophoresis tank 1, and the axis of the rotating shaft 4 is the same as the width direction of the electrophoresis tank 1. Two electrode rods 5 are symmetrically fixed on the outer surface of the rotating shaft 4. When the electrode rods 5 are in a vertical state and the lower end is located inside the electrophoresis tank 1, the axis of the electrode rods 5 is perpendicular to the top surface of the filter screen 2, and the bottom surface of the electrode rods 5 is a certain distance from the top surface of the filter screen 2. A bracket 6 is fixed to the outer wall of the electrophoresis tank 1. A motor 7 is fixed to the top surface of the bracket 6. A first synchronous pulley 8 is fixed to the output end of the motor 7. A second synchronous pulley 9 is fixed to the end of the rotating shaft 4 near the first synchronous pulley 8. A synchronous belt 10 is connected between the first synchronous pulley 8 and the second synchronous pulley 9. When it is necessary to drive the electrode rod 5 to rotate so that the electrode rod 5 is vertically upward, the motor 7 is driven to rotate, which drives the first synchronous pulley 8 to rotate. This, in turn, drives the second synchronous pulley 9 to rotate through the asynchronous belt 10. This causes the rotating shaft 4 to rotate. Each rotation drives the rotating shaft 4 to rotate 180 degrees, thus enabling the electrode rod 5 to rotate to a vertically upward position.

[0024] Two take-up rollers 11 are symmetrically fixed at both ends of the rotating shaft 4. The two take-up rollers 11 are located on both sides of the electrophoresis tank 1. Two guide tubes 12 are centrally and symmetrically fixed at the center of the top surface of the electrophoresis tank 1. The two guide tubes 12 are located on both sides of the rotating shaft 4. One end of the guide tube 12 is directly opposite the lower part of the groove 1101 of one of the take-up rollers 11. The other end of the guide tube 12 is set perpendicular to the top surface of the filter screen 2 and is located above the electrophoresis tank 1. A steel cable 13 is inserted into the guide tube 12. One end of the steel cable 13 is fixed to the inner wall of the groove 1101 of the take-up roller 11, and the other end of the steel cable 13 is fixed to the top surface of the filter screen 2. The width of the groove 1101 of the take-up roller 11 is slightly larger than the diameter of the steel cable 13. In actual installation, the groove 1101 can be... The width of the winding wheel is set to 1.1 times the diameter of the steel cable 13, so that when the winding wheel 11 winds, the steel cable 13 can only be wound once inside the groove 1101. This ensures that when the shaft 4 rotates, the winding wheels 11 on both sides wind up the same length of the steel cable 13. In order to maintain consistency, the connection points between the steel cables 13 on both sides and the inner wall of the groove 1101 of the winding wheels 11 on both sides are also centrally symmetrically arranged on the top surface of the electrophoresis tank 1. The two connection points between the two steel cables 13 and the top surface of the filter screen 2 are also centrally symmetrically arranged on the top surface of the filter screen 2. The opening of the groove 1101 of the winding wheel 11 is chamfered, which facilitates the guidance of the steel cable 13 into the groove 1101.

[0025] It is important to emphasize that the steel cable 13 between the conduit 12 and the filter screen 2, and the electrode rod 5 adjacent to it, are staggered in the width direction of the electrophoresis tank 1. This ensures that the rotation of the electrode rod 5 is not obstructed. Simultaneously, as the electrode rod 5 is driven to rotate vertically upwards, the winding wheels 11 at both ends rotate, winding up the steel cable 13 and pulling the filter screen 2 upwards. It is also important to note that when the electrode rod 5 is vertically downwards, there is a certain gap between the bottom surface of the electrode rod 5 and the top surface of the filter screen 2. Therefore, the rotation of the electrode rod 5 and the upward movement of the filter screen 2 do not conflict. Finally, the rotating shaft 4 rotates 180 degrees, the top surface of the filter screen 2 is flush with the top surface of the electrophoresis tank 1, and the electrode rod 5 is vertically upwards. Afterwards, the operator can scrape off the sediment on the filter screen 2 and visually inspect the electrode rod 5.

[0026] Compared with the prior art, this utility model greatly facilitates the cleaning of sediment in the electrophoresis tank 1 because it does not require draining the electrophoresis solution or entering the electrophoresis tank 1 for cleaning. Furthermore, the electrode rod 5 can be flipped upwards while driving the filter screen 2 to rise, making it convenient to inspect the electrode rod 5.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
