Description

Technical Field

[0001] The utility model relates to the field of electrophoretic coating equipment, and more specifically, to a cathode electrophoretic coating cleaning device. Background Art

[0002] Electrophoretic coating is a special film-forming method. It immerses the conductive object to be coated in an electrophoretic coating tank filled with water-diluted and relatively low-concentration electrophoretic coating as the anode (or cathode), and another corresponding cathode (or anode) is set in the tank. A direct current is applied between the two electrodes, and a uniform and water-insoluble coating film is deposited on the object to be coated. Cathode electrophoretic coating is a coating technology that uses the action of an electric field to deposit negatively charged coating particles on the surface of the workpiece to form a uniform coating. In the production process of the cathode electrophoretic coating line, in order to ensure the coating quality of the workpiece, the workpiece needs to be cleaned and preheated.

[0003] However, when pre-cleaning the workpiece, most of the existing methods are carried out by flushing. Since the number of workpieces is relatively large, it cannot ensure thorough cleaning. At the same time, it cannot be air-dried after cleaning, which affects the coating quality during subsequent electrophoretic coating. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cathode electrophoretic coating cleaning device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 5 , a cathode electrophoresis coating cleaning device according to an embodiment of the present invention includes a bottom plate 1 for pre-cleaning a workpiece before cathode electrophoresis coating processing. A collection tank 16 for a collection assembly is provided on the bottom plate 1, which can facilitate the collection of the water after cleaning. A discharge pipe 17 is installed on its side wall, which is convenient for discharging the collected water for unified treatment and convenient for recycling and reuse, etc. Two groups of cleaning pipes 18 for cleaning assemblies are symmetrically welded at both ends of the bottom plate 1 along the center of the bottom plate 1. Cleaning nozzles 20 are inclined and equidistantly installed on the cleaning pipes 18, which can facilitate the cleaning operation of the workpiece. A water inlet pipe 19 is horizontally connected to the middle of the cleaning pipe 18, and it is connected to a water tank through a pump, which can facilitate the pumping and flushing. The cleaning water can be hot water, which is convenient for flushing and can also be preheated according to the situation.

[0026] Please refer toFigures 1 - 5 In order to conveniently move the whole workpiece, facilitate cleaning and move it into the cathode electrophoresis coating station for processing operations, two sets of linear guide rail devices 6 of the moving mechanism are symmetrically arranged at both ends of the vertical plate 2. A guide rail slider 7 is slidably arranged thereon, which can be driven by a linear motor or reciprocated by a reciprocating lead screw or other means. This is a relatively mature technology and will not be elaborated here. A moving plate 8 can be installed between the two guide rail sliders 7 by screws. The two ends of the linear guide rail device 6 are installed on the fixed block 5, and an electric push rod 3 is installed under the fixed block 5. The bottom end of the electric push rod 3 can be connected to the ground or the like through the mounting plate 4 to ensure the overall stability.

[0027] Please refer to Figures 1 - 5 In order to conveniently rotate the workpiece slowly, ensure thorough and comprehensive cleaning, and also assist in air drying after cleaning to facilitate subsequent electrophoresis coating, a motor 9 of the rotating assembly is installed in the middle of the moving plate 8. The output end of the motor 9 is fixedly connected to the rotating rod 10 through a coupling, which can conveniently drive the rotating rod 10 to rotate. The circumferential side of the rotating rod 10 is equidistantly provided with placing hooks 11 for conveniently placing the workpiece, which can also be a placing rack or clips, etc., and is set according to the specifications and shapes of the workpieces to facilitate placing the workpieces and convenient for cleaning, electrophoresis and other processing. Two sets of hot air blowers 12 of the air drying assembly are symmetrically arranged at both ends of the top of the moving plate 8 (which can also be a blower, set and selected according to the actual situation), which is convenient for air drying the workpiece after cleaning. The output end of the hot air blower 12 is provided with an air drying pipe 14 through a connecting pipe 13. The air drying pipe 14 is equidistantly provided with air outlets 15 below. The air outlets 15 penetrate through the moving plate 8 and extend to the lower part, which can conveniently air dry the workpiece after cleaning.

[0028] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0029] By placing the workpiece to be cleaned on the placement hook 11, at this time, the linear guide device 6 works, driving the guide rail slider 7 to move, and then the workpiece under the moving plate 8 can be driven to move between the two vertical plates 2. At this time, the linear guide device 6 stops working, and the electric push rod 3 contracts, driving the entire moving plate 8 to move downward, so as to adjust the height between the workpiece and the cleaning nozzle 20. After the adjustment is completed, water can be introduced through the water inlet pipe 19 and sprayed out through the cleaning pipe 18 and the cleaning nozzle 20 to perform a flushing operation on the workpiece. At this time, the motor 9 works, driving the rotating rod 10 and the placement hook 11 to slowly rotate, and then the workpiece can be driven to rotate to ensure thorough and comprehensive cleaning. After the cleaning is completed, the linear guide device 6 continues to work, driving the moving plate 8 to move, and at the same time, the hot air blower 12 works, blowing the dry hot air out through the air outlet 15 under the connecting pipe 13 and the air drying pipe 14. At this time, the motor 9 continues to rotate, and the cleaned workpiece can be air-dried to facilitate subsequent electrophoretic coating processing. The cleaning water is collected through the collection tank 16 and discharged through the discharge pipe 17, which is convenient for unified treatment and recycling.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
