Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating equipment technology, and in particular to an electrophoretic coating device for the metal casing of a display. 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. The principle of electrophoretic coating was invented in the late 1930s. Electrophoretic coating is the most practical construction process for water-based coatings. It has the characteristics of water solubility, non-toxicity, and easy automation control. It has been widely used in the automotive, building materials, hardware, and home appliance industries. The metal casing of computer monitors usually needs to be processed using electrophoretic coating equipment.

[0003] However, in existing equipment, one hook corresponds to one metal shell. When the material is removed from the electrophoresis tank after coating, the single hanging is unstable and the material may fall back into the electrophoresis tank. At the same time, the electrophoretic coating equipment does not have a dynamic drying function. After the computer shell is coated, the material surface is naturally dried by heating the air in the equipment, which has low drying efficiency. Therefore, an electrophoretic coating device for the metal shell of the display is proposed. Utility Model Content

The air heater has an inlet pipe and an outlet pipe on both sides, and a filter cover is movably installed on the outside of the inlet pipe. The air pump has an exhaust pipe and an exhaust pipe on both sides, and the exhaust pipe and the exhaust pipe are fixedly connected. The bottom end of the exhaust pipe penetrates the top inner wall of the processing chamber and is fixedly installed with a first air collection box. Air guide pipes are fixedly installed on both sides of the first air collection box, and a second air collection box is fixedly installed at the bottom end of each of the two air guide pipes. The two second air collection boxes are fixedly connected to the inner walls on both sides of the processing chamber.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the electrophoretic coating device for the metal shell of this display, by setting up a horizontal plate, slider, suspension plate, insertion hole and insertion rod, adjusts the distance between each pair of insertion rods according to the size of the display shell. After adjustment, the metal shell is hung on the two suspension plates and positioned between the two insertion rods. The shell is hung on the two suspension plates at the same time, which can effectively increase its stability and prevent it from falling into the electrophoresis tank when picking up materials. The insertion rod can position the metal shell and prevent the metal shell from slipping and falling.

Compared with the prior art, the electrophoretic coating device for the metal casing of this display is equipped with an air heater, an air pump, an exhaust pipe, a first air collection box, an air guide pipe, a second air collection box, and a filter cover.

[0029] The drying structure 9 includes an air heater 901 and an air pump 902 fixedly installed on the top of the processing chamber 3. The air heater 901 has an inlet pipe and an outlet pipe on both sides. A filter cover 907 is movably installed on the outside of the inlet pipe. Multiple air inlets are provided on one inner wall of the filter cover 907. Stainless steel filter screens are installed inside the multiple air inlets and the ventilation holes 5. The outside of the inlet pipe is threaded, and the inside of the filter cover 907 is threaded. The threads on the inside of the filter cover 907 are compatible with the threads on the outside of the inlet pipe, allowing the filter cover 907 to filter the intake air. The filter and air pump 902 are respectively provided with an air extraction pipe and an air exhaust pipe 903 on both sides. The air extraction pipe and the air exhaust pipe are fixedly connected. The bottom end of the exhaust pipe 903 penetrates the top inner wall of the processing chamber 3 and is fixedly provided with a first air collection box 904.

[0030] Working principle: In use, first open the door 4. Then, adjust the distance between each pair of insertion rods 805 according to the size of the display casing. After adjustment, hang the metal casing on the two suspension plates 803, positioning the casing between the two insertion rods 805. Hanging the casing on both suspension plates 803 simultaneously increases its stability and prevents it from falling into the electrophoresis tank 2 when retrieving materials. The insertion rods 805 can position the metal casing, preventing it from slipping and falling. After the materials are suspended, start multiple push rod motors 6 simultaneously. The multiple push rod motors 6 drive the connecting rod 7, which in turn drives the horizontal plate 801. The horizontal plate 801 then drives the bottom suspension plate 803 and the metal casing. The shell is immersed in the electrophoresis tank 2 for electrophoretic coating. After processing, the shell is removed from the electrophoresis tank 2. Then, the air heater 901 and the air pump 902 are started. The air heater 901 heats the air that is drawn in. The air pump 902 draws in the air from the air heater 901 and introduces it into the first air collection box 904 through the exhaust pipe 903. The hot air in the first air collection box 904 is then introduced into the second air collection box 906 through the air guide pipe 905. The air in the first air collection box 904 and the second air collection box 906 finally acts on the metal shell that has been electrophoretically coated, realizing the dynamic drying of the metal shell. Since the air discharged from the air collection box has fluidity, it can improve the drying efficiency of the equipment.
