Technical Field

[0001] The invention relates to the technical field of headphones, in particular to a method for manufacturing an insulating backlight iron frame light bar. Background Art

[0002] The backlight is located behind the liquid crystal display and can control the visual effect of the liquid crystal display module. Backlights can generally be divided into two types: CCFL and LED. CCFL lamps have the advantages of small tubes, simple structure, small temperature rise on the surface of the lamps, high brightness on the surface of the lamps, easy processing into various shapes, long service life, good color rendering, and uniform light emission. They are the ideal light source for the current TFT-LCD (liquid crystal screen) and are widely used in advertising light boxes, scanners, and backlight sources. LED light sources have the unique advantages of energy saving, environmental protection, long service life, safety, fast response, small size, rich colors, high controllability, and high photoelectric conversion efficiency. Therefore, light-emitting diodes are widely used in indicator lights of household appliances and rear fog lights of cars.

[0003] The existing light strips are widely used at present, and in some fine use ranges, in order to improve the waterproof performance of the light strips, certain requirements are placed on the insulation performance of the light strips themselves. In order to improve the insulation performance of the light strip carrier and the mounting body, insulating paint is applied on the back of the carrier and the mounting body. However, since the insulating paint has poor light transmittance and since the light strips are installed in fine equipment for use, the insulating paint coating can only apply a thin layer of insulating paint to the back of the light strip carrier to achieve the above-mentioned effect of improving the insulation performance of the light strip itself and facilitating adaptation and installation. However, the existing coating device or mechanism has poor effect on the coating of the back of the light strip carrier alone, and the insulating paint is easily applied to the edge of the light strip during coating.

[0004] Therefore, the present invention provides a method for manufacturing an insulating backlight iron frame light bar. Summary of the invention

[0005] The purpose of the present invention is to provide a method for manufacturing an insulated backlit iron frame light bar to solve the problem in the above background technology that the coating effect on a single side of the back of the light bar carrier is not ideal and the subsequent installation is difficult because the outer walls on both sides of the back of the light bar carrier are contaminated with paint.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention provides a technical solution: a method for manufacturing an insulated backlight iron frame light bar, wherein the light bar comprises a crystal protection portion at the front end of the light source and a light source carrier at the rear end, wherein connecting wires are embedded and packaged in the light source carrier, and the method is characterized in that:

[0029] a. First, use a mixing tank to stir the paint evenly;

[0030] b. Then use the spraying mechanism connected to the stirring tank to spray the rear end surface of the light bar, and the spraying mechanism sprays the paint on the rear end surface of the light bar through the top staggered paint ball head 3;

[0031] c. Then use a heater to air-dry the rear end of the light bar. The paint device 1 is provided with a stirring tank for storing paint, and the stirring tank is provided with a stirring device for stirring the paint. Before using the paint device 1 to paint the back of the light bar carrier, the user can put the paint into the stirring tank of the paint device 1 through the hopper 6 for stirring. After stirring evenly, the user can control the operation of the spraying mechanism through the touch screen 4. When the spraying mechanism is in operation, the evenly stirred paint will be sucked into the paint ball head 3. Because the paint ball head 3 can be flipped in place, when the rear end of the light bar is at the top of the paint ball head 3, When the rear end moves, the paint ball head 3 will rotate in place due to the contact force of the rear end surface of the light bar. When the paint ball head 3 rotates in place, the paint effect will be realized on the rear end surface of the light bar. Because the paint ball heads 3 are staggered, the rear end surface of the light bar can be perfectly loaded when it moves with the paint ball heads 3 as the support point. After the paint is completed, because the paint is completed by pulling the light bar to move, after the paint is completed, the user can control the operation of the heater set in the forward direction of the light bar through the touch screen 4 to achieve the air drying treatment of the paint surface.

[0032] Preferably, the spraying mechanism includes an extraction pump, a delivery pipe 5, a paint flow channel, and a plurality of paint ball heads 3. When the user uses the touch screen 4 to control the operation of the spraying mechanism, the extraction pump extracts the paint stirred evenly in the stirring tank, and then delivers it to the paint flow channel through the delivery pipe 5 connected on one side. After the paint enters the paint flow channel, because the paint ball head 3 is embedded in the paint flow channel, when the paint flows through the paint flow channel, the bottom surface of the paint ball head 3 will be stained with paint, and then the paint ball head 3 will rotate in place due to the force and apply the paint to the rear end surface of the light bar. After the paint passes through the other side of the paint flow channel, it will re-circulate into the stirring tank through the delivery pipe 5 connected on the other side.

[0033] Preferably, the paint flow channel is S-shaped, and a plurality of paint ball heads 3 are laid along the paint flow channel, the paint ball heads 3 are laid on the top of the paint flow channel, and the lower half of the paint ball heads 3 are embedded in the inner side of the paint channel. When the paint flows through the paint flow channel, it will contact with the lower half of the paint ball head 3 and be contaminated on the lower half of the paint ball head 3, and the paint ball head 3 will rotate in situ under the driving force generated by the contact with the rear end surface of the light bar and the driving force generated by the paint circulation, and the paint ball head 3 can achieve the effect of the paint on the rear end surface of the light bar when rotating in situ.

[0034] Preferably, the vertices of the plurality of paint ball heads 3 are staggered and converge into a straight line. The paint ball heads 3 arranged in this way can be completely coated with insulating paint when the light bar moves toward the front end with the rear end surface as the support surface.

[0035] Preferably, the paint ball head 3 at the rear part in the paint advancing direction does not contact the paint flowing in the paint flow channel. The paint ball head 3 at the rear part is higher in level than the paint ball head 3 at the front part, and the paint ball head 3 at the rear part is connected to the paint flow channel, and the paint ball head 3 at the rear part is used to evenly spread the paint on the rear end surface of the light strip.

[0036] Preferably, the outer periphery of the paint ball head 3 is equidistantly provided with crescent paint pieces 301, the arc opening formed by the crescent paint pieces 301 is oriented in the same direction as the forward direction of the light bar, and the crescent paint pieces 301 are made of a flexible material. In one embodiment, three crescent paint pieces 301 are provided, and the arc opening formed by the three crescent paint pieces 301 is oriented in the same direction as the forward direction of the light bar. The crescent paint pieces 301 not only have the function of uniformly distributing the paint, but also increase the power of the paint ball head 3 to rotate in place by using the circulating paint as the power source in the paint flow channel; Figure 2 As shown, in another embodiment, four crescent paint sheets 301 are provided. The crescent paint sheets 301 provided in this way can further enhance the power of the paint ball head 3 rotating in situ by using the paint flowing in the paint flow channel as a power source, thereby achieving a better paint effect on the rear end surface of the light strip.

[0037] Preferably, a scraper wall is provided in the rotating cavity of the rear paint ball head 3 with the rotation direction of the paint ball head as a reference coupling. When the rear paint ball head 3 rotates, it will stain the excess paint of the storage cabinet on the rear end surface of the light bar, so that a thin layer of insulating paint is formed on the rear end surface of the light bar, and the stained paint will be scraped off by the scraper wall provided on the inner wall of the rotating cavity opposite to the rotation direction when the paint ball head 3 rotates, and then flow back into the paint flow channel through the through hole.

[0038] Preferably, a groove is provided downwardly at the front end of the paint ball head 3, and a roller 7 is movably provided at the top of the groove. The arrangement of the roller 7 is to facilitate the more convenient movement of the traction light bar when the paint is applied to the rear end surface of the light bar.

[0039] Preferably, the bottom surface of the roller 7 is lower than the paint ball head 3. The roller 7 is provided so that the rear end surface of the light bar can be more closely fitted with the paint ball head 3 provided on the paint table 2 at the top of the paint device 1 as a whole, so as to achieve the purpose of seamless paint.

[0040] Preferably, a heater with an upward opening is provided at the bottom of the groove. When the coating device 1 is used to coat the rear end surface of the light bar with insulating coating, the user needs to control the operation of the heater provided at the end of the light bar in the forward direction through the touch screen 4. When the heater is in operation, the outside air will be filtered and sucked in, and then blown upward through the air outlet 8 via the fan and the heating wire. Because the air outlet 8 is directly below the forward movement of the light bar, the rear end surface of the light bar that has been coated with coating can be dried with warm air.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
