Description

Technical Field

[0001] The invention relates to the technical field of automated production, and in particular to a coating device for producing EVA lamp panels. Background Art

[0002] EVA light panels usually refer to light panels that use ethylene-vinyl acetate copolymer (EVA) as the base material. EVA is a lightweight, soft material with good cushioning, shock resistance, heat insulation, moisture resistance, and chemical corrosion resistance. Therefore, it is very suitable for making products such as light panels that require light transmission and softness.

[0003] During the production process, EVA light boards need to be coated. The coating can form a protective layer to protect the circuit of the EVA light board from short circuits caused by foreign objects. At the same time, it covers the copper wires to prevent them from falling off and improve the durability of the product. The coating can change the appearance color of the EVA light board, making it more beautiful and meeting the needs of different application scenarios. For example, the green solder mask oil commonly used in PCB boards not only plays a protective role, but also beautifies the appearance.

[0004] The existing EVA light panels have problems during the coating process, mainly due to dust falling from the surface due to panel contact or suspended matter in the air, which affects the quality of the panel coating. In addition, after the coating process, the EVA light panels do not rotate in the drying chamber, resulting in a fixed flow direction of the wind blown out by the upper and lower air blowing fan groups, lack of turbulence, which affects the effect of wind-accelerated drying and makes the drying time longer. The light emitted by the upper drying lamp tube group and the lower drying lamp tube group has different intensities in different areas, resulting in uneven heating of the wooden floor, which in turn affects the consistency of the drying effect. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a coating device for EVA light board production, which improves the efficiency, quality and adaptability of the coating and drying process, reduces quality problems in operation, is suitable for the production of LED light boards of different sizes, and has significant application advantages.

[0006] According to an embodiment of the present invention, a coating process line for the production of EVA light panels has at least the following beneficial effects: the coating device in this embodiment adopts a telescopic rod driven mechanism, and the movement of the telescopic rod drives the two coating gears to move synchronously. Under the synergistic effect of the guide column, the rotation of these coating gears can be converted into the rotational power of the rotating rod. The coating barrel connected to the rotating rod rotates accordingly, and the brush on the surface of the coating barrel effectively cleans the surface of the light panel to remove dust and other impurities.

Under the synergistic effect of the guide column 109, the rotation of these coating gears 110 can be converted into the rotational power of the rotating rod 111. The coating barrel 112 connected to the rotating rod 111 rotates accordingly, and the brush on the surface of the coating barrel 112 effectively cleans the surface of the light board 80 to remove dust and other impurities. This process significantly improves the surface cleanliness of the LED light board 80 during the coating process, thereby ensuring the uniformity and adhesion of the coating layer, and solving the quality problems caused by dust in the operation of the traditional device. In addition, a combination of a vertical plate 114 and a storage plate 113 is specially designed, and a sliding connection is achieved through a mounting groove 115.

Ventilation holes are designed on the support ring 211, which allow hot air to penetrate and evenly cover the coating plate, thereby achieving more efficient heat exchange. The top of the drying chamber 210 is equipped with exhaust holes, which helps to discharge moisture and excess heat and maintain the stability and uniformity of the drying process. By adding a rotary drive device 40, the device can drive the clamping mechanism 220 and the clamped coating plate to rotate, so that the coating plate can receive heat in all directions during the heating process.
