Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of active agent spraying devices, in particular to a kind of photosensitive dry film surfactant spraying device. BACKGROUND

[0002] In the production process of photosensitive dry film, uniform spraying of surfactant is one of the key steps to ensure product quality.

[0003] Traditional spraying device usually adopts nozzle spraying mode, and the surfactant is atomized by high-pressure gas and sprayed onto the substrate. In the spraying process of the commonly used photosensitive dry film surfactant spraying device, it is difficult to achieve uniform coverage of the substrate surface, especially for complex-shaped substrates, the problem of uneven spraying is particularly prominent. The main reason is that the design and airflow control of the nozzle are not fine enough, and the nozzle row density and position will lead to uneven spray distribution, forming the phenomenon of local excess or deficiency. Uneven surfactant spraying will directly affect the performance of the photosensitive dry film, leading to a decrease in adhesion and uniformity in the subsequent processing process. In the subsequent photosensitive dry film exposure and development process, local underexposure or overexposure may occur, thereby affecting the quality and yield of the final product. SUMMARY

[0028] As shown in Figure 1 and Figure 6 A protective cover 7 is further included, and the protective cover 7 is arranged on the upper part of the equipment base 1 and surrounds the transmission member 4 and the space on the left side of the upper part of the equipment base 1, effectively isolating the influence of the external environment, preventing dust, impurities and other pollutants from polluting the spraying process, ensuring the cleanliness and stability of the spraying environment, and further improving the spraying quality and product performance.

[0029] As shown in Figure 6 As shown in Figure 6 A mounting bracket 71 and a curing lamp 72 are further included, and not less than two mounting brackets 71 are arranged on the left part of the protective cover 7, the mounting brackets 71 are fixed on the inner wall of the protective cover 7, and the structure is stable and will not loosen due to vibration of the equipment; the lower part of each mounting bracket 71 is provided with a curing lamp 72, and the lamp group in the curing lamp 72 faces one side of the film transfer roller group 2, which accelerates the curing process of the active agent through light, ensures rapid curing of the coating, and improves the production efficiency and stability of the coating; specifically, the ultraviolet rays or visible light emitted by the curing lamp 72 can excite the photoinitiator in the active agent, promote the crosslinking reaction, and make the coating harden rapidly, thereby reducing the curing time and improving the speed and efficiency of the production line. At the same time, the rapidly cured coating can also enhance the adhesion and durability of the coating, and improve the overall performance of the product.

[0030] As shown in Figure 1 and Figure 6As shown, the protective cover 7 further includes a storage frame 8, a shutter 81 and a card seat 83. The storage frame 8 is fixed on one side of the upper part of the protective cover 7, and is fixed on the protective cover 7 by welding or bolts to ensure its structural stability and not loose due to vibration of the equipment. The storage frame 8 is provided with a plurality of card seats 83, and the card seats 83 are used to place the nozzle module 54. The nozzle module 54 is fixed in the card seat 83 by a slot or buckle, which is convenient for quick positioning and operation, and the nozzle module 54 can be quickly replaced when needed. Specifically, the design of the card seat 83 allows the nozzle module 54 to be easily inserted and pulled out, reducing the replacement time and improving the production efficiency.

[0031] The storage frame 8 is provided with a shutter 81 which is connected with the storage frame 8 through a sliding rail or a guide groove to ensure smooth sliding.

The movable rod of the cylinder 9 is provided with a push plate 91, and the push plate 91 moves synchronously with the movable rod of the cylinder 9. The lower part of the push plate 91 extends into one side of the film transfer roller group 2 and is close to the top of the film transfer roller group 2. The push plate 91 is used to push the film material on the film transfer roller group 2 to transmit along the correct path to ensure the smooth movement of the substrate during the spraying process.

[0033] Specifically, the design of the cylinder 9 allows the push plate 91 to make accurate reciprocating motion as needed. The lower part of the push plate 91 is close to the top of the film transfer roller group 2 and can contact one side of the transmitted film material. By changing the position of the push plate 91, the film material can be effectively guided to transmit along the predetermined path, avoiding the offset or wrinkling of the film material during transmission, thereby ensuring the smooth movement of the substrate during the spraying process, reducing the waste rate caused by the offset of the film material, and improving the overall production efficiency and product quality.
