Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0019] A double-sided roller coating printing device for PCB board, such as Figure 1-Figure 3 As shown, it includes a control component 1, the middle part of the control component 1 is connected to the front and back sides with guide members, the front and back inner sides of the right part of the control component 1 are installed with two lifting members 2, and the front and back adjacent lifting members 2 are rotatably connected with two printing rollers 3, the front and back sides of the middle part of the control component 1 are movably connected with a balance roller 4, the front and back sides of the left part of the control component 1 are rotatably connected with five conveying rollers 5, and the upper side of the right part of the control component 1 is provided with a protective mechanism 6, which includes a first fixed rod 61, and the front and back sides of the right part of the control component 1 are connected. It is connected to a first fixed rod 61, there are three first fixed rods 61, a protective film 62 is sleeved between the middle first fixed rods 61, the protective film 62 is wrapped around the first fixed rods 61 on the left and right sides, the first fixed rods 61 are both located on the upper part of the lifting member 2, a second fixed rod 63 is connected between the front and rear sides of the right part of the control component 1, the second fixed rod 63 is located on the upper side of the first fixed rod 61 on the left, a cutting roller 64 is rotatably connected to the second fixed rod 63, a handle is installed on the cutting roller 64, and a fixing frame 65 is connected to the upper side of the left part of the control component 1.

[0020] like Figure 1 and Figure 4 As shown, it also includes an auxiliary heating mechanism 7, which includes a heating frame 71. The heating frames 71 are connected to the front and rear sides of the left part of the control component 1. A protective net is provided on the inside of the heating frame 71. Breeze components 72 are installed on the left and right sides of the heating frame 71. The breeze components 72 are all inclined structures that converge inward.

[0021] It should be noted that the PCB board is an important component used to connect and support electronic components in electronic devices. The PCB board forms a circuit network by laying conductive paths on an insulating substrate, thereby realizing electrical connection between electronic components. In the PCB board production process, double-sided roller coating printing technology is usually used to simultaneously coat photoresist or other coating materials on both sides of the PCB board, which can significantly improve production efficiency and coating uniformity. First, according to the actual thickness of the PCB board, the upper printing roller 3 is adjusted to a suitable position using the lifting member 2 so that the gap between the upper and lower printing rollers 3 can adapt to the thickness of the PCB board, thereby better performing the printing operation. At the same time, the position of the balance roller 4 is adjusted so that the printed PCB board can be better conveyed forward by the conveyor roller 5. During printing, dust may appear due to the lack of shielding of the control component 1. Or other impurities fall onto the printing roller 3, affecting the printing effect, the protective film 62 can be put on the first fixing rod 61 on the lower side, and then wrapped around the remaining two first fixing rods 61, so as to block the printing roller 3 and prevent impurities from falling. When the protective film 62 is contaminated, the cutting roller 64 can be rotated to make the cutting roller 64 flip to the left to cut the protective film 62, so as to replace the new protective film 62 to block it, which is beneficial to improve the printing effect. The printed PCB board is transported to the next production step by the conveyor roller 5. Under normal temperature, the coating material fixes slowly, which will affect the stability and performance of the coating material. The heating frame 71 heats the printed PCB board. The inclined structure of the breeze component 72 helps to gather hot air and disperse the hot air to the surface of the PCB board, which helps to solidify the coating material and ensure the stability and performance of the coating material.
