[0028] The piston rod one 315 is located on the displacement track of the touch rod 320, the clamping plate 311 and the threaded sleeve 39 are arranged in pairs and are symmetrical to each other along the vertical central axis of the bidirectional screw rod 38, the clamping plate 311 is arranged on the side of the coating machine body 1, and two clamping plates 311 are arranged, which are beneficial to clamping the two sides of the circuit board to be printed and stably placing the circuit board on the top of the coating machine body 1.

[0029] A spring one 318 is fixedly connected to the circumferential surface of the piston rod one 315, one end of the spring one 318 away from the piston rod one 315 is fixedly connected to the side of the air chamber 314, a control panel 35 is arranged on the side of the coating machine body 1, and the spring one 318 is beneficial to automatically resetting the piston rod one 315 when the piston rod one 315 is not extruded.

[0030] A spring two 319 is fixedly connected to the circumferential surface of the piston rod two 316, one end of the spring two 319 away from the piston rod two 316 is fixedly connected to the side of the air chamber 314, and the spring two 319 is beneficial to automatically resetting the piston rod two 316 when the piston rod two 316 is not extruded.

[0031] The fixed plate 317 is located on the top of the coating machine body 1, the ink tank 32 and the connecting pipe 33 are arranged in pairs, the printing plate 34 is located on the top of the coating machine body 1, a switch 312 is arranged on the top of the motor 37, the switch 312 is beneficial to directly controlling the motor 37 and facilitating the use of the motor 37.

[0032] In this embodiment, the circuit board to be printed is placed on the top of the coating machine, the coating machine is controlled through the control panel 35, the support frame 31, the ink tank 32, the connecting pipe 33 and the printing plate 34 are driven to move on the top of the coating machine body 1 to print and ink the circuit board material placed on the top of the coating machine body 1. In order to prevent the circuit board from shaking during printing, the motor 37 is started and the motor 37 is rotated in the forward direction, which drives the bidirectional screw rod 38 to rotate in the forward direction, which drives the two threaded sleeves 39 to move relatively, which drives the two clamping plates 311 to move relatively. The two clamping plates 311 are located on both sides of the coating machine body 1. When the clamping plates 311 move relatively, the two sides of the circuit board placed on the top of the coating machine body 1 are clamped, reducing displacement. The movement of the clamping plate 311 drives the trigger rod 320 to move. The piston rod one 315 is located on the displacement track of the trigger rod 320. When the trigger rod 320 moves, it presses the piston rod one 315 and moves it into the interior of the air chamber 314, pushing the gas in the air chamber 314 to move and pushing the piston rod two 316 at the other end of the air chamber 314. The piston rod two 316 is pushed out, which drives the fixed plate 317 to move downward. The fixed plate 317 is located on the top of the coating machine body 1. When the fixed plate 317 moves from top to bottom, it presses the circuit board from top to bottom, further reducing displacement and shaking. The relative movement of the clamping plate 311 clamps the two sides of the circuit board, reducing displacement and shaking of the circuit board during printing. This can ensure that the ink is evenly coated on the surface of the circuit board, avoiding uneven printing or misalignment. The downward pressure of the fixed plate 317 and the action of the air chamber 314 can ensure that the circuit board remains stable during printing and is not affected by external disturbances. This can improve the precision of ink coating and ensure the printing quality of the circuit board, especially for the production of high-precision circuit boards.

[0033] Embodiment 2

[0034] As shown in Figures 1-5 Based on the same concept as embodiment 1, the top of the coating machine body 1 is provided with a quick-drying assembly 4. The quick-drying assembly 4 includes an extrusion rod 41, one end of which is fixedly connected to the side of the clamping plate 311. The coating machine body 1 is fixedly connected with a long rod 42 on the side. The bottom of the long rod 42 is rotatably connected with a rotating shaft 43. The circumferential surface of the rotating shaft 43 is fixedly connected with a fan blade 44. The circumferential surface of the rotating shaft 43 is fixedly connected with an inclined rod 45. The fan blade 44 is located on the top of the coating machine body 1. The wind power generated by the fan blade 44 blows on the coating machine body 1, blowing and drying the printed ink on the printed circuit board.

[0035] The inclined rods 45 are located on the displacement track of the extruding rods 41, and the fan blades 44 are located on the top of the coating machine body 1, and the fan blades 44 are provided with a plurality of blades, which is beneficial to extruding the inclined rods 45 when the extruding rods 41 move, so that the inclined rods 45 rotate to generate wind power.

[0036] The circumferential surface of the rotating shaft 43 is fixedly connected with a torsion spring 46, one end of the torsion spring 46 away from the rotating shaft 43 is fixedly connected to the bottom of the long rod 42, and the design of the torsion spring 46 is beneficial to automatic reset when the rotating shaft 43 is not driven.

[0037] In the embodiment, the clamping plate 311 moves relatively, and the relative movement of the clamping plate 311 drives the extruding rods 41 to move. The inclined rods 45 are located on the movement track of the extruding rods 41, and when the inclined rods 45 are extruded, the rotating shaft 43 rotates along the long rod 42, and the rotating shaft 43 rotates to drive the plurality of fan blades 44 to rotate. The fan blades 44 rotate to generate wind power, and the fan blades 44 are located on the top of the coating machine body 1. The generated wind power blows on the top of the coating machine body 1, blows the printed ink on the circuit board on the top of the coating machine body 1, and when the inclined rods 45 are no longer extruded, the rotating shaft 43 is automatically reset by the torsion spring 46 and reversely rotates. The reverse rotation not only realizes automatic reset, but also drives the fan blades 44 to rotate twice to generate secondary wind power. The wind power generated by the fan blades 44 can effectively dry the ink printed on the circuit board. Since the top of the coating machine body 1 directly contacts the wind power, this direct wind power drying ink method can improve the drying efficiency and reduce the printing defects or product quality problems caused by incomplete drying of the ink. When the fan blades 44 reversely rotate, the secondary wind power generated can further enhance the ink drying effect. This design ensures that even if the ink is not completely dried, additional help can be obtained to ensure that the final product quality is more stable and the scrap rate is reduced.

[0038] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
