[0002] A circuit board is a carrier for integrated circuits. Circuit boards are manufactured using semiconductor processes, where numerous transistors, resistors, capacitors, and other components are fabricated on a small single-crystal silicon wafer. These components are then assembled into a complete electronic circuit using multilayer wiring or tunnel wiring methods.

Therefore, different nozzle specifications are often required when coating circuit boards of different sizes, resulting in poor flexibility in the coating operation and impacting efficiency, thus reducing the practicality of the coating equipment. To address these issues, we propose a circuit board solder resist coating equipment. Utility Model Content

[0018] Please see Figure 1-9This utility model provides a technical solution: including a mounting base 100, a control panel 110 on one side of the mounting base 100, a mounting bracket 120 fixed to the top edge of the mounting base 100 by bolts, an adjustment mechanism on the top of the mounting base 100, a transport mechanism on the top of the adjustment mechanism, a drive mechanism on the top of the mounting bracket 120, the drive mechanism including a mounting slide 410, a drive motor B420 and a lead screw A421, a sliding frame 430 on the outer side of the lead screw A421, a mounting column 440 slidably connected to the inner wall of the sliding frame 430, the mounting column 440 being fixedly connected to the mounting slide 410, and a coating mechanism on the top of the sliding frame 430; The coating mechanism includes a storage tank 510, a connecting bracket 520, a feed pump 530, a suction pipe 531, and a feed pipe 540. A coating control valve 550 is fixed to the bottom of the feed pipe 540, and an installation pipe 551 is fixed to the bottom of the coating control valve 550. A nozzle 560 is provided at the bottom of the installation pipe 551. A switching mechanism is provided at the bottom of the sliding frame 430, and a lifting mechanism is provided on one side of the switching mechanism. The circuit board is positioned and transported by the adjustment mechanism and the transport mechanism. The circuit board is coated by the cooperation of the drive mechanism and the coating mechanism. When it is necessary to adjust the coating aperture of the nozzle 560, the aperture of the nozzle 560 can be freely adjusted according to the size of the circuit board by the cooperation of the switching mechanism and the lifting mechanism. This improves the flexibility of the circuit board coating operation. The equipment can quickly coat circuit boards of different sizes, improves the efficiency of the circuit board coating operation, and thus improves the practicality of the coating equipment.

[0019] Specifically, the adjustment mechanism includes a mounting frame 210, which is bolted to the top of the mounting base 100. A drive motor A220 is bolted to one side of the mounting frame 210. A bidirectional lead screw 221 is provided at the output end of the drive motor A220. A pair of sliding seats A230 are provided on the outer side of the bidirectional lead screw 221. A mounting side plate 240 is fixed to the top of each pair of sliding seats A230. By setting the adjustment mechanism to drive the transport mechanism to move, the distance between the transport mechanisms can be adjusted according to the size of the circuit board, which facilitates the applicable transport operation of the circuit board and improves the flexibility of the equipment during use.

[0020] Specifically, the transport mechanism includes a conveyor 310, which is fixed to one side of the mounting side plate 240 by bolts. A limit baffle 320 is fixed to the top of the conveyor 310, and a circuit board body 330 is provided on the outside of the conveyor 310. By providing a transport mechanism, the distance between two sets of conveyors 310 can be adjusted by an adjustment mechanism. The conveyor 310 and the limit baffle 320 work together to perform suitable positioning and transport of the circuit board, which facilitates high-precision coating operations on the circuit board.

[0021] Specifically, a connecting plate 340 is fixed to the side wall of the conveyor 310, and a limiting slider 350 is fixed to the bottom of the connecting plate 340. A supporting slide rod 351 is slidably connected to the inner wall of the limiting slider 350, and the supporting slide rod 351 is fixedly connected to the mounting frame 210. By setting the mutual sliding of the limiting slider 350 and the supporting slide rod 351, the movement of the conveyor 310 can be limited and supported, ensuring the flexibility of the transportation operation.

[0022] Specifically, the switching mechanism includes a mounting column 610, which is fixed to the bottom of the sliding frame 430 by bolts. A stepper motor 620 is fixed to one side of the mounting column 610. A drive sleeve 621 is provided at the output end of the stepper motor 620. A driven insert shaft 630 is slidably connected to the inner wall of the drive sleeve 621. A nozzle fixing frame 640 is fixed to the bottom of the driven insert shaft 630. By setting up a switching mechanism to automatically switch the nozzle 560, the aperture of the nozzle 560 can be freely adjusted according to the size of the circuit board, which improves the flexibility of the circuit board coating operation. The equipment can quickly use the coating operation of circuit boards of different sizes, thereby improving the efficiency of the circuit board coating operation.

[0023] Specifically, the lifting mechanism includes a mounting frame 710, which is bolted to one side of the mounting column 610. A mounting groove 720 is bolted to one side of the mounting frame 710, and a servo motor 730 is bolted to the top of the mounting groove 720. A lead screw B731 is provided at the output end of the servo motor 730, and a sliding seat B740 is provided on the outer side of the lead screw B731. A drive plate 750 is fixed to one side of the sliding seat B740, and the drive plate 750 is rotatably connected to the driven insertion shaft 630. By providing the lifting mechanism, when the nozzle 560 needs to be switched, the servo motor 730 drives the lead screw B731 to rotate, thereby moving the nozzle 560 downwards. At this time, the nozzle 560 disengages from the mounting tube 551, facilitating the rotational switching of the nozzle 560 by the switching mechanism.

[0024] Working Principle: During use, the equipment is controlled via the control panel 110. The drive motor A220 rotates the bidirectional lead screw 221, which in turn moves a pair of sliding seats A230 in opposite directions. This movement of the sliding seats A230 moves the mounting side plate 240, which in turn moves the transport mechanism. The distance between the transport mechanisms can be adjusted according to the size of the circuit board. The conveyor 310 and the limit baffle 320 work together to position and transport the circuit board appropriately, facilitating high-precision coating operations. The feed pump 530 starts, drawing solder resist ink stored in the storage tank 510 through the suction pipe 531. The solder resist ink enters the nozzle 560 through the feed pipe 540 and mounting pipe 551, and is finally sprayed out through the nozzle 560. During this process, the drive motor B421 rotates the lead screw A421, which in turn moves the sliding frame 430 back and forth, thus moving the coating mechanism back and forth, causing the nozzle 560 to move back and forth. The device can perform coating operations on circuit boards. When the coating aperture of nozzle 560 needs to be adjusted, multiple nozzles 560 with different apertures are fixed by nozzle holder 640. When nozzle 560 needs to be switched, servo motor 730 drives lead screw B731 to rotate. The rotation of lead screw B731 drives slide seat B740 to move downward. Slide seat B740 drives nozzle 560 to move downward through nozzle holder 640. At this time, nozzle 560 is disengaged from mounting tube 551. Stepper motor 620 drives drive sleeve 621 to rotate stepwise. Drive sleeve 621 drives nozzle holder 640 to rotate through driven insert shaft 630, thereby driving nozzle 560 to move. The required nozzle 560 can be rotated to below mounting tube 551. Finally, lifting mechanism drives nozzle 560 to move upward and install nozzle 560 on mounting tube 551, realizing automated switching operation of nozzle 560. The aperture of nozzle 560 can be freely adjusted according to the size of circuit board.
