Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and more specifically, to a circuit board solder resist production device. Background Technology

[0002] Circuit boards, also known as printed circuit boards, make circuits miniaturized and more intuitive. They play an important role in the mass production of fixed circuits and the optimization of power layout. Circuit boards are classified into three main categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. The solder mask layer refers to the part of the printed circuit board that is coated with solder mask ink.

[0003] In the process of using existing circuit board solder mask production equipment, the circuit board generally needs to be coated with one layer first, and then flipped over to apply another layer. During the flipping process, the circuit board is usually flipped manually, which can reduce work efficiency and is cumbersome, making it inconvenient to use. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a circuit board solder mask production device, which has the following beneficial effects:

[0017] (1) In this utility model, the box door is opened and the circuit board to be processed is placed between two placement seats. By rotating the screw on the top surface of the placement seat, the positioning plate at one end of the screw is moved. When the positioning plate abuts against the circuit board on the placement seat, the circuit board on the placement seat can be pressed and positioned by the use of the positioning plate. After pressing and positioning, the box door is closed and the inkjet printer is turned on. Solder resist ink can be sprayed out through the nozzle on the connecting tube. When one side of the circuit board is sprayed, the dual-axis motor is turned on. The dual-axis motor drives the synchronous wheel to rotate. By using the synchronous belt, the connecting rod can be rotated, so that the placement seat at one end of the connecting rod can be rotated, and the circuit board in the placement seat can be automatically flipped over. Thus, the other side of the circuit board can be sprayed again. The work continuity is high, which is conducive to improving its work efficiency.

[0018] (2) In this utility model, after spraying, the dual-axis motor is turned on, which makes the connecting rod rotate. When the connecting rod rotates, it drives the second gear to rotate. When the second gear rotates, it drives the first gear on the rotating rod to rotate, so that the fan blade at one end of the rotating rod rotates. This blows air onto the circuit board after spraying in the box, which can speed up the drying speed of the solder resist ink on the circuit board, thereby facilitating the fixation and adsorption of the solder resist ink on the circuit board and further improving its working efficiency.

Detailed Implementation

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, a circuit board solder resist production apparatus is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a circuit board solder resist production device according to an embodiment of the present invention includes a housing 1. Bushings are provided on both sides of the housing 1, and a connecting rod 2 passes through the bushings. One end of the connecting rod 2 is located inside the housing 1 and has a placement seat 13. A threaded hole is provided on the top surface of the placement seat 13, and a screw 12 is threaded into the threaded hole. One end of the screw 12 is located inside the placement seat 13 and has a positioning plate 14. A dual-axis motor 8 is installed at the middle position of the top surface of the housing 1. A synchronous pulley 3 is fixedly connected to the output end of the dual-axis motor 8 and one end of the connecting rod 2. A synchronous belt 4 is provided between the synchronous pulleys 3. A horizontal plate 7 is provided inside the housing 1, and an inkjet printer 6 is installed on the top surface of the horizontal plate 7. A connecting pipe 5 is provided on the bottom surface of the horizontal plate 7, and a nozzle 9 is installed on the connecting pipe 5. The inkjet printer 6 is connected to the connecting pipe 5 through a feed pipe. A door 20 is provided on the front surface of the housing 1, through which the door is opened. Door 20 is used to place the circuit board to be processed between two placement seats 13. By rotating the screw 12 on the top surface of the placement seat 13, the positioning plate 14 at one end of the screw 12 moves. When the positioning plate 14 abuts against the circuit board on the placement seat 13, the circuit board on the placement seat 13 can be pressed and positioned by the use of the positioning plate 14. After pressing and positioning, the door 20 is closed and the inkjet printer 6 is turned on. Solder resist ink can be sprayed out through the nozzle 9 on the connecting pipe 5. After one side of the circuit board is sprayed, the dual-axis motor 8 is turned on. The dual-axis motor 8 drives the synchronous wheel 3 to rotate. By using the synchronous belt 4, the connecting rod 2 is rotated, which makes the placement seat 13 at one end of the connecting rod 2 rotate. This automatically flips the circuit board in the placement seat 13, so that the other side of the circuit board can be sprayed again. The work continuity is high, which helps to improve its work efficiency.

[0029] In one embodiment, the inner walls of the housing 1 are provided with bearing seats on both sides of the connecting rod 2, and the bearing seats are provided with rotating rods 17. One end of the rotating rod 17 is fixedly installed with a fan blade 15. The rotating rod 17 is provided with a first gear 16, and the first gear 16 meshes with a second gear 19 provided on the connecting rod 2. The two side surfaces of the housing 1 are provided with through openings 18, and the front end surface of the housing door 20 is provided with through holes 21. After spraying, the dual-axis motor 8 is turned on, which causes the connecting rod 2 to rotate. The rotation of the connecting rod 2 drives the second gear 19 to rotate, and the rotation of the second gear 19 drives the first gear 16 on the rotating rod 17 to rotate, so that the fan blade 15 at one end of the rotating rod 17 rotates. This blows air onto the sprayed circuit board in the housing 1, which can accelerate the drying speed of the solder resist ink on the circuit board, thereby facilitating the fixation and adsorption of the solder resist ink on the circuit board and further improving its working efficiency.

[0030] In one embodiment, a plurality of through holes 21 are provided, and the plurality of through holes 21 are evenly distributed on the front surface of the door 20. A plurality of through openings 18 are provided, and the plurality of through openings 18 are evenly distributed on both sides of the housing 1. The use of through openings 18 and through holes 21 can maintain normal ventilation in the housing 1, thereby accelerating the drying speed of solder resist ink on the circuit board and improving its working efficiency.

[0031] In one embodiment, the inside of the housing 1 is provided with a collection box 10, and universal wheels 11 are installed on both sides of the bottom surface of the collection box 10. There are multiple universal wheels 11, and the multiple universal wheels 11 are evenly distributed in pairs on both sides of the bottom surface of the collection box 10. The collection box 10 can be used to collect excess solder resist ink.

[0032] In one embodiment, the collection box 10 is movably connected to the box body 1, wherein the collection box 10 can be removed from the box body 1 by opening the box door 20, thereby facilitating the cleaning of the solder resist ink in the collection box 10.

[0033] In one embodiment, the door 20 is hinged to the box body 1 via a hinge, wherein materials can be loaded or unloaded by opening the door 20.

[0034] In one embodiment, a plurality of fan blades 15 are provided, and the plurality of fan blades 15 are evenly distributed in pairs on both sides of the interior of the housing 1. The use of the plurality of fan blades 15 can accelerate the drying speed of the solder resist ink on the circuit board, thereby improving its working efficiency.

[0035] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] Working principle: Open the cabinet door 20 and place the circuit board to be processed between two placement seats 13. By rotating the screw 12 on the top surface of the placement seat 13, the positioning plate 14 at one end of the screw 12 moves. When the positioning plate 14 abuts against the circuit board on the placement seat 13, the circuit board on the placement seat 13 is pressed and positioned by the use of the positioning plate 14. After pressing and positioning, close the cabinet door 20 and turn on the inkjet printer 6. Solder resist ink can be sprayed out through the nozzle 9 on the connecting pipe 5. After one side of the circuit board is sprayed, turn on the dual-axis motor 8. The dual-axis motor 8 drives the synchronous pulley 3 to rotate. Through the use of the synchronous belt 4, the connecting rod 2 is rotated, so that the placement plate 14 at one end of the connecting rod 2 moves. Rotating the base 13 automatically flips the circuit board placed in it, allowing for spraying on the other side of the circuit board. This ensures high work continuity and improves efficiency. After spraying, turning on the dual-axis motor 8 rotates the connecting rod 2, which in turn drives the second gear 19. The second gear 19, in turn, drives the first gear 16 on the rotating rod 17, causing the fan blade 15 at one end of the rotating rod 17 to rotate. This blows air onto the sprayed circuit board in the housing 1, accelerating the drying of the solder resist ink on the circuit board and facilitating its adhesion, further improving efficiency.
