Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board screen printing devices, and in particular relates to a circuit board screen printing device with rapid positioning. Background Technology

[0002] The design and processing of circuit boards are strictly carried out according to different board layers. Special layers such as required logos, patterns and text symbols are printed on specific positions on the upper and lower surfaces of the printed circuit board to facilitate the later installation and maintenance of circuits on the circuit board. At present, most circuit boards are screen printed using screen printing machines.

[0003] The circuit board substrate needs to be completely fixed during screen printing to prevent positional displacement that could cause the screen printing pattern to become distorted and unclear. The existing method of fixing circuit boards is to use bolts to tighten the four corners of the circuit board on the printing table of the screen printing machine. This method is effective, but it requires tightening each bolt one by one, which is slow. Therefore, a fast positioning circuit board screen printing device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a fast-positioning circuit board screen printing device to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rapid positioning circuit board screen printing device, comprising a worktable and a positioning device. The positioning device includes a first base and a second base. A movable groove is formed on the upper surface of the first base, and a reciprocating screw is rotatably connected in the movable groove. Slider blocks are inserted through the circumferential sides of both ends of the reciprocating screw. A servo motor is provided on one side of the first base. A support plate with an "L"-shaped structure is provided on the upper surface of the slider. A sliding groove is formed on one side of the support plate, and a connecting block is slidably connected in the sliding groove. A fixing plate is provided on the right side of the connecting block, and a bolt is inserted through one side of the fixing plate. A contour block is provided on the left side of the fixing plate. The right end of the reciprocating screw penetrates one side of the inner wall of the movable groove, and a pulley is provided on the right end of the reciprocating screw. A mounting box is provided on the bottom surface of the worktable, and a connecting seat is provided inside the mounting box. A support column is provided on the upper surface of the worktable, and a support plate is provided on the upper surface of the support column. Multiple sets of suction pipes are inserted in the support plate, and suction cups are connected to the top ends of the suction pipes. A suction pump is suspended on the bottom surface of the mounting box.

[0007] Furthermore, a vertical plate is provided on the right side of the upper surface of the workbench, a screen printing head is provided on one side of the vertical plate, a circuit board body is provided inside the positioning device, the shape and size of the slider are adapted to the moving groove, the slider is threadedly engaged with the reciprocating screw, the threads at both ends of the reciprocating screw are opposite, one end of the bolt passes through the fixing plate and is attached to one side of the support plate, and the bolt is threadedly engaged with the fixing plate.

[0008] Furthermore, the first base and the second base have the same structure and are connected by a belt. The output end of the servo motor passes through one side of the first base and is fixedly connected to the left end of the reciprocating screw.

[0009] Furthermore, the tray is located in the middle of the positioning device, the bottom end of the suction pipe is fixedly connected to the connecting seat and communicates with the connecting seat, a connecting air pipe is connected between the suction pump and the connecting seat, one end of the connecting air pipe communicates with the suction pump, the top end of the connecting air pipe communicates with the connecting seat, and the tray and the support plate are at the same height.

[0010] This utility model has the following beneficial effects:

[0011] This invention utilizes a servo motor to drive a reciprocating screw, which in turn moves sliders at both ends. These sliders then move the upper support plate towards the center, allowing for adjustment based on the circuit board body. Simultaneously, a reverse bolt moves within the fixing plate, no longer contacting one side of the support plate. A moving contour block then clamps and secures the circuit board body on both sides, adapting to circuit boards of varying widths. Finally, an air pump, connected to an air pipe, connecting seat, suction pipe, and suction cup, adheres to and fixes the circuit board body placed on the upper surface of the support plate. This prevents horizontal movement of the circuit board during surface screen printing, resulting in faster fixation compared to traditional four-corner bolt positioning.

[0023] Please see Figure 1 - Figure 5 As shown, this utility model is a rapid positioning circuit board screen printing device, including a worktable 1 and a positioning device 2. The positioning device 2 includes a first base 21 and a second base 22. A moving groove is formed on the upper surface of the first base 21, and a reciprocating screw 210 is rotatably connected in the moving groove. Slider blocks 212 are inserted through the circumferential sides of both ends of the reciprocating screw 210. A servo motor 211 is provided on one side of the first base 21. A support plate 213 is provided on the upper surface of the slider 212. The support plate 213 has an "L" shaped structure. A sliding groove 214 is formed on one side of the support plate 213, and a connecting block 23 is slidably connected in the sliding groove 214. A connecting block 23 is provided on the right side of the connecting block 23. A fixed plate 230 has bolts 232 inserted on one side. A contour block 231 is provided on the left side of the fixed plate 230. The right end of the reciprocating screw 210 passes through one side of the inner wall of the moving groove. A pulley 2101 is provided on the right end of the reciprocating screw 210. A mounting box 101 is provided on the bottom surface of the workbench 1. A connecting seat 102 is provided inside the mounting box 101. A support column 103 is provided on the upper surface of the workbench 1. A support plate 104 is provided on the upper surface of the support column 103. Multiple sets of suction pipes 105 are inserted inside the support plate 104. A suction cup 106 is connected to the top of the suction pipe 105. A suction pump 107 is suspended on the bottom surface of the mounting box 101.

[0024] Furthermore, a vertical plate 11 is provided on the right side of the upper surface of the workbench 1, and a screen printing head 12 is provided on one side of the vertical plate 11. A circuit board body 3 is provided inside the positioning device 2. The shape and size of the slider 212 are adapted to the moving groove. The slider 212 is threadedly engaged with the reciprocating screw 210. The threads at both ends of the reciprocating screw 210 are opposite. One end of the bolt 232 passes through the fixing plate 230 and is attached to one side of the support plate 213. The bolt 232 is threadedly engaged with the fixing plate 230.

[0025] Furthermore, the first base 21 and the second base 22 have the same structure and are connected by a belt. The output end of the servo motor 211 passes through one side of the first base 21 and is fixedly connected to the left end of the reciprocating screw 210.

[0027] It should be noted that this utility model uses a servo motor 211 to drive a reciprocating screw 210 to rotate. The rotation of the reciprocating screw 210 drives the sliders 212 at both ends to move. The sliders 212 then drive the support plate 213 on the upper surface to move towards the center, thereby adjusting according to the circuit board body 3. At the same time, the reverse bolt 232 moves within the fixing plate 230 and no longer abuts against one side of the support plate 213. At this time, the moving contour block 231 fixes and clamps the circuit board body 3 on both sides to adapt to circuit boards of different widths. Then, the air pump 107 uses a connecting air pipe 108, a connecting seat 102, an air suction pipe 105, and a suction cup 106 to adsorb and fix the circuit board body 3 placed on the upper surface of the support plate 104. This prevents the circuit board from moving horizontally during the surface screen printing process. Compared with the original four-corner screw positioning, the fixing is faster.
