Description

Technical Field

[0001] This utility model belongs to the field of printed circuit board processing technology, and specifically relates to an auxiliary device for laser cutting. Background Technology

[0002] Printed Circuit Boards (PCBs) are one of the core components in modern electronic devices. They are circuit boards used to support and connect electronic components. Electrical connections are achieved by printing conductive lines on an insulating substrate. PCBs not only simplify the assembly process of electronic products but also improve reliability and maintainability. In the processing of PCBs, laser cutting machines are used to cut them. During the laser cutting process, auxiliary devices are needed to assist in cutting the PCBs.

[0003] Existing laser cutting auxiliary devices work by placing the sheet material to be cut on the laser cutting machine and then controlling the auxiliary device to move the connected clamping module, causing the clamping blocks to hold the sheet material to be cut. This assists in cutting electrical printed circuit boards (PCBs). However, in actual use, when cutting the sheet material into PCBs, personnel need to frequently move the sheet material onto the laser cutting machine, requiring them to bend over, stand up, and reach out frequently. This consumes the personnel's energy and physical strength, and in the long run, it may cause certain safety hazards, which is not conducive to the use of the equipment and affects the cutting efficiency of electrical printed circuit boards. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an auxiliary device for laser cutting. This device can simultaneously lift the board to be cut and unload the cut electrical printed circuit board during the laser cutting process, saving personnel's energy and physical strength.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an auxiliary device for laser cutting, including a base frame, a top frame at the upper end of the base frame, symmetrically distributed guide grooves slidably arranged on the lower side of the top frame, a sliding seat one slidably arranged between the two guide grooves, a symmetrically distributed sliding seat two slidably arranged inside the sliding seat one, an electric push rod on the lower surface of each sliding seat two, a mounting seat on the telescopic end of each electric push rod, a drive module for driving the mounting seat to move horizontally between the top frame and the sliding seat one, and a clamping module for clamping the plate on the mounting seat.

[0006] As a further improvement of this utility model, the drive module includes an adjusting screw 1 rotatably disposed inside the top frame, the adjusting screw 1 being threadedly connected to a sliding seat 1, a drive motor disposed on the left side of the top frame, the output shaft of the drive motor being fixed to the adjusting screw 1 via a coupling, two adjusting screws 2 rotatably disposed inside the sliding seat 1, the two adjusting screws 2 being fixed to adjacent sliding seats 2 via couplings, and a dual-axis motor 1 disposed in the center of the sliding seat 1, the output shaft of the dual-axis motor 1 being fixed to adjacent adjusting screws 1 via couplings.

[0007] As a further improvement of this utility model, the clamping module includes a clamping seat disposed on the lower surface of the mounting base. A drive seat is disposed on the side of the clamping seat away from the vertical center of the base frame. Symmetrically distributed rotating shafts are rotatably disposed inside each clamping seat. A rotating rod is fixedly sleeved on the lower end of the outer arc surface of each rotating shaft. Symmetrically distributed rotating rods are rotatably disposed on the lower surface of the clamping seat via the rotating shafts. L-shaped clamping blocks are rotatably disposed between the ends of rotating rods one and two away from the clamping seat. An electronic control unit for driving the L-shaped clamping blocks to move is also disposed between the clamping seat and the drive seat. The component includes a worm gear fixedly sleeved on the upper side of the outer arc surface of the rotating shaft. The drive seat is equipped with symmetrically distributed supports. On the side of the support away from the vertical center of the drive seat, a worm is rotatably mounted between it and the inner wall of the adjacent drive seat. The worm is meshed with the adjacent worm gear. The drive seat is also equipped with an electrical control component for driving the worm to rotate. The electrical control component includes a dual-axis motor II located in the middle of the drive seat. The output shaft of the dual-axis motor II is fixed to the adjacent worm through a coupling. The L-shaped clamping block is equipped with a rubber pad on the side near the vertical center of the clamping seat.

[0008] As a further improvement of this utility model, a control box is provided on the front side of the base frame, and the electric push rod, drive motor, dual-axis motor one and dual-axis motor two are all electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by controlling the operation of the drive motor and electric push rod through the control box, and then by adjusting the thread relationship between the lead screw and the sliding seat, the sliding seat can be moved to adjust its horizontal position. By controlling the operation of the electric push rod through the control box, the clamping seat can be moved horizontally and vertically, which can lift the plate to be cut and unload the cut electrical printed circuit board, saving the manpower and energy.

[0011] Secondly, by controlling the operation of the dual-axis motor one through the control box, the sliding seat two drives the clamping seat to adjust its horizontal position, so that the clamping seat is close to the plate to clamp it in the front and back position.

[0012] Thirdly, by controlling the operation of the dual-axis motor 2 through the control box, the output shaft of the dual-axis motor 2 drives the worm gear connected to it to rotate, so that the L-shaped clamping block approaches the plate to clamp it in the left and right directions. In addition, the plate can be clamped in multiple directions by the cooperation of the L-shaped clamping block and the clamping seat.

[0013] Fourth, the rubber pads on the L-shaped clamps can effectively cushion the outer side of the board, allowing the L-shaped clamps to make flexible contact with the board, thereby effectively preventing damage to the edges of the board during the assisted cutting process.

[0022] like Figure 2 , 4 As shown, the drive module includes an adjusting screw 109 rotatably disposed inside the top frame 103. The adjusting screw 109 is threadedly connected to the sliding seat 105. A drive motor 110 is disposed on the left side of the top frame 103. The output shaft of the drive motor 110 is fixed to the adjusting screw 109 by a coupling. A symmetrically distributed adjusting screw 2 is rotatably disposed inside the sliding seat 105. The adjusting screw 2 is fixed to the adjacent sliding seat 106 by couplings. A dual-axis motor 111 is disposed in the middle of the sliding seat 105. The output shaft of the dual-axis motor 111 is fixed to the adjacent adjusting screw 109 by couplings.

[0023] like Figure 2 , 3 As shown, the clamping module includes a clamping seat 202 disposed on the lower surface of the mounting base 108. A drive seat 201 is disposed on the side of the clamping seat 202 away from the vertical center of the base frame 101. Symmetrically distributed rotating shafts 203 are rotatably disposed inside each clamping seat 202. A rotating rod 204 is fixedly sleeved on the lower end of the outer arc surface of each rotating shaft 203. Symmetrically distributed rotating rods 205 are rotatably disposed on the lower surface of the clamping seat 202 via the rotating shafts. L-shaped clamping blocks 206 are rotatably disposed between the ends of rotating rods 204 and 205 away from the clamping seat 202. A drive L-shaped clamping block 206 is also disposed between the clamping seat 202 and the drive seat 201. 06. The moving electronic control unit includes a worm gear 208 fixedly sleeved on the upper side of the outer arc surface of the rotating shaft 203. The drive seat 201 is provided with symmetrically distributed supports. On the side of the support away from the vertical center of the drive seat 201, a worm 209 is rotatably arranged between the support and the inner wall of the adjacent drive seat 201. The worm 209 is meshed with the adjacent worm gear 208. The drive seat 201 is also provided with an electronic control component for driving the worm 209 to rotate. The electronic control component includes a dual-axis motor 210 disposed in the middle of the drive seat 201. The output shaft of the dual-axis motor 210 is fixed to the adjacent worm 209 by a coupling.

[0024] like Figure 1 ,2 As shown, a control box 301 is provided on the front side of the base frame 101. The electric push rod 107, drive motor 110, dual-axis motor 111 and dual-axis motor 210 are all electrically connected to the control box 301.

[0025] When a laser cutting machine is needed to cut electrical printed circuit boards, the control box 301 controls the operation of the drive motor 110, causing the output shaft of the drive motor 110 to rotate the adjusting screw 109 connected to it. This, in turn, moves the sliding seat 105 by adjusting the thread relationship between the adjusting screw 109 and the sliding seat 105, thus adjusting the horizontal position of the sliding seat 105. The control box 301 also controls the operation of the electric push rod 107, causing its extension end to move the mounting base 108 downwards, thus adjusting the vertical position of the L-shaped clamp 206. Finally, the control box 301 controls the operation of the dual-axis motor 111, causing its output shaft to rotate the adjusting screw 109 connected to it. This, in turn, moves the sliding seats 106 on both sides towards or away from each other by adjusting the thread relationship between the adjusting screw 109 and the sliding seat 106, thus moving the clamping seat 206. 02. Adjust the horizontal position so that the clamping seat 202 is close to the plate for front-to-back clamping; control box 301 controls the operation of dual-axis motor 210, so that the output shaft of dual-axis motor 210 drives the worm gear 209 connected to it to rotate, and then through the meshing relationship between worm gear 209 and worm wheel 208, drives worm wheel 208 to rotate, so that worm wheel 208 drives rotating rod 204 to rotate through rotating shaft 203. Due to the rotation rod 204, rotating rod 205 and L-shaped... The clamping blocks 206 can form a parallelogram structure, allowing the L-shaped clamping blocks 206 to clamp the board from both sides. Furthermore, the L-shaped clamping blocks 206, in conjunction with the clamping seat 202, can clamp the board in multiple directions. Then, the control box 301 controls the drive motor 110 and the electric push rod 107 to move the board horizontally and vertically, thus lifting the board to be cut and unloading the cut electrical printed circuit board, saving personnel's energy and physical strength.

[0026] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, each of the L-shaped clamping blocks 206 has a rubber pad 207 on the side near the vertical center of the clamping seat 202. In daily use, the rubber pads 207 on the L-shaped clamping blocks 206 can effectively cushion the outer side of the board, allowing the L-shaped clamping blocks 206 to make flexible contact with the board, thereby effectively preventing damage to the edge of the board during the assisted cutting process.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
