Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cutting, in particular to a special circuit board appearance processing device. Background Art

[0002] The shape processing of circuit boards is usually carried out by laser cutting. Laser cutting technology has high precision and flexibility, and can realize complex and special shape designs. By adjusting the laser cutting parameters, the cutting depth and shape can be accurately controlled, thereby realizing circuit boards of various shapes. In addition, laser cutting can also complete multiple processing steps in the same process, such as cutting, aperture processing and shape contour cutting, to improve processing efficiency and accuracy. Therefore, for circuit boards that require precise and complex shape designs, laser cutting is an ideal processing method.

[0003] When laser cutting a circuit board, debris often falls on the workbench. If it is not cleaned up, the subsequent circuit board will easily become warped and uneven when placed on the workbench, thus affecting the quality of cutting. Currently, the cleaning method of the workbench debris mainly relies on manual labor. However, small debris is difficult to observe with the human eye and is easy to leave residues. In addition, the operator may be injured by the laser cutting equipment, posing a safety hazard. Utility Model Content

[0004] The utility model aims to provide a special circuit board appearance processing device which has good cleaning effect and eliminates potential safety hazards.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A special circuit board appearance processing device includes a workbench, the upper surface of the workbench is installed with a vertical pole through a first movable module, the end of the vertical pole is installed with a second movable module, the lower surface of the slider on the second movable module is installed with a first electric push rod, the end of the telescopic end of the first electric push rod is installed with a laser cutter, and the lower surface of the laser cutter is installed with a hollow tube. A collection box is installed on the upper surface of the slider of the second movable module, a drawer is arranged inside the collection box, a fan is installed on the upper surface of the collection box, a filter is arranged at the connection between the fan and the collection box, a corrugated pipe is connected to the side surface of the collection box, and the end of the corrugated pipe is connected to the hollow pipe.

[0007] It can be seen that when the laser cutter cuts the circuit board, the hollow tube moves horizontally above the circuit board, and the suction force of the fan acts in the hollow tube. When fine debris is generated by cutting, it can be directly sucked into the collection box through the hollow tube and the bellows, and filtered by the filter, so that the fine debris is collected in the drawer, and the hollow tube changes with the cutting position of the laser cutter, so as to achieve point-to-point cleaning of the fine debris, thereby achieving a good cleaning effect, and the hollow tube can protect the laser to avoid harm to the operator during the cutting process, and the safety is higher. The first electric push rod drives the hollow tube to rise and fall, so that a sufficient distance can be left between the bottom of the hollow tube and the upper surface of the workbench, which is convenient for taking and placing the circuit board.

[0008] Furthermore, side panels are installed on both sides of the upper surface of the workbench, and a second electric push rod is installed on the outer surface of the side panel. The end of the telescopic end of the second electric push rod passes through the other side of the side panel and is installed with a clamping plate. A rubber pad is provided on the surface of the clamping plate. Two limit rods are connected to the side of the clamping plate facing away from the rubber pad, and the end of the limit rod passes through the other side of the side panel.

[0009] When placing the circuit board, one side of the circuit board is pressed against the surface of the first movable module, and then the second electric push rods on both sides push the clamping plate to move, so that the clamping plates on both sides are pressed against the two sides of the circuit board respectively, thereby positioning and fixing the circuit board and improving the cutting accuracy.

[0010] Furthermore, a mounting plate is installed on the upper surface of one side plate, a threaded rod is rotatably connected inside the mounting plate, a motor is installed on the outer surface of the mounting plate, and the output shaft of the motor is connected to the threaded rod, a nut seat is installed on the outer surface of the threaded rod, a connecting block is installed on the outer surface of the nut seat, a brush plate is installed on the end of the connecting block, and bristles are provided on the lower surface of the brush plate, and a material discharge trough is opened on the side of the upper surface of the workbench close to the first movable module.

[0011] After the circuit board is cut, the second electric push rod drives the splint to retract. At this time, the starting motor drives the threaded rod to rotate, which can drive the nut seat to move along its length. Through the connecting action of the connecting block, the brush plate can be driven to move and the larger debris on the surface of the workbench can be cleaned. Through the double cleaning effect, the workbench surface can be kept clean and tidy without residue, avoiding the subsequent warping and unevenness when the circuit board is placed, which affects the quality of cutting and avoids the safety hazards of manual cleaning.

[0012] Furthermore, a material receiving box is slidably mounted on the lower surface of the workbench, and the material receiving box is arranged directly below the material discharge chute.

[0013] The brush plate cleans the larger debris on the surface of the workbench, and the debris falls from the discharge chute and falls into the receiving box for collection.

[0014] Furthermore, an activated carbon filter is arranged on the top of the fan, and the activated carbon filter is threadedly connected to the fan.

[0015] The suction generated by the collection box not only sucks away the fine debris, but also the odor caused by cutting. The odor is filtered through the activated carbon filter and then discharged, thus ensuring the air quality on site and improving the comfort of the operators.

[0016] Furthermore, a fixing block is installed on the outer surface of the drawer, and the fixing block is connected to the collection box through bolts.

[0017] The drawer can be fixed in the collection box by setting the fixing block and the bolt, so as to avoid the drawer being loosened from the inside of the collection box during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When in use, the circuit board is placed on the surface of the workbench 100, and then the fan 109 and the first electric push rod 104 are started. The first electric push rod 104 drives the laser cutter 105 and the hollow tube 106 to descend, so that the hollow tube 106 is close to the surface of the circuit board. The circuit board is then cut by the laser cutter 105, and the fine debris generated during the cutting process can be sucked away by the suction force of the fan 109 and enter the collection box 107.
