Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to an integrated device for grinding and cleaning circuit boards. Background Technology

[0002] Printed circuit boards refer to bare boards without any components installed. During the circuit board manufacturing process, the circuit board substrate needs to be cut. After cutting, burrs will appear on the edges of the circuit board. These burrs will scratch the circuit board during subsequent processing, affecting the quality of the circuit board. Therefore, the cut circuit board must be ground by an edge grinding machine. However, after edge grinding, the residual particles generated by grinding and cutting also need to be removed. Thus, after edge grinding, cleaning is required.

[0003] Currently, the edge grinding and cleaning processes for printed circuit boards mostly use separate equipment. After edge grinding, the circuit board needs to be transferred to the cleaning equipment, which affects the overall processing efficiency and can easily cause damage to the circuit board during the transfer process.

[0004] Therefore, in order to solve the above problems, we propose an integrated circuit board edge grinding and cleaning device with an integrated transmission structure to realize integrated edge grinding and cleaning, thus ensuring processing efficiency. Utility Model Content

The milling cutter 62 is a diamond tool for grinding, while the polishing wheel 63 is made of nylon to remove burrs, achieving simultaneous grinding and polishing. The milling cutter 62 and the polishing wheel 63 are driven by a transmission component, so that the milling cutter 62 and the polishing wheel 63 rotate synchronously under the drive motor 64.

[0031] Please see Figure 1 and Figure 4In this embodiment, the pressing assembly includes a mounting plate 66.

The lower end surface of the mounting plate 66 is provided with an array of pressure rollers 67. Both ends of the pressure rollers 67 are rotatably connected to the mounting plate 66 through side plates. When the pressure rollers 67 contact the circuit board, they press and limit the circuit board to prevent displacement.

The pressure rollers 67 can rotate, so as not to affect the movement of the circuit board.

[0032] Please see Figure 1 and Figure 6 , Figure 7 In this embodiment, the cleaning assembly includes a cleaning plate 71 fixedly connected to the top of the cleaning rack 7 via a hollow rod. An array of flushing nozzles 72 is provided on the lower end face of the cleaning plate 71. The cleaning plate 71 has a hollow structure. The bottom of the hollow rod and the cleaning plate 71 are connected to each other, and the top of the hollow rod is connected to an external water pump via a pipeline. The supplied water is sprayed out through the flushing nozzles 72 to clean the circuit board. The drying assembly includes two blowers 81 fixedly installed on the top of the drying rack 8. A hot air box 82 is fixedly installed on the top of the inner side of the drying rack 8, and the tops of the blowers 81 and the hot air box 82 are connected. Furthermore, the lower end face of the hot air box 82 is provided with an air supply hole, and a heating tube is installed in the hot air box 82 to heat the incoming airflow. After the circuit board enters the cleaning rack 7, the external water supply pump supplies water, so that multiple rinsing nozzles 72 rinse the circuit board to remove the debris generated by the edge grinding. A wastewater recovery box (not shown in the figure) needs to be installed at the bottom of the cleaning conveyor belt 4 and the matching area of ​​the cleaning rack 7 to achieve the collection of cleaning wastewater. After rinsing, the circuit board enters the drying rack 8, and the top blower 81 blows airflow out of the drying rack 8, which generates hot air under the heating of the heating tube, making it convenient to air dry the circuit board.

[0033] During operation, the circuit board is placed in the feeding area of ​​the edge grinding conveyor belt 3. The edge grinding conveyor belt 3 drives the circuit board to move and first feeds the circuit board into the positioning frame 5. The CCD camera 51 visually identifies the position of the circuit board, so that the positioning plates 53 on both sides can adjust the position of the circuit board, thereby keeping the circuit board fed in each time on the same path, which is convenient for subsequent processing.

[0034] After positioning, the circuit board enters the edge grinding frame 6. At this time, the lifting cylinder drives the mounting plate 66 to move downward, so that the pressure roller 67 fits against the surface of the circuit board to achieve the limit. The pressure roller 67 can rotate, so as not to affect the movement of the circuit board. At the same time, according to the size of the circuit board, the servo motor 604 drives the threaded rod 603 to rotate, so that the lifting block 602 moves in the lifting groove 601. The height of the edge grinding assembly can be adjusted, and the position of the milling cutter 62 can be adjusted by the electric push rod to adapt to the size of the circuit board, so that the milling cutter 62 fits against the edge corner of the circuit board to achieve edge grinding. The outer recycling cover 65 can achieve simultaneous dust removal through the connection of pipeline and dust collection equipment, collect and centrally process the debris, reduce the residue of debris, and achieve simultaneous polishing during edge grinding, ensuring the edge grinding effect.

[0035] After edge grinding, the circuit board continues to be conveyed and passes through a smoothing table so that it enters the cleaning conveyor belt 4. The mesh belt structure of the cleaning conveyor belt is easy to adapt to the cleaning operation, thus sending the circuit board into the cleaning rack 7. The rinsing nozzles 72 rinse the surface of the circuit board and clean up the debris. At the same time, the cleaning conveyor belt 4 and the edge grinding conveyor belt 3 have different speeds to adapt to different processing requirements. Finally, the circuit board is sent into the drying rack 8 to achieve air drying.

[0036] Through the above steps, the circuit board is transported in an integrated manner by the edge grinding conveyor belt 3 and the cleaning conveyor belt 4, so that the circuit board passes through edge grinding, cleaning and air drying in sequence, thereby realizing the integrated processing of edge grinding and cleaning, reducing transfer steps, improving practicality, and solving the problem that the existing printed circuit board edge grinding and cleaning processes mostly use separate equipment, which affects the overall processing efficiency.
