[0002] A circuit board can be called a printed wiring board or a printed circuit board. A circuit board is composed of integrated circuits, crystal oscillators, trimmer capacitors, and printed circuit boards. The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. It is mainly used to connect various electronic components in electronic devices and serves as a structural support. When the circuit board is processed, burrs or unevenness will occur on its edge. Therefore, it is necessary to deburr and clean the edge of the circuit board. In the process of using the existing device for cleaning burrs on the edge of a circuit board, due to the fixed position limitation of the grinding wheel, it is difficult to grind and clean the burrs on the edges of circuit boards with different width dimensions, and the scope of use is relatively limited, which affects the applicability of the device when cleaning burrs on the edge of the circuit board. Based on this, the utility model designs a device for cleaning burrs on the edge of a circuit board to solve the above problems. Summary of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] As Figures 1 to 4 shown, the present invention provides a device for cleaning burrs on the edge of a circuit board, including a bottom platform 1. An electric push rod 2 is fixedly installed on the bottom platform 1 through a side frame 101. A loading seat 3 is fixedly installed at the telescopic end of the electric push rod 2. A pressing block assembly 4 is arranged on the loading seat 3. The circuit board 7 can be placed on the loading seat 3. The circuit board 7 abuts against the side wall of the loading seat 3. The circuit board 7 on the loading seat 3 is tightly pressed and fixed by the pressing block assembly 4. A horizontal guide rail 5 is fixedly installed on the bottom platform 1. A first motor 501 is fixedly installed at one end of the horizontal guide rail 5. The driving end of the first motor 501 is fixedly connected to a bi-directional screw shaft 502. Two positioning seats 503 are symmetrically and slidably connected to the horizontal guide rail 5. The two positioning seats 503 are respectively threadedly sleeved on both sides of the bi-directional screw shaft 502. A second motor 601 is fixedly installed on the positioning seat 503 through a grinding frame 6. The driving end of the second motor 601 is fixedly connected to a grinding wheel 602. A connecting frame 603 is fixedly connected to the side of the grinding frame 6. A limit stop block 604 is fixedly installed at a position corresponding to the grinding wheel 602 at one end of the connecting frame 603. The two limit stop blocks 604 can be used to limit and block the circuit board 7 on the loading seat 3.
[0019] Among them, as Figure 2 shown, the pressing block assembly 4 includes a transmission stud 401, a slide seat 402 and a pressing block 403. The bottom end of the transmission stud 401 is rotatably connected to the loading seat 3 through a connecting seat 404. The slide seat 402 is fixedly installed at the upper end of the pressing block 403. The slide seat 402 is slidably connected to the loading seat 3. The slide seat 402 is threadedly sleeved on the outside of the transmission stud 401. The transmission stud 401 in the pressing block assembly 4 is screwed and rotated to drive the pressing block 403 to press against the circuit board 7 on the loading seat 3.
[0020] Among them, as Figure 2 shown, the transmission stud 401 movably penetrates through the top of the material loading seat 3. The upper end of the transmission stud 401 is fixedly connected with a hand wheel 405, and the hand wheel 405 is convenient for screwing and rotating the transmission stud 401.
[0021] Among them, as Figure 2 shown, an anti-slip sheet 406 is fixedly installed on the bottom surface of the pressing block 403. The anti-slip sheet 406 is a component made of rubber. The anti-slip sheet 406 can play a good anti-slip effect on the circuit board 7 when it is pressed on the material loading seat 3.
[0022] Among them, as Figure 4 shown, a bearing seat 504 is fixedly installed inside the transverse guide rail 5. The bearing seat 504 is rotatably connected to one end of the bidirectional screw shaft 502 to ensure the stable effect when the bidirectional screw shaft 502 rotates and operates.
[0023] Among them, as Figure 3 shown, guide rods 301 are fixedly installed on both sides of the material loading seat 3. The limit stop blocks 604 are slidably sleeved outside the guide rods 301. The guide rods 301 can play a stable guiding and supporting role on the limit stop blocks 604.
[0024] Working principle of the present utility model:
[0025] During use, place the circuit board 7 on the material loading seat 3, and the circuit board 7 touches the side wall of the material loading seat 3. According to the requirements for cleaning the burrs on the edges of the circuit board 7 with different width dimensions, if it is necessary to adjust the positions of the two grinding wheels 602, use the first motor 501 to drive the bidirectional screw shaft 502 to rotate, which can drive the two positioning seats 503 to move closer to each other, thereby adjusting the positions of the two grinding wheels 602 and the limit stop blocks 604, so that the two limit stop blocks 604 respectively touch the two edges of the circuit board 7. At this time, the grinding wheels 602 can be in a state suitable for grinding the circuit board 7. Turn off the first motor 501, screw and rotate the transmission stud 401 in the pressing block assembly 4 to drive the pressing block 403 to press and fix the circuit board 7 on the material loading seat 3. Use the second motor 601 to drive the grinding wheels 602 to continuously rotate, and the electric push rod 2 drives the material loading seat 3 and the circuit board 7 to move to one side. The two grinding wheels 602 can synchronously grind the two edges of the passing circuit board 7, thereby cleaning the burrs on the edges of the circuit board 7. After the cleaning is completed, screw and rotate the transmission stud 401 in the pressing block assembly 4 to drive the pressing block 403 to move upward and reset, and then take out the circuit board 7 on the material loading seat 3.
