[0020] This utility model provides a burr removal device for PCBA processing. Example 1

[0021] Please see Figure 1 , Figure 2 and Figure 3 The device includes a fixed base 1, on the surface of which a power mechanism 2 is provided. The power mechanism 2 includes a support frame 201, a support plate 202, and a pressing plate 204. The support plate 202 is rotatably connected to the support frame 201. The support frame 201 is equipped with a motor that controls the rotation of the support plate 202. The motor is a mature device, and this application can use existing equipment on the market that meets the requirements. The support frame 201 supports and positions the support plate 202, and the pressing plate 204 approaches the support plate 202 to fix and clamp the cut PCB substrate, thereby improving the stability of the PCB substrate fixation and clamping.

[0022] The surface of the fixed base 1 is provided with a sliding groove 205. A support block 206 is slidably connected inside the sliding groove 205, and the support block 206 is fixedly connected to the support frame 201. The sliding groove 205 and the support block 206 support and fix the support frame 201, thereby improving the stability of the lateral sliding of the support frame 201.

[0023] The surface of the fixed base 1 is fixedly connected to an electric actuator 207, and the output end of the electric actuator 207 is fixedly connected to the support frame 201. The top of the support frame 201 is fixedly connected to an electric actuator 203, and the extrusion plate 204 is rotatably connected to the output end of the electric actuator 203. The electric actuator 207 controls the lateral movement of the support frame 201, improving the convenience of adjusting the position of the PCB substrate. The electric actuator 203 controls the up and down movement of the extrusion plate 204, so that the extrusion plate 204 and the support plate 202 move closer to each other to fix and clamp the PCB substrate. Example 2

[0024] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The support frame 201 is equipped with an edge grinding mechanism 3. The edge grinding mechanism 3 includes a support rod 301, a grinding wheel 303, and a suction head 311. The support rod 301 controls the grinding wheel 303 to move laterally, so that the grinding wheel 303 is in close contact with the surface of the PCB substrate, and the edge of the PCB substrate is ground to remove burrs, thereby improving the stability of burr removal. The suction head 311 is used to pick up the debris from the grinding process, preventing debris from flying everywhere and improving the environmental friendliness of PCBA processing.

[0025] A vacuum chamber 312 is fixedly connected to the bottom of the fixed base 1, and the output end of the vacuum chamber 312 is fixedly connected to the suction head 311. An electric pusher 308 that controls the movement of the support rod 301 is fixedly connected to the surface of the fixed base 1. The vacuum chamber 312 generates negative pressure suction, which causes the suction head 311 to suck up the debris from the grinding wheel 303 and suck the debris into the vacuum chamber 312, improving the convenience of debris storage. The electric pusher 308 controls the movement of the support rod 301, so that the grinding wheel 303 is in close contact with the PCB substrate.

[0026] A fixing frame 302 is rotatably connected to the surface of the grinding wheel 303, and the suction head 311 is fixed to the surface of the fixing frame 302. A telescopic spring 305 is fixedly connected to the surface of the fixing frame 302. The grinding wheel 303 is fixedly connected through the fixing frame 302, which improves the convenience of grinding the PCB substrate with the grinding wheel 303. The telescopic spring 305 provides a thrust to the fixing frame 302, so that the grinding wheel 303 is in close contact with the PCB substrate, which improves the stability of grinding and deburring the edge of the PCB substrate. Example 3

[0027] Please refer to it again. Figure 2 and Figure 4 The other end of the telescopic spring 305 is fixedly connected to the extrusion plate 304. The middle of the extrusion plate 304 is fixedly connected to the pressure sensor 307, and the pressure sensor 307 is fixedly connected to the support rod 301. The extrusion plate 304 fixes the telescopic spring 305. The pressure sensor 307 detects the pressure value between the grinding wheel 303 and the PCB substrate. When the pressure value changes, the position of the support rod 301 is adjusted in time to maintain a stable contact force between the grinding wheel 303 and the PCB substrate, thereby improving the stability of the grinding wheel 303 in grinding the PCB substrate.

[0028] The telescopic spring 305 has a telescopic rod 306 inside, and the two ends of the telescopic rod 306 are fixedly connected to the fixed frame 302 and the compression plate 304 respectively. The telescopic rod 306 supports and positions the telescopic spring 305, preventing the fixed frame 302 from shifting due to excessive deformation of the telescopic spring 305, and improving the stability of the lateral sliding of the fixed frame 302. The telescopic rod 306 and the telescopic spring 305 are combined to form a buffer device. Different buffer devices can be replaced according to the actual use.

[0029] A sliding rail 309 is fixedly connected to the surface of the fixed base 1. A sliding block 310 is slidably connected inside the sliding rail 309, and the sliding block 310 is fixedly connected to the support rod 301. The support rod 301 is fixed and supported by the sliding rail 309 and the sliding block 310, thereby improving the stability of the support rod 301 in lateral sliding.

[0030] Electric drive 1 (203), electric drive 2 (207), and electric drive 3 (308) are all mature devices. This application can use existing devices on the market that meet the requirements. In use, the following steps are taken: First, the cut PCB substrate is placed on the surface of the support plate 202. Then, an electric pusher 203 controls the pressing plate 204 to move downwards, bringing it closer to the support plate 202 to clamp and secure the PCB substrate. An electric pusher 308 controls the support rod 301 to move, ensuring the grinding wheel 303 is in close contact with the PCB substrate. An electric pusher 207 controls the support frame 201 to move laterally, which in turn controls the PCB substrate's lateral movement, allowing the grinding wheel 303 to grind the side of the PCB substrate. After grinding one side of the PCB substrate, the motor controls the support plate 202 to rotate, and then... The PCB substrate is rotated and the above operation is repeated to perform all-round polishing on the PCB substrate. When polishing irregularly shaped PCB substrates, the pressure sensor 307 detects the pressure value between the polishing wheel 303 and the PCB substrate. When the pressure sensor 307 detects an increase in pressure value, the electric motor pushes the support frame 201 to move laterally and control the polishing wheel 303 to move away from the PCB substrate. Similarly, when the pressure value decreases, the polishing wheel 303 is controlled to move closer to the PCB substrate, so that the polishing wheel 303 and the PCB substrate always maintain a suitable squeezing force, avoiding over-polishing and damage to the PCB substrate, and improving the burr removal effect of the PCB substrate.
