The rubber pad abuts against the circuit board, and the electric push rod continues to work. The connecting rod drives the slider to move inwards. When the slider moves inwards, it will drive the fixed rod and the long rod to move inwards. When the long rod moves, it drives the fixed block and the clamping block to move. When the anti-slip pad on the surface of the clamping block abuts against the output end of the electric push rod, the clamping block will limit the electric push rod, so that the output end of the electric push rod cannot continue to move downwards, thereby preventing the circuit board from being damaged because the operator fails to turn off the electric push rod in time.

Both the front and rear ends of the second pressing roller 107 are rotatably connected to the grinding bin 101. Belt wheels are provided at both ends of the belt 10, which can realize the rotation of the second pressing roller 107 and the first pressing roller 104 together;

[0030] Both the left and right ends on both sides of the grinding bin 101 are fixedly connected to the hydraulic cylinders 108. The output ends of the four hydraulic cylinders 108 penetrate through the grinding bin 101 and are fixedly connected to the support rods 109. The top of one end of the support rod 109 is rotatably connected to a roller 110, and the other end of the support rod 109 is fixedly connected to a frame 111. A sensor is arranged on one side of the support rod 109 close to the roller 110 to detect the position of the circuit board body 105 through the sensor, and a signal is sent through the sensor to control whether the hydraulic cylinder 108 and the second driving motor 112 are started;

[0031] The bottom of the frame 111 is slidably connected to the grinding bin 101. One side of the outside of the frame 111 is fixedly connected to the second driving motor 112. The output end of the second driving motor 112 penetrates through the frame 111 and is fixedly connected to a worm 113. One end of the worm 113 away from the second driving motor 112 is rotatably connected to the frame 111. A worm gear 114 is meshed on one side of the worm 113.

The top end of the roller shaft 115 penetrates through the frame 111 and is fixedly connected to a grinding block 116. One side of the grinding block 116 is attached to the circuit board body 105. By driving the worm 113 to rotate through the second driving motor 112 and utilizing the meshing effect between the worm 113 and the worm gear 114, the worm gear 114 and the roller shaft 115 are driven to rotate, and thus the side surface of the circuit board body 105 can be polished;

The output end of the third driving motor 202 penetrates through the support frame 201 and is fixedly connected to a bidirectional threaded rod 203. An inductor is arranged at the center of the bottom of the support frame 201 to detect the position of the circuit board body 105, and a signal is sent through the inductor to control whether the third driving motor 202 is started;

[0033] One end of the bidirectional threaded rod 203 away from the third driving motor 202 is rotatably connected to the support frame 201.

[0034] Working principle: Before using this multi-station circuit board edge grinding device, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 4As shown in the figure, first place the circuit board body 105 at one end of the conveying rack 102. Then, when the sensor detects the circuit board body 105, it starts the third drive motor 202 to drive the bidirectional threaded rod 203 to rotate. By using the threaded action between the bidirectional threaded rod 203 and the threaded sleeve 204, the rubber block 205 has a tendency to rotate. By using the limiting action of the guide rod 206 on the threaded sleeve 204, the two rubber blocks 205 can be driven to move horizontally along the guide rod 206, and the positions of circuit board bodies 105 of different models can be corrected.

[0035] Secondly, the circuit board body 105 is transported into the grinding chamber 101 through the conveying rack 102. The first drive motor 103 is started to drive the first pressing roller 104 and the belt 106 to rotate. By using the synchronous action of the belt 106, the second pressing roller 107 is driven to rotate together with the first pressing roller 104. By using the cooperation between the first pressing roller 104 and the second pressing roller 107, the circuit board body 105 can be slowly pushed forward and limited.

[0036] Finally, start the four hydraulic cylinders 108 to drive the support rods 109 to move towards the circuit board body 105 in the grinding chamber 101, so that the rollers 110 and the grinding blocks 116 can contact the side surface of the circuit board body 105. The second drive motor 112 is started to drive the worm 113 to rotate. By using the meshing action between the worm 113 and the worm wheel 114, the worm wheel 114 and the roller shaft 115 are driven to rotate, and the side surface of the circuit board body 105 can be polished.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
