[0026] After the cutting process, the edges of the board material 22 may have edge defects 23 of varying sizes. For ease of explanation, Figure 5 The edge defect 23 in the sample was magnified. The traditional sorting method involves workers visually or using handheld instruments to sort out the plates 22 with edge defects 23 for rework. This method is not only inefficient but also not very accurate.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a board defect sorting device for sorting boards 22 with edge defects 23. It includes a sorting frame 1 and a rejection component embedded in the sorting frame 1. Both ends of the sorting frame 1 are provided with discharge grooves 8, and the bottom end of the sorting frame 1 is symmetrically provided with sliding grooves 3. Sliding members 13 with an L-shaped structure are inserted into the sliding grooves 3. A driving mechanism for moving the sliding members 13 is installed on the sorting frame 1. A detection component that contacts the edge of the board 22 to be inspected is elastically provided in the sliding member 13. Board receiving boxes are provided on both sides of the sorting frame 1, and the two receiving boxes respectively collect the sorted good products and defective products.

[0028] Optionally, both sides of the bottom end face of the sorting frame 1 are provided with protrusions 12. The rejection assembly includes symmetrically arranged rejection rollers 10 and rejection belts 4 installed between the two rejection rollers 10. The rejection belts 4 protrude from the bottom wall of the sorting frame 1 and can generate sufficient friction with the plate to be inspected. The protrusion height of the rejection belts 4 is 1-3 mm. The working mode of the rejection rollers 10 and rejection belts 4 is similar to that of the conveyor belt. The outer wall of the rejection rollers 10 is provided with protrusions (not shown in the figure) that engage with the rejection belts 4, similar to the connection method of the synchronous pulley and synchronous belt.

[0029] Both ends of the rejection roller 10 are fixed with drive shafts 9 that are rotatably inserted into the protrusions 12. A first motor 5 connected to the drive shafts 9 is fixedly installed on the side wall of the protrusions 12. The bottom end of the sorting frame 1 is fixedly mounted with support legs 11 in a rectangular array. Both ends of the sorting frame 1 are symmetrically welded and fixed with ear plates 2. The drive mechanism includes a lead screw 6 and a second motor 7 for driving the lead screw 6 to rotate. Both ends of the lead screw 6 are rotatably inserted into the two ear plates 2. The second motor 7 is fixed to the side wall of the ear plate 2, and the shaft of the second motor 7 is fixedly connected to the lead screw 6. The top of the sliding member 13 is threaded onto the lead screw 6, and a microcontroller 14 (preferably an STM32F103C8T6 microcontroller 14) is bonded and fixed to the side wall of the sliding member 13. The movable sliding member 13 performs a comprehensive inspection of the edge of the board to be inspected, thereby achieving accurate sorting of defective boards. The sliding member 13 performs contact inspection through the telescopic rod 15 and the push switch, and controls the first motor 5 to rotate forward / reverse, classifying the boards 22 with edge defects 23. This achieves automated picking of boards in a production line, improving picking efficiency.

[0030] The sliding member 13 has a mounting hole 18 at one end that extends into the slide groove 3. The detection component includes a push switch 21 that is bonded and fixed to the inner wall of the mounting hole 18 and a telescopic rod 15 that is slidably inserted into the mounting hole 18. A spring 19 is embedded in the mounting hole 18 and sleeved on the push switch 21. A push block 20 for squeezing the push switch 21 is fixed to the side wall of the telescopic rod 15. An anti-detachment protrusion (not shown in the figure) is provided at one end of the telescopic rod 15 that extends into the mounting hole 18. A water drop head 16 is fixedly connected to one end of the telescopic rod 15 that extends into the mounting hole 18. A ball bearing 17 is rotatably engaged in the water drop head 16.

[0031] The working principle of the technical solution provided by this utility model is as follows: During use, the plate to be tested enters the sorting frame 1 and comes into contact with the water droplet 16. The plate to be tested presses against the inclined surface of the water droplet 16, causing the telescopic rod 15 on the water droplet 16 to retract into the mounting hole 18. This causes the push block 20 on the telescopic rod 15 to contact the press switch 21, generating a first electrical signal to start the detection. When the plate to be tested falls to the inner wall of the sorting frame 1 due to gravity, the ball bearing 17 on the water droplet 16 comes into contact with the side wall of the plate to be tested. The microcontroller 14 starts the second motor 7, which drives the lead screw 6 to rotate. During the rotation of the lead screw 6, the sliding member 13 moves in the slide groove 3. As the sliding member 13 moves, the ball bearing 17 on the water droplet 16 slides on the side wall of the plate to be tested. The ball bearing 17 moves to the detection position. When the plate is dented, the spring 19 pushes the telescopic rod 15 to move the ball 17 into the edge defect 23. During the movement, the push block 20 separates from the push switch 21, generating a second electrical signal to start the first motor 5 to rotate forward. The forward rotation of the first motor 5 causes the rejection belt 4 to rotate, which moves the plate to be inspected out of the discharge chute 8 on one side of the sorting frame 1. An ACS712 current sensor is installed on the second motor 7. When the second motor 7 moves the sliding member 13 to the end point, the second motor 7 is resisted. The ACS712 current sensor generates a third electrical signal to start the first motor 5 to rotate in the opposite direction. The reverse rotation of the first motor 5 causes the rejection belt 4 to rotate, which moves the plate to be inspected out of the discharge chute 8 on the other side of the sorting frame 1.

[0032] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
