[0049] Please refer to Figure 1-Figure 12 According to the single board sorting device and the control device, a single board sorting intelligent production line is constructed, which specifically includes an optical fiber sensor 1, a feeding telescopic cylinder 2, a feeding vacuum suction cup 3, a feeding rodless cylinder 4, a feeding telescopic cylinder fixing plate 5, a profile 6, a contact switch 7, a transmission component 8, an industrial camera 9, a photoelectric switch 10, a light source 11, a shading plate 12, a feeding vacuum suction cup connecting plate 13, a feeding rodless cylinder fixing plate 14, an angle code 15, a sorting telescopic cylinder 16, a sorting vacuum suction cup 17, a sorting rodless cylinder 18, a steering wheel 19, a sorting telescopic cylinder fixing plate 20, a sorting vacuum suction cup connecting plate 21, a sorting Rodless cylinder fixing plate 22, baffle 23, baffle telescopic cylinder 24, proximity switch 25, first pallet 26, second pallet 27, pallet receiving plate 28, electric push rod 29, flange 30, linear bearing 31, shaft 32, slot-type photoelectric switch 33, smooth strip 34, HMI35, trigger shaft ring 36, electric control box 37, turnover box 38, emergency stop switch 39, brush 40, camera fixing support 41, PLC, PC; the first pallet 26 is located in front of the head of the conveying component 8 and is placed on the front profile 6; the steering wheel 19 is connected to the bottom profile 6 by screws and is in direct contact with the ground.

Furthermore, the trigger collar 36 includes a fixing portion and a sensing portion extending along one side of the fixing portion, the fixing portion is fixedly connected to the shaft 32, and the sensing portion cooperates with the slot-type photoelectric switch 33; the slot-type photoelectric switch 33 is assembled in two groups for positioning the preset stroke in the second preset direction.

[0055] like Figure 4 , Figure 5 As shown, the smooth strip 34 is fixed to the tail of the conveying assembly 8 by the profile 6, and its height near the tail is the same as that of the conveying assembly 8, and its rear is 75° downward from the ground.

[0056] like Figure 1 , Figure 4 As shown, the second material collection device 38 is placed slightly behind the flow strip 34 and on the profile 6.

[0057] like Figure 3 As shown, the brush 40 is fixed by screws just below the lower end surface of the conveyor belt of the conveyor assembly 8. Figure 1 The illustrated orientation is taken as an example, and is used for the conveyor belt to contact the brush 40 when it moves from the upper end to the lower end, so as to remove the wood chips left on the conveyor belt.

[0058] like Figure 8 As shown, the HMI35 is fixed to the HMI fixing plate by screws and is located on the side of the conveying component 8; the HMI fixing plate is fixed to the side of the conveying component 8 by a slant through the profile 6, fixing the HMI35 and the emergency stop switch 39; the PC is installed in the electric control box 37; the PLC is connected to the PC; the emergency stop switch is connected to the PLC, when the equipment fails or the equipment needs to be stopped urgently, the emergency stop switch 39 is directly pressed, the signal is transmitted to the PLC, and the PLC controls the equipment to stop running; the HMI35 is connected to the PLC, and the operation screen is displayed, and the operation of the PLC manual program and the automatic program can be realized by operating the HMI35.

[0059] The control method of the present invention is specifically as follows:

[0060] S1. After power-on, it enters the power-on initial state, and the initial state is specifically: the feeding rodless cylinder 4 drives the feeding telescopic cylinder 2 to drive the feeding vacuum suction cup 3 back to the initial position of the feeding rodless cylinder 4, the sorting rodless cylinder 18 drives the sorting telescopic cylinder 16 to drive the sorting vacuum suction cup 17 back to the initial position of the sorting rodless cylinder 18, the baffle telescopic cylinder 24 drives the baffle 23 back to the lower limit, and the electric push rod 29 pushes the second tray 27 and the tray receiving plate 28 back to the upper limit, and the feeding vacuum suction cup 3 and the sorting vacuum suction cup 17 are in the closed suction state.

[0061] S2. After the initialization and debugging is completed, the operator turns on the industrial camera 9 on the PC, the image processing module is started, and the PC synchronously transmits the image processing results and startup information to the PLC. Click the automatic start button on HIM35, and the PLC first drives the feeding rodless cylinder 4 to move. After reaching the limit, it moves to the top of the first tray 26. The feeding telescopic cylinder 2 drops to the lower limit, and the contact switch 7 connected to the feeding vacuum suction cup 3 touches the plate on the first tray 26. The signal is transmitted to the PLC, and the PLC drives the feeding vacuum suction cup 3 to suck the plate tightly. The feeding telescopic cylinder 2 rises to the upper limit, and the feeding rodless cylinder 4 returns to the initial position, which is now located above the conveying component. At the same time, the conveying component 8 starts to run, and the feeding rodless cylinder 4 reaches the position and feeds back the PLC signal. The PLC stops the feeding vacuum suction cup 3 from sucking, and the plate is put down on the conveying component 8. As the conveying component 8 moves, the plate passes under the industrial camera 9, and the photoelectric switch 10 detects the plate and transmits the signal to the PLC. The PLC feeds back the signal to the PC. The industrial camera 9 receives the signal and takes a photo for recognition, and transmits the image processing result to the PLC. If the image processing result is a good board, the PLC feeds back a signal to the baffle telescopic cylinder 24, and the baffle telescopic cylinder 24 drives the baffle 23 to rise, blocking the board from moving forward. At this time, the board is above the proximity switch 25, and the proximity switch 25 is triggered, and the signal is transmitted to the PLC. The PLC drives the sorting telescopic cylinder 16 to descend, and the sorting vacuum suction cup 17 inhales after contacting the board. After sucking the board, the sorting telescopic cylinder 16 drives the sorting vacuum suction cup 17 to suck air. The tray 17 returns to the upper limit, and the sorting rodless cylinder 18 moves to the top of the second tray 27. After reaching the position, the sorting vacuum suction cup 17 stops sucking, and the plate falls onto the second tray 27. The sorting rodless cylinder 18 returns to the initial position. At the same time, the PLC receives a signal and transmits the signal to the electric push rod 29. The electric push rod 29 receives a signal to run the plate once. The electric push rod 29 runs for a preset time to drop to a preset height (such as running for 0.2s and dropping 4mm) until it runs to the next stroke to drive the equipment to pause, so as to facilitate the transportation of good plates. If the image processing result is a bad plate, the PLC feedback signal to the baffle telescopic cylinder 24, the baffle telescopic cylinder 24 and the baffle 23 do not move, and the plate continues to move on the conveying assembly 8 and runs to the smooth bar 34. The smooth bar 34 is 75° with the ground. The plate moves downward with the smooth bar 34 and finally falls into the second unloading collection box 38. This process will be cyclically carried out as the material is loaded. When the plates in the first tray 26 are detected, there is no signal from the optical fiber sensor 1 under the first tray 26. The optical fiber sensor 1 transmits the signal to the PLC, and the PLC stops the equipment.
