[0032] The feeding assembly 200 is arranged on the front side of the conveying platform 100, and is used for picking up the circuit board 400 to be transported and placing the circuit board 400 to be transported into the feeding area 130.

[0033] The detection assembly 300 comprises a first detection photoelectric group 310 and a second detection photoelectric group 320. The first detection photoelectric group 310 and the second detection photoelectric group 320 are arranged in the transportation area 140, and the first detection photoelectric group 310 is close to the end of the feeding area 130. In the transportation direction M, the second detection photoelectric group 320 is arranged on one side of the first detection photoelectric group 310, and the distance B between the first detection photoelectric group 310 and the second detection photoelectric group 320 is greater than the length L of the circuit board 400 to be transported.

[0034] Specifically, the first detection photoelectric group 310 and the second detection photoelectric group 320 are arranged on the main body 110, and the first detection photoelectric group 310 and the second detection photoelectric group 320 can monitor whether the circuit board 400 to be transported passes below. First, the feeding assembly 200 places the circuit board 400 to be transported into the feeding area 130. As the conveying member 120 is transported, when the circuit board 400 to be transported is transported to below the first detection photoelectric group 310, the circuit board 400 to be transported is recognized by the first detection photoelectric group 310. Then, the circuit board 400 to be transported continues to run until it reaches a position below the second detection photoelectric group 320 and is recognized. Then, the feeding assembly 200 places the next circuit board 400 to be transported into the feeding area 130. In this way, the distance between the adjacent two circuit boards 400 to be transported in the transportation area 140 is equal, so that the phenomenon of the circuit board 400 to be transported being stuck or clamped is avoided, and the yield of the circuit board is improved.

[0035] Further, the control unit (not shown in the figure) is electrically connected with the first detection photoelectric group 310, the second detection photoelectric group 320 and the feeding assembly 200. Specifically, the control unit receives the signals of the first detection photoelectric group 310 and the second detection photoelectric group 320, so as to control the frequency of the feeding assembly 200 in placing the circuit board 400 to be transported, and realize automatic production.

[0036] Further, the feeding assembly 200 comprises a mechanical arm 210 and a suction cup 220 connected to the movable end of the mechanical arm 210. The mechanical arm 210 is used for driving the suction cup 220 to move, so as to pick up the circuit board 400 to be transported and place the circuit board 400 to be transported into the feeding area 130. Specifically, the circuit board 400 to be transported is picked up, and then the circuit board 400 to be transported is placed on the conveying platform 100 by the mechanical arm 210, so as to dock the next process. The structure is simple, and the operation is stable and reliable.

[0037] Further, the mechanical arm 210 is provided with a camera vision detection member 230 for identifying the position of the circuit board 400 to be transported. The camera vision detection member 230 is arranged at one end of the suction cup 220 and is used to identify the right-angle side of the circuit board 400 to be transported. Specifically, since the circuit board 400 to be transported is square in structure regardless of the size specification, and has four corners as right-angle sides, the pickup position of the circuit board 400 to be transported of the specification can be identified by identifying one of the right-angle sides, thereby ensuring the consistency of the placement position each time and avoiding the influence of the circuit board 400 to be transported being skewed on the subsequent process.

[0038] Further, the first detection photoelectric group 310 includes a plurality of photoelectric switches 330, and the plurality of photoelectric switches 330 are arranged at equal intervals along the width direction N of the main body 110. Specifically, the embodiment can monitor the entire width of the circuit board 400 to be transported, and the monitoring data is more accurate.

[0039] Further, the second detection photoelectric group 320 includes a plurality of photoelectric switches 330, and the plurality of photoelectric switches 330 are arranged at equal intervals along the width direction N of the main body 110. Specifically, the embodiment can monitor the entire width of the circuit board, and the monitoring data is more accurate.

[0040] Further, in the case where the first detection photoelectric group 310 includes a plurality of photoelectric switches 330 and the second detection photoelectric group 320 includes a plurality of photoelectric switches 330: the photoelectric switches 330 are detachably connected to the main body 110 through the connecting assembly 500, and the interval between adjacent two photoelectric switches 330 is adjustable. Specifically, the interval between adjacent two photoelectric switches 330 of the embodiment is adjustable to adapt to circuit boards of different widths, and the application range is wide.

[0041] Further, the connecting assembly 500 includes a fixed plate 510; the fixed plate 510 is fixedly connected to the main body 110, and the fixed plate 510 is provided with a plurality of waist-shaped holes 511 arranged at intervals along the width direction N of the main body 110; and the photoelectric switches 330 are connected to the waist-shaped holes 511 through bolts. Specifically, the interval between adjacent two photoelectric switches 330 is adjusted by adjusting the position of the photoelectric switches 330 connected in the waist-shaped holes 511, which is convenient for adjustment.

[0042] Further, the connecting assembly 500 further includes a back plate 520 connected perpendicularly to one side of the fixed plate 510. Specifically, the back plate 520 is arranged to facilitate the wiring of the plurality of photoelectric switches 330.

[0043] Further, the distance B between the first detection photoelectric group 310 and the second detection photoelectric group 320 is greater than the length L of the circuit board 400 to be transported by 10 cm. Specifically, 10 cm is reserved between two adjacent circuit boards 400 to be transported, so that the phenomenon of chasing the circuit board caused by misoperation or failure of the first detection photoelectric group 310 and the second detection photoelectric group 320 is avoided, and the phenomenon of chasing and clamping the circuit board is further avoided.
