[0038] It is worth noting that in the prior art, if the directions of the plurality of clamping plates 240 on the two first conveying mechanisms 200 fail to be symmetrically arranged one by one, the operator needs to adjust the rotation shafts 220 by visual observation, which requires an operator with certain experience to adjust.

[0039] In the present application, the degrees of rotation of the rotation shafts 220 can be detected by the plurality of sensing plates 2511 on the sensing wheel 251 intermittently shielding the first sensing part 2524, and the operator can rotate the rotation shafts 220 to enable the directions of the plurality of clamping plates 240 on the two first conveying mechanisms 200 to be symmetrically arranged one by one.

[0040] In an embodiment, the plurality of clamping plates 240 are each provided with a clamping groove (not labeled), and the clamping groove is used to fix the plate 1.

[0041] Please refer to Figure 3 and Figure 6 In an embodiment, in order to control the rotation of the rotation shafts 220, the two first conveying mechanisms 200 each further include a driving member 260, which is preferably a stepping motor, and the driving member 260 is arranged at one end of the rotation shaft 220 away from the sensing wheel 251. Specifically, the driving member 260 is used to drive the rotation shaft 220 to rotate, and the user adjusts the degrees of rotation of the rotation shafts 220 through the driving member 260, so that the directions of the plurality of clamping plates 240 on the two first conveying mechanisms 200 can be symmetrically arranged one by one.

[0042] Please refer to Figure 3 and Figure 6 In an embodiment, in order to better control the rotation of the rotating shaft 220, the upper plate machine 10 further comprises a control device (not labeled) which is electrically connected with the driving member 260 and the first sensing part 2524. Specifically, the plurality of sensing plates 2511 on the sensing wheel 251 intermittently block the first sensing part 2524, and the control device obtains the corresponding degrees, so that the operator can observe on the control device whether the degrees of the rotation of the rotating shaft 220 of the two first conveying mechanisms 200 are the same, and if not, the operator can directly operate the driving member 260 to drive the rotating shaft 220 to rotate through the control device.

[0043] Please refer to Figure 1 In an embodiment, in order to better control the movement of the plate 1 between the two first conveying mechanisms 200 in the vertical direction from top to bottom, the opposite direction of the two first conveying mechanisms 200 further comprises two second sensing assemblies 270, the second sensing assembly 270 comprises a reset member 271 which is rotationally connected with the support 210 and a second sensing member 272 which is arranged on the support 210, the second sensing member 272 is provided with a third surface 2722 and a fourth surface (not labeled) which is opposite to the third surface 2722 at the second sensing groove 2721, the third surface 2722 is provided with a second sensing part 2724 which faces the fourth surface, the second sensing part 2724 is preferably an infrared sensing sensor, and the second sensing part 2724 is electrically connected with the control device. Specifically, the reset member 271 is further connected with a wire spring between the reset member 271 and the support 210, one first conveying mechanism 200 has two second sensing assemblies 270, and one second sensing assembly 270 has two reset members 271 and second sensing members 272. When the plate 1 moves between the two first conveying mechanisms 200 in the vertical direction from top to bottom, the lowermost plate 1 will touch the reset member 271, so that the reset member 271 is arranged in the second sensing groove 2721, the wire spring is compressed, and the reset member 271 blocks the second sensing part 2724. When the two reset members 271 of any one first conveying mechanism 200 are pressed by the plate 1, so that the two reset members 271 block the second sensing part 2724, the control device obtains the signal that the second sensing part 2724 of the first conveying mechanism 200 is blocked, and then stops the rotation of the driving member 260 of the first conveying mechanism 200, thereby controlling the plate 1 between the two first conveying mechanisms 200 to move more horizontally downward. When the reset member 271 is not pressed by the plate 1, the spring pushes the reset member 271 back, the spring restores to the stretched state, and the reset member 271 returns to the original position.

In this way, when the board 1 moves downward, it is more likely to abut against the multiple abutting portions 2711, thereby better controlling the downward movement of the board 1 in the vertical direction between the two first conveying mechanisms 200.

[0046] Please refer to Figure 5 In an embodiment, the board feeding machine 10 further comprises a second conveying mechanism 300 and a conveying mechanism 500.

The third conveying mechanism 400 comprises a guide rail 410 and a suction mechanism 420 in sliding connection with the guide rail 410. The guide rail 410 is used to provide a sliding structure for the suction mechanism 420. Specifically, the suction mechanism 420 moves the board 1 in the containing space 600 to the conveying mechanism 500 by suction, so that the conveying mechanism 500 can convey the board 1 on the suction mechanism 420 outward.

[0049] In other embodiments, the conveying mechanism 500 can convey the board 1 outward in a direction away from the containing space 600.

[0050] It is worth noting that the board pieces 1 include single-sided printed circuit boards and double-sided printed circuit boards, the accommodation space 600 can only stack multiple single-sided printed circuit boards, and multiple single-sided printed circuit boards or multiple double-sided printed circuit boards can be inserted between the two first conveying mechanisms 200.

[0051] Referring to Figure 3 In an embodiment, in order to push the multiple board pieces 1 in the accommodation space 600 upwards, the board feeding machine 10 further comprises a lifting platform 700 and a lifting mechanism 800, the lifting platform 700 is arranged in the accommodation space 600, the lifting mechanism 800 is arranged on the base 100, and the lifting mechanism 800 is fixedly connected with the lifting platform 700, and is used to drive the multiple board pieces 1 in the accommodation space 600 to move upwards along the vertical direction.

After the control device obtains the signal that the third sensing part 900 is blocked, the lifting mechanism 800 stops driving the lifting platform 700 to move upwards.
