[0038] The production process of circuit boards involves many production processes and multiple production machines. For each production process or each production machine, manual loading of the circuit boards one by one is required and the circuit boards are fed to the corresponding process / machine. In order to improve the production efficiency of circuit boards, the loading efficiency of circuit boards needs to be improved.

[0039] To this end, the embodiment of the utility model proposes a circuit board loading mechanism and a circuit board cleaning machine, which can realize automatic loading of circuit boards through the cooperation of a carrier, an adsorption device, a moving device and a flipping device, and can continuously and automatically transport circuit boards without the need for staff to load the circuit boards one by one, thereby improving production efficiency and reducing labor costs.

[0040] Please refer to the attached Figure 1-3 , a circuit board feeding mechanism and a circuit board cleaning machine according to an embodiment of the present utility model are described in detail.

[0041] On the one hand, the embodiment of the present invention provides a circuit board feeding mechanism, such as Figure 1 and Figure 2As shown, the circuit board loading mechanism includes a carrier 100, an adsorption device 300, a moving device (not shown), a flipping device 400 and a receiving device 500; wherein, the carrier 100 is used to place the circuit board 200; the adsorption device 300 is arranged opposite to the carrier 100, and the adsorption device 300 is used to adsorb the circuit board 200 on the carrier 100; the moving device is used to drive the carrier 100 to move, so that the carrier 100 is close to or away from the adsorption device 300; the flipping device 400 is used to drive the circuit board 200 on the adsorption device 300 to flip; the receiving device 500 is used to receive the flipped circuit board 200.

[0042] Specifically, when loading circuit boards 200, multiple circuit boards 200 are placed together on the carrier 100. The moving device then drives the entire carrier 100 and the circuit boards 200 on it toward the suction device 300. When the carrier 100 and the suction device 300 are sufficiently close, the suction device 300 suctions the outermost (i.e., rightmost) circuit board 200 on the carrier 100. The moving device then drives the carrier 100 and the remaining circuit boards 200 back to their original positions. At this point, the flipping device 400 receives the circuit board 200 suctioned by the suction device 300 and releases it. The flipping device 400 then flips the circuit board 200, shifting it from a vertical orientation to a horizontal orientation. The receiving device 500 then receives the circuit board 200 and transfers it to the processing position for processing. When the previous circuit board 200 has been processed or is about to be processed, the driving device continues to drive the carrier 100 toward the adsorption device 300, allowing the adsorption device 300 to adsorb the next circuit board 200. According to the circuit board loading mechanism of the embodiment of the utility model, through the cooperation of the carrier 100, the adsorption device 300, the moving device and the flipping device 400, it is possible to realize automatic loading of the circuit boards 300, and continuously and automatically convey the circuit boards 200 without the need for workers to load the circuit boards 200 one by one, thereby improving production efficiency and reducing labor costs.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the receiving device 500 includes a frame 510 and a conveyor belt 520, wherein the conveyor belt 520 is disposed on the surface of the frame 510, and a mounting cavity 530 is formed between the bottom of the conveyor belt 520 and the frame 510. After the flipping device 400 flips the circuit board 200, the circuit board 200 is placed on the surface of the conveyor belt 520, and the conveyor belt 520 transports the circuit board 200 to the processing location.

[0044] Furthermore, if Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the carrier 100 includes a support base 110 and a support backrest 120. The support base 110 is disposed in the mounting cavity 530 on a side (i.e., the right side) close to the receiving device 500, and the bottom of the support backrest 120 is disposed on a surface of the support base 110 on a side (i.e., the left side) away from the receiving device 500. The surface of the support base 110 is used to place the circuit boards 200, and the support backrest 120 is used to support the circuit boards 200. When the circuit boards 200 are to be loaded, multiple circuit boards 200 are placed on the support base 110, and the circuit boards 200 are placed against the support backrest 120 to prevent the circuit boards 200 from falling.

[0045] Furthermore, in some embodiments of the present invention, protective frames (not shown) are provided on both sides of the support base 110. By providing protective frames on the front and rear sides of the support base 110, the circuit board 200 can be further prevented from falling from both sides of the carrier 100.

[0046] Furthermore, if Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a suction device 300 is disposed between the carrier 100 and the receiving device 500. The suction device 300 includes a plurality of suction cups 310 and a telescopic member 320 for driving the suction cups 310 toward or away from the carrier 100. Specifically, when the moving device drives the carrier 100 to a certain distance from the suction device 300, the telescopic member 320 drives the suction cups 310 to extend a certain distance to the left, so that the suction cups 310 contact the outermost circuit board 200 of the carrier 100. After the suction cups 310 absorb the circuit board 200, the telescopic member 320 drives the suction cups 310 to return to their original position, thereby removing a circuit board 200 from the carrier 100. The telescopic member 320 can be a device such as a gas rod.

[0047] Furthermore, if Figure 2 and Figure 3As shown, in some embodiments of the present invention, the flipping device 400 includes a rotating rod 410 and a rotating plate 420. The rotating rod 410 is arranged on the side of the frame 510 close to the carrier frame 100 (i.e., the left side), and the rotating plate 420 is connected to the rotating rod 410. A barb 421 is provided at the bottom of the rotating plate 420, and the rotating rod 410 is used to drive the rotating plate 420 to rotate. Specifically, when the suction cup 310 absorbs the outermost circuit board 200 of the carrier frame 100, and the telescopic member 320 drives the suction cup 310 to reset, at this time, the circuit board 200 absorbed by the suction cup 310 is just placed on the hook 421 of the rotating plate 420. After supporting the circuit board 200 by the hook 421, the suction cup 310 releases the circuit board 200. Then, the rotating rod 410 rotates, driving the rotating plate 420 to flip, so that the circuit board 200 is placed from vertical to horizontal, and is placed on the conveyor belt 520 of the receiving device 500, and the conveyor belt 520 transports the circuit board 200 to the processing position.

[0048] Furthermore, if Figure 2 and Figure 3 As shown, in some embodiments of the present invention, clamping plates 540 are provided on both sides of the transmission belt 520. The clamping plates 540 are connected to a driving device (not shown) for driving the two clamping plates 540 to clamp and adjust the circuit board 200 on the transmission belt 520. It should be noted that the driving device can be a device such as a cylinder. The driving device can drive the two clamping plates 540 toward each other, thereby clamping the circuit board 200 and adjusting the posture of the circuit board 200, so that the circuit board 200 can smoothly reach the processing position and prevent the circuit board 200 from tilting and affecting subsequent transmission.

[0049] Furthermore, if Figure 1 As shown, in some embodiments of the present invention, a detection device 550 is further provided on the conveyor belt 520, and the detection device 550 is used to detect the size of the circuit board 200. Specifically, the detection device 550 is used to detect the thickness of the circuit board 200 so that subsequent processing devices can set processing parameters according to the actual thickness of the circuit board 200, thereby improving processing accuracy.

[0050] Furthermore, in some embodiments of the present invention, the moving device includes a screw transmission assembly or a cylinder push assembly. The moving device can be disposed within the mounting cavity 530 of the frame 510 and connected to the support frame 100. The moving device, through structures such as the screw transmission assembly or the cylinder push assembly, drives the support frame 100 toward or away from the adsorption device 300. Alternatively, the moving device can be disposed on the side of the support frame 100 away from the adsorption device 300 (i.e., the left side), and can move the support frame 100 by pushing the support backrest 120.

[0051] On the other hand, an embodiment of the present invention also proposes a circuit board cleaning machine, which includes the circuit board loading mechanism of the above-mentioned embodiment. At the same time, the cleaning machine also includes one or more of a water washing mechanism, an ultrasonic cleaning mechanism, and a chemical washing mechanism. These mechanisms are arranged on the right side of the conveyor belt 520, and the conveyor belt 520 conveys the circuit boards to these mechanisms for cleaning operations.
