Thus, the operation process design for achieving precise docking between the circuit board and the processing equipment is adopted. Instead, after feeding, precise alignment between the processing equipment and the circuit board is carried out through induction equipment. This further increases the processing time required, resulting in the retention of circuit boards on the feeding device, low overall production efficiency of the circuit boards, and low docking and processing accuracy. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] Please refer to Figures 1-4 , the present invention provides a technical solution: a high-precision circuit board loading device, including:

[0033] Loading guide frame 1;

[0034] Support frame 2, which is arranged on the side of the loading guide frame 1;

[0035] Loading seat 3, the bottom of which is connected to the slide seat 4 through the first cylinder 6 for lifting, and the slide seat 4 is slidably arranged on the first driving guide rail 5 along the direction of the loading guide frame 1;

[0036] At least two alignment mechanisms, which are arranged on both sides of the loading guide frame 1, including a vertical frame 7 and an induction platform 11 and a suction cup frame 14 driven by a second cylinder 13 arranged on the vertical frame 7 from bottom to top, and the induction platform 11 senses the induction points on both sides of the axis of the circuit board 100;

[0037] Adjustment mechanism, which is used for driving and adjusting the position of the alignment mechanism on the horizontal plane.

[0038] The feeding base 3 includes an inner support plate inside the inner feeding guide frame 1 and an outer support plate outside it. Before feeding the circuit board components, the feeding guide frame 1 supports the axis of the circuit board components. The support frame 2 supports the same-side corners. The inner and outer support plates are staggered with the feeding guide frame 1 to lift, convey, and feed the circuit board 100 with the position adjusted.

[0039] The induction platform 11 is arranged on the vertical frame 7 through a lifting drive of a fourth drive rail 12 to support the sagging part of the circuit board 100 and ensure its overall flatness, thereby making the induction and alignment between the induction platform 11 and the induction points on the circuit board 100 more accurate.

[0040] Sensors 15 are correspondingly arranged on the side surface of the support frame 2 and the vertical frame 7. Sensors 15 are correspondingly arranged on the opposite surfaces of the sliding seat 4 and the vertical frame 7. This design makes the position alignment between the circuit board 100 and the feeding base 3 by the alignment mechanism more accurate.

[0041] The adjustment mechanism includes a third drive rail 10 arranged parallel to the feeding guide frame 1, a base 9 slidably arranged on the third drive rail 10, and a second drive rail 8 arranged on the base 9 to drive the vertical frame 7 to move laterally along the feeding guide frame 1, improving the stability of the position adjustment of the alignment mechanism and the circuit board 100.

[0042] The above drive mechanism can also adopt common drive devices such as motors, cylinders, or hydraulic cylinders in a corresponding drive and movement manner.

[0043] The working principle of a high-precision circuit board feeding device in this embodiment includes: when in use, as Figure 1 、 3 With the change of the device structure, the first drive rail 5 drives the feeding base 3 to move to the specified position at the left end. The previous processing section on the left side of the feeding guide frame 1 conveys the circuit board 100 onto the feeding guide frame 1. The feeding guide frame 1 and the support frame 2 respectively support its axis and the left-side corners. The fourth drive rail 12 drives the induction platform 11 to support the sagging area of the circuit board 100. The circular induction area on the induction platform 11 senses the induction points of the circuit board 100 inside it. Through the adjustment mechanism, the alignment mechanism is driven to move, making the center of the circular induction area accurately aligned with the induction points. Then, the second cylinder 13 drives the suction cup frame 14 to move downward to adsorb and grasp the circuit board 100. As Figure 4As shown, after being slightly lifted, the alignment mechanism is continued to be driven to move, so that the sensors 15 on the support frame 2, the slide seat 4 and the stand 7 sense each other, and the circuit board 100 moves to the specified position of the loading seat 3, and the suction cup seat 14 moves up; finally, the first cylinder 6 drives the loading seat 3 to lift, and the circuit board 100 is separated from the loading guide frame 1, and the first driving guide rail 5 transports the circuit board to the other end. The grabbing device here does not need to be aligned, and can be directly moved toward the circuit board 100 for accurate docking, thereby ensuring the accuracy of the subsequent processing position.

[0044] In summary, due to the adoption of the above technical solution, a circuit board high-precision feeding device of this embodiment has the following beneficial effects compared with the prior art:

[0045] The utility model positions the circuit board and the loading seat during the circuit board feeding stage, so that subsequent processing does not need to perform inductive alignment between the processing equipment and the circuit board, thereby improving processing efficiency. The circuit board sensing point is inductively docked through the inductive platform, the circuit board is grabbed by the suction cup frame, and the position of the alignment mechanism is sensed by the sensor, so that the circuit board is transported to the specified position and accurately aligned with the loading seat, and then the circuit board is loaded. The circuit board is accurately aligned, and the loading and processing efficiency is high.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
