For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood in combination with specific situations.

[0034] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] This embodiment relates to a circuit board flipping device. In terms of the overall structure, as Figure 1 and Figure 2 shown, it includes a workbench 1, a sliding mechanism 3, a flipping mechanism 4, and an abutting mechanism 5.

[0036] Among them, a through hole 2 is opened on the top surface of the workbench 1, the sliding mechanism 3 is fixedly arranged at the through hole 2, the flipping mechanism 4 is fixedly arranged on the sliding mechanism 3 and moves along with the sliding mechanism 3, the circuit board is fixedly arranged on the flipping mechanism 4, and there are multiple abutting mechanisms 5 which are oppositely arranged on the flipping mechanism 4, and the circuit board is clamped by two opposite abutting mechanisms 5.

[0037] It is worth mentioning that a dispensing device is installed on the workbench 1, and the dispensing device dispenses glue on the circuit board on the flipping mechanism 4. The dispensing device is a common cross-sliding device, which will not be elaborated here. The through hole 2 opened on the workbench 1 is for installing the sliding mechanism 3 to ensure that the sliding mechanism 3 and the workbench 1 are horizontal. The flipping mechanism 4 moves along with the sliding mechanism 3 and cooperates with the cross-sliding device of the dispensing device, so as to achieve three-dimensional sliding and ensure that glue is dispensed at each position of the circuit board. The flipping mechanism 4 can drive the circuit board to flip by 180°. That is to say, after one side of the circuit board is dispensed with glue, the other side of the circuit board is dispensed with glue through the flipping mechanism 4, so as to realize double-sided dispensing of the circuit board. Multiple abutting mechanisms 5 can clamp the circuit board on the flipping mechanism 4 to ensure that the circuit board will not tilt or fall during glue dispensing, thereby improving the glue dispensing quality.

[0038] Based on the above overall introduction, an exemplary structure of the circuit board flipping device of this embodiment is as Figure 2 and Figure 3As shown in the figure, the sliding mechanism 3 includes a housing 301 fixedly arranged on the workbench 1, a lead screw 302 rotatably arranged in the housing 301, and a slider 303 screwed onto the lead screw 302. The slider 303 is fixedly connected to the cross plate 401. Specifically, the housing 301 is fixedly installed at the through port 2 on the workbench 1. The slider 303 reciprocally slides along the length direction of the through port 2, thereby driving the flipping mechanism 4 to move. Both ends of the lead screw 302 are rotatably connected to both ends of the housing 301 through bearings. One end of the lead screw 302 extends out of the housing 301 and is driven by a stepping motor. The lead screw 302 is screwed to the slider 303, thereby realizing the lead screw 302 driving the slider 303 to move.

[0039] As a preferred implementation manner, as Figure 4 shown, in this embodiment, the flipping mechanism 4 includes a cross plate 401 fixedly arranged on the sliding mechanism 3, two vertical plates 402 arranged on the cross plate 401, and a flipping frame 403 rotatably arranged between the two vertical plates 402. The circuit board is arranged in the flipping frame 403. It should be noted that the cross plate 401 is fixedly installed on the slider 303, thereby realizing the cross plate 401 following the slider 303 to move. The two vertical plates 402 are arranged oppositely. The flipping frame 403 is square. Both ends of the flipping frame 403 are rotatably connected to the columns. The circuit board is located inside the square flipping frame 403. When the flipping frame 403 rotates, it drives the circuit board to flip.

[0040] Preferably, as Figure 5 shown, in this embodiment, mounting plates 404 are respectively fixedly arranged at both ends of the flipping frame 403. A groove 405 is formed on the flipping frame 403. The mounting plates 404 are located in the groove 405. A rotating shaft 406 extends outward from the middle of the mounting plate 404. The rotating shaft 406 is connected to the vertical plate 402 through a bearing. Specifically, the mounting plate 404 and the groove 405 have the same shape. The mounting plate 404 is fixedly installed in the groove 405. The setting of the groove 405 ensures that the mounting plate 404 does not protrude from the flipping frame 403, ensuring that the circuit board and the mounting plate 404 do not affect each other. The rotating shaft 406 extends out of the flipping frame 403. The vertical frame can support the rotating shaft 406, ensuring the horizontal flipping of the flipping frame 403 and facilitating the dispensing equipment to perform dispensing.

[0041] Preferably, as Figure 5 and Figure 6 shown, through holes 407 are oppositely formed on both sides of the flipping frame 403 in this embodiment. The abutting mechanism 5 is inserted into the through holes 407. A through groove 408 is formed on one side of the through hole 407 of the flipping frame 403. A driving motor 409 is fixedly arranged on the vertical plate 402. After one of the rotating shafts 406 extends out of the vertical plate 402, it is fixedly connected to the driving shaft of the driving motor 409.

[0042] Specifically, the number of abutting mechanisms 5 is the same as the number of through holes 407. One abutting mechanism 5 is installed in one through hole 407, and the abutting mechanism 5 abuts against the circuit board. Since the through holes 407 are oppositely arranged on the turnover frame 403, the two opposite abutting mechanisms 5 can clamp the circuit board, thereby realizing the fixation of the circuit board. The setting of the through groove 408 facilitates the installation of the circuit board. Since the four surfaces of the circuit board are parallel to the four surfaces of the turnover frame 403, if the circuit board is too large and the gap between it and the turnover frame 403 is small, it is inconvenient to place the circuit board in the turnover frame 403. The opened through groove 408 can expand the gap between the wall of the turnover frame 403 and the circuit board, thus facilitating the installation of the circuit board in the turnover frame 403. The driving motor 409 is fixedly installed on one of the vertical plates 402, and the rotating shaft 406 on this vertical plate 402 extends out of the vertical plate 402, thereby realizing the driving motor 409 driving the turnover frame 403 to rotate.

[0043] As a preferred embodiment, as Figure 7 shown, in this embodiment, the abutting mechanism 5 includes a sleeve 501 fixedly arranged in the through hole 407, a nut 502 fixedly arranged on the sleeve 501, and a support rod 503 inserted into the nut 502, and the nut 502 and the support rod 503 are screwed together. It should be noted that the sleeve 501 is fixedly installed in the through hole 407, and the support rod 503 slides in the sleeve 501 until it abuts against the circuit board and clamps the circuit board. The nut 502 is concentric with the sleeve 501 and fixedly connected to the sleeve 501. Since the support rod 503 and the nut 502 are screwed together, the support rod 503 can stay at any position to ensure that circuit boards of different sizes can be fixed.

[0044] Preferably, still as Figure 7 shown, a round hole 504 is opened on the support rod 503 of this embodiment, a ejector rod 505 is telescopically arranged in the round hole 504, a fixed block 506 is fixedly arranged on the ejector rod 505, and a bearing groove 507 is opened on the fixed block 506. The circuit board is placed in the bearing groove 507. A spring 508 is arranged between the fixed block 506 and the support rod 503.

[0045] Specifically, the round hole 504 is opened at one end of the support rod 503 for the ejector rod 505 to telescopically move. The ejector rod 505 and the fixed block 506 are integrally formed. The circuit board is placed in the bearing groove 507, which can improve the fixing strength of the circuit board and prevent the circuit board from tilting during dispensing. One end of the spring 508 abuts against the fixed block 506, and the other end abuts against the support rod 503. When the support rod 503 moves towards the circuit board, since the fixed block 506 abuts against the circuit board, the spring 508 is compressed, which can improve the clamping strength of the circuit board and also improve the buffering force between the fixed block 506 and the circuit board, better protecting the circuit board from being damaged by clamping.

[0046] In the circuit board flipping device of this embodiment, through the setting of the sliding mechanism 3, it is ensured that the circuit board can slide, which is convenient for cooperating with the dispensing machine for dispensing, improving the automation of the equipment. Through the setting of the flipping mechanism 4, it is ensured that the circuit board can be flipped, realizing automatic flipping and dispensing on both sides of the circuit board. Through the setting of the abutting mechanism 5, it is convenient for the circuit board to be fixed on the flipping mechanism 4, avoiding the circuit board from tilting and falling. Through the setting of the through groove 408, it is convenient for the circuit board to be disassembled and assembled on the flipping mechanism 4.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
