The first clamping frame and the second clamping frame have identical structures and are symmetrically arranged on the rotating frame. The first clamping frame has mounting plates symmetrically arranged vertically. A limit block is fixedly mounted on one side of the mounting plate, and a movable moving plate is provided on the other side.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Referring to Figures (1-4), a flexible circuit board production auxiliary fixture includes a clamping platform 1, a rotating frame 13 rotatably mounted on the clamping platform 1, and a first clamping frame 2 and a second clamping frame 3 rotatably mounted on the rotating frame 13. The first clamping frame 2 and the second clamping frame 3 have the same structure and are symmetrically arranged on the rotating frame 13. The first clamping frame 2 is symmetrically arranged with mounting plates 4 on its upper and lower sides. A limit block 6 is fixedly mounted on one side of the mounting plate 4, and a movable moving plate 5 is provided on the other side. A moving rod 51 is mounted on the moving plate 5. One end of the moving rod 51 is connected to the moving plate 5, and the other end passes through the mounting hole 41 opened on the mounting plate 4 and is provided with a suction cup 52.

[0018] The clamping platform 1 has a rotating groove 11, and the rotating frame 13 is rotatably mounted on the rotating groove 11. The center of the side of the rotating frame 13 is connected to the output end of the first motor 12 located inside the clamping platform 1 via a rotating shaft. The first clamping frame 2 is provided with an electric push rod 54, and the telescopic end of the electric push rod 54 is connected to the moving plate 5.

[0019] The first clamping frame 2 and the second clamping frame 3 are respectively provided with a first side gear 21 and a second side gear 31 on both sides. The first side gear 21 and the second side gear 31 mesh with each other. The center of the outer side wall of the first side gear 21 is connected to the output end of the second motor 7 mounted on the rotating frame 13 through a rotating shaft. A vacuum pump 8 is installed on the first clamping frame 2. The moving rod 51 has a pipe inside that communicates with the suction cup 52, and the pipe is connected to the vacuum pump 8 through an air pipe. The moving plate 5 has a screw hole 53, and the bottom of the moving rod 51 has a threaded groove. The moving rod 51 is connected to the moving plate by bolts passing through the screw hole 53 and screwing into the groove at the bottom of the moving rod 51.

[0020] The operating procedure for this device is as follows: Figure 4 As shown in the diagram, the rectangles with triangles indicate the flexible circuit boards placed on the clamping frames. The triangles point to indicate the orientation of the flexible circuit boards. The rotating frame, the first clamping frame, and the second clamping frame are depicted in a simplified manner and do not represent their actual structures. The specific process is as follows:

[0021] 1. After the circuit board is placed on the limiting block 6 on the top mounting plate 4 and is attracted by the suction cup, the front of the circuit board can be operated.

[0022] 2. After the operation on the front of the circuit board is completed, the second motor 7 drives the first clamping frame 2 to rotate 180 degrees, and the second clamping frame 3 rotates 180 degrees accordingly. After the rotation, the second circuit board is placed on the limiting block 6 of the newly rotated mounting plate 4 and is attracted and operated on the front of the second circuit board. At the same time, the first circuit board is pushed into the mounting plate 4 on the second clamping frame 3 and attracted by the electric push rod. At the same time, the attraction of the first clamping frame 2 to it is released.

[0023] 3. Control the second motor 7 to drive the first clamping frame 2 to rotate 180 degrees, and the second clamping frame 3 to rotate 180 degrees accordingly, so that the first circuit board and the second circuit board are rotated to the bottom of the second clamping frame and the first clamping frame respectively;

[0024] 4. Transfer the second circuit board on the first clamp 2 (the specific transfer method is described in detail in step 2) to the upper mounting plate of the second clamp;

[0025] 5. Start the first motor 12 to rotate the rotating frame 13 180 degrees and rotate the second clamping frame 3 above the rotating frame 13. At this time, the back of the first circuit board on the mounting plate above the second clamping frame 3 can be operated.

[0026] 6. The first clamping frame 2 is rotated 180 degrees by the second motor 7, and the second clamping frame 3 is rotated 180 degrees accordingly. After the first circuit board is rotated to the bottom of the second clamping frame 3, it is transferred to the mounting plate above the first clamping frame 2 for adsorption. The second circuit board is rotated to the top of the second clamping frame 3, and the back of the second circuit board is operated.

[0027] 7. The second motor 7 drives the first clamping frame 2 to rotate 180 degrees, and the second clamping frame 3 follows suit and rotates 180 degrees, so that the second circuit board rotates to the bottom of the second clamping frame 3 and the first circuit board rotates to the bottom of the first clamping frame.

[0028] 8. Release the first circuit board from the suction, allowing it to fall onto the conveyor belt located below the device for transport or be temporarily collected in another collection device; at the same time, transfer the second circuit board located below the second clamping frame 3 to the mounting plate above the first clamping frame for suction; place the third circuit board on the mounting plate above the second clamping frame 3 and operate on the front of the third circuit board.

[0029] 9. The second motor 7 drives the first clamping frame 2 to rotate 180 degrees, and the second clamping frame 3 follows suit and rotates 180 degrees, so that the second circuit board rotates to the bottom of the first clamping frame 3, the third circuit board rotates to the bottom of the second clamping frame 2, and the fourth circuit board is attached to the mounting plate 4 above the second clamping frame 2.

[0030] 10. The contact with the adsorption of the second circuit board causes it to fall, while simultaneously transferring the third circuit board below the second clamping frame 3 to the top of the first clamping frame 2.

[0031] The subsequent steps 11 to 18 repeat the steps 3 to 10 above, to achieve the flipping operation of the front and back of the circuit board.

[0032] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
