[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] An adjustable circuit board holder for transferring circuit boards, comprising:

[0027] The frame includes a transfer frame 1, which is used to transfer circuit boards. A first handle 11 is fixedly connected to the side of the transfer frame 1, which is used to facilitate the handling of circuit boards by staff.

[0028] The adjusting mechanism includes a rotating rod 2, which is rotatably connected to the surface of the transfer frame 1. The rotating rod 2 drives the active bevel gear 21 to rotate. The active bevel gear 21 is fixedly connected to the surface of the rotating rod 2, and the active bevel gear 21 drives the driven bevel gear 22 to rotate. The driven bevel gear 22 is movably connected to the surface of the active bevel gear 21, and the driven bevel gear 22 drives the lead screw 24 to rotate. A limit block 23 is fixedly connected to one side of the driven bevel gear 22, which limits the driven bevel gear 22 and the lead screw 24, allowing them to rotate only in place. The lead screw 24 is fixedly connected to the other side of the driven bevel gear 22, and the lead screw 24 drives the moving block 26 to move the extension frame 27, causing the extension frame 27 to move out of the transfer frame 1, thereby allowing the extension frame 27 to be placed... To accommodate more circuit boards, it is more convenient to transfer them in two batches without having to do so twice. A first limiting plate 25 is fixedly connected to the end of the lead screw 24 away from the driven bevel gear 22. The first limiting plate 25 is used to limit the moving block 26 and the extension frame 27, so that the moving block 26 and the extension frame 27 cannot be separated from the transfer frame 1, thus ensuring the supporting force of the extension frame 27. The moving block 26 is movably connected to the surface of the lead screw 24. The moving block 26 is used to drive the extension frame 27 to move, so that the extension frame 27 is moved out of the transfer frame 1. The extension frame 27 is fixedly connected to the surface of the moving block 26. The extension frame 27 is used to place the extra circuit boards, which is more convenient to transfer them in two batches without having to do so twice. A second handle 28 is fixedly connected to the side of the extension frame 27 away from the moving block 26. The second handle 28 is used to facilitate the workers to move the circuit boards.

[0029] The positioning mechanism includes a support plate 3, which is fixedly connected to the surface of the transfer frame 1. The support plate 3 supports the screw 31, allowing the screw 31 to drive the suction cup 34 to move downwards. The screw 31 is threadedly connected to the surface of the support plate 3, and the screw 31 drives the suction cup 34 to move downwards, creating a negative pressure between the suction cup 34 and the tabletop, causing it to adhere to the tabletop. A movable plate 32 is fixedly connected to the lower end of the screw 31. The movable plate 32 ensures that the rotation of the screw 31 does not affect the second limiting plate 33 and the suction cup 34. The surface of the movable plate 32 is movable. A second limiting plate 33 is dynamically connected, and a suction cup 34 is fixedly connected to the lower surface of the second limiting plate 33. The suction cup 34 is used to create negative pressure between itself and the table, adsorbing onto the table, thereby increasing the friction between the device and the table, making the device stable on the table, and reducing the occurrence of accidental tipping and damage to the circuit board. A limiting rod 35 is fixedly connected to the lower surface of the support plate 3. The second limiting plate 33 and the limiting rod 35 are used to limit the suction cup 34, so that the suction cup 34 will not rotate with the rotation of the screw 31.

[0030] Furthermore, the rotating rod 2 is used to drive the active bevel gear 21 to rotate. The active bevel gear 21 is rotatably connected to the transfer frame 1 through the rotating rod 2. The active bevel gear 21 is used to drive the driven bevel gear 22 to rotate. The driven bevel gear 22 is rotatably connected to the transfer frame 1 through the active bevel gear 21. The driven bevel gear 22 is used to drive the lead screw 24 to rotate.

[0031] Furthermore, the limiting block 23 is composed of two cylinders with different radii. The limiting block 23 is rotatably connected to the driven bevel gear 22 and the transfer frame 1. The limiting block 23 is used to limit the driven bevel gear 22 and the lead screw 24, so that the driven bevel gear 22 and the lead screw 24 can only rotate in place.

[0032] Furthermore, the lead screw 24 is rotatably connected to the transfer frame 1 via the driven bevel gear 22. The lead screw 24 is used to drive the moving block 26 to move the extension frame 27, so that the extension frame 27 is moved out of the transfer frame 1, thereby allowing more circuit boards to be placed without having to transfer them in two batches, which is more convenient. The first limiting plate 25 is in the shape of a circular plate. The first limiting plate 25 is used to limit the moving block 26 and the extension frame 27, so that the moving block 26 and the extension frame 27 cannot be separated from the transfer frame 1, thus ensuring the supporting force of the extension frame 27.

[0033] Furthermore, the movable block 26 is block-shaped, and the movable block 26 and the extension frame 27 are slidably connected to the transfer frame 1 through the lead screw 24. The movable block 26 is used to drive the extension frame 27 to move, so that the extension frame 27 is moved out of the transfer frame 1. The surface of the extension frame 27 is provided with a circular groove to accommodate the lead screw 24 and the first limiting plate 25. The extension frame 27 is used to place the extra circuit board, which does not need to be transferred in batches, making it more convenient. The second handle 28 is used to facilitate the workers to move the circuit board.

[0034] Furthermore, the support plate 3 is plate-shaped, and the support plates 3 are symmetrically distributed in two sets on the surface of the transfer frame 1. The support plate 3 is used to support the screw 31, so that the screw 31 can drive the suction cup 34 to move downward. The screw 31 is used to drive the suction cup 34 to move downward, so that a negative pressure is formed between the suction cup 34 and the table, and it is adsorbed on the table. The movable plate 32 is circular plate-shaped, and the movable plate 32 is used to ensure that the rotation of the screw 31 does not affect the second limiting plate 33 and the suction cup 34.

[0035] Furthermore, the second limiting plate 33 is plate-shaped and is slidably connected to the limiting rod 35 via the screw 31 and the movable plate 32. The suction cup 34 is used to create negative pressure between itself and the table, adhering to the table to increase the friction between the device and the table, making the device stable on the table and reducing the possibility of accidental tipping and damage to the circuit board. The limiting rod 35 is round and passes through the second limiting plate 33. The second limiting plate 33 and the limiting rod 35 are used to limit the suction cup 34, preventing the suction cup 34 from rotating with the screw 31.

[0036] Working principle: When there are more circuit boards, rotating the rotating rod 2 drives the active bevel gear 21 to rotate, which in turn drives the driven bevel gear 22 and the lead screw 24 to rotate. This drives the moving block 26 to move the extension frame 27, so that the extension frame 27 is moved out of the transfer frame 1. This allows more circuit boards to be placed without having to transfer them in two batches, which is more convenient.

[0037] After placing the device on the table, rotating the screw 31 can drive the suction cup 34 to move down, creating a negative pressure between the suction cup 34 and the table, thus adhering it to the table. This increases the friction between the device and the table, making the device stable on the table and reducing the possibility of accidental tipping and damage to the circuit board.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
