Description

Technical Field

[0001] The utility model relates to a device for a printed circuit board, and particularly to a positioning device for a printed circuit board. Background Art

[0002] Printed circuit boards are applied to various electronic products, such as televisions, computers, mobile phones, electronic measuring instruments, etc. With the progress of technology, printed circuit boards tend to be designed in a micro and high-density direction, making the processing process complicated. Therefore, printed circuit boards need to be moved at each processing node in the production line and will be continuously transported and conveyed in the production line. Before the printed circuit board is transported to different processing devices, the printed circuit board needs to be located at a fixed position before being moved into the processing device. The conventional method is to drive the printed circuit board to be centered and positioned by a motor. However, this method is prone to problems such as inaccurate positioning and a more complex mechanism design.

[0003] Therefore, how to improve the deficiencies of the complex design and inaccurate positioning of the conventional printed circuit board positioning mechanism is a problem that those skilled in the art urgently want to solve. Summary of the Utility Model

[0005] To achieve the above object, the utility model discloses a positioning device for a printed circuit board, including a conveying wheel set, a plurality of top support assemblies, and a guiding wheel set. The conveying wheel set includes a plurality of conveying wheels. The conveying wheels extend along a first direction and are arranged side by side in a second direction orthogonal to the first direction, and a bearing plane is defined by the first direction and the second direction. When the conveying wheels rotate, they drive a printed circuit board located on the bearing plane to move forward. Among them, the conveying wheel set has a horizontal position in which the bearing plane is parallel to a horizontal plane and an inclined position in which it rotates in the second direction and is inclined relative to the horizontal plane. The top support assembly has a body and an end located on the body. The top support assembly is vertically liftably arranged in a plurality of gaps between the plurality of conveying wheels and has a rising position located above the bearing plane and abutting against the printed circuit board. The end includes a wheel surface for the printed circuit board to laterally slide. The guiding wheel set is arranged on one side of the conveying wheel set. The guiding wheel set includes a plurality of guiding wheels arranged side by side and located above the bearing plane. Wherein, when the conveying wheel set is in the inclined position and the top support assembly is in the rising position, the printed circuit board disengages from the conveying wheels and laterally slides on the wheel surface of the end of the top support assembly and is positioned at the guiding wheels.

[0006] In one embodiment, the end is a ball.

[0039] The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the present utility model. Unless otherwise specified in the context, the singular forms "a" and "the" used herein may also include the plural forms.

[0040] The directional terms used herein, such as up, down, left, right, front, back and their derivatives or synonyms, refer to the orientation of the elements in the drawings and do not limit the present utility model, unless otherwise clearly stated in the context.

[0041] Refer to Figure 1A and Figure 1B As shown in [[REFERENCE]] and [[REFERENCE]], the present utility model discloses a positioning device 1 for a printed circuit board, especially a device for positioning a printed circuit board P in a preset orientation and position, such as horizontally arranging the printed circuit board P and making it close to or align with one side of the device 1. The positioning device 1 includes a conveying wheel set 10, a plurality of top support assemblies 20, a guide wheel set 30, a lifting member 40 and a rotating member 50. The conveying wheel set 10 is used to transport a printed circuit board P, and the guide wheel set 30 is arranged on one side of the conveying wheel set 10.

[0042] The conveying wheel set 10 includes a plurality of conveying wheels 11, and a plurality of gaps 12 are formed between the plurality of conveying wheels 11. The conveying wheels 11 extend along a first direction D1 and are arranged side by side in a second direction D2. The first direction D1 is orthogonal to the second direction D2. The conveying wheels 11 define a bearing plane P1 with the first direction D1 and the second direction D2. The printed circuit board P is placed on the bearing plane P1. When the conveying wheels 11 rotate, the bearing plane P1 drives the printed circuit board P to move in a forward direction. In this embodiment, the forward direction is the same as the second direction D2.

[0043] The top support assembly 20 has a body 21 and an end 22. The end 22 is located on the body 21. The top support assembly 20 is located in the plurality of gaps 12 between the plurality of conveying wheels 11 and is arranged on the lifting member 40. The lifting member 40 drives the top support assembly 20 to lift along a third direction D3. The third direction D3 is orthogonal to the first direction D1 and the second direction D2, that is, the third direction D3 is perpendicular to the bearing plane P1. The end 22 includes a wheel surface 221 for the printed circuit board P to slide along a lateral direction. The lateral direction is the same as the first direction D1. In this embodiment, the end 22 is a ball. Preferably, the ball is a universal ball.

[0044] The guiding wheel set 30 includes a plurality of guiding wheels 31. The guiding wheels 31 extend along the third direction D3 and are arranged side by side in the second direction D2. The guiding wheels 31 define a guiding plane P2 with the third direction D3 and the second direction D2. In this embodiment, the guiding wheels 31 and the guiding plane P2 are located above the bearing plane P1, and a bottom end 311 of the guiding wheels 31 is not higher than the bearing plane P1, so that the printed circuit board P can lean on the guiding plane P2.

[0045] The rotating member 50 can drive the conveying wheel set 10, the top support assembly 20, the guiding wheel set 30 and the lifting member 40 to rotate with the second direction D2 as an axis. In an example, the rotating member 50 drives the conveying wheel set 10, the top support assembly 20, the guiding wheel set 30 and the lifting member 40 to rotate between 10° and 50°, for example, between 20° and 40°, and preferably 30°.

[0046] Refer to Figure 2A and Figure 2B , the top support assembly 20 has a rising position (as shown in Figure 2A and Figure 2B ) that is located above the bearing plane P1 and abuts against the printed circuit board P, and a descending position (as shown in Figure 1A and Figure 1BAs shown, in this example, the lifting member 40 is disposed below the conveying wheel set 10 and drives the top support assembly 20 to lift along the third direction D3 between the raised position and the lowered position. The end portion 22 supports the printed circuit board P above the carrying plane P1 when the top support assembly 20 is in the raised position.

[0047] Referring to Figure 3 and Figure 4 , the rotating member 50 enables the conveying wheel set 10 to have a horizontal position (as shown in Figures 1A to 2B ) where the carrying plane P1 is substantially parallel to a horizontal plane, and an inclined position (as shown in Figure 3 , Figure 4 ) that is inclined with respect to the horizontal plane. When the conveying wheel set 10 is in the inclined position and the top support assembly 20 is in the raised position (as shown in Figure 3 ), the printed circuit board P detaches from the conveying wheel 11 and is on the wheel surface 221 of the end portion 22 of the top support assembly 20, and slides laterally (along the first direction D1) towards the guiding wheel set 30 and is positioned at the guiding wheel 31. After the printed circuit board P abuts against the guiding wheel set 30, the lifting member 40 drives the top support assembly 20 back to the lowered position (as shown in Figure 4 ), causing the printed circuit board P to be driven by the conveying wheel set 10 on the carrying plane P1 to move in the second direction D2.

[0048] In actual application, the positioning device 1 is connected to a processing device (not shown in the figure). The processing device may include a connecting device (not shown in the figure) having the same inclination angle as the positioning device 1 in the inclined position. The connecting device receives the printed circuit board P from the positioning device 1 into the processing device. After the printed circuit board P enters the processing device, the rotating member 50 drives the conveying wheel set 10, the top support assembly 20, the guiding wheel set 30, and the lifting member 40 to rotate, causing the carrying plane P1 of the conveying wheel set 10 to return to the horizontal position to continue receiving the next printed circuit board P.

[0049] In summary, before the printed circuit board enters the processing device, the present utility model can raise the top support assembly to the raised position by the lifting member to support the printed circuit board, and the rotating member drives the conveying wheel set, the top support assembly, the guiding wheel set, and the lifting member to rotate, enabling the printed circuit board to slide towards the guiding wheel set through the end portion of the top support assembly, thereby achieving the purpose of positioning.
