Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, specifically to a PCB board horizontal positioning mechanism. Background Technology

[0002] A PCB, also known as a printed circuit board, is both a support for electronic components and a carrier for the electrical connection lines of those components. Almost all electronic devices, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, use PCBs to enable electrical interconnection between various components.

[0003] To adapt to different application scenarios, PCBs come in various shapes, such as square, rectangular, and round. During the production process, the PCBs need to be horizontally positioned for processing or debugging. Traditional positioning methods mostly involve setting positioning protrusions on adjacent sides and then using top plates in the X and Y directions to press against the side walls of the PCBs, thus securing them to the positioning protrusions for positioning. This method requires two power sources in the X and Y directions for driving, resulting in a complex structure, high cost, and poor synchronization of actions. Utility Model Content

It has a first inclined surface that contacts the lower end of the first push block, with its contact line extending along the X direction, and a second inclined surface that contacts the lower end of the second push block, with its contact line extending along the Y direction. When the drive plate moves up or down, the first push block and the second push block rotate through the first inclined surface and the second inclined surface, respectively, so that the upper ends of the first push block and the upper ends of the second push block, together with the first protrusion and the second protrusion, abut against the four side walls of the PCB board to achieve horizontal positioning.

[0006] Preferably, the first push block is rotatably connected to the side wall of the support platform parallel to the X direction, and the second push block is rotatably connected to the side wall of the support platform parallel to the Y direction.

[0024] like Figures 1 to 7 As shown, the PCB board horizontal positioning mechanism provided by this utility model includes: a support platform 10 for placing the PCB board 1, positioning protrusions, push blocks, and a drive plate 40 disposed on the support platform 10. The positioning protrusions include a first protrusion 21 that flattens against the PCB board 1 along the X direction and a second protrusion 22 that flattens against the PCB board 1 along the Y direction. The push blocks include a first push block 31 disposed on the side opposite to the first protrusion 21 and a second push block 32 disposed on the side opposite to the second protrusion 22. The first push block 31 and the second push block 32 are rotatably disposed, with the rotation axis of the first push block 31 extending along the X direction and the rotation axis of the second push block 32 extending along the Y direction. The drive plate 40 is movably disposed on the support platform 10. On one side, there is a first inclined surface 41 that contacts the lower end of the first push block 31. The contact line between the first inclined surface 41 and the first push block 31 extends along the X direction. There is also a second inclined surface 42 that contacts the lower end of the second push block 32. The contact line between the second inclined surface 42 and the second push block 32 extends along the Y direction. The angles between the first inclined surface 41, the second inclined surface 42 and the horizontal plane are equal. When the drive plate 40 moves downward, the first push block 31 and the second push block 32 rotate through the first inclined surface 41 and the second inclined surface 42 respectively, so that the upper end of the first push block 31 and the upper end of the second push block 32, together with the first protrusion 21 and the second protrusion 22, abut against the four side walls of the PCB board 1 to achieve horizontal positioning.

[0025] The advantage of this setup is that only a single power source is needed to drive the drive plate 40 to move up and down, resulting in a simple structure, low cost, and good synchronization of movements.

[0026] The power source is a cylinder. Specifically, the PCB board horizontal positioning mechanism also includes a drive cylinder 50 that drives the drive plate 40 to move up and down. The drive cylinder 50 is fixed to the bottom of the support platform 10.

[0027] In this embodiment, the first push block 31 is rotatably connected to the first lug 11 on the side wall of the support platform 10 parallel to the X direction. The side wall is also provided with a first spring 311 that drives the first push block 31 to rotate and a first groove 12 that accommodates the end of the first spring 311. The two ends of the first spring 311 abut against the bottom wall of the first push block 31 and the first groove 12, respectively. The first spring 311 has the tendency to drive the first push block 31 to rotate so that its upper end abuts against the side wall of the PCB board 1. The second push block 32 is rotatably connected to the second lug 13 on the side wall of the support platform 10 parallel to the Y direction. The side wall is also provided with a second spring 321 that drives the second push block 32 to rotate and a second groove 14 that accommodates the end of the second spring 321. The two ends of the second spring 321 abut against the bottom wall of the second push block 32 and the second groove 14, respectively. The second spring 321 has the tendency to drive the second push block 32 to rotate so that its upper end abuts against the side wall of the PCB board 1.

[0028] The advantage of this setting is that the first push block 31 and the second push block 32 are in the default state of pressing against the side wall of the PCB board 1, so that the PCB board 1 can still be positioned when the drive cylinder 50 fails.

[0029] To facilitate transmission and adjustment, in this embodiment, the lower end of the first push block 31 is connected to a first transmission column 312 extending in the X direction. The outer wall of the first transmission column 312 abuts against the first inclined surface 41 to achieve line contact. The lower end of the second push block 32 is connected to a second transmission column 322 extending in the Y direction. The outer wall of the second transmission column 322 abuts against the second inclined surface 42 to achieve line contact. Further, the drive plate 40 is movably connected to the top of the drive cylinder 50. The driving plate 40 moves in the X direction. The drive plate 40 is provided with a first drive block 43 and a second drive block 44 spaced apart. The first inclined surface 41 is located at the end of the first drive block 43 facing the first push block 31, and the second inclined surface 42 is located at the end of the second drive block 44 facing the second push block 32. The first drive block 43 is movably connected to the drive plate 40. The moving direction of the first drive block 43 is the Y direction.

[0030] In this embodiment, the PCB board 1 is a long strip PCB board. During positioning, if the first push block 31 and the second push block 32 are extremely close, the PCB board 1 is prone to bending, affecting the positioning accuracy. In severe cases, it may even damage the PCB board 1. To solve this problem, there are two first push blocks 31 and they are spaced apart along the X direction. The first transmission column 312 on the two first push blocks 31 are connected as one unit. At the same time, there are also multiple first protrusions 21 spaced apart along the X direction. In order to realize the detection linkage, the support platform 10 is further provided with a sensor 15 for detecting the presence or absence of the PCB board 1. The sensor 15 is located between the two first push blocks 31.

[0031] To facilitate the adsorption of the PCB board 1, in this embodiment, a number of magnetic pillars 16 are embedded on the upper surface of the support platform 10.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
