Description

A PCB board positioning component

Technical Field

The utility model belongs to the technical field of electronic component processing, in particular to a PCB board positioning component.

Background Art

Sheet-shaped electronic components such as PCB boards and semiconductor chips are small in size and thin in thickness. When processing such electronic components, they need to be clamped and fixed first, and then subsequent processing can be performed after they are fixed. For example, in the wire bonding process of a PCB board, one surface of the PCB board needs to be processed. At this time, the PCB board needs to be fixed, and the fixing structure is required not to block the surface of the PCB board to ensure that the processing will not be blocked. Therefore, the commonly used fixing method in the prior art is to press the PCB board from the side to achieve the fixing effect.

However, the side surfaces of electronic components such as PCB boards also have low processing precision, and there are structures such as protrusions or grooves on the side surfaces of electronic components, making the side surfaces of electronic components uneven. When a pressing structure such as a push block is used to fix from the side, it is very likely that the pressing surface of the push block will abut against the protruding structure on the side surface of the electronic component. If the pressing surface abuts against the protruding structure, the contact area between the pressing surface and the PCB board is very small. When the PCB board is processed, the PCB board is easily moved by the force, thereby causing production accidents or damage to the PCB board.

Utility Model Content

The utility model aims to provide a PCB board positioning assembly, which is used to solve the problem that the uneven side of the electronic component leads to unstable fixation, resulting in production accidents or damage to the PCB board.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

A PCB board positioning assembly includes a positioning unit, the positioning unit includes a slide groove and a pushing block, the pushing block is slidably connected to the slide groove, the end of the slide groove and the pushing block are respectively provided with a first fixing surface and a second fixing surface, the first fixing surface and the second fixing surface are used to fix the PCB board from both sides, sliding the pushing block is used to change the distance between the first fixing surface and the second fixing surface, and the first fixing surface and the second fixing surface are provided with grooves.

In this solution, grooves are respectively provided on the first fixing surface and the second fixing surface. When the first fixing surface and the second fixing surface are used to fix the PCB board, the first fixing surface and the second fixing surface are respectively pressed against the two sides of the PCB board, and then the PCB board is pushed back and forth along the direction of the first fixing surface or the second fixing surface. When the PCB board is pushed back and forth, if there is a protruding structure on the side of the PCB board, the protruding structure will enter the groove during the pushing process, so that the distance between the first fixing surface and the second fixing surface is reduced again. By accommodating the protruding structure on the side by the groove, the first fixing surface and the second fixing surface have more contact points with the PCB board, and the stability of fixing the PCB board is improved by increasing the contact points and the contact area. The more contact points the first fixing surface and the second fixing surface have with the PCB board, the more stable the fixing effect of the PCB board is, thereby avoiding displacement of the PCB board during processing, avoiding production accidents and damage to the PCB board.

Preferably, the length direction of the groove is perpendicular to the board surface of the fixed PCB board.

In this solution, the PCB is fixed by abutting the sides of the PCB with the two sides of the groove opening. In this processing method of the groove, the upper and lower sides of the groove can pass through the push block, or the groove can pass through the push block from the upper side or the lower side, which facilitates the processing of the groove and reduces the processing difficulty.

In order to solve the problem of small groove coverage, the first fixing surface and the second fixing surface are respectively provided with at least one groove.

In this solution, at least one groove is set on one surface, and multiple grooves may also be set. The coverage area of the grooves can be increased by increasing the number of grooves, so that the first fixing surface and the second fixing surface can adapt to the protruding structures at various locations of the PCB board.

Preferably, a spring is provided between the slide groove and the pushing block, and two ends of the spring are respectively connected to the pushing block and the slide groove.

In this solution, the spring provides continuous pressure to the push block, so that the first fixing surface and the second fixing surface can continuously press the PCB board, so that the PCB board can be stably fixed.

Preferably, the groove is divided into an arc groove, a U-shaped groove, a rectangular groove or a V-shaped groove according to the cross-sectional shape, and the groove is any one of the arc groove, U-shaped groove, rectangular groove or V-shaped groove or a combination of any two or more thereof.

In this solution, the groove structure is used to accommodate the protruding structure. Since the size of the protruding structure will not be large even if the processing accuracy of the PCB board side is low, the structure of the groove can be flexibly selected and only needs to be able to accommodate the protruding structure.

Preferably, the first fixing surface is provided with an arc-shaped groove, and the second fixing surface is provided with at least two grooves.

In this solution, the first fixing surface is provided with an arc groove, and the two sides of the opening of the arc groove abut against one side of the PCB board, and there are two contact points with the side of the PCB board, and the second fixing surface is provided with at least two grooves, and there are at least three contact points with the side of the PCB board. It is thought that the first fixing surface abuts against two corners of the PCB board, and the second fixing surface abuts against multiple points on the side of the PCB board.

Preferably, the positioning assembly includes at least two positioning units.

In this solution, at least two positioning units are provided to fix at least two PCB boards at the same time, so that the PCB boards can be processed in batches at one time, thereby improving the processing efficiency.

The utility model has the following beneficial effects:

The utility model provides grooves on the first fixing surface and the second fixing surface for fixing the PCB board, and the grooves can accommodate the protruding structures on the side surfaces of the PCB board, so that the protruding structures will not be pressed when the first fixing surface and the second fixing surface press the side surfaces of the PCB board, thereby ensuring the contact areas between the first fixing surface, the second fixing surface and the PCB board, improving the stability of fixing the PCB board, thereby preventing the PCB board from being displaced when being processed, and avoiding production accidents and damage to the PCB board.
