Description

PCB welding jig

Technical Field

The utility model belongs to the technical field of welding jigs, and particularly relates to a PCB welding jig.

Background

The PCB board, called a printed circuit board, is an important electronic component, is a support for electronic components, and is a carrier for electrical interconnection of the electronic components. It is called a "printed" circuit board because it is made using electronic printing.

In the process of processing a PCB, for example, when pins of an electronic component are soldered to the PCB, a cold joint phenomenon is easily generated, thereby resulting in poor soldering quality. The applicant has analyzed and studied that this is mainly caused by the fact that the PCB board which is not effectively fixed during the soldering process is offset.

For example, the publication number is CN211267299U, the utility model is a chinese patent of a PCB board welding carrier, and only a friction pad is used to prevent the PCB board from sliding and shifting during welding, so that the practicality and reliability are low, and therefore, it is highly desirable to improve the fixing effect on the PCB board.

Disclosure of Invention

Aiming at the technical problems in the prior art, the utility model provides a PCB welding jig.

The technical scheme for solving the technical problems is as follows:

the utility model provides a PCB board welding jig, includes the mounting panel, the symmetry is provided with the fixed frock and the removal frock that are used for pressing from both sides tight PCB board on the mounting panel, but remove the frock and remove the fixed frock removal relatively, all be provided with the dog that is used for supporting the PCB board on fixed frock and the removal frock.

On the basis of the technical scheme, the utility model can be improved as follows.

Further, be provided with drive assembly on the mounting panel, drive assembly includes fixing base and cylinder, the cylinder body of cylinder passes through fixing base fixed connection mounting panel, the one end fixed connection removal frock of its cylinder body is kept away from to the piston rod of cylinder.

Further, be provided with main shaft and a plurality of guiding axle on the removal frock, remove the piston rod fixed connection of frock through main shaft and cylinder, the guiding axle is on a parallel with the piston rod setting of cylinder, be provided with the linear bearing with guiding axle looks adaptation on the fixing base.

Further, the number of the guide shafts is two, and the guide shafts are symmetrically arranged on two sides of the main shaft.

The beneficial effects of the utility model are as follows: the utility model has simple structure, good practicability and working reliability, can effectively fix the PCB, and ensures that the PCB is always kept at a horizontal position, thereby improving the welding quality of the PCB.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

Example 1

As shown in fig. 1, a PCB board welding jig of this embodiment includes a mounting plate 1, the symmetry is provided with a fixed tooling 2 and a movable tooling 3 for clamping the PCB board on the mounting plate 1, the movable tooling 3 can move relative to the fixed tooling 2, and the fixed tooling 2 and the movable tooling 3 are both provided with a stop block 4 for supporting the PCB board.

By adopting the scheme, after the PCB to be welded is placed between the fixed tool 2 and the movable tool 3, the movable tool 3 moves towards the direction of the fixed tool 2 to clamp the PCB, so that the PCB is effectively fixed. In addition, through setting up dog 4, can prevent effectively that the removal frock 3 from keeping away from fixed frock 2 the PCB board takes place vertical great displacement and fall even the board under self action of gravity to when protecting the PCB board, ensure that the PCB board remains in horizontal position all the time, further improve the practicality and the operational reliability of PCB board welding jig and the welding quality of PCB board.

Example 2

The structure of this embodiment is substantially similar to that of embodiment 1, except that a drive assembly 5 is also provided.

As shown in fig. 1-2, a driving assembly 5 is arranged on the mounting plate 1, the driving assembly 5 comprises a fixing seat 51 and an air cylinder 52, a cylinder body of the air cylinder 52 is fixedly connected with the mounting plate 1 through the fixing seat 51, and one end, far away from the cylinder body, of a piston rod of the air cylinder 52 is fixedly connected with the moving tool 3.

By adopting the scheme, the movable tool 3 is controlled to be close to or far away from the fixed tool 2 through the air cylinder 52, so that the operation is simple and convenient, and the operation stability and the working reliability are high.

On the basis of the technical scheme, the movable tool 3 is provided with a main shaft 53 and a plurality of guide shafts 54, the movable tool 3 is fixedly connected with a piston rod of the air cylinder 52 through the main shaft 53, the guide shafts 54 are parallel to the piston rod of the air cylinder 52, and the fixed seat 51 is provided with a linear bearing 55 matched with the guide shafts 54.

Through the guide shaft 54 that adds, carry out effective spacing and direction to the direction of movement of removing frock 3, further improve PCB board welding jig's operation stability and operational reliability.

The number of the guide shafts 54 in this embodiment is two, and the guide shafts are symmetrically disposed on two sides of the main shaft 53, so as to further ensure that the moving tool 3 moves stably.

In the present utility model, the devices and components not described in the structure are all commercially available devices or components.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
