Description

Technical Field

[0001] The utility model relates to the field of electronic components, and particularly relates to a welding jig for electronic components. Background Art

[0002] In the production process of a PCB board, electronic components need to be welded on a substrate. Therefore, a welding jig is required to fix the electronic components and the substrate, limit the relative movement of the positions between the electronic components and the substrate, and facilitate the welding of the electronic components.

[0003] A Chinese patent discloses a welding jig for electronic components (authorization publication number CN 215034815 U). This patented technology can solve the problems that the grooves opened on the upper template are too large, which easily causes the electronic components to shake, and if the grooves opened on the upper template are too small, it is easy to cause the electronic components to be unable to be placed in the grooves, and has the characteristics of poor fixing effect.

[0004] During the welding process of the existing PCB board, welding slag is easily generated, and there is a lack of a cleaning structure for it. Moreover, there is a lack of an inspection structure after welding, so it is impossible to ensure that all parts of the electronic components and the PCB board are welded completely.

On the left and right side walls of the workbench, limiting clips are symmetrically installed. The limiting clips are connected to the upper frames in a sliding fit manner. On the rear end surface of the base table, a base is installed. On the upper end surface of the base, an adjusting motor is installed. On the output end of the adjusting motor, an adjusting cam is installed. Below the adjusting cam, a U-shaped plate is arranged.

[0006] Preferably: A camera is installed at the bottom of the U-shaped plate, and a display screen is installed on the rear end surface of the base. The camera is electrically connected to the display screen.

[0007] Preferably: Fixing rods are symmetrically installed on the front and rear of the upper end surface of the base frame. The fixing rods are connected to the base frame in a sliding fit manner.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4, in this embodiment, an electronic component welding jig is provided, which includes a bottom table 1 and a workbench 2. On the upper end surface of the bottom table 1, bottom frames 11 are symmetrically installed on the left and right. On the upper end surface of the bottom frame 11, spring rods 12 are installed. On the upper end surface of the spring rod 12, an upper frame 14 is installed. The inner end of the upper frame 14 is rotatably installed with a workbench 2 through a bearing. On the left and right side walls of the workbench 2, limit clips 13 are symmetrically installed. The limit clips 13 are connected to the upper frame 14 in a sliding fit manner. On the rear end surface of the bottom table 1, a base 15 is installed. On the upper end surface of the base 15, an adjustment motor 16 is installed. The output end of the adjustment motor 16 is installed with an adjustment cam 17. A U-shaped plate is arranged at the bottom of the adjustment cam 17. During operation, the PCB board is placed on the workbench 2 for welding processing. The limit clips 13 play a limiting role on the workbench 2, driving the outer end of the limit frame to move. The workbench 2 is rotated 180 degrees so that the PCB board faces downward. The adjustment motor 16 is started to drive the adjustment cam 17 to rotate, driving the upper frame 14 to move up and down through the spring rod 12, so as to be able to clean the welding slag on the surface of the PCB board and detect the welding effect between the PCB board and the electronic components. Components that are not welded well will fall off, avoiding welding mistakes.

[0021] A camera 18 is installed at the bottom of the U-shaped plate. A display screen 19 is installed on the rear end surface of the base 15. The camera 18 is electrically connected to the display screen 19. During operation, after the welding slag is cleaned, the workbench 2 is reset. The camera 18 takes pictures of the surface condition of the PCB board. The staff can view the surface condition of the PCB board through the display screen 19, which is convenient for its maintenance and repair.

[0022] Fixing rods 21 are symmetrically installed on the front and rear of the upper end surface of the bottom frame 11. The fixing rods 21 are connected to the bottom frame 11 in a sliding fit manner. During operation, the fixing rods 21 play a supporting role on the upper frame 14 to ensure the stability of the workbench 2 during operation. When driving the upper frame 14 to move up and down, the fixing rods 21 are moved outward, losing the supporting effect on the upper frame 14.

[0023] A first chuck 22 is installed at the inner end of the limit clip 13. The first chuck 22 is connected to the outer end of the upper frame 14 in a clamping manner. During operation, the first chuck 22 limits and fixes the limit clip 13 to prevent the limit clip 13 from sliding relative to the upper frame 14.

[0024] Clamping frames 23 are symmetrically installed on the front and rear of the upper end surface of the workbench 2. During operation, the clamping frames 23 limit and fix the PCB board to ensure the stability of the PCB board during operation.

[0025] A recycling box 24 is arranged below the workbench 2. The recycling box 24 is installed on the upper end surface of the bottom table 1. During operation, the recycling box 24 recycles the welding slag dropped by the PCB board, which is convenient for its collection.

[0026] During specific work, the PCB board is placed on the workbench 2 for welding processing. The limit clamp 13 limits the workbench 2, drives the outer end of the limit frame to move, and rotates the workbench 2 180 degrees so that the PCB board faces downward. The adjustment motor 16 is started to drive the adjustment cam 17 to rotate, and the upper frame 14 is driven to move up and down through the spring rod 12, so that the welding slag on the surface of the PCB board can be cleaned, and the welding effect of the PCB board and the electronic components can be detected, and the unwelded components will be detached to avoid welding errors.
