[0001] The utility model relates to the technical field of wave soldering jigs, in particular to a wave soldering jig which is convenient for replacing a carrier board. Background Art

[0002] Wave soldering fixture is a PCB fixture used for SMT processing. It is suitable for various PCB boards with SMD components on the solder side of the plug-in material. It is a new type of fixture designed to ensure that during the wave soldering process, the soldering surface of the PCB board can directly contact with the high-temperature liquid tin, so as to achieve the purpose of soldering.

[0003] During the use of existing wave soldering jigs, the carrier board installed on the wave soldering jig may age or be damaged due to factors such as frequent use, high temperature environment or mechanical stress. The aged carrier board may affect the fixing effect of components and cause the welding efficiency of the wave soldering jig to be reduced.

[0004] In order to overcome the above-mentioned defects, the prior art (application number: 201621439965.1, Chinese patent with application date of 2016.12.24) discloses an automatically detachable wave soldering fixture, which is fixedly installed by a snap-fit method and can be cooperated with automated equipment, such as a robot kit, to achieve the effect of automatic disassembly, thereby greatly improving work efficiency.

[0005] Although the existing technology can solve the problem of automatic disassembly of the wave soldering jig, since the wave soldering jig is installed and disassembled by means of buckles, the carrier board can be replaced. However, after the carrier board is replaced many times, the wear or loosening of the buckles may affect the repeated positioning accuracy of the carrier board, thereby affecting the welding quality, resulting in poor replacement of the carrier board, and the replaced carrier board cannot be fixed, and the workpiece cannot be fixed, thereby reducing the working efficiency of the wave soldering jig.

[0031] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0032] Embodiment 1: To solve the problem that when a wave soldering fixture for facilitating the replacement of a carrier plate on the market is in use, since the wave soldering fixture is installed and disassembled by means of a buckle, the carrier plate can be replaced.

A through hole 19 is formed inside the limiting plate 20, a pulling plate 21 is fixedly connected to the top of the limiting plate 20, a rotating rod 18 is fixedly installed on the top of the telescopic rod 17, and the top of the rotating rod 18 penetrates through the through hole 19. The rotating rod 18 is rotatably connected to the through hole 19, and the through hole 19 and the limiting plate 20 are integrally arranged.

[0033] When the carrier plate body 2 needs to be replaced through the wave soldering fixture, after the pressing plate 12 is outside the wave soldering fixture body 1, the staff manually rotates the limiting plate 20 outwards, so that the limiting plate 20 drives the rotating rod 18 to rotate in the corresponding through hole 19, so that each limiting plate 20 rotates outwards and disengages from the carrier plate body 2, and the carrier plate body 2 can be disassembled and replaced. After the carrier plate body 2 is replaced inside the wave soldering fixture body 1, the limiting plate 20 is rotated inwards, so that the limiting plate 20 is located above the carrier plate body 2. The resilience of the strong spring 15 drives the telescopic rod 17 connected to the sliding plate 16 to move downwards, so that the telescopic rod 17 drives the limiting plate 20 to move downwards, so that the limiting plate 20 fits on the carrier plate body 2 for fixation, and the replaced carrier plate can be installed and fixed.

[0034] Embodiment 2: The workpiece 3 can be fixed to improve the working efficiency of the wave soldering fixture, which can be referred to in the attached Figure 1 - attached Figure 5, three grooves 5 are formed inside the fixing cylinder 4.

The pressing plate 12 is fixedly connected to the connecting rods 11. The connecting rods 11 are rotatably connected to the activity sleeve 10.

[0035] The processed part 3 by soldering is placed on the carrier body 2, causing the pressing plate 12 to rotate inwards. Thus, the pressing plate 12 drives the connecting rod 11 to rotate within the activity sleeve 10. After the pressing plate 12 drives the protective pad 13 to be located on the processed part 3, the resilience of the compression spring 7 drives the connecting plate 9 connected to the moving ring plate 8 to move downwards through the corresponding groove 5, causing the three connecting plates 9 to simultaneously drive the connecting rod 11 and the pressing plate 12 connected to the activity sleeve 10 to move downwards. Thus, the protective pad 13 connected to the pressing plate 12 fits on the processed part 3, and the processed part 3 can be fixed, improving the working efficiency of the wave soldering fixture.
