Description

Technical Field

[0001] This utility model relates to the field of wave soldering fixture technology, and more specifically, to a wave soldering fixture that can be automatically disassembled. Background Technology

[0002] With the development of science and technology and the improvement of people's living standards, modern people use many electrical appliances in their lives. These appliances all use circuit boards, and wave soldering is required for the circuit boards during the component soldering process.

[0003] According to Chinese Patent CN202121039562.9, an automatically detachable wave soldering fixture is disclosed. This application involves two cover plates symmetrically slidingly connected to the upper end of a housing. Two limiting grooves are symmetrically formed on the inner wall of a sliding groove at the upper end of the housing. A first slider at the lower end of the cover plate is slidably connected to the sliding groove, and a limiting block at the lower end of the first slider is slidably connected to the limiting groove. Multiple serrations are provided at one end of a clamping plate, and a rack that meshes with the serrations is fixedly connected to the lower end of the cover plate. A spring is fixedly connected in a mounting groove at the upper end of the housing, and a plug rod is fixedly connected to the upper end of the spring. A corresponding insertion hole for the plug rod is formed on the cover plate. The PCB board can be fixed by sliding the cover plate, facilitating the installation and removal of the PCB board from the wave soldering fixture, reducing time costs, and improving work efficiency. Existing automatically detachable wave soldering fixtures limit the PCB board by moving the sliding cover plate to rotate the clamping plate. However, the clamping plate cannot limit PCB boards of different thicknesses, limiting its applicability.

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, an automatically detachable wave soldering fixture is provided. Example

[0018] like Figure 1-4 As shown, the automatically detachable wave soldering fixture according to an embodiment of the present utility model includes a housing 1, a cover plate 2 at the top of the housing 1, the cover plate 2 being connected to the housing 1 via a connector, a groove 3 being provided at the bottom of the housing 1, a bottom plate 4 being provided in the groove 3, a mounting plate 5 being provided at the bottom of the cover plate 2, and an elastic clamping member being provided at the bottom of the mounting plate 5. Example

[0019] like Figure 1-4 As shown, the device includes a housing 1, a cover plate 2 at the top of the housing 1, and a connecting piece connecting the cover plate 2 to the housing 1. A groove 3 is formed at the bottom of the housing 1, and a base plate 4 is located within the groove 3. A mounting plate 5 is located at the bottom of the cover plate 2, and an elastic clamping element is located at the bottom of the mounting plate 5. Symmetrically arranged connecting grooves 6 are formed at the top of the housing 1. A connecting plate 7 matching the connecting grooves 6 is located at the bottom of the cover plate 2. Symmetrically arranged hand-tightening bolts 8 are formed on both sides of the housing 1, with one side of each hand-tightening bolt extending into the connecting groove 6. A threaded groove 9 matching the hand-tightening bolt 8 is formed on one side of the connecting plate 7. Threaded holes matching the hand-tightening bolts 8 are formed on the housing 1. The elastic clamping element includes several evenly distributed compression sleeves 10 at the bottom of the mounting plate 5. A matching connecting slider 11 is located within each compression sleeve 10. A compression spring 12 is located at the top of each connecting slider 11, and a pressure rod 13 is located at the bottom of the connecting slider 11. The bottom of the pressure rod 13 extends outside the compression sleeve 10 and connects to a pressure plate 14. The connecting slider 11 is connected to the compression sleeve 10 via a compression spring 12. The bottom end of the compression sleeve 10 has a sliding hole that matches the pressure rod 13. The bottom end of the connecting plate 7 is provided with a protective pad 15.

[0020] In practical applications, when fixing the PCB board, first place the PCB board into the groove 3 in the housing 1, then cover it with the cover plate 2, insert the connecting plate 7 on the cover plate 2 into the connecting groove 6 on the housing 1, press the cover plate 2 into tight contact with the housing 1, and then turn the hand-tightening bolt 8 to fix the connecting plate 7. During this process, when the cover plate 2 is pressed, the pressure rod 13 on the cover plate 2 will squeeze the PCB board through the pressure plate 14. The pressure rod 13 will be compressed through the connecting slider 11 to compress the compression spring 12, so the pressure rod 13 will move into the compression sleeve 10, so that the pressure rod 13 can press and limit the PCB board of different thicknesses. By setting the elastic clamping component, the PCB board of different thicknesses can be pressed and fixed, improving its applicability. When disassembling, the PCB board can be taken out by removing the cover plate, which saves time and effort.

[0021] In summary, by utilizing the above-mentioned technical solution of this utility model, PCB boards of different thicknesses can be pressed and fixed by setting up elastic clamping components, thereby improving its applicability. When disassembling, the PCB board can be removed by simply removing the cover plate, saving time and effort.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
