Technical Field

[0001] This utility model relates to the field of wave soldering technology, specifically to a wave soldering furnace fixture. Background Technology

[0002] Wave soldering is a process in which the soldering surface of a circuit board comes into direct contact with high-temperature liquid solder to achieve the soldering purpose. The high-temperature liquid solder is kept on an inclined plane, and a special device makes the liquid solder form waves, hence the name wave soldering. During the wave soldering process, a reflow fixture is needed to fix the circuit board.

[0003] Traditional wave soldering fixtures have a rectangular frame, and the rectangular frame is the same as the fixture base. During wave soldering, solder liquid is prone to overflow, and the bottom fixture base is prone to damage due to high temperature, affecting its service life. At the same time, the grippers used to hold the fixture are prone to contact with solder liquid. Utility Model Content

[0004] The purpose of this utility model is to provide a wave soldering reflow fixture to solve the problems mentioned in the background art, such as solder liquid easily overflowing during use, affecting service life, and the clamps easily coming into contact with solder liquid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wave soldering furnace fixture, including a fixture base, with positioning grooves on both sides of the surface of the fixture base, a frame mechanism on the surface of the fixture base, the frame mechanism including upper and lower frames and a frame assembly inside, a clamping mechanism on the surface of the fixture base, the clamping mechanism being located inside the frame mechanism, the clamping mechanism including a limiting pressure strip, a limiting pressure block, a locking bolt and a fastening stud inside, a conventional fixture on one side of the fixture base, upper and lower edge strips fixed to both sides of the surface of the conventional fixture by screws, side strips on both sides of the upper and lower edge strips, the side strips being detachably connected to the conventional fixture by screws, and one side of the side strip and one side of the conventional fixture being located in the same vertical plane.

[0006] Preferably, upper and lower frame borders are provided at the edges of both sides of the fixture base. The upper and lower frame borders are detachably connected to the fixture base by screws. A frame assembly is provided between the upper and lower frame borders, and the frame assembly is located at the edges of both sides of the fixture base.

[0007] Preferably, the frame assembly consists of a side frame and an extension strip. The side frame is detachably connected to the edges of both sides of the fixture seat by screws. One side of the side frame and one side of the fixture seat are located in the same vertical plane.

[0008] Preferably, one end of the side frame is fixed with an extension strip, which is located on the outside of the fixture base.

[0009] Preferably, limiting strips are provided on both sides of the surface of the fixture seat, and the limiting strips are located outside the positioning groove.

[0010] Preferably, one end of the limiting pressure strip is provided with a locking bolt, and one end of the locking bolt passes through the limiting pressure strip and is threaded into the surface of the fixture seat.

[0011] Preferably, a limiting block is provided between each of the positioning grooves, and a fastening stud is provided at the center of the limiting block. One end of the fastening stud passes through the limiting block and engages with the surface thread of the fixture seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the wave soldering reflow fixture is equipped with a frame mechanism. Since the extended edge strip is located on the outside of the fixture seat, the jaws of the fixture can be used to clamp the surface of the extended edge strip during wave soldering. Since the frame assembly is located above the fixture seat, one side of the jaws can be lower than the fixture seat, which prevents the jaws from contacting the solder liquid during soldering. At the same time, it can prevent the solder liquid from overflowing and also prevent the fixture seat from being damaged due to high temperature, thus extending the service life of the fixture.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The structure of the wave soldering furnace fixture provided by this utility model is as follows: Figure 1 and Figure 2 As shown, it includes a fixture base 1, and positioning grooves 11 are provided on both sides of the surface of the fixture base 1.

[0020] Furthermore, such as Figure 2 and Figure 3 As shown, the surface of the jig base 1 is provided with a frame mechanism 2. The interior of the frame mechanism 2 includes upper and lower frame edges 21 and a frame assembly 22. The upper and lower frame edges 21 are covered at the edges of both sides of the jig base 1. The upper and lower frame edges 21 are detachably connected to the jig base 1 by screws. The frame assembly 22 is provided between the upper and lower frame edges 21. The frame assembly 22 is located at the edges of both sides of the jig base 1. The frame assembly 22 is composed of a side frame edge 221 and an extension strip 222. The side frame edge 221 is detachably connected to the edges of both sides of the jig base 1 by screws. One side of the side frame edge 221 and one side of the jig base 1 are located in the same vertical plane. An extension strip 222 is fixed to one end of the side frame edge 221. The extension strip 222 is located on the outside of the jig base 1.

[0021] When in use, since the extension strip 222 is located on the outside of the fixture seat 1, the jaws of the fixture can be used to hold the surface of the extension strip 222 during wave soldering. Since the frame assembly 22 is located above the fixture seat 1, one side of the jaws can be lower than the fixture seat 1, which prevents the jaws from contacting the solder liquid during soldering. At the same time, it can prevent the solder liquid from overflowing and also prevent the fixture seat 1 from being damaged due to high temperature.

[0022] Furthermore, such as Figure 2As shown, a clamping mechanism 3 is provided on the surface of the fixture base 1. The clamping mechanism 3 is located inside the frame mechanism 2. The clamping mechanism 3 includes a limiting pressure strip 31, a limiting pressure block 32, a locking bolt 33, and a fastening stud 34. Limiting pressure strips 31 are provided on both sides of the surface of the fixture base 1. The limiting pressure strips 31 are located outside the positioning grooves 11. A locking bolt 33 is provided at one end of the limiting pressure strip 31. One end of the locking bolt 33 passes through the limiting pressure strip 31 and is threadedly engaged with the surface of the fixture base 1. Limiting pressure blocks 32 are provided between the positioning grooves 11. A fastening stud 34 is provided at the center of the limiting pressure block 32. One end of the fastening stud 34 passes through the limiting pressure block 32 and is threadedly engaged with the surface of the fixture base 1.

[0023] In use, place the circuit board to be wave soldered into the positioning groove 11, then loosen the locking bolt 33, and then rotate the limiting pressure strip 31 so that one end of the limiting pressure strip 31 rotates to the surface of the circuit board to press the circuit board. Then tighten the locking bolt 33 to fix the limiting pressure strip 31. Similarly, by loosening the fastening stud 34 and rotating the limiting pressure block 32, the two ends of the limiting pressure block 32 press the circuit boards on both sides respectively. Then tighten the fastening stud 34 to fix the limiting pressure block 32, so as to realize the clamping and fixing function of the fixture on the circuit board.

[0024] Furthermore, such as Figure 4 As shown, a conventional fixture 4 is provided on one side of the fixture base 1. Both sides of the surface of the conventional fixture 4 are fixed with upper and lower edge strips 41 by screws. Both sides of the upper and lower edge strips 41 are provided with side strips 42. The side strips 42 are detachably connected to the conventional fixture 4 by screws. One side of the side strip 42 and one side of the conventional fixture 4 are located in the same vertical plane.

[0025] Working principle: In use, first place the circuit board to be wave soldered into the positioning groove 11, then loosen the locking bolt 33, and then rotate the limiting pressure strip 31 so that one end of the limiting pressure strip 31 rotates to the surface of the circuit board to press the circuit board. Then tighten the locking bolt 33 to fix the limiting pressure strip 31. Similarly, by loosening the fastening stud 34 and rotating the limiting pressure block 32, the two ends of the limiting pressure block 32 press the circuit boards on both sides respectively. Then tighten the fastening stud 34 to fix the limiting pressure block 32, so as to realize the function of clamping and fixing the circuit board by the fixture.

[0026] In use, since the extension strip 222 is located on the outside of the fixture seat 1, during wave soldering, the jaws of the fixture can be used to hold the surface of the extension strip 222. Since the frame assembly 22 is located above the fixture seat 1, one side of the jaws can be lower than the fixture seat 1, which prevents the jaws from contacting the solder liquid during soldering. At the same time, it can prevent the solder liquid from overflowing and also prevent the fixture seat 1 from being damaged due to high temperature, thus extending the service life of the fixture and finally completing the use of the fixture.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
