Abstract
Description
Technical Field
[0001] This utility model relates to the field of wave soldering technology, specifically a wave soldering fixture that is not easily stuck to solder. Background Technology
[0002] Wave soldering is a process where the soldering surfaces of a circuit board come into direct contact with high-temperature liquid solder to achieve the soldering purpose. The high-temperature liquid solder is maintained at an angle, and a special device makes the liquid solder form waves, hence the name "wave soldering." With the increasing awareness of environmental protection, lead-free processes are gradually emerging, using tin-silver-copper alloys and special fluxes, and requiring higher preheating temperatures for soldering.
[0003] Most of the fixtures currently in use are difficult to prevent from sticking to the solder, resulting in poor soldering performance. They are also difficult to install and fix, leading to poor installation stability and practicality. Utility Model Content
[0004] The purpose of this invention is to provide a wave soldering fixture that is not easily stuck to solder, so as to solve the problems mentioned in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wave soldering fixture that is not easily stuck to solder, comprising a fixture body and a carrier plate, the fixture body comprising a cooling mechanism comprising a square pipe, the bottom of the carrier plate being provided with a square pipe, one end of the square pipe being provided with a water tank, the top of the water tank being provided with a cover plate, the top of the cover plate being provided with a handle, the outer wall of the square pipe being provided with a water pump, and the other end of the square pipe being fixedly connected to one side of the water tank.
[0006] As a preferred technical solution, the top of the water tank is provided with an opening, the shape and size of which match the shape and size of the cover plate, and the water tank is hinged to the cover plate through the opening.
[0007] As a preferred technical solution, a carrier plate is provided at the bottom of the fixture body, a through hole is provided inside the fixture body, and a through hole is provided at the top of the carrier plate.
[0008] As a preferred technical solution, a mounting and fixing mechanism is provided on one side of the fixture body, the mounting and fixing mechanism including a mounting plate, and the mounting plate is provided on one side of the fixture body.
[0009] As a preferred technical solution, the number of mounting plates is six, and the mounting plates have a first mounting hole inside.
[0010] As a preferred technical solution, a mounting block is provided on one side of the fixture body, and the number of mounting blocks is four.
[0011] As a preferred technical solution, the mounting block has a second mounting hole inside, and the number of the second mounting holes is four sets, with two holes in each set.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of a cooling mechanism, can achieve the function of cooling the fixture body to prevent solder from sticking. During use, the coolant in the water tank is input into the square pipe by starting the water pump, so that the pipe cools the carrier plate, and the carrier plate cools the fixture body, making it less likely to be stuck to the solder. In addition, the fixture body contains titanium alloy, which can be reused and is not easily stuck to the solder. This avoids the situation where the solder sticks to the fixture, which is difficult to prevent, may change the shape and height of the wave soldering peak, resulting in poor contact between the component leads and the solder during soldering, and defects such as cold solder joints and missing solder joints. Furthermore, the stuck solder may also form solder dross on the fixture, affecting the fluidity and wettability of the solder. This ensures the welding effect and welding quality of the fixture.
[0014] 2. This utility model, through the setting of the installation and fixing mechanism, can facilitate the installation, fixing and assembly of the fixture body. During use, the carrier plate and the fixture body are installed and fixed together by inserting bolts into the first mounting hole of the mounting plate, and the fixture is fixed in a specific position by inserting bolts into the second mounting hole of the mounting block. This can avoid the situation where the fixture is not securely installed due to difficulty in installing and fixing it, and is prone to shaking or displacement during wave soldering, causing deviation in the soldering position of the circuit board. This ensures the installation firmness and practicality of the fixture. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a fixture body 1 and a carrier plate 4. The fixture body 1 includes a cooling mechanism 2. The carrier plate 4 is provided at the bottom of the fixture body 1. A through hole 5 is provided inside the fixture body 1. A through hole 5 is provided at the top of the carrier plate 4. An installation and fixing mechanism 3 is provided on one side of the fixture body 1.
[0023] Specifically: When the fixture body 1 is needed, the carrier plate 4 needs to be installed and fixed together with the fixture body 1, and then the fixture body 1 is fixed in a specific position for use. The installation and fixing mechanism 3 is used to install and fix the carrier plate 4 and the fixture body 1 together, and then the fixture body 1 is fixed in a specific position for use. After installation and fixing, the fixture body 1 can be used for work. The wave soldering position is positioned through the through hole 5 on the fixture body 1. During the wave soldering process, it is necessary to prevent the solder from sticking. At this time, it is necessary to cool the surface of the fixture body 1. The cooling mechanism 2 is used to cool the surface of the fixture body 1 to prevent the solder from sticking, thereby completing the work.
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixture body 1 includes a cooling mechanism 2, which includes a square pipe 201. The bottom of the carrier plate 4 is provided with a square pipe 201. One end of the square pipe 201 is provided with a water tank 202. The top of the water tank 202 is provided with a cover plate 203. The top of the cover plate 203 is provided with a handle 204. The outer wall of the square pipe 201 is provided with a water pump 205. The other end of the square pipe 201 is fixedly connected to one side of the water tank 202. The top of the water tank 202 is provided with a through-hole. The shape and size of the through-hole match the shape and size of the cover plate 203. The water tank 202 is hinged to the cover plate 203 through the through-hole.
[0025] During wave soldering, it is necessary to prevent solder from sticking. This requires cooling the surface of the fixture body 1. The cover 203 is opened via handle 204, and an appropriate amount of coolant is poured into the water tank 202. The water pump 205 is then started, drawing coolant from the tank 202 and channeling it into the square pipe 201. The square pipe 201 is in contact with the bottom of the carrier plate 4, allowing the coolant in the pipe to cool the carrier plate 4, which in turn cools the surface of the fixture body 1, preventing solder from sticking to the fixture body 1. Once cooled, the coolant in the square pipe 201 is pumped back into the water tank 202 via the water pump 205. Since the fixture body 1 itself contains titanium alloy, which is reusable and not easily stuck to solder, the cooling and anti-sticking process is completed.
[0026] like Figure 1 , Figure 2 and Figure 5 As shown, a mounting and fixing mechanism 3 is provided on one side of the fixture body 1. The mounting and fixing mechanism 3 includes a mounting plate 301. There are six mounting plates 301 on one side of the fixture body 1. The mounting plates 301 have first mounting holes 302 inside. There are four mounting blocks 303 on one side of the fixture body 1. The mounting blocks 303 have second mounting holes 304 inside. There are four sets of second mounting holes 304, with two holes in each set.
[0027] Specifically: When the fixture body 1 is needed, the carrier plate 4 and the fixture body 1 need to be installed and fixed together, and then the fixture body 1 is fixed in a specific position for use. At this time, the fixture body 1 and the carrier plate 4 are attached together, and the first mounting hole 302 in the mounting plate 301 on the fixture body 1 is aligned with the first mounting hole 302 in the carrier plate 4. Then, the bolt is inserted into the first mounting hole 302 to fix the mounting plate 301, so that the fixture body 1 and the carrier plate 4 are fixed. Then, the mounting block 303 on the fixture body 1 is attached to the specific position, and the second mounting hole 304 in the mounting block 303 is aligned with the second mounting hole 304 in the specific position. Then, the bolt is inserted into the second mounting hole 304 to install and fix the fixture body 1 in the specific position, thereby completing the installation and fixing work.
[0028] The working principle of this utility model is as follows: When the fixture body 1 is needed, the carrier plate 4 and the fixture body 1 need to be installed and fixed together, and then the fixture body 1 is fixed in a specific position for use. At this time, the fixture body 1 and the carrier plate 4 are attached together, and the first mounting hole 302 in the mounting plate 301 on the fixture body 1 is aligned with the first mounting hole 302 in the carrier plate 4. Then, the bolt is inserted into the first mounting hole 302 to fix the mounting plate 301, thus fixing the fixture body 1 and the carrier plate 4. Then, the mounting block 303 on the fixture body 1 is attached to the specific position, and the second mounting hole 304 in the mounting block 303 is aligned with the second mounting hole 304 in the specific position. Then, the bolt is inserted into the second mounting hole 304 to install and fix the fixture body 1 in the specific position, thereby completing the installation and fixing work. After installation and fixing, the fixture body 1 can be used. The fixture body 1 operates by positioning the wave soldering position through the through-hole 5 on the fixture body 1. During the wave soldering process, it is necessary to prevent solder from sticking together. At this time, it is necessary to cool the surface of the fixture body 1. The cover plate 203 is opened by the handle 204, and an appropriate amount of coolant is poured into the water tank 202. Then, the water pump 205 is started to draw the coolant from the water tank 202 and input it into the square pipe 201. The square pipe 201 is attached to the bottom of the carrier plate 4, so that the coolant in the square pipe 201 cools the carrier plate 4, and the carrier plate 4 cools the surface of the fixture body 1 to prevent the solder from sticking to the fixture body 1. After cooling, the coolant in the square pipe 201 is input back into the water tank 202 by the water pump 205. The fixture body 1 itself contains titanium alloy, which can be reused and is not easily stuck by solder, thus completing the cooling and anti-sticking work.
[0029] 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.
