Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of magnetic core fixture, especially relates to a wave soldering fixture for multiple magnetic cores of different heights. BACKGROUND

[0002] In the manufacturing process of electronic products, the welding quality of magnetic cores as key components directly affects the performance and reliability of products. Traditional magnetic core welding methods mostly use manual welding, which is not only inefficient, but also difficult to guarantee welding quality. With the development of automation technology, wave soldering technology is widely used in the welding process of magnetic cores. However, the magnetic core is prone to displacement due to uneven heating or external force during wave soldering, resulting in poor welding. Therefore, it is particularly important to design a fixture device that can effectively fix the position of the magnetic core and prevent it from displacing during wave soldering.

[0003] Existing wave soldering fixtures for magnetic cores mostly use simple clamps or pressing plates to fix the magnetic core, but these devices often have problems such as unstable fixation, inaccurate positioning, etc., making it difficult to meet the production needs of high precision and high efficiency. In addition, some fixture devices are relatively complex in structure, not only increasing the manufacturing cost, but also possibly causing inconvenience in operation and affecting production efficiency.

[0004] Therefore, it is necessary to invent a wave soldering fixture for multiple magnetic cores of different heights. SUMMARY

[0005] To solve the above technical problems, the utility model provides a wave soldering fixture for multiple magnetic cores of different heights, which includes a magnetic core fixture plate, magnetic core products, magnetic core pressing plates, spring positioning needles, counterweights and positioning columns. The magnetic core fixture plate is placed with several magnetic core products, and multiple magnetic core pressing plates are positioned and pressed on the magnetic core fixture plate through spring positioning needles. Two counterweights are fixed and installed on each magnetic core pressing plate in mirror symmetry, and four positioning columns are installed on each magnetic core pressing plate and inserted into the positioning holes of the magnetic core fixture plate.

[0006] Preferably, the spring positioning needles are arranged in a rectangular array, and each group of spring positioning needles corresponds to a single magnetic core product.

[0007] Preferably, the spring positioning needle is composed of a needle cylinder, a spring, a needle rod and a needle head. The needle rod is elastically and slidably installed with the needle cylinder through the spring, and the needle rod is fixedly installed with a needle head required for positioning the magnetic core product at one end. The needle cylinder is fixedly installed on the magnetic core pressing plate.

[0008] Preferably, a plurality of groups of the spring positioning needles are distributed around the counterweight block, the counterweight block is an "L"-shaped structure, and two adjacent counterweight blocks are in an inverted "儿"-shaped structure.

[0009] Preferably, two mirror-symmetrical clamps are rotatably mounted on the magnetic core pressing plate, and the clamping protrusions provided at the lower ends of the clamps are clamped together with the magnetic core fixture plate.

[0010] Preferably, a pressing head is integrally provided on the upper end of the clamping head, and the pressing head is an "S"-shaped end head.

[0011] Preferably, the pressing head contacts the upper end of a spring sheet fixedly mounted on the magnetic core pressure plate below, and the spring sheet is installed obliquely on the magnetic core pressure plate as a whole, and the downward pressure of the pressing head allows the spring sheet to be deformed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model realizes the rapid positioning and stable fixation of the magnetic core through the ingenious combination of components such as the magnetic core fixture plate, the magnetic core pressure plate, and the spring positioning pin.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 drawings:

[0022] The wave peak welding jig provided by the present application can be used for multiple unequal height magnetic cores, which comprises a magnetic core jig plate 1, a magnetic core product 2, a magnetic core pressing plate 3, a spring positioning needle 4, a counterweight 5 and a positioning column 6, a plurality of magnetic core products 2 are arranged on the magnetic core jig plate 1, a plurality of magnetic core pressing plates 3 are positioned and pressed on the magnetic core jig plate 1 through the spring positioning needles 4, two counterweights 5 are fixedly installed on each magnetic core pressing plate 3 in mirror symmetry, and four positioning columns 6 are installed on each magnetic core pressing plate 3 and inserted into the positioning holes penetratingly arranged on the magnetic core jig plate 1.

[0023] Further, a plurality of spring positioning needles 4 are organized into a group, and these spring positioning needles 4 are distributed in a rectangular array. Each group of spring positioning needles 4 corresponds to a single magnetic core product 2, and such design makes the fixation more accurate and stable.

[0024] Further, specific to the composition of the spring positioning needle 4, it includes a needle cylinder, a spring, a needle rod, and a needle head. The needle rod is elastically slidingly installed with the needle cylinder through the spring, which means that the needle rod can have a certain expansion space when subjected to external force. One end of the needle rod is fixedly installed with the needle head, which is used to position the magnetic core product 2. The needle cylinder is fixedly installed on the magnetic core pressing plate 3, ensuring the stability of the entire structure.

[0025] Further, a plurality of spring positioning needles 4 are cleverly distributed around the counterweight 5. The counterweight 5 adopts an "L" type structure, which allows two adjacent counterweights 5 to form an inverted "er" character structure. Such a layout not only helps to stabilize the entire device, but also ensures the positional accuracy of the magnetic core during the welding process.

[0026] Further, two mirror-symmetrical clamping heads 7 are rotatably installed on the magnetic core pressing plate 3. The lower ends of the two clamping heads 7 are provided with clamping protrusions, which can be clamped with the magnetic core jig plate 1 to achieve stable connection. Such a design allows the magnetic core pressing plate 3 to be conveniently installed on the magnetic core jig plate 1 and ensures that it will not shake during the welding process.

[0027] Further, the upper end of the clamping head 7 is integrally provided with a pressing head 8, which adopts an "S" type end design. Such a design allows the pressing head 8 to rotate more flexibly when subjected to force, while increasing the comfort of use. The pressing head 8 is in contact with the upper end of the spring sheet 9 fixedly installed on the magnetic core pressing plate 3 below. The spring sheet 9 is integrally and obliquely installed on the magnetic core pressing plate 3, which means that when the pressing head 8 is pressed down, it can drive the spring sheet 9 to deform, thereby further ensuring the stable connection between the magnetic core pressing plate 3 and the magnetic core jig plate 1.

[0028] The working principle is as follows: First, the magnetic core product 2 is accurately placed on the predetermined position of the magnetic core jig plate 1. The design of the magnetic core jig plate 1 ensures that the magnetic core product 2 can be arranged according to the established layout, laying the foundation for the subsequent positioning and pressing steps.

[0029] Then, the magnetic core pressing plate 3 is aligned with the magnetic core product 2 through the spring positioning needle 4. Each group of spring positioning needles 4 corresponds to a single magnetic core product 2 and is distributed in a rectangular array, which ensures the accuracy and stability of positioning. The needle head part of the spring positioning needle 4 will accurately insert into the corresponding position of the magnetic core product 2, and through the elastic action of the spring, the preliminary fixation of the magnetic core product 2 is realized.

[0030] During this process, the positioning column 6 on the magnetic core pressing plate 3 is inserted into the positioning hole through the magnetic core jig plate 1. This further enhances the connection stability between the magnetic core pressing plate 3 and the magnetic core jig plate 1, ensuring that the magnetic core product 2 will not shift during the welding process.

[0031] The counterweight 5 installed on the magnetic core pressing plate 3 not only helps to stabilize the entire device, but also provides additional weight support during the welding process, ensuring the positional accuracy of the magnetic core product 2.

[0032] On the magnetic core pressing plate 3, two mirror-symmetric clamping heads 7 are also installed. The clamping convexes at the lower end of the clamping heads 7 are clamped with the corresponding positions on the magnetic core jig plate 1, realizing the stable connection between the magnetic core pressing plate 3 and the magnetic core jig plate 1. Such a design allows the magnetic core pressing plate 3 to remain fixed during the welding process and not to shake. In addition, the upper end of the clamping head 7 is also integrally provided with a pressing head 8. When it is necessary to disassemble or adjust the magnetic core pressing plate 3, the pressing head 8 can be pressed to make the spring sheet 9 deform, thereby releasing the clamping force between the clamping head 7 and the magnetic core jig plate 1. Such a design not only facilitates operation, but also increases the comfort of use.

[0033] Finally, when all the components are installed in place, the entire wave soldering jig for multiple magnetic cores of different heights is ready. During the wave soldering process, the magnetic core product 2 is stably fixed on the magnetic core jig plate 1, and through the heating and welding action of the wave soldering machine, mechanical and electrical connection between the component soldering end or pin and the printed board pad is realized.

[0034] Any similar technical solution designed by using the technical solution of the present application or inspired by the technical solution of the present application and achieving the above technical effects falls within the protection scope of the present application.
