Description

Technical Field

[0001] This utility model relates to the field of reflow tooling technology, and in particular to a reflow tooling for a sound-generating unit. Background Technology

[0002] Currently, the reflow of sound-generating monomers requires six processes: SMT placement of finished products, UV curing, transfer to high-temperature film, high-temperature film reflow, transfer to blue film, and testing and packaging. The existing reflow method has the following problems: (1) many processes and low efficiency; (2) three types of film materials are used in the reflow process, namely UV film, high-temperature film and blue film. The dimensions of these three types of films are required to be 23 cm long and 22.5 cm wide. Each reel can only hold 728 sound-generating monomers, resulting in high film material costs; (3) the reflow tooling is prone to deformation after passing through the high-temperature zone and cooling zone of the reflow oven, which is not conducive to the continued use of subsequent SMT equipment, resulting in tooling waste and increased production costs. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a sound-generating unit reflow fixture to solve the problems of multiple processes, low efficiency, easy deformation of the fixture, and high cost in traditional sound-generating unit reflow.

[0004] This utility model provides a sound-generating unit recirculation fixture, comprising: a base fixture, a product placement fixture disposed on the base fixture, an upper cover disposed on the product placement fixture, and an upper cover positioning block, wherein...

[0005] The product placement fixture is used to carry the sound-generating unit. The upper cover is positioned on the product placement fixture carrying the sound-generating unit to be returned by the upper cover positioning block. The base fixture is positioned with the product placement fixture after return.

[0006] Preferably, product positioning slots are evenly provided on the product placement fixture, and the sound-generating unit is placed in the product positioning slots.

[0007] Preferably, the upper cover is provided with air holes, which are used to allow hot air from the reflow oven to flow into the product placement fixture.

[0008] Preferably, the pores are evenly arranged, and the size of the pores is smaller than the size of the sound-generating unit.

[0009] Preferably, both the product placement fixture and the base fixture are provided with positioning holes, and the product placement fixture is positioned on the base fixture through the positioning holes and positioning pins that match the positioning holes.

[0010] Preferably, a steel ring is provided between the product placement fixture and the base fixture, and the steel ring is used to position the sound-generating unit in the product positioning groove.

[0011] Preferably, the steel ring is positioned on the base fixture by the positioning pin and the product placement fixture.

[0012] Preferably, base support blocks for supporting the base fixture are provided at the four corners of the base fixture.

[0013] As can be seen from the above technical solution, the sound-generating unit reflow fixture provided by this utility model adopts an integrated structure, which can directly support the sound-generating unit.

[0021] In response to the aforementioned problems of excessive steps, low efficiency, easy deformation of tooling, and high cost in the existing sound-generating unit reflow process, this utility model proposes a sound-generating unit reflow tooling.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] To illustrate the structure of the sound-generating unit recirculation fixture provided by this utility model Figure 1 The structure of the sound-generating unit recirculation fixture according to an embodiment of the present invention is shown.

[0024] like Figure 1 As shown, the sound-generating unit recirculation fixture provided by this utility model includes: a base fixture 3, a product placement fixture 2 disposed on the base fixture 3, an upper cover 1 disposed on the product placement fixture 2, and an upper cover positioning block 5. The product placement fixture 2 is used to carry the sound-generating unit, and the upper cover 1 is positioned on the product placement fixture 2 carrying the sound-generating unit to be recirculated by the upper cover positioning block 5. The base fixture 3 and the recirculated product placement fixture 2 are mutually positioned.

[0025] The product placement fixture 2 is provided with product positioning slots 21 evenly distributed, and the sound-generating unit is placed in the product positioning slots 21. The product positioning slots 21 are matched with the shape of the sound-generating unit and are used to position the sound-generating unit on the product placement fixture 2. The product positioning slots 21 enable the sound-generating unit to be accurately mounted. That is to say, the SMT equipment directly picks up the sound-generating unit and accurately mounts it into the product positioning slots 21 of the product placement fixture 2.

[0026] The upper cover 1 is provided with air holes 11, which are used to allow hot air from the reflow oven to flow into the product placement fixture 2. The air holes 11 are evenly arranged, and the size of the air holes 11 is smaller than the size of the sound-generating unit to prevent the sound-generating unit from falling out of the air holes 11.

[0027] In this embodiment of the invention, the function of the upper cover 1 is to help press the sound-generating unit placed in the product positioning groove 21 firmly. That is, the upper cover 1 presses the sound-generating unit firmly into the product positioning groove in the product placement fixture 2, making the positioning of the sound-generating unit more accurate. The air hole 11 is for high-temperature gas to enter the product placement fixture 2 during recirculation, so that the sound-generating unit is in a better recirculation temperature.

[0028] The upper cover 1 is positioned on the product placement fixture 2 by the upper cover positioning block 5. The positioning method of the upper cover 1 and the product placement fixture 2 can be achieved by the upper cover positioning block 5 using pins, positioning pins or bolts. There is no specific limitation here. The appropriate method can be selected to position the upper cover 1 and the product placement fixture 2 according to the actual situation.

[0029] During the reflow process, only the top cover 1 and the product placement fixture 2 are reflowed. After the reflow is completed, the product placement fixture 2 and the base fixture 3 are positioned together for film application. The product placement fixture 2 is positioned on the base fixture 3 by the positioning pin 6.

[0030] Specifically, as an example, positioning holes are provided on both the product placement fixture 2 and the base fixture 3. The product placement fixture 2 is positioned on the base fixture 3 through the positioning holes and the positioning pins 6 that match the positioning holes.

[0031] A steel ring can also be provided between the product placement fixture 2 and the base fixture 3. The steel ring is used to position the sound-generating unit in the product positioning groove 21. The steel ring is positioned on the base fixture 3 by the positioning pin 6 and the product placement fixture 2.

[0032] Furthermore, in this embodiment of the invention, base support blocks 4 are respectively provided at the four corners of the base fixture 3 for supporting the base fixture. The base support blocks 4 can be fixed to the base fixture 3 by means of positioning pins. In specific applications, a suitable fixing method can be selected according to the actual situation, and it is not limited to the use of positioning pins for fixing.

[0033] In this embodiment of the invention, the reflow fixture for the sound-generating unit adopts an integrated structure, which can directly support the sound-generating unit. This reflow fixture is equipped with a product positioning groove 21 to ensure accurate placement of the sound-generating unit. The SMT equipment directly picks up the sound-generating unit and places it onto the reflow fixture, then covers it with the top cover 1 for reflow. After reflow, a blue film is used to remove the sound-generating unit from the product placement fixture 2. The blue film is then rotated again for testing. Compared with the traditional sound-generating unit reflow process, this invention's reflow process saves the steps of using a UV film and rotating to a high-temperature film, thus enabling… This invention simplifies the process flow, reduces manual operation steps, and improves production efficiency. It also reduces reliance on various film materials (such as UV film and high-temperature film), significantly lowering material costs by approximately 60%. Furthermore, the reflow fixture for the sound-generating unit provided by this invention exhibits good stability in both high-temperature and cooling zones, preventing deformation and improving the efficiency of subsequent SMT equipment. In summary, the sound-generating unit reflow fixture provided by this invention solves the problems of traditional sound-generating unit reflow processes, such as numerous steps, low efficiency, easy deformation of the fixture, and high costs.

[0034] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model.
