Description

Technical Field

[0001] The present application relates to a technical improvement for packaging electronic components, and more particularly to a heat-pressing sealing device. Background Art

[0002] The existing hot pressing sealing method is usually used for electronic component packaging. Generally, a hot pressing seat is set up to perform hot pressing and sealing on the material strip with the electronic components embedded in it. The hot pressing seat is equipped with a heater inside, so that the heat energy of the heater is transferred to the hot pressing surface of the hot pressing seat, and then the hot pressing surface is pressed on the material strip. Since the heater is usually set in the center of the hot pressing seat, the heat is diffused from the center to the surrounding area. Therefore, after actual use, it is found that the central position of the hot pressing surface will accumulate too high a temperature compared to the surrounding area, causing the film of the material strip to melt and shrink due to the excessively high temperature during the hot pressing process, or even crack, affecting the packaging quality. In addition, if the area of ​​the hot pressing surface is too large, it may be hot pressed on the electronic components in the material strip at the same time, affecting the quality of the electronic components.

[0003] Therefore, how to improve the heat pressing method is an urgent goal that relevant industries need to work hard on. Utility Model Content

[0004] Therefore, the object of the present application is to provide a heat-compression sealing device that can improve the above-mentioned shortcomings.

The heat-pressing sealing device comprises a support unit pivotally connected to the machine platform and capable of pivoting up and down relative to the machine platform, and a pressing unit disposed on the support unit and capable of pivoting up and down with the support unit. The pressing unit comprises a base coupled to the support unit, a heating element transversely embedded within the base, and a plurality of mutually spaced pressure strips disposed on the base. The pressure strips are used to press against the material strip. The pressure strips extend in the same direction as the heating element, and the front end of the pressing unit protrudes beyond the front end of the support unit.

[0006] Another feature of the present application is that the pressing unit has two pressing strips, which are spaced apart and parallel to each other.

[0007] Another feature of the present application is that each of the pressure strips has a main body portion connected to the base, and a pressing portion extending from the main body portion in a direction away from the base.

[0008] Another feature of the present application is that the cross-sectional width of the main body of each of the pressure strips gradually decreases in a direction away from the base.

[0009] Another feature of the present application is that the cross-sectional width of the pressing portion of each of the pressure strips is the same as the minimum cross-sectional width of the main body.

[0010] Another feature of the present application is that both ends of each of the pressure strips are curved surfaces.

[0011] Another feature of the present application is that the support unit includes two support sheets spaced apart from each other, and the pressing unit is disposed between the two support sheets.

[0012] The beneficial effect of the present application is that the pressure strips of the pressing unit are designed to be spaced apart from each other, which can make the heating and pressing area and heat energy more concentrated, thereby improving the efficiency of hot pressing. At the same time, the spaced design can also avoid electronic components in the material strip, avoiding damage to the electronic components during the hot pressing process.

[0018] The preferred embodiments of the present application are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present application can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the scope of protection of the present application. Before describing in detail, it should be noted that similar components are represented by the same number. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front, back, bottom, top, etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are for illustration, not for limitation of the present application.

[0019] See Figure 1 , a preferred embodiment of the heat-pressing sealing device of the present application, is mounted on a machine 1 and used to seal a material strip 10. The heat-pressing sealing device includes a support unit 2 pivotally connected to the machine 1 and capable of pivoting up and down relative to the machine 1, and a pressing unit 3 disposed on the support unit 2 and capable of pivoting up and down with the support unit 2. The support unit 2 includes two spaced-apart support sheets 21, and the pressing unit 3 is disposed between the two support sheets 21.

[0020] See Figure 2 and Figure 3 ,in, Figure 2 and Figure 3 The pressing unit 3 is turned upside down to facilitate the explanation of its detailed structure. The pressing unit 3 includes a base 31 combined with the support unit 2, a heating element 32 transversely embedded in the base 31, and a plurality of pressure strips 33 arranged on the base 31 and spaced apart from each other, and the pressure strips 33 are used to press onto the material strip 10. The heating element 32 is energized to generate heat energy, and the heat energy is transferred to the pressure strips 33 to perform the heating and pressing process. Therefore, the base 31 is usually made of a material with high thermal conductivity. In this embodiment, there are two pressure strips 33, which are spaced apart and parallel to each other, and the two ends of each pressure strip 33 are curved surfaces. Each pressure strip 33 has a main body 331 connected to the base 31, and a pressing portion 332 extending from the main body 331 in a direction away from the base 31. The cross-sectional width of the main body portion 331 of each of the pressure strips 33 gradually decreases in the direction away from the base 31. Figure 3 As shown, the cross-section of the main body 331 is trapezoidal. The cross-sectional width of the pressing portion 332 of each pressure strip 33 is the same as the minimum cross-sectional width of the main body 331. In other words, the main body 331 extends from the point where the cross-sectional width of the pressing portion 332 is the smallest and then extends away from the base 31. With this design, the contact area between the pressing portion 332 and the material strip 10 can be reduced, and the situation where the material strip 10 has residual adhesive remaining in the pressing portion 332 due to the heat melting during the hot pressing process can be reduced. In addition, the trapezoidal structure of the main body 331 is used to provide structural strength reinforcement.

[0021] In addition, the extension direction of the pressure strip 33 is the same as the extension direction of the heating element 32 and the extension direction of the material strip 10, so the heat energy of the heating element 32 can be more reliably and evenly transferred to the pressure strip 33. Figure 2 As shown, the front end of the pressing unit 3 is structurally designed to protrude from the front end of the supporting unit 2, so that the length of the pressing unit 3 can be lengthened, and the length of the pressure strip 33 can also be lengthened, and the width of the pressing unit 3 can be reduced, thereby increasing the pressing area without increasing the overall weight and improving the working efficiency.

[0022] See Figure 4 , it can be seen that one end of the support unit 2 is pivotally connected to the machine 1, and the pressing unit 3 protrudes from the other end of the support unit 2. When the heating and pressing operation is not performed, the pressing unit 3 and the machine 1 maintain an angle of 15 to 20 degrees. When the heating and pressing operation is to be performed, the support unit 2 will pivot and drive the pressing unit 3 downward to press the material strip 10, as shown in FIG. Figure 5When the pressing is completed, the support unit 2 will drive the pressing unit 3 to return to the position shown in FIG. Figure 4 Position shown.
