DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please also refer to Figure 1 The present invention provides a pressing mechanism, which includes a pressing head unit 1 and a platform unit 2.

[0021] Please also refer to Figure 2-Figure 4The pressure head unit 1 includes a pressure head 11, which includes a first connecting part 111 and a second connecting part 112 arranged in parallel. The pressure head 11 has a first heating part 113, which is located above the second heating part 2131. The two ends of the first heating part 113 are respectively connected to the first connecting part 111 and the second connecting part 112; a first inclined portion 114 is provided below the first connecting part 111, and a second inclined portion 117 is provided below the second connecting part 112. The connecting surface of the first inclined portion 114 and the second inclined portion 117 forms a second working plane 110 of the pressure head 11, and the width of the second working plane 110 is narrower than the width between the first connecting part 111 and the second connecting part 112; the pressure head unit 1 also includes a first conductive member 12 and a second conductive member 13, one end of the first conductive member 12 and the second conductive member 13 are respectively connected to the two poles of the power supply, and the other ends of the first conductive member 12 and the second conductive member 13 are connected to the first connecting part 111 and the second connecting part 112. Depending on the size of the product's bonding area, the second working plane 110 of the first heating portion 113 can be widened or narrowed by the first bevel portion 114 and the second bevel portion 117. The first heating portion 113 and the second heating portion 2131 are made of a high-resistance material, such as a titanium alloy. The first conductive member 12, the second conductive member 13, the third conductive member 211, and the fourth conductive member 212 can be copper. When current is conducted to the first heating portion 113 and the second heating portion 2131, while the current remains constant, the resistance of the first connecting portion 111 and the third connecting portion 2132 is less than that of the first heating portion 113 and the second heating portion 2131. The current passing through the resistance of the first heating portion 113 and the second heating portion 2131 consumes electrical energy and converts it all into heat energy, thereby rapidly heating the first heating portion 113 and the second heating portion 2131.

[0022] The first connecting portion 111 and the second connecting portion 112 are arranged vertically and parallel to each other, and the first conductive member 12 and the second conductive member 13 are respectively arranged on the outside of the first connecting portion 111 and the second connecting portion 112; the first conductive member 12 is provided with a plurality of first mounting holes, and the second conductive member 13 is provided with a plurality of second mounting holes 131 and a third mounting hole 132; the first connecting portion 111 and the second connecting portion 112 are arranged vertically and parallel to each other, the first connecting portion 111 is provided with a plurality of fourth mounting holes 116, and the second connecting portion 112 is provided with a fifth mounting hole 118, and the first mounting hole and the second mounting hole 131 and the fourth mounting hole 116 are located on the same horizontal plane; wherein, the first mounting hole and the fifth mounting hole 118 are threaded holes. In addition, it also includes a first fixing member and a second fixing member, and preferably the first fixing member and the second fixing member are bolts, wherein the inner diameter of the second mounting hole 131 is larger than the maximum outer diameter of the first fixing member, so that the second mounting hole 131 becomes the mounting channel of the first fixing member, and then after the first fixing member passes through the second mounting hole 131 as a whole, the front end passes through the fourth mounting hole 116 and is threadedly connected to the first mounting hole of the first conductive member 12, thereby fixing and conductively connecting the first conductive member 12 to the first connecting portion 111; the second fixing member partially passes through the third mounting hole 132 and is screwed into the fifth mounting hole 118, thereby fixing and conductively connecting the second conductive member 13 to the second connecting portion 112. Furthermore, in order to prevent a short circuit between the first connecting part 111 and the second connecting part 112 due to improper installation as much as possible during the connection process of the first fixing part, and to reduce the inspection and assembly difficulty required for this, in this embodiment, the upper end surface of the first connecting part 111 is preferably higher than the second connecting part 112, and a fourth mounting hole 116 is provided on the portion of the first connecting part 111 that is higher than the second connecting part 112. Then, during assembly, the first fixing part can directly pass through the second mounting hole 131 to connect the first connecting part 111 to the first conductive part 12. The upper end surface of the second connecting part 112 is lower than the upper end surface of the first connecting part 111. This structure perfectly allows the second connecting part 112 to avoid the installation range of the first fixing part, thereby solving this problem, and can maximize the reduction in the size of the pressure head 11 and reduce its occupied space, which is conducive to the miniaturization of the equipment and the layout of components around the pressure head 11.

[0023] A reinforcement area 115 is provided between the first connection part 111 and the second connection part 112, and the reinforcement area 115 is filled with reinforcement material; and a first monitoring component 119 is embedded in the reinforcement area 115, and the solid glue is solidified and formed, and the bonding force becomes stronger; the first monitoring component 119, the second monitoring component, and the third monitoring component 2211 can all be thermocouples.

[0024] The first conductive member 12 is provided with a first air hole, and the second conductive member 13 is provided with a second air hole 133. The first and second air holes 133 direct air toward the first heating portion 113. The first and second air holes 133 selectively supply air, intermittently cooling the pressure head 11. When heat dissipation is required, the control terminal activates air flow, delivering air to the first and second air holes 133 via two air pipes. This prevents product overheating and burns, and also prevents overheating of components.

[0025] Please also refer to Figure 5 In this embodiment, the platform unit 2 includes an auxiliary heating component 21 for the product's bonding area and a platform component 22 with rapid heat dissipation. The platform component 22 is located in front of the auxiliary heating component 21. The platform component 22 includes a platform 221 for placing the product. The platform 221 is provided with product adsorption holes 222 and a positioning member 223. A cooling element is located below the platform 221. The cooling element has a heat dissipation surface and a cooling surface. The heat dissipation surface is in close contact with the bottom surface of the platform 221, and the cooling surface is connected to a heat sink 224. A fan 225 is located below the heat sink 224. A third platform 221 temperature monitoring component 2211 is embedded in the center of the platform 221. Multiple FPC support rods 2212 for supporting the FPC are also located on both sides of the platform 221. The FPC support rods 2212 are connected by FPC brackets 2213. The FPC support rods 2212 are provided with multiple adjustment holes 2214, and the FPC brackets 2213 are fixed through the adjustment holes 2214.

[0026] Place the product on the platform 221 and turn on the vacuum device. The vacuum device is connected to the adsorption hole 222 through a pipeline, so that the adsorption hole 222 adsorbs the product. A plurality of positioning member 223 mounting holes are arranged side by side on the platform 221. There are more than one positioning member 223. According to the product specifications, adjust the positioning member 223 to the corresponding position of the appropriate positioning member mounting hole 2231 to make it adapt to the length and width of the product. The positioning member 223 is used to limit the length and width directions of the product to prevent the product from shifting; the FPC support plate 2213 is adjusted back and forth on the FPC support rod 2212 according to the length of the FPC. Specifically, the FPC support plate 2213 is provided with a waist-shaped groove near both ends. The FPC support plate 2213 is moved along the length direction of the FPC support rod 2212 to change the corresponding relationship between the waist-shaped groove and the adjustment hole 2214 on the FPC support rod 2212, thereby realizing the position of the FPC support plate 2213. Of course, it should be noted that after the position is determined, the bolts are passed through the waist-shaped groove and screwed into the corresponding adjustment holes 2214 to fix the FPC support plate 2213; in addition, in this embodiment, the cooling element can be preferably a semiconductor cooler, and the heat dissipation surface of the cooling element starts to dissipate heat and cool the bottom surface of the platform 221 to prevent the temperature of the platform 221 from being too high.

[0027] Please also refer to Figure 6 The auxiliary heating component 21 includes a pressing platform 213, which includes a second heating portion 2131, a third connecting portion 2132 and a fourth connecting portion 2133 arranged in parallel, a third conductive member 211 and a fourth conductive member 212 outside the third connecting portion 2132 and the fourth connecting portion 2133, the third conductive member 211 and the third connecting portion 2132, and the fourth conductive member 212 and the fourth connecting portion 2133 are connected to each other for electrical conduction, the third connecting portion 2132 is shorter than the fourth connecting portion 2133, the second heating portion 2131 is connected to the upper ends of the third connecting portion 2132 and the fourth connecting portion 2133, and the third connecting portion 2132 is shorter than the fourth connecting portion 2133. 2 and the fourth connecting part 2133 are insulated and are only electrically connected through the second heating part 2131. A second monitoring component for real-time feedback of the temperature of the second heating part 2131 is embedded in the center of the second heating part 2131. The shape of the pressing platform 213 is consistent with the shape of the pressing head 11; the third conductive member 211 and the fourth conductive member 212 clamp the third connecting part 2132 and the fourth connecting part 2133 therebetween, and a reinforcement area 2135 is provided between the third connecting part 2132 and the fourth connecting part 2133. The reinforcement area 2135 is filled with reinforcement material, and solid glue can be preferably stuffed into it. The solid glue is solidified and formed, and the bonding force becomes greater.

[0028] The third connecting portion 2132 has a plurality of sixth mounting holes arranged side by side, the third conductive member 211 has a plurality of seventh mounting holes 2111 arranged side by side, and a plurality of eighth mounting holes 2112 arranged side by side below the seventh mounting holes 2111. The fourth connecting portion 2133 has a plurality of ninth mounting holes, and the fourth conductive member 212 has a plurality of tenth mounting holes. The sixth mounting hole is coaxial with the seventh mounting hole 2111, and the eighth mounting hole 2112 is coaxial with the ninth and tenth mounting holes. The device further includes a third fixing member and a fourth fixing member. The inner diameter of the eighth mounting hole 2112 is greater than the maximum outer diameter of the fourth fixing member. After the third fixing member completely passes through the seventh mounting hole 2111, it partially passes through the portion of the sixth mounting hole and is threadedly connected to the third connecting portion 2132 and the third conductive member 211. After the fourth fixing member completely passes through the eighth mounting hole 2112, it partially passes through the ninth mounting hole and is threadedly connected to the tenth mounting hole, connecting the fourth connecting portion 2133 and the fourth conductive member 212. This forms a closed current loop and prevents current from flowing out.

[0029] The upper end surface of the pressing table 213 is the first working plane 2134, and the lower pressing surface of the pressing head is the second working plane 110. The first working plane 2134 and the upper surface of the platform 221 are on the same horizontal plane. The temperature of the first working plane 2134 is lower than the temperature of the second working plane 110. When the pressing head presses down, the first working plane 2134 collides with the second working plane, thereby realizing auxiliary heating of the pressing table 213.

[0030] Therefore, the present application quickly forms a closed-loop heating and heat dissipation for the first heating part 113 of the pressing head 11 through the first conductive member 12 and the second conductive member 13, and the auxiliary heating component 21 performs auxiliary closed-loop heating and heat dissipation on the second heating part 2131. Therefore, compared with the existing technology of embedding the pressing head 11 through the heating tube, the pressing head 11 of the present application has a faster heating speed and can quickly dissipate heat and cool down after the hot pressing is completed. Furthermore, through the auxiliary heating component 21, the difficulty of temperature control is significantly reduced, which solves the problems of slow hot pressing heating speed, uneven temperature of the second working plane 110 of the pressing head 11, and slow heat dissipation in the existing technology.

For example, they may refer to connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components.
