DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please also read Figure 1 The present invention provides a pressing mechanism, which includes a pressing head unit 1 and a platform unit 2.

[0028] Please also read Figure 2-Figure 4The pressure head unit 1 includes a pressure head 11, and the pressure head 11 includes a first connecting portion 111 and a second connecting portion 112 arranged in parallel. The pressure head 11 has a first heating portion 113, and the first heating portion 113 is located above the second heating portion 2131. The two ends of the first heating portion 113 are respectively connected to the first connecting portion 111 and the second connecting portion 112; a first inclined portion 114 is provided below the first connecting portion 111, and a second inclined portion 117 is provided below the second connecting portion 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 portion 111 and the second connecting portion 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 portion 111 and the second connecting portion 112. According to the size of the product bonding area, the second working plane 110 of the first heating part 113 can be made wider or narrower through the first inclined surface 114 and the second inclined surface 117. The first heating part 113 and the second heating part 2131 are made of high resistance materials, such as titanium alloy, and 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 the current is transmitted to the first heating part 113 and the second heating part 2131, the resistance of the first connecting part 111 and the third connecting part 2132 is smaller than that of the first heating part 113 and the second heating part 2131 under the condition of constant current. The current passing through the resistance of the first heating part 113 and the second heating part 2131 consumes electrical energy and converts it into heat energy, thereby completing the rapid heating of the first heating part 113 and the second heating part 2131.

[0029] The first connection part 111 and the second connection part 112 are arranged vertically and parallelly, and the first conductive member 12 and the second conductive member 13 are respectively arranged on the outer sides of the first connection part 111 and the second connection part 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 connection part 111 and the second connection part 112 are arranged vertically and parallelly, the first connection part 111 is provided with a plurality of fourth mounting holes 116, and the second connection part 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 in 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 a mounting channel of the first fixing member, and then after the first fixing member as a whole passes through the second mounting hole 131, 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, so as to fix and conductively connect 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, so as to fix and conductively connect 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 purpose, 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 first connecting part 111 that is higher than the second connecting part 112. Then, during assembly, the first fixing part can directly penetrate 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 the components around the pressure head 11.

[0030] 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.

[0031] 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 air outlet direction of the first air hole and the second air hole 133 is toward the first heating portion 113. The first air hole and / or the second air hole 133 selectively supply air to intermittently dissipate heat and cool the pressure head 11. When heat dissipation is required, the control end starts to use air, and the air is transported to the first air hole and the second air hole 133 through two air pipes to prevent the product from being overheated and scalded, and also to prevent the temperature of the parts from being too high.

A third temperature monitoring member 2211 of the platform 221 is embedded in the middle of the platform 221; multiple FPC support rods 2212 for supporting FPC are also arranged on both sides of the platform 221, and the FPC support rods 2212 are connected by FPC support plates 2213, and multiple adjustment holes 2214 are arranged on the FPC support rods 2212, and the FPC support plates 2213 are fixed through the adjustment holes 2214.

[0033] 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 match the length and width of the product. The positioning member 223 is used to limit the length and width of the product to prevent the product from shifting. The FPC support plate 2213 is adjusted forward and backward on the FPC support rod 2212 according to the length of the FPC. Specifically, the FPC support plate 2213 is provided with waist-shaped grooves near the two 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 FPC support plate 2213 is fixed by passing the bolt through the waist-shaped groove and screwing it into the corresponding adjustment hole 2214; in addition, in this embodiment, the cooling element can be preferably a semiconductor refrigerator, 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.

[0034] Please also read 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, 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, 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, the third connecting portion 213 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. A reinforcement area 2135 is provided between the third connecting part 2132 and the fourth connecting part 2133. The reinforcement material is filled in the reinforcement area 2135, and solid glue can be preferably stuffed in it. The solid glue is solidified and formed, and the bonding force becomes larger.

[0035] The third connection part 2132 is provided with a plurality of sixth mounting holes in parallel, the third conductive member 211 is provided with a plurality of seventh mounting holes 2111 in parallel, a plurality of eighth mounting holes 2112 are provided in parallel below the seventh mounting holes 2111, the fourth connection part 2133 is provided with a plurality of ninth mounting holes, the fourth conductive member 212 is provided with a plurality of tenth mounting holes, the sixth mounting hole is coaxially arranged with the seventh mounting hole 2111, the eighth mounting hole 2112 is coaxially arranged with the ninth mounting hole and the tenth mounting hole, and 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 thread of the sixth mounting hole to connect the third connection part 2132 with 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 in the tenth mounting hole to connect the fourth connection part 2133 with the fourth conductive member 212. Thus, a closed-loop current is formed to prevent the current from flowing out.

[0036] 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.
