[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. The touch screen works by utilizing the human body's current induction. The conductive film in the touch screen needs to be bonded to the flexible circuit board through hot pressing before subsequent processing and use.

[0003] Traditional hot pressing devices often generate a large amount of heat during the hot pressing process between the touch screen and the outside of the flexible circuit board. The pressed touch screen is removed after natural cooling. The natural cooling rate is slow, which greatly reduces production efficiency. In order to ensure the stability of the touch screen, the touch screen is usually placed inside the positioning groove for limitation, which makes it inconvenient to remove the touch screen.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] As attached Figure 1 - Attachment Figure 4 As shown, a hot pressing device for touch screen production includes a base plate 1, a support frame 2 is installed on the lower side of the base plate 1, a U-shaped groove 8 is installed on the upper side of the base plate 1, a heating box body 6 that moves up and down is provided above the U-shaped groove 8, a heat conducting plate 7 is installed through the lower side of the heating box body 6, a heating box body 2 9 is installed at the bottom of the U-shaped groove 8, a side plate 10 is provided on the notch side of the U-shaped groove 8, a limiting block 11 is installed on one side of the side plate 10, a heat conducting placement plate 12 in contact with the upper side of the heating box body 2 9 is installed on one side of the limiting block 11, two groups of grooves 16 are respectively provided on the inner walls on opposite sides of the U-shaped groove 8, a three-way pipe 19 is connected between the bottoms of the two groups of grooves 16 on one side, a fan 18 connected to the three-way pipe 19 is installed through the base plate 1, and a plurality of air inlet holes 17 are respectively provided at the bottoms of the two groups of grooves 16 on the other side.

[0028] Through the above structure, when the touch screen is heat-pressed, the touch screen is placed on the upper side of the heat-conducting placement plate 12, and the heat-conducting placement plate 12 is placed on the upper side of the heating box body 2 9. By pushing the side plate 10, the heat-conducting placement plate 12 and the touch screen are sent to the inside of the U-shaped groove 8. The side plate 10 and the U-shaped groove 8 form a rectangular structure, and the heating wire inside the heating box body 1 6 and the heating box body 2 9 is heated, and the heat is transferred to the heat-conducting plate 7 and the heat-conducting placement plate 12 respectively. The heating box body 1 6 and the heat-conducting plate 7 move downward, and the outer wall of the heating box body 1 6 contacts the inner wall of the U-shaped groove 8, thereby reducing heat loss during heat pressing. The touch screen is heat-pressed through the heat-conducting plate 7 and the heat-conducting placement plate 12;

[0029] After hot pressing, the heating box body 16 and the heat conducting plate 7 slowly move upward, the groove 16 is connected to the inside of the fan 18, and the fan 18 is started. The heat inside the U-shaped groove 8 is extracted through the fan 18 and the three-way pipe 19, and the air is sent into the U-shaped groove 8 through the multiple groups of air inlet holes 17. The air inside the U-shaped groove 8 flows rapidly, and the touch screen is quickly cooled. The specific structure is as follows:

[0030] Combined with attachment Figure 1 and attached Figure 2 As shown, an inverted L-shaped frame 3 is installed on one side above the base plate 1, and a hydraulic rod 4 is installed through the top of the L-shaped frame 3. The lower end of the hydraulic rod 4 is fixedly connected to the upper side of the heating box body 6, and a temperature monitor 5 is installed on the upper side of the heating box body 6.

[0031] A controller 22 is installed on one side wall of the L-shaped frame 3, and the controller 22 is connected to the temperature monitor 5, the heating box body 1 6, the heating box body 2 9 and the fan 18 respectively.

[0032] Through the above structure, the temperature monitor 5, heating box body 1 6, heating box body 2 9 and fan 18 are controlled by the controller 22. The controller 22 controls the extension and retraction of the hydraulic rod 4, and drives the heating box body 1 6 to move up and down through the hydraulic rod 4. Temperature sensors are respectively provided inside the heating box body 1 6 and the heating box body 2 9. The temperature monitor 5 detects the internal temperature of the heating box body 1 6 and the heating box body 2 9 in real time, and transmits the temperature data to the controller 22. The controller 22 controls the heating temperature of the heating wire inside the heating box body 1 6 and the heating box body 2 9.

[0033] Combined with attachment Figure 4 As shown, support bars 13 are respectively installed on the two opposite edges of the lower side of the heat-conducting placement plate 12, and the support bars 13 are located on both sides of the heating box body 9.

[0034] Through the above structure, the heat-conducting placement plate 12 is supported by the support bar 13. When the heating box body 1 6 and the heat-conducting plate 7 move downward and press on the touch screen, the pressure on the heat-conducting placement plate 12 is prevented from acting on the heating box body 2 9, thereby protecting the heating box body 2 9.

[0035] Example 2

[0036] Based on the first embodiment, please refer to the attached Figure 3 and attached Figure 4 Connecting bolts 14 are respectively passed through the two sides of the side plate 10, and threaded holes 15 for inserting the connecting bolts 14 are respectively provided on the two side walls of the U-shaped groove 8. A handle 23 is installed on the side of the side plate 10 away from the U-shaped groove 8.

[0037] A second groove 20 is provided in the middle of a side of the limiting block 11 away from the side plate 10 , and a plurality of second air inlet holes 21 pass through the bottom of the second groove 20 and the side plate 10 .

[0038] Through the above structure of Example 2, after the side panel 10 pushes the heat-conducting placement plate 12 and the touch screen into the U-shaped groove 8, the connecting bolt 14 is rotated and inserted into the corresponding threaded hole 15 to fix the position of the heat-conducting placement plate 12 and the touch screen, and the side panel 10 is easily pulled through the handle 23.

[0039] The air flow rate inside the U-shaped groove 8 is increased by the plurality of second air inlet holes 21 inside the second groove 20 , thereby quickly reducing the temperature inside the U-shaped groove 8 and cooling the touch screen.
