[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0040] See also Figure 1-Figure 6 The present embodiment provides a precision hot pressing molding device for a flexible transparent display screen, comprising: a main frame 100, a transformer 200 is fixed to one side of the top of the main frame 100, a base 300 is fixed to the other side of the top of the main frame 100, a lower hot pressing mold 400 is fixed to the upper surface of the base 300, both sides of the lower hot pressing mold 400 are internally threadedly connected with threaded rods 420, and rubber pressing plates 430 are fixed to the opposite sides of the two threaded rods 420, and the rubber pressing plates 430 can be controlled by rotating the threaded rods 420. The movement of the rubber pressing plate 430 is used to achieve the clamping effect. The sides of the two rubber pressing plates 430 are fixed with positioning slide bars A440 that penetrate through and are slidably connected to the inside of the lower hot pressing mold 400. The positioning slide bars A440 are designed to position the horizontal movement of the rubber pressing plates 430. The inner wall of the lower hot pressing mold 400 is fixed with a tooth group 410. The upper surface of the base 300 is equipped with an electric telescopic rod 500 through a slider bracket 900, and the bottom extension rod of the electric telescopic rod 500 is equipped with an upper hot pressing mold assembly 600.

[0041] The upper hot pressing mold assembly 600 includes an upper hot pressing mold 610, and a heater 620 is installed inside the upper hot pressing mold 610. The heater 620 is electrically connected to the transformer 200, and the heating area of ​​the heater 620 faces downward. Two groups of oblique pressing components 630 are symmetrically installed inside the upper hot pressing mold 610.

[0042] The oblique pressing assembly 630 includes a three-way hydraulic chamber 631, one end of which is slidably connected to a pressure rod 632 by a piston, and the initial position of the bottom of the pressure rod 632 is lower than the lower surface of the upper hot pressing mold 610. The other two ports of the three-way hydraulic chamber 631 are slidably connected to arc-shaped hydraulic rods 633 by pistons, and a rotating rod 634 is passed through and rotatably connected between the two arc-shaped hydraulic rods 633. A rubber pressure roller 635 is sleeved on the outer side of the rotating rod 634, and gears A636 are fixed on both sides of the rotating rod 634. Two arc-shaped rack rods 637 meshing with the two gears A636 are fixed on the outer side of the three-way hydraulic chamber 631.

[0043] By setting up a lower hot pressing mold 400 to cooperate with the upper hot pressing mold assembly 600, the problem that although the prior art uses a conventional hot pressing structure for hot pressing operations, when hot pressing a curved screen device, the curved area is extremely difficult to press, which will produce a hot pressing blind area and thus lead to incomplete hot pressing is solved. By cooperating with the two oblique pressing assemblies 630 in the upper hot pressing mold assembly 600, when pressing the curved screen, its curved part can be better continued to be hot pressed, thereby improving the comprehensiveness of the hot pressing.

[0044] When the above-mentioned device is used, the mounting base of the flexible transparent display screen is first placed inside the lower hot pressing mold 400, and then the two threaded rods 420 are rotated at the same time. Under the action of the two threaded rods 420, the two rubber pressing plates 430 are pushed synchronously to squeeze the two side parts of the mounting base of the flexible transparent display screen respectively, and then the adhesive is applied, and then the flexible transparent display screen is placed above the mounting base of the flexible transparent display screen. At this time, the preliminary positioning and clamping and the assembly of the flexible transparent display screen are completed.

[0045] Next, the electric telescopic rod 500 and the heater 620 are started, and the upper hot pressing mold assembly 600 is pushed downward as a whole by the electric telescopic rod 500. Since the bottom of the pressure rod 632 in the two sets of oblique pressing assemblies 630 is lower than the bottom of the upper hot pressing mold 610, the pressure rod 632 will first contact with the inside of the lower hot pressing mold 400, thereby being squeezed. At this time, since the pressure rod 632 is squeezed, the liquid pressure inside the three-way hydraulic chamber 631 will increase, thereby simultaneously pushing the two arc-shaped hydraulic rods 633 out, thereby driving the rotating rod 1 634 and the rubber pressure roller 635 to make an arc movement. As the electric telescopic rod 500 is pressed downward, the upper hot pressing mold 610 and the two rubber pressure rollers 635 will first contact To the upper surface of the flexible transparent display screen, as the downward pressure continues, the rubber pressure roller 635 will continue to make an arc movement to squeeze the edge area of ​​the flexible transparent display screen. At the same time, due to the extension of the arc hydraulic rod 633, the gear A636 will rotate under the action of the arc rack rod 637, thereby driving the rotating rod 1 634 and the rubber pressure roller 635 to rotate, so that the rubber pressure roller 635 squeezes the side of the flexible transparent display screen in a rotating manner to prevent friction damage. After a certain period of hot pressing, the upper hot pressing mold assembly 600 is driven to move upward as a whole through the electric telescopic rod 500, and then the threaded rod 420 is rotated in the opposite direction to release the clamping effect of the rubber pressure plate 430, and finally the hot pressed product is taken out.

[0046] Example 2

[0047] See also Figure 1-Figure 8 On the basis of Example 1, a cleaning assembly 700 is installed on the outer side of the lower hot pressing mold 400, and the cleaning assembly 700 includes a four-way hydraulic chamber 710 installed on the outer side of the base 300, and a slider 760 slidably connected to the upper surface of the lower hot pressing mold 400. The two middle ports of the four-way hydraulic chamber 710 are both piston-slidingly connected to a multi-stage hydraulic rod A720, and the two side ports of the four-way hydraulic chamber 710 are both piston-slidingly connected to a multi-stage hydraulic rod B740. The top ends of the two multi-stage hydraulic rods A720 are fixed with connecting plates 730, and the connecting plates 730 are fixed to the side of the upper hot pressing mold 610. The slider 760 There are two sliders 760 in total, both of which are slidably connected to the upper surface of the lower hot pressing mold 400. The two sliders 760 are respectively connected to the two multi-stage hydraulic rods B740. A rotating rod 770 is rotatably connected between the two sliders 760. A cleaning brush 780 is slidably sleeved on the outer side of the rotating rod 770. A gear B790 is fixed to the outer side of the rotating rod 770. The gear B790 is meshed with the tooth group 410. A positioning slide bar B750 is fixed between every two slider brackets 900. The two sliders 760 are respectively penetrated and slidably connected to the two positioning slide bars B750. A spring is fixed between the two sliders 760 and the slider bracket 900.

[0048] The present application provides a cleaning component 700 to clean the dust on the surface of the mounting base of the flexible transparent display screen, thereby preventing dust or debris from remaining inside the base and affecting the fitting effect of the flexible transparent display screen.

[0049] When the above-mentioned device is used in practice, after the two rubber pressure plates 430 squeeze the two side parts of the mounting base of the flexible transparent display screen respectively, without starting the heater 620, the electric telescopic rod 500 is started, and the two multi-stage hydraulic rods A720 are squeezed simultaneously through the connecting plate 730. At this time, the liquid in the multi-stage hydraulic rod A720 will all enter the four-way hydraulic warehouse 710. At this time, the two multi-stage hydraulic rods B740 will gradually extend, and then push the two sliders 760 to slide at the same time. The sliding of the slider 760 will drive the cleaning brush 780 to move through the rotating rod 2 770. At the same time, as the rotating rod 2 770 moves, the gear B790 fixed on its side will rotate under the action of the tooth group 410, and then drive the cleaning brush 780 to rotate through the rotating rod 2 770. At this time, the cleaning brush 780 in the lateral moving and rotating state will clean the upper surface of the mounting base of the flexible transparent display screen, and then perform glue dispensing and covering and bonding of the flexible transparent display screen, and then perform the hot pressing operation as in Example 1.

[0050] Example 3

[0051] See also Figure 1-Figure 10 On the basis of Example 2, the lower hot pressing mold 400 is equipped with a lifting assembly 800, and the lifting assembly 800 includes a four-way air pressure chamber 810 fixed inside the lower hot pressing mold 400, and the two ports of the four-way air pressure chamber 810 are piston-slidingly connected with air pressure rod 1 820, and the other two ports of the four-way air pressure chamber 810 are piston-slidingly connected with air pressure rod 2 830, and the tops of the two air pressure rods 2 830 are fixed with rubber plates 840, and the interior of the lower hot pressing mold 400 is provided with a rectangular groove adapted to the rubber plate 840, and the two air pressure rods 1 820 are respectively located on the movement tracks of the two positioning slide bars A440. By setting the lifting assembly 800, the present application can link the rubber plate 840 to move upward through the rotation of the threaded rod 420, lift the hot-pressed product, and facilitate taking.

[0052] When the above-mentioned equipment is used in practice, after the hot pressing operation is completed, since the threaded rod 420 needs to be rotated in the opposite direction to move in the opposite direction when taking out the finished product, the positioning slide rod A440 moving in the opposite direction will squeeze the pneumatic rod 820. At this time, the gas pressure in the four-way pneumatic warehouse 810 becomes larger, causing the two pneumatic rods 830 to move upward at the same time, pushing the rubber plate 840 to move upward, lifting the hot-pressed product for easy removal.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
