[0034] Embodiment 1

[0035] like Figure 1 and 2 As shown, a touch screen separation device comprises:

[0036] A conveying platform 1, used for conveying the touch screen to be separated;

[0037] A separation component 3 is disposed above the conveying platform 1, and the separation component 3 includes a cutting line 32 and support columns 31 on both sides; the support columns 31 are disposed on both sides of the conveying platform 1, and the cutting line 32 is located above the conveying platform 1 and is disposed on the support columns 31;

[0038] The cutting wire 32 can be heated by supplying electricity.

[0039] Among them, the touch screen separation device also includes a cooling chamber 2, which is arranged above the conveying platform 1, and the cooling chamber covers the separation component 3; the surface of the conveying platform 1 is detachably provided with a fixing groove 4, the bottom surface of the fixing groove 4 is hollowed out and the bottom surface corresponds to the conveying platform 1 and is provided with a hollow 41.

[0040] In the utility model, a detachable fixing groove 4 is provided on the conveying platform 1 for fixing the touch screen to be separated. When the conveying platform 1 moves forward, a hollow 41 is provided at the bottom of the fixing groove 4 and the corresponding conveying platform area. The suction cup 5 further fixes the touch screen to be separated by negative pressure adsorption through the hollow 41. The touch screen to be separated enters the cooling chamber 2 and the electrically heated cutting line 32 softens the glue between the touch screen and the display screen, thereby completing the separation of the display screen and the touch screen. After the separation is completed, the temperature is reduced and cooled through the air jet hole 21 of the cooling chamber 2, thereby preventing the optical glue between the touch screen and the display screen from melting and gluing again, reducing the separation time and improving the separation efficiency.

[0041] In this embodiment, the diameter of the cutting wire 32 is preferably 0.05-0.1 mm, and the temperature of the cutting wire 32 is controlled at 80-90 degrees. Preferably, the cutting wire 32 is a metal copper wire.

[0042] Embodiment 2

[0043] like Figure 3 As shown, the support column 31 includes a slider 311 and a control system, which are not shown in the figure. The sliders 311 on both sides of the support columns 31 respectively fix the two ends of the cutting line 32. The slider 311 can slide up and down along the support column 31 to adjust the height of the cutting line 32. The slider 311 is connected to the control system. The control system adjusts the height of the cutting line 32 by adjusting the height of the slider 311, and electrically heats the cutting line 32.

[0044] The slider described in this example uses high temperature resistant insulating materials, such as ceramics, silicon carbide, aluminum oxide, etc. These materials have excellent high temperature resistance and good insulation properties, and can maintain stable performance in high temperature environments. Ceramic materials have excellent wear resistance and chemical stability, and are suitable for friction and wear environments at high temperatures. Silicon carbide has high hardness and high temperature resistance, and can maintain stable friction characteristics at high temperatures. Alumina has good insulation and high temperature resistance, and is suitable for insulation and support applications at high temperatures. The selection of these materials can ensure that the slider has good wear resistance and insulation properties in high temperature environments, and is suitable for various industrial applications in high temperature environments.

[0045] Through the above structure, the slider 311 can realize vertical movement along the cutting line 32, and can realize precise position adjustment through the control system. Such a design can ensure that the cutting line 32 maintains a stable position during the cutting process, thereby improving the cutting accuracy and efficiency. At the same time, the control system can also realize automatic operation, reduce manual intervention, and improve production efficiency.

[0046] like Figure 5 As shown, a suction cup 5 is provided below the conveying platform 1 , and the suction cup 5 is adsorbed on the bottom surface of the fixing groove 4 through the hollow 41 of the conveying platform 1 , and a base 6 is provided at the bottom thereof.

[0047] Furthermore, the suction cup 5 is connected to the base 6 through a sliding bearing 51, and the suction cup 5 is externally connected to a negative pressure device 7. The function of the suction cup 5 is to generate negative pressure through the negative pressure device 7, thereby adsorbing and fixing the conveying object. The base 6 is used to support and stabilize the position of the suction cup 5. The connection method of the sliding bearing 51 can make the suction cup 5 flexibly move on the base 6 to adapt to the conveying object at different positions. The design of the entire structure can effectively realize the function of fixing and conveying the object above the conveying platform 1.

[0048] It should be noted that the negative pressure device 7 is a device that absorbs objects by the negative pressure principle. It is usually composed of an air pump or a fan, a pipe system and a suction head. When the negative pressure device 7 is started, the air pump or the fan will generate negative pressure, so that the pressure in the suction cup 5 is lower than the external atmospheric pressure. This negative pressure will cause the surrounding air and objects to be absorbed onto the suction cup 5.

[0049] Furthermore, the suction cup 5 is adsorbed on the touch screen on the conveying platform 1 , and the suction cup 5 can slide with the conveying platform 1 until the touch screen is separated and the adsorption is disconnected, and the suction cup 5 moves with the conveying platform 1 in the sliding area 52 .

[0050] The surface of the base 6 is provided with parallel slide rails on both sides, and the suction cup 5 is connected to the slide rails on both sides through a sliding bearing 51. The suction cup 5 slides for a distance along the forward direction of the conveying platform 1 and then detaches, which corresponds to the sliding area 52 on the conveying platform 1, wherein the suction cup 5 slides from the left side of the cutting line 32 to the right side of the cutting line 32 along the forward direction of the conveying platform 1.

[0051] Furthermore, when the suction cup 5 moves from the left side of the sliding area 52 to the right side and separates, it can be pulled back to the left starting position by an elastic rope or a spring to wait for the next touch screen to be adsorbed.

[0052] Furthermore, a hollow area is provided inside the suction cup 5, and the suction cup 5 is externally connected to a negative pressure device 7 through a catheter.

[0053] As another preferred implementation scheme of this embodiment, the catheter interface is arranged on the side of the suction cup 5 adjacent to the slide rail.

[0054] Preferably, the sliding bearing 51 can be configured as an interface connected to a catheter, and in this embodiment, no particular limitation is imposed on the interface position of the suction cup 5 .

[0055] Embodiment 3

[0056] like Figure 4 As shown, the top of the cooling bin 2 is provided with side-by-side jet holes 21, and the jet holes 21 are arranged in a matrix on the top of the cooling bin 2 along the moving direction of the conveyor platform. Further, the jet holes 21 are arranged on the left and right sides of the cutting line.

[0057] Through the above structural design, when the touch screen is sent into the cooling chamber 2, the high-temperature cutting line 32 completes the separation of the display screen and the touch screen, and then the jet hole 21 cools the touch screen, thereby preventing the optical glue between the touch screen and the display screen from melting and gluing again, reducing the separation time and improving the separation efficiency.

[0058] When the utility model works, the cutting line 32 is first powered on for preheating, and then the touch screen is placed in the fixing groove 4 on the conveying platform 1 and pressed tightly, and the conveying platform 1 is turned on. When the fixing groove 4 moves to above the suction cup 5, it is adsorbed and fixed by the suction cup 5. The conveying platform 1 sends the screen into the temperature control warehouse 2. When the touch screen is close to the separation component 3, the cutting line 32 reaches the preset temperature range of 80-90 degrees. The control system adjusts the height of the cutting line 32 by adjusting the height of the slider 311. As the conveying platform 1 moves, the cutting line 32 is separated along the OCA layer of the touch screen. After the separation of the touch screen is completed, cold air is sprayed through the jet hole 21 of the cooling warehouse 2 to cool the touch screen, which can prevent the OCA from fusing together again after high-temperature cutting. Finally, the suction cup 5 disconnects the adsorption and restores the initial position.

[0059] The utility model provides a touch screen separation device, including: a conveying table, used to convey the touch screen to be separated; a separation component, arranged above the conveying table, the separation component including a cutting line and support columns on both sides; the support columns are arranged on both sides of the conveying table, the cutting line is located above the conveying table and arranged on the support columns; the cutting line can be heated when powered on. The present application heats and cuts the glue between the touch screen and the display screen by setting an electric heating cutting line, thereby completing the separation of the display screen and the touch screen, and then cools down after the separation is completed, thereby preventing the optical glue between the touch screen and the display screen from melting and gluing again, reducing the separation time and improving the separation efficiency. The utility model can achieve a stable fixing function when the touch screen is separated by cooperating with the fixing groove and the suction cup on the conveying table, thereby improving the separation efficiency.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
