[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] This application proposes a handle folding device for a protective film, please refer to Figure 1 , including: a heatable roller 10, a bending piece 20, a top plate 30 and a transport line 40. The protective film 60 is provided with a handle 70 at its edge, so that the user can tear off the protective film 60 before use. Among them, the roller 10 is used to heat the connection between the protective film 60 and its handle 70, and the top plate 30 is used to lift the handle 70. The bending piece 20 is used to fold down the handle 70. In production, the protective films 60 are arranged one by one on the transport line 40. The roller 10 is rotatably arranged above the transport line 40, the bending piece 20 is fixed above the transport line 40 and attached to the protective film 60, and the top plate 30 is arranged on the transport line 40. The roller 10, the top plate 30, and the bending piece 20 are arranged in sequence along the transmission direction of the transport line 40. Because the transport line 40 transports the protective film 60 along a certain direction. When the protective film 60 passes under the hob 10, the hob 10 heats the connection between the protective film 60 and its handle 70, so that the connection softens and has better plasticity. The top plate 30 lifts and folds the connection to be perpendicular to the length direction of the protective film 60. The handle 70 is then folded and pressed down toward the surface of the protective film 60 by the pressing plate 22, so that the handle 70 can be folded on the surface of the protective film 60, and the protective film 60 is attached to the touch screen, which can save the space for placing the touch screen and the cost of blistering. And driven by the protective film 60 in transit, the hob 10 rotates along the transmission direction of the transport line 40, and continuously heats the next protective film 60, which is efficient and accurate.
[0025] It should be noted that once the temperature of the connection between the protective film 60 and the handle 70 drops, its folding property is weak and it is difficult to return to its original state at room temperature. In addition, the top plate 30 is tilted on the transport line 40, so that the handle 70 is easier to be lifted up. At the moment when the handle 70 is lifted up, it is bent and folded by the bending member 20, so that the entire protective film 60 will not be lifted up and folded by the bending member 20, thereby improving the folding accuracy.
[0026] In one embodiment, please continue to refer to Figure 1 The hob 10 includes a roller 11, a plurality of heat-conducting plates 12 and a plurality of heating elements. The roller 11 is used to be fixed to the heat-conducting plate 12, and the plurality of heat-conducting plates 12 are arranged on the outer side of the roller 11. The heating element is arranged on the heat-conducting plate 12, and the heating element is used to generate heat to increase the temperature of the heat-conducting plate 12. The heat-conducting plate 12 is used to conduct heat, so that the end of the heat-conducting plate 12 is supported on the surface of the protective film 60, so that the connection between the protective film 60 and its handle 70 is softened, so that the top plate 30 is lifted up and folded, and finally folded and pressed down through the pressing plate 22. Among them, the heating element is a heating resistance wire.
[0027] Specifically, each heat conducting plate 12 is arranged on the roller 11 at equal intervals, so that the heat conducting plate 12 can accurately heat the connection between the protective film 60 and its handle 70, soften the connection between the protective film 60 and its handle 70 of the same specification, and do not require an automatic identification and control device, saving costs.
[0028] Furthermore, the number of the heat conducting plates 12 is four.
[0029] Furthermore, the heat conducting plates 12 have the same length, so that the softening effect of each heat conducting plate 12 on the protective film 60 is the same, and thus the production quality of each protective film 60 is the same.
[0030] In addition, the width of the heat conducting plate 12 is the same as the width of the handle 70 of the protective film 60. The heat conducting plate 12 can fully heat the connection between the protective film 60 and the handle 70, so that the connection between the two is softened, thereby changing the plasticity of the handle 70, so that the handle 70 is folded along the connection line between the handle 70 and the protective film 60.
[0031] In one embodiment, the height of the top plate 30 is greater than the thickness of the protective film 60 , so that the handle 70 can be fully lifted up by the top plate 30 , and then the lifted handle 70 can be folded onto the surface of the protective film 60 by the pressing plate 22 .
[0032] See also Figure 1 A plurality of suction holes 50 are provided on the transport line 40, and the suction holes 50 are connected to a pneumatic device so that a certain suction force is generated on the suction holes 50. The suction holes 50 are used to suck the protective film 60 on the transport line 40 to prevent the protective film 60 from shifting and avoid misalignment of the heating point of the roller 10 on the protective film 60.
[0033] See also Figure 2 The bending member 20 includes a seesaw 21 and a pressure plate 22. The seesaw 21 is tilted upward in a direction away from the protective film 60 and connected to the pressure plate 22. The seesaw 21 is on the side close to the hob 10. The tilting setting of the seesaw 21 is to prevent the protective film 60 from being lifted up by the handle 70 and to prevent the folding position from being wrong, which will cause the protective film 60 to be scrapped. The seesaw 21 presses and bends the handle 70 lifted up by the top plate 30, and the pressure plate 22 completely folds the handle 70 so that the handle 70 fits on the surface of the protective film 60.
[0034] In addition, there are two seesaws 21, which are symmetrically arranged on the same side of the pressure plate 22. The gap between the two seesaws 21 is used to avoid the heat conducting plate 12 of the roller 10, so as to prevent the heat conducting plate 12 from interfering with the seesaw 21 and affecting the operation state of the device.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
