DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0031] In the prior art, sheet-to-sheet mounting is generally performed manually or using high-end equipment. Manual mounting is inefficient, while high-end equipment mounting is costly.

[0032] The embodiment of the utility model provides a sheet-to-roll material transfer device, which utilizes a rolled adhesive film 10 to adhere a plurality of sheet materials to its surface for easy transmission, thereby improving mounting efficiency while ensuring mounting accuracy.

[0033] A sheet material transfer and coiling device according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0034] Specifically, if Figure 1 As shown, an embodiment of the present invention provides a sheet material transfer device, which (hereinafter sometimes also referred to as a device) includes a rolled adhesive film 10, a material roller assembly and a accommodating box assembly.

[0035] The rolled adhesive film 10 is used to adhere the sheet a, that is, one side of the rolled adhesive film 10 is sticky, and the sheet a can be adhered to the surface thereof.

[0036] The rolled adhesive film 10 is sleeved on the material roller assembly, and is retracted and released under the action of the material roller assembly.

[0037] The storage box assembly includes a storage box 320 and a sliding member 310, wherein the storage box 320 is connected to the sliding member 310, and the storage box 320 is used to place a plurality of flexible sheets a. Under the action of the sliding member 310, the storage box 320 can contact or move away from the adhesive film 10 retracted on the material roller assembly so that the sheets a are adhered to the surface of the adhesive film 10.

[0038] The material roller assembly includes a feed roller 210, a take-up roller and multiple tension rollers. The rolled adhesive film 10 is mounted on the feed roller 210. The end of the rolled adhesive film 10 is connected to the take-up roller. The adhesive film 10 is conveyed under the action of the feed roller 210, the take-up roller and multiple tension rollers.

[0039] It should be noted that the material roller assembly in the embodiment of the present application is not always in a conveying state. The material roller assembly actually stops moving after conveying a certain length of the adhesive film 10. In the stopped state, the sliding member 310 is used to drive the storage box 320 to move toward the adhesive film 10 so as to stick the sheet a in the storage box 320 to the surface of the adhesive film 10.

[0040] It should also be noted that the sheet a in the embodiment of the present application is a sheet a of a flexible material, that is, an adhesive used to be mounted between the support frame and the screen. Before the support frame and the screen are mounted, the two sides of the adhesive are protected by a backing paper or a backing film and a release paper or a release film respectively.

[0041] like Figure 1 As shown, the storage box 320 is driven by the sliding member 310 along Figure 1 It makes reciprocating motion in the direction of the arrow s.

[0042] Specifically, when the material roller assembly stops moving, nothing is pasted on the surface of the adhesive film 10 at the relative position of the storage box 320. The sliding member 310 is used to drive the storage box 320 to move toward the adhesive film 10 and make the sheet a in the storage box 320 contact the surface of the adhesive film 10. The adhesive film 10 adheres to the sheet a in the storage box 320. The storage box 320 moves to the original position, that is, away from the adhesive film 10, driven by the sliding member 310. At this time, the sheet a at the end of the storage box 320 is separated from the storage box 320 and adhered to the surface of the adhesive film 10. The adhesive film 10 stops after moving a distance under the action of the material roller assembly. The moving distance is greater than the length of the sheet a. The distance between adjacent sheets a on the adhesive film 10 can be set according to specific circumstances, and the embodiment of the present application does not limit it.

[0043] In one embodiment, if Figures 1 to 3 As shown, the storage box 320 includes a box body 321 with a top opening, and the top opening extends to the first side wall of the box body 321 to form a hollow area, the area of ​​the hollow area is smaller than the area of ​​the first side wall of the box body 321, and the hollow area is arranged opposite to the adhesive film 10.

[0044] That is, when the sheet a in the storage box 320 moves to contact the surface of the adhesive film 10, the sheet a at the end moves out of the box body 321 from the hollow area and adheres to the surface of the adhesive film 10. The area of ​​the hollow area is smaller than the area of ​​the first side wall of the box body 321, so that the sheet a in the box body 321 can be prevented from being separated from the box body 321 without the action of external force. When the outermost sheet a in the box body 321, that is, the sheet a closest to the first side wall of the box body 321, is deformed and separated from the box body 321 under the action of the external force of the adhesive film 10.

[0045] In one embodiment, if Figure 2 and Figure 3 As shown, the box body 321 includes two blocking blocks 3211, which are respectively located at the two ends of the first side wall of the box body 321 and are respectively connected to the other two side walls of the box body 321. When the sheet a is located in the box body 321, the two blocking blocks 3211 abut against the surface of the sheet a.

[0046] That is to say, the sheet a in the box body 321 is blocked by the blocking blocks 3211 located at both ends of the first side wall of the box body 321. When the adhesive film 10 is adhered to the surface of the sheet a and the box body 321 moves away from the adhesive film 10 driven by the sliding member 310, the sheet a is deformed and separated from the box body 321 under the blocking of the blocking blocks 3211.

[0047] The size and shape of the blocking block 3211 can be set according to specific circumstances, and the embodiment of the present application does not limit this, with the premise that the sheet a can be smoothly separated from the box body 321 when the sliding member 310 drives the box body 321 to move away from the adhesive film 10.

[0048] In a preferred embodiment, if Figure 1 As shown, the tension roller includes a first tension roller 220 and a second tension roller 230, and the adhesive film 10 between the first tension roller 220 and the second tension roller 230 is parallel to the first side wall of the box body 321, that is, parallel to the surface of the sheet a in the box body 321. The first tension roller 220 and the second tension roller 230 are parallel to the first side wall of the box body 321, which can increase the contact area between the sheet a in the box body 321 and the adhesive film 10, thereby improving the pasting effect.

[0049] In one embodiment, if Figure 1 and Figure 4 As shown, the storage box 320 also includes an automatic pressing member 322, and the automatic pressing member 322 includes a pressing plate 3221 and an elastic member, one end of the elastic member is connected to the pressing plate 3221, and the other end is connected to the box body 321, and the pressing plate 3221 is located at the end of the plurality of sheets a. The pressing plate 3221 is pressed against the plurality of sheets a under the action of the elastic member so that the surface of the sheet a is perpendicular to the top opening of the box body 321.

[0050] That is to say, as the sheet a in the box body 321 is continuously reduced, the automatic pressing member 322 can make the surfaces of the multiple sheets a in the box body 321 perpendicular to the top opening of the box body 321, that is, the surface of the sheet a is parallel to the first side wall surface of the box body 321, so that the adhesive film 10 can contact a larger area of ​​the surface of the sheet a, thereby improving the pasting effect and further improving the mounting efficiency.

[0051] One end of the elastic member is connected to the pressure plate 3221, and the other end can be connected to the first side wall of the box body 321, or can be connected to the second side wall opposite to the box body 321. The embodiment of the present application is not limited to achieve that the pressure plate 3221 can always be in contact with the surface of the sheet a.

[0052] In a specific embodiment, if Figure 4 As shown, one end of the elastic member is connected to the pressing plate 3221, and the other end is connected to the first side wall of the box body 321. The elastic member includes a first spring 3222 and a second spring 3223, one end of the first spring 3222 and the second spring 3223 are respectively connected to the two ends of the pressing plate 3221, and the other ends of the first spring 3222 and the second spring 3223 are respectively connected to the two side edges of the first side wall of the box body 321.

[0053] A groove (not shown in the figure) is opened on the side wall of the box body 321, and the first spring 3222 and the second spring 3223 are located in the groove. When one piece of sheet a in the box body 321 is reduced, the pressure plate 3221 moves under the action of the rebound force of the first spring 3222 and the second spring 3223, so that the pressure plate 3221 can always abut against the surfaces of multiple sheets a, and further make the surfaces of multiple sheets a always perpendicular to the opening of the box body 321 or the bottom surface of the box body 321.

[0054] The first spring 3222 and the second spring 3223 are simultaneously connected to the two ends of the pressing plate 3221 to improve the force uniformity of the pressing plate 3221, thereby further improving the force uniformity of the plurality of sheets a.

[0055] In one embodiment, the sheet material conversion device further includes a frame (not shown in the figure), and the frame cover is arranged on the material roller assembly and the accommodating box assembly to improve the integrity of the device and prevent dust from entering the device.

[0056] In one embodiment, the sliding member 310 includes a first driving member, a slider and a slide rail. The first driving member and the slide rail are installed on the inner wall of the frame. The slider is slidably connected to the slide rail. The slider reciprocates along the slide rail under the driving force of the first driving member.

[0057] The first driving component is preferably a linear motor, but is not limited thereto. The first driving component may also be other driving components such as a screw rod.

[0058] Two ends of the slide rail are located on two sides of the adhesive film 10 respectively.

[0059] That is to say, the box body 321 moves to contact the surface of the adhesive film 10 under the drive of the sliding member 310. Since the adhesive film 10 is made of flexible material, the box body 321 will move a longer distance to allow the sheet a to adhere to the surface of the adhesive film 10, thereby improving the adhesion effect between the sheet a and the adhesive film 10.

[0060] In one embodiment, the accommodating box assembly further includes a connecting plate (not shown in the figure), one end of the connecting plate is connected to the box body 321, and the other end is connected to the slider, and the box body 321 follows the slider to reciprocate along the slide rail under the driving force of the first driving member, so that the first side wall of the box body 321 contacts or moves away from the adhesive film 10.

[0061] In one embodiment, if Figure 1 As shown, the sheet material conversion device also includes a baffle 40, one end of which is connected to the frame, the baffle 40 is arranged opposite to the first side wall of the box body 321, the baffle 40 matches the hollow area, and the adhesive film 10 is located between the box body 321 and the baffle 40.

[0062] Because the adhesive film 10 is flexible, when the sheet a in the box body 321 contacts the surface of the adhesive film 10 driven by the sliding member 310, the force between the adhesive film 10 and the sheet a is limited. However, when the sheet a in the box body 321 contacts the surface of the adhesive film 10 and abuts against the surface of the baffle 40 driven by sliding, a greater force is generated between the adhesive film 10 and the sheet a, which improves the adhesion firmness between the sheet a and the adhesive film 10 and further improves the mounting efficiency.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
