Description

Technical Field

[0001] The present invention relates to the technical field of multimedia interactive intelligent display terminals, and in particular to an educational intelligent interactive flat panel production device and a production process thereof. Background Art

[0002] For multimedia interactive intelligent display terminals such as smart interactive touch tablets, smart screens, smart blackboards, infrared touch screens, capacitive touch screens, capacitive touch screens, and electromagnetic touch screens, the existing technology adopts liquid optical glue & water glue (LOCA & OCA) bonding process. When bonding medium and large-sized TFT-LCD liquid crystal glasses, the optical film (diffuser plate, diffusion film, brightness enhancement film or DOP\DOPP) is under the plastic middle frame, and the TFT-LCD liquid crystal glass is on the plastic middle frame. The TFT-LCD liquid crystal glass and the glass cover with or without touch are completely glued together in a seamless manner with glue to provide better display effects.

[0003] In the production process of gluing the TFT-LCD liquid crystal glass and the glass cover plate together, a layer of glue is first applied between the TFT-LCD liquid crystal glass and the glass cover plate, and then the TFT-LCD liquid crystal glass and the glass cover plate are glued together by pressing. The pressing force needs to be precisely controlled to prevent the glue from overflowing from the edges and causing product defects.

[0004] When the glue overflows, the TFT-LCD liquid crystal glass and the glass cover plate will form a very obvious uneven bonding thickness after bonding. The thickness of the bonding middle part is particularly large, while the bonding thickness of the edge is particularly small, which can easily lead to uneven force on the TFT-LCD liquid crystal glass, which will result in a large amount of process glue, high cost, poor flatness and easy to produce Muar (referring to the uneven brightness of the display, causing various marks). If the pressing force is too small, it is easy to cause the glue to not flow all over the bonding surface after bonding. The uneven glue thickness is very likely to cause yellowing, and the weak glue parts are prone to bubbles and debonding. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an educational intelligent interactive tablet production device and a production process thereof, which, on the one hand, prevents glue from overflowing from the edge sheet, and on the other hand, allows the glue to flow evenly over the entire bonding surface, thereby improving the product yield.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] An educational intelligent interactive flat panel production device, used for pressing liquid crystal glass and glass cover plate, comprising a mobile platform and a pressing mechanism arranged on the mobile platform;

[0008] The pressing mechanism comprises: a base, a support frame, a lifting device, a pressing device, and a loading jig; the support frame is fixed on the base, the loading jig is installed on the base, the lifting device is arranged below the loading jig, and the pressing device is installed on the support frame and located above the loading jig;

[0009] The loading fixture comprises a bottom plate and a frame arranged around the bottom plate, and the bottom plate is provided with through holes and air holes;

[0010] The lifting device includes a lifting drive unit and a lifting plate provided at the output end of the lifting drive unit, wherein the lifting drive unit drives the lifting plate to be lifted and lowered so as to pass through the through hole; the pressing device includes a pressing drive unit and a pressing plate provided at the output end of the pressing drive unit, wherein the pressing drive unit drives the pressing plate to be lifted and lowered so as to be close to or away from the loading fixture;

[0011] When the liquid crystal glass and the glass cover plate are accommodated in the frame, the edges of the liquid crystal glass and the glass cover plate are seamlessly fitted to the frame.

[0012] In one of the embodiments, the pressing device further comprises a pressing guide plate, and the pressing guide plate is slidably disposed on the support frame;

[0013] The pressing plate is arranged on the pressing guide plate through an elastic member.

[0014] In one embodiment, the spring element is a cylindrical spring structure.

[0015] In one embodiment, the lifting drive unit is a motor screw drive structure.

[0016] In one of the embodiments, an inclined guiding surface is provided at the frame.

[0017] In one of the embodiments, a moving wheel set is installed at the bottom of the moving platform.

[0018] In one of the embodiments, a cover is provided on the mobile platform.

[0019] A production process of an educational intelligent interactive tablet is implemented by the above-mentioned educational intelligent interactive tablet production equipment, comprising the following steps:

[0020] The lifting driving unit drives the lifting plate to rise, so that the lifting plate passes through the through hole and reaches the upper part of the loading fixture;

[0021] Placing the liquid crystal glass and the glass cover plate coated with glue on the lifting plate;

[0022] The lifting driving unit drives the lifting plate to descend, and the lifting plate drives the liquid crystal glass and the glass cover plate to descend and press them on the bottom plate. During the descending process of the liquid crystal glass and the glass cover plate, the gas in the frame is discharged through the vent holes. When the liquid crystal glass and the glass cover plate are accommodated in the frame, the edges of the liquid crystal glass and the glass cover plate are seamlessly attached to the frame.

[0023] The pressing driving unit drives the pressing plate to descend, so that the pressing plate applies a pressing force to the liquid crystal glass and the glass cover plate. Since the edges of the liquid crystal glass and the glass cover plate are seamlessly attached to the frame, the glue cannot overflow from the edges of the liquid crystal glass and the glass cover plate.

[0024] Maintaining the pressing force allows the glue to flow evenly on the liquid crystal glass and the glass cover plate. When the preset time threshold is reached, the pressing drive unit drives the pressing plate to rise and move away from the liquid crystal glass and the glass cover plate.

[0025] The lifting driving unit drives the lifting plate to rise again, and the lifting plate pushes the liquid crystal glass and the glass cover plate out of the frame.

[0026] The educational intelligent interactive flat panel production equipment and the production process thereof of the present invention can prevent glue from overflowing from the edge sheet on the one hand, and can make the glue flow evenly over the entire bonding surface on the other hand, thereby improving the product yield.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] like Figure 1 As shown, the present invention discloses an educational intelligent interactive tablet production device 10, which is used to press a liquid crystal glass 20 and a glass cover plate 30, and includes a mobile platform 11 and a pressing mechanism 12 arranged on the mobile platform 11. In this embodiment, a moving wheel set 11a is installed at the bottom of the mobile platform 11, and the entire device can be conveniently moved by setting the moving wheel set 11a; a cover body 11b is also provided on the mobile platform 11, and dust prevention can be better achieved by setting the cover body 11b, thereby improving product quality.

[0038] like Figure 2 As shown, the pressing mechanism 12 includes: a base 100, a support frame 200, a lifting device 300, a pressing device 400, and a loading fixture 500. The support frame 200 is fixed on the base 100, the loading fixture 500 is installed on the base 100, the lifting device 300 is arranged below the loading fixture 500, and the pressing device 400 is installed on the support frame 200 and located above the loading fixture 500.

[0039] like Figure 3As shown, the loading fixture 500 includes a bottom plate 510 and a frame 520 disposed around the bottom plate 510 . A through hole 511 and a vent hole 512 are formed on the bottom plate.

[0040] like Figure 3 As shown, the lifting device 300 includes a lifting drive unit 310 and a lifting plate 320 disposed at the output end of the lifting drive unit 310. The lifting drive unit 310 drives the lifting plate 320 to move up and down to pass through the through hole 511. In this embodiment, the lifting drive unit is a motor screw drive structure.

[0041] like Figure 2 As shown, the pressing device 400 includes a pressing driving unit 410 and a pressing plate 420 disposed at an output end of the pressing driving unit 410 . The pressing driving unit 410 drives the pressing plate 420 to move up and down to approach or move away from the loading fixture 500 .

[0042] When the liquid crystal glass 20 and the glass cover plate 30 are placed in the frame 520, the edges of the liquid crystal glass 20 and the glass cover plate 30 are seamlessly attached to the frame 520. Preferably, an inclined guide surface 521 (such as Figure 3 As shown), in this way, the liquid crystal glass 20 and the glass cover plate 30 can be guided into the frame 520 more smoothly.

[0043] The present invention also discloses a production process of an educational intelligent interactive tablet, which is implemented by the educational intelligent interactive tablet production device 10, and includes the following steps:

[0044] like Figure 4 and Figure 5 As shown, the lifting driving unit 310 drives the lifting plate 320 to rise, so that the lifting plate 320 passes through the through hole 511 and reaches the upper part of the loading fixture 500;

[0045] like Figure 4 and Figure 5 As shown, the liquid crystal glass 20 and the glass cover plate 30 coated with glue 40 are placed on the lifting plate 320;

[0046] like Figure 6 As shown, the lifting driving unit 310 drives the lifting plate 320 to descend, and the lifting plate 320 drives the liquid crystal glass 20 and the glass cover plate 30 to descend and press them on the bottom plate 510. During the descending process of the liquid crystal glass 20 and the glass cover plate 30, the gas in the frame 520 is discharged through the vent holes 512. When the liquid crystal glass 20 and the glass cover plate 30 are accommodated in the frame 520, the edges of the liquid crystal glass 20 and the glass cover plate 30 are seamlessly attached to the frame 520.

[0047] The pressing driving unit 410 drives the pressing plate 420 to descend, so that the pressing plate 420 applies a pressing force to the liquid crystal glass 20 and the glass cover plate 30. Since the edges of the liquid crystal glass 20 and the glass cover plate 30 are seamlessly attached to the frame 520, the glue 40 cannot overflow from the edges of the liquid crystal glass 20 and the glass cover plate 30.

[0048] The pressing force is maintained so that the glue 40 flows evenly on the liquid crystal glass 20 and the glass cover plate 30. When the preset time threshold is reached, the pressing driving unit 410 drives the pressing plate 420 to rise and move away from the liquid crystal glass 20 and the glass cover plate 30.

[0049] The lifting driving unit 310 drives the lifting plate 320 to rise again, and the lifting plate 320 lifts the liquid crystal glass 20 and the glass cover plate 30 out of the frame 520;

[0050] The laminated liquid crystal glass 20 and glass cover plate 30 are taken away, and the next liquid crystal glass 20 and glass cover plate 30 to be laminated are placed on the lifting plate 320 again, and the above-mentioned actions are repeated.

[0051] In the present invention, it is mainly to ensure that the edges of the liquid crystal glass 20 and the glass cover plate 30 are seamlessly attached to the frame 520. In the process of processing the loading jig 500, a high-precision CNC milling machine can be used to process the loading jig 500, so as to obtain a frame 520 with a size that meets the requirements, so that the edges of the liquid crystal glass 20 and the glass cover plate 30 can be seamlessly attached to the frame 520, the edges of the liquid crystal glass 20 and the glass cover plate 30 are sealed, and it is difficult for glue to overflow through the edges of the liquid crystal glass 20 and the glass cover plate 30.

[0052] Since the edges of the liquid crystal glass 20 and the glass cover plate 30 are seamlessly attached to the frame 520, the present invention particularly opens a vent hole 512 at the bottom plate 510. When the liquid crystal glass 20 and the glass cover plate 30 are placed in the frame 520, the gas in the frame 520 is discharged through the vent hole 512. When the liquid crystal glass 20 and the glass cover plate 30 are taken out from the frame 520, air is still taken in through the vent hole 512, so that smooth removal is achieved.

[0053] After the liquid crystal glass 20 and the glass cover plate 30 are placed in the frame 520, due to good sealing, the glue will not overflow from the edge, and the pressing plate 420 applies pressure to the liquid crystal glass 20 and the glass cover plate 30 for a preset time, so that the glue 40 can flow fully between the liquid crystal glass 20 and the glass cover plate 30, ensuring that the thickness of the glue between the liquid crystal glass 20 and the glass cover plate 30 is uniform, thereby improving the quality of the product. The pressing plate 420 has a flat plate surface, and there is no need to exhaust air to the outside during the pressing process. Under the pressure of the pressing plate 420, the glue flows freely between the liquid crystal glass 20 and the glass cover plate 30 to obtain a uniform thickness.

[0054] In the present invention, the pressing device 400 further includes a pressing guide plate 430 , which is slidably disposed on the support frame 200 ; the pressing plate 420 is disposed on the pressing guide plate 430 via an elastic member 440 .

[0055] By arranging the elastic member 440 between the pressing plate 420 and the pressing guide plate 430, the pressing plate 420 can be in contact with the liquid crystal glass 20 and the glass cover plate 30 in a gentle manner, thereby preventing the liquid crystal glass 20 and the glass cover plate 30 from being broken due to sudden hard contact. In this embodiment, the spring member 440 is a cylindrical spring structure.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
