[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The utility model discloses a hot pressing device for producing a digital display screen, comprising a mounting frame 1, a pressing mechanism 2 and a moving mechanism 3.

[0035] The pressing mechanism 2 is arranged on the mounting frame 1. The pressing mechanism 2 comprises a pressing cylinder 21, a pressing plate 22, a heating element 23 and a pressing die 24. The pressing cylinder 21 is arranged on the mounting frame 1. The pressing plate 22 is connected to the telescopic rod of the pressing cylinder 21. The heating element 23 is arranged on the pressing plate 22. The pressing die 24 is arranged on the heating element 23.

[0036] The moving mechanism 3 is arranged on the mounting frame 1 and is located below the pressing mechanism 2. The moving mechanism 3 includes a moving fixture 31 for placing the light board and the bracket, and the moving fixture 31 can drive the light board and the bracket to move directly below the pressing mechanism 2 or not directly below the pressing mechanism 2.

[0037] In a specific application, the mobile jig 31 is moved to a position not directly below the pressing mechanism 2, and the lamp board and the bracket to be hot pressed together are placed on the mobile jig 31. After placement, the mobile jig 31 is moved to directly below the pressing mechanism 2 and the pressing mechanism 2 is started. The pressing cylinder 21 drives the lower pressing plate 22 to move downward, thereby driving the heating element 23 and the lower pressing die 24 to move downward until the lower pressing die 24 abuts against the bracket. The heat generated by the heating element 23 when it is energized is transferred to the bracket through the lower pressing die 24, so that the bracket and the lamp board are hot pressed together.

[0038] Through the above technical solution, the movable fixture 31 can move back and forth directly below the pressing mechanism 2 and not directly below the pressing mechanism 2, which not only facilitates the removal and placement of the light board and the bracket, but also eliminates the safety hazard of burns caused by accidentally touching the pressing mechanism 2.

[0039] In order to ensure that the mobile jig 31 moves accurately to the bottom of the pressing mechanism 2, in some preferred embodiments, the mobile mechanism 3 further includes a positioning block 32, which is arranged on the mounting frame 1 and is located on the moving path of the mobile jig 31. When the mobile jig 31 drives the light board and the bracket to move to the bottom of the pressing mechanism 2, the mobile jig 31 abuts against the positioning block 32. In a specific application, when the mobile jig 31 is pushed to move to the bottom of the pressing mechanism 2, when the mobile jig 31 abuts against the positioning block 32, the mobile jig 31 cannot be pushed further. At this time, it can be determined that the mobile jig 31 is located directly below the pressing mechanism 2.

[0040] Refer to Figure 5In some preferred embodiments, the mobile fixture 31 includes a mobile plate 311, a first positioning block 312, a second positioning block 313 and a supporting plate 314. The first positioning block 312 is arranged on the mobile plate 311, and the length direction of the first positioning block 312 is consistent with the length direction of the mobile plate 311; the second positioning block 313 is arranged on the mobile plate 311, and the length direction of the second positioning block 313 is consistent with the width direction of the mobile plate 311, and a placement position is formed between the mobile plate 311, the first positioning block 312 and the second positioning block 313; the supporting plate 314 is detachably arranged in the placement position, and a placement groove 3141 for placing the lamp board and the bracket is provided on the supporting plate 314. In a specific application, after placing the light board and the bracket in the placement groove 3141, the carrier plate 314 is placed on the movable plate 311, and the long side of the carrier plate 314 is fitted with the first positioning block 312, and the short side of the carrier plate 314 is fitted with the second positioning block 313, so that the carrier plate 314 is accurately located at the placement position, and then, the movable plate 311 is pushed so that the carrier plate 314 drives the light board and the bracket to move to the bottom of the pressing mechanism 2 for hot pressing. Specifically, the number of carrier plates 314 can be multiple. When one carrier plate 314 drives the light board and the bracket to move to the bottom of the pressing mechanism 2 for hot pressing, the light board and the bracket can be placed on another carrier plate 314. After the hot pressing of the light board and the bracket on one carrier plate 314 is completed, the movable plate 311 drives the carrier plate 314 to move to a position not directly below the pressing mechanism 2. It is only necessary to remove the carrier plate 314 and replace it with another carrier plate 314 on which the light board and the bracket have been placed. In this way, production efficiency can be improved.

[0041] In some preferred embodiments, the second positioning block 313 is provided with an elongated hole 3131, and the length direction of the elongated hole 3131 is consistent with the length direction of the movable plate 311. In specific applications, one end of a bolt passes through the elongated hole 3131 and is connected to the movable plate 311 to realize the installation of the second positioning block 313 on the movable plate 311, and the second positioning block 313 can be moved in the length direction of the movable plate 311 by loosening the bolt, so that the second positioning block 313 can position the bearing plates 314 of different lengths, thereby expanding the scope of application.

[0042] In some preferred embodiments, the mobile mechanism 3 further includes a guide rail 33, which is laid on the mounting frame 1, and the mobile fixture 31 is slidably arranged on the guide rail 33. In specific applications, the guide rail 33 can not only guide the mobile fixture 31, but also reduce the friction between the mobile fixture 31 and the mounting frame 1.

[0043] In some preferred embodiments, both ends of the guide rail 33 are provided with anti-slip blocks 34. In specific applications, the anti-slip blocks 34 can play a limiting role when the mobile fixture 31 moves, so as to prevent the mobile fixture 31 from escaping from the guide rail 33.

[0044] In some preferred embodiments, the mobile jig 31 is provided with an extension plate 315, and the extension plate 315 is provided with a handle 316. In specific applications, by providing the extension plate 315 on the mobile jig 31 and providing the handle 316 on the extension plate 315, it is not only convenient to push and pull the mobile jig 31, but also it is possible to prevent the heat from being transferred to the handle 316 during the hot pressing process.

[0045] In some preferred embodiments, the pressing mechanism 2 further includes a guide rod 25. The guide rod 25 is disposed on the mounting frame 1 and is parallel to the telescopic rod of the pressing cylinder 21; the pressing plate 22 is sleeved on the guide rod 25. In specific applications, the guide rod 25 guides the pressing plate 22 to ensure that the pressing die 24 is pressed accurately.

[0046] In some preferred embodiments, the hot pressing device for producing digital display screens further comprises a controller 4, which is arranged on the mounting frame 1 and electrically connected to the pressing mechanism 2. In specific applications, the controller 4 is not only used to control the raising and pressing of the pressing mechanism 2, but also to display the temperature of the heating element 23 in real time, so as to avoid the influence of the over-high temperature of the heating element 23 on the hot pressing of the bracket and the light board.

[0047] To sum up, the hot pressing device for producing digital display screens of the utility model sets a movable jig 31 below the pressing mechanism 2, so that the movable jig 31 can move back and forth between directly below the pressing mechanism 2 and not directly below the pressing mechanism 2, so that the light board and the bracket can be taken and placed when the movable jig 31 moves to not directly below the pressing mechanism 2, which not only facilitates the taking and placing of the light board and the bracket, but also eliminates the safety hazard of burns caused by accidentally touching the pressing mechanism 2.

[0048] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
