[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following description, with reference to the accompanying drawings, describes a hot air drying apparatus used in the manufacturing process of an LED display panel according to an embodiment of the present invention.

[0017] like Figures 1-5 As shown, a hot air drying device used in the manufacturing process of an LED display panel includes a dryer 1 and a heating mechanism 2. The heating mechanism 2 includes a bracket 21, a heat-conducting pipe 23, a protective cover 24, a heating column 25, a connector 26, and an adjustment component 27. The bracket 21 is fixed inside the dryer 1, and positioning grooves 22 are respectively opened on the bracket 21. The side walls of the heat-conducting pipe 23 are respectively fixed on the inner side walls of the corresponding positioning grooves 22. The protective cover 24 is fixedly connected to both ends of the corresponding heat-conducting pipe 23. The two ends of the heating column 25 pass through the corresponding heat-conducting pipe 23 and are fixedly connected to the corresponding connector 26. The adjustment component 27 is respectively provided inside the dryer 1.

[0018] The dryer 1 includes a body 11 and a first drive unit 13. Hot air holes 12 are respectively opened on the side wall of the body 11. The output end of the first drive unit 13 passes through the corresponding hot air holes 12 and is fixedly connected to the inner side wall of the hot air holes 12.

[0019] It should be noted that the first driving component 13 described in this embodiment is a hot air blower, and the first driving component 13 is fixed on the outer wall of the body 11.

[0020] It should be noted that the filling material between the heating column 25 and the heat conduction pipe 23 is fused magnesium sand, which serves as insulation and heat conduction.

[0021] The adjustment assembly 27 includes a second drive member 2701, a top plate 2702, an adjustment column 2703, a connecting column 2705, a rotating rod 2706, a fixed column 2707, a blade 2708, and a support plate 2709. The second drive member 2701 is fixed to the inner wall of the body 11. The bottom wall of the top plate 2702 is fixedly connected to the output end of the second drive member 2701. One end of the adjustment column 2703 is fixedly connected to the upper wall of the top plate 2702. The connecting column 2705 passes through the two side walls of the corresponding adjustment column 2703. The corresponding adjusting column 2703 is rotatably connected, one end of the rotating rod 2706 is rotatably connected to the corresponding connecting column 2705, one end of the fixing column 2707 is fixedly connected to the other end of the corresponding rotating rod 2706, both ends of the blade 2708 are fixedly connected to the other end of the corresponding fixing column 2707, the side wall of the support plate 2709 is fixed on the inner wall of the body 11, and the fixing column 2707 passes through the two side walls of the corresponding support plate 2709 and is rotatably connected to the corresponding support plate 2709.

[0022] The adjusting column 2703 is provided with a rotating hole 2704, and the support plate 2709 is provided with a through hole 2710.

[0023] It should be noted that the second driving component 2701 described in this embodiment is an electric push rod.

[0024] Specifically, when drying the LED display panel, it is only necessary to start the first drive unit 13 and the second drive unit 2701. After the first drive unit 13 is started, hot air is blown out and enters the machine body 11 through the hot air hole 12. In addition, the heating column 25 is powered by the connector 26. The electrical energy is converted into heat energy under the action of the heating column 25. The heat is conducted to the heat pipe 23, thereby drying the internal LED display panel.

[0025] Simultaneously, the second driving component 2701 pulls down the top plate 2702, thereby causing the adjusting column 2703 to descend. The adjusting column 2703 further drives the end of the rotating rod 2706 rotatably connected to the connecting column 2705 to descend through the connecting column 2705, thereby causing the other end of the rotating rod 2706 to rotate around the fixed column 2707, which in turn drives the fixed column 2707 to rotate. The fixed column 2707 then drives the blade 2708 to rotate, thereby adjusting the direction of the hot air blown out of the hot air hole 12.

[0026] In one embodiment of this utility model, such as Figure 1 As shown, a heat insulation plate 3 is fixedly connected to the inner wall of the body 11.

[0027] It is understandable that by setting up the heat insulation plate 3, the second drive component 2701 can be effectively protected and prevented from being damaged by high temperature.

[0028] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, foot pads 4 are fixedly connected to the bottom wall of the body 11.

[0029] Understandably, the stability of the body 11 can be enhanced by setting foot pads 4.

[0030] Working principle: When using this utility model to dry the LED display panel, the first driving component 13 and the second driving component 2701 are activated. The first driving component 13 blows out hot air and enters the machine body 11 through the hot air hole 12. In addition, the heating column 25 is powered by the connector 26. The electrical energy is converted into heat energy under the action of the heating column 25. The heat is conducted to the heat pipe 23, thereby drying the internal LED display panel.

[0031] Simultaneously, the second driving component 2701 pulls down the top plate 2702, thereby causing the adjusting column 2703 to descend. The adjusting column 2703 further drives the end of the rotating rod 2706 rotatably connected to the connecting column 2705 to descend through the connecting column 2705, thereby causing the other end of the rotating rod 2706 to rotate around the fixed column 2707, which in turn drives the fixed column 2707 to rotate. The fixed column 2707 then drives the blade 2708 to rotate, thereby adjusting the direction of the hot air blown out of the hot air hole 12.

[0032] In summary, by using an independent connector 26 to supply power and control the heating columns 25 inside the device, each heating column 25 can work and be tested independently. When the device malfunctions, the fault can be quickly identified by testing each heating column 25 one by one without disassembling the device, thus improving the efficiency of fault diagnosis.
