[0023] LED aluminum substrates are generally installed in the LED lamp holder. Baking the LED aluminum substrates is to eliminate the internal stress generated during the production of the sheet material, improve the dimensional stability of the material, and at the same time, remove the moisture absorbed by the sheet material during storage, increase the reliability of the material, so that the aluminum substrate can work more stably when used in LED lamps.

[0024] The feeding mechanism includes fixed frames 5 symmetrically fixed at the four corners of the baking oven 1, and the side walls of the four fixed frames 5 are rotatably connected to transmission wheels 6 through rotating shafts. The four transmission wheels 6 are connected for transmission through two vertically arranged transmission belts 7. The transmission belts 7 are wound around the side walls of the baking oven 1, and the outer side walls of the transmission belts 7 are fixedly connected to support racks 8 arranged at equal intervals. The support racks 8 are provided with grooves for placing the LED aluminum substrates. The two ends of the LED aluminum substrates can be directly placed flat on the two support racks 8, which is stable, does not require additional fixing mechanisms, and reduces the contact area. A double-axis driving mechanism is fixedly connected to the rear side of the upper end of the baking oven 1, and the two ends of the double-axis driving mechanism are respectively fixed to the two transmission wheels 6 located above. Fixed connection, when the dual-axis driving mechanism is working, it drives the two transmission wheels 6 above to rotate in the opposite direction. At this time, the two transmission belts 7 are synchronously transmitted in opposite directions, driving the support plate rack 8 to move. At this time, the LED aluminum substrate is placed on the two symmetrical support plate racks 8 from the top of the baking oven 1 for transportation. The operation is repeated. When the LED aluminum substrate moves to the bottom of the baking oven 1, the two support plate racks 8 swing to the outside of the transmission belt 7. At this time, the LED aluminum substrate is automatically dropped. The structural design is ingenious, making the loading and unloading of the LED aluminum substrate more convenient, and can ensure that both sides of the LED aluminum substrate can be baked at the same time. If conditions permit, a mechanical arm can be added to discharge the LED aluminum substrate to prevent scalding of the staff.

[0025] like Figure 1 and Figure 3As shown: the double-axis driving mechanism includes a casing 9 fixed to the rear side of the upper end of the baking oven 1, one end of the casing 9 is fixedly connected to a driving motor 10, and the main shaft end of the driving motor 10 passes through the casing 9 and is fixedly connected to a rotating rod 11, and two first bevel gears 12 arranged in opposite directions are fixedly connected to the rotating rod 11, and the front side wall of the casing 9 is inserted and rotatably connected to two symmetrically arranged rotating shafts 13, and one end of the two rotating shafts 13 is fixedly connected to a second bevel gear 14 meshing with the first bevel gear 12, and one end of the two rotating shafts 13 is respectively fixedly connected to the two transmission wheels 6, and the driving motor 10 is started to work, driving the rotating rod 11 to rotate, and since the two first bevel gears 12 are respectively meshed with the two second bevel gears 14, the two rotating shafts 13 are driven to rotate in the opposite directions at the same time, thereby driving the two transmission belts 7 to transmit in the opposite direction.

[0026] like Figure 3 As shown, two through holes are formed on the front side wall of the housing 9, and both through holes are rotatably connected to the two rotating shafts 13 through bearings to facilitate the rotation of the rotating shafts 13.

[0027] like Figure 1 and Figure 4 As shown: the hot air baking mechanism includes a heating box 15 fixed on the front side wall of the baking box 1, a blower 16 is connected to the side of the heating box 15 away from the baking box 1, an electric heating tube 17 is fixedly connected to the heating box 15, and the side wall of the heating box 15 is evenly provided with an air inlet pipe 18 connected to the baking box 1. The electric heating tube 17 is energized for heating, and at the same time, the blower 16 is started to work, so that hot air is blown into the baking box 1 through the air inlet pipe 18, so that the LED aluminum substrate entering the baking box 1 can be baked.

[0028] like Figure 1 As shown: the transmission belt 7 and the support frame 8 are fixedly connected by bolts in a detachable manner and can be disassembled for maintenance.

[0029] like Figure 1 As shown: a receiving box 3 is provided below the baking oven 1 to hold the fallen LED aluminum substrates.

[0030] like Figure 1 As shown: a control panel 4 is fixedly connected to the front side of the baking oven 1, and the control panel 4 is electrically connected to one end of the feeding mechanism and the hot air baking mechanism respectively, and an external power supply is connected through a plug wire, which is convenient to operate. It is a prior art, and a battery can also be installed to provide power output.

[0031] Working principle: When using the device to bake the LED aluminum substrate, first, the electric heating tube 17 is powered on for heating, and at the same time, the blower 16 is started to blow hot air into the baking oven 1 through the air inlet pipe 18, so that the LED aluminum substrate entering the baking oven 1 can be baked;

[0032] Then, the driving motor 10 is started to drive the rotating rod 11 to rotate. Since the two first bevel gears 12 are respectively engaged with the two second bevel gears 14, the two rotating shafts 13 are driven to rotate in the opposite direction at the same time, and then the two transmission wheels 6 on the top are driven to rotate in the opposite direction. At this time, the two transmission belts 7 are synchronously transmitted in opposite directions, driving the support frame 8 to move. At this time, the LED aluminum substrate is placed flat on the two symmetrical support frames 8 from the top of the baking oven 1 for downward transportation. The operation is repeated. When the LED aluminum substrate moves to the bottom of the baking oven 1, the two support frames 8 swing to the outside of the transmission belt 7. At this time, the LED aluminum substrate is automatically dropped. At the same time, the LED aluminum substrates on the support frames 8 are spaced apart from each other, thereby ensuring that both sides can be exposed to hot air for baking. The structural design is ingenious, which makes the loading and unloading of the LED aluminum substrate more convenient, improves the processing efficiency, and can ensure that both sides of the LED aluminum substrate are baked at the same time.
