DETAILED DESCRIPTION

[0017] The following are examples and the attached Figure 1 , the technical solution of the present invention is further specifically described.

[0018] An oven structure for LED production includes a box body 1, wherein an inlet and outlet 2 is arranged on the side wall of the box body 1, and a switch door is arranged at the inlet and outlet 2:

[0019] The bottom of the box body 1 is open, wherein cover plates 3 are hinged on both sides of the bottom of the box body 1, and the two sets of cover plates 3 seal the bottom opening of the box body 1, and a base 4 is also provided below the box body 1 to abut against the bottom of the two sets of cover plates 3, wherein the base 4 is driven by a hydraulic rod;

[0020] A jacket 5 is provided on the outside of the box body 1, wherein a U-shaped recovery pipe 6 connected to the jacket 5 is provided on the top of the box body 1, and an exhaust pipe 7 is provided on the recovery pipe 6, and a plurality of groups of orifice plates 8 are arranged in parallel up and down in the box body 1, wherein a rotating shaft 9 is longitudinally provided in the middle of the bottom of the orifice plate 8, and a level 10 is provided at the bottom of the orifice plate 8 on the same side as the inlet and outlet 2, and a limiting mechanism 11 away from the inlet and outlet 2 is provided in the box body 1 on one side of the orifice plate 8, wherein the limiting mechanism 11 includes a rotating shaft 112 driven by a motor 111, and the rotating shaft 112 is provided with clamping plates 113 located on both sides of the upper and lower sides of the orifice plate 8.

[0021] like Figure 1 As shown, the exhaust pipe 7 is provided with a solenoid valve I12 , and the recovery pipe 6 is provided with a solenoid valve II13 , wherein the solenoid valve II13 is provided on the recovery pipe 6 between the exhaust pipe 7 and the jacket 5 .

[0022] In this embodiment, an air outlet pipe is arranged on the jacket 5 , wherein a temperature sensor and a humidity sensor are also arranged inside the jacket 5 .

[0023] like Figure 1 As shown, a boss 14 for fixing the rotating shaft 112 is arranged on the inner wall of the box body 1, wherein a rolling bearing which is sleeved on the rotating shaft 112 is arranged on the boss 14.

[0024] like Figure 1 As shown, a plurality of groups of air inlet pipes 15 parallel to the rotating shaft 9 are arranged at the bottom of the box body 1, wherein air outlets are evenly arranged at the tops of the air inlet pipes 15.

[0025] In this embodiment, a rubber sealing layer is bonded to the joint between the cover plate 3 and the bottom of the side wall of the box body 1 .

[0026] The method of use of the present invention: Figure 1 As shown, one end of the orifice plate 8 is supported by the rotating shaft 9, and the rotating shaft 112 clamps and fixes the other end of the orifice plate 8 through the upper and lower clamping plates 113 to prevent the orifice plate 8 from rotating with the rotating shaft 9 as the center. After the product is placed on the orifice plate 8, the hot air flow is introduced into the box body 1 through the air inlet pipe 15, wherein the hot air flow passes through the aperture of the orifice plate 8 to dry the bottom end surface of the product and the top end surface of the product, and the hot air flow can also enter the jacket 5 through the recovery pipe 6 to heat it, thereby keeping the box body 1 warm to fully recover the heat in the hot air flow;

[0027] When it is necessary to clean the box 1, since the box 1 is suspended in the air, the hydraulic rod drives the base 4 to move downward. Under the premise of losing the support of the base 4, the cover 3 will rotate with its direct hinge with the box 1 as the center, and then the bottom of the box 1 will be opened. At this time, there is no dead angle at the bottom of the box 1, which makes it easy to clean the impurities at the bottom without silting. At the same time, the impurities cleaned on the inner wall of the box 1 are also easy to discharge. At the same time, the motor 111 drives the rotating shaft 112 to drive the clamping plate 113 to rotate 90 to 180 degrees, so that the clamping plate 113 is separated from the end of the orifice plate 8. At this time, the orifice plate 8 will rotate with the rotating shaft 9 as the center, so that the orifice plate 8 is tilted to facilitate the falling and cleaning of impurities on its top. After cleaning, the orifice plate 8 is rotated to make it horizontal, and its levelness is adjusted by the spirit level 10. Then the rotating shaft 112 drives the clamping plate 113 to clamp and fix the left end of the orifice plate 8 to make it horizontal.

[0028] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
