DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-8 , the present application provides a technical solution:

[0031] Embodiment one:

[0032] A heat shield plate stacking mechanism, comprising a stacking column 1, the stacking column 1 is used for the through hole 3 on the heat shield plate 2 to pass through, a plurality of heat shield plates 2 are placed in a stacked manner on the stacking column 1, the stacking column 1 is provided with an end 4 with a diameter gradually increasing from top to bottom at the upper end, the stacking column 1 is fixedly installed on the matching seat 5 away from the end 4, the stacking column 1 is provided with a hollow mechanism cabin 6, and the stacking column 1 is provided with lifting grooves 8 penetrating in and out symmetrically on both sides;

[0033] The mechanism cabin 6 is provided with a pad conveying mechanism corresponding to the lifting grooves 8 on both sides, and the pad conveying mechanism conveys the isolation pad 9 upward from the bottom;

[0034] The lifting grooves 8 on both sides are further provided with a pad turning plate 10 in a lifting manner, the pad turning plate 10 transfers the isolation pad 9 from the pad conveying mechanism to the heat shield plate 2, so that the isolation gap 11 is formed between the stacked heat shield plates 2 through the isolation pad 9;

[0035] The anti-rust spraying mechanism is further arranged in the fitting seat 5, a plurality of linearly arranged spray holes 12 are arranged on the stacking column 1 at equal intervals, the spray holes 12 are communicated with the anti-rust spraying mechanism, and the spray holes 12 are arranged at the isolation gaps 11 formed by the heat shielding plates 2 in the stacked state. After the heat shielding plates 2 are stacked to the preset height, the anti-rust spraying mechanism sprays mist to the isolation gaps 11 of each layer through the spray holes 12.

[0036] In this embodiment, the heat shielding plate 2 is an annular structure member with a through hole 3 in the middle, thereby providing a prerequisite for the insertion type stacking by using the through hole 3 in the middle. The diameter of the stacking column 1 is smaller than that of the through hole 3 of the heat shielding plate 2, thereby enabling the heat shielding plate 2 to smoothly fall on the stacking column 1. The stacking column 1 has an end 4 with a gradually increasing diameter from top to bottom, thereby being more conducive to the falling of the heat shielding plate 2. In order to prevent the falling of the heat shielding plate 2 from causing collision and extrusion damage to the heat shielding plate 2 below, the embodiment further enables the placement of isolation pads 9 between adjacent heat shielding plates 2, thereby buffering and protecting each layer of the stacked heat shielding plates 2. The isolation pads 9 are conveyed upward from the lower part of the mechanism cabin 6 by a pad conveying mechanism, and are paused when reaching the specified position. At this time, the isolation pad 9 is taken off from the pad conveying mechanism by the pad turning plate 10 arranged in the lifting groove 8, and is lowered to contact the heat shielding plate 2, thereby being glued to the heat shielding plate 2. Since the isolation pad 9 is coated with 3M traceless glue on both sides, both sides of the isolation pad 9 have adhesive properties. Therefore, in order to ensure that the isolation pad 9 can be smoothly transferred and glued between multiple structures, the contact area of the pad conveying mechanism and the isolation pad 9 is smaller than that of the pad turning plate 10, and the contact area of the isolation pad 9 on the pad turning plate 10 is smaller than that of the heat shielding plate 2. Through this arrangement, the isolation pad 9 has greater adhesive properties on objects with a larger contact area, thereby ensuring that the isolation pad 9 can be smoothly transferred to the surface of the heat shielding plate 2. Since the heat shielding plate 2 produced by the company has a special cross section and forms a hollow isolation gap 11 through the isolation of the isolation pad 9, and the thickness of the heat shielding plate 2 and the isolation pad 9 can be determined, the spray hole 12 is arranged on the stacking column 1 at the isolation gap 11. The spray hole 12 is communicated with the anti-rust spray tank 28, thereby enabling the anti-rust spraying after the stacking is completed. This operation can significantly reduce the surface corrosion of the heat shielding plate 2 during the subsequent transportation process, thereby further improving the quality of the workpiece. The communication between the anti-rust spray tank 28 and the spray hole 12 is realized by the opening and closing of the electromagnetic valve 7. The electromagnetic valve 7 is controlled by the main control MCU built in the stacking column 1. The main control MCU is further electrically connected with the distance measuring sensor 31. When the distance measuring sensor 31 is blocked for more than 2S, it is determined that the heat shielding plate 2 has been stacked to this height. At this time, the electromagnetic valve 7 is turned on to connect the anti-rust spray tank 28 and the spray hole 12, thereby releasing the anti-rust spray into the isolation gap 11. Through the above device, the efficient stacking of the heat shielding plate 2 can be completed at a low cost.

The heat shield plate 2 is conveyed through the heat shield plate conveying line 15 and falls through the inclined plate 16. Finally, the heat shield plate 2 is stacked on the stacking column 1.

[0039] In this embodiment, the stacking column 1 is provided with a pair. When the stacking of the stacking column 1 on one side is completed, the stacking column 1 on the other side can be quickly moved to the bottom of the heat shield plate conveying line 15 through the rotation of the rotating motor 14, so that continuous stacking operation is realized.
