DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 , the present invention provides a technical solution:

[0031] Embodiment 1:

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

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

[0034] The lifting slots 8 on both sides are also provided with pad flaps 10 in a lifting manner. The pad flaps 10 transfer the isolation pads 9 from the pad conveying mechanism to the heat shielding plate 2, so that the isolation pads 9 are used to separate the stacked layers of heat shielding plates 2 to form isolation gaps 11;

[0035] An anti-rust spraying mechanism is also provided in the matching seat 5. A plurality of linearly arranged spray holes 12 are evenly spaced on the stacking column 1. The spray holes 12 are connected to the anti-rust spraying mechanism. The spray holes 12 are provided at the isolation gaps 11 formed by the stacked heat shielding plates 2. When the heat shielding plates 2 are stacked to a preset height, the anti-rust spraying mechanism sprays atomized spray into the isolation gaps 11 of each layer through the spray holes 12.

[0036] In this embodiment, the heat shield 2 is an annular structure with a through hole 3 in the middle, which provides a prerequisite for interlaced stacking using the through hole 3 in the middle. The diameter of the stacking column 1 is smaller than the diameter of the through hole 3 of the heat shield 2, so that it can smoothly fall on the stacking column 1. The stacking column 1 has an end 4 with a gradually increasing diameter from top to bottom, which is more conducive to the heat shield 2 falling in. In order to prevent the heat shield 2 from falling and causing collision and compression damage to the heat shield 2 below, this embodiment can also place isolation pads 9 between adjacent heat shields 2, so as to provide buffer protection for each stacked layer, and the isolation pads 9 are transmitted through the pads. The mechanism is transported upward from the bottom of the mechanism cabin 6, and pauses when it reaches the specified position. At this time, the isolation pad 9 is removed from the pad conveying mechanism by the pad flap 10 set in the lifting slot 8 and contacts the heat shield 2 by descending, so as to be glued to the heat shield 2. Since both sides of the isolation pad 9 are coated with 3M traceless glue, both sides are adhesive. Therefore, in order to ensure that the isolation pad 9 can be smoothly transferred between multiple structures, the contact area between the pad conveying mechanism and the isolation pad 9 is smaller than the pad flap 10, and the contact area of ​​the isolation pad 9 on the pad flap 10 is smaller than The heat shield 2 is provided in this way, so that the isolation pad 9 has a greater adhesiveness on the object with a large contact area, thereby ensuring that the isolation pad 9 can be smoothly transferred to the surface of the heat shield 2. At the same time, since the heat shield 2 produced by our company has a special-shaped cross-section, and a hollow isolation gap 11 is formed by the isolation of the isolation pad 9, and the thickness of the heat shield 2 and the isolation pad 9 can be determined, a spray hole 12 is opened at the isolation gap 11 of the stacking column 1, and the spray hole 12 is connected to the anti-rust spray can 28, so that the anti-rust spray is sprayed after the stacking is completed. This operation can significantly reduce the heat shield 2. Surface corrosion during subsequent transportation is prevented, thereby further improving the quality of the workpiece. The conduction between the anti-rust spray can 28 and the spray hole 12 is achieved by the opening and closing of the solenoid valve 7. The solenoid valve 7 is controlled by the main control MCU built into the stacking column 1. The main control MCU is also electrically connected to the distance sensor 31. By setting, when the distance sensor 31 is blocked for more than 2S, it can be determined that the heat shield 2 has been stacked to this height. At this time, the anti-rust spray can 28 and the spray hole 12 are connected through the solenoid valve 7 to release the anti-rust spray into the isolation gap 11. The above device can complete the efficient stacking of the heat shield 2 at a low cost.

[0037] Embodiment 2:

[0038] A pair of stacking columns 1 are provided, and the pair of stacking columns 1 are fixedly installed on a rotating base 13. A rotating motor 14 is installed at the bottom of the rotating base 13. The rotating motor 14 rotates to drive the stacking columns 1 on both sides to be alternately arranged under the heat shield plate conveyor line 15. The heat shield plate 2 is transported through the heat shield plate conveyor line 15 and falls through the inclined plate 16, and is finally stacked on the stacking columns 1.

[0039] In this embodiment, a pair of stacking columns 1 are provided. When the stacking of the stacking columns 1 on one side is completed, the stacking columns 1 on the other side can be quickly moved to the bottom of the heat shield conveyor line 15 through the rotation of the rotating motor 14, thereby performing continuous stacking operations.

[0040] Embodiment three:

[0042] Both sides of the isolation pad 9 are coated with 3M traceless glue. The isolation pad 9 is glued to the bottom conveyor belt 18 during the unwinding process and is transported upward by the movement of the conveyor belt 18.

[0043] In this embodiment, the specific structure of the pad conveying mechanism is further disclosed, in which the two sides of the isolation pad 9 are glued and fixed by two conveyor belts 18, and transported upward with the rotation of the conveying roller 17 until it enters one side of the lifting groove 8, wherein the conveying motor is fixedly installed in the mechanism cabin 6, which is electrically connected to the main control MCU, and performs intermittent work under the control of the main control MCU.

The axis of the winding turntable 24 is also fixedly connected to the winding motor, and the lifting block is driven to perform lifting movement through the rotation of the winding motor. The traction spring 22 pulls the lifting block 19 upward without external force.

[0046] The pad flap 10 includes a flipping portion 25 and a prying portion 26. A torsion spring is arranged in the pad flap 10. The torsion spring is used to drive the flipping surface of the flipping portion 25 to be perpendicular to the lifting slide bar 20 without external force. A prying block 27 is also fixedly installed in the mechanism cabin 6. The prying block 27 is used to cooperate with the prying portion 26 to prompt the prying portion 26 to drive the flipping portion 25 to flip upward 90° so that the flipping portion 25 is accommodated in the lifting groove 8. Through the flipping of the flipping portion 25, the isolation pad 9 glued to the conveyor belt 18 is transferred and glued to the flipping portion 25, and descends together with the pad flap 10 until it contacts the heat shield plate 2 and then adheres to the heat shield plate 2, thereby completing the transfer of the isolation pad 9.

[0047] In this embodiment, the specific structure of the pad flap 10 and the related mechanism associated therewith is further disclosed. The pad flap 10 includes a flipping portion 25 and a prying portion 26. The pad flap 10 is fixed-axis rotatably mounted on the lifting block 19.

In combination with Example 3, the flipping part 25 is arranged between the conveyor belts 18 on both sides, so that the flipping of the flipping part 25 will not affect the movement of the pad conveying mechanism.
