[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0034] like Figure 1-Figure 4 As shown, the present embodiment provides a screen processing turnover pallet, comprising a pallet body 1, a plurality of first air holes 11 are arranged on the bottom wall of the pallet body 1, and a plurality of second air holes 12 are evenly spaced circumferentially arranged on the side wall of the pallet body 1, so that when the screen is being baked or degassed, the screen is placed flat in the pallet body and multiple pallets are stacked. At this time, except for the notch of the topmost pallet body which is open, the upper ends of the remaining pallet bodies are all covered, and hot air can flow from bottom to top between the multiple pallet bodies through the first air holes, and for a single pallet body, gas exchange can also be carried out inside and outside its groove through the second air holes, so that the degassed and drying effects are good, and the multiple layers of pallet bodies can still maintain a good drying effect when they are stacked (when multiple pallet bodies are superimposed on each other, the second air holes on each pallet body can still maintain air permeability inside and outside).

[0035] In order to remove the bubbles inside the screen during processing, degassing is required. In addition to pumping negative pressure, heating is also required to accelerate the overflow of bubbles. Therefore, in this embodiment, the first air hole and the second air hole are respectively provided on the groove bottom and side wall of the tray body, which is also conducive to the flow of gas to improve the tray effect.

[0036] The material of the tray body in this embodiment is heat-resistant plastic (such as nylon plastic or polyphenylene sulfide plastic, of course not limited to, as long as it can withstand the baking temperature when the screen is baked).

[0037] like Figure 3 and Figure 4 As shown, the notch of the tray body 1 in the above technical solution is expanded outward in a stepped shape to form a socket at the notch of the tray body 1, and a stepped plug-in end is formed at the lower end of the tray body 1, so that when multiple tray bodies are stacked, two adjacent tray bodies can be plugged into and stacked on each other, which ensures good stability during stacking and will not crush the screen (in this embodiment, when two tray bodies are stacked, the plug-in end at the lower end of the upper tray body can be exactly embedded in the socket).

[0038] like Figure 5 As shown, the above technical solution also includes a mesh anti-skid pad 2, which is laid flat on the bottom wall of the groove of the tray body 1. By setting the mesh anti-skid pad, the screen is not easy to slide in the tray body, and the bottom wall of the groove of the tray body is kept with good air permeability. The anti-skid pad can be made of silicone or silicone rubber (of course not limited to, as long as it can withstand the baking temperature when the screen is baked).

[0039] like Figure 5 and Figure 6As shown, the edge and the middle of the bottom wall of the groove of the tray body 1 in the above technical solution are provided with a plurality of mortise holes 13, and the lower end of the anti-slip pad 2 is convexly provided with a plurality of mortise and tenon parts 21, and the plurality of mortise and tenon parts 21 correspond to the plurality of mortise holes 13 one by one, and each of the mortise and tenon parts 21 is inserted in the corresponding mortise hole 13, so as to prevent the anti-slip pad from loosening on the bottom wall of the groove of the tray body (the mortise hole can be a trumpet-shaped hole with the larger end of the opening facing upward, and the lower end of the mortise and tenon part is turned outward and conical, so that the mortise and tenon part can be inserted into the mortise hole for convenience, and can be buckled after insertion without being easily loosened).

[0040] like Figure 7 As shown, the size and shape of the anti-slip pad in this embodiment are consistent with the inner bottom wall of the tray body, except that there are gaps at its four corners to expose the adsorption area 14 on the inner bottom wall of the tray body, and the multiple mortise and tenon parts at its lower end correspond one to one (the mesh on the anti-slip pad corresponds one to one and is aligned with the first air holes on the inner bottom wall of the tray body), wherein, Figure 7 The middle hexagonal holes represent the mesh of the anti-slip mat.

[0041] The tray body 1 described in the above technical solution is rectangular and has a simple structure. When placing a screen, its internal space utilization rate is better (the multiple mortise holes located at the edge are evenly distributed along the circumferential direction on the groove bottom wall of the tray body, and the mortise holes in the middle of the groove bottom wall of the tray body are distributed in multiple rows and columns, and the first air vent is not arranged between two adjacent mortise holes in the same row and column, and the hole density here is low, so the structural strength is correspondingly high).

[0042] like Figure 1 and Figure 2 As shown, smooth adsorption areas 14 are formed at the four corners of the bottom wall of the groove of the pallet body 1 in the above technical solution, and the remaining part of the bottom wall of the groove of the pallet body 1 is densely covered with a plurality of the first air holes 11, which is beneficial for transferring the pallet by adsorbing the four adsorption areas by four suction cups during automated processing of the pallet (notches are provided at the four corners of the anti-slip pad to expose the four adsorption areas 14 for easy adsorption by the suction cups).

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the two wide sides of the notch of the tray body 1 in the above technical solution are both turned outward to form a handle portion 15, so that the tray body is easy to be held manually with both hands, and a visual marker 16 is provided at one end of any one of the handles 15, so that during the automated processing of the screen, the visual positioning equipment can use the visual marker as an identification target and locate its position and orientation (the visual marker 16 in this embodiment can be a bevel treatment on one end of a handle, and the bevel formed at this time is the visual marker 16).

[0044] The opening rate of the first air holes 11 on the bottom wall of the groove of the tray body 1 described in the above technical solution is more than 90% (of course, it should not be higher than 98%. At this time, the bottom wall of the groove of the entire tray body is equivalent to a hard mesh structure except for the four adsorption areas. In this embodiment, the opening rate is the ratio of the total area of ​​the first air holes to the area of ​​the bottom wall of the tray body), so that the ventilation performance of the bottom wall of the groove of the tray body is excellent.

[0045] In the above technical scheme, the first air hole 11 is a round hole, a square hole, a waisted hole or a hexagonal hole (the mesh of the anti-slip pad in this embodiment can be consistent with the shape and size of the first air hole and be in an aligned state); the groove depth of the tray body 1 is 1-10cm (specifically, the groove depth of the tray body can be 1cm, 1.5cm, 2cm, 2.5cm, 3cm, 3.5cm, 4cm, 4.5cm, 5cm, 5.5cm, 6cm, 6.5cm, 7cm, 7.5cm, 8cm, 8.5cm, 9cm, 9.5cm or 10cm), which has a simple structure, and the groove depth of the tray body is set to 1-3cm to thin the tray body, so that more tray bodies can be stacked at a limited height.

[0046] like Figure 3-Figure 5 and Figure 8 As shown, the notch of the tray body in this embodiment is expanded outward in a step-shaped manner so that its internal space forms a groove lower part 18 and a groove upper part 17. In addition, the outer side of the tray body also forms an annular inverted step shape at the expanded opening. At this time, the shape and size of the bottom wall of the lower end of the tray body just match the notch of the tray body so that they can be plugged into each other when stacked (so that the lower end of the tray body constitutes a plug-in end, and the upper part of the groove constitutes a socket). In addition, the depth of the upper part of the groove is smaller than the depth of the lower part of the groove, and the second air hole can be a vertically arranged strip hole, the lower end of which is flush with the inner bottom wall of the tray body, and the upper end of which can be flush with the junction of the expanded opening of the tray body. Even if multiple tray bodies are plugged into each other for stacking, the second air hole can still maintain the inside and outside of the tray body through (specifically, the length of the second air hole is greater than the depth of the upper part of the groove and will not be completely covered and blocked), wherein, Figure 8 The dashed arrow in the middle indicates the direction of air flow.

[0047] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
