[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0026] It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components described in these embodiments do not limit the scope of this application.

[0027] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0030] The applicant's research found that the existing tray only includes the existing tray body formed by the manufacturing process, and the existing receiving slot is a groove structure set in the tray body. Typically, in order to facilitate the placement and gripping of OLED flexible display panels (hereinafter referred to as display panels), the existing receiving slot is larger than the display panel. Therefore, after the display panel is placed in the existing receiving slot, there will be a certain gap between the edge of the display panel and the wall of the existing receiving slot.

[0031] Furthermore, since the material of the existing tray body (e.g., ordinary plastic) has a low coefficient of friction, the friction between the display panel and the bottom of the existing receiving groove is small, which cannot effectively prevent the display panel from sliding in the existing receiving groove. Therefore, during the transfer process, the display panel will move in the existing receiving groove and hit the groove wall, causing damage to the corners of the display panel.

[0032] Meanwhile, when the display panel moves within the existing receiving slot, it rubs against the bottom of the slot, which can easily generate static electricity. The existing tray body cannot reliably discharge static electricity from the display panel, and the retention of static electricity can cause significant damage to the display panel.

[0033] In summary, in order to protect the display panel during transportation, it is necessary to prevent the display panel from moving relative to the tray, and at the same time, to discharge the static electricity remaining on the display panel.

[0034] In view of this, such as Figure 1 As shown, this application embodiment provides an anti-slip mat 1, including: a mat body 101, which includes a first surface 1011 and a second surface 1012 opposite to each other, the first surface 1011 being provided with anti-slip textures 1013 for contacting the surface of a product 2; and an electrostatic discharge layer 102 disposed on the second surface 1012 for connecting with a tray to guide the electrostatic discharge of the product discharged by the mat body 101 to the tray.

[0035] Exemplarily, the gasket body 101 and the static electricity leading-out layer 102 are made of materials with the function of conducting static electricity.

[0036] In order to prevent the relative sliding between the product 2 and the tray, the friction between the product 2 and the surface of the structure in contact with the product 2 needs to be increased. Since the weight of the product 2 cannot be changed, the friction coefficient of the surface in contact with the product 2 needs to be increased. For this purpose, the first surface 1011 of the gasket body 101 is used as the surface in contact with the product 2, and the anti-skid pattern 1013 is arranged on the first surface 1011 to reduce the smoothness of the first surface 1011 and increase the friction coefficient thereof.

[0037] Meanwhile, since the gasket body 101 and the static electricity leading-out layer 102 both have the function of conducting static electricity, when the product 2 is in contact with the gasket body 101, if the product 2 has static electricity remaining thereon, the gasket body 101 and the static electricity leading-out layer 102 are at a lower potential than the product 2 with the static electricity remaining thereon. Therefore, the static electricity of the product can be led out through the gasket body 101 and then led to the tray through the static electricity leading-out layer 102.

[0038] Exemplarily, the tray can be provided with a grounding wire to lead the static electricity on the tray to the ground, so that the gasket body 101, the static electricity leading-out layer 102 and the tray are kept at a low potential and have the ability to continuously and reliably dissipate the static electricity of the product.

[0039] The anti-skid gasket 1 provided by the embodiment can increase the friction coefficient of the first surface 1011 of the gasket body 101 by arranging the anti-skid pattern 1013 on the first surface 1011, increase the friction between the first surface 1011 and the product 2 when the first surface 1011 is in contact with the product 2, and prevent the relative sliding between the product 2 and the tray during the transfer of the product 2. Meanwhile, when the product 2 has static electricity remaining thereon, the static electricity can be led out from the product 2 through the gasket body 101 and the static electricity leading-out layer 102 arranged on the second surface 1012 of the gasket body 101, and the static electricity remaining on the product 2 can be effectively prevented from damaging the product 2.

[0040] As shown in FIGS. Figure 1 and Figures 2a to 2d In some embodiments, the anti-skid pattern 1013 includes a plurality of first grooves 10131 distributed at intervals, and at least one groove wall of each first groove 10131 is at a first angle a with the edge of the gasket body 101, the first angle a being greater than or equal to 30° and less than or equal to 60°.

[0041] To reduce the smoothness of the first surface 1011, a plurality of first grooves 10131 can be provided, which can be arranged in an array or staggered. The groove of the first groove 10131 is flush with the first surface 1011, and the adjacent two first grooves 10131 are separated by the solid structure 10132 formed by the material of the gasket body 101 itself, and the side wall of the solid structure 10132 is the groove wall of the first groove 10131. Generally, the edge of the product 2 is parallel to the transverse direction (such as the X direction in Figure 2a ) and the longitudinal direction (such as the Y direction in Figure 2a ), and the product 2 is usually moved in the transverse direction or the longitudinal direction during transportation. Therefore, if the side wall of the solid structure 10132 is also parallel to the transverse direction and the longitudinal direction, the solid structure 10132 may be bent under the action of the inertia of the product 2 when the product 2 moves in the transverse direction or the longitudinal direction, thereby causing relative movement between the product 2 and the gasket body 101. To avoid the above situation, at least part of the solid structure 10132 can be arranged at a first angle α with the edge of the gasket body 101, 30°≤α≤60°, or 120°≤α≤150°.

[0042] As shown in Figure 2a , in some embodiments, the plurality of first grooves 10131 are parallel strip-shaped grooves, and both ends of the strip-shaped grooves extend to the edge of the gasket body 101 to form a first air port 10133 that is in communication with the outside.

[0043] When the first groove 10131 is a strip-shaped groove, both ends of each strip-shaped groove penetrate the side wall of the gasket body 101 to form an opening that communicates with the first surface 1011, i.e., the first air port 10133. When the product 2 is placed on the anti-skid pad 1 of the present embodiment, the bottom surface of the product 2 is in contact with the first surface 1011, and the air between the bottom surface of the product 2 and the first surface 1011 is squeezed out, and a local negative pressure environment is formed between them due to the reduction of air compared with the outside air. However, since the first air port 10133 is always in communication with the outside air, during the process of separating the bottom surface of the product 2 from the first surface 1011 by a picker or a mechanical hand or the like, the air in the first groove 10131 flows to the bottom surface of the product 2 and the first surface 1011, and the outside air can flow into the first groove 10133 to continuously supplement, until the air pressure between the bottom surface of the product 2 and the first surface 1011 is equal to the air pressure of the outside air.

[0044] That is, when the product 2 is grabbed from the anti-skid pad 1 of the present embodiment, the first air port 10133 can avoid the negative pressure environment formed between the anti-skid pad 1 (and the tray connected with the anti-skid pad 1) and the product 2, so that the anti-skid pad 1 is adhered to the product 2 and rises with the product 2.

[0045] As shown in Figures 2b to 2d some embodiments, the first groove 10131 has a cross-sectional shape parallel to the first surface 1011 that is a closed polygon.

[0046] For example, the cross-sectional shape of the first groove 10131 parallel to the first surface 1011 can be a triangle, as shown in Figure 2b ; or a quadrilateral, as shown in Figure 2c ; or a pentagon, a hexagon, etc., as shown in Figure 2d .

[0047] In this embodiment, the complete first groove 10131 only has a slot opening flush with the first surface 1011 and has no other openings. When the product 2 is placed on the anti-skid pad 1 of this embodiment, the bottom surface of the product 2 is in contact with the first surface 1011, and the air between the bottom surface of the product 2 and the first surface 1011 is squeezed out, and a local negative pressure environment is formed between the two due to the reduction of air compared to the external air. The first groove 10131 becomes a closed space after the slot opening is covered by the bottom surface of the product 2, and the air inside is not squeezed out. During the process of the product 2 being grabbed by a suction cup or a mechanical hand and other equipment so that the bottom surface of the product 2 is separated from the first surface 1011, the air in the first groove 10131 flows to the bottom surface of the product 2 and the first surface 1011 to supplement, at the same time, external air enters between the bottom surface of the product 2 and the first surface 1011 to supplement, until the air pressure between the bottom surface of the product 2 and the first surface 1011 is equal to that of the external air.

[0048] This embodiment can retain air through the first groove 10131, and when the product 2 is grabbed from the anti-skid pad 1 of this embodiment, the air retained in the first groove 10131 can supplement the local negative pressure environment between the product 2 and the pad body 101; compared with the first surface 1011 without a groove, the local negative pressure environment can be restored to the same as the external environment more quickly, to some extent, avoiding the negative pressure environment formed between the anti-skid pad 1 (and the tray connected with the anti-skid pad 1) and the product 2, so that the anti-skid pad 1 is adhered to the product 2 and rises up.

[0049] As shown in Figures 2a to 2d some embodiments, the minimum spacing distance a between two adjacent first grooves 10131 is 0.2mm to 0.5mm; in the first groove 10131, the distance b between the two opposite groove walls is 1mm to 2mm, or the distance b' between the groove wall and the opposite corner is 1mm to 2mm.

[0050] In summary, the larger the area of ​​the first groove 10131, the more effective it is in preventing the anti-slip pad 1 from sticking to the product 2. However, since the area of ​​the first surface 1011 is fixed, if the area of ​​the first groove 10131 increases, the width of the solid structure 10132 separating the first groove 10131 will decrease accordingly. If the width of the solid structure 10132 is too small, its own strength will be weakened. When the product 2 is placed on the first surface 1011 of the pad body 101, the solid structure 10132 will bend due to the weight of the product 2 and cannot reliably support the product 2.

[0051] Therefore, in order to both enable the first groove 10131 to achieve the effect of adjusting the negative pressure environment between the product 2 and the first surface 1011, and to ensure that the solid structure 10132 provides reliable support for the product 2, in this embodiment, the minimum interval between two adjacent first grooves 10131, that is, the width of the solid structure 10132 between two adjacent first grooves 10131, is a, 0.2mm≤a≤0.5mm; in each first groove 10131, when the first groove 10131 is a strip groove or the cross-sectional shape of the first groove 10131 is a quadrilateral or hexagonal shape, the distance between the two opposite groove walls is b, 1mm≤b≤2mm; when the cross-sectional shape of the first groove 10131 is a triangle or pentagonal shape, the distance between the groove wall and the opposite corner is b', 1mm≤b'≤2mm.

[0052] like Figures 2a to 2d As shown, in some embodiments, the gasket body 101 is further provided with a first hollow area 1014, the two ends of the first hollow area 1014 extending along a direction parallel to the first surface 1011 to two adjacent edges or two opposite edges of the gasket body 101, so as to form a second air vent 10141 communicating with the outside.

[0053] To further prevent adhesion between the product 2 and the gasket body 101 due to the negative pressure environment, in this embodiment, a first hollow area 1014 is provided in the gasket body 101. The two ends of the first hollow area 1014 penetrate the two side walls of the gasket body 101 to form an air passage for air flow. Air can flow into the first hollow area 1014 from the first second air port 10141 and then flow out through the second second air port 10141 to increase the air flow speed on the side of the product 2 facing the gasket body 101.

[0054] In some embodiments, the gasket body 101 is a silicone layer with a Shore hardness greater than or equal to 30 and less than or equal to 50.

[0055] If the hardness of the gasket body 101 is less than 30 Shore, on the one hand, the solid structure 10132 in the anti-skid pattern 1013 is easy to deform, and cannot effectively support the product 2; on the other hand, the adsorption force between the first surface 1011 and the product 2 is enhanced, and the product 2 is more likely to be adhered when separated from the first surface 1011. If the hardness of the gasket body 101 is greater than 50 Shore, the adsorption force of the first surface 1011 to the product 2 is too low, and the relative sliding between the product 2 and the anti-skid pad 1 cannot be avoided during the transportation of the product.

[0056] Based on the same inventive concept, in combination with the description of the anti-skid pad 1 of each of the above embodiments, the present embodiment provides a tray having the corresponding technical effects of the anti-skid pad 1 of each of the above embodiments, which will not be described here.

[0057] As shown in Figure 3 , the present embodiment provides a tray, which comprises: a tray body 3 provided with a containing groove 301 for accommodating a product 2; and an anti-skid pad 1 as described in each of the above embodiments, which is arranged in the containing groove 301, and the static electricity leading-out layer 102 is connected to the groove bottom of the containing groove 301 for leading out the static electricity of the anti-skid pad 1 through the tray body 3.

[0058] For example, the tray body 3 can be grounded through a conductive device such as an electrical connection line. When a plurality of trays are stacked, since the tray body 3 of the upper tray is in contact with the tray body 3 of the lower tray, the electrical connection line for grounding can be arranged only on the tray body 3 of the lowermost tray, and the static electricity of the tray body 3 of the upper tray is transmitted to the tray body 3 of the lower tray until it is transmitted to the tray body 3 of the lowermost tray, and finally led out through grounding, as shown in Figure 4 , the static electricity flow (or static electricity dissipation path) between the stacked trays is shown by the dashed arrows in the figure.

[0059] In the interior of the tray, as shown in Figure 5 , the product static electricity enters the gasket body 101 through the anti-skid pattern 1013 in contact with the product 2, then passes through the static electricity leading-out layer 102 into the tray body 3, and finally is led out.

[0060] The product 2, such as an OLED flexible display panel, is placed in the containing groove 301 and in contact with the anti-skid pad 1 arranged at the bottom of the containing groove 301. During the transportation process, the anti-skid pad 1 can prevent the product 2 from sliding in the containing groove 301, and can also lead out the product static electricity remaining in the product 2 through the anti-skid pad 1 and the tray body 3.

[0061] For example, one, two or more containing grooves 301 can be arranged in the same tray body 3, as shown in Figure 3 , Figure 6 and Figure 7The tray body 3 shown in the figure is provided with four accommodation grooves 301, and adjacent two accommodation grooves 301 can communicate with each other to allow air flow.

[0062] Before or after use, the tray body 3, especially the accommodation grooves 301, is usually cleaned to avoid dust and sundries remaining in the accommodation grooves 301. After cleaning and drying, water may still remain on the bottom edge of the accommodation groove 301, and if the water on the bottom of the accommodation groove 301 flows to and contacts the product 2 placed on the bottom during the transportation of the product 2, the water may erode the product 2 and cause damage to the product 2.

[0063] To avoid the above situation, as shown in Figure 3 and Figure 7 , in some embodiments, the bottom of the accommodation groove 301 is provided with a protruding boss 302 for supporting the product 2, and the non-slip pad 1 is arranged on the side of the boss 302 away from the bottom.

[0064] In this embodiment, after the product 2 is placed in the accommodation groove 301, it will contact the non-slip pad 1 above the boss 302, and even if there is water in the accommodation groove 301, the water will be in the bottom of the accommodation groove 301 below the boss 302 and cannot contact the product 2 by crossing the boss 302 and the non-slip pad 1, so the product 2 and the water can be kept away from each other, and the product 2 can be effectively protected.

[0065] As shown in Figure 7 , in some embodiments, the boss 302 in each accommodation groove 301 includes a first sub-boss 3021 and a second sub-boss 3022 symmetrically and spaced apart, and a reinforcing rib 303 protruding from the bottom is arranged between the first sub-boss 3021 and the second sub-boss 3022; the product 2 includes at least one suction area for connecting with a suction cup, and when the boss 302 supports the product 2, the first sub-boss 3021 and / or the second sub-boss 3022 covers the entire suction area in the orthographic projection of the product 2.

[0066] Since the thickness of the bottom of the accommodation groove 301 in the tray body 3 is thin, in order to increase the rigidity of this area and reduce deformation, a reinforcing rib 303 can be arranged at the middle position of the bottom of the accommodation groove 301 to increase the thickness of the tray body 3 at least at the center of the bottom and adjacent positions. However, in order to avoid adversely affecting the function of supporting the product 2 achieved by the boss 2, the height of the reinforcing rib 303 does not exceed the total height of the boss 302 and the non-slip pad 1.

[0067] In addition, in the present embodiment, the boss 302 is used as a structure for supporting the product 2, and the reinforcing rib 303 is used as a structure for increasing the rigidity of the bottom of the accommodation groove 301. The functions of the boss 302 and the reinforcing rib 303 are different, and the boss 302 and the reinforcing rib 303 cannot be arranged at the same position of the bottom of the accommodation groove 301 at the same time. Therefore, the arrangement position and the coverage area of the boss 302 and the reinforcing rib 303 need to be limited.

[0068] When the product 2 is an OLED flexible display panel, the product 2 is usually grabbed by a suction cup to be taken out of the accommodation groove 301. In the grabbing process, the suction cup needs to press the product 2 downward after being in contact with the top surface of the product 2 to expel the air between the suction cup and the product 2 to form a negative pressure, so that the suction cup and the product 2 are attracted. Therefore, in order to resist the downward pressure of the suction cup on the product 2, the boss 302 is arranged at least at the position corresponding to the suction cup. As shown in FIG. 6, the positions marked by the circles in the figure are the positions where the projection of the suction area of the product 2 on the boss 302 is located. These positions are partially located on the first sub-boss 3021 and partially located on the second sub-boss 3022. That is, the first sub-boss 3021 and the second sub-boss 3022 can at least form reliable support for the product 2 at the positions corresponding to the suction area of the product 2, so as to avoid damage to the product 2 when the product 2 is pressed by the suction cup. Figure 7

[0069] In some embodiments, a channel for air flow is arranged between the first sub-boss 3021 and the second sub-boss 3022, and the reinforcing rib 303 is arranged in the channel, as shown in FIG. 7. Figure 7 At the same time, the channel corresponds to the first hollow area 1014 of the gasket body 101, that is, the projection of the first hollow area 1014 on the bottom of the accommodation groove 301 coincides with the projection of the channel between the first sub-boss 3021 and the second sub-boss 3022 on the bottom of the accommodation groove 301.

[0070] In some embodiments, the static electricity leading-out layer 102 includes conductive cloth connected to the gasket body 101 and the tray body 3, respectively.

[0071] The conductive cloth can be a metal conductive cloth, and the two sides of the conductive cloth are coated with solid glue as an adhesive to form the static electricity leading-out layer 102. When the static electricity leading-out layer 102 is connected to the gasket body 101 and the tray body 3, the redundant solid glue between the conductive cloth and the gasket body 101 and the redundant solid glue between the conductive cloth and the tray body 3 can be removed by extrusion under an external force (since the solid glue still exists in the fiber gap of the conductive cloth, the reliable connection between the static electricity leading-out layer 102, the gasket body 101 and the tray body 3 can be ensured), so as to ensure that the conductive cloth is connected to the gasket body 101 and the tray body 3, respectively, and ensure that the product static electricity can be conducted from the gasket body 101 to the tray body 3 through the static electricity leading-out layer 102.​

[0072] In some embodiments, the surface resistances of the tray body 3, the gasket body 101 and the static electricity leading-out layer 102 are all greater than or equal to 1x10 6 Ω and less than 1x10 9 Ω, the volume resistances of the three are all greater than or equal to 1x10 6 Ω and less than 1x10 9 Ω, and the triboelectric voltages of the three are all less than 100V.

[0073] If the surface resistances and / or the volume resistances of the tray body 3, the gasket body 101 and the static electricity leading-out layer 102 are less than 1x10 6 Ω, current is easily formed, static electricity cannot be dissipated slowly, and the static electricity backstroke effect can be caused. If the surface resistances and / or the volume resistances of the above three are greater than or equal to 1x10 9 Ω, static electricity is dissipated too slowly, the static electricity dissipation speed is less than the static electricity generation speed, and thus static electricity accumulates, resulting in a high static electricity residual in the product 2 and causing damage to the product 2.

[0074] Therefore, the surface resistances and the volume resistances of the tray body 3, the gasket body 101 and the static electricity leading-out layer 102 are all set to be greater than or equal to 1x10 6 Ω and less than 1x10 9 Ω, which can eliminate the static electricity backstroke effect and the static electricity accumulation effect, and ensure the safety of the product 2.

[0075] It should be noted that the surface resistance in the present embodiment includes the inner surface resistance and the outer surface resistance of the structure.

[0076] The triboelectric voltages of the above three are all greater than 100V, which can make the three have the anti-static function. If the triboelectric voltage of at least one of the above three is greater than 100V, electric shock can occur, causing damage to the product 2.
