[0026] Figure 1 The figure shows an application scenario diagram of the support plate assembly provided by an embodiment of the present disclosure. Figure 1 As shown, the pallet assembly 10 includes a base assembly 100 and at least two buffer assemblies 200. The base assembly 100 is configured to carry the sheet carrier 2. The at least two buffer assemblies 200 are arranged relatively along the first direction X1 and are both connected to the base assembly 100. The buffer assembly 200 is elastic in the vertical direction to provide a buffering force for the sheet carrier 2 during the contact between the buffer assembly 200 and the sheet carrier 2.

[0027] The buffer assembly 200 of the pallet assembly 10 provides a buffering force for the sheet carrier 2 during the contact process with the sheet carrier 2, so that the sheet carrier 2 slowly falls to the base assembly 100, thereby reducing the probability of the sheet carrier 2 having problems such as edge collapse and foot collapse when the sheet carrier 2 contacts the base assembly 100.

[0031] The first receiving groove 2101 and the second receiving groove 2201 are used to accommodate the elastic member 2310 to improve the stability and accuracy of the upward buffering force provided by the elastic member 2310 to the bearing assembly 220. In addition, the first receiving groove 2101 and the second receiving groove 2201 can also protect the elastic member 2310.

Exemplarily, in the vertical direction, the pressing piece 2213 has a through slot 2223 and a clamping slot 2233, and the through slot 2223 and the clamping slot 2233 are communicated in the horizontal direction. The bearing piece 2212 further has a clamping portion 2231 located at the side end of the bearing portion 2230 and connected with the bearing portion 2230. The clamping portion 2231 is located in the clamping slot 2233, the top of the clamping portion 2231 abuts against the slot bottom of the clamping slot 2233, the bottom of the clamping portion 2231 abuts against the top of the support piece 2211, the bearing portion 2230 passes through the through slot 2223, and the pressing piece 2213 is detachably connected with the support piece 2211.

[0038] The bearing assembly 220 has a simple structure, is convenient for quick disassembly and installation, and in addition, the bearing piece 2212 is convenient for quick replacement in a simple mounting mode.

[0039] Exemplarily, the material of the support piece 2211 is a non-metal material, which can be ceramic or plastic. Exemplarily, the material of the bearing piece 2212 is a non-metal material, which can be ceramic or plastic. Exemplarily, the material of the pressing piece 2213 is a non-metal material, which can be ceramic or plastic.

[0040] Exemplarily, the bearing portion 2230 has an arc-shaped bearing surface for bearing the sheet carrier 2, so as to realize linear contact between the bearing portion 2230 and the sheet carrier 2 and minimize the contact area between the bearing portion 2230 and the sheet carrier 2.

[0041] In some embodiments, as shown in Figure 4 The first support portion 2110 further has a guide hole 2111, and the buffer assembly 200 further comprises a guide piece 240 connected with the second support portion 2210 and penetrating into the guide hole 2111.

[0042] The guide piece 240 guides the movement of the bearing assembly 220 in the vertical direction, so as to further improve the accuracy of the bearing assembly 220 in bearing the movement of the sheet carrier 2 in the vertical direction, and enable the sheet carrier 2 to accurately fall onto the bottom support assembly 100.

[0043] Exemplarily, the first support portion 2110 has two guide holes 2111, and the buffer assembly 200 comprises two guide pieces 240 penetrating into the two guide holes 2111 respectively.

[0044] In some embodiments, as shown in Figure 1 and Figure 2 As shown, the pallet assembly 10 also includes at least two limiting assemblies 300, which are respectively arranged adjacent to at least two buffer assemblies 200. The limiting assemblies 300 can abut against the end face of the sheet carrier 2 in the extension direction of the sheet carrier 2 to limit the sheet carrier 2.

[0045] In some embodiments, as Figure 2 and Figure 3 As shown, the limiting assembly 300 includes a first axle 310 and a first roller 320. The first axle 310 extends along a second direction X2 and is connected to the base assembly 100. The second direction X2 is perpendicular to the first direction X1.

It is capable of abutting the end surface of the sheet carrier 2 in the direction in which the sheet carrier 2 extends.

[0046] The first rollers 320 roll against the end surface of the sheet carrier 2 to reduce friction between the stop assembly 300 and the end surface of the sheet carrier 2. Furthermore, the first rollers 320 can correct the position of the sheet carrier 2 during rolling, allowing the sheet carrier 2 to accurately land on the base assembly 100 and be confined between the two first rollers 320. The distance between the two stop assemblies 300 can be set based on the dimensions of the sheet carrier 2 in its extension direction.

[0047] In some embodiments, the pallet assembly 10 further includes a plurality of second axles 400 and a plurality of second rollers 500. The plurality of second axles 400 extend along the first direction X1, are connected to the base assembly 100, and are located on both sides of the buffer assembly 200. The plurality of second rollers 500 are respectively mounted on the plurality of second axles 400. The second rollers 500 are rotatably connected to the corresponding second axles 400 and are configured to carry the sheet carrier 2.

[0048] The second roller 500 is used to support the sheet carrier 2 to reduce the contact area between the base assembly 100 and the sheet carrier 2, thereby further reducing the probability of the sheet carrier 2 having problems such as edge chipping and foot chipping. In addition, the second roller 500 is used to be in rolling connection with the sheet carrier 2 to reduce the friction between the second roller 500 and the sheet carrier 2, thereby further reducing the probability of the sheet carrier 2 having problems such as edge chipping and foot chipping.

[0049] For example, Figure 3 As shown, a second axle 400 and a second roller 500 are disposed on either side of a buffer assembly 200. The second roller 500 is mounted on the second axle 400 and rotatably connected to the second axle 400. The four second rollers 500 support both ends of the sheet carrier 2, thereby improving the stability of the sheet carrier 2 supported by the pallet assembly 10.
