[0002] FPC is a flexible printed circuit board, usually made of polyimide or polyester material. It has good flexibility and high temperature resistance. It is widely used in electronic devices because they can provide complex circuit connections in a limited space and can withstand multiple bending and deformation, which helps to reduce the weight of the equipment and improve design flexibility. Pallets are usually used in the production and transportation of FPCs.

[0003] When moving, loading or transporting FPC, it is usually necessary to place it on a pallet, which can reduce friction and collision with other objects, avoid damage caused by external forces, and facilitate management and transportation, as well as quality control and management.

[0004] Existing FPC pallets usually have a smooth bottom and do not have a stacking function, which leads to low efficiency in the loading or transportation process and cannot adapt to the fast-paced production needs. At the same time, the FPC is placed on the pallet without any limit, which makes it easy for the FPC to fall off when the pallet is moved, causing damage to the FPC. For this reason, technical personnel in this field have proposed a new type of pallet to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a new type of pallet, which aims to improve the problem that the FPC pallet in the existing technology does not have the stacking function, resulting in low efficiency in the loading or transportation process, and the FPC is easily detached and dropped when the pallet moves, causing damage.

[0007] Furthermore, the limiting assembly includes a plurality of elastic limiting strips, and the plurality of elastic limiting strips are fixedly connected to the side of the placement groove. The side of the placement groove is fixedly connected with a plurality of protrusions, and the protrusions are arranged below the elastic limiting strips.

[0008] Furthermore, the first ridge matches the shape of the first receiving groove, and the second ridge matches the shape of the second receiving groove.

[0009] Furthermore, an annular groove is provided at the bottom of the placement groove, and the depth of the annular groove is smaller than the depth of the placement groove.

[0010] Furthermore, a reinforcing rib is fixedly connected to the middle portion of the lower surface of the disk body, and a rubber pad is fixedly connected to the bottom edge of the disk body.

[0011] Furthermore, a fool-proof cut corner is provided at the lower left corner of the disk body.

[0012] Furthermore, the interior of the elastic limiting strip is a hollow structure, and the protrusion is semicircular.

[0013] Furthermore, the angle between the side of the disk and the horizontal plane is 105°.

[0014] The utility model has the following beneficial effects:

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a new type of tray, including a tray body 1, which is made of polystyrene in one piece, with low production cost. Two first ridges 2 are provided on the front and back sides of the top of the tray body 1, and a first receiving groove 3 is provided on the bottom of the tray body 1 just below the first ridge 2. The first ridge 2 and the first receiving groove 3 are engaged with each other to prevent the two tray bodies 1 from moving longitudinally after being stacked together. Second ridges 4 are provided on the left and right sides of the bottom of the tray body 1, and a second receiving groove 5 is provided on the top of the tray body 1 just above the second ridge 4. The engagement of the second ridge 4 and the second receiving groove 5 can prevent the two tray bodies 1 from moving longitudinally after being stacked together. After the trays 1 are stacked together, they are moved laterally. A plurality of placement grooves 6 are provided on the upper surface of the tray 1 for placing FPCs. Grabbing grooves 7 are provided at multiple corners of the placement grooves 6. The grabbing grooves 7 are used to facilitate the placement of the FPCs. The two placement grooves 6 are connected laterally by two grabbing grooves 7. The shapes of the first ridge 2 and the first receiving groove 3 match, and the shapes of the second ridge 4 and the second receiving groove 5 match. A reinforcing rib 11 is fixedly connected to the middle of the lower surface of the tray 1 to improve the overall structural strength. A rubber pad 12 is fixedly connected to the bottom edge of the tray 1 to prevent sliding during placement.

[0024] Specifically, when using the tray, the FPC is placed in the placement groove 6. The multiple elastic limiting strips 8 and the protrusions 9 on the inner side of the placement groove 6 are hollow structures and are elastic parts themselves. Then, after the FPC is placed in the placement groove 6, it will rebound and exert pressure on the FPC, thereby limiting it, preventing the FPC from falling off during the movement of the tray, preventing it from being damaged and causing unnecessary losses. When splicing two trays, they can be aligned through the anti-fool-proof cut corner 13 at the lower left corner of the tray body 1, and then the two tray bodies 1 are stacked together so that the first accommodating groove 3 opened at the bottom of the upper tray body 1 is aligned with the lower tray body 1. The first ridge 2 on the top is engaged, and the second ridge 4 on the bottom of the upper disk body 1 is inserted into the second receiving groove 5 on the top of the lower disk body 1, thereby completing the stacking between the two disk bodies 1, which can reduce the occupied space, facilitate transportation and movement, improve production efficiency, and is beneficial to batch management and protection of products. The grabbing groove 7 can facilitate the storage and access of FPC, and the structural strength of the tray can be improved by the reinforcing rib 11 to make it more durable. The rubber pad 12 at the bottom of the disk body 1 can increase the friction with the contact surface to avoid sliding, and at the same time reduce the vibration of the tray to avoid damage to the FPC caused by vibration.

[0025] Reference Figure 1 and Figure 3 A limiting component is provided on the inner side of the placement groove 6, and the limiting component is used to limit the movement of the circuit board. The limiting component includes a plurality of elastic limiting strips 8, and the plurality of elastic limiting strips 8 are fixedly connected to the side of the placement groove 6. The FPC can be limited from leaving the placement groove 6 through the plurality of elastic limiting strips 8. The side of the placement groove 6 is fixedly connected with a plurality of protrusions 9. The interior of the elastic limiting strip 8 is a hollow structure, and the protrusion 9 is a semicircular arc shape. The FPC can be clamped by the plurality of protrusions 9 to ensure stability during movement. The protrusion 9 is provided below the elastic limiting strip 8, and an annular groove 10 is provided at the bottom of the placement groove 6. The depth of the annular groove 10 is less than the depth of the placement groove 6.

[0026] Specifically, when placing the FPC on the tray, it can be placed in the placement groove 6. The multiple elastic limit strips 8 and the protrusions 9 are all made of elastic materials, so that the protrusions 9 can generate elastic force to put pressure on the FPC, limiting its movement in the placement groove 6. At the same time, the multiple elastic limit strips 8 can limit the FPC from popping out, so that the FPC can remain stable during the movement of the tray and will not fall off the tray, avoiding damage caused by falling. The annular groove 10 can position the FPC so that it maintains consistency in direction when placed.

[0027] Reference Figure 1The lower left corner of the tray body 1 is provided with an anti-mistake cut corner 13. The anti-mistake cut corner 13 can be used to align two trays when they are stacked to prevent the trays from being placed in the wrong direction. The tray body 1 is made of polystyrene as a whole. Polystyrene has good insulation properties. At the same time, the material has strong toughness and good wear resistance. The angle between the side of the tray body 1 and the horizontal plane is 105°, which is convenient for demolding the tray after molding.

[0028] Specifically, when stacking the trays, the anti-fouling cut corners 13 can be used for alignment so that the directions of the two trays are aligned to avoid incorrect installation of the FPC during placement. Anti-static polystyrene is used as the raw material of the tray body 1. At the same time, the surface of the tray body 1 is covered with an anti-static coating, and the surface anti-static value of the tray body 1 is 10 8 —10 11 Ω, used in conjunction with the anti-static coating on the surface, can effectively avoid the generation of static electricity and prevent the damage of FPC caused by static electricity. The side of the tray body 1 is set at an angle of 105° with the horizontal plane, which can facilitate demoulding when producing the tray.

[0029] Working principle: When using this tray, first place the FPC in the multiple placement grooves 6 opened on the upper surface of the tray body 1. The FPC can be limited by the multiple elastic limit strips 8 and protrusions 9 on the inside of the placement groove 6 to prevent the FPC from falling off and being damaged during the movement of the tray. Then, when stacking the two tray bodies 1, align them through the anti-misalignment cut corners 13. Then, stack the two tray bodies 1 together so that the first receiving groove 3 opened at the bottom of the upper tray body 1 is engaged with the first ridge 2 on the top of the lower tray body 1, and the second ridge 4 at the bottom of the upper tray body 1 is inserted into the second receiving groove 5 on the top of the lower tray body 1, thereby completing the stacking between the two tray bodies 1, saving storage space, and facilitating the transportation or loading of the FPC, thereby improving production efficiency. The grabbing groove 7 is used to facilitate the removal and placement of the FPC in the placement groove 6, thereby improving the efficiency of taking. The tray body 1 set at the bottom of the tray body 1 can improve the overall structural strength, and the tray body 1 is made of polystyrene and coated with an anti-static coating on the surface, which can effectively prevent static electricity from damaging the FPC.
