Description

Technical Field

[0001] This utility model belongs to the field of resistor manufacturing technology, and in particular to a metal oxide resistor transfer tray. Background Technology

[0002] Metal oxide resistors are polycrystalline voltage-sensitive ceramic materials, belonging to the category of hard and brittle materials. High safety requirements are placed on their transfer and storage between different production processes, as any physical defects can adversely affect their electrical performance. Currently, resistors are typically stored and transferred in stacks within plastic boxes, with the top and bottom surfaces in direct contact and some space left on the sides. During transfer, significant shaking cannot prevent friction and collisions between the resistors and between the resistors and the plastic box, causing edge damage and affecting performance. This transfer method is insufficient to meet the demands of high-quality, high-efficiency production. Utility Model Content

[0003] In view of the above problems, the purpose of this application is to provide a metal oxide resistor transfer tray, which enables the independent placement of individual resistors, vertical stacking of multiple layers of the tray, convenient handling by operators, and safe and controllable storage quantity and transfer placement of resistors.

[0004] To achieve some or all of the above objectives or other objectives, this application provides the following technical solution: a metal oxide resistor transfer tray, the tray including a tray surface and a periphery; a frame of the periphery is connected to the tray surface, and a frame is formed between the tray surface and the periphery; the tray surface is provided with a plurality of circular grooves and two or more retrieval slots, and a retrieval slot is provided on each side of the symmetrical center of the circular grooves; the depth of the circular grooves is higher than the height of the resistors, and the resistors are placed in the circular grooves; the frame of the periphery connected to the tray surface is smaller than the frame of the periphery away from the tray surface; a plurality of trays are stacked vertically, with gaps between adjacent trays; the bottom of the adjacent upper circular groove is set in the lower circular groove; the periphery of the adjacent upper tray rests on the periphery of the lower tray.

[0005] Furthermore, the end face of the resistor sheet contacts the bottom surface of the circular groove, and a 1mm gap is left between the side surface of the resistor sheet and the inner wall of the circular groove.

[0006] Furthermore, the radius of the circular groove is 53.5 mm, and the depth of the circular groove is 27 mm.

[0007] Furthermore, the retrieval slot has a width of 34.9 mm and a depth of 8.02 mm.

[0008] Furthermore, the tray is rectangular, with a length of 410 mm, a width of 280 mm, and a height of 25 mm; the tray has concave and convex surfaces around its perimeter.

[0009] Furthermore, the bottom edge of the circular groove is rounded.

[0010] Furthermore, the plate surface is provided with 6 circular grooves, three in a row, and a retrieval slot is provided between two adjacent circular grooves in each row.

[0011] Furthermore, the tray is made of plastic.

[0012] Compared with existing technologies, the advantages of this invention are as follows: Each resistor is independently placed in a circular groove, protecting each individual resistor and effectively preventing quality loss caused by collisions between resistors; the resistors are placed vertically in multiple layers without contact, achieving stable multi-layer positioning and ensuring the quantity and safety of resistor transfer; the resistor trays are stacked on a dedicated metal pallet for lightweight transfer using an electric forklift. The bottom of the adjacent upper circular groove is set within the lower circular groove, and the perimeter of the tray is smaller than the perimeter of the tray, ensuring a snug fit between the upper and lower layers and achieving relative stability in the position of each pallet. This prevents the upper and lower pallets from separating due to tilting during transfer, thus better protecting the resistors. Attached Figure Description

[0017] To make the structure and function of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] See appendix Figure 1-3A metal oxide resistor sheet transfer tray includes a tray surface 1 and a periphery 2; one edge of the periphery 2 is connected to the tray surface 1, and a frame is formed between the tray surface 1 and the periphery 2; the tray surface 1 is provided with a plurality of circular grooves 3 and two or more retrieval slots 4, and a retrieval slot 4 is provided on each side of the symmetrical center of the circular grooves 3; the depth of the circular grooves 3 is higher than the height of the resistor sheet 7, and the resistor sheet 7 is placed in the circular grooves 3; the upper edge 5 of the periphery 2 connected to the tray surface 1 is smaller than the lower edge 6 of the periphery 2 away from the tray surface 1; a plurality of trays are stacked vertically, with gaps between adjacent trays; the bottom of the adjacent upper circular groove 3 is set in the lower circular groove 3; the periphery 2 of the adjacent upper tray rests on the periphery 2 of the lower tray.

[0019] Based on the above technical solution, the depth of the circular groove is higher than the height of the resistor sheet. When multiple trays are stacked vertically, the bottom of the upper tray is placed on the upper surface of the lower resistor sheet and partially extends into the circular groove of the lower tray, which serves as a positioning function. Hand-held retrieval slots are designed at both ends of the tray groove to facilitate the operation of the operator. The upper frame 5 of the perimeter 2 connected to the tray surface 1 is smaller than the lower frame 6 of the perimeter 2 that is far away from the tray surface 1, so as to achieve multi-layer positioning stability and ensure the quantity and safety of resistor sheet transfer.

[0020] The end face of the resistor 7 contacts the bottom surface of the circular groove 3, and a 1mm gap is left between the side surface of the resistor 7 and the inner wall of the circular groove 3; to prevent wear caused by contact between the side surface of the resistor and the inner wall of the groove.

[0021] The circular groove 3 has a radius of 53.5 mm and a depth of 27 mm.

[0022] The retrieval slot 4 has a width of 34.9 mm and a depth of 8.02 mm.

[0023] The tray is rectangular, with a length of 410 mm, a width of 280 mm, and a height of 25 mm. The tray has a concave-convex surface around its perimeter. This unique uneven design enhances the stability between the stacked trays, prevents them from shaking during transportation, further reduces the possibility of damage to the resistor sheet 7, and avoids the situation where there is no gap between the perimeters of two adjacent trays, making it difficult to separate them after adsorption.

[0024] The bottom edge of the circular groove 3 is rounded; when the resistor is placed in the circular groove, the bottom of the resistor is stably positioned in accordance with the size of the bottom of the circular groove.

[0025] The disc surface 1 is provided with 6 circular grooves 3, three in a row, and a retrieval slot 4 is provided between two adjacent circular grooves 3 in each row.

[0026] Based on the above technical solution, six resistor sheets can be placed independently on a single pallet, protecting each individual resistor sheet and effectively avoiding quality loss caused by collisions between resistor sheets; the resistor sheets are placed vertically in multiple layers without contact, achieving multi-layer positioning stability and ensuring the quantity and safety of resistor sheet transfer; handles are designed at both ends of the pallet groove for easy handling by operators; the resistor sheet pallets are stacked on a special metal pallet and transported in a lightweight manner using an electric forklift.

[0027] The tray is made of plastic.

[0028] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
