Description

Technical Field

[0001] This invention relates to the field of tray technology, and in particular to a functional substrate tray. Background Technology

[0002] Substrate trays are core tooling in the electronics manufacturing industry used to support, transport, and store precision electronic components such as PCBs, FPCs, and semiconductor packaging substrates. As the electronics industry develops towards multi-variety, small-batch, and rapid iteration, the specifications of substrates produced by companies are increasing, placing ever higher demands on the versatility, stacking accuracy, and structural strength of trays. Currently, most mainstream substrate trays on the market adopt an integral injection-molded structure, which has the following drawbacks: 1. Poor versatility: Existing substrate trays can only accommodate a single substrate specification, resulting in high mold investment and tray inventory costs; 2. Insufficient structural strength: To reduce costs, existing trays generally adopt a thin-walled design, and the reinforcing rib structure is unreasonable, making them prone to bending and deformation after long-term use. Summary of the Invention

[0003] The purpose of this invention is to provide a functional substrate tray to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a functional substrate tray, comprising a tray body, wherein a first protrusion is provided on the outer walls of both sides of the tray body, and a second protrusion is provided on the outer walls of the other two sides of the tray body, and a positioning groove is provided at the intersection of the first protrusion and the second protrusion, a first step is provided on one side of the second protrusion, a second step is provided at both ends of the first step, a third step is provided on one side of the second step, and a fourth step is provided on one side of the first protrusion, and the first step, the second step, the third step and the fourth step are integrally formed on the tray body.

[0005] The lower surface of the first protrusion is provided with a first groove, the lower surface of the second protrusion is provided with a second groove, a positioning boss is provided at the position where the second groove intersects with the first groove, and a positioning groove is provided on the positioning boss.

[0006] The first protrusion has a handle groove.

[0007] Both the first and second grooves are fixedly connected with cross-shaped reinforcing ribs, and both the first and second grooves are fixedly connected with horizontal reinforcing ribs.

[0008] The lower surface of the tray body is fixedly connected with a mesh-like reinforcing rib.

[0009] The lower surface of the tray body is integrally formed with multiple gate bosses.

[0010] The height of the first step is lower than that of the second step, the height of the second step is lower than that of the third step, and the upper surfaces of the third and fourth steps are at the same horizontal level.

[0011] The functional substrate tray provided by this invention has the following advantages: Through the layered bearing and limiting design of the first to fourth steps, one tray can simultaneously adapt to substrates of various specifications, greatly reducing the number of molds and the backlog of tray inventory, and reducing the overall production cost; The cross-shaped reinforcing ribs and horizontal reinforcing ribs reinforce the convex structure, combined with the mesh reinforcing ribs at the bottom of the tray, comprehensively improving the overall rigidity and deformation resistance of the tray, avoiding bending deformation after long-term use, and extending the service life.
