Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling for producing micro-sized metal packaging cover plates, in particular to a drying material tray in the production process of electronic packaging metal cover plates. Background Art
[0002] With the miniaturization of electronic components, electronic packaging metal covers are also developing towards thinning, refinement, and high reliability. Micro-sized electronic packaging metal covers not only have high requirements for plating, but also gradually strengthen the requirements for the appearance of the product in subsequent process applications. At present, the process flow of most electronic packaging metal covers is stamping processing → surface ball milling → surface cleaning and drying → surface acid activation → electrolytic nickel plating or chemical nickel plating → surface cleaning and drying → manual or equipment inspection → qualified products. In the production process of electronic packaging metal covers, because each process has high requirements for the appearance after surface treatment, the frequency of product cleaning and drying processes is relatively high.
[0003] Conventional drying methods for electronic packaging metal covers include box drying and chain furnace drying. In chain furnace drying, specifically, the product to be dried is placed and thinly spread on a stainless steel tray as a carrier tray, and is sent into the equipment together with the stainless steel tray for drying. Since the products to be dried of the electronic packaging metal cover are small in size and thin in structure, with a thickness of only 0.05mm-0.06mm, a smooth surface and light weight, the water molecules between the products have great interaction force and adhesion strength after washing. In addition, when the products to be dried are thinly spread in a stainless steel tray for drying, the products are in close contact with the stainless steel tray without any gap, and there is a pressure difference between the air pressures on the two surfaces of the products. As a result, after drying, not only are the products easy to stick to the bottom of the stainless steel tray, making it difficult to pour out, but the products are also easy to stick to each other and form stacking, which wastes products and brings great difficulties to subsequent inspection work, greatly increasing the inspection labor intensity. Moreover, during the drying process, the products placed in the stainless steel tray are in close contact with the stainless steel tray without any gap, and the spatial fluidity of the bottom surface of the product and the side surfaces of the adjacent products is poor, which is not conducive to water evaporation, which not only affects the drying uniformity and drying effect, but also easily leaves water stains, color block pollution and other appearance quality problems on these parts. Utility Model Content
[0004] The utility model aims to provide a drying material tray in the production process of electronic packaging metal cover plates.
[0005] The technical solution to achieve the purpose of the utility model is: a drying material tray in the production process of electronic packaging metal cover plates, including a loading tray and an isolation net, the loading tray including a tray bottom, a tray body located around the tray bottom and standing upward, and a tray edge formed by folding the tray body outward, the isolation net is spread on the loading tray, and the isolation net is fixed to the tray edge of the loading tray by several rivets on all sides, the isolation net is concave to form a groove structure, and there is a gap between the isolation net and the tray bottom of the loading tray.
[0006] Furthermore, the isolation net is spread over the loading tray. Under this configuration, the usable surface of the isolation net, that is, the area that can be used to place products, is larger.
[0007] Furthermore, the isolation net is wrapped around the edge of the tray. This arrangement can store the edge of the isolation net below the edge of the tray, making the isolation net on the loading tray more tidy.
[0008] Furthermore, each of the rivets passes through the edge of the plate and is wrapped outside the edge of the plate to form the isolation net in an upper and lower folded relationship. After the rivets pass through the isolation net in an upper and lower folded relationship, the isolation net can be fixed more firmly and reliably on the one hand; on the other hand, the edge material of the isolation net collected under the edge of the plate can be prevented from running out, thereby improving the assembly quality of the isolation net and the loading plate.
[0009] Furthermore, a plurality of the rivets are evenly distributed on the plate edges on both sides of the loading plate.
[0010] Furthermore, the mesh size of the isolation net is 80-120 meshes.
[0011] The drying material tray in the production process of the electronic packaging metal cover of the utility model spreads the isolation net on the loading tray, so that when the electronic packaging metal cover product is loaded to dry the electronic packaging metal cover product, the electronic packaging metal cover product can be laid on the isolation net. There is a gap between the electronic packaging metal cover product laid on the isolation net and the bottom of the tray, and the electronic packaging metal cover product has large gas flowability on the upper and lower sides. The greater gas fluidity on both sides of the electronic packaging metal cover products, on the one hand, is conducive to the evaporation of water, so that the electronic packaging metal cover products can be dried quickly, greatly improving the drying rate. At the same time, the water stains on the surface of the quickly dried electronic packaging metal cover products will not penetrate into the interior of the electronic packaging metal cover products due to long-term residence, leaving water stain marks, or penetrate into different color areas in the electronic packaging metal cover products, causing color block pollution. In other words, it can not only greatly increase the drying rate, but also effectively avoid appearance quality problems such as water stain marks and color block pollution. On the other hand, the gas fluidity also makes the air pressure on both sides of the electronic packaging metal cover products consistent, and there is no pressure difference. In addition, the contact area between the electronic packaging metal cover products and the isolation net is small, which makes the dried electronic packaging metal cover products not easy to adhere, easy to pour out, and convenient to dry.
