[0002] With the popularity of mobile phones, tablet computers, and various smart wearable devices, in order to meet the diverse needs of users, it is usually necessary to use laminated glass cover plates to increase the aesthetics and quality of electronic devices. A glass cover plate is a type of cover plate made of glass, which needs to be coated during the production process. During the processing of the glass cover plate, it needs to be loaded for processing. In particular, when testing the quality of its surface coating, it is necessary to clamp and position the glass cover plate while ensuring that its coated surface is completely exposed for subsequent testing operations. In addition, glass cover plates come in different sizes. When clamping and positioning small-sized glass cover plates (such as the glass cover plates for the side buttons of mobile phones), there is a risk that the clamping force is too large, which may damage the product, or the force is too small, which may prevent stable positioning.

[0018] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0019] Example 1: A vacuum adsorption carrier for tiny products, comprising: a base 1 and a carrier plate 2 installed on the upper surface of the base 1, wherein the upper surface of the carrier plate 2 is provided with at least two adsorption hole groups corresponding to the products 100 to be loaded, and each of the adsorption hole groups is composed of two adsorption holes 3 spaced apart along the length direction of the product 100 to be loaded, and the lower ends of the adsorption holes 3 whose upper ends are in contact with the product 100 to be loaded are connected to the vacuum channel 4 provided on the base 1, and the shape of the adsorption holes 3 is the same as that of the product 100 to be loaded, and the area ratio between each adsorption hole 3 and the product 100 to be loaded is 1:3.

[0020] The number of the vacuum channels 4 is the same as the number of the adsorption hole groups, and the two adsorption holes 3 in the same adsorption hole group are connected to the same vacuum channel 4. There are 6 adsorption hole groups, which are spaced apart in a direction perpendicular to the length of the product 100 to be loaded.

[0021] Example 2: A vacuum adsorption carrier for tiny products, comprising: a base 1 and a carrier plate 2 mounted on the upper surface of the base 1. The upper surface of the carrier plate 2 is provided with at least two adsorption hole groups corresponding to the products 100 to be loaded. Each adsorption hole group is composed of two adsorption holes 3 spaced apart along the length of the product 100 to be loaded. The lower ends of the adsorption holes 3, whose upper ends contact the product 100 to be loaded, are connected to a vacuum channel 4 provided on the base 1. The shape of the adsorption holes 3 is the same as that of the product 100 to be loaded, and the area ratio between each adsorption hole 3 and the product 100 to be loaded is 1:3.5. There are five such adsorption hole groups, spaced apart in a direction perpendicular to the length of the product 100 to be loaded.

[0022] The above-mentioned vacuum channel 4 further includes: a vacuum groove portion 41 opened on the upper surface of the base 1, a vertical connecting portion 42 whose upper end is connected to the vacuum groove portion 41, and a horizontal connecting portion 43 connected to the lower end of the vertical connecting portion 42, and the end of the horizontal connecting portion 43 opposite to the vertical connecting portion 42 is connected to the air pipe joint 5 installed on the side surface of the base 1.

[0023] The vertically penetrating adsorption hole 3 is communicated with the vacuum groove 41 of the vacuum channel 4 . The shape of the vacuum groove 41 is the same as that of the adsorption hole 3 .

[0024] A sealing ring 6 is provided between the base 1 and the carrier plate 2 and outside each vacuum groove 41 .

[0025] Working principle: When in use, connect the vacuum channel to a vacuum generator or vacuum pump to create negative pressure in the vacuum channel;

[0026] An external transport mechanism, such as a robotic arm or vacuum nozzle, transports the same number of products to be loaded (e.g., the glass cover of a mobile phone's side button) as the number of adsorption hole groups onto the carrier plate, ensuring that each product to be loaded is directly above the corresponding adsorption hole group and that the length direction of the product to be loaded is consistent with the arrangement direction of the two adsorption holes in the adsorption hole group and the length direction of each adsorption hole.

[0027] Through the negative pressure generated in the adsorption hole, one side of the surface of the product to be loaded is adsorbed and positioned, and the other side surface (such as the coating surface) is completely exposed to facilitate the processing of the other side of the product to be loaded;

[0028] Two contoured adsorption holes are arranged at intervals along the length of the product, and the size of the adsorption holes is controlled to match the product. This can prevent air leakage due to excessive adsorption holes, which can lead to insufficient adsorption force, and also avoid damage to the product due to excessive adsorption force, thereby improving the stability of tiny product positioning and the uniformity of product force.

[0029] When using the vacuum adsorption carrier for the above-mentioned tiny products, it can not only avoid the situation where the product is deflected due to insufficient adsorption force during subsequent processing, but also avoid damage to the product due to excessive adsorption force, thereby improving the stability of the positioning of tiny products and the uniformity of the force on the products.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
