Description

Technical Field

[0001] This utility model belongs to the technical field of film adsorption equipment, and in particular relates to a vacuum adsorption platform for FPC adhesive materials. Background Technology

[0002] A vacuum adsorption stage is a commonly used workpiece support device. It is used in fields such as circuit board manufacturing, liquid crystal display panel manufacturing, semiconductor processing, and optical thin film manufacturing to support and position workpieces for various processing. Existing vacuum adsorption stages typically include a vacuum source, which includes a vacuum chamber connected to a vacuum pump via a vacuum pump interface. The vacuum chamber is open at the top and covered with a support mesh. A support plate with multiple adsorption holes is located on the support mesh and positioned by positioning structures such as positioning pins. The workpiece to be processed is placed on the support plate. When the vacuum pump starts to evacuate, the workpiece is adsorbed and positioned by the adsorption holes of the support plate.

[0003] Because the support plate is under vacuum and atmospheric pressure on both sides during adsorption, resulting in a significant pressure difference, the support plate must be made of a material with high hardness and strength to prevent bending and deformation. However, some workpieces have low surface hardness (for example, the hardness of the solder resist layer on a circuit board is only about 2H before and 4H after exposure), or some workpieces have easily damaged optical films on their surfaces. Furthermore, the force between the workpiece and the support plate is relatively large (due to the vacuum adsorption force). Therefore, when a vacuum adsorption stage is used to support such workpieces, the relatively hard support plate can easily cause surface defects such as adsorption marks on the workpiece surface. Moreover, existing technologies make it inconvenient to remove the product after vacuum adsorption. Utility Model Content
