Technical Field

[0001] This utility model relates to the field of vacuum adsorption stages, and in particular to a vacuum adsorption stage that effectively adapts to the thermal deformation of the platform. Background Technology

[0002] When a vacuum heating platform made of metal is heated, the product adsorption plate is prone to deformation due to thermal expansion and contraction, resulting in an uneven upper surface. In fields such as slot coating, the flatness requirements for the vacuum adsorption platform on which the product is placed are high, necessitating a reasonable design to accommodate deformation caused by changes in platform temperature.

This application uses elastic connectors to press and connect the base plate, heating plate, and product adsorption plate together, while simultaneously providing the adsorption platform with a certain deformation redundancy after thermal deformation, allowing the adsorption platform to expand as a whole without bending.

The base plate, heating plate, and product adsorption plate are connected together from bottom to top by the elastic connector, and the product adsorption plate has several suction holes distributed on it.

[0006] Specifically, the elastic connector includes a bolt and a spring. Several through holes for threaded rods of the bolt are distributed on both the base plate and the heating plate. The bottom surface of the product adsorption plate is provided with a threaded blind hole. The threaded rod of the bolt passes through the through holes on the base plate and the heating plate and is threaded into the threaded blind hole on the product adsorption plate. A spring is provided between the bolt head and the base plate to press the base plate, the heating plate, and the product adsorption plate together.

[0016] Structural diagram.

[0017] Combined with appendix Figure 1 and attached Figure 2 As shown, a vacuum adsorption stage that effectively adapts to the thermal deformation of a platform includes a base plate 1, a heating plate 2, a product adsorption plate 3, and an elastic connector 4. The base plate 1, the heating plate 2, and the product adsorption plate 3 are connected together from bottom to top by the elastic connector 4. Several suction holes are distributed on the product adsorption plate 3.

[0018] The elastic connector 4 includes a bolt and a spring. Several through holes for threaded rods of the bolt are distributed on the base plate 1 and the heating plate 2. The bottom surface of the product adsorption plate 3 is provided with a threaded blind hole. The threaded rod of the bolt passes through the through holes on the base plate 1 and the heating plate 2 and is threaded into the threaded blind hole on the product adsorption plate 3. A spring is provided between the bolt head and the base plate 1 to press the base plate 1, the heating plate 2, and the product adsorption plate 3 together.

[0019] The base plate 1 is a marble slab.

[0020] Heating plate 2 is a metal plate, and heating rods are installed inside heating plate 2.

[0021] Several elastic connectors 4 are arranged in an array on the vacuum adsorption platform. There is a movable space between the bolt heads of the elastic connectors 4 and the base plate 1, and a spring is installed within this space. The spring can apply a certain pressure to the base plate 1, the heating plate 2, and the product adsorption plate 3, keeping them in a close fit. When the product adsorption plate 3 is heated and undergoes significant deformation, the spring has a certain deformation redundancy, allowing the entire adsorption platform to expand. Furthermore, the product adsorption plate 3 can expand horizontally without arching or bending due to inconsistent expansion or obstructed horizontal expansion.
