Pressing device

Abstract

This invention provides a pressing device. The pressing device includes a fixed frame, a base, and a pressing module. The base is disposed in the hollow portion of the fixed frame and is supported by a bearing plate. The pressing module is disposed in the hollow portion and includes a fixed plate, an inflatable structure, a pressing plate, and a lifting module. The fixed plate is disposed on the fixed frame. The inflatable structure includes an air bladder and an inflation unit. The inflation unit is connected to the air bladder. The pressing plate is disposed on the inflatable structure and faces the base. The lifting module is disposed between the pressing plate and the fixed frame and supports the pressing plate. When the inflation unit inflates the air bladder, it pushes the pressing plate downward and causes the pressing plate to press against the base plate. When the inflation unit deflates the air bladder, it causes the pressing plate to rise and separate from the base plate.

Claims

1. A pressing device, configured to press a plate, comprising: a fixed frame including a fixed frame top plate and a fixed frame bottom plate disposed opposite each other, and a hollow portion formed between the fixed frame top plate and the fixed frame bottom plate; a base disposed on the fixed frame bottom plate, located in the hollow portion, and configured to support the plate; and a pressing module disposed in the hollow portion, comprising: a fixed plate disposed on the fixed frame top plate; an inflatable structure including an airbag and an inflation unit, wherein the airbag is disposed on the fixed plate, wherein the inflation unit is connected to the airbag and configured to inflate or deflate the airbag; a pressing plate disposed on the inflatable structure and facing the base; and a lifting module disposed between the pressing plate and the fixed frame bottom plate, and configured to liftably support the pressing plate; wherein... When the inflation unit inflates the airbag, it pushes the pressing plate and the lifting module downward, and the pressing plate presses down on the plate of the base. When the inflation unit deflates the airbag, it causes the pressing plate and the lifting module to rise and move upward, and the pressing plate separates from the plate.

2. The pressing device as claimed in claim 1, wherein the fixing frame includes at least one fixing frame side plate, wherein the at least one fixing frame side plate is connected between the fixing frame top plate and a fixing frame bottom plate and is disposed around the hollow portion.

3. The compression device as claimed in claim 1, wherein the fixed plate includes a gas channel, wherein the inflation unit of the inflation structure is in fluid communication with the airbag through the gas channel.

4. The compression device as claimed in claim 3, wherein the inflation structure further comprises: a first sensing unit disposed in the airbag and configured to sense the gas pressure inside the airbag and generate a pressure signal; a valve unit fluidly connected to the airbag and the outside of the airbag in an openable and closable manner; and a processing unit communicatively connected to the first sensing unit, the valve unit and the inflation unit, and configured to receive the pressure signal from the first sensing unit, control the inflation unit to inflate the airbag according to the pressure signal, and control the opening and closing of the valve unit.

5. The pressing device as claimed in claim 1, wherein the pressing module further includes a heating unit, wherein the heating unit is embedded in the fixed plate, configured to generate heat energy and conduct the heat energy through the fixed plate, the airbag and the pressing plate to the plate being pressed by the pressing plate.

6. The compression device as claimed in claim 1, wherein the compression module further includes at least one limiting unit, wherein the at least one limiting unit is disposed around the periphery of the airbag, and the at least one limiting unit is configured to restrict the inflation or contraction of the airbag.

7. The pressing device as claimed in claim 1, wherein the pressing module further includes a contact unit disposed on the pressing plate, facing the base, and configured to abut against the plate.

8. The pressing device as claimed in claim 7, wherein the contact unit is a flexible or rigid structure.

9. The pressing device as claimed in claim 1, wherein the lifting module comprises at least one of a spring, at least one motor lifting unit, and at least one cylinder lifting unit.

10. The pressing device as claimed in claim 1, wherein the base comprises: a base top surface disposed facing the pressing module and configured to support the plate; a vacuum channel disposed on the base top surface, wherein the plate covers the vacuum channel to form a closed channel; at least one pressure sensing unit disposed on the base top surface and configured to sense the uniformity of the pressure applied by the pressing plate to the plate; and a suction unit connected to the vacuum channel, configured to adsorb the plate onto the base top surface and suction the gas in the closed channel, thereby creating a negative pressure state in the closed channel.

11. The pressing device as described in claim 1 further includes a plurality of second sensing units disposed on the base or the mounting base plate of the mounting bracket.

12. The pressing device as claimed in claim 1, wherein the base is a heating element for generating heat and conducting it to the plate.
