Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel lamination, and particularly to a pressing plate lamination mechanism and a working method thereof. Background Art

[0002] In the prior art, the lamination of photovoltaic panels can be achieved through pressing plates. The pressing plates are generally driven to lift by driving mechanisms such as cylinders. However, this driving method has the following defects: (1) It is difficult to adjust the pressure, and it is easy to cause the downward pressure to be too large or too small; (2) The pressure is uneven, which is mainly caused by the fact that the pressure at the connection position of the cylinder is greater than that at other positions. Summary of the Invention

[0003] In order to solve the problem of uneven pressure when the cylinder drives the pressing plate to laminate the photovoltaic panel in the prior art, the present invention provides a pressing plate lamination mechanism and a working method for improving the lamination pressure distribution.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: A pressing plate lamination mechanism includes: A lamination heating plate; An upper box, a sealed cavity is formed between the upper box and the lamination heating plate, An inner pressing plate, the inner pressing plate is located in the sealed cavity, and is hermetically connected between the inner pressing plate and the lamination heating plate, dividing the sealed cavity into an upper chamber cavity close to the lamination heating plate and a lower chamber cavity close to the lamination heating plate; A lifting drive mechanism, the lifting drive mechanism is connected to the inner pressing plate and is used to drive its lifting; A disconnection mechanism, the disconnection mechanism can disconnect the driving force of the lifting drive mechanism on the inner pressing plate; A vacuum pumping device, the vacuum pumping device is connected to the lower chamber cavity and is used to achieve vacuum pumping of the lower chamber cavity; A gas channel, the gas channel is arranged on the upper box and is used to communicate the upper chamber cavity with the external air.

[0005] Further, the lifting drive mechanism includes a cylinder installed in the upper box, and the telescopic end of the cylinder is fixedly connected to the inner pressing plate.

[0006] Further, the disconnection mechanism includes a ventilation pipeline communicating with the atmosphere connected to the rodless cavity and the rod cavity of the cylinder and a ventilation valve arranged on the exhaust pipeline.

[0007] Further, a flexible buffer layer is arranged on the lower side of the inner pressing plate.

[0008] Further, a high-temperature cloth isolation layer is arranged on the lower side of the flexible buffer layer.

[0009] Further, a first flexible sealing member for sealing connection with the lamination heating plate is installed at the bottom end of the upper box.

[0010] Further, a second flexible sealing member for sealing connection with the lamination heating plate is installed at the bottom end of the inner pressing plate.

[0011] Further, the first flexible sealing member includes a first sealing rubber ring.

[0012] Further, the second flexible sealing member includes a second sealing rubber ring.

[0013] A working method of a pressing plate lamination mechanism as described above includes the following steps: S1: Place the component to be pressed above the lamination heating plate, seal the connection between the upper box and the lamination heating plate, and make the first sealing rubber ring in close contact with the lamination heating plate; S2: The air cylinder drives the inner pressing plate to descend, and the second sealing rubber ring contacts the lamination heating plate; S3: Evacuate the lower chamber cavity; S4: Open the air vent valve, and both the rod chamber and the rodless chamber of the air cylinder are communicated with the atmosphere, so that the piston rod can move freely; S5: Air enters the upper chamber cavity from the gas passage, the atmospheric pressure acts on the upper side of the inner pressing plate, the vacuum suction acts on the lower side of the inner pressing plate, and the resultant force of the atmospheric pressure and the vacuum suction realizes the downward pressure of the inner pressing plate and acts on the component to be pressed. Beneficial effects

[0014] In the present invention, the atmospheric pressure is added on the basis of the pressing plate lamination to act on the component to be pressed. The atmospheric pressure replaces the driving mechanism to apply a downward pressure to the inner pressing plate, which can ensure the uniform pressure of the pressing plate and improve the lamination effect; The pressing plate main body is a rigid component, and a flexible buffer layer and a high-temperature cloth interlayer are arranged at the position in contact with the component to be pressed, with high overall structural strength and long service life; The pressure relief of the air cylinder is realized through the air pipe line and the air vent valve, with low cost and easy implementation; The upper end of the inner pressing plate bears the atmospheric pressure, and the lower end bears the vacuum suction, with uniform stress on both the upper and lower sides. Therefore, a uniform pressure can be applied to the component to be pressed, while ensuring the required lamination pressure magnitude. Description of the drawings

In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. These terms are only for the convenience of describing the present invention and simplifying the description.
