Description

Technical Field

[0001] The present invention relates to the technical field of laminators, and more particularly to an airbag contact laminator and a single-layer double-cavity laminator and system composed thereof. Background Art

[0002] Solar cell module laminator is one of the important equipments required for encapsulating solar cell modules. During the production process of solar cell modules, a laminator is needed to press the adhesive film, solar cell sheet, tempered glass and back film into a whole with certain rigidity under high temperature and vacuum conditions.

[0003] However, the current laminators mainly have the following technical problems:

[0004] 1) Currently, all laminating machines use silicone plates for lamination operations. For example, the patent with the authorization announcement number CN114834138B and the patent name is a fully automatic stacking multi-layer laminating machine, which discloses two laminating components (upper box and lower box) adjacent to each other. When pressed together, a first vacuum chamber and a second vacuum chamber separated by silicone plates are formed between the two. On the one hand, the lamination action is performed by two laminating components (upper box and lower box) with the same structure, which has many parts and a complex structure; on the other hand, the silicone plate moves downward and stretches during the vacuuming and inflation process, which is easy to be damaged and needs to be frequently replaced, repaired and replaced, which increases the cost.

[0005] 2) Currently, most laminators are single-chamber laminators, and a single chamber is used to laminate one solar panel. On the one hand, once a single chamber is damaged, it will lead to production interruption, low efficiency and low reliability; on the other hand, it is only laminated once, so the quality is low.

[0006] Therefore, providing a simple, reliable and efficient airbag contact laminator and a single-layer double-cavity laminator and system composed thereof is an issue that needs to be urgently solved by those skilled in the art. Summary of the invention

[0007] In view of this, the present invention provides an airbag contact laminator and a single-layer double-cavity laminator and system composed thereof to solve at least one of the technical problems mentioned in the above background technology part.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] An airbag contact laminating machine comprises a frame, an airbag heating and pressing device, a plurality of hydraulic cylinders, a lower heating plate, and a vacuuming and inflation system. The airbag heating and pressing device is installed on the frame through a plurality of hydraulic cylinders on its periphery; the lower heating plate is horizontally fixed on a supporting frame of the frame and corresponds to the position of the airbag heating and pressing device above it, so that a vacuum laminating chamber is formed when the airbag heating and pressing device is pressed against the lower heating plate; the vacuuming and inflation system is connected to and communicated with the airbag heating and pressing device, and communicated with the vacuum laminating chamber through the lower heating plate.

[0010] By adopting the above technical solution, the beneficial effects of the present invention are:

That is, only one vacuum lamination chamber is used to achieve the lamination of solar cell modules, eliminating the upper box structure and the silicone plate, simplifying the structure, and avoiding frequent replacement and maintenance of the silicone plate, saving costs and improving work efficiency.

[0012] Furthermore, the airbag-type heating and pressing device includes a side frame, an upper heating plate, multiple airbags, an aluminum plate and a silicone pad. The cylinder body of each hydraulic cylinder is vertically mounted on the frame, and the telescopic rod of each hydraulic cylinder is fixedly connected to the side frame through a connecting frame. When the bottom end of the side frame is pressed against the lower heating plate, the vacuum lamination chamber is formed inside the side frame; the upper heating plate is located on the top of the side frame and is connected by a fastening assembly; the tops of multiple airbags are fixedly connected to the upper heating plate and are evenly distributed, and the vacuum extraction and inflation system is connected to the multiple airbags; the aluminum plate is installed at the bottom ends of the multiple airbags; and the silicone pad is laid on the bottom of the aluminum plate.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that when the bottom end of the side frame is pressed against the lower heating plate, the lower heating plate and the upper heating plate begin to heat up, and then when the vacuum and inflation system begins to inflate the inside of the airbag, the compressed air will give pressure to the airbag, forcing it to drive the aluminum plate and the silicone pad to move downward until they are close to the solar cell module for lamination operation.

[0014] Furthermore, the top end and the bottom end of the side frame are both provided with sealing grooves, and sealing rings are installed in the two sealing grooves.

[0017] The beneficial effect of adopting the above-mentioned further technical scheme is that, when the first solenoid valve is opened, the vacuum pump performs a vacuum operation on the vacuum lamination chamber via the vacuum connecting pipeline and the first vacuum pipeline; when the second solenoid valve and the third solenoid valve are opened, the vacuum pump performs a vacuum operation on each airbag via the vacuum connecting pipeline, the second vacuum pipeline, the bellows and the vacuum inflation pipeline; when the second solenoid valve is closed and the third solenoid valve is opened, the compressed air system fills each airbag with compressed gas via the second vacuum pipeline, the bellows and the vacuum inflation pipeline, thereby realizing the integration of vacuuming and inflation pipelines.

[0018] Furthermore, the upper heating plate includes three upper heating plate units, and the three upper heating plate units are arranged in sequence along the top of the side frame; accordingly, the aluminum plate includes three aluminum plate units, and the three aluminum plate units are respectively installed on the bottom of multiple airbags on the three upper heating plate units; the silicone pad includes three silicone pad units, and the three silicone pad units are respectively laid and fixed on the bottom of the three aluminum plate units; the vacuum inflation pipeline includes three vacuum inflation pipeline units and a total input pipeline, and the top end of the corrugated expansion tube is respectively connected to the three vacuum inflation pipeline units through the total input pipeline, and the third solenoid valve is installed on each of the vacuum inflation pipeline units.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that the lamination area is divided into three zones, and multiple solar panels can be laminated at the same time to improve efficiency. If a certain airbag is damaged, lamination can continue at other positions to improve reliability. In addition, users can choose the lamination area and the number of component laminations according to their own situation to improve applicability.

[0020] Furthermore, the upper heating plate and the lower heating plate are electrically connected to an electromagnetic heating control cabinet located outside the rack through a plurality of heat wires.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the electromagnetic heating component is externally placed, which is convenient for its repair and maintenance, avoiding the need to disassemble the heating plate and perform maintenance operations inside the frame.

[0022] An airbag contact single-layer double-cavity laminator comprises a conveying mechanism and two airbag contact laminators as described above, wherein the two airbag contact laminators are arranged in sequence from left to right and are aligned; the conveying mechanism is installed on the frames of the two airbag contact laminators to form a conveying channel between the side frame and the lower heating plate.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:
