TECHNICAL FIELD

[0001] The present application belongs to the technical field of photovoltaic laminating machine, and particularly relates to a hot-plate laminating machine and a dismounting and fixing device of a heating plate. BACKGROUND

[0002] In the prior art, the heating element of the hot-plate laminating machine for the photovoltaic module is an electric heating plate (referred to as a heating plate), which has the characteristics of good heating uniformity, environmental protection and easy temperature control, and gradually becomes the mainstream model of the single-layer laminating machine. The main structure of the single-layer laminating machine is that the heating plate is fixedly arranged below the laminating workbench, and the laminating workbench is heated by the heating plate to realize heating of the photovoltaic module. At present, the heating plate is fixedly connected to the laminating workbench by a connecting and fixing member such as a bolt. Connection holes are arranged on the laminating workbench and the heating plate, and the bolt is connected to the laminating workbench and the heating plate by penetrating the connection holes. The bolt is arranged perpendicularly to the laminating workbench. When the heating plate is replaced, the operator needs to enter the laminating machine frame to operate below the laminating workbench, dismount the bolts one by one, replace the new heating plate, and then install the dismounted bolts back one by one to fix the heating plate below the laminating workbench. However, when the hot-plate laminating machine is used in a multi-layer laminating machine, an obstacle is encountered. At present, the structure of the multi-layer laminating machine includes two or more laminating main machines, and each laminating main machine is arranged oppositely. Each laminating main machine includes a laminating workbench. The laminating workbench of each laminating main machine is both the laminating workbench of the upper laminating main machine and the upper cover of the lower laminating main machine.

[0022] The application provides a heating sheet dismounting device and a laminating machine with novel structure, reduces the space occupied during dismounting of the heating sheet, and enables the heating sheet to be applied to a multi-layer laminating machine.

[0023] The laminating machine comprises a laminating main machine, and the laminating main machine comprises an upper box structure 105 with laminating components, a laminating workbench 101 and a heating sheet 102.

[0024] The heating sheet dismounting device of the laminating machine with the structure of the embodiment of the application is as shown in Figures 1-3As shown, the heating sheet dismounting device 201 comprises a flat car composed of a car body 2011 and wheels 2012, a flat car lifting device and a longitudinal pressing device. The flat car body is arranged along the transverse direction of the laminating machine frame. The top of the flat car body constitutes a support plane for supporting the heating sheet. The flat car lifting device is arranged on one side of the laminating machine frame, and the longitudinal pressing device is arranged on the other side of the laminating machine frame, respectively on the left and right sides of the flat car body. The flat car lifting device comprises a slope 2013, which is inclined upward from the flat car to the frame. The length and height of the slope should satisfy that the heating sheet can be attached to the lower surface of the laminating workbench when the flat car climbs along the slope. The longitudinal pressing device 202 comprises a pressing screw 2021 and a pressing frame 2022. The pressing screw is threadedly connected with the pressing frame. The axis of the pressing screw is parallel to the support plane, i.e. the top surface of the flat car body, and opposite to the slope, so as to prevent the flat car from sliding off the slope. The pressing frame is fixedly arranged on the outside of the flat car body and has a height equivalent to that of the flat car body. In order to improve the stability of the flat car, a leveling device is further arranged to adjust the height of the front and rear of the flat car, so that the front and rear of the flat car are closely attached to the lower surface of the laminating workbench. The leveling device comprises a leveling screw 2015 and a leveling frame 2016. The axis of the leveling screw is perpendicular to the support plane. The adjusting screw is threadedly connected with the leveling frame. The leveling screw is located below the flat car body and supports the flat car body through the leveling screw. When mounting the heating sheet, the pressing screw and the leveling screw are adjusted, the flat car is located at the low position of the slope, the heating sheet is inserted between the laminating workbench and the top of the flat car body, the heating sheet is located on the top of the flat car body, the flat car is pushed towards the slope, the front wheel of the flat car walks on the slope, the flat car body is lifted until the flat car cannot be pushed, which proves that the heating sheet has been attached to the lower surface of the laminating workbench. The height of the flat car body is kept parallel to the lower surface of the laminating workbench. The leveling screw is adjusted to press against the flat car body, so that the other end of the flat car body is attached to the lower surface of the laminating workbench. The pressing screw is further adjusted to position the flat car body in the longitudinal direction and prevent the flat car body from sliding along the slope. The heating sheet is fixedly arranged below the laminating workbench. When dismounting the heating sheet, the pressing screw and the leveling screw are loosened, the flat car body falls from the slope, the heating sheet is separated from the lower surface of the laminating workbench, and the heating sheet falls away from the laminating workbench along with the falling of the flat car body.

That is, the laminating workbench of the upper laminating main machine is spaced apart from the upper box structure of the lower laminating main machine, and the upper box structure 105 and the laminating workbench 101 are respectively supported by the frame 104. The heating sheet is located below the laminating workbench, and the clamping frame of the clamping device, the leveling frame of the leveling device, and the slope structure are respectively fixedly arranged above the top of the upper box. By pushing the trolley to slide on the slope, the trolley support plane is moved away from or close to the lower surface of the laminating workbench, thereby supporting and achieving the trolley clamping the electric heating sheet and the laminating machine workbench firmly, and the trolley is fixedly clamped by the leveling device and the longitudinal clamping device. By loosening the clamping screw and the leveling screw, the electric heating sheet can be quickly replaced, avoiding the replacement and dismounting of a large number of parts, occupying a small space, and greatly reducing the distance between the laminating workbench and the upper box structure relative to the space required for personnel access.

[0027] The upper box structure is connected with and supported by the frame, and has an upper cover and / or a pressing component. In each intermediate layer, the upper box structure and the laminating workbench located above it form a whole, and when the laminating machine is closed, the upper box structure and the laminating workbench located below it form a sealed cavity, and the photovoltaic module is laminated by the pressing component in the sealed cavity. In the present application, the upper box structure can adopt the following structure, for example, the upper box structure includes a laminating plate, and a pressing frame is arranged below the laminating plate. When the upper box structure and the laminating workbench are closed, the laminating plate, the pressing frame, and the laminating workbench form a sealed space, and the laminating machine adopting the above-mentioned upper box structure is called a plate pressing type laminating machine in the prior art. The upper box structure can also include an upper cover, and a silica gel plate is arranged below the upper cover. The silica gel plate is fixedly arranged below the upper cover by a clamp, and forms a sealed cavity with the lower part of the upper cover. When the upper cover and the laminating workbench are closed, the upper cover and the laminating workbench form a sealed chamber, and the sealed chamber is divided into an upper cavity and a lower cavity by the silica gel plate. The laminating machine adopting this structure is called a silica gel plate type laminating machine in the prior art.
