Description

Technical Field

[0001] The present invention relates to the technical field of glue coating devices, and in particular to a glue coating and laminating device. Background Art

[0002] Solar panels absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical reaction. Most solar cells use glass back panels and cover panels, which are not easy to bend and inconvenient to carry. Therefore, flexible thin-film solar cells came into being. During the production process, they need to apply glue, apply packaging film, and remove the protective film on the surface of the packaging film. At present, since most of the coating devices are fixed and there is no integrated protective film removal device, in order to stably and evenly apply glue, another coating device needs to be set up to meet the use requirements. Therefore, the setting method of mobile products and fixed coating devices is difficult to meet the use requirements of compact structure, flexible operation, and stable coating quality of the coating equipment.

[0014] The beneficial effects of the present invention are:

[0015] 1. The glue coating device of the present application, by setting the unwinding and coating component and the winding component to be movable, the coating method of the product to be coated is modified from the method of moving product A to force the movement of product B on the unwinding roller to be moved to the method of actively moving product B to adhere to product A. Because both product A and product B are easy to tear and deform, this method of the present application can effectively avoid tearing and deformation, ensure the quality of the coating, and the operation of the present application is flexible and convenient. By integrating the glue coating component on the unwinding and coating component, not only the structure of the whole equipment is compact, but also the glue coating can be automatically and flexibly applied, which effectively reduces the cost of the equipment and reduces the floor space of the equipment, so that the quality of the glue coating can be guaranteed.

[0016] 2. In the glue coating and laminating device of the present application, the provision of the first pressing assembly can further ensure the flatness of the delivered product B before laminating.

[0017] 3. The setting of the winding component of the present application drives the winding roller to wind up through the winding motor, and drives the winding drive roller to carry out quantitative winding through the winding drive motor, so as to cooperate with each other and avoid the increasing diameter of the winding roller caused by the increasing amount of film on the winding roller. When the winding motor rotates at a uniform speed, the angular velocity is constant, and the linear velocity is increasing, resulting in that the film winding speed at the lower end cannot be controlled, causing damage to the product.

[0018] 4. The winding drive roller and the auxiliary pressure roller are used in combination. The structure is simple but widely applicable. It can be adjusted at multiple angles. The design avoids errors in the processed parts that make it impossible to ensure the flatness of the film. It is flexible to use.

[0019] 5. The setting of the pressing block can effectively ensure that the protective film will not be damaged or deformed when it starts to roll up.

[0020] 6. The setting of the flattening component can effectively flatten product A. Since the product is easy to deform, the downward movement of the flattening roller pressing the product through the cam mechanism is more stable and the force is controllable.

[0021] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

The upper and lower sides of the movable pressing roller are respectively abutted by limit screws to limit the rotation of the movable pressing roller.

3. The glue coating device according to claim 2, characterized in that: A clamping block installed on the second substrate is also provided between the coating roller and the first transition wheel. The clamping block can clamp or release the protective film along the Z direction through a clamping cylinder. A buffer assembly is also provided between the clamping block and the first transition wheel. The buffer assembly includes a buffer shaft for the traction end of the protective film to bypass and can slide along the X direction.

4. The glue coating and laminating device according to claim 1, characterized in that: The machine also includes a frame having a mounting table, the workbench is mounted on the mounting table, an electric control box is provided on the lower side of the mounting table, a Y-axis transfer mechanism is also provided on the mounting table, the unwinding and coating assembly and the winding assembly are both mounted on the Y-axis transfer mechanism, and a heating assembly is also provided on the lower side of the workbench for heating the workbench to cure the glue applied on product A.

5. The glue coating device according to claim 4, characterized in that: A flattening assembly is installed on the mounting table and is arranged across the workbench roughly along the width direction of the workbench. The flattening assembly includes a flattening roller arranged across the workbench, which can reciprocate along the X direction to flatten the product A on the workbench. A driving assembly for driving the flattening roller to move along the Z direction is installed at one end of the flattening roller. The driving assembly includes a rotating shaft, and a cam is detachably fixedly installed at one end of the rotating shaft close to the flattening roller. A roller connected to the cam transmission is installed at one end of the flattening roller close to the driving assembly.

6. The glue coating device according to claim 1, characterized in that: The glue coating and film coating device also includes a clamping assembly arranged across the workbench roughly along the width direction of the workbench, and the clamping assembly includes a pressing plate arranged across the workbench, and the pressing plate is used to clamp and fix one end of the product A placed on the workbench, and it can approach or move away from the workbench surface along the Z direction to clamp or release the end of the product A.

7. The glue coating and laminating device according to claim 4, characterized in that: A control device is installed in the electric control box, and the control device controls the unwinding and laminating assembly, the gluing assembly and the winding assembly.
