Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic component lamination, and in particular to a double-glass photovoltaic component continuous lamination device. Background Art

[0002] Double-glass photovoltaic modules are an advanced solar panel design that consists of two pieces of glass sandwiching solar cells. This design not only significantly enhances the mechanical strength of the module, enabling it to withstand external forces such as snow pressure and trampling, but also reduces the deformation and micro-cracks of the solar cells. Double-glass photovoltaic modules also have a double-sided power generation function. The incident light energy on the back is absorbed and converted into electrical energy, increasing the light-receiving area of ​​the cell, thereby obtaining a higher power generation gain.

[0003] When manufacturing double-glass photovoltaic modules, lamination is a key manufacturing step, which involves laminating solar cells, packaging materials and two pieces of glass together to form a complete and durable photovoltaic module. Chinese invention patent CN108437601A discloses a double-sided double-glass photovoltaic module continuous lamination device, which places the photovoltaic module on the mounting seat through a series of automated process operations, and then drives the transmission roller of the transmission mechanism through the first drive mechanism, and uses the driving teeth on the transmission roller to cooperate with the driving teeth on the mounting seat to drive the mounting seat to move in the transmission channel. When the mounting seat reaches the bottom of the pressure mechanism, the second drive mechanism will drive the pressure mechanism to descend and accurately laminate the photovoltaic module.

[0004] However, despite the innovation of the equipment in automated lamination, there are some limitations in practical application. First, before use, the various material layers of the photovoltaic modules need to be manually stacked neatly in advance, and this step cannot be fully automated. Secondly, after the lamination is completed, the photovoltaic modules in the mounting base need to be manually removed before the next round of lamination can be started. The manual intervention in this process has led to a decrease in the overall lamination efficiency. Especially in the pursuit of high-efficiency assembly line production, this incoherent operation process has become a bottleneck for improving productivity. Summary of the invention

[0005] In order to overcome the above-mentioned disadvantage of the discontinuous lamination process in the prior art, the present invention provides a double-glass photovoltaic module continuous lamination device.

[0011] As a preferred technical solution of the present invention, a guide ring frame is also provided in the middle of the base, and a card-embedded guide plate is fixedly provided at the bottom of the lamination frame. The lower part of the card-embedded guide plate is embedded in the annular groove of the guide ring frame, and the card-embedded guide plate can slide in the annular groove of the guide ring frame.

[0012] As a preferred technical solution of the present invention, the guide ring frame is divided into a fixed part and a movable part.

[0013] As a preferred technical solution of the present invention, a cylinder is installed on the base directly below the movable part of the guide ring frame, and the movable end of the cylinder is fixedly connected to the movable part of the guide ring frame. The extension or contraction of the movable end of the cylinder will pull the movable part and the embedded guide plate on the movable part to rise and fall synchronously with the laminating frame.

[0014] As a preferred technical solution of the present invention, right-angle connecting rods are slidably arranged on the front and rear sides of the discharge transmission frame, and a wedge block is fixedly connected to the lower part of the two right-angle connecting rods. The top of the wedge block is arranged as an inclined surface inclined toward the discharge transmission frame.
