Technical Field
[0001] This utility model relates to the field of photovoltaic module lamination and encapsulation technology, and more specifically to a cooling platform-type electro-injection device. Background Technology
[0002] With the continuous growth of global demand for clean energy, the photovoltaic industry has developed rapidly, and the production technology of photovoltaic modules has also been continuously improving. However, with the intensification of market competition, the price of photovoltaic modules has been declining, making it crucial for companies to improve module power and conversion efficiency to enhance their competitiveness.
[0003] In the production of photovoltaic modules, defect repair of solar cells is a crucial step affecting module power. During production, solar cells may experience power loss due to various reasons (such as material impurities, crystal defects, and process inhomogeneities). In traditional processes, electro-injection is typically performed only during the cell manufacturing stage, lacking a dedicated electro-injection process at the encapsulation end, making direct injection repair of the module impossible. This limitation means that defects generated in the front-end processes of the solar module cannot be perfectly repaired, thus affecting the overall power and performance of the module.
[0004] Furthermore, in existing technologies, the primary function of a photovoltaic module cooling platform is to rapidly cool the module from a high temperature to room temperature for subsequent encapsulation processes. However, traditional cooling platforms only provide cooling and cannot perform further optimization treatments on the module during the cooling process. This single-function design limits the improvement of module performance, especially in repairing internal defects in the cells. Therefore, existing cooling platforms cannot meet the demands for increased photovoltaic module power, particularly on high-efficiency, high-capacity production lines, where a device capable of enabling electrical injection on the cooling platform is lacking.
[0005] On the other hand, the structural design of traditional cooling platforms also has some problems. For example, the maintenance and upkeep of cooling platforms are usually quite complex, requiring downtime for operation, which not only affects production efficiency but may also increase equipment wear and tear and failure rate. In addition, existing cooling platforms cannot achieve precise monitoring and control of component temperature, which makes it impossible to accurately perform electro-injection operations during the cooling process, further limiting the improvement of component performance.
[0006] In summary, existing technologies lack a device capable of performing efficient and precise electro-injection operations during the photovoltaic module encapsulation process, particularly on the laminator cooling platform. Existing cooling platform structures cannot repair internal defects in the module during cooling and cannot effectively improve module power output. Furthermore, the design of traditional cooling platforms is not conducive to equipment maintenance and upkeep.
[0007] Therefore, there is an urgent need for a device that can realize the function of electrical injection on the cooling platform to meet the demand for increased photovoltaic module power, without affecting the production capacity of the equipment, and is easy to maintain and repair. Utility Model Content
[0008] In view of this, the present invention provides a cooling platform type electric injection device, which aims to solve the above-mentioned technical problems.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A cooling platform type electro-injection device, comprising:
[0011] X-axis main mounting rail, on which an X-axis main mounting bracket is connected via an X-axis positioning slider;
[0012] The Y-axis main mounting rail is fixed on the X-axis main mounting frame, and the Y-axis main mounting rail is connected to a mounting plate via a Y-axis positioning slider;
[0013] A Y-axis linear drive module is mounted on the mounting plate.
[0014] An X-axis linear drive module is mounted on the Y-axis drive slide of the Y-axis linear drive module.
[0015] An electrical injection mechanism is provided, wherein the mounting end of the electrical injection mechanism is connected to the X-direction drive slide of the X-direction linear drive module, and is used to realize the electrical connection between the probe of the electrical injection mechanism and the component lead wire.
[0016] Through the above technical solution, this utility model integrates the electro-injection function into the cooling platform, enabling simultaneous electro-injection operations during the module cooling process. This avoids additional processes and equipment, improving production efficiency. The linear drive modules in the X and Y directions achieve precise movement of the electro-injection mechanism in a two-dimensional plane, accurately aligning the probe with the module lead wires and establishing electrical connections, thus improving the accuracy of the electro-injection operation. This device can be flexibly adjusted according to the size and position of different modules, adapting to the production of various photovoltaic module specifications and possessing strong versatility.

The bolted connection ensures a secure connection between the positioning slider and the mounting rail and mounting plate, improving the stability of the device during operation and reducing loosening or displacement caused by vibration or impact. The bolted connection facilitates installation and disassembly, allowing for convenient adjustment or maintenance of the device when needed, such as replacing worn parts or readjusting positioning accuracy. The tight-fitting design enables the device to maintain good working condition during long-term operation, reducing malfunctions caused by loose connections and improving the reliability of the device.
[0018] Preferably, in the aforementioned cooling platform-type electro-injection device, an image acquisition camera is mounted on the bottom surface of the mounting plate. The image acquisition camera can acquire the component's position information in real time, providing precise visual guidance for the movement of the electro-injection mechanism, ensuring that the probe is accurately aligned with the component's lead wire, and improving the success rate of the electro-injection operation. The image information acquired by the camera can be combined with the control system to achieve automated positioning and operation, reducing manual intervention and improving production efficiency and operational accuracy. The camera can also be used to monitor the appearance quality of the components, promptly detecting any defects or abnormalities that may occur during the production process, facilitating timely intervention and improving product quality.
[0019] Preferably, in the aforementioned cooling platform-type electro-injection device, a temperature detection sensor is installed on the bottom surface of the mounting plate.

Through temperature data feedback, process parameters such as the cooling rate and cooling method of the cooling platform can be optimized and adjusted to improve cooling efficiency and component performance. In case of abnormal temperatures, alarms can be issued promptly or measures can be taken to prevent damage to the component due to overheating or overcooling, ensuring the safety of the production process and the quality of the component.

This electro-injection mechanism has a simple design structure, is easy to manufacture and maintain, and enables rapid and accurate movement by driving the probes up and down with cylinders, improving the efficiency of the electro-injection operation. The telescopic movement of the cylinders can be precisely controlled by a control system, allowing adjustment of the probe's downward pressure and stroke as needed, ensuring the stability and reliability of the electro-injection operation. The two cylinders symmetrically fixed at both ends of the transverse guide rail ensure uniform force on the probes during downward pressure, avoiding component damage or uneven electro-injection caused by uneven force, thus improving product quality.
[0021] Preferably, in the above-described cooling platform type electro-injection device, the cylinder is connected to the transverse guide rail via a slide and is secured with bolts. The design of the slide allows the position of the cylinder on the transverse guide rail to be flexibly adjusted as needed, facilitating optimized configuration according to the size and position requirements of different components and improving the adaptability of the device.
