Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell manufacturing, in particular to a photovoltaic component power injection mechanism. Background Art

[0002] Solar cells and photovoltaic modules will experience power attenuation after being exposed to light. Power attenuation will directly reduce the power generation of photovoltaic modules. When the power attenuation exceeds a certain range, the photovoltaic modules will experience large fluctuations in power generation when the photovoltaic power station is operating. In order to reduce the impact of this phenomenon, the photovoltaic industry is currently adding anti-light decay equipment to the battery manufacturing end to treat the battery with anti-light decay, so that the battery function can be restored and reach a stable state. The injection equipment usually includes multiple injection layers, and the injection layers are provided with injection probes for injection operations. The existing structures of the injection probes are mostly probes for testing electronic products, which have disadvantages such as poor durability and small load current. They cannot meet the requirements of high current and high frequency working conditions. In addition, there are many specifications for photovoltaic modules, which puts higher requirements on the compatibility of injection probes. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Figure 1 The schematic diagram of the structure of the photovoltaic module charging mechanism provided by the embodiment of the utility model. Figure 1 As shown, the embodiment of the utility model provides a photovoltaic assembly power injection mechanism, and the photovoltaic assembly power injection mechanism may include:

[0020] Mounting plate 1;

[0021] Cylinder 2, cylinder 2 is slidably connected to the mounting plate 1;

[0022] A connecting rod 3, which is arranged at the output end of the cylinder 2;

[0023] The injection probe 4 is arranged at the end of the connecting rod 3 .

[0024] The photovoltaic module power injection mechanism provided in the embodiment of the utility model enables the power injection probe 4 to slide in a relatively large range, thereby meeting the power injection operation requirements of photovoltaic modules of different specifications, thereby achieving the purpose of compatibility.

[0025] Figure 2The schematic diagram of the structure of the photovoltaic module charging mechanism provided by the embodiment of the utility model. In one embodiment of the utility model, Figure 2 As shown, the injection probe 4 includes a probe connecting rod 41 and a probe head 42 connected to the bottom of the probe connecting rod 41 . The probe head 42 is a circular structure, and the bottom of the probe head 42 is densely covered with a plurality of spikes.

[0026] The injection probe 4 of the photovoltaic module injection mechanism provided in the embodiment of the utility model adopts a split structure of a probe connecting rod 41 and a probe head 42, which reduces the probe replacement cost compared with the integrated structure; the probe head 42 is designed to be circular to ensure a good contact surface with the bus bar of the photovoltaic module at any angle; the bottom of the probe head 42 is designed to be densely covered with spikes, which can avoid poor contact caused by residual glue impurities on the bus bar to a certain extent; the probe head 42 can use tungsten copper with good conductivity and oxidation resistance as the preparation base material, which can improve the success rate of injection.

[0027] Furthermore, in one embodiment of the present invention, a buffer spring is provided between the probe head 42 and the connecting rod 3. By selecting a suitable spring specification, the magnitude of the pressure under the injection probe 4 can be effectively controlled, which plays a vital role in the injection yield.

[0028] like Figure 1 As shown, in one embodiment of the utility model, a slide rail 5 is provided on the mounting plate 1 of the photovoltaic module injection mechanism, a slider 6 is slidably connected to the slide rail 5, a connecting plate 7 is provided on the slider 6, and the cylinder 2 is installed on the connecting plate 7. Through the cooperation between the slide rail 5 and the slider 6, the injection probe 4 can slide at any position on the slide rail, thereby achieving the purpose of compatibility.

[0029] like Figure 1 As shown, the connecting plate 7 has multiple groups of mounting holes. The cylinder 2 can be installed in different mounting holes, thereby ensuring that the entire charging mechanism can adapt to the charging requirements of the production of multiple specifications of products.

[0030] In the specific application process, the working principle of the photovoltaic module charging mechanism provided by the utility model is as follows:

[0031] During operation, when performing injection operations on photovoltaic modules of different specifications, the cylinder 2 can be installed on a suitable mounting hole, and through the cooperation of the slide rail 5 and the slider 6, the injection probe 4 can slide at any position on the slide rail to adapt to the injection requirements of the production of products of multiple specifications; the output end of the cylinder 2 drives the connecting rod 3 and the injection probe 4 to be pressed down to the bus bar of the photovoltaic module and complete the injection operation. During the pressing process, the buffer spring between the probe head 42 and the connecting rod 3 controls the size of the downward pressure of the injection probe 4, thereby effectively improving the injection yield.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
