Description

Technical Field

[0001] The utility model relates to the technical field of solar cell chips, in particular to a solar cell chip detection device. Background Art

[0002] Solar cells are divided into crystalline silicon and amorphous silicon. Crystalline silicon cells can be divided into single crystal cells and polycrystalline cells. The efficiency of single crystal silicon is also different from that of polycrystalline silicon. Solar cells use a co-firing process that only requires one sintering to form ohmic contacts between the upper and lower electrodes. The silicon wafers printed with silver paste, silver aluminum paste, and aluminum paste are dried to completely volatilize the organic solvent, and the film layer shrinks to become a solid and adheres tightly to the silicon wafer. At this time, it can be regarded as the metal electrode material layer and the silicon wafer are in contact with each other. When the electrode metal material and semiconductor single crystal silicon are heated to the eutectic temperature, the single crystal silicon atoms are dissolved in the molten alloy electrode material in a certain proportion. The whole process of single crystal silicon atoms dissolving into the electrode metal is quite fast, generally only a few seconds. In the process of the production process of solar cells, certain detection devices are also required for detection.

[0003] According to the announcement number: CN208076413U, a detection device for solar cell sheets is disclosed, including a base and a height adjuster, the height adjuster is installed and fixed at the middle position of the upper end of the base, and the threaded fixed legs composed of threaded columns, support blocks and fixed suction cups are more secure when fixed and placed, and the threaded fixed legs can be rotatably fixed to the lower end of the base through the threaded columns, and the support blocks of the threaded fixed legs can play a good supporting role, and the fixed suction cups at the lower end of the support blocks can be well fixed to the object through the pressure difference between the inside and outside atmospheric pressures. The placement table composed of a long board, a telescopic rod, a welding block and a platform can change the size of the placement area according to the length of the detected object, and the placement table is welded and fixed to the lower column block of the height adjuster through the welding block, which is more convenient to use.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the existing solar cell detection device is not very firm when fixed and is easily tilted due to shaking, the existing solar cell detection device placement table cannot change the placement size well, so that when performing detection, it is easy to be difficult to detect because the solar cell is too long.

[0005] However, in actual use, when the solar cell is placed on the working board for inspection, since there is no limiting structure for the solar cell, when the solar cell is subjected to external force, it is easy to shake or fall, thereby affecting the normal inspection of the solar cell. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a solar cell detection device, which has the advantage of auxiliary limit, and solves the problem that when the solar cell is placed on a working plate for detection, since there is no limit structure set for the solar cell, when the solar cell is subjected to external force, it is easy to shake or fall, thereby affecting the normal detection of the solar cell.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solar cell detection device, comprising a base, a working plate, a detection device body and a detection head, wherein the working plate is fixedly connected to the front side of the base, the detection device body is fixedly installed on the rear side of the top of the base, the detection head is fixedly installed on the front side of the bottom of the detection device body, the rear side of the top of the working plate is fixedly connected to a reference plate, the front side of the top of the working plate is provided with a clamping plate, the right side of the clamping plate is fixedly connected to a transmission mechanism, and the left side of the clamping plate is fixedly connected to a limiting component.

[0009] As a preferred embodiment of the present invention, the limiting assembly includes a limiting plate, the limiting plate is fixedly connected to the left side of the clamping plate, and the interior of the limiting plate is slidably connected to the limiting rod via a through hole.

[0010] As a preferred embodiment of the utility model, the rotating support assembly includes a bearing, the bearing is movably connected to the front and rear sides of the screw rod surface, the surface of the bearing is movably connected to a support plate, and the bottom of the support plate is fixedly connected to the base.

[0011] As a preferred embodiment of the present invention, the front end and the rear end of the limit rod are fixedly connected to a support block, and the bottom of the support block is fixedly connected to the base.

[0012] As a preferred embodiment of the present invention, a protective pad is pasted on the back side of the clamping plate and the front side of the reference plate, and the material of the protective pad is natural rubber.

[0013] As a preferred embodiment of the present invention, a connecting rod is fixedly connected to the right side of the limiting plate, and the other end of the connecting rod is fixedly connected to the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a reference plate, a clamping plate, a transmission mechanism and a limit assembly. When in use, the operator places the solar cell on the top of the working plate and fits one side of the solar cell with the reference plate. Then the transmission mechanism drives the clamping plate to clamp the solar cell through the limit assembly to prevent the solar cell from shaking or falling due to external force, thereby ensuring the stability of solar cell detection. It solves the problem that when the solar cell is placed on the working plate for detection, because there is no limit structure provided for the solar cell, the solar cell is prone to shaking or falling when subjected to external force, thereby affecting the normal detection of the solar cell, thereby achieving the effect of auxiliary limit.

[0016] 2. The utility model sets a transmission mechanism. When the operator needs to move the clamping plate to fix the solar cell, the operator turns the screw to rotate the rotating support assembly, and then the rotating screw drives the connecting plate to move, and then the connecting plate drives the clamping plate to move, so that the clamping plate fixes the solar cell through the reference plate, ensuring the convenience of the operator in using the clamping plate.

[0017] 3. The utility model sets a limit assembly. When the connecting plate drives the clamping plate to move, the clamping plate will drive the limit plate to slide on the surface of the limit rod, so that the limit plate and the limit rod limit the movement of the clamping plate, thereby preventing the connecting plate and the clamping plate from rotating when the screw rotates.
