[0001] The utility model relates to photovoltaic power generation technical field, concretely relates to a kind of photovoltaic solar cell detection probe array. BACKGROUND
[0002] In the production process of photovoltaic solar cell, to ensure the quality and performance of product, the cell needs to be detected, and various types of detection probe array are often used in the detection process. The traditional photovoltaic solar cell detection probe array is generally composed of a fixed plate and a plurality of probes arranged on the fixed plate. These probes contact with specific parts of the cell during detection, and the performance of the cell is evaluated by detecting its current, voltage and other electrical characteristics.
[0003] However, the protection measures of the traditional detection probe array for the probes are not perfect. After the detection operation is completed, the probes are usually directly exposed to the outside, which is easy to be contaminated and damaged by the external environment, which not only affects the service life of the probes, but also may cause the accuracy of subsequent detection to decrease.

[0008] a sleeve shell arranged on the fixed plate along the length direction of the probe at the bottom end, the sleeve shell can be telescopic, so as to expose the detection end of the probe.
[0009] The sleeve shell is provided with a roller in rolling contact with the two sides of the probe, and the probe extends out from between the two rollers when the sleeve shell slides upward.
[0010] A limiting groove is provided on the roller corresponding to the probe, and the side of the probe is located in the limiting groove.

[0019] The present application will be further described in conjunction with the specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present application and are not used to limit the scope of the present application. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "in" and "out" refer to the directions towards or away from the geometric center of a particular component.
[0020] Embodiment 1: as shown in the drawing, a photovoltaic solar cell detection probe array comprises: Figures 1-3
[0021] a fixed plate 1; as the basic structure of the whole probe array, it provides mounting positions for probes 2 and provides support for the installation of subsequent components;
[0022] a plurality of probes 2 arranged on the fixed plate 1; the probes 2 are key components for detecting photovoltaic solar cells, and they will contact the specific parts of the cells during the detection process, and evaluate the performance of the cells by detecting the electrical characteristics such as current and voltage;
[0023] A sleeve 3, with its bottom end slidably mounted on the fixed plate 1 along the length of the probe 2, is retractable to expose the detection end of the probe 2. The sleeve 3 has a telescopic function, enabling the concealment and exposure of the detection end of the probe 2. When the sleeve 3 is retracted, the detection end of the probe 2 is hidden; when the sleeve 3 is extended, the detection end of the probe 2 is exposed to contact the photovoltaic solar cell and complete the detection operation. After detection, the sleeve 3 extends, covering the detection end of the probe 2 inside the sleeve 3, thus protecting the probe 2.
[0024] In the specific design, the two ends of the sleeve 3 are slidably fitted onto the vertically arranged guide rod 5. A spring 6 is fitted onto the guide rod 5, with one end of the spring 6 acting on the sleeve 3 and the other end acting on a limiting block 7 located on the guide rod 5. The two ends of the sleeve 3 are slidably fitted onto the vertically arranged guide rod 5, which provides a track for the sliding of the sleeve 3, limiting the sliding direction of the sleeve 3 and ensuring that it can only slide vertically up and down, thereby guaranteeing the accuracy and stability of the operation.
[0025] Two sleeves 3 are provided, and the two sleeves 3 are respectively located on the front and rear sides of the fixing plate 1. This can protect both sides of the probe 2.
[0026] Example 2: As Figures 3-4 As shown, rollers 4 are arranged inside the housing 3 on both sides corresponding to the probe 2, engaging in rolling contact with it. When the housing 3 slides upward, the probe 2 extends out between the two rollers 4. The rollers 4 and the probe 2 are in rolling contact; when the probe 2 extends, the rollers 4 roll along with the movement of the probe 2. Due to the rolling characteristics of the rollers 4, they can guide the extension movement of the probe 2, making the probe 2 extend more smoothly from the housing 3. At the same time, the rolling of the rollers 4 reduces the friction between the probe 2 and the housing 3, avoiding excessive friction that would hinder the extension movement of the probe 2, ensuring that the probe 2 can extend along the expected trajectory.
[0027] The roller 4 is provided with a limiting groove 41 corresponding to the probe 2, and the side of the probe 2 is located in the limiting groove 41. When the probe 2 is extended from the sleeve 3, the rollers 4 on both sides of the probe 2 can play a positioning role. Due to the limiting groove 41 on the roller 4, the side of the probe 2 is located in the limiting groove 41, so that the position of the probe 2 is limited in the range defined by the groove 41 during extension. The positioning effect can ensure that the probe 2 extends along the predetermined direction and prevents it from deviating during extension, ensuring the position accuracy of the probe 2.
[0028] The two rollers 4 on both sides of the probe 2 are arranged in an up-down staggered manner.
[0029] When the two rollers 4 are arranged in an up-down staggered manner, the up-down staggered rollers 4 can cover a larger height range in the vertical direction. When the probe 2 is extended or retracted, the up-down staggered rollers 4 can limit the probe 2 at different height positions, which can better prevent the probe 2 from excessive displacement in the vertical direction and provide wider vertical direction limiting capability.
[0030] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, some improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
