[0002] Photovoltaic power generation is a green energy and sustainable development energy. Under the country's "carbon neutrality" goal, it has attracted worldwide attention and has been vigorously developed in recent years. With the continuous decline in the cost of photovoltaic power generation, single crystal pulling rods have a broader market space.

[0003] Currently, the entire process of single-crystal silicon ingot pulling utilizes a large number of seed crystals. These seed crystals are engraved with OCR text codes on their end faces to facilitate crystal management, tracking, and traceability. However, after being hollowed, polished, and pickled, the crystals exhibit a metallic luster and reflective properties, making them difficult to identify using conventional code scanning methods. Manual code entry is required, severely impacting operational efficiency and prone to errors. Utility Model Content

In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-3 As shown, the utility model discloses an auxiliary scanning tool, including a box body 1, a sample placer 2 is provided in the box body 1, the sample placer 2 accommodates and fixes the test sample 4, and a detector 3 for photographing the test sample 4 is also provided in the box body 1.

[0034] The sample placer 2 is arranged at the bottom of the box body 1, and a placement slot 11 is opened on the side of the box body 1. A placement surface 21 is provided on the sample placer 2 inside the placement slot 11. The placement surface 21 is a sloped structure. The lower end of the placement surface 21 is close to the placement slot 11, and the higher end of the placement surface 21 is away from the placement slot 11.

[0035] The test sample 4 includes a coaxially connected thin-diameter section 41 and a thick-diameter section 43 . A transitional frustum section 42 is coaxially connected between the thin-diameter section 41 and the thick-diameter end. An OCR text code is provided on the end surface of the thick-diameter section 43 .

[0036] A holding groove 23 is provided on the placement surface 21, and the holding groove 23 is opened downward from the placement surface 21. The holding groove 23 is located on the thin diameter section 41 of the test sample 4. A first card slot 24 and a second card slot 22 are respectively provided on the placement surface 21 on the upper and lower sides of the holding groove 23. The first card slot 24 and the second card slot 22 extend to the top and bottom ends of the placement surface 21 respectively.

[0037] The shape of the first slot 24 matches the thick diameter section 43 and the frustum section 42 of the test sample 4 . In this embodiment, the first slot 24 also matches the thin diameter section 41 on the side close to the gripping slot 23 , and the shape of the second slot 22 matches the thin diameter section 41 .

[0038] The test sample 4 is placed on the placement surface 21 through the placement slot 11 so that the test sample 4 is clamped into the first clamping slot 24 and the second clamping slot 22. The gripping slot 23 provides space for the operator's hands, making it more convenient for the operator to place and take the test sample 4 on the sample placer 2.

[0039] A placement block is provided on the outer wall of the sample placement device 2 at the outer end of the first card slot 24, and a mirror groove 25 is opened on the placement block. A baffle lens (not shown in the figure) is clamped in the mirror groove 25. The baffle lens is perpendicular to the axial direction of the test sample 4, that is, the baffle lens is perpendicular to the opening direction of the first card slot 24 and the second card slot 22.

[0040] The detector 3 includes a support plate 31 arranged in the box 1 on the side of the sample placer 2. The support plate 31 is arranged parallel to the lens barrier. An industrial smart camera 32 is installed on the side of the support plate 31 away from the sample placer 2. A lens slot 33 is provided on the support plate 31 on the side of the lens barrier. The lens of the industrial smart camera 32 is located in the lens slot 33. The axial direction of the lens of the industrial smart camera 32 is perpendicular to the lens barrier, that is, the shooting angle of the industrial smart camera 32 to the end face where the OCR text code of the detection sample 4 is located is ninety degrees.

[0041] A control system electrically connected to the industrial smart camera 32 is provided in the box 1. An openable and closable maintenance door 12 is provided on the top of the box 1. A signal light electrically connected to the control system is provided on the maintenance door 12. A fill light electrically connected to the control system is provided in the box 1 on the side of the lens of the industrial smart camera 32 or above the lens barrier. The control system is electrically connected to the computer to realize signal transmission.

[0042] When scanning the test sample 4, the operator places the test sample 4 on the sample placer 2 through the placement slot 11, so that the end face of the thick diameter section 43 of the test sample 4 contacts the lens and then releases it. The thick diameter section 43 and the frustum section 42 of the test sample 4 are clamped into the first card slot 24, and the second card slot 22 corresponds to the thin diameter section 41 of the test sample 4. The test sample 4 is fixed. At this time, the end face where the OCR text code on the test sample 4 is located is perpendicular to the axial direction of the lens of the industrial smart camera 32. The industrial smart camera 32 takes a photo of the OCR text code for recognition. The control system transfers the recognized OCR text code to the computer and enters it into Excel, then takes out the test sample 4, and puts the next test sample 4 into the sample placer 2, so that multiple test samples 4 can be quickly scanned.

[0043] If the industrial smart camera 32 successfully recognizes the OCR text code, the signal light will turn green. Otherwise, if the recognition is unsuccessful, the signal light will turn red. If the light is insufficient during the process of the industrial smart camera 32 recognizing the OCR text code, the fill light will be used to fill in the light.

[0044] The utility model has a simple structure and low manufacturing and use costs, can quickly scan the test sample 4, greatly improves work efficiency, and avoids operational errors caused by manual code entry. The industrial intelligent camera 32 is fixed at an angle to the end face where the OCR text code is located, and the lens is perpendicular to the end face where the OCR text code is located, avoiding the reflection phenomenon that causes unclear OCR text code, so that the OCR text code can be accurately recognized.

[0045] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
