[0002] Photovoltaic silicon wafers are the core component of solar power generation systems. Their function is to convert solar energy into electrical energy or directly power loads. Therefore, the quality and cost of photovoltaic silicon wafers directly determine the quality and cost of the entire solar power generation system. One of the key steps in the production of photovoltaic silicon wafers is to form circuits and electrodes on the surface of the photovoltaic silicon wafer using a squeegee screen printing technique. The hardness of the squeegee has a strong correlation with the screen printing quality.
[0003] In the standardized testing of scraper hardness, the strength of the wire mesh scraper is usually tested using a hardness tester. Some testing devices use bolts to position and lock the scraper, which requires rotating the bolts before and after the scraper test, which is slightly inconvenient. Therefore, a tooling for standardized testing of scraper hardness in photovoltaic applications is needed. This tooling can use clamps to position the scraper on the testing table, ensuring the stability of the scraper during the hardness testing process and allowing for quick assembly and disassembly of the scraper, thereby improving the convenience of scraper hardness testing.

[0010] Preferably, the movable hardness tester and the electric telescopic rod are both electrically connected to the control box via wires.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model places the scraper to be tested on the top of the testing table, then activates the electric telescopic rod to move the push-pull plate, which in turn moves the slider through the pivot shaft. The slider then moves the clamping plate through the connecting rod to position the scraper to be tested on the top of the testing table. This achieves the purpose of positioning the scraper on the testing table by the clamping plate, ensuring the stability of the scraper during the hardness testing process and allowing for quick assembly and disassembly of the scraper, thereby improving the convenience of scraper hardness testing.
[0013] 2. By setting up a rotating sleeve, this utility model provides padding between the inner wall of the rotary shaft and the push-pull plate, avoiding excessive wear when the two are in direct contact, thereby extending their service life.
[0014] 3. This utility model limits the movement of the push-pull plate by setting the clamping block, thus preventing the push-pull plate from shaking during the movement.
[0015] 4. This utility model protects the surface of the clamping plate by setting a pad strip, thus preventing damage to the surface of the scraper plate when the clamping plate comes into direct contact with the scraper plate to be tested.
[0016] 5. By setting a stop bar, this utility model limits the position of the scraper to be tested on the top of the testing table, thereby improving the accuracy of the scraper's position on the top of the testing table. Attached Figure Description

[0024] In the following description, embodiments of the tooling for standardized testing of scraper hardness in photovoltaic applications will be presented with reference to the accompanying drawings.
[0025] Example 1:
[0026] Figure 1-4 This invention illustrates a fixture for standardized testing of the hardness of a photovoltaic scraper, comprising a testing platform 1. A fixing plate 2 is bolted to the bottom of the testing platform 1. An electric telescopic rod 3 and a slide rail 4 are bolted to the bottom of the fixing plate 2. A slider 5 is slidably connected to the surface of the slide rail 4. A push-pull plate 6 is fixedly connected to the output end of the electric telescopic rod 3 via a flange. A pivot 7 is integrally formed at the bottom of the slider 5, with its bottom end extending into the inner cavity of the push-pull plate 6. A rotating sleeve 8 is rotatably connected to the surface of the pivot 7, and the surface of the rotating sleeve 8 fits against the inner wall of the push-pull plate 6. The rotating sleeve 8 provides padding between the pivot 7 and the inner wall of the push-pull plate 6. This avoids excessive wear when the two are in direct contact, thus extending their service life. A connecting rod 9 is fixedly connected to the surface of the slider 5. Two symmetrically arranged clamping blocks 10 are fixedly connected to the bottom of the fixing plate 2 by bolts. The inner wall of the clamping block 10 is in contact with the push-pull plate 6. The clamping block 10 limits the movement of the push-pull plate 6, preventing the push-pull plate 6 from shaking during movement. A clamping plate 11 is welded to the end of the connecting rod 9. The scraper to be tested 13 is placed on the top of the testing table 1. A base plate 15 is fixedly installed on the bottom of the testing table 1. A movable hardness tester 16 and a control box 17 are installed on the top of the base plate 15.
[0027] Example 2:
[0028] Figure 1-4This invention illustrates a fixture for standardized testing of the hardness of a photovoltaic scraper, comprising a testing platform 1. A fixing plate 2 is bolted to the bottom of the testing platform 1. An electric telescopic rod 3 and a slide rail 4 are bolted to the bottom of the fixing plate 2. A slider 5 is slidably connected to the surface of the slide rail 4. A push-pull plate 6 is fixedly connected to the output end of the electric telescopic rod 3 via a flange. A pivot shaft 7 is integrally formed at the bottom of the slider 5. A connecting rod 9 is fixedly connected to the surface of the slider 5. A clamping plate 11 is welded to the end of the connecting rod 9. A scraper 13 to be tested is placed on the top of the testing platform 1. A rubber strip 12 is adhered to the surface of the clamping plate 11. The design includes a protective cover for the surface of the clamping plate 11, preventing damage to the surface of the scraper 13 when it comes into direct contact with the plate. A base plate 15 is fixedly installed at the bottom of the testing platform 1, and a movable hardness tester 16 and a control box 17 are installed on the top of the base plate 15. A stop bar 14 is welded to the top of the testing platform 1, and the rear side of the scraper 13 to be tested is in contact with the front side of the stop bar 14. The stop bar 14 limits the position of the scraper 13 to be tested on the top of the testing platform 1, improving the accuracy of the position of the scraper 13 to be tested on the top of the testing platform 1. The movable hardness tester 16 and the electric telescopic rod 3 are electrically connected to the control box 17 via wires.
[0029] Working principle: When using this utility model, the user places the scraper 13 to be tested on the top of the testing platform 1, and then controls the electric telescopic rod 3 to move the push-pull plate 6 through the control box 17. The push-pull plate 6 then moves the slider 5 through the pivot shaft 7. During this process, the slider 5 is limited by the slide rail 4, ensuring the stability of the slider 5 during movement. Then, the slider 5 moves the clamping plate 11 through the connecting rod 9 to position the scraper 13 to be tested on the top of the testing platform 1. Subsequently, the movable hardness tester 16 is controlled by the control box 17 to perform multi-point hardness testing on the scraper 13. This achieves the positioning of the scraper on the testing platform by the clamping plate, ensuring the stability of the scraper during the hardness testing process and allowing for quick assembly and disassembly of the scraper, thereby improving the convenience of scraper hardness testing.
[0030] In summary, this fixture for standardized hardness testing of photovoltaic scrapers allows for the following: The scraper to be tested 13 is placed on top of the testing platform 1. Then, the electric telescopic rod 3 is activated to move the push-pull plate 6. The push-pull plate 6, via the pivot shaft 7, moves the slider 5. The slider 5, through the connecting rod 9, moves the clamping plate 11 to position the scraper to be tested 13 on top of the testing platform 1. This achieves the clamping plate's positioning of the scraper on the testing platform, ensuring the stability of the scraper during hardness testing and allowing for quick assembly and disassembly of the scraper, thereby improving the convenience of scraper hardness testing.
