Description

Technical Field

[0001] This invention relates to the field of graphite boat testing technology, and in particular to an inspection system for graphite boat material processing. Background Technology

[0002] In photovoltaic cell manufacturing processes, the graphite boat serves as the core support tool for critical equipment such as PECVD (plasma-enhanced chemical vapor deposition), and its performance directly determines the uniformity and consistency of silicon wafer coating and the final cell conversion efficiency. To ensure its reliability, the manufacturing of graphite boats follows extremely stringent standards: high-purity isostatic graphite materials must be used to ensure that all physical properties meet the required standards.

[0003] In traditional graphite boat quality inspection, to ensure that key physical properties such as material hardness, flexural strength, and thermal shock resistance meet the requirements, tests are usually performed separately on different specialized equipment or at different workstations. This discrete inspection process has inherent defects.

[0004] First, the testing efficiency is low; the multiple clamping and transfer operations and preparation time significantly slow down the pace of batch sampling inspection. Second, the test data is isolated; performance data measured under different equipment and conditions (such as hardness at room temperature and strength under high temperature conditions) are difficult to effectively correlate and analyze, failing to truly reflect the synergistic and restrictive relationships between performance characteristics. More importantly, the testing conditions are distorted; conventional static and room temperature tests cannot simulate the high temperatures (up to 400℃ or higher) and complex coupled environments of periodic thermal stress impacts that graphite boats endure in actual PECVD processes. This leads to some potential defects, such as microcracks or material inhomogeneities that only appear under alternating stress, not being effectively detected before leaving the factory, ultimately bringing risks into the production line. This could result in batch-specific coating inhomogeneity, increased fragmentation rates, or even serious consequences such as boat breakage. Therefore, an inspection system for graphite boat material processing is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing an inspection system for the processing of graphite boat materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A hot air module is provided at the bottom of the test cabinet. A strip partition is provided above the hot air module. The top of the strip partition is rotatably connected to multiple pins via multiple sets of mounting plates. A dynamic component for simulating the state of the graphite boat components under the condition of carrying silicon wafers for coating is connected to the outer wall of the pins.

[0008] The test cabinet contains two test platforms connected to its top by two hydraulic lifting rods. Multiple test vertical plates are connected to the bottom of each test platform by several vertical rods. Each test vertical plate has a negative pressure groove at its top, and a pressure regulating component is connected within the negative pressure groove to adjust the pressure within it. Two symmetrically arranged hydraulic holes are located at the bottom of each negative pressure groove. A piston plate is connected to the inner wall of each hydraulic hole via a mounting frame. Both the mounting frame and the piston plate have mounting holes, in which a hardness testing component is installed. Multiple sealing covers are fixed to the inner wall of the piston plate within the test vertical plate. A power supply cover is fixed to the outer wall of each sealing cover, and a disconnection component is connected to the outside of the power supply cover. A pressure-applying magnetic column is located inside the sealing cover to move the hardness testing component.

[0009] Preferably, the limiting component includes a limiting telescopic rod fixed to the guide slider, the limiting telescopic rod is fixed with a supporting limiting frame, and the inner sidewalls at both ends of the supporting limiting frame are fixedly connected with elastic folding frames.

[0011] Preferably, the test plumb plates located below the test platform are in pairs, with the two test plumb plates in each pair located on the same vertical plane and fixedly connected by two fixing rods.

[0012] Preferably, the pressure regulating component includes a hydraulic push rod fixed to the bottom of the test platform, the output end of the hydraulic push rod is fixedly connected to a pressure regulating plate, the pressure regulating plate is slidably connected to a negative pressure groove on the test plumb plate, and the test plumb plate is filled with hydraulic oil.

[0013] Preferably, the mounting frame is internally connected to the test plumb plate, the inner wall of the mounting frame is slidably connected to the piston plate, and the mounting frame is filled with inert gas.

[0014] Preferably, the disconnection assembly includes a disconnection frame fixed to the power supply casing, a hydraulic bucket slidably connected to the inner side wall of the disconnection frame via a sliding plate, the bottom end of the sliding plate being fixedly connected to the inner end face of the disconnection frame via a reset telescopic rod, a conductive connecting plate for conducting the circuit inside the power supply casing being fixedly connected to the bottom of the sliding plate, and an electromagnetic column electrically connected to the power supply inside the power supply casing being fixedly connected inside the sealing cover.

[0015] Preferably, the hardness testing assembly includes multiple hardness testing cones, the pressure-applying magnetic column is fixedly connected to the multiple hardness testing cones via a fixed platform, and a pressure platform for testing the flexural strength of the graphite boat is fixedly connected to the outer wall of the fixed platform.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This solution, through the setting of dynamic components, can break through the conventional static and room temperature testing methods. By combining hot air circulation, mechanical excitation and height adjustment, it actively simulates the high temperature, stress change and sudden vibration environment under stress change in the silicon wafer coating process. It simulates the fatigue, stress concentration and performance degradation that graphite boats may encounter in actual use, realizes pre-operational condition inspection, and greatly improves the predictive accuracy of the test.

[0019] 2. This solution, through the setting of the pressure regulating component, can use the pressure adjustment change of the pressure plate in the test plumb plate as a control signal to automatically and sequentially trigger the electromagnetic repulsion to realize the hardness test of the hardness test cone, and use the inert gas in the mounting frame to pressurize and realize the bending test, ensuring that the whole process is smooth and there is no need for manual intervention to switch steps.

[0020] 3. This solution, through the setup of hardness testing components and pressure table, can utilize the strong repulsive force generated instantaneously by electromagnetic induction to achieve high-speed and high-consistency driving of the hardness testing cone, ensuring uniform impact energy and making the comparison of multi-point hardness data more reliable. Furthermore, by pressurizing the inert gas within the mounting frame, a stable, controllable, and accurately measurable bending load is provided, which is superior to simple mechanical pressure, making the overall test data more accurate and reliable.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Example, refer to Figures 1 to 13An inspection system for processing graphite boat materials includes a test cabinet 1 for testing graphite boat 3. The inner wall of the test cabinet 1 is connected to two sets of symmetrically arranged lifting guide rails 4. The inner wall of the lifting guide rails 4 is connected to a limiting component for limiting the position of the graphite boat 3 via a guide slider 5. A hot air module is provided at the bottom of the test cabinet 1. A strip partition 2 is provided above the hot air module. Multiple pins are rotatably connected to the top of the strip partition 2 via multiple sets of mounting plates. A dynamic component for simulating the state of the graphite boat 3 under the condition of carrying silicon wafers for coating is connected to the outer wall of the pins.

[0039] Furthermore, the limiting component includes a limiting telescopic rod fixed to the guide slider 5, the limiting telescopic rod is fixed with a supporting limiting frame 6, and elastic folding frames 7 are fixedly connected to the inner sidewalls at both ends of the supporting limiting frame 6. The dynamic component includes multiple impeller parts 8 fixed to the outer sidewall of the pin shaft, multiple conical disks 9 are fixedly connected to the outer sidewall of the pin shaft, and multiple protrusions arranged in a circular array are fixedly connected to the edge of the conical disks 9. The conical disks 9 are disposed in the gaps of the graphite boat parts 3.

[0040] It should be noted that: the frame of the graphite boat 3 to be tested is placed inside the support and limiting frames 6 on both sides, and the two elastic folding frames 7 inside the support and limiting frames 6 clamp and limit the graphite boat 3 to achieve the initial limiting of the graphite boat 3. Then, the guide slider 5 is controlled to slide in the lifting guide rail 4 to adjust the contact state between the graphite boat 3 and the conical disk 9. At the same time, the hot air module at the bottom of the test cabinet 1 is activated, and hot air will flow upward through the strip partition 2. The flowing air will drive the impeller 8 to rotate. The rotation of the impeller 8 will drive the conical disk 9 to rotate together through the pin shaft. The rotating conical disk 9 will excite the entire graphite boat 3 with a small amplitude. During this process, the height of the graphite boat 3 is continuously adjusted to simulate the state of the graphite boat 3 being affected by external forces intermittently, and to reproduce the stress change state of the graphite boat 3 when loading silicon wafers for coating at high temperature.

[0041] The advantages mentioned above are: this can simulate the state of the graphite boat 3 under the high temperature coating condition of silicon wafer, which makes it easier to test whether its various physical properties are qualified under the extreme conditions of the use of the graphite boat 3.

[0042] The top of the test cabinet 1 is connected to two test platforms 11 by two hydraulic lifting rods 10. The bottom of the test platform 11 is connected to multiple test plumb plates 12 by multiple vertical rods. The top of the test plumb plate 12 is provided with a negative pressure groove. The negative pressure groove of the test plumb plate 12 is connected to a pressure regulating component for adjusting the pressure state in the negative pressure groove. The bottom of the negative pressure groove of the test plumb plate 12 is provided with two symmetrically arranged hydraulic holes. The inner side wall of the hydraulic holes is connected to a piston plate 16 by a mounting frame 15. Both the mounting frame 15 and the piston plate 16 are provided with mounting holes. The hardness test component is installed in the mounting holes. Multiple sealing covers 17 are fixed on the side wall of the piston plate 16 located inside the test plumb plate 12. A power supply cover 18 is fixed on the outer side wall of the sealing cover 17. A disconnection component is connected to the outside of the power supply cover 18. The inner side of the sealing cover 17 is provided with a pressure magnetic column 23 for pushing the hardness test component to move.

[0043] Furthermore, the test plumb plates 12 located below the test platform 11 are arranged in pairs, with the two test plumb plates 12 in each pair located on the same vertical plane and fixedly connected by two fixing rods. The pressure regulating assembly includes a hydraulic push rod 13 fixed to the bottom of the test platform 11, and a pressure regulating plate 14 fixedly connected to the output end of the hydraulic push rod 13. The pressure regulating plate 14 is slidably connected to the negative pressure groove on the test plumb plate 12. The test plumb plate 12 is filled with hydraulic oil. The mounting frame 15 is connected to the interior of the test plumb plate 12, and the inner wall of the mounting frame 15 is slidably connected to the piston plate 16. The mounting frame 15 is filled with inert gas. The disconnection assembly includes a disconnection frame 19 fixed to the power supply casing 18. The inner wall of the disconnection frame 19 is connected by a sliding... The slide plate is slidably connected to a hydraulic bucket 20. The bottom end of the slide plate is fixedly connected to the inner end face of the disconnect frame 19 via a reset telescopic rod. A conductive connecting plate 21 for conducting the circuit inside the power supply cover 18 is fixedly connected to the bottom of the slide plate. An electromagnetic column 22 that is electrically connected to the power supply inside the power supply cover 18 is fixedly connected inside the sealing cover 17. The hardness testing assembly includes multiple hardness testing cones 25. A pressure magnetic column 23 is fixedly connected to multiple hardness testing cones 25 via a fixed platform 24. A pressure platform 29 for testing the flexural strength of the graphite boat 3 is fixedly connected to the outer wall of the fixed platform 24. The pressure platform 29 is slidably connected to the mounting frame 15. The pressure magnetic column 23 is slidably connected to the piston plate 16. The pressure platform 29 is fixedly connected to the piston plate 16.

[0044] Multiple storage holes are provided on the pressure table 29. An elastic corrugated sleeve 26 is fixedly connected to the inner wall of one end of the fixed table 24 located on one side of the storage hole. The inner wall of the front end of the elastic corrugated sleeve 26 is fixedly connected to the hardness test cone 25. Multiple polarization lasers 27 are fixed on the outer wall of the hardness test cone 25 located in the middle. Laser sensing plates 28 are fixed on the outer walls of the multiple hardness test cones 25 located on the edge.

[0045] It should be noted that when testing the physical properties of the graphite boat 3, the two hydraulic lifting rods 10 are controlled to move the two test platforms 11 downwards sequentially, allowing the test plumb plate 12 to enter the gap of the graphite boat 3. Then, the hydraulic push rod 13 is controlled to push the pressure regulating plate 14 downwards to a certain distance and stop. Under the pressure of the pressure regulating plate 14, the hydraulic pressure inside the test plumb plate 12 will increase to a certain extent, causing the hydraulic bucket 20 to be pressurized and the sliding plate to move downwards. The downward movement of the sliding plate will cause the conductive connecting plate 21 to move downwards, thereby connecting the circuit inside the power supply casing 18 and supplying a strong current to the electromagnetic column 22 inside the sealing casing 17. This causes the electromagnetic column 22 to become instantly strongly magnetic, generating a strong magnetic repulsion force on the pressure-applying magnetic column 23, thus increasing the pressure... The magnetic column 23 drives multiple hardness testing cones 25 to impact and pierce the surface of the graphite boat 3 via the fixed platform 24. When the surface hardness of the graphite boat 3 is inconsistent, the penetration depth of the hardness testing cones 25 will also be different. By measuring the displacement change of the polarization laser 27 on the outer wall of the hardness testing cone 25 and the peripheral laser sensing plate 28 located in the cavity of the pressure platform 29, the hardness testing cones 25 are compared with each other to determine whether the hardness of the test area of ​​the graphite boat 3 is consistent. Subsequently, the indentation on the side wall of the graphite boat 3 is photographed and recorded as a record for batch sampling inspection. This can quickly complete the hardness test of the graphite boat 3 under actual working conditions and ensure that the hardness of the graphite boat 3 is qualified during actual use.

[0046] After the hardness test is completed, the pressure regulating plate 14 is pressed down by the hydraulic push rod 13, which increases the hydraulic pressure in the test vertical plate 12. The hydraulic bucket 20 is pressed down and moves down, which in turn drives the conductive connecting plate 21 to move down and disconnect from the circuit connection in the power supply cover 18. This disconnects the electromagnetic column 22 from the power supply, and the magnetic repulsion force on the pressure magnetic column 23 disappears. The hardness test cone 25 is elastically reset under the action of the elastic corrugated sleeve 26 and is re-stored in the cavity of the pressure table 29. At the same time, as the hydraulic pressure in the test vertical plate 12 continues to increase, the piston plate 16 in the mounting frame 15 is pressed, which pressurizes the inert gas in the mounting frame 15. This allows the piston plate 16 to slowly push the pressure table 29 outward, so that the pressure table 29 can be pressed tightly against the side wall of the graphite boat 3.

[0047] The advantages mentioned above are: allowing the graphite boat 3 to be locally subjected to pressure and bending, conducting continuous bending tests on multiple parts of the graphite boat 3, and then using a level measuring instrument to detect whether the plate on the graphite boat 3 has deformed and bent, which is used as a reference to see whether the flexural strength of the graphite boat 3 under stress during the silicon wafer coating process meets the standard.

[0048] In use, this invention performs destructive sampling tests on batches of graphite boat parts 3. First, the test cabinet 1 is opened. Then, the frame of the graphite boat part 3 to be tested is placed within the supporting and limiting frames 6 on both sides. The two elastic folding frames 7 within the supporting and limiting frames 6 clamp and limit the graphite boat part 3, achieving initial positioning. Then, the guide slider 5 is controlled to slide within the lifting guide rail 4, adjusting the contact state between the graphite boat part 3 and the conical disc 9. Simultaneously, the hot air module at the bottom of the test cabinet 1 is activated, causing hot air to continuously flow upwards through the strip partition 2. The airflow will drive the impeller 8 to rotate, and the rotation of the impeller 8 will drive the conical disk 9 to rotate together through the pin. The rotating conical disk 9 will cause small-amplitude excitation to the entire graphite boat 3, and continuously adjust the height of the graphite boat 3 during this process, simulating the state of the graphite boat 3 being affected by external forces intermittently, and reproducing the stress change state of the graphite boat 3 when loading silicon wafers for coating at high temperature. This can simulate the state of the graphite boat 3 under the high temperature coating condition of silicon wafers, which is convenient for subsequent testing of its various physical properties under the extreme working conditions of the graphite boat 3.

[0049] During the testing of the physical properties of the graphite boat 3, two hydraulic lifting rods 10 are controlled to move the two test platforms 11 downwards sequentially, allowing the test plumb plate 12 to enter the gap of the graphite boat 3. Then, the hydraulic push rod 13 is controlled to push the pressure regulating plate 14 downwards to a certain distance and stop. Under the pressure of the pressure regulating plate 14, the hydraulic pressure inside the test plumb plate 12 increases to a certain extent, causing the hydraulic bucket 20 to be pressurized and the sliding plate to move downwards. The downward movement of the sliding plate causes the conductive connecting plate 21 to move downwards, thereby activating the circuit inside the power supply enclosure 18. This allows a strong current to flow through the electromagnetic column 22 inside the sealing cover 17, causing the electromagnetic column 22 to momentarily become strongly magnetic, generating a strong magnetic repulsion force on the pressure magnetic column 23. Multiple hardness testing cones 25 driven by the fixed stage 24 impact and puncture the surface of the graphite boat 3. When the surface hardness of the graphite boat 3 is inconsistent, the penetration depth of the hardness testing cones 25 will also be different. By measuring the displacement change of the polarization laser 27 on the outer wall of the hardness testing cone 25 and the peripheral laser sensing plate 28 located in the cavity of the pressure stage 29, the hardness testing cones 25 are compared with each other to determine whether the hardness of the test area of ​​the graphite boat 3 is consistent. Subsequently, the indentation on the side wall of the graphite boat 3 is photographed and recorded as a record of batch sampling inspection. In this way, the hardness test of the graphite boat 3 under actual working conditions can be completed quickly, ensuring that the hardness of the graphite boat 3 is qualified in actual use.

[0050] After the hardness test is completed, the hydraulic push rod 13 continues to press the pressure regulating plate 14 downward, increasing the hydraulic pressure in the test plumb plate 12. This causes the hydraulic bucket 20 to continue moving downward under pressure, which in turn moves the conductive connecting plate 21 downward, disengaging it from the circuit connection inside the power supply enclosure 18. This disconnects the electromagnetic column 22 from power, causing the magnetic repulsion force on the pressure magnetic column 23 to disappear. The hardness testing cone 25 elastically resets under the action of the elastic corrugated sleeve 26 and is repositioned in the cavity of the pressure table 29. Simultaneously, as the hydraulic pressure in the test plumb plate 12 continues to increase... When the piston plate 16 inside the mounting frame 15 is pressurized, it pressurizes the inert gas inside the mounting frame 15, allowing the piston plate 16 to slowly push the pressure table 29 outward, so that the pressure table 29 can press against the side wall of the graphite boat 3, causing the graphite boat 3 to bend under local pressure. This is a continuous bending resistance test of multiple parts of the graphite boat 3. Subsequently, a level measuring instrument is used to detect whether the plate on the graphite boat 3 has deformed and bent, which is used as a reference to see whether the flexural strength of the graphite boat 3 under stress during the silicon wafer coating process meets the standard.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
