Description

Technical Field

[0001] This invention belongs to the field of graphite boat testing technology, and particularly relates to a system and method for inspecting hot-pressed calcined graphite boat finished products. Background Technology

[0002] Graphite boats, as a key component of graphite products, play an indispensable role in high-tech industries such as semiconductors and photovoltaics. In particular, the quality of finished graphite boats produced by hot pressing and calcination directly affects the performance and production efficiency of related products.

[0003] However, the hot-pressing and calcination process is a complex physicochemical process, affected by various factors such as raw material quality, hot-pressing temperature, pressure, and holding time. Even slight fluctuations in these factors can lead to dimensional deviations, shape deformations, and internal defects in the finished graphite boat, thus affecting its performance and product quality in subsequent production. Therefore, it is necessary to inspect the finished graphite boats produced by the hot-pressing and calcination process. In actual inspection scenarios, an automated inspection method based on laser sensors is usually adopted. Specifically, laser sensors are placed in the inspection area, and laser beams are emitted towards the graphite boat. By receiving the reflected laser signals, the propagation time and intensity of the laser signals are used, combined with a pre-set algorithm model, to accurately calculate the dimensional parameters of the graphite boat, such as length, width, and height. At the same time, it can also detect whether its shape meets the design requirements and whether there are internal defects. This inspection method has the advantages of being non-contact, highly accurate, and highly efficient, and can quickly and accurately obtain various key data of the graphite boat.

[0004] Currently, graphite boats manufactured using the hot-pressing and calcining process have two typical structural designs: one is a long, narrow boat-shaped structure with semi-circular closed ends, and the other is a modular cuboid structure. In scenarios involving horizontal conveyor belt transport, the cuboid graphite boat, due to its stable planar characteristics, can better adapt to the positioning requirements of automated inspection systems. However, the long, narrow, streamlined graphite boat, due to its elongated shape, is prone to angular displacement during dynamic transport. This structure lacks reliable planar positioning features, making it difficult for the graphite boat to maintain a perpendicular alignment with the laser sensor in the detection area. In this case, the sensor may not be able to fully capture the edge features of the boat or may experience measurement data distortion, ultimately causing positioning errors in the automated inspection system and a decrease in detection accuracy. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hot-pressed calcined graphite boat finished product inspection system and method that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a hot-pressed calcined graphite boat finished product inspection system, including a conveying unit and a detection unit. The conveying unit includes two vertical plates, and a conveyor belt is arranged between the two vertical plates. The detection unit includes a first laser sensor and a pair of second laser sensors. The first laser sensor is located above the top of the conveyor belt, and the second laser sensors are symmetrically installed above the longitudinal sides of the conveyor belt, and the beam emission direction of the second laser sensors is parallel to the graphite boat finished product in the direction of movement of the conveyor belt. Multiple placement components are equidistantly arranged on the conveyor belt. Among them, the placement components include a pair of rotatable limiting plates. When the two limiting plates are rotated to a first state, the opposing surfaces of the two limiting plates are both arc-shaped cross sections with a preset curvature. At this time, an arc-shaped limiting area is formed between the two limiting plates. When the two limiting plates are rotated from the first state to the second state, the opposing surfaces of the two limiting plates are both horizontal planes. At this time, a square limiting area is formed between the two limiting plates.

[0007] Preferably, each vertical plate has a plurality of equally spaced support rods fixedly connected to its bottom, and a longitudinal connecting rod is fixedly connected between two corresponding support rods located between the longitudinal sides of each conveyor belt, and a transverse connecting rod is fixedly connected between each pair of adjacent longitudinal connecting rods.

[0008] Preferably, a vertical beam plate is fixedly connected to the top of each vertical plate, a longitudinal beam plate is fixedly connected between the tops of two vertical beam plates, a first movable shell is slidably connected to the surface of the longitudinal beam plate, the first laser sensor is installed at the bottom of the first movable shell, a second movable shell is slidably connected to the surface of the vertical beam plate, and the second laser sensor is installed on one side of the two second movable shells respectively.

[0009] Preferably, each of the limiting plates is fixedly connected to a rotating shaft, and a pair of mounting plates that fit against the limiting plates are connected to the two rotating shafts via bearings. The mounting plates are fixedly connected to the surface of the conveyor belt.

[0010] Preferably, a rotating block is fixedly connected to one end of the rotating shaft, and a locking part that cooperates with the rotating block is fixedly connected to the mounting plate.

[0011] Preferably, the rotating block and the locking part are magnetically connected.

[0012] Preferably, the rotating block is made of iron, and the locking part includes an integrally formed horizontal support section, an arc-shaped rotating section, a vertical contact section, and an arc-shaped support section, wherein the horizontal support section and the arc-shaped support section are both made of magnets.

[0013] Preferably, when the rotating block is attached to the horizontal support section, the rotating block is in a horizontal state, and the side of the rotating block that contacts the horizontal support section is a horizontal surface.

[0014] Preferably, when the rotating block is attached between the vertical contact section and the arc-shaped support section, the rotating block is in a vertical state, and the side of the rotating block that contacts the vertical contact section is a horizontal surface, while the side of the rotating block that contacts the arc-shaped support section is an arc-shaped surface.

[0015] This invention also provides a method for inspecting hot-pressed calcined graphite boats, comprising the following steps:

[0016] S1. Adjust the state of the limiting plate according to the shape of the graphite boat to be tested. If the graphite boat to be tested is a long boat shape, manually rotate the two limiting plates to the first state to form an arc-shaped limiting area. If the graphite boat to be tested is a modular cuboid structure, manually rotate the two limiting plates from the first state to the second state to form a square limiting area.

[0017] S2. Place the finished graphite boat to be tested between the adjusted limiting plates, start the conveyor belt, and move the finished graphite boat with the conveyor belt to the bottom of the testing unit.

[0018] S3. The first laser sensor emits a laser beam to detect the height and length of the finished graphite boat, and the second laser sensor emits a laser beam to detect the width and thickness of the finished graphite boat. The detection data is transmitted to the data processing system for analysis to determine whether the finished graphite boat meets the quality standards.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] This invention achieves compatibility and adaptation for two typical graphite boat structures by setting a rotatable limiting plate. When facing a long, narrow, boat-shaped graphite boat, the limiting plate rotates to the first state to form an arc-shaped limiting area. Its arc-shaped cross-section with a preset curvature closely fits the shape of the long, narrow, boat-shaped graphite boat, accurately limiting the angular deviation of the graphite boat during transmission and ensuring that it is always in a vertical state, providing ideal conditions for accurate detection by the first and second laser sensors.

[0021] When processing modular cuboid graphite boats, the limiting plate rotates to its second state to form a square limiting area. The regular square structure perfectly matches the plane of the cuboid graphite boat, providing stable and reliable support and positioning. This effectively avoids positional changes during transport. This design, which flexibly switches the shape of the limiting area according to the characteristics of different graphite boat structures, ensures that graphite boats of different structures maintain a stable and accurate position and posture throughout the inspection process. Whether it is the precise positioning of a long, boat-shaped graphite boat in the arc-shaped limiting area or the stable support of a modular cuboid graphite boat in the square limiting area, the detection unit can always accurately capture features such as boat dimensions and edges, obtaining precise measurement data. This effectively avoids measurement errors caused by graphite boat positional deviation or unstable posture, thus providing reliable data support for the automated inspection system and ensuring high precision and high quality of the inspection results.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1: A hot-pressed calcined graphite boat finished product inspection system, including a conveying unit and a detection unit, which work together to realize automated inspection of the finished graphite boat.

[0037] like Figure 1 As shown, the conveying unit includes two vertical plates 1, and a conveyor belt 11 is set between the two vertical plates 1. It is responsible for orderly conveying the finished graphite boats to be inspected to the inspection area. Each vertical plate 1 has multiple equidistant support rods 12 fixedly connected to its bottom. A longitudinal connecting rod 13 is fixedly connected between two corresponding support rods 12 located on both sides of the longitudinal direction of each conveyor belt 11. A transverse connecting rod 14 is fixedly connected between each pair of adjacent longitudinal connecting rods 13. This design ensures the smooth operation of the conveyor belt 11 and provides a reliable platform for the conveying of finished graphite boats.

[0038] like Figure 1As shown, the detection unit includes a first laser sensor 2 and a pair of second laser sensors 21. The first laser sensor 2 is located above the top of the conveyor belt 11 and is used to detect key parameters such as the height, length, and edge neatness of the finished graphite boat in the vertical direction. The second laser sensors 21 are symmetrically installed above the longitudinal sides of the conveyor belt 11, and the beam emission direction of the second laser sensor 21 is parallel to the finished graphite boat in the direction of movement of the conveyor belt 11. This design can accurately detect parameters such as the width, thickness, and edge neatness of the finished graphite boat in the longitudinal direction.

[0039] To enable the first laser sensor 2 and the second laser sensor 21 to stably detect the finished graphite boat being transported on the conveyor belt 11, such as... Figure 1 As shown, a vertical beam plate 22 is fixedly connected to the top of each vertical plate 1, and a longitudinal beam plate 23 is fixedly connected between the tops of two vertical beam plates 22. A first movable shell 24 is slidably connected to the surface of the longitudinal beam plate 23, and a first laser sensor 2 is installed at the bottom of the first movable shell 24. A second movable shell 25 is slidably connected to the surface of the vertical beam plate 22, and a second laser sensor 21 is installed on the corresponding side of the two second movable shells 25.

[0040] During testing, the finished graphite boats are placed sequentially on conveyor belt 11, and then conveyor belt 11 is started to operate, transporting the finished graphite boats placed on conveyor belt 11 one by one to the testing area of ​​the testing unit. After the finished graphite boats enter the testing area, the first laser sensor 2 and the second laser sensor 21 work together to carry out the testing. The first laser sensor 2 is located above the top of conveyor belt 11. The first laser sensor 2 will accurately detect key parameters of the finished graphite boats in the vertical direction, such as height, length, and edge neatness. Specifically, the first laser sensor 2 emits a laser beam to the surface of the finished graphite boat, receives the reflected laser signal, and accurately calculates the relevant dimensional data of the finished graphite boat in the vertical direction based on the time difference, intensity, and other information of the signal, while judging whether its surface flatness meets the standard requirements.

[0041] Meanwhile, a pair of second laser sensors 21 are symmetrically installed above the longitudinal sides of the conveyor belt 11, with their beam emission direction parallel to the graphite boat finished product moving along the conveyor belt 11. These two second laser sensors 21 emit laser beams from the longitudinal sides of the graphite boat finished product to detect parameters such as the dimensions and edge neatness of the graphite boat finished product in the longitudinal direction. The second laser sensors 21 obtain longitudinal dimension data by measuring the interaction between the laser beam and the edge of the graphite boat finished product during the process from emission to reception, and determine whether the edge is neat, has burrs, or is deformed. Through the comprehensive and accurate detection from different dimensions by the first laser sensor 2 and the second laser sensor 21, the system can promptly detect defects and problems in the graphite boat finished product. Once a product that does not meet the standard is detected, the system can issue a corresponding alarm signal to prompt the operator to handle it, thereby effectively ensuring the quality of the graphite boat finished product.

[0042] Example 2: Considering that there are two typical structural designs for finished graphite boats: one is a long, narrow boat-shaped structure with semi-circular closed ends, and the other is a modular cuboid structure, in the scenario of horizontal conveying by conveyor belt 11, the cuboid graphite boat design has stable planar features and can better adapt to the positioning requirements of the automated detection system. However, the long, narrow, streamlined graphite boat is prone to angular displacement during dynamic transmission due to its narrow and streamlined shape. This structure lacks reliable planar positioning features, making it difficult for the graphite boat to maintain a vertical alignment with the detection area. In this case, the first laser sensor 2 and the second laser sensor 21 may not be able to completely capture the edge features of the boat or the measurement data may be distorted, which will ultimately cause positioning errors in the automated detection system and reduce detection accuracy.

[0043] To solve the above problems, based on the first embodiment described above, as follows: Figures 1-9 As shown, multiple placement components are equidistantly arranged on the conveyor belt 11. Each placement component includes a pair of rotatable limiting plates 3. Each limiting plate 3 is fixedly connected to a rotating shaft 32. A pair of mounting plates 33 that fit against the limiting plates 3 are connected to the two rotating shafts 32 through bearings. The mounting plates 33 are fixedly connected to the surface of the conveyor belt 11.

[0044] Since the two limiting plates 3 are securely fixed to the surface of the conveyor belt 11 by the mounting plate 33, and these two limiting plates 3 are specially designed according to the size and length of the finished graphite boat, when facing the long and narrow boat-shaped graphite boat, the two limiting plates 3 rotate on the mounting plate 33 by means of the pivot 32 until they reach the first state, that is, the two limiting plates 3 overlap each other. At this time, the opposing surfaces of the two limiting plates 3 are both arc-shaped cross sections 31 with a preset curvature, and an arc-shaped limiting area is formed between them, such as... Figures 2-6As shown, this arc-shaped limiting area is highly compatible with the shape of the elongated boat-shaped graphite boat, closely conforming to the contour of the graphite boat. During the process of conveying the graphite boat on the conveyor belt 11, the arc-shaped limiting area can effectively limit the finished graphite boat, effectively preventing the elongated boat-shaped graphite boat from shifting at an angle due to its narrow and streamlined shape. This ensures that the first laser sensor 2 and the second laser sensor 21 can accurately detect it and precisely capture various feature data of the boat body, thereby ensuring that the automated detection system can operate stably and efficiently, greatly improving the accuracy and reliability of the detection.

[0045] When facing a graphite boat with a modular cuboid structure, the two limiting plates 3 rotate from the first state to the second state again using the pivot 32. During this process, as the pivot 32 rotates, the position and angle of the limiting plates 3 change until the opposing surfaces of the two limiting plates 3 become horizontal. At this point, a regular square limiting area is formed between the two limiting plates 3, as shown below. Figures 7-9 As shown, the dimensions of this square restriction area are carefully designed according to the specifications of the modular cuboid graphite boat, and can perfectly fit the plane of the graphite boat. When the conveyor belt 11 transports the modular cuboid graphite boat, this square restriction area can provide stable and reliable support and positioning for the graphite boat. In this way, when the modular cuboid graphite boat enters the detection area, it can always maintain a fixed position and posture, ensuring that the first laser sensor 2 and the second laser sensor 21 can accurately detect it and accurately capture various feature data of the boat body. This ensures that the automated detection system can operate stably and efficiently, greatly improving the accuracy and reliability of the detection.

[0046] This design ensures that graphite boats of different structures maintain a stable and accurate position and posture throughout the inspection process. Whether it is the precise positioning of a long, narrow, boat-shaped graphite boat in the arc-shaped confinement area or the stable support of a modular cuboid graphite boat in the square confinement area, the inspection unit can always accurately capture features such as boat size and edges, and obtain precise measurement data. This effectively avoids measurement errors caused by graphite boat position deviation or unstable posture, thus providing reliable data support for the automated inspection system and ensuring high precision and high quality of the inspection results.

[0047] To further enhance the locking effect of the two limiting plates 3 when adjusted to the first or second state, and to improve the limiting effect of the two limiting plates 3 on the finished graphite boat, such as... Figures 4-9As shown, a rotating block 34 is fixedly connected to one end of the rotating shaft 32, and a locking part that cooperates with the rotating block 34 is fixedly connected to the mounting plate 33. The rotating block 34 and the locking part are magnetically connected. The rotating block 34 is made of iron. The locking part includes an integrally formed horizontal support section 35, an arc-shaped rotating section 36, a vertical contact section 37, and an arc-shaped support section 38. Both the horizontal support section 35 and the arc-shaped support section 38 are made of magnets.

[0048] When the rotating block 34 drives the limiting plate 3 on the rotating shaft 32 to rotate to the first state, the rotating block 34 is in a horizontal state and attached to the horizontal support section 35. At this time, the side of the rotating block 34 in contact with the horizontal support section 35 is a horizontal surface. When the rotating block 34 rotates off the horizontal support section 35 and is attached between the vertical contact section 37 and the arc-shaped support section 38, the rotating block 34 is in a vertical state, and the side of the rotating block 34 in contact with the vertical contact section 37 is a horizontal surface, while the side of the rotating block 34 in contact with the arc-shaped support section 38 is an arc-shaped surface. This design... On the one hand, it can provide a reliable locking function for the limiting plate 3 in the first or second state, ensuring that the limiting plate 3 remains stable in the corresponding state. On the other hand, when the two rotating blocks 34 are in the first state for placing the graphite boat finished product, the adsorption effect of the rotating blocks 34 and the horizontal support section 35 can provide stable support for the limiting plate 3. This provides stable support for the two limiting plates 3 when placing the graphite boat finished product in the first state, effectively avoiding the problem of instability caused by the gravity of the graphite boat finished product itself.

[0049] Furthermore, when the rotating block 34 is in a horizontal state, the two limiting plates 3 are in the first state; when the rotating block 34 is in a vertical state, the two limiting plates 3 are in the second state. In other words, this design can also intuitively and accurately reflect the current state of the limiting plates 3 through the rotating block 34. Without complicated operations or additional testing steps, the staff can quickly determine whether the limiting plates 3 are in the first state, which is adapted to the long, narrow, boat-shaped graphite boat, or the second state, which is adapted to the modular cuboid graphite boat, simply by observing the horizontal or vertical posture of the rotating block 34. This not only greatly simplifies the operation process and reduces testing errors caused by misjudgment of the state, but also effectively improves the working efficiency and reliability of the entire testing system, providing a strong guarantee for the high-quality testing of graphite boats.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
