Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor measurement, in particular to a crystal rod measuring vehicle. Background Art

[0002] Polycrystalline silicon is the primary raw material for the production of solar photovoltaic and semiconductor products. The Czochralski (Cz) process is one of the most commonly used methods for producing single-crystal silicon. High-purity solid polycrystalline silicon feedstock is melted in a crucible within a crystal growth furnace (single crystal furnace) to form a melt. A seed crystal is lowered by a seed crystal lifting mechanism into contact with the molten silicon in a rotating crucible. The seed crystal is then pulled out according to a specific process, and the melt solidifies around the seed crystal to form a single-crystal silicon rod.

[0003] In the prior art, after production is completed, single crystal silicon rods need to be removed from the single crystal furnace. During the process of removing the crystal rods, a crystal rod trolley is usually used to complete the removal of the crystal rods. However, since the surface temperature of the crystal rods is high when they are removed, the diameter of the crystal rods cannot be manually measured at this time. Therefore, the operator usually uses a caliper to measure the diameter of the crystal rods after the crystal rods have cooled. However, this measurement method has a low degree of automation, low measurement efficiency, large measurement errors, and few measurement points. As a result, process personnel are unable to timely access accurate diameter data to study and analyze methods to improve crystal growth. At the same time, the caliper directly contacts the surface of the crystal rod, which can easily cause metal contamination to the crystal rod. In addition, the existing crystal rod trolley cannot directly position when receiving the crystal rods. The operator needs to adjust the position of the crystal rod trolley multiple times, resulting in low reception efficiency.

[0004] Therefore, there is an urgent need for a crystal rod retrieval vehicle that can reduce manual operations, obtain the external dimension data of the single crystal silicon rod as soon as the single crystal silicon rod is taken out of the furnace, and facilitate the retrieval of the crystal rod. Utility Model Content

[0005] The purpose of the utility model is to provide a crystal rod measuring vehicle, which can not only automatically locate the position for receiving the crystal rod, but also measure the full diameter size of the single crystal silicon rod in real time during the process of the turning rack receiving the crystal rod, thereby reducing manual operation and improving the receiving efficiency.

[0021] Beneficial effects of the utility model:

[0022] The utility model provides a crystal ingot measuring vehicle, which arranges a measuring component on a turning frame.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0036] like Figure 1 and Figure 2As shown, the present invention provides a crystal ingot measuring vehicle that can not only quickly access a crystal ingot 8 but also measure the diameter of the crystal ingot 8 in real time during the access process. Specifically, the crystal ingot measuring vehicle includes a vehicle frame 1, a turning frame 2, a measuring assembly 3, and a positioning device 4. The positioning device 4 is mounted on the vehicle frame 1 and is used to read positioning marks on the ground to position the crystal ingot measuring vehicle at the access position for the crystal ingot 8. The turning frame 2 is rotatably connected to the vehicle frame 1. After the crystal ingot measuring vehicle stops at the access position for the crystal ingot 8, the crystal ingot 8 is removed from the pulling chamber, and the turning frame 2 is simultaneously rotated to the target angle to access the crystal ingot 8. The measuring assembly 3 is mounted on the turning frame 2 and can measure the diameter of the crystal ingot 8 in real time.

[0037] like Figure 1 and Figure 2 As shown, the flip frame 2 includes a support part 21, a limit frame 22 and a bottom support 23, wherein the support part 21 is roughly rectangular and includes multiple rods connected horizontally and vertically. The limit frame 22 is fixed on the support part 21, and several limit frames 22 are arranged at intervals along the length direction of the support part 21. The number of limit frames 22 can be set according to needs and is not limited here. A limit space that can accommodate and limit the crystal rod 8 is formed between the limit frame 22 and the support part 21. The bottom support 23 is arranged at one end of the support part 21 and is opposite to the limit frame 22. The crystal rod 8 entering the limit space moves to the bottom support 23. The bottom support 23 is used to support the bottom surface of the crystal rod 8, so that the crystal rod 8 cannot continue to move. When the turning frame 2 is rotated to the target angle, the crystal ingot 8 pulled out from the pulling chamber can pass through several limit frames 22 one by one until the bottom surface of the crystal ingot 8 is supported on the bottom support 23. Several limit frames 22 are spaced around the outer circumference of the crystal ingot 8 along the length direction of the crystal ingot 8, so that the limit frames 22 can limit the circumference of the crystal ingot 8 to prevent the crystal ingot 8 from falling sideways and being damaged.

[0038] Alternatively, as Figure 1 As shown, the support portion 21 is provided with a plurality of guide wheel groups spaced apart along its length direction, each guide wheel group including at least one first guide wheel 211, each first guide wheel 211 can rotate around its own rotation axis, and the first guide wheel 211 is used to guide the crystal rod 8 to enter and exit the limited space. Figure 1As shown, each guide wheel assembly includes two first guide wheels 211, which are arranged in pairs on the crossbars of the support portion 21. Multiple pairs of first guide wheels 211 are spaced apart along the length of the support portion 21. The first guide wheels 211 are cylindrical, and the two first guide wheels 211 in each guide wheel assembly form a V-shaped structure with the same opening direction. When the crystal ingot 8 passes through the confined space, the surface of the crystal ingot 8 contacts the first guide wheels 211, causing sliding between the two. Under the guidance of the multiple guide wheel assemblies, the crystal ingot 8 gradually moves, and the movement trajectory is defined by the multiple guide wheel assemblies as a straight line, thereby preventing the crystal ingot 8 from colliding with the confining frame 22 during movement and being scratched.

[0039] Alternatively, as Figure 1 As shown, the limiting frame 22 is also provided with a second guide wheel 221. The second guide wheel 221 is arranged opposite the first guide wheel 211, and the second guide wheel 221 cooperates with the first guide wheel 211 to guide the crystal ingot 8 into and out of the limiting space. When the crystal ingot 8 passes through the limiting space, the two opposing surfaces of the crystal ingot 8 contact the first guide wheel 211 and the second guide wheel 221, respectively. Under the guidance of the first guide wheel 211 and the second guide wheel 221, the crystal ingot 8 gradually moves. The movement trajectory is defined as a straight line by the first guide wheel 211 and the second guide wheel 221, which can further prevent the crystal ingot 8 from colliding with the limiting frame 22 during movement and causing scratches. At the same time, the first guide wheel 211 and the second guide wheel 221 can also provide a certain clamping effect on the crystal ingot 8, further ensuring the stability of the crystal ingot 8 during movement. Optionally, the second guide wheel 221 is a guide wheel with a guide groove along its circumference.

[0040] Furthermore, since the diameters of the crystal rod 8 pulled out of the pulling chamber are different in the length direction, in order to prevent the crystal rod 8 from being clamped by the first guide wheel 211 and the second guide wheel 221 and unable to move, as shown in FIG. Figure 1 As shown, in this embodiment, a movable adjusting member 222 is further provided on the limiting frame 22, and the second guide wheel 221 is mounted on the adjusting member 222. Specifically, as Figure 2 As shown, the adjustment member 222 includes a limit head 2221, a slide bar 2222, and a mounting plate 2223. The slide bar 2222 is inserted into the crossbar of the limit frame 22, and one end of the slide bar 2222 is located inside the limit frame 22, while the other end is located outside the limit frame 22. The limit head 2221 is provided at the end of the slide bar 2222 located outside the limit frame 22, and the mounting plate 2223 is provided at the end of the slide bar 2222 located inside the limit frame 22. The limit head 2221 and the mounting plate 2223 can limit the sliding range of the slide bar 2222. Furthermore, the mounting plate 2223 is further provided with two clamping blocks at both ends away from the slide bar 2222, with a rotating shaft provided between the two clamping blocks. The second guide wheel 221 is inserted into the rotating shaft and can rotate around the rotating shaft, and the second guide wheel 221 is limited between the two clamping blocks.

[0041] When the diameter of the crystal rod 8 increases during the process of passing through the first guide wheel 211 and the second guide wheel 221, the second guide wheel 221 and the adjustment member 222 can be pushed to move toward the outside of the limit frame 22, thereby enabling the first guide wheel 211 and the second guide wheel 221 to have a certain clamping effect on the crystal rod 8 without hindering the movement of the crystal rod 8.

[0042] like Figure 1 and Figure 2 As shown, the turning frame 2 is also equipped with a measuring assembly 3, which is used to measure the diameter of the crystal ingot 8 in real time. Specifically, the measuring assembly 3 includes a mounting frame 31 and a measuring instrument 32. The mounting frame 31 has a through-hole formed in it for the crystal ingot 8 to pass through, and the measuring instrument 32 is mounted on the turning frame 2 via the mounting frame 31. Furthermore, the measuring assembly 3 is mounted on the top of the turning frame 2 when it is at the target angle. This arrangement allows the measuring assembly 3 to measure the entire diameter of the crystal ingot 8 in real time as the crystal ingot 8 is removed from the pulling chamber and placed into the turning frame 2, allowing personnel to analyze and adjust the process based on the real-time data.

[0043] Alternatively, as Figure 2 and Figure 4 As shown, in this embodiment, the measuring instrument 32 is a laser measuring instrument. The laser measuring instrument includes two transmitting ends 321 and two receiving ends 322. The two transmitting ends 321 and the two receiving ends 322 are respectively arranged at the four corners of the mounting frame 31, and each transmitting end 321 corresponds to one receiving end 322. When the turning frame 2 receives the crystal ingot 8, the crystal ingot 8 moves downward through the mounting frame 31. At this time, the laser emitted by the transmitting end 321 of the laser measuring instrument is partially blocked by the crystal ingot 8. The receiving end 322 of the laser measuring instrument calculates the diameter of the crystal ingot 8 at this location based on the width of the received laser. It should be noted that the transmitting end 321 and the receiving end 322 of the laser measuring instrument are not limited to two sets, as long as the width of the laser emitted by the transmitting end 321 of the laser measuring instrument is greater than the diameter of the crystal ingot 8. It is understandable that in some other embodiments, the measuring instrument 32 can also be other measuring devices, such as using an infrared scanner to collect the diameter changes of the crystal ingot 8, which is not limited here.

[0044] Further, if Figure 2 As shown, in this embodiment, a protective cover 33 is provided outside the transmitting end 321 and the receiving end 322 of the laser measuring instrument to prevent the laser measuring instrument from being affected or damaged by the outside.

[0045] like Figure 1 and Figure 2As shown, the main structure of the vehicle body frame 1 is generally a right-angled trapezoid structure, and the main structure includes multiple rods connected horizontally, vertically, and obliquely. A pusher 11 is provided at one end of the main structure of the vehicle body frame 1 to facilitate the staff to push the ingot measuring vehicle for movement. Two bearing seats 12 are also provided on the main structure of the vehicle body frame 1. A rotating shaft 13 is passed through between the two bearing seats 12. A through hole for the rotating shaft 13 to pass through is provided on the turning frame 2. The turning frame 2 is movably connected to the main structure of the vehicle body frame 1 through the rotating shaft 13, that is, the turning frame 2 can rotate around the rotating shaft 13, so that the turning frame 2 can be switched between the storage position and the object receiving position. Optionally, the storage position is the horizontal position, and the object receiving position is the vertical position. When in the vertical position, it is convenient for the ingot 8 to enter the turning frame 2 vertically. When in the horizontal position, it is convenient for transporting the ingot 8 and taking out the ingot 8 from the turning frame 2.

[0046] Optionally, a driving device 5 is further provided between the vehicle body frame 1 and the turning frame 2. The driving device 5 can drive the turning frame 2 to rotate around the rotating shaft 13 to switch the turning frame 2 between the vertical and horizontal positions. Specifically, as Figure 1 and Figure 2 shown, in this embodiment, the driving device 5 is an electric push rod. Among them, the fixed end of the electric push rod is movably connected to the vehicle body frame 1, and the telescopic end of the electric push rod is movably connected to the turning frame 2. Furthermore, when the push rod of the electric push rod extends, it can push the turning frame 2 to rotate from the horizontal position to the vertical position. When the push rod of the electric push rod retracts, it can pull the turning frame 2 to rotate from the vertical position to the horizontal position.

[0047] Driving the turning frame 2 to rotate by the electric push rod not only avoids the large amount of manpower required during the rotation of the turning frame 2, but also ensures the stability and safety of the ingot 8 during the rotation. It can be understood that in some other embodiments, the driving device 5 is not limited to an electric push rod, as long as it can drive the turning frame 2 to rotate around the rotating shaft 13. For example, it can also be a combination of a motor and a cam structure, and the rotation of the cam is used to switch the turning frame 2 between the vertical and horizontal positions.

[0048] As Figure 2 and Figure 3 shown, an installation frame 14 is provided on the vehicle body frame 1, and the positioning device 4 is provided on the installation frame 14. Optionally, the installation frame 14 is a "U" - shaped structure. Among them, the open end of the installation frame 14 is fixedly connected to the main structure of the vehicle body frame 1, and the closed end of the installation frame 14 is located below the main structure of the vehicle body frame 1. With such a setting, when the turning frame 2 rotates to the vertical position, the installation frame 14 can provide an avoidance space for the turning frame 2, thus avoiding affecting the rotation of the turning frame 2. The positioning device 4 is provided on the closed end of the installation frame 14, and the positioning device 4 can read the positioning marks on the ground.

[0049] Optionally, in this embodiment, positioning device 4 is a positioning sensor. When the positioning sensor detects a positioning mark placed on the ground in advance, it indicates that the crystal ingot measuring vehicle has moved to the target receiving position for the crystal ingot 8. This allows operators to quickly and accurately move the measuring vehicle to the target receiving position for the crystal ingot 8, reducing the time spent by operators positioning the measuring vehicle and improving receiving efficiency. It should be noted that the positioning mark is placed on the ground directly below the center of the receiving position for the crystal ingot 8.

[0050] like Figure 1 and Figure 2 As shown, casters 6 are provided at the bottom of the main structure of the vehicle frame 1, so that the crystal ingot measuring vehicle can be easily moved to transport the received crystal ingot 8 to any location, avoiding the situation where a large amount of manpower and material resources are required during the transportation of the crystal ingot 8. In addition, due to the clamping and limiting function of the first guide wheel 211 and the second guide wheel 221 in the turning frame 2, the stability and safety of the crystal ingot 8 during transportation can be ensured without any other operations.

[0051] Furthermore, a locking device is provided on any caster 6 of the vehicle frame 1. When the positioning device 4 senses the positioning mark on the ground, the locking device can promptly lock the caster 6, so that the crystal ingot measuring vehicle can accurately stop at the target receiving position of the crystal ingot 8, and then can accurately receive the crystal ingot 8 when the turning frame 2 is rotated to the vertical position.

[0052] like Figure 1 and Figure 2 As shown, the vehicle frame 1 is also provided with an electrical box 7, which houses a power supply and a PLC control system. The power supply is used to power the measuring instrument 32, the positioning device 4, the drive device 5, and the PLC control system. The PLC control system can run a control program, thereby controlling the operation of the measuring instrument 32, the positioning device 4, and the drive device 5 and achieving their respective functions. The control program is conventional and will not be described in detail here.

[0053] Specifically, the working process of the crystal ingot measuring vehicle provided by the present invention is as follows:

[0054] Move the crystal ingot measuring vehicle to the receiving position of the crystal ingot 8. When the positioning device 4 senses the positioning mark on the ground, it indicates that it has moved into position and locks the casters 6.

[0055] The PLC control system controls the turning frame 2 to rotate from a horizontal position to a vertical position;

[0056] The single crystal furnace is controlled to remove the crystal ingot 8 from the pulling chamber, causing the crystal ingot 8 to move downward and pass through the measuring assembly 3 into the turning rack 2. The measuring instrument 32 collects the diameter data of the crystal ingot 8 in real time until the crystal ingot 8 touches the bottom support 23. At this point, data collection is completed and the crystal ingot 8 has finished falling.

[0057] The connection between the crystal ingot 8 and the single crystal furnace is disconnected, and the turning frame 2 is controlled by the PLC control system to rotate from the vertical position to the horizontal position. Then the staff pushes the crystal ingot measuring vehicle with the crystal ingot 8 to the storage place of the crystal ingot 8.

[0058] The present invention provides a crystal ingot measuring vehicle. By arranging a measuring assembly 3 on a turning frame 2, the measuring assembly 3 can measure the full diameter of the crystal ingot 8 in real time during the process of taking the crystal ingot 8 out of the traction chamber and placing it into the turning frame 2, so that workers can analyze and adjust the process according to the real-time data. At the same time, by arranging a positioning device 4 on the vehicle body frame 1 to sense the positioning mark on the ground, the crystal ingot measuring vehicle can accurately stop at the target receiving position of the crystal ingot 8, and then can accurately receive the crystal ingot 8 when the turning frame 2 is rotated to the vertical position, thereby reducing the time spent by workers on positioning the crystal ingot measuring vehicle and improving the receiving efficiency.

[0059] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
