Description

Technical Field

[0001] This invention relates to the field of artificial lens testing, and more specifically to a device for testing the diameter of a crystal rod. Background Technology

[0002] Taking polycrystalline silicon rod growth as an example, the Siemens process for producing rod-shaped polycrystalline silicon involves introducing high-purity hydrogen (H2) and trichlorosilane (STC) at specific temperatures, pressures, and ratios into a sealed reduction furnace. Polycrystalline silicon is continuously reduced and deposited on the surface of a silicon core—a high-heat carrier heated to approximately 1080°C under high pressure. As the reaction continues, the amount of silicon deposited on the core increases, gradually thickening the silicon core to form a silicon rod. Once the silicon rod has grown to a suitable diameter after a certain time, the furnace is stopped, and the prepared silicon rod is removed.

[0003] Most polysilicon manufacturers use a silicon core production method where silicon core masterbatch is drawn into round silicon cores usable in a reduction furnace using a vertical zone melting method. During the drawing of round silicon cores, the diameter of the round silicon cores is controlled by adjusting the drawing speed and temperature. Therefore, multiple round silicon cores drawn at the same time often have different diameters. Even the same round silicon core may have uneven diameters within different length ranges. When the round silicon cores have uneven diameters, it is not easy to load them vertically in the reduction furnace due to the uneven thickness and point contact in the clamping plate. As the silicon rod grows thicker, the load-bearing center becomes eccentric, which can cause the furnace to tip over.

[0004] To address the aforementioned technical problems, those skilled in the art often manually measure the diameter of each round silicon core using handheld calipers. Furthermore, multiple measurements are taken at each silicon core to ensure its diameter meets usage requirements. However, this method is highly susceptible to human error, labor-intensive, and inefficient.

[0005] In summary, providing a device for detecting the diameter of crystal rods has been a long-standing technical challenge for those skilled in the art. Summary of the Invention

[0027] According to this application, an apparatus for detecting the diameter of a crystal rod is provided. The apparatus includes a crystal rod detection mechanism 3, which includes a linear module 305, a diameter collector disposed on a slider of the linear module 305, a crystal rod transfer mechanism disposed below the diameter collector, a crystal rod conveyor B304 disposed on one side of the crystal rod transfer mechanism, and a crystal rod support plate 301 disposed on the other side of the crystal rod transfer mechanism.

[0028] According to this application, by setting up a crystal rod sorting mechanism 1, it is possible to conveniently classify and store crystal rods 2 of different diameters, thereby improving the automation level of the device.

[0029] The specific structure of the preferred embodiments of this application will now be described in detail with reference to the accompanying drawings and examples. Example

[0030] The first embodiment is a structure that only includes the crystal rod detection mechanism 3; Figures 2 to 9 A schematic diagram is shown of an apparatus for detecting the diameter of a crystal rod according to a preferred embodiment of this application.

[0031] like Figures 2-5 As shown, according to one embodiment of this application, an apparatus for detecting the diameter of a crystal rod is provided. The apparatus includes a crystal rod detection mechanism 3, which includes a linear module 305, a diameter collector disposed on a slider of the linear module 305, a crystal rod transfer mechanism disposed below the diameter collector, a crystal rod conveyor B304 disposed on one side of the crystal rod transfer mechanism, and a crystal rod support plate 301 disposed on the other side of the crystal rod transfer mechanism.

[0032] Furthermore, the crystal rod conveyor B304 includes a conveying wheel 3042, a motor 3044, a conveying wheel mounting base 3045, a power transmission wheel, and a transmission component. The conveying wheel mounting bases 3045 are spaced at least two apart and are mounted on the frame 307. A conveying wheel 3042 is respectively arranged on one side of each conveying wheel mounting base 3045. The end of each conveying wheel 3042 is connected to a power transmission wheel. Multiple power transmission wheels are connected through a transmission component to realize power transmission. Any one of the power transmission wheels is connected to the motor 3044.

[0033] Furthermore, in order to ensure the transmission efficiency of the transmission components, when multiple conveyor wheel mounting seats 3045 are provided, a drive wheel is provided on at least one conveyor wheel mounting seat 3045.

[0034] Furthermore, such as Figure 2 As shown, in order to identify whether there are still crystal rods 2 on the conveyor wheel 3042, a sensor B308 is provided on the side of the conveyor wheel mounting base 3045, and the sensing head of the sensor B308 corresponds to the crystal rod 2.

[0035] In specific implementation, such as Figure 7 , 8 As shown, the power transmission wheel can be configured as a drive sprocket 3041, and the transmission component can be configured as a chain 3043. Three conveyor wheel mounting seats 3045 are spaced apart and arranged in a straight line on the frame 307. A conveyor wheel 3042 is mounted on one side of each conveyor wheel mounting seat 3045, and the end of each conveyor wheel 3042 is connected to a drive sprocket 3041. A drive sprocket 3046 is mounted on each of the conveyor wheel mounting seats 3045 at both ends. The three drive sprockets 3041 and two drive sprockets 3046 are connected by the chain 3043 to achieve power transmission. Any one of the drive sprockets 3041 or drive sprockets 3046 is connected to a motor 3044. In practice, to simplify the structure of the mechanism, connecting the drive sprocket 3046 to the motor 3044 is preferred. In practice, there can be one or two drive sprockets 3046.

[0036] Furthermore, the power transmission wheel can also be configured as a pulley, and the transmission component can be configured as a belt.

[0037] Furthermore, the crystal rod transfer mechanism includes a lifting mechanism, a sliding mechanism, a connecting rod 314, and a crystal rod support plate 315. Crystal rod supports 315 are respectively provided at both ends of the connecting rod 314. Each crystal rod support plate 315 has a downwardly recessed V-shaped groove 321 at both its front and rear ends. A lifting mechanism is provided below the connecting rod 314, and the slider of the sliding mechanism is connected to the lower part of the lifting mechanism. The fixed end of the sliding mechanism is mounted on the frame 307. Alternatively, the lower part of the connecting rod 314 is connected to the slider of the sliding mechanism, and the fixed end of the sliding mechanism is connected to the lifting mechanism, with the lifting mechanism mounted on the frame 307.

[0038] In specific implementation, such as Figure 6 As shown, the lifting mechanism is set as a lifting cylinder 312, and the sliding mechanism is set as a cylinder slide 313. In practice, the fixed part of the cylinder slide 313 is set on the frame 307, the lifting cylinder 312 is set on the slider of the cylinder slide 313, the connecting rod 314 is set on the lifting rod of the lifting cylinder 312, and crystal rod support plates 315 are respectively set at both ends of the connecting rod 314. Each crystal rod support plate 315 has a downwardly recessed V-shaped groove 321 for placing crystal rod 2 at both the front and rear ends. In practice, the lifting cylinder 312 is preferably a three-axis cylinder.

[0039] Furthermore, the lifting mechanism can be set as either a hydraulic cylinder or an electric push rod; the sliding mechanism can also be set as a sliding hydraulic cylinder.

[0040] Furthermore, such as Figure 2 , 4As shown in Figures 5 and 9, the upper surface of the crystal rod support 301 has an inclination angle of 1° to 10° with the horizontal plane. This allows the crystal rods 2 placed on the crystal rod support 301 to roll from the high end to the low end of the crystal rod support 301 by their own weight. When the inclination angle is less than 1°, the crystal rods 2 will not roll to the low end by themselves. When the inclination angle is greater than 10°, the rolling speed of the crystal rods 2 is too fast, which may cause the crystal rods 2 to break or become stuck due to deviation in the rolling position. In practice, the inclination angle is preferably 3°. The low end of the crystal rod support 301 is connected to the frame 307 and corresponds to the crystal rod transfer mechanism. In practice, a support frame 316 can be set on the frame 307, and the support frame 316 is connected to the low end of the crystal rod support 301. A crystal rod back baffle 320 is set at the low end of the crystal rod support 301.

[0041] When implementing, such as Figure 2 , 5 As shown, a crystal rod front baffle 319 can be provided above the outer side of the crystal rod rear baffle 320. The function of the crystal rod front baffle 319 is to prevent the crystal rod 2 from rolling forward after being lifted by the lifting cylinder 323. In practice, the crystal rod front baffle 319 can be provided on the gantry 318, and the gantry 318 is provided on the frame 307.

[0042] Furthermore, such as Figure 9 As shown, the low end of the crystal rod support 301 is provided with two lifting cylinders 323 at intervals. Lifting blocks 322 are respectively installed on the lifting rods of the two lifting cylinders 323. The lifting blocks 322 pass through the perforations on the outer side of the crystal rod rear baffle 320 on the crystal rod support 301 and move up and down within the perforations. In practice, the lifting blocks 322 are made of non-metallic material to avoid contamination caused by contact between the crystal rod 2 and metallic materials. In practice, the crystal rod support 301 can be configured as a single structure or a three-section structure. When configured as a three-section structure, as shown... Figure 2 As shown. Furthermore, to avoid direct contact between the crystal rod 2 and the crystal rod support plate 301, and to reduce the frictional resistance during the rolling of the crystal rod 2, multiple sliding plates 317 are spaced apart on the upper surface of the crystal rod support plate 301. These sliding plates 317 are also made of non-metallic material. Furthermore, crystal rod baffles 306 can be provided at both the left and right ends of the crystal rod support plate 301, specifically as shown... Figure 2 As shown.

[0043] Furthermore, such as Figure 2 , 3As shown in Figures 4 and 5, the linear module 305 is mounted on the frame 307. A camera mounting base 303 is mounted on the slider of the linear module 305. A diameter acquisition device is mounted on the camera mounting base 303. The diameter acquisition device is connected to a cable chain, and the lens of the diameter acquisition device corresponds to the crystal rod 2 on the crystal rod transfer mechanism. In practice, the diameter acquisition device is preferably a 3D camera 302, such as the LVM2520 3D camera manufactured by Yishi Technology (Ningbo) Co., Ltd.

[0044] Furthermore, such as Figure 2 , 3 As shown in Figure 4, a rotating seat 310 is provided on the frame 307, the rotating seat 310 is connected to the support arm 311, and a control box 309 is provided on the support arm 311.

[0045] In practical implementation, the following explanations are provided: I. The working position of crystal rod 2 is described as follows: 1. First station: The position of the first crystal rod 2 on the crystal rod tray 301, which is manually handled and loaded; 2. Second station: The position where the first crystal rod 2 on the crystal rod support plate 301 is lifted by the lifting cylinder 322 (denoted as cylinder Q1); 3. Third station: The position of crystal rod 2 below the detection head (3D camera 302), which is the detection station; 4. Fourth station: The position of crystal rod 2 on crystal rod conveyor B304.

[0046] II. Cylinder and Solenoid Valve Description 1. The lifting cylinder 322 is a dual-axis cylinder TN10*40S, two in number, numbered Q1, to lift the crystal rod 2 from the first station to the second station; the two lifting cylinders 322 operate simultaneously, controlled by solenoid valve F1 (model 4V110M5B). When no power is supplied, the cylinder rod retracts; when power is supplied, the cylinder rod extends. 2. The lifting cylinder 312 is a three-axis cylinder TCL40*25S, with one cylinder, numbered Q2, which lifts the crystal rod 2 to prepare for translation; it is controlled by solenoid valve F2 (model 4V11006B). When no power is applied, the cylinder rod retracts; when power is applied, the cylinder rod extends. 3. The cylinder slide 313 uses a STW32*100S slide cylinder, with a quantity of one, numbered Q3, to move the crystal rod 2 horizontally. It is controlled by the solenoid valve F3 (model 4V11006B). When no power is supplied, the slider on the cylinder slide 313 is closer to the linear module side; when power is supplied, the slider on the cylinder slide 313 is closer to the loading area side.

[0047] III. Sensor Placement Instructions 1. Four EE-SX672 modules are arranged on the linear module 305 (Yiheda YCTB22-40-3700-LH-75-D-4). They are numbered as follows: S1 (left limit position), S2 (left working position), S3 (right working position), and S4 (right limit position).

[0048] 2. Two E2K-X8E1 sensors are arranged on the ingot conveyor B304 (i.e., the fourth station), numbered S5 (in the middle of the ingot conveyor B304) and S6 (at the end of the ingot conveyor B304). S5 is used to detect whether there is ingot 2 in the fourth station; S6 is used to detect whether the fourth station has been cleared.

[0049] 3. An E2K-X8E1, numbered S8, is placed at the intermediate detection position (i.e., the third station) to detect whether there is a crystal rod 2 at the third station.

[0050] 4. An E2K-X8E1, numbered S9, is placed on the crystal rod tray 301 (i.e., the first station) to sense whether there is a crystal rod 2 at the first station; the cylinder Q1 that lifts the first crystal rod 2 has two sensors, with the cylinder rod extension position numbered S10 and the cylinder rod retraction position numbered S11.

[0051] 5. The lifting cylinder 312 (Q2) comes with two sensors: cylinder rod extension position number S12 and cylinder rod retraction position number S13.

[0052] 6. The cylinder slide 313 (Q3) comes with two sensors. The slide is numbered S14 on the side near the loading area and S15 on the side near the linear module.

[0054] IV. Motor Arrangement Instructions: 1. Linear module 305 is equipped with Huichuan motor MS1H1-75B30CB-A331Z to realize the movement of 3D camera 302. Motor number D1.

[0055] 2. The crystal rod conveyor B304 is powered by motor 3044, which is a Huichuan MS1H1-10B30CMS1H1 motor, used to transfer crystal rod 2 from the fourth station to the next station. Motor number D2.

[0056] V. Description of Testing Components: It consists of a 3D camera LVM2520, which is mounted on a linear module 305. The linear module 305 drives it to move left or right to complete the scanning and detection of the stationary crystal rod 2 at the third station. Example

[0057] The second embodiment is a structure in which a crystal rod sorting mechanism 1 is provided on one side of the crystal rod detection mechanism 3.

[0058] Combined with appendix Figure 1 , 10 As shown in Figures 11 and 12, the device for detecting the diameter of crystal rods includes a crystal rod detection mechanism 3. The crystal rod detection mechanism 3 includes a linear module 305, a diameter collector disposed on the slider of the linear module 305, a crystal rod transfer mechanism disposed below the diameter collector, a crystal rod conveyor B304 disposed on one side of the crystal rod transfer mechanism, and a crystal rod tray 301 disposed on the other side of the crystal rod transfer mechanism. A crystal rod sorting mechanism 1 is disposed on one side of the crystal rod conveyor B304.

[0059] Furthermore, such as Figure 1 , 10 As shown in Figures 11 and 12, the crystal rod sorting mechanism 1 includes a dual-axis robot 101, a crystal rod conveyor A105 disposed below the lifting arm of the dual-axis robot 101, and a crystal rod storage rack disposed on one side of the crystal rod conveyor A105 below the lifting arm of the dual-axis robot 101. The radial centers of the conveying wheel on the crystal rod conveyor A105 and the conveying wheel 3042 on the crystal rod conveyor B304 are arranged on the same straight line.

[0060] Furthermore, the crystal rod storage rack includes a sorting rack 108 and crystal rod storage layers. At least two crystal rod storage layers are spaced vertically on the sorting rack 108. The upper surface of each crystal rod storage layer has an inclination angle of 1° to 10° with the horizontal plane. This allows the crystal rods 2 placed on the storage layers to roll from the higher end to the lower end of the storage layer by their own weight. When the inclination angle is less than 1°, the crystal rods 2 will not roll downwards on their own. When the inclination angle is greater than 10°, the rolling speed of the crystal rods 2 is too fast, which may cause the crystal rods 2 to break or become stuck due to misalignment. In practice, the inclination angle is preferably 3°, and the higher end of each crystal rod storage layer corresponds to the crystal rod conveyor A105.

[0061] When implementing, such as Figure 9 As shown, the crystal rod storage layer is set to four layers, from bottom to top: storage layer A109, storage layer B110, storage layer C111 and storage layer D112. Each layer stores crystal rods 2 of different diameters after testing.

[0062] Furthermore, the dual-axis robot 101 is mounted on the column 103. The lower end of the lifting arm of the dual-axis robot 101 is connected to the connecting plate 102, and hooks 104 are respectively provided below both ends of the connecting plate 102. In implementation, the dual-axis robot 101 can be a Tianjin Jinyang XZ-DC4MC0-F3-X550L40-Z400L10 dual-axis robot, or a two-degree-of-freedom manipulator of the same type from other manufacturers.

[0063] Furthermore, the crystal rod conveyor A105 includes a conveying wheel, a motor, a conveying wheel mounting base, a power transmission wheel, and a transmission component. The conveying wheel mounting bases are spaced at least two apart and are mounted on a fixed frame 106. A conveying wheel is provided on one side of each conveying wheel mounting base, and the end of each conveying wheel is connected to a power transmission wheel. Multiple power transmission wheels are connected through a transmission component to transmit power, and any one of the power transmission wheels is connected to a motor.

[0064] Furthermore, when multiple conveyor wheel mounting seats are provided, a drive wheel is provided on at least one conveyor wheel mounting seat.

[0065] Furthermore, the conveyor wheel mounting base is mounted on the fixed frame 106, and a sensor A107 is mounted at the end of the fixed frame 106.

[0066] In practice, the power transmission wheel can be configured as a sprocket or a pulley, and the transmission component can be configured as a chain or a belt.

[0067] In practice, the specific structure of the crystal rod conveyor A105 is consistent with that of the crystal rod conveyor B304.

[0068] In practical implementation, the following explanations are provided: I. The working position of crystal rod 2 is described as follows: 1. Fifth station: The position of crystal rod 2 on crystal rod conveyor A105; 2. Sixth station: The initial position of crystal rod 2 in storage area A; 3. Seventh station: The initial position of crystal rod 2 in storage area B; 4. Eighth station: The initial position of crystal rod 2 in the C storage area; 5. Ninth station: The initial position of crystal rod 2 in storage area D.

[0069] II. Sensor Arrangement Instructions 1. A sensor A107, model E2K-X8E1, numbered S7, is installed at the end of the crystal rod conveyor A105 (i.e., the fifth station). S7 is used to detect whether there is a crystal rod 2 at the fifth station. 2.

[0071] 4. The storage area for the cuttable beam crystal rod 2, also known as area C, has an E2K-X8E1, numbered S18, which senses whether the storage area C is full of crystal rod 2.

[0072] 5. The storage area for scrapped crystal rods is area 2, also known as area D. There is an E2K-X8E1, numbered S19, which senses whether storage area D is full of crystal rod 2.

[0073] 6. A dual-axis robot 101 transfers crystal rod 2 from the fifth station to four stations (sixth, seventh, eighth, and ninth stations). Three sensors are arranged on the X-axis, numbered S20 (front limit position), S21 (origin position), and S22 (rear limit position). Three sensors are arranged on the Z-axis, numbered S23 (upper limit position), S24 (origin position), and S25 (lower limit position). The robot stops at its origin position, with S21 and S24 both ON.

[0074] 7. All sensors are ON when there is a signal and OFF when there is no signal.

[0075] III. Motor Layout Instructions 1. The crystal rod conveyor A105 is powered by a motor, specifically the Huichuan MS1H1-10B30C MS1H1 motor, which transports crystal rod 2 from the fourth station to the next station. The motor number is D3.

[0076] 2. The dual-axis robot 101, which takes the crystal rod 2 to four preset positions, consists of Huichuan motor MS1H1-40B30CB-A334Z (numbered D4) controlling the X-axis position and Huichuan motor MS1H1-20B30CB-A334Z (numbered D5) controlling the Z-axis position.

[0077] In conjunction with the first and second embodiments, the specific operational procedures and electrical requirements of this application are as follows: 1. All descriptions below are represented by numbers.

[0078] 2. The equipment is equipped with red, yellow, and green alarm lights to indicate its operating status. The alarm lights cannot display two colors simultaneously.

[0079] 3. An emergency stop button is provided. In case of an emergency, pressing this button will cut off the power to the equipment.

[0080] 4. Configure the power-on and power-off buttons.

[0081] 5. Press the start button to automatically enter the continuous working program.

[0082] 6. Continuous Working Procedure: The continuous working process consists of three independent sub-processes, described as follows: 6.1, 6.2, and 6.3.

[0083] 6.1 Lift the crystal ingot 2 from the first station to the second station. Then, move the crystal ingot 2 from the second station to the third station, and simultaneously move the crystal ingot 2 from the third station to the fourth station.

[0084] 6.1.1 With all solenoid valves de-energized, the S9 signal is checked. If it is OFF, a yellow alarm light will illuminate on the screen, indicating "Please Load Material," and the system will wait for the worker to load the material. After loading, S9 will turn ON, the green light will illuminate, and the alarm message on the screen will disappear.

[0085] 6.1.2 If S9 is ON, then detect S5, S6, S10, S11, S12, S13, S14, and S15 as ON, and then wait for 0.2 seconds; F1 is powered on, and after detecting S10 as ON and S11 as OFF, F3 is powered on, and after detecting S14 as ON and S15 as OFF, F2 is powered on, and after detecting S12 as ON and S13 as OFF, F3 is powered off; after detecting S14 as OFF and S15 as ON, F2 is powered off; after detecting S12 as OFF and S13 as ON, F1 is powered off, and wait for 0.1 seconds.

[0086] 6.1.3 After detecting that S8 is ON, the detection begins.

[0087] 6.1.3.1 Determine the stopping position of the measuring component. If S2 is ON, the measuring component is at the left initial position, then proceed to step 7.1.3.2. If S3 is ON, the measuring component is at the right initial position, then proceed to step 7.1.3.3.

[0088] 6.1.3.2 Start D1 and rotate from left to right, increasing the speed to the predetermined 750 rpm within 8 mm. When S2 turns OFF, notify the detection software to start the measurement. Continue until S3 turns ON, notifying the measuring component to stop the measurement. At the same time, D1 starts to decelerate, reducing the speed to 50 rpm within about 8 mm, and continues at this speed until it stops at the recorded right initial position.

[0089] 6.1.3.3 Start D1 and rotate from right to left, increasing the speed to the predetermined 750 rpm within 8 mm. When S3 turns OFF, notify the detection software to start the measurement. Continue until S2 turns ON, notifying the measuring component to stop the measurement. At the same time, D1 starts to decelerate, reducing the speed to 50 rpm within about 8 mm, and continues at this speed until it stops at the recorded left initial position.

[0090] 6.1.3.4 The measurement software calculates the measurement results and transmits them to the PLC.

[0091] 6.1.4 Jump to 6.1.1 to begin the lifting, handling and testing of the next crystal rod.

[0092] 6.2 Crystal rod transfer: Transfer the crystal rod from the fourth station to the fifth station. After determining that S5 is ON and S7 is OFF, start D2 and D3. When the crystal rod is transferred to the fifth station, D2 and D3 stop.

[0093] 6.3 Crystal rod transfer: Transfer the crystal rod from the fifth station to the sixth to ninth stations.

[0094] 6.3.1 If S7 is detected as ON, according to the results given by the measurement software, those with larger average acceptable dimensions are classified as Class A, those with smaller average acceptable dimensions as Class B, those suitable for cutting crossbeams as Class C, and those that are scrapped as Class D. Transfer the crystal rods from station 4 to the corresponding stations 6 through 9. Specifically, when performing the following actions, S21 and S23 must be checked to be ON each time; otherwise, a message will pop up on the screen indicating that the robot is not at its origin. Regardless of the reason, if S20, S22, S23, or S25 is detected as ON, a message will pop up on the screen indicating that the robot has reached its limit position; please troubleshoot the problem.

[0095] 7. If it is Class A, the crystal ingot in station 5 needs to be transferred to station 6. At this time, if S16 is ON, a message will pop up on the screen asking to clear the crystal ingot in area A, and the yellow alarm light will illuminate. The system will enter a waiting state until S16 is detected as OFF. The message will then automatically disappear, and the yellow light will turn off while the green light illuminates. Then, execute the following steps in sequence: D5 rotates clockwise 6 times (Z-axis descends 60mm), then D4 rotates clockwise 0.875 times (X-axis advances 35mm), then D5 rotates counterclockwise 6 times (Z-axis rises 60mm), then D4 rotates clockwise 4.6 times (X-axis advances 184mm), then D5 rotates clockwise 38 times (Z-axis descends 380mm). At this point, the crystal ingot is placed at the end of area A. The crystal ingot is released from the hook's constraint and rolls down by its own weight until it encounters an obstacle. Then D5 reverses 38 times (Z-axis rises 380mm), then D4 reverses 5.475 times (X-axis retreats 219mm); at this point, the robotic arm returns to the origin, and S21 and S24 are both ON, preparing for the next crystal rod pick-up and drop.

[0096] 8. If it is type B, the crystal ingot at station 5 needs to be transferred to station 7. If S17 is ON at this time, a message will pop up on the screen asking to clear the crystal ingot in area B, and the yellow alarm light will illuminate. The system will enter a waiting state until S17 is detected as OFF. The message will then automatically disappear, and the yellow light will turn off while the green light illuminates. Then, execute the following steps in sequence: D5 rotates clockwise 6 times (Z-axis descends 60mm), then D4 rotates clockwise 0.875 times (X-axis advances 35mm), then D5 rotates counterclockwise 6 times (Z-axis rises 60mm), then D4 rotates clockwise 7.1 times (X-axis advances 284mm), then D5 rotates clockwise 26.5 times (Z-axis descends 265mm). At this point, the crystal ingot is placed at the end of area B. The crystal ingot is released from the hook's constraint and rolls down by its own weight until it encounters an obstacle. Then D5 reverses 26.5 revolutions (Z-axis rises 265mm), then D4 reverses 7.975 revolutions (X-axis retreats 319mm); at this point, the robotic arm returns to the origin, and S21 and S24 are both ON, preparing for the next crystal rod pick-up and drop.

[0097] 9. If it is a Class C crystal, the crystal rod at station 5 needs to be transferred to station 8. If S18 is ON at this time, a message will pop up on the screen asking to clear the crystal rod in area C, and the yellow alarm light will illuminate. The system will enter a waiting state until S18 is detected as OFF. The message will then automatically disappear, and the yellow alarm light will turn off while the green alarm light illuminates. Next, execute the following steps in sequence: D5 rotates clockwise 6 times (Z-axis descends 60mm), then D4 rotates clockwise 0.875 times (X-axis advances 35mm), then D5 rotates counterclockwise 6 times (Z-axis rises 60mm), then D4 rotates clockwise 9.6 times (X-axis advances 384mm), then D5 rotates clockwise 15 times (Z-axis descends 150mm). At this point, the crystal rod is placed at the end of area C, freed from the hook's constraint, and rolls downwards under its own weight until it encounters an obstacle. Then D5 reverses 15 revolutions (Z-axis rises 150mm), then D4 reverses 10.475 revolutions (X-axis retreats 419mm); at this point, the robotic arm returns to the origin, and S21 and S24 are both ON, preparing for the next crystal rod pick-up and drop.

[0098] 10. If it is a Class D crystal, the crystal rod at station 5 needs to be transferred to station 9. If S19 is ON at this time, a message will pop up on the screen asking to clear crystal rod 2 in zone D, and the yellow alarm light will illuminate. The system will enter a waiting state until S19 is detected as OFF. The message will then automatically disappear, and the yellow light will turn off while the green light illuminates. Next, execute the following steps in sequence: D5 rotates clockwise 6 times (Z-axis descends 60mm), then D4 rotates clockwise 0.875 times (X-axis advances 35mm), then D5 rotates counterclockwise 6 times (Z-axis rises 60mm), then D4 rotates clockwise 12.1 times (X-axis advances 484mm), then D5 rotates clockwise 3.5 times (Z-axis descends 35mm). At this point, the crystal rod is placed at the end of zone D, freed from the hook's constraint, and rolls downwards under its own weight until it encounters an obstacle. Then D5 reverses 3.5 revolutions (Z-axis rises 35mm), then D4 reverses 12.975 revolutions (X-axis retreats 519mm); at this point, the robotic arm returns to the origin, and S21 and S24 are both ON, preparing for the next crystal rod pick-up and drop.
