[0116] The second pulley assembly 1482 moves the two support plates 1483 closer or further apart, adapting to graphite boats of different lengths and improving applicability.

[0117] like Figures 17-18 As shown, the conveying device 15 includes a Y-axis belt-driven servo module 151. The Y-axis belt-driven servo module 151 includes a third servo motor 153, a third pulley assembly 154, and two tracks. The third servo motor 153 drives and connects to the third pulley assembly 154. A Y-axis moving seat 152 is slidably arranged on the track of the Y-axis belt-driven servo module 151. A Z-axis lifting rail mechanism 155 is arranged on the Y-axis moving seat 152. An X-axis support arm 156 is arranged at the lower end of the Z-axis lifting rail mechanism 155. A gripper assembly 157 is symmetrically arranged on the X-axis support arm 156.

[0118] The gripper assembly 157 is driven by a cylinder to grip the graphite boat, then lifted by the Z-axis lifting rail mechanism 155, and then moved by the Y-axis belt-driven servo module 151.

[0119] The working principle before the improvement: The external feeder sends the graphite boat to the loading and unloading device, which transports the graphite boat to the first buffer device. Then, the conveying device transports it to the tension correction device for tension correction. During the tension correction of the first graphite boat, the second graphite boat is sent to the first buffer device by the loading and unloading device for buffering. After the first graphite boat completes the correction, the conveying device transports the corrected first graphite boat to the detection device for detection. During the detection, the conveying device transports the second graphite boat buffered in the first buffer device to the tension correction device for tension correction. After the first graphite boat is detected, it is transferred by the conveying device to the second buffer device. Then, the second corrected graphite boat is transported to the detection device for detection. Then, the third graphite boat is fed to the tension correction device. Then, the conveying device puts the first graphite boat on the second buffer device into the first buffer device and then unloads it.

[0120] During this process, graphite boats that fail the inspection are transported again by the conveying device to the tension correction device. Graphite boats that fail the correction multiple times are marked and sent to the first buffer device for unloading. The first buffer device uses its own stacking function to buffer the graphite boats that have been inspected and those that are to be corrected.

[0121] The first buffer device, in conjunction with the second buffer device, buffers the graphite boat during the tightening and testing processes, ensuring smooth operation during these processes and keeping the tightening correction device and testing device constantly working.

[0122] The entire process is highly automated, which greatly improves the efficiency of graphite boat calibration. The overall structure is compact, and detection and calibration are carried out simultaneously, further improving the calibration efficiency.

[0123] The working process of the above-mentioned conveying device is usually serial, that is, the conveying device transfers the graphite boat from the previous process to the temporary storage device, and after the calibration is completed, the same conveying device transfers the graphite boat to the next process. This serial working mode has obvious bottlenecks: the conveying device needs to frequently go back and forth during the transfer process, resulting in low equipment utilization.

[0124] Therefore, as shown in Figure 5 、 Figure 19 In order to reduce the equipment waiting time and improve the equipment utilization, the conveying device and the temporary storage device are added on this basis in one embodiment, specifically, the upper and lower devices 11, the first buffer device 12, the second buffer device 16, the tension correction device 13, the detection device 14, and the third buffer device 17 are sequentially arranged from left to right in the case 10. The conveying device specifically includes: a frame, at least two sliders 159, at least two motors 1510, and at least two belts. The frame is provided with two second sliding rails along the length direction thereof. The two sliders 159 are slidingly arranged on the two second sliding rails and can move along the length direction of the second sliding rails. Each slider 159 has a clamping assembly 1511, a lifting rail 158, and a grabbing assembly.

[0125] The two belts are arranged along the length direction of the two second sliding rails, and the two sliders 159 are connected to the two belts one by one through the clamping assembly 1511. The two motors 1510 are drivingly connected to the two belts, and each motor 1510 is used to drive the corresponding belt. Each belt is used to drive the corresponding slider 159 to move on the second sliding rail. The lifting rail 158 of each slider 159 is arranged in the vertical direction, and the lifting rail 158 is connected to the grabbing assembly 6 below. The grabbing assembly is used to grab the graphite boat.

[0126] Improved working principle: the first graphite boat and the second graphite boat are sent to the loading and unloading device by the external loading machine, at this time, the first carrying device carries the first graphite boat to the tension correction position for tension correction, and carries the second graphite boat to the second buffer device for temporary storage, at this time, the loading device sends the third graphite boat and the fourth graphite boat, then the second carrying device carries the first graphite boat corrected to the detection station for detection, the first carrying device carries the third graphite boat and the fourth graphite boat in the loading and unloading device to the first buffer device and the second buffer device for buffering, the second carrying device carries the first graphite boat detected to the third buffer device for buffering, and carries the second graphite boat corrected to the detection station for detection, the second carrying device carries the first graphite boat from the third buffer device to the first buffer device, at the same time, the loading and unloading device sends the fifth graphite boat and the sixth graphite boat, the first carrying device carries the third graphite boat from the first buffer device to the tension correction position for tension correction, the second carrying device carries the second graphite boat detected to the third buffer device for temporary storage, the first carrying device carries the third graphite boat corrected to the detection station for detection, and carries the fourth graphite boat from the second buffer device to the tension correction position for correction, the second carrying device carries the second graphite boat to the first buffer device for buffering, and the first carrying device carries the first graphite boat and the second graphite boat in the first buffer device to the loading and unloading device for unloading.

[0127] As shown in Figure 17 , the existing technology grabbing assembly 157 is pushed by a cylinder to grab the graphite boat, the stroke of the cylinder is limited, and it is difficult to meet the grabbing demand of graphite boats of different specifications, especially when the size of the graphite boat changes greatly, the grabbing device pushed by the cylinder often cannot be compatible with graphite boats of different sizes.

[0128] Therefore, as shown in Figure 6As shown, in order to be compatible with graphite boats of different specifications, in an embodiment, the grabbing assembly 6 includes a support arm 601, a first clamping piece 602, a second clamping piece 603, and a belt drive assembly 7. The support arm 601 is provided with a first sliding rail along the length direction. The first clamping piece 602 and the second clamping piece 603 each have a clamping portion 5, a supporting portion 8, and a hanging portion 9. The first clamping piece 602 and the second clamping piece 603 are arranged at the two ends of the support arm 601, and the clamping portion 5 of the first clamping piece 602 and the second clamping piece 603 is slidingly arranged on the sliding rail. The supporting portion 8 of the first clamping piece 602 and the second clamping piece 603 is used to support the boat foot of the graphite boat. The second belt moving servo module 7 is arranged along the length direction of the support arm 601. The hanging portion 9 of the first clamping piece 602 is connected to the first side of the belt, and the hanging portion 9 of the second clamping piece 603 is connected to the second side of the belt. The belt moving servo module is used to drive the hanging portions of the first clamping piece 602 and the second clamping piece 603 to move relatively along the length direction. The first side of the belt is the upper belt, and the second side of the belt is the lower belt.

[0129] Further, the belt drive assembly 7 includes a fourth servo motor, a driving wheel, and a driven wheel. The fourth servo motor is arranged on one side of the support arm. The driving wheel is in transmission connection with the driving shaft of the fourth servo motor. The driven wheel is arranged on the other side of the support arm 1 and is in transmission connection with the driving wheel through a belt. The fourth servo motor and the belt cooperate with each other, and have the characteristics of stable transmission, low noise, high positioning accuracy, and large stroke range. Through the precise control of the fourth servo motor, the position accuracy of the first clamping piece and the second clamping piece can be adjusted. At the same time, the belt transmission can meet the demand of large stroke, so as to be compatible with the grabbing of graphite boats of multiple specifications.

[0130] Through the precise control of the fourth servo motor in the belt drive assembly, the position accuracy of the first clamping piece and the second clamping piece can be adjusted. At the same time, the synchronous belt transmission in the belt assembly can meet the demand of large stroke, so as to be compatible with the grabbing of graphite boats of multiple specifications, and significantly improve the production efficiency and the versatility of the equipment.

[0131] As can be seen from the above, through the parallel working mode of the double sets of carrying devices and the temporary storage device, the improved scheme can significantly improve the transfer efficiency and temporary storage capacity of the graphite boat. Specifically, the newly added carrying device can work cooperatively with the original carrying device and be responsible for the transfer of graphite boats between different processes, thereby reducing the waiting time of the equipment and improving the utilization rate of the equipment. At the same time, the newly added temporary storage device can store more graphite boats, providing more buffer space for calibration and subsequent processes, improving the production capacity, and also enhancing the stability and reliability of the equipment.
