[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] As described in the background, when feeding the secondary chamber of the single crystal furnace, in the existing solutions, the positioning accuracy requirements for the hanging device during the hanging and mating process are relatively high. When the automatic guided vehicle transports the hanging device to the position of the secondary chamber, if the hanging device does not meet the preset positioning accuracy requirements of being aligned with the central axis of the weight, for example, the central axis of the hanging device is not aligned with the central axis of the weight, it will cause the hanging device and the weight to fail to achieve hanging, or even if the hanging is successful, due to the deviation, the hanging will be insecure and there is a risk of falling off and separating. To better solve this problem, the researchers in this application propose a hanging device in which the size of the engaging area can be dynamically enlarged or reduced, thereby reducing the positioning accuracy requirements when the engaging module of the hanging device and the support seat of the weight are engaged. Even if the central axis of the hanging device is deviated from the central axis of the weight, it does not affect the achievement of hanging, and at the same time, the reliability of the hanging device during the hanging process is also improved.

[0033] As Figure 1 shown, Figure 1This is a schematic structural diagram of the engaging state of the hanging device in an embodiment of the present application. In this embodiment, the hanging device includes: a support base 100 and an engaging module 200. The support base 100 is arranged in the weight of the single crystal furnace. Specifically, the support base 100 is connected to the bottom of the weight, that is, the support base 100 can move up and down as the weight rises and falls. The shape of the support base 100 can be a regular rectangle or a cone, and the support base 100 and the weight can be connected by, for example, a threaded connection; the engaging module 200 can be connected to the feeding device. The bottom of the engaging module 200 is connected to the feeding device. For example, the feeding device is connected to the engaging module 200 by a threaded connection. By dynamically adjusting the size of the engaging area 221 in the engaging module 200, the support base 100 can be restricted in the engaging area 221 or moved out of the engaging area 221, that is, the dissociation or engagement of the engaging component 220 and the support base 100 is realized; since the size of the engaging area 221 can be dynamically controlled and adjusted, the positioning accuracy requirement of the hanging device during the hanging process can be reduced. When the engaging module 200 is fixedly engaged with the support base 100, the weight drives the hanging device, and the hanging device drives the feeding device to move up and down, thereby realizing the feeding process to the single crystal furnace.

[0034] Specifically, the support base 100 is connected to the bottom of the weight; the engaging module 200 includes a pressure plate assembly 210 and an engaging component 220. The bottom of the pressure plate assembly 210 is connected to the feeding device. The engaging component 220 forms an engaging area 221 for accommodating the support base 100. The pressure plate assembly 210 is arranged at the bottom of the engaging area 221 and controls the expansion of the engaging area 221 by rotating in the first direction and controls the reduction of the engaging area 221 by rotating in the second direction opposite to the first direction, thereby realizing the dissociation or engagement of the engaging component and the support base.

[0035] In this embodiment, the support base 100 is pre-connected to the weight, and at the same time, a feeding device is arranged at the bottom of the pressure plate assembly 210 of the engaging module 200. For example, the feeding device is arranged at the bottom of the pressure plate assembly 210 by a threaded connection. When the engaging module 200 is dissociated from the support base 100, the engaging component 220 in the engaging module 200 rotates in the first direction, as shown in Figure 1 the direction pointed by the arrow a1. At this time, the engaging component 220 moves in the b1 direction, and the engaging area 221 formed by the engaging component 220 expands, and the support base 100 can move out of the engaging area 221; when the engaging module 200 is engaged with the support base 100, the engaging component 220 in the engaging module 200 rotates in the second direction opposite to the first direction, as shown in Figure 2In the direction pointed by arrow a2, at this time, the engaging component 220 moves in the b2 direction, and the engaging area 221 formed by the engaging component 220 shrinks, and the support base 100 engages with the engaging area 221. In this embodiment, by dynamically adjusting the size of the engaging area 221, the accuracy requirement for the alignment of the central axis of the plumb bob and the central axis of the hanging device in the existing solution is preferably solved.

[0036] It should be noted that when the support base 100 is restricted in the engaging area 221, that is, when the support base 100 moves upward following the plumb bob, the support base 100 moves in the direction away from the engaging area 221. At this time, the engaging component 220 can apply at least a pressing force to the upper side of the support base 100, so as to restrict the support base 100 from disengaging from the engaging area 221 formed by the engaging component 220.

[0037] Further, in one embodiment, reference may be made to Figure 1 and Figure 3 As shown, the pressing disc assembly 210 includes a first pressing disc 211 and a second pressing disc 212 arranged coaxially. The second pressing disc 212 is rotatably arranged on the upper side of the first pressing disc 211; the second pressing disc 212 is provided with a plurality of arc-shaped grooves 2121. The distance from the first end of each arc-shaped groove 2121 to the central axis of the second pressing disc 212 is less than the distance from the second end of the arc-shaped groove 2121 to the central axis of the second pressing disc 212, and the second end is located on the upstream side of the first end along the first direction of rotation. That is to say, the first end of the arc-shaped groove 2121 is close to the center of the second pressing disc 212, the second end is close to the edge of the second pressing disc 212, and the second end is located on the upstream side of the first end along the first direction of rotation; the engaging component 220 is at least provided with a plurality of rotating parts 222 inserted into the plurality of arc-shaped grooves 2121. When the second pressing disc 212 rotates relative to the first pressing disc 211, the rotating parts 222 slide along the arc-shaped grooves 2121 to realize the radial movement of the rotating parts 222, driving the reduction or expansion of the engaging area 221 of the engaging component 220.

[0038] In this embodiment, the action of one of the rotating parts 222 and the arc groove 2121 corresponding to the rotating part 222 is taken as an example for explanation, and the action principles of other rotating parts 222 are similar. Specifically, when it is necessary to expand the engaging area 221 formed by the engaging assembly 220, the second pressure plate 212 rotates relative to the first pressure plate 211 around the first direction, and at this time, the rotating part 222 of the engaging assembly 220 slides from the first end to the second end of the arc groove 2121. It should be noted that under the constraint of the arc groove 2121, the rotating part 222 moves in the radial direction away from the central axis of the second pressure plate 212; when it is necessary to reduce the engaging area 221 formed by the engaging assembly 220, the second pressure plate 212 rotates relative to the first pressure plate 211 around the second direction opposite to the first direction, and at this time, the rotating part 222 of the engaging assembly 220 slides from the second end to the first end of the arc groove 2121. Similarly, under the constraint of the arc groove 2121, the rotating portion 222 moves in the radial direction close to the central axis of the second pressure plate 212. In this embodiment, the arc groove 2121 in the second pressure plate 212 drives the movement of the rotating portion 222 in the engaging assembly 220, and the engaging assembly 220 moves away from or close to the central axis of the second pressure plate 212, thereby controlling the expansion or contraction of the middle engaging area 221.

[0039] Furthermore, in one embodiment, a plurality of arcuate grooves 2121 are provided on the second pressure plate 212, and the connecting lines of all the first ends and the connecting lines of all the second ends of the plurality of arcuate grooves 2121 form concentric circles of the second pressure plate 212, the radius of the circle where all the first ends are located is smaller than the radius of the circle where all the second ends are located, and the radius of the circle where all the second ends are located is smaller than the radius of the second pressure plate 212.

[0040] In this embodiment, the researchers formed concentric circles by connecting the first ends of the plurality of arc grooves 2121 provided in the second pressure plate 212 and the second ends thereof, so that each rotating part 222 in the clamping assembly 220 can move synchronously in the corresponding arc groove 2121. The reason why the radius of the circle where all the first ends of the plurality of arc grooves 2121 are located is smaller than the radius of the circle where the second ends are located is that when the rotating part 222 in the clamping assembly 220 slides from the first end to the second end of the arc groove 2121, the clamping area 221 in the clamping assembly 220 is in an expanded state, and the clamping assembly 220 moves in a radial direction away from the central axis of the second pressure plate 212, so the radius of the circle where all the first ends are located needs to be smaller than the radius of the circle where the second ends are located. At the same time, in order to prevent the rotating part 222 from detaching from the arc groove 2121, the radius of the circle where the second end is located needs to be smaller than the radius of the second pressure plate 212.

[0041] In one embodiment, see Figure 3As shown, the first pressure plate 211 is provided with a plurality of linear sliding grooves 2111 extending along the radial direction of the first pressure plate 211. The engaging assembly 220 is at least provided with a plurality of sliding parts 223 that move radially within the plurality of linear sliding grooves 2111. Each rotating part 222 protrudes upward from the upper surface of each sliding part 223 and is inserted into the arc-shaped groove 2121 on the second pressure plate 212.

[0042] In this embodiment, when the rotating part 222 in the engaging assembly 220 slides relative to the arc-shaped groove 2121, the sliding part 223 slides relative to the linear sliding groove 2111. When the rotating part 222 slides from the first end to the second end of the arc-shaped groove 2121, that is, when it is away from the center of the second pressure plate 212, the sliding part 223 slides along the linear sliding groove 2111 from the center of the first pressure plate 211 radially towards the edge, thereby driving the engaging assembly 220 away from the center and expanding the engaging area 221; when the rotating part 222 slides from the second end to the first end of the arc-shaped groove 2121, that is, when it is towards the center of the second pressure plate 212, the sliding part 223 slides along the linear sliding groove 2111 from the edge of the first pressure plate 211 radially towards the center, thereby driving the engaging assembly 220 to contract towards the center and reducing the engaging area 221.

[0043] The sliding part 223 is a plate-like structure arranged in the linear sliding groove 2111 and can slide along the linear sliding groove 2111. The sliding part 223 extends along the extending direction of the linear sliding groove 2111. The rotating part 222 is arranged at the end of the sliding part 223 close to the center of the first pressure plate 211. The rotating part 222 is a protrusion protruding upward from the upper surface of the sliding part 223. The rotating part 222 protrudes upward beyond the limitation of the linear sliding groove 2111 and can be inserted into the arc-shaped groove 2121 provided on the second pressure plate 212 located above the first pressure plate 211 to enable the rotating part 222 to slide in the arc-shaped groove 2121.

[0044] In one embodiment, referring to Figure 1 and Figure 3 As shown, the engaging assembly 220 includes a plurality of engaging members 224. The plurality of engaging members 224 extend vertically and are circumferentially spaced on the first pressure plate 211 and enclose the engaging area 221. The bottom end of each engaging member 224 is vertically connected to one end of the sliding part 223 away from the central axis of the first pressure plate 211. The top end of each engaging member 224 is provided with an engaging hook 2241. The top of the support base 100 is provided with an engaging groove 110.

[0045] In this embodiment, multiple engaging members 224 in the engaging assembly 220 are evenly spaced along the circumference of the first pressure plate 211 and jointly enclose a deformable engaging area 221. The bottom end of each engaging member 224 is vertically connected to the sliding portion 223, which is slidably engaged with the linear slideway 2111 in the first pressure plate 211 to ensure that the engaging member 224 is guided and restricted during the process of approaching or departing from the axis center of the first pressure plate 211. The top end of each engaging member 224 is provided with an engaging hook 2241, and an engaging groove 110 is provided at the top of the support base 100, so as to realize the engagement between the engaging hook 2241 and the engaging groove 110. When the engaging area 221 shrinks, at this time the support base 100 moves upward. Since the support base 100 is located in the engaging area 221, the edge of the engaging groove 110 provided at the top of the support base 100 can be pressed by the engaging hook 2241, realizing a reliable suspension connection between the engaging module 200 and the support base 100, thereby realizing a reliable connection between the weight and the hanging device. When the weight drives the hanging device to rise, the engaging member 224 of the engaging module is suspended at the upper end of the support base 100 through the engaging hook 2241, preventing the support base 100 from disengaging from the engaging area 221, thereby realizing effective clamping and fixing of the support base 100.

[0046] Through this design, when the second pressure plate 212 rotates relative to the first pressure plate 211, multiple engaging members 224 can be driven by the arc-shaped groove 2121 to approach or depart from the central axis of the first pressure plate 211 synchronously, thereby dynamically adjusting the size of the engaging area 221. When the engaging area 221 shrinks, the support base 100 is reliably restricted within the engaging area 221; when the engaging area 221 expands, the support base 100 can smoothly enter or exit the engaging area 221. In addition, in this embodiment, this arrangement of multiple engaging members 224 enables the engaging assembly 220 to distribute the acting force more evenly to the engaging hooks 2241 of each engaging member 224 when engaging and fixing with the support base 100.

[0047] In this embodiment, the number of the engaging members 224 in the engaging assembly 220 can be 3 or more, and can be specifically determined according to the size of the support base 100. When the number of the engaging members 224 is 3, the number of the linear slideways 2111 and the number of the arc-shaped grooves 2121 are also 3.

[0048] In one embodiment, as shown in Figure 3 and Figure 4 it can be seen that the engaging hook 2241 is located within the engaging area 221 and opens downward, the engaging groove 110 opens upward, and the engaging hook 2241 is hung on the side wall of the engaging groove 110.

[0049] In this embodiment, when the engaging area 221 shrinks, the engaging hook 2241 also moves closer to the radial direction of the second pressure plate 212, that is, the engaging hook 2241 moves towards the support base 100. Since the engaging hook 2241 is located within the engaging area 221 and opens downward, while the engaging groove 110 of the support base 100 opens upward, when the weight drives the support base 100 to rise, the engaging hook 2241 can be hooked on the side wall of the engaging groove 110, thereby completing the engagement action between the engaging hook 2241 and the support base 100.

[0050] In one embodiment, referring to Figure 3 As shown, the engaging module 200 further includes a driving element 310, and the pressure plate assembly 210 further includes a rotating shaft 213. The rotating shaft 213 is disposed above the second pressure plate 212, and the output end of the driving element 310 is connected to the rotating shaft 213.

[0051] In this embodiment, the engaging module 200 further includes a driving element 310, and the output end of the driving element 310 is connected to the rotating shaft 213. With this design, the driving element 310 can directly control the rotation of the rotating shaft 213, thereby driving the second pressure plate 212 to rotate relative to the first pressure plate 211 in the first direction or the second direction opposite to the first direction. By controlling the action of the rotating shaft 213 through the output end of the driving element 310, the size of the engaging area 221 can be accurately adjusted to ensure that the support base 100 can be accurately and stably engaged or disengaged at different operation stages. The control unit can be a programmable logic controller, and the driving element 310 can be a motor.

[0052] In one embodiment, the engaging module 200 further includes a sensor 320 and a control unit. The sensor 320 is used to obtain the position of the support base 100 relative to the engaging module 200. The control unit is electrically connected to the sensor 320 and the driving element 310. The control unit controls the rotation of the driving element 310 according to the position of the support base 100 relative to the engaging module 200 obtained by the sensor 320 to reduce or expand the engaging area 221. Among them, the sensor 320 can be a position photoelectric sensor or a Hall sensor, etc.

[0053] In this embodiment, the engaging module 200 further includes a sensor 320 and a control unit. The sensor 320 is used to obtain the position data of the support base 100 relative to the engaging module 200 in real time. The control unit is electrically connected to the sensor 320 and the driving element 310, and precisely controls the rotation direction and angle of the driving element 310 by analyzing the position data obtained by the sensor 320 to adjust the size of the engaging area 221.

[0054] Specifically, when feeding is required, the control unit first controls the driving element 310 to rotate in the first direction. The driving element 310 drives the second pressure plate 212 to rotate relative to the first pressure plate 211 in the first direction, controlling the expansion of the engaging area 221 and leaving a passage for the weight and the support base 100 to enter the engaging area. Then, the weight drives the support base 100 to descend into the engaging area 221. After the sensor detects that the weight drives the support base 100 to enter the engaging area 221 and the engaging slot 110 of the support base 100 descends below the engaging hook 2241, the control unit controls the driving element 310 to rotate in the second direction opposite to the first direction. By the rotation of the driving element 310, the second pressure plate 212 is driven to rotate relative to the first pressure plate 211 in the second direction opposite to the first direction, thereby controlling the reduction of the engaging area 221. The engaging hook 2241 in the engaging member 224 is located above the engaging slot 110 of the support base 100. That is to say, the engaging hook 2241 is located within the side wall of the engaging slot 110 of the support base 100. The weight drives the support base 100 to move upward. At this time, the engaging slot 110 of the support base 100 is engaged and limited with the engaging hook 2241 in the engaging member 224, and the engaging hook 2241 is suspended on the side wall of the engaging slot 110. Then, the weight drives the support base 100 to rise, the support base 100 drives the engaging module 200 to rise, and the engaging module 200 drives the feeding device to rise. In this way, the automatic feeding of the feeding device and the weight is realized. When the weight brings the feeding device into the single crystal furnace and the feeding is completed, the weight drives the feeding device to leave the single crystal furnace again. At this time, the weight descends and drives the feeding to be placed in the braking guide vehicle. At this time, the weight continues to descend until the bottom end of the feeding device is supported by the feeding trolley. At this time, the weight drives the support base 100 to continue to descend, so that the side wall of the engaging slot 110 of the support base 100 can move out of the downward opening of the engaging hook 2241. The control unit controls the driving element 310 to rotate in the first direction, thereby driving the second pressure plate 212 to rotate relative to the first pressure plate 211 in the first direction again. At this time, the engaging area 221 is controlled to expand, and the engaging hook 2241 moves radially outward to disengage from the support base 100. Then, the weight drives the support base 100 to rise, thereby realizing the dissociation of the support base 100 and the engaging area 221.

[0055] In one embodiment, the sensor 320 is a Hall sensor, and at least part of the support base 100 is made of a magnetic material.

[0056] In this embodiment, the sensor 320 is a Hall sensor, and at least a part of the support base 100 includes a magnetic material. The Hall sensor obtains the position data of the support base 100 relative to the engaging module 200 by detecting the magnetic field change generated by the magnetic part of the support base 100. Specifically, when the support base 100 approaches the engaging module 200, its magnetic part will affect the output signal of the Hall sensor. The control unit can accurately determine the position of the support base 100 by analyzing the signal change, and accordingly control the rotation of the driving element 310 to adjust the size of the engaging area 221.

[0057] In one embodiment, referring to Figure 3 as shown, the engaging module further includes a cover 330, and the cover 330 is used to protect the Hall sensor.

[0058] The cover 330 covers the outside of the Hall sensor, preventing dust, moisture or other substances in the external environment that may affect the performance of the sensor 320 from entering, so as to ensure that the Hall sensor can work stably and accurately even in a harsh environment. The material of the cover 330 can be polytetrafluoroethylene, which is a polymer material with excellent chemical resistance, high temperature resistance and low friction coefficient.

[0059] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0060] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
