[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0043] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0044] See also Figure 1 , the embodiment of the present application discloses a loading and unloading device 1 for hooking a receiving component 2. Please also refer to Figure 2 and Figure 3 The loading and unloading device 1 includes a bracket 11, a hook assembly 12 and a sensor switch 13. The bracket 11 can be moved in a first direction (such as Figure 1The hooking component 12 comprises a base 121 and a hook 122, wherein the base 121 is disposed on the side of the bracket 11 facing the accommodating component 2. The hook 122 is used to hook the accommodating component 2, and the hook 122 is slidably disposed on the base 121, and can move relative to the base 121 in the opposite direction of the first direction when interfering with the accommodating component 2. The induction switch 13 is used to generate an early warning signal when the hook 122 moves relative to the base 121 in the opposite direction of the first direction.

[0045] The receiving component 2 can be used to place a crystalline silicon wafer, and of course, other materials can also be placed therein, which is not limited here.

[0046] In addition, the first direction may be a vertical direction or a horizontal direction, and of course may be other directions at any angle in space, which is not limited here.

[0047] The working principle of the loading and unloading device 1 provided in this embodiment under normal conditions is that the bracket 11 moves along the first direction to approach the accommodating component 2, and after the hook 122 hooks the accommodating component 2, the bracket 11 moves in the opposite direction of the first direction, and the accommodating component 2 moves synchronously with the hook 122. It should be noted that when the bracket 11 approaches the accommodating component 2, the bracket 11 and the base 121 are staggered from the accommodating component 2, and only the hook 122 will contact the accommodating component 2.

[0048] However, when the position of the accommodating component 2 is offset, the hook 122 may interfere with the accommodating component 2 when the bracket 11 approaches the accommodating component 2 along the first direction. If the bracket 11 has a tendency to continue to move at this time, the hook 122 will continue to apply force to the accommodating component 2, causing the accommodating component 2 to deform, or even damage the hook 122 and the accommodating component 2. In order to improve this problem, in this embodiment, the hook 122 can move relative to the base 121 along the first direction. If the hook 122 interferes with the accommodating component 2, the bracket 11 and the base 121 are offset from the accommodating component 2 and can continue to move. During the process of the bracket 11 and the base 121 continuing to move, the force applied by the accommodating component 2 to the hook 122 will push the hook 122 to move relative to the base 121 in the opposite direction of the first direction, thereby achieving the purpose of buffering.

[0049] It is understandable that the distance that the hook 122 moves in the opposite direction of the first direction relative to the base 121 is limited. When the distance that the hook 122 moves reaches the maximum, the hook 122 and the base 121 will be relatively fixed again. At this time, if the frame and the base 121 continue to move, the accommodating component 2 will still be deformed or even the hook 122 and the accommodating component 2 will be damaged. Therefore, the induction switch 13 is also provided in this embodiment. When the induction switch 13 detects that the hook 122 moves in the opposite direction of the first direction relative to the base 121, it will generate an early warning signal, and the machine can be stopped according to the early warning signal, that is, the bracket 11 can be restricted from continuing to move in the first direction according to the early warning signal.

[0050] In this embodiment, after the bracket 11 is restricted to continue to move in the first direction, the bracket 11 can be moved in the opposite direction of the first direction to reset, so that the position of the accommodating component 2 can be adjusted after the hook 122 is separated from the accommodating component 2. In other embodiments, after the bracket 11 is restricted to continue to move in the first direction, the accommodating component 2 can also be moved in the first direction, so that the accommodating component 2 is away from the bracket 11 and the accommodating component 2 is separated from the hook 122, and the position of the accommodating component 2 can be adjusted. Of course, after the bracket 11 is restricted to continue to move in the first direction, there can also be other ways to adjust the relative position of the bracket 11 and the accommodating component 2, which are not limited here.

[0051] In summary, in this embodiment, the hook 122 is slidably set on the base 121, so that after the hook 122 interferes with the accommodating component 2, the hook 122 can move in the opposite direction of the first direction relative to the base 121 due to the stop of the accommodating component 2, thereby achieving the purpose of buffering. At the same time, the sensing switch 13 generates an early warning signal to achieve the purpose of early warning. According to the early warning signal, the bracket 11 can be restricted from continuing to move, thereby avoiding the deformation of the accommodating component 2 or even damage to the hook 122 and the accommodating component 2.

[0052] See also Figure 3 In some embodiments, the base 121 has a mounting surface 1211, the mounting surface 1211 is oriented away from the accommodating component 2, the hook 122 protrudes from the mounting surface 1211 when it moves in the opposite direction of the first direction relative to the base 121, and the sensing switch 13 is disposed on the mounting surface 1211 and is used to generate a warning signal when the hook 122 protrudes from the mounting surface 1211.

[0053] In this embodiment, when the hook 122 interferes with the accommodating component 2 and causes the hook 122 to move in the opposite direction of the first direction relative to the base 121, the end of the hook 122 away from the accommodating component 2 can protrude from the mounting surface 1211, and the sensing switch 13 generates a warning signal when detecting that the end of the hook 122 away from the accommodating component 2 protrudes from the mounting surface 1211.

[0054] It is understandable that, in the process of the bracket 11 moving along the first direction, the hook 122 may automatically move in the opposite direction of the first direction due to bumps or jams, thereby protruding a small distance from the mounting surface 1211. At the same time, since the sensing switch 13 has a certain thickness in the first direction, the sensing switch 13 in this embodiment can be configured to detect the hook 122 only after the hook 122 protrudes a preset distance from the mounting surface 1211, thereby generating a warning signal. When the distance that the hook 122 protrudes from the mounting surface 1211 is less than the preset distance, the sensing switch 13 cannot detect the hook 122, thereby preventing the hook 122 from accidentally protruding from the mounting surface 1211 and causing a shutdown.

[0055] In some other embodiments, the sensing switch 13 may also be a pressure switch, and is disposed on a surface of the hook 122 facing the mounting surface 1211 .

[0056] In some more specific embodiments, the loading and unloading device 1 further includes a driving member (not shown in the figure) and a control unit (not shown in the figure). The driving member is connected to the bracket 11 and is used to drive the bracket 11 to move. The driving member and the induction switch 13 are both electrically connected to the control unit. When the control unit receives the warning signal, the control unit controls the driving member to stop working to limit the bracket 11 from continuing to move.

[0057] The driving member may be a motor, or other driving devices, which is not limited here.

[0058] The induction switch 13 is electrically connected to the control unit so that the control unit can receive the warning signal generated by the induction switch 13; the driving member is electrically connected to the control unit so that the control unit can control whether the driving member works or not. Specifically, during the normal operation of the loading and unloading device 1, the control unit controls the driving member to work, that is, controls the driving member to drive the bracket 11 to move along the first direction and approach the accommodating component 2. When the hook 122 interferes with the accommodating component 2, the induction switch 13 generates a warning signal and transmits it to the control unit. After receiving the warning signal, the control unit controls the driving member to stop, that is, controls the driving member to stop working, so that the bracket 11 stops moving further.

[0059] The control unit receives the warning signal and controls the driving component to stop, thereby limiting the further movement of the bracket 11, thereby improving the automation and intelligence of the loading and unloading device 1, and can achieve shutdown in a shorter time, avoiding the situation where the hook 122 moves to the farthest distance in the opposite direction of the first direction relative to the base 121 before stopping.

[0060] In some other more specific embodiments, the driving member may also be controlled manually.

[0061] In some embodiments, the induction switch 13 is an infrared detection switch.

[0062] In this embodiment, the infrared detection switch can be a reflective type. Specifically, the infrared detection switch emits an infrared beam. When the hook 122 does not move, the infrared beam is transmitted along the emission direction, and the infrared detection switch does not receive the infrared beam, so no warning signal is generated; when the hook 122 moves relative to the base 121 in the opposite direction of the first direction to the transmission path of the infrared beam, the infrared beam is transmitted to the surface of the hook 122 and then reflected. The infrared detection switch generates a warning signal after receiving the reflected infrared beam.

[0063] Providing an infrared detection switch can quickly and accurately detect whether the hook 122 moves in the opposite direction of the first direction relative to the base 121.

[0064] In some other embodiments, the induction switch 13 may also be a Hall switch, etc., which is not limited here.

[0065] See also Figure 4 In some embodiments, the loading and unloading device 1 further includes an elastic member 14 , and the elastic member 14 is used to apply an elastic force along a first direction to the hook 122 .

[0066] It is understandable that, during the movement of the bracket 11 along the first direction, the hook 122 may automatically move in the opposite direction of the first direction due to bumps or jams, thereby erroneously triggering the sensor switch 13 to generate a warning signal. In order to solve this problem, the present embodiment is provided with an elastic member 14, which is used to apply an elastic force along the first direction to the hook 122, so that the hook 122 will not move in the opposite direction of the first direction relative to the base 121 when it does not interfere with the accommodating component 2, thereby avoiding erroneous triggering of the sensor switch 13.

[0067] In addition, when the hook 122 interferes with the accommodating component 2 and the sensing switch 13 generates a warning signal, the bracket 11 stops moving along the first direction and can be reset in the opposite direction of the first direction to adjust the position of the accommodating component 2. During the resetting process of the bracket 11, the elastic force applied by the elastic member 14 to the hook 122 can reset the hook 122, thereby stopping the sensing switch 13 from generating a warning signal.

[0068] In some other embodiments, the hook 122 may also be manually reset during the process of resetting the bracket 11 .

[0069] Please continue reading Figure 4In some more specific embodiments, the base 121 is provided with a guide hole 1212, and the axis of the guide hole 1212 is parallel to the first direction. The hook 122 includes a guide portion 1221 and a hooking portion 1222, the guide portion 1221 is slidably matched with the guide hole 1212, and the hooking portion 1222 is connected to the guide portion 1221, and the hooking portion 1222 is used to hook the accommodating component 2.

[0070] The guide portion 1221 of the hook 122 is slidably matched with the guide hole 1212, that is, the guide portion 1221 of the hook 122 is slidably disposed in the guide hole 1212, and can move relative to the base 121 along the axis of the guide hole 1212. Since the axis of the guide hole 1212 is parallel to the first direction, the hook 122 can move relative to the base 121 in the opposite direction of the first direction.

[0071] The spatial freedom of the guide portion 1221 of the hook 122 can be limited by the guide hole 1212, so that the guide portion 1221 only has the freedom in the first direction, thereby limiting the guide portion 1221 to move only in the first direction.

[0072] In some other more specific embodiments, the base 121 may also be provided with a guide rail, the guide rail extends along the first direction, and the guide portion 1221 is provided on the guide rail.

[0073] Please also read Figure 5 and Figure 6 In some embodiments, the hook portion 1222 is moved along the second direction (eg Figure 5 The second direction is perpendicular to the first direction. The base 121 can move to a first position along the first direction and can move to a third direction (as shown in FIG. Figure 6 Z) moves from the first position to the second position so that the hooking portion 1222 hooks the accommodating component 2, and the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0074] In this embodiment, the accommodating component 2 may be provided with a groove 21 for cooperating with the hooking portion 1222, so that the hooking portion 1222 can hook the accommodating component 2. The groove 21 has an opening facing the opposite direction of the second direction.

[0075] When the bracket 11 is at a position away from the accommodating component 2, the hooking portion 1222 and the groove 21 are staggered from the groove 21 in both the first direction and the second direction. When the bracket 11 moves to the first position along the first direction, the hooking portion 1222 is staggered from the groove 21 in the first direction, and forms a gap with the groove 21 in the third direction, that is, when the bracket 11 is in the first position, the hooking portion 1222 is located at one side of the opening of the groove 21 in the third direction; the bracket 11 then moves from the first position to the second position along the third direction, so that the hooking portion 1222 moves along the second direction and enters the groove 21 through the opening of the groove 21 to hook the accommodating component 2, that is, when the bracket 11 is in the second position, the hooking portion 1222 is located in the groove 21.

[0076] In this embodiment, the bracket 11 first moves along the first direction and then moves along the third direction to hook the accommodating component 2, so that the hook 122 can only extend along the second direction, reducing the complexity of the structure of the hook 122.

[0077] In some other embodiments, the hooking portion 1222 may also move along the first direction to the first position, and then move along the second direction from the first position to the second position.

[0078] See also Figure 6 In some more specific implementations, the base 121 is provided with at least two hooks 122, and the at least two hooks 122 are arranged along the third direction.

[0079] At least two hooks 122 arranged along the third direction can hook the accommodating component 2 at the same time, so that the loading and unloading device 1 can balance the force acting on the accommodating component 2 when hooking the accommodating component 2, thereby avoiding the accommodating component 2 from deviating in the third direction and causing the material of the accommodating component 2 to shift.

[0080] In some other more specific implementations, the base 121 may be provided with a hook 122 , and the center of gravity of the accommodating component 2 is in the first direction of the hook 122 .

[0081] Please also read Figure 6 and Figure 7 In some embodiments, the base 121 is provided with a mounting groove 1213, the mounting groove 1213 has a top surface 1213a, the top surface 1213a faces the accommodating component 2, the guide hole 1212 passes through the top surface 1213a and the mounting surface 1211, the elastic member 14 is sleeved on the guide portion 1221, and one end of the elastic member 14 abuts against the top surface 1213a, and the other end abuts against the hooking portion 1222.

[0082] In this embodiment, the top surface 1213a faces the accommodating component 2, that is, the top surface 1213a and the mounting surface 1211 are arranged opposite to each other. The mounting surface 1211 is the aforementioned mounting surface 1211 for setting the induction switch 13. The guide hole 1212 passes through the top surface 1213a and the mounting surface 1211, one end of the guide portion 1221 is arranged in the guide hole 1212, and the other end extends into the mounting groove 1213, and the hook portion 1222 is connected to the end of the guide portion 1221 extending into the mounting groove 1213.

[0083] The elastic member 14 is sleeved on the guide portion 1221, and one end of the elastic member 14 abuts against the top surface 1213a, and the other end abuts against the hooking portion 1222. The elastic member 14 applies an elastic force along the first direction to the hooking portion 1222. When the hooking portion 1222 does not interfere with the accommodating component 2, the elastic force applied by the elastic member 14 to the hooking portion 1222 enables the hooking portion 1222 to be stably located in the mounting groove 1213 at one end away from the top surface 1213a, and at the same time, the guide portion 1221 does not protrude from the mounting surface 1211. When the hooking portion 1222 interferes with the accommodating component 2, the accommodating component 2 applies a force in the opposite direction of the first direction to the hooking portion 1222 to overcome the elastic force and push the hooking portion 1222 to move in the opposite direction of the first direction, so that the guide portion 1221 moves in the opposite direction of the first direction and protrudes from the mounting surface 1211.

[0084] In some other embodiments, one end of the elastic member 14 may be connected to the bottom surface opposite to the mounting groove 1213 , and the other end may be connected to the hooking portion 1222 .

[0085] Please refer again Figure 5 In some more specific embodiments, the hooking component 12 includes a first base 1214, a second base 1215 and a third base 1216 arranged in sequence along the second direction, the hook 122 arranged on the first base 1214 includes a first hooking portion 1223, the hook 122 arranged on the second base 1215 includes a second hooking portion 1224 and a third hooking portion 1225, the hook 122 arranged on the third base 1216 includes a fourth hooking portion 1226, the first hooking portion 1223 and the second hooking portion 1224 are arranged opposite to each other, and the third hooking portion 1225 and the fourth hooking portion 1226 are arranged opposite to each other.

[0086] In this embodiment, the bracket 11 can extend along the second direction, the first base 1214 and the third base 1216 can be located at two ends of the bracket 11 in the second direction, and the second base 1215 is located between the first base 1214 and the third base 1216. The mounting groove 1213 provided on the second base 1215 can penetrate the second base 1215 along the second direction, and the second hooking portion 1224 and the third hooking portion 1225 of the hook 122 of the second base 1215 are respectively provided on both sides of the guide portion 1221 in the second direction, so that the second hooking portion 1224 can be arranged opposite to the first hooking portion 1223 of the hook 122 of the first base 1214, and the third hooking portion 1225 can be arranged opposite to the third hooking portion 1225 of the hook 122 of the second base 1215.

[0087] When the bracket 11 is close to the accommodating component 2, the first hooking portion 1223 and the second hooking portion 1224 can cooperate to hook one accommodating component 2, and the third hooking portion 1225 and the fourth hooking portion 1226 can cooperate to hook one accommodating component 2, so that the loading and unloading device 1 can hook two accommodating components 2 at a time, thereby improving the efficiency of the loading and unloading device 1 in hooking the accommodating component 2. In addition, the second hooking portion 1224 and the third hooking portion 1225 are arranged on the same second base 1215, which can reduce the mass of the loading and unloading device 1, thereby reducing the energy consumption of driving the loading and unloading device 1 to move.

[0088] Of course, there may be multiple second bases 1215 , and the multiple second bases 1215 are arranged at intervals along the second direction, so that the loading and unloading device 1 can hook more accommodating components 2 at one time, further improving the efficiency of the loading and unloading device 1 in hooking the accommodating components 2.

[0089] In some other more specific implementations, the hooking component 12 may also only be provided with a plurality of first bases 1214 and second bases 1215 of the same number, and each first base 1214 cooperates with a second base 1215 to hook a receiving component 2 .

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
