Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading equipment, and in particular to a docking positioning device and a loading and unloading transportation system. Background Art

[0002] Traditional loading and unloading transportation systems typically utilize a conveyor system with an AGV (Automated Guided Vehicle). During the loading and unloading process, the conveyor system moves to the production line equipment and connects with it, and then the conveyor system is used for loading and unloading. For example, in the photovoltaic industry, a conveyor system must connect with the photovoltaic equipment to transport silicon wafer baskets to the photovoltaic equipment, or vice versa. However, existing conveyor systems are complex to operate during the docking process, seriously affecting operational efficiency. Summary of the Invention

[0003] Based on this, it is necessary to provide a docking positioning device and loading and unloading transportation system to improve the above defects, in order to address the problem that due to the walking and parking deviations of the conveying device in the current technology, position deviations are easy to occur when connecting with the production line equipment, and repeated returns and reconnections are required, which is complicated to operate and seriously affects work efficiency.

[0004] A docking positioning device is arranged on the side where the production line equipment and the conveying device are connected, and is used to position the conveying device. The docking positioning device includes:

[0005] The mounting frame has a stopper; and

[0006] The limiting assembly includes a movable seat and a rotating block; the movable seat is movably connected to the mounting frame along a first direction, and the rotating block is rotatably connected to the movable seat;

[0007] In which, the rotating block includes an initial position and a limit position when moving along the first direction with the movable seat. When the rotating block moves from the initial position to the limit position, it passes through the resisting portion and rotates to the limit state under the action of the resisting portion. When the rotating block rotates to the limit state, the rotating block limits the conveying device on the movable seat.

[0008] In one embodiment, the limiting assembly further includes a limiting block arranged on the movable seat, the limiting block is located on the side of the limiting position away from the initial position, and forms a limiting space for limiting the conveying device between the limiting block and the rotating block moved to the limiting position.

[0009] In one embodiment, the limiting assembly further includes an elastic stopper provided on the movable seat. The elastic stopper is located on a side of the limiting block facing the rotating block and can be retracted toward the movable seat under the action of an external force.

[0010] In one embodiment, when the rotating block rotates to the limiting state under the action of the resisting portion, the rotating block partially extends into the conveying device.

[0011] In one embodiment, the rotating block has a relatively fixed pushing portion and a limiting portion, and the pushing portion and the limiting portion are arranged around the rotation axis of the rotating block;

[0012] When the rotating block moves from the initial position to the limiting position, the pushing portion rotates to the top surface of the resisting portion under the resisting action of the resisting portion toward the conveying device, and drives the limiting portion to rotate until it extends into the conveying device.

[0013] In one embodiment, the docking and positioning device further comprises a driving assembly disposed on the mounting frame, and when the conveying device is positioned on the movable seat, the driving assembly can be in transmission connection with the conveying assembly of the conveying device.

[0014] In one embodiment, the driving assembly includes a power bracket and a driving member and a power output member provided on the power bracket, wherein the power bracket is movably connected to the mounting frame, and the driving member is in transmission connection with the power output member;

[0015] When the conveying device is limited on the moving seat, the power bracket can drive the power output member to be connected to or separated from the conveying component of the conveying device during the movement.

[0016] In one embodiment, the docking positioning device further includes an unlocking member disposed on the mounting frame, the unlocking member having an unlocking surface corresponding to the counterweight of the conveying device, and the unlocking surface is inclined relative to a vertical plane parallel to the first direction.

[0017] In one embodiment, the docking and positioning device further includes a slope block arranged on the mounting frame, the slope block having a slope surface inclined relative to the vertical direction, and when the conveying device approaches the docking and positioning device along the first direction, the climbing roller of the conveying device rolls along the slope surface in a manner of lifting the conveying device.

[0018] A loading and unloading transportation system includes a conveying device and a docking and positioning device as described in any of the above embodiments.

[0019] In the docking positioning device and loading and unloading transportation system described above, when the conveying device and the docking positioning device need to be docked, the body assembly of the conveying device moves toward the docking positioning device. Then, the moving seat moves from the initial position to the limit position, and the rotating block rotates to the limit state under the resistance of the resisting portion, so that the rotating block restricts the body assembly of the conveying device to the moving seat. When the conveying device and the docking positioning device need to be separated, the moving seat moves from the limit position to the initial position, and the rotating block rotates from the limit state under the action of the resisting portion to separate from the body assembly of the conveying device. At this time, the body assembly of the conveying device can move away from the docking positioning device.

[0020] In this way, the position limiting assembly of the docking positioning device limits the body assembly of the conveyor device, thereby achieving docking between the conveyor device and the docking positioning device, that is, achieving docking between the conveyor device and the production line equipment, simplifying the docking process and facilitating improved operational efficiency. Furthermore, using the docking positioning device to position the body assembly of the conveyor device facilitates improving the accuracy of the docking between the conveyor device and the production line equipment.

[0038] A loading and unloading transportation system provided in one embodiment of the present invention includes a conveying device and a docking positioning device. The docking positioning device is arranged on the side where the production line equipment can be docked with the conveying device, and is used to position the conveying device when the conveying device is docked with the production line equipment (that is, the conveying device is docked with the docking positioning device to finally realize the docking of the conveying device and the production line equipment), thereby ensuring accurate docking and improving work efficiency.

[0039] See Figure 1 、 Figure 2 and Figure 3 As shown, the conveying device includes a body component 10, a conveying component 11 and at least two blocking components 12. The body component 10 has two docking ends, which are respectively located on both sides of the body component 10 in the first direction, and can be docked with the docking positioning device to achieve docking with the production line equipment. The conveying component 11 is arranged on the body component 10 and has two opposite feed ends 111, which are respectively located at the two docking ends of the body component 10. The conveying component 11 can transport the material thereon in two directions between the two feed ends 111, thereby realizing the transmission of the material between the conveying component 11 and the production line equipment. At least two blocking components 12 are arranged at the two docking ends, each blocking component 12 is arranged corresponding to a feed end 111, and each blocking component 12 can open or close the corresponding feed end 111.

[0040] During actual operation, any docking end of the vehicle body component 10 can be directed toward the docking positioning device and moved toward the docking positioning device for docking, thereby achieving the docking of the docking end of the vehicle body component 10 with the production line equipment. At the same time, the blocking component 12 located at the feeding end 111 of the vehicle body component 10 close to the docking positioning device opens the feeding end, so that the conveying component 11 can convey materials to the production line equipment or convey materials on the production line equipment to the conveying component 11. In addition, the blocking component 12 located at the feeding end 111 of the vehicle body component 10 away from the docking positioning device closes the feeding end 111, thereby effectively preventing the material on the conveying component 11 from falling from the feeding end 111. It should be noted that, in Figure 1 In the illustrated embodiment, the first direction is the left-right direction.

[0041] In this way, since the above-mentioned conveying device has connecting ends at both ends in the first direction, and the two connecting ends are provided with blocking components 12 that can open or close the corresponding feeding ends 111, in actual production, any one of the two connecting ends can be flexibly selected to dock with the docking positioning device according to needs, without the need to significantly adjust the position and posture of the conveying device, thereby realizing the docking of the conveying device and the production line equipment, which greatly improves the flexibility of the conveying device docking and is conducive to improving production efficiency.

[0042] Please also see Figure 4 and Figure 5 As shown, in the embodiment of the present invention, each barrier assembly 12 has a pivot point 124 and is divided into a first end and a second end by the pivot point 124. The first end is capable of rotating about the pivot point 124, and the second end opens or closes the corresponding feed end 111 in response to the rotation of the first end. Thus, the first end of the barrier assembly 12 can be rotated about the pivot point 124 to cause the second end to open or close the corresponding feed end 111.

[0043] In some embodiments, each blocking assembly 12 includes a swing arm 121, a stopper 123, and a counterweight 122. The swing arm 121 is rotatably connected to the vehicle body assembly 10 about the pivot point 124. The counterweight 122 and the stopper 123 are connected to opposite ends of the swing arm 121, separated by the pivot point 124, and serve as the first end and the second end, respectively. The counterweight 122 can rotate about the pivot point 124 to the stopper 123 under the action of an external force, thereby opening the feed end 111. Furthermore, the counterweight 122 can return to the stopper 123 about the pivot point 124 under the action of its own weight, thereby closing the feed end 111.

[0044] Thus, during the docking process between the docking end and the docking positioning device, the corresponding counterweight 122 can rotate under the thrust force (i.e., the external force) provided by the docking positioning device, and drive the stopper 123 to rotate through the swing arm 121 to exit the corresponding feed end 111, so that materials can be output from or input to the feed end 111, i.e., the feed end 111 is opened. In other words, when a docking end of the vehicle body component 10 is docked with the docking positioning device, the feed end 111 located at the docking end of the vehicle body component 10 close to the docking positioning device is opened by the blocking component 12, and the feed end 111 located at the docking end of the vehicle body component 10 far from the docking positioning device is closed by the blocking component 12.

[0045] In this embodiment, the weight of the counterweight 122 is used to automatically close the feed end 111, and the contact between the counterweight 122 and the docking positioning device during the docking process is used to push the counterweight 122 to rotate, thereby automatically opening the feed end 111. There is no need to configure an electric or pneumatic drive structure, which simplifies the device structure.

[0046] Please also see Figure 6 、 Figure 7 and Figure 11 As shown, in this embodiment, the docking and positioning device includes a mounting frame 20 and an unlocking member 29 mounted on the mounting frame 20. The unlocking member 29 has an unlocking surface that is inclined relative to a vertical plane parallel to the first direction. In the process of the conveying device approaching the docking and positioning device along the first direction, the counterweight member 122 moves along the unlocking surface to drive the stopper 123 to rotate and exit the corresponding feed end 111. Preferably, the counterweight member 122 can be a counterweight roller, which can be rotatably mounted on the swing arm 121, so that the counterweight roller rolls along the unlocking surface during the docking end of the vehicle body assembly 10 and the docking and positioning device docking process, which is conducive to improving the reliability of unlocking.

[0047] Specifically in the embodiment, the docking and positioning device also includes a first sensing member 26 provided on the mounting frame 20. The first sensing member 26 is used to detect the position of the stopper 123 of the blocking assembly 12 of the conveying device toward the side of the docking and positioning device. When the first sensing member 26 detects that the stopper 123 of the blocking assembly 12 of the conveying device close to the side of the docking and positioning device is in a position to open the corresponding feed end 111, the production line equipment can be controlled to output the material to the conveying assembly 11 or to convey the material on the conveying assembly 11 to the production line equipment. When the first sensing member 26 detects that the stopper 123 of the blocking assembly 12 of the conveying device close to the side of the docking and positioning device is in a position to close the corresponding feed end 111, the production line equipment can be controlled to prohibit the output of the material to the conveying assembly 11 or to prohibit the conveying assembly 11 from conveying the material to the production line equipment. Optionally, the first sensing member 26 can be a proximity sensor.

[0048] Specifically in the embodiment, the docking positioning device also includes a second sensing member 25 provided on the mounting frame 20, and the second sensing member 25 is used to detect the position of the stopper 123 of the blocking assembly 12 of the conveying device away from the side of the docking positioning device. When the second sensing member 25 detects that the stopper 123 of the blocking assembly 12 of the conveying device away from the side of the docking positioning device is in a position that closes the corresponding feed end 111, the conveying assembly 11 can be controlled to convey the material toward the end away from the docking positioning device. When the second sensing member 25 detects that the stopper 123 of the blocking assembly 12 of the conveying device away from the side of the docking positioning device is in a position that opens the corresponding feed end 111, the conveying assembly 11 can be controlled to prohibit conveying the material toward the end away from the docking positioning device. Optionally, the second sensing member 25 can be a photoelectric sensor.

[0049] See Figure 2 、 Figure 6 and Figure 9 As shown, in the embodiment of the present invention, both connecting ends are provided with positioning members 13, and the positioning members 13 can be matched with the connecting positioning device during the connecting end and the connecting positioning device, thereby positioning the vehicle body component 10 to ensure accurate docking.

[0050] In this embodiment, the docking positioning device further includes a positioning block 22 disposed on the mounting frame 20, the positioning block 22 having a positioning slot 220. During docking between the docking end and the docking positioning device, the corresponding positioning member 13 can be inserted into the positioning slot 220, thereby achieving precise docking between the docking end of the vehicle body assembly 10 and the docking positioning device through the cooperation of the positioning member 13 and the positioning slot 220.

[0051] In an embodiment of the present invention, both connecting ends are provided with climbing rollers 14. During the docking process between the connecting end and the docking positioning device, the corresponding climbing rollers 14 roll along the docking positioning device in a manner of lifting the vehicle body assembly 10 to position the vehicle body assembly 10 in the vertical direction, so that after the connecting end and the docking positioning device are docked in place, the following transmission member 112 and the power output member 242 can cooperate with each other to realize the transmission of power on the docking positioning device to the conveying assembly 11.

[0052] In this embodiment, the docking positioning device also includes a slope block 23 arranged on the mounting frame 20, and the slope block 23 has a slope surface inclined relative to the vertical direction. When the vehicle body component 10 approaches the docking positioning device along the first direction, the corresponding climbing roller 14 rolls along the slope surface and rises to position the vehicle body component 10 in the vertical direction.

[0053] See Figure 3 、 Figure 6 and Figure 11As shown, in an embodiment of the present invention, the conveying device also includes a transmission member 112 that is transmission-connected to the two feeding ends 111 of the conveying assembly 11. During the docking process between the docking end and the docking positioning device, the corresponding transmission member 112 can be transmission-connected to the drive assembly 24 on the docking positioning device, so that the drive assembly 24 drives the conveying assembly 11 to convey materials through the transmission member 112. That is to say, when the docking end of the body assembly 10 is docked with the docking positioning device, the drive assembly 24 on the mounting frame 20 of the docking positioning device is transmission-connected to the corresponding transmission member 112, thereby transmitting the power of the drive assembly 24 to the conveying assembly 11 through the transmission member 112, and the conveying assembly 11 conveys the material under the drive of the power. In this way, the body assembly 10 is a non-powered frame, which does not require the connection of an electrical circuit or an air circuit, simplifies the structure of the body assembly 10, and facilitates the movement of the body assembly 10.

[0054] Specifically, in this embodiment, the drive assembly 24 includes a power bracket 241, a drive member 243 and a power output member 242 disposed on the power bracket 241. The power bracket 241 is movably connected to the mounting frame 20, and the drive member 243 is in transmission connection with the power output member 242. Optionally, the drive member 243 can be a motor.

[0055] When the docking end of the vehicle body assembly 10 is docked with the docking positioning device, the power bracket 241 can drive the power output member 242 to be connected or disconnected with the transmission member 112 during the movement. In this way, when the power output member 242 is connected with the transmission member 112, the power output of the driving member 243 is transmitted to the conveying assembly 11 through the power output member 242 and the transmission member 112. More specifically, the driving assembly 24 also includes a first slide rail, a first slider and a mobile driving member 245. The mounting frame 20 is provided with a first slide rail, and the power bracket 241 is provided with a first slider, and the first slider is slidably connected to the first slide rail, so that the power bracket 241 can be moved relative to the mounting frame 20. The mobile driving member 245 is provided on the mounting frame 20 and is connected to the power bracket 241 to drive the power bracket 241 to move along the first slide rail. Optionally, the first slide rail extends longitudinally in the vertical direction, that is, the power bracket 241 can be moved in the vertical direction relative to the mounting frame 20. Optionally, the moving driving member 245 may be a cylinder.

[0056] Specifically, in this embodiment, the conveying assembly 11 includes at least two parallel drive shafts 113 spaced apart along a first direction, with pulleys 114 mounted on each drive shaft 113. A conveyor belt 115 is mounted between the pulleys 114 on each pair of adjacent drive shafts 113. The rotation of the drive shafts 113 drives the conveyor belt 115 to move, thereby conveying the material on the conveyor belt 115 along the first direction. Transmission members 112 are mounted on the drive shafts 113 at the two feed ends 111, so that any docking end connected to the docking positioning device can be connected to the drive assembly 24 of the docking positioning device via the corresponding transmission member 112. Furthermore, pulleys 114 are mounted at both ends of each drive shaft 113, so that two conveyor belts 115 can be mounted between the pulleys 114 on each pair of adjacent drive shafts 113, thereby ensuring smoother transportation of the material on the conveyor belt 115.

[0057] More specifically, the transmission member 112 and the power output member 242 are gears that can mesh with each other. In this embodiment, the drive assembly 24 also includes a driving gear 244 installed on the output shaft of the drive member 243, and the driving gear 244 meshes with the power output member 242.

[0058] See Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment of the present invention, the bottom of the vehicle body assembly 10 has an accommodation space a for accommodating an AGV 200. The lifting platform 2001 of the AGV 200 can lift the vehicle body assembly 10 (lifting it off the ground), allowing the AGV 200 to transport the vehicle body assembly 10. Thus, the vehicle body assembly 10 and the AGV 200 utilize a separate structure, effectively solving the problem of requiring different AGVs for different application scenarios, improving the versatility of the vehicle body assembly 10 and the AGV 200, and increasing the utilization rate of the AGV 200. Alternatively, the AGV 200 can be a lurking AGV.

[0059] Specifically, in this embodiment, one of the lifting platform 2001 of the AGV 200 and the vehicle body assembly 10 has a positioning hole, and the other of the lifting platform 2001 and the vehicle body assembly 10 is provided with a positioning pin 2002. When the lifting platform 2001 lifts the vehicle body assembly 10, the positioning pin 2002 engages with the positioning hole, thereby achieving the positioning of the AGV 200 and the vehicle body assembly 10. Preferably, the positioning pin 2002 is provided on the lifting platform 2001 of the AGV 200, and the positioning hole is provided on the vehicle body assembly 10. It is understood that two or more mutually cooperating positioning pins 2002 and positioning holes may be provided between the lifting platform 2001 of the AGV 200 and the vehicle body assembly 10.

[0060] More specifically, the bottom of the vehicle body assembly 10 is provided with a support plate 101 that mates with the lifting platform 2001 of the AGV 200. Positioning holes are defined in the support plate 101. When the lifting platform 2001 of the AGV 200 is raised, the lifting platform 2001 contacts the support plate of the vehicle body assembly 10, and the positioning pins 2002 on the lifting platform 2001 of the AGV 200 engage with the positioning holes in the support plate.

[0061] Specifically in the embodiment, the bottom of the vehicle body assembly 10 is further provided with running wheels, so that the vehicle body assembly 10 can also be moved by the running wheels when there is no AGV 200 for transportation.

[0062] It should be noted that the vehicle body assembly 10 is not limited to being provided with only one conveying assembly 11. In some embodiments, the vehicle body assembly 10 includes multiple layers arranged in the vertical direction, and each layer of the vehicle body assembly 10 is provided with a conveying assembly 11. Of course, each layer of the vehicle body assembly 10 may also be provided with a plurality of conveying assemblies 11 arranged at intervals along a second direction perpendicular to the first direction, and each conveying assembly 11 extends longitudinally along the first direction. The first direction and the second direction are both perpendicular to the vertical direction. It is understandable that the number and position of the conveying assemblies 11 on the vehicle body assembly 10 can be set according to the specific circumstances, as long as they are compatible with the production line equipment connected thereto, and are not limited here.

[0063] Please also see Figures 6 to 9 As shown, in an embodiment of the present invention, the docking and positioning device further includes a limiting assembly 21 for limiting the position of the vehicle body assembly 10 of the conveying device. The limiting assembly 21 is disposed on the mounting frame 20. The limiting assembly 21 includes a movable base 210 and a rotating block 211. The movable base 210 is movably coupled to the mounting frame 20 along a first direction, and the rotating block 211 is rotatably connected to the movable base 210. The mounting frame 20 has a stop portion 216.

[0064] Among them, the rotating block 211 includes an initial position and a limit position in the process of moving along the first direction with the moving seat 210. When the rotating block 211 moves from the initial position to the limit position, it passes through the blocking portion 216 and rotates to the limit state under the action of the blocking portion 216. When the rotating block 211 rotates to the limit state, the rotating block 211 limits the body assembly 10 of the conveying device to the moving seat 210, thereby realizing the docking of the body assembly 10 of the conveying device with the docking positioning device, that is, realizing the docking of the conveying device with the production line equipment. Figure 8 In the illustrated embodiment, the first direction is the left-right direction.

[0065] When the conveying device and the docking positioning device need to be docked, the body assembly 10 of the conveying device moves toward the docking positioning device. Then, the movable seat 210 moves from the initial position to the limit position, and the rotating block 211 rotates to the limit state under the resistance of the resisting portion 216, so that the rotating block 211 limits the body assembly 10 of the conveying device to the movable seat 210. When the conveying device and the docking positioning device need to be separated, the movable seat 210 moves from the limit position to the initial position, and the rotating block 211 rotates from the limit state under the action of the body assembly 10 of the conveying device to a non-limiting state that does not block the body assembly 10 of the conveying device from moving away from the docking positioning device. At this time, the body assembly 10 of the conveying device can move away from the docking positioning device.

[0066] In this way, the body assembly 10 of the conveying device is limited by the limiting assembly 21 of the docking positioning device, thereby achieving the docking of the body assembly 10 of the conveying device with the docking positioning device, that is, achieving the docking of the conveying device and the production line equipment, simplifying the docking process, and helping to improve work efficiency. In addition, using the docking positioning device to position the body assembly 10 of the conveying device is conducive to improving the accuracy of the docking of the conveying device and the production line equipment. It should be noted that Figure 8 In the illustrated embodiment, the rotating block 211 is located at an initial position, and the limiting position is located to the left of the initial position.

[0067] Specifically, in this embodiment, the movable base 210 is movably coupled to the mounting frame 20 along a first direction via a second slide rail 2101 and a second slider 2102. Specifically, the second slide rail 2101 is connected to the mounting frame 20, and the second slider 2102 is connected to the movable base 210 and slidably coupled to the second slide rail 2101. Thus, the movable base 210 moves relative to the mounting frame 20 by sliding the second slider 2102 along the second slide rail 2101. It will be appreciated that the second slide rail 2101 extends longitudinally along the first direction.

[0068] Specifically in the embodiment, the limiting assembly 21 further includes a translation driver 214, which is disposed on the mounting frame 20 and is in transmission connection with the movable base 210 to drive the movable base 210 to move along the first direction. Optionally, the translation driver 214 can be a cylinder.

[0069] In some embodiments, the limiting assembly 21 further includes a limiting block 212 provided on the movable seat 210. The limiting block 212 is located on the side of the limiting position away from the initial position, and forms a limiting space for limiting the body assembly 10 of the conveying device between the limiting block 212 and the rotating block 211 that moves to the limiting position. In this way, when the rotating block 211 moves from the initial position to the limiting position, it rotates to the limiting state under the action of the supporting portion 216, so that part of the body assembly 10 of the conveying device is limited to the limiting space between the rotating block 211 and the limiting block 212. When the body assembly 10 of the conveying device needs to be separated from the docking positioning device, during the process of the movable seat 210 moving from the limiting position to the initial position, the limiting block 212 moves with the movable seat 210 toward the body assembly 10 of the conveying device and pushes the body assembly 10 away from the docking positioning device. At the same time, the rotating block 211 rotates from the limiting state to the non-limiting state that does not block the body assembly 10 from moving away from the docking positioning device, so that when the limiting block 212 pushes the body assembly 10 away from the docking positioning device, the rotating block 211 will not restrict the movement of the body assembly 10, thereby smoothly separating the body assembly 10 of the conveying device from the docking positioning device.

[0070] As the rotating block 211 rotates and pulls the vehicle body assembly 10, the vehicle body assembly 10 will be lifted to a certain extent in the vertical direction (i.e., the movement trajectory of the vehicle body assembly 10 is an upward convex arc), and it is easy to fall directly on the top of the limit block 212, affecting the vertical positioning of the vehicle body assembly 10 and making it impossible to limit part of the vehicle body assembly 10 between the rotating block 211 and the limit block 212. Therefore, in order to prevent the vehicle body assembly 10 from falling on the top of the limit block 212, the gap between the limit block 212 and the rotating block 211 is increased. However, due to the excessive gap between the limit block 212 and the rotating block 211, when part of the vehicle body assembly 10 is limited between the two, there is a large movable gap (i.e., the range of movement between the limit block 212 and the rotating block 211 is large), making it impossible to accurately position the vehicle body assembly 10.

[0071] To address the aforementioned issue of being unable to accurately position the vehicle body assembly 10, in one embodiment, the position-limiting assembly 21 further includes an elastic stopper 213 disposed on the movable seat 210. The elastic stopper 213 is located on the side of the position-limiting block 212 that faces the rotating block 211 and can be retracted toward the movable seat 210 under the action of an external force. Thus, when the position-limiting portion 2110 rotates and hooks onto the vehicle body assembly 10, a portion of the vehicle body assembly 10 first falls on top of the elastic stopper 213, causing the elastic stopper 213 to retract into the movable seat 210, thereby preventing the elastic stopper 213 from affecting the vertical positioning of the vehicle body assembly 10. As the vehicle body assembly 10 is positioned, a portion of the vehicle body assembly 10 falls back between the elastic stopper 213 and the rotating block 211. At this time, the elastic stopper 213 rebounds and extends out of the movable seat 210, thereby confining the portion of the vehicle body assembly 10 between the elastic stopper 213 and the rotating block 211. This reduces the movable space of the constrained vehicle body assembly 10 and improves the positioning accuracy of the vehicle body assembly 10. Optionally, the elastic stopper 213 and the limiting block 212 contact each other, which helps to increase the strength of the elastic stopper 213, and the limiting block 212 can guide the retraction and rebound extension of the elastic stopper 213.

[0072] See Figure 10 As shown, specifically in one embodiment, the limiting assembly 21 further includes a guide rod 215 and an elastic member 216, and the guide rod 215 is connected to the movable seat 210. The elastic block 213 includes a penetration end 2131 and a sliding end 2132 relative to the penetration end 2131. The penetration end 2131 can pass through the side of the movable seat 210 away from the limiting block 212 to the side of the movable seat 210 with the limiting block 212, and the sliding end 2132 is slidably connected to the guide rod 215. The elastic member 216 is provided on the side of the sliding end 2132 away from the movable seat 210, and the opposite ends of the elastic member 216 respectively abut against the sliding end 2132 and a nut threadedly connected to the guide rod 215 to provide a pre-tightening force that causes the sliding end 2132 to move toward the movable seat 210. Optionally, the guide rod 215 can be a guide screw.

[0073] In some embodiments, when the rotating block 211 rotates to a limited state under the action of the supporting portion 216, the rotating block 211 at least partially extends into the body assembly 10 of the conveying device, thereby limiting a portion of the body assembly 10 of the conveying device between the rotating block 211 and the limiting block 212.

[0074] Please continue to see Figure 8 As shown, in the embodiment of the present invention, the rotating block 211 has a relatively fixed limiting portion 2110 and a pushing portion 2111 , and the pushing portion 2111 and the limiting portion 2110 are arranged around the rotation axis of the rotating block 211 .

[0075] When the rotating block 211 moves from the initial position to the limit position, the pushing portion 2111 rotates to the top surface of the resisting portion 216 under the resisting action of the resisting portion 216 toward the side of the conveying device, and drives the limiting portion 2110 to rotate to extend into the body component 10 of the conveying device, thereby achieving the limitation of the body component 10 of the conveying device.

[0076] Furthermore, the side surface of the stopper 216 facing the vehicle body assembly 10 of the conveying device and the top surface of the stopper 216 are in an arc transition, so that the rotation of the rotating block 211 is smoother and more reliable.

[0077] In an embodiment of the present invention, the docking and positioning device further includes a third sensor 28 and a fourth sensor 27. The third sensor 28 is used to detect the position of the vehicle assembly 10 of the conveyor device. The fourth sensor 27 is used to detect the position of the AGV 200. Thus, the position information of the vehicle assembly 10 and the AGV 200 detected by the third and fourth sensors 28 and 27 can be used to accurately control the docking and positioning device's actions (e.g., the movement of the moving base and the power support), ensuring smoother and more reliable docking.

[0078] It should be noted that the material loading and unloading transportation system of the present invention can be applied to the photovoltaic industry, that is, the material is a silicon wafer basket and the production line equipment is a photovoltaic device. Of course, the material loading and unloading transportation system of the present invention can also be applied to other industries, which is not limited here.
