Description

Technical Field

[0001] This application relates to the technical field of automation equipment, and in particular to an automatic loading and unloading device that connects with an AGV (Automated Guided Vehicle). Background Technology

[0002] Automated Guided Vehicles (AGVs), also known as automated guided vehicles or automated guided transport vehicles, are industrial vehicles that automatically or manually load goods and travel along a set route to a designated location, where goods are then loaded and unloaded automatically or manually.

[0003] Currently, material handling in the workshop includes loading and unloading. Materials are typically placed on trays, and loading and unloading are equivalent to loading and unloading multiple trays. Traditional loading and unloading operations are either manually assisted or use suction cups. Manual loading and unloading involves manually placing the transport trays, requiring significant labor. Furthermore, multiple trays need to be stacked together before transport, making it easy to misalign them, necessitating readjustment and resulting in low efficiency. Using suction cups for loading and unloading presents challenges with insufficient suction for trays of different sizes, leading to difficulties in tray transfer and hindering integration with AGVs, resulting in low automation levels. Summary of the Invention

[0004] In order to improve the automation level of the connection between the loading and unloading device and the AGV trolley, this application provides an automatic loading and unloading device that connects with the AGV trolley.

[0005] This application provides an automatic loading and unloading device that connects with an AGV (Automated Guided Vehicle) trolley, employing the following technical solution: An automatic loading and unloading device that connects to an AGV (Automated Guided Vehicle) includes: The frame is provided with a docking space for AGV trolleys to enter, and the frame is provided with a loading station and a unloading station; A tray group, which is transported by the AGV, includes multiple trays arranged in parallel, and the outer wall of the trays is provided with snap-fit ​​grooves; The tray docking mechanism consists of two tray docking mechanisms disposed within the docking space. The two tray docking mechanisms correspond to the loading station and the unloading station, respectively. The tray docking mechanism is connected to the AGV trolley and is used to store the tray group and raise or lower the tray group to a set height. A tray transfer mechanism is provided on the frame and is used to transfer one of the trays in the tray group from the loading station to the unloading station. The material tray group is transported to the docking space by the AGV trolley. The material tray docking mechanism lifts the material tray group to the loading station. The material tray transfer mechanism sequentially transfers the material trays to the unloading station. After the workpieces in the material tray group are transferred by the robot arm, the material tray docking mechanism lowers the material tray group to a set height. The AGV trolley then transports the material tray group out of the docking space.

[0006] By adopting the above technical solution, the AGV transports the pallet assembly to the docking space within the frame. The pallet docking mechanism, located directly below the loading station, descends onto the AGV and transfers the pallet assembly from the AGV to the docking mechanism. The docking mechanism then lifts the pallet assembly to the loading station. The pallet transfer mechanism sequentially transfers each pallet from the loading station to the unloading station. After the robotic arm transfers the workpieces from the pallet assembly, the docking mechanism, located directly below the unloading station, lowers the pallet assembly to a set height, and the AGV enters the docking space. Within the space, after the tray docking mechanism places the tray assembly onto the AGV trolley, the tray docking mechanism is raised to a set height, and the AGV trolley transports the tray assembly to the docking space. Compared to traditional loading and unloading operations, which require manual assistance or use suction cups, making it difficult for the loading and unloading device to connect with the AGV trolley, this application uses two tray docking mechanisms and one tray transfer mechanism to automate the loading and unloading process without manual intervention, which helps to improve the automation level of the connection between the loading and unloading device and the AGV trolley.

[0007] Optionally, the tray docking mechanism includes a lifting assembly mounted on the frame and a clamping assembly mounted on the lifting assembly. The lifting assembly includes a lifting platform mounted in the docking space, a first clearance hole mounted on the lifting platform for the tray group to pass through, a first guide rail mounted vertically along the frame, a first guide groove mounted on the lifting platform near the first guide rail for the first guide rail to be embedded in, and a first driving member mounted on the frame. The first driving member drives the lifting platform to descend onto the AGV trolley so that the tray group passes through the first clearance hole. After the clamping assembly clamps the tray group, the first driving member drives the lifting platform to rise so that the tray group is located at the loading station.

[0008] By adopting the above technical solution, the material tray docking mechanism is lowered onto the AGV trolley by the lifting component, and then the material tray group is clamped and fixed by the clamping component. After the lifting component lifts the material tray group to the loading station, the AGV trolley drives away from the docking space. The lifting component drives the lifting platform to slide back and forth along the length of the first guide rail through the first driving component, so that the lifting component can lift or lower the material tray group to the set height.

[0009] Optionally, the clamping assembly includes two clamping seats symmetrically arranged on the lifting platform, a plurality of clamping members arranged on the clamping seats, a second guide rail arranged on the side of the lifting platform near the clamping seats and parallel to the width direction of the clamping seats, a second guide groove arranged on the clamping seats for the second guide rail to be embedded in, and a second driving member arranged on the lifting platform for driving the clamping seats to move horizontally. The second driving member drives the two clamping seats to move closer to each other so that the clamping members clamp the tray group.

[0010] By adopting the above technical solution, the second driving member drives the clamping seat to reciprocate along the length of the second guide rail. When it is necessary to clamp the material tray group, the second driving member drives the two clamping seats to move closer to each other, so that the clamping member clamps the two sides of the material tray group.

[0011] Optionally, the clamping member includes a support plate fixed on the clamping seat, a reinforcing rib disposed between the support plate and the clamping seat, and a snap-fit ​​block disposed on the side of the support plate away from the reinforcing rib and used for embedding into the snap-fit ​​groove.

[0012] By adopting the above technical solution, the clamping component includes a support plate, reinforcing ribs, and snap-fit ​​blocks. The reinforcing ribs help to enhance the strength and rigidity of the support plate. When the second driving component drives the two clamping seats to approach each other, the snap-fit ​​blocks are embedded in the snap-fit ​​groove, for example, in the snap-fit ​​groove on the end tray of the tray group. The clamping component lifts the end tray, thereby lifting the entire tray group.

[0013] Optionally, the material tray transfer mechanism includes a transfer component disposed on the frame and a fixing component disposed on the transfer component. The transfer component includes a transfer seat disposed on the frame, a second clearance hole disposed on the transfer seat for the material tray assembly to pass through, a third guide rail disposed on the frame and parallel to the length direction of the frame, a third guide groove disposed on the transfer seat for the third guide rail to be embedded in, and a third driving member disposed on the frame. After the fixing component fixes the material tray, the third driving member is used to drive the transfer seat to slide along the length direction of the third guide rail, so that the transfer seat is transferred from the loading station to the unloading station.

[0014] By adopting the above technical solution, the material tray transfer mechanism is located on the loading station through the transfer component. When the material tray docking mechanism brings the top material tray in the material tray group to the loading station, the fixing component on the transfer component fixes the top material tray. Then, the transfer component drives the transfer seat to move toward the unloading station through the third drive component. After the material tray docking mechanism on the unloading station side fixes the top material tray, the transfer component drives the transfer seat to move toward the loading station through the third drive component.

[0015] Optionally, the fixing component includes two fixing seats symmetrically arranged on the transfer seat, a fourth guide rail arranged on the transfer seat, a fourth guide groove arranged on the fixing seat for the fourth guide rail to be embedded, a fixing plate arranged on the fixing seat for embedding the snap-fit ​​groove, and a fourth driving member arranged on the transfer seat. The fourth driving member drives the two fixing seats to move closer to each other so that the fixing plate is embedded in the snap-fit ​​groove.

[0016] By adopting the above technical solution, the fixing component includes two fixing seats and fixing plates installed on the fixing seats. The two fixing plates are symmetrically arranged. The two fixing seats are driven to move closer to each other by the fourth driving component so that the fixing plates on the fixing seats are embedded in the snap-fit ​​groove to fix the material tray. After the material tray docking mechanism on the lower material station side fixes the top material tray, the two fixing seats are driven to move away from each other by the fourth driving component.

[0017] Optionally, the tray includes a receiving portion for placing workpieces, an enclosing portion disposed on the receiving portion and used to enclose the receiving portion, and an assembly ring groove disposed on the side of the receiving portion away from the enclosing portion. Two adjacent trays are a first tray and a second tray, and the enclosing portion of the second tray is embedded in the assembly ring groove of the first tray.

[0018] By adopting the above technical solution, since the material tray group is composed of multiple material trays stacked together, in order to enhance the stability of the material tray group during transportation, the material tray group is composed of a receiving part, an enclosing part and an assembly ring groove. Assuming that two adjacent material trays are the first material tray and the second material tray, and the first material tray is located above the second material tray, the enclosing part of the second material tray is embedded in the assembly ring groove of the first material tray.

[0019] Optionally, the first driving component is a motor lead screw drive structure.

[0020] By adopting the above technical solution, since the lifting platform needs to lift the material tray group, and the material tray group contains several material trays, a larger load-bearing capacity is required. Compared with the cylinder drive structure, the motor screw drive structure is better.

[0021] Optionally, the second driving component is two first cylinders, and the output shaft of the first cylinder is fixed to the clamping seat.

[0022] By adopting the above technical solution, each clamping seat is equipped with a first cylinder. The output shaft of the first cylinder is fixed to the clamping seat. The first cylinder controls the reciprocating sliding of the clamping seat. Compared with the motor screw drive structure, the cylinder drive structure is smaller in volume than the motor screw drive structure. It is more convenient to use the cylinder drive structure on the clamping seat.

[0023] Optionally, the third driving component is a second cylinder, the output shaft of which is fixed to the transfer seat; the fourth driving component is two third cylinders, the output shaft of which is fixed to the fixed seat.

[0024] By adopting the above technical solution, both the third and fourth driving components adopt a cylinder driving structure. The output shaft of the second cylinder is fixed to the transfer seat. The second cylinder is used to drive the transfer seat to slide back and forth along the length direction of the third guide rail. The output shaft of the third cylinder is fixed to the fixed seat. Each fixed seat is equipped with a corresponding third cylinder so that the two fixed seats are close to each other or far apart.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with the traditional loading and unloading operations, which are all manually assisted or use suction cups, making it difficult for the loading and unloading device to connect with the AGV, the solution of this application adopts two material tray docking mechanisms and one material tray transfer mechanism to realize the automation of loading and unloading without manual intervention, which is conducive to improving the automation level of the connection between the loading and unloading device and the AGV. 2. The material tray docking mechanism is lowered onto the AGV trolley via the lifting component, and then the material tray group is clamped and fixed by the clamping component. After the lifting component lifts the material tray group to the loading station, the AGV trolley drives away from the docking space. The lifting component drives the lifting platform to slide back and forth along the length of the first guide rail via the first drive component, so that the lifting component can lift or lower the material tray group to the set height.

[0026] 3. The material tray transfer mechanism is located at the loading station via the transfer component. When the material tray docking mechanism brings the top material tray in the material tray group to the loading station, the fixing component on the transfer component fixes the top material tray. Then, the transfer component drives the transfer seat to move toward the unloading station via the third drive component. After the material tray docking mechanism on the unloading station side fixes the top material tray, the transfer component drives the transfer seat to move toward the loading station via the third drive component.

[0035] This application discloses an automatic loading and unloading device that connects to an AGV (Automated Guided Vehicle). (Refer to...) Figure 1 and Figure 2 The system includes a frame 1, a tray assembly 6, a tray docking mechanism 8, and a tray transfer mechanism 9. The frame 1 has a connecting space 3 for the AGV trolley 2 to enter. A loading station 4 and a unloading station 5 are located above the frame 1, arranged sequentially along the length of the frame 1. The tray assembly 6, containing workpieces, is transported by the AGV trolley 2. The tray assembly 6 consists of several trays arranged side-by-side, each stacked on top of the AGV trolley 2. To facilitate the fixing of the tray assembly 6 by the tray docking mechanism 8 or the tray transfer mechanism 9, each tray has a locking groove 7 on its outer wall, with several locking grooves 7 arranged circumferentially around the tray. Two tray docking mechanisms 8 are installed within the connecting space 3, corresponding to the loading station 4 and the unloading station 5 respectively. One tray docking mechanism 8 is located directly below the loading station 4, and the other tray transfer mechanism 9 is located directly below the unloading station 5. The tray docking mechanism 8 connects to the AGV trolley 2 and is used to store the tray group 6 and raise or lower the tray group 6 to a set height. The tray transfer mechanism 9 is installed on the frame 1 and is used to transfer one tray of the tray group 6 from the loading station 4 to the unloading station 5.

[0036] Specifically, refer to Figure 3 and Figure 4The tray group 6 is transported to the connecting space 3 by the AGV trolley 2. The tray docking mechanism 8 corresponding to the loading station 4 lifts the tray group 6 onto the loading station 4. When the top tray of the tray group 6 is above the loading station 4, the tray transfer mechanism 9 transfers the top tray to the unloading station 5. During the process of the tray transfer mechanism 9 transferring the tray from the loading station 4 to the unloading station 5, a robot arm transfers the workpieces in the tray. After the tray is transported to the unloading station 5, the tray docking mechanism 8 lowers the tray to a set height, and then waits for the remaining trays to be stacked on top of the tray. After multiple trays are accumulated to form the tray group 6, the tray docking mechanism 8 lowers the tray group 6 to a set height. The AGV trolley 2 is equipped with a support frame 100. After the tray group 6 is placed on the support frame 100, the tray docking mechanism 8 rises, and the AGV trolley 2 transports the tray group 6 out of the connecting space 3. Compared to traditional loading and unloading operations, which rely on manual assistance or suction cups, making it difficult for the loading and unloading device to connect with the AGV trolley 2, this application uses two tray docking mechanisms 8 and one tray transfer mechanism 9 to automate the loading and unloading process without manual intervention, which helps to improve the automation level of the connection between the loading and unloading device and the AGV trolley 2.

[0037] It is worth noting that, such as Figure 5 As shown, since the tray group 6 is composed of multiple stacked trays, in order to prevent misalignment between two trays that could cause the tray group 6 to collapse, the tray in this embodiment includes a receiving portion 37, an enclosing portion 38, and an assembly ring groove 39. The receiving portion 37 is used to place the workpiece, the enclosing portion 38 is used to enclose the receiving portion 37, and a snap-fit ​​groove 7 is formed on the outer wall of the receiving portion 37; the assembly ring groove 39 is formed on the side of the receiving portion 37 away from the enclosing portion 38. To enhance the stability of the tray group 6 during transportation, it is assumed that two adjacent trays are a first tray 40 and a second tray 41, and the first tray 40 is located above the second tray 41, with the enclosing portion 38 of the second tray 41 embedded in the assembly ring groove 39 of the first tray 40.

[0038] Reference Figure 5 and Figure 7The tray docking mechanism 8 includes a lifting assembly 10 and a clamping assembly 11. The tray docking mechanism 8 is lowered onto the AGV trolley 2 via the lifting assembly 10, and then the tray group 6 is clamped and fixed by the clamping assembly 11. The lifting assembly 10 then lifts the tray group 6 to the loading station 4, after which the AGV trolley 2 leaves the docking space 3. The lifting assembly 10 includes a lifting platform 12, a first clearance hole 13, a first guide rail 14, a first guide groove 15, and a first driving component. The lifting platform 12 is installed within the docking space 3 and is slidably connected to the frame 1. The first clearance hole 13 is formed on the lifting platform 12, allowing the tray group 6 to pass through. The first guide rail 14 is fixed on the inner wall of the frame 1 and is arranged along the vertical direction of the frame 1. The first guide groove 15 is opened on the side of the lifting platform 12 near the first guide rail 14 and is used for the first guide rail 14 to be embedded. The first drive member is installed on the frame 1. The first drive member is any kind of motor screw drive structure in the prior art, so that the first drive member is used to drive the lifting platform 12 to reciprocate along the vertical direction.

[0039] Specifically, the AGV trolley 2 transports the tray group 6 containing the workpiece to the connecting space 3, and positions the tray group 6 directly below the loading station 4. The first drive unit drives the lifting platform 12 to descend onto the AGV trolley 2, so that the tray group 6 passes through the first clearance hole 13 and the support frame 100 passes through the first clearance hole 13. After the clamping assembly 11 clamps the tray at the end of the tray group 6, the first drive unit drives the lifting platform 12 to lift, thereby lifting the entire tray group 6. After the tray at the top of the tray group 6 is positioned at the loading station 4, the lifting platform 12 stops. After the tray transfer mechanism 9 transfers the tray at the top of the tray group 6, the second tray is then raised to the loading station 4.

[0040] Among them, reference Figure 7 and Figure 8The clamping assembly 11 includes two clamping seats 17, clamping members 18, a second guide rail 19, a second guide groove 20, and a second driving member. The two clamping seats 17 are symmetrically mounted on the lifting platform 12, and several clamping members 18 are fixed to the clamping seats 17. In this embodiment, the clamping members 18 include a support plate 22, a reinforcing rib 23, and a snap-fit ​​block 24. The support plate 22 is fixed to the clamping seat 17, the reinforcing rib 23 is fixed between the support plate 22 and the clamping seat 17, and the snap-fit ​​block 24 is fixed to the side of the support plate 22 away from the reinforcing rib 23 and is used to embed into the snap-fit ​​groove 7. Installing the reinforcing rib 23 helps to enhance the strength and rigidity of the support plate 22. The second guide rail 19 is fixed to the side of the lifting platform 12 near the clamping seat 17. The length direction of the second guide rail 19 is parallel to the width direction of the clamping seat 17, and the second guide groove 20 is formed on the clamping seat 17 for the second guide rail 19 to be embedded in. The second driving member is fixed on the lifting platform 12 and is used to drive the clamping seat 17 to move horizontally. The second driving member drives the two clamping seats 17 to move closer to each other so that the snap-fit ​​block 24 in the clamping member 18 is embedded in the snap-fit ​​groove 7. For example, it is embedded in the snap-fit ​​groove 7 on the end tray of the tray group 6. The clamping member 18 lifts the end tray, thereby lifting the entire tray group 6.

[0041] It is worth noting that the second drive assembly consists of two first cylinders. Each clamping seat 17 is equipped with a first cylinder, and the output shaft of the first cylinder is fixed to the clamping seat 17. The first cylinder controls the reciprocating sliding of the clamping seat 17. Compared with the motor screw drive structure, the cylinder drive structure is smaller in size, making it more convenient to use a cylinder drive structure on the clamping seat 17. The use of two first cylinders as the second drive assembly here is merely an example; of course, adjustments can be made according to specific circumstances, and no specific limitation is imposed.

[0042] Reference Figure 9 and 10 The tray transfer mechanism 9 includes a transfer component 25 and a fixing component 26. The transfer component 25 is mounted on the frame 1, and the fixing component 26 is mounted on the transfer component 25. The initial position of the transfer component 25 is located at the loading station 4. When the tray docking mechanism 8 brings the top tray of the tray group 6 to the loading station 4, the fixing component 26 on the transfer component 25 fixes the top tray. The transfer component 25 drives the transfer seat 27 to move towards the unloading station 5 via the third drive component. After all the workpieces on the tray have been transferred by the robot, the clamping component 11 in the tray docking mechanism 8 on the unloading station 5 fixes the tray. Then, the lifting component 10 of the tray docking mechanism 8 descends so that the tray leaves the unloading station 5. After that, the transfer component 25 moves towards the loading station 4 to prepare to transfer the next tray containing workpieces.

[0043] It is worth noting that the third driving component is the second cylinder. Both the third and fourth driving components adopt a cylinder-driven structure. The output shaft of the second cylinder is fixed to the transfer seat 27. The second cylinder is used to drive the transfer seat 27 to slide back and forth along the length of the third guide rail 29. The use of the second cylinder as the third driving component here is only for illustrative purposes. Of course, adjustments can be made according to specific circumstances, and no specific limitation is made.

[0044] Among them, reference Figure 10 and Figure 11 The transfer assembly 25 includes a transfer seat 27, a second clearance hole 28, a third guide rail 29, a third guide groove 30, and a third drive component. The transfer seat 27 is mounted on the frame 1. The second clearance hole 28 is formed on the transfer seat and the feeding tray assembly 6 protrudes through it. The third guide rail 29 is mounted on the frame 1 and parallel to its length. The third guide groove 30 is formed on the transfer seat 27 and allows the third guide rail 29 to be inserted, enabling the transfer seat 27 to slide along the length of the third guide rail 29, further regulating the displacement trajectory of the transfer seat 27 and improving the accuracy of the transfer mechanism's movement. The third drive component is mounted on the frame 1 and drives the transfer seat 27 to slide along the length of the third guide rail 29, causing the transfer seat 27 to reciprocate between the loading station 4 and the unloading station 5. The third driving component drives the transfer seat 27 to reach one side of the loading station 4. After the fixing component 26 fixes the tray, the third driving component drives the transfer seat 27 to move toward the unloading station 5. After the tray docking mechanism 8 on the side of the unloading station 5 fixes the top tray, the transfer component 25 drives the transfer seat 27 to move toward the loading station 4 through the third driving component.

[0045] It is worth noting that the fourth driving component includes two third cylinders. Each transfer seat 27 is equipped with a third cylinder, and the output shaft of the third cylinder is fixed to the fixed seat 32. Each fixed seat 32 is equipped with a corresponding third cylinder to bring the two fixed seats 32 closer to or further apart from each other. The inclusion of two third cylinders in the fourth driving component is merely an example; adjustments can be made according to specific circumstances, and no specific limitation is imposed.

[0046] The fixing component 26 includes two fixing seats 32, a third guide rail 29, a fourth guide groove 34, and a fixing plate 35. The two fixing seats 32 are symmetrically mounted on the transfer seat 27. The fourth guide rail 39 is fixed on the transfer seat 27. The fourth guide groove 34 is formed on the fixing seat 32 and allows the fourth guide rail 39 to be embedded. The fixing plate 35 is fixed on the fixing seat 32 and is used to embed into the snap-fit ​​groove 7. When the fixing plate 35 is embedded into the snap-fit ​​groove 7, the tray is fixed. The two fixing seats 32 are driven to move closer to each other by the fourth driving component, so that the fixing plate 35 on the fixing seat 32 is embedded into the snap-fit ​​groove 7 to fix the tray. After the tray docking mechanism 8 on the side of the feeding station 5 fixes the top tray, the two fixing seats 32 are driven to move away from each other by the fourth driving component.

[0047] The implementation principle of an automatic loading and unloading device that connects with an AGV (Automated Guided Vehicle) in this embodiment is as follows: The AGV trolley 2 transports the tray group 6 to the connection space 3 within the frame 1. The tray docking mechanism 8, located directly below the loading station 4, descends onto the AGV trolley 2 and transfers the tray group 6 from the AGV trolley 2 to the tray docking mechanism 8. The tray docking mechanism 8 then lifts the tray group 6 to the loading station 4. Notably, each tray in the tray group 6 is sequentially located on the loading station 4. The tray transfer mechanism 9 then sequentially transfers each tray from the loading station 4 to the unloading station 5. After the robotic arm transfers the workpieces from the tray group 6, the tray docking mechanism 8, located directly below the unloading station 5, lowers the tray group 6 to a set height. The AGV trolley 2 enters the connecting space 3. After the tray docking mechanism 8 places the tray assembly 6 onto the AGV trolley 2, the tray docking mechanism 8 is raised to a set height, and the AGV trolley 2 transports the tray assembly 6 to the connecting space 3. This application scheme uses two tray docking mechanisms 8 and one tray transfer mechanism 9 to automate the loading and unloading process without manual intervention, which helps to improve the automation level of the connection between the loading and unloading device and the AGV trolley 2.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
