Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment, and in particular to an intelligent conveying and sorting system. Background Technology

[0002] With the improvement of social productivity and the increasing variety of commodities, the sorting of goods in the production and circulation fields has become a time-consuming, labor-intensive, space-consuming, error-prone, and complex department. Therefore, the sorting and conveying system has become an important branch of the workpiece handling system.

[0003] However, current related operations still rely heavily on manual labor. After the workpiece is produced, it needs to be manually transferred to the resting area. Subsequently, it also needs to be manually moved to the welding, pad printing and other processing stations. This manual transportation method is not only inefficient, but also increases labor and management costs, making it difficult to adapt to the needs of large-scale and automated production. Summary of the Invention

[0004] The purpose of this application is to provide an intelligent conveying and sorting system to solve the problem that current related operations still rely heavily on manual labor. After the workpieces are produced, they need to be manually transferred to the resting area, and then manually moved to the welding, pad printing and other processing stations. This manual conveying method is not only inefficient, but also increases labor and management costs, and is difficult to adapt to the needs of large-scale and automated production.

[0005] The intelligent conveying and sorting system provided in this application adopts the following technical solution: An intelligent conveying and sorting system includes a first track, a second track, a feeding device, a discharging device, multiple track trolleys, and multiple storage racks. Multiple connecting rods arranged in a rectangular array are fixedly connected to the upper ends of the first track and the second track. The feeding device and the discharging device are fixedly arranged between the first track and the second track. Rotating shafts are provided inside both ends of the multiple track trolleys. L-shaped buckles are rotatably connected to the outer walls of the multiple rotating shafts. A counterweight is fixedly connected to one side of the upper end of the multiple L-shaped buckles. A top cover is fixedly connected to the upper end of the multiple storage racks. Two slots arranged in a mirror distribution are opened on both sides of the top cover.

[0006] By adopting the above technical solution, the first and second tracks are used as conveyor tracks and can be securely fixed to the upper part of the factory building via connecting rods. This facilitates the transport of workpieces to designated locations, forming a complete conveyor track and ensuring the structural stability of the entire conveyor system during operation. The loading and unloading devices are located between the first and second tracks, enabling continuous operation of workpiece loading, conveying, and unloading, reducing manual handling, and simplifying the workflow. The rotating shafts at both ends of the track trolley provide rotational support for the L-shaped buckles, allowing them to rotate flexibly around the shafts. With the help of the counterweight, the L-shaped buckle can be smoothly inserted into the slots on both sides of the top cover of the storage rack, realizing the quick docking of the track trolley and the storage rack. At the same time, the L-shaped buckle can slide smoothly in the slot. When the track trolley moves into the unloading device, the unloading device can lift the L-shaped buckle, so that the L-shaped buckle can be pulled out from the slot, thereby releasing the storage rack. The loading and unloading devices facilitate the quick docking and release of the storage rack. Multiple storage racks can be used with multiple track trolleys to realize the batch transportation of workpieces, effectively improving the transportation efficiency and adapting to the needs of large-scale and automated operations.

[0007] Preferably, each of the multiple track trolleys has two rotating columns fixedly connected to its upper end in a mirror-shaped arrangement. Each of the multiple rotating columns has a pulley frame rotatably connected to its upper outer wall. Each of the multiple pulley frames has two sliding wheels rotatably connected to its inner sides. Each of the multiple track trolleys has a first rotating seat fixedly connected to its upper end. Each of the multiple first rotating seats has a first motor and a first controller fixedly connected to one side. Each of the multiple first rotating seats has a drive wheel rotatably connected inside its inner side. The output end of each of the multiple first motors passes through the first rotating seat and is fixedly connected to the drive wheel.

[0008] By adopting the above technical solution, the rotating column at the upper end of the track trolley provides fixed support for the pulley frame, which can rotate flexibly around the rotating column, thus allowing for flexible direction changes when encountering corners. The contact and cooperation between the sliding wheels and the inner wall of the track reduces friction during the movement of the track trolley, making the movement of the track trolley along the first and second tracks smoother and more stable, avoiding jamming. The first rotating seat provides a stable mounting base for the drive wheel and the first motor. The first controller can receive wireless signals from an external PLC controller, thereby controlling the start of the first motor. The output end of the first motor drives the drive wheel to rotate, and the drive wheel contacts the bottom of the track to generate driving force, driving the track trolley to move along the first and second tracks. No manual traction is required, realizing automated conveying of workpieces and improving conveying efficiency.

[0009] Preferably, a first infrared receiver is fixedly connected to one side of the upper end of the first track, and a second infrared receiver is fixedly connected to the end of the upper end of the first track away from the first infrared receiver.

[0010] By adopting the above technical solution, the first infrared receiver and the second infrared receiver on the first track form an inductive cooperation with the infrared transmitters of the feeding device and the unloading device, respectively, which can accurately receive infrared signals from the feeding and unloading ends, realize precise positioning between the first track, the second track and the feeding device and the unloading device, and avoid alignment deviation.

[0011] Preferably, the feeding device includes a first support frame, with two first telescopic rods arranged in a mirror image fixedly connected to the upper end of the first support frame, a first electric push rod fixedly connected to the upper end of the first support frame, a first lifting rail fixedly connected to the telescopic ends of the two first telescopic rods, a first infrared transmitter fixedly connected to one side of the upper end of the first lifting rail, the first infrared transmitter corresponding to a second infrared receiver, and the first lifting rail being on the same horizontal line as the first rail and the second rail.

[0012] By adopting the above technical solution, the first support frame provides stable installation support for each component of the feeding device, ensuring the stability of the feeding operation. The extension and retraction of the first electric push rod can drive the first lifting rail to move up and down, while the two first telescopic rods play a guiding role while the first lifting rail is rising and falling, ensuring the lifting stability of the first lifting rail. It can drive the rail trolley to descend and dock with the storage rack. Then the first electric push rod is retracted, so that the first infrared transmitter on one side of the first lifting rail corresponds to the second infrared receiver on the first rail, so that the first rail and the second rail are at the same horizontal line. Then the rail trolley can be transported along the first rail, thereby realizing the feeding and transportation of the storage rack and avoiding the workpiece falling or getting stuck during the feeding process.

[0013] Preferably, a rotating disk is fixedly connected to the bottom of the first support frame, a rotating plate is rotatably arranged on the upper end of the rotating disk, a plurality of positioning seats arranged in a rectangular array are fixedly connected to the upper end of the rotating plate, a first positioning sensor is fixedly connected to one side of the first support frame, and a second controller is fixedly connected to the inner wall of the first support frame.

[0014] By adopting the above technical solution, the rotating disk at the bottom of the first support frame provides a stable base for the rotating plate. The rotating plate can rotate flexibly around the rotating disk. First, the storage rack can be placed between the four positioning seats at the top of the rotating plate, and the workpiece can be placed inside the storage rack. Then, the rotating plate is rotated to align the storage rack with the track trolley. At this time, the positioning seat at the other end of the top of the rotating plate is close to the operator. When the track trolley aligns with the storage rack with the workpiece, the operator can load the material at the other end, improving the continuity and efficiency of the loading process. The first positioning sensor on one side of the first support frame can position the track trolley. When the first positioning sensor detects the track trolley, the detected signal can be transmitted to the first controller through the second controller, causing the track trolley to stop running and align with the storage rack, further improving the automation of the loading process, realizing the linkage between loading and conveying, and improving the convenience and accuracy of the loading operation.

[0015] Preferably, the feeding device includes a second support frame. Two second telescopic rods arranged in a mirror image are fixedly connected to the upper end of the second support frame. A second electric push rod is fixedly connected to the upper end of the second support frame. The telescopic ends of the two second telescopic rods are fixedly connected to a second lifting rail. A second infrared emitter is fixedly connected to one side of the upper end of the second lifting rail. Two side plates arranged in a mirror image are fixedly connected to the bottom end of the second support frame. A rotating shaft is rotatably connected between the two side plates. A conveyor belt is rotatably connected to the outer walls of the two rotating shafts. A support plate is fixedly connected between the side plates. The second infrared emitter corresponds to a first infrared receiver. The second lifting rail is on the same horizontal line as the first and second rails. The support plate is fixedly disposed inside the conveyor belt.

[0016] By adopting the above technical solution, the second support frame provides a solid installation support foundation for all components of the unloading device. The extension and retraction of the second electric push rod can drive the second lifting track to move up and down, while the two second telescopic rods act as guides during the lifting of the second lifting track, ensuring the stability of the lifting of the second lifting track. When the track trolley moves to the second lifting track, the second electric push rod extends to drive the storage rack to be placed at the bottom of the second support frame. The second infrared transmitter on the second lifting track corresponds precisely to the first infrared receiver on the first track, allowing the second lifting track to stop precisely at a position on the same horizontal line as the first and second tracks, realizing intelligent linkage between conveying and unloading. The side plates inside the second support frame provide stable support for the rotating shaft, and drive the conveyor belt to rotate through the rotating shaft. The support plate inside the conveyor belt plays a supporting role, ensuring the flatness of the conveyor belt during transport, allowing the workpiece rack to be transported to the subsequent workstation by the conveyor belt, improving the efficiency of unloading.

[0017] Preferably, a fixed frame is fixedly connected to one side of the inner wall of the second support frame. Two sliding rods arranged in a mirror image are fixedly connected inside the fixed frame. A threaded rod is rotatably connected inside the fixed frame. A second motor is fixedly connected to the bottom of the fixed frame. A lifting plate is threadedly connected to the outer wall of the threaded rod. Two second rotating seats arranged in a mirror image are fixedly connected to the surface of the lifting plate. A micro switch is fixedly connected to the upper end of the inner wall of each of the two second rotating seats. A rotating arm is rotatably connected inside each of the two micro switches. A reducer is fixedly connected to one side of each of the two second rotating seats. Two third motors arranged in a mirror image are fixedly connected to the surface of the lifting plate. The output ends of the two third motors are fixedly connected to the input ends of the reducers. The output ends of the two reducers are fixedly connected to the rotating arms. A second positioning sensor is fixedly connected to one side of the inner wall of the second support frame. A third controller is fixedly connected to the inner wall of the second support frame.

[0018] By adopting the above technical solution, the sliding rod inside the fixed frame guides the movement of the lifting plate. The second motor drives the threaded rod to rotate, and through the threaded transmission, the lifting plate moves smoothly up and down along the sliding rod. The second rotating seat on the lifting plate provides an installation position for the rotating arm. With the help of a micro switch, when the third motor transmits power to the rotating arm through the reducer, the rotating arm rotates flexibly. When the rotating arm touches the micro switch, the power output of the third motor stops, so that the rotating arm is at the bottom of the L-shaped buckle. The second positioning sensor on the inner wall of the second support frame can identify the position of the track trolley, so that the track trolley can accurately stop at the top of the conveyor belt. The third controller can receive the signal feedback from the second infrared transmitter and the second positioning sensor. When the storage rack is placed at the top of the conveyor belt, the second motor drives the threaded rod to rotate, and through the rotation between the threads, the lifting plate rises, so that the rotating arm contacts the L-shaped buckle and lifts the L-shaped buckle, thereby pulling the bottom of the L-shaped buckle out of the slot, thus releasing the restriction on the storage rack and releasing the storage rack. Then, through the rotation of the transmission belt, the storage rack is moved to the designated location.

[0019] Preferably, the lifting plate is slidably disposed inside the fixed frame, and both sliding rods are slidably disposed inside the lifting plate.

[0020] By adopting the above technical solution, the lifting plate is slidably set inside the fixed frame, and two sliding rods are simultaneously slidably set inside the lifting plate to form a guide and limit, so that the lifting plate remains stable when it moves up and down with the threaded rod transmission, ensuring the smoothness of the lifting process.

[0021] Preferably, the plurality of sliding wheels are rotatably disposed on the inner walls of the first and second tracks, and the outer walls of the plurality of driving wheels are in contact with the bottom ends of the first and second tracks.

[0022] By adopting the above technical solution, the sliding wheel is rotatably set on the inner wall of the first and second tracks, forming an inner rolling engagement with the tracks. The drive wheel contacts the bottom end of the first and second tracks, causing the drive wheel to rotate at the bottom end of the first and second tracks. The sliding wheel converts the friction between the track trolley and the tracks into rolling friction, reducing resistance during movement and making the movement of the track trolley smoother. The drive wheel generates driving force by contacting the bottom end of the first and second tracks, driving the track trolley to move smoothly along the tracks. This not only ensures the flexibility of the track trolley during movement but also makes the movement process smoother, avoiding jamming and deviation, reducing manual intervention, and making the entire conveying process more stable and efficient.

[0023] Preferably, one side of the bottom end of each of the L-shaped buckles is slidably disposed inside the buckle groove.

[0024] By adopting the above technical solution, the bottom side of the L-shaped buckle is slidably set inside the slot, allowing the track trolley and the storage rack to form a snap-fit ​​connection. The L-shaped buckle can slide smoothly along the slot, realizing the quick docking and separation of the track trolley and the storage rack. The operation is convenient and the connection is smooth. When the track trolley descends, the top cover at the top of the storage rack opens the L-shaped buckles on both sides. During the descent, due to the setting of the counterweight, when the bottom side of the L-shaped buckle contacts the slot, gravity causes the bottom side of the L-shaped buckle to insert into the slot, thus completing the docking between the track trolley and the storage rack. Beneficial effects

[0025] In summary, this application includes at least one of the following beneficial technical effects: This invention provides an intelligent conveying and sorting system. By setting up a conveying frame composed of a first track, a second track, and connecting rods, the first and second tracks can be freely combined and spliced ​​within the factory building via the connecting rods. This allows for the creation of a continuous conveying path to adapt to the layout requirements of different factory buildings, enabling workpieces to move smoothly between different factory buildings without the need for manual cross-area handling, significantly reducing manual operations. The rotating column, pulley frame, sliding wheels, and drive wheels at the top of the track trolley, with the sliding wheels rolling against the inner wall of the track, convert sliding friction into rolling friction, reducing resistance during movement. The contact between the drive wheels and the bottom of the track ensures that the first track... When the motor drives the drive wheel to rotate, it can drive the track trolley to move autonomously along the first and second tracks without manual traction, realizing automated transport of workpieces. At the same time, the first track serves as a temporary storage area for workpieces after loading. After the track trolley grabs the storage rack after loading the workpiece, it can rely on the positioning device integrated inside the first controller to determine the real-time position of the track trolley and accurately control multiple track trolleys to stop in an orderly manner in the designated area. The second track serves as a temporary storage area for empty track trolleys. Track trolleys that are not participating in the operation can temporarily park at the second track, realizing the orderly scheduling and reasonable allocation of track trolleys, improving the operational regularity and work efficiency of the entire system.

[0026] This invention provides an intelligent conveying and sorting system. Through the arrangement of a first telescopic rod, a first electric push rod, and a first lifting track in the feeding device, the extension and retraction of the first electric push rod drives the first lifting track up and down. The two first telescopic rods act as guides during the lifting track's movement, ensuring its stability. This allows the track trolley to descend and dock with the storage rack. Subsequently, the first electric push rod retracts, aligning a first infrared transmitter on one side of the first lifting track with a second infrared receiver on the first track, bringing the first and second tracks to the same horizontal level. The track trolley can then transport materials along the first track. Meanwhile, the second telescopic rod of the unloading device... The electric push rod and the second lifting rail are designed so that the extension and retraction of the second electric push rod can drive the second lifting rail to move up and down. The two second telescopic rods act as guides while the second lifting rail is moving up and down, ensuring the stability of the second lifting rail. At the same time, the rotating plate, rotating disk, and positioning seats of the feeding device are designed so that the storage rack can be placed between the four positioning seats on the upper part of the rotating plate, and the workpiece can be placed inside the storage rack. Then, the rotating plate is rotated to align the storage rack with the rail trolley. At this time, the positioning seat on the other end of the upper part of the rotating plate is close to the operator. When the rail trolley aligns with the storage rack with the workpiece, the operator can feed the workpiece from the other end, which improves the continuity of feeding, feeding efficiency and conveying efficiency of the device.

[0027] This invention provides an intelligent conveying and sorting system. A rotating shaft is installed inside both ends of a track trolley, with L-shaped buckles rotatably connected to the outer wall of the shaft. A counterweight is fixedly connected to one side of the upper end of each L-shaped buckle. Simultaneously, slots matching the L-shaped buckles are formed on both sides of the top cover of the storage rack. This allows for quick and stable docking between the track trolley and the storage rack. When the track trolley moves to the designated docking position of the feeding device, and the feeding device lowers the storage rack, the top cover of the storage rack first opens the L-shaped buckles on both sides. As the storage rack continues to descend, the L-shaped buckles, under the gravity of the counterweight, open further. The device rotates around a pivot, and one side of its bottom end inserts into the slots on both sides of the top cover, forming a snap-fit ​​connection with the storage rack. This allows the track trolley to dock with the storage rack without manual operation. Meanwhile, a fixed frame is fixed on one side of the inner wall of the unloading device. Inside the fixed frame, a sliding rod is fixed and a threaded rod is rotatably mounted. The bottom end of the threaded rod is connected to a second motor, and the outer wall of the threaded rod is threaded to a lifting plate. A second rotating seat is fixed on the surface of the lifting plate, and a micro switch is fixed on the upper end of the inner wall of the second rotating seat. The rotating arm is rotatably connected inside, and a third motor provides power to the rotating arm to achieve automatic release of the storage rack. After the track trolley moves the storage rack to the designated position of the unloading device, the second positioning sensor detects the position of the storage rack and transmits a signal through the third controller. The third motor drives the rotating arm to rotate through the reducer, and the second motor starts to drive the threaded rod to rotate. With the help of the threaded transmission, the lifting plate is driven to rise smoothly along the slide bar. The lifting plate drives the rotating arm to rise synchronously until the rotating arm contacts the L-shaped buckle. The rotating arm pushes the L-shaped buckle to rotate around the rotating shaft, overcoming the gravity of the counterweight and lifting the L-shaped buckle, so that one side of its bottom end is pulled out from the slot. This releases the track trolley from the storage rack and completes the automatic release of the storage rack. This automates the docking and releasing process of the device, eliminating the need for manual docking or releasing of the storage rack, reducing manual operation steps and lowering the intensity of manual labor.

Multiple connecting rods 3 arranged in a rectangular array are fixedly connected to the upper ends of the first track 1 and the second track 2. By using the first track 1 and the second track 2 as conveying tracks, they can be securely fixed to the upper part of the factory building via the connecting rods 3, facilitating the transport of workpieces to designated locations and forming a complete conveying track. This ensures the structural stability of the entire conveying device during operation. The loading device 4 and the unloading device 5 are fixedly arranged between the first track 1 and the second track 2. This arrangement allows for continuous loading, conveying, and unloading of workpieces, reducing manual handling and simplifying the workflow. Each of the multiple track trolleys 6 has a rotating shaft 10 inside at both ends, and the outer walls of the multiple rotating shafts 10 are rotatably connected to... There are L-shaped buckles 11, and counterweights 12 are fixedly connected to one side of the upper end of each of the multiple L-shaped buckles 11. Top covers 14 are fixedly connected to the upper ends of each of the multiple storage racks 13. Two slots 15 are opened on both sides of the top cover 14 and are arranged in a mirror image. The L-shaped buckles 11 are provided with rotational support by the rotating shafts 10 at both ends of the track trolley 6. The L-shaped buckles 11 can rotate flexibly around the rotating shafts 10. With the help of the gravity of the counterweights 12, they can be smoothly inserted into the slots 15 on both sides of the top cover 14 of the storage rack 13, realizing the quick docking of the track trolley 6 and the storage rack 13. At the same time, the L-shaped buckles 11 can slide smoothly in the slots 15. When the track trolley 6 moves into the unloading device 5, the unloading device 5 can lift the L-shaped buckles 11 and pull them out from the slots 15, thereby releasing the storage rack 13. The loading device 4 and the unloading device 5 facilitate the quick docking and release of the storage rack 13.

[0032] Example 2: An intelligent conveying and sorting system, referring to Figure 1 and Figure 2Each of the multiple track trolleys 6 has two rotating columns 7 fixedly connected to its upper end in a mirror-image arrangement. Each of the rotating columns 7 has a pulley frame 8 rotatably connected to its upper outer wall. Each of the pulley frames 8 has two sliding wheels 9 rotatably connected to its inner sides. Each of the multiple track trolleys 6 has a first rotating seat 16 fixedly connected to its upper end. Each of the multiple first rotating seats 16 has a first motor 17 and a first controller 18 fixedly connected to one side. Each of the multiple first rotating seats 16 has a drive wheel 19 rotatably connected inside. The output end of each of the multiple first motors 17 passes through the first rotating seat 16 and is fixedly connected to the drive wheel 19. The rotating columns 7 at the upper end of the track trolleys 6 provide fixed support for the pulley frames 8. The pulley frames 8 can rotate flexibly around the rotating columns 7, allowing for flexible direction changes when encountering turns. The contact between the sliding wheels 9 and the inner wall of the track reduces friction during the movement of the track trolleys 6, making the movement of the track trolleys 6 along the first track 1 and the second track 2 smoother and more stable, avoiding jamming. The first rotating seat 1... 6 provides a stable mounting base for the drive wheel 19 and the first motor 17. The first controller 18 can receive wireless signals from an external PLC controller, thereby controlling the first motor 17 to start. The output end of the first motor 17 drives the drive wheel 19 to rotate.

A first infrared receiver 20 is fixedly connected to one side of the upper end of the first track 1, and a second infrared receiver 21 is fixedly connected to the end of the upper end of the first track 1 away from the first infrared receiver 20. The first infrared receiver 20 and the second infrared receiver 21 on the first track 1 respectively form an inductive cooperation with the infrared transmitters of the loading device 4 and the unloading device 5, which can accurately receive infrared signals from the loading and unloading ends, realize precise positioning between the first track 1, the second track 2 and the loading device 4 and the unloading device 5, and avoid alignment deviation.

The first lifting rail 404, the first rail 1, and the second rail 2 are on the same horizontal line. The first support frame 401 provides stable installation support for all components of the feeding device 4, ensuring stable feeding operations. Qualitatively, the extension and retraction of the first electric push rod 403 can drive the first lifting rail 404 to move up and down, while the two first telescopic rods 402 act as guides while the first lifting rail 404 is rising and falling, ensuring the stability of the first lifting rail 404. This can drive the rail trolley 6 to descend and dock with the storage rack 13. Then, the first electric push rod 403 is retracted, so that the first infrared transmitter 405 on one side of the first lifting rail 404 corresponds to the second infrared receiver 21 on the first rail 1, so that the first rail 1 and the second rail 2 are at the same horizontal line. Then, the rail trolley 6 can be transported along the first rail 1, thereby realizing the loading and transportation of the storage rack 13, and avoiding the workpiece falling or getting stuck during the loading process.

A first positioning sensor 409 is fixedly connected to one side of the first support frame 401. A second controller 410 is fixedly connected to the inner wall of the first support frame 401. The rotating disk 406 at the bottom of the first support frame 401 provides a stable base for the rotating plate 407 to rotate. The rotating plate 407 can rotate flexibly around the rotating disk 406. The storage rack 13 can be placed between the four positioning seats 408 on the upper end of the rotating plate 407, and the workpiece can be placed inside the storage rack 13. Then the rotating plate can be rotated. 407 aligns the storage rack 13 with the track trolley 6. At this time, the positioning seat 408 at the other end of the upper part of the rotating plate 407 is close to the operator. When the track trolley 6 aligns with the storage rack 13 on which the workpiece has been placed, the operator can load the workpiece at the other end, improving the continuity and efficiency of the loading process. The first positioning sensor 409 on one side inside the first support frame 401 can position the track trolley 6. When the first positioning sensor 409 detects the track trolley 6, it can transmit the detected signal to the first controller 18 through the second controller 410, causing the track trolley 6 to stop running and align the track trolley 6 with the storage rack 13, further improving the automation of the loading process, realizing the linkage between loading and conveying, and improving the convenience and accuracy of the loading operation.

A rotating shaft 507 is rotatably connected between each of the two side plates 506. A conveyor belt 509 is rotatably connected to the outer walls of the two rotating shafts 507. A support plate 508 is fixedly connected between the side plates 506. The second infrared emitter 505 corresponds to the first infrared receiver 20. The second lifting rail 504 is connected to the first rail... The first and second tracks 1 and 2 are on the same horizontal line. The support plate 508 is fixedly installed inside the conveyor belt 509. The second support frame 501 provides a solid installation support base for all components of the unloading device 5. The extension and retraction of the second electric push rod 503 can drive the second lifting track 504 to move up and down. The two second telescopic rods 502 play a guiding role while the second lifting track 504 is rising and falling, ensuring the stability of the second lifting track 504. When the track trolley 6 moves to the second lifting track 504, the second electric push rod 503 extends and drives the storage rack 13 to be placed at the bottom of the second support frame 501. The second infrared transmitter 505 on the second lifting track 504 corresponds precisely to the first infrared receiver 20 of the first track 1, so that the second lifting track 504 can be accurately stopped at a position on the same horizontal line as the first track 1 and the second track 2, realizing intelligent linkage between conveying and unloading. The side plate 506 inside the second support frame 501 provides stable support for the rotating shaft 507 and drives the conveyor belt 509 to rotate through the rotating shaft 507. The support plate 508 inside the conveyor belt 509 plays a supporting role, ensuring the flatness of the conveyor belt 509 during transportation, so that the workpiece rack can be transported to the subsequent station through the conveyor belt 509, thereby improving the efficiency of material unloading.

Two sliding rods 511 arranged in a mirror image are fixedly connected inside the fixed frame 510. A threaded rod 512 is rotatably connected inside the fixed frame 510. A second motor 513 is fixedly connected to the bottom end of the fixed frame 510. A lifting plate 514 is threadedly connected to the outer wall of the threaded rod 512. Two second rotating seats 515 arranged in a mirror image are fixedly connected to the surface of the lifting plate 514. A micro switch 516 is fixedly connected to the upper end of the inner wall of each of the two second rotating seats 515. A rotating... Arm 517, and two second rotating seats 515 are each fixedly connected to one side of a reducer 518. Two third motors 519 are fixedly arranged in a mirror image on the surface of the lifting plate 514. The output ends of the two third motors 519 are fixedly connected to the input ends of the reducers 518. The output ends of the two reducers 518 are fixedly connected to the rotating arm 517. A second positioning sensor 520 is fixedly connected to one side of the inner wall of the second support frame 501. A third controller 521 is fixedly connected to the inner wall of the second support frame 501. The slide rod 511 inside the fixed frame 510 guides the movement of the lifting plate 514. 513 is used to drive the threaded rod 512 to rotate, which in turn drives the lifting plate 514 to rise and fall smoothly along the slide rod 511 via threaded transmission. The second rotating seat 515 on the lifting plate 514 provides an installation position for the rotating arm 517. In conjunction with the micro switch 516, when the third motor 519 transmits power to the rotating arm 517 through the reducer 518, the rotating arm 517 rotates flexibly. When the transmission arm touches the micro switch 516, the power output of the third motor 519 is stopped, so that the rotating arm 517 is at the bottom of the L-shaped buckle 11. The second positioning sensor 520 on the inner wall of the second support frame 501 can identify the position of the track trolley 6, so that... The track trolley 6 can accurately stop at the top of the conveyor belt 509. The third controller 521 can receive signal feedback from the second infrared transmitter 505 and the second positioning sensor 520. When the storage rack 13 is placed on the top of the conveyor belt 509, the second motor 513 drives the threaded rod 512 to rotate. The rotation between the threads drives the lifting plate 514 to rise, so that the rotating arm 517 contacts the L-shaped buckle 11 and lifts the L-shaped buckle 11. Then, the bottom end of the L-shaped buckle 11 is pulled out of the slot, thereby releasing the restriction on the storage rack 13 and releasing the storage rack 13. Then, through the rotation of the transmission belt, the storage rack 13 is moved to the designated location.

[0037] Reference Figure 6The lifting plate 514 is slidably disposed inside the fixed frame 510, and the two sliding rods 511 are slidably disposed inside the lifting plate 514. By slidably disposing the lifting plate 514 inside the fixed frame 510 and simultaneously disposing the two sliding rods 511 inside the lifting plate 514, a guide and limit are formed, so that the lifting plate 514 remains stable when it moves up and down with the transmission of the threaded rod 512, ensuring the smoothness of the lifting process.

[0038] Reference Figure 1 and Figure 3 Multiple sliding wheels 9 are rotatably disposed on the inner walls of the first track 1 and the second track 2. The outer walls of multiple driving wheels 19 contact the bottom ends of the first track 1 and the second track 2. The sliding wheels 9 rotatably disposed on the inner walls of the first track 1 and the second track 2, forming an inner rolling engagement with the tracks. The driving wheels 19 contact the bottom ends of the first track 1 and the second track 2, causing the driving wheels 19 to rotate at the bottom ends of the first track 1 and the second track 2. The sliding wheels 9 convert the friction between the track trolley 6 and the tracks into rolling friction, reducing resistance during movement and making the movement of the track trolley 6 smoother. The driving wheels 19 generate driving force through contact with the bottom ends of the first track 1 and the second track 2, driving the track trolley 6 to move smoothly along the tracks. This ensures both the flexibility of the track trolley 6 during movement and a smoother movement process, avoiding any slippage. To minimize jamming and misalignment, and reduce manual intervention, the entire conveying process is made more stable and efficient. Multiple L-shaped buckles 11 are slidably positioned on one side of their bottom end within the slot 15, allowing the track trolley 6 and storage rack 13 to engage. The L-shaped buckles 11 can slide smoothly along the slot 15, enabling rapid docking and separation between the track trolley 6 and storage rack 13. The operation is convenient and the connection is smooth. When the track trolley 6 descends, the top cover 14 at the top of the storage rack 13 opens the L-shaped buckles 11 on both sides. During descent, due to the counterweight 12, when one side of the L-shaped buckle 11 contacts the slot 15, gravity causes the bottom side of the L-shaped buckle 11 to insert into the slot, thus completing the docking between the track trolley 6 and the storage rack 13.

[0039] The implementation principle of this application embodiment is as follows: First, the first track 1 and the second track 2 are freely combined and spliced ​​inside the factory building through the connecting rod 3 to build a continuous conveying path adapted to the factory layout. The first track 1 serves as a temporary storage area after the workpiece is loaded, and the second track 2 serves as a temporary storage area for the empty track trolley 6, realizing the orderly scheduling of the track trolley 6. During loading, the operator places the storage rack 13 between the positioning seats 408 on the upper end of the rotating plate 407 and places the workpiece inside the storage rack 13. Then, the rotating plate 407 is rotated so that the storage rack 13 is aligned with the track trolley 6 at the loading device 4. At the same time, after the first positioning sensor 409 detects the track trolley 6, it is controlled by the second controller 4. 10 transmits the signal to the first controller 18, controlling the track trolley 6 to stop running and align with the storage rack 13. Then, the first electric push rod 403 starts to extend and retract, driving the first lifting track 404 to move up and down. The two first telescopic rods 402 play a guiding role, ensuring that the first lifting track 404 descends smoothly, driving the track trolley 6 to dock with the storage rack 13. During docking, the top cover 14 of the storage rack 13 first pushes open the L-shaped buckles 11 at both ends of the track trolley 6. As the storage rack 13 continues to descend, the L-shaped buckles 11 rotate around the rotating shaft 10 under the gravity of the counterweight 12, and one side of the bottom end inserts into the slot 15 of the top cover 14 of the storage rack 13, completing the automatic locking and docking of the track trolley 6 and the storage rack 13. After docking is completed, the first electric push rod 403 is retracted, and the first lifting rail 404 is adjusted to the same horizontal line as the first rail 1 and the second rail 2. The first infrared transmitter 405 on the first lifting rail 404 and the second infrared receiver 21 on the first rail 1 are inductively coordinated to achieve alignment. Then the first controller 18 receives the wireless signal sent by the external PLC controller and controls the first motor 17 to start. The output end of the first motor 17 drives the drive wheel 19 to rotate. The drive wheel 19 contacts the bottom end of the rail to generate driving force. At the same time, the sliding wheel 9 on the upper end of the rail trolley 6 rolls with the inner wall of the rail to convert sliding friction into rolling friction to reduce movement resistance. The pulley frame 8 can rotate flexibly around the rotating column 7 to ensure that the rail trolley 6 can flexibly adjust its direction when turning, driving the storage rack 13 and the workpiece to move smoothly along the first rail 1 to realize the automated conveying of the workpiece. Multiple rail trolleys 6 can be orderly parked in the designated temporary storage area of ​​the first rail 1 according to the positioning device integrated inside the first controller 18. When the trolley 6 moves the storage rack 13 to the unloading device 5, the second infrared transmitter 505 on the second lifting track 504 and the first infrared receiver 20 on the first track 1 sense and cooperate, controlling the trolley 6 to stop at the second lifting track 504. Then, the second electric push rod 503 is activated, driving the second lifting track 504 to descend smoothly, conveying the storage rack 13 onto the conveyor belt 509 inside the unloading device 5. The second telescopic rod 502 acts as a guide, ensuring the smooth lifting of the second lifting track 504. At this time, the second positioning sensor 520 detects the position of the storage rack 13 and transmits a signal through the third controller 521. The third motor 519 then drives the reducer 5... 18 drives the rotating arm 517 to rotate until the rotating arm 517 contacts the micro switch 516. Then, the second motor 513 starts to drive the threaded rod 512 to rotate. With the help of the threaded transmission, the lifting plate 514 is driven to rise smoothly along the slide rod 511. The slide rod 511 plays a guiding and limiting role on the lifting plate 514 to ensure smooth lifting process. The lifting plate 514 drives the rotating arm 517 to rise synchronously until the rotating arm 517 contacts the L-shaped buckle 11. The rotating arm 517 pushes the L-shaped buckle 11 to rotate around the rotating shaft 10, overcoming the gravity of the counterweight 12 to lift the L-shaped buckle 11, so that one side of its bottom end is pulled out from the slot 15, releasing the limit on the storage rack 13 and completing the automatic release of the storage rack 13. After being released, the storage rack 13 falls onto the conveyor belt 509. The side plate 506 provides fixed support for the rotating shaft 507, which drives the conveyor belt 509 to rotate. The support plate 508 inside the conveyor belt 509 provides support to ensure the smooth transport of the conveyor belt 509. The storage rack 13 and the workpiece are then transported to the designated work station to complete the unloading operation. After unloading, the empty track trolley 6 moves along the track to the second track 2 under the drive of the first motor 17 for temporary storage, waiting for the next operation. The entire process requires minimal human intervention, ensuring smooth and efficient operation.
