Description

Technical Field

[0001] This invention relates to the field of automated painting line hoisting technology, and in particular to an automatic painting line hoisting device. Background Technology

[0002] An automatic spray painting line is a modern spray painting equipment that integrates pretreatment, drying, spraying, curing, automated conveying systems and computer control technologies. It is widely used in various industrial fields to provide high-quality surface coatings for products. For example, spraying paint on components in laboratory equipment can play a role in protection and aesthetics.

[0003] Currently, suspended automatic painting lines are generally used to transport and paint the objects to be painted. Before transport, a hoist is usually used to hang the objects to be painted on the transport line of the automatic painting line, and then the transport line transports the objects to be painted to the painting station.

[0004] However, in production practice, it is necessary to first pre-install the lifting equipment on the transport line, and then hang the object to be sprayed on the lifting equipment. Both of these steps require different operators to perform the operations in a specific time sequence, which results in high labor costs. Moreover, since the transport line is in continuous motion, operators are prone to fatigue from coordinating the operation of hanging the lifting equipment and hanging the object to be sprayed for a long time. In particular, when the rhythm of hanging the lifting equipment does not follow the continuous movement of the track, the operation of hanging the object to be sprayed cannot be carried out smoothly, which in turn affects the production progress. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic painting line hanger loading device, which aims to automatically load the hanger onto the painting production line, reduce personnel requirements, and improve loading efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] This invention provides an automatic painting line hanger loading device. The automatic painting line includes a transport line with first mounting parts spaced apart along its extension direction for mounting hangers. Each end of the hanger has a first hook and a second hook capable of engaging with the first mounting parts. The automatic painting line hanger loading device includes a cylindrical cylinder, a transport trough, a pushing mechanism, a mounting assembly, and a collecting assembly. The cylindrical cylinder has a first receiving cavity, a first opening communicating with the first receiving cavity, a second receiving cavity, and a second opening communicating with the second receiving cavity. The hanger is engaged within the first receiving cavity. The first hooks are located outside the first receiving cavity and close to the first opening. The transport trough is used to hold the cylindrical cylinder and has an inlet end, an outlet end, and a guide groove matching the second hooks. The pushing mechanism is used to push the cylindrical cylinder from the feed end to the discharge end. The mounting assembly is located on the discharge end side and is used to movably connect the cylindrical cylinder conveyed from the transport trough. The collecting assembly includes a third hook, a trigger assembly, and a first driving mechanism. The third hook is movably located in the second receiving cavity. The trigger assembly is located in the second receiving cavity and is drivenly connected to the third hook. The first driving mechanism has a second mounting part that can be hooked with the third hook to drive the cylindrical cylinder to detach from the mounting assembly. When the first mounting part hooks the second hook, the cylindrical cylinder rotates relative to the mounting assembly. When the second hook moves out of the first receiving cavity, the trigger assembly drives the third hook to extend out of the second receiving cavity from the second opening. When the cylindrical cylinder rotates from an inclined state to a vertical state, the third hook is hooked on the second mounting part.

[0008] In addition, the automatic painting line hanger automatic loading device according to the present invention may also have the following additional technical features:

[0009] Furthermore, the mounting assembly includes a surrounding plate, a first rotating shaft, an opening and closing mechanism, and two sets of clamping plate assemblies. The surrounding plate is provided with a clearance hole matching the discharge end. The first rotating shaft is rotatably mounted on the surrounding plate and located within the surrounding area of ​​the surrounding plate. The rotation axis of the first rotating shaft is parallel to the discharge direction of the discharge end. The side wall of the cylindrical cylinder is provided with a locking interface that cooperates with the first rotating shaft, and a sliding groove that communicates with the locking interface and matches the width of the first rotating shaft. The sliding groove extends to the end of the cylindrical cylinder near the first opening side. The opening and closing mechanism is located in the locking interface and is used to lock and separate the locking interface from the first rotating shaft. The two sets of clamping plate assemblies are arranged opposite each other and clamp the cylindrical cylinder along the discharge direction parallel to the discharge end. When the cylindrical cylinder rotates relative to the surrounding plate, the two sets of clamping plate assemblies move closer to each other or further away from each other. When the third hook is mounted on the second mounting part, the opening and closing mechanism separates the locking interface from the first rotating shaft under the action of the first driving mechanism, and the first rotating shaft moves along the extension direction of the sliding groove until it moves out of the locking interface.

[0010] Furthermore, the third hook is slidably disposed within the second receiving cavity. The third hook is equipped with a locking block. The triggering assembly includes opposing locking plates, a first elastic element, opposing stop bars, and a second elastic element. Both locking plates are rotatably disposed on the cylindrical body and are located within the second receiving cavity. The locking plates have a wedge-shaped edge at one end near the second opening, and a locking groove matching the locking block is provided on the outer wall of the locking plates near the wedge-shaped edge. The two ends of the first elastic element are respectively connected to the locking plates and located between the two locking plates. The two stop bars are slidably disposed on the cylindrical body, with one end of each stop bar extending into the first receiving cavity and the other end of each stop bar extending into the second receiving cavity and connected to the end of the locking plates near the second opening. The second elastic element is disposed between the cylindrical body and the stop bars and is connected to the stop bars. When the portions of the two locking plates extending into the first receiving cavity abut against each other, the locking block engages in the locking groove, and both the first and second elastic elements are in a natural state. When the portions of the two locking plates extending into the first receiving cavity separate, the locking block disengages from the locking groove, and the first elastic element is in a compressed state, while the second elastic element is in a stretched state.

[0011] Furthermore, the clamping plate assembly includes a clamping plate and a third elastic member. The clamping plate is slidably disposed on the surrounding plate and is parallel to the discharge direction of the discharge end. The two ends of the third elastic member are respectively fixed to the surrounding plate and the clamping plate to drive the clamping plate to clamp the cylindrical tube.

[0012] Furthermore, the opening and closing mechanism includes opposing clamping arms and opposing fourth elastic elements. Both clamping arms are rotatably mounted on the cylindrical tube and rotate coaxially. One end of each of the two fourth elastic elements is fixed to the cylindrical tube, and the other end of each of the two fourth elastic elements is fixed to the clamping arms. When the two clamping arms are closed to clamp the cylindrical tube, and when the two clamping arms are opened and closed to form a clearance space matching the width of the first rotating shaft, the fourth elastic elements are in a stretched state.

[0013] Furthermore, an auxiliary push-pull structure is provided between the clamping plate and the first rotating shaft, which is used to drive the two sets of clamping plates closer to each other when the cylindrical tube rotates relative to the surrounding plate. The auxiliary push-pull structure includes meshing gears, torsion springs, and parallel rows of teeth. The first rotating shaft is sleeved on one of the gears, and the torsion spring is located between one of the gears and the first rotating shaft to provide a resisting force to prevent the first rotating shaft from rotating when it rotates relative to the surrounding plate. The rows of teeth are slidably located on the surrounding plate and connected to the clamping plate. The two rows of teeth are respectively located on both sides of the gears and are meshed with the two gears respectively.

[0014] Furthermore, the bottom of the transport trough is provided with a clearance groove. The pushing mechanism includes a pushing head, a telescopic mechanism, and a lifting mechanism. The telescopic mechanism is connected to the pushing head to drive the pushing head to move horizontally along the extension direction of the clearance groove. The lifting mechanism is connected to the telescopic mechanism to drive the telescopic mechanism to approach the transport trough until the pushing head passes through the clearance groove and partially extends into the transport trough, or to drive the telescopic mechanism away from the transport trough until the pushing head moves out of the clearance groove.

[0015] Furthermore, the transport line includes a track, a circulating cable chain, and a swing damping mechanism. The circulating cable chain is mounted on the track, and the swing damping mechanism is mounted on the circulating cable chain. The swing damping mechanism includes a first mounting bracket, a second rotating shaft, a second mounting bracket, a first friction plate, a second friction plate, and an anti-detachment hook. The first mounting bracket is fixed to the circulating cable chain, the second rotating shaft is rotatably mounted on the first mounting bracket, and the second mounting bracket is sleeved on the second rotating shaft. One end of the first friction plate is rotatably mounted on the second rotating shaft, and the other end of the first friction plate is fixed to the first mounting bracket. One end of the second friction plate is sleeved on the second rotating shaft and abuts against the first friction plate, and the other end of the second friction plate is fixed to the second mounting bracket. The anti-detachment hook is fixed to the second mounting bracket.

[0016] Furthermore, the automatic painting line hanger automatic loading device also includes an automatic feeding mechanism, which includes a material trough, a slide bar, a push bar, a second drive mechanism, and a robotic arm. The material trough is provided with a discharge channel, which has an inclined section and a straight section. The straight section has a clamping groove. The slide bar is located on the material trough, and the extension path of the slide bar matches that of the inclined section and the straight section. The second hook is hooked onto the slide bar. The push bar is provided with a push head, and the push head has a limiting groove that matches the height of the second hook head. The second drive mechanism is used to push the push bar to move back and forth along the clamping groove. The robotic arm is used to change the cylindrical cylinder from a horizontal state to a vertical state and place it at the feeding end.

[0017] The beneficial effects of this invention include at least the following: by clamping the lifting device inside a cylindrical tube, it facilitates transmission via a transport trough. Simultaneously, by combining the dynamic attachment characteristics of the first mounting part on the transport line, the lifting device is smoothly extracted from the cylindrical tube dynamically via the mounting assembly. Finally, the cylindrical tube is collected by a collecting assembly to facilitate the extraction of the lifting device from the next cylindrical tube. Compared to existing technologies, this eliminates the need for operators to mount the lifting device and allows for continuous mounting operations following the movement of the track, reducing labor costs and minimizing the impact of mounting the lifting device on the operation of mounting the object to be sprayed.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] Please refer to Figures 1 to 11This invention provides an automatic painting line hanger loading device. The automatic painting line includes a transport line 100, with first mounting parts for hanging hangers 200 spaced apart along its extension direction. Each end of the hanger 200 along its length is provided with a first hook 210 and a second hook 220 capable of engaging with the first mounting parts. The first hook 210 is used to hang the object to be painted. The automatic painting line hanger loading device includes a cylindrical cylinder 300, a transport trough 400, a pushing mechanism 500, a hanging assembly 600, and a collecting assembly 700.

[0044] The cylindrical tube 300 has a first receiving cavity 310, a first opening 320 communicating with the first receiving cavity 310, a second receiving cavity 330, and a second opening 340 communicating with the second receiving cavity 330. The lifting device 200 is assembled inside the cylindrical tube 300. Specifically, the lifting device 200 is engaged inside the first receiving cavity 310, and the second hook 220 is located outside the first receiving cavity 310 and close to the first opening 320.

[0045] The transport trough 400 is used to hold the cylindrical cylinder 300. The transport trough 400 is provided with a feed end 410 and a discharge end 420, as well as a guide groove 430 that matches the second hook 220. When the cylindrical cylinder 300 enters the transport trough 400 from the feed end 410, the second hook 220 is limited to move in the guide groove 430 to prevent the cylindrical cylinder 300 from rotating.

[0046] The pushing mechanism 500 is used to push the cylindrical cylinder 300 from the feed end 410 to the discharge end 420, so that the cylindrical cylinder 300 carried in the transport trough 400 is moved out from the discharge end 420 in sequence.

[0047] The mounting assembly 600 is located on the discharge end 420 side and is used to movably connect the cylindrical cylinder 300 conveyed from the transport trough 400. Specifically, the cylindrical cylinder 300 can rotate relative to the mounting assembly 600, and after applying a certain amount of force, the cylindrical cylinder 300 can be separated from the mounting assembly 600. Thus, when the first mounting part is mounted on the second hook 220, the moving first mounting part can drive the cylindrical cylinder 300 to deflect, so that when the first mounting part continues to move away from the cylindrical cylinder 300, the lifting device 200 can be smoothly pulled out from the first receiving cavity 310. At the same time, by applying force, the cylindrical cylinder after being removed from the lifting device 200 is separated from the mounting assembly 600 so that the next cylindrical cylinder 300 can be movably mounted on the mounting assembly 600.

[0048] The collecting assembly 700 includes a third hook 710, a trigger assembly 720, and a first drive mechanism 730. The third hook 710 is movably disposed within the second receiving cavity 330. Specifically, when the cylindrical tube 300 is transported in the transport trough 400, the third hook 710 can be completely housed within the second receiving cavity 330 to avoid affecting transport. When collecting the cylindrical tube 300 to prepare for the attachment of the next cylindrical tube 300, the third hook 710 moves out of the second receiving cavity 330 to separate the cylindrical tube 300 from the mounting assembly 600. The trigger assembly 720 is disposed within the second receiving cavity 330 and is drively connected to the third hook 710. The first drive mechanism 730 has a second mounting portion that can engage with the third hook 710. When the first drive mechanism 730 is in operation, it detaches the cylindrical tube 300 from the mounting assembly 600 through the engagement of the second mounting portion with the third hook 710. Optionally, the first drive mechanism 730 may be a telescopic motor, and a hanging ring for attaching the third hook 710 may be provided on the telescopic shaft of the telescopic motor.

[0049] In this embodiment, when the first mounting part attaches the second hook 220, the first mounting part pulls the cylindrical cylinder 300 to rotate relative to the mounting assembly 600. At this time, the cylindrical cylinder 300 changes from a vertical state to an inclined state. Simultaneously, the first mounting part gradually pulls the cylindrical cylinder 300 out of the first receiving cavity 310 through the second hook 220. Specifically, as the lifting device 200 is gradually pulled out of the first receiving cavity 310, the first hook 210 gradually approaches the trigger assembly 720. At this time, the trigger assembly 720 is in a locked state for the third hook 710. When the first hook 210 passes the trigger assembly 720, the trigger assembly 720 is in a state of separating the third hook 710. Under the action of gravity, the third hook 710 extends out of the second receiving cavity 330 from the second opening 340. When the lifting device 200 is pulled out of the first receiving cavity 310, under the combined action of gravity and the mounting assembly 600, the cylindrical cylinder 300 rotates from an inclined state to a vertical state. When the cylindrical cylinder 300 rotates to a vertical state, the third hook 710 is mounted on the second mounting part. Then the first drive mechanism 730 is activated and applies force until the cylindrical cylinder 300 is detached from the mounting assembly 600.

[0050] In some alternative embodiments, such as Figures 2 to 4 , Figure 7 As shown, the mounting assembly 600 includes a surrounding plate 610, a first rotating shaft 620, an opening and closing mechanism 630, and two sets of clamping plate assemblies 640.

[0051] The enclosure 610 has a clearance hole 611 that matches the discharge end 420, allowing the cylindrical cylinder 300 to smoothly pass through the clearance hole 611 and enter the area enclosed by the enclosure 610. A first rotating shaft 620 is rotatably mounted on the enclosure 610 and is located within the area enclosed by the enclosure 610. Furthermore, the rotation axis of the first rotating shaft 620 is parallel to the discharge direction of the discharge end 420. The side wall of the cylindrical cylinder 300 has a locking interface 350 that mates with the first rotating shaft 620. When the cylindrical cylinder 300 enters the area enclosed by the enclosure 610 through the clearance hole 611, the first rotating shaft 620 is engaged within the locking interface 350. Meanwhile, the side wall of the cylindrical cylinder 300 is also provided with a groove 360 ​​communicating with the card interface 350. The width of the groove 360 ​​matches that of the first rotating shaft 620, and the groove 360 ​​extends to the end of the cylindrical cylinder 300 near the first opening 320. Thus, after the first rotating shaft 620 contacts and engages with the card interface 350, the first rotating shaft 620 can be moved out of the card interface 350 through the groove 360, achieving the purpose of disengaging the cylindrical cylinder 300. The opening and closing mechanism 630 is provided inside the card interface 350 and is used to lock and separate the card interface 350 from the first rotating shaft 620. Two sets of clamping plate assemblies 640 are arranged opposite to each other, and the two sets of clamping plate assemblies 640 cooperate with each other to clamp the cylindrical cylinder 300 in the discharge direction parallel to the discharge end 420. This allows the cylindrical cylinder 300 to be clamped by the clamping plate assemblies 640 after entering the area enclosed by the surrounding plate 610 through the clearance hole 611. This prevents the impact force generated when the first mounting part hangs the second hook 220 from causing the cylindrical cylinder 300 to deviate from its position, thereby causing the hanging failure.

[0052] In this embodiment, when the cylindrical cylinder 300 rotates relative to the surrounding plate 610, the two sets of clamping plate assemblies 640 move closer to or further away from each other. Specifically, when the second hook 220 is attached to the first mounting part, the cylindrical cylinder 300 changes from a vertical state to an inclined state. The cylindrical cylinder 300 applies a pushing force to the two sets of clamping plate assemblies 640 on both sides. Under the action of this pushing force, the two sets of clamping plate assemblies 640 move further away from each other, but the two sets of clamping plate assemblies 640 always clamp the cylindrical cylinder 300 in the discharge direction parallel to the discharge end 420 to ensure the stability of the attachment process. When the lifting device 200 is pulled out from the first receiving cavity 310, the cylindrical cylinder 300 changes from a vertical state to an inclined state. Since the first mounting part does not apply a force to the cylindrical cylinder 300, thus... Under the combined action of the cylinder 300's own gravity and the clamping force of the two sets of clamping plate assemblies 640, the two sets of clamping plate assemblies 640 move closer to each other until the cylinder 300 changes from an inclined state to a vertical state. When the cylinder 300 is in a vertical state, the third hook 710 is attached to the second mounting part. Then, under the action of the first drive mechanism 730, the opening and closing mechanism 630 separates the card interface 350 from the first rotating shaft 620. Thus, the first rotating shaft 620 moves along the extension direction of the slide groove 360 ​​until it moves out of the card interface 350. At this time, the cylinder 300 is detached from the surrounding plate 610. Preferably, in order to ensure that the card interface 350 and the first rotating shaft 620 can always remain relatively stationary, the card interface 350 can be set into a polygonal shape, such as a quadrilateral card interface 350, and a corresponding polygonal snap-fit ​​area can be set on the first rotating shaft 620.

[0053] In addition, it should be noted that by reasonably setting the depth of the card interface 350, the front end of the first rotating shaft 620 can be inserted into the outermost edge of the card interface 350 before the cylindrical cylinder 300 has fully entered the area enclosed by the surrounding plate 610 from the clearance hole 611, thereby ensuring that the first rotating shaft 620 is accurately inserted into the card interface 350.

[0054] Furthermore, it should be noted that during the process of the cylindrical cylinder 300 entering the area enclosed by the surrounding plate 610 through the clearance hole 611, the cylindrical cylinder 300 may rotate, which may cause the second hook 220 on the cylindrical cylinder 300 to fail to align with the first mounting part to be attached, and the third hook 710 on the cylindrical cylinder 300 to fail to align with the second mounting part to be attached. Therefore, the guide groove 430 extends a portion towards the surrounding plate 610, the length of which is equal to the thickness of the clearance hole 611. At the same time, in order for the cylindrical cylinder 300 to be smoothly engaged on the first rotating shaft 620, the area enclosed by the surrounding plate 610 matches the diameter of the cylindrical cylinder 300.

[0055] In some alternative embodiments, such as Figure 8As shown, the third hook 710 is slidably disposed within the second receiving cavity 330. Optionally, a groove (not shown in the figures) can be provided on the inner wall of the second receiving cavity 330. The third hook 710 is limited within the groove and can move within the groove. The third hook 710 is provided with a locking block 711. The triggering assembly 720 includes a locking plate 721, a first elastic member 722, a stop bar 723, and a second elastic member 724 disposed opposite to each other.

[0056] Both clamping plates 721 are rotatably mounted on the cylindrical cylinder 300 and are located within the second receiving cavity 330. Each clamping plate 721 has a wedge-shaped edge 7211 at its end near the second opening 340, and a groove 7212 matching the clamping block 711 is provided on the outer wall of the clamping plate 721 near the wedge-shaped edge 7211. The two ends of a first elastic member 722 are respectively connected to the two clamping plates 721, and the first elastic member 722 is located between the two clamping plates 721. Two stop rods 723 are slidably mounted on the cylindrical cylinder 300. Optionally, a shaft hole (not shown in the figures) can be provided on the cylindrical cylinder 300, and the middle part of the stop rod 723 can pass through the shaft hole. Simultaneously, one end of each of the two stop rods 723 extends into the first receiving cavity 310, and the other end of each of the two stop rods 723 extends into the second receiving cavity 330. The portions of the two stop rods 723 located in the second receiving cavity 330 are connected to the end of the clamping plate 721 near the second opening 340. The second elastic element 724 is disposed between the cylindrical cylinder 300 and the stop rod 723, and is connected to the stop rod 723, so that the second elastic element 724 can change its state during the sliding process of the stop rod 723. Optionally, both the first elastic element 722 and the second elastic element 724 can be made of elastic elements such as springs or spring sheets. For example, when a spring is used, the spring is disposed between the cylindrical cylinder 300 and the stop rod 723, and the spring is sleeved on the sliding rod of the stop rod 723.

[0057] In this embodiment, when the first hook 210 does not push against the two stop bars 723, the portions of the two stop bars 723 extending into the first receiving cavity 310 abut against each other. At this time, the first elastic member 722 and the second elastic member 724 are both in their natural state, and the locking block 711 is engaged in the locking groove 7212, so that the third hook head 710 is completely in the second receiving cavity 330. When the first hook 210 pushes against the two stop bars 723, the portions of the two stop bars 723 extending into the first receiving cavity 310 receive the pushing force and abut against each other. When separated, the stop lever 723 pushes the two clamping plates 721 to rotate. This pushing force causes the portions of the clamping plates 721 near the wedge-shaped edge 7211 to move closer together. The first elastic element 722 is compressed, and the second elastic element 724 is stretched. Meanwhile, the portions of the clamping plates 721 away from the stop lever 723 move away from each other. At this time, the clamping block 711 disengages from the clamping groove 7212. Under the action of gravity, the third hook 710 slides in the second receiving cavity 330 and moves away from the clamping plate 721. Thus, the third hook 710 moves out of the second receiving cavity 330. As the first hook 210 gradually moves away from the stop bar 723, the portions of the two stop bars 723 that extend into the first receiving cavity 310 re-abut against each other. At this time, the first elastic element 722 and the second elastic element 724 return to their natural state. The end of the third hook 710 near the second receiving cavity 330 is blocked by the wedge-shaped edge 7211, thus maintaining its fixed position. When an external force is applied to the third hook 710, the third hook 710 moves into the second receiving cavity 330, simultaneously pressing the wedge-shaped edge 721. 1. The squeezing force pushes the two clamping plates 721 to rotate, causing the portions of the clamping plates 721 near the wedge-shaped edge 7211 to move closer to each other. The first elastic element 722 is compressed and the second elastic element 724 is stretched until the clamping block 711 moves to the slot 7212. At this time, under the action of the first elastic element 722 and the second elastic element 724, the two clamping plates 721 rotate in opposite directions until the clamping block 711 engages in the slot 7212. At the same time, the portions of the two stop rods 723 that extend into the first receiving cavity 310 abut against each other again.

[0058] In some alternative embodiments, such as Figure 4 As shown, the clamping plate assembly 640 includes a clamping plate 641 and a third elastic element 642. The clamping plate 641 is parallel to the discharge direction of the discharge end 420 to better clamp the cylindrical cylinder 300. The two ends of the third elastic element 642 are fixed to the surrounding plate 610 and the clamping plate 641, respectively. When the cylindrical cylinder 300 is not clamped by the two clamping plates 641, the third elastic element 642 is in a natural state. When the cylindrical cylinder 300 is clamped by the two clamping plates 641, the third elastic element 642 is in a compressed state under the squeezing action of the cylindrical cylinder 300, so that the cylindrical cylinder 300 is always tightly clamped between the two clamping plates 641. Optionally, the third elastic element 642 can be a spring, a sheet spring, or other elastic element.

[0059] Furthermore, in order to ensure that the two clamping plates 641 can smoothly approach and move away from each other, and to prevent swaying during the movement of the clamping plates 641, which would cause the clamping plates 641 to be no longer parallel to the discharge direction of the discharge end 420 and thus hinder the rotation of the cylindrical cylinder 300, the clamping plates 641 are slidably mounted on the surrounding plate 610. Optionally, a groove (not shown in the figures) can be provided on the inner sidewall of the surrounding plate 610, and the clamping plates 641 are confined within the groove and can move within the groove.

[0060] In some alternative embodiments, such as Figure 7 As shown, the opening and closing mechanism 630 includes opposing clamping arms 631 and opposing fourth elastic members 632. Both clamping arms 631 are rotatably mounted on the cylindrical cylinder 300, and their rotation axes coincide. One end of each of the two fourth elastic members 632 is fixed to the cylindrical cylinder 300, and the other end is fixed to each of the two clamping arms 631. When the two clamping arms 631 are closed, a clamping area is formed in the middle of the two clamping arms 631. This clamping area matches the outer dimensions of the first rotating shaft 620, and the fourth elastic member 632 is in a stretched state at this time. When the two clamping arms 631 are open or closed, they form a clearance space that matches the width of the first rotating shaft 620. At this time, the fourth elastic member 632 is still in a stretched state, but the degree of stretching of the fourth elastic member 632 is reduced. When the force applied to the cylindrical cylinder 300 by the first driving mechanism is greater than the tensile force of the fourth elastic element 632 when the two clamping arms 631 open and close, the first rotating shaft 620 pushes open the two clamping arms 631, allowing the two clamping arms 631 to open and close. In this way, the first rotating shaft 620 can be moved out of the locking interface 350 through the sliding groove 360, and the cylindrical cylinder 300 can then detach from the first rotating shaft 620. Optionally, the fourth elastic element 632 can be a spring, sheet metal, or other elastic element.

[0061] It should be noted that, in order to facilitate the transmission of the cylindrical cylinder 300, the clamping arm 631 and the fourth elastic element 632 are both located inside the cylindrical cylinder 300. Optionally, a movable space can be provided on the side wall of the cylindrical cylinder 300 to accommodate the clamping arm 631 and the fourth elastic element 632.

[0062] To prevent the clamping plate 641 from deflecting and affecting the rotation of the cylindrical cylinder 300 in the event of failure of the third elastic element 642 or axial deformation of the third elastic element 642, in some optional embodiments, such as Figure 5 As shown, an auxiliary push-pull structure 800 is also provided between the clamping plate 641 and the first rotating shaft 620. The auxiliary push-pull structure 800 is used to drive the two sets of clamping plates 641 to move closer to each other when the cylindrical tube 300 rotates relative to the surrounding plate 610.

[0063] Specifically, the auxiliary push-pull structure 800 includes meshing gears 810, a torsion spring 820, and parallel rows of teeth 830. A first rotating shaft 620 is sleeved on one of the gears 810, and the torsion spring 820 is located between the gear 810 and the first rotating shaft 620. When the first rotating shaft 620 rotates relative to the surrounding plate 610, the torsion spring 820 provides a resisting force to prevent the first rotating shaft 620 from rotating. Both rows of teeth 830 are slidably mounted on the surrounding plate 610, and are respectively located on both sides of the two parallel gears 810. The two rows of teeth 830 are meshed with the two gears 810 respectively, and are also respectively connected to two clamping plates 641.

[0064] In this embodiment, when the cylindrical cylinder 300 is dragged by the first mounting part and changes from a vertical state to an inclined state, the cylindrical cylinder 300 drives the first rotating shaft 620 to rotate on the surrounding plate 610. The gear 810 connected to the first rotating shaft 620 also rotates, thereby driving the other gear 810 to rotate synchronously. In this way, the two gears 810 can respectively drive the two gear racks 830 to slide on the surrounding plate 610, thereby driving the two clamping plates 641 to move, so that the two clamping plates 641 move away from each other. When the lifting device 200 is pulled out from the first receiving cavity 310, under the action of gravity... Under the combined action of the first and third elastic elements 642, the clamping plates 641 move closer to each other, while the gear 810 connected to the first rotating shaft 620 rotates in the opposite direction, thereby driving the other gear 810 to rotate synchronously. In this way, the two gears 810 can drive the two rows of teeth 830 to slide on the surrounding plate 610, so that the two clamping plates 641 move closer to each other until the cylindrical cylinder 300 changes from an inclined state to a vertical state. Moreover, during the movement of the clamping plates 641, the sliding of the rows of teeth 830 along a fixed path can play a certain limiting role, preventing the clamping plates 641 from deflecting.

[0065] In some alternative embodiments, such as Figure 1 , Figure 2As shown, the bottom of the transport trough 400 is provided with a clearance groove 440. The pushing mechanism 500 includes a pushing head 510, a telescopic mechanism 520, and a lifting mechanism 530. The telescopic mechanism 520 is tractively connected to the pushing head 510. When the telescopic mechanism 520 is in the extended state, it drives the pushing head 510 to move horizontally along the extension direction of the clearance groove 440. The lifting mechanism 530 is connected to the telescopic mechanism 520. When the lifting mechanism 530 is in the working state, it drives the telescopic mechanism 520 to approach the transport trough 400 until the pushing head 510 passes through the clearance groove 440, and a portion of the pushing head 510 extends into the transport trough 400. Thus, when the telescopic mechanism 520 drives the pushing head 510 to move, the pushing head 510 can push the cylindrical cylinder 300 inside the transport trough 400. When the pusher head 510 is pushed to the discharge end 420, the lifting mechanism 530 drives the telescopic mechanism 520 away from the transport trough 400 until the pusher head 510 is moved out of the clearance groove 440. Then the telescopic mechanism 520 drives the pusher head 510 to move to the vicinity of the feed end 410. Finally, the lifting mechanism 530 drives the telescopic mechanism 520 to approach the transport trough 400 until the pusher head 510 is inserted into the clearance groove 440 and part of the pusher head 510 extends into the transport trough 400. In this way, the telescopic mechanism 520 continues to push the pusher head 510 to move and continues to push the cylindrical cylinder 300 in the transport trough 400 to move.

[0066] In this embodiment, the lifting mechanism 530, the clearance groove 440, and the telescopic mechanism 520 work together to prevent the cylindrical cylinder 300, which is later placed in the transport groove 400, from blocking the pusher head 510 from moving back to the feed end 410. It should be noted that the telescopic mechanism 520 and the lifting mechanism 530 are existing technologies, and their specific structures will not be described in detail here. For example, the telescopic mechanism 520 is an electric pusher cylinder, and the lifting mechanism 530 is a linear motor.

[0067] In some alternative embodiments, such as Figure 9 As shown, the transport line 100 includes a track 110, a circulating drag chain 120, and a swing damping mechanism 130.

[0068] Specifically, the circulating cable chain 120 is mounted on the track 110, and the swing damping mechanism 130 is mounted on the circulating cable chain 120. The swing damping mechanism 130 is used to mount the lifting device 200, so that the swing damping mechanism 130 moves together with the circulating cable chain 120.

[0069] The swing damping mechanism 130 includes a first mounting bracket 131, a second rotating shaft 132, a second mounting bracket 133, a first friction plate 134, a second friction plate 135, and an anti-detachment hook 136. The first mounting bracket 131 is fixed to the circulating cable chain 120. The second rotating shaft 132 is rotatably mounted on the first mounting bracket 131, and the second mounting bracket 133 is sleeved on the second rotating shaft 132, so that the second mounting bracket 133 can rotate relative to the first mounting bracket 131. The first friction plate 134... The lower end is rotatably mounted on the second rotating shaft 132. The upper end of the first friction plate 134 is fixed on the first hanging seat 131. The upper end of the second friction plate 135 is sleeved on the second rotating shaft 132, so that the second friction plate 135 can rotate together with the second rotating shaft 132. The second friction plate 135 and the first friction plate 134 are in close contact. The lower end of the second friction plate 135 is fixed on the second hanging seat 133. The anti-detachment hook 136 is fixed on the second hanging seat 133.

[0070] In this embodiment, the interaction between the second friction plate 135 and the first friction plate 134 increases the resistance of the second hanger 133 when rotating relative to the first hanger 131. This causes the lifting device 200, attached to the anti-detachment hook 136, to sway significantly after being pulled out of the first receiving cavity 310, preventing collisions with other equipment or personnel in the work area. Furthermore, the lifting device 200 attached to the anti-detachment hook 136 can quickly straighten under gravity, facilitating the subsequent mounting of the workpiece on the lifting device 200.

[0071] To achieve automated material feeding, reduce manpower requirements, and improve operational efficiency, in some optional embodiments, such as Figure 10 , Figure 11 As shown, the automatic painting line hanger automatic loading device also includes an automatic feeding mechanism 900, which includes a material trough 910, a slide bar 920, a push rod 930, a second drive mechanism 940, and a robotic arm 950.

[0072] The material trough 910 is provided with a discharge channel 911, which has an inclined section 9111 and a straight section 9112. The straight section 911 has a clamping groove 9113. A slide rod 920 is provided on the material trough 910. The slide rod 920 matches the extension path of the inclined section 9111 and the straight section 9112. When the cylindrical cylinder 300 is inserted into the inclined section 9111 of the material trough 910, the second hook 220 is hooked onto the slide rod 920. This ensures that when the cylindrical cylinder 300 moves sequentially from the inclined section 9111 to the straight section 9112 into the clamping groove 9113, the hook face of the second hook 220 on the cylindrical cylinder 300 always faces upward. The push rod 930 is equipped with a push head 931, which has a limiting groove 9311 that matches the height of the second hook 220. When the cylindrical cylinder 300 slides into the clamping groove 9113, the second hook 220 with its hook face facing upward is limited in the limiting groove 9311. Then, the second drive mechanism 940 pushes the push rod 930 to move back and forth along the clamping groove 9113, completing the transfer operation of one cylindrical cylinder 300. Since the second hook 220 is limited in the limiting groove 9311, the hook face of the second hook 220 always faces upward when the push rod 930 pushes the cylindrical cylinder 300 to move in the clamping groove 9113. Finally, the robotic arm 950 changes the cylindrical cylinder 300 from a horizontal state to a vertical state and places it at the feed end 410. By repeating the above operation, multiple cylindrical cylinders 300 can be loaded in the transport trough 400.
