Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more particularly to an aluminum profile overhead conveyor system. Background Technology

[0002] Currently, the suspension of aluminum profiles in aluminum profile overhead conveyor systems within the industry is generally done manually. This involves operators manually moving the aluminum profiles to the suspension components, adjusting their posture one by one, and then securing them to the suspension structure. After the suspension operation is complete, the conveyor system is started for transport. While this manual suspension method requires no complex auxiliary equipment and has low initial investment costs, it presents several problems in practical application, the most prominent being the high labor intensity.

[0003] Aluminum profiles, especially large industrial profiles, have considerable weight and length. Operators must continuously bear the weight of these profiles during manual handling, adjustment, and suspension. Repeatedly performing this task can easily lead to muscle strain and significantly increase labor intensity compared to ordinary jobs. Furthermore, manual suspension is inefficient, requiring operators to suspend each profile individually, which is unsuitable for large-scale, automated aluminum profile production. This can create bottlenecks in the conveying process and impact overall production efficiency. In addition, it's difficult to maintain consistent operational standards during manual suspension, leading to issues such as misalignment and insecure fixing. This can cause the profiles to shake or fall during transport, resulting in scratches, deformation, and other damage, and may also pose safety hazards, threatening the safety of operators.

[0004] Therefore, an automatic suspension and conveying system for aluminum profiles is needed to solve the problems of high labor intensity and low efficiency of the existing manual suspension of aluminum profiles. Summary of the Invention

[0005] In view of this, the present invention provides an aluminum profile suspension conveying system, which can realize automatic alignment and automatic hanging of aluminum profiles and hooks, replacing the traditional manual feeding and hanging mode, greatly reducing manpower input, and improving the overall operation efficiency and automation of aluminum profile suspension processing.

[0006] To achieve the above objectives, the present invention provides the following technical solutions.

[0007] 1. Aluminum profile overhead conveyor system, including: The profile conveying line is equipped with a profile loading station for conveying aluminum profiles; The positioning and clamping mechanism is used to clamp multiple aluminum profiles conveyed to the profile loading station, and to complete the end alignment of the multiple aluminum profiles and the alignment of a single aluminum profile with a single hook. Hook positioning mechanism, used to lock the hook's posture and position; The profile suspension mechanism is located above the profile loading station. The positioning and clamping mechanism is assembled on the profile suspension mechanism and can be driven by the profile suspension mechanism to move synchronously with the hook. The profile suspension mechanism is used to drive the aluminum profile held by the positioning and clamping mechanism to be hung on the corresponding hook.

[0008] After the suspended aluminum profiles are conveyed to the profile loading station via the profile conveyor line, the positioning and clamping mechanism simultaneously clamps multiple aluminum profiles, completing the alignment and calibration of the profile ends and the alignment of each aluminum profile with a single hook. Simultaneously, the hook positioning mechanism locks the hook posture at the corresponding station, keeping the hook and the corresponding aluminum profile relatively stationary. Then, the profile suspension mechanism drives the positioning and clamping mechanism and the clamped aluminum profile to lift as a whole, and then drives the aluminum profile towards the locked hook until the hole at the end of the aluminum profile is hooked onto the hook, thus completing the mounting operation between the aluminum profile and the hook. Clearly, through the coordinated operation of the profile conveyor line, the positioning and clamping mechanism, the hook positioning mechanism, and the profile suspension mechanism, automatic alignment and mounting of aluminum profiles with hooks are achieved, replacing the traditional manual loading and hanging mode, significantly reducing manpower input, and improving the overall operational efficiency and automation level of aluminum profile hanging processing.

[0009] 2. Based on technical solution 1, the positioning and clamping mechanism includes: The profile gripper is provided in multiple sets, with each set of profile grippers corresponding to one aluminum profile. The propulsion cylinder is located on one side of the aluminum profile; The push plate is connected to the piston rod of the propulsion cylinder; Suction cups are used to adhere aluminum profiles. After the aluminum profiles are conveyed to the profile loading station, each set of profile grippers holds the corresponding aluminum profile and can adjust the front and back positions of the corresponding aluminum profiles so that each aluminum profile can be aligned with the corresponding hook; air is injected into the push cylinder, the piston rod of the push cylinder extends and drives the push plate to squeeze the end of the aluminum profile so that the ends of all the clamped aluminum profiles are kept flush; then, the suction cups adsorb the clamped aluminum profiles to ensure that the position of the clamped aluminum profiles remains relatively stationary.

[0010] 3. Based on technical solution 1, the hook positioning mechanism includes: The push-pull cylinder can move synchronously with the hook; Mounting bracket, connected to the piston rod of the push-pull cylinder; The hook fixing clips are provided in multiple sets and are installed on the mounting frame along the arrangement direction of the hooks. Each set of hook fixing clips corresponds to one hook and can clamp and position the corresponding hook. When the aluminum profile to be suspended is transported to the profile loading station, air is supplied to the push-pull cylinder. The piston rod of the push-pull cylinder extends and drives the hook fixing clamp to move closer to the hook side. The hook fixing clamp holds the corresponding hook to keep the corresponding aluminum profile stationary.

[0011] 4. Based on technical solution 3, the hook fixing clamp includes top pressure cylinders symmetrically arranged on both sides of the hook, and two Y-shaped clamping parts corresponding to the two top pressure cylinders. Each Y-shaped clamping part is connected to the piston rod of the corresponding top pressure cylinder, and the two Y-shaped clamping parts can be driven by the top pressure cylinder to achieve opening and closing movements.

[0012] 5. Based on technical solution 3, each group is provided with three hook fixing clips, which are arranged from top to bottom and correspond to the head end, hook body and tail end of the hook respectively; the hook fixing clip corresponding to the tail end of the hook is fixedly installed with the mounting bracket, and the hook fixing clip corresponding to the head end and hook body of the hook is floatingly installed with the mounting bracket.

[0013] 6. Based on technical solution 5, the hook fixing clips corresponding to the hook head and the hook body are both installed on the mounting frame by floating springs.

[0014] 7. Based on technical solution 1, it also includes multiple automatic hook-threading mechanisms, each corresponding to an aluminum profile. The automatic hook-threading mechanism is assembled on the profile suspension mechanism and can be driven by the profile suspension mechanism to move synchronously with the aluminum profile and the hook, in order to complete the docking of the aluminum profile and the hook end.

[0015] 8. Based on technical solution 7, the automatic hook-threading mechanism includes: Push cylinder; The hook is connected to the piston rod of the push cylinder; After the hook fixing clamp holds the hook, air is supplied to the push cylinder. The push cylinder pushes the hook inserter through the end hole of the aluminum profile and onto the hook part of the hook to complete the connection between the aluminum profile and the hook part of the hook.

[0016] 9. Based on technical solution 8, the profile suspension mechanism includes: Upper support plate; The lower support plate is located below the upper support plate; A longitudinal drive pair is configured on the upper surface of the upper support plate to drive the clamped aluminum profile to move along the profile conveying direction. A transverse drive pair, installed between the upper support plate and the lower support plate, is used to drive the clamped aluminum profile to move horizontally towards the hook side; The lifting cylinder is installed on the lower side of the lower support plate and connected to the positioning and clamping mechanism to lift the clamped aluminum profile. It also includes a compensation and adjustment mechanism to compensate for the motion accuracy error between the lateral drive pair and the lifting cylinder, so as to reduce the force on the hooker when the aluminum profile slides along the hooker.

[0017] 10. Based on technical solution 9, the lateral drive pair includes: A sliding joint is used to slidably connect the upper support plate and the lower support plate. The lead screw and nut assembly consists of a lead screw and a lead nut. The lead screw is mounted on the lower side of the upper support plate and can be driven to rotate. The lead nut and the lead screw are threaded together, and the side wall of the lead nut has a locking groove. Compensation and adjustment mechanisms include: The sliding sleeve is fixed to the upper surface of the lower support plate, and the nut is located inside the sliding sleeve and slides with it; At least one return spring is provided and installed between the sliding sleeve and the nut; The locking cylinder is fixed to the outside of the sliding sleeve, and its piston rod can be inserted into the locking groove to lock the nut and the sliding sleeve. As the aluminum profile begins to slide down the hook inserter, the piston rod of the locking cylinder retracts to release the lock between the nut and the sleeve. Under the elastic action of the return spring, the aluminum profile has a margin of movement relative to the hook inserter to prevent the aluminum profile from forcibly squeezing the hook inserter.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1 , Figure 2 and Figure 3This embodiment provides an aluminum profile suspension conveying system, mainly used for the automated hanging operation of aluminum profiles 7. It can automatically hang the aluminum profiles 7 onto hooks 10 to meet the subsequent hanging painting processing requirements. The suspension conveying system includes a support frame 1, a profile conveying line 2, a positioning and clamping mechanism 3, a hook positioning mechanism 4, and a profile hanging mechanism 5. The profile conveying line 2 is used to convey the aluminum profiles 7 to be hung. The profile conveying line 2 and the hook conveying line 6 are arranged parallel to each other, and their conveying speeds are consistent to ensure that the aluminum profiles 7 can move synchronously with the corresponding hooks 10. The profile conveying line 2 is equipped with a profile loading station 21. The support frame 1 is fixedly installed on one side of the profile conveying line 2 and located at the profile loading station 21. The profile hanging mechanism 5 is installed below the support frame 1 and directly opposite the profile loading station 21. The positioning and clamping mechanism 3 is mounted on the profile suspension mechanism 5 and can be driven by the profile suspension mechanism 5 to move synchronously with the hook 10. The positioning and clamping mechanism 3 can synchronously clamp multiple aluminum profiles 7 conveyed to the profile loading station 21 to complete the end alignment of the profiles and the precise alignment of a single aluminum profile 7 with a single hook 10. The hook positioning mechanism 4 is located between the profile conveying line 2 and the hook conveying line 6 to lock the posture and position of the hook 10, preventing the hook 10 from shifting or shaking during the hanging operation of the aluminum profile 7, and ensuring the hanging accuracy. The profile suspension mechanism 5 also serves as the execution drive unit for the hanging operation of the aluminum profile 7, driving the positioning and clamping mechanism 3 and the clamped aluminum profile 7 to lift as a whole, and hanging multiple aluminum profiles 7 onto the corresponding hooks 10.

[0031] During operation, after the suspended aluminum profile 7 is conveyed to the profile loading station 21 via the profile conveying line 2, the positioning and clamping mechanism 3 simultaneously clamps multiple aluminum profiles 7, and completes the alignment and calibration of the profile ends and the alignment of a single aluminum profile 7 with a single hook 10. At the same time, the hook positioning mechanism 4 locks the posture of the hook 10 at the corresponding station, so that the hook 10 and the corresponding aluminum profile 7 remain relatively stationary. Then, the profile suspension mechanism 5 drives the positioning and clamping mechanism 3 and the clamped aluminum profile 7 to be lifted as a whole, and then drives the aluminum profile 7 to move toward the locked hook 10 until the hole at the end of the aluminum profile 7 is hooked onto the hook 10, thus completing the hanging operation between the aluminum profile 7 and the hook 10.

[0032] This embodiment achieves automatic alignment and automatic hanging of aluminum profile 7 and hook 10 through the coordinated operation of profile conveying line 2, positioning clamping mechanism 3, hook positioning mechanism 4 and profile hanging mechanism 5, replacing the traditional manual feeding and hanging mode, greatly reducing manpower input, and improving the overall operation efficiency and automation level of aluminum profile 7 hanging processing.

[0033] See Figures 3 to 8In this embodiment, the profile suspension mechanism 5 serves as the execution drive unit for the automatic suspension operation of the aluminum profile 7. It mainly consists of an upper support plate 51, a lower support plate 52, a positioning plate 53, a guide column 54, a longitudinal drive pair 55, a transverse drive pair 56, and a lifting cylinder 57. The upper support plate 51, the lower support plate 52, and the positioning plate 53 are arranged sequentially from top to bottom below the support frame 1. The upper support plate 51 is connected to the support frame 1 through the longitudinal drive pair 55. The longitudinal drive pair 55 is used to drive the positioning clamping mechanism 3 and the clamped aluminum profile 7 to move along the profile conveying direction, ensuring that the clamped aluminum profile 7 can maintain the same forward speed as the hook 10, thus providing a foundation for subsequent precise installation. The upper support plate 51 and the lower support plate 52 are connected by a transverse drive pair 56. The transverse drive pair 56 is used to drive the positioning and clamping mechanism 3 and the clamped aluminum profile 7 to translate towards the hook 10, so that the aluminum profile 7 moves closer to the hook 10. It is worth noting that both the longitudinal drive pair 55 and the transverse drive pair 56 are composed of a lead screw and nut pair and a sliding pair, which have the advantages of precise transmission and smooth operation, and can effectively ensure motion accuracy. Figure 4 and Figure 5 As shown, multiple guide posts 54 are evenly distributed between the lower support plate 52 and the positioning clamping mechanism 3. One end of each guide post 54 is fixedly connected to the lower side of the lower support plate 52, and the other end passes through a pre-drilled guide hole (not shown in the figure) on the positioning plate 53, ultimately connecting to the positioning clamping mechanism 3. The guide posts 54 provide guidance for the movement of the positioning clamping mechanism 3, preventing positional shifts and swaying during movement, thus further improving the mounting accuracy. The cylinder body of the lifting cylinder 57 is fixedly installed between the lower support plate 52 and the positioning plate 53. Its piston rod passes through the positioning plate 53 and connects to the positioning clamping mechanism 3. It is mainly used to drive the positioning clamping mechanism 3 to move vertically up and down, realizing the lifting action of the aluminum profile 7.

[0034] When the aluminum profile 7 to be suspended is conveyed to the profile loading station 21 by the profile conveying line 2, the longitudinal drive pair 55 starts first. Through the linkage of the upper support plate 51, the lower support plate 52 and the positioning plate 53, the positioning clamping mechanism 3 moves synchronously, so that the movement speed of the positioning clamping mechanism 3 is consistent with the conveying speed of the aluminum profile 7, ensuring that the positioning clamping mechanism 3 can clamp the aluminum profile 7 smoothly and accurately. After the positioning and clamping mechanism 3 clamps the aluminum profile 7, the lifting cylinder 57 is activated, driving the positioning and clamping mechanism 3 and the clamped aluminum profile 7 to rise to a preset height, preparing for the suspension of the aluminum profile 7. Subsequently, the lateral drive pair 56 is activated, driving the positioning and clamping mechanism 3 to move horizontally towards the hook 10 through the lower support plate 52 and the positioning plate 53. At the same time, the lifting cylinder 57 slowly drives the positioning and clamping mechanism 3 to move downward. During this process, the aluminum profile 7 presents an oblique downward movement trajectory towards the hook end of the hook 10 until the hole at the end of the aluminum profile 7 is accurately fitted onto the corresponding hook 10, completing a single suspension action.

[0035] To more clearly illustrate the motion characteristics of the aluminum profile 7, this embodiment defines the degrees of freedom of motion for the aluminum profile 7 as follows: the conveying direction of the aluminum profile 7 is the X-axis, the length direction of the aluminum profile 7 itself is the Y-axis, and the vertical direction is the Z-axis. Specifically, the longitudinal drive pair can drive the aluminum profile 7 to move along the X-axis, ensuring that the aluminum profile 7 moves synchronously with the hook 10; the lateral drive pair can drive the aluminum profile 7 to move along the Y-axis, allowing the profile to approach the hook 10; and the lifting cylinder can drive the aluminum profile 7 to move up and down along the Z-axis, achieving lifting and lowering of the profile. Based on these three degrees of freedom of motion, the aluminum profile 7 can complete a precise downward oblique mounting action while moving synchronously with the hook 10, ensuring a stable and efficient suspension process.

[0036] See Figure 4 and Figure 5 To achieve precise positioning of the aluminum profile 7 and the hook 10, the positioning and clamping mechanism 3 in this embodiment mainly consists of a gripper support plate 31, profile grippers 32, a suction cup 33, a push cylinder 34, and a push plate 35. The gripper support plate 31 is located below the positioning plate 53, and its upper surface is fixedly connected to the lower end of the guide column 54 and the piston rod of the lifting cylinder 57. It can move up and down vertically under the drive of the lifting cylinder 57, and simultaneously move forward and backward and left and right in sync with the positioning plate 53. Multiple sets of profile grippers 32 are provided. These multiple sets of profile grippers 32 are installed side by side on the lower surface of the gripper support plate 31 along the conveying direction (X-axis direction) of the aluminum profile 7. Each set of profile grippers 32 corresponds to one aluminum profile 7 to be suspended. Each set contains two profile grippers 32, which are arranged side by side along the length direction (Y-axis direction) of the aluminum profile 7. The profile gripper 32 is used to clamp the corresponding aluminum profile 7 and fine-tune the front and rear positions of the aluminum profile 7 to ensure that each aluminum profile 7 can be precisely aligned with the corresponding hook 10. Combined with... Figure 5 Two suction cups 33 are provided, which are installed side by side on the lower surface of the gripper support plate 31 along the length direction (Y-axis direction) of the aluminum profile 7. They can fix the aluminum profile 7 to be suspended by suction force, improve the stability of the aluminum profile 7 during movement, and prevent the aluminum profile 7 from deviating or shaking. The cylinder body of the push cylinder 34 is fixedly installed on the positioning plate 53, and its piston rod end is fixedly connected to the push plate 35. It can drive the push plate 35 to reciprocate along the length direction (Y-axis direction) of the aluminum profile 7 to realize the end alignment operation of the aluminum profile 7.

[0037] Driven by the longitudinal drive pair 55, the positioning and clamping mechanism 3 aligns each set of profile clamping claws 32 with the corresponding aluminum profile 7. Each set of profile clamping claws 32 generates clamping force on its corresponding aluminum profile 7 and makes fine adjustments to its front and back positions, so that the aluminum profile 7 is aligned with the hook 10 one by one, completing the alignment of a single aluminum profile 7 with a single hook 10. Gas is introduced into the push cylinder 34, and the piston rod of the push cylinder 34 extends accordingly, driving the push plate 35 to move towards the aluminum profile 7. After the push plate 35 contacts all the clamped aluminum profiles 7, the pushing force continues to be applied, pushing all the aluminum profiles 7 to move synchronously towards the hook 10 to the preset position. At this time, the ends of all the clamped aluminum profiles 7 remain flush, and the holes at their ends are also on the same straight line, ensuring that the holes of each aluminum profile 7 can accurately correspond to the corresponding hook 10. It should be noted that the function of the profile gripper 32 is to position the aluminum profile 7 front and back, ensuring that each aluminum profile 7 is aligned with the corresponding hook 10. Its gripping force is only used to fix the aluminum profile 7 and does not restrict its movement along the Y-axis. Therefore, when the push plate 35 presses the end of the aluminum profile 7 and pushes it to move horizontally, the profile gripper 32 will not obstruct it. Once the end of the aluminum profile 7 is aligned, the suction cup 33 immediately activates and adheres to the aluminum profile 7. Subsequently, the lifting cylinder 57 drives the gripper support plate 31 to move upwards. Under the suction force of the suction cup 33, the aluminum profile 7 moves upwards smoothly and synchronously, avoiding problems such as detachment or displacement, and ensuring the smooth progress of the suspension process.

[0038] In this embodiment, each set of profile grippers 32 in the positioning and clamping mechanism 3 is correspondingly set with a single aluminum profile 7, allowing for fine-tuning of the front and rear positions of the aluminum profile 7 to ensure that each aluminum profile 7 can be precisely aligned with the corresponding hook 10, preparing for subsequent suspension operations. The positioning and clamping mechanism 3 can also perform end alignment operations on multiple aluminum profiles 7. By using the pusher cylinder 34 to drive the push plate 35 to squeeze the aluminum profiles 7, all the clamped aluminum profiles 7 have their ends flush and their end holes are on the same straight line, avoiding suspension failures caused by alignment deviations and improving suspension accuracy. Furthermore, the suction cup 33 can be used to prevent the aluminum profiles 7 from shifting, shaking, or falling off during lifting, ensuring a smooth and orderly operation.

[0039] See Figure 4 , Figure 6 and Figure 7The hook positioning mechanism 4 in this embodiment mainly consists of a push-pull cylinder 41, a mounting frame 42, and a hook fixing clamp 43. The upper support plate 51 adopts an L-shaped structure. The cylinder body of the push-pull cylinder 41 is fixedly installed on the vertical plate of the upper support plate 51, and its piston rod end is connected to the mounting frame 42, which can drive the mounting frame 42 to move laterally left and right. The mounting frame 42 has a row of mounting slots 421 evenly spaced along the X-axis. Each mounting slot 421 is equipped with a set of hook fixing clamps 43. Each set of hook fixing clamps 43 corresponds to a hook 10 and is used to lock the position of the corresponding hook 10. Each set of hook fixing clamps 43 is equipped with three gripper components, respectively gripping the head end, hook body, and tail end of the hook 10. The hook fixing clamps 43 use a multi-point limiting method to ensure that the hook 10 is gripped more firmly and stably.

[0040] After the aluminum profile 7 to be suspended is conveyed to the profile loading station 21, gas is introduced into the push-pull cylinder 41. The piston rod of the push-pull cylinder 41 extends and drives the mounting bracket 42 to move closer to the hook 10. Since the push-pull cylinder 41 is mounted on the upper support plate 51, the whole can move forward synchronously with the upper support plate 51. The mounting bracket 42 and the hook fixing clip 43 can move at the same speed as the hook 10, so that each set of hook fixing clips 43 is accurately aligned with the hook 10 to be fixed, effectively locking the suspension posture and relative position of the hook 10.

[0041] Among them, combined Figure 7 As shown in the structure, each hook fixing clamp 43 in this embodiment includes a top-pressure cylinder 431 symmetrically arranged on both sides of the hook 10, and two Y-shaped clamping members 432 corresponding one-to-one with the two top-pressure cylinders 431. Each Y-shaped clamping member 432 is connected to the piston rod of the corresponding top-pressure cylinder 431 and can be driven by the top-pressure cylinder 431 to achieve opening and closing movements. When the hook 10 enters the middle area of ​​the two Y-shaped clamping members 432, the top-pressure cylinder 431 is vented, its piston rod extends, and pushes the two Y-shaped clamping members 432 towards each other until the hook 10 is firmly clamped and limited. The clamping members adopt a Y-shaped structure, which can expand the clamping range, has stronger fault tolerance, and can adapt to the slight deformation generated during the manufacturing of the hook 10, avoiding clamping failure and unstable positioning due to local deformation of the hook 10, and ensuring that the hook 10 is reliably clamped and fixed.

[0042] Furthermore, in order to accommodate the deformation caused by the processing of hook 10 and improve clamping compatibility, combined with Figure 7As shown, this embodiment employs differentiated structural designs for the hook fixing clips 43 at different positions. Since the actual hanging position of the aluminum profile 7 is the hook end of the hook 10, ensuring accurate positioning and fixed position of this part is sufficient to meet the suspension accuracy requirements of the aluminum profile 7. Therefore, the hook fixing clip 43 corresponding to the tail end of the hook 10 adopts a fixed installation structure to ensure stable hook posture without deviation; while the hook fixing clips 43 corresponding to the head end and body of the hook 10 adopt a floating design. The floating structure adapts to the forming deviation and local deformation of the hook 10, avoiding problems such as jamming or positioning failure caused by rigid clamping. Specifically, the hook fixing clips 43 corresponding to the head end and body of the hook 10 are additionally equipped with two sets of floating springs 45. The cylinder body of the top pressure cylinder 431 is elastically connected to the mounting bracket 42 through the floating springs 45. The elasticity of the floating springs 45 achieves position compensation, which can adaptively offset the dimensional deviation and slight deformation of the hook 10, ensuring a close clamping fit.

[0043] Furthermore, to ensure that the hook 10 has room to swing during the clamping process, combined with Figure 4 , Figure 5 As shown in the structure, the hook positioning mechanism 4 in this embodiment also includes a lifting cylinder 44. The cylinder body of the lifting cylinder 44 is fixedly connected to the piston rod end of the push-pull cylinder 41, and the piston rod of the lifting cylinder 44 is fixedly connected to the mounting frame 42, so that the mounting frame 42 has two degrees of freedom of movement: lateral movement along the Y-axis and vertical movement along the Z-axis. During the processing and forming of the hook 10, the angle of the hook end is prone to be too large. Under the clamping force of the hook fixing clamp 43 corresponding to the hook end, the hook end of the hook 10 needs to swing moderately away from the aluminum profile 7 to achieve reliable clamping and accurately fix the hook posture. In this embodiment, through the coordinated action of the lifting cylinder 44 and the push-pull cylinder 41, combined with the clamping limit of the hook fixing clamp 43, the hook 10 can be driven to move obliquely upward towards the aluminum profile 7, thereby reserving sufficient space for the hook 10 to adjust its swing, ensuring that the hook 10 is firmly clamped, and that the hook end posture of all hooks 10 is consistent, meeting the alignment accuracy requirements when the profile is suspended.

[0044] See Figure 6 and Figure 7 To ensure that the aluminum profile 7 can be smoothly and stably hung onto the hook 10, this embodiment also includes an automatic hook-threading mechanism 8, which assists in accurately connecting the aluminum profile 7 to the tail end of the hook 10. The automatic hook-threading mechanism 8 mainly consists of a push cylinder 81 and a hook threader 82, wherein the hook threader 82 adopts a cylindrical structure; the cylinder body of the push cylinder 81 is fixedly installed on the vertical plate of the upper support plate 51, and its piston rod is connected to the hook threader 82, which can drive the hook threader 82 to make a linear feed motion toward the hook part of the hook 10.

[0045] After the hook fixing clamp 43 holds the hook 10, gas is introduced into the push cylinder 81, the piston rod extends outward, and pushes the cylindrical hook inserter 82 forward, so that the hook inserter 82 passes through the end hole of the aluminum profile 7 and is fitted onto the hook part of the hook 10. Then, the lateral drive pair 56 drives the aluminum profile 7 to move laterally to one side of the hook 10, while the lifting cylinder 57 controls the aluminum profile 7 to slowly descend; the end hole of the aluminum profile 7 slides smoothly along the guide of the hook inserter 82, and is accurately fitted into the hook part of the hook 10, finally completing the automatic suspension of the aluminum profile 7, avoiding problems such as alignment deviation and jamming, and ensuring a smooth and reliable hanging process.

[0046] Among them, combined Figure 7 and Figure 10 As shown, the tail end of the hook threader 82 in this embodiment is provided with a plurality of scrapers 821 along the circumferential direction, which are used to scrape off the paint attached to the hook part of the hook 10, so as to avoid too much paint attached to the surface of the hook part of the hook 10, which would prevent the hook threader 82 from being able to be fitted onto the hook part at its tail end, thus affecting the hanging operation of the aluminum profile 7 and the hook 10.

[0047] To prevent the aluminum profile 7 from exerting a hard pressure on the hook 82 and hook 10 during the sliding mounting process along the hook slinger 82, due to the cumulative errors such as assembly deviations and transmission clearances of the transverse drive pair 56, longitudinal drive pair 55, and lifting cylinder 57, which could cause the hook 82 and hook 10 to bend and deform; combined with Figure 6 , Figure 8 and Figure 9 As shown in the embodiment, this structure also includes two sets of compensation and adjustment mechanisms 9. One set of compensation and adjustment mechanisms 9 is assembled between the support frame 1 and the upper support plate 51 to compensate for the motion accuracy error of the longitudinal drive pair 55; the other set is arranged between the upper support plate 51 and the lower support plate 52 to compensate for the motion accuracy error of the lateral drive pair 56. Through the error compensation of the two sets of compensation and adjustment mechanisms 9, the rigid force on the hook 82 and hook 10 when the aluminum profile 7 slides along the hook 82 can be reduced, protecting the structure of the hook 82 and hook 10 and preventing deformation under stress.

[0048] Since both the longitudinal drive pair 55 and the transverse drive pair 56 are composed of a lead screw and nut pair and a sliding pair, the two sets of compensation and adjustment mechanisms 9 have the same structural form and the same assembly and connection method as the longitudinal drive pair 55 or the transverse drive pair 56. The following is a specific explanation using the transverse drive pair 56 and its corresponding compensation and adjustment mechanism 9 as an example: the upper support plate 51 and the lower support plate 52 achieve sliding engagement through a sliding pair; the lead screw 561 of the lead screw and nut pair is installed on the lower side of the upper support plate 51 and can be driven to rotate by a motor; the nut 562 engages with the lead screw 561 through threaded transmission. This compensation and adjustment mechanism 9 mainly consists of a sliding sleeve 91, a return spring 92, and a locking cylinder 93. The sliding sleeve 91 is fixed to the upper surface of the lower support plate 52, and the nut 562 is located inside the sliding sleeve 91 and slides with it, which can prevent the torque of the lead screw 561 from causing the nut 562 to rotate, thus affecting the transmission accuracy. The sliding sleeve 91 is formed by two symmetrically arranged U-shaped blocks 911. There are four return springs 92 in total, divided into two groups. Two return springs 92 in each group are arranged along the axis of the lead screw 561 on the front and rear sides of the lead nut 562, respectively, and sandwiched between the U-shaped blocks 911 and the lead nut 562. A locking groove 563 is provided on the side wall of the lead nut 562. The cylinder body of the locking cylinder 93 is fixed to the outside of the sliding sleeve 91, and its piston rod can be inserted into the locking groove 563 to lock the lead nut 562 and the sliding sleeve 91. The locking cylinder 93 contains a return spring for the automatic retraction of the piston rod.

[0049] Before the aluminum profile 7 slides along the hook 82 for mounting, the piston rod of the locking cylinder 93 extends and engages in the locking groove 563 of the nut 562, locking the nut 562 with the sliding sleeve 91. At this time, the motor torque is directly and rigidly transmitted to the lower support plate 52 via the lead screw nut pair and the sliding sleeve 91, ensuring the running accuracy and overall stability of the aluminum profile 7 during the alignment and transfer stages. When the aluminum profile 7 begins to slide down the hook 82, the piston rod of the locking cylinder 93 retracts, releasing the lock between the nut 562 and the sliding sleeve 91. The sliding sleeve 91 has a small amount of movement relative to the nut 562 in the Y-axis direction. At this time, the torque of the motor is transmitted to the sliding sleeve 91 through the lead screw nut pair and the return spring 92 in sequence, and then transmitted to the lower support plate 52 and the aluminum profile 7 by the sliding sleeve 91. Relying on the elasticity of the return spring 92, it can absorb the rigid stress and position deviation in the transmission process, allowing the aluminum profile 7 to slide smoothly into place along the hook 82, avoiding hard compression, which would cause the hook 82 and hook 10 to bend or deform due to force.

[0050] The following further explains the working process of the present invention to further demonstrate its working principle and advantages: When the aluminum profile 7 to be suspended is conveyed to the profile loading station 21 by the profile conveying line 2, the longitudinal drive pair 55 is activated first. Through the linkage of the upper support plate 51, the lower support plate 52 and the positioning plate 53, the positioning clamping mechanism 3 is driven to move synchronously, so that the movement speed of the positioning clamping mechanism 3 is consistent with the conveying speed of the aluminum profile 7, ensuring that the positioning clamping mechanism 3 can clamp the aluminum profile 7 smoothly and accurately. Driven by the longitudinal drive pair 55, the positioning clamping mechanism 3 aligns each set of profile clamping claws 32 with the corresponding aluminum profile 7. Each set of profile clamping claws 32 generates clamping force on its corresponding aluminum profile 7 and makes fine adjustments to its front and back positions, so that the aluminum profile 7 is aligned with the hook 10 one by one, completing the alignment of a single aluminum profile 7 with a single hook 10. Gas is introduced into the push cylinder 34, and the piston rod of the push cylinder 34 extends, driving the push plate 35 to move towards the aluminum profile 7. After the push plate 35 contacts all the clamped aluminum profiles 7, the pushing force continues to be applied, pushing all the aluminum profiles 7 to move synchronously towards the hook 10 to the preset position. At this time, the ends of all the clamped aluminum profiles 7 remain flush, and the holes at their ends are also on the same straight line, ensuring that the holes of each aluminum profile 7 can accurately correspond to the corresponding hook 10. When the ends of the aluminum profiles 7 are aligned, the suction cup 33 immediately starts and adsorbs the aluminum profiles 7. Then, the lifting cylinder 57 drives the gripper support plate 31 to move upward, driving the positioning clamping mechanism 3 and the clamped aluminum profiles 7 to rise to the preset height, preparing for the suspension of the aluminum profiles 7. Then, the lateral drive pair 56 starts, driving the positioning clamping mechanism 3 and the aluminum profiles 7 to move a certain distance towards the hook 10 through the lower support plate 52 and the positioning plate 53. At this time, the holes of the aluminum profiles 7 are aligned with the hook threader 82 of the automatic hook threading mechanism 8. Simultaneously, gas is introduced into the push-pull cylinder 41, causing its piston rod to extend and move the mounting bracket 42 closer to the hook 10. Once the hook 10 enters the middle area of ​​the two Y-shaped clamping members 432, the pressure cylinder 431 is vented, its piston rod extends, and pushes the two Y-shaped clamping members 432 towards each other until the hook 10 is securely clamped and limited. Gas is then introduced into the push cylinder 81, causing its piston rod to extend outward and push the hook threader 82 forward, allowing it to pass through the end hole of the aluminum profile 7 and be fitted onto the hook portion of the hook 10. Before the aluminum profile 7 begins to slide down along the hook threader 82, the piston rod of the locking cylinder retracts, releasing the lock between the nut 562 and the sliding sleeve 91. The sliding sleeve 91 has a slight allowance of movement in the Y-axis direction relative to the nut 562. The lateral drive unit 56 drives the aluminum profile 7 to move laterally to the side of the hook 10, while the lifting cylinder 57 controls the aluminum profile 7 to slowly descend; the end hole of the aluminum profile 7 slides smoothly along the guide of the hook inserter 82, accurately fitting into the hook of the hook 10, and finally completing the automatic suspension of the aluminum profile 7.
