A kind of integrated surface treatment equipment of phoretic fluorocarbon aluminum profile

Abstract

This invention relates to the field of aluminum profile surface treatment technology, and provides an integrated surface treatment equipment for fluorocarbon coated aluminum profiles, including multiple treatment chambers, a ring-shaped suspension transmission assembly, and profile hangers. The ring-shaped suspension transmission assembly consists of a ring-shaped suspension track, a walking module, a connecting chassis, a control box, and a treatment seat, and also includes a control shaft, a drive mechanism, a lifting mechanism, a bounce control mechanism, and a friction limit mechanism. Through a pure mechanical linkage structure with single-axis synchronous drive of the control shaft, absolute timing synchronization is achieved when the hanger descends and locks, and when it rises and unlocks, thus offsetting the overturning torque generated during profile movement and treatment. This effectively suppresses profile shaking and resonance caused by bath scouring or hot air circulation, ensuring the relative position stability of the aluminum profile and electrode during the electrophoresis process. This meets the stringent requirements of electrophoresis and fluorocarbon spraying processes for the distance between the profile and electrode or spray gun, significantly improving the finished product quality and production efficiency of aluminum profile surface treatment.

Description

Technical Field

[0001] This invention belongs to the field of aluminum profile surface treatment technology, and particularly relates to an integrated surface treatment device for fluorocarbon coated aluminum profiles. Background Technology

[0002] Electrophoretic fluorocarbon composite surface treatment is a core surface treatment process for aluminum profiles used in high-end architectural decoration and industrial equipment. It combines the high uniformity and adhesion of electrophoretic film formation with the superior weather resistance and corrosion resistance of fluorocarbon coatings. The process includes aluminum profile pretreatment, electrophoretic film formation, primary curing, fluorocarbon electrostatic spraying, and secondary curing, ultimately forming a composite film layer on the aluminum profile surface that combines a ceramic-like texture with weather-resistant protective properties.

[0003] The existing integrated surface treatment equipment for fluorocarbon coated aluminum profiles consists of a processing mechanism, a conveyor system, a lifting electrophoretic spraying unit, and supporting auxiliary processing units. The processing mechanism is sequentially configured with multiple processing chambers, including a cleaning chamber, an electrophoretic coating chamber, a drying chamber, and a clear varnish spraying chamber. The conveyor system uses a closed-loop conveyor track and positioning frame to suspend and transport the aluminum profiles. The lifting electrophoretic spraying unit uses an independent motor-driven rack and pinion system to raise and lower the electrophoresis tank, working in conjunction with the spray guns, coating components, and hot air devices within each chamber to complete the entire processing flow. However, the existing equipment still has certain limitations in practical applications.

[0004] Firstly, in existing equipment, the constant position of the profile surface treatment is achieved by relying solely on the locking of the positioning frame itself. However, such stability is poor, causing the aluminum profile to continuously shake and resonate when it is flushed by the bath liquid, circulated by the hot air in the curing oven, or disturbed by the spraying airflow. On the one hand, this can cause the profiles to collide with each other or rub against the inner wall of the cavity, resulting in scratches and dents. On the other hand, it can cause significant fluctuations in the distance between the profile and the electrode during the electrophoresis process and between the profile and the spray gun during the spraying process, leading to fatal defects such as electrophoretic breakdown, missed coating, uneven film thickness, and sagging.

[0005] Secondly, some existing equipment has added a separate locking module to increase the contact area between the positioning frame and the track. However, the locking module and the lifting module are two completely independent drive systems, which rely entirely on the PLC control system and position sensor to match the timing of the action. In the surface treatment workshop, it is very easy for timing errors to occur, such as the descent before locking or the movement before unlocking. At best, this will cause the aluminum profile to collide and scratch the equipment cavity or the profile to be scrapped. At worst, it will cause major safety accidents such as the profile falling, the tank liquid leaking or the equipment being damaged.

[0006] Therefore, in view of the above situation, there is an urgent need to develop an integrated surface treatment equipment for fluorocarbon coated aluminum profiles to overcome the shortcomings in current practical applications. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated surface treatment equipment for fluorocarbon aluminum profiles to solve the problems mentioned in the background.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An integrated surface treatment equipment for fluorocarbon coated aluminum profiles includes multiple processing chambers arranged sequentially along the profile processing steps, an annular suspension conveyor assembly for conveying the aluminum profiles, and profile hangers for clamping the aluminum profiles. The annular suspension conveyor assembly consists of an annular suspension track and a traveling module. The annular suspension track is positioned directly above all the processing chambers. A connecting chassis is located at the bottom of the traveling module, and a control box is fixed to the bottom of the connecting chassis. The control box is hollow inside, and a processing seat is arranged parallel to it below. Multiple profile hangers are distributed vertically and equidistantly at the bottom of the processing seat. The equipment also includes:

[0010] A control shaft is vertically rotatable and installed inside the control box. One end of the control shaft is connected to a drive control mechanism and a lifting mechanism installed inside the control box. The other end of the control shaft has an axially threaded groove. One end of the lifting mechanism extends to the bottom of the control box and is connected to the top of the processing base.

[0011] A bouncing control mechanism is provided, comprising a vertical pushing component, a fixed base, a bouncing control component, a control rod, and a limiting post. The vertical pushing component is vertically slidably installed inside the control box. One end of the vertical pushing component is threadedly connected to a threaded groove on a control shaft. The other end of the vertical pushing component extends to the top of the control box and is connected to the power input end of the bouncing control component. The bouncing control component is installed on one side of the fixed base, which is vertically fixed to the top of the control box. A control rod is rotatably installed at the hinge of the bouncing control component. The limiting post is symmetrically fixed on the fixed base and intermittently limits the movement of the swing end of the bouncing control component.

[0012] A friction limiting mechanism is provided, with one end of the friction limiting mechanism fixed to the top of the fixed base, the extension end of the friction limiting mechanism located inside the annular suspension track and intermittently rubbing against its inner walls on both sides, and the power input end of the friction limiting mechanism being rotatably connected to one end of the control rod.

[0013] As a further technical solution of the present invention, the vertical pushing component includes a screw seat, a vertical slide column, a buffer slide groove, an arc-shaped push plate, a buffer spring, and a pushing column. The screw seat is threadedly connected to the threaded groove on the control shaft. One side of the screw seat is fixed to the bottom of the vertical slide column. The vertical slide column is vertically slidably installed on the top of the control box. A buffer slide groove is vertically opened in the middle of the vertical slide column. An arc-shaped push plate is slidably installed in the buffer slide groove. A buffer spring is installed between the top of the arc-shaped push plate and the bottom of the buffer slide groove. The top of the arc-shaped push plate abuts against the pushing column fixed on the power input end of the bounce control component.

[0014] As a further technical solution of the present invention, the bouncing control component includes a swing arm, a connecting rod, a slider, a slide block, and a bouncing spring. One end of the swing arm is rotatably mounted on a fixed base. The middle part of one side of the swing arm is fixedly connected to a push column. The other end of the swing arm is rotatably connected to one end of the connecting rod. The hinge joint between the swing arm and the connecting rod is rotatably connected to one end of a control rod. The other end of the connecting rod is rotatably connected to a slider that is horizontally slidably mounted in the slide block. The slide block is fixed on the fixed base. A bouncing spring is installed between one side of the slider and the slide block. The swing arm and the connecting rod maintain a preset obtuse angle and an acute angle. The initial preload of the buffer spring is less than the initial preload of the bouncing spring.

[0015] As a further technical solution of the present invention, the friction limiting mechanism includes a T-shaped mounting box, a vertical control block, friction limiting components, and a linkage spring. The T-shaped mounting box is fixed on the top of the fixed base. The interior of the T-shaped mounting box is hollow and divided into a horizontal telescopic end and a vertical control end. The vertical control block is vertically slidably mounted on the vertical control end of the T-shaped mounting box, and the bottom of the vertical control block is rotatably connected to the control rod. The vertical control block slides in cooperation with two friction limiting components symmetrically mounted on both sides of the horizontal telescopic end. A linkage spring is installed between the end faces of the two friction limiting components that are close to each other, and the end faces of the two friction limiting components that are far from each other extend to the outside of the T-shaped mounting box and intermittently rub against the side wall of the annular suspension track.

[0016] As a further technical solution of the present invention, the friction limiting assembly includes a transverse push block, a telescopic sleeve, a connecting seat, a friction limiting plate, and a telescopic spring. The transverse push blocks are symmetrically slidably installed on both sides of the transverse telescopic end. A linkage spring is installed between the inner end faces of the two transverse push blocks, and the inner end faces of the two transverse push blocks are respectively slidably engaged with the two end faces of the vertical control block. The end faces of the vertical control block and the transverse push blocks that are slidably engaged with each other are inclined end faces. The outer end faces of the two transverse push blocks are telescopically connected to the connecting seat through the telescopic sleeve, and a telescopic spring is installed between the outer end face of the transverse push block and the inner end face of the connecting seat. The outer end face of the connecting seat extends to the outside of the T-shaped mounting box and is fixedly connected to the friction limiting plate. The friction limiting plate intermittently rubs against the side wall of the annular suspension track.

[0017] As a further technical solution of the present invention, the lifting mechanism includes a driving component, a winding component, and a vertical telescopic component. The driving component is installed inside the control box. The winding component and the vertical telescopic component are equidistantly distributed circumferentially along the axis of the control shaft. One end of the winding component is connected to the driving component, and the other end of the winding component extends to the bottom of the control box and is fixedly connected to the processing seat. The two ends of the vertical telescopic component are respectively connected to the bottom of the control box and the top of the processing seat, and the vertical telescopic component is located outside the other end of the winding component.

[0018] As a further technical solution of the present invention, the drive assembly includes a main gear, a secondary gear and a drive shaft. The main gear is coaxially fixed on the outer wall of the control shaft. The secondary gears are equidistantly distributed along the axis of the control shaft and all mesh with the main gear. A drive shaft that is fixedly connected to one end of the winding assembly is coaxially fixed on the secondary gear.

[0019] As a further technical solution of the present invention, the winding assembly includes a winding reel, a wire rope and a directional pulley. The winding reel is coaxially fixed on the drive shaft. The wire rope is wound circumferentially on the winding reel. One end of the wire rope passes around the directional pulley fixed on the inner wall of the control box and is fixedly connected to the top of the processing seat. A vertical telescopic component is provided on the outer side of one end of the wire rope.

[0020] As a further technical solution of the present invention, the vertical telescopic component includes an inner telescopic cylinder, a middle telescopic cylinder and an outer telescopic cylinder. The inner telescopic cylinder is located outside the wire rope, and one end of the inner telescopic cylinder is fixed to the top of the processing seat. The outer telescopic cylinder is located outside the inner telescopic cylinder and is fixedly connected to the bottom of the control box. A plurality of middle telescopic cylinders are provided between the inner telescopic cylinder and the outer telescopic cylinder.

[0021] As a further technical solution of the present invention, the drive control mechanism includes a drive control motor, a drive control shaft and a transmission component. The drive control motor is fixed in the control box, and the drive control shaft is fixed on the output end of the drive control motor. The drive control shaft is connected to the control shaft through the transmission component.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] As the control shaft moves the processing seat and profile hanger downwards via the lifting mechanism, it can also activate the friction limiting mechanism via the bounce control mechanism. This allows the friction limiting mechanism to form a surface contact friction connection with the inner walls of the circular suspension track on both sides. Through this surface contact friction locking method, the traveling module and the circular suspension track form a rigid integrated connection. This, in turn, allows the suspended control box, lifting mechanism, processing seat, profile hanger, and aluminum profile to form an overall rigid and stable system, completely offsetting the overturning force generated during the profile's downward movement and processing. The torque effectively suppresses the shaking and resonance of the profile caused by the scouring of the bath liquid or the circulation of hot air, completely blocks the shaking transmission path, and eliminates collisions and scratches between profiles and between the profile and the inner wall of the cavity. At the same time, it ensures the stability of the relative position of the aluminum profile and the electrode during the crystal electrophoresis process, avoids defects such as electrophoretic breakdown or missed coating, meets the stringent requirements of the crystal electrophoresis and fluorocarbon spraying processes for the distance between the profile and the electrode or the spray gun, ensures the uniformity of the film thickness from the source, avoids defects such as electrophoretic breakdown, missed coating and sagging, and significantly improves the finished product quality and production efficiency of aluminum profile surface treatment.

[0024] Through a pure mechanical linkage structure driven by a single axis, the absolute timing synchronization of the fixture's descent and descent is achieved, which locks the fixture and unlocks it. No additional drive components or electronic timing control system are required. This completely avoids the equipment collisions, material scrapping, and safety accidents that are very likely to occur in the existing independent control mode of the subsystem, such as descent before locking or movement before unlocking. This greatly improves the reliability and safety of the equipment operation and ensures that the equipment is suitable for the harsh working conditions of surface treatment workshops with high humidity, corrosion, and dust.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figures 1 to 10 As shown, an integrated surface treatment device for electrophoretic fluorocarbon aluminum profiles, provided as an embodiment of the present invention, includes multiple processing chambers arranged sequentially along the profile processing steps, an annular suspension conveyor assembly for conveying aluminum profiles, and profile hangers 410 for clamping aluminum profiles. The annular suspension conveyor assembly consists of an annular suspension track 100 and a traveling module 200. The annular suspension track 100 is mounted directly above all the processing chambers. A connecting chassis 210 is provided at the bottom of the traveling module 200. A control box 300 is fixed at the bottom of the connecting chassis 210. The control box 300 is hollow inside, and a processing seat 400 is arranged parallel to it below. Multiple profile hangers 410 are distributed vertically and equidistantly at the bottom of the processing seat 400. The device also includes:

[0040] A control shaft 900 is vertically rotatable and installed inside the control box 300. One end of the control shaft 900 is connected to the drive control mechanism 800 and the lifting mechanism 500 installed inside the control box 300, respectively. The other end of the control shaft 900 is axially provided with a threaded groove 910. One end of the lifting mechanism 500 extends to the bottom of the control box 300 and is connected to the top of the processing seat 400.

[0041] A bouncing control mechanism 600 is provided, comprising a vertical pushing component 610, a fixed base 620, a bouncing control component 630, a control rod 640, and a limiting post 650. The vertical pushing component 610 is vertically slidably installed inside the control box 300. One end of the vertical pushing component 610 is threadedly connected to the threaded groove 910 on the control shaft 900, and the other end of the vertical pushing component 610 extends to the top of the control box 300 and is connected to the power input end of the bouncing control component 630. The bouncing control component 630 is installed on one side of the fixed base 620, which is vertically fixed to the top of the control box 300. The control rod 640 is rotatably installed at the hinge of the bouncing control component 630. The limiting post 650 is symmetrically fixed on the fixed base 620 and intermittently limits the movement of the swing end of the bouncing control component 630.

[0042] Friction limiting mechanism 700, one end of which is fixed to the top of fixed base 620, the extended end of which is located inside the annular suspension track 100 and intermittently rubs against its inner walls on both sides, and the power input end of friction limiting mechanism 700 is rotatably connected to one end of control rod 640.

[0043] The walking module 200, through the control box 300, lifting mechanism 500, processing seat 400 and profile hanger 410, can drive the clamped aluminum profiles to move sequentially along the layout trajectory of the annular suspension track 100 to the top of different processing chambers, realizing the integrated continuous processing of the entire process of aluminum profile pretreatment, crystal electrophoresis, curing, fluorocarbon spraying and secondary curing, without the need for secondary clamping and manual transfer throughout the process.

[0044] During the operation of the walking module 200, the bouncing control mechanism 600 drives the friction limiting mechanism 700 to a retracted state, so that the telescopic end of the friction limiting mechanism 700 is separated from the inner wall of the annular suspension track 100, eliminating contact wear and travel resistance, and ensuring smoothness during the conveying process. When the walking module 200 moves the profile hanger 410 to directly above the designated processing cavity, the drive control mechanism 800 drives the control shaft 900 to rotate. The control shaft 900 can not only drive the lifting mechanism 500 to work, but the lifting mechanism 500 can also drive the processing seat 400 and the profile hanger 410 to move vertically downwards simultaneously, accurately delivering the aluminum profile into the corresponding processing cavity. The corresponding surface treatment process is completed; it can also drive the vertical push component 610 to move upward through the threaded groove 910. The vertical push component 610 can drive the bounce control component 630 to quickly bounce away from the control box 300 by moving upward. The limit post 650 can control the bounce stroke of the bounce control component 630. The bounce control component 630 can drive the control rod 640 to swing upward through the directional bounce action. This allows the control rod 640 to drive the telescopic end of the friction limit mechanism 700 to expand laterally inside the annular suspension track 100, and finally form a surface contact friction connection with the inner walls on both sides of the annular suspension track 100.

[0045] This method not only achieves a rigid, integrated connection between the walking module 200 and the annular suspension track 100 through surface contact friction locking, but also creates a unified rigid and stable system for the suspended control box 300, lifting mechanism 500, processing seat 400, profile hanger 410, and aluminum profile. This completely counteracts the overturning moment generated during the profile's downward movement and processing, effectively suppressing profile swaying and resonance caused by the bath liquid scouring or hot air circulation, completely blocking the swaying transmission path, and preventing collisions and scratches between profiles or between the profile and the inner wall of the cavity. Simultaneously, it ensures the relative positional stability of the aluminum profile and electrode during the electrophoresis process, avoiding defects such as electrophoretic breakdown or incomplete coating, and meeting the requirements of the electrophoresis and fluorocarbon spraying processes. The stringent requirements for the distance between the material and the electrode or spray gun ensure the uniformity of the film thickness from the source, avoiding defects such as electrophoretic breakdown, incomplete coating, and sagging, and significantly improving the finished product quality and production efficiency of aluminum profile surface treatment. It can also achieve absolute time synchronization of the hanging fixture locking when it descends and unlocking when it rises through a pure mechanical linkage structure with single-axis synchronous drive. No additional drive components and electrical timing control system are required. It completely avoids the equipment collision, profile scrapping and safety accidents that are very likely to occur in the existing independent control mode of the subsystem, such as descending before locking or moving before unlocking. It greatly improves the reliability and safety of equipment operation and ensures that the equipment is suitable for the harsh working conditions of surface treatment workshops with high humidity, corrosion and dust.

[0046] like Figures 2 to 6 As shown, in a preferred embodiment of the present invention, the vertical pushing assembly 610 includes a screw seat 611, a vertical slide column 612, a buffer groove 613, an arc-shaped push plate 614, a buffer spring 615, and a pushing column 616. The screw seat 611 is threadedly connected to the threaded groove 910 on the control shaft 900. One side of the screw seat 611 is fixed to the bottom of the vertical slide column 612. The vertical slide column 612 is vertically slidably mounted on the top of the control box 300. A buffer groove 613 is vertically opened in the middle of the vertical slide column 612. An arc-shaped push plate 614 is slidably mounted in the buffer groove 613. A buffer spring 615 is installed between the top of the arc-shaped push plate 614 and the bottom of the buffer groove 613. The top of the arc-shaped push plate 614 abuts against the pushing column 616 fixed on the power input end of the bounce control assembly 630.

[0047] During the operation of the walking module 200, the screw seat 611 is threadedly connected to the threaded groove 910 at the lower part of the control shaft 900. The screw seat 611 drives the vertical sliding column 612 to move downward, causing the pushing column 616 to abut against the top inner wall of the buffer slide 613. The buffer spring 615, through its own elastic force, can drive the arc-shaped push plate 614 to always abut against the pushing column 616. The vertical sliding column 612 drives the pushing column 616 to move downward, causing the friction limiting mechanism 700 to be in a retracted state, so that its telescopic end is completely separated from the inner wall of the annular suspension track 100, with no contact wear and traveling resistance, ensuring smoothness during the conveying process; when the walking module 200 drives the profile hanging After the device 410 moves to the top of the designated processing cavity, the drive control mechanism 800 drives the control shaft 900 to rotate. The control shaft 900 can not only drive the lifting mechanism 500 to work, but also drive the processing seat 400 and the profile hanger 410 to move vertically downwards simultaneously, and accurately send the aluminum profile into the corresponding processing cavity to complete the corresponding surface treatment process; it can also drive the vertical slide column 612 to move upwards through the threaded groove 910. The vertical slide column 612 drives the push column 616 to move upwards through the arc-shaped push plate 614 of the buffer spring 615, so that the push column 616 can drive the bounce control component 630 to quickly bounce away from the control box 300.

[0048] When the bouncing control component 630 contacts the limiting post 650 and stops bouncing, the vertical sliding post 612 continues to move upward and cooperates with the arc-shaped push plate 614 and the pushing post 616 to compress the buffer spring 615, causing the arc-shaped push plate 614 to slide relative to the vertical sliding post 612, and the buffer spring 615 to be in a compressed state; while the bouncing control component 630, through the directional bouncing action, can drive the control rod 640 to swing upward, so that the control rod 640 can drive the telescopic end of the friction limiting mechanism 700 to expand laterally inside the annular suspension track 100, and finally form a surface contact friction connection with the inner walls on both sides of the annular suspension track 100, so that the walking module 200 and the annular suspension track 100 form a rigid integrated connection, thereby allowing The suspended control box 300, lifting mechanism 500, processing seat 400, profile hanger 410, and aluminum profile form an overall rigid and stable system. This system completely counteracts the overturning torque generated during the profile's downward movement and processing, effectively suppressing profile shaking and resonance caused by bath scouring or hot air circulation. It completely blocks the shaking transmission path, preventing collisions and scratches between profiles and between the profile and the inner wall of the cavity. At the same time, it ensures the relative position stability of the aluminum profile and electrode during the electrophoresis process, avoiding defects such as electrophoretic breakdown or missed coating. This meets the stringent requirements of electrophoresis and fluorocarbon spraying processes for the distance between the profile and electrode or spray gun, ensuring the uniformity of the film thickness from the source, avoiding defects such as electrophoretic breakdown, missed coating, and sagging, and significantly improving the finished product quality and production efficiency of aluminum profile surface treatment.

[0049] like Figures 2 to 6As shown, in a preferred embodiment of the present invention, the bouncing control assembly 630 includes a swing arm 631, a connecting rod 632, a slider 633, a slide block 634, and a bouncing spring 635. One end of the swing arm 631 is rotatably mounted on a fixed base 620. The middle part of one side of the swing arm 631 is fixedly connected to a push column 616. The other end of the swing arm 631 is rotatably connected to one end of the connecting rod 632. The hinge joint between the swing arm 631 and the connecting rod 632 is rotatably connected to one end of a control rod 640. The other end of the connecting rod 632 is rotatably connected to a slider 633 that is horizontally slidably mounted in the slide block 634. The slide block 634 is fixed on the fixed base 620. A bouncing spring 635 is installed between one side of the slider 633 and the slide block 634. The swing arm 631 and the connecting rod 632 always maintain a preset obtuse or acute angle.

[0050] During the operation of the walking module 200 and the downward movement of the vertical slide column 612 driving the push column 616, the push column 616 drives the swing arm 631 to rotate towards the control box 300. The swing arm 631 drives the control rod 640 downward through the connecting rod 632. The control rod 640 drives the friction limit mechanism 700 to work, putting it in a retracted state. When the threaded groove 910 drives the vertical slide column 612 upward, since the initial preload of the spring 635 is slightly greater than the initial preload of the buffer spring 615, the vertical slide column 612 can drive the push column 616 upward through the arc-shaped push plate 614 of the buffer spring 615 during the initial upward movement. At this time, the buffer spring 615 will first undergo slight deformation, so that there is a certain gap between the top of the buffer groove 613 and the push column 616. When the buffer spring 615 no longer deforms, it can drive the swing arm 631 away from the control box 300 through the arc-shaped push plate 614 and the push column 616. Rotating in the direction of 00, the swing arm 631, through the connecting rod 632, can not only drive the control rod 640 upward, but also drive the slider 633 to move towards the slide block 634. The slider 633 compresses the spring 635, completing the pre-compression and energy storage of the spring 635. When the swing arm 631 drives the connecting rod 632 to rotate to the collinear position, the spring 635 can release its own elastic force and drive the slider 633 to slide quickly in the opposite direction. The slider 633 drives the connecting rod 632 and the swing arm 631 to rotate quickly away from the control box 300, thereby driving the control rod 640 to move upward quickly, realizing the rapid jumping trigger of the jumping control component 630. This allows the control rod 640 to quickly drive the friction limit mechanism 700, greatly reducing the time difference between the locking action of the friction limit mechanism 700 and the downward movement of the profile hanger 410, completely eliminating the risk of locking lag, and significantly improving the trigger response sensitivity of the equipment.

[0051] When the swing arm 631 rotates rapidly until it contacts the upper limit post 650, the bouncing control component 630 stops bouncing. The vertical slide post 612 continues to move upward under the drive of the screw seat 611 and cooperates with the arc-shaped push plate 614 and the push post 616 to compress the buffer spring 615, causing the arc-shaped push plate 614 to slide relative to the vertical slide post 612, and the buffer spring 615 to be in a compressed state.

[0052] In a preferred embodiment, the initial preload of the buffer spring 615 is slightly less than the initial preload of the bouncing spring 635. In the initial stage of the vertical slide column 612 moving upward, the pre-compression resistance of the bouncing spring 635 is greater than the supporting elastic force of the buffer spring 615. The upward force of the vertical slide column 612 will preferentially compress the buffer spring 615, forming a preset empty stroke without locking action. During this process, the control shaft 900 synchronously drives the lifting mechanism 500 to drive the profile hanger 410 to complete a small pre-descent, so that the long aluminum profile is accurately aligned with the entrance of the processing cavity, completing the pre-alignment without shaking. After the buffer spring 615 is compressed to the preset stroke, its compression elastic force and the upward thrust of the vertical slide column 612 are superimposed, which can stably overcome the resistance of the bouncing spring 635, triggering the rotation of the swing arm 631 and the bouncing locking action. After locking is completed, the lifting mechanism 500 drives the profile to descend the full stroke into the cavity.

[0053] like Figures 2 to 7 As shown, in a preferred embodiment of the present invention, the friction limiting mechanism 700 includes a T-shaped mounting box 710, a vertical control block 720, a friction limiting component 730, and a linkage spring 740. The T-shaped mounting box 710 is fixed to the top of the fixed base 620. The T-shaped mounting box 710 is hollow inside and divided into a horizontal telescopic end and a vertical control end. The vertical control block 720 is vertically slidably mounted on the vertical control end of the T-shaped mounting box 710, and the bottom of the vertical control block 720 is rotatably connected to the control rod 640. The vertical control block 720 is slidably engaged with two friction limiting components 730 symmetrically mounted on both sides of the horizontal telescopic end. A linkage spring 740 is installed between the end faces of the two friction limiting components 730 that are close to each other. The end faces of the two friction limiting components 730 that are far from each other extend to the outside of the T-shaped mounting box 710 and intermittently rub against the side wall of the annular suspension track 100.

[0054] The friction limiting assembly 730 includes a transverse push block 731, a telescopic sleeve 732, a connecting seat 733, a friction limiting plate 734, and a telescopic spring 735. The transverse push blocks 731 are symmetrically slidably mounted on both sides of the transverse telescopic end. A linkage spring 740 is installed between the inner end faces of the two transverse push blocks 731, and the inner end faces of the two transverse push blocks 731 are respectively slidably engaged with the two end faces of the vertical control block 720. The vertical control block 720 and the transverse push blocks 731 are... The sliding contact end faces are all inclined end faces. The outer end faces of the two transverse push blocks 731 are telescopically connected to the connecting seat 733 through telescopic sleeves 732. A telescopic spring 735 is installed between the outer end face of the transverse push block 731 and the inner end face of the connecting seat 733. The outer end face of the connecting seat 733 extends to the outside of the T-shaped mounting box 710 and is fixedly connected to the friction limiting plate 734. The friction limiting plate 734 intermittently rubs against the side wall of the annular suspension track 100.

[0055] When the walking module 200 is moving normally, the control lever 640 drives the vertical control block 720 to slide downward along the longitudinal control end. The lifting force of the guide slope of the vertical control block 720 on the transverse push block 731 disappears. The two sets of transverse push blocks 731 approach each other under the contraction pull of the linkage spring 740, and drive the connecting seat 733 and the friction limit plate 734 to retract inward synchronously, so that the friction limit plate 734 is completely separated from the inner wall of the annular suspension track 100, leaving a walking interval, with no contact wear and no travel resistance.

[0056] When the control lever 640 swings upward rapidly, it drives the vertical control block 720 to slide upward rapidly along the longitudinal control end. The vertical control block 720, through the contact transmission between the guide inclined surface and the driven inclined surface, pushes the two transverse push blocks 731 to both sides and overcomes the tension of the linkage spring 740, causing the two transverse push blocks 731 to slide outward synchronously. The transverse push blocks 731, through the telescopic sleeve 732 and the connecting seat 733, push the friction limiting plate 734 outward until the wear-resistant friction layer of the friction limiting plate 734 forms a surface with the inner walls of both sides of the annular suspension track 100. Contact pressing is used to complete friction locking; during the locking process, if there is wear or dimensional deviation on the inner wall of the track, the telescopic spring 735 can adaptively compensate for the stroke through elastic deformation, ensuring that the friction limit plate 734 always keeps the entire plate surface in contact with the inner wall of the track, avoiding insufficient locking force or slippage caused by point contact or line contact, so that the walking module 200 and the ring suspension track 100 form a rigid integrated connection, thereby allowing the suspended control box 300, lifting mechanism 500, processing seat 400, profile hanger 410 and aluminum profile to form an overall rigid and stable system.

[0057] In a preferred embodiment, the outer dimensions of the connecting seat 733 are smaller than the inner diameter of the transverse section of the T-shaped mounting box 710, and the outer dimensions of the friction limiting plate 734 are larger than the outer diameter of the transverse section of the T-shaped mounting box 710. This allows the inner side of the friction limiting plate 734 to abut against the outer transverse end wall of the T-shaped mounting box 710 as the two transverse push blocks 731 approach each other, thereby limiting and controlling the transverse travel of the transverse push blocks 731 and completely avoiding the failure of inclined surface disengagement or mechanism jamming caused by excessive sliding of the transverse push blocks 731.

[0058] like Figure 2 , Figure 3 , Figures 8 to 10 As shown, in a preferred embodiment of the present invention, the lifting mechanism 500 includes a drive assembly 510, a winding assembly 520, and a vertical telescopic assembly 530. The drive assembly 510 is installed inside the control box 300. The winding assembly 520 and the vertical telescopic assembly 530 are equidistantly distributed circumferentially along the axis of the control shaft 900. One end of the winding assembly 520 is connected to the drive assembly 510, and the other end of the winding assembly 520 extends to the bottom of the control box 300 and is fixedly connected to the processing seat 400. Both ends of the vertical telescopic assembly 530 are connected to the bottom of the control box 300 and the top of the processing seat 400, respectively, and the vertical telescopic assembly 530 is located outside the other end of the winding assembly 520.

[0059] The drive assembly 510 includes a main gear 511, a secondary gear 512, and a drive shaft 513. The main gear 511 is coaxially fixed on the outer wall of the control shaft 900. The secondary gears 512 are equidistantly distributed along the axis of the control shaft 900 and all mesh with the main gears 511. The drive shaft 513, which is fixedly connected to one end of the winding assembly 520, is coaxially fixed on the secondary gears 512.

[0060] When the walking module 200 moves the profile hanger 410 to directly above the designated processing cavity, the drive and control mechanism 800 drives the control shaft 900 to rotate. The control shaft 900 can drive the main gear 511 to rotate, and the main gear 511 can drive multiple auxiliary gears 512 to rotate synchronously. The multiple auxiliary gears 512 drive multiple winding components 520 to work synchronously through the drive shaft 513. The multiple winding components 520, in cooperation with multiple vertical telescopic components 530, can drive the processing seat 400 to move stably and continuously downward. The processing seat 400 can drive the profile hanger 410 to move downward synchronously, so that the profile hanger 410 can accurately send the aluminum profile into the corresponding processing cavity to complete the corresponding surface treatment process, thereby realizing the integrated continuous processing of the entire process of aluminum profile pretreatment, crystal electrophoresis, curing, fluorocarbon spraying and secondary curing.

[0061] like Figure 2 , Figure 3 , Figures 8 to 10 As shown, in a preferred embodiment of the present invention, the winding assembly 520 includes a winding reel 521, a wire rope 522, and a directional pulley 523. The winding reel 521 is coaxially fixed on the drive shaft 513. The wire rope 522 is wound circumferentially on the winding reel 521. One end of the wire rope 522 passes around the directional pulley 523 fixed on the inner wall of the control box 300 and is fixedly connected to the top of the processing seat 400. A vertical telescopic assembly 530 is provided on the outer side of one end of the wire rope 522.

[0062] The vertical telescopic assembly 530 includes an inner telescopic cylinder 531, a middle telescopic cylinder 532, and an outer telescopic cylinder 533. The inner telescopic cylinder 531 is located outside the wire rope 522, and one end of the inner telescopic cylinder 531 is fixed to the top of the processing seat 400. The outer telescopic cylinder 533 is located outside the inner telescopic cylinder 531 and is fixedly connected to the bottom of the control box 300. A plurality of middle telescopic cylinders 532 are provided between the inner telescopic cylinder 531 and the outer telescopic cylinder 533.

[0063] When multiple drive shafts 513 rotate synchronously, they can drive multiple winding reels 521 to rotate synchronously, enabling the winding reels 521 to simultaneously release and wind up the wire rope 522. During the release or winding of the wire rope 522, it can cooperate with the vertical telescopic component 530 to complete the vertical stable movement of the treatment seat 400. This allows the treatment seat 400 to drive the profile hanger 410 to move vertically synchronously, enabling the profile hanger 410 to accurately feed the aluminum profile into the corresponding treatment cavity to complete the corresponding surface treatment process. This achieves integrated continuous processing of the entire process of aluminum profile pretreatment, electrophoresis, curing, fluorocarbon spraying, and secondary curing.

[0064] In a preferred embodiment, the inner telescopic cylinder 531, the middle telescopic cylinder 532, and the outer telescopic cylinder 533 are all provided with annular anti-detachment limiting bosses at both ends. The steel wire rope 522 runs along the axis of the inner telescopic cylinder 531, the middle telescopic cylinder 532, and the outer telescopic cylinder 533 throughout its entire length. The traction direction and the guiding direction are completely coaxial, eliminating the risk of radial force component and uneven wear. Combined with multiple sets of synchronous structures distributed circumferentially, the tilting, swaying, or twisting problems of the handling seat 400 during the lifting process are completely eliminated, ensuring that the aluminum profile is accurately inserted into the cavity and preventing scratches on the profile or damage to the equipment caused by collisions during cavity insertion.

[0065] like Figures 2 to 10 As shown, in a preferred embodiment of the present invention, the drive control mechanism 800 includes a drive control motor 810, a drive control shaft 820 and a transmission component 830. The drive control motor 810 is fixed inside the control box 300, and the drive control shaft 820 is fixed on the output end of the drive control motor 810. The drive control shaft 820 is connected to the control shaft 900 through the transmission component 830.

[0066] After the walking module 200 drives the profile hanger 410 to precisely stop above the designated processing cavity and complete the pre-positioning, the drive motor 810 starts and drives the control shaft 900 to rotate through the drive shaft 820 and the transmission component 830, so that the single control shaft 900 outputs two sources of power simultaneously. The control shaft 900 can not only drive the vertical push component 610 to move upward through the threaded groove 910, triggering the bounce control mechanism 600 to complete the bounce trigger, and simultaneously drive the friction limit mechanism 700 to form a surface contact friction lock with the annular suspension track 100, locking the position of the walking module 200; it can also drive the multiple winding components 520 of the lifting mechanism 500 to release the rope synchronously through the planetary transmission structure of the main gear 511 and the secondary gear 512 on the outer wall, and with the guidance of the vertical telescopic component 530, drive the profile hanger 410 to move down smoothly without swaying, and accurately send it into the rated position of the processing cavity, realizing absolute timing synchronization of locking first and then descending;

[0067] Once a single process is completed, the drive motor 810 starts in reverse, causing the control shaft 900 to rotate synchronously in the opposite direction. The control shaft 900 can not only drive the vertical push component 610 to move downward, triggering the bounce control mechanism 600 to reset, and drive the friction limit mechanism 700 to retract and unlock; it can also drive the winding component 520 to synchronously wind up the rope, and drive the profile hanger 410 to rise and reset smoothly, achieving absolute timing synchronization of rising first and then unlocking, preparing for the walking module 200 to move to the next process station.

[0068] In a preferred embodiment, the transmission component 830 is preferably a belt drive structure consisting of a synchronous belt and a synchronous pulley.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
