Description

Technical Field

[0001] This application relates to the field of air spring installation equipment, and particularly to an automatic air spring feeding, taking, crimping and rewinding system. Background Art

[0002] In the technical field of air spring processing equipment for automobiles (transport trucks), with the continuous development of the automotive industry, as one of the important components of automobiles, the market demand for air springs is increasing day by day. This has promoted the continuous progress of air spring processing technology, and urged processing enterprises to strive to improve production efficiency and product quality to meet the diverse needs of the market. Efficient and stable processing equipment helps to improve the production accuracy and reliability of air springs, and thus enhance the overall performance and ride comfort of automobiles, which is of great significance in the development of the automotive industry.

[0003] In the past, traditional air spring processing equipment mainly relied on manual operation to complete most of the processes. For example, the placement and positioning of products were all manually carried out by employees, and employees needed to apply lubricating oil by themselves. On the entire production line, the movement of materials also relied on manual labor or simple conveying devices. Due to this operation method, a production line often required the coordination of a large number of employees to maintain the basic production progress.

[0004] However, traditional equipment has many defects. On the one hand, employees have a large number of operating actions and extremely high labor intensity, and long-term repeated operations are prone to fatigue. On the other hand, the randomness of employees' operations is relatively large, which makes the consistency deviation of the rolled and pressed products obvious, and it is difficult to ensure the stability of product quality. Moreover, the production line is long and the material transfer efficiency is low, which not only increases the production cost, but also seriously affects the overall production efficiency. Summary of the Invention

[0005] In order to reduce the working intensity of workers, improve product consistency and improve product production efficiency, this application provides an automatic air spring feeding, taking, crimping and rewinding system.

[0006] The automatic air spring feeding, taking, crimping and rewinding system provided by this application adopts the following technical solutions: An automatic air spring feeding, taking, crimping and rewinding system, comprising: A frame, in which an installation station for air spring product installation operations is provided; An upper mold located above the installation station, for placing a cover plate assembled with the top of the airbag; A cover plate transfer mechanism for transferring the cover plate to the upper mold; A moving-in mechanism for feeding a bladder with a base at the bottom into the installation station; A lifting mechanism located below the installation station is used to push upward on the bladder with a base at the bottom to adjust the bladder to the set installation height. A lower mold is used to position the bladder within the installation station. The lower mold is provided with a mold groove. When the lower mold is in place at the installation station, the mold groove wraps around the outer periphery of the top of the bladder. An oil injection mechanism is used to inject lubricating oil into the mold groove to moisten the top of the bladder. A crimping mechanism is used to drive the upper mold downward to crimp the cover plate at the toe of the top of the bladder. An air flow control component for controlling the inflation or deflation of the bladder. After the cover plate is crimped at the toe of the top of the bladder, the air flow control component is activated to inflate the inside of the bladder. And the lifting mechanism pushes upward on the base at the bottom of the bladder so that the base tightly winds the bladder inside. When the base is pushed in place, the air flow control component releases the gas inside the bladder so that the bladder gradually wraps around the outer periphery of the base.

[0007] By adopting the above technical solutions, the automation of the installation operation of the air spring product is realized. The cover plate transfer mechanism automatically transfers the cover plate to the upper mold, the transfer mechanism automatically sends the bladder with a base at the bottom into the installation station, and the oil injection mechanism automatically injects lubricating oil into the mold groove, reducing the wear between the cover plate and the top of the bladder during installation; the crimping mechanism automatically crimps the cover plate at the toe of the top of the bladder, improving the installation accuracy of the cover plate; in addition, the air flow control component automatically controls the inflation of the bladder. In the state where the bladder is inflated, the bladder can evenly wrap around the outer periphery of the base until the base moves up to the rewinding height, and then by exhausting the air, the base gradually winds tightly inside the bladder. By adopting this method, the product quality of the air spring can be improved, the operation intensity of employees can be reduced, the production efficiency can be improved, and due to the reduction of the randomness of manual operation, the consistency of the product is guaranteed. At the same time, each mechanism is reasonably arranged around the installation station in the frame, which helps to optimize the production line layout and reduce the floor area.

[0008] Preferably, it further includes a straightening mechanism. During the process of the air flow control component releasing the gas inside the bladder, the straightening mechanism is used to extrude the outside of the bladder towards the base until the bladder and the base are clamped.

[0009] By adopting the above technical solutions, during the process of the air flow control component releasing the gas inside the bladder, the straightening mechanism can extrude the outside of the bladder towards the base, thereby accelerating the gas discharge, and at the same time playing a role in straightening the base to prevent tilting and ensuring the position accuracy between the base and the bladder.

[0010] Preferably, the moving-in mechanism includes a horizontal slide rail extending towards the installation station, a slide block slidably connected inside the horizontal slide rail, a translation driving member for driving the slide block to slide, and a tray slidably connected to the horizontal slide rail. The tray is used to carry the airbag with a base; a convex portion is provided on the surface of the slide block, and a concave hole for plugging and mating with the convex portion is provided at the bottom of the tray; When the moving-in mechanism sends the airbag with a base into the installation station, the translation driving member drives the slide block to slide towards the installation station. The tray moves synchronously with the slide block under the cooperation of the convex portion and the concave hole. When the tray is in place at the lifting mechanism, the lifting mechanism lifts the tray and the airbag with a base together by pushing upwards, and the convex portion is separated from the concave hole. The translation driving member drives the slide block out of the installation station; After the installation operation of the air spring product is completed, the driving member drives the slide block into the installation station until the convex portion is aligned with the concave hole. The lifting mechanism lowers the tray and the installed air spring product on the tray until the convex portion is plugged into the concave hole. Then, the translation driving member drives the slide block to move away from the installation station, and the tray moves synchronously with the slide block under the cooperation of the convex portion and the concave hole, so that the installed air spring product is moved out of the installation station.

[0011] By adopting the above technical solution, the moving-in mechanism can realize the automatic entry and exit of the airbag with a base into and out of the installation station with the coordinated operation of components such as the horizontal slide rail, the slide block, the translation driving member, and the tray. This automatic conveying method avoids the cumbersome manual handling, effectively reduces the labor intensity of employees; and during the conveying process, the plugging and mating of the convex portion and the concave hole ensure the stability of the synchronous movement of the tray and the slide block, ensuring that the airbag is accurately conveyed to the lifting mechanism, reducing the interference with the lifting mechanism, and improving the smoothness of the step connection; when the lifting mechanism is working, the slide block can be moved out in time to avoid interference, making the entire installation operation process more compact and efficient, and improving the production efficiency.

[0012] Preferably, it further includes a moving-out mechanism for moving out the installed air spring product from the tray.

[0013] By adopting the above technical solution, the added moving-out mechanism can automatically move out the installed air spring product from the tray, further reducing the manual operation link and improving the automation degree and efficiency of the entire production process.

[0014] Preferably, the lower die includes two die units symmetrically distributed on both sides of the installation station, and half grooves are provided at the tops of the two die units; lateral driving components are provided on both sides of the installation station for driving the two die units to approach or separate from each other; when the lifting mechanism pushes the airbag with the base to the installation height, the lateral driving components drive the two die units to approach each other and form the lower die by fitting together around the airbag, and the half grooves at the tops of the two die units are fitted together to form an annular die groove.

[0015] By adopting the above technical solution, the two symmetrically distributed die units can approach or separate from each other under the drive of the lateral driving components, and can be conveniently assembled into the lower die around the airbag. The half grooves at their tops are fitted together to form an annular die groove, which can accurately position the airbag in the installation station, ensuring the accuracy and stability of the airbag positioning and facilitating the subsequent smooth installation operation of the air spring product.

[0016] Preferably, the centering mechanism includes two centering cylinders symmetrically distributed in the installation station and oppositely arranged, and through grooves for the centering cylinders to pass through are provided on the sides of the die units; when the air flow control component discharges the gas inside the airbag, the two centering cylinders respectively enter the inside of the lower die through the through grooves of the adjacent die units and extrude the outside of the airbag until the airbag is clamped with the base.

[0017] By adopting the above technical solution, during the process of the air flow control component discharging the gas inside the airbag, the two centering cylinders can respectively enter the inside of the lower die through the through grooves of the adjacent die units, extrude the outside of the airbag and clamp the airbag with the base, making the assembly of the base and the airbag in the air spring product more compact and stable during the installation process, and improving the assembly quality and consistency of the product.

[0018] Preferably, a locking component is provided at the upper die for stabilizing the cover plate after the cover plate transfer mechanism places the cover plate at the upper die and withdraws from the installation station.

[0019] By adopting the above technical solution, the air spring automatic feeding, taking, buckling and rewinding system can use the locking component to stabilize the cover plate, enabling the cover plate transfer mechanism to withdraw from the installation station smoothly after placing the cover plate, avoiding affecting subsequent operations due to the unstable cover plate, ensuring the orderly progress of the air spring product installation operation, and thus improving the stability and efficiency of the product installation.

[0020] Preferably, it further includes a cover plate conveying device for conveying a plurality of cover plates and a processing device for processing the surface of the cover plates. The cover plate transfer mechanism transfers the cover plates at the cover plate conveying device to the processing device for processing, and then places the processed cover plates at the upper die.

[0030] The following is combined with Figures 1-6 This application is described in further detail.

[0031] The present application discloses an automatic feeding, taking, pressing and rewinding system for air springs. Figure 1 and Figure 2 ,include: Frame 1, in this embodiment, frame 1 is the supporting structure of the entire system, made of metal material, and can be assembled by welding, bolting, etc. The overall structure is door-shaped, and an installation station 11 for air spring product installation operations is provided in the frame 1.

[0032] The upper mold 3 is arranged above the installation station 11, and is used to place the cover plate assembled with the top of the bladder 10. Among them, the upper mold 3 is made of high-strength mold steel, which has high hardness and good wear resistance, and can withstand the huge pressure during the buckling process. Its shape and size are determined according to the design requirements of the air spring. The bottom surface of the upper mold 3 has specific grooves or protrusions for precise matching with the cover plate to ensure that the cover plate is accurately positioned during the buckling process. A locking assembly is embedded at the bottom of the upper mold 3, and the locking assembly can use an electromagnet to adsorb and fix the metal cover plate. The locking assembly can also be an elastic clamp. The elastic clamp clamps the cover plate through elastic deformation to ensure that the position of the cover plate on the upper mold 3 is stable. The locking assembly can ensure the stability of the cover plate at the upper mold 3, prevent the cover plate from shifting during the buckling process, and improve the quality of the product.

[0033] The cover conveying device 2, in this embodiment, can be a conveyor belt, which can continuously and stably convey multiple cover plates to provide the system with the cover plates required for the installation of air spring products. It can also be a turntable conveying device, which conveys the cover plates to the designated positions in sequence by rotating.

[0034] Processing device, in this embodiment, the processing device can be a laser marking machine for marking on the surface of the cover plate, or can be a grinder or other equipment for grinding the surface of the cover plate to improve the surface quality.

[0035] The cover plate transfer mechanism. In this embodiment, the cover plate transfer mechanism adopts a multi-axis manipulator, specifically including a robotic arm and a suction device. The robotic arm can be a 5-axis robot, which has flexible movement capabilities and can move and rotate in multiple directions. The suction device can be an electromagnet or a vacuum chuck. When using an electromagnet, a magnetic force is generated by energization to adsorb the cover plate, and the magnetic force disappears after power-off, facilitating the placement of the cover plate. If a vacuum chuck is used, a negative pressure is formed by pumping air to adsorb the cover plate. The cover plate transfer mechanism transfers the cover plate at the cover plate conveying device 2 to the processing device for laser engraving processing, then places the processed cover plate on the upper die 3, and finally the cover plate transfer mechanism withdraws from the installation station 11. In this link, the cover plate transfer mechanism organically connects these links, realizing the integrated operation of the cover plate from conveying, processing to installation, further improving the performance and efficiency of the entire air spring automatic feeding, taking, buckling and rewinding system, and is a comprehensive optimization and improvement of the existing technology.

[0036] The moving-in mechanism 5, referring to Figures 3 to 6, in this embodiment, the feeding mechanism 5 is used to feed the bladder 10 with a base 101 at the bottom into the installation station 11. Specifically, it includes a horizontal slide rail 51 extending towards the installation station 11, a slide block 53 slidably connected to the inside of the horizontal slide rail 51, a translation driving member 52 for driving the slide block 53 to slide, and a tray 54 slidably connected to the horizontal slide rail 51. The tray 54 is used to support the bladder 10 with the base 101. The horizontal slide rail 51 generally uses a linear guide rail, the surface of which is precisely machined to ensure the smooth sliding of the slide block 53 thereon. The slide block 53 can be a metal block, and the sliding is achieved through the cooperation between the slide block 53 and the straight groove inside the horizontal slide rail 51. The translation driving member 52 can be a combination of a servo motor and a lead screw nut pair. The servo motor drives the lead screw to rotate, and the lead screw drives the nut to move, so that the slide block 53 slides on the horizontal slide rail 51. A cylinder can also be used as the translation driving member 52 to directly push the slide block 53 to move. The tray 54 can be made of plastic or aluminum alloy, with a certain strength and a relatively light weight, which is convenient for carrying the bladder 10 with the base 101. The surface of the tray 54 is provided with positioning holes for cooperating with the positioning protrusions at the bottom of the base 101. In addition, a connecting slider 542 is fixed to the bottom of the tray 54, and the sliding fit with the horizontal slide rail 51 is achieved through the connecting slider 542, which is beneficial to the stable sliding of the tray 54. In addition, a protrusion 531 is fixed to the surface of the slide block 53. The protrusion 531 uses a round or square positioning pin and is located at one end of the slide block 53 close to the installation station 11. A concave hole 541 for inserting and cooperating with the protrusion 531 is penetrated through the bottom of the tray 54. Through the insertion and cooperation between the protrusion 531 and the concave hole 541. When the feeding mechanism 5 feeds the bladder 10 with the base 101 into the installation station 11, the translation driving member 52 drives the slide block 53 to slide towards the installation station 11, and the tray 54 moves synchronously with the slide block 53 under the cooperation of the protrusion 531 and the concave hole 541, so that the bladder 10 with the base 101 can be accurately fed into the installation station 11. This connection method is simple and reliable, convenient for installation and maintenance, can improve the working stability and accuracy of the feeding mechanism 5, and has a positive promoting effect on the overall performance of the air spring automatic feeding, buckling, retracting and coiling system, which is an effective improvement over the prior art.

[0037] Lifting mechanism 6. In this embodiment, the lifting mechanism 6 is located below the installation station 11. Among them, the lifting mechanism 6 adopts a built-in lifting oil cylinder 61. The oil cylinder realizes the telescopic movement of the piston rod through the inflow and outflow of hydraulic oil. The stroke and thrust of the oil cylinder are designed according to the installation requirements of the air spring, and an encoder or a resistance ruler is equipped to feedback signals to accurately control the height. The lifting mechanism 6 can also adopt an electric push rod, which realizes the up and down movement of the push rod through the drive of the motor by the screw rod, and has the characteristics of high control precision and low noise. In addition, a bearing plate 62 is fixed at the end of the piston rod of the built-in lifting oil cylinder 61. A clamping groove 621 is formed on the upper surface of the bearing plate 62. The clamping groove 621 extends along the length direction of the slide rail and is opposite to the slide rail. Both ends of the clamping groove 621 are open, and the clamping groove 621 is adapted to the connecting slider 542 at the bottom of the tray 54. When the tray 54 is in place at the lifting mechanism 6, the connecting slider 542 at the bottom of the tray 54 completely slides out of the horizontal slide rail 51 and slides into the clamping groove 621 at the bearing plate 62 of the lifting mechanism 6. Then, the built-in lifting oil cylinder 61 of the lifting mechanism 6 lifts the tray 54 and the air bag 10 with the base 101 upward together to push the air bag 10 with the base 101 to the set installation height for subsequent installation steps. At this time, the convex part 531 is separated from the concave hole 541. The translation driving member 52 drives the slide seat 53 out of the installation station 11.

[0038] Lower die 4. In this embodiment, the lower die 4 is used to position the air bag 10 in the installation station 11, and the lower die 4 is provided with a die groove 42. When the lower die 4 is in place at the installation station 11, the die groove 42 wraps around the outer periphery of the top of the air bag 10. Specifically, the lower die 4 includes two die units 41 symmetrically distributed on both sides of the installation station 11 respectively. Half grooves 421 are provided at the tops of the two die units 41. The die units 41 are generally made of die steel and have high hardness and wear resistance. The shape and size of the half groove 421 match the outer periphery of the top of the air bag 10. In addition, lateral driving components 12 are provided on both sides of the installation station 11. The lateral driving components 12 are specifically lateral cylinders. The two lateral cylinders correspond to the two die units 41 one by one and are fixed. Through the simultaneous extension or contraction of the two lateral cylinders, the two die units 41 are driven to approach or move away from each other. When the lifting mechanism 6 pushes the air bag 10 with the base 101 to the installation height, the lateral driving components 12 drive the two die units 41 to approach each other and form the lower die 4 on the outer periphery of the air bag 10. The half grooves 421 at the tops of the two die units 41 are joined together to form an annular die groove 42, which can accurately position the air bag 10.

[0039] The oil injection mechanism 7. In this embodiment, the oil injection mechanism 7 is installed at a position above the side of the installation station 11 and is used to spray lubricating oil into the mold groove 42 to soak the top of the leather bag 10. Specifically, the oil injection mechanism 7 includes an oil injection ring 72 and a horizontally arranged transverse moving cylinder 71. The oil injection ring 72 is installed at the end of the piston rod of the transverse moving cylinder 71. The transverse moving cylinder 71 is used to push the oil injection ring 72 to extend and retract. During oil injection, the transverse moving cylinder 71 drives the oil injection ring 72 to move above the mold groove 42 and surround the mold groove 42. There are a plurality of oil injection holes on the oil injection ring 72, and the lubricating oil is evenly sprayed into the mold groove 42 through these oil injection holes. The oil injection mechanism 7 can also adopt a combination of a nozzle and an oil pump. The oil pump transports the lubricating oil to the nozzle, and the nozzle directly sprays the lubricating oil into the mold groove 42.

[0040] The crimping mechanism. In this embodiment, the crimping mechanism can be a hydraulic press, which generates a powerful pressure through a hydraulic system to drive the upper mold 3 to move downward and crimp the cover plate at the toe of the top of the leather bag 10. The crimping mechanism can also be a pneumatic press, which uses compressed air to generate pressure to achieve the crimping action.

[0041] The air flow control component. In this embodiment, the air flow control component is used to control the inflation or deflation of the leather bag 10. The air flow control component can include an intake valve, an exhaust valve and an air pipe installed at the lower mold 4. When the cover plate is locked to the lower mold 4, the air pipes at the intake valve and the exhaust valve are both connected to the connection channels at the cover plate. When the cover plate is crimped at the toe of the top of the leather bag 10, the cover plate seals the top opening of the leather bag 10 and forms a relatively closed space. The air pipes at the intake valve and the exhaust valve are both connected to the leather bag 10. Among them, the intake valve is used to control the gas entering the leather bag 10, the exhaust valve is used to discharge the gas in the leather bag 10, and the air pipe connects the air source and the leather bag 10 to realize the transportation of gas. The air flow control component can also adopt a solenoid valve to control the entry and exit of gas, which is more accurate and convenient. After the cover plate is crimped at the toe of the top of the leather bag 10, start the air flow control component, open the intake valve, and make the air flow into the interior of the leather bag 10 through the air pipe to inflate and expand the interior of the leather bag 10. At this time, the lifting mechanism 6 pushes up the base 101 at the bottom of the leather bag 10 to make the base 101 tighten the interior of the leather bag 10. When the base 101 is pushed in place, start the air flow control component, close the intake valve, and open the exhaust valve to release the gas in the leather bag 10 from the air pipe of the exhaust valve, so that the leather bag 10 gradually deflates and thus wraps around the outer periphery of the base 101.

[0042] Alignment mechanism. In this embodiment, the alignment mechanism includes two alignment cylinders 8 symmetrically distributed on both sides of the installation station 11 and arranged oppositely. A through groove 43 through which the alignment cylinder 8 can pass is provided on the side of the mold unit 41. During the process of the air flow control component discharging the gas inside the bladder 10, the two alignment cylinders 8 respectively enter the lower mold 4 through the through grooves 43 of the adjacent mold units 41 and extrude the outside of the bladder 10 until the bladder 10 is clamped with the base 101. Among them, the alignment cylinder 8 generally uses pneumatic drive and has the characteristics of fast response speed and flexible movement. A rubber cushion block can be installed at the front end of its piston rod, which can provide sufficient pressure when extruding the bladder 10 and avoid damaging the bladder 10. The alignment cylinder 8 can also use hydraulic drive. The cylinder driven by hydraulic pressure has greater output force and is suitable for some situations with higher requirements for clamping force. During the installation process of the air spring, adding the alignment mechanism can further ensure the tight fit and positioning accuracy between the bladder 10 and the base 101. When the air flow control component exhausts, the alignment cylinder 8 extrudes the outside of the bladder 10, enabling the bladder 10 to better wrap around the outer circumference of the base 101, improving the quality and stability of the product. Compared with Embodiment 1, the installation effect of the air spring is further optimized, which is a further improvement to the prior art.

[0043] Removing mechanism 9. In this embodiment, the removing mechanism 9 is used to remove the installed air spring product from the tray 54. The removing mechanism 9 can be an external truss manipulator, which has a large working range and high movement accuracy. The truss manipulator moves horizontally and vertically to reach above the tray 54, and then uses an adsorption device such as an electromagnet or a vacuum chuck to pick up the installed air spring product and place it on the packaging line. The removing mechanism 9 can also be an articulated robot, which has higher flexibility and can adapt to different working scenarios and operation requirements. Adding the removing mechanism 9 enables the installed air spring product to be removed from the tray 54 in a timely manner after installation, realizing the continuity and automation of the production process. It avoids the cumbersome and inefficient manual material taking, further improves the production efficiency, optimizes the working process of the entire system, and is an important improvement to the existing air spring processing equipment.

[0044] Through the coordinated work of each mechanism, the system realizes the automation of the air spring installation operation. Compared with the traditional manual operation method, it reduces the operation actions and labor intensity of employees, avoids the randomness of manual operation, and thus ensures the consistency of products. At the same time, each mechanism operates orderly according to the preset program, improving the production efficiency, optimizing the production line layout, reducing the floor area, and making significant improvements and contributions to the existing air spring processing technology.

[0045] The working process sequence of this system is as follows: Manually place the metal cover plate on the positioning aluminum plate of the conveying device, and its electric rollers sequentially convey the metal cover plate to the designated position (the conveying pitch is tentatively set at 340 mm). The two die units 41 of the lower die 4 are opened. Manually place the bladder 10 with the base 101 installed on the tray 54 that has been moved out of the installation station 11. The tray 54 enters the installation station 11, and the built-in lifting cylinder 61 rises for positioning (controlled by an encoder or a resistance ruler, and the height can be programmed and set). The two die units 41 of the lower die 4 are closed. Pneumatically spray oil into the die groove 42 of the lower die 4. The servo power rollers of the conveying device convey the metal cover plate to the designated position (confirmed by a sensor). The five-axis robot of the cover plate transfer mechanism grabs the metal cover plate and places it into the upper die 3 (held firmly by a magnet). The five-axis robot returns to the origin. The upper die 3 descends to apply pressure and crimp, so that the cover plate is rolled into the toe opening of the bladder 10. Then, open the intake valve and blow air into the inside of the bladder 10 to make the bladder 10 inflate and expand. Then, the built-in lifting cylinder 61 of the lifting mechanism 6 ascends to push the base 101 upward. Then, the exhaust valve is actuated to release air, so that the base 101 gradually rolls into the bladder 10. Continue to exhaust air, and the upper die releases pressure and ascends. The straightening cylinder 8 closes (the straightening cylinder extends into the through groove 43 to squeeze the bladder 10 and the base 101), so that the bladder 10 wraps around the outer peripheral surface of the base 101, and the air spring product installation is completed. Then, the lower die 4 is opened, the straightening cylinder 8 is opened (the straightening cylinder 8 contracts in the direction away from the bladder 10), the built-in lifting cylinder 61 descends, the tray 54 moves out of the installation station 11, the external truss manipulator moves horizontally into place, the manipulator descends, sucks the installed air spring product, the manipulator ascends, the external truss manipulator moves horizontally out, the external truss manipulator descends to place the installed air spring product into the packaging carton, presses it moderately, demagnetizes, the manipulator ascends to the origin, and is manually packed (labels are pasted and accessories are placed).

[0046] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
