Description

Technical Field

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

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

[0003] In the past, traditional air spring processing equipment relied mainly on manual operation to complete most of the processes. For example, the handling of products was entirely done manually by employees, who also had to apply lubricant themselves. Throughout the production line, material movement depended on manual labor or simple conveyor systems. Due to this operating method, a production line often required a large number of employees to coordinate and cooperate in order to maintain a basic production schedule.

[0004] However, traditional equipment has many drawbacks. On the one hand, the numerous and labor-intensive operations required by employees can easily lead to fatigue due to repetitive tasks. On the other hand, the lack of flexibility in employee operation results in significant inconsistencies in the rolled products, making it difficult to guarantee product quality stability. Moreover, the long production lines and low material handling efficiency not only increase production costs but also severely impact overall production efficiency. Summary of the Invention

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

[0006] The automatic feeding, pressing, and rewinding system for air springs provided in this application adopts the following technical solution:

[0007] An automatic feeding, pressing, and rewinding system using an air spring includes:

[0008] A frame, wherein an installation station for installing air spring products is provided within the frame;

[0009] The upper mold located above the installation station is used to place the cover plate that is assembled with the top of the bladder;

[0010] The cover plate transfer mechanism is used to transfer the cover plate to the upper mold.

[0011] The moving mechanism is used to deliver the bladder with a base at the bottom into the installation station;

[0012] The lifting mechanism located below the installation station is used to push the bladder with a base at the bottom upwards to adjust the bladder to the set installation height;

[0013] The lower mold is used to position the bladder in 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 surrounds the outer periphery of the top of the bladder.

[0014] An oil spraying mechanism is used to spray lubricating oil into the mold groove to wet the top of the bladder;

[0015] A pressing mechanism is used to drive the upper mold downward to press the cover plate against the toe opening at the top of the bladder;

[0016] An airflow control component for controlling the inflation or deflation of the bladder: when the cover is rolled and pressed against the toe opening at the top of the bladder, the airflow control component is activated to inflate the inside of the bladder, and the lifting mechanism pushes the base at the bottom of the bladder upward so that the base is rolled tightly inside the bladder. When the base is pushed into place, the airflow control component releases the gas inside the bladder so that the bladder gradually covers the outer periphery of the base.

[0017] By adopting the above technical solution, the installation of air spring products is automated. A cover plate transfer mechanism automatically transfers the cover plate to the upper mold, while a moving mechanism automatically delivers the bladder with its base into the installation station. An oil spraying mechanism automatically sprays lubricating oil into the mold groove, reducing wear between the cover plate and the top of the bladder during installation. A pressing mechanism automatically presses the cover plate onto the toe of the bladder, improving installation accuracy. Furthermore, an airflow control component automatically controls the bladder inflation. During inflation, the bladder evenly wraps around the base until it reaches the rewind height. Exhausting the air then gradually tightens the base inside the bladder. This method improves product quality, reduces worker workload, increases production efficiency, and ensures product consistency by minimizing the randomness of manual operations. The rational layout of these mechanisms around the installation station within the frame optimizes the production line layout and reduces floor space requirements.

[0018] Preferably, it also includes a straightening mechanism, which is used to squeeze the outside of the bladder towards the base during the process of the airflow control component releasing the gas inside the bladder until the bladder is clamped to the base.

[0019] By adopting the above technical solution, during the process of the airflow control component releasing the gas inside the bladder, the straightening mechanism can squeeze the outside of the bladder towards the base, thereby accelerating the gas discharge and simultaneously straightening the base to prevent tilting and ensure the positional accuracy between the base and the bladder.

[0020] Preferably, the moving mechanism includes a horizontal slide rail extending toward the installation station, a slide block slidably connected to the interior of the horizontal slide rail, a translation drive for driving the slide block to slide, and a tray slidably connected to the horizontal slide rail, the tray being used to support a bladder with a base; the surface of the slide block is provided with a protrusion, and the bottom of the tray is provided with a recessed hole that engages with the protrusion;

[0021] When the moving mechanism sends the bladder with the base into the installation position, the translation drive causes the slide to slide toward the installation position. The tray moves synchronously with the slide under the action of the protrusion and the concave hole. When the tray is in place at the lifting mechanism, the lifting mechanism lifts the tray and the bladder with the base together by pushing upward. The protrusion and the concave hole separate, and the translation drive causes the slide to move out of the installation position.

[0022] After the air spring product installation is completed, the moving drive component drives the slide into the installation position until the protrusion aligns with the recess. The lifting mechanism lowers the tray and the air spring product already installed on the tray until the protrusion and recess are fully engaged. Then, the translation drive component drives the slide to move away from the installation position. The tray moves synchronously with the slide under the action of the protrusion and recess, so that the installed air spring product is removed from the installation position.

[0023] By adopting the above technical solution, the moving mechanism can automatically move the bladder with a base into and out of the installation station through the coordinated operation of components such as horizontal slide rails, slide blocks, translation drive components, and trays. This automated conveying method avoids the tediousness of manual handling and effectively reduces the labor intensity of employees. During the conveying process, the interlocking of the protrusions and concave holes ensures the stability of the synchronous movement of the tray and slide blocks, ensuring that the bladder is accurately delivered to the lifting mechanism, reducing interference with the lifting mechanism, and improving the smoothness of the process transition. When the lifting mechanism is working, the slide block can be moved out in time to avoid interference, making the entire installation process more compact and efficient, and improving production efficiency.

[0024] Preferably, it also includes a removal mechanism for removing the installed air spring product from the tray.

[0025] By adopting the above technical solution, the added removal mechanism can automatically remove the installed air spring products from the tray, further reducing manual operation and improving the automation and efficiency of the entire production process.

[0026] Preferably, the lower mold includes two mold units symmetrically distributed on both sides of the installation station, and each of the two mold units has a half-groove on its top. Lateral drive components are provided on both sides of the installation station to drive the two mold units closer to or further apart. When the lifting mechanism pushes the bladder with the base to the installation height, the lateral drive components drive the two mold units closer to each other and assemble them into the lower mold around the bladder. The half-grooves on the top of the two mold units are joined to form an annular mold groove.

[0027] By adopting the above technical solution, the two symmetrically distributed mold units can move closer or further apart under the drive of the lateral drive component, and can be easily assembled into a mold on the outer periphery of the bladder. The half-groove at the top of the mold is assembled to form a ring-shaped mold groove, which can accurately position the bladder in the installation position, ensuring the accuracy and stability of the bladder positioning, and facilitating the smooth installation of subsequent air spring products.

[0028] Preferably, the straightening mechanism includes two straightening cylinders symmetrically distributed at the installation position and arranged opposite each other. The mold unit has a through groove on its side for the straightening cylinders to pass through. When the airflow control component releases the gas inside the bladder, the two straightening cylinders enter the lower mold through the through groove of the adjacent mold unit and squeeze the outside of the bladder until the bladder is clamped to the base.

[0029] By adopting the above technical solution, during the process of the airflow control component releasing the gas inside the bladder, the two straightening cylinders can enter the lower mold through the through slots of the adjacent mold units, respectively, to squeeze the outside of the bladder and clamp the bladder to the base. This makes the assembly of the base and the bladder more compact and stable during the installation of the air spring product, thereby improving the assembly quality and consistency of the product.

[0030] Preferably, a locking component is provided at the upper mold to secure the cover plate, and the cover plate is removed from the installation station after being placed at the upper mold by the cover plate transfer mechanism.

[0031] By adopting the above technical solution, the automatic feeding, pressing, and rewinding system for air springs can secure the cover plate with locking components, allowing the cover plate transfer mechanism to smoothly remove it from the installation station after placing the cover plate. This avoids affecting subsequent operations due to an unstable cover plate, ensuring the orderly progress of air spring product installation and thus improving the stability and efficiency of product installation.

[0032] Preferably, it also includes a cover plate conveying device for conveying multiple cover plates and a processing device for processing the surface of the cover plates. The cover plate transfer mechanism transfers the cover plates from the cover plate conveying device to the processing device for processing, and then places the processed cover plates at the upper mold.

[0033] By adopting the above technical solution, multiple cover plates can be transported using the cover plate conveying device to meet the needs of mass production; the processing device can process the surface of the cover plates to make them meet the usage requirements; the cover plate transfer mechanism transfers the cover plates from the conveying device to the processing device for processing and then places them on the upper mold, realizing the automated conveying and processing of cover plates, reducing manual operation, reducing the labor intensity of employees, improving production efficiency, and ensuring product consistency.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The system can automatically place the cover plate, automatically spray lubricating oil, automatically inflate and deflate the bladder, and automatically pick up the product, reducing the workload of employees and improving their work efficiency;

[0036] 2. By utilizing the coordinated operation of various mechanisms to complete the installation of air springs, the production line layout was optimized and the floor space required was reduced;

[0037] 3. The automated operation of the equipment avoids the arbitrariness of manual operation and ensures product consistency. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0046] This application discloses an automatic air spring feeding, pressing, and rewinding system, referring to... Figure 1 and Figure 2 ,include:

[0047] In this embodiment, the frame 1 is the supporting structure of the entire system. It is made of metal material and can be assembled by welding, bolting, etc. The overall structure is door-shaped. The frame 1 is equipped with an installation station 11 for air spring product installation.

[0048] The upper mold 3 is positioned above the installation station 11 and is used to hold the cover plate that will be assembled to the top of the bladder 10. The upper mold 3 is made of high-strength mold steel, which is hard, wear-resistant, and can withstand the enormous pressure during the clamping 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, ensuring accurate positioning of the cover plate during clamping. A locking component is embedded in the bottom of the upper mold 3. The locking component can be an electromagnet to attract and fix the metal cover plate. Alternatively, the locking component can be an elastic gripper. The elastic gripper clamps the cover plate through elastic deformation, ensuring stable positioning of the cover plate on the upper mold 3. The locking component ensures the stability of the cover plate at the upper mold 3, preventing displacement during clamping and improving product quality.

[0049] In this embodiment, the cover plate conveying device 2 can be a conveyor belt, which can continuously and stably transport multiple cover plates to provide the cover plates required for the installation of air spring products in this system. Alternatively, it can be a rotary conveyor, which transports the cover plates sequentially to designated positions through rotation.

[0050] In this embodiment, the processing device can be a laser marking machine, used to engrave markings on the surface of the cover plate. Alternatively, it can be a grinding machine or other equipment to grind the surface of the cover plate, improving its surface quality.

[0051] In this embodiment, the cover plate transfer mechanism employs a multi-axis robotic arm, specifically comprising a robotic arm and an adsorption device. The robotic arm can be a 5-axis robot, possessing flexible movement capabilities, enabling it to move and rotate in multiple directions. The adsorption device can be an electromagnet or a vacuum suction cup. When using an electromagnet, magnetic force is generated by energizing the cover plate, and the magnetic force disappears when the power is turned off, facilitating the placement of the cover plate. If a vacuum suction cup is used, negative pressure is created by evacuating air to adsorb the cover plate. The cover plate transfer mechanism transfers the cover plate from the cover plate conveying device 2 to the processing device for laser engraving, then places the processed cover plate on the upper mold 3, and finally, the cover plate transfer mechanism withdraws from the installation station 11. In this process, the cover plate transfer mechanism organically connects these steps, achieving integrated operation of the cover plate from conveying, processing to installation, further improving the performance and efficiency of the entire air spring automatic feeding, pressing, and rewinding system, representing a comprehensive optimization and improvement of existing technologies.

[0052] Moving mechanism 5, refer to Figures 3 to 6In this embodiment, the conveying mechanism 5 is used to deliver the bladder 10 with a base 101 at its 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 interior of the horizontal slide rail 51, a translation drive 52 that drives 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 is generally a linear guide rail with a precision-machined surface to ensure smooth sliding of the slide block 53. The slide block 53 can be a metal block, sliding through the engagement of the slide block 53 with the straight groove inside the horizontal slide rail 51. The translation drive 52 can be a combination of a servo motor and a lead screw and nut pair. The servo motor drives the lead screw to rotate, and the lead screw moves the nut, thereby causing the slide block 53 to slide on the horizontal slide rail 51. Alternatively, a cylinder can be used as the translation drive 52 to directly push the slide block 53 to move. The tray 54 can be made of plastic or aluminum alloy, possessing a certain strength and light weight, making it convenient to support the bladder 10 with the base 101. The surface of the tray 54 is provided with positioning holes for engaging with the positioning protrusions on the bottom of the base 101. Additionally, a connecting slider 542 is fixed to the bottom of the tray 54, enabling sliding engagement with the horizontal slide rail 51, which facilitates stable sliding of the tray 54. Furthermore, a protrusion 531 is fixed to the surface of the slide block 53, using a circular or square positioning pin, located at the end of the slide block 53 near the installation position 11. A recessed hole 541 is provided through the bottom of the tray 54 to engage with the protrusion 531. The protrusion 531 engages with the recessed hole 541. When the conveying mechanism 5 delivers the bladder 10 with the base 101 into the installation station 11, the translation drive 52 drives the slide 53 to slide towards the installation station 11. The tray 54 moves synchronously with the slide 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 delivered into the installation station 11. This connection method is simple and reliable, easy to install and maintain, and can improve the working stability and accuracy of the conveying mechanism 5. It has a positive effect on improving the overall performance of the automatic air spring feeding, pressing and rewinding system, and is an effective improvement over the existing technology.

[0053] In this embodiment, the lifting mechanism 6 is located below the installation station 11. The lifting mechanism 6 employs a built-in lifting cylinder 61. The cylinder uses hydraulic oil to extend and retract the piston rod. The stroke and thrust of the cylinder are designed according to the installation requirements of the air spring, and it is equipped with an encoder or resistance gauge to provide feedback signals for precise height control. Alternatively, the lifting mechanism 6 can use an electric push rod, which uses a motor to drive a lead screw to move the push rod up and down, offering high control precision and low noise. Furthermore, a bearing plate 62 is fixed to the end of the piston rod of the built-in lifting cylinder 61. A slot 621 is formed on the upper surface of the bearing plate 62, extending along the length of the slide rail and directly opposite it. The slot 621 has openings at both ends and is adapted to the connecting slider 542 at the bottom of the tray 54. When the tray 54 is positioned at the lifting mechanism 6, the connecting slider 542 at the bottom of the tray 54 slides completely out from the horizontal slide rail 51 and into the slot 621 at the bearing plate 62 of the lifting mechanism 6. Then, the built-in lifting cylinder 61 of the lifting mechanism 6 lifts the tray 54 and the bladder 10 with the base 101 together by pushing upwards, so as to push the bladder 10 with the base 101 to the set installation height for subsequent installation steps. At this time, the protrusion 531 separates from the concave hole 541. The translation drive 52 drives the slide 53 to move out of the installation position 11.

[0054] The lower mold 4, in this embodiment, is used to position the bladder 10 within the installation station 11. The lower mold 4 is provided with a mold groove 42, which surrounds the outer periphery of the top of the bladder 10 when the lower mold 4 is in place at the installation station 11. Specifically, the lower mold 4 includes two mold units 41 symmetrically distributed on both sides of the installation station 11. Each mold unit 41 has a half-groove 421 on its top. The mold units 41 are generally made of mold steel, possessing high hardness and wear resistance. The shape and size of the half-groove 421 match the outer periphery of the top of the bladder 10. Furthermore, lateral drive assemblies 12 are provided on both sides of the installation station 11. The lateral drive assemblies 12 are specifically lateral cylinders, with each lateral cylinder corresponding to and fixed to one of the two mold units 41. By simultaneously extending or retracting the two lateral cylinders, the two mold units 41 can move closer or further apart. When the lifting mechanism 6 pushes the bladder 10 with the base 101 to the installation height, the lateral drive assembly 12 drives the two mold units 41 to approach each other and assemble into the lower mold 4 around the outer periphery of the bladder 10. The half-groove 421 on the top of the two mold units 41 are assembled to form an annular mold groove 42, which can accurately position the bladder 10.

[0055] In this embodiment, the oil spraying mechanism 7 is installed on the upper side of the installation station 11 and is used to spray lubricating oil into the mold groove 42 to wet the top of the bladder 10. Specifically, the oil spraying mechanism 7 includes an oil spraying ring 72 and a horizontally arranged transverse cylinder 71. The oil spraying ring 72 is installed at the end of the piston rod of the transverse cylinder 71, which pushes the oil spraying ring 72 to extend and retract. During oil spraying, the transverse cylinder 71 drives the oil spraying ring 72 to move above the mold groove 42 and around it. The oil spraying ring 72 has multiple spray holes, through which lubricating oil is evenly sprayed into the mold groove 42. The oil spraying mechanism 7 can also be a combination of a nozzle and an oil pump, where the oil pump delivers lubricating oil to the nozzle, which sprays oil directly into the mold groove 42.

[0056] In this embodiment, the clamping mechanism can be a hydraulic press, which generates strong pressure through a hydraulic system to drive the upper mold 3 downward, pressing the cover plate onto the toe opening at the top of the bladder 10. Alternatively, the clamping mechanism can be a pneumatic press, which uses compressed air to generate pressure to achieve the clamping action.

[0057] In this embodiment, the airflow control component is used to control the inflation or deflation of the bladder 10. The airflow control component may include an inlet valve, an exhaust valve, and an air pipe installed at the lower mold 4. When the cover plate is locked in the lower mold 4, the air pipes at the inlet valve and the exhaust valve are connected to the connecting holes at the cover plate. When the cover plate is rolled and pressed against the toe opening at the top of the bladder 10, the cover plate seals the top opening of the bladder 10, forming a relatively closed space. The air pipes at the inlet valve and the exhaust valve are connected to the bladder 10. The inlet valve controls the entry of gas into the bladder 10, the exhaust valve discharges gas from the bladder 10, and the air pipe connects the gas source and the bladder 10 to achieve gas delivery. The airflow control component can also use a solenoid valve to control the gas inflow and outflow, which is more precise and convenient. After the cover plate is rolled and pressed onto the toe opening at the top of the bladder 10, the airflow control component is activated, the air intake valve is opened, and the airflow enters the bladder 10 through the air tube to inflate the bladder 10. At this time, the lifting mechanism 6 pushes the base 101 at the bottom of the bladder 10 upward so that the base 101 is rolled tightly inside the bladder 10. When the base 101 is pushed into place, the airflow control component is activated, the air intake valve is closed, and the exhaust valve is opened to release the gas inside the bladder 10 from the air tube of the exhaust valve, so that the bladder 10 gradually deflates and covers the outer periphery of the base 101.

[0058] In this embodiment, the straightening mechanism includes two straightening cylinders 8 symmetrically distributed on both sides of the installation station 11 and arranged opposite each other. The mold unit 41 has a through-slot 43 on its side for the straightening cylinders 8 to pass through. During the process of the airflow control component releasing the gas inside the bladder 10, the two straightening cylinders 8 enter the lower mold 4 through the through-slots 43 of the adjacent mold units 41 and compress the outside of the bladder 10 until the bladder 10 is clamped to the base 101. The straightening cylinders 8 are generally pneumatically driven, featuring fast response and flexible operation. A rubber pad can be installed at the front end of its piston rod to provide sufficient pressure while preventing damage to the bladder 10 during compression. The straightening cylinders 8 can also be hydraulically driven; hydraulically driven cylinders have greater output force and are suitable for situations requiring higher clamping force. Adding a straightening mechanism during air spring installation further ensures a tight fit and accurate positioning between the bladder 10 and the base 101. When the airflow control component exhausts air, the straightening cylinder 8 squeezes the outside of the bladder 10, so that the bladder 10 better covers the outer periphery of the base 101, improving the quality and stability of the product. Compared with Example 1, the installation effect of the air spring is further optimized, which is a further improvement of the prior art.

[0059] In this embodiment, the removal mechanism 9 is used to remove the installed air spring products from the tray 54. The removal mechanism 9 can be an external gantry robot, which has a large working range and high movement accuracy. The gantry robot moves laterally and vertically to reach above the tray 54, and then uses an electromagnet or vacuum suction cup to pick up the installed air spring products and place them on the packaging line. The removal mechanism 9 can also be an articulated robot, which is more flexible and can adapt to different working scenarios and operational requirements. Adding the removal mechanism 9 allows the air spring products to be removed from the tray 54 promptly after installation, achieving continuity and automation in the production process. It avoids the tediousness and inefficiency of manual material handling, further improving production efficiency and optimizing the entire system's workflow, representing a significant improvement over existing air spring processing equipment.

[0060] This system automates the air spring installation process through the coordinated operation of its various mechanisms. Compared to traditional manual methods, it reduces employee movements and labor intensity, avoids the arbitrariness of manual operation, and thus ensures product consistency. Simultaneously, the orderly operation of each mechanism according to a pre-set program improves production efficiency, optimizes production line layout, and reduces floor space, significantly improving and contributing to existing air spring processing technology.

[0061] The workflow of this system is as follows: The manual places the metal cover plate on the positioning aluminum plate of the conveying device, and its electric rollers sequentially transport the metal cover plate to the position (the conveying pitch is tentatively set at 340mm). The two mold units 41 of the lower mold 4 are opened, and the manual places 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 and positions itself (controlled by an encoder or resistance ruler, and the height can be programmed). The two mold units 41 of the lower mold 4 close, and the pneumatic system sprays oil into the mold groove 42 of the lower mold 4. The servo-powered rollers of the conveying device transport the metal cover plate to the 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 mold 3 (with magnetic attraction). The five-axis robot returns to the origin, and the upper mold 3 moves downward to apply pressure and press, so that the cover plate is rolled into the toe opening of the bladder 10. Then, the air inlet valve is opened, and air is blown into the bladder 10 to inflate it. Then, the built-in lifting cylinder 61 of the lifting mechanism 6 moves upward, pushing the base 101 upward. Then, the exhaust valve releases air, causing the base 101 to gradually roll inward into the bladder 10. Air continues to be released, the upper mold depressurizes and moves upward, and 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 circumference of the base 101, completing the installation of the air spring product. Then, the lower mold 4 opens, the straightening cylinder 8 opens (the straightening cylinder 8 retracts away from the bladder 10), the built-in lifting cylinder 61 moves downward, the tray 54 moves out of the installation station 11, the external truss robot moves laterally in, the robot moves downward, picks up the installed air spring product, the robot moves upward, the external truss robot moves laterally out, the external truss robot moves downward to place the installed air spring product into the packaging carton, applies moderate pressure, demagnetizes, the robot moves upward to the origin, and manual packing (labeling and placing accessories) is performed.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
