Description

Technical Field

[0001] The present invention relates to the technical field of fully automatic assembly of pneumatic coils, and particularly to a fully automatic assembly device for pneumatic coils of air suspension. Background Art

[0002] The pneumatic coil of air suspension is an electromagnetic coil assembly responsible for controlling pneumatic actuators (such as air springs, solenoid valves) in the air suspension system. Its core function is to drive the opening and closing of valves and adjust the gas flow by the on-off or strength change of current signals, thereby realizing the self-adaptive adjustment of the stiffness and height of the vehicle suspension. It is the "electrical - pneumatic conversion core component" of the air suspension system, directly affecting the response speed and control accuracy of the suspension.

[0003] Fully automatic production of pneumatic coils means that through automated equipment and control systems, a series of production processes of pneumatic coils from raw materials to finished products can be completed with little or no manual intervention. Compared with traditional manual or semi-automatic production methods, fully automatic production can significantly improve production efficiency, reduce errors caused by manual operations, improve product quality and consistency, and reduce the scrap rate. At the same time, it can also reduce the dependence on manual labor, reduce labor intensity, and save production costs.

[0004] In the existing fully automatic production equipment for pneumatic coils, during winding, when the tension is uneven or the winding speed is different, it will cause the wires to be arranged chaotically on the bobbin, resulting in problems such as local stacking and jumping of wires, adjacent wires crossing, and partial areas being loose and overhead. At the same time, due to the different tightness of the tension, the wire diameter will be stretched, or the coil arrangement will be chaotic during winding. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art, and to propose a fully automatic assembly device for pneumatic coils of air suspension.

[0006] To achieve the above object, the present invention adopts the following technical scheme: A fully automatic assembly device for pneumatic coils of air suspension, including a base, a feeding hopper is fixedly connected to the left surface of the base, a discharging hopper is fixedly connected to the right surface of the base, a workbench is fixedly connected to the upper surface of the base, and further includes; A first motor, the first motor is arranged on one side of the inner layer track, an outer layer track is fixedly connected to the outer surface of the inner layer track, and a clamping member is fixedly connected to the inner surface of the outer layer track; A connecting frame, two groups of connecting frames are arranged on the first sliding frame, and one group of connecting frames is arranged on the second sliding frame. When working, the three connecting frames are arranged in a "pin" shape; A line feeder head is provided in the line barrel, an electric heating pipe is provided on the outer surface of the line feeder head, and one end of the line feeder head is connected to the line feeder pipe; A support block is installed on a side surface of the first telescopic rod, and a side surface of the support block is fixedly connected to the second telescopic rod.

[0007] Preferably, the outer surface of the first motor is wrapped by the discharge hopper, and the outer surface of the clamping member is provided with three groups of clamping arms.

[0008] Preferably, the workbench is provided with two groups on the upper surface of the base, which are symmetrical to each other, a threaded moving device is provided in the middle of the two groups of workbenches, and a second motor is provided inside the workbench.

[0009] Preferably, the lower end surface of the threaded moving device is fixedly connected to a wire barrel, and the outer surface of the wire barrel is provided with a wire conveying pipe, and the wire conveying pipe can be stretched and extended.

[0010] Preferably, one end of the second motor is fixedly connected to a rotating column, and a first telescopic rod is provided inside the rotating column.

[0011] Preferably, an electric slide is provided on the outer surface of the base, a first sliding frame is provided inside the left electric slide, and a second sliding frame is provided inside the right electric slide.

[0012] Preferably, one of the connecting frames arranged on the first sliding frame is at an upward angle of forty-five degrees, and the other is at a downward angle of forty-five degrees. A positioning pin is fixedly connected to the outer surface of the connecting frame at the downward angle of forty-five degrees. A ventilation groove is provided on the outer surface of the connecting frame, and an alloy roller is provided inside the connecting frame.

[0013] Preferably, the surface of the alloy roller is provided with a microwave texture, and a connecting shaft is provided inside the alloy roller.

[0014] Preferably, a material storage tank is provided inside the alloy roller, the material storage tank is filled with a phase change material, and the ventilation tank is provided on the back of the alloy roller.

[0015] Preferably, twelve groups of support blocks are provided on the first telescopic rod, and the second telescopic rod is arranged inside the first telescopic rod.

[0016] Compared with the existing technology, the advantages of the present invention are: 1. In this application, an inner crawler, an outer crawler, a workbench, a first telescopic rod and a support block are arranged. When the device is conveying materials such as skeletons that need to be wound with pneumatic coils, the materials will enter from the feed hopper, and then the inner crawler will drive the outer crawler for conveying. The outer crawler will drive the clamping part to move, and the clamping part will clamp the skeleton and convey it to the workbench. When it moves to the workbench, the first telescopic rod will extend from the rotating columns on both sides, and after extending into the gap in the middle of the skeleton, the second telescopic rod will lift the support block so that the support block is against the inside of the skeleton, thereby fixing the overall position of the skeleton.

[0017] 2. In this application, alloy rollers, connecting shafts, material storage tanks, connecting frames and ventilation tanks are arranged. When the wire is wound, the winding can be better carried out through the cooperation of the alloy rollers and the phase change material inside the material storage tank, ensuring that the winding tension forms a dynamic balance. At the same time, the higher the temperature of the wire when it comes out, the better the plasticity. The subsequent rapid cooling allows the wire to be quickly stabilized after winding, reducing the generation of stress. The setting of the connecting frame forms multiple wrap angles for the wire (the arc angle of the wire in contact with the roller surface). The friction force generated by the wrap angle forms a dynamic balance with the winding tension, and the tension is controlled and fine-tuned by continuous fine-tuning during winding.

[0018] To sum up, the present application can better clamp the skeleton that needs to be wound through the setting of the above-mentioned structure to prevent it from being offset. On the other hand, it can ensure that there will be no major problems with the tension during winding, and at the same time reduce the internal stress of the wire during winding, so as to improve the accuracy of the coil formed after the wire is wound.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1 to 11, An air suspension pneumatic coil full-automatic assembly device, including a base 1. A feeding hopper 2 is fixedly connected to the left surface of the base 1, and a discharging hopper 3 is fixedly connected to the right surface of the base 1. A workbench 9 is fixedly connected to the upper surface of the base 1. A first motor 4 is arranged inside the inner layer of the inner track 5 to drive the inner track 5. An outer track 6 is fixedly connected to the outer surface of the inner track 5. The inner track 5 will drive the outer track 6 to rotate and convey together. A clamping member 7 is fixedly connected to the inner surface of the outer track 6. The clamping member 7 is a prior art, and its specific structural design will not be elaborated here. There are two groups of connecting frames 22 arranged on the first sliding frame 20, and one group is arranged on the second sliding frame 21. When working, the three connecting frames 22 are arranged in a "pin" shape. A support block 18 is installed on one side surface of the first telescopic rod 16. The support block 18 is rotatably connected to the first telescopic rod 16. A second telescopic rod 17 is fixedly connected to one side surface of the support block 18. The connection between the support block 18 and the second telescopic rod 17 is rotatably connected. A wire feeding head 12 is arranged in a wire barrel 8. A heating tube 13 is arranged on the outer surface of the wire feeding head 12. The heating tube 13 is wrapped around the outer surface of the wire feeding head 12. One end of the wire feeding head 12 is connected to a wire conduit 11 in a penetrating manner.

[0023] The outer surface of the first motor 4 is wrapped by the discharging hopper 3. There are three groups of clamping arms arranged on the outer surface of the clamping member 7 for clamping the skeleton. There are two groups of workbenches 9 arranged on the upper surface of the base 1, which are symmetrically arranged. There are also two groups of second motors 14, and the rotational speeds of the two groups of motors are the same. A threaded moving device 10 is arranged in the middle of the two workbenches 9. The threaded moving device 10 drives the wire barrel 8 to move. The threaded moving device 10 is driven by a driving device inside the workbench 9. The driving device is a prior art, and its specific structural design will not be elaborated here.

[0024] The lower surface of the threaded moving device 10 is fixedly connected to the wire barrel 8. A wire conduit 11 is arranged on the outer surface of the wire barrel 8. The wire conduit 11 can be stretched and extended. During work, the wire conduit 11 extends and retracts back and forth. When it is necessary to feed wire to the left, the wire conduit 11 will extend, and when it is to the right, it will retract.

[0025] One end of the second motor 14 is fixedly connected to a rotating column 15. A first telescopic rod 16 is arranged inside the rotating column 15. An electric sliding table 19 is arranged on the outer surface of the base 1. A first sliding frame 20 is arranged inside the left electric sliding table 19, and a second sliding frame 21 is arranged inside the right electric sliding table 19. When the clamping member 7 opens, the first sliding frame 20 and the second sliding frame 21 move in the electric sliding table 19 to a position close to the skeleton material.

[0026] The connecting frames 22 provided on the first sliding frame 20 are respectively at an upward angle of forty-five degrees and a downward angle of forty-five degrees. Positioning pins are installed at the front and rear ends of the downward connecting frame 22. The positioning pins are prior art and will not be described in detail here. A ventilation groove 23 is provided on the outer surface of the connecting frame 22. An alloy roller 24 is provided inside the connecting frame 22. The alloy roller 24 will come into contact with the coil during operation.

[0027] The surface of the alloy roller 24 is provided with a microwave texture, and a connecting shaft 25 is provided inside the alloy roller 24. The connecting shaft 25 is rotatably connected to the connecting frame 22. A storage tank 26 is provided inside the alloy roller 24, and the internal filling of the storage tank 26 is a phase change material. The ventilation groove 23 is provided on the back of the alloy roller 24. When the alloy roller 24 rotates, heat is dissipated through the ventilation groove 23.

[0028] The first telescopic rod 16 is provided with twelve support blocks 18 , which are divided into three groups, with four blocks in each group. The second telescopic rod 17 is arranged inside the first telescopic rod 16 . The first telescopic rod 16 is lifted inside the second telescopic rod 17 to lift the support blocks 18 .

[0029] The specific working principle of the present invention is as follows: when the conveying skeleton and other materials need to be pneumatically coiled, the material will enter from the feed hopper 2, the first motor 4 will start, and drive the inner crawler 5 to move, and then the inner crawler 5 will drive the outer crawler 6 for conveying, and the outer crawler 6 will drive the clamping part 7 to move, and the clamping part 7 will clamp the skeleton and convey it to the workbench 9. When it moves to the workbench 9, the first telescopic rod 16 will extend from the rotating columns 15 on both sides. At this time, the clamping part 7 will open, and the first telescopic rod 16 will extend into the gap in the middle of the skeleton, and the second telescopic rod 17 will be lifted to lift the support block 18 so that the support block 18 is against the inside of the skeleton, thereby fixing the overall position of the skeleton.

[0030] After fixing the position of the skeleton, the second motors 14 on the left and right sides are started, driving the rotating column 15 to rotate, driving the first telescopic rod 16 to rotate, and causing the skeleton to rotate as well. At the same time, the internal wire transmission tube 11 of the wire barrel 8 performs wire transmission, and then outputs the wire from the wire transmission head 12 connected to each other by the wire transmission tube 11. During the coil transportation process, when passing through the wire transmission head 12, it will be heated by the electric heating tube 13, so that the stress of the wound wire when it is output is reduced. When the wire is heated, the internal stress of the wire can be partially eliminated under the combined action of tension and temperature (similar to the "annealing" effect), and it is not easy to change shape due to stress rebound after winding, thereby improving the dimensional stability of the coil.

[0031] When outputting the wire, the wire transmission head 12 will first contact the positioning pin on the connecting frame 22 to position one end of the coil winding. When the positioning is determined, as the skeleton rotates, the wire will be wound around the outside of the skeleton and will contact the alloy roller 24 during winding. The heated wire will have enhanced plasticity due to the increase in temperature and can fit tightly to the skeleton or the wire arrangement track during winding. The alloy roller 24 has high thermal conductivity and can quickly absorb the heat of the wire, so that the wire can be quickly cooled to near room temperature at the moment of winding, the plasticity is reduced and the rigidity is restored, thereby "locking" the current winding shape (such as bending angle, wire spacing) to avoid shape rebound due to subsequent tension changes or stress release. At the same time, uniform heat absorption and cooling can ensure the tension and shape consistency of each layer of wire, thereby improving the stability of the electrical performance of the coil, such as the inductance value and Q value, and is installed in the air suspension device.

[0032] The interior of the alloy roller 24 is filled with phase change material, which can better absorb heat from the wire, and cooperate with the ventilation groove 23 to better cool the surface of the alloy roller 24. The connecting frame 22 on the first sliding frame 20 and the second sliding frame 21 is in a herringbone shape. The core of the herringbone arrangement is to use three rollers to form multiple wrap angles for the wire (the arc angle of contact between the wire and the roller surface). The friction generated by the wrap angle forms a dynamic balance with the winding tension. During winding, the tension is controlled and fine-tuned through continuous fine-tuning. The superposition of multiple wrap angles makes the tension adjustment margin larger. At the same time, the surface of the alloy roller 24 is smooth and the friction coefficient is stable, which can not only ensure uniform friction between the wire and the roller (avoid sudden tension changes due to fluctuations in the friction coefficient), but also reduce wire wear; at the same time, the high rigidity of the alloy can ensure that the roller does not deform when subjected to force, and maintains a stable wrap angle.

[0033] When the winding is completed, the electric slide 19 moves the first sliding frame 20 and the second sliding frame 21 away from the frame, and the clamping member 7 clamps again, and then the clamping member 7 moves to the discharge hopper 3 for discharge.

[0034] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
