Description

Technical Field

[0001] This invention belongs to the technical field of valve installation equipment, specifically referring to an automatic valve installation device. Background Technology

[0002] As a crucial functional component for tire inflation and deflation, the installation quality of the valve stem directly impacts tire sealing performance and driving safety. With the rapid development of the automotive industry, the demand for wheel hub valve assembly is increasing, leading to ever-higher requirements for assembly efficiency and precision. Traditional valve installation methods largely rely on semi-automatic equipment, involving some manual operation, resulting in low production efficiency. Furthermore, manual intervention can lead to quality control issues during valve installation, posing safety hazards to vehicles. Therefore, automating wheel hub valve installation has become an inevitable trend in the industry.

[0003] Currently, automated equipment is being applied to the installation process of wheel hub valves. Patent publication number CN109773557B discloses a dual-conveyor automatic valve installation device, which includes a wheel hub conveying mechanism for conveying the wheel hub, and sequentially sets a wheel hub centering station, a wheel hub detection and adjustment station, and a valve installation station along the conveying direction. It achieves centering positioning of the wheel hub during the conveying process through a wheel hub clamping and centering mechanism, collects the position information of the valve orifice through a camera device and drives the wheel hub to rotate to the set position, and finally, a robot installs the valve onto the wheel hub. Patent publication number CN207564073U discloses an automated wheel hub valve pressing device, including a transmission mechanism for conveying the wheel hub, a pressure measuring mechanism for driving the wheel hub and fixing its position, a pressing head mechanism for assembling the valve, and a feeding mechanism for providing the valve. It conveys the wheel hub via a roller conveyor, pushes the wheel hub between positioning rollers through a side pressing mechanism for positioning, and then the pressing head mechanism completes the pressing of the valve. In addition, existing technologies have also developed wheel hub valve hole recognition and positioning devices based on machine vision, which use image recognition technology to automatically detect and locate the valve hole position.

[0004] However, the existing automated valve installation equipment still has some shortcomings. During the installation process, it is often necessary to apply an appropriate amount of lubricating oil to the valve body surface to ensure smooth installation and reliable sealing. In addition, the integration level of traditional equipment is low, the overall structure of the equipment is relatively dispersed, it occupies a large space, and the connection efficiency between adjacent processes is low.

[0016] The outstanding and beneficial technical effects of this invention compared to the prior art are: This invention achieves continuous automated operation of the wheel hub from material loading, centering and positioning, valve hole detection, and automatic valve supply and installation through the organic integration of the conveying mechanism, centering mechanism, identification mechanism, and assembly mechanism. The tight coordination of each process reduces manual intervention, shortens the assembly cycle time of a single piece, and improves the overall production efficiency of valve installation. Furthermore, by integrating a waiting slot with an oil outlet and an oil spray block on the waiting plate, the valve stem can be immediately and quantitatively lubricated before entering the installation station. This ensures both the uniformity and timeliness of lubricant application and avoids the structural complexity and cycle time extension issues associated with adding an additional independent lubrication station. Combined with the precise detection of the valve stem hole position by the identification sensor and the drive of the valve stem pin by the multi-degree-of-freedom sliding assembly, the valve stem can be accurately installed into the corresponding hole, which helps ensure the sealing reliability and torque consistency after installation. Meanwhile, the centering mechanism drives the clamping rod through the centering synchronization link to achieve synchronous centering of the wheel hub. Together with the lifting top cone and the upper limit plate, it clamps the wheel hub longitudinally, which can effectively eliminate the positional deviation of the wheel hub during transportation and installation. This provides a stable positioning benchmark for identification and installation processes, thereby improving the consistency of the overall equipment operation and the installation quality.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 13 : An automatic valve inserter includes a frame 1, and further includes: The conveying mechanism 2 includes two sets of parallel conveyor frames 20 fixed on the frame 1, and a plurality of parallel conveyor rollers 21 are arranged between the two conveyor frames 20. The centering mechanism 3 includes a centering mounting plate 30 fixed between the bottoms of the two conveyor frames 20. The centering mounting plate 30 is provided with a centering clamping rod 31 that is synchronously driven by a centering synchronizing linkage. The identification mechanism 4 includes a clamping mounting plate 40 fixed above the frame 1, with the clamping mounting plate 40 positioned above the two conveyor frames 20. A longitudinally arranged clamping motor 41 is fixed on the clamping mounting plate 40, and the output end of the clamping motor 41 extends through the clamping mounting plate 40 and is fixed to an upper limit plate 42 at its end. A lifting mounting plate 43 is fixed on the frame 1 between the bottoms of the two conveyor frames 20. A longitudinally arranged lifting cylinder 43 is fixed on the lifting mounting plate 43, and a lower limit cone 44 is fixed to the output end of the lifting cylinder 43, with the lower limit cone 44 located below the upper limit plate 42. An identification mounting plate 5 is fixed on the frame 1 on one side of any conveyor frame 20, and an identification sensor 50 for detecting the hub nozzle hole is provided on the identification mounting plate 5. The assembly mechanism 6 includes a nozzle sliding base plate 60 fixed to the frame 1 and one side of the conveyor frame 20. A nozzle assembly cantilever 62 is mounted on the nozzle sliding base plate 60 via a sliding assembly 61, which allows for vertical and horizontal sliding towards the conveyor frame. The end of the nozzle assembly cantilever 62 is provided with a nozzle pin 63 for fixing the nozzle. A waiting seat plate 7 is fixed to the end of the nozzle sliding base plate 60. A waiting groove 70 for embedding the nozzle is provided on the waiting seat plate 7. An oil outlet 71 is opened on one side of the waiting groove 70. A linear guide rail 72 with a vertical vibrator at the bottom is fixed on the waiting seat plate 7. One end of the linear guide rail 72 abuts against the waiting groove 70, and the other end is connected to a vibrating plate 73 for storing materials.

[0019] The specific assembly process is as follows: like Figures 1 to 3 The wheel hub is placed manually or automatically by a feeding device (such as a robotic arm). It is continuously conveyed by the conveying roller 21 between the two conveying frames 20. After passing through the centering mechanism 3, the centering clamping rod 31 centers and clamps the wheel hub, placing it in the middle of the conveying line. When it reaches the identification mechanism 4, the lifting cylinder 43 lifts the wheel hub so that the upper end of the wheel hub abuts against the lower end face of the upper limit plate 42. Through the rotation of the clamping motor 41, the identification sensor 50 on the identification mounting plate 5 can effectively find the valve stem mounting hole on the wheel hub. In the further assembly mechanism 6, the valve stem assembly cantilever 62 drives the valve stem pin 63 to grasp the valve stem and install it into the identified valve stem hole.

[0020] During the process of grasping the valve stem, such as Figures 5 to 8 As shown, the valve stem is continuously fed by the vibratory plate 73 and further conveyed by the linear guide rail 72 with a straight vibrator, so that it can be embedded in the waiting groove 70. After the oil outlet 71 on one side of the waiting groove 70 effectively identifies that there is a valve in the groove, it performs effective oil injection, providing an automatic oil injection effect for valve stem assembly and effectively improving assembly efficiency.

[0021] Preferably, a longitudinally arranged waiting block base 74 is fixed on the waiting seat plate 7. A waiting block slider 75 is longitudinally slidably arranged on one side of the waiting block base 74 via a cylinder. The waiting groove 70 is opened at the upper end of the waiting slider 75. An air nozzle fuel injection block 76 is fixed above the side wall of the waiting groove 70. The oil outlet 71 is opened on the lower side wall of the air nozzle fuel injection block 76. The side wall of the air nozzle fuel injection block 76 is connected to a speed regulating connector 760 that communicates with the oil outlet 71.

[0022] In the above structure, the waiting groove is opened on the waiting slider 75, and the oil circuit does not interfere with the waiting slider 75. The oil circuit is detachably fixed above the waiting slider 75, and the oil is sprayed out through the bottom of the air nozzle oil injection block 76 and injected by falling. In addition, the air nozzle oil injection block 76 can be effectively disassembled for its own reasons during maintenance, preventing the oil outlet 71 from being blocked and unable to be repaired or replaced.

[0023] Preferably, a longitudinally arranged pressing cylinder 750 is fixed to the side wall of the waiting slider 75, a pressing rod 751 is fixed to the output end of the pressing cylinder 750, and a horizontally placed rubber pressing rod 752 is provided at the end of the pressing rod 751. The rubber pressing rod 752 is located above the waiting groove 70. When the valve nozzle slides into the waiting groove 70 through the linear guide rail 72, the pressing cylinder 750 drives the pressing rod 751 to move downward, and the rubber pressing rod 752 limits the valve nozzle.

[0024] Furthermore, the rubber pressure rod 752 can effectively press down on the valve stem, preventing it from shaking during oil injection, and the valve stem ejector pin 63 can effectively abut and grasp the valve stem during gripping, resulting in more accurate gripping. On the other hand, the rubber pressure rod 752 can press down on a single valve stem, preventing valve stem accumulation in the waiting groove 70 during feeding, thus ensuring continuous and stable operation.

[0025] It is worth mentioning that a sensor is installed on the waiting slider 75 to detect whether a valve stem is embedded in the waiting groove 70, so as to carry out the oil injection operation.

[0026] Preferably, the waiting slider 75 has an air passage 753. One end of the air passage 753 is located at the bottom of the waiting groove 70, and the other end is located on the side wall of the waiting slider 75 and connected to an air passage connector 754. The air passage 753 enables the adsorption of the valve and the ejection of air.

[0027] In the above structure, the air passage 753 is not only for the adsorption of the valve and the ejection of air, but also for the valve to rotate to a certain extent during the process of the rubber pressure rod 752 pressing down on the valve, so as to facilitate the even application of oil.

[0028] Preferably, the sliding assembly 61 includes a linear slide rail fixed to the valve sliding base plate 60, a linear slide plate 610 slidably mounted on the linear slide rail by means of a lead screw driven by a lead screw motor, a stand 611 fixed on the linear slide plate 610, a longitudinal slide rail provided on the stand 611, and the valve assembly cantilever 62 slidably mounted on the longitudinal slide rail by means of a lead screw driven by a lead screw motor; the end of the valve assembly cantilever 62 is provided with a bearing seat 620, the bearing seat 620 includes two bearing mounting plates 621, a pin motor 622 is provided on the side wall of any bearing plate 621, the output end of the pin motor 622 passes through the two bearing mounting plates 621, a rotating shaft seat 623 fixed to the output end of the pin motor 622 is provided between the two bearing mounting plates 621, a pin cylinder 624 is fixed on the rotating shaft seat 623, and the valve pin 63 is fixed on the piston end of the pin cylinder 624.

[0029] like Figures 9 to 11 As shown, the valve stem 63, the identification sensor 50, the waiting groove 70, and the lower limit cone 44 are all in the same plane, allowing the sliding assembly 61 to move in two directions within this plane. This enables the valve stem in the waiting groove 70 to be gripped and the valve stem mounting hole on the wheel hub to be effectively installed. Furthermore, a bearing seat 620 is provided on the valve stem assembly cantilever 62, allowing the rotating shaft seat 623 to rotate effectively with the spool motor 622. This not only facilitates the gripping of the valve stem but also adapts to the different tilt angles of the valve stem mounting holes caused by wheel hubs of different sizes.

[0030] Preferably, the conveyor frame 20 includes an input section 200 and an output section 201. The ends of the conveying rollers 21 in the input section 200 and the output section 201 are rotated in the same direction by a synchronous chain, and a drive motor is provided on the synchronous chain. The centering mechanism 3 is located below the input section 200. The lifting mounting plate 43 is fixed between the input section 200 and the output section 201.

[0031] In the above structure, such as Figure 12 As shown, the input section 200 uses a drive motor for continuous conveying and is equipped with an identification sensor to detect the hub status during conveying, effectively controlling the opening and closing of the drive motor. The conveyor frame 20 has a compact overall structure, with each mechanism connected to it, maximizing the overall space utilization of the equipment.

[0032] Preferably, the feed inlet of the input section 200 is provided with symmetrical guide plates 22, the two guide plates 22 are flared, and nylon plates are provided on the facing surfaces of the two guide plates 22. This can effectively achieve preliminary guidance during the placement of the wheel hub, providing certain convenience for the centering operation and avoiding excessive deviation.

[0033] Preferably, the synchronous connecting rod includes a connecting rod seat 32 fixed to the middle of the centering mounting plate 30. The centering mounting plate 30 is provided with a centering slide rail 33 parallel to the conveying roller 21. Centering slide plates 34 located on both sides of the connecting rod seat 32 are slidably mounted on the centering slide rail 33. A centering rotating rod 35 is hinged to the connecting rod seat 32. Centering connecting rods 36 with the same structure are respectively hinged to both ends of the centering rotating rod 35. The outer ends of the two centering connecting rods 36 are respectively hinged to the upper ends of the two centering slide plates 34. The centering clamping rod 31 is fixed to the upper end of the centering slide plate 34. A centering cylinder 37 for driving any centering slide plate 34 to slide along the centering slide rail is provided at the bottom of the centering mounting plate 30.

[0034] In the above structure, the use of a single centering cylinder 37 can effectively achieve the centering operation of the wheel hub, with fewer overall parts, and it is located at the bottom of the conveyor frame, thus occupying less space.

[0035] Preferably, the identification mounting plate 5 is provided with an identification slide rail 51 parallel to the conveying roller 21. An identification motor frame 52 driven by a lead screw motor is slidably mounted on the identification slide rail 51. An identification motor 53 is fixed on the identification motor frame 52, and the identification sensor 50 is fixed to the output end of the identification motor 52. The identification motor frame 52, which slides along the identification slide rail 51, can be effectively fine-tuned to adapt to the identification of wheel hubs of different sizes. Simultaneously, the identification sensor can rotate to a certain extent, further enhancing the fine-tuning effect.

[0036] Preferably, the frame 1 is box-shaped and includes a middle frame 10 for supporting the conveying mechanism 2 and the centering mechanism 3, a top bracket 11 for supporting the identification mechanism 4, and a bottom frame 12 for supporting the assembly mechanism 6.

[0037] In the above structure, and combined with Figure 1 and Figure 13 As shown, the frame is box-shaped and effectively covered by sheet metal, making the overall equipment more regular. At the same time, each mechanism can be compactly set in the frame 1, occupying little space and having more comprehensive functions, with a high degree of overall automation.

[0038] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
