Technical Field

[0001] This utility model relates to the technical field of valve core assembly and testing, specifically to an automatic valve core assembly and testing device with high-frequency vibration assistance. Background Technology

[0002] During valve core assembly, the valve core and valve body often face installation difficulties due to their precise fit. Traditional manual assembly methods are inefficient, labor-intensive, and prone to misalignment due to operational errors, which can affect the valve core's sealing and fluid control functions. However, while existing automated assembly equipment can achieve partial automation, it lacks auxiliary mechanisms in the valve core assembly process: on the one hand, valve core feeding mostly adopts a single-layer feeding structure, which requires stopping work to replace the material tray, resulting in production interruption; on the other hand, after the valve core falls into the valve body, it is difficult for it to slide to the preset position on its own, and there is a lack of targeted auxiliary positioning methods, which easily leads to jamming or displacement problems. Therefore, this utility model provides an automatic valve core assembly and testing device with high-frequency vibration assistance to solve the above-mentioned problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic valve core assembly and testing device with high-frequency vibration assistance, comprising a frame, a jig tray, an assembly module, and a conveyor line; Also includes: The fixture tray is set on the conveyor line to carry the valve body. The assembly module includes a valve core feeding and assembly unit, a high-frequency vibration auxiliary unit and a vision inspection unit connected in sequence. The valve core feeding and assembly unit includes a double-layer alternating feeding mechanism and a valve core clamping assembly; The high-frequency vibration auxiliary unit includes a direct vibrator, an air blowing hole, and a brass guide sleeve. The brass guide sleeve is set corresponding to the valve core hole of the valve body.

The air blowing hole is set inside the brass guide sleeve to assist the valve core in positioning. A vision inspection unit is also provided on the side of the frame away from the double-layer alternating feeding mechanism.

[0005] Preferably, the dual-layer alternating feeding mechanism includes an easy-change tray, a sensor detection component, and a drive motor, which drives the upper and lower easy-change trays to feed materials alternately.

[0006] Preferably, the replaceable pallet is quickly replaced via a positioning pin, and the sensor detection component is used to monitor the pallet feeding status.

[0007] Preferably, the high-frequency vibration auxiliary unit also includes a lifting cylinder, which is used to lift the fixture tray during valve core assembly, and cooperate with the brass guide sleeve to achieve precise alignment between the valve core and the valve body.

Furthermore, the visual inspection unit can identify the assembly status in real time through the valve core inspection camera, thereby improving inspection efficiency and ensuring the consistency of product quality. 1. It is equipped with a double-layer alternating feeding mechanism. Through the setting of the double-layer alternating feeding mechanism, the material supply can be achieved without stopping production. Combined with the servo-driven valve core clamping component, the feeding and picking cycle is greatly shortened, avoiding the downtime waiting for materials problem of traditional single-layer feeding, adapting to the rhythm of mass production, and improving assembly efficiency and continuity. 2. Equipped with a high-frequency vibration auxiliary unit, the high-frequency vibration provided by the direct vibrator can help the valve core slide accurately into the preset position of the valve body. The brass guide sleeve and the air blowing hole further ensure the positioning accuracy of the valve core, effectively reducing assembly jamming and offset problems caused by precision fitting, and reducing the defect rate. 3. Equipped with a vision inspection unit, the assembly status is identified in real time through a valve core inspection camera. When paired with an NG sorting component, defective products can be quickly separated without the need for manual sampling inspection, which improves inspection efficiency and ensures the consistency of product quality.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 The present invention provides the following technical solution: To address the shortcomings of existing automated assembly equipment, which, while partially automated, lacks auxiliary mechanisms in the valve core assembly stage—namely, valve core feeding often employs a single-layer feeding structure, requiring downtime for tray replacement and causing production interruptions; and secondly, after falling into the valve body, the valve core struggles to slide autonomously to its preset position, lacking targeted auxiliary positioning methods and prone to jamming or misalignment—this solution proposes an automated valve core assembly and testing device with high-frequency vibration assistance. This device comprises a frame 1, a fixture tray 2, an assembly module, and a conveyor line. The fixture tray 2 is located on the conveyor line. The upper part is used to support the valve body. The assembly module includes a valve core feeding assembly unit, a high-frequency vibration auxiliary unit, and a vision inspection unit 14 connected in sequence. The valve core feeding assembly unit includes a double-layer alternating feeding mechanism and a valve core clamping assembly. The high-frequency vibration auxiliary unit includes a straight vibrator 10, an air blowing hole 12, and a brass guide sleeve 13. The brass guide sleeve 13 is set corresponding to the valve core hole of the valve body. The straight vibrator 10 provides high-frequency vibration to assist the valve core in sliding into the preset position of the valve body. The air blowing hole 12 is set in the brass guide sleeve 13 to assist the valve core in positioning. A vision inspection unit 14 is also provided on the side of the frame 1 away from the double-layer alternating feeding mechanism. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during use, the valve core is manually placed in the 5 interchangeable tray 3 of the double-layer alternating feeding mechanism. The drive motor drives the upper and lower interchangeable trays 3 to move alternately to the feeding position. The sensor detection component 4 monitors the feeding status of the interchangeable tray 3 in real time. The positioning camera 7 of the valve core clamping component takes pictures of the valve core for positioning. The brass clamping fingers 6 grab the valve core under the servo drive and transfer it to the fixture tray 2 on the conveyor line, which is above the valve body, to complete the valve core feeding and assembly stage. The high-frequency vibration auxiliary unit also includes a lifting cylinder 11, which is used to lift the fixture tray 2 during valve core assembly and work with the brass guide sleeve 13 to achieve precise alignment between the valve core and the valve body. Then, the lifting mechanism lifts the fixture tray 2, so that the valve core hole of the valve body is precisely aligned with the brass guide sleeve 13. The valve core clamping assembly includes brass clamping fingers 6, positioning camera 7, laser sensor 8 and drive cylinder 9. The valve core falls into the valve body through the brass guide sleeve 13. The vibrator 10 is activated and generates high-frequency vibration to help the valve core overcome the resistance of the precision fit and slide to the preset position. At the same time, air is blown through the air hole 12 in the brass guide sleeve 13 to further ensure the accurate positioning of the valve core. The conveyor line transfers the assembled valve core to the vision inspection unit 14. The servo drive module drives the valve core inspection camera to move and take pictures to identify the assembly status of the valve core. If the inspection is qualified, the fixture tray 2 continues to flow to the subsequent process. If the inspection is defective, the NG sorting assembly is activated to transfer the defective valve core to the NG box, completing the single automatic assembly and inspection process of the valve core.
