Especially in the automotive industry, the gas valve is used to control the flow of fuel, air or exhaust gas, and the quality and reliability of its welding parts are crucial to the safety performance of the entire system.

[0003] With the development of industrial automation, the assembly process of gas valves has gradually been mechanized and automated.

False welding refers to the phenomenon of weak welding or virtual welding caused by various reasons during the welding process, which will seriously affect the quality and reliability of gas valves.

[0005] At present, one way to deal with the problem of false welding is to clean and repair the welding parts through a brush mechanism. For example, the utility model patent with application number 202120187625.9 discloses a test device for printed circuit board production, in which a brush mechanism is used to clean the welding points. However, this method has the problem of low efficiency, because the brush mechanism needs to reciprocate in multiple directions and cannot be quickly switched between multiple stations, resulting in the overall assembly speed being limited.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 —4. In an embodiment of the utility model, an optimized assembly structure of an automatic valve assembly machine includes a base 1, a first positioning plate 2, a second positioning plate 3, a valve positioning seat 4, a valve 5, a brush mechanism 6, a bracket 7 and a cylinder 8.

[0032] The base 1 serves as the supporting foundation of the entire device and has sufficient stability and load-bearing capacity. Above the base 1, the first positioning plate 2 and the second positioning plate 3 are arranged in sequence, and a smooth rotation movement is achieved through bearings and stepper motors 12 known to ordinary technicians in the prior art. This rotary multi-station design allows the air valve 5 on each station to go through various assembly steps in sequence, thereby greatly improving the assembly efficiency; at the same time, by forming this multi-station, more functions can be achieved, such as Figure 4 The vibration plate 15 known to ordinary technicians in the field in the prior art can be used for vibration feeding, which belongs to the extended implementation method that ordinary technicians in the field can choose according to needs; and, for example, when feeding, a robot arm known to ordinary technicians in the field in the prior art can be introduced for clamping and placing, which belongs to the known prior art part.

[0033] The first positioning plate 2 is provided with a plurality of air valve positioning seats 4, which are evenly distributed according to a certain rule and match the shape and size of the air valve 5. The air valve 5 is connected to the positioning seat by a clamping method to ensure the stability and accuracy of the air valve 5 during the assembly process. At the same time, the welding part of the air valve 5 faces outward, which is convenient for subsequent welding and cleaning operations.

[0034] The brush mechanism 6 is one of the key components for handling the false welding problem. It comprises a brush wheel 14 and a motor 12 for driving the brush wheel 14 to rotate. The outer side of the brush wheel 14 contacts the welding part of the air valve 5, and the welding part is cleaned and repaired by rotating motion.

[0035] The second positioning plate 3 is fixedly provided with a bracket 7, and the bracket 7 is provided with a cylinder 8 and a brush mechanism 6. The cylinder 8 has a push-end position and a retracted position, and the brush mechanism 6 is driven to perform a cleaning operation or cancel the cleaning operation through the telescopic movement of the cylinder rod. For example, when a certain air valve 5 rotates on the air valve positioning seat 4 to a position that can cooperate with the brush wheel 14, the cylinder rod enters the retracted position from the push position, and the outer side surface of the brush wheel 14 fits with the welding part of the air valve 5 to ensure the cleaning effect.

[0036] In order to improve assembly efficiency and operation convenience, the first positioning plate 2 and the second positioning plate 3 can be driven to rotate by a stepper motor 12. The stepper motor 12 has a precise step angle and rotation speed, and can realize continuous operation of multiple stations. In addition, the number of the valve positioning seats 4 can be set according to actual needs, and preferably 8 in this embodiment.

[0037] In terms of mechanical structure, the diameter of the first positioning plate 2 is larger than that of the second positioning plate 3 to accommodate valves 5 of different sizes. Meanwhile, the cylinder 8 can be a cylinder 8 type having multiple push rods to achieve more stable pushing.

[0038] The motor 12 of the brush mechanism 6 is connected to the cylinder rod and the bracket 7 through the L-shaped connecting plate 9. The L-shaped connecting plate 9 has a bending plate 10 and another bending plate 11, wherein the bending plate 10 is fixedly connected to the cylinder rod, and the other bending plate 11 is fixedly connected to the motor 12. A brush wheel 14 is sleeved on the motor shaft 13 of the motor 12, and the brush wheel 14 is fixedly connected to the motor shaft 13 by fasteners to ensure the stability and reliability of the brush wheel 14 during rotation.

[0039] Through the above supplementary description, the solution of the utility model is more complete and clear. These improvements and optimizations not only improve the assembly efficiency and quality of the automatic assembly machine of the gas valve 5, but also reduce the production cost and maintenance difficulty, providing strong technical support for modern industrial automation production.

[0040] Embodiment 1:

[0041] In the context of modern industrial automation, the quality and assembly efficiency of the gas valve 5 as a key fluid control component are crucial to the operation of the entire production line. In the traditional assembly process of the gas valve 5, the problem of false welding has always been one of the main factors affecting product quality. Traditional treatment methods, such as using a brush mechanism 6 to clean and repair the welding parts, can solve the problem of false welding to a certain extent, but due to its low operating efficiency and complex mechanical movement, it can no longer meet the requirements of modern industry for high efficiency and high reliability.

[0042] The optimized assembly structure of the automatic valve assembly machine provided in this embodiment is designed as a rotating structure as a whole, and can handle false welding in sequence through the rotation of multiple stations without the need for frequent X-axis and Y-axis movements of the brush structure, thereby greatly improving the efficiency of handling false welding problems. Specifically, the structure includes key components such as a base 1, a first positioning plate 2, a second positioning plate 3, a valve positioning seat 4, a valve 5, a brush mechanism 6, a bracket 7, and a cylinder 8.

[0043] The base 1 serves as the supporting part of the entire structure, and a first positioning plate 2 and a second positioning plate 3 are arranged on the base 1 in sequence. The two positioning plates are driven to rotate by a stepper motor 12 to form multiple rotating stations. A valve positioning seat 4 is provided on each station to fix the valve 5. The valve 5 and the valve positioning seat 4 are connected by a snap connection to ensure the stability and accuracy of the valve 5 during the assembly process.

[0044] Compared with the traditional brush mechanism 6, the brush mechanism 6 in this embodiment is fixed on the bracket 7 through the cylinder 8, and the bracket 7 is fixed on the second positioning plate 3. The advantage of this design is that the cylinder rod of the cylinder 8 can move quickly between the push end position and the retracted position, driving the brush wheel 14 to efficiently clean the welding part. At the same time, since the entire structure is rotary, the brush mechanism 6 can easily switch between multiple stations with the rotation of the positioning plate, avoiding the complexity and inefficiency of frequent staggered movements such as the X-axis and the Y-axis in the traditional technology.

[0045] In addition, the present embodiment further improves stability and the ability to handle false welding problems by optimizing the number and layout of the gas valve positioning seats 4 and selecting a gas cylinder 8 with multiple push rods. These improvements not only make the overall structure more compact and reasonable, but also reduce production costs and maintenance difficulties.

[0046] In summary, the optimized assembly structure of the automatic valve assembly machine provided in this embodiment realizes efficient processing of the false welding problem by means of the overall design of a rotary multi-station structure and the use of the cylinder 8 to drive the brush mechanism 6 for efficient cleaning, and significantly improves the quality and assembly efficiency of the valve 5. Compared with the traditional technology, this embodiment not only has higher reliability and durability, but also can show better performance and adaptability under the high efficiency and high reliability requirements of modern industry.

[0047] The beneficial effects brought by the utility model will be more fully demonstrated in the following specific application scenarios and methods:

[0048] The utility model significantly improves the efficiency of handling false welding at welding parts during the automatic assembly of the gas valve 5 through a unique structural design and an integrated workflow, and effectively avoids the multi-position shift of the brush mechanism 6. Specifically, the beneficial effects of the utility model include the following points:

[0049] 1. Innovative use of rotary multi-station design: Compared with the traditional linear or fixed assembly structure, the rotary multi-station design of the utility model enables the gas valve 5 to go through various assembly steps in sequence within a single working cycle. This design not only reduces the footprint of the equipment, but also greatly improves assembly efficiency and reduces production costs.

[0050] 2. Optimized movement trajectory of brush mechanism 6: Traditional brush mechanism 6 usually needs to move back and forth in multiple directions to clean the welding part, which is not only inefficient but also easy to cause mechanical wear. However, the utility model can accurately control the telescopic movement of cylinder 8, so that brush mechanism 6 can quickly and accurately complete the cleaning task in a single direction, thereby significantly improving the efficiency of handling false welding.

[0051] 3. Realize fast switching between multiple stations: Due to the adoption of rotary design and optimized movement trajectory of brush mechanism 6, the utility model can realize fast switching between multiple stations, avoiding the cumbersome process of shifting brush mechanism 6 in multiple positions in traditional technology. This not only improves the overall operating efficiency of the equipment, but also facilitates the continuous operation of the automated production line.
