Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing and industrial anti-corrosion treatment, in particular to a magnetic ring coding identification cavity wax injection gun. Background Art

[0002] In modern industrial manufacturing, especially in the field of automobile manufacturing, anti-corrosion treatment of car bodies is a crucial process. During use, the car body will be exposed to different environmental conditions for a long time, such as moisture, mud, salt spray, etc., which can easily cause corrosion of metal parts, thus affecting the durability and safety of the vehicle. In order to improve the durability of the car body, anti-corrosion treatment is often achieved through methods such as wax injection and spraying. As an excellent anti-corrosion material, wax liquid can effectively isolate air and moisture and slow down the oxidation corrosion process. However, traditional wax injection equipment has poor spraying effect in parts of complex car body structures (such as gaps and grooves), and uneven coverage often occurs, resulting in unsatisfactory protection effect. Therefore, it is particularly necessary to develop an efficient and uniform wax injection equipment.

[0003] With the development of industrial automation and intelligence, the limitations of traditional manual wax injection equipment have gradually become apparent. Manual equipment is usually difficult to meet the precise spraying requirements of complex parts, and the operation is cumbersome and inefficient, making it difficult to adapt to the high-intensity production requirements of assembly line operations. Some automatic wax injection guns on the market have made improvements in structural design, attempting to improve the coverage effect by adjusting the spray angle and pressure, but there are still many problems: First, there is a lack of intelligent recognition capabilities, and the spray parameters cannot be automatically adjusted to adapt to different wax injection needs; second, there is a lot of wax liquid waste during the spraying process, which is difficult to meet environmental protection requirements; third, some wax injection equipment is large in size and is not suitable for spraying parts with small internal space or complex structures. These defects have hindered the widespread promotion of existing technologies in practical applications, and a more intelligent and accurate solution is urgently needed.

[0004] In order to overcome the above problems, the present invention proposes an intelligent wax injection gun assembly based on magnetic ring recognition technology, which can automatically identify and adapt to different wax injection requirements. By introducing a combination of a magnetic ring recognition unit and a read-write unit, the present invention can intelligently identify different wax injection rods and automatically adjust the injection parameters according to demand, thereby achieving quantitative, uniform and efficient wax injection. The mixed air spraying technology enables the wax liquid to form a uniform atomization when sprayed, so that it can cover complex car body parts. At the same time, the use of a high-precision flow control system can significantly reduce the waste of wax liquid, reduce operating costs and meet environmental protection requirements. The present invention not only effectively solves the limitations of traditional wax injection guns, but also fills the gap in the field of intelligent wax injection equipment in China, and provides a more efficient and intelligent technical solution for car body anti-corrosion treatment. Summary of the invention

[0005] The invention relates to a magnetic ring coding identification cavity wax injection gun, aiming to provide a wax injection device with the characteristics of intelligent identification, multifunctionality and high efficiency and energy saving, which can improve the wax injection effect, enhance the corrosion resistance of the car body, and fill the technical gap of domestic equipment in this field.

[0006] Technical Solution

[0007] The wax injection gun assembly includes the following structural components:

[0008] Magnetic ring identification unit: It is composed of an iron ring, a magnetic ring and a spacer, which are connected to the conversion joint in sequence. One end is connected to the quick connector male head, and the other end is connected to the quick connector assembly through the conversion joint. The magnetic ring identification unit is used to connect different wax injection rods. Each wax injection rod corresponds to a different magnetic ring. The magnetic ring information is identified by the read-write unit, so as to assign the corresponding wax injection parameters and realize the intelligent identification of different wax injection rods.

[0009] Magnetic ring guide sleeve: It is set outside the magnetic ring identification unit to guide and protect the magnetic ring, ensuring the stability and reliability of the magnetic ring during assembly and use.

[0010] Quick connector assembly: includes connector housing, button, connector, spring and connector sealing female head. The button and spring are assembled in the connector housing to achieve quick connection and disassembly. The connector sealing female head and connector are fixedly connected to the connector housing, and the flat nut G3 / 8 is connected to the connector to achieve sealing, which is convenient for replacing different wax injection rods and improves work efficiency.

[0011] Hanging nose: fixedly connected to the gun handle assembly, used to hang and support the entire assembly, making it easier for the operator to carry and place it during use.

[0012] Mixing valve assembly: including valve body, nozzle, spray needle, spray needle tail rod, spray needle spring nut, spray needle return spring, sealing gasket, combined rod seal and sealing ring tightening screw. The nozzle is connected to the valve body, and the spray needle is coaxially matched with the nozzle to achieve accurate wax liquid injection. The sealing component ensures that the wax liquid does not leak under high pressure, and the spray needle return spring automatically resets the spray needle to ensure the continuity and stability of the injection process.

[0013] The gun handle assembly includes the sheath, gun handle, trigger, trigger spring, iron sheet sensor, inductive proximity sensor, screws and pipeline fixing sleeve. When the trigger is pressed, the iron sheet sensor approaches the inductive proximity sensor, triggering the signal input to control the start of the wax injection system. The sheath and gun handle are connected by screws to ensure a stable structure. The pipeline fixing sleeve is connected to the mixing valve assembly by threads to fix the pipeline and connect the gas source and wax liquid.

[0014] Reader / writer unit: It is installed on the gun handle assembly and is used to read the magnetic ring information in the magnetic ring identification unit, identify different wax injection rods and assign corresponding wax injection parameters. The system can identify 32 bytes (232-1) of different wax injection rods, realize diversified wax injection operations, and greatly improve the flexibility and intelligence level of the system.

[0015] How it works

[0016] During use, the operator pulls the trigger, and the iron sheet sensor approaches the inductive proximity sensor, triggering the wax injection system to start. The system controls the output of compressed air and high-pressure wax liquid:

[0017] Compressed air: flows through the pipe fixing sleeve, through the gun handle assembly, enters the mixing valve assembly, opens the spray needle, and flows into the quick connector assembly.

[0018] High-pressure wax liquid: also flows into the quick connector assembly through the pipeline fixing sleeve, the gun handle assembly, and the mixing valve assembly.

[0019] The magnetic ring identification unit is connected to the quick connector assembly and connected to the corresponding wax injection rod (with different magnetic rings). The read-write unit identifies the magnetic ring information and assigns different wax injection parameters to achieve accurate wax injection for different workpieces.

[0020] Beneficial Effects

[0021] Powerful intelligent recognition function: It can recognize 2^32-1 different wax injection rods, realize accurate wax injection on different workpieces, and improve the flexibility and compatibility of the system.

[0022] Excellent spraying effect: It adopts mixed air spraying technology and uses high-pressure air to atomize the wax liquid, and the spraying is uniform. It is especially suitable for parts with complex structures, enhancing the corrosion resistance of the car body and extending the service life of the vehicle.

[0023] Environmental protection and energy saving: Through the high-precision flow meter, quantitative wax injection into the cavity is achieved, reducing wax liquid waste and meeting energy-saving and environmental protection requirements.

[0024] Easy to operate: The design of the quick connector assembly makes it easier to replace the wax injection rod. The nose-hanging design is easy to carry and operate. The overall structure is compact and comfortable to use.

[0025] Filling the technical gap: The present invention achieves a higher level of automation and intelligence in the field of wax injection equipment, effectively filling the gap in domestic equipment in this field and having broad application prospects.

[0026] The present invention provides a wax injection gun assembly with a reasonable structure, complete functions and convenient operation. Through the precise coordination between the components, an efficient and intelligent wax injection process is realized, which not only improves the work efficiency but also greatly improves the spraying quality. It has significant technical progress and practical value and is suitable for fields such as automobile manufacturing that require precise wax injection. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] Signal transmission:

[0092] The inductive proximity sensors 6-7 transmit the sensed signals to the control unit of the wax injection system, triggering the output of compressed air and high-pressure wax liquid.

[0093] Medium conveying:

[0094] Compressed air: enters the gun handle assembly 6 through the pipeline fixing sleeve 6-4, passes through the mixing valve assembly 5, pushes the spray needle 5-11 to open, and enters the magnetic ring identification unit 1 through the quick connector assembly 3.

[0095] High-pressure wax liquid: also passes through the pipeline fixing sleeve 6-4 and the gun handle assembly 6, enters the mixing valve assembly 5, mixes with the compressed air at the nozzle 5-3, and forms an atomized spray.
