Description

Technical Field

[0001] The present invention belongs to the technical field of piezoelectric glue spraying, and particularly relates to a piezoelectric glue spraying process for a special quick-drying glue. Background Art

[0002] In today's industrial production field, there are extremely high requirements for the coating operation of adhesives. Traditional pneumatic and screw valves expose many insurmountable problems when facing certain special glues. Taking AgCl glue as an example, its properties are very special, and ordinary pneumatic and screw valves cannot achieve smooth operation. This is mainly because the viscosity, curing characteristics, etc. of AgCl glue are different from those of conventional glues. In a conventional working environment, the glue is prone to nozzle blockage, uneven coating, etc., seriously affecting production efficiency and product quality. At the same time, AgCl glue needs to be heated during operation to achieve an ideal use effect. How to meet this special requirement has become a technical problem to be solved urgently. Summary of the Invention

[0003] In view of the above situation, to overcome the defects of the prior art, the present invention adopts a method of synchronizing glue spraying and heating, with stable glue volume control, improving the glue spraying efficiency and product quality.

[0004] To achieve the above object, the following technical solutions are adopted: The present invention provides a piezoelectric glue spraying process for a special quick-drying glue, including the following steps:

[0005] 1. Prepare a glue spraying device;

[0006] 2. Prepare AgCl glue and load it into the main body of the glue spraying device;

[0007] 3. Start the heater, use a piezoelectric valve to spray the heated glue, and the glue is heated when passing through the heater;

[0008] 4. Complete the glue spraying process.

[0009] Further, the glue spraying device includes a main body of the glue spraying device, a piezoelectric valve, and a heater. The piezoelectric valve is arranged below the main body of the glue spraying device, and the heater is arranged below the piezoelectric valve.

[0010] The beneficial effects of the present invention are:

[0011] Synchronous heating and glue spraying: The synchronous heating and glue spraying of the present invention ensure that the glue is always in the best operating temperature state at the moment of spraying, making the glue have appropriate fluidity, not being difficult to spray due to increased viscosity caused by too low temperature, nor affecting the chemical properties of the glue due to too high temperature, greatly improving the fluency of glue spraying and eliminating the problem of nozzle blockage caused by inappropriate temperature;

[0012] Precise control of the glue: Through the precise control of the piezoelectric valve, the glue volume ejected each time is ensured to be uniform and stable, thereby ensuring the quality stability and consistency of the product;

[0013] Enhanced bonding effect: During the glue spraying process, continuous heating enables the glue to quickly interact with the surface molecules of the target object when it comes into contact with the surface, enhancing the bonding effect of the adhesive. This is because the appropriate temperature accelerates the curing reaction rate of the glue, enabling it to adhere to the target object faster and more firmly, effectively improving the overall performance of the product.

The preferred implementation methods and materials described herein are only for illustrative purposes and do not limit the content of this application.

[0019] The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The test materials used in the following embodiments are all obtained from commercial channels unless otherwise specified.

[0020] Embodiment

[0021] A special fast-drying glue piezoelectric glue spraying process includes the following steps:

[0022] 1. Preparation of the glue spraying device:

[0023] The glue spraying device adopted by the present invention is a system that is carefully designed and integrated with a variety of key components, mainly composed of a glue spraying device body, a piezoelectric valve, and a heater.

[0024] The main body of the glue spraying device is the core load-bearing component of the entire system, and its design comprehensively considers multiple key factors. First of all, from the perspective of material selection, it is usually made of high-quality engineering plastics or metal materials, such as polytetrafluoroethylene or stainless steel. The main reason for choosing these materials is that they have good chemical corrosion resistance and mechanical strength, and can withstand the pressure and chemical erosion that may occur during the long-term storage and transportation of glue. At the same time, the physical and chemical stability of these materials ensures that the glue will not chemically react with the main body of the device during storage, ensuring that the original performance of the glue is not affected.

[0025] In terms of structural design, the internal structure of the main body of the glue spraying device has been optimized to ensure a smooth process of glue storage and transportation. The size and shape of its internal channels are carefully designed based on the principles of fluid mechanics, ensuring that the pressure loss during the flow of glue is minimized and preventing glue retention or uneven flow caused by unsmooth channels.

[0026] 2. Preparation and loading operation of AgCl glue:

[0027] The glue used in this process is AgCl glue, which is a glue with special properties. When selecting this glue, it is necessary to strictly control its quality, including key indicators such as the purity, viscosity, and chemical stability of the glue. Before loading the AgCl glue into the main body of the glue spraying device, it is necessary to strictly inspect the glue. Through professional testing equipment, such as viscometers and chemical analyzers, various performance indicators of the glue are tested to ensure that its performance parameters are within the predetermined range.

[0028] During the process of loading the glue, a special automated filling equipment is used. This equipment is matched with the injection port of the main body of the glue spraying device and can accurately inject the glue into the device body in a quantitative manner. In order to avoid introducing air during the filling process, the filling equipment adopts special liquid injection techniques, such as bottom liquid injection or slow and uniform liquid injection methods. Bottom liquid injection is to inject the glue through a special channel at the bottom of the device body, and use the gravity of the liquid to make the glue rise naturally to fill the device body, effectively avoiding the mixing of air; slow and uniform liquid injection controls the injection speed precisely, so that the glue can fully fill the space of the device body during the injection process, avoiding the generation of bubbles due to too fast flow rate.

[0029] After injecting the glue, to ensure the even distribution of the glue within the device body, the glue spraying device body needs to be placed on a stable platform and left to stand for a period of time. The length of this standing time is determined by the physical properties of the glue and the size of the device body, generally around [specific duration]. During this period, the glue within the device body will, due to the effects of gravity and surface tension, self-adjust its distribution state to achieve a relatively stable and even distribution. Meanwhile, the even distribution of the glue can be further promoted and the consistency of subsequent glue spraying operations improved by slightly vibrating the device body.

[0030] 3. Heater startup and piezoelectric valve glue spraying operation:

[0031] After completing the preparation and filling of the glue, starting the heater is one of the key operations in this process. The heater adopts innovative heating technologies, such as using ceramic heating elements, which have the advantages of fast heating speed, high thermal efficiency, and uniform heating. According to the characteristics of the AgCl glue, its heating temperature can be adjusted within the range of [starting temperature] to [ending temperature]. Through high-precision temperature sensors and advanced temperature control algorithms, the temperature of the glue can be accurately controlled within the optimal operating temperature range, with an error not exceeding ±[allowed error value] °C.

[0032] At the same time as starting the heater, the piezoelectric valve works in coordination with it. The piezoelectric valve is a precision component based on the piezoelectric effect. Its working principle is that when an external electric field is applied, the piezoelectric material will undergo a small deformation, thereby driving the opening and closing actions of the valve. This deformation is highly precise and repeatable, enabling the piezoelectric valve to accurately control the ejection volume and ejection frequency of the glue. In this invention, the coordinated work of the piezoelectric valve and the heater is the core mechanism for achieving precise glue spraying. When the heater heats the glue to the set temperature, the piezoelectric valve will eject the heated glue according to the pre-set glue spraying parameters, such as ejection frequency, ejection volume, and ejection time interval, etc.

[0033] During the process of the glue being ejected through the piezoelectric valve, the glue will pass through the heater again. This design is a key innovation point of this invention, ensuring that the glue remains in an ideal temperature state throughout the entire glue spraying process. Through this design, the glue is continuously heated when passing through the heater, thus ensuring that at the moment of ejection, the viscosity of the glue is in the best state, with excellent fluidity and no blockage in glue spraying due to temperature drop. Moreover, to ensure the reliability of this process, a heat insulation and heat preservation structure is designed between the heater and the piezoelectric valve to prevent excessive heat dissipation and avoid damage to the piezoelectric valve caused by overheating.

[0034] In addition, to further precisely control the glue spraying process, multiple sensors are also installed in the entire system. The pressure sensor is installed at key parts of the glue spraying device to monitor the pressure of the glue in real time. Based on the data feedback from the pressure sensor, the control system can dynamically adjust the opening time of the piezoelectric valve and the heating power of the heater to ensure that the spraying pressure of the glue remains stable. The flow sensor can accurately measure the spraying flow rate of the glue. When an abnormal flow rate is detected, the system will automatically adjust the action frequency of the piezoelectric valve or the heating intensity of the heater to ensure the uniformity and consistency of the glue spraying volume.

[0035] 4. Completion of the glue spraying process and subsequent treatment:

[0036] When the glue spraying operation is completed, the entire process enters the final completion stage. First, the control system gradually reduces the heating power of the heater to slowly lower the temperature of the entire system, avoiding damage to the device components caused by thermal stress due to sudden temperature drop. During this process, according to the pre-set temperature reduction curve, the power adjustment of the heater can be controlled through a program to ensure a smooth transition of the temperature.

[0037] After the system cools down, a comprehensive cleaning and maintenance work needs to be carried out on the glue spraying device. For the main body of the glue spraying device, a special cleaning solution is used. This cleaning solution has good solubility and cleaning ability for AgCl glue. By injecting the cleaning solution into the device main body and then performing a circulating rinse, the residual glue can be effectively removed. For the piezoelectric valve, it needs to be disassembled for detailed inspection, mainly checking whether there are physical damages or performance degradations in the piezoelectric elements, and at the same time checking and replacing the sealing components inside the valve to ensure that its sealing performance is not affected. For the heater, clean the attachments and impurities on its surface and check whether the heating element is working properly to ensure that its performance and efficiency are not affected.

[0038] The special fast-drying glue piezoelectric spraying process of the present invention has significant beneficial effects and technical advantages, and has strong innovation and practicality, which are specifically shown as follows:

[0039] 1. Synchronous heating and glue spraying:

[0040] From the perspective of process operation, the synchronization of glue spraying and heating is one of the core advantages of the present invention. Through the coordinated operation of the heater and the piezoelectric valve and the unique heating method, it is ensured that the glue is always in the optimal operating temperature state at the moment of spraying. This synchronization mechanism ensures that the glue has appropriate fluidity and avoids the problems caused by improper temperature control in the traditional glue spraying process. When the temperature is too low, the viscosity of the glue will increase significantly, making it difficult for the glue to be ejected from the piezoelectric valve, affecting the fluency and uniformity of glue spraying; while too high temperature may damage the chemical structure of the glue, affecting its bonding performance and chemical stability. The present invention effectively overcomes these problems through precise temperature control, improving the fluency and reliability of the glue spraying process.

[0041] 2. Precise control of the glue volume:

[0042] Since the present invention can precisely control the glue volume ejected each time, it ensures the quality stability and consistency of the product. In different industrial fields, the consistency of product quality is crucial. For example, in the electronics industry, for fine operations such as chip packaging or circuit board assembly, the amount and quality of the glue directly affect the performance and reliability of the product. The present invention ensures that the glue ejected each time meets precise requirements in terms of quantity and quality through the precise control of the piezoelectric valve and the synchronous heating of the heater, avoiding product defects caused by uneven glue usage or unstable quality, and improving the yield and performance stability of the product.

[0043] 3. Enhanced bonding effect:

[0044] The characteristic of continuous heating during the glue spraying process enables the glue to quickly interact with the surface molecules of the target object when it contacts the surface, enhancing the bonding effect of the adhesive. This is because the appropriate temperature accelerates the curing reaction of the glue, enabling the glue to adhere to the target object faster and more firmly. In the automotive manufacturing field, for the bonding of automotive parts, the present invention can make the glue closely combine with the part surface in a short time, improving the overall structural strength and safety of the vehicle; in the aerospace field, for the assembly of aircraft parts, this process can ensure that the glue still maintains good bonding performance under extreme conditions, improving flight safety and reliability; in the construction industry, for the bonding of building materials, the present invention can also play an important role, improving the firmness and durability of the building structure.

[0045] 4. High equipment reliability:

[0046] The glue spraying device of the present invention is designed with full consideration of the convenience of operation and the reliability of the system. By setting the piezoelectric valve below the main body of the glue spraying device, the flow path of the glue is optimized, reducing the energy loss during the flow of the glue; the heater is set below the piezoelectric valve, which not only ensures the heating effect of the glue but also avoids the adverse effects of heat on other components. At the same time, through the integrated sensors and control system, the operator can conveniently monitor and adjust the entire glue spraying process in real time. When abnormal situations occur, the system can issue an alarm in a timely manner, facilitating the operator to take corresponding treatment measures, greatly improving the production efficiency and product quality, and reducing the production cost and maintenance cost.

[0047] In summary, the piezoelectric glue spraying process of this special fast-drying glue and its supporting glue spraying device are a technology with high innovation and broad application prospects. Through the careful design of the glue spraying device, the strict control of the glue preparation process, the precise control of the glue spraying operation, and the improvement of the subsequent maintenance work, the present invention has demonstrated excellent performance in multiple industrial fields, providing an efficient, reliable, and stable glue spraying solution for the development of related industries, and is expected to promote the progress of industry technology and the improvement of product quality, with significant economic and social benefits.

[0048] Through the above unique process and device, the present invention solves many problems existing in the existing glue spraying technology, provides a new technical means for realizing high-quality and high-efficiency glue spraying operations, meets the strict requirements of different industrial fields for glue spraying processes, and has broad market application prospects and profound technical promotion value. In future industrial production, the present invention will play an important role in improving product quality, reducing production costs, and increasing production efficiency, and is expected to become the preferred glue spraying solution for many industries.
