在工業(yè)生產(chǎn)的眾多環(huán)節(jié)中，封膠是確保產(chǎn)品密封性、穩(wěn)定性與耐久性的關(guān)鍵步驟。從建筑材料到電子產(chǎn)品，從汽車制造到包裝行業(yè)，封膠工藝無處不在。而全自動(dòng)封膠線的出現(xiàn)，更是革新了封膠作業(yè)模式，成為眾多企業(yè)提升生產(chǎn)效率與產(chǎn)品質(zhì)量的得力助手。

Sealing is a crucial step in ensuring the sealing, stability, and durability of products in various stages of industrial production. From building materials to electronic products, from automobile manufacturing to packaging industry, sealing technology is ubiquitous. The emergence of fully automatic sealing lines has revolutionized the sealing operation mode and become a powerful assistant for many enterprises to improve production efficiency and product quality.

一、工作原理深度剖析

1、 In depth analysis of working principle

全自動(dòng)封膠線以先進(jìn)的自動(dòng)化控制技術(shù)為核心，融合精密機(jī)械傳動(dòng)與精準(zhǔn)的膠水計(jì)量系統(tǒng)，實(shí)現(xiàn)封膠流程的全自動(dòng)化操作。其工作流程主要分為以下幾個(gè)關(guān)鍵環(huán)節(jié)：

The fully automatic sealing line is based on advanced automation control technology, integrating precision mechanical transmission and accurate glue metering system to achieve fully automated operation of the sealing process. The workflow mainly consists of the following key steps:

物料輸送：通過高精度的皮帶輸送機(jī)、鏈條輸送機(jī)或滾筒輸送機(jī)等，將待封膠的產(chǎn)品平穩(wěn)且準(zhǔn)確地輸送至各個(gè)工位。在輸送過程中，傳感器實(shí)時(shí)監(jiān)測產(chǎn)品位置，確保其精準(zhǔn)定位，為后續(xù)的封膠作業(yè)提供基礎(chǔ)。例如在電子元件的封膠中，傳感器可精確識(shí)別元件位置，保證膠水涂抹在指定區(qū)域。

Material transportation: The products to be sealed are smoothly and accurately transported to various workstations through high-precision belt conveyors, chain conveyors, or drum conveyors. During the conveying process, sensors monitor the position of the product in real-time to ensure its precise positioning, providing a foundation for subsequent sealing operations. For example, in the sealing of electronic components, sensors can accurately identify the position of the components, ensuring that the glue is applied to the designated area.

膠水供給與混合（針對(duì)雙組份膠水）：對(duì)于單組份膠水，儲(chǔ)膠桶直接通過管道與涂膠設(shè)備相連，利用氣壓或泵壓將膠水輸送至涂膠頭。而雙組份膠水則需要更復(fù)雜的供給系統(tǒng)，通過專門的比例泵或混合管，按照預(yù)設(shè)比例精確混合兩種膠水，確保膠水性能穩(wěn)定。像汽車車身密封膠的涂覆，雙組份膠水的精確混合能保證密封效果和強(qiáng)度。

Glue supply and mixing (for two-component glue): For single component glue, the glue storage tank is directly connected to the glue application equipment through a pipeline, and the glue is transported to the glue application head using air pressure or pump pressure. And two-component glue requires a more complex supply system, which precisely mixes the two types of glue according to the preset ratio through a specialized proportioning pump or mixing tube to ensure stable glue performance. The precise mixing of two-component adhesive, such as the application of car body sealant, can ensure the sealing effect and strength.

涂膠作業(yè)：這是封膠線的核心環(huán)節(jié)，根據(jù)產(chǎn)品的形狀、尺寸和封膠要求，選用不同類型的涂膠設(shè)備。如點(diǎn)膠閥適用于小劑量、高精度的點(diǎn)膠作業(yè)；噴射閥可實(shí)現(xiàn)高速、非接觸式涂膠，適用于對(duì)速度要求高的場景；螺桿泵則常用于高粘度膠水的均勻涂布。在手機(jī)外殼的封膠中，噴射閥能快速準(zhǔn)確地在外殼邊緣涂布膠水，提高生產(chǎn)效率。

Gluing operation: This is the core link of the sealing line, and different types of gluing equipment are selected according to the shape, size, and sealing requirements of the product. The dispensing valve is suitable for small dose, high-precision dispensing operations; The spray valve can achieve high-speed, non-contact adhesive coating, suitable for scenarios with high speed requirements; Screw pumps are commonly used for uniform coating of high viscosity adhesives. In the sealing of mobile phone cases, the spray valve can quickly and accurately apply glue to the edges of the case, improving production efficiency.

固化與檢測：涂膠完成后，產(chǎn)品進(jìn)入固化區(qū)域，根據(jù)膠水類型選擇合適的固化方式，如紫外線固化、熱固化或自然固化。固化后的產(chǎn)品通過視覺檢測系統(tǒng)或壓力檢測設(shè)備，檢查封膠質(zhì)量，包括膠線的寬度、高度、連續(xù)性以及密封性等，確保產(chǎn)品符合質(zhì)量標(biāo)準(zhǔn)。

Curing and Testing: After the adhesive is applied, the product enters the curing area and the appropriate curing method is selected based on the type of adhesive, such as UV curing, heat curing, or natural curing. After curing, the product is inspected for sealing quality through a visual inspection system or pressure testing equipment, including the width, height, continuity, and sealing of the adhesive line, to ensure that the product meets quality standards.

二、在各行業(yè)的應(yīng)用實(shí)例

2、 Application examples in various industries

建筑行業(yè)：在中空玻璃的生產(chǎn)中，全自動(dòng)封膠線發(fā)揮著不可替代的作用。它將丁基膠、聚硫膠或硅酮膠等密封膠均勻地涂布在玻璃邊緣，形成密封層，有效阻止空氣和水分進(jìn)入，提高中空玻璃的隔熱、隔音性能。例如山東廣匯力數(shù)控機(jī)械有限公司的 ZNJ2540 -Ⅰ/Ⅱ 中空玻璃全自動(dòng)封膠線，適合大規(guī)模玻璃深加工企業(yè)，能降低生產(chǎn)勞動(dòng)強(qiáng)度、節(jié)省人力，涂膠后玻璃周邊飽滿無氣線，角部充實(shí)，表面平整無需修角，還可配備兩套供膠系統(tǒng)，兩種密封膠切換快捷 。

In the construction industry, fully automatic sealing lines play an irreplaceable role in the production of insulating glass. It evenly applies sealant such as butyl rubber, polysulfide rubber, or silicone rubber on the edge of the glass to form a sealing layer, effectively preventing air and moisture from entering and improving the insulation and sound insulation performance of the insulated glass. For example, the ZNJ2540-I/II fully automatic sealing line for insulated glass from Shandong Guanghuili CNC Machinery Co., Ltd. is suitable for large-scale glass deep processing enterprises, which can reduce production labor intensity and save manpower. After coating, the glass perimeter is full and free of air lines, the corners are full, and the surface is smooth without the need for corner repair. It can also be equipped with two sets of adhesive supply systems, and the two types of sealants can be switched quickly.

汽車制造：汽車車身的密封和零部件的固定都離不開封膠工藝。全自動(dòng)封膠線用于涂抹車身密封膠、結(jié)構(gòu)膠等，提高車身的密封性、強(qiáng)度和耐久性。在汽車車燈的生產(chǎn)中，封膠線精確地在燈殼邊緣涂膠，確保車燈防水、防塵，延長使用壽命。

Automobile manufacturing: The sealing of car bodies and the fixation of components cannot be separated from the process of sealing with sealant. The fully automatic sealing line is used to apply body sealant, structural adhesive, etc., to improve the sealing, strength, and durability of the body. In the production of car headlights, the sealing line is precisely applied to the edge of the lamp housing to ensure that the headlights are waterproof, dustproof, and extend their service life.

電子領(lǐng)域：電子元器件的固定、電路板的防護(hù)等都需要高精度的封膠。全自動(dòng)封膠線為電子元器件涂抹固定膠、導(dǎo)電膠等，確保電子產(chǎn)品的穩(wěn)定性和可靠性。如在芯片封裝中，封膠線將膠水精確地涂覆在芯片周圍，保護(hù)芯片免受外界環(huán)境影響。

In the field of electronics, high-precision sealing is required for fixing electronic components and protecting circuit boards. The fully automatic sealing line applies fixing adhesive, conductive adhesive, etc. to electronic components to ensure the stability and reliability of electronic products. In chip packaging, the sealing line precisely applies glue around the chip to protect it from external environmental influences.
