在工業生產的眾多環節中，封膠是確保產品密封性、穩定性與耐久性的關鍵步驟。從建筑材料到電子產品，從汽車制造到包裝行業，封膠工藝無處不在。而全自動封膠線的出現，更是革新了封膠作業模式，成為眾多企業提升生產效率與產品質量的得力助手。

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

全自動封膠線以先進的自動化控制技術為核心，融合精密機械傳動與精準的膠水計量系統，實現封膠流程的全自動化操作。其工作流程主要分為以下幾個關鍵環節：

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、鏈條輸送機或滾筒輸送機等，將待封膠的產品平穩且準確地輸送至各個工位。在輸送過程中，傳感器實時監測產品位置，確保其精準定位，為后續的封膠作業提供基礎。例如在電子元件的封膠中，傳感器可精確識別元件位置，保證膠水涂抹在指定區域。

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（針對雙組份膠水）：對于單組份膠水，儲膠桶直接通過管道與涂膠設備相連，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雜的供給系統，通過專門的比例泵或混合管，按照預設比例精確混合兩種膠水，確保膠水性能穩定。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：這是封膠線的核心環節，根據產品的形狀、尺寸和封膠要求，選用不同類型的涂膠設備。如點膠閥適用于小劑量、高精度的點膠作業；噴射閥可實現高速、非接觸式涂膠，適用于對速度要求高的場景；螺桿泵則常用于高粘度膠水的均勻涂布。在手機外殼的封膠中，噴射閥能快速準確地在外殼邊緣涂布膠水，提高生產效率。

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，產品進入固化區域，根據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。固化后的產品通過視覺檢測系統或壓力檢測設備，檢查封膠質量，包括膠線的寬度、高度、連續性以及密封性等，確保產品符合質量標準。

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、在各行業的應用實例

2、 Application examples in various industries

建筑行業：在中空玻璃的生產中，全自動封膠線發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入，提高中空玻璃的隔熱、隔音性能。例如山東廣匯力數控機械有限公司的 ZNJ2540 -Ⅰ/Ⅱ 中空玻璃全自動封膠線，適合大規模玻璃深加工企業，能降低生產勞動強度、節省人力，涂膠后玻璃周邊飽滿無氣線，角部充實，表面平整無需修角，還可配備兩套供膠系統，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。全自動封膠線用于涂抹車身密封膠、結構膠等，提高車身的密封性、強度和耐久性。在汽車車燈的生產中，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.

電子領域：電子元器件的固定、電路板的防護等都需要高精度的封膠。全自動封膠線為電子元器件涂抹固定膠、導電膠等，確保電子產品的穩定性和可靠性。如在芯片封裝中，封膠線將膠水精確地涂覆在芯片周圍，保護芯片免受外界環境影響。

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.
