Product Details

SMT PCB conformal coating dispensing machine

Conformal coating dispensing machine is a dispensing device specially used in industrial production, mainly used in the manufacturing process of products that require waterproof, dustproof and shockproof treatment. Its design and function are intended to ensure the durability and reliability of products under various environmental conditions by precisely controlling the release and shape of glue.

Ⅰ、 The main components of the conformal coating dispensing machine include

1. Glue supply system: usually includes glue barrel, glue pump, glue hose and pressure regulating device. The glue is pumped from the glue barrel to the dispensing head.

2. Dispensing head: It is a key component of the dispensing machine and is responsible for controlling the flow, speed and shape of the glue. The design of the dispensing head can adjust the pressure and injection mode of the glue according to the needs to achieve precise coating effect.

3. Motion control system: It includes motion track, motor, transmission device and control software, which is used to accurately control the movement trajectory of the dispensing head in three-dimensional space. These systems enable complex path planning and motion control to ensure that the glue covers the product surface evenly.

4. Trigger and detection device: used to detect and trigger the dispensing action, usually through sensors to detect the position of the product or through a visual system to monitor the dispensing effect in real time.

Ⅱ、 Anti-paint dispensing machines are widely used in the following major industries

1.Electronic industry: used for dispensing key components of mobile phones, tablets, TVs and other electronic products, such as circuit boards, electronic components, etc., to improve the waterproof performance and mechanical stability of the products.

2.Automotive industry: mainly used for dispensing automotive parts, such as lights, sensors, ECUs, etc., to prevent moisture and dust from entering the parts and improve the durability and reliability of the products.

3.Aerospace industry: used for the assembly of aerospace devices and equipment to ensure the stability and safety of the equipment in extreme environments and prevent vibration and external environment from affecting the equipment.

Ⅲ、 Technical features and advantages

Conformal coating is a specially formulated coating for PCB circuit boards, which is used to protect circuit boards and related equipment from environmental erosion. Conformal coating has good high and low temperature resistance; after curing, it forms a transparent protective film with excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, and corona-resistant properties. Conformal coating refers to the three protections: moisture-proof, dust-proof, and chemical corrosion-proof.

Advantages of using a coating machine to apply conformal coating:

1. The amount of paint (coating thickness accuracy is 0.01mm), paint position and area (positioning accuracy is 0.02mm) are set accurately,

2. No need to add people to wipe the board after painting. Some plug-in components have a large distance from the edge of the board, and can be directly painted without a fixture, saving board installation personnel.

3. No gas volatilization, ensuring the cleanliness of the working environment.

4. All substrates do not need to use a fixture to cover the carbon film to eliminate the possibility of collision.

Ⅳ、Configuration of three-proof paint dispensing machine

Suitable for conformal paint, silica gel, ink, lubricant, alcohol, paint

Equipped with stainless steel pressure barrel, high strength, good sealing resistance, non-sticky

Accurate atomization spraying parts without splashing, neat and beautiful edges
