Structure and Advantages of JERRYS Intelligent Sandblasting Robot System

JERRYS ROBOT

1.According to market demands, in the future, we will closely integrate industrial robot technology, vigorously enhance the automation and intelligence of sandblasting machines, with the core goal of liberating labor and improving productivity, and the purpose of reducing enterprise production costs, to accelerate the comprehensive layout of the surface treatment industry in the era of Industry 4.0 in China.

2.Using robots to replace manual sandblasting operations has advantages such as automation, high efficiency, stable operation, high sandblasting precision, and safety. Today, when arduous and dangerous manual sandblasting is gradually being replaced by automatic sandblasting technology, the robot sandblasting room cleaning solution has become an irreversible trend.

3.Automation: After inputting the workpiece code, the robot can automatically identify workpieces of various specifications and complete the sandblasting operation automatically, covering the entire surface at one time without manual assistance.

4.High efficiency: Sandblasting cleaning robots can work tirelessly, with efficiency many times higher than traditional manual sandblasting. Their uninterrupted operation in harsh environments also enables sandblasting cleaning robots to achieve significantly higher work efficiency.

5.Bridge-type sandblasting robot system

6.Stable operation: The robot is controlled by programming, ensuring stable operation. It is not affected by unstable factors such as fatigue, misjudgment, and emotional changes that may occur in manual sandblasting. The robot is equipped with an anti-collision device, which will automatically stop, reset, and trigger a system alarm in case of abnormal collisions.

7.High sandblasting precision: The robot has high sensitivity, stable operation, and a repeat path accuracy of up to 0.1mm, which is far beyond the reach of manual work. After sandblasting, the surface quality of the workpiece is very ideal, with excellent cleanliness and roughness, making it ready for direct painting or other treatments. Appropriate sandblasting pressure, a suitable distance between the nozzle and the workpiece, and an accurate sandblasting angle all directly affect the roughness and cleanliness. The sandblasting robot uses abrasives and air pressure suitable for the surface requirements of the workpiece. The distance and angle of the nozzle can be continuously adjusted to meet the customer's high-quality standards.

8.Safety: Manual sandblasting is extremely arduous, dangerous, and harmful to health. Operators have to endure noise and dust, and are prone to physical overwork. When handling large equipment, they also need to use ladders and workbenches, making the work even more dangerous. Operators must wear heavy, suffocating protective gear to protect themselves from abrasives flying at a speed of 200 meters per second. Manual sandblasting often leads to accidents and work-related injuries, causing production delays. Fewer and fewer people are willing to do this physically demanding and dangerous work, resulting in high staff turnover. Sandblasting robots can solve all the above problems. When operators manually control the robot, they sit in a humanized operating cabin with air conditioning and control the robot via a joystick. When the robot automatically cleans the workpiece, operators only need to monitor it in the control room outside the sandblasting room.

Process Requirements for Pre-treatment Before Powder Coating

Chemical pre-treatment methods can be adopted, including degreasing → derusting → cleaning → phosphating (or passivation), etc. For most workpieces that are rusty or have thick surface layers, mechanical methods such as sandblasting and shot blasting are used for derusting. However, after mechanical derusting, it is necessary to ensure that the workpiece surface is clean and free of scale.

Puttying: Apply conductive putty according to the defect level of the workpiece, and after drying, grind it smooth with sandpaper before proceeding to the next process.

Protection (also known as masking): If certain parts of the workpiece do not require coating, they can be covered with protective glue or other materials before preheating to avoid being sprayed with paint.

Preheating: Generally, preheating is not required. If a thicker coating is required, the workpiece can be preheated to 100～160℃, which can increase the thickness of the coating.

Process Parameters for Pre-treatment Before Powder Coating

1. Customer's requirements for coating quality: Generally, careful analysis of the overall quality of the samples or prototypes provided by the customer is required.

2. Condition of the object to be coated: Preliminary analysis should be conducted on the semi-finished products that the customer will produce, such as the properties of the material and its color absorption. The requirements and key points for pre-treating the surface of the semi-finished product before coating should be clarified.

3. Confirm the coating system: Analyze the surface effect of the coating based on the samples, including confirming the type of paint, color system, gloss, etc.

4. Existing conditions of the customer must be considered: The designed process should be based on the customer's existing conditions to ensure smooth implementation in their factory (such as equipment, construction environment, staff quality, etc.).

5. Planning of the coating process and preliminary evaluation of the coating time period.

6. Cost calculation and evaluation of the product.
