As the core heat dissipation component of electronic devices and power machinery, the heat dissipation shell is widely made of lightweight metal materials such as aluminum alloy and steel. Its surface powder coating needs to have good corrosion resistance, thermal conductivity compatibility, and surface flatness. Traditional heat dissipation shell powder spraying relies on manual operation, which is affected by its hollow structure, thin-walled design, and multi cavity characteristics. It is prone to problems such as missed spraying, uneven coating, low powder recycling and utilization rate, and low production efficiency, making it difficult to adapt to large-scale standardized production needs.

Solution

The six axis powder spraying robot developed by Boming has core parameters adapted to the powder spraying scenario of the heat dissipation shell:

1. Load capacity: 10kg, can stably carry electrostatic powder gun, powder tube and detection sensor;

2. Repetitive positioning accuracy: ± 0.05mm, ensuring consistency of powder spraying trajectories for multiple batches of heat dissipation shells;

3. Arm extension range: 2100mm, covering the powder spraying range of 100-800mm specification heat dissipation shells, can penetrate deep into hollow cavities to complete operations;

4. Movement speed: The maximum joint speed is ≥ 222 °/s, and the powder spraying speed can be accurately adjusted between 60-180mm/s, balancing efficiency and coating uniformity.

Customer Case

An internationally renowned electronic equipment manufacturer

Pain point: The uniformity error of coating thickness does not exceed 0.08mm, but the efficiency of manual powder spraying is low, and the powder loss rate is as high as 50%, greatly increasing production costs

Solution: Establish a hanging powder spraying production line consisting of one Boming powder spraying robot.

Result: The uniformity error of coating thickness is ≤± 0.03mm, and the standard coating thickness is 50-80 μ m; No defects such as missed spraying, sagging, pinholes, bubbles, etc., with a coating coverage rate of 100% on hollow areas and inner cavities; Efficiency goal: One robot replaces 5-6 powder spraying workers, increasing powder utilization rate from 70% of manual labor to over 95%, and reducing powder loss of individual heat dissipation shells by 35%
