Context & Challenges
The company faced several issues in the paint dispensing process on gear knobs:
- Irregular and non-repeatable dispensing
- Approximate robot positioning
- Manual cleaning required with solvents
- Scrap rate exceeding 25%
- Insufficient production throughput
- Complex and time-consuming robot programming
Implemented Solution
Deployment of a Janome robot to ensure precise needle positioning within the cavity to be filled. Integration of 8 syringes simultaneously to increase production throughput. Use of high-precision time-pressure dispensers for consistent and controlled dispensing.
Key Features:
- JANOME robot positioning accuracy of approximately 0.007 mm
- Design of specific tooling enabling integration of 8 syringes
- Janome software facilitating the creation, modification, and fine-tuning of programs
Equipment Used
- Janome JR3000 robot
- 300ETC time-pressure dispenser
JR3000
The JR3000 series from Janome is a line of industrial tabletop robots designed to enhance productivity and precision across various automated processes.
300 ETC
The 300 ETC digital dispensers offer precise time/pressure adjustment to ensure a constant product flow rate, along with dispensing time control accurate to the thousandth of a second.
Results & Benefits
- Highly precise positioning and dispensing
- Significant increase in production capacity
- Elimination of solvent use for cleaning
- Non-conformity rate reduced from 25% to less than 1%
