In a traditional glass bottle fire-polishing workshop, bottle preforms newly released from molds travel slowly along conveyors, radiating residual temperatures exceeding 800°C. Workers, clad in heavy heat-insulating suits, must endure 80°C+ heatwaves, dust, and noise, using heat-resistant rods to complete the precision polishing of bottle mouths at close range. Every operation carries the risk of burns and pushes physical endurance to the limit.

This is the “choke point” of production and a “Flaming Mountain” for worker health. Difficulty in recruitment, high turnover, fluctuating efficiency, and safety hazards—the fire-polishing process has become the last “hard nut to crack” in the automation upgrade of the glass manufacturing industry.

Can automated equipment withstand such a harsh environment? Atomrobot’s High-Temperature Series delta robots, validated by actual production line performance, provide a definitive “Yes.”

Technical Challenge: Testing Automation in Extreme Heat
 

It is well known that in glass fire-polishing workshops, ordinary robots often “don’t last three days.” The lethality of high-temperature environments to automation equipment manifests on multiple levels:

• Electronics: Heat dissipation becomes difficult, leading to performance degradation or total hardware failure.
• Mechanics: Thermal expansion and contraction cause mechanical arm deformation, rapidly deteriorating repeatability.
• Sealing: Seals harden and crack under high heat, allowing dust to infiltrate bearings and accelerate wear.

To operate stably in such conditions, a robot must be specifically engineered in terms of materials, cooling, and structure.

The Solution: Specialized Design for High-Temperature Conditions
 

Atomrobot’s high-temperature series delta robots have undergone forward R&D specifically for high-heat scenarios, from materials and structure to cooling systems:

1. Dual Main-Arm Linkage Architecture

The robot utilizes independent motors to drive dual main arms. Through precise algorithms, the two arms rotate synchronously, coordinating with a spline screw to move the end-effector through complex 3D displacements. Compared to traditional single-arm structures, the dual-arm design not only enhances payload capacity but also ensures jitter-free motion during high-speed operation—perfectly matching the high-cycle requirements of glass bottle transport.

2. Full-Link Closed-Loop Cooling System

To handle extreme conditions where ambient temperatures exceed 80°C, we have customized a closed-loop cooling system. Utilizing a cold-air dissipation scheme, internal circulation channels precisely cover the motors, reducers, and core control modules. This ensures that core components maintain a constant operating temperature even under continuous “baking.” Field tests show this design extends equipment life by over 30% and prevents overheating-induced downtime.

3. High-Temp Materials & Aerospace-Grade Aluminum Body

Critical transmission components utilize special high-temperature resistant bearings and seals, allowing them to maintain excellent mechanical performance and control precision even under the 800°C radiant heat from the glass bottles. The main body is constructed from 7075 high-strength aerospace-grade aluminum alloy. Treated with pre-stretching, it achieves IT6-level dimensional accuracy. This lightweight design increases motion response speed by 20% while ensuring stability during high-speed cycles.

Application Scenarios: Field Performance Data
 

According to real-world data from the current high-temperature glass project, the performance of the Atomrobot High-Temperature Series is as follows:

• Visual Identification: High-precision vision systems identify various glass bottle specifications on the conveyor in real-time. Even with random positional shifts, the robot locks onto targets with a ±0.1 mm gripping accuracy.
• Cycle Time: The dual main arms work in synergy to transport high-temperature preforms to the fire-polishing station at a rate of 16 cycles per minute.
• Placement Precision: Repeatability reaches ±0.05 mm, ensuring the bottle mouth is perfectly aligned with the flame for consistent polishing quality.
• Reliability: In ambient temperatures over 80°C, the equipment has achieved 24/7 continuous operation without a single overheating failure, keeping core component temperatures strictly within permissible ranges.

Customer Value: Safety, Cost Reduction, and Efficiency
 

According to customer feedback, the application of this series has demonstrated significant economic benefits:

• Labor Savings: A single unit can replace 2 to 3 workers, enabling 24-hour production unaffected by labor turnover. Based on current labor costs, the equipment investment is expected to be recovered within 6 months.
• Quality Control: The ±0.05 mm repeatability far exceeds manual capabilities, ensuring uniform fire-polishing, improved bottle mouth finish, and a significantly lower defect rate.
• Worker Welfare: Automation has fundamentally transformed the working environment. High-risk roles previously exposed to heat, dust, and noise are now shifted to remote monitoring in air-conditioned control rooms. This eliminates occupational health hazards such as heatstroke and respiratory issues, enhancing the company’s safety management and social responsibility image.
• Flexibility: The integrated vision system adapts to different bottle diameters and heights. Combined with rapid changeover programs, it flexibly meets the demands of small-batch, multi-variety production.

Reshaping Industrial Temperatures: Returning Technology to Humanism
 

Withstanding limits of 80°C+ ambient and 800°C radiant heat, Atomrobot’s challenge in the glass fire-polishing field proves once again: Automation is not a cold replacement, but a respect for humanity and the creation of a better life. It keeps workers away from danger, makes production more efficient, and makes quality more stable.
