SJJM-ROBOT01 type auxiliary room cleaning robot is mainly used for automatic cleaning of the inner wall of the single crystal furnace auxiliary room. It uses a climbing robot and a cleaning head with a rotating and tensioning head to climb to the upper end of the auxiliary room and the tensioning mechanism opens before starting cleaning. The robot gradually descends during the cleaning process to clean the debris on the inner wall of the auxiliary room, replacing manual work.

Applicable products: Single crystal furnace auxiliary room:
1. Inner diameter of the secondary chamber of the crystallization furnace: 410mm
2. Height of the secondary chamber of the crystallization furnace: 5800mm+1300mm=7100mm (distance from the bottom opening of the secondary chamber to the top);
3. The lower eaves of the auxiliary room are 1200-2200mm above the ground.

Robot composition
1. Robot platform: Manually move the platform, equipped with UPS power supply, to achieve free movement in all directions.
1) Power management: UPS power supply, stable and reliable, with audible warning of low battery level, and comprehensive battery management strategy; Charging comes with an external socket that can meet the charging voltage of AC-220V.
2) Motion control manual mode, manual push.
3) The steering mechanism includes universal wheels, which are positioned to the working position according to different auxiliary chamber positions. The wheels are equipped with a locking mechanism to ensure no displacement during operation. The wheels are made of silicone wear-resistant material.

2. Crawling robot:

Adopting a hollow spider crawling design, it is a professional pipeline crawling robot design solution at present. The robot is controlled by PLC and microcontroller, and automatically starts working when reaching the upper part, and can stop at any time during the process.
Laser sensor, automatically judges when it reaches the upper part. Mechanical limit sensor to prevent accidental crawling and rising. The side opening design allows for the insertion of tungsten wire rope without removing a heavy hammer.

3. Cleaning mechanism:

The cleaning head is composed of two semicircles, which can be retracted and extended, detachable, and can be rotated clockwise or counterclockwise at 25 ° for cleaning.
1) Non woven fabric fixing mechanism: mechanically fixed, convenient and detachable.
2) Rotating mechanism: driven by a motor, powered by UPS power supply; It can perform a 45 degree reciprocating rotation to achieve cleaning while descending.
3) Tensioning mechanism: The tension or contraction action is controlled by a motor, and the power source is from the UPS power supply.
4) Dust removal device: composed of a micro vacuum cleaner and filter, powered by a UPS power supply.
5) Alcohol spraying: Peristaltic pump automatically sprays alcohol.

4. Cleaning platform:

Using manual assistance, manually push the cleaning robot under the auxiliary room to assist in cleaning
The robot enters the auxiliary room and the cleaning robot automatically adjusts vertically and horizontally.

5. Crawling robot frame:

Made of aviation aluminum material, with a lightweight design and excellent rust resistance and related anti-corrosion treatment.

6. Electrical control part:

Touch screen control, stop switch, descent switch, ensuring that the crawling robot can smoothly detach from the auxiliary room in any fault. It also includes PLC, microcontroller handheld smart screen, and other electrical equipment.

7. Human machine interface:

Use buttons and displays to display the current cleaning situation and indicate safety status, automatic working status, manual control status, and user-friendly design.

8. Safety settings:

① Stop button, emergency stop in case of malfunction.
② Two sets of control systems ensure that the crawling robot can be smoothly removed from the auxiliary room in case of communication failure.
③ Automatic prompt cleaning robot maintenance system.

Basic specifications:
① Dirt and cleaning method in the auxiliary room: volatile matter and dust, no sharp particles, clean with a dust-free cloth and alcohol;

② Mechanical movement speed: lifting speed: rising>3m/min, falling (during cleaning)>3m/min (formula adjustable);

③ Cleaning robot platform: 800mm × 1000mm × 1200mm；

④ Ground flatness adjustment tolerance: ± 20mm；
