Application Sharing | How to solve mechanical safety problems with minimal cost in the automotive industry?

Automobile manufacturing is a high-precision and highly automated industry, and its four core processes - stamping, welding, painting, and final assembly - constitute the main line of vehicle production, which is efficient but also high-risk!

Automobile Manufacturing - High Risk Points

1. Abnormal movement system

Risk of heavy machinery: Stamping machines with a capacity of 2000-3000 tons operate at a high speed of 30-40 times per minute. Once operated incorrectly or protected, it is extremely easy to cause serious accidents such as compression and shear injuries.

Welding robot risks: High speed moving robotic arms may cause collision and compression injuries due to program errors and sensor failures.

2. Electrical system malfunction

Welding hazards: High current welding operations may cause short circuits, arc burns, and even electrical fires.

Automated spraying equipment: Short circuit/open circuit of the equipment circuit may cause mechanical failure, leading to risks such as mechanical injury and production interruption.

Assembly of robotic arm: When manual assembly and automation equipment work together, if the safety grating fails or the emergency stop fails, it may cause injury or impact accidents.

3. Mechanical mechanism failure

Hidden dangers in material transportation: If the automated feeding system experiences jamming or misalignment, it may cause mechanical chain failures, posing a threat to the safety of operators.

These faults can easily lead to mechanical injuries to operators, secondary damage to precision equipment, cascading shutdowns of the entire production line, and other chain reactions .....

Safety Relay - Necessity

Safety relays can detect real-time issues such as line disconnection, contactor faults, safety actuator faults, short circuits, etc.

When abnormal events occur during the welding, stamping, assembly, and painting production processes, the power supply should be reliably cut off or the safety protection function should be triggered to achieve the protection purpose.

Safety Relay - Protection Mechanism

When there is an abnormal danger on the production line:

·Personnel entering hazardous areas

·Equipment malfunction or unexpected situation

Safety relay protection mechanism:

1. Emergency signal triggered

Automatic triggering of emergency stop signal through safety sensors such as safety light curtains and safety interlock switches.

The equipment immediately enters a safe state and urgently stops the operation of the production line.

2. Emergency stop function

Quickly cut off the power or control circuit of dangerous equipment such as robots, welding equipment, conveyor belts, stamping machines, etc.

The redundant circuit design of Bytorent ensures dual effects to ensure safe shutdown of the system.

3. Self inspection and fault protection

Real time self diagnostic function can detect issues such as wire breakage, short circuit, or poor contact in the emergency stop circuit, and lock the output when a fault occurs to prevent equipment from starting incorrectly.

Bytorent safety relays comply with TUV functional safety certification standards and IEC 62061 SIL 3 safety standards, ensuring high reliability of the system.

4. Reset and secure restart
