As a critical piece of equipment in industrial production, the safety protection measures for multifunctional wedge bonding machines must cover the entire process before, during, and after operation, while also considering both the equipment's inherent safety design and personnel protection requirements. The following explanation focuses on four dimensions: equipment design, operating procedures, personnel protection, and emergency management.
The core safety design of the multifunctional wedge bonding machine revolves around its wedge-shaped structure. The wedge-shaped pressing area must be equipped with an adjustable protective baffle, and a mechanical interlock device must ensure that operators cannot access hazardous areas during the pressing process. For example, when the pressing plate descends, sensors must automatically detect whether the baffle is closed; if not, an emergency brake must be triggered. Furthermore, the equipment must integrate a real-time temperature and pressure monitoring system, using audible and visual alarms to alert operators to abnormal parameters and prevent equipment damage or material combustion risks due to overheating or overpressure. Transmission components, such as chains and gears, must be equipped with fully enclosed protective covers to prevent foreign objects from being caught in or accidental contact by personnel.
Operators must strictly follow the pre-start inspection procedures. Before starting the machine each day, check the hydraulic system, electrical control system, and heating module to ensure they are operating normally, paying particular attention to hydraulic oil leaks, aging wiring, and damaged heating elements. During operation, do not place any hard objects (such as scissors or rulers) on the worktable to prevent damage to the bonding belt or causing jamming. When placing materials, ensure their size is smaller than the bonding area to prevent material edges from getting caught in the transmission components. For example, the bonding pad should be smaller than the fabric to prevent glue residue from remaining on the belt and causing deformation of the tension roller. After operation, allow the equipment to cool completely before turning off the main power. Never force a stop using the emergency stop button to extend the equipment's lifespan.
Operators must wear full protective gear, including cut-resistant gloves, safety goggles, and anti-static clothing. Cut-resistant gloves prevent cuts from sharp materials, and safety goggles prevent coolant vapor or adhesive splashes from entering the eyes. Maintain good ventilation around the equipment, using an exhaust system to reduce the concentration of volatile organic compounds (VOCs) and minimize the risk of operators inhaling harmful gases. Meanwhile, a safety perimeter must be marked out in the work area to prohibit unauthorized personnel from entering and prevent accidents caused by misoperation.
Equipment must be equipped with an independent emergency stop button, and the button must be in a prominent and easily accessible location to ensure immediate power cut-off in case of emergencies (such as material jamming or abnormal equipment noise). During routine maintenance, the adhesive belt must be cleaned regularly, and the cleaning cloth of the descaling device must be replaced to prevent adhesive residue from causing belt misalignment. For the electrical system, insulation testing and wiring tightening must be conducted quarterly by professionals to prevent fires caused by poor contact. Furthermore, emergency exits around the equipment must be kept clear, and first-aid kits, fire extinguishers, and other emergency equipment must be provided. Regular fire escape and equipment malfunction handling drills should be organized for operators.
The company must provide systematic safety training to operators, covering equipment structure and principles, operating procedures, hazard identification, and emergency response measures. Trainees must pass an assessment before starting work and must undergo regular refresher training to update their safety knowledge. Simultaneously, an equipment safety responsibility system must be established, clearly defining the responsibilities of operators, maintenance personnel, and safety management personnel to ensure that safety measures are implemented effectively.
Safety protection for multifunctional wedge bonding machines should adhere to the principle of "prevention first, comprehensive management." This involves constructing a comprehensive safety assurance system through inherently safe equipment design, standardized operating procedures, enhanced personnel protection, and improved emergency management, thereby reducing accident risks and ensuring production safety.
