However, the existing pad printing equipment has some shortcomings in practical applications, which are mainly manifested in the following aspects:

[0003] 1. High dependence on manpower: Traditional pad printing equipment usually requires a lot of manual operation, especially in the process of loading, pad printing and unloading, which not only increases the labor cost, but also leads to low production efficiency. In addition, the repetitiveness and mechanical nature of manual operation are strong, which can easily cause operator fatigue and affect work quality;

[0004] 2. Low production efficiency: Due to the need for frequent manual intervention, the production rhythm of traditional pad printing equipment is limited, making it difficult to achieve efficient continuous production. This is an obvious bottleneck for companies that need large-scale production, directly affecting the overall efficiency and capacity of the production line;

[0005] 3. High failure rate: The existing pad printing equipment has a complex mechanical structure and many driving components (such as cylinders, motors, etc.), which makes the equipment have a high failure rate under long-term high-load operation. Frequent equipment failures not only increase the cost of repair and maintenance, but also lead to production stagnation, affecting the timely completion of production plans;
