[0002] With the popularity of smart phones and other electronic products, the bonding process of mobile phone shells has become a key process in the electronic manufacturing industry. In the traditional production process of mobile phone shells, the precision of the bonding process directly affects the appearance and functionality of the product, such as whether the scanning code and logo position of the mobile phone shell are accurately aligned. Existing bonding equipment mostly uses independent production lines to handle different models or different batches of products, which not only increases the procurement cost of the equipment, but also leads to problems such as large space occupation of the production line and low production efficiency.
[0003] In addition, the positioning accuracy and bonding quality of existing equipment are not satisfactory. In the production process, due to positioning errors or unstable temperature control, the bonded product often deviates, resulting in low yield and even a large amount of waste. Traditional bonding equipment often uses manual or semi-automatic operation, lacks high integration and automation, and results in more manual intervention in the production process, limiting production efficiency.
[0004] In order to solve the above challenges, the industry urgently needs a mobile phone shell bonding equipment that is integrated, high-precision, cost-saving and can improve production efficiency. Through innovative design, multiple key processes are concentrated on one equipment platform, and advanced visual detection and high-precision automatic transfer system are used, which can effectively solve the problems of positioning error, low efficiency and high cost in traditional equipment. Therefore, developing a mobile phone shell scanning code and logo position detection equipment with high precision, high efficiency and cost saving has important market value and practical application significance.
