Description

Technical Field

[0001] This utility model belongs to the technical field of electronic product processing equipment, and specifically relates to an automatic rolling production line for back cover plates. Background Technology

[0002] In the assembly and manufacturing process of electronic products such as smartphones and tablets, the bonding of the back cover is a crucial step. As one of the main appearance and structural support components of electronic products, the back cover plays a vital role in protecting the internal precision components. Currently, the mainstream process for bonding back covers generally adopts a pre-coated adhesive solution. This adhesive is usually pre-cut in a specific shape and bonded to the inside of the back cover. After the adhesive is bonded to the back cover, its adhesive properties (initial tack and final holding power) are usually in a "not fully activated" or "dormant" state. To achieve the designed adhesive strength and reliability, a Z-axis pressure perpendicular to the bonding surface must be applied during the bonding process. This process is called "bonding activation".

[0003] Currently, the "pressing activation" step is still largely completed on many production lines using manual Z-axis pressing. Skilled workers can achieve an efficiency of approximately 400 pieces / hour per person, while new employees can only manage about 200 pieces / hour per person. This high dependence on manual labor leads to unstable production efficiency. Furthermore, in a repetitive and fast-paced work environment, operators may experience fatigue or distraction, resulting in some workpieces not being pressed properly, which directly affects product usability.
