The utility model discloses a tab rubber structure, tab rubber tape and tab rubber production device, include: base material layer has along the first surface and second surface opposite to layer thickness, composite adhesive layer is divided and is located at the first surface and second surface, base material layer is provided with the anti -overflow through -hole along the layer thickness and is penetrated, and the interval between adjacent anti -overflow through -hole along the transverse and longitudinal direction of base material layer is equal, or the interval between adjacent anti -overflow through -hole along the longitudinal direction of base material layer is less than the interval between adjacent anti -overflow through -hole along the transverse of base material layer, composite adhesive layer includes the connecting layer close to base material layer, and the top of at least one connecting layer is provided with recessed portion, and the bottom of recessed portion is matched with anti -overflow through -hole concave -convex. Base material layer guarantees structural stability and is provided with anti -overflow through -hole simultaneously, after with composite adhesive layer compound, when tab and thermoplastic film heat seal, after heating, composite adhesive layer melts and flows and is connected and forms the even surface, not only solves its overflow problem, and has improved the connection firmness between two composite adhesive layers.

This utility model discloses a voice coil motor and a camera device. The voice coil motor includes a base, a housing, and an adhesive. The base has a hollowed-out central area forming a receiving space. The base has multiple outer side walls, with the lower edges of the outer side walls protruding outwards to form a raised structure. The housing is fitted onto the outer side walls of the base, with its lower edge matching the raised structure. The adhesive is located between the housing and the base, and the raised structure protrudes outwards relative to the housing by a certain distance. Therefore, the voice coil motor, through the base and housing, prevents adhesive from overflowing into the receiving space, while increasing the surface area available for bonding, thus helping to avoid product defects.

The invention discloses a self-adhesive label preparation method based on gel state transfer coating, which comprises the following steps: coating a first release carrier with a hot-melt pressure-sensitive adhesive heated to a melt flow temperature to form a melt adhesive layer on the surface of the first release carrier; cooling the molten glue layer to a gelation temperature in a gradient manner, and gelating the molten glue layer from outside to inside to form a gel-state glue film; after the gel-state adhesive film and the label plane material are laminated, the first release carrier is stripped, so that the gel-state adhesive film on the first release carrier is transferred to the label plane material, and an adhesive surface layer is formed on the surface of the label plane material; and compounding the adhesive surface layer with a second release carrier to obtain the self-adhesive label. The phenomenon of glue overflowing is effectively avoided, long-time high-temperature curing or preparation of middle double-sided adhesive tape needed by a traditional hot melt glue process is not needed, and online continuous efficient production from coating to finished product can be achieved.
