Liquid crystal displays are widely used in various electronic products, such as mobile phones, computer displays, and the like. To prevent static charges from being present in the display housing and at the same time to provide a lower weight for the display, the housing of the liquid crystal display is typically made of plastic. Liquid crystal displays accumulate static charge on their surfaces during production and operation, and plastic housings do not release the accumulated static charge. Thus, by attaching a closed conductive film within the display housing, the closed conductive film is connected to ground via aluminum foil or wire, releasing the static charge in time.
The conductive film is a metal foil or conductive cloth with high conductive back glue, the conductive back glue and the conductive base material form a complete conductor, and the complete conductor can form electric lap joint and electric sealing of gaps with any metal surface in a bonding mode, and is widely applied to sealing electromagnetic shielding chambers, joints of a shell and electronic equipment, shielding by winding cables and the like, providing a reliable grounding surface and providing electric contact for surfaces which cannot be welded.
When the conductive film is manufactured, the conductive film is generally attached to a film carrier tape to form a conductive adhesive tape, and the conductive adhesive tape is wound into a roll so as to be convenient to transport and store. However, the wound conductive film is often bent and wrinkled, and the conductive film cannot be directly attached to the display, so that the conductive tape wound into a roll is typically unwound and stacked in a material box of the conductive tape, and then the conductive film is peeled off from the carrier tape by a film peeling mechanism.
When the stacked conductive tape is peeled off by the peeling mechanism, the conductive film is usually peeled off by being adsorbed on the surface of the conductive film by an adsorption head. The adsorption head is provided with adsorption holes, the adsorption holes are connected with the air pressure pipes, after the adsorption head is attached to the surface of the conductive adhesive tape, air in the adsorption holes is pumped out through the air pressure pipes, so that the air pressure in the adsorption holes is smaller than the atmospheric pressure, the adsorption head adsorbs the conductive film, and then the adsorption head is moved to strip the conductive film from the carrier film. However, there is a certain viscosity between the conductive film and the carrier tape, so that the adsorption head cannot smoothly peel the conductive film from the carrier tape when peeling the conductive film, which affects the peeling efficiency of the conductive film.
Based on the above, the invention provides the film stripping mechanism of the conductive adhesive tape, which can enable the conductive film to be stripped easily, thereby improving the stripping efficiency of the conductive film.
The following describes the film peeling mechanism of the conductive adhesive tape in detail through specific embodiments:
the embodiment of the application provides a film stripping mechanism of a conductive adhesive tape, as shown in fig. 1 and 2, comprising a base 1, a discharging assembly 2, a stripping assembly 3 and a first material taking device 4, wherein the discharging assembly 2 is used for discharging the conductive adhesive tape 400; the stripping assembly 3 is positioned at the downstream of the discharging assembly 2, the stripping assembly 3 comprises a stripping platform 31 and a stripping driving device 32, the stripping platform 31 is in sliding connection with the base 1, the stripping driving device 32 is connected with the stripping platform 31, and an adsorption structure is arranged on the stripping platform 31; the first extracting device 4 is located above the stripping platform 31.
When the conductive tape 400 is conveyed to the stripping platform 31, the adsorption structure can adsorb the carrier film of the conductive tape 400, the first material taking device 4 can adsorb the conductive film of the conductive tape 400, the stripping driving device 32 can drive the stripping platform 31 to linearly move along the first direction so as to strip the conductive film from the carrier film, and the first direction is opposite to the conveying direction of the conductive tape 400.
Before the conductive film is attached to the display screen, the coiled conductive adhesive tape 400 is unwound and stacked in the discharging assembly 2, then the conductive adhesive tape 400 in the discharging assembly 2 is placed on a film stripping mechanism, the conductive film of the conductive adhesive tape 400 is stripped from the film carrying belt by the film stripping mechanism, and the conductive film is placed in the conductive film material box, so that preparation is made for attaching the conductive film to the display screen.

It should be noted that, the position of the stripping assembly 3 downstream of the discharging assembly 2 means: along the conveying track of the conductive adhesive tape 400, the stripping assembly 3 is located downstream of the discharging assembly 2, rather than meaning that the stripping assembly 3 is located downstream of the discharging assembly 2 in a horizontal direction or a vertical direction.
Of course, when the stripping driving device 32 drives the carrier film to linearly move along the first direction X, the first material taking device 4 can adsorb the conductive film to move along the direction away from the conductive adhesive tape 400, so that the conductive film can be stripped from the carrier film relatively quickly, and the stripping rate of the conductive film is further improved.
In one possible implementation manner, the stripping driving device 32 includes a first cylinder 321, and a telescopic arm of the first cylinder 321 is connected with the stripping platform 31 to drive the stripping platform 31 to reciprocate linearly, so that when the stripping platform 31 moves along the first direction X, the conductive film can be stripped from the film carrier tape, and when the stripping platform 31 moves along the direction opposite to the first direction X and returns to the initial position, the conductive adhesive tape 400 can be continuously conveyed to strip the next conductive film.
As shown in fig. 2-4, the stripping platform 31 is slidably connected with the base 1 through the guide assembly 7, so that the stripping platform 31 can linearly reciprocate. The guide assembly 7 comprises a slider 33 fixed to the stripping platform 31 and a guide rail 34 fixed to the base 1, the guide rail 34 extending in the first direction X, the slider 33 being slidably engaged with the guide rail 34.
