Background

Liquid crystal displays are widely used in various electronic products, such as mobile phones, computer monitors, and the like. In order to prevent static charges from being present in the display housing and to provide a display having a low weight, the housing of a liquid crystal display is generally made of plastic. The liquid crystal display device accumulates stored static charges on its surface during the production and operation, and the plastic housing cannot discharge the accumulated static charges. Therefore, the closed conductive film is attached to the display housing, and the closed conductive film is connected to the ground line through the aluminum foil or the wire, so that static charges can be discharged in time.

Before the conductive film is attached to the display, the conductive film is attached to a carrier tape and wound to form a conductive tape, and the wound conductive tape is 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 conductive tape placed in a stacked state is peeled off the conductive film on the peeling mechanism, the conductive tape is usually adsorbed to the surface of the conductive film by an adsorption head to peel off the conductive film.

However, the conductive film and the film carrier tape usually have a certain viscosity, so that the adsorption head cannot smoothly peel the conductive film from the film carrier tape when the conductive film is peeled, and the peeling efficiency of the conductive film is affected.

The conductive film is a metal foil or conductive cloth with a high-conductivity back adhesive, the conductive back adhesive and a conductive base material form a complete conductor, and the complete conductor can be electrically connected with any metal surface in a bonding mode to form electrical lap joint and gap electrical sealing.

In manufacturing the conductive film, the conductive film is usually attached to a film carrier tape to form a conductive tape, and the conductive tape is wound into a roll for convenient transportation and storage. However, the wound conductive film is usually bent or wrinkled, and the conductive film cannot be directly attached to the display, and therefore, the conductive tape wound into a roll is usually unwound and stacked in a magazine of the conductive tape, and then the conductive film is peeled off from the film carrier tape by a film peeling mechanism.

When the stacked conductive tape is peeled off by the peeling mechanism, the conductive tape is usually adsorbed on the surface of the conductive film by an adsorption head to peel off the conductive film. The adsorption head is provided with an adsorption hole, the adsorption hole is connected with the air pressure pipe, after the adsorption head is attached to the surface of the conductive adhesive tape, air in the adsorption hole is pumped out through the air pressure pipe, the air pressure in the adsorption hole is smaller than the atmospheric pressure, so that the adsorption head adsorbs the conductive film, and then the adsorption head is moved to strip the conductive film from the film carrying belt. However, the conductive film and the carrier tape usually have a certain viscosity, so that the adsorption head cannot smoothly peel the conductive film from the carrier tape when the conductive film is peeled, which affects the peeling efficiency of the conductive film.

Based on the structure, the invention provides the film stripping mechanism of the conductive adhesive tape, which can enable the conductive film to be stripped easily, so that the stripping efficiency of the conductive film is improved.

The film peeling mechanism of the conductive adhesive tape is explained in detail by specific examples below:

the embodiment of the application provides a film peeling mechanism for a conductive adhesive tape, as shown in fig. 1 and fig. 2, the film peeling mechanism comprises a base 1, a feeding assembly 2, a stripping assembly 3 and a first material taking device 4, wherein the feeding assembly 2 is used for discharging the conductive adhesive tape 400; the stripping component 3 is positioned at the downstream of the feeding component 2, the stripping component 3 comprises a stripping platform 31 and a stripping driving device 32, the stripping platform 31 is connected with the base 1 in a sliding manner, 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 material extracting device 4 is located above the stripping platform 31.

The above stripping assembly 3 located downstream of the emptying assembly 2 means: the stripping assembly 3 is located downstream of the discharging assembly 2 along the conveying track of the conductive adhesive tape 400, rather than the stripping assembly 3 being located downstream of the discharging assembly 2 in the horizontal direction or the vertical direction.

Certainly, when the peeling-off driving device 32 drives the film carrier tape to move linearly along the first direction X, the first material taking device 4 can absorb the conductive film to move along the direction away from the conductive tape 400, so that the conductive film can be peeled off from the film carrier tape more quickly, and the peeling speed of the conductive film is further improved.

The base plate 11 comprises a bottom plate and side plates, the side plates comprise a first side plate 12 and a second side plate 13, the first side plate 12 is fixedly connected with the bottom plate, and a reinforcing plate is connected between the first side plate 12 and the second side plate 13, so that the base plate 11 is more stable.

Of course, the screw rod may be replaced by a rack, a belt, a chain or a gear, as long as the motor can drive the peeling platform 31 to linearly reciprocate, which is not limited herein.

As shown in fig. 5, the adsorption structure includes an adsorption hole 311 opened on the upper surface of the peeling platform 31, and the adsorption hole 311 is communicated with a vacuum extractor to extract the gas in the adsorption hole 311. Specifically, the adsorption holes 311 are arranged in an array on the upper surface of the stripping platform 31, a plurality of air suction holes 312 are formed in one side of the stripping platform 31, the air suction holes 312 are arranged in sequence along the width direction of the stripping platform 31, each air suction hole 312 is communicated with one column of adsorption holes 311, each air suction hole 312 is correspondingly connected with a vacuum tube through a joint, the vacuum tube is connected with a pressure reducing valve, the pressure reducing valve is connected with a pressure reducing valve pressure gauge, the adsorption holes 311 are vacuumized by the control vacuum tube, and therefore a film carrying belt located on the stripping platform 31 can be adsorbed.

The shape of the adsorption hole 311 may be various, and may be a circular hole, an elliptical hole, or a polygonal hole, as long as the adsorption hole 311 can adsorb the film carrier tape after being vacuumized, which is not limited herein.

The film stripping mechanism comprises the base 1, the feeding assembly 2, the stripping assembly 3 and the first material taking device 4, and further comprises a limiting assembly 5 and a buffer assembly 6, wherein the limiting assembly 5 is used for limiting the sliding range of the stripping platform 31, so that the moving range of the stripping platform 31 in the first direction is matched with the size of the conductive film in the first direction, and the conductive film is stripped conveniently; the buffer component 6 is used for decelerating the stripping platform 31 before the stripping platform 31 contacts the limiting component 5, so as to prevent the stripping platform 31 from suddenly stopping and damaging the stripping platform 31 due to impact.
