Description

Technical Field

[0001] The utility model relates to the technical field of display screen production, in particular to a peeling and attaching mechanism for an easy-to-tear adhesive tape. Background Art

[0002] The production of LCD screens involves many processes, among which semi-finished products generally need to be dispatched in different production workshops. In order to better protect the semi-finished products from damage or contamination during transportation and dispatch, a protective film is generally affixed to one side of the semi-finished products after they are produced. At the same time, it is also necessary to attach tape to the side of the protective film to facilitate the peeling of the protective film in subsequent processes.

[0003] In the actual assembly and production process of LCD screens, there are two ways to attach tape to the protective film: manual attachment and robot attachment. Manual attachment is to pick up the product from the conveyor belt, attach the tape, and then put it back on the conveyor belt. This can easily cause the product to be placed off-center on the conveyor belt. At the same time, it can easily cause secondary contamination to the cleaned product during the picking process. Therefore, the success rate of manual attachment is relatively high, but the efficiency of attachment is too low. The current automated attachment by robots will increase the cost of product production and also require space, reducing the utilization rate of the space. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4In this embodiment, a peeling and attaching mechanism for an easy-to-tear adhesive tape includes a mounting plate 9 and a moving mechanism, wherein a suction head 8 is installed at the moving end of the moving mechanism, and a reel 10, a reel 19, a plurality of transmission rollers 14, a support plate 16, a driving roller 13 and a clamping roller 15 located below the driving roller 13 are installed on the front of the mounting plate 9, wherein the bottom of the protruding end of the support plate 16 is tilted downward with a slope, and the driving shaft end of the driving roller 13 is connected to the reel 19 through a belt device, and a convex cylinder 20 is fixed on the outer side of the reel 19, and a limiting disk 11 is fixed on the outer side of the convex cylinder 20 and a clamping assembly is provided.

[0018] In the above structure, one end of the tape is clamped and fixed on the convex cylinder by the clamping assembly, and then the tape is conveyed by the cooperation of the pressure roller, the driving roller and the transmission roller, and the reel is driven to rotate, so that the tape can be recovered to the convex cylinder, and at the same time, the tape with the easy-tear label can be conveyed to the pallet, and the easy-tear label is adsorbed and peeled off by the adsorption head driven by the moving mechanism, and then transferred to the protective film to complete the attachment.

[0019] like Figure 4 The clamping assembly includes two oppositely distributed grooves opened on the outside of the convex cylinder 20, the grooves are semicircular, and a U-shaped clamping column 12 passing through the limit plate 11 is clamped between the two grooves. The U-shaped clamping column 12 is made of steel or titanium alloy, and is clamped and embedded in the grooves. The tape is wrapped around the convex cylinder, and then the U-shaped clamping column is opened and aligned with the groove, and the tape is located on the inner side of the U-shaped clamping column. One end of the tape is fixed on the convex cylinder through the toughness rebound of the U-shaped clamping column to complete the clamping positioning.

[0020] like Figure 3 The top of the support plate 16 is provided with three shallow grooves arranged at equal distances, a pair of waist holes 17 are provided inside the shallow grooves, and two guide plates 18 are slidably connected between the three shallow grooves, and the guide plates 18 are fixed by bolts passing through the waist holes 17. During the conveying process of the tape, the guide plates can be moved in the limit grooves and positioned by bolts passing through the waist holes, so that the tape and the easy-tear sticker can be guided according to the width adjustment position to avoid conveying deviation.

[0021] like Figure 2 The moving mechanism includes a lateral moving device 1 installed near the mounting plate 9, a longitudinal moving device 2 is installed at the moving end of the lateral moving device 1, a lifting device 4 is installed at the moving end of the longitudinal moving device 2, and the adsorption head 8 is installed at the moving end of the lifting device 4. The adsorption head is driven to move above the easy-to-tear sticker by the lateral moving device and the longitudinal moving device, and then the lifting device drives the adsorption head to adsorb the easy-to-tear sticker, and then the lifting device is lifted and the longitudinal moving device is pushed forward, so that the easy-to-tear sticker is peeled off from the tape and the peeling operation is completed.

[0022] The movable end of the lifting device 4 is equipped with a rotating cylinder 5 and a sensing block 7. The sensing block 7 is concave. A guide piece 6 that shuttles through the inner side of the sensing block 7 is fixed on the outer side above the rotating shaft of the rotating cylinder 5. A V-shaped opening is provided on one side of the guide piece 6. The suction head 8 is installed at the bottom end of the rotating shaft of the rotating cylinder 5. After the easy-to-tear sticker is peeled off, the easy-to-tear sticker is driven to move to a suitable position by the lateral moving device. The direction of the sticky surface of the easy-to-tear sticker can be adjusted by the rotation of the rotating cylinder. At the same time, the guide piece will also rotate. Through the cooperation of the V-shaped opening and the sensing block, the easy-to-tear sticker can be driven by the suction head to rotate forward and flip, and rotate to the same angle, so that adhesion can be completed on both sides of the upper surface of the protective film. By attaching two easy-to-tear stickers, it is convenient to tear off the protective film later.

[0023] The working principle of the above embodiment is:

[0024] First, the position of the guide plate in the shallow groove is adjusted according to the width of the conveying tape and the easy-tear label, so that the guide plate can be used to guide the conveying according to the easy-tear labels of different widths. Then, one end of the tape on the unwinding disk is wound around the transmission roller, the support plate and the driving roller in sequence, and the tape is wound around the convex cylinder. Then, a U-shaped clamping column is added to the groove to clamp and position the tape. Then, the pressing roller is pressed up to cooperate with the driving roller to drive the winding shaft to rotate, so that the tape can be conveyed and wound around the convex cylinder for collection. When the tape drives the easy-tear label to be located at When the plate is at the leftmost end of the plate surface, the lateral moving device, the longitudinal moving device and the lifting device drive the adsorption head to move to the top of the non-adhesive side of the easy-tear label and adsorb it. The lifting device lifts it up and the longitudinal moving device pushes it forward, thereby completing the peeling action to peel off the easy-tear label. The easy-tear label is driven to be above the protective film by the lateral moving device, and the adsorption head is driven to rotate forward and flip through the rotating cylinder. Through the cooperation of the sensing block and the guide plate, the adsorption head can be driven to rotate in both directions at the same angle, thereby completing the attachment of the easy-tear label to the protective film.
