Detailed ways

The preferred embodiments of the present invention will be further elaborated below with reference to the accompanying drawings of the present specification.

Referring to FIG. 2, FIG. 2 is a schematic diagram of the working principle of the glue sticking device of the present invention. The present invention provides an adhesive sticking device 10 , which implements sticking by means of laterally feeding the sticking paper 500 , that is, the conveying direction of the sticking paper 500 (indicated by the arrow M50 in the figure) and the movement of the substrate 20 The directions (that is, indicated by the arrow M20 in the figure) are parallel. Specifically, the single tape 50 is rectangular and has a set length L and width W. The cutting of a single tape 50 extends along the width direction of the tape 500 . In this gluing method, the width W of a single adhesive tape 50 is adjusted by adjusting the width of the adhesive-carrying surface 111 on the rubber roller 11 .

Referring to FIG. 3 in conjunction, FIG. 3 is a schematic structural diagram of a preferred embodiment of the glue sticking device of the present invention. The glue sticking device 10 generally includes: a rubber pulling roller 11 , a ratchet and pawl combination mechanism 13 , a vacuum communication mechanism 15 , a cutter mechanism 17 , a glue sticking platform 19 and an air cylinder 18 .

The gluing roller 11 is mounted on the gluing platform 19 through sliding or rolling support (not shown in the figure), such as bearings. The gluing platform 19 is driven by the air cylinder 18 and can drive the gluing roller 11 to move linearly between the initial position P1 and the gluing position P2. The outer contour of the rubber pulling roller 11 is a cylinder, and the outer surface thereof is provided with a plurality of glue-carrying surfaces 111 , which can adsorb the glue paper 500 thereon. The rubber pulling roller 11 can be driven by the tension of the adhesive paper 500 (ie, the adsorption force between the adhesive paper 500 and the adhesive-carrying surface 111 ) to rotate. In addition, the rubber-pulling roller 11 also functions as a rubber-applying roller, that is, it can transfer a single adhesive paper 50 to the substrate 20 .

When the gluing platform 19 is driven by the air cylinder 18 to drive the gluing roller 11 to move from the initial position P1 to the gluing position P2 (that is, move straight down), corresponding to the gluing process, the gluing roller 11 A single adhesive tape 50 on the substrate can be attached to the base material 20 correspondingly.

Conversely, when the gluing platform 19 is driven by the air cylinder 18 to drive the gluing roller 11 to move from the gluing position P2 to the initial position P1 (ie, move straight up), corresponding to the gluing process, the ratchet pawl The combination mechanism 13 restricts the rubber pulling roller 11 to rotate by a set angle in one direction, that is, the adhesive tape 500 is pulled by the rubber pulling roller 11 and walks the set width W of a single adhesive tape 50 .

The rubber-pulling roller 11 absorbs the adhesive paper 500 in a vacuum manner. Specifically, each adhesive-carrying surface 111 is provided with a plurality of holes, which can absorb the adhesive paper 500 and a single adhesive paper 50 by using negative pressure. The length dimension of each adhesive-carrying surface 111 is approximately equal to the set length L of a single adhesive paper 50 . The width dimension of each adhesive-carrying surface 111 matches the set width W of a single adhesive paper 50 .

Specifically, the ratchet and pawl combination mechanism 13 and the vacuum communication mechanism 15 are respectively fixed and installed on both ends of the rubber pulling roller 11 . The vacuum communication mechanism 15 cooperates with the rubber pulling roller 11 to provide a vacuum for adsorbing the adhesive tape 500 and for breaking the vacuum for a single adhesive tape 50 .

The ratchet and pawl combination mechanism 13 converts the linear movement of the rubber-pulling roller 11 into a set angle of unidirectional rotation of the rubber-pulling roller 11 , and the set angle corresponds to a central angle corresponding to a polygonal surface of the rubber-pulling roller 11 ( 45 degrees in FIG. 2 and 36 degrees in FIG. 3 ), so that the adhesive tape 500 can be transported parallel to the moving direction of the substrate 20 , and at least one polygonal surface can absorb a single adhesive tape 50 .

The single tape 50 mentioned here refers to the situation where the tape 500 can be pasted on the substrate 20 after being cut by the cutter unit 106 according to the set requirements. Specifically, each polygonal surface of the rubber-pulling roller 11 includes a glue-carrying surface 111 and two spaced grooves 113 respectively located on both sides of the glue-carrying surface 111 .

The adhesive paper 500 is first transported downward to a position close to the upper surface of the base material 20 , then transported horizontally, and then transported around and adsorbed on the surface of the rubber pulling roller 11 . This structure can ensure that the rubber-pulling roller 11 exerts a sufficiently large and uniform pulling force on the adhesive paper 500 to achieve efficient and stable pulling of the adhesive paper 500 .

The cutter mechanism 17 includes a cutter 171 matched with the glue roller 11 and a cutter and glue removing combination 173 matched with the cutter 171 . The cutter glue removing assembly 173 is used to remove the glue left on the cutter 171 . The cutter 171 can cut the adhesive paper 500 into a single adhesive paper 50 along the length direction of the rubber pulling roller 11 . Specifically, the cutter 171 can extend into the interval groove 113 to cut the adhesive paper 500 into a single adhesive paper 50 along the length direction of the rubber pulling roller 11 .

The gluing platform 19 includes a vertical plate for installing the gluing roller 11 . The vertical plate is driven by the air cylinder 18 and can move up and down. Wherein, when the gluing platform 19 is located at the upper position, it corresponds to the initial position P1 of the rubber pulling roller; when the gluing platform 19 is located at the lower position, it corresponds to the gluing position P2 of the rubber pulling roller. It will be appreciated that in other embodiments, the cylinder 18 may be implemented using other drive elements such as a motor.

It is worth mentioning that, in this embodiment, the rubber-pulling roller 11 absorbs the adhesive paper 500 and a single adhesive paper 50 in a vacuum manner. The control range for breaking the vacuum of the rubber-stretching roller 11 corresponds to a polygonal surface of the rubber-stripping roller 11 to release a single adhesive tape 50 . In other embodiments, the rubber-pulling roller 11 can adsorb the adhesive paper 500 in an electrostatic manner. Similarly, the control range for breaking static electricity of the rubber-stretching roller 11 corresponds to a polygonal surface of the rubber-stripping roller 11 to release a single adhesive paper 50 . In this embodiment, the outer contour of the rubber-pulling roller 11 is a polygonal cylinder; correspondingly, the rubber-carrying surface 111 is a plane. In other embodiments, the outer contour of the rubber-pulling roller 11 may be a cylinder; correspondingly, the rubber-carrying surface 111 is a circular arc surface.

The fixed pawl 137 is fixed on other structures other than the gluing platform 19 and will not move up and down with the gluing platform 17 . When the glue application platform 19 drives the rubber puller 11 to move from the initial position P1 to the glue application position P2, and then returns to the initial position P1 from the glue application position P2, the ratchet and pawl combination mechanism 13 restricts the rubber pulling roller 11 in one direction Rotate a set angle.
