According to research, in the related technology, in the field of glass substrate manufacturing and transportation, automatic packaging equipment is a key link for ensuring product cleanliness and preventing physical damage. The packaging process needs to meet two core requirements, namely, the packaging film needs to have high tensile strength and toughness to bear tensile deformation without cracking during mechanical cutting, and the packaging film needs to be subjected to antistatic treatment to prevent dust from being adsorbed by static electricity or a substrate circuit from being damaged.
In the related art, the width of the packaging film is generally set to coincide with the width of the glass substrate, and the substrate is wrapped by mechanical winding. And after winding, manually performing edge sealing operation. However, manual sealing is susceptible to handling skill, resulting in uneven butt joint of the trailing end of the packaging film with the glass substrate. This causes dust or foreign matter to invade the inner wall of the packaging film and contaminate the surface of the glass substrate. Even if the edge sealing is neat, the tail end of the packaging film with the same width can increase the technical problem of operation difficulty due to inconvenient searching of the seal during disassembly.
Therefore, how to solve the problem of irregular butt joint between the tail end of the packaging film and the glass substrate is a technical problem in the art.

Referring to fig. 3, a cutting bracket 5 is vertically arranged above the adjusting bracket 21 and spans the upper area of the packaging film 3, the cutting bracket 5 is fixed at the end of the cutting platform 4, and the bottom of the cutting platform 4 is fixed on the inner wall of the adjusting bracket 21 through a cross beam. The cutting bracket 5 is vertically arranged, and the adjusting bracket 21 is horizontally arranged, so that the cutting bracket 5 is relatively vertical to the adjusting bracket 21. The width of the cutting bracket 5 is larger than the width of the packaging film 3. The cutting device 6 is arranged on the cutting bracket 5 in a lifting manner through linear driving 66, the number of the linear driving 66 is two, and the first positioning block 61 and the second positioning block 62 are respectively arranged at the movable ends of the two linear driving 66. Further, the linear drive 66 is a ball screw driven by a servo motor to control the lifting accuracy of the first positioning block 61 and the second positioning block 62.
Referring to fig. 3, the cutting device 6 includes a first positioning block 61 and a second positioning block 62, which are disposed in parallel, and are located above the positioning groove 40, wherein a bevel 65 is disposed on a side of the first positioning block 61 near the positioning groove 40, and further, the inclination angle of the bevel 65 is 15 ° so as to slow down the initial extrusion force of the first positioning block 61 on the packaging film 3.

With continued reference to fig. 3, in order to improve the stability of the lifting movement of the first positioning block 61 and the second positioning block 62, the side wall of the cutting bracket 5 is vertically provided with a guide groove 50, and two ends of the first positioning block 61 and the second positioning block 62 are slidably disposed in the guide groove 50.

the first positioning block 61 and the second positioning block 62 are arranged in parallel relatively and are arranged above the packaging film 3 in a lifting manner;
A cutter 63 hinged to a side wall of the first positioning block 61, the side wall abutting against the second positioning block 62 at an initial position;
the adhesive strips 64 are respectively detachably embedded in the two side walls of the positioning groove 40;
Wherein, the first positioning block 61 and the second positioning block 62 move downwards synchronously to squeeze the packaging film 3 to deform and be embedded into the positioning groove 40, and the bottom wall of the packaging film 3 is adhered and fixed with the two adhesive tapes 64;
When the first positioning block 61 continues to move downward, the first positioning block 61 presses the packaging film 3 to be stretched in the length direction and contracted and deformed in the width direction;
The cutter 63 is turned over outward with the hinge point as an axis to cut the packaging film 3, and the width of the cut-off packaging film 3 is smaller than the width of the other parts.
At least one embodiment provides a packaging process of an automatic packaging apparatus, the packaging process comprising:
The packaging film 3 is unreeled outwards through the unreeling roller 1, and when the packaging film 3 passes through the adjusting bracket 21 arranged on the frame 2, the guide rollers 22 positioned at the two ends of the adjusting bracket 21 can tension the packaging film 3 to prevent the packaging film from deviating;
when the linear drive 66 arranged on the cutting bracket 5 drives the first positioning block 61 and the second positioning block 62 to synchronously move downwards, the bottom of the linear drive 66 extrudes the packaging film 3 to deform and be embedded into the positioning groove 40, and the bottom wall of the packaging film 3 is attached and fixed with the two adhesive tapes 64;
When the first positioning block 61 continues to move downward, the first positioning block 61 presses the packaging film 3 to be stretched in the length direction and contracted and deformed in the width direction;
after the cutting knife 63 is separated from the limit constraint of the second positioning block 62, the hinge point is taken as the axis to turn outwards so as to cut off the packaging film 3.
The working process and principle of the automatic packaging equipment for the glass substrate are as follows:
Film unreeling and transporting, namely releasing the packaging film 3 from the unreeling roller 1, tensioning the packaging film by the guide roller 22 and guiding the packaging film to the cutting station.
Cutting preparation and film fixing when the wrapping film 3 is wrapped around the glass substrate and the wrapping film 3 needs to be cut off, the linear drive 66 drives the first positioning block 61 and the second positioning block 62 to move downwards synchronously. The bottom of the first positioning block 61 and the second positioning block 62 squeeze the packaging film 3 to elastically deform and are embedded into the positioning groove 40. At this time, the bottom wall of the packaging film 3 is attached to the adhesive tapes 64 on both sides, and is fixed by adhesion.
The first positioning block 61 continues to move downward, and the film is extruded to be stretched in the longitudinal direction and contracted and deformed in the width direction. Due to the poisson ratio effect of the film, the width of the fracture area is contracted, and the profile forms a narrow notch. The inclined plane 65 is designed to slow down the extrusion force and avoid rupture of the membrane material.
Automatic cutting and tail end processing, namely when the first positioning block 61 moves down to the position that the hinge axis of the cutting knife 63 is lower than the limit of the second positioning block 62, the cutting knife 63 is out of constraint. The torsion spring drives the cutter 63 to turn over outwards with the hinge point as the axis, and the cutting edge of the cutter 63 cuts off the packaging film 3. After cutting, the tail end of the packaging film 3 is adhesively secured by the adhesive strip 64 without risk of loosening.
