[0032] The whole glass substrate is conveyed forward by a plurality of conveying belts 20 until the glass substrate is conveyed to the lower end position of the cutters 31, the glass substrate is fixed by the limiting of the inner edge support structure 40, and the front end of the glass is limited in the transverse position by the front correction structure 50 before cutting, and then the cutter 31 is lowered to start cutting.
[0033] In the existing glass cutting device with a belt type, the penetration force after cutting is easy to cause the glass to tilt, thereby damaging the cut glass by the cutter and affecting the imaging quality of the glass, therefore, the inner edge support structure 40 is arranged in the embodiment, when the glass moves to the lower end position of the cutter 31, the front end guide 43 is first lifted to preliminarily limit the conveyed glass, then the rear end guide 44 at the rear end is lifted to limit and fix the two sides of the glass, when the rear end guide 44 is lifted, the gap support 45 is lifted to tightly abut against the lower side of the glass, the gap support 45 is arranged below the cutting end, so that the cutter 31 can directly sink into the gap support 45, and the gap support 45 supports the glass, so that the glass can be in a relatively stable state when being cut.
[0034] Since a glass substrate is generally cut into multiple pieces, and different requirements of glass substrates require different sizes, the transverse frame 41 of the embodiment comprises mounting buckles 411 locked inside the conveying machine table 10, two mounting buckles 411 are connected with a transverse mounting plate 412, the transverse mounting plate 412 is movably provided with a plurality of adjusters 413, the adjusters 413 divide the transverse mounting plate 412 into a plurality of areas, by setting a plurality of adjusters 413 at the lower end position of the conveying belt 20, one adjuster 413 can correspond to one glass cutting area, so that each glass cutting area can receive the corresponding effect.
[0035] The above-mentioned different requirements of glass substrates require different sizes, so the position of the adjuster 413 is not fixed, in order to adapt to the size required by different glass substrates, the transverse mounting plate 412 of the embodiment is provided with a chute, the chute is provided with a rib groove, the adjuster 413 comprises an adjusting frame 4131 slidably arranged in the chute, the adjusting frame 4131 is provided with a through hole in the middle, and a abutting pin 4132 is arranged through the through hole and locked at the bottom of the chute, the adjuster 413 and the transverse mounting plate 412 are slidably arranged, so that the adjuster 413 can be moved to the required position, and in order to avoid the phenomenon of running position of the adjuster 413 after moving in the cutting process, the adjuster 413 after moving is also fixed through the abutting pin 4132, so as to ensure that the adjuster 413 is not easy to displace during cutting.
[0036] Since the front end guide 43 and the rear end guide 44 are lifted separately, they cannot be installed on the same lifting structure, so although they are installed on the same lifting table 42, the lifting table 42 comprises an upper lifting seat 421 and a lower lifting seat 422 fixed on the adjusting frame 4131, the upper lifting seat 421 and the lower lifting seat 422 are driven by different motors, the upper lifting seat 421 is connected with the front end guide 43, the lower lifting seat 422 is connected with the rear end guide 44, the front end guide 43 and the rear end guide 44 are respectively installed on the upper lifting seat 421 and the lower lifting seat 422, so that the lifting of the upper lifting seat 421 does not affect the lower lifting seat 422, and the stability of the two is maintained.
[0037] The front end guide 43 and the rear end guide 44 are similar in structure, specifically, the front end guide 43 comprises two spaced front L-shaped limiting buckles 431 arranged on the upper lifting seat 421, and a front damping strip 432 is connected to the two front L-shaped limiting buckles 431; the rear end guide 44 comprises two spaced rear L-shaped limiting buckles 441 arranged on the lower lifting seat 422, and a rear damping strip 442 is connected to the two rear L-shaped limiting buckles 441; the inner sides of the two rear L-shaped limiting buckles 441 are connected to a gap support 45, so that the glass substrate to be cut can be fixed at both ends by the four L-shaped limiting buckles; it is emphasized that the two front L-shaped limiting buckles 431 and the two rear L-shaped limiting buckles 441 are arranged on the two sides of the cutting line, so they do not hinder the cutting action.
[0038] The gap support 45 needs to give way to the cutter 31 when supporting the glass, so as to ensure the smooth cutting action, therefore, the gap support 45 comprises a U-shaped groove 451 connected to the rear end guide 44, the opening of the U-shaped groove 451 is opposite to the position of the cutter 31, the top of the two ends of the opening of the U-shaped groove 451 is locked by an inner top strip 452, the elastic member 46 is located at the middle position of the lower part of the U-shaped groove 451; the gap support 45 is a structure with a middle groove, so that the cutter can sink into the U-shaped opening of the gap support 45 after cutting is completed; in order to stably contact with the glass, the two ends of the top of the gap support 45 need to be in flexible contact with the glass by the flexible inner top strip 452; and since the span of the entire U-shaped groove 451 is too large and the other end of the U-shaped groove 451 cannot be attached to the front end guide 43, the elastic member 46 is arranged at the middle position of the bottom end of the U-shaped groove 451, so that the support force of the front and rear ends of the U-shaped groove 451 is more uniform through the support of the elastic member 46.
[0039] During the cutting of the glass, all the conveying belts 20 are actually in a state of vibration; although the glass being cut is relatively stable due to the fixing of the front end guide 43 and the rear end guide 44, the glass waiting at the front end is prone to vibration, so that the originally calibrated position deviates slightly, and once the deviation occurs, the cutting area is prone to unevenness during the cutting process, so that the glass substrate becomes waste; therefore, the front correction structure 50 is arranged on the basis of the inner edge support structure 40, when the rear end guide 44 is raised into position, the lower fitting member 47 and the middle fitting member 53 are in the same straight line at this time, the position of the limiting frame 51 is fixed before cutting through the cooperation of the lower fitting member 47 and the middle fitting member 53, so that the glass substrate waiting for processing in the limiting frame 51 is fixed; even if the conveying belt 20 vibrates, the position of the front end glass substrate is not affected, so as to improve the cutting precision of the glass from another aspect.
[0040] In the process of limiting the front end of the glass, the actual transmission path of the glass is normal, and deviation does not occur. Only the nearest glass will deviate slightly during cutting. Therefore, the limiting frame 51 of the embodiment comprises a side limiting plate 511 arranged at the edge of the outermost conveying belt 20. The side limiting plate 511 extends downward and is provided with an L-shaped corner bracket 512. The L-shaped corner bracket 512 is slidingly connected to the top of the middle bracket 52. The limiting frame 51 is arranged only on the front end of the glass in the cutting position. The side limiting plate 511 has a certain slidable distance, so that it can better adapt to the glass when initially contacting the glass. The L-shaped corner bracket 512 can slightly slide on the middle bracket 52, without causing hard obstruction to the glass.
[0041] In order to facilitate the cooperation between the middle cooperation part 53 and the lower cooperation part 47, the middle cooperation part 53 of the embodiment is a tubular cavity pipe. The opening of one end of the tubular cavity pipe close to the lower cooperation part 47 is larger than the opening of the side close to the middle bracket 52. The middle cooperation part 53 is arranged as a tubular cavity pipe similar to a horn, thereby facilitating the contact and cooperation of the lower cooperation part 47. The lower cooperation part 47 specifically comprises a push rod motor 471 fixed outside the lower lifting seat 422. A pair of docking cones 472 are connected to the output end of the push rod motor 471. The docking cones 472 are clamped in the tubular cavity pipe after being pushed out, and only displace after the lower lifting seat 422 is lifted to the corresponding height. The structure for cooperating with the tubular cavity pipe is the docking cone 472. After cooperation, the fit is tight. The docking cone 472 is not easy to disengage and jump after the later period.
[0042] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
