DETAILED DESCRIPTION

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, combined Figure 2 and Figure 3 A glass cutting and cracking device of the present invention includes a device body 1, a first support plate 2, a second support plate 3, a third support plate 4 and a cutting mechanism 5.

[0032] The device body 1 is provided with a first station, a second station, a third station, a fourth station and a fifth station in sequence, and the glass moves from the first station to the fifth station in sequence. The first support plate 2 carries the glass and moves it from the first station to the third station in sequence. The device body 1 is a work surface, which is horizontally and firmly set, and a plurality of guide rail sliding mechanisms are arranged on the surface to drive the movement of each support plate. In addition, a gantry beam is also assumed on the surface, and a two-axis driving mechanism is arranged on the gantry beam, and the two-axis driving mechanism drives the cutting mechanism 5 to translate and lift.

[0033] The first support plate 2 is arranged on the device body 1 and initially located at the first station, and the first support plate 2 moves along the moving direction of the glass. The second support plate 2 carries the glass and reciprocates between the first station and the third station.

[0034] The second support plate 3 is arranged on the device body 1 and initially located at the fifth station, and the second support plate 3 moves along the moving direction of the glass. The second support plate 3 carries the glass and reciprocates between the third station to the fifth station.

[0035] The third support plate 4 is disposed on the device body 1 and initially located at the fourth station. The end of the third support plate 4 facing the first station is configured as a raised end 41 , and the raised end 41 is raised upward relative to the device body 1 .

[0036] The cutting mechanism 5 is arranged on the device body 1 and above the second work station. The cutting mechanism 5 can be a laser cutting device or a diamond cutting knife device.

[0037] The process of cutting and splitting the glass in this embodiment is as follows: a) the first support plate 2 is initially at the first station, the fork tines of the mechanical fork arm hold the glass from the bottom of the glass, and then the glass is placed on the first support plate 2; b) the glass moves to the second station with the first support plate 2, and the cutting mechanism 5 horizontally cuts the glass in a direction perpendicular to the moving direction of the glass and forms a scratch on the glass; c) the glass moves to the third station with the first support plate 2, and the second support plate 3 also moves from the fifth station to the third station at this time, and the bottom of the glass is supported by the first support plate 2 and the second support plate 3 at the same time; d) the glass moves to the fourth station with the second support plate 3, and the tilted end 41 of the third support plate 4 is just below the scratch on the glass. When the tilted end 41 is aligned with the scratch and tilted at a certain angle, the scratch position on the lower surface of the glass will be subjected to the upward pushing force of the tilted end 41, so that the glass breaks into two petals along the scratch under the action of its own weight; e) the glass with two petals moves to the fifth station with the second support plate 3.

[0038] exist Figure 7 In the preferred embodiment shown, a top plate 6 is also included.

[0039] In this embodiment, the cutting mechanism 5 is provided with a diamond as a cutter. The two-axis driving mechanism drives the cutting mechanism 5 to first descend so that the cutter contacts the glass surface, and then the two-axis driving mechanism drives the cutting mechanism 5 to translate, and the diamond cutter scratches the glass surface. However, by controlling the sliding cutting depth of the diamond cutter, the glass is not completely cut by the cutter, so that the glass is split into two front and rear petals along the scratch position after moving to the fourth station.

[0040] When the glass moves with the first support plate 2, in order to avoid damage caused by friction between the top plate 6 and the lower surface of the glass, the surface of the top plate 6 is initially lower than the surface of the first support plate 2. When the glass moves to the second station, the top plate 6 moves in the vertical direction of the glass surface and supports the lower surface of the glass, the cutting mechanism 5 descends and makes the cutter contact the upper surface of the glass, and the cutting mechanism 5 cuts the glass. Since the cutting mechanism 5 in this embodiment cuts the glass with a diamond cutter, it is necessary to set the top plate 6 on the device body 1 and be located at the second station. The function of the top plate 6 is to support the bottom of the glass when the cutter cuts the glass, so as to avoid the glass being suspended below when the cutter cuts the glass, thereby avoiding the situation where stress concentration on the surface of the glass causes the glass to break.

[0041] exist Figure 3 and Figure 4In a preferred embodiment shown in the figure, in order to further reduce the contact area between the first pallet 2 and the lower surface of the glass, first steps 21 are provided at both ends and the center of the first pallet 2. The first pallet 2 supports the glass through the first step 21. Adsorption holes can be provided on the first step 21, and the glass is adsorbed and fixed on the first step 21 by vacuum adsorption; in addition, the first step 21 located in the center of the first pallet 2 also serves as a positioning mark. When the glass is moved to the second station, the first step 21 located in the center of the first pallet 2 is aligned with the top plate 6, indicating that the glass has moved into place, guiding the cutting mechanism 5 to cut the glass along the straight line formed by the first step 21 and the top plate 6.

[0042] exist Figure 3 In a preferred embodiment shown, second steps 31 are provided at both ends and the center of the second support plate 3, and the second support plate 3 supports the glass through the second steps 31, and adsorption holes may also be provided on the second steps 31. The second step 31 located in the center of the second support plate 3 also serves as a positioning mark. When the glass moves to the third station, the first step 21 located in the center of the first support plate 2 is aligned with the second step 31 located in the center of the second support plate 3, guiding the first support plate 2 and the second support plate 3 to support the middle of the glass; when the glass moves to the fourth station, the first step 31 located in the center of the second support plate 3 is aligned with the tilted end 41, guiding the scratch to be aligned with the second step 31 and the tilted end 41 in a straight line.

[0043] exist Figure 3 In a preferred embodiment shown, when the first pallet 2 is located at the first station, the end of the first pallet 2 facing the third station does not exceed the top plate 6; when the first pallet 2 and the second pallet 3 are located at the third station, the ends of the first pallet 2 and the second pallet 3 facing the first station do not exceed the top plate 6. The lengths of the first pallet 2 and the second pallet 3 are preferably the same.

[0044] exist Figure 2 In a preferred embodiment shown, a plurality of first support plates 2 are arranged at intervals in the vertical direction of the glass moving direction, a plurality of second support plates 3 are arranged at intervals in the vertical direction of the glass moving direction, a plurality of third support plates 4 are arranged at intervals in the vertical direction of the glass moving direction, and a plurality of top plates 6 are arranged at intervals in the vertical direction of the glass moving direction; each top plate 6 is arranged between adjacent first support plates 2, each second support plate 3 is arranged between adjacent third support plates 4, each first support plate 2 is aligned with each third support plate 4 in the glass moving direction, and each top plate 6 is aligned with each second support plate 3 in the glass moving direction. Each support plate and top plate are arranged at intervals in the horizontal direction, and the support plates and top plates are arranged alternately to avoid mutual obstruction when the support plates move.

[0045] exist Figure 5In a preferred embodiment shown, a movable seat 22 and a ball 23 are also included. In this embodiment, the ball 23 disposed on the top of the movable seat 22 is used to lift the glass, so that the glass and the ball 23 form point contact and will not hinder the movement of the glass between processes, greatly reducing the risk of damage to the glass surface due to friction.

[0046] The first support plate 2 is provided with a through hole, and the movable seat 22 is arranged in the through hole and moves along the vertical direction of the surface of the first support plate 2 .

[0047] The ball bearing 23 is arranged on the end surface of the movable seat 22 facing the glass, and the ball bearing 23 moves synchronously with the movable seat 22 toward the glass, and the ball bearing 23 contacts the glass and rolls on the glass surface. In order to avoid frictional contact between the second support plate 3 and the lower surface of the glass when it moves to the bottom of the glass, after the first support plate 2 carrying the glass moves to the third station, the movable seat 22 is lifted and the glass is lifted up by the ball bearing 23, so that the lower surface of the glass is higher than the upper surface of the second support plate 3, the second support plate 3 moves to the bottom of the glass, and then the movable seat 22 descends to the lowest position to place the glass on the second support plate 3, and at the same time, the first support plate 2 is withdrawn from under the glass through the ball bearing 23.

[0048] In addition, notches can be opened on the outer edges of the two outermost first support plates 2 on the left and right sides and the front and rear end edges, and rollers are arranged in the notches, and the rollers can be translated by a telescopic mechanism; on the one hand, when the glass is located at the first workstation, the telescopic mechanism telescopes and adjusts the position of the rollers so that the rollers contact the outer contour edge of the glass, thereby positioning and adjusting the position of the glass; and when the glass moves, the rollers will block the side of the glass and roll on the side of the glass, so that the glass can be transported and moved in the assembly line.

[0049] exist Figure 6 In a preferred embodiment shown in the figure, in order to realize the tilting action of the tilting end 41, it also includes a slider 7, a first support leg 8, a second support leg 9 and

[0050] The slider 7 is arranged on the device body 1 and moves along the moving direction of the glass.

[0051] One end of the first leg 8 is hinged to the slider 7 and the other end is hinged to the lower surface of the third support plate 4 away from the tilted end 41 .

[0052] One end of the second support leg 9 is disposed on the device body 1 and the other end is hingedly connected to the lower surface of the tilted end 41 of the third support plate 4 .

[0053] When the above technical solution is adopted, the slider 7 moves toward the first workstation, and the end of the third support plate 4 away from the tilted end 41 is pulled down by the first support leg 8, so that the tilted end 41 is tilted and higher than the upper surface of the second support plate 3.

[0054] like Figure 8As shown, a glass cutting and splitting production line of the present invention includes a front section 10, a rear section 20 and a transfer section 30.

[0055] The front section 10 cuts the glass into two pieces.

[0056] The rear section 20 cuts one of the glass pieces into two pieces again. The front section 10 and the rear section 20 both use a glass cutting and splitting device according to any of the above embodiments, so a piece of glass can be divided into four pieces horizontally and vertically through two cutting and splitting operations by the front section 10 and the rear section 20.

[0057] The transfer section 30 transfers one of the glass leaves of the front section 10 to the rear section 20. The transfer section 30 will only transfer one of the glass leaves of the front section 10 at a time, and the glass leaf is the one near the fourth station.

[0058] exist Fig. 9 In a preferred embodiment shown, the transfer section 30 includes a platform 301 , a first base 302 , a second base 303 and a fourth pallet 304 .

[0059] The platform 301 is a supporting frame structure, and a guide rail sliding block mechanism is also provided on the platform 301 to drive the first base 302 to move.

[0060] The first base 302 is disposed on the platform 301 and reciprocates between the front section 10 and the rear section 20 .

[0061] The second base 303 is disposed on the first base 302 and is axially rotatable and vertically liftable relative to the first base 302 .

[0062] The fourth support plate 304 is disposed on the second base 303 and supports the glass. A plurality of fourth support plates 304 are alternately disposed between the plurality of second support plates 3 .

[0063] When the glass is transferred, after the fourth support plate 304 holds up a piece of glass, the second base 303 is lifted and rotated 90 degrees to ensure that the piece of glass is vertical from horizontal, and then the first base 302 moves from the end of the front section 10 to the beginning of the rear section 20. At this time, the second base 303 descends and places the piece of glass on the first support plate 2 of the rear section 20. Since the width of the glass that the fourth support plate 304 needs to hold is one piece of the original glass, the length of the fourth support plate 304 is relatively short, and the fourth support plate 304 can enter between the two first support plates 2 when it is placed in the horizontal direction.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
