Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal glass processing, in particular to a liquid crystal glass cutting and cracking device. Background Art

[0002] Liquid crystal glass, also known as electrically controlled liquid crystal glass or dimming glass, is a high-tech optoelectronic glass product made by sandwiching a liquid crystal film under high temperature and high pressure. Users can control the alignment of the liquid crystal molecules by switching on or off an electric current, ultimately achieving the ultimate goal of controlling the transparency and opacity of the glass. The liquid crystal film in the middle layer serves as the functional material for dimming glass. The principle of application is that when the current is on, the liquid crystal molecules align in a straight line, making the liquid crystal glass translucent and transparent. When the power is off, the liquid crystal molecules scatter, making the film translucent but opaque.

[0003] Prior art has disclosed a Chinese invention patent for crack separation equipment and methods (publication number: CN102643018B). The equipment and methods include a vibration platform for securing at least one liquid crystal panel to be cracked and vibrating the panel, causing the glass substrate of the panel to break along a cutting crack. Based on the principles of vibration, the equipment and methods of the present invention ensure that the cracks on the glass substrate forming the cracks extend fully along the thickness of the glass substrate, thereby achieving crack separation. The separation process is easily controllable and does not contaminate or damage the liquid crystal panel.

[0004] Although the above-mentioned prior art uses the arrangement of structures such as high-frequency vibration motors and, according to the principle of vibration, enables the cutting cracks on the glass substrate with cutting cracks to fully extend in the thickness direction of the glass substrate, thereby achieving the effect of crack separation, the separation process is easy to control and will not cause pollution or damage to the liquid crystal panel. However, when cutting and cracking the liquid crystal glass, the liquid crystal glass is not pretreated in advance, which may cause the cutting knife to contact with hard objects on the surface of the liquid crystal glass during the cutting process of the liquid crystal glass, resulting in damage to the cutting knife and damage to the liquid crystal glass when the cutting knife is pressed against the hard object. As a result, not only the cutting knife cannot cut the liquid crystal glass, but also the liquid crystal glass cannot be processed subsequently, resulting in waste of liquid crystal glass.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a liquid crystal glass cutting and splitting device, comprising a conveying unit, a cutting mechanism installed on one side of the conveying unit, and a splitting mechanism installed on the surface of the conveying unit;

[0010] As a further optimization, the cutting mechanism also includes a servo motor fixedly connected to one side of the mounting plate and the output end is fixedly connected to the threaded rod. One side of the supporting plate is rotatably connected to a clip plate corresponding to the soft baffle and the cleaning plate through a torsion spring, and the clip plate corresponds to the supporting plate.

[0011] As a further optimization, the pushing mechanism includes a driving motor fixedly connected to the lower surface of the supporting plate, the output end of the driving motor is fixedly connected to a screw rod, the surface of the screw rod is threadedly connected to an extrusion plate slidingly connected to the supporting plate, and the surface of the extrusion plate is slidingly sleeved with a limit plate fixedly connected to the supporting plate.

The high-frequency vibration motor is started, and according to the principle of vibration, the cutting cracks on the glass substrate with cutting cracks are fully extended in the thickness direction of the glass substrate, thereby achieving the effect of splitting and completing the processing of the liquid crystal glass. In addition, through the movement of the conveying unit, the debris generated after the liquid crystal glass is split is driven to move synchronously, thereby preventing the debris from affecting the subsequent liquid crystal glass processing.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, a liquid crystal glass cutting and splitting device includes a conveying unit 1, a cutting mechanism is installed on one side of the conveying unit 1, and a splitting mechanism is installed on the surface of the conveying unit 1. The cutting mechanism includes a support frame 2 fixedly connected to one side of the conveying unit 1, and the upper surface of the support frame 2 is fixedly connected to a carrying plate 3 corresponding to the conveying unit 1. The liquid crystal glass is placed on the carrying plate 3 so that the extrusion plate 19 is in contact with one side of the liquid crystal glass. The lower surface of the carrying plate 3 is installed with a pushing mechanism, and the pushing mechanism includes a driving motor 17 fixedly connected to the lower surface of the carrying plate 3. The output end of the driving motor 17 is fixedly connected to a screw rod 18, and the surface of the screw rod 18 is threadedly connected to the extrusion plate 19 slidably connected to the carrying plate 3. The surface of the extrusion plate 19 is slidably sleeved with a limit plate 20 fixedly connected to the carrying plate 3. The driving motor 17 is started, so that its output end drives the screw rod 18 to rotate, thereby moving the extrusion plate 19 and driving the liquid crystal glass to move. The moving position of the liquid crystal glass is adjusted according to the required cutting width.

[0028] The upper surface of the carrying plate 3 is fixedly connected to the mounting plate 4, and the surface of the mounting plate 4 is fixedly connected to the first electric push rod 5. The output end of the first electric push rod 5 is fixedly connected to the abutting plate 6 corresponding to the carrying plate 3. Both sides of the inner top wall of the abutting plate 6 are rotatably connected to the pushing plate 7 through a pin shaft. One side of the pushing plate 7 is fixedly connected to a reset spring 30 fixedly connected to the abutting plate 6. Based on the elastic force of the reset spring 30, the pushing plate 7 can automatically reset after use, thereby facilitating the subsequent use of the pushing plate 7 and the cleaning plate 8;

[0029] One end of the two pushing plates 7 is connected to the cleaning plate 8 corresponding to the supporting plate 3 through a pin shaft. Both sides of the lower surface of the cleaning plate 8 are fixedly connected with elastic pads 11. Both sides of the lower surface of the elastic pad 11 are installed with guide wheels 12 corresponding to the supporting plate 3. Through the mutual cooperation of the elastic pad 11 and the guide wheel 12, when the cleaning plate 8 moves, the guide wheel 12 guides the cleaning plate 8, thereby making the movement of the cleaning plate 8 more stable;

[0030] The cutting mechanism also includes a holding spring 9 fixedly connected to the inside of the holding plate 6 in a path array. One end of several holding springs 9 is fixedly connected to a soft baffle 10 corresponding to the carrier plate 3. After the liquid crystal glass stops moving, the first electric push rod 5 is started, and its output end drives the holding plate 6 to move downward, so that the soft baffle 10 fits the liquid crystal glass, and the liquid crystal glass is held in place. The elastic force of the holding spring 9 prevents the soft baffle 10 from applying excessive force to the liquid crystal glass, which may cause damage to the liquid crystal glass.

[0031] During the movement of the pressing plate 6, the pushing plate 7 is synchronously driven to move, so that the cleaning plate 8 is in contact with the liquid crystal glass. Based on the continuous movement of the pressing plate 6, the pushing plate 7 drives the cleaning plate 8 to slide on the surface of the liquid crystal glass to clean its surface, thereby preventing subsequent hard objects on the liquid crystal glass from affecting the cutting blade 16.

[0032] The cutting mechanism also includes a guide plate 13 fixedly connected to one side of the abutment plate 6. A threaded rod 14 corresponding to the abutment plate 6 is rotatably connected to the interior of the guide plate 13 via a bearing seat. A movable plate 15 is threadedly connected to the surface of the threaded rod 14. A cutting blade 16 is installed inside the movable plate 15 and the supporting plate 3. The servo motor 21 is started to drive the threaded rod 14 to rotate, so that the movable plate 15 drives the cutting blade 16 to slide on the upper and lower surfaces of the liquid crystal glass to cut the liquid crystal glass.

[0033] One of the cutting blades 16 is slidably connected to the carrying plate 3, and the other cutting blade 16 is fixedly connected to the movable plate 15. The two cutting blades 16 are fixedly connected. The cutting mechanism also includes a servo motor 21 fixedly connected to one side of the mounting plate 4 and whose output end is fixedly connected to the threaded rod 14. One side of the carrying plate 3 is rotatably connected to a clamping plate 22 corresponding to the soft baffle 10 and the cleaning plate 8 through a torsion spring. The clamping plate 22 corresponds to the carrying plate 3.

[0034] The splitting mechanism includes a mounting frame 23 fixedly connected to the surface of the conveying unit 1, a high-frequency vibration motor 24 fixedly connected to the surface of the mounting frame 23, an output end of the high-frequency vibration motor 24 fixedly connected to a vibration rod 25 corresponding to the conveying unit 1, and a vibration plate 26 fixedly connected to the surface of the vibration rod 25. The splitting mechanism also includes a support rod 27 fixedly connected to the upper surface of the mounting frame 23, a second electric push rod 28 fixedly connected to one side of the support rod 27, and an output end of the second electric push rod 28 fixedly connected to a fixed plate 29 corresponding to the vibration plate 26. After the liquid crystal glass is cut, based on the movement of the squeezing plate 19, the liquid crystal glass moves to the surface of the conveying unit 1, so that the conveying unit 1 drives the liquid crystal glass to move below the fixed plate 29;

[0035] The second electric push rod 28 is started, and its output end drives the fixed plate 29 to move, thereby fixing the liquid crystal glass, so that the liquid crystal glass is fixed between the fixed plate 29 and the vibration plate 26. Then, the high-frequency vibration motor 24 is started, and its output end drives the vibration rod 25 to vibrate, so that the vibration force of the vibration plate 26 is transmitted to the liquid crystal glass. According to the principle of vibration, the cutting crack on the glass substrate with the cutting crack is fully extended in the thickness direction of the glass substrate, thereby achieving the effect of crack separation, and completing the processing of the liquid crystal glass;

[0036] Both sides of the upper surface of the conveying unit 1 are fixedly connected to limit rods corresponding to the fixed plate 29 in a path array. Based on the setting of the limit rods, the liquid crystal glass is prevented from falling on the conveying unit 1;

[0037] The movement of the conveying unit 1 drives the debris generated after the liquid crystal glass breaks to move synchronously, thereby preventing the debris from affecting subsequent liquid crystal glass processing.

[0038] Specifically, when the liquid crystal glass cutting and splitting device is in use: the liquid crystal glass is placed on the carrier plate 3, so that the squeezing plate 19 is in contact with one side of the liquid crystal glass, the driving motor 17 is started, and its output end drives the screw 18 to rotate, thereby moving the squeezing plate 19 and the liquid crystal glass. The moving position of the liquid crystal glass is adjusted according to the required cutting width. After the liquid crystal glass stops moving, the first electric push rod 5 is started, and its output end drives the clamping plate 6 to move downward, so that the soft baffle 10 is in contact with the liquid crystal glass, and the liquid crystal glass is clamped and limited. The elastic force of the clamping spring 9 prevents the soft baffle 10 from applying excessive force to the liquid crystal glass, thereby damaging the liquid crystal glass.

[0039] During the movement of the pressing plate 6, the pushing plate 7 is synchronously driven to move, so that the cleaning plate 8 is in contact with the liquid crystal glass. Based on the continuous movement of the pressing plate 6, the pushing plate 7 drives the cleaning plate 8 to slide on the surface of the liquid crystal glass to clean its surface, thereby preventing the subsequent hard objects on the liquid crystal glass from affecting the cutting blade 16. Then, the servo motor 21 is started to drive the threaded rod 14 to rotate, so that the moving plate 15 drives the cutting blade 16 to slide on the upper and lower surfaces of the liquid crystal glass to cut the liquid crystal glass.

[0040] After the liquid crystal glass is cut, based on the movement of the extrusion plate 19, the liquid crystal glass moves to the surface of the conveying unit 1, so that the conveying unit 1 drives the liquid crystal glass to move to the bottom of the fixed plate 29, and the second electric push rod 28 is started, so that its output end drives the fixed plate 29 to move, and fixes the liquid crystal glass, so that the liquid crystal glass is fixed between the fixed plate 29 and the vibration plate 26. Then, the high-frequency vibration motor 24 is started, so that its output end drives the vibration rod 25 to vibrate, so that the vibration force of the vibration plate 26 is transmitted to the liquid crystal glass. According to the principle of vibration, the cutting cracks on the glass substrate with cutting cracks are fully extended in the thickness direction of the glass substrate, thereby achieving the effect of crack separation and completing the processing of the liquid crystal glass.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
