Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, and more specifically, the utility model relates to an automatic fine cutting device for a glass substrate for display. Background Art

[0002] In the production process of glass, after the glass liquid enters the forming equipment, an ultra-thin glass sheet is formed, and then the glass sheet needs to be cross-cut and longitudinally cut. Although the cross-cutting and longitudinal cutting have initially cut the glass substrate, there may still be certain dimensional errors. Therefore, it is necessary to perform fine cutting on the glass substrate. Fine cutting can further correct these errors to ensure that the dimensional accuracy of the glass substrate meets the customer's requirements. At the same time, fine cutting can also remove burrs and chipping on the edge through a more refined cutting process, improving the smoothness and flatness of the edge.

[0003] The existing glass substrate fine cutting device usually identifies the position, shape and size of the glass through sensors, and then the control system uses a cutting tool head to cut it according to this information to ensure the accuracy of cutting. Currently, the cutting of the glass substrate can generally only be performed in a single direction. When it is necessary to cut the glass substrate in the length direction, the operator needs to adjust the position of the glass substrate and place it on the cutting table. Under the action of the sensor, the control system cuts it according to the customer's requirements. When it is also necessary to cut the glass substrate in the width direction, the operator needs to remove the glass substrate that has just been cut in the length direction from the cutting table, readjust the direction, and then use the control system to control the cutting tool head to cut the glass substrate. This cutting method has the following problems: First, when one side of the glass substrate is cut, manually adjusting the position of the glass substrate is required to cut the other side of the glass substrate, which greatly increases the workload of the personnel, reduces the cutting efficiency, and increases the labor cost; Second, manual adjustment is prone to position deviation and needs to be adjusted repeatedly, which not only wastes human resources but also easily leads to inaccurate cutting, affecting the final cutting quality of the glass substrate and unable to meet the customer's requirements.

An adjusting device 4 for facilitating the adjustment of the position of the glass substrate is slidably installed on the cutting table 2. A reversing device 6 for facilitating the replacement of the cutting direction of the cutting head 5 is installed on the cutting table 2. A moving device 7 is installed on the reversing device 6, and the moving device 7 is used to control the movement of the cutting head 5.

[0032] Furthermore, the reversing device 6 includes a turntable 61, a fixing rod 62, a connecting rod 63, and a first motor 64 fixedly installed on the cutting table 2.

The first motor 64 in this embodiment is a servo motor. The first motor 64 drives the connecting rod 63 to rotate 90° in the clockwise direction. The rotation of the connecting rod 63 drives the rotation of the turntable 61 and the fixing rod 62, so that the cutting head 5 can still cut the glass substrate according to actual needs after rotating 90°.

[0033] Further, the adjusting device 4 includes an upper slide plate 41, a lower slide plate 42, a first cylinder 43, and a second cylinder 44. The number of the first cylinders 43 can be multiple. In this embodiment, the number of the first cylinders 43 is two, so as to ensure the stability of the movement of the lower slide plate 42. The lower slide plate 42 is horizontally slidably connected to the cutting table 2. The upper slide plate 41 is longitudinally slidably connected to the lower slide plate 42. The first cylinder 43 is fixedly installed on the cutting table 2. The piston rod of the first cylinder 43 is fixedly connected to the lower slide plate 42. The second cylinder 44 is fixedly installed on the lower slide plate 42 away from the reversing device 6. The piston rod of the second cylinder 44 is slidably connected to the upper slide plate 41.

[0034] Further, the bottom of the upper slide plate 41 is higher than the top of the cutting table 2, so as to ensure the normal movement of the upper slide plate 41, enabling it to move below the tool head 5 for cutting the glass substrate.

[0035] Further, the moving device 7 includes a transverse moving device 71 and a longitudinal moving device 72. The transverse moving device 71 is used to control the transverse movement of the tool head 5, and the longitudinal moving device 72 is used to control the vertical movement of the tool head 5.

The lead screw 711 is drivingly connected to the second motor 713. The second motor 713 is fixedly installed on the fixed rod 62. The second motor 713 drives the lead screw 711 to rotate, thereby driving the slider 712 to move horizontally along the direction of the lead screw 711, thus realizing the transverse movement of the tool head 5 for cutting the glass substrate.

[0037] Further, the longitudinal moving device 72 includes a connecting plate 721 and a third cylinder 722. The third cylinder 722 is fixedly installed on the slider 712. The piston rod of the third cylinder 722 is fixedly connected to the connecting plate 721. The tool head 5 and the sensor 1 are fixedly installed at the bottom of the connecting plate 721. When the sensor 1 identifies the position of the glass, the third cylinder 722 is activated, thereby driving the tool head 5 to move downward to cut the glass substrate.

[0038] Further, a connecting seat 8 is installed at the bottom of the slider 712. A guide rod 9 is fixedly installed on the connecting seat 8. The guide rod 9 passes through the connecting plate 721 and is slidably connected thereto. The arrangement of the guide rod 9 can play a good guiding role in the movement of the tool head 5, ensuring that the tool head 5 always moves along the direction of the guide rod 9 and preventing deviation in movement.

[0039] Furthermore, the fixing device 3 includes a suction cup 31 and a vacuum pump 32, the suction cup 31 is fixedly mounted on the top of the upper slide plate 41, the vacuum pump 32 is mounted on the side of the upper slide plate 41, the upper slide plate 41 is hollow inside, and the suction cup 31 is connected to the vacuum pump 32 through a hollow channel inside the upper slide plate 41.

[0040] Furthermore, both the upper slide plate 41 and the lower slide plate 42 are provided with a bump 10, and the bump 10 is slidably connected to the groove 11 provided on the lower slide plate 42 and the cutting table 2, respectively. The width of the top of the vertical cross-section of the bump 10 is smaller than the width of the bottom thereof, thereby preventing the bump 10 from detaching from the groove 11, thereby ensuring the smooth progress of the precision cutting of the glass substrate.

[0041] The working principle of this embodiment is as follows:

[0042] The glass substrate is placed on the cutting table 2, and the vacuum pump 32 is started. The glass substrate is fixed on the cutting table 2 under the action of the suction cup 31. Then, the specific parameters are adjusted through the control system according to the customer's requirements, and the cylinder 1 43 is started. The cylinder 1 43 pushes the lower slide 42 to move. After the sensor 1 recognizes that the glass substrate has reached the predetermined position, the cylinder 3 722 is started to drop the cutter head 5 close to the glass substrate, and then the motor 2 713 is started to drive the lead screw 711 to rotate, and then drive the slider 712 to reciprocate linearly, thereby completing the cutting of one side of the glass substrate and the retraction of the cutter head 5, and then the motor 1 64 is started. The rotation of the motor 1 64 drives the rotation of the turntable 61, and then drives the fixing rod 62 to rotate 90 degrees clockwise, and then the cylinder 1 43 and the cylinder 2 44 are used to adjust the positions of the lower slide 42 and the upper slide 41. Since the upper slide 41 is higher than the cutting table 2, it can ensure that the glass substrate on the upper slide 41 is placed below the cutter head 5. Repeat the above operation to complete the cutting of the other side of the glass substrate, meeting the actual requirements of the customer.

[0043] The technical effect of the embodiment of the utility model is that the automatic precision cutting device for glass substrates can directly realize longitudinal and transverse cutting of glass substrates without manually adjusting the position of the glass substrates, thereby reducing the workload of personnel, realizing automatic operation of glass substrate cutting, improving cutting efficiency, ensuring the cutting quality of glass substrates, and meeting the actual needs of customers.
