In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0032] The present embodiment provides a cutting device for cutting a carrier glass 40 into a desired size, which is mainly used for producing display, which will not be described here. Specifically, as shown in Figure 1 The cutting device includes a fixedly arranged frame body 10, a driving assembly 20 mounted on the frame body 10, and a cutting assembly 30 connected to the output end of the driving assembly 20, the driving assembly 20 is used to drive the cutting assembly 30 to cut the carrier glass 40 along the cutting path, the cutting assembly 30 includes a rotary driving member 31, a knife holder 32 and a knife wheel 33, the rotary driving member 31 is connected to the output end of the driving assembly 20, the rotary driving member 31 can drive the knife holder 32 to rotate, the knife holder 32 is connected to the output end of the rotary driving member 31, the knife holder 32 includes a plurality of branches 321, the end of each branch 321 is rotatably connected with the knife wheel 33, the knife wheel 33 is used to cut the carrier glass 40.

[0033] In use, the rotary driving member 31 and the holder 32 are moved along the cutting path by the driving assembly 20, and the holder 32 drives the cutter wheel 33 to move on the glass substrate 40 to perform cutting. When the cutter wheel 33 needs to be replaced, the system controls the rotary driving member 31 to rotate the output shaft to drive the holder 32 to rotate by a preset angle, so as to rotate the used cutter wheel 33 to one side, and rotate the next new cutter wheel 33 to the designated cutting position. Until all the cutter wheels 33 are used up, the equipment stops and all the cutter wheels 33 are replaced. This arrangement improves the continuity and stability of cutting, reduces the number of cutter wheel 33 replacement, reduces the equipment failure rate caused by improper replacement, and reduces the number of equipment downtime, thereby improving the overall equipment uptime and production efficiency.

[0034] Optionally, the center of the holder 32 is connected to the output end of the rotary driving member 31, and the number of branches 321 is set to an even number. The even number of branches 321 are uniformly spaced along the circumference with the output shaft of the rotary driving member 31 as the center. By setting the even number of branches 321, the overall stress is more uniform when the holder 32 rotates, and the rotation is more stable, which to some extent prolongs the service life of the rotary driving member 31. For example, the number of branches 321 and cutter wheels 33 can be set to two, four, six or more if the space is sufficient, which is not specifically limited here.

[0035] Optionally, in the present embodiment, as shown in Figure 1 The holder 32 is in a cross-shaped structure and includes four branches 321. That is, the number of cutter wheels 33 is also set to four, and the equipment stops and replaces only after all the four cutter wheels 33 are used up. The rotation is stable, the number of cutter wheel 33 replacement is reduced, and the number of equipment downtime is reduced, thereby improving the overall equipment uptime and production efficiency.

[0036] It should be noted that in the embodiment, the condition for determining whether the cutter wheel 33 needs to be replaced is the cutting distance, that is, by acquiring the cutting distance of the cutter wheel 33 at the cutting position, it is determined whether the cutter wheel 33 needs to be replaced, when the cutting distance reaches the preset distance, the system controls the output shaft of the rotary drive 31 to rotate the cutter holder 32 by a preset angle, so as to rotate the used cutter wheel 33 to one side, and rotate the next new cutter wheel 33 to the designated cutting position for cutting. For example, the preset distance of the cutter wheel 33 is set to 10,000 meters, that is, the cutter wheel 33 is judged to need to be replaced when it cuts 10,000 meters. In the prior art, the cutter wheel 33 stops once every 10,000 meters, and needs to stop four times when cutting 40,000 meters. In the embodiment, each cutter wheel 33 can cut 10,000 meters, and four cutter wheels 33 can cut 40,000 meters before stopping once, and then all the cutter wheels 33 are replaced. Therefore, compared with the prior art, the embodiment reduces the number of equipment downtime, thereby improving the overall equipment uptime and production efficiency, and after improvement, the uptime can be improved by about 10%.

[0037] It should be noted that the control of the rotary drive 31 is controlled by a PLC program, and the detection of the cutting distance of the cutter wheel 33 can be realized by an encoder and a PLC. The encoder can be connected with the rotating shaft of the cutter wheel 33, so as to ensure that the encoder outputs a corresponding number of pulses every time the cutter wheel 33 moves a certain distance, thereby converting the cutting distance into an electrical pulse signal. The PLC selects a PLC with a high-speed counter module or a built-in high-speed counter function (which belongs to the prior art) to count the pulse signal from the encoder at high speed and high accuracy. The input program of the PLC is designed to convert the pulse signal into the cutting distance, and compare the cutting distance with the preset distance. When the cutting distance is equal to the preset distance, the PLC program controls the output shaft of the rotary drive 31 to rotate, so as to realize the replacement of the cutter wheel 33. After replacement, the counter is reset and the pulse signal output by the encoder on the new cutter wheel 33 is counted again. The cycle is repeated until all the cutter wheels 33 are used up.

[0038] In an optional embodiment, the rotary drive 31 can be a rotary cylinder. In another optional embodiment, the rotary drive 31 can also be an electric motor, both of which can realize the rotation of the cutter holder 32, which is not specifically limited here.

[0039] In an optional embodiment, as shown in Figure 1 Fig. 2, the driving assembly 20 includes a first driving member 21 and a second driving member 22. The first driving member 21 is fixed to the frame 10, and the second driving member 22 is connected to the output end of the first driving member 21. The rotary drive 31 is connected to the output end of the second driving member 22. The first driving member 21 can drive the second driving member 22 to move in the horizontal direction, and the second driving member 22 can drive the rotary drive 31 to move in the vertical direction. Figure 1X direction in the cutting device 1, and the vertical direction is Figure 1 The Y direction in the cutting device 1, the first driving member 21 mainly drives the cutter wheel 33 to move along the cutting path, and the second driving member 22 mainly drives the cutter wheel 33 to move downward to contact the carrier plate glass 40.

[0040] It should be noted that when the cutting distance of the cutter wheel 33 located at the cutting position reaches the preset distance, the PLC control program needs to control the first driving member 21 to stop working, and the output end of the second driving member 22 drives the cutter holder 32 to lift, and then the output shaft of the rotary driving member 31 drives the cutter holder 32 to rotate by a preset angle, so as to rotate the new cutter wheel 33 to the specified cutting position. After replacement, the PLC control program controls the output end of the second driving member 22 to drive the cutter holder 32 to descend to the cutter wheel 33 to contact the carrier plate glass 40, and then controls the first driving member 21 to continue to work to complete the subsequent cutting. The process time is very short.

[0041] In the embodiment, the first driving member 21 is a linear motor, and the second driving member 22 is a lifting cylinder. In another alternative embodiment, the first driving member 21 and the second driving member 22 can also adopt any other driving member that can drive linear movement, which will not be described here.

[0042] In an alternative embodiment, the cutter holder 32 is provided with a detection member 50, which is used to detect whether the cutter wheel 33 reaches the specified cutting position, so as to avoid the appearance of defective products. In an alternative embodiment, the detection member 50 can be a potentiometer type angle sensor, which can directly detect the rotation angle of the cutter holder 32. Taking the cross-shaped cutter holder 32 as an example, when the cutter holder 32 rotates by 90 degrees, it indicates that the new cutter wheel 33 reaches the specified cutting position and can normally complete the cutting. If the rotation angle of the cutter holder 32 is greater than or less than 90 degrees, it is judged that it cannot work normally, and the PLC starts the alarm program. At this time, a fault may occur, which needs to be checked by the operator. In another alternative embodiment, the detection member 50 can also be a rotary encoder installed on the rotating shaft of the cutter holder 32 and rotates with the cutter holder 32, which can also detect the rotation angle of the cutter holder 32.

[0043] The embodiment also provides a cutter wheel replacement method, which is realized by using the above cutting device, and the specific steps include:

[0044] S10: Obtain the cutting distance of the cutter wheel 33 located at the cutting position;

[0045] S20: When the cutting distance reaches the preset distance, control the output shaft of the rotary driving member 31 to drive the cutter holder 32 to rotate by a preset angle, so as to rotate the cutter wheel 33 to one side and rotate the next new cutter wheel 33 to the specified cutting position for cutting;

[0046] S30: repeating S20 until all the cutter wheels 33 are used up, stopping and replacing all the cutter wheels 33.

[0047] The cutter wheel replacement method provided by the embodiment can realize the switching use of the cutter wheels 33, and the cutting continuity and stability are improved, the number of replacement of the cutter wheels 33 is reduced, the equipment failure rate caused by improper replacement is reduced, and the number of equipment downtime is reduced, thereby improving the start-up rate and production efficiency of the whole equipment.

[0048] In the embodiment, since the tool holder 32 is a cross-shaped structure and includes four branches 321, the preset angle in step S20 is 90 degrees. That is, the tool holder 32 can realize the switching use of the cutter wheels 33 every 90 degrees of rotation.

[0049] Alternatively, in S20, the rotation angle of the tool holder 32 is detected by the detection member 50 during rotation to determine whether the preset angle is met, if yes, the new cutter wheel 33 continues to perform the cutting operation, if not, the cutting device is alarmed and stopped to avoid the appearance of defective products. Specifically, taking the cross-shaped tool holder 32 as an example, when the tool holder 32 rotates 90 degrees, it means that the new cutter wheel 33 reaches the specified cutting position and can normally complete the cutting; if the rotation angle of the tool holder 32 is greater than or less than 90 degrees, it is judged that it cannot work normally, and the PLC starts the alarm program, at this time, the fault may occur and needs to be checked by the operator.

[0050] It should be noted that the cutting device includes an alternating mode and a fixed mode, and the above process is for the alternating mode, that is, without specifying the use of a certain cutter wheel 33, but automatically switching to the adjacent next cutter wheel 33 after the use of one cutter wheel 33 is completed, until all the cutter wheels 33 are used up. The fixed mode needs to manually select the cutter wheel 33 to be used, for example, taking four cutter wheels 33 as an example, which are marked as No. 1 to No. 4, the operator can select the cutter wheel 33 to be used on the operation screen in advance, for example, selecting No. 2 and No. 3 cutter wheels 33, after the use of No. 2 cutter wheel 33 is completed, the output shaft of the rotating driving member 31 is rotated by a corresponding angle to switch to No. 3 cutter wheel 33. Both modes can realize the automatic switching of the cutter wheels 33, and the mode selection is flexible.

[0051] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the implementation modes are not required or can not be exhausted. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
