Reference in this application to "depth of cut", "depth of cut" and the like is to a dimension perpendicular to the cutting plane. Reference in this application to a "cutting plane" is to a plane of glass to be cut on which the edge of the cutter wheel will move for the purpose of cutting the glass.

The apparatus for cutting glass of the present invention comprises: a cutting mechanism for cutting the glass; the guide mechanism is connected with the cutting mechanism and used for guiding the cutting mechanism to move along the direction vertical to the cutting plane; and the driving mechanism is connected with the guide mechanism and is used for driving the guide mechanism to guide the cutting mechanism to move along the direction vertical to the cutting plane.

As shown in fig. 2, the cutting mechanism includes a cutter wheel 1 and a handle 15 connected to the cutter wheel 1. The guide mechanism comprises a movable sliding table 5 and a screw rod assembly, one end of the movable sliding table 5 is connected with the tool handle 15, the other end of the movable sliding table is connected to the screw rod assembly in a sliding mode, and the movable sliding table 5 drives the cutting mechanism to move relative to the screw rod assembly along a direction perpendicular to a cutting plane (namely, the up-down direction in fig. 2). The screw assembly includes a screw 9 connected to the drive mechanism, a ball bearing 10 engaged with the screw 9, and a pair of fixed bearings 8, one of the fixed bearings 8 being disposed at one end of the screw 9, the other of the fixed bearings 8 being disposed at the other end near the screw 9. Adopt lead screw assembly, can ensure to remove slip table 5 for lead screw assembly along linear motion, and then guarantee to remove slip table 5 and drive break bar 1 and remove along the direction of perpendicular to cutting plane.

In a preferred embodiment, the guide mechanism further comprises a pair of guide rails 12 and a pair of linear bearings 11 for guiding the moving slide 5 in a direction perpendicular to the cutting plane. Both ends of each guide rail 12 are connected to the fixed bearings 8, respectively, and a pair of guide rails 12 are provided on opposite sides of the lead screw 9, respectively. A pair of linear bearings 11 are provided on the moving slide table 5 and are slidably connected with a pair of guide rails 12, respectively, and the provision of the guide rails 12 can further improve the moving accuracy of the moving slide table 5.

In a preferred embodiment, one end of the moving slide 5 is provided with a shank insertion hole (not shown), by means of which a shank 15 is connected to one end of the moving slide 5 by a pin 14, and the other end of the moving slide 5 is connected to the screw 9 by a ball bearing 10.

In a preferred embodiment, the drive mechanism comprises a motor 13 and a transmission mechanism connecting the motor 13 with the other end of the lead screw 9. The transmission mechanism comprises a synchronous pulley 7 and a synchronous belt 6 which connects the synchronous pulley 7 with a motor 13, and the synchronous pulley 7 is connected with the other end of the screw 9. In a preferred embodiment, the motor 13 is a servo motor, and driving with the servo motor 13 allows for better control of the cutting position and ensures accurate feed depth.

The action process of the device for cutting glass comprises the following steps: the servo motor 13 drives the synchronous belt pulley 7, so as to drive the screw 9 to perform rotary motion, the ball bearing 10 connected with the screw 9 converts the rotary motion of the screw 9 into linear motion, so as to drive the moving sliding table 5 connected with the ball bearing 10 to perform linear motion, and finally drive the knife flywheel 1 to move along the direction perpendicular to the cutting plane, so as to realize adjustment and control of the feed depth. The moving slide table 5 can be moved up or down (in the direction shown in fig. 2) in the longitudinal direction of the screw shaft 9 by the forward and reverse rotation action of the screw shaft 9.

Furthermore, the drive mechanism of the present invention may also be communicatively connected to a PLC control system (not shown) that may automatically compensate for the wear of the cutting mechanism by controlling the amount of cutting by the cutting mechanism.

Specifically, when glass is cut, the cutter wheel of the cutting mechanism is gradually worn away as the use time increases, which is disadvantageous for effectively cutting the glass, and thus there is a problem that the cutting accuracy is lowered. In order to solve the technical problem, in actual production, according to the using meter number of the cutter wheel and the thickness of the glass to be cut, a PLC control system is programmed to continuously and automatically compensate the problem that the glass is cut continuously due to the loss of the cutting mechanism, so that the manual adjustment and the workload are reduced, and the production stability is improved. It will be understood by those skilled in the art that the number of meters of use of the cutter wheel refers to the total thickness of glass that the cutter wheel is theoretically capable of cutting, for example, if a piece of glass is 1.35m thick, and the cutter wheel is theoretically capable of cutting 1000 such pieces of glass, then the number of meters of use of the cutter wheel is 1350 m.

Therefore, when the number of meters used by the cutter wheel is 1350m and the thickness of the glass to be cut is 1.35m, the PLC control system can be set to perform compensation on the cutter wheel once every 200 pieces of glass are cut, and the compensation is performed for 4 times. At this time, the cutter wheel already cuts 1080m thick glass, namely, 1080m of the actual using number of meters of the cutter wheel reaches the upper limit, and the cutter wheel needs to be replaced by a new cutter wheel. It will be appreciated by those skilled in the art that there may be different numbers of compensations for different cutter wheels used meters and for different thicknesses of glass to be cut.

During the compensation process, the PLC control system automatically compensates the problem of continuous glass cutting caused by the loss of the cutter wheel by increasing the cutting amount of the cutter wheel according to a preset program. It should be understood by those skilled in the art that the cutting amount of the cutter wheel can include parameters such as cutting speed, cutting depth, etc., and the PLC control system automatically increases the cutting speed and the cutting depth according to the program setting to compensate the influence of the abrasion of the cutter wheel on the cutting quality. In addition, when the number of the actually used meters of the cutter wheel reaches the upper limit, the PLC control system controls the alarm device to give an alarm to prompt that the cutter wheel cannot be used continuously, field workers replace the new cutter wheel in time, and the PLC control system automatically restores the initial value and continues production in the next period.
