[0029] like Figures 1 to 4 As shown, this embodiment shows a cross-cutting machine for liquid crystal glass production, which includes: a main frame assembly 10, a lifting assembly 20, a marking assembly 30 and a support assembly 40. The marking assembly 30 is vertically lifted and lowered on the main frame assembly 10 by the lifting assembly 20. The marking assembly 30 includes a marking machine 31, an actuator 32 and a metal drag chain 33 for protecting the air pipe and line used by the marking machine 31. The marking machine 31 is horizontally movably arranged on the actuator 32, the metal drag chain 33 is connected to the marking machine 31, and the support assembly 40 is arranged below the marking machine 31 for supporting the metal drag chain 33.

[0030] By applying the technical solution of this embodiment, the cross-cutting machine for liquid crystal glass production provided by this application is provided with a scribing assembly 30 which is vertically lifted and lowered on the main frame assembly 10 by the lifting assembly 20 so that the scribing machine 31 moves to a specific position, and then drives the scribing machine 31 to cut the glass substrate by the actuator 32, and reduces the falling amplitude of the metal drag chain 33 by arranging a support assembly 40 under the scribing machine 31, thereby reducing the influence on the linear motion of the scribing machine 31 during the dragging process of the metal drag chain 33. The technical solution of this application effectively solves the problem in the prior art that the metal drag chain 33 affects the linear motion of the scribing machine 31 during the dragging process.

[0031] like Figures 2 to 4As shown, in the technical solution of this embodiment, the support assembly 40 includes a support frame 41, a support shaft 42 and a support roller 43. The support shaft 42 is arranged on the support frame 41, and the support roller 43 is rotatably mounted on the support shaft 42 through bearings arranged at both ends thereof, and the support roller 43 rolls to support the metal drag chain 33. The support shaft 42 has external threads at both ends, and the support shaft 42 is mounted on the support frame 41 by two fixing nuts. The two ends of the support roller 43 are rotatably mounted on the support shaft 42 through bearings, and an elastic retaining ring for the shaft can also be arranged on the support shaft 42. Such arrangement limits the movement of the bearing in the axial direction, thereby avoiding the axial shaking of the support roller 43 during the movement. When the metal drag chain 33 is driven by the marking machine 31 to move to the half position, the metal drag chain 33 begins to contact the support assembly 40. Since the support assembly 40 supports the metal drag chain 33, the dragging force of the marking machine 31 on the metal drag chain 33 is shared, and the falling amplitude of the metal drag chain 33 is effectively reduced. This ensures that the linear motion of the marking machine 31 is not affected. At the same time, the support roller 43 converts the sliding friction into rolling friction, thereby reducing the wear of the metal drag chain 33, and avoiding abnormal conditions such as leakage of electricity and air due to long-term friction of the gas circuit, control circuit, power circuit and other circuits in the metal drag chain 33.

[0032] like Figures 2 to 4 As shown, in the technical solution of this embodiment, protrusions are arranged at both ends of the support roller 43 along the circumferential direction, the length of the support shaft 42 is greater than the width of the metal drag chain 33, and an anti-wear layer is fixedly arranged on the surface of the support roller 43. The protrusions can prevent the metal drag chain 33 from leaving the running track, and the length of the support shaft 42 is greater than the width of the metal drag chain 33. Such a setting makes the support shaft 42 better support the metal drag chain 33. The surface of the support roller 43 is provided with an anti-wear layer, and the material of the anti-wear layer can be polyoxymethylene, which has high heat resistance, bending strength, and fatigue resistance, and has excellent wear resistance. During use, the wear of the metal drag chain 33 can be reduced, and the safety hazard caused by the wear of the line in the metal drag chain 33 can be avoided.

[0033] like Figure 2 and Figure 3As shown, in the technical solution of this embodiment, the support frame 41 includes a vertical frame 411 and a horizontal frame 412. The height of the vertical frame 411 is equal to the rotation diameter of the metal drag chain 33, and the length of the horizontal frame 412 is equal to the length of the support roller 43. The height of the vertical frame 411 is equal to the rotation diameter of the metal drag chain 33. This arrangement makes the support position of the support frame 41 just on the motion track of the metal drag chain, and the metal drag chain 33 will not generate other direction components on the marking machine due to insufficient or excessive height of the support frame. By setting the horizontal frame 412, on the one hand, the horizontal frame 412 can play the role of reinforcing ribs to make the structure of the support assembly 40 more stable. On the other hand, the horizontal frame 412 also has a certain limiting and guiding effect on the metal drag chain 33 in the vertical direction, and it is also more convenient for the support frame 41 to be fixed on the drag chain groove 34.

[0034] like Figure 1 As shown, in the technical solution of this embodiment, the lifting assembly 20 includes a lifting beam 21 and a lifting drive structure 22 for driving the lifting beam 21 to move. The lifting drive structure 22 is arranged on the main frame assembly 10, and the actuator 32 is arranged on the lifting beam 21. The lifting beam 21 is driven up and down by the lifting drive structure 22, so that the speed of the lifting beam 21 is the same as the speed of the glass from top to bottom, so that the scribing machine 31 fixed on the lifting beam 21 is convenient for horizontal line cutting of the glass substrate. When the glass substrate, the lifting beam 21 and the actuator 32 arranged on the lifting beam 21 are synchronously descended, the scribing machine 31 performs scribing under the lateral driving force of the actuator 32. When the glass descends to the specified position, the scribing machine 31 completes the scribing work. The actuator 32 is used to control the motion of the scribing machine 31. This method has the advantages of high control accuracy and good stability, and can realize accurate control of horizontal line cutting, ensure cutting accuracy, and improve product yield.

[0035] like Figure 1 As shown, in the technical solution of this embodiment, the lifting drive structure 22 includes a motor 221 and lead screws 222 arranged on both sides of the main frame assembly 10, the lead screws 222 are provided with nuts 223 matched therewith, the lifting beam 21 is fixedly arranged on the nuts 223, and the lead screws 222 on both sides of the main frame assembly 10 are connected to the motor 221. The arrangement of the lead screw 222 and the nut 223 can convert the axial movement of the lead screw 222 into the linear movement of the nut 223. This transmission method has the advantages of stable movement, high load capacity and high precision. With the motor 221, the lifting beam 21 and the glass can achieve synchronous movement, thereby ensuring the horizontality of glass cutting.

[0036] like Figure 1As shown, in the technical solution of this embodiment, the marking assembly 30 also includes a drag chain slot 34 and a plurality of chain slot fixing plates 35. The metal drag chain 33 is arranged in the drag chain slot 34, and the drag chain slot 34 is fixedly connected to the lifting beam 21 through the plurality of chain slot fixing plates 35. The drag chain slot 34 has a certain supporting effect on the metal drag chain 33 and a guiding effect in the horizontal direction. The drag chain slot 34 moves synchronously with the lifting beam 21 through the plurality of chain slot fixing plates 35, so that the metal drag chain 33 is always in a state parallel to the actuator 32, reducing the drag force in other directions caused by the metal drag chain 33 on the actuator 32, and further ensuring that the linear motion of the marking machine 31 is not affected by the metal drag chain 33.

[0037] like Figure 1 and Figure 4 As shown, in the technical solution of this embodiment, the support components 40 are arranged in two groups, and the two groups of support components 40 are fixedly arranged on the drag chain groove 34 at a certain distance. The arrangement of the two groups of support components 40 makes the support of the metal drag chain 33 more stable, and the number of support components 40 and the spacing distance of the support components 40 can be selected according to the support conditions of the metal drag chain 33.

[0038] like Figure 1 As shown, in the technical solution of this embodiment, the tail end of the scribing machine 31 is connected to the metal drag chain 33. Such a setting facilitates the metal drag chain 33 to move horizontally with the actuator 32, and at the same time, such a position relationship will not cause the metal drag chain 33 to affect the cutting of the glass substrate by the scribing machine 31.

[0039] According to another aspect of the present application, a liquid crystal glass production line is also provided, which includes the above-mentioned cross-cutting machine for liquid crystal glass production. After the glass raw materials are melted, formed and annealed, the first process is to cut them in the length direction through the scribing machine 31 of the cross-cutting machine. The scribing assembly 30 is vertically lifted and installed on the main frame assembly 10 through the lifting assembly 20 to move the scribing machine 31 to a specific position, and then the scribing machine 31 is driven by the actuator 32 to cut the glass substrate. By arranging a support assembly 40 under the scribing machine 31, the falling amplitude of the metal drag chain 33 is reduced, thereby reducing the influence on the linear motion of the scribing machine 31 during the dragging process of the metal drag chain 33, thereby ensuring that the scribing machine 31 cuts the glass substrate in a straight line.

[0040] In summary, through the above technical solutions, the cross-cutting machine for liquid crystal glass production provided by the present application and the production line having the same, the scribing assembly 30 is installed on the main frame assembly 10 through the lifting assembly 20 to vertically lift and lower the scribing machine 31 to a specific position, and then the scribing machine 31 is driven by the actuator 32 to cut the glass substrate, and the support assembly 40 is arranged below the scribing machine 31 to reduce the falling amplitude of the metal drag chain 33, thereby reducing the influence on the linear motion of the scribing machine 31 during the dragging process of the metal drag chain 33. The technical solution of the present application effectively solves the problem in the prior art that the metal drag chain affects the linear motion of the scribing machine during the dragging process.

[0041] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
