Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a device for preventing glass from breaking. Background Art

[0002] During the glass processing, the glass pieces need to be broken after being cut to form multiple small pieces of glass. In the related art, the operator can break the cut glass pieces along the cutting line through a manual breaking table. However, when cutting the glass pieces, it is necessary to use volatile liquids such as cutting oil or kerosene as cutting fluids to cool the cut pieces and use the molecular expansion effect to make the glass pieces easier to break.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the description of the present invention, the reference to the terms "one embodiment", "some embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] During the glass processing, the glass pieces need to be broken after being cut to form multiple small pieces of glass. In the related art, the operator can break the cut glass pieces along the cutting line by a manual breaking table. However, when cutting the glass pieces, it is necessary to use volatile liquids such as cutting oil or kerosene as cutting fluid to cool the cutting pieces and make the glass pieces easier to break by using the molecular expansion effect. However, the presence of cutting fluid will also make the cutting line unclear. For example, refer to Figure 5The glass sheet 300 has through knife lines 310 and non-through knife lines 320. There are non-through knife lines 320 on both sides of the longitudinal through knife line 310, and the positions of the non-through knife lines 320 on both sides are relatively close. When the cutting line is blurred due to the cutting fluid, in the subsequent sheet breaking operation, the operator is likely to mistake the non-through knife lines 320 for the through knife lines 310. If the sheet breaking is started at the non-through knife lines 320 first, the glass sheet on at least one side of the through knife line 310 will not be broken according to the correct non-through knife lines 320, resulting in damage to the glass sheet 300, which in turn leads to an increase in the scrap rate and an increase in production costs.

[0033] Based on this, the first embodiment of the utility model provides an anti-breakage device for breaking the glass sheet 300 along the cutting line, referring to Figures 1 to 4 The foolproof sheet breaking device includes a sheet breaking workbench 100 and a display unit 200 . The sheet breaking workbench 100 is used to carry a glass sheet 300 . The display unit 200 is located above the sheet breaking workbench 100 , and is used to display a cutting line pattern of the glass sheet 300 .

[0034] Reference Figure 5 , the cutting lines include a plurality of through knife lines 310 and a plurality of non-through knife lines 320, wherein the through knife lines 310 are drawn with solid lines, and the non-through knife lines 320 are drawn with dotted lines, the extending directions of the through knife lines 310 and the non-through knife lines 320 intersect, the through knife lines 310 extend from one edge of the glass sheet 300 to the other edge, and the non-through knife lines 320 extend from one edge of the glass sheet 300 to the through knife lines 310, and the non-through knife lines 320 are staggered on both sides of at least one through knife line 310, and the cutting lines extend in the horizontal or vertical direction of the glass sheet 300. When performing the sheet breaking operation, the operator can refer to the cutting line pattern displayed on the display unit 200 to determine the position of the through knife lines 310, and first break the sheet at the through knife lines 310, and then break the sheet at the non-through knife lines 320, which can reduce the possibility that the operator cannot clearly identify the cutting lines and causes the wrong sheet breaking sequence, thereby reducing the scrap rate and reducing the production cost.

[0035] In some embodiments, reference Figure 1 The display unit 200 is a display screen, and a cutting line pattern is displayed on the display unit 200. When breaking the glass sheet, the operator can judge the position of the cutting line 310 of the glass sheet 300 by comparing the cutting line pattern on the display unit 200, and then break the glass sheet at the cutting line 310 first.

[0036] In other embodiments, reference Figure 2The display unit 200 is a projector, the lens of the display unit 200 faces the sheet breaking workbench 100, and the display unit 200 is used to project the cutting line pattern on the surface of the glass sheet 300. Compared with setting the display unit 200 as a display screen, setting the display unit 200 as a projector can more intuitively indicate the position of the cutting line 310. When performing the sheet breaking operation, the operator does not need to look up to check the display screen, but only needs to refer to the projection on the surface of the glass sheet 300 to know the position of the cutting line 310, which is conducive to reducing the work intensity of the operator.

[0037] Furthermore, in the cutting line pattern displayed by the display unit 200, the color of the through-cut line 310 is different from the color of the non-through-cut line 320, which can more intuitively distinguish different types of lines and provide a clearer prompt for the operator to reduce the possibility of misjudgment. More specifically, in the cutting line pattern displayed by the display unit 200, the through-cut line 310 is red, which is more eye-catching and helps to attract the attention of the operator to further reduce the possibility of misjudgment.

[0038] Further, refer to Figures 1 to 4 The sheet breaking workbench 100 includes a support portion 110, a top-breaking portion 120 and an air-floating portion 130. The top-breaking portion 120 is movably connected to the support portion 110. The top-breaking portion 120 is arranged in a cross shape. The air-floating portion 130 is arranged on the support portion 110 between the top-breaking portions 120. The upper surface of the air-floating portion 130 is used to carry the glass sheet 300. The top-breaking portion 120 can move relative to the air-floating portion 130 in a vertical direction to extend or retract relative to the upper surface of the air-floating portion 130. Figure 3 The air flotation part 130 has an air blowing hole 131, and the air blowing hole 131 can blow air outward, so that the glass piece 300 on the air flotation part 130 is lifted by the air flow, which is beneficial to reduce the friction between the glass piece 300 and the breaking workbench 100, reduce the resistance to the movement of the glass piece 300, and enable the operator to move or rotate the glass piece 300 more effortlessly.

[0039] When performing the sheet breaking operation, the operator first determines the position of the through knife line 310, and manually operates to make the top breaking part 120 corresponding to the through knife line 310 extend relative to the air flotation part 130 and abut against the through knife line 310 of the glass sheet 300, so that the glass sheet 300 is broken at the through knife line 310; then moves or rotates the broken glass sheet 300, so that the non-through knife line 320 corresponds to a top breaking part 120, and manually operates to make the top breaking part 120 of the non-through knife line 320 extend relative to the air flotation part 130 and abut against the non-through knife line 320 of the glass sheet 300, so that the glass sheet 300 is broken at the non-through knife line 320. By providing a movable top breaking part 120, the sheet breaking operation can be made more labor-saving, which is conducive to reducing the work intensity of the operator.

[0040] Further, refer to Figure 3 The air flotation portion 130 has a plurality of air blowing holes 131, and the plurality of air blowing holes 131 are arranged in an array on the air flotation portion 130. The plurality of air blowing holes 131 arranged in an array can provide a plurality of air blowing points on the entire air flotation portion 130, that is, provide a plurality of force application points for lifting the glass sheet 300, which is conducive to improving the uniformity of the force applied to the glass sheet 300 and reducing the possibility of damage to the glass sheet 300 due to uneven force applied when the glass sheet 300 is lifted by the airflow.

[0041] Further, refer to Figure 3 The sheet breaking workbench 100 further includes a top-breaking driving member 140, the output end of which is connected to the top-breaking portion 120 and is located below the top-breaking portion 120. The top-breaking driving member 140 can drive the top-breaking portion 120 to extend or retract relative to the air-floating portion 130. When driving the top-breaking portion 120 to extend relative to the air-floating portion 130, the top-breaking portion 120 can also provide a force that can break the glass sheet 300. The operator only needs to control the start and stop of the top-breaking driving member 140 to complete the sheet breaking action, which saves more effort and helps reduce the work intensity of the operator.

[0042] It should be noted that the position of the top-breaking drive member 140 in the figure is only for illustration. In actual use, in order to enable the horizontal and longitudinal top-breaking parts 120 to be independently controlled, each top-breaking part 120 is connected to a corresponding top-breaking drive member 140, so that each lifting action can only break the glass piece 300 at a cutting line extending along a straight line.

[0043] Further, refer to Figure 3 The sheet breaking workbench 100 further includes a blowing member 150, which is connected to the blowing hole 131. The blowing member 150 can provide an airflow capable of holding up the glass sheet 300 to the blowing hole 131. Specifically, the blowing member 150 can be a blower.

[0044] Further, refer to Figure 3 The sheet breaking workbench 100 also includes a buffer gas bin 160, which is located below the upper surface of the air flotation part 130. The buffer gas bin 160 is connected to all the blowing holes 131 of the same air flotation part 130, and the blowing member 150 is connected to the buffer gas bin 160. After the blowing member 150 is started, the airflow is first blown into the buffer gas bin 160. Since the resistance of the airflow diffusion in the buffer gas bin 160 is less than the resistance of blowing out from the blowing holes 131, the airflow generally fills the buffer gas bin 160 first, and then blows out from the multiple blowing holes 131. The provision of the buffer gas bin 160 can make the wind pressure of the airflow blown out of the multiple blowing holes 131 more consistent and more stable, which is conducive to improving the stability of the airflow holding up the glass sheet 300, and reducing the possibility of the glass sheet 300 being damaged due to uneven or unstable wind pressure when being held up by the airflow.

[0046] The glass cutting production line provided in the second aspect of the utility model adopts the anti-foolproof breaking device provided in the first aspect of the utility model. The anti-foolproof breaking device is provided with a display part 200 for displaying the cutting line pattern of the glass piece 300.
