Description

Technical Field

[0001] The invention relates to the technical field of glass cutting, in particular to a positionable sliding cutting device for tempered glass processing. Background Art

[0002] Tempered glass is a glass with compressive stress on the surface, also known as strengthened glass. The glass is strengthened by tempering. Tempered glass is a safety glass. Tempered glass is actually a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc.

[0003] Sliding cutting is a method of cutting by sliding the blade against the object being cut. Specifically, it is a type of cutting technology that uses a sliding blade to cut glass, etc.

[0004] When existing glass sliding cutting equipment is sliding cutting glass, different thicknesses of glass often require different pressures to be applied to the glass cutter head for sliding cutting. The cutting depth required for thick glass is deeper than that for thin glass, which is convenient for breaking the glass and avoiding cracking. However, when sliding cutting glass of different thicknesses, it is currently necessary to manually adjust the position and pressure of the glass cutter head, which is time-consuming and has low efficiency in glass sliding cutting. In addition, during the sliding cutting process, when the sliding cutting groove on the glass does not meet the sliding cutting requirements, breaking the glass is likely to cause the glass to shatter.

When the distance track is a straight line, it means that the cutting depth of the glass is the same and the glass cutting is qualified. When the distance track has certain ups and downs, it means that the depth changes during the glass cutting process and the glass cutting is unqualified. Therefore, it can be intuitively detected whether the glass cutting meets the standards, and it is relatively simple to monitor the glass cutting. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the adjusting mechanism 4 includes an adjusting groove 30 arranged in the slide groove, an adjusting screw 31 is rotatably installed in the adjusting groove 30, an adjusting screw 31 is externally threadedly sleeved with an adjusting block 32, and the adjusting block 32 is slidably installed in the adjusting groove 30, a second motor 33 is fixedly installed outside the bottom plate 2, and a driving shaft of the second motor 33 rotates through the bottom plate 2. The plate 2 is coaxially fixedly connected with the adjusting screw 31, the upper end of the adjusting block 32 is fixedly connected with the slide plate 3, a support plate 5 is arranged above the slide plate 3, the support plate 5 and the slide plate 3 are fixedly connected by a fixing column 6, a plurality of fixed suction cups 7 are installed on the upper end of the support plate 5, it is worth mentioning that the plurality of fixed suction cups 7 are evenly distributed on the support plate 5 in an array, it should be noted that the fixed suction cups 7 and the positioning suction cups 9 are both negative pressure suction cups, a lifting plate 8 is arranged above the support plate 5, positioning suction cups 9 are fixedly installed at the four corners of the lower end of the lifting plate 8, and a glass cutter 10 is arranged below the lifting plate 8;

[0036] By setting the above technical features, when placing the glass, the glass to be cut is placed on the support plate 5, and a plurality of fixed suction cups 7 are installed on the support plate 5. The glass is adsorbed and fixed by the fixed suction cups 7. When adjusting the cutting position of the glass, the adjusting screw 31 is driven to rotate by the second motor 33, and the adjusting screw 31 drives the adjusting block 32 to move, and the adjusting block 32 drives the slide plate 3 to move. The slide plate 3 and the fixed column 6 connected thereto and the support plate 5 move synchronously, and the glass fixed on the support plate 5 by the fixed suction cups 7 move synchronously, and the cutting position of the glass can be adjusted.

[0037] After the glass position is adjusted, the glass cutter 10 and the positioning suction cup 9 are adjusted to the appropriate position, so a lifting mechanism 11 is set up to lift the lifting plate 8. The lifting mechanism 11 includes a lifting hole 12 penetrated between the two vertical plates 1, and first threaded rods 13 are vertically rotatably installed in the two lifting holes 12. Specifically, the external threads of the two first threaded rods 13 have the same rotation direction. A first motor 14 is fixedly installed on the upper end of the left vertical plate 1, and the output end of the first motor 14 is fixedly connected to the upper end of the first threaded rod 13. A through hole 15 is penetrated at the bottom of the vertical plate 1, and the lower end of the first threaded rod 13 is fixedly connected to the upper end of the first threaded rod 13. The end extends into the through hole 15, and the lower ends of the two first threaded rods 13 are connected by a transmission mechanism 16. It is worth mentioning that the transmission mechanism 16 includes two pulleys 34, and the two pulleys 34 are connected by a synchronous belt transmission. The two pulleys 34 are coaxially fixedly connected to the two first threaded rods 13 respectively, and a through hole matching the synchronous belt is provided on the bottom plate 2. The outer surface of the first threaded rod 13 in the lifting hole 12 is provided with a threaded block 17 through threaded rotation. The threaded block 17 is fixedly connected to the lifting plate 8, and the lifting mechanism 11 is used to adjust the overall position of the glass cutter 10 to the cutting position.

[0038] Through the above technical features, when the position of the glass cutter 10 is adjusted as a whole, one of the first threaded rods 13 is driven to rotate by the first motor 14, and the first threaded rod 13 drives the other first threaded rod 13 to rotate under the action of two pulleys 34. The two first threaded rods 13 drive the two threaded blocks 17 to rise and fall through the threads, and the two threaded blocks 17 drive the lifting plate 8 to rise and fall, and the lifting plate 8 drives the glass cutter 10 and the positioning suction cup 9 to rise and fall until the positioning suction cup 9 is adsorbed and fixed to the cut glass, and the glass cutter 10 reaches the predetermined position.

[0039] In the present invention, a cutting hole 18 is provided through the lifting plate 8, a moving block 19 is slidably installed in the cutting hole 18, a U-shaped plate 20 is slidably mounted on the lower side wall of the moving block 19, and it is worth mentioning that a distance sensor 39 is fixedly embedded at the lower end of the U-shaped plate 20. It should be noted that the distance sensor 39 detects the vertical distance between the distance sensor 39 and the glass, and the detected data is collected, processed, and converted into coordinate points, and then the coordinate points are drawn to form an image, so that whether the depth of glass cutting changes during the glass cutting process can be intuitively monitored:

[0040] It should be noted that, through the above steps, the collected distance data can be converted into visual images, which are intuitive to observe. Since data conversion into images is an existing technical means, it will not be described in detail.

[0041] In the present invention, the glass cutter 10 is fixedly mounted on the lower end of the U-shaped plate 20, and a fine adjustment mechanism 29 for finely adjusting the height of the glass cutter is provided on the lifting plate 8. It should be noted that the fine adjustment structure 29 includes a cavity 21 provided in one of the threaded blocks 17, a first threaded rod 13 is provided through the cavity 21, and a sliding sleeve 22 is provided outside the first threaded rod 13. It should be noted that, as Figure 8 The outer wall of the first threaded rod 13 is provided with a plurality of sliding grooves, and the inner wall of the sliding sleeve 22 is provided with a plurality of sliding blocks, and the sliding blocks are slidably installed in the sliding grooves. Both ends of the sliding sleeve 22 are rotatably connected to the inner wall of the cavity 21, and a rotating shaft 23 is rotatably installed in the cutting hole 18. One end of the rotating shaft 23 rotates through the lifting plate 8 and the threaded block 17 and extends to be arranged in the cavity 21. The left end of the rotating shaft 23 is coaxially fixedly connected with a toothed disc 36, and a gear 35 is coaxially fixedly connected outside the sliding sleeve 22. The gear 35 is meshed with the toothed disc 36. It should be noted that the gear ratio of the tooth groove on the toothed disc 36 to the tooth teeth of the gear 35 is much greater than one.

[0042] In the present invention, a transmission chamber 25 is provided in the moving block 19, the rotating shaft 23 passes through the transmission chamber 25 and is fixedly connected with a first bevel gear 37, a rotating sleeve 26 is slidingly sleeved outside the rotating shaft 23, and the two ends of the rotating sleeve 26 are rotatably connected with the inner side walls of the transmission chamber 25 respectively, a lifting cylinder 27 is fixedly connected in the middle of the U-shaped plate 20, and a third threaded rod 28 is sleeved on the inner thread of the lifting cylinder 27, and the upper end of the third threaded rod 28 extends into the transmission chamber 25 and is fixedly connected with a second bevel gear 38, and the first bevel gear 37 is meshed with the second bevel gear 38. A second threaded rod 40 is rotatably connected between the two threaded blocks 17, and the second threaded rod 40 is threadedly penetrated through the moving block 19, and a third motor 24 is fixedly connected to the side wall of one of the threaded blocks 17, and the driving shaft of the third motor 24 rotatably passes through the threaded block 17 and is coaxially fixedly connected with the second threaded rod 40. The transmission between the rotating sleeve 26 and the sliding sleeve 22 can fine-tune the position of the glass cutter 10 according to the thickness of the glass to be cut.

[0043] By setting the above technical features, after the glass is placed, while adjusting the overall position of the glass cutter 10, the rotation of the first threaded rod 13 will also drive the sliding sleeve 22 connected thereto to rotate, the sliding sleeve 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the rotating sleeve 26 connected thereto to rotate. Since the rotating sleeve 26 and the third threaded rod 28 are driven by the first bevel gear 37 and the second bevel gear 38, the rotating sleeve 26 drives the third threaded rod 28 to rotate, and the third threaded rod 28 is threadedly connected to the lifting cylinder 27. The lifting cylinder 27 is driven to rise and fall by the third threaded rod 28, and the lifting cylinder 27 drives the U-shaped plate 20 and the glass cutter 10 connected thereto to rise and fall, so that the glass cutter 10 can be fine-tuned until the positioning suction cup 9 is fixed to the glass to be cut. At this time, the glass cutter 10 reaches the cutting position. When the glass to be cut is cut, the second threaded rod 40 is driven to rotate by the third motor 41, and the second threaded rod 40 drives the moving block 19 threadedly connected thereto to move, and the moving block 19 drives the glass cutter 10 to move, and the glass cutter 10 can cut the glass.

[0044] It should be noted that when the thickness of the glass to be cut is thicker, the distance of fine-tuning the vertical position of the glass cutter 10 is shorter. At this time, the vertical distance between the lower end face of the glass cutter 10 and the lower end face of the positioning suction cup 9 is longer, and the cutting groove depth is deeper when the glass is cut; when the thickness of the glass to be cut is thinner, the distance of fine-tuning the vertical position of the glass cutter 10 is longer. At this time, the vertical distance between the lower end face of the glass cutter 10 and the lower end face of the positioning suction cup 9 is shorter, and the cutting groove depth is shallower when the glass is cut, and the glass can be automatically cut according to the thickness of the glass to be cut.

[0045] Working principle:

[0046] 1) Placing the glass: placing the glass to be cut on a support plate 5, on which a plurality of fixed suction cups 7 are mounted, and the glass is fixed by adsorbing the fixed suction cups 7;

[0047] 2) Adjust the glass to the position to be cut: the second motor 33 drives the adjusting screw 31 to rotate, the adjusting screw 31 drives the adjusting block 32 to move, the adjusting block 32 drives the slide plate 3 to move, the slide plate 3 and the fixed column 6 connected thereto and the support plate 5 move synchronously, and the glass fixed on the support plate 5 by the fixed suction cup 7 moves synchronously until it reaches a suitable position;

[0048] 3) Adjusting the height of the glass cutter 10: The first motor 14 drives one of the first threaded rods 13 to rotate, and the first threaded rod 13 drives the other first threaded rod 13 to rotate under the action of the two pulleys 34. The first threaded rod 13 drives the two threaded blocks 17 to rise and fall through the thread, and the two threaded blocks 17 drive the lifting plate 8 to rise and fall, and the lifting plate 8 drives the glass cutter 10 and the positioning suction cup 9 to rise and fall. At the same time, the rotation of the first threaded rod 13 will also drive the sliding sleeve 22 connected thereto to rotate. Since the rotating sleeve 26 and the third threaded rod 28 are driven by the first bevel gear 37 and the second bevel gear 38, the rotating sleeve 26 drives the third threaded rod 28 to rotate. Since the third threaded rod 28 is threadedly connected to the lifting cylinder 27, the third threaded rod 28 drives the lifting cylinder 27 to rise and fall, and the lifting cylinder 27 drives the U-shaped plate 20 connected thereto to rise and fall and the glass cutter 10 to rise and fall until the positioning suction cup 9 is adsorbed and fixed to the cut glass;

[0049] 4) Cutting the glass: The third motor 41 drives the second threaded rod 40 to rotate, the second threaded rod 40 drives the moving block 19 threadedly connected thereto to move, the moving block 19 drives the glass cutter 10 to move, and the glass cutter 10 can cut the glass.
