Description

Technical Field

[0001] This invention belongs to the field of glass sheet cutting technology, and particularly relates to a glass sheet positioning and cutting system. Background Technology

[0002] In existing laser cutting processes for glass sheets, the glass sheet is typically placed on a cutting table. The laser head moves laterally while the cutting table moves longitudinally, cutting rows of circular or rectangular glass units along a preset trajectory. All cut glass blocks are then removed together. However, this cutting and removal method has the following significant problems: to optimize the layout on the entire glass sheet and maximize material utilization, the cutting boundaries of adjacent glass blocks are usually designed to be extremely close, sometimes even sharing the same cutting path. This close-packed cutting method means that if a glass block is not removed promptly after cutting, the laser beam will again act on the edge area of ​​the already cut glass block when the next adjacent glass block is cut, causing secondary thermal impact or damage to its edge quality and reducing product consistency.

[0003] In addition, since a single cutting operation often involves dozens of glass blocks, the material is only retrieved after all units are completed. The material retrieval process takes a long time, thus extending the overall cutting cycle and restricting production efficiency.

[0004] Therefore, existing glass sheet cutting equipment suffers from the dual drawbacks of edge quality damage and low material handling efficiency when cutting glass sheets under the premise of optimizing the layout and maximizing material utilization. Further improvements are urgently needed to solve these problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a glass sheet positioning and cutting system, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present application provides the following technical solution: The present invention provides a glass sheet positioning and cutting system, including a cutting table, a laser cutting mechanism on the cutting table, a glass positioning frame and a support receiving frame on the cutting table, the glass positioning frame positioning the glass sheet and driving the glass sheet to slide back and forth along the cutting table to adjust the position of the glass sheet, and the support receiving frame supporting the position of the glass sheet to be cut and collecting the glass block after a single cut. The support receiving rack includes a chassis rotatably mounted above the cutting table. Four sets of reset connectors are arranged circumferentially on the chassis. Each reset connector has a detachable side baffle. Support bars are fixedly connected to the top of each side baffle. The four support bars naturally converge through their respective reset connectors to form a support area adapted to a single cutting path, used to support and limit the area to be cut of the original glass sheet. A central support plate is connected above the chassis via a lifting assembly. The central support plate is located within the four support bars. The four side baffles and the central support plate together form an upward-opening collection cavity for collecting glass blocks. The lifting assembly is equipped with a drive assembly for driving the four support bars to expand outwards.

[0007] According to an advantageous embodiment, the laser cutting mechanism includes two first guide rods fixedly disposed on the upper side of the cutting table and symmetrically arranged on the left and right. The two first guide rods are slidably connected to a rectangular mounting frame. A first slide rail is fixedly disposed on the front side of the upper frame of the mounting frame. A first linear motor is disposed on the first slide rail. A laser cutter is fixedly disposed on the first linear motor. A first cylinder is also fixedly disposed on the cutting table. The telescopic end of the first cylinder is fixedly connected to the lower frame of the mounting frame.

[0008] According to an advantageous embodiment, the glass positioning frame includes two second guide rods fixedly disposed on the upper side of the cutting table and symmetrically arranged on the left and right. A slide plate is slidably disposed between the two second guide rods. A negative pressure positioning platform is fixedly disposed on the upper side of the slide plate. A positioning strip with scale is fixedly disposed on the negative pressure positioning platform. A second cylinder is also disposed on the cutting table. The telescopic end of the second cylinder is fixedly connected to the slide plate.

[0009] According to an advantageous embodiment, a U-shaped carriage is fixedly installed on the upper side and near the rear side of the cutting table, and a second linear motor is installed on the horizontal section of the U-shaped carriage. The second linear motor is fixedly connected to the chassis.

[0010] According to an advantageous embodiment, the chassis has four grooves along its circumference, and a third guide rod is fixedly installed in each groove. The reset connector includes a connecting seat slidably disposed on the surface of the third guide rod. A reset spring is sleeved on the surface of the third guide rod. The two ends of the reset spring are fixedly connected to the corresponding connecting seat and the side wall of the corresponding groove, respectively. The connecting seat is connected to the side stop bar.

[0011] According to an advantageous embodiment, a guide plate is fixedly connected to the upper side of the connecting seat, a socket is fixedly provided on the upper side of the guide plate, a slot is provided on the upper side of the socket, and the lower end of the side stop bar is inserted into the slot and fixedly connected by bolts.

[0012] According to an advantageous embodiment, the lifting assembly includes a lifting screw rotatably disposed in the center of the chassis. A connecting sleeve is threadedly connected to the upper end of the lifting screw, and the connecting sleeve is fixedly connected to a central support plate. A fourth guide rod is also fixedly disposed on the chassis. A guide plate is fixedly disposed on the peripheral sidewall of the connecting sleeve near its lower end, and the guide plate is slidably connected to the fourth guide rod. A motor is fixedly disposed on the lower side of the chassis, and the output shaft of the motor is fixedly connected to the lower end of the lifting screw.

[0013] According to an advantageous embodiment, the drive assembly includes a drive disk fixedly disposed on the surface of the smooth section at the lower end of the lifting screw. The drive disk has four symmetrically distributed sliding holes along its circumference. An adjusting screw is rotatably disposed in the sliding holes. A drive plate is threadedly connected to the adjusting screw. A drive wheel is rotatably disposed at the end of the drive plate away from the lifting screw. The drive wheel rotates with the lifting screw and abuts against the guide disk, thereby pushing the guide disk to drive the connecting seat to slide radially along the chassis.

[0014] Compared with existing technologies, the glass sheet positioning and cutting system provided in this invention has the following advantages: In this invention, after a single glass sheet is cut, the support receiving rack moves downward and controls the four support bars to expand synchronously, causing the glass sheet to automatically fall into the collection chamber. Then, when cutting adjacent glass sheets, the laser beam no longer acts on the edges of the already cut glass sheets, thus eliminating secondary thermal effects on the edges. Finally, the support receiving rack and the laser cutting mechanism move synchronously to the next station, achieving continuous operation of cutting and collecting glass sheets in most areas. Only when cutting the remaining small portion of the glass sheet located at the negative pressure positioning table is the spacing appropriately increased to avoid damage caused by failure to collect. Compared to the quality and efficiency problems caused by the original method of unifying material collection after all cutting is completed, this invention can simultaneously improve cutting quality and efficiency.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will now be described in further detail.

[0029] Please refer to the following: Figures 1-3A glass sheet positioning and cutting system includes a cutting table 1, a laser cutting mechanism 2 on the cutting table 1, a glass positioning frame 3 and a support receiving frame 4 on the cutting table 1.

[0030] In practice, the glass positioning frame 3 uses vacuum adsorption to position the glass sheet 200 locally below its front edge, thus suspending the area of ​​the glass sheet 200 to be cut. Figure 5 As shown. Simultaneously, the support receiving rack 4 moves to directly below the area of ​​the glass sheet 200 to be cut, supporting the area and preventing chipping during cutting due to loss of support. Then, laser cutting is performed by the laser cutting mechanism 2, which can move forward, backward, left, and right. After cutting, the cut glass block 300 is automatically collected by the support receiving rack 4. Then, the support receiving rack 4 and the laser cutting mechanism 2 move horizontally to the lower cutting area for repeated cutting. After one row of cuts is completed, the glass positioning rack 3 moves the glass sheet 200 back and forth along the cutting table 1 to adjust it to the next row for repeated cutting.

[0031] See Figures 1-3 The laser cutting mechanism 2 includes two first guide rods fixedly mounted on the upper side of the cutting table 1 and symmetrically arranged on both sides. The two first guide rods are slidably connected to a rectangular mounting frame 21. A first slide rail 22 is fixedly mounted on the front side of the upper frame of the mounting frame 21. A first linear motor 23 is mounted on the first slide rail 22, and a laser cutter 24 is fixedly mounted on the first linear motor 23. A first cylinder 25 is also fixedly mounted on the cutting table 1, and the telescopic end of the first cylinder 25 is fixedly connected to the lower frame of the mounting frame 21. The first cylinder 25 drives the mounting frame 21 to move back and forth along the first guide rods, while the first linear motor 23 also drives the laser cutter 24 to move laterally left and right, enabling the laser cutter 24 to move back, forth, left, and right for laser cutting.

[0032] See Figure 1 and Figure 2 The glass positioning frame 3 includes two second guide rods fixedly mounted on the upper side of the cutting table 1 and symmetrically arranged on the left and right. A slide plate 31 is slidably mounted between the two second guide rods. A negative pressure positioning table 32 is fixedly mounted on the upper side of the slide plate 31. A positioning strip 33 with scale is fixedly mounted on the negative pressure positioning table 32. A second cylinder 34 is also mounted on the cutting table 1. The telescopic end of the second cylinder 34 is fixedly connected to the slide plate 31.

[0033] Multiple negative pressure holes are formed on the horizontal surface of the negative pressure positioning platform 32. Each negative pressure hole can be connected to an external negative pressure device to generate independent negative pressure for negative pressure adsorption of the glass sheet 200. After the glass sheet 200 is placed on the horizontal surface of the negative pressure positioning platform 32, the operator uses the positioning strip 33 to center the glass sheet 200 and fix it by negative pressure adsorption. During the subsequent cutting process, the second cylinder 34 drives the slide plate 31 to move the negative pressure positioning platform 32 back and forth along the second guide rod to adjust the front and back position of the glass sheet 200.

[0034] See Figure 1 , Figure 4 , Figure 5 and Figure 6 To maximize the utilization rate of the glass sheet 200 while improving the cutting quality and efficiency of the glass block 300, the support receiving rack 4 includes a chassis 41 rotatably mounted above the cutting table 1. The chassis 41 has four sets of reset connectors 42 distributed circumferentially on it. Each reset connector 42 has a detachable side baffle 43. Support bars 44 are fixedly connected to the top of each side baffle 43. The four support bars 44 naturally converge through their respective reset connectors 42 to form a support area 5 adapted to the single cutting path, used to support and limit the area of ​​the glass sheet 200 to be cut. A central support plate 46 is connected above the chassis 41 via a lifting assembly 45. The central support plate 46 is located within the four support bars 44. The four side baffles 43 and the central support plate 46 together form an upward-opening collection cavity 6 for collecting the glass block 300. The space of the collection cavity 6 increases as the central support plate 46 moves downward. Figures 10-12 As shown. The lifting assembly 45 is provided with a drive assembly 47 for driving the four support bars 44 to expand outward.

[0035] In practical applications, when cutting a 5mm circular glass block 300, this solution uses an arc-shaped support bar 44. The support bar 44 can be replaced according to the shape of the glass block 300 being cut.

[0036] Initially, the four arc-shaped support bars 44, under the action of their respective reset connectors 42, can approach each other and all abut against the central support plate 46, forming a support area 5. The diameter of the central support plate 46 is smaller than the diameter of the preset glass block 300 to be cut. The support area 5 acts below the preset circular cutting path 100 of the glass block 300 to provide support, ensuring that there is sufficient support force below the glass block 300 during cutting, preventing the glass block 300 from chipping due to uneven force. Figure 9 and Figure 10 As shown.

[0037] After the laser cutter 24 completes the cutting along the cutting path, the cut glass block 300 is completely separated from the original glass sheet 200. However, due to the support of four arc-shaped support bars 44 below, the support bars 44 will not fall off. During the process of the laser cutter 24 adjusting to the next station, the central support plate 46 moves downward under the control of the lifting assembly 45, increasing the space of the collecting cavity 6 to ensure that it can completely accommodate the glass block 300. Figure 11 As shown. The lifting assembly 45 synchronously controls the four arc-shaped support bars 44 to expand outwards simultaneously via the drive assembly 47, causing all four arc-shaped support bars 44 originally supporting the glass block 300 to separate from the lower side of the glass block 300. Then, the glass block 300 slides down along the side baffles 43 into the collection chamber 6, where it is supported by the central support plate 46. The central support plate 46 moves downwards a distance greater than or equal to the thickness of the glass block 300 each time, ensuring a small height difference between each cut glass block 300 and the collected glass blocks 300 below, preventing damage due to excessive drop. Most glass blocks 300 fall into the collection chamber 6, composed of the four side baffles 43 and the central support plate 46, in this manner for stacking and collection. Figure 12 As shown.

[0038] Since the remaining glass sheet 200 is completely supported by the negative pressure positioning table 32, when the last row of glass blocks 300 on the glass sheet 200 is cut, the support receiving rack 4 remains stationary, and the laser cutter 24 moves above the negative pressure positioning table 32 to cut each glass block 300 in that area. During cutting, since the support receiving rack 4 cannot collect the last row of glass blocks 300 in time, in order to avoid damage to the adjacent glass blocks 300 in the last row during cutting, the spacing between adjacent glass blocks 300 is increased when cutting the remaining glass sheet 200 on the negative pressure positioning table 32. Only the last row of glass blocks 300 in the glass sheet 200 is cut by increasing the spacing between adjacent glass blocks 300.

[0039] During the entire glass sheet 200 cutting process, most of the glass blocks 300 are cut and collected simultaneously. This ensures that the edges of the previously cut glass blocks 300 are not damaged when cutting the next glass block 300, and also facilitates the subsequent collection of glass blocks 300 by the staff.

[0040] It should be noted that during the process of cutting glass blocks 300 from glass sheet 200, some waste material is generated during the collection of glass blocks 300. This waste material will slide off the surface of the support bar 44. A collection mechanism that moves with the support bar 4 can be installed on the outside of the support collection rack 4 to collect the waste material. The specific structure and working principle of this collection mechanism are conventional technical means for those skilled in the art, so they will not be described in detail in this solution.

[0041] See Figure 1 , Figure 2 and Figure 4 To facilitate the support of the receiving rack 4 and allow it to slide synchronously with the laser cutter 24 to adjust its cutting position, a U-shaped slide 7 is fixedly installed on the upper side of the cutting table 1, near the rear. A second linear motor 8 is installed on the horizontal section of the U-shaped slide 7, and the second linear motor 8 is fixedly connected to the chassis 41. The second linear motor 8 controls the horizontal sliding of the chassis 41 to follow the movement of the laser cutter 24.

[0042] See Figure 6 and Figure 7 To facilitate the closure of the four support bars 44 during cutting and the collection of the glass block 300 after cutting, the base 41 has four circumferential grooves. A third guide rod is fixedly installed in each groove. The reset connector 42 includes a connecting seat 421 slidably mounted on the surface of the third guide rod. A reset spring 422 is sleeved on the surface of the third guide rod. The two ends of the reset spring 422 are fixedly connected to the corresponding connecting seat 421 and the side wall of the corresponding groove, respectively. The connecting seat 421 is connected to the side stop 43. A guide plate 423 is fixedly connected to the upper side of the connecting seat 421. A socket 424 is fixedly installed on the upper side of the guide plate 423. A slot is opened on the upper side of the socket 424. The lower end of the side stop 43 is inserted into the slot and fixedly connected by bolts. The side baffle 43 is fixed on the corresponding connecting seat 421, so that the support bar 44 at the upper end of the side baffle 43 can slide radially along the chassis 41. Under normal conditions, the four side baffles 43 are brought together by their respective return springs 422 to support the glass block 300 to be cut. After cutting, the drive assembly 47 will push the four guide discs 423 to slide radially outward along the chassis 41, so that the four support bars 44 release the support of the glass block 300, thereby allowing the glass block 300 to fall smoothly onto the central support plate 46 directly below.

[0043] See Figure 4 , Figure 6 and Figure 7The lifting assembly 45 includes a lifting screw 451 rotatably mounted in the middle of the chassis 41. A connecting sleeve 452 is threadedly connected to the upper end of the lifting screw 451. The connecting sleeve 452 is fixedly connected to the central support plate 46. A fourth guide rod is also fixedly mounted on the chassis 41. A guide plate 453 is fixedly mounted on the peripheral wall of the connecting sleeve 452 near its lower end, and the guide plate 453 is slidably connected to the fourth guide rod. A motor (not shown in the figure) is fixedly mounted on the lower side of the chassis 41, and the output shaft of the motor is fixedly connected to the lower end of the lifting screw 451. The motor drives the lifting screw 451 to rotate, causing the connecting sleeve 452 to move downwards under the limitation of the fourth guide rod, thereby causing the central support plate 46 to move downwards.

[0044] See Figure 7 and Figure 8 The drive assembly 47 includes a drive disk 471 fixedly mounted on the surface of the lower end of the smooth rod section of the lifting screw 451. The drive disk 471 has four symmetrically distributed sliding holes along its circumference. An adjusting screw 472 is rotatably mounted within each sliding hole. A drive plate 473 is threadedly connected to the adjusting screw 472. A drive wheel 474 is rotatably mounted at the end of the drive plate 473 away from the lifting screw 451. The drive wheel 474 rotates with the lifting screw 451 and abuts against the guide disk 423, thereby pushing the guide disk 423 to drive the connecting seat 421 to slide radially along the chassis 41. When the size of the cut glass block 300 is different, the position of the support bar 44 is different. The length of the drive plate 473 extending along the chassis 41 needs to be adjusted by adjusting the adjusting screw 472 to ensure that when the drive disk 471 drives the drive wheel 474 to rotate, it always abuts against the guide disk 423 and pushes the guide disk 423 to slide radially along the chassis 41.

[0045] Specifically, when the motor drives the lifting screw 451 to rotate and control the central support plate 46 to move downward, the lifting screw 451 drives the drive disk 471 to rotate, thereby causing the four drive plates 473 on the drive disk 471 to drive their respective drive wheels 474 to rotate. After rotating a certain angle, the four drive wheels 474 can abut against the corresponding guide disk 423, thereby pushing the connecting seat 421 on the guide disk 423 to slide radially along the chassis 41, causing the four support bars 44 to open. This allows the glass block 300 cut from the glass disc to fall onto the central support plate 46, which has moved downward a certain distance, after losing the support of the support bars 44. This expansion continues multiple times as the lifting screw 451 rotates until the central support plate 46 moves downward a certain distance and then stops.

[0046] It should be noted that, in order to avoid the problem that the drive wheel 474 would come into contact with the corresponding guide plate 423 after the lifting screw 451 stops rotating, thus preventing the support bar 44 from resetting, a pressure sensor can be installed in the rotating groove connecting the central shaft of the drive wheel 474 and the drive plate 473. This sensor can detect the pressure of the drive wheel 474 and send it to an external controller for analysis and judgment, ensuring that the pressure of the drive wheel 474 is below a threshold after the lifting screw 451 stops rotating, which means that the drive wheel 474 and the corresponding guide plate 423 are not in contact.

[0047] The entire cutting and positioning system operates as follows: First, the operator places the glass sheet 200 on the negative pressure positioning table 32. After centering and fixing with the assistance of the positioning strip 33, a small portion of the front of the glass sheet 200 rests on the negative pressure positioning table 32, while the majority remains suspended. At this point, the support area 5 formed by the four support strips 44 supports the glass sheet 200 at the cutting position. Then, the laser cutter 24 performs laser cutting on the glass sheet 200 at the preset position. After cutting, the laser cutter 24 moves to the next station. During this process, the cut glass pieces 300 are collected through the collection cavity 6 in the support and receiving rack 4, and then the laser cutter 24 moves to the next station below the glass sheet 200 for repeated support and collection.

[0048] For the portion of the original glass sheet 200 remaining on the negative pressure positioning stage 32, the laser cutter 24 moves directly above the stage 32, sacrificing some material from the last row of the original glass sheet 200. It cuts by widening the spacing between adjacent glass blocks 300 to ensure the cutting quality of each glass block 300. All the glass blocks 300 cut in the last row are then manually collected and sorted.

[0049] In summary, this solution employs a close-packed cutting and simultaneous collection method in the main area when cutting the 200mm glass sheet. Only when cutting the last row (located above the negative pressure positioning stage 32) is the spacing appropriately widened to avoid damage caused by the inability to collect the glass. This approach balances material utilization with the cutting quality of each piece of glass, achieving a balance between efficiency and quality.
