[0021] Reference Figure 1-Figure 2A glass cutting and splitting device in this embodiment includes a machine platform 1 and a machine cover 2, a first material conveying module 3, a second material conveying module 4, a gantry 5, a pre-cutting laser system 6, and a splitting laser system 7 arranged on the machine platform 1. The first material conveying module 3, the second material conveying module 4, the gantry 5, the pre-cutting laser system 6, and the splitting laser system 7 are covered in the machine cover 2. The machine cover 2 is provided with a feed window 21 and a discharge window on both sides of the loading end and the unloading end. The two sides adjacent to the feed window 21 and the discharge window are also provided with openable and closable side doors to facilitate inspection and maintenance of the internal mechanism. The first material conveying module 3 and the second material conveying module 4 are arranged in parallel on the machine 1, and the gantry 5 vertically spans above the first material conveying module 3 and the second material conveying module 4. The pre-cutting laser system 6 and the split laser system 7 are respectively arranged on both sides of the gantry 5 through the linear module 8. Two detachable waste boxes are provided at the loading end of the machine, and the two waste boxes 9 are respectively located on one side of the first material conveying module 3 and the second material conveying module 4. The first material conveying module 3 and the second material conveying module 4 have the same structure, both of which include a Y-axis linear motor 31, a Y-axis guide rail 32, an adsorption platform 33 and an inclined ladder plate 34 arranged on the side of the adsorption platform 33. The inclined ladder plate 34 is arranged on the side of the waste box 9. The first material conveying module 3 and the second material conveying module 4 are used to carry and transport glass pieces. When the glass pieces are cut and split, the processed products are removed from the adsorption platform 33 at the unloading end, and the adsorption platform 33 returns to the loading end. The operator can use a brush or other tools to clean the waste remaining on the adsorption platform 33 from the loading window, and sweep the waste directly into the waste box 9 along the inclined ladder plate 34 next to it. After accumulating to a certain extent, it can be poured out in a unified manner. It is convenient and fast. The clean adsorption platform 33 can ensure the repeated positioning accuracy of each glass piece placement, and avoid the presence of waste particles. When the product is placed on the adsorption platform, it will cause deflection, warping, scratches, etc., which will affect subsequent operations.

[0022] Further references Figure 3 The adsorption platform 33 includes a base 331 and multiple unit platforms 332 detachably mounted on the base 331. Positioning bars 333 are provided on the unit platforms 332 to separate and position individual small-sized glass pieces. Both the base 331 and the unit platforms 332 possess adsorption capabilities, enabling them to securely hold glass products of varying sizes. Both also feature positioning points to ensure precise positioning of the first and second positioning cameras 63 and 73. The bottom surface of the base 331 is mounted on the Y-axis guide rail 32 via a slider. The Y-axis linear motor 31 drives the base 331 to perform reciprocating linear motion on the Y-axis guide rail 32.

[0023] In addition, a movable blocking net 211 is provided in the feed window 21 at the loading end of the corresponding machine 1. The blocking net 211 is a retractable structure, with a fixed end provided on the upper side of the feed window 21, and a movable end being retractable and snapped onto the bottom side of the feed window 21 when stretched out. The mesh cable of the blocking net 211 is unfolded to cover the entire feed window. After the movable end is released from the bottom side of the feed window 21, the mesh cable can be automatically retracted back to the fixed end, and the feed window 21 can be used for loading or cleaning. When loading or cleaning, open the blocking net 211 to load the material from the feed window 21. After completion, close the blocking net and start the machine. Safety first.

[0024] Furthermore, the gantry 5 includes two columns 52 and a crossbeam 51 mounted on the columns 52. Both the columns 52 and the crossbeam 51 are made of natural marble. The tabletop of the machine 1 is also made of natural marble, which provides good stability and improves the processing accuracy of the equipment. There are two sets of linear modules 8 with the same structure, which are located on opposite sides of the crossbeam 51 of the gantry. The pre-cutting laser system 6 and the split laser system 7 are each configured with one set. The linear modules 8 include an X-axis linear motion module 81 and a Z-axis linear motion module 82. The X-axis linear motion module 81 is located on the crossbeam 51 of the gantry 5, and the Z-axis linear motion module 82 is located on the X-axis linear motion module 81. The pre-cutting laser system 6 and the split laser system 7 are each located on their corresponding Z-axis linear modules 82.

[0025] The pre-cutting laser system 6 includes a picosecond laser 61, a pre-cutting head 62 matched with the picosecond laser 61, and a first positioning camera 63. The splitting laser system 7 includes a carbon dioxide laser 71, a heating cutting head 72 matched with the carbon dioxide laser 71, and a second positioning camera 73.

[0026] In this embodiment, the X-axis linear motion module 81 includes an X-axis linear motor and an X-axis guide rail, while the Z-axis linear motion module 82 is a ball screw linear module. The X-axis linear motor drives the Z-axis linear motion module to perform reciprocating linear motion on the X-axis guide rail. The pre-cutting head 62 and the first positioning camera 63 are mounted on the Z-axis linear motion module 82 via a connecting plate, and are driven by the Z-axis linear motion module 82 for synchronous lifting and lowering motion. The heated cutting head 72 and the second positioning camera 73 are also mounted on the Z-axis linear motion module 82 via a connecting plate, and are driven by the Z-axis linear motion module 82 for synchronous lifting and lowering motion. The picosecond laser 61 and the CO2 laser 71 are mounted on the gantry's crossbeam 51. In this embodiment, both the linear motors (X-axis and Y-axis) are equipped with linear scales.

[0027] Understandably, this works like this:

[0028] Loading: The suction platform 33 is on standby at the loading end. The screen 211 at the feed window 21 is opened, and the glass product to be cut is placed onto the suction platform 33 through the feed window. The suction platform 33 activates negative pressure to secure the glass product. For small glass products to be processed, the unit platform 332 can be pre-installed on the base 331. The glass product is then placed on the unit platform 332, and the positioning bars are used to roughly position and separate the products. For larger glass products to be processed, the unit platform 332 can be removed and the glass product can be placed directly on the base 331 for suction and securement.

[0029] Cutting: The Y-axis linear motor 31 drives the base 331 on the Y-axis guide rail 32 to the bottom of the pre-cutting laser system 6. The first positioning camera 63 accurately locates the glass product on the adsorption platform based on the positioning point on the adsorption platform 33. The X-axis linear motion module 81 and the Z-axis linear motion module 82 adjust the position of the pre-cutting head 62 to the cutting position. The picosecond laser 61 emits a laser beam, and the pre-cutting head 62 pre-cuts the glass product according to a pre-set program, forming a pre-cut line. During the pre-cutting process, the pre-cutting head 62 first operates on the glass product on one of the adsorption platforms 33. After completion, the product at that station continues to be transported to the operating area of the split laser system 7, and the pre-cutting head 62 directly translates to the glass product on the other adsorption platform 33 for operation.

[0030] Splitting: The second positioning camera 73 accurately locates the glass product transported from the previous workstation according to the positioning point on the adsorption platform 33, and adjusts the position of the heating cutting head 72 to the heating position through the X-axis linear motion module 81 and the Z-axis linear motion module 82. The carbon dioxide laser 71 emits a laser beam to heat the glass product located on the adsorption platform 33 along the pre-cutting line, so that it splits along the pre-cutting line under the impact of thermal stress, completing the cutting and splitting process.

[0031] Unloading: During the splitting process, the heated cutting head 72 first operates on the glass product on one of the adsorption platforms. After completion, the product of this station is transported to the unloading end, and the finished product is removed by a robot or manually. Then the adsorption platform 33 is sent back to the loading end, and the waste on the adsorption platform 33 is swept to the waste box 9 next to it by a manual or robotic arm. After cleaning, loading continues, and the heated cutting head 72 is directly translated to the other adsorption platform to operate the glass product. After completion, the unloading is also carried out, and the adsorption platform is returned to the loading end for cleaning and loading, realizing uninterrupted and continuous operation of the two stations.
