With the rapid development of related industries, higher and higher requirements are placed on the processing accuracy and production efficiency of large-size glass. Among them, cutting large-size glass into small-size glass that meets the needs of subsequent processing is one of the key processes.

Currently, manual handheld spray guns are used for cleaning, which is inefficient, time-consuming and labor-intensive. Second, the glass needs to be fixed after placement. Existing devices mostly rely on vacuum adsorption, but the vacuum device needs to be manually opened, which increases the manual intervention link and makes the operation cumbersome. The fixing effect may also be affected by operational delays or errors, which is not conducive to ensuring cutting quality. Summary of the Invention

Example 2

[0042] Reference Figure 2-Figure 15 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the positioning member 23 includes a guide groove 23-1 opened on one side of the top of the slope block 22, a threaded rod 23-2 is threadedly connected to one side of the slope block 22, one side of the threaded rod 23-2 passes through the slope block 22 and is rotatably connected to the inner cavity of the guide groove 23-1, the surface of the threaded rod 23-2 is threadedly connected to the positioning plate 23-3, and a scale 23-4 is provided on the other side of the top of the slope block 22.

[0044] The guide groove 23-1 provides guidance for the movement of the positioning plate 23-3; and the threaded rod 23-2 is threadedly connected to one side of the slope block 22, one end of which passes through the slope block 22 and is rotatably connected to the inner cavity of the guide groove 23-1. This design allows the user to easily adjust the position of the positioning plate 23-3 in the guide groove 23-1 by rotating the threaded rod 23-2; in actual operation, the user can flexibly adjust the position of the positioning plate 23-3 according to the size of the glass and the setting of the cutting module 13 to position the glass; at the same time, the scale 23-4 set on the other side of the top of the slope block 22 provides an intuitive reference for the position of the glass placement, and ensures the consistency of each glass placement and cutting by cooperating with the positioning plate 23-3.

[0045] Specifically, the support member 35 includes a support rod 35 - 1 fixedly connected to the surface of the rotating shaft 33 , and a support groove 35 - 2 is formed on the top of the workbench 21 and cooperates with the support rod 35 - 1 .

[0046] When the cleaning roller 34 is performing cleaning work, the rotating shaft 33 will drive the cleaning roller 34 to rotate. At this time, the support rod 35-1 plays a supporting and limiting role in the support groove 35-2; it can effectively prevent the rotating shaft 33 from shaking or deflecting during the rotation process, ensuring that the cleaning roller 34 always maintains a stable working state and improves the cleaning effect.

[0047] Specifically, the collecting member 37 includes a piston rod 37-1 fixedly connected to the side of the connecting shaft 24 away from the slope block 22, the side of the piston rod 37-1 away from the connecting shaft 24 is slidably connected to the piston cylinder 37-2, the piston cylinder 37-2 is fixedly connected to the bottom of the workbench 21, the surface of the piston cylinder 37-2 is connected to the hose 37-3, the side of the hose 37-3 away from the piston cylinder 37-2 is connected to the intermediate frame 37-4, the inner cavity of the intermediate frame 37-4 is fixedly connected to the filter cover, and cooperates with the hose 37-3, the top of the intermediate frame 37-4 is fixedly connected to the collecting frame 37-5, and the surface of the collecting frame 37-5 is provided with a collecting hole 37-6.

[0048] When the connecting shaft 24 moves due to the movement of the slope block 22, it drives the piston rod 37-1 to slide in the piston cylinder 37-2, thereby changing the pressure in the piston cylinder 37-2; the hose 37-3 connected to the surface of the piston cylinder 37-2 transmits the pressure change to the intermediate frame 37-4, causing a negative pressure to be generated in the intermediate frame 37-4; the intermediate frame 37-4 is fixedly connected to the inner cavity of the intermediate frame 37-4, which can effectively filter dust and other impurities and prevent them from entering the hose 37-3, thereby ensuring the smooth flow of airflow within the device; the collection frame 37-5 fixedly connected to the top of the intermediate frame 37-4 has a collection hole 37-6 on its surface. Under the action of negative pressure, the collection hole 37-6 generates suction, which draws fine impurities such as dust floating on the cleaning workbench 21 into the collection frame 37-5 and then into the intermediate frame 37-4. This effectively collects fine impurities generated during the cleaning process, prevents the spread of impurities in the working environment, reduces interference with subsequent cutting work, and also helps to keep the working area clean and hygienic, thereby improving the overall operating efficiency of the device.

[0049] Specifically, the collection frame 37-5 is fixedly connected to the bottom of the slope block 22, a first one-way valve 37-7 is arranged between the intermediate frame 37-4 and the collection frame 37-5, a storage frame 37-8 is fixedly connected to the bottom of the intermediate frame 37-4, a second one-way valve 37-9 is arranged between the storage frame 37-8 and the intermediate frame 37-4, a filter tip 37-10 is threadedly connected to one side of the storage frame 37-8 close to the piston cylinder 37-2, and the other side of the storage frame 37-8 is connected to the third one-way valve 37-11.

[0050] When the collecting frame 37-5 sucks the impurities into the intermediate frame 37-4 under the action of negative pressure, the first one-way valve 37-7 prevents the impurities from moving from the intermediate frame 37-4 to the collecting frame 37-5 after the suction is completed, ensuring that the impurities are stably collected in the intermediate frame 37-4; and the storage frame 37-8 fixedly connected to the bottom of the intermediate frame 37-4 is used to store the collected impurities for a long time; wherein the second one-way valve 37-9 provided between the storage frame 37-8 and the intermediate frame 37-4, when the piston rod 37-1 moves in the opposite direction to make the pressure in the intermediate frame 37-4 It opens when the force increases, and the fine impurities in the intermediate frame 37-4 are discharged into the storage frame 37-8; and the side of the storage frame 37-8 close to the piston cylinder 37-2 is threadedly connected to a filter tip 37-10, which can perform secondary filtration on the impurities discharged into the storage frame 37-8 and filter the fine impurities in the storage frame 37-8; the other side of the storage frame 37-8 is connected to a third one-way valve 37-11, which is convenient for cleaning the storage frame 37-8 by connecting an air gun and using gas to discharge fine impurities from the threaded hole connected to the filter tip 37-10.

[0051] Specifically, one side of the surface of the piston rod 37-1 is slidably connected to a reset plate 37-12, the bottom of the reset plate 37-12 is fixedly connected to the workbench 21, and the other side of the surface of the piston rod 37-1 is sleeved with a first spring 37-13, the side of the first spring 37-13 away from the reset plate 37-12 is fixedly connected to the connecting shaft 24, and the other side of the first spring 37-13 is fixedly connected to the reset plate 37-12.

[0052] When the connecting shaft 24 moves and drives the piston rod 37-1 to slide in the piston cylinder 37-2, the first spring 37-13 is compressed to store elastic potential energy; after the glass cutting is completed, when the workbench 21 needs to be cleaned for a second time and the collected impurities need to be discharged into the storage frame 37-8, the first spring 37-13 releases the elastic potential energy, pushing the connecting shaft 24 to move in the opposite direction, thereby driving the piston rod 37-1 to move in the opposite direction in the piston cylinder 37-2; the existence of this reset mechanism realizes the automation and cyclicality of the working process of the collecting member 37, and there is no need for manual operation to reset the piston rod 37-1, which reduces manual intervention and improves the working efficiency and stability of the device.

[0054] When the glass drives the lower pressure plate 40-2 to move, the second driving shaft 40-3 fixedly connected to the bottom of the lower pressure plate 40-2 moves accordingly, and the second spring 40-4 sleeved on the surface of the second driving shaft 40-3 plays a buffering role; and the bottom of the second driving shaft 40-3 passes through the embedded groove 40-1 and is slidably connected to the second driving seat 40-5, and the second slider 40-6 fixedly connected to one side of the second driving shaft 40-3 cooperates with the second sliding groove 40-7 opened on the surface of the second driving seat 40-5. When the lower pressure plate 40-2 is pressed down, the second driving shaft 40-3 drives the second slider 40-6 to slide in the second sliding groove 40-7, thereby causing the second driving seat 40-5 to rotate. The second driving seat 40-5 is moved; thereby, the rotating disk 40-8 fixedly connected to the surface of the second driving seat 40-5 rotates accordingly, and the limiting rod 40-10 slidably connected in the limiting groove 40-9 opened on the surface of the rotating disk 40-8, when the rotating disk 40-8 rotates, the limiting groove 40-9 is used to drive the limiting rod 40-10 and the blocking plate 40-11 fixed on one side thereof to move, so that the blocking plate 40-11 is away from the vacuum suction head 39, thereby turning on the vacuum suction head 39 to adsorb and fix the glass; and the trigger part 40-12 provided at the bottom of the lower pressure plate 40-2 can trigger the vacuum generator 40-121 to start after the blocking plate 40-11 moves, thereby realizing the adsorption of the glass.

[0055] Specifically, the top of the rotating disk 40-8 is fixedly connected to the limiting cylinder 40-13, the top of the limiting cylinder 40-13 is rotatably connected to the workbench 21, the surface of the limiting rod 40-10 is slidably connected to the fixing plate 40-14, and the top of the fixing plate 40-14 is fixedly connected to the workbench 21.

[0056] The top of the limiting cylinder 40-13 is rotatably connected to the workbench 21, providing stable support and guidance for the rotation of the rotating disk 40-8, preventing the rotating disk 40-8 from shaking or offsetting during rotation, and ensuring that the sealing plate 40-11 can accurately move according to the predetermined trajectory to achieve the sealing and opening of the vacuum suction head 39; and the movement of the limiting rod 40-10 is further limited and guided by the fixed plate 40-14, ensuring that the limiting rod 40-10 slides smoothly in the limiting groove 40-9, thereby making the movement of the sealing plate 40-11 more stable and reliable.

[0057] Specifically, the trigger part 40-12 includes a vacuum generator 40-121 fixedly connected to the bottom of the vacuum suction head 39, a first connection electrode 40-122 fixedly connected to the bottom of the lower pressing plate 40-2, and a second connection electrode 40-123 fixedly connected to the bottom of the inner cavity of the embedded groove 40-1.

[0058] When the glass is placed on the lower pressing plate 40-2 and the lower pressing plate 40-2 is moved into the embedded groove 40-1, the first connecting electrode 40-122 moves downward accordingly. When the first connecting electrode 40-122 contacts the second connecting electrode 40-123, a circuit path is formed, thereby triggering the vacuum generator 40-121 to start; after the vacuum generator 40-121 is started, the vacuum suction head 39 starts to work and adsorbs and fixes the glass, thereby realizing the automated association between glass placement and vacuum adsorption and fixation, reducing manual operation links and improving work efficiency.

[0059] Specifically, one side of the workbench 21 is slidably connected to a slide rod 40 - 124 , and one side of the slide rod 40 - 124 passes through the workbench 21 and extends into the embedded groove 40 - 1 .

[0060] After the glass is cut, when the glass needs to be removed, the sliding rod 40-124 is pushed to enter between the first connecting electrode 40-122 and the second connecting electrode 40-123, thereby cutting off the circuit path and turning off the vacuum generator 40-121; at this time, the vacuum suction head 39 stops working, and the user can smoothly remove the glass.

[0061] Working principle: When cutting large-size glass, the user first adjusts the positioning member 23 according to the specific size of the glass and the setting of the cutting module 13; by rotating the threaded rod 23-2, the positioning plate 23-3 slides smoothly in the guide groove 23-1, thereby achieving position control of the positioning plate 23-3; and by cooperating with the scale 23-4, the current glass and subsequent glasses are positioned, providing a solid guarantee for cutting consistency. Then, the user places the glass steadily on the top of the slope block 22; since the top of the slope block 22 is designed with a specific slope, the gravity of the glass will cause the slope block 22 to move; during this movement process, the slope block 22 drives the connecting shaft 24 and the pushing block 24-1 fixed on the connecting shaft 24 to move synchronously; when the pushing block 24-1 contacts the slope of the abutment plate 25, the abutment plate 25 is pushed, driving the first drive shaft 26 to move; during this period, the first slider 28 slides along a predetermined trajectory in the first slide groove 29, thereby driving the first drive seat 27 to rotate; the rotation of the first drive seat 27 in turn drives the first gear 31 fixed thereto to rotate synchronously, and since the first gear 31 and the second gear 32 are meshed with each other, the second gear 32 rotates accordingly, causing the rotating shaft 33 fixed to the inner cavity of the second gear 32 to rotate 180 degrees; the rotation of the rotating shaft 33 finally drives the cleaning roller 34 fixed on its top to clean impurities on the top of the workbench 21, effectively solving the problem that the existing workbench 21 needs to be cleaned manually. At the same time, during the movement of the connecting shaft 24, the piston rod 37-1 moves accordingly and slides in the piston cylinder 37-2; in this process, the first spring 37-13 is compressed, and the pressure in the piston cylinder 37-2 changes, which is transmitted to the intermediate frame 37-4 through the hose 37-3, so that a negative pressure is generated in the intermediate frame 37-4; under the action of the negative pressure, the collecting frame 37-5 and the collecting hole 37-6 generate a strong suction force, which can collect the floating fine impurities such as dust generated during the cleaning process into the intermediate frame 37-4; due to the presence of the first one-way valve 37-7, after the suction ends, the dust will not flow back from the intermediate frame 37-4 to the collecting frame 37-5, thereby ensuring the stability of impurity collection. As the glass descends, the glass will drive the lower pressure plate 40-2 to move downward and compress the second spring 40-4, which plays a good buffering role; when the lower pressure plate 40-2 moves, it drives the second drive shaft 40-3 to move, causing the second slider 40-6 to slide in the second slide groove 40-7, and then the second drive seat 40-5 to rotate, driving the rotating disk 40-8 to rotate; at this time, under the action of the limit groove 40-9, the limit rod 40-10 and the sealing plate 40-11 will move, so that the sealing plate 40-11 is away from the vacuum suction head 39; this design is to avoid the cleaning roller 34 from sweeping impurities into the vacuum suction head 39 during cleaning, causing blockage. As the lower pressing plate 40-2 enters the embedding groove 40-1, the first connecting electrode 40-122 and the second connecting electrode 40-123 come into contact, triggering the vacuum generator 40-121 to start, and the vacuum suction head 39 begins to absorb and fix the glass so that subsequent cutting work can proceed smoothly. When the glass cutting is completed, the user pushes the slide bar 40-124 to make it enter between the first connecting electrode 40-122 and the second connecting electrode 40-123, cutting off the circuit, turning off the vacuum generator 40-121, and stopping the vacuum suction head 39 from working. The user can then take out the glass. At this time, the second spring 40-4 drives the lower pressure plate 40-2 to reset, thereby driving the relevant components to move, causing the blocking plate 40-11 to move and block the vacuum suction head 39. At the same time, the first spring 37-13 resets, pushing the connecting shaft 24 to move in the reverse direction, driving the piston rod 37-1 to slide in the reverse direction in the piston cylinder 37-2, so that the vacuum suction head 39 can be removed. The pressure in the intermediate frame 37-4 increases, the second one-way valve 37-9 opens, and the fine impurities in the intermediate frame 37-4 are discharged into the storage frame 37-8; and the impurities are filtered through the filter tip 37-10. When it is necessary to clean the storage frame 37-8, the filter tip 37-10 can be threadedly removed, and the air gun can be connected to the third one-way valve 37-11 to use gas to discharge the impurities from the threaded hole connected to the filter tip 37-10; and, during the reverse movement of the connecting shaft 24, the relevant components will be driven to move, causing the cleaning roller 34 to rotate 180° in the opposite direction, and the workbench 21 will be cleaned for the second time, further ensuring the cleanliness of the workbench 21. Example 3

[0062] Reference Figure 11 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0063] Specifically, a through groove 40 - 1 a is formed at the bottom of the inner cavity of the embedding groove 40 - 1 .

[0064] During the process of cleaning the top of the workbench 21 by the cleaning roller 34, some impurities may be swept into the embedded groove 40-1; since a through groove 40-1a is provided at the bottom of the inner cavity of the embedded groove 40-1, these impurities entering the embedded groove 40-1 will be discharged in time through the through groove 40-1a, avoiding the accumulation of impurities in the embedded groove 40-1, further ensuring the cleanliness of the workbench 21, and reducing the impact of impurities on the normal operation of components such as the lower pressure plate 40-2.
