Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a glass cutting device. Background Technology

[0002] In the glass deep processing industry, glass cutting is a key early process. Its processing accuracy and efficiency directly determine the quality of subsequent processes such as edge grinding and tempering, and have a significant impact on the qualification rate of the final product. However, existing glass cutting equipment has many technical pain points in practical applications, making it difficult to meet the production needs of high precision and high efficiency.

[0003] Traditional equipment has significant shortcomings in the glass positioning process. Most rely on manual visual inspection or simple limiting structures, which cannot achieve precise positioning and secure locking of the glass. When the equipment vibrates slightly during operation, the glass is prone to slight displacement on the cutting table surface, causing deviations between the preset cutting trajectory and the actual cutting path. This results in dimensional errors or edge chipping defects, seriously affecting product quality. At the same time, cutting force control is another major weakness. Traditional pressure devices mostly provide a fixed force output and cannot be dynamically adjusted according to the material characteristics of the glass, such as thickness and hardness. When the cutting force is insufficient, the glass surface is prone to incomplete cutting, resulting in irregular fractures during subsequent breaking. On the other hand, excessive cutting force will cause local stress concentration in the glass, leading to direct breakage and significantly reducing the yield.

[0004] Therefore, developing a glass cutting device that can achieve precise positioning and locking, flexible adjustment of cutting direction and force, and efficient coordination of all stages has become the key to solving the current pain points in the industry and improving the quality and efficiency of glass processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The glass cutting device provided by this invention allows the glass to be cut to be placed on the cutting table surface manually or by a robotic arm. The positioning mechanism then precisely positions and locks the glass, keeping it relatively fixed to the cutting table. This operation effectively eliminates the interference that slight vibrations of the equipment may cause to the cutting action during subsequent cutting, providing a stable foundation for the entire cutting process. It reduces cutting deviations caused by glass displacement from the source and ensures the initial accuracy of the cutting.

[0018] During the process of the three-axis displacement mechanism driving the moving parts to move towards the glass surface, the rotating component first drives the rotating shaft to rotate, so that the cutting component at the bottom of the rotating shaft is adjusted to the cutting direction. This direction adjustment mechanism is flexible and efficient, and can quickly adapt to different cutting angles and path requirements. Whether it is straight cutting or irregular cutting, the orientation of the cutting component can be precisely adjusted to meet diverse glass processing needs and improve the versatility of the equipment.

[0019] Once the cutting component contacts the glass surface, the pressure application component can flexibly adjust the cutting force applied to the glass. Based on the actual conditions such as the thickness and material of the glass, the force can be precisely adjusted to avoid incomplete cutting due to insufficient force, and prevent the glass from breaking due to excessive force. This ensures that every cut meets the quality standards and effectively improves the product qualification rate.

[0020] Finally, the three-axis displacement mechanism drives the cutting component to move along the preset trajectory to complete the glass cutting operation. The entire equipment follows a coherent process of "positioning and locking, direction adjustment, force control, and trajectory cutting". The smooth connection between each link not only ensures the stability of the cutting process, but also allows for flexible adjustment of the cutting direction and force according to actual needs, which greatly improves the accuracy and efficiency of glass cutting and significantly optimizes the overall use effect.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-8 As shown, a glass cutting device according to an embodiment of the present invention includes a support 101. A cutting table 102 is fixedly installed on the top of the support 101. A movable member 103 is movably disposed above the cutting table 102. A mounting cavity 104 is formed in the movable member 103, and a movable plate 105 is movably installed in the mounting cavity 104. A mounting member 106 is fixedly installed on the lower surface of the movable plate 105, and the mounting member 106 penetrates the movable member 103. A through hole is formed in the mounting member 106, and a rotating shaft is movably installed in the through hole. 107, the end of the rotating shaft 107 is provided with a cutting component, the mounting cavity 104 is provided with a rotating component for driving the rotating shaft 107 to rotate, the mounting cavity 104 is also provided with a pressure application component for controlling the downward pressure applied to the glass by the cutting component during cutting, and also includes: a three-axis displacement mechanism, which is provided above the cutting table 102 for driving the moving part 103 to move along the x-axis, y-axis and z-axis; and a positioning mechanism, which is provided below the cutting table 102 for determining and locking the position of the glass to be cut.

[0032] The glass to be cut can be placed on the surface of the cutting table 102 manually or by a robotic arm. First, the positioning mechanism accurately positions and locks the glass, keeping it relatively fixed to the cutting table 102. This operation effectively eliminates the interference that slight vibrations of the equipment may cause to the cutting action during subsequent cutting, laying the foundation for stable cutting. Then, the three-axis displacement mechanism drives the moving part 103 to move towards the glass surface. During the movement, the rotating component first drives the rotating shaft 107 to rotate, adjusting the cutting component at the bottom of the rotating shaft 107 to the cutting direction. When the cutting component contacts the glass surface, the pressure component can flexibly adjust the cutting force applied to the glass by the cutting component to ensure that the force meets the cutting requirements. Finally, the three-axis displacement mechanism drives the cutting component to move along the preset trajectory to complete the glass cutting operation. Through the continuous process of "positioning and locking, direction adjustment, force control, and trajectory cutting", this equipment not only ensures the stability of the cutting process, but also flexibly adjusts the cutting direction and force according to actual needs, significantly improving the usage effect.

[0033] As one embodiment of the present invention, please refer to Figure 6 and Figure 7 The cutting assembly includes a cutting blade 108, which is made of a glass cutter specifically for cutting glass. The bottom end of the rotating shaft 107 has a slot, and the cutting blade 108 is fixed in the slot. Both the cutting blade 108 and the rotating shaft 107 have limiting holes on their outer sides that cooperate with the pin. When the cutting blade 108 is inserted into the slot at the bottom of the rotating shaft 107, it can be fixed by the pin. This design makes it easy to replace the cutting blade 108.

[0034] As one embodiment of the present invention, please refer to Figure 6 and Figure 7 The rotating assembly includes a stepper motor 201 fixedly installed on the inner wall of the top of the mounting cavity 104. The drive end of the stepper motor 201 is connected to a rotating drum 202. A block 203 is fixedly installed on the upper surface of the movable plate 105 and is located in the rotating drum 202. When it is necessary to adjust the cutting direction of the cutting blade 108, the stepper motor 201 can drive the rotating drum 202 to rotate, the rotating drum 202 drives the block 203 to rotate, and the block 203 can drive the rotating shaft 107 to rotate together, thereby realizing the direction adjustment operation of the cutting blade 108.

[0035] As one embodiment of the present invention, please refer to Figure 6 and Figure 7The pressure-applying component includes a side plate 302 fixedly installed on the inner wall of the mounting cavity 104. A movable rod 303 is movably installed in the side plate 302. A movable plate 305 is fixedly installed at the bottom end of the movable rod 303. A first spring 304 is sleeved on the outer side of the movable rod 303. One end of the first spring 304 is connected to the movable plate 305, and the other end of the first spring 304 is connected to the side plate 302. A cavity 306 is also provided in the movable member 103, and the cavity 306 is located above the mounting cavity 104. The top end of the movable rod 303 is located in the cavity 306, and a displacement plate 3 is fixedly installed at the top end of the movable rod 303. 07. A distance sensor 308 is also fixedly installed in the cavity 306 to detect the distance between the bottom of the cavity 306 and the displacement plate 307. A push rod 301 corresponding to the movable plate 305 is also fixedly installed on the upper surface of the movable plate 105. A limit ring 309 is also fixedly installed on the outer side of the movable rod 303, and the limit ring 309 is in contact with the upper surface of the side plate 302. When the moving part 103 moves downward until the cutting blade 108 contacts the glass surface, if the moving part 103 continues to move downward, the movable plate 105 in the mounting cavity 104 will move upward accordingly. At this time, the push rod 301 on the surface of the movable plate 105 will... Pushing the movable piece 305 upward causes the movable rod 303 to move upward synchronously, thereby compressing the first spring 304 on the outer side of the movable rod 303. The elastic potential energy of the first spring 304 is converted into a downward cutting force of the cutting blade 108 on the glass. The greater the compression, the stronger the cutting force. At the same time, the displacement plate 307 at the top of the movable rod 303 moves upward along with the movable rod 303. The distance sensor 308 at the top of the mounting cavity 104 detects the upward movement of the displacement plate 307 in real time. Since the upward movement of the displacement plate 307 is strictly proportional to the compression of the first spring 304, the displacement directly reflects the magnitude of the cutting force. By monitoring displacement data, the cutting force can be precisely controlled. When the displacement plate 307 reaches the preset upward movement, the downward movement of the moving part 103 is immediately stopped, so that the cutting force applied by the cutting blade 108 to the glass can be stabilized at the required value. This cutting force control mechanism, which is achieved through mechanical linkage and sensor monitoring, can not only make the cutting force change linearly with the spring compression, but also provide real-time feedback on the force through displacement data. This ensures that the cutting force can be flexibly adjusted according to the glass material, thickness and other requirements, effectively avoiding the problem of glass breakage due to excessive force or insufficient force affecting the cutting effect. The stability and accuracy of use are significantly improved.

[0036] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3The three-axis displacement mechanism includes a movable frame 401 slidably disposed on the outside of the cutting table 102. A servo motor 403 is fixedly mounted on the side wall of the movable frame 401, and an output gear 404 is fixedly mounted on the drive end of the servo motor 403. A mounting shaft 407 is also rotatably mounted on the side wall of the movable frame 401. A driven gear 406 is fixedly mounted on one end of the mounting shaft 407, and the driven gear 406 and the output gear 404 are connected by a transmission belt 405. A transmission gear 408 is fixedly mounted on the other end of the mounting shaft 407. A rack 402 is fixedly mounted on the wall, and the transmission gear 408 and the rack 402 are engaged. A first electric slide rail 409 is fixedly mounted on the outer wall of the movable frame 401, and a first slider 410 is slidably disposed in the first electric slide rail 409. A displacement block 411 is fixedly mounted on the outer wall of the first slider 410, and a second electric slide rail 412 is fixedly mounted on the outer wall of the displacement block 411, and a second slider 413 is slidably mounted in the second electric slide rail 412. A moving part 103 is fixedly mounted on the outer wall of the second slider 413. The output gear can be driven by the servo motor 403. When wheel 404 rotates, power is transmitted to driven gear 406 via transmission belt 405. Driven gear 406 then drives transmission gear 408 to rotate synchronously via mounting shaft 407. Since transmission gear 408 meshes with rack 402, rotational motion is converted into linear motion, thereby driving the moving frame 401 to move smoothly along the x-axis, realizing the position adjustment of moving part 103 on the x-axis. On the first electric slide rail 409 on the outer side of the moving frame 401, the first slider 410 can slide along the slide rail, driving moving part 103 along the y-axis via displacement block 411. The movement of the moving part 103 is completed by adjusting its y-axis displacement. At the same time, a second slider 413 is provided on the second electric slide rail 412 outside the displacement block 411. The sliding of the second slider 413 can directly drive the moving part 103 to rise and fall along the z-axis, thereby adjusting the z-axis position of the moving part 103. Through the coordinated movement of the x-axis, y-axis and z-axis, the moving part 103 can flexibly adjust its position in three-dimensional space, providing precise trajectory guidance for the cutting component, meeting the needs of various complex cutting paths, and greatly improving the flexibility and accuracy of the cutting operation.

[0037] As one embodiment of the present invention, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 8The positioning mechanism includes a third electric slide rail 502 arranged in a cross shape below the cutting table 102. A support frame 501 is fixedly installed on the side wall of the third slide rail. The top of the support frame 501 is fixedly connected to the lower surface of the cutting table 102. A third slider 503 is slidably installed in the third electric slide rail 502. A groove is provided on the top of the third slider 503, and a movable block 504 is movably installed in the groove. A horizontal plate 505 is fixedly installed on the top of the movable block 504. A sliding groove 506 is provided on the side wall of the horizontal plate 505, and a clamping plate 508 is slidably installed in the sliding groove 506. A second spring 507 is fixedly installed on the inner wall of the sliding groove 506. One end of 507 is connected to the end of the clamping plate 508. A movable opening 511 is provided on the surface of the cutting table 102, and the vertical portion of the clamping plate 508 is located within the movable opening 511. A distance measuring plate 510 is also fixedly installed on the surface of the cutting table 102. A distance sensor 509 is fixedly installed on the outer wall of the clamping plate 508 to detect the distance between the distance measuring plate 510 and the clamping plate 508. A locking module is also provided below the clamping plate 508 to lock its position. After the glass is placed on the surface of the cutting table 102, the positioning process is initiated. The third electric slide rail 502 drives the third slider 503 to move. The third slider 503 can... The movable block 504, which adjusts vertically, drives the horizontal plate 505 to move laterally, thereby causing the clamping plate 508 to move synchronously along the movable opening 511. During this process, the second distance sensor 509 monitors the distance change between the clamping plate 508 and the measuring plate 510 in real time, accurately capturing the position information of the clamping plate 508. When the vertical part of the clamping plate 508 contacts the glass, if the third slider 503 continues to move, the second spring 507 between the clamping plate 508 and the slide groove 506 will be gradually stretched. The elastic force of the second spring 507 ensures that the vertical part of the clamping plate 508 remains in close contact with the glass sidewall until the detection data of the second distance sensor 509 is reached. Once the value stabilizes and stops changing, the system determines that the glass has been reliably clamped and immediately stops the movement of the third slider 503. The value fed back by the distance sensor 509 can intuitively confirm the specific position of the glass on the cutting table 102, providing a basis for the accurate planning of the subsequent cutting trajectory. After positioning is completed, the locking module is activated and locks the position of the clamping plate 508, keeping the glass and the cutting table 102 relatively stationary. This design, through the combination of elastic clamping, real-time monitoring, and rigid locking, can not only avoid damage to the glass due to excessive clamping force, but also completely eliminate the risk of glass displacement during the cutting process, significantly improving the stability and accuracy of the cutting operation.

[0038] As one embodiment of the present invention, please refer to Figure 4 and Figure 5The locking module includes an electric telescopic rod 601 fixedly installed in the support frame 501. A support plate 602 is fixedly installed at the telescopic end of the electric telescopic rod 601, and the support plate 602 is located below the clamping plate 508. When it is necessary to lock the position of the clamping plate 508, the electric telescopic rod 601 is activated, and its telescopic end will drive the support plate 602 to move upward until the support plate 602 is tightly pressed against the bottom of the clamping plate 508. Through the rigid support and limitation of the clamping plate 508 by the support plate 602, the position of the clamping plate 508 can be quickly fixed, ensuring that the glass is stably clamped between the clamping plates 508, and avoiding glass displacement due to loosening of the clamping plates 508 during subsequent cutting. This locking method is simple to operate, responds quickly, and can effectively ensure the stability of the clamping state.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
