Description

Technical Field

[0001] This invention relates to the technical field of glass cover cutting, specifically a cutting device for processing mobile phone glass covers. Background Technology

[0002] Currently, in the manufacturing process of mobile phone glass covers, to improve processing efficiency and material utilization, a common practice is to cut large-area raw glass substrates. A large glass substrate is precisely cut into multiple individual glass cover plates of accurate dimensions to meet the needs of subsequent large-volume, standardized assembly. This production method of cutting large pieces into smaller ones is a fundamental step in achieving large-scale manufacturing of mobile phone cover plates.

[0003] However, existing cutting devices and processes for large raw material plates have certain limitations. First, conventional cutting methods typically involve a single cutting head moving sequentially along the complex closed contour of each cover plate. This cumbersome movement path hinders further improvements in cutting efficiency. Furthermore, this operating mode is not well-integrated with continuous automated production lines, affecting the consistency of production cycles. More importantly, during and after cutting, the internal stress of the glass substrate gradually releases, and changes in ambient temperature cause thermal expansion and contraction of the material. These two factors combined result in minute, unpredictable deformations in the dimensions of the cut glass cover plates. Because existing cutting devices lack effective online detection and real-time compensation mechanisms, they cannot eliminate or counteract the effects of this deformation during the cutting process. Consequently, the dimensional accuracy of the final product is difficult to control precisely, directly impacting product yield and consistency. Summary of the Invention

Specifically, the device achieves stable input of large raw material plates and efficient reversing conveying of strip raw material plates through the coordinated operation of the first and second conveyor components. Combined with the strip cutting component, it can quickly and accurately complete the initial processing of precisely dividing large plates into strip plates, effectively improving cutting efficiency and simplifying the cutting path. Furthermore, the adjustment component on the vertical platform can precisely drive the block cutting component to move along the length of the vertical platform, allowing the side trimming component and the transverse cutting component to sequentially perform side trimming and transverse cutting on the strip raw material plates. This results in the continuous and efficient production of multiple uniformly sized block glass cover plates from a single strip, avoiding the complex and lengthy single-piece detour path of the cutting head. This ensures smooth connection between the entire cutting operation and the rear conveyor, greatly improving the continuity of the production cycle.

[0016] 2. A first measuring device is installed at the junction of the horizontal and vertical platforms, and a second measuring device is installed at the end of the conveyor. The first measuring device can measure the actual width of the strip-shaped raw material plate after cutting in real time and use this data as the adjustment benchmark for the subsequent block cutting process; the second measuring device performs final dimensional verification on the final produced block glass cover and feeds the results back to the control system. Through this online monitoring and data interaction, the control system can accurately adjust the cutting width of the side trimming component in the block cutting assembly according to the actual deformation of the strip plate. This effectively compensates for dimensional fluctuations caused by stress release or changes in ambient temperature during the block cutting process, ensuring that the dimensions of the final block glass cover can still accurately meet the qualified standards after possible minor deformations. This fundamentally solves the problem of dimensional accuracy loss due to material deformation and significantly improves the product yield and consistency. Attached Figure Description

[0030] The feed limit plate 104 is fixed to the crossbeam 101 by bolts through a long slot, and can be adjusted and locked according to the actual width of the large raw material plate. The surface of the conveyor roller 204 is covered with an anti-slip rubber layer to increase the friction with the glass and prevent slippage.

[0031] The second conveying component 3 has the same structure as the first conveying component 2, but different in size and direction. The conveying directions of the second conveying component 3 and the first conveying component 2 are perpendicular to each other. A cutting limit plate 107 is provided at the top of the cross platform 101 on the side of the second conveying component 3 away from the first conveying component 2.

[0032] The installation method of the strip cutting limit plate 107 is the same as that of the feed limit plate 104. It is also an adjustable structure used to hold one end of the large raw material plate and provide a precise longitudinal positioning reference for the strip cutting assembly 4.

[0033] The slicing assembly 4 includes a first frame plate 401. A first one-way threaded rod 404 is rotatably connected longitudinally to the top of the first frame plate 401 on the side away from the first conveying assembly 2.

A first longitudinal cutting groove 108 is provided at the top of the longitudinal platform 102 at a position corresponding to the moving trajectory of the first longitudinal cutting machine 407.

[0034] The first support plate 401 is a portal frame structure, spanning across the horizontal platform 101. Its two ends are bolted to the bases on both sides of the platform 101, ensuring overall rigidity during cutting. The first telescopic component 402, the second telescopic component 406, the third telescopic component 607, and the fourth telescopic component 612 can all be high-precision pneumatic or electric cylinders, with built-in displacement sensors to achieve precise control of the downward pressure on the cutter wheel. A flexible rubber pad is attached to the bottom of the clamping plate 403 to prevent damage to the glass surface.

[0035] The adjustment assembly 5 includes a first base 501 and a second base 502 located on both sides of the top of the longitudinal platform 102. A second one-way threaded rod 503 is rotatably connected to the first base 501 along the longitudinal direction. A third driving member 504 is installed at one end of the first base 501. The output end of the third driving member 504 is connected to one end of the second one-way threaded rod 503. A second movable block 505 is threadedly connected to the second one-way threaded rod 503. A track rod 506 is longitudinally fixedly connected to the second base 502. A third movable block 507 is inserted and connected to the track rod 506. The cutting assembly 6 includes a second frame plate 601. The bottom ends of the two ends of the second frame plate 601 are respectively installed on the second movable block 505 and the third movable block 507.

[0036] The first base 501 and the second base 502 are both precision-machined metal blocks, fixed to the side of the longitudinal platform 102 by positioning pins and bolts. The track rod 506 is the guide rail in the precision linear guide pair, and the third movable block 507 is the corresponding slider. The two work together to ensure the straightness and stability of the movement of the cutting assembly 6.

[0037] The side-end trimming assembly 602 includes a bidirectional threaded rod 604 rotatably connected to one side of the top of the second frame plate 601 along the lateral direction, and two fourth movable blocks 606 symmetrically and threadedly connected to the bidirectional threaded rod 604. A fourth driving member 605 is installed at one end of the second frame plate 601, and the output end of the fourth driving member 605 is connected to one end of the bidirectional threaded rod 604. A third telescopic member 607 is vertically installed on the fourth movable block 606, and a second longitudinal cutter 608 is installed at the bottom end of the third telescopic member 607.

A fourth telescopic member 612 is vertically installed on the fifth movable block 611, and a transverse cutter 613 is installed at the bottom end of the fourth telescopic member 612.

[0038] The threads at both ends of the bidirectional threaded rod 604 are in opposite directions to enable the two fourth movable blocks 606 to move synchronously towards or away from each other. The second frame plate 601 is provided with linear guides that cooperate with the fourth movable blocks 606 and the fifth movable block 611 to guide their movement and withstand the lateral force during cutting.

[0039] Two second longitudinal cutting grooves 109 are symmetrically arranged at the center of the top of the longitudinal platform 102 along its width direction. Several transverse cutting grooves 110 are equally spaced at the center of the top of the longitudinal platform 102 along its length direction. The two ends of the transverse cutting grooves 110 are cross-shaped and staggered with the second longitudinal cutting grooves 109. A cutting limiting plate 105 is provided at the top of the longitudinal platform 102 outside the second longitudinal cutting grooves 109. The transverse cutting grooves 110 extend to the cutting limiting plate 105.

[0040] The second longitudinal cutting groove 109 and the transverse cutting groove 110 are both through grooves that penetrate the top plate of the longitudinal table 102, used to accommodate the cutting wheel of the cutting machine and prevent it from colliding with the table surface. The cutting block limiting plate 105 is also an adjustable structure, used to guide the strip-shaped raw material plate and limit its transverse position on the longitudinal table 102 to ensure that it is aligned with the cutting groove.

The conveying directions of the third conveying component 11 and the first conveying component 2 are perpendicular to each other. The third conveying component 11 is arranged within the rectangular area formed by the second longitudinal cutting groove 109 and the transverse cutting groove 110.

[0042] To ensure that the third conveying component 11 does not interfere with the adsorption fixing component 9 when conveying finished products, the overall height of the third conveying component 11 is designed to be slightly higher than the top surface of the adsorption plate 901, and when the movable frame 202 descends, the top surface of the conveying roller 204 is flush with the top surface of the longitudinal platform 102 so as to receive finished products.

[0043] The adsorption and fixing component 9 includes a vacuum machine 903 and several adsorption plates 901. The vacuum machine 903 is disposed in the longitudinal platform 102 and is connected to the bottom of several adsorption plates 901 through a connecting pipe 902. The adsorption plates 901 are disposed in the rectangular area formed by the second longitudinal cutting groove 109 and the transverse cutting groove 110.

[0044] The adsorption plate 901 is a porous ceramic plate or a precision-machined metal plate with densely packed micropores on its surface, and its top surface is flush with the top surface of the longitudinal stage 102. Each adsorption plate 901 is equipped with an independent on / off valve at its bottom. The control box 10 can automatically open the corresponding area of ​​the adsorption plate 901 according to the size of the strip-shaped raw material plate to optimize the vacuum adsorption force and save energy.

[0045] Example 2: See Figure 1 Based on Embodiment 1, both the first measuring device 7 and the second measuring device 8 are line laser width measuring instruments. The line laser width measuring instrument is set at the corresponding position of the workbench 1 through an arched gantry. The first measuring device 7 is used to measure the width of the strip-shaped raw material plate and compare the measurement result with the cutting width of the strip cutting assembly 4. The second measuring device 8 is used to measure the width of the block-shaped glass cover plate and compare the measurement result with the cutting width of the block cutting assembly 6.

[0046] Explanation of the working principle of size compensation: The core of this device for size compensation lies in dynamically adjusting the cutting parameters to offset material deformation through data acquisition and feedback control. The specific process is as follows: First, the control system records the preset cutting width of the strip cutting component 4 when cutting the large raw material plate, denoted as L1. After the large raw material plate is cut into strips, its internal stress is gradually released and the size tends to stabilize during the process of being conveyed to the longitudinal stage 102 via the second conveying component 3. When the strip raw material plate passes the first measuring device 7, the first measuring device 7 performs a high-precision scan of its actual width and records the deformed size at this time as L2. The control system compares and calculates L1 and L2 to obtain the width difference caused by material deformation, which is the value that needs to be compensated, denoted as D1 (D1 = L1 - L2). When the strip raw material plate enters the longitudinal stage 102 for the block cutting process, the control system automatically adjusts the cutting width of the block cutting component 6 according to the preset final glass cover plate finished product target size L0, combined with the calculated compensation value D1. Specifically, the side trimming component 602 in the cutting assembly 6 adjusts the spacing between the two second longitudinal cutters 608 according to instructions, ensuring that the cutting width L3 satisfies the relationship: L3 + D1 = L0. That is, by pre-amplifying or reducing the cutting width by a value D1, potential subsequent material deformation is offset, ensuring that the finished product size reaches L0 under ideal conditions. After cutting, the formed block-shaped glass cover is conveyed to the conveyor table 103 via the third conveying assembly 11, and undergoes final dimensional verification when passing the second measuring device 8. The actual value measured by the second measuring device 8 is recorded as L4. The control system compares L4 with the target size L0 and calculates the secondary deviation value D2 (D2 = L4 - L0). This D2 value reflects minor errors remaining after the initial compensation or additional deformation caused by environmental factors. The control system uses D2 as a new adjustment basis, and in subsequent batches or subsequent strips of the same batch, further fine-tunes the cutting width L3 of the cutting assembly 6 (e.g., adjusting it to L0 + D1 - D2), forming a continuous closed-loop optimization, thereby gradually approaching zero error and ensuring that all produced glass covers are dimensionally consistent and meet precision requirements. The preset width values ​​of the second longitudinal cutting groove 109 and the transverse cutting groove 110 meet the displacement requirements of the cutting device based on compensation adjustment.

[0047] The above control logic runs in a programmable logic controller (PLC) or a dedicated industrial computer inside the control box 10. Its built-in storage module can record all measurement data and compensation history, which facilitates quality traceability and process analysis.

[0048] To achieve the aforementioned micron-level dimensional compensation accuracy requirements, all threaded rods and their corresponding driving components in this invention utilize high-precision transmission and control assemblies. Specifically, the first unidirectional threaded rod 404 and its second driving component 408 in the slitting assembly 4, the second unidirectional threaded rod 503 and its third driving component 504 in the adjusting assembly 5, the bidirectional threaded rod 604 and its fourth driving component 605 in the side-end trimming assembly 602, and the third unidirectional threaded rod 609 and its fifth driving component 610 in the transverse cutting assembly 603 are all preferably combinations of ground-grade ball screws and servo motors. The ground-grade ball screw has a lead accuracy of ±0.003mm / 300mm and possesses extremely low backlash and stable transmission stiffness; the servo motor, in conjunction with it, has a built-in high-resolution encoder (typically 23 bits or higher, i.e., up to 8,388,608 pulses per revolution), which, in conjunction with the CNC system in the control box 10, can achieve instruction unit outputs as small as 0.0001mm. The control box 10 provides precise pulse control of the servo motor, driving the corresponding threaded rod to rotate, which in turn drives each movable block (such as the first movable block 405, the second movable block 505, the fourth movable block 606, and the fifth movable block 611) to perform micron-level linear displacement. For example, when it is necessary to adjust the distance between the two second longitudinal cutters 608 in the side-end trimming assembly 602 according to the compensation value D1, the fourth drive unit 605 receives the pulse command from the control box 10 and drives the bidirectional threaded rod 604 to rotate at a precise angle, causing the two fourth movable blocks 606 to drive the third telescopic member 607 and the second longitudinal cutters 608 to move towards or away from each other, with a movement resolution of up to 0.001 mm. Similarly, when further fine-tuning is required according to the secondary deviation value D2, the above-mentioned servo drive system can also respond to the command of the control box 10 and perform sub-micron-level compensation actions. This high-precision ball screw combined with a servo motor ensures that the invention can accurately respond to minute deformations detected by the first measuring device 7 and the second measuring device 8, achieving dynamic and precise compensation for the cutting width, thereby ensuring that the dimensional accuracy of the final glass cover is stably controlled within the allowable tolerance range.

[0049] Working Principle: When the device is started, large raw material plates are conveyed by the first conveying assembly 2 on the horizontal platform 101. Specifically, the first driving member 207 drives the roller shaft 203 and the conveying roller 204 to rotate through the meshing transmission of the first gear 205 and the second gear 206. At the same time, the lifting column 201 can adjust the height of the movable frame 202 to adapt to the input of raw material plates of different thicknesses, and the feeding limit plate 104 ensures that the large raw material plates are accurately aligned. When the large raw material plate is conveyed to the bottom of the cutting assembly 4, one end of the large raw material plate is abutted by the cutting limit plate 107. The first telescopic member 402 drives the pressing plate 403 to descend to fix the raw material plate. Then, the second driving member 408 drives the first one-way threaded rod 404 to rotate, which drives the first movable block 405 and its second telescopic member 406 and the first longitudinal cutter 407 to move longitudinally. The first longitudinal cutter 407 descends and cuts the large raw material plate along the first longitudinal cutting groove 108, dividing it into strip-shaped raw material plates. After cutting, the strip-shaped raw material plate is turned to be conveyed by the second conveying component 3. The cutting limit plate 107 plays a guiding role during conveying. Multiple other limit structures can be set at intervals at the connection between the horizontal platform 101 and the vertical platform 102 to better convey the strip-shaped raw material plate between the two cutting limit plates 105.

[0050] Before entering the longitudinal stage 102, the strip-shaped raw material plate first passes through the working area of ​​the first measuring device 7, which measures its actual width in real time and sends the data to the control box 10. Then, the strip-shaped raw material plate enters the longitudinal stage 102, where it is adsorbed and fixed to the surface of the longitudinal stage 102 by the vacuum unit 903 in the adsorption and fixing assembly 9 through the connecting pipe 902 and the adsorption plate 901. Next, the adjusting assembly 5 begins to work: the third driving member 504 drives the second one-way threaded rod 503 to rotate, causing the second movable block 505 and its cutting assembly 6 to move longitudinally along the guide rail 506 and the third movable block 507 on the longitudinal stage 102 to the preset station. When the cutting assembly 6 is working, the fourth drive member 605 in the side trimming assembly 602 drives the bidirectional threaded rod 604 to rotate, causing the two fourth movable blocks 606 and their third telescopic members 607 and the second longitudinal cutter 608 to move towards or away from each other, so as to accurately adjust the cutting spacing according to the width data measured by the first measuring device 7, and perform fine trimming on both sides of the strip-shaped raw material plate, with the cutting trajectory corresponding to the second longitudinal cutting groove 109. Subsequently, the fifth drive member 610 in the transverse cutting assembly 603 drives the third unidirectional threaded rod 609 to rotate, causing the fifth movable block 611 and its fourth telescopic member 612 and the transverse cutter 613 to move laterally, cutting the strip-shaped raw material plate laterally along the transverse cutting groove 110 to form a block-shaped glass cover plate. The cutting limiting plate 105 plays a limiting and guiding role in this process.

[0051] While the transverse cutting component 603 is operating, the adsorption and fixing component 9 maintains the adsorption of the strip-shaped raw material plate to ensure that it does not shift during the cutting process. When the strip-shaped raw material plate in a certain area is completely cut, the adsorption plate 901 in that area can automatically close the vacuum so that the third conveying component 11 can transport the finished product away.

[0052] The cut block glass cover is conveyed to the conveyor table 103 by the third conveying assembly 11 located within the area enclosed by the second longitudinal cutting groove 109 and the transverse cutting groove 110, and finally output by the conveyor belt 106. During the output process, the block glass cover passes through the working area of ​​the second measuring device 8, which verifies its final dimensions and feeds the results back to the control box 10 for subsequent optimization and adjustment of process parameters, thereby achieving closed-loop compensation for material deformation and ensuring product dimensional accuracy.

[0053] The end of the conveyor 103 can be connected to subsequent cleaning, testing, or packaging equipment to form a complete automated production line. The control box 10 can also integrate a human-machine interface for displaying equipment status, inputting process parameters, and manual debugging.
