Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing technology, and in particular to a multi-directional limiting tempered glass drilling device. Background Technology
[0002] In the glass processing industry, tempered glass is widely used in building curtain walls, automobile windows, electronic device screens, and other fields due to its high strength and impact resistance. However, tempered glass is hard and brittle, and its drilling process places strict requirements on positioning accuracy, stress uniformity, and processing flexibility.
[0003] Traditional tempered glass drilling equipment suffers from the following technical problems: 1. Insufficient positioning accuracy: Traditional equipment often uses a single linear limit or multi-directional limit through simple mechanical blocks. However, tempered glass comes in various sizes and has a high degree of surface flatness. A single linear limit is prone to positioning deviations due to glass placement offset or transmission errors. Especially in oblique processing scenarios, the lack of effective oblique constraints makes it difficult to meet the requirements for high-precision hole positioning. 2. Poor lifting stability: When drilling glass, it needs to be detached from the conveyor belt to avoid vibration interference. Traditional lifting mechanisms often use single-point or multi-point rigid lifting. However, tempered glass is brittle, and localized stress concentration can easily lead to breakage. Furthermore, if the glass does not fit evenly against the lifting surface during lifting, it may cause warping deformation, affecting the verticality of the drill hole. 3. Low processing flexibility: Tempered glass has diverse practical applications. Traditional drilling equipment often relies on changing drill bits or adjusting the equipment structure to achieve multi-specification and multi-coordinate processing. This is cumbersome and inefficient, making it difficult to adapt to the flexible production needs of small batches and multiple varieties. 4. Weak adaptability: For irregularly shaped or large-sized glass, traditional limiting mechanisms cannot dynamically adjust the limiting angle or distance, requiring manual intervention to reposition, which leads to a longer processing cycle and reduced production efficiency.
[0004] In summary, there is an urgent need for a tempered glass drilling device with high positioning accuracy, stable lifting, flexible processing, and strong adaptability to solve the problems of large positioning deviation, easy breakage, and low processing efficiency in the existing technology. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a multi-directional limiting tempered glass drilling device.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a multi-directional limiting tempered glass drilling device, comprising: a conveying platform for conveying the glass to be processed, including a conveyor belt and a power unit for driving the conveyor belt; and a glass positioning assembly, disposed at the feeding end of the conveying platform, which is a multi-directional limiting mechanism, including: a first limiting roller for preliminary forward positioning of the glass, a second limiting roller symmetrically distributed on both sides of the width direction of the conveying platform for limiting the glass in the left-right direction, and a third limiting roller opposite to the first limiting roller for limiting the glass in the backward or oblique direction. The system includes a clamping and pushing assembly and a rotating pushing assembly that drive the second and third limiting rollers respectively; a lifting assembly, which is hidden in the internal space below the glass positioning assembly, including multiple parallel cylindrical lifting rods, a top support ball, a lifting bracket and a vertical lifting cylinder, used to lift the positioned glass away from the conveyor belt; and a drilling assembly, a multi-axis drilling mechanism symmetrically arranged above the glass positioning assembly, including an XY drive assembly and replaceable multi-specification drill bits, used to perform multi-axis drilling in the XY plane on the lifted glass.
[0007] As a preferred embodiment of this utility model, in the glass positioning assembly: the first limiting roller consists of two parallel vertically arranged rollers, symmetrically fixed to the two sides of the feed end along the width direction of the transmission platform, used to limit the front end position of the glass; the second limiting roller is a horizontal roller, the bottom of which is connected to the clamping and pushing assembly through a second roller mounting seat, and the roller surface contacts the left and right sides of the glass, used to limit the left and right position of the glass; the third limiting roller is an inclined roller, the inclination angle of which can be adjusted by the rotating and pushing assembly, the bottom of which is connected to the rotating and pushing assembly through a third roller mounting seat, and the roller surface contacts the rear side or oblique side of the glass, cooperating with the first limiting roller to form a closed limiting area in the feed direction of the transmission platform.
[0008] As a preferred embodiment of this utility model, in the lifting assembly: the lifting rods are multiple parallel cylindrical rods, with their tops embedded in the fixing grooves at the bottom of the top support ball, dispersing the lifting force through spherical contact; the lifting bracket is a horizontal frame structure, with the bottom of each lifting rod fixedly connected to the top of the lifting bracket, used to synchronously drive all lifting rods to rise and fall; the lifting cylinder is fixed to the bottom of the transmission platform, with its piston rod fixedly connected to the center position of the bottom of the lifting bracket, used to drive the lifting bracket and lifting rods to move vertically, lifting the glass off the conveyor belt.
[0009] As a preferred embodiment of this utility model, in the drilling assembly: the XY drive assembly includes an X-axis linear module arranged along the length direction of the transmission platform and a Y-axis linear module arranged along the width direction of the transmission platform, which together form a two-dimensional drive mechanism for driving the drill bit to move along any trajectory in the XY plane; the drill bit is a replaceable drilling tool of different specifications, which is fixed to the end of the moving platform of the XY drive assembly by a drill chuck, and the axis of the drill bit is perpendicular to the top surface of the glass for drilling.
[0010] As a preferred embodiment of this utility model, the clamping and pushing assembly includes: a horizontal mounting plate fixed to the side of the transmission platform, with its length direction perpendicular to the transmission direction of the transmission platform, and its bottom fixedly connected to the transmission platform by bolts; two horizontal linear guide rails parallel to the side of the horizontal mounting plate for guiding the movement trajectory of the second roller mounting seat; a horizontal pushing drive cylinder installed at the top of the horizontal mounting plate, with its piston rod parallel to the horizontal linear guide rails for driving the second roller mounting seat to move along the guide rails; and a second roller mounting seat, with its top detachably connected to the bottom of the second limiting roller for driving the second limiting roller to move horizontally closer to or away from the glass.
[0011] As a preferred embodiment of this utility model, the rotating and pushing assembly includes: two symmetrically arranged connecting plates, respectively fixedly connected to the two sides of the third roller mounting base; two cylindrical rotating support shafts symmetrically arranged on both sides of the connecting plates, rotatably mounted on the connecting plates via bearings, for supporting the rotational movement of the connecting plates; a driving slider, which is a square slider fixedly connected to the side of the connecting plates and slidably engaged with the sliding guide rail; two linear sliding guide rails fixed to the inner side of the transmission platform, extending along the width direction of the transmission platform, for guiding the horizontal movement trajectory of the driving slider; a flipping driving cylinder, hinged to the middle of the connecting plate, whose piston rod is hinged to the bottom of the driving slider via a cylinder connecting block, for driving the connecting plate to rotate around the rotating support shafts and adjusting the tilt angle of the third limiting roller; and a horizontal driving cylinder, fixed to the middle of the transmission platform, whose piston rod is fixedly connected to the end of the sliding guide rail via a horizontal connecting block, for pushing the driving slider to move along the sliding guide rail, thereby causing the third limiting roller to move horizontally closer to or away from the glass.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device employs a three-directional limiting mechanism: "forward preliminary positioning + left-right clamping + backward / oblique dynamic constraint." The first limiting roller defines the front reference position, the second limiting roller achieves adaptive left-right clamping through a horizontal pushing component, and the third limiting roller's tilt angle can be adjusted through a rotating pushing component. These three components work together to form a closed limiting area, significantly reducing positioning deviations caused by glass placement offset or transmission errors. Testing shows that compared to traditional single linear limiting devices, the hole positioning accuracy of this device can be improved to ±0.1mm, meeting the requirements of precision machining. 2. The lifting assembly adopts a design of "multiple parallel lifting rods + top support ball + synchronous lifting bracket": multiple lifting rods are evenly distributed, and the lifting force is dispersed by the spherical contact of the top support ball. The synchronous lifting bracket ensures that all lifting rods rise and fall in a consistent manner, preventing the glass from warping due to uneven force. In addition, the lifting assembly is hidden under the positioning assembly to avoid external interference and further improve lifting stability. 3. The drilling assembly adopts XY dual-axis linear module drive, which can realize arbitrary trajectory movement in the XY plane. With the interchangeable multi-specification drill bits, it supports multiple types of processing such as micro holes, deep holes, and inclined holes. It eliminates the need for frequent equipment changes or structural adjustments, significantly improving processing flexibility. 4. The second limiting roller (left and right direction) achieves rapid clamping / releasing in the horizontal direction through the clamping and pushing assembly. The third limiting roller (backward / oblique direction) achieves dynamic adjustment of the tilt angle and horizontal distance through the rotating pushing assembly. It can adapt to tempered glass of different sizes and shapes, without the need for manual repositioning, greatly shortening the changeover time (from the traditional 15 minutes / time to 3 minutes / time), and effectively improving the continuous operation capability of the production line.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0015] In the attached diagram, all identical reference numerals refer to the same components.
[0016] Example 1: Basic Multi-directional Tempered Glass Drilling Device like Figures 1-5 As shown, this embodiment is applicable to drilling tempered glass of conventional sizes (800mm-1500mm in length and 500mm-1000mm in width), and focuses on demonstrating the basic connection relationship and core function of each component.
[0017] Transmission Platform 1: The conveyor belt is made of plastic (with a polished surface) and is driven by a servo motor (power unit) installed at the bottom. The transmission speed is adjustable (0.1m / s-0.5m / s) and is used to uniformly transport the glass to be processed to the positioning area.
[0018] Please see Figure 2 , Figure 4Glass positioning component 2: Located at the feeding end of the transmission platform 1 (approximately 100mm from the front end), comprising: a first limiting roller 21: two parallel vertically arranged rollers (80mm in diameter), symmetrically fixed to the two sides of the feeding end of the transmission platform 1 along the width direction (the spacing is adapted to the width of the glass), the roller surface is in contact with the upper surface of the front end of the glass, and the front end position of the glass is limited by physical blocking; a second limiting roller 22: a horizontal roller (60mm in diameter), the bottom of which is connected to the clamping and pushing component 23 through the second roller mounting seat 221. The second roller mounting base 221 is an L-shaped metal plate with a mounting groove on the top that matches the bottom bearing of the second limiting roller 22. Its side surface slides into contact with the horizontal linear guide rail 232 of the clamping and pushing assembly 23. The clamping and pushing assembly 23 includes a horizontal mounting plate 231 (fixed to the side of the transmission platform 1, with its length perpendicular to the transmission direction), two parallel horizontal linear guide rails 232 (the spacing of which matches the second roller mounting base 221), a horizontal pushing drive cylinder 233 (mounted at the top of the horizontal mounting plate 231, with its piston rod parallel to the horizontal linear guide rail 232), and the second roller mounting base 221. The cylinder 233 pushes the second roller mounting base 221 along the guide rails, causing the second limiting roller 22 to move horizontally closer to or further away from the glass, achieving left-right clamping and limiting. The third limiting roller 24 is an inclined roller (70mm in diameter), with its bottom connected to the rotating pushing assembly 25 via the third roller mounting base 241. The third roller mounting base 241 is a flat plate support with an arc-shaped groove at the top that matches the bottom bearing of the third limiting roller 24; the rotating and pushing assembly 25 includes two symmetrically arranged connecting plates 251 (fixed to both sides of the third roller mounting base 241 respectively), two cylindrical rotating support shafts 252 (rotatably mounted on the connecting plates 251 via bearings), a driving slider 253 (a square metal block fixedly connected to the side of the connecting plate 251), two linear sliding guide rails 254 (fixed to the inside of the transmission platform 1 and extending along the width direction), a flipping driving cylinder 255 (hinged to the middle of the connecting plate 251, with the piston rod hinged to the bottom of the driving slider 253 via a cylinder connecting block 256), and a horizontal driving cylinder 257 (fixed to the middle of the transmission platform 1, with the piston rod fixedly connected to the end of the sliding guide rail 254 via a horizontal connecting block 258). The flip cylinder 255 drives the connecting plate 251 to rotate around the rotating support shaft 252, adjusting the tilt angle of the third limiting roller 24 (adjustable from 0° to 90°); the horizontal cylinder 257 pushes the driving slider 253 to move along the sliding guide rail 254, causing the third limiting roller 24 to move horizontally closer to or away from the glass, cooperating with the first limiting roller 21 to form a closed limiting area.
[0019] Please see Figure 5The lifting assembly 3 is concealed below the glass positioning assembly 2 (in the hollow area inside the transmission platform 1) and includes multiple parallel cylindrical lifting rods 31 (50mm in diameter, spaced 100mm apart), a top support ball 32 (100mm in diameter, with a hemispherical fixing groove at the bottom matching the top of the lifting rods 31), a lifting bracket 33 (a horizontal frame structure welded from square steel, with the bottom of each lifting rod 31 bolted to the top of the bracket), and a vertical lifting cylinder 34 (fixed at the center of the bottom of the transmission platform 1, with its piston rod bolted to the center of the bottom of the lifting bracket 33). The lifting cylinder 34 drives the bracket 33 and the lifting rods 31 to rise synchronously, and the support ball 32 contacts the bottom surface of the glass and disperses the lifting force, smoothly lifting the glass away from the transmission belt.
[0020] Drilling assembly 4: Symmetrically positioned above glass positioning assembly 2 (200mm above transmission platform 1), including XY drive assembly 41 and replaceable multi-specification drill bits 42. XY drive assembly 41 consists of X-axis linear module 411 (set along the length of transmission platform 1, with a stroke of 1000mm) and Y-axis linear module 412 (set along the width of transmission platform 1, with a stroke of 800mm), which are fixed by module connecting plate, driving drill bit 42 to move along any trajectory in the XY plane; drill bit 42 is fixed to the end of the moving platform of XY drive assembly by drill chuck 421, and the drill bit axis is perpendicular to the top surface of glass (the perpendicularity can be finely adjusted by adjusting the module installation angle), used for drilling.
[0021] The method of using this utility model is as follows: 1. The glass is conveyed to the feeding end by the transmission platform 1 → the first limiting roller 21 limits the position of the front end; 2. The clamping and pushing assembly 23 drives the second limiting roller 22 to horizontally clamp the left and right sides of the glass → the rotating pushing assembly 25 adjusts the tilt angle of the third limiting roller 24 and horizontally presses against the rear side of the glass; 3. Lifting cylinder 34 drives lifting assembly 3 to lift the glass away from the conveyor belt → XY drive assembly 41 drives drill bit 42 to drill a hole along the preset path → After drilling is completed, lifting assembly 3 descends and the glass falls back onto the conveyor belt, completing the unloading.
[0022] Example 2: Drilling device for large-size oblique holes in tempered glass This embodiment addresses the processing requirements of large-size (2000mm-3000mm long, 1500mm-2000mm wide) and angled holes (30°-60° angle), focusing on demonstrating the angle adjustment function of the third limit roller 24 and the stability optimization of the lifting assembly.
[0023] Improvements to glass positioning assembly 2: The tilt angle adjustment range of the third limiting roller 24 is extended to 0°-120° (by lengthening the rotation support shaft 252 and increasing the rotation stroke of the connecting plate 251); the stroke of the horizontal drive cylinder 257 of the rotating push assembly 25 is extended to 500mm (to meet the rearward limiting requirements of large-size glass); an elastic buffer pad (made of polyurethane) is added to the bottom of the second limiting roller 22 to prevent scratches on the side of the glass during clamping.
[0024] Improvements to Lifting Component 3: The number of lifting rods 31 has been increased to 8 (80mm spacing), expanding the support range; the surface of the support ball 32 has been enhanced with anti-slip texture (to increase friction with the bottom of the glass); the lifting bracket 33 adopts a hollow frame structure (to reduce weight while maintaining strength), ensuring the accuracy of synchronous lifting of multiple lifting rods 31 (error ≤ 0.2mm).
[0025] Improvements to drilling assembly 4: The stroke of the X-axis linear module 411 of the XY drive assembly 41 is extended to 1500mm, and the stroke of the Y-axis linear module 412 is extended to 1200mm (to accommodate the processing range of large-size glass); the drill bit 42 is equipped with a special drill bit for inclined holes (taper 1:10, cutting edge angle 135°), which can be quickly switched through the drill chuck 421 (changeover time ≤30 seconds).
[0026] Workflow: For the need of oblique hole processing → the rotating push assembly 25's flipping cylinder 255 drives the connecting plate 251 to rotate around the rotating support shaft 252 to a set angle (e.g., 45°) → the third limit roller 24 tilts at 45° to contact the oblique surface of the glass on the back side → the clamping push assembly 23 drives the second limit roller 22 to horizontally clamp the left and right sides of the glass → the lifting assembly 3 lifts the glass away from the conveyor belt → the XY drive assembly 41 drives the oblique hole drill bit to move along a 45° trajectory to drill a hole → after completion, it is reset to achieve high-precision processing of large-size oblique holes.
[0027] Example 3: Multi-specification quick-change tempered glass drilling device This embodiment is designed for small-batch, multi-variety (hole diameter φ2mm-φ12mm) processing needs, and focuses on demonstrating the quick changeover function of the drilling assembly and the adaptive adjustment of the positioning assembly.
[0028] Improvements to drilling assembly 4: The X-axis linear module 411 and Y-axis linear module 412 of the XY drive assembly 41 are both driven by servo motors and ball screws (positioning accuracy ±0.05mm); the drill chuck 421 adopts a quick clamping structure (press-type locking, drill bit replacement time ≤10 seconds); a drill bit magazine (located on the side of the transmission platform 1) is configured, and the required drill bit is automatically picked up and loaded into the drill chuck 421 by a robotic arm (not shown).
[0029] Improvements to the glass positioning assembly 2: An adjustable baffle (height adjusted by bolts) is added to the bottom of the first limiting roller 21 to accommodate glass of different thicknesses (3mm-12mm); a pressure sensor is added to the horizontal pushing drive cylinder 233 of the clamping and pushing assembly 23 (to monitor the clamping force in real time and prevent the glass from breaking due to excessive clamping force); an angle encoder is added to the flipping cylinder 255 of the rotating pushing assembly 25 (to precisely control the tilt angle of the third limiting roller 24 with an error ≤0.5°).
[0030] Workflow: Receive processing instructions (including hole diameter, position, and angle parameters) → The robotic arm picks up the corresponding specification drill bit from the drill bit magazine and loads it into the drill chuck 421 → The rotating push assembly 25 adjusts the third limit roller 24 to the set angle → The clamping push assembly 23 adjusts the clamping force of the second limit roller 22 according to the glass thickness → The lifting assembly 3 lifts the glass → The XY drive assembly 41 drives the drill bit to drill according to the instructions → After completion, reset and enter the next round of processing.

Through modular design and functional integration, it achieves high-precision positioning, stable lifting, and flexible processing of multiple specifications for tempered glass drilling. It covers conventional sizes, large-size oblique holes, and small-batch, multi-variety processing scenarios, verifying the technical feasibility and practicality of this utility model device.
