Description

Technical Field

[0001] This utility model relates to the field of laser processing technology for glass substrates, specifically to a laser drilling device for glass substrates. Background Technology

[0002] In the fields of modern electronics manufacturing and optical materials processing, laser drilling technology for glass substrates is becoming increasingly important. With the miniaturization and high performance of electronic devices and optical components, the requirements for the processing precision and quality of glass substrates are becoming increasingly stringent. Laser drilling technology, due to its high precision, high efficiency, and non-contact processing characteristics, has become an ideal choice for glass substrate processing.

[0003] In the field of glass substrate processing, especially in high-precision drilling processes, traditional clamping and drilling methods have many shortcomings. First, traditional mechanical clamps often act directly on the glass surface, easily causing scratches or damage, especially for ultra-thin or brittle materials, which significantly impacts yield and product quality. Second, existing drilling equipment typically lacks flexibility, making it difficult to adapt to glass substrates of different sizes and shapes, resulting in low production efficiency and complex operation. Furthermore, many existing laser drilling devices can only perform drilling operations at a single position or angle, failing to meet the needs of simultaneous drilling at multiple points and angles, thus limiting their application in large-scale production.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment provides a glass substrate laser drilling processing device, including: a support frame 1, with a top platform 11 disposed on the top of the support frame 1; a clamping assembly 2 disposed inside the support frame 1; and a drilling module 3 disposed inside the top platform 11.

[0033] In this embodiment, the clamping component 2 and the drilling module 3 constitute a glass substrate laser drilling processing device according to this application.

[0034] It should also be understood that the drive motor 21, stepper motor 311, cylinder 321 and laser head 326 are all common knowledge in the field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] It should be noted that the clamping assembly 2 drives the double-threaded screw 23 to rotate via the drive motor 21, which in turn drives the clamping block 24 to clamp the glass substrate. The drilling module 3 achieves precise positioning and drilling of the laser head 326 through the rotating assembly 31 and the adjusting assembly 32, thereby achieving stable clamping and precise drilling of the glass substrate and improving processing efficiency and quality.

[0036] In addition, in this embodiment, the user first places the glass substrate on the two sets of clamping blocks 24, starts the drive motor 21, and the output end of the drive motor 21 drives the double threaded screw 23 to rotate. The double threaded screw 23 rotates and the two sets of clamping blocks 24 are centered and clamped through the threaded connection. At the same time, the bottom slider 26 of the clamping block 24 slides in the sliding groove 25 on the clamping platform 22 until the flexible clamping member on the clamping block 24 touches the outer edge of the glass substrate.

[0037] Specifically, the clamping assembly 2 includes: a drive motor 21, disposed on one side of the support frame 1; a clamping platform 22, disposed inside the support frame 1; a double-threaded screw 23, rotatably disposed inside the clamping platform 22, with one end bolted to the output end of the drive motor 21; two sets of clamping blocks 24, with their bottoms threadedly engaged with the double-threaded screw 23 and sliding on the top of the clamping platform 22; four sets of sliding grooves 25, formed on the top of the clamping platform 22; and sliders 26, disposed on both sides of the bottom of the clamping blocks 24 and slidingly embedded inside the sliding grooves 25.

[0038] In this embodiment, the flexible clamping element inside the clamping block 24 is made of silicone, which has the characteristics of preventing damage to the surface of the glass substrate and providing stable clamping. The drive motor 21 drives the double threaded screw 23 to rotate, and the clamping block 24 slides along the sliding groove 25 through threaded engagement to achieve clamping of the glass substrate. The stable clamping of the glass substrate is achieved through mechanical linkage to prevent displacement during processing.

[0039] Example 2:

[0040] Based on Example 1, when drilling is required, the user starts the stepper motor 311. The output end of the stepper motor 311 drives the worm gear 312 to rotate. The worm gear 312 meshes with the worm wheel 313 to rotate. The worm wheel 313 drives the first rotating disk 314 to rotate. The outer circumferential rotating block 316 of the first rotating disk 314 rotates in the rotating groove 315. The bottom rotating support block 317 rotates to adjust the laser head 326 to a suitable angle. Then, the cylinder 321 is started. The telescopic end of the cylinder 321 pushes the connecting rod 323. The bottom of the connecting rod 323 drives the sliding block 325 to slide on the slide rail 324 until it slides to a suitable position. Then, the laser head 326 can be started to emit laser light to drill a hole in the glass substrate.

[0041] Specifically, the punching module 3 includes: a rotating component 31, which is disposed on one side of the top platform 11; and an adjusting component 32, which is disposed inside the top platform 11.

[0042] In a preferred embodiment, the rotating assembly 31 drives the worm gear 312 to rotate via the stepper motor 311, which in turn drives the worm wheel 313 and the first rotating disk 314 to rotate, thereby achieving the rotational positioning of the laser head 326. The adjusting assembly 32 drives the connecting rod 323 and the sliding block 325 to slide via the cylinder 321, adjusting the drilling position of the laser head 326 to achieve precise positioning and drilling of the laser head 326, thus improving processing accuracy.

[0043] Specifically, the rotating assembly 31 includes: a stepper motor 311, disposed on the outer wall of one side of the top platform 11; a worm gear 312, rotatably disposed inside the top platform 11, with one end bolted to the output end of the stepper motor 311; a worm wheel 313, rotatably disposed inside the top platform 11, and meshing with the worm gear 312; a first rotating disk 314, rotatably disposed at the bottom of the top platform 11, with its top welded to the bottom of the worm wheel 313; a rotating groove 315, formed at the bottom of the top platform 11; a rotating block 316, disposed on the outer periphery of the first rotating disk 314, and embedded in the rotating groove 315 for rotation; and a rotating support block 317, disposed at the bottom of the first rotating disk 314, and rotatably disposed at the bottom of the top platform 11.

[0044] In this embodiment, the stepper motor 311 drives the worm gear 312 to rotate, which in turn drives the worm wheel 313 and the first rotating disk 314 to rotate. The rotating block 316 rotates in the rotating groove 315, and the rotating support block 317 rotates along with it to achieve the rotational positioning of the laser head 326. The precise positioning of the laser head 326 is achieved through mechanical linkage, thereby improving the drilling accuracy.

[0045] Specifically, the distance adjustment assembly 32 includes: a cylinder 321, which is disposed on the top of the top platform 11 and whose telescopic end passes through the middle of the worm gear 313; a second rotating disk 322, which is rotatably disposed on the top of the top platform 11 and whose top end is bolted to the cylinder 321, and whose telescopic end passes through the middle of the second rotating disk 322; two sets of connecting rods 323, whose tops are hinged to the telescopic ends of the cylinder 321 and rotate inside the rotating support block 317; a slide rail 324, which is disposed at the bottom of the rotating support block 317; two sets of sliding blocks 325, whose tops are hinged to the end of the connecting rod 323 away from the first rotating disk 314 and slide on the slide rail 324; and two sets of laser heads 326, which are disposed at the bottom of the sliding blocks 325 and are used for laser drilling.

[0046] With this configuration, the cylinder 321 drives the connecting rod 323 and the sliding block 325 to slide along the slide rail 324, adjusting the drilling position of the laser head 326, thereby achieving precise positioning and drilling of the laser head 326 and improving processing accuracy.

[0047] In actual use, the user first places the glass substrate on the two sets of clamping blocks 24, starts the drive motor 21, and the output end of the drive motor 21 drives the double threaded screw 23 to rotate. The double threaded screw 23 rotates and the two sets of clamping blocks 24 are centered and clamped through the threaded connection. At the same time, the bottom slider 26 of the clamping block 24 slides in the sliding groove 25 on the clamping platform 22 until the flexible clamping part on the clamping block 24 touches the outside of the glass substrate. When drilling is required, the user starts the stepper motor 311. The output end of the stepper motor 311 drives the worm gear 312 to rotate. The worm gear 312 meshes with the worm wheel 313 to rotate. The worm wheel 313 drives the first rotating disk 314 to rotate. The outer circumferential rotating block 316 of the first rotating disk 314 rotates in the rotating groove 315. The bottom rotating support block 317 rotates to adjust the laser head 326 to a suitable angle. Then, the cylinder 321 is started. The telescopic end of the cylinder 321 pushes the connecting rod 323. The bottom of the connecting rod 323 drives the sliding block 325 to slide on the slide rail 324 until it slides to a suitable position. Then, the laser head 326 can be started to emit laser light to drill holes in the glass substrate.
