Description

Technical Field

[0001] This utility model relates to the field of glass cover plate processing, and in particular to a laser positioning auxiliary device for processing irregular holes in glass cover plates. Background Technology

[0002] During the manufacturing process of glass covers (such as mobile phone screens and flat glass), irregularly shaped holes (such as camera holes, earpiece holes, and sensor holes) often need to be drilled. The precision of this drilling directly affects the product's appearance and functionality. Positioning aids are required to ensure the accuracy and consistency of the hole positions. Traditional positioning aids have the following drawbacks:

[0003] Poor clamping stability: Traditional clamping mechanisms are mostly unidirectional clamping or single-point fixing. During processing, the glass cover is prone to slight displacement due to vibration or stress concentration. Especially during high-speed laser cutting, it can easily lead to edge cracking or rough processing surface.

[0004] Based on this, we propose a laser positioning auxiliary device for processing irregular holes in glass cover plates. Utility Model Content

[0005] To address the technical problem of insufficient stability in single-point clamping, this utility model provides a laser positioning auxiliary device for processing irregular holes in glass cover plates.

[0006] This utility model is achieved by the following technical solution: a laser positioning auxiliary device for processing irregular holes in glass cover plates, including a main support, a top beam, diagonal braces, a laser head, and a support platform; the top of the main support is horizontally connected to the top beam, and the two ends of the diagonal braces are respectively fixedly connected to the top beam to form a triangular rigid frame, and the support platform is fixed in the middle of the main support.

[0007] The laser head is fixed below the diagonal brace, with its emitting end vertically downward aligned with the center of the clamping assembly, for emitting positioning laser and processing laser.

[0008] It includes a clamping assembly, which is disposed above the stage and includes a stage support, a rotating base, an electric push rod, a longitudinal guide rail, a sliding block, a sliding frame, a first connecting rod, a first shaft, a second shaft, a transmission connecting plate, a central rotating shaft, a sliding groove, and a clamping block;

[0009] The support column of the support platform is fixedly installed on the surface of the support platform. A rotating base is fixedly connected above the support column. An electric push rod is installed on the bottom surface of the rotating base. A longitudinal guide rail is connected to the top of the electric push rod. The sliding block is slidably connected to the longitudinal guide rail. The sliding frame is fixed above the sliding block. A sliding groove extending laterally is opened on the outer side of the sliding frame.

[0010] The central shaft is rotatably mounted at the center of the transmission connecting plate. A second shaft is mounted at the edge of the transmission connecting plate. The second shaft is connected to the first shaft via a first connecting rod. The first shaft is mounted on the sliding frame. The clamping block is set inside the sliding frame and slides in cooperation with the sliding groove to clamp the glass cover.

[0011] The electric push rod of the clamping assembly is activated, driving the sliding frame to move longitudinally along the longitudinal guide rail. The electric push rod further pushes the sliding frame. The rotating chassis is linked to the transmission disc through the central rotating shaft. With the hinge structure of the first connecting rod, the first shaft, and the second shaft, the sliding frame moves synchronously, driving the first shaft and the second shaft connected to it to move synchronously. This achieves synchronous movement of the four sets of sliding frames, thereby driving the clamping block to move laterally along the sliding groove, achieving clamping and fixing of the glass cover plate and preventing workpiece displacement during processing.

[0012] As a further optimization of this utility model, the clamping assembly includes four sets of symmetrically distributed sliding frames and clamping blocks. Each set of sliding frames is hinged to the edge of the transmission connecting plate through a first connecting rod. The transmission connecting plate is fixed coaxially with the rotating chassis through a central rotating shaft.

[0013] As a further optimization of this utility model, the lateral sliding direction of the sliding groove is consistent with the radial direction of the rotating chassis, and an elastic anti-slip pad is provided on the inner side of the clamping block for clamping the edge of the glass cover plate.

[0014] As a further optimization of this utility model, the glass cover plate to be processed is placed on the clamping assembly, and the support platform is connected to the main support through the support platform pillar to form a stable basic support plane.

[0015] As a further optimization of this utility model, the transmission disc has four hinge points evenly distributed on its edge, which are connected to four sets of sliding frames through the first connecting rod to form a synchronous transmission mechanism.

[0016] As a further optimization of this utility model, the working head emits a positioning laser and projects it onto the surface of the glass cover plate. By observing the overlap between the laser spot and the designed hole position, the positioning accuracy is continuously adjusted until the requirements are met.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses four sets of symmetrically distributed sliding frames and clamping blocks to achieve synchronous radial movement through a transmission connecting disc and a first connecting rod, ensuring uniform force on the edge of the glass cover plate, effectively avoiding stress concentration and workpiece deformation caused by single-point clamping, and is suitable for stable glass processing.

[0019] 2. This utility model uses an elastic anti-slip pad on the inner side of the clamping block to increase the coefficient of friction while buffering the clamping force, thus preventing the glass cover edge from cracking due to rigid contact. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1:

[0027] Please combine Figures 1-4 This embodiment proposes a laser positioning auxiliary device for processing irregular holes in glass cover plates, including a main support 1, a top beam 2, a diagonal brace 3, a laser head 4, and a support platform 5; the top of the main support 1 is horizontally connected to the top beam 2, and the two ends of the diagonal brace 3 are respectively fixedly connected to the top beam 2 to form a triangular rigid frame, and the support platform 5 is fixed in the middle of the main support 1.

[0028] Furthermore, the laser head 4 is fixed below the diagonal brace 3, with its emitting end vertically downward aligned with the center of the clamping assembly 6, for emitting positioning laser and processing laser.

[0029] Furthermore, the working head 4 emits a positioning laser, which is projected onto the surface of the glass cover plate. By observing the overlap between the laser spot and the designed hole position, adjustments are made continuously until the positioning accuracy meets the requirements.

[0030] It includes a clamping assembly 6, which is disposed above the support platform 5 and includes a support platform support 61, a rotating base 62, an electric push rod 63, a longitudinal guide rail 64, a sliding block 65, a sliding frame 66, a first connecting rod 67, a first shaft 68, a second shaft 69, a transmission connecting plate 610, a central rotating shaft 611, a sliding groove 661, and a clamping block 662.

[0031] The support column 61 of the support platform is fixedly installed on the surface of the support platform 5. A rotating base 62 is fixedly connected above the support column 61. An electric push rod 63 is installed on the bottom surface of the rotating base 62. A longitudinal guide rail 64 is connected to the top of the electric push rod 63. A sliding block 65 is slidably connected to the longitudinal guide rail 64. A sliding frame 66 is fixed above the sliding block 65. A sliding groove 661 extending laterally is opened on the outer side of the sliding frame 66.

[0032] Furthermore, the transmission disc 610 has four hinge points evenly distributed on its edge, which are connected to four sets of sliding frames 66 through the first connecting rod 67 to form a synchronous transmission mechanism.

[0033] The central rotating shaft 611 is rotatably mounted at the center of the transmission connecting plate 610. A second shaft 69 is mounted at the edge of the transmission connecting plate 610. The second shaft 69 is connected to the first shaft 68 through the first connecting rod 67. The first shaft 68 is mounted on the sliding frame 66.

[0034] The clamping block 662 is disposed inside the sliding frame 66 and slides in conjunction with the sliding groove 661 to clamp the glass cover plate.

[0035] In the specific technical solution, the glass cover plate to be processed is placed on the clamping assembly 6, and the support platform 5 is connected to the main support 1 through the support platform support column 61 to form a stable basic support plane.

[0036] More specifically, the electric push rod 63 of the clamping assembly 6 is activated, driving the sliding frame 66 to move longitudinally along the longitudinal guide rail 64. The electric push rod 63 further pushes the sliding frame 66. The rotating chassis 62 is linked with the transmission connecting plate 610 through the central rotating shaft 611. With the hinge structure of the first connecting rod 67, the first shaft 68, and the second shaft 69, the sliding frame 66 moves simultaneously, driving the first shaft 68 and the second shaft 69 connected to it to move synchronously, realizing the synchronous movement of the four sets of sliding frames 66. This drives the clamping block 662 to move laterally along the sliding groove 661, realizing the clamping and fixing of the glass cover plate and preventing the workpiece from shifting during processing.

[0037] Furthermore, the lateral sliding direction of the sliding groove 661 is consistent with the radial direction of the rotating base 62, and the inner side of the clamping block 662 is provided with an elastic anti-slip pad for clamping the edge of the glass cover plate.

[0038] It should be noted that the clamping assembly 6 includes four symmetrically distributed sliding frames 66 and clamping blocks 662. Each set of sliding frames 66 is hinged to the edge of the transmission connecting plate 610 through the first connecting rod 67. The transmission connecting plate 610 is coaxially fixed to the rotating base 62 through the central rotating shaft 611.

[0039] This laser positioning auxiliary device is used for precise positioning and clamping during the processing of irregularly shaped holes in glass cover plates. Its working principle is as follows:

[0040] Workpiece installation and preliminary positioning

[0041] Positioning of the support platform: The glass cover plate to be processed is placed on the clamping assembly 6. The support platform 5 is connected to the main support 1 through the support platform support column 61 to form a stable basic support plane.

[0042] The electric push rod 63 of the clamping assembly 6 is activated, driving the sliding frame 66 to move longitudinally along the longitudinal guide rail 64. The electric push rod 63 further pushes the sliding frame 66. The rotating chassis 62 is linked with the transmission connecting plate 610 through the central rotating shaft 611. With the hinge structure of the first connecting rod 67, the first shaft 68 and the second shaft 69, the sliding frame 66 moves simultaneously, driving the first shaft 68 and the second shaft 69 connected to it to move synchronously, realizing the synchronous movement of the four sets of sliding frames 66. This drives the clamping block 662 to move laterally along the sliding groove 661, realizing the clamping and fixing of the glass cover plate and preventing the workpiece from shifting during processing.

[0043] Positioning assistance: The working head 4 emits a positioning laser and projects it onto the surface of the glass cover. By observing the overlap between the laser spot and the designed hole position, adjustments are made continuously until the positioning accuracy meets the requirements.
