Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment, specifically a small-sized glass cutting and alignment device. Background Technology

[0002] In the consumer electronics and automotive industries, the application of small-sized precision glass, such as automotive display covers, optical lens substrates, and home appliance touch panels, is becoming increasingly widespread. The processing quality of these glass products directly affects the performance and user experience of the final products.

[0003] Currently, large CNC cutting machine tools are widely used in the industry for processing large-size glass. These machines rely on technologies such as automated positioning, CNC systems, and alignment sensors to achieve efficient and precise cutting operations. However, for small-size glass, existing technology still relies mainly on semi-automated manual operation. Operators manually place the glass to be cut on a small cutting platform, align the glass horizontally by visual observation or with the aid of a simple ruler, and then manually adjust the cutting parameters and start cutting.

[0004] This operating mode has significant limitations: First, the alignment accuracy is insufficient. Due to the lack of a dedicated alignment reference system and automatic calibration function, manual adjustment is difficult to ensure the absolute horizontal alignment of the glass and the cutting path, which can easily lead to problems such as chipping of the cutting edge and dimensional deviation, affecting the yield rate. Secondly, the operation is unsafe. Small-sized glass is brittle and has sharp edges, and there is a risk of scratches, breakage, and flying debris during frequent manual handling and adjustment. Third, production efficiency is low. Manual adjustment requires repeated measurement and correction, resulting in long processing times for single pieces. Furthermore, operators who maintain a fixed posture for extended periods undergoing fine-tuning are prone to fatigue, further reducing work efficiency. Fourth, standardization is poor. Differences in adjustment habits among different operators make it difficult to control cutting consistency, hindering quality control in mass production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a small-sized glass cutting and alignment device, including a placement plate 1, a support foot 2, and a laser emitter 3. The support foot 2 is located below the placement plate 1. A top plate 4 is located at the center of the placement plate 1. The laser emitter 3 includes two sets, which are respectively located at the two perpendicularly intersecting ends of the placement plate 1. The glass plate 100 is placed on the placement plate 1. Blocks 5 are provided on the two sides where the laser emitter 3 is located. Limiting blocks 6 are provided on both sides of the block 5.

[0023] In this embodiment, a metal cloth is laid on the upper surface of the placement plate 1, and the metal cloth has openings for the lifting and lowering of the top plate 4; The placement plate 1 is made of metal and has a lifting opening for the top plate 4 in the center. The upper surface is covered with metal cloth with a thickness of 0.5-1mm, and the opening matches the top plate.

[0024] The metal cloth is used to provide stable support for the glass plate 100, and increases surface friction to prevent the glass from sliding. The opening allows the top plate 4 to be raised and lowered without affecting the reference line projection of the laser emitter 3.

[0025] In this embodiment, the support foot 2 includes a suction cup 21 and a suction cup frame 22. The suction cup 21 is disposed on the suction cup frame 22, and the suction cup frame 22 is fixedly installed below the placement plate 1. The suction cup 21 is fixed to the bottom of the placement plate 1 by the suction cup bracket 22.

[0026] Vacuum adsorption fixation plate 1 is placed on the operating table of the cutting machine to prevent the equipment from shifting due to vibration during cutting.

[0027] In this embodiment, the laser emitter 3 is mounted on the side bracket 32 ​​via an adjustable mounting plate 31, and the side bracket 32 ​​is fixedly mounted below the placement plate 1; The adjustable mounting plate 31 is provided with a vertically arranged waist-shaped hole; Two sets of laser emitters with wavelengths of 650nm and linewidths of 0.1-0.3mm are respectively installed at the two perpendicularly intersecting ends of the placement plate 1; The laser emitter is fixed to the side bracket 32 ​​by an adjustable mounting plate 31. The adjustable mounting plate has a vertical waist-shaped hole with a length of 50-80mm and a width that matches the mounting bolts.

[0028] The laser emitter projects a laser line as a horizontal and vertical alignment reference for the glass plate 100, replacing the human eye or a ruler. The height of the laser emitter can be finely adjusted up and down through the oblong holes on the adjustable mounting plate to accommodate glass plates of different thicknesses.

[0029] In this embodiment, a cylinder 41 is provided below the top plate 4, the top plate 4 is mounted on the output shaft of the cylinder 41, and the cylinder 41 is mounted below the placement plate 1 via a cylinder bracket 42.

[0030] The upper surface of the top plate 4 is 1-2 mm lower than the upper surface of the placement plate 1; The upper surface of the top plate 4 is 1-2mm lower than the placement plate 1, and the cylinder 41 is connected to the bottom through the cylinder bracket 42.

[0031] Before and after cutting, cylinder 41 drives the top plate 4 to lift slightly, gently lifting the glass plate 100 to facilitate the operator to pick up and put down the glass plate 100 and to turn the glass plate 100. After cutting both sides, the remaining two sides are cut by rotating.

[0032] In this embodiment, the limiting block 6 is provided with a slot 61, which is used to position the glass plate 100; The stop block 5 is located on the side where the laser emitter is located, and its height matches the thickness of the glass plate 100.

[0033] The glass plate 100 is blocked from sliding, limiting its X / Y axis movement range.

[0034] Limiting blocks 6 are located on both sides of the stop block 5 and have slots 61, which are rectangular slots with a width matching the thickness of the glass plate 100 and a depth of 2-3mm.

[0035] When the glass plate 100 is placed, its side is embedded in the slot 61 of the limiting block 6 to leave a cutting allowance for the uneven side. The slot restricts the angular rotation of the glass plate 100 to prevent edge chipping due to tilting during cutting.

[0036] Working principle: The device is fixed to the operating table by suction cup 21 of the support foot 2; The operator places the glass plate 100 on the placement plate 1, with the side of the plate embedded in the slot 61 of the limiting block 6 and the front end contacting the stop block 5. The laser emitter 3 projects a laser line, and the operator observes the alignment of the edge of the glass plate 100 with the laser line. The cutting equipment starts cutting along the laser reference line.

[0037] After the cutting is completed, the cylinder 41 drives the top plate 4 to rise slightly, gently lifting the glass plate 100, making it easier for the operator to turn the glass plate 100. After cutting both sides, the remaining two sides are cut by rotating. After all the cutting is completed, it is lifted up again, and the operator removes the glass plate 100 from the gap between the top plate 4 and the placement plate 1. Then, after cleaning up the waste, the next piece of glass is cut.

[0038] Based on the above, this device provides horizontal and vertical reference lines through two sets of vertical laser emitters, replacing manual visual inspection and improving alignment accuracy; The slots and stops of the limiting blocks restrict the translation and rotation of the glass plate, ensuring consistency of the initial position; The top plate is driven by a cylinder, which reduces direct contact with the glass edge when manually handling it, while also slightly lifting the glass to achieve rotation.

[0039] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
