Description

Technical Field

[0001] This utility model relates to the field of glass edging technology, specifically to a double-sided edging device for flat glass. Background Technology

[0002] In the production and processing of flat glass, edge grinding is a crucial step. Its purpose is to remove burrs and sharp edges from the cut glass, improving its safety, aesthetics, and suitability for subsequent assembly. With the increasing demand for flat glass from industries such as construction, furniture, and electronics, and the gradually increasing requirements for glass processing precision and efficiency, traditional flat glass edge grinding equipment has gradually revealed many shortcomings.

[0003] Traditional flat glass edging often uses a single-edge edging method, meaning that only one edge of the glass can be edged at a time. Grinding all four edges of a single piece of glass requires multiple adjustments to the clamping position and orientation, which is not only cumbersome but also significantly reduces production efficiency, making it difficult to meet the demands of large-scale mass production. Furthermore, the repeated adjustments can easily lead to inconsistent edging precision across the glass edges due to positioning deviations, affecting product quality. Utility Model Content

It is equipped with an absolute encoder, providing a positioning accuracy of ±0.03mm, and is fixed to the mounting beam at the top of the grinding frame 3 using M16 bolts. The bottom of the transverse moving mechanism 16 is rigidly connected to the slider of the electric slide rail 15 via bolts, with locating pins on the connection surface to ensure coaxiality.

[0027] In some technical solutions, the bottom end of the grinding frame 3 is compressed with a spring 23, and the end of the compressed spring 23 is equipped with a compression plate 24.

[0028] The compression spring 23 is a cylindrical helical compression spring made of 60Si2Mn, with a diameter of 25mm, a free length of 100mm, a compression stroke of 30mm, and a stiffness of 5N / mm. Four compression springs are evenly distributed at the bottom of each grinding frame 3 in a rectangular arrangement. The compression plate 24 is made of rubber with a Shore hardness of 60 degrees and dimensions of 150mm×100mm×10mm. The back is connected to the compression spring 23 via a steel plate support plate with a thickness of 5mm. The spring end is fixed by a threaded connection. The other end of the compression spring 23 is fixed to the bottom crossbeam of the grinding frame 3 via a spring seat.

[0030] The movable block 8 is made of cast iron and measures 150mm×100mm×80mm. Its bottom is fitted with a slider that matches the T-shaped groove of the grinding table 2. The slider is made of wear-resistant cast iron with a polytetrafluoroethylene coating and a friction coefficient ≤0.1.

The width is 10mm smaller than the height of the glass clamp, and a 5mm gap is reserved at the top and bottom to avoid interference between the protective layer and the grinding table or other components.

[0033] In some technical solutions, a limit plate 4 is installed on the edge grinding frame 3.

[0034] The limiting plate 4 is made of 45# steel with heat treatment, with a thickness of 10mm and a size of 100mm×80mm. The surface is hardened to a hardness of HRC40-45. The limiting plate 4 is fixed to the column of the grinding frame 3 by M10 hex bolts. Two limiting plates are installed for each transverse moving mechanism 16, located at both ends of the moving stroke. The distance between the limiting plate and the transverse moving mechanism 16 is 10mm. A 5mm thick rubber buffer pad is pasted on the inner side of the limiting plate 4. The buffer pad is made of nitrile rubber to reduce the impact of collision. At the same time, a limit switch, model LX19-001, is installed on the limiting plate 4. When the transverse moving mechanism touches the limiting plate, the limit switch sends a signal to control the equipment to stop.

[0035] Work process:

[0036] I. Preliminary Preparation Stage

[0037] Equipment debugging and inspection: The operator first checks the overall condition of the equipment, confirms that the shock-absorbing feet of the equipment base plate 1 are adjusted to be level (tested with a level, the level error is ≤0.2mm / m), and locks the feet. Check whether the surface of the grinding table 2 is clean and free of debris and oil stains; whether the glass clamping plates a14 and b9 of the glass clamping assembly 6 are deformed or damaged, and whether the protective layer 12 is peeling off or worn; whether the connecting bolts of the grinding frame 3 are loose, whether the limit switch (model LX19-001) on the limit plate 4 is properly wired, and whether the rubber buffer pad is intact.

[0038] Power and media connection: Connect the main power supply of the equipment (380V three-phase AC), start the control system (such as PLC control cabinet), and check whether the power supply and signal connection of the power components such as electric slide rail 15, drive motor 21, electric push rod 18, and clamping cylinder 11 are normal. If the equipment is equipped with a cooling system (such as a grinding edge cooling water spray device, which is a supplementary configuration), the cooling water pipe needs to be connected and the valve opened to ensure that the cooling water supply is unobstructed.

[0039] Edge grinding roller compatibility: Based on the thickness of the flat glass to be processed (e.g., 3-12mm) and the edge grinding precision requirements (e.g., fine grinding, coarse grinding), select the glass edge grinding roller 20 with the corresponding grit (80 grit for coarse grinding, 200 grit for fine grinding). Confirm that the key connection between the roller and the drive shaft is firm, the bearing (model 6205) rotates flexibly without jamming, and the transmission sprocket 22 meshes well with the chain (model 16A-1). Adjust the chain tension through the tensioning wheel to ensure that there is no loosening or skipping of teeth.

[0040] II. Glass Clamping Stage

[0041] Glass positioning: Place the flat glass to be processed on the grinding table 2. Using the edge of the grinding table or the preset positioning baffle (supplementary positioning mechanism) as a reference, adjust the position of the glass so that the two opposite edges that need to be ground extend out of both sides of the grinding table. The extension length is adapted to the thickness of the glass grinding roller 20 (usually 30-50mm) to ensure full coverage of the double-sided grinding range.

[0042] Clamping cylinder activation: The control system issues a command to activate clamping cylinder 11 (model SC100×300). The cylinder working pressure is adjusted to 0.5-0.6MPa (adjusted according to the glass thickness; the greater the thickness, the slightly higher the pressure). The piston rod of the clamping cylinder extends, pushing the moving block 8 along the T-shaped slide groove of the grinding table 2, causing the glass clamping plate a14 to move closer to the glass clamping plate b9.

[0043] Stable clamping and protection: When the protective layer 12 (polyurethane foam, 8mm thick) between glass clamp a14 and glass clamp b9 is attached to both sides of the glass, the control system detects the clamping force through a pressure sensor (supplementary detection device). Once the preset value (e.g., 500-800N) is reached, the clamping cylinder stops operating and maintains pressure. The protective layer buffers the clamping force through elastic deformation, preventing scratches or damage to the glass surface, while ensuring no displacement of the glass during the edging process.

[0044] Assisted compression and fixing: Activate the compression structure at the bottom of the edge grinding frame 3, and manually or automatically control the compression plate 24 (rubber material, Shore hardness 60 degrees) to contact the upper surface of the glass. The compression spring 23 (material 60Si2Mn, stiffness 5N / mm) generates a pre-compression amount (such as 10-15mm), and uses the spring force to longitudinally assist in fixing the glass, further improving the stability of the glass.

[0045] III. Grinding Parameter Setting Stage

[0046] Lateral position adjustment: Based on the glass length specifications (e.g., 800-1600mm), the operating parameters of the electric slide rail 15 (model LSA20) are set through the control system. The electric slide rail drives the lateral movement mechanism 16 to move along the top of the edging frame 3, adjusting the distance between the two lifting frames 17 so that the two glass edging rollers 20 are aligned with the edges to be edged on both sides of the glass. The ball screw (30mm diameter) of the lateral movement mechanism has a transmission accuracy of ±0.02mm, ensuring accurate roller positioning.

[0047] Lifting height adjustment: Based on the glass thickness, the stroke of the electric push rod 18 (model DT30) is set. The electric push rod drives the grinding frame 19 and the glass grinding roller 20 to descend, so that the grinding surface of the roller contacts the edge of the glass. The lifting frame 17 adopts a square telescopic sleeve structure, combined with a linear bearing (model LM50UU), to ensure a smooth descent. The contact pressure between the roller and the glass is controlled at 100-200N (adjusted by the thrust of the electric push rod) to avoid excessive pressure causing glass breakage or insufficient pressure affecting the grinding effect.

[0048] Rotation speed and speed setting: Set the rotation speed of the drive motor 21 (power 2.2kW), and adjust the rotation speed of the glass edging roller 20 to 1000-1450r / min through frequency conversion speed regulation (slightly lower speed during coarse grinding and slightly higher speed during fine grinding); at the same time, set the running speed of the electric slide rail (0-300mm / s), that is, the speed at which the roller moves along the edge of the glass during the edging process, to ensure uniform and efficient edging.

[0049] IV. Edge Grinding Stage

[0050] Drive system start: The control system issues a grinding start command, the drive motor 21 runs, and drives the glass grinding roller 20 to rotate at high speed through the transmission sprocket 22 and chain. At the same time, the cooling system starts, spraying cooling water onto the grinding part to reduce the grinding temperature, remove glass debris, and prevent the grinding roller from overheating and wearing or the glass edge from cracking due to high temperature.

[0051] Double-sided synchronous edge grinding: The electric slide rail 15 drives the transverse moving mechanism 16 to move at a constant speed, which in turn drives two rotating glass grinding rollers 20 to move synchronously along the two opposite edges of the glass to perform grinding operations. During the movement, the limit switch on the limit plate 4 monitors the position of the transverse moving mechanism in real time. When it approaches the travel limit, the limit switch sends a signal to control the electric slide rail to decelerate or stop, preventing overtravel collisions.

[0052] Dynamic monitoring and adjustment: During the edge grinding process, the control system monitors the pressure of the clamping cylinder, the thrust of the electric push rod, and the load current of the drive motor in real time. If glass displacement causes abnormal load (such as the current exceeding the rated value by 15%), the system will automatically issue an alarm and reduce the speed of the electric slide rail or stop the edge grinding process. The system will restart after the operator checks and adjusts the settings.

[0053] Edge grinding complete and reset: When the lateral moving mechanism drives the roller to the end of the glass edge and completes the edge grinding of one edge, the control system controls the electric push rod to drive the edge grinding roller to rise and disengage from the glass. At the same time, the electric slide rail drives the lateral moving mechanism back to the initial position. If the glass needs to be edge ground on the other two edges, the glass orientation can be adjusted manually or automatically by the rotating mechanism (a supplementary auxiliary mechanism), and the above clamping and edge grinding steps can be repeated.

[0054] V. Shutdown and Finalization Phase

[0055] Equipment shutdown: After all edge grinding operations are completed, first turn off the drive motor, electric slide rail, electric push rod and other power components, then turn off the air source of the clamping cylinder to reset the glass clamp a14 and release the glass. Turn off the cooling system and the main power supply.

[0056] Glass Removal and Cleaning: The operator removes the ground glass from the grinding table 2 and checks the grinding quality (edge ​​smoothness, dimensional accuracy). Qualified products are transferred to the next process. Clean the glass shards and cooling water from the surface of the grinding table, and wipe the glass clamps and protective layer with a soft cloth to ensure no shards remain.

[0057] Equipment maintenance: Check the wear of the glass edging roller 20. If the abrasive wear exceeds 20%, replace the roller in time. Clean the debris on the transmission sprocket and chain, and apply lubricating oil (such as lithium-based grease). Check whether the elasticity of the compression spring 23 has decreased and whether the protective layer 12 is damaged. Replace it in time if there are any problems. Record the equipment operating parameters and fault conditions to form a maintenance log.
