Description

Technical Field

[0001] This utility model belongs to the technical field of optical glass cold processing equipment, and relates to a general optical glass processing suction and release device, which is suitable for glass processing equipment with pins such as push-pull machines, arc swing machines, flat swing machines, and eight-axis machines, and can realize automatic clamping and loading of small, medium and large diameter concave and convex optical glass. Background Technology

[0002] Currently, the processing of small, medium, and large diameter concave and convex glass relies on traditional cold working equipment with ejector pin mechanisms, which requires the use of clamping rings to complete the grinding process. However, there is a lack of automatic material handling devices with attached clamping rings, and manual operation is still required. This has the following four core drawbacks: 1. Extremely low processing efficiency: Only 15-20 pieces of glass with a diameter of 50mm can be processed per hour, and only 8-10 pieces of glass with a diameter of over 100mm can be processed per hour, which cannot meet the needs of mass production; 2. High labor intensity and high safety risks: Operators perform repetitive picking and placing actions more than 1,200 times a day, working 8-10 hours a day, which easily leads to muscle strain in the arms; the grinding wheel speed is 1,500-2,000 r / min, and the annual accident rate of glass shattering and flying glass and hand contact with the grinding wheel is 3%-5%; 3. Unstable processing accuracy: The coaxiality error between the glass and the collar and grinding wheel is 0.1-0.2mm, and the thickness deviation after grinding exceeds ±0.03mm, with a failure rate of 8%-12%, which cannot meet the high-end requirements; 4. High equipment upgrade costs: Existing automated loading and unloading devices are only suitable for glass with a diameter of 25mm or less, have a complex structure and high cost, and cannot process glass with a diameter of 30mm or more.

[0003] The limitations of existing technology are: 1. Lack of general-purpose automated solutions and equipment covering cold processing of optical glass with diameters ranging from 1mm to 150mm; 2. There is no automated loading and unloading device for older equipment with ejector pins, especially one that cannot be adapted without modifying the original equipment; 3. The equipment has poor versatility, only suitable for processing small-diameter glass, and cannot meet the needs of different sizes. Summary of the Invention

[0004] Addressing the pain points of existing technologies such as "manual operation, low efficiency, high risk, poor accuracy, and poor adaptability," this utility model provides a comprehensive and highly stable universal optical glass processing solution and suction / release device that is compatible with various types of equipment and glass specifications, ensures positioning accuracy, automates traditional processes, and reduces costs and risks. It is especially suitable for both new and old equipment with ejector pin mechanisms.

Detailed Implementation

[0013] The following description, in conjunction with the accompanying drawings, details the general-purpose optical glass processing suction and release device of this utility model.

[0014] This utility model discloses a universal optical glass processing suction and release device, applicable to optical glass cold processing equipment with ejector pins, such as push-pull machines, arc pendulum machines, flat pendulum machines, and eight-axis machines. It includes a basic support assembly and three replaceable glass suction and release modules. The basic support assembly includes a collar 5 made of metal / plastic material and a rotary cylinder 7. The inner diameter of the collar 5 matches the size of the glass 6. One side of the collar 5 has a groove for placing the glass 6, and the other side has a wear-resistant metal insert 15 embedded in its center. The tapered position of the insert 15 mates with the ejector pin 2. The rotary cylinder 7 has an adjustable rotation angle of 0-180°, a response time ≤0.3s, and a maximum load of 5kg, ensuring fast and stable pick-and-place operations to match the processing cycle of the equipment. The three replaceable glass suction and release modules are a double-layer suction cup module, a clamping suction module, and a magnetic suction module. These three modules are connected to the basic support assembly via standardized interfaces for quick replacement. Example 1

[0015] This utility model features a double-layer suction cup module; see [link / reference]. Figures 2 to 5The system includes a material-grabbing rod 8, double-layer suction cups 13, and a vacuum system. The material-grabbing rod 8 is mounted on a material-grabbing rod base 9. One end of the material-grabbing rod 8 is keyed to a rotary cylinder 7 and locked with an M5 set screw. The other end of the material-grabbing rod 8 is fixed to a suction cup mounting plate 10 with screws, ensuring the mounting plate's flatness is calibrated (≤0.03mm / m). Two double-layer suction cups 13 are mounted on the suction cup mounting plate 10 with hollow screws, ensuring airtight connection with the vacuum connector. The double-layer suction cups 13 are made of nitrile rubber and consist of inner and outer suction cups that are not interconnected. The inner suction cup holds the glass 6, and the outer suction cup holds the collar 5. A central suction hole 16 is provided in the center of the double-layer suction cup 13 for adsorbing the glass on the collar 5, and edge suction holes 17 are provided along the edges of the double-layer suction cup 13 for adsorbing the collar 5. The suction cup mounting plate 10 is provided with a central suction hole vacuum connector 11 communicating with the central suction hole 16 and an edge suction hole vacuum connector 12 communicating with the edge suction hole 17. The vacuum system includes the central suction hole vacuum connector 11 and the edge suction hole vacuum connector 12, and both vacuum connectors are connected to a vacuum source. A collar 5 next to the insert 15 is provided with a collar suction hole 14, so that the edge suction hole 17 can be directly aligned with the collar suction hole 14 when the double-layer suction cup 13 adsorbs.

[0016] Working process of the double-layer suction cup module: 1. Material preparation: The operator places the convex and concave glass to be processed into the designated position.

[0017] 2. Automatic Material Handling: The vacuum connector 12 at the edge suction hole is connected to the vacuum source, and the double-layer suction cup 13 adsorbs the collar 5. The rotary cylinder 7 drives the collar 5 so that the glass placement opening faces upward. The robotic arm picks up the glass and places it into the collar 5. The vacuum connector at the central suction hole is connected to the vacuum source, and the double-layer suction cup 13 simultaneously adsorbs the glass. The rotary cylinder 7 then drives the collar 5 to flip so that the insert 15 faces upward, and puts the glass 6 into contact with the grinding wheel 4 of the grinding vessel.

[0018] 3. Processing Start: Turn off the vacuum source, release the collar 5 and glass 6, and exit the material handling. Start the machine. The ejector pin bracket 1 drives the ejector pin 2 to move, so that the ejector pin 2 contacts the tapered hole of the insert 15 and presses down the insert 15. The grinding wheel spindle 3 rotates, so that the grinding wheel 4 processes the glass 6.

[0019] 4. Unloading and circulation: After processing, the ejector pin 2 is lifted, and the double-layer suction cup 13 picks up the collar 5 and the finished glass 6. At the same time, the glass to be processed is loaded (the two double-layer suction cups work together). Then the finished glass 6 is moved to the unloading position, the vacuum is closed and the unloading is performed. The system automatically circulates to realize the automatic suction and release of optical glass processing. Example 2

[0020] This utility model features a clamp-on module; see [link / reference]. Figures 6 to 8The system includes a material-picking rod 8, a Y-shaped finger clamping cylinder 20, grippers 22 at the output end of the clamping cylinder 20, and a vacuum system. The material-picking rod 8 is mounted on a material-picking rod base 9. One end of the material-picking rod 8 is connected to a rotary cylinder 7, and the other end is screwed to a cylinder mounting plate 19. The clamping cylinder 20 is fixed to the cylinder mounting plate 19 and is connected to a cylinder air pipe connector 18. The inner sides of the two grippers 22 of the clamping cylinder 20 have arc-shaped grooves matching the outer diameter of the collar 5. The bottom of the grooves of the grippers 22 has gripper suction holes 25. Correspondingly, the insert 15 of the collar 5 has insert suction holes 24, which extend to the bottom of the collar 5. After the two grippers 22 clamp the insert 15, the gripper suction holes 25 are directly opposite the insert suction holes 24. The gripper suction holes 25 are connected to a vacuum air pipe connector 21, which in turn is connected to a vacuum source. A 1.5mm thick silicone rubber sealing gasket 26 is provided on the contact surface between the jaws and the collar to ensure a tight seal when clamped.

[0021] Working process of clamp-on modules: 1. Material preparation: The operator places the convex and concave glass to be processed into the designated position.

[0022] 2. Automatic material handling: Clamping cylinder 20 clamps the insert 15 of collar 5, rotating cylinder 7 drives the collar glass placement opening upwards, and the robotic arm sucks the glass into the collar. At the same time, vacuum pipe connector 2 connects to the vacuum source, and the glass is adsorbed through the gripper suction hole 25. Rotating cylinder 7 then drives the collar insert upwards, and the ejector pin 2 contacts the tapered hole of insert 15. The ejector pin 2 presses down to make the glass 6 fit against the grinding wheel 4 of the grinding vessel.

[0023] 3. Processing Start: Release the gripper 22 and glass 6 to exit the material handling process. Start the machine; the grinding wheel spindle 3 rotates, causing the grinding wheel 4 to process the glass 6.

[0024] 4. Unloading and circulation: After processing is completed, the ejector pin 2 is lifted, the gripper 22 clamps and picks up the suction ring 5 and the finished glass, and at the same time, the other gripper loads the glass to be processed. Then the finished glass 6 is moved to the unloading position, the gripper is released, the vacuum is closed and the unloading is performed. The system automatically circulates to realize the automatic suction and release of optical glass processing. Example 3

[0025] This utility model features a magnetic suction module; see [link / reference]. Figure 9 and Figure 10The system includes a picking rod 8, an electromagnet 29, and a vacuum system. The picking rod 8 is mounted on a picking rod base 9, with one end connected to a rotary cylinder 7 and the other end connected to an electromagnet mounting plate 27. A DC electromagnet 29 is mounted on the electromagnet mounting plate 27. The electromagnet 29 has a rated voltage of 5-48V, a rated suction force of 5N, and no residual magnetic force. A through-hole magnet suction hole 32, communicating with the collar suction hole, is located in the middle of the electromagnet 29. The electromagnet mounting plate 27 has an electromagnet power cord hole 31 and a magnet suction hole vacuum connector 28 communicating with the magnet suction hole 32. The magnet suction hole vacuum connector 28 is connected to a vacuum source, and a 0.5mm² power cord passes through the electromagnet power cord hole 31. The electromagnet attracts and releases the metal collar 5, and the magnet suction hole 32 communicates with the collar suction hole 14 to attract and release glass. A nitrile rubber O-ring 30 is provided at the contact surface between the electromagnet 29 and the collar 5. The O-ring 30 prevents vacuum leakage at the contact surface between the electromagnet 29 and the collar 5.

[0026] Working process of magnetic modules: 1. Material preparation: The operator places the convex and concave glass to be processed into the designated position.

[0027] 2. Automatic material handling: Electromagnet 29 attracts the collar 5, and rotary cylinder 7 drives the collar to face upwards with the glass placement opening. The robotic arm picks up the glass and places it into the collar. At the same time, the vacuum connector 28 of the magnetic attraction hole is connected to the vacuum source, and the glass is attracted through the magnetic attraction hole 32. Rotary cylinder 7 then drives the collar insert to face upwards, and puts the glass 6 into contact with the grinding wheel 4 of the grinding vessel.

[0028] 3. Processing Start: Release the collar 5 and glass 6 to exit the material handling. Start the machine. The ejector pin bracket 1 drives the ejector pin 2 to move, so that the ejector pin 2 contacts the tapered hole of the insert 15 and presses down the insert 15. The grinding wheel spindle 3 rotates, so that the grinding wheel 4 processes the glass 6.

[0029] 4. Unloading and Circulation: After processing is completed, the ejector pin 2 is lifted, and the electromagnet 29 attracts the collar 5 and the finished glass. At the same time, another electromagnet attracts the glass to be processed. Then the finished glass 6 is moved to the unloading position. The electromagnet 29 is de-energized, the vacuum is closed and the unloading is performed. The system automatically circulates, realizing the automatic suction and release of optical glass processing.

[0030] This utility model is a general-purpose optical glass processing suction and release device suitable for processing concave and convex glass of all diameters. The collar fits tightly with the ejector pin of the original equipment with ejector pin mechanism, without the need to modify the original equipment.
