Description

Technical Field

[0001] The invention belongs to the field of optical processing equipment, and in particular relates to an automatic loading and unloading system for optical lenses of a horizontal edge grinding machine with simple structure, high production efficiency, good stability, safety and reliability, and a horizontal edge grinding machine. Background Art

[0002] Optical lens edge grinding machine is a kind of fine processing equipment that processes the edge of optical lens to improve the size and angle accuracy of optical lens, improve the edge characteristics of lens, and solve the burrs, cracks and glue overflow on the edge of lens production. Therefore, edge grinding machine is also an indispensable and important equipment in optical lens processing.

[0003] At present, optical lens edge grinding machines include manual edge grinding machines, flat and special-shaped edge grinding machines plus beveling edge grinding machines, and CNC edge grinding machines. Manual edge grinding machines mainly rely on the guide column attached to the grinding wheel to guide, and the grinding feed and grinding direction are manually adjusted to complete the edge grinding. Not only is the labor intensity high and the production efficiency low, but also factors such as operator proficiency and strength will affect the edge grinding quality, resulting in unstable product quality. Flat and special-shaped edge grinding machines need to be used together with beveling edge grinding machines to complete contour grinding and chamfering respectively. Not only is the equipment cost high and the floor space is large, but the processing procedures are also complicated, and the products after edge grinding will have edges and corners. CNC edge grinding machines can complete three-dimensional edge grinding, achieving grinding and chamfering at the same time; but they require four-axis linkage, and the equipment manufacturing cost, use cost and maintenance cost are very high. In addition, although the grinding principles, grinding efficiency and grinding quality of the above-mentioned edge grinders are different, most of them still require manual direct or auxiliary loading and unloading, which is not only labor-intensive, but also easy to collide with the chuck when manually taking and placing the lens, resulting in safety hazards and poor edge grinding quality. The edge grinding operation requires the use of edge grinding oil, which will also cause harm to the operator, and the labor cost is expensive, the operation efficiency is low, the consistency is poor, the quality is unstable, and the defect rate is high. For this reason, there are also multi-axis robots in the prior art to achieve automatic loading and unloading, but their structure is complex and expensive, and the later maintenance is also difficult. Moreover, the robot loading and unloading requires two round trips to complete, resulting in the edge grinder needing to wait idly from unloading to loading, making it difficult to improve production efficiency. In addition, there are also loading and unloading technical solutions using a vertical and horizontal structure in the prior art. Although the structure is simpler and easier to maintain than a multi-axis robot, there are also problems that the vertical and horizontal structure occupies a large area and the lens is difficult to center. Direct application will cause unstable edge grinding quality, and in order to improve the quality, an automatic centering mechanism must be added to complicate the structure and maintenance, so it can only be used for edge grinding of low-end lenses. Summary of the invention

[0004] The object of the present invention is to provide an automatic loading and unloading system for optical lenses of a horizontal edge grinding machine and a horizontal edge grinding machine which have simple structure, high production efficiency, good stability, safety and reliability.

[0005] The automatic loading and unloading system of optical lenses of the horizontal edge grinding machine of the present invention is realized as follows: it includes a frame, a material tray, a feeding device, a material taking device, a feeding and taking device, and a controller. The frame is fixedly arranged on one side of the horizontal edge grinding machine, and the controller is fixedly arranged on the frame.

[0006] The feeding device comprises a material guide trough and a pushing mechanism. The material guide trough is parallel to the grinding spindle of the horizontal edge grinder and is arranged on the side of the outer end of the frame away from the grinding wheel. The bottom of the material guide trough is provided with a longitudinally extending long hole and the lower part of the side wall near the grinding side is provided with a plate outlet. The material trays are stacked and arranged in the material guide trough. The pushing mechanism is arranged at the bottom of the material guide trough and the feeding push rod extends into the long hole and pushes the material trays to move step by step out of the plate outlet.

[0007] The material taking device comprises a vertical moving mechanism, a guide frame, and a rotating mechanism. The body of the vertical moving mechanism is vertically fixedly arranged on a frame outside the plate outlet. The guide frame is vertically fixedly arranged on a frame on the side of the moving end of the vertical moving mechanism. One end of the rotating mechanism is connected to the moving end and is also slidably connected to the guide groove or guide rod of the guide frame. A suction cup I is arranged on the top of the rotating rod of the rotating mechanism. The suction cup I is connected to the vacuum system through a control valve I.

[0008] The feeding device includes a rotating base, a mechanical arm, and a two-finger clamp. The rotating base is rotatably arranged on a frame between the feeding device and the grinding spindle of the horizontal edge grinder. The rotating axis of the rotating base is parallel to the grinding spindle of the horizontal edge grinder. One end of the mechanical arm is vertically fixedly connected to the rotating axis of the rotating base. The two-finger clamp is arranged at the other end of the mechanical arm and is connected to the vacuum system through the control valve II or connected to the power supply through the control switch I.

[0009] The pushing mechanism, the vertical moving mechanism, the rotating base, and the control ends of the control valve I, the control valve II, and the control switch I are electrically connected to the controller respectively.

[0010] The horizontal edge grinding machine of the present invention is realized as follows: it includes an automatic loading and unloading system for optical lenses of the aforementioned horizontal edge grinding machine.

[0011] Beneficial effects of the present invention:

[0012] 1. The present invention connects the feeding device, the taking device and the feeding and taking device in sequence, and can realize the sharing of the same material tray for loading and unloading through forward loading and reverse unloading, and can also realize automatic tray replacement of stacked material trays, and can also reduce the problems of traditional manual loading and unloading and the vertical and horizontal loading and unloading structure in the prior art requiring two material trays, resulting in excessive floor space, as well as the need for manual disassembly and replacement of material trays for manual loading and unloading and manual assistance in changing material trays for vertical and horizontal loading and unloading. Not only is the structure simple and compact, but it also reduces labor intensity and improves, and also effectively avoids the adverse effects of manual operation on quality, and can also realize one person to manage multiple edge grinding machines, effectively improving production efficiency and quality stability.

[0013] 2. The present invention realizes automatic loading and unloading of materials through a feeding device, a picking device and a feeding and picking device. Manual operation only requires changing the material tray at regular intervals. Compared with robots, the structure is simpler, easier to maintain and lower in cost. Moreover, compared with traditional manual operations, personal injury can be avoided, thereby effectively improving the safety of edge grinding operations. In particular, by adding a transfer mechanism, while the suction cup II of the transfer mechanism adsorbs the lens to be ground, the feeding and picking device can take out the edged lens and pass it to the suction cup I of the picking device, thereby transferring the lens to be ground from the suction cup II to the edge grinder, effectively realizing the cross-connection of the loading and unloading processes, shortening the idling time of the edge grinder during loading and unloading, and effectively improving the edge grinding production efficiency.

[0014] 3. The material picking device and transfer mechanism of the present invention use suction cups to absorb the lens, while the feeding and picking device uses pneumatic clamping of the lens, which can avoid damaging the lens during the absorption and clamping process. In addition, the feeding device, the material picking device, the transfer mechanism and the feeding and picking device are driven by oil pressure or pneumatic drive, so the torque of the loading and unloading movement is relatively large, which makes the positioning accuracy of the loading and unloading higher, which is beneficial to improving the edge grinding quality of the lens.

[0015] In summary, the present invention has the characteristics of simple structure, high production efficiency, good stability, safety and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The optical lens horizontal edge grinding machine of the present invention comprises the optical lens automatic loading and unloading system of the aforementioned horizontal edge grinding machine.

[0046] The working principle and working process of the present invention:

[0047] like Figures 1 to 8 As shown, after the present invention is started, it works according to the following steps after the self-check is completed:

[0048] 1. Place the optical lens to be edged in the conical hole 2B of the long strip material tray 2 and automatically center it, then take the optical lens and the material tray 2 and stack them in the guide groove 3, the controller controls the piston rod 4B of the cylinder Ⅰ (i.e., the pushing mechanism 4) to retract, drive the ratchet mechanism 4C at the top of the piston rod 4B to get stuck and make the feeding push rod 4A get stuck in the feeding groove or feeding hole on the lower surface of the tray body 2A, and pull the material tray 2 and the optical lens to be edged therein to the loading and unloading position outside the tray outlet 3A; then control the piston rod 4B of the cylinder 4 to extend, the ratchet mechanism 4C at the top of the piston rod 4B of the feeding push rod 4A rotates due to the obstruction of the material tray 2, and the feeding push rod 4A rotates a certain angle to disengage from the material tray 2, and then the feeding push rod 4A moves with the piston rod 4B to the bottom of the next conical hole 2B of the material tray 2 to wait, completing the feeding process of the material tray 2 of the optical lens to be edged.

[0049] 2. After the optical lens to be edged in the material tray 2 is sent to the loading and unloading position, the controller controls the piston rod 5B of the cylinder II (i.e., the vertical moving mechanism 5) to extend, thereby driving the slider 7B to slide down along the guide groove or guide rod of the guide frame 6, and the rotating rod 7A moves downward and rotates from a horizontal position to a vertical position under the action of the torsion spring 7D1 or the tension spring 7D2. Finally, the suction cup I8 at the top of the rotating rod 7A abuts against the lens to be edged in the material tray 2, and then the control valve I is controlled to connect the suction cup I8 to the vacuum system to suck the lens to be edged; then the piston rod 5B of the control cylinder 5 is retracted, driving the slider 7B to move up along the guide groove or guide rod of the guide frame 6, and when the rotating rod 7A moves to the top, due to the obstruction of the end face by the stopper 7C, the rotating rod 7A rotates from a vertical position to a horizontal position, completing the material removal and reversal of the lens to be edged.

[0050] 3. The controller controls the reciprocating mechanism 12 to extend the mobile end, and then controls the rotating base 9 to rotate so that the two-finger gripper 11 on the robot arm 10 rotates to the top of the suction cup Ⅰ8. Then the reciprocating mechanism 12 retracts the mobile end to move the two-finger gripper 11 to the sides of the optical lens of the suction cup Ⅰ8, controls the two-finger gripper 11 to clamp the optical lens on the suction cup Ⅰ8, and then cuts off the vacuum system connected to the suction cup Ⅰ8, and transfers the lens to be edged to the two-finger gripper 11 (in the middle of the lens edge grinding connection, and controls the reciprocating mechanism 12 to extend the mobile end so that the optical lens clamped by the two-finger gripper 11 abuts against the suction cup Ⅱ14, and then controls the control valve Ⅱ to connect the suction cup Ⅱ14 with the vacuum system, and at the same time controls the two-finger gripper 11 to connect the two-finger gripper 11 to the suction cup Ⅱ14. The clamping jaw 11 is released to transfer the lens to be edged onto the suction cup II 14, and the two-finger clamping jaw 11 transfers the ground lens onto the suction cup I8, and then the lens to be ground is obtained from the suction cup II 14); then the reciprocating mechanism 12 is controlled to move the two-finger clamping jaw 11 holding the lens to be edged to the edge grinding loading position, and then the rotating base 9 is controlled to rotate so that the two-finger clamping jaw 11 on the robot arm 10 rotates the lens to the coaxial position of the grinding spindle, and the reciprocating mechanism 12 is controlled to retract the moving end to abut the lens against the grinding head, and the two-finger clamping jaw is released after the grinding push rod is pressed against the lens on the grinding head, and then the rotating base 9 is controlled to rotate so that the robot arm 10 returns to the standby position, completing the loading process of the lens to be ground.

[0051] 4. After the edge grinding is completed, the controller controls the rotating base 9 to rotate so that the robot arm 10 rotates the two-finger clamp 11 to the two sides of the ground lens on the grinding head, controls the two-finger clamp 11 to clamp the ground lens and release the grinding top rod at the same time, then controls the reciprocating mechanism 12 to extend the mobile end to make the lens separate from the grinding head, then controls the rotating base 9 to rotate so that the robot arm 10 rotates the ground lens on the two-finger clamp 11 to be coaxial with the suction cup Ⅰ8, then controls the reciprocating mechanism 12 to retract the mobile end to make the lens abut against the suction cup Ⅰ8, connects the suction cup Ⅰ8 to the vacuum system and releases the two-finger clamp 11, transfers the ground lens to the suction cup Ⅰ8, and the ground lens rotates with the suction cup Ⅰ8 and moves downward to the material tray 2 below, completing the unloading process of the ground lens.

[0052] 5. After all the lenses in the previous tray 2 have been ground, they move to the receiving trough 15 under the push of the next tray 2. When the tray 2 moves and completely falls into the receiving trough 15, the sensor is triggered to start the lifting mechanism 16 to move the receiving trough 15 down to the height of one tray 2, so that the receiving trough 15 continues to receive the next tray 2. When the lifting mechanism 16 drops to the preset height, the sound and light alarm device is triggered to alarm and wait for the staff. The staff starts the reset switch of the lifting mechanism 16, and the lifting mechanism 16 rises to facilitate the staff to take out the tray 2 in the receiving trough 15. If the staff does not reset it, the entire device will automatically stop waiting and continue to alarm. The alarm for the last tray in the guide trough 3 is similar to the receiving trough 15.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
