[0002] Glasses are an essential tool for myopic people when traveling. With the continuous improvement of people's living standards, people's requirements for glasses are getting higher and higher. In order to improve the appearance beauty of glasses and the smoothness during the opening and closing of glasses, it is necessary to finely carve the connection end between the temple and the frame. The main principle is to place the temple on a fixture and polish the end of the temple through a polishing element. In the prior art, usually, the feeding and discharging work is manually carried out by workers. This not only has low efficiency, greatly increases the labor cost, but also there is a risk of injury to workers during the feeding process. In addition, after the feeding is completed, the temple may not be fed in place, which will lead to insufficient processing accuracy and even the appearance of defective products. Therefore, a new feeding device is needed. Summary of the Invention

The baffle plate is located directly above the conveyor belts and at the end of the conveyor belts close to the fixed fixture. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the first rotating motor, the second rotating motor, the driving motor, and the clamping element respectively.

[0005] With the above technical solution, first, place the temple to be processed on the conveyor belt, and then control the driving motor through the controller to drive the conveyor belt to move, so that the temple moves in the direction of the clamping element. When the temple moves to the position of the baffle, control the third hydraulic cylinder through the controller to drive the baffle to move vertically downward to ensure that the feeding position of the temple remains consistent. Then, control the first hydraulic cylinder and the second hydraulic cylinder through the controller to drive the second connecting base to move horizontally and drive the third connecting base to move vertically, respectively, so that the position of the clamping element corresponds to the position of the temple. Then, control the clamping element to clamp the temple through the controller, and then control the first rotating motor through the controller to drive the first connecting base to rotate a certain angle, so that the clamping element moves to directly above the limit groove, and then place the temple in the limit groove through the clamping element. Then, perform fine carving work. After completing the fine carving work, control the first hydraulic cylinder and the second hydraulic cylinder through the controller to drive the second connecting base and the third connecting base to move a certain distance, so that the clamping element moves to directly above the limit groove, and then control the clamping element to clamp out the processed temple through the controller.

[0007] With the above technical solution, since the optoelectronic signal emitted by the optoelectronic sensor corresponds to the position of the baffle, when the temple is transmitted to the corresponding position of the baffle through the conveyor belt, the optoelectronic sensor sends an electrical signal to the controller. The controller controls the driving motor to stop working. At the same time, the controller controls the third hydraulic cylinder to drive the baffle to move vertically downward, which can further ensure the accurate position of the temple during feeding, and then ensure the accurate processing position of the temple and improve the processing accuracy. Further setting of the present utility model: The clamping element includes a plurality of vacuum suction cups fixedly connected to the third connecting base, a connecting pipe connected to the vacuum suction cups, and a vacuum pump connected to the connecting pipe. Every two vacuum suction cups form a vacuum suction cup group.

The vacuum pump is electrically connected to the controller.

[0008] With the above technical solution, the controller controls the vacuum pump to provide suction for the vacuum suction cups, so that the vacuum suction cups suck the temple, which can avoid the temple being clamped and damaged by the clamping element during the feeding process.

The cross-sectional shape of the first communication groove is the same as the cross-sectional shapes of the third sliding base and the second connection groove in terms of size. The controller is electrically connected to the third hydraulic cylinder, the fourth hydraulic cylinder, and the third rotating motor respectively.

[0010] With the above technical solution, after the temple is completed with fine carving work, the controller controls the third hydraulic cylinder to drive the first sliding base to move horizontally, so that the third sliding base moves to directly below the first communication groove and the second connection groove. Then, the controller controls the fourth hydraulic cylinder to drive the third sliding base to move vertically upward. Since the cross-sectional shape of the first communication groove is the same as the cross-sectional shapes of the third sliding base and the second connection groove in terms of size, the third sliding base will push the temple out of the limiting groove. Then, the controller controls the third hydraulic cylinder to drive the first sliding base to reset. Then, the controller controls the third rotating motor to drive the rotating shaft to rotate a certain angle, so that the temple falls into the discharging bin. Then, the controller controls the fourth hydraulic cylinder to drive the third sliding base to reset. This can improve the discharging efficiency and reduce the movement stroke of the clamping element. Description of the Drawings

The controller 5 is electrically connected to the first hydraulic cylinder 16, the second hydraulic cylinder 17, the first rotating motor 15, the second rotating motor 18, the driving motor 10, and the gripping element 14 respectively.

[0015] First, place the temple to be processed on the conveyor belt 8, and then control the driving motor 10 through the controller 5 to drive the conveyor belt 8 to move, so that the temple moves in the direction of the clamping element 14. When the temple moves to the position of the baffle 9, control the third hydraulic cylinder through the controller 5 to drive the baffle 9 to move vertically downward to ensure that the feeding position of the temple remains consistent. Then, control the first hydraulic cylinder 16 and the second hydraulic cylinder 17 through the controller 5 to drive the second connecting base 12 to move horizontally and drive the third connecting base 13 to move vertically, so that the position of the clamping element 14 corresponds to the position of the temple. Then, control the clamping element 14 to clamp the temple through the controller 5. Then, control the first rotating motor 15 through the controller 5 to drive the first connecting base 11 to rotate a certain angle, so that the clamping element 14 moves directly above the limiting groove 7. Then, place the temple in the limiting groove 7 through the clamping element 14. Then, carry out the fine carving work. After the fine carving work is completed, control the first hydraulic cylinder 16 and the second hydraulic cylinder 17 through the controller 5 to drive the second connecting base 12 and the third connecting base 13 to move a certain distance, so that the clamping element 14 moves directly above the limiting groove 7. Then, control the clamping element 14 to clamp out the processed temple through the controller 5. This can greatly improve the feeding efficiency. At the same time, it can avoid hand injuries when the staff manually picks up the temple.

[0016] An optoelectronic sensor 19 is provided on the equipment base 1. The optoelectronic signal emitted by the optoelectronic sensor 19 corresponds to the position of the baffle 9. The controller 5 is electrically connected to the optoelectronic sensor 19.

[0017] Since the optoelectronic signal emitted by the optoelectronic sensor 19 corresponds to the position of the baffle 9, when the temple is transmitted to the corresponding position of the baffle 9 through the conveyor belt 8, the optoelectronic sensor 19 sends an electrical signal to the controller 5. The controller 5 controls the driving motor 10 to stop working. At the same time, the controller 5 controls the third hydraulic cylinder to drive the baffle 9 to move vertically downward, which can further ensure the accurate position of the temple during feeding, and then ensure the accurate processing position of the temple and improve the processing accuracy.

The vacuum pump 22 is electrically connected to the controller 5.

[0019] The vacuum pump 22 is controlled by the controller 5 to provide suction force for the vacuum chuck 20, so that the vacuum chuck 20 sucks the temple, which can avoid the temple being clamped and damaged by the clamping element 14 during the feeding process.

[0020] It further includes a discharging device 24. The discharging device 24 includes a first sliding base 25 slidably connected to the equipment base 1, a rotating shaft 26 movably connected to the first sliding base 25, a second sliding base 27 fixedly connected to the rotating shaft 26, a third sliding base 28 slidably connected to the second sliding base 27, a discharging bin 29 fixedly connected to the equipment base 1, a third hydraulic cylinder 30 for driving the first sliding base 25 to move horizontally, a fourth hydraulic cylinder 31 for driving the third sliding base 28 to move vertically, and a third rotating motor 32 for driving the rotating shaft 26 to rotate. The discharging bin 29 is located below the third sliding base 28. A first communication groove 33 penetrating the fixture base 6 is provided on the fixture base 6, and a second connection groove penetrating the workbench 2 is provided on the workbench 2. The positions of the first communication groove 33 and the second communication groove 34 correspond to each other. The first communication groove 33 is communicated with the limiting groove 7. The width of the first communication groove 33 is smaller than the width of the limiting groove 7. The cross-sectional shape of the first communication groove 33 is the same as the cross-sectional shape of the third sliding base 28 and the cross-sectional shape of the second communication groove 34. The controller 5 is electrically connected to the third hydraulic cylinder 30, the fourth hydraulic cylinder 31, and the third rotating motor 32 respectively.

[0021] When the temple is finished with the fine carving work, the controller 5 controls the third hydraulic cylinder 30 to drive the first sliding base 25 to move horizontally, so that the third sliding base 28 moves to directly below the first communication groove 33 and the second communication groove 34. Then the controller 5 controls the fourth hydraulic cylinder 31 to drive the third sliding base 28 to move vertically upward. Since the cross-sectional shape of the first communication groove 33 is the same as the cross-sectional shape of the third sliding base 28 and the cross-sectional shape of the second communication groove 34, the third sliding base 28 will push the temple out of the limiting groove 7. Then the controller 5 controls the third hydraulic cylinder 30 to drive the first sliding base 25 to reset. Then the controller 5 controls the third rotating motor 32 to drive the rotating shaft 26 to rotate a certain angle, so that the temple falls into the discharging bin 29. Then the controller 5 controls the fourth hydraulic cylinder 31 to drive the third sliding base 28 to reset. This can improve the discharging efficiency and reduce the movement stroke of the clamping element 14.
