Detailed Implementation

[0018] The following is in conjunction with the appendix Figs. 1 to 3 This utility model will be described in detail.

[0019] This utility model discloses an improved lens feeding structure for a precision engraving machine, comprising a material conveying device 1 and a processing device 2. The material conveying device 1 is equipped with a lens transport table 11, and a first lifting device 12 is provided below the lens transport table 11. The lens transport table 11 is equipped with a lens fixing plate 111, and a lens groove 112 is provided on the lens fixing plate 111 for placing lenses. The lens transport table 11 is also equipped with a conveyor belt 13 for moving the lens fixing plate 111. The processing device 2 is equipped with a precision engraving head 21 and a mechanism for driving the precision engraving head 21 to rise and fall. The guide rail mechanism enables lateral and longitudinal movement. A material handling device 3 is provided between the material conveying device 1 and the processing device 2. The material handling device 3 is equipped with a tray 31, and an adsorbent 32 for gripping and fixing lenses is provided on the tray 31. The material handling device 3 is equipped with a first motor 33. One end of the tray 31 is fixedly connected to the rotating shaft of the first motor 33. The first motor 33 can drive the tray 31 to swing between the material conveying device 1 and the processing device 2. The adsorbent 32 is externally connected to a vacuum pump or other equipment that can generate negative pressure, so that the adsorbent 32 can adsorb and grip the lenses. In use, the first lifting device 12 drives the lens transport table 11 to descend, allowing the conveyor belt 13 inside the lens transport table 11 to cooperate with the conveying components of other transport mechanisms. The lens fixing plate 111 is transported from other transport mechanisms to the lens transport table 11. Then, the first lifting device 12 drives the lens transport table 11 to rise to the designated position. Then, the first motor 33 drives the pallet 31, so that the pallet 31 covers the lens fixing plate 111. The suction device 32 grips the lens placed in the lens slot 112 downwards. Then, the first motor 33 drives the pallet 31 to rotate 180°, so that the lens gripped by the suction device 32 rotates 180° and moves into the processing device 2. After that, the precision engraving head 21 performs cutting processing on the lens. The material handling device 3 of this utility model can automatically and quickly transport the lens from the material handling device 1 to the processing device 2 for lens precision engraving processing, improving the lens feeding speed.

[0020] Limiting plates 14 are provided on both sides of the lens transport table 11, and the lens fixing plate 111 is placed between the two limiting plates 14. In this design, there is a certain height difference between the top of the conveyor belt 13 and the top of the lens transport table 11. The two limiting plates 14 cooperate with the conveyor belt 13 to form a groove, which facilitates the placement of the lens fixing plate 111 and at the same time orients the lens fixing plate 111 to avoid tilting or misalignment.

[0021] The lens transport table 11 is internally equipped with a second motor 15 for driving the conveyor belt 13. The second motor 15 is a servo motor, which can drive the conveyor belt 13 in both forward and reverse directions. In specific use, other transport mechanisms for transporting the lens fixing plate 111 can be set at different heights. When the lens fixing plate 111 brings in an unfinished lens, the first lifting device 12 drives the lens transport table 11 to a first height position, and the conveyor belt 13 rotates in the forward direction, moving the lens fixing plate 111 from the other transport mechanism at the first height position to directly above the lens transport table 11. After the lens is finished being finely cut, the pallet 31 flips over, placing the lens back into the lens slot 112. Then, the first lifting device 12 drives the lens transport table 11 to a second height, and the conveyor belt 13 rotates in the reverse direction, moving the lens fixing plate 111 from directly above the transport table to the other transport mechanism at the second height position for unloading.

[0022] The guide rail mechanism is provided with a fixed frame 22, and a second lifting device 23 is provided on the fixed frame 22. The engraving head 21 is installed below the second lifting device 23. The second lifting device 23 can drive the engraving head 21 to rise and fall, so that the engraving head 21 can move along the Z-axis.

[0023] Similarly, the fixed frame 22 is provided with a first guide rail 24, and the second lifting device 23 is provided with a slider 25 that is movably connected to the first guide rail 24. The second lifting device 23 can move laterally along the first guide rail 24, so that the engraving head 21 can move along the Y-axis.

[0024] Similarly, a base 4 is provided below the fixed frame 22. The base 4 is sequentially provided with a second guide rail 41 perpendicular to the first guide rail 24, a lead screw 42 parallel to the second guide rail 41, and a third motor 43 that drives the lead screw 42 to rotate. The fixed frame 22 is movably connected to the second guide rail 41, and the fixed frame 22 is also provided with a threaded sleeve 26 threadedly connected to the lead screw 42. The third motor 43 can drive the fixed frame 22 to move along the second guide rail 41, allowing the engraving head 21 to move along the X-axis.

[0025] The tray 31, in conjunction with the suction unit 32, can automatically fix the lens under the engraving head 21. The lens can be directly cut and processed by the engraving head 21 on the tray 31, reducing the lens positioning and fixing steps and improving production efficiency. More specifically, the material handling device 3 is equipped with a support block 34 for supporting the tray 31. After the tray 31 is tilted to the processing device 2, the support block 34 can hold the tray 31 in place, keeping the tray 31 horizontal and improving stability.

[0026] The tray 31 is provided with several adjustment slots 35, and the adsorbers 32 are installed in the adjustment slots 35. Multiple adsorbers 32 are provided on the tray 31, and these adsorbers 32 work together to adsorb and grip a single lens, facilitating more stable gripping and fixing of the lens. The position of the adsorbers 32 can be adjusted within the adjustment slots 35, thereby adjusting the spacing between the adsorbers 32 to facilitate gripping lenses of various sizes.

[0027] The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this invention, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. 。
