Description

Technical Field

[0001] This utility model relates to the field of spectacle lens processing technology, specifically to a spectacle lens printing and machining machine. Background Technology

[0002] During lens manufacturing, the lens first needs to be turned to achieve the desired shape. After turning, a mark needs to be printed on one of the lenses. Because cutting and printing are separate processes, the product is manually fixed on a lathe for turning, collected after processing, and then placed on a printing machine for printing. This process requires manual replacement midway, wasting labor and resulting in low efficiency. To overcome these problems, Chinese invention patent application CN202210703766.0 discloses "A White Lens Turning and Printing Integrated Machine" (publication date 2023.04.14), which can efficiently perform turning and printing on products. For products that do not require printing, they can be unloaded and collected after cutting.

[0003] However, the above equipment uses a stacked storage method for lens blanks, and then the feeding mechanism sends the stacked lens blanks one by one to the turning machine for turning. During the feeding process, the height of the stacked lens blanks will decrease layer by layer. The cylinder-type feeding mechanism used is difficult to adapt to the height difference of the lens blanks. In order to meet the adsorption requirements of the lower layer of lens blanks, a large stroke is required. As a result, the blanks are easily crushed when grabbing the upper layer of blanks, resulting in losses. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Please see Figure 1 The eyeglass lens machining and printing integrated machine includes a frame 01 and a machining mechanism A and a pad printing mechanism B set on the frame 01. The frame 01 is also equipped with a feeding mechanism C, a discharging mechanism D, and a feeding mechanism that picks up lens blanks from the feeding mechanism C and sequentially feeds them to the machining mechanism A, the pad printing mechanism B, and the discharging mechanism D.

[0033] The turning mechanism A includes a turning turntable A1 rotatably mounted on the frame 01 and a turning head A2 mounted on the frame 01. As the turning turntable A1 rotates, it is provided with a turning loading station, a turning processing station, and a turning unloading station in sequence. The turning turntable A1 is provided with three rotating suction cups A3 arranged in an equilateral triangle and rotatably connected to the turning turntable A1, corresponding to the turning loading station, the turning processing station, and the turning unloading station.

[0034] The feeding mechanism includes, in sequence, a turning loading mechanism E, a turning unloading mechanism F, a pad printing loading mechanism G, a pad printing conveying mechanism H, a pad printing unloading mechanism J, and a discharge receiving mechanism K.

[0035] This invention sets up a turning loading station, a turning processing station, and a turning unloading station on a turning turntable A1 in sequence. As the turning turntable A1 rotates, the lens blank completes the loading, processing, and unloading processes in sequence, reducing standby time and improving production efficiency.

[0036] The feeding mechanism C includes a feeding tray C1 and a feeding motor C2 mounted on the frame 01. The feeding tray C1 has a push hole C11, and a push block C3 driven by the feeding motor C2 pushes upward through the push hole C11. Columns C12 are arranged around the push hole C11 on the feeding tray C1 to form a rack for stacking lens blanks. Specifically, as shown in the figure, a push-lifting guide rail C4 is fixedly mounted on the frame 01. A sliding plate C5 is slidably connected to the push-lifting guide rail C4. The feeding motor C2 is fixedly mounted on the sliding plate C5. A nut seat C6 is fixedly mounted on the frame 01. A lead screw C7, threadedly engaged with the nut seat C6, connects the shaft of the feeding motor C2 and the push block C3. During machine operation, the feeding motor C2 pushes the pusher block C3 upward to lift the lens blank on the feeding tray C1, filling the height difference after material removal, ensuring that the turning feeding mechanism E can remove material under the same stroke, which is convenient for control and avoids damage to the lens blank under large stroke pressure.

[0037] Furthermore, the feed tray C1 has multiple evenly distributed material racks around its center, and the feed tray C1 is rotatably coupled with the frame 01. The feed switching motor C8, which drives the feed tray C1 to rotate, is fixedly installed on the frame 01. The multiple material racks on the feed tray C1 facilitate the operator to replenish lens blanks on unoccupied racks at any time during machine operation, ensuring continuous machine operation.

[0038] Furthermore, a movable block C13 is fixedly connected to the bottom end of the column C12. The movable block C13 is provided with a strip-shaped adjustment hole C131. The feed plate C1 is provided with a positioning screw that passes through the adjustment hole C131 and is threadedly connected to the feed plate C1, so as to flexibly adjust the width of the material rack to adapt to different sizes of lens blanks.

[0039] Furthermore, the turning loading mechanism E includes a turning loading guide rail E1 connected between the feeding mechanism C and the turning loading station, and a turning loading rotary cylinder E2 that moves along the turning loading guide rail E1.

[0040] The turning blanking mechanism F includes a turning blanking guide rail F1 connected to the turning blanking station and a turning blanking rotary cylinder F2 that moves along the turning blanking guide rail F1. A turning blanking suction cup F3 is fixedly connected to the rotating arm of the turning blanking rotary cylinder F2. Specifically, the turning blanking lifting cylinder E3 of the turning loading mechanism E drives the turning blanking suction cup E4 to descend. After the turning blanking suction cup E4 picks up the lens blank, the turning blanking lifting cylinder E3 drives the turning blanking suction cup E4 to rise. The turning blanking rotary cylinder E2 moves along the turning loading guide rail E1 and drives the turning blanking lifting cylinder E3 to the turning loading station. The turning blanking rotary cylinder E2 drives its rotating arm to rotate, causing the turning blanking lifting cylinder E3 to rotate 90°. The turning blanking lifting cylinder E3 delivers the lens blank to the turning blanking station. The rotary chuck A3 at the cutting and loading station completes the turning and loading action, and then returns to the feeding mechanism C to repeat the above action to achieve continuous loading; the turning turntable A1 rotates 120° to bring the lens blank to the turning processing station. After the turning processing is completed, the turning turntable A1 rotates 120° again to bring the processed lens to the turning unloading station. The turning unloading mechanism F grabs the lens and sends it to the pad printing loading mechanism G. The turning turntable A1 rotates 120° again to bring the empty rotary chuck A3 back to the turning and loading station to start turning and loading again.

A pad printing unloading suction cup J3 is fixedly connected to the telescopic rod of the pad printing unloading lifting cylinder J2.

[0044] Specifically, the pad printing lifting cylinder G2 drives the pad printing chuck G3 to pick up the lens from the turning unloading mechanism F and move along the pad printing lifting guide rail G1 to transfer the lens to the pad printing conveying chuck H3 on the pad printing conveying lifting cylinder H2. The pad printing conveying lifting cylinder H2 moves along the pad printing conveying guide rail H1 and pauses when it passes the pad printing mechanism B to complete the pad printing work. Then it continues to move to the end of the pad printing conveying guide rail H1 to wait for the unloading receiving mechanism K to pick up the lens.

[0045] Furthermore, the material receiving mechanism K includes a material receiving platform K1, on which a material receiving guide rail K2 is connected between the pad printing feeding mechanism J and the material receiving mechanism D, and a material receiving cylinder K3 that moves along the material receiving guide rail K2. A material receiving suction cup K4 is fixedly connected to the telescopic rod of the material receiving cylinder K3. Specifically, the pad printing feeding mechanism J first moves the lens onto the material receiving platform K1, and then the material receiving cylinder K3 drives the material receiving suction cup K4 to pick up the lens and move it to the material receiving mechanism D to complete the material receiving.

[0046] Furthermore, the pad printing mechanism B includes a pad printing frame B1 fixed on the frame 01 and a pad printing head B2 that moves back and forth on the pad printing frame B1. An ink-dipping table B3 is fixed on the pad printing frame B1, and an ink storage head B4 is also provided on the pad printing frame B1 that moves back and forth with the pad printing head B2 and scrapes the ink-dipping table B3.

[0047] Furthermore, the discharge mechanism D includes a discharge belt D1 and a discharge stacking mechanism D2 located at the tail end of the discharge belt D1.

This is a conventional technical means for mechanical products and will not be elaborated here.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
