[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-5 As shown, this utility model discloses an automatic feeder for a four-head automatic processing machine for eyeglass lenses, which can accurately position eyeglass lenses and perform cutting and chamfering on the lenses.

[0036] like Figure 1-2As shown, this utility model designs an automatic feeder for a four-head automatic processing machine for eyeglass lenses. It mainly includes an operating table 1, on which a control bracket 3 and a conveying device 2 are installed. The conveying device 2 includes an eyeglass lens feeding conveyor belt 21 and an eyeglass lens recycling conveyor belt 22. The control bracket 3 includes a lifting control slide 31 and a lifting movable plate 32. A loading module bracket 4 and a recycling module bracket 5 are installed on the lifting movable plate 32. The eyeglass lens feeding conveyor belt 21 transports the eyeglass lenses to the area below the loading module bracket 4, allowing the loading module bracket 4 to pick up the lenses and feed them onto the processing device. After processing is completed, the recycling module bracket 5 picks up the processed eyeglass lenses and transfers them to the eyeglass lens recycling conveyor belt 22 for the next process.

[0037] Automating the processing and transfer of eyeglass lenses reduces manual operations, minimizes errors, and improves overall processing efficiency.

[0038] Specifically, such as Figure 2-4 As shown, since the lifting control slide 31 needs to control the vertical movement of the lifting movable plate 32, and the lifting movable plate 32 is equipped with the feeding module bracket 4 and the recycling module bracket 5, the overall weight is very heavy. Therefore, it is necessary to increase the power of the lifting control slide 31 or reduce the burden on the lifting control slide 31. This utility model adopts a counterweight balance method to reduce the burden on the lifting control slide 31.

[0039] Specifically, such as Figures 3-4 As shown, a counterweight device 6 is installed on the control bracket 3. The counterweight device 6 includes a counterweight block 61 and two sets of sliding devices 62. Each sliding device 62 includes a connecting belt, a timing belt 621 and multiple sliding wheels 622. Gears mesh between each timing belt 621 and the sliding wheels 622. One end of each timing belt 621 is connected to the counterweight block 61, and the other end of each timing belt 621 is connected to the lifting movable plate 32.

[0040] The total weight of the counterweight 61 is equal to the total weight of all the devices on the lifting movable plate 32. Therefore, the lifting and lowering of the lifting movable plate 32 can be easily controlled by using the lifting control slide 31, making the control more convenient and accurate.

[0041] like Figures 5-8As shown, an eyeglass lens detection device 23 and four sets of eyeglass lens positioning devices 24 are installed on the eyeglass lens feeding conveyor belt 21. The specific number of sets can be adjusted to 6 or 8 sets, etc. The eyeglass lens detection device 23 is located at one end of the eyeglass lens feeding conveyor belt 21 and is used to detect information such as the diameter and thickness of the incoming eyeglass lens. Then, the eyeglass lens feeding conveyor belt 21 will convey the lens to the corresponding eyeglass lens positioning device 24. The eyeglass lens positioning device 24 is used to fix the eyeglass lens and lift it to a fixed position. After all four eyeglass lens positioning devices 24 are full of eyeglass lenses, the loading module bracket 4 is used to pick up the eyeglass lens and transfer it to the processing machine.

[0042] like Figure 6 As shown, the spectacle lens testing device 23 includes a spectacle lens diameter testing device 231 and a spectacle lens thickness testing device 232. The spectacle lens diameter testing device 231 includes a magnetically fixed base plate 2310, on which a magnetically fixed right plate 2311 and a magnetically fixed left plate 2312 are disposed. A magnetic scale 2313 is disposed on the magnetically fixed left plate 2312.

[0043] The diameter of the spectacle lens is measured by measuring the distance between the magnetically fixed right plate 2311 and the magnetically fixed left plate 2312 using a magnetic ruler 2313.

[0044] like Figure 7 As shown, the lens thickness detection device 232 includes a roller fixing device 2320 and a measuring drive cylinder 2321. A mold contact head 2322 is provided at the end of the measuring drive cylinder 2321, and a thickness detection sensor 2323 is synchronously provided on the mold contact head 2322.

[0045] The roller fixing device 2320 is equipped with four circular rollers arranged in a rectangle to clamp the lens. A measuring drive cylinder 2321 then pushes the mold contact head 2322 against the upper surface of the lens. Simultaneously, the thickness detection sensor 2323, synchronously mounted on the mold contact head 2322, moves the same distance. The thickness of the lens is calculated by comparing the distance traveled to the bottom (0 thickness). Finally, the diameter and thickness of the lens are sent to the control system, and the lens is then moved to the corresponding lens positioning device 24 via the lens feeding conveyor belt 21.

[0046] This utility model includes four eyeglass lens positioning devices, which can be configured as eyeglass lens positioning devices of the same diameter, or as eyeglass lens positioning devices of different sizes, depending on the requirements, for use on eyeglass lens processing devices of different sizes.

[0047] like Figure 8As shown, in this invention, the spectacle lens positioning device 24 includes a top block 241 and a cylinder 242 disposed below the top block 241. The top block 241 has a groove. If the size of the spectacle lens is larger than the groove, or if a spectacle lens is already placed in the groove, the newly delivered spectacle lens will continue to move along the spectacle lens feeding conveyor belt 211 to the rear spectacle lens positioning device 24. The cylinder 242 is used to lift the entire top block 241, causing the loading clamp 42 to pick up the spectacle lens.

[0048] like Figure 9-11 As shown, the feeding module bracket 4 of this utility model includes a feeding drive frame 41 and four sets of feeding clamps 42. Each feeding clamp 42 moves the spectacle lens on the spectacle lens positioning device 24 to the processing device. The feeding clamps 42 and the spectacle lens positioning device 24 are on the same vertical plane. The spectacle lens positioning device 24 moves up and down, while the feeding clamps 42 can move up and down and back and forth. The feeding clamps 42 place the picked-up spectacle lenses onto the four-station spectacle lens processing device. The four-station spectacle lens processing device can perform operations such as drilling and milling on four spectacle lenses at the same time.

[0049] Both ends of the loading drive frame 41 are provided with loading drive slides 411, and each loading drive slide 411 is provided with two loading clamps 42 at its end. The two loading drive slides 411 operate synchronously, causing the loading clamps 42 to move back and forth, and then the entire loading drive frame 41 is moved up and down by the lowering control slide 31.

[0050] The loading fixture 42 includes a loading rotary cylinder 421 and a loading gripper 422. The lifting control slide 31 and the loading drive slide 411 cooperate to control the loading gripper 422, so that the loading gripper 422 moves to the corresponding spectacle lens positioning device 24.

[0051] Since the size and shape of the eyeglass lenses will change after processing, eyeglass recycling fixtures are required. The recycling module bracket 5 includes a recycling drive frame 51 and multiple sets of recycling fixtures 52. Each recycling fixture 52 is used to move the eyeglass lenses processed by the processing device onto the eyeglass lens recycling conveyor belt 22. Both ends of the recycling drive frame 51 are provided with recycling drive slides 511, and each recycling drive slide 511 has two recycling fixtures 52 at its end.

[0052] Since the four-station lens processing device is located in front of the lens positioning device 24, the loading gripper 422 can directly move in a straight line to place the lens. However, due to size limitations, the recycling clamp 52 is located on the side of the loading gripper 422. Therefore, a turning device is needed to move the recycling clamp 52 to the front of the four-station lens processing device.

[0053] like Figure 11As shown, the recycling clamp 52 includes a recycling rotary cylinder 521 and a Z-shaped connecting rod 522. One end of the Z-shaped connecting rod 522 is connected to the recycling rotary cylinder 521, and the other end of the Z-shaped connecting rod 522 is connected to a recycling gripper 523. By rotating the Z-shaped connecting rod 522 180 degrees, the recycling gripper 523 can rotate to a position below the loading gripper 422, that is, in front of the four-station spectacle lens processing device.

[0054] This invention uses a lens detection device to automatically detect the thickness and diameter of eyeglass lenses. Based on the detected size, a lens positioning device automatically positions the lens on the lens feeding conveyor belt. A loading clamp automatically delivers the lens to a four-head automatic lens processing machine for processing. A recycling clamp automatically collects the processed lens from the four-head automatic lens processing machine and places it on a lens recycling conveyor belt. This fully automated movement and processing of eyeglass lenses improves production efficiency and product quality.

[0055] By installing a counterweight device, the entire lifting platform and counterweight are kept in a balanced state, reducing the vertical control pressure on the lifting control slide and making control easier and more accurate.

[0056] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
