Description

Technical Field

[0001] This invention relates to the field of injection molding processing technology, and in particular to a VR lens cutting, marking and packaging integrated machine. Background Technology

[0002] In the injection molding process of plastic products, injection gates are generated. To ensure molding efficiency, multiple products are often molded at once on a single mold, with four cavities per mold. Manual cutting is inefficient and labor-intensive for workers. Product quality is greatly affected by individual skill levels. Traditional stamping and cutting methods can cause cracks in the relatively brittle plastic lens material. In addition, the cut edges are prone to producing lint and shavings, all of which affect the quality of the cut lenses. After cutting, the products need to be marked and packaged. Currently, lens cutting, marking, and packaging are semi-automated. Workers manually transport the products to the shearing machine for cutting, to the marking machine for marking, and then manually package them. This process is slow and can easily cause contamination or even damage to the lenses during the back-and-forth handling.

[0003] Chinese patent CN114178725A discloses a lens cutting and marking device that directly places the product on a special fixture on an XY motion platform. It lacks product identification capabilities. Lens products have mold cavity numbers during injection molding, and the marking varies depending on the product model. This patent design is suitable for laser cutting and marking stations with special fixtures for different workpiece (lens) models. However, when changing product types, the device itself cannot identify the model, requiring manual management and recording. The patent uses a laser cutting unit to cut the product. Firstly, laser cutting is relatively expensive. Secondly, due to the high power of laser cutting, the edges of the plastic are prone to yellowing, blackening, or scorching due to high temperatures during cutting. These phenomena severely affect the appearance of the finished lens. The patent does not disclose the packaging method or structure after marking.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a VR lens cutting, marking and packaging integrated machine. Summary of the Invention

Four lens mounting blocks 344 are installed on the blowing plate 343, corresponding to the placement positions of the lenses. The lens mounting blocks 344 have rectangular air outlets 340 that communicate with the interior of the blowing plate 343. After cutting, the lens is placed on the lens mounting block. On 344, the rectangular air nozzle is positioned vertically opposite to the sheared surface of the lens. Hot air is discharged from the hot air gun 341, passing through the reversing block 342, the air blowing plate 343, and the rectangular air nozzle 340. The hot air blows away the lint on the sheared surface of the lens and melts away the sheared wires. The reversing block 342 also has an air outlet on its side. A temperature sensor 345 is installed outside the air outlet to detect the temperature of the hot air. If the temperature is too low, the hot air gun 341 heats up and blows out hot air. If the temperature is too high, there is a risk of melting the sheared surface, so the hot air gun 341 reduces its workload.

[0043] refer to Figure 9 The four-axis loading robot 52 includes a loading four-axis robot 521, a camera module 522, a height sensor 523, and a lens gripper module 524. The loading four-axis robot 521 is equipped with a camera module 522 for identifying lens positions, a height sensor 523 for detecting the height of the umbrella frame placement, and a dual-station lens gripper module 524 for picking up and placing lenses. The double-layer umbrella frame transfer device 53 drives the umbrella frame to the placement position. The umbrella frame has several mounting slots on its front and back sides for storing lenses. (Reference) Figure 10 The lifting and rotating module 54 includes a lifting module 541 and a lifting frame 542 driven upward by the lifting module 541. Support blocks 5421 and V-shaped seats 5422 for supporting the umbrella frame are provided at both ends of the upper part of the lifting frame 542. A rotating module 543 is connected to both sides of the lifting frame 542. The rotating module 543 includes a push-pull cylinder 5431, a transfer frame 5432, and a positioning head 5432.

The rotary cylinder 5434 also has a flat clamping cylinder 5435 for clamping the umbrella frame installed on the rotary table.

[0044] In operation, the VR lens cutting, marking, and packaging integrated machine of this invention involves the operator loading materials. The tray 213 is manually placed onto the tooling plate 212. The tray 213 is positioned with the tooling plate 212 via positioning pins 214 and surrounding positioning blocks 215. A sensor detects the presence of the tray, and a power element 211 drives the tray 213 to the loading position. The tray scanning vision component 22 scans the QR code on the tray 213 to identify the product model. The gripper cylinder of the loading and transporting module 23 clamps the material rod. The mold cavity number on the lens is located on the back. The camera of the mold cavity number identification positioning module 24 takes a picture from bottom to top to identify the mold cavity number on the lens. After the mold cavity number is identified, the loading and transporting module 23 clamps the material rod and rotates it 180 degrees. The intermediate transfer module 25 clamps the short arm end of the product and places it onto the cutting and shifting module 26. The gripper cylinder 265 clamps the lens. The screw slide 261 moves the product between the upper die cutting module 27 and the lower die cutting module 28 to begin hot cutting. The lens and the material bar are separated. The four-axis robot handling module 31 simultaneously grips the material bar and the lens. Static electricity and dust on the sheared lens are removed at the anti-static station 32. The material bar is then placed in the material bar collection box 33. The lens is conveyed to the hot air blowing station 34. After shearing, the lens is placed on the lens mounting block 344. The rectangular air nozzle is positioned vertically opposite the sheared surface of the lens. Hot air is discharged from the hot air gun 341, passing through the reversing block 342, the air blowing plate 343, and the rectangular air blowing nozzle 340. The hot air blows away the burrs on the sheared surface of the lens and melts away the shearing filaments. The four-axis robot handling module 31 conveys the lens to the first lower camera detection component 42 to identify the lens position. Then, the lens is placed on the open marking carrier 413. The wind disk drives the marking carrier 413 to rotate to the marking machine 43. The marking machine 43 starts working and marks the lens. After marking, it moves to the barcode scanner 44 to scan the barcode and identify the marking information from the previous station. If the marking is defective, the four-axis loading robot 52 picks it up and moves it to the defective product tray 46. The four-axis loading robot 52 can identify the marking information. The four-axis loading robot 52 first picks up the lens and moves it to the identification position of the second lower camera component 45. Then it picks up the lens and moves it to the umbrella frame of the upper umbrella frame packaging device 5 or the finished product tray 51. The finished product tray 51 is used for buffering. The lens is installed on one side of the umbrella frame. The cover plate is placed manually and then pushed to the lifting and rotating module 54. The lifting and rotating module 54 lifts the umbrella frame and rotates it 180 degrees. Then it is placed on the double-layer umbrella frame transfer device 53 and fed again. The double-layer umbrella frame transfer device 53 feeds the double layers continuously without affecting the production rhythm.
