[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] This utility model relates to a mobile phone camera lens testing device, such as... Figures 1-2 As shown, the system includes a frame 1, and a film peeling and feeding mechanism 2, a vision picking mechanism 3, an inspection mechanism 4, a receiving and coating mechanism 5, and a directional picking mechanism 6, all mounted on the frame 1. The film peeling and feeding mechanism 2 is used to convey products and peel off the film covering the product surface. The vision picking mechanism 3 is located at the discharge end of the film peeling and feeding mechanism 2 and is used to move the products peeled off by the film peeling and feeding mechanism 2 to the inspection mechanism 4 for inspection. The receiving and coating mechanism 5 is located at the discharge end of the inspection mechanism 4 and is used to coat the inspected products and output them. The directional picking mechanism 6 is located between the inspection mechanism 4 and the receiving and coating mechanism 5 to move the inspected products into the receiving and coating mechanism 5.

[0036] Taking the inspection of mobile phone camera lenses as an example, the lenses are arranged at intervals and connected together by strip-shaped film materials adhering to their upper and lower surfaces to form a long strip of material. After the strip-shaped film material is peeled off by the upper and lower peeling components driven by the peeling drive 25 in the peeling and feeding mechanism 2, the lens is conveyed to the picking rack 32 of the vision picking mechanism 3. The vision picking mechanism 3, through the vision positioning camera 36, ​​and in conjunction with the operation of the linear module 2 33 and the single-action vacuum picking cylinder 34, conveys the lens to the placement stage 41 of the inspection mechanism 4. The rotating platform 41 then drives the lenses to be sequentially transferred to the inspection areas of the window inspection unit 43 and the ink inspection unit 44 for appearance and ink inspection. After inspection, the lenses are driven by the linear module 3 61 of the directional material handling mechanism 6 to operate the single-action vacuum material handling cylinder 2 62, which transfers the inspected lenses to the receiving and coating mechanism 5. Finally, the coating drive 56 drives the film pulling mechanism to pull out the film material on the upper film feeding tension air shaft 51 and the lower film feeding tension air shaft 52, which are respectively fitted with film material, and then adhere them to the upper and lower surfaces of the lens, so that the product can be output.

[0037] Specifically, such as Figures 3-4 As shown, the upper film peeling assembly includes an upper film peeling shaft 21 for peeling off the upper film material and an upper film tension air expansion shaft 23 for winding up the upper film material. The lower film peeling assembly includes a lower film peeling blade 22 for peeling off the lower film material, a lower film tension air expansion shaft 24 for winding up the lower film material, and an active film winding shaft 26 and a driven film winding shaft 27 arranged in parallel for pulling up the film material. One end of the active film winding shaft 26 and the driven film winding shaft 27 are meshed by gears so that when the active film winding shaft 26 rotates, the driven film winding shaft 27 rotates synchronously in opposite directions to form a radial resultant force to pull up the film material. The active take-up shaft 26 is connected to a multi-grooved synchronous pulley away from its meshing end. The multi-grooved synchronous pulley is connected to the upper take-up tension air shaft 23, the lower take-up tension air shaft 24, and the synchronous pulley connected to the end of the peeling drive 25 via synchronous belts. This allows the upper take-up tension air shaft 23 and the lower take-up tension air shaft 24 to rotate and rewind the film material when the peeling drive 25 drives the active take-up shaft 26 to rotate. In use, after the material passes between the lower film peeling knife 22 and the upper film peeling shaft 21, the upper and lower film materials form wrap angles with the upper film peeling shaft 21 and the lower film peeling knife 22, respectively. The free ends of the material are then wound onto the upper take-up tension air shaft 23 and the lower take-up tension air shaft 24. At this time, the lens is dislodged onto the take-up rack 32 due to the peeling of the film material.

[0038] like Figure 5As shown, the vision-based material handling mechanism 3 also includes an "L"-shaped support frame 35. A vision positioning camera 36 is mounted at the top of the support frame 35 and illuminates the lens located on the material handling rack 32. A single-action vacuum material handling cylinder 34 is mounted on the movable end of the linear module 33, which is horizontally mounted on the support frame 35 and located below the vision positioning camera 36. In use, after the vision positioning camera 36 illuminates the lens on the material handling rack 32, it transmits a signal to the control unit of the entire device. The control unit then activates the linear module 33 to move the single-action vacuum material handling cylinder 34 above the lens. The lens is then adsorbed by the operation of the single-action vacuum material handling cylinder 34 and moved to the detection mechanism 4.

[0039] Furthermore, in order to facilitate the adjustment of the position of the pick-up rack 32 at the discharge end of the film peeling and feeding mechanism 2 so that the lens can be better placed on the pick-up rack 32, a linear module 31 is installed between the pick-up rack 32 and the frame 1. The operation of the linear module 31 drives the pick-up rack 32 to move, thereby adjusting the position of the pick-up rack 32.

[0040] like Figures 6-7As shown, the stage 41 includes a multi-station turntable 411 and a stage drive 42 for driving the multi-station turntable 411 to rotate; a plurality of positioning holes 412 are equally spaced along the periphery of the multi-station turntable 411, and a transparent fixture 413 for positioning products is detachably connected inside the positioning holes 412; the stage drive 42 includes a stepper motor 421 and a reducer 422 installed at the output end of the stepper motor 421, the output end of the reducer 422 is connected to the multi-station turntable 411 to drive the multi-station turntable 411 to rotate along its axis; the window inspection unit 43 includes an industrial camera 433 located above the stage 41 and a parallel coaxial light source 434 connected to the illumination end of the industrial camera 433, the industrial camera 433 and the parallel coaxial light source 434 are connected to each other. The first coaxial light source 434 is mounted on the window inspection frame 431. A high-precision fine-tuning slider 432 can be set between the first industrial camera 433 and the first coaxial light source 434 and the window inspection frame 431 to facilitate the adjustment of their distance. The ink inspection unit 44 includes a second industrial camera 443 located above the stage 41, a telecentric lens 444 connected to the illumination end of the second industrial camera 443, and a second coaxial light source 445 located at the bottom of the telecentric lens 444. The second industrial camera 443 and the second coaxial light source 445 are both mounted on the ink inspection frame 441. A high-precision fine-tuning slider 442 can be set between the second industrial camera 443 and the second coaxial light source 445 and the ink inspection frame 441 to facilitate the adjustment of their distance. As an example, in this embodiment, three sets of window inspection units 43 are equally spaced to facilitate simultaneous inspection of multiple lenses and improve inspection efficiency. The ink inspection units 44 are located at the end of the window inspection units 43, and their spacing is the same as the spacing between the window inspection units 43, so that the multi-station turntable 411 can drive the lenses to be placed sequentially in the inspection areas of the two units.

[0041] In operation, the lens, after being picked up by the single-action vacuum pick-up cylinder 34, is placed inside the transparent fixture 413. As the multi-station turntable 411 rotates, the lens is moved to the inspection area of ​​the window inspection unit 43. Surface defects of the lens are inspected using the industrial camera 433 and the parallel coaxial light source 434. After surface inspection, the multi-station turntable 411 rotates again, moving the lens to the inspection area of ​​the ink inspection unit 44. The ink printed on the lens is inspected using the industrial camera 443, the telecentric lens 444, and the parallel coaxial light source 445. Note that to improve inspection accuracy, a backlight 46 is installed below the inspection areas of the window inspection unit 43 and the ink inspection unit 44. The backlight 46 illuminates the lens from the bottom of the transparent fixture 413, creating a contrast between light and dark at the lens defects due to differences in light transmittance, making them easier to identify.

[0042] like Figures 8-9As shown, the receiving and coating mechanism 5 also includes a material placement plate 55 disposed at the input end of the film pulling mechanism for placing products. The film pulling mechanism includes a driving coating shaft 53 and a driven coating shaft 54 ​​arranged in parallel and rotating synchronously in opposite directions to pull out the coated products. The driving coating shaft 53 and the driven coating shaft 54 ​​of the film pulling mechanism are connected in the same way as the driving film receiving shaft 26 and the driven film receiving shaft 27 in the film peeling and feeding mechanism 2. The belt connection between the upper film feeding tension air shaft 51, the lower film feeding tension air shaft 52, the driving coating shaft 53, and the coating drive component 56 is also the same as that of the film peeling and feeding mechanism 2, and will not be described again here.

[0043] In use, the film material on the lower film feeding tension air expansion shaft 52 adheres to the surface of the placement plate 55 and is pulled by the combined force of the active coating shaft 53 and the driven coating shaft 54. Meanwhile, the film material on the upper film feeding tension air expansion shaft 51 is located above the film material adhering to the surface of the placement plate 55 and is opposite to it, and is also pulled by the combined force. There is a space for the directional material picking mechanism 6 to move above the placement plate 55. The single-action vacuum picking cylinder 62 of the directional material picking mechanism 6, through the movement of the linear module 61, adsorbs the lens and places it on the surface of the placement plate 55 to adhere to the lower film material. Then, the upper and lower film materials are pulled by the combined force of the active coating shaft 53 and the driven coating shaft 54. Thus, when passing between the active coating shaft 53 and the driven coating shaft 54, the upper and lower film materials are adhered together to cover the lens and then transport it out.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
