[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0035] In order to solve the problem of low automation in the prior art equipment for detecting stray light on mobile phone lenses, the present invention provides a stray light detection device.

[0036] like Figures 1 to 11 As shown, the stray light detection equipment includes a conveying mechanism 10 and a detection mechanism 20 which are independently arranged. The conveying mechanism 10 includes an incoming material module 30, a discharging module 40 and a receiving module 50, wherein the incoming material module 30 includes an incoming material tray 31 and an incoming material support platform 32, the incoming material tray 31 is used to carry the lens, the incoming material tray 31 is fixed on the incoming material support platform 32, the discharging module 40 sends the lens in the incoming material tray 31 to the detection mechanism 20, so that the detection mechanism 20 performs stray light detection on the lens, and the discharging module 40 sends the lens detected by the detection mechanism 20 to the receiving module 50.

[0037] By setting up the independent transport mechanism 10 and the detection mechanism 20, the detection mechanism 20 can reduce the influence of the movement of the transport mechanism 10 on the detection mechanism 20 when detecting the lens, thereby increasing the detection accuracy of the detection mechanism 20. The arrangement of the discharge module 40 increases the automation of the stray light detection equipment, reduces the manual transport and arrangement of the lens, reduces the damage to the lens caused by manual operation, increases the appearance quality of the lens, and reduces the labor cost.

[0038] like Figure 5 As shown, the discharge module 40 includes a vacuum generator 41 and at least one discharge nozzle 42. The vacuum generator 41 provides suction force for the discharge nozzle 42. The discharge nozzle 42 has a buffer structure. The discharge nozzle 42 sucks the lens in the incoming tray 31 and sends it to the detection mechanism 20. The discharge module 40 is movable. The discharge nozzle 42 sucks the lens and sends it to the detection mechanism. The setting of the buffer structure can reduce the edge of the discharge nozzle 42 from colliding with the lens when the discharge nozzle 42 sucks the lens.

[0039] It should be noted that in the present application, the discharge module 40 has two discharge nozzles 42 arranged in parallel. When sucking the lens, the two discharge nozzles 42 work at the same time, which increases the working efficiency of the discharge module. Of course, the number of discharge nozzles 42 in the discharge module 40 can be greater than two, but when there are too many discharge nozzles 42, it is difficult to control the accuracy of suction and placement of the discharge nozzles 42. Of course, the working state of multiple discharge nozzles 42 can be set, with only one discharge nozzle 42 working or several discharge nozzles 42 working at the same time.

[0040] like Figure 4 and Figure 5 As shown, the transport mechanism 10 includes a visual system 60, and the discharge suction nozzle 42 sucks the lens and moves it to the visual system 60. After the visual system 60 compensates the position of the lens, the discharge suction nozzle 42 sends the lens to the detection mechanism 20. Since the position of the lens will deviate when the discharge suction nozzle 42 sucks the lens, the position of the lens is compensated by the visual system 60 so that the discharge suction nozzle 42 can accurately send the lens to the detection mechanism 20, thereby reducing the misalignment of the lens, increasing the accuracy of lens detection, and also reducing the risk of the lens being fragile and easy to fall after the lens is misaligned, and reducing the fragmentation rate of the lens.

[0041] like Figure 4 As shown, the incoming material module 30 also includes a plurality of first fixing blocks 33, and the incoming material tray 31 is fixed on the incoming material support platform 32 through the first fixing blocks 33. The first fixing blocks 33 are provided with first magnets, and the first fixing blocks 33 are adsorbed on the incoming material support platform 32 through the first magnets. The first fixing blocks 33 are L-shaped, and the first fixing blocks 33 are clamped at the corners of the incoming material tray 31. The magnetic attraction between the first fixing blocks 33 and the incoming material support platform 32 facilitates the removal of the first fixing blocks 33 and the installation of the incoming material tray 31, which is convenient for the installation of the incoming material tray 31, increases the convenience of the installation of the incoming material tray 31, and increases the tightness of the connection between the first fixing blocks 33 and the incoming material tray 31 and the incoming material support platform 32. Designing the first fixing blocks 33 to be L-shaped can prevent the shaking of the incoming material tray 31, and increase the stability of the incoming material tray 31 placed on the incoming material support platform 32. The corners of the incoming material tray 31 are adapted to the L-shaped first fixing block 33 , so that the first fixing block 33 and the two edges of the incoming material tray 31 are stopped, thereby increasing the working stability of the incoming material tray 31 .

[0042] It should be noted that in the present application, each incoming material tray 31 is fixed by a first fixing block 33, and the edge of the incoming material tray 31 that is not in contact with the first fixing block 33 can be stopped by other structural parts. For example, a stop edge or other structure can be added to stop the incoming material tray 31.

[0043] like Figure 4As shown, the material receiving module 50 includes a material receiving platform 52, a material receiving tray 51 and a second fixed block 53. The material receiving tray 51 is used to receive the lens after the inspection. The material receiving tray 51 is fixed on the material receiving platform 52 through the second fixed block 53. A second magnet is arranged in the second fixed block 53. The second fixed block 53 is adsorbed on the material receiving platform 52 through the second magnet. The second fixed block 53 is L-shaped and the second fixed block 53 is clamped at the corner of the material receiving tray 51. There are multiple material receiving holes for holding the lens in the material receiving tray 51, and each material receiving hole is arranged at equal intervals. After the lens is inspected by the inspection mechanism 20, the discharge nozzle 42 sucks the lens from the inspection mechanism 20 and sends it to the material receiving tray 51. The magnetic attraction between the second fixed block 53 and the receiving platform 52 makes it easy to remove the second fixed block 53 and install the receiving tray 51, which is convenient for installing the receiving tray 51, increases the convenience of installing the receiving tray 51, and increases the tightness of the connection between the second fixed block 53 and the receiving tray 51 and the receiving platform 52. Designing the second fixed block 53 in an L shape can prevent the shaking of the receiving tray 51, and increase the stability of the receiving tray 51 placed on the receiving platform 52. The corners of the receiving tray 51 are adapted to the L-shaped second fixed block 53, so that the second fixed block 53 and the two edges of the receiving tray 51 are stopped, which increases the working stability of the receiving tray 51.

[0044] It should be noted that there are a plurality of first sensors 34 on the incoming material support platform 32, and the plurality of first sensors 34 are arranged one-to-one with the incoming material tray 31, and the first sensors 34 are used to detect whether there is an incoming material tray 31 in the upper area thereof. There are a plurality of second sensors 54 on the receiving material support platform 52, and the plurality of second sensors 54 are arranged one-to-one with the receiving material tray 51, and the second sensors 54 are used to detect whether there is a receiving material tray 51 in the upper area thereof.

[0045] In the present application, there are multiple incoming material trays 31 and multiple receiving material trays 51 .

[0046] like Fig.10 As shown, the detection mechanism 20 includes a detection chip 70, a detection tray 80 and a detection tray transmission mechanism 90. The detection tray 80 has a plurality of detection holes for holding the lens. The detection tray 80 has a loading position, a detection position and a unloading position. The detection tray transmission mechanism 90 transmits the detection tray 80 between the loading position, the detection position and the unloading position. When the detection tray transmission mechanism 90 transports the detection tray 80 to the detection position, the detection chip 70 detects the lens.

[0047] When the detection tray 80 is located at the loading position, the discharge suction nozzle 42 of the discharge module 40 sucks the lens in the incoming tray 31 and moves it to the visual system 60 for coordinate capture. After completion, the lens is discharged into the detection tray 80 according to the position compensation. When the detection holes in the detection tray 80 are filled with lenses, the detection tray transmission mechanism 90 moves to the loading position to transport the detection tray 80 to the detection position, and the detection chip 70 detects the lens in the detection tray 80. After the detection is completed, the detection tray transmission mechanism 90 moves to the detection position to transport the detection tray 80 to the unloading position. The detection chip 70 feeds back the detection result of each lens to the control mechanism. The control mechanism controls the discharge suction nozzle 42 according to the detection structure to send the stray light lenses of different frequencies to the receiving tray 51 of the corresponding frequency.

[0048] It should be noted that in order to improve the detection efficiency, generally when the detection tray 80 is placed at the detection position for detection, the detection tray transmission mechanism 90 will drive another detection tray 80 to move to the loading position to load it, and when the detection tray 80 moves to the unloading position, another detection tray 80 moves to the detection position. This will greatly save time, reduce the idle period of the detection chip 70, and increase the utilization rate of the detection chip 70.

[0049] It should be noted that when the detection chip 70 is located at the detection position and the detection tray 80 is located at the detection position, the detection tray 80 is above the detection chip 70 .

[0050] In the present application, the incoming material support platform 32 is disposed adjacent to the receiving material support platform 52 , and both the incoming material support platform 32 and the receiving material support platform 52 are rectangular structures, and the long side of the incoming material support platform 32 is disposed adjacent to the short side of the receiving material support platform 52 .

[0051] like Fig.11 As shown, the detection mechanism 20 also includes an adjustment mechanism 100 for adjusting the position of the detection chip 70. The adjustment mechanism 100 includes a slide bar 101, a main body 102, and an electric slide 103. The main body 102 has a through hole, the slide bar 101 is slidably arranged at the through hole, the detection chip 70 is mounted on the main body 102, and the electric slide 103 is located below the main body 102. The electric slide 103 drives the main body 102 to slide along the slide bar 101 to adjust the position of the detection chip 70 in the Z-axis direction. By opening a through hole in the main body 102, the main body 102 can slide along the slide bar 101, thereby adjusting the position of the detection chip 70 in the Z-axis direction to adjust the distance between the detection chip 70 and the lens. It should be noted that the slide bar 101 is vertically placed on the base of the detection mechanism 20.

[0052] like Fig.11As shown, the first end of the main body 102 has an XY slide 104, and the XY slide 104 adjusts the position of the detection chip 70 in the X-axis direction and the Y-axis direction. The second end of the main body 102 has an inclined slide 105, and the inclined slide 105 is used to calibrate the level of the detection chip 70. A mounting plate 106 and a detection platform 108 are installed above the inclined slide 105. The detection chip 70 is mounted on the detection platform 108, and the detection platform 108 is fixed to the mounting plate 106 by a ball head adjustment screw 107 and a third magnet. By adjusting the inclination angle of the inclined slide 105, the level of the detection chip 70 is calibrated. The data detected when the detection chip 70 is placed horizontally is more reliable. The setting of the inclined slide 105 increases the accuracy of the detection of the detection chip 70. It should be noted that the XY slide 104 is a manual precision fine-tuning optical platform, which uses a micrometer head for manual fine-tuning. During the installation and debugging of the stray light detection equipment, the position of the XY slide 104 is adjusted to fix the XY position of the detection chip 70. There is no need to adjust the XY slide 104 during the subsequent stray light detection of the lens.

[0053] It should be noted that the X-axis, Y-axis, and Z-axis intersect at one point and are lines that are perpendicular to each other and extend in different directions.

[0054] like Figure 8 As shown, the detection mechanism 20 also includes an inner field of view structure 26, which includes a first guide rail 261, a sliding mechanism 263, a first motor 266 and an inner field of view light source board 267. The first guide rail 261 has a plurality of connecting feet 262 extending toward the detection mechanism 20, and each connecting foot 262 is respectively connected to the detection mechanism 20. The sliding mechanism 263 can slide along the first guide rail 261. The sliding mechanism 263 includes a dovetail groove slide 264 and a connecting plate 265 extending away from the conveying mechanism 10. The connecting plate 265 slides longitudinally along the dovetail groove slide 264. The first motor 266 is located below the first guide rail 261 and is electrically connected to the sliding mechanism 263. The first motor 266 provides power for the sliding mechanism 263. The inner field of view light source board 267 is connected to the side of the connecting plate 265 facing the base of the detection mechanism 20, and the inner field of view light source board 267 provides an inner field of view light source for the lens. The sliding mechanism 263 slides on the first guide rail 261 to change the horizontal position of the inner field light source board 267, and the dovetail groove slide 264 can change the height of the inner field light source board 267. This arrangement allows the device to automatically adjust the positional relationship between the inner field light source board 267 and the lens.

[0055] like Figure 4As shown, the transport mechanism 10 further includes two second guide rails 11 and a third guide rail 12, the two second guide rails 11 are located on the base of the transport mechanism 10, and the incoming module 30, the discharging module 40 and the receiving module 50 are all located on the base of the transport mechanism 10, the incoming module 30, the discharging module 40 and the receiving module 50 are located between the two second guide rails 11, and are located in the same plane as the two second guide rails 11. The third guide rail 12 can slide along the second guide rail 11, and the third guide rail 12 has a motion mechanism 13, and the motion mechanism 13 slides along the third guide rail 12 under the action of the driving force, and the discharging module 40 is installed on the motion mechanism 13, so that the discharging module 40 can be moved in two dimensions.

[0056] It should be noted that the two second guide rails 11 are not completely identical. In order to save space on the transport mechanism 10, the two second guide rails 11 are divided into a main guide rail and an auxiliary guide rail. The width of the main guide rail is greater than that of the auxiliary guide rail. The driving mechanism for driving the third guide rail 12 to move is arranged on one side of the main guide rail. In order to ensure that the first end of the third guide rail 12 and the second end of the third guide rail 12 are on the same horizontal line during movement, a pulley is generally provided at one end of the third guide rail 12 connected to the auxiliary guide rail, so that when the driving mechanism drives the second guide rail to move, each position of the first guide rail 261 is on the same horizontal plane.

[0057] In the present application, the second guide rail 11 and the third guide rail 12 are arranged vertically, so that the third guide rail 12 can slide on the second guide rail 11 easily.

[0058] like Figure 6As shown, the detection mechanism 20 includes an external field of view structure 21, which includes a frame 22, a plurality of universal pan-tilt platforms 23, a plurality of point light sources 24 and a second motor 25. The frame 22 has a top frame 221, a bottom frame 222 and a plurality of upright side edges 223. The first end of the side edge 223 is connected to the top frame 221, and the second end of the side edge 223 is connected to the bottom frame 222. The plurality of side edges 223 are arranged at intervals along the circumference of the bottom frame 222. The side edges 223 have sliding holes 224, and the sliding holes 224 extend along the height direction of the side edges 223. The plurality of universal pan-tilt platforms 23 are installed at the sliding holes 224 of the side edges 223. The point light sources 24 are fixed on the universal pan-tilt platforms 23, and the point light sources 24 are arranged one-to-one with the universal pan-tilt platforms 23. The point light sources 24 provide an external field of view light source for the lens. The second motor 25 is installed on the top frame 221, and the motor provides rotational power for the universal pan-tilt platform 23. The setting of the frame 22 allows the universal platform 23 and the point light source 24 to be installed in different directions and positions of the frame 22, so that multiple point light sources 24 form a three-dimensional light source together to illuminate the lens with a three-dimensional light source. Since different types of lenses have different requirements for three-dimensional light sources, the setting of the sliding hole 224 allows the height of the point light source 24 and the universal platform 23 to be adjusted to adapt to the requirements of different types of lenses for three-dimensional light sources. It should be noted that multiple point light sources 24 are respectively located on multiple side edges 223, and the point light sources 24 are arranged one-to-one with the side edges 223. Multiple universal platforms 23 are respectively located on multiple side edges 223, and the universal platforms 23 are arranged one-to-one with the side edges 223. In the present application, multiple point light sources 24 are located at the same height of the side edges 223, and multiple universal platforms 23 are also located at the same height of the side edges 223 to form a three-dimensional light source and reduce the differences between the point light sources.

[0059] When the detection chip 70 detects the lens, the inner field light source board 267 and the point light source 24 will illuminate the lens above the lens. The detection chip 70 will collect images of the lens respectively, and then analyze and process the collected images through a certain algorithm to determine whether the stray light is NG (No Good). Figure 7 In the embodiment, the lens is located between the point light source 24 and the detection chip 70, and the point light source 24 provides stereoscopic light for the lens so that the detection chip 70 can detect stray light. Fig. 9 The middle lens is located between the inner field light source board 267 and the detection chip 70. The inner field light source board 267 provides planar light for the lens so that the detection chip 70 can detect stray light.
