Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1, referring to Figure 1 and Figures 3 - 5 , a lens flaw detection device for glasses processing, including a concave base 1, a support base 2 welded to the outer wall of the rear side of the concave base 1, and a hollow detection table 3 welded to the outer wall of the middle of the top of the concave base 1;

[0036] In this embodiment, a light-transmitting plate 4 is fixedly embedded in the top of the hollow detection table 3, which is used to place the lens to be detected. A light source mechanism is provided inside the hollow detection table 3, which is used to emit light towards the light-transmitting plate 4;

[0037] Specifically, the light source mechanism includes a lamp holder 5 fixedly installed on the inner wall of the bottom of the hollow detection table 3, a lamp core 6 arranged in the lamp holder 5, a driving component, and two diffusion plates 8 rotatably installed on the top of the lamp holder 5 through two rotating members. The two diffusion plates 8 are symmetrically distributed.

[0038] Further, the driving component includes two worm wheels 7 fixedly sleeved on the two rotating members in sequence, a transmission shaft 9 rotatably installed in the hollow detection table 3, two worm shafts 10 fixedly sleeved on the transmission shaft 9 in sequence, and a first servo motor 11 fixedly connected to the front outer wall of the hollow detection table 3 through a motor base.

[0039] Furthermore, the output shaft of the first servo motor 11 is coaxially and fixedly connected to one end of the transmission shaft 9 through a coupling. The two worm shafts 10 are respectively meshed with the two worm wheels 7, and the spiral directions of the two worm shafts 10 are opposite.

[0040] When this embodiment is in use: First, the light source is emitted by the lamp core 6 in the lamp holder 5 and irradiates on the light-transmitting plate 4 to provide a bright field of view. And the use of a bottom light source may reduce the interference caused by the reflection on the lens surface to the visual imaging detection, which helps to improve the contrast and make the internal structure clearer. Second, the first servo motor 11 drives the two worm shafts 10 on the transmission shaft 9 to rotate. Subsequently, the two worm shafts 10 with opposite spiral directions drive the two worm wheels 7 meshed with them to rotate in the opposite direction. Further, the two worm wheels 7 will drive the two diffusion plates 8 on the two rotating members to rotate in the opposite direction, so as to facilitate the flexible adjustment of the diffusion angles of the two diffusion plates 8. Furthermore, it can increase the light source irradiation area and make the light emitted by the light source irradiate on the lens more evenly, improving the lighting effect. <{

[0041] Embodiment 2, referring to Figures 1 - 2 and Figures 6 - 7 This embodiment is optimized on the basis of Embodiment 1. Specifically, a lifting visual detection mechanism is provided on the top of the support base 2.

[0042] More specifically, the lifting visual detection mechanism includes a mounting frame 12 welded to the outer wall of the top of the support base 2, a lifting adjustment lead screw 13 rotatably installed in the mounting frame 12, a sensor bracket 14 threadedly connected to the lower part of the lifting adjustment lead screw 13, a second servo motor 18 fixedly connected to the outer wall of the top of the mounting frame 12 through a motor mounting plate, and a first visual sensor 15, a second visual sensor 16, and a third visual sensor 17 fixedly installed on the front outer wall of the sensor bracket 14 in sequence.

[0043] Further, two guiding vertical shafts 19 are symmetrically welded inside the mounting frame 12. Two guiding sleeves are fixedly embedded in the sensor bracket 14, and the two guiding sleeves are respectively slidably connected to the two guiding vertical shafts 19, which can ensure the stability of the linear motion of the sensor bracket 14.

[0044] Further, the output shaft of the second servo motor 18 is coaxially and fixedly connected to the top end of the lifting adjustment lead screw 13 through a coupling. A controller 34 is fixedly installed on the upper outer wall of the back surface of the mounting frame 12. The first vision sensor 15, the second vision sensor 16, and the third vision sensor 17 are all electrically connected to the controller 34;

[0045] In the specific use of this embodiment: The second servo motor 18 drives the lifting adjustment lead screw 13 to rotate. Subsequently, under the guidance of the two guiding vertical shafts 19, the sensor bracket 14 threadedly connected to the lifting adjustment lead screw 13 will move in the vertical direction. Thus, by simply driving the lifting adjustment lead screw 13 to rotate forward and backward by the second servo motor 18, the working heights of the various vision sensors on the sensor bracket 14 can be flexibly adjusted to achieve a better vision detection effect.

[0046] Example 3, referring to Figures 1 - 2 and Figure 5 This embodiment is an optimization based on Embodiment 1. Specifically: Two rotary feeders are symmetrically arranged on the top of the concave base 1 centered on the hollow inspection table 3. A movable loading and unloading assembly is provided on the upper front part of the support base 2;

[0047] More specifically, the movable loading and unloading assembly includes a third servo motor 20 fixedly installed on the upper outer wall of the front part of the support base 2, a transverse lead screw 21 coaxially and fixedly connected to the output shaft of the third servo motor 20 through a coupling, a sliding block 22 threadedly connected to the transverse lead screw 21, a connecting rod 23 welded to the front outer wall of the sliding block 22, and an electromagnetic vacuum chuck 24 connected to the connecting rod 23 through an electric push rod. When the electromagnetic vacuum chuck 24 and the electric push rod cooperate, the electric push rod can control the up and down movement of the electromagnetic vacuum chuck 24. The power-off and power-on of the electromagnetic vacuum chuck 24 can achieve the effects of sucking and discharging materials;

[0048] Further, a linear guide rail 25 is fixedly connected to the upper outer wall of the front part of the support base 2. The sliding block 22 is slidably connected to the linear guide rail 25. Two bearing seats are symmetrically fixed on the upper outer wall of the front part of the support base 2. The transverse lead screw 21 is rotatably installed on the two bearing seats;

[0049] More specifically, the rotary feeder includes a fixed box 26 fixedly connected to the top outer wall of the concave base 1, a stepping motor 27 fixedly installed on the top outer wall of the fixed box 26, a driving bevel gear 28 fixedly sleeved on the output shaft of the stepping motor 27, a rotating shaft 29 rotatably installed on the top of the fixed box 26, a driven bevel gear 30 fixedly sleeved on the bottom end of the rotating shaft 29, and a pin disk 31 coaxially welded to the top outer wall of the rotating shaft 29;

[0050] Further, the output shaft of the stepping motor 27 penetrates through one side of the fixed box 26, the driving bevel gear 28 meshes with the driven bevel gear 30, and both the electromagnetic vacuum chuck 24 and the stepping motor 27 are electrically connected to the controller 34;

[0051] Further, at the top of both pin turntables 31, a first lens storage tray 32 and a second lens storage tray 33 are sequentially fixed through a central pin. The first lens storage tray 32 is used to store the lenses to be detected, and the second lens storage tray 33 is used to store the lenses after the detection is completed. A plurality of annularly distributed lens placement grooves are formed on the surfaces of the first lens storage tray 32 and the second lens storage tray 33;

[0052] Further, the first vision sensor 15 is arranged above the first lens storage tray 32, the second vision sensor 16 is arranged above the light-transmitting plate 4, and the third vision sensor 17 is arranged above the second lens storage tray 33;

[0053] In the specific use of this embodiment: First, the third servo motor 20 drives the transverse lead screw 21 to rotate. Subsequently, under the guidance of the linear guide 25, the sliding block 22 threadedly connected to the transverse lead screw 21 will drive the electromagnetic vacuum chuck 24 on the connecting rod 23 to perform a linear motion;

[0054] Secondly, when the electromagnetic vacuum chuck 24 moves to the left end suction area, the lifting effect of the electric push rod enables the electromagnetic vacuum chuck 24 to suck up the lens to be detected placed on the first lens storage tray 32. Subsequently, the sliding block 22 moves the sucked-up lens to the hollow detection table 3 area. At this time, the electric push rod and the electromagnetic vacuum chuck 24 cooperate to place the lens on the light-transmitting plate 4 for surface defect detection to complete the flaw detection operation. After the feeding is completed, the sliding block 22 controls the electromagnetic vacuum chuck 24 to return to its original position. After the flaw detection operation is completed, the sliding block 22 controls the electromagnetic vacuum chuck 24 to move to the hollow detection table 3 area again to suck up the detected lens and send it to the second lens storage tray 33 area. At this time, the electric push rod and the electromagnetic vacuum chuck 24 cooperate to place the detected lens into the second lens storage tray 33. In this way, the automatic loading and unloading effect of the lens can be realized, the loading and unloading efficiency is improved, and it is beneficial to meet the requirements of large-scale lens flaw detection;

[0055] Finally, the first vision sensor 15 performs vision detection on the area of the first lens storage tray 32. When the lens at the material taking position of the first lens storage tray 32 is taken away, the controller 34 will control the left stepping motor 27 to work at this time. The stepping motor 27 will drive the driving bevel gear 28 to rotate. Subsequently, the driven bevel gear 30 engaged with the driving bevel gear 28 will drive the pin turntable 31 at the top of the rotating shaft 29 to automatically rotate a certain angle to rotate the lens at the next station to the material taking position. And the third vision sensor 17 performs vision detection on the area of the second lens storage tray 33. When a lens is placed at the material placing position of the second lens storage tray 33, the controller 34 will control the right stepping motor 27 to work at this time to make the pin turntable 31 automatically rotate a certain angle to rotate the next material receiving station to the material placing position;

[0056] In addition, after all the lenses on the first lens storage tray 32 are taken out, a replenishment operation can be performed. After all the lenses on the second lens storage tray 33 are filled, the entire second lens storage tray 33 can be removed for replacement operation.
