The feeding module 1 transports at least one optical lens 5 to the transfer module 2. The transfer module 2 transfers the at least one optical lens 5 to the microscopic detection module 3 for good product detection, and then transports it to the unloading module 4. The unloading module 4 tray arranges the optical lenses 5 that pass the detection and the optical lenses 5 that fail the detection, respectively. The feeding module 1, the transfer module 2, the microscopic detection module 3, and the unloading module 4 are all fixedly connected to a base 8. This embodiment integrates the feeding and unloading tray arrangement of the optical lenses 5 and the microscopic detection together, automatically performs microscopic detection after feeding, and screens out defective lenses, thereby improving the detection efficiency and the tray arrangement efficiency. Integrating the feeding, microscopic detection, and unloading tray arrangement in one equipment greatly shortens the time for the lenses from feeding to unloading tray arrangement, and further shortens the time for the lenses to be transported in the equipment, reduces the risk of pollution or loss of the lenses during the transportation process, and improves the yield.

[0046] As an alternative implementation, as shown in Figure 2 and 4As shown, the feeding module 1 comprises a demolding feeding mechanism 11, a ejector pin demolding mechanism 12 and a feeding and taking mechanism 13; the demolding feeding mechanism 11 adjusts the position to align the optical lens 5 with the ejector pin demolding mechanism 12 for demolding, the feeding and taking mechanism 13 sucks the optical lens 5 and rotates by a certain angle to the transfer module 2. Preferably, the demolding feeding mechanism 11 comprises a support disc 111, a four-axis adjusting mechanism 15 which has been fixedly connected with the support disc 111, and the support disc 111 is a hollow disc; the demolding feeding mechanism 11 moves in X, Y, Z, R four degrees of freedom directions through the four-axis adjusting mechanism 15, for adjusting the position of the optical lens 5 to align with the ejector pin demolding mechanism 12; the four-axis adjusting mechanism 15 comprises a third movement assembly 151, a fourth movement assembly 153, a fifth movement assembly 155 and a sixth movement assembly 157; preferably, the third movement assembly 151, the fourth movement assembly 153, the sixth movement assembly 157 and the support disc 111 are fixedly connected in sequence, and the fifth movement assembly 155 is fixedly connected with the support disc 111; the third movement assembly 151 is driven by a third motor 152 to move in the X-axis direction, and through the transmission principle of force, the sliding force generated by the third movement assembly 151 can be transmitted to the support disc 111, so as to drive the support disc 111 to move in the X-axis direction; the fourth movement assembly 153 is driven by a fourth motor 154 to move in the Y-axis direction, and the same as the third movement assembly 151, the fourth movement assembly 153 can drive the support disc 111 to move in the Y-axis direction; the fifth movement assembly 155 drives a first pulley 1552 to rotate through a fifth motor 156, so that the first pulley 1552 drives the support disc 111 to rotate through a first belt 1551, and then the support disc 111 rotates in the Z-axis direction (the rotation in the Z-axis direction is the movement in the R degree of freedom); the sixth movement assembly 157 drives a second pulley 1572 to rotate through a sixth motor 158, so that the second pulley 1572 drives the screw structure 159 to move up and down through a second belt 1571, and then drives the support disc 111 fixedly connected with the screw structure 159 to move in the Z-axis direction. By adjusting the optical lens 5 on the support disc 111 through the four-axis adjusting mechanism 15, the optical lens 5, the ejector pin demolding mechanism 12 and the feeding manipulator 133 are more easily aligned, and by rotating the support disc 111 through the sixth movement assembly 157, the position of the optical lens 5 is adjusted, so that the taking suction nozzle 7 on the feeding manipulator 133 can just adsorb the lens surface of the optical lens 5.

[0047] As Figure 3 and Figure 5As shown, the ejector pin demolding mechanism 12 is arranged inside the support wheel disc 111; the ejector pin demolding mechanism 12 comprises an ejector pin 121, an ejector pin barrel 122 and an ejector pin adjusting mechanism 16; the ejector pin 121 is arranged inside the ejector pin barrel 122, when demolding is needed, the ejector pin barrel 122 will eject the ejector pin 121; a reset spring 168 fixedly connected with the ejector pin 121 is arranged below the ejector pin barrel 122, driven by a ninth motor 169, the ejector pin 121 is ejected from the ejector pin barrel 122 upwards, and the reset spring 168 can reset the ejector pin 121 back to the inside of the ejector pin barrel 122; the ejector pin demolding mechanism 12 can move in three degrees of freedom directions of X, Y and Z axes through the ejector pin adjusting mechanism 16; the ejector pin adjusting mechanism 16 comprises a seventh motion assembly 161, an eighth motion assembly 163 and a ninth motion assembly 165, preferably the eighth motion assembly 163, the seventh motion assembly 161 and the ninth motion assembly 165 are fixedly connected in sequence, the ejector pin barrel 122 is fixedly connected on the ninth motion assembly 165, and the sequence can be adaptively adjusted according to actual needs; the seventh motion assembly 161 is driven by a seventh motor 162 to move in the X axis direction, through the force transmission principle, the sliding force generated by the seventh motion assembly 161 can be transmitted to the ejector pin barrel 122, so as to drive the ejector pin barrel 122 to move in the X axis direction; the eighth motion assembly 163 is driven by an eighth motor 164 to move in the Y axis direction, and the same, the eighth motion assembly 163 can drive the ejector pin barrel 122 to move in the Y axis direction; the ninth motion assembly 165 is driven by the ninth motor 169, specifically, an ejector pin pneumatic cylinder 166 drives the trapezoidal slide block 167 of the ninth motion assembly 165 to move in the Y axis direction, so that the trapezoidal slide block 167 pushes the direction-changing wheel 1671 to roll upwards, and then drives the ninth motion assembly 165 to move in the Z axis direction, through the force transmission principle, the sliding force generated by the ninth motion assembly 165 can be transmitted to the ejector pin barrel 122, so as to drive the ejector pin barrel 122 to move in the Z axis direction.

[0048] As shown in the drawings, Figure 6 As shown, the feeding and taking mechanism 13 is provided with a plurality of stations around, and each station is provided with a feeding manipulator 133; the feeding motor 132 can drive the feeding turntable 131 to rotate, so that the feeding manipulators 133 on the plurality of stations can be rotated to the corresponding positions to take or place materials. Workers fix and place the blue film disc carrying the optical lenses 5 needing demolding above the support wheel disc 111; when the ejector pin barrel 122 is aligned with the optical lenses 5, 1-2 ejector pins 121 in the central position of the optical lenses 5 are ejected to pierce the blue film, so that the optical lenses 5 on the blue film are demolded, at the same time, the feeding manipulator 133 of the feeding and taking mechanism 13 cooperates with the suction lens, the support wheel disc 111 rotates by a certain angle to transport the lens to the first receiving mechanism 21. The ejector pin demolding cooperates with the feeding manipulator 133 to take materials, and the accurate time and position cooperation can ensure the demolding and feeding effect. When the optical lenses 5 on one blue film disc are all fed, the equipment will issue an alarm to remind the workers to feed.

[0049] As an alternative embodiment, as shown in Figures 7-8 The transfer module 2 includes a first receiving mechanism 21, a second receiving mechanism 22 and a transfer taking mechanism 23. The loading taking mechanism 13 places the at least one optical lens 5 on the first receiving mechanism 21. The transfer taking mechanism 23 horizontally clamps both sides of the at least one optical lens 5, rotates by a certain angle to the microscopic detection module 3 for good product detection, and after detection, rotates by a certain angle to place the optical lens 5 on the second receiving mechanism 22. The receiving tables 24 of the first receiving mechanism 21 and the second receiving mechanism 22 are both a plurality of support blocks arranged at intervals. In this way, when the optical lens 5 is placed on the receiving table 24, the contact area between the optical lens 5 and the receiving table 24 can be reduced, thereby reducing the risk of contamination and wear. The transfer taking mechanism 23 includes a transfer turntable 231 and a clamping jaw 233 arranged around the transfer turntable 231. Preferably, as shown in Figures 9-10 two clamping jaws 233 are arranged side by side in one station, which can clamp two optical lenses 5 at a time, thereby improving the transportation efficiency. The number of clamping jaws 233 in one station can be set to one or more according to actual needs. A clamping jaw motor 235 drives the movement of a clamping jaw adjusting assembly 234, thereby driving the clamping jaw 233 to clamp or release the lens. A buffer spring 236 is arranged between the clamping jaw 233 and the clamping jaw adjusting assembly 234, so that the clamping jaw 233 has a certain buffer when clamping the lens, thereby avoiding the lens from being broken or damaged. One side below the clamping jaw 233 is provided with a row of cleaning columns 25, the number of which is equal to the interval number of the receiving table 24. When a lens accidentally falls into the interval of the receiving table 24, the cleaning column 25 can pass through the interval of the receiving table 24 with the rotation of the transfer turntable 231, thereby pushing out the lens in the interval.
