[0039] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0040] See Figures 1-3 As shown, this application provides an optical lens inspection device 100, which includes a machine base 110, a material handling mechanism 120, at least one inspection pattern 130, and a flipping mechanism 140. The optical lens inspection device 100 is used to inspect the imaging quality of optical lenses. The machine base 110 has a loading / unloading area 111 and an inspection area 112. The loading / unloading area 111 is used for loading and unloading optical lenses to be inspected, and the inspection area 112 is used for imaging inspection of the optical lenses to be inspected.

[0041] The taking mechanism 120 is arranged on the machine table 110, and the taking mechanism 120 can move between the loading and unloading area 111 and the detection area 112, and the taking mechanism 120 is used to drive the optical lens to move between the loading and unloading area 111 and the detection area 112. For example, after the optical lens to be detected is loaded on the loading and unloading area 111, the taking mechanism 120 moves to the loading and unloading area 111 to pick up the optical lens by grabbing, sucking or the like. After the taking mechanism 120 picks up the optical lens, the taking mechanism 120 moves from the loading and unloading area 111 to the detection area 112 to feed the optical lens to the detection area 112 for imaging quality detection. After the detection of the optical lens is completed, the taking mechanism 120 moves to the detection area 112 to pick up the optical lens again and moves to the loading and unloading area 111 to unload the optical lens.

[0042] The detection pattern piece 130 is arranged on the detection area 112, and when the optical lens moves to the detection area 112, the detection pattern piece 130 can be imaged on the optical lens. For example, when the optical lens moves to the detection area 112 and the optical lens is above the detection pattern piece 130, the optical lens can take a picture of the detection pattern piece 130. By analyzing the imaging quality of the detection pattern piece 130 by the optical lens, the imaging quality of the optical lens can be determined.

[0043] The turnover mechanism 140 is arranged on the machine table 110, and the turnover mechanism 140 is used to turn over the optical lens located on the loading and unloading area 111. Since the optical lens to be detected loaded on the loading and unloading area 111 can have a reverse defect, the optical lens can be automatically turned over by the turnover mechanism 140 to ensure that the optical lens fed to the detection area 112 can image the detection pattern piece 130 in a preset direction, thereby improving the detection efficiency and reliability of the detection result of the optical lens.

[0044] The above optical lens detection device 100 can feed the optical lens loaded on the loading and unloading area 111 to the detection area 112 by the taking mechanism 120, the detection pattern piece 130 is imaged on the optical lens to detect the imaging quality of the optical lens, and after the detection of the optical lens is completed, the taking mechanism 120 can feed the detected optical lens from the detection area 112 to the loading and unloading area 111 for unloading operation, thereby automatically detecting the imaging quality of the optical lens.

[0045] In an embodiment, referring to Figures 1-3As shown, the optical lens detection device 100 further comprises a camera module 150, which is configured to acquire the front direction and the reverse direction of the optical lens fed to the feeding and discharging area 111. The turnover mechanism 140 comprises a first driving source 141 and a turnover member 142, the turnover member 142 is in transmission connection with the first driving source 141, and the first driving source 141 can drive the rotation of the turnover member 142. For example, the first driving source 141 can be a rotary motor, a rotary cylinder or other driving elements. When the optical lens in the feeding and discharging area 111 is in the reverse direction, the taking mechanism 120 can move to the turnover member 142 and feed the optical lens to the turnover member 142. For example, the turnover member 142 can fix the optical lens by suction, grabbing or other methods. For example, when the camera module 150 acquires the reverse direction of the optical lens in the feeding and discharging area 111, the camera module 150 feeds back the information of the reverse direction of the optical lens to the control module, the taking mechanism 120 moves to the turnover member 142 and feeds the optical lens to the turnover member 142, and the first driving source 141 drives the rotation of the turnover member 142 to automatically turn over the optical lens, so as to ensure that the optical lens fed to the detection area 112 can image the detection pattern member 130 according to the preset direction.

[0046] In this embodiment, the camera module 150 comprises a first camera module 151, a second camera module 152 and a third camera module 153. The first camera module 151 is arranged on the taking mechanism 120, and the first camera module 151 can detect the front direction and the reverse direction of the optical lens fed to the feeding and discharging area 111. When the first camera module 151 detects that the optical lens fed to the feeding and discharging area 111 is in the front direction, the taking mechanism 120 can directly feed the optical lens to the detection area 112 for imaging quality detection. Conversely, when the first camera module 151 detects that the optical lens fed to the feeding and discharging area 111 is in the reverse direction, the taking mechanism 120 moves to the turnover member 142 and feeds the optical lens to the turnover member 142 to automatically turn over the optical lens, and then feeds the optical lens to the detection area 112 for imaging quality detection after the optical lens is turned over. The second camera module 152 can detect whether the optical lens exists in the feeding and discharging area 111. When the second camera module 152 detects that the optical lens exists in the feeding and discharging area 111, the taking mechanism 120 performs feeding detection or discharging operation on the optical lens. Conversely, when the second camera module 152 detects that the optical lens does not exist in the feeding and discharging area 111, the taking mechanism 120 performs feeding operation on the optical lens.

[0047] In one embodiment, referring to Figures 1-3As shown, the detection pattern pieces 130 are multiple, and the multiple detection pattern pieces 130 are arranged at intervals in the detection area 112. For example, as the detection pattern pieces 130 are three, the three detection pattern pieces 130 are defined as a first detection pattern piece 131, a second detection pattern piece 132, and a third detection pattern piece 133, respectively. The first detection pattern piece 131, the second detection pattern piece 132, and the third detection pattern piece 133 are arranged in the horizontal direction at intervals. Figure 2 When the optical lens moves to the detection area 112, the optical lens can move to a position capable of shooting any detection pattern piece 130. For example, when the optical lens moves to the detection area 112 and is located above the first detection pattern piece 131, the first detection pattern piece 131 is imaged on the optical lens. For another example, when the optical lens moves to the detection area 112 and is located above the second detection pattern piece 132, the second detection pattern piece 132 is imaged on the optical lens. For another example, when the optical lens moves to the detection area 112 and is located above the third detection pattern piece 133, the third detection pattern piece 133 is imaged on the optical lens.

[0048] In this way, by shooting the multiple detection pattern pieces 130 through the optical lens, the imaging quality of the optical lens can be detected multiple times to improve the reliability of the detection result of the optical lens. It should be noted that the number of the detection pattern pieces 130 is not limited to three as provided in the above embodiment, and the number of the detection pattern pieces 130 can also be four, five, or other. The specific number of the detection pattern pieces 130 is not limited in the present application.

[0049] In an embodiment, referring to Figures 1-4 As shown, the machine table 110 includes a detection frame 113, and the detection frame 113 has the detection area 112. The optical lens detection device 100 further includes an imaging module 160 movably arranged on the detection frame 113, and the imaging module 160 is used for shooting the imaging picture of the optical lens. Since the optical lens can only image the detection pattern pieces 130 but does not have image analysis function, the imaging picture of the optical lens is shot by the imaging module 160 and visualized on the user terminal to analyze the imaging quality of the optical lens, and then the imaging quality of the optical lens is detected.

[0050] Further, continuing to refer to Figure 5 and Figure 6As shown, the optical lens detection device 100 further comprises a carrier 161, a first alignment module 162 and a second alignment module 163. The carrier 161 is arranged on the first alignment module 162, and the carrier 161 is used to accommodate the optical lens. For example, the carrier 161 has a bearing cavity for bearing the optical lens, so as to accommodate the optical lens. For another example, the carrier 161 has a suction part, and the carrier 161 can accommodate the optical lens by negative pressure suction. The first alignment module 162 is movably arranged on the detection frame 113. For example, the detection frame 113 is provided with a transfer module 114, the first alignment module 162 is in transmission connection with the transfer module 114, and the first alignment module 162 is located above the carrier 161. The first alignment module 162 can take the carrier 161 by suction, grabbing, clamping or the like. The transfer module 114 can drive the first alignment module 162 to move the optical lens between the plurality of detection pattern pieces 130, so that the optical lens can move and image the plurality of detection pattern pieces 130. The second alignment module 163 is used to accommodate the imaging module 160, and the second alignment module 163 is movably arranged on the detection frame 113. For example, the second alignment module 163 is in transmission connection with the transfer module 114, and the second alignment module 162 is located above the carrier 161. The transfer module 114 can drive the second alignment module 163 to move relative to the detection frame 113, so that the imaging module 160 can move with the optical lens. During the movement and imaging of the plurality of detection pattern pieces 130 by the optical lens, the imaging module 160 can always shoot the imaging picture of the optical lens.

[0051] The first alignment module 162 can adjust the carrier 161 in multiple axes, and the second alignment module 163 can adjust the imaging module 160 in multiple axes. Since the carrier 161 is used to accommodate the optical lens, the cooperation of the first alignment module 162 and the second alignment module 163 can adjust the alignment of the optical lens and the imaging module 160, so that the imaging module 160 can shoot the imaging picture of the optical lens. For example, the first alignment module 162 comprises a first adjustment module 1621, and the carrier 161 is in transmission connection with the first adjustment module 1621. The first adjustment module 1621 can move or rotate the carrier 161 in the X-axis direction, the Y-axis direction and the Z-axis direction, so as to adjust the position and direction of the carrier 161. Figure 1 Similarly, the second alignment module 163 comprises a second adjustment module 1631, and the imaging module 160 is in transmission connection with the second adjustment module 1631. The second adjustment module 1631 can move or rotate the imaging module 160 in the X-axis direction, the Y-axis direction and the Z-axis direction, so as to adjust the position and direction of the imaging module 160. Figure 1

[0052] Since the position and angle relationship between the detection pattern piece 130 and the optical lens will affect the imaging quality of the optical lens, in an embodiment, the detection pattern piece 130 is provided with a plurality of detection patterns 131, and the detection pattern 131 is used to detect the imaging quality of the optical lens. For example, the detection pattern 131 is a circle, and the detection pattern 131 is used to detect the circle of confusion of the optical lens. For another example, the detection pattern 131 is a square, and the detection pattern 131 is used to detect the squareness of the optical lens. For another example, the detection pattern 131 is a line, and the detection pattern 131 is used to detect the line of the optical lens. For another example, the detection pattern 131 is a cross, and the detection pattern 131 is used to detect the cross of the optical lens. Figure 1 ,​Figure 2 、 Figure 4 With Figure 7 As shown in , the detection pattern piece 130 includes a bracket 134, a carrier 135, a second driving source 136, and a detection pattern 137. The bracket 134 is arranged on the machine table 110 to achieve the mounting and fixation of the detection pattern piece 130. The carrier 135 is movably arranged on the bracket 134, and the carrier 135 is in transmission connection with the second driving source 136. The second driving source 136 can be a driving element such as an electric cylinder or a hydraulic cylinder. The detection pattern 137 is arranged on the carrier 135 and can be imaged on the optical lens. The position and angle relationship between the carrier 135 and the machine table 110 can be adjusted by the second driving source 136, so as to adjust the position and angle relationship between the detection pattern 137 and the optical lens. For example, the detection pattern 137 is adjusted to be perpendicular to the imaging direction of the optical lens, so as to avoid the influence of the position and angle deviation of the detection pattern 137 on the imaging quality of the optical lens, and improve the imaging quality detection result reliability of the optical lens.

[0053] In an embodiment, as shown in Figures 1-3 , the material taking mechanism 120 includes a linear driving module 121 and a material taking arm 122. The material taking arm 122 is used for taking the optical lens. The linear driving module 121 is arranged on the machine table 110 by welding, screwing or the like. The material taking arm 122 is in transmission connection with the linear driving module 121. The linear driving module 121 is used for driving the material taking arm 122 to move along the X-axis direction, the Y-axis direction and the Z-axis direction of Figure 1 , that is to say, the linear driving module 121 can drive the movement of the material taking arm 122 in the three-dimensional space, so as to perform the taking and feeding operation of the material taking arm 122 on the optical lens.

[0054] Further, since the outer peripheral contour of the optical lens may be different when the forward optical lens and the reverse optical lens are fed to the feeding and discharging area 111, the material taking mechanism 120 may have the phenomenon that the clamp and the optical lens are not matched, resulting in failure of clamping. Based on this, in an embodiment, as shown in Figures 1-3As shown, the optical lens detection device 100 further comprises a clamp seat 170, the clamp seat 170 is arranged on the machine table 110, and the clamp seat 170 stores a plurality of different specifications of clamps, and the taking arm 122 can move to the clamp seat 170 and take and place the clamps to adapt to the grabbing of the forward optical lens or the reverse optical lens. For example, the clamp adapted to the grabbing of the outer peripheral contour of the forward optical lens is defined as a first clamp, and the clamp adapted to the grabbing of the outer peripheral contour of the reverse optical lens is defined as a second clamp. When the optical lens fed to the feeding and discharging area 111 is forward, the taking arm 122 moves to the clamp seat 170 and takes out the first clamp to perform the feeding operation on the optical lens by the first clamp; on the contrary, when the optical lens fed to the feeding and discharging area 111 is reverse, first, the taking arm 122 moves to the clamp seat 170 and takes out the second clamp, then the second clamp grabs the reverse optical lens and feeds to the turnover mechanism 140 for automatic turnover, finally, the taking arm 122 moves to the clamp seat 170 to place the second clamp on the clamp seat 170 again, and takes out the first clamp to perform the feeding operation on the turned-over optical lens.

[0055] It should be noted that the clamp is detachably connected to the taking arm 122 by clamping, magnetic attraction or the like, so that different specifications of clamps can be replaced to adapt to the grabbing operation of the forward or reverse optical lens when the taking arm 122 moves to the clamp seat 170.

[0056] In an embodiment, referring to Figures 1-3 As shown, the optical lens detection device 100 further comprises a jacking module 180 and a feeding table 181, the feeding table 181 is used for feeding and bearing the optical lens, for example, the feeding table 181 has a bearing cavity used for accommodating and bearing the optical lens. The jacking module 180 is arranged on the machine table 110, and the jacking module 180 is located at the feeding and discharging area 111. The feeding table 181 and the jacking module 180 are used for jacking the feeding table 181 to a position where the taking mechanism 120 can take and place the optical lens, that is, when the optical lens to be detected is fed to the feeding table 181, the jacking module 180 jacks the feeding table 181 to a position where the taking mechanism 120 can pick up the optical lens, so as to facilitate the taking of the optical lens by the taking mechanism 120; on the contrary, when the tested optical lens is fed to the feeding and discharging area 111 by the taking mechanism 120 from the detection area 112, the jacking module 180 jacks the feeding table 181 to a position where the taking mechanism 120 can place the optical lens, so as to facilitate the discharging of the optical lens by the taking mechanism 120.

[0057] In an embodiment, referring to Figures 1-3As shown, the optical lens detection device 100 further comprises a rotating member 190 and a code scanning module 191. The rotating member 190 and the code scanning module 191 are both arranged on the machine table 110, and are both located in the loading and unloading area 111. The rotating member 190 has at least one loading position for loading the optical lens. During the rotation of the rotating member 190, any loading position can move to a position that can be scanned by the code scanning module 191. When each loading position rotates to the position that can be scanned by the code scanning module 191, the optical lens can be scanned by the code scanning module 191 to obtain the information of the optical lens to be detected. The material taking mechanism 120 can move between the loading table 181, the rotating member 190 and the turnover mechanism 140. Through the movement of the material taking mechanism 120 between the various stations, the optical lens to be detected can be turned over, scanned and the like. For example, the material taking mechanism 120 moves to the position of the loading table 181. If the optical lens loaded on the loading table 181 is in a forward direction, the material taking mechanism 120 picks up the optical lens and sends it to the code scanning module 191 for scanning. After the optical lens is scanned, the material taking mechanism 120 feeds the optical lens to the detection area 112 for imaging quality detection. If the optical lens loaded on the loading table 181 is in a reverse direction, the material taking mechanism 120 picks up the optical lens and sends it to the turnover mechanism 140 for automatic turnover. After the optical lens is turned over, the material taking mechanism 120 sends the optical lens to the code scanning module 191 for scanning. After the optical lens is scanned, the material taking mechanism 120 feeds the optical lens to the detection area 112 for imaging quality detection.

[0058] Since the optical lens needs to image the detection pattern piece 130 in a darkroom environment, in an embodiment, referring to Figures 1-3 As shown, the machine table 110 is provided with a baffle 115 which is arranged outside the detection area 112 to separate the loading and unloading area 111 from the detection area 112, so as to create a darkroom environment in the detection area 112, so that the optical lens can image the detection pattern piece 130 in the detection area 112 to detect the imaging quality of the optical lens. The baffle 115 is arranged on the machine table 110 in a lifting manner, which facilitates the feeding operation of the optical lens between the loading and unloading area 111 and the detection area 112. For example, when the optical lens to be detected needs to be fed from the loading and unloading area 111 to the detection area 112, or the optical lens needs to be fed from the detection area 112 to the loading and unloading area 111, the baffle 115 can be lowered relative to the machine table 110, which facilitates the feeding operation of the optical lens between the loading and unloading area 111 and the detection area 112. When the optical lens needs to be imaged in the detection area 112, the baffle 115 can be raised relative to the machine table 110 to create a darkroom environment in the detection area 112, so that the optical lens can image the detection pattern piece 130 in the detection area 112.

[0059] Further, referring to Figures 1-3As shown, the machine table 110 is provided with a damping module 116, such as a gas floating marble platform. The taking mechanism 120, the detection pattern piece 130, and the turnover mechanism 140 are all arranged on the damping module 116, so as to reduce the influence of the vibration of the machine table 110 on the imaging detection of the optical lens, and improve the detection efficiency and reliability of the optical lens.

[0060] The detection method of the optical lens detection device 100 in the present application will be described in detail below. Figures 1-7 The detection method of the optical lens includes the following steps:

[0061] Step S110: The optical lens to be detected is fed to the feeding and discharging area 111. After the optical lens is fed to the feeding and discharging area 111, the positions of the optical lens and the taking mechanism 120 need to be aligned for the subsequent taking operation of the taking mechanism 120 on the optical lens.

[0062] Step S120: The second camera module 152 detects the front and back of the optical lens fed to the feeding and discharging area 111. If the optical lens is in the front direction, the taking mechanism 120 directly feeds the optical lens to the rotating piece 190 for code scanning operation. If the optical lens is in the back direction, the taking mechanism 120 moves to the turnover piece 142 and feeds the optical lens to the turnover piece 142 for turnover operation. After the optical lens is turned over, the taking mechanism 120 feeds the optical lens to the rotating piece 190 for code scanning operation.

[0063] Step S130: The taking mechanism 120 feeds the optical lens after code scanning to the carrier 161. The first alignment module 162 adjusts the carrier 161 in multiple axes, and the second alignment module 163 adjusts the imaging module 160 in multiple axes, so as to align and adjust the optical lens and the imaging module 160.

[0064] Step S140: The transfer module 114 drives the carrier 161 and the imaging module 160 to move synchronously, so as to adjust the optical lens carried by the carrier 161 to the positions of the detection pattern pieces 130. The optical lens images the detection pattern pieces 130, and the imaging module 160 captures the imaging pictures of the optical lens to detect the imaging quality of the optical lens. For example, if the detection pattern pieces 130 are three, the three detection pattern pieces 130 are defined as the first detection pattern piece 131, the second detection pattern piece 132, and the third detection pattern piece 133. The first detection pattern piece 131, the second detection pattern piece 132, and the third detection pattern piece 133 are arranged in the horizontal direction. Figure 2 The transfer module 114 drives the optical lens and the imaging module 160 to the above of the first detection pattern piece 131 in the horizontal direction, so as to image and detect the first detection pattern piece 131. Then, the transfer module 114 drives the optical lens and the imaging module 160 to the above of the second detection pattern piece 132 in the horizontal direction, so as to image and detect the second detection pattern piece 132. Finally, the transfer module 114 drives the optical lens and the imaging module 160 to the above of the third detection pattern piece 133 in the horizontal direction, so as to image and detect the third detection pattern piece 133. Figure 2 The transfer module 114 drives the optical lens and the imaging module 160 to the above of the first detection pattern piece 131 in the horizontal direction, so as to image and detect the first detection pattern piece 131. Then, the transfer module 114 drives the optical lens and the imaging module 160 to the above of the second detection pattern piece 132 in the horizontal direction, so as to image and detect the second detection pattern piece 132. Finally, the transfer module 114 drives the optical lens and the imaging module 160 to the above of the third detection pattern piece 133 in the horizontal direction, so as to image and detect the third detection pattern piece 133.Figure 2 The optical lens and the imaging module 160 are driven to above the second detection pattern piece 132 in the horizontal direction shown by the arrow, and the second detection pattern piece 132 is imaged and detected; finally, the transfer module 114 moves the optical lens to the unloading area 111 in the horizontal direction shown by the arrow, and the optical lens is unloaded. Figure 2 The optical lens and the imaging module 160 are driven to above the third detection pattern piece 133 in the horizontal direction shown by the arrow, and the third detection pattern piece 133 is imaged and detected. In this embodiment, the first detection pattern piece 131 is provided above a relay lens 138, so that when the optical lens images and detects the first detection pattern piece 131, the optical lens needs to image the first detection pattern piece 131 through the relay lens 138, thereby changing the detection environment of the optical lens and obtaining the imaging quality detection of the optical lens in a specific detection environment; and the detection area 112 is further provided with a detection light source 139, and when the optical lens moves to the detection area 112, the optical lens can receive the light beam of the detection light source 139 to detect the incident light performance of the optical lens.

[0065] Step S150: After the optical lens detection is completed, the taking mechanism 120 moves to the detection area 112, and the optical lens is fed from the detection area 112 to the unloading area 111 for unloading operation.
