[0036] First, connect the air intake pipe 121 to an external air pump, and then place the curved lens or the flat lens on the rotating seat 6, and make the lens between the four curved positioning plates 7, then insert the hexagonal screw into the hexagonal groove of the driving rod 11, twist the hexagonal screw to drive the driving rod 11 to reverse, the reverse rotation of the driving rod 11 drives the spur gear 111 to reverse, the reverse rotation of the spur gear 111 drives the curved rack 112 to reverse, the reverse rotation of the curved rack 112 drives the circular ring 9 to reverse, the reverse rotation of the circular ring 9 drives the straight hole plate Ⅰ10 to reverse, the reverse rotation of the straight hole plate Ⅰ10 drives the four limit blocks 8 to move inward, and through the action of the inclined rod 71, the limit blocks 8 move obliquely downward, if a curved lens is placed on the rotating seat 6, the inclined surfaces of the four limit blocks 8 are in contact with the curved lens, and the four limit blocks 8 are on the curved lens The plate is limited, if a flat lens is placed on the rotating seat 6, the bottom of the limit block 8 contacts the top of the flat lens, and the four limit blocks 8 limit the flat lens, stop twisting the hexagonal screw, the driving rod 11 stops driving the spur gear 111 to reverse, the spur gear 111 stops driving the ring 9 to reverse through the arc rack 112, the ring 9 stops driving the slotted hole plate Ⅰ10 to reverse, the limit block 8 stops moving, and then the external air pump is started to discharge the air into the air intake pipe 121, the air in the air intake pipe 121 is discharged into the air guide pipe 123 through the shell 122, and the air in the air guide pipe 123 is discharged into the annular airbag 12. As the air is discharged, the annular airbag 12 continues to expand and contact the lens, and the annular airbag 12 fills the gap between the lens and the rotating seat 6. That is, the lens is supported and limited, the air pump is turned off, the air stops being discharged into the air inlet pipe 121, the annular airbag 12 stops expanding, the rodless cylinder 2 is started to drive the lifting frame 3 to move downward, the lifting frame 3 drives the friction block 4 to move downward, when the friction block 4 moves downward and contacts the lens, the rodless cylinder 2 is turned off, and then the electric lifting plate 131 is started to move upward to drive the spline shaft 132 to move upward, the spline shaft 132 moves upward and is inserted into the inner spline cylinder Ⅰ13, the electric lifting plate 131 is turned off, and the drive motor 133 is started. The drive motor 133 drives the spline shaft 132 to rotate through the synchronous belt assembly, the spline shaft 132 drives the inner spline cylinder Ⅰ13 to rotate, and the inner spline cylinder Ⅰ13 drives the rightmost rotating seat 6 to rotate through the synchronous belt assembly. The seat 6 rotates through the synchronous belt assembly to drive the remaining two rotating seats 6 to rotate. The three rotating seats 6 rotate through the limit block 8 to drive the lens to rotate. The lens rotates and rubs against the friction block 4, which also detects the wear resistance of the lens. When the lens rotates and rubs to a suitable time, the drive motor 133 is turned off, the spline shaft 132 stops rotating, and the rotating seat 6 stops driving the lens to rotate through the limit block 8. At this time, the electric lifting plate 131 is started to drive the spline shaft 132 to move downward and insert into the inner spline cylinder II 134. The electric lifting plate 131 is turned off, and the drive motor 133 is started again, so that the spline shaft 132 rotates to drive the inner spline cylinder II 134 to rotate, and the inner spline cylinder II 134 rotates to drive the disc 135 to rotate, and the disc 135 drives the contact rod 136 to rotate.The contact rod 136 drives the slotted hole plate II 137 to move left and right, the slotted hole plate II 137 drives the movable seat 5 to move left and right, the movable seat 5 drives the lens to move left and right through the rotating seat 6 and the limit block 8, the lens moves left and right and continuously performs transverse friction with the friction block 4. When the lens is transversely rubbed to a suitable time, the drive motor 133 is turned off, the spline shaft 132 stops driving the inner spline cylinder II 134 to rotate, the contact rod 136 stops driving the movable seat 5 to move left and right through the slotted hole plate II 137, the lens stops moving left and right, and then the electric lifting plate 131 is started to drive the spline shaft 132 to move upward and reset, the spline shaft 132 is out of contact with the inner spline cylinder II 134, at this time, the lens has completed the wear resistance detection of rotational friction and transverse friction, and the two types of friction can improve the accuracy of the wear resistance detection of the lens. Then start the air pump to extract the air in the annular airbag 12 through the air inlet pipe 121 and the air guide pipe 123. As the air is extracted, the annular airbag 12 continuously contracts and resets to disengage from the lens. Then start the rodless cylinder 2 to drive the friction block 4 to move upward and reset through the lifting frame 3. The friction block 4 resets and disengages from the lens. Then use the hexagonal screw to twist the drive rod 11 to reset forward. The drive rod 11 drives the spur gear 111 to reset forward. The spur gear 111 rotates forward through the arc rack 112 to drive the circular ring 9 to reset forward. The circular ring 9 drives the straight hole plate Ⅰ10 to reset forward. The straight hole plate Ⅰ10 drives the four limit blocks 8 to move outward and reset. The limit blocks 8 are out of contact with the lens, which means that the lens is loosened. Then the lens is taken down, and the operator can detect the light transmittance of the printing oil layer by visual observation and light irradiation. In this way, the plane lens and the arc lens can be quickly limited by the movement of the limit block 8 for wear resistance testing. The operation is convenient, thereby improving the detection efficiency of the lens.

[0037] See also Fig. 9 and Fig.10As shown, the camera module lens detection device also includes a pushing assembly installed on the rotating seat 6, the pushing assembly includes a pushing rack 14, a reset spring 141, a pull wire 142, a sliding seat 143 and a limit assembly, the pushing rack 14 is vertically slidably connected to the middle of the top of the three rotating seats 6, when the pushing rack 14 moves upward, the pushing rack 14 can drive the lens to move upward, the reset spring 141 is connected between the bottom of the pushing rack 14 and the inner side of the rotating seat 6, the top of the rotating seat 6 is symmetrically slidably connected to the sliding seat 143, the lower part of the sliding seat 143 is connected to the pull wire 142, the tail ends of the two pull wires 142 slide through the rotating seat 6 and are fixedly connected to the lower part of the pushing rack 14, the sliding seat 14 A limiting assembly is arranged between the rotating seat 3 and the rotating seat 6. When the limiting assembly is in operation, the limiting assembly can limit the sliding seat 143. The limiting assembly includes a rubber strip 144, a rubber block 145 and a connecting spring 146. Two groups of rubber strips 144 are symmetrically fixed to the rotating seat 6. The number of each group of rubber strips 144 is two. Each group of two rubber strips 144 is located on both sides of the sliding seat 143. The upper part of the sliding seat 143 is symmetrically slidably connected with the rubber block 145. The rubber block 145 is in contact with the rubber strip 144. The rubber block 145 can limit the sliding seat 143. A connecting spring 146 is symmetrically connected between the two rubber blocks 145 on the sliding seat 143.

[0038] When the lens wear resistance test is completed, it is inconvenient for the operator to remove the lens because the lens is tightly attached to the rotating seat 6. At this time, the sliding seat 143 is pushed to move toward the center of the rotating seat 6, and the sliding seat 143 drives the rubber block 145 to slide on the rubber strip 144. The sliding seat 143 also drives the pull wire 142 to move. The pull wire 142 moves through the rotating seat 6 to drive the push rack 14 to move upward, the reset spring 141 is stretched, and the push rack 14 moves upward to contact the lens. The push rack 14 pushes the lens to move upward and disengage from the rotating seat 6, and the lens stops. The sliding seat 143 is pushed to move. Due to the action of the connecting spring 146, the rubber block 145 is in close contact with the rubber strip 144. The rubber block 145 and the rubber strip 144 cooperate to limit the sliding seat 143, and the sliding seat 143 can be released to remove the lens from the push rack 14. When all the lenses are removed, the sliding seat 143 is pushed to move away from the center of the rotating seat 6 to reset. The sliding seat 143 drives the pull wire 142 to move and reset. The pull wire 142 is in a relaxed state. Due to the action of the reset spring 141, the push rack 14 moves downward to reset. In this way, it can prevent the lens from being closely attached to the rotating seat 6 and making it difficult to remove, thereby facilitating the removal of the lens.

[0039] See also Fig.11 As shown, the camera module lens detection device also includes a blocking cloth 15, and the blocking cloth 15 is connected between the upper parts of the left and right side surfaces of the movable seat 5 and the upper parts of the left and right side surfaces inside the workbench 1, respectively, and the blocking cloth 15 can block foreign debris.

[0040] When the movable seat 5 moves left and right, the movable seat 5 drives the blocking cloth 15 to move left and right. The blocking cloth 15 can block foreign debris, so that the foreign debris can be prevented from falling into the inside of the workbench 1 to affect the movement of the movable seat 5, thereby ensuring the normal movement of the movable seat 5.
