Description

[0001] APPARATUS AND METHOD FOR ASSEMBLING LENS [0002]

The present invention relates to an apparatus and a method for assembling a lens, and more particularly to a lens assembling apparatus and method for matching the center of a lens and a lens barrel with each other so as to improve the degree of conformity of a lens stacked on the lens barrel.

Generally, compact camera lens modules are used in small portable products such as cellular phones, computers, tablets, and PDAs.

The mobile camera module lens is provided with four or more lenses (first to fourth lenses) in the barrel in order to realize more than 8 mega pixels (8 Mega pixels), and between the first to fourth lenses, a shield disposed on the final lens (fourth lens) is provided with an ultra violet bond to fix the lens barrel to the lens barrel, The assembly process of the camera lens module is completed.

The number of lenses and components to be assembled to the barrel is changed according to the pixel to be implemented.

Conventional mobile camera lens module assembling apparatuses are provided with pick-up means for picking up lenses and parts (masks, spacers, shields, etc.) on a pick and place apparatus and then inserting them into the lens barrel.

The pickup means of the lens assembling apparatus picks up a lens to be installed on the lens barrel by a vacuum suction type and then moves to the vision camera position to confirm the center position of the barrel housed in the pocket of the barrel tray, The center of the lens barrel was automatically adjusted by a motor, and then the lens was inserted into the lens barrel.

When the lens barrel tray having a predetermined number of barrels is transported to the assembling position of the mobile camera lens assembling device, the center of the barrel to be assembled with the lens is inspected by a vision camera installed at a lower portion of the barrel- The position of the lens barrel tray is adjusted in the X- and Y-axes so that the position is within the tolerance range, and then the first lens to be positioned on the lowermost side of the lens barrel is sucked from the lens tray to the pickup means, The first lens is moved to the upper part of the barrel, and then the first lens is inspected by a vision camera installed above and the first lens is positioned within a tolerance range.

Korean Registered Utility Model Registration No. 20-0427465 (design name: plastic injection lens assembling apparatus) discloses a structure in which a plastic injection molding lens can be automatically inserted into a lens barrel and inserted and assembled.

However, in the lens assembling apparatus according to the related art, since the lens press-in portion where the lens is picked up is lowered to press the lens into the lens barrel to complete the lens assembly, it is impossible to confirm whether the lens is properly assembled to the lens barrel.

In addition, the lens assembly apparatus according to the related art has a problem in that the optical axes of the lenses are not aligned after the lens assembly is completed by assembling the lens assemblies without checking whether the center axes of the lenses coincide with each other in the course of stacking a plurality of lenses.

In addition, the lens assembly apparatus according to the related art has a problem that productivity is reduced due to an increase in a defect rate due to an optical axis mismatch of an assembled lens.

c) When the control unit 150 moves the pickup unit 130 to pick up the lens 320 of the lens tray 300, the lens 320 picked up from the image of the picked- The central axis of the lens 320 picked up by the pick-up unit 130 is shifted from the central axis of the lens barrel 220 according to whether the center axis position of the lens 320 picked up by the pick- Correcting the position of the picked-up lens so as to coincide with the central axis of the picked-up lens; And
d) inserting the picked up lens (320) so that the picked up lens is seated on the lens barrel (220) by moving the pickup (130) according to the correction value.
10. The method of claim 9,
Wherein the step a) further includes the step of storing the image of the taken lens barrel 220 and the central axis information of the analyzed lens barrel 220 and displaying the information through the display unit 160 .
10. The method of claim 9,
Wherein the step b) further includes the step of storing the image of the photographed lens 320 and the central axis information of the analyzed lens 320 and displaying the central axis information through the display unit 160 .
10. The method of claim 9,
Wherein the step c) further comprises the step of storing the image of the taken-up pickup lens and the error information according to the position of the corrected lens 320 and displaying the result through the display unit 160 .
