Description

TECHNICAL FIELD

[0001] The utility model belongs to optical element technical field, concretely relates to a kind of lens assembly components of flip top pressure type. BACKGROUND

[0002] In the manufacture of optical equipment, communication devices and camera modules, etc., it is often necessary to precisely assemble a micro lens into the inner cavity of a tube cap to form a complete optical assembly. This assembly process requires high coaxiality and cleanliness. However, as a brittle material, the lens itself is prone to cracks, edge collapse or stress concentration during assembly due to uneven stress or mechanical clamping, resulting in a decrease in product yield.

[0003] Currently, the common assembly methods mainly include the following three types: 1. Manual assembly by human operators using tweezers and other tools under a microscope to place the lens into the tube cap. This method is low in efficiency and highly dependent on operator skills, and it is difficult to meet the needs of large-scale production. 2. Automatic assembly by robotic hands, which use multi-axis robots in combination with vacuum suction nozzles to pick up and place the lens. Although this method has a high degree of automation, it requires a large investment in motion control and vision positioning systems, and the equipment is expensive. 3. Vibration plate feeding and press-fitting method. Although this method has a certain efficiency, the lenses are prone to scratches or debris during the vibration feeding process due to mutual friction and collision. Moreover, the "top-down" press-in method is prone to lens edge impact, posing a high risk of breakage.

[0004] Chinese patent CN113376771A discloses a device and process for preparing a tube cap, which includes a lower jig, a middle jig and an upper jig. The lower jig has multiple solder grooves arranged in an array. Each solder groove is coaxially provided with a lens groove below it, and the diameter of the lens groove is smaller than that of the solder groove. The middle jig has metal tube shell grooves arranged in an array. Each metal tube shell groove is coaxially provided with a lower through hole below it, and the diameter of the lower through hole is smaller than that of the metal tube shell groove. The upper jig has multiple bosses arranged in an array. When the lower jig, the middle jig and the upper jig are stacked from bottom to top, the solder grooves, the metal tube shell grooves and the bosses are coaxially arranged one by one, the lower through hole of the metal tube shell groove communicates with the solder groove, and the boss is embedded in the upper end of the metal tube shell groove. This patent has a simple structure, is suitable for mass production, and has a low cost. However, the lens needs to be flipped 180° with the entire three-layer jig set after vibration feeding, which is cumbersome to operate. Moreover, the lens is in a loose state in the groove during the flipping process, which increases the risk of displacement or collision. Furthermore, the final coaxiality of the lens and the tube shell relies excessively on the processing accuracy of the jig, and there is a lack of active calibration mechanism during the assembly process, resulting in poor alignment consistency and high process uncertainty.
