Description

Technical Field

[0001] This utility model relates to the field of lens assembly technology, and in particular to an assembly device with an adhesive-backed sealing ring. Background Technology

[0002] In the manufacturing process of precision instruments such as optical lenses, it is often necessary to precisely assemble micro-sealing rings with adhesive backing into specific positions inside the lens barrel to achieve functions such as sealing and dust prevention. Traditional assembly methods rely heavily on manual operation, which has significant drawbacks: First, the adhesive-backed sealing rings are prone to sticking together or to the fixture due to their stickiness, leading to difficulties in loading, inaccurate picking, or omissions; second, manual placement makes it difficult to ensure the positional accuracy and orientation consistency (such as horizontality and concentricity) of the sealing rings within the lens barrel, easily causing sealing failure or affecting optical performance; third, it is inefficient and susceptible to the effects of human fatigue. Although some automated equipment exists, it generally suffers from insufficient anti-sticking measures, low positioning accuracy, missing or inefficient calibration processes when handling micro-sealing rings with adhesive backing, making it difficult to meet the mass production requirements of high precision, high efficiency, and high yield. Utility Model Content

[0003] The purpose of this invention is to provide an assembly device with an adhesive-backed sealing ring to solve the above-mentioned problems.

[0004] According to one aspect of this utility model, an assembly device for adhesive-backed sealing rings is provided, comprising: a machine base with a control mechanism on one side; a sealing ring distributor movably disposed on the machine base along the X-axis, the sealing ring distributor being used to transfer adhesive-backed sealing rings; a feeding identification mechanism disposed above the sealing ring distributor, the feeding identification mechanism being used to identify the position of each sealing ring in the sealing ring distributor; a feeding gripping mechanism disposed above the sealing ring distributor, the feeding gripping mechanism being used to grip the sealing rings; a correction mechanism disposed on one side of the feeding gripping mechanism, the correction mechanism being used to correct the position of the sealing rings gripped by the feeding gripping mechanism; and a discharging assembly mechanism disposed on one side of the correction mechanism, the discharging assembly mechanism being used to grip and place the corrected sealing rings into a lens barrel; the control mechanism is electrically connected to the sealing ring distributor, the feeding identification mechanism, the feeding gripping mechanism, the correction mechanism, and the discharging assembly mechanism respectively.

[0005] In some embodiments, the sealing ring distributor includes a first X-axis linear motor, which is mounted on the machine base. The output end of the first X-axis linear motor is provided with a distribution plate. The distribution plate is provided with a plurality of first receiving grooves for placing sealing rings, and a first anti-stick coating is provided in the first receiving grooves.

[0006] In some embodiments, the feeding and identification mechanism includes an identification camera, the identification end of which faces the sealing ring distributor.

[0007] In some embodiments, the feeding and gripping mechanism includes a second X-axis linear motor mounted on the machine base, a first Y-axis linear motor at the output end of the second X-axis linear motor, a first Z-axis cylinder at the output end of the first Y-axis linear motor, and a first pneumatic inner support gripper at the output end of the first Z-axis cylinder. After the first pneumatic inner support gripper extends into the first receiving groove, air is supplied by the cylinder to open the first pneumatic inner support gripper to grip the sealing ring.

[0008] In some embodiments, the calibration mechanism includes a calibration platform disposed between the feeding gripping mechanism and the unloading assembly mechanism. The calibration platform has a second receiving groove in the middle for placing a single sealing ring. The second receiving groove is provided with a second anti-stick coating. Pneumatic calibration blocks are respectively disposed on both sides of the second receiving groove. The pneumatic calibration blocks on both sides can move towards or away from the second receiving groove simultaneously. Calibration grooves are provided on the opposite surfaces of the pneumatic calibration blocks on both sides. The shape of the calibration grooves is adapted to the sealing ring.

[0009] In some embodiments, both the first and second anti-stick coatings are silicone coatings, fluoropolymer coatings, or polyvinyl alcohol coatings.

[0010] In some embodiments, the unloading and assembly mechanism includes a second Y-axis linear motor and a third X-axis linear motor disposed on one side of the calibration mechanism. The output end of the second Y-axis linear motor is provided with a lens barrel tray for placing the lens barrel. The third X-axis linear motor is disposed above the second Y-axis linear motor. The output end of the third X-axis linear motor is provided with a second Z-axis cylinder. The output end of the second Z-axis cylinder is provided with a second pneumatic inner support gripper. After the second pneumatic inner support gripper extends into the second receiving groove, air is supplied by the cylinder to open the second pneumatic inner support gripper to grasp the calibrated sealing ring. The third X-axis linear motor, in conjunction with the second Z-axis cylinder, places the sealing ring on the second pneumatic inner support gripper into the lens barrel.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] Highly efficient anti-sticking and precise feeding: The sealing ring distributor is equipped with a first receiving groove with an anti-stick coating, which, together with a precisely movable dispensing plate, effectively prevents the adhesive-backed sealing rings from sticking to each other or to the material plate, ensuring reliable dispensing. The feeding identification mechanism identifies the position of each sealing ring in real time, guiding the feeding gripping mechanism to accurately grip a single sealing ring, greatly improving the accuracy and stability of feeding and avoiding missed or excessive picking.

[0013] High-precision position correction: An independent correction mechanism is set up. The feeding and gripping mechanism places the gripped sealing ring into the second receiving groove with an anti-stick coating. The pneumatic correction blocks on both sides move synchronously towards each other. The correction groove that matches the shape of the sealing ring is used to accurately position and correct its posture, completely eliminating any possible offset during gripping and transfer, and ensuring the absolute accuracy of subsequent assembly.

[0014] Reliable and non-destructive assembly: The unloading and assembly mechanism uses internal support grippers to pick up the precisely positioned sealing ring from the calibration mechanism. Through multi-axis coordinated motion, the sealing ring is smoothly and vertically pressed into the designated position inside the lens barrel on the lens barrel tray. The internal support gripping method effectively avoids damage to the adhesive backing surface of the sealing ring, ensuring the integrity of the sealing ring and its adhesive performance.

[0015] Full-process automation and high yield: The entire process is completed automatically under the coordination of the control mechanism, which significantly improves production efficiency, reduces labor costs and operational error rate. Precise positioning, effective anti-sticking and correction links together ensure high precision and consistency of the final assembly position, greatly improving product yield.

[0016] Compact structure and flexibility: All functional modules are integrated into the machine tool, with a reasonable layout and clear motion path. It adopts precision drive components such as linear motors, which have fast response speed, high positioning accuracy, and efficient and reliable overall operation.

[0017] The core advantage of this utility model lies in the fact that through the automated process of anti-sticking material distribution, visual positioning, internal support gripping, independent precision correction, and secondary internal support assembly, the core problems of adhesive-backed micro sealing rings in automated assembly, such as sticking, inaccurate positioning, and incorrect posture, are completely solved, achieving high-precision, high-efficiency, high-stability, and high-yield automated production.
