Description

Technical Field

[0001] This utility model relates to a square filter dispensing and assembly device. Background Technology

[0002] Typically, lenses use circular filters, which are assembled by applying adhesive around the entire circumference within the lens's dispensing groove. Square filters, however, require dispensing in all four dispensing grooves of the lens before being attached. In existing technology, the alignment of the dispensing within the lens barrel relies on a vision inspection system, which is not only delicate and prone to damage but also costly. Furthermore, during the conveyor belt transport of the filters to the dispensing assembly station, vibrations and other factors can cause the filters to become slightly misaligned after being picked up by the suction tube. Without correction, these filters cannot be properly attached to the lens barrel.

[0042] In this embodiment of the invention, the alignment component, the dispensing component, and the filter correction component are arranged sequentially at intervals along the same lateral direction.

[0043] In this embodiment of the invention, the working principle of the square filter dispensing and assembly device is as follows:

[0044] First, the lens main tube at the loading station is placed into the adsorption tank, with the glue dispensing groove 16B and square groove 17B of the lens main tube 15B facing upwards. The first drive assembly pushes the movable seat to the glue dispensing alignment station.

[0045] Then, the lifting frame descends to the set height, causing the attachment head to contact the top of the lens main tube. After contact, the lifting base moves upward relative to the lifting frame, and the tension of the spring decreases. The alignment process involves the following two scenarios:

[0046] Scenario 1: When the lens main tube angle is consistent with the attachment head, the attachment head will be successfully inserted into the square groove.

[0047] Scenario 2: When the lens main tube angle and the attachment head are inconsistent, the attachment head cannot be inserted into the square groove.

[0048] In both of the above scenarios, assuming the set height for the lowering of the lifting frame is the same, the upward travel of the lifting seat relative to the lifting frame, as sensed by the first sensor, is different in both scenarios.

[0049] Therefore, in scenario one, when the angle of the square groove of the lens is consistent with that of the attachment head, after the lifting frame descends, the attachment head will smoothly embed into the square groove. At this time, the upward displacement of the lifting base relative to the lifting frame is small. The positioning sensor (first sensor) senses this small relative displacement and outputs a signal, causing the alignment motor to rotate a certain angle. The attachment head, along with the lens main barrel, rotates to the dispensing angle. After the lifting frame rises, the alignment is completed.

[0050] Scenario 2: When the angle of the lens square slot and the angle of the attachment head are inconsistent, the attachment head cannot be inserted into the square slot. In this case, the upward displacement of the lifting base relative to the lifting frame is large. The positioning sensor (first sensor) detects this large relative displacement, causing the alignment motor to temporarily stop rotating. Instead, after the lifting frame moves upward and resets, the alignment motor controls the attachment head to rotate a certain angle, and then it descends again for alignment. Before the attachment head is inserted into the square slot, the above actions are repeated. Before each descent, the attachment head rotates a certain angle until the descending attachment head can be inserted into the lens square slot. The positioning sensor (first sensor) detects this small relative displacement and outputs a signal. The control system calculates the difference between the current angle and the dispensing angle (based on the difference between the rotation angle of the alignment motor at the time of insertion and the set dispensing angle, it determines how many degrees the alignment motor still needs to drive the lens to rotate). The alignment motor rotates by this difference angle to the dispensing angle, and the attachment head, carrying the lens main barrel, rotates to the dispensing angle. After the lifting frame rises, the alignment is complete.

[0051] The angular error caused by the attachment head embedding process can be compensated for by setting the dispensing angle of the dispensing machine. If the attachment head still cannot be embedded after rotating 360 degrees, the system will alarm that the lens alignment is abnormal, and manual confirmation is required.

[0052] Before the lens main barrel is rotated to the dispensing angle, it is not vacuum-adsorbed in the adsorption tank, which facilitates the rotation and adjustment of the lens main barrel. After the lens main barrel is rotated to the dispensing angle, vacuum adsorption positions the lens main barrel in the adsorption tank.

[0053] Next, the dispensing process begins. The laterally moving dispensing assembly aligns with the dispensing slots. After the dispensing head completes dispensing into one slot, the second drive assembly rotates the shaft, suction base, and lens barrel synchronously by 90 degrees. The dispensing head then dispenses into the next slot, repeating this process until all slots are filled with adhesive. Throughout the dispensing process on the lens barrel, it remains firmly attached to the suction slot.

[0054] Finally, the filter attachment begins. The laterally moving filter alignment assembly aligns with the dispensing groove. After a filter is picked up by the suction port at the bottom of the suction tube, the two alignment plates move closer together, so that the alignment port contacts the edge of the filter and corrects its posture, ensuring accurate filter attachment and improving the yield rate of filter attachment on the lens main tube.

[0055] When the filter is attached, the suction tube is lowered by the suction tube lifting cylinder and attached to the square assembly area of ​​the lens main tube below. After the attachment is completed, the suction of the suction tube disappears and the filter correction assembly is reset.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
