Description

Technical Field

[0001] This utility model relates to the field of high-speed BOX device packaging and production technology, and in particular to a LENS dispensing anti-overflow device. Background Technology

[0002] Fiber optic communication technology is developing rapidly, and devices used in fiber optic communication are all evolving towards higher CPO (Content-Based Object) standards. Current BOX-packaged high-speed optical devices have increasingly higher requirements for precision and cleanliness, while component size is decreasing. The components of high-speed devices are also relatively expensive. If the lens adhesive does not meet quality requirements, the product yield will be low, and rework involving scraping adhesive will result in pointless work and low efficiency. Mass production is not feasible, meaning automation is impossible, and scraping adhesive and rework will significantly increase production costs.

[0003] The existing conventional dispensing methods are as follows:

[0004] 1. First, apply glue to the holder. When inserting the lens, the glue will be squeezed to the bottom. You need to scrape off any excess glue at the bottom. 2. Apply glue from the top of the lens. The glue will overflow into the bottom of the lens along the gap. The top will be 100% glued.

[0005] Both of the above methods involve manual dispensing of adhesive, which has the following drawbacks:

[0006] 1. Lenses need to be inspected and glue removed almost 100% of the time; 2. Lenses may be scratched accidentally during inspection and glue removal, resulting in scrap; 3. It is a purely manual operation and is not suitable for large-scale production. Utility Model Content

[0007] To address the problems of non-compliance of LENS adhesive with quality requirements, low product yield, and inefficient rework due to worthless glue scraping in existing conventional dispensing methods, this utility model provides a LENS dispensing anti-overflow device.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A LENS dispensing anti-overflow device includes a tray and a pressing pin. The tray has several placement slots evenly distributed longitudinally and transversely for placing product holders. Each product holder has a mounting hole for mounting product LENS, and the bottom diameter of the mounting hole is smaller than the diameter of the product LENS. The bottom of each placement slot is connected to a positioning slot that penetrates the tray, and the diameter of the positioning slot is smaller than that of the placement slot. The pressing pin has a base consisting of a limiting part that mates with the placement slot. One end of the limiting part has a counterweight, and the other end has an extension, the diameters of which are smaller than the positioning slot. The end of the extension has a pressing part with a diameter smaller than that of the mounting hole, used to press down on the product LENS.

[0010] Preferably, the length of the extension on the top pressure pin is greater than the height of the positioning groove, so that when the top pressure pin is combined with the tray, the top pressure part is located outside the tray, which makes it easier to press the product LENS.

[0011] Preferably, the end of the pressing part is an arc surface with a smooth surface treatment to prevent damage to the product LENS when pressing it.

[0012] Preferably, the top of the tray is provided with a groove and the bottom is provided with a boss, and the placement groove and the positioning groove are both located in the groove and the boss. The groove and the boss cooperate to facilitate the stacking of two trays.

[0013] Preferably, the placement slot and positioning slot on the tray are longitudinally connected, which facilitates the placement and removal of the product holder and top pressure pin into the placement slot.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model uses a uniform tray, along with pressure pins installed in either the forward or reverse direction, to lift or press down the product lenses, achieving anti-overflow dispensing. By replacing different pressure pins, it can adapt to dispensing different types of lenses, offering greater flexibility. The number of bases and pressure plates can be configured as needed, allowing for flexible operation. The trays in the base, pressure plates, and support plates are all identical workpieces, ensuring processing accuracy and further reducing assembly errors. Manual dispensing and batch automatic dispensing can be selected according to production volume, further improving efficiency. Compared with existing technologies, it effectively solves the problem of adhesive adhesion to products with special structures in traditional dispensing. It also features a simple structure, strong scalability, significantly improved yield during operation, effectively reduced product manufacturing costs, and allows for automated mass production.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] like Figures 1 to 8As shown, this embodiment of the utility model includes a tray 1 and a pressing pin 4. The tray 1 has several placement slots 102 evenly distributed longitudinally and transversely for placing a product holder 2. The product holder 2 is provided with a mounting hole 201 for installing a product lens 3, and the bottom diameter of the mounting hole 201 is smaller than the diameter of the product lens 3. The bottom of the placement slot 102 is connected to a positioning slot 103 that penetrates the tray 1, and the diameter of the positioning slot 103 is smaller than the placement slot 102. The pressing pin 4 is based on a limiting part 401 that is inserted into the placement slot 102. One end of the limiting part is provided with a counterweight part 402, and the other end is provided with an extension part 403. The diameter of the counterweight part 402 and the extension part 403 is smaller than the diameter of the positioning slot 103. The end of the extension part 403 is provided with a pressing part 404, and the diameter of the pressing part 404 is smaller than the diameter of the mounting hole 201, for pressing the product lens 3.

[0029] like Figure 6 As shown, the product Holder2 is placed into the placement slot 102 in the tray 1 in sequence, filling the entire tray 1. Then, the product LENS3 is placed into the mounting hole 201 of the product Holder2 in the tray 1 in sequence. This combination is defined as a tray.

[0030] like Figure 7 As shown, the top pressure pin 4 is placed in the placement slot 102 in the tray 1 with the counterweight part 402 facing down in the positioning slot 103. After the entire tray 1 is filled, the top pressure pin 4 is glued or fixed to the tray 1 by other means. This combination is defined as the base.

[0031] like Figure 8 As shown, the top pressure pin 4 is placed in the placement groove 102 in the tray 1 in reverse, that is, the extension 403 is placed in the positioning groove 103 with the extension facing down. After the entire tray 1 is filled, the top pressure pin 4 is glued or fixed to the tray 1 by other means. This combination is defined as the pressure plate.

[0032] When dispensing adhesive onto products Holder2 and Lens3, place the tray onto the base positioning plate, such as... Figure 9 As shown, the pressing part of the pressing pin 4 in the base pushes the LENS3 upwards, exposing most of the LENS4. At this time, glue is applied to the sides of the LENS4 and the grooved part on the top of the Holder 2. Because the glue is applied near the bottom and middle of the LENS3, there will be no glue on the top of the LENS3. After the glue is applied, the tray is removed, and the LENS3 slides upwards by gravity. A layer of glue is applied to the cylindrical surface of the LENS3, thus achieving the effect of preventing glue spillage.

[0033] To prevent the LENS3 product from falling out of place, place the pressure plate on the tray. Figure 10As shown, under the action of gravity, the top pressure pin 4 on the pallet automatically completes the pressing action of the product LENS3, realizing the automatic pressing of the product LENS3, ensuring that each one is pressed into position, and reducing the manual pressing action of personnel one by one.

[0034] When performing automated dispensing, first place the base on the positioning table of the automatic dispensing machine and fix it, then place the tray on the base and fix it. The product LENS3 on the tray is pushed out. Then start the automatic dispensing machine to dispense the product. After dispensing is completed, place the pressure plate on the tray to complete the automatic pressing action of the product LENS3. While the automatic dispensing machine is working, you can place a new tray and then alternate with the tray that has been dispensed to complete the automatic dispensing.

[0035] Preferably, the length of the extension on the top pressure pin 4 is greater than the height of the positioning groove 103, so that when the top pressure pin 4 is combined with the tray 1, the top pressure part 404 is located outside the tray 1, which makes it easier to press the product LENS3.

[0036] Preferably, the end of the pressing part 404 is an arc surface with a smooth surface treatment to prevent damage to the LENS3 product when pressing it.

[0037] Preferably, the top of the tray 1 is provided with a groove 101 and the bottom is provided with a boss 104, and the placement groove 102 and the positioning groove 103 are both located in the groove 101 and the boss 104. The groove 101 and the boss 104 cooperate to facilitate the stacking of two trays 1.

[0038] Preferably, the placement slot 102 and the positioning slot 103 on the tray 1 are longitudinally connected, which facilitates the placement and removal of products Holder 2 and top pressure pin 4 into the placement slot 102.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
