Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and by way of embodiments. For ease of description, only the parts related to this utility model are shown in the drawings, not the entire structure.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] Please see Figures 1-6 This embodiment proposes a PSA dispensing assembly tool for nose pads, comprising: The base plate 1 serves as the supporting foundation for the entire tooling, providing a stable load-bearing platform for the entire device. Two spaced-apart inclined block mounting plates 2 are installed on one side of the base plate 1. These plates, along with the base plate 1, are made of AL6061 material, which possesses good strength and corrosion resistance, effectively ensuring the service life of the tooling. The base plate 1 and the inclined block mounting plates 2 are connected by welding or bolts.

[0027] The platform 3, bolted to the base plate 1, serves as a transitional load-bearing element. A second carrier plate 4, bolted to the platform 3, has first handles 41 on both sides for easy handling by operators. When the second carrier plate 4 needs to be replaced to accommodate different nose pad sizes, simply unfasten the bolts between the platform 3 and the second carrier plate 4 to easily move the second carrier plate 4 as a whole, improving the versatility and flexibility of the tooling.

[0028] Two symmetrically distributed nose pad positioning components 5 on the second carrier plate 4 can accurately position the nose pads, ensuring the accuracy of the nose pads' position during assembly. The nose pad pressing components 6 on the inclined block fixing mounting plate 2 correspond one-to-one with the nose pad positioning components 5. After the positioning film is placed on the nose pad pressing components 6, the pressing operation can accurately press the positioning film onto the nose pads, completing the assembly.

[0029] As a crucial technical feature of this embodiment, the nose bridge pressing assembly 6 includes a first carrier plate 61 with a hanging groove for easy hanging on the inclined block fixing mounting plate 2. A secure connection is then achieved by bolts securing it to the back of the inclined block fixing mounting plate 2. A buffer assembly is provided at the bottom of the first carrier plate 61 on the front side of the inclined block fixing mounting plate 2. This buffer assembly includes guide posts and springs 62 sleeved on the guide posts. This structure provides buffering and resetting functions. The lower end of the springs 62 abuts against the base plate 1, and the upper end of the springs 62 abuts against the first carrier plate 61. During the pressing operation, this ensures uniform pressing force and improves assembly quality. A height limiting block can also be provided between the two sets of springs 62. This height limiting block is fixed to the base plate 1 and located below the first carrier plate 61, providing a rigid limiting function.

[0030] A pressing plate 63 is hinged to the upper end of the first carrier plate 61. This pressing plate 63 can be flexibly rotated along the hinge axis. A first adjusting assembly 66 is bolted to the pressing plate 63, facilitating the installation and position adjustment of the positioning membrane fixture 64. The positioning membrane fixture 64 is mounted on the first adjusting plate 661 of the first adjusting assembly.

[0031] A further embodiment includes a first adjusting component 66 comprising a plurality of first waist holes 662 disposed on a pressing plate 63. Bolts pass through the first waist holes 662 and are threadedly connected to a first adjusting plate 661, allowing the first adjusting plate 661 to be adjusted within the range defined by the first waist holes 662. A first fixing plate 663 is fixedly disposed on one side of the pressing plate 63, and a first adjusting bolt 664 is disposed on the first fixing plate 663. The first adjusting bolt 664 is threadedly connected to one side of the first adjusting plate 661. In use, the position of the first adjusting plate 661 can be adjusted by adjusting the first adjusting bolt 664, thereby achieving fine adjustment of the position of the positioning film fixture 64, ensuring that the positioning film can be accurately pressed onto the nose pad, and improving assembly accuracy and quality.

[0032] The positioning film fixture 64 has a first boss, and the upper surface of the first boss has a positioning film contour groove 641. The positioning film contour groove 641 is precisely designed according to the actual shape of the positioning film. This design can ensure that the positioning film fits perfectly with the contour groove when it is placed.

[0033] A first pneumatic connector 65 is provided on the back of the positioning film fixture 64. Air passages communicating with the positioning film contour groove 641 are distributed within the positioning film fixture 64. The first pneumatic connector 65 is connected to an external vacuuming device via an air pipe. When the vacuuming device is operating, it generates an adsorption force in the positioning film contour groove 641, thereby firmly adsorbing the positioning film.

[0034] A set of pins 642 are also provided on the positioning membrane fixtures 64 located on both sides of the positioning membrane contour groove 641, which play a crucial role in fixation. The pins 642 not only accurately fix the two sides of the PSA membrane, but also ensure that after the PSA membrane is installed, the middle area, which serves as the positioning membrane, is exactly above the positioning membrane contour groove 641. The middle area of ​​the PSA membrane is the positioning membrane that needs to be pressed against the nose pad, and its edge area is used for positioning.

[0035] Subsequently, the positioning film is firmly fixed by the vacuum adsorption force of the positioning film contour groove 641, which provides a reliable guarantee for the subsequent precise pressing and assembly with the nose pad, effectively improving assembly efficiency and product quality.

[0036] To further enhance the ease of use of the pressing plate 63, a second handle 67 is provided at the front end of the pressing plate 63. Since the positioning film is adsorbed onto the positioning film contour groove 641, the operator can quickly and accurately manually press down the pressing plate 63 by holding the second handle 67. This operation can simultaneously complete the positioning and tearing processes of the PSA film, streamlining the originally cumbersome process. Through actual testing and optimization, this tooling can control the entire operation cycle time to within 35 seconds, significantly improving production efficiency and reducing labor and time costs.

[0037] Meanwhile, to precisely control the pressing degree of the pressing plate 63 and prevent it from being pressed too much or too little, a floating structural block 68 is added to the first carrier plate 61. The protrusion of the floating structural block 68 is ingeniously designed, and the shoulders on both sides are horizontally distributed, with corresponding grooves on the pressing plate 63.

[0038] When the pressing plate 63 is pressed down, its surface fits tightly against the shoulder of the floating structural block 68, effectively limiting excessive downward movement of the pressing plate 63. Simultaneously, the elastic linkage of the spring 62 provides an upward buffering force for the pressing plate 63 during the pressing process. This combined design allows for a fine-tuning range of ±0.02mm when the positioning film and nose pad are pressed together, effectively compensating for material deformation caused by various factors, ensuring assembly accuracy, and improving product quality.

[0039] As an important and essential technical feature of this embodiment, the nose pad positioning component 5 includes a nose pad contour base 51 and three sets of adjustment components distributed around the nose pad contour base 51, namely adjustment component A52, adjustment component B53, and adjustment component C54. Adjustment component A52 is used to adjust the left and right position of the nose pad contour base 51; adjustment components B53 and adjustment components C54 are used to tension and adjust the nose pad carrier 7. The nose pad carrier 7 has the required nose pad in the middle, and positioning holes on both sides for positioning, one of which is a waist hole.

[0040] Specifically, the nose pad contouring seat 51 has a second protrusion, and the upper surface of the second protrusion has a nose pad contouring groove 511. The nose pad contouring groove 511 is precisely designed according to the actual shape of the nose pad. This design can ensure that the nose pad fits perfectly with the contouring groove when placed, achieving precise positioning.

[0041] A second pneumatic connector 55 is provided on one side of the nose pad contouring seat 51, and an air passage communicating with the nose pad contouring groove 511 is distributed in the nose pad contouring seat 51. The second pneumatic connector 55 is connected to an external vacuuming device through an air pipe, so that the nose pad contouring groove 412 has an adsorption force, which can further stabilize the nose pad and ensure assembly quality.

[0042] A further implementation scheme includes an adjustment seat A521 bolted to the second carrier plate 4, ensuring a secure installation. Several second oblong holes in the left-right direction are provided on the nose pad contour seat 51, providing space for position adjustment. Bolts pass through these second oblong holes and are threadedly connected to the second carrier plate 4, allowing the nose pad contour seat 51 to move flexibly within a defined range. A second adjustment bolt 522 on the adjustment seat A521 is threaded to one side of the nose pad contour seat 51. By rotating the second adjustment bolt, the operator can precisely fine-tune the left-right position of the nose pad contour seat 51, meeting the positioning requirements of different nose pad sizes and improving assembly accuracy and product quality.

[0043] A further embodiment includes an adjusting assembly B53 comprising an adjusting seat B531 bolted to the second carrier plate 4, ensuring a secure installation of the adjusting seat B531. A third adjusting bolt 532 is provided on the adjusting seat B531, one end of which is connected to the first limiting block 533. Several front-to-back third oblique holes on the first limiting block 533 allow for position adjustment; the bolt passes through these third oblique holes and is threadedly connected to the second carrier plate 4, allowing the first limiting block 533 to move within a defined range.

[0044] Similarly, the adjusting assembly C54 includes an adjusting seat C541 bolted to the second carrier plate 4, ensuring that the adjusting seat C541 is securely installed. A fourth adjusting bolt 542 is provided on the adjusting seat C541, one end of which is connected to the second limiting block 543. Several fourth oblique holes in the front-rear direction are provided on the second limiting block 543, providing room for position adjustment. The bolt passes through the fourth oblique holes and is threadedly connected to the second carrier plate 4, allowing the second limiting block 543 to move flexibly within a limited range.

[0045] Positioning posts are respectively provided on the first limiting block 533 and the second limiting block 543. The two ends of the nose pad 7 are locked to the corresponding positioning posts by bolts passing through the positioning holes. The operator can adjust the position of the nose pad 7 by adjusting the third adjusting bolt and the fourth adjusting bolt, so that the nose pad on it is directly above the nose pad contour groove 511, and then adsorb it onto the nose pad contour groove 511 by vacuuming.

[0046] In use, after pre-adjusting the positions of the nose pad contour groove 511 and the positioning film contour groove 641, install the corresponding nose pad carriers and PSA films into place and allow them to adhere. Quickly press down the pressing plate 63 to ensure the positioning film and nose pad are fully bonded, and hold the pressure for 3 seconds to ensure adhesion strength. After completion, remove the assembled product.

[0047] The nose pad PSA dispensing assembly fixture provided by this utility model features rounded corners on all edges with a radius ≥0.5mm, countersunk screws, and polished surfaces in contact with the material to effectively prevent scratches on the FPC. Additionally, a sorting area with multiple cable tie holes is provided in the center of the base plate 1 to organize the air tubing connected to the second pneumatic connector 55 and prevent misalignment.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model.
