Description

Technical Field

[0001] This invention relates to the field of optical manufacturing technology, and in particular to a vibration bonding device. Background Technology

[0002] Currently, the optical industry has many prisms, flat glass panes, and other components that require bonding, i.e., gluing two prisms or two flat glass panes together. The conventional method is to apply glue to one component, place the other component on top of the glued component, and then press it down manually or mechanically to ensure the glue is evenly spread between the two components for a strong bond. However, for ultra-thin glue layers, such as those requiring a thickness of 5 micrometers and a glue uniformity tolerance of less than 1 micrometer, conventional manual or mechanical pressing methods cannot meet these requirements.

[0003] Therefore, a vibration bonding device is needed to meet the bonding requirements of ultra-thin adhesive layers and uniformity tolerance of less than 1 micrometer. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration bonding device that can replace manual or mechanical pressing to bond upper and lower bonding parts with glue, and can ensure the required thickness and uniformity of the glue.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] A base, on which a vibrator is mounted;

[0008] A lower positioning fixture and an upper positioning fixture are provided. The lower positioning fixture is disposed on the vibrator. A lower adhesive component is disposed at one end of the lower positioning fixture facing the upper positioning fixture. The upper adhesive component and the lower adhesive component are attached to each other. The upper positioning fixture covers the lower positioning fixture. The upper adhesive component is disposed at one end of the upper positioning fixture facing the lower positioning fixture.

[0009] When the vibrator vibrates, the upper positioning fixture can move relative to the lower positioning fixture to drive the upper adhesive component to move on the lower adhesive component.

[0010] As an alternative, one of the lower positioning fixture and the upper positioning fixture is provided with a positioning hole, and the other is provided with a positioning post with the same cross-sectional shape as the positioning hole. The cross-sectional size of the positioning hole is larger than the cross-sectional size of the positioning post. When the upper positioning fixture is placed on the lower positioning fixture, the positioning post is inserted into the positioning hole.

[0011] As an alternative, the positioning hole includes at least two circular holes, and the positioning post includes a number of circular posts equal to the number of circular holes, with the plurality of circular posts capable of being inserted into the plurality of circular holes respectively.

[0012] As an optional solution, the unilateral movement distance of the upper adhesive component relative to the lower adhesive component is 0.5 mm.

[0013] As an alternative, both the lower adhesive component and the upper adhesive component are cuboid plates. The lower positioning fixture has a lower limiting portion at one end facing the upper positioning fixture, and the lower adhesive component is limited to the lower limiting portion. The upper positioning fixture has an upper limiting portion at one end facing the lower positioning fixture, and the upper adhesive component is limited to the upper limiting portion.

[0014] As an alternative, the lower limiting part includes four limiting bosses, and the four sides of the lower adhesive part respectively abut against the four limiting bosses.

[0015] As an alternative, the upper limit part includes two right-angled limiting blocks, which are arranged diagonally, and the two diagonal parts of the upper adhesive part respectively abut against the two diagonally arranged right-angled limiting blocks.

[0016] As an optional solution, the inner sides of the two right-angle limiting blocks facing each other are provided with chamfers.

[0017] As an alternative, the lower positioning fixture is provided with two mounting holes, and the vibrator is provided with two mounting posts. When the lower positioning fixture is installed on the vibrator, the two mounting posts are respectively inserted into the two mounting holes.

[0018] As an optional solution, the base is provided with an amplitude adjustment knob and a time adjustment knob. The amplitude adjustment knob can adjust the vibration amplitude of the vibrator, and the time adjustment knob can adjust the vibration time of the vibrator.

[0019] The beneficial effects of this invention are:

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of this invention, 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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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 invention according to the specific circumstances.

[0032] In the description of this invention, unless otherwise expressly 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 being 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 being 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.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-3 As shown, this embodiment of the invention provides a vibration bonding device, including a base 1, a lower positioning fixture 2, and an upper positioning fixture 3. A vibrator 11 is mounted on the base 1, capable of generating vibration. The vibrator 11 can be one of various vibration sources, such as pneumatic or electric; the vibrator 11 is not limited here. The lower positioning fixture 2 is fixedly mounted on the vibrator 11, and a lower bonding component 100 is mounted on the lower positioning fixture 2. After adhesive is applied to the lower bonding component 100, an upper bonding component 200 is placed on top of the lower bonding component 100, and the upper bonding component 200 and the lower bonding component 100 are in contact with each other. The adhesive is located on the upper bonding component 200. Between the upper positioning fixture 3 and the lower positioning fixture 200; the upper positioning fixture 3 is covered on the lower positioning fixture 2, and the upper positioning fixture 3 can move relative to the lower positioning fixture 2. The upper positioning fixture 200 is located at the end of the upper positioning fixture 3 facing the lower positioning fixture 2. When the vibrator 11 vibrates, the upper positioning fixture 3 moves relative to the lower positioning fixture 2 due to the vibration of the vibrator 11, and drives the upper positioning fixture 200 to move back and forth relative to the lower positioning fixture 100, so that the upper positioning fixture 200 has a coating effect relative to the lower positioning fixture 100.

[0035] When the vibrator 11 of the vibratory bonding device vibrates, it enables the adhesive between the upper bonding component 200 and the lower bonding component 100 to move rapidly to the surroundings, spread evenly, and thin out, so that excess adhesive can be discharged from the edges of the upper bonding component 200 and the lower bonding component 100, thus ensuring the thickness and uniformity of the adhesive. Furthermore, the upper bonding component 200 can move back and forth relative to the lower bonding component 100, so that the upper bonding component 200 has the effect of smoothing the adhesive relative to the lower bonding component 100, further improving the uniformity of the adhesive and the bonding efficiency of the upper bonding component 200 and the lower bonding component 100.

[0036] Optionally, one of the lower positioning fixture 2 and the upper positioning fixture 3 is provided with a positioning hole, and the other is provided with a positioning post with the same cross-sectional shape as the positioning hole, and the cross-sectional size of the positioning hole is larger than the cross-sectional size of the positioning post. When the upper positioning fixture 3 is placed on top of the lower positioning fixture 2, the positioning post is inserted into the positioning hole. This structure makes it easier to connect the upper positioning fixture 3 and the lower positioning fixture 2, and the upper positioning fixture 3 can move relative to the lower positioning fixture 2.

[0037] In this embodiment, the positioning holes include two circular holes 21, which are spaced apart along the length of the lower positioning fixture 2. The positioning posts include two circular posts 31, which are spaced apart along the length of the upper positioning fixture 3. The diameter of the circular holes 21 is larger than the diameter of the circular posts 31. When the upper positioning fixture 3 covers the lower positioning fixture 2, the two circular posts 31 are inserted into the two circular holes 21. When the vibrator 11 vibrates, the upper positioning fixture 3 can move relative to the lower positioning fixture 2 due to the gap between the circular posts 31 and the circular holes 21. It can be understood that the number of circular holes 21 and circular posts 31 can also be more than two.

[0038] Specifically, the diameter of the circular hole 21 is 5mm, and the diameter of the circular column 31 is 4mm. This design ensures that when the vibrator 11 vibrates, the upper positioning fixture 3 moves 0.5mm on one side relative to the lower positioning fixture 2 in all directions. That is, the upper adhesive part 200 moves 0.5mm on one side relative to the lower adhesive part 100. This movement distance ensures that the glue is spread evenly and that the offset distance between the upper adhesive part 200 and the lower adhesive part 100 is within a small range, so as to ensure the effective use area of ​​the upper adhesive part 200 and the lower adhesive part 100.

[0039] In other embodiments, the positioning holes and positioning posts have a square cross-sectional shape, and at least one set of square positioning holes and positioning posts is sufficient to meet the requirements.

[0040] In this embodiment, both the lower adhesive component 100 and the upper adhesive component 200 are rectangular glass plates. The lower positioning fixture 2 has a lower limiting portion at one end facing the upper positioning fixture 3. When the lower adhesive component 100 is placed on the lower positioning fixture 2, it is positioned within the lower limiting portion, with its four sides abutting against it. The upper positioning fixture 3 has an upper limiting portion at one end facing the lower positioning fixture 2. When the upper adhesive component 200 and the lower adhesive component 100 are fitted together, the upper positioning fixture 3 covers the lower positioning fixture 2, and the upper adhesive component 200 is confined within the upper limiting portion. This structure makes the installation of the lower adhesive component 100 and the lower positioning fixture 2 more convenient, and the fixed installation of the upper adhesive component 200 and the upper positioning fixture 3 more convenient.

[0041] Specifically, refer to Figure 2 The lower limiting part includes four limiting bosses 22. The lower adhesive part 100 is installed between the four limiting bosses 22, and the four sides of the lower adhesive part 100 abut against the four limiting bosses 22 respectively to position and fix the lower adhesive part 100. In this embodiment, two circular holes 21 are provided on the two limiting bosses 22 that are spaced apart along the length of the lower positioning fixture 2.

[0042] Reference Figure 3 The upper positioning part includes two right-angled limiting blocks 32, which are arranged diagonally. When the upper positioning fixture 3 covers the lower positioning fixture 2, the two diagonal parts of the upper adhesive part 200 abut against the two diagonally arranged right-angled limiting blocks 32. In this structure, the two inner sides of each right-angled limiting block 32 abut against the two adjacent sides of the upper adhesive part 200, making it easier to fix the upper adhesive part 200 to the upper positioning fixture 3.

[0043] Optionally, the limiting boss 22 and the right-angle limiting block 32 can also be configured to be position-adjustable to facilitate the limiting of the lower glued part 100 and the upper glued part 200 of different sizes.

[0044] To facilitate automatic alignment when the upper glued part 200 is placed within the upper limit position, the inner sides of the two right-angle limit blocks 32 are chamfered. After being guided by the chamfer, the upper glued part 200 can be quickly and accurately positioned within the upper positioning fixture 3.

[0045] Continue to refer to Figure 1 and Figure 2 The lower positioning fixture 2 is provided with two mounting holes 23, and the vibrator 11 is provided with two mounting posts 111 that cooperate with the mounting holes 23. When the lower positioning fixture 2 is installed on the vibrator 11, the two mounting posts 111 are respectively inserted into the two mounting holes 23.

[0046] To facilitate control of the vibration amplitude and duration of the vibrator 11, the base 1 is equipped with an amplitude adjustment knob 12 and a time adjustment knob 13. Rotating the amplitude adjustment knob 12 adjusts the vibration amplitude of the vibrator 11, while rotating the time adjustment knob 13 adjusts the vibration duration. This structural design allows for parameter setting according to different products, enabling the determination of the required vibration amplitude and duration to achieve the desired adhesive layer thickness and uniformity, thus ensuring the bonding quality of the product.

[0047] like Figure 4 As shown, the operating procedure of the vibration bonding device is as follows: First, place the lower bonding component 100 within the lower limit portion of the lower positioning fixture 2; then, drip glue onto the lower bonding component 100 (the glue can be dripped manually or dispensed using a dispensing machine); next, place the upper bonding component 200 on top of the lower bonding component 100, with the glue positioned between the upper and lower bonding components 100; the upper positioning fixture 3 covers the lower positioning fixture 2, and the upper bonding component 200 is positioned on the upper positioning fixture 3. Inside the upper limit section of fixture 3; turn on vibrator 11, set vibration amplitude and vibration time, so that upper glued part 200 moves back and forth relative to lower glued part 100, and at the same time, glue will flow in all directions due to vibration; when vibrator 11 stops vibrating, the glued upper glued part 200 and lower glued part 100 are obtained; the misaligned parts of upper glued part 200 and lower glued part 100 due to the gap between circular hole 21 and circular column 31 are cut by cutting equipment.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
