Description

Technical Field

[0001] This utility model belongs to the field of glue applicator technology, and in particular relates to a precision glue applicator. Background Technology

[0002] When bonding wafers and semiconductor devices to gas microwafers or microdevices, due to their extremely small size (typically on the millimeter scale) and light weight, it is often necessary to coat the wafer with a small amount of adhesive or encapsulation material under the assistance of a microscope.

[0003] Because the precision requirements for coating areas in semiconductor wafers are extremely high, conventional handheld brush coating methods are prone to problems such as misalignment, missed coating, and over-coating in localized areas. The main reason for this is the difficulty in controlling the specific coating area. To address these issues, CN201855777U discloses a wafer coating device. This device relies primarily on a coating mechanism, a self-control computer, and a microscope, resulting in a complex structure and relatively high operating costs due to its machine-based operation. Providing an auxiliary coating tool that allows for manual determination of the coating area and efficient brushing would significantly improve coating accuracy and efficiency, while also offering lower operating costs and greater convenience compared to purely machine-based methods. Therefore, this technical solution proposes a precision coating applicator. Utility Model Content

[0004] This invention provides a precision glue applicator, which includes a base with a limiting groove. Two limiting blocks are installed in the limiting groove, allowing a support rod to slide stably within the range formed by the two limiting blocks. A scale on the surface of the base serves as the positioning calibration for the limiting blocks. An adjusting arm is mounted on the support rod via a clamp, and the end of the adjusting arm holds a disposable glue brush via a spring clamp. Both the adjusting arm and the clamp have a tension adjustment structure. During glue application, the brush head of the disposable glue brush contacts the surface of the object to be glued, and the path of the support rod moving within the limiting groove is the brush head's application path. In summary, the required glue application length can be recorded by microscopic observation and converted into the limiting length formed by the limiting blocks on the limiting groove. When the support rod slides stably within the limiting groove, the sliding path is the path of the brush head on the surface of the object to be glued, thus achieving precise glue application and reducing the likelihood of misalignment, missed application, glue leakage, and over-coating in localized areas. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The present invention provides a precision glue applicator, comprising a base with a limiting groove, a limiting block installed in the limiting groove, a support rod slidably installed in the limiting groove, an adjusting arm fixed to the support rod by a clamp, and a spring clamp installed at the front end of the adjusting arm for holding a disposable glue applicator brush.

[0007] The support rod slides within the limiting groove, and the length of the adhesive application path is limited by two limiting blocks set at the front and rear.

[0008] When applying adhesive, the brush head of the disposable adhesive brush contacts the surface of the object to be coated, and the path of the support rod moving within the limiting groove is the brush head coating path.

[0009] Furthermore, the limiting groove is a long rectangle, and a scale is provided along the limiting groove on the surface of the base.

[0010] Furthermore, the bottom of the support rod is equipped with two sets of pulleys respectively through two layers of brackets. The upper and lower surfaces of the support rod are respectively provided with sliding grooves corresponding to the two sets of pulleys. The pulleys fit against the inner wall of the sliding groove, driving the support rod to move within the sliding groove.

[0011] Furthermore, the limiting block is a long strip with a length greater than the width of the limiting groove. A bolt runs through the surface of the limiting block and connects to the bottom connecting block. The bottom end of the bolt is threaded to the threaded hole on the surface of the connecting block, or the bottom of the bolt is fixedly connected to the connecting block and the top of the bolt is provided with a nut for hand-tightening connection.

[0012] Furthermore, the connecting block is embedded in a groove on the bottom surface of the base, and the connecting block is a long strip with a length greater than the width of the limiting groove, and the connecting block fits against the inner wall of the groove.

[0013] Furthermore, the bottom surface of the base is provided with a rectangular opening that matches the projected shape of the limiting groove for bolts to pass through.

[0014] Furthermore, both the adjusting arm and the clamp have a tension adjustment structure.

[0015] The present invention has the following advantages over the prior art:

[0016] (1) Simple structure and easy to use: The glue applicator includes a base with a limiting groove, two limiting blocks are installed in the limiting groove, a support rod is slidably fitted in the limiting groove, an adjusting arm is installed on the support rod by a clamp, and a disposable glue applicator brush is held at the end of the adjusting arm by a spring clamp; the glue applicator has a simple structure, is easy to install and use, and has low manufacturing cost.

[0017] (2) It can achieve precise glue application: The support rod slides stably within the range formed by the two limit blocks, and the scale on the base surface serves as the positioning calibration of the limit blocks. An adjustment arm is installed on the support rod through a clamp, and the end of the adjustment arm holds a disposable glue brush through a spring clamp. Both the adjustment arm and the clamp have a tension adjustment structure. When applying glue, the brush head of the disposable glue brush abuts against the surface of the object to be glued. The path of the support rod moving in the limit groove is the brush head application path. The required glue application length can be recorded by microscopic observation and converted into the limit length formed by the limit blocks on the limit groove. After the support rod slides stably in the limit groove, the sliding path is the path of the brush head application on the surface of the object to be glued, thereby achieving precise glue application and making it less likely to cause misalignment, missed application, glue leakage, and over-coating in local areas.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "inner", "front end", "front and back", "surface", "upper and lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1-5 As shown, this utility model discloses a precision glue applicator, comprising a base 1 with a limiting groove 11, a limiting block 3 installed in the limiting groove 11, a support rod 2 slidably installed in the limiting groove 11, an adjusting arm 22 fixed to the support rod 2 by a clamp 21, and a spring clip 23 installed at the front end of the adjusting arm 22 for holding a disposable glue brush 24; the base 1 is a rectangular block with a certain thickness; the limiting groove 11 is a long rectangle, and a scale 12 is provided along the limiting groove 11 on the surface of the base 1; the scale 12 has a 0 mark at the starting position;

[0030] The support rod 2 slides within the limiting groove 11, and the length of the adhesive application path is limited by two limiting blocks 3 set at the front and rear.

[0031] Adjusting arm 22 Figure 1As shown, both the adjusting arm 22 and the clamp 21 have a tension adjustment structure, which is a multi-segment connecting arm structure. The arms are hinged together by a first hinge structure 221 with tension adjustment. The two ends of the adjusting arm 22 are a second hinge structure 222 and a third hinge structure 212, respectively, which are hinged to the spring clip 23 and the clamp 21. Of course, other non-multi-segment connecting arms 22 are also within the scope of this technical solution, as long as they can achieve multi-angle and tension adjustment. The purpose is to facilitate the application of adhesive by allowing the disposable adhesive brush 24 to form different angles, thus facilitating the adhesive application process. The clamp 21, as shown... Figure 1 As shown, this solution uses two semi-circular rings connected by a fourth hinge structure 211 on the side for fastening, which facilitates the adjustment of the vertical height of the clamp 21. Of course, other types of clamps that can achieve clamping and vertical height adjustment are also within the protection scope of this technical solution.

[0032] When applying glue, the brush head of the disposable glue brush 24 contacts the surface of the object to be glued, and the path of the support rod 2 moving in the limiting groove 11 is the brush head application path. Before applying glue, since the spring clip 23, the adjusting arm 22 and the clamp 21 are all kept in a tight state, the positional relationship between the disposable glue brush 24 and the support rod 2 is kept synchronized. When the support rod 2 moves, it drives the disposable glue brush 24 to move, thereby achieving precise glue application.

[0033] Among them, the bottom of the support rod 2 is equipped with two sets of pulleys 26 through the upper and lower brackets 25 respectively. The upper and lower surfaces of the limiting groove 11 are respectively provided with sliding grooves 14 corresponding to the upper and lower sets of pulleys 26. The pulleys 26 fit against the inner wall of the sliding groove 14, driving the support rod 2 to move within the sliding groove 14. The fitting arrangement avoids deviation caused by shaking during movement.

[0034] Among them, the limiting block 3 is a long strip with a length greater than the width of the limiting groove 11, and the surface of the limiting block 3 is connected to the bottom connecting block 32 by a bolt 31.

[0035] like Figure 3 As shown, the bottom end of bolt 31 is threadedly connected to the threaded hole on the surface of connecting block 32;

[0036] Or such as Figure 4 As shown, the bottom of the bolt 31 is fixedly connected to the connecting block 32, and the top of the bolt 31 is provided with a nut for hand-tightening connection. By turning the nut, the connection, tightness adjustment and disengagement of the bolt 31 and the limit stop 3 can be realized.

[0037] The connecting block 32 is embedded in the groove 13 on the bottom surface of the base 1, and the connecting block 32 is a long strip with a length greater than the width of the limiting groove 11. The connecting block 32 fits against the inner wall of the groove 13.

[0038] The bottom surface of the base 1 is provided with a rectangular opening 15 that is consistent with the projected shape of the limiting groove 11 for the bolt 31 to pass through.

[0039] The adhesive applicator of this technical solution includes a base with a limiting groove, two limiting blocks installed in the limiting groove, a support rod slidably fitted in the limiting groove, and an adjusting arm mounted on the support rod via a clamp. The end of the adjusting arm holds a disposable adhesive brush via a spring clamp. This adhesive applicator has a simple structure, is easy to install and use, and has low manufacturing cost. The support rod slides stably within the range formed by the two limiting blocks, and the positioning of the limiting blocks is calibrated by a scale on the surface of the base. The adjusting arm is mounted on the support rod via a clamp, and the end of the adjusting arm holds a disposable adhesive brush via a spring clamp. The disposable glue brush features a tension adjustment structure in both the adjusting arm and the clamp. During glue application, the brush head of the disposable glue brush contacts the surface of the object to be glued, and the path of the support rod moving within the limiting groove is the brush head's application path. The required application length can be recorded by microscopic observation and converted into the limiting length formed by the limiting block on the limiting groove. Once the support rod slides stably within the limiting groove, the sliding path becomes the path of the brush head on the surface of the object to be glued, thus achieving precise glue application and reducing the likelihood of misalignment, missed application, glue leakage, and over-coating in localized areas.
