Description

TECHNICAL FIELD

[0001] The utility model relates to fixed frock technical field, especially in a kind of clamping fixed frock. BACKGROUND

[0002] In the existing camera module assembly process, especially after completing the assembly of lens and prism, the product needs to be moved to the glue dispensing module for glue drawing operation by handling equipment. During glue drawing process, the stable fixing of glue bucket is crucial to ensure the accuracy of glue drawing amount (for example, 16±0.8 milligrams).

[0003] In related technology, the glue bucket is clamped by a fixed ring. However, a small inner diameter of the fixed ring will make it inconvenient to put the glue bucket into the fixed ring, while a large inner diameter of the fixed ring will make it impossible to clamp the glue bucket directly and effectively. To this end, the fixed ring is designed with a deformable structure, and after the glue bucket is put in, the fixed ring is tightened by a bolt to deform and clamp the glue bucket. However, in the long run, this approach not only makes the bolt bear excessive external force, which is prone to deformation and even breakage, but also increases the risk of bolt breakage, resulting in frequent equipment downtime and component replacement. SUMMARY

[0004] The utility model aims at at least solving one of the technical problems existing in the prior art. To this end, the utility model provides a clamping fixed frock, which optimizes the stress of the tightening member when tightening the clamping ring, solves the problems of inconvenient installation and unstable fixing of the glue bucket, ensures high precision of glue drawing amount, prolongs the service life of the frock, improves operation safety and efficiency, and significantly improves the stability and productivity of the camera module assembly process.

[0005] According to the clamping fixed frock of the utility model embodiment, the utility model provides a clamping fixed frock.

[0006] The clamping ring is an open ring structure, and is used to cooperate with the workpiece and surround the outer circumferential surface of the workpiece. The clamping ring is fixedly provided with a first fixed block and a second fixed block.

[0007] The buffer block is arranged between the first fixed block and the second fixed block.

[0008] The tightening member is sequentially arranged in the first fixed block and the buffer block, and connected with the second fixed block. The tightening member tightens the distance between the first fixed block and the second fixed block, and makes the clamping ring clamp the workpiece. After the workpiece is clamped, the two side end faces of the buffer block are respectively abutted and fixed with the first fixed block and the second fixed block.

[0009] According to an embodiment of this utility model, a clamping and fixing fixture has at least the following beneficial effects: The clamping ring adopts an open-loop structure. This design not only flexibly adapts to glue buckets of different sizes, ensuring quick and accurate installation, but also avoids clamping inconvenience or ineffectiveness due to unsuitable inner diameters. Furthermore, a buffer block is added between the first and second fixing blocks fixed on the clamping ring. This design cleverly disperses the pressure generated when the tightening component is tightened, preventing the clamping ring and its related components from deforming or being damaged due to excessive force. In addition, after the glue bucket is clamped, the two end faces of the buffer block press against and fix the first and second fixing blocks respectively, ensuring the stability of the entire structure and effectively preventing the tightening component from loosening or slipping. This design further improves clamping effectiveness and reliability. In application, the tightening component passes sequentially through the first fixed block and the buffer block, and connects to the second fixed block. By tightening the gap between the first and second fixed blocks, the clamping ring is effectively tightened and the glue bucket is securely clamped, significantly enhancing mechanical strength and reducing the risk of deformation and breakage of the tightening component due to long-term use or improper operation. Overall, this design not only solves the problem of unstable glue bucket fixation in existing technologies, but also significantly enhances the durability and safety of the system through optimized structural design and material selection. This not only reduces equipment failure rate and maintenance costs, but also improves production efficiency and product quality, providing a more efficient and reliable technical solution for the camera module assembly industry.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] In existing camera module assembly processes, especially after the lens and prism assembly is completed, the product needs to be moved to the dispensing module for glue application using handling equipment. During the glue application process, the stable fixation of the glue container is crucial to ensuring the accuracy of the glue application amount (e.g., 16 ± 0.8 mg).

[0034] In related technologies, glue buckets are clamped using retaining rings. However, a small inner diameter of the retaining ring makes it inconvenient to insert the glue bucket, while a large inner diameter makes it impossible to directly and effectively clamp the glue bucket. To address this, a deformable structure is used for the retaining ring. After the glue bucket is inserted, bolts are tightened to deform the retaining ring and clamp the glue bucket. However, over time, this method not only subjectes the bolts to excessive external force, making them prone to deformation or even breakage, but also increases the risk of bolt breakage, leading to frequent equipment downtime and component replacements.

[0035] Therefore, such asFigure 1 and Figure 2 As shown, this utility model proposes a clamping and fixing fixture, including a clamping ring 100, a first fixing block 110, a second fixing block 120, a buffer block 200, and a tightening member 300. The first fixing block 110 and the second fixing block 120 are both fixedly disposed on the clamping ring 100. The buffer ring is disposed between the first fixing block 110 and the second fixing block 120. The tightening member 300 is used to retract the clamping ring 100. Specifically, the clamping ring 100 has an open-loop structure and can deform under external force. In some applications, the clamping ring 100 is made of thin steel, aluminum, or plastic. In application, the clamping ring 100 is used to fit around the outer circumference of the workpiece. The tightening member 300 passes sequentially through the first fixing block 110 and the buffer block 200, and is connected to the second fixing block 120. The tightening member 300 tightens the gap between the first fixing block 110 and the second fixing block 120, thus clamping the workpiece. After the workpiece is clamped, the two end faces of the buffer block 200 press against and fix the first fixing block 110 and the second fixing block 120 respectively. It should be noted that, taking a glue bucket as an example, an open-loop clamping ring 100 is used. This design not only flexibly adapts to glue buckets of different sizes, ensuring quick and accurate installation, but also avoids clamping inconvenience or ineffectiveness due to unsuitable inner diameter. Furthermore, a buffer block 200 is added between the first fixing block 110 and the second fixing block 120 fixedly disposed on the clamping ring 100. This design cleverly disperses the pressure generated when the tightening member 300 tightens, preventing the clamping ring 100 and its related components from deforming or being damaged due to excessive force. In addition, after the rubber bucket is clamped, the two end faces of the buffer block 200 press against and fix the first fixing block 110 and the second fixing block 120 respectively, ensuring the stability of the entire structure and effectively preventing the tightening member 300 from loosening or slipping, further improving the clamping effect and reliability. In some embodiments, the tightening member 300 is threadedly connected to the second fixing block 120, for example, the tightening member 300 is a screw. In application, the tightening member 300 is along a first direction, such as... Figure 2 The XR axis shown rotates to tighten the gap between the first fixing block 110 and the second fixing block 120. Furthermore, the tightening component 300 can utilize larger-gauge and higher-strength fatigue-resistant screws, such as M4 screws of grade 12.9, significantly enhancing mechanical strength and reducing the risk of deformation and breakage of the tightening component 300 due to long-term use or improper operation. Overall, this not only solves the problem of unstable glue bucket fixing in existing technologies but also significantly enhances the durability and safety of the system through optimized structural design and material selection. This not only reduces equipment failure rates and maintenance costs but also improves production efficiency and product quality, providing a more efficient and reliable technical solution for the camera module assembly industry.

[0036] In some embodiments, the clamping ring is square or polygonal (not shown in the figure) to accommodate workpieces of various shapes. See also... Figure 1 The clamping ring 100 is circular, adaptable to cylindrical workpieces. This circular design allows for flexible handling of various cylindrical workpieces, enhancing the tooling's versatility and adaptability, thereby improving production efficiency. It should be noted that glue buckets are generally cylindrical. This design choice not only ensures that the clamping ring 100 perfectly fits the outer circumference of the glue bucket, providing a uniform clamping force distribution, but also simplifies the adaptation process between the tooling and glue buckets of different sizes and shapes. Further reference... Figure 2 An opening 101 is provided on one side of the clamping ring 100, and the first fixing block 110 and the second fixing block 120 are both located on the side of the clamping ring 100 facing the opening 101. It is easy to understand that the initial deformed end of the clamping ring 100 under force is located on the side of the opening 101. The arrangement of the first fixing block 110 and the second fixing block 120 on the side of the opening 101 ensures that the force exerted by the tightening member 300 when tightening can directly act on the key parts of the clamping ring 100, maximizing the contraction and deformation of the clamping ring 100, improving the clamping effect, and reducing operational uncertainties. Optionally, the first fixing block 110 and the second fixing block 120 are arranged in parallel, ensuring that when the tightening member 300 tightens the first fixing block 110 and the second fixing block 120, the pressure on both sides of the clamping ring 100 is uniform and symmetrical, avoiding deformation or damage caused by excessive force on one side. Furthermore, the parallel arrangement of the first fixing block 110 and the second fixing block 120 helps maintain the overall stability of the clamping ring 100, ensuring that it will not skew or loosen due to uneven force during long-term use, thereby extending the service life of the tooling. In some embodiments of this utility model, the clamping ring 100, the first fixing block 110, and the second fixing block 120 are integrally connected, which not only enhances the mechanical strength of the entire structure and reduces the number of connection points between components, reducing the risk caused by loosening or breakage at the connection points, but also simplifies the manufacturing process and reduces production costs. In addition, the integrally molded structure is more convenient in terms of assembly and maintenance, which helps to improve the operating efficiency on the production line. Optionally, the buffer block 200 is made of deformable materials such as rubber or silicone. In some embodiments of this utility model, the buffer block 200 is made of polyurethane. Polyurethane material has excellent elasticity and wear resistance, which can effectively absorb and disperse pressure during the tightening process of the tightening member 300, preventing the clamping ring 100 and other components from being damaged due to excessive force. Furthermore, polyurethane also possesses excellent chemical corrosion resistance and anti-aging properties, making it suitable for long-term use in industrial environments, further ensuring the durability and reliability of tooling.

[0037] Refer to Figure 1 and Figure 2In some embodiments of this utility model, the clamping ring 100 is provided with a thickness member 400, which is located on the inner wall of the clamping ring 100 and is used to abut against the outer surface of the workpiece. On the one hand, the thickness member 400 can further reduce the effective inner diameter of the clamping ring 100 in clamping the workpiece, allowing the clamping ring 100 to adapt to workpieces with smaller outer diameters. When processing workpieces of different diameters, a more precise fit can be achieved by adjusting the thickness member 400, improving the applicability of the clamping ring 100. On the other hand, the presence of the thickness member 400 can also protect the surface of the workpiece, increasing the contact area between the clamping ring 100 and the workpiece, ensuring a more stable clamping effect, especially avoiding scratches or wear caused by direct contact with metal parts. For example, the thickness member 400 is made of a similar material to the buffer block 200, which is made of rubber, silicone, or polyurethane. In some embodiments of this utility model, the thickness member 400 is detachably disposed on the clamping ring 100. For example, high-quality anti-abrasion tape from brands such as 3M is selected, which not only provides excellent wear-resistant protection but also enhances the friction between the clamping ring 100 and the workpiece, ensuring a more stable clamping effect. Furthermore, the adhesion and connection method of the anti-abrasion tape is simple and reliable, easy to install and replace, and requires no additional tools or equipment, greatly improving operational convenience. In some embodiments, the thickness member is arranged at a single point, multiple points, or multiple segments on the inner wall of the clamping ring (not shown in the figure). Referring again to some embodiments of this utility model... Figure 1 and Figure 2 The thickness element 400 is arranged around the inner peripheral wall of the clamping ring 100, and can evenly cover the thickness element 400 on the entire inner wall of the clamping ring 100, thereby providing a consistent clamping force and protection for the glue bucket throughout the entire circumference, avoiding uneven local force, and further improving the overall performance and reliability of the clamping and fixing fixture.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
