Description

Technical Field

[0001] This utility model relates to the field of Mylar film pasting fixtures, specifically a Mylar film pasting fixture for notebooks. Background Technology

[0002] The installation of Mylar sheets is a crucial step in the manufacturing process of laptops. As a thin sheet material with multiple functions such as insulation, shielding, and cushioning, Mylar sheets are widely used inside laptops, for example, by attaching them to the back cover, front cover, and surfaces of various electronic components, serving both protective and functional purposes.

[0003] In the early days of Mylar film installation, workers would place the components to be mounted directly on a table and apply the film. Since laptop components lacked proper fixing mechanisms, this made them prone to shifting during installation. Even slight misalignment could lead to misaligned Mylar films, affecting not only the product's appearance but also its functionality, such as poor insulation causing circuit malfunctions. To improve installation efficiency and accuracy, simple fixtures were gradually developed to assist with the installation process.

[0004] Early jigs were relatively simple in structure, mostly frames with fixed shapes and sizes. These jigs typically only assisted in positioning Mylar pieces to a certain extent, but could not be flexibly adjusted according to the shape and size of different notebook components. During the application process, the jigs had poor adaptability to Mylar pieces of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a Mylar film fixture for notebook computers, which aims to enable easy and accurate application of Mylar film.

[0006] This utility model is implemented as follows: A notebook computer Mylar film fixture includes a fixture base. Two sets of uprights are symmetrically mounted on the upper end of the fixture base. The lower ends of the uprights are fixedly connected to the fixture base, and a positioning pivot is fixedly mounted on the head of each set of uprights. A Y-axis tube is sleeved on the positioning pivot of each set of uprights. An X-axis tube is fixedly mounted on the upper end of the Y-axis tube. The two ends of the X-axis tube are rotatably mounted on the positioning pivot. A cross bracket is provided directly above the X-axis tube. The cross bracket is fixedly connected to the outer end of the positioning pivot. An elastic locking element is fixedly mounted in the Y-axis tube and frictionally locked with the positioning pivot. An elastic locking element is fixedly mounted in the X-axis tube and frictionally locked with the positioning pivot. An adjustable clamping frame is fixedly mounted on the cross bracket.

[0007] Preferably, both the first elastic locking member and the second elastic locking member include a fixed base plate, a slide rod seat, and a friction plate. The slide rod seat is slidably mounted on the fixed base plate, and the friction plate is fixedly mounted on one end of the slide rod seat.

[0008] Preferably, the fixed base plate has symmetrically arranged side ear plates on both sides, which are connected to the Y-axis tube or the X-axis tube, and the side ear plates are integrally formed with the fixed base plate.

[0009] Preferably, the slide block includes a base plate and a movable rod, the movable rod being evenly installed on one side of the base plate and fixedly connected to the base plate.

[0010] Preferably, the cross bracket includes a central support rod and side support rods, the side support rods are symmetrically installed on both sides of the central support rod, and the side support rods are fixedly connected to the central support rod.

[0011] Preferably, the adjustable clamping frame includes a crossbar section and a bending frame. The middle part of the crossbar section is fixedly installed on the side frame rod, and the bending frame is symmetrically installed at both ends of the crossbar section, and the bending frame is slidably connected to the crossbar section.

[0012] Preferably, a positioning frame for sliding installation of the side support rod is fixedly installed on the outer side of the bending frame, and a matching locking bolt is threadedly connected to the positioning frame.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application, through the setting of Y-axis and X-axis tubes, achieves multi-angle adjustment of the Mylar film in the X and Y axis directions, meeting the usage needs of Mylar film application for different laptop components and improving the flexibility and accuracy of Mylar film installation. Elastic locking components one and two can reliably lock the positioning pivot through friction, ensuring the angle is stably maintained after adjustment and preventing the position of the Mylar film from changing during installation, thus guaranteeing installation quality. The adjustable clamp frame design allows the fixture to adapt to laptop components of different sizes for Mylar film application. By sliding and bending the frame and fixing it with locking bolts, the size of the clamp frame can be easily adjusted, improving the versatility and applicability of the fixture and reducing production costs.

[0023] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0024] Reference Figure 1 , Figure 2 and Figure 3As shown, a notebook computer Mylar film fixture includes a fixture base 1. Two sets of uprights 2 are symmetrically mounted on the upper end of the fixture base 1. The lower ends of the uprights 2 are fixedly connected to the fixture base 1, and a positioning pivot 20 is fixedly mounted on the head of each set of uprights 2. A Y-axis tube 3 is sleeved on the positioning pivot 20 of the two sets of uprights 2. An X-axis tube 4 is fixedly mounted on the upper end of the Y-axis tube 3. The two ends of the X-axis tube 4 are rotatably mounted on the positioning pivot 40. A cross bracket 5 is provided directly above the X-axis tube 4. The cross bracket 5 is fixedly connected to the outer end of the positioning pivot 40. An elastic locking element 6 that frictionally locks with the positioning pivot 20 is fixedly mounted in the Y-axis tube 3. An elastic locking element 7 that frictionally locks with the positioning pivot 40 is fixedly mounted in the X-axis tube 4. An adjustable clamping frame 8 is fixedly mounted on the cross bracket 5. By incorporating a support frame 2, a Y-axis tube 3, an X-axis tube 4, a cross bracket 5, and an adjustable clamping frame 8 on the fixture base 1, the notebook component to be covered with Mylar film can be clamped and fixed in place using the adjustable clamping frame 8. Multi-angle adjustment of the notebook component in the X and Y axes is achieved through the rotational engagement of positioning pivot 20 and Y-axis tube 3, and positioning pivot 40 and X-axis tube 4, facilitating flexible Mylar film application and preventing repeated application and misalignment. Elastic locking elements 6 and 7 provide frictional locking to positioning pivots 20 and 40, ensuring stable angle maintenance and precise positioning of the Mylar film during installation. This multi-angle adjustment and stable locking function significantly improves the flexibility and accuracy of Mylar film application, adapting to different notebook models and Mylar film installation locations.

[0025] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, both the first elastic locking component 6 and the second elastic locking component 7 include a fixed base plate 61, a slide rod seat 62, and a friction plate 63. The slide rod seat 62 is slidably mounted on the fixed base plate 61, and the friction plate 63 is fixedly mounted on one end of the slide rod seat 62. The first elastic locking component 6 and the second elastic locking component 7 employ a structural design of a fixed base plate 61, a slide rod seat 62, and a friction plate 63. The slide rod seat 62 can slide on the fixed base plate 61, allowing the friction plate 63 to make close contact with the positioning shaft, generating sufficient friction to achieve locking. This structure is simple and reliable, effectively preventing the positioning shaft from rotating during use, ensuring the stability and adjustment accuracy of the fixture. The fixed base plate 61 has symmetrically arranged side ear plates 611 on both sides, which are connected to the Y-axis tube 3 or the X-axis tube 4. The side ear plates 611 are integrally formed with the fixed base plate 61. The integrally formed design of the side ear plates 611 on both sides of the fixed base plate 61 enhances the stability and strength of the connection. The side ear plate 611 provides reliable support and fixation for the fixed base plate 61, ensuring that the elastic locking element will not loosen or shift during use, thereby guaranteeing the locking effect of the elastic locking element on the positioning shaft and further improving the overall stability of the fixture. The slide block 62 includes a base plate 621 and a movable rod 622. The movable rod 622 is evenly installed on one side of the base plate 621 and is fixedly connected to the base plate 621. The structural design of the base plate 621 and the movable rod 622 of the slide block 62 allows the movable rod 622 to be evenly distributed on one side of the base plate 621, providing stable support for the friction plate 63. The evenly distributed movable rod 622 ensures uniform friction between the friction plate 63 and the positioning shaft, avoiding situations where the local friction is too large or too small, thereby improving the reliability and stability of locking. At the same time, the fixed connection between the movable rod 622 and the base plate 621 also ensures the overall structural strength of the slide block 62.

[0026] Reference Figure 2 , Figure 4 and Figure 7As shown, the cross bracket 5 includes a central support rod 51 and side support rods 52. The side support rods 52 are symmetrically installed on both sides of the central support rod 51 and are fixedly connected to the central support rod 51. The structure of the central support rod 51 and side support rods 52 of the cross bracket 5 provides a stable support platform for the adjustable clamping frame 8. The fixed connection of the central support rod 51 and side support rods 52 forms a robust frame structure that can withstand the weight of the Mylar sheet and the adjustable clamping frame 8, ensuring that no deformation or shaking occurs during installation and guaranteeing the installation accuracy of the Mylar sheet. The adjustable clamping frame 8 includes a crossbar portion 81 and a bent frame 82. The middle part of the crossbar portion 81 is fixedly installed on the side support rod 52, and the bent frame 82 is symmetrically installed at both ends of the crossbar portion 81 and is slidably connected to the crossbar portion 81. The adjustable clamping frame 8 features a crossbar section 81 and a bending frame 82 structure, with the bending frame 82 slidably connected to the crossbar section 81. This allows the adjustable clamping frame 8 to be flexibly adjusted according to the size of the Mylar film. By sliding the bending frame 82, the size of the clamping frame can be changed to accommodate notebook components of different sizes, improving the versatility and applicability of the fixture. A positioning frame 821 for sliding mounting of the side support rod 52 is fixedly installed on the outer side of the bending frame 82. A matching locking bolt 822 is threaded into the positioning frame 821. The design of the positioning frame 821 and the locking bolt 822 on the outer side of the bending frame 82 allows the bending frame 82 to be fixed to the crossbar section 81 by tightening the locking bolt 822 after the position of the bending frame 82 has been adjusted, preventing the bending frame 82 from sliding during use and ensuring the clamping effect of the clamping frame on the notebook component.

[0027] Working principle: In actual use, the size of the adjustable clamping frame 8 is adjusted according to the size of the laptop component (such as the back cover or front cover) to which the Mylar film will be applied. This ensures that the laptop component is stably clamped on both sides by the bending frames 82 on both sides. The bending frames 82 are slidable and the locking bolts 822 are tightened for fixation. Then, according to the installation position and angle requirements of the Mylar film, the angles of the Y-axis tube 3 and X-axis tube 4 are adjusted. After adjustment, the elastic locking element 6 and the elastic locking element 7 automatically lock the positioning pivot, ensuring angle stability. Finally, the Mylar film can be stably applied.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
