Description

Technical Field

[0001] The invention relates to an installation device and an installation method, in particular to a flashlight cover installation device and an installation method with a double-layer suction head structure, belonging to the technical field of mobile phone flashlight cover installation. Background Art

[0002] With the rapid development of the mobile phone manufacturing industry, the requirements for production efficiency and product quality are increasing day by day. In the process of mobile phone assembly, the installation of the flash cover is indeed an important and delicate link.

[0003] On the one hand, although the flash cover is small, its installation accuracy directly affects the overall aesthetics of the phone's appearance. If the installation position is inaccurate, the angle is biased, or the fit is not tight, it may cause defects in the appearance of the phone, affecting consumers' willingness to buy. Moreover, in today's highly competitive mobile phone market, the perfection of appearance is often one of the important considerations for consumers when choosing a mobile phone.

[0004] On the other hand, the installation quality of the flash cover is also related to the functional performance of the mobile phone. An accurately installed flash cover can ensure that the light of the flash is evenly emitted, improving the effect of taking photos and videos. If it is not installed properly, it may cause uneven light scattering, affecting the quality of the mobile phone's photos and reducing the user experience.

[0005] In order to meet the high requirements of the mobile phone manufacturing industry for production efficiency and product quality, advanced installation equipment and technology are needed in the flash cover installation process. For example, the use of high-precision mechanical installation equipment can achieve fast and accurate installation, improve production efficiency and ensure the stability of installation quality. At the same time, for some special models or customized mobile phones, the flexibility of manual installation can also be combined to ensure that each flash cover can be perfectly installed.

[0006] 1. In the prior art, the mobile phone flash lamp cover installation equipment generally uses a single-layer suction head to absorb the lamp cover. However, due to various factors in the production process (such as the type of glue, coating amount, ambient temperature, etc.), a strong adhesion force is often formed between the paper and the lamp cover. The traditional single-layer suction head design cannot simultaneously achieve the functions of stable pressing and precise suction when dealing with lamp covers with strong adhesion, resulting in the lamp cover being difficult to smoothly detach from the paper during the suction process. This not only increases the complexity of equipment operation, but also significantly reduces installation efficiency, and may even damage the lamp cover or paper, affecting the stability of the overall production line and product quality; 2. In the prior art, traditional installation tools are usually designed for flash covers of specific shapes and sizes. Different installation tools are often required for flash covers of different specifications, and the versatility is poor. When faced with flash covers of various shapes and sizes, it may be necessary to prepare multiple installation tools, which increases the cost and operation complexity. During operation, the traditional installation method may cause scratches, squeezing and other damages to the flash cover due to improper force or inappropriate tools.

If the shape of the adsorption position is an arc, the adjusting knob 238 is rotated to drive the adjusting screw 229 to rotate, and the adjusting screw 229 rotates to drive the lifting foot 226, the outer connecting tube 211 and the outer suction head 212 to move up and down, and the outer suction head 212 and the inner suction head 216 are adjusted to fit tightly with the adsorption position at the same time.

[0046] Embodiment 4: During a shooting assignment in a professional photography studio, the photographer needs to install flash covers of different specifications to meet specific shooting needs.

[0047] The studio introduced the flashlight cover installation device with a double-layer suction head structure of the present invention. First, according to the size specifications of the flashlight cover to be installed, the staff selected a suitable model from the spare external suction head 212, and installed the external suction head 212 on the bottom of the inner wall of the external connection tube 211 through threaded connection. At the same time, a suitable internal suction head 216 was selected and installed on the bottom of the inner wall of the internal connection tube 215; When preparing to install a flashlight cover with an arc surface, the staff rotates the adjustment knob 238 to drive the adjustment screw 229 to rotate. The rotation of the adjustment screw 229 causes the lifting foot 226, the outer connecting tube 211 and the outer suction head 212 to move up and down. After fine adjustment, the outer suction head 212 and the inner suction head 216 are tightly fitted with the arc-shaped adsorption position of the flashlight cover at the same time. During the fitting process, the first sealing ring 235 ensures the sealing between the outer suction head 212 and the annular limiting plate 213, and the second sealing ring 237 ensures the sealing between the inner suction head 216 and the inner connecting tube 215 to prevent air leakage; When the outer suction head 212 and the inner suction head 216 are tightly fitted with the adsorption position of the flashlight cover to be installed, the staff presses the start button on the control panel 233, and the controller 232 starts the micro vacuum pump 221 to work. The micro vacuum pump 221 evacuates the inside of the outer connecting tube 211 and the inner connecting tube 215 through the main suction pipe 222, the first suction hose 223 and the second suction hose 224, so that the outer suction head 212 and the inner suction head 216 can firmly adsorb the adsorption position of the flashlight cover to be installed at the same time. In this process, the sealing ring 241 further enhances the sealing performance between the outer connecting tube 211 and the inner connecting tube 215. After being firmly adsorbed, the staff holds the anti-slip cover 244 on the grip 231, moves the flash cover to be installed steadily to the flash position, and installs it accurately. During the installation process, due to the stability and accuracy of the equipment, the flash cover can be quickly and accurately installed in place; After completing the installation of one flashlight cover, the staff needs to install another flashlight cover of a flat shape. First, adjust the bottom of the outer suction head 212 and the inner suction head 216 to the same horizontal plane to meet the needs of the flat suction position, and then follow the same steps to successfully complete the installation of the flat flashlight cover. After the installation is completed, the staff turns off the micro vacuum pump 221, releases the adsorption force between the outer suction head 212 and the inner suction head 216 and the flash cover, and removes the installation equipment. The entire installation process is efficient and accurate, which greatly improves the work efficiency of the photography studio, while also protecting the flash cover and extending its service life.
