Description

Technical Field

[0001] The invention relates to the field of functional film installation, and in particular to a side window functional film installation device. Background Art

[0002] As a new type of intelligent material, functional film has multiple functional properties, such as dimming, heat insulation, UV protection, explosion-proof, conductive and sound insulation, etc. It has been widely used in architectural glass, automotive glass, electronic display screens and decorative materials. Functional film usually adopts a multi-layer composite structure, and dynamically switches functions by adjusting electric fields, light or other physical parameters to meet the application needs of different scenarios.

[0003] In the application scenario of vehicle side windows, the installation of functional films can effectively improve the quality of the interior environment. For example, heat insulation functional films can reduce the transfer of solar radiation heat and improve the efficiency of air conditioning in the car; UV protection functional films can protect passengers from UV damage and delay the aging of interior materials; and membranes with sound insulation functions can significantly reduce noise outside the car and improve driving comfort. As people's requirements for vehicle comfort, privacy and safety continue to increase, the demand for the application of functional films on car side windows continues to grow.

[0004] However, vehicle side windows usually have certain curvature or tilt characteristics, and the functional film itself is soft and thin, which is easily affected by the external environment (such as wind and static electricity) during installation, making it difficult to ensure the flatness and adhesion quality of the film during positioning and lamination. The traditional manual operation method has the following problems during the installation of functional films:

[0005] Since the functional film is thin, it is easily affected by environmental wind or static electricity, and it is difficult to ensure the flatness and accuracy of the film during manual positioning;

[0006] During the film application process, due to the unevenness of manual scraping techniques, bubbles are easily left between the film and the window surface, resulting in damage to the functional film.

[0007] Manual film pasting is slow and requires high experience from technicians, which is not conducive to large-scale and efficient construction;

[0008] In the existing manual installation process, it is difficult to achieve a smooth and gradual fit of the functional film from the center to the edge, and the film is prone to partial warping or unevenness. Summary of the invention

DETAILED DESCRIPTION

[0042] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0043] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0044] like Figure 1 and Figure 2 As shown, a side window functional film installation device of the present invention comprises a positioning installation tube 8, wherein the positioning installation tube 8 has an installation cavity 27, and the bottom surface of the positioning installation hole in contact with the functional film 2 is a negative pressure adsorption surface 26. When installing, first find the central adsorption position of the functional film 2, and then fit the adsorption surface of the positioning installation tube 8 to the adsorption position to achieve negative pressure adsorption, thereby locating the central area;

[0045] Please continue reading Figure 1 and Figure 2 , and further comprises four telescopic clamping arms 100, one end of each telescopic clamping arm 100 is connected to the positioning and installing cylinder 8 through an elastic hinge mechanism 14, and a clamping mechanism 15 is arranged at the other end thereof, and the four corners of the functional film 2 are clamped by the clamping mechanisms 15 of at least four telescopic clamping arms 100, and the two ends of the clamped functional film 2 are tilted relative to the negative pressure adsorption surface 26, and form an angle a with the window surface 3 to be bonded, and after the four corners of the functional film 2 are clamped, the four corners of the functional film 2 are stretched, and the center position is negatively adsorbed, so as to tension the whole functional film 2, and because the four corners of the functional film 2 are tilted, when the functional film 2 contacts the window surface 3, only the center adsorption position contacts and adsorbs, and the rest of the functional film 2 is in a non-contact state, so that positioning can be performed by only aligning the center adsorption position of the functional film 2 with the center position of the window surface 3, and when installing the functional film 2, the functional film 2 needs to be tensioned;

[0046] like Figure 2 and Figure 3 As shown, two elastic scrapers 9 are also included, which are located on both sides of the positioning and mounting cylinder 8, and the elastic scrapers 9 are located between the functional film 2 and the telescopic clamping arm 100. Each elastic scraper 9 is connected to the positioning and mounting cylinder 8 through a telescopic ejection mechanism 23, and each elastic scraper 9 is wrapped and installed in an annular storage cavity 16 opened at the bottom of the positioning cylinder in an arc-shaped contracted shape when not in use. Once used, the elastic scraper 9 can be rotated and expanded in an arc shape to achieve rotary scraping of the central area to both sides, thereby achieving a close fit at the center position;

[0047] It also includes an extrusion drive mechanism, which is installed in the positioning installation cylinder 8 and is conductively connected to the telescopic ejection mechanism 23. When the functional film 2 and the center position of the window surface 3 are positioned, the extrusion drive mechanism can be driven by extrusion, so that the telescopic ejection mechanism 23 is extended after air intake, and then the elastic scraper 9 is driven to move from the middle to the two sides, so as to achieve the purpose of paving the functional film 2 from the center to the two sides;

[0048] When the functional film 2 is being installed, the elastic scraper blade 9 is elastically unfolded from an arc-shaped contracted state until it is guided and contacted with the inner side surface of the window frame 10. The unfolded elastic scraper blade 9 is driven by an extrusion drive mechanism to move along the length direction of the functional film 2 to fit the functional film 2 to the window surface 3. In order to increase the contact stability with the window frame 10, guide wheels 11 can be installed on the two side end surfaces of the elastic scraper blade 9. The protruding guide wheels 11 are used to guide the contact with the window frame 10, so that the elastic scraper blade 9 can be guided and moved along the functional film 2 to achieve the purpose of scraping the film.

[0049] like Figure 1 As shown, a magnetic layer 28 is provided on the upper end surface of the elastic scraper 9, and a plurality of magnetic blocks are arranged on the bottom surface of the telescopic clamping arm 100 opposite to the magnetic layer 28 along the length direction of the telescopic clamping arm 100. When the elastic scraper 9 is driven by the extrusion drive mechanism, the elastic scraper 9 attracts the magnetic blocks on the top and continuously reduces the angle a. When the elastic scraper 9 continuously moves along the two ends of the functional film 2, the telescopic clamping arm 100 is attracted by magnetic force, so that the telescopic clamping arm 100 continuously descends and the functional film 2 at the bottom continuously fits the window surface 3, and the angle a gradually decreases.

[0050] In this embodiment, a flexible contact layer is provided at the bottom of the elastic scraper 9, and the flexible contact layer can be made of cloth or other materials, and should be smooth and non-sticky when in contact with the functional film 2; in order to enable the elastic scraper 9 to always adsorb the telescopic clamping arm 100 at the top and prevent the magnetic attraction force from being affected by the long distance, in this embodiment, the magnetic force of the magnetic attraction block is the smallest on the side away from the negative pressure adsorption surface 26, and gradually increases as it moves away from the negative pressure adsorption surface 26.

[0051] like Figure 2 and Figure 3As shown, the outer surface of the positioning and mounting cylinder 8 is provided with an annular mounting cavity 727 near the upper end of the annular receiving cavity 16, and each telescopic clamping arm 100 is installed in the annular mounting cavity 727 through the elastic hinge mechanism 14, and the elastic hinge mechanism 14 includes a fixed screw 143 fixed in the annular mounting cavity 727, and a rotating shaft sleeve 142 is installed on the fixed screw 143. An articulated bracket 146 is provided at one end of the rotating shaft sleeve 142, and the telescopic clamping arm 100 is connected to the articulated bracket through a hinge rod 145 and a torsion spring 24. 146 is elastically hinged, and a locking nut 141 is installed on the top of the fixed screw 143, and the rotating shaft sleeve 142 is locked by the locking nut 141. When clamping the functional membrane 2, the length of each telescopic clamping arm 100 is adjusted according to the shape and size of the functional membrane 2, and then the rotation angle of the telescopic clamping arm 100 is adjusted. When adjusting, just loosen the locking nut 141. Since a torsion spring 24 is provided, the telescopic clamping arm 100 always remains in a tilted state under the action of the torsion spring 24, so that the functional membrane 2 can be tilted at both ends after clamping without contacting the window surface 3.

[0052] like Figure 2 As shown, each telescopic clamping arm 100 includes a telescopic sleeve 5, a first telescopic rod 6 and a second telescopic rod 4, the telescopic sleeve 5 has a telescopic installation cavity 5127, one end of the first telescopic rod 6 and the second telescopic rod 4 are both telescopically plugged in the telescopic installation cavity 5127, and a locking screw is provided on both sides of the telescopic sleeve 5 corresponding to the positions of the first telescopic rod 6 and the second telescopic rod 4, and the positions of the first telescopic rod 6 and the second telescopic rod 4 in the telescopic sleeve 5 are positioned by the locking screws, and the clamping mechanism 15 is arranged on the second telescopic rod 4, and the relative stretching between the telescopic rods and the positioning after stretching are achieved by the locking screws.

[0053] like Figure 3 As shown, a metal suction block is embedded in the inner side surfaces of both ends of the elastic scraper 9, and an electromagnet 17 is set at the positions corresponding to the metal suction blocks on both sides of the annular storage cavity 16. When the elastic scraper 9 is not in use, the elastic scraper 9 is magnetically attracted to the electromagnet 17 through the metal suction block. When the electromagnet 17 is energized, the electromagnet 17 is used to always attract the metal suction block of the elastic scraper 9. At this time, the elastic scraper 9 is in an elastically deformed state. After the power supply of the electromagnet 17 is disconnected, the elastic scraper 9 elastically opens to achieve rotary scraping in an arc state. In this embodiment, the elastic scraper 9 can be made of memory metal material.

[0054] like Figure 4 and Figure 6As shown, the extrusion drive mechanism includes an extrusion cylinder 1, an elastic air storage bag 20 is installed at the inner end of the extrusion cylinder 1, the extrusion cylinder 1 is movably installed in the positioning mounting cylinder 8 and extends out of the positioning mounting cylinder 8, and the elastic air storage bag 20 and the telescopic ejection mechanism 23 are connected and communicated through an air guide tube 22.

[0055] The telescopic ejection mechanism 23 is composed of a plurality of telescopic sleeves 5 with different outer diameters, and the telescopic ejection mechanism 23 is installed in the installation groove 19 opened on the inner bottom surface of the positioning installation cylinder 8. One end of the telescopic ejection mechanism 23 is fixedly connected to the inner wall surface of the installation groove 19, and the other end thereof passes through the positioning installation cylinder 8 and is fixedly connected to the center position of the elastic scraper 9. The elastic air storage bag 20 is connected to the telescopic sleeve 5 with the largest outer diameter through the air guide tube 22. By squeezing the elastic air storage bag 20, the gas in the elastic air storage bag 20 enters into each telescopic sleeve 5 through the air guide tube 22, and the elastic scraper 9 is ejected by using the gas to drive the stretching between the telescopic sleeves 5;

[0056] A spring 24 is also installed on the outside of the telescopic ejection mechanism 23, one end of the spring 24 is fixedly connected to the inner side of the elastic scraper 9, and the other end of the spring 24 is fixedly connected to the end face of the telescopic sleeve 5 with the largest outer diameter. When the telescopic ejection mechanism 23 is stretched due to the filling of gas, the spring 24 will also be stretched. Once the squeezing of the elastic air storage bag 20 is removed, the spring 24 can be used to reset the telescopic ejection mechanism 23. In this embodiment, the telescopic ejection mechanism 23 is similar to the telescopic antenna structure in the prior art, except that it is necessary to ensure the sealing of the contact between the inner and outer ends of each telescopic sleeve 5. Therefore, when each telescopic sleeve 5 is fitted on each other, an annular sealing piston ring can be set at the contact surface position, so as to achieve the sealed fitting of adjacent telescopic sleeves 5. After the telescopic ejection mechanism 23 is filled with gas, the gas can be used to stretch the entire telescopic ejection mechanism 23 to achieve the purpose of ejecting the elastic scraper 9.

[0057] In order to facilitate operation, in this embodiment, a gripping operation portion 12 is fixedly installed on the outside of the positioning installation tube 8;

[0058] like Figure 7 As shown, the clamping mechanism 15 includes an elastic clamping piece 41, one end of the elastic clamping piece 41 is fixedly connected to the telescopic clamping arm 100, and the other end of the elastic clamping piece 41 is a snap-in end 42. Positioning pins 43 are also provided on both sides of the bottom of the elastic clamping piece 41. When clamping the functional film 2, a clamping protrusion is formed at the clamping position of the functional film 2. The clamping protrusion is inserted into the elastic clamping piece 41 and positioned by the positioning pin 43. The clamping protrusion can be manually cut off by a tool after the film is pasted. During installation, the positioning pin 43 passes through the clamping protrusion to complete the positioning and clamping.

[0059] like Figure 4-Figure 6 As shown, a plurality of negative pressure suction holes 25 are provided on the negative pressure adsorption surface 26, a negative pressure pump 21 is installed in the installation cavity 27 of the positioning installation tube 8, the suction end of the negative pressure pump 21 is connected and conducted with each negative pressure suction hole 25, a control main board is embedded in the top of the extrusion drive mechanism, a control button 13 is also provided corresponding to the upper end surface of the control main board, the control main board is connected to the electromagnet 17 and the negative pressure pump 21, the switch is controlled by the control button 13, a rechargeable battery is also installed on one side of the negative pressure pump 21, the negative pressure pump 21 and the battery iron are powered by the rechargeable battery, and a support partition 18 is provided on the top of the negative pressure pump 21.

[0060] The present invention provides a side window functional film 2 installation device, which uses a negative pressure adsorption surface 26 as an adsorption action point to make the central area of ​​the functional film 2 contact and support the window surface 3 first, and uses four telescopic clamping arms 100 to clamp the four corners of the functional film 2, so that the non-central area of ​​the functional film 2 is tilted, avoiding direct contact with the window surface 3 in the initial stage of film application, thereby effectively reducing the possibility of bubble generation, so that the functional film 2 can be straightened and laid flat during film application, which is convenient for operation;

[0061] The elastic scraper 9 in the device of the present invention is in an arc-shaped contracted state when not in use, and is opened in an arc-shaped state when the film is installed. The elastic scraper 9 opened in an arc-shaped state is used to perform a rotary scraping on the center position of the functional film 2, firstly to fit the center position, and then the elastic scraper 9 is driven by the extrusion drive mechanism to move along the length direction of the functional film 2, gradually scraping the functional film 2 from the center to both sides, so that it can fit the window surface 3 stably;

[0062] The elastic scraper blade 9 and the telescopic clamping arm 100 are attracted by magnetic force, and the telescopic clamping arm 100 is gradually driven down while the scraper blade moves, so that the functional film 2 is gradually attached from the center to the edge, further improving the flatness and quality of the film.

[0063] The device replaces manual installation with automated operation, solving the problems of residual bubbles and warping caused by inaccurate positioning and uneven scraping in the traditional manual film pasting process, while greatly improving work efficiency.

[0064] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
