Description

[Technical field]

[0001] The utility model relates to the technical field of film pasting, in particular to a film pasting tool and a film pasting component. [Background technology]

[0002] The film can effectively prevent the screen of electronic devices from being scratched or broken, but in the process of film application, operational errors are often encountered, such as the appearance of bubbles, etc., which require the protective film to be removed and re-applied. During the repeated application process, the protective film will lose its stickiness and become scrapped.

[0003] For this reason, electronic device film applicators came into being. However, the existing film applicator structure has usage defects, and a large number of bubbles are generated during the film application process. In order to eliminate the bubbles, many film applicator tools will introduce a pressing tool with an exhaust function. However, when pressing and scraping the mobile phone screen with many existing pressing tools, the operation is either stuck and not smooth, resulting in uneven force on the electronic device and the protective film during the film application operation, and the exhaust process is dry and difficult to move, or the pressing tool is not in sufficient contact with the screen of the electronic device during the scraping operation, and the bubbles cannot be discharged.

[0046] Please combine Figure 1 - Figure 3 The first embodiment of the utility model provides a film pasting tool 1, comprising a main body 11 and a pressing assembly 14 detachably connected to the main body 11, one side of the main body 11 is provided with a receiving cavity 12, the receiving cavity 12 is used to place the device to be pasted, the main body 11 also includes a frame 13 located at two opposite sides of the receiving cavity 12, the frame 13 is provided with a slide rail 131, and the frame 13 is provided with a track 132 on the inner wall of the receiving cavity 12;

[0047] The pressing assembly 14 includes a detachably connected pressing bracket 141 and a pressing piece 142. The pressing bracket 141 is slidably connected to the slide rail 131. A top step 15 is provided on the inner wall of the main body 11 close to the frame 13. When the pressing assembly 14 is connected to the main body 11 and slides, the pressing piece 142 moves from abutting the top step 15 to abutting the rail 132 and moves along the length direction of the rail 132.

[0048] Specifically, see Figure 2 , the pressing bracket 141 is slidably connected with the slide rail 131, and a concave through groove 1412 for accommodating the slide rail 131 is provided on the pressing bracket 141. In the present embodiment, the slide rail 131 is in the shape of a smooth long cylinder, and the pressing bracket 141 is correspondingly provided with a concave through groove 1412 for accommodating the cylindrical slide rail 131. The concave through groove 1412 is partially movably mounted on the slide rail 131 to realize the sliding connection between the pressing bracket 141 and the slide rail 131. The smooth cylindrical surface ensures that the inner wall of the pressing bracket 141 is in full contact with the slide rail 131, thereby providing a smoother sliding of the pressing component 14 on the slide rail 131.

[0049] Furthermore, two top steps 15 are provided near the inner walls of the frame 13 on both sides.

[0050] Furthermore, a cavity 1411 for accommodating the pressing member 142 is disposed in the pressing bracket 141 .

[0051] Optionally, the shape of the slide rail 131 can match the side shape of the electronic device placed in the accommodating cavity 12, and can be in the form of a straight line, an arc, or a complex curve, so as to apply film to electronic devices of different models.

[0052] It can be understood that the top step 15 is used for positioning the initial position. When the pressing assembly 14 is connected to the main body 11 and slides, the pressing member 142 can start sliding from the top step 15 and then move along the length direction of the slide rail 131; the shape and size of the accommodating cavity 12 can accommodate the device to be film-sticked and provide sufficient support.

[0053] For further information, see Figure 3 The top step 15 includes a top surface 151, and the top surface 151 is at a height H (eg, Figure 3 H) is higher than the height h of the track 132 relative to the accommodating cavity 12 (such as Figure 3 h) in.

[0054] Specifically, the frame 13 surrounds the accommodating cavity 12, and the accommodating cavity 12 is recessed relative to the top step 15 toward the side away from the frame 13, and the top surface 151 is relative to the height H of the accommodating cavity 12 (such as Figure 3 H) is higher than the height h of the track 132 relative to the accommodating cavity 12 (such as Figure 3 h), that is, the height H of the top surface 151 of the top step 15 (such as Figure 3 The H) in the figure is higher than the accommodating cavity 12 and higher than the track 132, the top surface 151 is higher than the track 132, and the pressing member 142 is inclined relative to the screen of the electronic device, so that the film-sticking process has directionality, and when the roller 1421 abuts against the protective film, it is easier to expel the gas and prevent the generation of bubbles.

[0055] Furthermore, the top step 15 further includes an inclined surface 152 , and the pressing member 142 abuts against the rail 132 along the inclined surface 152 from the top surface 151 .

[0056] It can be understood that the angle of the slope 152 needs to balance the requirements of speed and stability. The length of the slope 152 affects the sliding distance of the pressing member 142 from the top step 15 to the track 132. Therefore, the slope 152 should ensure that it is steep enough while providing a sufficiently long sliding distance to help the pressing component to have a stable structure and smooth sliding during the sliding process.

[0057] Specifically, the inclined surface 152 , the track 132 and the slide rail 131 are constructed using materials with a low friction coefficient to reduce friction and improve the sliding effect.

[0058] For further information, see Figure 5 The pressing bracket 141 is provided with an avoidance notch for avoiding the top step 15 , and the avoidance notch helps the pressing member 142 to abut against the top surface 151 of the top step 15 more firmly.

[0059] Specifically, in this embodiment, the specific shape of the top step 15 is not limited, as long as the top surface 151 can support the pressing member 142 and the inclined surface 152 can make the pressing member 142 slide smoothly and steadily.

[0060] Furthermore, the track 132 is inclined from an end close to the top step 15 to an end away from the top step 15 .

[0061] Specifically, please participate Figure 4 The track 132 adopts a sloped track design. There is a slope 1321 on the track 132 with the same inclination angle as the inclined surface 152. The position of the slope 1321 on the track 132 corresponds to the position of the inclined surface 152 on the top step 15. The inclined surface 152 cooperates with the slope 1321 on the track 132 to prevent the pressing piece 142 from sliding and getting stuck on the track 132.

[0062] Furthermore, the position of the slope 1321 of the track 132 and the position of the inclined surface 152 on the top step 15 are consistent with the structure of the accommodating cavity 12 , and the stop end of the inclined surface 152 is defined by the starting end of the accommodating cavity 12 .

[0063] Furthermore, the pressing member 142 includes a roller 1421 and bosses 1422 protruding from both ends of the roller 1421 , and the bosses 1422 abut against the top step 15 or the track 132 .

[0064] Specifically, the boss 1422 abuts against the top step 15 or the track 132 to provide a more stable support. Furthermore, the boss 1422 serves as a contact point between the pressing bracket 141 and the pressing member 142, and its edge shape is set to a smooth arc to provide proper lubrication and prevent scratching of the protective film, reduce friction, and improve the sliding effect. The roller 1421 is a cylindrical roller 1421 made of silicone, which can provide a better buffering effect and press the electronic screen back and forth.

[0065] Furthermore, the slide rail 131 is arranged along the length direction of the accommodating cavity 12 , the roller 1421 is perpendicular to the slide rail 131 , and the length of the roller 1421 is not less than the width of the accommodating cavity 12 .

[0066] Specifically, the roller 1421 and the boss 1422 on the pressing member 142 are also detachably connected.

[0067] It can be understood that the roller 1421 is firmly fixed on the pressing bracket 141, and the pressing bracket 141 drives the roller 1421 to roll stably along the length direction of the slide rail 131 through the cooperation between the slide rail 131 and the track 132. The length of the roller 1421 is not less than the width of the accommodating cavity 12 and fully covers the accommodating cavity 12 when rolling. The roller 1421 can scrape and press the entire protective film to completely remove bubbles, so that the entire protective film is completely attached to the screen of the electronic device, thereby improving the film sticking effect.

[0068] Furthermore, a mounting notch 1311 is provided at one end of the slide rail 131 close to the top step 15 , and the pressing assembly 14 can be installed on the main body 11 through the mounting notch 1311 and be slidably connected to the slide rail 131 .

[0069] It can be understood that the connection between the pressing component 14 and the slide rail 131 needs to have sufficient stability and detachability. In this embodiment, the installation notch 1311 serves as an installation guide, and the pressing component 14 can be snapped into the installation notch 1311 and abut against the rail 132.

[0070] Specifically, the buckle connection method ensures that the pressing assembly 14 is firmly connected to the slide rail 131 while facilitating disassembly, maintenance or replacement.

[0071] Furthermore, a positioning column 111 is provided at one end of the main body 11 in the length direction of the accommodating cavity 12 .

[0072] It can be understood that the positioning column 111 is used to position the protective film assembly 2 , and the positioning column 111 is coplanar with the accommodating cavity 12 .

[0073] Specifically, the positioning column 111 includes a first positioning column disposed close to the top step 15 and a second positioning column disposed away from the top step 15 , wherein one of the positioning columns 111 is used for foolproofing.

[0074] Furthermore, in this embodiment, an elastic locking member and a connecting through hole are also provided on one side of the main body 11 close to the second positioning column 111. The elastic locking member is connected to the accommodating chamber 12 through the connecting through hole, and abuts against the device to be film-laminated arranged in the accommodating chamber 12, so as to realize the limiting of different models of devices to be film-laminated in the accommodating chamber.

[0075] Furthermore, a stop portion 133 is provided at one end of the frame 13 away from the top step 15 .

[0076] It can be understood that the stop portion 133 is arranged at the end of the frame 13 away from the top step 15 to stop the pressing piece 142 from sliding at the end away from the top step 15, but does not hinder the pressing piece 142 from sliding on the accommodating cavity 12. Its height is higher than the accommodating cavity 12, and the material should have sufficient hardness and wear resistance to provide sufficient resistance to prevent the pressing piece 142 from sliding and falling off the track 132 when it is not needed.

[0077] Specifically, two groups of stop portions 133 are symmetrically arranged relative to the accommodating cavity 12 .

[0078] See also Figure 6 - Figure 7 The second embodiment of the utility model provides a film sticking assembly 3, including a protective film assembly 2 and the aforementioned film sticking tool 1, the protective film assembly 2 is installed on the film sticking tool 1; the protective film assembly 2 includes a protective film 21, a positioning film 22 and a bottom film 23, the protective film 21 is arranged between the positioning film 22 and the bottom film 23, the protective film 21 is used to be attached to the screen of the device to be filmed and protect the screen, the positioning film 22, the protective film 21 and the bottom film 23 are arranged from top to bottom, the protective film 21 is provided with an adhesive layer 211, and the bottom film 23 is connected with a drawstring 231.

[0079] Furthermore, a film extraction opening is provided on one end of the main body 11 away from the top step 15 . The film extraction opening is arranged along the width direction of the main body and is arranged close to the stop portion 133 .

[0080] Specifically, the film extraction port provides an operating space for pulling out the extraction belt 231, and the bottom film 23 can be removed from the film extraction port.

[0081] It can be understood that the connection between the base film 23 and the drawstring 231 adopts hot-melt technology to make the two firmly bonded together. The base film 23 protects the adhesive layer 211 set on the protective film 21. Specifically, there is also adhesive on the positioning film 22, and its function is to locate the position of the protective film 21. The positioning film 22 has a positioning hole 221 corresponding to the positioning column 111. The positioning hole 221 cooperates with the positioning column 111 to ensure that when the film is applied, the protective film assembly 2 and the screen of the device to be applied are facing each other to prevent the protective film 21 from being attached crookedly.

[0082] Specifically, during the film pasting operation, the device to be pasted with the film is placed in the accommodating chamber 12, and the screen of the device to be pasted with the film is first cleaned, and the positioning hole 221 on the protective film assembly 2 is aligned with the positioning column 111, and the protective film assembly 2 is placed on the screen surface; then the pressing assembly 14 is installed on the frame 13 of the main body 11 through the installation notch 1311, and the concave through groove 1412 on the pressing bracket 141 is accurately aligned with the slide rail 131, and the pressing piece 142 abuts against the top surface 151 of the top step 15. After the pressing assembly 14 is installed, the drawstring 231 on the bottom film 23 is pulled out along the side away from the top step 15, and then the pressing piece 142 is aligned with the bottom film 23. The pressing member 142 applies a force to the accommodating cavity 12, and the pressing member 142 passes through the inclined surface 152 of the top step 15 until the pressing member 142 abuts against the track 132. The pressing member 142 descends on the track 132 with the slope 1321 and continues to slide along the length direction of the track 132. During the sliding process, the roller 1421 abuts against the screen of the electronic device to perform an exhaust operation, and finally stops sliding after sliding to the abutment stop portion 133. Then the pressing component 14 is pulled back to the side of the installation notch 1311 along the same trajectory. This is a back and forth pressing, and then the positioning film 22 is torn off to complete the film sticking work. If necessary, multiple reciprocating pressings can also be performed.

[0083] The utility model adopts a film sticking component 3, and a pressing component 14 presses steadily so that the protective film 21 is stuck on the screen of the device to be stuck without bubbles, and the pressing process is smooth without jamming.

[0084] Compared with the prior art, the film sticking tool and film sticking assembly provided by the utility model have the following advantages:

[0085] 1.

[0086] 2. In the film sticking tool provided in the embodiment of the utility model, the height of the top step is higher than the height of the track relative to the height of the accommodating cavity. The top step serves as a guide to ensure that the connection of the pressing component is accurately aligned, providing additional stability and support, making the sliding of the pressing component smoother and more stable, reducing resistance during the connection or sliding process, and improving efficiency.

[0087] 3.
