Description

Technical Field

[0001] This utility model relates to the field of film application equipment, and in particular to a film applicator for applying films to electronic products. Background Technology

[0002] With the widespread use of electronic products, screen protectors have become an important accessory for protecting electronic product screens. To ensure accurate adhesion of screen protectors to electronic product surfaces, various screen protector applicators have emerged. Screen protector applicators typically include a base, a positioning structure, and an application mechanism, used to assist users in accurately applying the screen protector to the electronic product surface, avoiding problems such as air bubbles and misalignment. Currently, there are various types of screen protector applicators on the market. For example, CN221520169U discloses a universal curved roller screen protector applicator, which includes an applicator base with a phone positioning cavity. An adjustment seat is slidably mounted within the phone positioning cavity, allowing adjustment of the size of the phone positioning cavity. The phone is positioned within the phone positioning cavity and fixed by the adjustment seat. This applicator can move up and down to adjust the screen protector length, adapting to different phone sizes, thanks to the adjustment seat. However, this technical solution uses friction to achieve positioning of the adjustment seat, which has significant drawbacks—excessive friction makes it difficult for the adjustment seat to slide, causing inconvenience for the user; insufficient friction leads to unstable terminal fixation, affecting the quality of the screen protector application.

[0003] The above problems urgently need to be addressed. Utility Model Content

[0004] The main purpose of this invention is to provide a screen protector that can be used to apply screen protectors to electronic products of different sizes, and is easy to adjust and has stronger positioning stability.

[0005] This utility model proposes a film applicator, comprising:

[0006] The base has a receiving cavity for accommodating the product to be applied with film;

[0007] A terminal positioning mechanism, disposed on the base, is used to fix the product to be coated in the receiving cavity;

[0008] A membrane positioning structure is provided on the base for fixing the membrane above the receiving cavity;

[0009] The roller film application module is slidably mounted on the base and is used to press the film to adhere it to the product to be filmed;

[0010] The terminal positioning mechanism includes an adjustment frame that is slidably installed and slides along the length of the receiving cavity, and an elastic structure that acts on the adjustment frame. The adjustment frame drives the elastic structure to stretch or contract by sliding to generate elastic force. The elastic force generated by the elastic structure acts on the adjustment frame so that the adjustment frame is pressed tightly against the end of the product to be filmed, thereby fixing the product to be filmed in the receiving cavity.

[0011] Preferably, when the elastic structure is in its natural state without generating elastic force, the position of the adjusting bracket is the initial position, which is located within the receiving cavity. The maximum effective adjustment position of the adjusting bracket is located at the end of the receiving cavity in the length direction. When the adjusting bracket slides from the initial position to its maximum effective adjustment position, the elastic structure generates an effective elastic force to fix the product to be applied. By sliding the adjusting bracket to match products of different lengths to be applied, when the product to be applied is inserted into the receiving cavity, the end of the product to be applied abuts against the adjusting bracket to slide and match the length of the product to be applied. The elastic structure generates an effective elastic force, causing the adjusting bracket to hold and fix the product to be applied within the receiving cavity.

[0012] Preferably, the elastic structure includes a tension spring disposed on the base, one end of the tension spring being fixed and the other end being connected to the adjustment frame.

[0013] Preferably, the bottom of the receiving cavity is provided with a first sliding groove on both sides, the adjusting frame is provided with a first sliding block and a spring fixing head corresponding to the first sliding groove, the first sliding block slides in the first sliding groove, the spring fixing head extends from the first sliding groove to the back of the base, the tension spring is provided on both sides of the back of the base, and the other end of the tension spring is connected to the spring fixing head.

[0014] Preferably, the two side walls along the length direction of the receiving cavity are provided with a second sliding groove and an access groove that communicates with the second sliding groove and has a sliding entrance at the upper end. The two outer sides of the adjusting frame are provided with a second sliding block corresponding to the second sliding groove, and the second sliding block slides into the second sliding groove from the access groove.

[0015] Preferably, the adjustment frame is provided with a charging port positioning head for inserting into the bottom charging port of the product to be coated.

[0016] Preferably, the adjustment frame is provided with a receiving platform extending towards the product to be coated for receiving the end of the product to be coated, and the receiving platform is located on both sides of the charging port positioning head.

[0017] Preferably, the adjustment frame includes a positioning head setting part and a first sliding block setting part, the charging port positioning port is set on the positioning head setting part, the first sliding block is set on the first sliding block setting part, and the positioning head setting part and the first sliding block setting part are provided with spaced openings on both sides.

[0018] Preferably, the end face of the adjustment frame facing the product to be coated has raised texture.

[0019] Preferably, it further includes a width direction clamping structure for positioning the product to be coated in the width direction of the product to be coated. The width direction clamping structure includes cantilever clamping heads disposed on both sides of the receiving cavity in the width direction. The cantilever clamping head includes a cantilever extending in the length direction of the receiving cavity and capable of elastically swinging in the width direction of the receiving cavity, and a clamping head disposed at the end of the cantilever.

[0020] Preferably, the membrane positioning structure includes a membrane positioning column one disposed on the base and a membrane positioning column two disposed on the adjustment frame, with the membrane positioning column one and the membrane positioning column two located at opposite ends of the length direction of the receiving cavity.

[0021] Preferably, the roller film application module includes a sliding frame slidably mounted on the base and a pressure roller slidably mounted on the sliding frame. The sliding frame and the pressure roller span the receiving cavity and slide along the length of the receiving cavity. The pressure roller is an elastic roller whose rolling surface can be elastically pressed.

[0022] Preferably, the pressure roller is a rubber roller or a foam roller.

[0023] Preferably, the base has slide rails on both outer sides along its length, and the sliding frame has sliding grooves adapted to the slide rails and positioning buckles located below the sliding grooves. The sliding grooves are fitted onto the slide rails, and the positioning buckles are fastened below the slide rails, thereby realizing the sliding connection between the sliding frame and the base.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. The screen protector provided in this application uses an elastic structure to limit the positioning of the adjustment frame after adjustment. The structure is simple, the adjustment is convenient, and the positioning stability is stronger. It can match products of different lengths to be covered (such as mobile phones) and achieve adaptive adjustment. Compared with the prior art, the elastic force generated by the elastic structure acts on the adjustment frame, so that the adjustment frame is pressed tightly against the end of the product to be covered, thereby fixing the product to be covered in the receiving cavity. This overcomes the problems of existing adjustable screen protector devices that rely on friction to position the adjustment seat, such as excessive friction causing difficulty in sliding the adjustment seat or insufficient friction causing unstable terminal fixation.

[0026] 2. By setting a charging port positioning head and a width-direction clamping structure, the product to be applied is positioned in the width direction, and the clamping width can be adjusted. Although the width range is not large, the width of different sized mobile phones is not much different, so it can match the width of different sized mobile phones. Attached Figure Description

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] Reference Figures 1 to 8 This utility model provides a screen protector applicator for applying screen protectors to mobile phones. The applicator includes a base 1, a screen protector positioning structure for positioning the screen protector on the base, a terminal positioning mechanism for fixing the mobile phone on the base, and a roller applicator module 3 for applying the screen protector to the mobile phone.

[0041] The base 1 has a receiving cavity 10 for accommodating a mobile phone. The receiving cavity 10 has a first sliding groove 11 on both sides of its bottom, and a second sliding groove 12 and an access groove 13 that communicates with the second sliding groove 12 and has a sliding entrance at its upper end are provided on the two side walls of the receiving cavity 10 along its length.

[0042] A terminal positioning mechanism is mounted on the base 1 to fix the mobile phone within the receiving cavity 10. This terminal positioning mechanism includes an adjustment frame 2 slidably mounted along the length of the receiving cavity 10 and a spring structure acting on the adjustment frame 2. The adjustment frame 2, through sliding, causes the spring structure to stretch or contract, generating elastic force. The elastic force generated by the spring structure acts on the adjustment frame 2, causing the adjustment frame 2 to press tightly against the end of the mobile phone, thereby fixing the mobile phone within the receiving cavity 10 along its length.

[0043] When the elastic structure is in its natural state without generating elastic force, the position of the adjusting bracket 2 is the initial position, which is located within the receiving cavity 10. The maximum effective adjustment position of the adjusting bracket 2 is located at the front end of the receiving cavity 10 in the length direction. When the adjusting bracket 2 slides from the initial position towards its maximum effective adjustment position, the elastic structure generates an effective elastic force to fix the mobile phone. Different lengths of mobile phones can be matched by sliding the adjusting bracket 2. When the mobile phone is inserted into the receiving cavity 10, one end of the mobile phone abuts against the bottom end of the receiving cavity, and the other end abuts against the adjusting bracket 2 to slide and adapt to the length of the mobile phone. At this time, the elastic structure generates an effective elastic force, causing the adjusting bracket 2 to fix the mobile phone in the receiving cavity 10 in the length direction.

[0044] like Figure 2 As shown, the elastic structure includes a tension spring 4 mounted on the base 1. The adjusting frame 2 has a first sliding block 21 corresponding to the first sliding groove 11 and a second spring fixing head 22. The first sliding block 21 slides within the first sliding groove 11, and the second spring fixing head 22 extends from the first sliding groove 11 to the back of the base 1. The tension spring 4 is located on both sides of the back of the base 1. A first spring fixing head 15 is located on the back of the base 1. One end of the tension spring 4 is fixed to the first spring fixing head 15 via a first connecting ring, and the other end of the tension spring 4 is fixed to the second spring fixing head 22 via a second connecting ring. When the adjusting frame 2 moves towards the front end of the receiving cavity, the adjusting frame stretches the tension spring 4, thereby generating an effective elastic force to return the adjusting frame 2 to its initial position.

[0045] The two outer sides of the adjustment frame 2 are provided with second sliding blocks 23 corresponding to the second sliding groove 12. The second sliding blocks 23 slide from the access groove 13 into the second sliding groove 12. By sliding the first sliding block 21 in the first sliding groove 11 and the second sliding block 23 in the second sliding groove 12, the adjustment frame is slidably connected to the base at the bottom and sides.

[0046] like Figure 5 , 6 As shown, the adjustment frame 2 is equipped with a charging port positioning head 24 for inserting into the charging port at the bottom of the mobile phone. The charging port positioning head 24 is located in the center of the adjustment frame 2. The adjustment frame 2 is also equipped with receiving platforms 25 extending towards the mobile phone to receive the end of the mobile phone, with the two receiving platforms 25 located on both sides of the charging port positioning head 24. When the mobile phone is placed in the receiving cavity, the upper end of the mobile phone is placed on the receiving platform 25, and the charging port positioning head 24 is inserted into the charging port of the mobile phone to further position the mobile phone.

[0047] The adjustment bracket 2 includes a positioning head setting part, a first sliding block setting part, and a second sliding block setting part. A charging port positioning head 24 is mounted on the positioning head setting part, a first sliding block 21 is mounted on the first sliding block setting part, and a second sliding block 23 is mounted on the second sliding block setting part. The positioning head setting part, the first sliding block setting part, and the inner side of the second sliding block setting part are all provided with spaced openings 26. The spaced openings 26 allow the portions of the positioning head setting part, the first sliding block setting part, and the second sliding block setting part facing the mobile phone to swing independently, thus allowing for slight elastic swinging in the up, down, left, and right directions. If there is a positional difference between the charging port positioning head 24 and the mobile phone charging port in the up and down direction, and they cannot be aligned, the charging port positioning head 24 can be pressed to align it with the mobile phone charging port.

[0048] The adjustment bracket 2 has raised texture 28 on the end face facing the mobile phone, which better abuts against the end of the mobile phone.

[0049] like Figure 3 , 4 As shown, the screen protector applicator also includes a width-direction clamping structure for positioning the phone in its width direction. The width-direction clamping structure includes cantilever clamping heads 14 located at the bottom end of the receiving cavity 10 and on both sides in the width direction. Each cantilever clamping head 14 includes a cantilever 141 extending along the length direction of the receiving cavity 10 and elastically swinging in the width direction of the receiving cavity 10, and a clamping head 142 located at the end of the cantilever 141. This allows the clamping head 142 to swing left and right under external force, thus accommodating phones of different widths. When the phone is placed in the receiving cavity, the clamping heads 142 abut against both sides of the phone, positioning it in the width direction.

[0050] The membrane positioning structure 3 is mounted on the base 1 and is used to fix the membrane above the receiving cavity 10. For example... Figure 3 As shown, the film positioning structure includes a film positioning post 17 mounted on the base 1 and a film positioning post 27 mounted on the adjustment frame 2. The film positioning post 17 and the film positioning post 27 are located at opposite ends of the length of the receiving cavity 10. In use, the mobile phone is fixed inside the receiving cavity 10. Film positioning strips with adhesive layers are fitted onto the film positioning posts 17 and 27. The mobile phone film is positioned above the mobile phone, and the film positioning strips are attached to the release layer of the mobile phone film, thus positioning the mobile phone film above the mobile phone. Then, the roller film application module is pushed from one end of the receiving cavity 10 to the other end. The pressure roller on the roller film application module presses the mobile phone film down and adheres it to the mobile phone. Finally, the release layer of the mobile phone film is peeled off, thus completing the mobile phone film application.

[0051] like Figure 7-8As shown, the roller screen protector module 3 is slidably mounted on the base 1 and is used to press the screen protector onto the mobile phone. The roller screen protector module 3 includes a sliding frame 31 slidably mounted on the base 1 and a pressure roller 32 rolled on the sliding frame 31. The sliding frame 31 and the pressure roller 32 span the receiving cavity 10 and slide along the length of the receiving cavity 10. Slide rails 16 are provided on both outer sides along the length of the base 1. The sliding frame 31 has a sliding groove 311 adapted to the slide rail 16 and a positioning buckle 312 located below the sliding groove 311. The sliding groove 311 is fitted onto the slide rail 16, and the positioning buckle 312 is fastened below the slide rail 16, realizing the sliding connection between the sliding frame 31 and the base 1. The pressure roller 32 is an elastic roller, and its rolling surface can be elastically pressed, which can better fit the mobile phone screen, even curved screens. Specifically, the pressure roller can be a rubber roller or a foam roller, with a rolling surface that has good elasticity.

[0052] This screen protector applicator, through the cooperation of the adjusting bracket 2 and the elastic structure, can adapt to mobile phones of different lengths. Simultaneously, the charging port positioning head 24 and the cantilever clamping head 14 work together to position the phone in the width direction, further improving the accuracy of the screen protector application. The pressure roller 32 in the roller screen protector module 2 is an elastic roller that can elastically deform according to the shape of the phone's surface, ensuring a tight fit between the film and the phone surface and preventing air bubbles.
