[0001] The utility model relates to a film pasting auxiliary equipment technical field, concretely relates to a universal positioning base with elastic positioning structure and film pasting device, and is suitable for the precise installation of the protective film of mobile phone, tablet computer and other electronic equipment. BACKGROUND
[0002] In the prior art, the traditional film pasting positioning device adopts a four-side elastic spring structure, and the device is centrally positioned through symmetrical elastic force. However, the structure has the following defects:
[0003] The positioning is easy to deviate: if the device is touched by external force (such as uneven force of hand) during the film pasting process, the balance of the elastic force of the four-side spring is broken, the device deviates from the center, and it is impossible to achieve 100% precise positioning;
[0004] The compatibility is limited: the spring with fixed elastic force can only be adapted to devices with small size difference, and it is difficult to be compatible with devices with large size difference, and the cost is high.
[0005] Therefore, the utility model provides a composite positioning structure of "fixed side + elastic side", which solves the above problems through unilateral fixation and opposite elastic abutment. UTILITY MODEL CONTENTS
[0006] In view of this, the utility model provides a universal positioning base and film pasting device which are accurate in positioning, strong in compatibility and low in cost, and solve the problems of easy deviation of positioning and poor device adaptability in the prior art.

The technical scheme provides stable physical limiting through two perpendicular fixed surfaces, ensures that the edge of the device is fixed and does not move, solves the problem of easy deviation of the traditional elastic central structure, is more stable, and has higher film pasting precision.
[0008] Optionally, a plurality of stop holes are formed in the base body, the horizontal spring and the vertical spring are detachably installed in the stop holes, and the installation positions of different stop holes are selected to abut and position the device to be pasted with film of different sizes. Through multi-stop adjustment, the mainstream mobile phone or tablet size can be adapted without replacing hardware, and the compatibility rate is effectively improved.
[0009] Further to the foregoing scheme, the gear holes are linearly arranged along the transverse direction and the longitudinal direction of the base body respectively, and the clamping blocks are in interference fit or snap connection with the gear holes. The elastic sheet can be disassembled and the gear position can be switched without tools, and the adaptation process only takes 5-10 seconds, thereby improving the user experience.
[0010] Optionally, the bottom of the base body is provided with a guide inclined angle for guiding the film-to-be-pasted equipment to enter the accommodating cavity, the guide inclined angle guides the equipment to quickly slide into the accommodating cavity, reduces the alignment time, and improves the film pasting efficiency. The accommodating cavity is also provided with a blocking strip for positioning the top of the film-to-be-pasted equipment, the blocking strip limits the movement of the equipment in the height direction, and the blocking strip is vertically matched with the first fixed surface and the second fixed surface to form a three-dimensional positioning structure.
[0011] Optionally, the transverse elastic sheet and the longitudinal elastic sheet are arranged in an "L" shape and are integrated with the base body, the long side of the elastic sheet is fixed to the base body, and the short side extends to the center of the accommodating cavity and forms an elastic abutting force. The elastic sheet adopts an "L" shape design to save space, avoid occupying too much space of the accommodating cavity, and adapt to narrow frame equipment.
[0012] In the second aspect of the utility model, a film pasting device is provided, which comprises the universal positioning base described above, and the top of the base body is provided with a positioning column for mounting a positioning strip. The positioning column fixes the position of the protective film, ensures the accurate alignment of the film and the equipment screen, and solves the core pain point of "misalignment" when manually pasting the film. After the positioning strip with the protective film is mounted on the positioning base, the bottom of the positioning base is directly buckled on the film-to-be-pasted equipment to quickly paste the film.
[0013] Optionally, the base body is provided with guide rails on both sides of the top, the sliding block is slidably mounted on the guide rails, and the roller is rotatably mounted in the sliding block. The roller is used to uniformly press and paste the protective film to the surface of the film-to-be-pasted equipment, avoids bubbles or wrinkles caused by uneven force when manually pasting the film, and effectively improves the film pasting success rate.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] Accurate positioning: the fixed surface provides rigid support, and the elastic sheet continuously abuts against the equipment to avoid deviation caused by external interference;
[0016] Wide compatibility: through the elastic sheet gear position adjustment, the mainstream mobile phones and tablet computers of different sizes can be adapted;
