[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 6 As shown, a simple and fast positioning and pressure-maintaining device includes a positioning and pressure-maintaining basic unit 100.

[0027] The positioning and pressure-maintaining basic unit 100 includes an upper splint 5, a lower splint 7 and an elastic pad 3. The upper splint 5 is attached to the upper surface of the lower splint 7, and the elastic pad 3 is attached to the lower surface of the lower splint 7. A positioning lock column 4 is provided on the upper surface of the lower splint 7, and a positioning lock cylinder 2 is provided on the lower surface of the lower splint 7. The positioning lock column 4 of the positioning and pressure-maintaining basic unit 100 located on the lower layer is positioned and docked with the positioning lock cylinder 2 of the positioning and pressure-maintaining basic unit 100 located on the upper layer.

[0028] There are preferably four positioning locking columns 4 distributed around the lower clamping plate 7 .

[0029] Preferably, there are four positioning lock cylinders 2 distributed around the lower clamping plate 7 .

[0030] There are at least two simple and fast positioning and pressure-maintaining devices, which are stacked up and down.

[0031] The upper surface of the lower clamping plate 7 is provided with a lower positioning groove matched with the frame, and the lower surface of the upper clamping plate 5 is provided with an upper positioning groove matched with the frame. The upper positioning groove and the lower positioning groove press the frame up and down.

[0032] An upper magnet 61 is embedded on the lower surface of the upper clamping plate 5 , and a lower magnet 62 is embedded on the upper surface of the lower clamping plate 7 to magnetically cooperate with the upper magnet 61 .

[0033] The upper magnet 61 and the lower magnet 62 are both cylindrical.

[0034] The positioning lock column 4 and the positioning lock cylinder 2 are coaxially installed through the hexagonal cup head stud 1.

[0035] The upper clamping plate 5 is provided with a window matched with the cover plate or the touch screen, and the convex edge of the frame protrudes out of the window and is exposed, so that glue can be applied conveniently.

[0036] The positioning and pressure-maintaining device further includes a counterweight block 200 , which is pressed on the uppermost positioning and pressure-maintaining basic unit 100 to provide a stable pressure for pressure maintenance.

[0037] When the pressure is not maintained, the thickness of the elastic pad 3 is greater than the height of the positioning lock cylinder 2 .

[0038] According to the 3D file of the frame, the position where the lower clamping plate 7 interferes with the frame is designed to avoid interference, and the positioning points are set. At least four lower magnets 62 are installed around the upper side, and an elastic pad 3 made of elastic material is installed on the lower side; the inner frame of the upper clamping plate 7 is made according to the shape of the 3D file of the frame, and upper magnets 61 are also installed at corresponding positions around the lower side, which match the position of the lower magnets 62 on the lower clamping plate 7, and are used for magnetic attraction when the upper and lower clamping plates are stacked.

[0039] The utility model provides a simple and fast positioning and pressure-maintaining device, and its operation process is as follows: Figure 4 As shown:

[0040] (a) Place the lower clamping plate 7 firmly on the work platform and align the frame with the corresponding slot of the lower clamping plate 7.

[0041] (b) The upper clamping plate 5 is roughly aligned with the frame and inserted from above. After reaching the predetermined position, the upper magnet 61 and the lower magnet 62 inlaid in the upper and lower clamping plates are automatically magnetically attracted to align.

[0042] (c) Apply glue evenly on the convex edge of the frame where the cover plate or touch screen is to be pasted, align the frame, and place the cover plate or touch screen.

[0043] (d) Manually press the touch screen or cover plate pasting area for preliminary fixation to form a fitted assembly with the device.

[0044] The most basic pressure-maintaining operation of the device requires two positioning and pressure-maintaining basic units 100 plus appropriate counterweights 200.

[0045] After one unit is bonded, the positioning lock column 4 and the positioning lock cylinder 2 assembled through the positioning and pressure-holding basic unit 100 are nested and stacked. When there is no pressure holding, the thickness h of the elastic pad 3 assembled at the bottom is greater than the height H of the positioning lock cylinder 2. If there is no pressure holding, the pressure holding strength may not meet the operating requirements. Through appropriate counterweight blocks 200, the elastic pad 3 is deformed and acts on the bonding area until the positioning lock column 4 and the positioning lock cylinder 2 are tightly fitted. If there is a pressure holding state, that is, the positioning lock cylinder 2 is subjected to force and starts to support the interval, the deformation of the elastic pad 3 reaches the maximum, the pressure holding strength provided is constant, and the excess gravity is transferred by the positioning lock cylinder 2 to the placement platform to avoid excessive gravity from crushing the bonding components. This feature is crucial in multi-layer stacking.

[0046] Based on the pressure-maintaining process after one unit is bonded, multiple bonded components with devices that have completed the bonding operation can be stacked as needed until the safety upper limit of the material is reached. The actual number of stacked layers depends on the specific situation. Multi-layer stacking can effectively solve the disadvantages of long pressure-maintaining operation time and large floor space for flat paving. At the same time, the gravity of the stack can be used to provide pressure-maintaining force, reducing the use of counterweights or other pressure-maintaining devices, and each layer is subjected to the same force. Figure 5 , 6 As shown, three layers of stacking can be performed.

[0047] The utility model provides a simple and fast positioning and pressure-maintaining device, which is used to solve the problem that in the manufacturing process of narrow-framed displays with cover plates or touch screens, the traditional bonding solution has no jig, only relies on visual alignment, and the bare cover plate or touch screen leads to poor consistency of the finished product; at the same time, it also solves the problem that such bonding operations need to be pressure-maintained after applying glue, and during pressure-maintaining, long-term flat placement occupies a large space and is difficult to maintain pressure. While the narrow-framed display is beautiful, it also means that the frame is relatively fragile. It has a certain strength above and below, which does not affect the operation, but the side is often easy to deform when the top is pressed, resulting in failure of bonding during the operation. This device is made to solve the problems caused by the above-mentioned frame characteristics. Taking advantage of the strong characteristics of the frame above and below, the bottom of the frame is placed on the lower clamping plate 7 of the device, so that the device solidifies the frame, and positions the cover plate or touch screen when it is bonded, and it is also convenient for the mechanized operation of applying glue. By stacking multiple layers of the same model device, space can be saved, and the elastic material can also be deformed by the gravity of the device itself plus the gravity of the counterweight block to provide the force for pressure maintenance. The device has the characteristics of simple structure, simple use, strong reliability, small space occupation and good effect.

[0048] The utility model provides a simple and fast positioning and pressure-maintaining device, which is suitable for assembling positioning and pressure-maintaining of a frame and a touch screen or a cover plate.

[0049] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
