DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] See also Figures 1 to 4 A clamp 10 for laminating a cover plate and a circular display module comprises: a clamp base 100, a pressing plate 200 and a connecting member 300. The clamp base 100 is provided with a first receiving groove 110 for placing the cover plate, and the first receiving groove 110 is provided with a plurality of through holes 111. A vacuum chamber 112 is provided below the first receiving groove 110, and the first receiving groove 110 is communicated with the vacuum chamber 112 through the through holes 111. A second receiving groove 210 for placing a display screen is provided on one side of the pressing plate 200, and a limiting portion 211 is provided on one side of the second receiving groove 210. The pressing plate 200 is provided with an adsorption button 220 on a side away from the second receiving groove 210, and the adsorption button 220 is used to adsorb the display screen into the second receiving groove 210. The connecting member 300 is respectively connected to the clamp base 100 and the pressing plate 200.

[0026] It should be noted that a plurality of through holes 111 are provided on the first receiving groove 110. When the cover plate is placed in the first receiving groove 110, the cover plate needs to completely cover all the through holes 111. The cover plate is adsorbed and fixed by a vacuum chamber 112 connected to the through holes 111, so that the cover plate will not rotate or deviate. The limiting portion 211 on one side of the second receiving groove 210 is used to limit the display screen, so that the display screen will not rotate or deviate when placed in the second receiving groove 210. The display screen is adsorbed and fixed in the second receiving groove 210 by rotating the adsorption button 220. The clamp base 100 and the pressing plate 200 are connected by a connecting member 300, so that the clamp base 100 and the pressing plate 200 are buckled. The adsorption button 220 is rotated in the opposite direction to release the display screen, and then the adsorption button 220 is gently pressed to make the cover plate fit the display screen.

[0027] See also Figure 2In one embodiment, a plurality of alignment grooves 120 are provided on the clamp base 100, and the alignment grooves 120 are provided at the edge of the first receiving groove 110. In this way, the alignment grooves 120 are aligned with auxiliary alignment lines provided on the cover plate itself, thereby ensuring that the cover plate is accurately placed on the first receiving groove 110.

[0028] Please refer again Figure 2 In one embodiment, a paint layer 121 is disposed on the alignment groove 120. This configuration makes it easier for the operator to accurately place the cover plate in the first accommodation.

[0029] See also Figure 2 and Figure 4 In one embodiment, a plurality of limit grooves 130 are provided on the clamp base 100, and a plurality of limit blocks 230 are provided on the pressing plate 200. The limit grooves 130 and the limit blocks 230 are arranged in alignment with each other. The limit grooves 130 on the clamp base 100 and the limit blocks 230 on the pressing plate 200 are aligned and snap-fitted, thereby increasing the fitting accuracy between the cover plate and the display screen.

[0030] See also Figure 4 In one embodiment, a third accommodating groove 240 for placing the FPC board is provided on the pressing plate 200, and the third accommodating groove 240 is provided on one side of the limiting portion 211. Usually, the display screen needs to be attached to the cover plate in the unfolded state, so sufficient space needs to be reserved for placing the FPC board connected to the display screen.

[0031] In one embodiment, the depth of the first receiving groove 110 is 0.5 mm less than the depth of the cover plate, and the depth of the second receiving groove 210 is set to be the same as the depth of the display screen.

[0032] It should be noted that a gap of 1.05mm is left after the clamp base 100 and the pressure plate 200 are buckled together, and a gap of 0.3mm needs to be left between the cover plate and the display screen to judge the alignment. When the alignment is accurate, the display screen is released by rotating the adsorption button 220 in the opposite direction, so that the display screen and the cover plate are fitted together. Therefore, the depth of the first receiving groove is set to be 0.5mm smaller than the depth of the cover plate, the thickness of the optical adhesive layer set on the cover plate is 0.25mm, and the depth of the second receiving groove 210 is set to be the same as that of the display screen, so that the gap between the cover plate and the display screen is 0.3mm.

[0033] Please refer again Figure 4 In one embodiment, a button support 250 is provided on a side of the pressing plate 200 away from the second receiving groove 210 , and the button support 250 is connected to the adsorption button 220 , and the button support 250 is used to support the adsorption button 220 .

[0034] In one embodiment, the surfaces of the first receiving groove 110 and the second receiving groove 210 are provided with a scratch-resistant coating, thereby preventing the cover plate and the display screen from being scratched and damaged during the bonding process, which would result in reduced product quality.

[0035] In one embodiment, the connector 300 is a bolt connector, which can meet the requirements of multi-angle and multi-directional connections. In this embodiment, when the clamp base 100 and the pressure plate 200 are engaged, the pressure plate 200 needs to be rotated 180 degrees through the connector 300. The characteristics of the bolt connector meet the requirements of this embodiment.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
