The first embodiment is as follows:
referring to fig. 1 to 5, the present invention provides a C-shaped screen assembly 1 attaching tool, which is used for attaching a flexible inner screen to the inner side of a C-shaped outer screen to form a screen assembly 1, wherein the C-shaped outer screen includes a straight area and curved areas located at two sides of the straight area and in smooth transition connection with the straight area; the flexible inner screen and the C-shaped outer screen are attached to each other in a mode that the force applying mechanism 3 applies force to the elastic body 2; the elastic body 2 comprises a flat attaching part 21 and curved attaching parts 22 which are positioned on two sides of the flat attaching part 21 and integrally connected with the flat attaching part 21, and an accommodating cavity 23 which is combined and matched with the force applying end is formed in the curved attaching parts 22; the force applying end comprises a flattening part S1 and a bending part S2, the flattening part S1 enables the flexible screen to be attached to the straight area in a mode of contacting and applying force to the flat attaching part 21, and the bending part S2 is embedded into the accommodating cavity 23 to enable the flexible screen to be attached to the arc bending area in a mode of contacting and applying force to the bending part 22.
It should be noted that, in this embodiment, an included angle between the curved region and the flat region of the C-shaped screen is less than or equal to 90 °, and the flexible inner screen cannot be directly pressed to the opposite screen on the inner side of the curved glass by a direction perpendicular to the flat region. In addition, it should be noted that, for the screen with the included angle between the arc bending area and the straight area being 90 ° to 180 °, the screen can be attached by the technical solution described in this embodiment, and therefore, the protection scope of the present invention should be covered.
Structure of elastic body 2:
as shown in fig. 2, in this embodiment, the elastic body 2 is a silicone block that is integrally injection-molded, the elastic body 2 includes a flat portion 21 and curved portions 22 that are located at two sides of the flat portion 21 and integrally connected with the flat portion 21, and a receiving cavity 23 that is combined with and matches the force application end is formed in the curved portions 22. The inner shape of the housing cavity 23 is adapted to the outer side shape of the force application end of the force application mechanism 3, so that the elastic body 2 is attached to the force application end.
As shown in fig. 2, the thickness of the region where the flat part 21 and the curved part 22 meet is smaller than the average thickness of the flat part 21, and is smaller than the average thickness of the curved part 22 to reduce the force applied to the flexible inner screen by the region. The area is used for attaching the joint of the straight area and the arc-bent area of the screen component 1, and the attaching bent part 22 and the attaching flat part 21 can apply force to the joint in the attaching process, so that the attaching effect of the joint of the C-shaped screen cannot be influenced. In addition, it should be noted that the strength at the joint of the elastic body 2 can be effectively reduced by reducing the thickness, the deformation degree of the curved portion 22 during the fitting process can be increased, and the fitting effect of the curved region can be further increased.
The average thickness of the flattened portion 21 is greater than the average thickness of the bent portion 22 so that the flattened portion 21 can maintain a certain thickness in the direction perpendicular to the flat region after being elongated in the direction parallel to the flat region without generating an excessive fitting pressure in the flat region. It should be noted that when the force applying mechanism 3 acts on the curved region towards both sides, the flattened portion 21 is pulled up by both sides, and in the process, the flattened portion 21 still has a little pressure on the flat region.
The elastic body 2 is provided with 2 bending parts 22 distributed on two sides of the flat part 21, and the outer side surfaces of the flat part 21 and the bending parts 22 are in smooth transition. Meanwhile, the two accommodating cavities 23 are used for accommodating two bending parts S2 to fit the inverted buckling parts on two sides.
Structure of the urging mechanism 3:
as shown in fig. 3, the force applying mechanism 3 is a left slider 31 and a right slider 32 symmetrically arranged, the left slider 31 and the right slider 32 are switched from an attaching state to a detaching state when the screen assembly 1 is attached, the left slider 31 and the right slider 32 respectively include a force applying end and a connecting portion S3, and the connecting portion S3 is used for connecting the force applying end and the driving mechanism 5 to drive the connecting portion S3 to apply force to the elastic body 2. The force application end comprises a flattening part S1 and a bending part S2, the flattening part S1 enables the flexible screen to be attached to the straight area in a mode of contacting and applying force to the flat attaching part 21, and the bending part S2 is embedded into the accommodating cavity 23 to enable the flexible screen to be attached to the arc bending area in a mode of contacting and applying force to the bending part 22.
The force application end and the connecting portion S3 are integrally formed, and the force application mechanism 3 is integrally formed by injection molding of silicone rubber.
As shown in the figure, the thickness of the outer side of the force application end is smaller than that of the inner side of the force application end, so that the pressure on the reverse buckling part of the C-shaped screen is reduced. And the thickness of the bending part S2 is smaller than that of the flattening part S1, and the fitting degree of the C-shaped screen at the reverse buckling part can be increased by reducing the strength of the bending part S2, so that bubbles are prevented from being generated.
In addition, it should be noted that, in this embodiment, the guide post 6 for guiding the sliding block during sliding is further included, and there are 4 guide posts 6 respectively located at the front and rear sides of the driving mechanism 5.
Structure of the drive mechanism 5:
as shown in fig. 1, 4 and 5, the attaching device further has a driving mechanism 5 for driving the force application mechanism 3 to move laterally, and the driving mechanism 55 of the present embodiment is an electric screw rod including a driving motor 51, a screw rod 52, a first nut 53 connecting the screw rod 52 and the left slider 31, and a second nut 54 connecting the screw rod 52 and the right slider 32. It should be noted that the screw 52 has opposite threads at two ends, so that when the driving motor 51 is operated and the screw 52 is rotated, the left slider 31 and the right slider 32 can respectively move linearly to two sides.
It should be noted that the electric screw is only one embodiment as the driving mechanism 5 of the present embodiment, and in other embodiments, the driving mechanism 5 may be an air cylinder or a linear motor.
The working principle of the invention is as follows:
referring to fig. 1, 4 and 5, the force application mechanism 3 is first connected to the driving mechanism 55 and mounted on the bonding jig 43, the elastic body 22 is sleeved on the force application end to form a primary assembly, and then the flexible inner screen is placed on the upper surface of the elastic body 22, and the C-shaped outer screen is placed above the flexible inner screen; then, the attaching jig 43 pushes the attaching device to move in the vertical direction of the straight region, so that the elastic body 22 extends into the C-shaped outer screen, and the flatting part 2121 attaches the flexible inner screen right above the elastic body to the straight region of the C-shaped outer screen, thereby completing the mounting of the straight region; then the driving mechanism 55 works, the screw 52 rotates to make the left slider 31 and the right slider 32 respectively move linearly to both sides, so that the curved part 22 of the elastic body 2 is attached to the curved area of the screen assembly 1; after the attachment is finished, the driving motor 51 works in reverse to make the force application mechanism 33 and the elastic body 22 return to the initial state, and the attachment jig 43 drives the attachment device to separate from the screen assembly 11 and start the assembly of the next screen assembly 11.
