[0036] Referring to Figure 1 and Figure 2 , it is shown that Figure 1 a structural schematic diagram of a support mechanism in an embodiment of the present application is shown, Figure 2 a partial structural sectional view of the support mechanism in Figure 1 An embodiment of the present application provides a support mechanism 10 including a control module 100, a power supply module, an electromagnetic module 200, and a support assembly 300.

[0037] The electromagnetic module 200 includes a connecting sleeve 210 and an electromagnetic assembly 220 mounted on the connecting sleeve 210, the support assembly 300 is movably mounted on the connecting sleeve 210 relative to the connecting sleeve 210, one end of the support assembly 300 is used to carry a glass cover plate, the other end of the support assembly 300 is arranged opposite the electromagnetic assembly 220, the power supply module is electrically connected with the control module 100 and the electromagnetic assembly 220, the control module 100 is used to control the power supply module to provide an amount of current and a direction of current to the electromagnetic assembly 220, so that the electromagnetic assembly 220 repels or attracts the support assembly, thereby realizing the lifting of the support assembly 300. In a specific arrangement, the support assembly 300 has a magnet.

[0038] In specific use, the support mechanism 10 is arranged around a receiving groove opened by a bonding jig, the support assembly 300 in the support mechanism 10 is used to carry the glass cover plate, the receiving groove is used to arrange optical adhesive, the control module 100 of the support mechanism 10 controls the power supply module to provide current in different directions to the electromagnetic assembly 220, so that the electromagnetic assembly 220 has different magnetic poles, thereby being able to generate attractive force or repulsive force on the support assembly 300, so that the support assembly 300 moves towards the direction close to the electromagnetic assembly 220 or moves away from the direction of the electromagnetic assembly 220. It is to be noted that the repulsive force of the electromagnetic assembly 220 makes the glass cover plate on the support assembly 300 spaced apart from the optical adhesive, and then a vacuum bonding machine is used to provide pressure to overcome the magnetic force to press the glass cover plate to the optical adhesive to complete the bonding of the two.

[0039] The support mechanism 10 controls the amount and direction of current provided to the electromagnetic assembly 220 by the control module 100, so that the electromagnetic assembly 220 attracts or repels the support assembly 300. That is, the support assembly 300 is suspended in the electromagnetic assembly 220 by magnetic force. The vacuum laminator provides pressure to overcome the magnetic force and press the glass cover plate on the support assembly to the optical adhesive. Compared with the method of pressing the glass cover plate by overcoming the elastic force of the spring needle, the present application ensures that the magnetic force of the electromagnetic assembly 220 on the support assembly 300 is constant by providing a set amount of current. This can avoid the problem of air bubbles in the product lamination process caused by inconsistent compression or jamming during pressing after multiple pressings of the spring needle. By adjusting the amount of current, the magnetic force can be adjusted. Compared with the fixed elastic force of the spring needle, the support mechanism 10 can adjust the magnetic force, i.e., the support force on the glass cover plate, according to the size of the glass cover plate, to ensure that the glass cover plate and the optical adhesive have a set distance for subsequent lamination.

[0040] To facilitate the design of the support assembly 300, one preferred embodiment includes a support column 310 and a first magnet 320. One end of the support column 310 is movably arranged through the connecting sleeve 210, and the other end of the support column 310 is detachably connected to the first magnet 320 and located inside the connecting sleeve 210. In a specific arrangement, the first magnet 320 is preferably a neodymium iron boron magnet, and the end of the first magnet 320 facing away from the support column 310 is arranged opposite the electromagnetic assembly 220. The electromagnetic assembly 220 drives the support column 310 to rise or fall by repelling or attracting the first magnet 320. It should be noted that when the current is 0, i.e., the power supply is stopped, the electromagnetic assembly 220 stops providing magnetic support to the support assembly 300, and the support assembly 300 can fall on the electromagnetic assembly 220 or be kept above the electromagnetic assembly 220 by the transitional fit with the connecting sleeve 210.

[0041] To prolong the service life of the support column 310, the material of the support column 310 is PEEK (polyether ether ketone). PEEK has physical and chemical properties such as high temperature resistance and chemical resistance, and is a semi-crystalline polymer material. PEEK also has good performance in wear resistance. By using PEEK material, the damage and burr phenomenon that occurs easily with POM material on the market is avoided.

[0042] To facilitate the detachable connection of the first magnet 320 and the support column 310, the support assembly 300 further includes a connecting fastener 330 that penetrates the first magnet 320 and the support column 310. In a specific arrangement, the connecting fastener 330 can be a bolt, screw, or other fastener. Through the above arrangement, damaged support column 310 or first magnet 320 can be replaced in time.

[0043] As shown in Figure 3 As shown in Figure 3 Figure 1 is an exploded schematic view of a support mechanism 10 according to an embodiment of the present application. In order to facilitate the design of the electromagnetic assembly 220, a preferred embodiment of the electromagnetic assembly 220 includes a core 221 and an electromagnetic wire 222, one end of the electromagnetic wire 222 is connected to a power module, and the other end of the electromagnetic wire 222 is wound around the outside of the core 221. It should be noted that the electromagnetic wire 222 is magnetized after being energized by the power module, which is consistent with the principle of an electromagnet. In a specific arrangement, in order to enhance the magnetism of the electromagnetic assembly 220, the core 221 is made in the shape of a hoof. The winding direction of the electromagnetic wire 222 on the hoof-shaped core 221 is opposite.

[0044] In order to make the magnetic performance disappear in time after power failure, specifically, the material of the core 221 is soft iron or silicon steel. It should be noted that both soft iron and silicon steel belong to soft magnetic materials, and the magnetism will disappear in a short time after magnetization, and the magnetism cannot be permanently maintained. Through the above arrangement, the magnetic performance can disappear in time after power failure, and no magnetism will be generated in the non-working state, which has low requirements for the storage location.

[0045] As shown in Figure 4 As shown in Figure 4 Figure 2 is a cross-sectional view of a connecting sleeve 210 according to an embodiment of the present application. In order to facilitate the detachable installation of the support assembly 300 and the electromagnetic assembly 220 in the connecting sleeve 210, so as to facilitate the timely replacement of the components after subsequent damage, a preferred embodiment of the connecting sleeve 210 is provided with a first inner cavity 211 and a clearance hole 212 in communication with the first inner cavity 211, one end of the support assembly 300 can be movably inserted into the clearance hole 212 relative to the connecting sleeve 210, and the other end of the support column 310 is located in the first inner cavity 211 and is arranged opposite to the electromagnetic assembly 220. In a specific arrangement, the support assembly 300 includes a support column 310 and a first magnet 320, the longitudinal section of the support column 310 is in the shape of T, the large end of the T-shaped support column 310 is connected to the first magnet 320, the small end of the T-shaped support column 310 away from the first magnet 320 passes through the clearance hole 212, and the size of the large end of the T-shaped support column 310 is larger than that of the clearance hole 212.

[0046] In order to facilitate the installation of the electromagnetic assembly 220 in the connecting sleeve 210, specifically, the support mechanism 10 further comprises a bearing column 400 arranged in the first inner cavity 211, and the bearing column 400 is used to bear part of the electromagnetic assembly 220. In a specific arrangement, the inner wall of the connecting sleeve 210 is provided with a convex wall 213 along the circumference thereof, and the space surrounded by the convex wall 213 is used to install the bearing column 400, the upper end of the bearing column 400 is used to bear the iron core 221, and a first through hole penetrating the bearing column 400 along the height direction is arranged on the bearing column 400, and the first through hole facilitates the electromagnetic wire 222 to pass through the first through hole and be connected with the power module. In order to strengthen the fixation of the electromagnetic assembly 220 and the connecting sleeve, the bearing column 400 can be a fixed top wire, and is convenient to disassemble, so as to facilitate the disassembly of the electromagnetic assembly 220. Compared with the current spring needle which is difficult to disassemble and cannot confirm the internal defects, the support mechanism 10 of the present application has a simple structure, and each component can be disassembled and connected.

[0047] In order to more conveniently design the control module 100, in a preferred embodiment, the control module 100 comprises a base 110, and an electric current control button 120 and a current direction adjusting button 130 arranged on the base 110, and the electric current control button 120 and the current direction adjusting button 130 are electrically connected with the power module. It should be noted that the electric current control button 120 and the current direction adjusting button 130 are common technical means on the market, and will not be described in detail here.

[0048] The application further provides a lamination jig, which comprises a lamination frame and the support mechanism 10 as described in any of the above embodiments, and the lamination frame is provided with a receiving groove for arranging optical glue, and the support mechanism 10 is arranged on the lamination frame, and the support assembly 300 in the support mechanism 10 is used to bear the glass cover plate.

[0049] Through the above arrangement, the electromagnetic assembly 220 in the support mechanism 10 will generate a magnetic pole repelling the support assembly 300 after being electrified, so that the glass cover plate on the support assembly 300 is spaced from the optical glue, and then the vacuum laminator provides pressure to overcome the magnetic force to press the glass cover plate to the optical glue to complete the lamination of the two.

[0050] The above-mentioned laminating jig, by setting the laminating jig comprising a support mechanism 10, the control module 100 in the support mechanism 10 is used to control the current and current direction of the power module provided in the electromagnetic assembly 220, so that the electromagnetic assembly 220 attracts or repels the support assembly 300, that is, the present application makes the support assembly 300 suspended in the electromagnetic assembly 220 by magnetic force, and the pressure provided by the vacuum laminator can press the glass cover plate on the support assembly to the optical adhesive. Compared with the way of pressing the glass cover plate by overcoming the elastic force of the spring needle, the present application can ensure the constant magnetic force of the electromagnetic assembly 220 on the support assembly 300 by providing a set of current, which can avoid the problem of air bubbles in the product laminating process caused by the inconsistent compression amount of the spring needle after multiple pressing or the jamming during pressing. And the present application can adjust the size of the magnetic force by adjusting the size of the current, compared with the fixed size of the spring needle elastic force, the support mechanism 10 of the present application can adjust the magnetic force, that is, adjust the support force on the glass cover plate according to the glass cover plate of different sizes, so as to ensure that the glass cover plate and the optical adhesive have a set distance for subsequent lamination.
