[0002] Liquid crystal glass is a high-tech optoelectronic glass product, which is made by encapsulating liquid crystal film sandwiches under high temperature and high pressure. The core feature of this glass is that it can control the arrangement of liquid crystal molecules through electric current, thereby switching between transparent and opaque states. In the production and manufacturing of liquid crystal glass substrates, the capacity of the post-process cannot match the capacity of the hot end. Semi-finished product area, so the glass substrates need to be packaged. To prevent static electricity between glass substrates, spacer paper is required to separate the glass substrates from each other.

[0003] When operating the spacer paper, a vacuum suction cup is usually used to adsorb the spacer paper. When the vacuum suction cup is adsorbing the spacer paper, the adsorption force generated by the vacuum suction cup is when adsorbing the spacer paper. If there are wrinkles on the surface of the spacer paper, when the vacuum suction cup adsorbs the position of the wrinkles, a vacuum environment cannot be formed at the position of the wrinkles of the spacer paper, and it is easy to fall off. At the same time, the spacer paper with wrinkles on the surface is covered between the liquid crystal glass substrates after adsorption, increasing the local distance between the liquid crystal glass substrates, and cannot play a good spacing and protection role.

[0009] Furthermore, the axial cross-section of the flattening roller and the rubber sleeve is a concentric circle structure, and multiple groups of friction blocks are evenly arranged on the circumferential outer side of the rubber sleeve.

After the wrinkles are stretched, the spacer paper can be more evenly distributed between the liquid crystal glasses, avoiding indentations or scratches on the glass surface due to local pressure concentration at the wrinkles. This is especially important for high-value liquid crystal glasses, and can effectively maintain the appearance quality and optical properties of the glass. The flat spacer paper can better play a buffering role. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0028] Specific implementation method 1: Please refer to Figure 1-6 The present invention provides a technical solution: a liquid crystal glass spacer paper clamping device, comprising a paper clamping assembly 100, wherein the paper clamping assembly 100 is fixedly arranged at the end of a mechanical arm 200, the paper clamping assembly 100 comprises a first fixed seat 2, and a second fixed seat 21 is fixedly arranged on one side of the first fixed seat 2, and a suction plate 3 is connected between the second fixed seat 21 and the first fixed seat 2, and a vacuum suction cup 31 is fixedly installed at the bottom of the suction plate 3, and a spacer paper flattening assembly 4 is installed at the bottom of the first fixed seat 2 and the second fixed seat 21, and the spacer paper flattening assembly 4 comprises a flattening roller 41 covering the bottom of the second fixed seat 21, and special-shaped seats 40 are fixedly arranged on both sides of the second fixed seat 21, and a rubber sleeve 42 is fixedly installed on the outer side of the flattening roller 41, and buffer assemblies 44 are fixedly installed at both ends of the flattening roller 41.

[0029] Working principle: A swing cylinder 201 is installed at the end of the mechanical arm 200, and the mechanical arm 200 drives the paper clamping assembly 100 to move through the swing cylinder 201, and the swing cylinder 201 can rotate 180 degrees; when clamping paper, the swing cylinder 201 rotates 180 degrees to drive the paper clamping assembly 100 to move, and a plurality of groups of equidistantly arranged vacuum suction cups 31 are evenly arranged at the bottom of the paper clamping assembly 100 to clamp the paper; the paper placing process is that the swing cylinder 201 rotates 180 degrees in the opposite direction, and the vacuum suction cup 31 releases the vacuum; the paper is placed on the liquid crystal glass of the bracket; specifically, the working principle of the paper clamping assembly 100 is: the paper clamping assembly 100 is driven to move downward, so that the paper clamping assembly 1 00 The flattening rollers 41 on both sides of the bottom and the rubber sleeves 42 on the outside thereof first contact the two sides of the surface of the spacer paper. When the paper clamping assembly 100 continues to move downward, the two sets of rubber sleeves 42 cover the two sides of the surface of the spacer paper and pull the two sides of the surface of the spacer paper outward, which can pull the wrinkles on the surface of the spacer paper to make the surface of the spacer paper flat. At this time, the paper clamping assembly 100 continues to move downward, and a large number of vacuum suction cups 31 cover the surface of the spacer paper, and vacuum is used to adsorb the spacer paper to avoid wrinkles on the surface of the spacer paper. The location of the wrinkles of the spacer paper cannot form a vacuum environment and is easy to fall off. At the same time, the spacer paper is spread evenly on the glass substrate. The spacer paper has the following advantages between the liquid crystal glass and the glass substrate: after the wrinkles are stretched, the spacer paper can be more evenly distributed between the liquid crystal glass, avoiding indentations or scratches on the glass surface due to local pressure concentration at the wrinkles; this is particularly important for high-value liquid crystal glass, and can effectively maintain the appearance quality and optical properties of the glass; the flat spacer paper can better play a buffering role, and when subjected to external impact, it can more effectively disperse the impact force and reduce the possibility of liquid crystal glass breakage; the wrinkles on the surface of the spacer paper are stretched in the following manner: the buffer sleeve 441, the force arm 442 and the limit rod 444 are combined to form an acute triangle, and when the rubber sleeve 42 is subjected to force, the buffer sleeve 441 and the force arm 442 ... 42 increases, and at the same time, the limit seat 443 movably connected to the force-bearing arm 442 moves forward and compresses the limit spring 445 sleeved on the limit rod 444. Multiple groups of friction blocks 43 are evenly arranged on the outside of the rubber sleeve 42, and the friction blocks 43 are also made of rubber. The two rubber sleeves 42 move outward synchronously, which can pull apart the spacer paper with wrinkles on the surface, so that the surface of the spacer paper is smooth for use. At the same time, the arrangement of the friction block 43 on the outside of the rubber sleeve 42 is convenient for driving the spacer paper to be stressed. When the force on the rubber sleeve 42 disappears, the compressed limit spring 445 rebounds, prompting the rubber sleeve 42 to return to its initial position.
