[0023] In the field of printing, especially in high-precision printing and large-scale industrial production environments that pursue extreme precision and efficiency, the adsorption and conveying technology of large-size glass substrates plays a crucial role. The quality of this technology is directly related to the printing precision and product quality of the final product. However, traditional clamping methods often struggle when faced with large-size glass substrates. Limited by material, structure, and control technology, traditional clamping methods are difficult to achieve uniform and precise adsorption of large-size glass substrates. This not only may cause the glass substrate to shake or displace during conveying, affecting the printing precision, but also may cause damage to the glass substrate due to uneven clamping force. In addition, traditional clamping methods lack sufficient flexibility when handling glass substrates of different thicknesses and sizes. This means that during production, the clamping device needs to be frequently replaced or parameters need to be adjusted to adapt to different specifications of glass substrates. This not only increases production costs, but also prolongs production cycles and reduces production efficiency.
[0024] Therefore, the present application provides a clamping device for adsorption and conveying of large glass substrates.
[0025] As shown in Figs. 1-3 The present application provides a clamping device, which includes an adsorption plate 200 and a cover plate 100.
[0026] In the present application, the first surface of the adsorption plate 200 is fixedly connected to the first surface of the cover plate 100. A plurality of adsorption through holes 202 are formed on the first surface of the adsorption plate 200. For each adsorption through hole 202, an air suction hole 201 corresponding to the adsorption through hole 202 is provided on the second surface adjacent to the first surface of the adsorption plate 200. Each adsorption through hole 202 and the corresponding air suction hole 201 are mutually through. An adsorption groove is provided on the first surface of the cover plate 100, and a cover plate 100 air suction hole 201 is provided on the second surface opposite to the first surface of the cover plate 100. The cover plate 100 air suction hole 201 and the adsorption groove are mutually through.
[0027] Specifically, the first surface of the adsorption plate 200 is fixedly connected to the first surface of the cover plate 100. This fixed connection can be achieved by welding, screwing, bonding, or any other method that can firmly connect the two together, which is not limited in the present application.
[0028] The adsorption through holes 202 are located on the first surface of the adsorption plate 200, and the purpose of the adsorption through holes 202 is to allow gas or vacuum to pass through, so as to generate an attractive force on the first surface of the adsorption plate 200 for clamping objects. For each adsorption through hole 202, there is a corresponding adsorption hole 201 on the second surface (i.e. the surface adjacent to the first surface) of the adsorption plate 200. The adsorption hole 201 and the adsorption through hole 202 are mutually penetrated to form a channel from the first surface to the second surface of the adsorption plate 200. When the gas is extracted from the channel, a negative pressure can be generated around the adsorption through hole 202, so as to adsorb the object.
[0029] The adsorption grooves are located on the first surface of the cover plate 100. One or more grooves 103 are referred to as adsorption grooves, which are used to form a vacuum adsorption cavity with the adsorption plate 200, so as to improve the stability and firmness of clamping.
[0030] The cover plate 100 adsorption holes 201 are located on the second surface opposite to the first surface of the cover plate 100. One or more holes are referred to as cover plate 100 adsorption holes 201, which are mutually penetrated with the adsorption grooves to form a channel from the first surface to the second surface of the cover plate 100. When the gas is extracted from the channel, the gas is extracted through the adsorption holes 201 and the cover plate 100 adsorption holes 201, so that a negative pressure is generated around the adsorption through holes 202 and the adsorption grooves, thereby adsorbing the object. Since the adsorption through holes 202 and the adsorption holes 201, the adsorption grooves and the cover plate 100 adsorption holes 201 are mutually penetrated, it can be ensured that a uniform negative pressure is generated in the entire clamping area, thereby achieving a stable and firm clamping effect.
[0031] Further, as shown in Figs. 1-3 The adsorption plate 200 is rectangular, and a plurality of adsorption through holes 202 are distributed in two rows. The two rows of adsorption through holes 202 are uniformly arranged on the first surface of the adsorption plate 200, and the two rows of adsorption through holes 202 are staggered along the length direction of the adsorption plate 200.
[0032] The adsorption grooves include a first adsorption groove 104, and the first adsorption groove 104 is rectangular. The first adsorption groove 104 is arranged at a position corresponding to the upper row of adsorption through holes 202. The cover plate 100 adsorption holes 201 include two first cover plate 100 adsorption holes 201, and the two first cover plate 100 adsorption holes 201 are arranged on the second surface of the cover plate 100 and are in communication with both ends of the first adsorption groove 104. The adsorption grooves further include a second adsorption groove 105, and the second adsorption groove 105 is U-shaped. The second adsorption groove 105 is arranged at a position corresponding to the lower row of adsorption through holes 202. The cover plate 100 adsorption holes 201 include two second cover plate 100 adsorption holes 201, and the two second cover plate 100 adsorption holes 201 are arranged on the second surface of the cover plate 100 and are in communication with both ends of the U-shaped second adsorption groove 105.
[0033] Specifically, the adsorption plate 200 is rectangular, has a regular and stable structure, and a plurality of adsorption holes 202 are divided into upper and lower rows and uniformly distributed on the first surface of the adsorption plate 200, which helps to ensure uniform distribution of adsorption force on the entire adsorption plate 200. The upper and lower rows of adsorption holes 202 are staggered along the length direction of the adsorption plate 200, which can further optimize airflow distribution and improve adsorption efficiency.
[0034] The first adsorption groove 104 is rectangular and arranged at a position corresponding to the upper row of adsorption holes 202. This design helps to ensure that the adsorption force generated by the upper row of adsorption holes 202 matches the shape of the first adsorption groove 104, thereby improving clamping stability. The second adsorption groove 105 is U-shaped and arranged at a position corresponding to the lower row of adsorption holes 202. The U-shaped design can adapt to objects of different shapes, improving the flexibility and adaptability of clamping. Two first cover plate 100 air inlets 201 are arranged on the second surface of the cover plate 100 and communicate with both ends of the first adsorption groove 104, which can effectively extract air from the first adsorption groove 104 to form negative pressure, thereby enhancing the adsorption effect. Two second cover plate 100 air inlets 201 are also arranged on the second surface of the cover plate 100 and communicate with both ends of the U-shaped second adsorption groove 105, which helps to uniformly extract air from the second adsorption groove 105 to maintain a negative pressure state and improve clamping stability.
[0035] As shown in Fig. 2 The cover plate 100 is rectangular and matches the shape of the adsorption plate 200. Two grooves 103 are formed on the first long side of the cover plate 100, and each cross glass 102 is arranged in the corresponding groove 103, which helps to increase the stability and rigidity of the clamping device and improve its adsorption capacity for the clamped object.
[0036] As shown in Fig. 1 The clamping device further includes an air suction connector 101 arranged on the air inlet 201 of the cover plate 100 for connecting an air suction device. The external air suction device can be connected to the clamping device to achieve air extraction and negative pressure generation.
[0037] The clamping device proposed in the present application achieves efficient and stable clamping effect. The device includes a rectangular adsorption plate and a cover plate. The adsorption plate uniformly distributes a plurality of adsorption holes arranged in upper and lower rows in a staggered manner, which optimizes airflow distribution. Meanwhile, the cover plate is provided with adsorption grooves corresponding to the adsorption holes and cover plate air inlets. The air suction connector connects the air suction device to form negative pressure and enhance the adsorption effect. In addition, grooves are designed on the first long side of the cover plate for installing cross glasses, which further improves the stability and rigidity of the clamping device. This design not only solves the shortcomings of traditional clamping devices in terms of adsorption force and stability, but also improves clamping efficiency and flexibility, achieving adsorption and transmission of large-size glass substrates.
