Description

Technical Field

[0001] The utility model relates to the technical field of material handling devices, in particular to a special suction cup for sucking flat glass. Background Art

[0002] Flat glass is widely used in modern industry and life, and the requirements for its handling and stacking efficiency and safety are becoming increasingly higher. Traditional flat glass suction devices usually use vacuum suction cups, which achieve suction by forming negative pressure between the suction cups and the glass. However, the suction cups in the prior art have some shortcomings, especially in some special cases, such as when the glass surface is coated with anti-mildew powder or a suction cup cover is used, the performance of the suction cup will be affected.

[0003] First, traditional suction cups, such as accordion suction cups and thick lip suction cups, usually have a large cavity volume, which means that it takes a long time to establish sufficient vacuum during the adsorption process, thereby reducing the handling efficiency. In addition, the larger cavity volume also increases the volume and weight of the suction cup, which is not conducive to the miniaturization and lightweight of the equipment. Secondly, some existing suction cups have thicker lips. Although they can provide stronger adsorption force, the thick lips are more easily worn during repeated use, which shortens the service life of the suction cup and increases the maintenance cost. Especially when there is anti-mildew powder on the glass surface or when a suction cup cover is used, the thick lips are more susceptible to wear and damage. In addition, due to the unevenness of the glass surface and the possible tilting during handling, it is difficult for traditional suction cups to always maintain the best contact state during adsorption. This may lead to insufficient adsorption force and even cause the glass to fall off, posing a safety hazard.

[0004] Therefore, there is an urgent need for a novel suction cup specifically for sucking flat glass, which can overcome the shortcomings of the prior art, improve handling efficiency and safety, and extend the service life of the suction cup. Summary of the invention

[0007] Further, the sucker body includes a disk body, a base body, and an air passage that penetrates the base body and communicates with the negative pressure chamber. The disk body is made of a deformable material, and the base body is assembled with the disk body as a whole; the hollow connecting rod is movably connected to the base body and communicates with the air passage, so that the hollow connecting rod can rotate relative to the sucker body.

Detailed implementation manners

[0020] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Embodiment 1

[0022] As Figures 1 to 4 shown, the special suction cup for flat glass described in this embodiment includes a hollow connecting rod 10 and a suction cup body 20 forming a negative pressure chamber. A sealing lip 30 is provided at the edge of the mouth of the suction cup body 20. The sealing lip 30 is composed of at least three concentric annular sealing lips 31, and the thickness of each annular sealing lip 31 gradually decreases towards the side away from the suction cup body 10; one end of the hollow connecting rod 10 is communicated with the negative pressure chamber of the suction cup body 20, and the other end is used to connect an external vacuum generating device (not shown in the figure); the hollow connecting rod 10 is movably connected to the suction cup body 20, so that the hollow connecting rod 10 and the suction cup body 20 can rotate relative to each other.

[0023] In specific implementation, for example, in the glass handling scenario, the suction cup is installed at the end of the robotic arm and connected to a vacuum generating device through a hollow connecting rod 10. When the robotic arm manipulates the suction cup body 20 to approach the glass plate, due to the special design of the sealing lip edge 30 - the thickness of each concentric ring-shaped sealing lip 31 gradually decreases from the inside to the outside, the outermost sealing lip edge first contacts the glass surface in a line contact manner. This line contact design can ensure that the suction cup quickly and tightly adheres to the glass and rapidly establishes a vacuum to achieve a firm adsorption even in the case of slight unevenness, anti-mold powder, or other fine particles on the glass surface. At the same time, when the robotic arm is handling the glass plate, if the glass plate tilts, the movable connection between the hollow connecting rod 10 and the suction cup body 20 will allow the suction cup to automatically adjust the angle and always maintain the best contact state with the glass plate, avoiding the weakening of the adsorption force or the detachment of the glass plate, thus significantly improving the safety of handling.

[0024] In some embodiments, such as Figure 2 、 Figure 3 shown, the suction cup body 20 includes a disk body 21, a base body 22, and an air passage 23 that penetrates the base body 22 and communicates with the negative pressure chamber. The disk body 21 is made of a deformable material, and the base body 22 is assembled with the disk body 21 as a whole; the hollow connecting rod 10 is movably connected to the base body 22 and communicates with the air passage 23, so that the hollow connecting rod 10 can rotate relative to the suction cup body 20. In this embodiment, since the disk body 21 is made of a deformable material, it can undergo slight deformation during the adsorption process, thereby filling in the small irregularities on the glass surface, increasing the contact area, and improving the adsorption force. The base body 22 is usually made of a relatively strong material and can withstand greater pressure and deformation. Its movable connection with the hollow connecting rod 10 and the cooperation of the air passage 23 enable the base body 22 and the disk body 21 to rotate together relative to the hollow connecting rod 10, thus realizing the universal adjustment function of the suction cup.

[0025] In this embodiment, as Figure 2 、 Figure 3 shown, the hollow connecting rod 10 includes a hemispherical connecting end 11 configured to be movably connected to the base body 22, and a seal 40 disposed between the hemispherical connecting end 11 and the base body 22 and communicating with the air passage 23. The seal 40 allows the hollow connecting rod 10 to rotate relative to the base body 22 and maintains the seal. In this way, the design of the hemispherical connecting end 11 allows for a larger rotation angle between the hollow connecting rod 10 and the base body 22, so that the suction cup can adapt to a larger range of glass plate tilts and unevenness. The seal 40 is disposed between the hemispherical connecting end 11 and the base body 22, and even when the hollow connecting rod 10 and the base body 22 rotate relative to each other, the seal 40 can maintain good sealing performance, thus ensuring that the suction cup can stably adsorb the glass plate.

[0026] In some embodiments, as Figure 3 shown, on the opposite surfaces of the hemispherical connecting end 11 and the base body 22, there is a sealing groove 50 communicating with the air passage 23, and the sealing member 40 is an annular sealing ring arranged in the sealing groove 50; an annular deformation groove 41 is provided on the outer periphery of the annular sealing ring, and the inner diameter of the annular sealing ring is greater than the inner diameter of the tube of the hollow connecting rod 10. The sealing groove 50 accommodates the annular sealing ring 40, providing a tightly fitting sealing surface, effectively reducing vacuum leakage. The annular deformation groove 41 on the outer periphery of the annular sealing ring allows the sealing ring to deform flexibly when the hollow connecting rod 10 rotates, so as to effectively reduce friction and wear while maintaining good sealing performance. In addition, the inner diameter of the annular sealing ring is greater than the inner diameter of the tube of the hollow connecting rod 10, and this design provides greater rotational space support for the hollow connecting rod 10, that is, at a larger rotation angle, the sealing ring can also ensure that the hollow connecting rod 10 is always docked and communicated with the air passage 23, avoiding air leakage, so as to maintain stable vacuum adsorption.

[0027] In some embodiments, as Figure 2 、 Figure 3 shown, a filter screen 25 fixed by a C-shaped circlip 24 is provided in the air passage 23. The filter screen 25 can effectively block dust, particulate matter and other impurities from entering the air passage 23 and the vacuum system, thereby protecting the vacuum pump and pipeline and extending their service life; the C-shaped circlip 24 enables the filter screen 25 to be quickly disassembled and assembled without complex tools, reducing the maintenance cost and time.

[0028] In some embodiments, as Figure 2 、 Figure 3 shown, a plurality of equally spaced and distributed upright columns 211 are provided on the inner surface of the disc body 21, and the height of the upright columns 211 is less than the depth of the disc body 21. The presence of the upright columns 211 can effectively prevent the disc body 21 from being overly deformed or collapsed under negative pressure, thereby maintaining the shape and adsorption stability of the suction cup. In addition, the presence of the upright columns 211 can reduce the air volume inside the suction cup, thereby accelerating the speed of vacuum establishment and improving the working efficiency of the suction cup.

[0029] In some embodiments, as Figure 1 、 Figure 3 shown, it further includes a hoop 26; the base body 22 is provided with an annular protrusion 221, the disc body 21 is provided with a buckle groove matching with the annular protrusion 221, and the buckle groove is tightly fixed to the annular protrusion 221 by the hoop 26. The annular protrusion 221 cooperates with the buckle groove to ensure the accurate positioning and assembly of the disc body 21 and the base body 22 as a whole, and the hoop 26 can firmly connect the disc body 21 and the base body 22 together, ensuring that the two will not separate or have relative displacement during the working process, and can maintain the connection stability even under the action of a large suction force or external impact.

[0030] In some embodiments, such as Figure 4 shown, each of the annular sealing lips 31 includes a first inclined surface 311 extending toward the center of the suction cup body 20 and a second inclined surface 312 forming an acute angle with the first inclined surface 311. With this structural design, when the suction cup approaches the glass surface, first, the thin edge of the second inclined surface 312 contacts the glass, and then as the suction cup continues to descend, the first inclined surface 311 gradually fits the glass surface, forming a progressive contact to better adapt to the minute unevenness or particulate matter (such as mold-proof powder) on the glass surface, enhance the sealing performance by gradually increasing the contact area, minimize air leakage to the greatest extent, and ultimately improve the adsorption force. In addition, even if there are fine dust or protrusions on the glass surface, the suction cup can gradually eliminate the interference through this progressive contact and finally achieve a tight seal.

[0031] The special suction cup for flat glass provided in this embodiment adopts a multi-channel sealing lip design and contacts the glass surface in a line contact manner. Even in the presence of mold-proof powder or a suction cup sleeve, it can ensure a tight fit, quickly establish a vacuum, and maintain a stable adsorption force. At the same time, the movable connection between the hollow connecting rod and the suction cup body endows the suction cup with the ability to automatically adjust the angle, enabling it to adapt to the unevenness of the glass surface and the inclination during the handling process, thereby improving the reliability and safety of adsorption and effectively preventing the glass from falling off.
