Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Traditional adsorption components typically consist of multiple spaced-apart adsorption holes, which securely hold the workpiece by adsorbing different parts of it. However, when the adsorption component adsorbs a workpiece with a warped surface, gaps form between the adsorption holes and the workpiece surface, compromising the integrity of the vacuum seal, reducing the adsorption force, and causing the workpiece to easily fall off during handling or processing.

[0036] Therefore, some embodiments of this utility model propose an adsorption component 1000, which is applied to a workpiece 2000 with a warped surface, such as glass with an uneven surface, as detailed below. Figures 1 to 8 The adsorption component 1000 is described below.

[0037] Reference Figure 1 and Figure 5 As shown in this embodiment of the invention, the adsorption assembly 1000 includes a main body 100, which includes an interconnected mounting portion 110 and two extension portions 120. For example, the mounting portion 110 and the extension portions 120 may be integrally formed. The mounting portion 110 has an internal airflow channel 111 communicating with a vacuum generator, and the surface of the mounting portion 110 has a first adsorption hole 410 communicating with the airflow channel 111. Therefore, the first adsorption hole 410 is indirectly connected to the vacuum generator. When the vacuum generator is activated, the first adsorption hole 410 can generate an adsorption force to adsorb the workpiece 2000.

[0038] Reference Figure 1 and Figure 2 As shown, in this embodiment of the present invention, two extensions 120 are spaced apart on both sides of the first adsorption hole 410 along the width direction of the mounting portion 110. In this embodiment, the two extensions 120 are symmetrically arranged. The end face of the extension 120 on the same side as the first adsorption hole 410 is a contact surface 121, which is inclined to contact the warped surface of the workpiece 2000. For example, with... Figure 2 Taking workpiece 2000 as an example, both ends of workpiece 2000 are warped upwards, while the middle part is at its lowest position. Based on this, the mating surface 121 on the left side is tilted to the right, and conversely, the mating surface 121 on the right side is tilted to the left, so as to fit against the warped ends of workpiece 2000.

[0039] Reference Figure 1 As shown, in this embodiment of the present invention, the bonding surface 121 is provided with a second adsorption hole 510 communicating with the airflow channel 111. In one example, the second adsorption hole 510 can be formed on the surface of the bonding surface 121. It is understood that, since the bonding surface 121 is inclined, the opening of the second adsorption hole 510 can also be inclined in this embodiment, thereby more closely adhering to the surface of the workpiece 2000. Along the length direction of the mounting portion 110, the first adsorption hole 410 and the second adsorption hole 510 are staggered. The second adsorption hole 510 is located on one side of the first adsorption hole 410 along the length direction of the mounting portion 110. For example, the two second adsorption holes 510 and the first adsorption hole 410 can form a triangle, realizing multi-point adsorption of the workpiece 2000, thereby dispersing the adsorption force and improving the stability of adsorption.

[0040] Reference Figure 2 As shown, in this embodiment of the invention, the two opposite ends of the workpiece 2000 are bent in the same direction to form a U-shaped structure. Based on this, in this embodiment, the bonding surface 121 is offset away from the second adsorption hole 510 along its direction toward the other bonding surface 121. Continuing... Figure 2 Taking workpiece 2000 as an example, it can be understood that the bonding surface 121 on the left side is offset downwards from left to right, and conversely, the bonding surface 121 on the right side is offset downwards from right to left, so that the two bonding surfaces 121 are respectively bonded to the two bent ends of workpiece 2000. Therefore, the first adsorption hole 410 can adsorb the middle part of workpiece 2000, that is, the position of workpiece 2000 that is relatively closer to adsorption component 1000, and the two second adsorption holes 510 can adsorb the two bent ends of workpiece 2000 one by one.

[0041] Understandably, the inventors discovered during numerous experiments that when the inclination angle of the mating surface 121 in the width direction of the mounting portion 110 is too small, it becomes difficult for the mating surface 121 to fully adhere to the warped surface of the workpiece 2000, and the gap between the second adsorption hole 510 and the surface of the workpiece 2000 increases. When the inclination angle of the mating surface 121 in the width direction of the mounting portion 110 is too large, it becomes difficult for the workpiece 2000 mounted on the mating surface 121 to maintain contact with the mating surface 121, and their relative positions easily change. Based on this, referring to... Figure 4 and Figure 6 As shown in this embodiment of the invention, the inclination angle α of the mating surface 121 in the width direction of the mounting portion 110 satisfies: 0.5°≤α≤10°. Therefore, by reasonably designing the range of the inclination angle α, it is possible to ensure that the mating surface 121 can fully fit against the warped surface of the workpiece 2000 while maintaining the relative position between the mating surface 121 and the warped surface of the workpiece 2000.

[0042] Understandably, once the adsorption force of the first adsorption hole 410 and the second adsorption hole 510 is released, the workpiece 2000 will quickly detach from the adsorption assembly 1000 due to the loss of support and the influence of the reaction force, easily causing the workpiece 2000 to fall and be damaged. Therefore, referring to... Figure 4 and Figure 3 As shown in the embodiment of this utility model, the adsorption component 1000 further includes a limiting plate 200, which is located on the same side as the contact surface 121. The limiting plate 200 and the contact surface 121 are arranged opposite to each other, and the shape and size of the limiting plate 200 match those of the two extensions 120.

[0043] Specifically, refer to Figure 3As shown in this embodiment of the invention, one end of the limiting plate 200 is connected to the mounting portion 110, and the other end is spaced apart from the contact surface 121, defining a receiving groove 300 for accommodating the workpiece 2000. The size of the receiving groove 300 matches the workpiece 2000, and its opening faces away from the mounting portion 110. When it is necessary to adsorb the workpiece 2000, the workpiece 2000 can be inserted into the receiving groove 300 first, and then the workpiece 2000 in the receiving groove 300 can be adsorbed through the first adsorption hole 410 and the second adsorption hole 510. When the adsorption force of the first adsorption hole 410 and the second adsorption hole 510 is released, the limiting plate 200 can restrict the workpiece 2000 from moving away from the adsorption assembly 1000, thereby reducing the risk of it falling out of the receiving groove 300.

[0044] Continue to refer to Figure 3 As shown in this embodiment of the invention, the limiting plate 200 includes a connecting portion 210 and two abutting portions 220 connected to each other. The connecting portion 210 is located on the side of the first adsorption hole 410 away from the second adsorption hole 510, thus preventing the connecting portion 210 from obstructing the first adsorption hole 410. The connecting portion 210 is connected to the mounting portion 110. It should be noted that the connecting portion 210 and the mounting portion 110 can be connected by welding, bonding, or other fastening methods. This embodiment does not limit this. Along the thickness direction of the mounting portion 110, the two abutting portions 220 and the two extension portions 120 are spaced apart to form a gap for the workpiece 2000 to pass through.

[0045] Understandably, the inventors discovered during numerous experiments that when the minimum width of the receiving groove 300 is too small, the workpiece 2000 inserted into the receiving groove 300 will be squeezed by the limiting plate 200, increasing the risk of damage to the workpiece 2000. When the minimum width of the receiving groove 300 is too large, the constraint effect of the limiting plate 200 on the workpiece 2000 will be weakened, and the workpiece 2000 will have excessive movement space, causing it to move too fast and easily collide with the limiting plate 200, thus causing damage. Therefore, referring to... Figure 6 As shown, in this embodiment of the present invention, the minimum width of the receiving groove 300 along the thickness direction of the mounting portion 110 is W, satisfying: 0.4 mm ≤ W ≤ 1 mm. It should be noted that in this embodiment, the minimum width of the receiving groove 300 can be the distance between the limiting plate 200 and the end of the mating surface 121 closest to the limiting plate 200. Therefore, by reasonably designing the range of W, it is possible to ensure that the workpiece 2000 can be easily inserted into the receiving groove 300 while providing sufficient limiting effect on the workpiece 2000, thus reducing the displacement amplitude of the workpiece 2000.

[0046] Reference Figure 7 and Figure 8As shown, in this embodiment of the present invention, the mounting portion 110 is provided with a first groove 112, and the contact surface 121 is provided with a second groove 122. The first groove 112 and the second groove 122 are respectively connected to the airflow channel 111. The adsorption assembly 1000 also includes a first elastic element 400 and a second elastic element 500. A first adsorption hole 410 is formed in the first elastic element 400, and the first elastic element 400 is press-fitted with the first groove 112. A second adsorption hole 510 is formed in the second elastic element 500, and the second elastic element 500 is press-fitted with the second groove 122. The arrangement of the first elastic element 400 and the second elastic element 500 makes the contact surface between the adsorption assembly 1000 and the workpiece 2000 more flexible, reducing the risk of damaging the workpiece 2000. In one example, the first groove 112 and the second groove 122 are both circular grooves, and the first elastic element 400 and the second elastic element 500 are both annular rubber parts.

[0047] Continue to refer to Figure 7 and Figure 8 As shown in this embodiment of the invention, the end face of the first elastic member 400 facing away from the mounting portion 110 is connected to the inner wall of the first adsorption hole 410 by a rounded transition surface, and the end face of the second elastic member 500 facing away from the extension portion 120 is connected to the inner wall of the second adsorption hole 510 by a rounded transition surface. This helps to improve the sealing performance of the first adsorption hole 410 and the second adsorption hole 510, thereby improving the adsorption effect and enhancing the adsorption stability.

[0048] Understandably, the inventors discovered during numerous experiments that when the distance between the holes of the two second adsorption holes 510 is too small, the two second adsorption holes 510 are insufficient to fully adsorb the bent ends of the workpiece 2000. When the distance between the holes of the two second adsorption holes 510 is too large, the middle region of the workpiece 2000 lacks sufficient support. Therefore, referring to... Figure 4 As shown, in this embodiment of the invention, the distance between the shafts of the two second adsorption holes 510 is L, which satisfies: 50mm ≤ L ≤ 70mm. Therefore, by reasonably designing the range of L, the two second adsorption holes 510 can fully adsorb the bent ends of the workpiece 2000 while ensuring that the middle area of ​​the workpiece 2000 receives sufficient support.

[0049] An embodiment of this utility model also proposes a conveying device, including a moving device, a vacuum generating device, and the adsorption component 1000 of the above embodiment. The moving device is connected to the adsorption component 1000 and is used to drive the adsorption component 1000 to move. The vacuum generating device is connected to the airflow channel 111.

[0050] It is understood that the handling device of this utility model embodiment adopts the adsorption component 1000 of the above embodiment. By providing a first adsorption hole 410 on the surface of the mounting part 110 and a second adsorption hole 510 on the contact surface 121 in the extension part 120, wherein the first adsorption hole 410 and the second adsorption hole 510 are staggered along the length direction of the mounting part 110, multi-point adsorption of the workpiece 2000 is achieved, thereby enhancing the stability of adsorption. Furthermore, by tilting the contact surface 121 so that it can be attached to the warped surface of the workpiece 2000, a tight fit between the second adsorption hole 510 and the warped surface of the workpiece 2000 is ensured, effectively avoiding sealing problems caused by gaps, achieving stable adsorption of the warped workpiece 2000, improving the stability of the adsorption force, reducing the risk of the workpiece 2000 falling during handling or processing, and improving the reliability and stability of the handling equipment.

[0051] Since the conveying device adopts all the technical solutions of the adsorption component 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
