[0052] Figure 1 2 is a schematic structural diagram of a suction device 100 according to one embodiment of the present disclosure. Figure 2 2 is a schematic structural diagram of the suction device 100 from another angle according to an embodiment of the present disclosure. Figure 3 It is a structural schematic diagram of a partial structure of a suction device according to one embodiment of the present disclosure.

[0053] like Figures 1 to 3 As shown, the suction device 100 of the present disclosure may include components such as a mounting plate 110 , a first suction assembly 120 , and a second suction assembly 130 .

[0054] When the suction device 100 of the present disclosure is in use, the mounting plate 110 can be fixed to the end of a robotic arm, so that the robotic arm drives and moves the suction device 100 to a preset position to achieve suction of materials.

[0055] For the convenience of description, Figure 1 As shown, a horizontal direction can be defined according to the mounting plate 110 of the present disclosure. That is, the mounting plate 110 of the present disclosure is formed into a plate-like structure and is disposed substantially horizontally.

[0056] The first suction assembly 120 is disposed on the mounting plate 110, and the first type of product is sucked by the first suction assembly 120. The first type of product has a certain thickness, for example, it can be a box-type product.

[0057] Specifically, the first suction assembly 120 of the present disclosure may include: a first drive assembly 121 and a sponge suction cup 122; wherein the first drive assembly 121 of the present disclosure is fixed to the mounting plate 110. In a preferred embodiment, a vertical plate 140 is provided on the mounting plate 110, wherein the vertical plate 140 is arranged substantially vertically, and the majority of the vertical plate 140 is located above the mounting plate 110. In this case, the first drive assembly 121 can be fixed to the vertical plate 140 and is used to drive the sponge suction cup 122 to reciprocate along a first direction, which is the vertical direction.

[0058] That is to say, when the first driving component 121 of the present invention moves, it can drive the sponge suction cup 122 to move downward and absorb the product; when the sponge suction cup 122 completes product absorption, the first driving component 121 drives the sponge suction cup 122 to move upward, and under the action of the robotic arm, moves the product to a preset position.

[0059] In a preferred embodiment, the first suction assembly 120 includes two slide cylinders arranged in series. Thus, when both slide cylinders are extended, the first suction assembly 120 has a larger travel range. Furthermore, when one of the two slide cylinders is actuated, the sponge suction cup 122 can be stopped at a position intermediate between the initial position and the maximum position. In particular, when the two slide cylinders have different travel ranges, the sponge suction cup 122 will have two intermediate positions, which undoubtedly facilitates the sponge suction cup 122 to absorb the product. More preferably, the slide cylinder can be a pressure-adjustable slide cylinder.

[0060] In the present disclosure, the suction device 100 further includes a distance detection device 150 for detecting the thickness of the product to be sucked. Thus, when the suction device 100 of the present disclosure is in operation, it can determine the permissible overpressure distance when the sponge suction cup 122 is sucking the product based on the thickness of the product to be sucked. Furthermore, during the process of the sponge suction cup 122 sucking the product, the distance detection device 150 can also detect the position of the sponge suction cup 122 and components such as a tool or tray holding the product, thereby determining the overpressure distance of the sponge suction cup 122 and preventing the sponge suction cup 122 from applying excessive pressure to the product and damaging the product.

[0061] In a preferred embodiment, the distance detection device 150 is an ultrasonic sensor. Of course, the distance detection device 150 of the present disclosure can also be a laser sensor or the like.

[0062] In the present disclosure, the second suction assembly 130 is disposed on the mounting plate 110, and the second type of product is sucked by the second suction assembly 130. Specifically, the second type of product in the present disclosure may be a label, which is significantly thinner than the first type of product.

[0063] In a preferred embodiment, the second suction assembly 130 of the present disclosure can be provided in multiple configurations, with the multiple second suction assemblies 130 located on the same side of the first suction assembly 120. More preferably, the sponge suction cup 122 of the present disclosure is cylindrical, meaning that a cross-section of the sponge suction cup 122 can be circular. These second suction assemblies 130 can be evenly spaced along a radial direction of the sponge suction cup. Thus, the suction device of the present disclosure can suck up multiple labels at once, improving the suction device's loading efficiency.

[0064] Specifically, if Figure 1 and Figure 2 As shown, in the suction device of the present disclosure, two second suction assemblies 130 can be provided.

[0065] The second suction assembly 130 may include a second drive assembly 131 and a vacuum suction cup 133. The second drive assembly 131 is connected to the mounting plate 110 and is connected to the vacuum suction cup 133 via a floating assembly 132. The second drive assembly 131 is configured to drive the vacuum suction cup 133 to reciprocate in a first direction. In one embodiment, the vacuum suction cup 133 is a label suction plate, capable of sucking a label.

[0066] In addition, the second driving component 131 of the present invention can be a slide cylinder, the extension and retraction direction of the slide cylinder is the vertical direction, so that the vacuum suction cup 133 of the present invention can generate a lifting movement in the vertical direction under the drive of the second driving component 131.

[0067] Refer again Figure 1 and Figure 2 In the present disclosure, the floating assembly 132 may include components such as a fixed plate 132A, a sliding rod 132B, and a spring 132C.

[0068] The fixing plate 132A is fixed to the second driving assembly 131. Specifically, the fixing plate 132A of the present disclosure is formed as a plate-shaped member and is disposed substantially horizontally; and the fixing plate 132A of the present disclosure is formed in a rectangular shape and has four corners.

[0069] The fixing plate 132A is provided with two through holes, specifically, the two through holes are respectively located approximately in the middle of the short sides of the fixing plate 132A. A linear bearing 132E is provided in the through holes.

[0070] Sliding rod 132B is slidably disposed within linear bearing 132E, and the lower end of sliding rod 132B is fixedly connected to vacuum suction cup 133. A limiter 132D is provided at the upper end of sliding rod 132B. Limiter 132D and linear bearing 132E limit the maximum downward displacement of sliding rod 132B. In the present disclosure, limiter 132D may be an external flange formed at the upper end of sliding rod 132B.

[0071] The vacuum cup 133 of the present disclosure is disposed substantially parallel to the fixing plate 132A. The vacuum cup 133 is also formed in a rectangular shape and has substantially the same cross-sectional area as that of the fixing plate 132A.

[0072] The spring 132C is arranged between the fixed plate 132A and the vacuum suction cup 133, and the spring 132C is in a pre-compressed state. Therefore, when the vacuum suction cup 133 of the present invention absorbs the label, it can apply positive pressure to the label. The reaction force of the positive pressure will make the vacuum suction cup 133 approach the fixed plate 132A. At this time, the spring 132C is in an energy storage state, thereby making the vacuum suction cup 133 have a certain elasticity.

[0073] In a preferred embodiment, four springs 132C may be provided, and the four springs 132C are respectively provided at the four corners of the fixing plate 132A and the vacuum suction cup 133 , so that the vacuum suction cup 133 is more stable during movement.

[0074] In the present disclosure, four upper accommodating grooves are provided on the lower surface of the fixed plate 132A, and a rod component 132F is installed on the bottom wall of the upper accommodating groove, wherein the upper end of the spring 132C is sleeved on the rod component 132F and is located in the upper accommodating groove; and, four lower accommodating grooves are provided on the upper surface of the vacuum suction cup 133, and the lower end of the spring 132C can be located in the lower accommodating groove, so that the spring 132C can be stably set between the fixed plate 132A and the vacuum suction cup 133.

[0075] Therefore, the suction device disclosed in the present invention can absorb multiple products of different thicknesses when used, solving the technical problems mentioned in the background technology. Therefore, the use of the suction device disclosed in the present invention can replace manual handling and improve loading efficiency.
