[0002] The top layer of stacked materials (such as printed packages) tends to be tilted. When the material is picked up by the negative pressure suction cup, there is an angle between the surface of the negative pressure suction cup and the surface of the material, which makes it impossible to form a vacuum environment between the negative pressure suction cup and the material, thus affecting the suction cup's ability to pick up the material.

[0023] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 2 As shown, this embodiment provides a material handling device 100, including a suction component 10, a first lifting component 20, and a clamping mechanism 30.

[0025] For ease of reading, this application introduces the terms first direction Z, second direction X, and third direction Y to describe the embodiments of this application. The first direction Z, second direction X, and third direction Y can be three non-parallel straight lines in space; further, the first direction Z, second direction X, and third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Y as the Y-axis direction of the three-dimensional coordinate system.

[0026] The suction member 10 is configured to suck up material and is capable of elastic deformation. Along the first direction Z, a first lifting assembly 20 is spaced above the material to be sucked up. The first lifting assembly 20 is drive-connected to the suction member 10 to drive the suction member 10 towards or away from the material along the first direction Z. When the first lifting assembly 20 drives the suction member 10 towards the material, the suction member 10 can abut against the material and undergo elastic deformation, so that the suction surface P1 of the suction member 10 is in contact with the material's surface to be sucked up, P2. Along the first direction Z, the surface of the suction member 10 facing the material is designated as the suction surface P1, and the surface of the material facing the suction member 10 is designated as the surface to be sucked up, P2. The material can be a single piece or multiple pieces stacked together, with the suction member 10 sucking up the material at the top. A clamping mechanism 30 is configured to clamp the material sucked up by the suction member 10.

[0027] Thus, in the material handling device 100 of this application, the suction member 10 is configured to be elastically deformable. When the first lifting component 20 drives the suction member 10 to move and abut against the material to be picked up surface P2, the suction member 10 can undergo elastic deformation to adapt to the material to be picked up surface P2 based on the inclined state of the material to be picked up surface P2, thereby making the suction surface P1 and the surface of the material to be picked up surface P2 fit together, ensuring the smooth progress of the material picking operation.

[0028] Please combine Figure 1 In one embodiment, the first lifting assembly 20 includes a first lifting drive 21 and a first lifting plate 22. The first lifting drive 21 is tractively connected to the first lifting plate 22 and is used to drive the first lifting plate 22 to move along a first direction Z. The suction member 10 is connected to the first lifting plate 22.

[0029] In this embodiment, the material handling device 100 further includes a material handling seat 40. A first lifting drive 21 is mounted on the material handling seat 40. The first lifting drive 21 is a drive device such as a cylinder that can drive the first lifting plate 22 to move up and down along the first direction Z. Its specific structure is not limited in this application.

[0030] The number of suction components 10 is set to at least two, and at least two suction components 10 are connected to the side of the first lifting plate 22 near the material. Along the second direction X, at least two suction components 10 are arranged sequentially at intervals so that the material can be sucked up by multiple suction components 10 at the same time, which can improve the stability of the material picking and placing process.

[0031] Please combine Figure 1 and Figure 2 In one embodiment, the suction member 10 is an accordion suction cup, and the suction member 10 includes an elastic part 11 and a suction nozzle part 12. The suction nozzle part 12 is connected to one end of the elastic part 11, and the suction nozzle part 12 is configured to suck up material. The elastic part 11 can be elastically bent to adjust the posture of the suction nozzle part 12.

[0032] The elastic part 11 is a hollow pipe structure, roughly shaped like an accordion. It consists of multiple sub-parts connected sequentially along the first direction Z, and all sub-parts are interconnected. The cross-sectional shape of each sub-part is approximately hexagonal. When the suction nozzle 12 abuts against the material, the elastic part 11 is compressed and bent, causing the suction nozzle 12 to deflect and thus adapt to the material's suction surface P2. The suction component 10 used in this application can adapt to a suction surface P2 with an inclination angle of approximately ±20°.

[0033] Furthermore, the surface of the end of the suction nozzle 12 away from the elastic part 11 is designated as the suction surface P1, and a plurality of air holes 120 are provided on the suction surface P1. The plurality of air holes 120 can be arranged in a ring array, and the diameter of the air holes 120 is approximately 1 mm, so as to ensure that when the suction nozzle 12 sucks up flexible materials, the surface of the material will not have wrinkles or marks.

[0034] The elastic part 11 has an air passage 110 inside. One end of the air passage 110 is connected to a plurality of air holes 120, and the other end of the air passage 110 is connected to a vacuum generator so as to create a negative pressure environment by simultaneously evacuating air from the plurality of air holes 120 through the vacuum generator.

[0035] Please combine Figure 3 In one embodiment, the clamping mechanism 30 includes a second lifting assembly 31 and a clamping assembly 32. The clamping assembly 32 is configured to clamp material, and the second lifting assembly 31 is drively connected to the clamping assembly 32 for driving the clamping assembly 32 to move along a first direction Z.

[0036] In this embodiment, the second lifting assembly 31 includes a second lifting drive 311 and two second lifting plates 312. The second lifting drive 311 is tractively connected to the two second lifting plates 312 and is used to drive the two second lifting plates 312 to move along the first direction Z.

[0037] Two second lifting plates 312 are slidably connected to the material-receiving seat 40. The second lifting drive component 311 is a driving device such as a cylinder, and the second lifting drive component 311 is installed on the material-receiving seat 40. There are two second lifting drive components 311, and the two second lifting drive components 311 are respectively connected to the two second lifting plates 312 so that the two second lifting plates 312 can be moved independently by the two second lifting drive components 311.

[0038] Furthermore, the clamping assembly 32 includes two clamping drive members 321 and two clamping members 322. The two clamping drive members 321 are respectively connected to the two second lifting plates 312, and the two clamping members 322 are rotatably connected to the bottom ends of the two second lifting plates 312. The two clamping drive members 321 and the two clamping members 322 are correspondingly arranged, and the clamping drive members 321 are drively connected to their corresponding clamping members 322 to drive the clamping members 322 to rotate.

[0039] The first end of the clamping member 322 is drivenly connected to the clamping drive member 321, and the second end of the clamping member 322 is configured to abut and support the material. The middle section of the clamping member 322 is rotatably connected to the second lifting plate 312. The clamping drive member 321 is a driving device such as a cylinder, and the clamping drive member 321 is configured to drive the first end to move along the first direction Z, so that the middle section of the clamping member 322 rotates relative to the second lifting plate 312, thereby deflecting the second end of the clamping member 322, and thus clamping the material through the second ends of the two clamping members 322.

[0040] Specifically, along the second direction X, the clamping drive member 321 is mounted on one side of the second lifting plate 312, and two mounting protrusions are provided on the other side of the second lifting plate 312. Along the third direction Y, the two mounting protrusions are spaced apart. The clamping assembly 32 also includes a rotating shaft 323, which is connected to the middle section of the clamping member 322. The extending direction of the rotating shaft 323 is parallel to the third direction Y, and the rotating shaft 323 is located between the two mounting protrusions, with both ends of the rotating shaft 323 rotatably connected to the two mounting protrusions.

[0041] The clamping member 322 includes a first clamping part 3221 and a second clamping part 3222, which are inclined together. A through hole 3120 is provided on the second lifting plate 312, extending through the second lifting plate 312 along the second direction X. One end of the first clamping part 3221 passes through the through hole 3120 and is connected to the driving end of the clamping drive member 321. The second clamping part 3222 is connected to the other end of the first clamping part 3221. A rotating shaft 323 passes through the connection between the first clamping part 3221 and the second clamping part 3222 along the third direction Y. The second clamping part 3222 has a supporting protrusion 32220 at one end away from the first clamping part 3221. The supporting protrusion 32220 extends from the surface of the second clamping part 3222 near the material towards the material side, so that the supporting protrusion 32220 and the second clamping part 3222 are inclined. Thus, when the second clamping parts 3222 of the two clamping members 322 clamp the material from both sides in the second direction X, the supporting protrusions 32220 of the two clamping members 322 abut against the bottom surface of the material to support the material, further ensuring the stability of the material being sucked by the suction member 10 during movement.

[0042] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
