[0002] When products are packed into packaging boxes, a flipping device is needed to flip the top and bottom of the boxes delivered from the production line. Currently, most of these flipping devices directly use negative pressure nozzles to suction the top and bottom of the boxes and drive them to flip. However, the top and bottom of the boxes are prone to shifting during the flipping process, which can affect subsequent product packaging operations. Utility Model Content

[0005] In one possible implementation, the clamping member includes a first clamping portion and a second clamping portion, wherein the extension direction of the first clamping portion is parallel to a second direction, the second direction intersects the first direction, and the two first clamping portions are configured to clamp the workpiece.

[0006] The second clamping part is disposed along the first direction, the second clamping part is connected to the first clamping part, and the second clamping part is configured to support the workpiece.

[0007] In one possible implementation, the clamping member has a defined alignment posture and the clamping posture;

[0008] The alignment posture is set as follows: the first clamping part partially abuts against the workpiece and the second clamping part is away from the workpiece.

[0009] The clamping posture is set such that the first clamping part is attached to the surface of the workpiece and the second clamping part supports the workpiece.

[0010] In one possible implementation, the clamping assembly further includes an elastic element, one end of which is elastically connected to the clamping member to provide an elastic force to the clamping member, the elastic force being configured to maintain the clamping member in the alignment posture.

[0011] In one possible implementation, the clamping assembly further includes a rotating shaft, the clamping member being rotatably connected to the sliding member via the rotating shaft, and the elastic members being spaced apart on the side of the rotating shaft near the adsorption assembly along the second direction.

[0017] The clamping structure of this application uses an adsorption component to pick up the workpiece and two sliding members to drive two clamping members to move and clamp the workpiece picked up by the adsorption component. The clamping members can rotate relative to the sliding members. When the adsorption component is adsorbing the workpiece, the clamping members can rotate to a non-clamping posture to avoid affecting the adsorption operation of the adsorption component. When the adsorption component completes the adsorption operation, the clamping members can rotate to a clamping posture. Thus, while the two clamping members are clamping the workpiece, they can also support the clamped workpiece, ensuring the stability of the workpiece after it is adsorbed by the adsorption component and ensuring that the workpiece will not shift during subsequent flipping operations.

[0029] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Furthermore, unless expressly defined herein, terms such as those defined in a general dictionary should be interpreted as having the same meaning as they have in the relevant art and in the content of this application, and will not be interpreted as having an idealized or overly formal meaning.

[0030] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 As shown, this embodiment provides a clamping structure 100, including a substrate 10, an adsorption component 20, and a clamping component 30.

[0032] For ease of reading, this application introduces a first direction X, a second direction Z, and a third direction Y to describe the embodiments of this application. The first direction X, the second direction Z, and the third direction Y can be three non-parallel straight lines in space; further, the first direction X, the second direction Z, and the 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 X is described as the X-axis direction of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the three-dimensional coordinate system.

[0033] The adsorption assembly 20 is connected to the substrate 10 and is configured to pick up the workpiece 40. The clamping assembly 30 includes a sliding drive 31 and two sliding members 32, which are slidably connected to the substrate 10 along a first direction X. The sliding drive 31 drives the two sliding members 32 to move them closer or further apart. Each of the two sliding members 32 is provided with a clamping member 33, which is rotatable relative to the sliding members 32 to be in a clamping posture. The clamping posture is such that part of the clamping member 33 abuts against the workpiece 40 and part of the clamping member 33 supports the workpiece 40.

[0034] Thus, the clamping structure 100 of this application uses the adsorption component 20 to pick up the workpiece 40, and the two sliding members 32 respectively drive the two clamping members 33 to move, thereby clamping the workpiece 40 picked up by the adsorption component 20. The clamping members 33 can rotate relative to the sliding members 32. When the adsorption component 20 adsorbs the workpiece 40, the clamping members 33 can rotate to a non-clamping posture to avoid affecting the adsorption operation of the adsorption component 20. When the adsorption component 20 completes the adsorption operation, the clamping members 33 can rotate to a clamping posture. Thus, while the two clamping members 33 clamp the workpiece 40, they can also support the clamped workpiece 40, ensuring the stability of the workpiece 40 after it is adsorbed by the adsorption component 20, and ensuring that the workpiece 40 will not shift during subsequent flipping operations.

[0035] Please combine Figures 1 to 4 In one embodiment, along a third direction Y, a sliding drive member 31 is mounted on one side of a substrate 10, and two slide rails 11 are provided on the other side of the substrate 10, with the sliding drive member 31 located between the two slide rails 11. Along a first direction X, the two slide rails 11 are spaced apart, and the extension directions of both slide rails 11 are parallel to the first direction X. A sliding groove 3210 is provided on the sliding member 32, and the slide rails 11 slide in cooperation with the sliding groove 3210, allowing the sliding member 32 to slide along the sliding groove 3210.

[0036] An opening 12 is provided on the substrate 10. The driving end of the sliding drive member 31 passes through the opening 12 and is connected to two sliding members 32 to drive the two sliding members 32 to slide synchronously in opposite directions. The sliding drive member 31 can be a bidirectional cylinder or two independently set cylinders. The specific structure of the sliding drive member 31 can be selected according to the actual design requirements.

[0037] Furthermore, the cross-sectional shape of the slider 32 is approximately "L"-shaped. The slider 32 includes a first sliding portion 321 and a second sliding portion 322. The first sliding portion 321 is disposed along a first direction X, and one end of the first sliding portion 321 is connected to the driving end of the sliding drive member 31. A groove 3210 is formed on the first sliding portion 321. The second sliding portion 322 is disposed along a third direction Y, and the second sliding portion 322 is connected to the other end of the first sliding portion 321. The clamping member 33 is rotatably connected to the end of the second sliding portion 322 away from the first sliding portion 321.

[0038] In particular, the first sliding part 321 and the second sliding part 322 can be integrally formed or detachably connected by fasteners such as bolts.

[0039] Please combine Figures 1 to 4In one embodiment, the clamping member 33 has an approximately "L" shaped cross-section and includes a first clamping portion 331 and a second clamping portion 332. The first clamping portion 331 extends parallel to the second direction Z, and the first clamping portions 331 of the two clamping members 33 are respectively connected to adjacent sides of the two second sliding portions 322, so as to clamp the workpiece 40 by the adjacent movement of the two first clamping portions 331.

[0040] The second clamping portion 332 is disposed along the first direction X, and one end of the second clamping portion 332 is connected to the bottom end of the first clamping portion 331. Along the first direction X, the other end of the second clamping portion 332 extends beyond the first clamping portion 331, so as to support the workpiece 40 through the portion of the second clamping portion 332 that extends beyond the first clamping portion 331. The second clamping portion 332 can support the workpiece 40 that has been picked up by the adsorption assembly 20, and can also support the workpiece 40 that is not picked up.

[0041] In this embodiment, the clamping member 33 has a defined alignment posture and a clamping posture. The alignment posture is set such that the first clamping part 331 partially abuts against the workpiece 40 and the second clamping part 332 is away from the workpiece 40, so as to avoid the second clamping part 332 being located in the path of the adsorption component 20 to pick up the workpiece 40 and thus affecting the picking up of the workpiece 40. The clamping posture is set such that the first clamping part 331 is in contact with the surface of the workpiece 40 and the second clamping part 332 supports the workpiece 40, so that the workpiece 40 is clamped by the two first clamping parts 331 and supported by the two second clamping parts 332, thereby ensuring the stability of the workpiece 40 picked up by the adsorption component 20.

[0042] The clamping assembly 30 also includes a rotating shaft 34. The clamping member 33 is rotatably connected to the sliding member 32 via the rotating shaft 34 to switch the clamping member 33 between an alignment posture and a clamping posture. An extension 333 protrudes from the side of the first clamping part 331 near the second sliding part 322. A through hole 3330 is formed on the extension 333, extending through the extension 333 along a third direction Y. The rotating shaft 34 passes through the through hole 3330, with both ends of the rotating shaft 34 exposed outside the through hole 3330. The two ends of the rotating shaft 34 exposed outside the through hole 3330 are rotatably connected to the second sliding part 322.

[0043] Please combine Figures 1 to 4 In one embodiment, the clamping assembly 30 further includes an elastic member 35, one end of which is elastically connected to the clamping member 33 to provide an elastic force to the clamping member 33, the elastic force being configured to keep the clamping member 33 in an aligned position.

[0044] Along the first direction X, a first clamping portion 331 and a second sliding portion 322 are spaced apart, and an elastic member 35 is located between the first clamping portion 331 and the second sliding portion 322. The elastic member 35 is arranged along the first direction X, with one end elastically connected to the first clamping portion 331 and the other end elastically connected to the second sliding portion 322. Two elastic members 35 are provided, spaced apart along the third direction Y.

[0045] Along the second direction Z, elastic members 35 are spaced apart on the side of the rotating shaft 34 near the adsorption assembly 20. The elastic member 35 is a compression spring, which provides elastic force to the first clamping part 331 to drive the end of the first clamping part 331 away from the second clamping part 332 to tilt toward the workpiece 40 being picked up by the adsorption assembly 20.

[0046] Thus, before the adsorption assembly 20 picks up the workpiece 40, the two clamping members 33 are far apart, and the workpiece 40 can enter the space between the two clamping members 33 and be picked up by the adsorption assembly 20. At this time, the first clamping part 331 tilts towards one side of the workpiece 40 under the action of the elastic force of the elastic member 35. After the adsorption assembly 20 picks up the workpiece 40, the two sliding members 32 drive the two clamping members 33 to move closer to each other, and the workpiece 40 abuts against the first clamping part 331, causing the first clamping part 331 to overcome the elastic force of the elastic member 35 and deflect away from the workpiece 40 until the first clamping part 331 is deflected to a vertical state. At this time, the second clamping part 332 rotates to abut against the bottom surface of the workpiece 40 and supports the workpiece 40.

[0047] Please combine Figure 5 And see Figure 2 In one embodiment, the clamping assembly 30 further includes a support 36 detachably connected to the clamping assembly 33, the support 36 being configured to support the workpiece 40.

[0048] The support member 36 is arranged along the third direction Y. One end of the support member 36 is detachably connected to the bottom end face of the clamping member 33, and the other end of the support member 36 extends toward the side of the clamping member 33 away from the substrate 10, so that the workpiece 40 is supported by the support member 36 and the second clamping part 332, thereby further improving the stability of the workpiece 40 during the suction process.

[0049] Furthermore, along the third direction Y, the support member 36 can move relative to the clamping member 33 to adjust the distance between the support member 36 and the second clamping part 332, thereby adjusting the position of the support member 36 based on the different lengths of the workpiece 40 in the third direction Y.

[0050] Specifically, the clamping member 33 has multiple first connecting holes 334 arranged at intervals along the third direction Y. The support member 36 has multiple second connecting holes 360 arranged at intervals along the third direction Y. The first connecting holes 334 and the second connecting holes 360 allow fasteners such as bolts to pass through, thereby connecting the support member 36 and the clamping member 33. In addition, when the support member 36 slides to different positions relative to the clamping member 33, both have holes for fasteners to pass through and connect the two.

[0051] Please combine Figure 6 In one embodiment, the adsorption assembly 20 includes a suction plate 21 and an adsorption member 23. The suction plate 21 is disposed along a third direction Y, and one end of the suction plate 21 is connected to the top surface of the substrate 10. The suction plate 21 is provided with an air channel 210, which extends through the suction plate 21 along a second direction Z. The adsorption member 23 is configured to pick up the workpiece 40, and the adsorption member 23 is connected to one end of the air channel 210, while the other end of the air channel 210 is connected to a vacuum generator 22.

[0052] The adsorption element 23 can be a suction cup or similar structure. There are four adsorption elements 23, which are arranged in a rectangular array on the bottom surface of the suction plate 21. The vacuum generating device 22 evacuates the adsorption elements 23 through the air passage 210 to enable the adsorption elements 23 to pick up the workpiece 40.

[0053] like Figure 7 As shown, this embodiment also provides a flipping device 200, including a flipping drive 50 and the aforementioned clamping structure 100. The flipping drive 50 is connected to the substrate 10 of the clamping structure 100 for driving the substrate 10 to flip.

[0054] Along the third direction Y, the flipping drive 50 is located on the side of the substrate 10 away from the clamping member 33. The flipping drive 50 can be a drive device such as a rotary cylinder. The drive end of the flipping drive 50 is connected to the substrate 10 and can drive the substrate 10 to flip 180°.

[0055] 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.
