[0030] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] As shown in Figures 1-4 The carton transporting holder provided by the embodiment of the present application comprises a top plate 100, a clamping plate assembly, a vacuum suction cup 500, a double-sided rack 900 and a clamping arm assembly. A central area on the top of the top plate 100 is fixedly provided with a connecting piece 110, which is perpendicular to the top of the top plate 100. The top plate 100 is connected to corresponding driving devices and production lines through the connecting piece 110. The transporting holder can form a structure similar to a mechanical hand through the driving of corresponding devices, thereby facilitating the clamping and transporting of cartons.

[0032] The clamping plate assembly comprises two side plates 200 symmetrically arranged on both sides of the top plate 100. The outer surface of each side plate 200 is fixedly provided with a hydraulic cylinder 300. The piston rod of the hydraulic cylinder 300 penetrates the side plate 200 along the thickness direction and extends to the vicinity of the inner surface of the side plate 200. The end of the piston rod of the hydraulic cylinder 300 is fixedly connected to an I-shaped clamping plate 400, and the I-shaped clamping plate 400 is located at the side of the inner surface of the side plate 200. In actual operation, a shunt valve is arranged on the transporting holder to control the action of the hydraulic cylinders 300 at both side plates 200 at the same time, and the I-shaped clamping plates 400 located at both sides can move towards each other or away from each other. The shunt valve is a common device in the hydraulic system to realize the speed synchronization of two execution elements, which will not be described in detail in this embodiment.

[0033] In addition, the four corner areas of the I-shaped clamping plate 400 are also fixedly provided with vacuum suction cups 500. When the I-shaped clamping plates 400 located at both sides move towards each other, the I-shaped clamping plates 400 can realize the function of pre-adsorbing and fixing the carton through the vacuum suction cups 500.

[0034] In the embodiment, the surface of the I-shaped clamping plate 400 located at both sides is also provided with two groups of four clamping arm assemblies. Each group comprises two clamping arm assemblies arranged on the surface of the I-shaped clamping plate 400 at the same side. Each clamping arm assembly comprises a supporting plate 600 fixedly arranged on the inner surface of the side plate 200. The supporting plate 600 is perpendicular to the inner surface of the side plate 200 and is distributed in the horizontal direction. The supporting plate 600 penetrates the I-shaped clamping plate 400 along the thickness direction and extends to the side of the I-shaped clamping plate 400, and the supporting plate 600 and the I-shaped clamping plate 400 are in a sliding connection relationship.

[0035] As shown in Figure 3 andFigure 4 As shown, the surface of the pallet 600 is also provided with two clamping arms 700 through the rotation axis, each of which can rotate relative to the pallet 600 along the rotation axis. Specifically, the rotating end of each clamping arm 700 is provided with a profile gear 800, which is part of a complete gear. The profile gears 800 of the two clamping arms 700 are also meshingly connected with a double-sided rack 900, which is fixedly connected with the I-shaped clamping plate 400. Therefore, when the I-shaped clamping plate 400 is driven to move by the piston rod of the hydraulic cylinder 300, the double-sided rack 900 will move accordingly and drive the double-sided rack 900 to change from the unfolded state to the tightened clamping state through meshing, thereby realizing the secondary clamping function of the carton.

[0036] The working process of the carton transport holder provided by the embodiment of the present application will be described below.

[0037] The transport holder is moved to the carton stack through a corresponding driving device or production line. When the I-shaped clamping plate 400 moves towards each other through the piston rod of the hydraulic cylinder 300, the vacuum suction cup 500 first adsorbs and fixes on the outer surface of the carton to realize preliminary adsorption and fixation. At the same time, during the movement of the I-shaped clamping plate 400, the double-sided rack 900 moves synchronously with the I-shaped clamping plate 400 and is driven by the profile gear 800 to drive the clamping arm 700 to gradually change from the open state to the tightened state synchronously, thereby forming secondary distributed mechanical clamping on the side surface of the carton. Thus, each group of clamping arm assemblies can clamp a single carton, and the cartons on the same side and the cartons on the opposite side are in mutual abutting relationship, that is, a single holder can simultaneously clamp and transport four batch cartons in a cross shape.

[0038] At this time, the piston rods of the hydraulic cylinders 300 on both sides reach the maximum stroke, and the rubber clamping layer 710 of the clamping arm 700 is fully abutted with the carton to ensure the dynamic balance of the rigid contact of the clamping system and the flexible adsorption of the vacuum suction cup 500. The above structure design makes the clamping force evenly distributed between the contact area of the vacuum suction cup 500 area and the clamping arm 700, thereby ensuring the clamping effect while effectively avoiding the appearance of indentation damage on the surface of the carton.

[0039] Preferably, the end of the double-sided rack 900 is also fixedly provided with a slide bar 1000, and the width of the slide bar 1000 is greater than the width of the double-sided rack 900. When the slide bar 1000 is in contact with the profile gear, the profile gear 800 enters the self-locking area, the clamping arm 700 reaches the maximum clamping angle, and the rubber clamping layer 710 of the clamping arm 700 is fully abutted with the carton to ensure the rigid contact of the clamping arm assembly and the carton.

[0040] In some embodiments, the vacuum chuck 500 is a rubber vacuum chuck 500, and the suction surface is provided with anti-skid texture. The rubber vacuum chuck 500 has excellent elastic deformation capability, which can adapt to the slight concave-convex surface of the carton, thereby enhancing the sealing of the suction. Moreover, the anti-skid texture can increase the friction coefficient between the suction surface and the carton surface, so as to prevent inertial sliding of the carton due to the smooth surface of the carton during high-speed transportation.

[0041] In some embodiments, the length of the outward extension of the vacuum chuck 500 is equal to the length of the clamping arm 700, and the center line of the vacuum chuck 500 coincides with the projection of the clamping point at the end of the clamping arm 700. In this way, the spatial positions of the suction point and the mechanical clamping point are consistent, thereby forming a cooperative clamping force together, so as to avoid the inclination or sliding of the carton due to uneven force.

[0042] In some embodiments, the clamping arm assemblies on the same side of the I-shaped clamping plate 400 are in an up-down staggered relationship, and the vertical distance between the two is 1 / 3-1 / 2 of the height of the clamped carton. With this structural design, the mutual abrasion of the clamping arms 700 on the same side can be avoided.

[0043] In some embodiments, the inner side of the clamping end of the clamping arm 700 is provided with a rubber layer 710, and specifically, the rubber layer 710 is provided with a dovetail groove, and the inner side of the clamping arm 700 is provided with an aluminum alloy base, and the two are detachably connected by interference fit. The rubber layer 710 can provide flexible contact for mechanical clamping, so as to prevent the carton surface from being broken. Moreover, the detachable design can facilitate replacement of the rubber layer 710 with greater abrasion.

[0044] In some embodiments, the upper part of the supporting plate 600 is further fixedly provided with a protective cover, which covers the meshing area of the odd-shaped gear and the double-sided gear rack 900. In this way, foreign matters such as paper scraps and dust outside can be prevented from entering the gear transmission structure, thereby avoiding the problems of jamming and abrasion. At the same time, the protective cover can also have the effect of sound insulation, thereby reducing the noise of mechanical transmission. In addition, it can also avoid the safety hazards caused by accidental touch of the operator.
