Description

Technical Field

[0001] This utility model belongs to the field of intelligent logistics technology, specifically relating to an intelligent logistics adaptive grasping device. Background Technology

[0002] Intelligent logistics utilizes integrated intelligent technologies to enable logistics systems to mimic human intelligence, possessing the ability to think, perceive, learn, reason, and solve certain problems in logistics independently. It is widely applied to basic activities in the logistics industry, such as transportation, warehousing, distribution, packaging, and loading and unloading, to achieve automated operation and highly efficient management of the express delivery process, improve the service level of the logistics industry, reduce costs, and decrease the consumption of natural and social resources.

[0003] In some existing logistics gripping trolleys, rigid boxed goods are typically gripped. These trolleys can withstand the clamping force of the equipment without deformation. Two gripping arms hold and move the parcels. Due to the weight difference between the parcels, the force borne by the gripping arms also varies. One end of the gripping arm is connected to the trolley, and the other end grips the parcel. Both ends are on the same horizontal line. Therefore, during frequent starts, stops, and speed changes, the logistics trolley needs to quickly lift, stop, or turn in the storage environment. The inertia of the parcel will generate a significant horizontal impact force. When the gripping arms hold the parcels, the damage to the connection between the gripping arms and the trolley is relatively large. The weight of the parcels being gripped and the weight of the gripping mechanism itself are transmitted to the connection between the gripping arms and the trolley through the gripping arms. The shear stress generated at the connection between the gripping arms and the trolley may cause structural deformation or breakage at the connection, resulting in equipment damage.

[0004] Therefore, this utility model provides an intelligent logistics adaptive gripping device that can adaptively adjust according to different heights of the connecting arm under load, thereby reducing shear stress. Utility Model Content

[0005] To address the problem of excessive load on the connecting arm under heavy load conditions in existing technologies, this utility model provides an intelligent logistics adaptive gripping device.

[0006] The present invention adopts the following technical solution: an intelligent logistics adaptive gripping device, comprising a support base and a set of connecting arms slidably connected thereto, wherein a diagonal bar is provided between the support base and the connecting arms;

[0007] The connecting arm includes a slanted groove that mates with the slanted rod. When the connecting arm carries the parcel box and moves up and down on the support under the drive of the drive structure, the slider that is movably connected to one end of the slanted rod slides in the slanted groove and adaptively adjusts according to the horizontal height of the connecting arm, so that the slanted rod always pulls the connecting arm, reducing stress concentration.

[0008] Preferably, the slider is slidably engaged with the inclined groove.

[0009] Preferably, the support base has a first sliding groove, and fixed shafts are fixedly connected to both sides of the upper end of the support base, with the diagonal rod rotatably connected to the fixed shafts.

[0010] Preferably, a lifting assembly is provided in the first slide groove. The lifting assembly includes a movable block and a screw that is rotatably connected to the support base. The screw passes through the movable block, and the movable block is slidably connected to the first slide groove.

[0011] Preferably, the two connecting arms are fixedly connected to both ends of the movable block.

[0012] Preferably, a clamping assembly is provided at the end of the connecting arm away from the movable block. The clamping assembly includes a second slide groove formed in the connecting arm, a clamping member slidably connected in the second slide groove, and an electric telescopic rod fixedly connected in the second slide groove. The telescopic end of the electric telescopic rod is fixedly connected to the clamping member.

[0013] Beneficial effects:

[0014] (1) The intelligent logistics adaptive gripping device described in this utility model uses a slanted bar and a slanted groove to decompose the horizontal force into a tangential force along the slanted groove and a pressure in the vertical direction through slanted constraint. The position of the slider is automatically adjusted according to the height change of the connecting arm. This decomposition greatly reduces the instantaneous shear stress at the connection between the connecting arm and the moving block, avoids structural deformation or breakage, and extends the service life of the structure.

[0015] (2) The intelligent logistics adaptive gripping device described in this utility model can suppress the shaking of the connecting arm during the lifting and lowering process under load by pulling the connecting arm with the diagonal bar, thereby improving the stability of the express box operation.

[0016] (3) The intelligent logistics adaptive gripping device described in this utility model reduces the number of supporting components and lowers the motor load of the equipment by using the combination of inclined bars and inclined grooves and optimizing the mechanical structure.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example: Figures 1-5 The intelligent logistics adaptive gripping device shown includes a support base 1 and a set of connecting arms 3 slidably connected thereto. A diagonal bar 5 is provided between the support base 1 and the connecting arms 3. The connecting arm 3 includes a sloping groove 31 that cooperates with the diagonal bar 5. When the connecting arm 3 carries the parcel box and moves up and down on the support base 1 under the drive of the drive structure, the slider 6 movably connected to one end of the diagonal bar 5 slides in the sloping groove 31 and is adaptively adjusted according to the horizontal height of the connecting arm 3, so that the diagonal bar 5 always pulls the connecting arm 3, reducing stress concentration.

[0025] In this embodiment, the bottom of the support base 1 is provided with rollers that allow the equipment to move. The control center drives the equipment to move to a designated position. The bottom of the screw 21 is provided with an electric device to drive the screw 21 to rotate, which drives the connecting arm 3 to the required height. The clamping assembly 4 is used to clamp and grab the express box and carry the express box to another designated position. When the connecting arm 3 moves up and down on the support base 1, the inclined rod 5 rotates around the fixed shaft 12. The slider 6 connected to the end of the inclined rod 5 away from the fixed shaft 12 slides in the inclined groove 31. The sliding is adaptive according to the horizontal height of the connecting arm 3, which reduces the stress at the connection between the connecting arm 3 and the movable block 22. The vertical pressure, bending moment and shear force borne by the connection between the connecting arm 3 and the movable block 22 are different depending on the load. The force can be decomposed and reduced by the cooperation of the inclined rod 5 and the inclined groove 31. When the connecting arm 3 is at different heights, the slider 6 slides in the inclined groove 31, and the inclined rod 5 always pulls the connecting arm 3, reducing the burden at the connection between the connecting arm 3 and the movable block 22.

[0026] Specifically, such as Figures 1-4As shown, slider 6 is slidably engaged with inclined groove 31; support base 1 has a first sliding groove 11, and fixed shafts 12 are fixedly connected to both sides of the upper end of support base 1, and inclined rod 5 is rotatably connected to fixed shafts 12; lifting assembly 2 is provided in the first sliding groove 11, lifting assembly 2 includes movable block 22 and screw 21 rotatably connected to support base 1, screw 21 passes through movable block 22, movable block 22 is slidably connected to first sliding groove 11; screw 21 rotates to drive movable block 22 to move, both ends of movable block 22 pass through first sliding groove 11 and extend to outside support base 1, maintaining the stability of movable block 22 when moving, the bottom width of inclined groove 31 is greater than the top width, and slider 6 is located at the bottom of inclined groove 31. The slider 6 is rotatably connected to the end of the inclined rod 5. When the movable block 22 drives the two connecting arms 3 to move, the slider 6 slides in the inclined groove 31. The higher the horizontal height of the connecting arm 3, the closer the slider 6 is to the end of the connecting arm 3 away from the movable block 22. Conversely, the lower the horizontal height of the connecting arm 3, the closer the slider 6 is to the end of the connecting arm 3 connected to the movable block 22. The sliding degree of the slider 6 is automatically adjusted according to the change in the height of the connecting arm 3. The length of the inclined rod 5 remains unchanged. When the slider 6 moves, the inclined rod 5 rotates around the fixed shaft 12 as the center, while the end away from the fixed shaft 12 always pulls the two connecting arms 3, reducing the shear stress and axial pressure at the connection between the connecting arm 3 and the movable block 22.

[0027] Specifically, such as Figure 2 and Figure 5 As shown, two connecting arms 3 are fixedly connected to both ends of the movable block 22 respectively; a clamping assembly 4 is provided at the end of the connecting arm 3 away from the movable block 22. The clamping assembly 4 includes a second slide groove 41 opened in the connecting arm 3, a clamping member 43 slidably connected in the second slide groove 41, and an electric telescopic rod 42 fixedly connected in the second slide groove 41. The telescopic end of the electric telescopic rod 42 is fixedly connected to the clamping member 43. After the device moves to the designated position, the screw 21 rotates, driving the movable block 22 and the connecting arm 3 to move to the required height. The distance between the ends of the two connecting arms 3 away from the movable block 22 is greater than the width of the parcel box that can be clamped. The parcel box is a rigid box that can withstand the clamping force of the clamping assembly 4 without deformation. The control device moves closer to the parcel box to be grabbed and places it on the two connecting arms. Between points 3, the electric telescopic rod 42 extends, pushing the clamping member 43 to slide out of the second slide groove 41. The two clamping members 43 approach each other until they contact the parcel box, clamping and fixing the parcel box. At this time, the movement of the equipment can drive the parcel box to move. The two symmetrically designed clamping members 43 generate clamping forces of equal magnitude and opposite direction under the action of the electric telescopic rod 42, so that the goods are in a static equilibrium state in the horizontal direction. At this time, the goods are only subjected to the normal pressure perpendicular to the clamping member 43, and the resultant force is zero, avoiding lateral sliding and achieving a two-way clamping mechanical balance. The clamping member 43 is equipped with a pressure sensor to detect the pressure value at each contact point, so that the clamping pressure value is within the range that the parcel box can bear. An anti-slip pad can be set on the side of the clamping member 43 near the parcel box to increase friction.

[0028] Working principle: During use, the lifting component 2 is controlled to make the movable block 22 drive the two connecting arms 3 to a suitable horizontal height. The rotation of the screw 21 can drive the movable block 22 to move. Then, the electric telescopic rod 42 is controlled to extend, so that the clamping part 43 slides out from the second slide groove 41. The two clamping parts 43, which are close to each other, clamp the express box from both sides and move it to another position. During the up and down movement of the connecting arm 3, the slider 6 slides in the inclined groove 31. The inclined rod 5 rotates around the fixed shaft 12 and automatically adjusts according to the change of the horizontal height of the connecting arm 3. The slider 6 slides within the range of the inclined groove 31, so that the inclined rod 5 always pulls the connecting arm 3, decomposes the shear stress at the connection between the connecting arm 3 and the movable block 22, extends the service life of the equipment, and reduces the shaking generated during the up and down movement of the connecting arm 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
