Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material handling, and in particular relates to a wire drum clamp for a truss robot. Background Art
[0002] Wire drum materials are mainly found in the cable industry and the steel industry. The weight of this type of material is generally as small as 6, 7 or 8 kilograms, and as large as 2 or 3 tons. At present, in actual production, most of them are transported manually by forklifts or cranes. A small number of companies have upgraded their logistics automation and used equipment such as truss robots and AGVs. The most common ways to grab materials are: C-type hooks, forklifts, L-type hooks, forks, etc. C-type hooks are mostly used for manual lifting based on cranes, while L-type hooks and forks are mostly used in automated logistics systems.
[0003] However, C-type hooks and L-type hooks take up too much space during use. When grabbing workpieces, C-type hooks and L-type hooks are inserted into the center hole of the wire reel from one side. Therefore, the space occupied by using C-type hooks and L-type hooks is at least the width of a wire reel. At the same time, using L-type hooks will not only cause the above problems, but also cause the equipment to bear unbalanced loads, which has high requirements on the equipment structure. Forks and forklifts are both under-support type clamps, which are mainly installed on ground equipment such as AGVs, and especially on aerial equipment such as truss robots. They are mostly used in stacker-based and truss-based three-dimensional warehouses. In logistics turnover, this type of clamp will not only occupy the space on one side of the wire reel, but also occupy the space under the wire reel. At the same time, there are certain requirements for the pallet structure under the wire reel, which not only reduces the space utilization but also increases the cost and structural complexity. Utility Model Content
[0004] The purpose of the utility model is to solve the defects and shortcomings in the prior art and to design a wire drum clamp for a truss robot which is compact in structure, stable and reliable, convenient and effective, improves material turnover efficiency, and is efficient and safe.

[0006] Preferably, the two hook claws are symmetrically arranged below the base, and the hook claws are slidably matched with a slide rail fixed on the bottom surface of the base through a slider.
[0007] Preferably, at least two Z-axis buffer pad supports are arranged above the base, and the Z-axis buffer pad supports are used to install the Z-axis buffer pad.
[0008] Preferably, the driving mechanism comprises two groups of cylinder assemblies respectively connected to two hooks, the cylinder assembly comprises a cylinder body and a solenoid valve for driving the cylinder body, and the cylinder body piston rod is connected to the hook via a floating joint.

[0010] Preferably, both ends of the base are further provided with limit blocks, and the two hook claws are provided with buffer blocks matching the limit blocks on the sides away from each other.
[0011] Preferably, the buffer pad and the buffer block are both made of rubber.
[0012] After adopting the above technical solution, the wire drum clamp for a truss robot provided by the utility model has the following beneficial effects:

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0021] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0023] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0024] The utility model discloses a wire drum clamp for a truss robot, such as Figure 1-3 As shown, it includes a base 1, two hooks 2 slidably arranged on the base 1, and a driving mechanism for driving the two hooks 2 to move toward or oppositely to achieve a grasping or releasing action. The two hooks 2 are provided with a positioning pin 3 and a buffer pad 4 on the opposite sides. The positioning pin 3 matches the center holes 6 on the left and right sides of the wire drum 5. Through the design of the positioning pin 4 and the two hooks 2 clamping structure, the stability of the material during operation is increased, the safety of material handling is improved, and a higher operating speed is supported. Specifically, on the one hand, the positioning pin 4 can limit the four degrees of freedom of the wire drum 5 and bear the entire weight of the wire drum 5. On the other hand, the clamping mechanism limits the other two degrees of freedom of the wire drum 5 through the extrusion force and the friction force of the contact surface buffer pad 4, thereby achieving complete positioning of the wire drum 5.
[0025] Among them, the two hook claws 2 are symmetrically arranged below the base 1, and the hook claws 2 slide with the slide rail 8 fixed on the bottom surface of the base 1 through the slider 7 to ensure a good clamping and guiding function. At least two Z-axis buffer pad supports 9 are arranged above the base 1, and the Z-axis buffer pad supports 9 are used to install the Z-axis buffer pad 10 to play a buffering role in the Z-axis direction.
[0026] The driving mechanism includes two groups of cylinder assemblies respectively connected to the two hooks 2, and the cylinder assembly includes a cylinder body 11 and a solenoid valve 12 for driving the cylinder body 11. The P port of the solenoid valve 12 is connected to the air source, the A port is connected to the rear air port of the cylinder body 11, and the B port is connected to the front air port of the cylinder body 11. The piston rod of the cylinder body 11 is connected to the hook 2 through a floating joint 13. The cylinder body 11 is also connected to an in-position sensor 14 and a speed regulating valve 15. Limit blocks 16 are also provided at both ends of the base 1. The two hooks 2 are each provided with a buffer block 17 matching the limit block 16 on one side away from each other, so as to provide a limit buffering effect when the two hooks 2 move away from each other. The buffer pad 4 and the buffer block 17 are both made of rubber.
[0027] When a wire reel clamp for a truss robot is in operation, a control signal is given by the truss control system, a solenoid valve 12 is actuated, a cylinder body 11 works, and two hook claws 2 are driven to move toward each other to clamp the wire reel 5. After the action is completed, the truss control system reads the state of a position sensor 14 of the cylinder body 11, and the truss robot starts the carrying action after receiving the position signal of the cylinder position sensor 14.
[0028] When the utility model places the wire reel, the truss control system gives a signal to open the clamp, the solenoid valve 12 is actuated, the cylinder body 11 works, and the two hook claws 2 are driven to move in opposite directions, so as to open and separate the positioning pins 3 from the center holes 6 on both sides of the wire reel 5. After the action is completed, the truss control system reads the state of the in-position sensor 14. When the in-position signal of the cylinder in-position sensor 14 is received, the truss robot is lifted and leaves the wire reel 5 placement station to prepare for or start a new cycle.
[0029] To sum up, the wire reel clamp for a truss robot provided by the utility model increases the stability of materials during operation, improves the safety of material handling, and supports higher operating speeds. It has the advantages of compact structure, stability and reliability, convenience and effectiveness, and improves material turnover efficiency. It is efficient and safe, has great market value, and deserves wide promotion and application.
