Description

Multipurpose flexible tongs

Technical Field

The utility model relates to a flexible gripper, in particular to a multipurpose flexible gripper.

Background

In the existing small production line, small or crisp and soft products or food can be realized only by a bionic octopus hand grip or a simple clamp, the former has high manufacturing cost, and the latter has inconvenient use and is easy to damage the products; in the existing automatic production line of small precision products or food and medicines, the carrying and moving of the small products generally have high requirements, in order to realize the functions, a bionic octopus gripper imported from abroad is generally adopted to realize the functions, the use cost is high, and in order to solve the problems, the utility model designs a multipurpose flexible gripper.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a multipurpose flexible gripper, which solves the moving and carrying problems of small-sized precise products, food and medicines.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the multipurpose flexible gripper comprises a clamping finger, a main body, a quick-insertion air pipe joint, a hinge point and a polymer film pipe, wherein the main body is provided with a plurality of clamping fingers, the movable joint of the clamping finger is provided with the hinge point, the joint of the clamping finger is provided with a through hole, the through hole is filled with the polymer film pipe, the polymer film pipe is connected with a three-position five-way electromagnetic valve through the quick-insertion air pipe joint on the main body, and the three-position five-way electromagnetic valve is further connected with an air path of a vacuum generator and an air supply system.

Preferably, the clamping finger comprises three sections of finger main bodies, the three sections of finger main bodies are connected through two movable joints, and the movable joints are connected through rivets.

The utility model has the beneficial effects that:

the multipurpose flexible gripper is reasonable in structural design, and capable of greatly reducing the expensive manufacturing cost of the conventional bionic octopus gripper while ensuring the practicability, freeing manpower, reducing the working cost of enterprises, improving the working efficiency and increasing the enterprise benefits.

Drawings

The utility model is described in detail below with reference to the drawings and the detailed description;

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a released state of the gripping fingers according to the present invention;

fig. 3 is a schematic view of the grabbing state of the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: the flexible tongs of multipurpose, press from both sides and get finger 1 including pressing from both sides, main part 2, insert the trachea joint 3 soon, hinge point 4 and polymer film pipe 5, it gets finger 1 to be provided with a plurality of clamps on the main part 2, it is provided with hinge point 4 to press from both sides the freely movable joint department of getting finger 1, the joint department of getting finger 1 of pressing from both sides is provided with the through hole, the through hole intussuseption is filled with polymer film pipe 5, polymer film pipe 5 is connected with three-position five-way solenoid valve through inserting trachea joint 3 soon on the main part 2, three-position five-way solenoid valve still is connected with vacuum generator gas circuit and air feed system.

It is worth noting that the clamping finger 1 comprises three sections of finger main bodies, the three sections of finger main bodies are connected through two movable joints, and the movable joints are connected through rivets.

The working principle of the embodiment is as follows:

1. the flexible gripper can flexibly customize gripping finger materials of different materials according to different products, and has material selection with higher sanitary standard aiming at food and medicine industries;

2. the standard type of the fingers of the hand grip is generally designed into 2 movable joints and three sections of finger bodies, the maximum opening and closing angle of a single section of finger is 40 degrees, and the finger joints are connected by rivets, so that the hand grip is convenient and quick and is easy to replace;

3. the finger activity power uses compressed air as a power source, a through hole is formed in a finger joint, a polymer film is used as an air inflation bag body to be filled in the through hole, when the compressed air is pressed into a polymer film bag body, the bag body expands to force fingers to bend towards the opposite direction, a 3-position 5-way electromagnetic valve is selected for control in the aspect of air supply, the situation that air is cut off and the fingers cannot loosen during grasping is ensured, a workpiece cannot be damaged, when a gripper is released, the electromagnetic valve is communicated with an air path of a vacuum generator, the polymer film bag body is contracted through vacuum extraction, the fingers expand along the contraction direction of the bag body, and the workpiece is put down at the same time;

4. because the air pressure tolerance of the high polymer film capsule body can only bear within 0.2Mpa, the fingers can adapt to the appearance of the workpiece under the clamping condition without damaging the workpiece.

On the premise of ensuring the use convenience, the embodiment reduces the cost as much as possible and improves the economic benefit of enterprises.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
