[0001] The utility model relates to the technical field of arm elastic suction heads, and particularly relates to a robotic arm elastic suction head. Background Technique

[0002] An elastic suction head is a special end effector used in industrial robots and automated equipment. It grabs and releases objects through an elastic suction cup or suction pad, and is especially suitable for items with smooth or irregular surfaces. The main feature of this suction head is its elastic suction ability, which can grab various objects without damage, and has self - adaptability, capable of automatically adjusting the suction angle and force according to the curvature and unevenness of the object surface. In addition, the control system of the suction head can flexibly control the magnitude of the suction force by adjusting air pressure or vacuum degree to adapt to objects of different weights and materials. Elastic suction heads are widely used in fields such as electronic product assembly, food processing, medical device manufacturing, and logistics warehousing.

However, there are still some deficiencies in traditional elastic suction heads. For example, the position of its installation components is relatively fixed, so it is difficult to make adaptive adjustments when facing robotic arms of different specifications, resulting in certain limitations during installation. In addition, the structure of its elastic suction pad is relatively fixed, so it is difficult to replace it in time when the elastic suction pad is damaged, thus affecting its grasping and releasing effect. Therefore, a robotic arm elastic suction head is proposed to solve the above - mentioned problems. Summary of the Invention

[0026] Please refer to Figure 1-8 , the present utility model provides a technical solution:

[0027] A robotic arm elastic adsorption head, comprising a connection support 1. Below the connection support 1, an adsorption support 2 with a matching specification is provided. At both ends of the center of the inner cavity of the top wall of the connection support 1, adjustment grooves 3 are symmetrically opened, and adjustment components 4 are arranged in the adjustment grooves 3. At both ends of the center of the top of the connection support 1, mounting components 5 are symmetrically provided. At the center of the top of the connection support 1, a communication component 6 is provided. On both bottom sides of the connection support 1 and on both top sides of the adsorption support 2, a plurality of connection components 7 are arranged at equal intervals. The bottom of the adsorption support 2 is fixedly connected with a wavy elastic adsorption pad 8.

[0028] The adjusting assembly 4 includes an adjusting screw 401. One end of the adjusting screw 401 is rotatably connected to the inner side wall of the adjusting groove 3, and the other end extends to the outside of the connecting support 1 and is fixedly connected with an adjusting dial 402 at this end. An adjusting block 403 that is slidably connected to the adjusting groove 3 is penetrated and threadedly connected to the adjusting screw 401. The adjusting assembly 4 can flexibly adjust the position of the mounting assembly 5 according to the actual installation conditions. Therefore, it can be adaptively adjusted when facing robotic arms of different specifications, so that there will be no limitations during installation; The mounting assembly 5 includes a mounting post 501 fixedly connected to the top of the adjusting block 403. The top of the mounting post 501 is fixedly connected with a mounting plate 502. Mounting bolts 503 penetrate symmetrically through the left and right ends of the mounting plate 502. The mounting assembly 5 can fixedly connect the connecting support 1 with the end of the robotic arm to ensure the overall stability; The connecting assembly 6 includes a connecting pipe 601 penetrating through the center of the top wall of the connecting support 1. A connecting flange 602 is fixedly sleeved on the top end of the connecting pipe 601. A number of connecting bolts 603 penetrate through and are arranged at equal intervals on the connecting flange 602. The connecting assembly 6 can connect the connecting support 1 with a vacuum source, so as to provide an adsorption force through the vacuum source; The connecting component 7 includes sealing inserts 701 fixedly connected to the bottom of both side walls of the connecting support 1. An elastic clamping plate 702 is provided at the bottom of the sealing insert 701. A connecting bolt 703 is fixedly connected to the center of the bottom of the sealing insert 701, and a connecting screw hole 704 matching the specification of the connecting bolt 703 is opened at the center of the top of the elastic clamping plate 702. The connecting component 7 further includes sealing slots 705 opened at equal intervals on the top of both side walls of the adsorption support 2. The sealing slots 705, the sealing inserts 701 and the elastic clamping plates 702 are arranged with equal numbers, corresponding positions and matching specifications. A positioning bolt 706 penetrates through the outer side wall of the sealing slot 705, and a positioning screw hole 707 corresponding to the position and matching the specification of the positioning bolt 706 is opened on the same side wall of the sealing insert 701. The connecting component 7 can provide good connection strength between the connecting support 1 and the adsorption support 2. Therefore, not only can a vacuum chamber be formed between the inner cavities of the connecting support 1 and the adsorption support 2 to facilitate the grasping and releasing of objects, but also it can be disassembled. Therefore, when the elastic adsorption pad 8 is damaged, it can be replaced in time to avoid affecting its grasping and releasing effect.

[0029] Workflow: First, power on all electrical appliances and connect external controllers to each electrical appliance. The connecting support 1 can provide support and an installation foundation for the whole. The adsorption support 2 can fixedly support the elastic adsorption pad 8. The adjustment groove 3 can provide an installation space for the adjustment component 4. The adjustment component 4 can flexibly adjust the position of the installation component 5 according to the actual installation conditions. Therefore, it can be adaptively adjusted when facing robotic arms of different specifications, so that there will be no limitations during installation. During adjustment, rotate the adjustment dial 402 to drive the adjustment screw 401 to rotate, and at the same time drive the adjustment block 403 to slide in the adjustment groove 3, thereby driving the installation component 5 to adjust its position. The installation component 5 can fixedly connect the connecting support 1 to the end of the robotic arm to ensure the overall stability. After the position of the installation component 5 is adjusted, fit the installation support plate 502 on the installation pillar 501 to the end of the robotic arm, and then screw in the installation bolt 503 at the end of the robotic arm. The connection component 6 can connect the connecting support 1 to the vacuum source, so as to provide adsorption force through the vacuum source. When connecting to the vacuum source, fit the connection flange 602 to the output end of the vacuum source, and then screw in the connection bolt 603 at the output end of the vacuum source to connect the connection pipe 601 to the vacuum source. The connection component 7 can provide good connection strength between the connecting support 1 and the adsorption support 2. Therefore, not only can a vacuum chamber be formed between the inner cavities of the connecting support 1 and the adsorption support 2 for grasping and releasing objects, but also it can be disassembled. Therefore, when the elastic adsorption pad 8 is damaged, it can be replaced in time to avoid affecting its grasping and releasing effect. When connecting the connecting support 1 and the adsorption support 2, first place the connecting support 1 above the adsorption support 2, and then move it down until the sealing plug 701 and the elastic clamping plate 702 are inserted into the sealing slot 705. The connection between the connecting support 1 and the adsorption support 2 is positioned by the clamping of the sealing plug 701 and the elastic clamping plate 702 with the sealing slot 705. At this time, the positioning screw hole 707 corresponds to the hole position of the positioning bolt 706. Finally, just screw the positioning bolt 706 into the positioning screw hole 707. At this time, a vacuum chamber is formed between the inner cavities of the connecting support 1 and the adsorption support 2. The vacuum source evacuates to make the vacuum chamber generate negative pressure, firmly adsorbing the object on the elastic adsorption pad 8. The elastic material and wavy shape of the elastic adsorption pad 8 can maintain good sealing even on uneven surfaces. When the elastic adsorption pad 8 is damaged and the adsorption support 2 needs to be disassembled and replaced, it is the same reason. Also, because the elastic clamping plate 702 and the sealing plug 701 are screwed together through the connecting bolt 703 and the connecting screw hole 704, it is convenient to replace the elastic clamping plate 702 when the elastic force of the elastic clamping plate 702 decreases or it is damaged and affects the clamping effect, without replacing the sealing plug 701 together, so as to reduce the later maintenance cost.
