Problems solved by technology

However, such flexible robotic fingers are still not suitable for gripping tiny items, such as jewelry.
In addition, the current use of flexible finger gripping is not suitable for home use, and additional positive and negative pressure air sources are required to drive, which is inconvenient to use

Embodiment 1

[0036] Such as Figure 1 to Figure 6 As shown, a new type of flexible collet includes a clamping part 1 and a connecting part 2 made of elastic material, and the elastic material can be made of silicon rubber.

[0037] The clamping part 1 includes at least two fingertips 11 that cooperate with each other for clamping. Preferably, the number of the fingertips 11 is two to four, and each fingertip 11 has the same shape. Finger gaps 12 are formed between the fingertips 11, and a finger cavity 13 is provided inside each fingertip 11. The connecting portion 2 includes a communication chamber 21, which communicates with each finger cavity 13, The connection part 2 is provided with a communication port 23 communicating with the communication chamber 21. The fingertip 11 includes an inner wall 14 close to the finger crevice 12 and an outer wall 15 far away from the finger crevice 12. The thickness of the inner wall 14 is smaller than that of the outer wall 15. The thickness or the el...

Embodiment 2

[0043] This embodiment discloses a new type of flexible clamp, which uses the flexible chuck in Embodiment 1, such as Figure 7 to Figure 10 As shown, the new flexible clamp also includes a fixing seat, on which a connecting nozzle 6 communicating with the positive and negative pressure system is arranged, and the connecting port 23 of the chuck is set and fixed on the connecting nozzle 6 . The positive and negative pressure system is a commonly used system at present, and an air pump is used to realize air extraction or inflation.

[0044] The fixed seat is an elastically telescopic fixed seat, and the fixed seat includes a flange seat 3 and an elastic telescopic sliding rod 4 installed on the flange seat 3, and the connecting nozzle 6 is installed on the end of the telescopic rod 4 . Certainly, the flexible clamp may not have the elastic buffer function.

[0045] Such as Figure 7 to Figure 9 As shown, the fixed seat includes a flange seat 3, a guide sleeve 5 is fixed on ...

Embodiment 3

[0049] This embodiment discloses a novel flexible clamping pen 10 using the flexible chuck in Embodiment 1. The flexible clamping pen 10 includes a pen cover 101 and a refill 102, and a piston 104 is axially slidably installed in the pen cover 101 , the piston 104 divides the inner cavity of the pen cap 101 into a front chamber 106 and a rear chamber 107, the front end of the pen core 102 is connected with the piston 104, the tail of the pen cap 101 is fixed with a tail plug 103, and the pen core 102 runs through the tail plug 103, the front end of the pen cover 101 is provided with a connecting nozzle 6 communicating with the front chamber 106, the communication port 23 of the flexible chuck is set and fixed on the connecting nozzle 6 of the pen cover 101, the piston A spring 105 is arranged between 104 and the pen cover 101 , and the spring 105 exerts a backward elastic force on the piston 104 . In this embodiment, the refill 102 and the piston 104 are integrally formed, and...

Abstract

The invention discloses a novel flexible chuck which comprises a clamping part made of elastic materials and a connecting part. The clamping part comprises at least two matched fingertips for clamping, a finger seam is formed between every two fingertips, and a finger cavity is formed inside each fingertip; the connecting part comprises a communication cavity which is communicated with all finger cavities, and the connecting part is provided with a communication opening communicated with the communication cavity; and each fingertip comprises an inner wall close to the finger seam and an outer wall close to the finger seam, the thickness of the inner wall is smaller than the thickness of the outer wall, or the elasticity modulus of the inner wall is smaller than the elasticity modulus of the outer wall. The flexible chuck is suitable for clamping tiny objects. In addition, the invention discloses a flexible clamp and a flexible clamping pen which use the flexible clamp.

Description

technical field [0001] The invention relates to a flexible clip made of elastic material, and also relates to a flexible clamp and a flexible holding pen using the flexible clip. Background technique [0002] In the field of industrial automation, the grasping action at the end of the robotic arm is mainly completed by rigid mechanical grippers or vacuum suction cups. However, due to the difficulty in controlling the strength of rigid mechanical grippers, it is difficult to achieve non-destructive grasping of soft and fragile objects. It is difficult for vacuum suction cups to adapt to irregular objects with rough surfaces and holes during handling. This leads to limitations in both application scenarios. [0003] Flexible robotic fingers are made of elastic materials, which can grasp soft and fragile objects without causing damage to the objects themselves. The current flexible finger includes a fingertip and a knuckle, and the tail of the knuckle is configured as a coni...
