Embodiment 1

[0021] The clamping device for manipulators to clamp plastic parts includes an air suction pipe 2, a corrugated suction cup 3 and an extrusion air bag 31. The corrugated suction cup 3 includes an air suction end and an adsorption end. Lip 4 concentric with the outer edge of the suction end (such as figure 2 shown), the lip 4 has multiple layers, and a leak-proof cavity 41 is formed between the lip 4 and the outer edge of the adsorption end. The extrusion airbag 31 is located on both sides of the corrugated suction cup 3. A connecting pipe is provided between the air bag 31 and the leak-proof cavity 41, and an exhaust port is provided on the connecting pipe, and a one-way valve 5 is provided at the exhaust port, and two arcs in the shape of an inverted "eight" are also included. Shaped chute 6, the chute 6 is arranged on the manipulator 1, the two sections of chute 6 are respectively located above the two extruded airbags 31, the two sections of chute 6 are provided with slide...

Embodiment 2

[0026] Compared with Embodiment 1, the difference is that a spring 32 is arranged inside the extruding airbag 31, and the two ends of the spring 32 are respectively fixed to the top and bottom of the extruding airbag 31, and the upper surface of the leg 72 is provided with a sponge material. As for the buffer pad, the lower surface of the supporting foot 72 is provided with rollers. After the extrusion airbag 31 is deformed, the recovery ability is increased, that is, the ability of the extrusion airbag 31 to form negative pressure is enhanced. The bumper prevents the feet 72 from scratching the surface of the plastic part.

Embodiment 3

[0027] Example 3 (as figure 1 shown)

[0028] Compared with Embodiment 2, the difference lies in that a compression spring 8 is provided at the ends of the slider and the slide groove 6 . The stage clip 8 withstands the slide block, so that the slide block can always be kept at the lower end of the chute 6, that is, the state that the supporting legs 72 are kept closed.

Abstract

The invention relates to the field of sucker devices, in particular to a clamping device for clamping a plastic part with a mechanical hand. The clamping device comprises a suction pipe, a corrugated sucking disc and extrusion air bags; the corrugated sucking disc comprises a suction end and an adsorption end, the suction end is communicated with the suction pipe, a lip side concentric with the outer edge of the adsorption end is arranged on the adsorption end, and an anti-leakage cavity is formed between the lip side and the outer edge of the adsorption end; the extrusion air bags are located at the two sides of the corrugated sucking disc and fixed to a mechanical arm, a communication pipe is arranged between each extrusion air bag and the anti-leakage cavity and provided with an exhaust port, and a one-way valve is arranged on each exhaust port; the clamping device further comprises two sliding grooves in an inverted splayed shape, the sliding grooves are formed in the mechanical hand and located above the two extrusion air bags respectively, and sliding blocks are arranged in the two sliding grooves. The clamping device for clamping the plastic part with the mechanical hand is provided to solve the problem that an existing plastic part is prone to falling in the carrying process.

Description

technical field [0001] The invention relates to the field of suction cup devices, in particular to a clamping device for a manipulator to clamp plastic parts. Background technique [0002] Laptop computers can be made of steel or plastic shells, because the cost of using steel shells is relatively high, and the steel shell needs to be additionally equipped with an insulating layer, which will lead to an increase in the cost of the steel shell. Most laptops now have plastic casings. [0003] Most of the casings of notebook computers are made of engineering plastics, and the casings of engineering plastics are formed by injection molding. After the casings are formed, the plastic parts need to be moved from the injection molding machine to the next station for processing. Plastic parts are usually moved by means of manipulators. The shape of the plastic parts is irregular, and it is easy to scratch and damage the shell when the manipulator directly grabs the mobile shell. I...
