Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings:

in order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention.

Referring to fig. 1, 2, 4-7, one embodiment provides a picking module including a picking member 100 and a flexible member 200. Wherein:

as shown in fig. 4 and 5, the picking member 100 is capable of reciprocating.

In the view shown in fig. 4 and 5, the picking member 100 can be lifted up and down, and lowered to allow a portion of the picking member 100 to extend into the mating hole of the material, and raised to allow the picking member 100 to exit the mating hole.

Optionally, the picking member 100 is configured with a driving member, such as a motor or a cylinder capable of outputting a telescopic motion, so as to drive the picking member 100 to lift.

As shown in fig. 2 and 7, the flexible member 200 is disposed on the picking member 100, the flexible member 200 can expand or/and contract at least in a radial direction of the picking member 100, and the picking member 100 can move to allow at least a portion of the flexible member 200 to enter or exit the material engaging hole.

As shown in fig. 2, the flexible piece 200 is established in the outside of picking up piece 100, and the flexible piece 200 is made by flexible material to make the surface of flexible piece 200 can not scratch or injure the material when conflicting with the mating holes of material, simultaneously, flexible material conflicts with the material, can increase frictional force because of conflicting again, thereby the better material that picks up.

As shown in fig. 6, as the flexible member 200 expands toward the outside of the picking member 100, the flexible member 200 collides with the material to pick up the material. As shown in fig. 4 in conjunction with fig. 6, the flexible member 200 does not interfere with the material as the flexible member 200 is retracted toward the inner side of the picking member 100 to release the material.

As shown in fig. 6 and 7, the flexible member 200 can expand or contract at least along the radial direction of the picking member 100, when the flexible member 200 expands along the radial direction of the picking member 100 toward the outer side of the picking member 100, which is equivalent to that the picking member 100 extending into the material upper matching hole enlarges in the radial direction, the enlarged part, that is, the flexible member 200 collides with the hole wall of the material upper matching hole, and the friction force generated by the collision realizes the expansion effect, so that when the picking member 100 goes up and down, the material can be driven to synchronously go up and down and move, and the material can be picked up and moved. And when the flexible member 200 along pick up 100 radially towards the inboard shrink of pick up 100, also when the flexible member 200 resets or resumes original state, because the pore wall of mating holes on flexible member 200 no longer with the material contradicts to no longer produce frictional force, the tight effect of expanding also disappears, and then can not drive the synchronous lift removal of material when pick up 100 goes up and down again, pick up 100 can withdraw from the mating holes of material, and then loosen the material.

It should be noted that:

the radial direction of the picking member 100 is the direction of the picking member 100 in the horizontal direction in the perspective of fig. 2 and 6, for example, the radial direction is both left, right, front and back in the horizontal direction, and will not be described again.

According to the material taking module, materials are provided with matching holes, the matching holes are used for being matched with the material taking module to pick up and put down, when the materials need to be picked up, the picking piece 100 moves and at least one part of the flexible piece 200 enters the matching holes, then the flexible piece 200 expands outwards along the radial direction of the picking piece 100, so that the expansion part of the flexible piece 200 is abutted to the hole wall of the matching holes in the materials, the materials are expanded through expansion force generated by expansion and abutting, and then the picking piece 100 moves again to take away the materials; when materials need to be put down, the picking part 100 moves to an area where the materials need to be put down, then the flexible part 200 contracts inwards along the radial direction of the picking part 100, so that the flexible part 200 does not expand any more, further the flexible part 200 does not collide with the materials any more, further the expansion force disappears, the flexible part 200 is separated from the materials, the picking part 100 moves and drives the flexible part 200 to withdraw from a matching hole, and further the action of putting down the materials is completed; compare traditional structure, not only do not have the requirement to the surperficial level of material, can not lead to pressing from both sides bad material because of the clamping-force is too big moreover.

It can be understood that:

since the flexible member 200 is made of flexible material, when expanding, the expansion direction is multi-directional, and the expansion or contraction of the flexible member 200 along the radial direction of the picking member 100 means that the flexible member expands or contracts directly along the radial direction of the picking member 100, or although the flexible member does not expand or contract along the radial direction of the picking member 100, the expansion or contraction direction has a component in the radial direction of the picking member 100 to collide with the material, and the details are not repeated.

In one embodiment, referring to fig. 2, 3 and 7, the picking member 100 is provided with an air hole 121, the flexible member 200 is fixed on the picking member 100 and covers the air hole 121, and the air hole 121 is capable of introducing air for expanding the flexible member 200 along the radial direction of the picking member 100.

As shown in fig. 3, the picking member 100 is provided with air holes 121, and the air holes 121 allow air to flow therethrough. As shown in fig. 2, the flexible member 200 is fixed to the picking member 100, and the flexible member 200 covers the air hole 121 to cover the air hole 121. As shown in fig. 6 and 7, when the air holes 121 are filled with air, the air impacts the flexible member 200 back, so that the flexible member 200 is deformed and expanded by the impact of the air, and thus expands toward the outer side of the picking member 100 in the radial direction of the picking member 100, thereby expanding the material.

As shown in fig. 2, after the air holes 121 are not filled with air or the high-pressure air in the air holes 121 is released, the flexible member 200 does not expand due to no air impact on the flexible member 200, so as to retract to the original state, and at this time, the flexible member 200 does not expand tightly, so that the picking member 100 is driven to synchronously leave the flexible member 200 when exiting from the matching hole of the material, thereby lowering or loosening the material.

In one embodiment, referring to fig. 1, 2, 6 and 7, the flexible member 200 is disposed in a ring shape, and the flexible member 200 is sleeved on the picking member 100.

As shown in fig. 2 and 7, the flexible member 200 surrounds the sleeve and is sleeved on the picking member 100, and when the flexible member 200 expands, the flexible member 200 expands at multiple points on the periphery of the picking member 100 to perform multiple-point collision with the hole wall of the matching hole on the material, thereby realizing better collision effect.

Optionally, the flexible member 200 is a rubber ring, and when the air hole 121 inflates towards the inner surface of the rubber ring, the air hole 121 pushes the rubber ring to expand towards the radial outer side of the picking member 100, so that the outer surface of the rubber ring is in interference fit with the hole wall of the matching hole in the material, and at this time, the picking member 100 moves up and down and can drive the material to synchronously lift up and down, so as to transfer the material; when the air hole 121 stops inflating and the rubber ring is not subjected to pressure generated by air, the rubber ring is restored to the original state and does not abut against the hole wall of the matching hole in the material, the picking piece 100 withdraws from the matching hole and drives the rubber ring to leave the matching hole, and then the material is put down or loosened.

Optionally, the flexible member 200 is an air bag sleeved around the picking member 100, the air bag covers the air hole 121 and is communicated with the air hole 121, when the air hole 121 is inflated towards the inside of the air bag, the air bag expands and enables the outer surface of the air bag to be in interference fit with the hole wall of the matching hole in the material, and at the moment, the picking member 100 moves up and down and can drive the material to synchronously lift up and down so as to transfer the material; when the air hole 121 is not inflated towards the inside of the air bag or the air in the air bag is pumped away, the air bag shrinks so as not to be in contact with the hole wall of the matching hole in the material, the picking part 100 exits from the matching hole and drives the air bag to leave the matching hole, and then the material is put down or loosened.

In one embodiment, referring to fig. 3 and 6, the air holes 121 are provided in a plurality, and the plurality of air holes 121 are spaced along the circumferential direction of the picking member 100.

So set up, the flexible piece 200 covers all gas pockets 121, when being full of gas in the gas pocket 121, the atmospheric pressure that gas produced promotes the radial expansion of flexible piece 200 towards picking up piece 100, at this moment, because each position of arranging of gas pocket 121 corresponding flexible piece 200, therefore can make the radial outside inflation towards picking up piece 100 of each part homoenergetic relative equilibrium of flexible piece 200, thereby make each part of flexible piece 200 and the pore wall different parts homoenergetic of mating holes contradict each other, thereby realize better pick-up effect.

In another embodiment, the air holes 121 are annular holes, and the air holes 121 extend along the circumferential direction of the picking member 100.

In this embodiment, the air holes 121 extend around the outer periphery of the picking member 100, and when the air holes 121 are filled with air, the air impacts the flexible member 200 around the air holes 121, thereby expanding the flexible member 200 radially outward of the picking member 100 to also achieve an interference fit with the wall of the mating hole.

Alternatively, the annular holes may be spaced in the axial direction of the picking member 100 to allow the air to impinge on the flexible member 200 at different locations, thereby allowing the portions of the flexible member 200 to expand relatively uniformly.
