Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0033] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as there is no conflict between them.

[0035] The utility model provides a kind of suction cup pick-and-place device as shown in Figure 1 、 Figure 2 And Figure 3 Suction cup pick-and-place device is a device that uses negative pressure suction force to grasp objects, which is used to help production line workers grasp and fix workpieces, especially some very thin and small non-metallic structural parts that are difficult to pick up directly with hands. The main structure of the suction cup pick-and-place device of the present application includes: device housing 1, negative pressure suction head 2 and negative pressure assembly 3. In some embodiments, the outer side wall of the device housing 1 is provided with a hand grip 11, which is used for user hand holding. The negative pressure suction head 2 is arranged at one end of the device housing 1, and the negative pressure suction head 2 is used to suck the workpiece. The negative pressure assembly 3 is arranged in the device housing 1, and the negative pressure assembly 3 is used to provide negative pressure suction force for the negative pressure suction head 2 to help the negative pressure suction head 2 suck the workpiece. The device housing 1 is movably connected with a handle 12, and the handle 12 is used to generate negative pressure suction force or restore normal pressure of the negative pressure assembly 3. When the handle 12 is closed, the handle 12 drives the negative pressure assembly 3 to generate negative pressure suction force. When the handle 12 is unfolded, the negative pressure assembly 3 restores normal pressure, so that the negative pressure suction head 2 loses suction force on the workpiece. When the negative pressure suction head 2 sucks the workpiece, it is necessary to ensure the air tightness between the surface of the workpiece sucked and the negative pressure suction head 2 to ensure the success of workpiece suction.

[0036] It should be noted that there are some magnetic devices that can assist workers in picking up light and thin metal workpieces. However, such magnetic devices can only work on metal workpieces and cannot grasp non-metal workpieces.

[0037] The device can be used to suck and transfer the workpiece by the negative pressure component 3. When the worker needs to suck the workpiece, he only needs to hold the hand-held part 11 of the device to make the handle 12 close, and the handle 12 drives the negative pressure component 3 to generate negative pressure on the negative pressure suction head 2 to suck up the workpiece. When the worker needs to put down the workpiece, he only needs to release the handle 12 to make the negative pressure component 3 return to normal pressure, so that the negative pressure suction head 2 releases the workpiece. In this way, the worker can efficiently take and put the small and thin workpiece, especially the non-metal workpiece. In addition, the worker can avoid directly contacting the workpiece, and the fingerprints on the fingers of the worker can also avoid polluting the surface of the workpiece.

[0038] Further, as shown in Figure 3 and Figure 4 , the negative pressure component 3 comprises a cylinder body 31, a piston 32, a connecting rod 33 and an extension pipe 34. The cylinder body 31 is arranged in the device housing 1. The piston 32 is movably connected in the cylinder body 31. The two ends of the connecting rod 33 are movably connected to the piston 32 and the handle 12 respectively, and the connecting rod 33 is used to drive the piston 32 to move along the extension direction of the cylinder body 31. The cylinder body 31 and the negative pressure suction head 2 are connected through the extension pipe 34.

[0039] It can be understood that when the handle 12 is closed, the handle 12 drives the piston 32 to move in the cylinder body 31 through the connecting rod 33, so that the negative pressure cavity 312 connected with the pipeline of the cylinder body 31 expands, the air pressure in the negative pressure cavity 312 is less than the air pressure outside, and then the negative pressure suction head 2 generates negative pressure to suck the workpiece.

[0040] Further, as shown in Figure 3 and Figure 4 , the cylinder body 31 is provided with a pressure cavity 311, and the piston 32 is movably connected in the pressure cavity 311. The piston 32 divides the pressure cavity 311 into a negative pressure cavity 312 and a reset cavity 313. The negative pressure suction head 2 is connected with the negative pressure cavity 312 through the extension pipe 34. The negative pressure cavity 312 is used to provide negative pressure to the negative pressure suction head 2. The reset cavity 313 is used to make the handle 12 return to the unfolded state.

[0041] It can be understood that the negative pressure cavity 312 is connected with the negative pressure suction head 2 through the pipeline, and the reset cavity 313 is a sealed cavity. When the piston 32 is driven, the size of the space of the reset cavity 313 changes, and the air pressure in the reset cavity 313 also changes. Therefore, the air pressure difference between the reset cavity 313 and the outside will drive the piston 32 to reset. Then, the handle 12 is driven to return to the unfolded state through the connecting rod 33. In this way, the practicality and convenience of the device are improved.

[0042] In some embodiments, the negative pressure cavity 312 and the reset cavity 313 are arranged oppositely.

[0043] Further, as shown in Figure 3 and Figure 4As shown, the two ends of the piston 32 in the extending direction of the cylinder 31 are provided with piston heads 321, and the two piston heads 321 are movably connected in the negative pressure cavity 312 and the reset cavity 313 respectively. At least one sealing ring 322 is arranged on the outer side wall of each of the two piston heads 321. It can be understood that the sealing performance of the piston head 321 and the inner wall of the cylinder can be effectively improved by the sealing ring 322. The air tightness of the negative pressure cavity 312 and the reset cavity 313 is ensured, and air leakage of the negative pressure cavity 312 and the reset cavity 313 is avoided, so as to affect the normal use of the device.

[0044] Further, as shown in Figure 3 The limiting portion 13 is arranged on the device shell 1, and the limiting portion 13 abuts against the handle 12 when the handle 12 is in the unfolded state. The limiting portion 13 is used to limit the unfolding angle of the handle 12. It can be understood that in the embodiment, the unfolding angle of the handle 12 is limited by the limiting portion 13. The unfolding angle of the handle 12 is prevented from being too large, and the stroke of the piston 32 exceeds the preset range, so that the piston 32 is separated from the cylinder.

[0045] Further, the negative pressure suction head 2 is detachably connected to one end of the device shell 1. It can be understood that in the embodiment, the negative pressure suction head 2 may be damaged after long-term high-intensity use, which affects its air tightness. Therefore, the negative pressure suction head 2 is configured to be detachably connected to one end of the device shell 1, so that the staff can conveniently replace the negative pressure suction head 2 regularly, and ensure that the negative pressure suction force of the negative pressure suction head 2 is sufficient.

[0046] Further, as shown in Figure 3 and Figure 5 The sealing rubber ring 21 is arranged on the negative pressure suction head 2, and the sealing rubber ring 21 is connected to the extension pipe 34 in a pipeline manner. The sealing rubber ring 21 is used to suck the workpiece. The air tightness between the extension pipe 34 and the contact surface of the workpiece is ensured by the sealing rubber ring 21. The staff can replace the negative pressure suction head 2 of different sizes according to workpieces of different sizes, so as to better suck and transfer the workpiece.

[0047] Further, as shown in Figure 3 and Figure 5 The sealing rubber ring 21 is arranged on the negative pressure suction head 2, and the sealing rubber ring 21 is connected to the extension pipe 34 in a pipeline manner. The sealing rubber ring 21 is used to suck the workpiece. The air tightness between the extension pipe 34 and the contact surface of the workpiece is ensured by the sealing rubber ring 21. The staff can replace the negative pressure suction head 2 of different sizes according to workpieces of different sizes, so as to better suck and transfer the workpiece.

[0048] Further, the extension pipe 34 is a metal pipe.

[0049] The metal pipe has strong structural strength and can not be deformed to a certain extent due to the change of internal air pressure. Further, the negative pressure suction force on the negative pressure suction head 2 is sufficient to suck the workpiece.

[0050] In summary, the application provides a suction cup taking and placing device. When a worker needs to suck a workpiece, he or she only needs to hold the hand holding part 11 of the device to make the handle 12 close, and the handle 12 drives the negative pressure assembly 3 to generate a negative pressure suction force on the negative pressure suction head 2 to suck up the workpiece. When the workpiece needs to be placed down, the handle 12 is released to make the negative pressure assembly 3 return to normal pressure, so that the negative pressure suction head 2 releases the workpiece. In this way, the worker can efficiently take and place small and thin workpieces, especially non-metal workpieces.
