[0002] In order to improve the turnover efficiency and protect the connector, preventing physical damage and collision of the connector during turnover, the connector is usually loaded on a turnover tray for turnover.

[0003] However, in the process of implementing the embodiments of the present utility model, the inventor found that: currently, in order to pick and place the connector on and off the turnover tray, generally a vacuum suction pen is used for adsorption and picking and placing. However, the vacuum suction pen has requirements for the adsorption area and surface roughness of the connector. If the adsorption area is too small or the surface roughness is too large, the vacuum suction pen cannot adsorb the connector, resulting in the inability of the vacuum suction pen to pick and place connectors with different adsorption areas or surface roughnesses. Summary of the Utility Model

The third surface is opposite to the second surface. The shapes of the first anti-fooling structure 16 and the second anti-fooling structure 17 are different, so that the bottom plate 1 is asymmetrically arranged, and thus an anti-fooling effect is achieved between the bottom plate 1 and the turnover tray. Specifically, the first anti-fooling structure 16 is a first inclined plane, and the second anti-fooling structure is a second inclined plane. The angle between the first inclined plane and the second surface and the angle between the second inclined plane and the third surface are different. Of course, in some embodiments, the first anti-fooling structure 16 is a first arc surface, and the second anti-fooling structure 17 is a second arc surface. The radii of the first arc surface and the second arc surface are different. It should be noted that in addition to those described in the above examples, the first anti-fooling structure 16 and the second anti-fooling structure 17 can also be other structures, which will not be listed one by one here.

[0035] For the above-mentioned handle 2, please refer to Figure 5 , the handle 2 includes a handle body 21 and a cover plate 22. The handle body 21 is connected to the bottom plate 1, and the handle body 21 is for a user to hold. The cover plate 22 is connected to the handle body 21.

The rotating hole 212 penetrates through the handle body 21, the rotating hole 212 communicates with the rotating groove 211, and a part of the clamping component 3 is inserted through the rotating hole 212. The handheld part 213 is arranged on the surface of the handle body 21, and the shape of the handheld part 213 is arc-shaped, which is beneficial for the user's hand to hold.

[0037] The cover plate 22 covers the rotating groove 211. The cover plate 22 is provided with a through hole 221, and the through hole 221 communicates with the rotating groove 211. A part of the clamping component 3 passes through the through hole 221.

[0038] For the above-mentioned clamping component 3, please refer to Figure 6 , the clamping component 3 includes a placing part 31, a clamping part 32, a pushing part 33, a rotating shaft 34 and a key 35. The placing part 31 is fixed in the fixing groove 11. The clamping part 32 is arranged on the placing part 31. The pushing part 33 is arranged in the rotating groove 211, and one end of the pushing part 33 is connected to the clamping part 32. The rotating shaft 34 is rotatably inserted into the rotating hole 212, and the rotating shaft 34 is connected to the other end of the pushing part 33, so that the pushing part 33 can rotate relative to the rotating groove 211. The key 35 passes through the through hole 221 and is then connected to the pushing part 33. The key 35 is used for the user to conveniently rotate the pushing part 33 relative to the rotating groove 211.

[0039] The placing member 31 is provided with a sliding groove 311 and an insertion hole 312. The insertion hole 312 is arranged at the bottom of the sliding groove 311, and the insertion hole 312 communicates with the sliding groove 311 for the first positioning post 201 of the connector 200 to be inserted into the sliding groove 311 from the insertion hole 312.

[0040] The clamping member 32 is arranged in the sliding groove 311, and the clamping member 32 can slide along the sliding groove 311.

[0041] In some embodiments, the surface of the other end of the clamping member 32 is of an arc structure, so that when the clamping member 32 clamps the first positioning post 201 of the connector 200, it is a surface contact, which can provide more friction.

[0042] One end of the pushing member 33 is located in the sliding groove 311. A slot 331 is arranged at one end of the pushing member 33 for one end of the clamping member 32 to be inserted and fixed, so that the pushing member 33 can push the clamping member 32 to slide along the sliding groove 311 towards or away from the first positioning post 201 to clamp or release the first positioning post 201.

[0043] It can be understood that, in some embodiments, the structure of the clamping member 32 is not limited to the above structure. The structure of the clamping member 32 can be other structures. One end of the clamping member 32 is provided with a first pushing portion 321 and a second pushing portion 322. One end of the pushing member 33 is located between the first pushing portion 321 and the second pushing portion 322. There is a gap between the side wall of the slot 331 and one end of the clamping member 32, so as to facilitate the disassembly and assembly of the pushing member 33 and the clamping member 32. By pushing one end of the pushing member 33 against the first pushing portion 321, the clamping member 32 is pushed to slide towards the first positioning post 201 to clamp the first positioning post 201, or by pushing one end of the pushing member 33 against the second pushing portion 322, the clamping member 32 is pushed to slide away from the first positioning post 201 to release the first positioning post 201.

[0044] In some embodiments, the picking and placing jig 100 includes an elastic member. One end of the elastic member abuts against the wall surface of the rotating groove 211, and the other end of the elastic member abuts against the pushing member 33. Further, please refer to Figure 5 and Figure 6 , a first receiving groove 214 is arranged on the wall surface of the rotating groove 211, a second receiving groove 332 is arranged on the pushing member 33. One end of the elastic member is received in the first receiving groove 214 and abuts against the bottom of the first receiving groove 214. The other end of the elastic member is received in the second receiving groove 332 and abuts against the bottom of the second receiving groove 332. The elastic member is used to provide a restoring force to the pushing member 33.
