Specifically, the grasping portions include a first grasping portion 2 and a second grasping portion 5. The first gripper section 2 and the first gripper section 5 have the same structure. The first gripping part 2 and the second gripping part 5 are arranged in axial symmetry with respect to the axis of the support arm 1.

In the present embodiment, a connection plate 11 is connected to the end of the support arm 1. The first grabbing part 2 and the second grabbing part 5 are respectively connected to two opposite side surfaces of the connecting plate 11 and are arranged in a back-to-back mode.

More specifically, the first portion of snatching 2 and the one side that connecting plate 11 was kept away from to the second portion of snatching 5 all sets up owing to two snatch the station to the realization can once only snatch two cell-phones.

When the multi-station feeding and discharging clamp is used, two mobile phones can be tested simultaneously in the test fixture. When the mechanical arm works, the first grabbing part 2 grabs two mobile phones to be tested at one time, the mechanical arm drives the clamp to enter the test fixture, at the moment, the first grabbing part 2 faces upwards, two grabbing stations on the second grabbing part 5 are vacant, the second grabbing part 5 is used for grabbing the two mobile phones which are tested in the test fixture, and the two mobile phones to be tested on the first grabbing part 2 are placed in the test fixture after the supporting arm 1 rotates 180 degrees. The mobile phone is taken out of and put into the test fixture through one-time action of the mechanical arm, the use flexibility is strong, and the work efficiency is high.

Further, the first grasping portion 2 includes a first jaw 26, a second jaw 25, and a driving portion. Specifically, the first gripper section 2 further includes a first jaw connection plate 22 and a second jaw connection plate 23. The first jaw 26 is attached to the first jaw attachment plate 22 and the second jaw 25 is attached to the second jaw attachment plate 23. The driving part is used for driving the first clamping jaw connecting plate 22 and the second clamping jaw connecting plate 23 to move oppositely or reversely; when the two move towards each other, the first clamping jaw 26 and the second clamping jaw 25 are driven to approach each other, so that the mobile phone can be grabbed; when the first clamping jaw 26 and the second clamping jaw 25 move back to back, the first clamping jaw 26 and the second clamping jaw 25 are driven to be away from each other, and the mobile phone is released.

In this embodiment, the first clamping jaw 26 on the first clamping jaw connecting plate 22 and the second clamping jaw 25 on the second clamping jaw connecting plate 23 are both provided in two, two first clamping jaws 26 are arranged at intervals, two second clamping jaws 25 are arranged at intervals, and a grabbing station is formed between the four clamping jaws.

In this embodiment, the first jaw connecting plate 22 and the second jaw connecting plate 23 are both provided with an elongated slot for connecting the first jaw 26 and the second jaw 25, so as to adjust the positions of the first jaw 26 and the second jaw 25, and further adapt to mobile phones of various models.

In this embodiment, the first clamping jaw connecting plate 22 and the second clamping jaw connecting plate 23 are both provided with two clamping stations, so that the first clamping part 2 is provided with two clamping stations.

In the present embodiment, the driving portion employs an air cylinder 21 for driving the first jaw connecting plate 22 and the second jaw connecting plate 23 on one gripping station to move synchronously.

In the present embodiment, the first gripper section 2 further includes a support plate 29 and a backing plate 28. Specifically, the cylinder 21 is connected to a side of the support plate 29 close to the connection plate 11, and the first and second

jaw connection plates

22 and 23 are slidably connected to a side of the support plate 29 away from the connection plate 11. The two ends of the supporting plate 29 far away from the connecting plate 11 are provided with backing plates 28, and the mobile phone is abutted against the backing plates 28 when the mobile phone is grabbed.

Further, a layer of elastomer 251 is provided on the inside of the second jaw 25. The inner side of the first clamping jaw 26 is also provided with an elastic glue layer, so that the friction force is increased, the grabbing firmness is improved, and the mobile phone is prevented from falling off carelessly.

In this embodiment, the elastic glue layer is made of silicone.

Further, a position sensor is further arranged between the first clamping jaw 26 and the second clamping jaw 25 on the grabbing station, and is used for sensing whether a mobile phone is arranged on the grabbing station or not.

In the present embodiment, the position sensor employs the photoelectric sensor 27.

Further, a sucker assembly 24 is arranged in the grabbing station. In this embodiment, there are 4 sucker assemblies 24, distributed in the grabbing station. When the mobile phone is grabbed, the sucker assembly 24 firstly contacts and adsorbs the mobile phone, and then the air cylinder 21 is started to drive the clamping jaws to further grab the mobile phone. The arrangement of the sucker assembly 24 further improves the firmness of grabbing the mobile phone.

Further, the sucking disc that sucking disc subassembly 24 is used for adsorbing the work end of cell-phone adopts the traceless silica gel material, guarantees absorbent validity.

Furthermore, a pressure sensor (not shown in the figure) is arranged at the non-working end, far away from the sucker, of the sucker component, so that the pressure of the contact surface of the mobile phone is fed back in real time, and pressure injury is prevented.

Further, a sliding connection is achieved between the first grip part 2 and the connection plate 11 of the support arm 1 by means of the guide shaft 3. Correspondingly, the second grabbing part 5 is connected to the other end of the guide shaft 3 in a sliding manner. Therefore, when the mobile phone is grabbed, the first grabbing part 2 and the second grabbing part 5 both have certain allowance of moving space, and the mobile phone is prevented from being crushed.

In the present embodiment, the guide shaft 3 vertically penetrates the connecting plate 11, a linear bearing is arranged at one end of the guide shaft 3, and the support plate 29 of the first grabbing part 2 is connected through the linear bearing, so as to realize the sliding connection of the first grabbing part 2 on the guide shaft 3. At the other end of the guide shaft 3, a linear bearing is also adopted to be connected with the second grabbing part 5, so that the sliding connection between the second grabbing part 5 and the guide shaft 3 is realized.

Further, be in the both sides of connecting plate 11 on guiding axle 3, all the cover is equipped with compression spring 4, and compression spring 4 supports first portion 2 and the second portion 5 of snatching respectively, can the elastic support first portion 2 and the second portion 5 of snatching automatic re-setting, and the flexibility is good.
