The working principle of the grabbing and pressing device for the O-shaped terminal and the cable in the embodiment is as follows:

when the O-shaped terminal and the cable need to be pressed together, the controller firstly controls the fifth motor 64 in the second driving unit 60 of the clamping jaw transverse adjusting structure 55 to drive the first bevel gear 62 to rotate forwardly, and then the second bevel gear 63 rotates to drive the synchronous pulley 58 to rotate forwardly, and then the first synchronous belt 59 drives the sliding plate 57 to slide along the sliding groove 61, the supporting plate 50 fixed on the sliding plate 57 moves, and then the clamping jaw angle adjusting structure 46 arranged on the supporting plate 50 moves integrally therewith, so that the transverse movement of the clamping jaw structure 9 is realized.

When the support plate 50 touches the limit switch arranged on the second positioning shell 56, the limit switch sends a position signal of the clamping jaw structure 9 at the moment to the controller, the controller controls the fifth motor 64 to stop running, and then controls the third driving unit 68 in the clamping jaw front-and-back adjusting structure, the sixth motor drives the first cam 70 to rotate, so as to drive the positioning rod 71, the first-stage movable rod 72 and the second-stage movable rod 73 to move, so that the movable box 66 moves back and forth along the guide rail 67, and further drives the second positioning shell 56 to move to a limit position along the guide rail 67 in a direction close to the sleeving and taking column, so that the clamping jaw transverse adjusting structure 55 and the clamping jaw angle adjusting and controlling structure 46 move back and forth, so that the clamping jaw structure 9 can be adjusted to be right in front of an O-shaped end more flexibly, and the clamping jaw structure can be convenient.

When the controller controls the sixth motor to drive the first cam 70 to rotate, the convex side of the first cam 70 presses down the prying rod 74, and the other end of the prying rod 74 presses up the end pressing platform 3 to a position flush with the clamping jaw transverse adjusting structure 55 through the connecting column 75; the convex surface vertex of the first cam 70 is provided with a limit switch, when the pressing end platform 3 is flush with the clamping jaw transverse adjusting structure 55, the limit switch on the first cam 70 is just in a triggered state (at this time, the second positioning shell 56 also just moves to the limit position of the guide rail 67), the limit switch can send a signal to the controller, and the controller controls the sixth motor to stop running.

Then, in the clamping jaw structure 9, the seventh motor 80 drives the bidirectional screw rod 79 to rotate, and the rotation of the bidirectional screw rod 79 enables the first petal clamping claw 77 to move along the direction close to the second petal clamping claw 78, so that the clamping of the O-shaped terminal is realized; when the O-shaped terminal is clamped, the gravity sensor (model HX 711) on the second petal clamping claw 78 transmits a signal to the controller, the controller controls the clamping jaw angle adjusting structure 46, the fourth motor 49 drives the first driving gear 51 to rotate, so as to drive the first driven gear 52 and the second driven gear 53 to rotate, so that the first rotating rod 47 and the second rotating rod 48 drive the positioning plate 54 to rotate, and further drive the clamping jaw structure 9 fixed on the positioning plate 54 to rotate, thereby realizing the angle adjustment of the clamping jaw structure 9, so that the clamping jaw mechanism 9 rotates the clamped O-shaped terminal to the cushion blocks 90 on the O-shaped terminal placing grooves 82 on both sides of the pressure end platform 3, after the gravity sensor (model HX 711) on the cushion block 90 detects that the O-shaped terminal is placed on the cushion block 90, the gravity sensor transmits a signal to the controller, the controller controls the clamping jaw structure 9, and the seventh motor 80 drives the bidirectional screw rod 79 to rotate reversely, the reverse rotation of the bidirectional screw 79 causes the first petal gripping claw 77 to move in a direction in which it is away from the second petal gripping claw 78 to release the O-type terminal.

The controller controls the sixth motor again to drive the first cam 70 to rotate continuously, and the prying rod 74 restores the pressure end platform 3 to the initial state through the connecting column 75, namely, the pressure end platform is positioned below the grabbing mechanism 2 (due to the structure, the occupied area of the device is small, and the space of a plant is saved); at this time, the limit switch on the first cam 70 is in an unfired state again, the controller controls the eighth motor 89 in the fourth driving unit 86 to drive the second cam 88 to rotate, when the second cam 88 rotates to the protruding position, the two-piece tapered hole piece of the split tapered hole 83 separates to the limit position along the guide rail 84, the spring 85 is stretched, the split tapered hole 83 is opened, then the two ends of the cable are respectively placed in the split tapered holes 83 with the two ends opened, and the two ends of the cable are inserted into the ports of the O-shaped terminals manually.

When the two-petal tapered hole petals are separated to the limit position along the guide rail 84, the two-petal tapered hole petals touch the limit switch on the guide rail 84, the limit switch sends a signal to the controller, the controller controls the eighth motor 89 in the fourth driving unit 86 to drive the second cam 88 to rotate continuously, the two-petal tapered hole petals of the separated tapered hole 83 are driven to be closed, the spring 85 returns to the original state, and at the moment, the two ends of the cable are clamped by the separated tapered hole 83.

Then, in the fifth driving unit 92 in the needle pressing mechanism 4, the controller controls the ninth motor to drive the needle pressing translation rotating shaft 96 to rotate, so as to drive the third synchronous belt 98 to move, thereby realizing that the needle pressing housing 95 fixed below the third synchronous belt 98 moves, so as to realize that the needle pressing 94 located in the needle pressing housing 95 moves to a position right above the O-shaped terminal placing groove 82 located on one side.

Then the controller controls the ninth motor to stop running, and then drives the tenth motor 99 in the sixth driving unit 93 to drive the driving rotating rod 100 to rotate, so as to drive the driven rotating rod 101 to move downwards, further drive the driven block 102 to move downwards, further drive the press pin 94 to move downwards, and achieve the purpose of pressing the O-shaped terminal below the press pin 94 and one end of the cable together; after the controller controls the pressing pin to be pressed down for a period of time, the tenth motor 99 in the sixth driving unit 93 is controlled to drive the driving rotary rod 100 to continue rotating, so as to drive the driven rotary rod 101 to move upwards, further drive the driven block 102 to move upwards, and further drive the pressing pin 94 to move upwards; next, the controller controls a ninth motor in the fifth driving unit 92 to drive the needle pressing translation rotating shaft 96 to rotate reversely, so as to drive the third synchronous belt 98 to move reversely, further drive the needle pressing housing 95 to move reversely until the needle pressing 94 is located right above the O-shaped terminal placing groove 82 on the other side, and then the controller controls the sixth driving unit 93 to drive the needle pressing 94 to press downwards in the same manner, so as to press the O-shaped terminal and the cable on the other side.
