The working principle of the pressing air injection recovery device for the O-shaped terminal and the cable in the embodiment is as follows:
when the O-type terminal and the cable are required to be pressed together, the controller will first control 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 forward, then the second bevel gear 63 rotates, and drives the synchronous pulley 58 to rotate forward, and then the first synchronous belt 59 drives the sliding plate 57 to slide along the sliding groove 61, the support plate 50 fixed on the sliding plate 57 moves, and then the clamping jaw angle adjusting structure 46 arranged on the support plate 50 moves integrally therewith, so as to realize the transverse movement of the clamping jaw structure 9.
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 to the controller, the controller controls the fifth motor 64 to stop running, then controls the third driving unit 68 in the clamping jaw front-rear adjusting mechanism, the sixth motor drives the first cam 70 to rotate, drives 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 forwards and backwards along the guide rail 67, and further drives the second positioning shell 56 to move to a limit position along the guide rail 67 towards a direction close to the sleeving column, and further, the clamping jaw transverse adjusting structure 55 and the clamping jaw angle adjusting structure 46 move forwards and backwards, so that the clamping jaw structure 9 can be flexibly adjusted to be right ahead of the O-shaped end, and clamping of the O-shaped end is facilitated.
While 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 bar 74, and the other end of the prying bar 74 presses the end pressing platform 3 to a position flush with the clamping jaw transverse adjusting structure 55 through the connecting column 75; a limit switch is installed at the convex top of the first cam 70, when the end pressing 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), and the limit switch sends 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 clack clamping claw 77 to move along the direction of approaching to the second clack clamping claw 78, so that the clamping of the O-shaped terminal is realized; when the O-shaped terminal is clamped, a gravity sensor (model HX 711) on the second 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, thereby driving the first driven gear 52 and the second driven gear 53 to rotate, 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, so that the angle adjustment of the clamping jaw structure 9 is realized, the clamping jaw mechanism 9 rotates the clamped O-shaped terminal to cushion blocks 90 on the O-shaped terminal placing grooves 82 on two sides of the pressing end platform 3, the gravity sensor (model HX 711) on the cushion blocks 90 detects that the O-shaped terminal is placed on the cushion blocks 90, the controller controls the clamping jaw structure 9 to rotate reversely, and the seventh motor 80 drives the bidirectional screw 79 to rotate reversely, so that the first clamping claw 77 moves away from the second clamping claw 78 along the direction of the clamping jaw structure, and the O-shaped terminal is released.
Then the controller controls the sixth motor again to drive the first cam 70 to rotate continuously, the prying rod 74 returns the end pressing platform 3 to the initial state through the connecting column 75, namely, the end pressing platform is positioned below the grabbing mechanism 2 (the structure ensures that the device occupies a small area and saves factory space); at this time, the limit switch on the first cam 70 is in the non-triggered state again, the controller controls the eighth motor 89 in the fourth driving unit 86 to drive the second cam 88 to rotate, the two-lobe cone Kong Ban of the split cone hole 83 is separated to the limit position along the guide rail 67 when the second cam 88 rotates to the convex position, the spring 85 is stretched, the split cone hole 83 is opened, then both ends of the cable are manually placed in the split cone holes 83 with both ends opened respectively, and both ends of the cable are inserted into the ports of the O-shaped terminal.
When the two-lobe cone Kong Ban is separated to the limit position along the guide rail 67, the limit switch on the guide rail 67 is touched, a signal is sent to the controller by the limit switch, the controller controls the eighth motor 89 in the fourth driving unit 86 to drive the second cam 88 to rotate continuously, the two-lobe cone Kong Ban of the separated cone hole 83 is 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 cone hole 83.
Then, the controller controls the fifth driving unit 92 in the needle pressing mechanism 4, and the ninth motor drives the needle pressing translation rotating shaft 96 to rotate, so as to drive the third synchronous belt 98 to move, so that the needle pressing shell 95 fixed below the third synchronous belt 98 moves, and the needle pressing 94 in the needle pressing shell 95 moves to be right above the O-shaped terminal placing groove 82 on one side.
Then the controller controls the ninth motor to stop running, then drives the tenth motor 99 in the sixth driving unit 93 to drive the driving rotating rod 100 to rotate, drives the driven rotating rod 101 to move downwards, further drives the driven block 102 to move downwards, further drives the pressing needle 94 to move downwards, and achieves the purpose of pressing the O-shaped terminal below the pressing needle 94 and one end of the cable together; after the controller controls the pressing needle to press downwards for a period of time, a tenth motor 99 in the sixth driving unit 93 is controlled to drive the driving rotating rod 100 to rotate continuously, so as to drive the driven rotating rod 101 to move upwards, further drive the driven block 102 to move upwards, and further drive the pressing needle 94 to move upwards; then the controller controls the ninth motor in the fifth driving unit 92 to drive the pin translation rotating shaft 96 to rotate reversely, and then drives the third synchronous belt 98 to move reversely, and then drives the pin housing 95 to move reversely until the pin 94 is positioned 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 pin 94 to press down in the same manner as described above, so that the pressing ends of the O-shaped terminals and the cables on the other side are realized.
After the two ends are pressed, the controller controls the nozzle of the air gun to spray high-pressure air, the high-pressure air is sprayed out from the air spraying holes 91 through the pipeline, the O-shaped terminals on the cushion block 90 are sprayed, and then the O-shaped terminals are communicated with a cable connected with the O-shaped terminals and fall below the frame 81 due to self gravity to enter the next process.
The foregoing embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
