[0023] The bending assembly 4 includes a bracket 41, a straight-push cylinder 42, a push piece 43, two loosening cylinders 44, a discharge plate 45 and a loading plate 46. The bracket 41 is positioned on the workbench 1, the cylinder body of the straight-push cylinder 42 is positioned at the top of the bracket 41 and the output shaft of the straight-push cylinder 42 faces the turntable 2, the push piece 43 is positioned on the output shaft of the straight-push cylinder 42 and the height of the push piece 43 is higher than the height of the bending station 211, the two loosening cylinders 44 are respectively positioned on the bracket 41 and the workbench 1, the output shaft of the loosening cylinder 44 on the bracket 41 is fixedly connected to the discharge plate 45, the output shaft of the loosening cylinder 44 on the workbench 1 is fixedly connected to the loading plate 46, the discharge plate 45 is arranged corresponding to the discharge station 212, and the loading plate 46 is arranged corresponding to the loading station 213;

[0024] The feeding assembly 5 includes a vibration plate 51, a material channel 52, a straight vibrator 53, a rotary motor 54 and a finger cylinder 55. The vibration plate 51 and the straight vibrator 53 are both positioned on the workbench 1, the material channel 52 is positioned above the straight vibrator 53, one end of the material channel 52 is connected to the vibration plate 51 and the other end is located at one side of the feeding station 213, the rotary motor 54 is fixed relative to the workbench 1 and is arranged near the end of the material channel 52 extending to the feeding station 213, the cylinder body of the finger cylinder 55 is fixedly connected to the output shaft of the rotary motor 54 and the finger cylinder 55 is located just above the end of the material channel 52;

[0025] In the initial state, the ends of the multiple clamping rods 23 facing the center of the turntable 2 are tilted relative to the surface of the turntable 2, and the ends of the multiple clamping rods 23 near the edge of the turntable 2 are in contact with the surface of the turntable 2. The finger cylinder 55 is arranged perpendicular to the upper surface of the material channel 52, and the two output shafts of the finger cylinder 55 are respectively located on both sides of the material channel 52; the processing process is as follows: in the first step, the vibration plate 51 and the straight vibrator 53 successively move the terminal into the material channel 52 and move the terminal to the end of the material channel 52 near the loading station 213, the sheet part of the terminal is located in the material channel 52 and the annular part is located above the material channel 52; in the second step, the finger cylinder 55 clamps the annular part of the terminal, and then rotates The motor 54 drives the finger cylinder 55 to rotate, and at the same time, the loosening cylinder 44 equipped with the feeding plate 46 starts and drives the feeding plate 46 to press the end of the clamping rod 23 at the feeding station 213 toward the center of the turntable 2, and the clamping rod 23 rotates relative to the fixed block 22. The end of the clamping rod 23 toward the center of the turntable 2 touches the turntable 2 and the other end thereof is tilted relative to the turntable 2, and the torsion spring undergoes corresponding elastic deformation. As the rotating motor 54 rotates into place, the sheet part of the terminal rotates to between the end of the clamping rod 23 and the turntable 2; in the third step, the loosening cylinder 44 equipped with the feeding plate 46 is reset, and the clamping rod 23 at the feeding station 213 recovers its elastic deformation as the torsion spring recovers, and the end of the clamping rod 23 toward the center of the turntable 2 The end of the clamping rod 23 near the edge of the rotating disk 2 is tilted relative to the rotating disk 2 and the end near the edge of the rotating disk 2 is close to the rotating disk 2 until the end of the clamping rod 23 near the edge of the rotating disk 2 and the rotating disk 2 clamp the sheet body of the terminal together, and the finger cylinder 55 and the rotating motor 54 are reset successively; the fourth step, the terminal loaded to the loading station 213 moves to the bending station 211 as the rotating disk 2 rotates, and the annular body part of the terminal is facing the push piece 43, and the straight push cylinder 42 drives the push piece 43 to move toward the annular body until the push piece 43 pushes the annular body to bend into place relative to the sheet body, and the straight push cylinder 42 is reset; the fifth step, the bent terminal continues to rotate with the rotating disk 2, and moves from the bending station 211 to the unloading station 212, which is equipped with an unloading plate The loosening cylinder 44 of 45 is started, and the unloading plate 45 presses one end of the corresponding clamping rod 23 toward the center of the turntable 2, and the other end of the clamping rod 23 releases the terminal, and the bent terminal falls onto the workbench 1 to be collected, and then the loosening cylinder 44 equipped with the unloading plate 45 is reset, and the corresponding clamping rod 23 is restored to the initial state; repeating the above steps, the terminals can be bent and collected one by one. Further explanation, the loosening cylinder 44 drives the unloading plate 45 or the loading plate 46 to press one end of the clamping rod 23 and force the torsion spring or spring to deform. The force required is much greater than the force generated when the pusher 43 pushes the annular body to bend relative to the sheet body, so that the clamping rod 23 can be prevented from rotating relative to the fixed block 22 when the terminal is bent;

[0026] Compared with the existing technology, this design can realize automatic loading, individual processing and collection of terminals, with a high degree of automation and high processing efficiency, effectively reducing labor costs.

[0027] As a specific implementation of the improvement, since the pusher 42 bends the terminal into place at one time, it is easy for the terminal to be subjected to large force and large deformation and breakage. At the same time, the terminal will be slightly moved when it is loaded onto the loading station 213 and rotates with the turntable 2, resulting in different states of the ring body after being bent relative to the sheet body due to different force points when the pusher 42 pushes the ring body, which will increase the number of unqualified terminals. In order to solve the above-mentioned problems, refer to Figure 4 As shown, the bending assembly 4 also includes an auxiliary push member 47, and the multiple stations 21 also include an initial bending station 214 located before the bending station 211 and corresponding to the auxiliary push member 47. The auxiliary push member 47 is positioned on one side of the push member 43 and is fixedly connected to the output shaft of the direct push cylinder 42. The auxiliary push member 47 is arranged corresponding to the initial bending station 214, and an alignment groove 48 for partially accommodating the terminal is arranged on the end of the auxiliary push member 47 facing the initial bending station 214. The alignment groove 48 is a V-shaped groove. During the processing, the terminal at the loading station 213 will first move to the initial bending station 214, and the direct push cylinder 42 will drive the push member 43 and the auxiliary push member 47 to move toward the turntable 2, and the annular body part of the terminal will first enter the alignment groove 48 and align with the alignment groove 48. The inner wall of the positioning groove 48 touches the ring body, and the annular body is bent at a certain angle relative to the sheet body, and then the straight-push cylinder 42 is reset. After the terminal that has been initially bent moves to the bending station 211, the straight-push cylinder 42 drives the push piece 43 and the auxiliary push piece 47 to move toward the turntable 2, and the push piece 43 will further push the annular body to bend into place relative to the sheet body, and then the straight-push cylinder 42 is reset. Such a design can be calibrated with the annular body through the V-shaped positioning groove 48, and the sheet body part of the terminal is slightly moved relative to the plane of the turntable 2, so that the subsequent push piece 43 can accurately bend the terminal; the auxiliary push piece 47 initially bends the terminal at a certain angle, so that the subsequent push piece 43 can quickly and gently bend the terminal into place, greatly reducing the situation where the terminal is easy to break, and improving the yield rate.

[0028] As a specific implementation method of the improvement, refer to Figure 4 As shown, the end face of the push piece 43 used to push and bend the terminal is an arc surface that can slide relative to the outer wall of the terminal. Compared with the design in which the end face of the push piece 43 is perpendicular to the horizontal plane, this design utilizes surface sliding instead of line-surface sliding, thereby reducing the wear between the push piece 43 and the annular body and ensuring the stability of the terminal structure.

[0029] As a specific implementation method of the improvement, refer to Figure 3 and Figure 4 As shown, a drop opening 11 is provided on the surface of the workbench 1 for the terminals dropped from the unloading station 212 to pass through, and a part of the turntable 2 can also pass through the drop opening 11. A collection box is arranged under the surface of the workbench 1 to facilitate the collection of the terminals. Such a design can further reduce the height of the turntable 2 relative to the surface of the workbench 1, thereby reducing the size requirements and installation space requirements of other related components, and effectively reducing the assembly cost of the utility model.

[0030] As a specific implementation method of the improvement, due to the difference in the quality of the terminal itself, there is a phenomenon that the terminal breaks when it is bent, and the fallen ring body will be scattered in various places on the workbench 1, which is not easy to clean and easily causes jamming of other parts. In order to solve the above-mentioned problem, refer to Figure 1 and Figure 2 As shown, a collection box 6 for receiving waste generated by terminal breakage is provided above the driver 3. Such a design can immediately receive the annular body collapsed due to the breakage in the collection box 6 for subsequent cleaning.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
