[0032] The utility model will be further described in detail below in combination with the embodiments in the drawings.

[0033] As Figures 1 to 4 shown, a specific embodiment of the plug bending mechanism of the utility model.

[0034] As Figure 1 and Figure 2As shown, the plug bending mechanism of the embodiment includes a bending mechanism frame 10, a plug clamping mechanism 20 clamping the plug, and a plug rotating driving mechanism 30 provided on the bending mechanism frame 10; the plug rotating driving mechanism 30 is provided with a rotating shaft 31, a rotating gear 32, and a moving rack 33; the rotating shaft 31 is rotatably connected to the bending mechanism frame 10 through two bearings and bearing seats; one end of the rotating shaft 31 is connected to the plug clamping mechanism 20; the rotating gear 32 is connected between the two bearings on the rotating shaft 31; the rotating gear 32 is engaged with the moving rack 33; and the moving rack 33 is vertically provided on the bending mechanism frame 10 and moves up and down back and forth.

[0035] The plug rotating driving mechanism 30 described above can also be provided with a rotating shaft 30 connected with a rotating power source; the rotating shaft 30 is rotatably connected to the bending mechanism frame 10 and one end of the rotating shaft 30 is connected to the plug clamping mechanism 20. The rotating shaft is driven to rotate by the rotating power source such as a motor, so as to realize the rotation of the clamping mechanism and drive the bending of the plug. The specific structure of the rotating driving mechanism can be realized by different rotating power sources and transmission mechanisms, and is not limited to the above two ways.

[0036] As shown in Figure 1 and Figure 5 , the semi-finished power plug B conveyed from the product production line C is clamped by the clamp A at the rear part of the power cord and is moved to the plug bending station and is clamped by the plug clamping mechanism 20. The moving rack 33 moves back and forth to drive the rotating gear 32 and the rotating shaft 31 to reverse, and then the rotating shaft 31 drives the plug clamping mechanism 20 to rotate, so as to finally realize the bending of the plug. The moving distance of the moving rack 33 is set to ensure that the included angle between the plug and the power cord reaches the requirement. The plug bending mechanism and the plug injection molding line solve the technical problem that the automatic equipment replaces the manual bending of the power cord, improve the production efficiency, and save the labor cost.

[0037] As shown in Figure 6 , the initial state of the plug is that the power cord is horizontally arranged with the plug blade or pin. After the plug is bent by the plug bending mechanism described above, the state of the plug becomes as shown in Figure 7 , that is, the power cord is vertically arranged with the plug blade or pin.

[0038] As shown in Figure 1 and Figure 2 , the plug bending mechanism further includes a plug cord pressing positioning mechanism 40 provided at the bottom of the bending mechanism frame 10 and driving the bending mechanism frame 10 to move along the axial direction of the power cord.

[0039] The plug wire pressing positioning mechanism 40 moves the bending mechanism frame 10 in the axial direction of the power cord, and when moving in the direction of the power cord, the corresponding plug clamping mechanism 20 moves simultaneously, and the clamped plug is pressed in the direction of the power cord, realizing the positioning of the bent plug. The moving distance is very small, and the purpose of pressing and positioning between the plug and the power cord is achieved.

[0040] As shown in Figure 1 and Figure 2 , the plug wire pressing positioning mechanism 40 includes a base plate 41, a linear guide rail assembly 42, a ball screw assembly 43, and a motor 44. The bending mechanism frame 10 is arranged on the base plate 41 through the linear guide rail assembly 42, and the motor 44 is arranged on the base plate 41 and connected to the bending mechanism frame 10 through the ball screw assembly 43.

[0041] The movement of the bending mechanism frame 10 on the base plate 41 is realized through the linear guide rail assembly 42. The action and movement distance are realized by driving the ball screw assembly 43 through the motor 44, which is high in precision and reliable in action.

[0042] As shown in Figure 1 and Figure 2 , the plug bending mechanism further includes a plug up-down positioning mechanism 50 for clamping the plug blade or pin. The plug up-down positioning mechanism 50 positions the plug by clamping the plug blade or pin. During the conveying process, the plug clamped by the clamp may occasionally deviate in position. The plug up-down positioning mechanism 50 clamps the plug blade or pin to reposition the plug, and then the plug clamping mechanism 20 clamps the left and right sides of the plug blade to ensure the accurate position of the plug and the power cord during subsequent plug bending.

[0043] As shown in Figure 1 and Figure 2 , the plug up-down positioning mechanism 50 includes an upper positioning block 51, an upper moving cylinder 52, a lower positioning block 53, and a lower moving cylinder 54. The upper positioning block 51 has a vertical clamping groove 51a, and the lower positioning block 53 has a V-shaped clamping groove 53a. The vertical clamping groove 51a matches the ground blade or pin on the plug, and the V-shaped clamping groove 53a matches the zero line and the fire line blade or pin on the plug. The upper moving cylinder 52 is arranged on the plug clamping mechanism 20, and its piston rod is connected to the upper positioning block 51. The lower moving cylinder 54 is arranged on the bending mechanism frame 10, and its piston rod is connected to the lower positioning block 53.

[0044] The plug up-down positioning mechanism 50 moves the upper positioning block 51 downward through the upper moving cylinder 52 to clamp the vertical clamping groove 51a into the ground blade or pin of the plug, and moves the lower positioning block 53 upward through the lower moving cylinder 54 to clamp the V-shaped clamping groove 53a into the zero line and fire line blade or pin of the plug, thereby positioning the up-down and left-right positions of the plug.

[0045] As shown in Figure 1 and Figure 2 , the plug rotating drive mechanism 30 includes a rack drive cylinder 34, the piston rod of which is connected to one end of the moving rack 33. The moving rack 33 is moved back and forth by the rack drive cylinder 34, thereby driving the rotation of the rotating gear 32 and the rotating shaft 31, which is simple in structure and low in action implementation cost.

[0046] As shown in Figure 1 and Figure 2 , the plug rotating drive mechanism 30 includes a drive mechanism moving cylinder 35 that drives it to move up and down, which is arranged on the bending mechanism rack 10 and has its piston rod connected to the plug rotating drive mechanism 30. The plug rotating drive mechanism 30 is moved up and down by the drive mechanism moving cylinder 35, so that the power plug on the production line is conveyed in front of the bending mechanism station, and the plug clamping mechanism 20 is driven by the plug rotating drive mechanism 30 to move up as a whole, thereby leaving a position for the power plug.

[0047] As shown in Figure 1 and Figure 2 , the plug clamping mechanism 20 includes a pneumatic finger 21, a left clamping jaw 22 and a right clamping jaw 23, which are respectively connected to the left and right sides of the pneumatic finger 21. The left and right clamping jaws 22 and 23 are clamped to the left and right sides of the plug base sheet by the pneumatic finger 21, and the power cord at the rear of the plug is clamped by the clamp, i.e. the power cord is horizontally fixed and immovable, so that the plug rotating drive mechanism 30 can bend the plug.

[0048] The action process of the plug bending mechanism is as follows:

[0049] 1. The drive mechanism moving cylinder 35 drives the plug rotating drive mechanism 30 and the plug clamping mechanism 20 to move up as a whole, while the lower moving cylinder 54 drives the lower positioning block 53 to move down, and then the semi-finished power plug is conveyed from the product production line, and the power cord at the rear of the plug is clamped by the clamp, as shown in Figure 3 or Figure 4 ;

[0050] 2. The upper moving cylinder 52 drives the upper positioning block 51 to move down, while the lower moving cylinder 54 drives the lower positioning block 53 to move up, thereby positioning the plug;

[0051] 3. The pneumatic finger 21 drives the left and right clamping jaws 22 and 23 to clamp the left and right sides of the plug base sheet;

[0052] 4. The upper moving cylinder 52 drives the upper positioning block 51 to move up, while the lower moving cylinder 54 drives the lower positioning block 53 to move down, thereby releasing the plug up and down, as shown in ​ ;

[0053] 5. The rack and pinion driven cylinder 34 drives the moving rack 33 to move down a set distance, the rotating gear 32 drives the rotating shaft 31 to rotate, thereby driving the plug clamping mechanism 20 to rotate, realizing the bending of the plug, so that the angle between the plug and the power cord reaches the set requirement, such as... ​ As shown;

[0054] 6. The motor 44 of the plug clamping and positioning mechanism 40 drives the ball screw assembly 43 to move, driving the bending mechanism frame 10 to move horizontally a set distance towards the power cord side. That is, the plug clamping mechanism 20 clamps the plug and squeezes the power cord, realizing the clamping and positioning between the plug and the power cord. At this point, the power plug's action at the plug bending station is completed, and all mechanism actions are reset to the state of step 1, waiting for the next power plug to be bent. The bent power plug is then conveyed to the next process through the production line.

[0055] In addition, the plug bending mechanism has another embodiment. Based on the above embodiment, the drive mechanism moving cylinder 35 is eliminated. The first step of the above action process can be achieved by the motor 44 of the plug wire clamping and positioning mechanism 40 driving the bending mechanism frame 10 to move backward to avoid the movement space of the power plug coming from the production line.

[0056] This utility model also discloses a plug injection molding line, including any of the above-mentioned plug bending mechanisms.

[0057] The plug bending mechanism and plug injection molding line use automated equipment to replace manual bending of the power cord, ensuring high precision in the bending angle between the power cord and the plug; at the same time, it improves production efficiency and saves labor costs.

[0058] In summary, as described in the specification and figures, this utility model has been manufactured into actual samples and subjected to multiple use tests.
