[0019] The following is in conjunction with the appendix Figure 1-7 The embodiments of the present invention will be described in detail.

[0020] A stamping and feeding device for a wire box includes a first conveyor rail 1 and a second conveyor rail 2 arranged in parallel. The first conveyor rail 1 includes a mounting frame 15 with two conveyor belts 17 mounted on it. A drive roller 16 is installed inside each conveyor belt 17. A support frame 20 is connected to the mounting frame 15, and a support roller 21 is rotatably mounted on the support frame 20. The support roller 21 and the conveyor belts 17 form a 90-degree angle. The second conveyor rail 2 includes a second mounting frame 24 with a second conveyor belt 26 mounted on it. A drive roller 25 is installed inside each conveyor belt 26. A support frame 25 is connected to the second mounting frame 24. 7. A support roller 28 is rotatably mounted on the support frame 27. The support roller 28 and the conveyor belt 26 form a 90-degree angle. The support roller 1 21 and the support roller 28 form a 90-degree angle. A bearing seat 22 is connected to the support frame 1 20. One end of the support roller 1 21 is connected to a rotating shaft, which is rotatably mounted inside the bearing seat 22. A rotating seat 23 is mounted on the support roller 1 21. The end of the support roller 1 21 away from the bearing seat 22 is rotatably mounted on the rotating seat 23. The end of the support roller 1 21 away from the bearing seat 22 is rounded. The support roller 28 is mounted on the support frame 27 in the same manner as the support roller 1 21.

[0021] A baffle bar 3 is provided at the middle position of the conveyor rail 1. A light sensor 4 and a pushing mechanism 5 are provided on the conveyor rail 1 behind the baffle bar 3. The pushing mechanism 5 includes a hydraulic cylinder 18 located inside the mounting frame 15 and a hydraulic cylinder 29 located outside the mounting frame 15. The hydraulic cylinder 18 is located between two transmission rollers 16. A push block 19 is connected to the piston rod of the hydraulic cylinder 18. A push block 20 is connected to the piston rod of the hydraulic cylinder 29. A hydraulic cylinder 31 is provided inside the piston rod of the hydraulic cylinder 29. The piston rod of the hydraulic cylinder 31 extends into the push block 20 and is connected to the push block 32. A groove is provided on the push block 20 to accommodate the push block 32.

[0022] Because the angle between the conveyor belt 17, the support roller 21, and the horizontal plane is 45 degrees (screw slider 2), after the wire box falls onto the conveyor rail 1, its side will contact the conveyor belt 17 and the support roller 21. The conveyor belt 17 propels the wire box forward, while the support roller 21 supports it. When the wire box moves correctly on the conveyor rail 1, the stop bar 3 will not obstruct it, and the wire box will pass under the stop bar 3. If the wire box is not positioned correctly, and its upper part is higher than the mounting bracket 15, it will be blocked by the stop bar 3. The wire box blocked by the stop bar 3 will block the light sensor 4, causing the light sensor 4 to emit a corresponding signal. Hydraulic cylinders 18 and 29 receive the signal and control their piston rods to extend, thereby moving push blocks 19 and 30. Push blocks 19 and 30 push the wire box away from the conveyor belt 17 and rise along the support roller 21. Once the wire box rises above the support roller 21, the hydraulic cylinder 31 extends its piston rod, causing the pusher block 32 to move. The pusher block 32 pushes the wire box, causing it to rotate on the rotating seat 23 and finally fall onto the conveyor rail 2. When a wire box that is incorrectly positioned on conveyor rail 1 is pushed onto conveyor rail 2, it will rotate 90 degrees, maintaining the same position as on conveyor rail 1, thus correcting the position.

[0023] A first feeding platform 6 and a second feeding platform 8 are respectively provided in front of the first feeding platform 1 and the second feeding platform 2. A vertical feeding belt 7 is provided in front of the first feeding platform 6, and several conveying rollers 9 are provided in front of the second feeding platform 8. A horizontal feeding belt 10 is provided in front of the conveying rollers 9, and a discharge belt 13 is provided in front of the vertical feeding belt 7. A flipping mechanism 12 is provided between the vertical feeding belt 7 and the discharge belt 13.

[0024] The wire box on conveyor rail 1 slides down the unloading platform 6 onto the vertical feed belt 7, and is then conveyed forward by the vertical feed belt 7. The wire box on conveyor rail 2 slides down the unloading platform 8 onto the conveyor roller 9, and is then conveyed forward by the conveyor roller 9 onto the transverse feed belt 10. The transverse feed belt 10 then conveys the wire box to the left, so that it reaches the vertical feed belt 7, where it is then conveyed by the vertical feed belt 7. A buffer block 11 is provided on the left side of the vertical feed belt 7, opposite to the transverse feed belt 10. The buffer block 11 is used to offset the impact of the wire box conveyed from the transverse feed belt 10 onto the vertical feed belt 7, preventing damage to the wire box.

[0025] A material-pushing mechanism 14 is provided on the side of the vertical feed belt 7. The material-pushing mechanism 14 includes a base 33, in which a lead screw 35 is rotatably mounted. A lead screw motor 34 is mounted on the base 33, and the motor shaft of the lead screw motor 34 is drivenly connected to the lead screw 35. A lead screw slider 36 is mounted on the lead screw 35, and a cylinder 3 is mounted on the lead screw slider 36. A mounting block 37 is connected to the right side of the piston rod of the cylinder 3, and a material-pushing rod 38 and a material-pushing rod 39 are connected to the right side of the mounting block 37. The lead screw motor 34 drives the lead screw 35 to rotate, thereby driving the lead screw slider 36 to move more forcefully, thus moving the lead screw slider 36. The cylinder 3 controls the extension of its piston rod, driving the material-pushing rods 38 and 39 to move to the right, thereby pulling the wire box on the vertical feed belt 7 onto the flipping mechanism 12 and then pulling the wire box on the flipping mechanism 12 onto the discharge belt 13.

[0026] The flipping mechanism 12 includes a base 47, with a cylinder 48 mounted on the upper part of the base 47. A mounting base 49 is connected to the piston rod of the cylinder 48, and a rotary motor 53 is mounted on the mounting base 49. A fixed base 52 is mounted on the upper part of the mounting base 49, and the lower part of the rotary motor 53 is locked into the fixed base 52 for fixation. A rotating disk 40 is connected to the motor of the rotary motor 53. A bracket 46 and a bracket 41 are respectively located on the left and right sides of the base 47. A flipping mechanism 55 is mounted on both brackets 46 and bracket 41. The two flipping mechanisms 55 are at the same height and are arranged opposite each other. The flipping mechanism 55 on bracket 41 is installed in a fixed block 54 connected to bracket 41. A hydraulic cylinder 42 is mounted on the upper part of bracket 41 and is located at the center of the rotating disk 40. Directly above, the lower end of the piston rod of hydraulic cylinder 42 is connected to a mounting plate 59. A pressure block 60 is set below the mounting plate 59. Guide rods 62 are connected to the upper left and right sides of the pressure block 60. The upper end of the guide rods 62 extends out of the mounting plate 59 and is connected to a limit block 63. A spring 64 is sleeved on the part of the guide rods 62 that extends out of the mounting plate 59. The upper end of the spring 64 is connected to the lower part of the limit block 63, and the lower end of the spring 64 is connected to the upper part of the mounting plate 59. A pressure sensor 61 is set below the mounting plate 59. Hydraulic cylinder 65 is set on bracket 41. The lower end of the piston rod of hydraulic cylinder 65 is connected to a sleeve 66. A pressure rod 67 is set inside the sleeve 66. A spring 68 is connected between the pressure rod 67 and the sleeve 66. A pressure sensor 69 is set inside the sleeve 66. The sleeve 66 has grooves 70 on both the left and right sides of the pressure rod 67. Guide blocks 71 are provided on both the left and right sides of the pressure rod 67. The guide blocks 71 are located in the grooves 70. The pressure rod 67 is limited by the cooperation of the guide blocks 71 and the grooves 70, so that it rises and falls in the specified direction.

[0027] The junction box is moved to the top of the rotating disk 40, aligning its center with the center of the rotating disk 40. Hydraulic cylinder 42 extends its piston rod, causing the mounting plate 59 to descend a certain distance. If the junction box on the rotating disk 40 is facing upwards, the pressure block 60 enters the opening of the junction box, preventing the pressure sensor 61 from being triggered. If the junction box is facing downwards, the pressure block 60 presses against the bottom of the junction box. As the mounting plate 59 continues to descend, the pressure block 60 contacts the pressure sensor 61, triggering it. When the junction box is facing downwards, adjustment is required. Cylinder 56 extends its piston rod, causing the clamping blocks 58 to move inwards, clamping the junction box between the two sides. Cylinder 48 retracts its piston rod, causing the rotating disk 40 to descend, disengaging the junction box from the rotating disk 40. The flipping motor 57 then controls the clamping block 58 to rotate, thereby causing the clamped wire box to rotate 180 degrees, so that the wire box is in an open-facing position. Then, the cylinder 48 controls its piston rod to extend, causing the rotating disk 40 to rise and support the wire box again, while the cylinder 56 controls its piston rod to retract, causing the clamping block 58 to leave the wire box.

[0028] When the wire box is facing upwards, hydraulic cylinder 5 (65) controls its piston rod to extend, causing sleeve 66 and pressure rod 67 to descend. If pressure rod 67 contacts the mounting post inside the wire box during its descent, it will be compressed and retract into sleeve 66. Pressure rod 67 then contacts pressure sensor 2 (69), triggering it. At this point, hydraulic cylinder 5 (65) first controls its piston rod to retract, causing pressure rod 67 to rise and leave the wire box. Then, rotary motor 53 drives rotary disk 40 to rotate 180 degrees, causing the wire box on rotary disk 40 to rotate 180 degrees to adjust its position. If the wire box is already in the correct position, pressure rod 67 will not be obstructed during its descent, and pressure sensor 2 (69) will not be triggered. By adjusting the position of the wire box, it is conveyed backwards in the required state, preparing for subsequent wire box stamping.

[0029] The upper part of the bracket 2 41 is equipped with a lead screw motor 2 43 and a lead screw 2 44. The motor shaft of the lead screw motor 2 43 is drivenly connected to the lead screw 2 44. The lead screw 2 44 is equipped with a lead screw slider 2 45. The hydraulic cylinder 5 65 is installed at the lower part of the lead screw slider 2 45.

[0030] The lead screw motor 43 drives the lead screw 44 to rotate, which in turn moves the lead screw slider 45 left and right, thereby adjusting the position of the pressure rod 67 to correspond with the position of the mounting post in the junction box. This allows for adaptive adjustment based on the position of the mounting post in different models of junction boxes, increasing the range of applications.

[0031] A guide rod 50 is connected to the upper part of the base 47. The guide rod 50 passes through the mounting base 49, and its upper end protrudes from the mounting base 49 and is connected to a limit block 51. The guide rod 50 is used to guide the lifting and lowering of the mounting base 49 to ensure the vertical lifting and lowering of the mounting base 49.
