DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 To Attachment Figure 10 This application is described in further detail.

[0028] In order to improve the deficiencies of low automation and low efficiency in the existing technology. An embodiment of the present application discloses a copper terminal punching machine, which includes: a punching module 1, a lifting module 2, a conveying module 3, a transition module 4, a receiving module 5 and a pushing module 6. The punching module 1 includes a punching machine body and components used by the related punching machine, and is used for punching copper parts to form copper terminals, which belongs to the prior art and will not be elaborated here. For the convenience of description, the position where the punching module 1 places the copper parts is called the feeding port. The lifting module 2 is spaced apart from the side of the punching die and is placed on the ground surface. The lifting module 2 includes a storage box 21, a lifting housing 22, a plurality of fixing plates 23 and a plurality of lifting plates 24. A large number of copper parts are poured into the storage box 21 at one time for standby. The lifting housing 22 extends upward from the edge of the storage box 21. The lifting housing 22 includes two outer edges on both sides and a back plate arranged in the direction perpendicular to the ground, forming a trapezoidal hopper-like structure. The fixing plates 23 and the lifting plates 24 are arranged in the lifting housing 22. The fixing plates 23 are fixedly connected to the lifting housing 22, and the lifting plates 24 are slidably connected to the lifting housing 22. The fixing plates 23 and the lifting plates 24 are both vertically arranged, and the fixing plates 23 and the lifting plates 24 are arranged parallel to the back plate. A plurality of fixing plates 23 and a plurality of lifting plates 24 are all parallel to each other and arranged in a stepped manner, that is, the upper surface of the fixing plate 23 close to the storage box 21 among two adjacent fixing plates 23 is lower than the upper surface of the fixing plate 23 far from the storage box 21, and the same is true for the lifting plate 24. A plurality of fixing plates 23 and a plurality of lifting plates 24 are alternately arranged in sequence, that is, taking the position where the storage box 21 is located as the front and the position far from the storage box 21 as the back, the lifting plate 24 is arranged behind the fixing plate 23, and then another fixing plate 23 is arranged behind it, and so on. Each lifting plate 24 is slidably connected between two adjacent corresponding fixing plates 23. The lifting plate 24 can start from the highest end of the previous fixing plate 23 and move to cross the highest end of the next fixing plate 23 after that. That is, the lifting plate 24 can lift the copper parts to the upper surface of the next-level fixing plate 23 and fall onto the upper end of the next-level lifting plate 24. The lifting module 2 further includes a lifting component 25 for driving a plurality of lifting plates 24 to move. The conveying module 3 includes a conveying channel 31, a conveyor belt 32 and a plurality of detection elements. The cross-section of the conveying channel 31 is concave. The conveying channel 31 is connected to the top of the lifting housing 22 and horizontally extends in the direction of the punching module 1. The conveying channel 31 is arranged perpendicular to the moving direction of the lifting plate 24. The conveyor belt 32 is circularly rotatably connected in the conveying channel 31 along the length direction of the conveyor belt 32. A plurality of detection elements are connected to the conveying channel 31 in sequence along the conveying path direction. The detection elements are set according to specific needs, such as infrared counting elements, appearance detection elements (cameras), etc., which belong to the prior art and will not be elaborated here. The transition module 4 includes a transition hopper 41 and a transition slideway 42. The transition hopper 41 is arranged below the end of the conveyor belt 32. The upper frame of the transition hopper 41 is wide at the top and narrow at the bottom and uniformly transitions, so that the copper parts falling into the transition hopper 41 are rotated from a horizontal state to a vertical state and fall. One end of the transition slideway 42 is connected to the bottom of the transition hopper 41, and the other end extends obliquely in the direction of the punching module 1.The transition hopper 41 and the transition chute 42 are supported below the conveying path 31 by brackets. The receiving module 5 includes a receiving platform 51, a receiving block 52, and a sliding driving member 53. The receiving platform 51 is arranged outside the feeding port of the stamping module 1. The receiving block 52 is slidably connected to the receiving platform 51. The receiving block 52 is provided with a through groove 521 that can communicate with the outlet end of the transition chute 42 after sliding with the receiving block 52. The cross-section of the through groove 521 is arch-shaped. A chute 511 is provided at a position corresponding to the feeding port of the stamping module 1 on the receiving platform 51, and the cross-section of the chute 511 is rectangular. The through groove 521 penetrates downward through the receiving block 52. The receiving block 52 can slide to connect the through groove 521 with the chute 511. The pushing module 6 includes a pushing rod 61 and a pushing element 62. The pushing rod 61 is arranged along the length direction of the chute. The pushing element 62 drives the pushing rod 61 to slide and penetrate into the chute 511. The lifting module 2 realizes the step-by-step lifting of the copper parts through the stepwise arranged lifting plates 24 and fixing plates 23, and the driving of the lifting assembly 25 (such as a lifting motor 251 and a cam disc 252). The conveying module 3 horizontally conveys the copper parts from the top of the lifting housing 22 to the stamping module 1 through the conveyor belt 32. The transition module 4 guides the copper parts at the end of the conveyor belt 32 to the receiving module 5 through the transition hopper 41 and the transition chute 42. The receiving block 52 in the receiving module 5 can slide under the drive of the sliding driving member 53 to connect the through groove 521 with the outlet end of the transition chute 42, and then with the chute 511 at the position corresponding to the feeding port of the stamping module 1, allowing the copper parts to fall in. The stamping module 1 performs stamping processing on the copper parts. In this way, a smooth transition of the copper parts from the conveyor belt 32 to the stamping module 1 is achieved, avoiding damage to the copper parts during the transfer process. This combination ensures that the copper parts can be smoothly and orderly lifted from the storage box 21 and conveyed to the stamping module 1, improving production efficiency and reducing the tediousness of manual operation. Both the pushing element 62 and the sliding driving member 53 are telescopic cylinders.

[0029] Further, the bottoms of several lifting plates 24 are connected by a connecting plate 242. The lifting assembly 25 includes a lifting motor 251 and a cam disc 252. The output end of the lifting motor 251 is eccentrically connected to the cam disc 252, and the edge of the cam disc 252 abuts against the lower surface of the connecting plate 242. The output end of the lifting motor 251 is perpendicular to the moving direction of the lifting plate 24. By the rotation of the cam disc 252, several lifting plates 24 are lifted at the highest point and reset when the cam disc 252 rotates to the lowest point.

[0030] Further, a chamfer 241 is provided at the top of the lifting plate 24. The chamfer 241 is inclined towards the conveying path 31. The provision of the chamfer 241 inclined towards the conveying path 31 at the top of the lifting plate 24 helps the copper parts to smoothly slide down to the next-level fixing plate 23 or the conveyor belt 32 during the lifting process. The jamming and accumulation of copper parts during the lifting process are reduced, and the running smoothness of the equipment is improved.

[0031] Since metal particles or other impurities are likely to adhere to the surface of the copper parts, during stamping, these impurities will form depressions on the surface of the copper parts along with the stamping, resulting in a decline in the quality of the finished copper terminals. Therefore, the copper terminal punching machine of this application further includes a grinding module 7 for grinding the impurities on the surface of the copper parts. A switching groove 512 is formed in the receiving platform 51. The switching groove 512 is a horizontally flat rectangular groove structure, and the switching groove 512 penetrates the receiving platform 51 in the direction of the stamping module 1. The switching groove 512 communicates with the sliding groove 511. The grinding module 7 includes a control board 71, a grinding roller 72, and a grinding driving member 73. A grinding groove 711 is formed on the control board 71 along the direction of the sliding groove 511, and the grinding roller 72 rotates in the grinding groove 711. The control board 71 slides in the switching groove 512, and the grinding roller 72 can enter the sliding groove 511 after sliding with the control board 71. The grinding driving member 73 is connected to the control board 71 to drive the grinding roller 72 to rotate. The grinding driving member 73 is a motor. The grinding roller 72 adopts a wool roller structure. The grinding module 7 grinds the copper parts falling into the sliding groove 511 through the grinding roller 72 in the grinding groove 711 on the control board 71. The grinding driving member 73 drives the grinding roller 72 to rotate, and at the same time, the control board 71 can slide in the switching groove 512 to make the grinding roller 72 enter or leave the sliding groove 511. The smoothness of the surface of the copper parts is increased, and the product quality is improved. The flexible switching design of the grinding module 7 also meets the flexibility under different production requirements.

[0032] Further, the grinding module 7 further includes a stop block 74, and the stop block 74 is located between the stamping module 1 and the receiving platform 51. The coverage range of the side surface of the stop block 74 is greater than or equal to the cross-sectional range of the sliding groove 511. The stop block 74 is connected to the control board 71 and moves together with the control board 71. The stop block 74 can move to the end of the sliding groove 511 close to the stamping module 1 and form a closure for this end.

[0033] Further, a groove 741 is formed in the stop block 74 along the length direction of the sliding groove 511. A cylindrical end post 75 is rotatably connected in the groove 741. The end post 75 includes a synchronous section 751 and an abutting section 753. The abutting section 753 faces the sliding groove 511. The synchronous section 751 is located in the groove 741. A synchronous gear 721 is coaxially connected to the grinding roller 72. Synchronous teeth 752 are provided on the outer peripheral side of the synchronous section 751. The synchronous gear 721 meshes with the synchronous teeth 752.

[0034] Further, the end post 75 is also slidably connected in the groove 741 along the length direction of the sliding groove 511. A reset elastic element 76 is provided in the groove 741 to make the end of the abutting section 753 of the end post 75 always flush with the surface of the stop block 74. In order to further make it easier for the copper parts to enter the groove 741, an inclined angle can be annularly provided at the edge of the groove 741. A limiting groove 742 is formed on the inner wall of the groove 741, and a limiting ring 754 that can slide in the limiting groove 742 is provided on the outer wall of the end post 75.

[0035] Since the stopper 74 is connected to the control board 71 and can move to the end of the chute 511, it can cooperate with the pushing rod 61 to clamp the copper part to prevent the copper part from slipping out of the chute 511 during the grinding process. The end post 75 is rotatably connected in the groove 741, and the end post 75 and the chute 511 are coaxial. The end post 75 includes a synchronous section 751 and an abutting section 753. The synchronous section 751 is rotatably connected to the stopper 74, and the abutting section 753 is used to abut against the copper part. When the copper part is pressed against the end post 75, the copper part can rotate coaxially with the end post 75, that is, the copper part rotates self. The synchronous teeth 752 on the outer peripheral side of the synchronous section 751 are engaged with the synchronous gear 721 coaxially connected to the grinding roller 72 to achieve synchronous and reverse rotation. The design of the stopper 74 enhances the safety of the equipment and prevents the accidental slipping of the copper part. The meshing design of the end post 75 and the synchronous gear 721 ensures the synchronous rotation of the grinding roller 72 and the end post 75, improving the grinding efficiency. The end post 75 is slidably connected in the groove 741 along the length direction of the chute 511, and the reset elastic element 76 makes the end of the abutting section 753 of the end post 75 always flush with the surface of the stopper 74. This design allows the end post 75 to be finely adjusted according to the size and position of the copper part, ensuring the uniformity and consistency of grinding. The addition of the reset elastic element 76 enhances the adaptability and stability of the end post 75. And when the copper part is pushed against the end post 75, it can be inserted into the groove 741 inward, thereby further enhancing the stability of the copper part during grinding. The cooperation of the limiting groove 742 and the limiting ring 754 limits the rotation range of the end post 75, preventing the end post 75 from rotating excessively or falling off during the grinding process, and improving the safety and stability of the equipment.

[0036] Further, due to the limited clearance distance between the stamping module 1 and the receiving platform 51, it is necessary to optimize the position of the grinding driving member 73 to compress this clearance as much as possible. Specifically, a connecting strip 522 is provided at one end of the receiving block 52 close to the stamping module 1. The connecting strip 522 is a hollow structure. The connecting strip 522 extends downward to the lower end of the receiving platform 51 and is provided with a translation plate 524. The translation plate 524 is slidably connected to the lower surface of the receiving platform 51. The housing of the grinding driving member 73 is fixedly connected to the side of the translation plate 524 facing away from the receiving platform 51, and the output end of the grinding driving member 73 faces the stamping platform. It is used to provide support for the copper part in the clearance after grinding is completed, so that the pushing rod 61 can smoothly push the copper part into the stamping module 1. A first driving wheel 731 is coaxially arranged at the output end of the grinding driving member 73. An extension strip 523 is provided at the same horizontal position as the grinding roller 72 in the connecting strip 522. The upper wall of the part of the extension strip 523 between the stop block 74 and the receiving block 52 is flush with the inner wall of the bottom of the sliding groove 511. A first rotating shaft 54 is provided at the intersection of the extension strip 523 and the connecting strip 522. A second driving wheel 541 and a third driving wheel 542 are coaxially arranged on the first rotating shaft 54. A fourth driving wheel 722 is coaxially arranged on the grinding roller 72. The first driving wheel 731 and the second driving wheel 541 are driven by a first synchronous belt 543. The third driving wheel 542 and the fourth driving wheel 722 are driven by a second synchronous belt 544. The first driving wheel 731 and the second driving wheel 541 are driven by a first synchronous belt 543, and the third driving wheel 542 and the fourth driving wheel 722 are driven by a second synchronous belt 544, realizing the synchronous rotation between the grinding roller 72 and the driving wheel. By making the connecting strip 522 hollow and extending downward to the lower end of the receiving platform 51, a translation plate 524 is provided to install the grinding driving member 73. The first driving wheel 731 drives the second driving wheel 541 and the third driving wheel 542, and the second driving wheel 541 drives the fourth driving wheel 722 of the grinding roller 72 through the first synchronous belt 543, realizing the rotation of the grinding roller 72. While shortening the distance between the stamping module 1 and the receiving platform 51, the grinding driving member 73 can stably and efficiently drive the grinding roller 72 to rotate. At the same time, the design of the connecting strip 522 and the translation plate 524 also enhances the structural stability and reliability of the equipment. The grinding efficiency is improved, the synchronism between the grinding roller 72 and the driving wheel is ensured, and the wear and noise caused by the speed mismatch are reduced.

[0037] The implementation principle of a copper terminal punching machine in an embodiment of the present application is as follows: The lifting module 2 realizes the step-by-step lifting of the copper part through the lifting plates 24 and the fixing plates 23 arranged in a stepped manner, and the driving of the lifting assembly 25 (such as the lifting motor 251 and the cam disc 252). The conveying module 3 horizontally conveys the copper part from the top of the lifting housing 22 to the receiving module 5 through the conveyor belt 32. After alignment, the copper part is sent into the stamping module 1 by the pushing module 6 for stamping.

[0038] The receiving module 5 includes three states: First, the blanking state. The copper part is located in the receiving block 52 and moves with the receiving block 52 to above the chute 511, and the copper part falls into the chute 511. At this time, the copper part contacts the surface of the control board 71. Second, the grinding state. The receiving block 52 resets to continue receiving the next copper part. At this time, the grinding roller 72 moves with the control board 71 into the chute 511 to abut against the copper part. At the same time, the stopper 74 corresponds to the chute 511, and the pushing rod 61 moves to abut against the copper part and pushes the copper part into the groove 741. The grinding roller 72 starts, and the grinding roller 72 and the end post 75 rotate in opposite directions to grind the outer peripheral side of the copper part. Third, the pushing state. The pushing rod 61 withdraws from the chute 511. At the same time, when the end post 75 resets, the copper part is pushed out of the groove 741, the receiving block 52 is pushed, and the grinding roller 72 and the stopper 74 move away from the chute 511 accordingly. At this time, the stamping module 1 and the receiving platform 51 are connected through the extension bar 523, so that the pushing rod 61 smoothly sends the copper part into the stamping module 1, and the receiving block 52 continues to move until it is connected to the chute 511 again.

[0039] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
