[0039] As Figures 1 to 3 shown in the figure, this embodiment provides a terminal cutting device for cutting the connected terminals on the terminal strip 100 into individual terminals. The terminal cutting device includes a main body mechanism 1, a first driving member 2, a positioning mechanism 3 and a blanking mechanism 4. The main body mechanism 1 has a workbench 11, and a first guide rail 111 is provided on the tabletop of the workbench 11. The terminal strip 100 is laid along the first guide rail 111. When cutting the terminals, the terminal strip 100 will not shift in position, which is convenient for subsequent blanking work. The first driving member 2 and the positioning mechanism 3 are located below the workbench 11. The output end of the first driving member 2 is connected to the positioning mechanism 3. The orientation of the output end of the first driving member 2 is consistent with the laying direction of the first guide rail 111. Under the action of the first driving member 2, the positioning mechanism 3 can reciprocate along the extension direction of the first guide rail 111. Among them, the telescopic distance of the output end of the first driving member 2 is the length of one terminal.

[0040] As Figure 2 、 Figure 3 and Figure 6As shown, the positioning mechanism 3 includes a positioning pin assembly 31 and a second driving member 32. There is a through hole 101 in the terminal strip 100, and a first avoidance hole 112 is provided on the first guide rail 111. When the terminal strip 100 is laid on the first guide rail 111, the through hole 101 is opposite to the first avoidance hole 112. The output end of the second driving member 32 faces the first avoidance hole 112, and the positioning pin assembly 31 is connected to the output end of the second driving member 32. The positioning pin assembly 31 includes a positioning pin 311, and the positioning pin 311 faces the through hole 101. In this way, under the action of the second driving member 32, the positioning pin 311 can be selectively inserted through the first avoidance hole 112 into the through hole 101. When the output end of the second driving member 32 extends to insert the positioning pin 311 into the through hole 101, and then the output end of the first driving member 2 extends, the terminal strip 100 will move along the first guide rail 111. The positioning pin assembly 31 further includes a base, the base is fixedly arranged at the output end of the second driving member 32, and the positioning pin 311 is installed on the base and faces the through hole 101.

[0041] The blanking mechanism 4 is located on one side of the positioning mechanism 3 along the extending direction of the first guide rail 111. In this way, when the output end of the second driving member 32 extends the positioning pin 311 out of the first avoidance hole 112 and inserts it into the through hole 101, and then the output end of the first driving member 2 extends, the terminal strip 100 will be moved to the blanking mechanism 4. The blanking mechanism 4 includes a blanking pressure plate 41, a third driving member 42 and a blanking knife 43. There is a second avoidance hole 113 on the first guide rail 111. The blanking pressure plate 41 is placed on the workbench 11, and a blanking hole 411 is provided in the blanking pressure plate 41. The blanking hole 411 is opposite to the second avoidance hole 113. When the terminal strip 100 enters below the blanking pressure plate 41 along the first guide rail 111, the terminals on the terminal strip 100 will stay in the blanking hole 411. The third driving member 42 is located below the workbench 11, and the output end of the third driving member 42 faces the second avoidance hole 113. The blanking knife 43 is connected to the output end of the third driving member 42, and the blanking knife 43 faces the blanking hole 411. In this way, under the action of the third driving member 42, the blanking knife 43 can be selectively inserted through the second avoidance hole 113 and extend into the blanking hole 411. When the output end of the third driving member 42 extends, at this time the blanking knife 43 extends into the blanking hole 411, and at the same time the blanking pressure plate 41 presses against the terminal strip 100, and the terminals can be blanked out.

[0042] The working principle of the terminal cutting device is as follows: The output end of the second driving member 32 is extended, so that the positioning pin 311 extends into the through hole 101 on the terminal strip 100; The output end of the first driving member 2 is extended, driving the positioning mechanism 3 to move in the laying direction of the first guide rail 111, so that the terminal strip 100 enters below the punching hole 411 on the punching pressure plate 41; The output end of the third driving member 42 is extended, so that the punching knife 43 extends into the punching hole 411 to punch out the terminal, completing one-time terminal punching. Subsequently, the output end of the third driving member 42 is retracted, so that the punching knife 43 returns to its initial position; The output end of the second driving member 32 is retracted, so that the positioning pin 311 returns to its initial position, and the positioning pin 311 is away from the through hole 101; The output end of the first driving member 2 is retracted, driving the positioning mechanism 3 back to its initial position. At this time, the positioning pin 311 is located below the through hole 101 beside the next terminal on the terminal strip 100. Subsequently, the output end of the second driving member 32 is extended and the output end of the first driving member 2 is extended in sequence. Since the telescopic distance of the output end of the first driving member 2 is the length of one terminal, each time the first driving member 2 pushes the positioning mechanism 3 to move along the direction of the first guide rail 111, the terminal on the terminal strip 100 will enter the punching hole 411, and the output end of the third driving member 42 is extended to punch out the second terminal. By repeating the above process, the connected terminals on the terminal strip 100 can be punched into individual terminals.

[0043] In the terminal cutting device of this embodiment, by providing the first guide rail 111 on the workbench 11, the terminal strip 100 can move along the first guide rail 111, avoiding the problem of deviation when the terminal strip 100 moves, ensuring that the connected terminals on the terminal strip 100 can be accurately punched into individual terminals, and avoiding waste of resources. The first driving member 2, the positioning mechanism 3 and the punching mechanism 4 are all installed on the main body mechanism 1, and the first driving member 2, the positioning mechanism 3 and the punching mechanism 4 are arranged in sequence along the laying direction of the first guide rail 111 on the workbench 11. By the mutual cooperation of the three, the terminal can be punched out, making the structure of the terminal cutting device simpler and more miniaturized as a whole, avoiding the long-path transmission of the terminal strip 100, and effectively improving the working efficiency of the terminal cutting device.

[0044] In this embodiment, the first driving member 2, the second driving member 32 and the third driving member 42 can all be selected from one of an electric telescopic rod, a telescopic cylinder or a telescopic hydraulic cylinder, and no specific limitation is made here.

[0045] In this embodiment, a first guiding groove can be provided on the workbench 11, and the first guide rail 111 is arranged in the first guiding groove. In this way, the blanking pressing plate 41 can be made into a flat shape, and even when the blanking pressing plate 41 is attached to the workbench 11, it will not press the terminal strip 100, and the terminals cut out will not be deformed. Of course, the first guide rail 111 can also be directly laid on the surface of the workbench 11. At this time, a convex portion needs to be designed on the blanking pressing plate 41 so that the blanking pressing plate 41 will not press the terminal strip 100 to avoid deformation of the cut-out terminals.

[0046] In this embodiment, as Figure 1 shown in the figure, the terminal cutting device further includes a recycling box body 5. The recycling box body 5 has a recycling port facing the tail end of the first guide rail 111. After the terminals on the terminal strip 100 are cut out and ejected from the punching holes 411, they are adsorbed by the air suction component and transferred to the designated placement position by the robotic arm or adsorbed and stored in the storage cavity of the air suction component. The remaining waste will continue to move along the first guide rail 111 as the entire terminal strip 100 moves. The setting of the recycling box body 5 can recycle the waste generated after the terminal strip 100 is blanked, ensuring the cleanliness of the environment. By facing the recycling port towards the tail end of the first guide rail 111, the waste can directly enter the recycling box body 5 during the pushing process, eliminating the need for manual picking of the waste into the recycling box body 5 and making the design of the terminal cutting device more reasonable. The robotic arm holds the air suction component and drives the air suction component to move to carry the cut-out terminals. The air suction component includes a suction nozzle, an air suction pump, and a power supply. When the power supply is turned on to make the air suction pump in a working state, the suction nozzle can adsorb the cut-out terminals. For the specific structure and working principle of the air suction component and the robotic arm, reference can be made to the prior art, which is not the key protected content of this embodiment.

[0047] In this embodiment, as Figure 1 and Figure 7 shown in the figure, the terminal cutting device further includes a crimping component 6. The crimping component 6 is located at the head end of the first guide rail 111. The crimping component 6 includes a fixing member 61, a roller 62, and an elastic member. The roller 62 is mounted on the fixing member 61, and the elastic member is connected to the fixing member 61 and abuts against the surface of the roller 62. Under the action of the elastic member, the roller 62 always abuts against the surface of the terminal strip 100. In this way, when the output end of the second driving member 32 in the positioning mechanism 3 retracts to drive the positioning pin 311 to retract, and then the output end of the first driving member 2 retracts to drive the positioning mechanism 3 back to the initial position, even if the positioning pin 311 contacts the terminal strip 100, the terminal strip 100 will not move backward under the abutment of the roller 62, ensuring that the terminal strip 100 can cut out terminals each time it moves, and further improving the working efficiency of the terminal cutting device.

[0048] Regarding the fixing member 61, in this embodiment, the fixing member 61 includes a columnar body with a rectangular cross-section and a connecting pin. A first through-hole is provided in the center of the fixing member 61, and the roller 62 is placed in the first through-hole. The sidewalls of the first through-hole have positioning grooves. The connecting pin passes through the roller 62, with both ends inserted into the positioning grooves. There is a gap between the roller 62 and the top surface of the first through-hole. An elastic member is provided in the gap between the top surface of the first through-hole and the circumference of the roller 62 to ensure that the roller can always abut against the surface of the terminal strip 100. Preferably, the connecting pin is a flexible member.

[0049] In this embodiment, the elastic member can be a spring or a spring, and there are no specific limitations here. Regarding the crimping assembly 6, the fixing member 61 can also be assembled using a support platform composed of three mutually perpendicularly connected plates and a connecting pin. The support platform is placed on the top plate facing the terminal strip 100, and the roller 62 is placed in the middle space of the support platform. The connecting pin extends through and connects the two side plates 13 and the roller 62. The elastic member is connected to the top plate of the support platform and abuts the circumference of the roller 62.

[0050] In the present embodiment, the terminal cutting equipment further comprises a detection sensor, wherein the detection sensor is located between the first avoidance hole 112 and the second avoidance hole 113, and the detection sensor can detect whether the terminal strip 100 has been completely blanked. Specifically, the detection sensor will emit a detection light toward the terminal strip 100 to determine whether the terminal strip 100 exists in the area it illuminates. If the detection sensor does not detect the terminal strip 100, it proves that the section of the terminal strip 100 has been completely blanked. Preferably, the detection sensor has an alarm element. When the detection sensor does not detect the terminal strip 100, the alarm element issues a prompt to inform the staff to install a new terminal strip 100. The detection sensor can be attached to the first guide rail 111 and placed on the bottom surface of the terminal strip 100, or a detection sensor with a mounting frame can be selected and placed on the workbench 11, with the detection light directed toward the terminal strip 100. No specific restrictions are made here.

[0051] In this embodiment, Figures 1 to 3 As shown in , the positioning mechanism 3 also includes a positioning pressure plate 33, which is placed on the workbench 11 and abuts against the terminal strip 100. A third avoidance hole 331 is provided on the positioning pressure plate 33, and the third avoidance hole 331 is opposite to the first avoidance hole 112. In this way, when the positioning pin 311 in the positioning mechanism 3 passes through the through hole 101 and drives the terminal strip 100 to move, the terminal strip 100 will not be lifted under the action of the positioning pressure plate 33, and can smoothly enter the punching mechanism 4. The third avoidance hole 331 can also ensure that the positioning pin 311 is extended, ensuring that the positioning pin 311 can be used later.

[0052] As preferably, Figure 3 and Figure 4As shown in , the positioning mechanism 3 also includes a first guide member 34, which is connected to the output end of the first drive member 2, and the first guide member 34 is connected to the second drive member 32, wherein a guide groove is provided on the back of the workbench 11, the direction of the guide groove is consistent with the direction of the first guide rail 111, and the first guide member 34 is partially placed in the guide groove, so that when the output end of the first drive member 2 extends and pushes the positioning mechanism 3 to move toward the punching mechanism 4, the first guide member 34 and the guide groove can guide the movement of the output end of the first drive member 2, ensuring that the first drive member 2 can stably push the positioning mechanism 3. At the same time, the first guide member 34 has a first guide hole, and the positioning pin assembly 31 is movably provided in the first guide hole, so that when the output end of the second drive member 32 extends, the first guide hole can guide the movement of the output end of the first drive member 2, so that the positioning pin 311 can be more accurately inserted into the through hole 101 of the terminal strip 100, further improving the accuracy of the terminal cutting equipment.

[0053] Preferably, the positioning mechanism 3 further includes a second guide rail 35 and a guide groove 36, wherein the second guide rail 35 is laid on the back of the workbench 11, and the laying direction of the second guide rail 35 is consistent with the laying direction of the first guide rail 111, and the guide groove 36 is provided on the first guide member 34, and the guide groove 36 and the second guide rail 35 are slidably matched. Since the output end of the first driving member 2 is connected to the first guide member 34, the provision of the second guide rail 35 and the guide groove 36 can further guide the extension of the output end of the first driving member 2, further improve the accuracy of the moving direction of the positioning mechanism 3, enable the terminal strip 100 to accurately enter the blanking mechanism 4, reduce the blanking error rate of the terminal cutting equipment, and further reduce the waste of the terminal strip 100 during the blanking process.

[0054] As preferably, Figure 3 and Figure 5 As shown in , the blanking mechanism 4 further includes a second guide member 44, wherein the second guide member 44 is connected to the back of the workbench 11 and has a second guide hole. The blanking blade 43 is movably disposed in the second guide hole. Thus, when the output end of the third driving member is extended, the blanking blade 43 moves along the second guide hole, which can guide the direction of movement of the blanking blade 43, further ensuring that the blanking blade 43 can accurately extend into the blanking hole 411, thereby accurately blanking the terminal strip 100 to punch out the terminals.

[0055] In this embodiment, the punching plate 41 has a punching blade that faces the terminal strip 100. Specifically, the punching blades are disposed on the sidewalls of the punching hole 411 at both ends of the punching hole 411 along the direction in which the first guide rail 111 is laid. When the punching knife 43 extends through the punching hole 411 to punch the terminal strip 100, the punching blade can sever the terminal connection, ensuring that the cut surface of the punched terminal is free of burrs, thereby improving the quality of the punched terminal.

[0056] In this embodiment, as Figure 3 shown in, the main body mechanism 1 includes a top plate, a bottom plate 12 and two side plates 13. The top plate, the bottom plate 12 and the two side plates 13 enclose each other to form the main body mechanism 1. In this way, while ensuring the stability of the main body mechanism 1, the structure is more simplified. Among them, the top plate, the bottom plate 12 and the two side plates 13 are connected by bolts. Specifically, the bottom plate 12 is a workbench 11. Among them, the first driving member 2, the positioning mechanism 3 and the blanking mechanism 4 are all arranged in the enclosed cavity. In this embodiment, a pulley with a locking function can also be selectively installed on the bottom plate 12 so as to move the terminal cutting equipment at any time. Regarding the pulley with a locking function, its specific structure and working principle can refer to the existing design and do not belong to the key protection content of this embodiment.
