Description

Technical Field

[0001] The invention relates to the field of coil equipment manufacturing, and more specifically to a lead-out wire trimming device. Background Art

[0002] In the field of motor production, the cutting of motor lead wires is an important link. At present, the cutting of motor lead wires often needs to be carried out in two times. First, the first cutting is carried out by specific equipment. Due to the limitations of the equipment itself and the needs of subsequent processing, this cutting cannot directly cut the lead wire to the final specified length, and a certain length of lead wire needs to be reserved. Subsequently, manual secondary cutting is required to reach the specified length. This secondary cutting method leads to the scrapping of a large number of lead wires. Each secondary cutting process will make the previously reserved part of the lead wire become waste. This not only means a waste of raw materials, but also with the expansion of production scale, the number of lead wires scrapped will increase sharply, which directly increases production costs and compresses the profit margins of enterprises. For enterprises that produce motors on a large scale, this problem is particularly prominent, and there is an urgent need for a new cutting method or device that can cut the motor lead wire to the specified length at one time, thereby effectively avoiding the problem of lead wire scrapping caused by secondary cutting, and improving production efficiency and resource utilization. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a lead-out wire trimming device, which aims to solve the problem of lead-out wire waste caused by the need for manual secondary trimming of the existing lead-out wire trimming device.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A lead-out wire trimming device comprises a fixing seat, a driving mechanism and a trimming mechanism; the fixing seat is used to connect the driving mechanism and the trimming mechanism, the driving mechanism is used to drive the lead-out wire to move to the trimming mechanism, and the trimming mechanism is used to clamp and cut the lead-out wire;

[0006] The thread cutting mechanism comprises a double scissors seat, a first cutter and a second cutter, wherein the first cutter and the second cutter are arranged on the double scissors seat.

[0007] In one embodiment, the end of the first cutter away from the fixing seat gradually narrows from top to bottom to form a first cutting edge, and the end of the second cutter away from the fixing seat gradually narrows from bottom to top to form a second cutting edge.

[0008] In one embodiment, a horizontal distance between the first blade and the fixing seat is greater than a horizontal distance between the second blade and the fixing seat.

[0009] In one embodiment, the wire cutting mechanism also includes a knife holder, one end of which is fixedly connected to the double scissors seat by a connecting rod, and the top and bottom of the other end of the knife holder extend outward from the knife holder away from the fixed seat to form two sets of double-edged knives arranged in parallel; the knife holder and the double-edged knife are both arranged between the first cutter and the second cutter.

[0010] In one embodiment, the horizontal distance from the blade of the two sets of double-edged knives to the fixed seat is greater than the horizontal distance from the second blade to the fixed seat, and the horizontal distance from the blade of the two sets of double-edged knives to the fixed seat is less than the horizontal distance from the first blade to the fixed seat.

[0011] In one embodiment, the driving mechanism includes a driving component and a material pulling hook, the material pulling hook is used to fix the lead-out wire, and the driving component is used to drive the material pulling hook to approach or move away from the wire cutting mechanism.

[0012] In one embodiment, the driving assembly includes a linear cylinder and a piston rod, one end of the piston rod is connected to the output end of the linear cylinder, and the other end of the piston rod passes through the fixing seat and is connected to the material pulling hook.

[0013] In one embodiment, the upper edge of the material pulling hook and the lower surface of the first cutter are located in the same horizontal plane, and the lower edge of the material pulling hook and the upper surface of the second cutter are located in the same horizontal plane.

[0014] In one embodiment, a pull pin is provided on one side of the pulling hook close to the first cutter, and the pull pin moves away from or penetrates the wire cutting mechanism as the pulling hook moves, so as to remove the lead wire remaining on the wire cutting mechanism.

[0015] In one embodiment, a blowing assembly is further provided on the double scissor seat, and the blowing assembly is used to remove the lead wires remaining in the driving mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the coordination of the pull hook, upper cutter, lower cutter and clamping knife, the lead wire is pulled to the set position and then clamped and fixed to achieve precise cutting. The lead wire can be cut to the required length at one time, leaving only a fixed length of waste, thus avoiding the waste of a large amount of lead wire caused by multiple wire cutting and reducing production costs; at the same time, it avoids the increase of manual operation links due to multiple wire cutting or cleaning of waste, thereby saving labor costs. (2) The air blowing component can blow away the waste remaining on the inside of the pull hook after shearing, which is convenient for keeping the pull hook clean, avoiding waste accumulation that affects subsequent wire cutting operations, and ensuring the smooth progress of the wire cutting process.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0032] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] See also Figures 1 to 8 As shown, the present invention discloses a lead-out wire trimming device, comprising a fixed seat 1, a driving mechanism 2 and a trimming mechanism 3; the fixed seat 1 is used to connect the driving mechanism 2 and the trimming mechanism 3, the driving mechanism 2 is used to drive the lead-out wire 6 to move to the trimming mechanism 3, the trimming mechanism 3 is used to clamp and cut the lead-out wire 6; the trimming mechanism 3 comprises a double scissors seat 31, a first cutter 32 and a second cutter 33, the first cutter 32 and the second cutter 33 are arranged on the double scissors seat 31.

[0034] Specifically, the lead wire trimming device in this embodiment is mainly composed of three parts: a fixed seat 1, a driving mechanism 2 and a trimming mechanism 3. The fixed seat 1 plays a key role in connection. It integrates the driving mechanism 2 and the trimming mechanism 3 to form a stable overall structure, providing a stable working platform for the entire trimming process. The driving mechanism 2 is responsible for driving the lead wire 6 to move toward the trimming mechanism 3, so that the trimming mechanism 3 can smoothly complete the cutting work of the lead wire 6. The driving mechanism 2 and the trimming mechanism 3 are respectively arranged at both ends of the fixed seat 1. It can be understood that the lead wire 6 in this embodiment is an enameled wire.

[0035] The wire cutting mechanism 3 realizes effective clamping and cutting of the lead wire 6. The double scissor seat 31 provides a stable installation platform for the first cutter 32 and the second cutter 33. The first cutter 32 and the second cutter 33 are located at the upper and lower ends of the double scissor seat 31 and are arranged opposite to each other, thereby realizing the secondary cutting of the lead wire 6. Compared with the traditional method of multiple adjustments or inaccurate wire cutting, the secondary cutting of the wire cutting mechanism 3 can more accurately cut the lead wire 6 to the required length to meet the requirements of the specific length of the motor lead wire. When the lead wire 6 is sent to the wire cutting mechanism 3 by the driving mechanism 2, the lead wire 6 is clamped, and then the first cutter 32 and the second cutter 33 cut it, avoiding problems such as continuous cutting, uneven wire cutting, or displacement of the lead wire 6 during the cutting process, thereby improving the wire cutting quality. It can be understood that the distance between the first cutter 32 and the second cutter 33 is equal to the length of the lead wire 6 that needs to be cut, thereby ensuring that the lead wire 6 is cut at a fixed length, reducing the waste of the lead wire 6, and indirectly reducing the production cost. This advantage will be more obvious especially in large-scale motor production.

[0036] In one embodiment, the end of the first cutter 32 away from the fixing seat 1 gradually narrows from top to bottom to form a first cutting edge 321 , and the end of the second cutter 33 away from the fixing seat 1 gradually narrows from bottom to top to form a second cutting edge 331 .

[0037] Specifically, the first blade 321 and the second blade 331 are designed to gradually narrow from the fixing seat 1 to the lead wire 6, so that when the lead wire 6 is pulled to the wire cutting position, the thicker parts of the first cutter 32 and the second cutter 33 help to disperse the pressure generated at the moment of wire cutting, and prevent the first blade 321 and the second blade 331 from being damaged due to excessive force. The gradually narrowing design makes the first blade 321 more accurate when contacting the lead wire 6. The narrower first blade 321 and the second blade 331 are conducive to more closely contacting the lead wire 6 when cutting the wire, and accurately and cleanly cutting the lead wire 6, avoiding the problems of the lead wire 6 being cut crooked, flattened or cut, and ensuring the quality of wire cutting.

[0038] At the same time, the first blade 321 and the second blade 331 are arranged opposite to each other so that they can apply shearing force to the lead wire 6 from both upper and lower directions. The distance between the first blade 321 and the second blade 331 is equal to the length of the lead wire 6 to be cut. When the lead wire 6 is sent to the wire cutting position by the driving mechanism 2, the first blade 321 acts on the lead wire 6 from the top and the second blade 331 acts on the lead wire 6 from the bottom, so that the lead wire 6 is quickly and effectively cut under the forces in two opposite directions, leaving a fixed length of waste.

[0039] It is understandable that the traditional wire cutting method needs to be divided into two steps to complete the wire cutting of the specified length: first, the wire is cut by the equipment. The wire hook extends out to hook the lead wire 6 and pull it back, so that the lead wire 6 hits the scissors to form a cutting effect. During use, three lead wires with lengths of 157mm, 157mm, and 163mm need to be reserved for the motor; finally, they are manually cut to the specified lengths of 127mm, 92mm, and 133mm. In other words, a total of 125mm lead wires 6 will be wasted in this process. At the same time, the use of manual labor will increase costs on the one hand, and on the other hand, the use of manual labor may lead to unstable wire cutting quality.

[0040] In this embodiment, the distance between the first blade 321 and the second blade 331 is designed to be 10 mm, that is, after the first cutter 32 and the second cutter 33 in this embodiment cut the lead wire 6 brought by the driving mechanism 2, only 10 mm of waste is left, which greatly reduces the length of the waste. At the same time, the machine is used to cut the wire, which controls the quality stability of the cutting to a certain extent.

[0041] In one embodiment, a horizontal distance between the first blade edge 321 and the fixing base 1 is greater than a horizontal distance between the second blade edge 331 and the fixing base 1 .

[0042] Specifically, the horizontal distance between the first blade 321 and the fixed seat 1 is greater than the horizontal distance between the second blade 331 and the fixed seat 1, that is, the first cutter 32 and the second cutter 33 are misaligned in the horizontal direction. When the lead wire 6 is transported to the wire cutting mechanism 3 by the driving mechanism 2, the first cutter 32 and the second cutter 33 will not contact and cut the lead wire 6 at the same time, and the impact force during wire cutting will not act on the entire wire cutting mechanism 3 at the same time. Compared with simultaneous cutting, this method of cutting wires in sequence disperses the peak value of the impact force. The lead wire 6 first contacts the first cutter 32 and is cut by the first blade 321 first. The impact force is buffered by the first cutter 32. When the second blade 331 cuts again, the remaining impact force is also relatively small, thereby reducing the instantaneous impact on the fixed seat 1, the double scissors seat 31 and other related components, extending the service life of the equipment, and reducing the risk of damage to the equipment due to excessive impact force.

[0043] At the same time, the method of cutting the wires one after another enables more precise control of the cutting process of the lead wires 6. According to the characteristics of the lead wires 6 such as hardness and diameter, by adjusting the horizontal distance difference between the first blade 321 and the second blade 331 and the fixing seat 1, that is, adjusting the horizontal offset distance difference between the first blade 321 and the second blade 331, the cutting sequence and time interval are optimized, so that the cutting mechanism can more flexibly adapt to different types of lead wires 6, and improve the control accuracy of the cutting length and quality of the lead wires 6.

[0044] In one embodiment, the thread cutting mechanism 3 also includes a knife holder 34, one end of which is fixedly connected to the double scissors seat 31 via a connecting rod 35, and the top and bottom of the other end of the knife holder 34 extend outward from the knife holder 34 in a direction away from the fixed seat 1 to form two sets of double-edged knives 341 arranged in parallel; the knife holder 34 and the double-edged knife 341 are both arranged between the first cutter 32 and the second cutter 33.

[0045] Specifically, one end of the knife holder 34 is fixedly connected to the double scissor holder 31 through a connecting rod 35. The connecting rod 35 plays a role in transmitting force and maintaining the integrity of the structure, so that the knife holder 34 can work in coordination with the double scissor holder 31. The top and bottom of the other end of the knife holder 34 extend outward in a direction away from the fixed seat 1 to form two sets of double-edged knives 341 arranged in parallel. They are in the same plane and parallel to each other, and effectively fix the lead wire 6 from both the upper and lower directions. Each set of double-edged knives 341 has a double-edged structure. When in contact with the lead wire 6, the double-edged blades can be used to more accurately pierce the lead wire 6 and press the lead wire 6 to achieve fixation. Compared with a single-edged structure, a double-edged blade can provide a more stable clamping force and can maintain better control over the lead wire 6 when there is an external force.

[0046] The knife holder 34 and the double-edged knife 341 extending therefrom are both arranged between the first cutter 32 and the second cutter 33. After the lead wire 6 is conveyed to the wire cutting mechanism 3, under the action of the driving mechanism 2, the lead wire 6 is pulled toward the wire cutting mechanism 3 and a certain tension is maintained, and the lead wire 6 is in a tensioned state. The lead wire 6 is brought to the double-edged knife 341, and the blade of the double-edged knife 341 is designed to pierce the outer insulation of the lead wire 6. After the piercing, the tension of the driving mechanism 2 and the pressing force of the double-edged knife 341 are perpendicular to each other, forming a stable clamping force system, so that the lead wire 6 is firmly fixed locally, avoiding any form of movement of the lead wire 6 during the wire cutting process.

[0047] In one embodiment, the horizontal distance from the blades of the two sets of double-edged knives 341 to the fixed seat 1 is greater than the horizontal distance from the second blade 331 to the fixed seat 1, and the horizontal distance from the blades of the two sets of double-edged knives 341 to the fixed seat 1 is less than the horizontal distance from the first blade 321 to the fixed seat 1.

[0048] Specifically, when the wire trimming process begins, the drive mechanism 2 drives the lead wire 6 to move toward the wire trimming mechanism 3 (i.e., horizontally displaced toward the fixed seat 1), and the lead wire 6 first contacts the first cutter 32. When the first blade 321 of the first cutter 32 contacts the lead wire 6, the approximate position of the lead wire 6 in the wire trimming mechanism 3 is preliminarily determined. The drive mechanism 2 drives the lead wire 6 to continue to move toward the wire trimming mechanism 3. When the lead wire 6 contacts the double-edged knife 341, the double-edged knife 341 will pierce the outer insulation of the lead wire 6. At this time, the first blade 321 cuts off the lead wire 6. The drive mechanism 2 continues to drive the lead wire 6 to move toward the fixed seat 1 so that the double-edged knife 341 presses against the lead wire 6, thereby accurately fixing the lead wire 6 to prevent it from being displaced or shaken during the subsequent wire trimming process. The drive mechanism 2 continues to horizontally displace toward the fixed seat 1 until the lead wire 6 contacts the second cutter 33 and the lead wire 6 is cut through the second blade 331. At this point, the lead wire 6 has been cut to the required length of the product at one time, leaving only the waste between the first cutting edge 321 and the second cutting edge 331, which greatly reduces the waste of the lead wire 6. At the same time, no manual secondary cutting is required later, reducing the waste of related labor costs.

[0049] It can be understood that after the lead wire 6 is cut off by the first cutting edge 321, the lead wire 6 is pressed tightly between the double-edged knife 341. When the lead wire 6 is driven to the second cutting edge 331 by the driving mechanism 2, the lead wire 6 between the double-edged knife 341 and the second cutting edge 331 is still in a tensioned state, thereby ensuring the accuracy of the cutting position of the lead wire 6 at the second cutting edge 331.

[0050] In one embodiment, the driving mechanism 2 includes a driving component 21 and a material pulling hook 22 , the material pulling hook 22 is used to fix the lead-out wire 6 , and the driving component 21 is used to drive the material pulling hook 22 to approach or move away from the wire cutting mechanism 3 .

[0051] Specifically, the drive assembly 21 and the material pulling hook 22 cooperate with each other to jointly complete the related operations such as the conveying and positioning of the lead wire 6, so that the lead wire 6 can accurately reach the wire cutting mechanism 3 for cutting. The material pulling hook 22 is in close contact with the lead wire 6 and firmly grasps it to prevent the lead wire 6 from slipping, loosening, etc. during the subsequent movement. It can be understood that the fixing method can be achieved by mechanical clamping, hooking or other methods that can provide sufficient fixing force, depending on its actual design details. In this embodiment, the material pulling hook 22 adopts a hook form to ensure that the lead wire 6 is firmly hooked during transportation and maintains a relatively stable state. The drive assembly 21 is responsible for driving the material pulling hook 22 to move, so that the material pulling hook 22 is close to or away from the wire cutting mechanism 3.

[0052] It is understandable that the driving component 21 realizes this function through a power transmission mechanism, and can utilize the telescopic movement of the cylinder, the screw transmission driven by the motor, or other similar transmission methods to convert the power into the linear movement of the material pulling hook 22. When the lead wire 6 needs to be sent to the wire cutting mechanism 3 for cutting, the driving component 21 drives the material pulling hook 22 to move with the lead wire 6 toward the wire cutting mechanism 3; and after completing a wire cutting operation or other related operations, the material pulling hook 22 is driven away from the wire cutting mechanism 3 to prepare for the next wire cutting operation or equipment adjustment.

[0053] In one embodiment, the driving assembly 21 includes a linear cylinder 211 and a piston rod 212 , one end of the piston rod 212 is connected to the output end of the linear cylinder 211 , and the other end of the piston rod 212 passes through the fixing seat 1 and is connected to the material pulling hook 22 .

[0054] Specifically, in the present embodiment, the driving assembly 21 is preferably composed of a linear cylinder 211 and a piston rod 212. The linear cylinder 211, as a power source, can generate a driving force in a linear direction, and provide power support for the entire driving mechanism 2. The piston rod 212 is used to transmit the power generated by the linear cylinder 211, and one end of the piston rod 212 is connected to the output end of the linear cylinder 211. When the piston in the linear cylinder 211 moves linearly, the power generated by it will be transmitted through the piston rod 212. The other end of the piston rod 212 passes through the fixed seat 1 and is finally connected to the material pulling hook 22, so that the power generated by the linear cylinder 211 is effectively transmitted to the material pulling hook 22, so that the material pulling hook 22 can move linearly under the drive of the power, so as to achieve approaching or moving away from the wire cutting mechanism 3, so as to complete the related operations such as conveying and positioning of the lead wire 6.

[0055] In one embodiment, the upper edge of the material pulling hook 22 and the lower surface of the first cutting knife 32 are located in the same horizontal plane, and the lower edge of the material pulling hook 22 and the upper surface of the second cutting knife 33 are located in the same horizontal plane.

[0056] Specifically, the height of the material pulling hook 22 is equal to the vertical distance between the first cutter 32 and the second cutter 33. During the wire cutting operation, when the lead wire 6 is fixed by the material pulling hook 22 and moves close to the wire cutting mechanism 3 as the material pulling hook 22 moves, the upper edge of the material pulling hook 22 is flush with the lower surface of the first cutter 32, that is, when the lead wire 6 reaches the first cutting edge 321 and is ready to be cut, the upper edge of the material pulling hook 22 is tightly matched with the first cutting edge 321, so that the lead wire 6 can be well confined in the space between the material pulling hook 22 and the first cutter 32 at the moment of being cut, avoiding unnecessary upward displacement or jumping of the lead wire 6 during the cutting process, thereby ensuring the accuracy of the wire cutting position. The lower edge of the pulling hook 22 is flush with the upper surface of the second cutter 33, that is, when the second cutter 33 cuts the other end of the lead wire 6, the second cutting edge 331 fits tightly with the lower edge of the pulling hook 22, stably restricting the lead wire 6 in the space between the pulling hook 22 and the second cutter 33, preventing the lead wire 6 from shifting or jumping downward when cut, further ensuring the accuracy of the cutting position.

[0057] Whether the first cutter 32 or the second cutter 33 performs the cutting operation, it can ensure that the lead wire 6 is accurately cut at the predetermined position, thereby improving the cutting accuracy of the motor lead wire and meeting the strict requirements of the motor production on the lead wire length and cutting quality. At the same time, the material pulling hook 22 can move horizontally between the first cutter 32 and the second cutter 33, so as to fit closely with the double-edged clamping knife 341, so as to pierce and fix the lead wire 6, so as to achieve the second cutting of the lead wire 6 by the second cutter 33.

[0058] In one embodiment, a pull pin 221 is provided on one side of the pulling hook 22 close to the first cutting knife 32 , and the pull pin 221 moves away from or penetrates the wire cutting mechanism 3 as the pulling hook 22 moves to remove the lead wire 6 remaining on the wire cutting mechanism 3 .

[0059] Specifically, the pull pin 221 is arranged on the side of the material pulling hook 22 close to the first cutter 32. When the material pulling hook 22 approaches the wire cutting mechanism 3, the pull pin 221 will move toward the wire cutting mechanism 3 together with the material pulling hook 22. When the material pulling hook 22 moves away from the wire cutting mechanism 3, the pull pin 221 moves with the material pulling hook 22 in the direction away from the wire cutting mechanism 3. It can be understood that when the material pulling hook 22 moves to the cutting position, the pull pin 221 will penetrate the wire cutting mechanism 3, that is, it will be inserted between the first cutter 32 and the second cutter 33 of the wire cutting mechanism 3. When the lead wire 6 completes the cutting action, the material pulling hook 22 moves in the direction away from the wire cutting mechanism 3, and the pull pin 221 moves accordingly and takes the remaining lead wire 6 away from the wire cutting mechanism 3, so as to prepare for the next cleaning action or other related operations.

[0060] Furthermore, in this embodiment, the material extraction pin 221 is inserted between the two sets of double-edged knives 341. After the shearing action is completed, the remaining waste may still be stuck between the double-edged knives 341 and cannot be actively disengaged. The material pulling hook 22 drives the material extraction pin 221 to move between the two sets of double-edged knives 341 in a direction away from the wire cutting mechanism 3, so that the waste of the lead wire 6 stuck between the double-edged knives 341 can be disengaged and cleaned.

[0061] In one embodiment, a blowing assembly 4 is further provided on the double scissor seat 31 , and the blowing assembly 4 is used to remove the lead wires 6 remaining in the driving mechanism 2 .

[0062] Specifically, the driving mechanism 2 is responsible for driving the lead wire 6 to move during the entire wire trimming process, including conveying the lead wire 6 to the wire trimming mechanism 3 and performing corresponding position adjustments after completing the wire trimming. During this process, the lead wire 6 may leave some residue inside the driving mechanism 2. The air blowing component 4 has the function of generating airflow and directing it in a specific direction. When it is necessary to clean the lead wire 6 remaining in the driving mechanism 2, the air blowing component 4 will start and generate a strong airflow, which will be ejected in the direction of the driving mechanism 2, thereby blowing the remaining lead wire 6 away from the internal components of the driving mechanism 2, so that it is no longer attached to the driving mechanism 2, thereby achieving the purpose of cleaning.

[0063] Furthermore, the air blowing assembly 4 includes a connecting block 41, an air connection pipe 42 and an air blowing pipe 43. The connecting block 41 is fixedly mounted on the top of the double scissor seat 31. The air connection pipe 42 and the air blowing pipe 43 are both fixedly connected to the connecting block 41. One end of the air connection pipe 42 is connected to the input end of the air blowing pipe 43, and the other end is connected to an external air compressor. The output end of the air blowing pipe 43 corresponds to the position of the driving mechanism 2, so that the air flow cleans the driving mechanism 2. It can be understood that in this embodiment, the output end of the air blowing pipe 43 is directly opposite to the groove position of the material pulling hook 22, so as to remove the waste material remaining inside the material pulling hook 22.

[0064] Furthermore, a waste box 5 is provided at the bottom of the double scissor seat 31 for collecting waste blown out from the inner side of the material pulling hook 22 by the air blowing pipe 43 for subsequent unified processing.

[0065] In summary, the specific working process of a lead-out wire trimming device provided by an embodiment of the present invention is as follows:

[0066] Step 1: The wire cutting device is in the initial state, and one end of the lead wire 6 to be cut is placed on the material pulling hook 22.

[0067] Step 2: The linear cylinder 211 works to make the pulling hook 22 start to move toward the wire cutting mechanism 3 to the first stroke. At this time, the lead wire 6 on the pulling hook 22 is in a tensioned state, and the lead wire 6 abuts against the first cutting edge 321 of the first cutter 32 to perform preliminary positioning of the first cutting position of the lead wire 6.

[0068] Step three: The linear cylinder 211 continues to drive the pulling hook 22 to move toward the direction of the wire cutting mechanism 3 to the second stroke. At this time, one end of the lead wire 6 is cut off by the first blade 321, and at the same time, the lead wire 6 is pierced and tightened by the double-edged knife 341. The pulling hook 22 and the double-edged knife 341 clamp the lead wire 6 to prevent the lead wire 6 from being displaced and causing wire cutting errors.

[0069] Step 4: The linear cylinder 211 continues to drive the pulling hook 22 to move toward the wire cutting mechanism 3 to the third stroke. At this time, the other end of the lead wire 6 is cut by the second blade 331 of the second cutter 33, and the waste of the lead wire 6 is fixed between the pulling hook 22 and the double-edged clamping knife 341.

[0070] Step 5: The linear cylinder 211 drives the material pulling hook 22 to move to the initial state in the direction away from the wire cutting mechanism 3. At this time, the material pulling pin 221 is inserted between the two sets of double-edged knifes 341, so that the waste material remaining on the double-edged knife 341 is separated and removed; at the same time, the blowing component 4 is started to remove the waste material remaining on the inner side of the material pulling hook 22; at this point, the wire cutting device completes a cutting operation.
