Description

Technical Field

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

[0002] In motor production, wire trimming is a crucial step. Currently, this process often requires two steps. First, specialized equipment performs the initial trimming. However, due to the limitations of this equipment and subsequent processing requirements, this initial trimming cannot directly cut the wires to the specified length, requiring a certain amount of wire to be reserved. Subsequently, manual re-trimming is required to achieve the required length. This secondary trimming process results in a significant amount of enameled wire being scrapped. Each secondary trimming step results in the previously reserved portion becoming waste. This not only wastes raw materials, but also dramatically increases the amount of scrapped wire as production scale expands, directly increasing production costs and compressing profit margins. This problem is particularly prominent for large-scale motor manufacturers, who urgently need a new wire trimming method or device that can trim motor wires to the specified length in one go, effectively avoiding the problem of wire scrap caused by secondary trimming and improving production efficiency and resource utilization. Utility Model Content

[0003] The purpose of the utility model 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.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

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

[0032] It should be further understood that the term “and / or” used in the present specification 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 utility model discloses a lead-out wire trimming device, including a fixed seat 1, a driving mechanism 2 and a wire trimming mechanism 3; the fixed seat 1 is used to connect the driving mechanism 2 and the wire trimming mechanism 3, the driving mechanism 2 is used to drive the lead-out wire 6 to move to the wire trimming mechanism 3, and the wire trimming mechanism 3 is used to clamp and cut the lead-out wire 6; the wire trimming mechanism 3 includes a double scissors seat 31, a first cutter 32 and a second cutter 33, and 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 primarily composed of three parts: a fixed base 1, a drive mechanism 2, and a trimming mechanism 3. The fixed base 1 plays a key role in connection, integrating the drive mechanism 2 and the trimming mechanism 3 to form a stable overall structure, providing a stable working platform for the entire trimming process. The drive mechanism 2 is responsible for driving the lead wire 6 toward the trimming mechanism 3, allowing the trimming mechanism 3 to successfully cut the lead wire 6. The drive mechanism 2 and the trimming mechanism 3 are respectively disposed at opposite ends of the fixed base 1. It will be appreciated 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 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, meeting the specific length requirements 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 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 base 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 base 1 gradually narrows from bottom to top to form a second cutting edge 331 .

[0037] Specifically, the first and second cutting edges 321, 331 gradually narrow from the mounting base 1 toward the lead wire 6. This allows the thicker portions of the first and second cutters 32, 33 to disperse the pressure generated during the moment of cutting when the lead wire 6 is pulled to the cutting position, preventing damage to the first and second cutting edges 321, 331 due to excessive force. This gradually narrowing design allows the first cutting edge 321 to more precisely contact the lead wire 6. The narrower first and second cutting edges 321, 331 facilitate closer contact with the lead wire 6 during cutting, allowing for precise and clean severing of the lead wire 6, preventing problems such as the lead wire 6 being cut crooked, flattened, or disconnected, thereby ensuring quality cutting.

[0038] At the same time, the first and second blades 321, 331 are positioned relative to each other, allowing them to apply shearing forces to the lead wire 6 from both the upper and lower directions. The distance between the first and second blades 321, 331 is equal to the length of the lead wire 6 to be cut. When the lead wire 6 is delivered to the cutting position by the drive mechanism 2, the first blade 321 acts from above, while the second blade 331 acts from below. This allows the lead wire 6 to be quickly and effectively cut under the forces acting in two opposite directions, leaving a fixed length of waste material.

[0039] Understandably, traditional wire trimming requires a two-step process to achieve the required length. First, the wire is trimmed by the machine. The wire hook extends, hooks the lead wire 6, and pulls it back, causing it to strike the scissors, cutting the wire. This requires pre-requisites for the motor, with three lead wires of 157mm, 157mm, and 163mm lengths. Finally, the wire is manually trimmed to the required lengths of 127mm, 92mm, and 133mm. This process results in a total of 125mm of lead wire 6 being wasted. Furthermore, manual labor can increase costs and lead to inconsistent cutting quality.

[0040] In this embodiment, the distance between the first cutting edge 321 and the second cutting edge 331 is designed to be 10 mm. This means that after the first and second cutting edges 32 and 33 of this embodiment cut the lead wires 6 from the drive mechanism 2, only 10 mm of waste material remains, significantly reducing the length of the waste material. Furthermore, the use of a machine to trim the wires provides a certain degree of control over the quality and stability of the trimming process.

[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 cutting edge 321 and the fixed base 1 is greater than the horizontal distance between the second cutting edge 331 and the fixed base 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 the wires in sequence disperses the peak of the impact force. The lead wire 6 first contacts the first cutter 32 and is cut by the first cutting edge 321. The impact force is buffered by the first cutter 32. When the second cutting edge 331 cuts, the remaining impact force is also relatively small, thereby reducing the instantaneous impact on the fixed base 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 sequential trimming method allows for more precise control of the trimming process of the lead wire 6. Based on the characteristics of the lead wire 6, such as hardness and diameter, the horizontal distance difference between the first and second cutting edges 321, 331 and the fixing base 1 is adjusted, that is, the horizontal offset distance difference between the first and second cutting edges 321, 331 is adjusted to optimize the trimming sequence and time interval. This allows the trimming mechanism to more flexibly adapt to different types of lead wires 6, thereby improving the control accuracy of the trimmed length and quality of the lead wire 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 parallel double-edged knives 341; 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 the role of transmitting force and maintaining the integrity of the structure, so that the knife holder 34 can work in conjunction with the double scissor holder 31. Two sets of double-edged knives 341 arranged in parallel extend outward from the top and bottom of the other end of the knife holder 34 in a direction away from the fixed seat 1. They are in the same plane and parallel to each other, effectively fixing the lead wire 6 from 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 edges can be used to more accurately pierce the lead wire 6 and press the lead wire 6 to achieve fixation. Compared with the single-edged structure, the double edges can provide a more stable clamping force and can maintain better control over the lead wire 6 even when there is external force.

[0046] The knife holder 34 and its extended double-edged knife 341 are both positioned between the first cutter 32 and the second cutter 33. After the lead wire 6 is delivered to the wire trimming mechanism 3, the drive mechanism 2 pulls the lead wire 6 toward the wire trimming mechanism 3 while maintaining a certain tension, placing the lead wire 6 in a tensioned state. The lead wire 6 is brought to the double-edged knife 341, where the blade of the double-edged knife 341 pierces the outer insulation of the lead wire 6. After piercing, the pulling force of the drive mechanism 2 and the pressing force of the double-edged knife 341 are perpendicular to each other, forming a stable clamping force system that locally secures the lead wire 6 and prevents any movement of the lead wire 6 during the trimming 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 toward the wire trimming mechanism 3 (i.e., horizontally displaces toward the fixed base 1). 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 moving toward the wire trimming mechanism 3. When the lead wire 6 contacts the double-edged blade 341, the double-edged blade 341 pierces the outer insulation of the lead wire 6. At this time, the first blade 321 cuts the lead wire 6. The drive mechanism 2 continues to drive the lead wire 6 toward the fixed base 1 so that the double-edged blade 341 presses against the lead wire 6, thereby accurately fixing the lead wire 6 and preventing it from shifting or shaking during the subsequent wire trimming process. The drive mechanism 2 continues to move horizontally toward the fixed base 1 until the lead wire 6 contacts the second cutter 33 and is cut by 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, there is no need for manual secondary cutting later, which reduces the waste of related labor costs.

[0049] It can be understood that when 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 wire 6 , and the driving component 21 is used to drive the material pulling hook 22 to move closer to or 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 transportation 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 its 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 the 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 understood that the drive assembly 21 achieves this function through a power transmission mechanism, which can utilize the telescopic movement of a cylinder, a lead screw driven by a motor, or other similar transmission methods to convert power into linear motion of the material pulling hook 22. When the lead wire 6 needs to be sent to the wire trimming mechanism 3 for cutting, the drive assembly 21 drives the material pulling hook 22 to move with the lead wire 6 toward the wire trimming mechanism 3. After completing a wire trimming operation or other related operations, the material pulling hook 22 is driven away from the wire trimming mechanism 3 to prepare for the next wire trimming 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 pulling hook 22 .

[0054] Specifically, in this embodiment, the drive assembly 21 is preferably composed of a linear cylinder 211 and a piston rod 212. The linear cylinder 211 serves as a power source and can generate a driving force in a linear direction to provide power support for the entire drive mechanism 2. The piston rod 212 is used to transmit the power generated by the linear cylinder 211. 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, thereby effectively transmitting the power generated by the linear cylinder 211 to the material pulling hook 22, so that the material pulling hook 22 can move linearly under the drive of the power, thereby approaching or moving away from the wire cutting mechanism 3 to complete the related operations such as the transportation and positioning of the lead-out wire 6.

[0055] In one embodiment, the upper edge of the pulling hook 22 and the lower surface of the first cutter 32 are located at the same horizontal plane, and the lower edge of the pulling hook 22 and the upper surface of the second cutter 33 are located at 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 trimming operation, when the lead wire 6 is fixed by the material pulling hook 22 and as the material pulling hook 22 moves closer to the wire trimming mechanism 3, 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 fits tightly 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 blade 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 or second cutter 32, 33 is performing the cutting operation, the lead wire 6 is precisely cut at the predetermined location, thereby improving the precision of the motor lead wire cutting and meeting the stringent requirements for lead wire length and cutting quality in motor production. Furthermore, the pull hook 22 can move horizontally between the first and second cutters 32, 33, thereby closely fitting with the double-edged clamping knife 341, puncturing and securing the lead wire 6, thereby enabling the second cutter 33 to cut the lead wire 6 a second time.

[0058] In one embodiment, a pull pin 221 is provided on the side of the pulling hook 22 close to the first cutter 32. The pull pin 221 moves away from or passes through 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 puller pin 221 is positioned on the side of the material hook 22 near the first cutter 32. As the material hook 22 approaches the thread trimming mechanism 3, the puller pin 221 moves along with the material hook 22 toward the thread trimming mechanism 3. When the material hook 22 moves away from the thread trimming mechanism 3, the puller pin 221 follows the material hook 22 in its movement away from the thread trimming mechanism 3. It will be appreciated that when the material hook 22 moves to the cutting position, the puller pin 221 penetrates the thread trimming mechanism 3, specifically, between the first cutter 32 and the second cutter 33 of the thread trimming mechanism 3. After the lead wire 6 has been cut, the material hook 22 moves away from the thread trimming mechanism 3, and the puller pin 221 moves with it, removing the remaining lead wire 6 from the thread trimming mechanism 3, preparing for the next cleaning or other related operations.

[0060] Furthermore, in this embodiment, the puller pin 221 is positioned between the two sets of double-edged blades 341. After the shearing operation is completed, any remaining waste material may remain stuck between the double-edged blades 341 and cannot be automatically removed. The puller hook 22 drives the puller pin 221 to move between the two sets of double-edged blades 341 away from the wire trimming mechanism 3, thereby removing and clearing the waste material of the lead wire 6 stuck between the double-edged blades 341.

[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 drive mechanism 2 is responsible for moving the lead wire 6 during the entire wire trimming process, including conveying the lead wire 6 to the wire trimming mechanism 3 and performing corresponding position adjustments after the wire trimming is completed. During this process, the lead wire 6 may leave some residue inside the drive mechanism 2. The air blowing component 4 has the function of generating an airflow and directing it in a specific direction. When it is necessary to clean the lead wire 6 remaining in the drive mechanism 2, the air blowing component 4 will start and generate a strong airflow, which will be ejected in the direction of the drive mechanism 2, thereby blowing the remaining lead wire 6 away from the internal components of the drive mechanism 2, so that it no longer adheres to the drive 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 drive mechanism 2, thereby achieving airflow to clean the drive mechanism 2. It can be understood that in this embodiment, the output end of the air blowing pipe 43 is directly opposite the groove position of the material pulling hook 22, thereby clearing 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 the waste blown out from the inner side of the pulling hook 22 by the blowing pipe 43 for subsequent unified processing.

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

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

[0067] Step 2: The linear cylinder 211 works, causing the pulling hook 22 to start moving 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 blade 321 of the first cutter 32, performing preliminary positioning of the first cutting position of the lead wire 6.

[0068] Step 3: The linear cylinder 211 continues to drive the pulling hook 22 to move toward 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 off 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 pulling hook 22 to move to the initial state in the direction away from the wire cutting mechanism 3. At this time, the 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 pulling hook 22; at this point, the wire cutting device completes one cutting operation.
