Description

Technical Field

[0001] The present invention relates to the technical field of insulation gate cutting, and in particular to a metal wire insulation gate cutting device. Background Art

[0002] With the rapid development of the electronics industry, metal wires, as a crucial connection medium between electronic components, face significant challenges in processing quality and efficiency, directly impacting overall product performance and manufacturing costs. Traditional methods for cutting metal wire insulation barriers rely heavily on manual labor or simple mechanical equipment. These methods suffer from uneven insulation barrier cutting, low efficiency, and damage to the metal core, making them difficult to meet the demands of automated production.

[0003] Especially in the manufacturing of sophisticated electronic products, the insulation layer on the surface of metal wires must be stripped accurately and efficiently, while ensuring the integrity of the metal core. This requires insulation barrier cutting equipment to possess a high level of automation, precise cutting capabilities, and excellent waste disposal capabilities. However, existing metal wire insulation barrier cutting equipment often struggles to meet these requirements simultaneously, resulting in low production efficiency and inconsistent product quality.

[0004] Therefore, developing a metal wire insulation grid cutting device that can automatically, accurately and efficiently strip the insulation layer on the surface of the metal wire and simultaneously achieve orderly discharge of waste has become a technical problem that needs to be urgently solved in the electronics industry. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a metal wire insulation grid cutting device, which is capable of separating the surface insulation layer of the metal wire and the metal core wire.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a metal wire insulated grid cutting device, including a box body, a channel for the movement of the metal wire is provided inside the box body, a feed hole and a discharge hole are respectively provided at both ends of the box body, and waste ports are provided on both sides of the box body.

[0007] The interior of the box is provided with a pushing assembly, a cutting assembly and a separating assembly in sequence along the conveying direction of the channel; The pushing assembly includes a plurality of pushing groups, each pushing group includes two pushing rollers, and the two pushing rollers are respectively arranged on the upper and lower sides of the channel; The cutting assembly includes two cutting wheels symmetrically arranged along the center of the channel, and when the metal wire passes through the channel, the two cutting wheels can form cutting slots on the surface of the metal wire; There are two groups of separation components, which are respectively arranged on both sides of this plane. Each group of separation components includes a first clamping wheel and a second clamping wheel that can rotate synchronously and in opposite directions. The first clamping wheel and the second clamping wheel can push the insulating layer on the surface of the metal wire to move during the rotation process.

[0008] Preferably, an annular groove is provided on the outer annular surface of the first clamping wheel, and an annular protrusion is provided on the outer annular surface of the second clamping wheel, and the gap between the annular groove and the annular protrusion is adapted to the insulating layer on the surface of the metal wire.

[0009] Preferably, the first clamping wheel is an annular body, and a plurality of ventilation holes are provided inside the annular groove. The first clamping wheel is rotatably sleeved on the inner column, and the inner column is fixed on the frame. An air inlet groove and an air outlet groove are provided inside the inner column. The air inlet groove faces the channel for the movement of the metal wire, and the air outlet groove is away from the channel for the movement of the metal wire. When the first clamping wheel rotates, the ventilation hole is connected with the air inlet groove, and the gas passes through the ventilation hole from the outside into the inside of the air inlet groove, generating suction on the insulating layer on the surface of the metal wire outside the ventilation hole. When the ventilation hole is connected with the air outlet groove, the gas flows outward from the air outlet groove through the ventilation hole, and generates thrust on the insulating layer on the surface of the metal wire.

[0010] Preferably, the air inlet slots on both sides are connected to an air duct of the air blowing device through a first connecting pipe, and the two air outlet slots are connected to another air duct of the air blowing device through a second connecting pipe.

[0012] Preferably, a cutting edge is provided on the periphery of the cutting wheel, and the cutting edge is a convex circle with a variable diameter.

[0013] Preferably, the two cutting wheels are respectively mounted on the frame via couplings, linkage gears are fixed on both couplings, the two linkage gears are meshed with each other, and a motor for driving any one of the couplings to rotate is fixed in the frame.

[0014] Preferably, a guide wheel is rotatably installed between the cutting wheel and the inner column, and the number of the guide wheels is two, which are respectively arranged on both sides of the cutting wheel.

[0015] Preferably, the outer annular surfaces of the pushing roller and the guide wheel are both arc surfaces adapted to the metal wire.

[0016] Preferably, a guide cylinder is provided between the pushing group and the cutting wheel along the conveying direction of the channel, the guide cylinder is fixed in the frame, the guide cylinder is sleeved outside the channel, and the internal through hole of the guide cylinder is adapted to the metal wire.

[0017] The beneficial effects of the present invention are: This metal wire insulation barrier cutting device features a pair of relatively rotatable cutting wheels. Positioned on the upper and lower sides of the pipeline being processed, these wheels create a uniform gap across the pipeline. The cutting blades on the cutting wheels feature adjustable diameters, allowing the operator to flexibly adjust the distance between the cutting blades and the pipeline to meet specific needs. This effectively avoids overcutting the metal core wire or undercutting, ensuring precise insulation barrier cutting.

[0018] The device also incorporates a ventilation system inside the first clamping wheel, consisting of ventilation holes. These holes not only generate suction, trapping the insulation layer stripped from the wire surface during cutting into a specially designed annular groove, ensuring smooth movement during subsequent processing, but also, when needed, switch to a blowing mode, gently pushing the stripped insulation layer from the annular groove and guiding it through the waste outlet for orderly discharge, simplifying post-insulation barrier cleaning.

DETAILED DESCRIPTION

[0026] The present invention is described below with specific examples, but is not intended to be limiting of the invention.

[0027] Example 1 like Figure 1-Figure 2 As shown, in this embodiment, a metal wire insulation gate cutting device is provided, including a box body, the interior of which is provided with a channel for the movement of the metal wire. The cross-section of the channel is designed to be circular, and its size precisely matches the outer diameter of the metal wire, thereby ensuring that the metal wire can pass through the channel smoothly and unimpeded. A feed hole and a discharge hole are respectively provided at both ends of the box body. The metal wire first enters the interior of the channel through the feed hole. Once the metal wire passes through the channel, it will be automatically insulation gate cut by the insulation gate cutting device inside the box body. After the insulation gate cutting process is completed, the processed metal wire will be smoothly discharged from the discharge hole, and waste ports are provided on both sides of the box body. After the metal wire is processed by the insulation gate cutting, the outer surface insulation layer of the metal wire will be effectively stripped off, revealing the metal core wire inside. The waste of the stripped metal wire surface insulation layer will be smoothly discharged through the waste port.

[0028] The interior of the box is equipped with a pushing component, a cutting component and a separation component in sequence along the transmission direction of the channel. The pushing component is set near the inlet of the channel. This component is not only responsible for pushing the metal wire to move smoothly in the channel when it enters, but also has the function of sorting the metal wire to ensure that the metal wire remains in a straight state before entering the subsequent process. Next, the metal wire will encounter the cutting device, which is used to accurately cut a gap in the metal wire surface insulation layer on the outer surface of the metal wire, laying the foundation for the subsequent separation of the metal wire surface insulation layer and the metal layer. Afterwards, the separation component takes over the task. It effectively separates the metal wire surface insulation layer from the internal metal layer and discharges them through different outlets respectively, realizing an orderly processing flow.

[0029] The push assembly comprises multiple push groups, each of which includes two push rollers 2, positioned on the upper and lower sides of the channel. The symmetrical placement of the push rollers 2 significantly reduces the risk of wire squeezing caused by gaps between the two push rollers 2. Furthermore, by configuring multiple push rollers 2, the wire can be more effectively straightened, ensuring it maintains an ideal straight line before entering subsequent processing steps.

[0030] The cutting assembly includes two cutting wheels 4 arranged symmetrically along the center of the channel. When the metal wire passes through the channel, the two cutting wheels 4 can form cutting seams on the surface of the metal wire. In this embodiment, the positions of the cutting wheels 4 are distributed up and down, so that the cutting seams are set on the upper and lower sides of the metal wire. This layout allows the insulating layer on the surface of the metal wire to be cut subsequently to be discharged from the waste ports on both sides of the frame 1.

[0031] There are two groups of separation components, which are respectively arranged on both sides of this plane. Each group of separation components includes a first clamping wheel 5 and a second clamping wheel 6 that can rotate synchronously and in opposite directions. The first clamping wheel 5 and the second clamping wheel 6 are both arranged horizontally. This arrangement makes it easier for the stripped metal wire to be discharged from the waste outlet. The first clamping wheel 5 and the second clamping wheel 6 can push the surface insulation layer of the metal wire to move during the rotation process. In the process of the metal wire surface insulation layer being pushed and moved, the first clamping wheel 5 and the second clamping wheel 6 not only cooperate to provide a forward driving force, but also synchronously apply a clamping force. The combined effect of this clamping force and the driving force causes the two sides of the metal wire surface insulation layer to be pulled outward, thereby effectively promoting the separation process between the metal wire surface insulation layer and the central metal core wire, making the separation operation smoother.

[0032] Example 2 like Figures 1-4 As shown, based on the first embodiment, this embodiment provides a device for guiding the cut surface insulation layer of the metal wire to be discharged from the waste outlet, which is specifically as follows: An annular groove is provided on the outer ring surface of the first clamping wheel 5, and an annular protrusion is provided on the outer ring surface of the second clamping wheel 6. The gap between the annular groove and the annular protrusion is adapted to the insulating layer on the surface of the metal wire, and the annular groove and the annular protrusion on the insulating layer on the surface of the metal wire match each other. This shape adaptability ensures that the arc surface above the metal wire can fit more tightly and firmly inside the annular groove, effectively preventing the insulating layer on the surface of the metal wire from accidentally falling off from the annular groove.

[0033] The first clamping wheel 5 is an annular body, and a plurality of ventilation holes are provided inside the annular groove. The first clamping wheel 5 is rotatably sleeved on the inner column 7, and the inner column 7 is fixed on the frame 1. An air inlet groove 8 and an air outlet groove 9 are provided inside the inner column 7. During the rotation of the annular body, it will periodically communicate with the air inlet groove 8 and the air outlet groove 9. At the same time, at different stages of rotation, it will also come into contact with other areas on the inner column 7. The air inlet groove 8 faces the channel for the movement of the metal wire, and the air outlet groove 9 is away from the channel for the movement of the metal wire. When the first clamping wheel 5 rotates, When the vent is connected to the air inlet slot 8, gas passes through the vent from the outside and enters the inside of the air inlet slot 8, generating suction on the metal wire surface insulation layer outside the vent. When the vent is connected to the air outlet slot 9, gas flows outward from the air outlet slot 9 through the vent, generating thrust on the metal wire surface insulation layer. When the vent is connected to the air inlet slot 8, the suction effect generated will tightly adsorb the cut metal wire surface insulation layer onto the annular groove. This suction forces the metal wire surface insulation layer to adhere closely to the annular groove and move along with the corresponding first clamping wheel 5. When the vent is in turn connected to the air outlet slot 9, the thrust generated acts on the metal wire surface insulation layer, causing it to break away from the adsorption of the annular groove, approach the second clamping wheel 6, and ultimately be smoothly discharged through the waste outlet.

[0034] The air inlet slots 8 on either side are connected to one air duct of a blasting device 13 via a first connecting pipe 11, while the two air outlet slots 9 are connected to another air duct of the blasting device 13 via a second connecting pipe 12. Under the action of the blasting device 13, the gas flows smoothly along a predetermined path. This process begins at the air inlet slots 8, is guided through the air inlet duct, then passes through the air outlet duct, and finally is discharged from the air outlet slots 9. This flow mechanism effectively achieves the desired effect of gas adsorption and directional removal.

[0035] Example 3 like Figures 1-6 As shown, based on the first and second embodiments, this embodiment provides a stabilizing device for a metal wire, specifically as follows: A gear sleeve 10 is fixed to the bottom of the first clamping wheel 5, and the gear sleeve 10 extends to the inside of the frame 1. A motor for driving the gear sleeve 10 to rotate is installed inside the frame 1. A gear is fixed on the output shaft of the motor, and the gear is engaged with the gear sleeve 10, thereby driving the gear sleeve 10 to rotate, and the gear sleeve 10 drives the first clamping wheel 5 to rotate.

[0036] The cutting wheel 4 is equipped with a cutting blade on its periphery. This blade is a convex, variable-diameter circle, capable of precisely cutting through the insulation layer on the surface of the metal wire. Its unique variable-diameter design allows the user to flexibly adjust the distance between the cutting blade and the metal core wire according to actual needs. This feature is particularly important when dealing with overcutting or incomplete cutting during the cutting process, as it allows the operator to make instant fine adjustments to the cutting blade to ensure accurate and efficient cutting.

[0037] The two cutting wheels 4 are respectively mounted on the frame 1 through a coupling, and a linkage gear 15 is fixed on each of the two couplings. The two linkage gears 15 are meshed with each other. A motor for driving any one of the couplings to rotate is fixed inside the frame 1. When the two meshing linkage gears 15 are combined together, if one of the gears is driven to rotate by the motor, the two gears will work together, each driving the shafts to which they are connected to rotate simultaneously at the same speed but in opposite directions.

[0038] A guide wheel 14 is rotatably installed between the cutting wheel 4 and the inner column 7. There are two guide wheels 14, which are respectively arranged on both sides of the cutting wheel 4. A motor for driving the guide wheels 14 to rotate is installed inside the frame 1. The two guide wheels 14 can apply axial tension to the insulating layer on the surface of the cut metal wire, making cutting easier to complete.

[0039] The outer ring surfaces of the pushing roller 2 and the guide wheel 14 are both arc surfaces adapted to the metal wire, and the arc surfaces are more likely to contact the metal wire and generate a pressing force.

[0040] A guide cylinder 3 is provided between the pushing group and the cutting wheel 4 along the transmission direction of the channel. The guide cylinder 3 is fixed in the frame 1 and is sleeved outside the channel. The internal through hole of the guide cylinder 3 is adapted to the metal wire. The guide cylinder 3 guides the metal wire to avoid deviation of the path of the relationship.

[0041] Working principle: When the metal wire is introduced into the frame 1, it is first fed in through the feed port and then encounters a series of carefully designed push rollers 2. These push rollers 2 not only tightly press the metal wire but also work together to push it forward, ensuring that the metal wire is arranged into a relatively straight path during its travel.

[0042] After initial preparation by the push roller 2, the wire continues to the guide cylinder 3. Next, two cutting wheels 4, positioned above and below, precisely cut the insulating layer on the wire surface, leaving two corresponding slits on the wire surface, marking the completion of the cutting process.

[0043] The cut wire is then guided by guide wheels 14 to the first clamping wheel 5. Ventilation holes on the first clamping wheel 5 play a crucial role at this point, applying suction to the insulation layer on the freshly cut wire surface, forcing it to move against the surface of the first clamping wheel 5. When the insulation is drawn into the narrow gap between the first and second clamping wheels 5, the two sets of clamping wheels not only apply clamping force and pressure to the wire insulation, but also enable further processing through their specialized design.

[0044] As the wire's surface insulation passes between the first and second clamping wheels 5, 6, the ventilation holes on the first clamping wheel 5 change their function from suction to blowing. This airflow effectively removes the wire's surface insulation from the outer surface of the first clamping wheel 5 and guides it toward the waste outlet, effectively separating the wire's surface insulation from the core wire.

[0045] At the same time, the two second clamping wheels 6 at the rear end of the system are responsible for pushing the metal core wire left after cutting to continue moving forward, and finally it is smoothly discharged through the outlet of the channel, completing the entire processing process.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
