Description

Technical Field

[0001] The utility model relates to the technical field of processing of heating components of electronic cigarettes, and particularly relates to a wire stripping and cutting mechanism. Background Technique

[0002] An electronic cigarette realizes heating and atomization by heating e-liquid through a heating wire arranged inside it. For example, a heating mesh strip with leads welded thereon disclosed in a Chinese patent document with the publication number CN217986689U belongs to the technical field of electronic cigarettes, and includes a metal substrate. A heating mesh strip main body is formed by stamping in the middle of the metal substrate. Two leads are symmetrically welded at both ends of the heating mesh strip main body. The two leads are parallel to each other and extend out of one end of the metal substrate. And a plurality of the metal substrates are provided and are connected in sequence to form a metal strip. And two semi-circular notches are symmetrically opened on both sides of one end of the metal substrate away from the leads. And after adjacent two metal substrates are connected, the semi-circular notches are butted to form positioning holes. This heating mesh strip with leads welded thereon can use the metal substrate to improve the overall strength of the heating mesh strip main body, thereby initially ensuring the service life of the heating mesh strip main body, and cooperating with the leads to supply power to the heating mesh strip main body, thereby ensuring the stability of power supply to further ensure the service life of the heating mesh strip main body. One metal substrate can correspond to two leads (pins), or can also correspond to other quantities, such as four.

[0003] During the welding process of the heating mesh of an electronic cigarette, currently, it is generally manual welding or automatic single-strip welding; for manual welding, the pins of the heating mesh are cut manually, the pins are placed on a welding mold through manual plate setting, and then a pre-etched heating mesh is covered on the top layer, and then the mold is clamped on the platform of a laser welding device for welding. However, the heating mesh welded manually has large and insecure welding points, and it is easy to appear phenomena such as virtual welding and false welding. At the same time, the production capacity is low, and a large amount of labor force is wasted.

[0004] Then, automated pin welding equipment appeared. For example, a Chinese patent document with the publication number CN215966882U discloses a device for bidirectionally welding pin wires of a heating mesh strip, including a laser welding device and two heating mesh strip stepping mechanisms. The two heating mesh strip stepping mechanisms both include a conveying platform. The feeding directions of the two conveying platforms are opposite. A welding station is arranged on the conveying platform. A wire stripping mechanism and a wire feeding mechanism are respectively arranged on both sides of the two conveying platforms. The wire feeding mechanism is used to receive the pin wires stripped by the wire stripping mechanism and convey them to the welding station; an upper pressing mechanism and a lower pressing mechanism for fitting the heating mesh strip and the pin wires are respectively arranged on the upper and lower sides of the welding station; the laser welding device is used to weld the heating mesh strip and the pin wires at the welding station; realizing the automatic production of welding pin wires of two heating mesh strips by the same laser welding machine, and improving the utilization rate of the laser welding device.

[0005] Another example is a Chinese patent document with publication number CN210413020U, which discloses a heating plate spot welding device, including a feeding and cutting device for conveying the lead to the heating plate and cutting the lead, and a spot welding device for spot welding the lead to the heating plate, both of which are arranged on a base. It uses an automated device to replace manual welding points to achieve the welding of the electronic cigarette heating plate pins, which greatly improves efficiency and ensures quality.

[0006] The incoming material of the pin wire is a coil, and the pin wire includes a metal core and an insulating skin wrapped outside the metal core. Before welding the metal substrate and the pin, the pin is cut into a preset length and the insulating skin at both ends of the pin is removed. The prior art uses a finger cylinder to drive the stripping blade to achieve the stripping and cutting of the pin. Since the cylinder has only one stroke of opening and closing, one cylinder can only achieve stripping or cutting, and it is necessary to set up the stripping and cutting mechanisms separately, which is complex in structure and poor in flexibility. Summary of the invention

[0007] In view of the above technical problems existing in the prior art, the utility model provides a wire stripping and cutting mechanism.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] The threads of the upper connecting seat and the lower connecting seat are opposite to each other, so that the stripping drive motor drives the screw to rotate and can drive the upper blade and the lower blade to approach to the stripping state and the cutting state. In the stripping state, the teeth of the upper blade and the teeth of the lower blade bite into the insulation of the wire and leave a wire hole for the metal core of the wire to pass through; in the cutting state, the upper blade and the lower blade cooperate with each other to cut the wire.

[0011] Specifically, it also includes a stripping transverse movement driving member for driving the stripping base to move transversely back and forth.

[0012] Specifically, the stripping base is U-shaped as a whole, and includes an upper base plate, a lower base plate, and an intermediate vertical plate standing between the upper base plate and the lower base plate. The two ends of the screw rod are installed on the upper base plate and the lower base plate via bearings. The intermediate vertical plate is provided with a clearance hole. The upper connecting seat and the lower connecting seat are located on the side of the intermediate vertical plate away from the screw rod, and the upper connecting seat and the lower connecting seat are connected to the screw rod through the clearance hole.

[0013] Specifically, a tangent guide rail is provided on the side of the middle vertical plate facing away from the lead screw, and tangent sliding seats that are slidably engaged with the tangent guide rail are respectively provided on the upper connection seat and the lower connection seat.

[0014] Specifically, the upper connection seat is provided with an upper extension extending to the side of the stripping base, and the lower connection seat is provided with a lower extension extending to the side of the stripping base. The upper extension and the lower extension are arranged in parallel. The upper blade is fixed to the upper extension, and the lower blade is fixed to the lower extension.

[0017] Specifically, it further includes a synchronous pulley assembly. The stripping drive motor and the lead screw are driven through the synchronous pulley assembly. The stripping drive motor is located between the upper substrate and the lower substrate.

[0018] Specifically, the stripping base is further provided with a blowing module for blowing air toward the mating side of the upper blade and the lower blade.

[0019] Specifically, the blowing module is a blow pipe or a seat body with multiple blow holes.

[0020] Advantages of the present utility model:

[0021] For a wire stripping and cutting mechanism of the present utility model, during use, the wire to be stripped and cut passes through between the upper blade and the lower blade. When wire stripping is required, the stripping drive motor drives the upper blade and the lower blade to approach each other to an incompletely shearing state, but there is a wire passing hole left between their teeth. The wire passing hole is smaller than the outer diameter of the wire insulation and larger than the outer diameter of the wire metal core. At this time, the wire moves relative to the teeth along the length direction, and the insulation can be peeled off to expose the metal core; when the wire needs to be cut off, the upper blade and the lower blade are fully engaged for shearing. Compared with the prior art, the same set of upper blade and lower blade can achieve wire stripping and cutting, with a simple structure and strong flexibility. Description of the Drawings

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] In practice, multiple wound wires are straightened and pulled. After reaching the wire stripping and cutting mechanism 200, first, the insulating skin at the front end of the wire is stripped, or a section of the front end of the wire is cut off in advance to make the ends of the multiple wires flush. Then, a section of wire is cut out according to the required length as a lead, and then the insulating skin at the rear end of the cut-out wire is stripped, and the obtained lead is a lead with the insulating skin at both ends stripped and the insulating skin in the middle retained.

[0035] The wire stripping and cutting mechanism 200 of this embodiment, as Figure 1 shows two groups, namely the first wire stripping and cutting mechanism 2001 located on the right for stripping / cutting the front end of the wire, and the second wire stripping and cutting mechanism 2002 located on the left for stripping / cutting the rear end of the wire. The structures of the two groups of wire stripping and cutting mechanisms are similar. Specifically, in combination with Figures 2 to 4As shown, it includes a stripping base 20, a screw rod 21 rotatably and vertically installed on the stripping base 20, a stripping drive motor 22 for driving the screw rod 21 to rotate forward and reversely, and an upper connecting seat 23 and a lower connecting seat 24 respectively threadedly connected to the screw rod 21, the upper connecting seat 23 is fixed with an upper blade 25, and the lower connecting seat 24 is provided with a lower blade 26, and the ends of the upper blade 25 and the lower blade 26 that are close to each other are respectively provided with teeth.

[0036] The threads of the screw rod 21 matched with the upper connecting seat 23 and the lower connecting seat 24 are opposite, so that the stripping drive motor 22 drives the screw rod 21 to rotate and can drive the upper blade 25 and the lower blade 26 to approach to the stripping state and the cutting state. In the stripping state, the teeth of the upper blade 25 and the teeth of the lower blade 26 bite into the insulation of the wire and leave a wire hole for the metal core of the wire to pass through; in the cutting state, the upper blade 25 and the lower blade 26 shear each other to cut the wire.

[0037] In this embodiment, the wire stripping and cutting mechanism 200 also includes a stripping transverse driving member 27 for driving the stripping base 20 to move transversely forward and backward. When in use, the wire to be stripped and cut passes between the upper blade 25 and the blade. When stripping is required, the stripping driving motor 22 drives the upper blade 25 and the lower blade 26 to approach each other to a state where they are not completely sheared, but leave a wire-passing hole between the teeth. The wire-passing hole is smaller than the outer diameter of the wire insulation and larger than the outer diameter of the wire metal core. The stripping transverse driving member 27 drives the stripping base 20 to move backward, so that the insulation from the biting position to the end of the guide wire can be pulled out to expose the metal core. In practice, as long as the wire moves relative to the teeth along the length direction, the insulation can be stripped. In this embodiment, the knife moves while the guide wire does not move. In practice, the knife can be changed to not move while the guide wire moves along the length direction, or both move at the same time, and the insulation can be pulled out. When the wire needs to be cut, the upper blade 25 and the lower blade 26 can be fully coordinated to cut. Compared with the prior art, the same set of upper blades 25 and lower blades 26 can realize the stripping and cutting of the wire, and has a simple structure and strong flexibility.

[0038] Specifically, the stripping base 20 is in a U-shape as a whole, and includes an upper base plate 201, a lower base plate 202, and an intermediate vertical plate 203 standing between the upper base plate 201 and the lower base plate 202. A reinforcing rib is provided between the lower base plate 202 and the intermediate vertical plate 203. The two ends of the screw rod 21 are mounted on the upper base plate 201 and the lower base plate 202 via bearings. The intermediate vertical plate 203 is provided with a clearance hole 2031. The upper connecting seat 23 and the lower connecting seat 24 are located on the side of the intermediate vertical plate 203 away from the screw rod 21. The upper connecting seat 23 and the lower connecting seat 24 are connected to the screw rod 21 through the clearance hole 2031. The side of the intermediate vertical plate 203 away from the screw rod 21 is provided with a tangent guide rail 28, and the upper connecting seat 23 and the lower connecting seat 24 are respectively provided with a tangent slide 29 that slidably matches the tangent guide rail 28. Such a layout has a compact overall structure and high stability.

[0039] Specifically, it further includes a synchronous pulley assembly 210. The stripping drive motor 22 and the lead screw 21 are driven via the synchronous pulley assembly 210, and the stripping drive motor 22 is located between the upper substrate 201 and the lower substrate 202.

[0040] Specifically, the upper connecting seat 23 is provided with an upper extension 231 extending to the side of the stripping base 20, and the lower connecting seat 24 is provided with a lower extension 241 extending to the side of the stripping base 20. The upper extension 231 and the lower extension 241 are arranged in parallel. The upper blade 25 is fixed to the upper extension 231, and the lower blade 26 is fixed to the lower extension 241. In particular, the upper and lower extensions 241 of the first wire stripping and cutting mechanism 2001 are relatively long, facilitating the feeding of the wire from the side of the stripping base 20.

[0041] Specifically, it further includes an upper adjustment seat 232 installed on the upper extension 231 and a lower adjustment seat 242 installed on the lower extension 241. The upper adjustment seat 232 can be longitudinally moved and then locked, and the upper blade 25 is fixed to the upper adjustment seat 232; the lower adjustment seat 242 can be longitudinally moved and then locked, and the lower blade 26 is fixed to the lower adjustment seat 242. It is used to manually adjust the initial relative position of the upper blade 25 and the lower blade 26. The specific adjustment method is as follows:

[0042] Between the upper adjustment seat 232 and the upper extension 231, and between the lower adjustment seat 242 and the lower extension 241, they are respectively combined and locked by screws through longitudinally arranged long slots 234. The upper extension 231 is threadedly engaged with an upper fine adjustment bolt 233 that abuts against the upper adjustment seat 232 downward, and the lower extension 241 is threadedly engaged with a lower fine adjustment bolt 243 that abuts against the lower adjustment seat 242 upward. When adjustment is required, taking the upper connecting seat 23 as an example, first slightly loosen the screw in its long slot 234 (still in the state of pressing the upper adjustment seat 232), then rotate the upper fine adjustment bolt 233 to abut and push the upper connecting seat 23 to move downward to a suitable position, and then fully lock the screw in the long slot 234.

[0043] In this embodiment, the stripping base 20 is further provided with a blowing module 211 for blowing air toward the mating side of the upper blade and the lower blade. The blowing module 211 is a blow pipe or a seat body with multiple blow holes.
