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 positioning and pressing device for a heating sheet and a lead wire. 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 sheet roll welded with lead wires disclosed in a Chinese patent document with the publication number of CN217986689U belongs to the technical field of electronic cigarettes, and includes a metal substrate. A heating mesh sheet main body is stamped in the middle of the metal substrate. Two lead wires are symmetrically welded to both ends of the heating mesh sheet main body. The two lead wires 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 sequentially connected to form a metal strip. And two semi-circular notches are symmetrically opened on both sides of one end of the metal substrate far away from the lead wire. And after adjacent two metal substrates are connected, the semi-circular notches are butted to form a positioning hole. This heating mesh sheet roll welded with lead wires can utilize the metal substrate to improve the overall strength of the heating mesh sheet main body, thereby initially ensuring the service life of the heating mesh sheet main body, and cooperating with the lead wires to supply power to the heating mesh sheet main body, thereby ensuring the stability of power supply to further ensure the service life of the heating mesh sheet main body. One metal substrate can correspond to two lead wires (pins, wires), 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 die through manual placement, and then a pre-etched heating mesh is covered on the top layer, and then the die is clamped on a laser welding equipment platform for welding. However, the heating mesh welded manually has large and insecure welding points, is prone to false soldering and virtual soldering phenomena, and at the same time has low production capacity and wastes a large amount of labor force.

[0004] Subsequently, automated pin welding equipment emerged. For example, a Chinese patent document with the publication number CN215966882U discloses a device for welding pin wires of a heating mesh sheet in two directions, including a laser welding device and two heating mesh sheet stepping mechanisms. Each of the two heating mesh sheet stepping mechanisms includes a conveying platform, and the feeding directions of the two conveying platforms are opposite. A welding station is arranged on the conveying platform. A peeling 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 peeled by the peeling mechanism and convey them to the welding station. An upper pressing mechanism and a lower pressing mechanism for fitting the heating mesh sheet 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 sheet and the pin wires at the welding station, realizing the automatic production of welding pin wires of two heating mesh sheets by the same laser welding machine and improving the utilization rate of the laser welding device.

[0005] Another example is that a Chinese patent document with the publication number CN210413020U discloses a spot welding device for a heating sheet, including a wire feeding and cutting device for conveying a lead wire to a heating sheet and capable of cutting the lead wire, and a spot welding device for spot welding the lead wire to the heating sheet. Both the wire feeding and cutting device and the spot welding device are arranged on a base. It uses an automated device to replace the manual soldering method to realize the welding of the pins of the e-cigarette heating sheet, greatly improving the efficiency and ensuring the quality.

[0006] Currently, when the applicant assembles and welds a metal substrate and pins, the coiled wire is first cut according to a preset length, and then the insulating skin at the end of the wire is removed to expose the metal core. Multiple wires are arranged side by side. Before laser assembly welding, several wires are first positioned at the bottom of the metal substrate. In the prior art, it is difficult to accurately position between the wire and the metal substrate, affecting the assembly welding quality. Summary of the Invention
