Description

Technical Field

[0001] The utility model relates to the technical field of processing heating components of electronic cigarettes, and in particular to a wire welding machine with a defective product marking function. Background Art

[0002] The electronic cigarette heats the smoke oil by heating the heating wire arranged inside it to achieve heating atomization, such as a heating mesh coil with a lead welded therein disclosed in the Chinese patent document with the publication number CN217986689U, which belongs to the technical field of electronic cigarettes and includes a metal substrate, a heating mesh body is stamped in the middle of the metal substrate, two leads are symmetrically welded at both ends of the heating mesh body, the two leads are parallel to each other and extend out of one end of the metal substrate, and the metal substrate is provided with a plurality of leads, which are connected in sequence to form a metal coil, and two semi-annular grooves are symmetrically opened on both sides of the end of the metal substrate away from the lead, and after the two adjacent metal substrates are connected, the semi-annular grooves are butt-jointed to form a positioning hole. The heating mesh coil with a lead welded therein can use the metal substrate to improve the overall strength of the heating mesh body, thereby preliminarily ensuring the service life of the heating mesh body, and cooperate with the lead to supply power to the heating mesh body, thereby ensuring the stability of the power supply, so as to further ensure the service life of the heating mesh body. One metal substrate may correspond to two leads (pins), or may correspond to other numbers, such as four.

[0003] In the process of welding the heating network of electronic cigarettes, manual welding or automatic single-strip welding is generally used at present; for manual welding, the heating network pins are manually cut, and the pins are placed on the welding mold by manually placing a plate, and then the pre-etched heating network is covered on the top layer, and then the mold is clamped on the laser welding equipment platform for welding. The manually welded heating network has large and unstable welding points, which is prone to false welding. At the same time, the production capacity is low and a lot of labor is wasted.

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

[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 metal substrate is in the form of a strip and is conveyed step by step along a fixed track of the workbench to complete the welding of the pins and wires. After the coiled metal substrate is welded with the pins and wires, it is rewound. For defective products with welding defects, the existing technology also collects them without distinction. In this way, it is difficult to distinguish the defective heating sheets when assembling the electronic cigarette atomizer core later. The assembled heating core is prone to short circuit or even failure to heat, affecting production efficiency. Summary of the invention

[0039] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

The transplanting lifting seat 552 is provided with a transplanting needle 555 for inserting the metal substrate. The transplanting base 51 is provided with a transplanting linear driving module 554 for driving the transplanting support seat 551 to move along the moving direction of the metal substrate.

[0041] Specifically, the transplanting linear drive module 554 is located beside the transplanting channel 54 , and the transplanting support seat 551 extends to the top of the transplanting channel 54 , so that the transplanting needle is located directly above the transplanting channel 54 .

[0042] Specifically, substrate guide plates 56 are respectively provided below the unwinding mechanism 52 and the rewinding mechanism 53. The substrate guide plates 56 are provided with a horizontal connecting section 561 and an arc-shaped guiding section 562. The horizontal connecting section 561 is connected to the end of the transplanting channel 54 to guide the entry and exit of the metal substrate.

[0043] When in use, the strip metal substrate wound in the unwinding mechanism 52 is unwound, and the metal substrate passes through the transplanting groove 54 for welding process. After the wire is welded, the metal substrate is wound into the winding mechanism 53. The transplanting lifting cylinder 553 drives the transplanting lifting seat 552 and the transplanting needle to move downward, and the transplanting needle 555 is inserted into the hole of the metal substrate. The transplanting linear drive module 554 drives the transplanting support seat 551, the transplanting lifting seat 552, the transplanting needle 555 and the metal substrate to move together, so as to realize the step-by-step movement of the metal substrate.

[0044] In this embodiment, the transplanting channel 54 includes a baffle portion 541 and a supporting portion 542 arranged vertically, and a gap is reserved between the baffle portion 541 and the supporting portion 542 for the metal substrate to pass through.

[0050] After the metal substrate and the wire are welded, the visual inspection module 3 is used to detect the integrity of the wire welding, and the background control feeds back the detection signal to the defective product marking mechanism 600, which cuts the designated welded pins according to the signal fed back by the visual inspection module 3. In this way, even if the metal substrate with poor wire welding is rolled up, it can be easily identified during subsequent use, avoiding the defective heating sheet from entering the next step of the heating core assembly process, thus ensuring product quality. The principle of the visual inspection module 3 is to judge whether the welding is qualified by comparing the difference between the captured image and the background standard image. The visual inspection technology is a prior art and will not be elaborated here.
