Description

Technical Field

[0001] The utility model relates to the technical field of the electronic cigarette industry, in particular to a laser welding device for heating mesh wires of an electronic cigarette. Background Art

[0002] The heating net of an electronic cigarette is an important component of an electronic cigarette, responsible for converting electrical energy into thermal energy, thereby heating the e-liquid and producing an atomization effect. The welding of the heating net of an electronic cigarette welds the heating net and the wire together. The existing welding of the heating net is usually completed by manual welding, and multiple wires are manually welded to one side of the heating net. Although manual welding has its advantages in some cases, it also has some significant disadvantages: (1) Manual welding may lead to unstable quality of the welding points, and there may be differences in the strength and quality of the welding, which will affect the performance of the entire heating net; (2) Manual operation is difficult to ensure the accuracy of each welding point, which may lead to uneven structure of the heating net, affecting heat distribution and atomization effect; (3) Manually welded welds are relatively fragile and are prone to cracking or falling off during high temperature or long-term use; (4) The welding quality is highly dependent on the experience and skills of the operator. Novices or workers with low technical skills may cause welding defects; (5) Manual welding requires skilled workers to operate, which increases production costs. The production speed of manual welding is slow and it is difficult to meet the needs of large-scale production. Utility Model Content

The cutter and stripping knife in the wire cutting assembly 42 are then used to cut and strip the wire to form a wire segment 2000. The wire feed driver 432 drives the wire feed frame 431 to continue moving forward and feed it into the insertion channel 121 in the wire loading and welding station 102 to facilitate welding. The wire feed driver 432 can adopt a conventional motor screw drive structure. The wire lifting driver 435 and the wire clamp opening and closing driver 434 are cylinders. The number of the wire feeding clamps 433 corresponds to the number of the wire channels 4121.

After the first lifting driver 442 drives the first lifting seat 443 to move to a suitable height, the wire segment 200 clamped by the wire feeding clamp 433 in the wire feeding assembly 43 is inserted into the elastic clamping groove 4441 of the two elastic clamping plates 444, as shown in FIG. Figure 10As shown; the second lifting driver 447 drives the second lifting seat 446 to rise, driving the bracket 445 to rise, the bracket 445 drives the wire segment 200 to rise until the wire segment 2000 is moved out from the elastic clamping groove 4441 of the elastic splint 444, as shown Figure 11 As shown, the wire segment 2000 is inserted into the insertion channel 121 of the wire loading and welding station 102 to facilitate welding.

[0044] The material strip positioning assembly 51 includes a material strip positioning pin 511 that cooperates with the material strip hole on the material strip and a positioning pin driver 512 for driving the material strip positioning pin to rise and fall. The positioning pin driver 512 is installed on the workbench 10 using a positioning stand 513. When the material strip 1000 moves to below the material strip positioning pin 511, the positioning pin driver 512 drives the material strip positioning pin 511 to descend, and the material strip positioning pin 511 is inserted into the side hole on the material strip 1000 to ensure that the material strip 1000 does not shift during welding.

[0045] The material strip clamping assembly 52 includes a clamping seat 521 and a clamping seat lifter 522 for driving the clamping seat to rise and fall. The clamping seat lifter 522 is installed on the workbench 10 through a clamping stand 523.

When the material strip is welded, the pulling pin lifting driver 63 drives the pulling pin 62 upward and inserts it into the upper hole of the material strip. The pulling translation driver 64 then drives the pulling slide 61 to move, thereby driving the welded material strip to move and provide power for the rearward movement of the material strip. The translational travel slot 13 is disposed below the pressing seat 521 and is longer than the pressing seat 521.

[0047] The workbench 10 is also provided with an inspection station 105 and a rejection station 106. The inspection station 105 is located at the rear side of the pulling station 104. The inspection station 105 corresponds to a CCD camera 70, and the rejection station 106 corresponds to a rejection mechanism 80. The welded material strip moves to the inspection station 105 and is inspected by the CCD camera 70. When there are defective products in the material strip, after the welded material strip moves to the rejection station 106, the rejection mechanism 80 is used to shear the defective products on the material strip.

The scissors lifting driver 83 is installed on the rejection slide 81, and a rejection port 14 is provided on the workbench 20. When there are defective products in the material strip, after the welded material strip moves to the rejection station 106, the rejection translation driver 84 drives the rejection slide 81 to move to the preparation position, and the scissors lifting driver 83 drives the scissors 82 to descend for shearing. After the shearing is completed, the rejection translation driver 84 drives the rejection slide 81 to move to the rejection port 15 position, and the scissors 82 open, thereby rejecting the defective products on the material strip.

[0050] To improve efficiency, the wire loading and welding stations 102, the strip positioning and pressing stations 103, the pulling stations 104, the inspection stations 105, and the rejection stations 106 in two adjacent welding lines 100 are all arranged side by side on the same workbench 10. Each of the two wire loading and welding stations 102 can be equipped with a corresponding laser welding machine 30, and each of the two inspection stations 105 can be equipped with a corresponding CCD camera 70. Two wire conveying mechanisms 40 are located on either side of the workbench 10, and the roll unwinding mechanisms 20 and the strip recovery mechanisms 90 in the two welding lines 100 are respectively arranged at the front and rear ends of the workbench 10. Furthermore, the drivers in each station can be arranged on the same stand, saving space. During welding, the two sides of the double strip are welded alternately.

[0051] The working process of the entire welding assembly line 100 is as follows: (1) The rolled heating net is placed in the unwinding reel 22, and the paper rewinder 23 rewinds the paper in the material strip. The material strip 1000 is rolled by the rubber-coated pressing roller 11 and enters the wire loading welding station 102; (2) The positioning pin driver 512 drives the material strip positioning pin 511 to descend, and the material strip positioning pin 511 is inserted into the side hole on the material strip 1000; (3) The wire in the wire reel 3000 is introduced through the wire wheel group 413, and after being straightened by the straightening seat 414, it enters the wire channel 412 of the wire seat 412 1; (4) the wire feeding clamp 433 clamps the front end of the wire, and uses the upper cutting knife 4251 and the lower cutting knife 4241 to close and cut to form the wire segment 2000. When cutting, the upper stripping knife 4252 contacts the epidermis of the wire 2000.
