It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The working principle of the utility model is as follows: Figure 1 , Figure 2 As shown, the fully automatic assembly machine for the ignition spring of the lighter includes a frame 1 and an electric control box 2, a working frame 3 is arranged above the electric control box 2, one side of the working frame 3 is connected to an operating display screen 11 through a mechanical arm for operating the entire device, and the display screen can display the working status;

[0036] The frame 1 is provided with a feed conveyor belt 4 and a discharge conveyor belt 5 for feeding and discharging products. The jig positioning mechanism 6 includes two mounting plates 601 and an access plate 602 arranged above and below. The mounting plate 601 is provided with a plurality of mounting holes for placing the lighter casing. The feed conveyor belt conveys the product to be processed onto the mounting plate through the access plate and is positioned using a cylinder.

[0037] like Figure 3 As shown, the needle receiving mechanism 7 is used to receive the ignition spring, which is arranged on one side of the working frame 3, and includes: a vibration plate 701, a straight vibration flow channel 702, a needle receiving mechanism 703, a needle receiving upper sliding cylinder 704, a needle receiving slider pushing cylinder 705 and a needle receiving positioning block 706;

[0038] The vibration plate 701 is arranged on the working frame 3 through the vibration plate base 711, and the upper end is connected to the direct vibration flow channel 702, and the ignition spring enters the pointer after being sorted through the vibration plate and the direct flow channel; the connecting needle is pushed upward by the connecting needle upper sliding cylinder, and the connecting needle upper sliding cylinder 704 is arranged on the direct vibration fixing seat 707 through the connecting needle upper sliding cylinder fixing seat 708;

[0039] The pin pusher slider cylinder moves the pin forward and backward, pushes it into the pin positioning block for blowing, and allows the spring to enter the press-fit mechanism; the pin pusher slider cylinder 705 is fixedly arranged on the upper side of the pin upper slide cylinder 704, and the telescopic shaft of the pin pusher slider cylinder 705 is connected to the pin fixing slider 710 through the pin slider fixing plate 709;

[0040] like Figure 4 As shown, the press-fitting mechanism 8 is used for press-fitting the ignition spring and the lighter housing, and is arranged above the jig positioning mechanism 6; the press-fitting mechanism 8 includes: a downward pressure cylinder 801, a Z-axis carriage 802, a positioning block 803, a pressure needle 804, a spring 805, a fixing block 806 and a Z-axis servo motor 807;

A pressure needle fixing block 810 is designed above the two positioning blocks, and a spring herringbone slider 811 is designed below. After the ignition spring is blown by the needle receiving mechanism, it directly falls into the spring herringbone slider.

[0042] The downward pressure cylinder base 808 is arranged on the work frame 3, and the Z-axis carriage 802 is moved up and down by the downward pressure cylinder 801;

[0043] The downward pressure cylinder 801 drives the entire press-fitting structure to move downward. After reaching the specified position, the Z-axis servo motor 807 moves downward to drive the fixed block 806 to move downward. The number of spring herringbone sliders and pressure needles matches the number of mounting holes in a row on the mounting plate. After one press-in is completed, the Z-axis servo motor 807 drives the upward movement, and the feeding linear slide rail 9 moves the mounting plate to align the lighters in the next row of mounting holes on the mounting plate, and the Z-axis servo motor is used to press down again for installation;

[0047] Specific implementation method: 50 inflated lighter casings in a box are put into the feed conveyor belt in turn, and enter the jig positioning mechanism through the conveyor belt. Two boxes of 100 casings are installed on the plate. After the positioning plate is pressed down for positioning, the vibration plate sends the ignition spring into the straight vibration flow channel, and the ignition spring is connected from the flow channel to the connecting needle through the connecting needle mechanism. The connecting needle sliding cylinder slides up, and the connecting needle cylinder works, and the connecting needle is pushed into the connecting needle positioning block for blowing, so that the ignition spring passes through the material tube into the spring herringbone slider, and then is pressed in by the pressing mechanism. 20 ignition springs are pressed in each time, and 5 rows of casings are pressed in through Y-axis stepping. After completion, the Y-axis module moves the product to the unloading position, and the unloading cylinder pushes the product out and enters the discharge conveyor plate to complete the work.
