Description

Technical Field

[0001] This utility model relates to the technical field of testing electronic ignition devices for lighters, specifically a push-button assembly for a piezoelectric testing device for electronic lighters. Background Technology

[0002] Current electronic lighters mainly consist of components such as the casing, nozzle, rocker arm, electronic igniter (also called electronic ignition device), and cap. The electronic igniter works by using piezoelectric ceramics inside. Applying pressure to both sides of the ceramic plate generates a directional flow of electrons, which are then conducted through a wire. Due to this point discharge, an electric spark is generated at the lighter's outlet. This spark comes into contact with the butane released by the lighter, igniting the flame. Therefore, the electronic igniter is a crucial component.

[0003] After the electronic igniters are manufactured, they must undergo voltage testing and sorting to remove products with no voltage or low voltage, ensuring the quality and performance of each igniter.

[0021] Example 1

[0022] Please see Figures 1-4As shown in this embodiment, a pressing assembly for an electronic lighter piezoelectric testing device includes a fixed support plate 1. The fixed support plate 1 is equipped with a conveying mechanism 2 for conveying electronic lighters and a primary pressing mechanism 3. The primary pressing mechanism 3 strikes the electronic lighter head conveyed on the conveying mechanism 2 to generate voltage for primary testing. The fixed support plate 1 is also equipped with a secondary pressing mechanism 4. The secondary pressing mechanism 4 strikes the electronic lighter head conveyed on the conveying mechanism 2 to generate voltage for secondary testing. The secondary pressing mechanism 4 includes two guide rods 401. The slide 402, cylinder seat 403, and first cylinder 404 are provided. The lower ends of two guide rods 401 are fixed to the fixed support plate 1, and the upper ends of the two guide rods 401 are fixed to the cylinder seat 403. The first cylinder 404 is fixed above the cylinder seat 403. The slide 402 is slidably connected between the two guide rods 401. The piston rod of the first cylinder 404 passes through the cylinder seat 403 and is connected to the slide 402. One or more push-button pins 405 are spaced apart below the slide 402, and the push-button pins 405 are located directly above the conveying trajectory of the conveying mechanism 2.

[0023] Preferably, for ease of transport, the conveying mechanism 2 includes a rotary motor 201, a main drive wheel 202, and an auxiliary drive wheel 203. The rotary motor 201 is fixed to the bottom of the fixed support plate 1, and the output shaft of the rotary motor 201 passes through the fixed support plate 1 and is connected to the center of the main drive wheel 202. The auxiliary drive wheel 203 is rotatably connected to the fixed support plate 1, and a drive belt 204 is provided between the auxiliary drive wheel 203 and the main drive wheel 202.

[0024] Preferably, in order to position the conveyed electronic lighter, the fixed support plate 1 is also provided with a positioning plate 5, one side of which abuts against one side of the transmission belt 204, and the positioning plate 5 is close to one side of the transmission belt 204 when the second press needle 405 is pressed down.

[0025] Preferably, for ease of operation, the single-press mechanism 3 includes a mounting plate 301, a horizontal plate 302, a second cylinder 303, a first pressing needle 304, and a slider 305. The mounting plate 301 is fixed to the fixed support plate 1 at the bottom, and the horizontal plate 302 is fixed to the top of the mounting plate 301. The second cylinder 303 is fixed to the horizontal plate 302, and the piston rod of the second cylinder 303 passes through the horizontal plate 302 and is connected to the slider 305. The first pressing needle 304 is disposed below the slider 305 and serves as a guide during pressing and moving. The upper part of the mounting plate 301... The device is also equipped with a guide rail 306, on which the slider 305 is slidably connected. During operation, when the vibratory feeder feeds the electronic igniter 13, when the electronic igniter 13 is delivered to one side of the limiting base plate 6, the second cylinder 303 is driven to work, which drives the pressing needle 304 to move closer to the horizontally placed electronic igniter 13, thus pressing the electronic igniter 13 once. At this time, the existing detection equipment is used to perform piezoelectric detection on the pressed electronic igniter 13. It should be noted that the piezoelectric detection equipment used in the later stage of this structure is a conventional technology in this field, so it will not be described in detail.

[0026] Preferably, to further position the conveyed electronic lighter, a limiting base plate 6 is provided on the side of the fixed support plate 1 relative to the side of the transmission belt 204. A feed inlet 7 is provided on the side of the limiting base plate 6 relative to the lower position near the pressing needle 304. When the electronic lighter 13 is fed by the vibratory feeder after the feed inlet 7 is added, the electronic lighter 13 is inserted through the feed inlet 7 and moves towards the secondary pressing mechanism 4 as the transmission belt 204 rotates. In order to limit the feed inlet and ensure that the electronic lighter can only move with the conveying direction of the conveying mechanism 2, a limiting bracket 12 is provided on the fixed support plate 1 to limit one side of the feed inlet 7. By adding the limiting bracket 12, the feed inlet 7 is limited on one side. Finally, when the electronic lighter 13 is fed by the vibratory feeder, it can only move from the feed inlet 7 towards the secondary pressing mechanism 4 as the transmission belt 204 rotates.

[0027] Preferably, for products that automatically discharge scrap in the later stage, the limiting base plate 6 is provided with a scrap port 8, the cylinder seat 403 is provided with a longitudinal plate 9 on one side, and a third cylinder 10 is fixed behind the longitudinal plate 9. The piston rod of the third cylinder 10 is connected to a push rod 11 for sending the defective product out of the scrap port 8. When the later detection equipment detects that the piezoelectric detection of the electronic igniter 13 is unqualified, when the unqualified electronic igniter 13 moves to the scrap port 8, the third cylinder 10 is driven to work. The push rod 11 is pushed to move towards the waste inlet 8, and the defective products are finally sent out from the waste inlet 8. It should be noted that after the equipment is installed, the electronic lighter 13 is placed horizontally, and the waste inlet 8 and the feed inlet 7 are both located at the front end of the conveying mechanism 2, while the primary pressing mechanism 3 and the secondary pressing mechanism 4 are both located at the rear end of the conveying mechanism 2. The conveying mechanism 2 is a conveying process from right to left. Therefore, during the conveying process, the electronic lighter 13 will not fall off the transmission belt 204.

[0028] During operation, when the vibratory feeder feeds the electronic igniter 13, when the electronic igniter 13 is conveyed to one side of the limiting base plate 6, the second cylinder 303 is driven to work, causing the pressing needle 304 to move closer to the horizontally placed electronic igniter 13, thus pressing the electronic igniter 13 once; then, as the rotary motor 201 works, it drives the main drive wheel 202, the auxiliary drive wheel 203, and the drive belt 204 to rotate synchronously to convey the electronic igniter 13. When it is conveyed to the secondary pressing mechanism 4, the first cylinder 404 is driven to work, causing the slide 402 to move closer to the electronic igniter. The lighter 13 is activated by pressing it twice. At this time, the existing detection equipment is used to perform piezoelectric detection on the activated electronic lighter 13. It should be noted that the piezoelectric detection equipment used in this structure is conventional technology in this field, so it will not be described in detail. Then, as the transmission belt 204 moves to the left, unqualified products can be selected and discharged through the waste port 8. Qualified products can be transported to the left for collection. Therefore, through this structure, the electronic lighter 13 can be activated by pressing it twice for piezoelectric detection, which further improves the detection accuracy.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
