Description

Technical Field

[0001] The present invention relates to the technical field of detection devices for lighter processing, and specifically relates to a dry detector for lighters. Background Art

[0002] A lighter is a small fire-making device, mainly used for lighting fires, smoking, and also for cooking and other fire-making purposes. The main components of a lighter are a firing mechanism and a gas storage tank. When the firing mechanism operates, a spark bursts out and shoots towards the gas area to ignite the gas. The firing mechanism is the most active part in the evolution of lighters and is also the part with a relatively complex structure. According to the characteristics of the firing mechanism, lighters can be divided into 6 types: flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters, and microcomputer lighters. As a fire-starting tool, lighters have been promoted and applied for a hundred years.

[0003] In recent years, China has become the world's largest lighter manufacturing base, with an annual output accounting for more than 2 / 3 of the world's total sales. Since the production process of lighters is relatively simple and the production cost is relatively low, there are many small lighter production plants in China. During the production process of lighters, it is necessary to detect air leakage at the upper and lower parts of the lighters. Therefore, there is, for example, a patent with the patent number: 202011188801.7 and the patent name "A Detection Device for Lighter Production and Its Use Method", which includes a bottom plate, a first conveyor belt, a second conveyor belt, a first cylinder, a gas leakage detection component, a fire detection component, and a blanking component. The first conveyor belt is fixedly connected to one side of the top of the bottom plate, and an installation box is fixedly connected to the top of the bottom plate and on one side of the first conveyor belt. The structure of the present invention is compact and the operation is simple and convenient. By cooperating the first conveyor belt with the second conveyor belt and the first cylinder, automatic feeding can be realized, which is beneficial to reducing labor costs. By the gas leakage detection component, air leakage of the produced lighters can be detected, which is beneficial to improving the safety of lighter storage. By the fire detection component, ignition detection of the lighters can be carried out, so as to select the lighters, thereby improving the qualified rate of lighters, which is beneficial to improving the user satisfaction. By the blanking component, the original manual blanking method can be replaced, which is beneficial to improving the production efficiency of lighters. However, this structure has the following problems: 1. During detection, a single probe is used for detection, resulting in low detection efficiency; 2. This structure mainly detects the air leakage condition of the upper part of the lighter, while ignoring the air leakage condition of the air inlet point at the bottom of the lighter, thus resulting in the situation that the final lighter is scrapped due to air leakage at the bottom because the air inlet point at the bottom of the lighter is not detected, ultimately reducing the qualified rate of the lighter. Therefore, there are still problems of low detection efficiency and high scrapping rate due to improper detection in the current detection of lighters. Summary of the Invention

In this embodiment, there are 20 gripper seats 16 in total. Therefore, 20 lighters 38 can be grasped at one time. After grasping 20 qualified lighters 38 at one time, then drive the third linear guide rail assembly 15 to move back and forth, and then transport it above the blanking through-hole 6.

Two positioning detection sensors 281 for detecting the arrival of the bottom shell 3 are provided on the upper table surface 10-1. The magnetic coupling rodless cylinder 282 is electrically connected to the control cabinet 4. The left side of the left clamping plate 283 is used to position the left side of the bottom shell 3. During operation, by driving the magnetic coupling rodless cylinder 282 to work, the magnetic coupling rodless cylinder 282 drives the right clamping plate 284 to move to a position close to the left clamping plate 283. Then, as the conveyor belt 2 transports the bottom shell 3 to the position of the right clamping plate 284, it is ensured that the right clamping plate 284 is inserted into the bottom shell 3 containing the lighter 38, and the right clamping plate 284 is placed inside the lighter 38.

A push plate 36 that pushes the lighter 38 on the upper table surface 10-1 into the waste product conveying channel 34 is connected to the piston rod of the double-piston pushing cylinder 35. During operation, when the device detects that the product has air leakage, the operator places it on the upper table surface 10-1. Then, when a certain number is placed, by driving the double-piston pushing cylinder 35 to work, the push plate 36 is driven to push all the lighters 38 into the waste product conveying channel 34. Later, a storage box can be placed in front of the waste product conveying channel 34 for storage. Then, later, the device needs to wait for the gas detection sensor to return to the measurable value, and the device automatically continues the next cycle of operation and detection.

[0043] The specific working principle of the present invention is as follows:

[0044] During operation, first place a lighter 38 in each lighter installation groove 301 in the bottom case 3, and ensure that the bottom of the lighter 38 is located at the hollow 302. Then, convey it to the left side of the upper table surface 10-1 through the conveyor belt 2. After that, when it is conveyed to the position of the upper and lower detection area 5 by the conveying component 28, at this time, the lower detection device 9 and the upper detection device 10 that drive up and down work synchronously to simultaneously detect the bottom and the upper part of the lighters 38 in a row on the bottom case 3 for air leakage. After the detection is completed, it is conveyed to the blanking position. At this time, drive the pneumatic clamping component 14 to clamp a row of lighters at the same time and put them into the blanking through hole 6, and then collect them using the finished product collection box 8. At the same time, during the detection process, once a leaking product is found, the leaking product can be taken by hand and placed in sequence on the right side of the upper table surface 10-1. After a row is full, drive the double-piston push cylinder 35 to work, and the push plate 36 works to push a row of scrapped lighters 38 into the scrap conveying channel 34. Therefore, through the setting of the present invention, the bottom and the upper part of the lighter are simultaneously detected for air leakage, which improves the work efficiency and further reduces the scrap rate. At the same time, during the detection process, the upper air and the lower air are detected simultaneously, and multiple are detected at one time, which further improves the detection efficiency. In addition, it should be noted that one bottom case of the present invention can hold 50 lighters 38, and the hollow 302 structure can adapt to the detection of different products, realizing the automatic displacement of the products on the conveyor belt 2 when they reach the position, and performing upper and lower inspections. At the same time, in the actual operation process, the position can be fine-tuned according to the detection position, and the number of products detected in each cycle is 20; only by setting the hollow can the lower leakage be detected, and at the same time, the structure of the upper table surface 10-1 is set to form the ventilation required for the detection site to realize air circulation; the upper and lower cooperation constitutes 40 sensing gases, and 20 are detected simultaneously up and down each time, improving the detection efficiency; in addition, the equipment has a single detection corresponding to a single flow regulating valve 11, and a unified air suction device in the later stage realizes unique regulation; in addition, in order to improve safety and avoid affecting the detection of surrounding products, the equipment needs to wait for the sensor to return to the measurable value, and the equipment automatically continues the next cycle of operation for detection. Through the setting of the present invention, the final output of the whole machine reaches 90,000 / 10 hours (±5% error rate).
