Description

Technical Field

[0001] The present invention relates to the technical field related to the detection of the height and flow rate of the lighter flame, and specifically to an air tank automatic flame adjustment detector. Background Art

[0002] After the lighter is processed, it is necessary to adjust the flame and detect the flow rate of the lighter white head (i.e., the flame nozzle of the lighter). Because once the lighter flame is too large, the problem of flame cross-over is likely to occur, affecting safety.

[0003] The current operation method is that manual workers need to use specific tools to insert into the lighter, clamp the lighter white head and rotate it for adjustment. Such an adjustment method undoubtedly increases the labor cost and reduces the work efficiency. At the same time, the current detection of the lighter flame flow rate, such as a lighter detection method and device disclosed in Patent Application No.: 201210412833.X, is characterized in that the steps are: arranging a row of lighters to be detected in front of the camera; the pressing mechanism presses and ignites the lighters to be detected, and then delays for a predetermined time, and the flames of each lighter to be detected are photographed by the camera, and the digital images are transmitted to the computer through the data line for analysis and processing; the computer obtains the flame size of each lighter to be detected by using the digital images and the working parameters of the camera, compares and discriminates with the standard, and outputs the qualified or unqualified signals of each lighter to be detected to the display screen for display or the corresponding alarm indicator for indication; the pressing mechanism rises and releases, and the lighters to be detected are removed, and according to the display on the display screen, the lighters with unqualified flames are picked out. The present invention uses a camera to photograph the lighter flame, which not only realizes continuity, improves the detection accuracy and speed, but also has a simpler and more reasonable device structure, greatly improving the detection efficiency. However, this structure still stays at the stage of detecting by taking pictures with a camera. Taking pictures with a camera requires multiple samplings in advance and is easily affected by external interference, thus affecting the detection accuracy. Therefore, it needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an air tank automatic flame adjustment detector to solve the problems of high labor cost, low work efficiency, and easy influence on detection accuracy by external interference in the existing adjustment of the lighter white head flame and flow rate detection as mentioned in the above background art.

The longitudinal transportation mechanism 9 includes a longitudinal pushing cylinder 901 fixed on the frame 1 and a pushing plate I 902 connected to the piston rod of the longitudinal pushing cylinder 901. The pushing plate I 902 is used to transport one group of oil tank jigs 5 from the long-side clamping group to the short-side clamping group. The lateral transportation mechanism 8 includes a lateral pushing cylinder 801 fixed on the frame 1 and a pushing plate II 802 connected to the piston rod of the longitudinal pushing cylinder 901. The pushing plate II 802 is used to transport one group of oil tank jigs 5 from the short-side clamping group to the long-side clamping group. In this embodiment, due to the lateral transportation mechanism 8 and the longitudinal transportation mechanism 9 on both sides of the two long sides of the figure-eight-shaped material-blocking transportation track, and the two longitudinal transportation mechanisms 9 are obliquely symmetrically distributed, and the two lateral transportation mechanisms 8 are obliquely symmetrically distributed. During operation, at the initial position of the figure-eight-shaped material-blocking transportation track, the lateral pushing cylinder 801 on the lateral transportation mechanism 8 on the side works to translate one group of oil tank jigs 5 transported by the finished product loading and grasping mechanism 21 towards the long-side clamping group. And the lateral transportation mechanism 8 at the initial position of the figure-eight-shaped material-blocking transportation track continues to work, continuously transporting the oil tank jigs 5. Finally, it is realized that each oil tank jig 5 is sequentially transported along the long-side clamping group along the figure-eight-shaped material-blocking transportation track until it is transported to the other side of the long-side clamping group. The longitudinal pushing cylinder 901 works to drive the pushing plate I 902 to push one group of oil tank jigs 5 flush with the pushing plate I 902 towards one of the short-side clamping groups.

[0039] Preferably, in order to clamp the product during the detection process, a clamping mechanism for clamping the lighter set in the rectangular-shaped material-blocking conveying track is further provided. The clamping mechanism includes two sets of mirror-image clamping assemblies. Each set of clamping assemblies includes a clamping cylinder 11, a clamping plate 12, a clamping positioning seat 13, and a clamping guide rail 14. The clamping cylinder 11 and the clamping guide rail 14 are fixed on the frame 1. The piston rod of the clamping cylinder 11 is connected to the clamping plate 12.

A Z-shaped pressing plate 16 for pressing the upper end surface of the lighter oil tank housing 6 is arranged on one set of clamping positioning seats 13. When one or more sets of oil tank jigs 5 move to below the detection station, at this time, the clamping cylinder 11 is driven to work, driving the front and rear clamping positioning seats 13 to move synchronously. The movement of the two clamping positioning seats 13 can change the size of the clamping opening of the front and rear symmetrical semi-clamping openings 15, and finally realize clamping of the lighter oil tank housing. In this embodiment, since this structure clamps the two sets of oil tank jigs 5, two sets of clamping mechanisms for clamping the lighter set in the rectangular-shaped material-blocking conveying track need to be provided.

[0040] Preferably, to achieve automatic conveying, a finished product blanking and grasping mechanism 17 for sending the qualified lighter set from the rectangular-shaped material-blocking conveying track onto the finished product conveying mechanism 3 is further included. A waste material opening 18 is also arranged inside the frame 1. A waste material recycling box 19 is placed below the waste material opening 18. The waste material opening 18 is located in the movement track of the finished product blanking and grasping mechanism 17 and is used to realize dropping unqualified products from the waste material opening 18 into the waste material recycling box 19 by the finished product blanking and grasping mechanism 17. This structure further includes a finished product loading and grasping mechanism 21 for sending the lighter set to be detected from the loading conveying mechanism 20 to the initial conveying point of the rectangular-shaped conveying mechanism 4. And since the finished product loading and grasping mechanism 21 and the finished product blanking and grasping mechanism 17 need to convey the products, they must have the functions of horizontal movement, vertical movement, and grasping. And since the lighter processing equipment belongs to the conventional technology in this field, the specific structures of the finished product loading and grasping mechanism 21 and the finished product blanking and grasping mechanism 17 both belong to the conventional technology in this field, so no detailed description is made here. And to improve work efficiency, the finished product loading and grasping mechanism 21 and the finished product blanking and grasping mechanism 17 in this embodiment need to grasp all the lighter oil tank housings 6 on one oil tank jig 5 at one time. And the grasping structure involved belongs to the conventional technology in this field, so no detailed description is made here.

[0041] The working principle of this structure is as follows:

[0042] First, use the feeding conveyor mechanism 20 to convey the product to the position of the feeding conveyor mechanism 20 close to the finished product feeding and grasping mechanism 21, and then use the finished product feeding and grasping mechanism 21 to convey it into the figure-eight conveyor mechanism 4. Use the lateral conveyor mechanism 8 and the longitudinal conveyor mechanism 9 on both sides of the figure-eight material-blocking conveyor track to convey the product within the figure-eight material-blocking conveyor track. After conveying it to the detection station, drive the flame-adjusting flow detection unit 7 to work. At this time, the multi-position fixed cylinder 7034 works, driving the slide plate 705 to move downward, and finally driving the flow detection sensor 707 to move downward synchronously. After contacting the solenoid valve 711, press the switch of the solenoid valve 711 to ensure that the solenoid valve 711 is powered on. Then drive the cylinder two 7035 to work, driving the positioning sleeve 712 to move upward through the hinge seat 731, and finally making the clamping openings below the two chucks 714 contract and clamp outside the flame nozzle 601 in the lighter fuel tank housing 6. At this time, drive the motor 7036 to work, and use the cooperation of the second transmission wheel 717, the first transmission wheel 716 and the transmission belt 718 to drive the flame-adjusting rod 7031 to clamp the flame nozzle 601 and rotate, so as to adjust the nozzle flow rate of the flame nozzle 601. At the same time, because the flow detection sensor 707 (it should be noted that how the flow detection sensor 707 checks the flow rate belongs to the conventional technology in this field, so it will not be described in detail here) is powered on and uses the detection rod 710 below to detect the flow rate of the flame ejected by the flame nozzle 601. Therefore, through this structure, the flame flow rate of the flame nozzle 601 in the lighter fuel tank housing 6 can be accurately grasped by using the flow sensor, ensuring that the range value is greatly reduced, and the flame size is adjusted by automatically turning the flame-adjusting rod downward to the white head of the lighter, that is, the flame nozzle 601, further improving the work efficiency and the accuracy of adjustment.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
