Description

Technical Field

[0001] This utility model relates to the field of lighter assembly technology, and in particular to a bottom valve feeding device for assembling lighters. Background Technology

[0002] The production process of a lighter involves multiple steps, specifically from design and material preparation to final assembly and testing.

[0003] The assembly process of a lighter involves placing parts such as zinc sleeves, suction rods, adjusting sponges, and gas valves into the housing and assembling them into a complete lighter through welding or plugging.

[0004] For example, Chinese patent CN 208276378 U describes an automatic feeding and welding equipment for lighter bottom valves. The bottom valves that need to be transported to the lighter housing are neatly stacked on a conveyor table. During assembly, multiple valves are directly picked up by a robotic arm for assembly. However, as the number of lighter housings to be processed increases, the number of bottom valves required and the volume of the bottom valve transport equipment gradually increase, leading to an increase in the cost of manufacturing the equipment. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a bottom valve feeding device for assembling lighters. It solves the problem that the bottom valves that need to be transported to the lighter housing are neatly stacked on the conveyor table, and multiple valves are directly picked up by a robot for assembly. However, as the number of lighter housings to be processed increases, the number of bottom valves required and the size of the bottom valve conveying device gradually increase, leading to an increase in the cost of manufacturing the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bottom valve feeding device for assembling lighters, comprising a feeding and storage unit located beside a conveyor line, and a material taking unit for taking the bottom valve of the feeding and storage unit. The feeding and storage unit comprises a storage section and a feeding section sequentially located beside the conveyor line. The storage section has a plurality of first storage chambers and second storage chambers arranged in a staggered manner. The feeding section has a plurality of conveying chambers.

[0007] During operation, the output end of the conveying chamber is connected to the corresponding adjacent first or second storage chamber.

[0008] Furthermore, the storage section includes a positioning bar and a moving bar that slides on the positioning bar, with the first storage chamber and the second storage chamber equally spaced on the moving bar.

[0009] Furthermore, the feeding section includes a linear vibrating machine connected to the side of the positioning bar away from the moving bar, and the conveying chamber is located on the linear vibrating machine and the positioning bar.

[0010] Furthermore, a first storage chamber and a second storage chamber are located on both sides of a conveying chamber; as the moving bar moves, the first storage chamber or the second storage chamber located next to the conveying chamber is connected to the conveying chamber.

[0011] Furthermore, the lower part of the material feeding and storage unit is also provided with a top material unit, which includes multiple top bars corresponding to the lower part of multiple material storage chambers, and a first driving member connecting the top bars; when picking up materials, the contact end of the top bar extends into / out of the material storage chamber, so that the bottom valve in the material storage chamber is connected to the adsorption end of the material picking unit.

[0012] Furthermore, the contact end of the top bar is L-shaped.

[0013] Furthermore, the material handling unit includes a support frame and a first drive cylinder mounted on the support frame, as well as a second drive component connected to the output shaft of the first drive cylinder. The second drive component includes an adsorption plate and a second drive cylinder that drives the adsorption plate to move. The adsorption end is located on the side of the adsorption plate away from the second drive cylinder.

[0014] Furthermore, the adsorption plate has multiple protrusions at equal intervals on the side away from the second drive cylinder, and air passages are provided on the protrusions, with the adsorption end located at the air inlet end of the air passage.

[0015] Furthermore, the second driving component includes a receiving plate connected to the output end of the first driving cylinder, a third driving cylinder mounted on the receiving plate, the output shaft of the third driving cylinder being connected to a sliding plate, and the second driving cylinder being mounted on the sliding plate.

[0016] Furthermore, the upper part of the conveyor line is equipped with two opposing limiting guides, which are located at the lower part of the material handling unit.

[0017] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the bottom valve is conveyed in the conveying chamber. When the material taking unit does not remove the bottom valve, the solid part between the two storage chambers on the storage section blocks the discharge end of the conveying chamber to avoid ineffective conveying of the bottom valve. When the material taking unit needs to remove the bottom valve, with the forward / backward movement of the storage section, the bottom valve is stored in both discharge chambers corresponding to one conveying chamber for the material taking unit to remove. Through the above method, the number of lighter casings that can be assembled at one time is increased without increasing the equipment's footprint, thereby enhancing production efficiency and reducing production costs.

[0032] Please refer to Figure 1-7The diagram illustrates the specific structure of a preferred first embodiment of the present invention, which is a bottom valve feeding device for assembling lighters. It includes a feeding and storage unit 20 located beside a conveyor line 10, and a material-retrieving unit 30 for retrieving the bottom valve from the feeding and storage unit 20. The feeding and storage unit 20 includes a storage section 20a and a feeding section 20b sequentially located beside the conveyor line 10. The storage section 20a has multiple first storage chambers 211 and second storage chambers 212 arranged in a staggered pattern. The feeding section 20b has multiple conveying chambers 25. During operation, the output end of the conveying chamber 25 communicates with the corresponding adjacent first storage chamber 211 or second storage chamber 212. Compared to existing lighter bottom valve feeding devices, which have a relatively fixed device design for conveying the bottom valve, causing the device volume to increase with the number of lighter casings processed at one time, this method offers advantages over conventional methods. In this lighter bottom valve feeding device, the bottom valve is conveyed in the conveying chamber 25. When the material taking unit 30 does not take the bottom valve, the solid part between the two storage chambers 21 on the storage section 20a blocks the discharge end of the conveying chamber 25 to avoid ineffective conveying of the bottom valve. When the material taking unit 30 needs to take the bottom valve, as the storage section 20a pushes forward / reverses, the bottom valve is stored in both discharge chambers 21 of the corresponding conveying chamber 25 for the material taking unit 30 to take out. In this way, without increasing the equipment's footprint, the number of lighter casings that can be assembled at one time is increased, thereby enhancing production efficiency and reducing production costs.

[0033] like Figure 3 As shown, exemplarily, the storage section 20a includes a positioning bar 22 and a moving bar 23 that slides on the positioning bar 22. The first storage cavity 211 and the second storage cavity 212 are equally spaced on the moving bar 23. The positioning bar 22 is located between the moving bar 23 and the feeding section 20b, and the positioning bar 22 is mounted on the feeding section 20b, so that the moving bar 23 is suspended in the air and can slide.

[0034] In one embodiment, a fourth drive cylinder 221 is provided on one side of the positioning bar 22. The output shaft of the fourth drive cylinder 221 is connected to one side of the moving bar 23. The opposite surfaces of the moving bar 23 and the positioning bar 22 are slidably connected through a groove and a slider, so that the moving bar 23 can move smoothly under the drive of the fourth drive cylinder 221.

[0035] like Figure 3 As shown, exemplarily, the feeding unit 20b includes a vertical vibrator 24 connected to the side of the positioning bar 22 away from the moving bar 23, and a conveying chamber 25 disposed on the vertical vibrator 24 and the positioning bar 22. The vertical vibrator 24 can smoothly move its bottom valve within the conveying chamber 25 until it enters the storage chamber 21.

[0036] In one embodiment, a conveyor plate 241 is installed at the output end of the vibrating machine 24, and multiple conveying chambers 25 are equally spaced on the upper surface of the conveyor plate 241. The conveyor plate 241 is horizontal to ensure the smooth conveying of the bottom valve on it.

[0037] like Figure 4 As shown, exemplarily, a first storage chamber 211 and a second storage chamber 212 are located on both sides of a conveying chamber 25; as the moving bar 23 moves, the first storage chamber 211 or the second storage chamber 212 located beside the conveying chamber 25 communicates with the conveying chamber 25. When the first storage chamber 211 and the second storage chamber 212 are not filled, a portion of the first storage chamber 211 and the second storage chamber 212 on the conveying chamber 25 communicates with the inner cavity of the conveying chamber 25, so that the moving bar 23, driven by the fourth drive cylinder 221, can quickly allow the bottom valve inside the conveying chamber 25 to enter the first storage chamber 211 and the second storage chamber 212 when it is pushed forward or backward.

[0038] Specifically, to facilitate the bottom valve in the conveying chamber 25 to enter the first storage chamber 211 and the second storage chamber 212, the first storage chamber 211 and the second storage chamber 212 are located on the side of the moving bar 23 near the positioning bar 22, so that the bottom valve in the conveying chamber 25 can move to the top of the first storage chamber 211 and the second storage chamber 212 and enter them more accurately.

[0039] like Figure 5 As shown, for example, the lower part of the feeding and storage unit 20 is also provided with a top material unit 40. The top material unit 40 includes multiple top bars 42 corresponding to the lower part of multiple storage cavities 21, and a first driving member 43 connecting the top bars 42. When picking up materials, the contact end 41 of the top bar 42 extends into / out of the storage cavity 21, so that the bottom valve in the storage cavity 21 is connected to the suction end 31 of the picking unit 30. The storage cavity 21 is connected to the moving bar 23, and a corresponding top bar 42 is provided at the lower part of the storage cavity 21. The top bar 42 can extend into / out of the storage cavity 21 by the drive of the first driving member 43, so that the bottom valve in the storage cavity 21 can more easily contact the suction end 31 of the picking unit 30, so as to avoid the bottom valve from separating from the suction end 31 when the picking unit 30 delivers the bottom valve.

[0040] Specifically, the first driving component 43 includes a fifth driving cylinder 431 and a connecting bar 432 installed on the output shaft of the fifth driving cylinder 341. Multiple top bars 42 are installed at equal intervals on the side of the connecting bar 432 away from the output shaft of the fifth driving cylinder 341. When the material handling unit 30 has not removed the bottom valve from the storage chamber 21, the top bars 42 are located at the lower part of the storage chamber 21 and support the bottom valve, preventing it from falling out of the storage chamber 21. When the material handling unit 30 removes the bottom valve from the storage chamber 21, the conveying shaft of the fifth driving cylinder 341 pushes the connecting bar 432 towards the moving bar 23, causing the top bars 42 on the connecting bar 432 to insert into the storage chamber 21, ensuring a tight fit between the bottom valve in the storage chamber 21 and the suction end of the material handling unit 30.

[0041] It should be noted that the top bar 42 is inserted into the storage cavity 21 only after the bottom valves are stored in both the first storage cavity 211 and the second storage cavity 212 that make up the storage cavity 21, and the moving bar 23 is reset so that the top bar 42 is adapted to the storage cavity 21. Only then will the fifth drive cylinder 341 drive the top bar 42 to be inserted into the storage cavity 21, so as to avoid the top bar 42 from hitting the bottom wall of the moving bar 23.

[0042] like Figure 5 As shown, for example, the contact end 41 of the top bar 42 is L-shaped. When the contact end of the top bar 42 is L-shaped, it can better support the bottom valve and push the bottom valve to move by adapting to the inner cavity of the bottom valve.

[0043] like Figure 2 As shown, exemplarily, the material handling unit 30 includes a support frame 32 and a first drive cylinder 33 mounted on the support frame 32, and a second drive member 34 connected to the output shaft of the first drive cylinder 33. The second drive member 34 includes an adsorption plate 341 and a second drive cylinder 342 that drives the adsorption plate 341 to move. The adsorption end 31 is located on the side of the adsorption plate 341 away from the second drive cylinder 342. The first drive cylinder 33 drives the second drive member 34 to move laterally, while the second drive member 34 drives the adsorption plate 341 to move longitudinally, so that the adsorption end 31 of the adsorption plate 341 can move from above the conveyor line 10 to above the moving bar 23, insert into the storage cavity 21 to remove the bottom valve, and be conveyed into the conveyor line 10.

[0044] like Figure 6As shown, for example, the adsorption plate 341 has multiple protrusions 3411 at equal intervals on the side away from the second drive cylinder 342. Each protrusion 3411 has an air passage 3412, and the adsorption end 31 is located at the air inlet of the air passage 3412. To better retrieve the bottom valve inside the storage chamber 21 after the adsorption plate 341 is aligned with the moving strip 23, multiple protrusions 3411 corresponding to the storage chamber 21 are installed at equal intervals on the lower end of the adsorption plate 341. These protrusions 3411 are adapted to fit the storage chamber 21, and the bottom valve inside the storage chamber 21 is retrieved by inserting the protrusions 3411 into the storage chamber 21.

[0045] It should be noted that the upper air passage 3412 of the protrusion 3411 is located in the middle of the lower end of the protrusion 3411. When the air passage 3412 is connected to the air extraction equipment, a negative pressure will be formed at the air inlet end of the air passage 3412. After contacting the bottom valve, the bottom valve will be adsorbed and transported to the top of the conveyor line 10. When the air extraction equipment stops operating, the negative pressure at the air inlet end of the air passage 3412 will disappear, and the bottom valve will naturally fall into the lighter casing inside the conveyor line 10 for assembly.

[0046] like Figure 2 As shown, exemplarily, the second driving member 34 includes a receiving plate 343 connected to the output end of the first driving cylinder 33, a third driving cylinder 344 mounted on the receiving plate 343, and a sliding plate 345 connected to the output shaft of the third driving cylinder 344. The second driving cylinder 342 is mounted on the sliding plate 345. To allow the protrusion 3411 to be better inserted into the storage cavity 21, the second driving member 34 includes two driving cylinders, one of which is the third driving cylinder 344. The third driving cylinder 344 is mounted on the receiving plate 343, which is connected to the first driving cylinder 33. The second driving cylinder 342 is mounted on the sliding plate 345, which is connected to the output shaft of the third driving cylinder 344.

[0047] Specifically, the conveying direction of the second drive cylinder 342 and the drive cylinder 344 is longitudinal, so as to facilitate the docking of the protrusion 3411 with the lighter housing inside the conveying line 10 and the material storage cavity 21 on the moving bar 23.

[0048] like Figure 7 As shown, for example, the upper part of the conveyor line 10 is also provided with two opposing limiting guides 50, which are located below the material handling unit 30. The limiting guides 50 include a guide plate 51 installed on one side of the upper part of the conveyor line 10, and a guide strip 52 installed on the other side of the upper part of the conveyor line 10. The guide strip 52 is located below the guide plate 51, and the guide plate 51 is located below the adsorption plate 341.

[0049] Specifically, both the guide bar 52 and the guide plate 51 are provided with holes 53 that adapt to the protrusion 3411, and the holes 53 on the guide bar 52 are semi-circular holes that communicate with the outside. The side of the guide bar 52 away from the adsorption plate 341 is connected to the output shaft of the sixth drive cylinder 54. When the bottom valve adsorbed at the lower end of the protrusion 3411 needs to be fed, the bottom valve can enter the lighter housing on the conveyor line 10 without deviation through the guidance of the guide bar 52 and the holes 53 on the guide plate 51.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
