[0034] Please refer to Figures 1-25 , which shows the specific structure of the preferred first embodiment of the present application, is a lighter assembly processing equipment, which is used for assembling and processing lighter housings. The device is mainly used for installing the screw sleeve and the bottom valve on the lighter housing;

[0035] The lighter assembly equipment comprises a conveying mechanism 10 provided with a conveying carrier 13 on a workbench 1, and a lighter housing loading mechanism 20, a screw sleeve loading mechanism 30, a first carrier overturning mechanism 40, a bottom valve loading mechanism 50, and a second carrier overturning mechanism 60 which are sequentially and spacedly arranged along the conveying direction of the carrier.

[0036] Specifically, the lighter assembly processing equipment, including providing conveying mechanism 10, conveying mechanism 10 is provided on the workbench 1, for conveying lighter shell in turn through shell feeding mechanism 20, screw sleeve feeding mechanism 30, the first carrier turnover mechanism 40, bottom valve feeding mechanism 50, the second carrier turnover mechanism 60;In addition, the shell feeding mechanism 20 and the screw sleeve feeding mechanism 30 between the shell leak detection mechanism 70 is also provided, the screw sleeve feeding mechanism 30 and the first carrier turnover mechanism 40 between the screw sleeve leak detection mechanism 80 is provided, the screw sleeve leak detection mechanism 80 and the first carrier turnover mechanism 40 between the screw sleeve welding mechanism 90 is provided, the bottom valve feeding mechanism 50 and the second carrier turnover mechanism 60 between the bottom valve leak detection mechanism 100 is provided, the bottom valve leak detection mechanism 100 and the second carrier turnover mechanism 60 between the bottom valve welding mechanism 110 is provided, the lighter shell by the shell discharge mechanism 120 is discharged through the second carrier turnover mechanism 60, thus completing the assembly processing of the lighter shell.

[0037] As shown in Figure 3 In one embodiment, the conveying mechanism 10 includes a "mouth" shaped annular track 11 and a cylinder 12 provided at each corner of the annular track 11, the output shaft of each cylinder extends into the annular track 11 and pushes the carrier 13 to convey in the annular track 11. The annular track 11 surrounds the workbench 1 to convey the carrier 13 thereon so that the lighter shell in the carrier 13, the shell feeding mechanism 20, the shell leak detection mechanism 70, the screw sleeve feeding mechanism 30, the screw sleeve leak detection mechanism 80, the screw sleeve welding mechanism 90, the first carrier turnover mechanism 40, the bottom valve feeding mechanism 50, the second carrier turnover mechanism 60, the bottom valve leak detection mechanism 100, the bottom valve welding mechanism 110 and the shell discharge mechanism 120 are processed in the processing area. After processing, the screw sleeve and the bottom valve are installed on the lighter shell, and the screw sleeve and the bottom valve are fixed, so that the screw sleeve and the bottom valve cannot be easily separated from the lighter shell.

[0038] Specifically, the lighter shell is conveyed by the shell feeding mechanism 20 into the carrier 13 which can slide in the annular track 11, and the carrier 13 moves in the annular track 11 under the push of the side wall cylinder 12 of the annular track 11. First, the shell leak detection mechanism 70 is passed to determine whether the position of the shell placed on the carrier 13 is correct. Then, the screw sleeve is placed in the lighter shell by the screw sleeve feeding mechanism 30. Then, the screw sleeve leak detection mechanism 80 is passed to detect whether the screw sleeve is missing on the lighter shell. Then, the screw sleeve is locked by the screw sleeve welding mechanism 90. Then, the first carrier turnover mechanism 40 is passed to turn over the lighter shell, so that the lower end of the lighter shell faces upward and the upper end faces downward. Then, the bottom valve is installed in the lighter shell by the bottom valve feeding mechanism 50. Then, the bottom valve leak detection mechanism 100, the bottom valve welding mechanism 110 and the second carrier turnover mechanism 60 are passed to turn over the lighter shell twice. Finally, the lighter shell is discharged by the shell discharge mechanism 120. Thus, the preliminary assembly of the lighter shell is completed.

[0039] In addition, the carrier 13 fits closely with the inner cavity of the circular track 11 , so that the carrier 13 will not deviate when moving within the circular track 11 , thereby ensuring the stability of each processing mechanism when processing the carrier 13 within the circular track 11 .

[0040] like Figure 4 As shown, in one embodiment, the casing loading mechanism 20 includes a conveyor belt 21 for conveying a material tray 22, a material ejecting unit 23 provided at the end of the conveyor belt 21, and a guide member 24 provided between the output end of the material ejecting unit 23 and the circular track 11; the material tray 22 is provided with a plurality of rows of placement cavities 221 for placing the casings; the guide member 24 is provided with guide grooves 241 at intervals;

[0041] The ejector unit 23 includes a first pneumatic push rod 231, a dividing bar 232 provided on the output shaft of the first pneumatic push rod 231, and a row of ejector pins 233 provided on the dividing bar 232;

[0042] When the conveyor belt 21 transports the material tray 22 to a predetermined position, the lighter housing enters the guide groove 241. The first pneumatic push rod 231 drives the ejector pin 233 upward, pushing the lighter housing in the placement cavity 221 along the guide groove 241 into the carrier. To ensure that the lighter housing can enter the carrier 13 along the guide groove 241, a through opening 112 is formed in the bottom wall of the annular track 11. The through opening 112 corresponds to the guide groove 241 and a carrier 13, allowing the lighter housing to smoothly enter the carrier through the guide groove 241.

[0043] Specifically, the conveyor belt 21 is conveyed by a belt, and the tail end of the conveyor belt 21 is located below the circular track 11, so that the material tray 22 conveyed on the conveyor belt 21 can be aligned with the opening 112 below the circular track 11. The material tray 22 is provided with a plurality of equally spaced placement cavities 221. The placement cavities 221 pass through both ends of the material tray 22, and the lower end diameter of the placement cavity 221 is smaller than the upper end diameter to prevent the lighter casing placed in the placement cavity 221 from falling.

[0044] The first pneumatic push rod 231 in the ejecting unit 23 is fixed on the support foot of the inner cavity of the body 1, and the indexing bar 13 installed on the output shaft of the first electric push rod 231, and the row of ejector pins 233 installed on the top of the indexing bar 13 correspond to the placement cavity 221 on the material tray 22, so that the first electric push rod 231 drives the lower indexing bar 13 to drive the ejector pins 233 upward and insert them into the placement cavity 221 on the material tray 22, so that the lighter casing in the placement cavity 221 enters the carrier 13 along the guide groove 241 on the guide member 24.

[0045] In order to receive the material disc 22 on the conveying belt 21, the different placing cavities 221 containing the lighters on the material disc 22 can be guided by the corresponding guide 24 as the conveying belt 21 is conveyed. A guide conveying table 25 opposite to the conveying belt 21 is installed on the workbench 1, and the conveying end of the guide conveying table 25 extends below the lighter discharging mechanism 120. Since the conveying belt 21 is a belt conveyor, if the ejector pin 233 penetrates the conveying belt 21, it will affect the normal conveying of the belt. Therefore, the guide 24 is arranged above the guide conveying table 25, and the ejector pin 233 can penetrate the guide conveying table 25 and contact the guide 24, so as to facilitate the pushing of the lighters in the placing cavities 221 on the material disc 22 moved to the guide conveying table 25 into the guide groove 241.

[0046] In addition, the three sides of the annular track 11 are solid plate bodies, and the two through openings 112 arranged at the bottom of the annular track 11 correspond to the lighter feeding mechanism 20 and the lighter discharging mechanism 120, so as to ensure that the lighters in the carrier 13 will not fall in the annular track 11.

[0047] As shown in the drawings, Figure 5 In one embodiment, the lighter leak detection unit 70 includes a first track plate 71 installed on one side of the upper end of the annular track 11, and a first receiving block 72 installed on the other side of the upper end of the annular track 11 opposite to the first track plate 71. A detection block 73 is slidably connected to the upper portion of the first track plate 71, and a row of detection strips 731 are installed at equal intervals on the side of the detection block 73 close to the first receiving block 72. A fourth pneumatic push rod 74 is connected to the side of the detection block 73 away from the first receiving block 72, and the fourth pneumatic push rod 74 is installed on the first track plate 71 with the output end connected to the first receiving block 72. When the lighters received are moved to the working area of the lighter leak detection unit 25, the detection block 73 moves with the fourth pneumatic push rod 74, so that the detection strips 731 are close to the first receiving block 72. At this time, if the placing position of the lighters on the carrier 13 deviates, it can be observed by the contact between the detection strips 731 and the lighters, so as to facilitate the workers to adjust the position of the lighters on the carrier 13 at any time.

[0048] It should be noted that the number of detection strips 731 is matched with the number of lighters on one carrier 13, and the detection strips 731 correspond to the through opening 131.

[0049] As shown in the drawings, Figure 6 In one embodiment, the screw sleeve feeding mechanism 30 includes a feeding unit 31 for conveying screw sleeves, a first material stopping unit 32 arranged at the output end of the feeding unit 31 and preventing the screw sleeves from falling out of the feeding unit, an adjusting unit 33 arranged below the output end of the feeding unit 31 and used for adjusting the direction of the screw sleeves, a carrier moving unit 34 arranged between the adjusting unit 33 and the feeding unit 31, a second material stopping unit 35 arranged at the output end of the adjusting unit 33 and preventing the screw sleeves from falling out of the adjusting unit 33, and a positioning unit 36 arranged below the adjusting unit 33 and used for clamping the lighters.

[0050] The feeding unit 31 comprises a sleeve screening machine 311 and a conveying line 312, the sleeve screening machine 311 is operated to adjust the position of the sleeve and move to the conveying line 312, the conveying line 312 is divided into a main line 312a connected with the sleeve screening machine 311 and a branch line 312b connected with the main line 312a, the sleeve is arranged and conveyed to the inner cavity of the branch line 312b from the upper part of the main line 312a by the sleeve screening machine 311;

[0051] The first stopping unit 32 comprises a guide plate 321 and a stopping part 322, the branch line 312b conveys the sleeve to the through hole 321a in the guide plate 321, the stopping part 322 is operated to make the abutting end 322a of the stopping part 322 can penetrate into the through hole 321a, the stopping part 322 is divided into a top strip plate 3221 which can be inserted into the through hole 321a, the abutting end 322a is located at the end of the insertion end of the top strip plate 3221, and a first electric push rod 3222 is arranged beside the guide plate 321 and connected with the top strip plate 3221;

[0052] The adjusting unit 33 comprises a first motor 331, a rotating part 332 arranged at the output end of the first motor 331, a row of bearing holes 333 arranged on the rotating part 332, and two abutting parts 334 arranged on the surface wall of the rotating part 332 and opposite to each other;

[0053] When the sleeve falling on the guide plate 321 is conveyed to the predetermined position by the moving unit 34, the sleeve enters the abutting part 334, is conveyed to the bearing hole 333 by the abutting part 334 with the rotation of the rotating part 332, and the first motor 331 drives the rotating part 332 to rotate to adjust the orientation of the sleeve and convey the sleeve to the second stopping unit 35;

[0054] The moving unit 34 comprises a second electric push rod 341, a moving plate 342 arranged between the guide plate 321 and the abutting part 334 and connected with the output end of the second electric push rod 341, and a row of transfer holes 342a arranged on the moving plate 342, the moving plate 342 is driven by the second electric push rod 341 to move the sleeve conveyed by the guide plate 321 or the sleeve in the transfer hole 342a to the abutting part 334;

[0055] The second stopping unit 35 comprises a third electric push rod 351 and a baffle 352 arranged between the abutting part 334 and the positioning unit 36, the baffle 352 is driven by the third electric push rod 351 to separate from the abutting part 334 by moving to block the sleeve in the abutting part 334, or to separate from the discharge port of the abutting part 334 by moving, so that the sleeve in the abutting part 334 moves along the baffle 352 to the carrier 13;

[0056] The positioning unit 36 comprises a first abutting block 361 and a movable first clamping plate 362 arranged at the top of the annular track 11, and a fourth electric push rod 363 connected with the first clamping plate 362. When the carrier 13 carrying the lighter shell moves to the predetermined position, the fourth electric push rod 363 drives the first clamping plate 362 to move towards the first abutting block 361 and clamps the lighter shell on the carrier 13. The screw sleeve screening machine 31 comprises a storage box 31a for placing the screw sleeves. When the screw sleeve screening machine 31 is in operation, the screw sleeves in the storage box 31a are transmitted to the conveying line 312 connected to one side of the storage box 31a through vibration. The conveying line 312 is composed of a plurality of main lines 312a and branch lines 312b. The main line 312a is in the shape of a column, and two adjacent main lines 312a are spliced together. The screw sleeves move in the gap between the connection of the two adjacent main lines 312a and are conveyed to the branch line 312b. In addition, the inlet end of the branch line 312b corresponds to the gap between the connection of the two main lines 312a, and the main line 312a is in communication with the inner cavity of the storage box 31a.

[0057] Specifically, the screw sleeves that move to the gap between the two adjacent main lines 312a along with the vibration of the screw sleeve screening machine 31 contain a plurality of screw sleeves, but only one screw sleeve can be accepted by one branch line 312b corresponding to one gap at a time. In order to ensure that the screw sleeves can smoothly enter the branch line 212b from the main line 312a and not fall off the main line 312a, a connecting plate 313 is installed on the opposite sides of the upper part of the main line 312a. A rotatable rotating drum 314 is inserted into the connecting plate 313. The rotating drum 314 is located on the upper end surface of the main line 312a, and one side of the rotating drum 314 is in close contact with the upper end of the main line 312a, so that the screw sleeves passing through the rotating drum 314 are arranged in order on the main line 312a.

[0058] Because the rotating drum 314 is in the shape of a column and / or contains bristles, in order to avoid the rotation of the rotating drum 314 affecting the position of the screw sleeves passing through the rotating drum 314, a shielding plate 315 is installed on the main line 312a. The shielding plate 315 extends to the lower part of the rotating drum 314 and is in abutting contact with the rotating drum 314, so that the screw sleeves passing through the rotating drum 314 will not be thrown out due to the rotating force of the rotating drum 314 when it rotates, but will move to the gap a between the two adjacent main lines 312a below the shielding plate 315.

[0059] But a carrier 13 in a cavity 221 only need a screw, and the screw in the branch pipe 312b is arranged in a row, in order to avoid the damage and loss of the screw caused by displacement when the screw is adjusted, a row of through holes 321a is opened on the guide plate 321 connected to the output end of the branch pipe 312b, when the screw in the branch pipe 312b passes through the through hole 321a, the first electric push rod 3222 in the stop part 322 beside the guide plate 321 is driven to push the top strip plate 3221 to approach the guide plate 321, until the top strip on the top strip plate 3221 is inserted into the through hole 321a, to limit the screw in the through hole 321a from being discharged, and to provide enough adjustment space and time for the previously discharged screw.

[0060] At this time, the screw discharged from the output end of the through hole 321a falls into the transfer hole 342a opened on the moving plate 342 below the guide plate 321, and the moving plate 342 can be translated by the driving of the second electric push rod 341, when the transfer hole 342a is connected with the through hole 321a, the top strip on the top strip plate 3221 inserted into the through hole 321a is moved out of the through hole 321a by the first electric push rod 3222, so that the screw in the through hole 321a can fall into the transfer hole 342a, and then the first electric push rod 3222 is reset to make the top strip on the top strip plate 3221 reinserted into the through hole 321a to block the screw in the through hole 321a from falling. When the screw falls into the through hole 321a, the moving plate 342 is moved by the second electric push rod 341 to make the through hole 321a correspond to the hole on the receiving part 334, and then it slides down and contacts the surface wall of the rotating part 332.

[0061] With the driving of the first motor 331, the rotating part 332 rotates, so that the bearing hole 333 on the rotating part 332 corresponds to the hole on the receiving part 334, and the screw in the hole on the receiving part 334 falls into the bearing hole 333, and with the 90° rotation of the rotating part 332, the screw in the bearing hole 333 completes the direction adjustment, and corresponds to the hole on the receiving part 334 again, so that the screw in the bearing hole 333 after the direction adjustment can fall into the hole, and is blocked by the baffle 352, so that the baffle 352 limits the screw in the bearing hole 333 from being discharged.

[0062] It should be noted that the receiving part 334 is divided into an upper receiving part and a lower receiving part, the upper receiving part is located above the rotating part 332, and the moving plate 342 moves on the top surface of the upper receiving part, and the lower receiving part is located below the rotating part 332, and the baffle 352 moves below the lower receiving part.

[0063] In addition, the baffle 352 can be moved below the lower receiving part by the driving of the third electric push rod 351, so that the baffle 352 can close or open the screw in the hole on the lower receiving part.

[0064] When the baffle 352 moves away, the sleeve in the hole of the lower supporting part can enter the carrier 13 along the guide groove provided on the baffle 352.

[0065] When the sleeve enters the carrier 13, the first clamping plate 362 is driven by the fourth electric push rod 363 to move towards the lighter shell on the carrier 13, and clamps the lighter shell to make the lighter shell close to the first abutting block 361, so that the lighter shell does not deviate when the sleeve is screwed on.

[0066] As shown in the drawings, Figure 12 In one embodiment, when the carrier 13 passes through the sleeve feeding mechanism 30, it reaches the output end of the sleeve leak detection mechanism 80, and the sleeve leak detection mechanism 80 includes a fifth pneumatic push rod 801 arranged above the annular track 11, the output shaft of the fifth pneumatic push rod 801 faces the top of the carrier 13, and a first detection plate 802 is fixed thereon, one side of the first detection plate 802 close to the carrier 13 is F-shaped, and a row of first detection needles 803 are inserted thereon, springs 804 are sleeved on the first detection needles 803, and the two ends of the springs 804 are respectively connected with the two end walls of the first detection plate 802. When the carrier 13 moves below the first detection needles 803, the fifth pneumatic push rod 801 drives the first detection plate 802 to drive the first detection needles 803 to move towards the lighter shell on the carrier 13, and the first detection needles 803 contact the sleeve on the lighter shell. When the sleeve is not installed or installed incorrectly, the top end of the first detection needle 803 moves upward, so that the sensor installed on the top of the first detection plate 802 or the production personnel can judge the placement of the sleeve in the lighter shell according to the upward movement of the first detection needle 803.

[0067] As shown in the drawings, Figure 13 In one embodiment, the sleeve welding head mechanism 90 includes a sixth pneumatic push rod 91 arranged above the carrier 13, the output shaft of the sixth pneumatic push rod 91 corresponds to the upper end of the carrier 13, and a sleeve welding head 92 is fixed on the output shaft of the sixth pneumatic push rod 91. When the lighter shell on the carrier 13 passes through the sleeve leak detection mechanism 80 and reaches below the sleeve welding head 92, the sleeve welding head 92 installed below the sixth pneumatic push rod 91 contacts the sleeve in the lighter shell on the carrier 13, and the sleeve and the lighter shell are tightly connected through ultrasonic heating, so as to avoid separation of the sleeve and the lighter shell.

[0068] In addition, in order to ensure the stability of the sleeve and the lighter shell when they are fixed, two opposite first clamping seats 93 are fixed on both sides of the annular track, and the two first clamping seats 93 are pushed by a seventh electric push rod 94, so that the two opposite first clamping seats 93 can clamp the lighter shell on the carrier 13 by being pushed by the seventh electric push rod 94, so as to fix the sleeve in the lighter shell by the sleeve welding head 92.

[0069] As shown in the drawings, Figure 13As shown, in one embodiment, the circular track 11 is provided with a cutout (111) at locations corresponding to the first carrier flipping mechanism 40 and the second carrier flipping mechanism 60. The first carrier flipping mechanism 40 includes a first bracket 41 placed in the cutout 111, a first receiving tube 42 rotatable in the first bracket 41, and a first meshing transmission unit 43 provided between the first bracket 41 and the first receiving tube 42.

[0070] The first meshing transmission unit 43 includes a first gear 431 provided on the surface wall of the first receiving tube 42, a second gear 432 provided at the lower portion of the first receiving tube 42 and meshing with the first gear 431, and a second motor 433 connected to the second gear 432.

[0071] After the screw sleeve is placed in the lighter housing and welded, the cylinder 12 pushes the carrier 13 to move into the inner cavity of the first accommodating tube 42. The second motor 433 drives the second gear 432 to rotate, which in turn drives the first accommodating tube 42 to rotate 90 degrees. The second motor 433 drives the second gear 432 to rotate, which in turn drives the first accommodating tube 42 to rotate, causing the carrier 13 moved into the first accommodating tube 42 to flip over. This flips the lighter housing on the carrier 13 so that the bottom of the lighter housing faces upward and the top faces downward, making it easier to install the bottom valve on the lighter housing.

[0072] like Figure 16 As shown, for example, the annular track 11 starts from the truncation 111 corresponding to the first accommodating tube 42, and there is a layer height a at both ends. The outlet end of the first accommodating tube 42 is connected to the guide bar 14, which is inclined and one end away from the first accommodating tube 42 is overlapped on the bottom wall of the annular track 11. The guide bar 14 contacts the bottom of the lighter shell in the carrier 13. Because the lighter shell in the carrier 13 is longer, the original top and bottom of the lighter shell are reversed after the carrier 13 is turned over. At this time, the top of the lighter shell will be partially suspended in the inner cavity of the annular track 11. When the bottom valve is on the bottom of the lighter shell, it may This causes the top of the lighter casing to be damaged. For this purpose, the two ends of the circular track 11 after the truncation opening 111 is opened are set to be one high and one low. The height difference between the two ends is called the floor height a. In order to avoid the lighter casing in the carrier 13 being separated from the carrier 13 due to the height difference when moving from the circular track 11 at the high end to the circular track 11 at the low end, a guide bar 14 is installed on the bottom wall of the circular track 11 at the low end, and one end of the guide bar 14 is overlapped with the bottom wall of the outlet end of the first accommodating tube 42. The guide bar 14 covers the floor height to avoid the lighter casing and the carrier 14 being separated when the carrier 13 moves with the height difference conversion.

[0073] like Figure 17As shown, in one embodiment, the bottom valve feeding mechanism 50 comprises a feeding unit (51) for conveying the bottom valve, a third stop unit 52 movably arranged at the output end of the feeding unit 51, a taking unit 53 arranged at the top of the storage end of the third stop unit 52, and a first positioning unit 54 arranged above the carrier 13 for clamping the lighter shell.

[0074] The feeding unit 51 comprises a bottom valve conveying plate 511 and a linear vibrator 512, and the linear vibrator 512 is operated to make the bottom valve conveying plate 511 translate to convey the bottom valve into the third stop unit 52;

[0075] The third stop unit 52 comprises a positioning strip 521 connected to the output end of the bottom valve conveying plate 511, a receiving strip 522 slidingly arranged on one side of the positioning strip 521 adjacent to the annular track 11, and a fifth electric push rod 523 connected to the output end of the positioning strip 521, and the receiving strip 522 is provided with a row of receiving openings 5221, and the fifth electric push rod 523 drives the receiving strip 522 to translate left and right to make the bottom valve be received into the receiving openings 5221;

[0076] The taking unit 53 comprises a second pneumatic push rod 531, a third pneumatic push rod 532 arranged at the output end of the second pneumatic push rod 531, and a taking member 533 arranged at the output end of the third pneumatic push rod 532;

[0077] When the cylinder 12 pushes the carrier 13 to reach below the taking member 533, the second pneumatic push rod 531 drives the taking member 533 to move from above the carrier 13 to above the receiving openings 5221, and the taking member 533 clamps the bottom valve in the receiving openings 5221 under the drive of the third pneumatic push rod 532, and then the second pneumatic push rod 531 and the third pneumatic push rod 532 are reset to move to convey the bottom valve clamped by the taking member 533 into the lighter shell;

[0078] The first positioning unit 54 comprises a second abutting block 541 arranged at the top of the annular track 11 opposite to the first abutting block 541, a second clamping plate 542 movably arranged, and a sixth electric push rod 543 connected to the second clamping plate 542, when the carrier 13 carrying the lighter shell moves to the predetermined position, the sixth electric push rod 543 drives the second clamping plate 542 to move towards the second abutting block 541, and clamps the lighter shell on the carrier 13. The bottom valve feeding mechanism 50 is the subsequent step of the first carrier overturning mechanism 40, and the bottom valve feeding mechanism 60 comprises a bottom valve conveying plate 511 mounted on the workbench 1, and the bottom valve conveying plate 511 is fixed with a linear vibrator 512 at the bottom end, and the linear vibrator 512 is vibrated to make the bottom valve translate on the bottom valve conveying plate 511 until being stored in the receiving strip 522.

[0079] In order to reduce the size of the whole device, the number of bottom valves on the bottom valve conveying plate 511 is less than the number of receiving openings 5221 on the receiving strip 522, and the number of receiving openings 5221 corresponds to the number of lighters on the bottom valve 13. When the bottom valve on the bottom valve conveying plate 511 needs to be conveyed to the receiving opening 5221, the receiving strip 522 is driven to move left and right on the positioning strip 521 by the fifth electric push rod 523, so that the receiving opening 5221 on the receiving strip 522 can receive the bottom valve into the receiving opening 5221 by moving.

[0080] Because the bottom valve conveying needs to be balanced, and the bottom valve stored in the receiving opening 5221 on the receiving strip 522 cannot be directly conveyed to the carrier 13, a material taking unit 53 is installed on the workbench 1 beside the bottom valve conveying plate 511.

[0081] With the pushing of the second pneumatic push rod 531 in the material taking unit 53, the second pneumatic push rod 531 drives the third pneumatic push rod 532 to move left and right, that is, to move from above the carrier 13 to above the receiving strip 522, or to move from above the receiving strip 522 to above the carrier 13, and the third pneumatic push rod 532 moves up and down. When the second pneumatic push rod 531 drives the third pneumatic push rod 532 to move left and right, the material taking piece 533 fixed on the output shaft of the third pneumatic push rod 532 moves upward, so that it does not interfere with the carrier 13 or the receiving strip 522, ensuring the normal movement of the material taking piece 533. When the material taking piece 533 moves to the upper part of the carrier 13 or the receiving strip 522, the material taking piece 533 takes out the bottom valve on the receiving strip 522 or places the bottom valve on a row of suction accessories 5331 on the bottom of the material taking piece 533 into the carrier 13 by the downward pressing of the third pneumatic push rod 532.

[0082] It should be noted that the extrusion strip 524 is arranged below the receiving strip 522, and the extrusion strip 524 corresponds to the receiving opening 5221. The bottom end of the extrusion strip 524 is fixed with the eighth electric push rod 525. When the material taking piece 533 moves to above the receiving opening 5521, the extrusion strip 524 is inserted into the receiving opening 5521 by the pushing of the eighth electric push rod 525, so as to push the bottom valve in the receiving opening 5521 into the suction accessories 5331 on the bottom of the material taking piece 533.

[0083] In addition, in order to avoid the movement of the lighter on the carrier 13 when the bottom valve is placed, the second clamping plate 542 is driven to move towards the second interference block 541 by the sixth electric push rod 534, so as to clamp the lighter on the carrier 13, making it more stable when the bottom valve is installed.

[0084] As Figure 20As shown in the figure, in one embodiment, the bottom valve leak detection mechanism 100 is a subsequent step of the bottom valve loading mechanism 50. The bottom valve leak detection mechanism 100 includes a seventh pneumatic push rod 101 arranged at the top end of the carrier 13. The output shaft of the seventh pneumatic push rod 101 is fixed with a second detection plate 102, which is consistent with the first detection plate 802 and is in the shape of F. A row of second detection needles 103 is inserted into the second detection plate 102.

[0085] Further, when the lighter shell with the installed bottom valve moves to the position below the second detection plate 102 with the carrier 13, the second detection plate 102 drives the second detection needles 103 to contact the bottom valve of the lighter shell by starting the seventh pneumatic push rod 101. The user can detect whether the bottom valve installed on the lighter shell is properly installed by judging whether the top end of the second detection needle 103 moves.

[0086] As shown in the figure, Figure 21 In one embodiment, the bottom valve welding mechanism 110 is a subsequent processing step of the bottom valve leak detection mechanism 100. The bottom valve welding mechanism 110 includes an eighth pneumatic push rod 1101 fixed on the upper part of the carrier 13. The output shaft of the eighth pneumatic push rod 1101 is fixed with a bottom valve welding head 1102. The middle part of the lower end surface of the bottom valve welding head 1102 is provided with a groove 1103, the caliber of which is matched with the size of the bottom part of the lighter shell. When the lighter shell with the installed bottom valve moves to the position of the bottom valve welding head 1102 with the carrier 13, the bottom valve welding head 1102 is driven to move close to the top surface of the carrier 13 by the eighth pneumatic push rod 1101, and the bottom valve on the lighter shell is extruded through the groove 1103 to make the bottom valve embedded in the lighter shell. The bottom valve is fixed in the lighter shell by ultrasonic heating.

[0087] Further, in order to ensure that the bottom valve welding head 1102 extrudes the bottom valve on the lighter shell and the lighter shell on the carrier 13 deviates, two second clamping seats 1104 are arranged on the upper part of the annular track. The two second clamping seats 1104 are located on both sides of the bottom valve welding head 1102. The opposite ends of the two second clamping seats 1104 are connected with a ninth electric push rod 1105 fixed on the annular track. The movement of the ninth electric push rod 1105 makes the two second clamping seats 1104 close to each other and clamp the lighter shell arranged on the carrier 13, so as to facilitate the extrusion processing of the bottom valve welding head 1102 on the bottom valve of the lighter shell.

[0088] As shown in the figure, Figure 23 In one embodiment, the second carrier overturning mechanism 60 includes a second support 61 placed in another cutting opening 111, a second containing pipe 62 rotatably arranged in the second support 61, and a second meshing transmission unit 63 arranged between the second support 61 and the second containing pipe 62.

[0089] The second meshing transmission unit 63 includes a third gear 631 provided on the outer wall of the second receiving tube 62, a fourth gear 632 provided at the lower portion of the second receiving tube 62 and meshing with the third gear 631, and a third motor 633 connected to the fourth gear 632.

[0090] After the bottom valve is placed on the lighter housing, the cylinder 12 pushes the carrier 13 to move to the inner cavity of the second receiving tube 62, and the third motor 633 drives the fourth gear 632 to rotate and drive the second receiving tube 62 to rotate 90 degrees.

[0091] Specifically, the second carrier flipping mechanism 60 is located in a subsequent processing step of the bottom valve welding mechanism 110. After the bottom valve is placed on the lighter housing and welded, the cylinder 12 pushes the carrier 13 to move into the second accommodating tube 62. The second motor 433 drives the second gear 432 to rotate, which in turn drives the first accommodating tube 42 to rotate 90 degrees. The third motor 633 drives the fourth gear 632 to rotate, which in turn drives the second accommodating tube 62 to rotate, causing the carrier 13 moved into the second accommodating tube 62 to perform a second flip. This flips the carrier 13 onto the lighter housing, so that the bottom of the lighter housing faces downward and the top faces upward, facilitating the discharge of the lighter housing from the unloading mechanism 70.

[0092] like Figure 24 As shown, in one embodiment, the unloading mechanism 120 is located in the subsequent step of the second flipping unit 110, and the unloading mechanism 120 includes a ninth pneumatic push rod 1201 installed on the annular track 11, the output end of the ninth pneumatic push rod 1201 corresponds to the top of the carrier 13, and the output end of the ninth pneumatic push rod 1201 is fixed with a moving bar 1202, and a plurality of extension bars 1203 corresponding to the number of lighter shells on the carrier 13 are fixed at equal intervals on the lower part of the moving bar 1202. As the ninth pneumatic push rod 1201 pushes, the moving bar 1202 drives the extension bar 1203 to squeeze the lighter shell in the carrier 13 through the upper opening 112 of the annular track 11, and then moves to the guide member 24 fixed on the lower end surface of the annular track 11, so that the assembled lighter shell moves to the material tray 22 through the guide groove 241 on the guide member 24.

[0093] It should be noted that the casing loading mechanism 20 and the unloading mechanism 120 are adjacent to each other, and as shown above, the guide member 24 on the unloading mechanism 120 is consistent with the guide member 24 in the casing loading mechanism 20, and both are used to move the lighter casing. In addition, in order to prevent the lighter casing from falling off when moving in the guide groove 241 on the guide member 24, a detachable baffle 242 covering the guide groove 241 is provided on the guide plate 24 corresponding to the unloading mechanism 120. The baffle 242 can prevent the lighter casing in the guide groove 241 from accidentally falling off.

[0094] The above merely describes preferred embodiments of the present application, and is not intended to limit the technical scope of the present application in any way. Any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application shall still fall within the technical scope of the present application.
