DETAILED DESCRIPTION

[0107] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

The seventh workstation 7 comprises a seventh conveyor line 71 , on which are provided an air hood assembly mechanism 72 , a steel wheel assembly mechanism 73 , a pressure plate assembly mechanism 74 , a lighter flint quality detection device 8 and a lighter finished product shipping mechanism 9 .

[0109] More specifically, the first workstation 1 is also called the assembly station for the assembly body, bottom cover and shell component, including a first frame 11, on which a first shell feeding mechanism 1200 is provided, and a first spacing feeding robot 1400 fixedly connected to the first frame 11 is provided on the side close to the unloading end of the first shell feeding mechanism 1200, and a first circulating conveying mechanism 300 is also provided on the first frame 11, and the first shell feeding mechanism 1200 is connected with the first circulating conveying mechanism 1300 through the first shell feeding mechanism 1200, and also includes a first part guiding mechanism 1100 and a first bottom cover assembly mechanism 1600 arranged on the first frame 11, and the first part guiding mechanism 1100 and the first bottom cover assembly mechanism 1600 are both located on the side of the first circulating conveying mechanism 1300, wherein the first loading structure 1225 includes a vibration plate; a first transfer robot capable of transferring the lighter assembled at the first workstation 1 to the third workstation 3 is provided between the first workstation 1 and the third workstation 3. The structure of the first transfer robot is similar to that of the second discharge assembly robot 2900, except for the clamping structure.

[0110] The first shell feeding mechanism 1200 includes a first shell conveyor line 1201 arranged on the first frame 1, and the first shell conveyor line 1201 includes a first No. 1 straight conveying section 1202 and a first No. 2 straight conveying section 1203. One end of the first No. 1 straight conveying section 1202 is connected to a first loading structure 1205, and the first No. 1 straight conveying section 1202 and the first No. 2 straight conveying section 1203 are connected through a first turning structure 1204. The inner surface of the first turning structure 1204 is arc-shaped, and a first shell grouping component 1211 is also provided on the side of one end of the first No. 2 straight conveying section 1203 away from the first No. 1 straight conveying section 1202.

[0111] In the present invention, when in use, the lighter shell is conveyed to the unloading end by the first shell feeding mechanism 1200, the first spacing feeding manipulator 1400 picks up the lighter shell in the first shell feeding mechanism 1200 and then spacing it, and then places it in the first circulation conveying mechanism 1300, and circulates it in the first circulation conveying mechanism 1300, and sequentially passes through the first parts guiding mechanism 100 and the first bottom cover assembly mechanism 1600 to complete the corresponding assembly. Therefore, the present invention realizes the whole process from feeding, spacing, conveying to assembly through mechanical automation, and the automation degree is relatively high.

[0112] When in use, the lighter shell in the vibration plate is transported to the first turning structure 1204 through the first straight conveying section 1202, and then continues to be transported by the first second straight conveying section 1203 after the conveying direction is changed by the first turning structure 1204. Therefore, the present invention sets a first turning structure 1204 with an arc-shaped inner surface between the first first straight conveying section 1202 and the first second straight conveying section 1203 with different conveying directions, which simply and conveniently realizes a smooth transition between conveying lines in different directions.

[0113] The first turning structure 1204 includes a first turning conveying section 1206 having an arc-shaped conveying trough 205 therein, and both ends of the first turning conveying section 1206 are respectively fixedly connected to the first straight conveying section 1202 and the first straight conveying section 1203. The first turning structure 1204 also includes a first turning conveying motor 1207 located above the first turning conveying section 1206, and a first brush 208 is also fixedly connected to the output shaft of the first turning conveying motor 1207.

[0114] Preferably, the cross section of the first brush 208 is circular, and the edge of the first brush 208 is tangent to the edge of the arc conveying groove 205. The first turning conveying motor 1207 drives the first brush 208 to rotate, so as to assist the lighter housing in the arc conveying groove 205 to perform turning conveying.

[0115] A first guide plate 1209 is disposed above the first No. 1 straight conveying section 1202, the first No. 2 straight conveying section 1203 and the first turning conveying section 1206. The first guide plate 1209 is fixedly connected to the first No. 1 straight conveying section 1202, the first No. 2 straight conveying section 1203 or the first turning conveying section 1206, and a first guide channel 1210 is disposed between two first guide plates 1209 disposed opposite to each other. In this way, during the conveying process, the upper end of the lighter housing is located in the first guide channel 1210, and can be guided by the two first guide plates 1209, thereby preventing the lighter housing from having positional deviation during the conveying process.

[0116] A first shell grouping component 1211 is also provided on the side of one end of the first second linear conveying section 1203 away from the first first linear conveying section 1202. The first shell grouping component 1211 is used to group several lighter shells into one group, and in the subsequent assembly process, the groups are used as units for simultaneous assembly operations.

[0117] Specifically, the first housing grouping component 1211 includes a first mounting housing 1212 fixedly connected to the first second linear conveying section 1203, a first driving slider 1213 is slidably connected in the first mounting housing 1212, one end of the first driving slider 1213 is drivingly connected to a power source (not shown in the figure) through a first pulling block 1214, and the power source can be a cylinder. The first driving slider 1213 is drivingly connected to two first grouping rod bodies 1216 through a first driving steering structure 1215. The first driving steering structure 1215 includes two first driving grooves 1218 with opposite inclination directions opened on the first driving slider 1213 and a first protrusion 1219 fixedly connected to the first grouping rod body 1216, the first driving grooves 1218 are arranged one-to-one with the first grouping rod body 1216, and the first protrusion 1219 is embedded in the first driving groove 1218.

[0118] When in use, the power source drives the first pulling block 1214, thereby driving the first driving slider 1213 to slide. During the sliding process, the first driving groove 1218 is relatively displaced with the first protrusion 1219. Figure 3 As shown, at this time, one of the two first grouping rods 1216 is pushed outwards, and the other is retracted inwards. When grouping, the first grouping rod 1216 on the left side of the figure is pushed out first to play a limiting role, and the lighter shell stops at the first grouping rod 1216, and then another first grouping rod 1216 is used to push out, so that the lighter shell between the two first grouping rods 1216 is artificially separated from the front and back and divided into one group. This is repeated to achieve grouping of all lighter shells.

[0119] Preferably, the end of the first grouping rod body 1216 closer to the first feeding structure 1225 in the conveying direction is fixedly connected with a first guide portion 1217, and the width of the first guide portion 1217 gradually decreases from one end close to the first grouping rod body 1216 to the other end. This makes it easy to insert the first grouping rod body 1216 into the adjacent lighter housing, thereby achieving front and rear grouping.

[0120] When in use, the lighter shell in the vibration plate is transported to the first turning structure 1204 through the first No. 1 straight conveying section 1202, and the first turning conveying motor 1207 is started, and the first turning conveying motor 1207 drives the first brush 208 to rotate, and the first brush 208 assists the lighter shell in the arc conveying groove 205 to turn and transport, and then the first No. 2 straight conveying section 1203 continues to transport after changing the conveying direction, until the first shell grouping component 1211. At this time, the power source drives the first pulling block 1214, thereby driving the first driving slider 1213 to slide, and during the sliding process, the first driving groove 1218 is relatively displaced with the first protrusion 1219, and as shown in FIG. 3, at this time, one of the two first grouping rods 1216 is pushed outward, and the other is retracted inward. When grouping, the first grouping rod 1216 on the left side of the figure is first pushed out to play a limiting role. The lighter shell stops at the first grouping rod 1216, and then another first grouping rod 1216 is used to push out. In this way, the lighter shells between the two first grouping rods 1216 are artificially separated from the front and back and divided into a group. This is repeated to achieve grouping of all lighter shells. Therefore, the present invention sets a first turning structure 1204 with an arc-shaped inner surface between the first No. 1 straight conveying section 1202 and the first No. 2 straight conveying section 1203 with different conveying directions, which simply and conveniently realizes a smooth transition between conveying lines in different directions.

[0121] The first spacing feeding robot 1400 includes a first mounting frame 1401 and a plurality of first clamping assemblies 1403 connected to the first mounting frame 1401 via a first driving assembly 1402, and a first spacing assembly 1404 is also provided between the first driving assembly 1402 and the first clamping assembly 1403, which can drive two adjacent first clamping assemblies 1403 to move closer to or away from each other, and the first clamping assemblies 1403 are arranged in sequence and connected to the first spacing assembly 1404.

[0122] When in use, after the lighter shell is vibrated and fed by the vibration plate, the first clamping assembly 1403 clamps the lighter shell, and then the first spacing assembly 1404 is used to drive the first clamping assembly 1403 to move away from each other, so that the distance between two adjacent lighter shells is expanded, so as to facilitate subsequent processing operations. Therefore, after the present invention completes the feeding by the vibration plate, the first spacing assembly 1404 is used to expand the distance between two adjacent lighter shells, so as to facilitate the subsequent processing and assembly of the lighter shell.

[0123] The first drive assembly 1402 includes a horizontal drive assembly and a vertical drive assembly whose driving directions are perpendicular to each other. The horizontal drive assembly and the vertical drive assembly can respectively drive the first clamping assembly 1403 to move horizontally or vertically, so as to clamp the lighter housing and transport it to the next assembly position. The present invention does not limit the specific structure of the horizontal drive assembly and the vertical drive assembly. For example, the following specific structure can be adopted. The horizontal drive assembly includes a drag chain, and the vertical drive assembly includes a motor and a screw rod connected to the drive, and the sleeve is threadedly connected to the screw rod.

[0124] The first clamping assembly 1403 includes a first clamping jaw 1405 and a first connecting frame 1406 fixedly connected to the first clamping jaw 1405 . One end of the first connecting frame 1406 away from the first clamping jaw 1405 is connected to the first spacing assembly 1404 .

[0125] Preferably, the inner surface of the first clamping jaw 1405 is provided with a first clamping groove 1407 recessed into the first clamping jaw 1405, and the surface of the first clamping groove 1407 is arc-shaped. Since the outer surface of the lighter housing has an arc-shaped edge, setting the surface of the first clamping groove 1407 to an arc shape can increase the degree of fit.

[0126] Preferably, five first clamping jaws 1405 are provided and the first clamping jaws 1405 are arranged parallel to each other. In this way, five lighter outer shells can be clamped and assembled at the same time and kept parallel, thereby improving production efficiency.

[0127] The first separation assembly 1404 includes a first mounting plate 1408 fixedly connected to the first driving assembly 1402, at least one first sliding guide rod 1409 fixedly connected to the first mounting plate 1408, a plurality of first separation sliders 1410 slidably connected to the first sliding guide rod 1409, a first linear driving structure 1411 fixedly arranged on one side of the first mounting plate 1408, a first scissor-type telescopic structure 1412 drivingly connected to the first linear driving structure 1411, the first linear driving structure 1411 can drive the first scissor-type telescopic structure 1412 to extend or shorten, and the bottom surface of the first separation slider 1410 is fixedly connected to the first scissor-type telescopic structure 1412. Among them, the first linear driving structure 1411 can adopt the following specific structure, the first linear driving structure 1411 includes a cylinder and an output shaft connected to the cylinder.

[0128] Specifically, the first scissor-type telescopic structure 1412 includes a plurality of articulated units connected in sequence, each articulated unit includes two first articulated arms 1413 that cross each other, the two first articulated arms 1413 in the same articulated unit are centrally hinged, the ends of the first articulated arms 1413 between two adjacent articulated units are hinged, and the first spacing slider 1410 is fixedly connected to the articulation center of the two first articulated arms 1413 in the same articulated unit.

[0129] The first scissor-type telescopic structure 1412 adopts, for example, the scissor-type structure in the invention patent with application number “201520225179.0”. This structure is relatively stable in the telescopic process and can ensure that the distance between each first clamping assembly 1403 is equal after telescopic operation.

[0130] Preferably, four first sliding guide rods 1409 are provided, and the first sliding guide rods 1409 are parallel to each other, so as to ensure the stability of the first spacing sliding block 1410 during the sliding process.

[0131] The first circulating conveying mechanism 1300 includes a first circulating conveying frame 1301 with at least one first processing station 1302 on the side, and a plurality of first moving blocks 1303 are arranged on the first circulating conveying frame 1301, wherein the upper surface of the first moving block 1303 is provided with a plurality of mounting grooves recessed into the first moving block 1303. The lighter housing is connected to the first moving block 1303 through these mounting grooves, so as to move synchronously with the first moving block 1303. The first moving block 1303 is formed into a ring around the first circulating conveying frame 1301, and has a first advancement gap 1304 between the head and the tail, and also includes a first No. 1 advancement assembly 1305 and a first No. 2 advancement assembly 1306 connected to the first circulating conveying frame 1301 for advancing the first moving block 1303 to move, and the first No. 1 advancement assembly 1305 and the first No. 2 advancement assembly 1306 have different advancement directions.

[0132] When in use, the lighter housing to be assembled is transferred to the first moving block 1303. According to the position of the first push gap 1304, the first push assembly 1305 or the first push assembly 1306 pushes the first moving block 1303 to move into the first push gap 1304. At this time, a new first push gap 1304 is generated, and the first push assembly 1305 or the first push assembly 1306 pushes the first moving block 1303 to move into the first push gap 1304 again, so that the first moving block 1303 drives the lighter housing to be assembled to move and pass through the first processing station 1302 in sequence to achieve processing and assembly. Therefore, the first moving block 1303 for conveying products of the present invention is formed around a ring, and the products are circulated along the first circulating conveyor frame 1301 by pushing the moving block, thereby solving the problem that the above-mentioned conveyor line is long and requires a larger space.

[0133] Preferably, the first propulsion assembly 1305 is a transverse propulsion assembly, the first second propulsion assembly 1306 is a longitudinal propulsion assembly, and the propulsion directions of the first first propulsion assembly 1305 and the first second propulsion assembly 1306 are perpendicular to each other. In this way, the first moving block 1303 can be ensured to move in two directions that do not interfere with each other, and the movement process and the moving position of the first moving block 1303 become simple and controllable.

[0134] The first propulsion assembly 1305 includes a first propulsion cylinder 1307 fixedly mounted on the first circulation conveyor frame 1301 , and a first transverse propulsion block 1308 is fixedly connected to the output shaft of the first propulsion cylinder 1307 .

[0135] The first and second propulsion components 1306 may also adopt a specific structure similar to that of the first and first propulsion components 1305, but in order to ensure the accuracy during the longitudinal propulsion process, preferably, the first and second propulsion components 1306 include a first propulsion motor 1309 fixedly mounted on the first circulation conveyor frame 1301, a first propulsion screw 1310 drivingly connected to the first propulsion motor 1309, a first longitudinal propulsion block 1311 being threadedly connected to the first propulsion screw 1310, and rotating the first propulsion screw 1310 can move the first longitudinal propulsion block 1311 along the axis direction of the first propulsion screw 1310. Further preferably, the first propulsion motor 1309 is a servo motor.

[0136] The first circulating conveyor frame 1301 is provided with a first clearance groove 1312, and one end of the first longitudinal propulsion block 1311 extends to the first clearance groove 1312. The first longitudinal propulsion block 1311 can be moved so that the first longitudinal propulsion block 1311 passes through the first clearance groove 1312 and is pressed onto the first moving block 1303. In this way, the first longitudinal propulsion block 1311 can be prevented from interfering with the edge of the first circulating conveyor frame 1301 when performing the propulsion action.

[0137] There is only one first pushing notch 1304 , and the first moving block 1303 is movably connected to the first circulating conveying frame 1301 , and two adjacent first moving blocks 1303 fit together.

[0138] Preferably, the shapes and sizes of each first moving block 1303 are the same, and the shapes and sizes of the first moving block 1303 and the first pushing notch 1304 are the same. The width of each first moving block 1303 is 40 mm, and the length is 200 mm, so the single pushing distance of the first No. 1 pushing assembly 1305 is 40 mm, and the single pushing distance of the first No. 2 pushing assembly 1306 is 200 mm. In this way, it is ensured that each time the first moving block 1303 is pushed, it moves one body position horizontally or vertically. Thus, the orderliness and stability of the moving and conveying process are ensured.

[0245] The working principle of the second workstation is as follows:

[0246] Straw feeding principle: the straws 2 are sorted by the second straw feeding vibration plate 2330, and the sorted straws 2 enter the second straw feeding channel 2320 of the second straw feeding track 2310. The second straw feeding channel 2320 gradually tilts downward from the outer end to the inner end and moves the inner end of the straw 2 by the straight vibrator. The second straw positioner 2200 rotates clockwise with the second assembly turntable 2100. When the straw suspension groove 210 of the second straw positioner 2200 and the second straw feeding channel 2320 are located in the same axial direction, a straw 2 in the second straw feeding channel 2320 enters the straw suspension groove 210, thereby completing the feeding.

[0247] Zinc sleeve feeding and assembly principle: a number of zinc sleeves 1 are sorted by the second zinc sleeve vibration plate 2510 and transported to a second zinc sleeve transfer slot 2540 of the second feeding plate 2520 through the second zinc sleeve sorting tube 2560. After the second feeding plate 2520 rotates, it is located between the second top shaft 2610 of the second zinc sleeve lifting assembly mechanism 2600 and the suction tube 2, that is, the second feeding plate 2520 stops rotating after being located in the feeding area. At this time, the zinc sleeve 1 can be lifted by the second top shaft 2610 and thus vertically upwardly separated from the second zinc sleeve transfer slot 2540 of the second feeding plate 2520.

[0248] Working principle of the second zinc sleeve lifting assembly mechanism 2600: the second push rod mounting ring 2630 rotates synchronously with the second rotating frame 2120, and the second pulley 2642 at the bottom of the second top shaft 2610 slides on the second annular slide rail 2641. When the second top shaft 2610 passes through the second lifting boss 2643, the second top shaft 2610 moves axially upward, and the lower end of the straw enters into the second straw insertion hole 2620 through the second straw through-hole 2614 of the second back nozzle 2613, and the zinc sleeve is lifted upward by the second back nozzle 2613, thereby completing the assembly of the zinc sleeve 1 and the straw 2 to form a straw zinc sleeve set 3.

[0249] After the zinc sleeve set 3 of the straw is assembled, the zinc sleeve 1 is positioned by the second zinc sleeve suspension bayonet 2712 of the second zinc sleeve suspension rod 2711 extending radially to prevent the zinc sleeve 1 from falling off the straw 2 downward.

[0250] When the zinc straw set 3 rotates to approach the second material receiving seat 2431, the second vertical push rod 2423 of the second self-resetting tube pusher 2420 contacts the second discharge top plate 2410, causing the second vertical push rod 2423 to drop vertically, and the dropped second vertical push rod 2423 causes the second horizontal push rod 2422 to push outward, thereby pushing the zinc straw set 3 on the second tube seat 2220 into the second material receiving channel 2432 of the second material receiving seat 2431, and enters the second discharge spacing mechanism 2800 through the discharge channel 491.

[0251] The working principle of the second discharging and spacing mechanism 2800 is as follows: after the second bayonet 2840 of the second spacing material seat 2830 is aligned with the second feeding channel 2491 of the second feeder 2490, the zinc straw set 3 on the second feeding channel 2491 enters the second bayonet 2840, and the second spacing material seat 2830 rotates the second conveyor belt 2821 after receiving, thereby replacing the next second spacing material seat 2830 to receive the zinc straw set 3, and the second spacing material seat 2830 that has completed receiving moves to the side of the second spacing stopper 2850 to cooperate with it, so that the second bayonet 2840 is connected with the second No. 2 clamp extending into the slot 2851, and the 5 groups of zinc straw sets 3 after spacing are completed are taken away at one time by the second discharging assembly robot 2900.

[0252] When the second discharging assembly robot 2900 is working, the second jaw driver mounting seat 2920 adjusts its position through the second transverse movement component 2930 and the second vertical movement component 2940, so that the second jaw 2960 can be in the required position, and then the second jaw 2960 is controlled to be grasped and released through the second jaw driver 2950. The first zinc sleeve clamping grooves 971 on both sides are used to clamp the zinc sleeve 1 to prevent it from radially detaching from the second jaw 2960, and the two second zinc sleeve clamping blocks 2961 are used to prevent the zinc sleeve 1 from axially detaching from the second jaw 2960 downward.

The third vibration disk 323 is fixedly mounted on the third base 325. The end of the third material guide trough 324 away from the third vibration disk 323 is connected to the third assembly assembly 322. The third assembly assembly 322 includes a third assembly head 326 located above the third rotating mechanism 31. The third assembly head 326 is also driven and connected with a third horizontal drive mechanism 327 and a third vertical drive mechanism 328. The third horizontal drive mechanism 327 and the third vertical drive mechanism 328 drive the third assembly head 326 to move closer to or away from the third fixture 3100. The third horizontal drive mechanism 327 and the third vertical drive mechanism 328 can select the specific structures commonly used in the prior art for realizing horizontal drive and vertical drive. For example, the third horizontal drive mechanism 327 can be realized by the cooperation of a drag chain and a slider rail, and the third vertical drive mechanism 328 can be realized by the cooperation of a cylinder and a slider rail.

[0266] The working principle of the third workstation is as follows: when in use, the lighter housing with the flat gasket, constant flow valve and other parts to be assembled is clamped in the third fixture 3100, the driving motor drives the third rotating disk 312 to rotate, thereby driving the third fixture 3100 to arrive at the bottom of the third assembly head 326 of different third assembly stations 32 in sequence, the third vibration disk 323 conveys the parts to be assembled to the third assembly head 326 through the third guide groove 324, and the third horizontal driving mechanism 327 and the third vertical driving mechanism 328 drive the third assembly head 326 to approach the third fixture 3100 to complete the assembly with the lighter housing on the third fixture 3100.

The fourth transfer manipulator is similar in structure to the second discharge assembly manipulator 2900, except for the clamping structure.

[0268] When in use, the lighter assembly to be installed with the gas valve is placed on the fourth conveyor line 42, and is transported to the bottom of the fourth gas valve feeding mechanism 43 through the fourth conveyor line 42. The gas valve is transported into the lighter assembly through the fourth gas valve feeding mechanism 43, and then transported to the bottom of the fourth gas valve locking mechanism 4100 by the fourth conveyor line 42, and the gas valve is locked by the fourth gas valve locking mechanism 4100. Therefore, the present invention places the lighter assembly to be installed with the gas valve on the fourth conveyor line 42, and sequentially passes through the fourth gas valve feeding mechanism 43 and the fourth gas valve locking mechanism 4100 to realize automatic installation of the gas valve, thereby improving the degree of automation of the assembly process.

[0269] The fourth gas valve feeding mechanism 43 includes a fourth material feeding component 431 and a fourth material guiding component 432 which are interconnected. The fourth material guiding component 432 is located directly above the fourth conveying line 42. The fourth material feeding component 431 includes a fourth base 433 and a fourth vibration plate 434 fixedly connected to the fourth base 433. At least one fourth material feeding pipe 435 is connected to the fourth vibration plate 434.

[0270] When in use, the fourth vibration disk 434 is started, and the air valves in the fourth vibration disk 434 are transported to the fourth material guide groove 437 through the fourth material delivery pipe 435, and the air valves are transported one by one to the lighter components through the fourth material guide groove 437.

[0271] Preferably, the fourth material guiding groove 437 is connected to the fourth material conveying pipe 435 in a one-to-one correspondence, so that multiple lighter components can be assembled at the same time, thereby improving assembly efficiency.

[0272] The fourth air valve locking mechanism 4100 includes a fourth locking mounting frame 4101 fixedly connected to the fourth frame 41, and the fourth locking mounting frame 4101 is provided with a fourth driving mechanism 4102 and a fourth locking assembly 4103. The fourth driving mechanism 4102 is located above the fourth locking assembly 4103, and also includes a fourth elastic buffer assembly 4104 located between the fourth driving mechanism 4102 and the fourth locking assembly 4103. The fourth driving mechanism 4102 is driven and connected to the fourth locking assembly 4103 via the fourth elastic buffer assembly 4104.

[0273] When in use, the lighter with the gas valve to be locked is transported to the bottom of the fourth locking assembly 4103 through the conveying line, and the fourth driving mechanism 4102 drives the fourth elastic buffer assembly 4104 so that the fourth locking assembly 4103 is pressed down onto the lighter with the gas valve to be locked, thereby locking the lighter gas valve. When the downward pressure is too large, the fourth elastic buffer assembly 4104 will be compressed, thereby preventing the lighter from being crushed. The present invention is provided with a fourth elastic buffer assembly 4104 in the fourth gas valve locking mechanism 4100, and the fourth elastic buffer assembly 4104 prevents the fourth gas valve locking mechanism 4100 from causing damage to the lighter.

[0274] Preferably, a positioning structure is also provided on the fourth locking mounting frame 4101, and the positioning structure includes a positioning claw with a groove and a linear drive connected to the positioning claw. The linear drive is fixedly connected to the fourth locking mounting frame 4101, and the linear drive drives the positioning claw to move the positioning claw to directly below the fourth locking assembly 4103.

[0275] Before locking, the positioning claws can be used to locate the position of the lighter whose gas valve is to be locked, thereby ensuring the accuracy of the pressing position.

[0276] The fourth driving mechanism 4102 includes a fourth mounting plate 4105 fixedly connected to the fourth locking mounting frame 4101 and a fourth cylinder 4106 disposed on the fourth mounting plate 4105 , and a fourth output shaft 4107 is connected to the fourth cylinder 4106 .

[0277] The fourth elastic buffer assembly 4104 includes a fourth pressure plate 4108 which can move up and down in the vertical direction. One end of the fourth elastic member 4109 is pressed on the fourth output shaft 4107, and the other end is pressed on the fourth pressure plate 4108. The fourth pressure plate 4108 is pressed on the fourth locking assembly 4103.

[0278] Specifically, the fourth elastic member 4109 is a spring, which is sleeved outside the fourth output shaft 4107 and one end of the fourth output shaft 4107 passes through the fourth pressing plate 4108. The fourth output shaft 4107 has a circle of annular flange, and the spring is pressed on the annular flange.

[0279] When in use, the fourth cylinder 4106 is activated to drive the fourth output shaft 4107 to extend downward, thereby compressing the spring. After being compressed, the spring applies pressure to the fourth pressure plate 4108, thereby transmitting the pressure to the fourth locking assembly 4103. When the reaction force fed back to the fourth locking assembly 4103 by the lighter is too large, the spring will contract, causing the fourth pressure plate 4108 to move upward, thereby achieving a buffering effect.

[0280] Preferably, the axis center line of the spring coincides with the axis center line of the fourth output shaft 4107. This ensures stable force transmission.

[0281] Preferably, a plurality of fourth sliding sleeves 4110 are fixedly connected to the fourth pressing plate 4108, and the fourth sliding sleeves 4110 are slidably connected to the fourth guide rods 4111, and the fourth sliding sleeves 4110 and the fourth guide rods 4111 are arranged one-to-one, and the fourth guide rods 4111 are fixedly connected to the fourth mounting plate 4105.

[0283] There are a plurality of fourth locking heads 4113, and every two fourth locking heads 4113 are parallel to each other, and the spacing between two adjacent fourth locking heads 4113 is equal. In this way, multiple lighter gas valves can be locked at one time, thereby improving assembly efficiency.

[0284] A fourth clearance space 4116 is further provided between the fourth locking platform 4112 and the fourth elastic buffer assembly 4104. At least one fourth drive motor 4114 is located in the fourth clearance space 4116 and connected to the fourth locking platform 4112. The fourth drive motor 4114 is drivingly connected to the fourth locking head 4113 via a fourth transmission belt 4115. In this way, the fourth locking head 4113 can not only apply pressure, but also rotate, further expanding the applicable scenarios of the locking structure.

[0285] The working principle of the fourth workstation is: when in use, the lighters assembled at the third workstation 3 are transferred to the fourth workstation 4 by the fourth transfer manipulator, and are transported to the bottom of the fourth air valve feeding mechanism 43 through the fourth conveying line 42. At this time, the fourth vibration plate 434 is started, and the air valves in the fourth vibration plate 434 are transported to the fourth guide groove 437 through the fourth conveying pipe 435. The air valves are transported one by one to the lighter assembly through the fourth guide groove 437, and then transported to the bottom of the fourth locking assembly 4103 by the fourth conveying line 42. The position of the lighter to be locked by the air valve is first positioned with the positioning claw to ensure the accuracy of the clamping position, and at the same time, the displacement of the lighter to be locked by the air valve during the clamping process can be prevented. The fourth cylinder 4106 is started to drive the fourth output shaft 4107 to extend downward, thereby compressing the spring. After the spring is compressed, pressure is applied to the fourth pressure plate 4108, thereby transmitting the pressure to the fourth locking platform 4112, so that the fourth locking head 4113 is pressed downward. When the reaction force fed back by the lighter to the fourth locking head 4113 is too large, the spring will shrink, causing the fourth pressing plate 4108 to move upward, thereby achieving a buffering effect. Therefore, the present invention places the lighter assembly to be installed with the gas valve on the fourth conveyor line 42, and sequentially passes through the fourth gas valve feeding mechanism 43 and the fourth gas valve locking mechanism 4100 to achieve automatic installation of the gas valve, thereby improving the degree of automation of the assembly process.

[0360] In this embodiment, further, when the seventh wind shield stop block 716 clamps the wind shield, the seventh wind shield anti-displacement limiting structure 720 further prevents the wind shield from shaking left and right, thereby preventing one side of the wind shield from being disconnected from the seventh wind shield clamp block 713 and causing it to fall.

[0361] The seventh wind shield anti-displacement limiting structure 720 includes a seventh limiting slot 721 vertically arranged on the seventh wind shield stop block 716 on one side of the seventh wind shield clamping block 713 .

[0362] In this embodiment, the front end of the wind hood has a protrusion with a curved cross-section. When the seventh wind hood stop block 716 abuts against the wind hood, the protrusion extends into the seventh limit slot 721. Therefore, the part extending into the seventh limit slot 721 is restricted by the seventh limit slot 721 and cannot move left or right. Even if the wind hood cannot move left or right, it can further prevent the wind hood from falling off.

[0363] Seventh anti-injury inclined surfaces 722 are disposed on both sides of the seventh limiting slot 721 .

[0364] In this embodiment, in order to prevent the seventh wind shield abutment block 716 from wearing out the end corner of the seventh limiting slot 721 or damaging the wind shield when abutting against the wind shield, this part is provided as an inclined anti-injury inclined surface.

[0365] A plurality of seventh grippers 712 are arranged in a straight line on a seventh gripper mounting seat 711 , and a seventh wind shield layout component 723 is provided on one side of the seventh assembly robot 710 .

[0366] In this embodiment, the seventh wind hood layout component 723 arranges several wind hoods in a straight line in sequence. When several seventh claws 712 grab a row of wind hoods at a time, the seventh wind hood layout component 723 works to make the following several wind hoods form a row and move them to the grabbed position.

[0367] On the one hand, mechanical automation is adopted to discharge, grab and install the wind hoods. On the other hand, multiple wind hoods can be grabbed at one time to improve work efficiency.

[0368] The seventh wind hood layout component 723 includes a seventh wind hood sorting plate 724, on which are provided seventh sorting slots 725 equal in number to the seventh claws 712, one end of the seventh wind hood sorting plate 724 is provided with a seventh vibration plate 727 connected to the seventh sorting slots 725, and the other end of the seventh wind hood sorting plate 724 is provided with a seventh separator 726 for receiving a wind hood in each seventh sorting slot 725.

[0369] In this embodiment, the seventh vibration plate 727 vibrates continuously, and under the action of vibration, a number of wind hoods gradually move to the seventh wind hood sorting plate 724, and enter into a plurality of seventh sorting slots 725 to be arranged in a team. The wind hood at the front end of the seventh sorting slot 725 will eventually move into the seventh separator 726. The wind hoods entering the seventh separator 726 are staggered with the wind hoods in the original team, so as to facilitate the seventh claw hand 712 to grab the wind hoods entering the seventh separator 726.

[0370] The seventh separator 726 includes a seventh partition plate 728, on which are provided seventh partition material taking slots 729 whose number is equal to the seventh sorting slots 725 and the seventh partition material taking slots 729 correspond one-to-one to the seventh sorting slots 725, and a seventh horizontal pushing assembly 731 is provided between the seventh partition plate 728 and the seventh base 730, which can cause the seventh partition material taking slots 729 to be misaligned with the seventh sorting slots 725.

[0371] In this embodiment, when the wind hood is not clamped, the seventh partition material trough 729 is connected to the corresponding seventh sorting trough 725. At this time, the wind hood at the front end of the seventh sorting trough 725 is moved into the seventh partition material trough 729 under the operation of the seventh vibration plate 727. When each seventh partition material trough 729 has a wind hood, the seventh horizontal push assembly 731 pushes the seventh partition plate 728 to move horizontally, so that the seventh partition material trough 729 and the corresponding seventh sorting trough 725 are staggered. Even if the wind hood entering the seventh partition material trough 729 is staggered with the wind hood in the original team, it is convenient for the seventh claw hand 712 to grab the wind hood entering the seventh partition material trough 729.

[0372] Preferably, the seventh wind shield sorting plate 724 is gradually tilted downward from one end to the other end, and a seventh direct vibrator 732 is provided at the bottom of the seventh wind shield sorting plate 724. In this embodiment, the wind shield is moved to the top of the seventh wind shield sorting plate 724 under the action of the seventh vibration disk 727, and the wind shield located at the top of the seventh wind shield sorting plate 724 is gradually moved downward under the continuous action of vibration and the action of the inclined guide. In addition, since the seventh wind shield sorting plate 724 is far away from the seventh vibration disk 727, the vibration effect cannot be transmitted, and the wind shield on the seventh wind shield sorting plate 724 is vibrated and gradually moved downward by the seventh direct vibrator 732 vibrating at the same frequency and direction as the seventh vibration disk 727.

[0373] Preferably, the seventh horizontal push assembly 731 includes a seventh horizontal push linear driver 734 disposed on a seventh horizontal push linear driver fixing frame 733, and a driving end of the seventh horizontal push linear driver 734 is connected to the seventh partition plate 728. In this embodiment, when each seventh partition material taking trough 729 has an air cover, the seventh horizontal push linear driver 734 drives the seventh partition plate 728 to move horizontally, so that the air cover entering the seventh partition material taking trough 729 is misaligned with the air cover in the original team.

[0374] Preferably, the seventh vibration disk 727 is a five-track vibration disk, and the seventh wind cover sorting plate 724 is provided with five seventh sorting grooves 725 which are parallel to each other, and the five seventh sorting grooves 725 are connected to the five-track vibration disk.

[0375] Preferably, one side of each seventh sorting slot 725 is provided with a seventh clearance slot 736 located at the end of the seventh wind shield sorting plate 724, which is convenient for the seventh wind shield stopper 716 to extend into. After the wind shields entering the seventh partitioning material taking slot 729 are misplaced with the wind shields in the original team, the seventh claw hand 712 needs to grab the wind shields. Due to the existence of the seventh wind shield stopper 716, during the clamping process, the seventh wind shield stopper 716 will move to the top of the seventh wind shield sorting plate 724 and gradually approach the seventh wind shield sorting plate 724. Therefore, in order to prevent the seventh wind shield stopper 716 from colliding with the seventh wind shield sorting plate 724, during the clamping process, the seventh wind shield stopper 716 will move and extend into the seventh clearance slot 736.

[0376] like Figure 6 As shown, in this embodiment, a slot 71 is provided on the lighter, and a buckle 72 is provided on the inner wall of the air cover. When the air cover is installed on the lighter, the buckle 72 will be inserted into the slot 71 so that the air cover and the lighter are connected together.

[0377] The working principle of the present invention is as follows: the seventh straight vibrator 732 and the seventh vibration plate 727 move the wind hood to the top of the seventh wind hood sorting plate 724 and enter into a plurality of seventh sorting slots 725, and under the inclined guiding action, the wind hood located at the top of the seventh wind hood sorting plate 724 gradually moves downward and is arranged in a queue in the seventh sorting slots 725. When each seventh partition material trough 729 has an air hood, the seventh horizontal push linear driver 734 drives the seventh partition plate 728 to move horizontally, so that the air hood entering the seventh partition material trough 729 is offset from the air hood in the original team, and then the seventh assembly robot 710 moves to the top of the seventh partition material trough 729 and makes the seventh claw hand 712 close to the air hood and moves the air hood relative to the seventh claw hand 712 to the inside of the seventh claw hand 712 and abuts against the two seventh air hood clamping blocks 713, so that the air hood is located and clamped between the two seventh air hood clamping blocks 713, and the seventh clamping cylinder 718 works to make the seventh clamping slider 719 move with the seventh air hood abutting block 716 towards the air hood and finally clamp the air hood, and finally install it after clamping the air hood.

[0378] The structures of the wind shield assembly mechanism 72, the steel wheel assembly mechanism 73 and the pressure plate assembly mechanism 74 are similar, and the difference lies in the claw hands.

[0382] In this embodiment, the quality of the flint of the lighter is detected by rotating the eighth friction wheel 812 to move the flint on the lighter and observing whether the flint generates sparks by friction. In this process, the eighth linear motion mechanism 814 can drive the eighth friction wheel mounting frame 811 to move back and forth in the horizontal direction. Under the operation of the eighth linear motion mechanism 814, the eighth friction wheel 812 gradually approaches the flint and contacts the flint. The eighth friction wheel 812 is provided with a gear ring that can mesh with the flint. The eighth friction wheel rotation drive mechanism 813 drives the eighth friction wheel 812 to rotate. The rotating eighth friction wheel 812 drives the flint to rotate and observes whether the flint generates sparks, thereby completing the detection of the quality of the flint. The flints on multiple lighters can be detected at the same time, thereby improving the detection efficiency.

[0383] The eighth friction wheel rotation driving mechanism 813 includes an eighth friction wheel rotation shaft 815 disposed on an eighth friction wheel mounting frame 811 , and a plurality of eighth friction wheels 812 are mounted on the eighth friction wheel rotation shaft 815 , which is connected to an eighth friction wheel rotation driver 816 .

[0384] In this embodiment, each eighth friction wheel 812 has the same size and is arranged on the same axis, so the outer ring of each eighth friction wheel 812 is on the same plane. When detecting multiple lighters at the same time, it is only necessary to place several lighters side by side and arrange them in a straight line. When the eighth friction wheel 812 is in contact with the flint, the eighth friction wheel rotation driver 816 drives the eighth friction wheel rotation shaft 815 to rotate, thereby driving several eighth friction wheels 812 to rotate at the same time and performing quality inspection on multiple flints at the same time.

[0385] The eighth linear motion mechanism 814 includes an eighth linear driver 817 disposed on one side of the eighth friction wheel mounting frame 811 , and an eighth linear motion guide assembly 818 is disposed on the other side of the eighth friction wheel mounting frame 811 .

[0386] In this embodiment, the eighth linear drive 817 is used to drive the eighth friction wheel mounting frame 811 to perform reciprocating movement in a straight line. Since the eighth friction wheel mounting frame 811 has a certain length and mass, in order to stabilize the movement of the eighth friction wheel mounting frame 811, the eighth linear motion guide assembly 818 further guides the movement of the eighth friction wheel mounting frame 811 in the straight direction, and is used to support the weight of the eighth friction wheel mounting frame 811 to prevent tilting caused by long-term use.

[0388] In this embodiment, one end of the eighth screw rod 820 is fixedly connected to the output shaft of the eighth screw motor 819, and the other end is rotatably connected to the eighth frame 810 through a rotating bearing. Through the connection method of the screw rod and the thread sleeve, the moving distance of the eighth friction wheel mounting frame 811 is more precise and stable, and the slowing down of the moving speed allows the eighth friction wheel 812 to slowly fit with the flint, preventing the flint from hitting due to excessive moving speed or improper distance control.

[0389] The eighth linear motion guide assembly 818 includes an eighth guide frame 822 and an eighth guide slider 823, between which at least one eighth guide shaft 824 is provided, and the eighth guide slider 823 is fixed on the eighth guide slider fixing plate 825 above the other side of the eighth friction wheel mounting frame 811.

The eighth guide shaft 824 is used to further guide the moving direction of the eighth friction wheel mounting frame 811. In addition, the eighth guide slider 823 and the eighth guide shaft 824 are connected by a rotating bearing, and the rotating bearing is rotatably arranged in the eighth guide slider 823, and the eighth guide shaft 824 slides through the rotating bearing, so as to reduce the friction between the eighth guide slider 823 and the eighth guide shaft 824.

[0391] The cross section of the eighth friction wheel rotating shaft 815 is D-shaped. The eighth friction wheels 812 are sleeved on and adapted to the eighth friction wheel rotating shaft 815 . An eighth friction wheel axial positioning structure 826 is provided between the eighth friction wheel 812 and the eighth friction wheel rotating shaft 815 .

[0392] In this embodiment, the cross section of the eighth friction wheel rotating shaft 815 is D-shaped, and the eighth friction wheel 812 can only slide on the eighth friction wheel rotating shaft 815 and rotate with the eighth friction wheel rotating shaft 815. After the eighth friction wheel 812 is moved, the friction wheel is positioned by the eighth friction wheel axial positioning structure 826.

[0398] Preferably, the eighth positioning sleeve 828 is also fixed on the eighth friction wheel rotating shaft 815 by fixing bolts. The eighth positioning sleeve 828 can be replaced with different lengths.

[0399] An eighth visual inspection unit mounting frame 830 is provided on the other side of the eighth frame 810 . A plurality of eighth visual inspection units 831 are provided on the eighth visual inspection unit mounting frame 830 . The number of the eighth visual inspection units 831 is equal to the number of the eighth friction wheels 812 .

[0400] In this embodiment, during the process of detecting the quality of the flint, each eighth visual inspection unit 831 detects whether the flint produces sparks during the rotation process by video recording or visual monitoring, so as to determine whether the quality of the flint is qualified.

[0401] The eighth visual detection unit mounting frame 830 is connected to an eighth positioning structure 832 which can drive the eighth visual detection unit mounting frame 830 to approach or move away from the eighth frame 810 .

[0402] In this embodiment, the distance between the eighth visual detection unit 831 and the detection position, that is, the position of the lighter, can be adjusted through the eighth adjustment structure 832, so that the detection process can be observed more clearly.

[0405] The rotation of the eighth visual detection unit 831 can further adjust the observation angle of the eighth visual detection unit 831 to observe the eighth friction wheel 812, thereby further improving the observation clarity and accuracy.

[0406] More specifically, the finished lighter delivery mechanism 9 includes a ninth discharging platform 910, on which a ninth empty box conveying channel 911 and a ninth full box conveying channel 912 are provided, and the ninth empty box conveying channel 911 and the ninth full box conveying channel 912 are respectively provided with a ninth empty box conveying drive assembly 913 and a ninth full box conveying drive assembly 914, the side of the box outlet end of the ninth empty box conveying channel 911 is connected to the side of the box inlet end of the ninth full box conveying channel 912, a ninth empty box pushing assembly 915 is provided between the box outlet end of the ninth empty box conveying channel 911 and the box inlet end of the ninth full box conveying channel 912, and a ninth jaw spacing variable manipulator 916 is also provided on the ninth discharging platform 910.

[0407] The empty box is pushed to the discharge placement position by the ninth empty box conveying drive assembly 913, and then the lighter is grasped by the ninth clamping jaw spacing variable manipulator 916 and moved into the empty box, and the empty box is filled with a plurality of lighters in sequence by the ninth clamping jaw spacing variable manipulator 916. The empty box is in the ninth empty box conveying channel 911 and conveyed by the ninth empty box conveying drive assembly 913. When the empty box moves to the designated position, the empty box is pushed into the ninth full box conveying channel 912 by the ninth empty box pushing assembly 915, and the lighter is loaded at this time. After slow fire, the full box is moved and conveyed out of the discharge table 10 by the ninth full box conveying drive assembly 914. When the full box is pushed into the ninth full box conveying channel 912, the ninth empty box pushing assembly 915 continues to work to move the next empty box to the discharge placement position.

[0408] In this process, the ninth jaw spacing variable manipulator 916 coordinates with various conveying drive components to complete sustainable discharge steps, and the entire process is automated and controllable.

[0409] The ninth empty box conveying passage 911 and the ninth full box conveying passage 912 are parallel to each other.

[0410] When a full box is conveyed, the next empty box is conveyed, and the transportation status of the two conveying channels 12 can be observed intuitively, and the discharge status can be calculated intuitively. In addition, since the box conveying channel 11 and the ninth full box conveying channel 912 are parallel to each other, the connection between the ninth empty box conveying channel 911 and the ninth full box conveying channel 912 can be in a straight line. The empty box only needs to enter the ninth full box conveying channel 912 along a straight line from the ninth empty box conveying channel 911 to be loaded. The route is short and does not require changing direction, which prevents jamming.

[0411] Ninth side stop bars 917 are disposed on both sides of the ninth empty box conveying channel 911 and the ninth full box conveying channel 912 and the ninth side stop bars 917 are shared. A ninth front stop bar 918 is disposed at the box inlet end of the ninth empty box conveying channel 911 .

[0412] The ninth side bar 917 is located between the ninth empty box conveying channel 911 and the ninth full box conveying channel 912. On the one hand, it is used to separate the ninth empty box conveying channel 911 and the ninth full box conveying channel 912. On the other hand, it greatly reduces the distance between the ninth empty box conveying channel 911 and the ninth full box conveying channel 912. That is, the length of the connecting port between the ninth empty box conveying channel 911 and the ninth full box conveying channel 912 is shorter, which makes it easier to transport boxes from the ninth empty box conveying channel 911 to the ninth full box conveying channel 912.

[0413] A ninth box in-and-out platform 919 is provided at the box inlet end of the ninth empty box conveying channel 911 and the box outlet end of the ninth full box conveying channel 912 .

[0414] The ninth box in and out platform 919 is used to place empty boxes and convey them into the ninth empty box conveying channel 911, and is also used to output full boxes. The full boxes pass through the ninth full box conveying channel 912 to the ninth box in and out platform 919 for subsequent packaging and transportation of the full boxes.

[0415] The ninth empty box conveying driving assembly 913 comprises a ninth belt conveyor 920 . The ninth belt conveyor 920 is connected to the ninth empty box conveying passage 911 . Ninth limit levers 921 are provided on both sides of the conveying belt of the ninth belt conveyor 920 .

[0416] A plurality of empty boxes are placed on the conveyor belt of the ninth belt conveyor 920. As the ninth belt conveyor 920 works, the empty boxes are transported into the ninth empty box conveying passage 911, and the empty boxes in the ninth empty box conveying passage 911 are pushed forward by the empty boxes behind. The limit stoppers 21 on both sides are used to determine the conveying direction of the empty boxes to prevent the empty boxes from being stuck at the entrance of the ninth empty box conveying passage 911.

[0417] The ninth full box conveying drive assembly 914 includes a ninth box pushing claw 922 arranged on the box input end of the ninth full box conveying channel 912, the ninth box pushing claw 922 is inserted into the ninth box pushing claw travel groove 923 of the discharge platform 10, and the lower end of the ninth box pushing claw 922 is connected to the ninth box pushing claw linear driver 924 at the bottom of the discharge platform 10.

[0418] When the empty box is pushed into the ninth full box conveying channel 912, the ninth box pushing claw 922 is located at one end of the empty box. After the empty box is filled with lighters, the ninth box pushing claw 922 slides in the ninth box pushing claw travel groove 923 under the operation of the ninth box pushing claw linear driver 924, and pushes the full box forward while sliding, so that space is reserved at the box entrance end of the ninth full box conveying channel 912 for placing the next empty box.

[0419] The ninth empty box pushing component 915 includes a ninth box pushing block 925 , and the ninth box pushing block 925 is connected to a ninth box pushing block linear driver 926 .

[0420] When the empty box is pushed and moved to the box inlet end of the ninth full box conveying channel 912 , the ninth box pushing block linear driver 926 operates to move the ninth box pushing block 925 and push the empty box to move into the ninth full box conveying channel 912 .

[0421] The ninth variable-distance gripper robot 916 includes a ninth XYZ three-axis robot 927 disposed on the discharge platform 10 , and the ninth XYZ three-axis robot 927 is connected to a ninth variable-distance mechanical gripper assembly 928 .

[0422] The ninth jaw spacing variable manipulator 916 is an XYZ three-axis manipulator, that is, it can move arbitrarily in the horizontal direction and the vertical direction in the track, and is adjusted according to the different positions of the lighter and the different positions of the socket on the box.

[0423] In addition, during the process of placing lighters, the lighters are placed side by side at the pickup area. According to the distance between adjacent lighters, the ninth variable-distance mechanical clamp assembly 928 can also adjust and change the distance between adjacent clamps.

[0424] During the picking and placing process, the position is adjusted and the lighters are grabbed and placed through mechanical automation.

[0425] The ninth variable-pitch mechanical gripper assembly 928 includes a ninth air gripper worktable 929, on which are disposed a plurality of ninth air grippers 530 located in the same straight line, the ninth air grippers 530 being fixed on a ninth air gripper seat 931, and a plurality of ninth air gripper seats 931 being connected via a ninth cross-telescopic structure 932, the ninth air gripper worktable 929 being provided with three ninth guide rods 933 parallel to the bottom surface, the ninth guide rods 933 being connected to the ninth cross-telescopic structure 932, a ninth variable-pitch linear drive 934 being provided at one end of the ninth air gripper worktable 929, and the ninth variable-pitch linear drive 934 being connected to the ninth cross-telescopic structure 932.

[0426] In the process of adjusting the spacing between adjacent air grippers, the output shaft of the linear drive 34 extends outward or moves inward to pull or push the ninth cross-telescopic structure 932. The ninth cross-telescopic structure 932 is arranged in a grid shape and is connected by a number of rotating rods that are rotated in sequence with each other. During adjustment, the ninth air gripper seat 931 moves on the ninth guide rod 933, and the ninth guide rod 933 provides support for the ninth air gripper seat 931.

[0427] The number of ninth lighter sockets 936 on the same row of the ninth lighter base box 935 on the ninth empty box conveying channel 911 is at least twice the number of ninth air grippers 530, and the number of ninth lighter sockets 936 on the same row of the ninth lighter base box 935 is in a multiple relationship with the number of ninth air grippers 530, ensuring that all air grippers can be used each time a lighter is grabbed, thereby improving work efficiency.

[0428] The working principle of the lighter delivery mechanism is as follows: the ninth belt conveyor 920 works to make its conveyor belt carry out cyclic transmission, a number of empty boxes are placed on the conveyor belt and are moved forward driven by the conveyor belt and enter the ninth empty box conveying channel 911. As the conveyor belt continues to drive, the empty box continues to move against the empty box in front, so that the empty box located in the ninth empty box conveying channel 911 moves to the box inlet end of the ninth full box conveying channel 912, and then the ninth box pushing block linear driver 926 works to move the ninth box pushing block 925 and push the empty box to move into the ninth full box conveying channel 912. At this time, the empty box is located at the placement position of the lighter. According to the distance between adjacent lighters, the linear drive 34 operates to extend its output axis outward or move inward, thereby pulling or pushing the ninth cross telescopic structure 932 to change the spacing between adjacent ninth air claws 530. Then, the lighter is clamped and released through the ventilation and deflation of the ninth air claws 530, and the ninth XYZ three-axis manipulator 927 is moved in the xyz direction to finally insert the lighter into the empty box.

[0429] When the empty box is filled with lighters, the ninth box pushing claw 922 slides in the ninth box pushing claw travel groove 923 under the operation of the ninth box pushing claw linear driver 924, and pushes the full box forward while sliding, so that space is reserved at the box inlet end of the ninth full box conveying channel 912 for the next empty box.

[0430] The working principle of the present invention is as follows: the assembly body, the bottom cover and the outer shell assembly are assembled at the first workstation 1, and are transported to the third workstation 3 after the assembly is completed. At the third workstation 3, the zinc sleeve straw group, the flat gasket and the constant flow valve of the lighter are assembled. The assembly of the zinc sleeve straw group is completed by the second workstation 2. The lighter assembled at the third workstation 3 is transported to at least the fourth workstation 4 for assembly of the outlet valve.
