DETAILED DESCRIPTION

[0066] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] like Figure 1-50As shown, the fully automatic assembly production line for assembling components of the lighter before inflation includes a first workstation 1 for assembling a body, a bottom cover and a shell component. The first workstation 1 is connected to a third workstation 3 for receiving the lighter assembled by the first workstation 1 and continuing to assemble parts thereon. A second workstation 2 connected to the third workstation 3 for automatically assembling and assembling the lighter straw and the zinc sleeve is provided between the third workstation 3 and the first workstation 1. A fourth workstation 4 connected to the third workstation 3 for assembling the air outlet valve on the lighter is provided on one side of the third workstation 3.

[0068] The first workstation 1 includes 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 6 is provided between the first workstation 1 and the third workstation 3, which can transfer the lighters assembled at the first workstation 1 to the third workstation 3. The structure of the first transfer robot 6 is similar to that of the second discharge assembly robot 2900, and the difference lies in the clamping structure.

[0069] 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 with 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.

[0070] When the present invention is used, 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 puts it into the first circulation conveying mechanism 1300, and circulates it in the first circulation conveying mechanism 1300, and then 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.

[0071] 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.

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.

[0073] 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.

[0074] 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.

[0075] A first shell grouping assembly 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 assembly 1211 is used to group several lighter shells into one group, and in the subsequent assembly process, the group is used as a unit for simultaneous assembly operation.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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. At this time, the first turning conveying motor 1207 is started, and the first turning conveying motor 1207 drives the first brush 208 to rotate. The first brush 208 assists the lighter shell in the arc conveying groove 205 to turn and convey. After changing the conveying direction, it is continued to be conveyed by the first No. 2 straight conveying section 1203 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. During the sliding process, the first driving groove 1218 undergoes relative displacement with the first protrusion 1219, combined with Figure 3 As shown, at this time, one of the two first grouping rod bodies 1216 is pushed outward, and the other is retracted inward. When grouping, the first grouping rod body 1216 on the left side of the figure is pushed out first to play a limiting role. The lighter shell stops at the first grouping rod body 1216, and then another first grouping rod body 1216 is used to push out, so that the lighter shells between the two first grouping rod bodies 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.

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.

[0082] The first drive assembly 1402 includes a horizontal drive assembly and a vertical drive assembly whose driving directions are perpendicular to each other.

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.

[0203] Preferably, the thickness of the second zinc sleeve clamp 2961 is smaller than the thickness of the second jaw 2960, so that the second zinc sleeve clamp 2961 can easily enter the second No. 2 jaw extension slot 2851 and the second No. 1 jaw extension slot 2831, and a straw zinc sleeve group 3 to be clamped is arranged between the second No. 2 jaw extension slot 2851 and the second No. 1 jaw extension slot 2831, and the straw zinc sleeve group 3 includes a straw 2 and a zinc sleeve 1 that has been assembled on the straw 2, the cross-sections of the straw 2 and the zinc sleeve 1 are T-shaped and have a center hole, and the widths of the second No. 2 jaw extension slot 2851 and the second No. 1 jaw extension slot 2831 are smaller than the diameter of the zinc sleeve 1.

[0204] The specific working principle of the second workstation is as follows:

[0205] 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.

[0206] 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.

[0207] Working principle of the second zinc sleeve lifting assembly mechanism 2600: the second top 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.

[0208] 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.

[0209] When the zinc straw set 3 rotates to approach the second material receiving seat 2431, the second vertical top rod 2423 of the second self-resetting tube pusher 2420 contacts the second discharging top plate 2410, causing the second vertical top rod 2423 to drop vertically, and the dropped second vertical top rod 2423 causes the second horizontal top 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 discharging spacing mechanism 2800 through the discharging channel 491.

[0210] 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 after the spacing is completed, the 5 groups of zinc straw sets 3 are taken away at one time by the second discharging assembly robot 2900.

[0211] 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.

[0215] Specifically, the third rotating mechanism 31 includes a third support frame 311 and a third rotating disk 312 rotatably connected to the third support frame 311, a driving motor (not shown in the figure) is fixedly connected to the third support frame 311 and drivingly connected to the third rotating disk 312, and the third clamp 3100 is fixedly connected to the edge of the upper surface of the third rotating disk 312.

[0216] Preferably, twelve third clamps 3100 are provided and are evenly distributed along the circumference of the axis of the third rotating disk 312 .

[0217] The third clamp 3100 includes a third clamp base 3101 fixedly connected to the third rotating disk 312.

[0218] When in use, the lighter housing is mounted on the third fixture base 3101 through the third mounting groove 3102, and the third fixture base 3101 is fixedly mounted on the rotating station, so that the lighter housing passes through several assembly stations in sequence by driving the third fixture base 3101. Therefore, the present invention is provided with a third fixture base 3101 with a third mounting groove 3102, and the lighter housing is mounted on the third fixture base 3101 through the third mounting groove 3102, and the third fixture base 3101 can be fixedly mounted on the rotating station, so that the lighter housing is driven to pass through several subsequent assembly processes in sequence to achieve automatic assembly.

[0219] Preferably, there are five third mounting grooves 3102 and they are arranged parallel to each other, and the distance between two adjacent third mounting grooves 3102 is equal. In this way, five lighters can be automatically assembled at the same time, thereby improving production efficiency.

[0220] The third fixture base 3101 is also provided with a third reserved groove 3103 in an arc shape, the third reserved groove 3103 is connected to the third installation groove 3102, and any two adjacent sides of the third installation groove 3102 are transitionally connected through the third reserved groove 3103. This can prevent the third installation groove 3102 on the third fixture base 3101 from being deformed due to thermal expansion and contraction when the temperature changes during use, thereby causing the lighter shell to be unable to be installed; and also includes a third stabilizing component 3104 fixedly connected to the third fixture base 3101 for improving the installation stability of the lighter shell, and the third stabilizing component 3104 is located above the third installation groove 3102. The third stabilizing component 3104 is used to further stabilize the lighter shell installed in the third installation groove 3102 to prevent the lighter shell from being separated during assembly and causing assembly failure.

[0221] Specifically, the third stabilizing assembly 3104 includes two third bases 3105 respectively fixedly connected to the two ends of the third fixture base 3101, the two ends of the fixing plate group 106 are fixedly connected to the third base 3105, the middle of the third mounting plate group 3106 is suspended above the third fixture base 3101, and the fixing plate group 106 is also provided with a third stabilizing hole 3107 that penetrates the fixing plate group 106. The third stabilizing hole 3107 is located directly above the third mounting groove 3102, and the third stabilizing hole 3107 is provided in a plurality and is arranged one-to-one with the third mounting groove 3102. The bottom of the lighter housing is installed in the lighter shell, and the middle part is clamped by the third stabilizing hole 3107.

[0222] The fixing plate assembly 106 includes a third first clamping plate 3108 and a third second clamping plate 3109 which are arranged opposite to each other. The third stabilizing hole 3107 is located between the third first clamping plate 3108 and the third second clamping plate 3109. There is also a third gap 3110 between the third first clamping plate 3108 and the third second clamping plate 3109. Two adjacent third stabilizing holes 3107 are connected through the third gap 3110. The third stabilizing hole 3107 is composed of two third half holes 3111 which are located opposite to each other. One end of the third half hole 3111 is connected to the third gap 3110, and the other end extends to the inside of the third first clamping plate 3108 or the third second clamping plate 3109. The third first clamping plate 3108 and the third second clamping plate 3109 in the third stabilizing assembly 3104 are fixedly arranged, and the third stabilizing hole 3107 therebetween is preset to a size that matches the size of the lighter housing.

[0223] Preferably, the width of the third half hole 3111 gradually decreases from one end close to the third slit 3110 to the other end, and the end of the third half hole 3111 is in an arc shape. Preferably, the width of the rear end of the third half hole 3111 can be set to be slightly smaller than the width of the lighter housing, so that the side wall of the third half hole 3111 can be used to clamp the outer surface of the lighter housing, thereby improving stability.

[0224] The third feeding assembly 321 includes a third vibration disk 323 and a third material guide trough 324 which are interconnected. 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.

[0225] The working principle is: when in use, the lighter housing with components such as flat gaskets and constant flow valves to be assembled is clamped in the third fixture 3100, and 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, and the third vibration disk 323 conveys the components 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.

[0226] The fourth workstation 4 includes a fourth frame 1 and a fourth conveying line 2 arranged on the fourth frame 1.

A fourth transfer manipulator 7 capable of transferring the lighters assembled at the third workstation 3 to the fourth workstation 4 is provided between the third workstation 3 and the fourth workstation 4. The fourth transfer manipulator 7 is similar in structure to the second discharging assembly manipulator 2900, except for the clamping structure.

[0227] 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.

[0228] 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. One end of the fourth material feeding pipe 435 away from the fourth vibration plate 434 is connected to the fourth material guiding component 432. The fourth material guiding component 432 includes a fourth material guiding body 436 fixedly connected to the fourth frame 41. At least one fourth material guiding trough 437 is provided on the fourth material guiding body 436. The fourth material guiding trough 437 is located directly above the fourth conveying line 42. One end of the fourth material guiding trough 437 away from the fourth conveying line 42 is connected to the fourth material feeding pipe 435.

[0229] 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.

[0230] 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.

[0231] 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.

[0232] 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 conveyor 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.

[0233] 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.

[0234] 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.

[0235] 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 arranged on the fourth mounting plate 4105 , and a fourth output shaft 4107 is connected to the fourth cylinder 4106 .

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] Preferably, a plurality of fourth sleeves 4110 are fixedly connected to the fourth pressing plate 4108, the fourth sleeves 4110 are slidably connected to the fourth guide rods 4111, and the fourth 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. The sliding cooperation between the fourth guide rods 4111 and the fourth sleeves 4110 plays a guiding role in the sliding direction of the fourth pressing plate 4108.

[0241] The fourth locking assembly 4103 includes a fourth locking platform 4112 fixedly connected to the fourth elastic buffer assembly 4104, and at least one fourth locking head 4113 is fixedly connected to the fourth locking platform 4112. The fourth locking platform 4112 can ensure that the pressure applied to each fourth locking head 4113 is uniform.

[0242] 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.

[0243] 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.

[0244] The working principle of the fourth workstation is: when in use, the lighter assembled at the third workstation 3 is transferred to the fourth workstation 4 through the fourth transfer manipulator 7, and is transported to the bottom of the fourth air valve feeding mechanism 43 through the fourth conveying line 42. At this time, the fourth vibration disk 434 is started, and the air valve in the fourth vibration disk 434 is 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 whose air valve is to be locked 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 whose air valve is to be locked 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.

[0245] The fourth conveyor line 2 is also provided with a lighter delivery mechanism, which includes a fifth discharge platform 10, on which a fifth empty box conveying channel 11 and a fifth full box conveying channel 12 are provided, and the fifth empty box conveying channel 11 and the fifth full box conveying channel 12 are respectively provided with a fifth empty box conveying drive assembly 13 and a fifth full box conveying drive assembly 14, the side of the box outlet end of the fifth empty box conveying channel 11 is connected with the side of the box inlet end of the fifth full box conveying channel 12, a fifth empty box pushing assembly 15 is provided between the box outlet end of the fifth empty box conveying channel 11 and the box inlet end of the fifth full box conveying channel 12, and the fifth discharge platform 10 is also provided with a fifth manipulator 16 with variable jaw spacing.

[0246] The empty box is pushed to the discharge placement position by the fifth empty box conveying drive assembly 513, and then the lighter is grabbed by the fifth clamping jaw spacing variable manipulator 516 and moved into the empty box, and the fifth clamping jaw spacing variable manipulator 516 sequentially fills the empty box with a plurality of lighters. The empty box is in the fifth empty box conveying channel 511 and conveyed by the fifth empty box conveying drive assembly 513. When the empty box moves to the designated position, the empty box is pushed into the fifth full box conveying channel 512 by the fifth empty box pushing assembly 515, and the lighter is loaded at this time. After slow fire, the full box is moved and conveyed out of the discharge platform 10 by the fifth full box conveying drive assembly 514. When the full box is pushed into the fifth full box conveying channel 512, the fifth empty box pushing assembly 515 continues to work to move the next empty box to the discharge placement position.

[0247] In this process, the fifth jaw spacing variable manipulator 516 coordinates with various conveying drive components to complete sustainable discharge steps, and the entire process is automated and controllable.

[0248] The fifth empty box conveying passage 511 and the fifth full box conveying passage 512 are parallel to each other.

[0249] 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 fifth full box conveying channel 512 are parallel to each other, the connection between the fifth empty box conveying channel 511 and the fifth full box conveying channel 512 can be in a straight line. The empty box only needs to enter the fifth full box conveying channel 512 along the straight line from the fifth empty box conveying channel 511 to load the goods. The route is short and does not require changing direction, which prevents the occurrence of jamming.

[0250] Fifth side stop bars 517 are disposed on both sides of the fifth empty box conveying channel 511 and the fifth full box conveying channel 512 and the fifth side stop bars 517 are shared. A fifth front stop bar 518 is disposed at the box inlet end of the fifth empty box conveying channel 511 .

[0251] The fifth side bar 517 is located between the fifth empty box conveying channel 511 and the fifth full box conveying channel 512. On the one hand, it is used to separate the fifth empty box conveying channel 511 and the fifth full box conveying channel 512. On the other hand, it shares a path that greatly reduces the distance between the fifth empty box conveying channel 511 and the fifth full box conveying channel 512, that is, the length of the connecting port between the fifth empty box conveying channel 511 and the fifth full box conveying channel 512 is shorter, making it easier to transport boxes from the fifth empty box conveying channel 511 to the fifth full box conveying channel 512.

[0252] A fifth box in-and-out platform 519 is provided on the box inlet end of the fifth empty box conveying channel 511 and the box outlet end of the fifth full box conveying channel 512 .

[0253] The fifth box in and out platform 519 is used to place empty boxes and convey the empty boxes into the fifth empty box conveying channel 511, and is also used to output full boxes. The full boxes pass through the fifth full box conveying channel 512 to the fifth box in and out platform 519 for subsequent packaging and transportation of the full boxes.

[0254] The fifth empty box conveying driving assembly 513 includes a fifth belt conveyor 520 . The fifth belt conveyor 520 is connected to the fifth empty box conveying passage 511 . Fifth limit levers 521 are provided on both sides of the conveying belt of the fifth belt conveyor 520 .

[0255] A plurality of empty boxes are placed on the conveyor belt of the fifth belt conveyor 520. As the fifth belt conveyor 520 works, the empty boxes are transported into the fifth empty box conveying passage 511, and the empty boxes in the fifth empty box conveying passage 511 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 fifth empty box conveying passage 511.

[0256] The fifth full box conveying drive assembly 514 includes a fifth box pushing claw 522 arranged on the box input end of the fifth full box conveying channel 512, the fifth box pushing claw 522 is inserted into the fifth box pushing claw travel groove 523 of the discharge platform 10, and the lower end of the fifth box pushing claw 522 is connected to the fifth box pushing claw linear driver 524 at the bottom of the discharge platform 10.

[0257] When the empty box is pushed into the fifth full box conveying channel 512, the fifth box pushing claw 522 is located at one end of the empty box. After the empty box is filled with lighters, the fifth box pushing claw 522 slides in the fifth box pushing claw travel groove 523 under the operation of the fifth box pushing claw linear driver 524, and pushes the full box forward while sliding, so that space is reserved at the box entrance end of the fifth full box conveying channel 512 for placing the next empty box.

[0258] The fifth empty box pushing component 515 includes a fifth box pushing block 525 , and the fifth box pushing block 525 is connected to a fifth box pushing block linear driver 526 .

[0259] When the empty box is pushed and moved to the box inlet end of the fifth full box conveying channel 512 , the fifth box pushing block linear driver 526 operates to move the fifth box pushing block 525 and push the empty box to move into the fifth full box conveying channel 512 .

[0260] The fifth variable-distance gripper robot 516 includes a fifth XYZ three-axis robot 527 disposed on the discharge platform 10 , and the fifth XYZ three-axis robot 527 is connected to a fifth variable-distance mechanical gripper assembly 528 .

[0261] The fifth jaw spacing variable manipulator 516 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 different positions of the lighter and different positions of the socket on the box.

[0262] In addition, during the process of placing lighters, the lighters are placed side by side at the pickup area, and according to the distance between adjacent lighters, the fifth variable-distance mechanical clamp assembly 528 can also adjust and change the distance between adjacent clamps.

[0263] During the picking and placing process, the position is adjusted and the lighters are grabbed and placed through mechanical automation.

[0264] The fifth variable-pitch mechanical gripper assembly 528 includes a fifth air gripper worktable 529, on which a plurality of fifth air grippers 530 located in the same straight line are arranged, the fifth air grippers 530 are fixed on a fifth air gripper seat 531, and the plurality of fifth air gripper seats 531 are connected via a fifth cross-telescopic structure 532, and the fifth air gripper worktable 529 is provided with three fifth guide rods 533 parallel to the bottom surface, and the fifth guide rods 533 are connected to the fifth cross-telescopic structure 532, and a fifth variable-pitch linear drive 534 is provided at one end of the fifth air gripper worktable 529, and the fifth variable-pitch linear drive 534 is connected to the fifth cross-telescopic structure 532.

[0265] 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 fifth cross-telescopic structure 532. The fifth cross-telescopic structure 532 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 fifth air gripper seat 531 moves on the fifth guide rod 533, and the fifth guide rod 533 provides support for the fifth air gripper seat 531.

[0266] The number of fifth lighter sockets 536 on the same row of the fifth lighter base box 535 on the fifth empty box conveying channel 511 is at least twice the number of fifth air grippers 530, and the number of fifth lighter sockets 536 on the same row of the fifth lighter base box 535 is in a multiple relationship with the number of fifth air grippers 530, ensuring that all the air grippers can be used each time to grab the lighter, thereby improving work efficiency.

[0267] The working principle of the lighter delivery mechanism is as follows: the fifth belt conveyor 520 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 fifth empty box conveying channel 511; as the conveyor belt continues to drive, the empty boxes continue to move against the empty boxes in front, so that the empty boxes in the fifth empty box conveying channel 511 move to the box inlet end of the fifth full box conveying channel 512; then the fifth box pushing block linear driver 526 works to move the fifth box pushing block 525 and push the empty boxes to move into the fifth full box conveying channel 512. 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 works to extend its output axis outward or move inward, thereby pulling or pushing the fifth cross telescopic structure 532 to change the spacing between adjacent fifth air claws 530. Then, the lighter is clamped and released through ventilation and deflation of the fifth air claws 530, and the fifth XYZ three-axis manipulator 527 is moved in the xyz direction to finally insert the lighter into the empty box.

[0268] When the empty box is filled with lighters, the fifth box pushing claw 522 slides in the fifth box pushing claw travel groove 523 under the operation of the fifth box pushing claw linear driver 524, and pushes the full box forward while sliding, so that space is reserved for the next empty box at the box inlet end of the fifth full box conveying channel 512.

[0269] 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 assembly. At the third workstation 3, the zinc sleeve straw group, the flat gasket and the constant flow valve of the lighter are assembled.
