Description

Technical Field

[0001] This invention relates to the field of conductive connector assembly technology, specifically to an industrial gateway connector plug assembly machine. Background Technology

[0002] Installing rubber plugs on the conductors of industrial gateway connectors effectively prevents oxidation when the connectors are not in use. Users can also cut the plugs into pieces to fill any looseness during connection, ensuring proper tightness. Currently, the assembly of industrial gateway connectors and rubber plugs primarily relies on manual operation. During manual assembly, operators must manually remove each connector and align it with the rubber plug. This process is prone to fatigue, leading to low efficiency. Furthermore, manual operation lacks precise pressure control, and uneven pressure during plug insertion can result in poor sealing or structural damage.

[0003] Meanwhile, manual handling of industrial gateway connectors and plugs presents an efficiency bottleneck. Each loading, assembly, and unloading requires repeated picking and placing actions, making it difficult to maintain a consistent production rhythm and failing to meet the continuous production needs of automated production lines.

The first feeding component also includes a... A feeding cylinder 105 is fixedly installed on the first vertical fixed plate 101. The telescopic cylinder of the feeding cylinder 105 is fixedly engaged with the first vertical fixed plate 101. A clamping support frame 106 is fixedly installed at the end of the telescopic rod of the feeding cylinder 105. Two clamping arms 109 are symmetrically rotated and installed on the clamping support frame 106. A clamping electromagnet 110 is fixedly provided between the opposite surfaces of the two clamping arms 109. A synchronous gear 107 is coaxially fixed at the rotational connection between each clamping arm 109 and the clamping support frame 106. The two synchronous gears 107 mesh with each other.

The two ends of the rubber strip 113 are fixed to the rotating shaft 112 and the rubber strip fixing block 114 respectively.

[0029] The second feeding assembly includes a linear motor 213, with a negative pressure air pump 214 fixedly mounted at the bottom of the actuator rod of the linear motor 213. A suction nozzle 215 is fixedly mounted at the air inlet of the negative pressure air pump 214, used to assemble the rubber stopper 209 onto the industrial gateway connector 305. The second feeding assembly also includes a rubber stopper feeding chute 203 and a rubber stopper pusher plate base 204, which are fixedly mounted on the operating table 401 via a third vertical fixing plate 202 and a second vertical fixing plate 201, respectively. A rubber stopper pushing cylinder 205 is fixedly mounted on the rubber stopper pusher plate base 204, with the telescopic cylinder of the cylinder 205 fixed to the rubber stopper pusher plate base 204. In conjunction with this, a rubber stopper positioning sliding cover 206 is fixedly mounted on the rubber stopper push plate base 204 along the axial direction of the rubber stopper push cylinder 205. A rubber stopper pusher slide 207 is slidably installed inside the rubber stopper positioning sliding cover 206. The rubber stopper pusher slide 207 is fixedly installed at the end of the telescopic rod of the rubber stopper push cylinder 205. A rubber stopper filling groove 223 for accommodating the rubber stopper 209 is opened at the end of the rubber stopper pusher slide 207 away from the rubber stopper push cylinder 205. The rubber stopper feeding chute 203 is aligned with the rubber stopper positioning sliding cover 206, and the rubber stopper filling groove 223 can slide to a position aligned with the rubber stopper feeding chute 203. The rubber stopper feeding chute 203 is used to supply the rubber stopper 209 into the rubber stopper filling groove 223. The second feeding assembly also includes a lifting cylinder 224. The end of the telescopic rod of the lifting cylinder 224 is fixedly equipped with a lifting strip 208. The lifting strip 208 slides and contacts the rubber plug 209 to prevent the rubber plug 209 from falling off the rubber plug filling groove 223. The lifting cylinder 224 is fixedly installed on the fourth vertical fixing plate 210. The fourth vertical fixing plate 210 is fixedly installed on the operating table 401. A linear motor fixing plate 211 is fixedly installed on the top of the fourth vertical fixing plate 210. The linear motor 213 is fixedly installed on the linear motor fixing plate 211. The end of the linear motor fixing plate 211 away from the fourth vertical fixing plate 210 is fixedly supported on the operating table 401 by two parallel support rods 212. The fourth vertical fixing plate 210 is also provided with a slotted window 222 for the locking electromagnet 219 to pass through. The locking electromagnet 219 is slidably mounted on the locking sliding base plate 217. A locking cylinder 218 is fixedly mounted on the locking sliding base plate 217. The telescopic cylinder of the locking cylinder 218 is fixedly engaged with the locking sliding base plate 217. The end of the telescopic rod of the locking cylinder 218 is fixedly engaged with the locking electromagnet 219. Two parallel guide rods 220 are fixedly mounted on the lower surface of the locking sliding base plate 217. Both guide rods 220 are slidably inserted into the locking support beam 216. A tension spring 221 is arranged around both guide rods 220. The two ends of the tension spring 221 are fixedly engaged with the locking sliding base plate 217 and the locking support beam 216.

[0030] The unloading assembly includes four unloading swing arms 302 rotatably mounted on a rotating support frame 301. The four unloading swing arms 302 are fixed perpendicularly to each other as a single unit. Each unloading swing arm 302 has a placement plate swing groove 304 at its end away from its own rotation axis. A placement plate 303 is rotatably mounted in each placement plate swing groove 304. The placement plate 303 is provided with an insertion through hole 311 for inserting an industrial gateway connector 305. Two magnetic counterweight rods 307 are also symmetrically rotatably mounted on each unloading swing arm 302. A magnetic counterweight 306 is fixedly mounted at the end of each magnetic counterweight rod 307 away from the placement plate 303. The two magnetic counterweight rods 307 are perpendicular to the plane of the placement plate 303. The two magnetic counterweight rods 307 and the placement plate 303 are coaxially fixed and driven by a rotating shaft. The magnetic counterweight 306 is magnetically attracted to the locking electromagnet 219. Each magnetic counterweight lever 307 is coaxially connected to the shelf 303 and is fixed with a swing gear 308. The swing gear 308 is used to drive the shelf 303 to swing in the shelf swing groove 304. An arc-shaped rack bracket 310 is also fixedly installed on the rotating support frame 301. The arc-shaped rack bracket 310 is located on the side away from the fourth vertical fixed plate 210. An arc-shaped rack 309 that can mesh with the swing gear 308 is fixedly installed at the end of the arc-shaped rack bracket 310 away from the rotating support frame 301. The rotating support frame 301 is fixedly installed on the operating table 401. A stabilizing magnet 313 that magnetically cooperates with the magnetic counterweight 306 is fixedly installed at the top of the rotating support frame 301. All the unloading swing arms 302 are driven by a rotating servo motor 312 fixedly installed on the first vertical fixed plate 101. A worm gear transmission mechanism is provided in the transmission path between the output shaft of the rotating servo motor 312 and the unloading swing arm 302 to prevent the unloading swing arm 302 from rotating due to external force.

[0031] A clapping motor 104 is also fixedly installed on the first vertical fixing plate 101. An auxiliary clapping plate 103 is fixedly installed on the output shaft of the clapping motor 104. The auxiliary clapping plate 103 contacts and engages with the industrial gateway connector 305 to knock the industrial gateway connector 305 off the shelf 303.

[0032] Both the industrial gateway connector feeding chute 102 and the rubber plug feeding chute 203 are fed by vibratory feeders, allowing the industrial gateway connector 305 to move on the industrial gateway connector feeding chute 102 to the U-shaped insert plate 111, and allowing the rubber plug 209 to move into the rubber plug filling groove 223.

[0033] During operation, the industrial gateway connector loading chute 102 moves the industrial gateway connector 305 onto the U-shaped insert plate 111. Then, the transfer servo motor 116 is controlled, and its output shaft drives the transfer plate 115 to swing 180 degrees (180 degrees for the first use, 90 degrees for subsequent uses), moving the industrial gateway connector 305 to one side of the clamping arm 109. The two clamping electromagnets 110 are then controlled to generate a repulsive magnetic force, putting the two clamping arms 109 in an open state. The industrial gateway connector 305 can then move between the two clamping arms 109. The two clamping electromagnets 110 are then controlled again to generate an attractive magnetic force, closing the loop and clamping the industrial gateway connector 305. The synchronous gear 107 ensures that the swing angles of the two clamping arms 109 are consistent, keeping them in a symmetrical state. After clamping the industrial gateway connector 305, the transfer servo motor 116 is controlled to rotate 90 degrees again. At this time, since the industrial gateway connector 305 is placed on the U-shaped insert plate 111 (the U-shaped insert plate 111 is U-shaped so that it can be aligned with the industrial gateway connector loading chute 102, allowing the industrial gateway connector 305 on the industrial gateway connector loading chute 102 to move onto the U-shaped insert plate 111), when the transfer plate 115 swings, it will drive the U-shaped insert plate 111 to swing, and then the corresponding rotating shaft 11 on the U-shaped insert plate 111 will swing. The rubber strip 113 will then rotate relative to the transfer plate 115, causing it to stretch and deform. Since the industrial gateway connector 305 is fixed by the clamping arm 109, all industrial gateway connectors 305 will separate from the U-shaped insert plate 111. Under the action of the rubber strip 113, the U-shaped insert plate 111 will swing back to its initial position. When the transfer servo motor 116 rotates another 90 degrees, the U-shaped insert plate 111 will align with the industrial gateway connector loading chute 102 again, allowing the industrial gateway connectors 305 to re-enter the U-shaped insert plate 111. When the transfer plate 115 is positioned perpendicular to the first vertical fixing plate 101 along its length, the extension rod of the loading cylinder 105 can move. This includes the process of clamping the industrial gateway connector 305 and the process of releasing the industrial gateway connector 305. The extension rod of the loading cylinder 105 drives the clamped industrial gateway connector 305 to move towards the insertion through hole 311 on the placement plate 303, so that the industrial gateway connector 305 is inserted into the insertion through hole 311. Then, the two clamping electromagnets 110 are controlled to repel each other again, and the industrial gateway connector 305 is released. The loading cylinder 105 is controlled to retract to the initial position again (after reaching the position, the transfer servo motor 116 is controlled to rotate 90 degrees) to facilitate clamping the industrial gateway connector 305 on the next U-shaped insert plate 111.

[0034] The rotary servo motor 312 is controlled to swing its output shaft 90 degrees, causing the top vertically mounted unloading swing arm 302 to swing horizontally towards the fourth vertical fixed plate 210. The magnetic counterweight 306 is used to keep the shelf 303 in a horizontal position. At this time, the shelf 303, which carries the industrial gateway connector 305, will move directly below the suction nozzle 215. Then, the locking cylinder 218 is controlled, and its extension rod extends, causing the locking electromagnet 219 to move below the magnetic counterweight 306. The locking electromagnet 219 is then activated, generating a magnetic force that attracts the magnetic counterweight 306. The reaction force will then stretch the tension spring 221, which restricts the shelf 303 to a horizontal position. At the same time, the locking electromagnet 219 and the magnetic counterweight 306 come into contact and attract each other, thus restricting the shelf 303. The control cylinder 205 pushes the rubber stopper forward. Its extension rod moves the rubber stopper pusher slide 207, allowing the rubber stopper filling groove 223, carrying the rubber stopper 209 inside, to move below the suction nozzle 215. Before this, the control cylinder 224 pushes the control cylinder 224. Its extension rod moves the control bar 208 to a position close to the rubber stopper pusher slide 207, allowing the rubber stopper 209 to slide against the control bar 208, preventing the rubber stopper 209 from slipping out of the rubber stopper filling groove. The rubber stopper 209 is removed from the groove 223. Then, the linear motor 213 is controlled, and the actuator of the linear motor 213 drives the suction nozzle 215 on the negative pressure air pump 214 to move to contact the rubber stopper 209. Then, the negative pressure air pump 214 is started, and the negative pressure air pump 214 suctions the rubber stopper 209 through the suction nozzle 215. Then, the rubber stopper 209 is removed from the rubber stopper filling groove 223 (by the linear motor 213 driving the rubber stopper 209 to move upward a certain distance from the rubber stopper filling groove 223). Then, the extension rod of the rubber stopper pushing cylinder 205 is controlled to retract, aligning the rubber stopper filling groove 223 with the rubber stopper feeding slide 203. This allows the rubber stopper 209 inside the rubber stopper feeding slide 203 to enter the rubber stopper filling groove 223 for the next assembly. Simultaneously, the extension rod of the lifting cylinder 224 is controlled to retract, separating the lifting bar 208 from the rubber stopper pushing slide bar 207. This moves the rubber stopper pushing slide bar 207 and the lifting bar 208 away from under the negative pressure air pump 214. Then, the linear motor 213 is controlled, and its actuator drives the rubber stopper 209 to be inserted into the industrial gateway connector 305, achieving the assembly of the industrial gateway connector 305 and the rubber stopper 209. Finally, the locking electromagnet 219 is de-energized, and the extension rod of the locking cylinder 218 is controlled to pull the locking electromagnet 219 away from under the negative pressure air pump 214.

[0035] The rotary servo motor 312 is controlled to drive the unloading swing arm 302 to rotate again. When the placement plate 303 corresponding to the assembled industrial gateway connector 305 moves to a position close to the clapping motor 104, the corresponding swing gear 308 will engage with the arc rack 309. Then, the arc rack 309 will restrict the swing gear 308, causing the swing gear 308 to rotate and swing. The swing gear 308 drives the placement plate 303 to swing 180 degrees, causing the industrial gateway connector 305 on the placement plate 303 to flip over. Under the action of gravity, the industrial gateway connector 305 falls out of the insertion through hole 311. To prevent the phenomenon of not falling out, the clapping motor 104 is started each time. The output shaft of the clapping motor 104 drives the auxiliary clapping plate 103 to clap the industrial gateway connector 305, causing it to fall out. Then, a conveyor belt sliding groove is set below the fall-out to catch the assembled industrial gateway connector 305. When the oscillating gear 308 separates from the arc rack 309, the magnetic counterweight 306 will swing to a position below the shelf 303 under the action of gravity. During this process, the shelf 303 will shake. When the magnetic counterweight 306 moves to a position close to the stabilizing magnet 313, the shaking of the shelf 303 and the magnetic counterweight 306 is stabilized by magnetic attraction.
