Description

Technical Field

[0001] This utility model relates to an assembly tool for a bellows at the intake end of an automobile. Background Technology

[0002] A car intake bellows is a pipe with a corrugated shape. Its internal cavity is designed with waves to effectively reduce noise and vibration. It is mainly used to increase the intake volume and reduce the intake resistance before the throttle valve. Its opening and placement design allows more fresh air to be drawn in.

[0003] Both ends of the automotive intake bellows must be fitted with a connector for communication with other components. To prevent the connectors from detaching, adhesive must be applied to the inside of the openings at both ends of the bellows before installation. Currently, the application of adhesive and installation of automotive intake bellows are mostly done manually, resulting in low efficiency. Furthermore, these two processes are separate and independent, making the operation cumbersome. The automotive intake bellows require loading and unloading before and after adhesive application and installation, wasting considerable time. In addition, loading and unloading are also mostly done manually, further reducing efficiency and increasing labor costs, requiring further improvement. Utility Model Content

[0042] Working principle:

[0043] Multiple air inlet bellows 7 are horizontally placed into the storage chamber 49. The bottommost and foremost air inlet bellows 7 will roll along the slope of the base plate 41 into the discharge chamber 410. The internal height of the discharge chamber 410 only allows a single row of air inlet bellows 7 to enter. In the initial state, the baffles 46 in both baffle units extend into the discharge chamber 410, so when the air inlet bellows 7 located in the discharge chamber 410 is blocked by the rear baffle 46, it will stop rolling. Then, the extension of the rear baffle cylinder 45 is driven first. The constricting end retracts inward to move a rear baffle 46 upward, thereby causing the aforementioned air inlet bellows 7 to continue rolling until it is blocked by a front baffle 46. Then, the telescopic end of a rear baffle cylinder 45 is driven to extend outward to reset the baffle 46 and block the next air inlet bellows 7 entering the discharge chamber 410. Subsequently, the telescopic end of a front baffle cylinder 45 is driven to retract inward to move the baffle 46 upward so that the aforementioned air inlet bellows 7 continues to roll until it rolls onto the two beams 316 in the translational conveyor line 31.

[0044] A gap is formed between any two adjacent partitions 315. The air intake bellows 7 will fall into the two nearest gaps. Then, the power motor 313 in the power unit is started to rotate its rotating shaft. Then, the two transmission rods 311 drive the two transmission chains 314 to run synchronously, thereby driving the air intake bellows 7 to move towards the glue application assembly 32.

[0045] When the air inlet bellows 7 moves above the two first pneumatic fingers 321 in the glue application assembly 32, the power motor 313 is turned off and the two grippers of each first pneumatic finger 321 are driven to swing and approach each other to clamp the two ends of the air inlet bellows 7. Then, the telescopic end of the adjusting cylinder 322 in each glue application unit is driven to extend outward or retract inward to drive each dispensing valve 323 to tilt and move towards the air inlet bellows 7, thereby driving the end opening of each dispensing nozzle 324 to extend into the corresponding end opening of the air inlet bellows 7 and adhere to the inner wall of the opening. Then, the dispensing valve 323 can be activated to apply glue through the dispensing nozzle 324 to the inner wall of the two end openings of the air inlet bellows 7. At the same time, the steering also needs to be driven. The telescopic end of the clamping cylinder 325 in the clamping module of the unit extends outward to drive both driven assemblies to move downward until the two pulleys 327 in each driven assembly are pressed against the outer wall of the air inlet bellows 7. At the same time, the outer wall of the air inlet bellows 7 is pressed against the outer wall of the conveyor belt 3214. Then, the steering motor 329 in the active module of the steering unit is started to rotate its rotating shaft. Then, one of the active rollers 3211 is driven to rotate by the first pulley 3210, the second pulley 3212 and the synchronous belt 3213. Then, the other active roller 3211 drives the conveyor belt 3214 to run, and then the air inlet bellows 7 is driven to rotate by friction. This causes the glue to be applied circumferentially along the inner wall of the openings at both ends of the air inlet bellows 7.

[0046] After the adhesive is applied, the steering motor 329 is turned off and the telescopic end of the clamping cylinder 325 is driven to retract inward so that each pulley 327 is moved away from the outer wall of the air inlet bellows 7. Then, the telescopic end of each adjusting cylinder 322 is driven to retract inward or extend outward so that the end opening of each dispensing nozzle 324 comes out from the inside of the openings at both ends of the air inlet bellows 7. Then, the two grippers of each first pneumatic finger 321 are driven to swing away in opposite directions to release the air inlet bellows 7. Then, the power motor 313 is restarted to drive the air inlet bellows 7 to continue moving towards the spinning assembly 33 in the same way.

[0047] When the inlet bellows 7 moves above the two second pneumatic fingers 335 in the spinning assembly 33, the power motor 313 is turned off and the two grippers of each second pneumatic finger 335 are driven to swing and approach each other to clamp the two ends of the inlet bellows 7. Then, a connector is installed inside the sleeve 334 in each spinning unit. Subsequently, the telescopic ends of the shift cylinder 332 in each spinning unit are driven to retract inward or extend outward so that each spinning motor 333 is driven to move towards the inlet bellows 7 by means of each bracket 331. Then, the two connectors are driven to move laterally towards the openings at both ends of the inlet bellows 7 by means of the two sleeves 334 until the ends of the two connectors are inserted into the openings at both ends of the inlet bellows 7.

[0048] Finally, each spinning motor 333 is started simultaneously to rotate its rotating shaft, which in turn drives each connector to rotate through the sleeve 334, so that the external thread on the end of each connector is screwed into the internal thread inside the openings at both ends of the air inlet bellows 7, thereby realizing the automatic assembly of the connector; moreover, the glue will be evenly distributed between the connector and the air inlet bellows 7, and after the glue solidifies, the connector cannot be easily separated from the air inlet bellows 7.

[0049] After assembly, first drive the two grippers of each second pneumatic finger 335 to swing away from each other to loosen the two ends of the air inlet bellows 7. Then drive the telescopic ends of the shift cylinders 332 in each spinning unit to extend outward or retract inward to drive the sleeves 334 to disengage from the joint. Then restart the power motor 313 to drive the air inlet bellows 7 to continue moving in the same way until it automatically disengages from the translation conveyor line 31.

[0050] This invention can automatically complete the gluing and joint installation processes of automotive air intake bellows on the same machine, eliminating the need for manual labor and thus improving work efficiency and simplifying operation steps. At the same time, the feeding mechanism 4 and the translation conveyor line 31 enable automatic feeding, automatic transfer and automatic unloading of automotive air intake bellows, thereby saving a lot of time and further improving work efficiency, while also reducing labor costs.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
