15 is a view for explaining the take-out means 800, the take-out means 800 for taking out the assembled cooler to the outside of the assembly apparatus as described above collectively jig in the horizontal direction by the jig transfer means (500) When transferring, the cooling fin (F) may be composed of an arm 802 to hang while supporting the refrigerant pipe (P) assembled from the jig (100).

The arm 802 is composed of a free end and a fixed end fixed to the frame FR. A plurality of arms 802 are installed at regular intervals.

The arm 802 has a free end having an upward inclined surface 804. When all the jigs 100 are collectively transferred through the jig transfer means 500 due to the upwardly inclined surface 804, the assembly is completed. The refrigerant pipe (P) of the cooler is separated by being taken out of the jig (100) while sliding and moving up along the inclined surface (804).

When assembling the cooler using the refrigerator cooler assembly apparatus according to the present invention as described above are as follows.

The cooler assembly apparatus of the present invention is assembled while the cooling pin inserting device 200, the refrigerant pipe inserting means 300, the cooling pin fixing means 400 are simultaneously operated in different jigs in each jig 100 installed in parallel directions. The work is carried out so that the last completed jig is taken out continuously.

And when this operation is completed, the jig conveying means 500 transfers all the jig 100 in a batch, and in this case, the cooler that is in the state of being assembled to the most end jig 100 is assembled through the take-out means 800 It is taken out to the outside.

First, in order to insert the cooling fins into the jig 100 using the cooling fin inserting apparatus 200, the cooling fins F are loaded on the cooling fin stacking portion 202 and the transfer mechanism 204 and the cooling fin inserting mechanism 206. ).

Then, as the motor 216 of the transfer mechanism 204 is driven, the cooling pin loading part 202 and the cooling pin insertion mechanism 206 are guide bars 212 by the rotation of the pinion 218 geared to the rack 220. Move along the horizontal direction.

At this time, the driving motor 212 of the cooling fin insertion mechanism 206 is also driven to transmit a driving force to the rotating shaft 226 through the belt 224 so that the roller 228 is cooled at the lower end mounted on the upper surface of the jig 100. It moves while pressing pin F downward.

And when the cooling fin (F) at the lowermost part passes through the point located in the insertion groove 102 of the jig 100, the support force of the cooling fin (F) is released and at the same time the pressing force by the rotation of the roller 228 As a result, the cooling fins F are forcibly moved downwardly into the insertion grooves 102 of the jig 100.

When one cooling fin F is inserted into the insertion groove 102 of the jig 100, the cooling fins loaded on the cooling fin loading unit 202 move downward and the lowermost cooling fin is supported by the roller 228. When the insertion standby state of the jig 100 is passed while maintaining the insertion standby state, the cooling fin F of the lowermost end of the loading part 202 is pushed by the roller 228 as described above. By repeatedly performing the process of forcibly inserting into the insertion groove 102 of the jig 100 is inserted along the insertion groove 102 of the cooling fin (F).

When the cooling fins F are all inserted along the insertion groove 102 of the jig 100, the signal of the limit switch installed at an arbitrary point of the frame FR is transmitted to the controller C to operate the transfer mechanism 204. To stop.

Then, the elevating mechanism 208 is driven through the control unit C to raise the cooling fin loading unit 202 and the cooling fin insertion mechanism 206 to the upper portion of the jig 100.

As described above, when the cooling pin inserting device 200 inserts the cooling fins F into the jig 100, the next jig 100 cools the insertion groove 102 of the jig 100 transferred before. If the pin (F) has been inserted, the operator should check the pin out and insert the pin by hand if there is no place.

Then, when this operation proceeds, the jig 100 which is sequentially installed next actuates the clamping mechanism 700 to press the jig 100 by the pressure plate 706.

In this state, the refrigerant pipe inserting means 300 and the cooling fin fixing means 400 are operated at the same time.

The operation of the coolant pipe inserting means 300 is to drive the coolant pipe P while the roller 304 rotates by driving the motor 302 to insert the coolant pipe F into the cooling hole F fixed to the jig 100. Insert P).

When the operation is performed, the next jig is operated by the cooling fin fixing means 400, and the cylinder 408 of the cooling fin fixing means 400 is driven to press the protrusion 410 at one end of the refrigerant pipe P. The outer circumferential surface is pressurized and fixed, and the leading end of the traction line 414 is inserted into the refrigerant pipe P until the leading end of the expansion tip 412 fits into the leading end of the refrigerant pipe P.

In this state, the traction line 414 exposed to the outside of the rear end of the refrigerant pipe P is fixed to the fixed body 418 of the traction mechanism 406, and then the motor 416 is driven to rotate the chain 424. While moving tow portion 420 is moved to one side, the traction line 414 fixed to the fixed body 418 also moves.

In this operation, the expansion tip 412 also moves along the traction line 414 along the inside of the refrigerant pipe P to expand the diameter of the refrigerant pipe P so that the outer circumferential surface of the refrigerant pipe P is the cooling fin F. It is fixed in surface contact with the hole of).

As such, when the fixing of the cooling fins F to the outer circumferential surface of the refrigerant pipe P is completed by the cooling fin fixing means 400, the assembly of the cooler is completed. Then, the jig clamping mechanism 700 is raised to increase the jig 100. Releases the pressurized state, and then the jig transfer means 500 is driven by the control of the control unit C.

The jig feeder 500 is driven by the horizontal feed mechanism 502. The spur gear 506 is rotated by the driving of the motor, and the rack gear 508 coupled to the gear moves in the horizontal direction. The locking projection 114 of the pallet 112 is caught by the locking step 510 of the 508 and all the jigs 100 are pushed and transferred in a horizontal direction collectively.

At this time, the cooler, which is assembled to the jig 100 at the extreme end, slides and moves up along the upward inclined plane 804 of the arm 802, which is the ejecting means 800, while being separated from the jig 100 while being separated. 802.

When the cooler assembled as described above is taken out and all the jigs 100 are transferred to one side, the first cylinder 516 is driven and raised by the control of the controller C, and the pallet formed on the upper surface of the first cylinder 516. The hook 528 hangs the pallet 112 and lowers the jig 100 supported by the support holder 110 together with the pallet 112.

When the lowering of the first cylinder 516 is completed, the signal is transmitted to the control unit C, and the transfer unit 518 is operated by the driving of a motor (not shown) under the control of the control unit C, and the rotating shaft 522 is operated. ) Is rotated to rotate the chain 526, and at this time, the engaging portion provided on the chain 526 moves the pallet hook 528 to move the jig 100 placed therein to the location where the second cylinder 520 is located. .

When the jig 100 is transferred to the second cylinder 520 by the operation of the transfer unit 518, a signal of a position sensor (not shown) is transmitted to the control unit C to control the control unit C. While the two cylinders 520 are driven, the pallet 112 and the jig 100 are transferred and placed to an empty initial position.

When the horizontal transfer mechanism 502 and the circulation transfer mechanism 504 are completed as described above, the spur gear 506 rotates in the opposite direction to the reverse rotation of the motor under the control of the control unit C, and thus the rack gear ( 508) to its original position.

When the jig 100 is transferred by the jig transfer means 500, the cooling fin insertion device 200 operates the transfer mechanism 204 under the control of the control unit C, so that the motor 216 uses the cooling fins. Rotate in the opposite direction of insertion.

With this action, the pinion 218 rotates along the guide bar 212, and the cooling fin insertion device 200 is reversed and returned to the initial position.

Then, as described above, the process of inserting the cooling fins F into the jig 100 while driving the cooling fin insertion apparatus 200 is repeated, and at the same time, the refrigerant pipe inserting means 300 in each jig 100, Cooling pin fixing means 400 is operated together to repeat the process of manufacturing a continuously completed cooler.
