[0074] Working principle of the present invention:

[0075] The radiator welding workstation is used to connect to the discharge channel of the heat sink production line or the material input method of the stacked plate. It can complete automatic chip encoding, automatic body flipping, automatic full welding after manual spot welding, until the finished heat sink is moved out of the welding room for subsequent process flow.

[0076] In the initial state, the automatic chip mechanism 3 grabs the sheet on the discharge channel of the heat sink production line or the sheet on the stacking plate through multiple electromagnets 38 and the tenth servo motor 84 drives the tenth reducer 83 to rotate, and the rotating seat 36 rotates 90° in the horizontal plane to the direction perpendicular to the discharge channel or the stacking plate. The rotation direction is determined to be clockwise or counterclockwise according to the position attribute of the chip table. If the chip table belongs to the welding station on the left side of the automatic chip mechanism, it rotates counterclockwise, otherwise the chip table belongs to the welding station on the right side and rotates clockwise. After rotating in place in the horizontal plane, the eleventh servo motor 87 drives the eleventh reducer 86 to rotate the rotating seat 36 90° in the vertical plane to put the heat sink in a side-standing state.

[0077] The twelfth servo motor 89 on the automatic chip mechanism 3 drives the twelfth planetary reducer 88 to drive the tenth gear 90 to engage the third rack 34, move the sheet to the chip position, and the third servo motor 77 drives the third planetary reducer 76, and transmits torque to the first screw assembly 92 through the synchronous belt 80 to rotate, so that the first rotating support 74 connected to the lifting nut seat 95 is lowered, and the heat sink is placed on the chip table 120. The chip table 120 is driven by the ninth servo motor 118 and the ninth planetary reducer 117 drives the ninth gear 119 to engage the ninth rack 65 to move, and the stop position is determined according to the number of heat sinks required for the produced radiator. Ensure that the heat sinks are symmetrically distributed on the chip table 120 and the edgemost fixture notch is aligned with the heat sink standing on the automatic chip mechanism. After the automatic chip mechanism 3 places the heat sink on the chip table 120, it returns to the sheet picking position to complete the subsequent heat sink grabbing, rotation, feeding and other actions. After the current heat sink is placed in the chip table fixture, the chip table 120 is driven by the ninth servo motor 118 to drive the ninth planetary reducer 117 to drive the ninth gear 119 to engage the ninth rack 65 and move toward the corresponding welding station by a distance of the heat sink spacing to ensure that the sideways heat sink on the next automatic chip mechanism is aligned with the next fixture slot position.

[0078] After completing the current radiator chip, the chip table 120 is driven by the ninth servo motor 118 to drive the ninth planetary reducer 117 to drive the ninth gear 119 to engage the ninth rack 65 and move to the welding station, and the protective door on the corresponding side is closed; the protective door on the other side is opened, and the other chip table moves to the chip area to carry out the chip work for the next radiator.

[0079] During the coding process, the oil collecting pipe is manually fixed on the positioner clamp pipe beam in a certain position and direction for standby use. After the fully loaded coding table moves back to the welding station, the symmetrically distributed positioner clamped with the oil collecting pipe is driven by the fourth servo motor 42 to drive the fourth planetary reducer 43 to drive the screw 45 to rotate, so that the first positioner 4 and the second positioner 5 move toward the coding table 120. The coding table 120 is driven by the eighth servo motor 116 to drive the eighth planetary reducer 114 to drive the second screw assembly 112 to rotate and drop to the same height as the heat sink bowl and the oil collecting pipe. When the heat sink bowl fits the oil collecting pipe, the positioner and the coding table are synchronously lowered to the lowest position to facilitate manual spot welding between the heat sink bowl and the oil collecting pipe on the upper side of the body and the round steel connecting the heat sinks.

[0080] After the manual spot welding is completed, the positioner is raised to the highest position on the operation interface, and after the body of the device is automatically turned over, the positioner is lowered to the lowest position. The manual spot welding work on the other side of the body is continued.

[0081] After the spot welding work is completed, the operator clicks the spot welding completion and station ready buttons on the operation interface. At this time, the symmetrically distributed first positioner system 4 and the second positioner system 5 are synchronously raised to the highest position, the arc-proof curtain system 12 above the welding room 1 is lowered, and the working indicator light of the welding station flashes. The robot moving beam 19 on the top of the welding room 1 moves to the top of the welding station, and the inverted welding robot equipped with an extended welding gun moves to the top of the oil collecting pipe on one side, first completing the full welding of the arc weld between the bowl of the heat sink and the upper half of the oil collecting pipe in sequence, and then completing the full welding of the weld between the heat sink on this side and the outer periphery of the oil collecting pipe. After completing the weld at the oil collecting pipe on one side, the robot 28 moves to the top of the oil collecting pipe on the other side, and after completing the full welding of the weld on this side in sequence, the robot arm is retracted and moved to the waiting position. At this time, the symmetrically distributed positioner clamping beam 53 rotates 180° synchronously to complete the automatic turning over of the body. After rotating in place, the robot 28 starts from this side to complete the full welding work on this side of the radiator.

[0082] After the welding is completed, the robot 28 retracts the robot arm and moves to the waiting position, waiting for the indication signal that the welding station on the other side is ready. At the same time, the arc-proof curtain system 12 above the welding work that has completed the full welding work rises, and the symmetrically distributed first positioner system 4 and the second positioner system 5 are synchronously lowered. After the welded radiator is placed on the chip table, the chip table 120 moves out of the welding room 1 area, and the radiator is sent to a position where it can be transferred to the next process. After the radiator is transferred, the empty chip table 120 returns to the welding workstation and waits for the chip area to be ready signal.

[0083] The two welding stations are operated alternately to realize the continuous production of the radiator.

[0084] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
