[0037] like Figure 1As shown, the present application provides a first embodiment, which is a fin tube assembly screwing device, including a frame 1 and a conveyor line 2 extending along the X direction, and also including a bracket feeding assembly mechanism 3, a screw locking station 4, an upper heat shrink sleeve mechanism 5, a heating mechanism 6 and a performance detection mechanism 7 which are sequentially arranged on the frame 1 along the conveying direction, the bracket feeding assembly mechanism 3 is used to provide a head bracket 200 and a tail bracket and assemble the head bracket 200 and the tail bracket with the fin tube 100 on the conveyor line 2, the screw locking station 4 is used to lock the head bracket 200 with the fin tube 100, and the tail bracket with the fin tube 100, the upper heat shrink sleeve mechanism 5 is used to put a heat shrink sleeve on the head bracket 200 or the tail bracket, the heating mechanism 6 is used to heat the assembled heat shrink sleeve to shrink it, and the performance detection mechanism 7 is used to detect the performance of the assembled product.

[0038] In actual use, the fin tube 100 is conveyed by the conveyor line 2 and passes through the bracket feeding assembly mechanism 3 in sequence, so that the bracket feeding assembly mechanism 3 assembles the head bracket 200 for the head of the fin tube 100 and assembles the tail bracket for the tail of the fin tube 100, and then the conveyor line 2 drives the fin tube 100 to move to the corresponding position of the screw locking station 4, and the head bracket 200 and the fin tube 100, the tail bracket and the fin tube 100 are locked by the screw locking station 4, and then the fin tube 100 is driven by the conveyor line 2 to move to the corresponding position of the upper heat shrink sleeve, so that the head bracket 200 or the tail bracket is covered with the heat shrink sleeve; then the conveyor line 2 conveys the fin tube 100 to move to the corresponding position of the performance testing mechanism 7, and the product performance is tested by the performance testing mechanism 7.

[0039] In the above design, the fin tube 100 and the bracket can be assembled, and the entire device is not only compact in structure but also has high working efficiency.

[0040] Specifically: Figure 2 As shown, the conveyor line 2 includes a mounting base 21 arranged on the frame 1, a double-row conveyor chain 22 arranged on the mounting base 21, and a plurality of elastic carriers 23 arranged on the double-row conveyor chains 22. The elastic carrier 23 includes a base 231 with a fixing frame arranged on the double-row conveyor chain 22, and an elastic side plate 232 symmetrically arranged on the base 231. The opposite side of the elastic side plate 232 is provided with a step 233 for supporting the side of the fin tube 100.

[0041] In actual use, the fin tube 100 is clamped from both sides of the fin tube 100 by two oppositely arranged elastic side plates 232, and the protrusions on the side of the fin tube 100 are supported by the steps 233. Then, the elastic support 23 is driven by the double-row conveyor chain 22 to convey along the conveying direction, thereby realizing the conveying of the fin tube 100.

[0042] In the above design, the structural design and specific implementation of the conveyor line 2 can effectively realize the rapid loading and rapid conveyance of the fin tube 100 .

[0043] Specifically: Figure 3 As shown, the bracket feeding assembly mechanism 3 includes a vibration plate 31, a straight vibrator 32 docked with the vibration plate 31, a material conveying pipeline 33 docked with the straight vibrator 32, a pushing component 34 arranged on the frame 1 for pushing the bracket from the material conveying pipeline 33 to the fin tube 100, and a fixing component 35 for fixing the fin tube 100.

[0044] When necessary, for ease of description, the head bracket 200 and the tail bracket are collectively referred to as brackets.

[0045] In actual use, the head bracket 200 or the tail bracket is vibrated in the straight vibrator 32 through the vibration plate 31, the fin tube 100 is fixed by the fixing assembly 35, and then the bracket is pushed from the material conveying pipeline 33 to the fin tube 100 by the pushing assembly 34.

[0046] In the above design, the structural design and specific implementation of the support feeding assembly mechanism 3 can effectively realize the rapid assembly of the fin tube 100 and the support.

[0047] Specifically: Figure 4 As shown, the material delivery pipeline 33 is provided with an inlet 303 connected to the straight vibrator 32, an outlet connected to the fin tube 100 and a push port connected to the pushing assembly 34, and the pushing assembly 34 includes a No. 1 seat 341 fixedly arranged on the frame 1, a rodless cylinder 342 fixedly arranged on the No. 1 seat 341 along the Y direction, and a push rod 343 fixedly arranged on the rodless cylinder 342, and the push rod 343 extends into the material delivery pipeline 33 through the push port.

[0048] In actual use, the bracket in the straight vibrator 32 enters the feed pipe 33 from the feed inlet 303, at which time the end of the fin tube 100 corresponds to the discharge port, and then the rodless cylinder 342 drives the push rod 343 to push the bracket from the feed pipe 33 to the fin tube 100.

[0049] In the above design, the structural design and specific implementation of the material conveying pipeline 33 and the pushing assembly 34 can effectively realize the rapid assembly of the bracket and the fin tube 100.

[0050] Specifically: Figure 3 and Figure 4As shown, the fixing assembly 35 includes a No. 2 seat 351 arranged on the frame 1, a plurality of No. 2 cam followers A352, a plurality of No. 2 cam followers B358, a No. 2 frame 353 fixedly arranged on the No. 2 seat 351, a No. 2 cylinder 354 arranged at the upper end of the No. 2 frame 353 along the Z-axis direction, a connecting plate 355 located in the No. 2 frame 353 and fixedly connected to the output end of the No. 2 cylinder 354, and a No. 2 clamping jaw A356 and a No. 2 clamping jaw B357 symmetrically hinged on both sides of the connecting plate 355. A second arc groove A301 and a second arc groove B302 are provided, the lower end spacing of the second arc groove A301 and the second arc groove B302 is gradually reduced, the second clamping jaw A356 is rollingly connected with the second arc groove A301 through the second cam follower A352, the second clamping jaw B357 is rollingly connected with the second arc groove B302 through the second cam follower B358, and the second cylinder 354 drives the connecting plate 355 to move downward to drive the second clamping jaw B357 and the second clamping jaw A356 to move toward each other.

[0051] In actual use, before the fin tube 100 moves to the corresponding position of the fixing assembly 35, the output end of the No. 2 cylinder 354 is in a retracted state. When the fin tube 100 moves to and stops between the No. 2 clamp A356 and the No. 2 clamp B357, the output end of the No. 2 cylinder 354 then moves downward, so that the No. 2 clamp A356 moves downward along the No. 2 arc groove A301 through the No. 2 cam follower A352, and the No. 2 clamp B357 moves downward along the No. 2 arc groove B302 through the No. 2 cam follower B358, so that the lower ends of the No. 2 clamp A356 and the No. 2 clamp B357 shrink relatively, thereby clamping and fixing the fin tube 100 from both sides.

[0052] In the above design, the structural design of the fixing assembly 35 can realize the clamping of the fin tube 100, and can also save the vertical lifting assembly, so that the lifting and opening and closing of the second clamping jaw A356 and the second clamping jaw B357 can be realized only by the second cylinder 354, so as to realize the avoidance of the movement of the fin tube 100 and the clamping and fixing of the fin tube 100 after stopping, which effectively saves costs.

[0053] Specifically: Figure 1 and Figure 5As shown, the screw locking station 4 includes a head screw locking mechanism 41 and a tail screw locking mechanism 42 respectively arranged on both sides of the conveyor line 2, the head screw locking mechanism 41 includes a No. 3 seat A411, a No. 3 linear module 412 fixedly arranged on the frame 1 for driving the No. 3 seat A411 to move along the Y direction, a head fixing member 413 arranged on the No. 3 seat A411 for clamping the head bracket 200, and a screw locking machine A414 arranged on the No. 3 seat A411, the tail screw locking mechanism 42 includes a No. 3 seat B421 fixedly arranged on the frame 1, a tail fixing member 422 arranged on the No. 3 seat B421 for clamping the tail bracket, and a screw locking machine B423 arranged on the No. 3 seat B421, and the screw locking machine A414 and the screw locking machine B423 have the same structure.

[0056] In actual use, the head bracket 200 and the fin tube 100 are screwed by the head screw locking mechanism 41, and the tail bracket and the fin tube 100 are screwed by the tail screw locking mechanism 42. The working principle is: the No. 3 linear module 412 drives the No. 3 seat A411 to move to the side of the tail screw locking mechanism 42, so that the head bracket 200 installed on the fin tube 100 is abutted against the abutment seat A4134, and the tail bracket installed on the fin tube 100 is abutted against the abutment seat B4223. Then, the No. 3 cylinder A4131 drives the No. 3 clamp A4132 to fix the head bracket 200, and the No. 3 cylinder B4221 drives the No. 3 clamp B4222 to fix the tail bracket, so that the head bracket 200 and the tail bracket are fixed in the Y direction, and then the Y-axis drive module and the Z-axis drive module drive the screw driver to lock the bracket and the fin tube 100.

[0057] In the above design, the structural design and specific implementation method of the screw locking station 4 can effectively realize the rapid locking of the bracket and the fin tube 100 .

[0059] In actual use, when the fin tube 100 moves to the corresponding position of the No. 3 clamp A4132, the output end of the No. 3 cylinder A4131 extends, so that the outermost No. 3 cam follower 1322 is located at the end of the inclined slide groove 102, so that the L-shaped barb 1324 is located below the lower end of the fin end; when the fin tube 100 stops, the output end of the No. 3 cylinder A4131 contracts, so that the No. 3 cylinder A4131 drives the claw toe to move toward the side of the horizontal groove 101 through the No. 3 cam follower 1322, so that the L-shaped barb 1324 flips over and abuts against the end of the bracket, so that the two ends of the bracket respectively abut against the abutment seat A4134 and the L-shaped barb 1324.

[0060] In the above design, the structural design and specific implementation method of the No. 3 clamp A4132 can effectively fix the bracket.

[0062] In actual use, when the fin tube 100 moves to the upper heat shrink sleeve mechanism 5, the heat shrink sleeve is manually put on the bracket, and then the conveyor line 2 drives the fin tube 100 through the heating pipe. After being heated by the heater 62, the heat shrink sleeve shrinks and fits tightly on the bracket.

[0063] In the above design, the structural design and specific implementation of the upper heat shrinkable tube mechanism 5 and the heating mechanism 6 can fix the heat shrinkable tube on the bracket.

[0068] In actual use, when the conveyor line 2 drives the fin tube 100 to move, the fin tube 100 passes through the conductive row assembly 71, so that the fin tube 100 presses down the conductive copper block 713 to connect electricity, and then inserts the live plug 75 into the head joint to perform a withstand voltage test or a continuity test. If the test fails, the No. 5 cylinder 721 drives the lifting plate 722 to drive the push block 723 to lift, and the defective product is ejected from the conveyor line 2.
