Technical Field

[0001] This invention relates to the field of finned tube assembly, specifically to a finned tube assembly screw-driving device and assembly screw-driving method. Background Technology

[0002] Finned tubes are heat exchange elements. To improve heat exchange efficiency, fins are typically added to the surface of the heat exchange tube, increasing its outer surface area and thus improving efficiency.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1As shown, this application provides a first embodiment, which is a finned tube assembly screw-down device, including a frame 1 and a conveyor line 2 extending along the X direction. It also includes a support feeding assembly mechanism 3, a screw-locking station 4, a heat-shrink tubing mounting mechanism 5, a heating mechanism 6, and a performance testing mechanism 7, all sequentially arranged on the frame 1 along the conveying direction. The support feeding assembly mechanism 3 provides a head support 200 and a tail support, and assembles the head support 200 and the tail support with the finned tube 100 on the conveyor line 2. The screw-locking station 4 locks the head support 200 to the finned tube 100 and the tail support to the finned tube 100. The heat-shrink tubing mounting mechanism 5 applies heat-shrink tubing to the head support 200 or the tail support. The heating mechanism 6 heats the assembled heat-shrink tubing to shrink it. The performance testing mechanism 7 tests the performance of the assembled product.

[0031] In actual use, the finned tube 100 is conveyed by the conveyor line 2 through the bracket feeding and assembly mechanism 3, so that the bracket feeding and assembly mechanism 3 assembles the head bracket 200 at the head of the finned tube 100 and the tail bracket at the tail of the finned tube 100. Then the conveyor line 2 drives the finned tube 100 to the corresponding position of the screw fastening station 4. The screw fastening station 4 is used to fasten the head bracket 200 to the finned tube 100 and the tail bracket to the finned tube 100. Then the conveyor line 2 drives the finned tube 100 to the corresponding position of the heat shrink tubing, so that the head bracket 200 or the tail bracket is fitted with the heat shrink tubing. Then the conveyor line 2 conveys the finned tube 100 to the corresponding position of the performance testing mechanism 7, and the performance testing mechanism 7 tests the product performance.

[0032] The above design allows for the assembly of the finned tube 100 with the support, resulting in a compact structure and high working efficiency for the entire device.

[0033] Specifically: such as Figure 2 As shown, the conveyor line 2 includes a mounting base 21 set on the frame 1, a double-row conveyor chain 22 set on the mounting base 21, and a plurality of elastic carriers 23 set on the double-row conveyor chain 22. The elastic carrier 23 includes a base 231 fixed on the double-row conveyor chain 22 and elastic side plates 232 symmetrically arranged on the base 231. The elastic side plates 232 are provided with steps 233 on opposite sides for supporting the side of the finned tube 100.

[0034] In actual use, the finned tube 100 is clamped from both sides by two oppositely arranged elastic side plates 232, and the protrusions on the side of the finned tube 100 are supported by the steps 233. Then, the elastic carrier 23 is driven by the double-row conveyor chain 22 to transport the finned tube 100 along the conveying direction, thereby realizing the transport of the finned tube 100.

[0035] In the above design, the structural design and specific implementation of the conveyor line 2 can effectively realize the rapid loading and rapid conveying of the finned tube 100.

[0036] Specifically: such as Figure 3 As shown, the support feeding assembly mechanism 3 includes a vibratory plate 31, a straight vibrator 32 connected to the vibratory plate 31, a conveying pipe 33 connected to the straight vibrator 32, a pushing component 34 set on the frame 1 for pushing the support from the conveying pipe 33 to the finned tube 100, and a fixing component 35 for fixing the finned tube 100.

[0037] It should be noted that, for ease of description, the head support 200 and the tail support are collectively referred to as supports.

[0038] In actual use, the vibration is fed to the head support 200 or tail support by the vibrating plate 31 to the straight vibrator 32. The finned tube 100 is fixed by the fixing component 35, and then the support is pushed from the conveying pipe 33 onto the finned tube 100 by the pushing component 34.

[0039] In the above design, the structural design and specific implementation of the support feeding and assembly mechanism 3 can effectively realize the rapid assembly of the finned tube 100 and the support.

[0040] Specifically: such as Figure 4 As shown, the conveying pipe 33 is provided with an inlet 303 that connects to the direct vibrator 32, an outlet that connects to the finned tube 100, and a pusher port that connects to the pushing assembly 34. The pushing assembly 34 includes a first seat 341 fixedly mounted on the frame 1, a rodless cylinder 342 fixedly mounted on the first seat 341 along the Y direction, and a push rod 343 fixedly mounted on the rodless cylinder 342. The push rod 343 extends into the conveying pipe 33 through the pusher port.

[0041] In actual use, the bracket in the linear vibrator 32 enters the conveying pipe 33 from the inlet 303. At this time, the end of the finned tube 100 corresponds to the outlet. Then, the rodless cylinder 342 drives the push rod 343 to push the bracket from the conveying pipe 33 onto the finned tube 100.

[0042] In the above design, the structural design and specific implementation of the material conveying pipe 33 and the pushing component 34 can effectively realize the rapid assembly of the support and the finned tube 100.

[0043] Specifically: such as Figure 3 and Figure 4As shown, the fixing assembly 35 includes a second seat 351 mounted on the frame 1, several second cam followers A352, several second cam followers B358, a second frame 353 fixedly mounted on the second seat 351, a second cylinder 354 mounted on the upper end of the second frame 353 along the Z-axis, a connecting plate 355 located inside the second frame 353 and fixedly connected to the output end of the second cylinder 354, and second grippers A356 and B357 symmetrically hinged on both sides of the connecting plate 355. The second frame 351... 3. A second arc-shaped groove A301 and a second arc-shaped groove B302 are provided. The distance between the lower ends of the second arc-shaped groove A301 and the second arc-shaped groove B302 gradually decreases. The second gripper A356 is rolledly connected to the second arc-shaped groove A301 through the second cam follower A352. The second gripper B357 is rolledly connected to the second arc-shaped groove B302 through the second cam follower B358. The second cylinder 354 drives the connecting plate 355 to move downward, causing the second gripper B357 and the second gripper A356 to move towards each other.

[0044] In actual use, before the finned tube 100 moves to the corresponding position of the fixing component 35, the output end of the second cylinder 354 is in a retracted state. When the finned tube 100 moves to stop between the second clamping jaw A356 and the second clamping jaw B357, the output end of the second cylinder 354 moves down, causing the second clamping jaw A356 to move down along the second arc groove A301 through the second cam follower A352, and the second clamping jaw B357 to move down along the second arc groove B302 through the second cam follower B358. This causes the lower ends of the second clamping jaw A356 and the second clamping jaw B357 to retract relative to each other, thereby clamping and fixing the finned tube 100 from both sides.

[0045] In the above design, the structural design of the fixing component 35 enables the clamping of the finned tube 100 while saving the vertical lifting component. Thus, the lifting and opening / closing of the second gripper A356 and the second gripper B357 can be simultaneously achieved using only the second cylinder 354, realizing both the avoidance of movement of the finned tube 100 and the clamping and fixing of the finned tube 100 after it stops. This effectively saves costs.

[0046] Specifically: such as Figure 1 and Figure 5As shown, the screw fastening station 4 includes a head screw fastening mechanism 41 and a tail screw fastening mechanism 42 respectively disposed on both sides of the conveyor line 2. The head screw fastening mechanism 41 includes a No. 3 seat A411, a No. 3 linear module 412 fixedly disposed on the frame 1 for driving the No. 3 seat A411 to move in the Y direction, a head fixing member 413 disposed on the No. 3 seat A411 for clamping the head support 200, and a screw fastening machine A414 disposed on the No. 3 seat A411. The tail screw fastening mechanism 42 includes a No. 3 seat B421 fixedly disposed on the frame 1, a tail fixing member 422 disposed on the No. 3 seat B421 for clamping the tail support, and a screw fastening machine B423 disposed on the No. 3 seat B421. The screw fastening machine A414 and the screw fastening machine B423 have the same structure. The screw fastening machine A414 includes a Y-axis drive module fixedly mounted on the No. 3 base, a Z-axis drive module fixedly mounted on the output end of the Y-axis drive module, and a screw fastening machine mounted on the output end of the Z-axis drive module. like Figure 6 and Figure 7 As shown, the head fixing member 413 includes a third cylinder A4131 fixedly mounted on the third seat A411 along the Y direction, a third gripper A4132 fixedly mounted on the output end of the third cylinder A4131, a fourth cylinder A4133 fixedly mounted on the upper end of the third cylinder A4131 along the Y direction, and an abutment seat A4134 fixedly mounted on the output end of the fourth cylinder A4133. The tail fixing member 422 includes a third cylinder B4221 fixedly mounted on the third seat B421, a third gripper B4222 fixedly mounted on the output end of the third cylinder B4221, and an abutment seat B4223 fixedly mounted on the third seat B421. The third gripper A4132 and the third gripper B4222 have the same structure.

[0047] In actual use, the head screw-locking mechanism 41 is used to screw the head bracket 200 and the finned tube 100, and the tail screw-locking mechanism 42 is used to screw the tail bracket and the finned tube 100. The working principle is as follows: the third linear module 412 drives the third seat A411 to move towards the tail screw-locking mechanism 42, causing the head bracket 200 mounted on the finned tube 100 to abut against the abutment seat A4134, and the tail bracket mounted on the finned tube 100 to abut against the abutment seat B4223. Then, the third cylinder A4131 drives the third gripper A4132 to fix the head bracket 200, and the third cylinder B4221 drives the third gripper B4222 to fix the tail bracket, thus fixing the head bracket 200 and the tail bracket in the Y direction. Subsequently, the Y-axis drive module and the Z-axis drive module drive the screw-driving machine to fasten the bracket and the finned tube 100.

[0048] In the above design, the structural design and specific implementation of the screw-locking station 4 can effectively achieve rapid fastening of the bracket and the finned tube 100.

[0049] Specifically: such as Figure 6 As shown, the No. 3 gripper A4132 and the No. 3 gripper B4222 have the same structure. The No. 3 gripper A4132 includes a No. 3 frame 1321 fixedly mounted on the No. 3 seat A411, several No. 3 cam followers 1322, and claw toes connected to the output end of the No. 3 cylinder A4131. The No. 3 frame 1321 has corresponding No. 3 sliding grooves on both sides. One end of the No. 3 cam follower 1322 is fixedly connected to the claw toes, and the other end of the No. 3 cam follower 1322 is tumbling connected to the sliding groove. The No. 3 sliding groove includes a horizontal groove 101 and an inclined groove 102. The end of the inclined groove 102 is lower than the horizontal groove 101. The claw toes include a body 1323 and an L-shaped barb 1324 mounted on the body 1323. The body 1323 is connected to the output end of the No. 3 cylinder A4131.

[0050] In actual use, when the finned tube 100 moves to the position corresponding to the third gripper A4132, the output end of the third cylinder A4131 extends, so that the outermost third cam follower 1322 is located at the end of the inclined slide groove 102, and the L-shaped barb 1324 is located below the lower end of the fin. When the finned tube 100 stops, the output end of the third cylinder A4131 retracts, so that the third cylinder A4131 drives the claw to move to the side of the horizontal groove 101 through the third cam follower 1322, so that the L-shaped barb 1324 flips and abuts against the end of the bracket, so that the two ends of the bracket abut against the abutment seat A4134 and the L-shaped barb 1324 respectively.

[0051] In the above design, the structural design and specific implementation of the No. 3 gripper A4132 can effectively fix the bracket.

[0052] Specifically: such as Figure 1 and Figure 8 As shown, the upper heat shrink tubing mechanism 5 is a manual workstation, and the heating mechanism 6 is equipped with a heating channel 61 and a heater 62 located above the heating channel 61. The end of the finned tube 100 can automatically enter the heating channel 61 along with the conveyor line 2.

[0053] In actual use, when the finned tube 100 moves to the upper heat shrink tubing mechanism 5, the heat shrink tubing is manually placed on the bracket. Then, the conveyor line 2 drives the finned tube 100 through the heating pipe. After being heated by the heater 62, the heat shrink tubing shrinks and adheres tightly to the bracket.

[0054] In the above design, the structural design and specific implementation of the upper heat shrink tubing mechanism 5 and the heating mechanism 6 can fix the heat shrink tubing on the bracket.

[0055] Specifically: such as Figure 9 and Figure 10 As shown, the performance testing mechanism 7 includes a conductive busbar assembly 71 mounted on the frame 1, a defective product lifting assembly 72, a conveyor chain 73 mounted on the frame 1, several carriers 74 mounted on the conveyor chain 73, and live plugs 75 mounted on the carriers 74. The conductive bus assembly 71 includes a mounting plate 711 fixedly mounted on the frame 1, an insulating seat 712 mounted on the mounting plate 711, a conductive copper block 713 hinged to the insulating seat 712, and a torsion spring mounted between the insulating seat 712 and the conductive copper block 713. The defective product lifting assembly 72 includes a No. 5 cylinder 721 arranged along the Z direction on the frame 1, a lifting plate 722 fixedly arranged at the output end of the No. 5 cylinder 721, and a push block 723 fixedly arranged on the lifting plate 722. The defective product lifting component 72 and the conductive busbar component 71 are horizontally aligned.

[0056] In actual use, when the conveyor line 2 moves the finned tube 100, the finned tube 100 passes through the conductive busbar assembly 71, causing the finned tube 100 to press down on the conductive copper block 713 to connect to electricity. Then, by inserting the live plug 75 into the head connector, a withstand voltage test or a continuity test is performed. When the test fails, the lifting plate 722 is driven by the No. 5 cylinder 721 to drive the push block 723 to lift, pushing the defective product out of the conveyor line 2.

[0057] In the above design, the structural design and specific implementation of the performance testing mechanism 7 facilitate the testing of the product.

[0058] This application provides a second embodiment, which is a method for assembling and screwing finned tubes 100. The method employs a finned tube 100 assembly and screwing device. In actual use, the finned tubes 100 are conveyed sequentially through the support feeding assembly mechanism 3 via the conveyor line 2. The support feeding assembly mechanism 3 assembles a head support 200 at the head of the finned tube 100 and a tail support at the tail. Then, the conveyor line 2 moves the finned tube 100 to the corresponding position of the screw-locking station 4. The screw-locking station 4 locks the head support 200 and the tail support to the finned tube 100. Subsequently, the conveyor line 2 drives the finned tube 100 to the corresponding position of the heat-shrink tubing, allowing the heat-shrink tubing to be fitted onto the head support 200 or the tail support. Finally, the conveyor line 2 moves the finned tube 100 to the corresponding position of the performance testing mechanism 7, where the product performance is tested.

[0059] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
