Description

Technical Field

[0001] The present invention relates to the field of fan assembly machines, and in particular to a copper middle tube fan assembly line. Background Art

[0002] The middle tube of the fan frame made of copper has better durability. To assemble the fan, it is necessary to perform the following procedures in sequence: feeding the fan frame, applying glue to the fan frame, assembling the stator, detecting the press-fitting height of the stator, testing the insulation of the fan frame, applying oil to the middle tube, assembling the gasket, visually detecting the gasket assembly, assembling the snap ring, visually detecting the snap ring assembly, assembling the bearing, assembling the retaining ring or snap ring, detecting the retaining ring or snap ring, thermally melting and fixing the bearing on the middle tube, applying oil to the middle tube again, visually detecting the retaining ring or snap ring assembly and the amount of oil applied, assembling the fan blade and detecting the assembling height of the fan blade, turning over and transferring the finished fan, attaching labels to the fan, and conveying the finished fan for blanking, etc. The procedures are complex and the installation accuracy requirements are high. Most of the existing fan assembly machines on the market cannot complete the procedures such as detecting the press-fitting height of the stator, testing the insulation of the fan frame, thermally melting the copper middle tube, detecting the assembling height of the fan blade, and attaching labels to the fan on the same machine or the same device. As a result, the above-mentioned fan assembly procedures need to be carried out on different machines or different devices, and the assembled fan frame needs to be transferred between two adjacent different procedures, which results in disadvantages such as poor versatility, long assembly cycle, low assembly efficiency, low assembly accuracy, high purchase cost for enterprises, and large floor area or occupied space of the device. In addition, the existing fan assembly machines on the market also have the following deficiencies: 1. It is impossible to freely choose to install a retaining ring or snap ring (i.e., a copper retaining ring or an iron retaining ring) on the same device according to different requirements of fan assembly; 2. Only partial glue can be applied to the fan frame, resulting in insecure stator assembly; 3. The insulation testing mechanism can only perform tests from a single direction, resulting in poor testing accuracy and poor versatility, and the traditional insulation testing table affects the conveying efficiency and conveying accuracy of the fan frame because it cannot be adjusted to the same horizontal height as other conveying lines. Therefore, it is necessary to develop a copper middle tube fan assembly line to automatically complete multiple different assembly procedures such as detecting the press-fitting height of the stator, testing the insulation of the fan frame, thermally melting the copper middle tube, detecting the assembling height of the fan blade, and attaching labels to the fan on one assembly line, and at the same time, it can meet the requirement of installing a retaining ring or snap ring as needed according to different assembly requirements. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a copper middle tube fan assembly line.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The copper middle tube fan assembly line includes a table board, on the edge of which are successively and annularly arranged a first mounting rack, a second mounting rack, a third mounting rack, a fourth mounting rack, a fifth mounting rack, a sixth mounting rack and a seventh mounting rack.

Below the finished product transplanting mechanism is a finished product flipping mechanism; Outside the discharging end of the annular track conveying line is a finished product conveying line. On one side of the finished product conveying line is a labeling mechanism. Between the labeling mechanism and the finished product conveying line is a sixth vision detection component.

Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0064] Referring to Figures 1 to 3 As shown, the copper tube fan assembly line of the present invention includes a table board 1. First mounting frames 21, second mounting frames 22, third mounting frames 23, fourth mounting frames 24, fifth mounting frames 25, sixth mounting frames 26, and seventh mounting frames 27 are sequentially arranged in a circular distribution on the edge of the table board 1. A first fan frame transplanting mechanism 31 and a first vision detection component 41 are mounted on the first mounting frame 21. A fan frame rotating mechanism 5 for rotating the fan frame is provided below the first fan frame transplanting mechanism 31.

The first fan frame transplanting mechanism 31 clamps the fan frames from the first fan frame conveying line 81 and transfers the fan frames to the fan frame rotating mechanism 5. The fan frame rotating mechanism 5 rotates the fan frames. The fan frame dispensing mechanism 6 dispenses glue on the fan frames. The first vision detection component 41 performs vision detection on the glue dispensing conditions on the fan frames. After the glue dispensing is completed, the first fan frame transplanting mechanism 31 transfers the fan frames after glue dispensing to the second fan frame conveying line 82. At the same time, the first fan frame transplanting mechanism 31 clamps the next fan frame from the first fan frame conveying line 81 and transfers the fan frame to the fan frame rotating mechanism 5 for feeding and transferring before the next fan frame glue dispensing. It has the advantages of high feeding efficiency, good glue dispensing effect, and high detection accuracy for the fan frames.

[0066] Referring to Figures 1 to 2As shown in the figure, a stator picking and placing mechanism 9, a stator pressing mechanism 10, and a stator height detection mechanism 11 are successively arranged on the second mounting frame 22 along the transplanting direction of the fan frame. A second fan frame transplanting mechanism 32 is arranged inside the second mounting frame 22, and the second fan frame transplanting mechanism 32 is mounted on the table board 1. A fourth fan frame conveying line 84 is arranged on one side of the second fan frame transplanting mechanism 32, and a third fan frame conveying line 83 is arranged between the same end of the second fan frame transplanting mechanism 32 and the fourth fan frame conveying line 84.

[0067] By adopting the above technical solution, the stator picking and placing mechanism 9 picks up the stator from the stator conveying line 7 and places the stator on the second fan frame transplanting mechanism 32. The second fan frame transplanting mechanism 32 successively transplants the stator to the corresponding workstations. The stator pressing mechanism 10 presses the stator onto the fan frame transplanted below it. The stator height detection mechanism 11 detects the height of the stator transplanted below it to detect whether the stator is pressed in place. The third fan frame conveying line 83 receives the fan frame with the stator transferred from the second fan frame transplanting mechanism 32 and transfers it to the fourth fan frame conveying line 84. The fourth fan frame conveying line 84 conveys the fan frame with the stator.

An insulation testing mechanism 12 is arranged below the third fan frame transplanting mechanism 33. An annular track conveying line 13 for circulating and conveying the fan frame fixture 1310 is arranged on the same side of the third mounting frame 23, the fourth mounting frame 24, the fifth mounting frame 25, the sixth mounting frame 26, and the seventh mounting frame 27.

[0069] By adopting the above technical solution, the third fan frame transplanting mechanism 33 picks up the fan frame with the stator from the fourth fan frame conveying line 84 and places it on the insulation testing mechanism 12. The insulation testing mechanism 12 conducts an insulation test on the fan frame with the stator. The third fan frame transplanting mechanism 33 picks up the fan frame with the stator after insulation testing from the insulation testing mechanism 12 and transfers it to the annular track conveying line 13. At the same time, the third fan frame transplanting mechanism 33 picks up the next fan frame with the stator from the fourth fan frame conveying line 84 and places it on the insulation testing mechanism 12. It fully automatically completes the transplanting and insulation testing of the fan frame with the stator, and has the advantages of high transplanting efficiency, high insulation testing efficiency, good insulation testing effect, and high testing accuracy.

The iron pressing ring transfer and assembly mechanism 19 performs iron pressing ring loading and transfer and assembles iron pressing rings onto the bearings in the middle tubes of the corresponding fan frames on the annular track conveyor line 13. Since the copper pressing ring transfer and assembly mechanism 18 and the iron pressing ring transfer and assembly mechanism 19 respectively provide copper pressing rings and iron pressing rings, it can choose the copper pressing ring transfer and assembly mechanism 18 to assemble copper pressing rings or choose the iron pressing ring transfer and assembly mechanism 19 to assemble iron pressing rings according to different assembly needs.

It not only has the advantages of high assembly efficiency, good assembly effect, high assembly accuracy and convenient use, but also integrates the assembly of copper pressing rings and iron pressing rings on the same device.

The fan blade transfer and assembly mechanism 28 assembles fan blades onto the bearings in the middle tubes of the corresponding fan frames on the annular track conveyor line 13. The snap ring under the bearings in the middle tubes snaps and installs the fan blades. The fan blade height detection mechanism 29 detects the height of the corresponding fan blades on the annular track conveyor line 13 to determine whether the fan blades are properly installed on the bearings. After the assembly of the fan blades is detected by the fan blade height detection mechanism 29, it becomes a finished fan. It realizes the full automation of hot melting and fixing bearings in the middle tubes, oiling, fan blade assembly and fan blade height detection, and has the advantages of high assembly efficiency, high assembly accuracy, good assembly effect and high detection accuracy.

The stator conveyor belt line 73 drives the stator 77 to move forward on the stator transplanting plate 74 through the stator fixture 75 to provide the stator 77 for the stator picking and placing mechanism 9; the stator lifting drive device 711 drives the stator lifting support 714 to lower to drive the stator conveyor belt line 73 to lower, so that the stator fixture 75 is separated from the stator on the stator transplanting plate 74. The stator conveyor belt line 73 rotates freely without driving the stator to move forward. The frontmost stator 77 placed on the stator transplanting plate 74 waits to be taken away. The cooperation between the stator conveyor line 7 and the lifting mechanism 71 not only realizes the full-automatic conveyance and positioning of the stator 77, but also enables the stator 77 to be conveyed orderly one by one in the same direction and along the same straight path. It has the advantages of smooth conveyance, high conveyance efficiency, and good positioning effect, thus solving the problem that the conventional conveyor belt of the existing fan assembly machine for conveying the stator is prone to deviation or dumping during the conveyance process, resulting in the inability to convey the stator in an orderly manner in the same direction, and thus the need to add a process of judging the head and tail directions of the stator and a structure for correcting the deviation and positioning of the stator before installing the stator, thereby increasing the complexity of the process and the cost. In this embodiment, the stator lifting drive device 711 is set as a cylinder.

The second fan frame longitudinal moving assembly 326 includes at least two vertical linear guide rails and a cylinder. The fan frame conveying bracket 327 is slidably installed on the at least two vertical linear guide rails.

[0090] By adopting the above technical solution, the fan frame transplanting jig 320 positions the fan frame 54, the gasket column 322 supports the transplanting jig bracket 321 to cooperate with the stator pressing mechanism 10 and the stator height detection mechanism 11 to press the stator on the fan frame 54 and test the stator assembly respectively, the third fan frame clamping assembly 328 and several fourth fan frame clamping assemblies 329 clamp the fan frame respectively, the second fan frame transverse moving assembly 324 and the second fan frame longitudinal moving assembly 326 jointly drive the third fan frame clamping assembly 328 and several fourth fan frame clamping assemblies 329 to transplant the fan frame.

[0091] Reference Figure 11As shown, the stator loading and unloading mechanism 9 includes a stator longitudinal movement component 91, a stator transverse transfer component 92, a stator clamping and mounting plate 93, a stator clamping component 94, a stator positioning rod 95, and a stator pressing plate 96.

The stator longitudinal movement component 91 and the stator transverse transfer component 92 cooperate to drive the stator clamping component 94 to clamp the stator from the stator conveying line 7 and place it on the corresponding fan frame in the first fan frame transplanting mechanism 31 for installation. When the stator longitudinal movement component 91 drives the stator positioning rod 95 to pre-press the stator onto the fan frame, the automatic assembly of the stator to the fan frame is completed. In this embodiment, the stator clamping arm opening and closing driving device 941 is set as a clamping cylinder.

[0092] Referring to Figure 12 As shown, the stator pressing mechanism 10 includes a stator punch longitudinal movement component 101 installed on the second mounting frame 22. A stator punch mounting plate 102 is installed on the longitudinal moving end of the stator punch longitudinal movement component 101. A stator punch pressure sensor 103 is installed on the bottom surface of the stator punch mounting plate 102, and a stator punch 104 is installed on the bottom surface of the stator punch pressure sensor 103. The stator punch longitudinal movement component 101 drives the stator punch 104 and the stator punch pressure sensor 103 to descend. The stator punch 104 presses the stator onto the fan frame, and the stator punch pressure sensor 103 detects the pressure magnitude of the stator pressing to ensure that the stator is pressed tightly on the fan frame and installed in place.

[0093] Referring to Figure 13As shown in the figure, the stator height detection mechanism 11 includes a detection rod longitudinal movement component 110 installed on the second mounting bracket 22. A detection rod mounting plate 111 is installed on the longitudinal movement part of the detection rod longitudinal movement component 110. A detection rod telescopic seat 112 is installed on the bottom surface of the detection rod mounting plate 111.

The upper end of the detection rod 113 is connected with a displacement sensor 114, and the displacement sensor 114 is installed on the top surface of the detection rod mounting plate 111. The detection rod longitudinal movement component 110 drives the detection rod 113 to descend to the upper surface of the stator, and the displacement sensor 114 monitors whether the displacement distance of the detection rod 113 is the same as the predetermined displacement distance to judge whether the stator is pressed in place, ensuring accurate detection of the stator being pressed in place.

[0094] By adopting the above technical solution, several fan frame transplanting jigs 320 in the second fan frame transplanting mechanism 32 sequentially perform positioning and cooperation on the fan frames to receive the stator, press the stator, and detect whether the stator is pressed in place. The stator picking and placing mechanism 9 picks the frontmost fan frame from the second fan frame conveying line 82 and transfers it to the corresponding fan frame transplanting jig 320 on the second fan frame transplanting mechanism 32 for positioning. The stator pressing mechanism 10 presses the corresponding stator on the second fan frame transplanting mechanism 32. The stator height detection mechanism 11 performs height detection on the corresponding stator on the second fan frame transplanting mechanism 32 to judge whether it is pressed in place. At the same time, the second fan frame transverse movement component 324 and the second fan frame longitudinal movement component 326 of the second fan frame transplanting mechanism 32 jointly drive several fourth fan frame clamping components 329 to pick the fan frames from the previous fan frame transplanting jig 320 in sequence and transfer them to the adjacent fan frame transplanting jig 320 for positioning to cooperate in receiving the stator, pressing the stator, and detecting whether the stator is pressed in place. Finally, the fan frame with the stator is transferred to the third fan frame conveying line 83, and the third fan frame conveying line 83 transfers the fan frame to the fourth fan frame conveying line 84. It realizes fully automatic operations such as fan frame transplanting, stator installation and feeding and conveying, stator pressing, and stator pressing in place detection, and has the advantages of high stator assembly test accuracy, high stator assembly efficiency, and good stator assembly effect. The cooperation of the stator picking and placing mechanism 9, the stator pressing mechanism 10, and the stator height detection mechanism 11 solves the problems of poor stator assembly effect and low stator assembly good product rate of the traditional fan assembly machine due to the lack of stator pressure detection and the lack of a structure for detecting whether the stator is pressed in place, resulting in its inability to complete the pressing height detection of the stator on the same assembly machine.

[0095] Refer to Figure 14 and Figure 15As shown in the figure, the insulation testing mechanism 12 includes an insulation testing base 120, a number of buffer guide rods 121, an insulation testing table 122, an insulation testing fixture 123, a three-dimensional fine-tuning slide table II 124, a thimble mounting block 125, a middle tube thimble 126, and a number of stator contact thimbles 127. The insulation testing base 120 is installed on the table board 1. The insulation testing table 122 is installed on the insulation testing base 120 through a number of buffer guide rods 121 in a liftable and bufferable manner. The insulation testing table 122 is provided with an insulation testing hole 128. The insulation testing fixture 123 is installed on the insulation testing table 122 and located above the insulation testing hole 128. The three-dimensional fine-tuning slide table II 124 is installed on the insulation testing base 120. The thimble mounting block 125 is installed on the three-dimensional fine-tuning slide table II 124. The middle tube thimble 126 and a number of stator contact thimbles 127 are longitudinally installed on the thimble mounting block 125.

[0096] By adopting the above technical solution, since the insulation testing table 122 is not on the same horizontal plane as the fourth fan frame conveyor line 84 and the circular track conveyor line 13 respectively, when clamping or placing the fan frame on the insulation testing table 122, it is necessary to lower the insulation testing table 122 to the same height as the fourth fan frame conveyor line 84 and the circular track conveyor line 13 to facilitate the transfer and conveyance of the fan frame. The buffer guide rods 121 play a buffering role in the lifting and lowering of the insulation testing table 122. After the insulation testing table 122 is lowered, the middle tube thimble 126 and a number of stator contact thimbles 127 pass through the insulation testing hole 128 and contact the middle tube and stator contacts in the fan frame respectively for insulation testing. The three-dimensional fine-tuning slide table II 124 performs three-dimensional spatial positioning adjustment on the middle tube thimble 126 and a number of stator contact thimbles 127 so that the middle tube thimble 126 and a number of stator contact thimbles 127 can accurately contact the middle tube and stator contacts for insulation detection. It also enables the middle tube thimble 126 and a number of stator contact thimbles 127 to perform insulation detection on the middle tube and stator contacts from any angle in three-dimensional space, so as to overcome the problems of poor testing effect, low testing accuracy, and poor versatility caused by the traditional insulation testing mechanism that can only test workpieces from a single direction (such as vertically). In addition, the structural design of the insulation testing mechanism 12 also solves the problem that the insulation testing table 122 is not on the same horizontal plane as the fourth fan frame conveyor line 84 and the circular track conveyor line 13, which affects the transfer efficiency and transfer accuracy of the fan frame. It improves the transfer speed of the fan frame between two adjacent workstations to improve the testing efficiency and testing accuracy.

The sash frame height positioning rod 336 is installed on the positioning rod mounting plate 337. The first laser sensor 338 is fixed to the third mounting frame 23 through the first laser sensor bracket 339.

[0098] By adopting the above technical solution, the third frame transverse movement component 331 and the third frame longitudinal movement component 332 of the third frame transplanting mechanism 33 jointly drive the sixth frame clamping component 335 to clamp a frame from the fourth frame conveying line 84. At the same time, the frame height positioning rod 336 presses down the insulation test fixture 123 so that the insulation test bench 122 and the fourth frame conveying line 84 are on the same horizontal plane to adapt to the sixth frame clamping component 335 to transfer the frame between the fourth frame conveying line 84 and the insulation test mechanism 12. The frame is transferred and placed on the insulation test bench 122, and at the same time, the insulation test mechanism 12 performs an insulation test on the frame. After the test is completed, the sixth frame clamping component 335 releases the frame that has completed the insulation test. The third frame transverse movement component 331 and the third frame longitudinal movement component 332 jointly drive the frame height positioning rod 336 of the fifth frame clamping component 334 to press down the insulation test fixture 123 so that the insulation test bench 122 and the top of the annular track conveying line 13 are on the same horizontal plane to adapt to the fifth frame clamping component 334 to transfer the frame between the insulation test mechanism 12 and the annular track conveying line 13. The fifth frame clamping component 334 clamps the frame after insulation test from the insulation test fixture 123. At the same time, the sixth frame clamping component 335 clamps the next frame from the fourth frame conveying line 84. The third frame transverse movement component 331 and the third frame longitudinal movement component 332 jointly drive the fifth frame clamping component 334 and the sixth frame clamping component 335 to place their respective frames on the annular track conveying line 13 and the insulation test mechanism 12 respectively. It realizes automatic frame transplanting and presses down the insulation test fixture 123 to adapt to frame transplanting and conveying of the annular track conveying line 13, the insulation test bench 122 and the fourth frame conveying line 84 at different heights, thereby improving the conveying efficiency and ensuring good conveying effect.

The peristaltic dispensing pen 130 is fixed on the other side of the chain transmission mounting plate 137 through a dispensing pen mounting plate 1303. The above structural design of the annular track conveyor line 13 breaks the single function that the conventional conveyor line can only convey the fan frame. It also cooperates with the gasket conveying and assembling mechanism 15 to correct the conveyed gasket, cooperates with the snap ring conveying and assembling mechanism 16 to apply oil to the conveyed snap ring to increase the adhesion between the snap ring and the middle tube and fix the fan frame to cooperate with the hot melt mechanism 20 to perform hot melt processing on the middle tube of the fan frame, and its function is more diversified.

One end of the limit card board 1314 away from the fixture moving seat 1311 is recessed inward to form a limit groove 1315. The fan frame fixture 1310 is installed on the top of the fixture moving seat 1311 and is used for carrying the fan frame.

[0101] By adopting the above technical solution, the jig moving seat 1311 slides cyclically on the annular track 136 through the upper guide wheel 1312 and the lower guide wheel 1313, and the fan frame jig 1310 moves with the jig moving seat 1311 to perform cyclic transmission of the fan frame jig 1310.

[0103] By adopting the above technical solution, the swing rod driving device 1325 drives the limiting rotating shaft connecting rod 1324 to swing around the limiting rotating shaft 1322, and the limiting rotating shaft 1322 drives the limiting swing rod 1321 to swing around it. When the swinging end of the limiting swing rod 1321 is clamped with the limiting groove 1315 of the limiting clamping plate 1314, the limiting swing rod 1321 limits the movement of the jig moving seat 1311 on the annular track 136, and finally realizes the movement limit of the fan frame jig assembly 131 on the annular track 136, which ensures that the fan frame jig assembly 131 can stably cooperate and work at the current working station. In this embodiment, the swing rod driving device 1325 is set as a cylinder.

[0104] Referring Figure 22 As shown, the gasket correction assembly 139 includes a correction clamp arm driving device mounting plate 1391, a correction clamp arm opening and closing driving device 1392 and two correction clamp arms 1393.

The peristaltic dispensing pen 130 of the annular track conveyor line 13 is installed in an inverted manner. Since a little oil will come out of the tip of the peristaltic dispensing pen 130, the snap ring conveying and assembling mechanism 16 conveys the snap ring to stick oil on the tip of the peristaltic dispensing pen 130 and then installs it on the fan frame, making it easier to install the snap ring into the middle tube and the snap ring with oil sticking has adhesion to the middle tube, preventing the snap ring from being lifted when the snap ring conveying and assembling mechanism 16 withdraws from the middle tube. The hot melt pressing frame assembly 1301 fixes the fan frame jig 1310 to cooperate with the hot melt mechanism 20 to perform hot melt processing on the middle tube of the fan frame. It automatically completes operations such as the cyclic conveyance of the fan frame jig 1310, gasket deviation correction, snap ring oiling, and fixing of the fan frame jig 1310, and has the advantages of high efficiency in assembling the gasket and the snap ring on the fan frame and good stability in assembling the gasket and the snap ring.
