Description

Technical Field

[0001] This invention relates to the field of coil wrapping machines, and more particularly to an integrated machine for automatic coil insertion, paper wrapping, and tape wrapping. Background Technology

[0002] For starter coils and stator coils, the process of inserting insulating paper into the center lead and wrapping the inner winding requires padding with insulating paper between the center lead and the inner winding before wrapping the coil with tape. This prevents short circuits between the coil lead and the winding. Most coil paper insertion and tape wrapping processes on the market are done manually. First, the operator manually pushes and pries open the center lead of the coil to separate it from the inner winding, then inserts pre-cut insulating paper between the center lead and the inner winding, pressing the insulating paper tightly between them to ensure a close fit. The insulating paper is then manually inserted into the coil. During the paper insertion process, manually pushing the coil's center pin may result in insufficient separation from the inner coil, making it difficult to insert the insulating paper. Forcing the insulating paper in may cause wrinkles or misalignment. Furthermore, manual positioning of the coil's insulating paper is inaccurate, and deviations in the insertion position can cause partial contact between the center pin and the coil, leading to a short circuit and ultimately affecting the quality of the finished coil. To address these shortcomings of traditional manual coil insulating paper insertion and the lack of an integrated machine on the market that can automatically complete multiple processes such as paper insertion and tape wrapping, developing an integrated machine that automatically positions the coil, inserts the paper, and wraps the tape has become the primary problem to be solved.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By installing a coil conveying mechanism and a coil positioning mechanism on the machine tool respectively, with the coil conveying mechanism located on one side of the coil positioning mechanism, and designing the structures of the coil conveying mechanism and the coil positioning mechanism respectively, the coil conveying mechanism can realize fully automatic conveying of coils between various workstations to cooperate in completing the corresponding processing technology, and has the advantage of high conveying efficiency; the coil positioning mechanism can realize the positioning of the coil before paper insertion, so as to automatically complete the pre-positioning and pre-paper insertion positioning of the coil, and has the advantages of high positioning efficiency and high positioning accuracy, ensuring the accuracy of subsequent coil paper insertion.

[0016] 2. This machine is equipped with a paper feeding mechanism and an insulating paper folding mechanism on the machine base, a paper insertion mechanism within the coil positioning mechanism, and a coil pin actuation mechanism on one side of the support frame. The paper feeding mechanism is located between the insulating paper folding mechanism and the paper insertion mechanism. Through the separate design of the structures of the paper feeding mechanism, insulating paper folding mechanism, coil pin actuation mechanism, and paper insertion mechanism, the paper feeding mechanism can accurately position and feed the insulating paper strip, ensuring high efficiency in inserting the insulating paper segment into the coil. The insulating paper folding mechanism simultaneously feeds the unwound insulating paper and folds the upper end of the insulating paper strip, achieving precise control of the fold width, resulting in smooth folds, high folding efficiency, and good folding effect. The coil pin actuation mechanism uses a fork to actuate... The coil's center pin separates from the inner winding. A paper insertion mechanism automatically and precisely inserts insulating paper into the coil, isolating the contact area between the center pin and the inner winding. This method offers advantages such as precise paper insertion positioning, high efficiency, and excellent insertion effect, ensuring high-quality finished coils. It avoids short circuits caused by partial contact between the center pin and the coil due to paper insertion deviations. This effectively solves the problems common in most commercially available coils where manual separation of the center pin and inner winding results in insufficient gaps, leading to difficulties in inserting insulating paper, wrinkled or misaligned paper, poor coil quality, low yield, low efficiency in inserting insulating paper and coating, high production costs, and low automation.

The coil wrapping tape shifting mechanism... The positioning mechanism, in conjunction with the tape wrapping mechanism, enables automatic tape wrapping of two long sides and one short side of coils of different sizes.

The traction component 62 provides power for the conveying of the insulating paper tape, and the first guide limiting component 61 and the second guide limiting component 63 limit and guide it, so that the insulating paper tape has the advantages of accurate conveying positioning and high conveying efficiency, ensuring high efficiency in inserting insulating paper segments into the coil.

[0072] Reference Figure 20 and Figure 21 As shown, the coil pin actuation mechanism 8 includes a second linear guide rail 81, a fork drive assembly 82, a fork mounting bracket 83, and a fork 84. The second linear guide rail 81 is horizontally mounted on one side of the support frame 7. The fork mounting bracket 83 is slidably mounted on the second linear guide rail 81. The fork 84 is mounted on the fork mounting bracket 83 and is used to actuate the middle pin of the coil 13 back and forth. The fork drive assembly 82 is mounted on the same side of the support frame 7 and is connected to the fork mounting bracket 83 in a transmission manner. The fork drive assembly 82 drives the fork mounting bracket 83 to reciprocate on the second linear guide rail 81.

[0073] Reference Figure 20 and Figure 21As shown, by adopting the above technical solution, the shift fork 84 engages the center pin 131 of the coil 13. The shift fork drive assembly 82 drives the shift fork mounting bracket 83 to reciprocate on the second linear guide rail 81. The shift fork mounting bracket 83 drives the shift fork 84 to reciprocate. The shift fork 84 moves the center pin 131 of the coil 13 to one side, separating the center pin 131 of the coil 13 from the inner winding. The paper insertion mechanism 9 inserts the cut insulating paper segment between the center pin 131 of the coil 13 and the inner winding. The shift fork 84 moves the center pin 131 of the coil 13 to the other side, causing the center pin 131 of the coil 13 to recover its deformed state. The insulating paper segment is pressed tightly onto the inner winding of coil 13, thus fixing the insulating paper segment together with the middle pin 131 of coil 13 and the inner winding. The middle pin 131 of coil 13 and the inner winding firmly fix the insulating paper segment. By moving the middle pin 131 of coil 13 with the fork 84, the middle pin 131 is separated from the inner winding, which facilitates the insertion of the insulating paper segment into coil 13 by the paper insertion mechanism 9. At the same time, it avoids the inability to insert the insulating paper segment into coil 13 due to the tight fit between the middle pin 131 and the inner winding, thus ensuring good insulation between the middle pin 131 and the inner winding of coil 13.

The two pressure plates 106 are respectively opposite to the insulating paper strips on both sides of the coil's center pin 131. The pressure head drive device 104 drives the pressure head 105 to move obliquely downward, thereby driving the two pressure plates 106 to move obliquely downward to press the insulating paper strips on both sides of the coil's center pin 131 onto the outer winding of the coil. The hot air gun 107 is mounted on the other end of the fixing clamp 102 and is used to blow hot air onto the insulating paper segments on the coil to shape them.

[0075] By adopting the above technical solution, after the paper insertion mechanism 9 inserts the insulating paper segment into the coil, the shaping drive device 101 drives the fixing clamp 102 to move towards the coil positioning mechanism 2. The fixing clamp 102 drives the drive device mounting rod 103 to move, thereby driving the pressure head drive device 104 and the pressure head 105 to move above the coil with the insulating paper strip inserted on the coil positioning mechanism 2. The pressure head drive device 104 drives the pressure head 105 to move diagonally downward, thereby driving the two pressure plates 106 on the pressure head 105 to press the folded edges of the insulating paper on both sides of the coil's center pin 131 onto the coil. On the outer layer of the coil, the insulating paper segment is pressed and shaped. Although the folded edge of the insulating paper tape is unfolded, the creases on the insulating paper tape are retained. The part of the insulating paper tape opposite to the outer layer of the coil does not curl up, so that the folded edge of the insulating paper tape can fit with the outer layer of the coil. The fixing clamp 102 drives the hot air gun 107 to move above the same coil. The hot air gun 107 blows hot air on the insulating paper segment on the coil to heat and shape it. The shaped insulating paper segment fits tightly with the surface of the coil, so that the insulating paper segment has the advantages of high shaping efficiency and good shaping effect.

The coil carrier 1157 can drive the coil to rotate while moving the coil in a horizontal two-dimensional plane. When the coil conveying mechanism 3 conveys the coil with the insulating paper tape inserted to the coil carrier... When the coil carrier 1157 is in place, the coil X-axis moving assembly 111 and the coil Y-axis moving assembly 113 jointly move the coil carrier 1157 to the tape wrapping mechanism 12. After the tape wrapping mechanism 12 completes the tape wrapping on one side of the coil, the carrier rotation drive device 1158 drives the coil carrier 1157 to rotate to rotate the coil 180 degrees.

After the tape wrapping mechanism 12 completes the tape wrapping on both sides of the coil, the coil X-axis moving assembly 111 and the coil Y-axis moving assembly 113 jointly transfer the coil carrier 1157 and the wrapped coil to the machine. On the side of platform 1, the coil conveying mechanism 3 picks up the coated coil from the coil carrier 1157 and conveys it to the next station; the coil carrier 1157 adjusts the position of the limiting block 11575 at the side limiting seat 11574 through the positioning hole 11576 and the screw, so as to limit the coil of different sizes, so as to adapt to the bearing and limiting of coils of different sizes, and has strong versatility; the tensioning wheel 11501 tensions the second synchronous belt 1150, ensuring the stability of the second driving synchronous wheel 1159 driving the second driven synchronous wheel 1156 to rotate through the second synchronous belt 1150;The carrier rotation drive device 1158 drives the partition plate 11503 to rotate. When the first proximity sensor 11502 detects the partition plate 11503, the carrier rotation drive device 1158 stops driving the second active synchronous wheel 1159 to rotate, causing the coil carrier 1157 to rotate to a predetermined position.

[0087] By adopting the above technical solution, the coil wrapping tape shifting mechanism 11 moves the coil to the wrapping tape mechanism 12 and moves one side of the coil into the gear ring 120403. At the same time as the coil moves into the gear ring 120403, it contacts and adheres to the tape segment inside the gear ring 120403. The wrapping drive device 1205 drives the drive gear 12045 to rotate through the wrapping transmission assembly 1206, which in turn drives the two driven gears 12047 to rotate. The two driven gears 12047 together drive the gear ring 120403 to rotate. The adhesive tape 120405 on the two second clearance holes 120404 of the gear ring 120403 rotates with the gear ring 120403 and applies the tape to one side of the coil to achieve automatic wrapping of the coil. When the second proximity sensor 12065 detects the notch on the sensing plate 12064, the coating drive device 1205 stops driving the coating assembly 1204 to coat the coil. The opening of the toothed ring 120403 is aligned with the gap between the two arc plates 12049, so that the toothed ring 120403 rotates to the initial positioning position, which facilitates the commutated coil or the next coil to move into the toothed ring 120403 to continue the next round of coating work.

The tape pulling drive device 1209 drives the fourth driving synchronous pulley to rotate, and the fourth driving synchronous pulley drives the fourth synchronous belt to run on the two fourth driven synchronous pulleys. The fourth synchronous belt drives the slide 12081 to slide up and down on the third linear guide rail 1207 through the connecting block 120911.

[0090] By adopting the above technical solution, the slide block 12081 drives the first tape clamping finger 12084 and the second tape clamping finger 12086 to pass through the first clearance hole 120401 and the second clearance hole 120404 of the coating assembly 1204 to reach the cutter frame 12022 of the cutting assembly 1202. The clamping finger driving device 12083 drives the second tape clamping finger 12086 to move toward the first tape clamping finger 12084. The second tape clamping finger 12086 and the first tape clamping finger 12084 close together to clamp the front end of the tape. The tape pulling driving device 1209 drives the tape pulling assembly 1208 to descend and leave the coating assembly 1204 through the tape pulling transmission assembly 12091 to pull out the tape of a predetermined length.The glue feeding wheel drive device 124 drives the glue feeding wheel 125 to rotate, thereby pulling the tape out from the tape reel 122. The gravity roller 128 uses its own gravity to tension and convey the tape. After being conveyed by the tape conveyor roller group 129, the tape passes sequentially through the pressing assembly 1201, the tape limiting assembly 120, and the tape cutting assembly 1202. The tape limiting assembly 120 limits and guides the tape conveying. The pressing assembly 1201 presses the tape and positions the front end of the tape on the tape limiting base plate 1202. The tape pulling drive device 1209 drives the tape pulling assembly 1208 to rise through the tape pulling transmission assembly 12091. The first tape gripper finger 1208... 4. The second tape gripper 12086 passes through the first clearance hole 120401 and the second clearance hole 120404 of the coating assembly 1204 respectively and reaches the tape cutting assembly 1202. The tape pulling assembly 1208 clamps the front end of the tape, the tape pressing assembly 1201 releases the tape, and the tape pulling drive device 1209 drives the tape pulling assembly 1208 to descend on the third linear guide rail 1207 to pull the tape through the tape pulling transmission assembly 12091. The tape passes through the first clearance hole 120401 and the second clearance hole 120404 of the coating assembly 1204. When the second photoelectric sensor 126 detects the slide 12081, the tape is pulled... The drive device 1209 stops driving the tape pulling assembly 1208 to pull the tape, achieving precise tape length pulling. The adhesive pressing assembly 1201 fixes the tape. The coil wrapping tape shifting mechanism 11 transmits the coil to the toothed ring 120403 of the wrapping assembly 1204. One side of the coil adheres to the tape inside the toothed ring 120403. The tape cutting assembly 1202 cuts the tape. The wrapping drive device 1205 drives the toothed ring 120403 of the wrapping assembly 1204 to rotate through the wrapping transmission assembly 1206 to wrap one side of the coil. When the wrapping reaches a predetermined number of turns on one side of the coil, the second proximity sensor 12065 senses the sensing plate 12. When the notch on 064 is reached, the coating drive device 1205 stops driving the coating assembly 1204 to coat the coil. At this time, the opening of the toothed ring 120403 is opposite to the gap between the two arc plates 12049, so that the toothed ring 120403 rotates to the initial positioning position, which facilitates the commutated coil or the next coil to move into the toothed ring 120403 to continue the next round of coating work. The coil coating tape shifting mechanism 11 moves or rotates the coil, so that the coating assembly 1204 can coat multiple places on the same side of the coil or coat the other side of the coil. It has the advantages of flexible coating operation, high coating efficiency and good coating effect.

[0091] This integrated automatic coil insertion and tape wrapping machine features a single-machine design that enables automatic coil transfer between various stations, automatic coil positioning before insertion, automatic separation of the coil's center lead from the inner winding, unwinding and conveying of the insulating paper roll, automatic folding of the top edge of the unwound insulating paper tape, automatic insertion of insulating paper segments between the coil's center lead and the inner winding, pressing and shaping of the inserted insulating paper segments, and automatic tape wrapping of the coil. This solves the problem of the lack of integrated machines on the market that can automatically complete these multiple processes for coils. Its automation, by separating the coil's center lead from the inner winding for precise insertion of insulating paper segments, ensures accurate insertion of the coil's center lead and inner winding. The insulation paper segment is precise and efficient, ensuring good insulation between the coil's center pin and the inner winding. This gives the coil advantages such as high efficiency, high precision, and good effect of inserting insulation paper segments, high efficiency and effect of wrapping, high yield of finished products, and high degree of automation. It also greatly reduces the labor intensity of workers and reduces production costs. In turn, it effectively solves the problems of poor quality, low yield, low efficiency of inserting insulation paper, low efficiency of wrapping, high production costs, and low degree of automation of most coils on the market that rely on manual separation of the coil's center pin and inner winding. Due to insufficient separation between the two, it is often difficult to insert the insulation paper, and the forced insertion of insulation paper results in wrinkles or misalignment.

All technical solutions that are the same as or equivalent to the contents described in the claims of the present invention should be included within the protection scope of the present invention.
