Description

Technical Field

[0001] This invention relates to the technical field of electronic component manufacturing, and more particularly to an automatic foot wrapping machine. Background Technology

[0002] In the production of electronic products such as filters and transformers, a magnetic ring (also known as a coil) needs to be placed inside the housing. The copper wire on the magnetic ring is wound onto pins on both sides of the housing for subsequent processing. In conventional production, the housing with the magnetic ring is placed into a winding fixture, which is then moved into a pin winding mechanism to wind the copper wire. The fixture is then output. However, during this process, it is impossible to trim excessively long copper wires on the magnetic ring. The transfer efficiency of the winding fixture is low. The next winding fixture can only be received after the previous one has been completed. Furthermore, without inspection capabilities, the winding quality can only be checked after the entire fixture has been discharged. Additionally, when different sizes of pins are needed on the same winding fixture during the winding process, timely replacement is not possible, resulting in low production efficiency.

Detailed Implementation

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1As shown in this embodiment, an automatic foot winding machine includes a feeding and cutting mechanism 1, a shifting and unloading mechanism 2, a transfer vision inspection mechanism 3, and a needle winding mechanism 4. The feeding and cutting mechanism 1 positions the foot winding fixture 119 and cuts the copper wire short. The shifting and unloading mechanism 2 places the foot winding fixture 119 with the cut copper wire into the transfer vision inspection mechanism 3 and discharges the foot winding fixture 119 after it has been wound. The transfer vision inspection mechanism 3 performs positioning detection on the input foot winding fixture 119 and performs visual inspection on the output foot winding fixture 119. The needle winding mechanism 4 winds the thick and thin copper wires on the foot winding fixture 119 onto a needle post.

[0036] The magnetic ring has been placed inside the plastic shell, which is fixed in the foot-winding fixture 119. After the foot-winding fixture 119 is positioned in the feeding and cutting mechanism 1, the excessively long copper wire is cut. The shifting and unloading mechanism 2 transfers the cut copper wire foot-winding fixture 119 to the transfer vision inspection mechanism 3 for visual inspection of the copper wire, magnetic ring, and plastic shell. If it meets the requirements, it is transferred to the bottom of the needle winding mechanism 4. The coarse and fine needles on the needle winding mechanism 4 use different sizes of needles to wind the copper wire according to the current thickness of the copper wire. Then, it returns to the visual position in the transfer vision inspection mechanism 3 to inspect the finished product status of each needle post. Finally, according to the inspection results of good and defective products, it is placed in different positions by the shifting and unloading mechanism 2 and discharged.

[0037] The specific structures of each institution are as follows:

[0038] like Figures 2 to 4 As shown, the feeding and cutting mechanism 1 includes an infeed conveyor belt 101 and a cutting bracket 102. Infeed side plates 103 are installed on both sides of the infeed conveyor belt 101. An infeed belt 104 is installed on the inner side of the infeed side plates 103. A foot-wrapping fixture 119 is placed on the infeed belt 104. An infeed stop cylinder 105 and an infeed positioning cylinder 106 are fixed on the infeed side plates 103. The drive ends of the infeed stop cylinder 105 and the infeed positioning cylinder 106 both extend to the infeed belt 104. A cutting vertical movement module 107 is installed on the cutting bracket 102. A cutting pneumatic finger 108 is connected to the drive end of the cutting vertical movement module 107. A cutting pneumatic finger 108 is connected to the drive ends of the cutting pneumatic finger 108 on both sides. A cutting blade 110 is fixed to the outer side of the cutting blade 109.

[0039] A magnetic ring is placed inside the plastic shell. The foot-winding fixture 119 with the plastic shell is placed between the two feed side plates 103 of the feed conveyor belt 101. The feed belt 104 drives the foot-winding fixture 119 to move. After the feed stop cylinder 105 extends its drive end to the feed belt 104, the position of the foot-winding fixture 119 is restricted. At the same time, the feed positioning cylinder 106 extends to fix the position of the foot-winding fixture 119. The foot-winding fixture 119 that continues to be conveyed is restricted by one feed stop cylinder 105 and one feed positioning cylinder 106 to continue conveying. In addition, one feed stop cylinder 105 and one feed positioning cylinder 106 are fixed and waiting for wire cutting. Then, the wire cutting vertical movement module 107 controls the wire cutting pneumatic finger 108 to move downward. The cutting head 109 presses on the plastic shell, and the wire cutting blades 110 on both sides are responsible for cutting the longer copper wires.

[0040] Feed drive wheel 111 and feed driven wheel 112 are respectively provided on both sides of the feed side plate 103. Feed belt 104 drives between the feed drive wheel 111 and the feed driven wheel 112. Feed motor 113 is fixed at one end of the feed side plate 103. Feed motor 113 is connected to feed drive wheel 111. In the structure that drives the foot jig 119 to move, feed motor 113 provides power, so that feed drive wheel 111 rotates. Feed driven wheel 112 rotates under the drive of feed belt 104. Feed belt 104 can drive foot jig 119 to move.

[0041] Specifically, the drive end of the feed stop cylinder 105 blocks the front side of the foot wrapping fixture 119, and the drive end of the feed positioning cylinder 106 presses against the side of the foot wrapping fixture 119. Moreover, a positioning notch 114 is provided on one side of the foot wrapping fixture 119. The drive end of the feed positioning cylinder 106 is inserted into the positioning notch 114. At the rear end of the feed conveyor belt 101, the feed stop cylinder 105 restricts the position of the cut foot wrapping fixture 119. The feed positioning cylinder 106 extends its drive end. If it senses that it has been inserted into the positioning notch 114, the current position of the foot wrapping fixture 119 is correct, and it continues to move backward. If it senses that it has not been inserted into the positioning notch 114, the direction of the foot wrapping fixture 119 is wrong, and the foot wrapping fixture 119 needs to be rotated 180 degrees in the horizontal direction to straighten the foot wrapping fixture 119 before moving it.

[0042] The drive end of the tangent vertical movement module 107 is fixed with a tangent pressure block 115. The tangent pneumatic finger 108 is located below the tangent pressure block 115. The tangent blade 110 is installed at an angle along the vertical direction. Moreover, a tangent cover 116 is fixed on the outside of the tangent pneumatic finger 108. The tangent cover 116 covers the foot wrapping fixture 119. The tangent vertical movement module 107 controls the tangent pressure block 115 to move downward, driving the tangent pneumatic finger 108 to press and fix the rubber shell on the foot wrapping fixture 119. At this time, the tangent cover 116 covers the current foot wrapping fixture 119 to prevent the cut copper wire from falling out. The inclined tangent blade 110 cuts downward inward, ensuring the accuracy of the tangent position and the quality of the copper wire break.

[0043] The wire cutter 102 has a waste wire outlet 117 in the middle and a waste wire guide tube 118 connected to the lower end of the waste wire outlet 117. The cut copper wire falls from the waste wire outlet 117 and is collected after passing through the waste wire guide tube 118.

[0044] like Figures 5 to 6 As shown, the shifting and unloading mechanism 2 includes a shifting component 201 and a discharge conveyor belt 202. The shifting component 201 is provided with a shifting bracket 203. A shifting transverse module 204 is horizontally installed on the shifting bracket 203. A good product pneumatic gripper 205, a defective product pneumatic gripper 206, and an infeed rotary cylinder 207 are connected to the drive end of the shifting transverse module 204. An infeed pneumatic gripper 208 is connected to the drive end of the infeed rotary cylinder 207. Discharge side plates 209 are installed on both sides of the discharge conveyor belt 202. A belt beam 210, a first discharge belt 211, and a second discharge belt 212 are installed on the inner side of the discharge side plate 209. A discharge motor 213 is installed on the outer side of the discharge conveyor belt 202. The discharge motor 213 synchronously drives the movement of the first discharge belt 211 and the second discharge belt 212.

[0045] The shifting and traversing module 204 controls the feeding pneumatic gripper 208 to move to the end of the feeding structure. Based on the correctness of the placement of the foot-wrapping fixture 119, the foot-wrapping fixture 119 in the reverse position is aligned by the feeding rotary cylinder 207 and then moved into the transfer structure. At the same time, the foot-wrapping fixture 119 that was originally wrapped in the transfer structure is grabbed by the good product pneumatic gripper 205 or the defective product pneumatic gripper 206 according to the detection status. If it is good, it is grabbed by the good product pneumatic gripper 205 and sent to the first discharge belt 211. If it is defective, it is grabbed by the defective product pneumatic gripper 206 and sent to the second discharge belt 212. The discharge motor 213 provides power to make the first discharge belt 211 and the second discharge belt 212 rotate, and together drive the foot-wrapping fixtures 119 of different masses to be discharged.

[0046] A horizontal shifting module 204 is connected to a vertical shifting module 214, and a horizontal shifting beam 215 is connected to the drive end of the vertical shifting module 214. The good product pneumatic gripper 205 and the defective product pneumatic gripper 206 are fixed on one side of the horizontal shifting beam 215, and the feeding rotary cylinder 207 is fixed on the other side of the horizontal shifting beam 215. The horizontal shifting module 204 controls the horizontal movement of the pneumatic gripper, and the vertical shifting module 214 controls the vertical movement of the pneumatic gripper. Driven by the horizontal shifting beam 215, the good product pneumatic gripper 205, the defective product pneumatic gripper 206, and the feeding pneumatic gripper 208 move up, down, left, and right synchronously, which makes it easier for the foot jig 119 to grasp and place the product.

[0047] Specifically, the discharge motor 213 is fixed at the lower end of the shifting bracket 203; the two ends of the discharge side plate 209 are respectively rotatably connected to the first discharge shaft 216 and the second discharge shaft 217, the first discharge shaft 216 is rotatably connected to the first discharge drive wheel 218 and the second discharge drive wheel 219, the second discharge shaft 217 is rotatably connected to the first discharge driven wheel 220 and the second discharge driven wheel 221, the first discharge belt 211 drives between the first discharge drive wheel 218 and the first discharge driven wheel 220, the second discharge belt 212 drives between the second discharge drive wheel 219 and the second discharge driven wheel 221, the drive end of the discharge motor 213 is connected to the first discharge shaft 216; the discharge sensor 222 is fixed on the outer side of the discharge side plate 209.

[0048] After a foot is detected as good, the foot-wrapping fixture 119 is gripped by the good pneumatic gripper 205 and placed onto the first discharge belt 211. After a foot is detected as defective, the foot-wrapping fixture 119 is gripped by the defective pneumatic gripper 206 and placed onto the second discharge belt 212. The discharge motor 213 provides power, and under the action of the first discharge shaft 216, the first discharge drive wheel 218 and the second discharge drive wheel 219 rotate together, synchronously driving the first discharge driven wheel 220 and the second discharge driven wheel 221 to rotate, so that the conveying of the first discharge belt 211 and the second discharge belt 212 is synchronized. After the discharge sensor 222 senses the presence of the foot-wrapping fixture 119, the discharge motor 213 starts the conveying power.

[0049] like Figures 7 to 8As shown, the transfer vision inspection mechanism 3 includes a vision component and a transfer module 301. The vision component is provided with a column 302, and a feed camera 303 and a discharge camera 304 are installed on the column 302. A slide plate 305 is installed on the drive end of the transfer module 301. An X-axis positioning cylinder 306 and a fixture fixing plate 307 are fixed on both sides of the slide plate 305, respectively. A Y-axis positioning cylinder 308 is fixed on the outer side of the fixture fixing plate 307. A fixture placement cavity is provided in the middle of the fixture fixing plate 307. An X-axis positioning stage 309 is integrally formed on the side of the fixture placement cavity away from the X-axis positioning cylinder 306, and a Y-axis positioning stage 310 is integrally formed on the side of the fixture placement cavity away from the Y-axis positioning cylinder 308.

[0050] After the copper wire is cut from the front end, the foot-winding fixture 119 is placed in the fixture placement cavity. The X-axis positioning cylinder 306 and the Y-axis positioning cylinder 308 jointly push the two sides of the foot-winding fixture 119, so that the foot-winding fixture 119 is positioned on the X-axis positioning table 309 and the Y-axis positioning table 310. Before the foot-winding fixture 119 is driven by the slide plate 305 to wind the feet, the feed camera 303 takes pictures to detect whether the foot-winding fixture 119 exists to prevent empty running. After the foot-winding is completed, the discharge camera 304 takes pictures of the needle column part of the foot-winding one by one to determine the quality of the foot-winding.

[0051] The lower end of the column 302 is equipped with a first light source 311 and a second light source 312. The feed camera 303 is located above the first light source 311, and the discharge camera 304 is located above the second light source 312. The first light source 311 provides light for the feed camera 303, while the second light source 312 provides light for the discharge camera 304.

[0052] A camera horizontal movement module 313 is provided on one side of the column 302. A moving motherboard 314 is connected to the drive end of the camera horizontal movement module 313. The second light source 312 and the discharge camera 304 are both fixed on the moving motherboard 314. The camera horizontal movement module 313 controls the discharge camera 304 to move horizontally. Then, driven by the transfer module 301, the position of each pin on the foot-wrapping fixture 119 can be photographed to determine whether the product is good after the foot is wrapped.

[0053] Specifically, both the drive end of the X-axis positioning cylinder 306 and the drive end of the Y-axis positioning cylinder 308 are connected to a positioning push plate 315, which pushes the foot-wrap fixture 119 to position it.

[0054] The fixture fixing plate 307 is provided with locking holes 316 around its perimeter. The screws in the locking holes 316 are threaded onto the slide plate 305. The fixture fixing plate 307 and the slide plate 305 are connected together through the locking holes 316, so that when the transfer module 301 moves through the slide plate 305, it can drive the foot-wrapping fixture 119 located in the fixture fixing plate 307.

[0055] Both ends of the transfer module 301 are equipped with transfer sensors 317, and a transfer sensor 318 is fixed on one side of the slide plate 305. The transfer sensor 317 and the transfer sensor 318 are connected by signal sensing. During the transfer process, the transfer sensor 317 senses the transfer sensor 318 to confirm the position, which facilitates accurate foot wrapping.

[0056] like Figures 9 to 13 As shown, the needle winding mechanism 4 includes a foot-winding vertical movement module 401, an upper foot-winding plate 402, and a lower foot-winding plate 403. A foot-winding mounting frame 404 is connected to the drive end of the foot-winding vertical movement module 401. An upper drive assembly 405 is connected to the upper end of the foot-winding mounting frame 404. The upper foot-winding plate 402 is mounted on the upper drive assembly 405. A lower drive assembly 406 is connected to the lower end of the foot-winding mounting frame 404. The lower foot-winding plate 403 is mounted on the lower drive assembly 406. An upper foot-winding motor 407 is fixed on the upper foot-winding plate 402. An upper needle 408 is rotatably connected to the upper foot-winding plate 402. The upper foot-winding motor 407 drives the rotation of the upper needle 408. A lower foot-winding motor 409 is fixed on the lower foot-winding plate 403. A lower needle 410 is rotatably connected to the lower foot-winding plate 403. The lower foot-winding motor 409 drives the rotation of the lower needle 410.

[0057] The transfer structure moves the foot-wrapping fixture 119 to below the foot-wrapping mounting frame 404. The foot-wrapping vertical movement module 401 drives the foot-wrapping mounting frame 404 to move downward. At the same time, based on the measurement of the position of each pin on the foot-wrapping fixture 119, the upper drive component 405 controls the upper foot-wrapping plate 402 to adjust in the horizontal direction so that the upper foot-wrapping needle 408 is aligned with the needle post. In addition, the lower drive component 406 also controls the lower foot-wrapping plate 403 to adjust in the horizontal direction so that the lower foot-wrapping needle 410 is aligned with the needle post. According to the winding sequence of the thick copper wire and the thin copper wire on the same needle post, the winding sequence of the upper foot-wrapping needle 408 and the lower foot-wrapping needle 410 is automatically controlled.
