Description

Technical Field

[0001] This utility model relates to the technical field of workpiece wrapping and processing equipment, and in particular to a fully automatic device for wrapping Nomi paper with adhesive. Background Technology

[0002] In the production and processing of products such as motor coils, electronic components, and wires and tubes, the coating of Nomex paper is a key process for achieving insulation, protection, and preventing loosening. The industry's requirements for the processing efficiency, precision, and consistency of this process are constantly increasing. Traditional manual Nomex paper coating operations rely on skilled workers, resulting in low efficiency, high labor costs, and defects such as uneven coating, loose Nomex paper, and cutting deviations, leading to a high product defect rate. Existing semi-automatic equipment requires manual assistance for operations such as feeding, positioning, and cutting the adhesive paper, resulting in disjointed processes, time-consuming changeover and debugging, and difficulty in adapting to the mass production needs of multi-specification products. Early fully automatic Nomex paper coating mechanisms were mostly single-function designs with narrow adaptability. They generally suffered from poor control of the Nomex paper force, easy wrinkling and breakage, and lack of precise positioning modules and insufficient processing accuracy, failing to meet the current industry development requirements of precision manufacturing and high-efficiency production.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figures 1 to 7 As shown, a fully automatic Nomex paper wrapping device is composed of a base plate 1, a variable pitch feeding unit 2, a tape feeding unit 4, a Nomex paper cutting unit 5, and a wrapping and pressing unit 3. These functional units together form an integrated fully automatic wrapping processing equipment. The base plate 1 serves as the overall supporting structure. The base plate 22 of the variable pitch feeding unit 2 is fixedly installed in the middle of the base plate 1, responsible for automatic workpiece feeding, pitch adjustment, and rotary wrapping. Symmetrical mounting holes on the base plate 1 are used to assemble the tape feeding unit 4. The wrapping and pressing unit 3 is adjacent to the mounting holes and fixedly connected to the tape feeding unit 4 at its bottom, ensuring a continuous and stable supply of tape material. The wrapping and pressing unit 3 serves as the core processing station, integrating tape clamping, tension adjustment, cutting, and wrapping functions. The Nomex paper cutting unit 5 is mounted on top of the wrapping and pressing unit 3, realizing automatic Nomex paper feeding, pressing, and fixed-length cutting. All units work together to complete the fully automatic Nomex paper wrapping process.

[0021] The tape feeding unit 4 includes a rubber-coated wheel mounting component 41 and a rotating support shaft 42. One end of the rubber-coated wheel mounting component 41 is fixed to the bottom side wall of the wrapping and pressing unit 3 through a mounting hole, and the other end extends downward in a suspended manner. The rotating support shaft 42 is horizontally fixed to the suspended end of the rubber-coated wheel mounting component 41. The outer side of the rotating support shaft 42 is sequentially fitted with a tape spacer 43, a tape seat 44, and a retaining ring along the axial direction. The retaining ring is used to fix the tape seat 44 at the end of the rotating shaft and plays a limiting role. A photoelectric recognition piece is fixed to the side of the tape spacer 43 near the rubber-coated wheel mounting component 41. A first photoelectric sensor 45 is fixed to the rubber-coated wheel mounting component 41. The photoelectric recognition piece and the first photoelectric sensor 45 form a detection mating structure for measuring the feeding length of the tape and providing data support for the use of the cutter 335. The tape holder 44 has several through-type limiting grooves and matching mounting grooves on its side along the axial direction. A tape holder movable strip 47 is set in the limiting groove. One end of the tape holder movable strip 47 is hinged to the tape holder 44 by a pin, and the other end extends out of the tape holder 44 end face for a predetermined length. A miniature compression spring 46 is fixed to the middle of the tape holder movable strip 47. One end of the miniature compression spring 46 is fixed to the bottom of the mounting groove, and the other end extends out of the tape holder 44 side for a specified length. The miniature compression spring 46 enables the tape holder 44 to adapt to different tape rolls and fixes the tape rolls to ensure the stability of the feeding.

[0022] During the operation of the tape pressing unit 3, the guide shaft cylinder drives the push plate 321 and the tension-relieving guide shaft 322 to slide laterally. This, in conjunction with the upper and lower arranged second limiting shaft 325, first limiting shaft 323, and guide shaft 324, completes the adjustment and guiding of the tape tension, preventing the tape from becoming loose or deformed during transport. A photoelectric recognition piece is fitted around the outer periphery of the guide shaft 324 near the vertical support 31. The photoelectric recognition piece and the fourth photoelectric sensor 326 fixed at the corresponding position form a detection cooperation, which works in conjunction with the first photoelectric sensor 45 for detection. The length of the tape pulled out; the cutting component 33 includes a base 331 and an L-shaped rod 332. The L-shaped rod 332 is integrally formed from mutually perpendicular long rod segments and short rod segments. The long rod segment is fixedly assembled to the vertical support base 31, and the short rod segment extends outward from the end of the long rod segment to form a suspended free end. The base 331 is fixedly connected to the side wall of the vertical support base 31. The base mounting cylinder, the cutter mounting cylinder 333, and the glue pressing plate mounting cylinder 334 are respectively fixed to different side walls of the base 331. These three sets of independent cylinders on the base 331 respectively drive the glue-coating roller 337. The cutting blade 335 and the pressure plate 336 slide along their corresponding guide axes, automating the switching between workpiece coating, material cutting, and tape clamping processes. The short section of the L-shaped rod 332 vertically limits the pressure plate 336, preventing it from overtraveling. This clamps the tape before the cutting blade 335 cuts, allowing the tape end to be pulled out by the grippers during the next use. The clamping assembly 34, through the piston rod of the pen-shaped cylinder 341 and the sliding device, drives the L-shaped tape-pulling adapter plate 342 to move laterally, moving the long section of the L-shaped tape-pulling adapter plate 342 away from the short section. A tape-pulling mounting plate 343 is fixed to the inner side of one end. A clamping mounting cylinder 344 is fixed to the top of the tape-pulling mounting plate 343. The telescopic output end of the clamping mounting cylinder 344 faces the variable pitch feeding unit 2 and is respectively connected to the upper jaw 345 and the lower jaw 346. The upper jaw 345, the lower jaw 346, the cutter 335, and the pressure plate 336 are on the same working plane. The clamping mounting cylinder 344 drives the upper and lower jaws to open and close to clamp the tape, accurately completing the tape pulling and positioning operations. The clamping, cutting, and pressure stations are set on the same plane to ensure uniform processing accuracy.

[0023] The Nomi paper feeding and cutting unit 5 uses the pressure-bonding mounting base 51 as a support base. The Nomi paper roll is assembled on the material tray 541. The material tray motor 542 is fixedly installed on the side of the vertical support plate 544 near the variable pitch feeding unit 2. The bottom of the vertical support plate 544 is fixed to the upper surface of the base plate 1. The material tray motor 542 drives the central rotating shaft to rotate the material tray 541, realizing automatic feeding of Nomi paper. The Nomi paper is guided and conveyed by the linear guide shaft 545. The third photoelectric sensor 543 is fixedly installed on the extension plate and located at the Nomi paper feed unit 541. On the side of the linear guide shaft 545 at the end of the paper feeding direction, the third photoelectric sensor 543 detects the paper feeding status in real time and provides signal feedback for the cutting process; the upright plate 521 of the pressure bonding assembly 52 is fixedly connected to one side of the upper surface of the pressure bonding mounting base 51, and the top of the upright plate 521 away from the variable pitch feeding unit 2 is fixed with a vertical slide rail 525. The vertical slide rail 525 is matched with a slider and the side away from the upright plate 521 is fixed with a pressure bonding tape 523. When the pressure bonding tape 523 moves down, it is limited together with the limit block. In coordination, the first cylinder 524, fixed to the top of the upright plate 521 via the first cylinder mounting plate, drives the telescopic movable part 527 to move downward, thereby pressing the first compression spring 526. The flexible pressing force of the spring is transmitted to the bottom Nomi paper and tape through the tape pressing part 523, thereby achieving the effect of pressing the material. The flexible pressing force provided by the first compression spring 526 can prevent rigid extrusion from damaging the Nomi paper. The limit block limits the downward movement of the tape pressing part 523 to prevent over-travel pressing. The Nomi paper is conveyed to the glue-coating roller. At the location of mounting base 531, the active roller motor 534 drives the active roller 535 to rotate, which, together with the driven roller 536, clamps and conveys the Nomi paper. By rotating the top screw 538 on the top of the glue roller mounting base 531, the rectangular spring 537 elastically pushes the driven roller connector, thereby making the driven roller 536 adaptively fit the thickness of the Nomi paper and ensure the conveying fit. The cutting cylinder drives the movable blade 533 to swing around the pin shaft and engage with the fixed blade 532 to complete the fixed-length cutting of the Nomi paper.

[0024] When the variable-pitch feeding unit 2 transports workpieces, the lead screw motor drives the lead screw 25 to rotate, causing the moving platform 24 to slide laterally along the first sliding rail 26, thereby causing the entire feeding section to slide laterally, realizing the lateral position adjustment of the workpiece; the vertical thin cylinder 27, in conjunction with the linear bearing 28, drives the feeding plate 23 to rise and fall vertically, completing the workpiece feeding and lifting action; the piston rod of the longitudinal movement cylinder 29 drives the fixed seat 211 to move longitudinally, thereby driving the rotating component 21 to slide longitudinally along the longitudinal slide rail, realizing the variable-pitch adjustment of the spacing of multiple sets of workpieces, adapting to different... To meet the same processing spacing requirements, the rotary motor 213 of the rotating assembly 21 outputs power to drive the drive wheel to rotate, thereby driving the driven wheel 214, which is connected by the synchronous belt 219, to rotate. This, in turn, drives the rotating shaft through the bearing seat 212 to rotate, and finally drives the turntable base plate 215 to rotate, thus achieving the workpiece angle rotation for wrapping with Nomi paper. The finger cylinder 216 drives the two side grippers 217 to clamp and fix the workpiece. The second photoelectric sensor 218 works in conjunction with the photoelectric recognition sheet to detect the rotation position of the turntable, ensuring accurate workpiece rotation alignment without angular deviation.

[0025] Working principle: The tape feeding unit 4 first feeds the tape. After being adjusted by the guide shaft assembly 32, the tape enters the glue passage formed by the tape pressing component 523, the pressing base plate 522 and the limiting plate. Then, the end of the tape passes through the pressing plate 336 and the cutter 335 and is held by the upper and lower jaws. As the piston rod of the pen-shaped cylinder 341 extends, it drives the tape to the designated position to complete the preparation before the tape is coated.

[0026] After the variable pitch feeding unit 2 delivers the workpiece to the designated station, the workpiece adheres to the tape below and is tightly attached to the coating roller 337. At this time, the clamping and mounting cylinder 344 drives the upper and lower grippers to release the tape end, and the rotary motor 213 of the rotating assembly 21 outputs power. The rotation of the driving wheel drives the driven wheel 214 to rotate through the synchronous belt 219, which in turn drives the rotating shaft fixed to the driven wheel 214 to rotate. The rotation of the rotating shaft drives the turntable base plate 215 and the workpiece fixed on the turntable base plate 215 to rotate, thereby realizing the first coating process.

[0027] After wrapping the tape to the specified number of turns, the cutter 335 cuts the tape. The rotating assembly 21 continues to rotate until all excess tape is wrapped around the workpiece, then stops. Under the lifting action of the thin cylinder 27, the workpiece leaves the wrapping roller 337. The upper and lower grippers, driven by the pen-shaped cylinder 341, grip the tape end at the cutter 335 and continue pulling it to the specified feeding position. Once in position, the workpiece falls to the wrapping position, tightly adhering to the wrapping roller 337. The Nomi paper feeding assembly 54 feeds Nomi paper, which passes through the linear guide shaft 545 and the third photoelectric sensor 543. The Nomi paper is fed by a combination of the active roller 535 and the driven roller 536. The tape and Nomi paper are pressed together at the pressing base plate 522. At this time, the rotating component 21 continues to rotate to perform a second wrapping of Nomi paper. The third photoelectric sensor 543 identifies the feeding length of Nomi paper. After reaching the specified length, it transmits a signal to the cutting component 53. The piston rod of the cutting cylinder retracts, driving the movable blade 533 to swing around the pin shaft and engage with the fixed blade 532 to complete the fixed-length cutting of Nomi paper. The rotating component 21 continues to rotate to wrap the tape. After the tape is wrapped a specified number of times, the cutting blade 335 cuts the tape. The rotating component 21 continues to rotate until all the excess tape is wrapped on the workpiece and then stops, thus completing the fully automatic wrapping of Nomi paper on the workpiece.
