Description

Technical Field

[0001] This invention relates to the field of carrier tape processing technology, and more specifically, to a carrier tape processing apparatus and process method with automatic reel changing capability. Background Technology

[0002] Carrier tape is a packaging material used in automated production lines. It is typically used to package and transport small electronic components, semiconductor devices, connectors, resistors, capacitors, and other precision parts. The main function of carrier tape is to arrange and fix these small parts in an orderly manner on the tape material so that automated equipment can pick them up, assemble them, and test them.

[0003] Currently, carrier tape processing equipment on the market typically feeds an initial carrier tape made of polystyrene into the processing line, heats it with a heating device, and then enters a forming device. The heated carrier tape is stamped and formed by an upper and lower die. Next, the stamped carrier tape is punched, and finally, the processed carrier tape is wound up by a winding wheel, thus realizing the processing of the carrier tape.

[0004] However, current carrier tape changing devices on the market usually require manual removal of the old reel and placement of the new reel for winding. This necessitates pausing the entire production line for the reel change, resulting in low efficiency and hindering the continuity of machine operation.

[0005] Finally, during the winding process of the carrier tape, there are generally two modes: winding a single carrier tape individually and winding multiple carrier tapes simultaneously. If the winding mode is switched, different winding reels need to be changed, which will cause the problem of needing to change different winding reels every time the production mode is changed. In addition, if a single carrier tape is wound directly during the production process, it will cause the single carrier tape to be wound together, resulting in the problem of concentrated heat. During the winding of a single carrier tape, adhesion may occur. If multiple carrier tapes are wound simultaneously, heat will be transferred between the carrier tapes, causing the carrier tapes to deform and adhere to each other. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic reel-changing carrier tape processing device and its process method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0018] By adopting the above technical solution, an edge-adhesive extension rod is slidably installed at one end of the edge-adhesive connecting rod. The edge-adhesive connecting rod can slide as far as needed. When the edge-adhesive extension rod extends to the winding part of the winding unit, the edge-adhesive knife is in contact with the winding position of the winding unit. Only the tape needs to be pasted on the top of the carrier tape to directly allow the carrier tape to be in contact with the winding part of the winding unit for direct winding. This achieves the effect of allowing the carrier tape to be in contact with the winding part of the winding unit for direct winding.

[0019] The present invention is further configured such that: the cutting module includes two cutting mounting plates, the two cutting mounting plates are respectively mounted on the cutting groove, and a cutting cylinder is symmetrically mounted in the middle of the two cutting mounting plates.

[0025] A process method for an automatically changeable carrier tape processing device, comprising the following steps:

[0026] S1. The unwinding motor drives the unwinding reel to rotate and feed the initial material of the carrier belt. The carrier belt is processed by the heating mechanism and the forming mechanism. The feeding mechanism transports the processed carrier belt to the sprocket drive unit.

[0027] S2. If a single carrier belt is being processed, the sprocket drive unit supports and conveys the processed single carrier belt, the material distribution mechanism continues to convey the carrier belt, and the material application unit adjusts the feeding angle and cools the carrier belt.

[0028] S3. If multiple carrier belts are being processed, the sprocket drive unit supports and conveys the processed multiple carrier belts. The multiple carrier belts are divided by the material distribution mechanism. After the multiple carrier belts are divided, the feeding angle is adjusted by the material application unit and the carrier belts are cooled.

[0029] S4. If a single carrier tape is being processed, the feeding angle is adjusted by the bonding unit, and the winding unit is adjusted before winding.

During the winding process, the winding unit cools the carrier belt. If multiple carrier belts are being processed, the pressing unit rotates during the winding process to limit the wound portion. During the winding process, the winding unit cools the two sides of the multiple carrier belts, and the cooling unit cools the middle portion of the multiple carrier belts.

[0031] S6. After winding is completed, the material attaching unit cuts the carrier tape and resets, the material pressing unit resets, and the turntable drive drives the turntable to rotate to switch the winding unit.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting up a winding unit to complete winding, the turntable driver can drive the turntable to rotate. After the turntable rotates, the unwound winding unit is replaced for winding, thus achieving the effect of automatic turntable changing after the winding unit has finished winding.

[0034] 2. An edge-adhesive extension rod is slidably installed at one end of the edge-adhesive connecting rod. The edge-adhesive connecting rod can slide to the required extension distance. When the edge-adhesive extension rod extends to the winding part of the winding unit, the edge-adhesive blade is in contact with the winding position of the winding unit. Only the tape needs to be pasted on the top of the carrier tape to directly allow the carrier tape to be in contact with the winding part of the winding unit for direct winding. This achieves the effect of allowing the carrier tape to be in contact with the winding part of the winding unit for direct winding.

[0035] 3. By installing water-cooling pipes in the middle of both the upper and lower reels, the wound portion of the carrier tape can be cooled. By symmetrically installing winding cylinders in the middle of the lower reel, and installing winding connecting plates at the output ends of the winding cylinders, with one side of the winding connecting plates connected to the upper reel, the spacing between the upper and lower reels can be adjusted according to the required width of the carrier tape.

[0063] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0065] Please see Figure 1-20 The present invention provides the following technical solutions:

[0066] In Example 1, because current carrier tape changing devices on the market usually require manual removal of the old take-up reel and placement of the new take-up reel for winding, the entire production line needs to be paused for the reel change, resulting in low efficiency and hindering the continuity of machine operation.

[0067] See Figure 1 An automatic reel-changing carrier tape processing device includes a carrier tape forming unit 1, which is used to process the carrier tape into shape. A sprocket drive unit 2 is installed on the top of the carrier tape forming unit 1. The sprocket drive unit 2 is used to transport and support the carrier tape processed by the carrier tape forming unit 1. A material application unit 3 is provided at one end of the sprocket drive unit 2. The material application unit 3 is used to adjust the angle of the carrier tape transport and to perform air cooling on the carrier tape.

[0068] See Figures 1 to 6 The carrier tape forming unit 1 includes a carrier tape forming base 11. An unwinding reel 13 is mounted above the carrier tape forming base 11. An unwinding motor 12 is mounted on the side wall of the unwinding reel 13. The output end of the unwinding motor 12 is fixedly mounted to the unwinding reel 13. The unwinding reel 13 contains carrier tape material. The unwinding motor 12 drives the unwinding reel 13 to rotate and unwind the carrier tape material. A heating mechanism 14 is mounted on one side of the unwinding reel 13. The heating mechanism 14 heats the carrier tape, allowing the carrier tape material to enter the plastic temperature range. A forming mechanism 15 is mounted on the side of the heating mechanism 14 away from the unwinding reel 13. The forming mechanism 15 shapes the heated carrier tape material. A feeding mechanism 16 is provided on the side of mechanism 15 away from heating mechanism 14. The feeding mechanism 16 conveys the processed carrier belt forward. A separating mechanism 17 is provided on the side of feeding mechanism 16 away from forming mechanism 15. If multiple carrier belts are being processed, the separating mechanism 17 can separate the processed multiple carrier belts. A conveying mechanism 18 is provided on the side of separating mechanism 17 away from feeding mechanism 16. The conveying mechanism 18 can continue to convey the separated multiple carrier belts to bonding unit 3. If a single carrier belt is being processed, the separating mechanism 17 only plays the role of conveying and supporting, and does not separate the single carrier belt. The conveying mechanism 18 continues to convey the single carrier belt to bonding unit 3.

[0069] See Figures 1 to 6A disc changing unit 4 is provided on the side of the material application unit 3 away from the sprocket drive unit 2. The disc changing unit 4 includes a disc changing frame 41, which is located at one end of the carrier tape forming unit 1. A disc changing mounting plate 43 is installed on the disc changing frame 41. A turntable drive 46 is installed in the middle of the disc changing frame 41 and the disc changing mounting plate 43. A disc changing connecting plate 45 is installed below the turntable drive 46 and is connected to the disc changing frame 41. A turntable 42 is installed at the output end of the turntable drive 46, which can drive the turntable 42 to rotate. An arc-shaped groove 44 is provided below the disc changing mounting plate 43. A circular through hole is provided on the disc changing mounting plate 43, and the turntable 42 is rotatably installed in the circular through hole. Two winding units 5 are symmetrically installed on the sprocket drive unit 2. When one winding unit 5 finishes winding, the turntable drive 46 drives the turntable 42 to rotate. After the turntable 42 rotates 180 degrees, the unwound winding unit 5 is replaced for winding.

[0070] By setting up a winding unit 5 to complete winding, the turntable drive 46 can drive the turntable 42 to rotate. After the turntable 42 rotates 180 degrees, the unwound winding unit 5 is switched to wind up, thus achieving the effect of automatic turntable switching after the winding unit 5 has finished winding up.

[0071] The sprocket drive unit 2 includes a sprocket bracket 21, on which a sprocket rotating shaft 22 is rotatably connected. A sprocket mechanism 23 is rotatably mounted on the sprocket rotating shaft 22. The sprocket mechanism 23 can rotate on the sprocket rotating shaft 22 and can drive the carrier belt for transmission. Currently, sprocket drives on the market all adopt an integral structure. The sprocket mechanism 23 includes a sprocket body 231, which rotates on the sprocket rotating shaft 22. The sprocket body 231 is mounted on the sprocket rotating shaft 22. The body 231 is shaped like an H-beam. A first sprocket 232 is provided on a protrusion at one end of the sprocket body 231, and a second sprocket 233 is provided on a protrusion at the other end of the sprocket body 231. The cost is reduced by the split installation structure. The sprocket body 231 is a universal part. When the sprocket mechanism 23 needs to be replaced, only the first sprocket 232 or the second sprocket 233 needs to be replaced. After the carrier belt is processed and transmitted by the feeding mechanism 16, the sprocket mechanism 23 performs intermittent rotational motion, driving the carrier belt forward.

[0072] By setting the sprocket mechanism 23 as a split structure, the wear parts can be directly disassembled and replaced, reducing manufacturing costs.

[0073] The bonding unit 3 includes a bonding bracket 31, which is installed at one end of the carrier tape forming unit 1. A bonding drive module 32 is mounted on the bonding bracket 31. The bonding drive module 32 includes a bonding drive motor and a bonding drive shaft. The bonding drive motor is a stepper motor, which can precisely control the rotation angle. Four edge bonding mechanisms 33 are rotatably mounted on the bonding drive module 32. The bonding drive module 32 can drive the edge bonding mechanisms 33 to adjust their angles. The four edge bonding mechanisms 33 are mounted on the bonding drive shaft. Above the edge bonding mechanisms 33 is a... The system is equipped with a slide rail 34, on which three electric sliders 36 are slidably mounted. Each electric slider 36 has a material attaching sleeve 35 mounted below it. The material attaching sleeve 35 is connected to three edge attaching mechanisms 33. The three electric sliders 36 drive the material attaching sleeve 35 to move, and the material attaching sleeve 35 can drive the three edge attaching mechanisms 33 to move respectively. When a single carrier belt is being conveyed, only one edge attaching mechanism 33 is used for conveying. When multiple carrier belts are being conveyed, the positions of the edge attaching mechanisms 33 are moved to use multiple edge attaching mechanisms 33 for conveying.

[0074] The edge-applying mechanism 33 includes an edge-applying connecting rod 331, which is hollow. A sliding guide rail 3311 is installed on the inner wall of the edge-applying connecting rod 331. An electric edge-applying slider 3312 is installed on the sliding guide rail 3311. A rotating block 336 is installed below the edge-applying connecting rod 331 and is mounted on the material-applying drive shaft. The rotating block 336 is connected to the material-applying drive module 32. An edge-applying extension rod 332 is installed on the electric edge-applying slider 3312. The electric edge-applying slider 3312 can drive the edge-applying extension rod 332 to slide on the sliding guide rail 3311 according to the required extension distance. A cutting groove 3321 is provided above the edge-applying extension rod 332. Cooling fans 333 are symmetrically installed on the side wall of the edge-applying extension rod 332. When the carrier tape is conveyed in the edge-applying extension rod 332, the cooling fans 333 can cool the carrier tape. For heat dissipation, a cutting module 335 is installed on the edge-adhering extension rod 332, and an edge-adhering knife 334 is installed at one end of the edge-adhering extension rod 332. When the edge-adhering extension rod 332 extends to the winding part of the winding unit 5, the material-adhering drive module 32 drives the rotating block 336 to rotate to an angle that can fit with the winding unit 5. The edge-adhering electric slider 3312 can drive the edge-adhering extension rod 332 to extend, and simultaneously drive the edge-adhering knife 334 to fit with the winding position of the winding unit 5. In the prior art, tape is usually applied at the output of the carrier tape, and the tape is adhered to the winding unit 5 for winding. In this invention, after the tape is applied at the output end of the carrier tape, the edge-adhering knife 334 drives the tape to adhere to the winding unit 5. The winding unit 5 rotates to wind the carrier tape. By setting cooling fans 333 on both sides of the edge-adhering extension rod 332, the effect of heat dissipation of the carrier tape during the transport of the carrier tape is achieved.

[0075] See Figures 6 to 7An edge-adhesive extension rod 332 is slidably installed at one end of the edge-adhesive connecting rod 331. The edge-adhesive extension rod 332 can slide as far as needed. When the edge-adhesive extension rod 332 extends to the winding part of the winding unit 5, the edge-adhesive knife 334 is in contact with the winding position of the winding unit 5. Only the tape needs to be pasted on the top of the carrier tape to directly allow the carrier tape to be in contact with the winding part of the winding unit 5 for direct winding. This achieves the effect of allowing the carrier tape to be in contact with the winding part of the winding unit 5 for direct winding.

[0076] Two cutting mounting plates 3351 are respectively mounted on the cutting groove 3321. Cutting cylinders 3352 are symmetrically mounted in the middle of the two cutting mounting plates 3351. Cutting blades 3353 are arranged between the cutting cylinders 3352. The telescopic ends of the cutting cylinders 3352 can be connected to the top of the cutting blades 3353. When the required length is reached, the output end of the cutting cylinder 3352 extends, driving the cutting blades 3353 to move through the cutting groove 3321 towards the carrier belt, thus achieving the effect of directly cutting the carrier belt.

[0077] See Figures 8 to 13 A winding unit 5 is symmetrically installed in the middle of the reel changing unit 4. The winding unit 5 can change reels after the winding operation is completed and perform water cooling on the wound carrier tape. Both winding units 5 include a winding motor 54, which is installed on the side of the turntable 42 near the turntable drive 46. The output end of the winding motor 54 penetrates the turntable 42 and is installed on the lower reel 52. An upper reel 51 is fitted on the lower reel 52. The upper reel 51 and the lower reel 52 are of equal size. Water cooling pipes 511 are installed inside the upper reel 51 and the water cooling pipes 511 can cool the wound portion of the carrier tape. Winding cylinders 53 are symmetrically installed on the side wall of the lower reel 52 near the upper reel 51. A winding connecting plate 55 is installed on the output end of each winding cylinder 53. One end of the winding connecting plate 55 is connected to the upper reel 51. If a single carrier tape is being processed, the winding cylinder 53 retracts. The upper plate 51 moves closer to the lower plate 52. If multiple carrier tapes are being processed, the winding cylinder 53 extends and moves the upper plate 51 away from the lower plate 52. The distance between the upper plate 51 and the lower plate 52 can be adjusted according to the required width of the carrier tape. When the edge-fitting mechanism 33 moves and adjusts, the distance between the upper plate 51 and the lower plate 52 can be adjusted according to the adjustment position of the edge-fitting mechanism 33. When only one edge-fitting mechanism 33 is used to wind the carrier tape, the distance between the upper plate 51 and the lower plate 52 shrinks. The winding motor 54 drives the upper plate 51 and the lower plate 52 to rotate and wind the carrier tape. The winding units 5 all wind in a counterclockwise direction. When the three electric sliders 36 drive the three edge-fitting mechanisms 33 to move and wind multiple carrier tapes at the same time, the distance between the upper plate 51 and the lower plate 52 expands. The winding motor 54 drives the upper plate 51 and the lower plate 52 to rotate and wind the carrier tape. The winding units 5 all wind in a counterclockwise direction.

[0078] By installing water-cooling pipes 511 between the upper and lower reels 51 and 52, the carrier tape that has been wound up can be cooled. By symmetrically installing winding cylinders 53 in the middle of the lower reel 52, and installing winding connecting plates 55 at the output end of each winding cylinder 53, and connecting one side of the winding connecting plate 55 to the upper reel 51, the spacing between the upper reel 51 and the lower reel 52 can be adjusted according to the required width of the carrier tape.

[0079] In Example 2, during the winding process of a single or multiple carrier tapes, the carrier tape may become loose or misaligned. The carrier tape may not be wound in a circular shape, and during the winding process, some wound carrier tapes may have local gaps. These gaps may cause wrinkles or creases to appear on the carrier tape during winding. Loose winding of the carrier tape will result in defects in the final product. When the carrier tape is finally wound and needs to be cut, there will be a long section that is not wound. This section of the carrier tape may be misaligned during winding or may not be able to be wound into the reel as it rotates.

[0080] See Figures 8 to 17 Below the reel changing unit 4, a pressing unit 6 is installed. The pressing unit 6 can limit the winding of the carrier tape in the winding unit 5. The pressing unit 6 includes a pressing motor 61, which is installed on one side of the reel changing mounting plate 43. The output end of the pressing motor 61 penetrates the reel changing mounting plate 43 and is fitted with a sleeve rod 65. The sleeve rod 65 includes an installation end and an output end. A support rotating rod 62 is installed on one side of the installation end of the sleeve rod 65. The support rotating rod 62 rotates in the arc groove 44, which provides stable support for the sleeve rod 65 and prevents shaking during the pressing process, which could lead to gaps.

[0081] See Figures 8 to 17 A pressure cylinder 63 is installed on the side of the sleeve rod 65 away from the support rotating rod 62. A pressure connecting plate 64 is installed at the output end of the pressure cylinder 63. The pressure connecting plate 64 is connected to the output end of the sleeve rod 65. A pressure shaft 66 is installed on the output end of the sleeve rod 65. A pressure block 67 is installed on the pressure shaft 66. By setting the pressure shaft 66, the pressure block 67 can be easily disassembled. By replacing the pressure block 67 of different sizes, the number of carrier tapes can be limited, avoiding the problem of having to replace the equipment after changing the winding size of the carrier tape.

[0082] See Figures 11 to 15When the carrier tape begins to be wound in the winding unit 5, the pressure motor 61 rotates, driving the sleeve rod 65 to rotate. The sleeve rod 65 rotates to the side wall of the edge extension rod 332 to avoid interference with the edge application unit 3. The pressure cylinder 63 extends, driving the output end of the sleeve rod 65 to extend, and simultaneously driving the pressure block 67 to limit the carrier tape. After the cutting module 335 cuts the carrier tape, the pressure block 67 can still limit the carrier tape to prevent the wound carrier tape from falling off and to limit the winding of the unwound portion of the carrier tape.

[0083] By setting the pressure motor 61 to rotate, the sleeve rod 65 rotates. When the sleeve rod 65 rotates to the side wall of the edge extension rod 332, the pressure cylinder 63 extends, which drives the output end of the sleeve rod 65 to extend. Simultaneously, the pressure block 67 is driven to fit with the carrier belt, thus limiting the carrier belt. This achieves the effect of limiting the carrier belt during the winding process and limiting the winding of the cut portion of the carrier belt when winding is almost complete.

[0084] In Example 3, during the winding process of multiple carrier tapes, the sidewalls between the carrier tapes may stick together. When multiple carrier tapes are wound together, the heat in the middle part cannot be dissipated. This heat will cause the carrier tapes to stick together, and the excess heat will cause the carrier tapes to remain within the plastic temperature range, which will easily cause the carrier tapes to deform after winding.

[0085] See Figures 16 to 17 A cooling unit 7 is also provided on one side of the reel changing unit 4. The cooling unit 7 can cool the multiple carrier tapes when the winding unit 5 is winding them. The cooling unit 7 is located above the winding unit 5. The cooling unit 7 includes a cooling motor 71, which is installed on one side of the reel changing mounting plate 43. The output end of the cooling motor 71 penetrates the reel changing mounting plate 43 and is connected to a cooling sleeve rod 72. A cooling water cooling pipe 721 is installed in the middle of the cooling sleeve rod 72. A cooling cylinder 73 is installed on the cooling sleeve rod 72. A cooling connecting plate 74 is installed at the output end of the cooling motor 71 and is connected to the output end of the cooling sleeve rod 72.

[0086] When processing multiple carrier tapes, the cooling motor 71 rotates, driving the cooling sleeve rod 72 to rotate. The electric slider 36 moves on the slide rail 34, adjusting the position of the edge-fitting mechanism 33 so that the gap between the carrier tapes is the same as the thickness of the output end of the cooling sleeve rod 72. When multiple carrier tapes are wound up, the cooling sleeve rod 72 rotates to an angle that can be inserted into the gap between the carrier tapes. The cooling cylinder 73 drives the output end of the cooling sleeve rod 72 to extend. The cooling water cooling pipe 721 dissipates heat to the middle part of the carrier tape. After heat dissipation is completed, the upper plate 51 and the lower plate 52 move closer to each other to reduce the gap and reduce the distance between the carrier tapes.

[0087] By setting the cooling motor 71 to rotate and drive the cooling sleeve rod 72 to rotate, the cooling cylinder 73 drives the output end of the cooling sleeve rod 72 to extend, and the cooling water cooling pipe 721 dissipates heat to the middle part of the carrier belt, thus achieving the effect of heat dissipation to the middle part of the carrier belt.
