Description

Technical Field

[0001] This invention relates to an automatic carrier tape feeding and splicing control system, belonging to the field of carrier tape splicing technology. Background Technology

[0002] Currently, during the carrier tape dispensing process, the carrier tape reel is entirely manually changed. After one roll of carrier tape is used up, the empty reel (when the carrier tape is used up) and the take-up reel (when the empty reel is full) must be manually removed before replacing it with a new carrier tape reel. After the carrier tape reel and the empty take-up reel are replaced, the take-up isolation tape is manually wrapped around the empty take-up reel. The empty take-up reel is then manually rotated several times to expose the carrier tape, and then the carrier tape is attached to the previous carrier tape using adhesive tape. The attachment must ensure that the cutting accuracy error is controlled within 100um. Because the dispensing machine operates continuously, each reel of carrier tape can only be used for 20 minutes of production time, and the dispensing machine must be stopped every time a reel is changed. Therefore, personnel cannot leave the equipment for too long. Material replacement and tape connection work must be carried out every 20 minutes. Each dispensing machine must be equipped with a material replacement operator. There are a total of 9 dispensing machines in the workshop, and each one needs to be equipped with a corresponding material replacement operator. The labor cost is high, the work steps are numerous and the replacement is frequent. It is necessary to design a device to improve production efficiency and reduce the number of operators.

[0003] The document entitled "Carrier Tape Connecting Device" is published under the publication number CN111268484A. It is mainly for the situation of cutting and reconnecting damaged carrier tapes, and is not applicable to connecting carrier tapes on two carrier tape reels. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an automatic carrier belt feeding and splicing control system.

[0005] The automatic carrier belt feeding and splicing control system of the present invention includes:

[0006] The hopper section is used to hold the carrier tape reels.

[0007] Transfer section: Used to transfer the carrier tape within the hopper section between the hopper section and the guide section;

[0008] Guide section: Used to guide the carrier tape on the carrier reel to the splicing section;

[0009] Splicing section: Used to connect the carrier tapes on two carrier tape reels;

[0010] It also includes an industrial control computer: used to control the operation of the silo section, transfer section, guiding section and conveyor section.

[0011] The hopper section includes a storage rack for storing carrier tape reels, and the storage rack is provided with multiple storage slots corresponding to the carrier tape reels, with the carrier tape reels located in the storage slots;

[0012] Each storage slot is equipped with an induction switch for detecting whether there is a carrier tape reel in the slot and a thickness sensor for sensing the thickness of the corresponding carrier tape reel.

[0013] It also includes a moving mechanism for transferring the storage rack to the transfer section;

[0014] The inductive switch, thickness sensor, and drive mechanism are all connected to the industrial control computer.

[0015] The moving mechanism includes a support frame for supporting the storage rack, a guide rail on the support frame, and a slider corresponding to the guide rail on the storage rack. The storage rack is driven by a drive device to move the slider back and forth along the guide rail. Specifically, the drive device can be a push cylinder, with the push rod of the push cylinder parallel to the guide rail and the end of the push rod fixedly connected to the storage rack, thereby controlling the back and forth movement of the storage rack along the guide rail. The drive device can also be a motor-driven screw, with the screw parallel to the guide rail. The storage rack is threadedly connected to the screw via a slider, and the guide rail acts as a guide and limit, so that when the motor starts, the screw rotates with the motor shaft, thus ensuring that the storage rack can only move back and forth along the guide rail. The specific direction of movement is determined by the rotation direction of the screw.

[0016] The transfer section includes electrically operated grippers for gripping the carrier reel, which, via a transfer mechanism, clamps the carrier reel between the hopper section and the guide section. (Refer to...) Figure 1 and Figure 3 In this application, the hopper section is located below the transfer section, and the guide section is located on one side of both the hopper section and the transfer section. Based on this arrangement, the transfer mechanism in this application mainly includes movement in two directions, namely, vertical movement and horizontal movement.

[0017] The guiding part includes a fixed panel, and a set of guiding mechanisms are respectively provided on both sides of the fixed panel; a rotating mechanism for controlling the rotation of the fixed panel is provided at the bottom of the fixed panel.

[0018] The guiding mechanism includes two air shafts arranged opposite each other, a stripping guide device is provided between the two air shafts, and each air shaft is driven by a motor.

[0019] In use, the transfer section is equipped with a position sensor that senses the position of the air shaft. The transfer section places a carrier reel with carrier tape on the upper air shaft and an empty reel on the lower air shaft. After the carrier reel is moved into the air shaft, the air shaft inflates to fix the carrier reel in place, and the carrier reel rotates with the air shaft controlled by a motor. Subsequently, as the motor rotates, the carrier reel with carrier tape gradually releases the carrier tape. A peeling guide device separates the carrier tape from the winding on the carrier reel and guides the separated carrier tape to the tape receiving section.

[0020] The stripping guide device includes a carrier belt access rail, a guide rod is provided above one end of the carrier belt access rail near the air shaft, a rotary motor is driven to the carrier belt access rail, and an electric guide rail for driving the rotary motor to move is provided on the fixed panel.

[0021] A winding suction nozzle is provided on the side of the carrier tape access rail near the air expansion shaft. The winding suction nozzle moves back and forth between the two air expansion shafts via a lifting and telescopic device.

[0022] The rotating mechanism includes a rotating base fixedly connected to the bottom of the fixed panel, and the rotating base is driven by a motor.

[0023] The tape-connecting part includes a tape-adhesive mechanism, and a tape-connecting track is provided under the tape-adhesive mechanism; wherein one end of the tape-connecting track is connected to the carrier tape access rail, and the other end of the tape-connecting track is connected to the carrier tape operation equipment.

[0024] The tape-attaching mechanism has a sensor for sensing the carrier tape installed on the tape-attaching track near the guide section.

[0025] The tape application mechanism includes a tape roll fixedly disposed on one side of the tape receiving track, and a guide roller is disposed on the side of the tape roll near the tape receiving track;

[0026] It also includes a telescopic clamp fixedly installed on the other side of the connecting track, the telescopic clamp facing the guide roller;

[0027] A telescopic cylinder is provided between the guide roller and the telescopic clamp. A pressure plate is fixedly connected to the telescopic part of the telescopic cylinder. The pressure plate is located directly above the connecting track. Slices are fixedly provided on both sides of the pressure plate.

[0028] The beneficial effects of this invention compared to the prior art are:

[0029] The automatic carrier belt feeding and splicing control system described in this invention realizes the automated operation from changing material trays to splicing belts. The splicing and material changing processes can run uninterruptedly. The relevant carrier belt running equipment (such as dispensing machines) does not need to be stopped to wait for material changes, thereby realizing downtime-free operation, improving work efficiency, reducing labor costs, and saving material change time.

[0035] The present invention will be further described below with reference to specific embodiments.

[0036] However, the description of the present invention is merely a structural or even functional description of the embodiments, and the scope of the present invention is not limited by the embodiments described herein.

[0037] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of the present invention includes equivalents that can realize the technical concept.

[0038] like Figures 1-4 As shown, the carrier belt automatic feeding and splicing control system includes

[0039] The hopper section is used to hold the carrier tape reel 1.

[0040] Transfer section: Used to transfer the carrier tape 1 within the hopper section between the hopper section and the guide section;

[0041] Guide section: Used to guide the carrier tape on carrier reel 1 to the splicing section;

[0042] The tape splicing section is used to connect the carrier tapes on the two carrier tape reels 1.

[0043] It also includes an industrial control computer: used to control the operation of the silo section, transfer section, guiding section and conveyor section.

[0044] The hopper section includes a storage rack 2 for storing the carrier tape 1. The storage rack 2 is provided with multiple storage slots 3 corresponding to the carrier tape 1, and the carrier tape 1 is located in the storage slots 3.

[0045] Each storage slot 3 is equipped with an induction switch for detecting whether there is a carrier tape 1 in the slot and a thickness sensor for sensing the thickness of the corresponding carrier tape 1.

[0046] It also includes a moving mechanism for transferring the storage rack 2 to the transfer section;

[0047] The inductive switch, thickness sensor, and drive mechanism are all connected to the industrial control computer.

[0048] In this application, the storage rack 2 can store multiple carrier reels 1, allowing workers to perform material loading operations. A thickness sensor can also determine whether a reel in the tank contains carrier tape or is empty. Based on the sensing results from the inductive switch and the thickness sensor, the industrial control computer controls the moving mechanism to move the corresponding storage tank 3 to the transfer section, facilitating the transfer section to pick up or place the carrier reel 1.

[0049] In this embodiment, the fixing frame 8 is set as a cuboid frame, and the hopper part is set in the inner cavity of the cuboid frame.

[0050] The moving mechanism includes a support frame 4 for supporting the storage rack 2. A guide rail 5 is provided on the support frame 4, and a slider 6 is provided on the storage rack 2 corresponding to the guide rail 5. The storage rack 2 is driven by a driving device to move the slider 6 back and forth along the guide rail 5. Specifically, the driving device can be a push cylinder, with its push rod parallel to the guide rail 5 and its end fixedly connected to the storage rack 2, thereby controlling the back and forth movement of the storage rack 2 along the guide rail 5. Alternatively, the driving device can be a motor-driven screw, with the screw parallel to the guide rail 5. The storage rack 2 is threadedly connected to the screw via a slider 6. The guide rail 5 acts as a guide and limiter, ensuring that when the motor starts, the screw rotates with the motor shaft, allowing the storage rack 2 to move only back and forth along the guide rail 5. The specific direction of movement is determined by the rotation direction of the screw.

[0051] The transfer section includes an electrically operated gripper 7 for gripping the carrier reel 1, which clamps the carrier reel 1 between the hopper section and the guide section via a transfer mechanism. (Refer to...) Figure 1 and Figure 2 In this application, the hopper section is located below the transfer section, and the guide section is located on one side of both the hopper section and the transfer section. Based on this arrangement, the transfer mechanism in this application mainly includes movement in two directions, namely, vertical movement and horizontal movement.

[0052] Specifically, in this embodiment, for ease of movement, the hopper section, transfer section, guiding section, and connecting section are all uniformly mounted on the fixed frame 8. The transfer mechanism includes a horizontal fixed frame 10 mounted above the fixed frame 8; a vertical fixed frame 9 is fixedly connected above the horizontal fixed frame 10, and a vertical drive mechanism is provided on the vertical fixed frame 9 to drive the electric gripper 7 to move up and down along the vertical fixed frame 9; a horizontal drive mechanism is provided above the fixed frame 8 to drive the horizontal fixed frame 10 to move back and forth along the top frame of the fixed frame 8. The specific structure of the vertical drive mechanism and the horizontal drive mechanism can be referenced from the drive device of the hopper section, and can be a cylinder drive or a motor and screw drive. If a motor and screw drive is used, guide rails are respectively provided on the top frame of the fixed frame 8 and the frame of the vertical fixed frame 9, so that the electric gripper 7 moves along the corresponding guide rails to achieve the guiding and limiting function.

[0053] The guide portion includes a fixed panel 11, and a set of guide mechanisms are respectively provided on both sides of the fixed panel 11;

[0054] The bottom of the fixed panel 11 is provided with a rotation mechanism for controlling the rotation of the fixed panel 11.

[0055] The guiding mechanism includes two air shafts 12 arranged opposite to each other, a stripping guide device is provided between the two air shafts 12, and each of the two air shafts 12 is drivenly connected to a motor.

[0056] In use, the transfer section is equipped with a position sensor that senses the position of the air shaft 12. The transfer section places the carrier reel 1 with the carrier tape on the upper air shaft 12 and the empty reel on the lower air shaft 12. After the carrier reel 1 moves into the air shaft 12, the air shaft 12 is inflated to fix the carrier reel 1. The carrier reel 1 is rotated with the air shaft 12 by the motor.

[0057] Subsequently, the motor rotates, and the carrier tape reel 1 with the carrier tape gradually releases the carrier tape. The carrier tape on the carrier tape reel 1 is separated from the winding by the peeling guide device, and the separated carrier tape is guided to the tape splicing part.

[0058] The stripping guide device includes a carrier belt access rail 13, and a guide rod 14 is provided above one end of the carrier belt access rail 13 near the air expansion shaft 12. The carrier belt access rail 13 is connected to a rotary motor, and an electric guide rail 22 for driving the rotary motor to move is provided on the fixed panel 11.

[0059] A winding suction nozzle is provided on the side of the carrier belt access rail 13 near the air expansion shaft 12. The winding suction nozzle moves back and forth between the two air expansion shafts 12 via a lifting and telescopic device. In this embodiment, the lifting and telescopic device includes an electric cylinder. The telescopic end of the electric cylinder is fixedly connected to the winding suction nozzle. The electric cylinder is fixedly connected to a lifting device, which can be an existing device capable of linear motion, such as a screw jack. (Refer to...) Figures 1-3 The upper air shaft 12 drives the carrier reel 1 to rotate. The winding on the carrier reel 1 releases its end, which droops due to gravity. The winding suction nozzle is equipped with a sensor to sense the winding. When winding is sensed, the electric cylinder pushes the winding suction nozzle to move in the winding direction, adsorbing the winding. Then, the lifting device moves the electric cylinder down to the empty reel. The surface of the empty reel's shaft is adhesive. The electric cylinder pushes the winding suction nozzle towards the shaft of the empty reel, adhering the winding. Subsequently, the air shaft 12 drives the empty reel to rotate, and the winding winds onto the empty reel. Since the positions of the two air shafts 12 are fixed, the lifting device can be set to the lowest position, with the winding suction nozzle facing the empty reel's shaft, and to the highest position, with the winding suction nozzle facing the guide rod 14. Alternatively, sensors that sense the empty reel's shaft and guide rod 14 can be installed on the lifting device to achieve correspondence between the winding suction nozzle and the empty reel's shaft.

[0060] After the carrier tape is wound a certain distance on the empty reel, it will slowly leak out. At this point, the winding suction nozzle returns to the guide rod 14, and the electric cylinder extends to push the winding towards the guide rod 14. The carrier tape follows the guide rod 14 into the carrier tape access rail 13, achieving separation of the carrier tape from the winding. During this process, the rotating standby mechanism drives the carrier tape access rail 13 to rotate at a set angle, which, combined with the guide rod 14, ensures that the carrier tape enters correctly.

[0061] A set of guiding mechanisms is provided on each of the two sides of the fixed panel 11. After the guiding mechanism on one side completes the guiding of the starting part of the carrier belt to the carrier belt access rail 13, the rotating mechanism controls the fixed panel 11 to rotate. The guiding mechanism on one side docks with the receiving part to perform the receiving operation of the carrier belt end. On the other side, the transfer part removes the take-up reel and empty reel, replaces it with a new carrier belt reel and empty reel, and continues to guide the starting part of the carrier belt to the carrier belt access rail 13.

[0062] The rotating mechanism includes a rotating base 21 fixedly connected to the bottom of the fixed panel 11, and the rotating base 21 is connected to a motor. The motor is fixed on the fixed frame 8 and drives the fixed panel 11 to rotate.

[0063] Reference Figure 4 The tape-connecting part includes a tape-adhesive mechanism, and a tape-connecting track 15 is provided under the tape-adhesive mechanism;

[0064] One end of the connecting track 15 is connected to the carrier belt access track 13, and the other end of the connecting track 15 is connected to the carrier belt operation equipment (such as dispensing equipment).

[0065] A sensor for sensing the carrier tape is installed on the tape receiving track 15 near the guide section of the tape pasting mechanism.

[0066] The tape application mechanism includes a tape roll 16 fixedly disposed on one side of the tape receiving track 15, and a guide roller 17 disposed on the side of the tape roll 16 near the tape receiving track 15.

[0067] It also includes a telescopic clamp 18 fixedly installed on the other side of the connecting track 15, the telescopic clamp 18 being directly opposite the guide roller 17;

[0068] A telescopic cylinder 19 is provided between the guide roller 17 and the telescopic clamp 18. A pressure plate 20 is fixedly connected to the telescopic part of the telescopic cylinder 19. The pressure plate 20 is located directly above the connecting track 15. Slices are fixedly provided on both sides of the pressure plate 20.

[0069] The carrier tape moves along the connecting track 15, and its end and start are both sensed by sensors. Since the length of the connecting track 15 and the position of the tape pasting mechanism are fixed, the industrial control computer can control the moving speed of the carrier tape so that the end of the previous carrier tape and the start of the next carrier tape meet directly below the pressure plate 20. The tape is placed on the tape roll 16, and a part of the tape is temporarily pasted to the guide roller 17. The telescopic clamp 18 extends, clamps the tape and pulls it out. Then the telescopic cylinder 19 drives the pressure plate 19 to press down and paste the tape to the junction of the two carrier tapes. Then the slicer cuts off the pasted tape, completing the connection and pasting of the two carrier tapes.

[0070] This enables automatic material changing of carrier tape reels and automatic connection between carrier tapes, freeing up labor.

[0071] Of course, the above description is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is also not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of the present invention should fall within the patent coverage of the present invention.
