Description

Electronic component continuous tape and reel equipment and its method for achieving fully automatic continuous tape and reel. Technical Field

[0001] This invention relates to the technical field of automatic assembly and packaging processes for electronic components, and particularly to a fully automatic tape and reel equipment and its precise control method for realizing continuous automatic heat sealing, cutting and reel storage of tapes after electronic component assembly. Background Technology

[0002] Previous automated devices and manufacturing methods for taped and reeled electronic components, such as the crystal automatic testing and packaging machine (CN101499430B), the multi-station integrated crystal oscillator equipment (CN107499563B), and the manufacturing device and method for serial taped and reeled electronic components (CN104773317B), could only distinguish between "good" and "defective" products. They then used a vision system to determine the orientation and surface condition of the components, taping and reeling the good products and placing the defective ones in a recycling area. Even after completing a certain number of taped and reeled products, these devices still required manual reel changing before the next reel could be produced.

[0003] Taking a typical reel containing 1000 crystal oscillators as an example, this type of equipment can usually complete the winding and packaging within 30 minutes, as shown in Figure 1. However, after completing the winding of the required number of reels, a 30-40 cm blank section needs to be reserved on the carrier tape, and an additional 60-100 cm needs to be left at the end of the top sealing tape for winding, followed by securing with sealing tape. These steps all require manual operation and cannot be automated. Relying on manual reel changing not only reduces the level of automation but also presents numerous problems.

[0004] First, downtime disrupts the continuous operation of the testing equipment, and some testing modules require re-calibration and zeroing upon restarting, reducing testing efficiency and increasing the frequency of failures. Second, manual operation is prone to delays, leading to excessive downtime and increased energy consumption. Finally, it cannot achieve 24 / 7 unattended automatic operation, limiting further optimization of production capacity. Therefore, developing a fully automatic tape changing mechanism capable of automatically cutting tape, precisely controlling tape length, and automatically bending and pasting is an important way to achieve high-efficiency continuous production.

[0005] In conclusion, developing new fully automated electronic component testing, packaging, and reel-changing equipment to achieve unattended continuous production is a crucial direction for improving both production capacity and quality. This requires solving key technical challenges such as automatic tape cutting, tape length control, and automatic bending and pasting. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a continuous tape and reel device for electronic components. By incorporating a multi-reel automatic winding mechanism, a precise carrier tape control structure, and a high-speed, accurate carrier tape switching mechanism, it achieves automated operation and efficient, stable operation throughout the entire tape and reel process.

[0007] The objective of this invention is achieved through the following technical solution: a continuous tape and reel device for electronic components, comprising: a support plane for component mounting; a support frame supporting the support plane; a carrier tape feeding device fixed below the support plane; a carrier tape guiding device fixed on the support plane and arranged along the setting direction of the carrier tape feeding device; a covering film feeding device and a carrier tape heat sealing mechanism arranged above the carrier tape guiding device; a carrier tape transmission drive device for driving the carrier tape; a multi-reel automatic winding mechanism arranged at the end of the carrier tape guiding device; and a covering film pre-winding mechanism, a sealing tape feeding device, and a cutting mechanism arranged between the carrier tape guiding device and the multi-reel automatic winding mechanism.

[0008] Preferably, the carrier tape guiding device includes a linear guide rail and a linear motor; the heat sealing head of the carrier tape heat sealing mechanism employs PID temperature control. The use of a linear motor and PID temperature control enables precise control of carrier tape transmission and heat sealing, improving equipment stability.

[0009] Preferably, the drive systems for the carrier tape feeding device, the carrier tape guiding device, the multi-reel automatic winding mechanism, and the carrier tape heat sealing mechanism all employ closed-loop control. The closed-loop control drive system adjusts system parameters in real time, improving control accuracy.

[0010] Preferably, the multi-reel automatic winding mechanism includes a frame, a rotating base rotatably mounted on the frame, a reel mounting plate centrally connected to the rotation axis of the rotating base and slidable relative to the rotating base, and a limiting system disposed on both sides of the reel mounting plate to limit the sliding range. The rotating base and sliding reel design allow for reel position adjustment, facilitating carrier tape storage. The limiting system ensures accurate storage.

[0011] Preferably, the pre-shearing mechanism for the coating film includes a vertically fixed transmission assembly, a slide that can move vertically along the transmission assembly, and an execution base connected to the slide; the execution base has at least two fixed rollers and at least one movable roller that can move vertically between the two fixed rollers. The pre-shearing mechanism for the coating film uses a slide and movable roller structure to achieve high-speed pre-shearing of the coating film, preparing it for subsequent packaging.

[0012] Preferably, the sealing tape feeding device includes a fixed base fixed to the frame, a movable base hinged to the fixed base, a tape reel rotatably connected to the movable base, and a tape unfolding and pushing assembly fixed to the movable base. The sealing tape feeding device adopts a swing structure, which can accurately unfold the tape and adhere it to the film-coated end.

[0013] Preferably, the pushing assembly includes: a plate with one end fixed to a movable base and the other end extending in the width direction of the tape; a rolling rod located below the plate, with one end fixed to the movable base and the other end extending in the width direction of the tape beyond the tape width; a pushing cylinder fixed to the plate; and a suction cup seat mounted on the free end of the piston rod of the pushing cylinder, with at least one suction cup on the suction cup seat. The pushing assembly uses a cylinder-driven suction cup structure, which can precisely control the tape unfolding length and ensure reliable adhesion between the tape and the coating.

[0014] Preferably, the tape unfolding and pushing component of the sealing tape feeding device is equipped with a baffle strip with a nozzle. The baffle strip is made of non-stick material, and its main body is set on the rolling rod, with the air passage of the nozzle located inside the baffle strip. This baffle strip and nozzle design optimizes the tape application process and makes the suction cup more reliable.

[0015] Preferably, the cutting mechanism employs a flying cutter system comprising two sets of flying cutters, which sequentially cut the carrier tape. This flying cutter system achieves high-speed, precise cutting of the carrier tape, ensuring subsequent packaging quality.

[0016] Preferably, the multi-reel automatic winding mechanism has an outer pressure roller at the winding station. This outer pressure roller applies pressure to the outermost edge of the carrier tape via a spring or cylinder to prevent the carrier tape from springing back during winding and to firmly press the adhesive application area after the tape is applied. The outer pressure roller prevents the winding from springing back and firmly presses the adhesive tape application area.

[0017] To address the aforementioned problems, this invention provides a method for fully automated continuous tape feeding using the aforementioned equipment, characterized by comprising the following steps:

[0018] 1) Load the electronic components onto the carrier tape;

[0019] 2) The carrier belt feeding device feeds the carrier belt;

[0020] 3) The carrier belt guiding device guides the carrier belt;

[0021] 4) The carrier tape transmission drive device, one reel of the multi-reel automatic winding mechanism, and the carrier tape heat sealing mechanism operate synchronously to transmit, heat-press seal, and wind up the carrier tape containing electronic components;

[0022] 5) After the set quantity of hot-pressed packaging is reached, a section of empty strip is left. When this empty strip is transferred between the multi-reel automatic winding mechanism and the carrier tape guide device, the reel in the multi-reel automatic winding mechanism stops moving;

[0023] 6) The carrier tape transmission drive device continues transmission, and the carrier tape separates from the covering film material;

[0024] 7) The actuator in the pre-shearing mechanism of the covering film material quickly lifts and pre-shears the covering film material upwards, and the pre-shearing length can wrap around the strip reel more than once;

[0025] 8) The cutting mechanism cuts the carrier tape, the reel quickly winds up, the covering film material pre-winding mechanism slows down in coordination with the reel winding speed until all the pre-wound covering film material is wound up, the covering film material pre-winding mechanism moves away from the covering film material, and the cutting mechanism cuts off the covering film material;

[0026] 9) The actuating part of the sealing tape feeding device adheres the sealing tape to the end of the cut-off cover film material, and unfolds a certain length of tape by swinging, while the reel continues to wind up until the tape and cover film material meet the bonding length required for sealing; at the same time, the carrier tape gradually lengthens under transmission;

[0027] 10) The cutting mechanism cuts off the sealing tape, and the execution part of the sealing tape feeding device is reset; the multi-reel automatic winding mechanism rotates as a whole, and the reel that has completed the sealing moves away from the winding position so that a new empty reel can be replaced by a robotic arm, etc.; the other empty reel approaches the end of the cut carrier tape, and through the cooperation of the sensor and the reel rotation, the end of the carrier tape enters the hole in the reel for receiving the end of the carrier tape, and the reel starts to rotate to start a new winding operation. The multi-reel automatic winding mechanism rotates as a whole, and the reel that has entered the winding operation moves to the winding position.

[0028] Preferably, in step 4, a guide slot plate is fixedly installed on the side of the frame of the multi-reel automatic winding mechanism.

[0029] Preferably, the guide slot plate has an elongated hole, the long side of which extends along the sliding direction of the carrier belt. A guide auxiliary push cylinder and a negative pressure suction head are provided below the guide slot plate. The suction head's range of motion is within the elongated hole. When the carrier belt slides down to near the empty reel hole, the suction head holds the carrier belt, and the push cylinder pushes the carrier belt to move, so that the carrier belt accurately aligns and enters the empty reel hole.

[0030] This method details the specific workflow for the equipment to achieve fully automated continuous tape production, and sequentializes key steps such as carrier tape transmission, heat sealing, winding, cutting, pre-winding of the cover film, and application of sealing tape. It clarifies the detailed technical process of automated roll changing, which is conducive to understanding and applying this invention to achieve high-speed and precise fully automated continuous tape production.

[0031] In summary, the present invention has the following advantages compared with the prior art:

[0032] 1. The multi-reel automatic winding mechanism enables automatic switching and rewinding of carrier tapes, automating the entire tape feeding process and reducing the risks associated with manual operation.

[0033] 2. A precise control structure for carrier tape transmission was set up, including a linear motor, a PID temperature-controlled heat sealing head, and a closed-loop control drive system, which improved the accuracy and stability of carrier tape transmission and heat sealing.

[0034] 3. A high-speed and accurate carrier tape switching mechanism was designed, including a pre-shrinking mechanism for the covering film, a sealing tape feeding device, and a flying cut system, which can realize high-speed and stable switching of carrier tapes.

[0035] 4. The multi-reel winding mechanism with a swivel sliding design facilitates the loading, unloading, and positioning of unloaded reels, enhancing the level of automation.

[0036] 5. Various auxiliary devices, such as a limit system, external pressure rollers, optimized tape feeding structure, and carrier tape guiding mechanism, are installed to ensure the accuracy of carrier tape storage, packaging, and switching.

[0037] In summary, this invention achieves full automation of the tape-making process, significantly reducing manual operations, improving efficiency, and minimizing the risk of human error. Simultaneously, the adoption of various precise control, transmission, and switching mechanisms ensures high-speed, stable operation and product quality throughout the entire automated tape-making process. Overall, this invention greatly enhances the automation level and work efficiency of tape-making devices. Attached Figure Description

Detailed Implementation

[0050] The present invention will now be further described with reference to the embodiments illustrated in all the accompanying drawings:

[0051] Example 1

[0052] This technical solution proposes a continuous tape and reel device for electronic components, as shown in Figure 2. For ease of explanation, a coordinate system is defined: the Z-axis represents the direction of gravity, and the X-axis and Y-axis define two directions on the horizontal plane; the three axes are orthogonal. In the following description, the direction parallel to the Y-axis will also be referred to as the "depth direction Y," and the direction parallel to the Z-axis will be referred to as the "vertical direction Z."

[0053] The device includes: a support plane 1 for component mounting; and a support frame 11 that supports the support plane.

[0054] The system includes: a carrier tape feeding device 2 fixed below the supporting plane; a carrier tape guiding device 3 fixed on the supporting plane and laid along the carrier tape travel path; a covering film feeding device 4 and a carrier tape heat sealing mechanism 5 mounted above the carrier tape guiding device; a carrier tape transmission drive device 6; and a winding device 7 arranged linearly with the carrier tape guiding device 3 for carrier tape winding. The feeding of the covering film feeding device 4 is synchronized with the movement of the carrier tape after heat sealing.

[0055] Key structural improvements were focused on the carrier tape conveying and winding mechanisms. Figure 1 shows the completed carrier tape reel, including carrier tape reel 01, carrier tape 02, covering film 03, and sealing tape 04. The tape is not pasted on for easy observation.

[0056] Based on this, the improvements are as follows: the original winding device 7 is replaced with a multi-reel automatic winding mechanism 70 to achieve automatic roll changing, and a pre-winding mechanism 80 for the covering film material, a sealing tape feeding device 90 and a cutting mechanism 100 are set between the winding device and the guiding device.

[0057] The pre-shearing mechanism 80 allows the lifting position of its actuator to be set arbitrarily within the reachable range; the cutting mechanism 100 allows the position of its actuator to be arbitrarily reachable at the required positions on the X, Y, and Z axes; and the sealing tape feeding device 90 allows its actuator to drag the sealing tape to contact and adhere to the film material.

[0058] These newly added devices and mechanisms work in conjunction with existing conveying power devices, heat sealing mechanisms, and other modules to achieve fully automated packaging and winding.

[0059] Specific workflow:

[0060] Step 1: Qualified electronic components that have completed testing are placed onto the carrier tape by the electronic component transfer and orientation device;

[0061] Step 2: The carrier tape transmission drive device 6 and one of the reels of the multi-reel automatic winding mechanism 70, along with the carrier tape heat sealing mechanism 5, operate synchronously to simultaneously transmit, heat-seal, and wind up the carrier tape containing electronic components.

[0062] Step 3: After the set quantity of heat-pressed packaging is reached, leave an empty space of about 30 cm for the carrier tape. When this empty space of carrier tape is transferred between the reel and the carrier tape guide device 3, the reel stops moving.

[0063] Step 4: The carrier tape transmission drive device 6 continues transmission (therefore, the carrier tape will be in a state of separation from the covering film material as shown in Figure 3, and the space where the two are separated provides space for the covering film material pre-shrinking mechanism 80 to enter);

[0064] Step 5: The actuator of the film covering material pre-shrinking mechanism 80 quickly lifts the film covering material upwards to pre-shrink it to a length that can wrap around the carrier tape reel 1.5 times. The state after lifting is shown in Figure 2.

[0065] Step 6: The cutting mechanism 100 cuts the carrier tape, the reel quickly winds up, the covering film material pre-winding mechanism 80 decreases its winding speed in coordination with the reel until all the pre-wound covering film material is wound up, the covering film material pre-winding mechanism 80 moves away from the covering film material, and the cutting mechanism 100 cuts off the covering film material.

[0066] Step 7: The actuating part of the sealing tape feeding device 90 adheres the sealing tape to the cut end of the covering film material. The sealing tape feeding device 90 unfolds a certain length of tape by swinging, and the reel continues to rewind until the tape and covering film material are pasted to the required length to meet the sealing requirements.

[0067] At the same time, the truncated carrier tape gradually lengthens during transmission;

[0068] Step 8: The cutting mechanism 100 cuts the sealing tape, and the execution part of the sealing tape feeding device 90 resets; the multi-reel automatic winding mechanism 70 rotates as a whole, and the sealed reel moves away from the winding position so that it can be replaced with a new empty reel by means of other means such as a robotic arm with a suction cup, while the empty reel at the other end approaches the end of the cut carrier tape (all known reels have at least one hole for receiving the end of the carrier tape). By setting a sensor and cooperating with the rotation of the reel, the end of the carrier tape enters the hole, and the reel is started to rotate to start a new winding operation. The multi-reel automatic winding mechanism 70 rotates as a whole to bring the reel that entered the winding operation to the normal winding position.

[0069] This dual-reel design solves the problem of traditional single-reel designs requiring machine downtime for reel replacement, and achieves automated packaging and rewinding processes, significantly improving automation levels and work efficiency, enabling true continuous production.

[0070] Regarding the multi-reel automatic winding mechanism 70, this embodiment uses two reels as an example, but in actual applications it is not limited to two reels. The specific structure is further refined as follows: it includes a frame 71 for providing support for the device, a rotatable rotating base 72 mounted in the frame, and a reel mounting plate 73 centered on the axis of rotation of the rotating base, abutting or parallel to the large surface of the rotating base, and slidable relative to the rotating base. The length dimension of the reel mounting plate must be able to accommodate two reels, and the centers of one side of the two reel plates are in the same plane, and this plane is on the same plane as the center of the width direction of the carrier tape. The sliding position of the reel mounting plate 73 is limited in this embodiment by setting multiple limiting pulleys 731 on both sides of the length direction to abut against each other.

[0071] The purpose of making the reel mounting plate 73 slidable is twofold. Firstly, when applying sealing tape in step seven, the sliding of the reel mounting plate 73 can change the distance and angle with the sealing tape feeding device 90, thereby allowing for more flexible cooperation and reliable bonding. Secondly, in step eight, when the end of the carrier tape aligns with the reel hole, if the alignment is not complete and the length of the carrier tape extending downwards has already exceeded the hole, the reel mounting plate 73 can slide downwards as a whole to bring the end of the carrier tape back above the hole, thus completing the connection.

[0072] Therefore, an elongated hole 732 is provided in the middle of the reel mounting plate 73 at a certain angle to the length direction of the mounting plate. A variable diameter or other pressing member 733 that can change the contact point and center distance is provided in the elongated hole. By providing power to make the pressing member rotate, the reel mounting plate 73 is in different positions when it rotates to different positions.

[0073] Referring to Figure 6, the specific structure of the film pre-recruiting mechanism 80 includes: a vertically arranged transmission assembly (not shown) fixed to the frame 71; a slide 82 that travels along the transmission path of the transmission assembly; an execution base 83 located on one side of the working surface of the slide 82; a push cylinder 84 whose main body is fixed to the slide 82 and whose piston rod free end is fixed to the execution base 83; and a roller 85 fixedly mounted on the execution base 83. The movement path of the push cylinder 84 is in the depth direction. The power source of the slide 82 is not shown in the figure. It pushes the slide 82 to rise and fall so that the roller 85 matches the film in the height direction, while the push cylinder 84 matches the roller 85 with the film in the depth direction. With the coordinated cooperation of the two power sources, the pre-recruiting and releasing of the film are completed, thereby ensuring continuous operation of the equipment.

[0074] To reduce the travel distance of the slide during pre-shearing of the covering film, this invention optimizes the roller configuration of the pre-shearing mechanism to include at least two fixed rollers 851 and at least one movable roller 852, with sufficient spacing between the two fixed rollers to allow the movable roller to pass through. The movable roller is driven by a power assembly 853. During operation, the movable roller is positioned below the two fixed rollers, leaving a gap for the covering film to enter. As the slide moves upward, the power assembly drives the movable roller downward, thus completing the pre-shearing of the covering film while reducing the slide's lifting height. When the equipment operates continuously at high speed, shortening the lifting and taking-up time and space is crucial. This optimization significantly reduces the slide's working stroke and the power assembly's driving stroke, improving work efficiency. Furthermore, the multiple rollers increase the contact area with the covering film, further stabilizing the pre-shearing process. This optimization improves the efficiency and reliability of the pre-shearing mechanism.

[0075] Referring to Figure 5, the specific structure of the sealing tape feeding device 90 includes:

[0076] A fixing seat 91 is fixed on the frame 71;

[0077] A movable seat 92 is provided that is hinged to the fixed seat 91 and can be easily attached and detached from the tape reel. During the rotation of the movable seat 92, the position of the tape reel is higher than the position when the carrier tape is normally wound up.

[0078] The power unit (not shown in the figure) is connected to the movable seat 92 via a transmission.

[0079] A push assembly 93 is used to fix the starting end of the tape and extend it forward to unfold the tape. Referring to Figures 7-8, the push assembly 93 includes: a plate 931 with one end fixed to a movable base 92 and the other end extending in the width direction of the tape; a rolling rod 932 located below the plate 931, with one end fixed to the movable base 92 and the other end extending in the width direction of the tape beyond the tape width; the rolling rod 932 is made of a non-stick material, such as silicone or polytetrafluoroethylene; a push cylinder 933 fixed to the plate 931; and a suction cup seat 934 mounted on the free end of the piston rod of the push cylinder. The suction cup seat has at least one suction cup 935, with the suction port facing downwards, i.e., towards the back of the tape. For first-time use, the starting end of the new tape needs to be manually pushed past the rolling rod to below the suction cup. During operation, the suction cup uses negative pressure to lift the back of the tape, making the adhesive surface face outwards for easy contact with the covering film. The push cylinder can flexibly push the tape length. The non-stick rolling rod prevents the tape from sticking. This optimization scheme makes the push component unfold the tape more stably and reliably, and also makes it easier for first-time use.

[0080] To facilitate tape pickup by the suction cup, a nozzle-equipped baffle 936 is installed on the adhesive surface of the tape. The baffle is made of non-stick material, with its main body mounted on the rolling rod, and the air passage for the nozzle located inside the baffle. This way, after one application, the tape falls onto the baffle, bringing the suction nozzle closer to the tape and improving adhesion. Furthermore, the airflow from the nozzle blows the tape towards the suction nozzle, making adhesion even easier. The nozzle design on the baffle makes the tape pickup process smoother and more reliable, further improving the stability of the sealing and feeding process. At the winding station of the multi-reel automatic winding mechanism 70, an outer pressure roller 200 is provided. During winding, the outer pressure roller 200 is held at the outermost edge of the carrier tape by a power device such as a spring or cylinder (not shown in the figure) to prevent the carrier tape from springing back. It also serves to compact the adhesive area after tape application.

[0081] A tensioning mechanism 300 is provided between the carrier tape drive unit 6 and the multi-reel automatic winding mechanism 70. Below the tensioning mechanism 300 is a pressure roller 400 that can be moved away from or closer to the carrier tape; the pressure roller is powered by a cylinder (not shown in the figure). The pressure roller is used to temporarily fix the carrier tape or to increase the friction of the carrier tape by clamping it. For example, it is used to fix the carrier tape from the covering film in step four of the workflow, or to maintain tension on the covering film after cutting in step seven, which is beneficial for winding and tape application.

[0082] Referring to Figure 9, a guide slot plate 500 is fixedly installed on the side of the frame 71 to facilitate the entry of the cut carrier tape into the hole of the empty reel. After falling, the carrier tape slides down along the guide slot plate to accurately align with the hole of the empty reel. To further control the guidance of the carrier tape, an elongated hole 501 is provided on the side of the guide slot plate 500 near the reel, with the long side of the elongated hole 501 extending in the direction of the carrier tape's sliding. A guide auxiliary push cylinder 502 is installed below the guide slot plate 500, and a negative pressure suction head 503 is mounted on the cylinder, with the suction head's range of motion located within the elongated hole 501. When the carrier tape slides down close to the reel hole, the suction head holds the carrier tape, and the push cylinder moves it, giving the flexible carrier tape a certain rigidity and a controllable forward speed, which is crucial for correctly entering the reel hole. This optimized carrier tape guidance scheme allows the carrier tape to accurately and controllably enter the empty reel during the cut-and-reload process, avoiding reload failures caused by errors.

[0083] The present invention also has further optimized and refined solutions, specifically as follows:

[0084] 1. In step one, considering that electronic components of different models and batches may have slight differences in size and positioning hole positions, the electronic component transfer and orientation device can be designed with multiple replaceable gripping heads. The appropriate gripping head can be selected based on the actual type of electronic component. The vacuum adsorption system for the gripping head to adsorb electronic components also needs to be designed with different adsorption surface shapes.

[0085] 2. In step two, the carrier belt power unit 6 can be driven by a servo motor, in conjunction with an encoder, to achieve closed-loop control of the carrier belt's movement speed and position, ensuring the stability of the carrier belt's movement. A similar closed-loop control method is also used for the rotation speed control of the take-up reel. The temperature of the heat-sealing head of the heat-sealing mechanism 5 needs precise control; an independent temperature control loop can be designed.

[0086] 3. In step three, the control system, combined with the encoder feedback signal, can calculate the distance the carrier belt has moved, thereby accurately locating the length of the empty carrier belt. The position of the empty carrier belt segment entering between the reel and the guide device 3 can also be detected by a photoelectric sensor.

[0087] 4. In step five, the actuator of the pre-shrinking mechanism 80 can be designed to be driven by a pneumatic cylinder or a servo motor. During the lifting process, the torque or pressure also needs to be controlled to prevent damage to the film material.

[0088] 5. In step six, if the pre-wound length of the covering film is slightly insufficient, a belt sensor can be set to give an early warning when the covering film is about to be completely rolled up, and reduce the speed of the reel to prevent overstretching of the covering film.

[0089] 6. In step seven, the tape application length can be controlled by setting the reel to roll up a specific distance.

[0090] 7. In step eight, the process of the carrier tape end entering the reel hole can be achieved by setting a positioning guide device or a sensing centering mechanism to achieve accurate alignment.

[0091] Example 2:

[0092] This embodiment further improves the carrier tape transmission system based on Embodiment 1.

[0093] To achieve precise positioning control of the carrier belt, the carrier belt guiding device was replaced with a precision linear guide rail. This guide rail is combined with a high-precision linear motor, and closed-loop control of the carrier belt's position is achieved through closed-loop control. The motor's position feedback uses a high-precision optical encoder.

[0094] The carrier tape feeding device and the winding device are also driven by servo motors and equipped with a driven encoder to achieve dual closed-loop control of speed and position. A force sensor is installed at each end of the winding device to detect the winding tension in real time and feed it back to the motor to complete the tension closed-loop control.

[0095] The carrier tape heat sealing mechanism has been replaced with a precision CNC cylinder as the actuating body, which, together with the guide rail, completes the precise positioning of the carrier tape during the sealing process. The heat sealing head uses a PID temperature control system for temperature control.

[0096] By adopting closed-loop servo control throughout the motion system, accurate planning and control of speed, position, and tension during carrier tape transport can be achieved, ensuring smooth carrier tape movement and improving packaging quality.

[0097] Example 3:

[0098] This embodiment is based on Embodiment 1, and the cutting mechanism has been optimized and improved.

[0099] High-speed, precise cutting is achieved using a high-speed flying cut method.

[0100] 1) The cutting execution base is a set of high-speed flying cutters, including ring blades mounted on a high-speed rotating spindle.

[0101] 2) The cutting tissue is combined with a linear slide driven by a servo motor, and the flying cutter can perform high-speed flying shearing in the width direction of the carrier tape.

[0102] 3) The slide movement trajectory and speed curve are planned by the control system and closed-loop control is achieved by combining encoder feedback.

[0103] Two independent flying cut systems are set up to cut the carrier tape simultaneously. The two systems are staggered, with the first system completing the pre-cut and the second system precisely cutting the carrier tape.

[0104] In addition, a laser alignment system is set up at the cutting position to detect the movement of the carrier belt and feed the signal back to the controller in the flying cut system to correct the cutting timing of the flying cutter in real time, thereby achieving high-precision cutting length control.

[0105] Employing a flying cutter method, coupled with two sets of cutting systems, it can achieve high-speed, precise, chip-free cutting, greatly improving the efficiency of automated roll changing and making it suitable for high-speed continuous production.
