Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a tape turning and changing mechanism. Background Technology

[0002] In the field of automated production of electronic components, tape and reel packaging is a core process for the packaging and transportation of tiny devices such as semiconductor chips and passive components. The tape and reel system uses a composite structure of carrier tape and cover tape to sequentially fix components in the grooves of the carrier tape, and then completes the packaging through heat sealing or adhesive bonding. Finally, the components are wound onto a reel for subsequent surface mount technology (SMT) processes.

[0003] Between the Marking process and the FT process, some products require adjustments to the tape reel direction (e.g., from horizontal to vertical or reverse winding) to adapt to different test fixtures or packaging specifications, depending on the testing equipment or customer requirements. Traditional methods rely on manual unwinding and rewinding, which is not only inefficient but also prone to component misalignment, contamination, or electrostatic discharge (ESD) damage due to operational errors.

[0004] Automated winding equipment shortens production cycles by increasing speed, but high-speed friction can cause the static electricity on the carrier tape surface to spike (up to several kilovolts), potentially leading to dust adsorption on components, short circuits at leads, or damage to microstructures. Existing technologies mostly reduce static electricity by using external ion fans or grounding devices, but the effect is limited and cannot dynamically adapt to changes in speed.

[0005] Therefore, this application develops a tape flipping and rewinding mechanism to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a tape flipping and reel changing mechanism to solve the problems of inconvenience in flipping products and changing reels in the prior art.

[0007] The technical solution of this utility model is: a tape flipping and rewinding mechanism, comprising:

[0008] Support frame;

[0009] Both the feeding device and the receiving device are mounted on the supporting frame and are configured to rotate around their own central axis. The feeding device is used to carry and release the carrier belt carrying the product and the protective belt covering it. The receiving device is used to recycle the protective belt and the carrier belt.

[0010] A buffer section is provided on the supporting frame and located between the feeding device and the receiving device;

[0011] The protective belt is led out from the feeding device, passes through the buffer section, and is then connected to the receiving device. The carrier belt and the protective belt are transported in different directions between the feeding device and the receiving device, so that the product is flipped during the transport process.

[0012] Preferably, a correction device is installed on the support frame, and both the receiving device and the discharging device are equipped with at least one correction device. Each correction device has a pair of grooves, and the edges of the receiving device and the discharging device are inserted into the corresponding grooves to limit the deformation of the receiving device and the discharging device.

[0013] Preferably, the buffer section includes multiple fixed wheels and multiple movable wheels, and the protective belt alternately wraps around the fixed wheels and the movable wheels in an S-shaped path.

[0014] Preferably, the inner wall of the supporting frame is provided with a sliding device, the sliding device including a guide rail and a mounting seat that slides along the guide rail, the movable wheel is mounted on the mounting seat and slides along the guide rail with the mounting seat to move closer to or away from the fixed wheel.

[0015] Preferably, the support frame has a detection area located below the feeding device and the receiving device, and multiple detection devices are arrayed in the detection area along the extension direction of the guide rail for detecting the descent height of the carrier belt.

[0016] Preferably, a micro switch is provided at the top of the detection area, and the height of the micro switch is higher than the installation height of the detection device, in order to prevent the carrier belt from becoming taut.

[0017] Preferably, the carrier belt and the protective belt are respectively equipped with ion guns at the receiving position and the discharging position, and the air outlet of the ion guns faces the corresponding receiving position and the discharging position to eliminate static electricity in the area.

[0018] Preferably, both the feeding device and the receiving device are equipped with laser sensors on one side along the radial direction to monitor the thickness of the corresponding tape and thus monitor the amount of remaining material.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] (1) When the receiving device and the discharging device rotate in the same direction, the discharging device that has completed its work can be replaced at any time without stopping the equipment. This feature greatly reduces production downtime, improves production efficiency, and avoids the disruption to the production rhythm caused by frequent equipment start-ups and shutdowns;

[0021] (2) The buffer section, through the design of fixed wheels and movable wheels, and in conjunction with the sliding device, can flexibly adjust the position of the movable wheel according to the actual tension of the protective belt, so as to achieve precise control and buffering of the tension of the protective belt. The protective belt is wrapped alternately between the fixed wheel and the movable wheel in an S-shape. Initially, the mounting seat is located at the top of the guide rail. When the length of the protective belt increases, the mounting seat slides down to ensure that the protective belt is tight and to ensure stable transmission of the protective belt, so as to avoid affecting the product quality due to tension problems.

[0022] (3) A correction device is set along the diameter direction at the edge of the receiving device and the discharging device. Its groove is adapted to the edge of the device. When installed, the edge of the device is inserted into the groove to form a stable constraint. When in operation, the correction device can resist different forces, limit the deformation range of the device, and ensure the continuous, stable and efficient operation of the equipment.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to specific embodiments:

[0031] like Figures 1-3As shown, a tape-and-reel changing mechanism includes a support frame 1, a feeding device 2, a receiving device 3, and a buffer section 4. The support frame 1 serves as the main support, providing a foundation for the installation and fixation of other components, ensuring the overall stability of the mechanism. The feeding device 2 and the receiving device 3 are both mounted on the support frame 1, and each has a motor mounted on its central axis, causing both to rotate around their respective central axes. The feeding device 2 primarily carries the carrier tape containing the product and the protective tape covering it, releasing them during operation. The receiving device 3 is responsible for collecting the used protective tape and carrier tape. The buffer section 4 is located on the support frame 1, positioned between the feeding device 2 and the receiving device 3, buffering and adjusting the tension of the protective tape during transmission. During operation, the protective tape, after being drawn from the feeding device 2, passes through the buffer section 4 and then connects to the receiving device 3.

[0032] In this embodiment, as Figure 1 As shown, a sliding device 6 is installed on the inner wall of the supporting frame 1. The sliding device 6 includes a guide rail 61 and a mounting base 62. The guide rail 61 is fixed to the inner wall of the supporting frame 1, and the mounting base 62 matches the guide rail 61, allowing it to slide smoothly on the guide rail 61. The buffer part 4 includes multiple fixed wheels 41 and multiple movable wheels 42. The multiple fixed wheels 41 are fixed to the supporting frame 1 and located above the feeding device 2 and the receiving device 3. The movable wheels 42 are fixed to the mounting base 62, ensuring that the movable wheels 42 will not loosen or shift during the sliding process of the mounting base 62. In practical applications, the protective belt is connected to the receiving device 3 from above the feeding device 2 and around the buffer part 4, while the carrier belt is connected to the receiving device 3 from below the feeding device 2. Initially, the material diameter in the feeding device 2 is large, while the material diameter in the receiving device 3 is small. Therefore, in During material transport, the speeds of the two devices are inconsistent, and the protective belt and carrier belt must remain taut. If the speed of the receiving device 3 is too fast, the material may stretch, deform, or even break. If the speed of the receiving device 3 is too slow, the material may become wrinkled or tangled. Therefore, the speed of the receiving device 3 can be adjusted to be slightly slower than that of the discharging device 2. The protective belt is wound alternately in an S-shape between the fixed wheel 41 and the movable wheel 42. Initially, the mounting base 62 is located at the top of the guide rail 61. As the length of the protective belt increases, the mounting base 62 slides downward under the action of gravity, thus ensuring the tautness of the protective belt. This design allows for flexible adjustment of the position of the movable wheel 42 according to the actual tension of the protective belt during transmission, achieving precise control and buffering of the protective belt tension. This ensures that the protective belt maintains a stable transmission state during the tape turning and rewinding process, improving the overall performance and reliability of the mechanism.

[0033] In another embodiment, such as Figures 4-5As shown, the buffer section 4 is additionally equipped with a drive device 43 and a sliding plate 44. The sliding plate 44 is connected to the drive end of the drive device 43, and under the drive of the drive device 43, the sliding plate 44 can slide along the guide rail 61. Simultaneously, some fixed wheels 41 are mounted on the sliding plate 44. When the sliding plate 44 slides along the guide rail 61, these fixed wheels 41 move together with the sliding plate 44, thereby extending the operating path range of the protective belt and more effectively ensuring that the protective belt maintains appropriate tension.

[0034] To further explain, when the rotation directions of the receiving device 3 and the discharging device 2 are the same, the discharging device 2, which has completed its work, can be replaced at any time, and the equipment can be kept running without stopping. When the rotation directions of the receiving device 3 and the discharging device 2 are opposite, the material is turned over to meet the needs of the next process.

[0035] To prevent the take-up device 3 and the unloading device 2 from deforming during operation and affecting the feeding and take-up processes, two correction devices 5 are respectively installed along the diameter direction on the edges of the take-up device 3 and the unloading device 2. Each correction device 5 has a pair of grooves 51, and the shape and size of the grooves 51 are adapted to the edges of the take-up device 3 and the unloading device 2. During installation, the edges of the take-up device 3 and the unloading device 2 are inserted into the grooves 51 of the corresponding correction devices 5, thus forming a stable constraint relationship. When the take-up device 3 and the unloading device 2 start operating to perform the take-up and unloading operations of the carrier tape and the protective tape, the correction devices 5, by virtue of the locking and limiting of the edges of the take-up device 3 and the unloading device 2 by their grooves 51, can effectively resist the influence of different forces, strictly limit the deformation range of the take-up device 3 and the unloading device 2, thereby ensuring that the entire tape turning and changing mechanism can operate continuously, stably, and efficiently.

[0036] In this embodiment, as Figure 2 As shown, the supporting frame 1 has a detection area 11, which is spatially positioned directly below the feeding device 2 and the receiving device 3. Inside the detection area 11, multiple detection devices 7 are arranged in an array along the extension direction of the guide rail 61. Each detection device 7 has a transmitting part 71 and a receiving part 72 arranged opposite to each other. When the carrier belt moves between the transmitting part 71 and the receiving part 72, the height of the carrier belt can be detected. In actual operation, the arrayed detection devices 7 capture the height information of the carrier belt at different positions in real time and quickly transmit this data to the control system. The control system analyzes and processes this data to accurately calculate the descent height of the carrier belt, and then adjusts the operating status of the winding machine according to preset parameters, such as controlling the feeding speed and adjusting the tension, to ensure that the carrier belt remains stable throughout the transmission process, thereby improving the working accuracy of the winding machine and the product quality.

[0037] Furthermore, in the overall structure of the winding machine, static electricity is easily generated during the take-up and unload processes of the carrier tape and protective tape, which can affect production quality. Therefore, ion guns 9 are correspondingly configured at the take-up and unload positions of the carrier tape and protective tape, with the air outlets of the ion guns 9 facing the corresponding take-up and unload positions. When these ions are blown out of the air outlets with the airflow and act on the take-up and unload areas, they neutralize the static electricity generated on the surface of the carrier tape and protective tape in that area due to friction and other reasons. This quickly and effectively eliminates static electricity at the take-up and unload positions, avoiding problems such as static electricity attracting dust, causing the carrier tape and protective tape to stick together, or affecting the positioning accuracy of electronic components on the carrier tape. This ensures the stable operation of the winding machine during the take-up and unload processes and improves the production quality and reliability of the products.

[0038] Furthermore, laser sensors 10 are installed on one side of the receiving device 3 and the discharging device 2 along the radial direction. When the laser beam irradiates the tape, it generates corresponding reflection signals according to the different thicknesses of the tape, thereby accurately measuring the thickness of the tape. By continuously monitoring the changes in the thickness of the tape at the discharging device 2 and the receiving device 3, the system can monitor the amount of remaining material in the tape in real time. In practical applications, during the discharging process, the thickness of the tape at the discharging device 2 gradually decreases as the tape is continuously released; while during the receiving process, the thickness of the tape at the receiving device 3 gradually increases. When the amount of remaining material is lower than the preset safety threshold, the system will promptly issue an alarm signal to remind the operator to replace the tape or perform other corresponding operations in time to ensure the continuous and stable operation of the winding machine and avoid production interruptions and quality problems caused by material shortages. In addition, a micro switch 8 is installed at the top of the detection area 11, and the height of the micro switch 8 is higher than the installation height of the detection device 7. This prevents the receiving device 3 from moving too fast when the detection device 7 malfunctions, causing the carrier tape to detach from the detection area 11, resulting in the carrier tape becoming taut and subsequently deformed or broken.
