Description

Technical Field

[0001] This utility model belongs to the field of tape and cord packaging machines and relates to a product feeding device inside tape and cord. Background Technology

[0002] In industries such as electronics manufacturing, tape and reel packaging is a common method for packaging components, and the components placed inside the tape and reel are usually small in size.

[0003] After the feeder stage, existing tape packaging machines require transferring components into the tape. Currently, this is mainly done using suction nozzles to pick up the product. However, during the nozzle's vertical movement, various factors, such as mechanical vibration, airflow interference, and nozzle precision errors, can cause positional deviations when the nozzle picks up the product. These deviations directly lead to unstable product feeding when placed on the tape, potentially causing components to become misaligned, tilted, or even fall off within the tape. Utility Model Content

[0004] The purpose of this utility model is to provide a product feeding device inside the tape and reel, which improves the stability of products when they are fed into the tape and reel at high speed through structural improvements.

The suction nozzle assembly includes a suction nozzle, an air passage communicating with the suction nozzle, and a pneumatic control element for controlling the opening and closing of the air passage. The suction nozzle assembly can pick up the product from the feeder outlet and transfer the product to the calibration mechanism.

[0008] The calibration mechanism uses a center alignment method to calibrate the product's position. The calibration mechanism includes a calibration platform for supporting the product and multiple radially movable calibration components arranged around the calibration platform. The calibration components move synchronously to make the product's center coincide with the preset center position of the calibration platform.

The CCD camera is used to sense the product position on the suction nozzle, and the rotary motor adjusts its angle according to the product position information obtained by the CCD camera.

[0015] As a further improvement of one embodiment of this utility model, an optical path amplifier is also provided, wherein the CCD camera receives the product image magnified by the optical path amplifier, and the turntable drives the suction nozzle to pass through the optical path amplifier.

[0016] As a further improvement of one embodiment of the present invention, the track frame is provided with a sensor to monitor whether there is a product on the suction nozzle before it enters the feeding station.

Example

[0042] See Figures 1-4 As shown, a product feeding device for tape and reel is mainly used to accurately and stably place small components and other products inside the tape and reel to meet the automated production needs of industries such as electronics manufacturing.

[0043] The feeding device includes a machine base 1, which provides a stable support foundation for the entire device. On the machine base 1, feeders 2, turntables 4, calibration mechanisms 7 and track frames 3 for placing tapes are reasonably arranged and installed.

[0044] The track frame 3 is used to support the tape, and a needle wheel drive mechanism is provided on one side of it. The needle wheel drive mechanism drives the drive needle wheel 5 to rotate through the drive motor 9. The drive needle wheel 5 cooperates with the holes on the tape, thereby driving the tape to move stably on the track frame 3 along a set direction.

[0045] The turntable 4 is driven by a high-powered motor, which provides sufficient power to enable the turntable 4 to rotate at high speed and stably around its own axis. At least one suction nozzle assembly 8 is mounted on the turntable 4. The suction nozzle assembly 8 includes a suction nozzle 83, an air passage connected to the suction nozzle 83, and a pneumatic control element 82 that controls the opening and closing of the air passage. When material needs to be picked up, the pneumatic control element 82 controls the air passage to open, creating negative pressure in the suction nozzle 83, thereby allowing the product to be adsorbed from the feeder 2 outlet. When material needs to be discharged, the pneumatic control element 82 controls the air passage to close, the suction nozzle 83 loses negative pressure, and the product detaches from the suction nozzle 83. The suction nozzle assembly 8 can accurately adsorb the product from the feeder 2 outlet and transfer it to the calibration mechanism 7.

[0046] The calibration mechanism 7 uses a center alignment method to perform position calibration on the product. The calibration mechanism 7 includes a calibration platform for carrying the product and multiple radially movable calibration elements 72 arranged around the calibration platform. The calibration elements 72 move synchronously and push the product from different directions so that the center of the product coincides with the preset center position of the calibration platform, thereby completing the position calibration of the product.

[0047] The track frame 3 is equipped with a feeding station. After being calibrated by the calibration mechanism 7, the product is again adsorbed by the suction nozzle assembly 8. Subsequently, the suction nozzle assembly 8 moves with the turntable 4 to the feeding station, accurately placing the product in the corresponding position within the tape, ensuring the stability of the product when it is placed into the tape during high-speed operation.

[0048] In this embodiment, the needle wheel drive mechanism specifically includes a drive motor 9, a transmission shaft, and a drive needle wheel 5. The drive motor 9 serves as a power source, with its output shaft connected to the transmission shaft, driving the transmission shaft to rotate. The drive needle wheel 5 is fixed to the transmission shaft and rotates synchronously with it. The drive needle wheel 5 has needle teeth whose size and spacing match the holes on the tape, allowing for precise insertion into the holes. When the drive motor 9 starts, it drives the drive needle wheel 5 to rotate, and the engagement of the needle teeth with the holes drives the tape to move stably along the direction defined by the track frame 3.

[0049] On the other side of the track frame 3, a needle wheel mounting bracket is provided, on which a guide needle wheel 6 is mounted via a pivot. The guide needle wheel 6 corresponds to the position of the drive needle wheel 5, and its needle teeth can also be inserted into the holes of the tape. The guide needle wheel 6 and the drive needle wheel 5 work together to guide and drive the tape from both sides, ensuring the smooth movement of the tape.

[0050] In addition, auxiliary wheels 11 are provided on the outer sides of both the driving needle wheel 5 and the guide needle wheel 6. The auxiliary wheels 11 can be in the form of bearings or other structures. Their function is to provide auxiliary support and guidance for the tape, prevent the tape from shifting or shaking during movement, and further improve the accuracy and stability of the tape movement.

[0051] In this embodiment, the calibration mechanism 7 includes a four-jaw cylinder 71. A calibration platform is located at the center of the four-jaw cylinder 71. The surface of the calibration platform is flat and smooth, providing a stable foundation for product placement. Calibration components 72 are mounted on the wedge-shaped blocks of the four-jaw cylinder 71. One end of each calibration component 72 is raised to form a pushing part, which is located on the calibration platform. When the four-jaw cylinder 71 is activated, its wedge-shaped blocks drive the calibration components 72 to move synchronously. The four pushing parts can then close together to form a contour groove for product placement. The shape and size of this contour groove are adapted to the shape of the product to be calibrated, enabling precise product positioning.

[0052] Preferably, the calibration mechanism 7 also includes a rotary motor 74, which is mounted on the calibration bracket 73 and connected to a four-jaw cylinder 71. The rotary motor 74 drives the four-jaw cylinder 71 to rotate, thereby adjusting the angle of the product on the calibration platform. Furthermore, a CCD camera 75 is positioned outside the four-jaw cylinder 71. As the nozzle moves with the turntable, it first passes the CCD camera 75 before reaching the four-jaw cylinder 71. The CCD camera 75 senses the position of the product on the nozzle and transmits the acquired product position information to the control system. Based on this information, the control system controls the rotary motor 74 to make corresponding angle adjustments, ensuring the product is placed at the correct angle on the calibration platform. This ensures the accurate positioning of products subsequently placed in the tape tray, improving the precision and stability of the entire feeding device.

[0053] In this embodiment, an optical path amplification auxiliary structure is adopted to improve the accuracy of product position information acquired by the CCD camera 75. Specifically, the CCD camera 75 does not directly photograph the product on the nozzle. An optical path amplifier is added to the machine base 1. This optical path amplifier can achieve optical path amplification through common equivalent structures such as optical lens groups. When the product on the nozzle passes through the optical path amplifier, the optical path amplifier magnifies the product image. Subsequently, the CCD camera 75 receives the magnified product image. The product position information obtained after image processing is more accurate, which helps to improve the calibration effect of the calibration mechanism 7.

[0054] In this embodiment, a sensor 10 is installed on the track frame 3. Its function is to monitor whether the suction nozzle carries a product before entering the unloading station. The sensor 10 can adopt a common equivalent structure such as a photoelectric sensor, and determines the presence or absence of a product by detecting changes in the environment around the suction nozzle, thus ensuring the accurate execution of the unloading process.

[0055] In this embodiment, a plurality of nozzle mounting plates 81 are evenly arranged circumferentially along the edge of the turntable 4. These nozzle mounting plates 81 can be fixed to the turntable 4 by common mechanical connection methods such as welding and bolting, providing a mounting base for the pneumatic control components 82 and the nozzles 83.

[0056] Each nozzle mounting plate 81 is equipped with a pneumatic control element 82, which in this embodiment is specifically a solenoid valve. The solenoid valve can precisely control the opening and closing of the air path. It has a compact structure and fast response speed, and can effectively meet the control requirements of the nozzle 83 for product adsorption and release.

[0057] Each pneumatic control element 82 is equipped with a suction nozzle 83, which is used to directly contact and adsorb the product. A main air duct 84 is located at the center of the turntable 4, and several quick-connect fittings 85 are installed on the side wall of the main air duct 84, connecting to it. Each quick-connect fitting 85 corresponds to a pneumatic control element 82, and the two are connected by a flexible hose. This connection method facilitates installation and maintenance while ensuring the stability of the air circuit connection.

[0058] The product feeding device inside the tape and cord provided by this utility model is a component of the tape and cord packaging machine. It is closely integrated with other parts of the tape and cord packaging machine and shares the control system, power supply system, air supply system, vacuum system, etc. of the tape and cord packaging machine. Through a unified interface and operation instructions, it realizes the coordinated operation of each link and achieves automated production.

[0059] The product loading device for tape and reel provided by this utility model uses a turntable 4 as a transmission carrier, leveraging its stable rotational characteristics to drive the suction nozzle assembly to transfer products. During the transfer process, when the product is transported to the calibration mechanism by the suction nozzle assembly, the calibration mechanism uses multi-directional calibration components to move synchronously, precisely adjusting and correcting the product position. In addition to the aforementioned physical calibration, CCD camera recognition and angle adjustment via a rotary motor can also be added, offering greater flexibility. After calibration, the product is placed into the tape and reel in an accurate posture, effectively avoiding positional deviations. Even at high speeds, the stability of product placement into the tape and reel is ensured, greatly improving overall production efficiency and product quality.
