[0002] In the field of electronic component manufacturing, tape and reel packaging inspection is a crucial step in ensuring product quality and achieving efficient production. As electronic products evolve towards miniaturization and high performance, higher demands are placed on the accuracy, efficiency, and automation of electronic component tape and reel packaging inspection. Tape and reel packaging inspection lines are integrated automated production lines that combine component tape and reel packaging, appearance inspection, and performance testing, and are widely used in the mass production of surface mount technology (SMT) components.

[0014] Preferably, in any of the above embodiments, the upper wide-angle camera is located on one side of the alternating shuttle platform. The upper wide-angle camera, lower camera, gantry robot, and suction head are all signal-connected to the PLC control unit. The gantry robot consists of a fixed supporting bracket, a motor-driven X-axis guide rail, and a Y-axis guide rail. The supporting bracket is fixedly installed inside the tape tray frame. The top of the supporting bracket is fixedly installed with the motor-driven Y-axis guide rail, and the top of the Y-axis guide rail is fixedly installed with the X-axis guide rail.

The system features a panel light source (LED) and five linear array custom suction nozzles. The high resolution and wide-angle lens of the upper wide-angle camera cover the entire area of ​​the alternating shuttle platform, ensuring rapid material positioning. The disordered positioning function adapts to randomly placed materials. The ring light source of the lower camera eliminates surface reflections on the materials.

[0016] Preferably, in any of the above embodiments, the heat-sealing packaging assembly includes a heat-sealing bracket fixedly installed inside the tape-making machine frame.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figure 1-5As shown in the figure, a novel tape and reel packaging testing line according to an embodiment of the present invention includes a board collecting machine 1 for collecting and organizing products and a tape and reel packaging machine 2 for packaging products. The board collecting machine 1 includes a board collecting frame 11 for support. One end of the board collecting frame 11 is fixedly installed with a jig and a PCB feeding track 12. A four-axis robot 13 for gripping products is set on one side of the feeding track 12. An empty jig discharge track 14 for outputting empty jigs into a material frame is set on one side of the four-axis robot 13. A jig and material frame lifting mechanism 15 for lifting and lowering the material frame is set on one side of the empty jig discharge track 14. The tape and reel packaging machine 2 includes an alternating shuttle platform 21 for conveying materials. A tape and reel packaging frame 22 for support and fixation is fixedly installed at the bottom of the alternating shuttle platform 21. A wide-angle camera 23 for disordered positioning of materials is fixedly installed at the top of the 22. The wide-angle camera 23 is connected to a PLC control unit for automated control. The PLC control unit is connected to a lower camera 24 for contour detection and secondary positioning of materials. A gantry robot 25 for moving materials is set between the wide-angle camera 23 and the lower camera 24. A suction head 28 for gripping materials is fixedly installed at the bottom of the gantry robot 25. A heat-sealing packaging component 26 for tape and reel packaging of materials is set on one side of the gantry robot 25. A tray 27 for collecting defective products is set on one side of the heat-sealing packaging component 26. An alternating shuttle platform 21 is fixedly installed inside the receiving frame 11 and is located on the same straight line as the feeding track 12.

[0023] Preferably, in any of the above schemes, the inside of the plate receiving frame 11 is fixedly installed with a touch screen, operation buttons and power switch connected to the PLC control unit signal, and the middle of the plate receiving frame 11 is fixedly installed with a drive box that provides power to the feeding track 12, the drive box and the PLC control unit signal, and the inside of the feeding track 12 is provided with a conveyor belt assembly fixedly installed at the output end of the drive box.

[0024] The above technical solution is adopted as follows: The receiving frame 11 (constructed of high-strength aluminum alloy profiles with anodized surface) has a 10-inch touch screen (connected to the PLC control unit via RS485 bus), three self-reset operation buttons (emergency stop, start, pause), and a boat-shaped power switch fixedly installed inside. The drive box (with built-in servo driver) is fixedly installed in the middle to provide power to the feeding track 12. The feeding track 12 (aluminum alloy material) has a conveyor belt assembly (polyurethane material with anti-slip texture on the surface) inside, which is driven by the output end of the drive box through a synchronous pulley. The aluminum alloy frame is lightweight and rigid, and can withstand the vibration of the equipment without deformation. The touch screen supports parameter settings (such as conveying speed, barcode scanning mode) and production data display (such as output, NG rate). The operation buttons realize emergency stop and process control. The power switch has overload protection. The servo driver of the drive box can accurately adjust the speed of the conveyor belt to adapt to the conveying needs of different specifications of fixtures. The polyurethane belt is wear-resistant, and the anti-slip texture ensures that the fixture is conveyed without slippage, while also buffering the impact of the fixture.

[0025] The touchscreen operates on the principle of capacitive sensing. When the operator touches the screen, the screen converts the position signal into an electrical signal, which is transmitted to the PLC control unit. The PLC processes the signal and outputs instructions to control components such as the drive box and the four-axis robot 13. The servo driver in the drive box receives pulse signals from the PLC and controls the motor speed, which drives the conveyor belt through the synchronous pulley to achieve linear transport of the fixture and PCB. The operation buttons are connected to the PLC input terminals through normally open or normally closed contacts. When the emergency stop button is triggered, it directly cuts off the drive power to ensure emergency shutdown of the equipment. When the power switch is turned on, the equipment performs a power-on self-test, and the touchscreen displays the "standby" interface. The operator sets the conveyor speed through the touchscreen and presses the "start" button. The PLC controls the drive box to start, and the servo... The motor drives the conveyor belt assembly to place the fixture containing the PCB at the inlet of the feed track 12. The belt then transports the fixture towards the four-axis robot 13. During the transport process, the touch screen displays the transport speed and fixture position in real time. If a pause is required, press the "Pause" button to stop the belt. In case of an abnormality, press the "Emergency Stop" button to immediately cut off the power to the equipment. The device can only be restarted after the fault is cleared and the reset button is pressed. The PLC control unit uses a PID algorithm to adjust the output pulse frequency of the drive box based on the speed value set on the touch screen and the actual speed of the belt (detected by an encoder). The touch screen accuracy is calibrated periodically, and the screen surface is cleaned. The tension of the conveyor belt is detected by a tension meter. If the tension is insufficient, the belt tensioning pulley is adjusted; if the tension exceeds the limit, the belt is replaced.

[0026] Preferably, in any of the above solutions, the four-axis robot 13 is fixedly installed inside the receiving frame 11. The output end of the four-axis robot 13 is fixedly installed with a connecting plate for support. One end of the connecting plate is fixedly installed with a vacuum suction cup assembly for gripping materials, and the other end of the connecting plate is fixedly installed with an industrial barcode scanner for assembling and scanning materials. The four-axis robot 13 and the PLC control unit signal are also fixedly installed.

[0027] The above technical solution is adopted: a four-axis robot 13 (model SCARA-RH6, connected to the PLC control unit via EtherCAT bus) is fixed inside the board receiving frame 11. The output end is bolted to a connecting plate (aerospace aluminum alloy material). A vacuum suction cup assembly (4 polyurethane suction heads, equipped with an integrated vacuum detection sensor) is installed on one end of the connecting plate, and an industrial barcode scanner (using an industrial camera, capable of positioning MARK and scanning QR codes and barcodes for easy uploading to EMS, supporting DM and QR code recognition, and connected to the PLC signal) is installed on the other end. The high positioning accuracy of the four-axis robot ensures accurate jig gripping and placement, adapting to the needs of precision PCB operation. The vacuum suction cup assembly uses negative pressure to adsorb the jig, ensuring stable gripping. The vacuum detection sensor monitors the vacuum level in real time, forming a feedback system with the PLC. The industrial barcode scanner can quickly identify PCB panel codes and upload the data to the EMS system to achieve product traceability. The lightweight design of the connecting plate reduces the robot load, and the aerospace aluminum alloy material is corrosion resistant.

[0028] The four-axis robot is driven by servo motors. A PLC control unit sends pulse signals to control the rotation of each axis motor. A reducer increases torque, enabling precise positioning of the end-effector plate. A vacuum suction cup assembly generates negative pressure via a vacuum pump, creating a sealed cavity between the suction cup and the fixture surface. Atmospheric pressure is used for adsorption. A belt conveyor feeds the fixture and product into the machine. Once the product is in place, the robot arm scans the barcode. The robot arm then picks up the fixture and product, placing the fixture onto an alternating shuttle platform. The robot arm lifts the platform, simultaneously separating waste boards and discarding them into a waste bin. The alternating shuttle platform carries the fixture and product into the tape-making machine while another platform returns with an empty fixture. The robot arm retrieves the empty fixture and places it into a fixture with a product, repeating the cycle. An industrial barcode scanner uses a CMOS image sensor to capture barcode images. After decoding using a built-in algorithm, the barcode data is transmitted to the PLC via an RS232 bus. The PLC then uploads the data to the EMS system. The material track 12 transports the fixture to the working area of ​​the four-axis robot 13. The PLC controls the robot to move above the fixture. The vacuum suction cup assembly is powered on, the vacuum pump starts to generate negative pressure, the suction cups adsorb the fixture, and the vacuum detection sensor confirms that the vacuum level meets the standard. The robot moves the fixture, the industrial barcode scanner aligns with the PCB panel code, completes the scanning and uploads the data. After scanning, the robot places the fixture on the alternating shuttle platform 21, the vacuum suction cups depressurize, and the fixture is released. Then the robot grabs the empty fixture and transports it to the fixture material frame lifting mechanism 15 through the empty fixture discharge track 14. The PLC control unit generates the robot's motion trajectory (such as a straight line or arc) through the motion control module to ensure coordinated movement of each axis. The signal from the vacuum detection sensor is connected to the PLC input terminal. When the vacuum level does not meet the standard, an alarm is triggered (the touch screen displays "Suction Cup Abnormal"). The decoding success rate of the industrial barcode scanner is statistically analyzed by the PLC.

[0029] Preferably, in any of the above schemes, the empty fixture discharge track 14 is fixedly installed at one end of the plate collecting machine 1, the top of the empty fixture discharge track 14 is provided with a sliding seat for placing the empty fixture, the fixture material frame lifting mechanism 15 is fixedly installed inside the plate collecting machine frame 11, and one end of the fixture material frame lifting mechanism 15 is fixedly installed with the alternating shuttle platform 21.

[0030] The above technical solution is adopted as follows: the empty jig discharge track 14 (aluminum alloy material, parallel to the feed track 12) is fixed to one end of the plate take-up machine 1, and a sliding seat (ABS plastic material with PTFE wear-resistant layer on the surface) is provided at the top, which can slide along the track. The jig material frame lifting mechanism 15 (including servo motor, ball screw and lifting platform) is fixed inside the plate take-up machine frame 11. One end of the lifting platform is bolted to the alternating shuttle platform 21, which can realize lifting. The PTFE wear-resistant layer of the sliding seat reduces friction with the track and ensures smooth delivery of the empty jig. The ABS material is lightweight and impact-resistant. The jig material frame lifting mechanism 15 can lift the empty material frame or lower the full material frame to adapt to the needs of AGV material picking or manual material picking. The lifting platform is connected to the alternating shuttle platform 21 and can adjust the height synchronously to ensure that the empty jig smoothly transitions from the discharge track to the material frame. The coordinated design of the track and the lifting mechanism realizes the automated recycling of the empty jig and reduces manual intervention.

[0031] The empty fixture discharge track 14 is based on the principle of combining gravity and thrust. The four-axis robot 13 places the empty fixture on the sliding seat. Under the action of gravity and robot thrust, the sliding seat slides along the track until it reaches the lifting platform. The fixture material frame lifting mechanism 15 is based on the principle of screw drive. The servo motor drives the ball screw to rotate, converting the rotational motion into the linear motion of the lifting platform, realizing the lifting of the material frame. The position of the lifting platform is detected in real time by an encoder. The PLC control unit adjusts the lifting height according to the material frame overflow signal (detected by a photoelectric sensor). The four-axis robot 13... After grabbing an empty jig, it is moved above the empty jig discharge track 14 and placed on the sliding seat. The sliding seat slides along the track to the lifting platform of the jig material frame lifting mechanism 15. The PLC controls the lifting mechanism to start, and the servo motor drives the ball screw to rotate. The lifting platform descends to the height of the material frame, and the sliding seat pushes the empty jig into the material frame. When the number of empty jigs in the material frame reaches the set value, the photoelectric sensor detects that it is full. The PLC controls the lifting platform to descend to the ground, and the AGV or manual removal of the full material frame is performed. Then the lifting platform rises to receive a new empty material frame, and the recycling process is repeated. Control principle and method: The PLC control unit controls the speed of the servo motor of the lifting mechanism through pulse signals. The number of motor rotation steps is calculated according to the target height of the lifting platform. The sliding position of the sliding seat is detected by the photoelectric sensor. An alarm is triggered when there is jamming. The ball screw is lubricated regularly (by applying lithium-based grease).

[0032] Preferably, in any of the above solutions, the tape tray frame 22 is attached to one end of the take-up frame 11, and an operation panel for opening and closing is fixedly installed at one end of the tape tray frame 22, which is connected to the PLC control unit signal and an operation support plate for opening and closing. A printer that is fixedly installed with the heat-sealing packaging assembly 26 is fixedly installed at the bottom of one end of the tape tray frame 22.

[0033] The above technical solution is adopted: the tape tray frame 22 (built with high-strength aluminum alloy profiles, anodized surface) is attached to one end of the take-up frame 11. One end is fixed with a 12-inch operation screen (capacitive touch, connected to the PLC control unit via Ethernet) and an openable operation support plate (ABS plastic material). A label printer (thermal type, supports QR code printing, connected to the PLC signal) is fixed at the bottom. The printer's paper output is aligned with the full-load tape take-up roller of the heat-sealing packaging component 26. Detailed functions: The aluminum alloy frame and take-up frame are designed to fit together, reducing the line's footprint while ensuring that the alternating shuttle platform 21 and the feeding track 12 are coaxial. The operation screen supports visual parameter settings (such as camera exposure time and detection threshold) and packaging process monitoring (such as heat-sealing temperature and take-up speed). The operation support plate can hold tools (such as suction nozzles and cleaning cloths) or temporary materials. The openable structure facilitates internal equipment maintenance. The thermal printer can automatically print labels (including product model, production date, and QR code) when the tape is full. After the label is attached to the tape, product traceability is achieved. The printing speed is adapted to the line's production capacity.

[0034] The operation panel, based on Ethernet communication, interacts with the PLC control unit in real time. Operator-set instructions such as heat-sealing temperature and camera parameters are transmitted to the PLC via the network. The PLC then controls the heat-sealing packaging component 26 and the gantry robot 25 to execute these commands. The operation support plate is connected to the frame via hinges and secured with clips when closed. After receiving the printing command from the PLC, the printer's thermal print head heats up and prints the data onto the thermal paper. The paper cutter automatically cuts the labels. After the tape machine 2 starts, the operation panel displays the "Tape Standby" interface. The operator sets the heat-sealing temperature and detection threshold through the operation panel, lowers the operation support plate, and places maintenance tools. After the heat-sealing packaging component 26 completes the sealing of one roll of tape, the PLC sends a printing command. The printer starts, the thermal printhead heats and prints the label. After the label is cut, it falls onto the operating support plate. The operator removes the label and attaches it to the full-load take-up reel. At the same time, the empty take-up reel is replaced. During maintenance, the operating support plate can be opened to inspect components such as the heat-sealing bracket and the suction head 28. The PLC control unit communicates with the printer via the Modbus protocol and triggers the printing command based on the full roll signal of the heat-sealing packaging component 26 (detected by the encoder of the number of take-up turns). The parameter settings on the operating screen are managed with access control (such as administrator and operator permissions) to prevent accidental modification of key parameters (such as heat-sealing temperature). The printhead is cleaned regularly (wiped with an alcohol swab), the wear of the operating support plate clips is checked, and the touch accuracy of the operating screen is calibrated.

[0035] Preferably, in any of the above schemes, the upper wide-angle camera 23 is located on one side of the alternating shuttle platform 21. The upper wide-angle camera 23, the lower camera 24, the gantry robot 25, and the suction head 28 are all connected to the PLC control unit. The gantry robot 25 consists of a fixed connecting bracket, a motor-driven X-axis guide rail, and a Y-axis guide rail. The connecting bracket is fixedly installed inside the tape tray frame 22. The top of the connecting bracket is fixedly installed with a motor-driven Y-axis guide rail, and the top of the Y-axis guide rail is fixedly installed with an X-axis guide rail. The suction head 28 is fixedly installed at the output end of the X-axis guide rail. The suction head 28 consists of an integrated ZR axis, an integrated vacuum assembly, a moving camera, a panel light source, and five custom-designed nozzles. The integrated ZR axis is fixedly installed at the output end of the X-axis guide rail. The top of the integrated ZR axis is fixedly installed with an integrated vacuum assembly. The bottom of the integrated ZR axis is fixedly installed with a panel light source. One end of the panel light source is fixedly installed with a moving camera, and the bottom of the panel light source is fixedly installed with five custom-designed nozzles in a linear array.

[0036] The above technical solution employs the following: The upper wide-angle camera 23 (a 2000W global shutter camera, fixed at the top of the tape-and-reel frame 22, located above the alternating shuttle platform 21) is used to visually guide the robotic arm to perform disordered material grasping. The lower camera 24 (a 500W global camera, equipped with a ring light source, fixed below the gantry-type robotic arm 25) performs contour detection and secondary positioning of the material. The gantry-type robotic arm 25 consists of a connecting bracket (aluminum alloy material), an X-axis guide rail (servo motor driven), and a Y-axis guide rail (servo motor driven). The suction head 28 includes an integrated ZR axis, an integrated vacuum assembly (equipped with a pressure sensor), and a moving camera (a 500W global camera, capable of recognizing Mark point positioning and scanning various barcodes such as DM and QR)). The system features a panel light source (LED) and five linear array custom suction nozzles. The high resolution and wide-angle lens of the upper wide-angle camera 23 can cover the entire area of ​​the alternating shuttle platform 21, ensuring rapid material positioning. The disordered positioning function adapts to random material placement. The ring light source of the lower camera 24 eliminates surface reflection of the material and corrects suction deviation through secondary positioning. The high positioning accuracy of the X / Y axis guide rail of the gantry robot 25 ensures the accuracy of material gripping and placement, adapting to the needs of precision tape taping. The five suction nozzles of the suction head 28 can grip five materials (such as IC chips and auxiliary components) simultaneously, increasing gripping efficiency by 5 times. The integrated ZR axis enables material rotation adjustment. The integrated vacuum component monitors the gripping status. The moving camera can scan codes for traceability. The panel light source ensures sufficient light for scanning and detection.

[0037] The upper wide-angle camera 23, based on machine vision principles, captures images of the materials on the alternating shuttle platform 21 and transmits them to the vision processing module of the PLC control unit. The module identifies the material's position and posture using a template matching algorithm and outputs disordered positioning coordinates. The lower camera 24 captures images of the grasped materials, extracts the contours using an edge detection algorithm, compares them with standard contours, and calculates the deviation value. The PLC controls the gantry robot 25 to perform secondary positioning correction along the ZR axis. The X / Y axis guide rails of the gantry robot 25 are based on servo motors and ball screw drives. The PLC sends pulse signals to control the motor rotation, achieving linear positioning. The vacuum component of the suction head 28 generates negative pressure through a vacuum pump to adsorb materials. A pressure sensor provides feedback on the vacuum level. The moving camera captures the material barcode and uploads the data. The alternating shuttle platform 21 transports the materials to below the upper wide-angle camera 23, where the camera captures images of the materials. The vision module completes disordered positioning and transmits the coordinates to the PLC. The PLC controls the gantry robot 25 to move above the materials and capture the panel light from the suction head 28. The power source is turned on, the five suction nozzles are aligned with the material, the vacuum assembly starts to adsorb the material, the pressure sensor confirms successful adsorption, the robot arm moves the material to above the lower camera 24, the lower camera captures an image, completes contour detection and secondary positioning, the ZR axis rotates to adjust the material posture, if the detection is OK, the robot arm moves the material into the material strip groove of the heat-sealing packaging assembly 26, if the detection is NG, the robot arm places the material on the tray 27, the moving camera scans the material barcode during the gripping process, the data is uploaded to the EMS system, the vision processing module of the PLC control unit adopts a multi-threaded algorithm to simultaneously process the image data of the upper wide-angle camera 23 and the lower camera 24, the X / Y axis of the gantry robot arm 25 adopts a PID + feedforward control algorithm, adjusts the motor speed according to the deviation between the target position and the current position (detected by the grating ruler) to ensure positioning accuracy, the vacuum pressure of the suction head 28 is detected by the PLC analog input module, if it is lower than the threshold, the re-grip process is triggered, the camera is periodically calibrated, the lens focal length and light source brightness are adjusted to ensure positioning and detection accuracy.

[0038] Preferably, in any of the above embodiments, the heat-sealing packaging assembly 26 includes a heat-sealing bracket fixedly installed inside the tape-making machine frame 22. A material belt power motor is fixedly installed at one end of the bottom of the heat-sealing bracket. A conveyor wheel for conveying the material belt is fixedly installed at the output end of the material belt power motor through a pulley set. A track adjustment handwheel is fixedly installed at one end of the heat-sealing bracket. A heat-sealing fine-tuning handwheel fixedly installed with the heat-sealing bracket is provided on one side of the track adjustment handwheel. An empty material belt unwinding wheel fixedly installed with the tape-making machine frame 22 is provided on one side of the heat-sealing bracket. A full material belt take-up wheel fixedly installed with the tape-making machine frame 22 is provided on the other side of the heat-sealing bracket. A film unwinding wheel fixedly installed with the tape-making machine frame 22 is provided above the full material belt take-up wheel.

[0039] The above technical solution is adopted: the heat-sealing bracket (made of stainless steel) of the heat-sealing packaging component 26 has a material belt drive motor (servo motor) fixed at the bottom, and the output end is connected to the conveyor wheel (made of rubber) through a pulley set. One end of the bracket is equipped with a track adjustment handwheel, and the other side is equipped with a heat-sealing fine-tuning handwheel. Empty material belt unwinding wheel and full material belt take-up wheel (equipped with torque controller) are fixed on both sides of the bracket respectively. A film unwinding wheel is set above the full material belt take-up wheel. The heat-sealing bracket is equipped with a temperature controller and a temperature and pressure monitoring sensor. The stainless steel heat-sealing bracket is resistant to high temperature and corrosion, and provides stable support for the heat-sealing components. The material belt drive motor drives the conveyor wheel to transport the material belt through the pulley set, which is compatible with material belts of different specifications. The track adjustment handwheel adjusts the width of the conveyor track to accommodate changes in conveyor belt size. The heat sealing fine-tuning handwheel adjusts the heat sealing knife pressure to ensure a tight fit between the film and the conveyor belt without air bubbles. The empty conveyor belt unwinding wheel and the full conveyor belt take-up wheel work together to achieve continuous unwinding and take-up of the conveyor belt. The torque controller ensures stable take-up tension and prevents the conveyor belt from stretching. The film unwinding wheel provides the heat sealing film. The temperature controller and temperature and pressure monitoring sensor ensure stable heat sealing temperature and pressure to prevent the conveyor belt from being burned or the heat sealing from being incomplete. It supports various specifications of tape and reel, including but not limited to IC products, auxiliary components, finished PCB boards, finished mid-frames, and other materials, realizing automatic tape and reel functions.

[0040] The tape drive motor receives pulse signals from the PLC, driving the conveyor wheels to rotate. The tape is released from the empty tape unwinding wheel and conveyed to the heat-sealing area via the conveyor wheels. The film is released from the film unwinding wheel, covering the tape surface. The temperature controller heats the heat-sealing knife, and the heat-sealing fine-tuning handwheel adjusts the heat-sealing knife pressure, heat-pressing the film and tape together. The full-load tape take-up wheel, under the action of the torque controller, winds up the heat-sealed tape with stable torque. During the winding process, the torque controller adjusts the torque according to the change in the tape diameter (the torque increases as the diameter increases). The temperature and pressure monitoring sensor detects the heat-sealing temperature and pressure in real time, and the data is fed back to the PLC. If the threshold is exceeded, the machine stops and alarms. Empty tape is installed on the empty tape unwinding wheel, film is installed on the film unwinding wheel, and empty core is installed on the full-load tape take-up wheel. The track width is adjusted to match the tape size using the track adjustment handwheel. Heat-sealing fine-tuning... The handwheel sets the heat-sealing pressure, and the temperature controller sets the heat-sealing temperature. Upon starting the equipment, the material belt motor drives the conveyor wheel, synchronously conveying the material belt and film to the heat-sealing area. The heat-sealing knife heats and bonds the film and material belt. The bonded material belt is then wound up by the full-load take-up roller. The torque controller maintains stable winding tension. When the take-up roller reaches the set diameter, the PLC controls the motor to stop, the printer prints a label, and the operator replaces the empty roll core before restarting. The PLC control unit controls the heat-sealing temperature via the temperature control module, using a PID algorithm to adjust the heating power based on the temperature value fed back by the temperature and pressure monitoring sensor. The winding torque is communicated with the PLC through the torque controller, automatically adjusting the torque based on the full-load take-up roller diameter (detected by an encoder). The temperature controller (using a standard thermometer) and pressure sensor are calibrated periodically, and the surface of the heat-sealing knife is cleaned.

[0041] The working principle of this novel tape-and-reel packaging detection line is as follows: After the power is turned on, the drive box inside the receiving frame 11 of the receiving machine 1 starts, and the conveyor belt assembly of the feeding track 12 transports the fixture containing the PCB to the working range of the four-axis robot 13. The PLC control unit simultaneously activates all components of the equipment. The four-axis robot 13 uses the vacuum suction cup assembly on the connecting plate to pick up the fixture. After the integrated vacuum detection sensor confirms that the vacuum level meets the standard, it moves the fixture. At the other end, the industrial barcode scanner scans the PCB panel code and uploads the data to the EMS system. Then, the fixture is placed on the alternating shuttle platform 21. The alternating shuttle platform 21 conveys the fixture and materials to the tape machine 2. The wide-angle camera 23 at the top of the tape machine frame 22 captures images of the materials. The visual algorithm completes the disordered positioning and feeds back to the PLC. The PLC controls the gantry robot 25 to move above the materials. The five customized suction nozzles of the suction head 28 adsorb the materials under the action of the integrated vacuum component. The moving camera scans the material barcode simultaneously. The panel light source provides sufficient light. The robot moves the materials to below the lower camera 24. The lower camera performs contour detection and secondary positioning of the materials. If the detection is NG, the robot puts the materials into the tray 27. If the detection is OK, it moves to the heat sealing packaging component 26 and accurately puts the materials into the material tape groove. The material tape power motor drives the material tape to be conveyed. The film unwinding wheel releases the film. The temperature controller and heat sealing fine-tuning handwheel in the heat sealing bracket work together to achieve heat sealing. The full material tape winding wheel winds up the material tape. After full winding, the printer automatically prints the label. All structures work together to complete the entire tape packaging and inspection process. The empty fixture is recovered through the empty fixture discharge track 14 and the fixture material frame lifting mechanism 15.

[0042] Compared with the prior art, the present invention has the following advantages: 1. A gantry-type robotic arm 25 is installed inside the tape and reel packaging inspection line. The servo motor and lead screw inside the gantry-type robotic arm 25 improve the packaging speed of the equipment. An upper wide-angle camera 23 and a lower camera 24 are installed inside the tape and reel machine 2 to detect and position the materials to be tape and packaged. The accuracy of material picking is corrected by software based on the data feedback from the upper and lower camera components, ensuring packaging accuracy. At the same time, five suction nozzles are set on the suction head 28, which can pick up five products at the same time, improving packaging efficiency. By replacing manual inspection with automated detection and gripping packaging, labor and time costs can be effectively reduced, and the production efficiency of the tape and reel packaging inspection line can be increased.
