Description

Technical Field

[0001] The present invention relates to the field of Bluetooth adapters, and more specifically, to an automatic Bluetooth adapter assembly machine and an assembly method. Background Art

[0002] The birth of the Bluetooth adapter automatic assembly machine and its assembly method is to deal with the problems of low efficiency, unstable quality and high labor cost in the traditional manual assembly mode. The traditional Bluetooth adapter assembly process usually relies on manual operation, including the selection, alignment, assembly and detection of parts. Although this mode is flexible, it relies heavily on the technical level of the operator, and has the disadvantages of low production efficiency, low assembly accuracy and poor product consistency. In addition, with the widespread application of Bluetooth devices and the rapid growth of market demand, traditional assembly methods are difficult to meet the needs of large-scale and standardized production. The automatic assembly machine realizes the automatic alignment, fixation and detection of each component of the Bluetooth adapter through the combination of robotic arms, visual systems, sensors and high-precision process equipment. This automation technology not only greatly improves production efficiency, but also improves assembly accuracy and product consistency, and can meet the requirements of modern industry for efficient and high-quality production. At the same time, the automatic assembly machine effectively reduces the dependence on manual labor and reduces quality problems caused by manual fatigue or misoperation.

[0003] However, the existing automatic assembly machines still have some shortcomings. The biggest shortcoming is that the equipment development and maintenance costs are high, and the initial investment is large, which may bring high financial pressure, especially for small and medium-sized enterprises. In addition, the equipment has limited flexibility when facing different models or new Bluetooth adapter products, and often needs to redesign or debug the production line, which to a certain extent limits its ability to adapt to rapid market changes.

[0010] Preferably, the automatic assembly method of a Bluetooth adapter comprises the following steps:

[0011] S1. Place the various components of the Bluetooth adapter, including the housing, PCB board, and connector, into the corresponding vibration screening mechanism silo, and adjust the parameters of the vibration screening mechanism to ensure that the components are output in the specified direction;

[0012] S2. Start the vibration screening mechanism, and use electromagnetic vibration to move the parts on the screening track and arrange them in the direction of output. The photoelectric sensor detects the number of parts in real time to maintain the continuity of feeding;

[0013] S3. The screened parts enter the automatic feeding mechanism and are transported one by one to the designated position of the assembly module by the robotic arm. The material sensor detects whether the screened parts are in place correctly;

[0014] S4. The robotic arm of the assembly module grabs the screened parts from the loading area, and sequentially completes the assembly operations of PCB board fixing, connector installation, housing buckling, positioning fixture and pressure sensor;

[0015] S5. The assembled Bluetooth adapter enters the inspection module, where an industrial camera checks whether the appearance is complete. Then, an electrical performance test is performed to ensure that the circuit connection and function are normal, and unqualified products are removed;

[0016] S5. Products that pass the inspection enter the finished product collection area through the conveyor belt, and are printed with labels as needed and then conveyed to the packaging station.

[0017] Preferably, the vibration screening mechanism screening components comprises the following steps:

[0018] S2-1. Pour the Bluetooth adapter parts into the movable frame installed on the upper end surface of the frame, and make the screening plate, guide slope, guide cavity and collection trough mechanism clean and unobstructed; start the motor and prepare for vibration screening;

[0019] S2-2. After the motor is started, the output shaft drives the drive rod to move up and down, and the drive rod is inserted into the movable sleeve, so that the screening plate produces periodic vibration; the spring in the movable sleeve provides buffering and resilience, so that the vibration is stable and the mechanism is protected;

[0020] S2-3. As the sieve plate vibrates, the parts placed in the movable frame are gradually screened; parts that meet the sieve hole size fall into the frame through the sieve plate, and parts that do not meet the requirements stay at the upper end of the sieve plate;

[0021] S2-4. The screened parts slide along the guide slope into the guide cavity that matches the position; when the parts pass through the guide cavity, they are automatically arranged into a single layer due to the slope design and gravity; the parts in the guide cavity enter the peripheral collection tank and are subsequently transported to the automatic feeding mechanism;

[0022] S2-5. During the vibration screening process, the second latch at the lower end of the screening plate engages with the first latch on the inner wall of the frame to ensure that the screening plate is fixed and prevented from shifting; after the screening is completed, the screening plate is removed for cleaning and maintenance by unlocking the latch and removing the remaining parts and debris in the sieve hole;

[0023] S2-6. The parts and foreign matter that have not passed the screening are left in the movable frame, taken out and recycled, so that the next use of the vibration screening mechanism is smooth;

[0024] S2-7. According to the screening effect of the parts, adjust the output power of the motor to change the vibration frequency of the screening plate and optimize the screening efficiency; in addition, replace the screening plate with different mesh sizes according to the size and characteristics of the parts.

[0025] Preferably, the automatic feeding mechanism feeding includes the following steps:

[0026] S3-1. The screened parts are evenly placed into the storage frame so that the parts are not piled up in the storage frame;

[0027] S3-2. Start the first motor in the storage frame to drive the screen plate to rotate; the rotation of the screen plate will move the parts in the storage frame, so that the parts gradually enter the guide cavity, while eliminating the accumulation and stuck parts;

[0028] S3-3. Parts slide from the guide cavity into the guide tube in sequence, and enter the interior of the loading frame through gravity and an appropriate inclination angle, so that the conveying path is unobstructed;

[0029] S3-4. Start the second motor at the outer end of the loading frame, and the output shaft drives the spiral plate to rotate; the rotation of the spiral plate will push the parts entering the loading frame forward according to the specified trajectory to form a single-layer continuous output;

[0030] S3-5. According to the conveying requirements and the specifications of the parts, the output power of the second motor and the speed of the spiral plate are adjusted to optimize the conveying speed of the parts to avoid accumulation and interruption of parts during the conveying process;

[0031] S3-6. The parts are delivered to the assembly module through the outlet of the loading frame.

[0032] Preferably, the automatic assembly of parts by the assembly module comprises the following steps:

[0033] S4-1. The parts that have passed the screening and feeding mechanism are transported to the inner cavity of the first frame of the assembly module, and the first limit bar and the second limit bar cooperate to form an insertion cavity to preliminarily position the parts, so that they are arranged neatly and in the same direction;

[0034] S4-2. Start the first motor at the outer end of the first frame, the output shaft drives the spiral rod to rotate, and the spiral rod gradually pushes the parts in the insertion cavity to the assembly position in the horizontal direction; during the pushing process, the limit strip and the inner wall of the frame keep the parts in the accurate direction and position;

[0035] S4-3. The parts that reach the assembly position are grabbed by the robot arm; the robot arm automatically locates the parts according to a preset program, grabs the parts by a precision fixture, and moves the parts to the assembly area of ​​the second frame;

[0036] S4-4. The push plate in the second frame is reset to the initial position under the action of the spring. When the robot arm puts the component into the through cavity, the push plate slightly compresses the spring under the weight of the component, so that the component is accurately positioned in the through cavity;

[0037] S4-5. The second motor at the upper end of the second frame is started, and the output shaft drives the pressure plate to move downward, pressing the parts to the assembly position of the second frame; the pressure plate controls the magnitude of the applied pressure under the buffering effect of the spring, so that the parts are firmly fixed, while avoiding excessive pressure to damage the parts;

[0038] S4-6. The robot grabs other parts according to the assembly steps and places them one by one into the assembly position of the second frame, repeats the push plate positioning and pressure plate fixing operations until all parts are installed;

[0039] S4-7. After the assembly is completed, the pressure plate is reset upward to the initial position, and the push plate slides downward under the action of the spring, pushing the assembled Bluetooth adapter out from the bottom of the cavity and sending it to the finished product conveyor belt through the outlet below.

[0040] Preferably, the detection process of the detection module includes the following steps:

[0042] S5-2. Detect the appearance of the Bluetooth adapter by using visual sensors installed in the detection module, including cameras and photoelectric sensors; check whether there are scratches, cracks, deformations and any other visible defects on the appearance of the adapter; use image processing algorithms to analyze the captured images and compare them with preset standard images to determine whether they meet quality requirements; if appearance defects are found, automatically mark the adapter as a defective product and remove it by an air blowing device and a robotic arm;

[0043] S5-3. The detection module is provided with a precision laser sensor and a touch sensor to detect whether the size of the Bluetooth adapter meets the standard requirements, including the size of the adapter socket, the shell thickness, and the hole position accuracy, so that the accuracy of the parts meets the assembly requirements; the detected size data is compared with the preset standard value. If there is a deviation, the system will determine it as unqualified, and automatically reject it and alarm;

[0044] S5-4. The adapter passes through the circuit detection equipment to check whether the electrical performance of the adapter is normal; including voltage, current and signal strength tests, so that the internal circuit works normally and avoids electrical failures; by setting up wireless signal testing equipment, the communication performance and signal reception range of the Bluetooth adapter are detected to confirm whether the Bluetooth connection of the adapter is stable and whether the transmission rate meets the standard; if abnormal electrical performance and wireless signal are detected, the system will mark it as unqualified and send the adapter to the recycling channel and repair channel;

[0045] S5-5. Use air pressure and hydraulic equipment to simulate the external force of the adapter in actual use, test the pressure resistance of the shell and the durability of the socket; perform durability tests by applying pressure and vibration multiple times to ensure the reliability of the adapter in long-term use;

[0046] S5-6. The test data of each inspection step, including appearance, size, and electrical performance, will be recorded in real time in the control system. After the inspection process is completed, a quality report will be generated to indicate whether each adapter is qualified. The report content includes the number of unqualified products, the type of problem, and the cause of the abnormality.

[0049] (2) In the new design, the vibrating screening mechanism is equipped with a combination of a movable frame and a driving rod, as well as a spring adjustment device, which makes the screening process more precise and avoids over- or under-feeding of parts. In addition, the design of the spiral plate and screening plate in the automatic feeding mechanism ensures uniform feeding and efficient conveying of parts, reduces production stoppages caused by overloading or accumulation, and thus improves production efficiency.

[0050] (3) The new inspection module uses advanced visual sensors and electrical performance testing equipment, which can monitor and detect the appearance, size, electrical performance, wireless signals, etc. of parts in real time during the automatic assembly process, and promptly detect and remove unqualified products. This not only improves the quality control capabilities of the products, but also effectively prevents unqualified products from flowing into the downstream links.

[0051] (4) The newly designed control system realizes the intelligent coordination of vibration screening, automatic feeding, assembly and detection modules. Through real-time data monitoring and dynamic adjustment of equipment, the system can automatically adjust the production rhythm and make adjustments based on real-time detection results to optimize production efficiency and product quality. In addition, the system also provides detailed quality data recording and analysis functions to provide support for subsequent quality improvement and process optimization.

[0052] (5) The new design strengthens the fault detection and alarm functions, including automatic monitoring of equipment failures, component jams, production anomalies, etc. When a failure occurs, the system automatically stops the relevant modules and issues an alarm prompt, avoiding unexpected losses during the production process. In addition, the safety interlock design ensures safety during the production process and avoids personal injury or equipment damage.

[0053] (6) The new design takes into account a variety of production needs. The automatic feeding mechanism and vibration screening mechanism have a wider adjustment range and can adapt to parts of different specifications and types. This greatly improves the adaptability of the production line and can quickly switch production modes to meet the needs of different product batches. BRIEF DESCRIPTION OF THE DRAWINGS

The report content includes the number of unqualified products, the type of problem, and the cause of the abnormality.

[0099] Specifically, the vibration screening mechanism and the automatic feeding mechanism are connected through a control system, and the coordinated realization of automated production includes the following specific measures:

[0100] A. Hardware connection: Equip the vibration screening mechanism and automatic feeding mechanism with independent motor control modules (such as frequency converter or servo drive for driving motor), and connect them to the central control system (such as PLC or industrial computer) through signal lines.

[0101] Photoelectric sensors, position sensors and speed sensors are installed to detect the output of vibration screening parts, material guiding progress and feeding status respectively.

[0102] The data of each module is transmitted to the central control system in real time through a communication interface (such as RS485, CAN bus or industrial Ethernet).

[0103] B. Control system programming: Develop a logic program in the control system to determine the screening status of the vibration screening mechanism and the feeding status of the automatic feeding mechanism by reading sensor data.

[0104] Program the start sequence: When the vibration screening mechanism starts running, the system detects whether the screened parts have reached the set number, and then issues a command to start the spiral conveying process of the feeding mechanism to ensure that the parts are transported according to the beat.

[0105] Design exception handling logic: If it is detected that the vibration screening mechanism is stuck or the output of parts is insufficient, the feeding mechanism will be suspended and an alarm signal will be issued.

[0106] C. Parameter coordination: Adjust the frequency of the vibration screening mechanism motor to match the parts screening efficiency with the conveying rate of the automatic feeding mechanism to avoid production interruptions caused by excessive or insufficient parts feeding.

[0107] Set up a buffer zone: Design a small storage area between the vibration screening mechanism and the automatic feeding mechanism. When the material supply is insufficient, the buffer zone will temporarily provide parts. When the material supply is excessive, the parts will be temporarily stored to ensure a steady production rhythm.

[0108] D. Real-time monitoring and optimization: The control system displays the operating status of vibration screening and automatic feeding in real time, including data such as the number of parts, screening frequency, and conveying speed, for the operator to view and adjust.

[0109] Data recording function: Store key data in the screening and feeding process to analyze production bottlenecks and optimize parameter configuration.

[0110] E. Automatic synchronous operation: The synchronization between modules is realized through the logic program: after the vibration screening mechanism reaches the set number, it automatically sends a signal to the feeding mechanism to start the conveying process.

[0111] Unified start and stop conditions: The control system is equipped with a unified start / stop button. When one module stops, it automatically instructs the other module to enter standby mode to avoid the accumulation or loss of parts due to separate operation.

[0112] F. Fault alarm and safety interlock When the vibration screening mechanism or feeding mechanism fails (such as material jamming, overload, insufficient material, etc.), the system immediately stops the operation of the relevant modules and issues an alarm.

[0113] Safety interlock design: If an abnormal situation is detected or the emergency stop button is triggered, the control system will shut down both mechanisms at the same time to ensure equipment and production safety.

[0114] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
