[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 As shown, the continuous terminal feeding mechanism includes a worktable 1, on which an injection molding machine 2 is mounted. The worktable 1 also includes a receiving module 3, an adjusting bracket 4, a receiving servo module 12, a detection CCD 13, a product unloading module 19, and a terminal feeding module 20. The terminal feeding module 20 is mounted on a fixed bracket 14, on which a mold positioning CCD 15 is mounted. Two terminal separation cylinders 16 are mounted on the fixed bracket 14, and a first terminal picking module 17 and a second terminal picking module 18 are respectively mounted on the two terminal separation cylinders 16. A vibratory feeder 5 is mounted on the adjusting bracket 4, on which a linear feeder 6 is mounted. A terminal guide rail 7 is mounted on the linear feeder 6, and a terminal sensor 8 is mounted on the terminal guide rail 7. A downward-pressing needle module 9 is mounted on the adjusting bracket 4. A first receiving fixture 10 and a second receiving fixture 11 are mounted on the moving platform of the receiving servo module 12.

[0018] As a technical optimization of this utility model, the linear feeder 6 and the terminal guide rail 7 are installed sequentially on the vibratory feeder 5 along the terminal conveying direction. The vibratory feeder 5, the linear feeder 6, and the terminal guide rail 7 together form the terminal conveying channel. The terminal sensor 8 is installed at the end of the terminal guide rail 7. The terminal sensor 8 detects in real time whether the terminal at the end of the terminal guide rail 7 is in place. When the terminal is detected, it immediately sends a signal to the external control system to ensure that the subsequent process starts accurately, avoids empty operation caused by the terminal not being in place or track blockage caused by excessive terminals, and improves the accuracy of feeding. The terminal sensor 8 is used to detect whether the terminal is conveyed to the designated receiving position.

[0019] As a technical optimization of this utility model, the working end of the pressing needle module 9 faces the terminal arrangement area at the end of the terminal guide rail 7. After receiving the arrival signal from the terminal sensor 8, the pressing needle module 9 drives the needle structure to move upward, pressing down and separating the terminals at the end of the terminal guide rail 7, and sorting the terminals into a single and neat arrangement. The pressing needle module 9 is used to separate the stacked terminals at the end of the terminal guide rail 7 into a single arrangement.

[0020] As a technical optimization of this utility model, the first receiving fixture 10 is used to receive terminals conveyed from the terminal guide rail 7, the second receiving fixture 11 is used to receive terminals conveyed from the terminal guide rail 7, and the detection CCD 13 is used to detect the terminals in the receiving fixtures. The detection CCD 13 acquires images of the terminals in the first receiving fixture 10 and the second receiving fixture 11, detects the number of terminals, their arrangement, and whether there are any problems such as skewness or damage, and transmits the detection data to the external control system. If a defective terminal is found, the control system immediately triggers an alarm and controls the equipment to stop, which facilitates timely handling by the staff, prevents defective terminals from entering the injection molding process, reduces the product defect rate, and ensures product quality. The detection CCD 13 is electrically connected to the external image processor.

[0021] As a technical optimization of this utility model, the first terminal picking module 17 is used to connect the transfer process of terminals from the receiving module 3 to the injection molding machine 2. When the terminals in the receiving module 3 are qualified, the two terminal separation cylinders 16 drive the first terminal picking module 17 and the second terminal picking module 18 to move respectively. The driving cylinders of the first terminal picking module 17 and the second terminal picking module 18 drive the clamping claw to clamp the terminals. Then the terminal separation cylinder 16 drives the terminal picking module to move towards the injection molding machine 2. Combined with the positioning data provided by the mold positioning CCD 15, the terminals are accurately placed into the mold of the injection molding machine 2. The two terminal picking modules work alternately to improve the picking and unloading efficiency and match the production rhythm of the injection molding machine 2. The second terminal picking module 18 is used to connect the transfer process of terminals from the receiving module 3 to the injection molding machine 2.

[0022] As a technical optimization of this utility model, the product unloading module 19 is used to transport the injection-molded terminal products to the designated storage area. The product unloading module 19 transports the molded products from the discharge end of the injection molding machine 2 to the designated storage area to realize automated product unloading. The top of the first receiving fixture 10 and the second receiving fixture 11 are both provided with positioning grooves that are compatible with the terminals.

[0023] In use, this invention first pours a batch of terminal raw materials into a vibratory feeder 5. After being powered on, the vibratory feeder 5 vibrates through its built-in vibration component, causing the internal terminals to move and be sorted according to a preset direction (e.g., PIN pins facing the same direction). The sorted terminals are then conveyed to a linear feeder 6. The vibratory feeder 5 can adjust its vibration frequency according to terminal specifications (e.g., size, weight) to adapt to the sorting requirements of different types of terminals. It can sort hundreds of terminals per minute, significantly improving initial processing efficiency and avoiding directional confusion caused by manual sorting. After receiving the terminals, the linear feeder 6 smoothly and continuously conveys them to the terminal guide rail 7 through linear vibration. Its feeding speed can match the rhythm of subsequent processes, preventing terminals from piling up or accumulating during transport. To ensure stable operation of subsequent processes, the terminal guide rail 7 guides the terminals conveyed by the linear feeder 6, ensuring that the terminals move along a fixed path to the end. The terminal sensor 8 detects in real time whether the terminals at the end of the terminal guide rail 7 are in place. When a terminal is detected, it immediately sends a signal to the external control system to ensure accurate start of subsequent processes, avoiding empty operation due to terminals not being in place or track blockage due to excessive terminals, thus improving feeding accuracy. After receiving the arrival signal from the terminal sensor 8, the pressing needle module 9 drives the needle structure to move upward, pressing down and separating the terminals at the end of the terminal guide rail 7, sorting the terminals into a single and neatly arranged state. The receiving servo module 12 drives the first receiving fixture 1 on the moving table. The first receiving fixture 10 and the second receiving fixture 11 alternately move to the end of the terminal guide rail 7 to receive terminals. When the first receiving fixture 10 is full of terminals, the receiving servo module 12 immediately drives it to move, while the second receiving fixture 11 moves to the receiving position, achieving seamless connection between receiving and conveying. Compared with the single fixture receiving mode, this reduces the interruption time of loading and improves the receiving efficiency. Moreover, the receiving servo module 12 adopts a servo drive method, which has high positioning accuracy and can ensure that the receiving fixture accurately connects to the end of the terminal guide rail 7, avoiding the terminals from falling or being damaged by collision during the receiving process. After the receiving servo module 12 conveys the receiving fixture carrying the terminals, the detection CCD 13 performs image acquisition on the terminals in the first receiving fixture 10 and the second receiving fixture 11, detecting the number, arrangement, and other information of the terminals. The system detects any issues such as misalignment or damage and transmits the detection data to an external control system. If a defective terminal is detected, the control system immediately triggers an alarm and stops the equipment, allowing for timely handling by staff. This prevents defective terminals from entering the injection molding process, reducing product defect rates and ensuring product quality. The fixed bracket 14 is installed on the terminal feeding module 20, providing a stable mounting base for the mold positioning CCD 15 and the two terminal separation cylinders 16, reducing shaking of components during operation and improving overall structural stability. The modular design reduces manufacturing and maintenance costs while improving equipment reliability and lifespan. The mold positioning CCD 15 captures the mold position of the injection molding machine 2 in real time and obtains precise mold coordinates through image recognition technology.The coordinate data is transmitted to the control system to provide positioning information for the feeding positions of the first terminal picking module 17 and the second terminal picking module 18, ensuring that the terminals are accurately placed into the designated area of ​​the mold and improving injection molding accuracy. High-precision positioning technology ensures precise alignment of the PIN pins and terminal blocks, improving pin insertion accuracy and product quality. Once the terminals in the receiving module 3 pass inspection, the two terminal separation cylinders 16 drive the first terminal picking module 17 and the second terminal picking module 18 to move, respectively. The clamping claws grip the terminals, and then the terminal separation cylinder 16 moves the terminal picking module towards the injection molding machine 2. Using the positioning data provided by the mold positioning CCD 15, the terminals are precisely placed into the mold of the injection molding machine 2. The two terminal picking modules work alternately, improving material handling efficiency and matching the production rhythm of the injection molding machine 2. Automated operation reduces manual intervention and improves production efficiency. After the injection molding machine 2 completes the injection molding process, the product unloading module 19 transports the molded product from the discharge end of the injection molding machine 2 to the designated storage area, achieving automated product unloading.
