[0032] like Figures 1 to 4 As shown, according to an embodiment of the utility model, a material receiving and caching machine is proposed, and the material receiving and caching device 100 includes a bracket assembly 10, a fixed pulley block 20 and a movable pulley block 30, the bracket assembly 10 includes a bracket body, the bracket body is connected with a first rotating shaft 14 and a second rotating shaft 15 arranged parallel to the first rotating shaft 14 and spaced apart, along the direction from the first rotating shaft 14 to the second rotating shaft 15, the second rotating shaft 15 is slidably connected to the bracket body, the fixed pulley block 20 is arranged on the first rotating shaft 14, the fixed pulley block 20 includes at least one fixed winding wheel 21, the movable pulley block 30 is arranged on the second rotating shaft 15, the movable pulley block 30 includes at least one moving winding wheel 31, the fixed winding wheel 21 and the moving winding wheel 31 are cooperatively arranged, and are used to allow the terminal to pass through the fixed winding wheel 21 and the moving winding wheel 31 in sequence.

[0033] According to the material receiving and caching device 100 of the utility model, by configuring a slidable second rotating shaft 15 on the bracket assembly 10, the movable pulley block 30 can adjust its position according to the speed and quantity of the terminal discharge. This adaptive moving mechanism enables the equipment to flexibly respond to different discharge speeds and discharge volumes, thereby effectively reducing material accumulation and equipment shutdown caused by speed mismatch. The coordinated setting of the fixed pulley block 20 and the movable pulley block 30 ensures the stability and smoothness of the terminals during the entire transmission process, and reduces material loss caused by improper guiding. The utility model improves the adaptability and processing capacity of the equipment by adding the dynamic adjustment function of the pulley block. For high-speed or large-volume production environments, this design can ensure continuous and stable production and avoid the problems of material congestion and reduced processing efficiency that may be encountered in conventional equipment.

[0034] It is understandable that terminals mostly refer to wiring terminals, also called wiring terminals, which are mainly used to transmit electrical signals or conduct electricity. When the existing cache machine is working, the staff needs to hold the terminal wire to perform the cache work.

[0035] In some embodiments, the support body includes a column 11, and the first rotating shaft 14 and the second rotating shaft 15 are respectively connected to the column 11. The column 11 is made of high-strength material, such as steel or aluminum alloy, to ensure the stability and durability of the entire support.

[0036] Specifically, there are two columns 11, and the two columns 11 are arranged in parallel and spaced apart. The receiving and caching device 100 includes a first rotating shaft 14 and two rotating shafts. The two ends of the first rotating shaft 14 are respectively connected to the two columns 11, and the two second rotating shafts 15 are connected to the two columns 11 one by one. There are two fixed pulley blocks 20, and the two fixed pulley blocks 20 are arranged on the first rotating shaft 14 at intervals. There are two movable pulley blocks 30, and the two movable pulley blocks 30 are arranged on the two second rotating shafts 15 in a one-to-one correspondence. The two ends of the first rotating shaft 14 are respectively fixed on the two columns 11. Such a layout not only provides additional mechanical stability, but also makes the first rotating shaft 14 more stable during operation, reducing operational problems caused by shaft offset or vibration. At the same time, two fixed pulley blocks 20 are arranged on the first rotating shaft 14 at intervals, and one movable pulley block 30 is arranged on each of the two second rotating shafts 15. This layout enables the device to process two terminal lines at the same time, thereby improving the working efficiency and output capacity of the device. By configuring two sets of fixed pulleys 20 and movable pulleys 30 at the same time, the receiving material buffer device 100 can process two terminals at the same time, which not only doubles the production efficiency, but also improves the overall output capacity of the production line. Furthermore, the receiving material buffer device 100 has the function of being able to process two terminals with different processing requirements at the same time. For terminals that do not need to be rewound, the receiving material buffer device 100 guides the terminals to the material tray through the fixed pulleys 20 and the movable pulleys 30 after passing through the post-processing device. For terminals that need to be rewound, the device guides the terminals to the rewinding device through another set of movable pulleys 30 and the fixed pulleys 20. The rewinding device is responsible for adjusting the winding direction of the terminals or rearranging the terminals to meet specific storage or subsequent processing requirements, and then collecting them into the material tray.

[0037] In some embodiments, the receiving material buffer device 100 includes a cleaning component 40, and the cleaning component 40 includes a connecting structure 41 and an air suction device arranged on the connecting structure 41, and the connecting structure 41 is connected to the bracket body to provide support for the cleaning component 40. The air suction device includes a plurality of first air suction ports 421 and second air suction ports 422 arranged opposite to each other, and a guide channel 43 is formed between the first air suction ports 421 and the second air suction ports 422, and the guide channel 43 is used to allow the terminal to pass through. The cleaning component 40 includes a connecting structure 41, and two groups of air suction ports (first air suction ports 421 and second air suction ports 422) arranged opposite to each other are provided on the connecting structure 41. The guide channel 43 formed between the two air suction ports is specifically used to guide the terminal to pass smoothly, and at the same time, remove dust and oil stains on the terminal. The inner wall of the guide channel 43 is designed to be smooth and have a certain guide curvature, which helps to reduce the friction and wear of the terminal when passing through, while ensuring the linearity and anti-kink performance of the terminal. By effectively removing dust and oil from the terminals, the cleaning assembly 40 helps maintain the cleanliness and high quality of the product, reducing the potential for problems in subsequent processing, such as uneven coating or electrical failures.

[0038] Specifically, the suction device is a vacuum generator. As the core of the suction device, the vacuum generator can provide stable and powerful suction to effectively remove dust and other tiny particles from the terminal. The selection of the vacuum generator should take into account its suction force, energy efficiency and ease of maintenance. In addition, an air flow channel is provided inside the connecting structure 41 to ensure that the air flow is evenly distributed in the first and second air intake ports 422, so as to maximize the dust collection efficiency. The design of the air flow channel should also take into account the smoothness of the air flow to reduce the mechanical stress on the terminal.

[0039] Specifically, the cleaning component 40 also includes a guide structure 44, which is arranged on the connecting structure 41, and the guide structure 44 is located in the extension direction of the guide channel 43. The guide structure 44 is designed as a channel with a certain curved shape, which is installed on the connecting structure 41 and is located in the extension direction of the guide channel 43. This design ensures that the terminal can move smoothly along the predetermined path after entering from the suction port, and effectively prevents the terminal from twisting or winding. The guide structure 44 is tightly integrated with the suction device to ensure that the terminal can be guided and cleaned at the same time when passing. This integrated design optimizes the space utilization of the equipment and improves the operating efficiency. Through the precise guide structure 44, the terminal can maintain the correct path, reduce errors and material losses during the processing process, and improve the quality of the final product.

[0040] Specifically, the cleaning assembly 40 also includes a collection box 45, which is connected to the suction device through an air pipe. The collection box 45 is designed to be easy to install and clean, and is usually made of durable materials such as engineering plastics or stainless steel. The size and shape of the collection box 45 are optimized according to the amount of terminal processing and the suction force of the suction device to ensure maximum dust and impurity collection. The collection box 45 is connected to the suction device through an air pipe. This air pipe should use flexible materials such as reinforced plastics or rubber to facilitate installation and maintenance while ensuring air tightness and durability. An efficient filtering system is installed inside the collection box 45, which can intercept fine dust particles and pollutants and prevent them from re-entering the working environment. The filtering system should be designed to be easy to replace and clean to maintain dust collection efficiency. The collection box 45 is installed on the side of the column 11 for easy access by operators for regular cleaning and maintenance. The integrated collection box 45 effectively collects and isolates dust and oil stains generated during terminal processing, reducing their impact on the production environment and product quality. Through effective collection and filtration systems, pollutants in the air in the working area are reduced, providing operators with a cleaner and safer working environment.

[0041] In some embodiments, the material receiving and caching device 100 further includes a measuring component 50, which is connected to the bottom of the support assembly 10 and is used to measure the distance from the second rotating shaft 15 to the bottom of the support assembly 10. The measuring component 50 is installed at the bottom of the support assembly 10 to ensure that its position is fixed and accurately aligned with the second rotating shaft 15. This installation method helps to reduce the impact of external factors on measurement accuracy. The measurement results are transmitted to the central control system in real time via an electronic interface (such as USB or wireless connection). The central control system can adjust the position of related components based on the measurement data to optimize the operating efficiency and accuracy of the equipment. By setting a threshold, when the measured distance deviates from the preset range, the automatic control system automatically adjusts the position of the second rotating shaft 15 or issues a maintenance prompt to ensure that the material receiving and caching device 100 continues to operate in the best state.

[0042] Specifically, the central control system can also be connected to the turntable rewinding machine for subsequent processing of the material receiving and buffering device 100. When the measured spacing deviates from the preset range, the collecting speed of the receiving terminal of the turntable rewinding machine can be adjusted to control the material receiving and buffering device 100 to continue to operate in the optimal state.

[0043] Specifically, the measuring component 50 includes a laser sensor unit, a laser light projector of which is arranged facing the second rotating shaft 15 . The laser sensor unit is a laser sensor that can measure the lifting distance of the second rotating shaft 15 and further know the lifting distance of the movable pulley block 30 .

[0044] In some embodiments, the bracket assembly 10 includes a guide rail portion 12, which includes a guide rail 121 and a sliding bearing 122 connected to the guide rail 121 in a slidable manner, and the sliding bearing 122 is connected to the second rotating shaft 15. The guide rail portion 12 includes one or more precision guide rails 121, which are arranged on the side of the pillar and are usually made of wear-resistant materials, such as steel or industrial-grade aluminum alloy, to ensure durability and stability for long-term use. The sliding bearing 122 is designed to fit well with the shape of the guide rail 121, and can slide smoothly on the guide rail 121 to support the up and down sliding of the second rotating shaft 15. The combination of the precision guide rail 121 and the sliding bearing 122 provides stable and controllable movement, which is essential for maintaining the accuracy of the equipment when processing terminals, thereby ensuring product quality.

[0045] In some embodiments, the support assembly 10 further includes a counterweight 13, which is connected to the movable pulley block 30 and plays a counterweight balancing function to prevent the terminal from being pulled. The counterweight 13 includes an iron block, a lifting ring 131 and a rope. The lifting ring 131 is arranged on one side of the column 11, and the iron block is connected to the lifting ring 131 by a rope. Appropriate counterweights can balance the movement of the moving wheel assembly, prevent the equipment from swaying or deflecting during operation, and thus maintain the processing accuracy and stability.

[0046] In some embodiments, the support assembly 10 includes a base 60, and the column 11 is fixed to the base 60 in a vertical direction, and can be fixed by bolts or welding to provide additional support and stability. There may be pulleys for walking under the base 60.

[0047] In some embodiments, a limit assembly 70 is provided on the column 11, including an upper limit member and a lower limit member, and the upper limit member and the lower limit member are travel switches. When the second rotating shaft 15 slides beyond a certain threshold, the second rotating shaft 15 is limited to stop moving.

[0048] In the material receiving and caching device 100 of this embodiment, before the material receiving and caching device 100 is started, the worker takes two terminals and passes them through the guide channel 43 of the cleaning component 40 respectively. The cleaning component 40 uses a strong airflow to suck away the dust and oil stains on the terminals, and the cleaned dust and oil stains are collected in the collection box 45. The first terminal after cleaning passes through one of the fixed pulley blocks 20 and the movable pulley block 30, and is wound between the fixed winding wheel 21 of the fixed pulley block 20 and the movable winding wheel 31 of the movable pulley block 30 in sequence. Similarly, the second terminal passes through another fixed pulley block 20 and the movable pulley block 30, and is wound between the fixed winding wheel 21 of the fixed pulley block 20 and the movable winding wheel 31 of the movable pulley block 30 in sequence. The worker presses the start button, and the punching machine starts to discharge continuously. After the terminal comes out of the punching machine, it is cleaned by the air cleaning component 40. When the first terminal and the second terminal gradually increase during the continuous discharge process of the punching machine, the two movable pulley blocks 30 will move downward according to the increase of the terminals. The guide rail 12 guides the sliding of the two movable pulleys 30, and the counterweight 13 is used to balance the bracket assembly 10 to prevent the terminal from being pulled. During the up and down movement of the moving wheel assembly, the laser sensor detects the change in the distance between the moving wheel assembly and the base 60, and outputs the distance simulation to the PLC (automatic control system), and then the turntable rewinding machine can adjust the collection speed of the first terminal and the second terminal according to the data to match the discharge speed of the punching machine.

[0049] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
