Description

Technical Field

[0001] This application relates to the field of connector crimping technology, and more specifically, to a semi-automatic connector crimping machine. Background Technology

[0002] Connector crimping is a crucial electronic assembly process. Its core lies in applying immense pressure to the connector terminals using precision molds, causing permanent plastic deformation and thus achieving a secure electrical connection and mechanical fixation with the wires. This process demands micron-level precision and absolute consistency; any deviation can lead to signal transmission failure. Its technical complexity and precision are comparable to minimally invasive surgery.

[0003] Completing a successful crimping is far from a single action; it involves a rigorous sequence of procedures. It begins with the precise loading and unloading of the connector, followed by accurate positioning. After the stripped cable is inserted into the corresponding pins, the core crimping action is performed by the mold. Finally, the pin frame is cut and the finished product is unloaded. These steps must be seamlessly coordinated in terms of timing, space, and force, and the complexity of this system constitutes a fundamental challenge in equipment design.

[0004] To meet the streamlined operation requirements of the aforementioned complex processes, traditional crimping machines generally adopt a linear assembly line layout, where modules for feeding, conveying, cutting, crimping, and unloading are arranged sequentially in a straight line. While this layout is logically clear, it directly results in a lengthy machine body, presenting significant drawbacks: on the one hand, it occupies a large amount of valuable factory floor space, increasing the space cost of the production line; on the other hand, the excessive length makes it difficult to guarantee the rigidity of the equipment, and long-distance conveying also increases positioning errors and cycle time. More importantly, this "long, straight line" structure severely restricts the flexible deployment and convenient transportation of the equipment in modern, compact workshops. Summary of the Invention

[0005] To address the shortcomings of the existing technology, the purpose of this application is to provide a semi-automatic connector crimping machine that shortens the connection length of the semi-automatic connector crimping machine, reduces the length ratio of the equipment, and provides greater convenience for the transportation and placement of the equipment.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a semi-automatic connector crimping machine, comprising: Base; A workbench is mounted on the base; A connector feeding mechanism, mounted on the workbench, is used to output multiple connectors one by one; A cutting mechanism, disposed on the workbench and located downstream of the connector feeding mechanism, is used to cut the pins of the connector; A crimping mechanism, disposed on the workbench and located downstream of the cutting mechanism, is used to crimp and fix the connector and the connecting wire. A pushing mechanism, disposed on the workbench, is used to push a single connector sequentially toward the cutting mechanism and the crimping mechanism; A conversion mechanism is disposed between the connector feeding mechanism and the pushing mechanism, and is used to transfer the connector from the feeding mechanism to the pushing mechanism; The connector feeding mechanism is located to the side of the pushing mechanism, and the cutting mechanism and the crimping mechanism are arranged sequentially along the pushing direction of the pushing mechanism.

[0007] Preferably, the connector feeding mechanism includes: A blanking plate, used to hold multiple connectors; A material discharge chute, formed on the material discharge plate, is used to accommodate and guide the movement of the connector; The first driving component is connected to the blanking plate and is used to drive the blanking plate to move vertically; A transfer component, disposed at one end of the discharge plate, is used to push the connector in the discharge trough toward the conversion mechanism; The end of the material feeding chute furthest from the transfer component is connected to the conversion mechanism, which is used to feed the connectors one by one into the conversion mechanism.

[0008] Preferably, the transfer assembly includes: An air blowing channel is provided at the end of the material discharge plate and communicates with the material discharge chute; An air blowing device is connected to the air blowing channel; An airflow control valve, connected to the blowing device, is used to switch the airflow direction; The air blowing device has a first working mode and a second working mode; In the first working mode, the airflow control valve directs the airflow towards the material drop chute, blowing the connector to the conversion mechanism; In the second operating mode, the airflow control valve directs the airflow to the conversion mechanism.

[0009] Preferably, the cutting mechanism includes: A cutter, which can be raised and lowered relative to the worktable, is used to cut the side pins of the connector; The second drive component is connected to the cutter and is used to drive the cutter to move up and down. When the second driving component drives the cutter to move downward, it cuts the connector side pins located at the cutting station.

[0010] Preferably, the crimping mechanism includes: The pressure cutter can be raised and lowered relative to the worktable and is used to press and fix the metal sheet to the connecting wire; The third drive component is connected to the pressure knife and is used to drive the pressure knife to move up and down. When the third driving component drives the pressing knife to move downward, it applies pressure to the connector located at the crimping station, so that the metal sheet and the connecting wire form a crimped connection.

[0011] Preferably, the pushing mechanism includes: A limiting groove is provided on the worktable to accommodate and guide the movement of the connector; A push plate is movably disposed within the limiting groove for pushing the connector; The fourth drive component, connected to the push plate, is used to drive the push plate to move horizontally and vertically within the limiting groove; When the fourth driving component drives the push plate to move, it causes the connector to pass through the cutting station and the crimping station in sequence.

[0012] Preferably, the conversion mechanism includes: A receiving slot is used to accommodate a single connector; The fifth drive component, connected to the receiving groove, is used to drive the receiving groove to reciprocate between the connector feeding mechanism and the pushing mechanism; The sixth drive component, disposed on the worktable and located at one end near the push mechanism, is used to push the connector in the receiving slot to the push mechanism; The receiving groove moves under the drive of the fifth driving component to a position to dock with the connector feeding mechanism to receive the connector, and then moves to a position to dock with the pushing mechanism, whereby the sixth driving component pushes the connector into the pushing mechanism.

[0013] Preferably, the connector feeding mechanism operates by the first driving component driving the blanking plate to move vertically, so that the blanking groove docks with the conversion mechanism; The transfer component pushes the connector in the discharge trough toward the conversion mechanism; After each connector is delivered, the feeding plate is driven by the first driving component to rise or fall a distance equal to the thickness of one connector, so that the next connector is aligned with the conversion mechanism. Repeat the above steps to continuously feed the connectors one by one.

[0014] Preferably, the conversion mechanism is driven by the fifth drive component to move the receiving groove to a position where it aligns with the output end of the connector feeding mechanism; The connector feeding mechanism feeds a single connector into the receiving slot; The fifth drive component drives the receiving slot to move the connector to a position where it docks with the input end of the pushing mechanism; The sixth drive component is activated to push the connector in the receiving slot into the pushing mechanism; The fifth drive component drives the unloaded receiving slot back to the position where it docks with the connector feeding mechanism, waiting for the next feeding.

[0015] Preferably, the bottom of the receiving groove of the conversion mechanism is provided with at least one through hole; The through hole is connected to the second output end of the airflow control valve; When the airflow control valve switches to the second working mode, the airflow is blown into the receiving groove through the through hole to remove the residue.

[0016] In summary, the beneficial effects of this application are as follows: The connector feeding mechanism sequentially transports individual connectors to the conversion mechanism, which then transfers them to the pushing mechanism. The pushing mechanism then passes the connectors through a cutting mechanism and a crimping mechanism, completing the cutting of the connector pins and the crimping of the connector with the connecting wire. Since the entire connector operation process is relatively long, the conversion mechanism acts as a bridge between the connector feeding mechanism and the pushing mechanism. Furthermore, the connector feeding mechanism is positioned to the side of the pushing mechanism, thereby shortening the connection length of the semi-automatic connector crimping machine, reducing the overall length of the equipment, and providing greater convenience for transportation and placement.

Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] The semi-automatic connector crimping machine of the present invention, such as Figures 1-7 As shown, it includes a base 1 and a worktable 11 fixedly mounted on the base 1. The worktable 11 adopts an integrated cast iron structure with an internal reinforcing rib network to improve the overall bending stiffness. The worktable 11 integrates a connector feeding mechanism 2, a cutting mechanism 3, a crimping mechanism 4, a pushing mechanism 5, and a conversion mechanism 6.

[0024] The connector feeding mechanism 2 is located to the side of the pushing mechanism 5, and the cutting mechanism 3 and the crimping mechanism 4 are arranged sequentially along the pushing direction. The conversion mechanism 6 is located between the connector feeding mechanism 2 and the pushing mechanism 5, and is used to transfer the connector from the feeding mechanism to the pushing mechanism. This non-linear compact layout reduces the equipment length by more than 30% compared to the traditional linear layout.

[0025] like Figure 2 As shown, the connector loading mechanism 2 includes a dropping plate 21, dropping slots 22, a first drive assembly 23, and a transfer assembly 24. The dropping plate 21 is a rectangular flat plate structure, horizontally mounted above the worktable 11, and has multiple parallel dropping slots 22 inside, each of which is used to accommodate multiple connectors. The first drive assembly 23 is a linear servo motor connected to the dropping plate 21, used to drive the dropping plate 21 to move vertically, thereby switching between different dropping slots 22.

[0026] The transfer assembly 24 is disposed at one end of the discharge plate 21 and includes an air blowing channel 241 (not shown in the figure), an air blowing device 242 (not shown in the figure), and an airflow control valve 243 (not shown in the figure). The air blowing channel 241 (not shown in the figure) is disposed at the end of the discharge plate 21 and communicates with the discharge chute 22. The air blowing device 242 (not shown in the figure) is connected to the air blowing channel 241 (not shown in the figure). The airflow control valve 243 (not shown in the figure) is used to switch the airflow direction and has a first output end and a second output end.

[0027] like Figure 2 As shown, the conversion mechanism 6 includes a receiving groove 61, a fifth drive assembly 62, and a sixth drive assembly 63. The receiving groove 61 is an elongated groove-shaped structure with its opening facing upwards, used to receive a single connector. Multiple through holes 611 (not shown in the figure) are provided at the bottom of the receiving groove 61; in this embodiment, three are provided, evenly distributed along the length of the receiving groove 61, with a diameter of 2-3 mm.

[0028] The fifth drive assembly 62 is a ball screw linear module connected to the receiving groove 61, used to drive the receiving groove 61 to reciprocate between the connector loading mechanism 2 and the pushing mechanism 5. The sixth drive assembly 63 is a miniature cylinder, set on the worktable 11 and located at one end near the pushing mechanism 5, with a push rod at its output end, used to push the connector in the receiving groove 61 into the pushing mechanism 5.

[0029] Below the receiving groove 61 is a gas collecting chamber, which is a closed cavity fixedly installed directly below the receiving groove 61 and sealed to the bottom outer wall of the receiving groove 61. The top opening of the gas collecting chamber communicates with the through hole 611 of the receiving groove 61, and the side wall of the gas collecting chamber is provided with an air inlet, which is connected to the second output end of the airflow control valve 243 through a flexible air pipe.

[0030] First mode of feeding and pushing: When the receiving slot 61 moves under the drive of the fifth drive component 62 to directly below the dropping plate 21 and aligns with the outlet of the dropping slot 22, the airflow control valve 243 (not shown in the figure) switches to the first working position, directing the airflow to the blowing channel 241 (not shown in the figure). Compressed air enters the dropping slot 22 through the blowing channel 241 (not shown in the figure), pushing the connector located at the end of the dropping slot 22 to slide smoothly out along the direction of the dropping slot 22 and fall into the receiving slot 61 below. The blowing duration is preset to 0.3-0.5 seconds according to the connector specifications to ensure that the connector is completely inserted into the receiving slot 61 without flipping over.

[0031] Second self-cleaning mode: When the receiving tank 61 completes the connector transfer task (i.e., after the sixth drive component 63 pushes the connector into the pushing mechanism 5), the receiving tank 61 is in an unloaded state. During the process of the fifth drive component 62 driving the receiving tank 61 back to the loading position, or during the interval waiting for the next loading after returning, the airflow control valve 243 switches to the second working position, directing the airflow to the cleaning pipeline. Compressed air enters the air collection chamber through the cleaning pipeline, accumulates and is evenly distributed in the air collection chamber, and then is injected from bottom to top into the receiving tank 61 through multiple through holes 611 at the bottom of the receiving tank 61, forming a vortex or turbulence, blowing away the tiny dust, debris or oil particles attached to the inner wall and bottom of the receiving tank 61, and escaping from the upper opening of the receiving tank 61 with the airflow. The cleaning blowing duration is set to 0.5-1.0 seconds.

[0032] The third mode of self-calibration: When the receiving slot 61 moves under the drive of the fifth drive component 62 to directly below the dropping plate 21 and aligns with the outlet of the dropping slot 22, the airflow control valve 243 (not shown in the figure) switches to the first working position, directing the airflow to the blowing channel 241 (not shown in the figure). Compressed air enters the dropping slot 22 through the blowing channel 241 (not shown in the figure), pushing the connector located at the end of the dropping slot 22 to slide smoothly out along the direction of the dropping slot 22 and fall into the receiving slot 61 below. However, if the connector is found to be misaligned in the receiving slot 61, the airflow control valve 243 switches to the second working position, directing the airflow to the cleaning pipeline. The blowing time interval ensures that the connector enters the receiving slot 61 completely and accurately, thus performing self-calibration. The connector's dropping position calibration can be performed by a detector in the dropping slot or by visual observation.

[0033] like Figure 3 As shown, the pushing mechanism 5 includes a limiting groove 51, a pushing plate 52, and a fourth driving assembly 53. The limiting groove 51 is formed on the surface of the worktable 11 and extends horizontally. Its cross-sectional shape matches the bottom contour of the connector, and it is used to laterally constrain the connector and guide it to move along a predetermined path. The limiting groove 51 is equipped with photoelectric sensors at the cutting station and the crimping station, respectively, to detect whether the connector is accurately positioned.

[0034] The push plate 52 is an L-shaped metal component, with its vertical section inserted into the limiting groove 51 and contacting the tail of the connector, and its horizontal section extending below the worktable 11. The fourth drive assembly 53 is a two-degree-of-freedom actuator, including a lifting unit and a translation unit, used to drive the push plate 52 to move horizontally and vertically within the limiting groove 51.

[0035] In the work cycle, the fourth drive component 53 first drives the push plate 52 to rise into the limiting groove 51, so that it fits against the tail of the inserted connector; then the translation unit starts, driving the push plate 52 and the connector to move synchronously to the cutting station; after the cutting is completed, the push plate 52 continues to push the connector to the crimping station; after the crimping is completed, the push plate 52 pushes the finished connector to the unloading area, and then resets.

[0036] The cutting mechanism 3 includes a cutter 31 and a second drive assembly 32. The cutter 31 is a high-hardness alloy steel blade mounted on a vertically movable slider, used to cut the side pins of the connector. The second drive assembly 32 is a linear servo driver connected to the cutter 31, used to drive the cutter 31 to move up and down. After the connector is pushed to the cutting station and positioned, the second drive assembly 32 drives the cutter 31 to move downward, cutting into the root of the side pins of the connector, completing the precise removal of excess pins. The cutting depth is controlled by the closed-loop position of the servo driver, with a set value of 0.8 mm and a repeatability of ±0.01 mm.

[0037] The crimping mechanism 4 includes a crimping die 41 and a third drive assembly 42. The crimping die 41 is a customized stamping die mounted on a vertical guide post. Its lower die surface is geometrically matched with the connector terminal cavity, and its upper die surface has a V-groove for accommodating the wire. The third drive assembly 42 is a high-response electric servo press connected to the crimping die 41 and used to drive the crimping die 41 to move up and down. When the connector and the manually pre-placed wire are pushed to the crimping station and aligned, the third drive assembly 42 applies a set pressure downwards, driving the crimping die 41 to close, forcing the metal terminal to undergo plastic deformation, wrapping and securing the wire, forming an electrical connection. The crimping force is set to 1500 Newtons, and the holding time is 0.5 seconds.

[0038] The first drive component 23, the second drive component 32, the third drive component 42, the fourth drive component 53, the fifth drive component 62, and the sixth drive component 63 are all uniformly scheduled by the same central coordinating controller. The central coordinating controller is a PLC-based industrial control system. Each drive component communicates with the central coordinating controller through an industrial bus to provide real-time feedback of position, speed, and status information, forming a closed-loop control circuit.

[0039] The process flow of the central collaborative controller includes seven stages: initialization, loading, transfer, cutting, pressing, unloading, and reset. Each stage has interlocking conditions: the loading mechanism is only allowed to perform the next separation action when the pushing mechanism 5 is in the starting position and the conversion mechanism 6 is idle; the cutting command is only triggered after the photoelectric sensor at the cutting station confirms that the position is in place.

[0040] Both the pressure cutter 41 and the cutter 31 are equipped with quick-change interfaces. The interface adopts a combination of dovetail groove and wedge locking mechanism. After the pressure cutter 41 or the cutter 31 slides into the dovetail groove, it is locked by the pneumatic wedge block. The replacement time is no more than 30 seconds, which facilitates mold switching for different models of connectors.

[0041] In this solution, "semi-automatic" means that the connecting wire needs to be manually inserted into the connector terminal, while the remaining processes such as connector loading, transfer, cutting, crimping, unloading, and self-cleaning are all completed automatically. The manual operation station is located in front of the crimping station. The operator inserts the stripped connecting wire into the positioned connector, and then the crimping mechanism automatically completes the crimping.

[0042] In summary, the semi-automatic connector crimping machine of this invention, through engineered structural design, precise motion control, and rigorous timing coordination, achieves miniaturization, high rigidity, and high efficiency while ensuring crimping accuracy and process integrity. Its technical solution is fully disclosed, with clear descriptions of component selection, installation methods, control logic, and process parameters. Those skilled in the art can implement this invention without creative effort based on this specific embodiment.
