The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Such as Figures 1 to 8The terminal crimping device shown includes: a conveying mechanism 1, a crimping machine 2, and a clamping mechanism 3. The conveying mechanism 1 is movably connected to a terminal carrier 11. The terminal carrier 11 is used to place the terminals to be processed, and the terminal carrier 11 is configured to move within the stroke of the conveying mechanism 1; the crimping machine 2 is arranged at one end of the stroke of the conveying mechanism 1 and is used to crimp the terminals to be processed; the clamping mechanism 3 is arranged on one side of the crimping machine 2 and is used to clamp the wire harness to be processed; wherein, when the terminal carrier 11 moves to the crimping machine 2, the clamping mechanism 3 clamps the wire harness to be processed and inserts it into the terminal to be processed, and the crimping machine 2 performs crimping. As Figure 1 and Figure 2 shown, the conveying mechanism 1 is used to drive and guide the terminal carrier 11 to move along a set path. Through the reciprocating stroke of the conveying mechanism 1, the terminal carrier 11 can move from the feeding station to the crimping station, realizing the transportation of the terminals to be processed. The terminal carrier 11 is movably connected to the conveying mechanism 1 and is used to place the terminals to be processed. The terminal carrier 11 moves to the crimping station under the drive of the conveying mechanism 1. The crimping machine 2 is arranged at one end of the stroke of the conveying mechanism 1. After the terminals and the wire harness are accurately butted, the crimping machine 2 will perform a crimping action to firmly connect the terminals and the wire harness. The clamping mechanism 3 is arranged on one side of the crimping machine 2 and is used to clamp the wire harness to be processed. After the terminal carrier 11 is in place, it accurately controls the position of the wire harness, so that the wire harness is inserted into the terminal, preparing for the action of the crimping machine 2, thereby realizing automatic collaborative operation. When the terminal carrier 11 moves to the position of the crimping machine 2, the clamping mechanism 3 synchronously clamps the wire harness and inserts it into the terminal, and then the crimping machine 2 starts the crimping action to complete the automated connection process of the wire harness and the terminal.

[0024] In the above embodiment, the present invention conveys the terminals to be processed to the crimping machine 2 through the conveying mechanism 1, and the clamping mechanism 3 inserts the wire harness to be processed into the terminals to be processed. Subsequently, the crimping machine 2 performs a crimping action. Compared with the prior art, it avoids the high dependence on manual operation in the traditional process, realizes the automation of the terminal crimping process, and improves the production efficiency of the terminal crimping operation.

[0025] In the embodiment of the present invention, the specific structure of the conveying mechanism 1 is as Figure 3As shown, the conveying mechanism 1 further includes a base 12, a first drive 13, and a lead screw 14; the lead screw 14 is rotatably installed on the base 12, and the terminal carrier 11 is installed on the lead screw 14; the first drive 13 is installed on the base 12 to drive the lead screw 14 to rotate, so that the terminal carrier 11 moves linearly along the lead screw 14. The base 12 is the support foundation of the conveying mechanism 1, used to fix and carry the lead screw 14 and the first drive 13 device, ensuring the stability of the entire structure. The lead screw 14 is a long strip-shaped rotating member, and its two ends are rotatably installed on the base 12, used as the moving guide rail of the terminal carrier 11, and the terminal carrier 11 realizes its linear displacement in the axial direction as the lead screw 14 rotates. The first drive 13 is installed on the base 12 to drive the lead screw 14 to rotate. It should be noted here that there are various ways for the first drive 13 to drive the lead screw 14 to rotate. It can be a synchronous belt drive method. A pulley is provided on the output shaft of the first drive 13 and is connected to the pulley at one end of the lead screw 14 through a synchronous belt to form a synchronous drive. It can also adopt a gear drive or a coupling connection method, etc. The specific selection method can be selected according to actual usage requirements. In this embodiment, the conveying mechanism 1 can accurately control the position movement of the terminal carrier 11 inside the equipment, realizing the automatic action of conveying the terminal from the initial position to the crimping station, which helps to improve the reliability of the subsequent crimping process.

[0026] Further, a connecting block 141 is movably sleeved on the lead screw 14, the terminal carrier 11 is fixed on the connecting block 141, and a slide rail 121 adapted to the terminal carrier 11 is provided on the base 12. As Figure 3 shown, a connecting block 141 is movably sleeved on the lead screw 14, used to convert the rotational motion of the lead screw 14 into the linear movement of the terminal carrier 11. The terminal carrier 11 is fixedly arranged on the connecting block 141 and can be connected to the connecting block 141 through positioning structures such as screwing and pin insertion. Thus, while the lead screw 14 drives the connecting block 141 to move, the synchronous movement of the terminal carrier 11 is realized. In addition, in order to prevent the terminal carrier 11 from shaking or deflecting during the movement process and improve the stability and accuracy of the movement, a slide rail 121 adapted to the terminal carrier 11 is provided on the base 12, and the terminal carrier 11 is provided with a matching slider structure and can move smoothly on the slide rail 121. In this embodiment, through the coordinated cooperation of the lead screw 14, the connecting block 141, and the slide rail 121, the high-precision linear conveyance of the terminal carrier 11 is realized, improving the reliability of the equipment operation and the accuracy of the crimping station positioning.

[0027] Further, in order to avoid hard friction between the base 12 and the terminal carrier 11, a plurality of rollers 122 are also provided on the base 12, and the rollers 122 are in rolling contact with the lower bottom surface of the terminal carrier 11. As Figure 3As shown, the roller 122 is a plurality of rotation support members arranged at intervals. When the terminal carrier 11 moves along the slide rail 121 driven by the lead screw 14, its bottom contacts the roller 122. Under the support of the roller 122, the terminal carrier 11 can achieve smooth sliding with relatively small frictional force. In this embodiment, the rolling friction is much smaller than the sliding friction, which helps to reduce the driving load of the lead screw 14 and improve the transmission efficiency. It not only optimizes the motion support mode of the terminal carrier 11, but also further improves the operation stability and service life of the equipment.

[0028] In the embodiment of the present invention, in order to ensure the placement state of the terminals to be processed, a pre-pressing mechanism 4 is further provided on the stroke path at one end of the conveying mechanism 1 away from the press 2. The pre-pressing mechanism 4 includes a positioning press block 41 and a second drive 42. The second drive 42 causes the positioning press block 41 to press and position the terminals to be processed. As Figure 3 and Figure 4 shown, the positioning press block 41 is a component that performs the pressing action. Its position is arranged opposite to the terminal placement area on the terminal carrier 11. Its shape can be customized according to the shape of the terminals, and is used to fit and press the terminals. The second drive 42 is used to drive the positioning press block 41 to move in the vertical direction to complete the pressing and positioning operation of the terminals to be processed. It should be understood here that the second drive 42 can be a linear drive mechanism such as an electric push rod, a cylinder or a small motor. Among them, a monitoring sensor can also be added to monitor whether the terminal carrier 11 is correctly aligned with the pre-pressing mechanism 4. When the terminal carrier 11 moves to the position where the pre-pressing mechanism 4 is located, the second drive 42 drives the positioning press block 41 to act, applying a vertical pressing force to the terminals, so that the terminals are effectively fixed before entering the crimping area, avoiding alignment errors caused by terminal shaking or unstable assembly.

[0029] In the embodiment of the present invention, a forming module 21 is provided on the press 2. The forming module 21 is adapted to the terminal carrier 11 to form the terminals to be processed. As Figure 5As shown, the forming module 21 is used to perform shaping and crimping operations on the terminals to be processed. Its structure and size are designed to be adapted to the terminal carrier 11, ensuring that the terminals to be processed can achieve high-quality crimping and forming on the basis of accurate positioning. The forming module 21 usually includes an upper die and a lower die. The terminals to be processed are placed on the lower die, and the upper die is arranged on the crimping machine 2. The forming surface of the die is customized according to the shape of the terminals to be processed, and can form a crimping profile that meets the specifications during the crimping process. After the terminal carrier 11 moves to the position of the crimping machine 2, the terminals to be processed carried thereon are accurately aligned with the forming module 21 through the terminal carrier 11. Subsequently, under the drive of the crimping machine 2, the forming module 21 applies pressure to the terminals, making them firmly combined with the wire harness conductors and forming a stable crimping structure. Among them, a monitoring sensor can also be set at the crimping machine 2 to detect whether the crimping machine 2 is aligned with the terminal carrier 11. In this embodiment, the consistency and qualification rate of the crimping and forming are improved, which is beneficial to the realization of the automation of the crimping process.

[0030] In the embodiment of the present invention, the specific structure of the clamping mechanism 3 is as Figure 6 shown. The clamping mechanism 3 includes a wire harness jaw 31, a lateral drive 32, and a vertical drive 33; the wire harness jaw 31 clamps the wire harness to be processed; the lateral drive 32 is connected to the vertical drive 33, and the wire harness jaw 31 is installed on the lateral drive 32, so that the wire harness jaw 31 makes a combined movement of approaching or moving away from the crimping machine 2. The wire harness jaw 31 is a clamping execution component, which can be set as a pair of relatively opening and closing fingers or V-shaped clamping blocks, and can firmly clamp the wire harness outer skin without damaging the conductor. The opening and closing mode of the wire harness jaw 31 can be pneumatic, electric, or spring return structure to achieve rapid response and stable clamping. The lateral drive 32 is used to drive the wire harness jaw 31 to move horizontally, so that the wire harness approaches or moves away from the crimping machine 2. This drive mechanism can adopt a slide table, an electric push rod, or a linear motor structure. The vertical drive 33 is used to drive the lateral drive 32 assembly and the clamping jaw as a whole to lift and lower in the vertical direction, facilitating the up and down movement of the wire harness jaw 31 and realizing the coordinated movement between different heights or different workstations. The lateral drive 32 is installed on the vertical drive 33, and the wire harness jaw 31 is installed on the lateral drive 32, thus constituting a clamping structure with the ability of combined movement, that is, the wire harness jaw 31 realizes the horizontal movement of approaching or moving away from the crimping machine 2 and the up and down position adjustment under the cooperation of the lateral drive 32 and the vertical drive 33, so as to complete a series of actions such as clamping, moving, positioning, and inserting of the wire harness. In this embodiment, the setting of the clamping mechanism 3 further improves the automation degree of the terminal crimping equipment.

[0031] In the above clamping mechanism 3, to prevent the wire harness from adhering to the forming module 21 after crimping, a pressing arm can be added to the clamping mechanism 3. The pressing arm abuts against the wire harness to provide a downward pressure, enabling it to break away from the adhesion state with the forming module 21. Additionally, to prevent the wire harness from sagging due to excessive length, a supporting tray can be provided. The supporting tray is configured to support the middle part of the sagging wire harness, ensuring a unified state of the wire harness throughout the processing.

[0032] In an embodiment of the present invention, a flexible vibration mechanism 5 is further provided, including a flexible vibrating disk 51, a vibration isolation plate 52, a terminal storage bin 53, a terminal gripper 54, and a detection camera 55. The vibration isolation plate 52 is fixed below the flexible vibrating disk 51. The terminal storage bin 53 is arranged obliquely above one side of the flexible vibrating disk 51. The terminal gripper 54 is arranged obliquely above the other side of the flexible vibrating disk 51. The detection camera 55 is installed directly above the flexible vibrating disk 51. As Figure 7 shown, the flexible vibrating disk 51 is used to carry and orderly vibrate and arrange the scattered terminals. This vibrating disk can screen the terminals to be processed by finely adjusting the vibration frequency and amplitude at high speed in cooperation with the detection camera 55. The vibration isolation plate 52 is fixedly arranged below the flexible vibrating disk 51 to block the vibration from being transmitted to the base 12, reducing the overall vibration interference of the equipment and enhancing the working stability. The terminal storage bin 53 is arranged obliquely above one side of the flexible vibrating disk 51 and is used to store the terminals to be processed. It has an inclined structure, facilitating the smooth sliding of the terminals onto the vibrating disk, which helps improve the feeding efficiency and continuity. The terminal gripper 54 is arranged obliquely above the other side of the flexible vibrating disk 51 and can be composed of an end effector of a robotic arm. Under the guidance of the detection camera 55 and the positioning signal, it accurately picks up the terminals in a qualified posture from the flexible vibrating disk 51 and transfers them to the subsequent process. The detection camera 55 is installed directly above the flexible vibrating disk 51 and is used to collect the images of the terminals on the vibrating disk in real time. Through the supporting visual recognition algorithm, the system can identify the position, posture, and quantity of the terminals, guide the terminal gripper 54 to perform the grasping operation, and rearrange the posture of the terminals that do not meet the requirements by vibration. In this embodiment, the flexible vibration mechanism 5 can adapt to various different specifications of terminals. In cooperation with the detection camera 55 and the automated robotic arm, it realizes intelligent feeding, automatic sorting, and precise positioning, improving the automation efficiency of the terminal crimping equipment.

[0033] In an embodiment of the present invention, to perform secondary adjustment and positioning on the terminals clamped by the terminal gripper 54, an adjustment mechanism 6 is further provided, including an adjustment gripper 61 and a third drive 62. The adjustment mechanism 6 is arranged on the side of the conveying mechanism 1 away from the crimping machine 2. The third drive 62 enables the adjustment gripper 61 to adjust the clamping angle. As Figure 8As shown, the adjusting jaw 61 is used to clamp and adjust the posture of the terminal to be processed, and can change the clamping angle of the terminal by means of rotation, tilting, etc. This jaw can be designed as a multi-finger type or a customized clamping end according to the shape of the terminal to meet the stable clamping requirements of different terminal shapes. The third drive 62 provides the power source for the adjusting jaw 61 and is used to realize the opening and closing and angle adjustment actions of the jaw. The third drive 62 can be a stepper motor, a servo motor or a pneumatic rotary drive device with an encoder to achieve precise control and repeated positioning of the jaw angle. During the actual working process, after the terminal to be processed is fed by the flexible vibration mechanism 5, it is picked up by the terminal jaw 54 and transferred to the adjusting mechanism 6; at this time, the third drive 62 drives the adjusting jaw 61 to clamp and rotate for posture adjustment according to the preset angle to ensure that the terminal is in a standard posture suitable for subsequent wire harness insertion or crimping. After the posture adjustment is completed, the terminal is sent into the terminal carrier 11 and then enters the crimping station to perform the formal crimping operation. In this embodiment, problems such as difficult insertion or offset crimping caused by inconsistent terminal postures are avoided, and the stability and consistency of the crimping process are improved.

[0034] In an embodiment of the present invention, a crimping method for the above terminal crimping equipment is also provided, specifically as Figure 9 shown. Since this crimping method has been introduced in detail above, it will not be elaborated here. Those skilled in the art can refer to the above for understanding, including the following steps: S10: Place the terminal to be processed into the terminal storage bin and place the wire harness to be processed into the wire harness jaw; S20: Start the flexible vibrating disk, and the inspection camera identifies and judges the terminal to be processed after vibration. Clamp the terminal to be processed with a qualified state after vibration by the terminal jaw and place it on the adjusting jaw; S30: Start the adjusting motor, and the adjusting jaw adjusts the angle of the terminal to be processed; S40: After the adjustment is completed, the terminal to be processed is placed on the terminal carrier by the terminal jaw; S50: Start the pre-crimping mechanism, and the positioning press block presses and positions the terminal to be processed; S60: Start the conveying mechanism, and convey the terminal carrier carrying the terminal to be processed to directly below the crimping machine; S70: Start the clamping mechanism, and the wire harness jaw sends the wire harness to be processed to the crimping machine so that the terminal to be processed is sleeved on the end of the wire harness to be processed; S80: Start the crimping machine, and the forming module crimps and forms the wire harness to be processed and the terminal to be processed; S90: After the forming is completed, the crimping machine resets, the conveying mechanism continues to convey a certain distance along the original movement direction, and the clamping mechanism takes out the wire harness and resets; S100: Reset the conveying mechanism and perform the next cycle.
