Description

Technical Field

[0001] The present disclosure relates to the technical field of terminal processing, and in particular to a compensable servo-driven bending device. Background Art

[0002] In modern electronics manufacturing, terminal bending technology is one of the key steps to ensure reliable connection of electronic components. Terminals serve as a bridge for transmitting electrical signals between electronic components such as circuit boards and connectors. Their precise shape directly affects the electrical performance and mechanical stability of the entire product. Terminal bending operations in related technologies mostly rely on manual operation, which is not only inefficient but also difficult to ensure the consistency and accuracy of the bending angle of each terminal, which is particularly insufficient in large-scale production environments. Furthermore, manual operation faces problems such as high labor intensity and a monotonous and repetitive working environment that lead to worker fatigue and increased risk of work-related injuries.

[0003] Terminal bending equipment in related technologies often has limitations in ensuring bending accuracy and repeatability. Whether manually operated or using less automated equipment, it is difficult to ensure consistent bending angles for each terminal in mass production, affecting the electrical connection reliability and appearance consistency of the final product. Complex bending equipment can lead to high maintenance costs and failure rates, especially when it involves precision mechanical components and electronic control systems. Once a failure occurs, the repair cycle is long, affecting production schedules. Furthermore, high equipment investment and operating costs are also factors limiting its widespread application.

[0032] Conventional terminal bending techniques rely heavily on manual labor, which is inefficient and difficult to achieve with consistent and precise bending angles for each terminal. This is particularly problematic in large-scale production environments. Furthermore, manual labor is labor-intensive and the monotonous, repetitive work environment can lead to worker fatigue and increased risk of work-related injuries.

[0033] Even with mechanical operations, terminal bending equipment in related technologies often has limitations in ensuring bending accuracy and repeatability. Furthermore, whether manually operated or with less automated equipment, it is difficult to ensure consistent bending angles for each terminal in mass production, affecting the electrical connection reliability and appearance consistency of the final product. Complex bending equipment can lead to high maintenance costs and failure rates, especially when it comes to precision mechanical components and electronic control systems. Once a failure occurs, the repair cycle is long, impacting production schedules. Furthermore, high equipment investment and operating costs are also factors limiting its widespread application.

[0034] In the disclosed embodiment, the terminal is stably supported by a support mechanism to ensure that the starting point of the processing process is accurate; the clamping mechanism not only ensures that the terminal is firmly fixed during bending, but also efficiently exposes the area to be bent, reducing manual intervention and adjustment time; the linear motion bending mechanism can complete the bending action quickly and accurately, thereby improving work efficiency.

[0035] exist Figure 1 In an example, a compensable servo-driven bending device is provided, comprising:

[0036] A supporting mechanism 200 is used to support the terminals.

[0037] A pressing mechanism 300 is arranged to move toward or away from the support mechanism 200, forming a pressing area for pressing part of the terminal between the pressing mechanism 300 and the support mechanism 200, and exposing the terminal portion 100 to be bent in a bending working area. In some embodiments, it can be up and down or in other square shapes.

[0038] A bending mechanism 400 is provided to move in a straight line so as to enter or exit the bending working area, and bends the portion to be bent 100 by entering the bending working area.

[0039] Specifically, in some embodiments, the top surface of the support mechanism 200 forms a support portion, either a flat surface or a recessed portion, for placing the terminal. The space outside the edge of the support portion forms a bending work area, exposing the portion of the terminal to be bent. For example, the support mechanism 200 can be made of a high-strength, wear-resistant material, or alternatively, a material can be selected based on actual needs to ensure stable positioning of the terminal during processing, providing an accurate starting position for subsequent bending operations and avoiding processing errors caused by inaccurate positioning.

[0040] The clamping mechanism 300 works in conjunction with the support mechanism 200, allowing it to move closer or further away from the support mechanism 200 as needed, creating a precise clamping zone. This not only ensures the terminal remains securely attached to the support mechanism 200 during the bending process, preventing displacement, but also ensures that only the portion of the terminal that needs to be bent is exposed within the bending area, significantly reducing the need for manual adjustments and improving operational reliability and efficiency.

[0041] The bending mechanism 400 is a device for realizing terminal bending, which can be driven in a straight line direction (in Figure 1 In the example, the bending mechanism 400 moves up and down along the path indicated by the arrow a, thereby entering or leaving the bending work area. Figure 1 In the example, the bending mechanism 400 moves linearly along the path indicated by the arrow a to press down the portion 100 of the terminal to be bent, thereby completing the bending operation on the portion 100 of the terminal to be bent.

[0042] The continuous operation process is as follows:

[0043] First, the terminal is accurately placed on the support mechanism 200, and then Figure 1 In this example, the clamping mechanism 300 moves along the path indicated by arrow a to approach the support mechanism 200, thereby compressing the non-bending portion of the terminal and securing the terminal in the clamping area, positioning the portion to be bent 100 within the bending area. When bending is required, the bending mechanism 400 moves linearly along path a to press downward on the portion to be bent 100, achieving a precise bend of the portion to be bent 100 through vertical or substantially vertical pressure. This linear motion ensures direct action and precise control, reducing lateral forces that may be generated during the bending process, thereby preventing deformation or damage to the terminal. In a further example, to prevent cracking during bending, the edge of the support mechanism 200 that contacts the portion to be bent 100 is arc-shaped, with an R angle of at least 80% of the terminal's bending angle. Furthermore, to prevent arching and deformation of the terminal during bending, the portion to be bent should be located on the edge of the support mechanism 200.

[0044] After the bending operation is completed, the bending mechanism 400 moves upward along the path indicated by the arrow in the straight path a, exits the bending work area, and prepares for the next terminal bending operation.

[0045] Optional, in Figure 2 In an example, the compensable servo-driven bending device may further include:

[0046] The compensation structure 500 and the support mechanism 200 are respectively located on both sides of the bending working area; the compensation structure 500 is configured to form a conflict with the bending mechanism 400 when the bending mechanism 400 moves to the bending working area, so as to apply an extrusion force toward the support mechanism 200 to the bending mechanism 400, so as to at least maintain the state of the bending part being bent toward the support mechanism 200.

[0047] Specifically, in some embodiments, the compensation structure 500 is arranged on the other side of the bending working area, forming a relative layout with the support mechanism 200, and can apply an extrusion force to limit the rebound of the terminal during the bending process, ensuring that the bending angle is accurately achieved. Figure 1 and Figure 2 When the bending mechanism 400 moves along the path indicated by arrow a into the bending working area and begins to apply a bending force to the terminal portion 100 to be bent, the bending mechanism 400 contacts the compensation structure 500, thereby applying a moderate and stable extrusion force ( Figure 2 The extrusion force F in the example). Since the terminal is elastic, a extrusion force F is applied to the terminal to prevent the terminal from rebounding after being bent by the bending mechanism 400, thereby causing the bending angle to change. The extrusion force F not only assists the bending mechanism 400 in completing the bending action of the terminal, but more importantly, it ensures that the bent portion of the terminal always maintains a stable bending state toward the support mechanism 200 during the bending process, effectively preventing the bent portion from rebounding or incomplete bending, thereby ensuring the quality and stability of the bending process.

[0048] Optional, in Figure 2 In this example, the compensation structure 500 forms a guide surface for contact with the bending mechanism 400. The guide surface is shaped to approach the support mechanism 200 as the bending mechanism 400 enters the bending work area, thereby generating the extrusion force as the bending mechanism 400 enters the bending work area. The guide surface can be an inclined surface or a curved surface, such as gradually approaching the support mechanism 200 in a downward direction as shown in the figure.

[0049] exist Figure 2In this example, the longitudinal cross-section of the compensation structure 500 may be a trapezoid, and the bending mechanism 400 and the guiding surface that contacts the bending mechanism 400 form a certain angle, so that the path of the bending mechanism 400 entering the bending working area gradually tilts toward the side of the support mechanism 200. Alternatively, the longitudinal cross-section of the compensation structure may also be a triangle, a cone, or other shapes. Figure 1 In the example, as the bending mechanism 400 gradually moves downward along the path indicated by the arrow a, thereby gradually bending the part to be bent, a force F along the bending direction can be naturally generated through the guidance of the guide surface. The inclination angle of the guide surface allows the bending mechanism 400 to feel a lateral extrusion force directed toward the bending mechanism 400 while moving forward, which not only ensures the smooth progress of the bending action, but also, through the guidance of the inclined surface, makes the bending force more concentrated and evenly act on the part to be bent 100 of the terminal, thereby improving the accuracy and efficiency of the bending.

[0050] Optional, Figure 1 or Figure 2 In the example, the bending mechanism 400 includes a rotatable bending wheel 401 for pressing the bending portion. The bending wheel 401 can not only enter the bending working area along a straight path, but also rotate as needed. Further optionally, a joint portion that matches the shape of the terminal to be bent portion 100 is provided on the outer surface of the bending wheel 401. Figure 1 In the example, the portion to be bent 100 includes a plurality of sub-portions spaced apart, and the coupling portion may include a concave-convex structure 4010 that matches the shape of the portion to be bent 100 of the terminal, and the concave-convex structure 4010 includes a groove coupled to each sub-portion, so that when bending, the portion to be bent cooperates with the concave-convex structure 4010 of the coupling portion, avoiding damage to the terminal and ensuring that the bending angles of the sub-portions are consistent, thereby improving the yield of the final product.

[0051] Optional, in Figure 2 In this example, the bending mechanism 400 includes a resisting member 402 for resisting the compensation structure 500 .

[0052] Specifically, in Figure 2 In this example, the resisting member 402 is disposed between the bending wheel 401 and the compensation structure 500 . The resisting member 402 resists the guide surface of the compensation structure 500 , thereby applying a force F toward the support mechanism 200 to the bending wheel 401 .

[0053] The working principle is as follows: when the bending mechanism 400 enters the bending working area, the resistance member 402 begins to contact the guide surface of the compensation structure 500, and as the bending mechanism 400 gradually bends the part to be bent 100 along the path indicated by the arrow a, the interaction force between the two gradually increases, so that the part to be bent of the terminal will not be incompletely bent due to elasticity.

[0054] Optional, in Figure 1 or Figure 2 In this example, it includes: a first driving mechanism 600 connected to the pressing mechanism 300 , driving the pressing mechanism 300 to move closer to or away from the supporting mechanism 200 during movement.

[0055] Specifically, in Figure 2 In the example, the first driving mechanism 600 includes a cylinder 601, one end of the gas rod 602 of the cylinder 601 penetrates into the cavity of the cylinder 601, and moves up and down in the cavity along the path indicated by the arrow a. The clamping mechanism 300 is connected to the cylinder 601 through a connecting block 603. The end of the connecting block 603 connected to the cylinder 601 is provided with a groove, the slider is fixed in the groove, and the other end is threadedly connected to the other end of the gas rod 602, thereby driving the clamping mechanism 300 to move up and down along the path indicated by the arrow a to achieve the clamping of the terminal.

[0056] Optionally, the first drive mechanism 600 can also be connected to the clamping mechanism 300 through a mechanical connection such as a rigid connection, a drive shaft, a belt, or a screw, according to actual needs, so as to achieve the purpose of driving the clamping mechanism 300 to clamp the terminal; the first drive mechanism 600 can also use an electric motor (such as a stepper motor, a servo motor 701) in conjunction with a linear motion mechanism (such as a screw), a pneumatic or hydraulic drive system, etc., and the most suitable power source can be selected according to actual application needs. Electric drive provides precise position control and speed regulation, while pneumatic or hydraulic drive shows advantages in application scenarios requiring high thrust or fast response.

[0057] Optional, in Figure 1 or Figure 2 In this example, it includes: a second driving mechanism 700, which is connected to the bending mechanism 400 and drives the bending mechanism 400 to move in a straight line into or out of the bending working area during movement.

[0058] Specifically, in some embodiments, the second drive mechanism 700 may include an electric motor (such as a servo motor 701 or a stepper motor), which is selected based on the specific requirements and environmental conditions of the bending operation. In order to achieve linear motion of the bending mechanism 400, the second drive mechanism 700 includes a linear guide 704 and a screw assembly and other transmission elements connected to the bending mechanism 400 to ensure smoothness, straightness and repeatability of the movement, and maintain consistency and stability of the movement even under long-term continuous operation. The screw assembly includes a screw 705 and a nut seat 707 that is threadedly connected to the screw.

[0059] When bending the part to be bent, the second driving mechanism 700 drives the bending mechanism 400 along the path indicated by the arrow of the straight path a, smoothly and quickly enters the bending work area, contacts the part to be bent 100 of the terminal and applies a force that enables the part to be bent to complete the bending action. After the bending is completed, the second driving mechanism 700 withdraws the bending mechanism 400 from the bending work area, returns to the initial position or prepares for the next terminal bending operation.

[0060] Optional, in Figure 2 In this example, the second driving mechanism 700 includes a servo motor 701 .

[0061] Specifically, in Figure 2 In this embodiment, the output shaft of the servo motor 701 is connected to the screw 705 via a coupling 702, ensuring smooth and coaxial power transmission and reducing vibration and wear. One end of the screw 705 is mounted in a support seat, providing necessary fixation and support to reduce runout during operation. A nut seat 707 passes through the screw 705 and moves on the screw 705. The bending mechanism 400 is connected to the linear guide 704 and the nut seat 707 via a moving mechanism 706. Specifically, the nut seat 707 and the moving mechanism 706 are fixedly connected to form an integral component. The moving mechanism 706 is slidably coupled to the linear guide 704 to restrict rotation about the screw.

[0062] The operating principle is as follows: When the servo motor 701 receives a control signal and begins operating, it transmits rotational motion to the screw 705 via the coupling 702. The motor drive base 703 securely mounts the servo motor 701, ensuring precise alignment between the servo motor 701 and the screw 705, thus maintaining system stability. As the screw 705 rotates, the integrated assembly is constrained to move along the pre-set path indicated by arrow a, allowing the bending mechanism 400 to move along the pre-set path indicated by arrow a, allowing it to precisely enter and exit the bending work area and complete the precise bending operation of the terminal.

[0063] Optionally, the first driving mechanism 600 also includes: a first sensor 604 for sensing the movement of the first driving mechanism 600 approaching the supporting mechanism 200 and outputting a first sensing signal when the first driving mechanism 600 moves to the pressing area to trigger the bending mechanism 400 to enter the bending working area to bend the part to be bent 100.

[0064] Specifically, in Figure 3 In the embodiment, combined Figure 1For example, the second driving mechanism 700 includes a cylinder 701, and the first sensor 604 includes a cylinder sensor, which is arranged on the outer surface of the cylinder 701 and is used to monitor the movement state of the cylinder. A small magnetic ring (permanent magnet) can be fixed on the gas rod 602 inside the cylinder 701. The cylinder sensor 604 (magnetic sensor, such as a reed switch) is installed on the outer wall of the cylinder 701, facing the movement path of the magnetic ring inside the gas rod 602. When the gas rod 602 with the magnetic ring moves, approaches or moves away from the sensor, the magnetic lines of force pass through the sensor housing, causing the internal reed contacts to close or open, generating an electrical signal change, which is used to represent the position information of the gas rod 602, that is, the extension or retraction state of the gas rod 602.

[0065] The first sensor can also be a non-magnetic proximity sensor (such as an inductive or capacitive sensor), which operates on a slightly different principle. For example, an inductive sensor determines position by detecting changes in the electromagnetic field caused by a metal component attached to gas rod 602 (such as a specially designed metal tag or directly using the gas rod material). When the piston approaches the sensor, the inductance of the sensor's internal coil changes, and the output signal changes accordingly. The choice of the first sensor can be determined based on actual conditions. The second sensor described below is similar to the first sensor and will not be further described in detail.

[0066] When it is detected that the clamping mechanism 300 is in place, that is, it moves to the clamping area, it will output a first sensor signal, indicating that the preparation stage of the bending operation has been completed. The output of the first sensor signal serves as a signal to trigger the bending mechanism 400 to enter the bending working area. Once the clamping mechanism 300 is ready, without manual intervention, the bending mechanism 400 will automatically start, enter the bending working area in a straight line, and begin to accurately bend the part to be bent 100 of the terminal. This not only ensures that the timing of the bending operation is just right, avoiding the processing quality problems that may be caused by early or late action, but also significantly improves production efficiency and reduces time loss caused by human judgment and operation delays.

[0067] Optionally, the first driving mechanism 600 further includes: a second sensor 605 for sensing when the first driving mechanism 600 is away from the supporting mechanism 200 and outputting a second sensing signal.

[0068] Specifically, in Figure 3 In an embodiment, the first driving mechanism 600 drives the clamping mechanism 300 to start moving away from the supporting mechanism 200, and the second sensor 605 responds by outputting a second sensing signal, indicating the end of the clamping process. For example, it may instruct the bending mechanism 400 to exit the bending area after completing the bending, or notify the supporting mechanism 200 and / or the clamping mechanism 300 to prepare for the next round of terminal loading and clamping, or notify the outside to prepare to place the next terminal to be bent.

[0069] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
