[0012] Furthermore, this application also proposes that the position adjustment assembly includes an X-axis drive unit, a Y-axis drive unit, and a Z-axis drive unit, with the X-axis drive unit mounted on the mounting frame, the Y-axis drive unit mounted on the X-axis drive unit, the Z-axis drive unit mounted on the Y-axis drive unit, and the rotation assembly mounted on the Z-axis drive unit.

Detailed Implementation
[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] In traditional component loading processes, the manual handling and placement of components, which require the insertion of different types or specifications of components into circuit boards, often results in inconsistent pin orientations. Furthermore, manual intervention cannot guarantee that the pins of the components will always face downwards. This not only reduces insertion accuracy but also increases uncertainty in the production process, making it difficult for the system to adapt to the rapid switching requirements of multiple component specifications, thus affecting the continuity and stability of the overall production flow.
[0023] For example, in electronic manufacturing production lines processing circuit boards containing various through-hole components such as resistors, capacitors, and integrated circuits, operators must manually remove the components from storage containers and individually adjust their orientation so that the leads are facing down when placed in the designated position on the loading device. Furthermore, in this scenario, due to significant differences in the size and shape of the components, bent or incorrectly oriented leads often occur, causing the insertion machine's gripper head to fail to accurately grasp the components, leading to production line stoppages and increased manual reset operations. Therefore, the unreliability of manual operation directly manifests as interruptions in the insertion process and a decrease in equipment operating efficiency.
[0024] If the above problems are not addressed, the reliability of the insertion process will be significantly reduced. Incorrect pin orientation of the insert material may cause physical damage to the conductive vias of the circuit board, increasing the product defect rate. In addition, frequent manual intervention will prolong the production cycle, reduce the overall operating efficiency of the equipment, and have a continuous negative impact on large-scale production, making it difficult for the system to meet the requirements of high-precision and high-efficiency production.
[0025] For this, please refer to Figure 1 This application proposes a plug-in feeding device 100 for feeding plug-in materials, including a mounting frame 110, a flexible vibrating tray 120, an identification mechanism 130, a correction mechanism 140, and a gripping mechanism 150. The flexible vibrating tray 120, the identification mechanism 130, the correction mechanism 140, and the gripping mechanism 150 are all mounted on the mounting frame 110. The flexible vibrating tray 120 is used to place and vibrate the plug-in materials. The identification mechanism 130 is used to identify the plug-in materials to be fed in the flexible vibrating tray 120. The gripping mechanism 150 can grip the plug-in materials to be fed according to the identification information of the plug-in materials obtained by the identification mechanism 130, rotate around an axis extending in the vertical direction, and transfer the plug-in materials to be fed to the correction mechanism 140. The correction mechanism 140 can correct the plug-in materials to be fed so that the pins of the plug-in materials face downwards according to the identification information of the plug-in materials obtained by the identification mechanism 130.
[0026] In existing technologies, the component loading process relies on manual intervention to organize and place components of different types or specifications, resulting in limited operational efficiency and a high risk of orientation errors. This application proposes a component loading device 100, designed to automate the loading of component materials and ensure that the pins are facing downwards. A flexible vibrating tray 120 is used to place and vibrate the component materials. This can be achieved using a spring-supported structure in conjunction with an electromagnetic vibrator. For example, the vibration frequency can be adjusted to arrange the component materials in an orderly manner within the tray 121, or an eccentric wheel mechanism can be used to generate directional vibration to reduce component material stacking.
[0027] The identification mechanism 130 is used to acquire the position and orientation information of the plug-in material to be loaded in the flexible vibrating feeder 120. In practical applications, the mechanism can collect information by manually inputting the plug-in material parameters. For example, the operator can input the plug-in material type and initial coordinates through the control interface, or use an infrared sensor array to detect the outline features of the plug-in material. Its main purpose is to provide real-time data on the posture of the plug-in material to support subsequent automated operations.
[0028] Furthermore, the gripping mechanism 150 can grip the insert material according to the information obtained by the identification mechanism 130 and rotate around an axis extending in the vertical direction. This rotation function can be achieved by a manual adjustment device, such as the operator rotating the gripping head angle to adapt to the direction of the insert material, or by a pneumatic motor driving the rotating platform to complete the attitude adjustment, thereby ensuring that the insert material maintains a stable attitude during the transfer process.
[0029] The correction mechanism 140 is used to adjust the insert material to the pin-down position. Specifically, the mechanism can be implemented using a gravity guide groove structure. For example, the insert material will automatically flip under the action of gravity when it slides on the inclined guide rail, or the insert material can be oriented in vibration by a vibration table and a limiting baffle. Its main purpose is to eliminate the directional deviation of the insert material to meet the requirements of the insertion process.
[0030] Therefore, this application integrates automatic identification and dynamic correction mechanisms to replace manual sorting operations, enabling the orientation correction of insert materials without human intervention, thereby achieving automated feeding of different types of insert materials. As a preferred implementation, when the above-mentioned mechanisms work together, the identification information directly guides the grasping and correction actions, avoiding the insertion failure problem caused by incorrect orientation in traditional methods.
[0031] The flexible vibrating feeder is compatible with two or more materials. Through the collaborative design of the identification mechanism and the correction mechanism, it completely solves the common problems in the plug-in field, such as the incompatibility of feeding devices, frequent material changes leading to low efficiency and high changeover costs. It can greatly expand the application scenarios of plug-in feeding, significantly improve the automation level of plug-in production lines, reduce manual intervention, greatly reduce enterprise manufacturing costs, and improve the automation level of production lines.
[0032] During the operation of the plug-in feeding device 100, the flexible vibrating tray 120 first vibrates and organizes the placed plug-in materials, automatically arranging them in an orderly manner and reducing stacking, thus providing a stable foundation for subsequent identification. The identification mechanism 130 uses image acquisition technology to obtain identification information of the plug-in materials to be fed into the flexible vibrating tray 120, including position and orientation data, providing real-time basis for automated processing.
[0033] Furthermore, the gripping mechanism 150 accurately grips the insert material based on the identification information and rotates along a vertically extending axis to adjust the orientation of the insert material, ensuring its stability during transfer. The insert material is then transferred to the correction mechanism 140. The correction mechanism 140 dynamically calculates the required correction angle based on the identification information and rotates the insert material so that the pins are facing downwards, preparing it for the insertion process.
[0034] In a preferred embodiment, the flexible vibrating tray 120 can specifically be a spiral flexible vibrating tray 120, the identification mechanism 130 can specifically be a high-resolution CCD camera, the gripping mechanism 150 can specifically be a vacuum suction gripping head, and the alignment mechanism 140 can specifically be a servo motor-driven rotary fixture. Therefore, this technical solution effectively avoids the inefficiency and orientation errors caused by manual handling of insert materials, achieves automated feeding of insert materials of different types or specifications, and ensures that the insert material pins face downwards, thus providing a reliable foundation for the insertion process.
[0035] An insertion machine is a mechanical device that inserts electronic components with leads into conductive vias on a printed circuit board. The insertion feeding device 100 is the core component of the insertion machine. Because circuit boards require the insertion of different types or specifications of components, in existing technology, manual sorting and placement of these components onto the insertion feeding device 100 is necessary to ensure accurate gripping by the machine's clamping head.
[0036] In the plug-in feeding device 100, the correction mechanism 140 is used to make the plug-in material pins face downward. However, in this process, due to the lack of a precise control mechanism for the rotation angle and a temporary fixing means for the plug-in material, the plug-in material is prone to displacement or angular deviation during correction, which affects the subsequent insertion accuracy.
[0037] For this, please refer to Figure 2 This application further proposes a correction mechanism 140 including a rotary drive 141, a rotary frame 142, and a fixing component. The rotary drive 141 is mounted on the mounting frame 110 and is connected to the rotary frame 142 in a transmission manner. The rotary drive 141 can drive the rotary frame 142 to rotate at a corresponding angle along the horizontally extending axis according to the identification information of the plug-in material obtained by the identification mechanism 130. The fixing component is mounted on the rotary frame 142 and is used to temporarily fix the plug-in material.
[0038] Among them, the rotary drive component 141 refers to the actuator that provides precise rotational power, which can be implemented by a servo motor, stepper motor or hydraulic rotary motor, with the purpose of dynamically calculating and executing a specific rotation angle based on the identification information; the rotary frame 142 refers to the support structure that carries the plug-in material and realizes the rotation function, which can be implemented by a metal frame or composite material platform, with the purpose of providing a stable rotation base and matching the vertical direction of the plug-in material pins; the fixing component refers to the device that temporarily constrains the plug-in material during rotation, which can be implemented by a mechanical clamping mechanism, electromagnetic chuck or elastic buckle structure, with the purpose of preventing the plug-in material from displacing due to inertia or vibration.
[0039] Specifically, the solution of this application establishes a reliable support foundation through the stable connection between the rotary drive component 141 and the mounting frame 110. After receiving the plug-in material identification information transmitted by the identification mechanism 130, the rotary drive component 141 analyzes the current position of the plug-in material in real time and calculates the required rotation angle, thereby driving the rotating frame 142 to rotate precisely to the target position along the horizontal axis. At the same time, the fixing component starts immediately after the plug-in material is transferred to the rotating frame 142, firmly fixing the plug-in material to the surface of the rotating frame 142, ensuring that the plug-in material and the rotating frame 142 maintain synchronous movement during the rotation. When the rotating frame 142 completes the specified angle rotation, the plug-in material pins naturally adjust to the downward state, forming a positioning posture that meets the requirements of the insertion process, thereby achieving precise correction of the plug-in material pin direction.
[0040] As a specific implementation method, the solution of this application is implemented as follows: the rotary drive component 141 can be a high-precision servo motor, the rotary frame 142 can be a lightweight aluminum alloy frame structure, and the fixing component can be a pneumatically driven clamping arm. The inner surface of the clamping arm is provided with an anti-slip rubber layer to enhance the fixing effect. The clamping arm is controlled to open and close by the action of the cylinder, and can quickly clamp the insert material body after the insert material is placed in place.
[0041] The above technical solution effectively solves the displacement problem caused by inaccurate angle control and lack of temporary fixation during the correction process of plug-in materials, ensuring that the pins of the plug-in materials can face down accurately, and improving the positioning accuracy and process stability of subsequent insertion.
[0042] Specifically, in some of the embodiments described above in this application, a fixing component is proposed to temporarily fix the plug-in material. However, in the implementation process, the fixing component may not be able to firmly fix the plug-in material, causing the plug-in material to shift or fall off when the rotating frame 142 rotates, affecting the correction accuracy and feeding reliability.
[0043] For this, please refer to Figure 2This application further proposes that the rotating frame 142 is provided with an adsorption hole 143, the fixing component is an adsorption component, and the adsorption component is connected to the adsorption hole 143. The adsorption component can adsorb and fix the plug-in material to the rotating frame 142 through the adsorption hole 143.
[0044] In practical applications, the adsorption hole 143 refers to the fluid channel opened on the rotating frame 142 for connecting the adsorption component. It can be implemented using a circular, rectangular, or polygonal hole structure. The purpose is to provide an adsorption path and ensure the precise positioning of the adsorption point, avoiding interference from external structures with the adsorption effect. The fixing component, also known as the adsorption component, is a device that uses the principle of negative pressure to fix the plug-in material. It can be implemented using a vacuum suction cup, an electromagnetic adsorption unit, or a pneumatic adsorption head. The purpose is to reduce physical contact with the plug-in material pins, avoid damage, and improve the adaptability and gentleness of the fixing process. Specifically, the connection between the adsorption component and the adsorption hole 143 means that the adsorption component establishes a fluid connection with the adsorption hole 143 through a pipe or direct integration. This can be achieved using a flexible hose connection, an internal channel, or an integrated design. The purpose is to efficiently transmit the adsorption force and prevent airflow disturbance during rotation from weakening the adsorption effect, thereby enhancing the reliability of the fixing.
[0045] Specifically, the solution of this application connects the adsorption hole 143 on the rotating frame 142 with the adsorption component, so that the negative pressure generated by the adsorption component acts on the surface of the insert material through the adsorption hole 143, thereby firmly adsorbing and fixing the insert material to the rotating frame 142; when the rotating drive 141 drives the rotating frame 142 to rotate around the horizontally extending axis, the adsorbed and fixed insert material rotates synchronously with the rotating frame 142, eliminating the relative displacement caused by rotational inertia, ensuring that the insert material pins are accurately adjusted to the downward position, and at the same time, the adsorption method replaces mechanical clamping, reducing the mechanical stress on the insert material, and ensuring the accuracy of the correction process and the stability of the feeding.
[0046] As a preferred embodiment, the solution of this application is specifically implemented as follows: The rotating frame 142 is made of aluminum alloy material, and multiple circular adsorption holes 143 are evenly distributed on it; the adsorption component is specifically a vacuum suction cup, which is connected to the adsorption holes 143 through a flexible hose. The vacuum suction cup is provided with a negative pressure source by the air extraction unit. When the insert material is placed on the rotating frame 142, the air extraction unit is activated, and the insert material is adsorbed and fixed through the adsorption holes 143, so that the insert material maintains a stable posture during the rotation.
[0047] The above solution effectively solves the problem of material displacement or detachment during rotation, improving the accuracy of correction and the reliability of feeding.
[0048] In some embodiments of this application, an identification mechanism 130 is proposed to identify the plug-in material to be loaded into the flexible vibrating tray 120. However, in this process, the vibration generated by the flexible vibrating tray 120 during operation and the change of ambient light can easily cause the plug-in material image to become blurred or have insufficient contrast, resulting in a decrease in identification accuracy and affecting the accuracy of subsequent gripping and correction operations.
[0049] For this, please refer to Figure 3 This application further proposes an identification mechanism 130 including a vision camera 131 and a supplementary lighting component 132. Both the vision camera 131 and the supplementary lighting component 132 are mounted on the mounting frame 110. The vision camera 131 is used to identify the plug-in materials to be loaded in the flexible vibrating tray 120, and the supplementary lighting component 132 is used to supplement the light on the plug-in materials in the flexible vibrating tray 120.
[0050] The vision camera 131 is an optical imaging device used to capture images of the insert material. It can be implemented using a CMOS image sensor or a CCD image sensor, with the aim of acquiring high-resolution images of the insert material to support accurate identification. The supplementary lighting component 132 is a light source device that provides stable illumination. It can be implemented using an LED array or a ring light source, with the aim of enhancing the uniformity of illumination on the surface of the insert material, reducing shadows and scattering, and improving image contrast. Mounting on the mounting frame 110 means fixing the vision camera 131 and the supplementary lighting component 132 to a rigid support structure. It can be implemented using a flange connection or bracket fixation, with the aim of utilizing the stability of the mounting frame 110 to prevent the vibration of the flexible vibrating tray 120 from being transmitted to the optical component.
[0051] Specifically, the supplementary lighting component 132 provides a directional and stable light source that directly illuminates the insert material in the flexible vibrating tray 120, effectively suppressing light fluctuations caused by vibration. With the assistance of the supplementary lighting component 132, the vision camera 131 can continuously capture clear, high-contrast images of the insert material. Since both the vision camera 131 and the supplementary lighting component 132 are mounted on the mounting frame 110, their rigid structure isolates the vibration interference of the flexible vibrating tray 120, ensuring the stability of the image acquisition process, thereby achieving reliable recognition in dynamic environments.
[0052] As a preferred embodiment, the solution of this application is implemented as follows: the vision camera 131 adopts an industrial-grade CMOS camera and is installed above the mounting frame 110, facing the working area of the flexible vibrating tray 120; the supplementary lighting component 132 adopts a high-brightness LED ring light, which is arranged around the vision camera 131 to provide uniform side lighting, so that the insert material can still maintain good image quality during vibration.
[0053] Through the above solution, this application can effectively solve the problem of recognition accuracy caused by vibration and changes in ambient light when the flexible vibrating material tray 120 is working, and ensure that the recognition mechanism 130 outputs accurate plug-in material information, providing a reliable basis for subsequent gripping and correction operations.
[0054] Specifically, in some embodiments of this application, a supplementary lighting component 132 is proposed to supplement the light on the plug-in material in the flexible vibrating tray 120. However, in its implementation, the installation position of the supplementary lighting component 132 may cause its physical structure to block the line of sight of the vision camera 131, making it impossible for the vision camera 131 to clearly capture the image of the plug-in material, thereby affecting the recognition accuracy and feeding reliability.
[0055] For this, please refer to Figure 3 This application further proposes that the supplementary lighting component 132 includes a supplementary lighting plate with a clearance hole 133, and the vision camera 131 can identify the plug-in material to be loaded in the flexible vibrating tray 120 through the clearance hole 133.
[0056] The supplementary lighting plate refers to the component used to provide illumination. It can be implemented using LED light panels, halogen light panels or fluorescent light panels. Its purpose is to provide a uniform and stable lighting environment for the plug-in materials in the flexible vibrating tray 120. The clearance hole 133 can be understood as a hole opened on the supplementary lighting plate. It can be implemented using circular, square or polygonal holes. Its purpose is to allow the line of sight of the vision camera 131 to pass through without physical obstruction.
[0057] Specifically, the solution of this application precisely matches the optical axis direction of the vision camera 131 with the opening position of the clearance hole 133, so that when the light-filling plate provides uniform illumination, its physical structure will not obstruct the line of sight of the vision camera 131. Thus, while the light-filling component 132 is working continuously, the vision camera 131 can directly obtain a clear image of the plug-in material through the clearance hole 133, ensuring that the dual functions of sufficient light and unobstructed line of sight are achieved simultaneously.
[0058] As a specific implementation, the fill light plate can be a rectangular LED light plate, and the clearance hole 133 can be a circular hole located in the central area of the fill light plate and aligned with the lens axis of the visual camera 131.
[0059] Through the above solution, this application avoids the physical obstruction of the line of sight of the visual camera 131 by the supplementary lighting component 132, ensuring the clarity and accuracy of the recognition process, thereby improving the reliability and efficiency of the plug-in feeding.
[0060] In some of the solutions described above in this application, a flexible vibrating tray 120 is proposed for placing and vibrating the insert material. However, in this process, the specific structure of the flexible vibrating tray 120 is not limited, which may lead to unstable vibration effect, insufficient sorting of insert material, and affect the accuracy of subsequent identification and grasping.
[0061] For this, please refer to Figure 5 This application further proposes a flexible vibrating tray 120 including a tray 121 and a vibration component 122. The vibration component 122 is mounted on the mounting frame 110, and the tray 121 is mounted on the vibration component 122. The vibration component 122 can drive the tray 121 to vibrate.
[0062] Specifically, the material tray 121 refers to the container structure used to hold the insert material, which can be a disc-shaped structure made of metal or plastic, with the purpose of providing a stable platform for placing the insert material; the vibration component 122 can be understood as a driving device that generates periodic vibration, which can be implemented by an electromagnetic vibrator or an eccentric wheel motor, with the purpose of providing a controllable vibration source for the material tray 121; in practical applications, the mounting frame 110 is specifically the frame structure that supports the entire device, such as a rigid metal frame, with the purpose of ensuring the stability of the device and the efficiency of vibration transmission.
[0063] Specifically, the vibration assembly 122 is mounted on the mounting frame 110 to obtain a stable support foundation and reduce energy loss; the material tray 121 is mounted on the vibration assembly 122 so that the vibration energy is efficiently transmitted to the surface of the material tray 121; the vibration assembly 122 drives the material tray 121 to vibrate, so that the insert material responds quickly in the material tray 121 and is placed at the bottom of the material tray 121 without interference, laying the foundation for the subsequent identification mechanism 130 to accurately capture the position of the insert material.
[0064] As a preferred embodiment, the solution of this application is specifically implemented as follows: the vibration component 122 is specifically an electromagnetic vibrator, the material tray 121 is a circular tray made of stainless steel, and the mounting frame 110 is made of aluminum alloy profile.
[0065] Through the above solution, the vibration effect of this application is more stable, the plug-in materials are more properly organized, and the accuracy of subsequent identification and grasping is improved.
[0066] Specifically, in some embodiments of this application, a gripping mechanism 150 is proposed for gripping and transferring plug-in materials. However, in its implementation, the gripping mechanism 150 can only rotate along the vertical axis and cannot dynamically adjust the pin orientation according to the actual direction of the plug-in materials. This results in the plug-in materials' orientation not matching the rotation axis of the correction mechanism 140 when they are transferred to the correction mechanism 140, which increases the adjustment burden and time of the correction mechanism 140 and reduces the feeding efficiency and accuracy.
[0067] For this, please refer to Figure 1 and Figure 4 This application further proposes a gripping mechanism 150 including a position adjustment component, a rotation component 154, and a gripping component 155. The rotation component 154 is mounted on the position adjustment component, and the gripping component 155 is mounted on the rotation component 154. The gripping component 155 is used to grip the plug-in material in cooperation with the position adjustment component. The rotation component 154 can rotate the plug-in material according to the identification information of the plug-in material obtained by the identification mechanism 130 so that the extension direction of the pin of the plug-in material is perpendicular to the rotation axis of the correction mechanism 140.
[0068] In practical applications, the position adjustment component refers to the mechanism used to precisely position the gripping component 155 in three-dimensional space. It can be implemented using a multi-axis linkage platform or an articulated robotic arm structure. The purpose is to enable the gripping component 155 to flexibly move to the distribution position of the insert material in the flexible vibrating tray 120, ensuring the stability and accuracy of the gripping action. The rotation component 154 refers to the drive device capable of performing precise angular rotation. It can be implemented using a servo motor combined with a high-precision encoder or a stepper motor driven rotation mechanism. The purpose is to dynamically calculate and execute the rotation angle based on the recognition information, adjusting the insert material to the required direction. Specifically, the gripping component 155 refers to the execution unit used to reliably fix the insert material. It can be implemented using a mechanical gripper, an electromagnetic adsorption device, or a flexible vacuum adsorption unit. The purpose is to maintain the stability of the insert material's posture during position adjustment and rotation, preventing gripping failure.
[0069] Specifically, the position adjustment component first drives the gripping component 155 to move to a position above the insert material to be loaded within the flexible vibrating tray 120. With the cooperation of the position adjustment component, the gripping component 155 grips the insert material. Subsequently, the rotation component 154 calculates the angle required for the pin extension direction to be perpendicular to the rotation axis of the correction mechanism 140 based on the insert material identification information acquired in real time by the identification mechanism 130, and drives the gripping component 155 to rotate synchronously along with the insert material. Finally, the position adjustment component transfers the oriented insert material to the correction mechanism 140. Through this design, the insert material is already in an initial posture with the pin extension direction perpendicular to the rotation axis of the correction mechanism 140 before being transferred to it. This allows the correction mechanism 140 to complete the pin-down correction action with only a small rotation, thus forming a complete orientation adjustment chain.
[0070] As a preferred embodiment, the solution of this application is implemented as follows: The position adjustment component can be specifically implemented as a SCARA robot, whose base is fixed to the mounting frame 110, and the upper arm and lower arm constitute a rapid positioning mechanism in the XY plane; the rotation component 154 can be specifically implemented as a rotary table driven by a servo motor, which is installed on the end effector of the SCARA robot. The servo motor achieves ±0.1 degree rotational accuracy control through encoder feedback; the gripping component 155 can be specifically implemented as a three-finger adaptive mechanical gripper, whose gripper surface is covered with a flexible silicone layer, which can adapt to the shape contour of different specifications of plug-in materials. During operation, the SCARA robot moves above the plug-in material in the flexible vibrating tray 120, the mechanical gripper descends and grips the plug-in material, and the servo motor drives the rotary table to rotate the plug-in material so that the pin extension direction is perpendicular to the horizontal rotation axis of the correction mechanism 140 according to the orientation information of the plug-in material identified by the vision camera 131. Then the SCARA robot transfers the plug-in material to the correction mechanism 140.
[0071] Through the above solution, this application enables the plug-in material to be precisely adjusted so that the pin extension direction is perpendicular to the rotation axis of the correction mechanism 140 before it is transferred to the correction mechanism 140, thereby significantly reducing the adjustment range and time consumption of the correction mechanism 140 and improving the efficiency and positioning accuracy of plug-in feeding.
[0072] In some embodiments described above in this application, a position adjustment component is proposed to adjust the position of the gripping component 155. However, in this process, since the structure of the position adjustment component is not specifically defined, the position adjustment in three-dimensional space lacks precision and coordination, which easily leads to cumulative errors, affecting the accuracy of gripping the plug-in material, and thus interfering with the reliability of subsequent rotation and correction operations.
[0073] For this, please refer to Figure 1 This application further proposes a position adjustment assembly including an X-axis drive unit 151, a Y-axis drive unit 152, and a Z-axis drive unit 153. The X-axis drive unit 151 is mounted on the mounting frame 110, the Y-axis drive unit 152 is mounted on the X-axis drive unit 151, the Z-axis drive unit 153 is mounted on the Y-axis drive unit 152, and the rotation assembly 154 is mounted on the Z-axis drive unit 153.
[0074] In practical applications, the X-axis drive unit 151 refers to a drive unit that provides precise linear motion in the X direction. It can be implemented using a servo motor in conjunction with a ball screw structure or a linear motor. Its purpose is to ensure the reference stability of movement in the X direction, avoid overall structural swaying, and provide a reliable starting point for subsequent adjustments. The Y-axis drive unit 152 refers to a unit that provides drive in the Y direction. It can be implemented using a stepper motor in conjunction with a guide rail system or a hydraulic cylinder structure. Its purpose is to make the adjustment in the Y direction strictly dependent on the calibrated position in the X direction, thereby eliminating mutual interference between the X and Y axes and ensuring the accuracy of movement in the plane. Specifically, the Z-axis drive unit 153 refers to a drive unit that provides vertical movement in the Z direction. It can be implemented using a pneumatic lifting mechanism or an electric push rod. Its purpose is to make the adjustment in the height direction based on the precise positioning in the X and Y plane, avoid the superposition of vertical errors, and achieve independence and precision in height control.
[0075] Specifically, the solution of this application establishes a stable reference for X-direction movement by directly mounting the X-axis drive unit 151 to the mounting frame 110, thus preventing overall structural swaying. The Y-axis drive unit 152 is mounted on the X-axis drive unit 151, ensuring that the Y-direction displacement is strictly based on the calibrated position in the X-direction, eliminating mutual interference between the X and Y axes. The Z-axis drive unit 153 is mounted on the Y-axis drive unit 152, making the height adjustment entirely dependent on the precise positioning results in the X and Y planes, avoiding the accumulation of vertical errors. The rotating component 154 is mounted on the Z-axis drive unit 153, ensuring that the position of the rotation operation is precisely locked by the Z-axis drive unit 153. When the rotating component 154 adjusts the posture of the insert material according to the identification information, the position reference of the insert material remains stable. This hierarchical installation structure, by gradually relying on the positioning results of the previous level, forms a step-by-step calibration mechanism, significantly reducing the cumulative error in multi-axis adjustment and improving the overall gripping accuracy.
[0076] As a preferred embodiment, the solution of this application is implemented as follows: The X-axis drive unit 151 can be specifically a linear guide rail system driven by a servo motor, and its guide rail is fixed to the mounting frame 110; the Y-axis drive unit 152 can be specifically another servo motor mounted on the slider of the X-axis guide rail, driving the Y-axis moving platform; the Z-axis drive unit 153 can be specifically a pneumatic lifting mechanism mounted on the Y-axis moving platform, and its output end is connected to the rotating component 154; the rotating component 154 can be specifically a rotary cylinder, and its output shaft is fixedly connected to the suction head of the gripping component 155. During operation, the X-axis drive unit 151 first moves the gripping component 155 to a designated position above the flexible vibrating material tray 120, the Y-axis drive unit 152 then fine-tunes the Y-axis coordinate, the Z-axis drive unit 153 descends to grip the insert material and then rises, and finally the rotating component 154 adjusts the posture of the insert material according to the recognition information.
[0077] Through the above scheme, this application achieves high-precision position control of the gripping mechanism 150 in three-dimensional space, effectively reduces the cumulative error in the multi-axis adjustment process, improves the accuracy and stability of the gripping of plug-in materials, ensures the reliability of subsequent rotation and correction operations, and thus guarantees the continuity and consistency of the plug-in feeding process.
[0078] In some of the embodiments described above in this application, a gripping component 155 is proposed for gripping plug-in materials. However, in its implementation, the gripping method lacks a reliable fixing mechanism, which makes the plug-in materials easy to fall off or the pins damaged. In particular, during the position adjustment and rotation process, the rigid contact of the mechanical clamping causes the pins of the plug-in materials to bend or the position to shift, affecting the subsequent correction accuracy and feeding efficiency.
[0079] For this, please refer to Figure 4 This application further proposes that the gripping component 155 includes an adsorption head and an air extraction unit (not shown), the adsorption head is mounted on the rotating component 154, and the air extraction unit is connected to the adsorption head.
[0080] Specifically, the adsorption head refers to the component used to fix the plug-in material by adsorbing it with negative pressure. It can be implemented by a vacuum nozzle or a flexible silicone suction cup. Its purpose is to avoid direct compression of the plug-in material pins by mechanical clamping, thereby preventing the pins from bending or breaking. The air extraction unit refers to the device that provides a negative pressure source. It can be implemented by a miniature vacuum pump or a negative pressure generator. Its purpose is to generate and adjust the adsorption force so that the adsorption force can adapt to the material and weight of the plug-in material, ensuring that the plug-in material is firmly attached during dynamic operation.
[0081] Specifically, the solution of this application, through the coordinated operation of the adsorption head and the vacuum unit, forms a stable negative pressure when gripping the insert material, so that the surface of the insert material is in close contact with the adsorption head; during the movement of the position adjustment component in the X, Y or Z direction and the rotation of the rotating component 154, the vacuum unit continuously provides an adjustable negative pressure, effectively offsetting the risk of falling off caused by vibration or inertia; at the same time, the insert material in the adsorption state can rotate synchronously with the rotating component 154, and the pin direction can be adjusted to a state perpendicular to the rotation axis of the correction mechanism 140 without interrupting the adsorption, providing a continuous and smooth transition for the subsequent correction operation of the insert material with the pin facing down.
[0082] As a specific implementation method, the adsorption head can be a silicone nozzle to adapt to the slight deformation of the surface of different plug-in materials; the air extraction unit can be a miniature vacuum pump, which is connected to the adsorption head through a hose to realize real-time dynamic adjustment of negative pressure.
[0083] By employing the above-mentioned solution, this application avoids the physical damage to the pins of the plug-in material caused by traditional mechanical clamping, improves the stability and reliability of the gripping process, thereby ensuring the precise positioning of the plug-in material during transfer and rotation, and effectively guaranteeing the subsequent correction accuracy and feeding efficiency.
[0084] In another embodiment, this application also discloses a plug-in machine, including a plug-in material device and the aforementioned plug-in feeding device 100, wherein the plug-in material device is used to insert the plug-in material fed by the plug-in feeding device 100 onto the circuit board.
[0085] The core innovation of this embodiment lies in the fact that by integrating the automated plug-in feeding device 100 with the plug-in material device, the manual handling of plug-in materials is eliminated, realizing full automation from plug-in material preparation to circuit board insertion. This achieves the effects of improving insertion accuracy and production efficiency, and reducing the risk of human error.
[0086] Specifically, the insertion feeding device 100 automatically adjusts the orientation of the insertion material based on the image information of the insertion material acquired by the recognition mechanism 130. For example, the recognition mechanism 130 generates a correction command based on the position and orientation data of the insertion material captured by the vision camera 131. The correction mechanism 140 then rotates the insertion material to a pin-down position, enabling the system to adapt to insertion materials of different specifications without manual preset or intervention. The insertion material device directly uses the standardized insertion materials output by the feeding device for insertion. Since the orientation of the insertion material has been accurately corrected by the automatic correction of the feeding device, the insertion material device can efficiently and stably insert the insertion material into the conductive vias of the circuit board, ensuring the continuity and reliability of the insertion process.
[0087] The flexible vibrating feeder is compatible with two or more materials. Through the collaborative design of the identification mechanism and the correction mechanism, it completely solves the common problems in the plug-in field, such as the incompatibility of feeding devices, frequent material changes leading to low efficiency and high changeover costs. It can greatly expand the application scenarios of plug-in feeding, significantly improve the automation level of plug-in production lines, reduce manual intervention, greatly reduce enterprise manufacturing costs, and improve the automation level of production lines.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
