Description

Technical Field

[0001] This utility model relates to the field of surface inspection technology for parts, and in particular discloses a planar inspection platform structure. Background Technology

[0002] Planar inspection platforms play a crucial role in modern manufacturing and automated industries, widely used in areas such as workpiece surface quality inspection and post-processing of precision machining. With increasing demands for high-precision machining, traditional inspection platforms often employ fixed robotic arms or relatively simple moving mechanisms for surface inspection. However, these existing technologies have several shortcomings: Firstly, due to the limitations of a single drive system, existing platforms often cannot achieve comprehensive and accurate inspection of the workpiece surface, especially when inspecting large or complex-shaped workpieces, frequently resulting in blind spots or uncovered areas. Secondly, the control systems of existing platforms are generally rudimentary, unable to provide real-time and accurate feedback and position control, leading to unstable inspection accuracy. Furthermore, the poor operational flexibility and low degree of automation of traditional equipment also limit their application in modern, efficient production.

[0003] Therefore, how to improve detection accuracy and efficiency through precise mechanical design and intelligent control system without increasing equipment complexity has become an urgent problem to be solved in the field of planar inspection platforms. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a planar detection platform structure to solve the technical problems of poor operational flexibility and low detection accuracy in the existing technology.

[0005] To achieve the above objectives, the present invention provides a planar inspection platform structure, comprising a mounting frame for limiting an external workpiece to be inspected, a first robotic arm assembly configured in conjunction with the mounting frame, and a support platform. The first robotic arm assembly is reciprocally mounted on the support platform, and its end is used to mount an external inspection device. The invention also includes an electrical control component electrically connected to the first robotic arm assembly, which controls the first robotic arm assembly to drive the inspection device to perform surface inspection on the workpiece limited by the mounting frame.

[0006] Furthermore, the first robotic arm assembly includes a first drive unit that reciprocates along the X-axis, a second drive unit that reciprocates along the Y-axis, and a third drive unit that reciprocates along the Z-axis. The first and second robotic arm assemblies are used to drive an external detection device to perform surface detection on the workpiece to be tested, which is limited by the mounting frame.

[0007] Furthermore, the first drive unit includes a first slide rail disposed on the support platform, a first slider slidably disposed on the first slide rail, a first mover disposed on the first slider, and a first stator disposed on the support platform; the first stator includes a stator mounting frame disposed on the support platform and two sets of magnet groups disposed on the inner wall of the stator mounting frame, the first mover being located between the two sets of magnet groups, and the magnet groups including a plurality of permanent magnets with alternating polarities.

[0008] Furthermore, the number of the first drive units is at least two sets, with the two sets of first drive units respectively set on the top two sides of the support platform. The structure of the second drive unit is the same as that of the first drive unit. The second drive unit is connected to the power output end of the two sets of first drive units, and the third drive unit is connected to the power output end of the second drive unit.

[0010] Furthermore, the support platform includes a base, a first bracket and a second bracket disposed on both sides of the base, and a third bracket connected between the first bracket and the second bracket. The extension direction of the first bracket is perpendicular to the extension direction of the base, and the third bracket is mounted on top of the first bracket and the second bracket.

[0011] Furthermore, the first bracket, the second bracket, and the third bracket form a gantry structure above the base.

[0012] Furthermore, the first drive unit is provided in two sets, with the two sets of first drive units respectively disposed above the first bracket and the second bracket, and the second drive unit disposed on the third bracket. The first slide rail of the first drive unit is arranged along the X-axis, the first slide rail of the second drive unit is arranged along the Y-axis, and the second slide rail of the third drive unit is arranged along the Z-axis.

[0013] Furthermore, the base is provided with a first through hole, and the mounting bracket is provided with a second through hole. The first through hole of the base is connected to the second through hole of the mounting bracket, and the part of the workpiece to be tested is exposed through the first through hole and the second through hole.

[0014] Furthermore, the planar detection platform structure also includes a position feedback component, which includes a grating detection unit. The grating detection unit includes a grating ruler disposed on the support platform and a sensor disposed on the power output end of the first robotic arm assembly. The first robotic arm assembly is electrically coupled to the electronic control component via the sensor. The sensor is used to sense the light signal generated by the grating ruler, thereby detecting the movement position of the detection device driven by the first robotic arm assembly, and feeding back the movement position information to the electronic control component. The electronic control component adjusts the movement stroke and movement speed of the first robotic arm assembly in real time according to the movement position information.

[0015] Furthermore, the sensing element includes a zero-position exciter, a reading head disposed on the zero-position exciter, and a signal processor.

[0017] Furthermore, the position feedback component also includes multiple sets of photoelectric sensors electrically connected to the electronic control component. These photoelectric sensors are installed on the opposite side of the output ends of the first and second robotic arm components (e.g., if the grating ruler is installed on the left side of the first support, then the photoelectric sensors are installed on the right side of the first support). The core advantage of this design is that it combines the target detection capability of the photoelectric sensor with the high-precision displacement measurement capability of the grating, achieving more stable, high-precision, and high-reliability control of the slide system. This makes it suitable for demanding applications such as precision manufacturing, semiconductor equipment, and automated assembly.

[0020] Furthermore, the planar inspection platform structure also includes a second robotic arm assembly. The second robotic arm assembly has the same structure as the first robotic arm assembly.

The third drive unit (Z-axis drive unit) of the second robotic arm assembly is used to drive the inspection device to reciprocate within the first through hole of the base, so that the front and back sides of the workpiece to be inspected are inspected simultaneously.

[0021] This utility model's planar inspection platform integrates multiple drive units and robotic arm components, enabling precise movement of both the workpiece and the inspection device in the X, Y, and Z directions, ensuring the inspection device covers all surfaces of the workpiece.

Furthermore, the position feedback component, through the collaboration of a grating ruler and a photoelectric photoelectric sensor, further improves the platform's positioning accuracy, achieving real-time tracking and adjustment during movement. This multi-layered and diversified control mechanism provides the planar inspection platform with efficient and precise performance.

[0033] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0034] Please see Figures 1 to 8As shown, the planar inspection platform structure of this utility model includes several core components, such as a mounting frame, a first robotic arm assembly, a support platform, and an electrical control assembly. It aims to provide a high-precision, high-efficiency inspection platform, addressing the shortcomings of existing technologies in workpiece surface inspection. First, the core component of the platform is the mounting frame, which is used to limit the workpiece to be inspected and ensure its stability and positional accuracy throughout the inspection process. The first robotic arm assembly, which works in conjunction with the mounting frame, supports external inspection devices and can precisely drive these devices to inspect the workpiece surface. The first robotic arm assembly reciprocates along the X, Y, and Z axes on the support platform, with each movement along the X, Y, and Z axes controlled by a corresponding drive unit. The electrical control assembly, through electrical cooperation with the first robotic arm assembly, can precisely regulate the movement of the robotic arm, ensuring that the inspection device accurately covers the workpiece surface for inspection.

[0035] In the specific design of the first robotic arm assembly, the first drive unit includes a first slide rail mounted on a support platform, a first slider slidably mounted on the slide rail, a first mover mounted on the slider, and a first stator mounted on the support platform. The stator includes a stator mounting frame on the support platform and two sets of permanent magnets on the inner wall of the stator. This design allows the first mover to slide precisely between the two sets of magnets, achieving high-precision movement control. Compared to existing technologies, using a permanent magnet drive method can significantly improve the stability and reliability of the drive unit, while reducing mechanical friction and energy loss in traditional electric drive systems, thus improving system efficiency and lifespan. To further enhance system precision, the first drive unit is equipped with at least two sets of drive units, respectively located on both sides of the top of the support platform. Through the coordinated action of these drive units, precise control of the platform along the X, Y, and Z axes is ensured.

[0036] Specifically, the third drive unit is designed with multiple components, including a connecting block located at the power output end of the second drive unit, a second slide rail, a first lead screw, and a second slider screwed to it. This design enables the third drive unit to move precisely back and forth in the Z-axis direction, driving the detection device to complete the workpiece detection task. Compared with existing technologies, the three-axis linkage drive design provides higher flexibility and accuracy, and is particularly suitable for the detection of large-sized or complex-shaped workpieces, ensuring comprehensive coverage and precise positioning of the workpiece surface by the detection device.

[0037] The support platform employs a gantry structure, with a first through-hole in the base and a second through-hole in the mounting bracket. These two sections are connected via the through-hole, ensuring that the portion of the workpiece to be inspected is exposed. This structural design not only guarantees that the inspection device can perform surface inspection from all angles without blind spots but also flexibly handles workpieces of different shapes and sizes, improving the platform's applicability and flexibility. The overall structure of the support platform is robust and reliable, capable of withstanding high loads and providing precise motion control.

[0038] To further improve the accuracy and stability of the detection process, this invention also includes a position feedback component, which comprises a grating detection unit and a photoelectric sensor. The grating detection unit works electrically with the electronic control unit to accurately sense the light signal generated by the grating ruler, detecting and feeding back the movement position of the first robotic arm assembly. Based on the feedback information, the electronic control unit adjusts the travel and speed of the first robotic arm assembly in real time, ensuring precise positioning of the detection device on the workpiece surface. The photoelectric sensor is used for target detection, further improving the accuracy and stability of the platform system. Combined with the high-precision displacement measurement of the grating ruler, this forms a dual guarantee, improving the system's reliability and control accuracy. Through this feedback mechanism, the platform can achieve real-time self-adjustment during the detection process, ensuring high accuracy and stability even in complex operating environments.

[0039] Furthermore, this invention takes into account the system's safety and protection by specifically designing anti-collision components. These components are installed at both ends of the first slider in the direction of movement and are integrally molded from silicone material. They effectively prevent collisions during movement, protecting mechanical parts and detection devices from damage, thereby improving the equipment's durability and stability. The use of anti-collision components also reduces equipment maintenance costs and failure rates, extending the platform's service life.

[0040] In terms of overall design, this utility model also includes a second robotic arm assembly, which has the same structure as the first robotic arm assembly. The mounting bracket is located at the power output end of the second drive unit of the second robotic arm assembly. The first and second robotic arm assemblies are located on the upper and lower sides of the support platform, respectively, ensuring that both the front and back sides of the workpiece can be fully inspected. The Z-axis drive unit of the second robotic arm allows the inspection device to move up and down reciprocally within the second through hole of the base, effectively achieving simultaneous inspection of both the front and back sides of the workpiece and further improving inspection efficiency.

[0041] In summary, this invention provides a highly efficient and precise planar inspection platform through the combination of precise mechanical design and an intelligent control system. This platform, with its three-axis linkage drive system, high-precision feedback mechanism, and protective design, not only improves inspection accuracy and work efficiency but also provides higher reliability and stability in practical applications. Compared to existing technologies, this invention has significant advantages and can better meet the needs of modern precision manufacturing and automated inspection fields.

The content of this specification should not be construed as a limitation of this utility model.
