Description

Technical Field

[0001] This utility model belongs to the technical field of terminal testing equipment, and in particular relates to a six-sided terminal testing mechanism. Background Technology

[0002] Currently, the visual inspection of electronic components mainly relies on manual labor. This method is prone to high error rates and low reliability, easily leading to missed or false detections. Although there are methods that use cameras for inspection, these methods cannot simultaneously detect multiple defects, requiring shooting from multiple angles, resulting in low efficiency and high costs. Furthermore, the fixed position of the camera in inspection equipment limits its application range; each time a product model is changed, corresponding inspection equipment usually needs to be replaced, increasing production costs and equipment space requirements.

[0003] Existing test sorting machines are mostly used in the integrated circuit design and packaging testing stages, primarily for automatically transferring chips for testing and marking, classifying, and collecting the chips based on the test results. However, existing test sorting machines generally lack comprehensive visual inspection capabilities. Therefore, to perform omnidirectional visual inspection of photovoltaic power modules, additional equipment is required, which not only increases costs but also leads to a larger equipment layout space.

[0004] In summary, current appearance inspection methods and equipment have many shortcomings, and there is an urgent need for a new solution that can simultaneously detect multiple appearance defects, improve inspection efficiency, and reduce costs. Utility Model Content

[0005] The purpose of this utility model is to provide a six-sided terminal inspection mechanism, which aims to solve the technical problem that the existing inspection equipment does not have a comprehensive appearance inspection function, and new equipment needs to be added, which leads to increased costs and equipment space.

[0006] To achieve the above objectives, this utility model provides a terminal six-sided detection mechanism, comprising: frame; A feeding mechanism is located at one end of the frame and is used to transport terminals; A rotating mechanism, adjacent to the feeding mechanism, is used to drive the terminals to rotate; wherein, the rotating mechanism is equipped with multiple clamps for fixing the terminals. Multiple detection units are distributed around the rotating mechanism and detect six sides of the terminal. A feeding mechanism is located at the other end of the frame and is used to remove terminals; The control system is electrically connected to the feeding mechanism, rotating mechanism, clamp, detection unit, and unloading mechanism to coordinate the operation of each component.

[0007] Optionally, the feeding mechanism includes a linear module, a tray, and a negative pressure conveying assembly. The linear module is used to convey the tray containing the terminals to the detection position, and the negative pressure conveying assembly is used to grip the terminals into the fixture of the rotating mechanism.

[0008] Optionally, the rotating mechanism includes a direct drive motor, a turntable, and a magnetic encoder. The output shaft of the direct drive motor is connected to the turntable, and the magnetic encoder is used to provide real-time feedback on the rotation angle of the terminals.

[0009] Optionally, the detection unit includes a visual inspection module and a laser inspection module. The visual inspection module is used to detect appearance defects of the terminal, and the laser inspection module is used to detect the size and internal structure of the terminal.

[0010] Optionally, the visual inspection module includes a high-resolution camera and a ring light source, the ring light source being arranged around the high-resolution camera to provide uniform illumination.

[0011] Optionally, the laser detection module includes a laser emitter and a laser receiver, which are symmetrically arranged on both sides of the rotating mechanism for laser scanning of the terminals.

[0012] Optionally, the clamp includes an adjustable clamp for clamping the terminals, the adjustable clamp being detachably connected to the rotating mechanism by bolts.

[0013] Optionally, the six-sided terminal inspection mechanism further includes a screening component, which is disposed between the rotating mechanism and the feeding mechanism, and performs good product classification on the terminals.

[0014] Optionally, the frame is provided with a defective product discharge port, which is located between the rotating mechanism and the feeding mechanism and is used to receive defective products.

[0015] Optionally, a return conveyor belt is provided at the bottom of the defective product discharge port.

[0016] The terminal six-sided detection mechanism provided in this utility model embodiment has at least one of the following technical effects: The terminal six-sided inspection mechanism provided in this embodiment integrates a frame, a feeding mechanism, a rotating mechanism, multiple inspection units, an unloading mechanism, and a control system to form an integrated inspection system. Firstly, by using the rotating mechanism to drive the terminal to rotate in conjunction with the surrounding inspection units, a one-time all-around inspection of all six sides of the terminal can be completed without multiple shots or equipment changes. This effectively solves the problems of low efficiency and the need for multi-angle shooting in existing technologies with fixed-position camera inspection, significantly improving inspection efficiency. Secondly, the control system coordinates the feeding, rotating, inspection, and unloading components to achieve automated inspection processes, reducing manual intervention and avoiding the high error rate, low reliability, and missed or false detection problems that easily occur with manual inspection. Thirdly, the overall mechanism has a high degree of integration, eliminating the need for additional appearance inspection equipment. This solves the problem of increased costs and larger equipment footprint caused by the lack of comprehensive appearance inspection functions in existing testing and sorting machines, thus reducing production costs and space requirements. Fourthly, through a unified mechanism design and adaptable fixture structure, it can adapt to the inspection needs of different terminal models, reducing equipment replacement frequency and further improving the equipment's versatility and economy.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a terminal six-sided detection mechanism is provided, comprising: Rack 10; The feeding mechanism 20 is located at one end of the frame 10 and is used to transport terminals; A rotating mechanism 30, adjacent to the feeding mechanism 20, is used to drive the terminals to rotate; wherein, the rotating mechanism 30 is equipped with a plurality of clamps 40 for fixing the terminals. Multiple detection units 50 are distributed around the rotating mechanism 30 and detect the six sides of the terminal. A feeding mechanism 60 is disposed at the other end of the frame 10 and is used to remove terminals; The control system is electrically connected to the feeding mechanism 20, the rotating mechanism 30, the clamp 40, the detection unit 50, the clamp 40 and the unloading mechanism 60, respectively, and is used to coordinate the operation of each component.

[0027] Specifically, the terminal six-sided inspection mechanism provided in this embodiment integrates a frame 10, a feeding mechanism 20, a rotating mechanism 30, multiple inspection units 50, an unloading mechanism 60, and a control system to form an integrated inspection system. Firstly, by using the rotating mechanism 30 to drive the terminal to rotate in conjunction with the surrounding inspection units 50, a one-time all-around inspection of the terminal's six sides can be completed without multiple shots or replacement of inspection equipment. This effectively solves the problems of low efficiency and the need for multi-angle shooting in existing technologies with fixed-position camera inspections, significantly improving inspection efficiency. Secondly, the control system coordinates the feeding, rotating, inspection, and unloading processes. The components work together to achieve an automated testing process, reducing manual intervention and avoiding the high error rate, low reliability, and missed or false detection problems that are prone to occur in manual testing. Thirdly, the overall mechanism has a high degree of integration, eliminating the need for additional appearance inspection equipment. This solves the problem of increased costs and larger equipment footprint caused by the lack of comprehensive appearance inspection functions in existing testing and sorting machines, thus reducing production costs and space occupation. Fourthly, through a unified mechanism design and adaptable fixture structure, it can adapt to the testing needs of different types of terminals, reducing the frequency of equipment replacement and further improving the versatility and economy of the equipment.

[0028] In another embodiment of this utility model, such as Figures 1-3 As shown, the feeding mechanism 20 includes a linear module 21, a tray 22, and a negative pressure conveying component 23. The linear module 21 is used to convey the tray 22 containing terminals to the detection position, and the negative pressure conveying component 23 is used to grip the terminals into the clamp 40 of the rotating mechanism 30. Specifically, the linear module 21 achieves stable conveying of the tray 22, ensuring the accuracy of the terminal feeding position. Combined with the negative pressure conveying component 23, which uses the principle of negative pressure adsorption to grip the terminals, it enables non-destructive and precise gripping and transfer of the terminals, avoiding the deformation or damage that may occur with traditional mechanical gripping. This further improves the stability and reliability of the feeding process, providing a prerequisite guarantee for the accuracy of subsequent testing. At the same time, the automated feeding process reduces manual intervention and works in conjunction with the control system, further improving the overall testing efficiency.

[0029] In another embodiment of this utility model, such as Figures 1-3As shown, the rotating mechanism 30 includes a direct-drive motor, a turntable 31, and a magnetic encoder. The output shaft of the direct-drive motor is connected to the turntable 31, and the magnetic encoder is used to provide real-time feedback on the rotation angle of the terminal. Specifically, a direct-drive motor is used to drive the turntable 31, reducing transmission errors and energy loss. The feedback information from the magnetic encoder enables the control system to precisely control the rotation of the terminal, improving detection accuracy and consistency.

[0030] In another embodiment of this utility model, such as Figures 1-3 As shown, the detection unit 50 includes a vision inspection module 51 and a laser inspection module 52. The vision inspection module 51 is used to detect appearance defects of the terminals, and the laser inspection module 52 is used to detect the dimensions and internal structure of the terminals. Specifically, the vision inspection module 51 and the laser inspection module 52 are integrated into the detection unit 50. The vision inspection module 51 focuses on appearance defects on the terminal surface, such as scratches, dents, stains, burrs, etc., while the laser inspection module 52 utilizes the high precision characteristics of lasers to perform non-contact and precise measurements of key dimensions (such as length, width, height, and aperture) and internal structures (such as internal holes, cavities, and wall thickness) of the terminals. This achieves comprehensive and multi-dimensional detection of the terminal's appearance and internal quality. Compared with single vision inspection or dimension inspection, the detection range is wider and the information is more comprehensive, effectively making up for the limitations of traditional detection methods and further improving the accuracy and comprehensiveness of terminal quality judgment, ensuring that defective products do not flow into subsequent processes.

[0031] In another embodiment of this utility model, such as Figures 1-3 As shown, the visual inspection module 51 includes a high-resolution camera and a ring light source. The ring light source is arranged around the high-resolution camera to provide uniform illumination. Specifically, the high-resolution camera can capture subtle appearance features of the terminal surface, ensuring that even tiny defects can be clearly imaged, providing high-quality image data for subsequent image analysis and defect identification. The ring light source, arranged around the high-resolution camera, can provide uniform and soft illumination to the terminal surface from multiple angles, effectively eliminating shadows and reflections, and avoiding the problems of low image contrast and difficulty in defect identification caused by uneven illumination.

[0032] In another embodiment of this utility model, such as Figures 1-3As shown, the laser detection module 52 includes a laser emitter and a laser receiver, which are symmetrically arranged on both sides of the rotating mechanism 30 for laser scanning of the terminals. Specifically, the laser emitter and laser receiver are symmetrically arranged on both sides of the rotating mechanism 30. When the terminal rotates with the rotating mechanism 30 and passes through the laser scanning area, the laser beam can scan the terminal in all directions. By analyzing the changes in the laser signal (such as propagation time, phase change, light intensity change, etc.), the various dimensional parameters and internal structural information of the terminal can be accurately calculated.

[0033] In another embodiment of this utility model, such as Figures 1-3 As shown, the clamp 40 includes an adjustable clamping plate 41 for clamping terminals, which is detachably connected to the rotating mechanism 30 by bolts. Specifically, the adjustable clamping plate 41 adapts to different terminal fixing requirements, and the detachable connection facilitates replacement and maintenance of the clamping plate, enhancing the adaptability of the testing mechanism to different terminals.

[0034] In another embodiment of this utility model, such as Figures 1-3 As shown, the six-sided terminal inspection mechanism also includes a screening component 70, which is disposed between the rotating mechanism 30 and the feeding mechanism 60, and performs good product classification on the terminals. Specifically, the screening component 70 automatically classifies good products according to the inspection results, realizing refined management and improving production continuity and automation.

[0035] In another embodiment of this utility model, such as Figures 1-3 As shown, the frame 10 has a defective product discharge port 71, which is located between the rotating mechanism 30 and the feeding mechanism 60 and is used to receive defective products. Specifically, the defective product discharge port 71 enables immediate separation of defective and good products, facilitating centralized collection and processing of defective products, and improving the cleanliness and controllability of the inspection and production process.

[0036] In another embodiment of this utility model, such as Figures 1-3 As shown, a return conveyor belt 72 is provided at the bottom of the defective product discharge port 71. Specifically, the return conveyor belt 72 at the bottom of the defective product discharge port 71 transports defective products to the recycling area or rework station, realizing automated transfer, reducing manual labor intensity, and improving the efficiency of defective product processing.

[0037] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
