Description

Technical Field

[0001] This utility model relates to the field of chip inspection technology, and in particular to a chip appearance inspection component and visual recognition device with multi-angle illumination. Background Technology

[0002] In today's era of rapid technological advancement, chips, as core components of electronic devices, are of paramount importance in terms of quality and performance stability. The integrity of a chip's appearance directly impacts its functionality and reliability. Therefore, comprehensive and accurate inspection of the chip's appearance is an essential and crucial step in the chip manufacturing process.

[0003] Currently, common chip appearance inspection methods mainly rely on manual visual inspection or traditional single-angle imaging equipment. Manual visual inspection has many limitations. On the one hand, due to human visual fatigue and subjective judgment differences, the inspection results are prone to inaccuracy and inconsistency, making it difficult to guarantee inspection quality. On the other hand, manual inspection is inefficient and cannot meet the high-speed inspection requirements of large-scale chip production, increasing production costs and production cycles.

[0004] While traditional single-angle imaging inspection equipment improves inspection efficiency to some extent, it still has significant shortcomings. Due to the complex structure of chips, which have multiple different surfaces and features, single-angle imaging cannot obtain complete information about the chip's appearance, easily missing some minor defects such as scratches, cracks, and stains. This leads to incomplete inspection and cannot effectively guarantee the quality of the chips. To address the aforementioned issues, this technical solution proposes a chip appearance inspection component and visual recognition device with multi-angle illumination. Utility Model Content

[0005] The purpose of this invention is to solve the problems of fatigue, low efficiency, and incomplete coverage of manual inspection by shooting from a single angle, and to propose a chip appearance inspection component and visual recognition device with multi-angle illumination.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A chip appearance inspection component with multi-angle illumination, comprising: Base; Mounting plate I and mounting plate II are fixedly installed on the top of the base; A support plate is fixedly installed on one side of the mounting plate I; A rotating disk is rotatably connected to one side of the mounting plate II; A drive motor is fixedly installed on one side of the support plate, and its output shaft is connected to the rotating plate through a connecting shaft to drive the rotating plate to rotate. Multiple clamping mechanisms are equally spaced between the support disk and the rotating disk for clamping the chip module; The clamping mechanism includes a support shaft, a support plate, a limiting rod, a support plate, a rotating shaft, a transmission gear, an electric push rod, and a clamping plate; The support shaft passes through the rotating disk and is rotatably connected to it. The tray is fixed to one end of the support shaft. The limiting rod is symmetrically fixed to one side of the tray. The support plate is fixed to the end of the limiting rod. The rotating shaft is fixed to one side of the support plate and passes through the support ring and is rotatably connected to it. The transmission gear is fixed to one end of the rotating shaft. The electric push rod is fixed to one side of the tray. The clamping plate is slidably sleeved on the limiting rod and connected to the output shaft of the electric push rod. An arc-shaped rack is fixed to one side of the support disk and engages movably with the transmission gear, used to drive the chip module to rotate when the rotating disk rotates.

[0007] In one possible design, an annular protective housing is fixedly installed on one side of the support plate to protect the transmission gear and the arc-shaped rack.

[0008] In one possible design, the output shaft of the drive motor is fixedly connected to one end of the connecting shaft via a coupling.

[0009] In one possible design, the clamping plate is disposed opposite to the support plate for clamping the chip module.

[0010] A visual recognition device, applied to a chip appearance inspection component with multi-angle illumination as described above, includes: The detection cover is fixedly installed on the top side of the support plate, and its top extends above the support plate; Multiple cameras are fixedly installed at equal intervals on the top inner wall of the detection cover for multi-angle imaging of the rotating chip module; Lighting tubes are symmetrically and fixedly installed inside the detection cover to provide stable illumination; A handheld display, wirelessly connected to multiple cameras, is used to receive and display captured images.

[0011] In one possible design, multiple cameras are arranged around the detection area of ​​the chip module.

[0012] In one possible design, the lighting tube is an LED tube.

[0013] In one possible design, the inner wall of the detection cover is provided with a reflective coating to enhance the uniformity of illumination.

[0014] In this application, during use, multiple chip modules are first placed sequentially within the limiting components of the corresponding clamping mechanisms, specifically between the clamping plate and the support plate. Then, the electric push rod is activated, its output shaft driving the clamping plate along the two limiting rods towards the support plate. With the support of the support plate, the chip modules are positioned and clamped. Next, the drive motor located inside the mounting box on one side of the fixing ring is activated, its output shaft driving the connecting shaft to rotate. Since the connecting shaft is connected to the rotating disk, it in turn drives the rotating disk to rotate. When the rotating disk rotates, it causes the multiple clamping mechanisms connected to it to perform a circular motion, causing the clamped chip modules to move accordingly. This moves the chip modules to the area inside the detection cover where they are photographed and detected. During the movement of the module to the testing area, the transmission gear at one end of the rotating shaft meshes with the arc-shaped rack on the top side of the support plate. The transmission gear rotates during its arc-shaped movement, driving the chip module to rotate via the rotating shaft. Simultaneously, two symmetrically fixed lighting tubes inside the testing cover provide stable illumination. Multiple cameras, evenly spaced and fixed on the inner wall of the top of the testing cover, capture images of the rotating chip module from multiple angles. The images captured by the multiple cameras are transmitted wirelessly to the same handheld display. The operator views the images on the handheld display, thus conducting a comprehensive inspection of the chip module's appearance. A ring-shaped protective shell fixed on one side of the support plate protects the transmission gear and the arc-shaped rack.

[0015] Beneficial effects: In this utility model, the multi-angle illumination chip appearance inspection component, through the clamping mechanism, can drive the connecting shaft to rotate by starting the drive motor, which in turn drives the rotating disk to rotate. When the rotating disk rotates, it can drive multiple clamping mechanisms to perform circular motion, thereby driving the clamped chip module to move and move the chip module to the area for chip module imaging and inspection. This invention overcomes the problems of fatigue, low efficiency, and incomplete coverage caused by manual inspection and single-angle shooting. By driving a motor to make the chip move in a ring, and the transmission gear and arc rack working together to make the chip rotate, combined with multi-camera multi-angle shooting and stable lighting, it can comprehensively and accurately inspect the chip appearance, ensure chip quality, and meet the needs of large-scale production.

A rotating disk 8 is rotatably connected to the top of one side of mounting plate II3 via a bearing.

[0020] Multiple clamping mechanisms are equally spaced between the support plate 6 and the rotating plate 8. The drive motor 7 located in the mounting box 4 is fixedly installed on one side of the fixing ring 5 by bolts. A connecting shaft 23 is welded to the center of the rotating plate 8 near the support plate 6. The connecting shaft 23 passes through the support plate 6 and is rotatably connected to the support plate 6 through a bearing. The output shaft of the drive motor 7 is fixedly connected to one end of the connecting shaft 23 by a coupling.

[0021] like Figure 6 As shown, a multi-angle illumination chip appearance inspection component includes a clamping mechanism in which a support shaft 10 passes through a rotating disk 8 and is rotatably connected to the rotating disk 8 via a bearing. A limit assembly support plate 11 is welded to one end of the support shaft 10. Two limit rods 111 are symmetrically welded to one side of the support plate 11. A common support plate 13 is welded to one end of each limit rod 111. A rotating shaft 15 is welded to one side of the support plate 13, passing through a support ring 9 and rotatably connected to the support ring 9 via a bearing. An electric push rod 17 is bolted to one side of the support plate 11. A clamping plate 12 is slidably fitted onto the two limit rods 111. The output shaft of the electric push rod 17 is bolted to one side of the clamping plate 12. When a chip module 14 is placed between the clamping plate 12 and the support plate 13, the electric push rod 17 is activated.

[0023] The drive motor 7 is started, and its output shaft drives the connecting shaft 23 to rotate, which in turn drives the rotating disk 8 to rotate. The rotating disk 8 drives multiple clamping mechanisms to perform a circular motion, moving the clamped chip module 14 to the detection area. During the movement of the chip module 14 to the detection area, the transmission gear 16 and the arc-shaped rack 18 maintain meshing transmission. The transmission gear 16 rotates during the arc-shaped motion, driving the chip module 14 to rotate through the rotating shaft 15.
