Description

Technical Field

[0001] This invention relates to the field of surface defect detection technology, specifically to an intelligent inspection device for the production of smartwatch casings. Background Technology

[0002] A smartwatch is a wearable device that combines the functions of a smartphone and a wristwatch. It has core functions such as location tracking and anti-loss, audio and video calls, as well as multiple functions such as electronic payment, health monitoring, social chat, photography, and intelligent object recognition, and has a large market potential.

[0003] Optical inspection of smartwatch casings is a crucial step in modern precision manufacturing, primarily due to its stringent requirements for high precision, non-contact operation, and high efficiency. Traditional contact-based measurement methods are insufficient to meet the inspection needs of smartwatches and high-end mechanical watch casings, which feature complex curved surfaces, minute dimensions, and fragile materials. Therefore, optical inspection techniques are generally employed for intelligent inspection of smartwatch casings (addressing their complex geometry and minute dimensions).

[0004] An existing defect detection device, with application publication number CN116609336B, includes a sample stage; a first motion platform on which the sample stage is mounted, the first motion platform comprising a Y-axis motion unit, a Z-axis motion unit, and a T-axis motion unit: the Y-axis motion unit is used for moving the sample stage up and down and for stepping the sample stage; the Z-axis motion unit is used to adjust the vertical height of the sample stage; and the T-axis motion unit is used to adjust the angle between the sample stage and the horizontal plane to accommodate sample image recognition; a dual optical system, including a first optical module and a second optical module, for image recognition of the sample on the sample stage; and a second motion platform on which the dual optical system is mounted. This invention, through an automated detection unit, achieves automated surface defect detection operations for equipment and instruments, improving the efficiency of equipment and instrument detection.

[0005] However, this detection device (equipment) has the following defects in practical use:

[0006] Existing testing devices (equipment) typically employ optical inspection to improve the accuracy of optical inspection of equipment and instrument casings (including but not limited to smartwatches) when detecting surface defects. This method adapts to the complex dimensions and casings of the equipment and instruments, and enhances the effectiveness of optical inspection. Furthermore, to improve the efficiency of surface defect detection, automated equipment and devices are generally used to complete the optical inspection. However, in actual operation, these solutions require considerable time for disassembling, replacing, and installing the equipment (casing) to ensure its stability during inspection. Moreover, after each installation, the equipment (casing) must be moved back to the bottom of the inspection structure, further increasing the time required and resulting in low overall efficiency (optical) efficiency for surface defect detection of equipment (casings).

[0007] When performing surface defect (optical) inspection on the casing of instruments and equipment, highly reflective components (such as metal rings) on the surface of the casing will concentrate the projected light through specular reflection. The optical detection module on the detection structure may struggle to receive sufficient effective scattered light, easily leading to measurement blind spots, missing data, or sparse point clouds, thus affecting the completeness and accuracy of the inspection. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent inspection device for the production of smartwatch casings, in order to solve the problems mentioned in the background art.

[0036] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0037] 1. In the intelligent inspection device used in the production of smartwatch casings, when inspecting the surface defects of smartwatch casings (through optical inspection), a vertical drive source is activated to continuously rotate a rotating disk. This rotation changes the position of multiple smartwatch casings clamped and fixed at the eccentric top of the disk, moving each casing to be inspected to the bottom of the optical inspection module for surface defect detection. Furthermore, the concave design on one side of the guide disk automatically releases the smartwatch casings that have rotated to the concave side, facilitating the disassembly and replacement of the casings by workers or mechanical grippers. This improves the efficiency of optical inspection of smartwatch casings while enabling rapid disassembly, replacement, and re-inspection of the casings.

[0038] 2. In the intelligent inspection device for smart watch casing production, when the rotating disk is used to inspect the surface defects of smart watch casings at different locations, the force that drives the rotating disk to rotate can be transmitted via belt to drive the pusher piston to reciprocate inside the sealed tank. This automatically pushes the powder material into the sealed tank and automatically transfers it to the powder spraying nozzle for automated powder spraying (through atomized powder spraying). This automated powder spraying process is applied to the surface of each smart watch casing to be optically inspected, converting the strong specular reflection transmitted to the smart watch casing into diffuse reflection. This allows the camera unit of the optical inspection module to capture the reflected light more stably, avoiding the loss or distortion of data in the optical inspection of the smart watch casing.

[0039] 3. In the intelligent inspection device used in the production of smart watch casings, when performing surface defect inspection on the smart watch casing (using optical inspection), the device can automatically achieve high-precision surface defect inspection by moving the smart watch casing to be inspected longitudinally, moving the optical inspection module (the instrument performing optical inspection) horizontally, and moving it vertically.

[0065] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0066] Please see Figures 1-15 The intelligent inspection device for smartwatch casing production includes an inspection housing 10; a control terminal 20 installed on the side of the inspection housing 10; an optical inspection structure 30 electrically connected to the control terminal 20 and installed inside the inspection housing 10; and a rotary clamping pretreatment structure 40 electrically connected to the control terminal 20 and installed inside the inspection housing 10. The rotary clamping pretreatment structure 40 clamps and fixes the smartwatch casing to its inner side and performs powder coating pretreatment on the smartwatch casing. The rotary clamping pretreatment structure 40 is located on the side of the optical inspection structure 30 and includes: a longitudinal... The system includes: a positioning component 401; a vertical rotating clamping component 402 mounted on top of the vertical positioning component 401, with multiple smartwatch cases clamped and fixed inside the vertical rotating clamping component 402; a guide disk 403 rotatably connected to the center inside the vertical rotating clamping component 402; a vertical rotating rod 404 connected to the vertical rotating clamping component 402; a synchronous toothed belt 405 connected to the vertical rotating rod 404 via a synchronous pulley; and a piston powder spraying structure 406 connected to the synchronous toothed belt 405 via a synchronous pulley and positioned on top of the vertical rotating clamping component 402, wherein the piston powder spraying structure 406 performs powder spraying pretreatment on the surface of the clamped and fixed smartwatch cases.

[0067] The working principle is as follows: After the pre-processed smartwatch casing is manufactured, optical inspection is required to detect surface defects. At this time, the smartwatch casing is assembled inside the vertical rotating clamping assembly 402 using a mechanical gripper structure or manually. During each optical inspection, six smartwatch casings can be inspected simultaneously, improving the effectiveness of surface defect detection. After the smartwatch casing is clamped and fixed, the vertical adjustment assembly 401 is activated, moving the clamped smartwatch casing to the side of the optical inspection structure 30. The optical inspection structure 30 then automatically performs surface defect detection on the smartwatch casing, effectively improving the efficiency of surface defect detection. Meanwhile, before performing surface defect detection on the smartwatch casing, the force of rotating multiple vertical rotating clamping components 402 can simultaneously rotate the vertical rotating rod 404 connected to it, and drive the synchronous toothed belt 405 through the synchronous wheel to operate, so that the piston powder spraying structure 406 connected to the synchronous toothed belt 405 can operate, automatically completing the powder (for) conveying and spraying operation, converting strong specular reflection into diffuse reflection, so that the camera unit of optical detection can capture reflected light more stably, ensuring the accuracy of optical detection.

[0068] It should be noted that when the vertical rotating clamping assembly 402 is in operation, the guide disc 403 connected internally can automatically release (only one) the clamping and fixing state of a set of smartwatch shells as needed, making it convenient for staff or mechanical claw structures to replace or disassemble the smartwatch shells.

[0069] For details, please refer to the following: Figure 5 and Figure 6 The optical detection structure 30 includes a support frame 301, which is installed inside the detection housing 10 by screws. A horizontal slide rail system 302 is installed on the top of the support frame 301. An upper connector 304 is connected to the top of the horizontal slide rail system 302 via an electric slide block 303. A side metal plate 305 is connected to the upper connector 304. A first clamp 306 is installed on the side of the side metal plate 305. A supplementary light 307 is clamped and fixed on the inner side of the first clamp 306. The upper connector 304 and the side metal plate 305 are slidably connected to the side of a horizontal guide rail 308, which is installed on the side of the support frame 301.

[0070] In the intelligent inspection device for smartwatch casing production of the present invention, when performing surface defect inspection on the smartwatch casing, the horizontal slide rail system 302 is activated. The electric slide block 303 drives the upper connector 304 and the side metal plate 305 to move horizontally, adjusting the positions of the supplementary light 307 and the optical inspection module 3054 mounted on the side of the side metal plate 305. The horizontal guide rail 308 is designed to guide the horizontal movement of the upper connector 304 and the side metal plate 305, ensuring the stability of the supplementary light 307 and the optical inspection module 3054 during horizontal position adjustment.

[0071] For details, please refer to the following: Figure 6 A vertical guide rail 3051 is mounted on the side of the side metal plate 305 and is located on the side of the first clamp 306. A vertical slide block 3052 is slidably connected to the side of the vertical guide rail 3051. The vertical slide block 3052 is connected to the output end of the electric push rod 3053. The electric push rod 3053 is mounted on the side of the side metal plate 305. An optical detection module 3054 is mounted and fixed on the side of the vertical slide block 3052. A focusing lens group 3055 is mounted on the bottom of the optical detection module 3054 and is installed on the side of the vertical slide block 3052.

[0072] In the intelligent inspection device for smart watch casing production of the present invention, when performing surface defect inspection on the smart watch casing, the electric push rod 3053 can be activated to drive the vertical slide 3052 connected to the output end of the electric push rod 3053 to move up and down on the side of the vertical guide rail 3051, thereby driving the optical inspection module 3054 mounted on the side of the vertical slide 3052 to move up and down. By changing the distance between the optical inspection module 3054 and the focusing lens group 3055, automated optical inspection operation is achieved.

[0073] For details, please refer to the following: Figure 7 and Figure 8 The longitudinal adjustment assembly 401 includes a lower mounting base 4011, which is installed inside the detection housing 10. A longitudinal slide rail system 4012 is installed on the top of the lower mounting base 4011, and an upper base 4013 is installed on the top of the longitudinal slide rail system 4012. The upper base 4013 is slidably connected to the side of a guide metal block 4014, which is installed on the top of the lower mounting base 4011. A vertical rotation clamping assembly 402 is installed on the top of the upper base 4013.

[0074] In the intelligent inspection device for smart watch casing production of the present invention, when performing surface defect inspection on the smart watch casing, the upper base 4013 mounted on the top of the vertical slide rail system 4012 is moved vertically by activating the vertical slide rail system 4012, and the vertical rotating clamping assembly 402 mounted on the top of the upper base 4013 is moved vertically to the bottom of the optical inspection module 3054 and the focusing lens group 3055 to perform surface defect inspection.

[0075] For details, please refer to the following: Figure 9 , Figure 10 , Figure 11 and Figure 12 The vertical rotating clamping assembly 402 includes a protective bracket 4021, which is mounted on the top of the upper base 4013 by screws. A vertical drive source 4022 is installed inside the protective bracket 4021, and the output end of the vertical drive source 4022 is connected to a rotating disk 4023 rotatably connected to the top of the protective bracket 4021. An eccentric guide block 4024 is mounted on the eccentric part of the top of the rotating disk 4023 by screws. A side baffle 4025 is installed on one side inside the eccentric guide block 4024. A threaded rotating rod 4026 is threadedly connected inside the side baffle 4025 and passes through the side baffle 4025. A side positioning clamp 4027 is rotatably connected to the bottom of the threaded rotating rod 4026 and is slidably connected inside the eccentric guide block 4024.

[0076] In this design, a side compression clamp 40241 is slidably connected inside the eccentric guide block 4024. A side connecting rod 40242 extending to the outside is provided inside the side compression clamp 40241. The side connecting rod 40242 is installed and positioned inside the side compression clamp 40241 by a pin 40243. The side connecting rod 40242 is rotatably connected to the outside of the movable head 40244. The movable head 40244 is slidably connected to the inside of the upper guide block 40245. A piston powder spraying structure 406 is installed on the side of the protective bracket 4021.

[0077] In this design, the upper guide block 40245 is installed on the outer side of the top of the guide disk 403, the guide disk 403 is rotatably connected to the center of the top of the rotating disk 4023, and the movable head 40244 is movably disposed between the upper guide block 40245 and the guide disk 403. One side of the edge of the guide disk 403 is recessed inward, and the recessed part of the guide disk 403 forms an inner recess 4031. A vertical rotating rod 404 that penetrates the guide disk 403 is installed at the center of the top of the rotating disk 4023.

[0078] In the intelligent inspection device for manufacturing smart watch casings of the present invention, when performing surface defect inspection on the smart watch casing, the vertical drive source 4022 is activated to drive the rotating disk 4023 connected to the output end of the vertical drive source 4022, which in turn drives the eccentric guide block 4024 mounted at the eccentric top of the rotating disk 4023 to rotate. When the eccentric guide block 4024 rotates, the movable head 40244 connected to one side of its interior via the side connecting rod 40242 operates between the upper guide block 40245 and the guide disk 403. When the movable head 40244 moves to one side of the recessed portion 4031, it pulls the side connecting rod 40242 and the side compression clamp 40241 connected to the movable head 40244 to move, causing the side compression clamp 40241 to slide (outward) from the side of the side positioning clamp 4027, releasing the clamping and fixing state of the smartwatch casing between the side positioning clamp 4027 and the side compression clamp 40241. At the same time, by driving the rotating disk 4023 to rotate, the smartwatch casing inside the eccentric guide block 4024 can be easily moved to the bottom of the optical inspection module 3054 for optical surface defect detection.

[0079] It should be noted that the rotating threaded rotating rod 4026 can be rotated to drive the side positioning clamp 4027 connected to the bottom of the threaded rotating rod 4026 to extend and retract inside the eccentric guide block 4024, thereby changing the position of the side positioning clamp 4027 to adapt to smart watch cases of different sizes.

[0080] In addition, the depth of the side compression clamp 40241 outside the side connecting rod 40242 can be adjusted by pulling the side compression clamp 40241, and the position of the side compression clamp 40241 can be limited by installing the pin 40243, so as to change the position of the side compression clamp 40241 to adapt to smart watch cases of different sizes.

[0081] For details, please refer to the following: Figure 13 and Figure 14The piston powder spraying structure 406 includes an L-shaped metal frame 4061, which is mounted on one side of a protective bracket 4021 by screws. A movable rod 4062 is rotatably connected to one side of the L-shaped metal frame 4061. The movable rod 4062 is connected to the inner side of a synchronous toothed belt 405 via a synchronous pulley connected by an outer key. A rotating block 4063 is connected to the output end of the movable rod 4062. A telescopic arm 4064 is rotatably connected to the eccentric part inside the rotating block 4063. The telescopic arm 4064 is rotatably connected to the side of a bottom seat 4065. The bottom seat 4065 is slidably connected to one side inside a sealed container 4066. The synchronous toothed belt 405 is movably connected to the top of the L-shaped metal frame 4061. A vertical rotating rod 404 located on the side of the movable rod 4062 is rotatably connected inside the L-shaped metal frame 4061.

[0082] In this design, a powder inlet 40661 is connected to one side of the top of the sealed tank 4066, and a pusher piston 40662 is slidably connected inside the sealed tank 4066. The pusher piston 40662 is connected to the bottom seat 4065. A powder spray nozzle 40663 is connected to the bottom of the sealed tank 4066. The powder spray nozzle 40663 is installed inside the L-shaped metal frame 4061 and is located inside the synchronous toothed belt 405. It is used for powder pretreatment of the smartwatch casing.

[0083] In the intelligent inspection device for manufacturing smart watch casings of the present invention, when the rotating disk 4023 rotates, it can also drive the vertical rotating rod 404 connected to the rotating disk 4023 to rotate, and drive the synchronous toothed belt 405 to operate through the synchronous pulley, so that the inner side of the synchronous toothed belt 405 rotates through the synchronous pulley connected to the movable rod 4062. When the movable rod 4062 rotates, the rotating block 4063 installed on its top rotates, so that the telescopic arm 4064 rotatably connected at the eccentric part inside the rotating block 4063 operates, driving the bottom seat 4065 and the pusher piston 40662 rotatably connected to the bottom of the telescopic arm 4064 to telescopically move inside the sealed tank 4066, pushing the powder located inside the sealed tank 4066 to the inside of the powder spray nozzle 40663. At the same time, the powder input nozzle 40661 can transport the powder into the inside of the sealed tank 4066.

[0084] It should be noted that the powder inside the powder nozzle 40663 can be automatically sprayed onto the surface of the smartwatch casing at the bottom through the internal module of the powder nozzle 40663, thereby reducing the mirror reflection on the surface of the smartwatch casing.

[0085] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
