Technical Field
[0001] This utility model relates to the field of precision machinery manufacturing, and in particular to a device for detecting surface defects after watch case grinding and polishing. Background Technology
[0002] A surface defect detection device for watch cases is a specialized instrument designed to inspect the surface of precision metal products such as watch cases for any defects after polishing and grinding. This device is widely used in high-end watchmaking and other industries requiring high-precision surface treatment to ensure that the product's appearance meets stringent standards.
[0003] In the high-end watch manufacturing and other precision metal product processing industries, the detection of surface defects after watch case polishing is a key step in ensuring product quality. Although existing watch case polishing surface defect detection devices can achieve high-precision detection, dust and other tiny particles tend to accumulate inside the detection device during long-term use. Dust accumulation not only affects the clarity of the optical imaging system but also interferes with the normal operation of the sensor and detection equipment, thereby reducing the accuracy and reliability of watch case surface defect detection.
[0004] To address the aforementioned issues, it is necessary to design a dustproof device for detecting surface defects after the watch case has been polished. Utility Model Content
[0005] To overcome the drawback that dust and other tiny particles tend to accumulate inside the detection device during prolonged use, affecting the clarity of the optical imaging system, this utility model provides a surface defect detection device for watch cases after polishing.
[0006] The technical solution of this utility model is as follows: A surface defect detection device after watch case grinding and polishing includes a base, a conveyor belt, a servo motor, a defect detection device and a dustproof component. A conveyor belt is installed on the upper side of the base, a servo motor is installed on the right side of the base, the output shaft of the servo motor passes through the base and is fixedly connected to the rotating shaft of the conveyor belt, a defect detection device is installed in the middle of the base, and a dustproof component is provided on the base.
[0007] In one embodiment, the dustproof assembly includes a mounting base, a bidirectional screw, a bidirectional motor, a sliding plate, a guide frame, a baffle, and a sensor. The mounting base is symmetrically connected to the left and right sides. A bidirectional motor is mounted in the middle of each of the two mounting bases. A bidirectional screw is connected to the output shaft of each of the two bidirectional motors. A sliding plate is slidably connected to each bidirectional screw. A guide frame is symmetrically connected to the front and rear of the outer side of the defect detection equipment. Each sliding plate slides in cooperation with the corresponding guide frame. A baffle is connected to each sliding plate, and a sensor is mounted on each baffle.
[0008] In one embodiment, the device further includes a support plate, a placement tray, gears, and a rack. Multiple support plates are evenly spaced on the conveyor belt, and a placement tray is rotatably connected to each support plate. A gear is connected to the center of each placement tray. A rack is connected to the front of the inside of the defect detection device, and multiple gears mesh with the rack.
[0009] In one embodiment, a protective shell is also included, with the protective shell connected to the right side of the base and located outside the servo motor.
[0010] In one embodiment, the base has multiple mounting holes.
[0011] In one embodiment, multiple placement trays are arranged horizontally.
[0012] The beneficial effects of this utility model are as follows: By setting up a bidirectional screw, a bidirectional motor, a sliding plate, a guide frame, a baffle, and a sensor, the two bidirectional motors can drive the bidirectional screw connected to their two output shafts to rotate.

Detailed Implementation
[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0020] Example: A device for detecting surface defects after watch case polishing, such as... Figures 1-5 As shown, the device includes a base 1, a conveyor belt 2, a servo motor 201, a protective shell 202, a defect detection device 3, a support plate 11, a placement tray 12, a gear 13, a rack 14, and a dustproof assembly. The base 1 has multiple mounting holes. The conveyor belt 2 is mounted on the upper side of the base 1. The servo motor 201 is mounted on the right side of the base 1. The output shaft of the servo motor 201 passes through the base 1 and is fixedly connected to the shaft of the conveyor belt 2. The protective shell 202 is connected to the right side of the base 1 and is located outside the servo motor 201. The protective shell 202 protects the servo motor from external contaminants. The machine 201 is protected. A defect detection device 3 is installed in the middle of the base 1. The defect detection device 3 can perform high-precision defect detection on the surface of the watch case. Multiple support plates 11 are evenly spaced on the conveyor belt 2. Each support plate 11 is rotatably connected to a placement tray 12. The multiple placement trays 12 are arranged horizontally. The placement trays 12 are used to place the watch cases that need to be defect-detected. A gear 13 is connected to the middle of each placement tray 12. The gear 13 cooperates with the rack 14 so that the gear 13 can move when the watch case enters the detection area of the defect detection device 3. The movable plate 12 and the watch case rotate to ensure that the surface of the watch case is inspected from multiple angles. A rack 14 is connected to the front of the inside of the defect detection device 3, and multiple gears 13 mesh with the rack 14. A dustproof assembly is provided on the base 1. The dustproof assembly includes a mounting base 4, a bidirectional screw 5, a bidirectional motor 6, a sliding plate 7, a guide frame 8, a baffle 9, and a sensor 10. The mounting base 1 is symmetrically connected to the left and right sides. The mounting base 4 is used to support the bidirectional motor 6 and the bidirectional screw 5. The bidirectional motor 6 is installed in the middle of both mounting bases 4. The output shafts of the two bidirectional motors 6 are... Each of the two sides is connected to a bidirectional screw 5, and a sliding plate 7 is slidably connected to each bidirectional screw 5. Guide frames 8 are symmetrically connected to the front and rear of the outer side of the defect detection device 3. Each sliding plate 7 is slidably engaged with the corresponding guide frame 8. Each sliding plate 7 is connected to a baffle 9. The baffle 9 can facilitate the entry of the watch case into the detection area of the defect detection device 3 and prevent dust and other impurities from entering the interior of the defect detection device 3. Each baffle 9 is equipped with a sensor 10. The sensor 10 is used to detect the presence or absence of the watch case and trigger the start or stop of the bidirectional motor 6.
[0021] After the watch case has been polished, when this device is needed to detect defects on the surface of the watch case, the operator first activates multiple sensors 10 and the defect detection device 3 to ensure that they are in working order. Then, the operator starts the servo motor 201. The output shaft of the servo motor 201 drives the conveyor belt 2 to rotate, and the conveyor belt 2 transports all the components on it to the left. Subsequently, the operator places the watch case to be inspected on the placement tray 12, which then transports the watch case to the left. During the transport of the watch case, when the two sensors 10 on the right detect the watch case, they control the bidirectional motor 6 on the right to start. The output shafts at both ends of the bidirectional motor 6 on the right drive the two bidirectional screws 5 on the right to rotate respectively. The two bidirectional screws 5 on the right drive the sliding plates 7 on them to move outward along the corresponding guide frames 8. The sliding plates 7 drive the corresponding baffles 9 and sensors 10 to move outward. When the two baffles 9 on the right move to the appropriate position, the conveyor belt 2 continues to transport all the components on it to the left. When the case is completely inside the defect detection equipment 3, the two sensors 10 on the right control the bidirectional motor 6 on the right to rotate in the opposite direction. The output shafts at both ends of the bidirectional motor 6 on the right drive the two bidirectional screws 5 on the right to rotate in the opposite direction. The two bidirectional screws 5 on the right drive the sliding plates 7 on them to move inward along the corresponding guide frames 8. The sliding plates 7 drive the corresponding baffles 9 and sensors 10 to move inward until the two baffles 9 and sensors 10 on the right move inward. After returning to the initial position and fitting tightly, the two sensors 10 on the right side control the right bidirectional motor 6 to shut off. Subsequently, the defect detection device 3 begins to detect defects on the surface of the watch case. At the same time, the gear 13 contacts the rack 14 and rotates along the rack 14. During the rotation of the gear 13, the gear 13 drives the placement plate 12 and the watch case to rotate for multi-angle detection. When the watch case approaches the two sensors 10 on the left side, the two sensors 10 on the left side control the left bidirectional motor 6 to start. The output shafts at both ends of the left bidirectional motor 6 drive the two left bidirectional screws 5 to rotate. The two left bidirectional screws 5 drive the sliding plates 7 on them to move outward along the corresponding guide frames 8. The sliding plates 7 drive the corresponding baffles 9 and sensors 1. The device moves outwards until the corresponding baffle 9 and sensor 10 reach the appropriate position. At this point, the defect-detected watch case continues to be conveyed to the left by conveyor belt 2 until it leaves the defect detection device 3. When the two sensors 10 on the left no longer detect the watch case, they control the left bidirectional motor 6 to rotate in the opposite direction. The output shafts at both ends of the two bidirectional motors 6 drive the sliding plates 7 on them to move inwards. The sliding plates 7 drive the corresponding baffle 9 and sensor 10 to move inwards along the corresponding guide frame 8 until the two baffles 9 and sensors 10 on the left move to their initial positions and fit tightly together. The two sensors 10 on the left then control the left bidirectional motor 6 to turn off. The above steps are repeated until all watch cases have completed defect detection.Then, the servo motor 201, the defect detection device 3, and multiple sensors 10 are turned off in sequence.
