[0002] As a common accessory and time management tool, watches are loved by consumers. In order to ensure that consumers purchase high-quality watch products, it is particularly important to test and evaluate the quality of watches.

[0028] A fixing ring 13 is inserted and installed on the inner surface of the rotating gear 11. The fixing ring 13 is composed of two semi-arc-shaped ring bodies. The middle parts of both ends of the outer ring surface of the fixing ring 13 are fixed with stop blocks 1301 in a convex shape. The stop blocks 1301 are clamped into the stop opening 1101.

When the watch is removed after inspection, the shape of the inner ring surface of the memory cotton sleeve 1302 can be used to check whether there are defects on the outer ring surface of the watch.

[0029] The control computer 3 is internally provided with a database, a combination module, an analysis module, a control module and a signal module; The database is used to store defect-free surface images of qualified watches of various types, and preset each surface image as a detection standard reference image; The specific analysis is as follows: filter out qualified watches of various types, and take photos of the surface images of qualified watches and store them in the database, which are preset as the reference images of the inspection standards; The signal module is used to receive the real-time watch surface data information obtained by each detection mechanism, and transmit the data information to the corresponding processing module, and the processing module generates various operation instructions and transmits them to the corresponding execution mechanism; The specific analysis is as follows: the image data captured in real time by the first detection camera 401 and the second detection camera 403 during the watch detection process is received by the signal module, and the electrical signal data generated by the tactile sensor 5 is received at the same time, and the image data and the electrical signal data are transmitted to the combination module and the analysis module respectively, and the qualified or unqualified instruction of the watch surface detection is obtained after being processed by the analysis module, and the execution mechanism is controlled to perform the corresponding operation based on the qualified or unqualified instruction, and the operation signal is transmitted by the signal module; The combination module generates a combination of watch surface images based on the real-time watch surface data information obtained by the detection mechanism, obtains a detection image and transmits it to the analysis module; The specific analysis is as follows: the received image data are arranged in sequence according to the order of recording to form a surface image of the watch, and the detection image formed by the surface image is transmitted to the analysis module; The analysis module is used to compare the received test image with the monitoring standard reference image. If the comparison is successful, a first-level qualified signal is generated. If the comparison fails, a failed signal is generated. A watch surface defect detection failed instruction is generated based on the failed signal. At the same time, based on the real-time watch surface data information obtained by the testing agency, the electrical signal change data contained in the data is extracted, and whether there is a defect on the watch surface is determined by the change state. If there is no defect, a second-level qualified signal is generated. A watch surface defect detection qualified instruction is generated based on the first and second-level qualified signals. The specific analysis is as follows: the received test image is compared with the test standard reference image. If the test image and the test standard reference image are exactly the same, the comparison is successful and a first-level qualified signal is generated. If there is an error between the test image and the test standard reference image, the comparison fails and a failed signal is generated. The corresponding failed instruction is obtained based on the failed signal. The unqualified instruction specifically includes: S1, controlling the prompt light 301 to light red, indicating that the watch surface has defects and the detection is unqualified; S2, transmitting the control signal to the controller 404, and the controller 404 controls the first detection camera 401, the second detection camera 403 and the line light 402 to stop running, and controls the tactile sensor 5 to stop running; S3, control the second electric push rod 6 to retract, control the first electric push rod 103 to expand, drive the tactile sensor 5 and the assembly plate 4 away from the watch, and drive the detection cavity 2 away from the watch, and expose the watch from the detection cavity 2, and then take out the unqualified watch; Analyze the received electrical signal data generated by the tactile sensor 5 to generate a corresponding electrical signal data fluctuation line. If the fluctuation line is in a stable linear state, it indicates that there is no defect on the watch surface and a secondary qualified signal is generated. If the fluctuation line is in an undulating linear state, it indicates that there is a defect on the watch surface and a non-qualified signal is generated. Based on the primary and secondary qualified signals, a qualified instruction for the watch surface defect detection is jointly generated. The qualified instruction specifically includes: S1, controlling the prompt light 301 to light green, indicating that there is no defect on the watch surface and the test is qualified; S2-S3 repeat the above unqualified instruction operation process; The control module controls each actuator to perform corresponding operations based on the instructions generated by the analysis module, and the signal module transmits the control signal.

[0030] When the present invention is used, the fixing ring 13 can be firstly disassembled and sleeved on the outer ring surface of the watch to be detected. At this time, the memory foam sleeve 1302 can be memorized according to the shape of the outer ring surface of the watch, and the fixing ring 13 holding the watch is inserted into the rotating gear 11. The fixing ring 13 is fixed by the mutual engagement of the limit block 1301 and the limit opening 1101. After the watch is installed, the first electric push rod 103 can be controlled to retract and drive the detection cavity 2 to move toward the direction of the watch until the watch is covered; When the watch is covered by the detection cavity 2, the second electric push rod 6 can be started to start the operation to drive the assembly plate 4 and the tactile sensor 5 toward the watch surface until the friction rod 501 contacts the watch surface. At this time, the controller 404 can control the line lamp 402 to start linear lighting on the watch surface, and control the first detection camera 401 to start at the same time. In this case, the detection personnel can control the transmission rod 901 to rotate to drive the transmission gear 9 to rotate. When the transmission gear 9 is in a rotating state, the engagement transmission of the transmission belt 12 can synchronously drive the rotating gear 11 to rotate, and then the rotation of the rotating gear 11 drives the watch clamped in the fixed ring 13 to rotate. During the rotation of the watch, the first detection camera 401 can fully record the front image of the lower surface of the watch. After the front image is recorded, the first detection camera 401 can be controlled to stop running and then the second detection camera 403 can be started. The side image of the lower surface of the watch is fully recorded by the second detection camera 403, thereby obtaining a comprehensive detection image of the lower surface of the watch. Secondly, when the first detection camera 401 and the second detection camera 403 obtain a comprehensive detection image of the lower surface of the watch, the friction rod 501 in contact with the upper surface of the watch will complete the comprehensive friction contact with the upper surface of the watch as the watch rotates. Since the tactile sensor 5 is a triboelectric tactile sensor, the contact between the friction rod 501 and the upper surface of the watch generates electric charges, causing changes in electrical signals, thereby obtaining comprehensive detection electrical signal data of the upper surface of the watch; After the preliminary detection data of the upper and lower surfaces of the watch are obtained, the tactile sensor 5, the first detection camera 401, the second detection camera 403 and the line light 402 can be controlled to stop running, and the second electric push rod 6 can be controlled to retract to drive the tactile sensor 5 and the assembly plate 4 away from the position of the watch. At the same time, the first electric push rod 103 can be controlled to expand to drive the detection cavity 2 to move away from the watch. When the detection cavity 2 and the watch are separated from each other, the detection personnel can turn the control rod 8 to drive the cover plate 1102 to flip, thereby driving the watch to flip. After the watch is flipped, the above-mentioned acquisition operation of the comprehensive detection image of the lower surface of the watch and the comprehensive detection electrical signal data of the upper surface of the watch can be repeated to achieve the acquisition of the comprehensive detection image of the upper surface of the watch and the comprehensive detection electrical signal data of the lower surface of the watch, so as to achieve the effect of alternating mixed detection; When all the detection data of the watch surface are acquired, they can be transmitted to the control computer 3 for data analysis and processing, and the detection result of the watch is obtained based on the data analysis and processing to determine whether there are defects on the watch surface, and at the same time, corresponding operation instructions are executed based on the detection result.
