[0099] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0100] Please refer to Figure 1 , the embodiment of the present invention provides a crown automatic testing machine, and its structural composition includes multiple key components such as a machine base 1, a carrier 2, a probe module 3, a drawer-type support module 4, a pressing module 5, and a rotating pressing test module 6. The structural features and functional roles of each component will be elaborated in detail below:

[0101] The drawer-type support module 4 is designed with a dedicated placement opening 7, and the size and shape of the placement opening 7 are adapted to the carrier 2 to ensure that the carrier 2 can be stably placed therein, providing a basic support for subsequent testing operations.

[0102] The drawer-type support module 4 is arranged on the machine base 1 through a precise sliding mechanism and has the ability to slide smoothly in the front-rear direction. This design aims to optimize the loading and unloading process of the carrier 2, enabling the operator to conveniently and efficiently complete the loading and unloading of the carrier 2, thereby enhancing the coherence and efficiency of the overall testing process.

[0103] The carrier 2, as the device for carrying and fixing the crown, has a structural design that fully considers the shape characteristics and testing requirements of the crown, ensuring the stability of the crown during the testing process and preventing testing errors caused by shaking or displacement.

[0104] The probe module 3 is installed on the machine base 1 and is precisely positioned in the lower area of the drawer-type support module 4. This module is electrically connected to the crown placed on the carrier 2 through the placement opening 7, providing the necessary electrical interface for various performance tests of the crown.

[0105] The pressing module 5 is also arranged on the machine base 1 and is located directly above the carrier 2. By applying an appropriate downward pressure, this module ensures a stable and reliable electrical connection between the crown and the probe module 3, thereby guaranteeing the accuracy and consistency of the test data.

[0106] The rotary pressing test module 6 is also installed on the machine base 1 and is located above the carrier 2. This module has the function of rotating and pressing the crown, can simulate various operating states of the crown during actual use, and cooperates with the probe module 3 to conduct a comprehensive and detailed test on the crown.

[0107] The crown automatic testing machine provided by the embodiment of the present invention realizes the efficient and precise testing of the crown through a highly integrated automated design. Specifically, this testing machine makes full use of the sliding characteristics of the drawer-type support module 4, optimizes the loading and unloading process of the carrier 2, and significantly improves the testing efficiency. At the same time, the coordinated work of the probe module 3 and the pressing module 5 ensures a stable electrical connection between the crown and the probe, enhancing the reliability and consistency of the test results. In addition, the introduction of the rotary pressing test module 6 enables the automatic completion of the rotation and pressing tests of the crown, not only reducing the labor intensity of the operator but also avoiding testing errors caused by human factors. In summary, the crown automatic testing machine of the present invention shows significant advantages in improving testing efficiency, ensuring testing quality, reducing labor costs, and increasing the automation level of the production line, and has important practical value and broad promotion prospects for the watch manufacturing industry and the precision instrument testing field.

[0108] Please refer to Figures 2-3 , in an implementation manner of this embodiment, the crown automatic testing machine further adds a key component, the shielding cover 8, on the basis of the original structure.

[0109] The shielding cover 8 is set on the base 1 in a stable installation manner. It has a clever design and comprehensive functions, and can completely cover core components such as the vehicle 2, the probe module 3, the drawer-type support module 4, the pressing module 5, and the rotating pressing test module 6 in its internal space. This design not only provides physical protection for these precision components to prevent accidental collision or damage by external objects, but also plays an important role in electromagnetic environment control. By shielding external electromagnetic interference, it creates a stable and pure electromagnetic environment for the crown test process, effectively avoiding test data distortion or test result deviation caused by external electromagnetic signal interference, thus ensuring the accuracy and reliability of the test results.

[0110] The shielding cover 8 is carefully provided with an opening 9. The size and position of the opening 9 are precisely calculated and optimized, which not only meet the basic requirements of the test operation, but also minimize the risk of electromagnetic leakage. In specific applications, the opening 9 provides a necessary space channel for the sliding operation of the drawer-type support module 4, enabling the drawer-type support module 4 to smoothly slide in the front-rear direction without destroying the overall shielding effect of the shielding cover 8.

[0111] During the sliding process of the drawer-type support module 4, its position change is dynamically associated with the opening and closing state of the opening 9. When the drawer-type support module 4 slides to a specific position, it can exactly close the opening 9. At this time, a relatively closed electromagnetic space is formed inside the shielding cover 8, further enhancing the shielding effect and providing a more stable and reliable electromagnetic environment for the test process. When it is necessary to place or remove the vehicle 2 or perform other related operations, the drawer-type support module 4 can slide in the front-rear direction to open the opening 9, facilitating the operator to smoothly complete various test tasks.

[0112] In summary, the setting of the shielding cover 8 is an important innovation point and improvement point of the crown automatic testing machine in this embodiment. By adding the shielding cover 8, the testing machine has been significantly improved in terms of electromagnetic environment control, physical protection, and operation convenience.

[0113] Please refer to Figures 4-5 , in an implementation manner of this embodiment, the structural design of the drawer-type support module 4 is ingenious. It is precisely composed of multiple key components such as a push-pull plate 401, a sliding component 402, a support plate 403, and a buffer component 404. The following will elaborate on the structural characteristics and functional roles of each component in detail:

[0114] The push-pull plate 401, as an important operating component of the drawer-type support module 4, is installed on the base 1 in a stable and flexible manner through the sliding component 402. Under the precise guidance of the sliding component 402, the push-pull plate 401 can slide smoothly along the front-back direction. This design not only provides a convenient operating experience for the operator but also ensures the stability and reliability of the drawer-type support module 4 during the sliding process, effectively avoiding test interruptions or equipment damage caused by poor sliding or jamming.

[0115] The support plate 403, as a key component for carrying the carrier 2, is installed on the base 1 in a clever way through the buffer component 404. The placement opening 7 is precisely set on the support plate 403, and its size and shape perfectly match the carrier 2, ensuring that the carrier 2 can be stably placed therein, providing a solid foundation support for subsequent test operations.

[0116] The buffer component 404, as the core buffer component in the drawer-type support module 4, fully considers various mechanical factors during the test process. This component can provide excellent buffering performance for the support plate 403 in the up-down direction, effectively absorbing and dispersing the impact force generated by the pressing module 5 pressing down. This design not only protects the support plate 403 and the carrier 2 thereon from damage but also ensures the stability of the electrical connection between the crown and the probe module 3, thereby improving the accuracy and reliability of the test results.

[0117] In a specific application, when the pressing module 5 performs a pressing operation, the buffer component 404 can quickly respond and play its buffering role, enabling the support plate 403 to remain stable when receiving the downward pressure, avoiding the shaking of the carrier 2 or the loosening of the electrical connection between the crown and the probe module 3 caused by excessive pressing. At the same time, the buffering performance of the buffer component 404 can also effectively reduce the noise and vibration generated by the pressing operation, creating a quieter and more stable working environment for the test process.

[0118] In summary, the drawer-type support module 4 realizes the stable loading and convenient picking and placing of the carrier 2 through the coordinated work of components such as the push-pull plate 401, the sliding component 402, the support plate 403, and the buffer component 404, while ensuring the stability of the electrical connection between the crown and the probe module 3. This design not only improves the efficiency and accuracy of the test process but also provides a strong guarantee for the long-term stable operation of the testing machine.

[0119] Please refer to again Figures 4-5 , in an implementation manner of this embodiment, the drawer-type support module 4 further adds a key component, the sensor 405, on the basis of the original structure.

[0120] The sensor 405 is precisely set on the support plate 403, and its position is carefully designed and optimized to ensure accurate and efficient execution of the detection task. The core function of this sensor 405 is to detect whether the crown is correctly placed on the carrier 2, and this function is crucial for the smooth progress of the entire testing process.

[0121] In practical applications, when the operator places the crown on the carrier 2, the sensor 405 will immediately start the detection program. It comprehensively and meticulously detects the position, posture, and contact state of the crown with the carrier 2 through a series of advanced sensing technologies, such as optical sensing.

[0122] If the detection result shows that the crown has been correctly placed on the carrier 2, the sensor 405 will send a confirmation signal to the control system of the testing machine, indicating that the crown is ready and the subsequent testing process can begin. This signal not only provides an important basis for the automated operation of the testing machine but also ensures the continuity and stability of the testing process.

[0123] On the contrary, if the detection result shows that the crown is not correctly placed on the carrier 2, such as there are problems like position deviation or incorrect posture, the sensor 405 will immediately send a warning signal to the control system. This signal will trigger the corresponding protection mechanisms of the testing machine, such as stopping the testing process, issuing an alarm prompt, or requiring the operator to readjust the position of the crown, etc., to avoid testing errors or equipment damage caused by improper placement of the crown.

[0124] In summary, the setting of the sensor 405 is an important innovation point and improvement point of the drawer - type support module 4 in this embodiment. By adding the sensor 405, the testing machine has achieved automation and intelligence in crown placement detection, effectively improving the accuracy and reliability of the testing process.

[0125] Please refer to Figures 6-7 , in an implementation manner of this embodiment, the structure of the carrier 2 is finely designed and fully functional. It is organically composed of key components such as a carrier board 201, a BTB flip - cover elastic pressing module 202, and a spring - needle module 203. The following will elaborate in detail on the structural characteristics and functional roles of each component:

[0126] The carrier board 201, as the basic load - bearing component of the carrier 2, is carefully provided with a DUT positioning groove 204 and a BTB positioning groove 205. The design of these two positioning grooves fully considers the shape characteristics and testing requirements of the crown and its BTB board, providing a reliable guarantee for the precise positioning and stable loading of the crown and the BTB board.

[0127] The DUT positioning groove 204 is designed specifically to carry and position the crown. Inside the DUT positioning groove 204, positioning pins 206 are provided that precisely correspond to the grooves on the crown. The size, shape, and position of these positioning pins 206 have been precisely calculated and optimized to ensure that when the crown is placed in the DUT positioning groove 204, it can be quickly and accurately positioned, preventing the crown from shaking or displacing during the test, thus ensuring the accuracy and consistency of the test data.

[0128] The BTB positioning groove 205 is used to carry and position the BTB board of the crown. As a key component for the electrical connection between the crown and the test equipment, the accuracy of its positioning directly affects the reliability of the test results. Therefore, the design of the BTB positioning groove 205 fully considers factors such as the shape, size, and installation direction of the BTB board to ensure that the BTB board can be stably placed therein, providing a stable foundation for subsequent electrical connections.

[0129] The shrapnel pin module 203 is cleverly arranged within the BTB positioning groove 205, and its function is to establish an electrical connection with the BTB board located within the BTB positioning groove 205. The shrapnel pin module 203 adopts advanced elastic contact technology to ensure a stable and reliable electrical connection with the BTB board, providing a necessary electrical signal transmission channel for various performance tests of the crown.

[0130] The BTB flip cover elastic pressing module 202 is arranged on the carrier plate 201, with a clever design and practical function. This module can perform an elastic pressing operation on the BTB board located within the BTB positioning groove 205, enabling a more tight and stable electrical connection between the BTB board and the shrapnel pin module 203. This design not only enhances the reliability of the electrical connection but also effectively avoids problems such as test errors or signal interruptions caused by poor contact.

[0131] In practical applications, when the crown and its BTB board are correctly placed on the carrier 2, the BTB flip cover elastic pressing module 202 will initiate a pressing operation to form a stable electrical connection between the BTB board and the shrapnel pin module 203. Subsequently, the testing machine can send test signals to the crown through the shrapnel pin module 203 and receive the response signals returned by the crown, thereby achieving a comprehensive and accurate test of the various performances of the crown.

[0132] In summary, through the coordinated work of components such as the carrier plate 201, the BTB flip cover elastic pressing module 202, and the shrapnel pin module 203, the carrier 2 achieves precise positioning, stable carrying, and stable electrical connection of the crown and its BTB board.

[0133] Please refer to again Figures 6-7, in an implementation manner of this embodiment, the vehicle 2 is further provided with a DUT blocking module 207 and a preloading module 208 on the basis of the original structure. The design and integration of these two modules significantly improve the functionality and practicality of the vehicle 2.

[0134] The DUT blocking module 207 is carefully arranged on the carrier board 201, and its core function is to precisely block the crown located in the DUT positioning groove 204. This module consists of two key components, a first linkage block 2071 and a blocking block 2072, which achieve synchronous movement through precise mechanical connection.

[0135] The first linkage block 2071 serves as the power input end of the DUT blocking module 207. When subjected to an external driving force, the first linkage block 2071 can quickly respond and generate a corresponding displacement.

[0136] The blocking block 2072 is directly connected to the first linkage block 2071 and moves synchronously under the drive of the first linkage block 2071. During the movement, the blocking block 2072 can precisely enter or exit the DUT positioning groove 204, thereby achieving the blocking or release of the crown. It should be noted that there is a small gap between the blocking block 2072 and the crown. This design not only ensures that the blocking block 2072 will not cause physical damage to the crown when blocking it, but also avoids the deformation or functional failure of the crown caused by excessive extrusion.

[0137] In practical applications, the DUT blocking module 207 can be flexibly controlled according to the requirements of the test process. After the crown is placed in the DUT positioning groove 204, the blocking block 2072 is driven into the DUT positioning groove 204 by driving the first linkage block 2071, thereby achieving the firm blocking of the crown and preventing it from accidentally moving during subsequent tests. After the test is completed, the blocking block 2072 is driven out of the DUT positioning groove 204 by driving the first linkage block 2071 to release the crown for picking and placing operations.

[0138] The preloading module 208 is also arranged on the carrier board 201, and its function is to preload the BTB board located in the BTB positioning groove 205. This module consists of two core components, a second linkage block 2081 and a preloading block 2082, which work together through a precise mechanical structure.

[0139] The second linkage block 2081 serves as the power input end of the preloading module 208. When subjected to an external driving force, the second linkage block 2081 can quickly respond and generate a corresponding displacement.

[0140] The preloading block 2082 is directly connected to the second linkage block 2081 and moves synchronously under the drive of the second linkage block 2081. During the movement, the preloading block 2082 can accurately enter or exit the BTB positioning slot 205, thereby realizing the pressing down or releasing of the BTB board. The downward pressure of the preloading block 2082 is precisely calculated and adjusted, which can not only ensure a stable and reliable electrical connection between the BTB board and the spring needle module 203, but also prevent over-extrusion of the BTB board and damage to its internal structure.

[0141] The preloading module 208 plays a crucial role during the testing process. After the BTB board is placed in the BTB positioning slot 205, the second linkage block 2081 is driven to make the preloading block 2082 enter the BTB positioning slot 205 and perform a preloading operation on the BTB board, thereby ensuring good electrical contact between the BTB board and the spring needle module 203. This preloading operation not only improves the stability and reliability of the electrical connection, but also effectively avoids problems such as test errors or signal interruptions caused by poor contact. After the test is completed, the second linkage block 2081 is driven again to make the preloading block 2082 exit the BTB positioning slot 205 and release the BTB board for subsequent operations.

[0142] In summary, the addition of the DUT blocking module 207 and the preloading module 208 are important innovation points and improvement points of the carrier 2 in this embodiment. Through precise mechanical structures and flexible control methods, these two modules achieve precise positioning, stable loading, and stable electrical connection of the crown and the BTB board.

[0143] Please refer to Figure 8 , in an implementation manner of this embodiment, the design of the probe module 3 fully reflects the characteristics of precision and efficiency. It is precisely composed of three core components: the probe base 301, the probe group 302, and the negative pressure suction cup 303. The following will elaborate in detail on the structural characteristics, functional roles, and collaborative working principles of each component:

[0144] The probe base 301, as the basic bearing component of the probe module 3, is stably set on the machine base 1. Its structural design fully considers the installation requirements and movement characteristics of the probe group 302 and the negative pressure suction cup 303, providing a reliable guarantee for the precise positioning and stable operation of the subsequent components. The material and manufacturing process of the probe base 301 are carefully selected and optimized to ensure that it has sufficient rigidity and stability to withstand various stresses and vibrations generated by the probe group 302 and the negative pressure suction cup 303 during the testing process.

[0145] The probe group 302 is precisely set on the probe base 301, and its core function is to achieve electrical connection with the spring needle module 203 located on the vehicle 2. Parameters such as the number of probes, arrangement pattern, and contact pressure of the probe group 302 are precisely calculated and adjusted to ensure a stable and reliable electrical connection with the spring needle module 203. During the testing process, the probe group 302 can accurately transmit the test signals of the testing machine to the crown and receive the response signals returned by the crown, thereby achieving a comprehensive and accurate test of various performances of the crown.

[0146] The negative pressure suction cup 303 is also set on the probe base 301, but its position is distinguished from that of the probe group 302 and is specifically used for adsorbing and fixing the crown located in the DUT positioning groove 204. To achieve this function, a suction cup through-hole 209 through which the negative pressure suction cup 303 can pass is specifically provided in the DUT positioning groove 204. The negative pressure suction cup 303 can tightly adsorb on the surface of the crown through the internal negative pressure effect, thereby achieving the firm fixation of the crown. This design not only prevents the crown from moving or falling off due to vibration or external force during the testing process, but also ensures the stability and reliability of the electrical connection between the probe group 302 and the crown.

[0147] In summary, the probe module 3 realizes the firm fixation, precise testing, and efficient picking and placing of the crown through the coordinated work of components such as the probe base 301, the probe group 302, and the negative pressure suction cup 303.

[0148] Please refer to Figure 9 , in an implementation manner of this embodiment, the overall structural design of the pressing module 5 is precise and its functions are complete. It is scientifically composed of core components such as a bracket 501, a first mounting plate 502, a driving mechanism 503, and a pressing rod 504. The following will elaborate in detail and formally on the specific structural features, functional roles, and coordinated working principles of each component:

[0149] The bracket 501, as the basic supporting component of the pressing module 5, is firmly installed on the machine base 1. Its design fully considers the stability and load-bearing capacity of the overall structure. It is made of high-strength materials and undergoes precise processing and assembly to ensure that it can withstand the huge force generated when the pressing rod 504 presses down during the testing process without deformation or damage. The shape and size of the bracket 501 are carefully calculated and optimized, which not only meet the installation requirements of the pressing module 5 but also provide sufficient space for the arrangement and movement of subsequent components.

[0150] The first mounting plate 502, as the main moving part of the pressing module 5, is arranged on the bracket 501 in a liftable manner through the driving mechanism 503. The material and manufacturing process of the first mounting plate 502 have been strictly screened and optimized to ensure that it has sufficient rigidity and strength to withstand the weight of the pressing rod 504 and various stresses generated during the downward pressing process. At the same time, the surface of the first mounting plate 502 has been precisely machined and processed to ensure a firm and reliable connection between it and the pressing rod 504, without loosening or falling off.

[0151] The driving mechanism 503, as the power source of the pressing module 5, is responsible for driving the first mounting plate 502 to perform lifting motion. This mechanism adopts advanced driving technology and a precise transmission system, enabling the smooth and rapid lifting of the first mounting plate 502. The control precision and response speed of the driving mechanism 503 have been strictly tested and adjusted to ensure that it can meet the high-precision requirements for pressing force and speed during the test process. In addition, the driving mechanism 503 also has safety functions such as overload protection and position feedback to ensure that abnormal situations can be detected and processed in a timely manner during the test process, protecting the safety of the test equipment and personnel.

[0152] The pressing rods 504, as the execution parts of the pressing module 5, are precisely arranged on the first mounting plate 502. There are a total of six pressing rods 504, and the shape, size, and material of each pressing rod 504 have been carefully designed and selected to ensure that it has sufficient strength and stiffness to withstand the huge acting force generated during the downward pressing process without bending or breaking. Four of the pressing rods 504 correspond to the four corners of the carrier 2. When the first mounting plate 502 descends, these four pressing rods 504 can first contact the four corners of the carrier 2 and perform preliminary downward pressing and positioning on it. The remaining two pressing rods 504 are correspondingly located at the two corners of the BTB flip cover elastic pressing module 202. When the first mounting plate 502 continues to descend, these two pressing rods 504 can perform further downward pressing operations on the BTB flip cover elastic pressing module 202 to ensure its close fit and stable connection with the carrier 2.

[0153] In practical applications, when the test process requires downward pressing on the carrier 2, the driving mechanism 503 starts to operate and drives the first mounting plate 502 to descend. As the first mounting plate 502 descends, the six pressing rods 504 also descend synchronously. First, the four pressing rods 504 corresponding to the four corners of the carrier 2 contact the carrier 2 and perform preliminary downward pressing and positioning to ensure that the carrier 2 does not shake or displace during the test process. Subsequently, when the first mounting plate 502 continues to descend, the remaining two pressing rods 504 corresponding to the two corners of the BTB flip cover elastic pressing module 202 also perform downward pressing operations on it to ensure the close fit and stable connection between the BTB flip cover elastic pressing module 202 and the carrier 2.

[0154] After the pressing operation is completed, the driving mechanism 503 drives the first mounting plate 502 to rise and drives the six pressing rods 504 to rise synchronously, thereby releasing the pressing state on the carrier 2 and the BTB flip elastic pressing module 202. At this time, the carrier 2 and the BTB flip elastic pressing module 202 can return to the initial state to prepare for the next test.

[0155] In summary, through the coordinated work of components such as the bracket 501, the first mounting plate 502, the driving mechanism 503, and the pressing rods 504, the pressing module 5 realizes the precise pressing and stable connection of the carrier 2 and the BTB flip elastic pressing module 202.

[0156] Please refer to Figure 10 , in an implementation manner of this embodiment, the rotary pressing test module 6, as a key component in the entire test system, has a delicate structure design and complete functions. It is mainly composed of core components such as a mounting frame 601, a second mounting plate 602, a Z-axis motor screw module 603, a rotary module 604, and a pressing module 605. The following will elaborate in detail and formally on the specific structural features, functional roles, and coordinated working principles of each component.

[0157] The mounting frame 601, as the basic support structure of the rotary pressing test module 6, is firmly mounted on the machine base 1. Its design fully considers the stability and load-bearing capacity of the overall structure. It is made of high-strength and high-rigidity materials and undergoes precise machining and assembly to ensure that it can withstand various forces generated during the operation of the rotary module 604 and the pressing module 605 without deformation or damage. The shape and size of the mounting frame 601 are carefully calculated and optimized, which not only meet the installation requirements of the rotary pressing test module 6 but also provide sufficient space and convenience for the layout and movement of subsequent components.

[0158] The second mounting plate 602, as the main moving component of the rotary pressing test module 6, is arranged on the mounting frame 601 in a liftable manner through the Z-axis motor screw module 603. The material and manufacturing process of the second mounting plate 602 have been strictly screened and optimized to ensure that it has sufficient rigidity and strength to withstand the weight of the rotary module 604 and the pressing module 605 and various stresses generated during the working process. At the same time, the surface of the second mounting plate 602 is precisely machined and processed to ensure that the connection between it and the rotary module 604 and the pressing module 605 is firm and reliable, without loosening or falling off.

[0159] The Z-axis motor lead screw module 603 serves as the vertical motion drive mechanism of the rotary pressing test module 6, responsible for driving the second mounting plate 602 to perform lifting and lowering motions. This module adopts advanced motor drive technology and a precise lead screw transmission system, enabling the second mounting plate 602 to be lifted and lowered smoothly, quickly, and with high precision. The control precision and response speed of the Z-axis motor lead screw module 603 have undergone strict testing and adjustment to ensure that it can meet the high-precision requirements for the positions and speeds of the rotary module 604 and the pressing module 605 during the testing process. In addition, this module also has safety functions such as overload protection and position feedback to ensure that abnormal situations can be detected and handled in a timely manner during the testing process, safeguarding the safety of the testing equipment and personnel.

[0160] The rotary module 604, as one of the core execution components of the rotary pressing test module 6, is precisely set on the second mounting plate 602. Its design fully considers the requirements of the crown rotation test, adopts high-precision rotary drive technology and a stable transmission structure, and can achieve smooth, fast, and precise rotation of the crown. Parameters such as the rotation angle, speed, and torque of the rotary module 604 can be flexibly adjusted according to the actual testing requirements to meet the testing requirements of different models and specifications of crowns.

[0161] The pressing module 605, as another core execution component of the rotary pressing test module 6, is also set on the second mounting plate 602. Its design fully considers the requirements of the crown pressing test, adopts high-precision pressure control technology and a stable pressing structure, and can achieve uniform, stable, and controllable pressing of the crown. Parameters such as the pressing force, pressing speed, and pressing time of the pressing module 605 can be precisely adjusted according to the actual testing requirements to ensure the accuracy and reliability of the test results.

[0162] In practical applications, when the testing process requires rotary and pressing tests on the crown, the Z-axis motor lead screw module 603 is first started and drives the second mounting plate 602 to descend, thereby driving the rotary module 604 and the pressing module 605 to descend synchronously until they come into contact with the crown. Subsequently, the rotary module 604 starts to work and drives the crown to perform a rotation test, while the pressing module 605 also performs a stable pressing operation on the crown. During the rotary and pressing tests, the working parameters of the rotary module 604 and the pressing module 605 are precisely controlled and adjusted according to the actual testing requirements to ensure the accuracy and reliability of the test results.

[0163] When the rotary and pressing tests are completed, the Z-axis motor lead screw module 603 drives the second mounting plate 602 to rise and drives the rotary module 604 and the pressing module 605 to rise synchronously, thereby releasing the rotary and pressing states of the crown. At this time, the crown can return to its initial state, preparing for the next test.

[0164] In summary, the rotary pressing test module 6 realizes the precise rotation and stable pressing test of the crown through the coordinated work of components such as the mounting bracket 601, the second mounting plate 602, the Z-axis motor screw module 603, the rotary module 604, and the pressing module 605.

[0165] Please refer to again Figure 10 , and in combination with the reference Figures 11-13 , in an implementation manner of this embodiment, the rotary module 604 and the pressing module 605, as the core components of the rotary pressing test module 6, are exquisitely designed and fully functional, providing a high-precision and high-stability solution for the rotation and pressing test of the crown. The following will elaborate in detail and formally on the specific structural features, functional roles, and coordinated working principles of the components of the rotary module 604 and the pressing module 605.

[0166] The rotary module 604 is mainly composed of key components such as a rotary motor 6041, a synchronous belt 6042, a torque sensor 6043, a rotary shaft 6044, and a rubber-coated head 6045. These components work together to jointly achieve precise rotation control of the crown.

[0167] The rotary motor 6041, as the power source of the rotary module 604, adopts high-performance motor drive technology and can output stable and strong rotary power, providing a strong guarantee for the work of subsequent components.

[0168] The synchronous belt 6042, as the power transmission bridge between the rotary motor 6041 and the rotary shaft 6044, is made of high-strength and high-precision synchronous belt material, which can ensure that the rotary power output by the rotary motor 6041 is accurately and stably transmitted to the rotary shaft 6044, realizing the smooth rotation of the rotary shaft 6044.

[0169] The torque sensor 6043 is set at the output end of the rotary motor 6041 and adopts high-precision torque measurement technology, which can monitor the torque magnitude generated during the rotation in real time. By analyzing and processing the torque data, it can be judged whether the crown rotates in place, thus realizing precise control of the rotation angle of the crown.

[0170] The rotary shaft 6044, as the main moving component of the rotary module 604, is made of high-strength and high-rigidity materials and can withstand various stresses generated during rotation without deformation or damage. The surface of the rotary shaft 6044 has been precisely machined and processed to ensure the firm and reliable connection between it and the synchronous belt 6042, the torque sensor 6043, and the rubber-coated head 6045.

[0171] The rubber-coated head 6045 is set at the end of the rotating shaft 6044 and is made of a soft and wear-resistant rubber material, which can be tightly sleeved on the crown. During rotation, the rubber-coated head 6045 can drive the crown to rotate smoothly and quickly, while avoiding damage to the crown.

[0172] The pressing module 605 is mainly composed of key components such as an air source 6051, a spring 6052, a micro single-acting cylinder 6053, a pressure sensor 6054, and an air-electric integrated slip ring 6055. These components work together to achieve precise pressing control of the crown.

[0173] As the power source of the pressing module 605, the air source 6051 uses high-pressure and high-stability compressed air as the working medium, providing strong support for the operation of subsequent components.

[0174] As the connection bridge between the air source 6051 and the rotating shaft 6044, the air-electric integrated slip ring 6055 adopts advanced air-electric integrated design technology, which can achieve stable transmission of compressed air and electrical signals, and can prevent the air pipe and wire from being entangled during the rotation test. Through the air-electric integrated slip ring 6055, the air source 6051 can be reliably connected to the rotating shaft 6044, providing compressed air for the subsequent air circuit 6056 and the micro single-acting cylinder 6053.

[0175] The air circuit 6056 is set inside the rotating shaft 6044 and is manufactured by precise processing technology, which can ensure the sealing and stability of compressed air during transmission. One end of the air circuit 6056 is connected to the air source 6051, and the other end is connected to the micro single-acting cylinder 6053, providing compressed air for the micro single-acting cylinder 6053.

[0176] The pressure sensor 6054 is sleeved on the rotating shaft 6044 and adopts high-precision pressure measurement technology, which can real-time monitor the magnitude of the force when pressing the crown. By analyzing and processing the pressure data, it can be judged whether the crown receives sufficient pressing force, so as to achieve precise control of the pressing force of the crown.

[0177] The spring 6052 is sleeved on the rotating shaft 6044, and one end of it abuts against the end of the rotating shaft 6044, and the other end abuts against the pressure sensor 6054. The spring 6052 is made of a material with high elasticity and high stability, which can provide a stable supporting force for the pressure sensor 6054 and ensure the stable and reliable contact between the pressure sensor 6054 and the crown during pressing.

[0178] The micro single-acting cylinder 6053 is arranged inside the rubber-coated head 6045 and is set at the end corresponding to the air passage 6056. It is used to first extend and contact the crown when the crown needs to be pressed, and then perform the pressing operation on the crown under the drive of compressed air;

[0179] In practical applications, when the rotation and pressing tests of the crown are required during the test process, the rotation module 604 and the pressing module 605 will work together to jointly achieve precise control of the crown.

[0180] First, the rotation motor 6041 starts and outputs rotational power, and the rotational power is transmitted to the rotating shaft 6044 through the synchronous belt 6042. The rotating shaft 6044 drives the rubber-coated head 6045 to rotate, thereby driving the crown to perform a rotation test. During the rotation process, the torque sensor 6043 monitors the magnitude of the torque generated during the rotation in real time and determines whether the crown rotates in place.

[0181] At the same time, when the crown needs to be pressed, the micro single-acting cylinder 6053 extends and contacts the crown. The air source 6051 provides compressed air to the air passage 6056 inside the rotating shaft 6044 through the air-electricity integrated slip ring 6055, and the compressed air drives the micro single-acting cylinder 6053 to perform the pressing operation on the crown. During the pressing process, the pressure sensor 6054 monitors the magnitude of the force when pressing the crown in real time and determines whether the crown receives sufficient pressing force.

[0182] When the rotation and pressing tests are completed, the rotation motor 6041 stops working and drives the rubber-coated head 6045 to stop rotating; at the same time, the micro single-acting cylinder 6053 resets under the action of the spring 6052 and releases the pressing state of the crown. At this time, the crown can return to the initial state to prepare for the next test.

[0183] In summary, the rotation module 604 and the pressing module 605 jointly achieve precise rotation and stable pressing tests of the crown through the coordinated work of each component.

[0184] An automatic crown tester provided by an embodiment of the present invention realizes efficient and accurate testing of the crown through an integrated automated design. The tester utilizes the sliding function of the drawer-type support module to facilitate the rapid loading and unloading of the carrier, significantly improving the efficiency of the testing process. At the same time, the combined use of the probe module and the pressing module ensures a stable electrical connection between the crown and the probe, enhancing the consistency and reliability of the test results. In addition, the application of the rotary pressing test module enables the automatic completion of the rotation and pressing tests of the crown, not only reducing the burden of manual operation but also avoiding test errors caused by human factors. In summary, the automatic crown tester of the present invention can effectively improve the testing efficiency, ensure the testing quality, reduce the labor cost, and increase the overall automation level of the production line, which has important practical value and promotion prospects for the watch manufacturing industry and the field of precision instrument testing.
