Abstract
Description
Technical Field
[0001] This invention relates to the field of watches, and more particularly to a fully automatic testing machine and method for comprehensive parameters of watches. Background Technology
[0002] A wristwatch, also known as a wristwatch, is a portable timepiece worn on the wrist. The main types include mechanical watches and quartz watches. Mechanical watches, as the name suggests, use a mechanical movement, relying primarily on a mainspring mechanism to drive a series of mechanical gears and other mechanisms to achieve high-precision timekeeping. Due to the high precision requirements of mechanical watches, their timekeeping parameters, including daily rate, polarization, and amplitude, are often tested after assembly.
[0003] Traditional testing methods mostly employ static testing, which involves testing the watch in four fixed positions: face up, face side pointing towards 6 o'clock, face down, and face side pointing towards 9 o'clock. In these four fixed positions, an audio sensor transmits the movement's timekeeping signal. After processing, data such as daily rate, polarization, and amplitude are obtained. The tested data are then compared with standard values to determine the accuracy of the timekeeping.
[0004] This simple, singular testing method only examines a limited number of fixed positions during testing. However, in actual use, watches encompass all angles and various dynamic and static scenarios. The fixed testing method cannot cover all positions encountered in real-world use, leading to significant discrepancies between test data and actual usage data. Furthermore, its static testing conditions cannot simulate continuous movement such as walking, resulting in a severe disconnect between the testing scenario and real-world conditions. Therefore, current conventional static watch testing results are often unrepresentative, and even watches that pass the test may still exhibit inaccurate timekeeping in real-world use. In addition, the low level of automation in existing testing equipment also limits its efficiency and reliability. Summary of the Invention

[0028] Steps 2-3: Static comparison test. Place the watch under test on the clamping and positioning measuring mechanism, start the fully automatic watch comprehensive parameter testing machine, and the equipment will automatically test the watch under test again according to the set static parameters to obtain the actual data set of daily rate, polarization and oscillation amplitude of the watch under test.
[0029] Step 2-4: Static analysis and judgment. Compare the actual data set of daily rate, polarization, and amplitude of the watch under test obtained in Step 2-3 with the standard data set of daily rate, polarization, and amplitude of the qualified watch obtained in Step 2-2 to determine the qualification of the watch under test.

[0043] like Figures 1 to 10 As shown, this invention provides a fully automatic watch comprehensive parameter testing machine 100, which includes a testing platform 10, a swing mechanism 20, a wrist rotation mechanism 30, a position rotation mechanism 40, a clamping and positioning measurement mechanism 50, and a robotic arm mechanism 60.

[0044] A frame 11 is erected on the test bench 10. The swing mechanism 20 includes a rear arm swing mechanism 21 mounted on the frame 11 and a forearm swing mechanism 22 mounted at the lower end of the rear arm swing mechanism 21. The wrist rotation mechanism 30 is mounted on the forearm swing mechanism 22. The orientation rotation mechanism 40 is mounted on the wrist rotation mechanism 30. The clamping positioning and measuring mechanism 50 is mounted on the orientation rotation mechanism 40. The robotic arm mechanism 60 is mounted on the test bench 10 and located on the front side of the frame 11.
[0045] During operation, the fully automatic watch parameter testing machine 100 can selectively perform dynamic simulated wearing tests or static orientation tests. The dynamic simulated wearing test is further divided into standard dynamic simulated wearing tests and random dynamic simulated wearing tests.
[0046] In the standard dynamic simulation wearing test, the watch comprehensive parameter fully automatic testing machine 100 sets the standard dynamic simulation test parameters and controls the rear arm swing mechanism 21, the forearm swing mechanism 22, the wrist rotation mechanism 30 and the orientation rotation mechanism 40 to simulate the dynamic movements of the arm and wrist in the human body running and walking, respectively, and performs a standard dynamic simulation wearing test on the watch on the clamping positioning measurement mechanism 50.
[0047] In the random dynamic simulation wearing test, the watch comprehensive parameter fully automatic testing machine 100 sets random dynamic simulation test parameters and controls the rear arm swing mechanism 21, the forearm swing mechanism 22, the wrist rotation mechanism 30 and the orientation rotation mechanism 40 to simulate the dynamic movements of the arm and wrist in other random states of the human body, and performs random dynamic simulation wearing test on the watch on the clamping positioning measurement mechanism 50.
[0048] In the static orientation test, the fully automatic watch comprehensive parameter testing machine 100 sets the static orientation test parameters, controls the wrist rotation mechanism 30 and the orientation rotation mechanism 40 to rotate the orientation angle, and performs a static orientation test on the watch on the clamping positioning measuring mechanism 50.
[0049] The rear arm swing mechanism 21 includes a first positioning sleeve 211, a first rotating shaft 212, a first drive bracket 213, a rear arm swing drive device 214, a first coupling 215, and a rear swing arm 216. The upper end of the frame 11 has a first through-hole (not shown). The first positioning sleeve 211 is installed in the first through-hole, and the first rotating shaft 212 is installed in the first positioning sleeve 211 with its two ends extending to the front and rear sides of the frame 11, respectively. The first drive bracket 213 is installed on the frame 11 and located behind the first through-hole. The rear arm swing drive device 214 is installed on the first drive bracket 213 and horizontally aligned with the rear end of the first rotating shaft 212. The first coupling 215 connects the first rotating shaft 212 and the rear arm swing drive device 214. The rear swing arm 216 is installed at the front end of the first rotating shaft 212.
[0050] The forearm swing mechanism 22 includes a second positioning sleeve 221, a second rotating shaft 222, a second drive bracket 223, a forearm swing drive device 224, a second coupling 225, and a front swing arm 226. The lower end of the rear swing arm 216 has a second through-hole (not shown). The second positioning sleeve 221 is installed in the second through-hole. The second rotating shaft 222 is installed in the second positioning sleeve 221, with its two ends extending to the front and rear sides of the rear swing arm 216, respectively. The second drive bracket 223 is installed on the rear swing arm 216 and located behind the second through-hole. The forearm swing drive device 224 is installed on the second drive bracket 223 and horizontally aligned with the rear end of the second rotating shaft 222. The second coupling 225 connects the second rotating shaft 222 and the forearm swing drive device 224. The front swing arm 226 is installed at the front end of the second rotating shaft 222.
[0051] The rear swing arm 216 in the rear arm swing mechanism 21, driven by the rear arm swing drive device 214, can simulate the swing of the human upper arm; while the front swing arm 226 in the forearm swing mechanism 22, driven by the forearm swing drive device 224, can simulate the swing of the human forearm. Together, they can completely simulate any movement or static posture of the human arm, providing a fully simulated testing environment and conditions for watch testing. Specifically, in this embodiment, both the rear arm swing drive device 214 and the forearm swing drive device 224 are cylinders. The cylinder drive device can provide a strong driving force, thereby ensuring that the swinging movements of the rear arm and forearm are accurate and powerful during the test.
[0052] The wrist rotation mechanism 30 includes a third positioning sleeve 31, a third rotating shaft 32, a third drive bracket 33, a wrist rotation drive device 34, a third coupling 35, and a transition bracket 36. The lower end of the front swing arm 226 is provided with a first mounting plate (not shown) integrally connected to it and extending forward. The first mounting plate has a third mounting through hole (not shown) extending through the left and right sides. The third positioning sleeve 31 is installed in the third mounting through hole. The third rotating shaft 32 is installed in the third positioning sleeve 31, with both ends extending to the left and right sides of the third mounting through hole. The third drive bracket 33 is installed on the front swing arm 226 and located on the right side of the third mounting through hole. The wrist rotation drive device 34 is installed on the third drive bracket 33 and horizontally aligned with the right end of the third rotating shaft 32. The third coupling 35 connects the third rotating shaft 32 and the wrist rotation drive device 34. The transition bracket 36 is installed at the left end of the third rotating shaft 32.
[0053] When the wrist rotation mechanism 30 is activated, the wrist rotation drive device 34 drives the third rotating shaft 32 and the transition bracket 36 mounted at the end of the third rotating shaft 32 to rotate synchronously, thereby simulating the rotational movement of the human wrist. The operation of the wrist rotation mechanism 30 can completely simulate different rotation angles of the human wrist, thus making the watch's detection more comprehensive. Specifically, in this embodiment, the wrist rotation drive device 34 is a drive motor, and the drive control precision of the motor drive device is very high, which can ensure the accuracy of simulating the rotation angle of the human wrist.
[0054] The orientation rotation mechanism 40 includes a fourth positioning sleeve 41, a fourth rotating shaft 42, a fourth drive bracket 43, an orientation rotation drive device 44, and a fourth coupling 45. The transition bracket 36 has a fourth through-hole (not shown) extending from front to back. The fourth positioning sleeve 41 is installed within the fourth through-hole. The fourth rotating shaft 42 is installed within the fourth positioning sleeve 41, with both ends extending to the front and rear sides of the fourth through-hole. The fourth drive bracket 43 is installed on the transition bracket 36 and located behind the fourth through-hole. The orientation rotation drive device 44 is installed on the fourth drive bracket 43 and horizontally aligned with the rear end of the fourth rotating shaft 42. The fourth coupling 45 connects the fourth rotating shaft 42 and the orientation rotation drive device 44.
[0055] When the orientation rotation mechanism 40 is activated, the orientation rotation drive device 44 drives the fourth rotating shaft 42 and the clamping and positioning measuring mechanism 50 to rotate synchronously, thereby automatically and flexibly adjusting the orientation of the watch face on the clamping and positioning measuring mechanism 50. Specifically, in this embodiment, the orientation rotation drive device 44 is a drive motor, and the drive control precision of the motor drive device is very high, which can ensure the accuracy of the orientation adjustment of the watch face.
[0056] The clamping, positioning, and measuring mechanism 50 includes a front panel 51, a rear panel 52, several positioning panels 53, several clamping mechanisms 54, and several measuring mechanisms 55. The front panel 51 and rear panel 52 are both mounted on a fourth rotating shaft 42 and are spaced apart. The two ends of the several positioning panels 53 are respectively connected to and mounted on the front panel 51 and rear panel 52, and the several positioning panels 53 are arranged around the fourth rotating shaft 42. The several clamping mechanisms 54 are respectively mounted on the outer surfaces of the several positioning panels 53, and the several measuring mechanisms 55 are respectively mounted on the outer surfaces of the several positioning panels 53 and are arranged in a one-to-one correspondence with the several clamping mechanisms 54.
[0057] The clamping, positioning, and measuring mechanism 50 features multiple positioning panels 53, clamping mechanisms 54, and measuring mechanisms 55, enabling it to hold and fix multiple watches under test at once and perform simultaneous testing on them. This significantly improves the testing efficiency of the machine.
[0058] The clamping mechanism 54 includes a watch positioning block 541, a fixed clamping block 542, a guide sleeve 543, a lead screw motor 544, and a movable clamping block 545. The watch positioning block 541, the fixed clamping block 542, the guide sleeve 543, and the lead screw motor 544 are all mounted on the positioning panel 53. The fixed clamping block 542 and the guide sleeve 543 are respectively located on both sides of the watch positioning block 541. The lead screw motor 544 is located on the outside of the guide sleeve 543, and its lead screw passes through the guide sleeve 543. The movable clamping block 545 is slidably mounted on the guide sleeve 543 and is abutted against the free end of the lead screw motor 544.
[0059] When the watch needs to be clamped, simply place it on the watch positioning block 541. Then, the lead screw motor 544 will drive the movable clamping block 545 to move, cooperating with the fixed clamping block 542 to clamp and fix the watch. The lead screw motor 544 is powered and controlled by the first electric slip ring 37 and the second electric slip ring 46. The lead screw drive allows for extremely precise control of the clamping force, ensuring that the watch is firmly fixed without over-clamping and damaging it. Specifically, in this embodiment, both the fixed clamping block 542 and the movable clamping block 545 are designed in a V-shape. The V-shaped clamping block structure can clamp the watch more stably.
[0060] The measuring mechanism 55 includes a measuring pin positioning sleeve 551, a measuring pin 552, a fixing screw 553, a spring 554, and a measuring sensor 555. The measuring pin positioning sleeve 551 is mounted on the positioning panel 53 and located outside the fixing block 542. The measuring pin 552 is mounted inside the measuring pin positioning sleeve 551, with one end extending outside the measuring pin positioning sleeve 551. The fixing screw 553 is mounted on the measuring pin positioning sleeve 551 and is correspondingly arranged with the measuring pin 552. The spring 554 is located inside the measuring pin positioning sleeve 551, with both ends abutting against the measuring pin 552 and the fixing screw 553, respectively. The measuring sensor 555 is mounted on the outer end of the measuring pin 552 and extends inside the fixing block 542.
[0061] Specifically, in this embodiment, the measuring sensor 555 is an audio signal pickup. When the testing machine starts to test the watch, the measuring sensor 555, which is mounted on the measuring pin 552 and extends to one side of the fixing block 542, can press against the watch to clearly, accurately, and timely monitor the watch movement's timekeeping information, thereby obtaining data curves such as daily rate, polarization, and amplitude.
[0062] Specifically, in this embodiment, the wrist rotation mechanism 30 further includes a first electric slip ring 37, which is sleeved on the left side of the third rotating shaft 32 and one end of which is connected to the third positioning sleeve 31; the orientation rotation mechanism 40 further includes a second electric slip ring 46, which is sleeved on the front side of the fourth rotating shaft 42 and one end of which is connected to the fourth positioning sleeve 41. The first electric slip ring 37 and the second electric slip ring 46 function as brushes, providing power and transmitting signals to the motors and measuring sensors 555 on the testing machine.
[0063] The robotic arm mechanism 60 includes a robotic arm 61, a vacuum suction cup 62, a robotic arm connecting frame 63, a camera 64, and an aperture 65. The robotic arm 61 is mounted on the test platform 10 and located on the front side of the frame 11. The vacuum suction cup 62 is mounted on the upper end of the robotic arm 61. The robotic arm connecting frame 63 is mounted on the robotic arm 61 and located on one side of the vacuum suction cup 62. The camera 64 and the aperture 65 are both mounted on the robotic arm connecting frame 63, and the aperture 65 is located in front of the lens of the camera 64.
[0064] Specifically, in this embodiment, the robotic arm 61 is a multi-axis, multi-joint structure. During the operation of the testing machine, the robotic arm 61, with the assistance of machine vision from the camera 64, can accurately and firmly grasp the watches using the vacuum suction cup 62, thereby realizing automated loading, inspection, screening, and unloading processes. The automated loading and unloading of the robotic arm 61 is not only highly efficient and reliable, but also significantly reduces labor costs.
[0065] The fully automatic watch comprehensive parameter testing machine 100 also includes several watch carrier frames 70, which are placed on the testing platform 10 and located on the left and right sides of the robotic arm mechanism 60, respectively. Specifically, in this embodiment, the several watch carrier frames 70 include frames to be inspected, qualified frames, and unqualified frames. During the testing process, the robotic arm mechanism 60 can automatically remove the watches to be inspected from the frames to be inspected and place them on the clamping and positioning measuring mechanism 50 for testing; while the watches that have completed the testing can be removed by the robotic arm mechanism 60 and placed into the qualified frames and unqualified frames respectively according to their pass / fail status.
[0066] Understandably, in other embodiments, the fully automatic watch comprehensive parameter testing machine 100 may further include a simulation control system (not shown). The simulation control system includes a dynamic simulated wearing test module (not shown) and a static simulated wearing test module (not shown). The dynamic test control module controls the rear arm swing mechanism 21, the forearm swing mechanism 22, the wrist rotation mechanism 30, and the orientation rotation mechanism 40 to perform a dynamic simulated wearing test. The static test control module controls the wrist rotation mechanism 30 and the orientation rotation mechanism 40 to perform a static orientation test. The dynamic simulated wearing test module includes a standard dynamic simulated wearing test module (not shown) and a random dynamic simulated wearing test module (not shown).
[0067] More specifically, the simulation control system is a computer-processing control device. Its specific spatial installation location is not limited; it only requires signal connections between the system and various mechanisms to achieve information acquisition and motion control of each mechanism. Through the automated and intelligent control of the dynamic simulation wearing test module, the swing mechanism 20, wrist rotation mechanism 30, and orientation rotation mechanism 40 can move automatically, accurately simulating the dynamic posture changes of the human arm and wrist in different scenarios. This achieves a highly realistic dynamic wearing test of the watch, making the watch's test results more comprehensive and representative. The static simulation wearing module can independently control the wrist rotation mechanism 30 and the orientation rotation mechanism 40. These two mechanisms work together to perform routine static tests on the watch, further supplementing the watch's test data and providing a more robust basis for judging the watch's qualification.
[0068] Furthermore, this invention also provides a method for testing the comprehensive parameters of a watch, which uses the aforementioned fully automatic watch comprehensive parameter testing machine 100 to test the comprehensive parameters of the watch. The method includes dynamic simulation testing, which comprises the following steps:
[0069] Step 1-1: Simulation parameter setting. On the fully automatic watch comprehensive parameter testing machine 100, set the automated test parameters, including the swing frequency and swing amplitude parameters of the rear arm swing mechanism 21, the forearm swing mechanism 22, and the wrist rotation mechanism 30, the rotation period and rotation angle parameters of the orientation rotation mechanism 40, and the automated test duration parameters; specifically, in this embodiment, the simulation parameters include running simulation configuration, walking simulation configuration, and random simulation configuration, wherein:
[0070] The specific parameters of the running simulation configuration are as follows: the swing frequency of the rear arm swing cylinder is 100 times / minute, and the swing angle is 40°; the swing frequency of the forearm swing cylinder is 100 times / minute, and the swing angle is 30°; the swing frequency of the wrist rotation drive device 34 is 100 times / minute, and the swing angle is 60°; the azimuth rotation drive device 44 rotates 90° every 15 seconds; and the running time test is 1 minute.
[0071] The specific parameters of the walking simulation configuration are as follows: the swing frequency of the rear arm swing cylinder is 50 times / minute, and the swing angle is 60°; the swing frequency of the forearm swing cylinder is 50 times / minute, and the swing angle is 30°; the swing frequency of the wrist rotation drive device 34 is 50 times / minute, and the swing angle is 60°; the orientation rotation drive device 44 rotates 90° every 15 seconds; the walking time test is 2 minutes.
[0072] The specific parameters of the random simulation configuration are randomly generated by the control system of the test machine within a reasonable parameter range, and then tested.
[0073] Step 1-2: Simulation reference test. Place the qualified watch on the clamping and positioning measuring mechanism 50, start the fully automatic watch comprehensive parameter testing machine 100. The equipment performs automatic testing on the qualified watch according to the set simulation parameters and measures the daily rate, polarization, and standard curve of the qualified watch.
[0074] Steps 1-3: Simulation comparison test. Place the watch under test on the clamping and positioning measuring mechanism 50, start the fully automatic watch comprehensive parameter testing machine 100, and the equipment will automatically test the watch under test again according to the set simulation parameters to obtain the actual curves of daily rate, polarization and oscillation of the watch under test.
[0075] Steps 1-4: Simulation analysis and judgment. Compare the actual curves of daily rate, polarization, and amplitude of the watch under test obtained in Step 1-3 with the standard curves of daily rate, polarization, and amplitude of the qualified watch obtained in Step 1-2 to determine the qualification of the watch under test.
[0076] The comprehensive parameter testing method for watches also includes static testing, which includes the following steps:
[0077] Step 2-1: Static parameter setting. On the fully automatic watch comprehensive parameter testing machine 100, set the automated test parameters, including the rotation cycle and rotation angle parameters of the wrist rotation mechanism 30 and the orientation rotation mechanism 40, and the automated test count parameter; specifically, in this embodiment, the static test is set such that the rear arm swing cylinder and the forearm swing cylinder do not operate, and:
[0078] With the orientation rotation drive 44 stationary, the wrist rotation drive 34 rotates to bring the watch face to an upward horizontal position, pauses for 15 seconds, and measures the first data. With the orientation rotation drive 44 stationary, the wrist rotation drive 34 rotates to bring the watch face to a vertical position, pauses for 15 seconds, and measures the second data. With the wrist rotation drive 34 stationary, the orientation rotation drive 44 rotates to bring the watch face to a downward horizontal position, pauses for 15 seconds, and measures the third data. With the wrist rotation drive 34 stationary, the orientation rotation drive 44 rotates to bring the watch face to a vertical position, pauses for 15 seconds, and measures the fourth data.
[0079] Step 2-2: Static reference test. Place the qualified watch on the clamping and positioning measuring mechanism 50, start the fully automatic watch comprehensive parameter testing machine 100, and the equipment will automatically test the qualified watch according to the set static parameters to obtain the daily rate, polarization and oscillation standard data set of the qualified watch.
[0080] Steps 2-3: Static comparison test. Place the watch under test on the clamping and positioning measuring mechanism 50, start the fully automatic watch comprehensive parameter testing machine 100, and the equipment will automatically test the watch under test again according to the set static parameters to obtain the actual data set of daily rate, polarization and oscillation amplitude of the watch under test.
[0081] Step 2-4: Static analysis and judgment. Compare the actual data set of daily rate, polarization, and amplitude of the watch under test obtained in Step 2-3 with the standard data set of daily rate, polarization, and amplitude of the qualified watch obtained in Step 2-2 to determine the qualification of the watch under test.
[0082] The beneficial effects of this invention, a fully automatic watch comprehensive parameter testing machine 100 and testing method, are as follows: By designing a dynamic simulation structure and separately designing dynamic simulation wearing tests and static orientation tests, it can completely simulate various scenarios in which a person wears and uses a watch, allowing the watch to undergo more comprehensive and representative testing, greatly improving the accuracy of the watch testing results; moreover, during the dynamic simulation testing process, it can obtain extremely detailed dynamic curves of parameters such as daily rate, polarization, and amplitude under various conditions, which can analyze the main factors affecting product quality and provide guidance for improving product quality; the testing machine is designed for fully automated operation, which can greatly improve testing efficiency while saving labor costs; this invention is highly practical and has strong promotional significance.
[0083] The embodiments described above illustrate only one implementation of the invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the invention. Therefore, the scope of protection of the invention patent should be determined by the appended claims.
