Technical Field

[0001] The present invention relates to the technical field of smart watch detection, and particularly to a waterproof detection device and method for smart watches. Background Art

[0002] When smart watches are initially designed, a batch is first produced for testing to find design defects. One of the test items is waterproof detection, and the waterproof performance of the watch is detected by the immersion method or the air pressure method. However, the existing water detection equipment using the clear water method cannot intuitively obtain the water leakage points.

[0003] Chinese Patent with the authorization announcement number CN216284689U discloses a waterproof and pressure-resistant test device for smart watches. By setting a pressure sensor on the pressing device, the pressure-resistant performance of the smart watch can be accurately tested. Through the profiling groove provided on the fixing seat and adapted to the smart watch, it is beneficial for the smart watch to be quickly and accurately positioned, improving the test efficiency. This utility model combines the waterproof and pressure-resistant detections of the smart watch on the same test device.

[0004] However, this device still has deficiencies: this device needs to set a profiling groove adapted to the smart watch, with a large limitation and cannot be applied to watches of different specifications. And this device cannot accurately judge the water seepage points. At the same time, this device needs to manually load and unload one by one, with a long intermittent time, affecting the efficiency of batch detection. Summary of the Invention

[0006] The technical solution of the present invention: On the one hand, the present invention proposes a waterproof detection device for smart watches, including a frame, a sealing cover is arranged on the frame, a circular groove is arranged inside the sealing cover, and a placing and taking port A, a through hole A and a through hole B communicating with the circular groove are arranged on the sealing cover.

[0007] A disc, the disc is arranged in the circular groove and rotates coaxially therewith. A number of circular holes adapted to the through hole B are arranged in an annular array around its axis on the disc. A limiting ring is arranged inside the lower end opening of the circular hole. A number of limiting rods slidably connected thereto are arranged on the limiting ring. The top of the limiting rod is connected to a permanent magnet ring. A suspension rod is arranged at the bottom of the permanent magnet ring. A porous support plate with an outer diameter not greater than the inner diameter of the limiting ring is arranged at the bottom of the suspension rod. And a spring is sleeved on the limiting rod, and the two ends of the spring respectively abut against the limiting ring and the permanent magnet ring.

[0008] A rotation driving component, the rotation driving component is arranged on the sealing cover and drives the disc to rotate.

[0009] A water storage bucket is arranged on the frame. The upper opening of the water storage bucket is wrapped outside the through hole B. A camera A with its lens facing upward is arranged inside the water storage bucket, and several cameras B with their lenses horizontally facing the central axis of the water storage bucket are arranged on the inner wall of the water storage bucket. A pressure detection component is arranged inside the water storage bucket.

[0010] A piston is movably arranged on the frame and is coaxial with the through hole A. The piston is adapted to the through hole B, and a camera C with its lens facing downward is arranged at the bottom of the piston.

[0011] And a lifting drive component is arranged on the frame and is drivingly connected to the piston.

[0012] Preferably, the through hole A is located directly above the through hole B, and the inner diameter of the through hole A is larger than the inner diameter of the through hole B.

DETAILED DESCRIPTION OF THE INVENTION

[0032] Embodiment 1

[0033] AsFigures 1-5 As shown in the figure, an intelligent watch waterproof detection device proposed by the present invention includes a frame 1, a disc 3, a rotary drive assembly 4, a water storage bucket 10, a piston 16 and a lifting drive assembly. A sealing cover 2 is arranged on the frame 1. A circular groove 201 is arranged inside the sealing cover 2. An access port A 202, a through hole A 203 and a through hole B 204 communicating with the circular groove 201 are arranged on the sealing cover 2. The through hole A 203 is located directly above the through hole B 204, and the inner diameter of the through hole A 203 is larger than that of the through hole B 204. The disc 3 is arranged in the circular groove 201 and rotates coaxially with it. The bottom surface of the disc 3 fits the bottom surface of the circular groove 201. A number of circular holes 301 adapted to the through hole B 204 are arranged on the disc 3 in an annular array around its axis. A limiting ring 5 is arranged on the inner side of the lower end opening of the circular hole 301. A number of limiting rods 6 slidably connected with it are arranged on the limiting ring 5. The top end of the limiting rod 6 is connected with a permanent magnet ring 7. A suspension rod is arranged at the bottom of the permanent magnet ring 7. The limiting rod 6 includes a guiding rod and a positioning block. The guiding rod penetrates through the limiting ring 5 and is slidably connected with it. The top end of the guiding rod is connected with the permanent magnet ring 7. The positioning block is connected with one end of the guiding rod below the limiting ring 5. A porous support plate 8 with an outer diameter not larger than the inner diameter of the limiting ring 5 is arranged at the bottom of the suspension rod. A spring 9 is sleeved on the guiding rod. The two ends of the spring 9 are respectively abutted against the limiting ring 5 and the permanent magnet ring 7. A number of access ports B 302 are arranged on the side wall of the disc 3 in an annular array around its axis. Each access port B 302 communicates with the corresponding circular hole 301 on its side. The rotary drive assembly 4 includes a motor. A spline shaft rotating coaxially with it is arranged on the sealing cover 2. The disc 3 is coaxially connected with the spline shaft. The body of the motor is connected with the sealing cover 2. The output end of the motor is connected with the spline shaft. The water storage bucket 10 is arranged on the frame 1. The upper opening of the water storage bucket 10 is covered outside the through hole B 204. A camera A 13 with its lens facing upward is arranged inside the water storage bucket 10. A number of cameras B 14 with their lenses horizontally facing the central axis of the water storage bucket 10 are arranged on the inner wall of the water storage bucket 10. A pressure detection assembly is arranged inside the water storage bucket 10. The pressure detection assembly includes a pressure sensor and a controller. The pressure sensor is electrically connected with the controller. At the same time, a drain pipe 11 is arranged at the bottom of the water storage bucket 10. A high-pressure valve 12 for controlling the on-off inside it is arranged in the drain pipe 11. The piston 16 is movably arranged on the frame 1 and is coaxially with the through hole A 203. The piston 16 is adapted to the through hole B 204. An annular groove is arranged on the side wall of the piston 16. A sealing ring 161 is arranged in the annular groove. A camera C 18 with its lens facing downward is arranged at the bottom of the piston 16. The camera C 18 can pass through the inner hole of the limiting ring 5. At the same time, a display connected to each camera is arranged on the frame 1. The lifting drive assembly includes but is not limited to a hydraulic cylinder 17. The body of the hydraulic cylinder 17 is arranged on the frame 1. The output end of the hydraulic cylinder 17 is connected with the piston 16. A carriage 15 slidably connected with it is arranged on the frame 1. The carriage 15 is connected with the piston 16.

[0034] In this embodiment, due to the tension of the spring 9, when the piston 16 is in the high position, the permanent magnet ring 7 remains in the high position. At this time, the upper surface of the porous support plate 8 is not lower than the lower edges of the pick-and-place port A202 and the pick-and-place port B302, which is convenient for the staff to pick and place the smart watch. The piston 16 is adapted to the through hole B204, so that after the piston 16 enters the through hole B204, the air between the piston 16 and the liquid surface starts to be compressed, thereby gradually increasing the peripheral pressure value of the watch. During the waterproof detection at one end, the feeding and discharging at the other end are not delayed, saving the intermediate intermittent time and improving the work efficiency. At the same time, through the multiple cameras provided, the state of the watch in the underwater environment can be detected from different angles, and the bubble points can be detected in time during the process of generating bubbles.

[0035] Embodiment 2

[0036] As Figure 1 、 Figure 3 and Figure 5 shown, for an intelligent watch waterproof detection device proposed by the present invention, compared with Embodiment 1, an electromagnet 19 opposite to the permanent magnet ring 7 is provided at the bottom of the piston 16.

[0037] In this embodiment, when the piston 16 starts to move, the electromagnet 19 is energized so that the polarities of the sides close to the permanent magnet ring 7 are the same. At this time, the permanent magnet ring 7 is first pressed down by the repulsive force between the electromagnet 19 and the permanent magnet ring 7 until it contacts the limit ring 5. Subsequently, when the piston 16 continues to be pressed down, the height value of the porous support plate 8 in the water remains unchanged, avoiding inaccurate measurement of the waterproof pressure resistance of the intelligent watch due to the change in its water entry depth.

[0038] Embodiment 3

[0039] The present invention proposes an intelligent watch waterproof detection method, which uses the intelligent watch waterproof detection device described in Embodiment 1 or Embodiment 2, and specifically includes the following steps:

[0040] S1. Add an appropriate amount of water into the water storage bucket 10 so that the liquid surface submerges the camera A13 and the camera B14.

[0041] S2. The rotation drive assembly 4 drives the disc 3 to intermittently rotate around its axis, so that each circular hole 301 circulates and aligns with the pick-and-place port A202, the through hole A203, and the through hole B204, and the smart watch to be detected is placed on the porous support plate 8 along the pick-and-place port A202.

[0042] S3. When the porous support plate 8 carrying the smart watch rotates above the through hole B204, the lifting drive assembly drives the piston 16 to descend and push the permanent magnet ring 7 downward, so that the porous support plate 8 and the smart watch enter the water storage bucket 10 and are located below the liquid surface.

[0043] S4. Start cameras A13, B14, and C18, and each camera detects from a different angle to determine whether there are bubbles and the positions of the bubbles.

[0044] S5. Continue to push down the piston 16. The piston 16 compresses the through-hole B204 and the air above the liquid level to perform a pressure test on the underwater smartwatch.

[0045] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
