Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of watches, in particular to an air tightness detection device for watches. Background Technique

[0002] At present, there are many varieties of smart watches produced on the market. Before the watches leave the factory, it is necessary to conduct airtightness tests on the call ports, microphones, backplane control modules, reset keys, volume keys, press adjustment keys, rotation adjustment keys, etc. on the watches, collect and judge the seals of the watch products, and prevent defective products from flowing out.

[0003] When detecting the air tightness of watches, most of the detection methods are to introduce a certain pressure and a certain volume of gas into a closed workpiece cavity, then disconnect the compressed air supply of the component, let it stand for a period of time to make its pressure stable, and measure the pressure change after a predetermined measurement time. If there is leakage, the pressure will drop, and the air tightness of the watch is judged according to the pressure change.

[0004] However, when detecting, generally the watch needs to be placed inside the detection box first. After the detection is completed, the watch is taken out and a new watch is put in for detection. During the process of taking and placing the watch back and forth, it takes a certain amount of time, and the detection device is in a standby state, and the utilization rate of the detection device is not high, which affects the detection efficiency of the air tightness of the watch. For this reason, we propose an air tightness detection device for watches. Content of the Utility Model

The outer surface of the limiting rod is sleeved with a limiting ring. The limiting ring is fixedly connected to the front surface of a baffle. The back surface of the baffle is fixedly connected with a threaded pipe. The inside of the threaded pipe is threadedly connected with a threaded rod. One end of the threaded rod is fixedly connected to the output end of a servo motor;

[0008] One side of the baffle is fixedly connected with a first sealing ring. The first sealing ring is fixedly connected to one side of a detection placement box. The other side of the detection placement box is fixedly connected with a second sealing ring.

[0009] In order to make the installation of the first mounting seat more stable, as a watch airtightness detection device of the present utility model, the other end of the limiting rod is fixedly connected to the upper surface of the fixed frame, the inner wall of the fixed frame is fixedly connected with a first mounting seat, and a threaded rod is installed inside the first mounting seat through a bearing.

[0010] In order to make the rotation of the threaded rod more stable, as a watch airtightness detection device of the present utility model, one side of the detection box is fixedly connected with a mounting support plate, the front surface of the mounting support plate is fixedly connected with a second mounting seat, and a threaded rod is installed inside the second mounting seat through a bearing.

[0011] In order to facilitate the start and stop of the servo motor, as a watch airtightness detection device of the present utility model, a control switch is fixedly installed on the upper surface of the fixed frame, and the control switch is electrically connected to the servo motor through a wire.

[0012] In order to facilitate the supply of air into the detection box, as a watch airtightness detection device of the present utility model, an airtight detector is fixedly installed on the back surface of the detection box, and the airtight detector is connected to the detection box through an air pipe.

The outer surface of the limiting rod 2 is sleeved with a limiting ring 3. The limiting ring 3 is fixedly connected to the front surface of a baffle 4. The back surface of the baffle 4 is fixedly connected with a threaded pipe 5. The threaded pipe 5 is internally threaded with a threaded rod 6. One end of the threaded rod 6 is fixedly connected to the output end of a servo motor 7;

[0025] One side of the baffle 4 is fixedly connected with a first sealing ring 8. The first sealing ring 8 is fixedly connected to one side of a detection placement box 9. The other side of the detection placement box 9 is fixedly connected with a second sealing ring 10.

[0026] During specific use, through the cooperative setting among the detection box 1, the limit rod 2, the limit ring 3, the baffle 4, the threaded pipe 5, the threaded rod 6, the servo motor 7, the first sealing ring 8, the detection placement box 9 and the second sealing ring 10, when the staff is detecting the watches, multiple watches can be sequentially placed inside the detection placement boxes 9 at different positions. After the watches in the previous detection placement box 9 are detected, the staff only needs to start the servo motor 7. The servo motor 7 drives the threaded rod 6 to rotate, so that the previous detection placement box 9 can be moved out of the detection box 1, and the next detection placement box 9 enters the detection box 1. When the watches in the next detection placement box 9 start to be detected, the staff then takes out the previously detected watches from the detection placement box 9, which makes the utilization rate of the detection box 1 higher and the downtime shorter, greatly improving the detection efficiency.

[0027] In this embodiment, the other end of the limit rod 2 is fixedly connected to the upper surface of the fixed frame 11, and a first mounting seat 12 is fixedly connected to the inner wall of the fixed frame 11. The threaded rod 6 is installed inside the first mounting seat 12 through a bearing.

[0028] During specific use, through the setting of the fixed frame 11, the first mounting seat 12 can be installed more firmly.

[0029] In this embodiment, a mounting support plate 13 is fixedly connected to one side of the detection box 1, and a second mounting seat 14 is fixedly connected to the front surface of the mounting support plate 13. The threaded rod 6 is installed inside the second mounting seat 14 through a bearing.

[0030] During specific use, through the settings of the first mounting seat 12 and the second mounting seat 14, the threaded rod 6 can rotate more smoothly.

[0031] In this embodiment, a control switch 15 is fixedly installed on the upper surface of the fixed frame 11, and the control switch 15 is electrically connected to the servo motor 7 through a wire.

[0032] During specific use, through the setting of the control switch 15, it is convenient to control the start and stop of the servo motor 7.

[0033] In this embodiment, an airtight detector 16 is fixedly installed on the back surface of the detection box 1, and the airtight detector 16 is connected to the detection box 1 through an air pipe 17.

[0034] During specific use, through the settings of the air pipe 17 and the airtight detector 16, it is convenient to inflate the detection box 1.

[0035] In this embodiment, fixing pieces 18 are fixedly connected to both sides of the detection box 1, a support chassis 19 is fixedly connected to the lower surface of the fixed frame 11, and both the fixing pieces 18 and the support chassis 19 are fixedly connected to the detection table through bolts.

[0036] During specific use, the stability of the device can be better through the settings of the fixing piece 18 and the supporting base frame 19.

[0037] Working principle: When the staff is detecting the watches, multiple watches can be successively placed inside the detection placement boxes 9 at different positions. Then, the staff starts the airtight detector 16, and the airtight detector 16 supplies air into the detection box 1 through the air pipe 17, so as to detect the watches entering the inside of the detection placement boxes 9. Due to the settings of the first sealing ring 8 and the second sealing ring 10, the sealing effect can be better after the detection placement boxes 9 enter the inside of the detection box 1. After the watches inside the previous detection placement box 9 are detected, the staff only needs to start the servo motor 7. The servo motor 7 drives the threaded rod 6 to rotate, so that the previous detection placement box 9 can be moved out of the detection box 1, and the next detection placement box 9 enters the detection box 1. When the watches inside the next detection placement box 9 start to be detected, the staff takes out the previously detected watches from the inside of the detection placement box 9. By continuously repeating the above operations, other watches can be detected.
