[0002] Air tightness testing is frequently encountered in production and daily life. It typically involves sealing the air outlet, injecting high-pressure gas into the product under test through the air inlet, and then applying soapy water to areas prone to leakage. If bubbles form in the soapy water, the product's air tightness is considered unsatisfactory; otherwise, it is considered satisfactory. When a large number of products require air tightness testing, the workload and labor intensity are significant. This is especially true when potential leaks occur on multiple surfaces of the product. Repeated installations to change the product's surface and present it to the testing personnel further increase the workload and difficulty. Therefore, there is an urgent need to solve the technical problem of completing air tightness testing with a single installation to improve the efficiency of air tightness testing.

[0003] To address this, we developed a rotary worktable that can complete the airtightness test of the product in a single installation, resulting in high airtightness testing efficiency. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: the rotary worktable 2 includes a mounting base 21 and a horizontal rotary table 22; a set of vertical supports 24 are symmetrically arranged on the mounting base 21; the horizontal rotary table 22 is rotatably mounted on the vertical supports 24 around a horizontal axis; the horizontal rotary table 22 is driven to rotate around the horizontal axis by a first driving device 23; a vertical rotary table 26 rotatably mounted around a vertical axis is horizontally arranged on the horizontal rotary table 22; a second driving device 25 is arranged on the horizontal rotary table 22; the second driving device 25 can drive the vertical rotary table 26 to rotate around its vertical center line; gears 27 are evenly distributed on the outer circumference of the vertical rotary table 26; a small gear (not shown) is arranged on the second driving device 25; the small gear and gear 27 cooperate to enable the vertical rotary table 26 to rotate around its vertical center line; a clamping device 28 is arranged on the upper surface of the vertical rotary table 26; the clamping device 28 is used to quickly clamp the product under test (not shown).

[0018] The rotary table 2 is used in a sealing test device, which includes a main support 1; the rotary table 2 is horizontally arranged inside the main support 1; a camera 3 is arranged inside the top of the main support 1; a display 4 is arranged outside the main support 1; the top of the main support 1 is provided with mutually perpendicular front-to-back horizontal guide rails 31 and left-to-right horizontal guide rails 32; the left-to-right horizontal guide rails 32 are arranged on the front-to-back horizontal guide rails 31 and can move horizontally along them; the camera 3 is arranged on the left-to-right horizontal guide rails 32 and can move horizontally left-to-right; the camera 3 is connected to the display 4 so that the images captured by the camera 3 can be displayed on the display 4.

[0019] In this embodiment, the vertical rotating stage 26 is also provided with at least one high-pressure gas connector (not shown); one end of each high-pressure gas connector is provided corresponding to the air inlet of the product under test for docking; the other end of each high-pressure gas connector is connected to a high-pressure gas source (not shown), and high-pressure gas can be input to the product under test (not shown) by turning on the high-pressure gas source.

[0020] During operation, the product under test is first placed in a preset position on the vertical rotating stage 26, and the air inlet of the product under test is connected to the corresponding high-pressure gas connector. Then, the product under test is clamped from the top using the clamping device 28. Next, soapy water is applied to areas where leakage may occur, and then the high-pressure gas source is turned on to input high-pressure gas into the product under test. Then, the camera 3 is controlled to move along the front and rear horizontal guide rails 31 and the left and right horizontal guide rails 32 and take pictures. At the same time, the display 4 shows the pictures taken by the camera 3 so that the operator can check whether bubbles are generated in the soapy water. If bubbles are generated in the soapy water, it means that the air tightness of the product under test does not meet the requirements; otherwise, it means that the air tightness of the product under test meets the requirements. If the relative position of the product under test and the camera 3 needs to be changed, the first driving device 23 can be controlled to drive the horizontal rotating stage 22 to rotate around the horizontal axis; the second driving device 25 drives the vertical rotating stage 26 to rotate around its vertical center line. In this way, the air tightness test of the product under test can be completed in one installation.

At this time, the product that has completed the air tightness test can be taken out, and then a new product can be replaced. Repeating the above steps can achieve continuous and efficient air tightness testing.
