Description

Technical Field

[0001] The utility model relates to the technical field of product air tightness testing, in particular to a double-station air tightness testing structure. Background Art

[0002] Currently, the automatic airtightness testing structure on the market is usually an online test on a turntable. The test results of this type of test are generally in the form of a single-station test, that is, there are multiple production or testing stations on the turntable, and each product will pass through these stations in turn. When the product rotates one circle, the established process can be completed.

[0003] However, we found in actual use that the existing air tightness test steps are generally as follows: rotate the product to be tested for air tightness to the test station; turn on the external inflation device to allow the gas to flow into the product to be tested; use pressure sensors and flow meters to measure gas flow and pressure; record key data during the test, such as pressure changes, gas flow, etc., and judge whether the air tightness performance of the product meets the requirements based on the test results. The whole process generally takes about 10 seconds, but the remaining stations only take 5 or 6 seconds to complete at most. This means that after the remaining stations are completed, it is still necessary to wait for the air tightness test station to be completed, which greatly affects the work efficiency of the remaining stations and, to a certain extent, affects the normal production and testing efficiency of the entire product. For this reason, we propose a double-station air tightness test structure. Utility Model Content

[0036] The shift switching unit 5 includes a shift base 51 arranged on the mounting frame 1, two test cavities 3 are respectively arranged on the shift base 51, plugs 52 are respectively arranged on both sides of the mounting frame 1, and a shift component 6 is arranged on the mounting frame 1, which is used to drive any shift base 51 to shift to the bottom of the plug 52 to ensure the normal cooperation between the test cavity 3 and the plug 52, and an adjustment component 8 connected to the clamp 4 is arranged on the mounting frame 1, which is used to control the clamp 4 to clamp and transport any product;

[0037] The shift assembly 6 includes a cylinder 61 arranged on the mounting frame 1, the end of the cylinder 61 is connected to the shift base 51, a linear slide rail 62 is arranged on the mounting frame 1, the shift base 51 is slidably arranged on the linear slide rail 62, and radial shifting members 7 are arranged on both sides of the mounting frame 1 for driving the adjacent plugs 52 to shift and adjust;

[0038] The shift assembly 6 includes a cylinder 61 arranged on the mounting frame 1, the end of the cylinder 61 is connected to the shift base 51, a linear slide rail 62 is arranged on the mounting frame 1, the shift base 51 is slidably arranged on the linear slide rail 62, and radial shifting members 7 are arranged on both sides of the mounting frame 1 for driving the adjacent plugs 52 to shift and adjust;

[0039] The radial displacement member 7 includes a second cylinder 71 disposed on the mounting frame 1, a sliding frame 72 is disposed at the end of the second cylinder 71, the plug 52 is disposed on the side of the sliding frame 72 close to the test cavity 3, a second linear guide rail 73 is disposed on the mounting frame 1, and the sliding frame 72 is slidably disposed on the second linear guide rail 73;

[0040] The adjustment assembly 8 includes a cylinder 3 81 arranged in the middle of the mounting frame 1, a mounting seat 82 is arranged at the end of the cylinder 3 81, the mounting seat 82 is slidably arranged on the mounting frame 1, a cylinder 4 83 is arranged on the mounting seat 82, a fixed seat 84 is arranged on the cylinder 4 83, and a clamping member 9 is arranged on the fixed seat 84 for driving the clamp 4 to clamp and position the product;

[0042] When in use, first, the test cavity 3 is connected to the airtight test equipment through a hose to ensure accurate airtightness test of the product. The turntable 2 is driven by an external device. When the product is transferred to the airtightness test station, it is transported by the clamp 4. The clamp 4 is driven by a two-way cylinder 91. The product to be tested is clamped by the clamp 1 41 and the clamp 2 42 to ensure stability during the test. The clamping process is as follows:

[0043] Initially, both test cavities 3 are empty. The following content is explained according to the normal clamping work. First, the product on the turntable 2 is clamped and placed in the empty test cavity 3 in the middle. The shift switching unit 5 starts to work. The shift base 51 is driven by the cylinder 1 61 and the linear guide rail 1 62. When the product in the test cavity 3 on one side is tested, the test cavity 3 that has completed the test is moved to the middle. At the same time, the other test cavity 3 that has just been loaded with the product is moved to the bottom of the fixture 4. Then, the fixture 4 is used to transfer the product on the test cavity 3 that has completed the test to the turntable 2. The turntable 2 continues to rotate and moves to the next station. The subsequent steps are analogous to each other. This can reduce the product handling time at the airtightness test station.

[0044] During the process, the position of the plug 52 is adjusted by the cylinder 2 71 and the linear guide 2 73 to ensure that the plug 52 is correctly matched with the test cavity 3 at the current position. Then, the fixture 4 releases the tested product and moves it away through the turntable 2 or other transfer mechanism. During the whole process, the adjustment component 8 realizes multi-directional adjustment of the fixture 4 on the mounting frame 1 through the coordinated work of the cylinder 3 81, the cylinder 4 83 and the bidirectional cylinder 91, thereby controlling the clamping and transfer of the product by the fixture 4.

The setting of the pressure sensors 10 is conducive to ensuring the normal operation of the cylinder 61, thereby ensuring the normal connection between the test cavity 3 and the plug 52, and improving the accuracy of the airtight test.
