[0036] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0037] A filter is an electronic component that selects the frequency of a signal and is widely used in the fields of communications, audio, video, etc. A filter is also provided on the mainboard of the air conditioner to suppress interference signals input on the AC power line and various interferences induced on the signal transmission line. The filter is composed of a skeleton, enameled wire, a magnetic core, and pins. The magnetic core is usually made of manganese-zinc ferrite. The magnetic core is prone to cracking after the filter is transported and circulated. Therefore, the existing filters need to be performance tested before use to determine whether the quality of the filter meets the standards. The existing filter performance test is usually conducted manually. The worker takes the filter out of the packaging box and puts it into the testing instrument for testing. After the test is completed, the filter that meets the quality standards is put back into the packaging box. This testing method is inefficient and prone to misdetection and missed detection, which is not conducive to the control of the filter and is not conducive to improving production efficiency. Based on this, the present application provides a filter testing device.

[0038] Example 1

[0040] During use, the filter to be tested is placed on the first lifting tray 22, and the first lifting tray 22 rises to send the filter to be tested to a position flush with the surface of the test host 1, and then the material transfer mechanism clamps the filter to be tested and sends the filter to the test clamp 13 for testing, and the test result of the filter of the test host 1 is obtained. If the test result meets the standard, the material transfer mechanism will send the tested filter to the second lifting tray 33 of the material receiving mechanism 3; if the test result does not meet the standard, the material transfer mechanism will send the tested filter to the recovery box 14. The device can realize automatic testing of the filter without manually unpacking and packing the filter, which can improve the test efficiency of the filter and reduce the situation of misdetection and missed detection of the filter.

[0041] More specifically, the test device of the present application is used in a production workshop of an air conditioner. Before the filter is installed on the mainboard of the air conditioner, the filter is tested by the test device to determine whether the quality of the filter meets the standard.

[0042] The test process is to contact the pin of the filter with the test clamp 13, and the test clamp 13 is provided with a test circuit. When the pin of the filter contacts the test circuit, the test host 1 can judge whether the quality of the filter meets the standard. The specific judgment standard is that when the magnetic core of the filter is broken, the inductance of the filter will decrease. Therefore, the test host 1 judges whether the quality of the filter meets the standard by judging the inductance of the filter.

[0043] More specifically, the top of the test host 1 is a test working surface, and the test clamping plate 13 and the material moving mechanism are arranged on the top of the test host 1 .

[0098] Example 8

[0099] like Figure 6 As shown, this embodiment provides a filter testing method, which is implemented based on the testing device as described above; the testing device includes a testing host 1, on which a material moving mechanism and a testing clamp 13 are provided; a feeding mechanism 2 and a material receiving mechanism 3 are provided on one side of the testing host 1, and a feeding plate mechanism 4 is also provided on one side of the material receiving mechanism 3.

[0100] The feeding mechanism 2 is provided with a first lifting tray 22 for conveying the material to be tested, and the receiving mechanism 3 is provided with a second lifting tray 33 for recovering the material to be tested. Both the first lifting tray 22 and the second lifting tray 33 can move along the height direction of the test host 1.

[0101] A tray delivery mechanism 4 is also provided on one side of the material receiving mechanism 3. A third lifting tray 43 and a first push plate 44 are provided in the tray delivery mechanism 4. The third lifting tray 43 can be raised and lowered on one side of the tray delivery mechanism 4. The first push plate 44 is provided above the third lifting tray 43 to transfer the material tray in the third lifting tray 43 to the material receiving mechanism 3. More preferably, the top of the test host 1 is a test working surface. The first lifting tray 22 delivers the filter to be tested to the test working surface, and the second lifting tray 33 receives the filter that has been tested and the test results meet the standards on the test working surface. Sensors for obtaining the tray position are provided on the material feeding mechanism 2 and the material receiving mechanism 3.

[0102] The test method comprises the following steps:

[0103] S100, the material transfer mechanism obtains the material to be tested on the first lifting tray 22, and places the material to be tested on the test clamping plate 13 for testing;

[0104] S200, obtaining test results, and determining whether the test results meet the standards;

[0105] S300: If yes, place the tested material on the second lifting tray 33; if no, recycle the substandard material.

[0106] The working process of the test method of this application is described in detail below:

[0107] The filter to be tested is placed on the first lifting tray 22, and the empty tray is placed on the second lifting tray 33. The entire device is started, and the driving device of the feeding mechanism 2 drives the first lifting tray 22 to rise. When the sensor detects that the first lifting tray 22 rises to a position flush with the top of the test host 1, the driving device of the feeding mechanism 2 stops running. The material transfer mechanism grabs the filter to be tested on the first lifting tray 22 and places it on the test clamp 13 for testing. If the test result of the tested filter is up to standard, it is placed on the second lifting tray 33. If the test result is not up to standard, it is placed in the recycling box 14. When the tray on the second lifting tray 33 is full of filters, the second lifting tray 33 descends to send out the full tray. The tray feeding mechanism 4 sends the empty tray into the second lifting tray 33 again, and the cycle is repeated to test the filter. In addition, the test host 1 can record relevant test data and automatically upload the data to the EMS system.

[0108] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0109] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0110] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
