Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter testing device. Background Technology

[0002] In related technologies, filters need to undergo electrical testing during the manufacturing process. Currently, this is usually done by using probes to contact the filter pins to complete the electrical test.

[0003] However, using probes is not only prone to wear and requires frequent replacement, but also, during testing, the impact force when they come into contact with the filter pins can easily cause the filter pins to bend and deform, thus increasing the failure rate of the filter. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a filter testing device that can replace probes to test the pins of the filter, thereby improving product yield.

[0005] The objective of this utility model is achieved through the following technical solution: This application provides a filter testing device, comprising: a driving unit; a clamping assembly including a first moving block and a second moving block, the first moving block and the second moving block being respectively disposed on the driving unit, the driving unit being used to drive the first moving block and the second moving block to move towards each other or away from each other; and a detection assembly including a first limiting block, a first gold finger, a second limiting block and a second gold finger, the first limiting block being disposed on the first moving block, the first gold finger being disposed on the first limiting block, the second limiting block being disposed on the second moving block, and the second gold finger being disposed on the second limiting block.

[0006] The first limiting block has a first slot, and the first gold finger is disposed in the first slot.

[0007] The second limiting block has a second slot, and the second gold finger is disposed in the second slot.

[0008] The first moving block has a first inclined surface.

[0009] The second moving block has a second inclined surface.

[0010] There are two of the first moving blocks.

[0011] The number of the first moving blocks is the same as the number of the first limiting blocks.

[0012] There are two of the second moving blocks.

[0013] The number of the second moving blocks is the same as the number of the second limiting blocks.

[0014] There is an angle between the plane containing the first inclined plane and the plane containing the second inclined plane.

[0015] Compared with the prior art, the present invention has at least the following advantages: The drive unit moves the first and second moving blocks in opposite directions, which in turn moves the first and second gold fingers on the first and second limiting blocks in opposite directions. This causes the first and second gold fingers to rest on the filter pins, thus completing the electrical test. This method replaces the probe method for electrical testing of the filter pins, eliminates the need for frequent gold finger replacements, and ensures that the gold fingers do not exert significant impact on the filter pins during the test, preventing deformation of the filter pins. Attached Figure Description

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0017] Figure 1 This is a schematic diagram of the filter testing device in one embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the first gold finger and the first limiting block in one embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of the second gold finger and the second limiting block in one embodiment of the present invention. Detailed Implementation

[0018] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0019] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] During the manufacturing process, filters require electrical testing, which is currently typically performed using probes that contact the filter pins. However, probes are prone to wear and require frequent replacement. Furthermore, the impact force during testing can easily bend and deform the filter pins, thus increasing the filter's defect rate.

[0022] To address the aforementioned issues, this application provides a filter testing device that can replace probes to test the pins of a filter, thereby improving product yield.

[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] See Figure 1 A filter testing device includes a driving unit 330, a clamping assembly 340, and a detection assembly 350. The clamping assembly 340 includes a first moving block 341 and a second moving block 342, which are respectively disposed on the driving unit 330. The driving unit 330 is used to drive the first moving block 341 and the second moving block 342 to move towards each other or away from each other. The detection assembly 350 includes a first limiting block 351, a first gold finger 352, a second limiting block 353, and a second gold finger 354. The first limiting block 351 is disposed on the first moving block 341, the first gold finger 352 is disposed on the first limiting block 351, the second limiting block 353 is disposed on the second moving block 342, and the second gold finger 354 is disposed on the second limiting block 353.

[0025] It should be noted that the driving unit 330 is a clamping cylinder. The clamping cylinder drives the first moving block 341 and the second moving block 342 to move towards each other, thereby causing the first gold fingers 352 and the second gold fingers 354 on the first limiting block 351 and the second limiting block 353 to move towards each other. This allows the first gold fingers 352 and the second gold fingers 354 to rest on the filter pins to complete the electrical test. This method replaces the probe method for electrical testing of the filter pins, eliminates the need for frequent replacement of the gold fingers, and ensures that the gold fingers do not exert significant impact on the filter pins during the test, preventing deformation of the filter pins. Specifically, this application provides two of each of the first moving blocks 341 and the second moving blocks 342. The number of first moving blocks 341 is the same as the number of first limiting blocks 351, and the number of second moving blocks 342 is the same as the number of second limiting blocks 353. The number of first gold fingers 352 and the number of second gold fingers 354 are both multiple.

[0026] See Figure 2 In one embodiment, a first slot 3511 is provided on the first limiting block 351, and a first gold finger 352 is disposed in the first slot 3511.

[0027] It is understandable that the first slot 3511 is used to limit the first gold finger 352.

[0028] See Figure 3 In one embodiment, a second slot 3531 is provided on the second limiting block 353, and a second gold finger 354 is disposed in the second slot 3531.

[0029] It is understandable that the second slot 3531 is used to limit the second gold finger 354.

[0030] See Figure 1 In one embodiment, the first moving block 341 has a first inclined surface 3411.

[0031] Specifically, the second moving block 342 has a second inclined surface 3421.

[0032] More specifically, there is an angle between the plane containing the first inclined plane 3411 and the plane containing the second inclined plane 3421.

[0033] It should be noted that by setting the first inclined surface 3411 and the second inclined surface 3421, the contact area between the first gold finger 352 and the second gold finger 354 and the filter pin can be increased during the electrical test.
