Technical Field

[0001] The utility model relates to the technical field of filters, and particularly relates to a filter detection device. Background Art

[0002] A filter detection device is a device used to identify, capture, or filter specific signals or frequencies. It is usually used in the field of signal processing and can be applied in communication, electronic devices, or sensor systems to remove unwanted noise, interference, or signal components, thereby improving the system performance and accuracy. Such a device can adopt various technologies, including traditional electronic filters, digital signal processing, and advanced technologies such as deep learning.

[0003] After the existing filter products are produced, it is necessary to tap the filters to test their quality. Currently, it is usually the quality inspection operators who manually tap to generate the desired frequency band. However, the force with which the operators manually tap the filters may not be accurate. Excessive tapping force may cause physical damage to the filters, affecting their performance or even rendering them ineffective. At the same time, it may produce misleading test results, leading to incorrect evaluation of the filter performance. Content of the Utility Model

[0025] The following will describe in detail a filter detection device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0026] As Figure 1 、 Figure 4 、 Figure 5 and Figure 6 shown, a filter detection device includes a base plate 2, a moving assembly 12, and a fixing assembly 15. A plurality of moving assemblies 12 are provided at the top end of the base plate 2. The plurality of moving assemblies 12 include a fixed rod 121, a moving rod 122, a chute 123, and a through hole 124. A plurality of chutes 123 are provided on the side surface of the fixed rod 121. The fixed rod 121 is provided in a hollow state. A moving rod 122 is provided at the top end of the fixed rod 121. A through hole 124 is provided at the bottom of the moving rod 122.

[0027] The fixing assembly 15 includes a fixing plate 151, a limit turning knob 152, and a limit rod 153. A limit rod 153 is provided on one side of the fixing plate 151 close to the moving assembly 12. A limit turning knob 152 is provided at one end of the fixing plate 151 away from the limit rod 153. The limit rod 153 is used to penetrate the through hole 124 and limit the moving rod 122;

[0028] The moving component 12 can adjust its height according to filters of different specifications to ensure the fixation of the filters. Before the filter is placed on the top of the bottom plate 2, the top plate 14 is moved upward by the moving rod 122 to increase the space distance between the top plate 14 and the bottom plate 2. Subsequently, the moving rod 122 is adjusted according to the size of the filter. Finally, the limiting rod 153 passes through the through hole 124 at the bottom end of the moving rod 122 to fix the moving rod 122, and at the same time, the stability of the filter is ensured.

[0029] At the connection between the fixing plate 151 and the limiting rod 153 in the fixing component 15, there is a clamping interface. Through the clamping hole, the limiting rod 153 can be clamped with the fixing plate 151, and at the same time, the limiting distance for the moving rod 122 is ensured. When the limiting rod 153 limits the moving rod 122, to prevent the fixing plate 151 from moving in the second notch 132, by rotating the limiting knob 152, the connection at its end is expanded to squeeze the inner wall of the bottom plate 2, thereby ensuring the stability of the fixing component 15.

[0030] Such as Figure 1 、 Figure 2 and Figure 3 As shown in, on both sides of the inner wall of the bottom plate 2, there are notches 13, and the notch 13 includes a first notch 131, a second notch 132, and a third notch 133. The same side of the first notch 131 and the second notch 132 is penetrated by the third notch 133, and the fixing plate 151 is placed in the third notch 133.

[0031] At the top end of the moving rod 122, there is a top plate 14, and the top plate 14 is fixedly connected to the moving rod 122.

[0032] One side of the outer wall of the bottom plate 2 is connected to one end of the second connecting rod 5, and the other end of the second connecting rod 5 is provided with a rotating motor 9. Through the rotating motor 9, the bottom plate 2 can be rotated, and at the same time, the rotation direction of the fixed filter can be changed.

[0033] At the bottom end of the rotating motor 9, there is a support plate 10, and at one end of the support plate 10 away from the rotating motor 9, there is a band tester 11. By knocking and monitoring the generated vibration frequency, it can be detected whether the filter is operating within the predetermined frequency band to ensure that its performance meets the specifications. Through the sound wave generated by knocking, it can be detected whether the material used for the filter meets the quality standards to prevent the use of defective or counterfeit materials.

[0034] On the side of the outer wall of the bottom plate 2 away from the second connecting rod 5, there is a first connecting rod 4, and at one end of the first connecting rod 4 away from the bottom plate 2, there is a bearing 3.

[0035] Both the bearing 3 and the support plate 10 are fixedly connected to the inner wall of the frame 1. A sliding member 6 is provided on the top wall of the frame 1, and the bottom end of the sliding member 6 is slidably connected to a cylinder 7. The cylinder 7 is used to control the rubber hammer 8 to strike. By striking, it can be used to detect whether there are mechanical failures or material defects in the filter, because failures may cause a decline in the performance of the filter. The percussion test is a non-destructive testing method that will not damage the filter, and at the same time, it can provide information about its quality and performance.

[0036] In the technical solution provided by the present utility model, the moving assembly 12 can adjust the height according to filters of different specifications and sizes to ensure the fixation of the filter. Before the filter is placed on the top end of the bottom plate 2, the top plate 14 is moved upward through the moving rod 122 to increase the space distance between the top plate 14 and the bottom plate 2. Subsequently, the moving rod 122 is adjusted according to the size of the filter. Finally, the limiting rod 153 passes through the through hole 124 at the bottom end of the moving rod 122 to fix the moving rod 122, and at the same time, the stability of the filter is also ensured.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
