Description

Technical Field

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

[0002] A filter is a frequency-selective device specifically designed to allow signals of specific frequencies to pass through while significantly suppressing other frequencies. A common type of filter is the microwave filter, which selectively selects the frequency of microwave signals. The capacitors, inductors, and circuit boards of microwave filters are typically fixed by soldering. However, incomplete soldering can lead to cold solder joints, reducing the filter's lifespan. Therefore, after production, testing equipment is usually used to photograph and magnify the internal circuitry of microwave filters to visually confirm whether the circuitry is properly soldered.

[0003] Patent CN216386839U discloses "a testing device for filter production, including a mounting base, a support plate, an observation plate, and a flexible rod disposed at one end of the observation plate; this utility model, through the combined action of the display screen and the camera, can conveniently inspect the internal circuit cell connection parts of the filter that has been produced, under the combined action of the support frame and the observation plate. At the same time, the camera captures and displays the images on the screen, thereby improving the efficiency and accuracy of the entire filter production testing process."

[0004] Although the existing technology described above can be used to photograph, magnify, and inspect the circuit part of the filter, the inspection requires placing the filter in the middle of the carrier plate so that the camera can photograph the filter in the middle of the carrier plate. Then, the abutment block is moved to clamp the filter. However, manual placement can easily cause the filter to shift in position, and the filter's position may need to be adjusted frequently during subsequent shooting. Frequent adjustment of the filter's position is inconvenient, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a microwave filter detection device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A microwave filter testing device includes a base plate, a support plate mounted on top of the base plate, a drive mechanism mounted on top of the base plate for driving the support plate to rise and fall, a testing mechanism mounted on top of the base plate for photographing and magnifying the circuit part of the filter on top of the support plate for testing, and an adjustment mechanism mounted on top of the support plate. An annular barrier is fixedly provided at the top edge of the support plate. The adjustment mechanism includes two U-shaped push plates slidably disposed on both sides of the inner wall of the annular barrier, a movable crossbar fixed on one side of the U-shaped push plates with one end penetrating and extending to the outside of the annular barrier, and two fixed vertical plates fixed on both sides of the top of the base plate and cooperating with the bottom of one end of the movable crossbar. A guide slope is provided between the movable crossbar and the fixed vertical plates for simultaneously pushing the two U-shaped push plates toward the center of the support plate when the support plate continues to move downward.

[0008] As a further optimization of this utility model, the driving mechanism includes a hydraulic cylinder fixedly installed between the top of the base plate and the bottom of the support plate.

[0009] As a further optimization of this utility model, a fixing frame is fixedly provided on one side of the top of the base plate, and a top plate located directly above the bearing plate is fixedly provided at the top of the fixing frame.

[0010] As a further optimization of this utility model, the detection mechanism includes a camera fixedly installed at the center of the bottom of the top plate, and a display screen fixedly installed on the outer wall of the fixing frame for magnifying and displaying the images captured by the camera. A ring-shaped fill light for supplementing the camera is fixedly installed at the bottom edge of the top plate.

[0011] As a further optimization of this utility model, two sets of tension springs are fixedly provided between the two sides of the inner wall of the annular enclosure and the two U-shaped push plates, and a buffer pad is fixedly provided on the side of the U-shaped push plate away from the tension springs.

[0012] As a further optimization of this utility model, a cleaning sponge is fixedly installed on the bottom side of the U-shaped push plate near the tension spring, which abuts against the top of the support plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The testing mechanism can photograph and magnify the circuit parts of filters such as microwave filters on the top of the carrier plate for testing. The drive mechanism can move the carrier plate up and down, which facilitates the testing of filters of different sizes and specifications. When the carrier plate continues to move down, under the guidance of the guide slope and the transmission of the movable crossbar, the filter can be pushed towards the center of the carrier plate by two U-shaped push plates, thereby positioning and centering the filter, reducing the frequency of adjusting the filter position during subsequent shooting, which is more convenient.

[0015] 2. The tension of the spring can pull the U-shaped push plate towards the ring-shaped enclosure side after the support plate continues to move upward, so that the U-shaped push plate can be used to adjust other filters to be tested. After the U-shaped push plate moves, it can also move the cleaning sponge. The moved cleaning sponge can wipe and clean the top part of the support plate, reducing the cleaning intensity of the support plate for the staff later. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1-3 As shown, a microwave filter testing device includes a base plate 1, a support plate 11, a driving mechanism, a testing mechanism, and an adjustment mechanism. The support plate 11 is installed on the top of the base plate 1, and the driving mechanism is installed on the top of the base plate 1 and is used to drive the support plate 11 to move up and down. The driving mechanism includes a hydraulic cylinder 12 fixedly installed between the top of the base plate 1 and the bottom of the support plate 11. The hydraulic cylinder 12 can connect the base plate 1 and the support plate 11, and the extension and retraction of the hydraulic cylinder 12 will drive the support plate 11 to move up and down.

[0023] like Figure 1As shown, the detection mechanism is installed on the top of the base plate 1 and is used to photograph and magnify the circuit part of the filter on the top of the carrier plate 11 for detection. A fixing frame 13 is fixed on one side of the top of the base plate 1, and a top plate 14 located directly above the carrier plate 11 is fixed on the top of the fixing frame 13. The detection mechanism includes a camera 2 fixedly installed at the bottom center of the top plate 14, and a display screen 21 fixed on the outer wall of the fixing frame 13 for magnifying and displaying the image captured by the camera 2. A ring light 22 for supplementing light to the camera 2 is fixed at the bottom edge of the top plate 14. The fixing frame 13 can connect the base plate 1 and the top plate 14, and the top plate 14 can support and fix the camera 2 and the display screen 21.

[0024] After the camera 2 is running, it can capture, magnify, and record the circuit parts of the microwave filter and other filters on the carrier plate 11, and project the captured and magnified images onto the display screen 21 for display. The inspectors can observe from the display screen 21 whether there are any defects in the soldering of the microwave filter and other filters, thereby inspecting the microwave filter and other filters. The hydraulic cylinder 12 in the drive mechanism can drive the carrier plate 11 to move up and down, which facilitates the inspection mechanism to inspect filters of different sizes and specifications. The ring light 22 can provide supplementary lighting for the camera 2 to improve the clarity of the images.

[0025] like Figure 1-2 As shown, the centering mechanism is installed on the top of the support plate 11. An annular barrier 3 is fixedly provided at the top edge of the support plate 11. The centering mechanism includes two U-shaped push plates 31 that are slidably disposed on both sides of the inner wall of the annular barrier 3, a movable crossbar 32 fixed on one side of the U-shaped push plates 31 and extending through and to the outside of the annular barrier 3, and two fixed vertical plates 33 fixed on both sides of the top of the base plate 1 and abutting against the bottom of one end of the movable crossbar 32. A guide slope 34 is provided between the movable crossbar 32 and the fixed vertical plates 33 for guiding the two U-shaped push plates 31 to push towards the center of the support plate 11 simultaneously when the support plate 11 continues to move downward. The annular barrier 3 can block the edge of the support plate 11, making it difficult for microwave filters and other filters to fall off the top of the support plate 11. The annular barrier 3 can also support the movable crossbar 32 and other components.

[0026] As the support plate 11 continues to move downward, it will drive the movable crossbar 32 and other components to move downward as well. At this time, the movable crossbar 32 will abut against the top of the fixed vertical plate 33. As the support plate 11 continues to move downward, with the guidance of the guide slope 34, the movable crossbars 32 on both sides of the annular enclosure 3 will move inward to the inside of the annular enclosure 3. After the movable crossbars 32 move, they will use two U-shaped push plates 31 to push the filter towards the middle of the support plate 11 at the same time, thereby positioning and centering the filter and reducing the frequency of adjusting the filter position during subsequent shooting.

[0027] like Figure 1-3As shown, two sets of tension springs 35 are fixed between the inner walls of the annular enclosure 3 and the two U-shaped push plates 31. A buffer pad 36 is fixed on the side of the U-shaped push plate 31 away from the tension springs 35. The buffer pad 36 can be made of rubber or other materials with a buffering effect. When the two U-shaped push plates 31 push the filter towards the middle of the support plate 11 at the same time, the buffer pad 36 can buffer and protect the filter, so that the two U-shaped push plates 31 are not likely to damage the filter. The tension of the tension springs 35 can pull the U-shaped push plates 31 back to the original position after the support plate 11 continues to move upward, so that the U-shaped push plates 31 can be adjusted to other filters to be tested in the future.

[0028] like Figure 1-3 As shown, a cleaning sponge 37 is fixedly installed on the bottom side of the U-shaped push plate 31 near the tension spring 35, and it abuts against the top of the support plate 11. When the U-shaped push plate 31 moves, it can drive the cleaning sponge 37 to move as well. The cleaning sponge 37 can wipe and clean the top part of the support plate 11 after it moves, reducing the cleaning intensity of the support plate 11 for the staff later.

[0029] It should be noted that, in the use of this microwave filter testing device, the microwave filter to be tested is first placed on the top of the support plate 11. Then, the hydraulic cylinder 12 is shortened to drive the support plate 11 to move downward. As the support plate 11 continues to move downward, it will drive the movable crossbar 32 and other components to move downward as well. At this time, the movable crossbar 32 will abut against the top of the fixed vertical plate 33. As the support plate 11 continues to move downward, with the guidance of the guide slope 34, the movable crossbars 32 on both sides of the annular enclosure 3 will move inward to the inside of the annular enclosure 3. After the movable crossbars 32 move, they will use two U-shaped push plates 31 to push the filter towards the middle of the support plate 11 at the same time, thereby positioning and centering the filter and reducing the frequency of adjusting the filter position during subsequent shooting.

[0030] Then, the hydraulic cylinder 12 is extended to move the support plate 11 upward, so that the filter after being centered on the top of the support plate 11 can get close to the camera 2 on the top. After the camera 2 is running, it can take pictures and magnify the circuit parts of the microwave filter and other filters on the support plate 11, and project the pictures and magnified images onto the display screen 21 for display. The inspectors can observe from the display screen 21 whether there are any problems with the soldering of the circuit parts of the microwave filter and other filters, so as to inspect the microwave filter and other filters.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
