[0023] 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.

[0024] Example 1

[0025] like Figures 1-5 As shown, a filter insertion loss testing and positioning device includes...

[0026] The first positioning mechanism 1 for positioning both ends of the filter includes a first cylinder 11, a movable seat 14, a fixed shaft 15 disposed on the movable seat 14, and a plurality of first positioning members 17 hinged on the fixed shaft 15. A plurality of pairs of clamping pieces 18 are slidably disposed on the movable seat 14. Each pair of clamping pieces 18 is located on both sides of the first positioning member 17. Each pair of clamping pieces 18 is driven to move towards each other by a threaded rod 19 disposed on the movable seat 14 to clamp the first positioning member 17. The movable seat 14 is driven by the first cylinder 11 to approach / leave the filter.

[0027] The second positioning mechanism 2 is used to position the two sides of the filter.

[0028] This solution sets up several movable first positioning elements 17, which can be pre-adjusted according to the shape of the filter end face. The adjusted first positioning elements 17 can well adapt to the end face positioning task of the filter. After adjustment, the first positioning elements 17 are clamped and fixed by the clamping piece 18, so that each first positioning element 17 is relatively fixed with the moving seat 14. Then, the filter is positioned by the movement of the moving seat 14, which improves the compatibility of the positioning device.

[0029] The positioning device also includes a lifting base 4 for mounting the first positioning mechanism 1 and the second positioning mechanism 2. By setting the lifting base 4 to mount the two positioning mechanisms, it can be raised and lowered as needed to position the filter on the production line.

[0030] The end surface of the lifting base 4 is provided with a first hinge seat 12, and a first actuating member 13 is hinged on the first hinge seat 12. One end of the first actuating member 13 is fixed to the moving seat 14, and the other end is used to be pushed by the first cylinder 11. This solution further proposes a method in which the first cylinder 11 drives the moving seat 14. By setting the first hinge seat 12 for driving, when the first cylinder 11 extends, the two moving seats 14 move inward to position the filter.

[0031] Each first positioning element 17 is provided with a torsion spring 16 on its shaft. The plate-shaped first positioning element 17 is used to adapt to the complex end face of the filter by adjustment. Before each batch of products is tested, the position of each first positioning element 17 needs to be set. The torsion spring 16 can press the first positioning element 17 tightly against the end face of the filter, which helps with adjustment.

[0032] The surface of the threaded rod 19 is provided with threads corresponding to each pair of clamping pieces 18, and the thread directions of each pair of clamping pieces 18 are opposite. The moving seat 14 is provided with a driving part 110 for driving the threaded rod 19 to rotate. By rotating the threaded rod 19, each pair of clamping pieces 18 is brought closer to each other, which achieves the effect of clamping and fixing the first positioning member 17.

[0033] The second positioning mechanism 2 includes a second cylinder 21 and a second hinge seat 22 mounted on the lifting base 4. The second hinge seat 22 is hinged to a second actuating member 23. One end of the second actuating member 23 is fixedly connected to a second positioning member 24, and the other end is used to be pushed by the second cylinder 21. The second positioning mechanism 2 is prior art and is used to perform preliminary positioning of the filter by contacting the two flat surfaces of the filter.

[0034] The lower surface of the lifting base 4 is also provided with a pressing device 3, which includes a third cylinder 31, a track seat 32 provided at the output end of the third cylinder 31, and a pressing block 33 horizontally slidably provided on the track seat 32. The sliding direction of the pressing block 33 is towards the first positioning mechanism 1 at both ends. The pressing device 3 is provided to vertically press and fix the filter. The purpose of providing the track seat 32 and the pressing block 33 is to allow the filter to be pushed by the first positioning mechanism 1 after it is pressed. When positioning a small filter, the first positioning mechanism 1 and the second positioning mechanism 2 may interfere with each other when they move inward. Therefore, for a small filter, the pressing device 3 replaces the second positioning mechanism 2 to prevent the filter from moving to both sides and to make the second positioning mechanism 2 move away before the first positioning mechanism 1 operates.

[0035] The specific implementation method is as follows: the second positioning mechanism 2 is adjusted according to different filters. First, the filter is placed at the position that needs to be positioned. This position is used to facilitate port docking of the testing device. Then, the first cylinder 11 pushes the first actuating member 13 to move the moving seat 14 toward the filter. Several first positioning members 17 are attached to the end face of the filter. Then, the driving part 110 drives the clamping plate 18 to clamp several second positioning members 17. After fixing, it can be put into use.

[0036] During testing, the filter is located on the transmission platform 5. The second positioning mechanism 2 positions the filter on the centerline of the transmission platform 5. Specifically, the second cylinder 21 pushes the second actuating component 23, which in turn drives the second positioning component 24 to move inward, contacting the side of the filter and pushing the filter to coincide with the centerline. Then, the first positioning mechanism 1, which has been adjusted to fit the shape of both ends of the filter, is activated to move the filter to a fixed position. Then, one of the first positioning mechanisms 1 is raised, creating space for the external automated testing device to dock with the port of the filter. After docking, it also fixes the end of the filter. Then, the other positioning mechanism 1 is also raised, and the other end of the filter is docked with the testing device.

[0037] For small filters, after the second positioning mechanism 2 positions the filter, the third cylinder 31 drives the track seat 32 to press down, so that the pressure block 33 presses the upper surface of the filter. Rollers can be set between the track seat 32 and the pressure block 33 to roll, so that the pressure block 33 can restrict the filter from moving to the sides, but does not restrict it from moving to both ends. Then, the first positioning mechanism 1 positions both ends. After positioning, the test is carried out in the above manner.

[0038] 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.
