Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Please see Figure 1-4 In this utility model: a fully automatic RF testing fixture includes a main body 1, the front of which is open, and a cover plate 2 is hinged to the front of the main body 1. A placement plate 3 is installed on the inner bottom wall of the main body 1, and a clamping mechanism 4 is provided on the placement plate 3. Two cylinders 5 are fixedly connected to the inner top wall of the main body 1, and a lifting plate 6 is fixedly connected between the two cylinders 5. A moving frame 7 is slidably connected to the inner side of the lifting plate 6, and a cylinder 8 is fixedly connected between the moving frame 7 and the inner side of the lifting plate 6. The inner side of the moving frame 7 is slidably connected to... There is a movable block 9, and a cylinder 10 is fixedly connected between the left side of the movable block 9 and the inner side of the movable frame 7. A test interface 11 is installed at the bottom of the movable block 9. The clamping mechanism 4 includes a slide 401, which is opened at the top of the shelf 3. A lead screw 402 is rotatably connected to the inner wall of the slide 401. A motor 403 is fixedly connected to the right side of the shelf 3. The output shaft of the motor 403 passes through the shelf 3 and is fixedly connected to the lead screw 402. Two clamping plates 404 are threadedly connected to the lead screw 402.
[0025] In this invention, during use, firstly, the cover plate 2 of the main body 1 is opened. Then, the user places the product to be tested with its interface facing upwards on the top of the shelf 3. Next, the user turns on motor 403 to rotate the lead screw 402. Because the lead screw 402 has a double thread, its rotation causes the bottoms of the two clamping plates 404 to slide along the slide groove 401 and the top of the shelf 3. After both clamping plates 404 contact the product, the product is clamped and fixed. Then, the user can move the moving frame 7 back and forth by turning on cylinder 8, thereby changing the front and rear positions of the test interface 11 and the product interface. The user can also move the moving block 9 left and right inside the moving frame 7 by turning on cylinder 10, thereby changing the left and right positions of the test interface 11 and the product interface. By controlling cylinders 8 and 10, the test interface 11 can be adjusted to align with the product interface. After the test interface 11 is aligned, the user can lower the lifting plate 6 by activating cylinder 5. The lowering plate 6 will move the test interface 11 toward the product. After the test interface 11 is inserted into the product interface, the connection between the product and the main body 1 is completed. Then, the user closes the cover 2 to test the product. After the test is completed, the user opens the cover 2 and simultaneously reverses the motor 403 and cylinder 5 to disconnect the product from the main body 1 and stop clamping the product. The user can then open the cover 2 to remove the product from the main body 1. The process is very convenient and quick, effectively reducing the difficulty of testing products and improving the practicality of the device.
[0026] Please see Figure 1 and 2 The bottom of the shelf 3 is fixedly connected to two support blocks 12. Each support block 12 is fitted with a track 13 that is slidably connected to it. The bottom of each track 13 is fixedly connected to the inner wall of the main body 1. The bottom of the shelf 3 is provided with a drive mechanism 14 for driving the shelf 3 to move back and forth. The drive mechanism 14 includes a second motor 141. The output shaft of the second motor 141 is fixedly connected to a gear 142. The inner side of the main body 1 is fixedly connected to a rack 143. The inner side of the rack 143 is provided with teeth that mesh with the gear 142.
[0027] In this invention, the cooperation between the track 13 and the support block 12 allows the shelf 3 to slide on the inner bottom wall of the main body 1. By turning on the motor 141, the user can drive the gear 142 to move along the teeth on the inner side of the rack 143, thereby changing the position of the shelf 3 and driving the shelf 3 toward the front of the main body 1, which makes it very convenient for the user to operate the product.
[0028] Please see Figure 2-4 The movable block 9 has a cavity 15, a fan 16 is embedded on the right side of the cavity 15, and an air outlet pipe 17 is connected to the inner wall of the cavity 15.
[0029] In this utility model, when the main body 1 is connected to the product, the user first moves the air outlet pipe 17 to the top of the product's interface. Then, the user turns on the fan 16 to send air into the cavity 15. The air is then sprayed from the air outlet pipe 17 toward the product's interface, thereby blowing away the dust on the product's interface and achieving the effect of cleaning the product's interface. This effectively avoids the impact of dust on the connection between the main body 1 and the product, and improves the effect of product testing.
[0030] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
