[0017] See also Figure 1-5 The utility model provides a set-top box testing device, comprising a test bench 1, a conveying mechanism 7 and a controller. The upper end surface of the test bench 1 is provided with a first retractor 2, a set-top box box 3 and a set-top box fixing plate 5 in sequence from left to right. The set-top box box 3 is used to place a plurality of set-top boxes 4. The cross-sectional size of the set-top box box 3 can only pass through one set-top box 4. The plurality of set-top boxes 4 are stacked up and down in the set-top box box 3. The lower end and left and right ends of the set-top box box 3 are provided with openings 3.1, that is, the lowest set-top box 4 is in contact with the upper end surface of the test bench 1. The openings 3.1 at the left and right ends are only for one set-top box 4 to enter and exit, that is, the height and width of the openings 3.1 are slightly larger than the height of the set-top box 4. The height and width of the first retractor 2 are opposite to the opening 3.1 at the left end, and the set-top box 4 in the set-top box body 3 is pushed onto the set-top box fixing plate 5 through the opening 3.1. The set-top box fixing plate 5 is provided with a limiting mechanism 6 for the set-top box 4, and the left and right ends of the limiting mechanism 6 are respectively provided with an inlet and an outlet corresponding to the opening 3.1, that is, the set-top box 4 pushed out from the set-top box body 3 can enter the limiting mechanism 6 from the inlet and be pushed out of the limiting mechanism 6 from the outlet. The front and rear sides of the set-top box fixing plate 5 are respectively provided with a second retractor 9 and a test terminal block 8, and the output end of the second retractor 9 is connected to the set-top box fixing plate 5 to push the set-top box fixing plate 5 to slide close to or away from the test terminal block 8.

The conveying mechanism 7 is disposed at the right end of the test bench 1 and corresponds to the exit of the limiting mechanism 6 . The conveying mechanism 7 , the first retractor 2 , the second retractor 9 , the first sensor 10 and the second sensor 11 are all connected to the controller.

[0018] In the specific implementation of the utility model, the limiting mechanism 6 of the set-top box 4 includes four inverted L-shaped limiting plates 6.1, and the inverted L-shaped limiting plates 6.1 are arranged at the four corners of the set-top box fixing plate 5. One side plate of the inverted L-shaped limiting plate 6.1 is vertically arranged on the set-top box fixing plate 5, and the other side plate is horizontally arranged at the top of the vertical side plate. The side plates at the top extend toward the inside of the set-top box fixing plate 5, but there is a spacing. An inlet or an outlet is formed between the two limiting plates 6.1 at the front and rear ends. The inlet or the outlet is slightly larger than the set-top box 4 and can accommodate the set-top box 4 to slide through. The limiting plates 6.1 at the left and right ends also have a spacing, which exposes the port of the set-top box 4 for easy plugging and unplugging.

[0019] The test bench 1 of the utility model is provided with a groove, and the set-top box fixing plate 5 slides in the groove, and the upper end surface of the set-top box fixing plate 5 is flush with the upper end surface of the test bench 1.

[0020] The first telescopic device 2 and the second telescopic device 9 of the utility model adopt pneumatic cylinders. The first telescopic device 2 adopts the first sensor 10 and the second sensor 11 to control the first stroke. The second stroke is the final stroke, which is controlled by the controller after the second telescopic device 9 is completed. The telescopic end of the first telescopic device 2 and the set-top box 4 are roughly the same height, that is, when the telescopic end pushes out the lowermost set-top box 4, the telescopic end can support the upper set-top box 4. The telescopic end can be covered with a rubber sleeve. The upper end surface of the test bench 1 corresponding to the set-top box box 3 and the set-top box fixing plate 5 are provided with a rubber pad to protect the set-top box 4. The telescopic stroke of the first telescopic device 2 is set according to the length or width of the set-top box 4, the length of the limit mechanism 6, etc., so that the set-top box 4 can be pushed from the set-top box box 3 to the limit mechanism 6 and then to the conveying mechanism 7. The test terminal block 8 is provided with a test terminal corresponding to the interface of the set-top box 4, and the test terminal block 8 is fixed on the test bench 1 by bolt connection. The conveying mechanism 7 adopts a belt conveyor, and may also adopt a plate conveyor. The conveying plane of the conveying mechanism 7 is flush with the upper end surface of the test bench 1 .

[0021] During the specific operation of the utility model, a plurality of set-top boxes are stacked up and down in a set-top box body, and the first telescope pushes the set-top box at the bottom of the set-top box body into the set-top box limiting mechanism. When pushing out, the telescopic end of the first telescope supports the upper set-top box, and the first stroke of the first telescope is controlled by a sensor. After completion, the second telescope slides the set-top box fixing plate close to the test terminal block to complete the post-plugging test of the test terminal and the interface, and then the second telescope contracts to slide the set-top box fixing plate away from the test terminal block to pull out the test terminal. After contracting into place, the first telescope continues the second stroke to push the set-top box in the limiting mechanism to the conveying mechanism to enter the next process.
