Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1-5An integrated circuit test base shown in the figure includes a fixed rod 3 fixedly installed on the top of a base 1. A rotating tube 2 is movably sleeved on the fixed rod 3, and the rotating tube 2 is rotatably connected to the base 1. In order to rotatably install the rotating tube 2 on the base 1, an annular groove is formed on the top of the base 1. The bottom end of the rotating tube 2 extends into the annular groove and is fixedly sleeved with a bearing, and the outer ring of the bearing is fixedly connected to the inner wall of the annular groove. The top of the fixed rod 3 is fixedly installed with a cross plate 4. Two electric push rods 5 are fixedly installed at the bottom of the cross plate 4. A connecting plate 6 is fixedly installed on the output shafts of the two electric push rods 5. A test plate 7 is fixedly installed at the bottom of the connecting plate 6. When the output shafts of the electric push rods 5 extend downward, the connecting plate 6 moves downward, and the connecting plate 6 moving downward drives the test plate 7 to move downward to contact the circuit board to be detected, thereby detecting the circuit board to be detected by contact. Four fixing plates 8 are fixedly installed on the rotating tube 2. Rectangular frame plates 10 are respectively fixedly installed on one side of the four fixing plates 8. Fixed L-shaped placing plates 18 are respectively fixedly installed on the inner walls of one side of the four rectangular frame plates 10. Moving L-shaped placing plates 14 are respectively arranged in the four rectangular frame plates 10. Slide rods 16 are respectively fixedly installed on the outer walls of one side of the four moving L-shaped placing plates 14, and one ends of the four slide rods 16 respectively extend outside the corresponding rectangular frame plates 10 and are respectively slidably connected to the corresponding rectangular frame plates 10. Compression springs 13 are movably sleeved on the four slide rods 16. In order to improve the service life of the compression springs 13, the four compression springs 13 are all tinned springs, and one ends of the four compression springs 13 are respectively fixedly connected to the corresponding moving L-shaped placing plates 14. Pulling plates 17 are respectively fixedly installed at one ends of the four slide rods 16. The compression springs 13 push the moving L-shaped placing plates 14 to closely contact the circuit board to be detected, thereby stably clamping the circuit board to be detected between the fixed L-shaped placing plates 18 and the moving L-shaped placing plates 14.

[0022] In order to make it more convenient for the circuit board to be detected to enter between the fixed L-shaped placing plate 18 and the moving L-shaped placing plate 14, trapezoidal guiding inclined plates 15 are respectively fixedly installed at the tops of the fixed L-shaped placing plate 18 and the moving L-shaped placing plate 14. Since one side of the trapezoidal guiding inclined plate 15 is an inclined surface, the circuit board to be detected will enter between the fixed L-shaped placing plate 18 and the moving L-shaped placing plate 14 more conveniently.

[0023] In order to keep the moving L-shaped placement plate 14 moving horizontally at all times, so that the circuit boards placed on the fixed L-shaped placement plate 18 and the moving L-shaped placement plate 14 also remain horizontal at all times, thereby ensuring the accuracy of detection, two stabilizing rods 12 are respectively and fixedly installed on the outer wall of one side of the four moving L-shaped placement plates 14. In order to reduce the friction between the stabilizing rod 12 and the rectangular frame plate 10, thereby reducing the wear degree of the stabilizing rod 12 and affecting the service life of the stabilizing rod 12, two through holes are respectively opened on the outer wall of one side of the four rectangular frame plates 10, and linear bearings are respectively and fixedly installed in the eight through holes. The eight stabilizing rods 12 respectively pass through the eight linear bearings and are respectively slidably connected to the inner walls of the eight linear bearings, and the eight stabilizing rods 12 respectively pass through the corresponding rectangular frame plates 10 and are respectively slidably connected to the corresponding rectangular frame plates 10.

[0024] In order to limit the fixed plate 8 and the rectangular frame plate 10, so that the present device is always located directly below the test plate 7 for different rectangular frame plates 10. A limiting groove 11 is opened at the top of the base 1. Limiting rods 9 are respectively and slidably installed on the four fixed plates 8. When one end of the limiting rod 9 is located in the limiting groove 11, the rectangular frame plate 10 is just located directly below the test plate 7, thereby ensuring the accuracy of the detection result.

[0025] The working principle of the integrated circuit test base provided by the present utility model is as follows: In the initial state, the distance between the fixed L-shaped placement plate 18 and the moving L-shaped placement plate 14 is less than the length of the circuit board to be detected, and the compression spring 13 is in a free state. When the present device needs to be used, first place the circuit board to be detected between the fixed L-shaped placement plate 18 and the moving L-shaped placement plate 14. Since the length of the circuit board to be detected is greater than the distance between the fixed L-shaped placement plate 18 and the moving L-shaped placement plate 14, at this moment, the compression spring 13 changes from the free state to the compressed state. The compression spring 13 will push the moving L-shaped placement plate 14 into close contact with the circuit board to be detected, thereby stably clamping the circuit board to be detected between the fixed L-shaped placement plate 18 and the moving L-shaped placement plate 14. When circuit boards are placed in all four rectangular frame plates 10,

[0026] The output shaft of the electric push rod 5 extends downward to drive the connecting plate 6 to move downward. The downward movement of the connecting plate 6 drives the test plate 7 to move downward to contact the circuit board to be detected, thereby detecting the circuit board to be detected.

[0027] While the electric push rod 5 drives the test board 7 to move downward to detect the circuit board to be detected, the tester can place other circuit boards to be detected in other rectangular frame boards 10 to prepare for the next detection. Since the device is provided with four rectangular frame boards 10, four circuit boards can be placed on the device at the same time. However, the device can only detect one circuit board at a time. Therefore, the staff can replace the circuit boards in the other three rectangular frame boards 10 while the device is detecting the circuit board in one of the four rectangular frame boards 10, thus greatly improving the work efficiency.

[0028] Compared with the related technology, the integrated circuit test base provided by the present invention has the following beneficial effects:

[0029] The present invention provides an integrated circuit test base. The compression spring 13 is used to push the movable L-shaped placement plate 14 into close contact with the circuit board to be detected, and the circuit board to be detected is stably clamped between the fixed L-shaped placement plate 18 and the movable L-shaped placement plate 14. The output shaft of the electric push rod 5 extends downward to drive the test board 7 to move downward to detect the circuit board to be detected. While the electric push rod 5 drives the test board 7 to move downward to detect the circuit board to be detected, the tester can place other circuit boards to be detected in other rectangular frame boards 10, enabling the staff to complete the installation and replacement operations of other circuit boards while detecting the circuit board, and preparing for the next detection, thus greatly improving the work efficiency.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
