Description

Technical Field

[0001] This utility model relates to the field of FCT testing equipment technology, specifically to a semi-automatic FCT testing mechanism. Background Technology

[0002] FCT, or Functional Circuit Testing, is a crucial step in electronic manufacturing to verify the functional integrity of products. Its core is to simulate actual working conditions to test whether the various functions of a circuit board or the entire machine meet the design specifications, ensuring that the product meets performance standards before leaving the factory.

[0003] Semi-automatic FCT testing equipment requires manual placement of the circuit board to be tested. If the circuit board is not placed accurately, it will not only directly affect the accuracy of the circuit board test results, but the pressing mechanism will also deform and damage the circuit board, thus affecting the test results and causing deformation and damage to the circuit board.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Example 1 Please see Figures 1-5 This utility model provides a technical solution: A semi-automatic FCT testing mechanism includes a base 1. A limiting mechanism is provided on the surface of the top of the base 1. The limiting mechanism includes a fixed seat 3 at the top of the base 1. A drive motor 14 is fixedly installed inside the fixed seat 3. A drive plate 13 is fixedly installed at the output end of the top of the drive motor 14. Two connecting rods 12 are rotatably installed at the bottom end of the drive plate 13. Two base plates 11 are slidably installed inside the fixed seat 3. Wedge-shaped clamping plates 8 are fixedly connected to the top of each of the two base plates 11. A limiting block 9 is slidably installed at the top of the wedge-shaped clamping plate 8. An elastic element 10 is provided between the bottom end of the limiting block 9 and the wedge-shaped clamping plate 8. Through the cooperation of the drive motor 14, connecting rods 12, base plates 11 and other components, the wedge-shaped clamping plate 8 can be precisely driven to move, limiting the circuit board and ensuring that the circuit board is accurately positioned during testing, thus improving the accuracy of the test results. At the same time, it avoids damage to the circuit board caused by positional deviation due to the pressing mechanism. The limiting block 9 and the elastic element 10 at the top can buffer the descending pressing mechanism, further preventing damage to the circuit board and ensuring the accuracy of the circuit board test results.

[0020] The ends of the two connecting rods 12 away from the drive plate 13 are rotatably mounted on the bottom ends of the two base plates 11. The two connecting rods 12 can stably drive the two base plates 11 to slide in opposite directions, ensuring that the two wedge-shaped clamps 8 can clamp the circuit board synchronously and stably.

[0021] The top surface of the fixed base 3 is provided with a limiting groove 6, and the inside of the limiting groove 6 is provided with four sliding grooves 7. The setting of the limiting groove 6 and the sliding grooves 7 provides space and accurate guidance for the placement and limiting of the circuit board, further improving the accuracy and stability of the limiting mechanism.

[0022] The wedge-shaped clamp 8 is located inside the limiting groove 6 and slides with it through the sliding groove 7. The sliding groove 7 can restrict and guide the movement of the wedge-shaped clamp 8, thereby ensuring that the wedge-shaped clamp 8 can stably clamp the circuit board.

[0023] Two spring tubes 15 are provided between the two base plates 11. The spring tubes 15 can play the role of elastic buffer, and at the same time, they can adjust and maintain the clamping force in the entire limiting mechanism, and provide appropriate pressure distribution and buffering for the base plates 11, so as to avoid the wedge clamps 8 from scratching, squeezing and other damage to the circuit board when limiting.

[0024] In use, first place the circuit board to be tested in the limiting groove 6 on the surface of the fixed base 3, then start the drive motor 14 to drive the drive plate 13 at the output end to rotate. While the drive plate 13 is rotating, it will push the two base plates 11 to slide in the fixed base 3 through the connecting rod 12, thereby driving the wedge clamp 8 to move in the slide groove 7. When the two wedge clamps 8 come close to each other, they will limit and fix the circuit board. Then start the hydraulic cylinder 2, which will drive the pressure plate 5 to move down and cooperate with the jig 4 to stably press the circuit board while performing the FCT test. After the test is completed, the hydraulic cylinder 2 will drive the pressure plate 5 to move up, the drive motor 14 will reverse, release the limit of the circuit board, and finally take it out to complete the work.

[0025] Example 2 Please see Figures 1-5 This utility model provides a technical solution: A hydraulic cylinder 2 is installed at the top of the base 1, and a pressure plate 5 is fixedly installed at the bottom of the hydraulic cylinder 2. Through the cooperation of the hydraulic cylinder 2 and the pressure plate 5, a stable and sufficient pressure can be provided to ensure that the circuit board has good contact with the fixture 4 during the test, thereby improving the accuracy and reliability of the test results.

[0026] The top of the fixed base 3 is equipped with a fixture 4. The pressure plate 5 cooperates with the fixture 4 through the hydraulic cylinder 2. When the pressure plate 5 cooperates with the fixture 4 under the drive of the hydraulic cylinder 2, it provides a stable testing environment for the circuit board, ensuring that the circuit board will not move during the test and guaranteeing the accuracy of the test results.

[0027] Unlike Example 1, the hydraulic cylinder 2 and the pressure plate 5 work together to provide stable and sufficient pressure, ensuring good contact between the circuit board and the fixture 4 during the test. This provides a stable testing environment for the circuit board, ensuring that the circuit board will not move during the test and improving the accuracy and reliability of the test results.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
