Description

Technical Field

[0001] This utility model relates to the field of whole machine FCT testing technology, and in particular to a whole machine FCT testing fixture. Background Technology

[0002] As the integration and complexity of electronic devices increase, traditional modular testing struggles to detect assembly defects, manual testing is inefficient, and it's difficult to simulate real-world scenarios to cover complex functions, leading to missed detections. Furthermore, high rework and after-sales costs, coupled with stricter industry standards, spurred the invention of whole-device FCT (Full-Scale Testing).

[0003] Before production, workers clean the tooling and templates and check the adjustment components. Then, the entire machine is placed on the workbench and fixed with a fixing device to prevent displacement during testing. The machine to be tested is then connected to the test circuit to quickly test whether the various functions of the product are normal and to determine whether there are problems such as circuit faults, poor soldering of components, or program errors. However, when switching to products of different thicknesses on the production line, the entire clamping assembly needs to be replaced. The replacement process requires the disassembly of multiple parts, causing the test line to stop and wait, reducing production efficiency and making it difficult to meet the production needs of multiple machine types. Therefore, in order to solve this problem, we have proposed a whole-machine FCT test tooling. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a whole-machine FCT testing fixture that can achieve precise adjustment of the clamping height. Whether it is a thinner small whole machine or a thicker whole machine, the appropriate clamping height can be found by fine adjustment of the nut, avoiding the problem of clamping looseness or excessive compression caused by height mismatch. The elasticity of the third spring can enhance the fit with the whole machine, and the softness of the rubber plate can avoid scratches or indentations on the surface of the whole machine during the test, effectively protecting the appearance of the whole machine and reducing the wear rate of the whole machine during the test.

[0005] This utility model also provides a complete FCT testing fixture, including a machine body, a rotary cylinder inside the machine body, a rotary plate at the output end of the rotary cylinder, two arc-shaped fixing plates fixedly installed on the top of the machine body, an arc-shaped clamping plate above the arc-shaped fixing plates, a first support plate fixedly installed on one side of the arc-shaped fixing plates, a second support plate fixedly installed on one side of the arc-shaped clamping plate, a first spring fixedly installed below the second support plate, an adjusting rod fixedly installed below the second support plate, and lifting motors fixedly installed on both sides of the top of the machine body, with a third support plate fixedly installed on the output shaft of the lifting motor.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5 This utility model provides a whole-machine FCT testing fixture, which includes a machine body 1. The machine body 1 facilitates testing of the whole machine. A rotary cylinder 2 is installed inside the machine body 1, which drives a rotary plate 3 to rotate. The output end of the rotary cylinder 2 is provided with the rotary plate 3, which facilitates rotation testing. Two arc-shaped fixing plates 4 are fixedly installed on the top of the machine body 1. An arc-shaped clamping plate 5 is provided above the arc-shaped fixing plates 4, which facilitates control of the whole machine. A first support plate 6 is fixedly installed on one side of the arc-shaped fixing plates 4. A second support plate 7 is fixedly installed on one side of the plate 5. A first spring 8 is fixedly installed below the second support plate 7. The elasticity of the first spring 8 can provide cushioning. An adjusting rod 9 is fixedly installed below the second support plate 7. The adjusting rod 9 can be used to control the lifting and lowering of the arc-shaped clamping plate 5. Lifting motors 10 are fixedly installed on both sides of the upper part of the machine body 1. The lifting motors 10 can drive the third support plate 11 to lift and lower, which can facilitate the fixing of the whole machine. The output shaft of the lifting motor 10 is fixedly installed on the third support plate 11, which can facilitate the fixing of the whole machine.

[0026] Specifically, one end of the adjusting rod 9 extends to the external thread of the first support plate 6 and is connected to a nut 12. The upper surface of the nut 12 is in close contact with the lower surface of the first support plate 6. When the upper surface of the nut 12 is in close contact with the lower surface of the first support plate 6, it is convenient to control the movement of the adjusting rod 9.

[0027] Specifically, the arc-shaped clamp 5 has two sliding grooves inside, and each sliding groove of the arc-shaped clamp 5 is provided with a sliding plate 26. A second spring 13 is fixedly installed at one end of each sliding plate 26, and an auxiliary clamp 27 is fixedly installed at one end of the second spring 13. The auxiliary clamp 27 can facilitate the fixation of the whole machine.

[0028] Specifically, one end of the first spring 8 is fixedly connected to the first support plate 6, and an auxiliary rod 14 is fixedly installed at the lower end of the arc-shaped clamping plate 5. One end of the auxiliary rod 14 extends into the interior of the arc-shaped fixing plate 4. When one end of the auxiliary rod 14 extends into the interior of the arc-shaped fixing plate 4, the arc-shaped clamping plate 5 can be easily adjusted.

[0029] Specifically, a movable plate 15 is provided at one end of the third support plate 11. A circular hole is opened inside the third support plate 11. A first guide rod 16 is fixedly installed at one end of the movable plate 15. The first guide rod 16 extends into the circular hole opened in the third support plate 11. By extending the first guide rod 16 into the circular hole opened in the third support plate 11, the movable plate 15 can move smoothly and prevent the movable plate 15 from deviating.

[0030] Specifically, a first positioning plate 17 is fixedly installed above the third support plate 11, and a second positioning plate 18 is fixedly installed above the movable plate 15. A bolt 19 is provided inside the second positioning plate 18, and one end of the bolt 19 extends into the interior of the first positioning plate 17. The extension of the bolt 19 into the interior of the first positioning plate 17 facilitates the adjustment of the movable plate 15 for movement.

[0031] Specifically, the movable plate 15 has an internal mounting groove 20, and a third spring 21 is fixedly installed inside the mounting groove 20. A rubber plate 22 is fixedly installed at one end of the third spring 21. The whole machine can be fixed by the rubber plate 22 to prevent scratches or indentations.

[0032] Specifically, a first limiting plate 23 is fixedly installed inside the mounting groove 20, a second limiting plate 24 is fixedly installed above the rubber plate 22, and a plurality of second guide rods 25 are fixedly installed above the rubber plate 22. The second guide rods 25 extend into the interior of the moving plate 15. When the second guide rods 25 extend into the interior of the moving plate 15, the rubber plate 22 can move smoothly and prevent the rubber plate 22 from deviating during the movement.

[0033] Working principle: First, place the machine to be tested above the rotating plate 3. Adjust the height according to the height of the machine. During adjustment, rotate the adjusting rod 9 to the nut 12 extending to the outside of the first support plate 6. Since one end of the adjusting rod 9 is fixedly connected to the second support plate 7, and the second support plate 7 is fixed to the arc-shaped clamping plate 5, rotating the nut 12 can change the length of the adjusting rod 9 extending out of the first support plate 6, thereby driving the second support plate 7 and the arc-shaped clamping plate 5 to move up and down. At the same time, the auxiliary rod 14 at the lower end of the arc-shaped clamping plate 5 extends into the arc-shaped fixed plate 4, which can play a guiding role during the movement of the arc-shaped clamping plate 5 to prevent it from deviating. One end of a spring 8 is fixedly connected to the first support plate 6, and the other end is fixed to the second support plate 7. This provides cushioning during adjustment, ensuring the smooth movement of the arc-shaped clamping plate 5. Ultimately, the arc-shaped clamping plate 5 is adjusted to a height suitable for the overall machine thickness, preventing loose clamping or excessive compression. After the arc-shaped clamping plate 5 is adjusted to its correct position, the sliding plate 26 in its internal groove and the second spring 13, together with the auxiliary clamping plate 27, further secure the entire machine. When the auxiliary clamping plate 27 contacts the entire machine, the compression of the auxiliary clamping plate 27 by the machine pushes the second spring 13 to compress. The elastic force of the second spring 13 reacts to the auxiliary clamping plate 27, causing the auxiliary clamping plate 27 to... 7. The third support plate 11 is tightly fitted to the surface of the machine. Upon starting the lifting motor 10, its output shaft drives the third support plate 11 to move up and down, adjusting it to a height suitable for the machine. Then, the moving plate 15 is moved using bolts 19. Simultaneously, the moving plate 15 slides within the circular hole of the third support plate 11 via the first guide rod 16, achieving horizontal position adjustment. After the moving plate 15 is adjusted, the rubber plate 22 in the mounting groove 20 contacts the surface of the machine. Since a third spring 21 is fixed above the rubber plate 22, the spring force of the third spring 21 pushes the rubber plate 22 to tightly fit against the surface of the machine. To enhance the stability of the test docking, the softness of the rubber plate 22 can prevent scratches or indentations on the surface of the whole machine during the test. The first limiting plate 23 in the mounting groove 20 cooperates with the second limiting plate 24 above the rubber plate 22 to prevent the rubber plate 22 from moving excessively and causing damage to the third spring 21. The second guide rod 25 extends into the interior of the moving plate 15 and can play a guiding role during the movement of the rubber plate 22 to ensure its stable movement direction. Finally, the rotating plate 3 is driven to rotate by the rotating cylinder 2, which can drive the whole machine to rotate, meet different test requirements, and complete the entire process of the whole machine FCT test.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
