The general testing technologies include optical testing technology, electrical testing technology, and functional testing technology. It can detect various defects on the internal board, including short circuits, open circuits, component damage, or poor soldering.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the testing process, the inner board of the mobile phone is affected by the mechanical vibration of the testing device itself, airflow disturbance, etc., causing the inner board of the mobile phone to shake and resulting in blurred images; therefore, a mobile phone inner board testing device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the existing technology that the inner board of the mobile phone is affected by the mechanical vibration and airflow disturbance of the detection device itself during the detection process, which causes the inner board of the mobile phone to shake and the image to become blurry. Therefore, this invention proposes a mobile phone inner board detection device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mobile phone inner board detection device, comprising a detection device body, a mobile phone inner board mounted on the surface of the detection device body, two fixed shafts rotatably connected to the surface of the detection device body, a fixed plate fixedly connected to one end of the fixed shaft, a threaded rod inserted into the fixed plate, a stop plate rotatably connected to one end of the threaded rod, and a baffle fixedly connected to the arc surface of the fixed shaft, the surface of the baffle being slidably connected to the mobile phone inner board.
[0006] The aforementioned components achieve the following effect: they clamp and stabilize the inner board of the mobile phone on the main body of the testing device, preventing the inner board from being affected by the mechanical vibration and airflow disturbance of the testing device itself during the testing process, which would cause the inner board to shake and result in blurred images, thus providing a stable testing environment for the inner board of the mobile phone.
[0007] Preferably, a limiting rod is slidably inserted into the fixing plate, and one end of the limiting rod is fixedly connected to the abutment plate.
[0008] The effect achieved by the above components is that by setting the limit rod, the movement trajectory of the stop plate is restricted, preventing the threaded rod from rotating and driving the stop plate to rotate together while it is advancing.
[0009] Preferably, a protective pad is fixedly connected to the surface of the abutment, the protective pad is made of silicone, and the surface of the protective pad is slidably connected to the inner panel of the mobile phone.
[0010] The effect achieved by the above-mentioned components is that by setting up protective pads, the inner board of the phone is protected when it is clamped, preventing direct friction between the inner board and the backing plate, which would otherwise cause wear and tear on the inner board.
[0011] Preferably, a torsion spring is fitted onto the surface of the fixed shaft, and the two ends of the torsion spring are fixedly connected to the baffle and the detection device body, respectively.
[0012] The effect achieved by the above components is that, under the action of the torsion spring, the fixed shaft can be quickly and automatically rotated away, thus avoiding the problem that the detection device body is not easy to place when the inner board of the mobile phone is placed.
[0013] Preferably, two L-shaped plates are fixedly connected to the surface of the detection device body, and a rod is slidably inserted into the two L-shaped plates. One end of the rod is fixedly connected to a pull plate. A limit plate is fixedly connected to the arc surface of the fixed shaft. An insertion hole is opened on the surface of the limit plate, and the rod is slidably connected to the inner wall of the insertion hole of the limit plate.
[0014] The effect achieved by the above components is to fix the fixing shaft at a certain angle after the inner board of the mobile phone is placed, thus avoiding the possible shaking of the inner board of the mobile phone under the torsion force of the torsion spring after clamping.
[0015] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the pull plate and the L-shaped plate, respectively.
[0016] The aforementioned components achieve the following effect: under the action of the spring, the insertion rod is automatically inserted into the hole of the limiting plate without being lost, thus improving the practicality of the device.
[0017] Preferably, a rotating head is fixedly connected to the end of the threaded rod away from the abutment plate, and the rotating head is gear-shaped.
[0018] The effect achieved by the above components is as follows: by setting a rotating head, it is convenient for the operator to rotate the threaded rod. The gear-shaped rotating head can enhance the friction with the operator's palm, making it easier to rotate the threaded rod.
[0019] This invention achieves the effect of clamping and stabilizing the inner board of the mobile phone on the main body of the testing device, avoiding the impact of mechanical vibration and airflow disturbance of the inner board of the mobile phone on the mechanical vibration and airflow disturbance of the testing device itself during the testing process, which would cause the inner board of the mobile phone to shake and result in blurred images, thus providing a stable testing environment for the inner board of the mobile phone.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a mobile phone inner board detection device includes a detection device body 1, on which a mobile phone inner board 2 is mounted. Two fixed shafts 3 are rotatably connected to the surface of the detection device body 1. A fixed plate 4 is fixedly connected to one end of each fixed shaft 3. A threaded rod 5 is threadedly inserted into the fixed plate 4. A stop plate 6 is rotatably connected to one end of the threaded rod 5. A baffle 7 is fixedly connected to the arc surface of the fixed shafts 3. The surface of the baffle 7 is slidably connected to the mobile phone inner board 2, achieving a stable clamping effect on the mobile phone inner board 2 on the detection device body 1. This avoids the mobile phone inner board 2 from being affected by mechanical vibrations or airflow disturbances of the detection device body 1 itself during the detection process, preventing the mobile phone inner board 2 from shaking and causing image distortion. In case of a smear, a stable testing environment is provided for the inner board 2 of the mobile phone. A limiting rod 8 is slidably inserted into the fixing plate 4. One end of the limiting rod 8 is fixedly connected to the abutment plate 6. By setting the limiting rod 8, the movement trajectory of the abutment plate 6 is restricted, preventing the threaded rod 5 from rotating and driving the abutment plate 6 to rotate together. A protective pad 9 is fixedly connected to the surface of the abutment plate 6. The protective pad 9 is made of silicone material and is slidably connected to the surface of the inner board 2 of the mobile phone. By setting the protective pad 9, the inner board 2 of the mobile phone is protected when clamped, preventing direct friction between the inner board 2 of the mobile phone and the abutment plate 6, which would cause wear to the inner board 2 of the mobile phone. The surface of the fixing shaft 3 is sleeved. A torsion spring 10 is provided, with its two ends fixedly connected to the baffle 7 and the detection device body 1, respectively. The force of the torsion spring 10 achieves the effect of quickly and automatically rotating the fixed shaft 3, avoiding the problem of the detection device body 1 being difficult to place when the inner panel of the mobile phone 2 is placed. Two L-shaped plates 11 are fixedly connected to the surface of the detection device body 1, and a rod 12 is slidably inserted into each L-shaped plate 11. One end of the rod 12 is fixedly connected to a pull plate 13. A limiting plate 14 is fixedly connected to the arc surface of the fixed shaft 3, and a hole is provided on the surface of the limiting plate 14. The rod 12 is slidably connected to the inner wall of the hole in the limiting plate 14, achieving the effect of fixing the fixed shaft 3 at a certain angle after the inner panel of the mobile phone 2 is placed. This design avoids potential shaking of the inner panel 2 of the mobile phone after clamping due to the torque force of the torsion spring 10. The arc surface of the insertion rod 12 is fitted with a spring 15, and the two ends of the spring 15 are fixedly connected to the pull plate 13 and the L-shaped plate 11, respectively. Under the action of the spring 15, the insertion rod 12 is automatically inserted into the insertion hole of the limiting plate 14 and the insertion rod 12 is not lost, which improves the practicality of the device. The end of the threaded rod 5 away from the abutment plate 6 is fixedly connected to a rotating head 16. The rotating head 16 is gear-shaped. By setting the rotating head 16, it is possible to facilitate the operator to rotate the threaded rod 5. The gear-shaped rotating head 16 can enhance the friction with the operator's palm, making it easier to rotate the threaded rod 5.
[0026] Working principle: When the operator needs to clamp the inner panel 2 of the mobile phone, they move the fixing shaft 3. The fixing shaft 3 will drive the limiting plate 14, the fixing plate 4, and the baffle 7 to rotate together. At this time, the torsion spring 10 will be in a torsional state, pulling the pull plate 13 upward. The pull plate 13 will drive the insertion rod 12 to move upward. At this time, the spring 15 will be in a stretched state. When the fixing shaft 3 drives the baffle 7 to rotate to the position below the inner panel 2 of the mobile phone and the limiting plate 14 to the position below the L-shaped plate 11, it will stop. The pull plate 13 will be released, and the spring 15 will release the stretched force, driving the insertion rod 12 to insert into the insertion hole of the limiting plate 14, completing the fixation of the fixing shaft 3. Then, the rotating head 16 will rotate. The threaded rod 5 rotates and moves downwards, driving the abutment plate 6 and protective pad 9 downwards together. At this time, the limiting rod 8 moves downwards along with the abutment plate 6 to prevent the abutment plate 6 from rotating along with the threaded rod 5. This continues until the protective pad 9 is in contact with the surface of the inner board 2 of the mobile phone, thus achieving a stable clamping of the inner board 2 of the mobile phone. This achieves the effect of clamping and stabilizing the inner board 2 of the mobile phone on the detection device body 1, avoiding the impact of mechanical vibration and airflow disturbance of the inner board 2 of the mobile phone on the detection device body 1 during the detection process, which would cause the inner board 2 to shake and result in blurred images. This provides a stable detection environment for the inner board 2 of the mobile phone.
