[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a backlight bonding fixture for preventing light leakage from mobile phone screens, including a base 1, a positioning component 2 installed on the surface of the base 1, a pressing plate 3 installed on the arc surface of the positioning component 2, and an adjustment device 4 provided on the surface of the pressing plate 3, which achieves the effect of accurately adjusting the pressing plate 3, avoiding the situation where the light strip and back panel are not properly bonded due to the difficulty in controlling the degree of pressing, thus causing light leakage, and improving the practicality of the device. An auxiliary device 5 is provided on the surface of the base 1, which achieves the effect of anti-slip for the processed parts, preventing the processed parts from shaking and detaching from the base 1 during pressing, thus causing light leakage, and improving the practicality of the device.

[0024] The specific settings and functions of its adjustment device 4 and auxiliary device 5 will be explained in detail below.

[0025] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjusting device 4 includes a connecting block 401, which is fixedly connected to the surface of the pressing plate 3 and slidably connected to the arc surface of the positioning component 2. A support rod 402 is fixedly connected to the surface of the connecting block 401, and a push plate 404 is slidably connected to the arc surface of the support rod 402. A limiting rod 405 is slidably inserted into the push plate 404, and a circular plate 407 is fixedly connected to one end of the limiting rod 405. A plurality of limiting holes 408 are opened on the arc surface of the positioning component 2, and a spring 406 is sleeved on the arc surface of the limiting rod 405. The two ends of the spring 406 are respectively connected to the circular plate 407 and the push plate 408. 4. Release the circular plate 407. The rebound force of the spring 406 drives the circular plate 407, which in turn drives the limiting rod 405 to slide within the push plate 404 until the limiting rod 405 is inserted into the limiting hole 408. This achieves a stable connection of the limiting rod 405, preventing shaking during pressing and thus avoiding any wobbling in the limiting rod 405's position on the positioning component 2. This improves the stability of the device. The arc surface of the support rod 402 is rotatably connected to a rotating ring 403. The surface of the rotating ring 403 is fixedly connected to the push plate 404. The surface of the connecting block 401 has a recycling groove 409. By moving the limiting rod 405... Pull the 05 rod out from the limiting hole 408, then rotate the rotating ring 403. The rotating ring 403 drives the push plate 404 to rotate on the arc surface of the support rod 402. The push plate 404 drives the limiting rod 405, and the limiting rod 405 drives the circular plate 407 until the limiting rod 405 is perpendicular to the recycling groove 409. Then push the circular plate 407, and the circular plate 407 drives the limiting rod 405 to slide within the push plate 404. The limiting rod 405 drives the circular plate 407 until the limiting rod 405 is inserted into the recycling groove 409, achieving the effect of rotating and recycling the limiting rod 405. This avoids the shaking caused during adjustment, which could cause the limiting rod 405 to be stuck in the push plate. The sliding within 404 results in a situation where the operator needs to continuously pull the limiting rod 405. A positioning plate 410 is fixedly connected to the surface of the connecting block 401. The size of the limiting rod 405 matches the size of the limiting hole 408. Rotating the rotating ring 403 causes the pushing plate 404 to rotate on the arc surface of the support rod 402. The pushing plate 404 drives the limiting rod 405, which in turn drives the circular plate 407 until the limiting rod 405 touches the positioning plate 410. This achieves the effect of quickly positioning the limiting rod 405, allowing the operator to quickly adjust the pressing and thus speeding up the process.

[0026] Reference Figure 4 and Figure 5As shown, specifically, the auxiliary device 5 includes an anti-slip pad 51, which is slidably connected to the surface of the base 1. Short rods 52 are fixedly connected to both sides of the base 1. A strip plate 54 is rotatably connected to the arc surface of the short rods 52. A fixing rod 55 is slidably inserted into the strip plate 54. A fixing hole 57 is opened on the surface of the anti-slip pad 51. A baffle 56 is fixedly connected to the arc surface of the fixing rod 55. The size of the fixing rod 55 is adapted to the size of the fixing hole 57. Pulling the fixing rod 55 to slide within the strip plate 54 causes the fixing rod 55 to drive the baffle 56 until the baffle 56 touches the strip plate 54, thus achieving the effect of blocking the fixing rod 55. This design avoids the shaking during disassembly, which could cause the fixing rod 55 to slip off the strip plate 54 and be damaged. A torsion spring 53 is fitted on the arc surface of the short rod 52. The two ends of the torsion spring 53 are fixedly connected to the strip plate 54 and the base 1, respectively. After the anti-slip pad 51 is released, the torque of the torsion spring 53 drives the strip plate 54 to rotate on the arc surface of the short rod 52. The strip plate 54 drives the fixing rod 55 until the fixing rod 55 is reset, thus achieving the effect of automatic reset of the fixing rod 55. This reduces the number of steps for operators, increases their work efficiency, and improves the convenience of the device.

[0027] Working principle: When adjustment of the pressing plate 3 is required, the limiting rod 405 is pulled out from the limiting hole 408, and then the rotating ring 403 is rotated. The rotating ring 403 drives the pushing plate 404 to rotate on the arc surface of the support rod 402. The pushing plate 404 drives the limiting rod 405, and the limiting rod 405 drives the circular plate 407 until the limiting rod 405 touches the positioning plate 410. Then the circular plate 407 is pushed, and the circular plate 407 drives the limiting rod 405 to slide within the pushing plate 404. The limiting rod 405 drives the circular plate 407 until the limiting rod 405 is inserted into the recycling groove 409. Then the connecting block 401 is pulled to drive the pressing plate 3 to slide and adjust on the arc surface of the positioning component 2. After the adjustment is completed, the limiting rod 405 is then pulled back. Pull it out from the recycling tank 409, then rotate the rotating ring 403. The rotating ring 403 drives the push plate 404 to rotate on the arc surface of the support rod 402. The push plate 404 drives the limiting rod 405, and the limiting rod 405 drives the circular plate 407 until the limiting rod 405 is perpendicular to the limiting hole 408. Release the circular plate 407. The rebound force of the spring 406 drives the circular plate 407. The circular plate 407 drives the limiting rod 405 to slide in the push plate 404 until the limiting rod 405 is inserted into the limiting hole 408. This achieves the effect of accurately adjusting the pressing plate 3, avoiding the situation where the light strip and back plate and other components are not properly attached due to the difficulty in controlling the degree of pressing, thus causing light leakage. This improves the practicality of the device.

[0028] When the anti-slip pad 51 needs to be replaced, the fixing rod 55 is pulled and slid within the strip plate 54. The fixing rod 55 drives the baffle 56 until the baffle 56 touches the strip plate 54, releasing the fixation of the anti-slip pad 51. The torque of the torsion spring 53 drives the strip plate 54 to rotate on the arc surface of the short rod 52. The strip plate 54 drives the fixing rod 55 until the fixing rod 55 returns to its original position. After the anti-slip pad 51 is placed on the base 1, the strip plate 54 is rotated to drive the fixing rod 55 to rotate on the arc surface of the short rod 52 until the fixing rod 55 is perpendicular to the fixing hole 57. Then, the fixing rod 55 is pushed to slide within the strip plate 54 until the fixing rod 55 is inserted into the fixing hole 57. This achieves the effect of anti-slip on the workpiece, preventing the workpiece from shaking and detaching from the base 1 during pressing, thus avoiding light leakage from the workpiece and improving the practicality of the device.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
