Two I-shaped guide blocks 33 are arranged in the first square groove 32. The I-shaped guide blocks 33 are fixedly connected to the base plate 1. The I-shaped guide blocks 33 are used to guide the movable parts of the positioning mechanism 3 during centering positioning to prevent the positioning mechanism 3 from deviating during positioning and causing inaccurate positioning, thereby affecting the detection accuracy.

[0067] Furthermore, if Figure 6 As shown, the I-shaped guide block 33 is provided with a guide hole 331 and a guide groove 332 , wherein the guide holes 331 are distributed on both sides of the I-shaped guide block 33 , and the guide groove 332 is distributed in the middle inner position of the I-shaped guide block 33 , and a wedge block 34 is provided in the guide groove 332 .

[0068] Furthermore, if Figure 7 As shown, guide pin mounting grooves 341 are provided at both ends of the wedge block 34, and the guide pin mounting grooves 341 are used to install guide pins. Inclined surfaces 342 are provided in the middle positions on both sides of the wedge block 34, and push blocks 35 are fitted on the inclined surfaces 342 on both sides of the wedge block 34. The push blocks 35 are used to push the tested mobile phone case to both sides to achieve positioning.

[0069] A first spring 351 is disposed at one end of the push block 35 , and the first spring 351 is used to push the push block 35 after detection, so as to reset the push block 35 .

[0070] A spring mounting pin 352 is disposed at one end of the first spring 351 . The spring mounting pin 352 is used to fix the position of the first spring 351 . The spring mounting pin 352 vertically passes through the push block 35 and is fixedly connected to the push block 35 .

[0071] Positioning principle: When the wedge block 34 is forced to move forward, the inclined surface 342 of the wedge block 34 is used to change the direction of the force, pushing the push block 35 attached to the inclined surface 342 to move to both sides, thereby pressing the inner cavity of the mobile phone case to be tested to achieve positioning.

[0072] Furthermore, if Figure 8As shown, the base plate 1 is provided with a second square groove 11, a connecting rod 36 is provided in the second square groove 11, a handle 37 is provided at one end of the connecting rod 36, the second square groove 11 is located directly below the first square groove 32, the connecting rod 36 passes through the second square groove 11 and is slidably connected to the base plate 1, and the handle 37 is rotatably connected to the connecting rod 36.

[0073] Furthermore, if Fig. 9 As shown, the surface of the connecting rod 36 is provided with a first stopper 38 and a second stopper 39 at positions corresponding to the two ends of the I-shaped guide block 33 . The first stopper 38 and the second stopper 39 are inserted into the surface of the connecting rod 36 and fixedly connected to the connecting rod 36 .

[0074] Furthermore, if Fig.10 As shown, a first guide pin 381 is provided on the side surface of the first stopper 38, and the first guide pin 381 is slidably connected to the guide hole 331 on one side of the I-shaped guide block 33, and a second spring 382 is adapted between the first guide pin 381 and the guide pin mounting groove 341 at one end of the wedge block 34.

[0075] A second guide pin 391 is disposed on the side surface of the second stopper 39 . The second guide pin 391 passes through the guide hole 331 on the other side of the I-shaped guide block 33 and is fixedly connected to the guide pin mounting groove 341 on the other end of the wedge block 34 .

[0076] Centering positioning principle:

[0077] During testing, the handle 37 is rotated counterclockwise to drive the connecting rod 36 to move forward, and then the first stopper 38 on the connecting rod 36 is driven to move forward. Since the movement of the first stopper 38 will squeeze the second spring 382 on the first guide pin 381 and compress it forward, the wedge block 34 in the I-shaped guide block 33 is moved forward by the elastic force of the second spring 382. As the wedge block 34 moves forward, an extrusion force is applied to the push block 35 attached to the inclined surface of the wedge block 34, so that the push block 35 moves to both sides and presses the inner cavity of the mobile phone case under test, thereby realizing center positioning, so that the test mechanisms at both ends of the positioning mechanism can detect the position of the side holes of the mobile phone under test.

[0078] After the detection is completed, the handle 37 is turned clockwise, and the first stopper 38 returns to the initial position due to the elastic force of the second spring. The first stopper 38 drives the connecting rod 36 back to the initial position, and then the second guide pin 391 drives the wedge block 34 back to the initial position, and the push block 35 returns to the initial position due to the elastic force of the first spring. At this time, the mobile phone case to be tested can be removed.

[0079] Detection method:

[0080] Place the mobile phone case to be tested on the fixed plate of the positioning mechanism with the back of the mobile phone case facing upwards, pre-tighten the mobile phone case with the clamping mechanism, turn the handle counterclockwise to completely position the mobile phone case. After positioning, further use the clamping mechanism to completely tighten the mobile phone case, and press each test pin on the testing mechanism respectively. If the test pin can be smoothly inserted into the side hole of the mobile phone case, the side hole position of the mobile phone case is qualified, otherwise the processing is unqualified. After the inspection is completed, turn the handle clockwise and release the clamping mechanism to remove the mobile phone case to be tested.

[0086] Specifically, the step S100 includes the following steps:

[0087] Step S101, rotating the handle on the positioning mechanism, driving the wedge block inside the I-shaped guide block to move forward through the connecting rod connected to the handle;

[0088] Step S102, when the wedge-shaped block moves forward, the push blocks on both sides of the wedge-shaped block are pushed to move outward;

[0089] Step S103, when the push block moves outward, it squeezes the inner wall of the mobile phone case to be tested, and pushes the mobile phone case to be tested to achieve center positioning; the details are as described above.

[0090] Specifically, step S300 includes the following steps:

[0091] Step S301, inserting each test pin on the test mechanism into the corresponding side hole of the tested mobile phone case;

[0092] Step S302, observing and determining whether all the test pins can be fully inserted into the side holes corresponding to the tested mobile phone case;

[0093] Step S303, when all the test pins on the test mechanism can be fully inserted into the side holes corresponding to the tested mobile phone case, it is determined that the side hole position processing of the tested mobile phone case is qualified; the details are as described above.

[0094] In summary, the present invention has the following beneficial effects: the present invention adopts a positioning mechanism to position the mobile phone case to be inspected, thereby realizing the automatic adjustment of the positioning in a simple structure, and adopts the testing mechanisms at both ends of the positioning mechanism to inspect the mobile phone case to be inspected, so that the inspector can complete the inspection of the side holes of the mobile phone case by pressing the test pins at both ends of the testing mechanism, thereby simplifying the structure of the inspection device, reducing the inspection cost, and improving the inspection accuracy and efficiency.
