[0026] Example:

[0027] In this embodiment, a smartphone mold testing fixture is provided, comprising: a base 10 having a connecting part and a testing part, and a plurality of sliding grooves 11 formed on the base 10; a mounting plate 20 detachably mounted on the base 10, and a plurality of positioning holes 21 formed on the mounting plate 20; positioning blocks 22 mounted on the positioning holes 21, and the plurality of positioning blocks 22 surrounding a plurality of accommodating spaces 23; a sliding connecting module, wherein the mounting plate 20 has positioning grooves 24 corresponding one-to-one with the sliding grooves 11, and the sliding connecting module slides into the positioning grooves 24 along the extension direction of the sliding grooves 11, and the connecting part is mounted on the sliding connecting module; and an auxiliary module mounted on the base 10.

[0028] In this embodiment, the base 10 is forged from high-strength aluminum alloy and is rectangular in shape. Its top surface is divided into a connecting part and a testing part by a dividing strip. The connecting part is located on one side of the base 10 and has a row of metal terminals embedded on its surface for stable connection of data lines and power lines of external testing equipment. The testing part is located on the other side of the base 10 and its surface is precision milled to form a flat mounting plane. A retaining edge is provided at the edge of the plane to prevent the mounting plate 20 from accidentally slipping off during testing. The mounting plate 20 is a rectangular plate injection molded from ABS engineering plastic. Its dimensions are adapted to the testing section of the base 10. A positioning boss is provided at the bottom, and a corresponding positioning recess is provided at the testing section of the base 10. When the mounting plate 20 is placed on the base 10, the positioning boss engages with the positioning recess to achieve initial positioning. It is then further secured by quick-locking knobs evenly distributed along the edge of the mounting plate 20. A threaded rod is connected to the bottom of the knob and passes through the mounting plate 20. A threaded hole is provided at the corresponding position on the base 10. Tightening the knobs firmly fixes the mounting plate 20 to the base 10, and loosening the knobs allows for easy removal of the mounting plate 20. Multiple positioning holes 21 are distributed in a matrix on the top surface of the mounting plate 20; these positioning holes 21 are through holes. The positioning block 22 is a block structure made of nylon material. The bottom is integrally formed with a cylindrical insert. The outer wall of the insert has a ring of anti-slip texture. When the insert is inserted into the positioning hole 21, the anti-slip texture fits tightly with the inner wall of the positioning hole 21, which can effectively prevent the positioning block 22 from loosening. The accommodating space 23 formed by multiple positioning blocks 22 is rectangular, which can just accommodate the mobile phone and prevent it from shaking. A silicone pad is attached to the side of the positioning block 22 facing the accommodating space 23, which can not only buffer the impact when the mobile phone is put in, but also prevent scratches on the mobile phone shell. Multiple grooves 11 are formed along the length of the edge of the testing section of the base 10. Each groove 11 is a long, convex groove with polished walls and coated with a solid lubricant to reduce friction during sliding. A positioning groove 24 is formed on the edge of the mounting plate 20 corresponding to each groove 11. The positioning groove 24 is a short groove with the same cross-section as the groove 11. When the mounting plate 20 is fixed to the base 10, one end of the positioning groove 24 aligns with one end of the groove 11, forming a continuous channel. The sliding connection module can slide freely along the length of the groove 11. When it slides to the positioning groove 24, the end of the sliding connection module is fully embedded in the positioning groove 24. At this time, the sidewall of the positioning groove 24 restricts the horizontal displacement of the sliding connection module, ensuring precise alignment with the mobile phone in the receiving space 23. The wiring terminals of the connection section are connected to the interface of the sliding connection module via internal wires and move synchronously with the sliding connection module to establish a connection with the mobile phone at different positions.The auxiliary module is mounted on the side of the base 10 test section away from the connection section via an L-shaped metal bracket. The bottom of the bracket is fixed to the base 10 with screws. The height can be finely adjusted by adjusting the elongated hole on the bracket to ensure that it does not affect the loading and unloading of the mounting plate 20 and the movement of the sliding connection module.

[0029] Furthermore, the auxiliary module includes: a first refracting mirror 41, an inspection slot 42 is provided on the receiving space 23, the first refracting mirror 41 is mounted on the base 10 and is located directly below the inspection slot 42; a riser 43 is mounted on the base 10; and a second refracting mirror 44 is mounted on the riser 43, through which the mobile phone structure in the inspection slot 42 is refracted into the second refracting mirror 44.

[0030] In this embodiment, each receiving space 23 has a viewing slot 42 on the side wall away from the sliding connection module. The viewing slot 42 is an elongated hole extending along the length of the receiving space 23, and its height is aligned with the area of ​​the rear camera module of the mobile phone. The first refractor 41 is a square planar reflector with an anti-reflection coating to improve reflectivity. It is mounted inside the base 10 via an adjustable metal bracket. The bottom of the bracket is fixed to the bottom plate of the base 10, and the upper part of the bracket has a rotatable shaft. The first refractor 41 is connected to the bracket via the shaft and can rotate around the shaft to adjust the angle. Finally, it is adjusted so that the mirror surface forms a 45° angle with the horizontal plane, and the center of the mirror surface is on the same vertical line as the center of the viewing slot 42, ensuring that the mobile phone structure, flash light source, and camera module exposed in the viewing slot 42 can be completely reflected onto the mounting plate 20. The riser 43 is a frame structure welded from stainless steel. The bottom is fixed to the edge of the base 10 by expansion screws, and the top has a horizontal platform with an elongated hole for adjusting the position of the second refractor 44. The second refractive mirror 44 is identical in specifications to the first refractive mirror 41. It is also mounted on the platform at the top of the riser 43 via a rotatable bracket, adjusted so that its surface forms a 45° angle with the horizontal plane and is parallel to the surface of the first refractive mirror 41. When the phone to be tested is placed in the receiving space 23, the structure to be inspected is exposed through the inspection slot 42. Light shines onto this structure and is reflected back to the first refractive mirror 41. The first refractive mirror 41 reflects the light to the second refractive mirror 44, which then reflects the light into the eyes of the tester. The tester, standing in front of the mounting plate 20, can directly observe the structural details of the back of the phone to be inspected as seen in the second refractive mirror 44.

[0031] Furthermore, the sliding connection module includes: a sliding seat 31, which is slidably disposed in the sliding groove 11, and a fixing hole 32 is provided on the sliding seat 31; a plug socket 33, which is installed on the sliding seat 31 through the fixing hole 32; and an adapter plug 34, which is detachably installed on the plug socket 33.

[0032] In this embodiment, the sliding seat 31 is a block structure made of brass, and its shape is adapted to the cross-section of the slide groove 11. The bottom has a protrusion that matches the "convex" structure of the slide groove 11, preventing the sliding seat 31 from falling out of the slide groove 11. The width of the sliding seat 31 is slightly smaller than the width of the slide groove 11 to ensure smooth sliding without wobbling. A fixing hole 32 is provided at the center of the top surface of the sliding seat 31. The fixing hole 32 is a circular hole with internal threads. The plug and socket 33 is a rectangular standard interface component. Its bottom has an externally threaded post that matches the fixing hole 32. After screwing the threaded post into the fixing hole 32 and tightening it, the plug and socket 33 can be firmly installed on the sliding seat 31. A rubber gasket is also placed between the two to enhance sealing and shock absorption. The adapter plug 34 is a pluggable interface that matches the plug socket 33. One end of the adapter plug 34 has pins corresponding to the plug socket 33, and the other end is set with different specifications of connectors according to the interface type of the mobile phone to be tested. The connection part between the adapter plug 34 and the plug socket 33 is equipped with a foolproof structure, which can only be inserted in the correct direction to avoid damage to the interface by misinsertion. When different models of mobile phones need to be tested, simply hold the outer shell of the adapter plug 34 and gently pull it out, and then insert the corresponding specification adapter plug 34. The whole process does not require tools and is easy to operate.

[0033] Furthermore, the mounting plate 20 has an auxiliary hole 25 located between two adjacent receiving spaces 23, through which the tested mobile phone is disassembled.

[0034] In this embodiment, the auxiliary holes 25 on the mounting plate 20 are circular through holes. Each auxiliary hole 25 is located at the center of the gap between two adjacent receiving spaces 23. The edges of the holes are chamfered to avoid scratching fingers. The auxiliary holes 25 penetrate the mounting plate 20, and there is a certain gap between their bottom and the test part of the base 10 to allow fingers to be inserted. After the test is completed, since the phone is slightly clamped by the positioning block 22 and the silicone pad, it may require a lot of force to remove it directly by hand and it is easy to slip. At this time, the tester can insert their index finger into the auxiliary hole 25, gently push upwards against the middle of the bottom of the phone, and at the same time use the thumb and index finger of the other hand to pinch the top edge of the phone to easily remove the phone from the receiving space 23. The whole process is smooth and does not easily damage the phone.

[0035] Furthermore, the auxiliary module also includes: a first position sensor 45, mounted on the base 10, for detecting the position information of the mounting plate 20; and a second position sensor 46, on which a detection hole 47 is provided, mounted on the base 10, and the second position sensor 46 detects the mobile phone installation position information in the corresponding accommodating space 23 through the detection hole 47.

[0036] In this embodiment, the first position sensor 45 is a diffuse reflection infrared sensor. Its housing is fixed to the bracket on the edge of the test section of the base 10 with screws. The sensing head faces the side of the mounting plate 20. When the mounting plate 20 is correctly installed on the base 10, the side of the mounting plate 20 will reflect the infrared light emitted by the first position sensor 45. After receiving the reflected light, the sensor outputs a high-level signal, indicating that the mounting plate 20 is in the correct position. If the mounting plate 20 is not installed or its position is off, the side of the mounting plate 20 cannot reflect infrared light, and the sensor outputs a low-level signal. At this time, the device will issue an alarm. A detection hole 47 is provided on the mounting plate 20 at each corner corresponding to each accommodating space 23. The detection hole 47 is a circular through hole that vertically penetrates the mounting plate 20, and the inner wall of the hole is smooth and burr-free. The second position sensor 46 is also a diffuse infrared sensor. It is installed on the base 10 directly below the detection hole 47. The sensor head passes upward through the detection hole 47. When the mobile phone is correctly placed into the receiving space 23 and in place, the bottom of the mobile phone will reflect the infrared light emitted by the second position sensor 46. The sensor outputs a high-level signal, indicating that the mobile phone is installed in place. If the mobile phone is not placed or its position is offset after placement, resulting in the bottom not covering the detection hole 47, the sensor will not receive the reflected light and will output a low-level signal. The device will stop the test and indicate that the mobile phone position is abnormal.

[0037] Furthermore, it also includes: a data switching component 12, mounted on the base 10, for switching the test circuit between the test section and the connection section.

[0038] In this embodiment, the data switching component 12 is a multi-position rotary mechanical switch. Its housing is fixed to the side of the base 10 with screws, and the operating knob protrudes from the housing for easy rotation by the tester. The switch has multiple independent contact groups inside, each corresponding to a test circuit. The test circuit of the test unit and the external equipment circuit of the connection unit are respectively connected to the input and output terminals of the switch via wires. When the knob is rotated to different positions, the metal spring inside the switch connects the different input and output terminals, thereby switching the test circuit between the test unit and the connection unit.

[0039] In summary, the separate base 10 and mounting plate 20 facilitate rapid batch replacement of the equipment, improving testing efficiency. Multiple accommodating spaces 23 enhance the testing capacity and efficiency of the mounting plate 20. The separate base 10 and mounting plate 20 design eliminates the need for any adjustments to the base 10 when changing testing batches; simply remove the mounting plate 20 adapted to the current test batch and place the new one on the base 10. The entire process is simple and quick, significantly reducing changeover time compared to traditional fixtures that require disassembling multiple components. The multiple accommodating spaces 23 allow a single mounting plate 20 to hold multiple mobile phones simultaneously. During testing, the sliding connection module sequentially connects to the mobile phones in each accommodating space 23, enabling continuous testing of multiple phones. Compared to traditional fixtures that test only one phone at a time, testing efficiency is significantly improved.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
