[0038] Example:

[0039] In order to better understand the structure of the present crimping mechanism, the structure of the VR module 100 is now described:

[0040] Figure 1 is a schematic diagram of the structure of a VR module provided by an embodiment of the present invention, such as Figure 1 As shown, the VR module 100 includes a body, a connector 101 and a display screen 102, wherein the connector 101 is located on the top surface of the body, the display screen 102 is located on a side surface of the body, and the outer surface of the body is an irregular shape.

[0041] Figure 2 is a first view of a crimping mechanism of a VR module provided by an embodiment of the present invention, Figure 3 is a second view of a crimping mechanism of a VR module provided by an embodiment of the present invention, combined with Figure 2 and Figure 3 As shown, the crimping mechanism includes a base 1 , a support block 2 , a pressing block 3 , a crimping module 4 and a lifting module 5 .

[0042] The support block 2 and the lifting module 5 are both located on the base 1 .

[0043] Figure 4 yes Figure 2 A partial enlarged view of area A, such as Figure 4 As shown, the support block 2 has a support surface, and the support surface has a plurality of positioning pins 21 arranged at intervals, and each positioning pin 21 is used to be inserted into a positioning hole of the VR module 100.

[0044] Figure 5 Schematic diagram of the structure of the pressing block provided by the embodiment of the present invention. Figure 5 As shown, the pressing block 3 is slidably arranged on the base 1, and the pressing block 3 has a slope 31 on the side facing the support block 2 to obliquely press the connector 101 of the VR module 100 on the support block 2. The pressing block 3 has a through hole 32 for facing the display screen 102 on the VR module 100. The crimping module 4 is used to crimp and conduct the VR module 100. The output end of the lifting module 5 is transmission-connected to the crimping module 4 to drive the crimping module 4 to rise and fall relative to the support block 2.

[0045] For a crimping mechanism of a VR module provided by an embodiment of the present invention, when crimping and lighting up a miniature and special-shaped VR module 100, first, the VR module 100 is placed on the support surface on the support block 2, and each positioning pin 21 is inserted into the corresponding positioning hole on the VR module 100. Through the cooperation of the positioning pin 21 and the positioning hole, the VR module 100 can be positioned in the horizontal direction. At this time, the connector 101 of the VR module 100 is located on its top surface and arranged upward, while the display screen 102 of the VR module 100 is located on the side and arranged toward the pressing block 3. Then, the pressing block 3 is slid so that the inclined surface 31 presses the VR module 100 obliquely. The oblique pressing will form a compression in both the horizontal and vertical directions, and with the cooperation of the positioning pin 21 and the positioning hole, the VR module 100 is finally accurately positioned in three-dimensional space, which can not only prevent its movement, but also ensure the accuracy in the subsequent crimping process. Next, the crimping module 4 is lowered by the lifting module 5, thereby connecting the connector 101 of the VR module 100, thereby lighting up the display screen 102 on the VR module 100. Finally, a camera module is provided so that the lens of the camera module is directly opposite to the through hole 32, and the display screen 102 on the VR module 100 is photographed by the camera module. The pressure head 42 will not interfere with the camera module's photography, and the display performance of the VR module 100 is finally determined by analyzing and processing the photos, completing the test.

[0046] That is to say, the crimping mechanism of a VR module provided by an embodiment of the present invention can not only realize the precise positioning of the VR module 100 in three-dimensional space, but also avoid the problem that the positioning structure (i.e., the pressure head 42 of the crimping mechanism) interferes with the camera module taking pictures.

[0047] It is easy to understand that the present crimping mechanism has high positioning accuracy through the cooperation of the positioning pin 21 and the positioning hole, and the oblique pressing of the pressing block 3, and is particularly suitable for miniature VR modules 100. In addition, during positioning, the contact area between the crimping mechanism and the VR module 100 is small, which reduces the risk of damage, and reduces the difficulty of positioning compared to the traditional positioning block clamping positioning method, and is particularly suitable for special-shaped VR modules 100 with irregular outer surfaces.

[0048] For example, the dimensions of the VR module 100 may be: 10-20 mm in length, 10-20 mm in width, and 10-20 mm in height. The angle between the inclined surface 31 and the supporting surface may be 50-80°.

[0049] Preferably, the inclined surface 31 of the pressing block 3 may be parallel to an inclined side surface of the VR module 100 , so that the VR module 100 is more stable when being pressed obliquely.

[0050] See also Figure 4 The base 1 has a positioning block 14 , and a positioning groove 141 is provided on the side of the positioning block 14 . One side of the support block 2 is inserted into the positioning groove 141 , and the pressing block 3 is located on the positioning block 14 .

[0051] In the above embodiment, the positioning groove 141 on the positioning block 14 can be used to position the support block 2 , and the support block 2 can also be lifted to facilitate driving the pressing block 3 to move.

[0052] Furthermore, the positioning block 14 has a plurality of blowing holes 142 arranged at intervals, each of the blowing holes 142 is connected to the positioning groove 141 , and each of the blowing holes 142 is used to blow air into the VR module 100 .

[0053] It is easy to understand that the heat dissipation area of ​​the miniature VR module 100 is small due to its small size, so the heat is not easy to volatilize after it is turned on. By arranging multiple blowing holes 142 on the positioning block 14, blowing through the blowing holes 142 can accelerate air circulation, which is convenient for rapid heat dissipation of the VR module 100.

[0054] Exemplarily, the positioning block 14 has an airway, one end of which is connected to each blowing hole 142, and the other end of which is plugged with a trachea connector 15. The airway serves to connect the trachea connector 15 and the blowing hole 142, and the trachea connector 15 is convenient for connecting with the air source.

[0055] In one implementation of the present invention, the positioning block 14 has a plurality of guide grooves 143 arranged at intervals, and the crimping module 4 has a plurality of guide rods 41 arranged at intervals, and each guide rod 41 can be movably inserted into a corresponding guide groove 143. When the crimping module 4 is in the process of descending, the guide rods 41 on the crimping module 4 cooperate with the guide grooves 143, thereby ensuring the pressing accuracy of the crimping module 4.

[0056] Figure 6 is a cross-sectional view of a pressing block provided by an embodiment of the present invention, such as Figure 6 As shown, the base 1 has a plurality of guide shafts 11 arranged at intervals, and the pressure block 3 can be slidably mounted on the plurality of guide shafts 11. A limit head 12 is arranged at one end of each guide shaft 11, and a spring 13 is mounted on each guide shaft 11, and the two ends of the spring 13 are respectively against the corresponding limit head 12 and the pressure block 3.

[0057] Specifically, before placing the VR module 100, the elastic force of the spring 13 is overcome by external force, so that the pressing block 3 retreats relative to the supporting block 2. Then, the VR module 100 is placed (at this time, the inclined surface 31 on the pressing block 3 is not in contact with the VR module 100), and the external force is removed. Under the action of the elastic force of the spring 13, the pressing block 3 will slide along the guide shaft 11, and finally its inclined surface 31 will obliquely press the VR module 100. Under the elastic force of the spring 13, the pressing block 3 can always be kept in a compressed state, avoiding the problem of continuous pressing by external force.

[0058] For example, the guide shaft 11 is arranged horizontally, and its right end is inserted and fixed on the positioning block 14. The pressing block 3 is an L-shaped structure, and the inclined surface 31 is located on the vertical part of the pressing block 3. The guide shaft 11 is inserted on the horizontal part of the pressing block 3, and the left end of the horizontal part of the pressing block 3 is connected to the vertical part, and the cover is arranged on the outer periphery of the spring 13 and the limit head 12 to play a protective role. The right end of the horizontal part of the pressing block 3 is slidably matched with the guide shaft 11 (see Figure 6 ).

[0059] Furthermore, the crimping mechanism further comprises a lever 6 , a middle portion of which is rotatably arranged on the base 1 , and one end of the lever 6 abuts against the pressing block 3 to drive the pressing block 3 to slide back toward the supporting block 2 .

[0060] In the above embodiment, by pressing the other end of the lever 6 (i.e. Figure 6 The lower end in the middle) can make one end of the pressing lever 6 rotate, thereby conveniently pushing the pressing block 3 to slide, which is more labor-saving.

[0061] Exemplarily, the lever 6 is located on the positioning block 14 .

[0062] See again Figure 2The crimping mechanism further includes a transverse movement module 7, which is located on the base 1, and an output end of the transverse movement module 7 is transmission-connected to the lifting module 5 to drive the lifting module 5 to move transversely.

[0063] In the above embodiment, the lifting module 5 can be driven to move horizontally through the transverse movement module 7, thereby causing the crimping module 4 to move horizontally, which can also make the crimping module 4 move backward, thereby facilitating the placement of the VR module 100 and avoiding the crimping module 4 from interfering with the placement of the VR module 100.

[0064] Exemplarily, the lifting module 5 and the lateral movement module 7 may be cylinders or linear modules, which is not limited in the present invention.

[0065] In this embodiment, the crimping module 4 includes a crimping head 42, a transfer PCB board 43 and a probe module 44. The transfer PCB board 43 is located on the crimping head 42, the probe module 44 is inserted into the crimping head 42, and a conductive portion of the probe module 44 (i.e., the top of the probe) is connected to the transfer PCB board 43, and another conductive portion of the probe module 44 (i.e., the bottom of the probe) is used to crimp the connector 101 of the VR module 100. The output end of the lifting module 5 is transmission-connected to the crimping head 42. A test PCB board 16 is provided on the base 1, and the test PCB board 16 is connected to the transfer PCB board 43 through a flat cable 17.

[0066] In the above embodiment, the lifting module 5 drives the pressure head 42 to descend, which can cause the probe module 44 and the adapter PCB board 43 to descend, so that the other conductive part of the probe module 44 is connected to the connector 101 of the VR module 100. On this basis, by providing a test signal to the test PCB board 16, the test signal passes through the flat cable 17, the adapter PCB board 43 and the probe module 44, and finally realizes the lighting of the display screen 102 of the VR module 100.

[0067] Exemplarily, the transverse movement module 7 has a plurality of cable pressing blocks 71 for pressing the cable 17 .

[0068] Figure 7 is a flow chart of a method for testing a VR module provided by an embodiment of the present invention. Figure 7 As shown, the test method is based on the above-mentioned crimping mechanism, and the test method includes:

[0069] S1. Place the VR module 100 on the support surface of the support block 2 , and insert each positioning pin 21 into the corresponding positioning hole on the VR module 100 .

[0070] S2. Slide the pressing block 3 so that the inclined surface 31 presses the VR module 100 obliquely to achieve positioning of the VR module 100 in three-dimensional space.

[0071] S3. Lift and lower the crimping module 4 through the lifting module 5 to light up the display screen 102 on the VR module 100.

[0072] S4. Provide a camera module so that the lens of the camera module is directly opposite to the through hole 32, and take a picture of the display screen 102 on the VR module 100 through the camera module.

[0073] The VR module testing method provided by the embodiment of the present invention not only realizes the precise positioning of the VR module 100 in three-dimensional space, but also avoids the problem of the positioning structure interfering with the camera module's photography.

[0074] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
