Description

Technical Field

[0001] This invention relates to the technical field of electronic product testing, and in particular to an XY-axis virtual force application testing device. Background Technology

[0002] In the manufacturing of foldable screen phones, testing the axial and normal push-pull force of the hinge for misalignment is a crucial process. Current manufacturing processes use manual fixtures to position the foldable screen phone and apply a force to the mid-frame using cylinders and springs. Misalignment is then measured using a displacement meter. However, the use of cylinders results in high impact force and low stability, and the magnitude of the applied force cannot be monitored, making it incompatible with changes in required force during product redesigns. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an XY-direction virtual force application test device with good force application stability, ability to monitor the applied force value and good compatibility.

[0004] The technical solution adopted in this invention is as follows: This invention includes a product fixture, a Y-axis virtual force application component, a Y-axis virtual imaging component, an X-axis virtual force application component, and an X-axis virtual imaging component. The Y-axis virtual force application component includes a first linear module in the Z-axis direction. The driving end of the first linear module is provided with a second linear module in the Y-axis direction. The driving end of the second linear module is provided with a first double-layer spring assembly. The driving end of the first double-layer spring assembly is provided with a first pressure sensor. The first pressure sensor is provided with a Y-axis force application part. The Y-axis virtual imaging component captures the displacement of the product when the Y-axis force application part applies force to the product.

[0005] The X-axis virtual force application component is a third linear module in the Z-axis direction. The driving end of the third linear module is provided with a fourth linear module in the X-axis direction. The driving end of the fourth linear module is provided with a second double-layer spring assembly. The driving end of the second double-layer spring assembly is provided with a second pressure sensor. The second pressure sensor is provided with an X-axis force application part. The X-axis virtual imaging component captures the displacement of the product when the X-axis force application part applies force to the product.

[0006] Furthermore, both the first double-layer spring assembly and the second double-layer spring assembly include a first movable seat, a first slider, and a second slider. The first movable seat is provided with a first guide post, the first slider is slidably engaged with the first guide post, the first guide post is provided with a first spring connected to the first slider, the first slider is provided with a second movable seat, the second movable seat is provided with a second guide post, the second slider is slidably engaged with the second guide post, and the second guide post is provided with a second spring connected to the second slider.

[0007] Furthermore, the product fixture is equipped with a product spinning cover plate and a clamping push rod.

[0008] Furthermore, both the X-axis virtual imaging component and the Y-axis virtual imaging component include an XYZ adjustment slide and a camera module, with the camera module disposed on the adjustment end of the XYZ adjustment slide.

[0009] Furthermore, the Y-axis dummy force application component and the X-axis dummy force application component are located above and below the product fixture, respectively.

[0010] Furthermore, the first linear module includes a first fixed base, on which a clamping cylinder and a first guide shaft are disposed. The driving end of the clamping cylinder is connected to the second linear module, and a first linear bearing is disposed on the first guide shaft, which is connected to the second linear module.

[0012] Furthermore, the Y-direction virtual force application component also includes a pressing component, which presses the material when the Y-direction force application part applies force to the product.

[0013] The beneficial effects of this invention are:

[0014] Compared to the shortcomings of existing technologies, in this invention, the first and second linear modules apply force to the product by driving the Y-axis force-applying part through the first double-layer spring assembly. This avoids the large impact force that occurs when the traditional technology directly uses a cylinder to apply force. Furthermore, the magnitude of the applied force is monitored by a first pressure sensor, making the force application more stable. Similarly, the third and fourth linear modules apply force to the product by driving the X-axis force-applying part through the second double-layer spring assembly.

The magnitude of the applied force is monitored by a second pressure sensor, making the force application more stable. In addition, this invention has good compatibility after product redesign. Therefore, this invention has the advantages of good force application stability, monitorable applied force value, and good compatibility. Attached Figure Description

[0028] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a product fixture 1, a Y-axis virtual force application component 2, a Y-axis virtual imaging component 3, an X-axis virtual force application component 5, and an X-axis virtual imaging component 6. The Y-axis virtual force application component 2 includes a first linear module 7 in the Z-axis direction. The driving end of the first linear module 7 is provided with a second linear module 8 in the Y-axis direction. The driving end of the second linear module 8 is provided with a first double-layer spring assembly 9. The driving end of the first double-layer spring assembly 9 is provided with a first pressure sensor 10. The first pressure sensor 10 is provided with a Y-axis force application part 11. The Y-axis virtual imaging component 3 captures the displacement of the product when the Y-axis force application part 11 applies force to the product.

[0029] The X-direction virtual force application component 5 is a third linear module 12 in the Z direction. The driving end of the third linear module 12 is provided with a fourth linear module 13 in the X direction. The driving end of the fourth linear module 13 is provided with a second double-layer spring assembly 15. The driving end of the second double-layer spring assembly 15 is provided with a second pressure sensor 16. The second pressure sensor 16 is provided with an X-direction force application part 17. The X-direction virtual imaging component 6 captures the displacement of the product when the X-direction force application part 17 applies force to the product.

[0030] Among them, the product fixture 1 is used to position the product to prevent the product from shaking during the force test and affecting the test results; during the virtual position test, the hinge 41 of the foldable screen phone is assembled with the middle frame 42 and placed on the product fixture 1 for positioning. Then, the Y-direction virtual position force application component 2 and the X-direction virtual position force application component 5 apply Y-direction and X-direction forces to the outside of the product respectively, and the Y-direction virtual position photography component 3 and the X-direction virtual position photography component 6 capture the positional offset of the product before and after the force is applied for testing.

[0031] It should be noted that the first linear module 7 is a clamping cylinder, which presses down to clamp the product fixture 1. The second linear module 8 drives the Y-axis force application part 11 to apply a Y-axis push-pull force to the product, and the magnitude of the applied force is monitored by the first pressure sensor 10. Similarly, the third linear module 12 is a lifting cylinder, which lifts the product to the force application position. The fourth linear module 13 drives the X-axis force application part to apply an X-axis push-pull force to the product, and the magnitude of the applied force is monitored by the second pressure sensor 16.

[0032] Compared to the shortcomings of existing technologies, in this invention, the first linear module 7 and the second linear module 8 apply force to the product by driving the Y-axis force application part 11 through the first double-layer spring assembly 9. This avoids the large impact force that occurs when the traditional technology directly uses a cylinder to apply force. Furthermore, the magnitude of the applied force is monitored by the first pressure sensor 10, making the force application more stable. Similarly, the third linear module 12 and the fourth linear module 13 apply force to the product by driving the X-axis force application part through the second double-layer spring assembly 15. This avoids the large impact force that occurs when the traditional technology directly uses a cylinder to apply force. Furthermore, the magnitude of the applied force is monitored by the second pressure sensor 16, making the force application more stable. In addition, this invention has good compatibility after product redesign. Therefore, this invention has the advantages of good force application stability, monitorable applied force value, and good compatibility.

[0033] like Figure 4As shown, in some embodiments, both the first double-layer spring assembly 9 and the second double-layer spring assembly 15 include a first movable seat 18, a first slider 19, and a second slider 20. A first guide post 21 is disposed on the first movable seat 18, and the first slider 19 is slidably engaged with the first guide post 21. A first spring 22 connected to the first slider 19 is disposed on the first guide post 21. A second movable seat 23 is disposed on the first slider 19, and a second guide post 25 is disposed on the second movable seat 23. The second slider 20 is slidably engaged with the second guide post 25, and a second spring 26 connected to the second slider 20 is disposed on the second guide post 25. The first movable seat 18 is connected to the first linear module 7 / third linear module 12, and the second slider 20 is connected to the first pressure sensor 10 / second pressure sensor 16. The first slider 19 and the second slider 20 are offset in the Z-direction.

[0034] It should be noted that when the first movable seat 18 moves to one side, the first slider 19 can slide on the first guide post 21 and compress the first spring 22, so that the Y-direction force application part 11 / X-direction force application part applies a flexible pushing / pulling force to the product; when the first movable seat 18 moves to the other side, the second slider 20 can slide on the second guide post 25 and compress the second spring 26, so that the Y-direction force application part 11 / X-direction force application part applies a flexible pulling / pushing force to the product. Therefore, through the arrangement of the first double-layer spring assembly 9 and the second double-layer spring assembly 15, the force application can remain stable when the Y-direction force application part 11 / X-direction force application part applies a pushing or pulling force to the product.

[0035] like Figure 5 As shown, in some embodiments, the product fixture 1 is provided with a product pressing cover plate 27 and a clamping push rod 28. Specifically, the product pressing cover plate 27 is rotatably fitted onto the product fixture 1, so that after the clamping push rod 28 presses against the middle frame 42, the product pressing cover plate 27 is rotated and pressed onto the middle frame 42 to achieve product positioning and prevent the product from shaking during force testing.

[0036] like Figure 6 As shown, in some embodiments, both the X-axis virtual imaging component 6 and the Y-axis virtual imaging component 3 include an XYZ adjustment slide 29 and a camera module 30, with the camera module 30 disposed on the adjustment end of the XYZ adjustment slide 29. Specifically, adjusting the camera module 30 via the XYZ adjustment slide 29 can improve compatibility after product redesign.

[0037] In some embodiments, the Y-direction dummy force application component 2 and the X-direction dummy force application component 5 are located above and below the product fixture 1, respectively.

[0038] like Figure 2As shown, in some embodiments, the first linear module 7 includes a first fixed base 31, on which a clamping cylinder 32 and a first guide shaft 33 are provided. The driving end of the clamping cylinder 32 is connected to the second linear module 8. A first linear bearing 35 is provided on the first guide shaft 33, and the first guide shaft 33 is connected to the second linear module 8.

[0039] like Figure 3 As shown, in some embodiments, the third linear module 12 includes a second fixed base 36, on which a lifting cylinder 37 and a second guide shaft 38 are provided. The driving end of the lifting cylinder 37 is connected to the fourth linear module 13. A second linear bearing 39 is provided on the second guide shaft 38, and the second guide shaft 38 is connected to the fourth linear module 13.

[0040] In some embodiments, the Y-direction dummy force application component 2 further includes a pressing component, which presses the product down when the Y-direction force application part 11 applies force to it. Specifically, when the Y-direction force application part 11 applies force to the product, pressing the product down with the pressing component can prevent the product from tilting up, thereby improving stability during force application.
