[0028] The utility model is an anti-lateral thrust detection device for a notebook computer touch control module. As shown in Figure 1 , the device at least includes: an X-axis drive module 2, a Y-axis drive module 3, a push head module 4, and a fixture 9 for positioning the touch control module.
[0029] The push head module 4 is driven by the X-axis drive module 2 and the Y-axis drive module 3 to move in the X / Y directions. The push head module 4 includes: a pressure sensor 43 and a push rod 44 arranged on the pressure sensor 43. The fixture 9 is located in the Y-axis running direction of the push head module 4.
[0030] During operation, the push rod 44 in the push head module 4 is set at the same height as the touch module 90 positioned in the fixture 9. Then, driven by the Y-axis drive module 3, the push rod 44 moves towards the fixture 9, causing the push rod 44 to exert a thrust on the side of the touch module 90 positioned on the fixture 9. The thrust generated by the push rod 44 can be displayed by the pressure sensor 43. The displacement of the glass plate in the touch module 90 can be displayed by an external CCD vision lens, or directly observed by the naked eye or magnifying glass. When the displacement of the glass plate in the touch module 90 exceeds the limit, record the thrust value of the push rod 44 at this time.
[0031] In addition, the X-axis drive module 2 can detect the relevant parameters of the lateral thrust resistance at different positions on the side of the touch module 90. Finally, based on the relationship between the thrust values and displacement amounts at different positions, determine whether the touch module meets the design requirements.
[0032] See Figures 2 to 8 As shown, the X-axis drive module 2, Y-axis drive module 3, push head module 4, and fixture 9 are all installed on the bottom plate 11.
[0033] To ensure the operation accuracy, the X-axis drive module 2 and Y-axis drive module 3 adopt linear motors, such as the linear motor of ISPB-SXM. The specific structure of the X / Y operation mechanism formed by the X-axis drive module 2 and Y-axis drive module 3 is as follows:
[0034] The X-axis drive module 2 is arranged on the bottom plate 11. An X-axis carrier plate 20 is arranged on the X-axis drive module 2, and the X-axis carrier plate 20 is fixedly connected to the X-axis slider 21 in the X-axis drive module 2, so as to realize that the X-axis carrier plate 20 will move along the X-axis driven by the X-axis drive module 2.
[0035] The present utility model adopts a set of X-axis drive modules 2. To ensure the smooth operation of the X-axis carrier plate 20, an auxiliary slide rail mechanism 22 is arranged between the X-axis carrier plate 20 and the bottom plate 11.

The smooth operation of the X-axis carrier plate 20 can be realized through the X-axis drive module 2 and the auxiliary slide rail mechanism 22.
[0036] To accurately detect the operation accuracy of the X-axis drive module 2, an X-axis grating ruler 5 is arranged on one side of the X-axis carrier plate 20. Combined with Figure 7As shown, the head of the X-axis grating scale 5 is fixedly connected to the X-axis carrier plate 20 or the X-axis slider 21. The base of the X-axis grating scale 5 is fixed on the bottom plate 11, and the base of the X-axis grating scale 5 is parallel to the running direction of the X-axis driving module 2. The running distance of the X-axis driving module 2 can be accurately measured by the X-axis grating scale 5.

The X-axis signal element 61 can adopt an infrared trigger, and the X-axis trigger 62 can adopt a baffle. When the X-axis trigger 62 passes by the X-axis signal element 61, the X-axis signal element 61 is triggered, thereby determining the running position of the X-axis slider 21.
[0038] The Y-axis driving module 3 is installed on the X-axis carrier plate 20. The push head module 4 is arranged on the Y-axis driving module 3. Similarly, on the side of the Y-axis driving module 3, there is a Y-axis position detection unit 8, and on the other side of the push head module 4 opposite to the Y-axis position detection unit 8, there is a Y-axis grating scale 7.

The height of the pressure sensor 43 and the push rod 44 can be adjusted by adjusting bolts, so that the push rod 44 can accurately act on the side of the touch module.
[0041] In order to avoid damaging the touch module, a rubber sleeve 440 is installed at the end of the push rod 44.
[0042] The fixture 9 is fixed on the bottom plate 11 through the support base 91, and the platform height of the fixture 9 corresponds to the height of the push rod 44. Subsequently, for different products, the height of the push rod 44 can be adjusted by the Z-axis adjustment slide 42.
[0043] See Figure 9 As shown, this is a perspective view of the detection device 1 of the present utility model, which includes: a base 12 and a control box 13.
