In this way, a one-stage press test on the stress warping condition of the logic upper cover and the logic lower cover at the front corners of the laptop computer shell to be tested can be completed. The press test of this stage can be repeated twice or three times to finally complete the final test on the stress warping condition of the logic upper cover and the logic lower cover at the front corners of the laptop computer shell to be tested.

[0059] Compared with the prior art method of manually testing the stress and warping conditions of laptop computer shell parts, the press test device provided in the embodiment of the present disclosure can fully realize automatic testing or semi-automatic testing, and the test parameters can be accurately adjusted during the entire testing process, effectively avoiding the problem of test errors, and has the beneficial effect of fully meeting the test accuracy requirements.

In addition, the clamping claw 43 is set in the swing arm 42 to clamp the opening and closing part of the laptop computer to be tested and drive it to rotate synchronously with the swing arm 42, so that the laptop computer to be tested can be opened at a fixed angle.

[0066] The specific configuration of the swing opening and closing mechanism 4 has the beneficial effects of simple structure and the ability to accurately control the opening angle of the notebook computer.

[0067] Of course, the clamping claw member 43 in the swing opening and closing mechanism 4 can also be configured as a suction member, and fixedly connected with the opening and closing part of the laptop computer to be tested by vacuum adsorption.

[0068] In one embodiment, the swing arm 42 is provided with a slide groove 421 extending along its own length direction; the clamping jaw 43 has an adjustment seat 431 that is clamped with the slide groove 421, and a clamping jaw head 432 for opening and closing clamping; wherein, the adjustment seat 431 can slide to adjust its own fixed clamping position in the slide groove 421; the clamping jaw head 432 has a movable clamp and a fixed clamp, and the movable clamp can adjust the clamping distance with the fixed clamp.

[0069] Specific, combined Figure 3 To further explain, a slide groove 421 extending along the length direction of the swing arm 42 is opened, and the clamping jaw member 43 has an adjusting seat 431 that is clamped with the slide groove 421, so that the clamping jaw member 43 can adjust its relatively fixed installation position in the swing arm 42 through the adjusting seat 431, so that the clamping jaw member 43 can be more flexibly adapted to clamping the parts to be opened and closed in the equipment to be tested of different sizes and models; moreover, the clamping jaw member 43 also has a clamping jaw head 432 for opening and closing clamping, and the clamping jaw head 432 can be but is not limited to being driven by a cylinder, and the cylinder is used to drive the movable clamp in the clamping jaw head 432 to move toward or away from the fixed clamp, thereby realizing the function of gripping or releasing the clamping jaw head 432.

[0070] The specific arrangement of the swing arm 42 and the clamping claw 43 has the beneficial effects of being simple in structure and being able to be flexibly adjusted to adapt to components of different sizes to be opened and closed.

[0071] In one embodiment, the clamping mechanism 3 includes a lifting clamp head 31 and a lifting drive 32; the lifting clamp head 31 can be lifted and lowered and inserted into the test platform 1; the lifting drive 32 is transmission-connected to the lifting clamp head 31, and is used to drive the lifting clamp head 31 to lift and lower, and drive the lifting clamp head 31 to rotate around the lifting direction and / or translate along the test platform 1.

[0072] Specific, combined Figure 4 Further explanation, the above-mentioned clamping mechanism 3 can be specifically arranged in multiple on the test platform 1, for example, multiple clamping mechanisms 3 are arranged around the periphery of the device to be tested in a rectangular array. In addition, the clamping mechanism 3 is specifically arranged to include a lifting clamping head 31 and a lifting driver 32, and the lifting driver 32 is not only arranged to be able to drive the lifting clamping head 31 to move up and down, but also to correspondingly drive the lifting clamping head 31 to rotate around the lifting direction and / or move horizontally along the test platform 1, so that when the clamping mechanism 3 is reset, the lifting clamping head 31 can be first driven to rise to a certain height by the lifting driver 32, and then the lifting clamping head 31 can be correspondingly driven to rotate or move away from the device to be tested, so that the device to be tested is no longer clamped and limited by the clamping mechanism 3. Similarly, when the clamping mechanism 3 needs to clamp and limit the device to be tested, it only needs to first drive the lifting clamping head 31 to rotate or move toward the device to be tested by the lifting driver 32, and then drive the lifting clamping head 31 to descend and press the device to be tested by the lifting driver 32.

[0073] Moreover, the above-mentioned lifting driver 32 can be specifically but not limited to being set up in a "cylinder + driving motor" mode, where the cylinder drives the lifting clamping head 31 to rise or fall, and the driving motor drives the lifting clamping head 31 to rotate or move.

[0080] The specific configuration of the gravity load mechanism 6 has the beneficial effects of being simple in structure and being able to flexibly and quickly perform the load pressurization function.

[0081] In one embodiment, the load arm 62 is provided with an adjustment slot 621 extending along its length direction; the load pressure head 63 is clamped in the adjustment slot 621 and can slide to adjust its fixed clamping position in the adjustment slot 621 .
