Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. Only this statement, the utility model discloses the upper and lower, left and right, preceding, back, inside and outside etc. position words that appear or will appear in the text only use the utility model discloses an attached drawing is the benchmark, and it is not right the utility model discloses a concrete restriction.

As shown in fig. 1-4, the embodiment of the utility model provides a door window lift button testing arrangement, including testboard 1, arm 2, connector 3, profile modeling hook 4, distance sensor 5, force sensor 6. And the test board 1 is provided with a corresponding clamp for fixing a vehicle window lifting button 7 to be detected. The profiling hook 4 is connected with the mechanical arm 2 through a connecting body 3. The mechanical arm 2 is a six-axis movable mechanical arm 2 and is used for driving the profiling hook 4 to move in three dimensions; the distance sensor 5 and the force sensor 6 are both arranged on the connecting body 3 and are used for detecting the displacement and stress of the profiling hook 4; the profiling hook 4 is provided with a pressing part for pressing the window lifting button 7 and a pulling part for pulling up the window lifting button 7.

Specifically, the profiling hook 4 comprises a hook body 41, a first pulley 42 is arranged at the lower end of the hook body 41, a second pulley 43 is arranged at the upper end of the hook body 41, and the first pulley 42 and the hook body 41 are matched to form a lifting part; the second pulley 43 cooperates with the hook 41 to form a pressing portion.

In order to reduce the influence of lateral torsion on the force sensor 6, the profile hook 4 is connected to a connecting shaft 31, and the connecting shaft 31 extends into a guide block 32. The guide block 32 is provided with a guide hole 33, the connecting shaft 31 extends into the guide hole 33, and the upper side and the lower side of the guide block 32 are respectively provided with a limiting ring 34. The force sensor 6 is arranged at the tail end of the connecting shaft 31, and the fragile force sensor 6 is prevented from being damaged by collision. The connecting body 3 is provided with a mounting hole 35 for fixing the guide block 32, and the distance between the limiting rings 34 on the upper and lower sides is greater than the thickness of the mounting hole 35, so that the guide block 32 can slightly move axially relative to the mounting hole 35. The torsion and non-axial force applied to the copying hook 4 can be offset by the guide block 32, and the detection deviation of different buttons caused by slight difference of pressing directions can be reduced.

Preferably, the distance sensor 5 is provided on a side surface of the connection body 3. The distance sensor 5 is preferably a laser distance measuring device that detects the displacement of the connecting body 3 by emitting laser light, thereby estimating the position of the copying hook 4.

Taking a car window button pressing test as an example, the detection principle of the device is as follows:

firstly, fixing a vehicle window lifting button 7 to be detected on a test board 1, arranging an output lead wire 71 on the vehicle window lifting button 7, and connecting the output lead wire 71 with a collection card. Under normal conditions, when the window up-down button 7 is pressed or pulled, the corresponding output lead wire 71 is conducted, so that the control of the window up-down is realized. The acquisition card can detect whether the corresponding lead of the car window lifting button 7 is conducted or not and record related data. The profiling hook 4 is moved by the robot arm 2 to about 5mm above the button and then moved downwards. The second pulley 43 of the copying hook 4 is in contact with the window regulator button 7 and continues to press the window regulator button 7, and when the force sensor 6 senses the force (0.1N), it is determined that the product is initially contacted. The current data of the distance sensor 5 is recorded. When the acquisition card acquires voltage from an open circuit to a short circuit, the conduction of the vehicle window switch is judged, and relevant data such as displacement data, pressure data and the like are recorded, so that whether the switch state (voltage drop, conduction angle and conduction force) is normal or not is judged.

The window button pull-up test is similar to the push-down test in that the copying hook 4 is hooked into the button and moved upward, and the button is pulled upward by the first pulley 42.

Adopt this testing arrangement, the tester only need put into the product that awaits measuring alright test, convenient to use, and the testing process is automatic goes on, can acquire the parameter that is used for judging the button quality simultaneously, detects fast and accurate.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
