Detailed Description

Please refer to fig. 1 and fig. 2. Fig. 1 is a schematic plan view of a testing apparatus disposed on a mobile station according to a first embodiment of the disclosure. Fig. 2 is a cross-sectional view of the test device of fig. 1.

In the embodiment, the testing device 1 is disposed on the movable stage 2, for example, and the testing device 1 includes a pressing head 5. The movable stage 2 can drive the pressing head 5 of the testing apparatus 1 to move along the Y, Z axis for testing the object 3. The object 3 to be measured is, for example, a key cap of a keyboard. The testing apparatus 1 performs a pressing test and a drawing test on the object 3 to be tested to ensure that the pressing feeling and the assembling adequacy of the keyboard meet the requirements, which will be described in detail below.

The pressing head 5 has a pressing member 10 and a drawing member 20. The pressing member 10 has a pressing portion 11 and an air-extracting passage 12, and the air-extracting passage 12 penetrates through the pressing portion 11. The pressing part 11 of the pressing member 10 is used for contacting the object 3 to be tested so as to perform a pressing test on the object 3 to be tested when the pressing member 10 is forced to move towards the object 3 to be tested. The drawing member 20 is, for example, an air-extracting element, and the drawing member 20 is connected to the air-extracting channel 12 for extracting air from the air-extracting channel 12 to perform a drawing test on the object 3 to be tested.

In the present embodiment, the testing apparatus 1 includes a pressure sensor 30, an air pressure sensor 40, and a controller 50 in addition to the pressing head 5.

The pressure sensor 30 is disposed on the pressing portion 11, and the air pressure sensor 40 is disposed on the pressing member 10 and located on the air exhaust channel 12. The controller 50 is connected to the pressure sensor 30 and the air pressure sensor 40 by signals, and adjusts the pumping intensity of the drawing member 20 and the pressing force of the pressing member 10 according to the pressure value sensed by the pressure sensor 30 and an air pressure value of the air pressure sensor 40.

Generally speaking, the requirements of the keyboards of different brands on the pressing force and the air-extracting strength are different, and the pressure sensor 30 and the air pressure sensor 40 are respectively used for sensing the pressing force of the pressing piece 10 pressing the object 3 to be tested and the air-extracting strength of the pulling piece 20, and determining whether the keyboard is the test standard of the keyboard. For example, if the pressing force of the object 3 to be tested is 60 g, the controller 50 can adjust the pressing force of the pressing element 10 when the pressing force is found to be insufficient or excessive. Similarly, if the suction strength of the object 3 to be tested is 1 kg, the controller 50 can adjust the suction strength of the drawing member 20 when the suction strength is found to be insufficient or too large.

In the present embodiment, the pressure sensor 30 is disposed in the pumping channel 12 for illustration purposes only, but not limited thereto. In other embodiments, the pressure sensor may instead be provided on the puller.

Next, a test method of the test apparatus 1 for testing the object 3 to be tested is explained. Referring to fig. 3 and 5, fig. 3 is a flowchart illustrating a testing method of the testing apparatus of fig. 1. Fig. 4 is a schematic plan view of the pressing member of fig. 1 pressing an object to be measured. Fig. 5 is a schematic plan view of the pressing member of fig. 1 sucking up the object to be measured.

As shown in fig. 3 and 4, first, in step S1, the pressing head 5 is pressed down along the Z-axis by the movable table 2, so that the object 3 to be tested is pressed by the pressing pieces 10 of the pressing head 5, thereby performing a pressing test on the object 3 to be tested. In general practical experience, a pressure test is performed before the keyboard leaves a factory, and the keycap of the keyboard is pressed by the pressing member 10, so that the pressure sensor 30 senses a change of the pressing force during the process of pressing the keycap, and an elastic curve is drawn. The elastic curve is the relationship between the stroke distance of the key cap pressing and the force of pressing the key cap, so that a manufacturer can judge whether the pressing hand feeling of the keyboard meets the requirement or not according to the elastic curve.

Next, the object 3 is suctioned from the suction passage 12 of the pressing member 10 by the drawing member 20 to make the pressing member 10 suck the object 3 as by step S2.

Next, in step S3, the pressing head 5 is lifted up along the Z-axis by the moving machine 2 to perform the pull-out test on the object 3, and the adhesion relationship between the pressing piece 10 of the pressing head 5 and the object 3 is used as the criterion for determining the installation quality of the object 3. In detail, as shown in fig. 2, if the pressing member 10 is separated from the object 3 during the process of being lifted, and the object 3 is kept at the original position, it represents that the installation quality of the object 3 meets the requirement. As shown in fig. 5, if the object 3 is sucked up by the pressing member 10 during the process of lifting up to separate the object 3, it represents that the mounting quality of the object 3 is poor.

In this embodiment, the installation quality of the object 3 can be determined not only by manually determining whether the object is sucked up, but also by observing the sensing value of the pressure sensor 30 or the air pressure sensor 40 when the pressing member 10 is lifted to a certain point. In detail, when the object 3 is sucked, the value sensed by the pressure sensor 30 or the air pressure sensor 40 keeps a specific value, but when the object 3 is not sucked, the change of the value sensed by the pressure sensor 30 or the air pressure sensor 40 is relatively obvious.

In the embodiment, after the pressing test of the pressing member 10 on the object 3 to be tested is completed, the object 3 to be tested is evacuated through the evacuation channel 12, so that the lifted pressing head 5 performs a pull test on the object 3 to be tested. Therefore, the test device 1 can perform the press test and the pull test on the object 3 to be tested together, so that not only different equipment can be saved for the press test and the pull test, but also the pull test can be performed without moving the object 3 to be tested after the press test is finished, thereby effectively reducing the cost and improving the test efficiency.

In the foregoing embodiments, the number of the pressing members 10 of the testing device 1 is one, and is not intended to limit the invention. Referring to fig. 6, fig. 6 is a schematic plan view of a testing apparatus according to a second embodiment of the disclosure.

In the present embodiment, the number of the pressing pieces 10 'is plural, and the pressing pieces 10' are relatively movable with each other in the Y-axis direction. The drawing member (as shown in fig. 1) is connected to the pumping channels 12 'of the pressing members 10' so that the testing apparatus can perform a pressing test and a drawing test on a plurality of objects to be tested 3 'through the pressing members 10' at a time.

According to the pressing piece, the testing device and the testing method disclosed by the embodiment, the pressing piece is provided with the air exhaust channel, and the pulling piece is communicated with the air exhaust channel of the pressing head, so that after the pressing piece performs the pressing test on the object to be tested, the object to be tested is exhausted through the air exhaust channel, and the lifted pressing head performs the pulling test on the object to be tested. Therefore, the test device can carry out the press test and the pull test on the object to be tested together, so that not only different equipment can be saved for the press test and the pull test, but also the pull test can be carried out without moving the object to be tested after the press test is finished, thereby effectively reducing the cost and improving the test efficiency.

Referring to fig. 7, fig. 7 is a schematic plan view of a testing apparatus according to a third embodiment of the disclosure. Another embodiment of the present invention provides a testing apparatus (as shown in fig. 1) that can be implemented without using a suction method, and the testing apparatus further includes a controller (as shown in fig. 1) and at least one pressing head 5 ″ controlled by the controller to move toward the object to be tested (as shown in fig. 1) for performing a pressing test and move away from the object to be tested for performing a drawing test. Wherein, each pressing head 5 "is provided with a pressing piece 10" and a drawing piece 20 ". When the pressing head 5 "is moved toward the object to be tested, the controller controls the drawing member 20" not to be actuated to perform the pressing test when the controller detects that the pressing member 10 "contacts the object to be tested. When the pressing test is finished, the controller controls the pulling piece 20 'to actuate and controls the pressing piece 10' to actuate to execute the drawing test.

The pressing member 10 "has a pressing fixed end 13" and a stretchable end 14 "connected to the pressing fixed end 13". The retractable end 14 "is retractable relative to the pressing head 5" and presses against the object to be tested during the pressing test. The pulling element 20 "has at least two pulling rods 21", each pulling rod 21 "having a pulling fixed end 211" and a spreading end 212 ". The drawing fixed end 211 "is fixedly connected with the pressing fixed end 13", and an end of the expanding end 212 "far away from the drawing fixed end 211" is provided with a claw 2121 "bent inwards, and the expanding ends 212" of at least two pull rods 21 "are separated from each other for being positioned at the periphery of the object to be tested during the pressing test and controlled by the controller to grasp the object to be tested through the claw 2121" during the drawing test, but not limited thereto. In other embodiments, the drawing piece is provided with two groups of pull rods, each group of pull rods comprises two pull rods, the two pull rods in the same group are connected through a transverse connecting rod to form a support, the two supports are connected through a spring, the controller controls the spring to enable the two supports to be opened and located on the periphery of the object to be tested when the pressing test is carried out, and the controller controls the spring to enable the two supports to be close to and grasp the object to be tested when the drawing test is carried out.
