The blocking component 601 at the end of the first conveying part is used for preventing the subsequent keyboard to be tested from entering the testing position when the carrier and the keyboard are already present at the testing position. When the carrier reaches the top of the second support structure 302 together with the keyboard, the blocking component 601 at the end of the second conveying part is used for preventing the carrier from further advancing, so that the keyboard is conveniently conveyed into the testing position.
Further, the blocking assembly 601 comprises a third pneumatic rod 602, the third pneumatic rod 602 being located at the bottom of the blocking assembly 601 for raising or lowering the top level of the blocking assembly 601. When the blocking component 601 works, the third air pressure rod 602 stretches, and when the blocking component 601 does not work, the third air pressure rod 602 shortens.
In some examples, the blocking assembly 601 further includes a roller 603, the roller 603 being on top of the blocking assembly 601. When the blocking component 601 does not work, in order to avoid that the top of the blocking component 601 contacts the carrier, the carrier is prevented from moving, the roller 603 abuts against the bottom of the carrier and rotates along with the movement of the carrier, and rolling friction is used for replacing sliding friction.
In the description of the present specification, if a description appears that makes reference to the term "one embodiment," "some examples," "some embodiments," "an exemplary embodiment," "an example," "a particular example," or "some examples," etc., it is intended that the particular feature, structure, material, or characteristic described in connection with the embodiment or example be included in at least one embodiment or example of the invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
