connecting rod 67 moves upwards and resets under the action of the recovery spring 66, so as to drive the recovery gear 64 to move upwards through the connecting block 65, so as to gradually separate the recovery gear 64 from the meshing with the intermediate gear 31 and start the splined connection with the lifting shaft 25, when the lifting plate 69 moves upwards to be separated from the connecting rod 67, the recovery gear 64 is completely separated from the meshing with the intermediate gear 31, and further the, when the lifting plate 69 is completely separated from the connecting rod 67, the recovery gear 64 stops lifting, then the main motor 38 is closed, the electromagnet 35 is closed, then the display 50 is pulled upwards, further the display 50 is separated from the adsorption plate 49, and then the display 50 is taken out, so that the reciprocating operation is performed.
The beneficial effects are that: the invention can repeatedly damage the display screen of the LED display and the interface, thereby detecting whether the damage resistance of the display screen of the LED display and the interface reaches the standard, being beneficial to improving the product quality, ensuring that the plug insertion mode and the insertion depth are communicated each time, thereby reducing errors as much as possible, ensuring the detection accuracy, and simultaneously cleaning the display screen of the LED display, and avoiding foreign matters from mixing to influence the detection result.
The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
