Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 4, a pneumatic pressing jig for a USB expander includes a base plate 1, wherein a positioning carrier plate 2, a pressing cylinder 3 and a lower pressing block 4 are connected to the base plate 1; the pressing cylinder 3 is positioned right above the positioning carrier plate 2, and the lower pressing block 4 is connected with a piston rod of the pressing cylinder 3; the bottom plate 1 is further connected with a bearing seat 5 and a rotary cylinder 6, and one end of the lower pressing block 4 is rotatably connected to the bearing seat 5 and is in driving connection with the rotary cylinder 6. The positioning carrier plate 2 is used for positioning and placing the lower shell and the upper shell; the rotary cylinder 6 is used for driving the positioning carrier plate 2 to overturn and discharge along the bearing seat 5.

The pressing cylinder 3 is connected to the bottom plate 1 through a portal frame 31; the inner side of the portal frame 31 is connected with a vision camera 7, and the vision camera 7 is arranged towards the positioning carrier plate 2; one end of the bottom plate 1, which is close to the rotary cylinder 6, is connected with a selective blanking mechanism 8. The vision camera 7 is used for detecting whether the product after pressing is damaged or not, and the blanking mechanism 8 is selected to be used for screening good products and defective product blanking.

The selective blanking mechanism 8 comprises a three-way frame 81, a screening plate 82 and a telescopic cylinder 83; the bottom end of the screening plate 82 is hinged to the inner branch of the three-way frame 81, the bottom end of the screening plate 82 is hinged to one end of the telescopic cylinder 83, and the other end of the telescopic cylinder 83 is hinged to the bottom plate 1.

The USB interface positioning device is characterized in that a positioning placing groove 21 is formed in the positioning carrier plate 2, a yielding groove 22 is formed in the bottom surface of the positioning placing groove 21, the yielding groove 22 is used for yielding for the USB interface at the bottom end of the lower shell, and the depth of the positioning placing groove 21 is larger than the thickness of the lower shell and smaller than the thickness of the upper shell and the lower shell after being pressed.
