Its specific functions include: the electronic components to be processed are original electronic components, placed in a tubular material In the tube 112, the material tube 112 is inserted into a grid base with a plurality of parallel slots 111. The device of the present invention can be inserted into the 20-tube material tube 112 at a time; the grid base is connected to the rail 106 through the slider 105, which is connected to the grid base and can be reciprocated on the support 115 under the drive of the first drive motor 114 Movement, the support 115 is fixedly connected with the automatic glue application module 120. The first driving motor 114 adopts a stepping motor, and drives the grid base and the slider 105 through a timing belt under the control of a control driver.

The position of the clamping station is changed from the first The hydraulic buffer 311 ensures that the first transfer slider 308 slides in the slotted slide of the base 302; similarly, another electronic component is in the second push-pull cylinder 302, the second cylinder top block 305, and the second transfer slider 306, The transmission of the second oil pressure buffer 304 and the third oil pressure buffer 307 is sent down to the corresponding clamping station. Combining the shapes of different electronic components, the shape of the feeding trough and the shape of the gripping part of the present invention can be changed according to actual needs.
