Description

Technical Field

[0001] The utility model relates to the technical field of crystal plate processing and transporting devices, and in particular to a suction nozzle replacement device. Background Art

[0002] During the processing of chips, they need to be transferred between different workstations. Generally, a chip suction device is used to suck the chips and transfer them to the next position. The chip suction device is equipped with a suction nozzle, which can absorb the chip when it touches the chip downward. When the suction nozzle reaches the end of its service life, it needs to be replaced with a new one; when encountering chips of different specifications, it is necessary to replace the suction nozzle of different specifications.

[0003] When replacing the nozzle of the chip suction device, the original nozzle needs to be unplugged and another nozzle needs to be plugged into the chip suction device. At present, the common nozzle replacement method is to manually or use a clamp to hold the nozzle, unplug the old nozzle from the suction device, and then plug another nozzle into the suction device. Since the nozzle needs to be put down and picked up in the middle, the nozzle replacement efficiency is low and the operation is inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to save the action of putting down and picking up the suction nozzle in the middle and improve the efficiency of replacing the suction nozzle.

During installation, the fixing seat 1 can be fixed on the workbench of the production line. The working process is as follows Figure 3 As shown:

[0038] The steps of pulling out the suction nozzle 21 from the chip suction device 20 are as follows: the suction nozzle 21 on the chip suction device 20 first moves to the top of the vacated suction nozzle socket; the horizontal motion mechanism drives the card plate 4 to move horizontally backward so that the large end of the gourd hole 41 faces the suction nozzle socket; the driving member drives the bracket 2 to move upward so that the suction nozzle 21 on the chip suction device 20 is inserted into the large end of the gourd hole 41 and the suction nozzle socket; the horizontal motion mechanism drives the card plate 4 to move horizontally forward so that the small end of the gourd hole 41 faces the suction nozzle socket, thereby clamping the suction nozzle 21 in the suction nozzle socket; the driving member drives the bracket 2 to move downward to pull the suction nozzle 21 out of the chip suction device 20.

[0039] The steps for installing the suction nozzle 21 are as follows: the suction nozzle plug interface of the chip suction device 20 moves to the top of the suction nozzle 21 to be installed; the driving member drives the bracket 2 to move upward, so that the suction nozzle 21 is plugged into the suction nozzle plug interface of the chip suction device 20; the horizontal movement mechanism drives the clamping plate 4 to move horizontally backward, so that the large end of the gourd hole 41 is opposite to the suction nozzle plug hole, and the suction nozzle 21 is contacted and clamped; the driving member drives the bracket 2 to move downward, so that the suction nozzle 21 is separated from the large end of the gourd hole 41 and the suction nozzle plug hole, and the installation is completed; the horizontal movement mechanism drives the clamping plate 4 to move horizontally forward, so that the small end of the gourd hole 41 is opposite to the suction nozzle plug hole, thereby keeping the remaining suction nozzle 21 clamped in the suction nozzle plug hole.

[0040] Note: The lower diameter of the nozzle 21 is larger than the middle and upper diameter, so that it can be clamped by the small end of the gourd hole 41. The structure of the nozzle 21 is the prior art. The chip suction device 20 is the prior art, and is provided with a nozzle plug interface for plugging the nozzle 21.

[0041] By adopting the utility model, the nozzle seat 3 can pre-install multiple nozzles 21, eliminating the picking and placing action during the replacement of the nozzle 21, and improving the replacement efficiency; the horizontal movement of the clamping plate 4 is coordinated with the vertical movement of the bracket 2, so that the replacement process of the nozzle 21 is convenient to automatically control, the movement is stable, and the installation is convenient; when the nozzle 21 is replaced, the calabash hole 41 is driven by the clamping plate 4 to move horizontally, so as to clamp or release the nozzle 21, and the operation is convenient; when the small end of the calabash hole 41 moves to the nozzle plug hole, the nozzle 21 can be clamped, and the nozzle 21 can be easily pulled out from the equipment; when the large end of the calabash hole 41 moves to the nozzle plug hole, it is convenient for the nozzle 21 to enter and exit the nozzle plug hole.
