Detailed Description
Examples
As shown in fig. 1 to 5, the apparatus for removing foreign matters from parts in an injection molding process of the present embodiment includes a support plate 10 vertically disposed, a connecting member 11 disposed on one side of the support plate 10, a plurality of suction devices disposed on the other side of the support plate 10, and a negative pressure device; the connecting piece 11 is used for connecting the mechanical arm; the adsorption device comprises an isolation frame 21 attached to the support plate 10, a discharge port 22 arranged on the lower side wall of the isolation frame 21, a storage box 23 attached to the lower outer side wall of the isolation frame 21, and a feed port 24 arranged at the upper end of the storage box 23; the discharge opening 22 is communicated with the feed opening 24; the negative pressure device comprises a vacuum generator and a negative pressure pipe 30 which is connected with the vacuum generator and is arranged on one surface of the support plate 10 close to the connecting piece 11; the end of the negative pressure tube 30 far away from the vacuum generator is arranged in the isolation frame 21 after passing through the support plate 10.
Specifically, the general operation principle is as follows: connect the backup pad 10 with the arm through connecting piece 11 before using earlier, make the backup pad 10 can move along level and vertical direction, accomplish the injection of work piece when the injection molding machine, push out the back with the work piece, arm drive backup pad 10 is close to the work piece, make the work piece be located inside isolation frame 21, then start vacuum generator, make vacuum generator breathe in through negative pressure tube 30, inhale away the foreign matter such as cilia on work piece surface through negative pressure tube 30, vacuum generator stop work after having inhaled, still have partial foreign matter this moment because can't be fully inhaled in negative pressure tube 30, and then stop in isolation frame 21, this partial foreign matter then can directly fall isolation frame 21 downside, enter into storage tank 23 through bin outlet 22 and feed inlet 24 and collect, prevent that a large amount of foreign matters from piling up in isolation frame 21.
Therefore, the device can directly clean the foreign matters on the surface of the part after the part is formed, thereby not only improving the quality of the finished product and reducing the subsequent operation, but also completing the operation process in a full-automatic way and reducing the manual intervention.
The isolation frame 21 in the embodiment is internally provided with a plurality of suction nozzles 12, and the suction nozzles 12 are connected with a negative pressure machine; the suction nozzle 12 is used for sucking parts. Specifically, negative pressure can be generated at the end part of the suction nozzle 12 through the negative pressure machine, so that the workpiece is sucked, and the workpiece is prevented from falling off in the foreign matter removing process. Wherein the workpiece is clamped simultaneously by the injection molding machine and the suction nozzle 12.
A pair of negative pressure pipes 30 are arranged in an isolation frame 21 in the embodiment; the pair of negative pressure pipes 30 are provided on opposite sides of the partition frame 21. Specifically, the action range of the negative pressure is wider, and the foreign matters can be sucked more effectively.
The adsorption device in the embodiment further comprises a baffle 25 arranged at the feed port 24, and an elastic member 26 for supporting the baffle 25; one side of the baffle 25 is hinged with one side of the feed port 24 close to the support plate 10; one end of the elastic element 26 is connected with the lower side of the baffle 25, and the other end is fixedly connected with the inner side wall of the storage box 23.
