[0043] The utility model provides a chip loading and unloading machine through improvement. The technical solution of the utility model is:

[0044] like Figure 1 As shown,

[0045] A chip loading and unloading machine comprises a frame 1, and also comprises a loading mechanism 2, a first unloading mechanism 3, a second unloading mechanism 4, a material moving mechanism 5 and a visual positioning mechanism arranged on the frame 1.

[0046] like Figure 3As shown, the first unloading mechanism 3 includes a first transport line 31, a first silo 32 and a first lifting assembly 33. A first pull-out assembly 34 is arranged in the middle of the first transport line 31, and a plurality of fixture trays 321 are arranged in the first silo 32. The first pull-out assembly 34 is used to pull out the fixture trays 321, and the first lifting assembly 33 drives the first silo 32 to rise and fall. The first transport line 31 is used to move the pulled fixture tray 321 to the bottom of the material transfer mechanism 5, waiting for the material transfer mechanism 5 to absorb or put in the chip. The first transport line 31 is used to support the fixture tray 321.

[0047] like Figure 4 As shown, the second unloading mechanism 4 includes a second transport line 41, a second material bin 42, and a second lifting assembly 43. A second pull-out assembly 44 is arranged in the middle of the second transport line 41, and a plurality of material trays 421 are arranged in the second material bin 42. The second pull-out assembly 44 is used to pull out the material trays 421, and the second lifting assembly 43 drives the second material bin 42 to rise and fall. The second transport line 41 is used to move the pulled-out material trays 421 to the bottom of the material transfer mechanism 5, waiting for the material transfer mechanism 5 to put in the chips. The second transport line 41 is used to support the material trays 421.

[0048] like Figure 8 As shown, the material transfer mechanism 5 includes a first translation assembly 51, a second translation assembly 52, a third lifting assembly 53, a first rotating device 54 and a suction head 55 which are sequentially connected in transmission.

[0049] When in use, the material transfer mechanism 5 first moves to the top of the loading mechanism 2 to absorb the chip; at the same time, the first pull-out assembly 34 pulls out the fixture tray 321, and the first conveyor line moves the fixture tray 321 to the bottom of the material transfer mechanism 5; then the material transfer mechanism 5 moves to place the chip on the suction head 55 into the fixture tray 321. After one tray is placed, the first conveyor line cooperates with the first pull-out assembly 34 to put the fixture tray 321 back into the first bin 32, and the first bin 32 rises or falls, so that the first pull-out assembly 34 can pull out the next tray of fixture trays 321.

[0050] After the jig tray 321 is placed, the jig tray 321 is taken out manually or by an external machine for inspection. After the inspection, the jig tray 321 after inspection and sorting is placed back into the first material bin 32. Then the material transfer mechanism 5 sucks up the chips on the jig tray 321, and at the same time the second pull-out assembly 44 pulls out the material tray 421, and the second conveyor line moves the material tray 421 to the bottom of the material transfer mechanism 5. Then the material transfer mechanism 5 moves to place the chips on the suction head 55 into the material tray 421. After a tray of material trays 421 is placed, the second conveyor line cooperates with the second pull-out assembly 44 to put the material tray 421 back into the second material bin 42, and the second material bin 42 rises or falls, so that the second pull-out assembly 44 can pull out the next tray of material trays 421. In this way, the automatic loading and unloading of chips can be realized.

When in use, first put the roll with the chip on the feeding roll 21, then manually tear off a section of the upper film, wrap the upper film around the upper film roll 23, and wrap the bottom film around the bottom film roll 24, and then the automatic film tearing and feeding operation can be performed. The film tearing station 22 is provided with a film feeding roll 27, and the film feeding roll 27 is connected to a fourth rotating device 28 by transmission. The film feeding roll 27 is used to make the film tearing smoother and less prone to jamming.
