[0029] Referring to Figure 1 , the first embodiment of the flip chip sorting mechanism of the present application is shown, which comprises an ejecting part 1, a first blue film 2 and a BIN island 7.

[0030] The first blue film 2 is arranged on one side of the ejecting end of the ejecting part 1, and a plurality of crystal grains 4 are adhered to the first blue film 2. The BIN island 7 is arranged on the side of the first blue film 2 away from the ejecting part 1, and a second blue film 3 is arranged on the side of the BIN island 7 close to the first blue film 2. The ejecting part 1 is used to eject the crystal grains 4 on the first blue film 2, and the BIN island 7 is moved to eject the second blue film 3 and adhere to the crystal grains 4 on the first blue film 2, so as to adhere the crystal grains 4 on the first blue film 2 to the second blue film 3.

[0031] It can be understood that the first blue film 2 is pierced by the ejecting part 1, and the crystal grains 4 on the first blue film 2 are ejected, so that the crystal grains 4 are no longer adhered to the first blue film 2. At this time, the BIN island 7 is moved to eject the second blue film 3, drive the second blue film 3 to move close to the first blue film 2, and make the second blue film 3 adhere to the ejected crystal grains 4, so as to complete the sorting of the crystal grains 4.

[0032] Specifically, in the present embodiment, the ejecting part 1 is a ejecting pin, and a driving cylinder 11 is connected to the end of the ejecting pin 1 away from the first blue film 2. The output end of the driving cylinder 11 is connected to the ejecting pin, and is used to eject the ejecting pin. The end of the ejecting pin close to the driving cylinder 11 is arranged in a rectangular structure. The ejecting pin is driven by the driving cylinder 11, so that the ejecting pin can pierce the first blue film 2 and eject the crystal grains 4 on the first blue film 2.

[0033] It should be noted that by setting one end of the ejector pin in a rectangular structure, the one end of the ejector pin can better bear the force of the driving cylinder 11, so that the driving cylinder 11 can better drive the ejector pin, and the ejector pin can eject the die 4 adhered to the first blue film 2.

[0034] Further, in the embodiment, the BIN island 7 is provided with a driving part 71 away from one side of the second blue film 3, and the output end of the driving part 71 is connected to one side of the BIN island 7 and used to drive the BIN island 7 to move, so that the BIN island 7 drives the second blue film 3 to adhere to the die 4.

[0035] It should be noted that in the embodiment, the driving part 71 is a cylinder, and in specific implementation, the driving part 71 drives the BIN island 7 to move, so that the BIN island 7 drives the second blue film 3 to move, so that the second blue film 3 can adhere to the die on the suction nozzle 5, and then the sorting of the die 4 is completed.

[0036] Further, the output end of the driving part 71 is connected to the middle of the side wall of the BIN island 7. It can be understood that the output end of the driving part 71 is connected to the middle of the side wall of the BIN island 7, so that the driving part 71 can stably drive the BIN island 7 to move, avoiding the problems of unstable movement and shaking, so that the BIN island 7 can stably drive the second blue film 3 to move.

[0037] In the embodiment, the second blue film 3 is attached to the side wall of the BIN island 7. It can be understood that the second blue film 3 is attached to the surface of the BIN island 7 in a flat manner. After the die 4 is ejected from the surface of the first blue film 2 by the ejecting part 1, the flat second blue film 3 can better adhere to the ejected die 4, so as to complete the sorting of the die.

[0038] It is worth mentioning that the direction of the crystal grain 4 after sorting is opposite to that before sorting, which meets the delivery requirement, eliminates the manual film reversing operation, reduces the labor cost, eliminates the film reversing loss existing in the manual film reversing, reduces the production cost, eliminates the use of additional blue film, release paper, acetone and other materials, reduces the production cost, and also reduces the pollution and scratches existing in the film reversing process. Therefore, the electrode surface of the crystal grain after sorting faces upward, meets the delivery requirement, eliminates the manual film reversing operation, and eliminates the film reversing loss after sorting. At the same time, the consumption of the blue film, release paper, acetone and other materials used in the film reversing operation is eliminated, the pollution and scratches in the film reversing process are avoided, and the product quality is ensured to a certain extent. While meeting the delivery requirement, the step of the manual film reversing is eliminated. Therefore, the consumption of the blue film, release paper, acetone and other materials used in the film reversing operation is eliminated, the contact with the labor is reduced, and the pollution risk and loss of the crystal grain after sorting are reduced. In addition, the action of the suction nozzle for grabbing the crystal grain is eliminated, so that the use of the suction nozzle material is eliminated, and the production cost is further reduced.

[0039] The utility model discloses still propose a flip chip sorting equipment, including above-mentioned flip chip sorting mechanism.

[0040] In conclusion, the flip chip sorting mechanism in the above-mentioned embodiment of the utility model, the crystal grain 4 on the first blue film 2 is ejected through the ejecting part 1, then the BIN island 7 is moved to make the BIN island 7 move the second blue film 3 to the crystal grain 4 adhered and adsorbed, so as to complete the film reversing sorting of the crystal grain 4, without manual film reversing, effectively reduce the labor cost, and avoid scratching the crystal grain and polluting the crystal grain.
