DETAILED DESCRIPTION

[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] like Figure 1 As shown, an embodiment of the present invention provides a wafer 7 packaging device, including a crane fixing area 1, a wafer loading area 2 and a wafer packaging area 3. The wafer loading area 2 and the wafer packaging area 3 are located below the crane fixing area 1. A crane transport device 4 is provided in the crane fixing area 1. The crane transport device 4 includes a horizontal component 10, a vertical component 20, a clamping component 30, a first dustproof plate 40 and a second dustproof plate 50. Figure 2 As shown. The horizontal component 10 of the traveling crane transporting device 4 is fixedly set in the traveling crane fixed area 1, and the vertical component 20 of the traveling crane transporting device 4 extends out from the traveling crane fixed area 1 and can drive the clamping component 30 to move back and forth along the horizontal direction D1 between the wafer loading area 2 and the wafer packaging area 3 through the horizontal component 10. By setting the traveling crane transporting device 4 in the traveling crane fixed area 1 in the upper area of ​​the wafer 7 packaging equipment, the horizontal component 10 of the traveling crane transporting device 4 is located above the wafer loading area 2 and the wafer packaging area 3, and the vertical component 20 can move back and forth between the wafer loading area 2 and the wafer packaging area 3. In conjunction with the first dustproof plate 40 and the second dustproof plate 50, dust, impurities and other pollutants can be isolated outside the wafer loading area 2 and the wafer packaging area 3, preventing the wafer 7 from being contaminated during the packaging process and affecting the packaging effect of the wafer 7.

[0030] See also Figure 2 、 Figure 3 and Figure 4In the traveling transport device 4 of the present embodiment, the horizontal component 10 extends along the horizontal direction D1 and has a first side 11 and a second side 12 opposite to each other in the front-to-back direction D3. The vertical component 20 extends along the vertical direction D2 and has a top 21 and a bottom 22 in the vertical direction D2. The horizontal direction D1, the vertical direction D2 and the front-to-back direction D3 are perpendicular to each other. The top 21 of the vertical component 20 is movably connected to the horizontal component 10. The clamping component 30 is movably connected to the bottom 22 of the vertical component 20. The clamping component 30 is moved in the vertical direction D2 and the horizontal direction D1 through the vertical component 20 and the horizontal component 10. The clamping component 30 can be used to clamp and transport the basket 5. The basket 6 is placed in the basket 5, and the basket 6 is loaded with wafers 7. When the wafer 7 packaging equipment starts working, the clamping component 30 is at the bottom 22 of the vertical component 20. The components 20 and the horizontal component 10 are moved to the wafer cargo area 2 to prepare for transporting the basket 5. After the clamping component 30 moves into place, the clamping basket 5 begins to be transported. The position is adjusted in the vertical direction D2 by the vertical component 20, so that the basket 5 is in place in the vertical direction D2 before entering the wafer packaging area 3. Then the position is adjusted in the horizontal direction D1 by the horizontal component 10, so that the basket 5 enters the wafer packaging area 3 to perform the corresponding process, and the clamping component 30 can also fine-tune the position of the basket 5 in the front-to-back direction D3 perpendicular to the vertical direction D2 and the horizontal direction D1. Through the above-mentioned movement method, the vertical component 20, the horizontal component 10 and the clamping component 30 jointly realize the movement of the basket 5 in the three degrees of freedom of the vertical direction D2, the horizontal direction D1 and the front-to-back direction D3, which can basically meet the requirements of the wafer 7 being able to move to various areas in the wafer 7 packaging equipment. The first dustproof plate 40 is fixedly provided on the horizontal component 10 and is located on the first side 11, and the second dustproof plate 50 is fixedly provided on the horizontal component 10 and is located on the second side 12. There is a first height difference H1 between the first dustproof plate 40 and the second dustproof plate 50 in the vertical direction D2, and the top 21 of the vertical component 20 extends into the first height difference H1. By arranging the first dustproof plate 40 and the second dustproof plate 50 up and down and being arranged on both sides of the horizontal component 10, all dust, impurities and other pollutants above the horizontal component 10 can be isolated to prevent them from invading the wafer cargo area 2 and the wafer packaging area 3, and will not affect the movement of the vertical component 20 on the horizontal component 10. The top 21 of the vertical component 20 is extended into and fills the space of the first height difference H1, which makes full use of the thickness of the horizontal component 10 in the vertical direction D2 and saves space in the wafer 7 packaging equipment.The top 21 of the vertical component 20 is movably connected to the second side 12, the second dustproof plate 50 is higher than the first dustproof plate 40 in the vertical direction D2, the vertical component 20 is located below the second dustproof plate 50, and the gap between the top 21 of the vertical component 20 and the second dustproof plate 50 is matched, which neither affects the movement of the vertical component 20 on the horizontal component 10, nor avoids the friction between the vertical component 20 and the second dustproof plate 50 during movement to generate contaminants that invade the wafer packaging area 3 below and contaminate the wafer 7 and equipment.

[0031] See also Figure 5 and Figure 6 The first dustproof plate 40 has an air intake portion 41, a ventilation portion 42 and an exhaust portion 43. The exhaust portion 43 is fixed on the horizontal component 10. The air intake portion 41 and the exhaust portion 43 are connected through the ventilation portion 42. After entering from the air intake portion 41, the air flows into the exhaust portion 43 through the ventilation portion 42 and is finally discharged from the exhaust portion 43. The air duct through the air intake portion 41, the ventilation portion 42 and the exhaust portion 43 can achieve the dustproof function without affecting the air circulation performance inside the wafer 7 packaging equipment.

[0032] In the first dustproof plate 40, the air inlet portion 41 and the air vent portion 42 are open at the top ends in the vertical direction D2. Figure 5 As shown, the air flow area of ​​the air in the air inlet 41 and the vent 42 can be significantly larger than the air flow area of ​​the air in the exhaust 43, so that the air flow rate can be significantly accelerated after entering the exhaust 43, thereby facilitating air circulation. The air inlet 41 has an air inlet 60, which is opened on the side of the air inlet 41 away from the exhaust 43. Figure 3 、 Figure 5 and Figure 6 A second height difference H2 is formed between the first bottom surface 44 of the air inlet portion 41 and the second bottom surface 45 of the air outlet portion 43 in the vertical direction D2, and the first bottom surface 44 is higher than the second bottom surface 45. The air vent portion 42 has an inclined bottom surface 46, which connects the first bottom surface 44 and the second bottom surface 45 and is used to guide air from the air inlet portion 41 to the air vent portion 42 and then to the air outlet portion 43. Figure 4 and Figure 6 The second bottom surface 45 of the exhaust portion 43 is provided with exhaust holes 47, through which air is discharged. Dust, impurities and other pollutants of a certain size can be isolated through the exhaust holes 47. There are multiple exhaust holes 47, which are arranged in rows, columns or a matrix on the second bottom surface 45. This can further increase the size of pollutants that can be isolated without affecting the ventilation performance. Figure 3 and Figure 5The exhaust portion 43 has a first connection portion 48 and a second connection portion 49. The first connection portion 48 extends from the second top surface of the exhaust portion 43 to the first side 11 and is connected to the horizontal component 10 on the first side 11. The second connection portion 49 extends from the second top surface to the second side 12 and is connected to the horizontal component 10 on the second side 12. An avoidance gap 70 is formed between the first connection portion 48 and the second connection portion 49. The avoidance gap 70 is located below the horizontal component 10. This structural design can not only save space inside the equipment in the front-to-back direction D3, but also prevent dust, impurities and other pollutants generated by the horizontal component 10 during operation from falling into the wafer cargo area 2 and the wafer packaging area 3 through the avoidance gap 70, thereby effectively isolating pollutants and further ensuring the cleanliness of the inside of the wafer 7 packaging equipment.

[0033] The crane handling device and wafer packaging equipment disclosed in the present invention can prevent dust, impurities and other pollutants from falling from the upper area of ​​the equipment into the lower area and invading the packaging area of ​​the packaged wafers during the wafer handling process, thereby ensuring that the wafers are not contaminated during the packaging process and the interior of the wafer packaging equipment is clean.

[0034] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. However, the present invention is not limited to the above-described specific embodiments.
