Description

Substrate storage device

The present invention relates to a storage device, and more particularly to a substrate storage device that enhances a storage effect by using a blowing unit.

The solar wafer is an important component of the solar cell, and it needs to go through multiple processes, such as diffusion, cleaning, screen printing, etc., and the solar wafer must be stored in the storage box during the process, and the solar wafer is conventionally used by the adsorption device. The solar wafers are adsorbed one by one and placed in the storage box, but in this way, the storage speed is slow and the efficiency is low.

Therefore, it has been developed to use a conveyor belt to arrange the solar wafers on the conveyor belt and then continuously transport them into the storage box. This method greatly increases the storage speed, but this method often causes the solar wafers in the storage box. Due to friction, static electricity and other factors, it is impossible to align and the difference is very large, so it is easy to cause an increase in fragmentation rate and a decrease in yield. Further, the conventional storage device can accommodate only a single-sized substrate, which is extremely inconvenient, and often causes a problem of a blade between the solar wafers during storage. Therefore, the inventors have diligently studied and designed the present invention which can improve the above disadvantages.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a substrate housing apparatus which can more accurately align a substrate during storage to reduce the fragmentation rate and prevent the problem of the blade.

In order to achieve the above object, the present invention provides a substrate storage device for accommodating a plurality of substrates, comprising: a storage unit for accommodating the substrates; and a blowing unit disposed on a side of the storage unit, the blowing The air blowing direction of the air unit faces the storage unit for sending a guiding airflow between the substrates to form an air flow layer when the substrates are received, and a lifting unit, wherein the storage unit is disposed on the lifting unit The storage unit is lowered as the stack height of the substrates is increased.

The invention has the following beneficial effects:

The invention utilizes a blowing unit to generate an air flow layer between each substrate, thereby reducing various resistances between the substrates, such as frictional force, adsorption force caused by static electricity, etc., so that each substrate can reach a predetermined storage position. The substrate can be stored more neatly, thereby reducing the fragmentation rate and preventing the problem of the blade.

The storage box of the present invention adopts a modular design, and the storage box can have various sizes, such as 5 inches or 6 inches. The user can select different sizes of storage boxes according to the size of the substrate to be stored.

Referring to FIG. 1 , FIG. 6 and FIG. 6A , the present invention provides a substrate storage device including a body 1, a lifting unit 2, a connecting unit 3, a storage unit 4, a blowing unit 5, and a conveying device. Unit 6.

The type of the lifting unit 2 is not limited, and only the same function is required, and different mechanisms can be selected according to actual needs.

The connecting unit 3 is mounted on the lifting unit 2, which can be adjusted in height by the lifting unit 2. The connecting unit 3 has a tripod 31 and a support post 32. The tripod 31 is mounted on the lifting unit 2, and one end of the support post 32 is connected to the tripod 31, and the other end is connected to the storage unit 4. In this embodiment, the tripod 31 includes a connecting plate 311, two triangular supporting plates 312 and a substrate 313. The connecting plate 311 is mounted on the lifting unit 2. The two supporting plates 312 are connected to the connecting plate 311 at one side, and the other adjacent side is connected to the substrate 313. The two support plates 312 are parallel and aligned with each other. The substrate 313 is parallel to the horizontal plane and is connected to the support post 32.

Referring to FIGS. 1 , 2 and 5 , the storage unit 4 is connected to the support column 32 of the connection unit 3 . The storage unit 4 in the present embodiment is disposed in the elevation unit 2 through the connection unit 3, but the storage unit 4 may be directly disposed in the elevation unit 2. The storage unit 4 has a base 41 and a storage box 42 , and the storage box 42 is detachably provided to the base 41 . The base 41 has an inclination angle θ with the horizontal plane, and the base 41 has a catching portion 412. In this embodiment, the inclination angle θ between the base 41 and the horizontal plane is 10° to 20°. The shape of the storage case 42 is not limited and may be appropriately changed, such as a quadrangle, a hexagon, an octagon or a circle.

The storage box 42 has a base portion 421 and at least one stopper portion 422. The at least one stop portion 422 is coupled to the edge of the base portion 421. The at least one stop portion 422 is perpendicular to the base portion 421. The base portion 421 of the storage box 42 is engaged with the engaging portion 412 of the base 41. The edge of the storage box 42 has at least one notch 423, which can facilitate the removal of the substrate after the storage. The at least one blocking portion 422 of the storage box 42 has a cushion 424 inside, and the cushion 424 is connected to the at least one stopping portion 422. The cushion pad 424 can prevent the substrate (not shown) from colliding with the stopper portion 422 during storage, thereby reducing the chipping rate. In this embodiment, the cushion 424 is a foam pad, but is not limited.

Referring to FIGS. 1 , 6 , and 6A , the air blowing unit 5 is disposed on one side of the storage unit 4 . In the present embodiment, the air blowing unit 5 is fixed to the top of the lifting unit 2, but it is not limited, and may be appropriately changed according to actual conditions. For example, the air blowing unit 5 may be fixed to the body 1, the connecting unit 3, or the storage unit 4, and the like. The blowing direction of the blowing unit 5 faces the storage box 42, and the blowing unit 5 is connected to an appropriate air supply device (not shown), and the guiding airflow can be sent to the storage box 42 without stopping (not shown). In the present embodiment, the air blowing unit 5 has a hollow casing 51. The hollow casing 51 has at least one air inlet hole 53. The hollow casing 51 has a plurality of air outlet holes 52 on one side of the storage box 42 to inject gas from the air inlet hole 53 into the hollow casing 51. The gas is sent out from the air outlet 52.

The transport unit 6 is disposed in the body 1 and has a transport direction toward the storage unit 4 for transporting the substrate (not shown) into the storage case 42 of the storage unit 4. The conveying unit 6 is higher than the blowing unit 5. The conveying unit 6 in this embodiment is a conveyor belt, but is not limited, and a different conveying mechanism can be selected.

The operation mode and principle of the present invention are as follows:

First, the air blowing unit 5 is turned on to continuously supply the guiding airflow to the storage box 42. Next, the transport unit 6 is turned on to continuously transport the substrate to the storage case 42.

During the storage process, each of the substrates immediately enters the storage box 42 due to the airflow sent by the air blowing unit 5, so that an air flow layer is formed between the substrate and the substrate in the storage box 42 (not shown). The substrate is slid into the storage case 42 in the direction in which the base 41 is inclined, and reaches the predetermined storage position until the top abuts against the stopper portion 422.

The airflow layer allows the substrate to remain in a semi-floating state before reaching the predetermined storage position, thereby reducing the resistance between the substrates, such as the frictional force or the electrostatic adsorption force, so that each substrate can reach the predetermined storage position. The substrate can be stored more neatly, thereby reducing the fragmentation rate and preventing the problem of the blade.

As the substrate is continuously accumulated to increase its thickness, the storage unit 4 is lowered by the lifting unit 2, so that the air outlet 52 of the air blowing unit 5 is maintained at a relative height facing the surface substrate in the storage case 42.

The storage box 42 of the present invention adopts a modular design. As shown in FIGS. 3 and 4, the storage box 42 can have various sizes, such as 5 inches or 6 inches. The user can select the storage box 42 of different sizes according to the size of the substrate to be stored.
