Description

Technical Field

[0001] This utility model relates to the field of silicon wafer cleaning technology, and in particular to a four-stage agitation mechanism. Background Technology

[0002] Debinding of photovoltaic silicon wafers is a crucial step in the silicon wafer manufacturing process, especially after the wire cutting process. The cleanliness of the silicon wafer surface is a key parameter determining the wafer yield and cell conversion efficiency; therefore, the debinding and cleaning step is essential for obtaining high-cleanliness silicon wafers. During silicon wafer debinding, a basket containing the silicon wafers is typically placed in a debinding machine. Physical methods, such as spray cleaning, ultrasonic cleaning, and overflow cleaning, are used to effectively remove impurities such as metal particles, silicon powder, silicon carbide particles, and residual suspensions from the cutting process from the silicon wafer surface.

[0003] Especially during ultrasonic cleaning, the silicon wafer basket containing the wafers needs to be lifted up and down to accelerate the cleaning process and improve cleaning efficiency. Therefore, a throwing device is usually integrated into the debonding machine to drive the silicon wafer basket in this up-and-down motion for better cleaning results. However, the throwing device is prone to positioning deviations during assembly, leading to insufficient installation accuracy. This can affect the stability of the silicon wafer basket's lifting motion, reduce cleaning effectiveness, and in severe cases, even cause the silicon wafer basket to accidentally detach from the throwing device.

[0033] like Figures 1 to 3The diagram shows the preferred embodiment of this utility model. The four-unit throwing mechanism of this embodiment includes a throwing frame 1, a driving component 2, two driven components 3, and a positioning component 4. The throwing frame 1 is used to place the silicon wafer basket; the driving component 2 is used to provide power; the two driven components 3 are arranged in parallel and are respectively connected to both ends of the driving component 2. The throwing frame 1 is mounted on the two driven components 3, and the driving component 2 drives the throwing frame 1 to throw by driving the driven components 3; the positioning component 4 includes a solid shaft core 401 and a hollow steel tube 402. One end of the solid shaft core 401 is sleeved with one end of the hollow steel tube 402, and the other end of the solid shaft core 401 and the other end of the hollow steel tube 402 are respectively connected to a driven component 3. A scale positioning part is formed at the sleeve joint of the solid shaft core 401 and the hollow steel tube 402.

[0034] Therefore: the drive component 2 provides power to drive the driven component 3 to move the throwing frame 1, so that the silicon wafer basket placed on the throwing frame 1 swings up and down with the throwing frame 1, thereby achieving the purpose of washing the surface of the silicon wafer and obtaining a better cleaning effect; and a positioning component 4 is set between the two driven components 3. The positioning component 4 adopts a design of interlocking solid shaft core 401 and hollow steel tube 402, and the interlocking part forms a scale positioning part, so that the assembly personnel can position according to the scale positioning part during installation to ensure installation accuracy.

[0035] In this embodiment, the positioning component 4 further includes a locking part 406, which is disposed at the joint between the hollow steel tube 402 and the solid shaft core 401 and is used to lock the hollow steel tube 402 and the solid shaft core 401 to prevent slippage between them.

[0036] In this embodiment, the drive assembly 2 includes a drive motor 201 and a projectile drive shaft 202. The projectile drive shaft 202 is connected to the output end of the drive motor 201. The projectile drive shaft 202 is arranged along the x-axis. Both ends of the projectile drive shaft 202 are respectively connected to a driven assembly 3 through a transmission assembly 5.

[0037] In this embodiment, each driven component 3 includes a projectile drive shaft 301 and an eccentric cam plate 302. The projectile drive shaft 301 is connected to the projectile drive shaft 202 through a transmission component 5. The projectile drive shaft 301 is arranged along the y-axis. The eccentric cam plate 302 is sleeved on the projectile drive shaft 301. The projectile frame 1 is mounted on the eccentric cam plate 302. The outer side wall of the eccentric cam plate 302 is in contact with the lower end face of the projectile frame 1.

[0038] In this embodiment, the transmission component 5 includes a first bevel gear 501 and a second bevel gear 502 that cooperate with each other. The first bevel gear 501 is sleeved on the ballistic drive shaft 202, and the second bevel gear 502 is sleeved on the ballistic transmission shaft 301.

[0039] In this embodiment, each of the two ends of the ballistic drive shaft 301 is provided with an eccentric cam plate 302.

[0040] In this embodiment, the throwing frame 1 includes:

[0041] Four vertical shafts 101, each extending along the z-axis and mounted on an eccentric cam plate 302;

[0042] Two projectile connecting rods 102 are provided, both of which are arranged along the x-axis, and both ends of each projectile connecting rod 102 are connected to a vertical shaft 101.

[0043] The throwing frame 103 has two ends connected to a throwing connecting rod 102, and is used to place silicon wafer baskets.

[0044] In this embodiment, each vertical shaft 101 includes a vertical shaft structure 104 and a mounting plate structure 105. The upper end of the vertical shaft structure 104 is connected to the projectile connecting rod 102, and the lower end of the vertical shaft structure 104 is connected to the mounting plate structure 105. The lower end face of the mounting plate structure 105 is in contact with the outer wall of the eccentric cam plate 302.

[0045] In this embodiment, the scale positioning part includes a scale line 403 and a positioning indicator line 404. The scale line 403 is disposed on one end of the solid shaft core 401, and an observation hole 405 for exposing the scale line 403 is opened on the side wall of one end of the hollow steel tube 402. The positioning indicator line 404 is disposed on the side wall of one end of the hollow steel tube 402 and is configured to match the scale line 403. Thus, during installation, the assembler can use the scale line 403 and the positioning indicator line 404 to perform positioning based on their interaction, ensuring installation accuracy. It also allows the assembler to check whether the installation of the four-unit throwing mechanism is accurate.

[0046] In this embodiment, both the solid shaft core 401 and the hollow steel tube 402 are arranged along the x-axis. The other end of the solid shaft core 401 is connected to the projectile transmission shaft 301 through a fixed seat, and the other end of the hollow steel tube 402 is also connected to another projectile transmission shaft 301 through a fixed seat.

[0047] The working principle of this embodiment is as follows: The hollow steel pipe 402 and the solid shaft core 401 are adjusted telescopically according to actual needs. Once the positioning indicator line 404 is adjusted to the designated scale line 403, the hollow steel pipe 402 and the solid shaft core 401 are locked together by the locking part 406 to prevent slippage. The drive motor 201 is started, which drives the throwing drive shaft 202 to rotate. Through the meshing transmission of the first bevel gear 501 and the second bevel gear 502, the throwing drive shaft 301 rotates, thereby… The eccentric cam plate 302, which is sleeved on the throwing drive shaft 301, rotates with the throwing drive shaft 301. Utilizing the characteristics of the cam, the continuous rotational motion can be converted into reciprocating linear motion, thereby causing the vertical shaft 101 set on the eccentric cam plate 302 to move back and forth along the z-axis. Ultimately, this drives the throwing connecting rod 102 and the throwing frame 103 to throw up and down along the z-axis, causing the silicon wafer basket placed on the throwing frame 1 to swing up and down with the throwing frame 1, thereby achieving the purpose of rinsing the surface of the silicon wafer and obtaining a better cleaning effect.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.
