[0066] As described in the background section, please refer to... Figure 1 The ball brush includes a bristle implantation surface 10 for implanting bristles. The bristle implantation surface 10 includes a ball outlet 102 located at the center of the bristle implantation surface 10 for discharging solder balls, and multiple rings of ball implantation holes 104 radiating from the ball outlet 102 to the edge of the bristle implantation surface 10. The multiple ball implantation holes 104 in each ring are spaced apart from each other. The ball brush includes multiple outer ring bristles 110 and multiple inner ring bristles 112. A single outer ring bristle 110 extends from a ball implantation hole 104 in a certain ring of ball implantation holes 104 to the ball implantation hole 104 in that ring. In one of the ball-planting holes 104 of the outer ring of ball-planting holes 104, the remaining outer ring bristles 110 are sequentially braided along the braiding direction of the previous outer ring bristle 110. The single inner ring bristle 112 extends from one of the ball-planting holes 104 in the ring of ball-planting holes 104 near the ball outlet 102 to one of the ball-planting holes 104 in the ring of ball-planting holes 104 located in the area of ​​the outer ring bristles 110. The extension directions of the single outer ring bristles 110 and the single inner ring bristles 112 intersect with the radial direction of the ball-planting surface 10.

[0067] During the wafer ball placement process, a large number of solder balls are exported from the ball outlet 102 of the ball placement surface 10. The ball brush sweeps the surface to be placed along the ball placement direction to fill the corresponding area with solder balls and remove excess solder balls. The bristles are used to confine the solder balls within the area of ​​the bristles to prevent the solder balls from leaking out. However, since the bristles of the ball brush are woven in a specific direction, the solder balls are easily wrapped by the bristles.

[0068] Existing technologies often employ manual air guns to remove solder balls from the ball brush. However, controlling the air volume and direction of the airflow is difficult, easily causing the brush bristles to scatter and deform, leading to abnormal wafer ball placement and reduced brush life. Therefore, there is an urgent need for a cleaning device that can remove solder balls from the ball brush without damaging it.

[0069] For the reasons mentioned above, please refer toFigure 2 This application provides a ball brush cleaning device, which includes: a housing 202, a rotating fixing assembly 204, an air passage 208, an outer ring nozzle 210, and an inner ring nozzle 212; wherein, the housing 202 has a cleaning chamber inside; the rotating fixing assembly 204 is located on the upper side of the cleaning chamber and is used to fix the ball brush 206 and drive the ball brush 206 to rotate; the side of the ball brush 206 opposite to the bristle surface is connected to the rotating fixing assembly 204, and the bristle surface faces the bottom of the cleaning chamber; The rotation direction of the rotating fixing component 204 is related to the preset direction of the bristles in the ball brush; the air passage 208 penetrates the side wall of the housing 202 and extends horizontally from the side wall of the housing 202 to the bottom of the ball brush 206; the inner ring nozzle 212 is connected to the air passage 208 and is located below the inner ring bristles in the ball brush 206, with the inner ring nozzle 212 facing the inner ring bristles; the outer ring nozzle 210 is connected to the air passage and is located below the outer ring bristles in the ball brush 206, with the outer ring nozzle 210 facing the outer ring bristles.

[0070] As an example, the shape of the housing 202 and the cleaning chamber may include a rectangle or other regular or irregular shapes, and is not limited to the shape in this embodiment.

[0071] Please continue to refer to this. Figure 1 and Figure 2 The connection point between the rotating fixing component 204 and the ball brush 206 is located at the center point of the side opposite to the surface where the bristles are located, allowing the ball brush 206 to rotate around the center point. The rotation direction of the rotating fixing component 204 may include clockwise rotation or counterclockwise rotation. The preset direction for the bristles in the ball brush 206 is that a single bristle extends from the ball-planting hole 104 near the ball outlet 102 to the ball-planting hole 104 away from the ball outlet 102. The preset direction may include clockwise or counterclockwise. The rotation direction of the rotating fixing component 204 is the same as the preset direction for the bristles in the ball brush 206, thereby preventing the bristles from being blown apart.

[0072] As an example, the airway 208 is used to guide gas. The airway 208 can be made of metal materials such as iron, copper, and stainless steel, or high molecular polymer materials such as polypropylene and rigid polyvinyl chloride. The material of the airway 208 must be able to ensure the strength of the airway 208 and its corrosion resistance, and can be designed according to the actual cleaning chamber environment.

[0073] In the above embodiments, the ball brush cleaning device includes a housing, a rotating fixing assembly, an air duct, an outer ring nozzle, and an inner ring nozzle. The housing has a cleaning chamber to provide a stable cleaning environment for cleaning the ball brush. The rotating fixing assembly drives the ball brush to rotate, ensuring that the bristles in each area of ​​the ball brush are cleaned. The rotation direction of the rotating fixing assembly is related to the preset direction of the woven bristles in the ball brush, thereby avoiding incorrect air blowing direction during the blowing process, which could cause the bristles to be blown away or disordered. The air duct penetrates the side wall of the housing and extends horizontally from the side wall of the housing to the bottom of the ball brush. The inner ring nozzle and the outer ring nozzle are connected to the air duct, thereby blowing the inner ring bristles and the outer ring bristles separately, improving the accuracy of cleaning the bristles in different areas.

[0074] Please refer to Figure 3 In some embodiments, the rotating fixing assembly includes a rotary motor 302 and a fixing member 306; wherein the rotary motor 302 is located at the top of the housing 202, and the rotating shaft 304 of the rotary motor 302 passes through the outer wall of the top of the housing 202 and extends into the cleaning chamber; the fixing member 306 is connected to the rotating shaft 304 of the rotary motor 302 and the ball brush 206 respectively, and is used to fix the ball brush 206.

[0075] As an example, the cleaning chamber inside the housing 202 may also include a cleaning working chamber (not shown) and a cleaning closed chamber (not shown). The cleaning working chamber and the cleaning closed chamber are separated by a partition (not shown). The cleaning closed chamber is located on the upper side of the cleaning chamber, and the cleaning working chamber is located on the lower middle side of the cleaning chamber. The rotating shaft 304 of the rotary motor 302 and some of the fixing parts 306 may be located in the cleaning closed chamber to avoid the solder balls, dust and other impurities during the cleaning process from affecting the rotation of the rotating shaft 304. In addition, some of the fixing parts 306 may be located in the cleaning working chamber to fix the ball brush 206.

[0076] In some embodiments, the fasteners include: pin fasteners, snap fasteners, hook lock fasteners, etc.

[0077] As an example, the pin fastener may include a U-shaped lug, which may include a pin hole. The side of the ball brush used for connecting with the fastener has a pin hole, and the connection is achieved by passing a pin through the pin hole. The end of the pin is protected from falling off with a cotter pin or a snap ring.

[0078] As an example, the snap fastener may include an annular groove, and the top of the ball brush has a resilient snap, such as a plastic snap or a spring steel snap, which is locked in place by elastic force after being inserted into the annular groove.

[0079] As an example, the hook lock fastener is a hook with a locking buckle, and the top side wall of the ball brush has a hanging ring. After the hook is hooked into the hanging ring, the locking buckle is locked to prevent it from falling off.

[0080] As an example, the surface of the fastener used to connect with the ball brush also has a locating pin to define the position of the ball brush.

[0081] In some embodiments, the ball brush cleaning device further includes: a displacement component located on the side wall of the housing and connected to the air passage, for driving the air passage to move in a vertical direction.

[0082] As an example, the displacement assembly may include a lead screw, a nut, and a drive motor. The lead screw is located on the outer wall of the housing and extends in the vertical direction. The nut is connected to the air passage. When the drive motor drives the lead screw to rotate, the nut moves along the lead screw axis, causing the air passage to move in the vertical direction. The drive motor may be fixed to the housing.

[0083] In the above embodiments, by moving the air passage vertically using the displacement component, the distance between the outer ring nozzle, the inner ring nozzle and the brush bristles can be controlled, thereby controlling the blowing range and blowing force of the airflow and improving the accuracy of ball brush cleaning.

[0084] In some embodiments, please refer to Figure 3 The displacement assembly includes a guide rail 216 and a slider 214. The guide rail 216 is located on the outer wall of the housing 202 and extends in the vertical direction. The slider 214 is located inside the guide rail 216 and is slidably connected to the guide rail 216. The slider 214 is connected to the air passage 208.

[0085] As an example, the air passage 208 can be connected to one side wall of the slider 214, so that the slider 214 can drive the air passage 208 to move in the vertical direction.

[0086] In some embodiments, the ball brush cleaning device further includes a receiving component located at the bottom of the cleaning chamber.

[0087] As an example, the storage components may include a flat-bottomed tray, a collection box, etc., with the flat-bottomed tray or collection box located at the bottom of the cleaning chamber and the side walls of the flat-bottomed tray or collection box adjacent to the bottom side wall of the cleaning chamber.

[0088] In some embodiments, please refer to Figure 3 The storage assembly includes a funnel 218 and a storage container 220. The funnel 218 is located in the cleaning chamber below the air passage 208, with the funnel opening facing the ball brush 206 and the funnel wall of the funnel 218 in contact with the side wall of the housing 202. The storage container 220 is located below the funnel 218, with the funnel outlet of the funnel 218 located inside the storage container 220.

[0089] As an example, the funnel wall of funnel 218 can be a perforated filter screen with a pore size smaller than that of the solder ball. A negative pressure pipe is connected below the perforated filter screen to provide a slight negative pressure, which adsorbs the solder ball into the funnel 218, avoiding airflow interference in the cleaning chamber and preventing the solder ball from scattering.

[0090] As an example, the bottom of the cleaning chamber may also include a rotating carrier (not shown), with the collection bucket 220 located on the rotating carrier. During the process of collecting solder balls, the rotating carrier can drive the collection bucket 220 to rotate, thereby preventing the solder balls from accumulating too high in a localized area within the collection bucket 220.

[0091] In some embodiments, the nozzle includes an inner ring nozzle and an outer ring nozzle; the shape of the nozzle may include a cone shape, with the cone apex serving as the nozzle's air outlet, thereby preventing solder balls from getting stuck on the nozzle or between the nozzle and the air passage.

[0092] In some embodiments, the nozzle includes an inner ring nozzle and an outer ring nozzle; the nozzle also includes a mesh covering the air outlet of the nozzle.

[0093] As an example, the mesh size is smaller than the solder ball size to prevent solder balls from falling into the nozzle and causing nozzle blockage. In addition, the mesh may have arc-shaped protrusions to prevent solder balls from accumulating on the mesh.

[0094] In some embodiments, the ball brush cleaning device further includes an air valve, which is connected to the inner ring nozzle and the outer ring nozzle respectively, for controlling the air flow of the inner ring nozzle and the outer ring nozzle.

[0095] In the above embodiment, by connecting the air valve to the inner ring nozzle and the outer ring nozzle respectively, the air flow of the inner ring nozzle and the outer ring nozzle is controlled, thereby controlling the blowing force of the airflow on the bristles and avoiding blowing the bristles into a mess.

[0096] In summary, the ball brush cleaning device of this application includes a housing, a rotating and fixing assembly, an air duct, an outer ring nozzle, and an inner ring nozzle. The housing has a cleaning chamber to provide a stable cleaning environment for cleaning the ball brush. The rotating and fixing assembly drives the ball brush to rotate, ensuring that the bristles in each area of ​​the ball brush are cleaned. The rotation direction of the rotating and fixing assembly is related to the preset direction of the bristles in the ball brush, thereby avoiding incorrect air blowing direction during the blowing process, which could cause the bristles to be blown away or disordered. The air duct penetrates the side wall of the housing and extends horizontally from the side wall of the housing to the bottom of the ball brush. The inner ring nozzle and the outer ring nozzle are connected to the air duct, thereby blowing the inner ring bristles and the outer ring bristles separately, improving the accuracy of cleaning the bristles in different areas.

[0097] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
