Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, for the structure schematic diagram of the cleaning machine for electroplated copper balls under an embodiment of the present invention, the cleaning machine for electroplated copper balls 1 includes a feeding device 11 and a cleaning device 12, the feeding device 11 includes a feeding screen 111 having a plurality of screen holes 112, wherein the size of the screen holes 112 can be determined according to the minimum radius (e.g. 5 mm) of the required or available copper balls, so that the feeding screen 111 can screen out all or part of the copper balls which are not in accordance with the required or available requirement during the feeding process, thereby making all or most of the copper balls which enter the cleaning device 12 for cleaning meet the requirement.

The cleaning device 12 is configured to receive the copper balls screened by the feeding screen 111, and may include a cleaning tank 121, a drum 122 having a multi-pass cylinder, a filter tank 123, and a fixing bracket (not shown), where the fixing bracket is configured to fix the filter tank 123, so that at least a part of a tank body of the filter tank 123 is suspended in the cylinder of the drum 122.

The cleaning tank 121 is used for containing a cleaning liquid (such as a chemical solution containing 5% sulfuric acid) for cleaning copper balls, and the drum 122 is rotatably disposed above the cleaning tank 121 and partially disposed in the cleaning tank 121, so that when the cleaning liquid is contained in the cleaning tank 121 and reaches a certain liquid level, the drum 122 and the copper balls located in the drum 122 can be immersed in the cleaning liquid, thereby cleaning the copper balls. It can be understood that, the roller 122 may be specifically configured by disposing a shaft rod inside the cylinder, which coincides with the axis of the cylinder, and the shaft rod may be kept relatively fixed with the cylinder through spokes extending in the radial direction, so that when the driving motor drives the shaft rod to rotate, the shaft rod can drive the roller 122 to rotate above the cleaning tank 121; of course, the drum 122 may also provide a supporting force and/or a power for the drum 122 to rotate above the cleaning tank 121 by providing a roller or the like in the cleaning tank 121 to rotatably cooperate with the outside of the drum body of the drum 122.

The drum 122 includes a first end portion and a second end portion opposite to the first end portion, wherein the first end portion is an end close to the feeding screen 111, and the second end portion is an end far from the feeding screen 111. The opening on one side of the first end portion supplies copper balls to the barrel of the roller 122, and at least one row of inverted teeth 124 arranged from the first end portion to the second end portion is arranged on the inner wall of the roller 122, and the inverted teeth 124 are used for supplying the copper balls to roll to the lower position of the roller 122 when the roller 122 rotates in the first rotation direction and for hooking the copper balls to a preset height and then pouring the copper balls out when the roller 122 rotates in the second rotation direction. Wherein the first rotational direction may be a counterclockwise rotation of the drum 122 as viewed in the first end direction, and correspondingly, the second rotational direction is a clockwise rotation of the drum 122.

Here, the lower position of the drum 122 may be understood as the shortest distance between the drum body of the drum 122 and the tank body of the cleaning tank 121. The preset height is the height that the copper ball on the inverted tooth 124 can slide or roll out under the action of gravity and other forces. In the case of the inverted tooth 124 extending in the radial direction, an angle is formed between the tooth extending direction of the inverted tooth 124 and the radial direction, in other words, an extension line of the tooth extending direction of the inverted tooth 124 does not intersect with the cylinder axis of the drum 122.

The cell body of filter-tank 123 is located it is used for receiving to predetermine the high below the pawl 124 sends the copper ball hook to predetermine the copper ball that highly back was poured, just the cell body of filter-tank 123 is in first end extremely the slope of second end side sets up, therefore drops on the filter-tank 123 copper ball can be under the effect of gravity to low landing or roll.

The electroplating copper ball cleaning machine 1 of the embodiment utilizes the feeding sieve 111 of the feeding device 11 to screen the copper balls in the feeding material, so that the copper balls which do not meet the requirement are quickly screened out, and the step of sorting the copper balls is omitted. The copper balls screened by the feeding device 11 slide or roll down from the feeding screen 111 into the drum 122 of the cleaning device 12, and when the drum 122 rotates in the first rotation direction, the copper balls in the drum 122 all slide or roll down to the lower position, so that the cleaning liquid in the cleaning tank 121 can clean the copper balls. When the drum 122 rotates in the second rotation direction, under the action of the inverted tooth 124 and the rotation of the drum 122, the inverted tooth 124 hooks the copper balls located at the lower position to a preset height, and then the copper balls are poured into the filter tank 123. Copper balls in the filter tank 123 can be discharged under the action of gravity, so that automatic sorting and discharging of the cleaned copper balls are realized, the cleaning efficiency of the copper balls is improved, and meanwhile, the potential safety hazard can be reduced because the copper balls do not contact with cleaning liquid directly.
