Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic feeding device for copper ball liquid level sensing for copper plating wire. Background Technology

[0002] Copper balls (especially phosphor bronze balls) used in copper plating processes are key materials for electroplating anodes. They are mainly used in PCB manufacturing, hardware electroplating, photovoltaic panels and other fields. Their core functions include forming a conductive layer, improving adhesion and corrosion resistance.

[0003] In the prior art, Chinese patent CN108759472A discloses an automated feeding device and method for a phosphorus copper ball production line. It indirectly detects the furnace temperature using a temperature sensor located on the top side of the smelting furnace and controls the feeding hopper space via a hydraulic pump, thereby controlling the amount of raw materials fed, achieving automated feeding, reducing manual labor, and improving production efficiency. However, in practical applications, the copper balls on the copper plating wire are used to replenish the copper ions required by the plating solution after being decomposed by electric current. The copper balls on the copper plating wire are stored at the anode position, placed in a titanium basket, and immersed in the copper plating solution. The standard height of the copper balls in the basket must be higher than the solution level. Currently, replenishment is done manually, which easily leads to problems of too many or too few copper balls. Therefore, we disclose an automatic feeding device for copper ball liquid level sensing for copper plating wire. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an automatic feeding device for copper ball liquid level sensing for copper plating wire, so as to solve the problem that manual copper ball replenishment is prone to having too many or too few copper balls.

[0005] To achieve the above objectives, this utility model provides an automatic feeding device for copper ball liquid level sensing for copper plating wire, comprising a liquid tank, a copper ball tank fixedly connected to the top of the liquid tank, a plurality of feeding hoppers fixedly connected to the bottom of the copper ball tank, a guide plate fixedly connected to one side of the bottom of the feeding hopper, a baffle rotatably connected to the other side of the bottom of the feeding hopper, a dispersion box fixedly connected to the bottom of the feeding hopper, a moving hole provided on one side of the dispersion box, a first connecting rod rotatably connected to one side of the bottom of the baffle, one end of the first connecting rod passing through the moving hole to the outside of the dispersion box and rotatably connected to a second connecting rod, and a connecting rod movably sleeved at the top of the second connecting rod. A sleeve is fixedly connected to the hopper. A connecting spring is fixedly connected to the top end of the second connecting rod. The connecting spring is located inside the cavity of the connecting sleeve. One end of the connecting spring is fixedly connected to the hopper. A connecting plate is fixedly connected to the bottom end of the second connecting rod. A third connecting rod is fixedly connected to one end of the connecting plate. Several storage baskets are fixedly connected to the bottom end of the liquid tank. The storage baskets are located directly below the dispersion box. A squeezing plate is movably sleeved on the bottom end of the storage basket. The third connecting rod passes through the storage basket and is fixedly connected to the squeezing plate. The guide plate and the dispersion box cooperate to seal the bottom end of the hopper.

[0006] Preferably, the storage basket, the extrusion plate, the third connecting rod, the connecting plate, and the second connecting rod are all made of titanium.

[0007] Preferably, a sensor is fixedly connected to the top of the storage basket. The sensor includes a light sensor and a reflector. Both the light sensor and the reflector are fixedly connected to the storage basket. The light sensor and the reflector are symmetrically distributed about the longitudinal central axis of the storage basket.

[0008] Preferably, the guide plate is located in the inner cavity of the hopper, the guide plate is triangular, and the baffle is located below the guide plate.

[0009] Preferably, a flow limiting plate is fixedly connected to the bottom of the dispersion box, a dispersion block is fixedly connected to the middle of the flow limiting plate, and a number of small material holes are equidistantly distributed on the outer side of the flow limiting plate, with a copper ball body movably sleeved in the small material holes.

[0010] Preferably, the sensor is located above the liquid surface inside the medicine tank.

[0011] Preferably, the first connecting rod is disposed within the movable hole.

[0012] Preferably, the dispersion block is located in the middle of the plurality of small material holes, and the dispersion block is conical.

[0013] Preferably, the dispersion block is located below the baffle.

[0014] Preferably, the outer wall diameter of the dispersion box is smaller than the inner wall diameter of the storage basket.

[0015] The beneficial effects of this utility model are as follows: When the second connecting rod moves, it drives the baffle to rotate via the first connecting rod, allowing the copper balls in the hopper to enter the dispersion box through the gap between the baffle and the hopper. As the volume of the copper balls decreases between the extrusion plate and the storage basket, the extrusion plate moves upward, which in turn drives the third connecting rod and the connecting plate to move upward. This causes the second connecting rod to move one end of the first connecting rod upward, while the other end moves downward, causing the baffle to rotate downward. This allows the copper balls in the hopper to fall into the dispersion box and then into the storage basket, completing the automatic feeding of the copper balls. Once enough copper balls are added to the basket, the extrusion plate moves downwards. Then, the first connecting rod drives the baffle to move upwards, preventing the copper balls from falling into the hopper and stopping the addition of copper balls. This allows the copper balls to be automatically replenished according to the remaining amount in the storage basket, and the replenishment amount can be controlled to avoid too many or too few copper balls in the storage basket. This avoids the problem of too many or too few copper balls that are easy to occur when adding copper balls manually, saves labor costs, reduces the workload of manual labor, achieves more accurate addition of copper balls, improves the replenishment efficiency of copper balls, reduces the generation of copper particles, and reduces the impact on the quality of copper-plated wire.

[0016] After falling through the baffle, the copper balls will land on the top of the dispersion block. After being dispersed by the dispersion block, the copper balls will fall along the dispersion block to the top of the flow restrictor. Then, the copper balls will fall one by one through the small feed holes to the outside of the dispersion box, further reducing the occurrence of all copper balls falling from the same direction through the small feed holes. This further disperses the falling points of the copper balls, allowing them to fall into the storage basket in a dispersed manner, preventing the copper balls from accumulating in one place in the storage basket and affecting the reaction between the copper balls and the solution.

[0026] like Figures 1-4As shown, an automatic feeding device for copper ball liquid level sensing for copper wire plating includes a liquid tank 1, a copper ball tank 2 fixedly connected to the top of the liquid tank 1, a plurality of feeding hoppers 3 fixedly connected to the bottom of the copper ball tank 2, a guide plate 4 fixedly connected to one side of the bottom of the feeding hopper 3, a baffle 6 rotatably connected to the other side of the bottom of the feeding hopper 3, a dispersion box 5 fixedly connected to the bottom of the feeding hopper 3, a moving hole 7 opened on one side of the dispersion box 5, a first connecting rod 8 rotatably connected to one side of the bottom of the baffle 6, one end of the first connecting rod 8 passing through the moving hole 7 to the outside of the dispersion box 5 and rotatably connected to a second connecting rod 9, a connecting sleeve 10 movably sleeved at the top of the second connecting rod 9, the connecting sleeve 10 being fixedly connected to the feeding hopper 3, and a connecting spring fixedly connected to the top of the second connecting rod 9. 11. Connecting spring 11 is located inside the connecting sleeve 10. One end of connecting spring 11 is fixedly connected to hopper 3. The bottom end of second connecting rod 9 is fixedly connected to connecting plate 12. One end of connecting plate 12 is fixedly connected to third connecting rod 13. Several storage baskets 15 are fixedly connected to the bottom end of liquid tank 1. Storage baskets 15 are located directly below dispersion box 5. The bottom end of storage basket 15 is movably sleeved with extrusion plate 14. Third connecting rod 13 passes through storage basket 15 and is fixedly connected to extrusion plate 14. Guide plate 4 and dispersion box 5 cooperate to seal the bottom end of hopper 3. Storage basket 15, extrusion plate 14, third connecting rod 13, connecting plate 12 and second connecting rod 9 are all made of titanium. First connecting rod 8 is set in moving hole 7. The outer part of dispersion box 5... The wall diameter is smaller than the inner wall diameter of the storage basket 15. During use, a copper ball box 2 is fixedly connected to the top of the liquid medicine tank 1, fixing the relative positions of the liquid medicine tank 1 and the copper ball box 2. Several feeding hoppers 3 are fixedly connected to the bottom of the copper ball box 2. A guide plate 4 is fixedly connected to one side of the bottom of the feeding hopper 3, and a baffle 6 is rotatably connected to the other side of the bottom of the feeding hopper 3. The guide plate 4 and the dispersion box 5 cooperate to seal the bottom of the feeding hopper 3, allowing the copper ball body 18 inside the copper ball box 2 to enter the feeding hopper 3. The dispersion box 5 is fixedly connected to the bottom of the feeding hopper 3, allowing the copper ball body 18 inside the feeding hopper 3 to enter the dispersion box 5. A moving hole 7 is opened on one side of the dispersion box 5, and a first connecting rod 8 is rotatably connected to one side of the bottom of the baffle 6. One end of rod 8 passes through the moving hole 7 and is rotatably connected to the outside of the dispersion box 5, and a second connecting rod 9 is movably sleeved on the top end of the second connecting rod 9. The connecting sleeve 10 is fixedly connected to the hopper 3, and a connecting spring 11 is fixedly connected to the top end of the second connecting rod 9. The connecting spring 11 is located in the inner cavity of the connecting sleeve 10, and one end of the connecting spring 11 is fixedly connected to the hopper 3. This allows the hopper 3 to restrict the position of the second connecting rod 9 through the connecting spring 11, and to restrict the movement direction of the second connecting rod 9 through the connecting sleeve 10. When the second connecting rod 9 moves, it drives the baffle 6 to rotate through the first connecting rod 8, thereby allowing the copper ball body 18 in the hopper 3 to enter the dispersion box 5 through the gap between the baffle 6 and the hopper 3.A connecting plate 12 is fixedly connected to the bottom end of the second connecting rod 9. A third connecting rod 13 is fixedly connected to one end of the connecting plate 12. Several storage baskets 15 are fixedly connected to the bottom end of the liquid tank 1. The storage baskets 15 are located directly below the dispersion box 5. A pressing plate 14 is movably sleeved at the bottom end of the storage basket 15. The third connecting rod 13 passes through the storage basket 15 and is fixedly connected to the pressing plate 14. After the volume of the copper ball body 18 located between the pressing plate 14 and the storage basket 15 decreases, the pressing plate 14 will move upward, thereby driving the third connecting rod 13 and the connecting plate 12 to move upward. This causes the second connecting rod 9 to drive one end of the first connecting rod 8 to move upward, and the other end of the first connecting rod 8 to move downward, causing the baffle 6 to rotate downward. This causes the copper ball body 18 in the hopper 3 to fall into the dispersion box 5, and then into the storage basket 15, completing the automatic feeding of the copper ball body 18. After enough copper ball body 18 are fed into the storage basket 15, the pressing plate 14 moves downward, and then the first connecting rod 8 drives the baffle 6 to move upward. This design prevents the copper balls 18 from falling from the hopper 3, stopping the addition of copper balls 18. This allows the copper balls 18 to be automatically replenished based on the remaining amount in the storage basket 15, with controllable replenishment to avoid an excessive or insufficient supply. It also avoids the problems of too many or too few copper balls 18 that are easily encountered when manually adding them, saving labor costs, reducing workload, achieving more accurate addition of copper balls 18, improving replenishment efficiency, reducing copper particle generation, and minimizing the impact on the quality of the copper-plated wire. The storage basket 15, extrusion plate 14, third connecting rod 13, connecting plate 12, and second connecting rod 9 are all made of titanium, reducing the impact on current decomposition. The first connecting rod 8 is positioned within the moving hole 7, restricting its movement. Because the outer diameter of the dispersion box 5 is smaller than the inner diameter of the storage basket 15, all copper balls 18 falling from the dispersion box 5 will enter the storage basket 15.

[0027] As a preferred embodiment of this example, Figures 2-4As shown, a sensor 20 is fixedly connected to the top of the storage basket 15. The sensor 20 includes a light sensor and a reflector. Both the light sensor and the reflector are fixedly connected to the storage basket 15. The light sensor and the reflector are symmetrically distributed about the longitudinal central axis of the storage basket 15. The guide plate 4 is located in the inner cavity of the feed hopper 3. The guide plate 4 is triangular. The baffle 6 is located below the guide plate 4. The bottom of the dispersion box 5 is fixedly connected to a flow limiting plate 16. A dispersion block 19 is fixedly connected to the middle of the flow limiting plate 16. Several small material holes 17 are evenly distributed on the outer side of the flow limiting plate 16. A copper ball body 18 is movably sleeved in the small material holes 17. The dispersion block 19 is located in the middle of the several small material holes 17. The dispersion block 19 is circular. A cone-shaped dispersion block 19 is located below the baffle 6. A sensor 20 is located above the liquid surface in the medicine tank 1. The sensor 20 is fixedly connected to the top of the storage basket 15. The sensor 20 includes a light sensor and a reflector, both of which are fixedly connected to the storage basket 15. The light sensor and reflector are symmetrically distributed about the longitudinal central axis of the storage basket 15. This allows the light sensor to determine whether the copper ball bodies 18 in the storage basket 15 have accumulated to the required height by receiving reflected light from the reflector. This helps personnel determine the height of the copper ball bodies 18 in the storage basket 15 and check the height to ensure that the copper ball bodies 18 in the storage basket 15 reach the required height. The flow guide plate 4 is located inside the hopper 3. The flow guide plate 4 is triangular, and the baffle 6 is located below the flow guide plate 4. This allows the flow guide plate 4 to guide the copper ball body 18 in the hopper 3 to roll upwards towards the baffle 6. A flow limiting plate 16 is fixedly connected to the bottom of the dispersion box 5. A dispersion block 19 is fixedly connected to the middle of the flow limiting plate 16. Several small material holes 17 are evenly distributed on the outer side of the flow limiting plate 16. The copper ball body 18 is movably sleeved in the small material holes 17. The dispersion block 19 is located in the middle of the small material holes 17. The dispersion block 19 is conical and located below the baffle 6. This allows the copper ball body 18 to fall onto the upper end of the dispersion block 19 after falling from the baffle 6, and then be dispersed by the dispersion block 19. After the drop point, the copper ball body 18 falls along the dispersion block 19 to the upper end of the flow limiting plate 16. Then, the copper ball body 18 falls one by one through the small material hole 17 to the outside of the dispersion box 5, further reducing the occurrence of the copper ball body 18 falling from the small material hole 17 in the same direction. The drop point of the copper ball body 18 is further dispersed, so that the copper ball body 18 falls into the storage basket 15 in a dispersed manner, avoiding the accumulation of the copper ball body 18 in one place in the storage basket 15, which would affect the reaction between the copper ball body 18 and the solution. The sensor 20 is located above the liquid surface in the medicine tank 1, so that the solution does not affect the sensor 20, and the sensor 20 can also determine the height of the copper ball body 18 above the water surface.
