Description

Technical Field

[0001] The invention relates to the technical field of electroplating, in particular to a Hall slot testing machine. Background Art

[0002] Hall cell, also known as Hull cell or Hastelloy cell. Hall cell is an indispensable tool for electroplating research and electroplating process control. When conducting Hall cell test, only a small amount of plating solution is needed. After a short test, the electroplating effect of the plating solution in a wide current density range can be obtained. Since the test is sensitive to the composition of the plating solution and the operating conditions, it is often used to determine the concentration of each component of the plating solution, the type and amount of additives, the electroplating temperature and pH value, and determine the current density range for obtaining a good coating. Hall cell has become an indispensable tool for electroplating research and electroplating process control.

[0003] Since the size of the Hall cell is fixed, most of them are not equipped with a stirring device close to the production site, and it is impossible to obtain a high current density plating solution by changing the distance between the cathode plate surface and the anode plate surface, making it difficult to change the current density of the plating solution in the Hall cell, resulting in low reference value of the test results at the production site. At the same time, before cleaning after the experiment, the wires must be disassembled and the plating solution must be poured out before cleaning can be done. The cleaning work is time-consuming and labor-intensive, which reduces the efficiency of the experiment, and pouring the plating solution is prone to spilling the plating solution, polluting the environment.

[0041] The top of the rotating shaft 7 and the Hall slot 101 are fixedly connected with a support plate 6, and a through hole is provided on the surface of the support plate 6 for the rotating shaft 7 to pass through and be rotatably connected with the fixed axis.

[0044] Embodiment 2, based on the above embodiment:

[0045] See also Figure 1 , Figure 2 and Figure 3 The stirring component in the first embodiment is disclosed as follows. The stirring component includes:

[0046] The bottom of the rotating drum 9 is fixedly connected with two symmetrically distributed fixed blocks 12, the upper surface of one of the fixed blocks 12 is fixedly connected with a rotating rod 13, and the surface of the other fixed block 12 is fixedly connected with a guide rod 131, and the surface of the rotating rod 13 is provided with a reciprocating screw groove, and the end of the rotating rod 13 is connected to the lower surface of the support plate 6 for fixed axis rotation;

[0047] The collar 14 has a through hole 1 for the guide rod 131 to pass through on its surface. The guide rod 131 is slidably connected to the collar 14 through the through hole 1. The collar 14 is threadedly connected to the reciprocating screw groove through a reciprocating nut. A disturbance plate 16 is fixedly connected to the surface of the collar 14. A disturbance plate 2 17 is fixedly connected to the bottom of the rotating drum 9. Two retaining rings 15 are fixedly connected to the surface of the rotating rod 13.

[0048] The inner gear ring 29 is fixedly connected to the lower surface of the support plate 6 , and the top of the rotating rod 13 is fixedly connected with a gear 28 , which meshes with the inner gear ring 29 .

[0049] More specifically, in this embodiment: the rotating drum 9 rotates, driving the rotating rod 13 and the guide rod 131 to rotate around the rotating shaft 7, and the rotating rod 13 and the guide rod 131 rotate around the rotating shaft 7, driving the ring 14 to follow the rotating drum 9 to rotate, and the rotating drum 9 and the ring 14 rotate, driving the disturbance plate 1 16 and the disturbance plate 2 17 to rotate, thereby stirring the plating solution in the Hall cell 101, improving the current density of the plating solution, and ensuring the accuracy of the experimental data, and the rotating rod 13 rotates around the rotating shaft 7, driving the gear 28 to rotate around the rotating shaft 7, and the gear 28 rotates around the rotating shaft 7 through the meshing relationship with the inner gear ring 29, thereby driving the rotating rod 13 to rotate while rotating around the rotating shaft 7, and driving the disturbance plate 1 16 to move vertically back and forth while rotating through the action of the reciprocating screw groove, thereby increasing the stirring range and achieving the effect of vertical disturbance, further improving the uniformity of the plating solution distribution, and increasing the accuracy of the Hall cell experimental data.

[0050] Also, see Figure 1 , Figure 2 and Figure 3 , the air blowing assembly in the first embodiment is disclosed as follows, the air blowing assembly includes a blower 23, the blower 23 is fixedly mounted on the surface of the support plate 6, the output end of the blower 23 is fixedly connected with an air outlet pipe 24, the air outlet pipe 24 passes through the support plate 6 and enters the inside of the drum 9, the end of the air outlet pipe 24 is fixedly connected with a drum cover 8, the drum 9 and the drum cover 8 are connected to each other by a fixed axis, the surface of the rotating shaft 7 located inside the drum 9 is fixedly connected with a spiral plate 11, and the spiral plate 11 is in contact with the inner wall of the drum 9;

[0051] The defoaming component is arranged on the surface of the drum 9 and is used to eliminate bubbles generated during the aeration process to reduce interference with the experiment.

[0052] When the plating solution needs to be stirred, the blower 23 is started to blow the gas through the air outlet pipe 24 onto the spiral plate 11 in the rotating drum 9. The spiral plate 11 and the rotating shaft 7 are rotated by the action of wind force and the structure of the spiral plate 11, and the air continues to move downward through the rotation of the spiral plate 11, and is finally ejected into the plating solution through the opening on the surface of the rotating drum 9. Since the rotating drum 9 is in a rotating state, the air can be blown into the plating solution more evenly, and the pneumatic stirring effect is better. In addition, by setting a defoaming component, the bubbles generated by the blown air can be eliminated, thereby reducing the interference of the air on the test and ensuring the accuracy of the test.

[0053] Also, see Figure 1 , Figure 2 and Figure 3The defoaming component in the third embodiment is disclosed as follows: the defoaming component includes a movable plate 18, a limiting plate 19 is fixedly connected to the surface of the rotating drum 9, a recess is provided on the surface of the movable plate 18 for the limiting plate 19 to extend into and be slidably connected thereto, a floating plate 20 is provided at the bottom of the movable plate 18, a rotating plate 21 is fixedly connected to the upper surface of the movable plate 18 through a connecting rod, a defoaming needle 22 is fixedly connected to the bottom of the rotating plate 21, and the number of the defoaming components is two, and they are symmetrically distributed.

[0054] When plating solution is added into the Hall slot 101 and contacts the floating plate 20, the buoyancy of the floating plate 20 drives the movable plate 18 to slide on the surface of the limiting plate 19. The movable plate 18 moves, driving the rotating plate 21 and the defoaming needle 22 to move, so that the rotating plate 21 is always located above the plating solution. When air is blown, bubbles continuously move from the inside of the plating solution to the liquid surface. At this time, the rotating drum 9 rotates, driving and driving the rotating plate 21 to rotate through the limiting plate 19. The rotating plate 21 rotates, so that the defoaming needle 22 contacts the bubbles, thereby eliminating the bubbles, thereby preventing excessive bubbles from affecting the quality of the experiment.

[0055] Also, see Figure 1 , Figure 2 and Figure 3 The cleaning component in the first embodiment is disclosed as follows. The cleaning component includes a pump body 25, which is fixedly mounted on the upper surface of the support plate 6. The input end and the output end of the pump body 25 are respectively fixedly connected to a water outlet pipe 26 having a water inlet pipe 27. The end of the water inlet pipe 27 is located at the bottom of the heating chamber 102. The water outlet pipe 26 passes through the support plate 6 and the drum cover 8 and extends into the interior of the rotating drum 9. The water outlet pipe 26 is located above the spiral plate 11, and a valve is provided on the surface of the discharge pipe 103.

[0056] When the experiment is completed and the tank body needs to be cleaned, first open the valve of the drain pipe 103 to collect the plating solution in the tank body without directly dumping it to prevent pollution to the environment. Then start the pump body 25 to transport the water in the heating chamber 102 to the drum 9 through the water inlet pipe 27 and the water outlet pipe 26, and the spiral plate 11 is driven to rotate by the impact force of the water flow, and the rotating shaft 7 and the drum 9 are driven to rotate by the spiral plate 11, and finally the water flows through the opening opened on the surface of the drum 9 and sprays on the inner wall of the Hall tank 101, thereby achieving the effect of automatic cleaning. The clean water in the heating chamber 102 is used for cleaning, making full use of resources, saving time, and no need to remove the wires, so as to facilitate the rapid implementation of subsequent experiments and improve experimental efficiency.

[0057] Embodiment 3, based on the above embodiment:

[0058] See also Figure 1 , Figure 2 and Figure 3The surface of the cathode wall 1011 is provided with a clamping component for limiting the cathode sheet, and the clamping component includes:

[0059] Two fixing plates 32, both fixing plates 32 are fixedly connected to the surface of the cathode wall 1011 and are symmetrically distributed, and grooves 321 are formed on the surfaces of the fixing plates 32;

[0060] The clamping rod 34 and the driving rod 33, the inner wall of the groove 321 is provided with a slot 1 for the clamping rod 34 to extend into, the upper surface of the fixing plate 32 is provided with a slot 2 for the driving rod 33 to extend into and slidably connected thereto, the slot 1 is communicated with the slot 2, the end of the driving rod 33 is fixedly connected to the end plate, the surface of the driving rod 33 is sleeved with a spring 2 38, and the two ends of the spring 2 38 are respectively fixedly connected to the surface of the end plate and the surface of the fixing plate 32;

[0061] A cavity 322 is provided inside the sleeve plate 37 and the fixed plate 32, and the sleeve plate 37 is slidably connected in the cavity 322. The sleeve plate 37 is fixedly connected to the surface of the clamping rod 34. A spring 1 36 is fixedly connected between the sleeve plate 37 and the inner wall of the cavity 322. A driving groove 331 is provided on the surface of the driving rod 33 for the clamping rod 34 to extend into. The driving groove 331 includes an inclined portion. The end of the clamping rod 34 is arc-shaped, and a clamping plate 35 is fixedly connected to the end of the clamping rod 34. The elastic force of the spring 2 38 is greater than the elastic force of the spring 1 36. There are multiple groups of clamping rods 34 and clamping plates 35, which are evenly distributed on the inner wall of the groove 321.

[0062] More specifically, in this embodiment, when the cathode sheet is placed, since the cathode sheet is relatively thin, it is easy to shake during the experiment. Figure 7 and Figure 8 As shown, at this time, spring 2 38 is already in a stretched state, and the cathode sheet is placed in the groove 321 between the two fixed plates 32, so that both ends of the cathode sheet extend into the groove 321, and then the drive rod 33 can be released, and the drive rod 33 is driven to move downward by the elastic restoring force of spring 2 38, and the drive rod 33 moves downward, and pressure is applied to the clamping rod 34 through the driving groove 331, pushing the clamping rod 34 to move toward the cathode sheet, and driving the sleeve plate 37 to slide in the cavity 322, while applying pressure to the spring 1 36 to shrink it, so that it moves toward the cathode sheet through the clamping rod 34, driving the clamping plate 35 to move toward the cathode sheet until the cathode sheet is clamped, and by providing multiple clamping plates 35, the stability of the clamping is improved, ensuring that the cathode sheet will not shake during the experiment, improving the stability of the experiment, and thereby increasing the accuracy of the data.

[0063] Also, see Figure 1 , Figure 2 and Figure 3A temperature detector 39 is disposed on the inner wall of the Hall slot 101 , and two groups of special-shaped heating rods 30 are disposed in the heating chamber 102 .

[0064] By setting a temperature detector 39 to detect the temperature in the Hall slot 101 in real time, and controlling the opening and closing of the special-shaped heating rod 30 according to the detected temperature, the temperature in the Hall slot 101 is always at an appropriate degree to ensure the accuracy of the experimental data. By setting a heating chamber 102, the water body is heated and the heat is transferred to the Hall slot 101 through the water body. Compared with directly placing the heating rod in the plating solution for heating, the heat conduction of the water body can make the plating solution heated and the temperature distribution significantly more uniform, which is more conducive to improving the accuracy of the Hall slot test.

[0065] Also, see Figure 1 , Figure 2 and Figure 3 A control switch 31 is fixedly provided on the surface of the shell 1. The control switch 31 is signal-connected with the pump body 25, the blower 23 and the special-shaped heating rod 30. When in use, the control switch 31 is used to facilitate the experimenter to control the opening and closing of the pump body 25, the blower 23 and the special-shaped heating rod 30.

[0066] Working principle: When using the Hall slot tester, the following steps are included:

[0067] Step S1: First, the prepared anode plate and cathode plate are respectively installed on the anode wall 1012 and cathode wall 1011 corresponding to the Hall cell 101, and the test DC power supply is connected through wires, and then the test plating solution is poured into the Hall cell 101, and the excess plating solution can be discharged through the overflow port 5 to ensure that the plating solution is at a suitable liquid level;

[0068] Step S2: After the plating solution is added, pour an appropriate amount of clean water into the heating chamber 102, and then heat the clean water through the special-shaped heating rod 30 to transfer the heat to the Hall tank 101. After the plating solution in the Hall tank 101 is heated to a suitable temperature, the experiment can be started;

[0069] Step S3: During the experiment, the air is blown onto the spiral plate 11 in the rotating drum 9 through the air outlet pipe 24 by the blower 23, and the spiral plate 11 and the rotating shaft 7 are driven to rotate by the wind force, and finally the air is sprayed into the plating solution through the opening on the surface of the rotating drum 9. Since the rotating drum 9 is in a rotating state, the air can be blown into the plating solution more evenly, and the pneumatic stirring effect is better.

[0070] Step S4: by rotating the drum 9, the rotating rod 13 and the guide rod 131 are driven to rotate around the rotating shaft 7, and the sleeve ring 14 is made to rotate along with the rotating drum 9. By rotating the drum 9 and the sleeve ring 14, the disturbance plate 16 and the disturbance plate 2 17 are driven to rotate, and the plating solution in the Hall cell 101 is stirred to improve the current density of the plating solution and ensure the accuracy of the experimental data. By rotating the rotating rod 13 around the rotating shaft 7, the gear 28 is driven to rotate around the rotating shaft 7, so that the rotating rod 13 rotates while rotating around the rotating shaft 7, and the disturbance plate 1 16 is driven to move vertically back and forth while rotating through the action of the reciprocating screw groove, thereby increasing the stirring range, achieving the effect of vertical disturbance, and increasing the accuracy of the Hall cell experimental data;

[0071] Step S5: When the experiment is completed, first open the valve of the drain pipe 103 to collect the plating solution in the tank body without directly dumping it to prevent pollution to the environment, and then start the pump body 25 to transport the water in the heating chamber 102 to the drum 9 through the water inlet pipe 27 and the water outlet pipe 26, and the spiral plate 11 is driven to rotate by the impact force of the water flow, and finally the water flow outlet is sprayed on the inner wall of the Hall tank 101, achieving the effect of automatic cleaning, without removing the wires, saving time, facilitating the rapid progress of subsequent experiments, and improving experimental efficiency.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
