Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0035] In this application, the word “exemplary” is used to mean “serving as an example, instance, or illustration.” Any embodiment described in this application as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0036] See Figure 1 and Figure 2 An embodiment of the present application provides an electroplating test device, including a test box 100, an electrode plate 300, and a positioning and fixing component.

[0037] The test box 100 includes an electrolytic cell 110 for containing electrolyte. The test box 100 has a length and a width. An electrode plate 300 is disposed within the electrolytic cell 110. A positioning and fixing assembly is provided on the test box 100, located on one side of the opening of the electrolytic cell 110. The positioning and fixing assembly defines a fixing slot 210, into which a portion of the electrode plate 300 is fixed.

[0038] The positioning and fixing assembly includes a supporting member 200 , a fixing member 400 and a connecting member 500 .

[0039] Among them, the support member 200 is arranged on the test box 100 and is located on one side of the opening of the electrolytic cell 110. The support member 200 is provided with a fixing groove 210 on the side along the width direction; the electrode plate 300 is arranged in the electrolytic cell 110, and a portion of the electrode plate 300 is located in the fixing groove 210; the fixing member 400 is arranged in the fixing groove 210, and the connecting member 500 passes through the fixing member 400 and the electrode plate 300 in sequence and is detachably connected to the support member 200. The electrode plate 300 is fixed between the fixing member 400 and the groove wall of the fixing groove 210 in the width direction. The electrode plate 300 is partially immersed in the electrolyte of the electrolytic cell 110 and partially located in the fixing groove 210. The fixing groove 210 can fix the electrode plate 300 so that it remains stable during the experiment. To achieve the fixation of the electrode plate 300, the electroplating test device also includes a fixing member 400 and a connecting member 500. The fixing member 400 is located within the fixing groove 210 and is used to support certain portions of the electrode plate 300. The connecting member 500 passes through the fixing member 400 and the electrode plate 300 in sequence and is detachably connected to the support member 200, thereby securing the electrode plate 300. Thus, the connecting member 500 securely fastens the electrode plate 300 to the support member 200, preventing it from loosening or shifting during experiments.

[0040] The technical solution provided in the present application utilizes a fixing member 400 and a connecting member 500, so that the connecting member 500 passes through the fixing member 400 and the electrode plate 300 and is connected to the support member 200, thereby fixing the electrode plate 300 between the groove wall of the fixing groove 210 and the fixing member 400. Because the connecting member 500 can support the electrode plate 300, and the connecting member 500 is connected to the support member 200, the stability of the connecting member 500 is improved, thereby achieving fixation of the electrode plate 300. This fixing method does not rely on clamping, and there is no situation where the splint is opened too large, causing the splint to fall off. Moreover, since the electrode plate 300 is located between the fixing member 400 and the groove wall of the fixing groove 210, the fixing member 400 and the groove wall can also form a certain fixing effect on the electrode plate 300, thereby improving the reliability of the fixation. In detail, first, a support member 200 is provided on one side of the opening of the electrolytic cell 110 to provide support conditions for the subsequent installation and fixation of the electrode plate 300; then the support member 200 is grooved so that the electrode plate 300 and the fixing member 400 can both be located in the fixing groove 210, providing a fixed position for the electrode plate 300, and then fixed to the support member 200 by using the connecting member 500. Because the support member 200 is in a fixed state, the connecting member 500 is fixed to the support member 200 so that the connecting member 500 is also in a fixed state. The fixing of the connecting member 500 and the support member 200 will pass through the fixing member 400 and the electrode plate 300 in turn, thereby realizing the fixation of the electrode plate 300. This fixing method does not rely on the clamping of the conductive splint, and there is no situation where the splint falls off due to the clamping angle being too large. Furthermore, because the connector 500 sequentially passes through the fixing member 400 and the electrode plate 300, the electrode plate 300 is positioned between the fixing member 400 and the tank wall. The fixing member 400 and the tank wall can clamp the electrode plate 300, further securing it and improving the stability and reliability of the fixation. Furthermore, because the support member 200 does not need to participate in the conductive process, it can be made of an insulating material, which is more cost-effective than the related art where the support member 200 must be made of a conductive material.

[0041] In some embodiments, see Figure 2The fixing groove 210 includes a plate mounting groove 211 and a sliding groove 212. The sliding groove 212 is connected to the plate mounting groove 211, and the sliding groove 212 is longer than the mounting groove. A portion of the electrode plate 300 is disposed within the plate mounting groove 211, and the fixing member 400 is disposed within the sliding groove 212 and can slide along the sliding groove 212, allowing the fixing member 400 to block or avoid the plate mounting groove 211. When the electrode plate 300 needs to be installed on the support member 200, the fixing member 400 is first slid to a position not aligned with the electrode plate mounting groove 211 by using the sliding groove 212, avoiding the electrode plate mounting groove 211; then the electrode plate 300 is placed into the electrode plate mounting groove 211 from the side of the support member 200, so that a portion of the electrode plate 300 is located in the electrolytic cell 110, and then the fixing member 400 is slid to a position aligned with the electrode plate mounting groove 211, so that the fixing member 400 and the inner wall of the electrode plate mounting groove 211 form a clamping effect on the electrode plate 300, and finally the connecting member 500 is passed through the fixing member 400 and the electrode plate 300 and fixed to the inner wall of the electrode plate mounting groove 211, thereby achieving the fixation of the electrode plate 300. The fixation of the electrode plate 300 does not rely on the clamping of the conductive clamp, and there is no risk of the clamp becoming fatigued or even falling due to the need to clamp the support member 200 and the electrode plate 300 at the same time for a long time.

[0042] Furthermore, the fixing member 400 is provided with a first magnetic member 410 at both ends in the length direction, and the sliding groove 212 is provided with a second magnetic member 220 at both ends in the length direction, and the magnetic properties of the first magnetic member 410 and the second magnetic member 220 are opposite. The first magnetic member 410 and the second magnetic member 220 can be magnets with opposite magnetic properties. When the fixing member 400 is moved in the sliding groove 212, the fixing member 400 can be initially fixed and pre-positioned to prevent the fixing member 400 from falling from the sliding groove 212. Specifically, when the fixing member 400 needs to avoid the installation of the electrode plate 300, the fixing member 400 can be moved to the end of the sliding groove 212 away from the electrode plate mounting groove 211. At this time, the first magnetic member 410 will attract the second magnetic member 220 due to opposite charges, thereby achieving initial fixation of the fixing member 400 and preventing the fixing member 400 from sliding freely in the sliding groove 212 and interfering with the installation of the electrode plate 300. After the electrode plate 300 is installed in the electrode plate mounting groove 211, the fixing member 400 slides to a position aligned with the electrode plate mounting groove 211. At this time, the first magnetic member 410 at the other end of the fixing member 400 attracts the second magnetic member 220 at the other end of the sliding groove 212, achieving pre-positioning. Finally, the electrode plate 300 is fixed by using the connecting member 500.

[0043] In some embodiments, the sliding groove 212 includes a positioning groove 2121 and an avoidance groove 2122. The positioning groove 2121 and the avoidance groove 2122 are connected along the length direction. When opening, the positioning groove 2121 and the avoidance groove 2122 are integrally formed, that is, they are opened simultaneously in the same process, ensuring that the positioning groove 2121 and the avoidance groove 2122 can be accurately connected, improving the accuracy, and allowing the fixing member 400 to slide smoothly in the sliding groove 212. The positioning groove 2121 is arranged in alignment with the electrode plate mounting groove 211, and the avoidance groove 2122 is arranged in an offset manner with the electrode plate mounting groove 211. The length of the avoidance groove 2122 in the length direction is not less than the length of the fixing member 400 in the length direction, so that the fixing member 400 can effectively avoid the installation of the electrode plate 300 and can also shorten the length of the sliding groove 212 as much as possible. For example, if the sliding groove 212 is centered at the position where the electrode mounting groove 211 aligns with the sliding groove 212, and the two ends of the sliding groove 212 are symmetrically arranged about this midpoint, then for the fixing member 400 to avoid the electrode mounting groove 211 located in the middle, the length of the sliding groove 212 must be at least three times the length of the fixing member 400. However, in this embodiment, the minimum length of the sliding groove 212 is only twice the length of the fixing member 400. Therefore, the technical solution of this embodiment facilitates shortening the length of the sliding groove 212.

[0044] In some embodiments, see Figure 1 The electroplating test apparatus further includes a position adjustment assembly 600. The position adjustment assembly 600 is disposed on the test box 100 and is located on one side of the opening of the electrolytic cell 110. The position adjustment assembly 600 is movably connected to the support member 200 and is used to drive the support member 200 to move along the width direction, thereby adjusting the position of the support member 200 within the electrolytic cell 110. This, in turn, adjusts the position of the electrode plate 300 connected to the support member 200 within the electrolytic cell 110. Adjusting the position of the electrode plate 300 further facilitates the conduct of the electrolysis test.

[0045] Furthermore, the position adjustment assembly 600 includes a threaded rod 610 and a guide rod 620 .

[0046] The threaded rod 610 is rotatably mounted on the test box 100 and positioned on one side of the opening of the electrolytic cell 110. A guide rod 620 is mounted on the test box 100 and positioned on one side of the opening of the electrolytic cell 110. The guide rod 620 and the threaded rod 610 are arranged longitudinally opposite each other, allowing the guide rod 620 and the threaded rod 610 to span the opening of the test box 100. One end of the support member 200 is slidably mounted on the guide rod 620, while the other end is threadedly connected to the threaded rod 610. When the threaded rod 610 is rotated, the support member 200 is affected by the threaded connection. Because the threaded rod 610 is fixed, the support member 200 moves along the width of the threaded rod 610. Furthermore, because the other end of the support member 200 is mounted on the guide rod 620, the movement of the support member 200 in the width direction is more stable due to the action of the guide rod 620.

[0047] Furthermore, two support members 200 are provided. An electrode plate 300 is fixed on each support member 200, and the two electrode plates 300 are respectively a positive electrode plate and a negative electrode plate. When the electrolysis test is carried out, the corresponding positive electrode plate and the negative electrode plate are respectively connected through external positive and negative cables, thereby realizing the electrolysis of the electrolyte in the electrolytic cell 110. The position adjustment component 600 drives the support member 200 to adjust the position of the positive electrode plate and the negative electrode plate in the width direction, thereby changing the effect of the electrolyte electrolysis, and can also adapt to some electrolytic cells 110 with partitions, so that the two electrode plates 300 can be moved to a position filled with electrolyte.

[0048] Furthermore, the threaded rod 610 includes a first threaded segment 611, a second threaded segment 612 and a smooth segment 613. A smooth segment 613 is provided between the first threaded segment 611 and the second threaded segment 612, and one support member 200 is threadedly connected to the first threaded segment 611, and the other support member 200 is threadedly connected to the second threaded segment 612. The thread direction of the first threaded segment 611 is opposite to the thread direction of the second threaded segment 612. When the threaded rod 610 is rotated, since the thread directions of the two threaded segments are opposite, the two support members 200 will slide toward each other or away from each other as the threaded rod 610 rotates, that is, only the rotation of one threaded rod 610 needs to be controlled to adjust the distance between the two electrode plates 300. Whether the two electrode plates 300 move toward each other or away from each other depends on the direction of rotation of the threaded rod 610. For example, when the worker rotates the threaded rod 610 clockwise, the two electrode plates 300 move closer to each other, and when the worker rotates the threaded rod 610 counterclockwise, the two electrode plates 300 move away from each other.

[0049] In certain embodiments, position adjustment assembly 600 includes a driving source (not shown in the figure). The driving source is connected to threaded rod 610, drives threaded rod 610 to rotate, and realizes the automation of test device. For driving source, servo motor or stepper motor can be adopted, and then by utilizing gear transmission, the rotation of motor is transmitted to threaded rod 610, drives threaded rod 610 to rotate. Gear transmission can be based on the rotating speed of driving source, decelerate or accelerate the proportion of gear, is convenient to control the moving speed of support member 200, avoids support member 200 to move too fast and cause damage, moves too slowly and affects test efficiency and reduces. Of course, in other embodiments, for the rotation of threaded rod 610, also can adopt the mode of manual rotation, as by connecting a turning handle at one end of threaded rod 610, between turning handle and threaded rod 610, lever structure can be set, makes the rotation of threaded rod 610 more effortless.

[0050] In some embodiments, the electrode plate 300 is provided with a plurality of positioning holes 310. A connecting hole 420 is provided on the fixing member 400. The connecting hole 420 is coaxially arranged with one of the plurality of positioning holes 310, and the connecting member 500 passes through the connecting hole 420 and the positioning hole 310 in sequence and is detachably connected to the support member 200. The connecting member 500 is a bolt, so that the connecting member 500 can be threadedly connected to the support member 200. The plurality of positioning holes 310 are arranged at intervals along the depth direction of the electrolytic cell 110. By selecting the connecting hole 420 to be coaxially arranged with one of the plurality of positioning holes 310, and then connecting the fixing member 400 with the connecting member 500, the position adjustment of the electrode plate 300 in the depth direction can be achieved, which is conducive to adapting to electrolytic cells 110 of different depths and electrolytes of different capacities.
