[0034] Reference Figure 1 , Figure 1 The structure shown is a cathode plate 200 used in electrolytic refining of non-ferrous metals. The cathode plate 200 includes a starting electrode 210 and a power connection portion 220 connected to one edge of the starting electrode 210. The power connection portion 220 is used to connect electricity during the electrolysis process and is used to be hooked up by a hoist for lifting during transportation and unloading from the tank. The power connection portion 220 includes a lifting lug 221 fixedly connected to the starting electrode 210 and a conductive rod 222 electrically connected to the lifting lug 221. The two ends of the lifting lug 221 can be respectively connected to the two sides of the starting electrode 210 in the thickness direction, and the lifting lug 221 is bent between the two ends fixedly connected to the starting electrode 210. For example, the lifting lug 221 can be bent into a shape that is approximately elliptical. The conductive rod 222 passes through the lifting lug 221 to suspend the starting electrode 210. To ensure that the cathode plate maintains balance during electrolysis and lifting, there can be two lifting lugs 221.

[0035] Optionally, the pole piece 210 is square, and the two lifting ears 221 are arranged side by side and spaced apart on one of the four sides of the pole piece 210. Furthermore, the two lifting ears can be symmetrically arranged.

[0036] See also Figure 2-Figure 4The welding device 100 provided in the embodiment of the present application is used to connect the starting electrode piece 210 and the ear 221. The welding device 100 includes a carrying device 10 and a discharge device 20, wherein the carrying device 10 includes a support plate 11 and a frame 12, and the support plate 11 is used to place the starting electrode piece 210 and the ear 221; the discharge device 20 includes a first electrode 21 and a second electrode 22, the first electrode 21 is movably mounted on the frame 12, and the second electrode 22 is mounted on the support plate 11 and abuts against the starting electrode piece 210 and the ear 2 21, and the first electrode 21 and the second electrode 22 are respectively arranged on both sides of the starting electrode 210 and the hanging ear 221; the connection between the starting electrode 210 and the hanging ear 221 includes a first welding point 230 and a second welding point 240, the first electrode 21 is configured to be able to move close to the second electrode 22 and discharge in turn at the first welding point 230 and the second welding point 240, and the second electrode 22 is configured to cooperate with the first electrode 21 to discharge when the first electrode 21 abuts against the first welding point 230 and the second welding point 240.

[0037] The welding equipment 100 of the embodiment of the present application completes the welding of a single lifting ear 221 and a starting electrode 210 by discharging at the first welding point 230 and the second welding point 240 in sequence through the discharge device 20, thereby improving the connection strength between the starting electrode 210 and the lifting ear 221, ensuring the connection reliability between the starting electrode 210 and the lifting ear 221, and thus ensuring production safety and product quality.

[0038] Optionally, to improve welding efficiency, the number of discharge devices 20 can match the number of lugs 221, that is, each set of discharge devices 20 is used to weld one lug 221. For example, if there are two lugs 221, two sets of discharge devices 20 are also provided.

[0039] Optionally, the support plate 11 is arranged horizontally and the frame 12 can be arranged vertically on the ground. The support plate 11 can be fixedly mounted on the frame 12 and at a certain height from the ground. Exemplarily, the two groups of discharge devices 20 each have a second electrode 22, and the two second electrodes 22 can be arranged side by side and spaced apart on the support plate 11, and the distance between the two second electrodes 22 matches the distance between the two ears 221 at the edge of the starting electrode 210. The ear 221 and the starting electrode 210 can be placed flat on the support plate 11, the ear 221 is bent and the ends of the ear 221 are respectively against the two sides of the thickness direction of the starting electrode 210, and the two ears 221 are respectively placed corresponding to the positions of the two second electrodes 22.

[0040] Optionally, the first welding point 230 and the second welding point 240 can be arranged side by side and spaced apart at the end of the ear 221 along the length of the starting electrode sheet 210 where the ear 221 is located. The first welding point 230 and the second welding point 240 can also be selected at other points where the ear 221 connects to the starting electrode sheet 210, and the first welding point 230 and the second welding point 240 are separated by a certain distance. It is understood that the second electrode 22 can cover the first welding point 230 and the second welding point 240 below the starting electrode sheet 210 and the ear 221.

[0041] See also Figure 4-Figure 6 In some embodiments, the discharge device 20 includes a sleeve 23 and a mounting base 24. The mounting base 24 is movably connected to the frame 12. The first electrode 21 is fixedly mounted on the mounting base 24. The sleeve 23 is sleeved outside the first electrode 21 and elastically connected to the mounting base 24 so that the sleeve 23 can be displaced from the first electrode 21 in the elastic direction.

[0042] In this way, the first electrode 21 and the sleeve 23 are mounted on the mounting base 24, improving structural stability and ensuring that the sleeve 23 and the first electrode 21 can move downward and horizontally synchronously. The sleeve 23 is elastically connected to the mounting base 24, so that when the first electrode 21 moves upward after discharge, the sleeve 23 can still press the lug 221, thereby assisting in separating the first electrode 21 from the starting electrode piece 210 and the lug 221.

[0043] Specifically, the discharge device 20 further includes an elastic member 25. One end of the elastic member 25, along the elastic deformation direction, is fixedly connected to the mounting seat 24, and the other end is fixedly connected to the sleeve 23, thereby elastically connecting the sleeve 23 to the mounting seat 24. The first electrode 21 can be mounted below the mounting seat 24 with the discharge end facing downward. The sleeve 23 is sleeved outside the first electrode 21 and covers at least the discharge end of the first electrode 21. The lower end of the sleeve 23 can be slightly lower than the discharge end of the first electrode 21.

[0044] The elastic member 25 can be deformed in the up and down directions, and the elastic member 25, the sleeve 23 and the first electrode 21 can move synchronously with the mounting base 24. Figure 4 and Figure 5 As shown, before discharge, the discharge device 20 moves downward as a whole until the first electrode 21 presses the first welding point 230 (or the second welding point 240), the lower end of the sleeve 23 presses the starting electrode 210 and the ear 221, the elastic member 25 produces compression elastic deformation, the downward movement of the sleeve 23 is slightly greater than the downward movement of the first electrode 21, and the lower end position of the sleeve 23 is flush with or higher than the discharge end of the first electrode 21.

[0045] like Figure 6As shown, after the first electrode 21 and the second electrode 22 discharge and complete the welding of a welding point, the mounting seat 24 and the first electrode 21 move upward, and the elastic member 25 gradually recovers its deformation and elongation. The lower end of the sleeve 23 still presses against the starting electrode piece 210 and the lug 221, so that the starting electrode piece 210 and the lug 221 remain flat after welding, and also facilitates the separation of the first electrode 21 and the first welding point 230 (or the second welding point 240). After the elastic member 25 fully recovers its deformation, the lower end of the sleeve 23 is lower than the discharge end of the first electrode 21, and the mounting seat 24 and the first electrode 21 continue to move upward until the sleeve 23 is also separated from the starting electrode piece 210 and the lug 221.

[0046] Optionally, the elastic member 25 is a spring 251, which is coaxial with the sleeve 23 and arranged above the sleeve 23. The spring 251 is sleeved outside the first electrode 21 and the upper end of the spring 251 is fixedly mounted on the mounting seat 24, and the lower end of the spring 251 is connected to the upper end of the sleeve 23.

[0047] See also Figure 5 In some embodiments, the discharge device 20 includes a gas filling pipeline 26 , which is disposed on the sleeve 23 . The gas filling pipeline 26 is used to fill the sleeve 23 with protective gas before the first electrode 21 discharges.

[0048] In this way, protective gas is filled into the sleeve 23 through the inflation pipe 26 before the first electrode 21 discharges, which effectively protects the starting electrode 210 and the lug 221 as well as the first electrode 21 and the second electrode 22 from being easily oxidized at the welding point, and also helps to separate the electrode and the lug 221 after welding, thereby meeting the connection strength, appearance and quality requirements of the connection between the lug 221 and the starting electrode 210.

[0049] Specifically, the inflation line 26 may extend through a side wall of the sleeve 23. Alternatively, the inflation line 26 may include a valve or an air tube, and the air tube body may be made of rubber, plastic, metal, or other non-metallic materials. Alternatively, the inflation line 26 may include a hole, a cavity, a gap, or the like.

[0050] The sleeve 23 is mounted outside the first electrode 21. The sleeve 23 surrounds the discharge end of the first electrode 21 and is radially spaced a predetermined distance from the first electrode 21. Before the first electrode 21 discharges, the sleeve 23 and the first electrode 21 compress the starting electrode piece 210 and the lifting lug 221. The starting electrode piece 210, the lifting lug 221, and the sleeve 23 respectively form a discharge space 27 around and below the first electrode 21. The gas filling line 26 is connected to the discharge space 27 to fill the discharge space 27 with protective gas.

[0051] Optionally, the shielding gas is an inert gas such as argon, xenon, or a non-toxic, non-flammable gas such as carbon dioxide, nitrogen, etc.

[0052] Optionally, the welding equipment 100 includes a control system 40, and the inflation pipeline 26 is connected to the control system 40 to automatically control the inflation pipeline 26 to fill the discharge space 27 with protective gas after the first electrode 21 and the sleeve 23 press the starting electrode 210 and the lifting ear 221, thereby reducing manual labor intensity and improving production efficiency.

[0053] See also Figure 2-Figure 3 In some embodiments, the welding equipment 100 includes a thickness measuring device 30, which is installed on the discharge device 20 and moves synchronously with the first electrode 21. The thickness measuring device 30 is used to detect the overlapping thickness of the ear 221 and the starting electrode 210 at the first welding point 230 based on the movement stroke of the first electrode 21 in the thickness direction of the ear 221.

[0054] In this way, the thickness measuring device 30 detects the superimposed thickness of the ear 221 and the starting electrode 210 at the first welding point according to the movement stroke of the first electrode 21 in the thickness direction of the ear 221, so that the discharge device 20 can use appropriate discharge parameters to discharge according to the thickness of each starting electrode 210 and ear 221, thereby improving the welding quality and helping to ensure the connection reliability of the starting electrode 210 and the ear 221.

[0055] Specifically, the thickness measuring device 30 includes a thickness sensor 31, which can be fixedly connected to the mounting base 24 so that the thickness sensor 31 moves synchronously with the first electrode 21. Before discharge, the first electrode 21 moves downward from a certain height above the first welding point 230 to abut the starting electrode piece 210 and the lifting lug 221 at the first welding point 230. As the thickness sensor 31 moves downward synchronously with the mounting base 24 and the first electrode 21, it reads the downward travel of the first electrode 21 and obtains the combined thickness of the starting electrode piece 210 and the lifting lug 221 at the first welding point 230 based on the downward travel.

[0056] It should be noted that, usually, the starting electrode 210 is a thin sheet of uniform thickness, and the lug 221 connecting the starting electrode 210 has a uniform thickness. Therefore, the thickness measuring device 30 can be set on the first electrode 21 used for welding the first welding point 230 to detect the superimposed thickness of the lug 221 and the starting electrode 210 at the first welding point 230, and the superimposed thickness at the first welding point 230 is used as the superimposed thickness of the lug 221 and the starting electrode 210 at the second welding point 240.

[0057] See also Figure 2-Figure 3 In some embodiments, the welding device 100 includes a control system 40, which is electrically connected to the first electrode 21 and the second electrode 22, and the control system 40 is used to control the discharge current of the first electrode 21 and the second electrode 22 at the first welding point 230 and the second welding point 240 to match the stacking thickness.

[0058] In this way, the discharge device 20 can discharge using appropriate discharge parameters according to the thickness of each starting electrode piece 210 and the lifting lug 221 , thereby improving the welding quality and facilitating the connection reliability between the starting electrode piece 210 and the lifting lug 221 .

[0059] Optionally, the control system 40 is installed in the frame 12. The frame 12 may include a crossbeam 121 and a column 122. The column 122 may be formed into a prismatic shape by surrounding plate materials, or may be a column of other shapes. An installation space may be formed within the column 122. The control system 40 includes electrical components such as circuits, electrical components, and a control unit. The control system 40 may be installed in the installation space within the column 122 and electrically connected to the first electrode 21 and the second electrode 22 via wiring within the column 122, the crossbeam 121, and the support plate 11.

[0060] Optionally, the thickness measuring device 30 is electrically connected to the control system 40 to transmit the measured stacking thickness data to the control system 40 .

[0061] See also Figure 1-Figure 3 In some embodiments, the discharge device 20 includes an electrode assembly and a mounting base 24, the mounting base 24 is movably connected to the frame 12, the electrode assembly includes two first electrodes 21 and one second electrode 22, the two first electrodes 21 are arranged in parallel and at intervals on the mounting base 24, and the two first electrodes 21 are used to weld the first welding point 230 and the second welding point 240, respectively.

[0062] Thus, by providing two first electrodes 21 to weld the first welding point 230 and the second welding point 240, electrode loss is reduced. In addition, when the size of the ear 221 is smaller than the movement accuracy of the first electrode 21, using two first electrodes 21 to weld the first welding point 230 and the second welding point 240 separately can also help ensure the accuracy of the movement and positioning of the first electrode 21.

[0063] Specifically, the first electrode 21 can be needle-shaped or rod-shaped. The first electrode 21 is vertically arranged. Both first electrodes 21 are fixedly connected to the mounting base 24. The two first electrodes 21 are installed horizontally side by side and spaced apart. The discharge ends of the two first electrodes 21 are placed downward and can be at the same height.

[0064] Optionally, the starting electrode piece 210 may be connected to two lifting ears 221. The two lifting ears 221 are arranged side by side and spaced apart on one side edge of the starting electrode piece 210, and the two lifting ears 221 may be symmetrically arranged on the starting electrode piece 210. Accordingly, there are two groups of discharge devices 20, each group of discharge devices 20 having two first electrodes 21 and one second electrode 22. The starting electrode piece 210 is placed horizontally on the support plate 11, and the two groups of discharge devices 20 may also be arranged symmetrically in the horizontal direction.

[0065] Each set of discharge devices 20 can be used to weld a lifting ear 221 and a starting electrode 210, and the welding process is as follows: (1) the two first electrodes 21 move downward from the initial height until the first first electrode 21 abuts the first welding point 230; (2) the first first electrode 21 and the second electrode 22 discharge to weld the first welding point 230; (3) the two first electrodes 21 move upward to the initial height and move horizontally so that the second first electrode 21 is opposite to the second welding point 240; (4) the two first electrodes 21 move downward from the initial height until the second first electrode 21 abuts the second welding point 240; (5) the second first electrode 21 and the second electrode 22 discharge to weld the second welding point 240; (6) the two first electrodes 21 move upward back to the initial height.

[0066] In some embodiments, the number of the second welding points 240 is two or more.

[0067] In this way, the connection strength of the welding is improved by multi-point welding, and the connection reliability between the starting electrode 210 and the lifting lug 221 is further improved.

[0068] Specifically, the first welding point 230 is the first welding point among all welding points, and the first welding point 230 and the second welding point 240 can be welded using different first electrodes 21. The first welding point 230 and the plurality of second welding points 240 can form an array or be randomly arranged.

[0069] See also Figure 2-Figure 3 In some embodiments, the welding device 100 includes a first drive device 50 and a second drive device 60, the first drive device 50 is installed on the frame 12, the second drive device 60 is movably connected to the first drive device 50, and the first electrode 21 is connected to the second drive device 60. The first drive device 50 is used to drive the second drive device 60 and the first electrode 21 to move along a first direction (the left and right direction as shown in the figure), and the second drive device 60 is used to drive the first electrode 21 to move along a second direction (the up and down direction as shown in the figure), and an angle is formed between the first direction and the second direction.

[0070] In this way, the first driving device 50 drives the second driving device 60 and the first electrode 21 to move along the first direction, and the second driving device 60 drives the first electrode 21 to move along the second direction, so that the first electrode 21 obtains the freedom of movement in two directions, ensuring the flexibility of movement and the accuracy of positioning of the first electrode 21, thereby facilitating welding operations and improving welding quality.

[0071] Specifically, the frame 12 includes a horizontal beam 121 and a vertical column 122. The horizontal beam 121 can extend horizontally, and the first drive device 50 can be mounted on the horizontal beam 121. The discharge device 20 includes a mounting base 24 for mounting the first electrode 21. The first electrode 21 is fixedly connected to the mounting base 24, and the mounting base 24 is connected to the second drive device 60.

[0074] The first driving device 50 and the second driving device 60 can drive the first electrode 21 to move by electric drive, hydraulic drive, air pump drive, etc., and this application does not impose any limitation on this.

The crossbeam 121 is horizontally positioned between the two uprights 122, with the two sides of the crossbeam 121 facing forward and backward.

[0079] Optionally, there are multiple first limiting members 51, and the multiple first limiting members 51 can all be slidably connected to the same discharge device 20, or each first limiting member 51 can be connected to a separate discharge device 20. For example, there are two discharge devices 20, each of which is used to weld a lifting lug 221. There are also two first brackets 52 and first limiting members 51. The two first limiting members 51 are spaced apart along the second direction on the front surface of the beam 121.

Exemplarily, the drive unit 53 is a linear motor.

[0082] In some embodiments, the welding device includes a detection device (not shown), which is electrically connected to the first electrode and the second electrode, and is configured to generate a detection current between the first electrode and the second electrode.

[0083] In this way, by connecting the first electrode 21 and the second electrode 22 and detecting the welding success rate of the starting electrode piece 210 and the lifting lug 221 with the detection current, the yield rate of the welding process of the starting electrode piece 210 and the lifting lug 221 is guaranteed.

[0084] Specifically, the detection device is electrically connected to the first electrode 21 and the second electrode 22. When the first electrode 21 and the second electrode 22 discharge, the starting electrode 210 and the ear 221 are pressed on the upper and lower sides of the starting electrode 210. Since the starting electrode 210 and the ear 221 are conductive, the first electrode 21 and the second electrode 22 can be powered to form a detection current between the first electrode 21 and the second electrode 22, and the detection current flows through the starting electrode 210 and the ear 221.

[0085] It should be noted that the detection device is executed after the first electrode 21 and the second electrode 22 discharge and before the first electrode 21 moves upward and separates from the lifting lug 221 .

[0086] Optionally, the detection device is integrated with the control system 40 .

[0087] Optionally, the detection device detects whether the welding between the starting electrode piece 210 and the lifting lug 221 is successful by comparing the detection current with a preset current. If the detection current is within the preset current range, the welding between the starting electrode piece 210 and the lifting lug 221 is successful; if the detection current is not within the preset current range, the welding between the starting electrode piece 210 and the lifting lug 221 is unsuccessful.

[0088] The preset current is defined as the current range when the first electrode 21 and the second electrode 22 abut against the connection between the starting electrode 210 and the lifting lug 221 and are powered on in a state where the starting electrode 210 and the lifting lug 221 are successfully welded.

[0089] If the detected current does not exceed the upper and lower limits of the preset current, the starting electrode 210 and the lifting lug 221 are welded successfully, and the starting electrode 210 and the lifting lug 221 are firmly connected at least at the first welding point 230 and the second welding point 240, ensuring the connection reliability of the starting electrode 210 and the lifting lug 221.

[0090] If the detected current exceeds the upper or lower limit of the preset current, the connection between the starting electrode piece 210 and the lifting lug 221 may be desoldering, the material is not in place, the material is insulated, the material thickness exceeds the limit, and other problems may occur, and the welding of the starting electrode piece 210 and the lifting lug 221 is unsuccessful. If the welding is unsuccessful, the position of the starting electrode piece 210 and the lifting lug 221 can be repositioned, the first electrode 21 can be moved, and the welding can be repeated. Alternatively, the starting electrode piece 210 and the lifting lug 221 that were unsuccessfully welded can be removed and disposed of separately as defective products.
