Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing equipment for electrode plate welds. Background Technology

[0002] Electrode plates in an electrolytic cell play a crucial role in the electrolysis process, providing the reaction site and conducting current. Testing the sealing performance of these plates is a critical step, as it directly impacts their performance and lifespan. Currently, this testing is typically done manually. This method is not only inefficient but also lacks accuracy, consistency, and comprehensiveness. Summary of the Invention

[0003] This application provides a device for inspecting electrode welds, which can not only improve the inspection efficiency of electrode welds, but also enhance the accuracy of the inspection.

[0004] This application provides an electrode weld seam inspection device, which includes a support device and a spraying device. The support device includes a bracket and a drive mechanism. The drive mechanism is disposed on the bracket and matched with the electrode plate. The drive mechanism is used to support the electrode plate and drive the electrode plate to move. The spraying device includes a storage component and a spraying component. The storage component is used to store test reagents. The spraying component is disposed correspondingly to the drive mechanism and connected to the storage component. The spraying component is used to spray the test reagents onto the weld seam on the electrode plate.

[0005] The electrode weld inspection equipment provided in this application includes a drive mechanism in the supporting device that matches the electrode plate. This drive mechanism carries the electrode plate and moves it, facilitating the movement of the weld seam on the electrode plate relative to the spraying assembly. Furthermore, a storage assembly is included in the spraying device to hold the test reagent. The spraying assembly is connected to the storage assembly and corresponds to the drive mechanism, allowing the test reagent to be sprayed onto the weld surface of the electrode plate. Therefore, the electrode weld inspection equipment provided in this application can automatically spray test reagent onto the electrode plate. By controlling the drive mechanism and the spraying assembly, the test reagent can be sprayed evenly and stably onto the weld surface, ensuring that every part of the weld surface has the same amount of test reagent. This enables automated inspection of the sealing performance of the electrode weld and improves inspection efficiency and accuracy.

[0006] In one possible implementation of this application, the storage component includes a storage container and a pressurization component. The storage container is connected to the injection component and is used to hold the test reagent. The pressurization component is connected to the storage container and is used to deliver gas to the storage container to increase the pressure inside the storage container. When the pressure inside the storage container increases, the test reagent flows to the injection component.

[0007] In this application's technical solution, the storage component includes a storage container and a pressurizing component. The storage container holds the test reagents, and the pressurizing component increases the pressure within the container by supplying gas. This pressure applies to the test reagents, allowing them to flow at a higher velocity to the spraying component, which then sprays the reagents onto the electrode plates. Compared to related technologies that use an oil pump to draw test reagents from the storage container, requiring a pipeline connection between the pump and the container, leakage from the pump and pipeline is likely to occur over time. In this embodiment, supplying gas to the storage container via the pressurizing component reduces the risk of leakage.

[0008] In one possible implementation of this application, the storage container includes a first container and a second container. The first container is used to hold contrast agents, and the second container is used to hold developing agents. Both the first container and the second container are connected to a pressurization assembly and to a spray assembly.

[0009] In the technical solution of this application, since the storage container includes a first container and a second container, the first container and the second container can be used to hold the contrast agent and the developing agent respectively, and the pressure applied to the contrast agent and the developing agent can be controlled separately, which facilitates the separate control of the flow rate of the contrast agent and the developing agent.

[0010] In one possible implementation of this application, the spraying assembly includes a first spraying assembly and a second spraying assembly, the first spraying assembly being in communication with a first container, the second spraying assembly being in communication with a second container, and the first spraying assembly and the second spraying assembly being disposed opposite to each other.

[0011] In the technical solution of this application, since the first spraying component and the second spraying component are arranged opposite to each other, the contrast agent and the developing agent can be sprayed simultaneously on two surfaces opposite to each other of the weld. This allows the contrast agent and the developing agent to be sprayed simultaneously to the same position of the weld on the electrode plate. This facilitates the flow of the contrast agent through the defects in the weld to the developing agent and timely contact with the developing agent, thereby improving the accuracy of the weld sealing test.

[0012] In one possible implementation of this application, the first spray assembly includes an adjustment member and a first spray head, the first spray head being connected to a first container via the adjustment member, which is used to adjust the flow rate of the contrast agent flowing to the first spray head.

[0013] In the technical solution of this application, since a first spray head and an adjusting component are provided in the first spray assembly, the spray flow rate and velocity of the contrast agent can be adjusted by the adjusting component, and the flow shape of the contrast agent after it is sprayed out can also be controlled by the first spray head.

[0014] In one possible implementation of this application, the weld inspection equipment further includes a moving device adjacent to the drive mechanism, and a first spraying assembly and a second spraying assembly disposed opposite to the moving device. The moving device is used to drive the first spraying assembly and the second spraying assembly to move toward or away from the drive mechanism.

[0015] In this application's technical solution, since both the first spraying assembly and the second spraying assembly are mounted on a moving device, the moving device can drive the first spraying assembly and the second spraying assembly to move closer to or further away from the driving mechanism. Thus, before the electrode plate is placed on the driving mechanism, the first spraying assembly and the second spraying assembly can be positioned away from the driving mechanism, and after the electrode plate is placed on the driving mechanism, the first spraying assembly and the second spraying assembly can be moved to a position opposite to the weld seam on the electrode plate.

[0016] In one possible implementation of this application, the moving device includes a moving mechanism and an extension arm. The moving mechanism is adjacent to the driving mechanism, the extension arm is disposed on the moving mechanism, and the first spray assembly and the second spray assembly are both disposed on the extension arm. The moving mechanism is used to drive the extension arm to move radially along the driving mechanism.

[0017] In the technical solution of this application, since the moving device includes a moving mechanism and an extension arm, the moving mechanism can generate the power to drive the extension arm to move, and the first spraying component and the second spraying component can be mounted on the extension arm, so that the extension arm can drive the first spraying component and the second spraying component to move to the position corresponding to the weld.

[0018] In one possible implementation of this application, the drive mechanism includes a drive component and a positioning component. The drive component is rotatably mounted on the support, and the positioning component is disposed on the drive component. The drive component is used to carry the nipple plate in the electrode plate and to drive the electrode plate to rotate. The positioning component is used to limit the movement of the electrode plate relative to the drive mechanism.

[0019] In the technical solution of this application, since the driving mechanism includes a driving component and a positioning component, the driving component can support the electrode plate and drive its movement. Furthermore, the positioning component can fix and restrict the electrode plate to the driving component, which helps reduce the risk of the electrode plate shifting relative to the driving component.

[0020] In one possible implementation of this application, the supporting device further includes a guide assembly, with multiple guide assemblies sequentially arranged on the support along the circumference of the drive assembly, and the guide assemblies being used to support the electrode frame of the electrode plate.

[0021] In the technical solution of this application, since multiple guide components corresponding to the electrode frame are provided in the bearing device, the guide components can provide support force to the electrode frame and restrict the rotation of the electrode frame, so that the electrode plate can rotate relative to the same circle, thereby enabling the spraying component to spray the test reagent onto the electrode plate at an accurate position.

[0022] In one possible implementation of this application, the guide assembly includes a support wheel and a limit wheel, both of which are rotatably mounted on a bracket. The rotation axis of the support wheel is parallel to the radial direction of the drive mechanism, and the rotation axis of the limit wheel is perpendicular to the radial direction of the drive mechanism.

[0023] In the technical solution of this application, since the guide assembly includes support wheels and limiting wheels, the pole frame can be supported by multiple support wheels, and multiple guide wheels can be pressed against the side of the pole frame, thereby restricting the pole plate from rotating in a defined area.

[0024] In one possible implementation of this application, the guide component is movably disposed on the bracket along the radial direction of the drive component.

[0025] In the technical solution of this application, since the guide component is movably arranged on the bracket along the radial direction of the drive component, it is convenient to adjust the position of each guide component in the radial direction of the drive component, so that the guide component can be adapted to the pole frame of different diameters, thereby improving the applicability of the pole plate weld inspection equipment.

[0026] In one possible implementation of this application, the electrode weld inspection equipment further includes a control device. The carrying device and the spraying device are both electrically connected to the control device. The control device is configured to control the movement speed of the drive mechanism and to control the flow rate of the spraying assembly spraying the inspection reagent onto the electrode based on the movement speed.

[0027] In the technical solution of this application, since the control device can control the flow rate of the test reagent sprayed by the spraying component onto the electrode plate according to the movement speed of the drive mechanism, an appropriate amount of test reagent can be sprayed on the weld surface of the electrode plate at different movement speeds, which helps to reduce the occurrence of excessive or insufficient spraying of test reagent.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0042] For the sealing inspection of electrode plates in electrolytic cells, existing technologies involve manually applying developing agents and kerosene as a contrast agent to the weld seams on the electrode plates, or allowing kerosene to flow onto the weld seams under gravity. These methods require manual intervention, which is not only complex and risky, but also affects the efficiency and accuracy of the inspection, failing to guarantee consistency and comprehensiveness, thus impacting the reliability of the electrode plate inspection results. Therefore, how to automate the sealing inspection of electrode plate weld seams to improve inspection efficiency and accuracy while reducing operational risks has become an urgent problem to be solved.

[0043] This application provides an electrode plate weld inspection device, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 Schematic diagram of the electrode weld inspection equipment provided in this application Figure 1 , Figure 2 Schematic diagram of the electrode weld inspection equipment provided in this application Figure 2 , Figure 3 Schematic diagram of the electrode weld inspection equipment provided in this application Figure 3 , Figure 4 The structural schematic diagram of the moving device in the electrode weld inspection equipment provided in this application includes...

[0044] The electrode plate weld inspection device provided in this application includes: a supporting device 1 and a spraying device 2; wherein, the supporting device 1 includes a bracket 11 and a driving mechanism 12, the driving mechanism 12 is disposed on the bracket 11 and matched with the electrode plate 4, the driving mechanism 12 is used to support the electrode plate 4 and drive the electrode plate 4 to move; the spraying device 2 includes a storage component 21 and a spraying component 22, the storage component 21 is used to store the test reagent, the spraying component 22 is correspondingly disposed with the driving mechanism 12 and connected to the storage component 21, the spraying component 22 is used to spray the test reagent onto the weld on the electrode plate 4.

[0045] In the embodiments of this application, such as Figure 1 As shown, the electrode plate 4 is typically circular and includes a protruding plate 41 and an electrode frame 42. The electrode frame 42 is arranged around the circumferential edge of the protruding plate 41 and is welded integrally with the protruding plate 41. A test reagent can be applied to the weld between the protruding plate 41 and the electrode frame 42. If defects such as cracks or burn-through exist in the weld, the location of the defects can be determined by the color change of the test reagent. This completes the inspection of the sealing performance of the weld of the electrode plate 4.

[0046] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, a support device 1 matching the electrode plate 4 can be set in the electrode plate weld inspection equipment to support the electrode plate 4 and drive the electrode plate 4 to move, so as to spray the inspection reagent onto the electrode plate 4.

[0047] For example, a bracket 11 and a drive mechanism 12 can be provided in the support device 1 to fix the electrode weld inspection equipment at the work station via the bracket 11, and to install various components in the electrode weld inspection equipment via the bracket 11. For example, the bracket 11 can be configured as a frame structure.

[0048] In another example, the drive mechanism 12 can be configured according to the structural shape of the electrode plate 4. For instance, if the electrode plate 4 is disc-shaped, the drive mechanism 12 can be configured to be approximately circular and capable of rotating autonomously. This allows the drive mechanism 12 to support the electrode plate 4 and drive it to rotate. If the electrode plate 4 is square, the drive mechanism 12 can be configured to be approximately square and capable of linear motion, thus driving the electrode plate 4 to move in a straight line. This facilitates the spraying of inspection reagent onto the circular or linear weld seams on the electrode plate 4.

[0049] In this embodiment, the spraying device 2 is used to spray the test reagent onto the surface of the weld on the electrode plate 4. A storage component 21 and a spraying component 22 can be provided in the spraying device 2, so that the liquid test reagent is contained in the storage component 21, and the test reagent in the storage component 21 is sprayed uniformly onto the surface of the weld at a stable flow rate by the spraying component 22.

[0050] For example, the storage component 21 can be selected according to the characteristics of the test reagent. For instance, the storage component 21 can be a sealable metal container or a sealable plastic container. A portion of the spraying component 22 can be connected to the storage component 21 via a pipe, or a portion of the spraying component 22 can be disposed within the storage component 21. Another portion of the spraying component 22 can be correspondingly disposed with the drive mechanism 12, meaning that another portion of the spraying component 22 can extend above the drive mechanism 12. Devices capable of pressurizing the test reagent can be provided in the spraying component 22 and / or the storage component 21, thereby spraying the test reagent in the storage component 21 onto the surface of the weld at a certain flow rate.

[0051] The electrode weld inspection device provided in this application embodiment has a drive mechanism 12 matching the electrode plate 4 in the supporting device 1. The drive mechanism 12 can support the electrode plate 4 and drive the electrode plate 4 to move, facilitating the movement of the weld on the electrode plate 4 relative to the spraying assembly 22. Furthermore, a storage assembly 21 is provided in the spraying device 2 to hold the test reagent. Simultaneously, the spraying assembly 22 is connected to the storage assembly 21 and corresponds to the drive mechanism 12, allowing the spraying assembly 22 to spray the test reagent onto the weld surface of the electrode plate 4. Therefore, the electrode weld inspection device provided in this application embodiment can automatically spray the test reagent onto the electrode plate 4. By controlling the drive mechanism 12 and the spraying assembly 22, the test reagent can be sprayed evenly and stably onto the weld surface, ensuring that every part of the weld surface has the same amount of test reagent. This enables automated inspection of the sealing performance of the electrode plate 4 weld and improves inspection efficiency and accuracy.

[0052] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the storage component 21 includes a storage container and a pressurization component. The storage container is connected to the injection component 22 and is used to hold the test reagent. The pressurization component is connected to the storage container and is used to deliver gas to the storage container to increase the pressure inside the storage container. When the pressure inside the storage container increases, the test reagent flows to the injection component 22.

[0053] In this embodiment, a storage container and a pressurization component can be provided in the storage component 21. For example, the storage container can be a stainless steel tank with an openable lid and a barrel, which can be closed to form a sealed tank. An outlet can be provided on the stainless steel tank, and the outlet is connected to the spraying component 22 via a connecting pipe.

[0054] For example, the pressurization assembly can employ an air compressor and connecting pipelines. The air compressor can be a reciprocating air compressor, screw air compressor, vane air compressor, scroll air compressor, etc. The air compressor can be connected to the air inlet on the stainless steel tank via the connecting pipeline. In this way, high-pressure gas (such as air) can be delivered into the stainless steel tank by the air compressor. The high-pressure gas increases the pressure inside the stainless steel tank, causing the test reagent inside the stainless steel tank to be subjected to surface pressure and flow from the outlet through the connecting pipeline to the injection assembly 22.

[0055] In the above embodiments, since the storage component 21 includes a storage container and a pressurizing component, the storage container can hold the test reagent, and the pressurizing component can increase the pressure inside the storage container by supplying gas. This applies pressure to the test reagent inside the storage container, allowing it to flow at a higher flow rate to the spraying component, and thus enabling the test reagent to be sprayed onto the electrode plate 4 through the spraying component. Compared to related technologies that use an oil pump to draw test reagents from the storage container, which requires connecting the oil pump and the storage container through a pipeline, and is prone to leakage problems with the oil pump and pipeline over time, the present embodiment uses a pressurizing component to supply gas to the storage container, which reduces the risk of leakage.

[0056] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the storage container includes a first container 211 and a second container 212. The first container 211 is used to hold contrast reagents, and the second container 212 is used to hold developing reagents. Both the first container 211 and the second container 212 are connected to the pressurization assembly and to the spray assembly.

[0057] In this embodiment, the storage container can be configured as a structure comprising two containers, namely a first container 211 and a second container 212. The first container 211 and the second container 212 can have the same structure or different structures. For example, both the first container 211 and the second container 212 can be cylindrical tanks, and their capacities can be set according to the consumption rates of the contrast agent and the developing agent. The contrast agent can be stored in the first container 211, and the developing agent can be stored in the second container 212. The contrast agent can be industrial-grade kerosene with a viscosity of 10 mPa·s to 20 mPa·s and a density of 0.8 g / cm³. 3 Up to 0.9 g / cm 3 .

[0058] For example, both the first container 211 and the second container 212 can be stainless steel tanks with a diameter of 400 mm and a height of 700 mm.

[0059] In another example, both the first container 211 and the second container 212 can be connected to the same set of pressurizing components, or each container can have its own set of pressurizing components. The first container 211 and the second container 212 can then be connected to the spray assembly via connecting pipes. For example, air can be introduced into the first container 211 at a flow rate of 2 L / min to 3 L / min to maintain the pressure inside the first container 211 below 1 MPa. Air can be introduced into the second container 212 at a flow rate of 3 L / min to 4 L / min to maintain the pressure inside the second container 212 below 1 MPa.

[0060] In the above embodiments, since the storage container includes a first container 211 and a second container 212, the first container 211 and the second container 212 can respectively hold the contrast agent and the developing agent, and the pressure applied to the contrast agent and the developing agent can be controlled respectively, so as to facilitate the separate control of the flow rate of the contrast agent and the developing agent.

[0061] In some possible embodiments of this application, such as Figure 4 As shown, the spraying assembly 22 includes a first spraying assembly 221 and a second spraying assembly 222. The first spraying assembly 221 is connected to the first container 211, and the second spraying assembly 222 is connected to the second container 212. The first spraying assembly 221 and the second spraying assembly 222 are arranged opposite to each other.

[0062] In this embodiment of the application, two sets of spraying components 22 can be set up, that is, the first spraying component 221 is connected to the first container 211 through a connecting pipe, and the second spraying component 222 is connected to the second container 212 through a connecting pipe, so that the contrast agent is sprayed to the weld seam through the first spraying component 221, and the developing agent is sprayed to the weld seam through the second spraying component 222.

[0063] For example, the first spray assembly 221 and the second spray assembly 222 can be arranged on the bracket 11 along the axial direction of the drive mechanism 12, that is, the spray nozzle of the first spray assembly 221 and the spray nozzle of the second spray assembly 222 are arranged opposite to each other.

[0064] In the above embodiments, since the first spraying component 221 and the second spraying component 222 are arranged opposite to each other, the contrast agent and the developing agent can be sprayed simultaneously on the two opposite surfaces of the weld. This allows the contrast agent and the developing agent to be sprayed simultaneously to the same position of the weld on the electrode plate 4, which is beneficial for the contrast agent to flow through the defects in the weld to the developing agent and to come into contact with the developing agent in a timely manner, thereby improving the accuracy of the weld sealing test.

[0065] In some possible embodiments of this application, such as Figure 4 As shown, the first spray assembly 221 includes an adjusting member 2212 and a first spray head 2211. The first spray head 2211 is connected to the first container 211 via the adjusting member 2212. The adjusting member 2212 is used to adjust the flow rate of the contrast agent flowing to the first spray head 2211.

[0066] In this embodiment of the application, a first spray head 2211 and an adjusting member 2212 can be provided in the first spray assembly 221 so as to control the shape of the sprayed contrast agent through the first spray head 2211 and adjust the flow rate and flow volume of the contrast agent through the adjusting member 2212.

[0067] For example, the first nozzle 2211 can be configured to spray contrast reagents in a cone, fan, or other shape. The regulating element 2212 can be an electromagnetic flow control valve, which can be positioned between the first container 211 and the first nozzle 2211.

[0068] In another example, the second jet assembly 222 may be configured to include a jet head and an adjustment member 2212, so that the flow rate and velocity of the developing agent jetted by the second jet assembly 222 can be adjusted by the adjustment member 2212.

[0069] In the above embodiments, since the first spraying assembly 221 is provided with a first spraying head 2211 and an adjusting member 2212, the spraying flow rate and velocity of the contrast agent can be adjusted by the adjusting member 2212, and the flow shape of the contrast agent after it is sprayed out can also be controlled by the first spraying head 2211.

[0070] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the electrode weld inspection equipment also includes a moving device 3, which is adjacent to the drive mechanism 12. The first spraying component 221 and the second spraying component 222 are disposed opposite to each other on the moving device 3. The moving device 3 is used to drive the first spraying component 221 and the second spraying component 222 to move towards or away from the drive mechanism 12.

[0071] In this embodiment of the application, the spraying component 22 can be moved relative to the driving mechanism 12 by the moving device 3, so that the spraying component 22 moves to the spraying position corresponding to the weld on the electrode plate 4, or moves the spraying component 22 to a position away from the driving mechanism 12.

[0072] For example, the moving device 3 can be configured to produce linear motion or rotation, and can be positioned on the support 11 adjacent to the drive mechanism 12. For instance, the moving device 3 can produce linear motion along the radial direction of the circular drive mechanism 12, or the moving device 3 can rotate relative to the drive mechanism 12 to a position above or away from the drive mechanism 12. The nozzles of the first spray assembly 221 and the second spray assembly 222 can be positioned opposite each other on the moving device 3.

[0073] In the above embodiment, since both the first spraying assembly 221 and the second spraying assembly 222 are mounted on the moving device 3, the moving device 3 can drive the first spraying assembly 221 and the second spraying assembly 222 to move closer to or further away from the driving mechanism 12. Thus, before the electrode plate 4 is placed on the driving mechanism 12, the first spraying assembly 221 and the second spraying assembly 222 can be positioned away from the driving mechanism 12; and after the electrode plate 4 is placed on the driving mechanism 12, the first spraying assembly 221 and the second spraying assembly 222 can be moved to a position opposite to the weld seam on the electrode plate 4.

[0074] In some possible embodiments of this application, such as Figure 4 As shown, the moving device 3 includes a moving mechanism 31 and an extension arm 32. The moving mechanism 31 is adjacent to the driving mechanism 12. The extension arm 32 is disposed on the moving mechanism 31. The first spray assembly 221 and the second spray assembly 222 are both disposed on the extension arm 32. The moving mechanism 31 is used to drive the extension arm 32 to move radially along the driving mechanism 12.

[0075] In this embodiment, a moving mechanism 31 and an extension arm 32 can be provided in the moving device 3. The moving mechanism 31 can be any mechanism capable of generating linear motion, such as a linear motor, a motor and ball screw, a hydraulic cylinder, a pneumatic cylinder, etc. The extension arm 32 can be provided on the moving part of the moving mechanism 31, and the extension direction of the extension arm 32 is parallel to the movement direction of the moving part of the moving mechanism 31. One end of the extension arm 32 can be fixedly connected to the moving part, and the first spray assembly 221 and the second spray assembly 222 can both be fixed to the other end of the extension arm 32 away from the moving part.

[0076] In the above embodiments, since the moving device 3 includes a moving mechanism 31 and an extension arm 32, the moving mechanism 31 can generate power to drive the extension arm 32 to move, and the first spraying component 221 and the second spraying component 222 can be mounted on the extension arm 32, so that the extension arm 32 can drive the first spraying component 221 and the second spraying component 222 to move to the position corresponding to the weld.

[0077] In some possible embodiments of this application, reference is made to Figure 5 , Figure 5 This is a schematic diagram of the drive assembly 121 in the electrode weld inspection equipment provided in this application. The drive mechanism 12 includes a drive assembly 121 and a positioning assembly 122. The drive assembly 121 is rotatably mounted on the bracket 11, and the positioning assembly 122 is disposed on the drive assembly 121. The drive assembly 121 is used to support the nipple plate 41 in the electrode plate 4 and to drive the electrode plate 4 to rotate. The positioning assembly 122 is used to limit the movement of the electrode plate 4 relative to the drive mechanism 12.

[0078] In this embodiment, the nipple plate 41 in the electrode plate 4 can be supported by the drive assembly 121, and the nipple plate 41 can be rotated by the drive assembly 121. For example, the drive assembly 121 can be configured to include a rotating platform 1211 and a drive member 1212. The rotating platform 1211 can be configured as a flat cylinder and rotatably mounted on the bracket 11. Multiple nipple support plates matching the nipple plate 41 can be provided on the rotating platform 1211. The drive member 1212 can be a motor, which is fixed on the bracket 11, and the output shaft of the motor is connected to the rotating platform 1211 for transmission. For example, a circular rack can be provided on the rotating platform 1211, and a gear matching the circular rack can be provided on the output shaft.

[0079] For example, a positioning component 122 can be provided on the rotary table 1211. For instance, the positioning component 122 can be an electromagnet, which can be positioned between two adjacent nipple support plates. Two electromagnets can be provided on the rotary table 1211 along its circumference. Alternatively, the positioning component 122 can also adopt a structure including a cylinder and a pressure block. The cylinder is fixed to the rotary table 1211, and the pressure block is fixed to the piston rod of the cylinder, so that the cylinder drives the pressure block to move towards the nipple plate 41, thereby pressing the nipple plate 41 against the rotary table 1211.

[0080] In the above embodiments, since the driving mechanism 12 includes a driving component 121 and a positioning component 122, the driving component 121 can carry the electrode plate 4 and drive the electrode plate 4 to move. Furthermore, the positioning component 122 can fix and restrict the electrode plate 4 to the driving component 121, which helps to reduce the risk of the electrode plate 4 moving relative to the driving component 121.

[0081] In some possible embodiments of this application, reference is made to Figure 6 , Figure 6 This is a schematic diagram of the structure of the guide assembly 13 in the electrode weld inspection equipment provided in this application. The support device 1 also includes the guide assembly 13, and multiple guide assemblies 13 are sequentially arranged on the bracket 11 along the circumference of the drive assembly 121. The guide assembly 13 is used to support the electrode frame 42 of the electrode plate 4.

[0082] In the embodiments of this application, such as Figure 3 As shown, a guide assembly 13 matching the pole frame 42 of the pole plate 4 can be provided in the support device 1 to support the pole frame 42 and restrict its movement. For example, multiple guide assemblies 13 can be sequentially arranged around the drive assembly 121 along the circumferential direction of the drive assembly 121.

[0083] For example, a guide disc 134, which is annular, can be provided on the bracket 11 and fixed to the outer periphery of the drive mechanism 12. Ten guide components 13 can be arranged sequentially around the drive component 121.

[0084] Another example, such as Figure 6As shown, the guide assembly 13 can be configured to include a support wheel 132 and a limiting wheel 133. A fixing seat 131 can be provided for the support wheel 132 and the guide wheel, and the fixing seat 131 is mounted on the guide disk 134. Both the support wheel 132 and the guide wheel are rotatably positioned at the end of the fixing seat 131 away from the guide disk 134. The rotation axis of the support wheel 132 is parallel to the radial direction of the drive mechanism 12, and the rotation axis of the limiting wheel 133 is perpendicular to the radial direction of the drive mechanism 12. This allows the support wheels 132 in the multiple guide assemblies 13 to be located on the same virtual plane parallel to the drive assembly 121, and the guide wheels in the multiple guide assemblies 13 to be located on the same virtual circle whose center is on the rotation axis of the drive assembly 121. Thus, the multiple support wheels 132 can support the pole frame 42, while the multiple guide wheels press against the sides of the pole frame 42, thereby limiting the rotation area of ​​the pole plate 4.

[0085] In the above embodiment, since the support device 1 is provided with a plurality of guide components 13 corresponding to the electrode frame 42, the guide components 13 can provide support force to the electrode frame 42 and restrict the rotation of the electrode frame 42, so that the electrode plate 4 can rotate relative to the same circle, and then the spraying component 22 can spray the test reagent onto the electrode plate 4 at an accurate position.

[0086] In some possible embodiments of this application, such as Figure 3 As shown, the guide assembly 13 is movably disposed on the bracket 11 along the radial direction of the drive assembly 121.

[0087] In this embodiment, the guide assembly 13 can be movably mounted on the bracket 11. For example, multiple T-shaped mounting slots can be provided on the guide plate 134, each extending radially along the drive assembly 121. For instance, ten T-shaped mounting slots can be provided on the guide plate 134 fixed to the bracket 11, evenly distributed circumferentially on the guide plate 134. The fixing seat 131 can be configured to match the T-shaped mounting slots. Bolt pairs matching the T-shaped mounting slots can be used to movably mount the fixing seat 131 on the guide plate 134.

[0088] In the above embodiments, since the guide component 13 is movably disposed on the bracket 11 along the radial direction of the drive component 121, it is convenient to adjust the position of each guide component 13 in the radial direction of the drive component 121, so that the guide component 13 can be adapted to the pole frame 42 of different diameters, thereby improving the applicability of the pole plate weld inspection equipment.

[0089] In some possible embodiments of this application, the electrode weld inspection device further includes a control device. The carrying device 1 and the spraying device 2 are both electrically connected to the control device. The control device is configured to control the movement speed of the drive mechanism 12 and to control the flow rate of the spraying assembly 22 spraying the test reagent onto the electrode plate 4 based on the movement speed.

[0090] In this embodiment of the application, the control device may include a microprocessor, for example, the microprocessor may be a programmable logic controller (PLC), and the PLC carrier device 1 and the spraying device 2 may be electrically connected to the PLC, that is, the drive component 1212 of the drive component 121, the pressure component of the spraying device 2, the spraying component 22 of the spraying device 2, etc. may be electrically connected to the PLC.

[0091] For example, the PLC can be configured to control the power of the drive element 1212 in the drive assembly 121, thereby controlling the rotation speed of the rotary table 1211 in the drive assembly 121. The PLC can also be configured to control the power of the pressurizing assembly, thereby controlling the pressure applied by the pressurizing assembly to the storage container. Furthermore, the PLC can be configured to control the operating state of the regulating element 2212 in the spray assembly 22, thereby controlling the flow rate and velocity of the contrast agent sprayed from the first spray assembly 221.

[0092] In another example, the PLC can be configured to control the power of the pressurizing component (the magnitude of the pressure applied to the storage container) and the operating state of the regulating component 2212 based on the power of the drive component 1212 (the rotational speed of the rotary table 1211). For instance, when the rotary table 1211 rotates at a higher speed, the pressurizing component can increase the pressure applied to the storage container to increase the flow rate of the test reagent to the spraying component 22, and increase the spray velocity and flow rate of the spraying component 22, thereby spraying a sufficient amount of test reagent onto the weld of the electrode plate 4. Conversely, when the rotary table 1211 rotates at a lower speed, the pressurizing component can decrease the pressure applied to the storage container to decrease the flow rate of the test reagent to the spraying component 22, and decrease the spray velocity and flow rate of the spraying component 22, thereby reducing the amount of test reagent sprayed and minimizing test reagent waste.

[0093] In the above embodiments, since the control device can control the flow rate of the test reagent sprayed by the spraying assembly 22 onto the electrode plate 4 according to the movement speed of the drive mechanism 12, an appropriate amount of test reagent can be sprayed onto the weld surface of the electrode plate 4 at different movement speeds, which helps to reduce the occurrence of excessive or insufficient spraying of test reagent.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
