Description

Technical Field

[0001] This utility model relates to the field of flatness measurement technology for electrolytic cell electrode mesh assembly, and specifically to a measuring mechanism for an electrolytic cell electrode mesh assembly flatness measurement and shaping machine. Background Technology

[0002] The electrode mesh assembly of an electrolytic cell includes an electrode frame and electrode meshes connected to the inner edges of both ends of the electrode frame. It is a key component of the electrolytic cell. The flatness of the electrode frame end face of the electrode mesh assembly directly affects the installation reliability of the electrolytic cell, while the flatness of the electrode meshes directly affects the electrolysis performance, efficiency, and service life of the electrolytic cell.

[0003] In existing technologies, after the electrode mesh assembly of an electrolytic cell is manufactured, it is usually necessary to measure the flatness of the electrode mesh assembly to ensure that its flatness meets the design requirements. A typical method for measuring the flatness of the electrode mesh assembly in existing technologies is as follows: the electrode mesh assembly is placed on a testing platform, and then a measuring operator uses multiple general-purpose measuring tools (such as rulers, squares, height gauges, feeler gauges, etc.) to perform multi-point measurements of the flatness of the electrode frame and the electrode mesh. The problems with this method are: manual multi-point measurement is inefficient, its accuracy is not high, and it is difficult to correct any flatness defects found in the electrode mesh.

[0004] To address this, a flatness measurement and shaping machine for electrolytic cell electrode mesh assemblies was developed. This flatness measurement and shaping equipment can automatically fix, measure, and correct the flatness of the electrode mesh assemblies. One of the key issues that needs to be addressed in order to automate the operation of the electrode mesh assembly flatness measurement and shaping machine is how to efficiently and accurately measure the flatness of the two end faces of the electrode frame and the two end faces of the electrode mesh in the electrode mesh assembly. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a measuring mechanism for a flatness measuring and shaping machine for electrolytic cell electrode mesh assemblies, aiming to efficiently and accurately measure the flatness of the two end faces of the electrode frame and the two end faces of the electrode mesh in the electrode mesh assembly. The specific technical solution is as follows:

[0006] A measuring mechanism for a flatness measuring and shaping machine for an electrolytic cell electrode mesh assembly is disclosed. The electrode mesh assembly includes an electrode frame and electrode meshes connected within the electrode frame. The flatness measuring and shaping machine includes a main body for fixing the electrode mesh assembly. The main body includes a fixed vertical frame base and a movable frame pressure plate positioned opposite the vertical frame base and movable relative to the vertical frame base, allowing it to move away from or closer to the vertical frame base. During measurement and shaping, the movable frame pressure plate moves closer to the vertical frame base. The movement of the base presses the electrode frame of the electrode mesh assembly between the vertical frame base and the movable frame pressure plate; the measuring mechanism of the electrolytic cell electrode mesh assembly flatness measuring and shaping machine includes an electrode frame end face flatness measuring device for detecting the flatness of both end faces of the electrode mesh assembly. The electrode frame end face flatness measuring device includes air blowing holes arranged in an array on the vertical frame base and the movable frame pressure plate, respectively. The air blowing holes blow towards the end face of the electrode frame, and each air blowing hole is connected to a constant pressure air supply system through a pneumatic pipeline.

[0007] Before measurement and shaping, the movable frame pressure plate moves away from the vertical frame base, creating a space between the vertical frame base and the movable frame pressure plate for the electrode mesh assembly to move longitudinally into; then the electrode mesh assembly is moved into the space between the vertical frame base and the movable frame pressure plate, and the electrode frame of the electrode mesh assembly is clamped by the movable frame pressure plate.

[0008] As a further improvement of this utility model, grooves are sequentially arranged adjacently along a direction parallel to the edge of the pole frame on the side of the vertical frame base that contacts the pole frame. The air blowing holes are connected to the grooves, and different air blowing holes are connected to different grooves.

[0009] In this design, grooves are sequentially arranged adjacently along a direction parallel to the edge of the pole frame on the side of the movable frame pressure plate that contacts the pole frame. The air blowing holes are connected to the grooves, and different grooves are not connected to each other, while different grooves are connected to different air blowing holes.

[0010] To prevent missed detection of blind spots between adjacent grooves, a further improvement is to stagger the adjacent grooves at their adjacent locations, and the staggering between adjacent grooves is a labyrinthine non-contact winding stagger, so as to ensure that no part is missed in the detection along the entire circumference of the end face of the pole frame near the edge of the pole frame.

[0011] In this invention, each of the pneumatic pipelines connected to different air blowing holes is equipped with a flow meter, and each flow meter is connected to the control system of the electrolytic cell electrode mesh assembly flatness measurement and shaping machine.

[0012] In this invention, the measuring mechanism of the electrolytic cell electrode mesh assembly flatness measuring and shaping machine further includes an electrode mesh flatness measuring device for detecting the flatness of both ends of the electrode mesh of the electrode mesh assembly. The electrode mesh flatness measuring device includes a wire mesh flatness detection rod disposed next to the main body of the flatness measuring and shaping machine and capable of translation in the vertical and horizontal directions, and an inductive proximity sensor disposed on the wire mesh flatness detection rod. The inductive proximity sensor is disposed close to the electrode mesh of the electrolytic cell electrode mesh assembly.

[0013] Preferably, the wire mesh flatness detection rod is perpendicular to the electrode mesh.

[0014] Preferably, the inductive proximity sensor comprises an LC high-frequency oscillator and an amplification processing circuit. When the inductive proximity sensor approaches the electrode mesh, eddy currents are generated inside the metal electrode mesh, causing the oscillation capability of the oscillation circuit to attenuate and the internal circuit parameters to change, thereby detecting the distance to the metal electrode mesh. The closer the electrode mesh is to the inductive proximity sensor, the stronger the induced current, which increases the load in the oscillation circuit, weakening or stopping the oscillation. By acquiring the detection signal data from the inductive proximity sensor, the control system can obtain the flatness data of various points on the electrode frame surface.

[0015] Preferably, the inductive proximity sensor can also be replaced by other types of proximity sensors.

[0016] Preferably, the wire mesh flatness detection rods are positioned on both sides of the flatness measuring and shaping machine main unit to detect the flatness of the electrode mesh of the electrolytic cell electrode mesh assembly from both sides.

[0017] Preferably, the flatness measuring and shaping machine has three-axis moving devices on both sides of the main body, which can realize XYZ three-axis movement, and the wire mesh flatness detection rod is set on the three-axis moving devices.

[0018] The inductive proximity sensor is connected to the control system of the flatness measuring and shaping machine.

[0019] In this invention, frames are respectively provided on both sides of the flatness measuring and shaping machine main unit, and the three-axis moving device is respectively provided on the frames on both sides of the flatness measuring and shaping machine main unit.

[0020] Preferably, the three-axis moving device includes a column, a lifting seat mounted on the column, and a measuring horizontal telescopic shaft mounted on the lifting seat, wherein the wire mesh flatness detection rod is mounted on the measuring horizontal telescopic shaft of the three-axis moving device.

[0021] Preferably, an upper guide rail and a lower guide rail are horizontally arranged at the upper and lower ends of the frame, respectively, and a movable block is arranged on the upper guide rail and the lower guide rail, respectively. The upper and lower ends of the column are respectively fixed on the movable blocks of the upper guide rail and the lower guide rail.

[0022] The vertical frame base, movable frame pressure plate, and pole frame in this utility model are all rectangular frames. However, according to the working principle of this utility model, the vertical frame base, movable frame pressure plate, and pole frame can also be other shapes of ring frames.

[0023] The beneficial effects of this utility model are:

[0024] First, the measuring mechanism of the electrolytic cell electrode mesh assembly flatness measuring and shaping machine of this utility model, by arranging the air blowing holes in an array on the end face that contacts the electrode frame of the electrode mesh assembly, can achieve rapid and high-precision measurement of the flatness of each part of the electrode frame end face at the same time. The control system can detect the air leakage at each part of the electrode frame end face through the flow meter, and judge whether the flatness of each part meets the requirements based on the amount of air leakage. When the amount of air leakage exceeds the preset threshold, an alarm message is issued and the location of the flatness deviation area is given, and relevant personnel are notified to handle it.

[0025] Secondly, the measuring mechanism of the electrolytic cell electrode mesh assembly flatness measuring and shaping machine of this utility model greatly simplifies the structure of electrode frame end face flatness measurement by sequentially and adjacently setting grooves along the circumference of the electrode frame end face and correspondingly connecting each groove with each air blowing hole. This reduces the number of flow meters required, enables each groove to detect a region on the electrode frame, and through the labyrinthine non-contact winding and staggered setting between adjacent grooves, the entire circumference of the electrode frame end face can be detected, eliminating the detection blind zone and thus improving the reliability of electrode frame end face flatness measurement.

[0026] Third, the measuring mechanism of the electrolytic cell electrode mesh assembly flatness measuring and shaping machine of this utility model realizes rapid and high-precision measurement of the flatness of the electrolytic cell electrode mesh assembly by setting an inductive proximity sensor on a three-axis moving device. The inductive proximity sensor can be adjusted to the optimal detection distance position of the electrode mesh by the measuring horizontal telescopic axis of the three-axis moving device, and the horizontal movement of the inductive proximity sensor is realized by the upper guide rail and the lower guide rail of the frame, and the vertical movement of the inductive proximity sensor is realized by the lifting seat, thereby realizing the full-area detection of the flatness of the electrode mesh.
