Description

Technical Field

[0001] The utility model relates to the technical field of magnetic property measurement of silicon steel sheet samples, in particular to a silicon steel sheet separation mechanism and a silicon steel sheet sample magnetic property measurement system. Background Art

[0002] Silicon steel sheets, also known as electrical steel, are important soft magnetic alloys that are indispensable to electricity, electronics, new energy vehicles and other industries. They are often used to make iron cores for various transformers, motors and generators. The production process of silicon steel sheets is relatively complicated. In order to ensure its performance parameters, it is necessary to test the silicon steel sheets after production. At present, the measurement of the magnetic properties of silicon steel sheets uses the Epstein square circle test in both international and domestic standards. The test samples need to be selected in different numbers according to their thickness. The samples need to be cross-passed into the Epstein square circle one by one from four directions to measure the magnetic properties. After the measurement is completed, the samples are extracted from the square circle for other processing. There are currently two ways to extract samples: manual and machine automation.

[0003] In the existing automated testing equipment for the magnetic properties of silicon steel sheets, the samples are stacked crosswise in the Epstein square circle. The equipment usually uses a clamp to clamp one end of the silicon steel sheet for direct extraction. When the sample is thin, the number of samples to be tested increases. At the same time, it is easier to form vacuum adsorption between the thin sheets, resulting in a significant increase in friction. Therefore, for thinner samples (such as less than 0.25 mm), the above-mentioned equipment generally has problems such as difficulty in sample extraction and sheet leakage, resulting in a high failure rate when testing such samples, requiring frequent manual intervention, and low detection efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a silicon steel sheet separation mechanism and a silicon steel sheet sample magnetic property measurement system, which can greatly improve the success rate of the square ring magnetic property automated detection equipment for extracting thin samples.

[0005] A silicon steel sheet separation mechanism comprises a slide, a lifting component, a mounting component and a separation head, wherein the slide is mounted on a workbench of an Epstein square circle measuring station, the lifting component is arranged on the slide, the mounting component is mounted on the lifting component and is away from the slide, and the separation head is fixed on the mounting component;

[0006] The slide and the lifting component constitute a moving component, and the moving component is used to drive the separation head to and from the working point and the standby point. The separation head is used to separate the silicon steel sheet samples stacked in the Epstein square circle at the working point.

[0007] The above-mentioned silicon steel sheet separation mechanism is based on the sample extraction requirements of the Epstein square circle measuring station. A corresponding sample separation mechanism is added to the workbench. When the clamp of the unloading manipulator grabs one end of the sample to be extracted, the separation head moves to the working point, such as near the other end of the sample, with the help of a moving part composed of a slide and a lifting part. The introduced separation head generates an external force to destroy the vacuum adsorption adhesion between the samples, reducing the friction between the samples, so that the clamp can perform the existing extraction and placement actions along the extraction direction under the drive of the mechanical arm of the unloading manipulator; after the extraction and placement are completed, the separation head moves to a position away from the Epstein square circle, that is, the standby point, with the help of a moving part, waiting for the next sample separation without interfering with the original work of the Epstein square circle measuring station. Compared with the traditional Epstein square circle measuring station, the above-mentioned mechanism added to the workbench of the Epstein square circle measuring station has greatly improved the success rate of the square circle magnetic property automatic detection equipment for extracting thin samples.

[0008] In one embodiment, the separation head is a compressed air spray gun, and the mounting component is a spray gun fixing block.

[0009] In one embodiment, the spray gun fixing block is a threaded fastening type fixing seat.

[0010] In one embodiment, the separation head is an electromagnet and the mounting component is a mounting bracket.

[0011] In one embodiment, the mounting bracket is a wedge-shaped bracket and is threadedly connected to the lifting component.

[0012] In one embodiment, the slide is a pneumatic slide or a linear motor slide.

[0013] In one embodiment, the lifting component is a lifting cylinder or a linear motor lifting module.

[0014] A silicon steel sheet sample magnetic property measurement system comprises an Epstein square ring measurement station and the above-mentioned silicon steel sheet separation mechanism.

[0015] The above-mentioned silicon steel sheet sample magnetic property measurement system, by adding a corresponding silicon steel sheet separation mechanism on the workbench of the Epstein square circle measurement station, generates external force through the introduced separation head to destroy the vacuum adsorption adhesion between the samples, reduces the friction between the samples, and greatly improves the success rate of the square circle magnetic property automated detection equipment in extracting thin samples.

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 As shown, the samples (such as the silicon steel sheet samples mentioned below) 009 in the Epstein square circle 001 are stacked crosswise with each other. When the sample sheet is thin, the number of samples to be tested increases. At the same time, vacuum adsorption is easily formed between the thin sheets, resulting in a significant increase in friction, making extraction difficult.

[0025] In one embodiment, reference Figure 2, a silicon steel sheet separation mechanism 100 is provided, comprising a slide 101, a lifting component 102, a mounting component 103 and a separation head 104. The slide 101 is mounted on a workbench of the Epstein square circle measuring station. The lifting component 102 is arranged on the slide 101. The mounting component 103 is mounted on the lifting component 102 and away from the slide 101. The separation head 104 is fixed on the mounting component 103. The slide 101 and the lifting component 102 constitute a moving component, which is used to drive the separation head 104 to and from the working point and the standby point, and the separation head 104 is used to separate the stacked silicon steel sheet sample 009 in the Epstein square at the working point.

[0026] It can be understood that the slide 101 is a component used to provide lateral (i.e., along the plane where the workbench is located) movement for the components installed thereon, and can be, but not limited to, an existing electric slide, mechanical slide, linear motor module, hydraulic slide, ball screw module or magnetic suspension slide, as long as it can be used to provide the above-mentioned required lateral movement function. The lifting component 102 is a component used to provide longitudinal (i.e., perpendicular to the plane where the workbench is located) movement for the components installed thereon, and can be, but not limited to, an existing electric lifting column, hydraulic lifting cylinder, mechanical lift, servo lifting system, linear motor lifting module or magnetic suspension lifting device, as long as it can be used to provide the above-mentioned required longitudinal movement function.

[0027] The separation head 104 can realize sample separation by, but not limited to, mechanical separation, magnetic separation or air knife separation. All of the above components can be uniformly and collaboratively controlled by the industrial control unit of the equipment system where the Epstein square circle measurement station is located. These components are used in various workshop scenes respectively, so their respective control methods can directly use the inherent control plug-in of the component itself to realize control support, without additional adaptation or interface adjustment, plug and play, and the components are easy and fast to install and use, and the cost is not high.

[0028] The moving parts composed of the slide 101 and the lifting part 102 can provide the separation head 104 with multi-directional movement ability, so that the separation head 104 can move to the working point in time when the sample needs to be separated, and can move to the standby point when the sample does not need to be separated. This can not only cooperate with the sample extraction operation of the unloading robot in the Epstein square circle measuring station, but also avoid interfering with the normal driving of the Epstein square circle by the rotating platform on the workbench in the Epstein square circle measuring station. It can be better integrated into the work of the Epstein square circle measuring station and is more convenient to use.

[0029] The above-mentioned silicon steel sheet separation mechanism 100 is based on the sample extraction requirements of the Epstein square circle measuring station, and a corresponding sample separation mechanism is added on the workbench. When the clamping claw of the unloading robot grasps one end of the silicon steel sheet sample 009 to be extracted, the separation head 104 is moved to the working point with the help of the moving parts composed of the slide 101 and the lifting part 102, such as near the other end of the silicon steel sheet sample 009. The external force generated by the introduced separation head destroys the vacuum adsorption adhesion between the samples, reduces the friction between the samples, so that the clamping claw can perform the existing extraction and placement actions along the extraction direction under the drive of the mechanical arm of the unloading robot; after the extraction and placement are completed, the separation head 104 is moved to a position away from the Epstein square circle with the help of the moving parts, that is, the standby point, and waits for the next sample separation without interfering with the original work of the Epstein square circle measuring station. Compared with the traditional Epstein square ring measuring station, the above-mentioned mechanism added to the workbench of the Epstein square ring measuring station has greatly improved the success rate of the square ring magnetic property automated testing equipment in extracting the thinner silicon steel sheet sample 009.

[0030] It should be noted that there may be a variety of mechanical structural connection methods between the slide 101, the lifting component 102, the mounting component 103 and the separation head 104, such as but not limited to bolt connection, clamping, riveting or welding, etc. The mounting component 103 and the separation head 104 are detachable, which facilitates the rapid replacement of the separation head after damage and the adjustment of the installation position of the separation head 104.

[0031] In one embodiment, the separation head 104 is a compressed air spray gun, and the mounting component 103 is a spray gun fixing block. It can be understood that in this embodiment, a compressed air spray gun can be used as a component for generating the external force required for sample separation. The compressed air spray gun can be connected to the air source near the workbench of the Epstein square circle measurement station through an air supply pipeline to support the stable air supply when the compressed air spray gun is working. When the compressed air spray gun is working, the angle and position of the jet can be adjusted by adjusting the spray gun fixing block to find a suitable blowing direction, thereby achieving a better sample separation effect. The spray gun fixing block can be installed with a compressed air spray gun by, but not limited to, snap-on, threaded connection, or magnetic suction, and supports multi-directional adjustment of the compressed air spray gun.

[0032] refer to Figure 3 One of the structural examples shown is used to illustrate the process of separating and extracting the silicon steel sheet sample 009: the Epstein square ring 001 is installed on the rotating platform 004 on the workbench 003, and the clamp 002 is installed on the mechanical arm of the unloading manipulator. After the magnetic property measurement of the silicon steel sheet sample 009 is completed, the clamp 002 is moved to Figure 3101 and 102; at the same time, the compressed air spray gun moves to the working point where the samples are stacked and intersected by means of a moving part composed of a slide 101 and a lifting part 102, and blows air to the intersection to create an air gap between the silicon steel sheet samples 009, thereby destroying the vacuum adsorption adhesion between the samples and reducing friction; at the same time, the clamping jaw 002 performs extraction and placement actions along the extraction direction driven by the mechanical arm; after the extraction and placement are completed, the compressed air spray gun uses The moving part composed of the slide 101 and the lifting part 102 moves to a standby position away from the Epstein square circle 001, and then the rotating platform 004 drives the Epstein square circle 001 to rotate 90° in the clockwise direction, placing the next group of samples in the extraction position, and the clamp 002 and the compressed air spray gun repeat the action of the previous round to extract the samples; after that, the rotating platform 004 continues to rotate 90° in the clockwise direction, and repeats the above operation until all four groups of samples in the Epstein square circle 001 are extracted.

[0033] In one embodiment, the spray gun fixing block is a threaded fixing seat. Figure 3 The threaded fastening fixing seat shown is used as a spray gun fixing block for a compressed air spray gun. The compressed air spray gun can pass through the mounting hole of the threaded fastening fixing seat and the tightness can be adjusted by the screws thereon. The threaded fastening fixing seat can be rotatably mounted on the lifting component 102 by means of a pin, screw, buckle or other connecting part to support quick disassembly and assembly and adjustment of the blowing direction of the compressed air spray gun.

[0034] In one embodiment, the separation head 104 is an electromagnet, and the mounting component 103 is a mounting bracket. It can be understood that in this embodiment, an electromagnet can be used as a component for generating the external force required for sample separation, and the electromagnet can be powered by a power supply near the workbench of the Epstein square circle measuring station to provide the power supply required for the electromagnet to work; accordingly, a mounting bracket with a structural shape matching the electromagnet used can be used to install the electromagnet, such as but not limited to a straight-tube mounting bracket (the electromagnet can be embedded in the mounting hole reserved at its end), a telescopic or fixed-length rod-shaped mounting bracket (the electromagnet can be screwed and fixed on the mounting screw reserved at its end) or other structural types of brackets, and the mounting bracket and the lifting component 102 can be fixedly connected, detachably connected or rotatably connected, or a combination of several connection methods, as long as the adjustment function required for the electromagnet to work at the working point can be provided. The alignment and spacing between the electromagnet and the silicon steel sheet sample 009 can be adjusted by the mounting bracket to achieve a better magnetic separation effect.

[0035] refer to Figure 4Another structural example is shown to illustrate the process of separating and extracting the silicon steel sheet sample 009: the Epstein square ring 001 is installed on the rotating platform 004, and the clamp 002 is installed on the mechanical arm of the unloading manipulator. After the magnetic property measurement of the silicon steel sheet sample 009 is completed, the clamp 002 moves to Figure 4 , and grasp one end of the silicon steel sheet sample 009 to be extracted; at the same time, the electromagnet is moved to a working point near the end of another group of silicon steel sheet samples 009 orthogonal to the silicon steel sheet sample 009 to be extracted by means of a moving component composed of a slide 101 and a lifting component 102, and the electromagnet is energized to generate a magnetic field. At this time, the silicon steel sheet samples 009 adjacent to the pole surface of the electromagnet generate a same-pole repulsive force and a gap appears, thereby reducing the overlapping effect on the silicon steel sheet sample 009 on the extracted side, thereby reducing the friction when the sample is extracted; at the same time, the clamping jaw 002 is driven by the mechanical arm to execute along the extraction direction Extraction and placement action; after the extraction and placement are completed, the electromagnet is powered off and moved to a standby position away from the Epstein square circle 001 with the help of a moving component composed of a slide 101 and a lifting component 102, and then the rotating platform 004 drives the Epstein square circle 001 to rotate 90° clockwise, placing the next group of silicon steel sheet samples 009 in the extraction position, and the clamp 002 and the electromagnet repeat the action of the previous round to extract the silicon steel sheet sample 009; the rotating platform 004 continues to rotate 90° clockwise, and repeats the above operation until all four groups of samples in the Epstein square circle 001 are extracted.

[0036] In one embodiment, the mounting bracket is a wedge-shaped bracket and is threadedly connected to the lifting component 102. It can be understood that in this embodiment, the mounting bracket is a wedge-shaped bracket and is threadedly connected to the lifting component 102. Figure 4 The wedge-shaped bracket shown in the figure serves as a mounting bracket for the electromagnet, and one end of the wedge-shaped bracket is threadedly connected to the lifting component 102. Accordingly, the electromagnet is in the shape of a straight cylindrical structure, which can be bonded, screwed or clamped to the other end of the wedge-shaped bracket. The wedge-shaped bracket can adopt a hollow structure design to reduce its weight, thereby ensuring sufficient structural strength and ease of disassembly and assembly, while reducing the weight of the entire mechanism and saving costs.

[0037] In one embodiment, the slide 101 is a pneumatic slide or a linear motor slide. It is understood that in this embodiment, the slide 101 can adopt a pneumatic slide, which is an integrated pneumatic component, mainly composed of a slide, a cylinder, a guide rail and a related control system, which can be used for precise assembly, positioning and movement of the lifting component 102, and the corresponding series and model can be selected according to the actual application requirements. The slide 101 can also adopt a linear motor slide, which is a slide driven by a linear motor. Compared with the traditional electric slide, it can provide the advantages of high precision, low friction, fast response, environmental protection and energy saving, high intelligence and convenient maintenance, can support more efficient mobile control and is more suitable for the intelligent upgrade application of the Epstein square circle measurement station, and has stronger applicability.

[0038] In one embodiment, the lifting component 102 is a lifting cylinder or a linear motor lifting module. It can be understood that in this embodiment, the lifting component 102 can adopt a lifting cylinder or a linear motor lifting module, wherein the lifting cylinder is a common pneumatic actuator, which is mainly used to lift objects or adjust the height. It pushes the piston through the power of compressed air to achieve lifting movement. Therefore, the lifting cylinder can also be directly used to provide longitudinal movement function for the separation head 104, which is not costly and has good reliability. The linear motor lifting module is a lifting platform based on the principle of a linear motor, which is commonly used in automation equipment. It is mainly composed of a linear motor, a guide rail, a slider and a control system. In this embodiment, the linear motor lifting module can also be used as the lifting component 102 to provide the separation head 104 with a longitudinal movement function, which can further improve the motion control accuracy and efficiency of the separation head 104.

[0039] In one embodiment, a silicon steel sheet sample magnetic property measurement system is also provided, comprising an Epstein square ring measurement station and the above-mentioned silicon steel sheet separation mechanism.

The above-mentioned silicon steel sheet separation mechanism is arranged in the Epstein square circle measurement station 209, and is used to separate the thinner silicon steel sheet samples that have completed the measurement in the Epstein square circle.

[0040] The above-mentioned silicon steel sheet sample magnetic property measurement system, by adding a corresponding sample separation mechanism on the workbench of the Epstein square circle measurement station, generates external force through the introduced separation head to destroy the vacuum adsorption adhesion between the samples, reduces the friction between the samples, and greatly improves the success rate of the square circle magnetic property automated detection equipment for extracting thin samples, solves the difficulties and pain points of this type of equipment, reduces the frequency of manual intervention, and improves production efficiency.
