Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a silicon steel sheet testing device. Background Technology

[0002] Silicon steel sheets, also known as silicon steel sheets, are electrical steels with a silicon content of 0.5%-4.5%. They are mainly used to manufacture the cores of equipment such as transformers and motors. Multiple slots are formed on the inner circumference of the silicon steel sheet. Current technology involves measuring dimensions with calipers and visually inspecting the integrity of the slots.

[0003] During the inspection process, workers place the product to be tested on the workbench, then measure the groove size with calipers, compare the measurement parameters, and reject the unqualified products.

[0004] Defects and shortcomings during the testing process:

[0005] ① Manual identification is difficult, and there are always omissions, leading to rework. ② During the inspection process, operators face the risk of dropping large raw materials, increasing the possibility of injury. ③ The use of calipers during inspection is unpredictable, resulting in inaccurate measurements. ④ The inspection work is labor-intensive, and the accuracy and pass rate of manual inspection cannot be guaranteed. ⑤ The inspection process requires repeated measurements and checks. Repeated steps result in slow inspection speed and extremely low work efficiency. ⑥ To improve speed, manual inspection can only perform random checks, making full inspection difficult.

[0041] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0042] like Figure 1 and Figure 2 The diagram shown is a structural schematic of the present invention, which provides a silicon steel sheet testing device, including a frame 100, a hoisting module 600 placed on the frame 100, a vision inspection module and a sample positioning module installed on the hoisting module 600, and a control unit connected to the vision inspection module and the sample positioning module to realize the automatic detection of silicon steel sheet sample 700.

[0043] like Figure 3As shown, the frame 100 is a cubic frame structure. The frame 100 has a clearance opening 101 for the installation of the hoisting module 600. Multiple rollers 105 and multiple feet 106 are provided at the bottom of the frame 100 to facilitate movement and positioning. For example, the rollers 105 and feet 106 can be positioned at the four corners of the frame 100. Door panel assemblies are provided on both sides of the frame 100.

[0044] like Figure 5 As shown, the lifting module 600 serves as a support for the vision inspection module and the sample positioning module. It can be directly placed on the frame 100, thus avoiding the need for a support platform on the frame 100 for mounting the vision inspection module and the sample positioning module, saving space and facilitating processing. The lifting module 600 includes a base plate 601, a panel 602 arranged on the upper end of the frame 100, and multiple connecting rods 603 connecting the panel 602 and the base plate 601. The panel 602 is a rectangular plate.

[0045] A vision inspection module is used to visually inspect whether there are defects in the slot 701 of the silicon steel sheet sample 700. It includes a vision inspection component 200 and a first drive component 300 that moves the vision inspection component 200 radially along the silicon steel sheet sample 700. Figure 4 As shown, the vision inspection assembly 200 includes a vertically arranged support plate 201, a camera connector 202 fixed to one side of the support plate 201 and arranged from top to bottom, a lens mounting plate 203 and a light source mounting plate 204, a vision inspection camera 205 mounted on the camera connector 202, a lens 206 mounted on the lens mounting plate 203, a light source 207 mounted on the light source mounting plate 204, and a reinforcing component fixed to the other side of the support plate 201. This reinforcing component is connected to the first driving component 300. The vision inspection camera 205 is a line-scan camera (area-scan camera) as used in the prior art, and the lens 206 is also a lens that works with the line-scan camera (area-scan camera). The vision inspection camera 205 compares the inspection data of the slot 701 of the silicon steel sheet sample 700 with the data of a standard part (standard size) preset by the control unit to determine whether the size of the slot 701 of the silicon steel sheet sample 700 meets the production requirements. This is prior art and will not be described in detail in this utility model.

[0046] The reinforcing component includes two reinforcing ribs 210 arranged symmetrically, with the upper reinforcing rib 210 connected to the first driving component 300. Preferably, the first driving component 300 adopts a ball screw type linear drive module (model SK8-L10-C-S100-BC-ZP40-D3) in the prior art, which will not be described in detail in this utility model. The reinforcing rib 210 is connected to the slide of the linear drive module via a connecting plate 210a.

[0047] To further optimize the implementation effect of this utility model, a first protective cover 208 is provided on the outer periphery of the visual inspection camera 205 and the lens 206, and a second protective cover 209 is provided on the outer periphery of the light source 207. The lower end of the first protective cover 208 is open, and the upper end of the second protective cover 209 is open.

[0048] like Figure 5 As shown, the sample positioning module is used to position the silicon steel sheet sample 700 and drive the silicon steel sheet sample 700 to rotate, so that the vision inspection module can inspect the multiple slots 701 in the circumferential direction of the silicon steel sheet sample 700. It includes a drive wheel mechanism 400, a driven wheel mechanism 500 disposed opposite to the drive wheel mechanism 400, and a second drive component 800 that drives the driven wheel mechanism 500 to move. The silicon steel sheet sample 700 is clamped between the drive wheel mechanism 400 and the driven wheel mechanism 500.

[0049] like Figure 2 As shown, the drive wheel mechanism 400 includes two drive wheel assemblies arranged opposite each other. Each drive wheel assembly includes a drive wheel 401 and a drive motor 402 that drives the drive wheel 401 to rotate. The drive motor 402 is mounted on the lower end of the panel 602 via a mounting base. The panel 602 has a through hole for the drive wheel 401 to pass through, and part of the drive wheel 401 extends above the panel 602.

[0050] like Figure 5 As shown, the driven wheel mechanism 500 includes a sliding mounting plate 501, a lifting connector 502 fixed on the sliding mounting plate 501, and two driven wheel assemblies mounted on the lifting connector 502. Each driven wheel assembly includes a mounting shaft 503 vertically fixed on the lifting connector 502 and driven wheels 504 rotatably mounted on the mounting shaft 503. The sliding mounting plate 501 is slidably connected to the base plate 601 and is drive-driven to the second drive component 800. Two grooves 602a are provided on the panel 602 for the two driven wheels 504 to pass through, wherein the driven wheels 504 are supported on the mounting shaft 503 by bearings. The second drive component 800 drives the sliding mounting plate 501 to move, thereby adjusting the distance between the driving wheel assembly and the driven wheel assembly to accommodate silicon steel sheet samples of different sizes. Preferably, the second drive component 800 is a rodless cylinder.

[0051] To facilitate the sliding connection between the sliding mounting plate 501 and the base plate 601, two guide rails 601a are arranged in parallel on the base plate 601, and two sliders 501a are provided on the sliding mounting plate 501 to cooperate with each guide rail 601a. ​​The sliding of the sliding mounting plate 501 on the base plate 601 is achieved through the cooperation between the sliders 501a and the guide rails 601a.

[0052] The working principle of this utility model is as follows:

[0053] The operator places the silicon steel sheet sample 700 on the panel 602, between the driven wheel mechanism 500 and the driving wheel mechanism 400. The second drive component 800 drives the driven wheel mechanism 500 to move towards the driving wheel mechanism 400, so that the driving wheel assembly and the driven wheel assembly clamp the silicon steel sheet sample 700. The first drive component 300 drives the vision inspection component 200 to move above the slot 701 of the silicon steel sheet sample 700 to inspect the slot 701 and transmit the data to the control unit. After the inspection of one slot 701 is completed, the drive motor 404 drives the driving wheel 401 to rotate, so as to rotate the silicon steel sheet sample 700, so that the vision inspection component 200 can inspect the next slot 701. This process is repeated until all slots 701 are inspected. The control unit compares the inspection data with the data of the preset standard part (standard size). If the product does not meet the requirements, a warning is issued, prompting the operator to reject the unqualified product.

[0054] In summary, this detection device can reduce manual labor intensity and improve detection efficiency and safety.

[0055] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
