Description

Technical Field

[0001] This utility model relates to the field of magnetic field detection technology, specifically a tooling for detecting the magnetization direction of a workpiece and eliminating abnormalities. Background Technology

[0002] In the field of magnetic field detection technology, magnetization direction detection is a crucial step in ensuring workpiece quality. Workpieces with abnormal magnetization directions may cause problems during subsequent processing or use. Therefore, how to efficiently detect and reject workpieces with abnormal magnetization directions is an urgent problem to be solved. Existing solutions mainly rely on manual inspection and magnetometer inspection. Manual inspection determines whether the magnetization direction of the workpiece is abnormal through visual inspection or touch. This method is inefficient and easily affected by human factors. Magnetometer inspection measures the magnetic field strength and direction of the workpiece to determine whether the magnetization direction is abnormal. While this method has high accuracy, it is slow and requires specialized equipment and personnel.

[0003] However, existing magnetization direction detection technologies have the following problems: First, manual inspection is inefficient and easily affected by human factors, failing to meet the requirements of large-scale production lines. Second, while magnetometer inspection offers high accuracy, it is slow and requires specialized equipment and personnel, resulting in high costs. Furthermore, existing technologies typically only detect the magnetization direction of a workpiece individually, unable to simultaneously detect it with other stations (such as appearance and dimensional stations). This not only reduces inspection efficiency but also increases the complexity and cost of the production line. Therefore, a fixture for detecting the magnetization direction of workpieces and rejecting abnormalities is proposed. Utility Model Content

[0006] As a further embodiment of this utility model: a loading station is provided on the outer side of the glass plate, and a sensor is provided in the connection area between the loading station and the glass plate.

[0008] As a further embodiment of this utility model: the number of rejection stations is two sets, and each set of rejection stations consists of an air blowing station and a material receiving station. One set of rejection stations is used to collect qualified workpieces, while the other set of rejection stations is used to collect unqualified workpieces.

[0009] As a further embodiment of this utility model: the number of rejection stations is multiple sets, each set of rejection stations consists of an air blowing station and a material receiving station, one set of rejection stations is used to collect qualified workpieces, while the other set of rejection stations is used to collect unqualified workpieces for various reasons.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This application adds a magnetization direction detection station to the outside of the glass disk and employs magnetic field detection technology. By measuring the magnetic field strength and direction of the workpiece, it determines whether the magnetization direction of the workpiece is abnormal. Compared with existing manual inspection methods, the detection results of this invention are more accurate and are not affected by human factors. At the same time, due to the use of automated inspection methods, it also avoids errors that may be caused by manual operation. Compared with existing large and medium-sized magnetometer inspection methods, the detection speed of this invention is faster, which can greatly improve the production line capacity. It can not only detect the magnetization direction of the workpiece, but also conduct simultaneous inspection with appearance inspection and dimensional inspection stations by designing the rotating station at the center of the glass disk.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 In this embodiment of the invention, a fixture for detecting the magnetization direction of a workpiece and rejecting abnormalities includes a base 1. A rotating station 2 is provided in the central area of ​​the top of the base 1. A glass disk 3, driven to rotate by the rotating station 2, is provided. The glass disk 3 has a diameter of 500 mm and a thickness of 10 mm. The surface of the glass disk 3 is smooth, wear-resistant, and can withstand a large load. The rotating station 2 is located at the center of the glass disk 3, realizing synchronous detection with the appearance inspection station 4 and the size inspection station 5, which greatly improves the detection efficiency. Furthermore, the rotation speed of the rotating station 2 when driving the glass disk 3 is not fast, which can prevent the workpiece from being damaged by the glass disk. Due to centrifugal force, the workpiece's position shifts. On the outer side of the glass disk 3, there are staggered visual inspection stations 4, dimensional inspection stations 5, and magnetization direction inspection stations 6. Since the positions of these stations are fixed, as the glass disk 3 rotates, the workpiece on it will sequentially pass through the areas covered by each station, ensuring that each station can complete the inspection of the workpiece. The magnetization direction inspection station 6 uses magnetic field detection technology; through the sensor on the station, the magnetization direction of the workpiece can be quickly and accurately detected. The sensor model is Honeywell. The HMC1022 has a measurement range of 0-1000 Gauss, a resolution of 0.1 Gauss, and a measurement accuracy of ±1%. The top of the base 1 is also equipped with multiple rejection stations, each consisting of an air blowing station 7 and a receiving station 8. The air blowing station 7 is connected to the controller, which is also connected to other detection stations. After receiving the combined detection data from each detection station, when a workpiece passes through the area of ​​the rejection station, the air blowing station 7 corresponding to the workpiece opens and generates a high-pressure airflow directed towards the corresponding receiving station 8, ensuring that the workpiece on the glass tray 3 enters the receiving station 8.

[0017] Please see Figure 1 In one embodiment, preferably, a loading station 9 is provided on the outer side of the glass plate 3. A sensor 10 is provided in the connection area between the loading station 9 and the glass plate 3. Further, the loading station 9 is composed of a conveyor belt, which can transport the workpiece to the upper surface of the glass plate 3. When the workpiece passes the sensor 10, the sensor 10 sends a signal, and the subsequent appearance inspection station 4 and size inspection station 5 take pictures in sequence.

[0018] Please see Figure 1 In one embodiment, preferably, the appearance inspection station 4 includes a thickness inspection station 4-1, a front and back inspection station 4-2, a short side inspection station 4-3, and a long side inspection station 4-4. The thickness inspection station 4-1, the front and back inspection station 4-2, the short side inspection station 4-3, and the long side inspection station 4-4 are all located on the outside of the glass plate 3. Further, the thickness inspection station 4-1, the front and back inspection station 4-2, the short side inspection station 4-3, and the long side inspection station 4-4 take pictures in sequence, upload them to the system, and identify whether the corresponding workpiece is qualified. Then, the data is transmitted to the controller, which controls the corresponding air blowing station 7 to work. This control process is existing technology and will not be described in detail here.

[0019] Please see Figure 1 In one embodiment, preferably, there are two sets of rejection stations. Each set of rejection stations consists of an air blowing station 7 and a material receiving station 8. One set of rejection stations is used to collect qualified workpieces, while the other set of rejection stations is used to collect unqualified workpieces. Furthermore, by using two sets of rejection stations, the workpieces can be divided into qualified and unqualified products, which is beneficial for the staff to plan the subsequent use of the workpieces.

[0020] Please see Figure 2 In another embodiment, preferably, the number of rejection stations is multiple sets, each set consisting of an air blowing station 7 and a material receiving station 8. One set of rejection stations is used to collect qualified workpieces, while the remaining sets of rejection stations are used to collect workpieces that are unqualified for various reasons. Furthermore, the rejection stations can be divided into multiple sets, one set of which is used to collect qualified workpieces, and the remaining rejection stations can be used to reject workpieces that are unqualified due to factors such as size defects, appearance defects, magnetization direction defects, etc.
