Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to an automatic magnetization and feeding detection mechanism. Background Art

[0002] With the development of the current market, there are now higher and more stringent requirements for the production efficiency and quality level of magnetic materials. At present, the magnetization process of magnetic materials relies on manual feeding, which consumes a lot of manpower and increases production costs day by day.

[0003] Some companies have addressed this issue, such as publication number CN107658094B, which discloses an automatic magnetizing machine. This solution incorporates both a drive and magnetizing mechanism. While this approach largely addresses the inefficient magnetization process caused by manual placement of materials, it still requires ensuring accurate magnetization during the magnetization process, failing to meet the demands for both high efficiency and stable production.

[0004] Therefore, it is very necessary to develop an automatic magnetization and feeding detection mechanism, which can not only ensure the efficiency of magnetization, but also achieve the stability of feeding, greatly reducing the unnecessary loss of magnetized products during the working process. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model proposes an automatic magnetization and feeding detection mechanism with high automation, stable feeding and high magnetization efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an automatic magnetization and feeding detection mechanism, comprising a frame, a magnetization device and a feeding motor module are respectively provided at the upper and lower parts of the frame, a loading magnetization tray is provided in the magnetization device, a plurality of magnetization positioning grooves are provided at one end of the loading magnetization tray, and a driving connecting plate is connected to the other end, the lower part of the driving connecting plate is fixedly connected to the output end of the feeding motor module, when the magnetization positioning groove is located in the magnetization device to magnetize the magnetized product, it is set to the magnetization position, when the magnetization positioning groove is located at the loading and unloading position of the magnetized product, it is set to the loading position, the feeding motor module drives the loading magnetization tray to reciprocate between the magnetization position and the loading position through the driving connecting plate, thereby realizing the loading and unloading and automatic magnetization of the magnetized product, and detection optical fiber groups are provided on both sides of the magnetization positioning groove.

[0007] Based on the above, a magnetizing device and a feeding motor module are set on the frame, and the feeding motor module is used to realize the switching back and forth of the feeding magnetizing tray between the loading position and the magnetizing position, and automatically load and unload the materials, thereby realizing the automation of the loading and unloading of the mechanism; in addition, the feeding motor module is realized by an electric cylinder, which ensures the stability and reliability of the mechanism during the operation, and also ensures the accuracy of the magnetizing positioning groove, thereby ensuring a high magnetization quality; the use of the automated operation of the mechanism greatly improves the magnetization efficiency.

[0008] Furthermore, the magnetizing device includes a magnetizing head, which is composed of a magnetizing upper mold and a magnetizing lower mold. The magnetizing upper mold is driven to move up and down by a downward pressure magnetizing cylinder arranged on the frame, and then pressed or separated from the magnetizing lower mold. The loading magnetizing tray is fitted between the magnetizing upper mold and the magnetizing lower mold. A magnetizing coil is arranged in the magnetizing lower mold, and the magnetizing coil is externally connected to a capacitive high-voltage DC power supply.

[0009] Based on the above, the design of pressing and separating the magnetizing upper die and the magnetizing lower die is used to ensure that the mechanism has a stable magnetizing environment to ensure the magnetization quality. After the magnetized product is placed in the magnetizing positioning groove and the magnetizing upper die and the magnetizing lower die are pressed together, the peripheral capacitive high-voltage DC power supply discharges to the magnetizing coil. The peak value of the discharge pulse current can reach tens of thousands of amperes. This current pulse generates a strong magnetic field in the coil. This magnetic field magnetizes the magnetized product placed in the coil environment, thereby achieving magnetization. Its structure is simple and reliable, with good stability and high magnetization quality.

[0010] Furthermore, the feeding motor module includes an electric cylinder with a sliding block, the electric cylinder is provided with a guide rail that slides with the sliding block, the lower part of the sliding block is connected to the output end of the electric cylinder, the sliding block is connected to the drive connecting plate, and is driven by the electric cylinder. The loading and magnetizing tray reciprocates between the loading position and the magnetizing position, and a fiber optic detection limit device is provided on the side of the feeding motor module.

[0011] Based on the above, the characteristics of the electric cylinder movement are utilized to ensure the stability and reliability of the movement of the loading and magnetizing tray; the electric cylinder drives the sliding block, the sliding block drives the driving connecting plate, and the driving connecting plate drives the loading and magnetizing tray, ensuring the stability and reliability of loading and magnetization, while ensuring the magnetization accuracy and efficiency; in addition, the setting of the optical fiber detection limit device enables the magnetized product to accurately reach the magnetization position, ensuring the accuracy of magnetization.

[0012] Furthermore, the optical fiber detection limit device includes an optical fiber detection device and a limit block, the optical fiber detection device includes a magnetizing position optical fiber detection sensor and a loading position optical fiber detection sensor, and an induction plate is provided on the sliding block, and the induction plate follows the sliding block to move along the direction of the guide rail, and when the induction plate passes the magnetizing position optical fiber detection sensor, the feeding motor module stops, and the loading magnetizing tray is located in the magnetizing device for magnetization, and when the induction plate passes the loading position optical fiber detection sensor, the feeding motor module stops, and the loading magnetizing tray is located at the loading position for loading and unloading operations, and when the loading magnetizing tray is just at the loading position, the limit block just rests against the driving connecting plate.

[0013] Based on the above, the magnetizing position optical fiber detection sensor is used in conjunction with the loading position optical fiber detection sensor and the induction sheet. When the induction sheet blocks the magnetizing position optical fiber detection sensor or the loading position optical fiber detection sensor, it indicates that the loading magnetizing tray has reached the magnetizing position or the loading position, and the feeding motor module stops, and then the magnetizing or loading and unloading operations are carried out, ensuring the accuracy and efficiency of the magnetization. At the same time, the range of movement of the feeding motor module is limited, and the limit block ensures that the mechanism avoids collision accidents.

[0014] Furthermore, a loading position support plate is provided at the loading position, and the detection optical fiber group includes several groups of optical fiber shooting groups whose number is consistent with the magnetization positioning grooves, and the optical fiber shooting group includes a signal transmitting end and a signal receiving end, and the signal transmitting end and the signal receiving end are respectively provided on both sides of the loading position support plate. When the magnetization positioning groove on the loading magnetization tray is located at the loading position, the light emitted by the signal transmitting end passes through the magnetization positioning groove and is emitted to the signal receiving end.

[0015] Based on the above, the detection optical fiber group is set on both sides of the loading position support plate, and the optical fiber shooting group is used to detect the material placement in the magnetizing positioning slot, while ensuring that the magnetized product enters the magnetizing positioning slot in the correct posture, preventing the occurrence of collision.

[0016] Furthermore, the number of the magnetized positioning slots and the number of the optical fiber matching groups are both set to five.

[0017] Based on the above, multiple groups of magnetization positioning grooves are set for magnetization, which greatly improves the magnetization efficiency.

[0019] Based on the above, the guide plate is fixedly matched with the magnetizing upper die, and under the action of the guide column, the accuracy of the pressing of the magnetizing upper die and the magnetizing lower die is guaranteed, thereby ensuring that the magnetization accuracy is high enough; and the locking block is matched with the positioning groove. When the magnetized product is placed in the magnetizing positioning groove with deviation, the clearance between the locking block and the positioning groove is utilized to prevent the product from being crushed, and the convenience of mechanism installation is improved, and it also provides convenience for subsequent maintenance.

[0020] Furthermore, the downward-pressing magnetizing cylinder is connected to an external air source via a pressure regulating valve.

[0021] Based on the above, the pressure regulating valve is used to control the downward pressure of the magnetizing cylinder, which ensures the downward force and speed, and at the same time ensures the stability of magnetization, and the quality of the finished product output is well guaranteed.
