[0026] After magnetization, the magnetic material will pass through the dust removal mechanism 8, and the surface of the magnetic material will be cleaned by the conveying belt 801 and the blowing assembly 802 (blowing nozzle). Subsequently, the magnetic material will be transferred to the magnetic quantity detection mechanism 7 using the magnetic material transfer and handling mechanism 2, and its magnetic properties will be detected. The magnetic force detector 701 will monitor and record the data in real time.

[0027] The embodiment as a whole fully considers the automatic process, reduces manual operation and improves processing efficiency through components such as pneumatic clamping arms and mechanical arms.

The dust removal mechanism can ensure the cleanliness of the magnetic material during processing, thereby improving the quality of the product and reducing the defect rate.

[0028] Further, the first pneumatic clamping arm 601 and the second pneumatic clamping arm 604 are provided with a first guide seat 602 and a second guide seat 603, respectively. The first guide seat 602 and the second guide seat 603 are connected with the first translation assembly 605, and the first translation assembly 605 is fixedly arranged on the gantry 101.

[0029] The first pneumatic clamping arm 601 and the second pneumatic clamping arm 604 are used to clamp and move the magnetic material. The first pneumatic clamping arm 601 and the second pneumatic clamping arm 604 are respectively provided with guide seats (the first guide seat 602 and the second guide seat 603), which bear the functions of sliding and precise positioning. The pneumatic clamping arm is driven by air pressure and can accurately grasp the magnetic material and move it to a designated position by the first translation assembly 605. Through this structure, the handling assembly can efficiently move back and forth multiple times to complete the grasping, moving, and placing of the magnetic material.

[0030] Further, the first translation assembly 605 includes a roller-type linear guide rail, and the first guide seat 602 and the second guide seat 603 are respectively slidably arranged on the roller-type linear guide rail.

[0031] The roller-type linear guide rail is fixed on the gantry 101, and the horizontal movement of the handling assembly is realized by the sliding of the first translation assembly 605, ensuring the stability and precision of the assembly during movement.

[0032] Further, the second handling assembly includes a transfer handling arm 202, and the transfer handling arm 202 is connected with a second translation assembly 201. The second translation assembly 201 includes a ball-type linear guide rail.

[0034] When the magnetic material passes through the dust removal mechanism 8, it is first grabbed by the transfer arm 202 and moved along the ball-type linear guide rail to the magnetic quantity detection mechanism 7 through the second translation assembly 201. During the movement, the transfer arm 202 effectively controls the position through the control system to ensure that the magnetic material is accurately transferred to the detection position, avoiding positioning errors caused by errors.

[0035] Further, the dust removal mechanism 8 includes a mounting frame one and a conveyor belt 801 provided on the mounting frame. The conveyor belt 801 is provided with a blowing assembly 802 for dust removal of the magnetic material on both sides.

The blowing assembly 802 is arranged on both sides of the conveyor belt 801 for dust removal of the passing magnetic material. The air nozzles are arranged in a straight line, effectively covering the dust removal needs on both sides of the conveyor belt 801.

[0037] When the magnetic material moves to the dust removal area through the conveyor belt 801, the air nozzles of the blowing assembly 802 blow the dust on the surface of the magnetic material through the air flow. The air flow generated by the air nozzles effectively blows away the dust attached to the surface of the magnetic material, ensuring that the magnetic material is clean before entering the subsequent processing link. The arrangement of the air nozzles and the direction of the air flow are reasonably designed to make the air flow cover the width of the entire conveyor belt 801, thereby ensuring that all magnetic materials can be fully cleaned. Each air nozzle can be supplied with gas (such as compressed air), and the intensity of the air flow can be adjusted as needed to achieve the best dust removal effect.

[0038] Further, the magnetic quantity detection mechanism 7 includes a detection table 702 and a magnetic force detector 701 provided on the detection table 702. The end surface of the detection table 702 is provided with an anti-skid coating.

[0039] The magnetic quantity detection mechanism 7 is composed of a detection table 702 and a magnetic force detector 701 provided on the detection table 702. The end surface of the detection table 702 is provided with an anti-skid coating to ensure the stability of the magnetic material during detection.

[0040] When the magnetic material is transferred from the transfer arm 202 to the detection table 702, the magnetic force detector 701 first starts detection. The detector evaluates the magnetic properties of the magnetic material by sensing parameters such as the strength of the magnetic field. The magnetic force detector 701 uses sensors such as Hall elements and flux meters to capture magnetic field data and convert it into electrical signals that can be analyzed. The detected data is transmitted to the control system for processing to determine whether the magnetic material meets production standards.

[0041] Further, the unloading mechanism 5 comprises a five-axis transfer robot arm 501 with sensors and a robot arm controller 502 connected to the five-axis transfer robot arm 501.

[0042] The unloading mechanism 5 is composed of a five-axis transfer robot arm 501 equipped with sensors, a robot arm controller 502 connected to the robot arm, and a loading disc 102 for loading the magnetized products. The robot arm controller 502 is located on one side of the gantry 101 for easy control and operation. The five-axis transfer robot arm 501 is equipped with sensors that can monitor and identify the position and state of the magnetized products in real time. The sensor is an optical sensor that accurately obtains information about the target object.

[0043] The robot arm controller 502 calculates the motion trajectory of the robot arm based on the data sent by the sensor, moves the robot arm to the correct position, and grasps the magnetized product. The five-axis robot arm can move flexibly in multiple directions and angles, ensuring that it can grasp objects of different shapes and sizes. After grasping the product, the robot arm will transport it to the designated position on the loading disc 102 and place it there. The entire process is precisely controlled by the controller to ensure speed and accuracy.

[0044] Further, the push-pull assembly 304 comprises a cylinder and two push rods connected to the cylinder, each of the push rods corresponding to the connection of the track 302 on the first magnetizing seat 301 and the second magnetizing seat 401, and the track 302 is provided in the first magnetizing seat 301 and the second magnetizing seat 401.

[0045] The push-pull assembly 304 is mainly composed of a cylinder and two push rods. The cylinder is used to provide the power for the push-pull motion, and the push rods are connected to the cylinder and correspondingly connected to the tracks 302 on the first magnetizing seat 301 and the second magnetizing seat 401. The track 302 is provided in the first magnetizing seat 301 and the second magnetizing seat 401, providing guidance for the sliding of the push rods.

[0046] When the cylinder is filled with pressure gas, the piston of the cylinder will be pushed forward to generate linear motion. The motion of the cylinder is transmitted through the push rod, and under the pushing of the push rod, the first magnetizing seat 301 is pushed to the second magnetizing seat 401 or is pulled back. The motion trajectory of the push rod is guided by the track 302, and the two push rods can be relatively independently moved forward and backward on the respective tracks 302.
