Description

Technical Field

[0001] This invention relates to the field of magnetizer technology, and in particular to a magnetizer that improves magnetization positioning accuracy. Background Technology

[0002] A magnetizer is a device that magnetizes special materials, transforming materials that were originally non-magnetic into magnetized ones. In use, the special material (such as a magnetic material) is typically placed inside the magnetizer, and after magnetization, the magnetic material is removed. Existing common magnetizers have a complex overall structure, including a loading station, a magnetization station, a magnetization flux detection station, a surface magnetization station, a demagnetization station, and a unloading station. Each station has a corresponding actuator; for example, the magnetization station has a magnetization box for the magnetic material to enter and be magnetized, and the demagnetization station has a demagnetization cover to remove unwanted magnetized areas from the material. The magnetized parts are then demagnetized. Some existing simple magnetizers can omit some stations depending on the processing requirements of the magnetic materials, such as when the magnetic materials do not need demagnetization. However, the layout and structure are still relatively complex and occupy a lot of space. In addition, during the magnetization process, the magnetic materials are conveyed to the magnetization box by a conveyor belt. The accuracy of the magnetic materials' position and stability within the magnetization box greatly affects the magnetization effect. Existing magnetizers can be further improved to ensure the accuracy of the magnetic materials' position and stability within the magnetization box in order to meet the requirements of high-precision magnetization. Summary of the Invention

[0003] In view of the above, it is necessary for the present invention to provide a simple magnetizer that can improve the magnetization positioning accuracy, improve the positional accuracy and stability of the magnetic material in the magnetization box, and meet the needs of high-precision industries.

[0004] A magnetizer for improving magnetization positioning accuracy includes a machine base, a magnetization conveyor belt mechanism mounted on the machine base, and a magnetization box mounted on the magnetization conveyor belt mechanism.

[0005] The magnetized conveyor belt mechanism includes a drive wheel mounting frame, a drive wheel, a conveyor belt, and a clamp. The drive wheel mounting frame includes a guide plate assembly and two mounting plate assemblies. The guide plate assembly is used to guide the conveyor belt and has two guide plates arranged parallel to each other vertically. The mounting plate assemblies are located at both ends of the guide plate assembly and are used to mount the drive wheel.

[0006] The conveyor belt is fitted onto the drive wheel mounting frame and is attached to the upper and lower guide plates;

[0007] The clamps are of several kinds and are fixed to the outer surface of the conveyor belt at equal intervals;

[0008] The magnetizing conveyor belt mechanism also includes a magnetization detection mechanism and a magnetization positioning mechanism, which are respectively set on one side of the conveyor belt and are positioned opposite each other with the magnetization box as the midpoint. They are used to simultaneously detect the positions of the clamps at both ends of the conveyor belt to determine the magnetization position of the clamp in the middle.

[0009] Furthermore, the transmission wheel mounting frame includes a support body, with two support bodies sandwiched between the upper and lower guide plates. A through hole is formed between the two support bodies to accommodate the magnetizing box, and the magnetizing box has a magnetizing channel for the upper guide plate to pass through.

[0010] Furthermore, the machine tool is provided with an installation slot for installing a magnetized conveyor belt mechanism. The transmission wheel mounting frame includes a fixed plate assembly, which has fixed plates arranged opposite to each other on both sides of the support body. The fixed plate includes a longitudinal extension and a transverse extension vertically connected to one end of the longitudinal extension. The longitudinal extension is fixed to the support body, and the transverse extension is fixed to the machine tool surface located on one side of the installation slot, so that the lower end of the transmission wheel mounting frame is suspended in the installation slot.

[0011] Furthermore, each of the mounting plate assemblies has two mounting plates disposed opposite each other on both sides of the guide plate assembly. Each mounting plate has two shaft holes, one upper and one lower, for mounting the shaft of the transmission wheel. The shaft holes are rectangular elongated holes in the horizontal direction. The transmission wheel mounting bracket includes adjusting bolts for adjusting the position of the shaft of the transmission wheel in the horizontal direction.

[0012] Furthermore, the magnetization detection mechanism includes a clamp detection unit, which is installed on the machine base and located on one side of the loading end of the magnetized conveyor belt mechanism. It is used to detect whether the clamp on the conveyor belt has reached the loading position, and includes a column and a sensor that is slidably installed on the column.

[0013] Furthermore, the magnetization detection mechanism includes a magnetic material detection unit, which is installed on one side of the feeding end of the magnetization conveyor belt mechanism and is arranged opposite to the fixture detection unit, for detecting whether magnetic material has been installed in the fixture.

[0014] Furthermore, the magnetizer includes a magnetic detection conveyor belt mechanism, which has the same structure as the magnetizing conveyor belt mechanism. Two mounting slots are opened parallel to each other on the top surface of the machine for mounting the magnetizing conveyor belt mechanism and the magnetic detection conveyor belt mechanism. The material transfer mechanism is located at the tail end of the magnetizing conveyor belt mechanism, which transfers the magnetized magnetic material to the head end of the magnetic detection conveyor belt mechanism.

[0015] Furthermore, the magnetizer includes a magnetization mechanism mounted on the magnetization conveyor belt mechanism. The magnetization mechanism includes a magnetic detection box, which is installed at the through hole formed between the two supporting bodies. The guide plate on the upper side of the magnetization conveyor belt mechanism passes through the detection channel.

[0016] Furthermore, the magnetic detection mechanism includes a rejection mechanism installed at the rear of the magnetic detection box. The rejection mechanism includes a waste material transfer mechanism, which includes a waste material tray and a pushing mechanism for driving the waste material tray to move. The waste material tray is provided with multiple slots for placing different non-compliant magnetic materials.

[0017] Furthermore, the magnetic conveyor belt mechanism is provided with magnetic detection mechanisms on both sides to detect whether the clamps on the conveyor belt have moved into place and whether defective magnetic materials have been removed. The waste material transfer mechanism is provided with magnetic material detection units on both sides to detect whether magnetic materials are placed in the waste material tray.

[0018] Compared to existing technologies, this invention provides a magnetizer that improves magnetization positioning accuracy. By incorporating a magnetization conveyor belt mechanism that works in conjunction with the magnetization device, the conveyor belt mechanism has two guide plates arranged parallel to each other. The conveyor belt adheres to the upper and lower guide plates, improving the stability and accuracy of the magnetic material's movement, as well as its stability within the magnetization box. Furthermore, a magnetization detection mechanism and a magnetization positioning mechanism are respectively positioned on one side of the conveyor belt, relative to each other with the magnetization box as the midpoint. Simultaneously, the positions of the clamps at both ends of the conveyor belt are detected to determine the magnetization position of the middle clamp, thus ensuring the accuracy of the magnetization position of the magnetic material conveyed within the magnetization box.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-4 A simple magnetizing machine includes a frame 10, a magnetizing wire, a detection wire, and a material transfer mechanism 40 connecting the magnetizing wire and the detection wire. The frame 10 includes a machine base 11, on which the magnetizing wire, detection wire, and material transfer mechanism are mounted. The magnetizing wire includes a magnetizing conveyor belt mechanism 20 and a magnetizing box 30 mounted on the magnetizing conveyor belt mechanism 20. The magnetizing conveyor belt mechanism 20 conveys the magnetic material through the magnetizing box 30, where the magnetic material is magnetized. The material transfer mechanism 40... 0 is located at the tail end of the magnetizing conveyor belt mechanism 20, which transfers the magnetized magnetic material to the detection line. The detection line includes a detection conveyor belt mechanism 50 and a detection mechanism 60 installed on the detection conveyor belt mechanism 50. The detection conveyor belt mechanism 50 is arranged parallel to the magnetizing conveyor belt mechanism 20. The magnetized magnetic material is conveyed through the detection mechanism 60. The detection mechanism 60 detects the magnetization intensity of the magnetic material and picks out unqualified magnetic materials to prevent unqualified magnetic materials from flowing into subsequent processing processes.

[0029] The machine 11 is a hollow platform with a control system inside to control the actions of each mechanism. Two mounting slots 111 are opened parallel to each other on the top surface of the machine 11 for mounting the magnetizing conveyor belt mechanism 20 and the magnetic detection conveyor belt mechanism 50.

[0030] The frame 10 further includes a protective cover 12 and a control panel 13. The protective cover 12 is mounted on the machine base 11 and has a normally closed double-door structure on three sides, while the fourth side is open for loading, unloading, or maintenance operations. The loading and unloading of magnetic materials can be done using a robotic arm or manually. The control panel 13 is connected to one side of the protective cover 12 and is connected to the control system inside the machine base 11 via wires to provide an interface for operation.

[0031] The magnetizing conveyor belt mechanism 20 and the magnetic detection conveyor belt mechanism 50 are respectively installed in the mounting slot 111 of the machine base 11. The magnetizing conveyor belt mechanism 20 and the magnetic detection conveyor belt mechanism 50 have opposite conveying directions and are connected to the material transfer mechanism 40 to form a C-shaped conveyor line.

[0032] The magnetized conveyor belt mechanism 20 includes a drive wheel mounting frame 21, drive wheels 22, a conveyor belt 23, a clamp 24, and a conveyor motor 25. The drive wheel mounting frame 21 is set in the mounting slot 111 of the machine base 11. The drive wheel mounting frame 21 includes a guide plate assembly and two mounting plate assemblies. The guide plate assembly is used to guide the conveyor belt 23 and has two guide plates 211 arranged parallel to each other. The mounting plate assemblies are set at both ends of the guide plate assembly and are used to install the drive wheels 22. Each mounting plate assembly has two mounting plates 212 arranged opposite to each other on both sides of the guide plate assembly. Each mounting plate 212 has two sets of rotating shaft holes 2121, one above and one below, so that each mounting plate assembly has two sets of rotating shaft holes 2121 distributed vertically to install the upper and lower drive wheels 22 on each mounting plate assembly.

[0033] The drive wheel mounting bracket 21 further includes a support body 213 for enhancing the stability of the guide plate 211. The support body 213 is installed between two guide plates 211, allowing the two guide plates 211 to be fixedly connected to the support body 213. Preferably, the support body 213 is a quadrilateral plate structure made of steel. Furthermore, the support body 213 has a through hole 2131 for mounting the magnetizing device. In this embodiment, preferably, there are two support bodies 213 arranged side by side, with a through hole 2131 formed between them for mounting the magnetizing device. The drive wheel mounting frame 21 further includes a fixing plate assembly, which has fixing plates 214 disposed opposite to each other on both sides of the support body. The fixing plates 214 are fixed to the machine surface, thereby fixing the entire drive wheel mounting frame 21 to the machine platform. In this embodiment, the fixing plate 214 is L-shaped, including a longitudinal extension and a transverse extension vertically connected to one end of the longitudinal extension. The longitudinal extension is fixed to the support body 213, and the transverse extension is fixed to the machine platform surface located on one side of the mounting groove 111. This allows the lower end of the drive wheel mounting frame 21 to be suspended in the mounting groove 111, ensuring that the section of the conveyor belt 23 attached to the lower guide plate 211 runs unimpeded. This not only simplifies the structure of the magnetized conveyor belt mechanism 20 but also facilitates installation. There are four drive wheels 22, which are installed at the four corners of the drive wheel mounting frame 21. The two ends of the shaft of each drive wheel 22 are respectively fitted into the opposite shaft holes 2121 of the two mounting plates.

[0034] The conveyor belt 23 is a rectangular loop belt with its ends connected. It is fitted onto the drive wheel mounting frame 21 and adheres to the upper and lower guide plates 211.

[0035] Clamps 24 are used to mount magnetic materials. Multiple clamps 24 are installed at equal intervals on the outer surface of the conveyor belt 23. Understandably, by setting the support body 213, the guide plate 211 can be fixed / supported, improving the stability of the guide plate 211, and correspondingly improving the stability of the clamps 24 on the conveyor belt 23.

[0036] Furthermore, the clamp 24 includes a base 241 and an elastic member 242 mounted on the base 241. The base 241 has a clamping groove for installing magnetic materials. The elastic member 242 is mounted on one side of the clamping groove. After the magnetic material is installed into the clamping groove, the elastic member 242 holds the magnetic material, making the installation of the magnetic material stable.

[0037] The conveyor motor 25 is used to drive the conveyor belt 23 to move. The conveyor motor 25 is mounted on one of the mounting plates 212, and its output shaft is connected to the rotating shaft of a transmission wheel 22. Thus, the output shaft of the conveyor motor 25 rotates, driving the conveyor belt 23 to move.

[0038] The magnetized conveyor belt mechanism 20 further includes a conveyor belt tension adjustment mechanism, including an adjusting bolt 26, used to adjust the horizontal position of the drive wheel 22's shaft, thereby adjusting the tension of the conveyor belt 23. Specifically, the shaft hole 2121 is a horizontally oriented rectangular slot. The drive wheel 21's shaft can be mounted in the shaft hole 2121 via a bearing. The adjusting bolt 26 engages with the outer ring thread of the bearing, so rotating the adjusting bolt 26 moves the bearing, thus adjusting the tension. Alternatively, the drive wheel 22's shaft can also be mounted on a horizontally movable block. The block engages with the adjusting bolt 26 via a thread, so rotating the adjusting bolt 26 also moves the block, adjusting the tension.

[0039] The magnetizing conveyor belt mechanism 20 further includes a magnetization detection mechanism, which includes a clamp detection unit 27 and a magnetic material detection unit 28. The clamp detection unit 27 is mounted on the machine base 11 and located on one side of the loading end of the magnetizing conveyor belt mechanism 20. It is used to detect whether the clamp 24 on the conveyor belt 23 has reached the loading position. It includes a column 271 and a sensor 272 slidably mounted on the column 271. When the clamp 24 on the conveyor belt 23 is conveyed to the loading end of the magnetizing conveyor belt mechanism 20, the sensor 272 detects that the clamp 24 is empty, then the conveyor belt 23 stops rotating, and then the material is loaded, that is, the magnetic material is installed on the clamp 24.

[0040] The magnetic material detection unit 28 is installed on one side of the feeding end of the magnetizing conveyor belt mechanism 20, and can be arranged opposite to the fixture detection unit 27. It is used to detect whether magnetic material has been installed in the fixture 24. After feeding, if the magnetic material detection unit 28 detects the magnetic material, it can start the conveyor belt 23 to drive the magnetic material into the magnetizing box 30. The magnetic material detection unit 28 can adopt the same structure as the fixture detection unit 27, which will not be described further here.

[0041] The magnetizing conveyor belt mechanism 20 further includes a magnetizing positioning mechanism for detecting the position of the material entering the magnetizing box 30. The magnetizing positioning mechanism includes a positioning detection unit 29, which is mounted on the machine base 11 and located on one side of the magnetizing conveyor belt mechanism 20, and is used to sense the magnetic material that has been magnetized and conveyed to the preset position. The positioning detection unit 29 may adopt the same structure as the fixture detection unit 27, which will not be described further here.

[0042] The detection principle is as follows: Since clamps 24 are evenly spaced on the conveyor belt 23, to ensure the accurate positioning of the magnetic material entering the magnetization box 30, the positioning detection unit 29 and the magnetic material detection unit 28 simultaneously detect the magnetic material on the two clamps 24 at both ends of the conveyor belt 23. This allows for precise determination that the clamp 24 located between the two clamps 24 at both ends of the conveyor belt 23 will correspond precisely to the magnetization box 30. In other words, the position of the midpoint is determined by simultaneously sensing the positions of two points. To improve accuracy, in this embodiment, the conveyor motor 25 is a servo motor. The use of a servo motor results in very high motion accuracy, reaching 0.01mm, with very low noise and rapid movement. Preferably, the positioning detection unit 29 can be located on one side of the material-picking end of the magnetization conveyor belt mechanism 20. When the positioning detection unit 29 detects the clamp 24 that has been conveyed to the picking position after magnetization, the conveyor belt 23 stops, allowing the material transfer mechanism 40 to pick up the magnetic material from the clamp 24. Therefore, the positioning and detection unit 29 also serves as a material picking and positioning unit and a detection unit.

[0043] The magnetizing box 30 is used to magnetize the magnetic material. It can be purchased from the market. Its internal structure will not be described here. The magnetizing box 30 has a through magnetizing channel 31, so that the conveyor belt 23 can carry the magnetic material into the magnetizing channel 31 from one end and keep it in the magnetizing channel 31 for a preset magnetizing time. After the magnetizing time is sufficient, the magnetic material is sent out from the other end of the magnetizing channel 31.

[0044] When installing the magnetizing box 30, the magnetizing box 30 can be installed on the machine base 11 first, then the support body 213 can be installed at both ends of the magnetizing box 30 body, then the guide plate assembly can be installed, the upper guide plate 211 can be passed through the magnetizing channel 31, and then the mounting plate assembly and other components can be installed.

[0045] The magnetizing box 30 is located in the middle of the magnetizing conveyor belt mechanism 20, and the lower half of the magnetizing box 30 is inserted into the support body 213, which has a through hole 2131.

[0046] Please see Figure 5The material transfer mechanism 40 includes a spatial guide frame 41 and a suction unit 42. The spatial guide frame 41 is used to drive the suction unit 42 to move in space. The spatial guide frame 41 is quite common, such as a gantry crane structure, including support rods, a crossbeam, a translation mechanism, and a longitudinal mechanism. The support rods are set as two, which are set parallel to each other on the machine base 11 and are located on both sides of the ends of the two mounting slots 111. The two ends of the crossbeam are connected to the two support rods and cross over the tail end of the magnetizing conveyor belt mechanism 20 and the head end of the magnetic detection conveyor belt mechanism 50. The translation mechanism is installed on the crossbeam and includes a translation slide plate and a transverse drive component. The translation slide plate is slidably installed on the crossbeam and is driven to slide along the crossbeam by the transverse drive component. The longitudinal mechanism is installed on the translation slide plate and includes a longitudinal plate base, a longitudinal slide plate installed on the longitudinal plate base, and a longitudinal drive component. The longitudinal plate base is fixed on the translation slide plate, the longitudinal slide plate is slidably installed on the longitudinal plate base, and the longitudinal drive component is installed on the longitudinal plate base to drive the longitudinal slide plate to slide longitudinally. The suction unit 42 can adopt a gripper cylinder structure, which is installed on the longitudinal slide plate. Through the guidance of the spatial guide frame 41, the magnetic material can be transported from the material picking station of the magnetizing conveyor belt mechanism 20 to the material loading station of the magnetic detection conveyor belt mechanism 50.

[0047] The magnetic detection conveyor belt mechanism 50 has the same structure as the magnetizing conveyor belt mechanism 20, and will not be described here.

[0048] Please see Figure 6 The magnetic detection mechanism 60 is installed on the magnetic detection conveyor belt mechanism 50 and is used to detect the magnetization amount of the magnetized magnetic material. It includes a magnetic detection box 61 and a rejection mechanism 62. The magnetic detection box 61 has a square frame structure and a detection channel 611. Similarly, the magnetic detection box 61 is installed at the through hole 2131 formed by the two supporting bodies 213, and the upper guide plate 211 of the magnetic detection conveyor belt mechanism 50 passes through the detection channel 611. When detecting the magnetic material, the magnetized magnetic material is fed into the detection channel 611 via the conveyor belt 23 for magnetic detection. At this time, the conveyor belt 23 stops moving, and the center of the magnetic detection box 61 corresponds to the center of the magnetic material in the clamp 24 on the magnetic detection conveyor belt mechanism 50.

[0049] The rejection mechanism 62 is installed behind the magnetic detection box 61 to reject defective magnetic materials after magnetic flux detection. The rejection mechanism 62 includes a gripping mechanism and a waste material transfer mechanism. The gripping mechanism is located on the magnetic detection conveyor belt mechanism 50, and its structure is the same as that of the material transfer mechanism 40, so it will not be described in detail here. The waste material transfer mechanism includes a waste tray 63 and a pushing mechanism 64 that drives the waste tray 63 to move. The waste tray 63 has multiple slots for placing different non-compliant magnetic materials. The pushing mechanism 64 uses a motor-screw mechanism.

[0050] Specifically, the strength of the magnetic field is detected by the current generated when the magnetized magnetic material passes through the magnetic detection box 61. When the current is lower or higher than the preset range of the system, the defective type of the magnetic material to be rejected will be detected and a rejection instruction will be generated. The gripping and moving mechanism will be activated to remove the unqualified magnetic material from the fixture 24 and place it into different slots on the waste tray 63 according to the generated rejection instruction.

[0051] Similarly, magnetic detection mechanisms are provided on both sides of the magnetic detection conveyor belt mechanism 50, corresponding to the gripping mechanism below, to detect whether the clamps 24 on the conveyor belt 23 have moved into place and whether defective magnetic materials have been removed.

[0052] Furthermore, magnetic material detection units 28 are installed on both sides of the waste transfer mechanism to detect whether there is magnetic material in the waste tray 63. When the waste tray 63 is full of magnetic material, the control system generates an alarm command to notify the staff to remove it.

[0053] When using the aforementioned magnetizer, the magnetic material is placed in the clamp 24 on the magnetizing conveyor belt mechanism 20. After the magnetic material detection unit 28 detects the placement of the magnetic material, the control system starts the conveyor motor 25 to rotate, driving the conveyor belt 23 to rotate synchronously, thus conveying the magnetic material to the magnetizing box 30. By setting the magnetization detection device and the magnetization positioning mechanism opposite to each other at both ends of the magnetizing box 30, the magnetic material can be precisely controlled to stop at the center of the magnetizing box 30. Then, the magnetizing box 30 starts to magnetize the magnetic material. The magnetized magnetic material is further conveyed to the end by the magnetizing conveyor belt mechanism 20. Corresponding to the magnetization positioning mechanism, the material transfer mechanism 40 takes out the magnetic material from the magnetization conveyor belt mechanism 20 through the clamping mechanism 43 and moves it to the end of the magnetic detection conveyor belt mechanism 50. The clamped magnetic material is placed in the clamp 24 on the magnetic detection conveyor belt mechanism 50. After the magnetic material is detected by the magnetic material detection unit 28, the magnetic detection conveyor belt mechanism 50 moves the magnetic material. When the magnetic material passes through the magnetic detection box 61, the magnetic detection box 61 can measure the magnetization intensity of the magnetic material and determine whether it is qualified. Unqualified magnetic materials will be taken out by the rejection mechanism 62 and placed in the waste tray 63.

[0054] In summary, the magnetizer provided by this invention, by setting a magnetizing conveyor belt mechanism that cooperates with the magnetizing device, has two guide plates arranged parallel to each other at the top and bottom. The conveyor belt adheres to the upper and lower guide plates, which can improve the stability and accuracy of the magnetic material's operation, as well as its stability within the magnetizing box. Furthermore, by setting a magnetization detection mechanism and a magnetization positioning mechanism on one side of the conveyor belt and positioning them relative to each other with the magnetizing box as the midpoint, the position of the clamps at both ends of the conveyor belt is detected to determine the magnetization position of the clamp in the middle. This ensures the accuracy of the magnetization position of the magnetic material conveyed in the magnetizing box.
