Description

Technical Field

[0001] The invention relates to the technical field of magnetizers, and in particular to a magnetizer capable of improving magnetization positioning accuracy. Background Art

[0002] A magnetizer is a device that can magnetize some special materials, so that the materials that originally do not have magnetism are magnetized. When in use, the special materials (such as magnetic materials) are usually placed in the magnetizing device, and the magnetic materials are taken out after magnetization. The existing common magnetizers have a complex overall structure, including a loading station, a magnetizing station, a magnetizing flux detection station, a surface magnetization station, a demagnetization station, and a unloading station. Each station is provided with a corresponding actuator. For example, the magnetizing station is equipped with a magnetizing box for the magnetic materials to enter for magnetization, and the demagnetization station is provided with a demagnetization cover to remove the magnetized magnetic materials that do not need to be magnetized. The magnetized parts are demagnetized; some existing simple magnetizing machines can also omit some workstations according to the processing requirements of magnetic materials. For example, when the magnetic materials do not need to be demagnetized, the demagnetization workstation is not required. However, the layout structure is still relatively complex and occupies a large space; in addition, during the magnetization process, the magnetic materials are conveyed to the magnetization box by a conveyor belt. The position accuracy of the magnetic materials in the magnetization box and the stability of the magnetic materials in the magnetization box have a great influence on the magnetization effect of the magnetic materials. The existing magnetizing machines can be further improved to limit the position accuracy of the magnetic materials in the magnetization box and ensure the stability of the magnetic materials, so as to meet the high-precision magnetization requirements.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0028] See also Figure 1-Figure 4 A simple magnetizing machine includes a frame 10, a magnetizing wire, a magnetizing detection wire, and a material transfer mechanism 40 connecting the magnetizing wire and the magnetizing detection wire. The frame 10 includes a machine table 11. The magnetizing wire, the magnetizing detection wire, and the material transfer mechanism are installed on the machine table 11. The magnetizing wire includes a magnetizing conveyor belt mechanism 20 and a magnetizing box 30 installed on the magnetizing conveyor belt mechanism 20. The magnetizing conveyor belt mechanism 20 conveys the magnetic material through the magnetizing box 30, and magnetizes the magnetic material through the magnetizing box 30. The material transfer mechanism 40 is used to transfer the magnetic material to the magnetizing box 30. 0 is located at the tail end of the magnetizing conveyor belt mechanism 20, which transfers the magnetized magnetic material to the magnetization detection line. The magnetization detection line includes a magnetization detection conveyor belt mechanism 50 and a magnetization detection mechanism 60 installed on the magnetization detection conveyor belt mechanism 50. The magnetization detection conveyor belt mechanism 50 is arranged in parallel with the magnetizing conveyor belt mechanism 20, and the magnetized magnetic material is conveyed through the magnetization detection mechanism 60. The magnetization detection mechanism 60 detects the magnetization strength of the magnetic material and selects unqualified magnetic material to prevent unqualified magnetic material from flowing into subsequent processing processes.

[0029] The machine 11 is configured as a hollow platform, and a control system is disposed inside the platform for controlling the actions of various mechanisms. Two installation slots 111 are provided in parallel on the top surface of the machine 11 for installing the magnetizing conveyor belt mechanism 20 and the magnetizing conveyor belt mechanism 50 .

[0030] The frame 10 further includes a protective cover 12 and a control panel 13. The protective cover 12 is set on the machine 11, and three sides are set as a normally closed double-door structure, and the fourth side is open for loading and unloading or maintenance operations. The loading and unloading of magnetic materials can be done by a robot or manually. The control panel 13 is connected to one side of the protective cover 12 and is connected to the control system in the machine 11 through wires to provide interface operations.

[0031] The magnetizing conveyor belt mechanism 20 and the magnetizing conveyor belt mechanism 50 are respectively installed in the installation groove 111 of the machine platform 11. The magnetizing conveyor belt mechanism 20 and the magnetizing conveyor belt mechanism 50 have opposite conveying directions and are connected to the material moving mechanism 40 to form a C-shaped conveying line.

[0032] The magnetized conveyor belt mechanism 20 includes a transmission wheel mounting frame 21, a transmission wheel 22, a conveyor belt 23, a clamp 24 and a conveying motor 25. The transmission wheel mounting frame 21 is arranged in the mounting groove 111 of the machine table 11. The transmission wheel mounting frame 21 includes a guide plate group and two mounting plate groups. The guide plate group is used to guide the conveyor belt 23, and has two guide plates 211 arranged in parallel in the upper and lower directions; the mounting plate groups are arranged at both ends of the guide plate group for mounting the transmission wheel 22, each mounting plate group has two mounting plates 212 arranged on both sides of the guide plate group, and each mounting plate 212 is provided with upper and lower rotating shaft holes 2121, so that each mounting plate group has two groups of rotating shaft holes 2121 distributed in the upper and lower directions for mounting the upper and lower transmission wheels 22 on each mounting plate group.

[0033] The transmission wheel mounting frame 21 further includes a support body 213, which is used to enhance the stability of the guide plate 211. The support body 213 is installed between the two guide plates 211, and the two guide plates 211 can be fixedly connected to the support body 213. Preferably, the support body 213 adopts a four-sided plate structure made of steel. Furthermore, a through hole 2131 is provided on the support body 213 to facilitate the installation of the magnetizing device. Preferably in this embodiment, the support bodies 213 are two arranged in parallel, and a through hole 2131 for installing the magnetizing device is formed between the two. The transmission wheel mounting frame 21 further includes a fixing plate group, which has fixing plates 214 arranged on both sides of the support body, and is fixed to the machine surface through the fixing plates 214, so that the entire transmission wheel mounting frame 21 is fixed on the machine. In this embodiment, the fixing plate 214 is L-shaped, including a longitudinal section and a transverse section vertically connected to one end of the longitudinal section. The longitudinal section is fixed to the support body 213, and the transverse section is fixed to the machine surface located on one side of the mounting groove 111. In this way, the lower end of the transmission wheel mounting frame 21 can be suspended in the mounting groove 111 to ensure that the conveyor belt 23 attached to the lower guide plate 211 is not hindered. The overall structure of the magnetized conveyor belt mechanism 20 is simplified and easy to install. There are four transmission wheels 22, which are installed at the four corners of the transmission wheel mounting frame 21, and the two ends of the rotating shaft of each transmission wheel 22 are respectively sleeved in the opposite rotating shaft holes 2121 of the two mounting plates.

[0034] The conveyor belt 23 is a rectangular endless belt connected end to end, which is sleeved on the driving wheel mounting frame 21 and fits on the upper and lower guide plates 211.

[0035] The clamp 24 is used to install the magnetic material. There are multiple clamps 24, which are installed at equal intervals on the outer surface of the conveyor belt 23. It can be understood that by setting the support body 213, the guide plate 211 can be fixed / supported, the stability of the guide plate 211 can be improved, and the stability of the clamp 24 on the conveyor belt 23 can be correspondingly improved.

[0036] Furthermore, the clamp 24 includes a seat body 241 and an elastic member 242 installed on the seat body 241. The seat body 241 is provided with a clamping groove for installing the magnetic material. The elastic member 242 is installed on one side of the clamping groove. After the magnetic material is installed in the clamping groove, the elastic member 242 supports the magnetic material, so that the magnetic material is installed stably.

[0037] The conveying motor 25 is used to drive the conveying belt 23 to move. The conveying motor 25 is installed on one of the mounting plates 212, and its output shaft is connected to the rotating shaft of a driving wheel 22, so that the conveying belt 23 is driven to move by the rotation of the output shaft of the conveying motor 25.

[0038] The magnetized conveyor belt mechanism 20 further includes a conveyor belt tension adjustment mechanism, including an adjusting bolt 26, which is used to adjust the horizontal position of the rotating shaft of the transmission wheel 22, so as to achieve the tension adjustment of the conveyor belt 23. Specifically, the rotating shaft hole 2121 is provided as a rectangular long hole in the horizontal direction, and the rotating shaft of the transmission wheel 21 can be installed in the rotating shaft hole 2121 through a bearing, and the adjusting bolt 26 is matched with the outer ring thread of the bearing, so that rotating the adjusting bolt 26 can drive the bearing to move and achieve tension adjustment. In addition, the rotating shaft of the transmission wheel 22 can also be set on a block that can move horizontally, and the block can be matched with the adjusting bolt 26 thread, and rotating the adjusting bolt 26 can also drive the block to move and achieve tension adjustment.

[0039] The magnetized 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 installed on the machine table 11 and is located on one side of the feeding end of the magnetized conveyor belt mechanism 20. It is used to detect whether the clamp 24 on the conveyor belt 23 has reached the feeding position. It includes a column 271 and a sensor 272 slidably installed on the column 271. When the clamp 24 of the conveyor belt 23 is transmitted to the feeding end of the magnetized conveyor belt mechanism 20, the sensor 272 detects the unloaded clamp 24, and the conveyor belt 23 stops rotating, and then the material is fed, 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, and is used to detect whether the magnetic material has been installed in the fixture 24. After the material is loaded, the magnetic material detection unit 28 detects the magnetic material and can start the transmission of the conveyor belt 23, and the conveyor belt 23 sends 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 here.

[0041] The magnetizing conveyor belt mechanism 20 further includes a magnetizing positioning mechanism for detecting the position of entering the magnetizing box 30. The magnetizing positioning mechanism includes a positioning detection unit 29, which is installed on the machine table 11 and located on one side of the magnetizing conveyor belt mechanism 20, and is used to sense the magnetic material transported to the preset position after magnetization. The positioning detection unit 29 can adopt the same structure as the fixture detection unit 27, which will not be described here.

[0042] The detection principle is as follows: since the clamps 24 are arranged at equal intervals on the conveyor belt 23, in order to ensure the accurate position of the magnetic material entering the magnetizing box 30, by setting the positioning detection unit 29 and the magnetic material detection unit 28 to simultaneously detect the magnetic materials on the two clamps 24 at both ends of the conveyor belt 23, it can be accurately determined that the middle clamp 24 between the two clamps 24 at both ends of the conveyor belt 23 will definitely correspond to the magnetizing box 30, and the position is accurate. That is, the position of the middle point is determined by sensing the positions of the two points at the same time. In order to improve the accuracy, in this embodiment, the conveying motor 25 adopts a servo motor. By using the servo motor, the movement accuracy is very high, the movement accuracy can reach 0.01mm, and the noise is very small, and the movement speed is also very fast. Preferably, the positioning detection unit 29 can be set on one side of the material-retrieving end of the magnetizing conveyor belt mechanism 20. When the positioning detection unit 29 detects the clamp 24 transported to the material-retrieving position after magnetization, the conveyor belt 23 stops, and the material transfer mechanism 40 can clamp the magnetic material in the clamp 24. Therefore, the positioning detection unit 29 also plays the role of material positioning and detection.

[0043] The magnetizing box 30 is used to magnetize the magnetic material and can be purchased from the market. The specific internal structure thereof is not described here. The magnetizing box 30 has a penetrating magnetizing channel 31 for the conveyor belt 23 to carry the magnetic material and send it into the magnetizing channel 31 from one end thereof, and the magnetic material stays 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 first installed on the machine platform 11, and then the supporting body 213 is installed at both ends of the magnetizing box 30 body, and then the guide plate group is installed, and the upper guide plate 211 is passed through the magnetizing channel 31, and then the installation plate group and other components are installed.

[0045] The magnetizing box 30 is disposed in the middle of the magnetizing conveyor belt mechanism 20 , and the lower half of the magnetizing box 30 penetrates into a through hole 2131 provided on the supporting body 213 .

[0046] See also Figure 5The material moving mechanism 40 includes a space guide frame 41 and a suction unit 42. The space guide frame 41 is used to drive the suction unit 42 to move in the space. The space guide frame 41 is more common, such as a gantry hanger structure, including a support rod, a crossbeam, a translation mechanism and a longitudinal movement mechanism. The support rod is set to two, which are parallelly set up on the machine platform 11 and are on both sides of the ends of the two mounting grooves 111. The two ends of the crossbeam are connected to the two support rods, correspondingly spanning above the tail end of the magnetizing conveyor belt mechanism 20 and the head end of the magnetizing conveyor belt mechanism 50. The translation mechanism is installed on the crossbeam, including a translation slide and a transverse movement driving member. The translation slide can be slidably installed on the crossbeam, and the translation slide is driven to slide along the crossbeam by the transverse movement driving member. The longitudinal movement mechanism is installed on the translation slide, including a longitudinal movement plate seat, a longitudinal slide installed on the longitudinal movement plate seat, and a longitudinal movement driving member. The longitudinal movement plate seat is fixed on the translation slide, and the longitudinal slide can be longitudinally slidably installed on the longitudinal movement plate seat. The longitudinal movement driving member is installed on the longitudinal movement plate seat to drive the longitudinal slide to slide longitudinally. The suction unit 42 can adopt a clamping cylinder structure, which is installed on the longitudinal slide. Through the guidance of the spatial guide frame 41, the magnetic material can be transported from the material taking station of the magnetization conveyor belt mechanism 20 to the material loading station of the magnetization conveyor belt mechanism 50.

[0047] The structure of the magnetization conveyor belt mechanism 50 is the same as that of the magnetization conveyor belt mechanism 20, and will not be elaborated here.

[0048] See also 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, including a magnetic detection box 61 and a rejection mechanism 62. The magnetic detection box 61 is a square frame structure, and has 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 the magnetic detection box 61 detects the magnetic material, the magnetized magnetic material is sent to the detection channel 611 through 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 at the rear of the magnetic detection box 61 to reject defective magnetic materials after magnetic flux detection. The rejection mechanism 62 includes a grabbing mechanism and a waste transfer mechanism. The grabbing mechanism is arranged on the magnetic detection conveyor belt mechanism 50. The structure of the grabbing mechanism is the same as that of the material transfer mechanism 40, which will not be described in detail here. The waste transfer mechanism includes a waste tray 63 and a pushing mechanism 64 that drives the waste tray 63 to move. The waste tray 63 is provided with multiple slots for placing different non-compliant magnetic materials. The pushing mechanism 64 adopts 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 than or exceeds the preset range of the system, the defective type of the magnetic material to be discarded will be detected and a rejection instruction will be generated. The grabbing mechanism will be started to remove the unqualified magnetic material from the clamp 24 and place it in 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 below the grasping mechanism, for detecting whether the clamp 24 on the conveyor belt 23 has 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 magnetic materials are placed in the waste tray 63. When the waste tray 63 is full of magnetic materials, the control system generates an alarm command to notify the staff to take them out.

[0053] When the magnetizing machine is used, the magnetic material is placed in the clamp 24 on the magnetizing conveyor belt mechanism 20. After the magnetic material detection unit 28 detects that the magnetic material is placed, the control system starts the conveying motor 25 to rotate and drive the conveyor belt 23 to rotate synchronously, and the magnetic material is conveyed to the magnetizing box 30. By relatively arranging the magnetizing detection device and the magnetizing positioning mechanism at the two ends of the magnetizing box 30, the magnetic material can be accurately controlled to stop at the center of the magnetizing box 30, and then the magnetizing box 30 is started to magnetize the magnetic material. The magnetized magnetic material is further conveyed to the end by the magnetizing conveyor belt mechanism 20. The part corresponds to the magnetizing positioning mechanism. The material moving mechanism 40 takes out the magnetic material on the magnetizing conveyor belt mechanism 20 through the clamping mechanism 43, and moves it to the end of the magnetic testing conveyor belt mechanism 50, and places the clamped magnetic material in the clamp 24 on the magnetic testing conveyor belt mechanism 50. After the magnetic material detection unit 28 detects that the magnetic material is put in, the magnetic testing 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 strength 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 magnetizing machine provided by the present invention is provided with a magnetizing conveyor belt mechanism coordinated with the magnetizing device, and the magnetizing conveyor belt mechanism has two guide plates arranged in parallel at the upper and lower sides; the conveyor belt is attached to the upper and lower guide plates; the stability and accuracy of the operation of the magnetic material, as well as the stability in the magnetizing box can be improved, and the magnetization detection mechanism and the magnetization positioning mechanism are respectively arranged on one side of the conveyor belt, and are relatively arranged with the magnetizing box as the midpoint, and the positions of the clamps at both ends of the conveyor belt are detected at the same time to determine the magnetizing position of the middle clamp, so that the accuracy of the magnetization position of the magnetic material conveyed in the magnetizing box can be ensured.
