Description

Technical Field

[0001] This utility model belongs to the field of ferrite magnetic sheet detection technology, and more specifically, it relates to a ferrite magnetic sheet detection device. Background Technology

[0002] Magnetic ceramics mainly refer to ferrite ceramics, which are composite oxides with iron oxide and other iron group or rare earth group oxides as the main components. Ferrites are mostly semiconductors, with resistivity much higher than that of general metallic magnetic materials, and have the advantage of low eddy current loss. They have been widely used in high-frequency and microwave technology fields, such as radar technology, communication technology, space technology, and electronic computers.

[0003] Based on the above, the following problems were found: After the ferrite magnetic sheet is produced, it is usually necessary to test the performance of the ferrite magnetic sheet. Most existing equipment tests the conductivity of the ferrite, but there is no testing agency to test its magnetic properties. Testing whether the magnetic properties of the ferrite are qualified is also a very important part of the testing process.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a ferrite magnetic sheet detection device in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a ferrite magnetic sheet testing device, which solves the problem that most existing devices only test the conductivity of ferrites, and there is no testing mechanism to test their magnetic properties.

[0010] Furthermore, the material distribution mechanism includes three grading plates arranged vertically and parallel to each other, with corresponding sliders fixed at both ends of the three grading plates. The fifth support rod has three vertically spaced sliding grooves through its middle section, and the sliders are slidably connected to the corresponding sliding grooves.

[0011] Furthermore, both ends of the slider are threadedly connected with limit bolts, a second guide plate is fixed to one side of the top grading plate, and a baffle plate is fixed to the top of the bottom end of the second guide plate.

[0012] Furthermore, a first guide plate is fixed to one side of the grading plate in the middle, a fourth support rod is fixed to one end of the first support rod, a collection box is fixed to the top of the fourth support rod, and the bottom end of the first guide plate is located directly above the collection box.

[0013] Furthermore, the height of the actuating plate is equal to the height of the slide groove, and the length of the actuating plate is adapted to the distance between the fifth support rod and the second rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the ferrite magnetic sheet to be tested is placed sequentially on the top of the conveyor belt. The first servo motor drives the first rotating shaft to rotate, which in turn drives the active roller to rotate and transport the magnetic sheet. Two electromagnets are energized, and a magnetic field is formed between the two electromagnets.

[0016] 2. In this invention, the ferrite magnetic sheets are positioned at different horizontal heights based on the influence of magnetic force and gravity. The positions of the three grading plates are adjusted according to the different specifications of the ferrite magnetic sheets. The top grading plate is used to remove magnetic sheets with excessive magnetic force. The baffle plate collects the magnetic sheets with excessive magnetic force from the top of the second guide plate. Magnetic sheets with qualified magnetic force fall from the middle grading plate into the first guide plate and finally into the collection box. Magnetic sheets with weak magnetic force fall onto the bottom grading plate, thereby achieving the effect of automatic screening after detection. Attached Figure Description

A feeding mechanism is located in the middle of one side of the first support rod 1, a third support rod 8 is fixed to the middle of the other side of the first support rod 1, an electromagnet 9 is fixed to one side of the third support rod 8, and fifth support rods 15 are fixed to both sides of the first support rod 1. A material distribution mechanism is movably installed in the middle of the two fifth support rods 15. By placing the ferrite magnetic sheets to be tested sequentially on the top of the conveyor belt 7, the first servo motor 3 drives the first rotating shaft 4 to rotate, which in turn drives the active roller 5 to rotate and transport the magnetic sheets.

[0028] There are two electromagnets 9, which are located above and below the conveyor belt 7 respectively. When the two electromagnets 9 are energized, a magnetic field is formed between them. The ferrite magnetic sheet is subjected to the magnetic field force and moves upward. Due to the influence of magnetic force and its own gravity, the position of the ferrite magnetic sheet is at different horizontal heights.

[0029] The feeding mechanism includes a second servo motor 10, which is fixed to the middle of one side of the first support rod 1. A second rotating shaft 11 is fixed to the top of the second servo motor 10, and a toggle plate 12 is fixed to the outer wall of the second rotating shaft 11. The toggle plate 12 is located above the conveyor belt 7. The second rotating shaft 11 is driven to rotate by the second servo motor 10, which toggle the ferrite magnetic sheet suspended between the two electromagnets 9 and move it to the top of the grading plate 17.

[0030] The material sorting mechanism includes three graded plates (17) arranged vertically and horizontally. Each of the three graded plates 17 has a corresponding slider 18 fixed at both ends. The fifth support rod 15 has three vertically spaced sliding grooves 16 through its middle section. The slider 18 is slidably connected to the sliding grooves 16. The position of the three graded plates 17 is adjusted according to the different specifications of ferrite magnetic sheets. The slider 18 is moved in the sliding grooves 16 to adjust the position.

[0031] Both ends of the slider 18 are threadedly connected to limit bolts 19. A second guide plate 21 is fixed to one side of the top grading plate 17. A baffle plate 22 is fixed to the top of the bottom of the second guide plate 21. After adjustment, the limit bolts 19 are rotated to limit the movement. The top grading plate 17 is used to remove magnetic sheets with excessive magnetic force. The baffle plate 22 collects the magnetic sheets with excessive magnetic force at the top of the second guide plate 21.

[0032] The first guide plate 20 is fixed to one side of the grading plate 17 in the middle, and the fourth support rod 13 is fixed to one end of the first support rod 1. The collection box 14 is fixed to the top of the fourth support rod 13. The bottom of the first guide plate 20 is located directly above the collection box 14. Magnetic sheets with qualified magnetic force fall from the grading plate 17 in the middle into the first guide plate 20 and finally into the collection box 14.

[0033] The height of the actuating plate 12 is equal to the height of the slide 16, and the length of the actuating plate 12 is matched with the distance between the fifth support rod 15 and the second rotating shaft 11. The second servo motor 10 drives the second rotating shaft 11 to rotate, so that the actuating plate 12 can touch any height of the three grading plates 17. At the same time, the length of the actuating plate 12 is sufficient to move the suspended magnetic sheet above the grading plate 17.

[0034] Example 2:

[0035] This utility model provides a ferrite magnetic sheet detection device, including a first support rod 1, a second support rod 2 fixed to one end of the first support rod 1, a first servo motor 3 fixed to the top of the second support rod 2, and a first rotating shaft 4 fixed to the power output end of the first servo motor 3. The device is characterized in that: a drive roller 5 is rotatably connected to one end of the top inner wall of the first support rod 1, a driven roller 6 is rotatably connected to the other end of the top inner wall of the first support rod 1, one end of the first rotating shaft 4 is fixed to the drive roller 5, and conveyor belts 7 are fixed to both ends of the outer walls of the drive roller 5 and the driven roller 6. A feeding mechanism is located in the middle of one side of the first support rod 1, a third support rod 8 is fixed to the middle of the other side of the first support rod 1, an electromagnet 9 is fixed to one side of the third support rod 8, and fifth support rods 15 are fixed to both sides of the first support rod 1. A material distribution mechanism is movably installed in the middle of the two fifth support rods 15.

[0036] Among them, the electromagnet 9 is located at the bottom of the conveyor belt 7. The electromagnet 9 works by having opposite magnetic properties to the ferrite magnetic sheet. The electromagnet 9 pushes the ferrite magnetic sheet upward. The position of the ferrite magnetic sheet is different depending on the magnitude of the magnetic force due to the influence of the magnetism and its own gravity.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In this invention, the ferrite magnetic sheets to be tested are first placed sequentially on top of the conveyor belt 7. The first servo motor 3 drives the first rotating shaft 4 to rotate, which in turn drives the active roller 5 to rotate and transport the magnetic sheets. Two electromagnets 9 are energized, creating a magnetic field between them. When the ferrite magnetic sheet moves to the electromagnet 9, it is subjected to the magnetic field force and moves upward. Due to the influence of magnetic force and its own gravity, the ferrite magnetic sheet is positioned at different horizontal heights. The positions of the three grading plates 17 are adjusted according to the different specifications of the ferrite magnetic sheets. The slider 18 is moved in the chute 16 to adjust the position. After adjustment... After completion, the limit bolt 19 is rotated to limit the magnetic sheet. The second servo motor 10 drives the second rotating shaft 11 to rotate, so that the agitator 12 can touch the three grading plates 17 at any height. At the same time, the length of the agitator 12 is sufficient to move the suspended magnetic sheet above the grading plate 17. The top grading plate 17 is used to remove magnetic sheets with excessive magnetic force. The baffle plate 22 collects the magnetic sheets with excessive magnetic force at the top of the second guide plate 21. Magnetic sheets with qualified magnetic force fall from the middle grading plate 17 into the first guide plate 20 and finally into the collection box 14. Magnetic sheets with poor magnetic force fall onto the bottom grading plate 17.
