Description

Technical Field

[0001] The utility model relates to the technical field of removing metal impurities from material strips, in particular to an impurity removing device. Background Art

[0002] In order to meet the requirements of mobile phone wireless charging efficiency, soft magnetic materials are becoming more and more popular in the 3C consumer electronics industry. In the unbroken state, the magnetic permeability of soft magnetic materials can reach 13000H / m. In order to reduce the heat generated by mobile phone wireless charging, it is necessary to use professional tools to crush the surface of soft magnetic materials. Under the pressure of professional tools, the originally smooth and flat surface of soft magnetic materials will present several fine grid shapes, so as to meet the product performance requirements. In order to prevent the product surface from being damaged by professional tools, a release film tape is used as a protective material. During the processing, soft magnetic materials will produce a large amount of metal debris attached to the release film tape. When the release film tape is recycled, the debris attached to the release film tape will be embedded in the release film tape, causing the grid to deform or the grid to short-circuit, resulting in a reduction in the charging efficiency of mobile phones using the soft magnetic material. In the related art, after the release film tape is recycled, the operator is required to manually remove the metal impurities in the tape later, thereby delaying the operator's work efficiency.

[0034] refer to Figure 2 The utility model provides an impurity removal device. According to an embodiment of the utility model, the impurity removal device includes a magnetic attraction portion 100 and a driving component 200 .

[0035] There are at least two magnetic attraction parts 100, and the two magnetic attraction parts 100 are arranged in parallel and opposite to each other on both sides of the material strip; a gap is formed between the two magnetic attraction parts 100 for the material strip to pass through; the two ends of the driving component 200 are connected to the magnetic attraction parts 100, and the two ends of the driving component 200 can approach or move away from each other to drive the magnetic attraction parts 100 to approach or move away from the material strip.

[0036] It should be noted that, in the present embodiment, there are two magnetic suction parts 100, the material strip has two sides, and a gap is formed between the two magnetic suction parts 100 for the material strip to pass through. The magnetic suction part 100 uses magnetic force to adsorb the residual metal impurities on both sides of the material strip to the magnetic suction part. In order to ensure a good adsorption effect on the metal debris remaining on both sides of the material strip, thereby removing the residual metal impurities in the material strip, the adsorption surface of the magnetic suction part 100 is always kept parallel to the material strip. When the driving component 200 adjusts the distance between the magnetic suction part 100 and the material strip, it is helpful to avoid direct contact between the magnetic suction part 100 and the material strip, thereby avoiding scratching the material strip by the magnetic suction part 100. In addition, the driving component 200 drives the magnetic suction part 100 to approach or move away from the material strip, and can flexibly adjust the distance between the magnetic suction part 100 and the material strip according to actual conditions, thereby adjusting the adsorption force of the magnetic suction part 100 on the metal debris remaining on both sides of the material strip, thereby ensuring the adsorption effect.

[0037] refer to Figures 1 to 3 According to the impurity removal device of the embodiment of the utility model, the driving component 200 includes a cylinder 210, and the cylinder 210 includes a main body 211 and a piston rod 212. The main body 211 drives and connects the piston rod 212. There are at least two piston rods 212, and the two piston rods 212 can extend or retract into the main body 211. Each piston rod 212 is connected to a magnetic attraction part 100.

[0038] It should be understood that the cylinder 210 has a simple structure, stable movement, small size and light weight. Using the cylinder 210 to adjust the distance between the magnetic attraction part 100 and the material strip can make the entire device lighter and convenient to fine-tune the position of the cylinder 210, so that the magnetic attraction part 100 has good adsorption force on the metal debris remaining on both sides of the material strip, thereby optimizing the removal effect of metal impurities. In addition, compared with hydraulic transmission, the working medium of the cylinder 210 is clean, which prevents the material in the cylinder 210 from contaminating the material strip.

[0039] It should be noted that, in order to ensure the magnetic attraction part 100 has an adsorption effect on the metal debris remaining on both sides of the material strip, there are at least two piston rods 212, and the two piston rods 212 can extend or retract into the body 211, and each piston rod 212 is connected to a magnetic attraction part 100. Optionally, the magnetic force of the magnetic attraction part 100 is the same, and the two piston rods 212 can extend or retract into the body 211 at the same speed and stroke, so that the distance between each magnetic attraction part 100 and the material strip is equal, thereby maintaining the same adsorption force of the magnetic attraction part 100 on the metal debris remaining on both sides of the material strip, so that the metal debris on both sides of the material strip can be quickly adsorbed to the magnetic attraction part 100, avoiding the phenomenon that the metal debris on one side of the material strip is not adsorbed cleanly.

[0040] As another embodiment of the present invention, a bidirectional screw mechanism may be used instead of the cylinder 210 to enable the magnetic attraction portion 100 to approach or move away from the material belt at a constant speed and a constant distance.

[0041] refer to Figure 1 and Figure 5 According to the impurity removal device of the embodiment of the utility model, it also includes a control component 300 , which is electrically connected to the body 211 , and the control component 300 can control the piston rod 212 to extend or retract into the body 211 .

[0042] It should be noted that during use, the magnetic attraction part 100 needs to be appropriately close to the material strip so that the adsorption force of the magnetic attraction part 100 can adsorb the metal debris remaining on both sides of the material strip to the magnetic attraction part 100. When too much metal debris accumulates on the magnetic attraction part 100, it is necessary to clean these metal debris. At this time, the control component 300 controls the piston rod 212 to extend out of the main body 211, so that the magnetic attraction part 100 maintains a long distance from the material strip, and the metal debris on the magnetic attraction part 100 can be cleaned without moving the device and the material strip.

[0043] According to the impurity removal device of the embodiment of the present invention, the magnetic attraction portion 100 includes a magnet 120 and a housing 110 . The magnet 120 is disposed in the housing 110 , and the housing 110 is connected to the driving assembly 200 .

[0044] It should be noted that when the magnet 120 is exposed to the air, the oxygen and moisture on the surface of the magnet 120 will begin to react with the magnet 120, thereby generating rust, which in turn affects the magnetism of the magnet 120, resulting in poor magnet 120 adsorption of metal debris remaining on both sides of the material strip, so the magnet 120 is set in the shell 110, and the magnet 120 is protected by the shell 110 to extend the service life of the magnet 120. In addition, the metal debris remaining on both sides of the material strip will not be directly adsorbed onto the magnet 120, but will be adsorbed onto the shell 110, so that the staff will not cause damage to the magnet 120 when cleaning the metal debris.

[0045] Optionally, the magnet 120 can be an electromagnet 120. When metal debris on the shell 110 needs to be cleaned, the electromagnet 120 is demagnetized to facilitate the staff to clean the metal debris on the shell 110. When the metal debris remaining on both sides of the material belt needs to be adsorbed, the electromagnet 120 maintains its magnetism.

[0046] According to the impurity removal device of the embodiment of the present invention, the magnets 120 in the plurality of magnetic attraction parts 100 are arranged opposite to each other with the same magnetic poles.

[0047] It should be noted that when two magnets 120 are close to each other, their magnetic field lines will overlap, which means that their energy density will increase. The energy density between two magnets 120 with the same poles facing each other will be higher because their magnetic field lines are in the same direction. In this way, it can be ensured that the magnet 120 has sufficient adsorption force, so that the magnet 120 can adsorb metal debris on the fabric strip opposite to its own adsorption surface.

[0048] refer to Figure 4 According to the impurity removal device of the embodiment of the utility model, an adsorption groove 111 is provided on a side of the shell 110 close to the material belt, and the adsorption groove 111 penetrates the shell 110 .

[0049] It should be noted that the adsorption groove 111 penetrates the outer shell 110 in the horizontal direction, and the metal debris adsorbed on the outer shell 110 will gather in the adsorption groove 111. When cleaning the metal debris, the metal debris can be scraped out along the length direction of the adsorption groove 111, thereby achieving the effect of facilitating the cleaning of the metal debris on the outer shell 110.

[0050] refer to Figure 1 According to the impurity removal device of the embodiment of the utility model, the adsorption groove 111 includes a first inclined surface 112, a second inclined surface 114 and a bottom surface 113, one end of the bottom surface 113 is connected to the first inclined surface 112, and the other end is connected to the second inclined surface 114, and the first inclined surface 112 and the second inclined surface 114 are both inclined toward the bottom surface 113.

[0051] It should be noted that when the staff cleans the metal debris in the adsorption groove 111, the metal debris on the first inclined surface 112 and the second inclined surface 114 can be scraped onto the bottom surface 113, and then the concentrated metal debris can be scraped out of the adsorption groove 111, thereby increasing the convenience of cleaning the metal debris on the outer shell 110.

[0052] refer to Figure 5 According to the impurity removal device of the embodiment of the utility model, the control component 300 includes a manual switch 320 and a solenoid valve 310 , the manual switch 320 is arranged on the solenoid valve 310 , and the manual switch 320 is connected to the valve core of the solenoid valve 310 .

[0053] It should be understood that when the staff needs to adjust the distance between the magnetic attraction part 100 and the material belt, they only need to adjust the manual switch 320 to control the piston rod 212 to extend or retract into the body 211, and the stroke can be flexibly adjusted. The solenoid valve 310 has a simple structure and a low price. It is easier to install and maintain than other types of actuators such as regulating valves. This is conducive to cost savings when the impurity removal device is put into mass production.

[0054] refer to Figure 1 and Figure 5 According to the impurity removal device of the embodiment of the utility model, the control component 300 also includes a mounting plate 330, the mounting plate 330 connects the body 211 and the solenoid valve 310, and the mounting plate 330 is arranged along the height direction.

[0055] It should be understood that in actual production activities, a reel is needed to collect and transport the material tape, and the most convenient way to install the reel is to install it in the horizontal direction or in the height direction. The two magnetic suction parts 100 need to be arranged in parallel and opposite to each other on both sides of the material tape to ensure a good adsorption effect on the metal debris remaining on both sides of the material tape. Therefore, the mounting plate 330 is arranged in the height direction so that the body 211 is fixed in a vertical or horizontal state, so that the telescopic direction of the piston rod 212 is adapted to the installation state of the reel, and the magnetic suction parts 100 are arranged in parallel on both sides of the material tape.

[0056] The mounting plate 330 is provided with a connecting hole 331 , which is arranged along a height direction or a horizontal direction. The connecting hole 331 is used to pass through a connecting member and slide with the connecting member so that the body 211 is fixed in a vertical or horizontal state.

[0057] It should be understood that the mounting plate 330 is provided with a connecting hole 331 , which is arranged along a height direction or a horizontal direction, and is used to pass through a connecting member and to slide with the connecting member.

[0058] It should be noted that if the winding drum is installed and fixed in the height direction, the mounting plate 330 is fixed in a horizontal state through the connecting piece and the connecting hole 331, so that the magnetic attraction part 100 is arranged in parallel on both sides of the material strip; if the winding drum is installed and fixed in the horizontal direction, the mounting plate 330 is fixed in a vertical state through the connecting piece and the connecting hole 331, so that the magnetic attraction part 100 is arranged in parallel on both sides of the material strip.

[0059] In addition, when the winding drum cannot move, the connecting hole 331 is used to pass through the connecting piece and slide with the connecting piece. The installation position of the entire device can be fine-tuned by sliding the connecting piece and the connecting hole 331, so that the magnetic attraction part 100 is at an appropriate distance from the material strip.

[0060] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
