Description

Technical Field

[0001] The utility model relates to the technical field of magnetic isolation sheet production, in particular to a magnetic isolation sheet rolling device for wireless charging. Background Art

[0002] A wireless charging magnetic shield is a component used in wireless charging devices. Its main function is to help wireless charging devices achieve electromagnetic induction wireless charging. Wireless charging magnetic shields are usually made of ferrite or other magnetic materials, and have high magnetic permeability and magnetic induction intensity. They are placed between the transmitter and receiver of the wireless charging device to form a magnetic circuit. When the transmitter is working, it will generate an alternating magnetic field. This magnetic field passes through the magnetic shield to form a loop. The receiver generates an induced current in the magnetic field of the magnetic shield, thereby achieving wireless charging. In order to prevent the magnetic shield from interrupting during the application process, the magnetic shield needs to have a certain flexibility. Therefore, in order to meet this requirement, the magnetic shield needs to be evenly rolled, and a rolling device is required to roll it.

[0004] The device screens the magnetic isolation sheets placed on the conveyor belt by setting up a height-adjustable shielding mechanism to ensure that multiple layers of magnetic isolation sheets will not overlap and be crushed during rolling. However, the device does not limit the position of the magnetic isolation sheets when they are transported by the conveying device. When the magnetic isolation sheets move, they are very likely to shift in position at the upper end of the conveying device, resulting in the inability to completely crush them during rolling.

[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original structure of the magnetic isolation sheet rolling device for wireless charging. Utility Model Content

[0011] Preferably, a top plate is screwed onto the upper end of the first support plate, and a baffle is fixedly mounted onto the lower end of the top plate, and the baffle is correspondingly distributed up and down with the upper surface of the conveying device; this structure can screen the stacked magnetic isolation sheets through the setting of the baffle.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides the following technical solutions:

[0029] Embodiment 1: Figure 1-Figure 3 The technical solution shown: a magnetic isolation sheet rolling device for wireless charging, discloses: a base 1, a support leg 2 is fixedly installed at the lower end of which, and the support leg 2 provides support for the base 1; also includes: a conveying device 3 is installed at the upper end of the base 1, and first support plates 4 are symmetrically arranged at both ends of the conveying device 3, and the first support plate 4 is fixedly installed on the upper surface of the base 1, and a limiting component is installed on the inner side of the first support plate 4, and the magnetic isolation sheet is prevented from positional displacement by the limiting component;

[0030] The limiting assembly includes a telescopic spring 5 and a limiting clamping plate 6. The telescopic spring 5 is fixedly installed on the inner side of the first support plate 4, and the tail end of the telescopic spring 5 is fixedly connected to the limiting clamping plate 6. The bottom of the limiting clamping plate 6 is flush with the upper surface of the conveying device 3, and two groups of limiting clamping plates 6 are symmetrically arranged at both ends of the conveying device 3. A sliding rod 7 is fixedly installed on the outer side of the limiting clamping plate 6, and the sliding rod 7 passes through the inner side of the first support plate 4; a threaded groove 8 is opened on the inner side of the first support plate 4, and a fastening bolt 9 is threadedly connected to the inner side of the threaded groove 8, and the tail end of the fastening bolt 9 is distributed in left-right correspondence with the limiting clamping plate 6; a top plate 10 is screwed on the upper end of the first support plate 4, and a baffle 11 is fixedly installed on the lower end of the top plate 10, and the baffle 11 is distributed in upper and lower correspondence with the upper surface of the conveying device 3;

[0031] When the magnetic isolation sheet needs to be rolled, this structure first places the magnetic isolation sheet on the upper end of the conveying device 3, and conveys the magnetic isolation sheet through the conveying device 3. During the conveying process, the fastening bolts 9 on the inner side of the threaded groove 8 are rotated to push out the limit clamps 6 at both ends of the conveying device 3 (the telescopic spring 5 is stretched), and the magnetic isolation sheet is moved to a suitable position of the conveying device 3 by the limit clamps 6. The moving trajectory of the magnetic isolation sheet is limited to prevent it from being offset when being transported at the upper end of the conveying device 3 and being misaligned with the rolling device at the rear end. When the size of the magnetic isolation sheet is too large, the fastening bolts 9 are rotated in the opposite direction, so that the limit clamps 6 lose the limit passage of the fastening bolts 9. The elastic force of the telescopic spring 5 is used for resetting, so that the limit clamp 6 can achieve the effect of automatic resetting. Through the above structure, magnetic isolation sheets of different sizes can be limited to prevent them from positional displacement when moving at the upper end of the conveying device 3, and a baffle 11 is installed at the lower end of the top plate 10. The distance between the baffle 11 and the conveying device 3 is the thickness of the magnetic isolation sheet workpiece. When the magnetic isolation sheets are transported, if the magnetic isolation sheets are stacked, the magnetic isolation sheets stacked at the upper end will be blocked by the baffle 11 at the bottom of the top plate 10, so that the magnetic isolation sheets stacked at the upper end will slide to the rear side. Through the above structure, the screening effect is achieved, and the stacking of magnetic isolation sheets can be avoided to affect the crushing effect of the magnetic isolation sheets.

[0032] Embodiment 2 is different from Embodiment 1 in that a rolling structure is added on the basis of limiting the position of the magnetic isolation sheet, such as Figure 1-Figure 4The figure discloses: the second support plates 12 are symmetrically arranged at both ends of the conveying device 3, and the second support plates 12 are fixedly installed on the upper surface of the base 1, and the second support plates 12 and the first support plates 4 are distributed in front and back correspondence, and a rolling assembly is installed on the inner side of the second support plate 12, and the magnetic isolation sheet is rolled by the rolling assembly; the rolling assembly includes a servo motor 13 and a rolling roller 14, the servo motor 13 is fixedly installed on the outer side of the second support plate 12, and the output end of the servo motor 13 passes through the inner side of the second support plate 12, and the output end of the servo motor 13 is fixedly installed with a rolling roller 14, and the rolling roller 14 and the conveying device 3 are distributed in upper and lower correspondence;

[0033] In this structure, when the magnetic isolation sheet is conveyed to the bottom of the rolling roller 14, the servo motor 13 is operated, and the output end of the servo motor 13 drives the rolling roller 14 to rotate. The rotation of the rolling roller 14 will roll the magnetic isolation sheet at the upper end of the conveying device 3.

[0034] Embodiment 3 is different from Embodiment 2 in that a dust removal structure is added on the basis of rolling the magnetic isolation sheet, thereby improving the rolling quality of the magnetic isolation sheet by processing the dust on the outer side of the magnetic isolation sheet. Figure 1-Figure 6 The figure discloses that: a first transmission shaft 15 is fixedly installed at the output end of the servo motor 13, and the first transmission shaft 15 is connected to a second transmission shaft 17 through a transmission belt 16, a concentric shaft 18 is fixedly installed inside the second transmission shaft 17, and the concentric shaft 18 passes through the inside of the second support plate 12, and a fan blade 19 is fixedly installed at the end of the concentric shaft 18;

[0035] In this structure, when the output end of the servo motor 13 rotates, it will also drive the first transmission shaft 15 to rotate. The first transmission shaft 15 will drive the second transmission shaft 17 to rotate through the connection of the transmission belt 16. The rotation of the second transmission shaft 17 will drive the inner concentric shaft 18 to rotate together. The rotation of the concentric shaft 18 will drive the fan blades 19 fixed on the outside to rotate, thereby generating wind force through the rotation of the fan blades 19. The generated wind force will act on the upper surface of the magnetic isolation plate, so that the dust on the upper surface of the magnetic isolation plate is processed to prevent the dust from affecting the quality of the magnetic isolation plate during rolling.
