Problems solved by technology

There are many ways to break the amorphous or nanocrystalline strips into granular states. For example, the patent application No. 201280062847.1 describes the magnetic field shielding sheet and its manufacturing method and the receiving device for wireless charging. The document mentions the use of mechanical pressure. The method breaks the strip, and the adhesive layer of the insulating double-sided adhesive enters between the fine fragments, making the fine fragments insulated, reducing the eddy current loss in the coil coupling state of electromagnetic induction, and improving the charging efficiency. Through a single amorphous magnetic sheet The top and bottom are protected by release film and double-sided tape to crush the flakes. However, this method requires a lot of waste of manpower and material resources, and has the disadvantages of being unable to continuously produce and the production process is cumbersome, and the product performance stability and reliability are not good. high

Embodiment 1

[0026] like Figure 1-2 In the shown continuous crushing device, a frame 1 is arranged in the continuous crushing device. The two ends of the frame 1 are respectively provided with an unwinding system 2 and a winding system 3, both of which are of conventional design and will not be repeated here. A conveying device is provided between the unwinding system 2 and the winding. In the first embodiment, the conveying device is composed of a conveying belt 4, two conveying rollers 5 and a conveying motor driving the conveying rollers 5 to rotate. The conveying roller 5 is driven by a conveying motor, and the conveying roller 5 drives the conveyor belt 4 to rotate, and the conveying belt 4 is formed with a conveying base surface 6 for placing amorphous or nanocrystalline strips.

[0027]Along the traveling direction of the strip, the conveying device is provided with a crushing area 7 and a detection area 8 . In the crushing area 7, two sets of crushing rolls 9 and two sets of re...

Embodiment 2

[0035] The difference between this embodiment 2 and embodiment 1 is that in this embodiment 2, if Figure 3-4 As shown, the unwinding system 2 is also provided with a tension control device and a deviation correction device. In the present embodiment 2, the tension control device is composed of a tension sensor 20 and a tension controller, wherein the tension sensor 20 is installed near the conveyor belt 4 and is electrically connected with the data processing module for detecting the tension on the surface of the strip; the tension control The device is electrically connected with the motor of the winding roller and is electrically connected with the data processing module, and is used for controlling the rotation speed of the motor of the winding roller and adjusting the linear speed of the winding roller. Since the strip is wound on the winding roller, the diameter of the coil on the winding roller must become larger and larger. At this time, the tension of the strip must c...

Abstract

The invention discloses a continuous crushing device for a magnetic isolating plate. The continuous crushing device comprises an unwinding system and a winding system; particularly, a conveyer is arranged between the unwinding system and the winding system; a conveying base surface for placing a strip is formed on the conveyer; a crushing region and a detecting region are arranged on the conveyer along the advancing direction of the strip; multiple groups of crushing roller sets for crushing the strip and multiple groups of resetting roller sets for shaping the strip are arranged in the crushing region; the crushing roller sets and the resetting roller sets are adjacently arranged; the crushing roller sets are located at the upper parts of the resetting roller sets; and a detection device for detecting the performance of the strip is arranged in the detection region. According to the continuous crushing device for the magnetic isolating plate, the defects that an existing product cannot be continuously produced and the production process is complicated are overcome; the processing cost is reduced; the stability of the product performance is improved by full-automatic production; and the strip can be continuously and quickly crushed.

Description

technical field [0001] The invention relates to a crusher, in particular to a continuous crushing device for a magnetic isolation sheet. Background technique [0002] Since the gradual popularization of portable electronic products such as mobile phones and notebook computers, the "light and thin" design concept has been leading the development direction of the market. Major manufacturers are also constantly strengthening technology research and development, trying to make portable electronic products thinner. If the wireless charging module wants to be implanted into portable electronic products as a built-in device, the magnetic isolation sheet that plays a key role must be "light and thin". [0003] Amorphous strip is a solid thin strip formed by ultra-rapid solidification with a thickness in the range of 15 μm to 35 μm. When the alloy is solidified, the atoms have no time to arrange and crystallize in an orderly manner, and the solid alloy is obtained. This solid alloy ...
