Description

Technical Field

[0001] The utility model relates to the technical field of shielding piece detection, in particular to a shielding piece flatness detection tool. Background Art

[0002] With the rapid development of science and technology, the field of wireless charging products is moving towards high charging efficiency, small eddy current loss, low heat generation during charging, and increased charging induction distance. However, many technical difficulties have also been encountered during the development process, such as low charging efficiency, high cost, and too short effective charging distance.

[0003] In order to obtain higher charging efficiency and reduce or eliminate the impact of electromagnetic fields on electronic products during charging, electromagnetic shielding sheets are needed for shielding. The function of electromagnetic shielding sheets is to isolate electromagnetic waves and prevent metals and other materials from absorbing electromagnetic waves emitted by the transmitting device and generating magnetic fields in the opposite direction. In the wireless charging receiving end, if there is no electromagnetic shielding sheet, it will be difficult for the wireless charging device to complete the close-range charging work.

[0004] As a type of shape and position error, flatness has a very important impact on the quality of electromagnetic shielding sheets. When used, electromagnetic shielding sheets are often first sucked by a robot before being put into the subsequent assembly process, and the flatness of the electromagnetic shielding sheet will directly affect the suction efficiency of the robot.

[0005] In the prior art, flatness detection is usually performed through manual observation with the naked eye, which requires extremely high processing experience, and human judgment is prone to large errors, affecting subsequent processing quality and efficiency. Utility Model Content

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.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0029] A shielding sheet flatness detection tool, comprising:

[0030] Bottom plate 1;

[0031] The movable plate 2 is connected to the bottom plate 1 in a flippable manner, and an adjustable angle is provided between the movable plate 2 and the bottom plate 1;

[0032] Two gaskets 4 are arranged at a certain distance on a side of the movable plate 2 away from the bottom plate 1;

[0033] The cover plate 3 is arranged on two gaskets 4 , and a through slot 5 for the shielding sheet to pass through is formed between the adjacent surfaces of the movable plate 2 and the cover plate 3 and between the two gaskets 4 .

[0034] Specifically, the utility model provides a detection tool for the flatness of a shielding sheet to solve the problems existing in the prior art. The detection tool comprises a base plate 1, a movable plate 2, a cover plate 3 and two gaskets 4, wherein the movable plate 2 is rotatably arranged above the base plate 1, the cover plate 3 is arranged on the side of the movable plate 2 away from the base plate 1, the two gaskets 4 are arranged between the movable plate 2 and the cover plate 3 at a certain distance, the movable plate 2, the cover plate 3 and the two gaskets 4 communicate with a through slot 5 for the shielding sheet to pass through, the movable plate 2 is arranged on the base plate 1 at a certain angle, if the shielding sheet to be tested is a good product, it will slide down smoothly through the through slot 5, if the shielding sheet to be tested is a defective product, it cannot pass through the through slot 5 due to its poor surface flatness, thereby testing the shielding sheet.

[0035] In a preferred embodiment, a lifting rod 6 is provided on the side of the bottom plate 1 close to the movable plate 2, and the upper end of the lifting rod 6 abuts against the side of the movable plate 2 close to the bottom plate 1 to support the movable plate 2, and the angle between the movable plate 2 and the bottom plate 1 is adjusted based on the lifting of the lifting rod 6.

[0036] Specifically, the lifting rod 6 is vertically arranged on the bottom plate 1 and supported below the movable plate 2. The tilt angle of the movable plate 2 is changed according to the up and down movement of the lifting rod 6 to ensure that the shielding sheet can slide down along the surface of the movable plate 2 at a stable speed.

[0037] In a preferred embodiment, one end of the movable plate 2 is rotatably connected to the base plate 1 via a flip assembly 7 .

[0038] Specifically, the adjustability of the tilt angle between the bottom plate 1 and the movable plate 2 is achieved by setting the lifting rod 6 and the flip assembly 7 .

[0039] In a preferred embodiment, the flip assembly 7 is a hinge.

[0040] In a preferred embodiment, the distance between the two gaskets 4 is not less than the length of the shielding sheet.

[0041] Specifically, the shielding sheet is more likely to have poor flatness in the length direction, and the spacing of the gaskets 4 needs to ensure that the long side of the shielding sheet can smoothly pass through the through slot 5.

[0044] Specifically, the inclination angle between the plate and the movable plate 2 is preferably 30° to 60°. If the inclination angle is too small, the shielding sheet will slide down too slowly, which will affect the detection efficiency; if the inclination angle is too large, the shielding sheet will not be completely fitted to the surface of the movable plate 2, and there will be a phenomenon that it cannot accurately enter the through slot 5. In addition, some defective products may still pass through the through slot 5 due to inertia, thereby affecting the accuracy of detection.

[0045] In a preferred embodiment, the thickness of the two gaskets 4 is consistent with the thickness of the shielding sheet.

[0046] In a preferred embodiment, two gaskets 4 are detachably arranged on a side of the movable plate 2 away from the bottom plate 1 .

[0048] In a preferred embodiment, the corresponding surfaces of the movable plate 2 and the cover plate 3 are both flat surfaces.

[0049] Specifically, the surfaces corresponding to the movable plate 2 and the cover plate 3 are both planes, so as to avoid the influence of other factors on the detection.
