Particle capturing seal

Abstract

The utility model relates to a particle trapping seal which comprises a particle trapping head, a connecting column, a handle and dust falling adhesive paper. The whole particle trapping head is in a cuboid shape, the upper face of the particle trapping head is vertically connected with the connecting column, and the other end of the connecting column is connected with the handle. An arc-shaped face is arranged on the side, away from the connecting column, of the particle capturing head, and dust falling adhesive paper is detachably connected to the arc-shaped face. The device has the advantages that when the device is used, particles can be collected only by placing the particle trapping head on the surface of a product to be subjected to dust collection and then moving back and forth and rolling, and after collection is completed, dust sticking paper is torn off from an arc-shaped surface, moved into a slide and placed into a scanning electron microscope sample bin for particle element material analysis; and due to the design of the arc-shaped surface on the particle trapping head, the dust falling adhesive paper on the arc-shaped surface can ensure consistent adhesive force in the collection process, so that the surface material of the product is prevented from being peeled off as much as possible, and the accuracy of product cleanliness analysis is effectively improved.

Description

Technical Field

[0001] The utility model relates to the technical field of particle capture tools, and more specifically, to a particle capture seal. Background Art

[0002] In the fields of automobile manufacturing, aviation, precision machinery, semiconductor manufacturing, food processing, health care or medicine, etc., the demand for understanding the technical cleanliness of components, devices, products, workpieces or contact surfaces whose surfaces are susceptible to dust is increasing day by day. For example, in the field of automobile driving, there is an increasing need to clearly understand the particle contamination degree of fuel injection systems, brake systems, liquid systems or miniaturized and performance-enhanced independent components, as well as complex components manufactured on this basis.

[0003] Generally, due to the overly large surface area of the test sample, or due to complex shapes and uneven surfaces, it is impossible to observe and test using the direct method. At this time, the commonly used method is to remove the dust on the surface through a sticky film or cleaning liquid, and perform test analysis on the cleaning liquid, filter residue or sticky film according to particle size, distribution and chemical properties. The above method can reduce the probability of secondary pollution during the test process. In order to reduce the test time, improve the reproducibility of measurement results and reduce the probability of artificial pollution, the entire observation and test process is preferably automated.

[0004] Traditionally, surface particles are collected through a sticky film. The collected product uses the sticky paper on the surface. When collecting particles, it mostly uses planar pasting and then peeling or manual pasting and then peeling. The force is not uniform and the adhesion is inconsistent, resulting in peeling and collecting the product's own material together when collecting surface particles of the product, resulting in a large error in the analysis of the product cleanliness. Using arc surface contact can significantly balance the pasting force and reduce the strength during peeling.

[0005] The foregoing description is to provide general background information and does not necessarily constitute prior art. Summary of the Utility Model

[0008] Furthermore, the dust-removing adhesive paper comprises a collecting sticker body and a transparent adhesive layer, the collecting sticker body is in the shape of a square sheet, and the transparent adhesive layer is provided on the upper and lower sides of the collecting sticker body; wherein the transparent adhesive layer and the arc-shaped surface are detachably bonded.

[0009] Furthermore, the connection column and the particle collecting head and the handle are smoothly connected.

[0010] Furthermore, the handle includes a connecting handle and an end handle; the connecting handle is in the shape of a bottleneck with thick ends and a thin middle, and the connecting column is smoothly connected to the middle of the connecting handle; the end handles are smoothly connected to both ends of the connecting handle, and the end handles are in the shape of a cone.
