Adsorption mechanism for thin materials

Abstract

The invention discloses an adsorption mechanism for thin materials, comprising a first adsorption unit and a gas circuit unit, the first adsorption unit includes a first body, and the first body is provided with a plurality of adsorption holes, and a plurality of adsorption holes are formed on the first body. The second end of each of the adsorption holes is disposed toward the thin material; the end surface of the first body facing the thin material is recessed inward to form a diversion groove, wherein at least one of the adsorption holes is correspondingly provided with the A guide groove, the first end of the guide groove extends to the outer side wall of the first body, and the second end extends to the inner side wall of the first body, so that the inside of the guide groove faces the outer wall of the first body. The flow velocity of the airflow flowing through the adsorption hole is greater than the airflow velocity of the side of the thin material that faces away from the first body. The present invention at least includes the following advantages: by adopting the arrangement of the first adsorption unit, the vacuum adsorption combined with the design of the airflow velocity on both sides of the thin material can effectively ensure the effectiveness of the adsorption mechanism on the thin material.

Description

technical field [0001] The invention relates to the technical field of handling, in particular to an adsorption mechanism for thin material parts. Background technique [0002] The descriptions in this section merely provide background information related to the present disclosure and do not constitute prior art. [0003] Test strips are one of the most common manifestations of thin materials. The production of test strips is usually an assembly line operation, and one of the necessary processes is to transfer the adsorbed test strips. The test paper includes a diversion layer, a detection layer and a water absorption layer, wherein the diversion fibers of the diversion layer have large pores, and usually due to more air leakage during the adsorption process, the adsorption force is not enough to absorb the diversion. The layer in turn causes the test strip to fall off during handling. [0004] At present, for the above-mentioned falling phenomenon, manufacturers generally...

Problems solved by technology

Wherein the test paper includes a diversion layer, a detection layer and a water-absorbing layer, wherein the diversion fiber of the diversion layer has relatively large pores, and usually due to more air leakage during the adsorption process, the adsorption force is not enough to absorb the diversion layer. layer and thus make the test paper fall during handling

[0004] At present, for the above-mentioned drop phenomenon, manufacturers generally adopt to increase the adsorption force of the suction nozzle, so that on the one hand, it cannot completely solve the drop of the test paper, and on the other hand, it is easier to cause damage to the surface of the test paper.
