Description

Vacuum adsorption jig

Technical Field

The utility model relates to an electronic product check out test set technical field specifically is a vacuum adsorption tool.

Background

With the rapid development of light, thin and small electronic products, flexible screens are widely popularized. When detecting the flexible screen, adopt sucking disc formula structure to adsorb the flexible screen usually, the sucking disc links to each other with air exhaust device, and air exhaust device during operation can make the adsorption plane department of sucking disc form the negative pressure, and then realizes the adsorption effect to the flexible screen, and the sucking disc formula structure adsorbs behind the flexible screen shifts it to detection mechanism's top and detects. However, sucking disc formula structure among the prior art includes a plurality of suction nozzles usually, and a plurality of suction nozzles adsorb the flexible screen simultaneously, and a plurality of suction nozzles can only adsorb the intermediate position of flexible screen usually, because the characteristic of flexible screen, the marginal position that does not contact with the suction nozzle on the surface of flexible screen can be with the adsorbed surface of flexible screen and be double-layered angular distribution under the effect of gravity, and the front end that causes the flexible screen has the image to counterpoint the error with counterpoint camera to influence the testing result.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vacuum adsorption tool to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a vacuum adsorption tool, includes the last absorption piece and the lower absorption piece that can dismantle the connection, go up and adsorb and seted up multiunit absorption hole on the piece, the absorption hole runs through and adsorbs the piece, the air flue has been seted up on the top surface that adsorbs piece and last absorption piece contact down, air flue one end intercommunication and the corresponding air duct of absorption hole, the inlet port that its other end intercommunication and air inlet assembly are connected.

Preferably, the diameter of the adsorption hole is 1 mm.

Preferably, the upper adsorption block and the lower adsorption block are both made of aluminum.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up detachable and adsorb piece and lower adsorption piece on, and be provided with multiunit adsorption hole on the last adsorption piece, be provided with on the lower adsorption piece with adsorption hole matched with air flue, air pocket and inlet port, under the effect of negative pressure subassembly, the adsorption hole can be effectual adsorbs the product subassembly, compared with the cross sectional area of the suction nozzle among the prior art, the cross sectional area of adsorption hole is less, it adsorbs the flexible screen to adopt the mode of point adsorption to be similar to, therefore, the border position of flexible screen also can correspond and set up more absorption holes of quantity, realize the level and smooth absorption of flexible screen front end, prevent that the front end of flexible screen from appearing the phenomenon of droing, reduce the image counterpoint error of flexible screen and counterpoint camera, make the testing result more accurate; meanwhile, the upper adsorption block and the lower adsorption block made of aluminum materials are convenient to process, the processed flatness is high, and the air tightness of the whole assembly is improved.
