[0025] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0026] The utility model provides a kind of silver glue coating needle's automatic cleaning mechanism to solve the drip liquid phenomenon of silver glue that coating needle in prior art is generated when not working, to cause the problem of cross contamination and product electrical performance bad.

[0027] For the convenience of understanding, the specific process in the embodiments of the present application will be described below, please refer to Figs. 1 to 3 The automatic cleaning mechanism of silver glue coating needle in the embodiments of the present application includes bottom plate 1, stand 2, coating needle 3, accommodation part 4, adsorption component 5 and support frame 6;The stand 2 is vertically arranged on the bottom plate 1;The coating needle 3 can be transversely moved and arranged on the stand 2 to be raised and lowered;The accommodation part 4 is rotatably arranged on the support frame 6, the support frame 6 is arranged on the bottom plate 1 and located below the coating needle 3;The adsorption component 5 is arranged in the accommodation part 4, and the adsorption component 5 is full of alcohol.

[0028] The automatic cleaning mechanism of silver glue coating needle of the utility model, when the coating needle 3 is in standby state, coating needle 3 is automatically transversely moved above the accommodation part 4, and then the coating needle is moved downward to insert into the adsorption component 5 full of alcohol.

[0029] In an embodiment, referring to Fig. 1 The coating needle 3 can be transversely moved above the accommodation part 4 by transverse module 20, and the coating needle 3 can also be moved up and down above the accommodation part 4, which can be automatically lowered by vertical slide rail or manually operated.

[0030] In an embodiment, the accommodating part 4 comprises an accommodating frame 42, which is disc-shaped, and is rotatably arranged on the support frame 6 by a rotating motor 41, which is installed on the support frame 6; a cylinder 43 for placing the adsorbing part 5 is arranged at the center of the accommodating frame 42; a rotatable shielding plate 44 is arranged above the cylinder 43; and a circular hole 45 for the coating needle to pass through is arranged on the shielding plate.

[0031] Specifically, referring to Fig. 2 , the cylinder 43 is used to adapt to the subsequent adsorbing part 5, and the shielding plate 44 is used to shield the upper end of the adsorbing part 5 in the cylinder; since the adsorbing part 5 is filled with alcohol, covering it by the shielding plate 44 can reduce the evaporation rate of the alcohol, so that the adsorbing part 5 can be used for a longer time.

[0032] In an embodiment, referring to Fig. 3 , a plurality of accommodating holes 50 for adapting to the coating needle are arranged in the adsorbing part 5; when the adsorbing part 5 rotates with the accommodating frame 42, the accommodating holes 50 also rotate, so that the accommodating holes which are not inserted by the coating needle can correspond to the circular hole 45, the coating needle can be easily inserted into the corresponding accommodating hole, the silver glue on the coating needle can fall into the accommodating hole, and the coating needle can be cleaned by the alcohol.

[0033] In an embodiment, the adsorbing part 5 is a sponge, and can also be made of other materials, which can adsorb alcohol and allow the coating needle to be easily inserted.

[0034] In an embodiment, the plurality of accommodating holes 50 are distributed in a circular array along the edge of the adsorbing part 5 and centered on the center of the adsorbing part 5, so that when the adsorbing part 5 rotates, each accommodating hole 50 can correspond to the coating needle 3 in turn, and the coating needle 3 can be easily inserted.

[0035] When in operation, the coating needle can be adapted to the related process; when the production is in a stop state, the coating needle 3 is horizontally moved to above the adsorbing part 5 by a horizontal module, the coating needle automatically descends, passes through the circular hole 45, and is inserted into the accommodating hole 50 of the adsorbing part 5, so that the coating needle 3 is located in the sponge filled with alcohol, the silver glue automatically falls into the sponge, and the coating needle can be cleaned.

[0036] When the needle coating needs to work, the coating needle automatically rises and leaves the adsorbing part, the rotating motor drives the adsorbing part to automatically rotate, so that the position of the accommodating hole in the contaminated sponge moves away, and thus the position of the uncontaminated sponge can be aligned with the coating needle to be cleaned.

[0037] In conclusion, through the automatic cleaning mechanism, the adsorption component is kept unobstructed in the sealed alcohol solution, and the replacement frequency of the adsorption component is 1 time per 12 hours, which greatly improves the service life.

[0038] The automatic cleaning mechanism of the silver glue coated needle head adopts a special small tank, ensures that the silver glue residue is collected in the special box, and eliminates the pollution source; the sealing cover effectively protects the alcohol from being volatilized, keeps the inside of the sponge moist, and keeps the needle head unobstructed for a long time.

[0039] The above-described and above-mentioned examples are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
