Description

Technical Field

[0001] The invention relates to the field of glue dispensing equipment, and in particular to an air blowing glue removal mechanism. Background Art

[0002] Gluing is a process, also known as gluing, coating, filling, dripping, etc. It is to apply, fill, and drip electronic glue, oil, or other liquids onto the product to make the product stick, fill, insulate, fix, and smooth the surface. In the production process, after multiple dispensing, residual glue will gradually adhere to the dispensing head. At this time, the residual glue needs to be removed before better dispensing can be performed.

[0003] After searching, the Chinese patent publication number CN108580185A discloses a residual glue cleaning mechanism for a dispensing needle, including: a blowing seat arranged on a support frame, on which a receiving cavity is formed; a plurality of micro joints arranged on the side wall of the blowing seat and connected with the receiving cavity; a guide cover plate, which is fastened to the top opening end of the receiving cavity of the blowing seat; and a dispensing cylinder unit, which is located above the guide cover plate; wherein the dispensing cylinder unit includes a base, a dispensing cylinder, and a needle, a boss is formed on the bottom end surface of the guide cover plate, a hollow cavity is also formed on the guide cover plate, and a plurality of guide grooves are formed on the side wall of the boss so that the high-pressure airflow in the receiving cavity is rotated and sprayed to the needle tip at the bottom of the needle. The residual glue cleaning mechanism for the dispensing needle can effectively remove the residual glue remaining on the needle, effectively improve the dispensing quality, and extend the service life of the needle.

[0030] A spacer layer 9 is formed between the outer wall of the receiving cup 4 and the inner wall of the outer shell 1. A plurality of external air holes 10 are provided on the side wall of the outer shell 1 and are connected to the spacer layer 9 in the accommodating chamber 3. A plurality of internal air holes 11 are provided on the side wall of the receiving cup 4. The internal air holes 11 are spaced apart in the circumferential direction and the axial direction and connect the inside of the receiving cup 4 with the spacer layer 9. The pressure generated by the high-pressure gas can be released in time to avoid the residual glue at the lower end of the dispensing head being blown back into the dispensing glue channel due to the instantaneous excessive pressure in the receiving cup, thereby affecting the subsequent dispensing effect.

[0031] The number of the inner air outlet holes 11 is greater than the number of the outer air outlet holes 10 .

[0032] At least one side wall of the outer shell 1 is a transparent side wall; The amount of glue removed in the receiving cup can be observed through the transparent side wall of the outer shell. When a certain amount is accumulated, the clamping assembly is released, and the cover plate and the outer shell are separated, so that the receiving cup can be taken out of the outer shell, which is convenient for cleaning the residual glue in the receiving cup.

[0039] The lower surface of the receiving cup 4 is in contact with the upper surface of the bottom plate of the outer shell 1 .

[0040] The working principle is: When in use, the cover plate and the outer shell are fixedly installed through the snap-fit ​​assembly, the glue dispensing head that needs to be de-glueed is inserted into the through hole from the conical groove on the cover plate, and the first air inlet hole, the second air inlet hole, the third air inlet hole and the fourth air inlet hole are supplied with air through the adapter, and then the gas is blown out from the corresponding first air outlet hole, the second air outlet hole, the third air outlet hole and the fourth air outlet hole respectively. The second air outlet hole and the fourth air outlet hole can be used to blow and de-glue the lower end of the glue dispensing head, and the first air outlet hole and the third air outlet hole can be used to blow and de-glue the side wall of the glue dispensing head, so as to blow off the residual glue around the glue dispensing head; The blown-off residual glue falls into the receiving cup. An inner air outlet hole is provided on the side wall of the receiving cup, and an outer air outlet hole is provided on the side wall of the outer shell. The gas continuously introduced into the outer accommodating cavity for blowing off the residual glue will increase the air pressure in the accommodating cavity.

The amount of glue removed in the receiving cup can be observed through the transparent side wall of the outer shell. When a certain amount is accumulated, the clamping assembly is released, and the cover plate and the outer shell are separated, so that the receiving cup can be taken out of the outer shell, which is convenient for cleaning the residual glue in the receiving cup.

[0041] When the air blowing degumming mechanism is adopted, it can simultaneously realize the rapid and effective removal of the residual glue on the lower end of the dispensing head and the lower side wall of the dispensing head, and can improve the uniformity and consistency of the air outlet pressure of each air outlet while ensuring the air outlet pressure of the air outlet, so as to avoid the instantaneous excessive air outlet pressure of a certain air outlet causing damage or adverse interference to the dispensing head, thereby improving the efficiency of removing the residual glue while protecting the dispensing head; further, it can timely release the pressure generated by the high-pressure gas, so as to avoid the residual glue at the lower end of the dispensing head being blown back into the dispensing glue channel due to the instantaneous excessive pressure in the receiving cup, thereby affecting the subsequent dispensing effect.
