Abstract
The utility model relates to the technical technology of glue dripping devices, in particular to a glue dripping head for the glue dripping device. The utility model comprises the main body of a hollow glue dripping head; a top face thereof is formed into a convex block, and the convex block is provided with a glue dripping hole which is communicated with the inner cavity of the main body; the top face of the convex block is provided with two guard blocks, and two guard blocks are respectively positioned on both sides of the central connecting lines of the two glue dripping holes. The central distance of the two glue dripping holes are 0.65 mm. By adopting this structure, the exterior shape of the prior glue dripping head is changed for making the prior glue dripping head be suitable to the producing process of the pre-requisition AI working. The tin flowing phenomenon of the components which is in a chip adhering process after wave soldering can be improved at the same time; the distance of the glue dripping hole can be shortened for making the glue form after the glue dripping separate and convert into the mode of two points in a line; the tin flowing phenomenon can be eliminated, and the ability of the producing process can be promoted.
Description
Technical field:
The utility model relates to the point gum machine equipment technical field, especially refers to a kind of Glue dripping head that is used for point gum machine.
Background technology:
At present, in the circuit board process of electric product, need to use point gum machine that element point glue is fixed.At present comparatively general is the point gum machine that PANASONIC is produced.See accompanying drawing 1, this is the stereogram of Glue dripping head in the point gum machine produced of present PANASONIC, it comprises a Glue dripping head main body 31, be formed with a projection 32 at its top, and on projection 32, be formed with the cylinder 33 of two hollows, the through hole of being offered in this cylinder 33 is a glue hole 34, and the centre-to-centre spacing in these 2 glue holes 34 is 0.8 millimeter.In addition, be formed with protective device 35 in the both sides of projection 32.As everyone knows, since the restriction of its structure, the inapplicable processing procedure that intensive preposition AI (automatic insertion) operation is arranged of the Glue dripping head of this kind Panasonic point gum machine.This brings very big puzzlement just for the product development that preposition AI operation is arranged, the miniaturization design of product.See accompanying drawing 2, this is Panasonic's Glue dripping head forms glue point 37 behind some glue on the circuit board 26 a schematic diagram, because it is bigger to put the spacing in glue hole 34, two glue point separately, this shape glue point is in the attachment process of chip, element is prone to the phenomenon of string tin behind the wave-soldering processing procedure, influenced the quality of product.
Summary of the invention:
The utility model provides a kind of and can not only adapt to the processing procedure that preposition AI operation is arranged just in order to overcome the shortcoming of above-mentioned product, and can assist to improve in the chip attachment process element in the string tin phenomenon behind the wave-soldering processing procedure, to promote product processing procedure ability.
The technical scheme that the utility model adopted is: its Glue dripping head main body by hollow constitutes; its end face is formed with a projection; and offer the some glue hole that communicates with the body interior cavity on this projection; the end face of projection is formed with two protection pieces, and these two both sides of protecting piece to lay respectively at 2 glue hole lines of centres.
The centre-to-centre spacing in above-mentioned 2 glue holes is 0.65 millimeter.
After adopting this structure,, make it can adapt to the processing procedure that preposition AI operation is arranged by change to original Glue dripping head outer shape.Simultaneously for improving the string tin phenomenon of element behind wave-soldering in the chip attachment process, some glue pitch-row is from also shortening, and makes the glue shape behind the glue separately become 2 connection being aligneds by former 2, to overcome string tin phenomenon, promotes the processing procedure ability.
Description of drawings:
Fig. 1 is the structural representation of existing product;
Fig. 2 is a glue point schematic diagram behind the existing product point glue;
Fig. 3 is a stereogram of the present utility model;
Fig. 4 is a cutaway view of the present utility model;
Fig. 5 is a partial enlarged drawing of the present utility model;
Fig. 6 is the schematic diagram of glue point behind the utility model point glue.
The specific embodiment:
The utility model is at the existing deficiency of present Panasonic Glue dripping head, and its structure is improved and a kind of Glue dripping head of being proposed.See Fig. 3～5, it mainly is that Glue dripping head main body 1 by hollow constitutes, and is formed with a projection 11 at main body 1 end face, and the some glue hole 12 that communicates with the body interior cavity is opened on this projection 11.End face at projection 11 also is formed with two protection pieces 13, and this protection piece 13 lays respectively at the both sides of 2 glue hole 12 lines of centres.And the cross section of this protection piece 13 is that isosceles are trapezoidal.
After adopting this structure, the utility model is simplified the external structure of Glue dripping head greatly, makes it applicable to the processing procedure that intensive preposition AI operation is arranged.Simultaneously present relatively Panasonic's Glue dripping head, the centre-to-centre spacing in its 2 glue holes 12 is 0.65 millimeter.See accompanying drawing 6, this is the schematic diagram that forms glue point 21 behind the present embodiment point glue on circuit board 2, and owing to dwindling of distance between the some glue hole 12, two glue points 21 of its formation are connected as a single entity, and form the shape of a similar peanut.So,, can assist to improve the string tin phenomenon of chip attachment process element behind wave-soldering, promote the processing procedure ability by an improvement of glue hole 12 distances.
After the utility model adopted this structure, it was applicable to the point gum machine of the processing procedure that preposition AI operation is arranged, and elimination quality suffering, and through experiment, it promotes processing procedure ability and has reached 6 Sigma's process conditions, and the quality of product is greatly improved.
