Description
Technical Field
The invention relates to the field of glue dispensing, in particular to a glue dispensing process with high viscosity and precise film width requirement, and more particularly relates to a glue hanging prevention gas auxiliary atomization device capable of controlling height and further controlling spray film width.
Background
The dispensing equipment is the process equipment widely used in mechanical production and processing at present, and the application range of the dispensing equipment covers the processes of bonding, encapsulating, coating, sealing, filling, dropping, scribing, gluing and the like of products. The effects of water resistance, light leakage prevention, heat conduction, electric conduction, bonding, dust prevention, encapsulation, reinforcement and the like can be achieved. The glue dispensing is divided into the following steps: and (4) contact dispensing and non-contact dispensing. The contact type glue dispensing is to use a certain pressure to push glue to pass through needle heads with different inner diameters so as to achieve the purpose of glue dispensing. The non-contact type glue dispensing is to act on glue water in a certain mode, so that the kinetic energy of the glue water is increased and the glue water is further sprayed to an acting position. The non-contact glue dispensing valve mainly comprises an injection valve and an atomization valve, wherein the injection valve controls the opening and closing of a pintle through air pressure and a spring, and the glue is sprayed to a specified position in a point form. The spray valve atomizes the glue into numerous tiny particles by means of air and moves to the target location.
With the widespread use of high-precision instruments in recent years, there has been a growing demand for precision coating of devices such as highly integrated circuit boards. As in the mobile phone industry, electronic device components are designed as two layers, or even three layers, for higher integration. This places higher demands on the insulation and fixation between component layers. The spraying valve used at present uses a bypass air channel outside the glue pipe, and the bypass air channel is fixed at a fixed position below the glue nozzle. There are the following problems: 1) at the end of the spraying, the nozzle can hang glue, and at the initial stage of the next circulation spraying, the glue hung on the glue head can be firstly sprayed to a target position to generate a large head (as shown in figure 1), so that the glue discharging stability is influenced; 2) the width of the glue is not adjustable, and multiple times of glue dispensing is often needed; 3) before this, atomizing air flue below all is the plane, and gas can produce the whirl after hitting the wall, blows glue backward to the bypass air flue in, blocks up the air flue, further worsens the atomizing effect.

the adjusting assembly is provided with an adjusting screw rod 1 and a fixing piece; the fixing piece is sleeved on the outer wall of the atomizing cap 6, and the adjusting screw rods 1 are arranged in adjusting screw holes at two ends of the fixing piece;

Preferably, a plurality of flow stabilizing air passages are uniformly arranged in the flow stabilizing plug 5, and the number of the flow stabilizing air passages is a positive even number.
Preferably, the steady flow air passage is of a circular arc structure.
Preferably, the steady flow air flue forms a convex strip in a protruding mode towards the direction of the outer wall of the steady flow plug 5, and a gap does not exist at the contact position of the outer wall of the convex strip and the inner wall of the atomization cap.
Preferably, the glue outlet pipe 4 is of a hollow structure, the end part of the glue outlet pipe 4 extending into the atomizing cap 6 is conical, and a glue outlet hole is formed in the center of the end part of the glue outlet pipe 4.
Preferably, the side wall of the air inlet cap 2 is provided with an air inlet hole; and a male thread structure is arranged at the end part of the air inlet cap 2 connected with the atomizing cap 6, and the diameter of the male thread structure is increased from small to large.
Preferably, the end part of the atomizing cap 6 connected with the end part of the air inlet cap 2 is provided with a female thread structure, and the male thread structure is matched with the female thread structure.
Preferably, the outer wall of the atomizing cap 6 is provided with a concave portion, and the fixing member is sleeved on the outer wall of the concave portion.
Preferably, the other end of the atomizing cap 6 is provided with a glue outlet.
Preferably, the inside of the other end of the atomizing cap 6 is an arc-shaped groove, and the arc-shaped groove and the other end of the flow stabilizing plug 5 form an atomizing cavity.
The working principle is as follows: the glue injection machine extrudes glue to a glue outlet nozzle flow 3, enters a glue outlet pipe 4 and flows out of a glue outlet hole through an atomization cavity A;
in order to prevent the glue from generating a large head B due to the redundant glue in the glue outlet nozzle 3 in the next glue outlet process, the glue hung on the glue head is firstly sprayed to a target position, so that an infinite loop is formed; therefore, in the glue discharging process, gas with corresponding air pressure is injected from the air inlet hole of the air inlet cap 2 by an air pump and other similar equipment, the gas is divided into stable atomized gas through the steady flow air passage of the steady flow plug 5, and after glue injection is finished, redundant glue hung at the end part of the glue discharging pipe 4 at the atomizing cavity is blown away, so that the aim that the glue discharging nozzle 3 does not have redundant glue at the initial stage of the next spraying cycle is fulfilled.
In the above embodiment, the flow stabilizing plugs 5 play a great role, even number of flow stabilizing air passages are uniformly arranged, and the interface of the flow stabilizing air passages is preferably in the shape of an arc. The gas with certain turbulence passing through the steady flow air passage can be rectified again, and the even number of the gas passages are uniformly arranged, so that the partial atomization phenomenon caused by asymmetric airflow can be eliminated. The conventional structure without the flow stabilizing plug 5 and the internal basin with the flow stabilizing plug 5 were analyzed by performing a streamline simulation. The flow stabilizing effect of the flow stabilizing plug 5 is very obvious, and the gas flow cross section area is reduced, so that the gas speed is improved to a certain extent, and the atomization effect is better.
Glue width and adjust structure and effect:
the film width of the atomized glue is mainly controlled by connecting the adjusting screw rod 1 (the adjusting screw rod can be driven by manual rotation of the adjusting screw rod or motor rotation) and the height of the atomizing cap 6. The height of the atomizing cap 6 directly affects the film width of the spray. When atomization is not needed, the atomization cap 6 can be lifted through rotation of the adjusting screw rod 1, so that the lower end of the rubber outlet pipe 4 is flush with the outlet of the flow stabilizing plug 5. When glue needs to be atomized, the atomizing cap 6 is moved to the position below the outlet of the flow stabilizing plug 5 by rotating the adjusting screw rod 1, atomized air can be stabilized and accelerated by the flow stabilizing plug 5, and the glue is atomized. In actual use, the film width of glue which is often needed can be changed, and by using the device provided by the invention, the film width can be adjusted by adjusting the height of the atomizing cap 6, so that the requirement is met. The invention can also deal with more complex dispensing environments, wherein black is components which can not be dispensed, and blue is atomized glue which can be achieved by the invention. The glue dispensing equipment with different glue widths is not required to be used for dispensing for multiple times, and the production efficiency of products is greatly improved.
The technical features mentioned above are combined with each other to form various embodiments which are not listed above, and all of them are regarded as the scope of the present invention described in the specification; also, modifications and variations may be suggested to those skilled in the art in light of the above teachings, and it is intended to cover all such modifications and variations as fall within the true spirit and scope of the invention as defined by the appended claims.
