The embodiment provides a dispensing head which can be applied to dispensing equipment. During the operation of the dispensing device, the dispensing head can be moved to a specific position and controlled by a pneumatic valve or a piezoelectric valve to apply glue at a preset position on the target. The target object can be a micro display screen or a structural member such as glass.
As shown in fig. 1 to 6, the dispensing head includes a body 100. The body 100 may be formed with a glue inlet 110 and a dispensing hole set 130 that are connected to each other. In an embodiment, the glue inlet holes 110 and the distribution hole sets 130 may both extend in the axial direction of the body 100. In an embodiment, the axial direction of the body 100 may refer to an extending direction of the axis L.
In addition, a special-shaped glue outlet set 120 is further disposed on an end surface of the body 100, and the glue outlet set 120 can be located on an end surface of the body 100 that is far away from the glue inlet hole 110. Wherein, the irregular shape may refer to a shape other than a conventional ellipse or rectangle, such as a snowflake shape, a pentagram shape, and the like. In an embodiment, the specific shape of the glue outlet group 120 may be set according to the shape of the preset position on the target, and the shape of the glue outlet group 120 may be the same as the shape of the preset position on the target. The shape of the glue outlet set 120 may include the shape type and size of the glue outlet set 120.
In one embodiment, the glue outlet set 120 may communicate with an end of the dispensing hole set 130 away from the glue inlet hole 110. That is, the glue outlet set 120 may communicate with the glue inlet hole 110 through the dispensing hole set 130.
In an embodiment, the projection of the glue outlet set 120 coincides with the projection of the dispensing hole set 130 on a plane perpendicular to the axial direction of the body 100. That is, the cross-sectional shape of the glue outlet set 120 is the same as the cross-sectional shape of the dispensing hole set 130. The cross-sectional shape of the glue outlet set 120 and the cross-sectional shape of the dispensing hole set 130 are both perpendicular to the axial direction of the body 100.
The inventors have found that the shape of the glue outlet set 120 in the related art is generally not consistent with the shape of the distribution hole set 130, and the area of the glue outlet set 120 is larger than the area of the cross section of the distribution hole set 130. Therefore, in the process of applying glue through the dispensing head, the glue is generally required to flow transversely (i.e. in a direction perpendicular to the axial direction of the body 100) to fill the preset position of the target object, which will certainly increase the time for applying the glue, and cannot ensure the uniformity of the glue at each part of the preset position, and is easy to generate air bubbles.
In the application, in the process of coating glue by using the dispensing head, the glue can enter the body 100 through one end of the glue inlet 110 far away from the distribution hole group 130, and the glue can flow to the glue outlet group 120 through the glue inlet 110 and the distribution hole group 130 in sequence. In the present application, the cross-sectional shape of the dispensing hole set 130 is the same as the cross-sectional shape of the glue outlet set 120, and the shape of the glue outlet set 120 is the same as the shape of the preset position on the target. In the process of coating glue through the glue dispensing head, the glue dispensing head can directly output the glue with the same shape as the preset position, and the glue can simultaneously contact each part of the preset position, so that the glue can be directly spread on the preset position of the target object. On the target, the glue does not need to flow laterally (i.e. perpendicular to the axial direction of the body 100) to fill the preset position.
Therefore, compare in the correlation technique, the dispensing head that this application provided can promote the efficiency of coating glue, promotes gluey efficiency promptly, simultaneously, also can promote the even uniformity of predetermineeing each position glue in position, reduces the production of bubble. Furthermore, the coating quality of glue can be improved, and the yield and quality of corresponding products can be improved.

As shown in fig. 1, the dispensing head may include a body 100. The body 100 may include a first end 101 and a second end 102.
Referring to fig. 2, the body 100 further has a glue inlet 110 and a dispensing hole set 130. Wherein the glue wells 110 may be located near the first end 101 with respect to the set of dispensing wells 130, and the set of dispensing wells 130 may be located near the second end 102 with respect to the glue wells 110.
In an embodiment, the end surface of the body 100 near the first end 101 may further be provided with a glue inlet 140. The glue inlet 140 may be in communication with an end of the glue inlet hole 110 remote from the set of dispensing holes 130. During use of the dispensing head, glue may enter the glue inlet hole 110 through the glue inlet 140.
As shown in fig. 2, in some embodiments, the cross-sectional area of the glue inlet hole 110 gradually decreases from the end of the glue inlet hole 110 near the glue inlet 140 to the end of the glue inlet hole 110 near the distribution hole set 130. The cross-sectional area of the glue inlet hole 110 may refer to an area of a cross-section of the glue inlet hole 110 perpendicular to the axial direction of the body 100. That is, the glue inlet hole 110 may have an inverted cone-shaped structure. Therefore, after the glue enters the glue inlet 110 from the glue inlet 140, the glue can gradually converge towards the position of the distribution hole group 130, so that the glue can enter the distribution hole group 130, the glue in the glue inlet 110 can be ensured to flow towards the position of the distribution hole group 130 as much as possible, and the residue of the glue in the glue inlet 110 can also be reduced.
In some embodiments, the glue inlet 110 may have an inverted conical structure.
In other embodiments, the glue inlet hole 110 may also have an inverted triangular pyramid shape, a rectangular pyramid shape, or a pentagonal pyramid shape.

The glue outlet set 120 may be in communication with an end of the dispensing hole set 130 remote from the glue inlet hole 110. The shape of the glue outlet set 120 can be set according to the shape of the preset position on the target object.
Referring again to FIG. 1, in some embodiments, the predetermined locations on the target may be snowflake-shaped. Accordingly, the glue outlet set 120 may be snowflake-shaped.
In some embodiments, the glue outlet set 120 may include a first glue outlet 121. The set of dispensing orifices 130 can include a first dispensing orifice 131. One end of the first dispensing hole 131 far from the glue inlet hole 110 may be communicated with the first glue outlet 121, and the other end of the first dispensing hole 131 is communicated with the glue inlet hole 110. The other end of the first distributing hole 131 may refer to an end of the first distributing hole 131 close to the first end 101 of the body 100.
On a plane perpendicular to the axial direction of the body 100, the projection of the first glue outlet 121 is snowflake-shaped, the projection of the first distribution hole 131 is snowflake-shaped, and the projection of the first distribution hole 131 coincides with the projection of the first glue outlet 121.
In other embodiments, as shown in fig. 3 and 4, the first glue outlet 121 may also be cross-shaped. Correspondingly, on a plane perpendicular to the axial direction of the body 100, both the projection of the first glue outlet 121 and the projection of the first distribution hole 131 may be cross-shaped, and the projection of the first distribution hole 131 may coincide with the projection of the first glue outlet 121.
In other embodiments, the shape of the first glue outlet 121 may also be a concave polygon such as a pentagram or a hexagram. On a plane perpendicular to the axial direction of the body 100, the projection of the first glue outlet 121 and the projection of the first dispensing hole 131 may be both a concave polygon such as a square, a pentagram, or a hexagon star, and the projection shape of the first dispensing hole 131 is the same as the projection shape of the first glue outlet 121, and accordingly, the projection of the first glue outlet 121 coincides with the projection of the first dispensing hole 131.
Of course, in other embodiments, on a plane perpendicular to the axial direction of the body 100, the projection of the first glue outlet 121 and the projection of the first dispensing hole 131 may be both a convex polygon such as a pentagon or a hexagon, and the shape of the projection of the first dispensing hole 131 is the same as the shape of the projection of the first glue outlet 121, and accordingly, the projection of the first glue outlet 121 coincides with the projection of the first dispensing hole 131. It can be understood that, on a plane perpendicular to the axial direction of the body 100, the projection shape of the first glue outlet 121 is the same as the shape of the preset position on the target.
In some embodiments, the diameter of the outer circle of the first glue outlet 121 may be set to 0.1mm to 5.0mm, so that the dispensing head may be suitable for the micro-display structure processing process. Illustratively, the diameter of the outer circle of the first glue outlet 121 may be set to any one of 0.1mm, 0.85mm, 1.2mm, 1.35mm, 1.6mm, 2.15mm, 2.5mm, 2.85mm, 3.3mm, 3.75mm, 4.1mm, 4.55mm, 4.95mm, or 5.0mm, and 0.1mm to 5.0 mm.
In the process of using the dispensing head, the first glue outlet 121 of the dispensing head can be opposite to the preset position on the target object. In one embodiment, the glue output from the first glue outlet 121 may be snowflake-shaped, so that the glue can be directly spread over the predetermined position of the target. During this process, the glue does not need to flow laterally in the preset position. Furthermore, the time for coating the glue can be saved, the uniform consistency of the glue on each part of the preset position can be ensured, and the generation of bubbles is reduced.

The second glue outlets 122 are spaced apart from each other and arranged on an end surface of the body 100 close to the second end 102. Accordingly, the distribution hole group 130 may include a plurality of second distribution holes 132 arranged side by side, and the second distribution holes 132 are each parallel to the axial direction of the body 100.
In an embodiment, the number of the second glue outlets 122 is the same as the number of the second distribution holes 132.
