[0001] The utility model relates to the technical field of encapsulation glue painting, in particular to a glue painting needle head fixing bracket. Background Art

[0002] In the existing encapsulation process, products are cured and bonded with glue. The glue painting needle head extrudes a fixed amount of glue through equipment to control the air pressure and coats it on the surface of the product. Usually, the glue painting needle head is first installed on the glue tube, and then the glue tube is manually fixed on the bracket, and there will be deviations in the installation height. At the same time, during the glue painting process, the glue painting needle head is suspended to coat the glue, and the risk of being touched is very high, resulting in the center deviation of the glue painting needle head and affecting the stability of glue painting. On the other hand, when replacing the new glue, it is necessary to manually drain the glue to squeeze out the air bubbles, and then the glue painting needle head needs to be cleaned, which will also cause the center deviation of the glue painting needle head. In addition, when squeezing the glue through air pressure, the acting force applied by the air easily causes the displacement of the glue tube, thereby driving the change of the height of the glue painting needle head and resulting in abnormal glue painting height.

Figure 2 is a schematic structural view of another glue painting needle head fixing bracket provided by an embodiment of the present utility model, in combination with Figure 1 and Figure 2 as shown, the glue painting needle head fixing bracket includes a fixing base 1 and a fixing block 2. Further, Figure 3 is a schematic structural view of a fixing base provided by an embodiment of the present utility model. Figure 4 is a schematic structural view of the fixing base from another perspective provided by an embodiment of the present utility model, in combination with Figure 3 and Figure 4 as shown, a first receiving groove 11 is provided on the fixing base 1, and a first positioning hole 12 is provided at the bottom of the first receiving groove 11, that is, the first positioning hole 12 provided on the fixing base 1 communicates with the first receiving groove 11 through the bottom of the first receiving groove 11. Further still, Figure 5 is a schematic structural view of a fixing block provided by an embodiment of the present utility model. Figure 6 is a schematic structural view of the fixing block from another perspective provided by an embodiment of the present utility model, in combination with Figure 5 and Figure 6As shown, the fixing block 2 includes a main body portion 21 and a positioning portion 22 formed by a protrusion at the bottom of the main body portion 21. A second receiving groove 23 is provided on the fixing block 2, and a second positioning hole 24 communicating with the second receiving groove 23 is provided at the bottom of the positioning portion 22. Figure 7 It is a schematic structural view of another perspective of a glue drawing needle fixing bracket provided by an embodiment of the present invention. Combining Figures 1 to 7 As shown, the main body portion 21 is fixedly arranged in the first receiving groove 11, and the positioning portion 22 is positioned in the first positioning hole 12. Thus, the main body portion of the glue drawing needle can be fixed in the second receiving groove 23, and the tip portion of the glue drawing needle can be exposed through the second positioning hole 24, thereby realizing the fixation of the glue drawing needle by the glue drawing needle fixing bracket to maintain the coating direction. On the other hand, the glue drawing needle fixing bracket can be directly installed on the original glue drawing equipment without modifying the original glue drawing equipment, and the disassembly and assembly are convenient and fast, and excellent process optimization benefits can be obtained at low cost.

[0034] It should be noted that the size of the first receiving groove 11 matches the size of the main body portion 21, so that the fixing base 1 and the fixing block 2 can be relatively fixed by the way of machining tolerance limitation. Similarly, the size of the second receiving groove 23 matches the size of the glue drawing needle, so that the fixing block 2 can fix the glue drawing needle by the way of machining tolerance limitation. It should be further noted that the bottom of the first receiving groove 11 can limit the fixing block 2, and at the same time, the bottom of the second receiving groove 23 can limit the glue drawing needle, so that the pressure during air pressure extrusion of the glue drawing equipment can be offset to prevent the glue drawing needle from moving downward.

[0035] In one embodiment, the fixing base 1 and the fixing block 2 are made of metal, so as to ensure the connection strength between the glue drawing needle fixing bracket and the glue drawing equipment and the reliability of the fixing of the glue drawing needle by the glue drawing needle fixing bracket.

It is easy to understand that by providing the second chamfer 221 on the fixing block 2, burrs can be removed to prevent damage to the fixing seat 1 and the glue needle, and it can also play a guiding and positioning role when assembling the glue needle and the fixing block 2.

[0042] Combination Figure 5 and Figure 8 As shown, in one embodiment, a step structure 231 is provided in the second receiving groove 23. That is, the size of the second receiving groove 23 decreases stepwise from top to bottom to adapt to the structure of the painting glue needle, so that the painting glue needle can be easily installed and fixed through the lower area of ​​the second receiving groove 23.

[0043] It should be noted that, in order to facilitate locking of the fixing block 2, the bearing portion 14 and the first receiving groove 11 are based on a rectangular structure, that is, the bearing portion 14 is a rectangular parallelepiped structure as a whole, and the first receiving groove 11 is a rectangular groove as a whole. Similarly, in order to facilitate locking of the painting glue needle, the lower part of the second receiving groove 23 is a rectangular groove as a whole. As an optional embodiment, in order to match the conical painting glue needle, the bearing portion 14 can be set as a cylindrical structure, and the first receiving groove 11 and the second receiving groove 23 can be set as circular grooves.

[0044] CombinationFigure 5 and Figure 8 As shown, in one embodiment, the cross-section of the main body portion 21 is set as a rotationally symmetric figure. That is to say, the fixing block 2 can be rotated to different angles for installation, so as to achieve the function of adjusting the installation angle, in order to enrich the application scenarios of the glue painting needle fixing bracket. Exemplarily, in combination with Figure 1 and Figure 5 shown, the cross-section of the main body portion 21 is set as a segment shape, specifically including two opposite straight edges and two opposite arc edges, so that the main body portion 21 forms two opposite planes and two opposite arc surfaces. Further, when the fixing block 2 is installed on the fixing seat 1, the two planes of the main body portion 21 are attached to two opposite side walls in the first receiving groove 11, and the two arc surfaces are partially abutted against the other two opposite side walls in the first receiving groove 11. Thus, the fixing block 2 can be fixed through the first receiving groove 11 and can be rotated 180 degrees to achieve the adjustment of the installation angle.

[0045] In combination with Figure 2 and Figure 8 shown, in one embodiment, the cross-section of the main body portion 21 is set as a regular hexagon, so that the main body portion 21 forms six planes. Further, when the fixing block 2 is installed on the fixing seat 1, the two opposite planes of the main body portion 21 are attached to two opposite side walls in the first receiving groove 11, and the two opposite edges are abutted against the other two opposite side walls in the first receiving groove 11. Thus, the fixing block 2 can be fixed through the first receiving groove 11 and can be rotated 60 degrees to achieve the adjustment of the installation angle.

[0046] In combination with Figure 3 and Figure 4 shown, in one embodiment, two avoiding grooves 112 are recessed on two opposite side walls in the first receiving groove 11. It should be noted that a first fastening through hole 141 is provided at the bottom of the avoiding groove 112. It should be further noted that when the two opposite planes of the main body portion 21 are attached to the two side walls in the first receiving groove 11, a certain gap is formed between these two opposite planes and the avoiding groove 112, which helps to form an avoidance when the fixing block 2 is fixed by a bolt through the first fastening through hole 141, so as to ensure the reliability of the fixing structure.
