[0029] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0030] See Figures 1 to 5 This utility model provides a dispensing device 100, which can increase the dispensing volume of the adhesive, eliminate the need for frequent tube replacements, and achieve multi-point dispensing, resulting in higher work efficiency. Furthermore, it provides greater adhesive continuity, reduces the likelihood of air bubbles during dispensing, and improves dispensing quality.
[0031] This utility model embodiment provides a dispensing device 100, including a dispensing box 110 and a plurality of dispensing heads 130. The top side of the dispensing box 110 is provided with at least one pipe connector 150. A colloid receiving cavity 111 is formed inside the dispensing box 110. The pipe connector 150 is connected to the colloid receiving cavity 111 and is used to connect to the colloid pipe on the machine and input colloid into the colloid receiving cavity 111. The bottom side of the dispensing box 110 is provided with a plurality of dispensing slots 113. The plurality of dispensing heads 130 are correspondingly held in the plurality of dispensing slots 113 and are connected to the colloid receiving cavity 111 to discharge the colloid in the colloid receiving cavity 111 respectively, so as to realize dispensing.
[0032] In practical use, the adhesive can be connected to the glue tubing on the machine via the tubing connector 150, allowing glue to be injected into the glue receiving cavity 111, which can hold sufficient glue. Multiple dispensing heads 130 are held in the dispensing slots 113, enabling multi-point dispensing. By adding the glue receiving cavity 111, the dispensing volume of the glue can be increased, eliminating the need for frequent tubing changes. Furthermore, the multi-point dispensing via multiple dispensing heads 130 improves work efficiency. Due to the buffering effect of the glue receiving cavity 111, the glue continuity is higher, reducing the likelihood of air bubbles during dispensing and resulting in better dispensing quality.
[0033] In some embodiments, the dispensing box 110 is further provided with mounting ears 170 at both ends, which are used to detachably fix the dispensing box 110 to the machine base. Specifically, there are two mounting ears 170, which are respectively provided at the left and right ends of the dispensing box 110 and correspond to the mounting points on the machine base to fix the dispensing box 110.
[0034] Furthermore, mounting lugs 170 are integrally disposed at both ends of the top side of the dispensing box 110, and mounting lugs 170 are provided with mounting grooves 171 whose opening direction is away from the pipe connector 150. Specifically, the mounting lugs 170 are provided with open mounting grooves 171, which allow connectors, such as bolts, to be installed in the mounting grooves 171 to fix the mounting lugs 170. The open structure of the mounting grooves 171 also facilitates the installation of bolts on the machine tool. Of course, in other preferred embodiments of this invention, bolts can also be assembled by opening holes in the mounting lugs 170.
[0035] It should be noted that the mounting lug 170 is flush with the top surface of the dispensing box 110, so that the entire surface can fit against the mounting surface on the machine and ensure that the pipe connector can be inserted into the machine and connected to the glue pipe.
[0036] In some embodiments, the pipe connectors 150 include a plurality of pipe connectors 150, which are spaced apart and protrude from the top surface of the dispensing box 110, and are distributed along the same straight line. Specifically, the distribution of the plurality of pipe connectors 150 along the same straight line can correspond to multiple glue pipe openings on the machine, and the arrangement of the plurality of pipe connectors 150 can ensure that the glue flowing into the glue receiving cavity 111 is evenly distributed, avoid local glue concentration, and ensure the dispensing uniformity of each dispensing head 130.
[0037] In some embodiments, the bottom side of the dispensing box 110 is provided with a plurality of dispensing receiving slots, which correspond one-to-one with a plurality of dispensing slots 113. Each dispensing receiving slot is connected to the corresponding dispensing slot 113, and a plurality of dispensing heads 130 are at least partially accommodated in the dispensing receiving slots 115. Specifically, when the dispensing head 130 is engaged with the dispensing slot 113, the bottom end of the dispensing head 130 can extend out of the dispensing receiving slot 115, thereby facilitating dispensing alignment. The dispensing receiving slot 115 can achieve initial positioning when the dispensing head 130 is installed, thereby facilitating the dispensing head 130 to quickly align with the dispensing slot 113 and engage.
[0038] In some embodiments, the dispensing head 130 includes a dispensing body 131, a retaining head 133, and a dispensing nozzle 135. The retaining head 133 is disposed at one end of the dispensing body 131, and the dispensing nozzle 135 is disposed at the other end of the dispensing body 131, communicating with the retaining head 133. The dispensing body 131 is accommodated in a dispensing receiving groove 115, and the retaining head 133 is detachably mounted in the dispensing receiving groove 113 and communicates with the colloid receiving cavity 111. Specifically, the retaining head 133 protrudes from the top end of the dispensing body 131 and is correspondingly retained in the dispensing receiving groove 113, while the dispensing nozzle 135 is disposed at the bottom end of the dispensing body 131 and protrudes downward. In actual assembly, the retaining body can be inserted into the dispensing receiving groove 115, with the retaining head 133 at the top end correspondingly retained in the dispensing receiving groove 113, and the dispensing nozzle 135 at the bottom end extending out of the dispensing receiving groove 115.
[0039] It should be noted that in this embodiment, a dispensing channel is formed inside the dispensing body 131. One end of the dispensing channel extends to the holding head 133, and the other end extends to the dispensing nozzle 135, thereby facilitating the smooth flow of the adhesive.
[0040] In some embodiments, the dispensing receiving groove 115 is rectangular, and the width of the dispensing receiving groove 115 is adapted to the width of the dispensing body 131, while the length of the dispensing receiving groove 115 is adapted to the distance between the distal ends of the retaining head 133 and the dispensing nozzle 135. Specifically, the width of the dispensing receiving groove 115 refers to the width of its shorter side, and the length of the dispensing receiving groove 115 refers to the width of its longer side. The distance between the distal ends refers to the distance between the end of the retaining head 133 furthest from the dispensing nozzle 135 and the end of the dispensing nozzle 135 furthest from the retaining head 133, indicating the maximum length of the dispensing head 130. By limiting the dimensions of the dispensing receiving groove 115, during actual assembly, when the retaining head 133 is held in the dispensing groove 113, the dispensing body 131 is interference-fitted into the dispensing receiving groove 115, ensuring a positioning effect, such as... Figure 2When the corresponding dispensing head 130 does not need to dispense glue, it can be horizontally inserted into the dispensing receiving groove 115. At this time, the dispensing body 131 is still interference-fitted into the dispensing receiving groove 115, and its side can seal against the corresponding dispensing slot 113 to prevent glue leakage from the corresponding dispensing slot 113. Figure 3 This design allows for flexible adjustment of the effective dispensing quantity of the dispensing head 130, extending its service life and further preventing frequent replacements.
[0041] In some embodiments, the dispensing nozzle 135 is conical, and the outer diameter of the dispensing nozzle 135 gradually decreases in the direction away from the retaining head 133. Specifically, the conical shape of the dispensing nozzle 135 enables better and more precise positioning of the dispensing position.
[0042] In some embodiments, a plurality of dispensing accommodating slots 115 and a plurality of pipe connectors 150 are respectively disposed on the upper and lower sides of the dispensing box 110. Preferably, there can be three dispensing accommodating slots 115 and three pipe connectors 150, with the three pipe connectors 150 and the three dispensing accommodating slots 115 respectively distributed on the upper and lower sides of the dispensing box 110.
[0043] This utility model embodiment also provides a dispensing device, including a machine base and the aforementioned dispensing apparatus 100. The dispensing apparatus 100 includes a dispensing box 110 and a plurality of dispensing heads 130. At least one pipe connector 150 is provided on the top side of the dispensing box 110. A colloid receiving cavity 111 is formed inside the dispensing box 110. The pipe connector 150 is connected to the colloid receiving cavity 111 for connecting to a colloid pipe on the machine base and inputting colloid into the colloid receiving cavity 111. A plurality of dispensing slots 113 are provided on the bottom side of the dispensing box 110. The plurality of dispensing heads 130 are correspondingly held in the plurality of dispensing slots 113 and communicate with the colloid receiving cavity 111 for discharging the colloid from the colloid receiving cavity 111, thereby achieving dispensing. The machine base and the dispensing box 110 are detachably connected, and the pipe connector 150 is connected to a colloid pipe on the machine base.
[0044] In summary, the dispensing device 100 and dispensing equipment provided in this embodiment of the present invention have a colloid receiving cavity 111 inside the dispensing box 110, and a pipe connector 150 on the top side of the dispensing box 110. Colloid is injected into the colloid receiving cavity 111 through the pipe connector 150. Multiple dispensing slots 113 are provided on the bottom side of the dispensing device, and multiple dispensing heads 130 are correspondingly held in the multiple dispensing slots 113 and communicate with the colloid receiving cavity 111, thereby discharging the colloid from the colloid receiving cavity 111 and realizing dispensing. Compared with the prior art, this invention, by adding the colloid receiving cavity 111, can increase the dispensing volume of the colloid, eliminating the need for frequent replacement of the colloid pipe. At the same time, the multiple dispensing heads 130 enable multi-point dispensing, resulting in higher work efficiency. Furthermore, due to the buffering effect of the colloid receiving cavity 111, the continuity of the colloid is higher, air bubbles are less likely to form during dispensing, and the dispensing quality is better.
[0045] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
