[0064] In order to make the technical personnel in the technical field better understand the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described in combination with the drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by the technical personnel in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0065] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0066] See also Figures 1 to 3 The embodiment of the utility model provides a safe glue wiping and cleaning device for a glue dispensing head, comprising: a housing 10, an air motor 20 and an alcohol tank 30. The air motor 20 is installed in the housing 10, and a brush connector 201 is provided on the adapter of the air motor 20; the alcohol tank 30 is used to hold alcohol, and a brush through hole 301 is provided at the bottom of the alcohol tank 30. The brush connector 201 is arranged in the alcohol tank 30 through the brush through hole 301. The air motor 20 is used to drive the brush connector 201 to rotate so as to wipe and clean the glue dispensing head. Specifically, as Figure 1 and Figure 2 As shown in , when cleaning the dispensing head, the dispensing head can be inserted into the alcohol tank 30. When the dispensing head is close to the brush joint 201, the pneumatic motor 20 can drive the brush joint 201 to rotate, and the dispensing head can be cleaned by wiping glue through the rotation of the brush joint 201. Since the alcohol tank 30 is used to hold alcohol, the dispensing head can be better cleaned by alcohol. Since the brush joint 201 is connected to the adapter of the pneumatic motor 20. Therefore, it is necessary to extend into the alcohol tank 30 through the bottom brush through hole 301 of the alcohol tank 30. Since the pneumatic motor 20 drives the adapter to move through the air source, it does not need to be powered by a power supply, so there will be no problem of power short circuit causing alcohol to catch fire. Therefore, it is safer than the method of cleaning the dispensing head by driving the brush joint 201 to rotate by a motor in the prior art, and avoids the safety hazard of alcohol catching fire due to motor short circuit.

[0067] See also Figures 1 to 3 The dispensing head safe glue erasing and cleaning device further includes: an alcohol tank cover 40, the alcohol tank cover 40 is installed at the upper opening of the alcohol tank 30 to block the upper opening of the alcohol tank 30. Figure 1 and Figure 2 As shown in the figure, since the opening of the alcohol tank 30 is relatively large, at room temperature, the alcohol in the alcohol tank 30 may evaporate quickly. In order to prevent the alcohol in the alcohol tank 30 from evaporating quickly, the upper opening of the alcohol tank 30 may be blocked by the alcohol tank cover 40, so that the alcohol volatilization in the alcohol tank 30 may be greatly reduced. At the same time, dust in the factory may also be prevented from entering the alcohol tank 30.

[0068] See also Figures 1 to 3 The alcohol tank cover 40 is provided with a dispensing head inlet 401, which is located directly above the brush connector 201. The dispensing head inlet 401 is used to insert the dispensing head into the brush connector 201 so as to clean the dispensing head by wiping the glue through the brush connector 201. Figure 1 As shown in , since the dispensing head inlet 401 is located directly above the brush joint 201. In this way, after the dispensing head extends from the dispensing head inlet 401 into the alcohol tank 30, the dispensing head can directly reach the brush joint 201. The dispensing head is wiped and cleaned through the brush joint 201. Among them, the size of the dispensing head inlet 401 can be adapted to the size of the dispensing head. In this way, the volatilization of alcohol in the alcohol tank 30 can be reduced.

[0069] See also Figures 1 to 3 The said glue dispensing head safety eraser cleaning device further comprises: a blowing joint 50, said blowing joint 50 is installed on said alcohol tank 30, said blowing joint 50 is used to output flowing gas to dry the alcohol on the glue dispensing head after eraser cleaning. Figures 1 to 3 As shown in FIG, after the brush connector 201 cleans the dispensing head, alcohol may remain on the dispensing head after the brush connector 201 leaves the brush connector 201. After the dispensing head is taken away from the brush connector 201, the air blowing connector 50 may blow air to the dispensing head, and the flow may drive the residual alcohol on the dispensing head to evaporate quickly, so that the dispensing head becomes dry quickly.

[0070] See also Figure 4 and Figure 5 The alcohol tank cover 40 and the air blowing joint 50 are provided with an air inlet 402 at the corresponding position, and the air inlet 402 and the air blowing joint 50 are connected to each other to guide the gas output from the air blowing joint 50 to the position above the brush joint 201. Figure 4 and Figure 5 As shown in , the air blowing joint 50 is installed on one side of the alcohol tank 30. The air output by the air blowing joint 50 can only reach the inner side of the alcohol tank 30, which is too far from the inlet 401 of the dispensing head. The effect of directly drying the dispensing head is not ideal. The air output by the air blowing joint 50 can be further guided to the place close to the inlet 401 of the dispensing head through the air inlet 402 of the alcohol tank cover 40, and then directly output to the dispensing head. When the dispensing head leaves the brush joint 201 through the upper part, the residual glue can be volatilized under the action of the flowing air guided and output by the alcohol tank cover 40, so as to achieve a better drying effect.

[0071] See also Figures 3 to 6 The glue dispensing head safe glue erasing and cleaning device also includes: a glue blowing bottom cover 60, which is fixedly connected to the bottom of the alcohol tank cover 40, and a blowing channel 601 is formed between the upper surface of the glue blowing bottom cover 60 and the alcohol tank cover 40 to guide and output the gas to the top of the brush joint 201. Figures 3 to 6 As shown in , the gas is introduced into the alcohol tank cover 40 by the air inlet 402. The gap between the glue blowing bottom cover 60 and the alcohol tank cover 40 can form a blowing channel 601, and the blowing channel 601 can output the gas along the blowing channel 601, and directly output it to the upper square position of the brush joint 201. In this way, it can act on the glue dispensing head at a close distance, so as to dry the residual alcohol on the glue dispensing head. Since the air outlet gap formed between the glue blowing bottom cover 60 and the alcohol tank cover 40 is an annular structure, the output flow air can act on the four sides of the glue dispensing head, so as to quickly dry the glue dispensing head.

[0072] See also Figure 4 The dispensing head safety glue erasing and cleaning device further includes: a rotating seal ring 70, which is arranged between the alcohol tank 30 and the rotating shaft of the pneumatic motor 20 to seal the gap between the alcohol tank 30 and the pneumatic motor 20. Figure 4 As shown in , since the rotating shaft of the pneumatic motor 20 is arranged in the brush through hole 301 at the bottom of the alcohol tank 30. Therefore, it is necessary to seal the gap between the alcohol tank 30 and the rotating shaft of the pneumatic motor 20 to prevent alcohol from seeping out from the bottom of the alcohol tank 30. The rotating seal ring 70 is arranged between the alcohol tank 30 and the rotating shaft of the pneumatic motor 20, so that the gap between the alcohol tank 30 and the pneumatic motor 20 can be sealed. Since the sealing effect of the rotating seal ring 70 is good, the gap between the rotating shaft and the alcohol tank 30 can be well sealed when the rotating shaft of the pneumatic motor 20 rotates.

[0073] See also Figures 1 to 3 The dispensing head safety glue cleaning device further includes: an alcohol barrel 80 and a water level sensor 90. The alcohol barrel 80 is mounted on the housing 10. The liquid output end of the alcohol barrel 80 is connected to the alcohol tank 30 to replenish alcohol in the alcohol tank 30. Figure 1 and Figure 2 As shown in , the alcohol barrel 80 is installed at a position on one side of the shell 10. The liquid output end of the alcohol barrel 80 can be connected to the liquid input port of the alcohol tank 30 through a connecting pipe, so that the alcohol liquid in the alcohol barrel 80 is introduced into the alcohol tank 30 to replenish the alcohol tank 30. The water level sensor 90 is set at a position on one side of the alcohol tank 30. The water level sensor 90 is used to detect the amount of alcohol in the alcohol tank 30. When the level sensor detects that the amount of alcohol is insufficient, it can send a detection signal to the control host, and the control host controls the alcohol barrel 80 to replenish the alcohol tank 30 with alcohol. As shown in Figure 3 As shown in , the alcohol tank 30 is also provided with a liquid outlet, through which the unclean alcohol in the alcohol tank 30 can be discharged.

[0074] See also Figure 2 and Figure 3 The dispensing head safety glue cleaning device further comprises: an alcohol tank fixing plate 11, and the pneumatic motor 20 is fixedly connected to the housing 10 and the alcohol tank 30 through the alcohol tank fixing plate 11. Figure 2 and Figure 3 As shown in the figure, the alcohol tank 30 and the pneumatic motor 20 can be fixed respectively by the alcohol tank fixing plate 11. The upper part of the alcohol tank fixing plate 11 can be connected and fixed to the alcohol tank 30 by screws, and the lower part of the alcohol tank fixing plate 11 can be fixed to the pneumatic motor 20 by screws. At the same time, the side of the alcohol tank fixing plate 11 can be fixed to the shell 10 by screws, so that the alcohol tank 30, the pneumatic motor 20 and the shell 10 can be relatively locked and fixed to form an integral device.

[0075] See also Figure 2 and Figure 4 The dispensing head safety glue erasing and cleaning device also includes: a transfer block 12, on which are respectively provided an air inlet connector 1201 and an air outlet connector 1202, the air inlet connector 1201 and the air outlet connector 1202 are respectively connected to the air inlet 402 and the air outlet of the pneumatic motor 20, so as to output gas to drive the pneumatic motor 20 to rotate. Figure 2 and Figure 4As shown in , the adapter block 12 is installed at the bottom of the housing 10, and the adapter block 12 is respectively provided with a joint air outlet 1203 and a joint air inlet 1204, and the joint air inlet 1204 can output the gas source introduced by the air inlet joint 1201 to the air inlet 402 of the pneumatic motor 20, and the gas output from the air outlet of the pneumatic motor 20 can be led from the joint air outlet 1203 to the air outlet joint 1202, and discharged from the air outlet joint 1202. The size of the air inlet joint 1201 and the air outlet joint 1202 can be adapted by the adapter block 12 for adapter. Since the size of the air inlet 402 and the air outlet of the pneumatic motor 20 is not compatible with the air inlet joint 1201 and the air outlet joint 1202, the adapter block 12 can be used for corresponding adaptation.
