Description

Technical Field

[0001] The utility model belongs to the technical field of gluing, in particular to a gluing mechanism for preventing material sedimentation. Background Art

[0002] In modern industrial production, gluing is a key process for connection, sealing, and protection, and is widely used in electronics, automobiles, aerospace, construction and other fields. The performance and stability of the gluing mechanism, as the core equipment of the gluing process, directly affect the final quality and production efficiency of the product. The existing gluing mechanism is often automatic, and the glue will flow out and spray out from the glue storage cylinder under the blowing of high-pressure airflow to achieve gluing.

[0003] However, in order to improve the performance of the glue, other materials are often added to the glue. These materials are evenly distributed in the glue after being fully mixed. Since the amount of glue applied each time is small and the machine needs to be supervised by the operator, after a long period of gluing or the production line is stopped, the materials will settle at the bottom of the glue due to long-term standing, affecting the performance of the glue.

[0015] Figure 2 is Figure 1 a vertical sectional view of the glue coating mechanism for preventing material precipitation. Detailed Description of the Embodiment

[0016] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the structure of the glue coating mechanism for preventing material precipitation of the present utility model. As Figure 1 and 2 shown, the glue coating mechanism for preventing material precipitation includes a glue spraying device 10 and two glue storage devices 20 symmetrically arranged on both sides of the glue spraying device 10. The glue coating mechanism for preventing material precipitation further includes some other functional modules, such as a power distributor and a controller connected to the glue spraying device 10, etc., which should be well-known technologies to those skilled in the art and will not be described in detail herein one by one.

[0017] The glue spraying device 10 includes a receiving cavity 11, a glue outlet channel 12 provided at one end of the receiving cavity 11 and communicating with the receiving cavity 11, a adapter 13 provided at the end of the glue outlet channel 12, a push rod 14 movably inserted into the glue outlet channel 12, an air inlet 15 provided on the receiving cavity 11, two glue inlets 16 provided at one end of the receiving cavity 11, and a back plate 17 provided on one side of the receiving cavity 11.

[0018] The receiving cavity 11 is used to accommodate the push rod 14 and can accommodate excess unextruded glue. The receiving cavity 11 is a closed cavity.

[0019] The extending direction of the glue outlet channel 12 is the same as that of the receiving cavity 11, both extending in the vertical direction. The glue outlet channel 12 is located at the bottom of the receiving cavity 11.

[0020] The adapter 13 is sleeved on the glue outlet channel 12. After the glue flows out of the glue outlet channel 12, it enters the adapter 13. The adapter 13 is used to set a nozzle. The shape of the nozzle (not shown in the figure) is well-known to those skilled in the art and will not be elaborated here, and it is not shown in the figure.

[0021] One end of the push rod 14 is provided with a linear drive assembly 141 to drive the push rod 14 to move in the glue outlet channel 12. The cross-sectional shape of the push rod 14 is the same as that of the glue outlet channel 12. The push rod 14 is selectively inserted into the glue outlet channel 12 under the drive of the linear drive assembly 141, closing the glue outlet when inserted into the glue outlet channel 12 and opening the glue outlet when pulled out of the glue outlet channel 12.

[0022] The air inlet 15 is communicated with a high-pressure air source. When the glue outlet channel 12 is opened, high-pressure gas will flow into the receiving cavity 11 from the air inlet 15 and spray out from the glue outlet channel 12.

[0023] The glue inlets 16 are symmetrically arranged on both sides of the receiving cavity 11 and communicate with the receiving cavity 11. Each glue inlet 16 is respectively communicated with a glue storage device 20. When the glue outlet channel 12 is opened, high-pressure gas will carry the glue and spray it out from the glue outlet channel 12 to achieve glue coating.

[0024] The back plate 17 is connected to the receiving cavity 11 and the linear drive assembly 141 of the push rod 14 to facilitate the stable installation and positioning of each component.

[0025] When spraying glue, the linear drive assembly 141 is controlled to move the push rod 14 out of the glue outlet channel 12, and high-pressure gas is blown into the air inlet 15. The high-pressure gas will flow out from the glue outlet channel 12 and carry the glue liquid flowing into the accommodation cavity 11 from the glue inlet 16, thereby realizing glue spraying.

[0026] Each glue storage device 20 includes a glue storage cylinder 21 respectively arranged on one side of the accommodation cavity 11, two sensors 22 arranged on the glue storage cylinder 21, a sealing cover 23 arranged on the top of the glue storage cylinder 21, and an air valve 24 arranged on the sealing cover 23.

[0027] The glue storage cylinder 21 includes a cylinder body 211, an opening 212 arranged on the top of the cylinder body 211, a glue outlet 213 arranged on the bottom of the cylinder body 211, a connecting sleeve 214 sleeved on the glue outlet 213, and a channel 215 inserted on the connecting sleeve 214 and communicating with the glue inlet 16.

[0028] The cylinder body 211 is a cylinder, and the cylinder body 211 is a transparent shell, and the transparent shell is convenient for observing the amount of glue liquid from the outside.

[0029] The opening 212 is arranged at the top. During use, when the sealing cover 22 is opened, glue liquid can be replenished into the cylinder body 211.

[0030] The glue outlet 213 is arranged at the bottom of the cylinder body 211, and the glue liquid will flow to the glue outlet 213 under the action of gravity, which is convenient for the glue liquid to flow from the glue outlet 213 to the glue inlet 16.

[0031] One end of the channel 215 is hermetically connected to the glue inlet 16, and the other end is sleeved on the connecting sleeve 214 and hermetically inserted into the connecting sleeve 214. The channels 215 of the two glue storage cylinders 21 are respectively horizontally arranged and located on the same horizontal plane, so that the cylinder bodies 211 inserted on the channels 215 are respectively located at the same height. The channel 215 communicates with the glue inlet 16, so that the two glue storage cylinders 21 communicate with each other. By respectively blowing air and pumping air at the two air valves 24, the air pressures of the two glue storage cylinders 21 will be changed, so that the glue liquid flows from the high-pressure side to the low-pressure side. When the glue liquid flows, the air charging and discharging states of the two air valves 24 are respectively changed, and the other in the two glue storage cylinders 21 will also change, thereby realizing the back-and-forth flow of the glue liquid in the two glue storage cylinders 21, and further realizing the continuous stirring of the glue liquid to avoid precipitation.

[0032] The sensor 22 is fixedly arranged outside the cylinder body 211 of the glue storage cylinder 21 through a cable tie. The sensor 22 can be a photoelectric sensor. Since the cylinder body 211 of the glue storage cylinder 21 is made of a transparent material, the light emitted by the emitting end of the sensor 22 will pass through the cylinder body 211 and be received by the receiving end on the other side. When the glue blocks the light, the light intensity received by the receiving end will be different from that when the glue does not block the light, so that the glue storage situation can be detected. The sensor 22 located at the upper part of the cylinder body 211 is used to detect the liquid level height to avoid too much glue, while the sensor 22 located at the lower part of the cylinder body 211 is used to avoid running out of glue. The sensor 22 is also connected to a signal processor and a controller, so that it can convert the detection signal into a control signal and control the corresponding module to send a signal through the controller to indicate to the operator that the liquid level is too high or too low.

[0033] The sealing cover 23 is hermetically installed on the top of the glue storage cylinder 21. When it is necessary to add glue, the sealing cover 23 is opened, and glue can be directly injected into the glue storage cylinder 21.

[0034] Each air valve 24 is respectively communicated with an air pump assembly. The air pump assembly is connected through a controller. The controller can be a single-chip microcomputer or a PC, and can control the air pump assembly to cyclically switch between the air-blowing and air-extracting states. After the two air pump assemblies are controlled, they will cyclically switch between the air-extracting and air-blowing states, and the air-extracting and air-blowing states of the two air pump assemblies are staggered respectively, so that the air pressure in the glue storage cylinder 21 changes continuously.

[0035] Compared with the prior art, the glue coating mechanism for preventing material precipitation provided by the present invention sets two mutually communicated glue storage cylinders 21, and an air valve 24 is arranged on the top of each glue storage cylinder 21. Air is blown into or extracted from each glue storage cylinder 21 through the air valve 24, so that a pressure difference is generated between the two glue storage cylinders 21, and then the glue flows in the two glue storage cylinders 21, so as to achieve the purpose of stirring the glue. The air extraction and air discharge states of the air pump assemblies connected to each air valve 24 are opposite, that is, one air pump assembly extracts air while the other blows air, and the air extraction and air discharge states of each air pump assembly cycle alternately, so as to realize the continuous reciprocating flow of the glue and achieve the effect of continuous stirring, thereby avoiding the precipitation of the glue due to long-term stillness.
