[0029] As disclosed in the background art, the colloid in the hose in the prior art is a pre-configured colloid, which is prone to sedimentation and causes excessively high local concentration. During long-term operation, the colloid is prone to affect fluidity and even solidify, which in turn easily leads to glue breakage during dispensing.
[0030] In addition, the existing dispensing equipment has the problem that when the machine is working continuously, the amount of colloid cannot be properly monitored when the colloid is emptied from the machine, resulting in the problem of glue being cut off during dispensing.
[0031] In order to solve the above problems, the embodiments of the present invention provide a glue dispensing device and a glue dispensing equipment. The specific structures of the glue dispensing device and the glue dispensing equipment are introduced in detail below.
[0032] Please refer to Figures 1 to 3 This embodiment provides a dispensing device 100 that can prevent the colloid from solidifying during long-term operation, ensuring the fluidity of the colloid and thus ensuring the dispensing effect. At the same time, it can monitor the amount of glue in real time to avoid the phenomenon of glue breaking during dispensing.
[0033] The dispensing device 100 provided in an embodiment of the present invention includes a main glue hose 110, a glue injection cylinder 130, an oscillator 150 and an auxiliary glue hose 170. The top of the main glue hose 110 is provided with a glue port 111 for inputting a first colloid, and the bottom is provided with a glue nozzle 113. The glue injection cylinder 130 is horizontally placed in the middle of the main glue hose 110 and is connected to the main glue hose 110. The auxiliary glue hose 170 is provided at one end of the glue injection cylinder 130 and is connected to the glue injection cylinder 130 for inputting a second colloid into the glue injection cylinder 130. The oscillator 150 is provided at the other end of the glue injection cylinder 130 for vibrating the glue injection cylinder 130 and the main glue hose 110 to mix the first colloid and the second colloid. The glue nozzle 113 is used to output the mixed colloid, wherein the concentration of the second colloid is lower than that of the first colloid and is used to dilute the first colloid.
[0034] It should be noted that a glue port 111 for inputting the first colloid is provided at the top of the main glue tube 110, and a glue nozzle 113 for outputting the mixed colloid is provided at the bottom. At the same time, the glue injection cylinder 130 is placed horizontally in the middle of the main glue tube 110 and is connected to the main glue tube 110. The auxiliary glue tube 170 is provided at one end of the glue injection cylinder 130 and is connected to the glue injection cylinder 130, and can input the second colloid into the glue injection cylinder 130. The oscillator 150 is provided at the other end of the glue injection cylinder 130 and can vibrate the glue injection cylinder 130 and the main glue tube 110, thereby mixing the first colloid and the second colloid to form a mixed colloid which is then output from the glue nozzle 113. Among them, the concentration of the second colloid is lower than that of the first colloid, thereby diluting the first colloid. By adding the auxiliary glue tube 170 and the oscillator 150, the colloid concentration in the main glue tube 110 can be diluted, thereby preventing the colloid from solidifying during long-term operation, ensuring the fluidity of the colloid, and thus ensuring the dispensing effect.
[0035] It is worth noting that in this embodiment, the main hose 110 is arranged on the external frame in the vertical direction, and the glue injection cylinder 130 is fixedly set in the lower area of the main hose 110 and arranged in the horizontal direction, wherein the glue injection cylinder 130 is connected to the inside of the main hose 110, so that the colloid can flow freely between the main hose 110 and the glue injection cylinder 130 to ensure mixing and transportation.
[0036] In this embodiment, the main hose 110 may contain a first colloid having a certain colloid concentration, while the auxiliary hose 170 may contain a second colloid after diluting the colloid and adding an additive to promote flow or colloid properties. After mixing with the first colloid, the second colloid can dilute the colloid and promote liquid flow.
[0037] It should be noted that in this embodiment, the first colloid and the second colloid can both be made of epoxy resin, high molecular polymer, etc., for implementing the dispensing process. In addition, the oscillator 150 generates high-frequency waves using a high-frequency oscillator 150 to mix the colloids, and the oscillation time is 10s-30s.
[0038] In this embodiment, the glue injection cylinder 130 is also equipped with a control valve 131, located between the main glue hose 110 and the auxiliary glue hose 170, for selectively conducting the glue injection cylinder 130. Specifically, the control valve 131 controls the mixing timing of the first and second colloids. The control valve 131 can also completely block the glue injection cylinder 130, thereby preventing the second colloid from mixing in the initial stage when the first colloid has better flow properties. In the later stage, the control valve 131 can be opened to dilute the colloid.
[0039] Furthermore, a sensor 133 is provided on the control valve 131. The sensor 133 is used to identify the concentration of the colloid in the glue injection barrel 130 and to control the opening or closing of the control valve 131. The sensor can identify the concentration of the mixed colloid in the glue injection barrel 130, so that it can be judged whether the control valve 131 needs to be opened further according to the concentration of the colloid. For example, when the sensor 133 judges that the concentration is too high, it can trigger the control valve 131 to open for mixing. Among them, the sensor 133 can be additionally placed in the top groove of the glue injection barrel 130 and can be inserted into the glue injection barrel 130 to detect the concentration. The control valve 131 can be a solenoid valve and is communicatively connected to the sensor 133. It can realize the opening and closing of the control valve 131 according to the monitoring results of the sensor 133. Its control principle can refer to the relevant description of the prior art.
[0040] In this embodiment, sensor 133 is a density meter or a conductivity detector. Preferably, sensor 133 can be a conductivity detector, which monitors the concentration of the colloid in the injection barrel 130 by conductivity, with higher accuracy. Of course, the type of sensor 133 described here is merely an example and does not constitute a limitation.
[0041] In this embodiment, an air vent 190 is further provided at the top of the main hose 110. This air vent 190 communicates with the hose port 111 and is used to apply pressure to the first colloid. Specifically, air vent 190 is connected to an external air pump, which can inject air into the main hose 110, thereby squeezing the first colloid downward. Compressed air can be injected into air vent 190 to achieve a more effective squeezing effect.
[0042] In this embodiment, a removable rubber sleeve 191 is provided at the top of the main hose 110. One end of the sleeve 191 is positioned over the nozzle 111, and the other end is positioned over the end of the air exhaust pipe 190, thereby connecting the air exhaust pipe 190 to the gate. Specifically, the sleeve 191 is in the form of a hose, which facilitates removal while providing a flexible connection between the air exhaust pipe 190 and the main hose 110.
[0043] Furthermore, a rubber ring buckle 193 is fixedly mounted on the top of the main rubber tube 110. The rubber ring buckle 193 is arranged around the rubber opening 111, and the rubber sleeve 191 is elastically mounted on the outside of the rubber ring buckle 193. Specifically, the rubber ring buckle 193 is annular and is arranged around the top of the main rubber tube 110. The rubber sleeve 191 is elastically mounted on the outside of the rubber ring buckle 193, which can ensure a fixed effect and prevent the rubber sleeve 191 from falling off.
[0044] In this embodiment, a glue injection hole 135 is provided at one end of the glue injection barrel 130 away from the oscillator 150. The glue injection hole 135 is connected to the glue injection barrel 130. The bottom end of the auxiliary glue tube 170 is provided with an assembly joint 171, which is fitted into the glue injection hole 135. Specifically, the size of the glue injection hole 135 is adapted to the size of the assembly joint 171, so that the assembly joint 171 can be interference-fitted into the glue injection hole 135, ensuring effective glue injection.
[0045] In this embodiment, the diameter of the glue nozzle 113 is smaller than the diameter of the main glue tube 110. Specifically, the glue nozzle 113 is tapered and protrudes downward, and can squeeze out a thin and long glue strip, which is convenient for glue dispensing.
[0046] The present invention also provides a dispensing device, including a fixed bracket and a dispensing device 100, wherein the dispensing device 100 includes a main glue hose 110, a glue injection cylinder 130, an oscillator 150, and an auxiliary glue hose 170. The top of the main glue hose 110 is provided with a glue port 111 for inputting a first colloid, and the bottom is provided with a glue nozzle 113. The glue injection cylinder 130 is horizontally placed in the middle of the main glue hose 110 and is connected to the main glue hose 110. The auxiliary glue hose 170 is provided at one end of the glue injection cylinder 130 and is connected to the glue injection cylinder 130 for inputting a second colloid into the glue injection cylinder 130. The oscillator 150 is provided at the other end of the glue injection cylinder 130 for vibrating the glue injection cylinder 130 and the main glue hose 110 to mix the first colloid and the second colloid. The glue nozzle 113 is used to output the mixed colloid, wherein the concentration of the second colloid is lower than that of the first colloid and is used to dilute the first colloid. The main glue hose 110 is movably provided on the fixed bracket.
[0047] In summary, the dispensing device 100 and the dispensing equipment provided in this embodiment are provided with a glue port 111 for inputting a first colloid at the top end of a main glue tube 110, and a glue nozzle 113 for outputting a mixed colloid at the bottom end. A glue injection barrel 130 is placed horizontally in the middle of the main glue tube 110 and communicates with the main glue tube 110. An auxiliary glue tube 170 is provided at one end of the glue injection barrel 130 and communicates with the glue injection barrel 130, capable of inputting a second colloid into the glue injection barrel 130. An oscillator 150 is provided at the other end of the glue injection barrel 130 and is capable of vibrating the glue injection barrel 130 and the main glue tube 110, thereby mixing the first and second colloids to form a mixed colloid that is then outputted from the glue nozzle 113. The concentration of the second colloid is lower than that of the first colloid, thereby diluting the first colloid. Compared with the prior art, the present invention can dilute the colloid concentration in the main hose 110 by adding the auxiliary hose 170 and the oscillator 150, thereby avoiding the colloid from solidifying during long-term operation, ensuring the fluidity of the colloid, and further ensuring the dispensing effect.
