Wherein, spout gluey equipment and can independently carry out and spout gluey operation, remaining equipment is used for spouting gluey equipment and washs.
The glue spraying equipment comprises a glue barrel 11, a pressure pump 14, a pressure reducing valve 15, a glue gun 17 and an air compression device 18, wherein the glue barrel 11, the pressure pump 14, the pressure reducing valve 15, the glue gun 17 and the air compression device 18 are sequentially connected. When the glue spraying operation is performed, the flow rate and the pressure of the glue entering the glue gun 17 from the glue barrel 11 are controlled by adjusting the pressure pump 14 and the pressure reducing valve 15, and then the compressed air entering the glue gun 17 is controlled by the air compression device 18 so as to spray the glue to the target position through the glue gun 17.
The main pipeline bidirectional switching valve 21 is arranged between the glue barrel 11 and the pressure pump 14 of the glue spraying equipment and is connected with the cleaning liquid supply device. Two inlets of the main pipeline bidirectional switching valve 21 are respectively connected with the rubber barrel 11 and the cleaning liquid supply device in a one-to-one correspondence manner, and an outlet of the main pipeline bidirectional switching valve 21 is connected with the pressure pump 14. Therefore, when spraying is needed, the main pipeline bidirectional switching valve 21 is adjusted to communicate the glue barrel 11 with the pressure pump 14, so that glue flows from the glue barrel 11 to the pressure pump 14 to perform glue spraying operation. When the glue spraying equipment needs to be cleaned, the cleaning liquid supply device is communicated with the pressure pump 14 by adjusting the main pipeline bidirectional switching valve 21, so that on one hand, glue is prevented from further entering a pipeline of the glue spraying equipment, and on the other hand, the cleaning liquid provided by the cleaning liquid supply device can conveniently enter the pipeline of the glue spraying equipment for cleaning.
The first glue-discharging two-way switching valve 25 is arranged between the pressure reducing valve 15 and the glue gun 17 of the glue spraying equipment and is connected with the first main pipe cleaning liquid outlet 24. Wherein, the inlet of the first glue discharging two-way switching valve 25 is connected with the pressure reducing valve 15, and two outlets of the first glue discharging two-way switching valve 25 are respectively connected with the glue gun 17 and the first main pipeline cleaning liquid outlet 24 in a one-to-one correspondence manner.
Therefore, when spraying is needed, the main pipeline two-way switching valve 21 is adjusted to communicate the glue barrel 11 with the pressure pump 14, and the first glue discharging two-way switching valve 25 is adjusted to communicate the pressure reducing valve 15 with the glue gun 17, so that glue flows from the glue barrel 11 to the glue gun 17 to perform glue spraying operation. When the pipelines of the glue spraying equipment except the glue gun 17 need to be cleaned, the main pipeline bidirectional switching valve 21 is adjusted to communicate the cleaning liquid supply device with the pressure pump 14, so that the cleaning liquid provided by the cleaning liquid supply device enters the pipeline of the glue spraying equipment for cleaning, meanwhile, the first glue discharging bidirectional switching valve 25 is adjusted to communicate the pressure reducing valve 15 with the first main pipeline cleaning liquid outlet 24, and the cleaning liquid cleaned through the pipeline is discharged from the first main pipeline cleaning liquid outlet 24.

Optionally, in another embodiment of the present invention, the glue spraying apparatus further includes a filter 12 disposed between the main pipeline bidirectional switching valve 21 and the pressure pump 14, and an outlet of the main pipeline bidirectional switching valve 21 is connected to the filter 12. Because there may be impurity in the glue, therefore, when needs carry out the spraying, filter 12 filters the glue that flows out in gluing the bucket 11, reduces the probability that spouts gluey equipment jam.
In addition, the glue spraying equipment further comprises a flow meter 13 arranged between the filter 12 and the pressure pump 14, the flow meter 13 is used for obtaining the glue flow flowing through the pipeline, the glue supply speed can be controlled during glue spraying operation through the glue flow, different threshold values can be set on the other hand, and whether the current pipeline is blocked and whether the blockage is serious can be judged.
Optionally, in another embodiment of the present invention, since the pipeline between the glue barrel 11 and the glue gun 17 of the glue spraying device is long, and a flow meter 13 or the like is also provided, if there is only one cleaning line, the cleaning efficiency is low. Therefore, the automatic cleaning device further comprises a second glue discharging two-way switching valve 22 and a second main pipeline cleaning liquid outlet 23, wherein the second glue discharging two-way switching valve 22 is arranged between the flowmeter 13 and the pressure pump 14 and is used for controlling a pipeline between the glue barrel 11 and the pressure pump 14 of the glue spraying equipment. An inlet of the second glue discharging two-way switching valve 22 is connected with the flowmeter 13, and two outlets of the second glue discharging two-way switching valve 22 are respectively connected with the pressure pump 14 and the second main pipeline cleaning liquid outlet 23 in a one-to-one correspondence manner.

When the pipelines of the glue spraying equipment except the glue gun 17 need to be cleaned, different pipelines are cleaned according to the flow rate of glue flowing through the pipelines obtained by the flowmeter 13.
When the glue flow is smaller than the first preset threshold, it is indicated that the glue in the current pipeline is difficult to circulate and is seriously blocked, therefore, the main pipeline bidirectional switching valve 21 is adjusted to communicate the cleaning liquid supply device with the flowmeter 13, and the second glue discharging bidirectional switching valve 22 is adjusted to communicate the flowmeter 13 with the second main pipeline cleaning liquid discharge port 23, so that the cleaning liquid provided by the cleaning liquid supply device cleans the local pipeline of the glue spraying equipment.
Then, when the glue flow is larger than or equal to the first preset threshold and smaller than the second preset threshold, it is indicated that the glue blockage situation in the current pipeline is slight, therefore, the main pipeline bidirectional switching valve 21 is adjusted to communicate the cleaning liquid supply device with the flowmeter 13, the second glue discharging bidirectional switching valve 22 is adjusted to communicate the flowmeter 13 with the pressure reducing valve 15, the first glue discharging bidirectional switching valve 25 is adjusted to communicate the pressure reducing valve 15 with the first main pipeline cleaning liquid discharge port 24, the cleaning liquid which has cleaned the pipeline is discharged from the first main pipeline cleaning liquid discharge port 24, and the cleaning liquid provided by the cleaning liquid supply device is used for cleaning all pipelines between the glue barrel 11 and the glue gun 17 in the glue spraying device.
According to the invention, different pipelines are cleaned by controlling the flow of glue flowing through the pipelines according to the flow obtained by the flowmeter 13, the cleaning efficiency is higher, and meanwhile, the phenomenon that glue at the tail end is accumulated to block the pipelines due to long-line cleaning is avoided. In addition, the fault point can be quickly positioned by controlling the switching of different bidirectional switching valves during fault, and the targeting property is higher.
Alternatively, in a further embodiment of the invention, the glue gun 17 comprises an atomizing cap connected to the pressure reducing valve 15, the air compressing device 18, and a nozzle 16 connected to the atomizing cap, the atomizing cap atomizes the glue by compressed air and then sprays it through the nozzle 16 to the target location.
