Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a glue supply system and dispensing equipment. Background Technology

[0002] In panel manufacturing, dispensing and sealing technology plays a crucial role. However, in traditional dispensing processes, air bubbles within the adhesive have long plagued manufacturers. To eliminate these bubbles, the industry commonly employs negative pressure to treat the adhesive in the cartridge, but this process is time-consuming and severely impacts production efficiency.

[0003] A more pressing issue is that with a single-tube glue supply, once the glue runs out, the machine must be stopped to replace the new tube. This not only increases downtime but also further reduces dispensing efficiency. Although some dual-tube glue supply systems have emerged on the market, designed to reduce downtime by alternating between the two tubes, these systems are often complex in structure, cumbersome to operate, and expensive, making them difficult to popularize among manufacturers. Therefore, we provide a glue supply system and dispensing equipment to address these problems. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1 The example shown.

[0028] A glue supply system includes a first glue tank 100, a second glue tank 200, a first glue supply assembly 300, a second glue supply assembly 400, a valve group, and a glue spraying component 800.

[0029] In this embodiment, both the first glue bucket 100 and the second glue bucket 200 contain glue. The first glue supply component 300 and the second glue supply component 400 alternately supply glue for dispensing. The valve group is connected to the first glue bucket 100 and the second glue bucket 200 respectively. The first glue supply component 300 is connected to the first glue bucket 100 through the valve group, and the second glue supply component 400 is connected to the first glue bucket 100 and the second glue bucket 200 through the valve group. The glue spraying component 800 is connected to the valve group.

[0030] See Figure 1 As shown, in this embodiment, for example, when glue is supplied from the first glue tank 100, the glue from the first glue tank 100 is transported to the first glue supply assembly 300 through the valve assembly pipeline. The first glue supply assembly 300 supplies glue to the spraying part 800. At this time, under the control of the valve assembly pipeline, the glue from the first glue tank 100 is transported to the second glue supply assembly 400. After the glue in the first glue supply assembly 300 is used up, the glue can be switched to the second glue supply assembly 400 by controlling the pipeline to the spraying part 800 through the valve assembly. In this embodiment, when the first glue tank 100 supplies glue, the second glue tank 200 performs a negative pressure operation to remove air bubbles, in preparation for the glue to be supplied by the second glue tank 200.

[0031] In this embodiment, the adhesive spraying component 800 can be an adhesive spraying valve, or other components capable of applying adhesive to the product; no specific limitation is made here.

[0032] The glue supply system also includes glue discharge tanks 900, which are all connected to the first glue tank 100, the second glue tank 200, the first glue supply component 300, and the second glue supply component 400.

[0033] In this embodiment, during the first use, in order to remove the gas from each pipeline, the glue discharge tank 900 is connected to the first glue tank 100, the second glue tank 200, the first glue supply assembly 300, and the second glue supply assembly 400, so that the gas in each pipeline can be discharged until all pipelines are filled with glue. However, some glue will be discharged during the gas discharge, so the glue discharge tank 900 is used to collect the discharged glue. Furthermore, when not in use for a long time, the waste glue in the pipeline can be discharged and replaced with new glue, and the waste glue is collected by the glue discharge tank 900.

[0034] The first glue tank 100 is provided with a first switching switch 110, which has a first outlet 120 and a second outlet 130. The first outlet 120 is connected to the glue discharge tank 900, and the second outlet 130 is connected to the valve group. The first glue tank 100 is also provided with a first connector 140, which is used to apply positive or negative pressure to the first glue tank 100.

[0035] The second glue tank 200 is provided with a second switching switch 210, which has a third outlet 220 and a fourth outlet 230. The third outlet 220 is connected to the glue discharge tank 900, and the fourth outlet 230 is connected to the valve group. The second glue tank 200 is also provided with a second connector 240.

[0036] See Figure 1 As shown, in this embodiment, during normal glue supply, the second outlet 130 or the fourth outlet 230 is connected to the valve assembly, and the first connector 140 or the second connector 240 is pressurized, thereby facilitating the delivery of glue to the first glue supply assembly 300 or the second glue supply assembly 400. For example, when the first glue tank 100 is supplying glue, the first connector 140 is pressurized, and the second outlet 130 is opened and the first outlet 120 is closed by the first switching switch 110. At this time, the glue inside the first glue tank 100 will enter through the pipeline formed by the second outlet 130 and the valve assembly. When the glue is supplied to the first glue supply assembly 300 or the second glue supply assembly 400, it should be noted that the fourth outlet 230 is closed by the second switching switch 210 to prevent the glue from the first glue tank 100 from entering the second glue tank 200 through the fourth outlet 230. Negative pressure is applied to the second connector 240. Under the action of negative pressure, the air bubbles in the glue in the second glue tank 200 will be gradually discharged, realizing negative pressure degassing and ensuring production quality. Furthermore, in practice, the degassing time is at least half an hour. After the degassing is completed, positive pressure is applied to the second connector 240.

[0037] In this embodiment, upon first use or when changing to a different type of adhesive, the first outlet 120 is opened via the first switch 110, and positive pressure is applied to the first connector 140, causing the adhesive to flow from the first outlet 120 into the discharge tank 900, thereby expelling the gas or waste adhesive from the first adhesive tank 100. Similarly, the third outlet 220 is opened and the fourth outlet 230 is closed via the second switch 210, and positive pressure is applied to the second connector 240, causing the adhesive in the second adhesive tank 200 to enter the discharge tank 900 through the pipe connected to the third outlet 220, thereby expelling the gas or waste adhesive from the second switch 210 and ensuring the consistency of the adhesive.

[0038] The first glue supply assembly 300 includes a first glue cylinder 310, on which a third switching switch 320 is provided. The third switching switch 320 has a fifth outlet 330 and a sixth outlet 340. The fifth outlet 330 is connected to the valve group, and the sixth outlet 340 is connected to the glue discharge tank 900. The first glue supply assembly 300 also includes a first driving cylinder 350, which is operatively connected to the first glue cylinder 310. The first driving cylinder 350 is used to drive the first glue cylinder 310 to draw or discharge glue.

[0039] The second glue supply assembly 400 includes a second glue cylinder 410, on which a fourth switch 420 is installed. The fourth switch 420 has a seventh opening 430 and an eighth outlet 440. The seventh opening 430 is connected to the valve group, and the eighth outlet 440 is connected to the glue discharge tank 900. The second glue supply assembly 400 also includes a second drive cylinder 450, which is operatively connected to the second glue cylinder 410. The second drive cylinder 450 is used to drive the second glue cylinder 410 to draw or discharge glue.

[0040] Please continue reading. Figure 1As shown, in this embodiment, both the first glue cylinder 310 and the second glue cylinder 410 serve to store glue, and then deliver the stored glue to the spraying component 800, allowing the spraying component 800 to apply the glue to the product. Specifically, when the first glue supply component 300 needs to supply glue to the spraying component 800, or when glue is supplied by the first glue tank 100, under the control of the valve group, the first outlet 120 is connected to the fifth outlet 330, and the first drive cylinder 350 contracts, increasing the internal space of the first glue cylinder 310. Under the negative pressure inside the first glue cylinder 310 and the positive pressure of the first glue tank 100, the glue in the first glue tank 100 enters the first glue cylinder 310. Then, again under the control of the valve group, the fifth outlet 330 is connected to the spraying component 800, and the first drive cylinder 350 extends, delivering the glue inside the first glue cylinder 310 to the spraying component 800, thus completing the glue delivery process. During the process of delivering glue to the first glue cylinder 310, the second outlet 130 is connected to the seventh opening 430 under the control of the valve group control pipeline. The second drive cylinder 450 contracts, allowing the glue in the first glue tank 100 to enter the second glue cylinder 410, thus completing the storage of glue in the second glue cylinder 410. When the glue in the first glue cylinder 310 is used up, the valve group connects the seventh opening 430 to the glue spraying part 800. The second drive cylinder 450 extends, allowing the glue in the second glue cylinder 410 to be delivered to the glue spraying part 800. During the process of the second glue cylinder 410 delivering glue to the glue spraying part 800, the valve group connects the second outlet 130 and the fifth outlet 330 again. The first drive cylinder 350 contracts, allowing the glue from the first glue tank 100 to re-enter the first glue cylinder 310 for storage. The above operation is repeated to achieve uninterrupted supply of glue to the glue spraying part 800.

[0041] It should be noted that both the first glue cylinder 310 and the second glue cylinder 410 have a cylinder cavity for storing glue and a piston. The piston keeps the inside of the cylinder cavity under positive or negative pressure. When the cylinder cavity is under negative pressure, it is in the process of gradually storing glue. When the cylinder cavity is under positive pressure, it is in the process of delivering glue to the spraying part 800. Furthermore, the piston in the first glue cylinder 310 is driven by the first drive cylinder 350, and the piston in the second glue cylinder 410 is driven by the second drive cylinder 450. Furthermore, when the first drive cylinder 350 and the second drive cylinder 450 are in the extended state, the inside of the cylinder cavity is under positive pressure. When the first drive cylinder 350 and the second drive cylinder 450 are in the contracted state, the inside of the cylinder cavity is under negative pressure.

[0042] The valve assembly includes a first valve body 500, which has a first connection port 510, a second connection port 520, and a third connection port 530. The first connection port 510 is connected to the first glue tank 100 and the second glue tank 200, and the second connection port 520 is connected to the second glue supply assembly 400.

[0043] The valve assembly includes a second valve body 600, which has a fourth connection port 610, a fifth connection port 620, and a sixth connection port 630. The fourth connection port 610 is connected to the first glue supply assembly 300, and the fifth connection port 620 is connected to the first glue tank 100 and the second glue tank 200.

[0044] The valve assembly includes a third valve body 700, which has a seventh connection port 710 and an eighth connection port 720. The seventh connection port 710 is connected to the sixth connection port 630, and the eighth connection port 720 is connected to the adhesive spraying component 800. The third valve body 700 also has a ninth connection port 730 and an adhesive discharge port 740. The ninth connection port 730 is connected to the third connection port 730, and the adhesive discharge port 740 is connected to the adhesive discharge tank 900.

[0045] Please see Figure 1 As shown, taking the first glue tank 100 as an example, the first switching switch 110 controls the second outlet 130 to connect with the inside of the first glue tank 100, the first connector 140 is connected to positive pressure, the third switching switch 320 controls the fifth outlet 330 to connect with the inside of the first glue cylinder 310, the fourth switching switch 420 controls the seventh opening 430 to connect with the inside of the second glue cylinder 410, and controls the fourth connection port 610 and the fifth connection port 620 of the second valve body 600 to be in a connected state. At this time, the first connection port 510 and the second connection port 520 are in a disconnected state.

[0046] The first drive cylinder 350 contracts, causing the piston inside the first glue cylinder 310 to move. Glue from the first glue container 100 enters the first glue cylinder 310 through the passage formed by the second outlet 130, the fifth connection port 620, the fourth connection port 610, and the fifth outlet 330, until the first glue cylinder 310 is full of glue. Next, the fourth connection port 610 of the second valve body 600 is connected to the sixth connection port 630, and the seventh connection port 710 of the third valve body 700 is connected to the eighth connection port 720. The first connection port 510 of the first valve body 500 is connected to the second connection port 520. The first drive cylinder 350 extends, causing the piston inside the first glue cylinder 310 to move and compress the glue. At this time, the glue inside the first glue cylinder 310... The adhesive is transported to the spraying component 800 through the passage formed by the fifth outlet 330, the fourth connection port 610, the sixth connection port 630, the seventh connection port 710, and the eighth connection port 720, thereby providing adhesive to the spraying component 800. While the first glue cylinder 310 continuously supplies adhesive to the spraying component 800, the second drive cylinder 450 contracts, causing the piston in the second glue cylinder 410 to move. At this time, the inside of the second glue cylinder 410 is under negative pressure. The adhesive from the first glue tank 100 enters the second glue cylinder 410 through the passage formed by the second outlet 130, the first connection port 510, the second connection port 520, and the seventh opening 430, until the second glue cylinder 410 is full of adhesive, thus completing the storage of adhesive in the second glue cylinder 410.

[0047] After the glue in the first glue cylinder 310 is used up, the second connection port 520 and the third connection port 530 of the first valve body 500 are connected, and the ninth connection port 730 and the eighth connection port 720 of the third valve body 700 are connected. The fourth connection port 610 and the fifth connection port 620 are also connected, so that the first glue tank 100 can store glue in the first glue cylinder 310 again through the passage formed by the second outlet 130, the fifth connection port 620, the fourth connection port 610 and the fifth outlet 330. Next, the second drive cylinder 450 extends and drives the piston in the second glue cylinder 410 to compress the glue, so that the glue in the second glue cylinder 410 is supplied to the glue spraying part 800 through the passage formed by the seventh opening 430, the second connection port 520, the third connection port 530, the ninth connection port 730 and the eighth connection port 720. Then the above cycle is repeated so that glue can be supplied to the glue spraying part 800 without interruption.

[0048] When the glue in the first glue tank 100 is used up, the first switch 110 closes the connection between the second outlet 130 and the inside of the first glue tank 100. Then, the second switch 210 controls the fourth outlet 230 to connect with the inside of the second glue tank 200, so that the second glue tank 200 provides glue to the first glue cylinder 310 and the second glue cylinder 410. The specific operation is the same as that of the first glue tank 100, and will not be described in detail here.

[0049] In this implementation, all the aforementioned switch valves and components can be automatically controlled, specifically through a host computer, a computer, an industrial control computer, etc.

[0050] In this embodiment, both the first glue bucket 100 and the second glue bucket 200 are equipped with a weighing sensor (not shown in the figure) at their bottom. The weighing sensor detects the weight of the glue in the first glue bucket 100 and the second glue bucket 200, thereby automatically switching to the other glue bucket for glue supply. In this embodiment, an alarm component can also be set, such as prompting the replacement of a new glue bucket containing glue through a speaker.

[0051] Please continue reading. Figure 1 As shown, when the gas in the pipeline is first used or when waste glue needs to be discharged, the first switch 110 controls the first outlet 120 to open and the first glue tank 100 to open. The first connector 140 is pressurized, and the glue will be discharged through the passage connecting the first outlet 120 and the glue discharge tank 900, thereby discharging the gas or waste glue in the pipeline. Similarly, the second switch 210 controls the third outlet 220 to connect and the second glue tank 200 to open. The second connector 240 is pressurized, and the glue will be discharged into the glue discharge tank 900 through the passage connecting the third outlet 220 and the glue discharge tank 900, thereby discharging the gas and waste glue in the pipeline.

[0052] Furthermore, taking the glue supply from the first glue tank 100 as an example, when it is necessary to vent air or waste glue from the pipeline where the first glue cylinder 310 is located, the fourth connection port 610 of the second valve body 600 is connected to the fifth connection port 620, and the fifth outlet 330 of the third switch 320 is connected to the sixth outlet 340. Glue from the first glue tank 100 will be discharged into the glue discharge tank 900 through the pipeline formed by the second outlet 130, the fifth connection port 620, the fourth connection port 610, the fifth outlet 330, the sixth outlet 340, and the glue discharge tank 900. In this way, air or waste glue in the pipeline is discharged. Specifically, when air or waste glue is discharged from the pipeline where the second glue cylinder 410 is located, the first connection port 510 is connected to the second connection port 520, and the seventh opening 430 of the fourth switching switch 420 is connected to the eighth outlet 440. At this time, the glue from the first glue tank 100 will enter the glue discharge tank 900 through the passage formed by the first connection port 510, the second connection port 520, the seventh opening 430, the eighth outlet 440 and the glue discharge tank 900, thereby discharging the gas or waste glue in the passage.

[0053] When it is necessary to discharge gas or waste glue from the valve assembly, taking the first glue tank 100 as an example again, the fifth connection port 620 of the second valve body 600 is connected to the sixth connection port 630, and the seventh connection port 710 of the third valve body 700 is connected to the glue discharge port 740. The glue from the first glue tank 100 enters the glue discharge tank 900 through the passage formed by the second outlet 130, the fifth connection port 620, the seventh connection port 710, the glue discharge port 740, and the glue discharge tank 900, thereby being discharged from the pipe. Next, the first connection port 510 of the first valve body 500 is connected to the third connection port 530, and the ninth connection port 730 of the third valve body 700 is connected to the glue discharge port 740. The glue from the first glue tank 100 enters the glue discharge tank 900 through the pipeline formed by the second outlet 130, the first connection port 510, the third connection port 530, the ninth connection port 730, the glue discharge port 740, and the glue discharge tank 900, thereby discharging the gas and waste glue in the pipeline.

[0054] It should be noted that all the components mentioned above are connected by connecting pipes.

[0055] This application also provides a dispensing device, which includes any of the above-described adhesive supply systems.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
