[0026] The following description, in conjunction with the accompanying drawings, describes an adhesive supply device capable of removing air bubbles from adhesive according to an embodiment of the present invention.

[0027] Reference Figure 1 The present invention aims to provide an embodiment of a glue supply device that can remove air bubbles from glue.

[0028] An embodiment of the present invention provides a glue supply device for removing air bubbles from glue, comprising a glue extraction mechanism, which includes a glue extraction tube 100, a glue extraction pump 110, and a solenoid valve 120. The glue extraction tube 100 is connected to a glue tank 240. The glue extraction pump 110 and the glue extraction tube 100 cooperate to extract glue from the glue tank 240 to the glue application assembly 130. The solenoid valve 120 is connected to the glue outlet of the glue extraction pump 110 to control the opening and closing of the glue outlet of the glue extraction pump 110.

[0029] It is understood that this utility model, by setting up a glue extraction tube 100, a glue extraction pump 110, and a solenoid valve 120, allows the glue extraction tube 100 to be inserted into the glue tank 240. The glue extraction pump 110 and the glue extraction tube 100 work together to extract the glue from the glue tank 240. Furthermore, the solenoid valve 120 is in the open state, enabling the glue to be delivered to the glue application assembly 130. If air bubbles are detected in the glue, the solenoid valve 120 is in the closed state, preventing the glue containing air bubbles from being delivered to the glue application assembly 130. In addition, when removing glue, the glue extraction pump 110 can also extract the glue containing air bubbles.

[0030] An embodiment of the present invention provides a glue supply device capable of removing glue air bubbles, which further includes a bubble removal mechanism. The bubble removal mechanism includes a bubble sensor 140, a glue discharge tube 150, and a switch control component. The bubble sensor 140 is connected to the glue extraction tube 100 and is used to detect glue air bubbles in the glue extraction tube 100. The glue discharge tube 150 is connected to the glue extraction tube 100, and the switch control component is connected to the glue discharge tube 150 to control the glue discharge from the glue discharge tube 150.

[0031] It is understood that, by setting up a bubble sensor 140, a glue discharge pipe 150, and a switch control component, this utility model allows the glue inside the glue extraction pipe 100 to pass through the bubble sensor 140 when the glue supply device is supplying glue. The bubble sensor 140 can detect bubbles in the glue and feed back relevant electrical signals, causing the glue extraction pump 110 to stop extracting glue. Furthermore, the solenoid valve 120 is in the closed state to ensure that the glue is not delivered to the glue application assembly 130 when removing bubbles. Then, the switch control component is opened, putting the glue discharge pipe 150 in the conductive state, and the glue extraction pump 110 is turned on again. The glue extraction pump 110 extracts the glue containing bubbles, and the glue containing bubbles is discharged through the glue discharge pipe 150. Thus, the function of monitoring bubbles in the glue and removing bubbles can be achieved during glue supply, ensuring good glue application quality and product quality, and improving production efficiency.

[0032] It should be noted that the bubble sensor 140 and the glue pump 110 are connected through a control system. After the bubble sensor 140 transmits relevant electrical signals to the control system, the control system can control the working state of the glue pump 110.

[0033] Preferably, the switch control component is an overflow valve 160. It can be understood that the overflow valve 160 mainly has the following functions: on the one hand, when removing glue containing air bubbles, the valve of the overflow valve 160 is turned on, so that the glue discharge pipe 150 is in a conductive state, and the glue containing air bubbles can be discharged; on the other hand, when the pressure of the pipeline or pump exceeds the set value of the overflow valve 160, the overflow valve 160 automatically opens, and the glue is discharged through the glue discharge pipe 150, so as to avoid pipeline rupture, damage to the glue pump 110 or seal failure due to excessive pressure.

[0034] In some embodiments of this utility model, reference is made to Figure 1 The dispensing tube 150 is located at the end of the dispensing tube 100 near the bubble sensor 140. Therefore, the distance between the dispensing tube 150 inlet and the bubble sensor 140 is very short. When removing bubbles, the amount of glue with bubbles passing through the pipe between the dispensing tube 150 inlet and the bubble sensor 140 is reduced, thus preventing the glue with bubbles from being delivered to the glue application assembly 130.

[0035] In some embodiments of this utility model, the glue discharge tube 150 is a transparent tube. It can be understood that when removing glue containing air bubbles, the operator can observe the air bubble situation of the glue through the transparent tube. If air bubbles are observed in the glue in the transparent tube, the glue discharge continues. If no air bubbles are observed in the glue in the transparent tube, it indicates that the air bubble removal is complete, and the glue discharge stops.

[0036] In some embodiments of this utility model, the glue discharge tube 150 is arranged to extend vertically or obliquely. It can be understood that when the glue discharge tube 150 discharges glue, the glue can slide down from top to bottom, making it easier for the glue to be discharged from the glue discharge tube 150.

[0037] In some embodiments of this utility model, reference is made to Figure 1 The glue pump 110 is electrically connected to a manual button 170, which is used to manually turn the glue pump 110 on or off.

[0038] Specifically, the glue pump 110 and the manual button 170 are indirectly connected through a control system. When removing air bubbles, the operator presses the manual button 170 to start the glue pump 110. The glue pump 110 draws glue through the glue extraction tube 100, and the glue containing air bubbles is discharged through the glue discharge tube 150. After the air bubbles are removed, the operator presses the manual button 170 again to stop the glue pump 110 from working. Then, the switch control prevents the glue from being discharged from the glue discharge tube 150.

[0039] In some embodiments of this utility model, a glue receiving component 180 is provided at the end of the glue discharge pipe 150 away from the glue extraction pipe 100. The glue receiving component 180 is used to receive the glue discharged from the glue discharge pipe 150, thereby facilitating the recycling or disposal of the glue discharged from the glue discharge pipe 150, and also avoiding the trouble of cleaning up the glue caused by the discharged glue falling on the equipment.

[0040] In some embodiments of this utility model, reference is made to Figure 2 The glue receiving assembly 180 includes a glue cup 190 and a cover 200. The glue cup 190 is used to collect glue. The cover 200 is connected to a bracket 210 and is disposed in a through hole for accommodating the glue discharge tube 150. The cover 200 is detachably connected to the opening of the glue cup 190.

[0041] Understandably, by setting up the glue cup 190 and the cover 200, the glue cup 190 can collect the glue discharged from the glue discharge tube 150, while the cover 200 seals the opening of the glue cup 190, preventing the volatile gases generated by the glue in the glue cup 190 from escaping from the glue cup 190.

[0042] At the same time, when the glue in the glue cup 190 reaches two-thirds of its volume, the glue cup 190 can be removed from the cover 200, and the glue in the glue cup 190 can be processed.

[0043] In some embodiments of this utility model, reference is made to Figure 2 The cover 200 is provided with an air hole 220, which is used to balance the internal and external air pressure of the glue cup 190. Thus, when the glue discharge tube 150 discharges glue, the air pressure inside the glue cup 190 is consistent with the outside, ensuring that the glue discharge tube 150 discharges glue smoothly.

[0044] In some embodiments of this utility model, the cover 200 is provided with a sealing body 230 that matches the vent 220. Therefore, after the glue is discharged, the sealing body 230 can be used to block the vent 220, preventing the volatile gas generated by the glue in the glue cup 190 from leaving the glue cup 190.

[0045] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
