DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 2 As shown, a preferred embodiment of the utility model proposes a glue erasing device for automatically adding cleaning agent, and the glue erasing device mainly includes: a device body 2, a cleaning tank 5, a cleaning agent container 7, a liquid control valve 8 and other components, wherein the device body 2, the cleaning agent container 7, and the liquid control valve 8 are all mounted and fixed on the substrate 1, and an electrical component is arranged in the device body 2 for controlling the operation of the entire device.

[0026] The device body 2 is composed of two parts, a vertical plate 22 and a shield 21. A sealed space is formed between the shield 21 and the vertical plate 22 for accommodating electrical components. A driving shaft 3, a driven shaft 4 and at least two auxiliary shafts 9 are arranged on the outside of the vertical plate 22. The driving shaft 3 is rotatably connected to the vertical plate 22 and is driven and connected to the winding motor 16 on the inside of the vertical plate 22. The driven shaft 4 is rotatably connected to the vertical plate 22. The driving shaft 3 is used to fix the receiving roll 10, and the driven shaft 4 is used to fix the unwinding roll 11. The receiving roll 10 and the unwinding roll 11 are both used to wind the dust-free cloth for cleaning. The driving shaft 3 is driven to rotate by the winding motor 16, and the receiving roll 10 will rewind the dust-free cloth after wiping the nozzle. At the same time, the driven shaft 4 will passively rotate, and the unwinding roll 11 will release the clean dust-free cloth.

[0027] like Figure 1 As shown, the cleaning tank 5 is located between the driving shaft 3 and the driven shaft 4. The top of the cleaning tank 5 accommodates a cleaning sponge 6. Inside the cleaning tank 5, a liquid storage tank is formed at the bottom of the cleaning sponge 6. A detergent nozzle is provided in the liquid storage tank to add detergent to the sponge. The detergent that cannot be absorbed by the sponge flows into the liquid storage tank at the bottom for storage.

[0028] At least one auxiliary shaft 9 is arranged on both sides of the cleaning tank 5, and the auxiliary shaft 9 is rotatably connected to the vertical plate 22. After the clean dust-free cloth is released from the unwinding roll 11, it will pass through the auxiliary shaft 9, the sponge and the auxiliary shaft 9 in sequence, and finally the dust-free cloth after wiping the nozzle will be rolled up onto the receiving roll 10.

[0029] The auxiliary shafts 9 located on both sides of the cleaning tank 5 guide and support the dust-free cloth belt and press the two ends of the dust-free cloth tightly, so that the dust-free cloth is in a tight state. The sponge absorbs the cleaning agent in the cleaning tank 5, and the dust-free cloth is in close contact with the upper surface of the sponge, and the sponge guides the cleaning agent to the tightly stretched dust-free cloth above.

[0030] like Figure 1 As shown, the detergent container 7 has an air inlet and a liquid outlet, both of which are located at the top of the detergent container 7, wherein the air inlet is connected to the gas pipeline 17, and the other end of the gas pipeline 17 is connected to an external pumping gas source; the liquid outlet is connected to the liquid outlet pipeline 18, and the other end of the liquid outlet pipeline 18 is connected to the inlet of the liquid control valve 8, and the outlet of the liquid control valve 8 is connected to the detergent nozzle in the cleaning tank 5 through the liquid supply pipeline 19, and the cleaning liquid flows into the cleaning tank 5 through the liquid supply pipeline 19. The liquid control valve 8 adopts a solenoid valve, which can be opened and closed by the system to control the delivery of the detergent.

[0031] The gas pipeline 17 will extend to a position near the top of the detergent container 7, and the liquid outlet pipeline 18 will extend to a position near the bottom of the detergent container 7. The gas pipeline 17 will pressurize the space above the detergent in the detergent container 7 through a low-pressure gas source, so that the detergent in the detergent container 7 will flow out from the liquid outlet pipeline 18 due to the increase in pressure inside the container and be pumped into the liquid control valve 8. The liquid control valve 8 will control the frequency and amount of the detergent delivered to the cleaning tank 5 each time, and the liquid control valve 8 is centrally controlled by the equipment system.

[0032] like Figure 2 As shown, a glue collection cup 12 is also provided on the inner side of the device body 2, and the top of the glue collection cup 12 has an opening, which passes through the top of the shield 21. Before wiping the glue spray valve, some glue needs to be sprayed out first, and it is specified to be sprayed in the glue collection cup 12 for easy cleaning and replacement.

[0033] An electric control line connector 13 is also provided on one side of the shield 21 . The electric control line connector 13 is electrically connected to the electrical components in the device body and is used to connect to the control mechanism of the system.

[0034] refer to Figure 3In order to control the release length of the dust-free cloth after wiping the glue spray valve each time, a cross baffle 14 is provided at the inner end of one of the auxiliary shafts 9 (i.e., the end close to the inner side of the device body 2), and a photoelectric sensor 15 is also provided on the vertical plate 22. When the cross baffle 14 rotates with the auxiliary shaft 9, the cross baffle 14 will intermittently block the laser emitted by the photoelectric sensor 15. In this way, the photoelectric sensor 15 can detect the number of rotations of the cross baffle 14, that is, the number of rotations of the auxiliary shaft 9, and indirectly measure the release length of the dust-free cloth, so that the system will control the number of rotations of the winding motor 16.

[0035] The device has two workflows:

[0036] When wiping glue: first, the glue spray valve will move to the glue collection cup 12 to spray out the excess glue, and then the glue spray valve will move above the cleaning sponge 6 and contact with the dust-free cloth. Then the winding motor 16 controls the driving shaft 3 to rotate and winds up the dust-free cloth. The dust-free cloth soaked in the cleaning agent will rub away the residual glue on the nozzle of the glue spray valve, and the nozzle of the glue spray valve is cleaned.

[0037] When adding detergent: one end of the detergent container 7 is connected to the low-pressure air source, and the other end is connected to the liquid control valve 8. When it is necessary to automatically add detergent, the system controls the liquid control valve 8 to open, and the detergent is sprayed into the cleaning tank 5 through the pipeline, and the detergent is added to the cleaning tank 5. After the specified time, the system controls the liquid control valve 8 to close, and the detergent in the cleaning tank 5 is replenished.

[0038] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
