Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically a drip-type adhesive application device. Background Technology

[0002] Dispensing machines precisely apply adhesive through dispensing heads to achieve bonding, sealing, or encapsulation processes. During dispensing, residual adhesive easily adheres to the surface of the dispensing head. If not cleaned promptly, this can lead to head clogging, inaccurate dispensing amounts, or contamination of subsequent processed parts, severely impacting dispensing quality and equipment stability. To address this issue, after completing a single dispensing operation, the dispensing head moves above a dissolving agent tank and is submerged in the agent through an opening at the top of the tank. The dissolving agent removes the adhesive adhering to the surface, ensuring the dispensing head can be reused.

[0003] However, the undissolving agent in the undissolving tank is usually supplied by a pump to maintain the liquid level and ensure that the dispensing head is fully submerged. But because the dispensing head is repeatedly immersed in the undissolving agent, the liquid level fluctuates constantly. To maintain a stable level, the pump needs to be frequently started and stopped to replenish the undissolving agent. This frequent start-stop operation increases the mechanical wear and electrical load on the pump, leading to frequent pump failures and thus affecting dispensing efficiency.

[0004] Therefore, there is an urgent need for a dispensing head cleaning system that can stably maintain the level of the desiccant and overcome the tendency of pumps to fail, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a drip-type adhesive application device.

[0006] This utility model provides a drip-type adhesive removal device, including an adhesive removal box filled with adhesive removal agent, an insertion interface at the upper end of the adhesive removal box for inserting an adhesive head, and a glue bucket filled with adhesive removal agent. The glue bucket is positioned above the glue release box; The outlet of the glue bucket is connected to the inlet of the glue dissolving box via a glue delivery pipe; An on / off valve is installed on the rubber delivery hose; The adhesive release agent in the glue bucket flows into the adhesive release box under the action of gravity.

[0007] Furthermore, a sponge plate is provided at the insertion interface, which floats on the liquid surface of the adhesive remover.

[0008] Furthermore, the liquid level inside the degumming tank is configured such that the height of the upper surface of the sponge plate is higher than the height of the lower surface of the top plate of the degumming tank.

[0009] Furthermore, the sponge board and the inner wall of the insertion interface are fitted with a clearance.

[0010] Furthermore, the degumming tank is equipped with high-level and low-level sensors arranged vertically. The high liquid level sensor controls the on / off valve to close; The low liquid level sensor controls the on / off valve to open.

[0011] Furthermore, a high liquid level detection tube and a low liquid level detection tube are installed on the degumming tank; The high liquid level sensor is installed on the high liquid level detection tube; The low liquid level sensor is installed on the low liquid level detection tube.

[0012] Furthermore, the high-level detection tube and the low-level detection tube are U-shaped, with one end connected to the bottom of the degumming tank and the other end higher than the liquid level in the degumming tank.

[0013] Furthermore, the on / off valve is a solenoid valve.

[0014] The beneficial effects of this utility model are: 1. By placing the glue container filled with dissolving agent above the dissolving tank, the dissolving agent is continuously and naturally replenished into the tank via a glue delivery pipe, utilizing its own gravity. This liquid level balancing mechanism, based on the principle of communicating vessels, automatically compensates for liquid level fluctuations caused by the dispensing head's immersion and solvent evaporation, thereby stably maintaining the liquid level at a preset height. This ensures that the dispensing head is fully submerged each time, achieving a reliable and consistent cleaning effect.

[0015] 2. This invention replaces the traditional method of relying on frequent pump start-stop cycles to replenish the dissolving agent. Through gravity-fed supply and coordinated control of on / off valves, it avoids mechanical wear and electrical shocks caused by frequent pump start-stop cycles. This fundamentally solves the core problem of pump damage, significantly reduces the failure rate of the dispensing head cleaning system, and improves the stability and reliability of the entire dispensing equipment.

[0016] 3. The gravity-fed supply system has a simple structure and eliminates the need for complex pump control systems and power sources. This not only reduces the initial manufacturing cost of the system but also lowers the workload of daily maintenance and subsequent maintenance and replacement costs. Furthermore, the system operates without a pump, achieving energy savings.

[0017] 4. Due to stable liquid levels and a significantly reduced system failure rate, the dispensing head cleaning process is smooth and reliable, effectively avoiding dispensing interruptions and reduced dispensing quality caused by incomplete cleaning or equipment malfunctions. This ensures the continuity and stability of the dispensing production process, thereby improving the overall production efficiency of dispensing operations. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1-3 As shown, this utility model discloses a drip-type adhesive removal device, including an adhesive removal box 1 filled with adhesive remover. An insertion interface 11 is provided at the upper end of the adhesive removal box 1 for inserting an adhesive dispensing head. The insertion interface 11 is rectangular and has a floating sponge plate 5 on the liquid surface. The sponge plate 5 is saturated with adhesive remover. The adhesive dispensing head contacts the sponge plate 5, removing adhesive from its surface. The sponge plate 5 is fitted with the inner wall of the insertion interface 11 with a gap, and the height of the upper surface of the sponge plate 5 is higher than the height of the lower surface of the top plate of the adhesive removal box 1. This limits the position of the sponge plate 5, ensuring its stability within the insertion interface 11. The sponge plate 5 has the following advantages: 1. The sponge plate 5 covers the liquid surface of the insertion interface 11, forming an isolation barrier, which significantly reduces the direct exposure of the adhesive remover to the air, effectively inhibiting its volatilization. This not only saves on adhesive remover consumption but also reduces potential pollution to the working environment. 2. When the dispensing head is inserted into the adhesive release tank 1 through the insertion interface 11, its surface will first come into contact with the moistened sponge plate 5. While absorbing sufficient adhesive release agent, the sponge plate 5 can also perform preliminary wiping of the dispensing head surface, assisting in the removal of adhering adhesive and improving cleaning effect and efficiency. 3. The sponge plate 5 floats on the liquid surface, possessing a certain degree of damping and buffering effect. When the dispensing head is inserted or withdrawn, the sponge plate 5 can absorb some of the liquid surface impact, reducing drastic fluctuations in the adhesive release agent level and providing assistance in maintaining a stable liquid level.

[0022] An inlet is located on the side of the dissolving tank 1 near the top. A glue container 2 for filling dissolving agent is located above the dissolving tank 1, and an outlet is located at the bottom of the glue container 2. The inlet and outlet are connected by a glue delivery pipe 3. An on / off valve 4 is installed on the glue delivery pipe 3 to control the flow of glue, thus allowing the glue container 2 to replenish glue to the dissolving tank 1 or stop replenishing glue.

[0023] Manual operation of the on / off valve 4 is inefficient and prone to errors. Therefore, in this embodiment, the on / off valve 4 is a solenoid valve, preferably a corrosion-resistant solenoid valve, to improve its service life. The degumming tank 1 is equipped with a high-level sensor 6 and a low-level sensor 7 arranged vertically. The high-level sensor 6 controls the on / off valve 4 to close; the low-level sensor 7 controls the on / off valve 4 to open. This achieves automatic glue replenishment in the degumming tank 1.

[0024] Since the amount of glue in the dispensing tank 1 is only needed to clean the surface of the dispensing head, the required amount of glue is small, resulting in a small volume of the dispensing tank 1. This means the dispensing tank 1 does not have sufficient height to install a liquid level sensor. Therefore, a high-level detection tube 8 and a low-level detection tube 9 are installed on the dispensing tank 1. The high-level detection tube 8 and the low-level detection tube 9 are U-shaped with their openings facing upwards and have two side arms, one long and one short. The upper end of the short side arm is connected to and communicates with the bottom of the dispensing tank 1, while the long side arm is higher than the highest liquid level in the dispensing tank 1. The high-level sensor 6 is installed on the long side arm of the high-level detection tube 8; the low-level sensor 7 is installed on the long side arm of the low-level detection tube 9. The length of the long side arm is greater than the height of the dispensing tank 1, thus providing sufficient installation space for the liquid level sensor. Utilizing the principle of communicating vessels, the liquid level in the detection tube is consistent with the liquid level in the dispensing tank 1, and the liquid level can be detected by measuring the liquid level in the detection tube.

[0025] Compared to existing technologies, the advantages of this embodiment are: 1. By placing the glue tank 2 containing the dissolving agent above the dissolving tank 1, the dissolving agent is continuously and naturally replenished into the dissolving tank 1 via the glue delivery pipe 3, utilizing its own gravity. This liquid level balance mechanism based on the principle of communicating vessels can automatically compensate for liquid level fluctuations caused by the immersion of the dispensing head and solvent evaporation, thereby stably maintaining the liquid level at a preset height, ensuring that the dispensing head is fully immersed each time, achieving a reliable and consistent cleaning effect. 2. This utility model replaces the traditional method of relying on frequent pump start-stop to replenish the dissolving agent. Through gravity-fed supply and the coordinated control of the on / off valve 4, it avoids mechanical wear and electrical shocks caused by frequent pump start-stops. This fundamentally solves the core problem of pump damage, significantly reduces the failure rate of the dispensing head cleaning system, and improves the stability and reliability of the entire dispensing equipment. 3. The gravity-fed supply system has a simple structure and does not require a complex pump control system and its power source. This not only reduces the initial manufacturing cost of the system but also reduces the workload of daily maintenance and subsequent maintenance and replacement costs. Meanwhile, the system operates without a pump, achieving energy savings. 4. Due to stable liquid levels and a significantly reduced system failure rate, the dispensing head cleaning process is smooth and reliable, effectively avoiding dispensing interruptions and reduced dispensing quality caused by incomplete cleaning or equipment malfunction. This ensures the continuity and stability of the dispensing production process, thereby improving the overall production efficiency of dispensing operations.
