Description

Technical Field

[0001] This utility model relates to the field of glue dispensing device technology, specifically a glue dispensing device for instrument manufacturing. Background Technology

[0002] A glue-filling device is a specialized device used to precisely fill glue, sealant, or other similar adhesives into specific containers, parts, or products. It has wide applications in the instrument manufacturing industry. Glue filling can prevent rainwater, dust, and other contaminants from entering the instrument, thereby extending the instrument's service life.

[0003] The glue dispensing device needs to be cleaned regularly because residual glue will adhere to the inner wall of the container, and after a period of time, it will solidify and deteriorate. When new glue mixes with the solidified glue, it will affect the quality of the new glue. The usual method is to first manually spray the solvent onto the inner wall of the container, wait for the glue to dissolve, and then proceed with the cleaning. However, manual spraying is prone to inaccurate dosage, waste of solvent, and incomplete spraying, which affects the cleaning effect of the solidified glue.

[0004] In order to improve the uniformity of the distribution of the solvent in the container, reduce the waste of the solvent, and improve the cleaning effect of the solidified glue, this application proposes a glue dispensing device for instrument manufacturing. Utility Model Content

[0008] Further description: The top of the cleaning disc has several air vents located between the annular box and the cap, and the bottom of the cleaning disc has a storage groove in the middle of the front side; here, the cleaning disc is located at the position of the cap and has a through hole, with the storage groove and the hole passing through each other.

[0009] Further description: An electric push rod two is fixedly connected to the top of the inner wall of the cap, and a scraper is fixedly connected to the driving end of the electric push rod two. The outer wall of the scraper is set on the inner wall of the collection groove. Here, the electric push rod two acts as a linear drive, which can push the scraper to move downward. The bottom of the scraper is flat, the force-bearing area is reduced, and the scraping pressure is increased.

[0010] Further description: A connecting plate is fixedly connected to the upper left side of the glue bucket, and a motor is fixedly connected to the inner wall of the left side of the top of the connecting plate. A gear is fixedly connected to the drive end of the motor; here, the motor acts as the power device for the gear and provides rotation.

[0011] Further description: A toothed ring is fixedly connected to the lower side of the outer wall of the end cap, and the left end of the outer diameter of the toothed ring is meshed with the right end of the outer diameter of the gear; here, the toothed ring and the gear are a simple transmission mechanism.

[0012] Further description: A hot air blower is fixedly connected to the right side of the top of the end cap, and the output end of the hot air blower passes through the inner wall of the end cap and is fixedly connected to an exhaust pipe; here, the hot air blower is existing equipment that can generate hot air and the temperature can be adjusted.

[0013] Further description: A glue injection tube is fixedly connected to the upper right side of the glue bucket, and a glue dripping tube is fixedly connected to the front bottom of the glue bucket. Mounting brackets are fixedly connected to the lower left and right sides of the glue bucket.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-4A glue-pouring device for instrument manufacturing includes a glue bucket 1, an end cap 2 rotatably connected to the top of the glue bucket 1, an electric push rod 8 fixedly connected to the inner wall of the middle part of the top of the end cap 2 and passing through the upper and lower sides of the end cap 2, a cap 15 fixedly connected to the driving end of the electric push rod 8, a cleaning disc 13 fixedly connected to the bottom end of the cap 15, an annular box 14 fixedly connected to the outer side of the top of the cleaning disc 13, a plurality of liquid storage chambers 21 are opened on the outer side of the inner wall of the cleaning disc 13, and abrasive balls 18 are installed on the outer side of the inner wall of each liquid storage chamber 21. An outlet pipe 22 is fixedly connected to the bottom end of the annular box 14 above the liquid storage chamber 21. The bottom end of the outlet pipe 22 passes through the inner wall of the liquid storage chamber 21. A spring hose 16 is fixedly connected to the front left part of the top of the annular box 14. An injection pipe 6 is fixedly connected to the inner wall of the front left part of the top of the end cap 2 and passes through the upper and lower sides of the end cap 2. The bottom end of the injection pipe 6 is fixedly connected to the other end of the spring hose 16.

[0024] To further explain, before cleaning the glue bucket 1, first connect the upper end of the injection pipe 6 to the discharge port of the container containing the solvent. After the connection is made, open the valve knob of the injection pipe 6. The solvent will flow into the annular box 14 along the injection pipe 6 and the spring hose 16, and then enter the storage chamber 21 through the outlet pipe 22 until it is full. Then close the valve knob and the cleaning work can be started.

[0025] The electric push rod 8 is activated. Its operation mode has been pre-set in the controller, which is located on the front top of the end cover 2. It can control multiple electric drive components in this device. The drive end of the electric push rod 8 will drive the cap 15 and the cleaning disc 13 below it to move up and down in the glue tank 1. When the cleaning disc 13 moves, multiple abrasive balls 18 on the outer wall roll due to friction with the inner wall of the glue tank 1. At the same time, the solvent in the liquid storage chamber 21 is rolled onto the glue solidified on the inner wall of the glue tank 1. Meanwhile, the hot air blower 7 starts to work and generates hot air. The hot air is discharged into the glue tank 1 through the exhaust pipe 17 and the air outlet 20 to accelerate the dissolution of the solidified glue. When the glue begins to dissolve, the abrasive properties of the abrasive balls 18 are used to scrape the glue, causing the glue to fall off quickly. Example

[0026] Please see Figures 1-2 as well as Figure 5Further, based on Embodiment 1, the top of the cleaning disc 13 is provided with several air outlets 20 located between the annular box 14 and the cap 15. A storage groove 19 is provided in the middle of the front side of the bottom end of the cleaning disc 13. A hot air blower 7 is fixedly connected to the right side of the top of the end cap 2. The output end of the hot air blower 7 penetrates the inner wall of the end cap 2 and is fixedly connected to an exhaust pipe 17. An electric push rod 23 is fixedly connected to the top of the inner wall of the cap 15. A scraper 24 is fixedly connected to the driving end of the electric push rod 23. The outer wall of the scraper 24... A connecting plate 9 is fixedly connected to the upper left side of the glue bucket 1, and a motor 10 is fixedly connected to the inner wall of the top left side of the connecting plate 9. A gear 11 is fixedly connected to the drive end of the motor 10. A toothed ring 12 is fixedly connected to the lower outer wall of the end cap 2. The left end of the outer diameter of the toothed ring 12 is meshed with the right end of the outer diameter of the gear 11. A glue injection tube 3 is fixedly connected to the upper right side of the glue bucket 1. A dripping tube 4 is fixedly connected to the front bottom of the glue bucket 1. Mounting brackets 5 are fixedly connected to the lower left and right sides of the glue bucket 1.

[0027] To further explain, during the up-and-down movement of the cap 15 and cleaning disc 13 driven by the electric push rod 8, the motor 10 is started, which drives the gear 11 to rotate. The gear ring 12 that meshes with it will cause the end cap 2 to rotate accordingly. In this way, the abrasive ball 18 can not only roll the solvent up and down on the inner wall of the glue bucket 1, but also roll it on each side wall of the glue bucket 1, so that the solvent is evenly distributed in the glue bucket 1, effectively improving the glue dissolving efficiency.

[0028] Afterwards, the hot air blower 7 continues to run, further increasing the temperature of the dissolved glue that falls to the bottom of the inner wall of the glue bucket 1. The heat is transferred to the glue that has solidified at the bottom of the inner wall of the glue bucket 1, which helps the glue dissolve. With the help of the controller, the electric push rod 8 pushes the cap 15 and the cleaning plate 13 to a position near the bottom of the inner wall of the glue bucket 1. Then, the electric push rod 23 is started to push the scraper 24 out of the collection slot 19 so that its bottom end contacts the bottom of the inner wall of the glue bucket 1. Then, the motor 10 is started again. With the help of the gear 11 and the gear ring 12, the end cap 2 drives the electric push rod 8 to rotate. The scraper 24 stirs the dissolved glue, so that the heat is evenly distributed and the dissolving process is accelerated. The bottom end of the scraper 24 can scrape off the glue that has solidified at the bottom of the inner wall of the glue bucket 1, speeding up the cleaning. After cleaning, the valve knob of the drip tube 4 is opened to drain the glue.

[0029] Working principle: First, before cleaning the glue bucket 1, connect one end of the injection pipe 6 to the discharge port of the container containing the solvent. After the connection is completed, open the valve knob on the injection pipe 6 so that the solvent flows into the annular box 14 along the injection pipe 6 and the spring hose 16, and then flows into the storage chamber 21 along the outlet pipe 22 until it is full. Then close the valve knob and start the cleaning work.

[0030] When the electric push rod 8 is started, it will move up and down inside the glue bucket 1, forming a reciprocating motion. Since the electric push rod 8 is pre-set to operate and controlled by the controller, the drive end of the electric push rod 8 will drive the cap 15 and the cleaning disc 13 at the bottom to move up and down inside the glue bucket 1. During the movement of the cleaning disc 13, multiple abrasive balls 18 on the outer wall will roll due to friction with the inner wall of the glue bucket 1, and at the same time, the solvent in the liquid storage chamber 21 will be rolled onto the surface of the solidified glue on the inner wall of the glue bucket 1. At the same time, the hot air blower 7 is turned on to generate hot air, which is discharged into the glue bucket 1 through the air outlet 20 through the exhaust pipe 17, thereby accelerating the dissolution of the solidified glue. After the glue begins to dissolve, the abrasive effect of the surface of the abrasive balls 18 will be used to scrape the glue, thereby accelerating the removal of the glue.

[0031] While the electric push rod 18 drives the cap 15 and cleaning disc 13 to move up and down, the motor 10 is started, causing the gear 11 to rotate. The gear ring 12, which is meshed on one side of the gear 11, then drives the end cap 2 to rotate. This allows the abrasive ball 18 to not only coat the inner wall of the glue bucket 1 from top to bottom, but also coat each side of the glue bucket 1, so that the solvent is evenly distributed in the glue bucket 1, improving the efficiency of glue dissolution.

[0032] Subsequently, as the hot air blower 7 continues to operate, the temperature of the dissolved glue that falls onto the bottom of the inner wall of the glue bucket 1 continues to rise, thereby transferring heat to the solidified glue on the bottom of the inner wall of the glue bucket 1, which helps to dissolve the solidified glue. By using the controller, the electric push rod 8 is operated to push the cap 15 and the cleaning plate 13 to a position close to the bottom of the inner wall of the glue bucket 1. Then, the electric push rod 23 is operated to start, pushing the scraper 24 out of the collection slot 19, so that the bottom of the scraper 24 contacts the bottom of the inner wall of the glue bucket 1. Then, the motor 10 is started, so that the end cap 2 drives the electric push rod 8 to rotate again, causing the scraper 24 to stir the dissolved glue, so that the heat is evenly distributed and the dissolution efficiency is accelerated. In addition, the bottom of the scraper 24 has a scraping effect on the solidified glue, which can speed up the cleaning of the solidified glue on the bottom of the inner wall of the glue bucket 1. After cleaning, the valve knob of the drip tube 4 is opened to allow the glue to be discharged.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
