Description

Technical Field

[0001] This utility model belongs to the field of dispensing machine technology, specifically, it relates to a dispensing machine for anti-clogging quantitative dispensing. Background Technology

[0002] A dispensing machine, also known as an adhesive applicator, glue applicator, glue applicator, or glue dispensing machine, is an automated device specifically designed for fluid control, precisely dispensing or coating fluids onto the surface or interior of a product. Its core function is to accurately dispense, inject, coat, or drip liquids such as adhesives and paints at designated locations on a product, capable of performing various coating processes such as dotting, drawing lines, and creating circles or arcs. Among these, a quantitative dispensing machine (also known as a precision dispensing machine) can achieve continuous and stable quantitative dispensing operations based on preset dispensing parameters.

[0003] When the dispensing machine is stopped, the adhesive remaining in the dispensing needle is prone to solidification due to solvent evaporation, leading to needle clogging. Chinese invention patent CN115518835A proposes an anti-clogging solution by inserting the dispensing needle into an alcohol bottle during the dispensing interval, utilizing the dissolving effect of alcohol to delay adhesive solidification. However, this solution has certain limitations in practical applications: First, during high-frequency operations, the adhesive remaining in the dispensing needle mixes with the alcohol, and some of the mixture is discharged with the needle movement, causing the alcohol solution to gradually become cloudy and ineffective; second, when the dispensing needle is pulled out of the alcohol bottle, the alcohol and adhesive mixture adhering to the outer wall of the needle is easily flung out during movement, potentially contaminating the workpiece surface or affecting subsequent dispensing accuracy, adversely impacting processing quality.

[0047] The working principle of the glue dispensing machine of the embodiment is consistent with that of the prior art, and the specific operation will not be repeated. The unique working process of the device will be described in detail below:

[0048] Cleaning and maintenance of the glue dispensing machine after use

[0049] After the glue dispensing machine completes the work, the first moving assembly 31 and the second moving assembly 32 of the moving device 2 are first operated in cooperation to accurately position the glue dispensing head 3 above the solution box 5, then the pneumatic cylinder 34 drives the glue dispensing head 3 to move towards the solution box 5, so that the glue dispensing needle 4 gradually penetrates through the compression ring 9 and moves towards the hole 17 of the box cover 16.

[0050] The reset spring is arranged between the pressing ring 9 and the box cover 16, and is elastically deformed when the glue dispensing head 3 is pressed. With the continuous downward movement of the glue dispensing head 3, the pressing ring 9 drives the two side rod bodies 12 to slide in the notches 19, and then pushes the slide column 13 to move along the vertical grooves 22 of the triangular guide groove 10. In the initial state, the slide column 13 is located at the top end of the vertical groove 22, and when the slide column 13 contacts the one-way rotating plate 11, the one-way rotating plate 11 is pressed and rotates around the hinge shaft, and the reset force is provided by the torsion spring or the clockwork arranged at the hinge. The one-way rotating plate 11 is reset immediately under the action of the torsion spring, and the one-way passing structure is formed. When the slide column 13 moves to the bottom end of the vertical groove 22, the glue dispensing needle 4 has passed through the hole 17 and is completely immersed in the organic solution in the solution box 5 (the height of the solution is controlled to be not higher than the bottom of the slide plate 8 and not to contact the wiping pad 14 in a safety interval), so that the glue in the needle tube is effectively prevented from solidifying and blocking.

[0051] Pre-treatment before use of the glue dispensing machine

[0052] When the glue dispensing machine needs to be used again, the air cylinder 34 drives the glue dispensing head 3 to reset upward, at this time the pressing ring 9 loses external pressure and rises synchronously under the action of the reset spring, and drags the slide column 13 to move reversely along the triangular guide groove 10. Due to the blocking effect of the one-way rotating plate 11, the slide column 13 cannot return along the original vertical groove 22, but slides into the first inclined groove 23. Limited by the guide of the notches 19, the two side rod bodies 12 keep linear motion, drive the slide plate 8 to move oppositely in the sliding groove 18, and make the wiping pad 14 (made of sponge or water-absorbing pad material and quickly replaced through the buckle structure) mounted on the slide plate 8 tightly adhere to the outer wall of the glue dispensing needle 4.

[0053] In the rising process of the pressing ring 9, the slide column 13 first reaches the end of the first inclined groove 23, and then turns into the second inclined groove 24 and slides to the vertical groove 22 under the guidance. When the slide column 13 contacts the one-way rotating plate 11 again, the rotating plate 11 is pressed to rotate to allow the slide column to pass, and is reset to block the reverse sliding path, so as to ensure that the slide column 13 stably returns to the initial position at the top end of the vertical groove 22. In this process, the wiping pad 14 synchronously wipes the glue dispensing needle 4 with organic solution, so as to avoid the solution from splashing out and polluting the working area when the needle is lifted.

[0054] The wiping pad 14 adopts modular design and can be quickly disassembled and replaced through the existing buckle structure, so as to solve the pollution and residue problem of the traditional fixed cleaning component and significantly improve the equipment maintenance efficiency. The whole action process is realized through the automatic cleaning of the mechanical linkage mechanism, without manual intervention, so as to ensure that the glue dispensing needle 4 is kept clean in the standby state and effectively prolongs the service life of the equipment.

[0055] Advantages:

[0056] By setting the solution box 5 containing the organic solution on the operation table 1, the dispensing needle 4 can be inserted into the solution box 5 in the use gap, soaked in the organic solution, effectively avoiding the solidification of the residual glue inside the dispensing needle 4, and fundamentally solving the dispensing needle blockage problem;

[0057] The cleaning assembly 6 (the rotating roller 26, the belt 27 and the cleaning sponge 28 and the wiping pad 14) is arranged in the solution box 5, the dispensing needle 4 can be cleaned by the organic solution when being inserted, and the glue and solution mixture remaining on the outer wall can be scraped off by the cleaning sponge 28 and the wiping pad 14 when being pulled out, so that the glue droplets are prevented from being splashed out to contaminate the operation table 1;

[0058] The cleaning assembly 6 realizes position updating of the cleaning sponge 28 through the rotating roller 26, ensures that the dispensing needle 4 contacts the cleaning area each time, and improves equipment maintenance efficiency;

[0059] Through the mechanical linkage structure of the pressing ring 9, the rod body 12, the slide column 13 and the triangular guide groove 10, the dispensing needle can be automatically immersed in the organic solution in the solution box when descending, and the wiping pad 14 can be driven by the slide plate 8 to adhere to the outer wall of the dispensing needle 4 for wiping when ascending, without manual intervention, the action process is precisely controlled through the one-way rotating plate 11, the reset spring and other mechanisms, and the stability and reliability of the cleaning action are ensured;

[0060] The height of the organic solution in the solution box 5 is controlled in a safe interval that does not exceed the bottom of the slide plate 8 and does not contact the wiping pad 14, so that the wiping pad 14 is prevented from being directly soaked in the solution, and the wiping pad 14 is ensured to only dry and wipe the outer wall of the dispensing needle 4 when the dispensing needle 4 is pulled out, and the solution is prevented from being taken out to contaminate the working area.
