Description

An automatic dispensing machine Technical Field

[0001] This utility model relates to the field of dispensing machines, specifically to an automatic dispensing machine. Background Technology

[0002] A dispensing machine is a device used for spraying coatings onto the surface of parts. When spraying coatings onto parts, a dispensing machine is used to treat the surface of the parts. It is also called a glue applicator, dripping machine, glue applicator, or potting machine. It is specifically designed to control fluids and apply them to the surface or interior of products. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of dispensing machines.

[0003] Existing automatic dispensing machines mainly consist of four parts: an adhesive supply system, a motion control system, a dispensing valve, and a control system. The control system operates the dispensing machine by using air pressure or a mechanical pump to drive the adhesive from the glue tank through pipelines to the dispensing valve. Commonly used adhesive types include epoxy resin, silicone, and UV adhesive. The valve needle is pneumatically or electrically controlled to open and close, and the adhesive is extruded from the nozzle using air pressure or mechanical pressure to form a preset dispensing pattern.

[0004] However, although existing dispensing machines have achieved automated production, the following technical bottlenecks still exist. In some existing dispensing machines, the glue supply system is driven by air pressure to squeeze the glue in the glue storage tank. However, due to the influence of air pressure fluctuations, the glue output is unstable, the glue dots are inconsistent, and high viscosity glue is prone to dry spraying, stringing, or glue breakage when conveying, which affects the dispensing quality and thus affects the stable supply of glue to the dispensing machine, which is not conducive to the reliable use of the dispensing machine. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide an automatic dispensing machine to solve the technical problem in the prior art where the dispensing of adhesive is unstable when air pressure fluctuates, thus affecting the stable dispensing of adhesive.

[0006] The objective of this utility model is achieved through the following means:

[0007] An automatic dispensing machine includes a base and a frame mounted on the base. A material handling mechanism is connected to the frame via a transverse module. A movable mounting slide is connected to the base via a movable module. A fixture is detachably connected to the mounting slide. The material handling mechanism includes a lifting module, a material handling cylinder and a material handling valve mounted on the lifting module. The telescopic end of the material handling cylinder extends toward the mounting slide and is connected to a lifting block. The material handling valve is mounted on the lifting block, allowing the material handling cylinder to drive the lifting block to move the material handling valve toward the mounting slide. A glue storage tank is connected to the lifting module via a connecting plate. A dispensing valve is connected to the glue outlet end of the glue storage tank. A stirring motor is connected to the lifting module via a mounting block. The stirring motor extends toward the glue storage tank via a telescopic screw and is connected to a stirring rod. The stirring motor can drive the stirring rod to rotate and perform lifting and lowering actions via the telescopic screw.

[0008] Furthermore, as described above, the lifting module is connected to a lifting plate that can be raised and lowered. A support base is connected to the side of the lifting plate. A guide rod is connected to the support base through a guide groove. One end of the guide rod is connected to the lifting block. A material-picking cylinder is installed on the support base, and the telescopic end of the material-picking cylinder is connected to the lifting block.

[0009] By cooperating with the guide groove of the guide rod and the support base, the lifting block is ensured to move in a straight line under the drive of the picking cylinder, which improves the positioning accuracy and stability of the picking valve, avoids the dispensing position deviation caused by the picking valve shifting or shaking during the movement, and improves the subsequent dispensing positioning quality.

[0010] Furthermore, as described above, one end of the connecting plate is connected to the lifting plate, and the connecting plate is provided with a connecting frame for installing the glue storage tank. The glue storage tank is provided with a receiving groove, and a cover is connected to the glue storage tank. A screw sleeve is connected to the cover, and the screw sleeve has a threaded hole inside for mating with the telescopic screw rod, so that the telescopic screw rod can move axially along the threaded hole of the screw sleeve.

[0011] The stirring motor drives the stirring rod to rotate via a telescopic screw, which continuously stirs the high-viscosity adhesive in the storage tank, preventing the adhesive from settling or solidifying, improving the rheological properties of the adhesive, and reducing dry-spraying. At the same time, the telescopic screw drives the stirring rod to rotate and squeeze the adhesive, thereby stabilizing the amount of adhesive dispensed and improving the consistency of the adhesive dots.

[0012] Furthermore, as described above, sealing washers are fitted at both ends of the screw sleeve, and spirally wound stirring blades are provided on the outer surface of the stirring rod.

[0013] The sealing gasket effectively isolates the internal and external environments of the glue storage tank, preventing glue leakage or the entry of external impurities during the mixing process, avoiding glue curing or contamination, ensuring the sealing of the glue storage tank and the stability of glue dispensing, and extending the equipment maintenance cycle.

[0014] The spiral-shaped stirring blades further ensure the stirring of the glue in the storage tank, preventing the glue from settling or hardening and improving the rheological properties of the glue.

[0015] Furthermore, as described above, the transverse module is connected to a movable seat, and the material handling mechanism is mounted on the movable seat. The transverse module can drive the movable seat to move the material handling mechanism.

[0016] Furthermore, as described above, the side of the base is provided with a connecting groove, the frame can be moved and adjusted along the extension direction of the connecting groove, and the frame is connected to the connecting groove by bolts.

[0017] The frame can be adjusted and moved along the connecting groove and fixed with bolts, which makes it easy to adjust the frame position according to the size of the fixture or the product type, adapt to different production needs, improve the equipment's versatility and installation flexibility, and reduce the cost of equipment upgrades or modifications.

[0018] The beneficial effects of this invention are as follows: The stirring motor drives the stirring rod to rotate via a telescopic screw, enabling dynamic mixing and uniform stirring of the adhesive in the storage tank. This prevents high-viscosity adhesive from separating or solidifying during static storage and maintains the fluidity of the adhesive during dispensing, reducing issues such as dry-firing, stringing, or adhesive breakage at the dispensing valve, thus improving dispensing quality. Simultaneously, the stirring rod, driven by the telescopic screw, can move up and down, allowing it to reach the bottom of the storage tank to stir and settle the adhesive. Furthermore, during descent, it further compresses the adhesive, allowing it to be extruded under air pressure, ensuring stable dispensing through the dispensing valve. This guarantees a stable supply and uniform dispensing of the adhesive, effectively avoiding the impact of air pressure fluctuations on the dispensing volume and improving dispensing consistency.

[0028] By cooperating with the guide groove of the guide rod 20 and the support seat 19, the lifting block 10 is ensured to move in a straight line under the drive of the picking cylinder 8, which improves the positioning accuracy and stability of the picking valve 9, avoids the dispensing position deviation caused by the picking valve 9 shifting or shaking during the movement, and improves the subsequent dispensing positioning quality.

[0029] One end of the connecting plate 11 is connected to the lifting plate 18. The connecting plate 11 is provided with a connecting frame 21 for installing the glue storage tank 12. The glue storage tank 12 is provided with a receiving groove 22. The glue storage tank 12 is connected with a cover 23. The cover 23 is connected with a threaded sleeve 24. The inside of the threaded sleeve 24 is provided with a threaded hole 25 for matching the telescopic screw 16, so that the telescopic screw 16 can move along the axial direction of the threaded hole 25 of the threaded sleeve 24.

[0030] The stirring motor 15 drives the stirring rod 17 to rotate via the telescopic screw 16, which can continuously stir the high-viscosity glue in the glue storage tank 12, prevent the glue from settling or solidifying, improve the rheological properties of the glue, and reduce dry running. At the same time, the telescopic screw 16 can drive the stirring rod 17 to rotate and squeeze the glue, thereby stabilizing the glue output and improving the consistency of glue dots.

[0031] The two ends of the threaded sleeve 24 are fitted with sealing gaskets, and the outer surface of the stirring rod 17 is provided with spirally wrapped stirring blades 26.

[0032] The sealing gasket effectively isolates the internal and external environments of the glue storage tank 12, preventing glue leakage or the entry of external impurities during the mixing process, avoiding glue curing or contamination, ensuring the sealing performance and glue dispensing stability of the glue storage tank 12, and extending the equipment maintenance cycle.

[0033] The spiral-arranged stirring blades 26 further ensure the stirring of the adhesive in the adhesive storage tank 12, preventing the adhesive from settling or hardening and improving the rheological properties of the adhesive.

[0034] The transverse module 3 is connected to a movable seat, and the material picking mechanism is installed on the movable seat. The transverse module 3 can drive the movable seat to move the material picking mechanism.

[0037] The specific dispensing process in this embodiment is as follows:

[0038] Driven by the transverse module 3 and the lifting module 7, the picking cylinder 8, via the lifting block 10, drives the picking valve 9 to pick up the product and move it towards the mounting slide 5, forming precise control of the linear motion trajectory and improving the stability of the picking action. The product is placed on the fixture 6, and the product on the fixture 6 is dispensed through the dispensing valve 13. The stirring motor 15 drives the stirring rod 17 to rotate through the telescopic screw 16, and the stirring blade 26 realizes dynamic mixing and uniform stirring of the glue in the glue storage tank 12, preventing the high viscosity glue from standing, separating, or solidifying, and continuously maintaining the glue consistency during the dispensing process. The fluidity of water reduces the occurrence of dry spraying, stringing, or glue breakage in the dispensing valve 13, improving dispensing quality. At the same time, the stirring rod 17 can move up and down under the drive of the telescopic screw 16. Combined with the fixed position of the glue storage tank 12, it can reach the bottom of the glue storage tank 12 to stir and settle the glue. When descending, the spiral-set stirring blades 26 can further squeeze the glue, so that the glue, combined with the air pressure, can be stably dispensed through the dispensing valve 13, ensuring a stable glue supply and uniform dispensing. This effectively avoids the impact of air pressure fluctuations on the glue output and improves the consistency of dispensing.
