Description

Technical Field

[0001] This utility model relates to a multifunctional automatic glue spraying device, belonging to the technical field of glue spraying equipment. Background Technology

[0002] In existing technologies, automatic glue spraying devices have been widely used in fields such as electronic packaging, automobile manufacturing, and furniture gluing. However, traditional glue spraying devices have two prominent pain points: First, when switching glue materials or during long-term shutdowns, residual glue in the spray head is very easy to solidify, causing nozzle blockage. Cleaning and maintenance are cumbersome and time-consuming, seriously affecting production efficiency. Second, common cleaning mechanisms have limited functions, mostly simple solvent rinsing or air blowing, which are not thorough. They are ineffective in treating high-viscosity glues or partially solidified colloids, and lack effective treatment of waste liquid after cleaning.

[0003] Although some technical solutions attempt to set up cleaning stations, most of them are simple soaking or one-way rinsing. Their motion control, cleaning thoroughness and automation are insufficient, and they cannot form a closed-loop care for the spray nozzle in an all-round and multi-layered manner.

[0004] Therefore, there is an urgent need in this field for a multifunctional adhesive spraying device that can achieve efficient, thorough, and fully automated cleaning and anti-clogging. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-7 As shown, a multifunctional automatic glue spraying device includes a workbench 1, a support frame 2 fixedly installed on the upper surface of the workbench 1, a slidable glue spraying component 3 on the top of the support frame 2, and a drive assembly 4 on the top of the support frame 2 for the glue spraying component 3 to slide. The glue spraying component 3 includes a glue storage tank 301 and a glue spraying head 302. A cleaning station 5 is provided on the upper surface of the workbench 1. The cleaning station 5 is provided with a rinsing chamber 501, a blowing chamber 502, and an adsorption chamber 503, so as to thoroughly clean the glue spraying head 302 through the cleaning station 5. Compared with the single-function cleaning unit in the prior art, this device physically integrates the three functional chambers of rinsing, blowing, and adsorption, but isolates their functions in a cleaning station 5. This allows the glue spraying head 302 to complete the entire process of deep cleaning with liquid solvent, powerful blowing with gaseous medium, and vacuum adsorption of residual droplets in a preset process sequence, without interference, and with automated care.

[0026] Drive assembly 4 includes a transverse frame 401, a transverse lead screw 402, and a transverse drive motor 403. The transverse frame 401 is fixedly mounted on the top of the support frame 2. The transverse lead screw 402 is rotatably mounted inside the transverse frame 401. The transverse drive motor 403 is fixedly mounted on one side surface of the support frame 2 and is fixedly connected to the transverse lead screw 402. A longitudinal frame 404 is slidably connected to the transverse lead screw 402. A longitudinal guide rod 405 is provided on the support frame 2, and the longitudinal guide rod 405 passes through the longitudinal frame 404. A longitudinal lead screw 406 is rotatably mounted inside the longitudinal frame 404. One end of the longitudinal frame 404 is fixed... A longitudinal drive motor 407 is fixedly installed, and the output end of the longitudinal drive motor 407 is fixedly connected to one end of the longitudinal lead screw 406. It should be noted that a position sensor (such as an infrared position sensor, which is a common position detection sensor on the market, so it is not described in this device) can be installed above the glue spraying head 302 of the glue spraying part 3, so as to connect with an external controller and control the position adjustment of the glue spraying head 302. The set transverse drive motor 403 and longitudinal drive motor 407 can drive the set lead screw, thereby realizing the position movement of the glue spraying head 302.

[0027] A support base 408 is slidably installed inside the longitudinal frame 404. The support base 408 is slidably engaged within the longitudinal frame 404, and is slidably connected to the longitudinal lead screw 406. An adjusting electric actuator 409 is fixedly installed at the lower end of the support base 408. The lower end of the adjusting electric actuator 409 is fixedly connected to the glue storage tank 301. The lower end of the glue storage tank 301 is connected to the glue spray head 302 via a pipe. A support plate 7 is fixedly installed on the lower surface of the workbench 1 via a support rod 6. Limit rods 8 are evenly arranged on the upper surface of the support plate 7. Limit sleeves 9 are evenly fixedly installed on the lower surface of the cleaning station 5. The limit sleeves 9 are slidably engaged with the limit rods 8. A lifting cylinder 10 is fixedly installed on the upper surface of the support plate 7. The top of the lifting cylinder 10 is fixedly connected to the cleaning station 5. It should be noted that... By adjusting the setting of the electric actuator 409, not only can the precise height adjustment of the spray nozzle 302 in the Z-axis direction be achieved to adapt to different workpieces, but more importantly, when the spray nozzle 302 enters the cleaning station 5, it can be controlled by the program to make it contact the bottom of the cleaning chamber or the sealing structure with a constant micro pressure, which plays a role in flexible docking and buffering, avoiding damage to the precision nozzle from rigid collisions. It should also be noted that by controlling the lifting cylinder 10 through the external controller, the lifting adjustment of the cleaning station 5 can be controlled with the cooperation of the limit rod 8 and the limit sleeve 9, so as to cooperate with the cleaning of the spray nozzle 302.

[0028] Multiple cleaning rollers 11 rotate within the rinsing chamber 501. Synchronous gears 12 are fixedly mounted at the lower ends of each cleaning roller 11, and these gears mesh with each other. The synchronous gears 12 are located on the lower surface of the cleaning station 5. A synchronous motor 13 is connected to one of the synchronous gears 12, and a motor housing 14 is fixedly mounted on the synchronous motor 13. The motor housing 14 is fixedly connected to the lower surface of the cleaning station 5. A water passage chamber 15 is formed around the inner wall of the rinsing chamber 501, and rinsing nozzles 16 are evenly distributed along the inner wall. A water pump 17 is fixedly mounted on the upper surface of the support plate 7, and the outlet of the water pump 17 is connected to the rinsing station 5. Pipes connect the spray nozzles 16. A water outlet 18 is provided at the bottom of the rinsing chamber 501. A water collection tank 19 is fixedly installed on the upper surface of the support plate 7. The water collection tank 19 and the water outlet 18 are connected by pipes. It should be noted that multiple cleaning roller brushes 11 are driven to rotate synchronously in opposite directions by the synchronous gear 12. When the spray nozzle 302 descends into the rinsing chamber 501, the rotating roller brushes can perform all-round, no-dead-angle mechanical scraping and brushing on the outer wall of the spray nozzle. This design is especially suitable for high viscosity and easy stringing adhesives. It can effectively break and peel off cured or semi-cured adhesives that are difficult to remove by solvents alone, solving the stubborn problems in traditional technology.

[0029] The inner walls at both ends of the purge chamber 502 are provided with air blowing chambers, and air blowing holes 20 are evenly distributed on one side of each air blowing chamber. Blowers 21 are symmetrically arranged on the upper surface of the support plate 7, and the blowers 21 are connected to the air blowing chambers via pipes. A suction head 22 is fixedly installed at the bottom of the adsorption chamber 503, and a vacuum pump 23 is fixedly installed on the upper surface of the support plate 7. The vacuum pump 23 is fixedly connected to the suction head 22 via pipes. It should be noted that the purge chamber 502 uses symmetrically arranged air blowing holes 20 on both sides, which can create a sandwich effect of airflow on the spray nozzle 302 from two directions, thereby quickly and evenly dispersing and removing large droplets and solvents adhering to the nozzle. The purge efficiency is much higher than that of single-sided blowing, and even after high-pressure purge, the nozzle tip may still be affected by... The capillary action suspends extremely fine droplets, and the adsorption system consisting of vacuum pump 23 and suction head 22 can actively suck up such residual droplets to achieve ultimate drying. This ensures that the spray head 302 is in an absolutely clean and dry state after cleaning, completely eliminating problems such as glue performance changes or leakage during the next spraying due to residual droplets, thus ensuring product yield. It should be noted that during the rinsing, blowing and adsorption process of the spray head 302, the device needs to be programmed through an external controller and then used in conjunction with a position sensor to realize the lifting and lateral movement of the spray head 302, thereby achieving a complete cleaning of the spray head 302. Since the sensor and external controller are common existing technologies on the market, their structure is not described in this device.
