Description

Technical Field

[0001] This utility model relates to the field of mechanical design and automation technology, and in particular to an automatic cleaning dispensing machine. Background Technology

[0002] In industries such as precision electronics manufacturing, semiconductor packaging, and medical devices, the dispensing process is a critical production step, and its quality directly affects the reliability and performance of products. While traditional dispensing equipment has made significant progress in dispensing accuracy and automation over the years, it still faces the following technical limitations in actual production: Current mainstream dispensing equipment generally lacks an integrated workpiece pretreatment system. Before dispensing, the workpiece surface may retain dust, oil, or processing debris from previous steps. These contaminants can lead to reduced adhesive bonding strength and abnormal conductivity. Existing solutions typically require an additional independent cleaning station, increasing equipment footprint and extending production cycle time. Furthermore, fast-drying adhesives (such as UV adhesives and instant adhesives) tend to solidify and accumulate at the dispensing head exit. Traditional equipment often relies on manual scraping or solvent immersion for maintenance, resulting in short maintenance intervals.

[0003] Therefore, there is a particular need for a dispensing machine that can automatically clean the workpiece and the dispensing head to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies, such as insufficient workpiece cleaning affecting dispensing quality and easy clogging of dispensing heads requiring frequent maintenance, this utility model provides an automatic cleaning dispensing machine.

An air jet head 10 is welded to the right side of the rotating shaft 7. A glue delivery pipe 11 is connected to the upper end of the dispensing head 9. A glue tank 131 is welded to the left side of the gantry frame 2. A constant temperature chamber 13 is bolted to the left side of the gantry frame 2. The constant temperature chamber 13 is located outside the glue tank 131 and is used to maintain a stable glue temperature. A water tank is fixed to the upper inner side of the glue tank 131. Pump 12 and glue delivery hose 11 are connected at one end to the upper end of the dispensing head 9, and at the other end, they extend through the top of the slide plate 4 and the top of the gantry 2 and connect to the water pump 12. Air delivery hose 111 is connected to the upper end of the jet nozzle 10. A dry ice cleaning machine 14 is bolted to the right side of the gantry 2. Rotary doors are rotatably connected to the front of the constant temperature chamber 13 and the upper side of the dry ice cleaning machine 14 for easy maintenance and material replacement. An air pump 15 is fixedly connected to the front of the dry ice cleaning machine 14. The output end of the air pump 15 is connected to a second air delivery hose 16. The outlet of the second air delivery hose 16 faces the outer surface of the dispensing head 9 and is used to spray dry ice to clean residual glue. The upper end of the first air delivery hose 111 is connected to the upper end of the jet nozzle 10 and extends along... The top right side of the slide plate 4 is extended, and the lower end of the first air pipe 111 is fixedly connected to the rear side of the second air pipe 16. A valve 17 is rotatably connected to the second air pipe 16. The lower side of the gantry frame 2 is bolted with symmetrical hot air blowers 18. The two hot air blowers 18 are arranged opposite each other to accelerate the curing of glue or dry the residual solvent after cleaning. The top of the machine body 1 is bolted with a linear module 19. The front side of the machine body 1 is fixed with a controller 24. The first electric slide rail 3, the second electric slide rail 5, the geared motor 8, the water pump 12, the constant temperature box 13, the air pump 15, the valve 17, the hot air blower 18 and the linear module 19 are electrically connected to the controller 24. The linear module 19 is equipped with a clamping mechanism.

[0022] like Figure 5As shown, the clamping mechanism includes a placement platform 20, guide rods 22, clamping blocks 21, and springs 23. The placement platform 20 is welded onto the slider of the linear module 19 and moves along the upper side of the linear module 19. The placement platform 20 is slidably connected to the left and right symmetrical guide rods 22. The opposite end of the guide rods 22 is welded to the clamping block 21. The clamping block 21 and the placement platform 20 are connected by a spring 23 for clamping the workpiece.

[0023] When the workpiece needs to be glued, first place the machine body 1 on a horizontal table. Turn on the constant temperature chamber 13 and hot air blower 18 through the controller 24. The constant temperature chamber 13 starts working, maintaining the temperature of the glue in the glue tank 131 at the set value. The hot air blower 18 preheats to the working temperature. Then, the operator pulls either side of the guide rod 22 outward. The guide rod 22 moves the corresponding clamping block 21 and compresses the spring 23, placing the workpiece in the center of the placement table 20. Release the guide rod 22. The restoring force of the spring 23 causes the clamping blocks 21 on both sides to clamp the workpiece synchronously. Turn on the linear module 19 through the controller 24. 19. Move the workpiece to the required position, then activate the electric slide rail 1 (3), electric slide rail 2 (5), and geared motor 8 via controller 24. Electric slide rail 1 (3) drives the slide plate 4 to move laterally along the gantry frame 2, and electric slide rail 2 (5) drives the mounting plate 6 to move longitudinally. The output shaft of geared motor 8 drives the rotating shaft 7 to rotate 90°, aligning the jet nozzle 10 with the workpiece. Activate the dry ice cleaning machine 14 and air pump 15 via controller 24. Air pump 15 supplies air to the jet nozzle 10 through air supply pipe 111. The jet nozzle 10 sprays airflow to perform preliminary cleaning on the workpiece surface. After cleaning, activate controller 24. The air pump 15 is turned off, and the output shaft of the geared motor 8 is reversed by 90° via the controller 24, aligning the dispensing head 9 with the workpiece. The water pump 12 is turned on via the controller 24, and the adhesive in the glue tank 131 is delivered to the dispensing head 9 through the glue delivery pipe 11. The dispensing head 9 performs precise dispensing according to the preset trajectory. The hot air blower 18 blows hot air to accelerate the curing of the adhesive on the workpiece surface. After dispensing is completed, the water pump 12 is turned off via the controller 24 to stop the glue supply. The dispensing head 9 is then moved back to its original position via the controller 24. The air pump 15 and valve 17 are turned on via the controller 24, and the air pump 15 delivers dry adhesive to the workpiece. Ice particles are sprayed through air supply pipe 16. The dry ice jet precisely acts on the outer surface of the dispensing head 9, thoroughly removing the solidified adhesive on the dispensing head 9 through low-temperature embrittlement and impact. After the dispensing head 9 is cleaned, the air pump 15 and valve 17 are turned off by controller 24. The operator pulls any guide rod 22 to release the clamp 21 and remove the completed workpiece. Releasing the guide rod 22 causes the clamp 21 to automatically reset. When no operation is required, the constant temperature chamber 13, hot air blower 18, linear module 19, electric slide rail 1 3, electric slide rail 2 5, geared motor 8 and dry ice cleaning machine 14 are turned off by controller 24.
