Description

Technical Field

[0001] The invention relates to the technical field of glue coating, and in particular to automatic quantitative glue coating equipment for aluminum substrates. Background Art

[0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided board is composed of a three-layer structure, namely the circuit layer copper foil, the insulation layer and the metal base layer. It is commonly found in LED lighting products and has two sides. The white side is for welding the LED pins, and the other side is the original color of aluminum. Generally, it will be coated with thermal conductive slurry and then contact the thermal conductive part. Aluminum substrates are widely used in electronics, lighting and other industries, and the gluing process is crucial to product quality and performance.

[0003] The existing aluminum substrate gluing equipment has some shortcomings: Due to the small thickness of aluminum substrates, they are prone to sticking when stacked. This makes it easy for multiple aluminum substrates to stick together during transportation, increasing the difficulty of separation and positioning and reducing production efficiency; During the production, transportation and storage of aluminum substrates, the surface is easily contaminated with dust and other impurities. If the impurities on the surface are not effectively removed, they will be mixed into the glue during glue coating, resulting in uneven glue coating, bubbles, and other problems, which seriously affect the glue coating quality; When applying glue to the surface of the aluminum substrate, the glue liquid tends to flow to and accumulate at the edge of the aluminum substrate due to its fluidity. The glue liquid will exceed the edge of the aluminum substrate, causing material waste and product appearance defects, affecting the final performance and reliability of the product.

[0004] Therefore, an automatic quantitative glue coating device for aluminum substrate is proposed. Summary of the invention

[0022] like Figures 1 to 11 As shown, an automatic quantitative glue coating device for aluminum substrates includes a frame 1, a conveying mechanism 2 is arranged inside the frame 1 to convey the aluminum substrate horizontally, a servo moving component 3 is arranged on the top surface of the frame 1, a pick-up frame 4 is fixedly connected to the movable part of the servo moving component 3, a ventilation hole 41 is opened in the middle of the pick-up frame 4, and a blowing component 5 is arranged in the ventilation hole 41, a vacuum suction cup 6 is vertically movably inserted on the surface of the pick-up frame 4, a first spring 7 is sleeved on the surface of the vacuum suction cup 6, and the two ends of the first spring 7 are respectively fixed to the first spring 7 and the surface of the pick-up frame 4, and the first spring 7 is fixed to the first spring 7 and the surface of the pick-up frame 4. A spring 7 is used to elastically connect the vacuum suction cup 6 and the picking frame 4. A protective cover 8 is fixedly installed on the top surface of the frame 1. A dust cleaning component 9 is arranged at the input end of the protective cover 8 and the top surface of the frame 1, so as to contact the surface of the aluminum substrate through the dust cleaning component 9 to clean the dust and impurities on the surface. Two groups of centering components 10 are symmetrically arranged on the top surface of the protective cover 8. Glue cleaning components 11 are respectively arranged on the surfaces of the two groups of centering components 10 and the protective cover 8. A quantitative glue coating component 12 is arranged on the surface of the frame 1 and between the two groups of centering components 10 to spray glue liquid on the surface of the aluminum substrate.

[0023] More specifically, the servo moving component 3 drives the pick-up frame 4 and the vacuum suction cup 6 on its surface to move, so as to pick up and transport the aluminum substrate to the surface of the conveying mechanism 2. While picking up and transporting the stacked aluminum substrates, the blowing component 5 allows the airflow to blow towards the top surface of the aluminum substrate to preliminarily remove dust and impurities on the surface of the aluminum substrate. At the same time, the first spring 7 realizes that the vacuum suction cup 6 and the pick-up frame 4 are elastically connected. The impact of the airflow can also cause the aluminum substrate to generate low-frequency vibration, so as to avoid the stacked aluminum substrates from sticking to each other and being difficult to separate when picking up the aluminum substrates, thereby ensuring that each picked-up aluminum substrate is a single piece. The conveying mechanism 2 is used to convey the aluminum substrate. Before the aluminum substrate enters the protective cover 8, its dust cleaning component 9 contacts the surface of the aluminum substrate to clean the dust and impurities on the surface of the aluminum substrate again, thereby improving the cleanliness of the aluminum substrate. The two groups of centering components 10 are symmetrically arranged to ensure that the aluminum substrate is always in the center during the conveying and gluing process, and the quantitative gluing component 12 can be used to spray glue on its surface to avoid uneven gluing or gluing failure due to position offset. The glue cleaning component 11 on the surface of the centering component 10 cleans the excess glue that flows to the edge of the aluminum substrate during the gluing process, thereby reducing the flow of excessive glue to the edge of the aluminum substrate. It should be noted that due to the fluidity of the glue and the tension of the liquid, the glue will flow to this place again after cleaning the glue at the edge of the aluminum substrate. Since the excess glue is cleaned, the glue accumulated at the edge will be reduced, making the glue coating smoother.

[0024] In some practical applications, a material table 13 is fixedly installed at the end of the frame 1 and below the servo moving assembly 3 to stack the aluminum substrates to be coated with glue.

[0025] More specifically, during the production process, the operator only needs to neatly stack a certain number of aluminum substrates on the material table 13 to provide sufficient material supply for the subsequent automatic loading and gluing processes, thereby achieving continuous and efficient production operations.

[0026] In some practical applications, the servo moving assembly 3 includes a vertical frame 301 fixedly mounted on the top surface of the frame 1, a frame 302 is fixedly mounted on the top surface of the frame 1 via the vertical frame 301, a servo motor 303 is fixedly mounted on one side wall of the frame 302, a threaded rod 304 is fixedly connected to the output end of the servo motor 303, two groups of guide rods 305 are installed on the inner walls of both sides of the frame 302 and parallel to the threaded rod 304, a movable frame 306 is threadedly sleeved on the surface of the threaded rod 304, the movable frame 306 and the two groups of guide rods 305 are movably sleeved, two groups of cylinders 307 are fixedly mounted on the top surface of the movable frame 306, the movable part of the cylinder 307 passes through the movable frame 306, and the picking frame 4 is fixedly mounted on the bottom end of the two groups of cylinders 307.

[0027] More specifically, the servo motor 303 is installed on a side wall of the frame 302 as a power source. The threaded rod 304 connected to its output end rotates under the drive of the servo motor 303. The rotation of the threaded rod 304 drives the movable frame 306 threadedly mounted thereon to move linearly along its guide rod 305, thereby realizing the horizontal position adjustment of the picking frame 4. The cylinder 307 on the movable frame 306 is used to realize the vertical position adjustment of the picking frame 4, thereby transferring the aluminum substrate on the material table 13 to the conveying mechanism 2 to realize automatic loading.

[0028] In some practical applications, the blowing assembly 5 includes a motor mounting frame 501 fixedly mounted on the surface of the ventilation hole 41, a motor 502 is fixedly plugged into the inner wall of the motor mounting frame 501, a fan blade 503 is fixedly connected to the output end of the motor 502, and the fan blade 503 is located inside the ventilation hole 41, a metal protective net 504 is fixedly mounted on the surface of the ventilation hole 41, and the metal protective net 504 is located above the motor mounting frame 501.

[0029] More specifically, the motor 502 serves as a power source, driving the fan blades 503 connected to its output end to rotate and drive the air flow, forming an airflow with a certain pressure and speed, which is ejected through the bottom end of the ventilation hole 41. When the vacuum suction cup 6 adsorbs the aluminum substrate and lifts it, the generated airflow is blown to the top surface of the aluminum substrate, and the dust and impurities on the surface of the aluminum substrate are removed by the airflow, thereby improving the cleanliness of the aluminum substrate. At the same time, the first spring 7 realizes the elastic connection between the vacuum suction cup 6 and the picking frame 4, and the impact of the airflow can also cause the aluminum substrate to produce low-frequency jitter, thereby preventing the aluminum substrates from sticking to each other and being difficult to separate when stacked, ensuring that the aluminum substrate picked up each time is a single piece, thereby improving production efficiency and product quality.

[0030] In some practical applications, the cleaning component 9 includes two groups of symmetrically arranged protrusions 901 fixedly installed on the end face of the input end of the protective cover 8, and a vertical rod 902 is fixedly installed on the bottom surface of the protrusion 901 and the top surface of the frame 1, a movable shaft 903 is movably sleeved on the surface of the vertical rod 902, a second spring 904 is sleeved on the surface of the vertical rod 902, and a self-adhesive roller 905 is rotatably sleeved on the surface of the movable shaft 903.

[0031] More specifically, when the conveying mechanism 2 conveys the aluminum substrate into the protective cover 8, the surface of its self-adhesive roller 905 contacts the top surface of the aluminum substrate, so that the self-adhesive roller 905 moves vertically along the vertical rod 902 under the action of the movable shaft 903 to compress the second spring 904. The second spring 904 is sleeved on the surface of the vertical rod 902, and its two ends are respectively fixed to the bottom surface of the protrusion 901 and the surface of the movable shaft 903, providing a downward elastic force for the movable shaft 903, so that the self-adhesive roller 905 can be in close contact with the surface of the aluminum substrate under the action of the elastic force. When the aluminum substrate is being conveyed, the self-adhesive roller 905 rolls on the surface of the aluminum substrate, and uses its own viscosity to absorb dust and tiny impurities remaining on the surface of the aluminum substrate, thereby achieving secondary cleaning of the aluminum substrate.

[0032] In some practical applications, the centering component 10 includes a step rod 1001 which is vertically movably plugged into the top surface of the protective cover 8, and a centering limit plate 1003 is fixedly installed at the bottom end of the step rod 1001. A third spring 1002 is sleeved on the surface of the step rod 1001, and the two ends of the third spring 1002 are respectively fixed to the top surface of the protective cover 8 and the end surface of the step rod 1001. A through groove 1004 is provided on the surface of the centering limit plate 1003, and a roller 1005 is rotatably fixedly installed on one side wall of the centering limit plate 1003.

[0033] More specifically, during the conveying process of the aluminum substrate, the aluminum substrate is centered by two groups of symmetrically arranged centering limit plates 1003, and the roller 1005 contacts the top surface of the aluminum part, so that the roller 1005 rolls along the top surface at the edge of the aluminum substrate. After the aluminum substrate contacts the roller 1005, the centering limit plate 1003 and the step rod 1001 are lifted and the third spring 1002 is stretched, so that the glue cleaning component 11 can fit the edge top surface of the aluminum substrate and can be adapted to the glue coating of aluminum substrates of different thicknesses.

[0034] In some practical applications, the glue cleaning component 11 includes a scraper plate 1101 fixedly installed inside the through groove 1004, a first slope 1102 is provided at the end of the scraper plate 1101, and a glue discharge port 1103 is provided at the inner bottom of the scraper plate 1101, a glue discharge port 1104 is provided on the surface of the scraper plate 1101, a connecting pipe 1105 is fixedly connected to the end of the glue discharge port 1104, a micro liquid pump 1106 is fixedly installed on the other side wall of the center limiting plate 1003, an end of the connecting pipe 1105 is connected to the input end of the micro liquid pump 1106, an output end of the micro liquid pump 1106 is connected to a glue discharge pipe 1107, and an end of the glue discharge pipe 1107 passes through the protective cover 8 and extends to the outside thereof.

[0035] More specifically, when the glue is conveyed to the aluminum substrate, the bottom surface of the scraper 1101 and the top surface of the edge of the aluminum substrate slide in contact with each other. The scraper 1101 scrapes the excess glue on the edge surface of the aluminum substrate to the inside of the scraper 1101 through the guiding effect of the first slope 1102 and the second slope 1103. The scraped glue is discharged through the glue discharge port 1104. The micro liquid pump 1106 is installed on the connecting pipe 1105 to provide power for the recovery of the glue, and the excess glue is conveyed to the recovery device or processing system outside the equipment through the glue discharge pipe 1107, which can effectively avoid the accumulation of glue at the edge of the aluminum substrate and reduce the amount of glue flowing to the edge of the aluminum substrate.

[0036] In some practical applications, the quantitative glue coating assembly 12 includes two groups of electric push rods 1201 fixedly installed on the inner top of the protective cover 8, a glue coating head 1202 is fixedly installed on the end of the electric push rod 1201, a glue box 1203 is fixedly installed on the top surface of the protective cover 8, the output end of the glue box 1203 is fixedly connected to a high-precision metering pump 1204, and the output end of the high-precision metering pump 1204 is fixedly connected to a glue supply pipe 1205, the glue supply pipe 1205 passes through the top of the protective cover 8 and is connected to the input end of the glue coating head 1202, wherein the glue supply pipe 1205 adopts a corrugated pipe.

[0037] More specifically, during the gluing process, the glue liquid in the glue box 1203 is precisely controlled by the high-precision metering pump 1204 and quantitatively delivered to the glue coating head 1202 through the glue supply pipe 1205. The electric push rod 1201 drives the glue coating head 1202 to move vertically and accurately spray a quantitative amount of glue liquid evenly on the surface of the aluminum substrate.

[0038] In some practical applications, one end of the center limit plate 1003 is an arc-shaped structure, and the other end is a straight structure, and the scraper plate 1101 and the roller 1005 are both located in the straight portion of the center limit plate 1003, and the bottom surface of the scraper plate 1101 is flush with the bottom end of the roller 1005.

[0039] More specifically, when the centering limit plate 1003 contacts the side of the aluminum substrate, the arc-shaped end can smoothly guide the aluminum substrate into centering adjustment, reducing obstruction and impact on the forward direction of the aluminum substrate. The scraper plate 1101 and the roller 1005 are both located on the straight part of the centering limit plate 1003 and are flush with each other, so that the scraper plate 1101 can maintain good contact with the surface at the edge of the aluminum substrate, thereby achieving effective scraping through the scraper plate 1101.

[0040] In some practical applications, the glue coating head 1202 is located between two sets of center limiting plates 1003 , and the glue coating head 1202 is located between the roller 1005 and the scraper plate 1101 .

[0041] More specifically, the glue coating head 1202 is located between the two groups of center limiting plates 1003, so that the glue coating head 1202 can accurately align with the central area of ​​the aluminum substrate for glue coating operations, creating good conditions for the precise glue coating of the glue coating head 1202, and the glue coating head 1202 is between the roller 1005 and the scraper plate 1101, so the aluminum substrate is guided and cleaned respectively by the roller 1005 and the scraper plate 1101.

[0042] In summary: the servo moving component 3 drives the pick-up frame 4 and the vacuum suction cup 6 on its surface to move, so as to realize the picking up and conveying of the aluminum substrate to the surface of the conveying mechanism 2. While picking up and conveying the stacked aluminum substrates, the blowing component 5 makes the airflow blow toward the top surface of the aluminum substrate to preliminarily remove the dust and impurities on the surface of the aluminum substrate. At the same time, the first spring 7 realizes the elastic connection between the vacuum suction cup 6 and the pick-up frame 4. The impact of the airflow can also cause the aluminum substrate to generate low-frequency vibration, so as to avoid the stacked aluminum substrates from sticking to each other and being difficult to separate when picking up the aluminum substrates, and ensure that each picked up aluminum substrate is a single piece, and is conveyed. The mechanism 2 is used to transport the aluminum substrate. Before the aluminum substrate enters the interior of the protective cover 8, its dust cleaning component 9 contacts the surface of the aluminum substrate to clean the dust and impurities on the surface of the aluminum substrate again, thereby improving the cleanliness of the aluminum substrate. Through the two groups of symmetrically arranged centering components 10, it is ensured that the aluminum substrate is always in the center position during the transportation and gluing process, and the quantitative gluing component 12 can be used to spray glue on its surface to avoid uneven glue coating or glue coating failure due to position offset. The glue cleaning component 11 on the surface of the centering component 10 cleans the excess glue that flows to the edge of the aluminum substrate during the gluing process, thereby reducing the flow of excessive glue to the edge of the aluminum substrate.
