Description

Technical Field

[0001] The present invention relates to the technical field of inductor production, and in particular to a packaging device for inductor production. Background Art

[0002] When an inductor is packaged, glue is mainly applied to the wafer through a dispensing mechanism. Currently, a dispensing tube is often used for dispensing operations, and the inductor is dispensed in a production line form to achieve sealing.

[0003] However, the existing dispensing method has certain drawbacks. Since the dispensing tube discharges the insulating glue in the tube through air pressure, some residual glue will remain in the dispensing tube during the process of discharging the glue. And the dispensing port of the dispensing tube is in an open state, which will cause the residual insulating glue in the dispensing tube to drip onto the workbench. Later, the glue on the workbench needs to be cleaned separately, and the operation is rather troublesome.

[0004] Therefore, we propose a packaging device for inductor production to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a packaging device for inductor production to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A packaging device for inductor production includes a dispensing head. The dispensing head includes a glue storage cavity, a metering cavity, and a pressure regulating cavity that are connected in sequence. An air pump for regulating the air pressure in the pressure regulating cavity is connected to the pressure regulating cavity. A piston rod is slidably installed in the pressure regulating cavity. The rod of the piston rod extends into the metering cavity and is in sliding contact with the inner wall of the metering cavity. A dispensing tube is connected to the bottom of the metering cavity, and check valves are installed in the channels between the dispensing tube and the metering cavity and between the metering cavity and the glue storage cavity to control the glue to flow only from the glue storage cavity to the metering cavity and then to the dispensing tube;

[0008] A protective ring concentric with the dispensing tube is movably sleeved outside the dispensing tube. A vertical telescopic member I is installed at the outer edge of the protective ring to control the vertical lifting movement of the protective ring along the dispensing tube. A tray is covered outside the bottom port of the protective ring, and one corner of the outer side of the tray is rotatably connected to one corner of the outer side of the protective ring through a rotating shaft, and a motor I is also connected to the rotating shaft.

[0009] In a further embodiment, a telescopic sleeve is connected between the protective ring and the bottom of the metering cavity. The telescopic sleeve is sleeved outside the dispensing tube, and the telescopic sleeve adopts a tower-shaped structure that is narrower at the top and wider at the bottom.

[0010] In a further embodiment, a vertical scraper is installed inside the telescopic sleeve through a second telescopic member, and the telescopic direction of the second telescopic member is parallel to the radial direction of the dispensing tube. A toothed ring is fixed under the second telescopic member, and the toothed ring is rotatably connected to the upper surface of the protective ring concentrically. A gear meshing with the toothed ring is also rotatably installed on the upper surface of the protective ring, and a second motor is connected to the gear.

[0011] In a further embodiment, an air duct is also provided inside the outer shell of the metering chamber. One end of the air duct penetrates the bottom surface of the metering chamber and is connected to the inside of the telescopic sleeve, and the other end of the air duct penetrates the side surface of the metering chamber and is connected to an air pipe.

[0012] In a further embodiment, a cleaning cover is installed outside the telescopic sleeve through a bracket. The bottom surface of the cleaning cover is flush with the upper surface of the support plate. After the support plate under the protective ring is rotated 180°, it covers the lower part of the cleaning cover. A horizontal scraper is rotatably installed inside the cleaning cover, and a third motor is installed on the cleaning cover.

[0013] In a further embodiment, the cleaning cover is connected to the inside of the air pipe through a flexible hose.

[0014] In a further embodiment, an annular curing lamp is installed on the outer edge of the lower port of the protective ring.

[0015] In a further embodiment, an annular heating pipe is installed on the inner wall of the inner ring of the protective ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By providing a protective ring outside the dispensing tube, the present invention can cover the lower port of the dispensing tube when the dispensing tube is on standby, isolate the dispensing tube from the workbench by using the support plate, effectively prevent the residual glue in the dispensing tube from dripping on the tabletop, and at the same time, the support plate can be rotated and opened relative to the protective ring, facilitating the vertical lifting of the protective ring along the dispensing tube. The protective ring can be stored above when the dispensing tube is working, without affecting the normal dispensing operation of the dispensing tube.

[0018] The present invention is also equipped with a glue scraping structure composed of a second telescopic member, a vertical scraper, a toothed ring, a gear and a second motor in the protective ring, which can clean the residual glue around the dispensing port of the dispensing tube, thus ensuring the smoothness of the glue flowing out of the dispensing port and reducing the blockage problem caused by the curing of the residual glue.

[0019] The present invention is provided with a foreign matter removing structure composed of a cleaning cover, a horizontal scraper and a third motor, which can clean and scrape the colloid on the surface of the support plate when the support plate is not in the closed state, thus ensuring the cleanliness of the support plate.

[0020] The present invention also provides a suction pipeline structure composed of an air duct, an air pipe and a hose, which can suck and remove the residual glue cleaned out from the protective ring and the cleaning cover.

[0021] The present invention also provides a curing lamp and a heating pipe. When the dispensing head is on standby, the curing lamp can cure and irradiate the glue at the dispensing port of the dispensing pipe to prevent it from dripping. When the dispensing head resumes work, during the lifting and moving process of the protective ring, the heating pipe can heat the whole dispensing pipe to accelerate the melting of the glue, which is convenient for re - engaging in the dispensing operation process, effectively reducing the waste of the glue.

In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-6 , a packaging device for inductor production, including a dispensing head. The dispensing head includes a glue storage cavity 1, a metering cavity 2, and a pressure regulating cavity 3 that are connected in sequence. Among them, the glue storage cavity 1 is connected to the metering cavity 2 horizontally upward, and the pressure regulating cavity 3 is connected to the metering cavity 2 vertically upward. An air pump 4 for adjusting the air pressure in the pressure regulating cavity 3 is connected to the pressure regulating cavity 3. A piston rod 5 is slidably installed in the pressure regulating cavity 3. The rod of the piston rod 5 extends into the metering cavity 2 and slides closely against the inner wall of the metering cavity 2. A dispensing tube 6 is connected to the lower part of the metering cavity 2. One-way valves 7 are installed in the channels between the dispensing tube 6 and the metering cavity 2 and between the metering cavity 2 and the glue storage cavity 1. The one-way valves 7 are used to control that the glue can only flow from the glue storage cavity 1 to the metering cavity 2 and then to the dispensing tube 6. When the air pressure inside the pressure regulating cavity 3 decreases, the piston rod 5 retracts upward. At this time, the glue in the glue storage cavity 1 can be pumped into the metering cavity 2. Since the channel between the metering cavity 2 and the glue storage cavity 1 is in a U-shaped structure, under the action of gravity, the glue in the glue storage cavity 1 will not flow into the metering cavity 2. When the piston rod 5 is pressed down, the glue in the metering cavity 2 can be completely extruded.

[0033] In order to protect the dispensing head from dripping glue during standby, a protective ring 9 concentric with the dispensing tube 6 is sleeved outside the dispensing tube 6. A first vertical telescopic member 8 is installed on the outer edge of the protective ring 9. The telescopic member 8 can be a cylinder or an electric push rod, which is used to drive the protective ring 9 to move up and down. When the protective ring 9 rises, it approaches the metering chamber 2 so as not to interfere with the use of the dispensing tube 6. After the protective ring 9 lowers its height, a support plate 10 covers the outer bottom port of the protective ring 9, thus separating the workbench from the dispensing tube 6. One outer corner of the support plate 10 is rotatably connected to one outer corner of the protective ring 9 through a rotating shaft. A first motor 11 is also connected to this rotating shaft, and the main body of the first motor 11 is fixedly connected to the protective ring 9, so as to drive the support plate 10 to rotate horizontally through the first motor 11, so as to cover the bottom port of the protective ring 9 or open the bottom port of the protective ring 9.

[0034] In order to further improve the protection effect, a telescopic sleeve 12 is connected between the protective ring 9 and the bottom of the metering chamber 2. The telescopic sleeve 12 is sleeved outside the dispensing tube 6, and the telescopic sleeve 12 adopts a tower-shaped structure that is narrower at the top and wider at the bottom, so as to completely enclose and protect the dispensing tube 6 during standby. Since the telescopic sleeve 12 adopts a tower-shaped structure, after the protective ring 9 rises, it can drive the telescopic sleeve 12 to retract and fold.

[0035] In order to reduce the dripping of glue, a ring-shaped curing lamp 13 is installed on the outer edge of the lower port of the protective ring 9, so as to irradiate the dispensing port with the ring-shaped curing lamp 13 turned on during standby, so that the glue at its port is cured, thereby preventing the glue from continuing to drip. Further, a ring-shaped heating tube 14 is installed on the inner wall of the inner ring of the protective ring 9, so as to heat the dispensing port with the ring-shaped heating tube 14 turned on when the dispensing head continues to work, accelerating the melting of its glue. At the same time, during the lifting and moving process of the protective ring 9, the heating tube 14 can heat the entire body of the dispensing tube 6, thereby accelerating the melting of the glue and facilitating the resumption of the dispensing operation process, effectively reducing the waste of glue.

[0036] Considering that after the glue overflows from the dispensing port and solidifies around the dispensing tube 6, affecting the subsequent glue application effect, a vertical scraper 16 is installed inside the telescopic sleeve 12 through a second telescopic member 15, and the telescopic direction of the second telescopic member 15 is parallel to the radial direction of the dispensing tube 6, so as to drive the vertical scraper 16 to closely adhere to the periphery of the dispensing tube 6. A toothed ring 17 is fixed under the second telescopic member 15, and the toothed ring 17 is rotatably connected to the upper surface of the protective ring 9 concentrically. A gear 18 meshing with the toothed ring 17 is also rotatably installed on the upper surface of the protective ring 9, and a second motor 19 is connected to the gear 18. The main body of the second motor 19 is fixedly installed on the protective ring 9. The second motor 19 drives the gear 18 to rotate, and the gear 18 drives the toothed ring 17 to rotate, which can drive the second telescopic member 15 and the vertical scraper 16 to rotate circumferentially, so as to rotate and scrape the solidified glue on the dispensing tube 6.

[0037] In order to facilitate the cleaning of the scraped glue chips, an air duct 20 is further provided inside the housing of the metering chamber 2. One end of the air duct 20 penetrates the bottom surface of the metering chamber 2 and is connected to the inside of the telescopic sleeve 12. The other end of the air duct 20 penetrates the side surface of the metering chamber 2 and is connected with an air duct 21. The air duct 21 is externally connected to a suction device, so that the glue chips in the protective ring 9 and the telescopic sleeve 12 can be sucked away.

[0038] Considering that glue liquid may drip onto the pallet 10 and protrude from the pallet 10 after curing, which will affect the horizontal opening and closing of the pallet 10. To ensure the normal use of the pallet 10, a cleaning cover 22 is installed on the outside of the telescopic sleeve 12 through a bracket. The bottom surface of the cleaning cover 22 is flush with the upper surface of the pallet 10. When the pallet 10 under the protective ring 9 rotates 180°, it just covers the lower part of the cleaning cover 22. A horizontal scraper 23 is rotatably installed in the cleaning cover 22. The horizontal scraper 23 is closely attached to the upper surface of the pallet 10. A motor three 24 is installed on the cleaning cover 22. The output shaft of the motor three 24 is connected to the horizontal scraper 23, so as to drive the horizontal scraper 23 to rotate on the surface of the pallet 10 to scrape off the cured glue liquid, thus ensuring the flatness of the surface of the pallet 10. At the same time, the cleaning cover 22 is connected to the inside of the air duct 21 through a hose 25, so that the air duct 21 can suck out the scraped glue chips through the hose 25.
