Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a surface-mount LED packaging structure. Background Technology

[0002] Surface mount LEDs are miniaturized, surface-mount light-emitting diodes widely used in lighting, displays, backlighting, and other fields. Compared with traditional through-hole LEDs, they have advantages such as small size, low power consumption, good heat dissipation, and suitability for automated production. The main structure consists of a chip for emitting light, a metal substrate that supports the chip, and electrodes that connect the chip and the metal substrate. In addition, after the LED is assembled, it needs to be protected with encapsulating adhesive. Most existing LED surface mount adhesive dispensing and encapsulation equipment requires manual application of encapsulating adhesive, which requires stopping the equipment. This results in high labor intensity and frequent downtime, which also affects production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a surface-mount LED packaging structure that can automatically add encapsulating adhesive without stopping production, thereby reducing labor intensity and improving production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface mount LED packaging structure, including a base, a main equipment unit, a conveyor belt and a fixing frame on the base, a moving part inside the main equipment unit, a glue dispenser on the moving part, multiple glue dispensing heads below the glue dispenser, a glue dispensing tank on the glue dispenser, an air pipe connected to the main equipment unit on the top of the glue dispensing tank, a glue storage component on the fixing frame, and a glue replenishing pipe connected to the side of the glue dispensing tank below the glue storage component; A one-way valve is provided between the dispensing can and the dispensing device.

[0005] Preferably, the glue storage component includes a glue storage tank mounted on a fixed frame, the glue storage tank is provided with a cover plate, the side of the cover plate is provided with an eye bolt for connecting to the glue storage tank, and the cover plate is provided with a one-way air inlet valve.

[0006] Preferably, the storage tank has a hollow cavity inside its wall, a spiral baffle is provided inside the hollow cavity, and a cold air inlet and a cold air outlet communicating with the hollow cavity are provided on the side of the storage tank.

[0007] Preferably, the dispensing can includes a transparent can body connected to a one-way valve, the top of the transparent can body is provided with an internally threaded can cover connected to an air pipe, and the side of the transparent can body is provided with a filling port connected to a filling tube.

[0008] Preferably, the one-way valve includes a first valve body connected to the dispensing can and a second valve body connected to the dispensing device, wherein an internal hex bolt is connected between the first valve body and the second valve body; The second valve body has a groove, and a one-way valve is provided in the groove. The one-way valve is in the shape of a downward cone.

[0009] Preferably, the moving component includes a horizontal moving assembly disposed within the main unit of the device, a first connecting frame disposed below the horizontal moving assembly, a vertical moving assembly disposed on the side of the first connecting frame, and a second connecting frame disposed on the front of the vertical moving assembly for connection with the dispensing device.

[0010] Preferably, the horizontal moving component includes a horizontal slide rail disposed inside the main unit of the equipment, a horizontal lead screw rotatably disposed inside the horizontal slide rail, a horizontal motor disposed on the end face of the horizontal lead screw, and a horizontal sleeve fixed to the first connecting frame fitted on the horizontal lead screw.

[0011] Preferably, the vertical moving assembly includes a vertical slide rail connected to the first connecting frame, a vertical lead screw rotatably disposed within the vertical slide rail, a vertical motor disposed on the end face of the vertical lead screw, and a vertical sleeve fixed to the second connecting frame fitted on the vertical lead screw.

[0012] Compared with the prior art, the present invention provides a surface-mount LED packaging structure, which has the following advantages: 1. By setting up a glue storage component and a one-way valve, the glue storage component is connected to the glue dispensing tank via a glue replenishment tube. When the encapsulating glue in the glue dispensing tank decreases to a critical value, the air pipe changes from supplying air to the glue dispensing tank to extracting air during the loading and unloading time of the LED chips, creating a negative pressure in the glue dispensing tank. Since the connection between the glue dispenser and the glue dispensing tank is closed by the one-way valve, the negative pressure in the glue dispensing tank will draw the encapsulating glue from the glue storage component through the glue replenishment tube, so that the encapsulating glue is automatically replenished into the glue dispensing tank, achieving the purpose of glue replenishment without stopping the machine, reducing labor intensity and improving production efficiency.

[0013] 2. By setting up a hollow cavity and a spiral baffle, the hollow cavity is opened inside the wall of the glue storage tank, forming an inner and outer liner. During operation, cold air can circulate in the hollow cavity through the cold air inlet and outlet, maintaining a suitable low-temperature environment for the encapsulating glue inside the storage tank. This avoids the problem of the encapsulating glue solidifying due to excessively high external temperatures, allowing for the preparation of large quantities of encapsulating glue at once and reducing the frequency of encapsulating glue preparation. The spiral baffle is spirally set in the hollow cavity, so that when cold air circulates, it flows around the hollow cavity along the spiral baffle, ensuring that all parts of the air cavity maintain a consistent temperature and guaranteeing temperature uniformity.

[0016] 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.

[0017] Please see Figure 1-5 A surface mount LED packaging structure includes a base (1), a main unit (2), a conveyor belt (3) and a fixing frame (10) on the base (1), a moving part (4) inside the main unit (2), a glue dispenser (11) on the moving part (4), a plurality of glue dispensing heads (12) below the glue dispenser (11), a glue dispensing tank (6) on the glue dispenser (11), an air pipe (5) connected to the main unit (2) on the top of the glue dispensing tank (6), a glue storage component (8) on the fixing frame (10), and a glue replenishing pipe (7) connected to the side of the glue dispensing tank (6) below the glue storage component (8). By setting up a glue storage component (8) and a one-way valve (9), the glue storage component (8) is connected to the glue dispensing tank (6) via a glue replenishing pipe (7). When the encapsulating glue in the glue dispensing tank (6) is reduced to a critical value, the air pipe (5) is changed from supplying air to the glue dispensing tank (6) to extracting air during the loading and unloading time of the LED patch, so that a negative pressure is generated in the glue dispensing tank (6). Since the connection between the glue distributor (11) and the glue dispensing tank (6) is closed by the one-way valve (9), the negative pressure in the glue dispensing tank (6) will draw the encapsulating glue in the glue storage component (8) through the glue replenishing pipe (7), so that the encapsulating glue is automatically replenished into the glue dispensing tank (6), achieving the purpose of glue replenishment without stopping the machine, reducing labor intensity and improving production efficiency. In addition, a one-way valve (9) can be installed between the glue supply tube (7) and the glue storage tank (801) to prevent air from escaping into the glue storage tank (801) when the glue dispensing tank (6) uses positive pressure air to deliver the encapsulating glue into the glue dispenser (11).

[0018] The glue storage component (8) includes a glue storage tank (801) mounted on a fixed frame (10), a cover plate (806) on the glue storage tank (801), a ring bolt (807) connected to the glue storage tank (801) on the side of the cover plate (806), and a one-way air inlet valve (808) on the cover plate (806). By setting a one-way air inlet valve (808), air can be allowed to enter the glue storage tank (801), so that when the glue in the glue storage tank (801) is reduced, air can be automatically replenished to achieve air pressure balance, avoiding the problem of negative pressure in the glue storage tank (801) causing the glue to be unable to flow out. In addition, the natural air replenished into the glue storage tank (801) can be replaced with inert air to reduce the problem of glue oxidation.

[0019] The storage tank (801) has a hollow cavity (802) inside its wall, and a spiral baffle (803) is provided inside the hollow cavity (802). The side of the storage tank (801) is provided with a cold air inlet (804) and a cold air outlet (805) that communicate with the hollow cavity (802). By setting a hollow cavity (802) and a spiral baffle (803), the hollow cavity (802) is opened inside the wall of the glue storage tank (801), so that the glue storage tank (801) forms an inner liner and an outer liner. During operation, cold air can circulate in the hollow cavity (802) through the cold air inlet (804) and the cold air outlet (805), so that the glue storage tank (801) maintains a low temperature environment suitable for the encapsulating glue, avoiding the problem of the encapsulating glue solidifying due to excessively high external temperature, so that a large amount of encapsulating glue can be prepared at one time, reducing the working frequency of encapsulating glue preparation. The spiral baffle (803) is spirally set in the hollow cavity (802), so that when the cold air circulates, it will flow around the hollow cavity (802) along the spiral baffle (803), so that the temperature of each part in the air cavity can be kept consistent, ensuring the uniformity of constant temperature.

[0020] The dispensing can (6) includes a transparent can body (601) connected to a one-way valve (9), the top of the transparent can body (601) is provided with an internally threaded can cover (602) connected to the air pipe (5), and the side of the transparent can body (601) is provided with a glue filling port (603) connected to the glue filling pipe (7). By setting an internal threaded can cover (602), the internal threaded can cover (602) is detachably connected to the transparent can body (601) by means of threads, which makes it easy to clean the inside of the dispensing can (6) after the equipment is used, and prevents the encapsulating glue from staying in the dispensing can (6) for a long time, causing pollution and blockage.

[0021] A one-way valve (9) is provided between the dispensing can (6) and the dispensing device (11). The one-way valve (9) includes a first valve body (901) connected to the dispensing can (6) and a second valve body (903) connected to the dispensing device (11). An internal hex bolt (902) is connected between the first valve body (901) and the second valve body (903). A groove (904) is provided on the second valve body (903). A one-way valve piece (905) is provided in the groove (904). The one-way valve piece (905) is in the shape of a downward cone. By setting a one-way valve piece (905), the one-way valve piece (905) is located in the groove (904) and is clamped between the first valve body (901) and the second valve body (903). At the same time, the thickness of the one-way valve piece (905) is higher than that of the groove (904), so that it will deform when it is clamped, thereby sealing the gap between the first valve body (901) and the second valve body (903). The one-way valve piece (905) is mainly composed of multiple valves, and these valves are normally conical. When the encapsulating glue is input from the dispensing can (6), it will push the valves outward, so that the encapsulating glue can flow out smoothly. When the encapsulating glue is input from the dispensing device (11), it will push the valves towards the center, so that the multiple valves are squeezed against each other and cannot unfold, thereby achieving the purpose of one-way delivery and greatly reducing the obstruction to the encapsulating glue. The first valve body (901) and the second valve body (903) are detachably connected by hexagonal socket head cap screws (902), allowing the one-way valve plate (905) to be removed during maintenance for easy cleaning and to prevent clogging.

[0022] The moving part (4) includes a horizontal moving component (401) disposed in the main unit (2) of the equipment, a first connecting frame (402) is provided under the horizontal moving component (401), a vertical moving component (403) is provided on the side of the first connecting frame (402), and a second connecting frame (404) connected to the glue separator (11) is provided on the front of the vertical moving component (403). By setting up a horizontal moving component (401) and a vertical moving component (403), the vertical moving component (403) can drive the glue dispenser (11) and the glue dispensing head (12) to move up and down, thereby realizing the motion work of dispensing. The horizontal moving component can drive the glue dispenser (11) and the glue dispensing head (12) to move horizontally through the vertical moving component (403), thereby realizing the purpose of dispensing LED chips at different positions. In addition, it can be combined with the movement of the conveyor belt (3) to enable the equipment to achieve the effect of three-axis movement.

[0023] The horizontal moving assembly (401) includes a horizontal slide rail (4011) disposed inside the main unit (2) of the equipment, a horizontal lead screw (4012) rotatably disposed inside the horizontal slide rail (4011), a horizontal motor (4014) disposed on the end face of the horizontal lead screw (4012), and a horizontal sleeve (4013) fixed to the first connecting frame (402) fitted on the horizontal lead screw (4012). The vertical moving assembly (403) includes a vertical slide rail (4031) connected to the first connecting frame (402), a vertical lead screw (4032) rotatably disposed inside the vertical slide rail (4031), a vertical motor (4034) disposed on the end face of the vertical lead screw (4032), and a vertical sleeve (4033) fixed to the second connecting frame (404) fitted on the vertical lead screw (4032). By setting a horizontal lead screw (4012) and a vertical lead screw (4032), the horizontal lead screw (4012) and the vertical lead screw (4032) can use their own rotation to drive the corresponding horizontal lead sleeve (4013) and vertical lead sleeve (4033) to move linearly. The two cooperate with each other to achieve the purpose of moving along the Y-axis and Z-axis, and cooperate with the conveyor belt (3) to achieve the effect of moving along the X-axis. It can be applied to the LED chip dispensing and encapsulation work of most specifications.

[0024] It should also be noted that the main unit (2) is equipped with an air compressor that works with the air pipe (5) and a compressor that produces cold air, and has corresponding control equipment.

[0025] Working principle: During dispensing, the air pipe (5) delivers positive pressure air into the dispensing tank (6). The positive pressure air is used to squeeze the encapsulating adhesive out of the dispensing head (12). When the encapsulating adhesive in the dispensing tank (6) drops to the critical value, the air pipe (5) extracts the air from the dispensing tank (6) by taking advantage of the gap between the loading and unloading of the LED chip, so that a negative pressure is formed inside. Then, the encapsulating adhesive in the glue storage component (8) is extracted by the glue replenishing pipe (7), thus realizing automatic glue replenishment.

[0026] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
