Abstract
Description
Technical Field
[0001] This utility model relates to the field of COB surface light source packaging technology, specifically to an automated COB surface light source packaging device. Background Technology
[0002] With the rapid development of lighting, display and other fields, the market demand for LED light sources is constantly increasing, especially for high-performance, cost-effective COB surface light sources. In order to meet the needs of large-scale production, it is necessary to develop automated packaging equipment to improve production efficiency, reduce costs and ensure product quality.
[0003] However, during the potting of COB chips, uneven mixing of the adhesive or unsuitable environmental conditions such as humidity and temperature may cause air to be trapped in the adhesive during the potting or curing process, forming air bubbles. This can reduce the heat dissipation performance and mechanical strength of the package, and may also affect the propagation of light. To address this, we propose an automated packaging device for COB surface light sources. Utility Model Content
[0004] The purpose of this invention is to provide an automated packaging device for COB surface light sources, in order to solve the problem mentioned in the background art that, when potting COB chips, uneven mixing of the adhesive or unsuitable environmental humidity, temperature, and other conditions may cause air to be easily trapped in the adhesive during the potting or curing process, forming air bubbles, which in turn reduces the heat dissipation performance and mechanical strength of the package, and may also affect the propagation of light.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated packaging device for COB surface light sources, including a carrier frame, a packaging box fixedly installed on the top surface of the carrier frame, a vibration component provided at the bottom of the carrier frame, a clamping and fixing component provided at the top of the carrier frame, a conveyor belt provided inside the carrier frame, and two clamping and fixing components symmetrically arranged around the longitudinal central axis of the carrier frame.
[0006] The vibration assembly includes a spring, which is fixedly installed at the bottom of the support frame. A mounting base is fixedly installed at the bottom of the spring. A buffer rod is fixedly installed at the bottom of the support frame. Buffer cotton is provided at the bottom of the buffer rod. A buffer rod is provided inside the spring. The buffer rod is slidably connected to the mounting base through a through hole provided inside the mounting base.
[0007] The mounting base has a motor fixedly installed inside, a limit rod fixedly installed on the top of the motor, two limit discs fixedly installed on the outside of the limit rod, a reciprocating screw fixedly installed at one end of the motor's output shaft, a telescopic rod fixedly installed inside the reciprocating screw, a telescopic rod rotatably connected to the bottom of the support frame, and a movable frame threadedly connected to the outside of the reciprocating screw.
[0008] The movable frame is slidably connected to the movable frame through a sliding hole provided inside it. The movable frame is located between two limiting plates. Both limiting plates are rotatably connected to a reciprocating screw. A piston is provided inside the buffer rod. Multiple push rods are fixedly installed on the top of the movable frame.
[0009] The clamping and fixing assembly includes a first electric push rod, which is fixedly installed on one side of the packaging box. A fixing frame is fixedly installed on the top of the support frame. The output end of the first electric push rod passes through the fixing frame, and a clamping frame is fixedly installed on the output end of the first electric push rod.
[0010] The clamping frame has a protective pad fixedly installed on one side, a second electric push rod fixedly installed on the top of the clamping frame, a limit frame fixedly installed at the output end of the second electric push rod, and multiple rubber pads provided at the bottom of the limit frame.
[0011] This utility model has at least the following beneficial effects:
[0012] The continuous and stable vibration of the vibration component effectively promotes the removal of a large number of air bubbles in the adhesive solution inside the encapsulation box after potting, greatly reducing the residual amount of air bubbles in the final encapsulated product. This helps improve the light emission uniformity of the COB surface light source, reduce abnormal light refraction and scattering caused by the presence of air bubbles, and enhance the optical performance of the product. The clamping and fixing component firmly fixes the product, allowing the vibration generated by the vibration component to be transmitted to the adhesive solution more efficiently, enhancing the effect of air bubbles overcoming the resistance of the adhesive solution and being discharged upwards. Compared with when the product is not firmly fixed, the air bubbles are discharged more thoroughly, further reducing the residual amount of air bubbles in the encapsulated product.

[0018] 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.
[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an automated packaging equipment for COB surface light source, including a carrier frame 3, a packaging box 1 fixedly installed on the top surface of the carrier frame 3, a vibration component 4 provided at the bottom of the carrier frame 3, a clamping and fixing component 2 provided at the top of the carrier frame 3, a conveyor belt 5 provided inside the carrier frame 3, and two clamping and fixing components 2 symmetrically arranged through the longitudinal central axis of symmetry of the carrier frame 3.
[0020] The vibration assembly 4 includes a spring 49, which is fixedly installed at the bottom of the support frame 3. A mounting base 41 is fixedly installed at the bottom of the spring 49. A buffer rod 410 is fixedly installed at the bottom of the support frame 3, and buffer cotton is provided at the bottom of the buffer rod 410. The buffer rod 410 is located inside the spring 49. The mounting base 41 is slidably connected to the buffer rod 410 through a through hole inside it. A motor 42 is fixedly installed inside the mounting base 41. A limit rod 43 is fixedly installed at the top of the motor 42. Two limit discs 46 are fixedly installed on the outside of the limit rod 43. A reciprocating screw 48 is fixedly installed at one end of the output shaft of the motor 42. A telescopic rod 47 is fixedly installed inside the reciprocating screw 48. The bottom of the support frame 3... A telescopic rod 47 is rotatably connected, and a movable frame 44 is externally threaded to a reciprocating screw 48. The movable frame 44 is slidably connected through a sliding hole inside it. The movable frame 44 is located between two limiting plates 46. The reciprocating screw 48 is rotatably connected inside both limiting plates 46. A piston 411 is installed inside a buffer rod 410. Multiple push rods 45 are fixedly installed on the top of the movable frame 44. During the up and down movement of the push rods 45, they drive the support frame 3 and the encapsulation box 1 on it to vibrate. When the equipment completes the dispensing, the air bubbles in the adhesive in the encapsulation box 1 are affected by the vibration. The vibration causes a small flow and disturbance inside the adhesive. Under this action, the air bubbles are more likely to overcome the surface tension and viscous resistance of the adhesive.
[0021] The clamping and fixing assembly 2 includes a first electric push rod 21, which is fixedly installed on one side of the packaging box 1. A fixing frame 22 is fixedly installed on the top of the support frame 3. The output end of the first electric push rod 21 passes through the fixing frame 22. A clamping frame 23 is fixedly installed on the output end of the first electric push rod 21. A protective pad 26 is fixedly installed on one side of the clamping frame 23. A second electric push rod 24 is fixedly installed on the top of the clamping frame 23. A limit frame 25 is fixedly installed on the output end of the second electric push rod 24. Multiple rubber pads are provided at the bottom of the limit frame 25. After the product is fixed, the vibration assembly 4 at the bottom of the support frame 3 starts to work. The product is stably fixed. Under the vibration generated by the vibration assembly 4, the adhesive in the packaging box 1 is affected by the vibration. Since the product is firmly clamped, the vibration can be transmitted to the adhesive more effectively, causing a small flow and disturbance inside the adhesive.
[0022] First, the COB chip is placed on conveyor belt 5. Then, conveyor belt 5 is started to gradually transport the COB chip into the packaging box 1 and ensure that the COB chip is completely within the clamping area of the clamping and fixing component 2. Then, two first electric push rods 21 are simultaneously activated to move the two clamping frames 23 and clamp and fix the COB chip. The protective pad 26 is provided to protect the COB chip during clamping. Next, the potting mechanism inside the packaging box 1 begins to evenly fill the chip and substrate with encapsulating adhesive to form a protective coating. To prevent air bubbles from forming after potting due to uneven adhesive mixing or unsuitable environmental humidity or temperature conditions, the second electric push rod 24 is activated to move the limiting frame 25 downwards and limit and fix the COB chip. Then, motor 42 is started to rapidly rotate the reciprocating screw 48, causing the moving frame 44 to rapidly move upwards. As the moving frame 44 moves to the other end of the reciprocating screw 48, the push rod 45 also moves and lifts the support frame 3 a short distance. At this time, the spring 49 and the telescopic rod 47 are stretched. Then, as the moving frame 44 moves quickly downward, the push rod 45 also moves quickly downward, and the support frame 3 moves quickly downward. Due to the setting of the spring 49 and its own elasticity, the support frame 3 vibrates, which causes the COB chip to vibrate. The vibration can intensify the molecular movement inside the glue, reduce the surface tension of the bubbles, and promote the expulsion of the bubbles. The buffer rod 410 and the piston 411 inside it are to prevent the support frame 3 from vibrating too violently and damaging the COB chip. After the glue cures, the motor 42 is turned off and the conveyor belt 5 is started to send the damaged COB chip out of the packaging box 1.
