Description

Technical Field

[0001] This invention relates to the field of LED substrate conveying technology, and in particular to an automatic loading and unloading mechanism for LED die bonders. Background Technology

[0002] An LED die bonder is an automated device used to precisely fix light-emitting diode (LED) chips onto a substrate. The substrate, as the carrier of the LED chip, not only needs to provide mechanical support but also needs to possess good electrical and thermal conductivity to ensure the efficient operation and long lifespan of the LED. However, existing LED die bonders still have some shortcomings in practical applications.

[0003] For example, Chinese patent CN113921434A discloses a high-efficiency automatic LED die bonding machine and die bonding method. Although this patent shortens the die bonding time and simplifies the mechanical structure by using a die bonding head, a dispensing head, and an adsorption rod, its design focuses on the die bonding process itself, with limited attention paid to the substrate conveying and unloading stages. Specific problems include:

[0004] 1. The lack of a positioning auxiliary mechanism when placing the PCB board body may cause positional deviations during direct transport, affecting die bonding quality and subsequent processes.

[0005] 2. After die bonding is completed, the PCB board body is unloaded again by the PCB board conveyor mechanism. The lack of an effective centralized collection method increases the management difficulty and is not conducive to large-scale production and automated assembly line operation.

[0006] To address this, an automatic loading and unloading mechanism for LED die bonder substrates was specially designed to overcome the shortcomings of existing technologies. Summary of the Invention

[0014] Optionally, it also includes electric push rods, inclined blocks, pressure strips, mating blocks, and springs. Symmetrical and facing electric push rods are installed on the top of the fixed and movable seats of the two brackets on the dual-axis linear module. An inclined block is provided on the telescopic end of the electric push rod. A pressure strip is embedded and slidably arranged in the upper part of both brackets. The pressure strip is close to the synchronous belt of the lower pulley assembly two. A mating block that abuts against the inclined block is provided at the center of the top of the pressure strip. Several springs are symmetrically arranged between the pressure strip and the corresponding fixed or movable seat.

[0015] Optionally, it also includes an appearance inspection device and a thermosetting device. The appearance inspection device is installed between the rear tops of the two brackets on the single-axis linear module, and the thermosetting device is installed between the front tops.

[0016] Optionally, the lifting assembly includes a reinforcing base, a second motor, a lead screw, a guide frame, and a slide. The reinforcing base is symmetrically arranged at the bottom of the mobile cabinet, and the reinforcing base is arranged corresponding to the three push ports. The second motor is installed on the side of the reinforcing base. A vertical lead screw is rotatably arranged in the middle of the top of the reinforcing base. The lead screw is connected to the output shaft of the second motor. A guide frame is arranged on the outer periphery of the top of the reinforcing base.

[0018] The beneficial effects are as follows: 1. The present invention allows the movable seat on the plate feeding assembly to be adjusted according to the width of the substrate body, and the position of the guide screw to be changed by rotating the torsion plate, so that the first and second pulley sets can adapt to substrate bodies of different widths; the large electric cylinder pushes the clamping plate, and the position of the clamping plate is adjusted according to the actual width of the substrate body to ensure that the substrate does not shift when it is conveyed in the placement frame.

[0019] 2. The present invention ensures that the substrate body is stably brought from the placement frame to the synchronous belt of the second pulley group by the coordinated work of the positioning block, lifting rod, clamping plate and other components in the push plate assembly, and maintains a precise position throughout the conveying process, which significantly improves the die bonding quality and the reliability of subsequent processes.

[0020] 3. In this invention, after each substrate body is placed in the collection component, the lead screw and slide in the lifting component gradually descend once to ensure that the new substrate body can be smoothly placed into the placement frame. When the set number is reached, the large electric cylinder no longer presses against the clamping plate, and the entire placement frame moves out of the limiting frame and is transferred to the centralized collection area. This improves management convenience, facilitates large-scale production and automated assembly line operations, and reduces manual intervention and management difficulty.

[0021] 4. The present invention can flexibly adjust the feeding assembly according to different sizes and types of substrates to adapt to diverse production needs. Whether it is a narrow or wide substrate, precise feeding can be achieved by simply adjusting the position of the guide screw and the clamping plate, which enhances the versatility and flexibility of the system.

[0022] 5. The present invention allows for independent adjustment and maintenance of various functional modules such as the feeding assembly, pushing assembly, lifting assembly, and collecting assembly, facilitating configuration and optimization according to actual production needs and improving the scalability and maintenance convenience of the system.

[0023] 6. After die bonding is completed, the substrate body is inspected in real time by an appearance inspection instrument to check for defects or abnormalities, ensuring the quality of each substrate body. The substrate body continues to pass through a thermosetting device to ensure that the adhesive is completely cured, which enhances the bonding force between the LED chip and the substrate body and improves the reliability and lifespan of the product.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0043] Example: An automatic loading and unloading mechanism for LED die bonder substrates, such as... Figures 1-17As shown, the system includes a mobile cabinet 1, a support platform 2, a base 3, an electric rocker arm 4, a crystal-fixing plate 41, a board feeding assembly 5, a board pushing assembly 6, a lifting assembly 9, and a collecting assembly 10. The mobile cabinet 1 serves as the supporting structure for the entire system, housing the control system and other electronic components. An electrical box 11 is installed in the lower part of the mobile cabinet 1. The electrical box 11 is connected to each actuator via wires to form a complete circuit system. Symmetrical heat dissipation vents 12 are opened on the lower part of the inner wall of one side of the mobile cabinet 1 to ensure good heat dissipation of the internal equipment. The support platform 2 is bolted to the top of the mobile mechanism. Three push ports 25 are symmetrically opened at the front of the top of the support platform 2. A dual-axis linear module 21 is installed at the rear center of the top of the support platform 2. A dual-axis linear module 21 is installed at the right center of the top of the support platform 2. A single-axis linear module 24 is installed, and the central feeding assembly 5 is located in front of the dual-axis linear module 21. The three feeding assemblies 5 form an L-shaped array. The feeding assembly 5 in the middle is directly behind one of its push ports 25. The starting end of the single-axis linear module 24 is directly behind the push port 25 on the front side, while the ending end of the single-axis linear module 24 is directly behind the push port 25 near the middle of the front. A support 3 is provided on the rear side of the top of the mobile cabinet 1. Electric rocker arms 4 are symmetrically installed in the middle of the support 3. A die-bonding plate 41 is provided at the output end of the electric rocker arm 4. The electric rocker arm 4 drives the die-bonding plate 41 to move above the substrate, which is responsible for precise positioning and performing die bonding operations, including dispensing and die bonding. It can automatically adjust its position according to the preset program to adapt to different... The substrate body 120 has a specific size and shape. A control panel 31, connected by wires to the electrical box 11, is mounted on one side of the support 3. The control panel 31 provides an intuitive operating interface for easy monitoring and adjustment of the equipment status. The control panel 31 is connected to the electrical box 11 via wires for remote control. Three feeding assemblies 5 are located on the top of the support platform 2. Two of these are respectively located on the connecting plates of the dual-axis linear module 21 and the single-axis linear module 24. The support platform 2 serves as the core area for conveying the substrate body 120. The dual-axis linear module 21 and the single-axis linear module 24 on the support platform can precisely adjust the position of the substrate, ensuring it accurately enters the push port 25 for further processing. Another feeding assembly 5 is located in the middle of the top of the support platform 2. In this system, the starting end of the dual-axis linear module 21 corresponds to the rear of the centrally located feeding assembly 5, while the ending end corresponds to the rear of the side feeding assembly 5. From the starting end to the ending end, two different feeding assemblies 5 are connected, forming a main transport path. This allows the substrate body 120 to start from a relatively central position, undergo a series of processes, and finally reach the side feeding assembly 5 for the next operation. The single-axis linear module 24 provides support for the final transport path, used for subsequent inspection processes and auxiliary transport. Furthermore, all feeding assemblies 5 are at the same horizontal height, ensuring that the substrate body 120 will not shift or be damaged due to height differences during the entire transport process.A pusher assembly 6, which pushes the substrate body 120, is slidably mounted on the board feeding assembly 5. Lifting assemblies 9 are vertically symmetrically arranged at the bottom of the mobile cabinet 1. These lifting assemblies 9, through vertical lifting motion, help the substrate body 120 smoothly enter or leave the push ports 25 on the support platform 2. The lifting assemblies 9 are located below the three push ports 25. A collection assembly 10, which collects the substrate body 120, is slidably mounted on the lifting assembly 9. After the substrate body 120 completes processes such as die bonding, it is pushed by the pusher assembly 6 into the collection assembly 10, awaiting the next processing or transportation. The collection assembly 10 not only provides temporary storage space but also ensures the stability of the substrate body 120 during transportation. The board feeding assembly 5, the pusher assembly 6, and the collection assembly 10 work together to achieve loading and unloading.

The plate feeding assembly 5 is a key part of the transmission of the substrate body 120. It can automatically adjust its position according to the specific width of the substrate body 120 to ensure that the substrate body 120 can be smoothly transported to the designated position. The connecting plates of the dual-axis linear module 21, the connecting plates of the single-axis linear module 24, and the top of the support platform 2 are all symmetrically provided with opposing brackets 51. The lower rear sides of the symmetrical brackets 51 are rotatably connected. A rib 510 is provided, and two guide rods 511 at the same horizontal height as the rib 510 are arranged between the lower parts of the symmetrical brackets 51. Two guide screws 512 adjacent to the corresponding guide rods 511 are arranged between the lower parts of the symmetrical brackets 51. The rib 510, guide rods 511, and guide screws 512 together constitute a precision transmission system, ensuring the accuracy of the substrate body 120 transmission. In each board feeding assembly 5, a motor 52 is installed on the outside of one of the brackets 51. Its output shaft is connected to the inside of the rib 510. The motor 52 drives the rib 510 to rotate, causing the moving seat 55 to slide along the guide rod 511, thereby changing the feeding position. The guide screw 512 is positioned such that its end passes through a bracket 51 on one side, and a toggle disc 53 is provided on the through portion. The toggle disc 53 is used to manually adjust the position of the guide screw 512 to accommodate substrate bodies 120 of different widths. A fixed seat 54 is provided on the end face of one of the board feeding assemblies 5 relative to the other bracket 51. A movable seat 55 is slidably disposed between the outer sides of each guide rod 511. The lower inner part of the movable seat 55 is slidably and rotatably connected to the outer side of the rib rod 510, and both sides of the lower inner part of the movable seat 55 are rotatably connected to two guide screws 512. The two sides of the rib rod 510 are connected to the fixed seat 54 above. A first set of pulleys 56 is rotatably disposed between the movable seat 55 and the fixed seat 54. A second set of pulleys 57 is coaxially rotatably disposed on the side of one of the pulleys in the first set of pulleys 56 on the movable seat 55 and the fixed seat 54. The synchronous belts in the second set of pulleys 57 on the movable seat 55 and the fixed seat 54 extend to their respective ends. The first set of pulleys 56 and the second set of pulleys 57 operate with each other. In addition, the pulley in the first set of pulleys 56 that is connected to the rib 510 is also slidably connected to the rib 510. The fixed seat 54, the movable seat 55, the first set of pulleys 56 and the second set of pulleys 57 work together to ensure the smooth transmission of the substrate body 120.

The top of the support 2 is provided with a baffle frame 22 away from the outer perimeter of the support 3. The bottom of the protective cover 32 is in close contact with the top of the baffle frame 22. The mobile cabinet 1 is symmetrically provided with temporary placement plates 23 on the outside. The front of the support 3 is hinged with a protective cover 32 that covers the surface of the support 2. Heat dissipation windows 33 are provided on both sides of the support 3. After the protective cover 32 and the support 3 are gradually closed, the internal cavities of the two circulate air through the heat dissipation windows 33.

[0046] like Figures 5-10 As shown, the pusher assembly 6 includes an electric slide 61, guide posts 62, auxiliary wheels 63, positioning blocks 64, lifting rods 65, limit clamps 66, clamping plates 661, spring 662, spring 67, small electric cylinders 68, and push blocks 69. The pusher assembly 6 ensures that the base body 120 is safely and stably transferred from the placement frame 104 to the synchronous belt of the pulley group 57, ready for further processing. Each guide rod 511 and each guide screw 512 of the feeding assembly 5 is externally connected to the electric slide 61. The lower part of the electric slide 61 is slidably connected to the corresponding guide rod 511 and rotatably connected to the corresponding guide screw 512. The electric slide 61 can slide on the guide rods 511 and guide screws 512 to provide power to the pusher assembly 6. The electric slide 61 has guide posts 62 on its side and auxiliary wheels 63 installed on the rear top of the electric slide 61. The electric slide 61 has external sliding... A positioning block 64 is provided, with its inner side slidably connected to the guide post 62. A lifting rod 65 is hinged to the top of the positioning block 64, and the lifting rod 65 rests against the auxiliary wheel 63. A limit clamp 66 is provided at the front end of the lifting rod 65, and a clamping plate 661 is slidably provided at the front end of the limit clamp 66. The guide post 62, positioning block 64, and lifting rod 65 cooperate to ensure that the clamping plate 661 can accurately clamp the substrate body 120 and lift it. A spring 662 is provided between the upper end of the clamping plate 661 and the upper end of the limit clamp 66, and a spring 67 is provided between the front end of the positioning block 64 and the bottom end of the lifting rod 65. A small electric cylinder 68 is installed in the middle of the limit frame 101. A push block 69 is provided on the telescopic end of the small electric cylinder 68, and the push block 69 abuts against the rear end of the clamping plate 661. The small electric cylinder 68 and the push block 69 are used to control the movement of the clamping plate 661 to ensure that the substrate body 120 is released at the appropriate time.

[0047] like Figures 11-13As shown, it also includes an electric push rod 7, a wedge block 71, a pressure strip 72, a mating block 721, and springs 73. The tops of the fixed seats 54 and movable seats 55 of the two brackets 51 on the dual-axis linear module 21 are equipped with symmetrical and facing electric push rods 7. The telescopic end of the electric push rod 7 is provided with a wedge block 71. The pressure strip 72 is embedded and slidably arranged in the upper part of the two brackets 51. The pressure strip 72 is close to the synchronous belt of the pulley assembly 2 below. The mating block 721 that abuts against the wedge block 71 is provided at the center of the top of the pressure strip 72. Several springs 73 are symmetrically arranged between the pressure strip 72 and the corresponding fixed seat 54 or movable seat 55. When it is necessary to fix the substrate body 120, the electric push rod 7 extends and pushes the pressure strip 72 down through the wedge block 71 to press the substrate body 120.

[0048] like Figure 2 , Figure 15 and Figure 16 As shown, it also includes an appearance inspection instrument 8 and a thermosetting instrument 81. The appearance inspection instrument 8 is installed between the rear tops of the two brackets 51 on the single-axis linear module 24. The appearance inspection instrument 8 monitors the quality of the substrate in real time and detects any defects in time. The thermosetting instrument 81 is installed between the front tops. The thermosetting instrument 81 ensures that the adhesive is completely cured and improves the bonding strength between the LED chip and the substrate. These two instruments are installed on the top of the brackets 51 of the single-axis linear module 24 to ensure that they can inspect and process the substrate as it passes by.

[0049] like Figure 1-17 As shown, the lifting assembly 9 includes a reinforcing base 91, a second motor 92, a lead screw 93, a guide frame 94, and a slide table 95.

Reinforcing bases 91 are symmetrically arranged at the bottom of the mobile cabinet 1, and the reinforcing bases 91 are correspondingly arranged with three push ports 25. A second motor 92 is installed on the side of the reinforcing base 91, and a vertical lead screw 93 is rotatably mounted in the center of the top of the reinforcing base 91. The lead screw 93 and the second motor 95... The output shaft of 2 is connected, and a guide frame 94 is provided on the top periphery of the reinforcing base 91. The end of the guide frame 94 and the lead screw 93 are close to the push port 25. A slide table 95 is slidably provided on the outside of the guide frame 94. The slide table 95 is rotatably connected to the lead screw 93 inside. The reinforcing base 91 provides the necessary support. The motor 2 92 drives the lead screw 93 to rotate, which drives the slide table 95 to rise or fall. The guide frame 94 ensures the stability of the vertical movement of the slide table 95, so that it can accurately bring the collecting component 10 to the appropriate height.

[0050] like Figure 2 and Figures 15-17As shown, the collection assembly 10 includes a limiting frame 101, a large electric cylinder 102, a stop block 103, a placement frame 104, an adjusting screw 105, and a clamping plate 106. The collection assembly 10 is used to collect the die-bonded substrate body 120 to ensure their safety during subsequent transportation or storage. The limiting frame 101 is installed on the top of the slide table 95 to provide structural support. The large electric cylinder 102 is installed on the side of the limiting frame 101, and the stop block 103 is fixed on the other side of the limiting frame 101. The placement frame 104 is placed inside the limiting frame 101. The placement frame 104 is arranged corresponding to each push port 25. Several symmetrical storage slots are opened on the inner wall of one side of the placement frame 104. The limiting frame 101 is used to store the substrate body 120. One side of the wall is hollowed out. A limiting groove is opened at the center of the bottom of the limiting frame 101. A straight groove is opened at the top of the limiting frame 101. An adjusting screw 105 is rotatably installed on the outside of the straight groove. A pressing plate 106 is slidably installed between the straight groove and the limiting groove. The large electric cylinder 102 controls the movement of the pressing plate 106. A protrusion is provided at the top of the pressing plate 106. The protrusion is threadedly connected to the adjusting screw 105 to ensure the stability of the substrate body 120 in the placement frame 104. The adjusting screw 105 can coordinate with the large electric cylinder 102 to adjust the position of the pressing plate 106 synchronously.

[0051] Initially, the unprocessed substrate body 120 is placed in the central placement frame 104. The movable seat 55 on the feeding assembly 5 can be adjusted according to the width of the substrate body 120. By rotating the torsion disc 53, the position of the guide screw 512 is changed, so that the pulley group 1 56 and pulley group 2 57 on the same side as the movable seat 55 can adapt to substrate bodies 120 of different widths. In addition, the pressure plate 106 is pushed by the large electric cylinder 102. The position of the pressure plate 106 is adjusted according to the actual width of the substrate body 120 to ensure that the substrate body 120 does not shift during the conveying process in the placement frame 104. Subsequently, the push plate assembly 6 on the central feeding assembly 5 drives the positioning block 64 to slide. When the positioning block 64 slides, the lifting rod 65 disengages from the auxiliary wheel 63, and the spring 6... 7 is no longer under pressure and extends, causing the lifting rod 65 to rotate. At the same time, the small electric cylinder 68 drives its telescopic end to retract, and the push block 69 no longer abuts against the clamping plate 661. The clamping plate 661 slides upward by the spring 662. When it approaches the substrate body 120 in the placement frame 104, the clamping plate 661 slides and clamps the side of the substrate body 120. Then, the positioning block 64 is driven back to its original position. The substrate body 120 will be brought from the placement frame 104 to the synchronous belt of the pulley group 57. The motor 52 drives the plate feeding assembly 5 to run and assist in conveying the substrate body 120. After the positioning block 64 is fully reset, the small electric cylinder 68 extends and causes the push block 69 to abut against the clamping plate 661 again. The substrate body 120 is no longer clamped. At the same time, as the positioning block 64 is reset, the lifting rod 65 will be abutted against by the auxiliary wheel 63 again.

[0052] As the board feeding assembly 5 conveys the substrate body 120, it will be delivered to the dual-axis linear module 21 and continuously approach it. The dual-axis linear module 21 is at the starting end, so that the board feeding assembly 5 on it will drive the substrate body 120 to approach the electric rocker arm 4 behind it, ready for the die bonding operation. The electric rocker arm 4 in the support 3 drives the dotting plate 41 to move above the substrate. Through precision control, the LED chip is accurately fixed. During this process, the dotting plate 41 will complete the dispensing and die bonding actions according to the preset program to ensure that each LED chip can be correctly installed on the substrate body 120. In order to prevent the substrate body 120 from moving during die bonding, the electric push rod 7 will drive the pressure bar 72 to descend and fix the substrate body 120. After the die bonding is completed, the substrate body 120 will pass under the board feeding assembly 5 of the single-axis linear module 24 and be inspected in real time by the appearance inspection instrument 8 near the side of the support frame to check for defects or abnormalities.

[0053] Subsequently, the substrate body 120 continues to advance, passing through the thermosetting device 81 to ensure complete curing of the adhesive, enhancing the bonding force between the LED chip and the substrate. After die bonding, the substrate body 120 is fed by the feeding assembly 5 of the dual-axis linear module 21 to the next feeding assembly 5. The substrate body 120 is gradually conveyed into the placement slot of the placement frame 104 by the pulley assembly 57 of the feeding assembly 5, but not completely. At this time, the pusher assembly 6 on the feeding assembly 5 is activated again, causing the lifting rod 65 to drive the clamping plate 661 to press against the substrate body 120. The rear end of the 0 is clamped and pushed into the placement frame 104. After each substrate body 120 is placed, the lead screw 93 and slide table 95 in the lifting component 9 gradually descend once to ensure that the new substrate body 120 can be smoothly placed into the placement frame 104. As more substrate bodies 120 are stored in the placement frame 104, when the set number is reached, the large electric cylinder 102 is activated again and no longer presses against the clamping plate 106. At this time, the placement frame 104 can be moved out of the limiting frame 101 and transferred to the centralized collection area for subsequent processing or packaging.
