Description

Technical Field

[0001] The invention relates to the technical field of LED substrate conveying, and in particular to an automatic loading and unloading mechanism for LED crystal bonding machine substrates. Background Art

[0002] LED die bonder is an automated device used to precisely fix light-emitting diode (LED) chips on a substrate. As a carrier of LED chips, the substrate not only needs to provide mechanical support, but also needs to have good electrical and thermal conductivity to ensure efficient operation and long life 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 loading and unloading LED die bonding device and die bonding method. Although the patent shortens the die bonding time and simplifies the mechanical structure through the die bonding head, glue dripping head and adsorption rod, its design focuses on the die bonding process itself, and pays limited attention to the substrate transportation and unloading links. Specific problems include:

[0004] 1. There is a lack of positioning auxiliary mechanism when placing the PCB board body, which may lead to position deviation during direct transportation, affecting the quality of die bonding and subsequent processes.

[0005] 2. After the die bonding is completed, the PCB board body is unloaded again through the PCB board conveying mechanism, and an effective centralized collection method is not adopted, which increases the difficulty of management and is not conducive to large-scale production and automated assembly line operations.

An electrical box 11 is installed at the lower part of the mobile cabinet 1. The electrical box 11 is connected to each actuator through wires to form a complete circuit system. Symmetrical heat dissipation ports 12 are opened at the lower part of the inner wall on one side of the mobile cabinet 1 to ensure good heat dissipation of the internal equipment. A support platform 2 is provided on the top of the mobile mechanism through bolts. Three pushing 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 middle of the top of the support platform 2. A single-axis linear module 24 is installed, and the middle feeding plate assembly 5 is located in front of the double-axis linear module 21. The feeding plate assemblies 5 at three locations form an L-shaped array. The feeding plate assembly 5 located in the middle is directly behind one of the push ports 25. The starting end of the single-axis linear module 24 is directly behind the push port 25 on the front side, and the terminal end of the single-axis linear module 24 is directly behind the push port 25 on the front edge. A support seat 3 is provided on the rear side of the top of the mobile cabinet 1. An electric rocker 4 is symmetrically installed in the middle of the support seat 3. A crystal plate 41 is provided at the output end of the electric rocker 4. The electric rocker 4 drives the crystal plate 41 to move above the substrate, which is responsible for precise positioning and performing solid crystal actions, including dispensing and solid crystal. It can automatically adjust its position according to a preset program to adapt to different sizes. The substrate body 120 is of different size and shape. A control panel 31 connected to the electrical box 11 by wires is installed on one side of the outside of the support 3. The control panel 31 provides an intuitive operation interface for users to monitor and adjust the equipment status. The control panel 31 is connected to the electrical box 11 by wires to realize remote control. Three board delivery components 5 are arranged on the top of the support platform 2, two of which are respectively arranged on the connecting plates of the double-axis linear module 21 and the single-axis linear module 24.

The screw rod 93 and the motor 92 are connected. 2 is connected, a guide frame 94 is arranged on the outer periphery of the top of the reinforcement seat 91, the terminal ends of the guide frame 94 and the screw rod 93 are close to the push port 25, a slide 95 is slidingly arranged on the outside of the guide frame 94, and the inside of the slide 95 is rotatably connected with the screw rod 93; the reinforcement seat 91 provides the necessary support, the motor 92 drives the screw rod 93 to rotate, and drives the slide 95 to rise or fall, and the guide frame 94 ensures the stability of the vertical movement of the slide 95, so that it can accurately bring the collection component 10 to a suitable height.

[0050] like Figure 2 and Figure 15-17As shown, the collecting assembly 10 includes a limiting frame 101, a large electric cylinder 102, a stopper 103, a placement frame 104, an adjusting screw 105 and a pressing plate 106. The collecting assembly 10 is used to store the substrate bodies 120 that have completed the solid crystal to ensure their safety during subsequent transportation or storage. The limiting frame 101 is installed on the top of the slide 95 to provide structural support. The large electric cylinder 102 is installed on the side of the limiting frame 101, and the stopper 103 is fixed on the other side of the limiting frame 101. A placement frame 104 is placed inside the limiting frame 101. The placement frame 104 is arranged corresponding to each push port 25. The inner wall surface of one side of the placement frame 104 is provided with a plurality of symmetrical storage grooves. It is used to store the substrate body 120. The wall on one side of the limit frame 101 is hollowed out. A limit slot is provided in the center of the bottom of the limit frame 101. A straight slot is provided on the top of the limit frame 101. An adjusting screw 105 is provided for rotating outside the straight slot. A clamping plate 106 is provided for sliding between the straight slot and the limit slot. The large electric cylinder 102 controls the movement of the clamping plate 106. A protrusion is provided on the top of the clamping 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, and the adjusting screw 105 can cooperate with the large electric cylinder 102 to synchronously adjust the position of the clamping plate 106.

[0051] Initially, the unprocessed substrate body 120 is placed in the placement frame 104 in the middle. The movable seat 55 on the feeding plate assembly 5 can be adjusted according to the width of the substrate body 120. By rotating the torsion plate 53, the position of the guide screw 512 is changed, so that the pulley group 1 56 and the pulley group 2 57 on the same side of the movable seat 55 can adapt to substrate bodies 120 of different widths. In addition, the clamping plate 106 is pushed by the large electric cylinder 102. The position of the clamping plate 106 is adjusted according to the actual width of the substrate body 120 to ensure that the substrate body 120 will not deviate during the transmission process in the placement frame 104. Subsequently, the push plate assembly 6 on the middle feeding plate assembly 5 drives the positioning block 64 to slide. When the positioning block 64 slides, the lifting rod 65 is out of contact with the auxiliary wheel 63, and the spring 2 6 7 is no longer compressed and stretched, driving 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 1 662. When it approaches the substrate body 120 in the placement frame 104, the clamping plate 661 clamps the side of the substrate body 120 as it slides, and then drives the positioning block 64 to return. The substrate body 120 will be brought from the placement frame 104 to the top of the synchronous belt of the pulley group 2 57, and the motor 1 52 drives the feeding plate assembly 5 to run to assist in conveying the substrate body 120. After the positioning block 64 is completely reset, the small electric cylinder 68 extends to make the push block 69 abut against the clamping plate 661 again, and 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 by the auxiliary wheel 63 again;

[0052] As the plate delivery assembly 5 is conveyed, the substrate body 120 will be delivered to the dual-axis linear module 21 and will continue to approach it. The dual-axis linear module 21 is at the starting end, so that the plate delivery assembly 5 on it drives the substrate body 120 to approach the electric rocker arm 4 at the rear to prepare for the crystal fixing operation; the electric rocker arm 4 in the support 3 drives the crystal spotting plate 41 to move above the substrate, and realizes the precise fixation of the LED chip through precise control. During this process, the crystal spotting plate 41 will complete the dispensing and crystal fixing 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 crystal fixing, the electric push rod 7 will fix the substrate body 120 by driving the pressure bar 72 to descend. After the crystal fixing is completed, the substrate body 120 will pass under the plate delivery assembly 5 of the single-axis linear module 24, and the appearance detector 8 near the side of the carrier will perform real-time inspection on it to check whether there are defects or abnormalities;

[0053] Subsequently, the substrate body 120 continues to move forward and passes through the thermal curing device 81 to ensure that the glue is completely cured and the bonding force between the LED chip and the substrate is enhanced. The substrate body 120 after the solidification is sent to the next feeding plate assembly 5 by the feeding plate assembly 5 of the dual-axis linear module 21. The substrate body 120 gradually enters the placement groove of the placement frame 104 along with the conveyance of the pulley group 2 57 of the feeding plate assembly 5, but does not enter completely. At this time, the push plate assembly 6 on the feeding plate assembly 5 is started again, so that the lifting rod 65 drives the clamping plate 661 to press the substrate body 120. 0 is clamped at the rear end to assist in pushing it into the placement frame 104. Each time a substrate body 120 is placed, the screw rod 93 and the slide 95 in the lifting assembly 9 gradually descend once to ensure that the new substrate body 120 can be smoothly placed in 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 moves again and no longer resists the clamping plate 106. At this time, the placement frame 104 can be moved out of the limiting frame 101 as a whole and transferred to the centralized collection area for subsequent processing or packaging.
