This directly affects the performance stability and lifespan of semiconductor devices. As the semiconductor industry develops towards higher precision, miniaturization, and higher integration, higher requirements are placed on the positional accuracy of dispensing, the accuracy of adhesive mixing ratios, and dispensing efficiency.

The vent hole at the upper end of the mixing nozzle, in conjunction with the sealing rod, allows for the control of the sealing rod's lifting and lowering via a first hydraulic rod, flexibly adjusting the air pressure environment within the mixing nozzle. This effectively prevents problems such as air bubbles and uneven curing during the mixing process. Furthermore, the stable connection design between the mixing nozzle and the dispensing nozzle ensures smooth delivery of the mixed colloid, further improving the stability of dispensing quality.

[0016] Furthermore, in this invention, the two conveyor belts in the conveying component are synchronously driven, which can stably carry the workpiece and achieve continuous conveying. In conjunction with the load-bearing plate located below the conveyor belt, the weight of the workpiece can be effectively distributed, avoiding conveying deviation caused by conveyor belt deformation due to load. The tensioning bolt can adjust the position of the round rod, thereby adjusting the tension of the conveyor belt. The tensioning wheel can adjust the tension of the first connecting belt, ensuring the stability of the transmission structure and reducing conveying jams or uneven speeds caused by belt slack, ensuring smooth and accurate workpiece conveying. In the top material component, the second hydraulic rod pushes the bottom block to slide. The inclined structure of the bottom block cooperates with the mating block to drive the top plate to rise and fall along the guide rod, achieving precise lifting and positioning of the workpiece. The third hydraulic rod drives the baffle plate to move, which can block and limit the workpiece when it is conveyed to the designated position. The combined effect of the two can ensure that the workpiece is in the preset precise position before dispensing, avoiding workpiece displacement that affects dispensing accuracy.

A baffle plate 332 is installed on the piston rod of the third hydraulic rod 331. Its function is: when the second hydraulic rod 313 is run, its piston rod will drive the base block 312 on the base 31 to slide. The inclined structure of the base block 312 cooperates with the mating block 321 at the lower end of the top plate 32, which can push the top plate 32 to rise along the four guide rods 311 on the base 31, lifting the workpiece to the required dispensing height. When the third hydraulic rod 331 on the cylinder seat 33 is run, its piston rod will drive the baffle plate 332 to move, which can stop the workpiece from continuing to be conveyed. Together with the top plate 32, the workpiece can be accurately positioned, which facilitates the subsequent dispensing operation.

[0036] In Example 3, based on Examples 1 and 2, a right rail seat 4 and a left rail seat 41 are provided on the partition 14. Two support plates 42 are installed at the lower ends of both the right and left rail seats 4 and 41. A transverse rail seat 44 that can slide back and forth is installed on both the right and left rail seats 4 and 41. A first lead screw 43 and a first motor 431 are installed on the right rail seat 4. The output shaft of the first motor 431 is connected to the front end of the first lead screw 43 via a coupling. The first lead screw 43 is threaded into the lower end of the transverse rail seat 44. A movable part that can slide left and right is installed on the transverse rail seat 44. The movable plate 45 has a mating seat 451 installed at its rear end. A second lead screw 441 and a second motor 442 are installed inside the transverse rail seat 44. The output shaft of the second motor 442 is connected to the right end of the second lead screw 441 via a coupling. The second lead screw 441 is threadedly engaged with the mating seat 451. A liftable lifting seat 452 is installed on the movable plate 45, and a third lead screw 453 is also installed on the movable plate 45, threadedly engaged with the lifting seat 452. A sliding plate 4541 is installed on the movable plate 45, and the sliding plate 4541 has a waist-shaped... A third motor 454 is mounted on the slide plate 4541. Both the output shaft of the third motor 454 and the third lead screw 453 are equipped with pulleys. A second connecting belt 4543 connects the two pulleys. Its function is as follows: When the first motor 431 is running, its output shaft drives the first lead screw 43 to rotate via a coupling. Because the first lead screw 43 is threaded with the lower end of the transverse rail seat 44, it can drive the transverse rail seat 44 to slide back and forth along the right rail seat 4 and the left rail seat 41. When the second motor 442 is running, its output shaft drives the second lead screw 441 to rotate via a coupling. Because the No. 2 lead screw 441 is threadedly engaged with the mating seat 451 at the rear end of the movable plate 45, it can drive the movable plate 45 to slide left and right along the transverse rail seat 44, and run the third motor 454. Its output shaft drives the No. 3 lead screw 453 to rotate through the pulley and the second connecting belt 4543. Because the No. 3 lead screw 453 is threadedly engaged with the lifting seat 452, it can drive the lifting seat 452 to rise and fall along the movable plate 45. Through the coordination of the above components, the lifting seat 452 can be precisely adjusted in three directions: front and back, left and right, and up and down, to adapt to the dispensing needs of different positions and heights.

[0037] Working principle of the invention: During operation, the equipment is first started via the control console 13 on the base frame 1. The drive motor 242 in the conveying component 2 drives the transmission rod 212 to rotate via the reducer 241 and the first connecting belt 2411, causing the conveyor belt 215 to rotate and transport the tray containing the semiconductor workpiece. During this process, the tensioning wheel 2431 can be adjusted via the adjusting plate 243 to tension the first connecting belt 2411, or the tensioning bolt 232 can be tightened to ensure stable conveying. When the workpiece is transported to the top material component 3, the third hydraulic rod 331 on the cylinder seat 33 pushes... The movable baffle 332 extends to block the workpiece. Then, the second hydraulic rod 313 on the base 31 pushes the bottom block 312 to slide. The inclined structure of the bottom block 312 cooperates with the mating block 321 at the lower end of the top plate 32, driving the top plate 32 to rise along the four guide rods 311 to lift the workpiece and complete the positioning. Next, the first motor 431 on the right rail seat 4 drives the transverse rail seat 44 to slide back and forth along the right rail seat 4 and the left rail seat 41 through the first lead screw 43. The second motor 442 in the transverse rail seat 44 drives the movable plate 45 to slide left and right through the second lead screw 441 and the mating seat 451. The third motor 454 on the movable plate 45 drives the lifting seat 452 to rise and fall via the second connecting belt 4543 and the third lead screw 453, thereby adjusting the position of the connecting plate 46 and the plate base 461 so that the dispensing nozzles 4636 below the glue cylinders A4631 and B4632 are aligned with the glue dispensing position on the workpiece. Then, the fourth motor 4621 on the plate base 461 drives the fourth lead screw 4614 to rotate via the third connecting belt 4622, causing the sliding plate 4611 to slide and drive the first push rod 4612 and the second push rod 4613 to simultaneously push the glue cylinder A4631. The adhesive in the adhesive cartridge B4632 is mixed by the mixing nozzle 4633 and then flows out from the dispensing nozzle 4636 to complete the dispensing. During this process, the air pressure can be adjusted by controlling the vent of the mixing nozzle 4633 through the sealing rod 4638 via the first hydraulic rod 4637. At the same time, the vision camera 467 on the connecting plate 46 collects images with the assistance of the supplementary light 4652 to monitor the dispensing position and quality in real time. If the adhesive needs to be replaced, the adhesive cartridge A4631 or adhesive cartridge B4632 can be directly removed from the mounting slot of the support 4639 for replacement. The whole process realizes online precision dispensing of semiconductor workpieces.
