Description

Technical Field

[0001] This utility model relates to the technical field of material conveying equipment, specifically to a material conveying equipment for chip packaging processing. Background Technology

[0002] A chip is an integrated circuit and one of the main components of modern electronic devices. Chips are produced on wafers using processes such as photolithography. After being packaged, they become the chips we see today. There are many chip packaging methods, the most common being plastic encapsulation and glue encapsulation, as well as metal encapsulation for higher quality requirements.

[0003] In the packaging process, especially in plastic encapsulation, the chip needs to be placed into a mold, then injected and cooled to solidify. The chip handling and removal and transport after solidification also require manual intervention. This manual intervention not only reduces efficiency but also affects the chip itself. Therefore, a feeding device for chip packaging processing is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that manual intervention is required during the chip encapsulation process. This manual intervention not only reduces efficiency but also affects the chip itself. Therefore, this invention provides a material conveying device for chip packaging, which enables the chip material conveying function to be completed without manual intervention.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a feeding device for chip packaging processing, including a processing table, a lower mold fixedly connected to the top side wall of the processing table near one edge, a material conveyor belt provided on the side of the processing table away from the lower mold, a main telescopic rod rotatably provided on the top side wall of the processing table between the lower mold and the material conveyor belt, fixed plates fixedly connected to both sides of the output end of the main telescopic rod, a telescopic sleeve rod telescopically sleeved on the fixed plate, a horizontal plate fixedly connected to the end of the telescopic sleeve rod away from the fixed plate, and two suction cups provided on the bottom side wall of the horizontal plate.

[0006] As a preferred technical solution of this utility model, a bottom groove is provided in the middle of the top side wall of the processing table, and a rotary motor is detachably embedded in the bottom groove. The output end of the rotary motor is detachably connected to the bottom side wall of the main telescopic rod.

[0007] As a preferred technical solution of this utility model, the telescopic sleeve rod has a hollow structure, and a secondary telescopic rod is embedded and connected to one end of the fixed plate extending into the telescopic sleeve rod. The output end of the secondary telescopic rod is detachably connected to one end of the side wall of the telescopic sleeve rod.

[0008] As a preferred technical solution of this utility model, the bottom sidewalls of the two horizontal plates are provided with sliding grooves, and a bidirectional screw is rotatably connected in the sliding grooves. Both ends of the bidirectional screw are threaded with suction cups. An adjustment motor is detachably connected to the outer wall of one end of the horizontal plate. The output end of the adjustment motor extends into the sliding groove and is detachably connected to one end of the bidirectional screw.

[0009] As a preferred technical solution of this utility model, a lifting control plate is fixedly connected to the top side wall of one end of the processing table located on the lower mold. A lifting groove is opened on one side of the lifting control plate, and a slider is slidably connected in the lifting groove. An upper mold is set above the lower mold. The upper mold is detachably connected to one side of the slider. A mold cavity is opened in the lower mold. A feeding conveyor belt is set below the incoming material conveyor belt. The feeding conveyor belt is 5-10cm longer than the incoming material conveyor belt.

[0010] This invention has the following advantages: When it is necessary to transport chips, the horizontal plate is extended above the mold cavity, and then the packaged chip is adsorbed by the suction cup. At the same time, another suction cup adsorbs the chip to be packaged on the incoming material conveyor belt. The chip to be packaged is moved to the top of the mold cavity by the rotation of the main telescopic rod, and then placed into the mold cavity. After adjusting the position of the adsorbed packaged chip, it is finally placed on the feeding conveyor belt and sent away. This achieves the effect of simultaneous feeding and discharging, and the whole process does not require manual intervention, which improves the conveying efficiency and avoids the problem of damage to the chips caused by human labor.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3This utility model discloses a feeding device for chip packaging processing, including a processing table 1. A lower mold 2 is fixedly connected to the top side wall of the processing table 1 near one edge. A material conveyor belt 10 is provided on the side of the processing table 1 away from the lower mold 2. A main telescopic rod 5 is rotatably provided on the top side wall of the processing table 1 between the lower mold 2 and the material conveyor belt 10. Fixing plates 6 are fixedly connected to both sides of the output end of the main telescopic rod 5. A telescopic sleeve rod 7 is telescopically sleeved on the fixing plate 6. A horizontal plate 8 is fixedly connected to the end of the telescopic sleeve rod 7 away from the fixing plate 6. Two suction cups 9 are provided on the bottom side wall of the horizontal plate 8.

[0017] A bottom groove 16 is provided in the middle of the top side wall of the processing table 1. A rotary motor 17 is detachably embedded in the bottom groove 16. The output end of the rotary motor 17 is detachably connected to the bottom side wall of the main telescopic rod 5. The telescopic sleeve rod 7 has a hollow structure. A secondary telescopic rod 15 is embedded in one end of the fixed plate 6 that extends into the telescopic sleeve rod 7. The output end of the secondary telescopic rod 15 is detachably connected to one end of the side wall inside the telescopic sleeve rod 7.

[0018] The technical effect of this solution is as follows: the secondary telescopic rod 15 is activated to drive the two horizontal plates 8 to extend out. Then, the main telescopic rod 5 descends to drive the suction cup 9 to adsorb the packaged chip and the chip to be packaged. Then, the main telescopic rod 5 is rotated to change the position of the two pairs of chips, and the chip to be packaged is placed into the mold cavity. At the same time, the packaged chip is placed on the feeding conveyor belt 11 and sent away, realizing the function of simultaneous feeding and discharging, improving the efficiency of material conveying. Since no manual intervention is required, the workload of the staff is reduced, and the problems caused by human intervention are avoided.

[0019] The bottom sidewalls of the two horizontal plates 8 are provided with grooves 12. A bidirectional screw 13 is rotatably connected in the grooves 12. Both ends of the bidirectional screw 13 are threaded with suction cups 9. An adjustment motor 14 is detachably connected to the outer wall of one end of the horizontal plate 8. The output end of the adjustment motor 14 extends into the groove 12 and is detachably connected to one end of the bidirectional screw 13.

[0020] The technical effect of this solution is as follows: the starting adjustment motor 14 drives the bidirectional screw 13 to rotate, and the distance between the two suction cups 9 can be adjusted through the principle of threaded connection, thereby adapting to mold cavities with different distances and improving the practicality of the application.

[0021] A lifting control plate 3 is fixedly connected to the top side wall of one end of the processing table 1 located at the lower mold 2. A lifting groove is opened on one side of the lifting control plate 3, and a slider is slidably connected in the lifting groove. An upper mold 4 is set above the lower mold 2. The upper mold 4 is detachably connected to one side of the slider. A mold cavity is opened in the lower mold 2. A feeding conveyor belt 11 is set below the incoming material conveyor belt 10. The feeding conveyor belt 11 is 5-10cm longer than the incoming material conveyor belt 10.

[0022] The technical effects of this solution are as follows: the upper mold 4 is raised and lowered by the lifting control board 3, which facilitates mold separation. Separating the upper mold 4 and the lower mold 2 makes it easier to pick up and put down the chip. The raising and lowering of the upper mold 4 is achieved by the cylinder driving the slider, which improves the reliability of the lifting adjustment. At the same time, the incoming material conveyor belt 10 and the feeding conveyor belt 11 are set with different lengths to facilitate the differentiation of their functions and avoid interference in picking up and putting down materials.

[0023] Specifically, in use of this invention, after packaging is completed, the upper mold 4 is raised by the slider, and then the main telescopic rod 5 is raised to move the horizontal plate 8 above the lower mold 2. Then, the secondary telescopic rod 15 is activated to extend the horizontal plate 8 onto the mold cavity. At the same time, another horizontal plate 8 will extend simultaneously above the material conveyor belt 10. Then, the horizontal plate 8 is lowered by the drive of the main telescopic rod 5. The descent of the horizontal plate 8 applies pressure to the suction cup 9, causing it to adsorb the chip in the mold cavity and on the material conveyor belt 10. Then, the chip is lifted by the main telescopic rod 5. Then, the position of the two horizontal plates 8 is adjusted by the drive of the rotary motor 17. First, the packaged chip is placed into the mold cavity, and then the corresponding horizontal plate 8 is retracted. Then, the main telescopic rod 5 is lowered to place the packaged chip onto the feeding conveyor belt 11. This completes the chip packaging loading and unloading. This method can greatly improve the overall processing efficiency and does not require manual intervention.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
