Description

Technical Field

[0001] This utility model relates to the field of light source placement machine technology, and in particular to an anti-static semiconductor light source placement machine. Background Technology

[0002] In the current booming semiconductor industry, semiconductor light source placement machines, as key equipment in the semiconductor light source production process, directly affect product quality and production efficiency. Semiconductor light sources are extremely sensitive to static electricity during manufacturing; even minute electrostatic discharges can damage semiconductor components. Simultaneously, placement machines need to accurately identify the position and status of components; therefore, anti-static systems and vision inspection systems are indispensable components. As semiconductor packaging technology advances towards miniaturization and high precision, higher demands are placed on the functionality and reliability of placement machines. Optimizing the relevant structure of placement machines has become an important direction for continuous exploration in the industry.

[0003] Existing anti-static semiconductor light source placement machines typically employ fixed-mount vision inspection systems and ion fans in their mechanical structure design and technical principles. The vision inspection system uses cameras and image processing algorithms to locate and inspect components; its structure is often tightly fixed to the main frame of the placement machine, requiring various tools such as screwdrivers for disassembly and installation. The ion fan, on the other hand, is installed at a fixed angle inside the equipment, continuously releasing ions to neutralize static electricity. Its positional stability relies primarily on the rigid connection of the mechanical support, making it difficult to flexibly adjust the angle according to actual needs during use.

[0004] However, existing pick-and-place machines have significant shortcomings in practical use. One major drawback is the inconvenience of disassembling and maintaining the vision inspection system. Because the vision inspection system is connected to the main frame of the pick-and-place machine in a complex manner, when the system malfunctions or requires cleaning or maintenance, operators must use various tools and follow specific steps to disassemble the equipment. This not only consumes a significant amount of time and effort but also demands a high level of professional skill from the operators. This process not only increases maintenance costs but also damages components due to frequent disassembly and assembly. Furthermore, prolonged downtime severely impacts production schedules, making it difficult to meet the high-efficiency and rapid demands of modern semiconductor manufacturing. Therefore, an anti-static semiconductor light source pick-and-place machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-static semiconductor light source placement machine, which aims to improve the problem that the existing technology requires multiple tools to be used when disassembling and assembling vision detectors, making disassembly inconvenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-static semiconductor light source pick-and-place machine includes a base, a pick-and-place machine fixedly connected to the top of the base, a conveyor belt inside the pick-and-place machine, a transmission frame inside the pick-and-place machine, a vision detector on the outer wall of the transmission frame, a disassembly and assembly assembly on the outer wall of the transmission frame, a plasma fan inside the pick-and-place machine, and an adjustment assembly inside the pick-and-place machine.

[0008] The assembly / disassembly assembly includes an elliptical locking post. The outer wall of the elliptical locking post is disposed on the outer wall of the transmission frame. The outer wall of the elliptical locking post is slidably connected to the inside of the vision detector. A connecting frame is fixedly connected to the outer wall of the transmission frame. The outer wall of the elliptical locking post is slidably connected to the inside of the connecting frame. A sliding groove is provided inside the connecting frame. A push rod is fixedly connected to the outer wall of the elliptical locking post. The outer wall of the push rod is slidably connected to the inside of the sliding groove. A push groove is provided inside the push rod. A reset assembly is provided inside the connecting frame.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a spring, the outer wall of which is disposed inside the connecting frame, one end of which is fixedly connected to the inner wall of the slide groove, and the other end of which is fixedly connected to one end of the elliptical locking post.

[0011] As a further description of the above technical solution:

[0012] The adjustment assembly includes a rotating column, the outer wall of which is disposed inside the pick and place machine.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the rotating column is fixedly connected to the bottom of the plasma blower, and a fixed base is fixedly connected inside the patch machine.

[0015] As a further description of the above technical solution:

[0016] A fixed disc is fixedly connected to the top of the fixed base, and a locking tooth is fixedly connected to the outer wall of the fixed disc.

[0017] As a further description of the above technical solution:

[0018] A connecting column is fixedly connected to the outer wall of the fixed disk, and a limiting disk is fixedly connected to one end of the connecting column.

[0019] As a further description of the above technical solution:

[0020] A limiting groove is provided at the bottom of the rotating column, and the outer wall of the limiting disk is slidably connected inside the limiting groove. A second locking tooth is fixedly connected to the outer wall of the rotating column, and the second locking tooth meshes with the first locking tooth.

[0021] As a further description of the above technical solution:

[0022] A second spring is sleeved on the outer wall of the connecting column. One end of the second spring is rotatably connected to the inner wall of the limiting groove, and the other end of the second spring is fixedly connected to the outer wall of the limiting disc.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the elliptical locking post achieves its movement function by pushing the push groove. When the push groove is pushed, the push groove drives the push rod and spring one, and cooperates with the sliding groove to realize the sliding of the elliptical locking post inside the vision detector, thereby facilitating the disassembly and assembly of the vision detector, making it convenient for maintenance, replacement and movement. This solves the problem that existing vision detectors require multiple tools to disassemble and assemble, making disassembly and assembly difficult, and improves the convenience of disassembly, assembly and maintenance of the vision detector.

[0025] 2. In this utility model, the plasma fan achieves its movement function by pulling the rotating column. When the rotating column is pulled, the rotating column drives the spring and the limiting disk and cooperates with the locking teeth to make the rotating column rotate on the outer wall of the limiting disk, thereby conveniently rotating the plasma fan and facilitating static elimination at different positions. This solves the problem of not being able to conveniently eliminate static electricity from light sources at different positions and improves the applicability of static elimination.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of an anti-static semiconductor light source placement machine, comprising a base 1 made of high-strength cast iron, which undergoes an aging treatment process to eliminate internal stress. A shock-absorbing rubber pad is installed at the bottom of the base 1 to stably support the placement machine 3 and effectively reduce the impact of vibrations during operation on the placement accuracy of the semiconductor light source, preventing component misalignment due to vibration and ensuring production quality. The placement machine 3 is fixedly connected to the top of the base 1. A conveyor belt 2 and a transmission frame 4 are installed inside the placement machine 3. The transmission frame 4 moves via a high-precision linear guide and a servo motor drive system, achieving micron-level positioning accuracy. Combined with the control system inside the placement machine 3, it can accurately place semiconductor light sources... The source is mounted onto the target substrate. The outer wall of the transmission frame 4 is equipped with a vision detector 6, which consists of a high-resolution industrial camera, an optical lens, and an image processing module. It is used to collect image information of the semiconductor light source and the substrate in real time. Through image recognition algorithms, the position, angle, polarity and other parameters of the components are accurately detected and calibrated to ensure the accuracy of the placement position. The placement error can be controlled within a very small range. The outer wall of the transmission frame 4 is equipped with a disassembly and assembly assembly. The inside of the pick-and-place machine 3 is equipped with a plasma fan 5, which consists of an ion generator, a fan and an air outlet. It is used to generate and blow out an airflow with positive and negative ions to eliminate static electricity from the semiconductor light source and prevent static electricity from damaging the components. The inside of the pick-and-place machine 3 is equipped with an adjustment assembly.

[0035] The assembly and disassembly components include an elliptical locking post 8, made of stainless steel with a polished surface. Its outer wall is set on the outer wall of the transmission frame 4. The outer wall of the elliptical locking post 8 is slidably connected to a corresponding slot inside the vision detector 6, thus fixing the vision detector 6 through its engagement with the slot. A connecting frame 7 is fixedly connected to the outer wall of the transmission frame 4, with the outer wall of the elliptical locking post 8 slidably connected inside. A sliding groove 11 is provided inside the connecting frame 7. A push rod 12 is fixedly connected to the outer wall of the elliptical locking post 8, with its outer wall slidably connected inside the sliding groove 11. A push groove 9 is provided inside the push rod 12. A reset assembly is provided inside the connecting frame 7, including a spring 10. The outer wall of the spring 10 is set inside the connecting frame 7, with one end fixedly connected to the inner wall of the sliding groove 11 and the other end fixedly connected to one end of the elliptical locking post 8.

[0036] Specifically, in the semiconductor light source placement process, the semiconductor light source material to be processed is placed on top of conveyor belt 2. Conveyor belt 2, with its stable transmission system, transports the semiconductor light source to the designated station at a uniform speed and smoothly. Once the semiconductor light source arrives at the placement area, the drive frame 4 begins its core function. Its high-precision placement head, according to a preset program, picks up the semiconductor light source from the feeder and places it onto the target substrate with micron-level precision. Throughout the placement process, anti-static measures and accurate detection are crucial for ensuring product quality. Plasma fans 5 operate continuously, releasing a large number of positive and negative ions to quickly neutralize the static electricity generated on the surface of the semiconductor light source, effectively preventing component damage caused by static accumulation and ensuring the stability and reliability of the placement process. Simultaneously, a vision detector 6 operates in real time, utilizing a high-resolution camera and... Advanced image recognition algorithms accurately detect and calibrate parameters such as the position, angle, and polarity of the semiconductor light source, ensuring the accuracy of the patch placement. As the equipment is used for longer periods, the visual detector 6 may experience reduced detection accuracy due to dust accumulation and component aging. In such cases, the operator simply pushes the pusher 9, which causes the push rod 12 to slide smoothly within the slide groove 11, thereby pushing the elliptical locking post 8 out of the visual detector 6. During this process, the spring 10 is compressed. Once the elliptical locking post 8 is completely disengaged from the slot of the visual detector 6, the visual detector 6 can be easily removed for cleaning, repair, or replacement. After maintenance, the visual detector 6 is returned to its original position, the pusher 9 is released, and the spring 10 quickly rebounds, causing the elliptical locking post 8 to re-enter the slot of the visual detector 6, completing the fixation and ensuring stable and accurate subsequent detection work.

[0037] Reference Figure 2 and Figure 5The adjustment assembly includes a rotating column 15, which is made of high-strength alloy steel and hardened to enhance surface hardness. Its outer wall is securely installed in pre-drilled mounting holes inside the placement machine 3. The top of the rotating column 15 is welded to the bottom of the plasma fan 5 to support the plasma fan 5 and drive it for angle adjustment, ensuring the stability and reliability of the plasma fan 5 during adjustment. The outer wall of the rotating column 15 is located inside the placement machine 3 and is fixedly connected to the bottom of the plasma fan 5. A fixed base 13, made of cast aluminum and die-cast, is fixedly connected inside the placement machine 3, providing a stable mounting foundation for the entire adjustment assembly and preventing shaking during adjustment. To improve the static electricity elimination effect, a fixed disc 19 is fixedly connected to the top of the fixed base 13. A locking tooth 20 is fixedly connected to the outer wall of the fixed disc 19. A connecting column 18 is fixedly connected to the outer wall of the fixed disc 19. A limiting disc 14 is fixedly connected to one end of the connecting column 18. A limiting groove 17 is opened at the bottom of the rotating column 15. The outer wall of the limiting disc 14 is slidably connected to the inside of the limiting groove 17. A locking tooth 21 is fixedly connected to the outer wall of the rotating column 15. The locking tooth 21 meshes with the locking tooth 20 to achieve positioning and fixation of the plasma fan 5 after angle adjustment, preventing it from shifting its angle due to vibration and other factors during operation. A spring 16 is sleeved on the outer wall of the connecting column 18. One end of the spring 16 is rotatably connected to the inner wall of the limiting groove 17, and the other end of the spring 16 is fixedly connected to the outer wall of the limiting disc 14.

[0038] Specifically, during the semiconductor light source mounting process, different workstations and components have varying angle requirements for electrostatic discharge (ESD) elimination. This makes the angle adjustment function of the plasma blower 5 particularly important. When the angle of the plasma blower 5 needs adjustment, the operator simply pulls the rotating column 15. The rotating column 15 slides along the outer wall of the connecting column 18, compressing the second spring 16 in the process. As the rotating column 15 moves, the originally meshed locking teeth 20 and 21 gradually separate, releasing the locking state. The operator can then flexibly rotate the plasma blower 5 to adjust it to the appropriate angle to meet the ESD elimination requirements of different positions and types of semiconductor light sources. After adjustment, releasing the rotating column 15 causes the second spring 16 to quickly rebound, returning the rotating column 15 to its initial position. The locking teeth 20 and 21 then re-engage tightly, firmly fixing the angle of the plasma blower 5 and ensuring stable and efficient ESD elimination.

[0039] Working principle: When mounting semiconductor light sources, they are placed on top of conveyor belt 2 for transportation, and then mounted by transmission frame 4. During the mounting process, the plasma fan 5 eliminates static electricity. At the same time, the mounting is detected by vision detector 6. When the usage time is long, the pusher 9 can drive the push rod 12 to slide inside the slide groove 11, which moves the elliptical locking post 8 to slide out from inside the vision detector 6 and compress the spring 10, thereby removing the vision detector 6 for maintenance. Then it is put back, the pusher 9 is released, and the spring 10 rebounds to drive the elliptical locking post 8 back into the vision detector 6 for fixation, maintaining stable detection.

[0040] In addition, when it is necessary to adjust the angle of the plasma fan 5, the rotating column 15 can be pulled. The rotating column 15 slides on the outer wall of the connecting column 18, compressing the second spring 16, thereby disengaging the first locking tooth 20 and the second locking tooth 21, so that the angle of the plasma fan 5 can be adjusted. After that, the rotating column 15 is released, and the second spring 16 rebounds to drive the rotating column 15 back to its original position, re-engaging the first locking tooth 20 and the second locking tooth 21 to maintain the angle fixed, and eliminating static electricity at different angles.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
