Description

Technical Field

[0001] This utility model relates to a high-precision plug-in type automated packaging system for crystal oscillators, belonging to the technical field of high-precision crystal oscillator cold pressing welding tooling. Background Technology

[0002] The components of plug-in crystal oscillators are relatively small and need to be prefabricated into bases and metal covers for cold pressing, welding, and encapsulation. The bases and metal covers themselves have a certain curvature, and the dimensions of the prefabricated components will be deformed due to stress. A certain degree of position adjustment is required during splicing. The encapsulation process requires relative diffusion of metal atoms, which requires very high pressure. Cold pressing welding is difficult and the tooling requirements are high.

[0003] Currently, several multi-mode cold-press welding fixtures for through-hole crystal oscillators have emerged on the market, capable of processing multiple parts simultaneously. However, when processing multiple parts at once, the varying thicknesses of these parts lead to poor airtightness, making it difficult to maintain production in an ultra-high vacuum environment throughout the process. While processing a single part with the multi-mode cold-press welding fixture ensures airtightness, each subsequent part requires reloading and transfer to the cold-press welding position, resulting in numerous loading and transfer steps and reduced processing efficiency. Furthermore, existing multi-mode cold-press welding fixtures for through-hole crystal oscillators are not universally compatible with different types of through-hole crystal oscillators, making it difficult to control the precision and stability of the processed crystals. Utility Model Content

[0004] The present invention aims to solve the above-mentioned problems and thereby provide a high-precision plug-in type crystal oscillator automated packaging system.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A high-precision automated packaging system for plug-in crystal oscillators includes a cold-press welding packaging module for cold-press welding and packaging of plug-in crystal oscillator components. The system also includes a first vacuum pumping device, a transparent sealed box, an isolation chamber, a second vacuum pumping device, a gripping robot, a transmission platform, and a transmission system. The cold-press welding packaging module is located within the gripping robot's range of motion. The transmission system is fixedly connected to the transmission platform and includes a circulating guide rail, five material platforms, and five material trays. Each material tray is detachably mounted on its corresponding material platform. The material platforms are fixedly connected to the circulating guide rail. On the circular guide rail, the first to sixth workstations are set. The cold-press welding and packaging module and the gripping robot are installed in a transparent sealed box. The transparent sealed box is evacuated to a vacuum state by a first vacuum device. The fourth workstation is located in the transparent sealed box and within the range of motion of the gripping robot. The isolation chamber is evacuated to a vacuum state by a second vacuum device. The isolation chamber is covered on the transmission platform. The third, fifth and sixth workstations are located in the isolation chamber. The isolation chamber is connected to the transparent sealed box through a first opening and closing door. A second opening and closing door is set on the side of the isolation chamber away from the transparent sealed box.

[0007] Furthermore, the first to sixth workstations include an intermediate workstation, a gripping workstation, a loading workstation, an unloading workstation, and two transfer workstations. The first workstation is the unloading workstation, the second workstation is the loading workstation, and the fourth workstation is the gripping workstation. When the second opening and closing door is open, the third workstation is the intermediate workstation, and the fifth and sixth workstations are both transfer workstations. When the first opening and closing door is open, the fifth workstation is the intermediate workstation, and the third and sixth workstations are transfer workstations.

[0008] Furthermore, the material platform is connected to the circulating guide rail via a mounting boss.

[0009] Furthermore, multiple material stations are arranged in an array on the material tray, and plug-in crystal oscillator components are placed in the material stations.

[0010] Furthermore, the size of the material handling station is set according to the size of the plug-in crystal oscillator component.

[0011] Furthermore, the center position of the corresponding material station on each of the material trays is the same.

[0012] Furthermore, a positioning pin hole is provided on the material tray, and a positioning pin is fixedly connected to the material platform. The material tray and the material platform are positioned and connected through the positioning pin hole and the positioning pin.

[0013] Furthermore, a manual unloading platform and a manual loading platform are fixedly connected to the end of the transmission platform away from the transparent sealed box.

[0014] Furthermore, the vacuum level inside the transparent sealed box is greater than that inside the isolation chamber.

[0015] Furthermore, the plug-in crystal oscillator component is placed in the same material station both before and after packaging.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The high-precision plug-in crystal oscillator automated packaging system of this utility model continuously evacuates the internal space of the transparent sealed box and the isolation chamber through the first vacuum device and the second vacuum device, so as to form a vacuum gradient between the transparent sealed box and the isolation chamber, thereby ensuring the cleanliness inside the transparent sealed box.

[0018] This high-precision automated packaging system for plug-in crystal oscillators utilizes a gripping robot to encapsulate plug-in crystal oscillator components one at a time at a time. The positioning surfaces, cold-welding surfaces, and mold closing height of the plug-in crystal oscillator components are more easily and precisely ground, avoiding the problem of poor airtightness caused by inconsistent component thickness in traditional multi-mold packaging systems. Furthermore, the fourth station is within the gripping robot's operating range, allowing for continuous gripping and ensuring processing efficiency. The internal vacuum level of the plug-in crystal oscillator components packaged using this invention is improved, significantly increasing product stability and yield. The material tray of this invention can hold different types and sizes of plug-in crystal oscillator components, thus achieving universal packaging for various types and sizes. The mold size of this invention is small and compact, facilitating packaging in an ultra-high vacuum environment throughout the entire process.

[0019] This utility model's high-precision plug-in crystal oscillator automated packaging system improves processing accuracy and packaging efficiency by using a gripping robot for automatic loading and unloading.

[0020] This utility model's high-precision plug-in crystal oscillator automated packaging system uses an isolation chamber for transfer, which can reduce the time for vacuuming inside the transparent sealed box, improve the vacuum level of the packaging environment, improve the quality of crystal oscillator products, and increase packaging efficiency.

[0030] See appendix Figure 1-5This embodiment describes a high-precision plug-in crystal oscillator automated packaging system, including a cold-press welding packaging module 3. The cold-press welding packaging module 3 performs cold-press welding and packaging of plug-in crystal oscillator components. It also includes a first vacuum pumping device 1, a transparent sealed box 2, an isolation chamber 7, a second vacuum pumping device 8, a gripping robot 4, a transmission platform 19, and a transmission system. The cold-press welding packaging module 3 is located within the operating range of the gripping robot 4. The transmission system is fixedly connected to the transmission platform 19. The transmission system includes a circulating guide rail 13, five material platforms 9, and five material trays 10. Each material tray 10 is detachably mounted on a corresponding material platform 9. The material platforms 9 are fixedly connected to the circulating guide rail 13. On the guide rail 13, the circulating guide rail 13 is provided with first to sixth workstations. The cold-press welding and packaging module 3 and the gripping robot 4 are installed inside the transparent sealed box 2. The transparent sealed box 2 is evacuated to a vacuum state by the first vacuum device 1. The fourth workstation 16 is located inside the transparent sealed box 2 and within the range of motion of the gripping robot 4. The isolation chamber 7 is evacuated to a vacuum state by the second vacuum device. The isolation chamber 7 is covered on the transmission platform 19. The third workstation 15, the fifth workstation 14, and the sixth workstation 12 are all located inside the isolation chamber 7. The isolation chamber 7 is connected to the transparent sealed box 2 through the first opening and closing door 5. The isolation chamber 7 is provided with a second opening and closing door 6 on the side away from the transparent sealed box 2. Specifically, the specific structure of the cold-press welding and packaging module 3 is existing technology and will not be described in detail here.

[0031] This high-precision plug-in crystal oscillator automated packaging system continuously evacuates the internal space of the transparent sealed box and the isolation chamber through a first vacuum device and a second vacuum device, creating a vacuum gradient between the transparent sealed box and the isolation chamber, thereby ensuring the cleanliness inside the transparent sealed box. The system uses a gripping robot to grip and package plug-in crystal oscillator components one at a time from each material station. The positioning surface, cold solder surface, and mold closing height of the plug-in crystal oscillator components are easier to precisely grind, avoiding the problem of poor airtightness caused by inconsistent component thickness in traditional multi-mode packaging systems. Simultaneously, the fourth station is within the gripping robot's range of motion, allowing the robot to grip continuously, thus ensuring processing efficiency. The internal vacuum level of the plug-in crystal oscillator components packaged using this invention is improved, significantly increasing product stability and yield. The mold size is small and the structure is compact, facilitating packaging in an ultra-high vacuum environment throughout the entire process. This application utilizes a gripping robot 4 for automatic loading and unloading, improving gripping accuracy and packaging efficiency. The use of an isolation chamber 7 for transfer reduces the time required for vacuuming the transparent sealed box 2, increasing the vacuum level of the packaging environment, improving crystal oscillator product quality, and enhancing packaging efficiency. The material tray of this invention can hold different types and sizes of plug-in crystal oscillator components, thus achieving universal packaging for various types and sizes of plug-in crystal oscillator components.

[0032] The first to sixth workstations include an intermediate workstation, a gripping workstation, a loading workstation, an unloading workstation, and two transfer workstations. The first workstation 11 is the unloading workstation, the second workstation 17 is the loading workstation, and the fourth workstation 16 is the gripping workstation. When the second opening and closing door 6 is open, the third workstation 15 is the intermediate workstation, and the fifth workstation 14 and the sixth workstation 12 are both transfer workstations. When the first opening and closing door 5 is open, the fifth workstation 14 is the intermediate workstation, and the third workstation 15 and the sixth workstation 12 are transfer workstations.

[0033] The material platform 9 is connected to the circulation guide rail 13 via mounting boss 23. The detachable connection between the material tray 10 and the material platform 9 allows the material tray 10 to be removed from the material platform 9 without stopping the circulation guide rail 13, and allows plug-in crystal oscillator components to be loaded onto the material tray 10. The mounting boss 23 connects the material platform 9 to the circulation guide rail 13, increasing connection stability.

[0034] Multiple material stations 18 are arranged in an array on the material tray 10, and plug-in crystal oscillator components are placed in the material stations 18. The multiple material stations 18 enable the plug-in crystal oscillator components installed at one time to meet the multiple packaging of the cold-press welding packaging module 3, reducing the workload of loading personnel. At the same time, by setting up the material stations 18, the position of the plug-in crystal oscillator components on the material tray 10 is fixed, ensuring that the gripping robot 4 accurately grips them, thereby improving the packaging stability of the high-precision plug-in crystal oscillator automated packaging system.

[0035] The material trays 10 are available in different models, and the material stations 18 on the different models of material trays 10 are set to different sizes according to the different sizes of plug-in crystal oscillator components. Setting the material stations 18 to different sizes improves the accuracy of manual assembly of plug-in crystal oscillator components, and ensures the packaging accuracy of the subsequent cold-press welding packaging module 3.

[0036] The size of the material handling station 18 is set according to the size of the plug-in crystal oscillator component. Setting the material handling station 18 to different sizes improves the accuracy when manually assembling the plug-in crystal oscillator component, and provides a guarantee for the packaging accuracy of the subsequent cold-press welding packaging module 3.

[0037] The center position of the corresponding material station 18 on each material tray 10 is the same. By unifying the center position of the corresponding material station 18 on each material tray 10, it is possible to replace the material tray 10 without changing the control program of the gripping robot 4 and the circulating guide rail 13, and at the same time, it is not necessary to replace the material table 9, thus simplifying the operation process.

[0038] The material tray 10 has a positioning pin hole 20, and the material platform 9 is fixed with a positioning pin. The material tray 10 and the material platform 9 are positioned and connected through the positioning pin hole 20 and the positioning pin.

[0039] The end of the transmission platform 19 furthest from the transparent sealed box 2 is fixed to a manual unloading platform 21 and a manual loading platform 22. Specifically, the worker is positioned between the manual loading platform 22 and the manual unloading platform 21 to load materials into the material tray 10 of the second workstation 17 and unload materials into the material tray 10 of the first workstation 11.

[0040] The vacuum level inside the transparent sealed box 2 is greater than that inside the isolation chamber 7. The transparent sealed box 2 is the main packaging area, hence the greater vacuum level inside it compared to the isolation chamber 7. This results in a higher negative pressure inside the transparent sealed box 2, preventing dust from the isolation chamber 7 from drifting into it and ensuring cleanliness. Simultaneously, the second vacuum device 8 creates a negative pressure buffer zone in the isolation chamber 7, reducing the amount of air entering the transparent sealed box 2 when the first opening door 5 is opened. This reduces the vacuuming time inside the transparent sealed box 2, enabling rapid opening of the cold-pressed welding packaging module 3 for packaging plug-in crystal oscillator components and improving processing efficiency.

[0041] The plug-in crystal oscillator components are placed in the same material station 18 before and after packaging. By placing the plug-in crystal oscillator components in the same material station 18 before and after packaging, it is possible to prevent the gripping robot 4 from missing or grabbing the packaged plug-in crystal oscillator components again into the cold-press welding packaging module 3.

[0042] The present invention discloses a high-precision plug-in crystal oscillator automated packaging system. The specific working steps are as follows: A first vacuum device 1 evacuates the transparent sealed box 2 to a vacuum state; a second vacuum device 2 evacuates the isolation chamber 7 to a vacuum state. Pre-assembled plug-in crystal oscillator components are manually placed on the material tray 10 at the second station 17. The second opening / closing door 6 is opened. The material trays 10 at the fifth station 14, sixth station 12, first station 11, and second station 17 move synchronously with the corresponding mounting bosses 23. While the pre-assembled plug-in crystal oscillator components are being transferred to the third station 15, the material tray 10 in the second station 17 is refilled with pre-assembled plug-in crystal oscillator components. The second opening / closing door 6 is then closed, and the system awaits isolation. When the vacuum level inside chamber 7 reaches the preset vacuum level, the first opening and closing door 5 is opened. The fourth station 16 moves to the fifth station first, and the third station 15 moves to the fourth station 16. The gripping robot 4 grips the material according to the center position of the material station 18 and packages the plug-in crystal oscillator component through the cold pressure welding and packaging module 3. During the packaging process, the pre-assembled plug-in crystal oscillator component in the second station 17 is transferred to the third station 15 again. After the packaging is completed, the first opening and closing door 5 is opened, and the packaged plug-in crystal oscillator component is transferred to the fifth station 14. At the same time, the material tray 10 containing the pre-assembled plug-in crystal oscillator component in the third station 15 is transferred to the fourth station 16 for cold pressure welding and packaging. This cycle continues.

[0043] Obviously, the above-disclosed embodiments of the present invention are merely for illustrating the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to specific implementations. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. It is neither necessary nor possible to exhaustively describe all implementation methods here.
