Abstract
Description
Technical Field
[0001] The utility model relates to the field of semiconductors, in particular to a reflection baffle clamp for an automatic material handling system of semiconductor wafers. Background Technique
[0002] The automatic material handling system (AMHS) of semiconductor wafers is a key technology in semiconductor manufacturing. It is responsible for automatically handling materials on the production line and consists of both software and hardware. The hardware mainly includes handling equipment such as overhead hoists (OHT), autonomous mobile robots (AMR), conveyors, etc., as well as storage equipment such as clean stockers, overhead buffer positions (OHB), and workstations. The software includes a material control system (MCS) and an equipment layer control system, which are responsible for overall scheduling and optimization. The AMHS system is crucial for improving the production efficiency and product yield of the wafer fab.
[0003] The application of the AMHS system in semiconductor wafer manufacturing also includes improving space utilization and reducing the idle time of machines. The overhead hoist system has become a standard configuration. During the daily high-altitude operation of the overhead hoist system, the hanging baffle is the most commonly used safety auxiliary tool, and its performance directly affects the safety of high-altitude operations. The main functions of the hanging baffle include:
[0004] 1. Ensure the correct positioning of the wafer: The reflection baffle may be used to help sensors and cameras more accurately identify and position the wafer, ensuring accuracy during the handling process.
[0005] 2. Prevent wafer collisions: During the movement of the wafers, the reflection baffle may be used to prevent contact and collision between the wafers, protecting the wafers from damage.
[0006] 3. Maintain the handling path: In an automated handling system, the reflection baffle may be part of the path, guiding the wafer to move along a predetermined path.
[0007] The top clamp of the existing hanging baffle telescopic rod is made of acrylic, with a short service life and prone to breakage. For example, when passing through the reflection baffle (blocking the overhead hoist), the breakage of the clamp will cause the reflection baffle to fall off the track, and the overhead hoist will hit construction workers or other obstacles, resulting in failures of the track or the overhead hoist, posing a great safety hazard. The existing hanging baffle telescopic rod cannot ensure construction safety during use and needs to be improved. Summary of the Utility Model
[0008] A series of simplified concepts are introduced in the utility model content section. These simplified concepts are simplified from the existing technologies in the field, which will be further elaborated in the detailed implementation section. The utility model content section of the present utility model does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.
[0009] The technical problem to be solved by the present utility model is to provide a reflective baffle fixture with durability and convenience in use.
[0010] To solve the above technical problem, the reflective baffle fixture provided by the present utility model is used for an automatic material handling system of semiconductor wafers and includes:
[0011] A telescopic rod 1, one end of which is connected to a connecting portion 3 of a chuck 2;
[0012] The chuck 2 includes: a connecting portion 3, a supporting portion 4 and an elastic portion 5;
[0013] The connecting portion 3 is formed at the lower end of the supporting portion 4;
[0014] The elastic portion 5, the lower part of which is fixedly connected to the lower part of the supporting portion 4, is used for inserting into the connection port of the reflective baffle;
[0015] In a non-loaded state, there is always a gap between the upper part of the elastic portion 5 and the upper part of the supporting portion 4, and this gap is beneficial for the elastic portion 5 to insert into the connection port of the reflective baffle.
[0016] Preferably, further improving the reflective baffle fixture, the telescopic rod 1 is made of thermoplastic or metal. Since the telescopic rod is not a contact component of the reflective baffle, it can be made into a relatively large size. Therefore, by using thermoplastic such as acrylic, sufficient strength can be provided while ensuring overall light weight.
[0017] Preferably, further improving the reflective baffle fixture, it is a single-section telescopic rod, a multi-section inner telescopic rod, a multi-section outer telescopic rod, a spring telescopic rod, a locking telescopic rod or a folding telescopic rod.
[0018] Single-section telescopic rod: This kind of telescopic rod is usually composed of a long rod and can adjust its length by telescoping.
[0019] Multi-section inner telescopic rod: It is composed of multiple rods, and the inner rods can be inserted into the outer rods, and the length can be adjusted by rotation or pulling.
[0020] Multi-section outer telescopic rod: Similar to the inner telescopic rod, but the rod sections are connected and locked externally.
[0021] Spring telescopic rod: It has a built-in spring mechanism and can adjust the length of the rod by compressing or releasing the spring.
[0022] Locking telescopic rod: The telescopic rod is fixed at a specific length through a rotation or button locking mechanism.
[0023] Folding telescopic rod: The structure allows the rod to be folded up for easy carrying and storage.
[0024] Preferably, further improve the reflection baffle clamp. The connecting portion 3 is formed with an internal thread, which cooperates with the external thread at the connecting end of the telescopic rod 1 to form a fixed connection. With this design, when the chuck 2 is damaged, the chuck 2 can be directly replaced, and the telescopic rod 1 can be reused.
[0025] Preferably, further improve the reflection baffle clamp. The connecting portion 3, the supporting portion 4 and the elastic portion 5 are made of metal. Correspondingly, since the elastic portion 5 needs to be inserted into the reflection baffle, its size is limited by the size of the connection port. The connecting portion 3, the supporting portion 4 and the elastic portion also need to bear the weight of the reflection baffle. Therefore, the present utility model is made of metal, such as stainless steel.
[0026] Preferably, further improve the reflection baffle clamp. The supporting portion 4 is formed into a plate-like structure, and the elastic portion 5 is formed into a plate-like structure adapted to the shape of the supporting portion 4.
[0027] Preferably, further improve the reflection baffle clamp. At least the upper end portion of the elastic portion 5 is formed into a guiding structure, and the purpose of designing the guiding structure is to facilitate the insertion into the connection port of the reflection baffle.
[0028] Preferably, further improve the reflection baffle clamp. The width of the upper end portion of the elastic portion 5 gradually increases from small to equal to the width of the supporting portion 4.
[0029] Preferably, further improve the reflection baffle clamp. The upper end portion of the elastic portion 5 is a triangular structure with a chamfer formed at the apex position.
[0030] The present utility model can at least achieve the following technical effects:
[0031] 1. The chuck of the present utility model is made of metal material, which ensures the safety factor of track climbing operation, basically eliminates the situation of OHT & track damage caused by fixture damage, reduces the maintenance manpower, significantly improves the working efficiency of climbing operation, and has a great positive effect on the smooth progress of the whole production.
[0032] 2. In the non-loaded state, there is always a gap between the upper part of the elastic portion 5 and the upper part of the supporting portion 4 of the present utility model, which is beneficial to the insertion of the elastic portion into the connection port and can improve the operation convenience.
[0033] Furthermore, setting the guiding structure is also beneficial to improving the operation convenience.
[0034] 3. The chuck and the telescopic rod of the present utility model form a modular structure, which can be replaced separately, reducing the usage cost and improving the convenience of use. For example, the same telescopic rod can be used in combination with different chucks.
[0035] 4. The present utility model is solid and durable, and is not only suitable for hanging reflection baffles, but also can be used as an auxiliary tool for track maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
