Description

Technical Field

[0001] This invention belongs to the field of semiconductor manufacturing auxiliary equipment technology, specifically relating to an automatic storage and dispatch cabinet for semiconductor products. Background Technology

[0002] A semiconductor molding process is disclosed, applied to the production of semiconductor molded products. Before production, the parts to be manufactured are stored, checked, and issued, allowing for subsequent processing. Semiconductor molding is a mature production process, primarily consisting of: a nitrogen cabinet, an automatic wafer stacker, an injection molding machine, MGP molds, an automatic runner punch, epoxy resin, and the products to be processed. The main working principle is to use the injection molding machine to encapsulate the epoxy resin with the product, primarily to prevent external environmental impact on the product's internal structure.

[0003] However, existing traditional nitrogen cabinets are box-type with compartments, and materials are manually placed, which has the following drawbacks: 1. Traditional nitrogen cabinets use flow meters for nitrogen filling, which cannot guarantee the temperature and humidity of the top and bottom compartments, leading to product oxidation; 2. The cabinet door opens and closes repeatedly, failing to isolate dust particles, easily contaminating products and causing separation; 3. The shelves in traditional nitrogen cabinets are hook-type, posing a risk of detachment, causing products to fall and become unusable; 4. Material handlers must manually place materials into the cabinets, making it difficult to maintain spacing between batches, easily leading to confusion and mixing of materials; 5. [Further issues may arise due to the lack of proper material handling and handling.] 6. Traditional nitrogen cabinets require manual placement of products by material handlers, which cannot guarantee the correct force applied by each person. Excessive force can cause vibration, leading to wire deformation and collapse. 7. Traditional nitrogen cabinets require manual placement of products by material handlers, increasing the risk of contact and potential wire collapse. 8. Traditional nitrogen cabinets require manual removal of products during processing, posing a risk of dropping. 9. Traditional nitrogen cabinets require operators to search for products according to production needs, increasing the risk of wire collapse and mixing. 10. Traditional nitrogen cabinets do not guarantee the first-in, first-out (FIFO) principle. Summary of the Invention

The discharge section includes a lead screw d, two circular guide rails c, lead screw fixing blocks b located at both ends of the lead screw d, a servo motor d corresponding to and connected to the lead screw d and the circular guide rails c, a lead screw stepper motor b, a servo motor e, a servo motor f, a motor coupling b, a lead screw nut c, a linear bearing d, a circular guide rail d, a lead screw e, a bearing d, a limit fixing block b, a linear bearing e, a linear bearing f, a bearing e, a synchronous pulley f, a lead screw f, a lead screw nut d, a photoelectric switch sensor e, a photoelectric switch sensor f, a synchronous belt c, a lead screw fixing block, a fixing block c, a gripper guard plate c, a photoelectric switch sensor g, a rubber buffer pad b, a material box detection probe b, a spring b, a probe fixing cover b, a photoelectric switch sensor h, a gripper guard plate d, a loading tray b, a rotating shaft b, a bearing f, a synchronous pulley g, a synchronous belt d, and a photoelectric switch sensor B; The servo motor d in the discharge section starts working, driving the entire discharge gripper section towards the designated cabinet compartment via motor coupling b, lead screw d, lead screw nut c, and lead screw fixing block b. Once the discharge gripper section reaches the designated cabinet compartment, the loading pallet b in the discharge section presses down the telescopic stop at the discharge point of the conveyor belt inside the cabinet. The servo motor g starts working, conveying the product box to the discharge gripper via the conveyor belt. Simultaneously, the servo motor e starts working, driving the rotating shaft b and synchronous belt d towards the gripper guard plate c via synchronous pulley and synchronous belt c. After the product box triggers the photoelectric switch sensor B, the servo motor e stops working, and the servo motor f starts working, driving the clamping support plate towards the product box via synchronous pulley, synchronous belt c, lead screw f, lead screw nut d, and lead screw nut fixing block. When the elastic buffer pad b presses against the product box, the pressure probe b of the product box detects pressure... Spring b triggers photoelectric switch sensor h, servo motor f stops working, lead screw stepper motor b controls lead screw e to rotate, driving fixed block c to move backward away from the conveyor belt outlet telescopic stop column of the cabinet. After triggering photoelectric switch sensor g, lead screw stepper motor b stops working, servo motor d starts working, driving the entire discharge gripper part to move towards the discharge set position through motor coupling b, lead screw d, lead screw nut c, and lead screw fixed block b. After the discharge gripper part reaches the set position, servo motor d stops working, servo motor f starts working, driving clamping support plate to move in the opposite direction to the product box through synchronous pulley, synchronous belt c, lead screw f, lead screw nut d, and lead screw nut fixed block. Clamping support plate, elastic buffer pad b, and box detection probe b disengage from the box, photoelectric switch sensor h is detrimentalized, and servo motor f stops working after clamping support plate reaches the set height.
