Description

Technical Field

[0001] The utility model belongs to the technical field of material flow storage and loading, and particularly relates to a material rack for facilitating the taking of IC packages. Background Art

[0002] IC packaging refers to connecting the circuit pins on the silicon wafer to the external joints with wires for connection to other devices. The packaging form refers to the housing used to install semiconductor integrated circuit chips. It not only plays roles in aspects such as installation, fixation, sealing, protection of the chip, and enhancement of electrothermal performance, but also connects the contacts on the chip to the pins of the packaging housing through wires, and these pins are further connected to other devices through the wires on the printed circuit board, thereby realizing the connection between the internal chip and the external circuit. Since the chip must be isolated from the outside to prevent the corrosion of the chip circuit by impurities in the air, which may cause a decline in electrical performance, a shelf is a storage device based on the six basic functions of packaging, transportation, loading and unloading, sorting, and information management in production logistics.

[0003] After retrieval, it is found that an IC tray storage rack disclosed in the patent with the publication number CN206520965U includes two vertical beams. Encapsulation components are provided between the upper and lower ends of the two beams. Both ends of the encapsulation component are respectively fixedly connected to the beams through locking parts to form an integral frame structure; several layers of bearing beam frames are provided between the two beams, and side hanging plates are connected between the two ends of the bearing beam frame and the beams. Several partition plates are arranged at intervals on the bearing beam frame; the structure of the utility model is reasonable. The storage rack is assembled from beams, an encapsulation structure, and bearing beam frames. Each component is a detachable structure, and the connection method uses the cooperation of lock holes and fasteners. The side hanging plates can be fixed at any floor height of the beam, so that the floor height can be quickly adjusted, which is convenient for the transportation, installation, disassembly, and adjustment of the storage rack; the spaced support tubes form a transparent bearing beam frame, and the partition plates can arbitrarily divide the floor width, which is convenient for the fixed storage of IC trays and is also beneficial to the fire extinguishing efficiency of fire-fighting equipment.

[0004] This patent can store IC trays, but the IC trays need to be kept sealed and dust-proof during the storage process. The storage rack of this patent is open, and dust is easily contaminated on the IC trays during the storage process. The materials used in IC packaging are IC chips after grinding and cutting, and due to the relatively high height of the storage rack, it is not convenient to take and store the IC materials at high places. Therefore, an IC placement storage rack with sealed storage and automatic taking is needed.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Utility Model

[0006] In order to solve the above problems, the purpose of the utility model is to provide a material rack for hermetically storing IC wafers and automatically storing them.

[0007] To achieve the above object, the present utility model provides a material rack for facilitating the taking of IC packages, including a material box. A storage rack is fixedly installed on the inner surface of the material box. An IC automatic access mechanism is fixedly installed in the inner cavity of the material box. The IC automatic access mechanism includes a lifting motor, a lifting threaded shaft, a moving frame, a fixed frame, a moving motor, a moving threaded shaft, a sliding rod, and a storage box. Transmission mechanisms are fixedly installed on the inner surfaces of the storage box and the storage rack. The transmission mechanism includes a conveyor belt, a bidirectional motor, a bidirectional rotating shaft, and a transmission wheel. A shielding plate is rotatably installed on the front of the material box through a hinge. An IC storage box is drivingly installed on the top of the conveyor belt.

[0008] In one example, the output end of the lifting motor is fixedly connected to the outer surface of the lifting threaded shaft through a speed reducer. The outer surface of the lifting threaded shaft is threadedly connected to the inner surface of the moving frame.

[0009] In one example, the top of the moving frame is fixedly connected to the bottom of the fixed frame. The inner surface of the fixed frame is fixedly connected to the outer surface of the moving motor.

[0010] In one example, the output end of the moving motor is fixedly connected to the outer surface of the moving threaded shaft through a speed reducer. The outer surface of the moving threaded shaft is threadedly connected to the inner surface of the storage box.

[0011] In one example, the top of the moving frame is fixedly connected to the outer surface of the sliding rod through a connecting frame. The outer surface of the sliding rod is slidably connected to the inner surface of the storage box.

[0012] In one example, the inner surface of the conveyor belt is drivingly connected to the outer surface of the transmission wheel. The output end of the bidirectional motor is fixedly connected to the outer surface of the bidirectional rotating shaft through a speed reducer.

[0013] In one example, the outer surface of the bidirectional rotating shaft is fixedly connected to the inner surface of the transmission wheel.

[0014] The material rack for facilitating the taking of IC packages proposed by the present utility model can bring the following beneficial effects:

[0015] 1. By adding a design for automatically taking the IC storage box at a high position of the material rack, the lifting motor drives the lifting threaded shaft to rotate. The lifting threaded shaft drives the fixed frame and the sliding rod to move through the moving frame. The fixed frame and the moving motor are used in cooperation. The moving motor drives the storage box to move through the moving threaded shaft, so as to move the storage box to the front of the storage rack at different heights and different positions. Then, through the mutual cooperation of the two transmission mechanisms in the storage rack and the storage box, the IC storage box can be automatically accessed and stored.

[0016] 2. The utility model designs a sealed and pollution-free storage method by adding IC wafers or IC trays. Through the combined use of the material box and the baffle, as well as the combined use of the storage rack, conveyor belt and IC storage box, the IC wafers can be stored without contacting external dust, thus avoiding the problem that the IC wafers are contaminated and cannot be used as much as possible.

[0029] Such as Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a material rack for facilitating the taking and placing of IC packages, which includes a material box 1. A storage rack 2 is fixedly installed on the inner surface of the material box 1. An IC automatic access mechanism 3 is fixedly installed in the inner cavity of the material box 1.

[0030] As Figure 1 shown, there is a layer of sealed transparent glass on the inner surface of the material box 1, which can observe the internal situation from the outside of the material box 1. At the same time, there is a control panel on the front surface of the material box 1, which can control the storage box 38 to move to different heights and different positions of the storage rack 2, so as to facilitate the access of the IC storage box 6 in the material box 1. The IC storage box 6 contains cut IC wafers, effectively avoiding external dust pollution of the IC wafers.

[0031] Specifically, as Figures 1 - 3 shown, the output end of the lifting motor 31 is fixedly connected to the outer surface of the lifting threaded shaft 32 through a speed reducer, and the outer surface of the lifting threaded shaft 32 is threadedly connected to the inner surface of the moving frame 33.

[0032] Specifically, as Figures 1 - 3 shown, the top of the moving frame 33 is fixedly connected to the bottom of the fixed frame 34, and the inner surface of the fixed frame 34 is fixedly connected to the outer surface of the moving motor 35.

[0033] As Figures 1 - 3 shown, there are two lifting motors 31 and two lifting threaded shafts 32. The two lifting motors 31 work together to enable the moving frame 33 on the lifting threaded shaft 32 to move up and down;

[0034] Among them, as an implementable method, it is also possible to directly drive one lifting threaded shaft 32 by one lifting motor 31 and drive the other lifting threaded shaft 32 through a belt at the same time; similarly, the moving frame 33 can also be displaced up and down, which is more energy-saving.

[0035] Specifically, as Figures 1 - 3 shown, the output end of the moving motor 35 is fixedly connected to the outer surface of the moving threaded shaft 36 through a speed reducer, and the outer surface of the moving threaded shaft 36 is threadedly connected to the inner surface of the storage box 38.

[0036] Specifically, as Figures 1 - 4As shown in the figure, the top of the moving frame 33 is fixedly connected to the outer surface of the sliding rod 37 through a connecting frame, and the outer surface of the sliding rod 37 is slidably connected to the inner surface of the storage box 38.

[0037] Specifically, as Figure 4 and 5 shown in the figure, the inner surface of the conveyor belt 41 is drivingly connected to the outer surface of the driving wheel 44, and the output end of the bidirectional motor 42 is fixedly connected to the outer surface of the bidirectional rotating shaft 43 through a speed reducer.

[0038] Specifically, as Figure 4 and 5 shown in the figure, the outer surface of the bidirectional rotating shaft 43 is fixedly connected to the inner surface of the driving wheel 44.

[0039] Working principle: The lifting motor 31 drives the lifting screw shaft 32 to rotate. The lifting screw shaft 32 drives the fixed frame 34 to move through the moving frame 33. The fixed frame 34 drives the moving screw shaft 36 to move through the moving motor 35. The moving screw shaft 36 drives the storage box 38 to move. The storage box 38 is moved in front of the baffle 5. Then the user opens the baffle 5, places the loaded IC storage box 6 on the conveyor belt 41 of the storage box 38, then closes the baffle 5 again. Then the lifting motor 31 is started to move the storage box 38 to the height on the storage rack 2 at a suitable position. Then the moving motor 35 drives the moving screw shaft 36 to rotate, and the moving screw shaft 36 drives the storage box 38 to move horizontally, so that the storage box 38 is moved to the blank position on this layer of the storage rack 2. Then the bidirectional motor 42 drives the driving wheel 44 to rotate through the bidirectional rotating shaft 43, and the driving wheel 44 drives the conveyor belt 41 to rotate, so that the IC storage box 6 is moved to the conveyor belt 41 on the storage rack 2 to store the IC storage box 6. When it is necessary to take out the IC storage box 6, the bidirectional motor 42 in the storage rack 2 drives the driving wheel 44 to rotate through the bidirectional rotating shaft 43, the driving wheel 44 drives the conveyor belt 41 to rotate, and the conveyor belt 41 drives the IC storage box 6 to move to the conveyor belt 41 on the storage box 38. Then the storage box 38 moves downward, so that the staff takes out the IC storage box 6 from the baffle 5.
