Technical Field
[0001] This utility model relates to the technical field of semiconductor manufacturing and processing equipment, and in particular to a semiconductor receiving device structure. Background Technology
[0002] Semiconductor manufacturing processes consist of wafer fabrication, wafer testing, chip packaging, and post-packaging testing. After molding, a series of operations are performed, such as post-mold curing, trimming and forming, plating, and printing. A typical packaging process flow is: dicing, die mounting, bonding, molding, deflashing, plating, printing, trimming and forming, visual inspection, finished product testing, and packaging and shipping.
[0003] In the semiconductor manufacturing process, semiconductors are packaged and mounted on PCBs. The copper traces on the PCBs enable interconnection between chips and power distribution. The assembled semiconductor PCBs are then stored, usually in storage boxes. The storage boxes filled with PCBs are placed in a buffer device. However, during the transportation of storage boxes, not all of them contain PCBs. Users usually have to visually inspect and manually remove the empty boxes, which increases the labor costs required for the production line. Utility Model Content

[0009] In a preferred embodiment of the semiconductor receiving device structure of this utility model, the empty box detection moving mechanism further includes a connecting frame, a second motor is fixedly installed at the bottom of the connecting frame via a connector, a second threaded shaft is fixedly installed at the output end of the second motor via a reducer, and a gripper is threaded on the outer surface of the second threaded shaft.
[0010] In a preferred embodiment of the semiconductor receiving device structure of this utility model, the gravity detector of the empty cell detection moving mechanism is fixedly connected at the bottom to the top of the base.
[0011] In a preferred embodiment of the semiconductor receiving device structure of this utility model, the PCB moving mechanism includes a placement frame, the bottom of which is fixedly connected to the bottom of the first transporter, a third motor is fixedly installed on the outer surface of the placement frame, and a rotating shaft is fixedly installed on the output end of the third motor through a reducer. The rear end of the rotating shaft passes through the placement frame and extends into the interior of the placement frame.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] 1. This utility model improves upon the design of detecting the empty movement of semiconductor PCB storage boxes by adding a mechanism for detecting empty boxes. This is achieved through the combined use of a first transporter and a gravity detector, a first motor and a first threaded shaft in conjunction with a moving frame and a connecting frame, and a connecting frame, a second motor, a second threaded shaft, and a gripper. This allows for the detection of whether the semiconductor PCB storage box is empty. After the semiconductor PCB storage box is filled with semiconductor PCBs, it is moved to a third transporter and stored in the buffer device, thus avoiding the problem of empty storage boxes being placed in the buffer device together with storage boxes filled with PCBs.
[0015] 2. This utility model improves upon the design of slowly placing the semiconductor PCB board into the storage box by using the placement rack and the first transporter in conjunction with the third motor and the rotating shaft, the rotating shaft and the chain teeth in conjunction with the toothed chain and the connecting rod, and the connecting rod and the pusher, thereby achieving the goal of slowly placing the semiconductor PCB board into the empty box on the gravity detector.

[0029] During use, the No. 1 motor 52 drives the No. 1 threaded shaft 53 to rotate. The No. 1 threaded shaft 53 drives the connecting frame 55 to move through the moving frame 54. The connecting frame 55 drives the No. 2 motor 56 to move. The No. 2 motor 56 drives the gripper 58 to move through the No. 2 threaded shaft 57, placing the empty box on the No. 2 transporter 3 onto the gravity detector 59.
[0030] Example 2
[0031] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the PCB moving mechanism 6 includes a placement frame 61. The bottom of the placement frame 61 is fixedly connected to the bottom of the first transporter 2. A third motor 62 is fixedly installed on the outer surface of the placement frame 61. The output end of the third motor 62 is fixedly installed with a rotating shaft 63 through a reducer.
