[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] A protective structure for a semiconductor module transfer stacker, such as Figures 1-5 As shown, the system includes a stacker crane 1, a conveyor 2, a cover 3, a proximity sensor 4, a buckle 5, a housing 6, uprights 61, a photoelectric sensor 7, a support block 8, a partition 9, an upper protective shell 10, and a lower protective shell 11. The stacker crane 1 has a built-in controller. The conveyor 2 is located on the upper inner side of the stacker crane 1. The semiconductor modules pass through the conveyor 2 and are finally stacked on top of the stacker crane 1. Four uprights 61 are connected to the top of the stacker crane 1. The four uprights 61 are vertically arrayed on the top of the stacker crane 1. The two uprights 61 on the left and the two uprights 61 on the right are connected to the stacker crane 1. Each of the two partitions 9 is connected to the top and extends outward from the stacker crane 1. The two partitions 9 are symmetrically arranged front and back, and the distance between the two partitions 9 is less than the width of the semiconductor module. A lower protective shell 11 is connected to each of the left and right partitions 9. An upper protective shell 10 is slidably connected to the top of each lower protective shell 11. The height of the upper protective shell 10 and the lower protective shell 11 relative to the conveyor 2 is greater than the height of the semiconductor module to ensure that the semiconductor will not collide with the upper protective shell 10 and the lower protective shell 11 during transport. A support block 8 is connected to the top of each partition 9. Each support block 8 has a photoelectric sensor 7 connected to its top. There are four photoelectric sensors 7: two at the front are receivers, and two at the rear are transmitters. The photoelectric sensors 7 are electrically connected to the controller on the stacker crane 1. The front ends of the two front columns 61 and the rear ends of the two rear columns 61 are connected to housings 6. Each housing 6 has two parts, upper and lower. The lower housing 6 has a coverage height twice that of the upper housing 6. The upper housing 6 has a 90-degree bend at its top. A clip is connected to the top of the front housing 6. The buckle 5 and the snap 5 are connected to a proximity sensor 4. The sensing end of the proximity sensor 4 faces upward. The top of the rear housing 6 is hinged to a cover 3. When the cover 3 is flipped down and contacts the front housing 6, it will contact the sensing end of the proximity sensor 4. The cover 3, housing 6, partition 9, upper protective housing 10 and lower protective housing 11 are all made of stainless steel. The conveyor 2 and the proximity sensor 4 are electrically connected to the controller on the stacker crane 1. When the proximity sensor 4 and the photoelectric sensor 7 receive a signal, they will control the stacker crane 1 to temporarily stop working through the controller.

[0021] When the operator uses the stacker 1 to work, first, the power supply of the stacker 1 is turned on, the proximity sensor 4 connected to the top shell 6 of the stacker 1 and the photoelectric sensor 7 connected to the top of the support block 8 are also powered on, when the operator opens the cover 3 upward from the shell 6, the cover 3 is separated from the proximity sensor 4, the proximity sensor 4 feeds back a signal to the controller, the controller controls the stacker 1 and the conveyor 2 to stop working, and the operator can easily take out the semiconductor module inside the four columns 61, avoiding the hand injury caused by the movement of the equipment when taking out the semiconductor module, after taking out the semiconductor module, the cover 3 is closed, the cover 3 contacts the proximity sensor 4, the controller controls the stacker 1 and the conveyor 2 to be powered on, and the equipment can continue to work, at the same time, the shell 6 can effectively limit the working area of the operator, avoiding dangerous events caused by the operator putting his hand into the inside of the stacker 1.

[0022] Since the distance between the front and rear two partitions 9 is less than the width of the semiconductor module, the semiconductor module cannot be taken out from the left and right sides of the stacker 1, and the photoelectric sensor 7 on the top of the partition 9 can sense the passing object, when the object or human body passes through the sensing area between the photoelectric sensor 7, the photoelectric sensor 7 feeds back a signal to the controller of the stacker 1 in time, the controller controls the stacker 1 and the conveyor 2 to stop working, further, avoiding the safety accidents caused by the movement of the equipment to the hand injury of the personnel.

[0023] The upper protection shell 10 and the lower protection shell 11 can also flexibly form a protection area, the upper protection shell 10 can slide on the lower protection shell 11 to the range to be protected, and the range protected by the protection shell can be flexibly adjusted, so that the operator cannot put his body in the stacker 1, avoiding the dangerous events caused thereby.

Any equivalent replacement made within the principles of the present application shall be included in the protection scope of the present application. The contents not described in detail in the present application belong to the prior art known by the technical personnel in the field.
