"The laser debonding device includes a stage for holding the to-be-debonded part thereon, and the to-be-debonded part includes a first layer structure and a second layer structure bonded by a bonding layer. It also includes a suction cup and a laser system. The suction cup is adsorbed on the surface of the second layer structure. The laser system is used to generate a laser beam that passes through the suction cup and the second layer structure in sequence and focuses on the bonding layer, and controls the focus of the laser beam to scan the bonding layer to debond the bonding layer. It also includes a stretching mechanism connected to the suction cup, which is used to pull the suction cup upward after the laser beam scans a partial area of the bonding layer, so that the first layer structure and the second layer structure are separated at a position overlapping with the partial area.

[0019] Preferably, the working steps of the stripping machine are as follows:
[0020] S1. When the processor detects that the temperature is too high, the processor controls the power of the heating ring to be reduced. At the same time, the temperature sensor continuously detects the built-in temperature data for the processor to judge. When the processor detects that the real-time temperature data is in a normal temperature state, the processor controls the heating ring to maintain the current power.

[0021] S2. The function of the L-shaped frame is to provide support for the No. 1 magnetic head. When the fan is started, the wind is filtered through the filter and then enters the wind receiving head. The wind is transported to the nozzle by the air duct. At the same time, the heating ring is started to heat the wind. After the wind is heated, it is sprayed to the surface of the cleaned wafer through the nozzle to make it dry quickly. The handle is pulled to move the filter, and the filter moves to move away from the No. 1 magnetic head. At this time, the filter pulls out the No. 1 support to facilitate cleaning, realizing the function of quickly drying the surface of the cleaned wafer by the wafer debonding and stripping machine to improve work efficiency.
[0022] S3. The inner wall of the collection box is provided with cleaning liquid. After the wafer is debonded, it is placed in the cleaning chamber and supported and adsorbed by pillars. The pillars are vacuum adsorption pillars. At this time, the water pump is started to suck the cleaning liquid into the No. 5 water pipe, and the water spray head is sprayed on the surface of the wafer to quickly clean it. The cleaning liquid after cleaning enters the No. 6 water pipe through the diversion effect of the guide block, and the cleaning liquid enters the collection box through the No. 6 water pipe. The cleaning liquid after cleaning passes through the dust filter net to filter the impurities in it. The filtered cleaning liquid falls to the bottom of the collection box for recycling. Pull the pull ring to make its slot remove the No. 6 magnetic block. The slot is made of iron. At this time, the movement of the pull ring drives the movement of the dust filter net. The movement of the dust filter net makes it move out of the collection box to facilitate the cleaning of stains, thereby realizing the function of recycling the cleaning liquid of the wafer debonding and stripping machine and reducing waste;
[0023] S4. The support rod moves through port No. 7. After the wafer is placed on the top of the vacuum suction cup, the cylinder starts to drive the support rod to move.

[0026] 2. The present invention provides support for the No. 1 magnetic head by installing an L-shaped frame. When the fan is started, the wind is filtered through the filter and then enters the wind receiving head. The wind is transported to the nozzle by the air duct. At the same time, the heating ring is started to heat the wind. After the wind is heated, it is sprayed to the surface of the cleaned wafer through the nozzle to make it dry quickly. The handle is pulled to drive the filter to move. The filter moves to move away from the No. 1 magnetic head. At this time, the filter pulls out the No. 1 support to facilitate cleaning, thereby realizing the function of quickly drying the surface of the cleaned wafer by the wafer debonding and stripping machine to improve work efficiency.
[0027] 3. The present invention is provided with a cleaning liquid on the inner wall of a collection box, and the wafer is placed in a cleaning chamber after debonding, and supported and adsorbed by a pillar, which is a vacuum adsorption column. At this time, the water pump is started to suck the cleaning liquid into the No. 5 water pipe, and the water spray head is sprayed on the surface of the wafer to quickly clean it. The cleaning liquid after cleaning enters the No. 6 water pipe through the diversion effect of the guide block, and the cleaning liquid enters the collection box through the No. 6 water pipe. The cleaning liquid after cleaning is filtered through the dust filter net. The filtered cleaning liquid falls into the bottom of the collection box for recycling.
