Description

Technical Field

[0001] The utility model relates to the technical field of dicing machines, in particular to a heating bottom plate of a dicing machine. Background Art

[0002] Laser scribers are generally used in the manufacturing process of solar panels. Laser scribers are used to separate the cells, which are then spliced ​​with different laminates to form solar panels.

[0003] When the laser scribing machine is dividing the battery cells, the battery cells are subjected to high-temperature ablation of the laser and cooling by the spray of cooling water mist, which generates alternating stress. Under the action of alternating stress, the battery cells will break. Due to the breakage, some silicon powder will be produced at the break of the battery cell, and a layer of water mist will be covered on the silicon powder. In the related art, a conveyor belt and an air knife are usually provided on the bottom plate of the laser scribing machine, and the bottom plate of the laser scribing machine will be automatically heated. In specific use, the divided battery cells are placed on the conveyor belt for transportation. During the transportation, the air knife will blow away the water mist and silicon powder. In addition, the bottom plate of the laser scribing machine will transfer heat to the battery cells through the conveyor belt, thereby evaporating the water mist covering the broken part of the battery cell. In order to ensure the stability of the battery cell during transportation, a hole is usually punched on the conveyor belt, and the suction fixing device on the bottom plate of the laser scribing machine passes through the hole to fix the battery cell on the conveyor belt.

[0004] However, in the above process, the heating base plate is prone to poor heat transfer after long-term use, which causes the temperature of the conveyor belt to drop, resulting in the inability to dry the water mist at the broken parts of the battery cells, thereby affecting the quality of the battery cells.

[0036] The inclined bottom surface 700 is inclined along the direction of the first through hole 300 .

[0037] like Figure 1-Figure 2As shown, the dicing machine heating base plate provided in the embodiment of the present application includes a plate body 100, wherein the plate body 100 can be the base plate of the laser dicing machine, and a conveyor belt is arranged above the plate body 100, and the conveyor belt is used to transport the battery cell to a designated location. In actual use, a plurality of through holes will be opened on the conveyor belt, and correspondingly, an air suction fixing device will be arranged on the plate body 100, and the air suction fixing device will absorb the battery cell on the conveyor belt through the through holes to ensure that the battery cell can be stably transported on the conveyor belt.

[0038] The plate body 100 includes an upper surface 110 and a side surface 120. A conveyor belt is disposed above the upper surface 110 of the plate body 100. Two grooves 200 are disposed on the upper surface 110 of the plate body 100. Each groove 200 extends along the thickness direction of the plate body 100, and the length of each groove 200 is equal to the length of the plate body 100. In this embodiment, the center line of the upper surface 110 is the axis of symmetry, and the two grooves 200 are symmetrically distributed on the upper surface 110 of the plate body 100.

[0040] In a specific implementation, by making the groove 200 on the plate body 100 correspond to the hole on the conveyor belt up and down, the silicon powder generated when the battery cell breaks will enter the groove 200 through the hole on the conveyor belt. Since the first through hole 300 is opened in the groove 200, the first through hole 300 is connected to the second through hole 400, and the second through hole 400 is connected to the outside, the silicon powder entering the groove 200 will enter the second through hole 400 through the first through hole 300 in turn.
