Description

Technical Field

[0001] The present invention relates to the technical field of graphite boat loading and unloading sheet applications, in particular to a dual-channel graphite boat loading and unloading sheet integrated machine. Background Art

[0002] At present, due to the extremely rich reserves of silicon in the earth's crust and the excellent electrical and mechanical properties of crystalline silicon solar cells compared to other solar cells, crystalline silicon solar cells occupy an important position in the photovoltaic field. When coating the surface of silicon wafers, the uncoated silicon wafers need to be inserted into the graphite boat of the PECVD vacuum coating equipment. Generally, the front or back side is coated first. After coating one side, the silicon wafer is taken out of the graphite boat by an automatic loading and unloading machine, turned over and coated on the other side. The separate coating of the front and back sides leads to a long production cycle and high production costs.

[0003] When using a traditional graphite boat, the processed product needs to be placed in the graphite boat for fixation, and the graphite boat is constantly installed and disassembled, which will cause friction to the graphite boat. Long-term friction will cause damage to the graphite boat and the product. At the same time, it needs to be replaced, which increases the cost. Therefore, the present invention proposes a dual-channel graphite boat loading and unloading machine. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dual-channel graphite boat loading and unloading integrated machine. By arranging a protective clamping component on the internal connection of the graphite boat, it is possible to stabilize the internal products when they are placed, reducing the friction on the surrounding graphite and thus causing damage. At the same time, it is convenient to disassemble and replace the locking stabilization component in the later stage, thereby improving work efficiency.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a dual-channel graphite boat loading and unloading integrated machine, comprising two fixed plates, wherein first tie rods are evenly provided through the two fixed plates, and multiple first tie rods are provided through multiple graphite plates, and multiple second tie rods are symmetrically provided through the multiple graphite plates near the end surfaces, and the multiple first tie rods respectively pass through multiple partitions;

[0006] A clamping assembly is provided inside each of the multiple partitions, and the clamping assembly includes a limit plate, the side walls of the limit plate are evenly fixedly connected with multiple positioning rings, the inner walls of the multiple positioning rings are threadedly connected with springs, the side walls of the limit plate away from the positioning rings are evenly fixedly connected with multiple connecting columns, the end faces of the multiple connecting columns are fixedly connected with clamping blocks, and the reaction force of the spring is used to make the limit plate drive the multiple connecting columns to move, thereby driving the clamping blocks to move, and finally clamping and fixing the products placed therein.

[0007] Both of the second pull rods are penetrated by a spacer, and the plurality of spacers are alternately distributed with the plurality of graphite plates.

[0008] The above technical solution facilitates connection and fixation at the end face, thereby facilitating the use of the entire device.

[0009] The two second pull rods pass through the two fixing plates near the end surfaces and are fixed by locking nuts.

[0010] The above technical solution is used to install and fix the fixing plate and the graphite plate.

[0011] The plurality of partitions are symmetrically provided with through holes near the top and the bottom, and the plurality of first pull rods pass through the partitions respectively through the through holes.

[0012] The above technical solution facilitates the installation and fixing of the partition frame.

[0013] The end surfaces of the plurality of springs away from the limiting plate are respectively arranged to be tightly fitted with the inner side walls of the partition frame.

[0014] The above technical solution facilitates the positioning of the spring, thereby utilizing the spring's force to perform clamping movement.

[0015] The plurality of connecting posts respectively penetrate the opposite side walls of the partition frame and are smoothly fitted therewith.

[0016] The above technical solution facilitates driving the clamping block to press and clamp the placed product.

[0017] The plurality of clamping blocks are all arranged in a semi-cylindrical shape.
