Description

Vibration table device for assisting graphite boat battery piece placing

Technical Field

The utility model relates to a supplementary graphite boat battery piece puts shaking table device of piece specifically is a shaking table device based on piece, uneven and fish tail of coating film when putting into the graphite boat, belongs to solar cell production technical field.

Background

In a cell production workshop, when a manipulator for coating a P tube puts wafers (silicon wafers) to a graphite boat in batches, the wafers are always placed improperly, so that uneven coating, scratching, wafer dropping and the like are caused, and the P tube coating manipulator is also a difficulty in the current photovoltaic industry. Along with the competition aggravation of the current photovoltaic industry, the intelligent photovoltaic industry is realized, and meanwhile, the common targets of improving the efficiency, reducing the cost and improving the quality become numerous photovoltaic enterprises. In the prior art, the upper surface of the graphite boat is beaten manually or automatically, so that the overall beating force is not in place, the expected effect cannot be achieved, or the graphite boat piece is damaged due to excessive beating force.

Disclosure of Invention

Utility model purpose: problem and not enough to exist among the prior art, the utility model provides a supplementary graphite boat battery piece puts shaking table device of piece takes mechanical vibration's principle, and when the graphite boat that fills with the silicon chip slowly passes through the shaking table face, the vibrating pump starts, and whole graphite boat will be along with the mesa vibration gets up. Therefore, the silicon wafer with the offset placement position can be slowly moved to a proper position, so that the phenomena of scratching due to large friction, damage of a boat due to large-force beating and wafer falling due to the offset position of the silicon wafer are effectively reduced.

The technical scheme is as follows: a vibration table device for assisting in placing graphite boat battery pieces comprises a vibration table, four ground feet, four supporting columns, a vibration pump, a conveying belt, a driving wheel and a conveying motor; the vibrating table is arranged on the four supporting columns; the lower end of the support column is connected with a ground pin; the supporting columns are sleeved with buffer springs, the buffer springs are arranged between the vibrating table and the ground feet, and the upper ends of the buffer springs are connected with the vibrating table and used for supporting the vibrating table; two driving wheels are arranged on the outer side of each end of two opposite ends of the vibrating table, a conveying belt is arranged on the two driving wheels at different ends, and a conveying motor drives the driving wheels; the conveying belt is sleeved on the vibration table and used for conveying the graphite boat; and the lower table surface of the vibration table is connected with a vibration pump.

The frequency of the vibration pump is between 0 and 50 Hz.

The vibration pump is turned on and off through a PLC control circuit.

The working process is as follows:

when feeding, a mechanical handle of the automatic feeding and discharging machine is used for conveying silicon wafers into a graphite boat, the graphite boat filled with the silicon wafers is firstly transmitted to a P film coating machine through a vibration table, when the graphite boat passes through the vibration table, a vibration pump starting signal is given through a PLC (programmable logic controller) control circuit, the vibration table drives the graphite boat to vibrate, the silicon wafers placed in the graphite boat in an offset manner are slowly moved to an optimal position, the graphite boat moves along with a conveyor belt, and when the graphite boat leaves the vibration table, the vibration pump is turned off and stops; during blanking, the graphite boat also reaches a blanking area through the conveying of the vibrating table, through vibration (vibration is not needed during blanking) during once feeding, silicon wafers in the graphite boat are in a relaxed state after being produced through the process of the tube P coating machine, the silicon wafers can be lightly sucked by the manipulator, and omission, scratches and the like are not prone to being caused.

The equipment involved in the engineering process comprises an automatic feeding and discharging machine, a vibration table device and a pipe P coating machine, wherein the vibration table device is a transmission and vibration device between the automatic feeding and discharging machine and the pipe P coating machine. During feeding, the graphite boat is fully filled with silicon wafers by an automatic mechanical handle of the automatic feeding and discharging machine, the silicon wafers are conveyed to the vibration table by a belt after being fully filled, at the moment, a vibration pump and a conveyor belt on the vibration table work simultaneously, and the vibration table stops vibrating and transmitting after the graphite boat reaches the pipe P coating machine through the vibration table; during blanking, the transmission belts are all operated in reverse directions, the graphite boat with the P-shaped coated silicon wafers is conveyed to an automatic loading and unloading machine through the same vibration table (note: in the process, the vibration pump stops working, vibration is not needed, the silicon wafers are in a relaxed state), the mechanical arm unloads the coated silicon wafers to the flower basket, and the like.

Description of structural components:

the vibration table device comprises a vibration table, a conveyor belt, a driving wheel, a conveying motor, a vibration pump, a buffer spring and the like. The conveying motor, the conveying belt and the driving wheel are used for conveying the graphite boat for feeding or discharging; the vibration pump plays a role of vibrating the graphite boat, so that the silicon wafers in the boat are reasonably placed; 4 buffer spring above the lower margin guarantee that the shaking table can vibrate more easily to the graphite boat also can shake, so as to reach anticipated effect.

Has the advantages that: compared with the prior art, the utility model provides a supplementary graphite boat battery piece puts shaking table device of piece reduces effectively that piece, fish tail and coating film are uneven phenomenon to improve product quality, also promoted efficiency.
