[0002] New energy photovoltaic battery components have developed rapidly in recent years. When producing its core component silicon wafers, due to the use of diamond wire cutting technology and the simultaneous lubrication of cutting fluid, it is necessary to carry out centralized and batch cleaning of the cut silicon wafers to remove as much as possible the silicon powder, gravel, oil and other impurities and pollutants remaining on the surface of the silicon wafers, so that the silicon wafers can meet the production process requirements of the battery components. The current mainstream silicon wafer cleaning process is implemented on an ultrasonic cleaning machine. The general process is to put the flower basket with silicon wafers into the silicon wafer cleaning tank, mix a certain concentration of chemical reagents in the cleaning tank, and use a circulating pump to make the chemical reagents flow continuously through the surface of the silicon wafer to achieve the cleaning purpose; in addition, ultrasonic vibration is generally used to enhance the above cleaning effect.

[0003] However, the cleaning speed is still slow when relying solely on the above two methods. The silicon powder impurities that fall off due to vibration are suspended between the silicon wafers and cannot be discharged in time. In addition, the relative movement speed between the silicon wafers and the water flow is low, and the residual silicon powder on the surface of the silicon wafer cannot fully react with the chemical reagents, resulting in low overall cleaning efficiency.

[0006] Preferably, linear bearings are provided on both sides of the first cleaning tank and the second cleaning tank, and the interiors of the first cleaning tank and the second cleaning tank are slidably connected to the surfaces of the linear bearings.

[0007] Preferably, the number of the gears is eight, four gears form a group, and a movable rod is rotatably connected between opposite sides of two gears.

[0008] Preferably, a support is fixedly connected to one side of the motor, and the output end of the motor passes through the support and extends to one side of the support.

[0023] Specifically, the first cleaning tank 1 and the second cleaning tank 7 have the same size, and the driving shaft 6 is arranged in the middle between the first cleaning tank 1 and the second cleaning tank 7 on opposite sides.

[0024] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0025] The existing technical scheme mainly consists of a cylinder 3, a lifting frame 7 and a silicon wafer carrier 8. The lifting frame 7 consists of a horizontally arranged connecting shaft 4 and vertical rods 6 arranged at both ends of the connecting shaft 4. The connecting shaft 4 is connected to the telescopic end of the piston rod of the cylinder 3, so that the lifting frame 7 can perform reciprocating lifting and lowering motion under the drive of the cylinder 3. A guide column 5 is respectively provided at the position corresponding to the two vertical rods 6. The vertical rod 6 is slidably arranged in the guide groove of the guide column 5 through a slider arranged on its side. The silicon wafer carrier 8 includes a bottom plate, a plurality of protrusions are provided on the bottom plate, and a card groove for placing a silicon wafer cleaning basket is formed between the plurality of protrusions and the bottom plate. A plurality of water-permeable holes are distributed on the bottom plate. Two connecting rods are respectively provided on both sides of the bottom plate. The top ends of the two connecting rods on the same side are connected by an ear plate, and the two ear plates are respectively connected to the top ends of the two vertical rods 6 of the lifting frame 7, so that the silicon wafer carrier 8 can move up and down in the cleaning tank of the silicon wafer cleaning machine under the drive of the lifting frame 7. For the specific principle, refer to Figure 3 ,

[0026] The existing washing machine shaking device has the following disadvantages:

[0027] 1. There is only one cylinder as the driving source. When the cleaning machine is filled with liquid and loaded with silicon wafers, its weight is relatively large. All the power is generated by the cylinder when it is working. The load is relatively large, which increases the failure rate of the cylinder.

[0028] 2. The power source is compressed air, which has high requirements on air pressure and increases the cost of facilities;

[0029] 3. The cylinder is located below the tank, which makes repair, maintenance and replacement inconvenient when a fault occurs.

[0030] Compared with the prior art, this solution realizes that two cleaning tanks share one driving motor 9. The same number of cleaning tanks can reduce the number of driving sources, reduce energy consumption and equipment costs, and move the power source to the side of the tank body to facilitate daily maintenance. The cleaning tanks on both sides serve as counterweights to each other, and can be driven to operate by overcoming the basic friction. The power and torque requirements of the driving motor 9 are reduced, which is beneficial to reducing energy consumption. The cleaning tank is subjected to force in the vertical direction, in the same direction as the linear bearing 2, and the overall force is reasonable. Compared with the mainstream throwing method, there is no torque wear load on the linear bearing 2, which is beneficial to extending its service life and reducing the equipment failure rate.

[0031] When in use, in the initial state, the first cleaning tank 1 and the second cleaning tank 7 deviate by a certain height in the vertical direction, and then the driving gear 5 changes the transmission direction of the chain 3 through the gear 8, and applies a vertical force to the first cleaning tank 1 and the second cleaning tank 7, driving the first cleaning tank 1 and the second cleaning tank 7 on both sides to make a linear motion in the opposite vertical direction. After the first cleaning tank 1 and the second cleaning tank 7 on both sides deviate by a certain height, the motor 9 slowly stops running and changes the direction of movement, so that the first cleaning tank 1 and the second cleaning tank 7 on both sides make an up and down throwing motion repeatedly. When the tank is filled with liquid, it reciprocates up and down with the tank body, thereby increasing the relative motion speed between the cleaning liquid and the surface of the silicon wafer, making it easier for impurities and foreign matter on the surface of the silicon wafer to fall off, thereby increasing the cleaning effect and further improving the cleaning efficiency.
