Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically relates to a front main grid pretreatment cleaning machine. Background Technology

[0002] In the production process of photovoltaic panels, it is usually necessary to print the main grid on the front side of the photovoltaic panel. When printing the main grid, it is necessary to ensure the cleanliness of the photovoltaic panel surface, which requires cleaning the photovoltaic panel in advance. At present, the cleaning of photovoltaic silicon wafers is generally carried out by ultrasonic cleaning tank. The photovoltaic silicon wafer is placed in a collection basket, and the collection basket is placed in the cleaning tank for ultrasonic cleaning. However, traditional ultrasonic cleaning tanks have certain problems in use. For example, when the collection basket and the photovoltaic silicon wafer are placed into the ultrasonic cleaning tank, the collection basket and the photovoltaic silicon wafer are in a static state in the ultrasonic cleaning tank, which will form cleaning blind spots in some areas. This results in limited cavitation effect on certain parts of the silicon wafer surface, and the removal of impurities takes a long time and has low impurity removal efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a front main grid pretreatment cleaning machine, which has the advantages of high cleaning efficiency and self-clamping and fixing.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a front main grid pretreatment cleaning machine, including a cleaning tank, a placement seat symmetrically arranged inside the cleaning tank, a connecting shaft fixedly connected to the bottom of the placement seat and rotatably connected to the cleaning tank through a waterproof bearing, a driving mechanism provided at the bottom of the cleaning tank, a pressure groove opened at the top of the placement seat, a pressure block slidably connected inside the pressure groove, a plurality of connecting grooves communicating with the pressure groove at the top of the placement seat, the number of connecting grooves being four, a connecting block slidably engaged inside the connecting groove, and a force-applying block slidably connected to one end of the pressure block fixedly connected to the bottom of the pressure block.

[0005] The above technical solution utilizes a placement seat within the cleaning tank. A drive mechanism rotates the connecting shaft, which in turn rotates the placement seat, causing the storage basket placed on the placement seat to rotate. This allows the photovoltaic silicon wafers inside the basket to rotate while undergoing ultrasonic cleaning in the cleaning fluid, reducing blind spots and improving cleaning efficiency. Furthermore, pressure blocks inside the pressure groove lower the pressure when the storage basket is placed on the placement seat. Under the action of these pressure blocks, four connecting blocks slide within the connecting groove, shortening the distance between them and clamping and limiting the storage basket at the top of the placement seat. This ensures stability when the placement seat rotates the storage basket within the cleaning tank.

[0006] The present invention is further configured such that the driving mechanism includes a driving motor, one end of the connecting shaft extends through to the bottom of the cleaning tank and is fixedly sleeved with a rotating wheel, a transmission belt is connected between the two rotating wheels, and the output end of the driving motor is fixedly connected to the connecting shaft.

[0007] The above technical solution is adopted: when the drive motor starts, it can drive the rotating wheel connected to the drive motor to rotate. When the rotating wheel rotates, it can drive another rotating wheel to rotate under the action of the transmission belt, so that the two placement seats inside the cleaning tank rotate simultaneously.

[0008] The present invention is further configured such that an ultrasonic transducer is installed at the bottom of the cleaning tank, and an ultrasonic generator is fixedly connected to the bottom of the ultrasonic transducer.

[0009] Using the above technical solution: the ultrasonic generator can convert electrical energy into high-frequency mechanical waves, the ultrasonic transducer can convert the mechanical waves into mechanical vibrations, and then radiate them into the cleaning liquid inside the cleaning tank through the tank wall.

[0010] The present invention is further configured such that an annular guide block is bolted to the bottom of the placement seat, and an annular guide groove is provided inside the cleaning tank to slide in connection with the annular guide block.

[0011] The above technical solution is adopted to limit the rotation of the placement seat.

[0012] The present invention is further configured such that a groove is provided inside the connecting groove, a top block is slidably connected inside the groove, and a spring is engaged between the top block and the groove.

[0013] Using the above technical solution: when no storage basket is placed on the placement seat, the top block and spring can apply a pushing force to the connecting block, and under the action of the connecting block, the pressure block is dislodged from the pressure groove.

[0014] The present invention is further configured such that a fixing seat is snapped onto the surface of the drive motor, and the fixing seat is fixedly connected to the bottom of the cleaning tank.

[0015] The above technical solution is adopted to limit and fix the drive motor.

[0016] The present invention is further configured such that a plurality of support legs are fixedly connected to the bottom of the cleaning tank, a drain pipe is connected to the bottom of the cleaning tank, and a valve is installed on the surface of the drain pipe.

[0017] The above technical solution provides support and fixation for the cleaning tank and facilitates the removal of cleaning fluid from inside the tank.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model has a placement seat inside the cleaning tank. Under the action of the drive mechanism, the connecting shaft can be driven to rotate, thereby driving the placement seat to rotate, which in turn drives the storage basket placed on the placement seat to rotate. This allows the photovoltaic silicon wafers inside the storage basket to rotate while being ultrasonically cleaned in the cleaning liquid, reducing blind spots in the cleaning process and improving cleaning efficiency.

[0020] 2. This utility model uses a pressure block inside the pressure groove. When the storage basket is placed on the placement seat, the pressure block is subjected to pressure and drops. Under the action of the force block, the four connecting blocks slide inside the connecting groove, thereby shortening the distance between the four connecting blocks and clamping and limiting the storage basket on the top of the placement seat. This makes it easier for the placement seat to keep the storage basket stable when it rotates inside the cleaning tank. Attached Figure Description

An ultrasonic transducer 10 is mounted at the bottom of the cleaning tank 1, and an ultrasonic generator 11 is fixedly connected to the bottom of the ultrasonic transducer 10. By setting the ultrasonic transducer 10 and the ultrasonic generator 11, the ultrasonic generator 11 can convert electrical energy into high-frequency mechanical waves, and the ultrasonic transducer 10 can convert these mechanical waves into mechanical vibrations, which are radiated through the tank wall into the cleaning liquid inside the tank. A placement seat 2 is symmetrically arranged inside the cleaning tank 1, and an annular guide block 12 is bolted to the bottom of the placement seat 2. An annular guide groove 13 is slidably connected to the annular guide block 12 inside the cleaning tank 1. The annular guide block 12 and the annular guide groove 13 limit the rotation of the placement seat 2. A connecting shaft 3 is fixedly connected to the bottom of the placement seat 2 and rotatably connected to the cleaning tank 1 via a waterproof bearing. A drive mechanism 4 is provided at the bottom of the cleaning tank 1, and the drive mechanism 4 includes a drive motor 41. One end of the connecting shaft 3 extends through to the bottom of the cleaning tank 1. The unit is fixedly fitted with a rotating wheel 42, and a transmission belt 43 is connected between the two rotating wheels 42. The output end of the drive motor 41 is fixedly connected to the connecting shaft 3. By setting up the drive motor 41, the rotating wheel 42 and the transmission belt 43, when the drive motor 41 is started, it can drive the rotating wheel 42 connected to the drive motor 41 to rotate. When the rotating wheel 42 rotates, it can drive the other rotating wheel 42 to rotate under the action of the transmission belt 43, so that the two placement seats 2 inside the cleaning tank 1 rotate simultaneously. The surface of the drive motor 41 is clamped with a fixed seat 17, and the fixed seat 17 is fixedly connected to the bottom of the cleaning tank 1. By setting up the fixed seat 17, the drive motor 41 is limited and fixed. Multiple support legs 18 are fixedly connected to the bottom of the cleaning tank 1. The bottom of the cleaning tank 1 is connected to a drain pipe 19, and a valve is installed on the surface of the drain pipe 19. By setting up the support legs 18 and the drain pipe 19, the cleaning tank 1 is supported and fixed and the cleaning liquid inside the cleaning tank 1 is conveniently discharged.

[0029] Brief description of the usage process: Using an external clamp, the storage basket containing the photovoltaic silicon wafers is placed on the placement seat 2 inside the cleaning tank 1. Under the action of the drive mechanism 4, the connecting shaft 3 can be rotated, thereby driving the placement seat 2 to rotate, which in turn drives the storage basket placed on the placement seat 2 to rotate. This allows the photovoltaic silicon wafers inside the storage basket to rotate while being ultrasonically cleaned in the cleaning fluid, reducing blind spots in the cleaning process and improving cleaning efficiency.

[0030] Example 2:

[0031] refer to Figure 1 , Figure 2 and Figure 3A front main grid pretreatment cleaning machine has a pressure groove 5 on the top of the placement seat 2. A pressure block 6 is slidably connected inside the pressure groove 5. The top of the placement seat 2 has multiple connecting grooves 7 communicating with the pressure groove 5. There are four connecting grooves 7. A connecting block 8 is slidably engaged inside the connecting groove 7. A groove 14 is opened inside the connecting groove 7. A top block 15 is slidably connected inside the groove 14. A spring 16 is engaged between the top block 15 and the groove 14. By setting the top block 15, the groove 14 and the spring 16, when no storage basket is placed on the placement seat 2, the top block 15 and the spring 16 can apply a pushing force to the connecting block 8. Under the action of the connecting block 8, the pressure block 6 is dislodged from the pressure groove 5. A force-applying block 9 is fixedly connected to the bottom of the pressure block 6 and slidably connected to one end of the connecting block 8.

[0032] Brief description of the usage process: When the storage basket is placed on the placement seat 2, the pressure block 6 is lowered by the pressure. Under the action of the force block 9, the four connecting blocks 8 are driven to slide inside the connecting groove 7, thereby shortening the distance between the four connecting blocks 8 and clamping and limiting the storage basket on the top of the placement seat 2, so that the placement seat 2 can keep the storage basket stable when rotating inside the cleaning tank 1.
