[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1 and Figure 2 The present invention provides an ion air knife blowing mechanism for manufacturing solar cells, comprising: a base plate 1 and a mounting structure 3.

The mounting structure 3 is provided on the inner wall of the mounting plate 5. An auxiliary structure 4 is provided on the upper surface of the base plate 1.

[0032] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The installation structure 3 includes two positioning grooves 301, four fixing rods 304, and two telescopic rods 310. The inner walls of the two positioning grooves 301 are formed on the mounting plate 5. The four fixing rods 304 are fixedly connected to the mounting plate 5, and the two telescopic rods 310 are fixedly connected to the mounting plate 5. Connecting plates 302 are slidably connected to the inner walls of the positioning grooves 301. The two connecting plates 302 are fixedly connected to the ion air bar 6. The inner walls of the connecting plates 302 are provided with slots 303. The four fixing rods 304 are arranged in pairs, and a movable plate 306 is slidably connected to the arc surface of one pair of fixing rods 304. A locking block 313 is fixedly connected to the inner wall of the movable plate 306 near the slot 303. A spring 305 is sleeved on the arc surface of the fixed rod 304. The two ends of the spring 305 are fixedly connected to the movable plate 306 and the fixed rod 304 respectively. The locking block 313 is slidably connected to the slot 303. An adjusting block 308 is fixedly connected to the output end of the telescopic rod 310. A compression spring 311 is sleeved on the arc surface of the telescopic rod 310. The two ends of the compression spring 311 are fixedly connected to the adjusting block 308 and the mounting plate 5 respectively. A pressing plate 307 is fixedly connected to the side of the adjusting block 308 near the movable plate 306. When personnel need to fix the ion air bar 6 onto the mounting plate 5, they can move the mounting plate 5 to slide the connecting plate 302 into the inner wall of the positioning groove 301 and the locking block 313 into the inner wall of the locking groove 303, thus facilitating the installation of the ion air bar 6 and improving installation efficiency.

Stainless steel blocks have high strength and good wear resistance, which can prevent deformation of the 313 block during short-term use;

[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 4 includes two fixed plates 401, which are fixedly connected to the base plate 1. A top plate 405 is fixedly connected to the upper surface of the two fixed plates 401. A protective cover 413 is fixedly connected to one side of the top plate 405. A motor 411 is fixedly connected to the inner wall of the protective cover 413. A limiting groove 406 is formed in the inner wall of the top plate 405. A moving block 409 is slidably connected to the inner wall of the limiting groove 406. A lead screw 408 is rotatably connected to the inner wall of the limiting groove 406. The lead screw 408 is threadedly connected to the moving block 409. The lead screw 408 is rotatably connected to the top plate 405. A cleaning brush 410 is fixedly connected to the lower surface of the moving block 409. A conductive plate 402 is fixedly connected to the side of one of the fixed plates 401 near the cleaning brush 410. Several conductive posts 403 are fixedly electrically connected to the side of the conductive plate 402 near the cleaning brush 410. A connecting wire 404 is fixedly electrically connected to the lower surface of the conductive plate 402. Before the solar cell body 7 passes through the ionizer 6, the moving cleaning brush 410 can perform preliminary cleaning of dust and particles on the surface of the solar cell body 7, thereby improving the cleanliness of the surface of the solar cell body 7. Two limiting rods 407 are fixedly connected to the inner wall of the limiting groove 406, and the limiting rods 407 are slidably connected to the moving block 409. The limiting rods 407 can limit the moving block 409, preventing misalignment during sliding on the inner wall of the limiting groove 406. Several heat dissipation holes 412 are evenly distributed on the arc surface of the protective cover 413. The heat dissipation holes 412 can assist the motor 411 in heat dissipation, thereby extending the service life of the motor 411.

[0034] The working principle of the ion air knife cleaning mechanism for solar cell manufacturing provided by this utility model is as follows: Before the screen printing process of the solar cell body 7, the static electricity and particulate dust adhering to the surface of the solar cell body 7 can be removed by the ion air bar 6 to reduce the probability of screen printing failure. Then, when the personnel need to fix the ion air bar 6 on the mounting plate 5, the personnel can first move the ion air bar 6. The ion air bar 6 drives the two connecting plates 302 to move closer to the positioning groove 301. The connecting plates 302 drive the guide plate 31. 2. Move towards the positioning groove 301. The guide plate 312 guides the connecting plate 302, facilitating its sliding into the inner wall of the positioning groove 301. Continue until both the guide plate 312 and the connecting plate 302 are inside the positioning groove 301. During this sliding motion, the guide plate 312 abuts against the locking block 313, causing it to move away from the other two blocks. The locking block 313 then moves the moving plate 306 away from the mounting plate 5. Plate 306 drives two springs 305 to rewind until the locking block 313 aligns with the locking slot 303. At this point, the springs 305 rebound, causing the locking block 313 to move closer to the locking slot 303 until it slides into the inner wall of the slot 303. Then, when personnel need to disassemble and repair the ion air bar 6, they can move the anti-slip pad 309 closer to the mounting plate 5. The anti-slip pad 309 increases the friction between the personnel's hands and the adjusting block 308, preventing slippage during operation. During the movement, slippage occurs, and then the adjusting block 308 drives the output end of the pressing plate 307 and the telescopic rod 310 to move closer to the moving plate 306. The adjusting block 308 also drives the compression spring 311 to retract until the inclined surface of the pressing plate 307 abuts against the moving plate 306. Then the pressing plate 307 drives the moving plate 306 to move away from the mounting plate 5 until the locking block 313 slides into the inner wall of the slot 303. The stainless steel locking block 313 has high strength and good wear resistance, which can prevent the locking block 313 from deforming during short-term use.

[0035] Additionally, as the automated track 2 moves the solar cell body 7 closer to the cleaning brush 410, the motor 411 can be activated. The output of the motor 411 drives the lead screw 408 to rotate, and the lead screw 408 drives the moving block 409 to move away from the motor 411. The moving block 409 slides on the arc surface of the two limiting rods 407. The limiting rods 407 can limit the moving block 409, preventing it from becoming misaligned during sliding on the inner wall of the limiting groove 406. 9 drives the cleaning brush 410 to move away from the motor 411, and then the cleaning brush 410 cleans the surface of the solar cell body 7 until the conductive post 403 is inserted into the cleaning brush 410. Then the static electricity inside the cleaning brush 410 will be conducted to the ground through several conductive posts 403, conductive plates 402 and connecting wires 404, thereby eliminating the static electricity inside the cleaning brush 410 and facilitating subsequent cleaning. The heat dissipation holes 412 opened on the inner wall of the protective cover 413 can assist the motor 411 in heat dissipation and improve the service life of the motor 411.
