This not only compromises cleaning effectiveness but can also lead to secondary dust accumulation interfering with precision electrical performance testing, becoming a bottleneck restricting yield improvement and production continuity. There is an urgent need for a new testing device that can be seamlessly integrated into the production line and possesses highly efficient closed-loop cleaning capabilities. Utility Model Content

Figure 3 for Figure 1 A cross-sectional structural diagram of the collection box shown; Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. A novel back-junction battery manufacturing apparatus includes: a moving device 1, a support frame 2, and a limiting device 3;

The limiting device 3 includes two first telescopic members 31 and two limiting plates 32. The two first telescopic members 31 are fixedly installed on both sides of the support frame 2, and one side of each of the two limiting plates 32 is fixedly installed on the output end of the two first telescopic members 31.

[0028] Both of the limiting plates 32 are equipped with adjustment devices 4 inside, and probes 14 are fixedly installed inside both of the adjustment devices 4.

[0029] A cleaning device 5 is provided on the top of the support frame 2. The cleaning device 5 includes a collection box 51, a collection pipe 52, a filter screen 53, a fan 54, a conveying pipe 55, and an air outlet pipe 56. The collection box 51 is fixedly installed on the top of the support frame 2. One end of the collection pipe 52 is fixedly installed on one end of the collection box 51. The filter screen 53 is fixedly installed inside the collection box 51. The fan 54 is fixedly installed inside the collection box 51. One end of the conveying pipe 55 is fixedly installed on one end of the collection box 51. The top of the air outlet pipe 56 is fixedly installed on one end of the conveying pipe 55.

After moving to the two limit plates 32, the conveyor belt automatically closes after a certain period of time and then starts moving again to convey the next product to one side.

[0031] The first telescopic component 31 consists of a cylinder, a hydraulic rod, and an electric push rod.

[0032] The adjusting device 4 includes a sliding groove 41, a sliding block 42, and a fixing member 43. The sliding groove 41 is formed inside the limiting plate 32, the sliding block 42 is slidably connected to the inside of the sliding groove 41, and the fixing member 43 is disposed inside the block 42.

[0033] The probe 14 is fixedly installed inside the sliding block 42. By loosening the fixing piece 43, the sliding block 42 is moved to one side, thereby moving to one side inside the sliding groove 41 to adjust the position of the probe 14.

[0034] The fixing component 43 is a bolt, and the sliding block 42 has a threaded hole that matches the bolt inside. When the bolt is rotated to one side, the bolt moves inside the threaded hole. When one end of the bolt contacts the surface of the sliding groove 41, it limits the sliding block 42. When one end of the bolt separates from the inner wall of the sliding groove 41, it allows the sliding block 42 to move.

[0035] A suction head is fixedly installed at one end of the collection tube 52 for sucking up the blown dust.

[0036] The air outlet pipe 56 is fixedly installed on one side of the inner wall of the support frame 2. Multiple nozzles are fixedly installed on the surface of the air outlet pipe 56. The air blown by the fan 54 is transported into the air outlet pipe 56 through the conveying pipe 55 and sprayed out from the multiple nozzles to clean the surface of the product.

[0037] In use, after the product enters the conveying device 1, the conveying device 1 starts and moves the product to one side a certain distance. After the product moves between the two limiting plates 32, the two first telescopic members 31 are activated to move the two limiting plates 32 to one side, clamping the product while driving multiple probes 14 to contact the product for detection.

[0038] After the test is completed, the two first telescopic components 31 retract, causing the two limit plates 32 to reset.

[0039] At the same time, the blower 54 is started to blow air into the conveying pipe 55, so that the air outlet pipe 56 blows out more air to clean the surface of the product. Meanwhile, the collection pipe 52 generates suction to absorb the blown dust. The dust enters the inside of the collection box 51, and after being filtered by the filter screen 53, the air enters the inside of the conveying pipe 55 and is blown out through the air outlet pipe 56.

[0040] The support frame 2 is equipped with a lifting device 6 inside. The lifting device 6 includes a moving groove 61, a moving frame 62, and a lifting component 63.

The lifting component 63 is fixedly installed on the top of the support frame 2.

[0041] The lifting component 63 is fixedly installed on the top of the support frame 2 and is used to push the movable frame 62 to move.

[0042] The lifting component 63 consists of a cylinder, a hydraulic rod, and an electric push rod.

[0043] The movable frame 62 is equipped with a cleaning device 7, which includes a cleaning roller 72 and a rotating motor 71. The cleaning roller 72 is rotatably connected to the inside of the movable frame 62, and the rotating motor 71 is fixedly installed at one end of the movable frame 62.

[0044] The rotating motor 71 is a servo motor, and its output end is connected to one end of the cleaning roller 72 via a coupling to rotate.

[0045] In use, the cleaning roller 72 is rotated to one side by starting the rotating motor 71 to clean the surface of the product.

[0046] By activating the lifting component 63, the moving frame 62 moves inside the moving groove 61, thereby adjusting the height of the cleaning roller 72.

[0047] The working principle of the novel back-junction battery manufacturing device provided by this utility model is as follows:

[0048] When using it, first select a suitable high-purity P-type or N-type single crystal silicon wafer, then clean the silicon wafer and etch it.

[0049] On the back side of the P-type silicon wafer, the N-type silicon wafer is placed in a high-temperature diffusion device through a photoresist mask to perform back boron diffusion, forming a P-type doped polysilicon layer, and a back BSG layer is deposited on the surface of the P-type doped polysilicon layer, followed by laser etching or plasma etching.

[0050] Front passivation to reduce reflection and back passivation, followed by laser grooving;

[0051] Hard brushes are applied to interdigitated electrodes via screen printing and electroplating, and the electrodes are then annealed at high temperature after printing.

[0052] After the battery is conveyed to one side between the two limiting devices 3 by the conveying device 1, the conveying device 1 stops. While the limiting device 3 limits the battery, the probe 14 automatically detects the battery. At the same time, one end of the cleaning device 5 blows air to clean the surface of the battery, while the other end sucks up and collects the dust blown up.
