Description

Technical Field

[0001] This invention relates to the field of suction cup handling technology, and in particular to a photovoltaic silicon wafer handling structure and method with a plastic snap-on ceramic suction cup. Background Technology

[0002] In the production process of photovoltaic cells, photovoltaic silicon wafers play a crucial role. Currently, suction cups are typically used to adsorb silicon wafers through negative pressure, achieving stable handling and positioning of the silicon wafers, ensuring the stability and accuracy of the silicon wafers during the production process, and significantly improving production efficiency.

[0003] Currently, ceramic suction cups have poor fixing effect during use, which easily leads to unstable adsorption. This causes photovoltaic silicon wafers to slip or be damaged during transportation, resulting in direct economic losses. It not only increases production costs but may also affect the progress of the entire production line. Furthermore, during installation, ceramic suction cups may need to be frequently adjusted in position, which greatly increases transportation and processing time and reduces production efficiency. In view of this, the present invention is proposed. Summary of the Invention

[0027] 1. This photovoltaic silicon wafer handling structure with plastic snap-on ceramic suction cups inserts the suction cup assembly into the mounting slot and fixes it with a U-shaped clamp. Then, clips are installed on both sides of the mounting block to further secure the suction cup assembly, preventing the photovoltaic silicon wafers from slipping or being damaged during handling, thus improving production efficiency. The suction nozzle is made of wear-resistant plastic, which prevents microcracks from forming when adsorbing photovoltaic silicon wafers.

[0028] 2. This photovoltaic silicon wafer handling structure with a plastic snap-on ceramic suction cup allows the suction cup assembly to be inserted into the mounting slot. The bottom of the suction cup assembly then presses against the clamping block. Under the pressure of the second elastic element, the clamping block tightly clamps the bottom of the suction cup assembly, making the installation more stable and preventing the photovoltaic silicon wafer from slipping or being damaged during handling.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] Example 1:

[0043] Reference Figures 1-10 A photovoltaic silicon wafer handling structure with a plastic snap-on ceramic suction cup includes a lower base 1 and an upper base 2, and a partition 102 fixedly connected between the lower base 1 and the upper base 2; a mounting block 4 slidably disposed on the partition 102, the mounting block 4 having multiple mounting grooves 401 connected at their bottoms; a suction cup assembly 402 inserted into the mounting groove 401, the suction cup assembly 402 having a suction nozzle 403 for adsorbing photovoltaic silicon wafers, and an air passage 404 connected to the suction nozzle 403; a locking block 410 for fixing the suction cup assembly 402, installed on both sides of the mounting block 4; and a U-shaped clamp 405 slidably disposed in the mounting groove 401, the bottom of the suction cup assembly 402 inserted into the U-shaped clamp 405.

[0044] In this embodiment, before use, the suction cup assembly 402 is first installed on the mounting block 4. Specifically, the suction cup assembly 402 is inserted into the mounting groove 401, and then the bottom of the suction cup assembly 402 is inserted into the U-shaped clamp 405, thereby fixing the suction cup assembly 402 through the U-shaped clamp 405. At the same time, when the suction cup assembly 402 is inserted, it will press the U-shaped clamp 405 to move downward. Then, the locking blocks 410 are installed on both sides of the mounting block 4 to further fix the suction cup assembly 402, thereby making its connection more stable, preventing the photovoltaic silicon wafer from slipping or being damaged during transportation, avoiding waste of production costs, and ensuring the progress of the entire production line. Moreover, during the installation process, the ceramic suction cup does not need to be frequently adjusted to fix its position, reducing transportation and processing time and improving production efficiency. When in use, the suction cup assembly 402 is used through the suction nozzle 403. It can adsorb photovoltaic silicon wafers, and each mounting block 4 is equipped with multiple suction cup assemblies 402, which can simultaneously handle multiple photovoltaic silicon wafers. It should be noted that during use, multiple photovoltaic silicon wafers can be simultaneously mounted and adsorbed onto the suction cup assembly 402 through the preceding work, improving the efficiency of use. The suction nozzle 403 is made of wear-resistant plastic, which can prevent microcracks from forming when adsorbing photovoltaic silicon wafers. The suction cup assembly 402 is made of ceramic material, which can improve the overall hardness and avoid leaving suction cup marks on the silicon wafer. It can achieve a good adsorption effect with no iron or magnetism and a flat surface, thus distributing the adsorption force more evenly. This ensures that the photovoltaic silicon wafer or battery and other objects are subjected to uniform force during adsorption, and are not easy to slip or shift. The characteristics of no iron and no magnetism make the ceramic suction cup usable in various environments, unaffected by magnetic field interference, improving its applicability and reliability.

[0045] Reference Figures 7-10 A first elastic element 406 is provided between the U-shaped clamp 405 and the bottom inner wall of the mounting groove 401. A groove 407 is provided on both sides of the suction cup assembly 402 on the U-shaped clamp 405. A clamping block 409 is slidably connected in both grooves 407. A second elastic element 408 is provided between the clamping block 409 and the inner wall of the groove 407. The suction nozzle 403 is made of wear-resistant nylon, PEEK, or silicone.

[0046] The mounting slot 401 is provided with a sliding groove 414, and a baffle 413 is slidably connected in the sliding groove 414. A support rod 412 is fixedly connected between the baffle 413 and the U-shaped clamp 405.

[0047] Specifically, in use, the suction cup assembly 402 is inserted into the mounting slot 401, and then the bottom of the suction cup assembly 402 is inserted into the U-shaped clamping plate 405, thereby squeezing the clamping block 409 and causing the clamping block 409 to move into the grooves 407 on both sides. At the same time, the second elastic element 408 in the groove 407 is compressed. Under the pressure of the second elastic element 408, the clamping block 409 tightly clamps the bottom of the suction cup assembly 402, making its installation more stable. The top of the clamping block 409 is provided with a slope, so when the suction cup assembly 402 is pressed down, the two clamping blocks 409 can be better separated, allowing it to better clamp the suction cup assembly 402 and fix the suction cup assembly 402. When the suction cup assembly 402 is pressed down, the U-shaped clamping plate 405 is pressed down simultaneously. Simultaneously, the first elastic element 406 is compressed, causing it to be compressed. This compression, in turn, causes the baffle 413 to move via the support rod 412. Initially, the baffle 413 blocks the locking block 410, preventing its installation. However, as the U-shaped clamp 405 moves downward, the baffle 413 moves downward, allowing the locking block 410 to be installed more easily, thus making the suction cup assembly 402 more stable. The sliding groove 414 facilitates the movement of the support rod 412. The locking blocks 410 are then installed on both sides of the mounting block 4 to further secure the suction cup assembly 402, enabling it to operate. It should be noted that both the first elastic element 406 and the second elastic element 408 can be springs or sheet springs, as long as they can achieve a reciprocating spring effect.

[0048] Secondly, the inverted suction nozzle 403 is designed using wear-resistant plastics such as wear-resistant nylon, PEEK, and silicone, which is combined with the ceramic suction cup assembly 402 to form a special composite suction cup. This retains the characteristics of ceramic suction cups, such as being non-ferrous, non-magnetic, and having good flatness, while also having the characteristics of plastic suction cups. This prevents microcracks and suction cup marks from forming on BC batteries and TOPcon batteries, thus improving the performance.

[0049] Example 2:

[0050] Reference Figures 1-10 A photovoltaic silicon wafer handling structure with a plastic snap-on ceramic suction cup includes a lower base 1 and an upper base 2, and a partition 102 fixedly connected between the lower base 1 and the upper base 2; a mounting block 4 slidably disposed on the partition 102, the mounting block 4 having multiple mounting grooves 401 connected at their bottoms; a suction cup assembly 402 inserted into the mounting groove 401, the suction cup assembly 402 having a suction nozzle 403 for adsorbing photovoltaic silicon wafers, and an air passage 404 connected to the suction nozzle 403; a locking block 410 for fixing the suction cup assembly 402, installed on both sides of the mounting block 4; and a U-shaped clamp 405 slidably disposed in the mounting groove 401, the bottom of the suction cup assembly 402 inserted into the U-shaped clamp 405.

[0051] Reference Figures 1-7 There are multiple mounting blocks 4, and multiple suction cup assemblies 402 are inserted into each mounting block 4. Two sliders 305 are provided on the outer wall of each mounting block 4. Limiting grooves 103 are provided on the lower base 1, the partition 102 and the upper base 2. The two sliders 305 are slidably connected in the limiting grooves 103. A fixing rod 101 is also fixedly connected between the lower base 1 and the upper base 2.

[0052] Reference Figures 1-6 A threaded rod 303 and a limiting rod 304 are respectively provided in the limiting groove 103. The threaded rod 303 is rotatably connected in the limiting groove 103. One of the sliders 305 located on the outer wall of the mounting block 4 is threadedly connected to the threaded rod 303, and the other slider 305 located on the outer wall of the mounting block 4 is slidably mounted on the limiting rod 304.

[0053] Reference Figures 1-6 The lower base 1 is provided with a recessed hole that communicates with the limiting groove 103. A first gear 301 is rotatably connected in the recessed hole. A second gear 302 is fixedly connected to the outer wall of the threaded rod 303. The first gear 301 and the second gear 302 mesh with each other. A first driving part 3 is fixedly connected to the outer wall of the lower base 1. The first gear 301 is located at the output end of the first driving part 3. When the first driving part 3 works, it can drive the first gear 301 located in the recessed hole to rotate.

[0054] In this embodiment, the first drive unit 3 is activated, causing the first gear 301 at the output end to rotate, which in turn drives the second gear 302 meshing with it to rotate, and then drives the threaded rod 303 connected to the second gear 302 to rotate. This causes the threaded rod 303 to be threadedly connected to one of the sliders 305 on the mounting block 4, thereby driving the mounting block 4 to move, realizing the movement of the suction cup assembly 402 and the photovoltaic silicon wafer. At the same time, the other slider 305 on the mounting block 4 will slide on the limiting rod 304, which can improve the stability of the movement and make the movement of the mounting block 4 more stable, facilitating the transportation of the photovoltaic silicon wafer. The first drive unit 3 is specifically a motor.

[0055] Reference Figures 1-7 and Figure 10 A pump body 201 is fixedly connected to the upper base 2. A connecting pipe 411 is provided on the pump body 201. The end of the connecting pipe 411 away from the pump body 201 is connected to the mounting groove 401 on the mounting block 4. An end plate 202 and a limiting plate 203 are also fixedly connected to the upper base 2. A stop bar 204 is provided on both sides of the limiting plate 203. The suction cup assembly 402 is located between the two sets of stop bars 204 on the limiting plate 203.

[0056] In this embodiment, the pump body 201 enables air extraction, drawing gas from the mounting groove 401 via the connecting pipe 411. This gas is then drawn into the suction nozzle 403 via the air passage 404, allowing the nozzle 403 to better grip the suction cup. The pump body 201 delivers air, causing the photovoltaic silicon wafer to detach from the nozzle 403. The limiting plate 203 and the stop bar 204 are designed to limit the movement of the photovoltaic silicon wafer, facilitating its handling.

The lead screw 504 is located at the output end of the second drive unit 503. The slide block 505 is threadedly connected to the lead screw 504. A limit frame 506 is fixedly connected to the bottom of the slide block 505. A telescopic motor 507 is located inside the limit frame 506. A rubber pad is provided on the outer wall of the push plate 509.

[0061] In this embodiment, the specific working steps of the flattening component are as follows: First, the second drive unit 503 is started, which drives the lead screw 504 at its output end to rotate, thereby driving the slide block 505 threadedly connected to the lead screw 504 to move, thereby causing the slide block 505 to drive the limiting frame 506 to move, thereby causing the telescopic motor 507 inside the limiting frame 506 to move, and the telescopic motor 507 is started, which pushes the push plate 509 to move.

[0066] Activating the first drive unit 3 can drive the threaded rod 303 to rotate, thereby driving the mounting block 4 to move, which in turn causes the suction cup assembly 402 to drive the photovoltaic silicon wafer to move.

[0067] The flattening components can make the photovoltaic silicon wafers more neatly arranged.
