[0045] Usually, photovoltaic cells need to be cut with the help of a dicing machine. The cell material is cut by laser, and the larger cell is cut into a size that meets the actual needs according to production requirements. In order to ensure the accuracy of the dicing position, a corresponding guiding structure is also required to adjust the position of the cell material. Traditional guiding structures are mostly set as fixed ridges on the dicing station. The cell material is limited and guided at the fixed ridges through a feeding structure combined with manual alignment. This guiding method consumes dicing time and reduces work efficiency. In the process of placing the cell, it is difficult to ensure the high-precision accuracy of the cell material position, which easily affects the production efficiency and dicing quality.

[0046] In order to solve the above problems, the utility model proposes a photovoltaic cell slicer. Figures 1 to 4 The present invention is a schematic structural diagram of an embodiment of a photovoltaic cell dicing machine provided by the present invention.

[0047] Please refer to Figures 1 to 4The utility model proposes a photovoltaic cell dicing machine 2000, which includes a feeding module 6, a dicing module 4 and a guiding module 2 arranged on a workbench 1, wherein the feeding module 6 is used to sort and stack the cell materials to be processed, and the dicing module 4 is used to cut the cell materials by laser cutting. Specifically, when the entire device is working, the cell materials are transferred from the feeding module 6 and the guiding module 2 to the dicing module 4 in sequence by the material transfer mechanism 3. Before the cell materials enter the dicing module 4 for laser cutting, the horizontal position of the cell materials needs to be adjusted to ensure the accuracy of the laser cutting position as much as possible. Therefore, a corresponding guiding structure is set to adjust the horizontal position of the cell materials. Traditional guiding structures are mostly static settings. For example, a corresponding baffle structure is installed on the dicing module 4 along the conveying direction of the cell materials. When the cell materials are conveyed to the dicing module Module 4, the battery cell material is limited by the baffle structure to achieve static adjustment of the horizontal position of the battery cell material. However, this static adjustment method makes it difficult to adjust the X and Y directions of the battery cell material in the horizontal direction at the same time, which will affect the cutting position of the dicing module 4. Manual intervention to adjust the position of the battery cell material will affect the production efficiency and it is difficult to ensure the stability of production. In this embodiment, in order to avoid the above problems, the guiding module 2 is arranged between the feeding module 6 and the dicing module 4, and the horizontal position of the battery cell material is dynamically adjusted before the battery cell material enters the dicing module 4. The battery cell material on the guiding module 2 is guided while the material transfer mechanism 3 picks up the material on the feeding module 6, so that the material picking time and the material guiding time overlap, which directly reduces the traditional production time of guiding the battery cell material on the dicing module 4, and can effectively improve the efficiency of actual production.

[0048] Specifically, the material moving mechanism 3 places the battery cell material on the receiving platform 21, and the first cylinder 23 in the guiding module 2 drives the mounting plate 24 at its end to slide on the workbench 1. The two baffle members 25 on the mounting plate 24, which are 90 degrees to each other, contact the two adjacent right-angled sides of the battery cell material and gently push the battery cell material to move on the receiving platform 21, thereby adjusting the X and Y positions of the battery cell material in the horizontal direction at the same time. This adjustment method can dynamically limit the two right-angled sides of the battery cell material at the same time. Compared with the traditional static adjustment method, it can adapt to the production operations of battery cell materials of different specifications, and can make targeted adjustments to the movement stroke of the first cylinder 23 according to the different specifications of the battery cell materials, so as to meet the effect of pushing and adjusting battery cell materials of different specifications to the appropriate production position, and dynamically adjusting by means of a 90-degree angle can effectively ensure the accuracy of the battery cell material after position adjustment.

[0049] Among them, in order to further improve the applicability of the entire guiding module 2, inward grooves are provided on the two adjacent end portions in the horizontal direction of the material receiving platform 21 to avoid the movement position of the two baffle members. On the one hand, the weight of the material receiving platform 21 is reduced, and on the other hand, the movement stroke of the two baffle members is increased. When the production specifications of the battery cell material are small, its position can also be adjusted through the two baffle members.

[0050] In order to make the material transfer mechanism 3 have higher working efficiency, in this embodiment, the suction member in the material transfer mechanism 3 includes a first suction part 32 and a second suction part 33, the first suction part 32 is used to move the battery cell material from the loading module 6 to the receiving platform 21, and the second suction part 33 is used to transfer the battery cell material on the receiving platform 21 to the dicing module 4, wherein the first suction part 32 and the second suction part 33 are arranged on the same movable plate 34, and the first driving member 31 drives the first suction part 32 and the second suction part 33 to operate simultaneously during operation, which can effectively improve the efficiency of material transfer.

[0051] In addition, the two suction parts of the material transfer mechanism 3 work simultaneously, and while the material transfer mechanism 3 returns to its position, the battery cell material located at the guiding module 2 is guided. One suction part loads the material and the other suction part takes the cell at the same time, so that the loading and taking time of the two suction parts overlap. When the first suction part 32 takes the material by resetting the movement, the first cylinder 23 performs a synchronous guiding operation. The working hours of the guiding operation overlap with the working hours of the material taking and returning movement, which can further shorten the production cycle of the entire device and avoid the problem that traditional equipment needs to add more motion axes to achieve the beat, which makes the overall equipment position larger.

[0052] When the suction member is working, the second cylinder 331 drives the mounting portion 332 to rise and fall in the vertical direction according to the actual material taking and releasing position, and the negative pressure element (not shown in the figure) provides negative pressure suction at the multiple suction nozzles 333 on the mounting portion 332, which can absorb and release the solar panel material. It can be imagined that in the structure of the first suction portion 32 and the second suction portion 33 mentioned above contained in the suction member, the structure of the mounting portion 332 can be set to a disc structure, a frame structure, or one of the above structures respectively, which can be selected according to the actual production situation. The negative pressure element can be arranged on the workbench 1 or outside the workbench 1.

[0053] In order to make the entire structure of the photovoltaic cell dicing machine 2000 more compact, in this embodiment, the movement direction of the supporting platform 43 in the dicing module 4 is set perpendicular to the direction of the movable plate 34. Specifically, the second driving member 41 drives the supporting platform 43 to perform reciprocating feeding movement. After the second suction part 33 delivers the cell material on the receiving platform 21 to the supporting platform 43, the laser slicing module 42 on the workbench 1 cuts the cell material on the supporting platform 43 by laser. In this embodiment, in the process of the supporting platform 43 driving the cell material to move, the laser slicing module 42 completes the cutting operation of the cell material. It can be imagined that the laser slicing module 42 can include a cutting route adjustment module and a laser module. When in use, the laser output position of the laser module can be adjusted by the cutting route adjustment module, thereby controlling the cutting position of the laser module. In actual application, a variety of different cutting paths can be achieved.

[0054] In order to fully separate the battery cell materials after laser cutting, a folding plate module 5 is also provided on the workbench 1. Specifically, when the folding plate module 5 is working, the moving part first drives the folding plate member 53 to move, and the fixing module 54 on the folding plate member 53 takes the battery cell material on the supporting platform 43 and fixes the battery cell material on the downward end surface of the folding plate member 53. The folding plate member 53 breaks the battery cell material corresponding to the cutting position of the laser slicing module 42, so that the battery cell materials on both sides of the cutting part are fully separated. It can be imagined that the structure of the folding plate member 53 can be set to be similar to the structure of a door rotary leaf, and the movable part on one side of the door rotary leaf is fixed to the moving part, and the movable part on the other side is connected to the vertical driving part. The vertical driving part can drive the movable part connected to it on one side and the movable part on the other side fixedly installed to produce relative rotation. The fixing module 54 is installed at the downward end of the door rotary leaf. During the relative movement of the two movable parts, the battery cell material can be broken and separated corresponding to the cutting position.

[0055] When the third driving member 51 in the moving member is working, it drives the mounting plate 24 to make a reciprocating motion, so that the folding plate member 53 can realize a reciprocating material taking action.

[0056] In addition, it can be imagined that the first driving member 31, the second driving member 41 and the third driving member are all driving structures for vertical motion. There are many driving structures for vertical motion, such as linear motors, screw sliders, or electric / pneumatic push rods, etc., which can realize the relevant linear motion in this application and can be selected for use according to actual production conditions.

[0057] At the same time Figure 4 As shown, the overall machine structure in this scheme is U-shaped, and the driving directions of the first driving member 31, the second driving member 41 and the third driving member 51 are arranged perpendicular to each other, which is more conducive to saving the occupied space of the whole machine and making the overall structure of the photovoltaic cell dicing machine 2000 more compact. At the same time, the setting of the above structure avoids the problem that traditional dicing equipment needs to add more motion axes to achieve the beat, which makes the position of the whole equipment larger.

[0058] A receiving frame 11 is provided on the workbench 1 at a position below the folding plate 53 to collect the broken solar panel materials.

[0059] In order to improve the versatility of the loading module 6, a plurality of mounting grooves 621 are provided on the bottom plate portion 62 in the storage rack 61, and the downward ends of the plurality of limit rods 63 are fixedly installed in the limit grooves. During actual use, one end of the limit rod 63 can be adjusted to slide in the mounting groove 621 according to the actual size of the battery cell material, thereby changing the size of the enclosed area of ​​the plurality of limit rods 63 to adapt to the production of battery cell materials of different sizes.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
