Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic cell technology, and in particular relates to an automatic cutting device for photovoltaic cells. Background Technology

[0002] A photovoltaic cell is a semiconductor material component that can directly convert sunlight into electrical energy.

[0003] To improve the efficiency of solar modules and reduce losses, conductive adhesive strips are installed between the solar cells and the module to allow current to flow from the solar cells to the module. Therefore, it is necessary to cut a whole silicon wafer or multiple silicon wafers into smaller photovoltaic solar cells. Application number: CN202222504449.4 discloses a photovoltaic cell laser slicing device. This device uses an interceptor to intercept solar cells on an inclined bearing surface. After the laser cutting module cuts the solar cells, the interceptor releases the solar cells, allowing them to automatically slide down into a collection device. Collection is achieved without manual intervention or the aid of a robotic arm, reducing collection costs, facilitating operation, and increasing collection efficiency.

[0004] While the aforementioned patent reduces the need for manual or robotic assistance in collection, the height difference in the collection device means that when the battery cells fall into it, their edges are prone to strong collisions with the collection device, resulting in damage to the battery cells and rendering them unusable.

[0005] Therefore, how to provide an automatic cutting device for photovoltaic cells is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shown is a structural schematic of an automatic photovoltaic cell cutting device according to an embodiment of the present invention, comprising:

[0031] Workbench 1;

[0032] Storage box 10 is fixedly installed in the middle of the front end of workbench 1, and a storage slot 12 is provided at the bottom;

[0033] Separation block 11 is fixedly installed in the middle of storage box 10;

[0034] The receiving structure is movably set in the middle of the storage slot 12 for receiving the circuit board.

[0035] In this embodiment of the invention, when in use, the cut circuit board is placed in the storage box 10, and then separated by the action of the separating block 11, causing the circuit board to fall onto the receiving structure.

[0036] By setting a storage slot 12 at the bottom of the storage box 10, it is convenient to receive the separated circuit board. A receiving structure is set in the storage slot 12, thereby reducing the height difference between the circuit board and the bottom of the storage slot 12, which could lead to damage to the circuit board.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, a side baffle 2 is arrayed on the right side of the workbench 1, a transmission chain plate 5 is movably installed on the inner side of the side baffle 2, a pushing structure is arrayed on the surface of the transmission chain plate 5, a cutting frame 3 is fixedly installed in the middle of the side baffle 2, a laser cutter 4 is fixedly installed in the middle of the top of the cutting frame 3, and elastic centering structures are symmetrically arranged on both sides of the cutting frame 3 for centering the circuit board.

[0038] In this embodiment of the utility model, when in use, the transmission chain plate 5 pushes the circuit board to move through the pushing structure, and the elastic centering structure is used to center the circuit board, and then the laser cutter 4 performs the cutting.

[0039] By arraying a pushing structure on the transmission chain plate 5 and setting an elastic centering structure on both sides of the cutting frame 3, the circuit board can move centered on the transmission chain plate 5. Since the elastic centering structure is flexible, it can be adapted to circuit boards of various sizes, thereby expanding the application range of the cutting device.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the receiving structure includes a partition 13, a guide rod 15, a first spring 16, and a movable top plate 17.

The first spring 16 is movably sleeved on the surface of the guide rod 15 and movably abuts against the bottom of the movable top plate 17.

[0041] In this embodiment of the utility model, when in use, it falls onto the movable top plate 17 in the storage slots 12 on both sides, and applies pressure to the first spring 16 on the surface of the guide rod 15 in the movable slot 14 in the middle of the partition 13, so that the movable top plate 17 can change its descent height as the number of circuit boards increases.

[0042] By setting up a support structure, the height difference between the circuit board and the bottom of the storage slot 12 is reduced, thus preventing damage to the circuit board.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the elastic centering structure includes a groove 20, a slider 21 and an elastic top plate 22. The groove 20 is symmetrically opened at the inner ends of the left and right side baffles 2. The slider 21 is slidably disposed inside the groove 20 on the front and rear sides. The elastic top plate 22 is fixedly installed on the outer ends of the slider 21 on the front and rear sides.

[0044] In this embodiment of the invention, when the elastic top plate 22 is pressed, the slider 21 slides along the groove 20, thereby causing the elastic top plate 22 to contract as the circuit board moves, thus making it suitable for centering and cutting circuit boards of various sizes.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment of the present invention, the pushing structure includes a second spring 18, the surface of the transmission chain plate 5 is arrayed with grooves 23, and protrusions 19 are movably inserted inside the grooves 23, the second spring 18 is disposed inside the grooves 23 and movably abuts against the bottom of the protrusions 19.

[0046] In this embodiment of the invention, when the protrusion 19 is pressed, it retracts into the groove 23; when it is not pressed, it extends out, contacts the side of the circuit board, and pushes it to move.

[0047] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the front of the storage box 10 is detachable, and the separation block 11 is triangular in shape.

[0048] In this embodiment of the utility model, when in use, the front side of the storage box 10 is disassembled to facilitate the removal of the internal circuit board, and the separation block 11 is triangular in shape to facilitate the separation of the circuit board.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, a transfer platform 9 is provided on the left side of the workbench 1, a first transfer frame 6 and a second transfer frame 7 are provided at the front and rear ends of the top of the workbench 1 respectively, and a lifting suction cup 8 is provided at the bottom for transferring the circuit board.

[0050] In this embodiment of the utility model, when in use, a transfer table 9 is provided on the left side of the workbench 1, and then a first transfer frame 6 and a second transfer frame 7 are respectively provided at the front and rear ends of the top of the workbench 1, and a lifting suction cup 8 is provided at the bottom of each, thereby realizing the automated transfer of circuit board cutting.

[0051] The above embodiments of this utility model provide an automatic photovoltaic cell cutting device. When in use, the circuit board is placed on the transmission chain plate 5 inside the side baffle 2. Then, under the action of the protrusion 19, the circuit board is pushed into the cutting frame 3 and then contacts the elastic top plates 22 on both sides of the cutting frame 3. Under the constraint of the protrusion 19, the circuit board is pushed towards the middle and the circuit board is squeezed against the elastic top plate 22, so that the sliders 21 at both ends slide in the groove 20. This allows the elastic top plate 22 to adjust its thickness according to the width of the circuit board, so that the circuit board is centered on the transmission chain plate 5. Then, under the action of the laser cutter 4, the circuit board is cut into two halves.

[0052] Then, the lifting suction cup 8 on the first transfer frame 6 is activated to transfer the cut circuit board to the transfer table 9, and then to the working area of ​​the second transfer frame 7. After that, it is transferred to the storage box 10, and under the action of the separating block 11, the cut circuit board is separated from each other and falls onto the movable top plate 17 in the storage slots 12 on both sides. The first spring 16 on the surface of the guide rod 15 in the movable slot 14 in the middle of the partition 13 is pressed, so that the movable top plate 17 can change its descent height as the number of circuit boards increases, thereby reducing the height difference between the circuit board and the bottom of the storage slot 12, thus preventing the circuit board from being damaged.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
