AI Technical Summary
Existing laser slicing machines tend to produce uneven cuts when cutting solar photovoltaic cells, affecting smoothness and making it difficult to effectively separate the molten material from the photovoltaic cell.
By introducing a support column and an electromagnet system into the laser slicing machine, the position of the support column is controlled to change with the laser beam emitting head, so that the cutting edge is suspended in the air. The electromagnet is used to attract the support column and separate it from the photovoltaic cell, avoiding the adhesion of molten material and ensuring the smoothness of the cut.
This improved the smoothness of the cut edges of solar photovoltaic cells, preventing the molten material from sticking to the photovoltaic cells and ensuring the cutting quality.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser slicing machine technology, and in particular relates to a laser slicing machine for solar photovoltaic cells. Background Technology
[0002] Solar power generation is divided into solar thermal power generation and photovoltaic power generation. The solar power generation usually refers to solar photovoltaic power generation. Modern solar lights require photovoltaic panels to provide electricity, as do some colored lights. These photovoltaic panels require relatively low power and voltage, so they need to be cut and then welded together using welding wire.
[0003] Most existing solar photovoltaic cells are cut using laser slicing machines. Since the cutting platform of the laser slicing machine has longitudinal and transverse cutting lines, and the size of the solar photovoltaic cell is not fixed, the cut cannot fully coincide with the cutting lines. This makes it difficult for the rapidly melting material to separate from the photovoltaic cell during laser cutting, resulting in an uneven cut and affecting the smoothness of the cut.
[0004] Therefore, a laser slicing machine for solar photovoltaic cells is proposed. Utility Model Content
[0005] This invention provides a laser slicing machine for solar photovoltaic cells, aiming to solve the above-mentioned problems.
[0006] This utility model is implemented as follows: a laser slicing machine for solar photovoltaic cells includes: a laser slicing machine body; a partition plate welded to the inner wall of the laser slicing machine body; a limiting hole opened at the top of the partition plate; a limiting post penetrating inside the limiting hole; a support post integrally formed on the top of the limiting post; a retaining ring fixed to the outer wall of the limiting post near the position above the limiting hole; a retaining plate integrally formed on the bottom end of the limiting post; an iron sheet welded to the center position at the bottom of the retaining plate; an electromagnet embedded and fixed to the bottom of the laser slicing machine body near the position directly below the iron sheet; a spring fixed between the bottom of the laser slicing machine body and the retaining plate; a movable frame disposed on the top of the laser slicing machine body; a laser beam emitting head disposed on the outer wall of the movable frame; an infrared emitter fixed to the top of the laser beam emitting head; a fixing plate fixed to the top of the laser slicing machine body near the side of the movable frame by bolts; a top plate welded to the top of the fixing plate; and an infrared receiver embedded and fixed to the bottom of the top plate near the position directly above the electromagnet.
[0007] Preferably, the outer diameters of both the retaining ring and the retaining plate are larger than the inner diameter of the limiting hole.
[0008] Preferably, after the electromagnet is energized and generates magnetism, it is magnetically attracted to the iron sheet.
[0009] Preferably, the limiting hole, limiting post, support post, retaining ring, retaining plate, iron sheet, electromagnet, spring and infrared receiver are all on the same vertical axis, and the electromagnet and infrared receiver on the same vertical axis are matched and correspond to each other.
[0010] Preferably, the fixing plate and the laser slicer body are horizontal.
[0011] Preferably, the support column has a frustum structure.
[0012] Compared with the prior art, the embodiments of this application have the following main advantages:
[0013] By controlling the support column below the solar photovoltaic panel to rise and fall with the position of the laser beam emitter, the support column at the cutting point can be separated from the solar photovoltaic panel when the laser beam emitter cuts the solar photovoltaic panel. The cutting point of the solar photovoltaic panel is in a suspended state. The existence of space makes it easy for the molten material to be blown away to be fully separated from the cutting point of the solar photovoltaic panel, thereby avoiding the molten material from sticking to the photovoltaic panel during laser cutting and affecting the smoothness of the cutting point, thus ensuring the quality of the cutting.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0022] This utility model embodiment provides a laser slicing machine for solar photovoltaic cells, such as... Figure 1-5 As shown, the laser slicer includes a laser slicer body 1. A partition 2 is welded to the inner wall of one side of the laser slicer body 1. A limit hole 3 is opened at the top of the partition 2. A limit post 4 passes through the interior of the limit hole 3. A support post 5 is integrally formed at the top of the limit post 4. The support post 5 has a frustum structure. A retaining ring 6 is fixedly installed on the outer wall of one side of the limit post 4 near the position above the limit hole 3. A baffle 7 is integrally formed at the bottom of the limit post 4. An iron plate 8 is welded to the center of the bottom of the baffle 7. An electromagnet 9 is fixedly installed at the bottom of the laser slicer body 1 near the position directly below the iron plate 8. The bottom of the laser slicer body 1 is also fixedly installed. A spring 10 is fixedly installed between the baffle plate 7 and the inner side of the iron plate 8 and the electromagnet 9. A movable frame 11 is installed on the top of the laser slicer body 1. A laser beam emitter 12 is installed on the movable frame 11. An infrared emitter 13 is fixedly connected to the top of the laser beam emitter 12 by screws. A fixing plate 14 is fixedly connected to the top of the laser slicer body 1 near the movable frame 11 by bolts. The fixing plate 14 is horizontal with the laser slicer body 1. A top plate 15 is welded to the top of the fixing plate 14. An infrared receiver 16 is embedded and fixed at the bottom of the top plate 15 near the position directly above the electromagnet 9.
[0023] It should be noted that, because the cutting platform of the laser slicing machine has longitudinally and transversely arranged cutting lines, and the cutting size of the solar photovoltaic cell is not fixed, the cutting point cannot fully coincide with the cutting lines. This makes it difficult for the rapidly molten material to separate from the photovoltaic cell during laser cutting, resulting in an uneven cut and affecting the smoothness of the cut. In this embodiment, by controlling the support column 5 under the solar photovoltaic cell to rise and fall with the position of the laser beam emitting head 12, the support column 5 at the cutting point can be separated from the solar photovoltaic cell when the laser beam emitting head 12 cuts the solar photovoltaic cell. The cutting point of the solar photovoltaic cell is in a suspended state. The existence of space facilitates the separation of the molten material blown away from the cutting point of the solar photovoltaic cell, thereby avoiding the molten material from sticking to the photovoltaic cell during laser cutting and affecting the smoothness of the cut, thus ensuring the quality of the cut.
[0024] Specifically, in this embodiment, the solution mainly includes support columns 5. During use, the solar photovoltaic panel is placed on the laser slicer body 1, and the solar photovoltaic panel presses against several support columns 5. The support columns 5 move downwards under pressure, and the limiting holes 3 guide the limiting columns 4, causing the limiting columns 4 to move downwards synchronously. The spring 10 is compressed, and the support columns 5 move downwards a certain distance. The height difference between the pressed support columns 5 and the unpressed support columns 5 keeps the solar photovoltaic panel confined within the space formed by the unpressed support columns 5, preventing the solar photovoltaic panel from shifting position during cutting and ensuring stability during cutting. When laser cutting is performed, the laser beam emitting head 12 moves laterally and longitudinally above the solar photovoltaic panel, emitting laser rays. When cutting solar photovoltaic panels, as the laser beam emitting head 12 moves, the infrared emitter 13 on top of the laser beam emitting head 12 moves synchronously. When the infrared rays emitted by the infrared emitter 13 are received by the infrared receiver 16, the external PLC controller controls the electromagnet 9, which is in a corresponding state and on the same vertical axis as the infrared receiver 16, to be energized. After the electromagnet 9 is energized and generates magnetism, it uses magnetic attraction to attract the iron plate 8 to move downward. During the downward movement of the iron plate 8, the limiting post 4 and the support post 5 move downward synchronously. The support post 5 separates from the solar photovoltaic panel. At this time, when the laser beam emitting head 12 cuts the solar photovoltaic panel, the cut part of the solar photovoltaic panel is in a suspended state, thereby avoiding the molten material during laser cutting from sticking to the photovoltaic panel and affecting the smoothness of the cut.
[0025] In a further preferred embodiment of this utility model, such as Figure 2-4 As shown, the outer diameters of the retaining ring 6 and the retaining plate 7 are both larger than the inner diameter of the limiting hole 3. The limiting hole 3, the limiting post 4, the support post 5, the retaining ring 6, the retaining plate 7, the iron plate 8, the electromagnet 9, the spring 10 and the infrared receiver 16 are all on the same vertical axis. The electromagnet 9 and the infrared receiver 16 on the same vertical axis are matched and correspond to each other.
[0026] In this embodiment, the difference in inner diameter prevents the retaining ring 6 and the retaining plate 7 from passing through the limiting hole 3, thereby preventing the limiting post 4 from falling off. By using the setting on the same vertical axis, the stability of the limiting post 4 in limiting the lifting and lowering can be guaranteed, ensuring that the limiting post 4 lifts and lowers vertically. Furthermore, by matching the electromagnet 9 with the infrared receiver 16, the corresponding electromagnet 9 can be controlled to be energized and operated.
[0027] In a further preferred embodiment of this utility model, such as Figure 4 As shown, after the electromagnet 9 is energized and generates magnetism, it is connected to the iron sheet 8 by magnetic attraction.
[0028] In this embodiment, after the electromagnet 9 is energized and generates magnetism, the iron sheet 8 is attracted and moved downward by the magnetic attraction. During the downward movement of the iron sheet 8, the limiting post 4 and the support post 5 move downward synchronously, and the support post 5 separates from the solar photovoltaic cell.
