Description

Technical Field

[0001] The present invention relates to the technical field of solar panel cutting, and particularly relates to a cutting device for photovoltaic solar panels and a cutting method thereof. Background Art

[0002] A photovoltaic solar panel is a device that uses solar energy to generate electricity, also known as a solar photovoltaic panel or a solar panel. It usually consists of a layer called a "thin film", which is usually made of polycarbonate or other materials. When sunlight shines on the photovoltaic solar panel, photons in the thin film excite electrons, and these electrons are then converted into an electric current. This electric current can be collected and used to provide electricity for households or the power grid. The photovoltaic solar panel can be installed on the ground or fixed to a building using brackets.

[0003] When cutting existing solar panels, the entire solar panel needs to be fixed on the cutting table first, and then cutting is carried out. During cutting, the solar panels on both sides of the cutting part are not fixed. During the process of cutting the solar panel in half, when the blade cuts, the cutting part of the solar panel will cause the solar panels on both sides to vibrate under the rotational cutting action of the cutting knife. If the entire solar panel is not firmly fixed, it may even shake. In this way, the solar panel will shift up and down or even left and right, resulting in the cutting position shifting, and the cutting stability is not high, making the cut surface not straight after cutting, and the solar panel cannot meet the cutting quality and precision requirements. Therefore, a cutting device that can improve cutting stability is needed to solve the above problems. Summary of the Invention

[0004] In view of the problem that the existing cutting device for a photovoltaic solar panel does not fix the two sides of the cutting part during cutting, resulting in unstable cutting of the solar panel, poor cutting accuracy, and low quality, the present invention is proposed.

[0005] Therefore, the object of the present invention is to provide a cutting device for a photovoltaic solar panel, and its purpose is to fix the two sides of the cutting part of the solar panel during cutting, making the cutting more stable and improving the cutting effect and quality.

[0006] To achieve the above object, the present invention provides the following technical solution: A cutting device for a photovoltaic solar panel, the device includes a cutting table, a photovoltaic panel disposed on the top of the cutting table, a cutting groove opened on the cutting table, a pressing component disposed on the cutting table, an adsorption component and an air inlet component disposed on the pressing component; the pressing component includes a cutting component and a pressing component disposed on the cutting table; The adsorption component is used to adsorb the photovoltaic panel during the pressing process of the pressing component; The air intake component is used to intake air when the cutting assembly moves upward, thereby unlocking the adsorption of the photovoltaic panel by the adsorption component.

[0007] As a preferred solution of the photovoltaic solar panel cutting device described in the present invention, the cutting assembly includes a vertical support plate arranged on the cutting table, two sliding columns arranged on one side of the vertical support plate, and a vertical power assembly arranged on one side of the vertical support plate.

[0008] As a preferred solution of the photovoltaic solar panel cutting device described in the present invention, wherein: a vertical movable plate is arranged on the other side of the vertical supporting plate, and one side of the vertical power assembly is transmission-connected to the vertical movable plate, and both sides of the vertical movable plate are slidingly connected to the sliding columns, a transverse power assembly is arranged on the top of the vertical movable plate, a cutting column is arranged at the bottom of the transverse power assembly, and a cutting knife is arranged at the bottom of the cutting column. During cutting, the vertical power assembly is started first, and the vertical movable plate is driven to move downward on the vertical supporting plate, and both sides of the vertical movable plate slide downward on the sliding columns. When the vertical movable plate descends to a certain position, the transverse power assembly is started to drive the cutting knife on the cutting column to move and cut from one side of the photovoltaic panel. When the cutting is completed, the vertical power assembly drives the vertical movable plate to move up, and the transverse power assembly drives the vertical movable plate to move horizontally and reset after moving up, so as to prepare for the next cutting.

[0009] As a preferred solution of a photovoltaic solar panel cutting device described in the present invention, the downward pressure component includes a convex block arranged at the bottom of the vertically movable plate, a movable cavity opened inside the convex block, and when the lateral power assembly is working, it drives the cutting column to slide in the movable cavity, downward pressure blocks arranged on both sides of the bottom of the convex block, limit strips arranged on both sides of the top of the inner cavity of the lower pressure block, and downward pressure plates arranged on both sides of the bottom of the convex block. The limit strips limit the downward pressure plates, so that when the downward pressure plates move up, they will drive the downward pressure blocks to move up, and the downward pressure plates arranged on the lower pressure plates An N-pole magnet on the plate, an S-pole magnet arranged in the middle of the inner cavity of the lower pressing block, a mounting plate arranged at the bottom of the convex block, a lower pressing column array arranged at the bottom of the mounting plate, and a suction cup arranged at the bottom of the lower pressing column. When the suction cup contacts the photovoltaic panel, when the convex block is pressed down, the mounting plates on both sides of the bottom of the convex block move downward inside the lower pressing block, and the downward movement of the N-pole magnet causes the mutual repulsion of the magnets to squeeze the entire lower pressing block, and the suction cup is squeezed on the surface of the photovoltaic panel, so that the two sides of the photovoltaic panel cut are squeezed and fixed, thereby improving the stability during cutting.

[0010] As a preferred solution of the photovoltaic solar panel cutting device described in the present invention, the adsorption component includes a cleaning component symmetrically arranged on both sides of the cutting column, a suction component arranged on one side of the cleaning component, and an exhaust component arranged on one side of the bottom of the lower pressing block.

[0011] As a preferred embodiment of the photovoltaic solar panel cutting device of the present invention, the following is provided: The cleaning component includes a cleaning block disposed on one side of the bottom of the cutting column, an air extraction chamber opened inside the cleaning block, cleaning pipes disposed on both sides of the bottom of the cleaning block. The air extraction chamber is in a convex shape, facilitating the suction of debris by the cleaning pipes. There is an air extraction pipe disposed on the top of the cleaning block, and sliding holes opened on both sides of the convex block. The air extraction pipe is slidably connected to the side wall of the sliding hole. During operation, the air extraction pipe sucks the air extraction chamber, causing the cleaning pipes on both sides to suck and clean the debris and dust generated during cutting, reducing the dispersion and accumulation of dust and debris, preventing the dust from being too large and dispersing out and being inhaled by personnel during cutting, and improving the cleanliness and safety of the device during cutting.

[0012] As a preferred embodiment of the photovoltaic solar panel cutting device of the present invention, the following is provided: The suction component includes a suction pipe disposed on one side of the cleaning block. One end face of the suction pipe is a vertical plane. There is a pressing block disposed on one side of the suction pipe. An adsorption groove is opened on one side of the bottom of the convex block. The adsorption groove has a certain curvature, and the curvature decreases from top to bottom. When the suction pipe slides downward in the adsorption groove, the distance between the suction pipe and the groove surface of the adsorption groove becomes smaller, causing the suction pipe to be gradually blocked. And there is a moving groove disposed at the bottom of the adsorption groove.

[0013] As a preferred embodiment of the photovoltaic solar panel cutting device of the present invention, the following is provided: The exhaust component includes an exhaust hole opened on one side of the bottom of the moving groove, an exhaust plate disposed on one side of the exhaust hole, air outlet holes opened on the exhaust plate. The air outlet holes are arranged in an annular array on the exhaust plate. There is a connecting column disposed on one side of the exhaust plate, a spring sleeved on the connecting column, and one side of the spring is fixedly connected to the exhaust plate. There is a sealing plate disposed on the other side of the spring, and the middle of the sealing plate is slidably connected to the connecting column. There is an annular plate disposed on one side of the exhaust hole, and the inner side wall of the annular plate abuts against the sealing plate. And there is a communication hole opened in the pressing column. When the suction pipe is aligned with the exhaust plate, the diameter of the suction pipe is larger than the diameter of the exhaust plate, and the air outlet holes on the exhaust plate can be completely covered. The sealing plate is pulled, causing a gap to be generated between the sealing plate and the annular plate, facilitating the extraction of gas.

[0014] As a preferred embodiment of the photovoltaic solar panel cutting device of the present invention, the following is provided: The air intake component includes a sliding-out groove opened on the top of the moving groove, and an air intake assembly disposed on one side of the moving groove; The air intake assembly includes an air intake hole opened on one side of the moving groove, a blocking block disposed on the surface of the air intake hole, a rotating column disposed on one side of the blocking block, and a torsion spring disposed between the rotating column and the blocking block. When no force is applied to the torsion spring, the blocking block completely blocks the air intake hole. When one side of the blocking block is squeezed, the blocking block rotates around the rotating column, causing the air intake hole to be exposed and allowing gas to enter.

[0015] The present invention also provides a cutting device and a cutting method for a photovoltaic solar panel, aiming to: improve the stability during cutting and the fixing effect on both sides of the solar panel during cutting, so as to improve the cutting quality and efficiency.

[0016] To achieve the above object, the present invention provides the following technical solutions: A cutting method for a photovoltaic solar panel, comprising the following steps: S1: When cutting the photovoltaic panel, place the photovoltaic panel on the cutting table, start the vertical power assembly to make the vertical moving plate move downward on the vertical support plate, so that the convex block moves downward. During the moving process, the repulsive force of the S - pole magnets on both sides of the bottom of the convex block against the N - pole magnets causes the pressing block to squeeze the two sides of the cutting position of the photovoltaic panel downward, so that the suction cup discharges the internal air and presses against the photovoltaic panel, squeezing and fixing the two sides of the cutting position of the photovoltaic panel. S2: Start the air extractor connected to the air extraction pipe while starting the vertical power assembly. During the downward extrusion of the pressing block, the air extraction pipe extracts air from the air extraction cavity, and the air extraction pipe slides downward in the adsorption groove. When the cutting knife descends to the appropriate cutting position, the air extraction pipe just reaches and covers the exhaust plate, so that the air extraction pipe sucks the gas at the bottom of the pressing block. When the air extraction pipe leaves the exhaust plate, the sealing plate reseals the inside of the pressing block under the action of the spring restoring to its original length. S3: When the air extraction pipe sucks, the sealing plate is pulled and moved backward to compress the spring, leaving a gap between the annular plate and the sealing plate, so that the gas is sucked out. At this time, the suction cup adsorbs on the surface of the photovoltaic panel. Start the horizontal power assembly to make the cutting knife start cutting from one side of the photovoltaic panel. During the moving cutting, the air extraction pipe moves in the moving groove. At this time, the air extraction pipe is blocked, and the suction force is transferred to the cleaning pipes on both sides of the bottom of the cleaning block. The cleaning pipes start to extract and clean the debris and dust generated before and after cutting during cutting, reducing the dispersion of debris and dust. S4: When cutting to the other side of the photovoltaic panel, the extrusion plate squeezes one side of the stopper to make the stopper rotate around the rotating column, and the air inlet hole leaks out, and the gas enters the inside of the pressing block, so that the suction cup does not adsorb on the surface of the photovoltaic panel. The vertical power assembly moves to make the convex block move upward. Under the action of magnetic repulsive force, the two sides of the convex block slide upward in the pressing block, and the air extraction pipe slides upward in the sliding groove. When the lower pressing plate moves upward to a certain position to drive the pressing block to move upward, the horizontal power assembly starts to make the cutting knife return to its original position. During the process of returning to move, the air extraction pipe moves out of the sliding groove and sucks and cleans the inner sides of the pressing block and the convex block, so that the dust flying and accumulating on the side of the pressing block and the convex block is sucked away, avoiding the damage of the machine caused by long - term accumulation.

[0017] The beneficial effects of the present invention: When the cutting plate is downwards cutting the photovoltaic panel, under the mutual repulsion between the S-pole magnet and the N-pole magnet, the downward pressing blocks on both sides drive the suction cups to squeeze and fix the two sides of the cutting position of the photovoltaic panel, avoiding the shaking of the photovoltaic panels on both sides during the cutting process, resulting in the deviation of the cutting position, and improving the cutting stability and cutting quality.

[0018] While the suction cup is squeezing and fixing the photovoltaic panel, air is sucked through the suction tube to the air outlet so that the suction cup can be tightly attached to the surface of the photovoltaic panel, thereby further improving the stability of the squeezing and fixing, avoiding the photovoltaic panel from shaking during cutting, enhancing the accuracy of the cutting position, avoiding the cutting board from being offset and causing damage to other parts of the photovoltaic panel, and improving the cutting yield.

[0019] The air leakage hole is allowed to leak out by squeezing one side of the block, so that the suction cup does not adsorb the photovoltaic panel after the gas enters, thereby preventing the suction cup from adsorbing the photovoltaic panel when it is raised and causing damage to the photovoltaic panel. The suction cup's adsorption function on the photovoltaic panel is automatically unlocked, with a simple structure and high efficiency.

[0020] The suction pipe moves out of the slide-out slot and performs suction cleaning on the inner sides of the lower pressing block and the convex block, so that the dust flying and accumulated on the sides of the lower pressing block and the convex block during cutting is sucked away, thus avoiding damage to the machine caused by long-term accumulation.

DETAILED DESCRIPTION Example

[0030] Reference Figure 1-4 , which is the first embodiment of the present invention, provides a photovoltaic solar panel cutting device, which includes a cutting table 2, a photovoltaic panel 1 placed on the top of the cutting table 2, a cutting groove opened on the cutting table 2, a pressing component installed on the cutting table 2, an adsorption component and an air intake component installed on the pressing component; the adsorption component can be a suction cup 49 and a negative pressure pump connected to one end of the suction cup 49, the negative pressure pump extracts the air in the suction cup 49 so that the suction cup 49 adsorbs the surface of the photovoltaic panel 1, the air intake component can be an air pump installed on one side of the pressing block 43, injects air into the closed cavity at the bottom of the pressing block 43 so that the internal pressure becomes normal, thereby unlocking the adsorption effect of the suction cup 49 on the photovoltaic panel 1, the pressing component includes a cutting assembly 3 and a pressing assembly 4 installed on the cutting table 2, the cutting assembly 3 includes a vertical support plate 31 fixedly connected to the cutting table 2, two sliding columns 32 fixedly connected to one side of the vertical support plate 31, and a vertical power assembly 33 fixedly connected to one side of the vertical support plate 31.

[0031] On the other side of the vertical support plate 31, there is a vertically movable plate 34 slidably connected. One side of the vertical power assembly 33 is drivingly connected to the vertically movable plate 34. The two sides of the vertically movable plate 34 are slidably connected to the sliding columns 32. A transverse power assembly 35 is installed on the top of the vertically movable plate 34. A cutting column 36 is fixedly connected to the bottom of the transverse power assembly 35. And a cutting knife 37 is rotatably connected to the bottom of the cutting column 36. During cutting, the vertical power assembly 33 starts first. The vertically movable plate 34 is driven to move downward on the vertical support plate 31. The two sides of the vertically movable plate 34 slide downward on the sliding columns 32. When the vertically movable plate 34 descends to a certain position, the transverse power assembly 35 starts to drive the cutting knife 37 on the cutting column 36 to move and cut from one side of the photovoltaic panel 1. When the cutting is completed, the vertical power assembly 33 drives the vertically movable plate 34 to move upward. The transverse power assembly 35 drives the vertically movable plate 34 after upward movement to move horizontally and reset, preparing for the next cutting.

[0032] The pressing-down assembly 4 includes a convex block 41 fixedly connected to the bottom of the vertically movable plate 34. A moving cavity is opened inside the convex block 41. When the transverse power assembly 35 works, it drives the cutting column 36 to slide in the moving cavity. Pressing-down blocks 43 are slidably connected to both sides of the bottom of the convex block 41. Limiting strips 44 are fixedly connected to both sides of the top of the inner cavity of the pressing-down blocks 43. Lower pressing plates 45 are fixedly connected to both sides of the bottom of the convex block 41. The limiting strips 44 limit the lower pressing plates 45, so that when the lower pressing plates 45 move upward, they will drive the pressing-down blocks 43 to move upward. N-pole magnets 46 are fixedly connected to the lower pressing plates 45. S-pole magnets 48 are fixedly connected to the middle of the inner cavity of the pressing-down blocks 43. Mounting plates 47 are fixedly connected to the bottom of the convex block 41. Pressing-down columns 42 are fixedly connected to the bottom of the mounting plates 47 in an array. And suction cups 49 are fixedly connected to the bottom of the pressing-down columns 42. When the suction cups 49 contact the photovoltaic panel 1, when the convex block 41 presses down, the mounting plates 47 on both sides of the bottom of the convex block 41 move downward inside the pressing-down blocks 43. The downward movement of the N-pole magnets causes the repulsive force of the magnets to squeeze the entire pressing-down blocks 43. The suction cups 49 are squeezed on the surface of the photovoltaic panel 1, squeezing and fixing both sides of the cutting position of the photovoltaic panel 1, improving the stability during cutting.

[0033] During the working process, when cutting the photovoltaic panel 1, the photovoltaic panel 1 is placed on the cutting table 2. The vertical power assembly 33 is started to make the vertically movable plate 34 move downward on the vertical support plate 31, so that the convex block 41 moves downward. During the movement, the repulsive force of the S-pole magnets 48 on both sides of the bottom of the convex block 41 on the N-pole magnets 46 causes the pressing-down blocks 43 to squeeze both sides of the cutting position of the photovoltaic panel 1 downward, so that the suction cups 49 discharge the air inside and squeeze on the photovoltaic panel 1, squeezing and fixing both sides of the cutting position of the photovoltaic panel 1. When the cutting plate cuts the photovoltaic panel 1 downward, under the mutual repulsive force of the S-pole magnet and the N-pole magnet 46, the pressing blocks 43 on both sides drive the suction cups 49 to squeeze and fix both sides of the cutting position of the photovoltaic panel 1, avoiding the jitter of the photovoltaic panels 1 on both sides during the cutting process, resulting in the deviation of the cutting position, and improving the cutting stability and cutting quality. Embodiment

[0034] Refer to Figure 1-6 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adsorption component includes a cleaning component 5 symmetrically installed on both sides of the cutting column 36, a suction component 6 installed on one side of the cleaning component 5, and an exhaust component 7 installed on one side of the bottom of the pressing block 43. The cleaning component 5 includes a cleaning block 51 fixedly connected to one side of the bottom of the cutting column 36, an air extraction cavity 52 opened inside the cleaning block 51, cleaning pipes 53 fixedly connected to both sides of the bottom of the cleaning block 51. The shape of the air extraction cavity 52 is convex, which is convenient for the cleaning pipes 53 to suck debris. A suction pipe 54 fixedly connected to the top of the cleaning block 51, and sliding holes 55 opened on both sides of the convex block 41, and the suction pipe 54 is slidably connected to the side wall of the sliding hole 55. During operation, the suction pipe 54 sucks the air extraction cavity 52, so that the cleaning pipes 53 on both sides suck and clean the debris and dust generated by cutting, reducing the dispersion and accumulation of dust and debris, avoiding too much dust floating out and being inhaled by personnel during cutting, and improving the cleanliness and safety of the device cutting.

[0035] The suction component 6 includes a suction pipe 61 fixedly connected to one side of the cleaning block 51. One end face of the suction pipe 61 is a vertical surface, a pressing block 62 fixedly connected to one side of the suction pipe 61, an adsorption groove 63 opened on one side of the bottom of the convex block 41. The adsorption groove 63 has a certain arc, and the arc becomes smaller and smaller from top to bottom. When the suction pipe 61 slides downward in the adsorption groove 63, the distance between the suction pipe 61 and the groove surface of the adsorption groove 63 becomes smaller and smaller, so that the suction pipe 61 is slowly blocked, and a moving groove 64 opened at the bottom of the adsorption groove 63.

[0036] The exhaust assembly 7 includes an exhaust hole 71 opened on one side of the bottom of the movable groove 64, an exhaust plate 72 fixedly connected to one side of the exhaust hole 71, an exhaust hole 73 opened on the exhaust plate 72, the exhaust holes 73 are opened on the exhaust plate 72 in an annular array, a connecting column 74 fixedly connected to one side of the exhaust plate 72, a spring 75 sleeved on the connecting column 74, and one side of the spring 75 is fixedly connected to the exhaust plate 72, and a sealing plate 76 fixedly connected to the other side of the spring 75, and the middle of the sealing plate 76 is fixedly connected to the exhaust plate 72. The part is slidably connected with the connecting column 74, and is fixedly connected to the annular plate 77 on one side of the exhaust hole 71, and the inner wall of the annular plate 77 is in contact with the sealing plate 76, as well as the connecting hole 78 opened in the lower pressure column 42. When the suction pipe 61 is aligned with the exhaust plate 72, the diameter of the suction pipe 61 is larger than the diameter of the exhaust plate 72, and the air outlet hole 73 on the exhaust plate 72 can be completely covered, and the sealing plate 76 is pulled, so that a gap is generated between the sealing plate 76 and the annular plate 77, which facilitates the gas to be extracted.

[0037] During operation, the vacuum pump connected to the vacuum pipe 54 is started at the same time as the vertical power assembly 33 is started. During the downward squeezing of the lower pressing block 43, the vacuum pipe 54 evacuates the vacuum chamber 52, and the suction pipe 61 slides downward in the adsorption groove 63. When the cutting knife 37 descends to a suitable cutting position, the suction pipe 61 just reaches and covers the exhaust plate 72, so that the suction pipe 61 sucks the gas at the bottom of the lower pressing block 43. When the suction pipe 61 leaves the exhaust plate 72, the sealing plate 76 re-seals the interior of the lower pressing block 43 under the force of the spring 75 restoring its original length; the suction pipe 61 During suction, the sealing plate 76 is pulled back and the spring 75 is compressed, leaving a gap between the annular plate 77 and the sealing plate 76, so that the gas is sucked out. At this time, the suction cup 49 is adsorbed on the surface of the photovoltaic panel 1, and the lateral power assembly 35 is started to make the cutting knife 37 start cutting from one side of the photovoltaic panel 1. During mobile cutting, the suction pipe 61 moves in the moving groove 64. At this time, the suction pipe 61 is blocked, and the suction force is transferred to the cleaning pipes 53 on both sides of the bottom of the cleaning block 51. The cleaning pipes 53 start to vacuum and clean the debris and dust generated before and after the cutting, so as to reduce the dispersion of the debris and dust; While the suction cup 49 squeezes and fixes the photovoltaic panel 1, the suction pipe 61 is aligned with the air outlet 73 to evacuate air so that the suction cup 49 can be tightly adsorbed on the surface of the photovoltaic panel 1, thereby further improving the stability of the squeezing and fixing, avoiding the photovoltaic panel 1 from shaking during cutting, enhancing the accuracy of the cutting position, avoiding the cutting board from being offset and causing damage to other parts of the photovoltaic panel 1, and improving the cutting yield.

[0038] The remaining structures are the same as those of Example 1. Example

[0039] Reference Figure 1-8, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the intake component includes a sliding-out groove 8 opened at the top of the moving groove 64, an intake assembly 9 installed on one side of the moving groove 64. The intake assembly 9 includes an intake hole 91 opened on one side of the moving groove 64, a stopper 92 abutted against the surface of the intake hole 91, a rotating column 93 fixedly connected to one side of the stopper 92, and a torsion spring installed between the rotating column 93 and the stopper 92. When no force is applied to the torsion spring, the stopper 92 completely blocks the intake hole 91. When one side of the stopper 92 is squeezed, the stopper 92 rotates around the rotating column 93, causing the intake hole 91 to be exposed and allowing gas to enter.

[0040] During the working process, when the other side of the photovoltaic panel 1 is cut, the pressing plate squeezes one side of the stopper 92, causing the stopper 92 to rotate around the rotating column 93, and the intake hole 91 is exposed. Gas enters the interior of the lower pressing block 43, causing the suction cup 49 not to adsorb on the surface of the photovoltaic panel 1. The vertical power assembly 33 moves, causing the convex block 41 to move upward. Under the repulsive force of magnetism, both sides of the convex block 41 slide upward within the lower pressing block 43. The suction pipe 61 slides upward within the sliding-out groove 8. When the lower pressing plate 45 moves upward to a certain position, it drives the lower pressing block 43 to move upward. The transverse power assembly 35 is activated, causing the cutting knife 37 to return to its original position. During the process of returning to move, the suction pipe 61 moves out of the sliding-out groove 8 and sucks and cleans the inner sides of the lower pressing block 43 and the convex block 41, sucking away the dust accumulated on the sides of the lower pressing block 43 and the convex block 41 caused by cutting and flying, avoiding damage to the machine caused by long-term accumulation. By squeezing one side of the stopper 92, the air leakage hole is exposed, allowing gas to enter. After the gas enters, the suction cup 49 does not adsorb the photovoltaic panel 1, avoiding the suction cup 49 sucking up the photovoltaic panel 1 when it rises and causing damage to the photovoltaic panel 1. Moreover, the automatic unlocking of the adsorption function of the suction cup 49 on the photovoltaic panel 1 is realized, with a simple structure and high efficiency.

[0041] The remaining structures are the same as those in Embodiment 2. Embodiment

[0042] Referring to Figure 1-8 , which is the fourth embodiment of the present invention, provides a method for cutting a photovoltaic solar panel, including the following steps: S1: When cutting the photovoltaic panel 1, place the photovoltaic panel 1 on the cutting table 2, and start the vertical power assembly 33 to make the vertical moving plate 34 move downward on the vertical support plate 31, causing the convex block 41 to move downward. During the movement, the repulsive force of the S-pole magnets 48 on both sides of the bottom of the convex block 41 against the N-pole magnet 46 causes the lower pressing block 43 to squeeze both sides of the cutting position of the photovoltaic panel 1 downward, causing the suction cup 49 to discharge the internal air and squeeze against the photovoltaic panel 1, squeezing and fixing both sides of the cutting position of the photovoltaic panel 1. S2: While starting the vertical power assembly 33, start the air extractor connected to the air extraction pipe 54. During the downward extrusion of the lower pressing block 43, the air extraction pipe 54 extracts air from the air extraction chamber 52. The air extraction pipe 61 slides downward in the adsorption groove 63. When the cutting knife 37 descends to a suitable cutting position, the air extraction pipe 61 just reaches and covers the exhaust plate 72, so that the air extraction pipe 61 sucks the gas at the bottom of the lower pressing block 43. When the air extraction pipe 61 leaves the exhaust plate 72, the sealing plate 76 reseals the inside of the lower pressing block 43 under the action of the spring 75 restoring its original length; S3: When the air extraction pipe 61 sucks air, the sealing plate 76 is pulled and moved backward to compress the spring 75, and there is a gap between the annular plate 77 and the sealing plate 76, so that the gas is sucked out. At this time, the suction cup 49 adsorbs on the surface of the photovoltaic panel 1. Start the horizontal power assembly 35 to make the cutting knife 37 start cutting from one side of the photovoltaic panel 1. During the moving cutting, the air extraction pipe 61 moves in the moving groove 64. At this time, the air extraction pipe 61 is blocked, and the suction force is transferred to the cleaning pipes 53 on both sides of the bottom of the cleaning block 51. The cleaning pipes 53 start to extract and clean the debris and dust generated before and after cutting during cutting, reducing the dispersion of debris and dust; S4: After cutting to the other side of the photovoltaic panel 1, the extrusion plate squeezes one side of the stopper 92, causing the stopper 92 to rotate around the rotating column 93, and the air inlet hole 91 is exposed. The gas enters the inside of the lower pressing block 43, so that the suction cup 49 does not adsorb on the surface of the photovoltaic panel 1. The vertical power assembly 33 moves to make the convex block 41 move upward. Under the repulsive force of magnetism, both sides of the convex block 41 slide upward in the lower pressing block 43. The air extraction pipe 61 slides upward out of the sliding groove 8. When the lower pressing plate 45 moves upward to a certain position, it drives the lower pressing block 43 to move upward. The horizontal power assembly 35 is started to make the cutting knife 37 return to its original position. During the process of returning to move, the air extraction pipe 61 moves out of the sliding groove 8 and sucks and cleans the inner sides of the lower pressing block 43 and the convex block 41, so that the dust flying and accumulating on the sides of the lower pressing block 43 and the convex block 41 is sucked away, avoiding damage to the machine caused by long-term accumulation.

10. A photovoltaic solar panel cutting method according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When cutting the photovoltaic panel (1), the photovoltaic panel (1) is placed on the cutting table (2), and the vertical power assembly (33) is started to move the vertical moving plate (34) downward on the vertical support plate (31), so that the convex block (41) moves downward. During the movement, the repulsive force of the S-pole magnets (48) on the N-pole magnets (46) on the two sides of the bottom of the convex block (41) causes the pressing block (43) to press the two sides of the cutting position of the photovoltaic panel (1) downward, so that the suction cup (49) discharges the internal air and presses it on the photovoltaic panel (1), thereby pressing and fixing the two sides of the cutting position of the photovoltaic panel (1); S2: while starting the vertical power assembly (33), the vacuum machine connected to the vacuum pipe (54) is started. When the lower pressing block (43) is pressed downward, the vacuum pipe (54) vacuums the vacuum chamber (52). The suction pipe (61) slides downward in the adsorption groove (63). When the cutting knife (37) descends to a suitable cutting position, the suction pipe (61) just reaches and covers the exhaust plate (72), so that the suction pipe (61) vacuums the gas at the bottom of the lower pressing block (43). When the suction pipe (61) leaves the exhaust plate (72), the sealing plate (76) re-seals the interior of the lower pressing block (43) under the action of the spring (75) to restore its original length. S3: When the suction pipe (61) is sucking, the sealing plate (76) is pulled back and the spring (75) is compressed, leaving a gap between the annular plate (77) and the sealing plate (76) so that the gas is sucked out. At this time, the suction cup (49) is adsorbed on the surface of the photovoltaic panel (1), and the lateral power assembly (35) is started so that the cutting knife (37) starts cutting from one side of the photovoltaic panel (1). When moving and cutting, the suction pipe (61) moves in the moving groove (64). At this time, the suction pipe (61) is blocked, and the suction force is transferred to the cleaning pipes (53) on both sides of the bottom of the cleaning block (51). The cleaning pipes (53) start to exhaust and clean the debris and dust generated before and after the cutting, thereby reducing the dispersion of the debris and dust; S4: After cutting to the other side of the photovoltaic panel (1), the extrusion plate squeezes one side of the stopper (92) so that the stopper (92) rotates around the rotating column (93), the air inlet (91) leaks out, and the gas enters the interior of the lower pressing block (43), so that the suction cup (49) does not adsorb to the surface of the photovoltaic panel (1), and the vertical power assembly (33) moves so that the convex block (41) moves upward. Under the action of the magnetic repulsive force, the two sides of the convex block (41) slide upward in the lower pressing block (43), and the suction pipe (61) slides upward. The cutting blade (37) slides upwards out of the slot (8), moves to a certain position on the lower pressing plate (45), drives the lower pressing block (43) to move upwards, and the transverse power assembly (35) is started to restore the cutting blade (37) to its original position. During the restoration movement, the suction pipe (61) moves out of the slot (8) and performs suction cleaning on the inner sides of the lower pressing block (43) and the convex block (41), so that the dust accumulated on the sides of the lower pressing block (43) and the convex block (41) during cutting is sucked away, thereby avoiding damage to the machine caused by long-term accumulation.
