[0002] POE encapsulation photovoltaic film is mainly used for the encapsulation of high-efficiency photovoltaic modules such as double-glass modules and N-type battery modules. In order to observe the internal structure of POE encapsulation photovoltaic film, such as the distribution of each layer, thickness uniformity, etc., and thus evaluate its manufacturing quality, it is necessary to grind the cross section of POE encapsulation photovoltaic film.

[0003] A patent with publication number CN221313642U discloses a photovoltaic encapsulation film cross-section grinding device, including a workbench, the top surface of which is rotatably connected to a grinding disc, and the four corners of the bottom surface are fixed with support legs; the above-mentioned photovoltaic encapsulation film cross-section grinding device can automatically adjust the height of the clamping plate during the grinding process, thereby increasing the stability of the photovoltaic film sample during grinding.

[0004] When the existing photovoltaic encapsulation film cross-section grinding device is in use, the user manually positions the photovoltaic film sample directly below the clamping plate. When the operator manually places the photovoltaic film sample, due to limitations of visual judgment, hand movements and other factors, the positioning of the photovoltaic film sample is inaccurate, resulting in a slight deviation in the placement position, causing the photovoltaic film sample to shift or tilt during the grinding process, resulting in reduced grinding efficiency and poor grinding effect.

At this time, the clamping plate can position and place the photovoltaic film sample. When grinding the photovoltaic film sample, the baffle is driven to block one side of the placement plate, and the clamping plate presses down the photovoltaic film sample and performs grinding operations through the grinding belt.

[0008] As a further description of the above technology, a POE encapsulation photovoltaic film cross-section grinding tool: The clamping plate is fixedly connected with an electric cylinder, and the telescopic end of the electric cylinder is fixedly connected to the inside of the rack.

[0009] As a further description of the above technology, a POE encapsulation photovoltaic film cross-section grinding tool: The interior of the baffle is slidably connected with a piston plate, the outer wall of the baffle is provided with a plurality of air inlet holes, the interior of the baffle is fixedly connected with a fixing plate, and a fixing spring is fixedly connected between the piston plate and the inner wall of the fixing plate.

[0010] As a further description of the above technology, a POE encapsulation photovoltaic film cross-section grinding tool: A fixing rod is fixedly connected to one side of the clamping plate, and the fixing rod is located on the inner side of the rotating rod. An electromagnet is fixedly connected inside the fixing rod, and a magnetic rod is fixedly connected to the upper surface of the piston plate.

[0016] In summary, due to the use of the above-mentioned technology, a POE encapsulation photovoltaic film cross-section grinding tooling has the following beneficial effects: 1. By providing a baffle, when it is necessary to place the photovoltaic film sample, the baffle can be driven to rotate so that an opening is formed on one side of the clamping plate, and then the staff can position and place the photovoltaic film sample through the placement groove inside the clamping plate. After the positioning and placement operation, the baffle is driven to reset, and the baffle blocks one side of the placement groove. The clamping plate and the baffle fix the photovoltaic film sample, and the grinding belt is driven to rotate to grind the fixed photovoltaic film sample. The device can open the placement groove by rotating the baffle, and the clamping plate has a positioning function, making the placement and removal of the photovoltaic film sample extremely convenient, avoiding manual adjustment of the position of the photovoltaic film sample, resulting in inaccurate positioning caused by human factors, causing the photovoltaic film sample to be misplaced, and resulting in poor effect of the photovoltaic film sample.

[0017] 2. By providing a conveyor belt and an air inlet, when the photovoltaic film sample inside the clamping plate is ground, the piston plate inside the baffle is driven to move, so that negative pressure is generated inside the baffle, and the negative pressure adsorbs the photovoltaic film sample through the air inlet. Then the photovoltaic film sample follows the rotation of the baffle and slides out of the placement groove. When it slides out a distance and one end of the photovoltaic film sample is directly above the conveyor belt, the piston plate is driven to reset, so that gas is sprayed out of the air inlet, so that the photovoltaic film sample falls onto the conveyor belt, and the automatic unloading operation can be completed by the rotation of the conveyor belt. The device can automatically unload the ground photovoltaic film samples without the need for manual picking up by the staff, which not only reduces the labor intensity of the operators, but also improves the efficiency of the grinding process.

[0018] 3. By providing a cleaning section, when the baffle is reset, the baffle drives the magnetic rod to move in the cleaning section, so that the piston plate moves inside the baffle, and the air inlet continues to discharge air flow, thereby cleaning the impurities inside the air inlet, thereby preventing impurities generated by grinding in the external environment from adhering to the air inlet when the baffle is reset, causing impurities to block the air inlet, making it difficult to adsorb the photovoltaic film samples and automatically discharge them.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a POE encapsulation photovoltaic film cross-section grinding tool. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 10 As shown, the present invention provides: a POE encapsulated photovoltaic film cross-section grinding tool, comprising a workbench 1, a grinding belt 11 is rotatably provided on the workbench 1, a clamping plate 2 is provided on the grinding belt 11, a positioning rod 21 and a pull rod 22 are fixedly connected to the clamping plate 2, the positioning rod 21 and the pull rod 22 are both slidably connected to the inside of a support frame 13, the support frame 13 is fixedly connected to the upper surface of the workbench 1, a clamping spring 23 is fixedly connected between the clamping plate 2 and the support frame 13, a placement groove 24 is provided inside the clamping plate 2, and an adjustment mechanism is provided on one side of the clamping plate 2, the adjustment mechanism includes a baffle 3 rotatably connected to one side of the clamping plate 2; when placing a photovoltaic film sample, the baffle 3 is driven to rotate so that one side of the placement groove 24 is opened, at this time, the clamping plate 2 can position and place the photovoltaic film sample, and when grinding the photovoltaic film sample, the baffle 3 is driven to block one side of the placement plate, and the clamping plate 2 presses down the photovoltaic film sample and performs a grinding operation through the grinding belt 11.

[0023] Before the existing POE encapsulated photovoltaic film cross-section grinding device performs the grinding operation on the photovoltaic film sample, it is necessary to manually place the photovoltaic film sample directly under the clamping plate 2, and then the clamping plate 2 falls to press down and fix the photovoltaic film sample. After the fixation is completed, the grinding device is turned on to grind the photovoltaic film sample inside the clamping plate 2; When the above-mentioned existing grinding device is used, the user manually positions the photovoltaic film sample to the bottom of the clamping plate 2. When the operator manually places the photovoltaic film sample, due to limitations of visual judgment, hand movements and other factors, the positioning of the photovoltaic film sample is inaccurate, resulting in a slight deviation in the placement position, causing the photovoltaic film sample to shift or tilt during the grinding process, resulting in reduced grinding efficiency and poor grinding effect. In order to solve the above problems, the working principle of the present invention is as follows: first, the POE encapsulated photovoltaic film is cut into photovoltaic film samples of certain sizes. After the cutting is completed, the pull rod 22 is pulled, and the pull rod 22 drives the clamping plate 2 to move upward, and the clamping plate 2 drives the positioning rod 21 to slide inside the support frame 13 and squeeze the clamping spring 23. After the clamping plate 2 moves to a certain height, the baffle 3 is driven to rotate, and the baffle 3 rotates to open the placement groove 24. At this time, the clamping plate 2 is relative to a positioning frame, and the user can position the photovoltaic film sample through the placement groove 24 so that the inner upper surface of the placement groove 24 is in contact with the upper surface of the photovoltaic film sample, and the lower surface of the photovoltaic film sample and The surface of the grinding belt 11 is fitted. When the photovoltaic film sample is positioned and placed, the baffle 3 is driven to reset. The baffle 3 blocks the placement groove 24 and limits the photovoltaic film sample so that the photovoltaic film sample is inside the placement groove 24. Then the pull rod 22 is released to allow the clamping spring 23 to press down the photovoltaic film sample. When the photovoltaic film sample is fixed, the grinding belt 11 is driven to rotate. The grinding belt 11 rotates and contacts the cross-section of the photovoltaic film sample, and the cross-section of the photovoltaic film sample is ground. The photovoltaic film sample is ground to change its volume. At this time, the fixing spring 352 drives the clamping plate 2 to descend, and the clamping plate 2 keeps the photovoltaic film sample pressed down and fixed.

[0024] The device can open the placement slot 24 by rotating the baffle plate 3, so that the clamping plate 2 has a positioning function, making the placement and removal of the photovoltaic film sample extremely convenient, avoiding manual adjustment of the position of the photovoltaic film sample, leading to inaccurate positioning caused by human factors, causing the photovoltaic film sample to be misplaced, and resulting in poor effect of the photovoltaic film sample.

[0025] like Figure 3 and Figure 5 As shown, the clamping plate 2 is fixedly connected with a slide bar 252, and the slide bar 252 is slidably connected with a rack 251. Both sides of the baffle 3 are fixedly connected with a rotating rod 31, and the rotating rod 31 is fixedly connected with a gear 32. The gear 32 and the rack 251 are meshed with each other.

[0026] Specifically, when it is necessary to drive the baffle 3 to rotate, the rack 251 can be driven to slide on the slide rod 252, and the rack 251 and the gear 32 are engaged, so that the gear 32 rotates, and the gear 32 then drives the rotating rod 31 fixed inside it to rotate synchronously, and the rotating rod 31 then drives the baffle 3 to rotate synchronously. The baffle 3 rotates to open the placement slot 24. The baffle 3 is driven to rotate by the engagement of the rack 251 and the gear 32, and the baffle 3 can be stably driven to rotate a specified angle.

[0027] like Figure 3 and Figure 5As shown, an electric cylinder 25 is fixedly connected to the clamping plate 2 , and the telescopic end of the electric cylinder 25 is fixedly connected to the inside of the rack 251 .

[0028] Specifically, when it is necessary to drive the rack 251 to slide on the clamping plate 2, the electric cylinder 25 can be opened, and the telescopic end of the electric cylinder 25 drives the rack 251 to move, and the rack 251 can mesh with the gear 32 and drive the baffle 3 to rotate. A button is provided on the pull rod 22. When the user pulls the pull rod 22, the button can be pressed. The button and the electric cylinder 25 are electrically connected, so that the electric cylinder 25 is opened and works.

[0029] like Figure 6 As shown, the interior of the baffle 3 is slidably connected to a piston plate 35, the outer wall of the baffle 3 is provided with a plurality of air inlet holes 33, the interior of the baffle 3 is fixedly connected to a fixing plate 34, and a fixing spring 352 is fixedly connected between the piston plate 35 and the inner wall of the fixing plate 34.

[0030] like Figure 1 and Figure 2 As shown, a conveyor belt 12 is arranged on the workbench 1, and the conveyor belt 12 is arranged at an angle.

[0031] like Figure 7 As shown, a fixing rod 36 is fixedly connected to one side of the clamping plate 2, and the fixing rod 36 is located on the inner side of the rotating rod 31. An electromagnet 37 is fixedly connected inside the fixing rod 36, and a magnetic rod 351 is fixedly connected to the upper surface of the piston plate 35. After being energized, the electromagnet 37 can adsorb the magnetic rod 351, so that the magnetic rod 351 drives the piston plate 35 to slide inside the baffle 3.

[0032] like Figure 7 and Fig. 9 As shown, a first protrusion 39 is fixedly connected to the fixing rod 36 , and a second protrusion 391 is fixedly connected to one side of the first protrusion 39 .

[0033] Specifically, when the photovoltaic film sample is ground, the user needs to hold the pull rod 22 with one hand, then drive the baffle 3 to open, manually remove the ground photovoltaic film sample inside the placement groove 24, and then replace the photovoltaic film sample to be ground after removing it, and finally drive the baffle 3 to seal the placement groove 24; The above operation steps are cumbersome and require users to consume a lot of time and energy, resulting in a decrease in overall production efficiency; In order to avoid the above problems, the working principle of the present invention is as follows: before driving the baffle 3 to rotate, the electromagnet 37 can be turned on to work, the electromagnet 37 generates a magnetic force to adsorb the magnetic rod 351, and the magnetic rod 351 drives the piston plate 35 to slide inside the baffle 3, and the piston plate 35 slides to the side of the electromagnet 37, and the piston plate 35 moves and squeezes the fixed spring 352, and the piston plate 35 slides, so that a negative pressure airflow is generated inside the piston plate 35, and the negative pressure airflow enters through the air inlet 33. At this time, the negative pressure airflow drives the photovoltaic film sample to be adsorbed on the baffle 3, and then The rear driving baffle 3 rotates, and the baffle 3 drives the adsorbed photovoltaic film sample to rotate synchronously. At the same time, the baffle 3 drives the magnetic rod 351 to rotate around the fixed rod 36. When the magnetic rod 351 rotates to the first protrusion 39, the first protrusion 39 squeezes the magnetic rod 351, so that the magnetic rod 351 drives the piston plate 35 to move in the direction of the air inlet 33. At this time, the piston plate 35 blows out air flow and releases the adsorption of the photovoltaic film sample, so that one end of the photovoltaic film sample falls on the inclined conveyor belt 12. The conveyor belt 12 rotates and drives the photovoltaic film sample to automatically unload. The device can automatically unload the ground photovoltaic film samples without the need for manual picking up by staff, which not only reduces the labor intensity of operators but also improves the efficiency of the grinding process.

[0034] like Figure 8-Figure 10 As shown, a limiting plate 38 is fixedly connected to the fixed rod 36, and a limiting groove 381 is provided inside the limiting plate 38. A roller 353 is slidably connected inside the limiting groove 381. The roller 353 and the magnetic rod 351 are rotatably connected via a shaping rod. The limiting groove 381 includes a suction section 3811, a discharge section 3812 is provided on one side of the suction section 3811, a reset section 3813 is provided on one side of the discharge section 3812, a cleaning section 3814 is provided on one side of the reset section 3813, the cleaning section 3814 is communicated with one side of the suction section 3811, and the depth of the cleaning section 3814 is less than the depth of the suction section 3811, and the depth of the reset section 3813 is less than the depth of the discharge section 3812.

[0035] Specifically, when the baffle 3 is reset, the electromagnet 37 remains in the open state, the magnetic rod 351 is reset and slides down from the first protrusion 39, and one end of the magnetic rod 351 is adsorbed by the electromagnet 37, so that the piston plate 35 moves toward the electromagnet 37, thereby generating a negative pressure airflow, which may adsorb the photovoltaic film sample debris generated by grinding and diffused in the environment, and the impurities are accumulated at the air inlet 33, which may cause the air inlet 33 to be blocked. When the electromagnet 37 is in the closed state and the baffle 3 is reset and rotated, the impurities generated by grinding and diffused in the environment contact and adhere to the air inlet 33, causing the problem of blockage. In order to solve the above problems, the working principle of the present invention is as follows: in the initial state, the electromagnet 37 is turned on, and the magnetic rod 351 is adsorbed by the electromagnet 37, so that the magnetic rod 351 drives the roller 353 to slide in the limit groove 381, and the magnetic rod 351 drives the roller 353 to slide in the suction section 3811, and at this time, the baffle 3 adsorbs the photovoltaic film sample; Then the magnetic rod 351 rotates along with the baffle 3, and the magnetic rod 351 drives the roller 353 to slide from the suction section 3811 to the discharge section 3812. At this time, the magnetic rod 351 is squeezed by the first protrusion 39, and the baffle 3 releases the adsorption of the photovoltaic film sample, so that the photovoltaic film sample falls onto the conveyor belt 12 for automatic unloading operation. The magnetic rod 351 drives the pulley to continue rotating, and the pulley slides from the discharge section 3812 to the reset section 3813. At this time, the magnetic rod 351 slides from the first protrusion 39 to the second protrusion 391, and the piston plate 35 is in the initial position. Since the depth of the reset section 3813 is less than the depth of the discharge section 3812, the baffle 3 then drives the magnetic rod 351 to reset, so that the roller 353 slides in the reset section 3813. When the roller 353 slides from the reset section 3813 and the cleaning section 3814, the piston plate 35 moves to generate an adsorption force, and then the roller 353 enters the cleaning section 3814. When the roller 353 slides in the cleaning section 3814, the piston plate 35 gradually moves in the direction of the air inlet hole 33 and blows out air through the air inlet hole 33 to clean the debris attached to the surface of the air inlet hole 33. Then the roller 353 passes through the cleaning section 3814 and enters the suction section 3811. At this time, the baffle 3 and one side of the clamping plate 2 are in contact, and then the magnetic rod 351 is continued to be adsorbed by the electromagnet 37. Because the depth of the cleaning section 3814 is less than the depth of the suction section 3811, the roller 353 slides in the suction section 3811. At this time, the baffle 3 and one side of the clamping plate 2 are in contact and will not be affected by the debris in the external environment. After the fixing is completed, the electromagnet 37 is turned off, and the magnetic rod 351 is driven to drive the piston plate 35 to reset.

[0036] The device cleans the impurities at the air inlet 33 to prevent the impurities generated by grinding in the external environment from adhering to the air inlet 33 when the baffle 3 is reset, causing the impurities to block the air inlet 33, making it difficult to adsorb the photovoltaic film sample and automatically discharge it.

[0037] Working principle: First, cut the POE encapsulated photovoltaic film into photovoltaic film samples of certain sizes. After the cutting is completed, pull the pull rod 22, and the pull rod 22 drives the clamping plate 2 to move upward, and the clamping plate 2 drives the positioning rod 21 to slide inside the support frame 13 and squeeze the clamping spring 23. After the clamping plate 2 moves to a certain height, the electric cylinder 25 can be opened, and the telescopic end of the electric cylinder 25 drives the rack 251 to move, and the rack 251 slides on the slide rod 252, and the rack 251 and the gear 32 are meshed, so that the gear 32 rotates, and the gear 32 then drives the rotating rod 31 fixed inside it to rotate synchronously, and the rotating rod 31 then drives the baffle 3 to rotate synchronously, and the baffle 3 rotates to open the placement slot 24. At this time, the clamping plate 2 is relative to a positioning frame, and the user can position the photovoltaic film sample through the placement slot 24, so that the inner upper surface of the placement slot 24 fits with the upper surface of the photovoltaic film sample, and the lower surface of the photovoltaic film sample fits with the surface of the grinding belt 11; When the photovoltaic film sample is positioned and placed, the baffle 3 is driven to reset, the baffle 3 blocks the placement groove 24, and limits the photovoltaic film sample so that the photovoltaic film sample is inside the placement groove 24, and then the pull rod 22 is loosened to allow the clamping spring 23 to press down the photovoltaic film sample. When the photovoltaic film sample is fixed, the grinding belt 11 is driven to rotate, the grinding belt 11 rotates and contacts the cross-section of the photovoltaic film sample, and the cross-section of the photovoltaic film sample is ground. The photovoltaic film sample is ground to change its volume. At this time, the fixing spring 352 drives the clamping plate 2 to descend, and the clamping plate 2 keeps the photovoltaic film sample pressed down and fixed.

[0038] When the ground photovoltaic film sample needs to be replaced, the electromagnet 37 can be turned on to work and the pull rod 22 can be used to make the clamping plate 2 disengage from the downward pressure on the photovoltaic film sample. The electromagnet 37 generates a magnetic force to adsorb the magnetic rod 351, and the magnetic rod 351 drives the piston plate 35 to slide inside the baffle 3. The piston plate 35 slides to the side of the electromagnet 37. The piston plate 35 moves and squeezes the fixed spring 352. The piston plate 35 slides, so that a negative pressure airflow is generated inside the piston plate 35. The negative pressure airflow enters through the air inlet 33. At this time, the negative pressure airflow drives the photovoltaic film sample to be adsorbed. Attached to the baffle 3, the baffle 3 is then driven to rotate, and the baffle 3 drives the adsorbed photovoltaic film sample to rotate synchronously. At the same time, the baffle 3 drives the magnetic rod 351 to rotate around the fixed rod 36. When the magnetic rod 351 rotates to the first protrusion 39, the first protrusion 39 squeezes the magnetic rod 351, so that the magnetic rod 351 drives the piston plate 35 to move in the direction of the air inlet 33. At this time, the piston plate 35 blows out air flow and releases the adsorption of the photovoltaic film sample, so that one end of the photovoltaic film sample falls on the inclined conveyor belt 12, and the conveyor belt 12 rotates and drives the photovoltaic film sample to automatically unload the material; In the initial state, the electromagnet 37 is turned on, and the magnetic rod 351 is adsorbed by the electromagnet 37, so that the magnetic rod 351 drives the roller 353 to slide in the limit groove 381, and the magnetic rod 351 drives the roller 353 to slide in the suction section 3811, and the baffle 3 adsorbs the photovoltaic film sample; Then the magnetic rod 351 rotates along with the baffle 3, and the magnetic rod 351 drives the roller 353 to slide from the suction section 3811 to the discharge section 3812. At this time, the magnetic rod 351 is squeezed by the first protrusion 39, and the baffle 3 releases the adsorption of the photovoltaic film sample, so that the photovoltaic film sample falls onto the conveyor belt 12 for automatic unloading operation. The magnetic rod 351 drives the pulley to continue rotating, and the pulley slides from the discharge section 3812 to the reset section 3813. At this time, the magnetic rod 351 slides from the first protrusion 39 to the second protrusion 391, and the piston plate 35 is in the initial position. Since the depth of the reset section 3813 is less than the depth of the discharge section 3812, the baffle 3 then drives the magnetic rod 351 to reset, so that the roller 353 slides in the reset section 3813. When the roller 353 slides from the reset section 3813 and the cleaning section 3814, the piston plate 35 moves to generate an adsorption force, and then the roller 353 enters the cleaning section 3814. When the roller 353 slides in the cleaning section 3814, the piston plate 35 gradually moves in the direction of the air inlet 33 and blows out air through the air inlet 33 to clean the debris attached to the surface of the air inlet 33. Then the roller 353 enters the suction section 3811 through the cleaning section 3814. At this time, the baffle 3 and one side of the clamping plate 2 are in contact, and then the magnetic rod 351 is continued to be adsorbed by the electromagnet 37. Because the depth of the cleaning section 3814 is less than the depth of the suction section 3811, the roller 353 slides in the suction section 3811. At this time, the baffle 3 and one side of the clamping plate 2 are in contact and will not be affected by the debris in the external environment. After the fixing is completed, the electromagnet 37 is turned off, and the magnetic rod 351 is driven to drive the piston plate 35 to reset, and then the replaced photovoltaic film sample can be ground.

[0039] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a POE encapsulation photovoltaic film cross-section grinding tool and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
