Description

Technical Field

[0001] This invention relates to the field of solar panel processing, and more particularly to an automatic rotating edge trimming device and edge trimming method for solar panels. Background Technology

[0002] As is well known, the edge quality of solar panels, as the core component of photovoltaic modules, directly affects the yield rate of subsequent encapsulation processes and the long-term reliability of the modules. After the solar panels are laminated, defects such as waste encapsulant film, waste backsheet edges, and burrs often exist at the edges, which need to be treated by edge trimming (or chamfering) to eliminate stress concentration points and improve mechanical strength and electrical insulation performance.

[0003] Most existing edge trimming equipment for solar panels operates in a single-station or dual-station sequential processing mode. In this mode, the solar panel needs to go through multiple independent and intermittent steps, such as loading, positioning, performing edge trimming in one direction, cleaning, turning, repositioning, performing edge trimming in another direction, and finally unloading. The cumulative transition and waiting time between each process severely restricts the overall production cycle, making it difficult for the theoretical capacity of the equipment to match the high-speed rhythm of the preceding sorting, cutting, welding, stacking, and laminating processes. This becomes a bottleneck in improving the overall production efficiency. Furthermore, since the edge trimming process often generates debris, there is currently a lack of efficient and synchronous cleaning structures for this debris. Therefore, during continuous edge trimming, the time is affected by the debris generated by the preceding edge trimming, leading to a decrease in the quality of subsequent edge trimming. Finally, the edge trimming blade, as the core consumable component of the edge trimming mechanism, needs to be replaced frequently to ensure processing efficiency. However, in traditional designs, the blade is usually fastened with multiple micro screws or embedded in complex clips. The replacement process requires special tools, which is cumbersome and time-consuming. Summary of the Invention

[0004] (a) Purpose of the invention In view of this, the purpose of this invention is to propose an automatic rotating edge trimming device and edge trimming method for solar panels. The device adopts a four-station continuous processing mode, which greatly improves the processing efficiency of solar panels. Furthermore, by designing the structure of the edge trimming component, the device can simultaneously collect the debris generated during edge trimming of the solar panels, ensuring a smoother continuous edge trimming process.

[0005] (II) Technical Solution To achieve the above technical objectives, the present invention provides an automatic rotating edge trimming device and edge trimming method for solar panels, comprising a platform, with four workstations arranged sequentially above the platform according to the moving processing direction of the solar panels: a loading workstation, a long edge trimming workstation, a short edge trimming workstation, and a unloading workstation. A rotating platform capable of lifting and rotating is installed at the center of the upper part of the platform, and brackets corresponding to the four workstations are installed on the outer side of the rotating platform. Each bracket is equipped with a suction cup attachment capable of adsorbing solar panels, which allows the solar panels to be adsorbed and moved between the four workstations. Above the platform, at the loading station and the unloading station, feeding conveyor belts and unloading conveyor belts are respectively installed for loading and unloading. Above the platform, at the long side trimming station and the short side trimming station, trimming mechanisms capable of trimming the long and short sides of the solar panels are installed. The trimming assembly includes a material placement mechanism and a trimming mechanism. The trimming mechanism is located on both sides of the material placement mechanism. The material placement mechanism can fix the solar panels and drive the solar panels to move, so that the trimming mechanism can perform trimming operations on the solar panels on the material placement mechanism.

[0006] As a further description of the above technical solution: the material placement mechanism includes a frame, a slide table, and a material platform with suction cups. The frame is fixedly installed above the platform body and has a U-shaped structure. A slide rod is installed between the two vertical ends of the frame, and the slide table is slidably installed on the slide rod. The material platform with suction cups is fixedly installed on the top of the slide table. The frame is also provided with a first motion control unit for driving the slide table to slide along the length direction of the slide rod. Based on this, the material platform with suction cups can adsorb and fix the solar panel, and under the drive of the first motion control unit, the slide table slides along the length direction of the slide rod, thus realizing the fixing and movement control of the solar panel.

[0007] As a further description of the above technical solution: the edge-trimming mechanism includes a mounting frame and an edge-trimming unit. The mounting frame is fixedly installed above the platform. An installation cavity is formed on the upper surface of the mounting frame along the width direction. The edge-trimming unit is disposed above the mounting frame. A slider is mounted on the bottom center position of the edge-trimming unit via a connecting column. The slider is slidably assembled in the installation cavity. A second movement control unit for driving the slider to slide in the installation cavity is installed on the mounting frame. Based on this, the second movement control unit can drive the slider to slide in the installation cavity, thereby adjusting the position of the edge-trimming unit located above the slider. This allows the actual position of the edge-trimming mechanism in the device to be adjusted as needed, improving the applicability of the device.

[0008] As a further description of the above technical solution: the edge trimming unit has a blade slot below one end near the material placement mechanism, and a blade is detachably assembled in the blade slot. The edge trimming unit is also equipped with a blade fixing unit for locking or unlocking the blade. In addition, the blade's cutting edge direction corresponds to the moving direction of the solar panel. Therefore, when the solar panel moves, the blade's cutting edge can trim the edge of the solar panel.

[0009] As a further description of the above technical solution: the surface of the blade is provided with at least two positioning holes. The blade fixing unit includes a spring pin, a control rod, and a wedge. The spring pin is disposed within the edge-trimming unit and corresponds to the number and position of the positioning holes. The spring pin can move and engage with the positioning holes along the length direction perpendicular to the blade, thereby locking the blade. A wedge-shaped opening is provided on the spring pin along the length direction of the blade. The control rod is inserted into the edge-trimming unit and can slide within the edge-trimming unit along the length direction of the blade. The wedge corresponds to the number and position of the spring pin and is fixedly installed on the control rod. The wedge is inserted into the wedge-shaped opening. Based on this, when the control rod is pressed, the wedge on the control rod moves within the wedge-shaped opening. Under the action of the wedge structure, the spring pin retracts. When the front end of the spring pin exits the positioning hole, the blade can be directly disassembled, making the operation convenient and quick.

[0010] As a further description of the above technical solution: A first spring is installed at one end of the spring pin, which can provide a pushing force to the spring pin, giving it a tendency to move in the direction of the blade. A baffle is installed on the control rod, and a second spring is sleeved on the control rod at the baffle. The second spring can provide an outward pushing force to the control rod through the baffle, giving it a tendency to move outward. Based on this, after the blade is installed in place, the control rod can be released directly. Under the elastic force of the second spring, the control rod automatically returns to its initial position. Therefore, the wedge on the control rod loses its squeezing of the spring pin, and the spring pin automatically pops out under the elastic force of the first spring, so that its front end is locked into the positioning hole on the blade, thus realizing automatic locking of the blade. The operation is convenient and quick.

[0011] As a further description of the above technical solution: A cavity is provided below the trimming unit on the side of the blade, and a pre-collection box is inserted into the cavity. A cover is provided on the top of the pre-collection box, and a primary air filter plate is installed on the cover. A material collection groove is provided at the bottom of the trimming unit near the blade. An air inlet is provided at the bottom of the pre-collection box corresponding to the material collection groove, and the material collection groove is connected to the air inlet. An air pipe is provided inside the trimming unit, and one end of the air pipe is connected to the primary air filter plate. Therefore, when the equipment is performing trimming operations, the external negative pressure suction duct can provide negative pressure to the pre-collection box through the air pipe, allowing the debris generated during trimming to enter the pre-collection box through the material collection groove and the air inlet, thus achieving debris collection.

[0012] As a further description of the above technical solution: A lifting platform is provided above the platform body, and a hydraulic jack is provided between the lifting platform and the platform body. The hydraulic jack can push the lifting platform to move in the vertical direction. The rotating platform is rotatably mounted outside the hydraulic jack through bearings. Based on this, the rotating platform can rotate outside the hydraulic jack, thereby changing the working position of each bracket. In order to avoid interference from the edge-cutting component when the bracket and suction cup accessories drive the solar panel to rotate and adjust the working position, the hydraulic jack can push the lifting platform to rise, so that the bracket, suction cup accessories and solar panel rise synchronously, thereby achieving the effect of obstacle avoidance.

[0013] As a further description of the above technical solution: A rotating ring is fixedly installed above the rotating table, and a driven gear ring is installed on the inner side of the rotating ring. A workstation switching motor is fixedly installed on the top of the lifting platform through a fixing frame. A drive gear is installed on the output shaft of the workstation switching motor. The drive gear meshes with the driven gear ring. Based on this, when the workstation switching motor runs, it can drive the drive gear to rotate. Since the drive gear meshes with the driven gear ring, the driven gear ring drives the rotating table to rotate through the rotating ring, thereby realizing the switching of workstations.

[0014] This application also discloses a trimming method for an automatic rotating trimming device for solar panels, the specific steps of which are as follows: S1: The solar panels are transported to the loading station via the feeding conveyor belt. At the loading station, the suction cup attachment under the bracket will adsorb the solar panels. S2: The station switching motor runs, controlling the rotary table to rotate 90 degrees, so that the solar panel reaches the long side trimming station. The hydraulic jack drives the rotary table to move down until the solar panel is located above the suction cup material platform and is attracted and fixed. The hydraulic jack drives the rotary table to move up to avoid affecting the trimming. At this time, the suction cup material platform slides along the length direction of the slide rod under the drive of the first mobile control unit. During this process, the blades in the trimming units located on both sides of the suction cup material platform trim the long side of the solar panel until the trimming is completed. The first mobile control unit controls the suction cup material platform to reset, the hydraulic jack drives the rotary table to move down, and the suction cup attachment under the bracket attracts the solar panel on the long side trimming station. S3: The station switching motor runs, controlling the rotary table to rotate 90 degrees, so that the solar panel reaches the short side trimming station. Similarly, the short side of the solar panel is trimmed in the short side trimming station. S4: After the short side is trimmed, the suction cup attachment will adsorb and transfer the trimmed solar panel onto the discharge conveyor belt, and then convey it out through the discharge conveyor belt.

[0015] In the above technical solution, the automatic rotary edge trimming device and edge trimming method for solar panels provided by the present invention adopt a four-station continuous processing mode, namely feeding - long edge trimming - short edge trimming - discharge. This can greatly improve the processing efficiency of solar panels. Furthermore, by designing the structure of the edge trimming component, the device can simultaneously collect the debris generated during edge trimming, ensuring a smoother continuous edge trimming process. Moreover, by designing the edge trimming mechanism in the edge trimming component, the blades on the edge trimming mechanism are easy to install and remove, and it is convenient to replace the blades by air intake, further ensuring the efficiency of edge trimming in solar panel processing.

[0019] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0020] like Figure 1 - Figure 10 As shown: This embodiment provides a technical solution: an automatic rotating edge trimming device for solar panels and its edge trimming method, including a platform 1. Four workstations are arranged on the top of the platform 1 in sequence according to the moving processing direction of the solar panels, namely a feeding workstation, a long edge trimming workstation, a short edge trimming workstation, and a discharging workstation. A rotating platform 6 capable of lifting and rotating is installed at the center of the top of the platform 1. Supports 61 corresponding to the four workstations are installed on the outside of the rotating platform 6. A suction cup attachment 62 capable of adsorbing solar panels is installed below each support 61. The solar panels can be adsorbed and moved between the four workstations through the suction cup attachment 62. Above the platform 1, at the loading station and the unloading station, there are feeding conveyor belts 2 and unloading conveyor belts 5 for loading and unloading, respectively. Above the platform 1, at the long side trimming station and the short side trimming station, there are trimming mechanisms 31 that can trim the long and short sides of the solar panel. The trimming assembly 3 includes a material placement mechanism 30 and a trimming mechanism 31. The trimming mechanism 31 is located on both sides of the material placement mechanism 30. The material placement mechanism 30 can fix the solar panel and drive the solar panel to move, so that the trimming mechanism 31 can perform trimming operation on the solar panel on the material placement mechanism 30. Working principle: First, the solar panel is conveyed to the loading station by the feeding conveyor belt 2. In the loading station, it is attracted by the suction cup attachment 62 under the bracket 61. Then, the rotary table 6 rotates 90 degrees, so that the solar panel reaches the long side trimming station. At this time, the solar panel is attracted by the feeding mechanism 30 and moves. During the movement, the long side of the solar panel is cut by the trimming mechanism 31. After the long side trimming is completed, the solar panel is attracted by the suction cup attachment 62 under the bracket 61 again and rotates 90 degrees. The solar panel enters the short side trimming station. Similarly, after the short side trimming is performed, the solar panel is attracted and transferred to the unloading station. The cycle is repeated to complete the continuous trimming operation of the solar panel. Specifically, such as Figure 1 - Figure 3As shown, in order to achieve the fixing and movement control of the solar panel by the material placement mechanism 30, in this embodiment, the material placement mechanism 30 includes a frame 300, a slide table 301, and a material platform 303 with suction cups. The frame 300 is fixedly installed above the platform 1. The frame 300 adopts a U-shaped structure. A slide rod 304 is installed between the two vertical ends of the frame 300. The slide table 301 is slidably installed on the slide rod 304. The material platform 303 with suction cups is fixedly installed on the top of the slide table 301. The frame 300 is also provided with a first movement control unit 302 for driving the slide table 301 to slide along the length direction of the slide rod 304. Based on this, the material platform 303 with suction cups can adsorb and fix the solar panel, and under the drive of the first movement control unit 302, the slide table 301 slides along the length direction of the slide rod 304, thus realizing the fixing and movement control of the solar panel.

[0021] Specifically, such as Figure 4 As shown, in order to ensure that the edge trimming mechanism 31 can adjust the trimming position according to the actual length and width of the solar panel before trimming the edge, in this embodiment, the edge trimming mechanism 31 includes a mounting frame 310 and an edge trimming unit 315. The mounting frame 310 is fixedly mounted above the platform 1. The upper surface of the mounting frame 310 has a mounting cavity 313 along the width direction. The edge trimming unit 315 is disposed above the mounting frame 310. A slider 312 is mounted at the bottom center of the edge trimming unit 315 through a connecting column 314. The slider 312 is slidably assembled in the mounting cavity 313. A second movement control unit 311 for driving the slider 312 to slide in the mounting cavity 313 is mounted on the mounting frame 310. Based on this, the second movement control unit 311 can drive the slider 312 to slide in the mounting cavity 313, thereby adjusting the position of the edge trimming unit 315 located above the slider 312. This allows the actual position of the edge trimming mechanism 31 in the device to be adjusted as needed, improving the applicability of the device. It should also be noted that both the first motion control unit 302 and the second motion control unit 311 use lead screw units. The lead screw unit includes a lead screw, a lead screw nut, and a motor. The motor is connected to one end of the lead screw and can drive the lead screw to rotate. The lead screw nut is sleeved on the lead screw, and the lead screw is embedded in the passive sliding structure. Therefore, when the lead screw rotates, it can drive the passive sliding structure to slide along the length of the lead screw. The aforementioned passive sliding structure is the slide table 301 and the slider 312.

[0022] Specifically, such as Figure 5 - Figure 6As shown, in order to achieve edge trimming, in this embodiment, a blade slot 3150 is provided below one end of the edge trimming unit 315 near the material placement mechanism 30. A blade 318 is detachably mounted in the blade slot 3150, and a blade fixing unit 319 for locking or unlocking the blade 318 is installed in the edge trimming unit 315. In addition, the cutting edge direction of the blade 318 corresponds to the moving direction of the solar panel. Therefore, when the solar panel moves, the cutting edge of the blade 318 can trim the edge of the solar panel.

[0023] Specifically, such as Figure 5 - Figure 8 As shown, in order to achieve detachable installation of the blade 318 and facilitate replacement of the blade 318, in this embodiment, at least two positioning holes 3180 are provided on the surface of the blade 318. The blade fixing unit 319 includes a spring pin 3190, a control rod 3193, and a wedge 3194. The spring pin 3190 is disposed in the beveling unit 315 and corresponds to the number and position of the positioning holes 3180. The spring pin 3190 can move along the length direction perpendicular to the blade 318 and engage with the positioning hole 3180 to lock the blade 318. A wedge-shaped opening 3191 is provided on the spring pin 3190 along the length direction of the blade 318. The control lever 3193 is inserted into the trimming unit 315 and can slide along the length of the blade 318 within the trimming unit 315. The wedge-shaped piece 3194 corresponds to the number and position of the spring pin 3190 and is fixedly installed on the control lever 3193. The wedge-shaped piece 3194 is inserted into the wedge-shaped opening 3191. Based on this, when the control lever 3193 is pressed, the wedge-shaped piece 3194 on the control lever 3193 moves within the wedge-shaped opening 3191. Under the action of the wedge structure, the spring pin 3190 retracts. When the front end of the spring pin 3190 exits the positioning hole 3180, the blade 318 can be directly disassembled, making the operation convenient and quick.

[0024] Specifically, such as Figure 5 - Figure 8As shown, to ensure stability when fixing the blade 318 and to allow the control lever 3193 to automatically reset after replacing the blade 318, in this embodiment, a first spring 3192 is installed at one end of the spring pin 3190. The first spring 3192 can provide a pushing force to the spring pin 3190, giving it a tendency to move towards the blade 318. A baffle 3196 is installed on the control lever 3193, and a second spring 3195 is sleeved on the control lever 3193 at the baffle 3196. The second spring 3195 can push the control lever 3193 through the baffle 3196. The outward thrust is provided, giving it an outward tendency to move. Based on this, after the blade 318 is installed in place, the control lever 3193 is released directly. The control lever 3193 automatically returns to its initial position under the elastic force of the second spring 3195. Therefore, the wedge 3194 on the control lever 3193 loses its pressure on the spring pin 3190. The spring pin 3190 automatically pops out under the elastic force of the first spring 3192, so that its front end is locked into the positioning hole 3180 on the blade 318, thus realizing the automatic locking of the blade 318. The operation is convenient and quick.

[0025] Specifically, such as Figure 5 - Figure 6 As shown, to ensure the collection of debris and facilitate smooth subsequent edge trimming, in this embodiment, a cavity 3152 is provided below the edge trimming unit 315 on the side of the blade 318. A front collection box 317 is inserted into the cavity 3152. A cover 3170 is provided on the top of the front collection box 317, and a primary air filter plate 3171 is installed on the cover 3170. A scrap collection groove 3151 is provided at the bottom of the edge trimming unit 315 near the blade 318. The bottom of the front collection box 317 corresponds to the position of the scrap collection groove 3151. An air inlet 3172 is provided, and the material collection trough 3151 is connected to the air inlet 3172. An air passage pipe 3160 is provided inside the trimming unit 315. One end of the air passage pipe 3160 is connected to the position of the primary air passage filter plate 3171. Based on this, when the equipment is performing trimming operation, the external negative pressure suction air duct can provide negative pressure to the front collection box 317 through the air passage pipe 3160, so that the debris generated by trimming can enter the front collection box 317 through the material collection trough 3151 and the air inlet 3172 to collect the debris.

[0026] Specifically, such as Figure 5 , Figure 9 - Figure 10As shown, in order to perform simultaneous dust removal while collecting debris, the edge trimming unit 315 is also connected to a rear collection cylinder 316 in the air passage pipe 3160. The rear collection cylinder 316 includes an outer cylinder 3161 with a tubular structure and an inner cylinder 3162 assembled in the outer cylinder 3161. The outer cylinder 3161 has an insertion slot 3163 at the top, and the inner cylinder 3162 is detachably assembled in the insertion slot 3163 from top to bottom. The air outlet end of the inner cylinder 3162 is provided with a secondary air passage filter plate 3164. Therefore, the device can remove dust from the processing environment while collecting debris.

[0027] Specifically, such as Figure 1 - Figure 2 As shown, to avoid interference from the edge-trimming component 3 when the equipment changes work positions, in this embodiment, a lifting platform 63 is provided above the platform 1, and a hydraulic jack 60 is provided between the lifting platform 63 and the platform 1. The hydraulic jack 60 can push the lifting platform 63 to move vertically. The rotating platform 6 is rotatably mounted outside the hydraulic jack 60 through bearings. Based on this, the rotating platform 6 can rotate outside the hydraulic jack 60, thereby changing the work position of each bracket 61. In order to avoid interference from the edge-trimming component 3 when the bracket 61 and the suction cup accessory 62 drive the solar panel to rotate and adjust the work position, the hydraulic jack 60 can push the lifting platform 63 to rise, so that the bracket 61, the suction cup accessory 62 and the solar panel rise synchronously, thereby achieving the effect of obstacle avoidance.

[0028] Specifically, such as Figure 1 - Figure 2 As shown, in order to achieve the switching of workstations, in this embodiment, a rotating ring 67 is fixedly installed above the rotary table 6, and a driven gear ring 66 is installed on the inner side of the rotating ring 67. The top of the lifting platform 63 is fixedly installed with a workstation switching motor 64 through a fixing bracket. A drive gear 65 is installed on the output shaft of the workstation switching motor 64. The drive gear 65 is meshed with the driven gear ring 66. Based on this, when the workstation switching motor 64 runs, it can drive the drive gear 65 to rotate. Since the drive gear 65 is meshed with the driven gear ring 66, the driven gear ring 66 drives the rotary table 6 to rotate through the rotating ring 67, thereby realizing the switching of workstations.

[0029] This embodiment discloses a trimming method for an automatic rotating trimming device for solar panels, the specific steps of which are as follows: S1: The solar panel is conveyed to the loading station via the feeding conveyor belt 2. At the loading station, the suction cup attachment 62 under the bracket 61 adsorbs the solar panel. S2: The station switching motor 64 runs, controlling the rotary table 6 to rotate 90 degrees, so that the solar panel reaches the long side trimming station. The hydraulic top 60 drives the rotary table 6 to move down until the solar panel is located above the suction cup material platform 303 and is attracted and fixed. The hydraulic top 60 drives the rotary table 6 to move up to avoid affecting the trimming. At this time, the suction cup material platform 303 slides along the length direction of the slide bar 304 under the drive of the first motion control unit 302. During this process, the blades 318 in the trimming units 315 located on both sides of the suction cup material platform 303 trim the long side of the solar panel until the trimming is completed. The first motion control unit 302 controls the suction cup material platform 303 to reset. The hydraulic top 60 drives the rotary table 6 to move down, and the suction cup attachment 62 below the bracket 61 attracts the solar panel on the long side trimming station. S3: The station switching motor 64 runs, controlling the rotary table 6 to rotate 90 degrees, so that the solar panel reaches the short side trimming station. Similarly, the short side of the solar panel is trimmed in the short side trimming station. S4: After the short side is trimmed, the suction cup attachment 62 will adsorb and transfer the trimmed solar panel onto the discharge conveyor belt 5, and then transmit it out through the discharge conveyor belt 5.

[0030] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
