Description

Technical Field

[0001] This invention relates to the field of laser cutting, and more particularly to an online laser cutting device for photovoltaic modules. Background Technology

[0002] In the production and use of photovoltaic (PV) modules, cutting is required at multiple stages. Cutting is divided into deep cutting (complete cleavage) and shallow cutting (surface cleavage). Marking during shallow cutting is a crucial step in ensuring product quality, traceability, safety, and compliance. The most common locations for marking (shallow cutting) on ​​PV modules are usually in the corners or edges. The marking (shallow cutting) content mainly includes the manufacturer's name / trademark, product model, electrical parameters such as power (W), voltage (V), and current (A), serial number (SN) or production batch number (Lot No.), and certification marks (such as IEC, UL, CE, etc.). (etc.) and production date, etc.

[0003] Chinese patent document CN117600665B discloses an online laser marking device for photovoltaic modules, including a laser marking machine, a conveyor line, and a feeding device. The laser marking machine is used to mark the surface of photovoltaic module products. The laser marking machine mainly includes a chassis and a machine head. The conveyor line is used to transport photovoltaic module products. The feeding device is located at the beginning of the conveyor line and is used to feed photovoltaic module products. The laser marking moving part is used to grab the photovoltaic modules on the conveyor line, cut them with the laser marking machine, and then place the photovoltaic modules back on the conveyor line.

[0004] In existing technologies, online laser cutting devices for photovoltaic modules position the modules by applying force from the edges. Adjustments to the specific position during shallow cutting are also made by pushing the module from the outer positioning structure. However, the marking and cutting positions for photovoltaic modules are mostly at the edges and corners. External positioning and adjustments can affect the accuracy of the cutting position and may even obscure the cutting area, causing cutting errors. Summary of the Invention

The laser cutting box has an inlet on one side and an outlet on the other, with a laser cutting chamber inside. The inlet component passes through the inlet, and the outlet component passes through the outlet. A circulating conveyor is located within the laser cutting chamber, with one end below the inlet and the other above the outlet, reciprocating in a left-right direction. Positioning components are arranged in pairs on the circulating conveyor, enabling cyclical movement. Each set of positioning components includes a pair of positioning elements. The paired positioning elements have movable and rotatable positioning ends, cooperating with the inlet and outlet components for automatic feeding and discharging, and also clamping and positioning the photovoltaic module from the center, adjusting its position to expose the area to be cut. Two sets of exhaust guide seats are located at the top and bottom of the laser cutting chamber, respectively, and are connected to external exhaust equipment. Multiple sets of laser cutting components are arranged in parallel and staggered configurations, sliding along the conveying direction of the circulating conveyor on the upper and lower exhaust guide seats. The laser cutting head on the laser cutting component is designed to move vertically and horizontally for cutting.

[0006] Preferably, two sets of circulating transmission components are provided, located at the front and rear of the laser cutting chamber respectively; pairs of positioning components are respectively positioned in a mirror image of the two sets of circulating transmission components, and move synchronously.

[0007] Preferably, the positioning assembly includes a mounting base located between a pair of positioning members; the mounting base is provided with a translation drive for driving the two sets of positioning members to move relative to or away from each other, and a rotatable transmission drive that cooperates with the cyclic transmission member.

[0008] Preferably, the positioning component includes a mounting bracket located on the drive end of the translation drive component; the mounting bracket is provided with a rotatable mounting platform; both ends of the mounting platform are provided with telescopic rods; a rotatable positioning roller is provided between the two sets of telescopic rods; the positioning roller is the positioning end, and adjustment components for rotation adjustment, position adjustment and temperature adjustment are provided on both sides.

[0009] Preferably, the adjusting component includes an adjusting seat located at the end of the telescopic rod; a positioning roller is rotatably disposed at the center of the adjusting seat; a telescopic support rod is disposed around the outer periphery of the adjusting seat; a supporting suction hood is disposed at the end of the support rod, and a suction pump and a dust collection cylinder are disposed on one side of the support rod; the dust collection cylinder is connected to the supporting suction hood through a dust collection pipe.

[0010] Preferably, the smoke exhaust guide seat includes a seat body; the seat body is provided with multiple sets of smoke exhaust guide platforms in the front, middle and rear sections; the multiple sets of smoke exhaust guide platforms are connected to the air extraction equipment through exhaust pipes to exhaust smoke, and guide the movement of the laser cutting components.

[0011] Preferably, each of the multiple laser cutting components includes a laser cutting frame; one part of the multiple laser cutting frames is slidably mounted on the front and middle smoke exhaust guides via a drive component one, and another part is slidably mounted on the rear and middle smoke exhaust guides via a drive component one, and the multiple laser cutting frames are arranged parallel to each other and staggered; each laser cutting frame is equipped with an electrically controlled lifting platform; the electrically controlled lifting platform is equipped with a drive component two and a laser cutting head that moves horizontally in the front-back direction driven by the drive component two.

[0012] Preferably, the feeding component includes a feeding rack that passes through the feeding port; the discharge side of the feeding rack is located above the end of the circulating conveyor and is provided with a corresponding feeding channel; the feeding rack is provided with two sets of parallel and counter-rotating conveyor belts; each of the two sets of conveyor belts is provided with a corresponding spaced push plate on its outer side, and the two sets of conveyor belts are separated by the push plates to form a feeding channel that matches the photovoltaic module; the feeding channel is connected to the feeding channel at the end.

[0013] Preferably, the bottom of the feeding rack is provided with a movable door panel that is opposite to the position of the feeding chute.

[0014] Preferably, the discharge component includes a discharge rack that extends through the discharge port; the discharge end of the discharge rack is located below the tail of the circulating conveyor, and multiple sets of discharge rollers are provided on the discharge end.

[0015] Compared with existing technologies, this invention has the following beneficial technical effects: By using a circulating transmission component to drive the positioning assembly to move between the inlet, outlet, and upper and lower exhaust guide seats, online circulating cutting is achieved, with automatic feeding and discharging. During cutting, the distance between the upper and lower positioning rollers is adjusted by a translation drive component, and the position of the upper and lower positioning rollers is adjusted by the extension and retraction of the telescopic rod and the rotation of the mounting platform. Two pairs of positioning rollers clamp the photovoltaic module on the same side. The upper and lower support suction hoods extend and retract. The support suction hoods in contact with the photovoltaic module adjust the photovoltaic module to a horizontal position. Then, the positioning rollers move from the upper and lower sides of the photovoltaic module to the upper and lower center, cleaning the surface of the photovoltaic module during the movement. The support suction hoods not in contact with the photovoltaic module are used for dust suction cleaning of the edges of the photovoltaic module. After the positioning rollers move into position, they clamp and position the photovoltaic module from the center, exposing the edge area to be cut. Through the cooperation of the above structures, the cleaning and position adjustment of the photovoltaic module are achieved in one step to meet the requirements of edge cutting of the photovoltaic module. During cutting, the laser cutting frame and laser cutting head move along a vertical trajectory. The laser cutting heads located on the front and middle fume extraction guides primarily cut the front portion of the photovoltaic module. The laser cutting heads located on the rear and middle fume extraction guides primarily cut the rear portion of the photovoltaic module. The fume extraction guides collect the high-temperature fumes generated during the cutting process. Through the coordination of these structures, laser cutting and cooling / shaping of the photovoltaic module are achieved in one operation. Simultaneously, the upper and lower laser cutting heads can be configured to cut alternately or separately on the front and back sides, avoiding continuous operation of a single laser cutting head that could lead to high temperatures and affect the cutting effect. The entire online cutting process is cyclical, continuous, automatic, and efficient, suitable for laser cutting the corners or edges of the front and back of photovoltaic modules, and also suitable for complete cuts of photovoltaic modules.

[0028] Example 1: This invention proposes an online laser cutting device for photovoltaic modules, such as... Figures 1-4As shown, the system includes a laser cutting box 1, positioning components 6, a smoke exhaust guide seat 7, and a laser cutting assembly 8. The laser cutting box 1 has a feed inlet 101 on one side and a discharge outlet 102 on the other side, with a laser cutting chamber inside. A feed component 2 passes through the feed inlet 101; a discharge component 3 passes through the discharge outlet 102; a circulating conveyor 5 is located within the laser cutting chamber, with one end below the feed inlet 101 and the other end above the discharge outlet 102, reciprocating in a left-right direction; positioning components 6 are arranged in pairs on the circulating conveyor 5, achieving cyclical movement through the conveyor 5, and each set of positioning components 6 includes a pair of positioning elements 601; the paired positioning elements 601 are... The positioning end is movable and rotatable. On the one hand, it is matched with the feeding part 2 and the discharging part 3 for automatic feeding and discharging. On the other hand, it clamps and positions the photovoltaic module 10 from the middle and adjusts its position to expose the area to be cut. Two sets of exhaust guide seats 7 are located at the top and bottom of the laser cutting chamber, respectively, and are connected to the external exhaust equipment 4. Multiple sets of laser cutting components 8 are arranged in parallel and staggered front and back, and are slidably arranged on the upper and lower exhaust guide seats 7 along the transmission direction of the circulating transmission part 5. The laser cutting head 803 on the laser cutting component 8 is configured to be able to move up and down and move back and forth for cutting.

[0029] like Figure 4 As shown, two sets of circulating transmission components 5 are set up, located at the front and rear of the laser cutting chamber respectively; pairs of positioning components 6 are respectively positioned in a mirror image of the two sets of circulating transmission components 5, and move synchronously.

[0030] The circulating transmission component 5 is set as a ring track, and the moving trajectory connects the feed port 101, the discharge port 102, and the upper and lower smoke exhaust guide seats 7, so that the photovoltaic module 10 is automatically fed, clamped and fixed, and can be subjected to online circulating laser cutting after the position is adjusted. After cutting, it is automatically unloaded.

[0031] like Figure 5 As shown, the positioning component 6 includes a mounting base 602 located between a pair of positioning members 601; the mounting base 602 is provided with a translation drive for driving the two sets of positioning members 601 to move relative to or away from each other, and a rotatable transmission drive that cooperates with the circulating transmission member 5.

[0032] The translation drive is set as a double-headed, bidirectional cylinder, with two sets of telescopic rods connected to two sets of positioning components 601 respectively, driving the two sets of positioning components 601 to move synchronously and in opposite directions to adjust the spacing to match the size of the photovoltaic module 10; the transmission drive is set as an electric wheel structure that moves along a ring track, driving the photovoltaic module 10 to move between the feed port 101, the discharge port 102 and the upper and lower exhaust guide seats 7, and at the same time connected to the mounting base 602 through an electrically controlled rotation structure, so that the mounting base 602 can adjust the angle of the photovoltaic module 10 by rotating during the movement to meet the needs of feeding, discharging and cutting.

[0033] like Figure 5 As shown, the positioning component 601 includes a mounting bracket 604 located on the driving end of the translation drive component; the mounting bracket 604 is provided with a rotatable mounting platform 603 driven by a motor; both ends of the mounting platform 603 are provided with telescopic rods 605; a rotatable positioning roller 607 is provided between the two sets of telescopic rods 605; the positioning roller 607 is the positioning end, and adjustment components 606 for rotation adjustment, position adjustment and temperature adjustment are provided on both sides.

[0034] It should be further explained that the telescopic rod 605 is set as an L-shaped electrically controlled telescopic structure, and the angle and position of the positioning roller 607 can be adjusted with multiple degrees of freedom.

[0035] During positioning, the four sets of positioning rollers 607 are arranged in two layers, with two sets in each layer, located above and below the photovoltaic module 10 respectively. The distance between the upper and lower positioning rollers 607 is adjusted by the translation drive, and the position of the upper and lower positioning rollers 607 is adjusted by the extension and retraction of the telescopic rod 605 and the rotation of the mounting platform 603. The positioning rollers 607 move from the upper and lower sides of the photovoltaic module 10 to the upper and lower center, and the surface of the photovoltaic module 10 can be cleaned during the movement. After moving into position, the photovoltaic module 10 can be clamped and positioned from the center, while the edge area to be cut is exposed.

[0036] like Figure 6 As shown, the adjusting component 606 includes an adjusting seat 60601 located at the end of the telescopic rod 605; a positioning roller 607 is driven by a motor and rotatably disposed at the center of the adjusting seat 60601; a retractable support rod 60603 driven by a cylinder 60602 is arranged around the outer periphery of the adjusting seat 60601; a supporting suction hood 60604 is provided at the end of the supporting rod 60603, and a suction pump and a dust collection cylinder 60606 are connected to one side of the supporting rod 60603; the dust collection cylinder 60606 is connected to the supporting suction hood 60604 through a dust collection pipe 60605.

[0037] During feeding, the positioning components 6 move to below the feeding component 2, which is the end of the circulating conveyor 5. At this time, a pair of positioning components 6 are in a vertical state and located on both sides of the photovoltaic module 10 to be fed, with the spacing adapted to the width of the photovoltaic module 10. The fed photovoltaic module 10 falls, and the two sets of positioning rollers 607 (one at the front and one at the back) on the same side first clamp the front and back sides of the photovoltaic module 10 from both sides ("clamping on both sides in pairs", four-point clamping). At this time, the photovoltaic module 10 is in a suspended state. Then, the L-shaped structure of the telescopic rod 605 pushes the positioning rollers 607 to move towards the middle of the photovoltaic module 10. At the same time, the upper and lower support suction hoods 60604 extend and retract. The support suction hoods 60604 in contact with the photovoltaic module 10 adjust the photovoltaic module 10 to be horizontal. The whole process is a dynamic and active adjustment, not dependent on "momentary coincidence".

[0038] The support suction hood 60604, which does not contact the photovoltaic module 10, is used for dust removal and cleaning of the edges of the photovoltaic module 10 and for cooling after cutting. Before cutting, the photovoltaic module 10 can be positioned and thoroughly cleaned by rotating and moving the positioning roller 607.

[0039] like Figure 7 As shown, the smoke exhaust guide seat 7 includes a seat body 701; the seat body 701 is provided with multiple sets of smoke exhaust guide platforms 702 in the front, middle and rear sections; the multiple sets of smoke exhaust guide platforms 702 are connected to the air extraction device 4 through the exhaust pipe 9 to exhaust smoke, and guide the movement of the laser cutting component 8 on the other hand.

[0040] It should be further explained that the exhaust guide platform 702 is set in three sets, and each set of exhaust guide platform 702 is equipped with an exhaust trough; the trough opening faces upward and is equipped with a slag-blocking net, and the bottom of the trough is connected to the exhaust pipe 9.

[0041] During cutting, the upper and lower exhaust guide tables 702 collect the high-temperature fumes generated during the cutting process, accelerating the cooling of the laser cutting head 803 and the photovoltaic module 10 after cutting. Simultaneously, the laser cutting head 803 moves along the upper and lower exhaust guide tables 702.

[0042] like Figure 8 As shown, each of the multiple laser cutting components 8 includes a laser cutting frame 801; a portion of the multiple laser cutting frames 801 is slidably mounted on the front and middle smoke exhaust guide platforms 702 via a drive component 1, and another portion is slidably mounted on the rear and middle smoke exhaust guide platforms 702 via a drive component 1. The multiple laser cutting frames 801 are arranged parallel to each other and staggered; each laser cutting frame 801 is equipped with an electrically controlled lifting platform 802; the electrically controlled lifting platform 802 is equipped with a drive component 2 and a laser cutting head 803 that moves horizontally in the front-back direction driven by the drive component 2.

[0043] Both drive components one and two are lead screw structures, which drive the laser cutting frame 801 and the laser cutting head 803 to move along a vertical trajectory through the rotation of the corresponding lead screws. The laser cutting head 803, located on the front and middle smoke exhaust guide 702, primarily cuts the front portion of the photovoltaic module 10. The laser cutting head 803, located on the rear and middle smoke exhaust guide 702, primarily cuts the rear portion of the photovoltaic module 10. This segmented cutting of the photovoltaic module 10 improves cutting efficiency and effectiveness while reducing the workload of the laser cutting head 803, thus ensuring its performance. Because the laser cutting head 803 constantly moves on the laser cutting frame 801 during cutting, smoke collection and exhaust can be more targeted and efficient.

[0044] like Figures 9-10As shown, the feeding component 2 includes a feeding rack 201 that passes through the feeding port 101; the discharge side of the feeding rack 201 is located above the end of the circulating conveyor 5 and is provided with a corresponding feeding channel; the feeding rack 201 is provided with two sets of parallel and counter-rotating conveyor belts 202; each of the two sets of conveyor belts 202 is provided with a corresponding spaced push plate 203 on its outer side, and the two sets of conveyor belts 202 are separated by the push plate 203 to form a feeding channel that matches the photovoltaic module 10; the feeding channel is connected to the feeding channel at the end.

[0045] During feeding, the workers place the photovoltaic modules 10 one by one into the feeding channel. Two sets of conveyor belts 202 rotate in opposite directions, and their push plates 203 divide the feeding channel into sections matching the size of the photovoltaic modules 10. This propels the photovoltaic modules 10 towards the feeding trough within the feeding channel. Limited by the push plates 203, the photovoltaic modules 10 maintain a vertical posture and enter the laser cutting chamber from the feeding trough, where they are clamped by the positioning rollers 607.

[0046] It should be further explained that the bottom of the feeding rack 201 is provided with a movable door plate 204 opposite to the feeding channel. By moving the door plate 204, the opening and closing and the size of the feeding channel are controlled, thereby controlling the photovoltaic module 10 to maintain a vertical falling trajectory and avoid tilting.

[0047] like Figure 11 As shown, the discharge component 3 includes a discharge rack 301 that passes through the discharge port 102; the discharge end of the discharge rack 301 is located below the tail of the circulating transmission component 5, and multiple sets of discharge rollers 302 are provided on the discharge end; during discharge, the positioning roller 607 releases its clamp on the photovoltaic module 10, allowing it to fall onto the discharge roller 302, and then moves out of the laser cutting chamber as the discharge roller 302 rotates.

[0048] It should be further explained that the positioning roller 607 is not released completely instantaneously when the clamp is released, but is kept in contact with the module by the support suction cover 60604 of the adjusting component 606. The support suction cover 60604 first extends to support the bottom surface of the photovoltaic module 10 under the drive of the support rod 60603, and then the positioning roller 607 is gradually released to avoid direct fall.

[0049] It should be further explained that an elastic layer (such as a rubber coating) can be provided on the surface of the discharge roller 302. When the photovoltaic module 10 falls, it is guided by the support suction cover 60604 to slide at an angle rather than in a vertical free fall manner and contact the discharge roller 302.

[0050] It should be further noted that the discharge rack 301 is located directly below the tail of the circulating conveyor 5, and the distance between the height of the discharge end and the clamping position of the positioning component 6 is extremely small. Combined with the support of the air suction hood 60604, the falling height of the component is controllable (usually ≤10cm).

[0051] Example 2: Based on the online laser cutting device for photovoltaic modules in Example 1, this example proposes an online laser cutting method for photovoltaic modules, the steps of which are as follows:

[0052] S1. The staff places the photovoltaic modules 10 one by one into the feeding channel. The two sets of conveyor belts 202 rotate in opposite directions, pushing the photovoltaic modules 10 towards the feeding trough. The photovoltaic modules 10 enter the laser cutting chamber from the feeding trough.

[0053] S2. A pair of positioning components 6 move to the bottom of the feeding trough and are in a vertical position. After the feeding photovoltaic module 10 falls, the distance between the upper and lower positioning rollers 607 is adjusted by the translation drive component. The position of the upper and lower positioning rollers 607 is adjusted by the extension and retraction of the telescopic rod 605 and the rotation of the mounting platform 603. Two of the four sets of positioning rollers 607 clamp the photovoltaic module 10 on the same side. The upper and lower support suction hoods 60604 extend and retract. The support suction hoods 60604 in contact with the photovoltaic module 10 adjust the photovoltaic module 10 to a horizontal position.

[0054] S3. The positioning roller 607 moves from the upper and lower sides of the photovoltaic module 10 to the upper and lower center. During the movement, the surface of the photovoltaic module 10 can be cleaned. The support suction hood 60604, which does not contact the photovoltaic module 10, is used to vacuum and clean the edges of the photovoltaic module 10. After the positioning roller 607 moves into place, it can clamp and position the photovoltaic module 10 from the center, while exposing the edge area to be cut.

[0055] S4. The positioned photovoltaic module 10 moves along the circulating conveyor 5 to a position opposite to the lower exhaust guide 702. The laser cutting frame 801 and the laser cutting head 803 move along a vertical trajectory. The laser cutting head 803 on the exhaust guide 702 located at the front and middle mainly cuts the front area of ​​the photovoltaic module 10. The laser cutting head 803 on the exhaust guide 702 located at the rear and middle mainly cuts the rear area of ​​the photovoltaic module 10. The exhaust guide 702 collects the high-temperature fumes during the cutting process.

[0056] S5. The positioned photovoltaic module 10 moves along the circulating conveyor 5 to the discharge port 102; the positioning roller 607 releases its grip on the photovoltaic module 10, allowing it to fall onto the discharge roller 302, and then moves out of the laser cutting chamber as the discharge roller 302 rotates.

[0057] S6. Repeat the above online process. The upper and lower laser cutting heads 803 can be set to cut alternately or to cut the front and back sides separately.

[0058] The above method is also applicable to the complete cutting of photovoltaic modules.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
