Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module manufacturing, and particularly to a continuous handling device for photovoltaic module lamination production. Background Art

[0002] At present, with the booming development of the photovoltaic industry, the production process of photovoltaic modules has become a key factor determining the quality and efficiency of the industry's development. Among them, the common four-layer structure double-glass photovoltaic module is composed of a lower tempered glass, a glue film, a battery string, and an upper tempered glass. As a core link, the lamination process aims to tightly bond these structures to form an integral structure with stable electrical properties and effective resistance to external environmental influences (such as moisture, ultraviolet rays, dust, etc.).

[0003] Currently, the lamination process of photovoltaic modules is mainly completed by a laminator. Its operation process usually involves precisely stacking each layer of materials in sequence, from bottom to top, namely the lower tempered glass, the glue film, the battery string, and the upper tempered glass. Subsequently, the stacked module is sent into the laminator for lamination treatment by means of a conveying device. During this process, some production links rely on handling equipment to achieve the grasping, placement of the battery string, and the encapsulation of the upper glass. However, the existing handling technology has obvious drawbacks, and there is a lack of an effective coordination mechanism among various processes.

[0004] Specifically, during the assembly process of the lower tempered glass, the battery string, and the upper tempered glass, the handling equipment responsible for different processes operates independently and lacks unified scheduling and coordination. This results in extremely unsmooth connections between processes, with obvious pauses and waiting times frequently occurring. For example, when the battery string handling equipment finishes placing the battery string, it needs to wait for the upper glass handling equipment to be in place. During the waiting process, the conveying device is in an idle state, causing waste of time and equipment resources. This non-continuous production mode severely restricts the improvement of the overall production efficiency, prolongs the production cycle, and keeps the production cost high. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the technical problem to be solved is to provide a continuous handling device for photovoltaic module lamination production.

[0006] Technical solution: A continuous handling device for lamination production of photovoltaic modules, including a chassis, a support frame, a conveyor, and a pusher block. The chassis serves as the basic framework of the entire device, and a support frame is installed at the middle position of its top. A conveyor is arranged in the middle of the chassis, and multiple pusher blocks are connected at equal intervals on the belt of the conveyor. It also includes a first slide rail, a moving block, a lifting frame, an electric suction cup, a power component, and a storage component. Storage components are provided on the front and rear sides of the chassis. The right side of the support frame is symmetrically connected with first slide rails, and moving blocks are slidably connected to the first slide rails. Lifting frames are further slidably connected to the moving blocks. Electric suction cups are installed at the bottoms of the lifting frames, and a spring-assisted height adaptive mechanism is arranged on the suction cups of the electric suction cups. A power component is provided on the support frame.

[0007] Further, the electric suction cup is driven by a drive motor.

[0008] Further, the power component includes a rotating shaft, a gear, a servo motor, and a positioning rod. The left side of the support frame is symmetrically and rotatably connected with rotating shafts, and gears are connected to the rotating shafts. A servo motor is installed at the rear side of the left part of the support frame, and the output shaft of the servo motor is connected to the rear rotating shaft. Horizontal grooves are opened on the inner sides of the gears. Positioning rods are connected to the upper ends of the lifting frames, and the positioning rods are slidably clamped with the corresponding horizontal grooves. N-shaped grooves are respectively opened at positions on the support frame aligned with the two gears, and the positioning rods penetrate through the N-shaped grooves and are slidably clamped with them.

[0009] Further, the storage component includes a material conveyor and a positioning frame. Material conveyors are installed at positions on the top of the chassis on the front and rear sides of the conveyor. Positioning frames are connected to the right sides of the tops of the outer frames of the material conveyors. The positioning frames are in an eight-shaped structure and are located outside the belts of the material conveyors.

[0010] Further, it also includes a stacking frame and a protruding part. The left side of the support frame is connected with a stacking frame for stacking upper-layer glass. Protruding parts are connected to the middle parts of the pusher blocks. A chute is opened in the middle of the bottom of the stacking frame, and a positioning groove is also opened on the left side of its bottom. The positioning groove communicates with the chute, and the sizes of the protruding part and the chute match.

[0011] Further, it also includes a contact rod and a pressing wheel. Diagonal contact rods are symmetrically and rotatably connected to the front and rear sides of the left side of the stacking frame, and pressing wheels are rotatably connected to the lower ends of the contact rods. A torsion spring is provided at the connection between the contact rod and the stacking frame and remains in a pre-tightened state.

[0012] Further, it further includes a second slide rail, a sliding frame, a follower, a tension spring, a centering block and a positioning block. The second slide rails are symmetrically installed at the front and rear of the lower part of the support frame. The sliding frames are slidably connected to the second slide rails. The followers are connected to the inner sides of the sliding frames. The followers penetrate through the right side of the support frame and form a sliding connection structure with the support frame. The lifting frame abuts against the follower on the same side. Tension springs are connected between the two sliding frames and the support frame. Centering blocks are respectively connected to the sides of the lower ends of the sliding frames close to each other. The centering blocks are located on the front and rear sides of the conveyor. Positioning blocks are connected to the left sides of the lower parts of the sliding frames.

[0013] Further, the inner side surface of the positioning block is designed to be inclined.

[0014] Compared with the prior art, the present invention has the following advantages: 1. First, the lower tempered glass encapsulated with the glue film is conveyed to the designated station by the conveyor, and then the battery string is automatically encapsulated on the lower tempered glass by the electric suction cup. Subsequently, the upper tempered glass is pushed by the convex part to complete the automatic encapsulation. The whole process realizes the continuous assembly of the lower tempered glass, the battery string and the upper tempered glass. The operation is coherent and smooth, significantly improving the production efficiency and meeting the requirements of large-scale production.

[0015] 2. Structures such as the centering block, the positioning block and the inclined surface design center and position the lower tempered glass, ensuring the accuracy when the battery string is encapsulated on the lower tempered glass and avoiding quality problems caused by position deviation.

The electric suction cup is equipped with a spring-assisted height self-adaptive mechanism, which can automatically adjust the adsorption height according to the change of the stacking height of the materials, maintain a stable adsorption force, is applicable to battery string materials with different stacking heights, and ensures the continuous progress of production.

[0017] 4. The design of the abutting rod and the pressing wheel can preliminarily laminate the photovoltaic module during the conveying process, closely fit the four structures of the lower tempered glass, the glue film, the battery string and the upper tempered glass, reduce the working burden of the subsequent laminator, and improve the overall production efficiency.

[0033] The following specifically introduces the present invention in combination with the accompanying drawings and specific embodiments.

[0034] Embodiment 1: A continuous handling device for the lamination production of photovoltaic modules, as shown in Figures 1-7 Figure 1. It includes a chassis 1, a support frame 101, a conveyor 102, a pusher block 103, a first slide rail 201, a moving block 202, a lifting frame 203, an electric suction cup 204, a power assembly and a storage assembly. The chassis 1 serves as the basic framework of the entire device, and a support frame 101 is firmly installed at the middle position of its top for carrying other components. A conveyor 102 is arranged in the middle of the chassis 1, and multiple pusher blocks 103 are equidistantly connected to the belt of the conveyor 102 for pushing the photovoltaic modules to move along a predetermined path. Storage assemblies are provided on the front and rear sides of the chassis 1 for storing battery strings. The right side of the support frame 101 is symmetrically connected with first slide rails 201 at the front and rear. Moving blocks 202 are slidably connected to the first slide rails 201. Lifting frames 203 are further slidably connected to the moving blocks 202. Electric suction cups 204 are installed at the bottoms of the lifting frames 203. A spring-assisted height adaptive mechanism is provided on the suction cups of the electric suction cups 204. This mechanism allows the suction cups to automatically adjust their positions according to the different stacking heights of the materials while maintaining a stable adsorption force. It is worth mentioning that the electric suction cup 204 is driven by a drive motor, which is different from the simple electromagnetic adsorption method. It can precisely adjust its working state through an intelligent control system, automatically adjust the suction force according to the material height, and greatly optimize the adsorption effect. A power assembly is provided on the support frame 101.

[0035] As shown in Figures 3-7 Figure 2. The power assembly includes a rotating shaft 301, a gear 302, a servo motor 303 and a clamping rod 305. The left side of the support frame 101 is symmetrically rotatably connected with rotating shafts 301 at the front and rear. Gears 302 are connected to the rotating shafts 301. A servo motor 303 is installed at the rear side of the left part of the support frame 101, and the output shaft of the servo motor 303 is connected to the rear rotating shaft 301. Horizontal grooves 304 are opened on the inner sides of the gears 302. Clamping rods 305 are connected to the upper ends of the lifting frames 203. The clamping rods 305 are slidably clamped with the corresponding horizontal grooves 304. N-shaped grooves 306 are respectively opened on the support frame 101 at positions aligned with the two gears 302. The clamping rods 305 pass through the N-shaped grooves 306 and are slidably clamped with them.

[0036] As shown in Figure 1 Figure 3. The storage assembly includes a material conveyor 104 and a positioning frame 105. Material conveyors 104 are installed at the positions on the top of the chassis 1 on the front and rear sides of the conveyor 102. Positioning frames 105 are connected to the right sides of the tops of the outer frames of the material conveyors 104. The positioning frames 105 have a unique eight-shaped structure and are located outside the belts of the material conveyors 104, which can accurately limit the battery strings to ensure their positions are accurate.

[0037] The photovoltaic module is composed of a four-layer structure, namely, a lower layer of tempered glass, a film, a battery string and an upper layer of tempered glass. When the device is used for the production lamination of photovoltaic modules, the lower layer of tempered glass pre-sealed with the film is transported to the left one by one by the conveyor 102, and the stacked battery string materials are synchronously transported by the material conveyors 104 on the front and rear sides. The battery string is transported from left to right by the material conveyor 104 until it is closely abutted against the positioning frame 105, thereby ensuring the accuracy of the position, so as to attach Figure 1 For reference, the working state at this time is: the electric suction cup 204 accurately sucks the battery string onto the lower layer of tempered glass encapsulated with the adhesive film. The role of the adhesive film is to achieve a firm bond and seal between the lower layer of tempered glass and the battery string. After the assembly of the battery string is completed, the electric suction cup 204 is controlled to unload the force, release the battery string, and then the servo motor 303 is started. The output shaft of the servo motor 303 rotates to drive the rear shaft 301 to rotate synchronously, thereby driving the two mutually meshing gears 302 to rotate, and the front shaft 301 also rotates accordingly. The two gears 302 push the positioning rod 305 and the lifting frame 203 to move synchronously through the transverse groove 304. Since the positioning rod 305 is limited by the n-type groove 306, it will slide upward first, thereby driving the electric suction cup 204 to move upward and disengage it from the battery string. After the electric suction cup 204 is completely out of contact with the battery string, the conveyor 102 is immediately started, and the photovoltaic component continues to be transported to the next process to the left through the push block 103 for subsequent processing, while the lower layer of tempered glass of the unpackaged battery string is transported to the center position to wait for packaging. After the electric suction cup 204 rises, the gear 302 continues to rotate to drive the positioning rod 305, the lifting frame 203, the electric suction cup 204 and the moving block 202 to move horizontally outward, and the moving block 202 slides smoothly along the first slide rail 201. When it moves to the top of the material conveyor 104, the gear 302 continues to rotate to make the positioning rod 305, the lifting frame 203 and the electric suction cup 204 move downward, and the electric suction cup 204 contacts the battery string on the material conveyor 104, and absorbs the battery string through the electric suction cup 204, and then controls the servo motor 303 to operate in the reverse direction, driving the electric suction cup 204 to move back to the center station along the n-type groove 306 trajectory, ready to package the new battery string on the new lower layer of tempered glass, such operation can be carried out continuously, and as the battery strings on the material conveyor 104 gradually decrease, the stacking height will change, and the spring-assisted height adaptive mechanism on the electric suction cup 204 can automatically adjust the suction cup position according to the height of the material to ensure that the adsorption force is stable and the operation effect will not be affected by height changes. The entire device realizes the continuous production and packaging of photovoltaic modules through the close cooperation between the conveyor 102 and the servo motor 303, greatly improving the production efficiency and quality.

[0038] Embodiment 2: Based on embodiment 1, Figures 8-11As shown in the figure, it further includes a stacking frame 401, a convex portion 404, an abutting rod 501, and a pressing wheel 502. The stacking frame 401 is connected to the left side of the support frame 101 and is used for stacking upper-layer glass. The middle parts of the pushing blocks 103 are all connected with the convex portion 404. A chute 402 is opened in the middle of the bottom of the stacking frame 401, and a positioning groove 403 is also opened on the left side of its bottom. The positioning groove 403 communicates with the chute 402. The size of the convex portion 404 is precisely matched with that of the chute 402 to ensure the precise cooperation between the two. The left side of the stacking frame 401 is symmetrically and rotatably connected with inclined abutting rods 501 in the front and back. The lower ends of the abutting rods 501 are all rotatably connected with pressing wheels 502. A torsion spring is provided at the connection between the abutting rod 501 and the stacking frame 401 and remains in a pre-tightened state to ensure that the abutting rod 501 and the pressing wheel 502 always apply a downward thrust.

[0039] The upper-layer tempered glass is pre-stacked in the stacking frame 401. When the lower-layer tempered glass on the conveyor 102 completes the encapsulation of the battery string, the conveyor 102 continues to convey the photovoltaic module to the left. At this time, the convex portion 404 on the pushing block 103 will precisely cooperate with the chute 402 at the bottom of the stacking frame 401 and contact the bottommost upper-layer tempered glass in the stacking frame 401. As the pushing block 103 moves smoothly, the convex portion 404 strongly pushes the upper-layer tempered glass to move horizontally to the left until the left end of the upper-layer tempered glass successfully passes through the positioning groove 403 and precisely contacts the photovoltaic module on the conveyor 102, and then precisely fits above the battery string. Thus, the automatic encapsulation operation of the upper-layer tempered glass is completed. When the bottommost upper-layer tempered glass is successfully pushed, the remaining glass in the stacking frame 401 will naturally move down one grid as a whole due to gravity, making full preparations for the subsequent encapsulation operation. As the pushing block 103 continues to move, the photovoltaic module will contact the pressing wheel 502. The photovoltaic module pushes up the pressing wheel 502, causing the abutting rod 501 to rotate upward around the connection point. Since the torsion spring is always in a pre-tightened state, the pressing wheel 502 always maintains a stable downward pressing force, effectively laminating the four structures of the photovoltaic module together initially. The rotatable design of the pressing wheel 502 ensures that the photovoltaic module can move smoothly without getting stuck due to excessive pressing force. The external laminator can be installed on the left side of the conveyor 102. The encapsulated photovoltaic module is smoothly conveyed to the laminator through the conveyor 102 for the final lamination and fixing process, thereby ensuring that the photovoltaic module has good firmness and excellent durability.

[0040] As Figures 12-14As shown in the figure, it further includes a second slide rail 601, a sliding frame 602, a follower 603, a tension spring 604, a centering block 605 and a top block 606. The second slide rails 601 are symmetrically installed at the front and rear of the lower part of the support frame 101. The sliding frames 602 are slidably connected to the second slide rails 601. The followers 603 are connected to the inner sides of the sliding frames 602. The followers 603 penetrate through the right side of the support frame 101 and form a sliding connection structure with the support frame 101. The lifting frame 203 abuts against the follower 603 on the same side. Tension springs 604 are connected between the two sliding frames 602 and the support frame 101. When the sliding frame 602 is pushed by an external force, the tension spring 604 is stretched accordingly, thereby storing elastic potential energy. When there is no external force, the tension spring 604 can drive the sliding frame 602 to automatically reset by virtue of its own elastic restoring force. Centering blocks 605 are respectively connected to the sides of the lower ends of the sliding frames 602 that are close to each other. These two centering blocks 605 are located on the front and rear sides of the conveyor 102 and are mainly used for precisely centering the position of the lower-layer tempered glass. Top blocks 606 are respectively connected to the left sides of the lower parts of the sliding frames 602. The function of the top blocks 606 is to limit the moving position of the photovoltaic module, so as to ensure that the parking position of the photovoltaic module during the conveying process is accurate. The inner side surface of the top block 606 is designed to be inclined, and it can correct the photovoltaic module when it deviates due to the inertia of the conveyor 102.

[0041] During the operation of the electric suction cup 204 conveying the battery string on the material conveyor 104 to the lower layer of tempered glass for packaging, the positioning rod 305 drives the lifting frame 203 and the electric suction cup 204 to move inward. During this process, the lifting frame 203 will push the follower 603 to move inward synchronously, and then drive the sliding frame 602 to slide inward along the second slide rail 601 through the follower 603. As the sliding frame 602 moves, the tension spring 604 is gradually stretched to store elastic potential energy. At the same time, the sliding frame 602 drives the centering block 605 and the top block 606 connected to its lower end to move inward, and the centering block 605 begins to play a role, and accurately adjusts the position of the lower layer of tempered glass to ensure that the lower layer of tempered glass is in the center position of the conveyor 102. The subsequent packaging operation provides a precise positioning basis. The top block 606 is against the left side of the glass at this time. When the conveyor 102 is suspended, if the glass is offset due to inertia, the inclined surface of the inner side of the top block 606 will immediately play a corrective role to restore the glass to the correct position. Then, the electric suction cup 204 will accurately encapsulate the sucked battery string on the lower layer of tempered glass. After the packaging is completed, the electric suction cup 204 first lifts upward and then moves outward to reset. At this time, the lifting frame 203 also moves outward and no longer presses against the follower 603. The tension spring 604 rebounds and resets with the elastic potential energy stored before, driving the sliding frame 602, the follower 603, the centering block 605 and the top block 606 to move outward and reset, thereby releasing the positioning restriction on the photovoltaic module. At this point, the photovoltaic module that has completed the battery string packaging can continue to move to the left under the action of the conveyor 102 and smoothly enter the next process for further processing.
