Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic component manufacturing, and in particular to a photovoltaic component lamination positioning device. Background Art

[0002] In the production process of photovoltaic modules, the lamination process is one of the key steps. This process combines solar cells with glass, EVA film (ethylene-vinyl acetate copolymer), backplane and other materials tightly by heating and pressurizing to form a complete photovoltaic module. Accurate positioning during the lamination process has a decisive influence on the quality and performance of the final product.

[0003] At present, many photovoltaic module manufacturers need to accurately place a single glass plate at the corresponding position of the cell before the lamination process. Usually, the glass plate is transported to the lamination process by a conveyor. However, due to the high cost of automated equipment (such as robotic arms), many factories still use traditional manual operations. When placing glass plates, workers usually rely on measuring tools or visual judgment for positioning, but due to fatigue from long-term operation or other uncontrollable factors, positioning deviations are prone to occur, causing the glass plates to shift or overlap. This deviation will cause the surface of the component to be uneven during the subsequent lamination process, affecting the quality and performance of the product.

[0004] Therefore, there is an urgent need for a photovoltaic module lamination positioning device with an automatic adjustment function to solve the above problems. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a photovoltaic module lamination positioning device with an automatic adjustment function.

[0006] A photovoltaic module laminating positioning device comprises a conveyor base and a laminator, wherein a partition is provided in the middle of the conveyor base, a laminator is installed at the partition, an auxiliary base is installed between the laminator and the front conveyor base, a positioning mechanism for regulating the front and rear spacing of glass plates is provided on a truss in the middle of the auxiliary base, and the positioning mechanism comprises electric cylinders symmetrically installed inside the truss, positioning push plates on driving ends of each electric cylinder that are commonly connected and contact with multiple glass plates arranged in the same transverse direction, multiple connecting rod supports symmetrically arranged on the upper part of the positioning push plates, multiple guide plates symmetrically fixed at the rear of the upper part of the auxiliary base, and two guide plates close to each guide plate. The guide plate is provided with a distance-adjusting plate which is slidably connected to the truss on the side and the rear part of the auxiliary machine base, and each distance-adjusting plate is slidably connected to the hinge at the lower part of the corresponding connecting rod support. A correction mechanism capable of pushing apart the glass plates in the left and right stacked state is arranged in the front part of the guide plate, and the correction mechanism includes a contact rod fixed at the front part of the support of the connecting rod support, a guide seat fixed at the middle part of the upper part of the guide plate, a toggle plate slidably connected to the guide seat, two semicircular protrusions which are staggered up and down at the rear part of the toggle plate and are in sliding contact with the contact rod, and springs which are symmetrically arranged between the two sides of the toggle plate and the sliding part of the guide seat. In addition, the positioning mechanism is also provided with a dust removal mechanism for the auxiliary lamination process.

[0007] In a preferred embodiment of the present invention, the laminator includes a pressure platform for encapsulating photovoltaic modules, and a heating platform at the same height as the top surface of the conveyor base, a vacuum circulation tube that is arranged around the inside of the pressure platform and passes through to the outside, and linear modules on both sides of the outside of the laminator directly drive the pressure platform downward.

[0008] In a preferred embodiment of the present invention, each distance adjusting plate has an oblique slide groove on the upper part, and the two slide grooves at the same guide plate position are arranged opposite to each other, and the hinges on both sides of the lower part of each connecting rod support are fixedly connected with positioning rods that slide in cooperation with the slide groove.

[0009] In a preferred embodiment of the present invention, both side surfaces of each guide plate and each distance adjusting plate's front end are inclined, an opening is opened in the middle of each guide plate for limiting the position of the positioning push plate after it is lowered, and the upper portion of each guide plate is fixedly connected to the upper portion of the auxiliary machine base.

[0010] In a preferred embodiment of the present invention, the end of the contact rod close to the semicircular protrusion is spherical, and the spherical part is in sliding contact with the outer contour of the semicircular protrusion. When the positioning push plate is driven down by the electric cylinder, it drives the connecting rod support to rotate and drives the contact rod to descend at the same time, thereby generating a thrust on the semicircular protrusion, forcing the toggle plate to make a linear reciprocating motion along the guide seat and its sliding path in cooperation with the spring.

[0011] In a preferred embodiment of the present invention, the dust removal mechanism includes a plurality of groups of positioning parts symmetrically connected to the upper truss of the auxiliary machine base, and an extrusion rod slidably connected between each group of positioning parts, a piston fixed at the lower end of the extrusion rod, and an air collecting tank is arranged in front of each group of positioning parts. A pressure relief port is opened at the bottom of each air collecting tank, and the extrusion rod slides through the upper part of the air collecting tank, and the outer contour of the piston is completely adapted to the inner wall of the air collecting tank, as well as an air supply pipe extending horizontally outward and connected to the front side of the lower part of the air collecting tank, and a high-pressure nozzle is installed at the air outlet at the front end of the air supply pipe.

[0012] In a preferred embodiment of the present invention, a smoothing mechanism is further included which can push and flatten the glass plates in an upper and lower stacked state, the smoothing mechanism including a limit plate rotatably connected to the outer side of each toggle plate, wherein the two middle toggle plates are rotatable and relatively arranged on both sides of the same limit plate, and the lower part of the limit plate is in rotational contact with the glass plate, a torsion spring is provided at the rotational connection between each limit plate and the corresponding toggle plate, a motor corresponding to the rear position of each limit plate and also installed on the toggle plate, and a pushing wheel connected to the output end of the motor and in rotational contact with the surface of the glass plate.

[0013] In a preferred embodiment of the present invention, the front end of each gas pipe is bent downward, and the high-pressure nozzle and the front end of the gas pipe have the same inclination trend, and the gas outlet end of the high-pressure nozzle is provided with a diffusion sleeve nozzle.

[0014] The beneficial effects of the present invention are as follows: 1. Through the coordinated work of the positioning mechanism, the correction mechanism and the dust removal mechanism, the fully automatic and precise positioning of the glass plate before lamination is achieved. The positioning mechanism adjusts the lateral spacing of the glass plate through the positioning push plate driven by the electric cylinder to ensure uniform spacing of the components. The correction mechanism uses the reciprocating motion of the toggle plate to solve the lateral lamination problem. The dust removal mechanism uses high-pressure gas jets to clean the surface of the glass plate. This multi-mechanism coordinated automation method avoids human errors, improves positioning accuracy and efficiency, and provides reliable guarantee for subsequent lamination processes.

[0015] 2. The slide groove design of the positioning push plate and the distance adjustment plate driven by the electric cylinder realizes the automatic and precise adjustment of the distance between the glass plates, avoiding the errors caused by manual operation. When the positioning push plate descends, the distance adjustment plate drives the positioning rod to slide outward through the slide groove, pushing the glass plates to adjust the longitudinal spacing, ensuring the accurate position of each component, improving the consistency and quality of photovoltaic components, and reducing product defects caused by inaccurate positioning.

[0016] 3. The reciprocating linear motion of the toggle plate and the coordinated action of the limit plate and the push wheel effectively solve the stacking problem of the glass plates that may occur during the transmission process. The reciprocating motion of the toggle plate is driven by the positioning push plate and is achieved through the sliding contact between the contact rod and the semicircular protrusion, which can quickly adjust the horizontally stacked glass plates; the limit plate and the push wheel help the upper glass plate to separate from the lower layer and flatten it through rotation and friction, ensuring that all components are arranged flush, improving the success rate of the subsequent lamination process, and ensuring the flatness and aesthetics of the product.

[0017] 4. By positioning the push plate downward, the piston is driven to move downward in the gas collecting tank to generate high-pressure gas, which is released through the gas pipe and high-pressure nozzle to efficiently clean the surface of the glass plate. The design of the diffusion sleeve nozzle further optimizes the air flow distribution, improves the cleaning efficiency, ensures that the surface of the glass plate is dust-free, and prevents impurities from affecting the lamination quality, thereby improving the stability and reliability of the final product.

[0032] Embodiment: A photovoltaic module lamination positioning device, such as Figure 1-Figure 12As shown, it includes a conveyor base 1 and a laminator 11. The conveyor base 1 serves as the basic supporting structure of the photovoltaic module lamination positioning device, and is used to transmit the glass plate 100 and the EVA film to the lamination process. A partition is provided in the middle of the conveyor base 1, and the laminator 11 is installed at the partition. The laminator 11 is used to encapsulate the photovoltaic module, and the glass plate 100, the EVA film, the back plate and other materials are tightly combined by heating and pressurizing. An auxiliary base 12 is installed between the laminator 11 and the front conveyor base. A positioning mechanism 2 for adjusting the front and rear spacing of the glass plate 100 is provided on the truss in the middle of the auxiliary base 12. The positioning mechanism 2 includes electric cylinders 21 symmetrically installed inside the truss, and the driving ends of the electric cylinders 21 are connected together and arranged in the same horizontal direction. The positioning push plate 22 contacts multiple glass plates 100, and the positioning push plate 22 applies contact force to properly separate the glass plates 100 to avoid positioning deviation caused by too close spacing. A plurality of connecting rod supports 23 are symmetrically arranged on the upper part of the positioning push plate 22, a plurality of guide plates 24 are symmetrically fixed at the upper rear part of the auxiliary machine base 12, and a distance adjusting plate 25 that is close to both sides of each guide plate 24 and slidably connected to the truss at the rear part of the auxiliary machine base 12, each distance adjusting plate 25 is slidably connected to the hinge at the lower part of the corresponding connecting rod support 23, each guide plate 24 and the two side surfaces of the front end of each distance adjusting plate 25 are inclined, and an opening suitable for limiting the position of the positioning push plate 22 after it is lowered is opened in the middle of each guide plate 24, and the upper part of each guide plate 24 is connected to the auxiliary machine base 12 The upper part of the guide plate 24 is fixedly connected, and an oblique sliding groove 232 is opened on the upper part of each distance adjusting plate 25, and the two sliding grooves 232 at the same guide plate 24 position are arranged oppositely, and the hinges on both sides of the lower part of each connecting rod support 23 are fixedly connected with positioning rods 231 that slide with the sliding groove 232. Through the cooperation of the sliding groove 232 and the positioning rod 231, the precise movement of the distance adjusting plate 25 is achieved to ensure the uniformity of the longitudinal spacing of the glass plates 100; the correction mechanism 3 capable of shifting the glass plates 100 in the left and right stacked state is arranged at the front of the guide plate 24, and the correction mechanism 3 includes a contact rod 30 fixed at the front part of the support of the connecting rod support 23, a guide seat 31 fixed at the middle of the upper part of the guide plate 24, a toggle plate 32 slidably connected to the guide seat 31, and a toggle plate 32 at the rear Two semicircular protrusions 33 are staggered and arranged up and down and in sliding contact with the contact rod 30, and a spring 34 is symmetrically arranged between the two sides of the toggle plate 32 and the sliding position of the guide seat 31. The end of the contact rod 30 close to the semicircular protrusion 33 is spherical, and the spherical part is in sliding contact with the outer contour surface of the semicircular protrusion 33. When the positioning push plate 22 is driven down by the electric cylinder 21, it drives the connecting rod support 23 to rotate and drives the contact rod 30 to descend at the same time, thereby generating a thrust on the semicircular protrusion 33, forcing the toggle plate 32 to make a linear reciprocating motion along the sliding path of the guide seat 31 and the spring 34; in addition, the positioning mechanism 2 is also provided with a dust removal mechanism 5 for auxiliary lamination process, and the auxiliary machine base 12 is used to support the positioning mechanism 2, the correction mechanism 3 and the dust removal mechanism 5.

[0033] like Figure 1-Figure 3 As shown, the laminator 11 includes a pressure table 110 for packaging photovoltaic modules. The pressure table 110 is used to package the photovoltaic modules and apply pressure. The laminator 11 is a prior art, and a heating table 111 at the same height as the top surface of the conveyor base 1. The heating table 111 provides heat energy to assist the lamination process. A vacuum circulation pipe 112 is arranged around the inside of the pressure table 110 and passes through the outside. The vacuum circulation pipe 112 is used to exhaust air to ensure that no bubbles are generated during the lamination process, and the linear modules 113 on both sides of the outside of the laminator 11 directly drive the pressure table 110 to press down.

[0034] like Figure 1 , Figure 4 , Figure 5 , Fig.11 and Fig.12 As shown, the dust removal mechanism 5 includes a plurality of positioning members 50 symmetrically connected to the upper truss of the auxiliary machine base 12, the positioning members 50 ensure the stable installation and operation of the dust removal mechanism 5, and an extrusion rod 51 slidably connected between each group of positioning members 50, the extrusion rod 51 generates high-pressure gas by moving downward to provide power for dust removal, a piston 52 fixed at the lower end of the extrusion rod 51, and a gas collecting tank 53 is arranged at the front of each group of positioning members 50, the gas collecting tank 53 is used to store and release high-pressure gas, and a pressure relief port is opened at the bottom of each gas collecting tank 53, and the extrusion rod 51 slides The piston 52 is adapted to the inner wall of the gas collecting tank 53 and is used to generate air pressure, and the gas pipe 54 is horizontally extended outward and connected to the front side of the lower part of the gas collecting tank 53. The high-pressure nozzle 55 installed at the front end of the gas outlet of the gas pipe 54 releases the high-pressure gas to the surface of the glass plate 100 through the pressure relief port and the gas pipe 54 to achieve dust removal. The front end of each gas pipe 54 is bent downward, and the high-pressure nozzle 55 and the front end of the gas pipe 54 have the same inclination trend, and the gas outlet end of the high-pressure nozzle 55 is provided with a diffusion sleeve.

[0035] like Figure 1 , Figure 4 , Figure 5 , Figure 8 and Fig.10As shown, it also includes a smoothing mechanism 4 that can push and flatten the glass plates 100 in the upper and lower stacked state, and the smoothing mechanism 4 includes a limit plate 40 that is rotatably connected to the outer side of each toggle plate 32, and the limit plate 40 helps the upper glass plate 100 to separate from the lower layer and flatten through rotation and friction, wherein the two toggle plates 32 in the middle are rotated and relatively arranged on both sides of the same limit plate 40, and the lower part of the limit plate 40 is in rotational contact with the glass plate 100, and each limit plate 40 is in rotational contact with the corresponding toggle plate 3 2 are all provided with torsion springs 41 at the rotation connection, and the torsion springs 41 provide a rebound force to ensure that the limit plates 40 can automatically return to their positions after contacting the glass plate 100. A motor 42 corresponding to the rear position of each limit plate 40 and also installed on the toggle plate 32, and a push wheel 43 connected to the output end of the motor 42 and in rotational contact with the surface of the glass plate 100, the motor 42 drives the push wheel 43 to rotate, provides friction, and drives the glass plate 100 to move through the rotational friction force, so that it is out of the stacked state and flattened.

[0036] Before the lamination process of photovoltaic modules, the EVA film is transferred to the lamination device through the conveyor base 1. The worker needs to place the glass plate 100 at the corresponding position of the EVA film. When the glass plate 100 approaches the auxiliary base 12, the electric cylinder 21 drives the positioning push plate 22 to descend and adjust the spacing of the transversely arranged glass plates 100. If the transverse distance between the glass plates 100 is too close, the positioning push plate 22 will apply contact force to separate the glass plates 100 appropriately to ensure that the transverse spacing between each component is uniform. If the longitudinal spacing between the glass plates 100 is too small, the positioning push plate 22 will apply contact force to separate the glass plates 100 appropriately to ensure that the transverse spacing between each component is uniform. During the transmission process, their edges first contact the inclined surface of the front part of the guide plate 24, and then the inclined surface of the distance adjusting plate 25. At the same time, after the positioning push plate 22 is lowered, the connecting rod support 23 will also rotate upward, and the positioning rod 231 hinged to the two sides of the lower part of the connecting rod support 23 will be driven by the rotation force to slide outward along the slide groove 232, and at the same time, the two distance adjusting plates 25 will be driven to slide outward synchronously, no longer close to the guide plate 24, and the glass plate 100 close to the guide plate 24 is pushed by the sliding distance adjusting plate 25, ensuring the accurate movement of the distance adjusting plate 25; During the descending process of the positioning push plate 22, the spherical surface portion at the front end of the contact rod 30 contacts the two semicircular protrusions 33 on the toggle plate 32, driving the toggle plate 32 to generate reciprocating linear motion along the guide seat 31. This action can effectively adjust the glass plates 100 in a transversely stacked state so that they are arranged flush. Specifically, the spherical surface portion at the front end of the contact rod 30 first slides in contact with the outer contour surface of the semicircular protrusion 33 above the rear of the toggle plate 32, forcing the toggle plate 32 to slide to one side along the sliding path on the guide seat 31 under the action of the contact force, and squeezes the spring 34 on the corresponding side, so that the toggle plate 32 returns to its original position by a small distance, but the positioning push plate 22 is not moved. The positioning push plate 22 continues to descend, so the toggle plate 32 is not completely returned to its original position. The positioning push plate 22 that continues to descend will contact the outer contour surface of the semicircular protrusion 33 at the bottom again by the contact force, forcing the toggle plate 32 to slide to the other side, and squeeze the spring 34 on the corresponding side and repeat the above steps. At this time, the toggle plate 32 realizes reciprocating linear motion. In addition, when two of the transversely arranged glass plates 100 are in a transversely stacked state, the toggle plate 32 that performs reciprocating linear motion can toggle the glass plate 100 stacked on top of the other glass plate 100, so that it naturally descends and is flush with the adjacent glass plate 100. For the vertically stacked glass sheets 100, the limiting plate 40 and the pushing wheel 43 driven by the motor 42 work together to help the upper glass sheet 100 to separate from the lower layer and flatten through rotation and friction. The lower part of the limiting plate 40 is in rotational contact with the glass sheet 100, and a torsion spring 41 is provided to provide a rebound force. After the motor 42 is started, the pushing wheel 43 accelerates the rotation and generates friction with the surface of the glass sheet 100, slowly driving the glass sheet 100 to move, so that it is separated from the stacked state and gradually flattened. Before the glass plate 100 enters the lamination process, the dust removal mechanism 5 will clean its surface. As the positioning push plate 22 descends, the extrusion rod 51 on the dust removal mechanism 5 will drive the piston 52 to move downward in the gas collecting tank 53 during the process of the positioning push plate 22 descending. The piston 52 generates gas pressure in the gas collecting tank 53, and the gas is released from the high-pressure nozzle 55 through the gas pipe 54 to remove dust from the surface of the glass plate 100, ensuring that the surface of the glass plate 100 is dust-free and preventing impurities from affecting the lamination quality. Finally, the glass plate 100 that has been precisely positioned, corrected and dust-free is transferred to the laminator 11. Driven by the linear module 113, the pressure table 110 presses down with the heat energy provided by the heating table 111, and exhausts the air through the vacuum circulation pipe 112, ensuring that each component is tightly combined under heating and pressurized conditions, so as to improve the accuracy and efficiency of the photovoltaic component production process and ensure the stability and reliability of the product.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
