Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic modules, and particularly relates to an integrated machine for frame taking, frame moving and frame loading for the lamination frame reflux of photovoltaic modules. Background Art

[0002] The lamination process of photovoltaic modules is the core link in module manufacturing. Its purpose is to bond solar cells, encapsulation materials (such as EVA film), glass and backsheets into a whole through high temperature and high pressure to ensure the sealing, weather resistance and long-term reliability of the modules. At the same time, during lamination, in order to ensure no misalignment during lamination, a lamination frame is usually configured, that is, glass, EVA, solar cells, EVA and backsheets are placed in the lamination frame for pressing. After pressing is completed, it is necessary to separate the lamination frame from the solar photovoltaic module.

[0003] Currently, the conventional operation process for lamination frame reflux is as follows: First, send the laminated photovoltaic module to the reflux station, take the frame and place the frame statically above the reflux station, keeping the lamination frame in a horizontal state; then, send the photovoltaic module to be framed into the reflux station and perform rectification processing to align the lamination frame with the photovoltaic module below; finally, lower the lamination frame and load it onto the photovoltaic module. Although the above implementation process can meet the basic operations of reflux, there are the following technical defects:

[0004] 1) In the reflux station, it is necessary to alternately supply the laminated photovoltaic module and the photovoltaic module to be framed. Once there is an error in the alternate supply, it will cause the reflux of the lamination frame to be disordered, and it is impossible to perform pipeline operation, which not only results in low efficiency of the lamination frame reflux, but also has a high probability of reflux disorder.

[0005] 2) In the adopted frame taking method, most use the method of vacuum adsorption to provide adsorption force to adsorb the lamination frame, and then lift the lamination frame while maintaining adsorption. However, this method has a great potential safety hazard. Once the adsorption point falls off or shifts during movement, it is very easy to cause the risk of accidental falling of the lamination frame. Therefore, the probability of damage to the photovoltaic module is relatively high. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new integrated machine for frame taking, frame moving and frame loading for the lamination frame reflux of photovoltaic modules.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A frame taking, frame moving and frame installation integrated machine for photovoltaic module lamination frame reflow, comprising a frame taking device, a frame moving transfer device and a frame installation device, wherein the frame taking device comprises a frame taking station, a hooking unit and a receiving unit, wherein the frame taking station has a transmission component; the receiving unit can lift the lamination frame upward and separate it from the laminated photovoltaic module; the hooking unit is located at one end of the transmission component, keeps the hooking center aligned with the center of a long side or a short side of the lamination frame, and based on the movement formed by the receiving unit, the lamination frame is assisted to keep the lamination frame in dynamic balance and flip upward and toward the end where the hooking unit is located, so that the hooking unit takes the lamination frame upright;

[0009] The frame transfer device comprises a transfer frame, a transfer tool, a flip unit, a buffer unit, and a load-sharing unit, wherein the transfer tool is connected to the laminate frame from the laminate frame assembly line, and the flip unit is used to drive the transferred laminate frame to flip around the vertical direction so that the laminate frame stands upright and the assembly direction faces the feed end; the buffer unit can connect the reversing laminate frame from the transfer tool and keep it relatively parallel and side by side at intervals and buffer it in the buffer station, wherein each time a laminate frame is added to the buffer station, each laminate frame moves to fill the position, and is transferred from the output end by the load-sharing unit;

[0010] The framing device includes a framing station and a loading unit, wherein the framing station has a conveying component, the loading unit includes a docking component that is connected from the load-sharing unit and keeps the lamination frame assembly direction unchanged, a frame turning component that drives the docking component to flip horizontally so that the lamination frame assembly direction is downward, and a framing component that clamps the lamination frame from the docking component and keeps the assembly direction downward and is aligned with the photovoltaic component to be laminated for assembly.

[0011] According to a specific implementation and preferred aspect of the present invention, the receiving unit includes a positioning component, a top frame component and a receiving component, wherein the positioning component is used for positioning the laminated photovoltaic component; the top frame component keeps the laminate frame detached from the laminated photovoltaic component with the assembly direction facing downward and lifts it upward; the receiving component is connected and supported by the top frame component. Here, (1) the position of the laminated photovoltaic component is calibrated based on the positioning component and positioning is formed at the same time; (2) based on the positioning of the component and the shearing of the top frame, the laminated frame is separated from the laminated photovoltaic component; (3) based on the connection and support of the receiving component, the laminated frame is completely separated from the laminated photovoltaic component at the bottom to avoid accidental interference between the two due to frame removal. At the same time, based on the support, the probability of accidental falling of the laminated frame is avoided. In addition, not only the friction between the laminated frame and the support part is reduced, but also the phenomenon of the hook being stuck to the laminated frame or being unhooked is avoided.

[0012] Preferably, the positioning assembly comprises an alignment calibration module based on the framing station, and a plurality of positioning suction cup groups for adsorbing and positioning the laminated photovoltaic assembly from the bottom surface, wherein the calibrated laminated photovoltaic assembly is positioned based on the positioning suction cup group.

[0013] In some specific embodiments, there are four corresponding positioning suction cup groups, and they adsorb or disengage from the bottom surface of the laminated photovoltaic module based on vertical movement to form adsorption positioning.

[0014] Preferably, there are multiple top frame components, which are rectangularly distributed around the frame-taking station. Each top frame component includes a top support platform with a matching notch and a jacking actuator for driving the top support platform to move up and down. The matching notches of multiple top support platforms form a bearing area, and the lamination frame matches the bearing area and disengages from the laminated photovoltaic module during the jacking of the top support platform.

[0015] In some specific embodiments, it is arranged according to the frame edge length of the lamination frame. Generally, there are three top frame components for the long edges and two top frame components for the short edges.

[0016] Preferably, the receiving component includes receiving plates located on opposite sides of the frame-taking station and extending along the side edges of the corresponding side of the lamination frame, and receiving actuators for respectively driving the receiving plates to move to receive and assist the hook-taking unit to vertically take the frame.

[0017] In some specific embodiments, the receiving actuator includes a first power group for driving the receiving plate to move in the vertical direction and a second power group for driving the receiving plates to move relatively closer or farther away. The first power group is based on the hooking force of the hook-taking unit on the lamination frame so that the lamination frame maintains rotational contact with the hook-taking unit, and during synchronous descent, the receiving plate fits the auxiliary lamination frame to complete vertical frame-taking in a dynamically balanced state. The second power group is based on the approach of the two receiving plates and forms a motion cooperation with the top frame component to receive the lamination frame, and moves away from the two receiving plates to form a motion avoidance of the top frame component.

[0018] According to another specific implementation and preferred aspect of the present invention, the hook-taking unit includes a lifting seat, a hook component installed on the lifting seat, and a lifting actuator for driving the hook component to move up and down. The hook component hooks from the receiving unit based on the middle part of the side edge of the lamination frame, and the lamination frame maintains flipping contact with the hook component. When taking the frame, the lifting actuator and the receiving unit form a linkage with opposite motion directions so that the lamination frame maintains a dynamically balanced upward flip and approaches the lifting seat. The lamination frame is vertically inverted and hung on the hook component. Based on the dynamically balanced mode (prerequisite: the lifting actuator and the receiving unit form a linkage with opposite motion directions), the motion direction formed by the lamination frame as the height increases not only results in low frictional loss between the lamination frame and the receiving plate, but also avoids the phenomena of the hook getting stuck on the lamination frame or the hook disengaging. At the same time, the so-called dynamic balance means that during the lifting process of the lamination frame, the lifting force of the hook component on the lamination frame, the gravity of the lamination frame itself, and the force exerted by the receiving plate on the lamination frame constitute a dynamic balance.

[0019] Preferably, the hooking unit further includes buffer barriers located on opposite sides of the lifting seat, wherein the flipped lamination frame abuts against the buffer barriers and forms multi-point contact with the hook assembly to cooperate with the hook assembly to erect the picked lamination frame. Based on the buffer barriers, when the lamination frame is prevented from completely detaching from the receiving plate, it is possible to avoid the lamination frame from shaking relative to the hook assembly. Therefore, under the buffer barriers, not only does it assist the hook assembly to form multi-point contact to invert the lamination frame, but also it avoids hooking collisions and reduces the unhooking rate.

[0020] Preferably, the hook assembly includes a hook seat mounted on the lifting seat based on a slide rail, a horizontal lifting arm mounted on the hook seat, and a plurality of hooks slidably mounted on the horizontal lifting arm, wherein the plurality of hooks are arranged in an array on the horizontal lifting arm with the center of the horizontal lifting arm as a reference.

[0021] According to another specific implementation and preferred aspect of the present invention, the buffer unit includes a plurality of annular transmission chain groups arranged side by side, buffer hooks circumferentially arrayed around each annular transmission chain group, and a buffer power unit for driving the plurality of annular transmission chain groups to rotate synchronously. Among them, the plurality of buffer hooks arranged side by side and aligned form a buffer section at the lower part, a feeding end and a discharging end at both ends, and a buffer hook compensation section at the upper part. The buffer section forms a plurality of buffer workstations that are relatively parallel and arranged at intervals based on the buffer hooks. The cyclic compensation formed by the annular movement enables continuous feeding and discharging of the buffer section, meeting the requirements of flow operation.

[0022] Preferably, the load sharing unit includes a load sharing frame, a load sharing truss, and a load sharing hook connected to the discharging end. The load sharing hook is docked with the load sharing truss to move the lamination frame into the frame loading device based on the load sharing truss. The load sharing is achieved by using the method of hook docking and is sent to the corresponding frame loading center through the truss.

[0023] Alternatively, the load sharing unit has multiple groups of spaced-apart load sharing hooks that move along the transmission direction of the annular transmission chain group, and a plurality of lamination frames are arranged side by side on each load sharing hook. The number of frame loading devices corresponds to the number of groups of load sharing hooks, and the lamination frames on the load sharing hooks respectively enter the corresponding frame loading devices to complete the synchronous load sharing of the plurality of lamination frames. Generally, there are two groups of load sharing hooks, that is, a load sharing unit simultaneously picks two lamination frames (one in front and one behind), and then simultaneously sends the two lamination frames to two frame loading devices for synchronous frame loading to increase the lamination frame return efficiency.

[0024] In addition, the connection component includes a connection frame and a first clamping component installed on the connection frame, wherein the first clamping component aligns and clamps the lamination frame. The frame loading component includes a second clamping component and an alignment component, wherein the second clamping component cooperates with the first clamping component to connect the lamination frame from the connection frame, and the alignment component adjusts the alignment of the lamination frame with the photovoltaic module to be laminated below and places it on the frame downward. Based on the connection of the two clamping components, the lamination frame with the assembly direction downward is moved to directly above the photovoltaic module to be laminated (the position of the photovoltaic module to be laminated needs to be calibrated first when loading the frame), and then the lamination frame is moved downward for alignment and frame loading.

[0025] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0026] In the existing lamination frame reflow operation process, since the reflow station needs to complete the alternating supply of the laminated photovoltaic components and the photovoltaic components to be framed, once the alternating supply error occurs, the lamination frame reflow will be disordered, and assembly line operation cannot be performed, which not only results in low efficiency of lamination frame reflow, but also has a large probability of reflow disorder; at the same time, in the frame taking method adopted, most of them use vacuum adsorption to provide adsorption force to adsorb the lamination frame, and then the lamination frame is lifted while being adsorbed. However, this method has a great safety hazard. Once the adsorption point falls off or shifts during movement, it is easy to cause the risk of accidental falling of the lamination frame. Therefore, the probability of damage to the photovoltaic components is high, etc. The present invention comprehensively designs the structure of the frame taking, frame moving and frame installation integrated machine for the lamination frame reflow of the photovoltaic component, and cleverly solves the various deficiencies of the existing structure. After adopting the integrated machine for framing, moving and installing the laminated frame for the reflow of the photovoltaic module, the laminated photovoltaic module is firstly transmitted to the framing station through the transmission assembly, and then the laminated photovoltaic module and the laminated frame are separated by forming a relative shearing up and down, and the laminated frame is lifted up and completely separated from the laminated photovoltaic module, and then the laminated frame is lifted up and supported from both sides by a docking method, and then the lifting power device and the receiving unit form a linkage with opposite movement directions so that the laminated frame maintains dynamic balance and flips upward and approaches the lifting seat, and the laminated frame is upright and hung upside down on the hook assembly to complete the framing; secondly, the taken laminated frame is transmitted to the frame moving transfer device through the transmission path, and the laminated frame is docked by the transfer tool and the assembly direction of the laminated frame is adjusted based on the movement of the transfer tool and the flipping direction around the vertical direction, and then the laminated frame is cached to the cache station based on the alignment of the cache unit and the transfer tool and transmitted to the output end. , and it is transferred by the load-sharing unit at the same time; finally, the loaded laminate frame enters the framing center with the assembly direction unchanged, and the laminate frame is first clamped by the docking component, and then turned over to make the assembly direction of the laminate frame face downward, and the framing is completed based on the alignment and movement of the framing component. Therefore, on the one hand, the present invention is based on the assembly line operation formed by framing, moving and framing, and the incoming supply of laminate components or components to be laminated, framing and framing are completely independent. Therefore, it not only reduces the probability of confusion in each process, but also greatly increases the efficiency of lamination frame reflow based on cache assistance; on the other hand, when framing, based on the dynamic balance formed by the linkage with opposite movement directions formed by the lifting power device and the receiving unit, not only the friction loss between the laminate frame and the receiving plate is low, but also the phenomenon of the hook jamming the laminate frame or accidentally unhooking is avoided. At the same time, the layout is compact, and the framing can be completed in a smaller space. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] As Figures 1 to 14 shown, the frame-taking, frame-transferring, and frame-installing integrated machine for the lamination frame reflux of the photovoltaic module of this embodiment includes a frame-taking device ①, a frame-transferring and intermediate device ②, and a frame-installing device ③, wherein the lamination frame K is erected on the photovoltaic module G with the assembly notch facing downwards.

[0052] Specifically, refer to Figures 2 to 5The frame removing device ① includes a frame removing station 1, a hooking unit 2, and a receiving unit 3, wherein the frame removing station 1 has a transmission component; the receiving unit 3 can lift the lamination frame upward and detach it from the laminated photovoltaic component; the hooking unit 2 is located at one end of the transmission component, keeps the hooking center aligned with the center of a long side or a short side of the lamination frame, and based on the movement formed by the receiving unit 3, the lamination frame is assisted to keep the lamination frame in dynamic balance and flip it upward and toward the end where the hooking unit 2 is located, so that the hooking unit 2 takes the lamination frame upright.

[0053] The receiving unit 3 includes a positioning component 30, a top frame component 31 and a receiving component 32, wherein the positioning component 30 is used for positioning the laminated photovoltaic component; the top frame component 31 keeps the laminated frame detached from the laminated photovoltaic component with the assembly direction facing downward and lifts it upward; the receiving component 32 is connected and supported from the top frame component 31. Here, (1) the position of the laminated photovoltaic component is calibrated based on the positioning component and positioning is formed at the same time; (2) based on the positioning of the component and the shearing of the top frame, the laminated frame is separated from the laminated photovoltaic component; (3) based on the connection and support of the receiving component, the laminated frame is completely separated from the laminated photovoltaic component at the bottom to avoid accidental interference between the two due to frame removal. At the same time, based on the support, the probability of accidental falling of the laminated frame is avoided. In addition, not only the friction between the laminated frame and the support part is reduced, but also the phenomenon of the hook being stuck to the laminated frame or being unhooked is avoided.

[0054] In some specific embodiments, the positioning assembly 30 includes an alignment calibration module 300 based on the framing station, and a plurality of positioning suction cup groups 301 for adsorbing and positioning the laminated photovoltaic assembly from the bottom surface, wherein the calibrated laminated photovoltaic assembly is positioned based on the positioning suction cup group 301. In this example, there are four corresponding positioning suction cup groups 301, and the bottom surface of the laminated photovoltaic assembly is adsorbed or detached based on the up and down movement to form adsorption positioning. There are multiple top frame assemblies 31, and they are distributed in a rectangular shape around the framing station, wherein each top frame assembly 31 includes a top support platform 310 with matching notches, and a lifting power device 311 that drives the top support platform 310 up and down, and the matching notches of the multiple top support platforms 310 form a bearing area, and the laminated frame matches the bearing area, and is separated from the laminated photovoltaic assembly during the lifting of the top support platform 310. The layout is based on the frame length of the laminated frame. Generally, there are three top frame assemblies for the long frame and two top frame assemblies for the short frame. The receiving assembly 32 includes a receiving plate 320 located on opposite sides of the frame taking station and extending along the side edges of the corresponding side laminating frame, and a receiving power device 321 that drives the receiving plate 320 to move to receive and assist the hooking unit 2 to erect the frame, wherein the receiving power device 321 includes a first power group d1 that drives the receiving plate 320 to move in the up and down directions, and a second power group d2 that drives the receiving plate 320 to move relatively close to or away from the receiving plate 320, wherein the first power group d1 is based on the hooking force of the hooking unit 2 on the laminating frame so that the laminating frame maintains rotational contact with the hooking unit 2, and during the synchronous descent, the receiving plate 320 fits the auxiliary laminating frame in a dynamic equilibrium state to complete the erection of the frame; the second power group d2 is based on the approach of the two receiving plates 320 and forms a motion cooperation with the top frame assembly 32 to receive the laminating frame, and the distance of the two receiving plates 320 to form a motion avoidance of the top frame assembly 31.

[0055] The hooking unit 2 includes a lifting seat 20, a hook assembly 21 mounted on the lifting seat 20, a lifting power unit 22 for driving the hook assembly 21 to move up and down, and buffer blocking members 23 located on opposite sides of the lifting seat 20. The hook assembly 21 hooks from the bearing plate 320 with the midpoint of the side of the laminated frame as a reference, and the laminated frame is in flipping contact with the hook assembly 21. When taking the frame, the lifting power unit 22 and the bearing plate 320 form a linkage with opposite movement directions so that the laminated frame keeps flipping upward in dynamic balance and approaches the lifting seat 20. At the same time, based on the flipped laminated frame abutting against the buffer blocking members 23 and the multi-point contact formed by the hook assembly 21, the hook assembly cooperates to erect the taken laminated frame. Based on the dynamic balance mode (the precondition is that the lifting power unit and the bearing unit form a linkage with opposite movement directions), as the height increases, the movement direction formed by the laminated frame not only results in low frictional loss between the laminated frame and the bearing plate, but also avoids the phenomena of the hook jamming the laminated frame or unhooking. At the same time, the so-called dynamic balance means that during the lifting process of the laminated frame, the lifting force of the hook assembly on the laminated frame, the gravity of the laminated frame itself, and the acting force of the bearing plate on the laminated frame constitute a dynamic balance. Based on the buffer blocking members, when the laminated frame completely detaches from the bearing plate, it is avoided that the laminated frame shakes relative to the hook assembly. Therefore, under the buffer blocking members, it not only assists the hook assembly to form multi-point contact to invert the laminated frame, but also avoids hooking collisions and reduces the unhooking rate.

[0056] Specifically, the lifting seat 20 is located at one end of the transmission assembly. The hook assembly 21 includes a hook seat 210 mounted on the lifting seat 20 based on a slide rail h, a horizontal lifting arm 211 mounted on the hook seat 210, and a plurality of hooks 212 slidably mounted on the horizontal lifting arm 211. The plurality of hooks 212 are arranged in an array on the horizontal lifting arm 211 with the center of the horizontal lifting arm 211 as a reference. The lifting power unit 22 includes a ring transmission belt group 220. There are two ring transmission belt groups 220 and two slide rails h. The hook seats 210 are respectively slidably connected to the two slide rails h. At the same time, the hook seats 210 are fixedly mounted on the ring transmission belt group 220, and the up and down movement of the hook seats 210 is realized based on the synchronous movement of the two ring transmission belt groups 220. The buffer blocking member 23 includes a horizontally arranged elastic stop rod 230. The elastic stop rod 230 can be adjusted along its own length direction. At the same time, the elastic stop rod 230 is also adjusted by a horizontally arranged telescopic cylinder (that is, driving the elastic stop rod 230 to move relatively closer or farther away to meet the need of not requiring support).

[0057] See Figures 6 to 10, the frame transfer and buffer device ② includes a transfer rack 4, a transfer tool 5, a flipping unit M, a buffer unit 7, and a load sharing unit 8. The transfer tool 5 picks up the laminated frame from the lamination frame assembly line. The flipping unit M is used to drive the loaded laminated frame to rotate and change direction around the vertical direction so that the laminated frame stands upright and the assembly direction faces the feeding end. The buffer unit 7 can pick up the turned laminated frame from the transfer tool 5 and keep it cached in parallel and side-by-side intervals at the buffer station. For each additional laminated frame at the buffer station, each laminated frame moves to fill the position, and the load sharing unit 8 picks up the frames from the output end.

[0058] Specifically, the transfer rack 4 is a conventional frame. The transfer tool 5 can move along the length direction of the frame. The transfer tool 5 includes a hook member 50 and a positioning and adjusting member 51. The hook member 50 can move relative to the transfer rack 4 along the length and width directions to pick up the laminated frame. At the same time, the positioning and adjusting member 51 adjusts the position of the laminated frame in the hook member 50 from the relative two sides inside to align the center of the hook member 50 with the middle of the hanging edge of the laminated frame.

[0059] The buffer unit 6 includes a plurality of annular transmission chain groups 60 arranged side by side, buffer hooks 61 circumferentially arrayed around each annular transmission chain group 60, and a buffer power unit 62 that drives the plurality of annular transmission chain groups to rotate synchronously. Among them, the plurality of buffer hooks 61 arranged side by side and aligned form a buffer section at the lower part, a feeding end and a discharging end at both ends, and a buffer hook filling section at the upper part. The buffer section forms a plurality of buffer stations that are relatively parallel and spaced side by side based on the buffer hooks. The cyclic filling achieved by the circular motion enables continuous feeding and discharging of the buffer section to meet the requirements of flow operation. At the same time, in this example, there are two groups of annular transmission chain groups 60, which are arranged left and right. Two aligned buffer hooks 61 in the buffer section form a buffer station. The laminated frames are aligned and hung on each buffer station, and they are filled in position as they are transferred forward.

[0060] The load sharing unit 7 includes a load sharing rack 70, a load sharing truss 71, and a load sharing hook 72 connected to the discharging end. The load sharing hook 72 is docked with the load sharing truss 71 to move the laminated frame into the frame loading device ③ based on the load sharing truss 71. The load sharing is achieved by means of hook docking and sent to the corresponding frame loading center through the truss. In this example, the load sharing unit 7 has multiple groups of load sharing hooks 72 that are spaced apart and move along the transmission direction of the annular transmission chain group. Multiple laminated frames are arranged side by side on each load sharing hook 72. The frame loading devices ③ correspond to the number of groups of load sharing hooks 72, and the laminated frames on the load sharing hooks 72 enter the corresponding frame loading devices respectively to complete the synchronous load sharing of multiple laminated frames. Generally, there are two groups of load sharing hooks, that is, one load sharing unit picks up two laminated frames (one in front and one behind) at the same time, and then sends the two laminated frames to two frame loading devices for synchronous frame loading at the same time, one to the left and one to the right, to increase the return efficiency of the laminated frames.

[0061] Combination Figures 11 to 14 As shown, the framing device ③ includes a framing station 8 and a loading unit 9, wherein the framing station 8 has a conveying assembly, and the loading unit 9 includes a docking assembly 90 which is connected from the load-sharing unit 7 and keeps the lamination frame assembly orientation unchanged, a frame turning assembly 91 which drives the docking assembly 90 to flip horizontally so that the lamination frame assembly orientation is downward, and a framing assembly 92 which clamps the lamination frame from the docking assembly 90 and keeps the assembly orientation downward and is aligned with the photovoltaic assembly to be laminated for assembly.

[0062] The docking assembly 90 includes a docking frame 900, a first clamping component 901 installed on the docking frame 900, and a correction component 902, wherein the correction component 902 is first used to adjust and correct the centering, and then the first clamping component 901 is used to correct and clamp the lamination frame. The frame turning assembly 91 is composed of a conventional flip axis and a flip motor. The framing assembly 92 includes a second clamping component 920 and an alignment component 921, wherein the second clamping component 920 cooperates with the first clamping component 901 to dock the lamination frame from the docking frame 900, and the alignment component 921 adjusts the lamination frame and the photovoltaic assembly to be laminated below and mounts the frame downward. Based on the docking of the two clamping components, the lamination frame with the assembly direction facing downward is moved to the top of the photovoltaic assembly to be laminated (position calibration is required before framing the photovoltaic assembly to be laminated), and then the lamination frame is moved down for alignment framing.

[0063] In summary, the implementation process of this embodiment includes the following steps:

[0064] S1. Unframing of laminated photovoltaic modules

[0065] The laminated photovoltaic module is transferred to the frame removal station through the transmission assembly, and then the laminated photovoltaic module and the laminated frame are separated by forming a relative shearing up and down, and the laminated frame is lifted up and completely separated from the laminated photovoltaic module, and then the laminated frame is lifted up and supported from both sides by a docking method, and then the lifting power device and the receiving unit form a linkage in the opposite direction of movement so that the laminated frame maintains dynamic balance and flips upward and approaches the lifting seat, and the laminated frame is hung upright on the hook assembly to complete the frame removal;

[0066] S2, transfer and cache of laminated frame

[0067] The taken laminated frame is transferred to the frame transfer device through the transfer path, and the laminated frame is docked by the transfer tool, and the assembly direction of the laminated frame is adjusted to the feed end based on the movement of the transfer tool and the flipping direction around the vertical direction, and then the laminated frame is cached to the cache station based on the alignment of the cache unit and the transfer tool and transmitted to the output end, and at the same time, the laminated frame is transferred from the discharge end by the load-sharing unit;

[0068] S3. Lamination frame installation of photovoltaic modules to be laminated

[0069] The loaded laminate frame enters the framing center while maintaining the assembly direction unchanged, and is first clamped by the connecting component and then turned over to make the assembly direction of the laminate frame face downward, while the framing is completed based on the alignment and movement of the framing component.

[0070] Furthermore, in step S1, a buffer barrier is used for support and blocking, so that the laminate frame fits the buffer barrier from the bottom, and based on the multi-point contact formed by the buffer barrier and in cooperation with the hook of the hook assembly, the laminate frame is hung upside down on the hook assembly. In step S2, a circular transmission method is used for the transfer of the laminate frame, and the two ends of the circular transmission method constitute the receiving end and the output end, the lower section of the circular transmission method constitutes the buffer section, and the upper section of the circular transmission method constitutes the circular filling section. At the same time, during the transmission of the transfer tool, the laminate frame is aligned with the center of the transfer tool from the middle by the internal support correction method, and then the laminate frame is sent to the hook of the buffer section by the receiving and guiding of the end. Multiple laminate frames are arranged side by side and evenly spaced on the hook of the buffer section, and then the hook gradually sends the frame forward to supply and fill the laminate frame. In step S3, the photovoltaic components to be laminated on the conveying assembly are first calibrated, and then the lamination frame is calibrated on the docking assembly and then horizontally flipped. Based on the docking of the clamping parts, the lamination frame is moved to the top of the photovoltaic components to be laminated, and then the lamination frame is lowered to be assembled on the photovoltaic components to be laminated to complete the reflow of the lamination frame.

[0071] In summary, this embodiment has the following advantages:

[0072] 1) Based on the assembly line operation formed by frame removal, frame transfer and frame installation, and the incoming supply of laminated components or components to be laminated, frame removal and frame installation are completely independent. Therefore, it not only reduces the probability of confusion in each process, but also greatly increases the efficiency of lamination frame reflow based on cache assistance;

[0073] 2) When removing the frame, the dynamic balance formed by the linkage between the lifting power device and the receiving unit in opposite directions (the so-called dynamic balance means that during the lifting process of the laminate frame, the lifting force of the hook assembly on the laminate frame, the gravity of the laminate frame itself and the force of the receiving plate on the laminate frame constitute a dynamic balance), which not only reduces the friction loss between the laminate frame and the receiving plate, but also avoids the phenomenon of the hook being stuck in the laminate frame or accidentally unhooking. At the same time, the layout is compact and the frame can be removed in a small space. In addition, the laminated photovoltaic module position is calibrated based on the positioning component, and positioning is formed at the same time; based on the positioning of the module and the shearing of the top frame, Separate the laminated frame from the laminated photovoltaic assembly; based on the connection and bearing of the receiving assembly, completely separate the laminated frame from the laminated photovoltaic assembly at the bottom to avoid accidental interference between the two due to frame removal. At the same time, based on the bearing, avoid the probability of accidental falling of the laminated frame, which not only reduces the friction between the laminated frame and the bearing part, but also avoids the phenomenon of the hook being stuck or unhooked; based on the buffer barrier to avoid the laminated frame completely detaching from the receiving plate, causing the laminated frame to shake relative to the hook assembly. Therefore, under the buffer barrier, not only does the auxiliary hook assembly form multi-point contact to invert the laminated frame, but also avoids hook collision to reduce the unhooking rate;

[0074] 3) In the transfer buffer, the circular filling formed by the circular motion is used to realize the continuous feeding and discharging of the buffer section to meet the needs of the assembly line operation. At the same time, based on the adjustment of the circular motion and the alignment, the laminating frames are kept fed in the same direction and side by side. In addition, the load sharing is realized by the hook docking method, and the load is sent to the corresponding frame center through the truss. Generally, there are two groups of loading hooks, that is, one loading unit takes two laminating frames at the same time (one in front and one behind), and then sends the two laminating frames to two frame devices at the same time, one on the left and one on the right, for synchronous frame loading, so as to increase the laminating frame reflux efficiency;

[0075] 4) During the framing process, based on the connection of the two clamping parts, the laminating frame with the assembly direction facing downward is moved to just above the photovoltaic module to be laminated (position calibration is required before framing the photovoltaic module to be laminated), and then the laminating frame is moved down for alignment framing.
