Description

Technical Field

[0001] The present invention belongs to the technical field of lamination frame reflux, and specifically relates to a reflux frame-taking device for a photovoltaic module lamination frame, and also relates to a reflux frame-taking process for a photovoltaic module lamination frame. Background Art

[0002] The lamination frame of a photovoltaic module is a key component in the manufacturing process of a photovoltaic module, mainly used for fixing, supporting and sealing solar cells and encapsulation materials in the lamination process.

[0003] Currently, in order to improve the utilization rate of the lamination frame on the photovoltaic module, the lamination frame is usually taken out during the recycling of the photovoltaic module and assembled into another photovoltaic module. In order to separate the lamination frame from the module, a Chinese patent with the publication number CN114455310A discloses a frame-taking device, including: a support seat; an adsorption mechanism arranged on the support seat, and the adsorption mechanism can adsorb the photovoltaic module located on the support seat; a top frame mechanism, including at least two top frame components. In the X direction, at least one of the top frame components and at least another top frame component are respectively arranged at the middle parts of both ends of the support seat, and the execution end of the top frame mechanism can be lifted to jack up the lamination frame located on the support seat; and a clamping mechanism, including at least two clamping components. In the Y direction, at least one of the clamping components and at least another clamping component are respectively located at both ends of the support seat, and the clamping components can clamp the lamination frame located on the support seat and can drive the lamination frame to lift.

[0004] However, in the actual production process, the existing frame-taking device has the following technical defects:

[0005] 1. After being separated from the module, the lamination frame is lifted upward in a horizontal state and output to the next process. In the horizontal transmission space, the number of lamination frames that can be transmitted synchronously is limited, affecting the subsequent reflux transmission and frame-placement efficiency;

[0006] 2. During the separation and lifting of the lamination frame from the module, it is necessary to use the clamping components to clamp the lamination frame, which is likely to cause deformation and damage to the lamination frame, affecting recycling and reuse. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved reflux frame-taking device for a photovoltaic module lamination frame.

[0008] At the same time, the present invention also relates to a reflux frame-taking process for a photovoltaic module lamination frame.

[0009] To solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A reflow frame-taking device for a photovoltaic module lamination frame, which takes the lamination frame from a horizontally placed photovoltaic module, and includes a component positioning device, a receiving device, and a lifting device.

[0011] The receiving device includes a top frame assembly, receiving plates located on opposite sides of the lamination frame and offset from the top frame assembly, and a receiving actuator for driving the receiving plates to avoid or receive the movement of the lamination frame.

[0012] The lifting device includes a lifting carrier located at one end of the component transmission, a hook assembly installed on the lifting carrier, a lifting actuator for driving the hook assembly to move up and down, and a buffer assembly. The hook assembly hooks the lamination frame from the receiving plate based on the middle part of the side of the lamination frame. When taking the frame, the lifting actuator and the receiving actuator form a linkage with opposite movement directions, so that the lamination frame is turned upward while maintaining dynamic balance and approaches the buffer assembly. Among them, the lamination frame is vertically hung by cooperating with the hook assembly based on the multi-point contact formed with the hook assembly and the buffer assembly. The so-called dynamic balance in this application means that during the lifting process of the lamination frame, the lifting force of the hook assembly on the lamination frame, the gravity of the lamination frame itself, and the friction force between the lamination frame and the receiving plate form a dynamic balance.

[0013] According to a specific implementation and preferred aspect of the present invention, the hook assembly includes a plurality of hooks arranged side by side and spaced apart along the corresponding side of the lamination frame, and a hooking actuator for driving the plurality of hooks to extend or retract in a direction close to or away from the lamination frame. Among them, the plurality of hooks are divided into two groups and are symmetrically arranged about the center of the corresponding side of the lamination frame. Here, the smoothness of the hooking process is ensured.

[0014] Preferably, each hook includes a connection module, a first suspension rod extending downward from the connection module, a second suspension rod extending horizontally from the lower end of the first suspension rod towards the lamination frame, and a third suspension rod extending obliquely upward from the end of the second suspension rod away from the first suspension rod. When lifting, the corresponding side of the lamination frame is turned over in the space formed between the first suspension rod, the second suspension rod, and the third suspension rod.

[0015] Specifically, when the lamination frame is vertically hung on the hook, the corresponding side of the lamination frame is supported on the second suspension rod from the bottom, and the opposite sides are limited between the first suspension rod and the third suspension rod; and / or, the lower part of the first suspension rod is bent obliquely downward and then connected to the second suspension rod to form an obtuse angle; and / or, the upper end of the third suspension rod is bent obliquely upward towards the first suspension rod. Here, through the obtuse angle formed by the first suspension rod and the second suspension rod, the success rate of the side of the lifted lamination frame turning over in the hook is increased, avoiding jamming. At the same time, through the bending of the upper end of the third suspension rod, it is beneficial to form better limitation on the side of the lamination frame, ensuring that the lifted lamination frame remains upright for subsequent reflow transmission.

[0016] According to another specific implementation and preferred aspect of the present invention, the buffer assembly includes a stop bar disposed below the hook assembly and a buffer actuator for driving the stop bar to move towards or away from the lifting carrier. As the lamination frame is lifted, the stop bar abuts against the lamination frame and synchronously moves towards the lifting carrier. Herein, by keeping the stop bar in contact with the lamination frame and synchronously moving towards the lifting carrier, the lower part of the lamination frame is always buffered and supported during the flipping process of the lamination frame, further enhancing the stability of the movement of the lamination frame.

[0017] Preferably, as the lamination frame is lifted, the stop bar is arranged parallel to the horizontal side of the lamination frame; and / or, the stop bar and the buffer actuator form a buffer group, and there are two buffer groups which are symmetrically arranged.

[0018] According to another specific implementation and preferred aspect of the present invention, the lamination frame includes a long side and a short side. After the top frame, the receiving plate receives the short side of the lamination frame, and the hook assembly hooks the long side of the lamination frame and lifts it upward. Herein, the required flipping space is small, which is convenient for the equipment structure to be compact and saves space.

[0019] Preferably, the top frame assembly includes a long-side top frame component for jacking up the long side of the lamination frame and a short-side top frame component for jacking up the short side of the lamination frame. The jacking distance of the long-side top frame component is greater than that of the short-side top frame component; the long-side top frame component and the short-side top frame component each include a top frame module in a stepped shape matching the corresponding side of the lamination frame and a top frame actuator for driving the top frame module to move in the direction perpendicular to the corresponding side of the lamination frame and in the up and down directions. The width of the portion where each top frame module abuts against the lamination frame is smaller than the width of the corresponding side of the lamination frame. Herein, through the difference in the jacking distances of the long-side and short-side top frame components, after the lamination frame is jacked up to a preset distance, a space is formed between the lamination frame and the short-side top frame component for the receiving plate to be inserted for receiving; at the same time, by restricting the width of the top frame module, it is prevented that the top frame module in the top frame touches the component by mistake and causes damage to the component.

[0020] Preferably, the receiving plate is in a stepped shape matching the short side of the lamination frame; the receiving actuator drives the receiving plate to reciprocate along the long side direction of the lamination frame to avoid or receive the lamination frame.

[0021] Another technical solution of the present invention is a process for retrieving the lamination frame of a photovoltaic module, which uses the above-mentioned frame retrieving device, and the frame retrieving process includes the following steps:

[0022] S1. Horizontally place the component on the component positioning device and perform positioning;

[0023] S2. Use the top frame assembly to jack up the lamination frame upward so that the lamination frame is separated from the component, and the separated lamination frame is received by the receiving plates located on opposite sides of the lamination frame;

[0024] S3. Use the hook assembly to hook from the receiving plate with the middle part of the side of the lamination frame as the reference, drive the hook assembly to lift upward, and drive the receiving plate to move downward synchronously, so that the lamination frame is turned upward while maintaining dynamic balance and approaches the buffer assembly. The lamination frame is vertically hung by cooperating with the hook assembly based on the multi-point contact formed with the hook assembly and the buffer assembly, completing the frame picking.

[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 prior art, the lamination frame separated from the component is lifted upward while maintaining a horizontal state and output to the next process. In the horizontal transmission space, the number of lamination frames that can be transmitted synchronously is limited, affecting the subsequent return transmission and frame placing efficiency; during the separation and lifting of the lamination frame from the component, a clamping component is required to clamp the lamination frame, which easily causes deformation and damage of the lamination frame, affecting recycling and reuse. However, the present application conducts an overall design on the structure of the return frame picking device for the photovoltaic module lamination frame, ingeniously solving the deficiencies and defects of the prior art. After adopting this return frame picking device, after horizontally positioning the component, the lamination frame is lifted upward by the top frame assembly to separate the lamination frame from the component, and the lamination frame is received by the receiving plates on the opposite sides; then the hook assembly is used to hook from the receiving plate with the middle part of the side of the lamination frame as the reference, drive the hook assembly to lift upward, and drive the receiving plate to move downward synchronously, so that the lamination frame is turned upward while maintaining dynamic balance and approaches the buffer assembly. The lamination frame is vertically hung by cooperating with the hook assembly based on the multi-point contact formed with the hook assembly and the buffer assembly, completing the frame picking; therefore, compared with the prior art, on the one hand, based on the reverse linkage between the receiving plate and the hook assembly and the multi-point contact formed by the hook assembly and the buffer assembly on the lamination frame, the lamination frame can be stably hooked and the lamination frame can be turned and vertically hung while maintaining dynamic balance, effectively reducing the wear generated during frame picking and significantly improving the return quality of the lamination frame; on the other hand, based on the vertically hanging of the picked lamination frame on the hook assembly, the transmission space is saved, the lamination frame accommodation capacity of the return transmission line is greatly improved, ensuring stable return transmission and being beneficial to improving the subsequent frame placing efficiency.

[0042] As Figures 1 to 5 shown, the reflow frame-taking device of the photovoltaic module lamination frame of this embodiment includes a component positioning device 1, a receiving device 2, and a lifting device 3.

[0043] Specifically, the component positioning device 1 includes a component transmission line 10 with a framing station, a correction module 11 and a suction cup module 12 respectively arranged at the framing station, wherein the component is horizontally transmitted to the framing station along the component transmission line 10, and after the component is driven to be centered and positioned in the transmission direction by the correction module 11, the suction cup module 12 adsorbs the component to fix it. The component transmission line 10, the correction module 11 and the suction cup module 12 are prior arts, and will not be described here in detail, but they are clearly implementable. At the same time, the long side, short side, and thickness direction of the component are defined as the X, Y, and Z axes, respectively.

[0044] In this example, the receiving device 2 includes a top frame assembly 20, a receiving plate 21 located on opposite sides of the lamination frame K and offset from the top frame assembly 20, and a receiving power device 22 for driving the receiving plate 21 to avoid or receive the movement of the lamination frame K.

[0045] In some specific embodiments, the short side K0 and the long side K1 of the laminating frame K extend along the Y axis and the X axis respectively, and the top frame assembly 20 includes a short side top frame component 200 for lifting the short side K0 of the laminating frame, and a long side top frame component 201 for lifting the long side K1 of the laminating frame, wherein the lifting distance of the long side top frame component 201 is greater than the lifting distance of the short side top frame component 200; the long side top frame component 201 and the short side top frame component 200 each include a step-shaped top frame component 200 that matches the corresponding side of the laminating frame K. A plurality of top frame modules a0, a top frame power device a1 driving the top frame modules a0 to move in a direction perpendicular to the corresponding side of the laminating frame and in the up-down direction, the top frame power device a1 includes a horizontal transmission track a10 that is transmitted along the corresponding side of the laminating frame to drive each top frame module a0 to contact the corresponding side of the laminating frame in the corresponding direction, and a lifting and driving cylinder a11 correspondingly connected to each top frame module a0, wherein the width of the contact portion between each top frame module a0 and the laminating frame is smaller than the width of the corresponding side of the laminating frame. Here, by using the difference in the lifting distance of the long and short side top frame components, after the laminating frame is lifted to a preset distance, a space is formed between the laminating frame and the short side top frame components for the receiving plate to be inserted and received; at the same time, by limiting the width of the top frame module, it is prevented that the top frame module in the top frame accidentally touches the component and causes damage to the component. For the convenience of implementation, the horizontal transfer tracks a10 in the long side top frame component 201 and the short side top frame component 200 extend along the X-axis and the Y-axis respectively and are arranged to slide relatively in the X-axis direction, so that in the frame taking process, the top frame position of the long side top frame module a0 on the laminated frame can be synchronously adjusted through the top frame spacing of the top frame modules a0 on the short sides on both sides.

[0046] Meanwhile, the receiving plate 21 is in a stepped shape matching the short side K0 of the lamination frame; the receiving actuator 22 is composed of a lifting power cylinder and a lateral power cylinder. The lateral power cylinder drives the receiving plate 21 to reciprocate along the long side K1 direction (i.e., the X-axis direction) of the lamination frame to avoid or receive the lamination frame. That is, when the top frame assembly 20 jacks up the lamination frame, the receiving plate 21 moves away from the lamination frame along the X-axis direction to form an avoidance, and when the lamination frame rises to a preset height, the receiving plate 21 moves closer to the lamination frame along the X-axis direction; when the lifting device 3 lifts the long side of the lamination frame, the lifting power cylinder drives the receiving plate 21 to move downward. In this case, the required flipping space is small, which is convenient for the compact structure of the equipment and saves space.

[0047] In this example, the lifting device 3 includes a lifting carrier 30 located at one end of the component transmission, a hook assembly 31 installed on the lifting carrier 30, a lifting actuator 32 driving the hook assembly 31 to move up and down, and a buffer assembly 33. The hook assembly 31 hooks the lamination frame K from the receiving plate 21 with the middle part of the side (i.e., the long side K1) of the lamination frame as the reference. When taking the frame, the lifting actuator 32 and the receiving actuator 22 form a linkage with opposite movement directions, so that the lamination frame K is flipped upward while maintaining dynamic balance and approaches the buffer assembly 33. Among them, the lamination frame K is vertically hung by the hook assembly 31 based on the multi-point contact formed with the hook assembly 31 and the buffer assembly 33. The so-called dynamic balance in this application means that during the lifting process of the lamination frame, the lifting force of the hook assembly on the lamination frame, the gravity of the lamination frame itself, and the friction force between the lamination frame and the receiving plate form a dynamic balance.

[0048] In some specific embodiments, the hook assembly 31 includes two hooks 310 arranged side by side and spaced apart along the long side of the lamination frame, and a hooking actuator 311 connected to the lifting carrier 30 and driving the two hooks 310 to extend or retract in the direction of approaching or leaving the lamination frame K. Among them, the two hooks 310 are symmetrically arranged about the center of the long side K1 of the lamination frame. Here, the smoothness of the hooking process is ensured.

[0049] Each hook 310 includes a connection module b0, a first boom b1 extending downward from the self-connection module b0, a second boom b2 extending horizontally from the lower end of the first boom b1 towards the lamination frame, and a third boom b3 extending obliquely upward from the end of the second boom b2 away from the first boom b1. When lifting, the long side K1 of the lamination frame flips within the space formed among the first boom b1, the second boom b2, and the third boom b3. When the lamination frame is vertically hung on the hook 310, the long side K1 of the lamination frame is supported on the second boom b2 from the bottom, and the opposite sides are limited between the first boom b1 and the third boom b3; the lower part of the first boom b1 is bent obliquely downward and then connected to the second boom b2 to form an obtuse angle; the upper end of the third boom b3 is bent obliquely upward towards the direction close to the first boom b1. Herein, through the obtuse angle formed by the first boom and the second boom, the success rate of the side of the lifted lamination frame flipping within the hook is increased, avoiding jamming. At the same time, through the bending of the upper end of the third boom, it is beneficial to form better limitation on the side of the lamination frame, ensuring that the lifted lamination frame remains upright for subsequent return transmission.

[0050] The lifting actuator 32 includes a lifting guide rail 320 extending along the Z-axis direction and an endless transmission belt 321. The lifting carrier 30 is slidably connected to the lifting guide rail 320 and fixedly connected to the endless transmission belt 321.

[0051] The buffer assembly 33 includes a stop bar 330 disposed below the hook assembly 31 and a buffer actuator 331 for driving the stop bar 330 to move towards or away from the lifting carrier 30. The buffer actuator 331 employs a buffer cylinder that telescopically moves along the Y-axis direction. As the lamination frame K is lifted, the stop bar 330 abuts against the short sides K0 on both sides of the lamination frame and synchronously moves towards the direction close to the lifting carrier 30. Herein, by keeping the stop bar abutting against the lamination frame and synchronously moving towards the direction close to the lifting carrier, the lower part of the lamination frame is always kept under buffer support during the flipping process of the lamination frame, further enhancing the stability of the movement of the lamination frame.

[0052] In addition, as the lamination frame is lifted, the stop bar 330 is arranged parallel to the long side K1 of the lamination frame, and the stop bar 330 and the buffer actuator 331 in this embodiment form a buffer group. There are two buffer groups and they are symmetrically arranged.

[0053] Therefore, the return frame taking process of the photovoltaic module lamination frame in this embodiment includes the following steps:

[0054] S1. Horizontally place the component on the component positioning device and perform positioning;

[0055] S2. Use the top frame assembly to jack up the lamination frame upward so that the lamination frame is separated from the component, and the separated lamination frame is received by the receiving plates located on the opposite sides of the lamination frame;

[0056] S3. Use the hook assembly to hook from the receiving plate with the middle part of the side of the lamination frame as the reference, drive the hook assembly to lift upward, and drive the receiving plate to move downward synchronously, so that the lamination frame keeps dynamically balanced and turns upward and approaches the buffer assembly. The lamination frame is vertically hung in cooperation with the hook assembly based on the multi-point contact formed with the hook assembly and the buffer assembly to complete the frame taking.

[0057] In summary, after adopting this return frame taking device, after horizontally positioning the component, the lamination frame is lifted upward by the top frame assembly so that the lamination frame is separated from the component, and the lamination frame is received by the receiving plates on the opposite sides; then use the hook assembly to hook from the receiving plate with the middle part of the side of the lamination frame as the reference, drive the hook assembly to lift upward, and drive the receiving plate to move downward synchronously, so that the lamination frame keeps dynamically balanced and turns upward and approaches the buffer assembly. The lamination frame is vertically hung in cooperation with the hook assembly based on the multi-point contact formed with the hook assembly and the buffer assembly to complete the frame taking; therefore, compared with the prior art, on the one hand, based on the reverse linkage between the receiving plate and the hook assembly and the multi-point contact formed by the hook assembly and the buffer assembly on the lamination frame, the lamination frame can be stably hooked and the lamination frame can be turned and vertically hung under dynamic balance, effectively reducing the wear caused by frame taking and significantly improving the return quality of the lamination frame; on the other hand, based on the vertically hanging of the taken lamination frame on the hook assembly, the transmission space is saved, the lamination frame accommodation capacity of the return transmission line is greatly improved, the return transmission is ensured to be stable, and it is beneficial to improve the subsequent frame placing efficiency; on the third hand, through the obtuse angle formed by the first suspension rod and the second suspension rod, the success rate of the side of the lamination frame turning in the hook is improved, and jamming is avoided. At the same time, through the bending of the upper end of the third suspension rod, it is beneficial to form better limit on the side of the lamination frame to ensure that the lifted lamination frame remains upright for subsequent return transmission; on the fourth hand, by keeping the stop rod in contact with the lamination frame and moving synchronously towards the direction close to the lifting carrier, the lower part of the lamination frame is always buffered and supported during the turning process of the lamination frame, further enhancing the stability of the movement of the lamination frame; on the fifth hand, the required turning space is small, which is convenient for the equipment structure to be compact and saves space; on the sixth hand, through the difference in the jacking distances of the long-side and short-side top frame components, after the lamination frame is jacked up to a preset distance, a space is formed between the lamination frame and the short-side top frame component for the receiving plate to be inserted for receiving.

[0058] The above has made a detailed description of the present invention, aiming to enable those skilled in this field to understand the content of the present invention and implement it. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
