Abstract

The present invention relates to a photovoltaic module frame supply process, including the steps of: S1, layered material preparation; S2, frame bar unloading; S3, same-layer material placement. On the one hand, the present invention is based on the opening direction of the layered frame bars, the front-to-back distribution of the short length sides, and the equal angle bearing formed by the receiving groove, so that two groups of frame bars maintain symmetrical angles and directions to carry out one-time feeding of a single photovoltaic module frame, meet the requirements of gluing and assembly implementation of the frame bars under the premise of symmetry, and at the same time, through the guidance and deceleration formed by the reference, avoid the probability of accidental rolling of the frame bars due to excessive unloading speed; on the other hand, multiple frame bars with the same direction are taken out in layers from the stacking area, so the probability of frame bar displacement and confusion is low, which is more conducive to the replenishment of the frame bars. In addition, for frame bars with different opening directions, based on a 180° rotation or flipping, the long and short frame bars are added to the corresponding channels to reduce the difficulty of manipulator replenishment, and the flipping process is simple and easy to implement.

Description

Technical Field

[0001] The invention belongs to the field of photovoltaics, and in particular relates to a frame supply process of a photovoltaic module. Background Art

[0002] Photovoltaic modules are made of crystalline silicon cells, tempered glass and packaging materials stacked in different orders, laminated to form a laminate and wrapped with a frame for protection. For a single photovoltaic module, the frame is generally made of four frames with the same cross-sectional shape, spliced ​​end to end, and combined with Figure 1 As shown, the cross section of each frame strip t includes a long side t1, a short side t2, a connecting side t3, and a layer separation side t4, wherein the long side t1 and the short side t2 are parallel and aligned on one side, the connecting side t3 is vertically arranged with the long side t1 and the short side t2 respectively, and the layer separation side t4 is located in the edge-wrapped area formed by the long side t1, the short side t2 and the connecting side t3. When the frame strip t is assembled, the long side t1 and the short side t2 are respectively attached to the front and back sides of the photovoltaic module, the connecting side t3 constitutes the outer end face of the photovoltaic module, and the layer separation side t4 connects the layer The pressed parts are stacked in layers; when stacked in layers, each layer has two groups of frame bars, one group of frame bars are arranged side by side with the connecting side t3 as the bottom surface, and the two adjacent frame bars t are attached from the long side t1 and the short side t2, and the opening of the edging area faces upward; the other group of frame bars are arranged side by side with the connecting side t3 as the bottom surface, and the two adjacent frame bars t are attached from the long side t1 and the short side t2, and the opening of the edging area faces downward. When the two groups of frame bars are stacked, the edging areas are matched up and down to form a plurality of spliced ​​rectangular bodies, and a plurality of rectangular bodies are arranged side by side in each layer, and the multiple layers are stacked in sequence.

[0003] However, photovoltaic modules are basically in the shape of a cuboid, and the frame bars formed not only have different lengths, but also have different assembly directions for the corresponding sides. Therefore, each photovoltaic module assembly requires four frame bars (two long and two short), and the two frame bars on the opposite sides need to be symmetrically arranged. This brings the following defects to the loading of the frame bars:

[0004] 1) Each time, two long frame strips are taken out from the frame strip stacking area for transfer and feeding, and then two short frame strips are taken out for transfer and feeding. Although it is feasible on the surface, the two long frame strips and the two short frame strips have the same direction. Since the frame strips themselves are long (generally about 3m), it is very difficult to change the direction after loading, which brings great inconvenience to the actual assembly. If the corresponding frame strips are taken out one by one, combined with the multi-axis flipping of the manipulator, although the orientation problem can be solved, the loading efficiency is too low to meet the assembly requirements. Therefore, it is impossible to implement the feeding of a set of frame strips while keeping the four frame strips at equal angles and the opposite sides symmetrical, that is, it cannot provide assistance for the subsequent gluing and assembly;

[0005] 2) Whether taking a single piece or two pieces at a time, the adjacent bars will shift during the taking process, causing confusion in the palletizing area and even the possibility of instantaneous collapse of the palletizing bars, greatly increasing the difficulty of loading the bars;

[0006] 3) Regarding the opening orientation problem of the hemming area, ordinary robots can deliver the frame strips to any position in any three-dimensional coordinate system. However, the long and short frame strips have different orientations due to stacking. Therefore, the frame strip supply procedure is very complicated and requires a larger or more loaded transfer robot to perform multiple flipping processes. 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 a new frame supply process for photovoltaic modules.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A photovoltaic module frame supply process, the frame includes a first frame bar, a second frame bar, a third frame bar, and a fourth frame bar which are sequentially arranged based on the outline of the photovoltaic module, wherein the first frame bar and the third frame bar are long frame bars and are butted up and down and stacked to form a long frame bar stack; the second frame bar and the fourth frame bar are short frame bars and are butted up and down and stacked to form a short frame bar stack, which includes the following steps:

[0010] S1. Layered material preparation

[0011] A) Four material preparation channels are formed, each of which has the same transmission direction, and from top to bottom, they are the first material preparation channel, the second material preparation channel, the third material preparation channel, and the fourth material preparation channel;

[0012] B) Using a transfer robot to pick up the upper layer of long frame strips with the same orientation from the long frame strips palletizing, and adjusting by a 180° flip once so that the connecting side of the long frame strips is located at the bottom side, and the long side and the short side are located at both sides of the connecting side, and then feeding them into the first preparation channel or the fourth channel; Using a transfer robot to pick up the upper layer of short frame strips with the same orientation from the short frame strips palletizing, and adjusting by a 180° flip once so that the connecting side of the long frame strips is located at the bottom side, and the long side and the short side are located at both sides of the connecting side, and then feeding them into the second preparation channel or the third channel, wherein the long and short sides of the frame strips in the first preparation channel and the second channel are arranged in the same front and back, both with the long side in front and the short side in the back; the long and short sides of the frame strips in the third preparation channel and the fourth channel are arranged in the same front and back, both with the short side in front and the long side in the back;

[0013] S2, frame strip unloading

[0014] A distributor capable of unloading frame strips one by one is provided at the outlet of each material preparation channel, and a receiving module is formed at the discharge end of each material preparation channel, wherein a receiving groove with an upward opening is formed at the top of each receiving module, and the receiving groove takes the front side as a reference, and the single frame strip separated by the distributor gradually slides forward along the reference and gradually detaches from the discharge end to be unloaded into the receiving groove; the frame strips placed in each receiving groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side, and the four frame strips are transferred to the receiving groove;

[0015] S3, loading materials on the same layer

[0016] The four receiving modules are sunk and the frame bars are placed on four loading modules spaced apart from each other and distributed side by side, wherein each loading module is provided with a loading groove similar to the receiving groove, and the four loading modules are formed from front to back into the first loading area, the second loading area, the third loading area and the fourth loading area, and the frame bars located in the first loading area and the second loading area are symmetrically arranged with the frame bars located in the third loading area and the fourth loading area.

[0017] Preferably, in step S1 B), the transfer robot has a multi-axis 360° rotation adjustment, wherein when the opening of the edging area of ​​the frame strip faces downward, the transfer robot acts on the top surface of the connecting side panel, and in the upside-down flipping, the opening faces upward so that the short side is in front and the long side is in the back, and then it is sent to the third channel or the fourth channel; when the opening of the edging area of ​​the frame strip faces upward, the transfer robot acts on the top surface of the layer separation edge, and changes direction around itself in the horizontal plane so that the long side is in front and the short side is in the back, and then it is sent to the first channel or the second channel.

[0018] According to a specific implementation and preferred aspect of the present invention, a transfer robot is used to clamp the upper long frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the long frame bars is located on the bottom side, and the long side and the short side are located on the front and back sides of the connecting side, and they are sent to the first material preparation channel; a transfer robot is used to clamp the upper short frame bars with the same direction from the short frame bar stack, and through flipping and adjusting, the connecting side of the short frame bars is located on the bottom side, and the long side and the short side are located on the front and back sides of the connecting side, and they are sent to the second material preparation channel; a transfer robot is used to clamp the upper short frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the short frame bars is located on the bottom side, and the short side and the long side are located on the front and back sides of the connecting side, and they are sent to the third material preparation channel; a transfer robot is used to clamp the upper long frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the long frame bars is located on the bottom side, and the short side and the long side are located on the front and back sides of the connecting side, and they are sent to the fourth material preparation channel.

[0019] In some specific embodiments, the first preparation channel, the second preparation channel, the third preparation channel, and the fourth preparation channel are replenished from top to bottom. Alternatively, the first preparation channel and the fourth preparation channel are replenished first, and then the second preparation channel and the third preparation channel are replenished. Alternatively, the second preparation channel and the third preparation channel are replenished first, and then the first preparation channel and the fourth preparation channel are replenished. In short, the order of replenishing is not limited.

[0020] According to another specific implementation and preferred aspect of the present invention, in step S1 A), each material preparation channel is composed of multiple annular conveyor belts that are arranged side by side and move synchronously, and the rear end of each material preparation channel is a feeding end, and the front end is a discharging end, wherein the feeding ends of the four material preparation channels are aligned vertically. Here, the alignment of the feeding ends facilitates the replenishment of the frame strips of the transfer robot.

[0021] Preferably, the discharge ends of the four material preparation channels are shortened inward layer by layer from top to bottom, the receiving modules are aligned with each discharge end, the placing modules are relatively staggered with the receiving modules, and the placing modules are located directly below each discharge end. The layout of the discharge end mainly provides a favorable operating space for unloading the frame strips one by one, that is, the frame strips can be transferred one by one or multiple frames through the height difference.

[0022] Furthermore, in step S2, two receiving groups are used, wherein the first receiving group is used for synchronous transfer of the first preparation channel and the second preparation channel, and the second receiving group is used for synchronous transfer of the third preparation channel and the fourth preparation channel. The two receiving groups transfer the frame strips with the same orientation and inclination angle respectively, which not only simplifies the parts required for transfer, but also transfers the frame strips unloaded to the receiving groove to the material placement groove with the angle unchanged by means of the staircase space.

[0023] According to another specific implementation and preferred aspect of the present invention, each receiving module group includes a material taking joint corresponding to the annular conveyor belt, and a receiving power device for driving the material taking joint to rise and fall, wherein the material taking joint includes an upper material taking module and a lower material taking module installed on the same base body and having a height difference, and the receiving grooves are respectively located on the upper material taking module and the lower material taking module, and the height difference between the upper material taking module and the lower material taking module of the first receiving group is equal to the height difference between the upper and lower first material preparation channels and the second material preparation channels; the height difference between the upper material taking module and the lower material taking module of the second receiving group is equal to the height difference between the upper and lower third material preparation channels and the fourth material preparation channels. That is, the synchronous unloading of the upper and lower two frame bars is achieved through the height difference.

[0024] Preferably, the material placement trough and the receiving trough are both V-shaped grooves with the opening facing upwards, and each material preparation channel is composed of multiple annular conveyor belts that are arranged side by side and move synchronously, wherein the V-shaped groove is composed of a first groove wall and a second groove wall distributed front and back, and when each frame strip is unloaded, the rear side of the V-shaped groove remains tangent to the discharge end of the annular conveyor belt. The tangential docking method is adopted to make the frame strip unloaded to the V-shaped groove more smoothly; especially for the frame strip with the long side in front and the short side in the back, it is difficult to realize the movement connection of the frame strip due to the center of gravity and inertial movement, and the present application is based on the tilt angle and the length of the support formed, and adopts a tangential method that does not affect the transmission, so that the frame strip is smoothly tilted and unloaded to the corresponding V-shaped groove.

[0025] In some specific embodiments, the V-shaped groove is in a right angle shape, so that a more stable fit support is formed with the right-angle transition frame. At the same time, the angle formed by the second groove wall and the horizontal plane is ∠1, where ∠1≤30°; in the positive projection along the length direction of the frame bar, the length of the connecting side of the frame bar is L1, the length of the second groove wall is L2, the length of the first groove wall is L3, and the length of the short side of the frame bar is L4, where L1>L2>L3≥L4. The motion connection formed in this way can best decelerate and unload the frame bar to avoid motion connection accidents, that is, to avoid the phenomenon of the frame bar rolling off from the V-shaped groove.

[0026] According to another specific implementation and preferred aspect of the present invention, a plurality of support modules are arranged at intervals at the outlet of each material preparation channel, wherein each support module comprises a mounting portion, a horizontal support portion, and a guide portion extending downward and forward from the front end of the horizontal support portion, wherein the top surface of the horizontal support portion is flush with the transmission surface of the corresponding material preparation channel, and the angle formed between the top surface of the guide portion and the top surface of the horizontal support portion is equal to the inclination angle of the connecting side after mounting. The horizontal support portion is used for support so that the frame strip is unloaded more smoothly, and at the same time, under the inclined guidance and the contact deceleration formed, the frame strip slowly falls into the receiving groove, avoiding the probability of the frame strip accidentally rolling down due to the excessive unloading speed.

[0027] In addition, the material distributor includes a first module and a second module located above the transmission path, wherein the first module and the second module are both capable of blocking and releasing the forward movement of the frame strips, and the frame strips are gradually prepared in a switching movement in which one of the first module and the second module is in a blocking state and the other is in a releasing state, wherein the frame strips arranged side by side on each preparation channel are transmitted forward, and are the 1st, 2nd, 3rd...Nth frames in sequence, and are first blocked by the blocking module, and the 1st, 2nd, 3rd...Nth frame strips slip relative to the endless conveyor belt, and then the clamping module moves to clamp the 2nd frame strip, and the clamping module causes the 2nd, 3rd...Nth frame strips to slip relative to the endless conveyor belt, and then the blocking module retracts to form a release, and the 1st frame strip is unloaded to the connected receiving groove along with the endless conveyor belt, and finally, the frame strips are automatically filled, and the above actions are repeated to complete the loading of the frame strips;

[0028] Preferably, in step S1 B), the frame strips fed into the transmission surface of each material preparation group are first aligned from the end by the end alignment module, and then transmitted forward from the channel alignment frame strip position formed by the grid calibration module to replenish the corresponding layer of frame strip preparation.

[0029] In some specific embodiments, each material preparation group includes a plurality of circular conveyor belts that are spaced apart, an end alignment module located at relatively outer sides of the plurality of circular conveyor belts, and a fence calibration module, wherein the end alignment module includes an alignment template located at both ends of the frame bar and capable of relative movement along the length direction of the frame bar, and an alignment driver corresponding one to one to the alignment template; the fence calibration module includes a fence template forming an input and output port, wherein the material divider is located at the front side of the output and output port.

[0030] Specifically, there are two annular transmission belts (of course it can be 3, 4, 5, 6 or more), and the gate template is arranged based on the length of the frame strip, and an entry port and an exit port are formed at both ends, that is, the ends of the frame strips entering between the two gate templates are in a relatively aligned (relatively corrected position) forward transmission; the alignment template is located at the entry port, and the frame strips are aligned during relative motion to avoid jamming or blocking of the frame strips entering the entry port due to incorrect position.

[0031] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0032] Based on the feeding of existing frame bars, no matter whether two bars are taken at a time or only one bar is taken each time, for the frame assembly of a single photovoltaic module, there are not only the distinction between long and short sides and up and down, but also the distinction between directions. Therefore, if the above method is used for feeding, not only the feeding efficiency cannot meet the assembly needs, but also due to the stacking characteristics of the frame bars themselves, adjacent frame bars may be shifted during the material taking process, resulting in confusion of the frame bars in the stacking area, and even the possibility of instantaneous collapse of the stacking frame bars, which greatly increases the difficulty of loading the frame bars; in addition, with regard to the opening direction problem of the edging area, ordinary manipulators can deliver the frame bars to any position in any three-dimensional coordinate system, but the long and short frame bars have different directions due to stacking, therefore, the frame bar supply procedure is very complicated, and a larger or heavier transfer manipulator is required to perform multiple flipping processes, etc. The present invention cleverly solves the various deficiencies of the existing structure by overall design of the frame supply process of the photovoltaic module. After adopting the frame supply process, first, four frame strips are prepared, wherein the four preparation channels are divided into two groups, one group is arranged side by side with the long side in front and the short side in the back, and the other group is arranged side by side with the short side in front and the long side in the back, the long frame strips are located in the first and fourth channels, the short frame strips are located in the second and third channels, and the long and short sides of the frame strips in the first and second channels are arranged in a consistent front-to-back layout, and the long and short sides of the frame strips in the third and fourth channels are arranged in a consistent front-to-back layout, and at the same time, the multi-axis motion flipping of the transfer manipulator is used to replenish the frame strips in the four preparation channels; then, the frame strips from each preparation group are gradually slid down along the reference one by one and gradually separated from the discharge end and unloaded to the receiving groove, wherein the frame strips placed in each receiving groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side; finally, the frame strips placed as the receiving groove descends are unloaded to the corresponding loading module, and the frame strips in the first loading group and the second loading group are symmetrically distributed to complete a single photovoltaic group The present invention adopts a layered preparation method for frame strips, and based on the opening orientation of the layered frame strips, the front-to-back distribution of the short sides, and the equal angle bearing formed by the receiving grooves, the two groups of frame strips are kept at symmetrical angles and orientations to feed a single photovoltaic module frame at one time, thereby meeting the gluing and assembly implementation requirements of the frame strips under the premise of symmetry, and at the same time, through the guidance and deceleration formed by the reference, the probability of accidental rolling of the frame strips due to excessive unloading speed is avoided; on the other hand, the method for taking the frame strips is also to take out multiple frame strips with the same orientation in layers from the stacking area. Therefore, the probability of frame strip displacement and confusion is low, which is more conducive to the replenishment of the frame strips. In addition, for frame strips with different opening orientations, based on a 180° horizontal rotation or 180° upside-down flipping, the long and short frame strips are supplemented to the corresponding channels to reduce the difficulty of the robot to replenish materials, and the flipping process is simple and easy to implement.

[0053] like Figures 2 to 13 As shown, the frame supply process of the photovoltaic module of this embodiment, the frame includes a first frame bar, a second frame bar, a third frame bar, and a fourth frame bar which are arranged in sequence based on the contour of the photovoltaic module, wherein the first frame bar and the third frame bar are long frame bars and are butt-jointed up and down and stacked to form a long frame bar stack M; the second frame bar and the fourth frame bar are short frame bars and are butt-jointed up and down and stacked to form a short frame bar stack N, that is, this application needs to feed from the long frame bar stack M and the short frame bar stack N, and supply a group of frames (that is, the first frame bar, the second frame bar, the third frame bar, and the fourth frame bar) in sequence.

[0054] Specifically, the frame supply equipment used in the frame supply process includes a layered material preparation unit ①, a material placement unit ②, and a material taking unit ③.

[0055] Specifically, the layered material preparation unit ① takes a single photovoltaic module frame as an example to supply long frame strips and short frame strips in layers. In this example, the layered material preparation unit ① includes four material preparation groups 1 arranged in layers from top to bottom, and a transfer robot 2 that takes out multiple frame strips t with the same orientation from the stacking area and delivers them to each material preparation group 1 using the connecting side t3 of the frame strip t as the mounting surface.

[0056] In some specific embodiments, each preparation group 1 has a feed end 1a, a discharge end 1b and a transmission surface 1c, and the edge area openings of each frame strip t are all stored on the transmission surface 1c from the mounting surface facing upward, and each transmission surface 1c transmits the frame strip t from back to front. The four preparation groups 1 are arranged in order from top to bottom according to long frame strips, short frame strips, short frame strips, and long frame strips, wherein the long frame strips and short frame strips at the top constitute the first preparation group 11, and the short frame strips and long frame strips at the bottom constitute the second preparation group 12. That is, the feeding system takes one photovoltaic module as the feeding base, in other words, four frame strips, two long and two short, need to be provided each time. In short, the mounted frame strips are mounted side by side with the long side in front and the short side in the back to form the first material preparation group 11, and the mounted frame strips are mounted side by side with the short side in front and the long side in the back to form the second material preparation group 12. That is to say, from top to bottom, the first material preparation group 11 is composed of long frame strips and short frame strips with the same orientation and the same front and back distribution of long and short sides; the second material preparation group 12 is composed of short frame strips and long frame strips with the same orientation and the same front and back distribution of long and short sides.

[0057] In this example, the feeding ends 1a of the four material preparation groups 1 are aligned; the discharging ends 1b of the four material preparation groups 1 are gradually protruding from bottom to top. At the same time, the transfer robot 2 is based on the premise of layered clamping frame strips, combined with a multi-axis motion method, to keep the connecting side t3 facing downward to supplement the frame strips t of each material preparation group 1.

[0058] Furthermore, each material preparation group 1 includes and is spaced apart from a plurality of annular conveyor belts 10, an end alignment module 13 and a fence calibration module 14 located at relatively outer sides of the plurality of annular conveyor belts 10, wherein the end alignment module 13 includes an alignment template 130 located at both ends of the frame bar and capable of relative movement along the length direction of the frame bar, and an alignment driver 131 corresponding one to one with the alignment template 130; the fence calibration module 14 includes a fence template 140 forming an entry and exit port, specifically, there are two annular conveyor belts 10 (of course, it can be 3, 4, 5, 6 or more), as for the fence template 140, it is arranged based on the length of the frame bar, and an entry and exit port are formed at both ends, that is, the end of the frame bar entering between the two fence templates 140 is in relative alignment (relative correction position) for forward transmission; the alignment template 130 is located at the entry and entry port, and aligns the frame bar during relative movement to avoid the phenomenon of material jamming or blocking due to incorrect position of the frame bar entering the entry and entry port.

[0059] In short, the four material preparation groups 1 form four material preparation channels, each of which has the same transmission direction, and from top to bottom, they are the first material preparation channel, the second material preparation channel, the third material preparation channel, and the fourth material preparation channel; each material preparation channel is composed of multiple annular conveyor belts that are arranged side by side and move synchronously, and the rear end of each material preparation channel is the feeding end, and the front end is the discharging end, wherein the feeding ends of the four material preparation channels are aligned up and down. Here, by aligning the feeding ends, it is convenient to supplement the frame strips of the transfer robot.

[0060] In some specific embodiments, the transfer robot has a multi-axis 360° rotation adjustment, wherein when the opening of the edging area of ​​the frame strip faces downward, the transfer robot acts on the top surface of the connecting side panel, and in the upside-down flipping, the opening faces upward so that the short side is in front and the long side is in the back, and then it is sent to the third channel or the fourth channel; when the opening of the edging area of ​​the frame strip faces upward, the transfer robot acts on the top surface of the layer separation edge, and changes direction around itself in the horizontal plane so that the long side is in front and the short side is in the back, and then it is sent to the first channel or the second channel. That is, a transfer robot is used to clamp the upper long frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the long frame bars is located on the bottom side, and the long side and the short side are located on the front and back sides of the connecting side, and they are sent to the first material preparation channel; a transfer robot is used to clamp the upper short frame bars with the same direction from the short frame bar stack, and through flipping and adjusting, the connecting side of the short frame bars is located on the bottom side, and the long side and the short side are located on the front and back sides of the connecting side, and they are sent to the second material preparation channel; a transfer robot is used to clamp the upper short frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the short frame bars is located on the bottom side, and the short side and the long side are located on the front and back sides of the connecting side, and they are sent to the third material preparation channel; a transfer robot is used to clamp the upper long frame bars with the same direction from the long frame bar stack, and through flipping and adjusting, the connecting side of the long frame bars is located on the bottom side, and the short side and the long side are located on the front and back sides of the connecting side, and they are sent to the fourth material preparation channel. At the same time, the first preparation channel, the second preparation channel, the third preparation channel, and the fourth preparation channel are replenished from top to bottom. Alternatively, the first preparation channel and the fourth preparation channel are replenished first, and then the second preparation channel and the third preparation channel are replenished. Alternatively, the second preparation channel and the third preparation channel are replenished first, and then the first preparation channel and the fourth preparation channel are replenished. In short, the order of replenishing is not limited.

[0061] The loading unit ② includes a loading rack 3 located below the discharge end 1b, and four loading modules 4 formed on the loading rack 3 and arranged side by side along the front-to-back direction, wherein each loading module 4 forms a loading trough 40 with an opening facing upward, and the four loading modules 4 are divided into a first loading group 41 and a second loading group 42 corresponding to the first preparation group 11 and the second preparation group 12, and the four loading troughs 40 correspond to the discharge end 1b of each preparation group 1 respectively.

[0062] The material taking unit ③ includes a divider 5 formed at the discharge end 1b of each preparation group 1 for dividing single frame strips, and a receiving module 6 located at the discharge end 1b of each preparation channel, wherein the top of each receiving module 6 forms a receiving groove 60 with an upward opening, and the receiving groove 60 is used as a reference. The single frame strip divided by the divider 5 gradually slides forward along the reference and gradually separates from the discharge end 1b and is unloaded to the receiving groove 60; the frame strips placed in each receiving groove 60 maintain an equal angle between the connecting side and the horizontal plane, and the long and short sides are respectively located at the upper and lower ends of the connecting side; at the same time, as the receiving groove 60 descends, the frame strips placed are unloaded to the corresponding material loading module 4, and the frame strips in the first material loading group 41 and the second material loading group 42 are symmetrically distributed.

[0063] In some specific embodiments, the distributor 5 includes a first module 51 and a second module 52 located above the transmission path, wherein the first module 51 and the second module 52 can both block and release the forward movement of the frame strip, and the frame strip is gradually prepared in the switching movement of one of the first module 51 and the second module 52 being in blocking and the other being in releasing. By switching the blocking and releasing positions and cooperating with the movement of the annular conveyor belt, the frame strips can be unloaded one by one into the connected receiving grooves. Specifically, the first module 51 and the second module 52 are arranged front and back, wherein the first module 51 includes blocking modules 510 located at both ends, and first telescopic cylinders 511 that respectively drive the blocking modules 510 to move along the length direction of the frame strip, wherein the two first telescopic cylinders 511 are telescopic so that the two blocking modules 510 form end blocking and release; the second module 52 includes clamping modules 520 located at both ends, and second telescopic cylinders 521 that respectively drive the clamping modules 520 to move along the length direction of the frame strip, wherein the two second telescopic cylinders 521 are telescopic so that the two clamping modules 520 form end clamping and release. In short, the side-by-side frame strips are transmitted forward, and in turn, the 1st, 2nd, 3rd...Nth frame strips are first blocked by the blocking module (with the long side t1 or the short side t2 of the front side of the frame strip as the positioning reference), and the 1st, 2nd, 3rd...Nth frame strips slip relative to the circular conveyor belt. Then, the clamping module 520 moves to clamp the layer separation edge t4 of the second frame strip t, and the clamping module 520 causes the 2nd, 3rd...Nth frame strips to slip relative to the circular conveyor belt. Then, the blocking module retracts to form a release, and the 1st frame strip is unloaded with the circular conveyor belt to the connected receiving groove. Finally, the frame strip automatically fills the position, and the above actions are repeated to complete the loading of the frame strips.

[0064] In some specific embodiments, the discharge ends of the four material preparation channels are shortened inward layer by layer from top to bottom, the receiving modules 6 are aligned with each discharge end, and the placing modules 4 are relatively offset from the receiving modules 6, and the placing modules 4 are located directly below each discharge end. The layout of the discharge end mainly provides a favorable operating space for unloading the frame strips one by one, that is, the frame bodies can be transferred one by one or multiple frames through the height difference. Each receiving module group 6 includes a material taking joint 6a corresponding to the annular conveyor belt, and a receiving power device 6b for driving the material taking joint 6a to rise and fall, wherein the material taking joint 6a includes an upper material taking module 61 and a lower material taking module 62 installed on the same base body and having a height difference, and the receiving groove 60 is respectively located on the upper material taking module 61 and the lower material taking module 62, and the height difference between the upper material taking module 61 and the lower material taking module 62 of the first receiving group is equal to the height difference between the upper and lower first material preparation channels and the second material preparation channels; the height difference between the upper material taking module 61 and the lower material taking module 62 of the second receiving group is equal to the height difference between the upper and lower third material preparation channels and the fourth material preparation channels. There are two corresponding receiving power devices 6b, and each receiving power device 6b is used to drive the corresponding base body to move up and down to perform a group of long and short frame strips with the same direction to be synchronously transferred. In short, the two receiving power devices 6b can be synchronous or sequential, depending on actual needs.

[0065] In addition, the material placement groove 40 and the receiving groove 60 are both V-shaped grooves with the opening facing upward. Based on the layout of the inclined V-shaped grooves, the frame strips are fed at the same inclination angle to facilitate the subsequent assembly implementation. The V-shaped groove is in a right angle, so that it can match the right-angle side corresponding to the frame strip, increase the stability and safety of the frame strip feeding, and at the same time, when taking the material, the rear side of the V-shaped groove remains tangent to the discharge end. Through the tangential matching positional relationship, it is more stable during the unloading of the frame strips, especially for the frame strips with the long side in front and the short side in the back. Due to the center of gravity and inertial movement, it is difficult to achieve the movement connection of the frame strips. The present application is based on the inclination angle and the length of the support formed, and adopts a tangent and transmission-free method to smoothly tilt and unload the frame strips to the corresponding V-shaped grooves.

[0066] In this example, in the orthographic projection along the length direction of the short side t2 of the frame strip, the V-shaped groove is composed of the first groove wall c1 and the second groove wall c2 distributed front and back, wherein the frame strip is attached to the second groove wall c2 from the connecting side and emerges from the second groove wall c2, and the frame strip is attached to the first groove wall c1 from the long side t1 or the short side t2. The V-shaped groove and the shape of the frame strip t are matched to facilitate the transfer of the frame strip t. The angle formed by the second groove wall c2 and the horizontal plane is ∠1, wherein ∠1≤30° (∠1=27° in this example); at the same time, in the orthographic projection along the length direction of the frame strip t, the length of the connecting side t3 of the frame strip is L1, the length of the second groove wall c2 is L2, the length of the first groove wall c1 is L3, and the length of the short side t2 of the frame strip is L4, wherein L1>L2>L3≥L4. This is to avoid the occurrence of movement connection accidents, that is, to avoid the phenomenon of the frame strip rolling down from the V-shaped groove.

[0067] In this example, based on the long length of the long frame strip t, a support module 8 that can be aligned with the corresponding annular conveyor belt 10 is provided at the position of the discharge end 1b, wherein the support module 8 and the annular conveyor belt 10 are arranged relatively spaced apart to implement the support of the long frame strip t. In some specific embodiments, the support module 8 includes a mounting portion 80, a horizontal support portion 81, and a guide portion 82 extending downward and forward from the front end of the horizontal support portion 81, wherein the angle formed between the top surface of the guide portion 82 and the top surface of the horizontal support portion 81 is equal to the inclination angle of the connecting side t3 after mounting. In this way, a guide is formed in the translation and oblique feeding to avoid the accidental rolling of the frame strip, and for the long frame strip, it can be more stably supported and transferred. Furthermore, the support modules 8 are located in the topmost and bottommost material preparation groups 1 (because the short sides are shorter, they are less likely to bend or deform), wherein each layer has two support modules 8, and the two support modules 8 are correspondingly distributed on the outsides of the two annular conveyor belts 10 on the same layer, and the two support modules 8 and the two annular conveyor belts 10 are spaced apart along the length direction of the long frame strips (equal spacing is optimal).

[0068] In addition, for the transfer robot 2 (purchased product), it includes a vacuum adsorption head 20, a base 21, and a plurality of adjustment arms 22 installed on the base 21, wherein the plurality of adjustment arms 22 are connected to each other by a rotating shaft, and are rotated and adjusted around the connecting rotating shaft. At the same time, the present application adds a rotation adjustment to the vacuum adsorption head 20 of the purchased transfer robot 2, that is, the vacuum adsorption head 20 can be rotated around its own axis. The advantage of this is that it facilitates the reversing and flipping operation of the frame strip.

[0069] In summary, the implementation steps of this embodiment are as follows:

[0070] S1. Layered material preparation

[0071] A) Four material preparation channels are formed, each of which has the same transmission direction, and from top to bottom, they are the first material preparation channel, the second material preparation channel, the third material preparation channel, and the fourth material preparation channel;

[0072] B) Using a transfer robot to pick up the upper layer of long frame strips with the same orientation from the long frame strips palletizing, and adjusting by a 180° flip once so that the connecting side of the long frame strips is located at the bottom side, and the long side and the short side are located at both sides of the connecting side, and then feeding them into the first preparation channel or the fourth channel; Using a transfer robot to pick up the upper layer of short frame strips with the same orientation from the short frame strips palletizing, and adjusting by a 180° flip once so that the connecting side of the long frame strips is located at the bottom side, and the long side and the short side are located at both sides of the connecting side, and then feeding them into the second preparation channel or the third channel, wherein the long and short sides of the frame strips in the first preparation channel and the second channel are arranged in the same front and back, both with the long side in front and the short side in the back; the long and short sides of the frame strips in the third preparation channel and the fourth channel are arranged in the same front and back, both with the short side in front and the long side in the back;

[0073] S2, frame strip unloading

[0074] A distributor capable of unloading frame strips one by one is provided at the outlet of each material preparation channel, and a receiving module is formed at the discharge end of each material preparation channel, wherein a receiving groove with an upward opening is formed at the top of each receiving module, and the receiving groove takes the front side as a reference, and the single frame strip separated by the distributor gradually slides forward along the reference and gradually detaches from the discharge end to be unloaded into the receiving groove; the frame strips placed in each receiving groove keep the angle formed by the connecting side and the horizontal plane equal, and the long and short sides are respectively located at the upper and lower ends of the connecting side, and the four frame strips are transferred to the receiving groove;

[0075] S3, loading materials on the same layer

[0076] The four receiving modules are sunk and the frame bars are placed on four loading modules spaced apart from each other and distributed side by side, wherein each loading module is provided with a loading groove similar to the receiving groove, and the four loading modules are formed from front to back into the first loading area, the second loading area, the third loading area and the fourth loading area, and the frame bars located in the first loading area and the second loading area are symmetrically arranged with the frame bars located in the third loading area and the fourth loading area.

[0077] Furthermore, in step S1 B), the frame strips fed into the transmission surface of each material preparation group are first aligned from the end by the end alignment module, and then transmitted forward from the channel alignment frame strip position formed by the grid calibration module to replenish the corresponding layer of frame strip preparation. In step S2, two receiving groups are used, wherein the first receiving group is used for synchronous transfer of the first material preparation channel and the second material preparation channel, and the second receiving group is used for synchronous transfer of the third material preparation channel and the fourth material preparation channel. There are two receiving groups to transfer the frame strips with the same orientation and inclination angle respectively, which not only simplifies the components required for transfer, but also uses the staircase space to transfer the frame strips unloaded to the receiving slot to the material placement slot with the angle unchanged.

[0078] In summary, the present invention adopts a layered preparation method for frame strips on the one hand, and based on the opening orientation of the layered frame strips, the front-to-back distribution of the short sides, and the equal angle bearing formed by the receiving grooves, the two groups of frame strips maintain symmetrical angles and orientations to carry out a single photovoltaic module frame feed, thereby meeting the gluing and assembly implementation requirements of the frame strips under the premise of symmetry, and at the same time, through the guidance and deceleration formed by the reference, the probability of accidental rolling of the frame strips due to excessive unloading speed is avoided; on the other hand, the method for taking the frame strips is also to take out multiple frame strips with the same orientation in layers from the stacking area. Therefore, the probability of frame strip displacement and confusion is low, which is more conducive to the replenishment of the frame strips. In addition, for frame strips with different opening orientations, based on a 180° horizontal rotation or 180° upside-down flip, the long and short frame strips are added to the corresponding channels to reduce the difficulty of the robot to add materials, and the flipping process is simple and easy to implement; the third aspect is based on the layout of the inclined V-groove, so that the frame strips maintain the same inclination angle for feeding, so as to facilitate the subsequent assembly implementation, and the V-groove is in a right angle shape, so that it can match the right-angle side corresponding to the frame strip, thereby increasing the stability and safety of the frame strip feeding. In addition, when taking materials, the tangential matching position relationship makes it more stable during the unloading of the frame strip, especially for the frame strips with the long side in front and the short side in the back. Due to the movement of the center of gravity and inertia, it is difficult to achieve the movement connection of the frame strips. However, the present application is based on the tilt angle and the length of the support formed, and adopts a tangent method that does not affect the transmission, so that the frame strips are smoothly tilted and unloaded to the corresponding V-groove; the fourth aspect is based on the layout of the feed end and the discharge end, which is not only convenient for adding frame strips to each layer of the preparation group, but also based on the difference in the length direction, it is convenient to implement the connection and transfer of the material taking joints in a smaller space. At the same time, two material taking joints are used and the height difference is used to synchronize the unloading of the frame strips by the first preparation group and the second preparation group. In addition, based on the switching of the blocking and release positions of the first module and the second module, and in coordination with the movement of the annular conveyor belt, The frame bars can be unloaded one by one into the connected receiving grooves; the fifth aspect is based on the alignment of the ends of the frame bars to avoid the phenomenon of jamming or blocking of the frame bars entering the inlet and outlet ports due to incorrect position. At the same time, the fence template is arranged based on the length of the frame bar, and the inlet and outlet ports are formed at both ends, that is, the ends of the frame bars entering between the two fence templates are in a relatively aligned (relatively corrected position) forward transmission; the sixth aspect is to support the frame bars through the horizontal support part to make the unloading of the frame bars smoother. At the same time, under the inclined guidance and the contact deceleration formed, the frame bars slowly fall into the receiving groove to avoid the probability of accidental rolling of the frame bars due to excessive unloading speed.

[0079] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
