Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic frame production, and in particular to an automatic stacking device for photovoltaic frames. Background Art

[0002] Photovoltaic frames are important components of photovoltaic equipment. The existing production processes of photovoltaic frames include cutting, riveting and welding. Before welding, the photovoltaic frame is in a strip shape, with wedge blocks installed at both ends. In order to save space, one photovoltaic frame will be flipped and misaligned and pressed on the other photovoltaic frame. Figure 5 As shown, before this, a layer of paper will be placed between the two photovoltaic frames, which is a layer of photovoltaic frame to prevent the two photovoltaic frames from being damaged by friction. This process is the stacking process of the photovoltaic frames.

[0003] The existing palletizing equipment uses a small robotic arm to grab the photovoltaic frames, and can grab about 3-5 groups of frames at a time, while the existing packaging equipment has about 15-20 groups of frames per layer, resulting in the existing palletizing requiring the robotic arm to grab and flip about 4-6 times per layer. In addition, in the existing equipment, each conveying and flipping are carried out separately, that is, the palletizing is carried out after the conveying is completed and flipped by the flipping device, which is inefficient. In addition, stacking a single layer in multiple times will cause the paper between each group of frames to be discontinuous, so that the subsequent disassembly is very troublesome, which in turn affects the overall production efficiency of the photovoltaic frames.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Example: Reference Figure 1-Figure 6 A photovoltaic frame automatic stacking device comprises a frame 1 and a photovoltaic frame 6, characterized in that it also comprises a conveying mechanism, comprising a feeding conveyor belt 3 and a feeding synchronous belt 4 installed in the frame 1, the rotating shaft of the feeding conveyor belt 3 is connected to a first driving motor 301, the rotating shaft of the feeding synchronous belt 4 is connected to a second driving motor 401, a crossbeam 2 is provided at the bottom of the frame 1, the feeding conveyor belt 3 and the feeding synchronous belt 4 are both installed on the crossbeam 2, a length adjustment component 5 is installed on the crossbeam 2, the length adjustment component 5 comprises two first driving cylinders arranged on the crossbeam 2, and the output shafts of the two first driving cylinders are facing oppositely, and adjustment plates are installed on the output shafts of the two first driving cylinders, and the two adjustment plates are driven by the two first driving cylinders to approach each other to clamp the photovoltaic frame 6 on the feeding synchronous belt 4.

[0040] like Figure 1 and Figure 3 As shown, the processed photovoltaic frame 6 is conveyed to the loading synchronous belt 4 by the loading conveyor belt 3, wherein a limit plate and a counter are provided on the loading synchronous belt 4. By counting the photovoltaic frames 6 passing through, when the preset number is reached, the clamping and flipping process is started, and the limit plate is provided at one end of the loading synchronous belt 4 away from the loading conveyor belt 3 to prevent the photovoltaic frame 6 from falling off the loading synchronous belt 4.

[0041] In addition, to facilitate subsequent clamping, a length adjustment component 5 is arranged below the feeding synchronous belt 4, and two adjustment plates are used to clamp the two ends of the photovoltaic frame 6 passing through, so that the position of the photovoltaic frame 6 passing through here is aligned.

[0042] refer to Figure 10-Figure 14In order to facilitate grabbing and turning over, a truss gripper mechanism is provided in the equipment, which is used to grab the photovoltaic frame 6 on the loading synchronous belt 4 and turn it over, including a conveyor frame 17 slidably mounted on the frame 1, a first rack 21 is provided on the top wall of the frame 1, a transmission rod 19 is rotatably mounted on the conveyor frame 17, and first gears 20 adapted to the first rack 21 are fixedly mounted on both ends of the transmission rod 19, and a third driving motor 18 for driving the transmission rod 19 to rotate is provided on the conveyor frame 17, and a lifting frame 22 is slidably mounted up and down in the conveyor frame 17, and a second rack 24 is fixedly mounted on the outer wall of the side away from the two lifting frames 22, and a guide frame adapted to the lifting frame 22 is fixedly mounted on one side of the conveyor frame 17, and a fifth driving motor is provided on one side of the guide frame, and the output shaft of the fifth driving motor rotates and penetrates the outer wall of the guide frame, and a second gear adapted to the second rack 24 is fixedly mounted on the output shaft of the fifth driving motor, and a rotating frame 23 is rotatably mounted on the lifting frame 22, and the lifting frame A rotating motor 30 is provided on 22 for driving the rotating frame 23 to rotate 180 degrees. Two clamping frames 25 are slidably installed on the rotating frame 23. A bidirectional threaded rod 28 is rotatably installed on the inner side wall of the rotating frame 23. The bidirectional threaded rod 28 is provided with two sections of threads with the same length and opposite thread directions. Threaded holes are opened on the two clamping frames 25. The two clamping frames 25 are installed with the two sections of threads on the bidirectional threaded rod 28 in a one-to-one correspondence through the threaded holes. When the bidirectional threaded rod 28 rotates, the two clamping frames 25 approach each other or move away from each other. A fourth driving motor 29 for driving the bidirectional threaded rod 28 to rotate is provided on the rotating frame 23, a third driving cylinder is provided on the rotating frame 23, and a push plate 27 is fixedly installed on the output shaft of the third driving cylinder, and a limiting frame 26 is fixedly installed on the rotating frame 23. A second driving cylinder is provided on the two clamping frames 25, wherein a first clamping plate is fixedly installed on the output shaft of one of the second driving cylinders, and a second clamping plate is elastically installed on the output shaft of the other second driving cylinder.

[0043] After a preset number of photovoltaic frames 6 are reached on the above-mentioned synchronous feeding frame 4, the third driving motor 18 is used to drive the transmission rod 19 to rotate, thereby driving the two first gears 20 to rotate, and the second gear 20 is engaged with the first rack 21 at the top of the frame 1, so as to achieve the purpose of sliding the conveying frame 17 on the top of the frame 1. Figure 2 , Fig.10 and Fig.12 As shown, through the above-mentioned driving method, the conveying frame 17, the lifting frame 22 and the rotating frame 23 move to the top of the feeding synchronous belt 4. Fig.10 and Fig.11 Then, the fifth driving motor drives the second rack 24 to rotate, and the lifting frame 22 is driven to adjust the height by the same gear and rack transmission effect, thereby adjusting the height of the rotating frame 23, and the two clamping frames 25 follow the rotating frame 23 to descend to the position of the photovoltaic frame 6. Fig.10 and Fig.13 As shown, the aligned half-layer photovoltaic frame 6 is then clamped and lifted by two clamping frames 25. During the lifting process, the rotating frame 23 is driven by the rotating motor 30 to rotate to complete the flipping of the half-layer photovoltaic frame 6. The flipped half-layer photovoltaic frame 6 is lowered again by the lifting frame 22, and the clamping frame 25 is released to place the half-layer photovoltaic frame 6 on the other half-layer photovoltaic frame 6.

[0044] In the above process, the material turning, upward movement and position shifting are carried out synchronously, and at the same time, the photovoltaic frame 6 of the other half layer is also being stacked piece by piece, which saves a lot of time compared with the original stacking method and improves the efficiency of stacking.

[0045] The specific clamping method is that the bidirectional threaded rod 28 is driven to rotate by the fourth driving motor 29. When the bidirectional threaded rod 28 rotates, the two sections of thread thereon are respectively threadedly transmitted with the threaded holes on the two clamping frames 25, so as to adjust the distance between the two clamping frames 25. The two clamping frames 25 are driven to approach each other, that is, the two clamping frames 25 are respectively close to the two ends of the photovoltaic frame 6, and then the first clamping plate and the second clamping plate are respectively driven to approach the two ends of the photovoltaic frame 6 by the second driving cylinder on the two clamping frames 25, wherein the second clamping plate is elastically installed (the specific installation method is to connect through a spring), so that after clamping, the half-layer photovoltaic frame 6 will move a certain distance in the direction of the second clamping plate, and the specific moving distance can be controlled by the contraction length of the spring. In this way, the half-layer photovoltaic frame 6 is staggered in position with the other half-layer photovoltaic frame 6 on the lower loading synchronous belt 4, such as Figure 5 The stacking method of two photovoltaic frames 6 is shown.

[0046] refer to Figure 7-Figure 9The device is also provided with an upper corner paper coding mechanism, including two movable plates 7 arranged on both sides of the feeding synchronous belt 4, and first grippers 9 for grabbing paper strips are slidably installed on the two movable plates 7, and a plurality of second grippers 13 for conveying paper strips are provided on the movable plate 7. The upper corner paper coding mechanism also includes a first cylinder 15 slidably installed on the movable plate 7, and a paper feeding rack 14 is fixedly installed on the output shaft at the top of the first cylinder 15, and a plurality of second grippers 13 are fixedly installed on the paper feeding rack 14 at equal distances, and a second cylinder 16 is fixedly installed on the movable plate 7, and the output shaft of the second cylinder 16 is slidably connected to the paper feeding rack 14, a sixth driving motor is provided on the first gripper 9, and a third gear is fixedly installed on the output shaft of the sixth driving motor, and a third rack matched with the third gear is provided on the movable plate 7, and a first paper output roll 8 is rotatably installed on one side of the movable plate 7, and the first paper output roll is grabbed and pulled out by the first gripper 9. 8, a shearing assembly 10 is provided at the movable plate 7 near the first paper output roll 8, the shearing assembly 10 drives a scissors through a pneumatic part to cut the passing paper strip, and a third gripper is also provided at the shearing assembly 10, the gripper will clamp the paper output end of the first paper output roll 8, so that the first gripper 9 can extract the paper strip from the first paper output roll 8 again, a guide assembly for guiding the paper strip is fixedly installed on the movable plate 7, the guide assembly includes a roller group 11 rotatably installed on the movable plate 7, the roller group 11 includes a first roller 1101 and a second roller 1102, the guide assembly also includes a forming template 12 fixedly installed on the movable plate 7, the forming template 12 is provided with a forming hole 1201, a sliding frame 32 is provided at the bottom of the frame 1, and the sliding frame 32 is located on one side of the crossbeam 2, two second paper output rolls 31 are installed on the sliding frame 32, and a paper output roller 33 is installed on the sliding frame 32.

[0047] like Figure 7 and Figure 8 As shown, in order to prevent collision and friction between the upper and lower photovoltaic frames 6, a layer of paper strips will be placed between the two. The specific placement method is to clamp one end of the paper roll on the first paper output roll 8 through the first gripper 9, and drive the third gear and the third rack through the sixth drive motor to realize the sliding of the first gripper 9 on the movable plate 7, so as to pull the paper roll out of the first paper output roll 8. After being pulled to a preset length (the length is set according to the actual length of each layer of the photovoltaic frame 6), the paper strip is pulled out through the shearing component 10. The roll of paper is cut to obtain a paper strip, and then the first cylinder 15 and the second cylinder 16 are used to drive the paper feed rack 14 to rise and fall and translate respectively, first translate and start multiple second grippers 13 to clamp the paper strip, at this time the first gripper 9 releases the paper strip, and then the paper feed rack 14 moves up, so that the height of the paper strip is basically the same as the top height of the photovoltaic frame 6, and then the paper feed rack 14 is driven to translate again to send the paper strip to the photovoltaic frame 6, and at the same time control the second grippers 13 to release the paper strip, and the paper strip is placed on the top wall of the photovoltaic frame 6, and then the paper feed rack 14 returns along the original path.

[0048] It is worth noting that the clamping frame 25 is large in size and can clamp multiple photovoltaic frames 6 at the same time, so that there is only one whole paper strip on each layer. In the subsequent welding and other processes of the manufacturer, the coded photovoltaic frames 6 need to be disassembled. A whole paper strip is convenient for removal without problems such as residual paper scraps.

[0049] A guide assembly is provided at the first paper output roll 8 to guide and shape the paper roll. Figure 8 As shown, when the rolled paper passes through the roller assembly 11, it will be squeezed down and gradually become an inverted V shape under the shaping of the forming hole 1201 of the forming mold 12, the purpose of which is to make the paper strip more suitable for the shape of the overlap of the two photovoltaic frames.

[0050] It is worth noting that the first gripper 9, the second gripper 13 and the third gripper are all pneumatically driven for the purpose of clamping. This technology is existing technology and will not be described in detail.

[0051] In addition, a layer of paper needs to be placed between the layers, such as Fig.14 A sliding frame 32 is also provided at the placement area of ​​the photovoltaic frame 6, and a second paper roll 31 is provided on the sliding frame 32, and its working principle is the same as that of the first paper roll 8. White copy paper is provided on the paper roll 33. In addition to laying the roll paper, another layer of white copy paper is laid after each layer of the photovoltaic frame 6 is laid according to the needs, and the laying principle is also carried out by grabbing and cutting with a gripper.
