Description

Technical Field

[0001] This invention relates to the field of photovoltaic frame manufacturing technology, and more specifically to an automatic photovoltaic frame stacking device. Background Technology

[0002] Photovoltaic frames are a crucial component of photovoltaic (PV) devices. Current PV frame manufacturing processes include cutting, riveting, and welding. Before welding, the PV frame is strip-shaped, with wedges installed at both ends. To save space, one PV frame is flipped and offset onto another, such as... Figure 5 As shown, a layer of paper is placed between the two photovoltaic frames beforehand, forming a single photovoltaic frame to prevent friction damage between the two frames. This process is called the stacking process of the photovoltaic frames.

[0003] Existing palletizing equipment uses small robotic arms to grasp photovoltaic frames, and can grasp about 3-5 sets of frames at a time. However, existing packaging equipment has about 15-20 sets of frames per layer. This means that existing palletizing equipment requires the robotic arm to grasp and flip each layer about 4-6 times. In addition, in existing equipment, each conveying and flipping is carried out separately. That is, after conveying, the frame is flipped by the flipping equipment before being palletized, which is inefficient. Furthermore, multiple palletizings per layer result in the paper between each set of frames not being continuous, making subsequent disassembly very troublesome, and thus affecting the overall production efficiency of photovoltaic frames. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an automatic photovoltaic frame palletizing device, which effectively solves the problem of low efficiency due to multiple palletizing batches affecting subsequent dismantling in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0010] Furthermore, the shaft of the feeding conveyor belt is connected to a first drive motor, and the shaft of the feeding synchronous belt is connected to a second drive motor.

[0011] Furthermore, a crossbeam is provided at the bottom of the frame, and the feeding conveyor belt and the feeding synchronous belt are both installed on the crossbeam. A length adjustment assembly is installed on the crossbeam. The length adjustment assembly includes two first drive cylinders arranged on the crossbeam, and the output shafts of the two first drive cylinders face opposite directions. An adjustment plate is installed on the output shafts of the two first drive cylinders. The two adjustment plates are driven by the two first drive cylinders to move closer to each other and clamp the photovoltaic frame on the feeding synchronous belt.

[0012] Furthermore, a first rack is provided on the top wall of the frame, a transmission rod is rotatably mounted on the conveyor frame, and a first gear adapted to the first rack is fixedly mounted at both ends of the transmission rod.

A guide frame adapted to the lifting frame is fixedly installed on one side of the conveying frame. A fifth drive motor is provided on one side of the guide frame. The output shaft of the fifth drive motor rotates through the outer wall of the guide frame, and a second gear adapted to the second rack is fixedly installed on the output shaft of the fifth drive motor.

[0014] Furthermore, a bidirectional threaded rod is rotatably mounted on the inner wall of the rotating frame. The bidirectional threaded rod has two threads of the same length but opposite directions. Both clamping frames have threaded holes. The two clamping frames are installed one-to-one with the two threads on the bidirectional threaded rod through the threaded holes. When the bidirectional threaded rod rotates, the two clamping frames move closer to each other or further away from each other. The rotating frame is equipped with a fourth drive motor to drive the bidirectional threaded rod to rotate. The rotating frame has a third drive cylinder, and a pusher plate is fixedly mounted on the output shaft of the third drive cylinder. A limit frame is fixedly mounted on the rotating frame.

[0015] Furthermore, each of the two clamping frames is provided with a second driving cylinder, with a first clamping plate fixedly mounted on the output shaft of one of the second driving cylinders, and a second clamping plate elastically mounted on the output shaft of the other second driving cylinder.

[0016] Furthermore, the upper corner paper stacking mechanism also includes a first cylinder slidably mounted on the moving plate.

[0019] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0020] By conveying the photovoltaic frames to the feeding synchronous belt, a clamping frame is used to clamp and lift one half of the photovoltaic frame. During the lifting process, the frame is flipped and placed on the other half of the photovoltaic frame on the feeding synchronous belt. Then, the clamping frame is used again to clamp and stack the stacked photovoltaic frames, which improves the stacking efficiency. In addition, the paper strips in the middle layer are continuous, which facilitates subsequent disassembly. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to embodiments.

[0039] Example: Reference Figures 1-6 An automatic photovoltaic frame palletizing device includes a frame 1 and a photovoltaic frame 6. It is characterized by further including 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 drive motor 301, and the rotating shaft of the feeding synchronous belt 4 is connected to a second drive motor 401. A crossbeam 2 is provided at the bottom of the frame 1. Both the feeding conveyor belt 3 and the feeding synchronous belt 4 are installed on the crossbeam 2. A length adjustment component 5 is installed on the crossbeam 2. The length adjustment component 5 includes two first drive cylinders disposed on the crossbeam 2, with the output shafts of the two first drive cylinders facing opposite directions. An adjustment plate is installed on the output shafts of both first drive cylinders. The two adjustment plates are driven by the two first drive cylinders to move closer together 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 feeding synchronous belt 4 by the feeding conveyor belt 3. The feeding synchronous belt 4 is equipped with a limit plate and a counter. By counting the photovoltaic frames 6 that pass by, the clamping and flipping process is started when the preset number is reached. The limit plate is set at the end of the feeding synchronous belt 4 away from the feeding conveyor belt 3 to prevent the photovoltaic frame 6 from falling off the feeding synchronous belt 4.

[0041] In addition, to facilitate subsequent clamping, a length adjustment component 5 is set below the feeding synchronous belt 4. The two ends of the photovoltaic frame 6 passing through are clamped by two adjustment plates, so that the position of the photovoltaic frame 6 passing through this point is aligned.

[0042] refer to Figures 10-14To facilitate gripping and flipping, the equipment is equipped with a truss gripper mechanism for gripping and flipping the photovoltaic frame 6 on the feeding synchronous belt 4. This includes a conveyor frame 17 slidably mounted on a 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, with a first gear 20, compatible with the first rack 21, fixedly mounted at both ends of the transmission rod 19. A third drive motor 18 is provided on the conveyor frame 17 to drive the transmission rod 19. A lifting frame 22 is slidably mounted vertically within the conveyor frame 17. A second rack 24 is fixedly mounted on the outer wall of the two lifting frames 22 on opposite sides. A guide frame, compatible with the lifting frame 22, is fixedly mounted on one side of the conveyor frame 17. A fifth drive motor is provided on one side of the guide frame, with its output shaft rotatably penetrating the outer wall of the guide frame. A second gear, compatible with the second rack 24, is fixedly mounted on the output shaft of the fifth drive motor. A rotating frame 23 is rotatably mounted on the lifting frame 22. The rotating frame 23 is equipped with a rotary motor 30 for driving the rotating frame 23 to rotate 180 degrees. Two clamping frames 25 are slidably mounted on the rotating frame 23. A bidirectional threaded rod 28 is rotatably mounted on the inner side wall of the rotating frame 23. The bidirectional threaded rod 28 has two sections of threads of the same length but opposite thread directions. Both clamping frames 25 have threaded holes. The two clamping frames 25 are installed one-to-one with the two sections of threads on the bidirectional threaded rod 28 through the threaded holes. When the bidirectional threaded rod 28 rotates, the two clamping frames 25 move closer to each other or further away from each other. The rotating frame 23 is equipped with a fourth drive motor 29 for driving the bidirectional threaded rod 28 to rotate. The rotating frame 23 has a third drive cylinder, and a pusher plate 27 is fixedly mounted on the output shaft of the third drive cylinder. A limit frame 26 is fixedly mounted on the rotating frame 23. Both clamping frames 25 are equipped with second drive cylinders. A first clamping plate is fixedly mounted on the output shaft of one of the second drive cylinders, and a second clamping plate is elastically mounted on the output shaft of the other second drive cylinder.

[0043] After a preset number of photovoltaic frames 6 are reached on the aforementioned feeding synchronization frame 4, the third drive motor 18 drives the transmission rod 19 to rotate, which in turn drives the two first gears 20 to rotate. The second gear 20 meshes with the first rack 21 at the top of the frame 1, thereby achieving the purpose of the conveyor frame 17 sliding on the top of the frame 1. Figure 2 , Figure 10 and Figure 12 As shown, through the aforementioned driving method, the conveyor frame 17, the lifting frame 22, and the rotating frame 23 move to directly above the feeding synchronous belt 4. Figure 10 and Figure 11 Then, the fifth drive motor drives the second rack 24 to rotate, and the same gear and rack transmission action drives the lifting frame 22 to adjust its height, thereby adjusting the height of the rotating frame 23. The two clamping frames 25 follow the rotating frame 23 down to the position of the photovoltaic frame 6. Figure 10 and Figure 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 rotary motor 30 to rotate, thus flipping the half-layer photovoltaic frame 6. The flipped half-layer photovoltaic frame 6 is then lowered again by the lifting frame 22. By releasing the clamping frames 25, the half-layer photovoltaic frame 6 is placed on the other half-layer photovoltaic frame 6.

[0044] During the above process, the material flipping and position shifting are carried out simultaneously. 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 stacking efficiency.

[0045] The specific clamping method is as follows: the fourth drive motor 29 drives the bidirectional threaded rod 28 to rotate. When the bidirectional threaded rod 28 rotates, its two threads respectively engage with the threaded holes on the two clamping frames 25, thereby adjusting the distance between the two clamping frames 25. The two clamping frames 25 are driven to move closer to each other, that is, the two clamping frames 25 move closer to both ends of the photovoltaic frame 6. Then, the second drive cylinders on the two clamping frames 25 drive the first clamping plate and the second clamping plate to move closer to both ends of the photovoltaic frame 6, respectively. The second clamping plate is elastically installed (specifically, it is connected by a spring). This allows the half-layer photovoltaic frame 6 to move a certain distance towards the second clamping plate after clamping. The specific moving distance can be controlled by the spring's contraction length. This achieves the positional offset between this half-layer photovoltaic frame 6 and the other half-layer photovoltaic frame 6 on the lower feeding synchronous belt 4. Figure 5 The stacking method of the two photovoltaic frames 6 is shown.

[0046] refer to Figures 7-9The equipment also includes an upper corner paper stacking mechanism, comprising two moving plates 7 on either side of the feeding synchronous belt 4. Each moving plate 7 has a first gripper 9 slidably mounted on it for gripping paper strips. The moving plates 7 also have multiple second grippers 13 for conveying the paper strips. The upper corner paper stacking mechanism further includes a first cylinder 15 slidably mounted on the moving plates 7. A paper feeder 14 is fixedly mounted on the output shaft at the top of the first cylinder 15. Multiple second grippers 13 are equidistantly fixedly mounted on the paper feeder 14. A second cylinder 16 is fixedly mounted on the moving plates 7, with its output shaft slidably connected to the paper feeder 14. A sixth drive motor is mounted on the first gripper 9, and a third gear is fixedly mounted on the output shaft of the sixth drive motor. A third rack, compatible with the third gear, is mounted on the moving plates 7. A first paper roll 8 is rotatably mounted on one side of the moving plates 7, and is gripped and extracted by the first gripper 9. The paper on the moving plate 7 is provided with a cutting component 10 near the first paper roll 8. The cutting component 10 drives a scissor through a pneumatic component to cut the paper strip. The cutting component 10 is also provided with a third gripper, which clamps the paper output end of the first paper roll 8, so that the first gripper 9 can pull the paper strip from the first paper roll 8 again. The moving plate 7 is fixedly installed with a guide component for guiding the paper strip. The guide component includes a roller group 11 rotatably installed on the moving plate 7. The roller group 11 includes a first roller 1101 and a second roller 1102. The guide component also includes a forming template 12 fixedly installed on the moving plate 7. The forming template 12 has a forming hole 1201. The bottom of the frame 1 is provided with a sliding frame 32, and the sliding frame 32 is located on one side of the crossbeam 2. Two second paper 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, to prevent collisions and friction between the upper and lower photovoltaic frames 6, a strip of paper is placed between them. Specifically, the first gripper 9 holds one end of the paper roll on the first paper roll 8, and the sixth drive motor drives the third gear and third rack to slide the first gripper 9 on the moving plate 7, thereby pulling the paper roll out from the first paper roll 8. After pulling to a preset length (this length is set according to the actual length of each photovoltaic frame 6), the shearing component 10 cuts the paper out. The paper roll is cut to obtain a strip of paper. Then, the first cylinder 15 and the second cylinder 16 are used to drive the paper feeder 14 to rise, fall and move horizontally. First, it moves horizontally and at the same time, multiple second grippers 13 are activated to hold the paper strip. At this time, the first gripper 9 releases the paper strip. Then, the paper feeder 14 moves upward so that the paper strip is basically level with the top of the photovoltaic frame 6. Then, the paper feeder 14 is driven to move horizontally again to send the paper strip to the photovoltaic frame 6. At the same time, the second grippers 13 are controlled to release the paper strip. The paper strip is placed on the top wall of the photovoltaic frame 6. Then, the paper feeder 14 returns along the original path.

[0048] It is worth noting that the clamping frame 25 is relatively large and can clamp multiple photovoltaic frames 6 at the same time, so that each layer has only one whole strip of paper. In subsequent processes such as welding by the manufacturer, the stacked photovoltaic frames 6 need to be disassembled. One whole strip of paper is just right for disassembly, and there will be no paper scraps or other problems.

[0049] The first paper roll has eight guide components installed to guide and shape the paper roll, such as... Figure 8 As shown, the paper roll is squeezed as it passes through the roller assembly 11 and gradually becomes an inverted V-shape under the shaping hole 1201 of the forming mold 12. The purpose 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 mentioned above are all pneumatically driven for the purpose of clamping. This technology is existing technology and will not be elaborated further.

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

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
