Description

Technical Field

[0001] This application relates to the field of photovoltaic frame processing technology, and in particular to an automatic material receiving and stacking device for photovoltaic steel frames. Background Technology

[0002] Photovoltaic steel frames are metal profile components used in the assembly of photovoltaic modules. After being cut, punched, and bent, the steel frames need to be collected, sorted, and stacked in layers for convenient centralized transportation and warehousing, as well as subsequent photovoltaic module assembly. With the large-scale production in the photovoltaic industry, the daily output of steel frames is high, and individual profiles are heavy and long. This results in high labor intensity at the rear-end stacking station, making automated material collection and stacking equipment a necessity for production line upgrades.

[0003] Currently, the end of photovoltaic steel frame processing production lines generally adopts a manual-assisted material stacking operation mode. After the formed steel frames are discharged from the conveyor line, workers manually pick up individual frames, manually align the ends and sides of the profiles, and then stack them in layers into the material rack. Some production lines are equipped with simple roller conveyor tables to assist in material transfer, which can only realize unidirectional conveying and buffering of steel frames. The entire process relies entirely on manual labor to pick up, straighten, and stack materials. The conveyor table only plays a temporary auxiliary role in supporting materials.

[0004] Regarding the aforementioned technologies, the inventors believe that workers repeatedly moving heavy steel frames is labor-intensive and costly. Manually aligning the frames relies on visual judgment, resulting in poor uniformity and messy stacking patterns. Summary of the Invention

[0005] The purpose of this application is to provide an automatic material receiving and stacking device for photovoltaic steel frames, so as to improve the problems of workers repeatedly handling heavy steel frames, which is labor-intensive, has high labor costs, and relies on visual judgment for manual alignment of frames, resulting in poor uniformity and messy stacking patterns.

[0006] The automatic photovoltaic steel frame receiving and stacking device provided in this application adopts the following technical solution: An automatic photovoltaic steel frame receiving and stacking device includes a frame, a conveying component for conveying steel frames is arranged above the frame, a receiving component one for receiving steel frames is arranged on one side of the frame, an inclined guide frame corresponding to the receiving component one is arranged above the frame, a receiving component two for receiving steel frames is arranged below the inclined guide frame, and steel frames are placed above the receiving component two. A stacking rack for storing steel frames is arranged on one side of the frame, and a gantry-type robotic arm for transporting and stacking the steel frames is arranged between the frame and the stacking rack.

[0007] By adopting the above technical solution, the conveying component continuously conveys the formed steel frame, the receiving component one receives the material and pushes the frame to the inclined guide frame, the inclined guide frame diverts the frame to the receiving component two below to complete the single-piece neat placement, the gantry robotic arm grabs multiple neatly placed steel frames on the receiving component two at once, and transfers them to the stacking rack for layered stacking; the diversion buffer structure can match the continuous output speed of the production line, and completes the entire process of receiving, unloading, neat placement, automatic handling and stacking in segments, without the need for manual intervention, realizing fully automatic and uninterrupted material receiving and stacking.

[0008] Optionally, the gantry robotic arm's execution end is provided with a lifting frame that contacts the bottom of the steel frame. The upper surface of the lifting frame is lower than the top of the receiving component two. The stacking rack is provided with a clearance space corresponding to the gantry robotic arm and the lifting frame on the side facing the gantry robotic arm.

[0009] By adopting the above technical solution, a bottom-supported lifting frame is used to replace manual lifting of the steel frame with both hands. There is no need for manual bending over to lift heavy profiles. The bottom supports the entire structure evenly and will not squeeze the side walls of the steel frame, causing the profile to deform. The height of the lifting frame is lower than the top of the receiving component two. The lifting frame can be directly extended into the bottom of the placement station to complete the material picking, simplifying the picking action and improving the stacking cycle. A clearance space is provided on one side of the stacking frame, so that the gantry robot arm carrying the lifting frame can directly extend into the stacking frame to place the steel frame.

[0010] Optionally, the conveying assembly includes a conveyor belt disposed above the frame and corresponding to the receiving assembly, and a conveyor frame connected to the conveyor belt. The receiving assembly includes a conveyor belt connected to the end of the conveyor belt and a mounting frame supporting the conveyor belt. One side of the conveyor belt contacts the higher side of the inclined guide frame, and a drop gap corresponding to the steel frame is left between the lower side of the inclined guide frame and the frame.

[0011] By adopting the above technical solution, the first conveyor belt smoothly transports the steel frame output from the production line to the first conveyor belt. The first receiving component serves as a primary buffer receiving station, continuously receiving uninterrupted output. The inclined guide frame forms an inclined flow channel, and the steel frame slides down the inclined surface by its own weight. The drop gap controls the sequential drop of a single frame, avoiding the simultaneous stacking of multiple frames and achieving orderly diversion of material.

[0012] Optionally, the mounting frame is provided with a push plate on the side away from the inclined guide frame to push the steel frame into the inclined guide frame and a drive component to drive the push plate to move. The inclined guide frame is provided with a number of rollers that rotatably contact the steel frame along its length.

[0013] By adopting the above technical solution, the drive unit drives the push plate to automatically push the steel frame into the inclined guide frame. The pushing force is stable, and each profile can be accurately fed into the inclined surface without material leakage or jamming. The inclined guide frame is equipped with rollers, which convert the sliding friction of the steel frame into rolling friction. The profile slides down smoothly without jamming, preventing hard friction from scratching the frame surface during pushing and reducing the product defect rate. The rollers support the steel frame to slide down evenly, and the profile falls in a uniform manner, further simplifying the back-end straightening process.

[0014] Optionally, the receiving component two includes a placement frame for receiving the steel frame falling at the drop gap position below the inclined guide frame. The placement frame is arranged along the length direction of the lifting frame toward the gantry-type robotic arm. The frame is provided with a pushing block for pushing the steel frame and a driving component two for driving the pushing block to move toward the placement frame.

[0015] By adopting the above technical solution, the placement frame supports the steel frame that falls obliquely, and the second drive unit controls the push block to push back and forth. Each time a frame falls, a horizontal push is completed, so that multiple steel frames are evenly and equidistantly arranged along the length of the placement frame, achieving horizontal regularity of the frames. This provides a regular foundation for the robotic arm to lift and pick up materials in a row, resulting in a large single material stacking capacity and improved stacking efficiency.

[0016] Optionally, a support frame is provided below the placement frame to contact the lifting frame. The placement frame and the support frame are slidably connected. The support frame is provided with a linear module that drives the placement frame to move toward the side wall of the lifting frame. A limiting baffle is provided on the side of the placement frame away from the lifting frame to contact the end of the steel frame.

[0017] By adopting the above technical solution, the linear module drives the entire display rack to slide, and the limit baffle automatically abuts against the ends of all steel frame edges, completing the alignment of the entire row of profile ends in one go, eliminating misalignment of lengths, saving the process of repeated manual alignment, reducing the amount of manual labor, and the support frame provides stable support for the display rack. At the same time, it reserves space for the lifting frame to extend in. The two processes of horizontal regularization and end alignment are completed simultaneously, which greatly improves the regularization accuracy of the frame.

[0018] Optionally, a number of rollers are also rotatably arranged above the placement frame, and a clearance groove corresponding to the bottom of the lifting frame is opened at the bottom of the support frame.

[0019] By adopting the above technical solutions, the rollers at the top of the placement rack reduce friction and wear during the pushing and alignment of the steel frame, protecting the surface of the steel frame; the bottom clearance groove of the support frame allows the lifting frame to extend directly into the bottom of the placement rack from below, so that the lifting frame can complete the lifting and picking of materials without large lifting and lowering, simplifying the movement stroke of the robotic arm and improving the stacking cycle speed.

[0020] Optionally, the frame is provided with an extension plate extending along the height direction on the side of the drop gap away from the inclined guide frame, and the frame is provided with a lifting frame for receiving the steel frame at the drop gap position, and a driving component three for driving the lifting frame to move is provided below the lifting frame.

[0021] By adopting the above technical solution, the lifting frame supports the steel frame that slides down along the inclined guide frame, buffers the impact of free fall, and avoids the frame from directly hitting the placement frame and causing it to bounce or deviate; after the driving component three drives the lifting frame to descend smoothly, it releases the frame, so that the steel frame falls smoothly to the designated position of the placement frame, and the extension plate restricts the steel frame from sliding laterally, preventing the problem of material misalignment or skew.

[0022] Optionally, the lifting frame is provided with a limiting plate at one end away from the frame that contacts the side wall of the steel frame, and a rubber buffer layer is provided above the lifting frame that contacts the bottom of the steel frame.

[0023] By adopting the above technical solution, the limiting plate fits the side of the steel frame, constrains the lateral displacement of the frame during the lifting process, and ensures that the entire row of frames moves synchronously; the rubber buffer layer isolates the hard contact between metal and absorbs the vibration generated when the lifting frame lifts, prevents the steel frame from shifting its position, avoids scratching the bottom surface of the steel frame when the lifting frame lifts, and improves the yield of the finished product.

[0024] Optionally, the stacking rack is provided with a plurality of placement racks for placing steel frames along the height direction, and adjacent placement racks form placement slots corresponding to the steel frames. The side wall of the stacking rack is provided with a baffle that contacts the end of the steel frame.

[0025] By adopting the above technical solution, the multi-layer placement rack forms independent placement slots, which can stack multiple rows of steel frames to increase the storage capacity of a single stack; the side wall baffle limits the ends of the frame when the robotic arm releases materials, ensuring that each layer of frame is neatly stacked and the stack shape is regular and uniform, which facilitates subsequent transfer and unloading.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying component continuously conveys the formed steel frame. The receiving component one receives the material and pushes the frame to the inclined guide frame. The inclined guide frame diverts the frame and drops it to the receiving component two below for single-piece neat placement. The gantry-type robotic arm grabs multiple neatly placed steel frames from the receiving component two at once and transfers them to the stacking rack for layered stacking. The diversion and buffer structure can match the continuous output speed of the production line, completing the entire process of receiving, unloading, neat placement, and automatic handling and stacking in segments without manual intervention, achieving fully automatic and uninterrupted material receiving and stacking. 2. The placement frame supports the steel frame that falls obliquely. The second drive unit controls the push block to push back and forth. Each time a frame falls, a horizontal push is completed, so that multiple steel frames are evenly and equidistantly arranged along the length of the placement frame, achieving horizontal regularity of the frames. This provides a regular foundation for the robotic arm to lift and pick up materials in a row, resulting in a large single material stacking capacity and improved stacking efficiency. 3. The limiting plate fits against the side of the steel frame, restraining the lateral displacement of the frame during the lifting process and ensuring that the entire row of frames moves synchronously; the rubber buffer layer isolates the hard metal contact, absorbs the vibration generated when the lifting frame is lifted, prevents the steel frame from shifting its position, avoids scratching the bottom surface of the steel frame when the lifting frame is lifted, and improves the yield of the finished product.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0030] Automatic photovoltaic steel frame receiving and stacking device, refer to Figure 1 and Figure 2The system includes a frame 1 that serves as the overall support structure, a conveying assembly 2 mounted on top of the frame 1, which connects to the discharge end of the front steel frame forming production line, and a receiving assembly 3 that connects to the conveying assembly 2 on one side of the frame 1 as a primary buffer receiving station; an inclined guide frame 11 is installed on top of the frame 1, with the high end of the guide frame connecting to the receiving assembly 3 and the low end leaving a clearance 12 between it and the frame 1, and a receiving assembly 4 positioned below the inclined guide frame 11 as a steel frame unloading and automatic sorting station; a stacking rack 5 is independently installed on the outside of the frame 1 for layered storage of steel frames, and a gantry-type robotic arm 6 is installed between the frame 1 and the stacking rack 5 to transport the neatly sorted rows of steel frames from the receiving assembly 4 to the stacking rack 5 for stacking.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The conveying assembly 2 is composed of a conveyor belt 21 and a conveyor frame 22. The conveyor frame 22 is fixed to the top of the frame 1. The conveyor belt 21 receives the steel frame output from the production line and continuously conveys it forward. The receiving assembly 3 includes a conveyor belt 31 and a mounting frame 32 connected to the conveyor belt 31. The side wall of the mounting frame 32 is connected to the frame 1. The input end of the conveyor belt 31 is seamlessly connected to the end of the conveyor belt 21. The output end of the conveyor belt 31 is attached to the side of the higher end of the inclined guide frame 11. A push plate 33 and a drive component 34 are installed on the side of the mounting frame 32 facing away from the inclined guide frame 11. The drive component 34 can be a linear drive component such as a cylinder or an electric push rod. The push plate 33 moves laterally under the drive component 34, pushing the steel frame that is on the conveyor belt 31 to the inclined guide frame 11. The guide frame 11 is inclined and has several rollers 7 installed evenly along the length of the profile. After the steel frame is pushed to the inclined surface, it slides down along the rollers 7 and moves down the falling gap 12 by its own weight. The frame 1 extends upward on the side of the falling gap 12 away from the inclined guide frame 11 to form an extension plate 14. The extension plate 14 blocks the steel frame sliding down along the inclined guide frame 11, so that the steel frame falls smoothly into the falling gap. The lifting frame 15 is vertically arranged at the falling gap 12. The bottom of the lifting frame 15 is equipped with a drive component 3 16 to realize the lifting action. The drive component 3 16 can also be a linear drive component such as a cylinder or an electric push rod. After the steel frame slides down to the surface of the lifting frame 15, the drive component 3 16 drives the lifting frame 15 to slowly descend and place the steel frame smoothly on the receiving component 2 4 below.

[0032] Reference Figure 2 and Figure 3The receiving component 4 includes a placement frame 41 for receiving steel frames. The placement frame 41 is positioned opposite the falling gap 12 to receive the steel frames. A push block 42 and a driving component 43 are installed on the side of the frame 1 facing the placement frame 41. The driving component 43 drives the push block 42 to move back and forth laterally. The driving component 16 can also be a linear driving component such as a cylinder or an electric push rod. After each steel frame falls onto the placement frame 41, the push block 42 pushes the frame forward to the designated position and then automatically retracts. The steel frames falling in sequence are pushed one by one and evenly linearly arranged on the placement frame 41. The bottom of the placement frame 41 is slidably mounted on top of the support frame 13. 3. The built-in linear module 44 drives the placement frame 41 to slide horizontally as a whole. The linear module is a screw driven by electrodes. The rotation of the screw drives the placement frame 41, which is threadedly connected to the screw, to move. The end of the placement frame 41 away from the gantry robot arm is fixed with a limiting baffle 45. When the linear module 44 drives the placement frame 41 to move to one side of the robot arm, the limiting baffle 45 simultaneously fits all the ends of the steel frame to uniformly correct the alignment of the frame ends. Several rollers 7 are also arranged on the upper surface of the placement frame 41. The bottom of the support frame 13 has a clearance groove 131. The space of the clearance groove 131 matches the outer dimensions of the lifting frame 61 installed at the end of the gantry robot arm.

[0033] Reference Figure 2 and Figure 3 A gantry-type robotic arm 6 spans above the frame 1 and the stacking rack 5. The vertical execution end of the robotic arm is fixed with a lifting frame 61. The overall height of the lifting frame 61 is lower than the top plane of the placement rack 41. The lifting frame 61 can extend downward into the bottom clearance groove 131 of the support frame 13 to lift the entire row of steel frame from the bottom of the placement rack 41. A limiting plate 62 extends upward from the end of the lifting frame 61 away from the frame 1. The upper surface of the lifting frame 61 is fully covered with a rubber buffer layer 63. When lifting the steel frame, the limiting plate 62 fits against the side of the frame for limitation, and the rubber buffer layer 63 isolates hard metal contact.

[0034] Reference Figure 1 and Figure 4 The stacking rack 5 is independently arranged on the side of the frame 1. The stacking rack 5 has multiple sets of placement racks 52 installed in layers along the vertical height. An independent placement slot 521 is formed between two adjacent layers of placement racks 52 for storing a single row of steel frames. The stacking rack 5 has a large clearance space 51 reserved on the side facing the gantry robot arm, so that the lifting frame 61 can carry the steel frame directly into the placement slot 521 to complete the unloading. The side wall of the stacking rack 5 is fixed with a baffle 53. When the steel frame is put into the placement slot 521, the baffle 53 abuts against the end of the profile to ensure that each layer of frame is stacked flat.

[0035] The implementation principle of this application embodiment is as follows: The steel frames produced by the front-end photovoltaic steel frame production line are continuously conveyed to the conveyor component 2. The conveyor belt 21 transfers the steel frames to the conveyor belt 31 of the receiving component 3 for buffering. The drive component 34 drives the pusher plate 33 to periodically push the single steel frame into the inclined guide frame 11. The steel frame slides smoothly down the inclined roller 7 and falls onto the surface of the lifting frame 15. The drive component 3 16 controls the lifting frame 15 to slowly descend and smoothly release the steel frame onto the placement frame 41. After the steel frame falls onto the placement frame 41, the drive component 2 43 drives the pusher block 42 to push the frame forward. After the push is completed, the pusher block 42 automatically resets and waits for the next steel frame to fall and repeats the push action, so that multiple steel frames are evenly arranged in a straight line on the placement frame 41. The straight module 44 drives the placement frame 41 to slide towards the gantry robot arm. The end limit baffle 45 of the placement frame 41 simultaneously fits the ends of all steel frames to complete the alignment and correction of the steel frame ends. The top roller 7 of the placement frame 41 reduces the friction and wear of the steel frames during the pushing and alignment process. After a specified number of neatly arranged steel frames have accumulated on the placement rack 41, the gantry-type robotic arm 6 moves the lifting frame 61 to the bottom of the support frame 13. The lifting frame 61 extends through the clearance groove 131 of the support frame 13 and into the space below the placement rack 41, lifting the entire row of steel frames upwards. The rubber buffer layer 63 on the lifting frame 61 protects the bottom surface of the steel frames, and the end limiting plate 62 constrains the profiles to prevent lateral sliding. The robotic arm carries the entire row of steel frames and moves them horizontally to one side of the stacking rack 5, relying on the clearance space 51 reserved by the stacking rack 5 to extend into the placement grooves of each layer. Inside 521, the steel frame is slowly lowered onto the placement rack 52. The side wall baffle 53 of the stacking rack 5 limits the end of the steel frame, completing the single-layer stacking. After the single-layer stacking is completed, the gantry robotic arm resets and repeats the above process of receiving, diverting, tidying, transporting and stacking. The multi-layer placement slots 521 stack the steel frames in sequence, realizing the fully automatic continuous receiving, tidying and layered stacking of photovoltaic steel frames. No manual intervention is required throughout the process. The material drop buffer, bidirectional tidying and interference-free material picking and stacking are completed in a coordinated manner, realizing fully automatic and uninterrupted material receiving and stacking.
