Description

Technical Field

[0001] This invention relates to the field of photovoltaic modules, and more particularly to a steel frame suspension fixture for photovoltaic modules for loading and unloading. Background Technology

[0002] Steel frames are an important component of photovoltaic modules, and their manufacturing quality significantly impacts the assembly quality of photovoltaic modules and the construction quality of photovoltaic power plants. During the forming and processing of steel frames, saponified liquid, iron filings, and other stains may adhere to their surface, affecting the adhesion of the steel frame surface during the coating process. Therefore, cleaning of steel frame products is necessary.

[0003] For batch steel frames, a hanging fixture is generally used to hang the steel frames in an orderly manner. The loading and unloading operations of the hanging fixture before cleaning and coating the steel frames are carried out manually. Each manual operation can only load one frame to the hanging point of the hanging fixture at a time, which results in high work intensity for the operators and low production efficiency. Summary of the Invention

[0004] Based on the above problems, the purpose of this invention is to provide a steel frame suspension fixture loading and unloading device for photovoltaic modules, which realizes fully automatic operation, high efficiency and matching the loading and unloading actions of the suspension fixture, and meets the cleaning requirements of the steel frame.

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

[0006] A steel frame suspension fixture for photovoltaic modules, comprising:

[0007] A frame conveyor line is used to transport steel frame products along the width of the steel frame.

[0008] Feed roller conveyor, used to convey steel frame products along the length of the steel frame;

[0009] Hanging fixture transfer line, on which hanging fixtures are placed, the hanging fixtures are used to suspend several steel frame products vertically so as to carry out batch cleaning operations of steel frame products;

[0010] The feeding roller conveyor is used to convey steel frame products along the length of the steel frame.

[0011] The material sorting and positioning mechanism is used to move a preset number of steel frame products from the frame conveyor line to the feed roller line, and to arrange the steel frame products at equal intervals on the feed roller line.

[0012] The loading and unloading mechanism is used to hoist the steel frame products on the feeding roller line to the hanging fixture, and to pick up and place the steel frame products on the hanging fixture onto the unloading roller line.

[0013] The return mechanism is used to move steel frame products from the unloading roller line back to the frame conveyor line.

[0014] Optionally, the material positioning mechanism includes a first frame located above the frame conveyor line and the feed roller line. The first frame is equipped with a loading rack that can move horizontally and vertically. The loading rack is equipped with two movable plates with adjustable spacing along the length of the steel frame. Each movable plate is equipped with multiple pneumatic fingers that correspond one-to-one with a preset number of steel frame products. The pneumatic fingers clamp and fix the ends of the steel frame products.

[0015] Optionally, the material distribution and positioning mechanism also includes a second frame located below the feed roller line. The second frame is equipped with a lifting platform, and the lifting platform is equipped with support rods arranged along the length of the steel frame. Multiple support rods correspond one-to-one with a preset number of steel frame products and are arranged side by side. The support rods are equipped with limit blocks that pass through the feed roller line and limit and guide the steel frame products.

[0016] Optionally, a spacing assembly is provided on both the moving plate and the lifting platform. The spacing assembly includes guide rods arranged along the width direction of the steel frame. A fixed block is provided at the end of the guide rod, and multiple sliding blocks are sleeved on the guide rod. A pneumatic finger or support rod is installed on each sliding block. The fixed block is connected to the adjacent sliding block, and two adjacent sliding blocks are connected by a scissor-type linkage structure, so that the spacing between each sliding block can be changed by driving any sliding block.

[0017] Optionally, the loading and unloading mechanism includes a third frame located above the feed roller line or unloading roller line and on one side of the hanger transfer line. The third frame is equipped with a transfer frame capable of translation and lifting. The transfer frame is equipped with a turning table capable of changing between a horizontal and a vertical state. The turning table is equipped with several pneumatic grippers corresponding to the steel frame products distributed at intervals. The pneumatic grippers are used to clamp the steel frame products.

[0018] Optionally, the fixture transfer line includes a fourth frame, on which two parallel conveyor chains are provided. Each conveyor chain has a baffle on its outer side. The two sides of the suspension fixture are limited by the baffles and supported by the conveyor chains, so that multiple suspension fixtures are fed in an orderly manner in the fixture transfer line.

[0019] Optionally, the fourth frame is provided with an end push plate, a side push plate, and an upper pressure plate at the position corresponding to the docking position with the feed roller line or the unloading roller line. The end push plate is used to position the end of the suspension fixture when hoisting or picking up and placing the steel frame product. The side push plate is used to position the side of the suspension fixture when hoisting or picking up and placing the steel frame product. The upper pressure plate is used to apply pressure to the upper surface of the suspension fixture when hoisting or picking up and placing the steel frame product.

[0020] Optionally, a hanger buffer line is provided between the hanger transfer line connected to the infeed roller line and the hanger transfer line connected to the unfeed roller line, and the steel frame products to be cleaned wait for offline cleaning and return on the hanger buffer line.

[0043] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 and Figure 2As shown, this preferred embodiment provides a steel frame suspension fixture loading and unloading equipment for photovoltaic modules, including a frame conveyor line 1, an infeed roller line 2, a fixture transfer line 3, an unloading roller line 4, a material sorting and positioning mechanism 5, a loading and unloading mechanism 6, and a return mechanism 7.

[0045] The frame conveyor line 1 is used to convey the steel frame product 10 along the width direction of the steel frame. Here, a belt conveyor is preferred for lateral conveying.

[0046] Both the infeed roller conveyor 2 and the unfeed roller conveyor 4 are used to convey the steel frame product 10 along the length of the steel frame. Based on the longitudinal conveying requirements, roller conveying is preferred here.

[0047] Among them, the hanging transfer line 3 is equipped with a hanging fixture 8, which is used to suspend several steel frame products 10 vertically for batch cleaning of steel frame products 10. With the help of an external robot, the hanging fixture 8 and steel frame products 10 can be loaded and unloaded to the cleaning and coating production line.

[0048] Preferably, the frame conveyor line 1 and the hanger transfer line 3 are arranged in parallel, and the feed roller line 2 and the unloading roller line 4 are arranged in parallel, thus forming a "U"-shaped product flow path, maximizing equipment space utilization and ensuring flow efficiency.

[0049] See details Figure 3 The fixture transfer line 3 here includes a fourth frame 31, on which two parallel conveyor chains 32 are provided. Each conveyor chain 32 has a baffle 33 on its outer side. The two sides of the suspension fixture 8 are limited by the baffle 33 and supported by the conveyor chain 32, so that multiple suspension fixtures 8 are fed in an orderly manner in the fixture transfer line 3.

[0050] Specifically, the fourth frame 31 is provided with an end push plate 34, a side push plate 35, and an upper pressure plate 36 at the position corresponding to the docking position with the feed roller line 2 or the unloading roller line 4. The end push plate 34 is used to position the end of the suspension fixture 8 when hoisting or picking up the steel frame product 10. The side push plate 35 is used to position the side of the suspension fixture 8 when hoisting or picking up the steel frame product 10. The upper pressure plate 36 is used to apply pressure to the upper surface of the suspension fixture 8 when hoisting or picking up the steel frame product 10, thereby ensuring that the position of the suspension fixture 8 is stable when hoisting or picking up the steel frame product 10, so as to ensure accurate operation of the subsequent loading and unloading mechanism 6.

[0051] Furthermore, a hanger buffer line 9 is provided between the hanger transfer line 3 connected to the feed roller line 2 and the hanger transfer line 3 connected to the unloading roller line 4. The steel frame product 10 to be cleaned waits for offline cleaning and return on the hanger buffer line 9.

[0052] See details Figure 4 To facilitate mechanized hoisting and handling of the steel frame product 10, the suspension fixture 8 here includes a frame 81. The top of the frame 81 is equipped with a hook 82, and the bottom of the frame 81 is equipped with several vertical lifting rods 83. The side surface of the lifting rods 83 is equipped with protruding spring pieces 84.

[0053] When the lifting rod 83 is inserted into the cavity of the steel frame product 10 from the end of the steel frame product 10, and the protruding spring piece 84 abuts against the inner wall of the cavity, the steel frame product 10 is clamped on the suspension fixture 8; when the steel frame product 10 is pulled off the lifting rod 83 by force, the pressing function of the protruding spring piece 84 fails, and the steel frame product 10 is removed from the suspension fixture 8.

[0054] The material distribution and positioning mechanism 5 is used to move a preset number of steel frame products 10 from the frame conveyor line 1 to the feed roller line 2, and to arrange the steel frame products 10 at equal intervals on the feed roller line 2.

[0055] See details Figure 5 and Figure 6 The material distribution and positioning mechanism 5 includes a first frame 51 located above the frame conveyor line 1 and the feed roller line 2. The first frame 51 is equipped with a loading rack 52 capable of translation and lifting. The loading rack 52 is equipped with two movable plates 53 with adjustable spacing along the length of the steel frame. Each movable plate 53 is equipped with multiple pneumatic fingers 54 corresponding to a preset number of steel frame products 10. The pneumatic fingers 54 clamp and fix the ends of the steel frame products 10.

[0056] The longitudinal clamping method is adopted here because there is a distance requirement between adjacent steel frame products 10. Given that the steel frame products 10 change from horizontal to vertical conveying and multiple steel frame products 10 are matched with the subsequent loading and unloading mechanism 6 and the suspension fixture 8 at the same time, it is necessary to determine the relative position between the steel frame products 10. Therefore, in addition to stable transfer, accurate positioning is also required.

[0057] See details Figure 7 The material distribution and positioning mechanism 5 also includes a second frame 55 located below the feed roller line 2. The second frame 55 is equipped with a lifting platform 56. The lifting platform 56 is equipped with support rods 57 arranged along the length of the steel frame. Multiple support rods 57 correspond one-to-one with a preset number of steel frame products 10 and are arranged side by side. The support rods 57 are equipped with limiting blocks 58 that pass through the feed roller line 2 and limit and guide the steel frame products 10, thereby ensuring that each steel frame product 10 maintains a set spacing.

[0058] Furthermore, initially, a preset number of steel frame products 10 are input side-by-side on the frame conveyor line 1. For different spacing requirements, a spacing component 59 is provided on the moving plate 53 and the lifting platform 56. The spacing component 59 includes guide rods 591 arranged along the width direction of the steel frame. A fixing block 592 is provided at the end of the guide rod 591, and multiple sliding blocks 593 are sleeved on the guide rod 591. A pneumatic finger 54 or a support rod 57 is installed on each sliding block 593. The fixing block 592 is connected to the adjacent sliding block 593, and two adjacent sliding blocks 593 are connected by a scissor-type linkage structure 594. Thus, by driving any sliding block 593, the spacing of each sliding block 593 can be changed to meet the spacing requirements of each pneumatic finger 54 and each support rod 57.

[0059] The scissor linkage structure 594 typically consists of two scissor-shaped linkages forming a parallelogram region. By changing the shape of the parallelogram, the distance between the two ends can be changed. This is existing technology and will not be described further here.

[0060] The loading and unloading mechanism 6 is used to hoist the steel frame product 10 on the feeding roller line 2 to the hanging fixture 8, and to pick up and place the steel frame product 10 on the hanging fixture 8 to the unloading roller line 4.

[0061] See details Figure 8 The loading and unloading mechanism 6 includes a third frame 61 located above the infeed roller line 2 or the unfeed roller line 4 and on one side of the hanging transfer line 3. The third frame 61 is equipped with a transfer rack 62 that can move horizontally and vertically. The transfer rack 62 is equipped with a turning table 63 that can switch between a horizontal and a vertical state. The turning table 63 is equipped with several pneumatic grippers 64 corresponding to the steel frame products 10 distributed at various intervals. The pneumatic grippers 64 are used to clamp the steel frame products 10, thereby switching the steel frame products 10 from a flat state to a vertical state to meet the cleaning requirements.

[0062] The return mechanism 7 is used to move the steel frame product 10 on the unloading roller line 4 back to the frame conveyor line 1.

[0063] Specifically, the conveying plane of the unloading roller line 4 is higher than the conveying plane of the frame conveying line 1. The return mechanism 7 includes a roller segment 71 that can move up and down. When the roller segment 71 is in the raised state, the roller segment 71 is connected to the end of the unloading roller line 4. When the roller segment 71 is in the lowered state, the roller segment 71 is embedded in the frame conveying line 1, thereby realizing the smooth transition of the steel frame product 10 from longitudinal conveying to transverse conveying.

[0064] Action process:

[0065] During equipment operation, the frame conveyor line 1 transports a batch of steel frame products 10 to the sorting and positioning mechanism 5. The sorting and positioning mechanism 5 separates several steel frames in this batch of steel frame products 10 (the number of separated steel frames corresponds to the number of hanging points of the suspension fixture 8, and the separation distance is consistent with the distance between the hanging points of the suspension fixture 8). The feed roller line 2 transfers the separated steel frame products 10 to the loading and unloading mechanism 6. The loading and unloading mechanism 6 grabs the separated steel frame products 10 in one go and hoists them onto the lifting rod 83 of the suspension fixture 8. After cleaning and coating, the steel frame products 10 are picked up and placed from the hanging points of the suspension fixture 8 by the loading and unloading mechanism 6 onto the unloading roller line 4. The return mechanism 7 carries the steel frame products 10 on the unloading roller line 4 back to the frame conveyor line 1, and the frame conveyor line 1 transfers the steel frame products 10 to the next process.

[0066] In summary, the aforementioned photovoltaic module steel frame hanging fixture loading and unloading equipment can complete the batch hanging operation of steel frames, and can automatically load and unload the hanging fixture at the steel frame cleaning and coating process to achieve unmanned operation, which greatly reduces the time of personnel working in harsh environments and greatly improves production efficiency.

[0067] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
