Technical Field

[0001] This invention belongs to the field of photovoltaic module frame technology, specifically a manufacturing process for an integrated frame of a half-cell photovoltaic module with heat dissipation and heat conduction. Background Technology

[0002] Half-cell photovoltaic modules are photovoltaic products made by cutting conventional photovoltaic cells in half along the center line and then encapsulating them. They have the advantages of low power loss, weak hot spot effect and high power generation efficiency, and are now widely used in the photovoltaic power generation field. Half-cell photovoltaic modules need to be equipped with frames for protection, support and installation fixation. Integrated frames have become the mainstream accessories due to their high overall structural strength and good sealing performance. In order to further reduce the operating temperature rise of the module and ensure the stability of power generation, the industry has gradually developed integrated frames with integrated heat dissipation structures.

[0003] Currently, the traditional method of assembling half-cell photovoltaic module frames generally uses multiple bolts to lock and fix each section of the frame one by one to splice it into a whole frame. During the assembly process, it is necessary to align, insert bolts and tighten them in sequence. The process is complicated and time-consuming, and the amount of manual operation is large. Not only is the overall assembly efficiency low, but the many bolt connection points are also prone to problems such as uneven tightening and loosening, which makes it difficult to meet the requirements of large-scale and automated production of photovoltaic modules.

[0011] Preferably, the limiting mechanism includes a lifting plate located inside the top cylinder, with limiting rods fixedly connected to both sides of the bottom of the lifting plate. Both limiting rods penetrate the top cylinder and abut against the top of the top plate. Limiting rings are fixedly connected to both sides of the top of the top plate, and the two limiting rods are respectively inserted into the two limiting rings.

[0012] Preferably, two L-shaped round rods are symmetrically fixedly connected inside the top cylinder, and the lifting plate is movably sleeved on the outside of the two L-shaped round rods.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0031] Example 1, by Figures 1-8 The present invention relates to a manufacturing process for an integrated frame of a half-cell photovoltaic module with heat dissipation and heat conduction, comprising an upper frame 1, a lower frame 4 directly below the upper frame 1, two side frames 5 symmetrically arranged between the lower frame 4 and the upper frame 1, a splicing mechanism 2 on the upper frame 1, and a limiting mechanism 3 on the splicing mechanism 2.

[0032] In Embodiment 2, based on Embodiment 1, the splicing mechanism 2 includes a top cylinder 201 located at the top of the upper frame 1. Two locking plates 202 are symmetrically fixedly connected to the outer side of the top cylinder 201. Top blocks 203 are fixedly connected to the top of each of the two side frames 5. The upper frame 1 is fitted over the outer side of the two top blocks 203. The sides of each of the two top blocks 203 are provided with slots 2014, and the two locking plates 202 are respectively inserted into the two slots 2014. T-shaped blocks 207 are fixedly connected to the bottom of each of the two side frames 5. T-shaped grooves 6 are provided at both ends of the lower frame 4, and the two T-shaped blocks 207 are respectively inserted into the two slots 2014. Inside the T-slot 6, a top plate 2018 is fixedly installed on the top of the upper frame 1. A rotating shaft 2019 is rotatably connected to the top of the top plate 2018. The top cylinder 201 is fixed to the top of the rotating shaft 2019. A sliding rod 208 is fixedly connected to the outer side of the side frame 5. A sliding plate 204 is movably sleeved on the outer side of the sliding rod 208. The sliding plate 204 abuts against the side frame 5 to limit the sliding plate 204 and prevent it from rotating outside the sliding rod 208. A base plate 205 is fixedly connected to the bottom of the sliding plate 204. A base rod 206 is fixedly connected to the bottom of the base plate 205. The inner side of the T-slot 6 is provided with The inner hole 7 is into which the bottom rod 206 is inserted. The top of the slide plate 204 has a top groove 209 into which a top plate 2020 is inserted. The top plate 2020 is fixed to the outer side of the upper frame 1. A guide rod 2017 is fixedly connected to the inner side of the slot 2014. The guide rod 2017 abuts against the top of the plate 202. A guide block 2012 is movably sleeved on the outer side of the guide rod 2017. A spring 2013 is fixedly connected between the top of the guide block 2012 and the inner wall of the slot 2014. The spring 2013 is sleeved on the outer side of the guide rod 2017. A column 2011 is fixedly connected to the bottom of block 2012, and a protrusion 2010 is fixedly connected to the bottom of column 2011. A positioning hole is provided on the top of the card plate 202, and the protrusion 2010 is inserted into the positioning hole. A side groove 2016 is provided on the outer side of guide rod 2017. A side block 2015 is fixedly connected to the inner side of guide block 2012. The side block 2015 is slidably connected to the side groove 2016. Through the cooperation between the side block 2015 and the side groove 2016, the guide block 2012 is guided, ensuring the stability of guide block 2012 when sliding on the outer side of guide rod 2017.

[0033] First, place both side frames 5 on top of the bottom frame 4, so that the two T-blocks 207 are inserted into the two T-slots 6 respectively. Then, slide the two slide plates 204 down along the two slide rods 208 respectively, causing the two base plates 205 to descend until the two base rods 206 are inserted into the two inner holes 7 respectively.

[0034] Next, place the upper frame 1 over the outside of the two top blocks 203 until the upper frame 1 abuts against the top of the two side frames 5. At this point, the two top plates 2020 are inserted into the two top grooves 209 respectively. Then, rotate the top cylinder 201, causing the two locking plates 202 to rotate, so that the two locking plates 202 enter the two locking slots 2014 respectively. During this process, the two locking plates 202 push the two protrusions 2010 upwards, causing the two columns 2011 to rise. At the same time, the two guide blocks 2012 slide upwards along the two guide rods 2017 respectively, and the two springs 2013 are deformed. The process continues until the two clamping plates 202 rotate to their limit positions. At this point, the two guide rods 2017 abut against the top of the two clamping plates 202, and the two springs 2013 return to their original positions. This allows the two protrusions 2010 to be inserted into the two positioning holes, connecting the two top blocks 203 to the upper frame 1, thus achieving the connection between the two side frames 5 and the upper frame 1. Meanwhile, the two top plates 2020 limit the two sliding plates 204 to prevent the two bottom rods 206 from loosening, thus achieving the connection between the two side frames 5 and the lower frame 4. Finally, the rapid assembly and manufacturing of the entire half-cell photovoltaic module frame is completed.

[0035] In Embodiment 3, based on Embodiment 1, the limiting mechanism 3 includes a lifting plate 301 located inside the top cylinder 201. Limiting rods 303 are fixedly connected to both sides of the bottom of the lifting plate 301. Both limiting rods 303 penetrate the top cylinder 201 and abut against the top of the top plate 2018. Limiting rings 302 are fixedly connected to both sides of the top of the top plate 2018. The two limiting rods 303 are respectively inserted into the two limiting rings 302. Two L-shaped round rods are symmetrically fixedly connected inside the top cylinder 201. 305, the lifting plate 301 is movably sleeved on the outside of the two L-shaped round rods 305, and a screw 309 is fixedly connected inside the top cylinder 201. The lifting plate 301 is sleeved on the outside of the screw 309 and does not contact the screw 309 to avoid wear on the screw 309 when the lifting plate 301 moves. The screw 309 is threadedly sleeved on the outside of the screw 309 and a screw cylinder 304 located at the top of the lifting plate 301. A handwheel 306 is fixedly connected to the top of the screw cylinder 304 and is located inside the top cylinder 201.

[0036] First, push the lifting plate 301 to slide it downwards along the two L-shaped rods 305, causing the two limiting rods 303 to descend and insert into the two limiting rings 302 respectively, until the two limiting rods 303 abut against the top plate 2018. Then, rotate the handwheel 306 clockwise to drive the screw cylinder 304 to rotate and descend outside the screw 309, thereby limiting the lifting plate 301 and preventing the two limiting rods 303 from loosening. This fixes the top cylinder 201 to the top plate 2018 and prevents the two clamping plates 202 from being removed from the two clamping slots 2014 respectively, thus ensuring the stability of the entire frame after assembly.

[0037] In Example 4, based on Example 1, a sealing ring 307 is fixedly connected to the bottom end of the screw cylinder 304. The sealing ring 307 is attached to the top of the lifting plate 301. A sealing ring 308 is fixedly connected to the inner bottom wall of the top cylinder 201. The sealing ring 308 is attached to the bottom of the lifting plate 301.

[0038] When the lifting plate 301 descends along the two L-shaped round rods 305 until both limit rods 303 abut against the top plate 2018, the lifting plate 301 is in contact with the second sealing ring 308. When the screw cylinder 304 is tightened on the outside of the screw 309, the first sealing ring 307 is in contact with the lifting plate 301, thus achieving a sealing protection for the screw 309 and preventing the screw 309 from being exposed to the outside and corroded.
