Description

Technical Field

[0002] Photovoltaic cables are specialized power transmission cables used in photovoltaic power station systems to connect photovoltaic modules, combiner boxes, and inverters. They must have good insulation, weather resistance, and conductivity. During their automated production, they must be continuously and stably transported by a conveying mechanism to meet the requirements of subsequent processing steps such as cutting, stripping, and crimping.

[0003] Existing photovoltaic cable conveying devices mostly use tensioning wheels in fixed positions to tension and guide the cables. Because the installation position of the tensioning wheels is fixed and cannot be adjusted, it is impossible to adjust the tension in real time according to the cable conveying speed, cable laying status and working conditions. It is difficult to achieve adaptive adjustment and control of cable tension, which can easily lead to problems such as the cable being too loose and running off-center or too tight and stretching and deforming, affecting the conveying stability and processing quality of photovoltaic cables.

[0029] 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.

[0030] Example 1, by Figures 1-7 The present invention relates to a tension adaptive adjustment conveying control device for photovoltaic cable production, comprising a base 1, a driving wheel 6 and a driven wheel 5 above the base 1, the driven wheel 5 being located directly above the driving wheel 6, an adjustment mechanism 2 and a traction mechanism 3 being provided on the top of the base 1, and a limiting mechanism 4 being provided on the adjustment mechanism 2.

[0031] In Embodiment 2, based on Embodiment 1, the adjusting mechanism 2 includes a bracket 201 fixed to the top of the base 1. Both sides of the bracket 201 have through slots 203. Inner rods 2022 are fixedly connected to the inner sides of both through slots 203. A lifting plate 2016 is movably sleeved between the two inner rods 2022. A U-shaped frame 2023 is fixedly connected to the top of the lifting plate 2016. Two tension sensors 2015 are symmetrically fixedly connected to the inner side of the U-shaped frame 2023. A bearing 2014 is fixedly connected to the detection end of each tension sensor 2015. A tension roller 204 is rotatably connected between the two bearings 2014. The outer side of the bracket 201... An L-shaped seat 207 is fixedly connected. A connecting column 206 is fixedly connected between the L-shaped seat 207 and the bracket 201. A U-shaped plate 202 is movably sleeved on the outer side of the connecting column 206. The U-shaped plate 202 is located on the outer side of the bracket 201, and two guide rollers 2013 are symmetrically rotatably connected to the bottom of the U-shaped plate 202. A support shaft 2017 is rotatably connected to the inner side of the bracket 201. A bidirectional lead screw 2018 is fixedly connected to one end of the support shaft 2017. Two threaded nuts 2021 are symmetrically threaded on the outer side of the bidirectional lead screw 2018. A crossbar 2019 located below the bidirectional lead screw 2018 is fixedly connected to the inner side of the bracket 201. Both nut 2021 are movably sleeved on the outside of crossbar 2019. Two movable rods 2020 are symmetrically rotatably connected to the bottom of lifting plate 2016. The bottom ends of the two movable rods 2020 are rotatably connected to the tops of the two nut 2021. An adjusting shaft 2011 is fixedly connected to the end of the bidirectional lead screw 2018 away from the support shaft 2017. The end of the adjusting shaft 2011 away from the bidirectional lead screw 2018 extends to the outside of bracket 201 and is fixedly connected to an adjusting motor 209. The adjusting motor 209 is fixed on L-shaped seat 207. Both tension sensors 2015 are electrically connected to the adjusting motor 209. The outside of bracket 201 is fixedly installed... The device includes a controller, an adjusting motor 209 electrically connected to the controller, a turntable 2010 fixedly sleeved on the outer side of the adjusting shaft 2011, an adjusting rod 208 rotatably connected to the outer side of the turntable 2010, and the bottom end of the adjusting rod 208 rotatably connected to the outer side of the U-shaped plate 202. Side grooves 205 are provided on both sides of the bracket 201, and side blocks 2012 are fixedly connected to both sides of the U-shaped plate 202. The two side blocks 2012 are slidably connected to the two side grooves 205 respectively. When the U-shaped plate 202 is raised or lowered, the two side blocks 2012 are driven to slide along the two side grooves 205 respectively, thereby guiding the U-shaped plate 202 and ensuring the stability of the U-shaped plate 202 during movement.

[0032] First, the photovoltaic cable is passed between the driven wheel 5 and the driving wheel 6. Then, the photovoltaic cable is passed around the top of the tension roller 204 and the bottom of the two guide rollers 2013. At this time, the tension of the photovoltaic cable acts on the tension roller 204 and is transmitted to the tension sensors 2015 on both sides through the bearing 2014. The two tension sensors 2015 collect the tension signal in real time and feed it back to the controller. The controller compares the detected tension with the preset threshold and adjusts the operation of the regulating motor 209 according to the deviation signal.

[0033] When the regulating motor 209 starts, it drives the regulating shaft 2011 to rotate, and drives the bidirectional lead screw 2018 and the support shaft 2017 to rotate. Then, it drives the two lead screw nuts 2021 to slide along the cross bar 2019. Then, through the two movable rods 2020, it drives the lifting plate 2016 to slide along the two inner rods 2022, thereby realizing the lifting of the U-shaped frame 2023 and the tension roller 204.

[0034] When the adjusting shaft 2011 rotates, it drives the turntable 2010 to rotate. The adjusting rod 208 drives the U-shaped plate 202 to slide along the connecting column 206 and moves the U-shaped plate 202, thereby raising and lowering the two guide rollers 2013. This changes the distance between the two guide rollers 2013 and the tension roller 204, and finally achieves adaptive adjustment and control of the photovoltaic cable tension.

[0035] In Example 3, based on Example 1, the traction mechanism 3 includes a second bracket 301 fixed to the top of the base 1. The second bracket 301 and the first bracket 201 are arranged parallel to each other. The driving wheel 6 is rotatably connected to the inner side of the second bracket 301. One end of the driving wheel 6 extends to the outer side of the second bracket 301 and is fixedly connected to a drive motor 303. A base 302 is fixedly installed on the drive motor 303. The base 302 is fixed to the outer side of the second bracket 301. A U-shaped rod 306 is fixedly connected to the top of the second bracket 301. A top plate 305 is fixedly sleeved on the middle of the outer side of the U-shaped rod 306. An electric push rod 304 is fixedly installed at the bottom of the top plate 305. A lifting frame 307 is fixedly connected to the output end of the electric push rod 304. The lifting frame 307 is movably sleeved on the outer side of the U-shaped rod 306. The driven wheel 5 is rotatably connected to the inner side of the lifting frame 307. A V-shaped groove is provided in the middle of both the driven wheel 5 and the driving wheel 6 for positioning the photovoltaic cable.

[0036] First, start the electric push rod 304, which drives the lifting frame 307 to slide down along the U-shaped rod 306. At the same time, the driven wheel 5 descends, limiting the photovoltaic cable between the two V-shaped grooves. Then, start the drive motor 303, which drives the drive wheel 6 to rotate, and finally realizes the traction and transportation of the photovoltaic cable.

[0037] In Example 4, based on Example 1, the limiting mechanism 4 includes two guide rods 401 symmetrically fixed to the top of the U-shaped plate 202. Two guide frames 406 are symmetrically and movably sleeved on the outer side of the guide rods 401. Limiting rollers 402 are rotatably connected to the inner side of the two guide frames 406. A support wheel 405 is provided at the bottom of the guide frame 406. The support wheel 405 is located at the top of the U-shaped plate 202 and is used to support the guide frame 406 to ensure the stability of the guide frame 406 when sliding along the guide rods 401. A sleeve block 404 located between the two guide frames 406 is fixedly sleeved on the middle of the outer side of the guide rods 401. The sleeve block 404 is fixed to the top of the U-shaped plate 202. Springs 403 are fixedly connected between the two guide frames 406 and the sleeve block 404. The two springs 403 are sleeved on the outer side of the guide rods 401.

[0038] First, the photovoltaic cable is passed between the two limiting rollers 402. The two limiting rollers 402 are pushed so that the two guide frames 406 slide along the guide rod 401 and move away from each other. At this time, the two springs 403 are deformed. Under the action of the elastic force of the two springs 403, the two limiting rollers 402 are in close contact with the photovoltaic cable, thereby limiting the photovoltaic cable and preventing the photovoltaic cable from deviating during the transportation process.
