Description
Technical Field
[0001] This utility model relates to the field of busbar feeding, and in particular to a busbar feeding pressing device and busbar feeding tooling. Background Technology
[0002] Busbars, also known as busbar ribbons, are key conductive materials in photovoltaic module manufacturing. They are primarily used to connect cell strings to junction boxes, enabling current collection and transmission. The core function of busbars is to connect cell strings in series and transmit current to the junction box, directly affecting the module's output power and circuit stability. In shingled modules, they completely replace interconnecting strips, undertaking all current collection functions.
[0003] However, in the manufacturing process of existing solar panels, when the busbars are being fed and welded to the photovoltaic panels, the subsequent busbars need to be pressed against each other to prevent them from slipping off. However, the existing pressing mechanism usually uses a pressing block to press multiple busbars being fed at the same time. However, due to the differences in the size and width of the busbars, the pressing block will tilt left and right during the pressing process, which cannot guarantee stable pressing of all busbars and may even cause some busbars to slip off, which is very inconvenient. Summary of the Invention
[0004] The first objective of this invention is to provide a pressing device for feeding busbars. The device features an ingenious structure, employing multiple pressing blocks and a pressing rod that slides against a pressing base, along with a continuous force applied by a return spring, to ensure proper feeding.
[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a pressing bracket and a pressing platform fixedly mounted on the pressing bracket; the pressing bracket is provided with a pressing assembly for pressing the busbar against the pressing platform, the pressing assembly includes a pressing cylinder mounted on the pressing bracket, a first lifting bracket fixed to the telescopic end of the pressing cylinder, a pressing base plate mounted on the first lifting bracket, and a plurality of pressing components evenly arranged on the pressing base plate along the extending direction of the pressing base plate, the pressing assembly includes two pressing bases disposed opposite to each other on the bottom surface of the pressing base plate, a pressing rod slidably mounted on the pressing base, a return spring sleeved on each pressing rod, and a pressing block, the pressing base plate... The device has through holes corresponding to each pressure rod and allowing the pressure rods to pass through. Each through hole corresponds to a pressure base. Each pressure base has a sliding groove that corresponds to and is coaxial with each through hole. The upper end of each pressure rod is slidably connected in the sliding groove and the corresponding through hole. The lower end of each pressure rod is mounted on a pressure block. Each pressure block has a docking block and a docking slot on both sides. The pressure blocks on adjacent pressure components are adjacent to each other through the docking block and the docking slot. Each pressure block is pressed against the pressure platform by the driving of the pressure cylinder on the first lifting bracket, the sliding engagement of each pressure rod with the corresponding pressure base, and the continuous force of the return spring.
[0006] Furthermore, the aforementioned pressing bracket is equipped with two pressing cylinders, and first lifting brackets are installed on both sides of the pressing base plate. The telescopic ends of each pressing cylinder are fixed on the corresponding first lifting bracket. The pressing bracket has vertically arranged first side slide rails on both sides, and each first lifting bracket has a first side slider that is adapted to each first side slide rail. The pressing base plate is connected to the pressing bracket by the driving of the first lifting brackets by each pressing cylinder and the lifting and lowering of each first side slide rail and the first side slider.
[0007] Furthermore, the aforementioned pressure belt support is also equipped with a limiting frame that can limit the lifting and lowering of the pressure base plate. The limiting frame includes multiple pressure belt rods mounted on the pressure belt support and limiting blocks disposed below each pressure belt rod. A connecting plate parallel to the pressure base plate is also provided above the pressure belt support. Each pressure belt rod is mounted on the connecting plate. Each limiting block presses against the upper surface of the pressure base plate during the lifting process, thereby limiting the lifting of the pressure base plate.
[0008] The second objective of this invention is to provide a busbar feeding fixture with an ingenious structure that enables quick and stable adjustment, bending, and flux application of the busbar, making it convenient and practical.
[0009] The technical solution to achieve the purpose of this utility model is as follows: This utility model has parallelly arranged base blocks, a mounting base plate, a first motor mounted on the mounting base plate, and an adjusting base plate slidably mounted on each base block under the drive of the first motor. The adjusting base plate is provided with guide rollers for guiding the feeding of the confluence belt, two confluence belt feeding pressing devices, and a bending assembly. The bending assembly is arranged between the two confluence belt feeding pressing devices. The bending assembly includes a bending bracket mounted on the adjusting platform, multiple bending cylinders mounted on the bending bracket, a second lifting bracket mounted on the telescopic end of each bending cylinder, and a bracket fixed to each second lifting bracket. The bending bracket has a lower pressure plate, a lower pressure block on the lower pressure plate, and an upper pressure block on the bending bracket. The bending bracket has a second side slide rail on both sides. Each second lifting bracket has a second side slider that matches the second side slide rail. Each second lifting bracket is slidably connected to the bending bracket through the cooperation of the second side slide rail and the second side slider. Both the upper pressure block and the lower pressure block have bending steps, and the bending steps on the upper pressure block and the lower pressure block are arranged opposite to each other. The lower pressure block drives the second lifting bracket through each bending cylinder to press and bend the confluence between the upper pressure block and the lower pressure block against the upper pressure block.
[0010] Furthermore, each pressing bracket and bending bracket is provided with a bottom slider at its bottom, and the adjusting base plate is provided with multiple parallel bottom slide rails. The extension direction of each bottom slide rail is perpendicular to the sliding direction of the adjusting base plate. Each pressing bracket and bending bracket is slidably connected to the adjusting base plate through the cooperation of each bottom slider and bottom slide rail.
[0011] Furthermore, the aforementioned adjusting base plate is also equipped with a coating assembly for applying flux to the busbar. The coating assembly is disposed between the guide roller and the pressure belt support near the guide roller. The coating assembly includes a coating support, a coating box disposed on the coating support and through which the busbar can pass, multiple coating rollers rotatably disposed within the coating box, and multiple feed pipes disposed above the coating box and used for adding flux. The rotation axis of the coating rollers is perpendicular to the bottom slide rail. The guide roller guides the busbar into the coating box, and each coating roller applies flux to the busbar entering the coating box and then discharges the busbar.
[0012] Furthermore, each pressure band support is equipped with a residual liquid box for collecting residual flux liquid.
[0013] This utility model has positive effects: (1) By setting a pressing component on the pressing platform, the pressing cylinder drives the first lifting bracket to lift and lower. At the same time, the first lifting bracket drives the pressing base plate and the pressing components at the bottom of the pressing base plate to press the busbar. During the pressing process of each pressing block, each pressing block presses the busbar on the pressing platform through the driving of the pressing cylinder to the first lifting bracket, the sliding cooperation between each pressing rod and the corresponding pressing base, and the continuous force of the reset spring. This effectively solves the problem of unstable pressing caused by a single pressing block pressing the busbar in the prior art. Through multiple pressing blocks and the continuous force of the reset spring, it can be ensured that each busbar can be pressed stably and firmly, avoiding the occurrence of tape slippage. This ensures the stability of the busbar feeding process and the stability of the subsequent welding process between the busbar and the battery cell. The structure is ingenious, stable and practical.
[0014] (2) This utility model provides a first side slide rail on the pressing bracket and a first side slider on the first lifting bracket. The first lifting bracket is lifted and slidably connected to the pressing bracket through the cooperation of each first side slider and the first side slide rail, which effectively ensures the stability of the first lifting bracket moving on the pressing bracket. It is convenient and practical.
[0015] (3) This utility model sets a limiting frame on the pressing bracket and sets the limiting frame as a connection of multiple pressing rods and limiting blocks. When the pressing base plate rises, the limiting blocks press and limit the rising process, thus avoiding excessive lifting of the first lifting bracket and impact on the pressing bracket. It is safe and practical.
[0016] (4) By setting a bending component on the adjusting base plate, during the feeding process of the busbar, the lower pressing block drives the second lifting bracket through each bending cylinder to press and bend the busbar located between the upper pressing block and the lower pressing block, which effectively lays the foundation for the subsequent stacking and welding of the busbar and the battery cell, ensuring the high efficiency of bending and the accuracy of subsequent welding of the busbar and the battery cell, which is efficient and convenient.
[0017] (5) This utility model sets bottom sliders at the bottom of each pressing bracket and bending bracket, and sets corresponding bottom slide rails on the adjusting base plate. The first motor drives the adjusting base plate to make precise adjustments to the pressing and bending components, ensuring the accuracy of busbar feeding and preventing the busbar from shifting from the battery cells during feeding. At the same time, the bottom sliders and bottom slide rails can be used to adjust the distance between each pressing component and bending component, thereby ensuring that the busbar will not jam or retract during feeding and bending. It can also meet different usage spaces and adapt to different usage environments, making it convenient and efficient.
[0018] (6) This utility model provides a coating component on the adjustment base plate. The coating roller can uniformly and comprehensively coat each busbar with flux, thereby ensuring the high efficiency of welding and the high quality of welding between the busbar and the battery cell. It is convenient and practical.
[0019] (7) By setting a residual liquid box below the pressure belt support, this utility model can catch the residual flux liquid falling from the busbar during the feeding process, thus avoiding pollution to the processing environment and is highly efficient and practical.
