Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module processing equipment, specifically to a busbar and separator handling device. Background Technology

[0002] With social development and technological advancements, photovoltaic power generation is playing an increasingly important role in the power supply system. For photovoltaic power generation equipment, solar cells are a crucial component. In the production process of photovoltaic modules, multiple solar cells need to be connected in series to form a cell string, and multiple cell strings are connected through busbars to form a cell array. In order to prevent short circuits between busbars, isolation strips are needed to isolate the busbars and improve product yield.

[0003] In the existing equipment production process, after the busbars and isolation strips are cut, they need to be manually transported to the welding point. This not only leads to high labor costs and makes it difficult to improve welding efficiency, but also affects the product yield due to the operator's condition. Utility Model Content

[0004] To address the problem of poor welding rates caused by operators moving busbars and separators to welding points, this invention proposes a device for transporting busbars and separators; the specific solution is as follows: Specifically, it includes a suction device and a positioning platform. The suction device is set above the positioning platform and uses the positioning platform to suction the busbar and the isolation strip. The suction device includes a servo drive module, a guide mechanism, and an adsorption component. The guide mechanism is movably connected to the bottom of the servo drive and the top of the adsorption component, respectively. The guide mechanism guides the adsorption component, and the servo drive module drives the adsorption component to suction the busbar and the isolation strip.

[0005] By setting a guiding mechanism to guide the adsorption component, a precise and stable motion path is ensured when the adsorption component picks up the busbar and the isolation strip. The servo drive module drives the adsorption component to pick up the busbar and the isolation strip simultaneously, increasing the operating efficiency of the equipment and solving the problem of poor welding at the points where operators handle the busbar and the isolation strip in the existing technology.

[0006] The guiding mechanism includes a guide post, a guide sleeve, a nut, and a guiding platform. The guide post passes through the guide sleeve and is symmetrically arranged at both ends of the nut. A lead screw is also provided in the center of the nut. The lead screw passes through the nut to the adsorption assembly. The guide post is arranged parallel to the lead screw and passes through the guiding platform.

[0007] By setting a lead screw that passes through the nut to the adsorption assembly, the lead screw rotates and moves up and down within the nut, thereby raising and lowering the adsorption assembly; the guide column is stably supported by the guide sleeve, reducing the deviation of the running trajectory and ensuring the accuracy of the guide column's guidance.

[0008] Furthermore, it also includes a transport frame, which is set above the positioning platform and connected to the suction device. The guide platform is also equipped with a slider, which is movably connected to the transport frame via a slide rail. The transport frame is equipped with a cylinder, which is fixedly connected to the slider.

[0009] The conveyor is set above the positioning platform and connected to the suction device. The slider is connected to the conveyor via a slide rail. After the adsorption component picks up the manifold and the isolation strip, it is transported to the welding station by the conveyor, which increases the welding efficiency of the equipment.

[0010] Specifically, the guide column and the upper end of the lead screw are connected to the servo drive module. The servo drive module includes a servo motor, a lead screw, a coupling, and a receiving base. The receiving base is fixedly connected to the bottom of the motor. The two ends of the coupling are respectively connected to the output end of the servo motor and the input end of the lead screw. The servo motor drives the lead screw to rotate through the coupling. The connection between the coupling and the output end of the servo motor passes through the top of the receiving base, and the connection between the bottom of the coupling and the input end of the lead screw passes through the bottom of the receiving base.

[0011] By setting a base and fixing it to the bottom of the servo motor to support the motor and ensure its stable operation, and by setting a coupling to connect to the output end of the servo motor to reduce vibration during motor operation, the motor's service life can be extended and the vibration of the lead screw can be buffered. The servo motor drives the lead screw to rotate through the coupling, thereby realizing the upward or downward movement of the adsorption component, thus enabling the adsorption component to pick up the positioning platform busbar and isolation bar, increasing welding efficiency.

[0012] Preferably, the lower ends of the guide post and the lead screw are connected to the adsorption assembly. The adsorption assembly includes an adsorption head, a base, and a connecting block. The adsorption head matrix is ​​vertically arranged below the base. The guide post and the lead screw are connected to the base. The lead screw passes through the connecting block and is connected to the base.

[0013] By setting the suction head vertically below the base, the accuracy of suctioning the manifold and isolation strip is achieved. By setting the lead screw to connect to the base through the connecting block, the stability of the suction head in suctioning the manifold and isolation strip is increased.

[0014] Specifically, the positioning platform includes a support platform and a lifting cylinder. The support platform is placed above the lifting cylinder. The support platform is provided with adjacent limiting shafts to form a limiting channel to accommodate the confluence bar and the isolation bar. The limiting shafts are detachable and the limiting distance is adjustable.

[0015] By setting up a lifting and lowering air-driven support platform, the suction head's suction efficiency for manifolds and isolation strips is improved. The support platform can adjust the adjacent distance according to the size of the manifolds and isolation strips. By setting adjacent limiting shafts to form a limiting channel to accommodate the manifolds and isolation strips, the safe suction range of the suction head is limited, avoiding equipment damage and improving efficiency.

[0016] Preferably, the system further includes a clamping mechanism disposed on an adjacent side of the positioning platform. The clamping mechanism includes an upper clamping head and a lower clamping head that can be opened and closed relative to each other, a power source, and a linear module. The output end of the power source is movably connected to the upper clamping head, the lower clamping head is connected to a movable block, and the bottom of the upper clamping head is movably connected to the top of the lower clamping head. The power source drives the upper clamping head to move away from or close to the lower clamping head, and the clamping mechanism moves linearly along the linear module via the movable block.

[0017] By setting up a clamping mechanism to clamp the busbar and the isolating strip, the busbar and the isolating strip are moved to the positioning platform through a linear module, thereby increasing the welding efficiency of the busbar and the isolating strip.

[0018] Preferably, the positioning platform also includes an adsorption hole and an air pipe connector. The adsorption hole is located in two adjacent limiting shaft channels. The adsorption hole draws in the manifold strip and the isolation strip through the air pipe connector.

[0019] By setting up an adsorption hole to connect the air pipe connector, the manifold and the isolation strip are aspirated and adsorbed. This prevents the manifold and isolation strip from being unstable due to the large buoyancy of the air, which would affect the suction head's ability to pick up the material and thus affect the welding efficiency.

[0020] The adsorption assembly picks up the busbars and separators by means of a servo motor driving a lead screw via a coupling; guide posts direct the suction head to a preset distance for picking up the busbars and separators, increasing the accuracy of the suction head; a cylinder drives a slider to move up and down along a slide rail, allowing the carrying platform to deliver the busbars and separators to the corresponding position on the suction head, increasing the suction efficiency; adjacent limiting shafts form a limiting channel to accommodate the busbars and separators, limiting the safe suction range of the suction head and preventing equipment damage; and a clamping mechanism clamps the busbars and separators to the positioning platform, increasing the welding efficiency of the busbars and separators.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] This utility model proposes a busbar and separator transport device, including a suction device and a positioning platform. The suction device is vertically arranged above the positioning platform, which is used to place the cut busbar and separator. The suction device picks up the busbar and separator through the positioning platform. The suction device includes a servo drive module, a guide mechanism, and an adsorption component. The guide mechanism and the servo drive module are movably connected to the adsorption component through a lead screw 014. The guide mechanism guides the adsorption component to a preset position to prevent the adsorption component from picking up the busbar and separator outside a safe distance. The servo drive module drives the adsorption component to pick up the busbar and separator. The adsorption component picks up the busbar and separator to the welding station through the positioning platform.

[0025] By setting a guiding mechanism to guide the adsorption component, a precise and stable motion path is ensured when the adsorption component picks up the busbar and the isolation strip. The servo drive module drives the adsorption component to pick up the busbar and the isolation strip simultaneously, increasing the operating efficiency of the equipment and solving the problem of poor welding at the points where operators handle the busbar and the isolation strip in the existing technology.

[0026] In this utility model, the guiding mechanism includes a guide post 013, a guide sleeve 016, a nut 015, and a guiding platform 017. The guide sleeve 016 is fixed on the guide post 013, and the guide post 013 passes through the guide sleeve 016. The guide sleeve 016 can reduce the wear of the guide post 013 during operation. The guide post 013 is symmetrically arranged at both ends of the nut 015. A lead screw 014 is also provided in the center of the nut 015. The lead screw 014 is connected to the nut 015 by a thread, and the nut 015 is fixed on the guiding platform 17. The lead screw 014 passes through the nut 015 to the adsorption assembly. The guide post 013 is arranged parallel to the lead screw 014 and passes through the guiding platform 017.

[0027] The guide platform 017 is equipped with a slider 018, which is connected to the transport frame 002 via a slide rail 003. The transport frame 002 has vertical columns 008 on both sides, which are connected by a crossbeam. The crossbeam passes through the guide platform 017 and is connected to the guide platform 017 via a support plate 012. A slide rail 003 is located below the crossbeam, and a cylinder is located above the crossbeam. The cylinder piston 004 is placed above the guide platform 017. The cylinder barrel 005 is equipped with a left speed control valve 006 and a right speed control valve 007. When the left speed control valve 006 is turned to allow air in, the cylinder piston 004 enters the cylinder barrel, and the slider 018 moves on the transport frame via the slide rail 003, thereby enabling the adsorption component to pick up the manifold and the isolation strip to the welding station. Furthermore, when the right speed control valve is turned to allow air in, the cylinder piston 004 moves out of the cylinder barrel 005, thereby enabling the adsorption component to return to the pick-up station.

[0028] To address the drawbacks of traditional manual handling of the manifold and separator strips, this embodiment includes a servo drive module. The servo drive module comprises a servo motor 001, a lead screw 014, and a coupling 010. The coupling 010 is connected to the output end of the servo motor 001 and the input end of the lead screw 014, respectively. The servo motor 001 drives the lead screw 014 to rotate and lift through the coupling 010, thereby enabling the adsorption assembly to pick up and transport the manifold and separator strips.

[0029] By setting a lead screw 014 through a nut 015 to the adsorption assembly, and since the guide platform is connected to the slide rail 003 on the transport frame 002 via a slider 018, the guide platform 017 can move along the slide rail 003. Therefore, the nut 015 cannot move up or down. When the lead screw 014 rotates, since the nut 015 is fixed on the guide platform 017, the lead screw 014 will move back and forth inside the nut 015, thereby realizing the rise and fall of the adsorption assembly. The guide column 013 is stably supported by the guide sleeve 016, reducing the deviation of the running trajectory and ensuring the accuracy of the guide column 013.

[0030] To increase the stability of the servo motor 001, a support base 009 is provided at the bottom of the servo motor 001. The bottom of the support base 009 is fixedly connected to the bottom of the servo motor 001 and one end of the coupling 010. The bottom of the support base 009 is connected to the input end of the lead screw 014 and the other end of the coupling 010 through a fixing block 011.

[0031] By setting a support base 009 and a fixed connection to the bottom of the servo motor 001, the servo motor 001 is supported to ensure its stable operation. By setting a coupling 010 and connecting it to the output end of the servo motor 001, the servo motor 001 is damped and its vibration reduced during operation. This not only extends the service life of the servo motor 001 but also buffers the vibration of the lead screw 014 caused by the servo motor 001. The servo motor 001 drives the lead screw 014 to rotate and lift through the coupling 010, thereby enabling the adsorption component to pick up the positioning platform busbars and isolation strips, increasing welding efficiency.

[0032] The guide post 013 and the lower end of the lead screw 014 are connected to the adsorption assembly. The adsorption assembly includes an adsorption head 022, a base 021, and a connecting block 019. In order to ensure the accuracy of adsorption of the manifold and the isolation strip, the adsorption head 022 is arranged vertically below the base 021. The guide post 013 and the lead screw 014 are connected to the upper part of the base 021. The lead screw 014 passes through the connecting block 019 and is connected to the base 021.

[0033] The suction head 022 is positioned vertically below the base 021 to ensure accurate suction of the manifold and isolation strip. The lead screw 014 is connected to the base 021 via the connecting block 019, which increases the stability of the suction head 022 during the suction of the manifold and isolation strip.

[0034] To more accurately pick up the busbars and isolation strips, this utility model also includes a positioning platform. The positioning platform includes a support platform 024, a lifting cylinder 027, a slider 018, and a slide rail 003 connected to the slider 018. To fix the picking position of the busbars and isolation strips, the support platform 024 is provided with a limiting channel composed of adjacent limiting shafts 025 to accommodate the busbars and isolation strips. The lifting cylinder 027 is located below the support platform 024. The lifting cylinder 027 drives the support platform 024 to move linearly in the vertical direction through the slider 018 to avoid collisions with other mechanisms when handling the cut busbars and isolation strips. To accommodate busbars and isolation strips of different sizes, the limiting shafts 025 on the support platform 024 can be detached and the limiting distance can be adjusted. According to the different sizes of the busbars and isolation strips, the limiting shafts 025 can be manually pushed to the appropriate position to place the busbars and isolation strips and check the accuracy of movement. After checking that there are no errors, tighten all fixing screws.

[0035] The lifting cylinder 027 drives the slide rail 003 and slider 018 to lift and lower, thereby achieving the lifting and lowering movement of the support platform 024. This prevents the support platform 024 from colliding with other mechanisms when handling the cut busbars and isolation strips, thus avoiding damage to the equipment. The support platform 024 can adjust the adjacent distance according to the size of the busbars and isolation strips, saving equipment costs while improving handling efficiency. Adjacent limit shafts 025 are set to form a limit channel to accommodate the busbars and isolation strips, limiting the safe suction range of the suction head 022 and preventing equipment damage.

[0036] This embodiment also includes a clamping mechanism, which is located on one side adjacent to the positioning platform. The clamping mechanism includes an upper clamping head 029 and a lower clamping head 030 that can be opened and closed relative to each other, a power source, and a linear module. The output end of the power source is connected to the upper clamping head 029 via a hinge, and the lower clamping head 030 is connected to the movable block 033. The tops of the upper clamping head 029 and the lower clamping head 030 are connected via a hinge. In this embodiment, the power source is driven by a cylinder 031. When the cylinder 031 drives the upper clamping head 029 to press against the lower clamping head 030, the clamping mechanism clamps the busbar and the isolation strip. When the pick-up head 029 moves away from the lower gripper head 030, the gripping mechanism releases and places the busbar and the isolation strip onto the support platform 024. The movable block 033 is placed on the linear module 028. The linear module 028 is an automated precision transmission unit that provides linear motion. Essentially, it converts the rotational motion of a servo motor or stepper motor into high-precision linear reciprocating motion through a synchronous belt or ball screw, and integrates it into a precision mechanism. Therefore, the movable block 033 moves linearly through the linear module 028, enabling the gripper head to transport the cut busbar and isolation strip onto the positioning platform.

[0037] By setting up upper gripper 029 and lower gripper 030 to grip and cut the busbar and isolation strip, the cutting strip is transported to the positioning position via linear track 028, thereby increasing the welding efficiency of the busbar and isolation strip.

[0038] The positioning platform is also equipped with an adsorption hole 023 and an air pipe connector 026. The adsorption hole 023 is located in an adjacent limiting channel. The adsorption hole 023 is used to draw in the manifold strip and the isolation strip through the air pipe connector 026.

[0039] By setting the adsorption hole 023 to connect the air pipe connector 026 to the air adsorption manifold and the isolation strip, the position of the manifold and the isolation strip is prevented from shifting during the movement of the adsorption head, thus affecting the accuracy of the adsorption.

[0040] In specific operation: Motor 031 drives the hinge connection between the upper gripping head 029 and the lower gripping head 030 to close or move away to clamp or release the busbar and the isolation strip. In this embodiment, the upper gripping head 029 and the lower gripping head 030 are called grippers. The grippers move towards the cut isolation strip and the busbar and grip the busbar and the isolation strip, that is, they move in the direction of the positioning platform. The lifting cylinder 027 controls the support platform 024 to descend, making room for the grippers. The lifting cylinder 027 controls the grippers to clamp the busbar and the isolation strip respectively. After clamping, they move backward so that the busbar and the isolation strip are respectively above the limiting channel formed by the limiting shaft 025. The lifting cylinder 027 controls the support platform 024 to rise so that the isolation strip and the busbar fall into the limiting channel formed by the limiting shaft 025. The suction hole 023 is connected to the air pipe connector 026. After ventilation, the manifold and isolation strip are adsorbed. When the servo motor 001 runs, it drives the output coupling 010 to rotate. The coupling 010 is connected to the lead screw 014, which rotates and moves upward or downward within the nut 015. The guide column 013 guides the suction head 022 to the precise suction position. The suction head 022 descends to pick up the manifold and isolation strip. When the suction head 022 rises, the piston tube of the cylinder 004 above the transport frame enters the cylinder barrel. The slider 018 moves to the welding position below the transport frame via the slide rail 003, thus realizing the suction head 022 picking up the manifold and isolation strip and transporting it to the welding position. The piston tube of the cylinder 004 moves out of the cylinder barrel 005, the slider 018 moves via the slide rail 003, and the suction head 022 moves to the top of the positioning platform. The above process is repeated.

[0041] In summary: by setting the servo motor 001 to drive the coupling 010, the lead screw 014 is made to rotate. The lead screw 014 and the nut 015 are connected by threads to realize the upward or downward movement trajectory of the lead screw 014 within the nut 015, thereby realizing the upward and downward movement of the suction head 022 to pick up the busbar and the isolation bar.

[0042] The guide post 013 assists in guiding the suction head 022 to pick up the busbar and the isolation strip, increasing the accuracy of the suction head 022 and maintaining equipment safety. The transport frame transports the busbar and the isolation strip to the welding station, solving the drawbacks of manual handling in the existing technology, improving the welding efficiency of the busbar and the isolation strip, saving manpower and equipment costs.
