Description

Technical Field

[0001] This application relates to the field of photovoltaic module production equipment, and specifically to a battery string handling mechanism. Background Art

[0002] After the battery strings are welded into strings, they need to be transported to different processing stations by a battery string handling mechanism for corresponding processing. Existing battery string handling mechanisms usually include an X-axis linear drive unit, a Z-axis linear drive unit, and a suction unit. The X-axis linear drive unit is used to drive the suction unit to translate along the X-axis direction, and the Z-axis linear drive unit is used to drive the suction unit to lift, so as to drive the suction unit to pick up the battery strings from the loading station and transport the battery strings to the processing station for processing. The existing battery string handling mechanism has a large floor space along the X-axis direction (i.e., the horizontal direction), which increases the equipment size. Summary of the Utility Model

[0003] In order to solve the above technical problems, this application provides a battery string handling mechanism, which adopts the following technical solutions:

[0004] A battery string handling mechanism includes a lifting part, a swinging part, and a suction part, wherein:

[0005] The swinging part is connected to the movable part of the lifting part, and the suction part is connected to the movable part of the swinging part;

[0006] The suction part is used to suck the battery strings, the lifting part is used to drive the suction part to lift, the swinging part is used to drive the suction part to swing, and a loading station and at least one processing station are arranged on the swinging path of the suction part;

[0007] When the suction part swings to the loading station, it picks up the battery strings from the loading station.

[0008] The battery string handling mechanism of this application drives the suction part to swing and switch between the loading station and the processing station through the swinging part, so that the suction part transports the battery strings picked up from the loading station to the processing station. Compared with the existing battery string handling mechanism, the battery string handling mechanism of this application realizes the handling of battery strings by swinging, and has a small floor space along the horizontal direction, which is beneficial to shortening the equipment size.

[0009] In some embodiments, the swinging part includes a rotation drive assembly, a rotating shaft, a first swing arm and a second swing arm, wherein: the rotation drive assembly is connected to the movable part of the lifting part, the rotating shaft is connected to the movable part of the rotation drive assembly and extends along the first horizontal direction; the upper end of the first swing arm is fixedly connected to the first end of the rotating shaft, the upper end of the second swing arm is fixedly connected to the second end of the rotating shaft, the first end of the adsorption part is rotatably connected to the lower end of the first swing arm, and the second end of the adsorption part is rotatably connected to the lower end of the second swing arm; the rotation drive assembly is used to drive the rotating shaft to rotate, and when the rotating shaft rotates, the adsorption part is driven to swing via the first swing arm and the second swing arm.

[0010] By driving the first swing arm and the second swing arm to swing synchronously through the rotating drive assembly, the adsorption part can be driven to swing and switch between the loading station and the processing station. In addition, since the two ends of the adsorption part are respectively rotatably connected to the lower ends of the first swing arm and the second swing arm, the adsorption part can produce adaptive rotation under the action of its own gravity during the swinging process, so that the adsorption part remains in a horizontal state. In this way, it can be ensured that when the adsorption part swings to the loading station, it can implement stable absorption of the battery string in a horizontal state. When swinging to the processing station, if the battery string needs to be released, the battery cell can be smoothly put down in a horizontal state.

[0011] In some embodiments, the lifting part includes a first lifting drive assembly and a second lifting drive assembly, the first end of the rotating shaft is rotatably connected to the movable part of the first lifting drive assembly, and the second end of the rotating shaft is rotatably connected to the movable part of the second lifting drive assembly, and the first lifting drive assembly and the second lifting drive assembly are configured to synchronously drive the rotating shaft to lift and lower to drive the adsorption part to lift and lower; the rotating drive assembly is arranged on the movable part of the first lifting drive assembly or the second lifting drive assembly, and is transmission-connected to the first end or the second end of the rotating shaft; or, the lifting part includes a lifting drive assembly and an adapter plate, the adapter plate is connected to the driving end of the lifting drive assembly, the rotating drive assembly is mounted on the adapter plate, and the rotating drive assembly is transmission-connected to the middle part of the rotating shaft.

[0012] By configuring the lifting portion to include a first lifting drive assembly and a second lifting drive assembly, the two ends of the rotating shaft are respectively connected to the movable parts of the first lifting drive assembly and the second lifting drive assembly, and the first lifting drive assembly and the second lifting drive assembly synchronously drive the rotating shaft to lift and lower from both ends, thereby improving the lifting stability of the rotating shaft.

[0013] By configuring the lifting part to include a lifting drive assembly and an adapter plate, and configuring the rotating drive assembly on the adapter plate, it is achieved that only one lifting drive assembly is required to drive the rotating drive assembly and the rotating shaft to lift and lower, thereby reducing the structural complexity and cost of the lifting part.

[0014] In some embodiments, the adsorption part includes a suction cup mounting plate and a plurality of suction cup assemblies. Among them, the first end of the suction cup mounting plate is rotatably connected to the lower end of the first swing arm, and the second end of the suction cup mounting plate is rotatably connected to the lower end of the second swing arm; the plurality of suction cup assemblies are arranged on the suction cup mounting plate at intervals along the length direction of the suction cup mounting plate.

[0015] By arranging the adsorption part, the two ends of the adsorption part realize the rotational connection with the lower ends of the first swing arm and the second swing arm, and ensure that the adsorption part can stably adsorb the battery string along the length direction of the battery string.

[0016] In some embodiments, the battery string handling mechanism further includes a horizontal limiting component. The horizontal limiting component includes a connecting piece and a connecting rod. Among them: the upper end of the connecting piece is hinged to the movable part of the lifting part, the lower end of the connecting piece is hinged to the first end of the connecting rod, and the second end of the connecting rod is fixedly connected to the end of the adsorption part;

[0017] The distance between the upper hinge point of the connecting piece and the central axis of the rotating shaft in the second horizontal direction is equal to the distance between the lower hinge point of the connecting piece and the rotation center of the adsorption part in the second horizontal direction, where the second horizontal direction is perpendicular to the first horizontal direction.

[0018] By setting the horizontal limiting component, the horizontal limiting of the adsorption part is realized, ensuring that the adsorption part always maintains a horizontal state during the swinging process, and avoiding the adsorption part from shaking when swinging to the loading station or the processing station.

[0019] In some embodiments, a fixing frame is arranged on the movable part of the lifting part, and the upper end of the connecting piece is hinged to the fixing frame.

[0020] By arranging the fixing frame on the movable part of the lifting part, it is convenient for the connecting piece to be hinged to the movable part of the lifting part.

[0021] In some embodiments, the connecting piece is a cylinder. The cylinder block of the cylinder is hinged to the movable part of the lifting part, and the telescopic rod of the cylinder is hinged to the first end of the connecting rod; the cylinder is configured to drive the adsorption part to flip relative to the lower ends of the first swing arm and the second swing arm.

[0022] Using the cylinder as the connecting piece, during the swinging process of the adsorption part, the extension length of the telescopic rod of the cylinder remains unchanged, thereby ensuring that the adsorption part remains horizontal during the swinging process. When the adsorption part swings to a predetermined position, such as when swinging to the detection station, the cylinder can control the telescopic rod to extend and retract, thereby driving the adsorption part to flip outward from the horizontal state to the vertical state to facilitate the detection of the battery string adsorbed on the adsorption part.

[0024] By arranging the power-on part at both ends of the adsorption part, when the adsorption part rotates to the EL detection station, the power-on part can cooperate with the EL detection device installed at the EL detection station to complete the EL detection of the battery string, thereby improving the EL detection efficiency and avoiding the additional picking and placing of the battery string caused by EL detection, which is beneficial to reducing the fragmentation rate of the battery string.

[0025] In some embodiments, the power-on part includes a first clamping part and a second clamping part, wherein: the first clamping part is arranged at the first end of the adsorption part, the first clamping part is electrically connected to the positive pole of the power supply, and the first clamping part is configured to clamp the extended welding tape at the first end of the battery string; the second clamping part is arranged at the second end of the adsorption part, the second clamping part is electrically connected to the negative pole of the power supply, and the second clamping part is configured to clamp the extended welding tape at the second end of the battery string.

[0026] A power-on part with a simple structure is provided. After the second handling mechanism picks up the battery string, the first clamping part and the second clamping part respectively clamp the extended welding tapes at both ends of the battery string, and then the battery string can be powered on.

[0027] In some embodiments, a blanking station is further arranged on the swinging path of the adsorption part; when the adsorption part swings to the blanking station, the adsorption part releases the battery string.

[0028] The automatic blanking of the processed battery string is realized. Description of the Drawings

[0039] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0040] As shown in Figures 1 to 4 the figure, the battery string handling mechanism of the present application includes a lifting part 1, a swinging part 2 and an adsorption part 3, wherein:

[0041] The swinging part 2 is connected to the moving part of the lifting part 1, and the adsorption part 3 is connected to the moving part of the swinging part 3.

[0042] The adsorption part 3 is used for adsorbing the battery string, the lifting part 1 is used for driving the adsorption part 3 to lift, the swinging part 2 is used for driving the adsorption part 3 to swing, and a loading station and at least one processing station are arranged on the swinging path of the adsorption part 3.

[0043] When the adsorption part 3 swings to the loading station, it sucks the battery string from the loading station.

[0044] In the battery string handling mechanism of the embodiment of the present application, the swinging part 2 drives the adsorption part 3 to swing and switch between the loading station and the processing station, so that the adsorption part 3 transports the battery string sucked from the loading station to the processing station. Compared with the existing battery string handling mechanism, the battery string handling mechanism in the embodiment of the present application realizes the handling of the battery string by swinging, and has a small floor space in the horizontal direction (such as the Y direction in 1), which is beneficial to shortening the size of the equipment in the horizontal direction.

[0045] As Figures 1 to 4As shown, optionally, the swing part 2 includes a rotation drive assembly 21, a rotating shaft 22, a first swing arm 23 and a second swing arm 24, wherein: the rotation drive assembly 21 is connected to the movable part of the lifting part 1, and the rotating shaft 22 is connected to the movable part of the rotation drive assembly 21, and extends along the first horizontal direction (such as the X-axis direction). The upper end of the first swing arm 23 is fixedly connected to the first end of the rotating shaft 22, and the upper end of the second swing arm 24 is fixedly connected to the second end of the rotating shaft 22. The first end of the adsorption part 3 is rotatably connected to the lower end of the first swing arm 23, and the second end of the adsorption part 3 is rotatably connected to the lower end of the second swing arm 24. The rotation drive assembly 21 is used to drive the rotating shaft 22 to rotate, and when the rotating shaft 22 rotates, the adsorption part is driven to swing through the first swing arm 23 and the second swing arm 24.

[0046] By driving the first swing arm 23 and the second swing arm 24 to swing synchronously through the rotating drive assembly 21, the adsorption part 3 can be driven to swing and switch between the loading station and the processing station. In addition, since the two ends of the adsorption part 3 are respectively rotatably connected to the lower ends of the first swing arm 23 and the second swing arm 24, the adsorption part 3 can produce adaptive rotation under the action of its own gravity during the swinging process, so that the adsorption part 3 can maintain a horizontal state during the swinging process. In this way, it can be ensured that when the adsorption part 3 swings to the loading station, it can implement stable absorption of the battery string in a horizontal state. When swinging to the processing station, if the battery string needs to be released, the battery cell can be smoothly put down in a horizontal state.

[0047] Optionally, the lifting part 1 includes a first lifting drive assembly 11 and a second lifting drive assembly 12, the first end of the rotating shaft 22 is rotatably connected to the movable part of the first lifting drive assembly 11, the second end of the rotating shaft 22 is rotatably connected to the movable part of the second lifting drive assembly 12, and the first lifting drive assembly 11 and the second lifting drive assembly 12 are configured to synchronously drive the rotating shaft 22 to rise and fall, so as to drive the adsorption part 3 to rise and fall. The rotating drive assembly 21 is arranged on the movable part of the first lifting drive assembly 11 or the second lifting drive assembly 12, and is drivingly connected to the first end or the second end of the rotating shaft 22.

[0048] The two ends of the rotating shaft 22 are respectively connected to the movable parts of the first lifting drive assembly 11 and the second lifting drive assembly 12. The first lifting drive assembly 11 and the second lifting drive assembly 12 can synchronously drive the rotating shaft 22 to rise and fall from both ends, thereby improving the lifting stability of the rotating shaft and ultimately improving the lifting stability of the adsorption part 3.

[0049] In another embodiment, the lifting part 1 includes a lifting drive assembly and an adapter plate, wherein the adapter plate is connected to the driving end of the lifting drive assembly, the rotating drive assembly 21 is installed on the adapter plate, and the rotating drive assembly 21 is connected to the middle of the rotating shaft 22 by transmission.

[0050] With such a setting, only one lifting drive assembly needs to be set, which can drive the rotation drive assembly 21 and the rotating shaft 22 to lift, thereby reducing the structural complexity and cost of the lifting part 1.

[0051] Optionally, the adsorption part 3 includes a suction cup mounting plate 31 and a plurality of suction cup assemblies 32. Among them, the first end of the suction cup mounting plate 31 is rotatably connected to the lower end of the first swing arm 23, and the second end of the suction cup mounting plate 31 is rotatably connected to the lower end of the second swing arm 24. The plurality of suction cup assemblies 32 are arranged on the suction cup mounting plate 31 at intervals along the length direction of the suction cup mounting plate 31 (i.e., the first horizontal direction).

[0052] Optionally, the battery string handling mechanism in the embodiment of the present application further includes a horizontal limiting assembly 4. The horizontal limiting assembly 4 includes a connecting member 42 and a connecting rod 43. Among them: the upper end of the connecting member 42 is hinged to the movable part of the lifting part 1, the lower end of the connecting member 42 is hinged to the first end of the connecting rod 43, and the second end of the connecting rod 43 is fixedly connected to the end of the adsorption part 3. The distance a between the upper hinge point of the connecting member 42 and the central axis of the rotating shaft 22 in the second horizontal direction is equal to the distance b between the lower hinge point of the connecting member 42 and the rotation center of the adsorption part 3 in the second horizontal direction, where the second horizontal direction is perpendicular to the first horizontal direction. For example, the second horizontal direction is the Y-axis direction.

[0053] Since both ends of the adsorption part 3 are rotatably connected to the lower ends of the first swing arm 23 and the second swing arm 24, during the process of the rotation drive assembly 21 driving the first swing arm 23 and the second swing arm 24 to swing, the horizontal limiting assembly 4 realizes the horizontal limiting of the adsorption part 3, so that the adsorption part 3 always maintains a horizontal state during the swinging process, avoiding the adsorption part 3 from shaking when swinging to the loading station or the processing station.

[0054] In order to facilitate the hinging of the connecting member 42 and the movable part of the lifting part 1, a fixing frame 41 is provided on the movable part of the lifting part 1, and the upper end of the connecting member 42 is hinged to the fixing frame 41.

[0055] Optionally, the connecting member 42 is a cylinder. The cylinder block of the cylinder is hinged to the movable part of the lifting part 1, and the telescopic rod of the cylinder is hinged to the first end of the connecting rod 43. The cylinder is configured to drive the adsorption part 3 to flip relative to the lower ends of the first swing arm 23 and the second swing arm 24.

[0056] Using a cylinder as the connecting member 42, during the swinging process of the adsorption part 3, the extending length of the telescopic rod of the cylinder remains unchanged, thereby ensuring that the adsorption part 3 remains horizontal during the swinging process. When the adsorption part 3 swings to a predetermined position, for example, when swinging to the detection station, the telescopic rod of the cylinder expands and contracts, thereby driving the adsorption part 3 to flip outward from the horizontal state, such as flipping to a vertical state facing the outside, so as to facilitate the detection of the battery string adsorbed on the adsorption part 3.

[0057] As shown Figures 1 to 4 As shown, optionally, the processing stations on the swinging path of the adsorption part 3 include an EL detection station. The battery string handling mechanism in the embodiment of the present application further includes a power-on part 5. The power-on part 5 is arranged at both ends of the adsorption part 3. When the adsorption part 3 swings to the EL detection station, the power-on part 5 is configured to power on the battery string adsorbed on the adsorption part 3.

[0058] By arranging the power-on part 5 at both ends of the adsorption part 3, when the adsorption part 3 rotates to the EL detection station, the power-on part 5 can cooperate with the EL detection camera installed at the EL detection station to complete the EL detection of the battery string, thereby improving the EL detection efficiency. In addition, during the EL detection process, there is no need to release the battery string onto the detection table, thereby avoiding the additional grasping and placing of the battery string caused by the EL detection, which is beneficial to reducing the fragmentation rate of the battery chips.

[0059] Optionally, the power-on part 5 includes a first clamping part 51 and a second clamping part 52, where: the first clamping part 51 is arranged at the first end of the adsorption part 3, the first clamping part 51 is electrically connected to the positive pole of the power supply, and the first clamping part 51 is configured to clamp the extended welding tape at the first end of the battery string. The second clamping part 52 is arranged at the second end of the adsorption part, the second clamping part 52 is electrically connected to the negative pole of the power supply, and the second clamping part 52 is configured to clamp the extended welding tape at the second end of the battery string.

[0060] After the adsorption part 3 adsorbs the battery string, the first clamping part 51 and the second clamping part 52 can respectively clamp the extended welding tapes at both ends of the battery string, so that the power supply can power on the battery string.

[0061] Optionally, a blanking station is also arranged on the swinging path of the adsorption part 3. When the adsorption part 3 swings to the blanking station, the adsorption part 3 releases the battery string, thereby realizing the automatic blanking of the processed battery string.
