Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell technology, specifically to an adsorption-type photovoltaic cell handling fixture. Background Technology

[0002] In recent years, slicing technology and micro-pitch technology in photovoltaic modules have proven to be simple and effective in improving power generation efficiency, and their market share has been increasing year by year. However, the main processes involved in module production are...

[0003] The process involves two main steps: first, the solar cells are cut into multiple smaller solar cells; second, the smaller solar cells are wired together to form a solar cell string. After the smaller solar cells are placed in the material box, the material box containing the solar cells needs to be transported to the cell picking station by the material box feeding device. Then, the cell picking robot picks up the solar cells from the material box and loads them into the processing device.

[0004] For example, Chinese Patent Publication No. 202110766144.8, published on January 2, 2024, discloses an integrated equipment for dicing and stringing battery cells, including a dicing production line, a ribbon preparation line arranged in conjunction with the dicing production line, a stringing station connected to the ends of the dicing production line and the ribbon preparation line, a welding station connected to the end of the stringing station, a battery string EL detection station connected to the end of the welding station, and a cutting mechanism set between the welding production line and the stringing detection mechanism, which enables the equipment to operate efficiently as a whole and greatly improves production capacity.

[0005] The aforementioned literature also discloses the structure of a multi-functional robotic arm, which consists of a cell gripper assembly, a Z-axis drive mechanism for the cell gripper assembly, and several pressure fixture adsorption assemblies arranged on one side near the dicing production line. Several welding strip gripper assemblies are evenly spaced in the gaps between the pressure fixture adsorption assemblies, along with the Z-axis drive mechanism for the pressure fixture-welding strip assembly and the Y-axis drive linear motor assembly for the pressure fixture-welding strip assembly. However, due to the different positions of the cell feeding and picking station and the pressure fixture conveying station, the independently arranged cell gripper assembly and pressure fixture adsorption assembly in the aforementioned literature cannot simultaneously grip the cell and the pressure fixture. Consequently, misalignment may occur during the process of conveying the cell and the pressure fixture to the welding station, thus affecting production efficiency. Furthermore, by separately setting the grippers for the cell and the pressure fixture, the structural complexity of the entire production line is increased, and the reliability of placing the cell and the pressure fixture cannot be guaranteed. Utility Model Content

[0006] The purpose of this invention is to provide an adsorption-type photovoltaic cell handling fixture that can simultaneously transport cells and clamps, avoiding misalignment. It has a simple and reliable structure.

[0007] To achieve the above objectives, an adsorption-type photovoltaic cell handling fixture includes a robotic arm, a fixed frame, and two or more adsorption components (first and second). The robotic arm is mounted on a support base and has a connecting rod. The fixed frame includes a first fixed frame and a second fixed frame. The first fixed frame is located below the second fixed frame and is connected to the second fixed frame to form an integral unit. The connecting rod passes through the second fixed frame and is fixedly connected to the first fixed frame. The first adsorption component is connected to the bottom of the first fixed frame, and the second adsorption component is located at both ends of the second fixed frame. There is a gap between the first adsorption component and the second adsorption component.

[0008] The aforementioned structure allows the robotic arm to move the fixed frame between the cell material box conveyor line and the press conveyor line. At this point, fixed frame one is positioned above the cell material box, and fixed frame two is positioned above the press conveyor line. After the robotic arm descends to a suitable height, the actions of suction component one picking up the cell and suction component two picking up the press are performed simultaneously. There is a gap between suction component one and suction component two, ensuring that there is a gap between the cell and the press after suction, so that the cell and the press do not interfere with each other. This allows the cell and the press to be transferred to the cell welding conveyor line simultaneously, achieving synchronous transport of the cell and the press, thereby effectively avoiding misalignment that could affect subsequent cell welding processes.

[0009] Furthermore, the robotic arm includes a fixed arm, a rotating arm, and a connecting arm. The fixed arm is fixed on a support base, one end of the rotating arm is rotatably connected to the fixed arm, and the other end of the rotating arm is rotatably connected to the connecting arm. A drive motor is installed inside the connecting arm.

[0010] With the above setup, after the adsorption components 1 and 2 pick up the battery cells and the press, the connecting arm can be rotated by the rotating arm, thereby transferring the battery cells and the press to the battery cell welding conveyor line.

[0011] Furthermore, the upper end of the connecting rod is configured as a lead screw, the lower end of the connecting rod is configured as a cylinder, the lead screw nut on the connecting arm is sleeved on one end of the lead screw, the output end of the drive motor is connected to the lead screw nut through a transmission belt, the other end of the lead screw is embedded in the cylinder and rotatably connected to the cylinder, and the bottom of the cylinder is fixedly connected to the fixing frame.

[0012] The above setup allows the drive motor to rotate the lead screw nut, thereby raising and lowering the lead screw in the vertical direction. This adjusts the height of the mounting frame, enabling the first and second adsorption components on the mounting frame to pick up the battery cells and the pressure fixture, respectively.

[0013] Furthermore, a step is provided on the first fixed frame below the connection between the first fixed frame and the second fixed frame. The step is used to accommodate the pressure device sucked up by the second adsorption component.

[0014] The above configuration creates a gap between the first and second adsorption components by providing a step on the first fixing frame.

[0015] Furthermore, one side of the bottom of the fixing frame is recessed from the lower end of the fixing frame to the upper end of the fixing frame to form a step. The width of the step matches the width of the press. The adsorption component is fixedly connected to the other side of the bottom of the fixing frame, and the lower end of the adsorption component is in the same plane.

[0016] The above settings allow the suction press to be contained within the step, preventing collision between the press and the battery cell after the suction component has picked up the battery cell.

[0017] Furthermore, the two ends of the fixing frame 2 located above the step extend outward in the horizontal direction to form a fixing end, the adsorption element 2 is set on the fixing end, and a proximity sensor is provided between the adsorption elements 2, with the lower end of the adsorption element 2 and the lower end of the proximity sensor in the same plane.

[0018] The above setup allows the suction element to pick up the press, thus keeping the press perfectly still within the step. Attached Figure Description

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

[0024] like Figures 1 to 4As shown, an adsorption-type photovoltaic cell handling fixture includes a robotic arm mounted on a support base z1. The robotic arm has a connecting rod mounted at the end furthest from the support base z1. The robotic arm includes a fixed arm z2, a rotating arm z3, and a connecting arm z4. One end of the fixed arm z2 is fixed to the support base z1. One end of the rotating arm z3 is rotatably connected to the fixed arm z2, and the other end of the rotating arm z3 is rotatably connected to the connecting arm z4. A drive motor (not shown in the figure) is installed inside the connecting arm z4. In this embodiment, the upper end of the connecting rod is a lead screw z5, and the lower end of the connecting rod is a cylinder z6. A lead screw nut z7 is provided at the end of z4 away from the rotating arm z3. The output end of the drive motor is connected to the lead screw nut z7 via a transmission belt. The lead screw nut z7 is sleeved on one end of the lead screw z5. The other end of the lead screw z5 is embedded in the cylinder z6 and rotatably connected to the cylinder z6. The bottom of the cylinder z6 is fixedly connected to the first fixing frame z8. In this way, the drive motor can drive the lead screw nut z7 to rotate, thereby making the lead screw z5 rise and fall in the vertical direction, thus adjusting the height of the fixing frame. This allows the first adsorption component z11 and the second adsorption component z12 on the fixing frame to pick up the battery cell z13 and the pressure fixture z14 respectively after adjusting to a suitable height.

[0025] In this embodiment, the device also includes a fixing frame, two or more adsorption components z11 and adsorption components z12. The fixing frame includes a fixing frame z8 and a fixing frame z9. The fixing frame z8 is located below the fixing frame z9 and is connected to the fixing frame z9 to form an integral unit. The middle part of the fixing frame z9 is a hollow structure. The bottom of the cylinder z6 passes through the hollow structure of the fixing frame z9 and is fixedly connected to the fixing frame z8, so that the cylinder z6, the fixing frame z8 and the fixing frame z9 are connected to form an integral unit. A step z10 is provided on the fixing frame z8 below the connection between the fixing frame z8 and the fixing frame z9. Specifically, one side of the bottom of the fixing frame z8 is recessed from the lower end of the fixing frame towards the upper end of the fixing frame to form a step z10. The width of the step z10 matches the width of the pressure device z14. The step z10 is used to accommodate the pressure device z14 sucked up by the adsorption component z12.

[0026] like Figure 1As shown, the first adsorption element z11 is connected to the bottom of the first fixing frame z8. Specifically, the first adsorption element z11 is fixedly connected to the other side of the bottom of the first fixing frame z8, and the ends of the first adsorption element z11 are in the same plane. The second adsorption element z12 is disposed at both ends of the second fixing frame z9. The two ends of the second fixing frame z9 located above the step z10 extend outward in the horizontal direction to form fixed ends z91. The second adsorption element z12 is disposed on the fixed ends z91. In this embodiment, two adsorption elements are disposed on each fixed end z91. Two adsorption components, z12 and z12, are arranged side by side along the width of the fixing frame z9. A proximity sensor z15 is provided between the two adsorption components z12. The lower end of the adsorption component z12 and the lower end of the proximity sensor z15 are in the same plane. When the proximity sensor z15 detects the pressure, the adsorption component z12 can pick up the pressure component z14, so that the pressure component z14 just stops in the step z10. In this embodiment, the first adsorption component z11 is a vacuum suction cup and the second adsorption component z12 is an electromagnet.

[0027] In this embodiment, due to the different positions and heights of the press conveyor line and the cell box conveyor line, in order to meet the requirement of synchronously picking up the cell z13 and the press z14, the plane where the lower end of the second adsorption member z12 is located is set higher than the plane where the lower end of the first adsorption member z11 is located. The height difference between the lower end of the second adsorption member z12 and the lower end of the first adsorption member z11 matches the height difference between the press conveyor line and the cell box conveyor line, thereby achieving simultaneous picking up. After the second adsorption member z12 picks up the press z14, the press z14 is accommodated in the step z10, and the cell z13 and the press z14 do not interfere with each other after being picked up.

[0028] The working principle of this utility model is as follows: After the robotic arm rotates at different angles, the first fixing frame Z8 and the second fixing frame Z9 are positioned above the battery cell material box conveying line and the pressing board conveying line, respectively. The connecting rod is driven to descend by the drive motor set in the robotic arm. After the first adsorption component Z8 and the second adsorption component Z9 pick up the battery cell and the pressing board, the robotic arm rotates to move the battery cell and the pressing board to the welding conveying line. Then, the battery cell and the pressing board are released respectively to enter the next welding process.
