Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cell production, and in particular to a photovoltaic cell stacking material feeding device. Background Art

[0002] Photovoltaic cells are semiconductor material components that can convert sunlight into electrical energy. They convert light energy into electrical energy through the photoelectric effect, generate direct current, supply power or convert it into alternating current to meet electricity demand. Cell handling equipment is an important part of the cell manufacturing process. During the production process, cells need to be converted from a stacked state to a separated state and transported to an automatic production line. For example, conventional silicon solar cells use screen printing electrode technology. The cells received by this process are stacked and placed in a material box. Single cells need to be extracted and transported to the printing station.

[0003] The patent application document with the publication number CN109305557A discloses a feeding device for battery cell production, including a fixed seat, a vertically arranged electric telescopic rod is bolted to the middle position of the top outer wall of the fixed seat, and a lifting block with a circular cross section is bolted to the top outer wall of the electric telescopic rod, and a support seat is bolted to both sides of the top outer wall of the fixed seat, and a ventilation seat is bolted to the top outer wall of the support seat, and a ventilation hole is opened in the middle position of the top outer wall of the ventilation seat. When feeding, the electric telescopic rod pushes the top of the stacked battery cells to move to the ventilation hole, and the ventilation hole blows air toward the direction of the battery cells to form an air knife, blows up the battery cell at the top of the stacked battery cells, and then uses a vacuum suction cup to suck up the top battery cell for feeding.

[0004] However, this solution still has the following problems: as the material is continuously loaded, the pusher needs to push the stacked battery cells to gradually move upwards, but when filling, the machine needs to be stopped and the pusher needs to be reset before the material can be placed, which affects the loading efficiency. Summary of the invention

[0005] The present invention provides a photovoltaic cell stacking material feeding device, aiming to solve the problem in the related art that the machine needs to be stopped for filling, which affects the feeding efficiency.

[0006] The photovoltaic cell stacking material loading device of the present invention includes a conveying assembly and a loading assembly arranged on a frame, the loading assembly includes a lifting member and a plurality of placing members arranged on the lifting member, the lifting members are arranged in two groups at intervals, after the placing members are rotated to between the two groups of lifting members, the two placing members on the same horizontal plane form a platform for placing the cell sheets, the frame is provided with a material preparation assembly, the material preparation assembly includes a material preparation seat, a conveying member 1 and a pushing member 1, the output end of the pushing member 1 is connected to the material preparation seat for pushing the material preparation seat to the lifting member, the conveying member 1 is arranged on the material preparation seat for placing spare cell sheets, and the output end of the conveying member 1 moves between two placing members at the bottom of the lifting member to transfer the cell sheets to the placing members.

[0007] The effect is that the stacked battery cells are placed on the placement piece, the lifting piece drives the placement piece to move in the vertical direction, and the battery cells are pushed to the top of the lifting piece for loading, and at the same time, the spare battery cell materials are placed on the conveying piece 1 on the preparation seat. When preparation is needed, the pushing piece 1 drives the output end of the conveying piece 1 to move between the two placement pieces close to the bottom of the lifting piece, and then the conveying piece 1 transfers the battery cells to the placement piece for standby. After the battery cells on the top of the lifting piece are loaded, the lifting piece drives the spare battery cells to move to its top for feeding again. The above operations are repeated, and filling can be carried out without stopping the machine, thereby improving work efficiency.

[0008] Preferably, an air knife is provided on the frame near the top of the lifting member, the blowing end of the air knife is arranged toward the lifting member, a collecting frame for collecting battery cell debris is provided on the side of the lifting member facing away from the air knife, and an opening is provided on the side of the collecting frame close to the lifting member.

[0009] The effect is that the air knife blows air to the top of the battery cell, so that the battery cell is separated from the adjacent battery cell, so that the loading assembly can transfer the single battery cell to the conveying assembly. At the same time, a collection frame is arranged on the side of the lifting member and opposite to the air knife, and the opening of the collection frame is arranged toward the lifting member. When there are debris on the surface of the battery cell, the air knife blows the debris through the opening into the collection frame to process the debris, thereby reducing the phenomenon that the debris affects the subsequent processing of the battery cell.

[0010] Preferably, the collection frame and the air knife are spaced apart in the vertical direction, and the collection frame is arranged on the side of the air knife close to the ground, a mounting plate for installing the air knife is provided on the frame, the air knife is rotatably arranged on the frame, a rotating part is provided on the mounting plate, an output end of the rotating part is connected to the air knife for adjusting the angle of the air knife, the loading assembly also includes a mechanical arm, an identification part for identifying debris on the surface of the battery cell is provided on the mechanical arm, a controller is provided on the frame, the identification part is electrically connected to the controller, and the control end of the controller is connected to the switch of the rotating part.

[0011] The effect is that the robot arm is used to transfer the battery cell from the lifting member to the conveying assembly. When the robot arm transports the battery cell, the identification member identifies the debris on the surface of the battery cell. When it is identified that there is debris on the surface of the battery cell, a signal is sent to the controller. After receiving the signal, the controller controls the rotating member to work, and the rotating member drives the air knife to rotate to an inclined state toward the battery cell, so that the air knife can blow the debris on the surface of the battery cell into the collection frame.

[0012] Preferably, the placement member includes a placement seat and a second conveying member, the placement seat is connected to the lifting member, the second conveying member is arranged on the placement seat, and the conveying direction of the second conveying member is the same as the conveying direction of the first conveying member.

[0013] The effect is that a conveyor member 2 is arranged on the placement seat, and the conveying direction of the conveyor member 2 is set to be the same as the conveying direction of the conveyor member 1. When preparing materials, after the conveyor member 1 moves between the two conveyor members 2, the conveyor member 1 and the conveyor member 2 work synchronously, and the two cooperate to rotate the spare battery cell to the conveyor member 2, thereby reducing the friction force on the battery cell during the transfer process and improving the stability of the battery cell when moving.

[0014] Preferably, two sliders are provided on the placement seat for sliding along the vertical direction, and rotating rods are provided at both ends of the conveying member 2. The rotating rods and the sliders rotate in coordination. A pushing member 3 is provided on the placement seat, and the output end of the pushing member 3 is connected to the slider close to the air knife 1 for adjusting the position of the slider. When the air knife 1 rotates, the pushing member 3 drives the conveying member 2 to rotate synchronously.

[0015] The effect is that when the identification member detects that there are debris on the surface of the battery cell, the push member three drives the slider to move and adjusts the position of the slider. While the slider moves, it drives the conveying member two to rotate to an inclined state, that is, the conveying member two rotates with the air knife one. As the conveying member two rotates, the battery cell is synchronously in a slightly inclined state, so that the air knife one can clean the debris on the battery cell.

[0016] Preferably, the robotic arm is provided with a sensor for detecting the number of battery cells on the robotic arm, the sensor is electrically connected to the controller, the control end of the controller is connected to the air knife 1 for adjusting the blowing size of the air knife 1, and two pushers 3 and two sliders are correspondingly provided. When the sensor detects that there is more than one battery cell on the robotic arm, the controller controls the two pushers 3 to synchronously push the conveying member 2 toward the robotic arm.

[0017] The effect is that when the robot arm is transferring battery cells, when it transfers two or more battery cells that are adsorbed together, the sensor detects that the weight of the battery cells exceeds a preset value and sends a signal to the controller. After receiving the signal, the controller controls the air knife to increase the wind force, and before the robot arm drives the battery cells to move into the blowing range of the air knife, the battery cells that are adsorbed together are blown down, so as to ensure the loading operation of a single battery cell and improve the loading accuracy.

[0018] Preferably, a baffle is provided on the material preparation seat, and the baffle is arranged on one side of the conveying member 1. A push plate is provided on the conveying member 1, and the push plate is arranged at one end of the conveying member 1 away from the lifting member, and the push plate is arranged perpendicular to the baffle.

[0019] The effect is that a baffle and a push plate are arranged on the material preparation seat so as to neatly place the stacked battery cells on the conveyor member 1. At the same time, a push plate is arranged on the conveyor member 1, and the push plate abuts against the side of the battery cells away from the conveyor member 2. When the conveyor member 1 rotates, the push plate is driven to move, so that the battery cells are pushed by the push plate while moving, thereby reducing the tilt of the stacked battery cells and improving the stability of the transfer of the stacked battery cells.

[0020] Preferably, a support member is provided on the material preparation seat, and the support member is provided on the side of the conveying member 1 for supporting the battery cell, and the output end of the conveying member 1 extends to the outside of the support member.

[0021] The effect is that a support member is arranged on the material preparation seat to provide auxiliary support to the battery cell through the support member, and at the same time, the output end of the conveying member one is extended to the outside of the support member, so that after the conveying end of the conveying member one moves between the conveying members two, the support member can support the battery cell, thereby further improving the stability of the battery cell during movement.

[0022] Preferably, a baffle frame is provided on the side of the lifting member in the vertical direction, and two of the baffle frames are provided on both sides of the placement seat. The two baffle frames are provided with different lengths, and the end of the baffle frame close to the top of the lifting member is flush, and the baffle frame with a shorter length is provided close to the conveying member, and when the conveying member moves toward the placement member, the placement member is flush with the bottom of the baffle frame with a longer length.

[0023] The effect is that the baffles are set to different lengths. When conveyor member one conveys the battery cell, the battery cell moves through the shorter baffle frame to conveyor member two until the battery cell moves to abut against the longer baffle frame, so as to push the battery cell to a specified position. As the lifting member works, the battery cell moves between the two baffle frames, further improving the stability of the battery cell when moving upward.

[0024] Preferably, air knife 2 is arranged on the side of the lifting member facing away from air knife 1, the control end of the controller is connected to the switch of air knife 2, and when the identification member detects debris on the battery cell, the controller controls air knife 2 to stop working.

[0025] The effect is that the air knife 1 and the air knife 2 are arranged on both sides of the lifting member, and the two cooperate to make the battery cell bear force more evenly, so as to separate the battery cell from the adjacent battery cell.

[0026] Beneficial effects:

[0027] 1. The present invention arranges a plurality of placement members on the lifting frame to form a plurality of placement platforms for placing battery cells in the vertical direction. The placement platform at the top drives the battery cells to cooperate with the robot arm for loading. The material preparation seat drives the conveying member to move to the placement platform, and transfers the spare battery cells to the placement platform at the bottom for material preparation. After the loading of the battery cells at the top is completed, the lifting member drives the battery cells at the bottom to move to the top to continue loading, and this is repeated to realize the operation of filling without stopping the machine, thereby improving the processing efficiency.

[0028] 2. A collection frame for collecting debris on the surface of the battery cell is set on one side of the lifting member. When loading, when the identification member detects the presence of debris on the battery cell, the controller controls the air knife to rotate to an inclined state towards the battery cell to blow the debris into the collection frame, thereby cleaning the debris and improving the subsequent processing quality of the battery cell.

[0029] 3. When the robot arm absorbs the battery cells through the suction cup, the sensor detects the number of battery cells absorbed. When the number of battery cells on the robot arm exceeds one, the controller receives the signal from the sensor to control air knife 1 and air knife 2 to increase the wind force to separate the two battery cells adsorbed together. At the same time, the pusher 3 pushes the two sliders to move synchronously, thereby driving the placement platform to move toward the robot arm, reducing the distance the battery cells fall back, buffering the battery cells, and reducing the damage to the battery cells when they fall.

[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figures 1 to 10 As shown, the photovoltaic cell stacking material loading device of the present invention includes a frame 1, on which a conveying component 2, a loading component 3 and a preparation component 4 are arranged. The preparation component 4 is used to transfer the spare cell 01 to the loading component 3, and the loading component 3 is used to place the stacked cell 01 and place the cell 01 on the conveying component 2 in sequence. In this embodiment, the conveying component 2 uses a belt conveyor. After the cell 01 enters the conveying component 2, it is transported to the next process for processing through the conveying component 2.

[0044] Reference Figures 2 to 4The loading assembly 3 includes a lifting member 31, a placing member 32 and a mechanical arm 33. The lifting member 31 is a vertically arranged belt conveyor. The placing member 32 is connected to the lifting member 31, that is, the lifting member 31 can drive the placing member 32 to move in the vertical direction. The placing member 32 is used to place the stacked battery cells 01. The mechanical arm 33 is arranged on the frame 1, and the mechanical arm 33 is arranged at the end of the lifting member 31 away from the ground. A suction cup 331 is arranged at the end of the mechanical arm 33 close to the lifting member 31. When loading, the stacked battery cells 01 are placed on the placing member 32, and the lifting member 31 rotates, and the stacked battery cells 01 are driven to move vertically upwards through the placing member 32, that is, move toward the mechanical arm 33. After the battery cell 01 at the top moves to the suction cup 331, the suction cup 331 absorbs the battery cell 01, and then the mechanical arm 33 drives the battery cell 01 to move, and then places it on the conveying assembly 2. During the loading process, as the battery cell 01 is gradually transferred to the conveying assembly 2 , the lifting member 31 drives the placing member 32 to move continuously, so that the suction cup 331 repeatedly sucks the battery cell 01 for loading.

[0045] Reference Figure 2 and Figure 5 The material preparation assembly 4 includes a material preparation seat 41, a conveying member 42 and a pushing member 43. The pushing member 43 can be set as a cylinder. The pushing member 43 is set in the frame 1. A slide bar 431 is set at the output end of the pushing member 43. The slide bar 431 slides horizontally toward the lifting member 31. The material preparation seat 41 is set on the side of the slide bar 431 away from the pushing member 43. The conveying member 42 is set on the material preparation seat 41. The conveying member 42 is set as a belt conveyor. The conveying member 42 is used to place the spare stacked battery cells 01. Figure 3 There are multiple placement pieces 32, and the multiple placement pieces 32 are arranged at intervals around the lifting piece 31. There are two groups of lifting pieces 31 and placement pieces 32. The two groups of lifting pieces 31 are arranged at intervals in the horizontal direction. The gap between the two groups of lifting pieces 31 is set corresponding to the preparation seat 41. After the two placement pieces 32 in the two groups are rotated between the two groups of lifting pieces 31, every two placement pieces 32 on the same horizontal plane form a platform for placing the battery cells 01, so that there are multiple platforms for placing the battery cells 01 between the two groups of lifting pieces 31 at the same time.

[0046] When loading, the pushing member 43 pushes the material preparation seat 41 to move, and the material preparation seat 41 drives the conveying end of the conveying member 42 to move between the two groups of placement members 32. At the same time, the conveying member 42 and the placement member 32 are in the same plane, and then the conveying member 42 conveys the battery cell 01 to the placement member 32, and then places the battery cell 01 on the placement platform near the bottom of the lifting member 31 for standby use, thereby realizing the addition of materials without stopping the machine and improving the loading efficiency.

[0047] Reference Figure 5A baffle 411 is provided on the material preparation seat 41, and the baffle 411 is provided on one side of the conveying member 42. In addition, a push plate 421 is provided on the conveying member 42, and the push plate 421 is provided perpendicular to the baffle 411, and the push plate 421 is provided at one end of the conveying member 42 away from the lifting member 31. When placing the battery cell 01, the adjacent two sides of the battery cell 01 are respectively abutted against the baffle 411 and the push plate 421, so that the battery cells 01 are stacked more neatly. At the same time, when the conveying member 42 rotates, the battery cell 01 can be pushed to the placement member 32 through the push plate 421.

[0048] Reference Figure 5 A support member 412 is also provided on the material preparation seat 41. The support member 412 is also provided as a belt conveyor. Two groups of support members 412 are provided, and the two groups are provided on both sides of the conveying member 42. The end of the support member 412 away from the lifting member 31 is flush with the end of the conveying member 42, and the output end of the conveying member 42 extends to the outside of the support member 412. The upper surface of the support member 412 is flush with the upper surface of the conveying member 42. The support member 412 is provided to support the battery cell 01 and improve the stability of the battery cell 01 during transportation. At the same time, the output end of the conveying member 42 extends to the outside of the support member 412 so as to transfer the battery cell 01 to the placement member 32.

[0049] Reference Figure 6 and Figure 7 The placement member 32 includes a placement seat 321 and a second conveying member 322. The placement seat 321 is connected to the lifting member 31. The second conveying member 322 also uses a belt conveyor. The second conveying member 322 is horizontally arranged on the placement seat 321, and the second conveying member 322 and the first conveying member 42 are arranged in the same direction. When the first conveying member 42 drives the battery cell 01 to move onto the second conveying member 322, the second conveying member 322 rotates synchronously so that the battery cell 01 enters the second conveying member 322, and at the same time reduces the friction force on the battery cell 01 during the transfer process, protects the battery cell 01, and reduces the damage to it.

[0050] Reference Figure 6 and Figure 7, a baffle 5 is arranged on the side of the lifting member 31, and the baffle 5 is arranged in the vertical direction. There are two baffles 5, and the two baffles 5 are arranged on both sides of the placement seat 321. When the lifting member 31 drives the battery cell 01 to move upward, the battery cell 01 is blocked by the side of the lifting member 31 and the baffle 5, so as to reduce the tilting phenomenon of the stacked battery cells 01 during the movement, so as to facilitate the subsequent transfer. In order to facilitate the transportation of the spare battery cell 01 to the designated position, two baffles 5 are arranged with different lengths, and the two baffles 5 are flush with one end of the lifting member 31, and the shorter baffle 5 is arranged close to the conveying member 1 42. When the conveying member 2 322 moves to be flush with the bottom of the longer baffle 5, the conveying member 1 42 drives the battery cell 01 to pass through the shorter baffle 5 and enter the conveying member 2 322 until the battery cell 01 moves to abut against the other baffle 5, and then the lifting member 31 drives the battery cell 01 to move upward into the two baffles 5 to complete the material preparation.

[0051] Reference Figure 7 and Figure 8 The material preparation seat 41 is slidably arranged on the slide bar 431 in the vertical direction, and a pusher 432 is arranged on the slide bar 431. The pusher 432 can be arranged as a cylinder, and the output end of the pusher 432 is connected to the material preparation seat 41. The pusher 432 is used to drive the material preparation seat 41 to move in the vertical direction. After the spare battery sheet 01 is placed on the conveying member 1 42, the pusher 432 drives the material preparation seat 41 to move downward to the material preparation area for subsequent material preparation.

[0052] Reference Figure 3 and Fig. 9 The frame 1 includes a mounting plate 11, which is arranged on one side of the lifting member 31. An air knife 6 is arranged on the mounting plate 11, and the air knife 6 is arranged near the top of the lifting member 31 and is arranged toward the lifting member 31. When loading, the top battery sheet 01 is blown up by the air knife 6 to separate it from the adjacent battery sheets 01, so that the suction cup 331 can suck the top battery sheet 01 for loading.

[0053] Reference Fig. 9, because the solar cell 01 has a tendency to become thinner and lighter, and the cell 01 at some workstations has obvious bending deformation and protruding grid lines, the cell 01 is often damaged when being transported by the above two methods. Common damages include hidden damage, missing corners, collision, sticking, and jamming. As the thickness of the cell 01 becomes thinner, the probability of damage increases sharply. In view of this phenomenon, the present embodiment is provided with a collection frame 7 on the side of the lifting member 31 away from the air knife 6. The collection frame 7 is arranged on the mounting plate 11. The side of the collection frame 7 is provided with an opening 71, and the opening 71 is arranged horizontally toward the air knife 6. When there are debris on the surface of the cell 01, the air knife 6 blows the debris through the opening 71 into the collection frame 7 for collection, so as to reduce the debris from entering the next process with the cell 01 and affecting the processing quality. A pull frame 72 connected to the collection frame 7 is provided below the collection frame 7, and the pull frame 72 is slidably arranged on the mounting plate 11. The debris in the collecting frame 7 can enter the pull frame 72, and then the pull frame 72 can be pulled out from the mounting plate 11 to carry out centralized processing of the debris.

[0054] Reference Fig. 9 and Fig.10 , the collection frame 7 and the air knife 6 are arranged at intervals in the vertical direction, and the collection frame 7 is arranged on the side of the air knife 6 close to the ground. The air knife 6 is rotatably arranged on the mounting plate 11, and a rotating member 12 is arranged on the mounting plate 11. The rotating member 12 can be set as a motor, and the output end of the motor is connected to the air knife 6. The output end of the rotating member 12 is connected to the air knife 6 for adjusting the blowing angle of the air knife 6. An identification member 9 is arranged on the robot arm 33, and the identification member 9 is used to identify the debris on the surface of the battery cell 01. In this embodiment, the identification member 9 is set as a visual sensor. A controller is arranged on the frame 1, and the signal output end of the identification member 9 is electrically connected to the signal receiving end of the controller. The control end of the controller is connected to the switch of the rotating member 12, and the controller is used to control the switch of the rotating member 12. During the loading process, when the identification part 9 detects that there are debris on the surface of the battery cell 01, it sends a signal to the controller. After receiving the signal, the controller controls the rotating part 12 to start, and the rotating part 12 drives the air knife 6 to rotate, so that the air outlet of the air knife 6 is tilted toward the upper surface of the battery cell 01, so that the air knife 6 can blow the debris on the battery cell 01 into the collection frame 7, thereby improving the cleaning effect of the debris.

[0055] Reference Figure 8Two sliders 8 are slidably arranged on the placement seat 321 in the vertical direction. The two sliders 8 are respectively arranged at the two ends of the conveying member 2 322. A pusher 3 81 is arranged on the placement seat 321. The pusher 3 81 can be arranged as a cylinder, and the output end of the cylinder is connected to the slider 8. Both ends of the conveying member 2 322 are provided with a rotating rod 82, and the rotating rod 82 and the slider 8 rotate in coordination. When the controller drives the air knife 1 6 to rotate, the pusher 3 81 near one end of the air knife 1 6 pushes the slider 8 to move, so that the conveying member 1 42 tilts, and then drives the battery sheet 01 to tilt with the air knife 1 6, further improving the cleaning effect of the air knife 1 6 on the debris.

[0056] Reference Fig.10 A sensor 91 is provided on the mechanical arm 33. The sensor 91 is used to detect the weight of the battery cell 01 sucked by the suction cup 331. In this embodiment, the sensor 91 is set as a gravity sensor. The number of battery cells 01 sucked by the suction cup 331 is judged by detecting whether the weight borne by the suction cup 331 exceeds a specified value. The signal output end of the sensor 91 is electrically connected to the signal receiving end of the controller. The control end of the controller is connected to the air knife 6 to control the blowing size of the air knife 6. When loading, when the sensor 91 detects that the suction cup 331 sucks more than one battery cell 01, it sends a signal to the controller. After receiving the signal, the controller controls the air knife to increase the wind force. When the suction cup 331 fails to drive the battery cell 01 to move outside the coverage range of the air knife, the excess battery cell 01 is blown off. In addition, when the controller controls to increase the wind force of the air knife, the two pushers 3 81 simultaneously push the conveyor 2 322 upward, and the conveyor 2 322 moves to reduce the distance between it and the suction cup 331, thereby reducing the height of the battery cell 01 falling and reducing the damage to the battery cell 01.

[0057] Reference Fig. 9 In order to improve the blowing effect on the battery cell 01, the air knife 2 61 is arranged at the collection frame 7, that is, the air knife 2 61 and the air knife 1 6 are respectively arranged on both sides of the lifting member 31, and the air knife 2 61 and the air knife 1 6 have the same structure. The air knife 2 61 cooperates with the air knife 1 6 to blow air toward the battery cell 01, so that the battery cell 01 is evenly stressed, and the separation effect of the battery cell 01 and the adjacent battery cell 01 is improved. In this embodiment, the control end of the controller is connected to the switch of the air knife 2 61. When the identification member 9 detects that there are debris on the surface of the battery cell 01, the air knife 2 61 stops working, and only the air knife 1 6 works to blow the debris into the collection frame 7.

[0058] Reference Figure 1 In other embodiments, two groups of loading components 3 and preparation components 4 are provided, one of which is used as a spare. The two groups of loading components 3 and preparation components 4 are arranged along the conveying direction of the conveying component 2. When one of the groups has a problem or needs to be corrected and adjusted, the spare group can be used for loading, thereby further improving the loading efficiency.
