Description

Technical Field

[0001] The invention relates to a material unloading process and system of a cell passivation machine, belonging to the technical field of solar cell production. Background Art

[0002] In the photovoltaic industry, the processing of the cut surface of the cell is a crucial link. The cut surface of the cell is repaired by coating with a passivation machine, thereby achieving the purpose of improving the power generation rate of the cell.

[0003] In the cell passivation process, including loading, that is, the cell and carrier enter the passivation machine, and unloading, that is, the cell and carrier are output from the passivation machine, efficient, accurate and stable unloading technology and equipment are the key to ensure the smoothness of the entire production process and stable product quality. This application aims to develop an efficient, intelligent, low-damage cell passivation machine unloading process and equipment, which can achieve precise positioning, rapid grasping and placement of the cell, while ensuring that no physical damage is caused to the cell during the entire unloading process, so as to meet the photovoltaic industry's demand for efficient and high-quality production, and promote technological progress and industrial upgrading in the photovoltaic industry. Summary of the invention

[0004] In view of the above deficiencies in the prior art, the present invention provides a material unloading process and system for a battery cell passivation machine that can achieve efficient, safe and damage-free battery cell unloading by optimizing the unloading process and improving the accuracy and intelligence level of the equipment.

[0005] The blanking process of the cell passivation machine of the present invention comprises the following steps:

[0006] S1, the unloading system receives the passivation carrier loaded with the pallet and the battery cells output by the passivation machine;

[0007] S2, transporting the pallet in the passivation carrier together with the whole stack of battery cells to the temporary storage mechanism;

[0008] S3, picking up the topmost battery cells from the temporary storage mechanism in sequence and outputting them until all the battery cells in the temporary storage mechanism have been output;

[0009] S4, moving the pallet in the temporary storage mechanism into the passivation carrier;

[0010] S5. Output of the passivation carrier with pallet.

[0011] In step S2, the front opening of the passivation carrier is turned 90 degrees to make the front opening of the passivation carrier stand upright, and then the passivation carrier is transported to the transfer station to wait for the pallet and the whole stack of battery cells to be moved out. The front opening of the passivation carrier stands upright to facilitate the insertion and removal of the whole stack of battery cells. During the transportation process, the battery cells are in a horizontal state, and the handling manipulator applies a small force to stabilize the whole stack of battery cells to prevent them from being clamped (a larger clamping force is required when the whole stack of battery cells is in a vertical state).

[0012] In step S2, after the passivation carrier is transported to the transfer station, it is horizontally rotated so that the front opening of the passivation carrier faces the execution part of the transport mechanism, and then the pallet and the whole stack of battery cells are transported.

[0013] In step S2, a top cover is provided on the top surface of the passivation carrier. After the top cover is opened, it prevents the movement interference of the handling robot, and the pallet together with the whole stack of battery cells is moved out from the front opening of the passivation carrier.

[0014] In step S4, debris on the surface of the pallet is cleaned and then transported to the passivation carrier.

[0015] In step S5, the top cover of the passivation carrier is closed, and the passivation carrier is horizontally rotated to an initial angle before being discharged from the unloading system.

[0016] The unloading system of the battery cell passivation machine of the present invention comprises:

[0017] A tray for supporting the battery cells;

[0018] Passivation carriers for loading pallets and stacks of cells;

[0019] A transport mechanism for transporting pallets and stacks of cells;

[0020] A temporary storage mechanism for temporarily storing and transferring a whole stack of battery cells;

[0021] A cell picking mechanism for picking up and transporting a single cell;

[0022] The transport mechanism can transport the pallet and the whole stack of battery cells from the passivation carrier to the temporary storage mechanism, and the battery cell picking mechanism can pick up the top battery cell from the temporary storage mechanism and output it.

[0023] The pallet is used to support the battery cells and serves as a platform for stacking the battery cells.

[0024] The passivation carrier comprises a box body with openings on the front and top, and a closable upper cover on the top of the box body, which is fixed by claws with self-locking function on both sides of the top of the box body. When the upper cover is closed, it is used to limit the support plate and the whole stack of battery cells in the box body to prevent the battery cells from falling when the box body is lying flat (when passivation is performed in the passivation machine).

[0025] The present invention also includes a cover opening and closing mechanism, which includes a claw that can push the claws to both sides, and also includes a cover lifting module that can grab the cover and drive it to rise and fall. After the claws push the claws of the passivation carrier to both sides, the cover lifting module can drive the cover to detach from the top of the box body; after the support plate and the whole stack of battery cells are moved out of the box body, the cover lifting module drives the cover to fall, the claws are reset to the middle and the claws lock the cover.

[0026] The temporary storage mechanism includes a plurality of temporary storage units, which are divided into two groups. The two groups of temporary storage units run alternately between the waiting station and the unloading station. The temporary storage mechanism at the waiting station receives the pallet and the whole stack of battery cells; the temporary storage mechanism at the unloading station outputs the top battery cell through a battery cell picking mechanism with a suction cup.

[0027] The present invention also includes a flipping mechanism that can flip the passivation carrier 90 degrees so that the front opening of the passivation carrier stands upright; transverse coaxial flipping pins are provided on both sides of the box body of the passivation carrier, and the flipping mechanism includes a pair of lifting claws for grabbing the flipping pins and lifting them up. After the lifting claws rise, the passivation carrier rotates around the flipping pins under the action of its own weight to achieve a flipping action.

[0028] The present invention also includes a full carrier conveyor line for receiving fully loaded passivated carriers and an empty carrier conveyor line for returning empty passivated carriers. The full carrier conveyor line is located below the flipping mechanism, and the empty carrier conveyor line is located below the full carrier conveyor line. A rotating lifting mechanism is provided between the full carrier conveyor line and the empty carrier conveyor line for driving the passivated carriers to rotate and lift.

[0029] The present invention also includes a pallet debris cleaning mechanism, which includes a pallet and a debris collection box with an upward opening. The pallet is provided with a pallet fixing device, and the pallet can be flipped to the side where the debris collection box is located to pour the battery cell debris on the pallet into the collection box.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Efficient unloading: By optimizing the unloading process, the present invention realizes fast and efficient unloading of battery cells, and realizes accurate positioning, rapid grasping and placement of battery cells, thereby improving production efficiency.

[0032] 2. Safe and damage-free: During the handling process, the handling robot has a small clamping force on the entire stack of battery cells, which effectively prevents physical damage to the battery cells. At the same time, the debris cleaning mechanism cleans the pallet to prevent the battery cells from being contaminated or damaged during the unloading process.

[0033] 3. High level of intelligence: The present invention can realize precise control and monitoring of the material feeding process by introducing automated equipment and intelligent control systems, which not only improves production efficiency but also ensures the stability of product quality.

[0034] The present invention achieves efficient, safe and damage-free cutting of battery cells by optimizing the cutting process and improving the accuracy and intelligence level of equipment, providing strong technical support for the development of the photovoltaic industry.

[0084] S5. The top cover of the passivation carrier is closed, the passivation carrier is rotated horizontally to the initial angle, and the passivation carrier with the pallet is output from the unloading system.

[0085] The unloading system of the battery cell passivation machine of this embodiment includes:

[0086] A support plate 15 for supporting the battery cell 14;

[0096] An empty carrier conveyor line 10 for outputting the passivated carrier 1;

[0097] A pallet debris cleaning mechanism 11 is used for cleaning the pallet 15 .

[0098] The support plate 15 is used to support the battery cells 14 and serves as a platform for stacking the battery cells 14. Two slots 15.1 are provided at the bottom of the support plate 15 to facilitate the insertion of the lower half of the transporting clamps 6.1 of the transport mechanism 6.

[0099] The passivation carrier 1 of this embodiment includes a box body 1.1 with an opening on the front and top surfaces, and an openable upper cover 1.2 is provided on the top of the box body 1.1. The upper cover 1.2 is fixed by claws 1.3 with self-locking functions on both sides of the top of the box body 1.1. When the upper cover is closed, it is used to limit the support plate and the whole stack of battery cells in the box body to prevent the battery cells from tipping over when the passivation carrier is lying flat (when passivation is carried out in the passivation machine). Opening pin holes 1.4 that cooperate with the opening and closing cover mechanism 5 are provided on the end surfaces on both sides of the upper cover 1.1. Transversely coaxial flip pins 1.5 that cooperate with the flip mechanism 3 are provided on both sides of the box body 1.1, and positioning pin holes 1.6 are provided on the bottom surface of the box body 1.1.

[0100] The flipping mechanism 3 is located above the fully loaded carrier conveyor line 2. The flipping mechanism 3 of this embodiment includes a pair of lifting jaws 3.1. The lifting jaws 3.1 are provided with a semi-cylindrical groove that cooperates with the above-mentioned flip pin 1.5. Under the action of the lifting jaw opening and closing cylinder 3.2, the lifting jaws 3.1 can move inward and outward relatively. A pressure plate 3.4 is provided above the pair of lifting jaws 3.1. Under the action of the pressure plate driving electric cylinder 3.5, the pressure plate 3.4 can be pressed down. The entire flipping mechanism 3 can be raised and lowered as a whole under the action of the lifting drive motor 3.3. After the lifting jaws 3.1 rise, the passivation carrier 1 rotates around the flip pin 1.5 under the action of its own weight to achieve the flipping action, and then cooperates with the pressure plate 3.4 to press down to the top surface of the passivation carrier 1, which can flip the passivation carrier 1 90° to make the passivation carrier 1 upright.

[0101] The rotary lifting mechanism 4 of this embodiment includes a carrier lifting conveyor line 4.1, which is composed of a pair of parallel conveyor belts, and the conveyor belts are driven by a lifting conveyor line drive motor 4.2. A rotating platform 4.3 is arranged between the pair of parallel conveyor belts, and the rotating platform 4.3 can rotate under the action of a rotating platform drive motor 4.4. The rotating platform 4.3 can also be lifted relative to the carrier lifting conveyor line 4.1 under the action of a rotating platform lifting cylinder 4.7. A positioning column 4.5 is arranged on the rotating platform 4.3 to cooperate with the above-mentioned positioning pin hole 1.6. The rotary lifting mechanism 4 can be lifted and lowered as a whole under the action of a conveyor line lifting module 4.6.

[0102] The cover opening and closing mechanism 5 of this embodiment includes a claw 5.1 that can push the clamping claw 1.3 to both sides, and the claws 5.1 on both sides are driven by a horizontal claw cylinder 1.2 respectively; and also includes a cover lifting module that can grab the upper cover 1.2 and drive it to rise and fall. The upper cover lifting module includes a pair of upper cover clamps 5.3 driven by the upper cover clamp opening and closing cylinder 5.5, and an upper cover lifting cylinder 5.6 that can drive the upper cover clamps 5.3 to rise and fall. The inner side of the upper cover clamps 5.3 is provided with a cover opening pin 5.4 that can be inserted into the cover opening pin holes 1.4 on the end surfaces of the upper cover 1.2. The cover opening and closing mechanism 5 can be lifted and lowered as a whole under the action of the overall lifting cylinder 5.7. After the pusher claw 5.1 pushes the claw 1.3 of the passivation carrier 1 to both sides, the upper cover lifting module can drive the upper cover 1.2 to detach from the top of the box body 1.1, thereby realizing the opening action; the upper cover lifting module drives the upper cover 1.2 to fall, the upper cover clamping claw 5.3 is released, and the opening pin 5.4 is disengaged from the opening pin hole 1.4 on the side of the upper cover 1.2, the pusher claw 5.1 is reset to the middle and retracted, and the claw 1.3 locks the upper cover 1.2, thereby realizing the closing action.

[0103] The transport mechanism 6 of this embodiment comprises a transport clamp 6.1, which is driven by a transport clamp opening and closing cylinder 6.2. The transport clamp 6.1 can be lifted and lowered and moved laterally under the drive of a transport clamp lifting module 6.3 and a transport clamp transverse module 6.4.

[0104] The temporary storage mechanism 7 of this embodiment includes a plurality of temporary storage units 7.4, each of which is surrounded by a plurality of barrier arms 7.5 to form a temporary storage area. Each temporary storage unit 7.4 of this embodiment includes two temporary storage areas. The plurality of temporary storage units 7.4 are divided into two groups. The two groups of temporary storage units 7.4 can alternately reciprocate between the waiting station 12 and the unloading station 13 driven by the transmission belt 7.1. The temporary storage mechanism 7 at the waiting station 12 receives the pallet 15 and the whole stack of battery cells 14; the temporary storage mechanism 7 at the unloading station 13 outputs the single battery cell on the top layer. A unloading air blowing air knife assembly 7.2 is provided on the side of the temporary storage unit 7.4, which can blow air to the battery cell on the top of the temporary storage unit 7.4. The temporary storage unit 7.4 can be raised and lowered by the lifting electric cylinder 7.3. There are stacks of battery cells in the temporary storage unit 7.4. When unloading, only the top battery cell is taken out through the Bernoulli suction cup 8.1. Due to the adsorption between the battery cells, it is easy to lift up the battery cells below. The air knife blows air between the first layer of battery cells and the battery cells below to blow the first layer of battery cells and the battery cells below apart so that they are not stuck together. During the process of taking out the battery cells, as the number of battery cells continues to decrease, the lifting cylinder 7.3 drives the temporary storage unit 7.4 to step up, so that the air knife always acts on the top battery cell area.

[0105] The cell picking mechanism 8 of this embodiment includes a plurality of Bernoulli suction cups 8.1 corresponding to the temporary storage unit 7.4, and the plurality of Bernoulli suction cups 8.1 constitute a suction cup group, which can be lifted and lowered and moved laterally under the drive of the suction cup lifting module 8.2 and the suction cup lateral movement module 8.3. The cell in the temporary storage mechanism 7 is transferred to the cell conveying line 9 through the suction cups.

[0106] This embodiment also includes an empty carrier conveyor line 10 for returning empty passivated carriers. The empty carrier conveyor line 10 is located below the fully loaded carrier conveyor line 2. The rotating lifting mechanism 4 is located between the fully loaded carrier conveyor line 2 and the empty carrier conveyor line 10. The empty passivated carrier is transported to the empty carrier conveyor line 10 via the rotating lifting mechanism 4.

[0107] This embodiment also includes a pallet debris cleaning mechanism 11, which includes a tray 11.1 and a debris collection box 11.7. The tray 11.1 is provided with a pallet fixing device, and the tray 11.1 can be turned over to the side where the debris collection box 11.7 is located. The pallet fixing device is located at a fixed clamping plate 11.2 at one end of the tray 11.1 and a movable clamping plate 11.3 at the other end. The fixed clamping plate 11.2 and the movable clamping plate 11.3 are relatively parallelly arranged, and the movable clamping plate 11.3 can move toward the direction of the fixed clamping plate 11.2 under the action of the clamping plate cylinder 11.4. It also includes a pallet tilting cylinder 11.5 as a pallet driving device, the cylinder end of the pallet tilting cylinder 11.5 is rotatably connected to the frame body, the telescopic rod end of the pallet tilting cylinder 11.5 is rotatably connected to one end of the swing arm 11.6, and the swing arm 11.6 drives the pallet 11.1 to flip.

[0108] After being output from the passivation machine, the passivation carrier 1 is put on the full-load carrier conveyor line 2. The flip mechanism 3 above the full-load carrier conveyor line 2 flips the passivation carrier 1 from a lying state to an upright state. The full-load carrier conveyor line 2 conveys the passivation carrier 1 to the carrier lifting conveyor line 4.1 of the rotating lifting mechanism 4. The rotating platform 4.3 rises to lift the passivation carrier 1, and then rotates horizontally 90° so that the front opening of the passivation carrier 1 faces the transport clamp 6.1 of the transport mechanism 6. The cover opening and closing mechanism 5 opens the upper cover 1.2 of the passivation carrier 1, and the transporting clamp 6.1 transports the pallet 15 and the whole stack of battery cells 14 from the passivation carrier 1 to the temporary storage unit 7.4 of the temporary storage mechanism 7 located at the waiting station 12. The temporary storage unit 7.4 reciprocates between the waiting station 12 and the unloading station 13. The battery cell picking mechanism 8 picks up the top single battery cell from the temporary storage unit 7.4 located at the unloading station 13 and outputs it to the battery cell conveying line 9. The pallet 15 is transported from the temporary storage unit 7.4 to the tray 11.1 of the pallet debris cleaning mechanism 11 by the transporting clamp 6.1. The tray 11.1 flips over to dump the battery cell debris on the pallet 15 into the debris collection box 11.7, and then the transporting clamp 6.1 transports the pallet 15 to the passivation carrier 1. The cover opening and closing mechanism 5 closes the upper cover 1.2 of the passivation carrier 1. The rotating platform 4.3 rotates to make the passivation carrier 1 rotate horizontally 90°, the rotating platform 4.3 descends, the passivation carrier 1 falls onto the carrier lifting conveyor line 4.1, the carrier lifting conveyor line 4.1 descends and docks with the empty carrier conveyor line 10, and the passivation carrier 1 is output through the carrier conveyor line 10.
