Description

Technical Field

[0001] This application relates to the field of module pressurization technology, and in particular to a pressurization device for automatically installing pressure strips. Background Technology

[0002] In the battery pack manufacturing process, individual cells are bonded together to form modules, and multiple modules are then placed into a box to form a battery pack. After multiple modules are placed into the box, a pressure strip needs to be installed between each pair of adjacent modules and pressure is applied to ensure the stability of the relative positions between the modules.

[0003] Currently, most battery pack pressure strip installation processes on the market are performed manually. The operator first installs the pressure strip onto the shoulder of the battery pack, then manually secures the bolts at both ends using a tightening gun. After completing all the operations, the battery pack is then transferred to a subsequent work station for pressurization.

[0004] In response to the above situation, the inventors found that with the advancement of unmanned operation in the market, this method of pressurizing the installation of pressure strips consumes a lot of manpower and involves multiple workstations with a slow cycle time. Therefore, there is an urgent need to develop an automatic pressurizing device that can achieve automated installation and accelerate the production cycle time. Utility Model Content

[0005] To address the issues of high manpower consumption and slow production cycle, this application provides an automatic pressure device for installing pressure strips.

[0006] The pressurizing equipment and process for automatically installing pressure strips provided in this application adopt the following technical solution: An automatic pressure-pressurizing device and process for installing pressure strips includes an installation truss, a material storage mechanism, a transfer mechanism, a cooperating mechanism, and a material-retrieving mechanism. An AGV (Automated Guided Vehicle) carries a battery pack and moves it into the installation truss. The material storage mechanism is located on one side of the installation truss and is used to temporarily store pressure strips. The transfer mechanism includes a transfer platform with a feeding position and a retrieval position. The cooperating mechanism is used to move the pressure strips temporarily stored in the material storage mechanism to the feeding position, and then the transfer mechanism automatically moves the pressure strips to the retrieval position. The retrieval mechanism is slidably mounted on the installation truss and includes a pressurizing device and a tightening device. The retrieval mechanism uses negative pressure to suck up the pressure strips located at the retrieval position and installs them onto the shoulder of the battery pack. The pressurizing device is used to pressurize the pressure strips and the module, and the tightening device is used to automatically complete the connection between the pressure strips and the battery pack.

[0007] By adopting the above technical solution, the material storage mechanism, the cooperating mechanism and the transfer mechanism work together to achieve fully automatic feeding of the pressing strip. Then, the installation and pressurization of the pressing strip are integrated into one unit through the cooperation of the material picking mechanism and the transfer mechanism, which reduces the number of workstations, reduces the number of links in the battery pack production process, and greatly improves the production cycle.

[0008] Preferably, the transfer mechanism includes a conveying device, which includes a conveying plate, a conveying block, a first driving member and a second driving member. The first driving member and the second driving member are located below the transfer platform. The first driving member is used to drive the conveying plate to rise, and the second driving member is used to drive the conveying plate to move. A plurality of the conveying blocks are evenly arranged on the conveying plate, and the conveying blocks are provided with conveying grooves for placing pressure strips.

[0009] Preferably, the output end of the first driving member is connected to a lifting plate, the lifting plate is provided with a lifting wedge, the conveying plate is rotatably connected to a roller on the side facing the lifting plate, the roller abuts against the lifting wedge, the output end of the second driving member is connected to a moving plate, the first driving member is fixedly connected to the moving plate, the conveying plate is connected to a guide pin, the moving plate is provided with a guide hole through which the guide pin passes, and the conveying plate is movably connected to the moving plate along the Z-axis direction.

[0010] Preferably, the transfer mechanism further includes a positioning device, which includes a positioning block and a positioning pin. At least two positioning blocks are provided along the X-axis direction, and a positioning clamp is provided on each of the at least two positioning blocks. The positioning clamp is used to place and transfer the pressure strip. The positioning pin is connected to the side of the positioning block that is relatively far away from it, and the positioning pin is inserted into the connecting screw hole corresponding to the end of the pressure strip.

[0011] Preferably, the transfer mechanism further includes a fixed platform, a shuttle drive device, a first shuttle plate, and a second shuttle plate. The shuttle drive device is located inside the fixed platform. The first shuttle plate and the second shuttle plate are each provided with a positioning device. The first shuttle plate and the second shuttle plate are used to place pressure strips. The shuttle drive device is used to drive the first shuttle plate and the second shuttle plate to exchange positions along the Y-axis and Z-axis directions.

[0012] Preferably, the material picking mechanism includes a material picking frame, a negative pressure suction plate, and a buffer. The material picking frame is movably connected along the X and Y axes of the mounting truss. The negative pressure suction plate is disposed on the material picking frame and is used to pick up the pressure strip. The buffer is disposed between the material picking frame and the negative pressure suction plate. The material picking frame drives the negative pressure suction plate to move the pressure strip to the module shoulder position to be installed in the battery pack.

[0013] Preferably, a sliding frame is provided on the mounting truss along the Y-axis direction, and the pressurizing device includes a fixed frame, a pressurizing drive, and a pressurizing frame. The fixed frame is slidably connected to the sliding frame along the X-axis direction, the pressurizing drive is located inside the fixed frame, the pressurizing frame is located at the output end of the pressurizing drive, and the pressurizing frame is connected to the material picking frame.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the coordinated setup of the incoming material storage mechanism and the cooperating mechanism, the AGV trolley transfers the pressing strip from the pressing strip hopper to the incoming material storage mechanism. The cooperating mechanism, driven by the preset PLC program, is responsible for grabbing the pressing strip from the incoming material storage platform to the transfer platform. This, combined with the subsequent pressing strip installation and pressurization operations, reduces the waiting time for the material picking mechanism to replenish the pressing strip and ensures the production cycle of pressing strip feeding and installation. 2. The material handling mechanism integrates material handling, pressurization, installation and connection functions. The material handling mechanism moves and positions itself along the X and Y axes of the installation truss. The negative pressure suction plate is used to pick up the pressure strip. As the material handling frame moves, the pressure strip is moved to the corresponding position inside the battery pack. Then, the pressure device pressurizes the pressure strip to make it bonded to the shoulder of the module. Simultaneously, the tightening device achieves the connection between the pressure strip and the shoulder of the module, ensuring the stability of the module position, reducing the defect rate, reducing labor consumption, reducing workstation configuration, reducing battery pack circulation links, and significantly speeding up the production cycle. 3. Through the setting of the transfer mechanism, the structural design of the transfer table, the first placement plate and the second placement plate, the rhythm of the pressing strip feeding of the cooperating mechanism, the stepping conveying of the conveying device and the reciprocating suction of the picking mechanism are cleverly coordinated, which improves production efficiency while effectively ensuring accuracy.

[0025] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0026] Embodiment 1 of this application discloses a pressurizing device for automatically installing pressure strips, referring to... Figure 1 and 2An automatic pressure-pressurizing device for installing pressure strips includes an installation truss 1, a material receiving temporary storage mechanism 2, a transfer mechanism 3, a cooperating mechanism 4, and a material picking mechanism 5. At least two material receiving temporary storage mechanisms 2 are located on one side of the installation truss 1 to temporarily store pressure strips of different blueprint sizes and specifications. The transfer mechanism 3 is located within the installation truss 1, and the cooperating mechanism 4 transfers the pressure strips temporarily stored in the material receiving temporary storage mechanism 2 to the transfer mechanism 3. The material picking mechanism 5 is located on the installation truss 1. The material picking mechanism 5 picks up the pressure strips from the transfer platform 31 and installs them onto the shoulder of the battery pack, then applies pressure to ensure the pressure strips are in place and the battery cell position is stable. The entire device is fully automated, significantly saving manpower. Furthermore, by placing the installation and pressurization of the pressure strips at the same workstation, it reduces turnover and increases production cycle time.

[0027] Reference Figure 2 The incoming material storage mechanism 2 includes multiple storage platforms. In this embodiment, there are two storage platforms, both located on one side of the mounting truss 1. Each storage platform contains several positioning fixtures according to the different specifications of the pressing strips. These fixtures are used to maintain the positional stability of the pressing strips during AGV transport, facilitating subsequent gripping and positioning, and ensuring accuracy. The storage platforms can be used to place pressing strips of the same specifications, or pressing strips of different specifications and sizes according to feeding requirements. Due to the limitations of the production site and the overall structural layout of the equipment, large quantities of pressing strip hoppers are located far from the pressurizing equipment station, requiring AGV transport. The incoming material storage mechanism is set up to temporarily place the pressing strips, ensuring sufficient supply, reducing waiting time, and thus ensuring the feeding cycle of the pressing strips.

[0028] Reference Figure 2 and 4 In this embodiment, a pressure strip made of a composite material with a metal layer is selected. Both ends of the metal layer are provided with connecting screw holes to facilitate the connection between the pressure strip and the module shoulder inside the battery pack. The transfer mechanism 3 is located below the mounting truss 1 and on the side close to the incoming material storage mechanism 2. The transfer mechanism 3 includes a transfer platform 31, a first placement layer 311 and a second placement layer 312. The first placement layer 311 and the second placement layer 312 are connected to the transfer platform 31. The first placement layer 311 and the second placement layer 312 are arranged parallel to each other along the Z-axis direction, and the second placement layer 312 is located below the first placement layer 311. The length of the second placement layer 312 along the Y-axis direction is greater than that of the first placement layer 311, that is, each end protrudes with a pressure strip placement position. The transfer station 31 is provided with a feeding position 314 and a picking position 315. The cooperating mechanism 4 places the pressing strip on the feeding position 314, the transfer mechanism 3 moves the pressing strip from the feeding position 314 to the picking position 315, and then the picking mechanism 5 picks up the pressing strip from the picking position 315.

[0029] Reference Figure 2 , 4In addition to 5, the transfer mechanism 3 also includes a positioning device 32, which includes positioning blocks 321, positioning clamps 322, and positioning pins 323. At least two positioning blocks 321 are provided along the X-axis direction. The number of positioning blocks 321 is determined according to the specifications and dimensions of the pressure strip to be transferred, sufficient to stably support the pressure strip. Positioning grooves are provided on the positioning blocks 321, and a positioning clamp 322 is provided on each of the at least two positioning blocks 321 along the X-axis direction. The positioning clamp 322 is made of a plate with a concave cross-section and is used to place and transfer the pressure strip.

[0030] Reference Figure 2 and 3 The collaborative mechanism 4 includes a robot body 41 and a collaborative gripper 42. The robot body 41 is located between the incoming material storage mechanism 2 and the transfer mechanism 3, and the collaborative gripper 42 is connected to the end of the robot body 41. The collaborative gripper 42 includes a connecting frame 421, a sponge suction cup 423, and a detection camera 422. The connecting frame 421 is fixedly connected to the end of the robot body 41, and the detection camera 422 is fixedly connected to the connecting frame 421 and located on one side of the sponge suction cup 423. When the sponge suction cup 423 grips the pressure strip on the storage table, the detection camera 422 takes a picture of the pressure strip and records it. A gripping cylinder 426 is fixedly connected to the connecting frame 421, and the sponge suction cup 423 is connected to the end of the piston rod of the gripping cylinder 426 through a floating joint 427. A first slide rod 424 is fixedly connected to the sponge suction cup 423, and a second slide rod 425 is fixedly connected to the connecting frame 421. A guide rail is installed between the first slide rod 424 and the second slide rod 425.

[0031] When the collaborative gripper 42 picks up the pressure strip on the storage table using the sponge suction cup 423, to prevent the detection camera 422 from colliding with the positioning fixture, the gripping cylinder 426 drives the sponge suction cup 423 to press down and grip independently during the gripping process. This protects the equipment, reduces damage, and extends its service life. The collaborative gripper 42 picks up the pressure strip and places it on the feeding position 314 on the first placement layer 311. The pressure strip is then repositioned through the cooperation of the positioning clamp 322 and the positioning pin 323.

[0032] Reference Figure 4 , 5In addition to component 6, the transfer mechanism 3 also includes a conveying device 33, which includes a conveying plate 337, a conveying block 338, a first driving component 331, and a second driving component 334. Both the first driving component 331 and the second driving component 334 are cylinders. The second driving component 334 is fixedly connected to the transfer platform 31, and a moving plate 335 is connected to the output end of the second driving component 334. A surrounding frame 336 is fixedly connected to the moving plate 335. Relief grooves 313 are provided on both opposite sides of the transfer platform 31 for the surrounding frame 336 to be installed. The length of the relief grooves 313 is the distance that the moving plate 335 moves. The first driving component 331 is fixedly connected to the moving plate 335, and a lifting plate 332 is fixedly connected to the output end of the first driving component 331. A lifting wedge 333 is fixedly connected to the lifting plate 332. A roller (not shown in the figure) is rotatably connected to the side of the conveying plate 337 facing the lifting plate 332, and the roller abuts against the lifting wedge 333. A guide pin 3371 is connected to the conveyor plate 337, and a guide hole for the guide pin 3371 to pass through is provided on the movable plate 335. The guide hole is an oblong hole. The conveyor plate 337 is movably connected to the movable plate 335 along the Z-axis direction.

[0033] Reference Figure 5 and 6 Several conveying blocks 338 are uniformly fixedly connected to the conveying plate 337 along the Y-axis. The conveying blocks 338 are provided with conveying grooves for placing the pressure strips. In order to facilitate the conveying of the pressure strips, wedge-shaped surfaces are provided on the opposite sides of the groove walls of the conveying groove and the positioning groove along the Y-axis. The wedge-shaped surfaces facilitate the conveying blocks 338 to lift the positioning clamp 322 and drive the positioning clamp 322 to move out of the positioning groove.

[0034] After the pressure bar is positioned and controlled by the positioning device 32, the first drive unit 331 operates, driving the lifting plate 332 and the lifting wedge 333 to move, causing the rollers to roll relative to the lifting wedge 333. This causes the conveying plate 337 to rise relative to the moving plate 335, thereby driving the conveying block 338 and the pressure bar located on the conveying plate 337 to rise synchronously, facilitating the pressure bar to disengage from the positioning block 321. Then, the second drive unit 334 operates, driving the moving plate 335 to move. The moving plate 335 drives the guide pin 3371 and the conveying plate 337 to move synchronously. According to the PLC preset program, the movement distance each time is the width of one pressure bar placement station. The conveying device 33 operates cyclically, feeding the material handling mechanism 5.

[0035] Reference Figure 1 , 27. A sliding frame 10 is provided on the mounting truss 1 along the Y-axis. The material handling mechanism 5 includes a pressurizing device, which includes a fixed frame 51, a pressurizing drive 52, and a pressurizing frame 53. The fixed frame 51 is slidably connected to the sliding frame 10 along the X-axis. The pressurizing drive 52 is fixedly connected to the outside of the fixed frame 51 and can be a motor. The pressurizing frame 53 includes a lifting moving part 531 and a pressurizing part 532. The lifting moving part 531 passes through the fixed frame 51. The motor is connected to the lifting moving part 531 through a gear and rack for drive. The pressurizing part 532 is fixedly connected to the lifting moving part 531.

[0036] Reference Figure 7 The material handling mechanism 5 also includes a material handling frame 54 and a negative pressure suction plate 55. The material handling frame 54 is connected below the pressurizing unit 532. The negative pressure suction plate 55 is connected to the side of the material handling frame 54 away from the pressurizing frame 53, and a buffer is provided between the material handling frame 54 and the negative pressure suction plate 55. The negative pressure suction plate 55 is used to pick up the pressure strip from the material handling position 315 of the transfer table 31. The negative pressure suction plate 55 is connected to a vacuum generator (not shown in the figure), which creates negative pressure.

[0037] Reference Figure 1 and 7 According to the debugging and setting program, the fixed frame 51 and the sliding frame 10 cooperate to perform addressing and positioning adjustments in the X and Y axis directions. After debugging, the fixed frame 51 drives the pressurizing device to move to the material picking position 315 of the transfer table 31. The negative pressure suction plate 55 picks up the pressure strip located at the material picking position 315, causing the pressure strip to move with the movement of the fixed frame 51 until it moves above the battery pack. The pressure strip is aligned with the shoulder position of the battery pack to be installed. The pressurizing drive 52 controls the pressurizing frame 53 and the material picking frame 54 to move downward along the Z axis. After the pressure strip abuts against the battery pack, the pressurizing drive 52 continues to apply pressure, so that the pressure strip and the battery pack achieve a relatively stable connection and installation. When the transfer mechanism 3 in this technical solution is selected, the moving distance of the material picking mechanism 5 along the Y axis direction remains consistent each time, and the accuracy is easier to control.

[0038] Reference Figure 7 In order to accommodate multiple blueprints of pressure strips, the material picker 54 is equipped with a quick changer 56 to facilitate quick changes in the size of the negative pressure suction plate 55.

[0039] Reference Figure 1 and 7The material handling mechanism 5 also includes a tightening device 57, which includes a tightening head 571, a tightening gun body 572, and a nail storage chamber 573. The tightening gun body 572 is fixedly connected to the pressure frame 53. The tightening head 571 is located at the end of the tightening gun body 572, and the nail storage chamber 573 is located on the tightening gun body 572. The tightening gun body 572 moves synchronously with the pressure frame 53 as it is pressed down, connecting the screws in the nail storage chamber 573 to the connecting screw holes of the pressure bar through the tightening head 571, thereby achieving automatic threaded connection.

[0040] Reference Figure 1 , 2 7. The pressurizing device also includes a screw-on mechanism 6, which is located on one side of the mounting truss 1. The screws stored in the screw-on mechanism 6 are transferred to the screw storage compartment 573 through an air blowing pipe (not shown in the figure) for use by the tightening device 57.

[0041] Embodiment 1 of this application also discloses an installation process for a pressure device that automatically installs pressure strips, including the following steps: S1: The AGV trolley carries the battery pack into the station and is positioned below the installation truss 1. The AGV trolley carries the pressure strip from the material warehouse and places the pressure strip in the material storage mechanism 2. The material storage mechanism 2 is equipped with several positioning fixtures to keep the pressure strip in a stable position. S2: The cooperating mechanism 4 grabs the pressing strip through the sponge suction cup 423 and places it in the material feeding position 314 of the transfer table 31; S3: Positioning device 32 adjusts the positioning of the pressure strip on the transfer table 31; S4: The conveying device 33 operates, and the lifting plate 332 is driven to lift by the first driving member 331, which lifts the pressure bar. Then the second driving member 334 drives the moving plate 335 to move, and moves the pressure bar to the material picking position 315. S5: The material handling mechanism 5 moves to pick up the pressure bar that has moved to the material handling position 315 and transfers it to the shoulder position of the module inside the battery pack; S6: The pressure drive 52 operates, moving the pressure bar along the Z-axis to the module shoulder inside the battery pack, and then continuously applying pressure to achieve pressure installation of the pressure bar and the battery pack; S7: As the pressure frame 53 presses down, the tightening device 57 connects the pressure strip to the battery pack using screws. Simultaneously, the cooperating mechanism 4 cyclically grabs the pressure strip and places it at the material release position 314 of the transfer table 31 for transport by the conveying device 33. S8: The material handling mechanism 5 moves in a cycle, and each time it picks up the pressure strip at the material handling position 315 of the transfer table 31 and installs and pressurizes it. Example

[0042] The differences between Example 2 and Example 1 are as follows: Figure 2 and 8The transfer mechanism 3 includes a fixed platform 34, a shuttle drive device 37, a first shuttle plate 35, and a second shuttle plate 36. The shuttle drive device 37 is located inside the fixed platform 34. The first shuttle plate 35 and the second shuttle plate 36 are each equipped with a positioning device 32 for placing pressure strips. The shuttle drive device 37 is used to drive the first shuttle plate 35 and the second shuttle plate 36 to exchange positions along the Y-axis and Z-axis directions.

[0043] Reference Figure 8 and 9 The shuttle drive device 37 includes a shuttle motor 371, a shuttle belt 372, a shuttle connecting plate 38, and a limiting plate 343. The shuttle motor 371 is fixedly connected to the bottom of the fixed platform 34. A rotating shaft 344 is rotatably connected to the fixed platform 34. The shuttle belt 372 is wound around the rotating shaft 344, and one of the rotating shafts 344 is connected to the output end of the shuttle motor 371. A first connecting part 351 is fixedly connected to the first shuttle plate 35, and the first connecting part 351 is fixedly connected to the shuttle belt 372. A shuttle connecting part 381 is fixedly connected to the shuttle connecting plate 38, and the shuttle connecting part 381 is fixedly connected to the shuttle belt 372. A fixed upright plate 341 is fixedly connected to the fixed platform 34 in the vertical direction. Guide slides 342 are provided on both sides of the fixed upright plate 341. The first shuttle plate 35 and the shuttle connecting plate 38 are symmetrically slidably connected to the opposite sides of the fixed upright plate 341 through the guide slides 342.

[0044] Reference Figure 8 and 9 The shuttle plate 38 is provided with several guide sleeves 382, ​​and the second shuttle plate 36 is fixedly connected with several guide rods 361. The guide sleeves 382 are for the guide rods 361 to pass through. The limiting plate 343 is fixedly connected to the fixed platform 34. The limiting plate 343 is provided with a V-shaped limiting groove 3431 along the Y-axis. The second shuttle plate 36 is fixedly connected with a sliding connecting part 362. The sliding connecting part 362 passes through the V-shaped limiting groove 3431 and moves along the V-shaped groove track of the V-shaped limiting groove 3431.

[0045] Reference Figure 8 and 9 When the shuttle motor 371 runs, it drives the rotating shaft 344 to move the shuttle belt 372. The shuttle belt 372 drives the first shuttle plate 35 and the shuttle connecting plate 38 to move synchronously relative to each other along the Y-axis. As the shuttle connecting plate 38 moves, the second shuttle plate 36 moves synchronously under the action of the guide sleeve rod 361. Since the sliding connection part 362 passes through the V-shaped limiting groove 3431, the second shuttle plate 36 moves along the Y-axis while simultaneously moving up and down in the Z-axis direction.

[0046] Reference Figure 8 and 9In order to improve the positional stability of the second shuttle plate 36 when it is stationary, parking slots 3432 are extended at both ends of the V-shaped limiting groove 3431.

[0047] When the material handling mechanism 5 cooperates with the transfer mechanism 3 of Embodiment 2, the first shuttle plate 35 is filled with pressure strips. The material handling mechanism 5 moves back and forth multiple times along the Y-axis. The distance of each movement of the material handling mechanism 5 is not the same and needs to be set according to the placement position of the pressure strips on the first shuttle plate 35. After reaching the corresponding pressure strip position, it drives the negative pressure suction plate 55 to pick up the pressure strips in sequence. After the pressure strips on the first shuttle plate 35 are removed, the shuttle drive device 37 drives the first shuttle plate 35 and the second shuttle plate 36 to switch positions, and the material handling mechanism 5 repeats the operation to pick up the pressure strips on the second shuttle plate 36 in sequence. The transfer table 31 using this technical solution has a simpler overall structure, is more convenient to use, and is also simpler and more convenient to maintain and replace parts, which can also significantly reduce costs.

[0048] Embodiment 2 of this application also discloses an installation process for a pressure device that automatically installs pressure strips, including the following steps: S1: The AGV trolley carries the battery pack into the station and carries the pressure bar and places the pressure bar at the incoming material temporary storage mechanism 2; S2: The cooperating mechanism 4 grabs the pressure strip and places it on the first shuttle plate 35. The cooperating mechanism 4 moves the pressure strips in sequence until the first shuttle plate 35 is full. S3: Positioning device 32 adjusts the positioning of the pressure strip on the first shuttle plate 35; S4: The material picking mechanism 5 moves along the Y-axis, picks up the pressure strip located on the first shuttle plate 35 and drives the pressure strip to move, aligns the pressure strip with the shoulder position of the module inside the battery pack and presses it in place. After the pressure strip is placed in place, pressure is continuously applied to realize the pressure installation between the pressure strip and the battery pack.

S9: The material handling mechanism 5 continues to handle the material from the second shuttle plate 36, and simultaneously, the cooperating mechanism 4 grabs the material handling bar on the incoming material storage mechanism to fill the first shuttle plate 35. Example

[0049] The difference between Embodiment 3 and Embodiment 1 is that an engineering plastic strip can also be used. This type of strip does not require screw connection and can be connected to the battery pack by adhesive. The positioning device 32 needs to be adapted and changed according to the selection of the strip. The positioning device 32 also includes a positioning baffle, which is fixedly connected to the side of the positioning block 321 that is far apart from each other. The cooperating mechanism 4 moves the strip into the positioning clamp 322, and the positioning baffles on both sides limit and fix the strip in the length direction.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
