Description

Technical Field

[0001] The present invention relates to the technical field of power battery gluing processing, and particularly to a four-channel power battery gluing production line. Background Art

[0002] In recent years, the state has strongly encouraged and supported the development of new energy technologies. The demand for new energy power batteries from many manufacturers has increased significantly, which brings great development opportunities to power battery manufacturers. Lithium secondary battery packs with high energy density, high operating voltage, good storage characteristics and life characteristics are widely used as energy sources for various types of mobile devices and various electronic products. During the processing of power battery modules, it is often necessary to perform gluing operations on the surface of each power battery block.

[0003] In the prior art, each process is generally carried out separately. During gluing, manual operation is mainly used, which consumes a large amount of human resources, has low production capacity, high production costs, and when the battery cells are manually operated, they inevitably come into contact with workers, and it is easy to leave contaminants such as sweat on the battery cells, which is prone to quality problems; moreover, the existing mechanical equipment has a low degree of automation, resulting in poor consistency and stability of battery quality, low yield rate, and the need to stop the machine for material change, affecting production efficiency and too high production costs. To solve the above problems, the Chinese Utility Model Patent (Authorized Publication No.: CN 206619657 U, Authorization Publication Date: November 7, 2017) discloses a power battery automatic gluing, bending, and buckling retainer device.

[0049] Compared with the prior art, the beneficial effects of the present invention are:

[0050] 1. The structure of the present invention is reasonably designed. By reasonably setting the lifting and grasping manipulator assembly, the power battery clamping, variable pitch and placement mechanism, the battery block conveying mechanism, the battery block clamping and positioning mechanism, the film storage assembly, the film pushing assembly, and the rubber suction mechanism, the overall equipment is long and narrow and compact, occupying a small space in the width direction, and is more suitable for installation in a long and narrow factory building;

[0051] 2. The structure design of the battery block clamping and positioning mechanism is reasonable, and it can be assembled tightly with the battery block conveying mechanism, greatly reducing the space occupation. The lateral clamping finger cylinder acts, and the lateral clamping block of the lateral clamping arm plate clamps one pair of side walls of the battery block. At the same time, the longitudinal clamping finger cylinder acts, and the longitudinal clamping block of the longitudinal clamping arm plate clamps the other pair of side walls of the battery block, thus completing the positioning of the battery block.

[0052] Through the cooperation of the glue sucking mechanism and the film tearing mechanism, the film with a release film can be automatically torn, so as to facilitate the subsequent film pasting operation.

[0053] 3. The variable pitch telescopic element in the present invention is arranged in parallel with the vertical variable pitch seat frame. The variable pitch telescopic element does not occupy the width space, and the overall structure design is compact. The lateral variable pitch sliding seat is directly installed on the front side wall at the upper end of the vertical variable pitch seat frame by means of transverse sliding fit, without an additional auxiliary guiding mechanism. While the mechanism runs smoothly and reliably, the overall assembly cost is relatively lower. Through the linkage cooperation between the variable pitch telescopic element, the two lateral variable pitch sliding seats, the corresponding sliding blocks and the two groups of limiting parts, the adjustment of the distance between the two battery blocks can be realized, and the operation is convenient.

[0054] 4. The alignment conveying and storage mechanism is arranged below the battery block conveying mechanism. The horizontal translation and flipping manipulator mechanism is used to grab, horizontally translate and flip the battery block. Then, the lifting linear mechanism pushes the docking conveying mechanism to rise so that it can receive the battery block. Finally, it docks with the alignment conveying and storage mechanism to complete the stacking and storage of the battery blocks, which can make the whole equipment more compact, the overall shape is long and narrow, reducing the space occupation in the width direction, and the storage process does not require manual participation, and the production operation efficiency is relatively higher.

Detailed implementation

[0080] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0081] Please refer to Figures 1 to 18 , a four-channel power battery gluing production line, including a middle platform 600. A pair of left and right symmetrically arranged chassis platforms 100 are arranged behind the middle platform 600. In the space between the chassis platform 100 and the middle platform 600, a tray conveyor chain 900 for transporting the battery block tray 800 is arranged in parallel. It also includes:

[0082] A pair of left and right symmetrically arranged battery block conveying mechanisms 1. The two ends of the battery block conveying mechanism 1 are respectively installed on the middle platform 600 and the chassis platform 100. The battery block conveying mechanism 1 has two belt conveying components for transporting the battery block 300;

[0083] The middle transfer rack 601 installed on the middle platform 600. A pair of lifting and grasping manipulator components are slidably installed on the middle transfer rack 601. The middle transfer rack 601 is also installed with a lateral linear module 602 for driving the transfer of the lifting and grasping manipulator components. The lifting and grasping manipulator components have two pneumatic clamping jaw cylinders 703 for grasping the battery blocks 300 on the battery block tray 800 at intervals. The lifting and grasping manipulator components are also used to rotate and adjust the posture of the battery block 300;

[0084] A pair of power battery clamping, variable-spacing and placing mechanisms 7 installed on the middle platform 600. The power battery clamping, variable-spacing and placing mechanisms 7 have two pneumatic clamping jaw cylinders 76 for grasping the battery blocks 300 after posture adjustment. The power battery clamping, variable-spacing and placing mechanisms 7 also adjust the battery blocks 300 from the vertical state to the horizontal state, and perform variable-spacing adjustment on the two battery blocks 300, and place the battery blocks 300 after variable-spacing on the battery block conveying mechanism 1;

[0085] The battery block clamping and positioning mechanism 2 installed on the chassis platform 100 is used to clamp and position the battery blocks 300 on the battery block conveying mechanism 1;

[0086] The film storage component 5 installed at the end of the chassis platform 100 is used to store the stacked films 400;

[0087] The film pushing component installed inside the chassis platform 100 is used to gradually push the stacked films 400 upward;

[0088] The longitudinal transfer gantry 200 installed on the chassis platform 100 has a suction rubber mechanism 3 slidably installed on the longitudinal guide rail 201 of the longitudinal transfer gantry 200. The suction rubber mechanism 3 is used to suck the film 400 and transfer the film 400 to the upper surface of the battery block 300 for sticking the film.

[0089] As a further solution, please refer to Figures 15 to 18 , in order to facilitate the transfer and stacking storage of the battery blocks 300 after sticking the film, the present invention further includes: a transverse moving and flipping manipulator mechanism 8 installed on the longitudinal transfer gantry 200. The transverse moving and flipping manipulator mechanism 8 is used to grab the battery blocks 300 that have completed sticking the film on the battery block conveying mechanism 1, and also adjust the battery blocks from a lying state to an upright state;

[0090] The lifting and docking conveyor mechanism 9 includes a lifting linear mechanism installed on the chassis platform 100 and a docking conveyor mechanism for receiving the battery blocks 300. The docking conveyor mechanism is also used to dock with the alignment conveying and storage mechanism 500 under the drive of the lifting linear mechanism.

[0091] The working principle of the present invention is: in this embodiment, eight battery blocks 300 are stacked and inserted on each battery block tray 800, and the battery block trays 800 with the battery blocks 300 inserted are transported through the tray conveying chain 900;

[0092] When the battery block tray 800 is transported to the middle part of the tray conveying chain 900, the lifting and grabbing manipulator assembly on the middle transfer rack 601 walks to the directly above the battery block tray 800 under the push of the grabbing manipulator transverse linear module 602. Then, the lifting and grabbing manipulator assembly uses two grabbing pneumatic gripper cylinders 703 to respectively grab the first and fourth power batteries 300. Then, the lifting and grabbing manipulator assembly also rotates and adjusts the posture of the battery block 300 to make it convenient for the subsequent pneumatic gripper cylinder 76 to grab;

[0093] Next, the two pneumatic gripper cylinders 76 of the power battery gripping and variable-spacing placement mechanism 7 grip the battery block 300 after the posture adjustment. Then, the power battery gripping and variable-spacing placement mechanism 7 also adjusts the battery block 300 from the upright state to the lying state, performs variable-spacing adjustment on the two battery blocks 300, and places the battery blocks 300 after variable-spacing adjustment on the battery block conveying mechanism 1;

[0094] Next, the battery block conveying mechanism 1 conveys the battery block 300 to the gripping station of the battery block gripping and positioning mechanism 2. The battery block gripping and positioning mechanism 2 clamps the battery block 300, thereby realizing the positioning of the battery block 300. At the same time, the glue suction mechanism 3 sucks the film 400 from the film storage component 5, and then places the sucked film 400 on the battery block 300 for glue pasting operation. After the glue pasting of the battery block 300 is completed, the belt conveying component 13 of the battery block conveying mechanism 1 continues to start, and the power battery 300 after glue pasting is transported to the end of the battery block conveying mechanism 1; and the next group of battery blocks 300 will be transported to the gripping station of the battery block gripping and positioning mechanism 2, and so on repeatedly to realize the automatic glue pasting operation of the battery blocks 300;

[0095] Finally, the transverse translation and flipping manipulator mechanism 8 grabs the battery block 300 after glue pasting on the battery block conveying mechanism 1, also adjusts the battery block 300 from the lying state to the upright state, and transfers the battery block 300 to directly above the lifting and docking conveying mechanism 9;

[0096] The docking conveying mechanism approaches the battery block 300 under the drive of the lifting linear mechanism. The transverse translation and flipping manipulator mechanism 8 releases the battery block 300, so that the battery block 300 can fall on the docking conveying mechanism;

[0097] Then, the lifting linear mechanism drives the docking conveying mechanism to dock with the alignment conveying and storage mechanism 500, and the battery blocks 300 can be pushed into the alignment conveying and storage mechanism 500 in sequence for stacking and warehousing.

[0098] As a specific solution of the present invention, please refer to Figures 9 to 11 , the battery block conveying mechanism 1 includes a conveying machine frame 11 and a conveying motor 12. The conveying machine frame 11 is fixedly installed on the chassis platform 100. Two groups of belt conveying mechanisms are installed on the conveying machine frame 11. Multiple groups of limit frames 14 for limiting the battery block 300 are distributed and installed on the belts of each group of belt conveying mechanisms. The conveying motor 12 is installed at the end of the conveying machine frame 11, and the output end of the conveying motor 12 is docked with the driving shaft of the belt transmission mechanism.

[0099] The working principle of the battery block conveying mechanism 1 is as follows: The belt conveying mechanism is driven by the conveying motor 12 to transport the battery block 300. The battery block 300 is initially limited by the limiting frame 14, so that the subsequent battery block clamping and positioning mechanism 2 can stably clamp the battery block 300.

[0100] The battery block clamping and positioning mechanism 2 includes a U-shaped clamping frame plate 21, a longitudinal clamping finger cylinder 22, a clamping lifting cylinder 23, and a transverse clamping finger cylinder 24. The U-shaped clamping frame plate 21 is fixedly installed on the chassis platform 100 and is located below the conveying machine frame 11;

[0103] The working principle of the battery block clamping and positioning mechanism 2 is as follows: The structure of the battery block clamping and positioning mechanism 2 is reasonably designed and can be compactly assembled with the battery block conveying mechanism 1, greatly reducing the space occupation;

[0104] When the battery block 300 is transported to the preset position, the clamping lifting cylinder 23 contracts, so that the height of the transverse clamping finger cylinder 24 corresponds to that of the battery block 300. Then, the transverse clamping finger cylinder 24 acts, and one pair of side walls of the battery block 300 are clamped by the transverse clamping block 251 of the transverse clamping arm plate 25;

[0105] At the same time, the longitudinal clamping finger cylinder 22 acts, and the other pair of side walls of the battery block 300 are clamped by the longitudinal clamping block 261 of the longitudinal clamping arm plate 26, so as to complete the positioning of the battery block 300.

[0106] As a further solution of the present invention, please refer to Figure 12The film storage assembly 5 includes a bottom machine base plate 53, on which four storage bases 51 are distributed and installed, each storage base 51 has a through hole in the middle, and a plurality of guide rod frames 52 are distributed and installed on the upper end surface of the storage base 51, and a storage space for stacking films 400 is formed between the guide rod frames 52;

[0107] The film pushing assembly includes an electric push rod 54 fixedly mounted on the lower end surface of the bottom machine base plate 53, and a push seat plate 55 is fixedly mounted on the telescopic end of the electric push rod 54. The push seat plate 55 is used to pass through the through hole and contact the bottommost film 400.

[0108] The working principle of the film storage component 5 and the film pushing component is: through the gradual extension of the electric push rod 54, the stacked films 400 can be pushed to move gradually upward, so that the glue suction mechanism 3 can stably absorb the top layer of film 400 at a set height position.

[0109] See also Figure 14 The glue suction mechanism 3 includes a glue suction linear module installed on the longitudinal transfer gantry 200, a glue suction seat plate 31 is installed at the movable end of the glue suction linear module, a glue suction lifting cylinder 32 is fixedly installed at the lower end of the glue suction seat plate 31, and a pair of suction cup assemblies 33 for sucking the film 400 are installed at the telescopic end of the glue suction lifting cylinder 32.

[0110] The working principle of the glue suction mechanism 3 is as follows: when it is necessary to suck the film 400, the suction cup assembly 33 is transported to the top of the film storage assembly 5 under the push of the glue suction linear module, and then the glue suction lifting cylinder 32 is extended to make the suction cup assembly 33 rest against the top film 400, and then negative pressure adsorption is performed to adsorb the film 400, and then, after the glue suction lifting cylinder 32 contracts, the glue suction linear module can transport the adsorbed film 400 toward the battery block 300.

[0111] In order to enable the solution of the present invention to tear off the film 400 with the release film, please refer to Figure 13 The present embodiment further includes a film-tearing mechanism 6, which includes a material-guiding cover 61, a film-tearing frame 61, a film-tearing lifting cylinder 64, a film-peeling cylinder 65, and a pneumatic clamp 66 for clamping the release film strip. The material-guiding cover 61 is fixedly mounted on the chassis platform 100, and a collecting box 62 is also installed inside the chassis platform 100, and the collecting box 62 is located below the material-guiding cover 61;

[0112] A film tearing frame 63 fixedly mounted on the bottom frame platform 100 is provided at the notch of the material guide cover 61, a film tearing lifting cylinder 64 is fixedly mounted on the lower end of the film tearing frame 63, a transverse seat plate 641 is fixedly mounted on the telescopic end of the film tearing lifting cylinder 64, and the transverse seat plate 641 is slidably matched on the film tearing frame 642;

[0113] The two ends of the transverse seat plate 641 are installed with inclined film peeling cylinders 65 through oblique brackets 642. The telescopic end of each film peeling cylinder 65 is fixedly installed with a film peeling seat plate 651. The two ends of the film peeling seat plate 651 are installed with pneumatic clamps 66.

[0114] The working principle of the film tearing mechanism 6 is as follows: when the film 400 is transported to the film tearing station, the pneumatic clamping claw 66 clamps the release film strip, then the inclined film peeling cylinder 65 contracts to complete the film tearing operation, then the film tearing lifting cylinder 64 contracts to completely separate the release film from the film 400, and finally, the pneumatic clamping claw 66 is released, and the release film can fall into the collection box 62 at the bottom;

[0115] The film 400 after tearing off the film can be transported toward the battery block 300, and finally, the film pasting operation is completed.

[0116] To ensure that the film 400 can be stably attached to the surface of the battery block 300, please refer to Figure 9 This embodiment also includes a glue pressing mechanism 4, which includes a glue pressing linear module installed on the longitudinal transfer gantry 200, and a glue pressing seat plate 41 is installed at the movable end of the glue pressing linear module, and a pair of glue pressing brackets 43 are fixedly installed at the lower end of the glue pressing seat plate 41, and a glue pressing seat 44 for pushing the glue sheet 400 is installed at the bottom of the glue pressing bracket 43; a visual camera 42 for photographing the battery block 300 is also installed on the glue pressing seat plate 41.

[0117] The working principle of the glue pressing mechanism 4 is as follows: after the suction cup assembly 33 initially attaches the film 400 to the upper surface of the battery block 300, the glue pressing seat 44 at the lower end of the glue pressing bracket 43 is used to press the film 400 under the push of the glue pressing linear module, thereby squeezing out the bubbles between the film 400 and the battery block 300 to ensure a good attachment effect.

[0118] A visual camera 42 for photographing the battery block 300 is also installed on the glue-bonded seat plate 41. The visual camera 42 photographs the battery block 300 after glue bonding, so as to control defective products through visual algorithms.

[0119] As a specific solution of the present invention, please refer to Figures 2 to 3 The lifting and grabbing manipulator assembly includes a lifting and grabbing linear module 603 fixedly mounted on the driving end of the grabbing manipulator transverse linear module 602 and a grabbing manipulator assembly 700;

[0120] The grabbing manipulator assembly 700 includes a grabbing frame base plate 701, which is fixedly mounted on the driving end of the grabbing lifting linear module 603, and adapters are rotatably mounted on both ends of the lower end surface of the grabbing frame base plate 701, and a grabbing pneumatic clamping claw cylinder 703 is fixedly mounted on the lower end of the adapter;

[0121] At both ends of the upper end surface of the grasping frame seat plate 701, a rotary drive motor 702 is fixedly installed, and the output end of the rotary drive motor 702 is docked with the central axis of the adapter seat.

[0122] The working principle of the lifting and grasping manipulator assembly is as follows: Driven by the lifting linear module 603 for grasping, the grasping manipulator assembly 700 descends, so that the grasping pneumatic gripper cylinder 703 approaches the battery block 300 on the battery block tray 800. Then, the two grasping pneumatic gripper cylinders 703 clamp the first and fourth battery blocks 300.

[0123] Next, the lifting linear module 603 for grasping drives the grasping pneumatic gripper cylinder 703 to rise. Then, the rotary drive motor 702 is started to drive the grasping pneumatic gripper cylinder 703 and the battery block 300 to rotate, completing the attitude adjustment of the battery block 300.

[0124] Driven by the grasping manipulator transverse linear module 602, the grasping pneumatic gripper cylinder 703 and the battery block 300 are transferred to the working station of the power battery clamping and variable pitch placement mechanism 7.

[0125] As a specific solution of the present invention, please refer to Figures 4 to 7 , the power battery clamping and variable pitch placement mechanism 7 includes a vertical variable pitch seat frame 74, a variable pitch telescopic element 77, a pair of transverse variable pitch sliding seats 75 and a pair of pneumatic gripper cylinders 76. The upper front side wall of the vertical variable pitch seat frame 74 is horizontally slidably fitted with a transverse variable pitch sliding seat 75, and a variable pitch telescopic element 77 is docked and installed between the two transverse variable pitch sliding seats 75;

[0126] A sliding block 751 is fixedly installed on each transverse variable pitch sliding seat 75. Two groups of limiting members are fixedly installed on the upper end of the vertical variable pitch seat frame 74. Each group of limiting members includes a pair of limiting stop bars 741 for limiting the position of the sliding block 751;

[0127] A vertical support seat 752 is fixedly installed at the lower end of each transverse variable pitch sliding seat 75, and a pneumatic gripper cylinder 76 for clamping the battery block 300 is installed at the lower end of the vertical support seat 752.

[0128] In the present invention, the variable pitch telescopic element 77 is arranged in parallel with the vertical variable pitch seat frame 74. The variable pitch telescopic element 77 does not occupy the width space, and the overall structure design is compact. In addition, the transverse variable pitch sliding seat 75 is directly horizontally slidably fitted and installed on the upper front side wall of the vertical variable pitch seat frame 74, without an additional auxiliary guiding mechanism. While the mechanism runs smoothly and reliably, the overall assembly and assembly cost is relatively lower.

[0129] Among them, in order to adjust the clamping posture of the battery block 300, a cylinder end seat is installed at the end of the pneumatic gripper cylinder 76. The cylinder end seat is rotationally and movably connected to the lower end of the vertical support seat 752 through a seat rotating shaft. A deflection driving element 753 for driving the rotation of the seat rotating shaft is fixedly installed on the side wall of the vertical support seat 752. Obviously, the deflection driving element 753 adopts a motor or a deflection cylinder, and the variable pitch telescopic element 77 adopts a telescopic cylinder or an electric telescopic rod.

[0130] In the initial state, the pneumatic gripper cylinder 76 can be in a horizontal state. When the grasping pneumatic gripper cylinder 703 releases the battery block 300 and resets, under the drive of the deflection driving element 753, the pneumatic gripper cylinder 76 rotates around the seat rotating shaft, so that the clamped battery block 300 is converted from a vertical state to a horizontal state, which is beneficial to placing the battery block 300 on the subsequent battery block conveying mechanism 1 later.

[0131] The power battery clamping, variable pitch and placing mechanism 7 further includes a lifting side wall plate 73 and a lifting telescopic element 731 fixedly installed at the lower end of the lifting side wall plate 73. The vertical variable pitch seat frame 74 is vertically slidably and movably installed on the front side wall of the lifting side wall plate 73. The telescopic end of the lifting telescopic element 731 is docked with the middle part of the vertical variable pitch seat frame 74. Obviously, the lifting telescopic element 731 adopts a telescopic cylinder or an electric telescopic rod.

[0132] The power battery clamping, variable pitch and placing mechanism 7 further includes a forward moving push seat plate 732, a bottom support seat plate 71 and a forward moving telescopic element 72. The lower end of the lifting side wall plate 73 is fixedly docked with the forward moving push seat plate 732. The forward moving push seat plate 732 is slidably and movably installed on the bottom support seat plate 71 in the front-back direction. The bottom support seat plate 71 is specifically fixedly installed on the middle platform 600. A forward moving telescopic element 72 is fixedly installed on the bottom support seat plate 71. The telescopic end of the forward moving telescopic element 72 is docked with the forward moving push seat plate 732.

[0133] The working principle of the power battery clamping, variable pitch and placing mechanism 7 is as follows: When the grasping pneumatic gripper cylinder 703 and the battery block 300 are transferred to the working position of the power battery clamping, variable pitch and placing mechanism 7, the forward moving telescopic element 72 extends, so that the pneumatic gripper cylinder 76 approaches the corresponding battery block 300;

[0134] Then, the pneumatic gripper cylinder 76 is started and closed to clamp the battery block 300. Then, the grasping pneumatic gripper cylinder 703 releases the battery block 300 and resets under the drive of the grasping manipulator transverse linear module 602;

[0135] Then, under the drive of the deflection driving element 753, the pneumatic gripper cylinder 76 rotates around the seat rotating shaft, so that the clamped battery block 300 is converted from a vertical state to a horizontal state;

[0136] Next, the variable pitch telescopic element 77 is activated and extended. Under the limitation of the two outer limit bars 741, the distance between the two lateral variable pitch sliding seats 75 reaches the maximum, that is, the distance between the two battery blocks 300 reaches the maximum, so as to adjust the distance between the two battery blocks 300.

[0137] After the distance adjustment is completed, the lifting telescopic element 731 is activated and contracted, which can drive the vertical variable pitch seat frame 74 to move downward along the lifting side wall plate 73, and then the battery block 300 can be placed on the battery block conveying mechanism 1.

[0138] As a further solution of the present invention, please refer to Figure 17 , the transverse translation and flipping manipulator mechanism 8 includes a longitudinal transfer gantry 200 installed on the chassis platform 100, a transfer machine base plate 82 slidably installed on the longitudinal transfer gantry 200, a flipping outer bracket 83, a flipping inner bracket, and a pair of flipping pneumatic jaw cylinders 86 for clamping the battery block 300. A transverse translation driving element 81 for driving the transverse translation of the transfer machine base plate 82 is installed on the longitudinal transfer gantry 200. A flipping outer bracket 83 is installed on the transfer machine base plate 82. The lower end of the flipping outer bracket 83 is rotatably installed with a flipping inner bracket. The flipping outer bracket 83 is also installed with an inner bracket rotation driving mechanism for driving the rotation of the flipping inner bracket. The flipping pneumatic jaw cylinders 86 are distributed and installed on the flipping inner bracket;

[0139] The flipping outer bracket 83 is vertically slidably and cooperatively installed on the side wall of the transfer machine base plate 82 away from the longitudinal transfer gantry 200. The upper end of the transfer machine base plate 82 is also fixedly installed with a bracket lifting driving element 831 for docking with the flipping outer bracket 83;

[0140] In order to reduce the occupation of the flipping space by the flipping inner bracket, the flipping inner bracket includes a bracket rotating shaft 85 and a U-shaped flipping bracket 851 fixed on the bracket rotating shaft 85. The two ends of the bracket rotating shaft 85 are rotatably and cooperatively connected with the lower end of the flipping outer bracket 83. The flipping pneumatic jaw cylinders 86 are distributed and installed on the inner side wall of the U-shaped flipping bracket 851, and the flipping clamping arms of the flipping pneumatic jaw cylinders 86 have through holes for allowing the bracket rotating shaft 85 to pass through; through the above structural design, the installation and arrangement of the entire flipping pneumatic jaw cylinder 86 are compact, and the occupation of the flipping space is relatively small.

[0141] The inner bracket rotation drive mechanism includes an inner bracket rotation drive motor 84 installed on the flipping outer bracket 83. The output end of the inner bracket rotation drive motor 84 is drivingly connected to the end of the bracket rotating shaft 85 through a belt drive assembly. The working principle of flipping the inner bracket is as follows: The inner bracket rotation drive motor 84 drives the bracket rotating shaft 85 to rotate through the belt drive assembly, and the bracket rotating shaft 85 can synchronously drive the U-shaped flipping bracket 851 and the flipping pneumatic gripper cylinder 86 to perform a flipping action, so that the battery block 300 is adjusted from a horizontal state to a vertical state.

[0142] The working principle of the transverse movement and flipping manipulator mechanism 8 is as follows: The transverse movement drive element 81 drives the transfer machine base plate 82 to move along the longitudinal transfer gantry 200, so that the flipping pneumatic gripper cylinder 86 moves to directly above the end of the battery block conveying mechanism 1. Then, the bracket lifting drive element 831 extends to drive the flipping outer bracket 83, the flipping inner bracket, and the flipping pneumatic gripper cylinder 86 to descend, so that the flipping pneumatic gripper cylinder 86 approaches the battery block 300. Then, the flipping pneumatic gripper cylinder 86 grips the battery block 300, and the bracket lifting drive element 831 retracts. Then, the transverse movement drive element 81 drives the transfer machine base plate 82 to move in the reverse direction along the longitudinal transfer gantry 200;

[0143] When the transfer machine base plate 82 moves to the discharging station, the inner bracket rotation drive mechanism drives the flipping inner bracket to rotate, so that the battery block 300 is adjusted from a horizontal state to a vertical state. Then, the lifting linear mechanism drives the docking conveyor mechanism to rise to the receiving station, making it close to the battery block 300. Then, the flipping pneumatic gripper cylinder 86 releases the battery block 300, and the battery block 300 falls onto the docking conveyor mechanism. Then, the lifting linear mechanism drives the docking conveyor mechanism to descend to the docking station, so that the docking conveyor mechanism is flush-docked with the alignment conveying and storage mechanism 500. The docking conveyor mechanism and the alignment conveying and storage mechanism 500 start to work. The docking conveyor mechanism conveys the battery block 300 onto the alignment conveying and storage mechanism 500, and the alignment conveying and storage mechanism 500 can stack and input the battery block 300 to the end.

[0144] In the present invention, the alignment conveying and storage mechanism 500 is arranged below the battery block conveying mechanism 1. The transverse movement and flipping manipulator mechanism 8 is used to grab, horizontally move, and flip the battery block 300. Then, the lifting linear mechanism pushes the docking conveyor mechanism to rise so that it can receive the battery block 300. Finally, it is docked with the alignment conveying and storage mechanism 500 to complete the stacking and warehousing of the battery block 300, which can make the entire device more compact, overall in a long and narrow shape, reduce the space occupation in the width direction, and the warehousing process does not require manual participation, and the production operation efficiency is relatively higher.

[0145] As a specific solution of the present invention, please refer to Figure 18, the lifting linear mechanism includes a vertical lifting guide seat 91, a lifting drive motor 92, and a vertical lead screw 93. The vertical lifting guide seat 91 is fixedly installed on the chassis platform 100. A vertical lead screw 93 is rotatably installed on the vertical lifting guide seat 91. The lower end of the vertical lifting guide seat 91 is fixedly installed with a lifting drive motor 92. The output end of the lifting drive motor 92 is drivingly connected to the shaft end of the vertical lead screw 93;

[0146] The docking chassis seat 94 of the docking conveyor mechanism is vertically slidably installed on the vertical lifting guide seat 91, and the docking chassis seat 94 is drivingly connected to the vertical lead screw 93 through a nut seat.

[0147] The working principle of the lifting linear mechanism is: when the lifting drive motor 92 works, it will drive the vertical lead screw 93 to rotate. The vertical lead screw 91 drives the nut seat and the docking chassis seat 94 to rise or fall along the vertical lifting guide seat 91, so as to drive the docking conveyor mechanism to approach the battery block 300 below the flipping pneumatic gripper cylinder 86 or to be used for docking with the alignment conveying and storage mechanism 500.

[0148] Among them, the docking conveyor mechanism further includes a docking conveyor frame 951 and a docking conveyor belt assembly 952. The docking conveyor frame 951 is slidably installed on the docking chassis seat 94 in the front-back direction, and a forward docking drive mechanism for driving the docking conveyor frame 951 to move is further installed at the lower end of the docking chassis seat 94;

[0150] The forward docking drive mechanism includes a forward docking belt assembly 961 installed at the lower end of the docking chassis seat 94 and a forward drive motor 96 for driving the forward docking belt assembly 961 to operate.

[0151] Please refer to Figure 16 , the alignment conveying and storage mechanism 500 includes an alignment conveying frame 501 installed on the chassis platform 100 and an alignment conveying belt assembly 503 installed on the alignment conveying frame 501. An alignment conveying motor 502 for driving the alignment conveying belt assembly 503 to operate is further installed at the end of the alignment conveying frame 501;

[0152] A plurality of alignment gantries 504 are distributively installed on the alignment conveying rack 501. A plurality of connecting seat plates 505 are distributively fixed to the lower ends of each alignment gantry 504. The lower ends of the connecting seat plates 505 aligned in the conveying direction are jointly fixedly connected with an alignment guide plate 506. The alignment guide plate 506 divides the conveying space above the alignment conveying belt assembly 503 into a plurality of battery block conveying and storage channels. An end baffle 507 is also fixedly installed at the end of the alignment guide plate 506.

[0153] The working principle of the cooperation between the docking transfer mechanism and the alignment conveying and storage mechanism 500 is as follows: When the battery block 300 is placed on the docking transfer belt assembly 952, the lifting linear mechanism drives the docking transfer mechanism to descend, so that the docking transfer belt assembly 952 is flush with the alignment conveying belt assembly 503 in height. Then, the forward movement drive motor 96 works to drive the docking transfer rack 951 to move forward or backward, so that the docking transfer belt assembly 952 is aligned with one of the battery block conveying and storage channels. Next, the docking transfer motor 95 works to drive the docking transfer belt assembly 952 to operate. The belt of the docking transfer belt assembly 952 pushes the battery block 300 into the battery block conveying and storage channel. At the same time, the alignment conveying motor 502 works to drive the alignment conveying belt assembly 503 to operate. The belt of the alignment conveying belt assembly 503 pushes the incoming battery block 300 to the end of the battery block conveying and storage channel, completing the stacking and storage of the battery block 300.
