Technical Field

[0001] This invention belongs to the field of lithium battery technology, and in particular relates to a lithium battery assembly device. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the relatively active chemical properties of lithium metal, high requirements are undoubtedly placed on the production, packaging, and storage of lithium batteries.

[0003] The semi-finished lithium batteries produced need to be manually placed in storage containers during the assembly process. After the cover is placed on top of the container, it is pressed by a set pressing device, such as a cylinder or electric cylinder. During the assembly process, the low level of automation makes it difficult to neatly stack the batteries together, and the poor stability makes the whole assembly prone to loosening when subjected to external force.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figures 1-8 The diagram shows a structural representation of a lithium battery assembly device according to an embodiment of the present invention. The device includes a housing 1, a storage box 19, a support rod 2, a feeding mechanism 100, an adjusting mechanism 200, a rotating mechanism 300, and a clamping mechanism 400. The support rod 2 is installed in the middle of the housing 1, and a horizontal plate 4 is arranged at the top of the support rod 2. The feeding mechanism 100 is arranged between the support rod 2 and the horizontal plate 4 and is driven by an external motor to feed the tubular battery 6 to be assembled into the storage box 19. The adjusting mechanism 200 is installed inside the feeding mechanism 100 to clamp the tubular battery 6. The position of the storage box 19 within the feeding mechanism 100 is adjusted based on the rotation mechanism 300. The rotation mechanism 300 is rotatably mounted on the box body 1, and the free end of the rotation mechanism 300 is connected to the storage box 19. The storage box 19 slides along the box body 1 under the push of the rotation mechanism 300. The clamping mechanism 400 is installed at the bottom end of the horizontal plate 4. When the storage box 19 rotates to the position directly below the clamping mechanism 400, the execution end of the clamping mechanism 400 sends the external box cover 29 of the box body 1 to the top of the storage box 19, and the locking mechanism 500 at the bottom end of the storage box 19 fixes the position of the storage box 19 and the box cover 29.

[0040] In the specific implementation of this embodiment, the lithium battery assembly equipment has a high degree of automation. After the storage box 19 is placed in the box body 1, the feeding mechanism 100 and the adjusting mechanism 200 can automatically and neatly stack the tubular batteries 6 in the storage box 19 and seal the top of the storage box 19. It has high stability and can effectively prevent slippage when subjected to external force, thus improving the overall safety of the lithium battery.

[0041] In one embodiment of the present invention, during use, the feeding mechanism 100, in conjunction with the adjusting mechanism 200, places the tubular battery 6 into the storage box 19. After placement, the rotating mechanism 300 works to send the storage box 19 and the tubular battery 6 placed therein to the bottom of the clamping mechanism 400. At the same time, the clamping mechanism 400 sends the external box cover 29 to the top of the storage box 19 and connects the storage box 19 and the box cover 29 to prevent the assembled battery from becoming loose.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the feeding mechanism 100 includes a storage box 5 mounted on a horizontal plate 4 and a swing plate 9 mounted on the outside of the storage box 5.

[0043] The bottom of the storage box 5 is equipped with a pop-out component so that when the swing plate 9 is in a vertical state, the tubular battery 6 can be pushed into the swing plate 9.

[0044] The top of the swing plate 9 is equipped with a rotating shaft 10, which is connected to the shaft end of an external motor.

[0045] In the specific implementation of this embodiment, the pop-out component in this application consists of a telescopic component 7 and a push rod 8. In practical applications, the telescopic component 7 can be a linear drive device such as a cylinder or push rod. The number of columns arranged on the side of the push rod 8 is the same as that of the tubular battery 6, and they are arranged coaxially. When the swing plate 9 is in a vertical state, the telescopic component 7 pushes the push rod 8 to move, thereby pushing the tubular battery 6, which is located at the bottom of the storage box 5, outwards, so that it stops in the adjustment mechanism 200 provided inside the swing plate 9. The rotating shaft 10 rotates under the drive of an external motor, and the swing plate 9, the adjustment mechanism 200 provided inside the swing plate 9, and the tubular battery 6 clamped thereon move synchronously, rotating to the position shown in the attached drawings. Figure 1 The horizontal position shown.

[0046] like Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the adjustment mechanism 200 includes a lower abutment plate 12 and a movable plate 13 installed inside the swing plate 9, and a driving member 11 for moving the lower abutment plate 12 and the movable plate 13;

[0047] The adjacent drive components 11 are arranged in the same direction, and can be selected as lead screws and connected by a conveyor belt;

[0048] An upper abutment plate 14 is slidably arranged inside the movable plate 13. The upper abutment plate 14 and the lower abutment plate 12 are provided with corresponding slots 17. An abutment rod 15 is installed on the lower abutment plate 12. A spring 16 is sleeved in the middle of the abutment rod 15. One end of the spring 16 is connected to the upper abutment plate 14 and the other end is connected to the lower abutment plate 12.

[0049] The lower abutment plate 12 has grooves on both sides. When the lower abutment plate 12 slides to the bottom, the surface of the grooves fits against the swing plate 9.

[0050] In the specific implementation of this embodiment, the upper clamping plate 14 described in this application is slidably connected to the driving member 11. When the grooves on both sides of the lower clamping plate 12 are not in contact with the swing plate 9, the spring 16 pulls the lower clamping plate 12 and the upper clamping plate 14 to close them, thus clamping the tubular battery 6. During the process of the grooves on both sides of the lower clamping plate 12 contacting the swing plate 9 and continuing to descend, as shown in the attached drawings. Figure 5 As shown, as the lower abutment plate 12 and the movable plate 13 continue to descend, the abutment rod 15 pushes the upper abutment plate 14 to slide upward along the movable plate 13, allowing the upper abutment plate 14 to disengage from the lower abutment plate 12 and release the restraint on the tubular battery 6. In addition, a fixing post 18 is installed at the bottom of the horizontal plate 4 to prevent the tubular battery 6 from touching the horizontal plate 4 during swinging and causing damage to the main body. It can also directly push the adjusted tubular battery 6 out of the lower abutment plate 12 and the upper abutment plate 14, and the tubular battery 6 falls downward under the action of gravity.

[0051] like Figure 1 and Figure 6 As shown, in another preferred embodiment of the present invention, a positioning plate 20 is installed in the middle of the storage box 19, and the positioning plate 20 is slidably connected to the sliding tubular battery 6.

[0052] An interface 22 is installed on the inner wall of the storage box 19 at the position corresponding to the tubular battery 6, and a spring 21 is arranged on the side of the interface 22.

[0053] In the specific implementation of this embodiment, the bottom end of the second spring 21 is provided with a damper that cooperates with it. After the tubular battery 6 falls vertically through the positioning plate 20, it lands on the second spring 21. The second spring 21, in conjunction with the damper, can eliminate the vibration caused during the fall, prevent the tubular battery 6 from repeatedly bouncing in the height direction, and at the same time, prevent damage to the interface 22 during the fall.

[0054] like Figure 1 and Figure 6As shown, in another preferred embodiment of the present invention, the rotating mechanism 300 includes a transmission shaft 23 rotatably mounted in the upright 2, a rotating rod 24 mounted at the bottom end of the transmission shaft 23, and a drive motor 3 mounted at the top end of the transmission shaft 23.

[0055] The box 1 is provided with a groove for the storage box 19 and the rotating rod 24 to move;

[0056] The bottom edge of the storage box 19 is provided with a connecting groove 25 for the rotating rod 24 to be inserted into, so that the rotating rod 24 can be inserted into the storage box 19 and pulled to move.

[0057] In the specific implementation of this embodiment, after the tubular battery 6 falls into the storage box 19, the drive motor 3 works to drive the transmission shaft 23 to rotate, and through the set rotating rod 24, it drives the storage box 19 to slide in the horizontal plane, sending the storage box 19 to the bottom of the pressing mechanism 400.

[0058] like Figure 1 and Figure 7 As shown, in another preferred embodiment of the present invention, the clamping mechanism 400 includes an upper positioning post 26 and a lower positioning post 27 arranged sequentially at the bottom end of the horizontal plate 4, a plurality of swing rods 28 hinged to the side of the upper positioning post 26, and a telescopic member 30 installed on the lower positioning post 27 to push the swing rods 28 to swing.

[0059] The bottom end of the lower positioning column 27 is provided with a suction cup 32 for adsorbing the externally sent box cover 29. When the suction cup 32 is in contact with the upper surface of the box cover 29, the air is extracted by the air extraction device set inside the lower positioning column 27 to keep it from falling. The free end of the telescopic part 2 30 is provided with a limit block, which is slidably connected to the limit groove 31 arranged inside the swing rod 28.

[0060] A ball 34 is installed at the bottom end of the swing arm 28, and the ball 34 is slidably connected to the slide rail 33 provided on the box cover 29.

[0061] In the specific implementation of this embodiment, when in use, the suction cup 32 is used to adsorb the lid 29. When the lid 29 is placed, the telescopic member 30 pulls the swing rod 28 to swing along the bottom end of the upper positioning post 26, so that the ball 34 slides into the slide rail 33. During the swing of the swing rod 28, the lid 29 is pushed downward. When the locking mechanism 500 is embedded in the storage box 19, the ball 34 slides out of the slide rail 33 and the lid 29 is disengaged from the suction cup 32.

[0062] like Figure 1 , Figure 7 and Figure 8As shown, in another preferred embodiment of the present invention, the locking mechanism 500 includes a rod 35 fixedly installed at the bottom of the cover 29, a pawl 36 hinged to the side of the rod 35, a limiting rod 37 elastically installed in the pawl 36, and a spring 39 installed inside the pawl 36.

[0063] The insertion rod 35 is provided with a storage groove 40 for storing the claw 36;

[0064] The storage box 19 has a locking groove 38 for the limiting rod 37 to be inserted.

[0065] In the specific implementation of this embodiment, the insertion rod 35 moves synchronously with the box cover 29. As the insertion rod 35 slides into the storage box 19, the pawl 36 stays in the storage groove 40. When the insertion rod 35 slides to the lowest position, the pawl 36 swings outward under the push of the spring 39. When it swings to the outermost position, the limiting rod 37 pops out and embeds into the locking groove 38 to lock its position and prevent loosening when subjected to external force, which can effectively ensure the stability of the structure.

[0066] In summary, during use, the swing plate 9 remains in a vertical position. At this time, the lower clamping plate 12 and the upper clamping plate 14 are not in contact. The telescopic component 7 pushes the tubular battery 6 out through the push rod 8, allowing it to fall between the lower clamping plate 12 and the movable plate 13. While the swing plate 9 swings, the drive component 11 drives the lower clamping plate 12 and the movable plate 13 to move along the length of the swing plate 9. Under the action of the spring 16, the upper clamping plate 14 is pulled downward to the lower clamping plate 12, clamping the tubular battery 6. When plate 9 rotates to a horizontal position, the tubular battery 6 touches the fixing post 18, causing the tubular battery 6 to disengage from the clamping plates 12 and 14. The tubular battery 6 slides along the positioning plate 20 inside the storage box 19, and under the action of spring 21 and damper, the vibration caused by the tubular battery 6 falling is eliminated. After the above process is repeated several times, the tubular battery 6 is neatly arranged inside the storage box 19. At the same time, the drive shaft 23 drives the rotating rod 24 to rotate, causing the storage box 19 to slide along the box body 1, storing the batteries. The box 19 and the tubular battery 6 inside are placed directly below the suction cup 32. At this time, the external box cover 29 enters the box body 1, and the suction cup 32 adsorbs the box cover 29. The telescopic component 30 pulls the swing rod 28 to swing along the bottom end of the upper positioning post 26. At the same time, the ball 34 slides along the slide rail 33 set on the spring 39. When it slides out of the slide rail 33, the box cover 29 disengages from the suction cup 32. At the same time, the insertion rod 35 slides completely into the storage box 19, and the claw 36 swings outward under the action of the spring 39. When the limiting rod 37 is inserted into the locking groove 38, the positions of the insertion rod 35, the storage box 19 and the box cover 29 can be fixed. This lithium battery assembly equipment has a high degree of automation. After the storage box 19 is placed in the box body 1, the feeding mechanism 100 and the adjusting mechanism 200 can automatically and neatly stack the tubular batteries 6 in the storage box 19 and seal the top of the storage box 19. It has high stability and can effectively prevent slippage when subjected to external force, thus improving the overall safety of the lithium battery.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
