Description

Technical Field

[0001] The present invention relates to the technical field related to battery assembly, and in particular to a power lithium battery cap feeding device. Background Art

[0002] With the vigorous development and increasing maturity of the new energy vehicle industry, its market size continues to expand, and technological iterations are advancing rapidly. Consumers are demanding increasingly stringent requirements for the range, safety performance, and overall quality of new energy vehicles. Against this backdrop, the importance of power lithium batteries, a core component of new energy vehicles, has become increasingly prominent, and market demand for their use is increasing rapidly. Power lithium batteries are not only directly related to the range of new energy vehicles, but also have a profound impact on key performance indicators such as vehicle power output, charging efficiency, and service life. Therefore, their research and development, production, and application have become crucial links in the new energy vehicle industry chain.

[0003] In the production and manufacturing process of power lithium batteries, every tiny component is crucial, and together they ensure the overall performance and quality of the battery. Upon search, announcement number CN217134508U discloses a low-loss cap assembly moving device for battery cap assembly. This innovative design provides strong support for improving lithium battery production efficiency and yield. The device cleverly uses a moving mechanism to accurately move the vacuum adsorption parts, so that the vacuum adsorption parts can be flexibly switched between the material picking station and the loading station, thereby efficiently completing the task of moving the cover. In the process of moving the cover, the device uses a vacuum adsorption method to smoothly and accurately move the cover to the receiving frame fixed on the protective sheet. This design not only avoids the problem of cover deformation that may be caused by traditional clamping, but also greatly improves the safety and stability during transportation.

[0004] However, from a practical application perspective, the cap is typically circular in shape, which requires that the cap and the nozzle must be strictly coaxial when being attached to the battery. This ensures that the cap can be precisely aligned with the battery for placement. However, in actual production, due to constraints such as external environmental factors (such as vibration) and manufacturing precision (such as equipment precision and component processing errors), it is often difficult for the nozzle to ensure that the cap and the battery are precisely coaxial when attaching the cap. This problem directly leads to deviations between the cap and the battery after placement, which in turn affects the assembly precision and overall quality of the lithium battery, ultimately reducing the yield rate of the lithium battery. Summary of the Invention

[0005] The present invention proposes a power lithium battery cap loading device, which integrates the adsorption and fixing function and the four-corner clamping and centering function, and can effectively address and solve the problem mentioned in the above background technology that the adsorption nozzle is prone to position deviation during the cap transportation process.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a power lithium battery cap loading equipment, comprising: a clamping seat, a side of which is equipped with an exhaust pipe for sucking the inner cavity of the clamping seat; a suction cup is installed at the bottom, and the suction cup is connected to the inner cavity of the clamping seat; a central shaft is installed inside, and the central shaft has a synchronous gear; a synchronous gear arm is movably installed on the side of the clamping seat and meshes with the synchronous gear for transmission; a connecting seat is installed at the end of the synchronous gear arm, and the connecting seat is located on the outer side of the clamping seat, and an alignment push rod is installed on the connecting seat; a piston is fixedly installed on the outer side of the synchronous gear arm, and the piston is sealed with the clamping seat; when the exhaust pipe sucks the inner cavity of the clamping seat, the pressure in the inner cavity of the clamping seat is reduced, and the piston will therefore pull the alignment push rod synchronously toward the middle through the connecting seat until the alignment push rod reaches the bottom of the suction cup to adsorb and fix the battery cap, thereby realizing the coaxial arrangement of the battery cap and the clamping seat.

[0007] Furthermore, there are multiple alignment push rods, and the multiple alignment push rods are arranged in a ring with equal angles, and the center of the ring is on the central axis of the clamping seat.

[0008] Furthermore, a torsion spring is fixedly connected between the outer side of the central shaft and the inner side of the clamping seat.

[0009] Furthermore, a spot welding assembly is fixedly installed on the bottom of the clamping seat, an electrode head at the bottom of the spot welding assembly is located above the suction cup, and a detection spring is connected between the suction cup and the spot welding assembly.

[0010] Furthermore, a stop switch located above the suction cup is fixedly installed at the bottom of the spot welding assembly, and the entire machine stops working when the stop switch is pressed.

[0011] Furthermore, a synchronous disk is provided on the top of the clamping seat and is moved in a direction by a guide rod, and the top of the alignment push rod is movably installed with the synchronous disk by a guide frame, and a reset spring is connected between the top of the synchronous disk and the top of the guide rod.

[0012] Furthermore, a limited gear is fixedly installed on the top of the central shaft, and a connecting push rod is fixedly installed on the inner side of the synchronous disk. After the connecting push rod reaches the limited gear, the rotation of the central shaft is locked.

[0013] Furthermore, a detection tooth row is fixedly installed on the bottom outside the alignment push rod and is arranged toward the center line of the clamping seat. The tooth shape of the detection tooth row is an isosceles triangle.

[0014] Furthermore, the suction cup is installed on the bottom of the clamping seat using an oriented frame, and the bottom of the clamping seat is connected to the bottom of the oriented frame using a connecting pipe. When the suction cup descends to the bottom limit, the inner cavity of the suction cup is connected to the connecting pipe.

[0015] Furthermore, an air vent connected to the outside and a one-way air outlet valve installed on one side of the air vent are provided on the top of the directional frame. A reset turntable capable of sealing the air vent is fixedly installed at the bottom of the central axis, and a connecting hole is provided on the surface of the reset turntable.

[0016] The present invention has the following beneficial effects:

[0017] The present invention provides a power lithium battery cap loading device that first securely attaches the battery cap to the bottom of a suction cup. Simultaneously, alignment rods are installed on the four sides of a clamping base. These rods can move toward the central axis of the clamping base. During this movement, the sides of the rods contact the outer side of the battery cap, thereby precisely limiting its position.

[0018] As the alignment rods advance, the centerlines of the circle formed by the four alignment rods, the centerline of the battery cap, and the centerline of the clamping base are aligned. This alignment ensures that the clamping base remains precisely synchronized with the battery cap during subsequent movement, preventing any possible deviation or shaking.

[0019] Finally, based on the alignment of the clamping seat and the central axis of the battery cap, the equipment can stably and accurately move the battery cap to the end of the lithium battery and achieve precise assembly with the lithium battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] For example 1, please refer to Figure 1 and Figure 4 It can be seen that a rectangular mounting bracket is provided on the outside of the clamping seat 1, which can be used to fix it on the corresponding driving component, such as a robot. Figure 2 As shown, a suction pipe 12 is fixedly mounted on the side of the clamping base 1 and communicates with the inner cavity. The suction pipe 12 is generally connected to an external suction component, such as a vacuum pump. The vacuum pump is used to suction the inner cavity of the clamping base 1, thereby maintaining a relatively low pressure inside the clamping base 1, facilitating the subsequent suction and handling of the battery cap 8.

[0032] A suction cup 2 is installed at the bottom of the clamping seat 1. Figure 2 and Figure 6 It can be seen that the inner cavity of the suction cup 2 is connected to the inner cavity of the clamping seat 1. In the process of transporting the battery cap 8, the suction cup 2 is attached to the top of the battery cap 8 to absorb and transport the battery cap 8. Figure 2 、 Figure 4 and Figure 5It can be seen that the central shaft 4 is movably installed inside the clamping seat 1, and the synchronous gear 402 located in the inner cavity of the clamping seat 1 is fixedly installed on the outside of the central shaft 4. Correspondingly, the synchronous gear row arm 5 that meshes with the synchronous gear 402 is movably installed on the outside of the clamping seat 1. The end of the synchronous gear row arm 5 is fixedly installed on the outside of the clamping seat 1 with a connecting seat 6, and an alignment push rod 7 is installed on the connecting seat 6. Figure 1 and Figure 6 It can be clearly seen that there are four alignment push rods 7. The actual number of alignment push rods 7 can be adjusted as needed. Multiple alignment push rods 7 are placed on the outer side of the clamping seat 1, and the multiple alignment push rods 7 are arranged in a ring shape, with the center of the ring on the central axis of the clamping seat 1. Figure 5 As can be seen, a piston 501 is fixedly mounted on the outside of the synchronous gear arm 5, sealingly fitted to the clamping base 1. When the pressure within the clamping base 1 decreases, the piston 501 can drag the synchronous gear arm 5 toward the center of the clamping base 1. Under normal circumstances, due to the torsion spring 403 fixedly connected between the outer portion of the central shaft 4 and the inner side of the clamping base 1, the elastic force of the torsion spring 403 causes the synchronous gear arm 5 to extend relatively outward. At this time, the annular ring formed by the four alignment rods 7 has its largest diameter.

[0033] When the battery cap 8 needs to be moved, the vacuum pump uses the exhaust pipe 12 to suck the inside of the clamping seat 1, reducing the pressure in the inner cavity of the clamping seat 1. On the one hand, the battery cap 8 can be adsorbed by the suction cup 2; on the other hand, the reduced pressure in the inner cavity of the clamping seat 1 causes the piston 501 to drag the synchronous gear row arm 5 toward the middle of the clamping seat 1. Since the four synchronous gear row arms 5 are all engaged with the synchronous gear 402, the four synchronous gear row arms 5 on the outside of the clamping seat 1 will move closer to each other synchronously. Figure 1 and Figure 2 It can be seen that the battery cap 8 is circular in shape, and the bottom of the battery cap 8 is designed with an outer edge that can wrap the top of the lithium battery 9, ensuring that after the battery cap 8 and the lithium battery 9 are connected, the battery cap 8 can effectively protect the end of the lithium battery 9.

[0034] Since the four alignment push rods 7 are synchronously approaching the middle, they will eventually reach the outer side of the battery cap 8. Combined with the circular shape of the battery cap 8, the center of the ring formed by the multiple alignment push rods 7, the center of the battery cap 8, and the center of the clamping seat 1 are ultimately aligned in a straight line. The advantage of this design is that the coordinates of the central axis position of the clamping seat 1 can be easily determined. When the center lines of the battery cap 8 and the clamping seat 1 coincide, the battery cap 8 can be more easily attached to the lithium battery 9, thereby facilitating the subsequent connection between the battery cap 8 and the lithium battery 9.

[0035] On this basis, in order to further achieve effective connection between the battery cap 8 and the lithium battery 9, the present application adopts the spot welding method, but is not limited to other methods that can achieve connection between the two. Figure 2 and Figure 6 It can be seen that a spot welding assembly 10 is fixedly installed at the bottom of the clamping seat 1. The electrode head at the bottom of the spot welding assembly 10 is located above the suction cup 2. A detection spring 201 is connected between the suction cup 2 and the spot welding assembly 10. Under normal circumstances, the detection spring 201 pushes the suction cup 2 to move downward, forcing the suction cup 2 to be relatively far away from the bottom of the clamping seat 1. At the same time, the bottom surface of the suction cup 2 is also relatively far away from the electrode head on the spot welding assembly 10. When it is necessary to weld the connected battery cap 8 and lithium battery 9, the suction cup 2 is pushed downward by the clamping seat 1, and the lithium battery 9 on the battery cap 8 is further pressed against the end of the lithium battery 9. In this process, as the suction cup 2 and the clamping seat 1 are relatively close, the detection spring 201 is further pressed, and the connection strength between the battery cap 8 and the lithium battery 9 is further increased. When the electrode head on the spot welding assembly 10 reaches the top of the battery cap 8, in order to prevent the clamping seat 1 from excessively descending, combined with Figure 2 and Figure 6 It can be seen that a stop switch 11 located above the suction cup 2 is fixedly installed at the bottom of the spot welding assembly 10. When the electrode head on the spot welding assembly 10 extends from the suction cup 2, the suction cup 2 will hit the stop switch 11. The stop switch 11 generates an electrical signal and feeds back to the control system, thereby preventing the clamping seat 1 from excessively descending and causing the electrode head to be compressed and damaged.

[0036] Finally, after the battery cap 8 and the lithium battery 9 are welded together by the electrode head, the clamping seat 1 is removed from the lithium battery 9 by a robot arm, thereby completing the capping work of the lithium battery 9.

[0037] The second embodiment is a further improvement on the first embodiment. Figure 2 、 Figure 4 and Figure 5 As can be seen, a synchronization disk 3 is mounted on top of the clamping base 1, which moves up and down using a guide rod. The top of the alignment push rod 7 is movably mounted on the synchronization disk 3 using a guide frame. As the alignment push rod 7 follows the synchronization gear arm 5 in radial movement along the clamping base 1, the top of the alignment push rod 7 also moves along the synchronization disk 3. A return spring 300 is connected between the top of the synchronization disk 3 and the top of the guide rod. Under normal conditions, the elastic force of the return spring 300 forces the synchronization disk 3 downward to its bottom limit, ultimately causing the bottom of the synchronization disk 3 to rest against the top of the clamping base 1.

[0038] from Figure 2 and Figure 4It can be clearly seen that a limited gear 401 is fixedly installed on the top of the central shaft 4, and correspondingly, a connecting push rod 301 is fixedly installed on the inner side of the synchronous disk 3. When the synchronous disk 3 moves axially upward along the central shaft 4, the connecting push rod 301 can move to the tooth groove on the outer side of the limited gear 401. Since the synchronous disk 3 is restricted by the two guide rods and cannot rotate, when the connecting push rod 301 reaches the inside of the limited gear 401, it will also restrict the rotation of the limited gear 401 and the central shaft 4.

[0039] In actual application, the alignment push rod 7 can only move up and down along the connecting seat 6. Figure 2 、 Figure 4 and Figure 7 It can be seen that a detection tooth row 701 arranged toward the center line of the clamping seat 1 is fixedly installed on the outer bottom of the alignment push rod 7, and the tooth shape of the detection tooth row 701 is an isosceles triangle.

[0040] Under normal circumstances, the battery cap 8 is placed on the conveyor belt for transportation. When the battery cap 8 needs to be clamped, in order to prevent the extension of the alignment push rod 7 from causing the suction cup 2 to be difficult to adsorb the battery cap 8, the battery cap 8 is clamped. Figure 2 、 Figure 3 and Figure 5 It can be seen that the suction cup 2 is mounted on the bottom of the clamping seat 1 using an orientation frame. More specifically, the orientation frame is fixed to the top of the clamping seat 1, and the suction cup 2 can move at the bottom of the orientation frame. Figure 2 It can be seen that the top of the connecting pipe 13 is connected to the inner cavity of the clamping seat 1, and the outside passes through the bottom of the directional frame. Only when the suction cup 2 completely descends to the bottom, the inner cavity of the suction cup 2 will be connected to the connecting pipe 13. Figure 2 Similarly, when the sucker 2 moves upward, the side of the sucker 2 will block the connecting pipe 13. The top of the sucker 2 is located in the inner cavity of the directional frame. Figure 3 As can be seen, the top of the directional frame is provided with an air vent 200 connected to the outside, and a one-way air outlet valve 14 is installed on one side of the air vent 200. The one-way air outlet valve 14 allows the airflow in the directional frame's internal cavity to be discharged outward in a one-way manner. Correspondingly, a reset dial 15 capable of blocking the air vent 200 is fixedly mounted on the bottom of the central shaft 4, and a connecting hole 150 is opened on the surface of the reset dial 15. Under normal conditions, the central shaft 4 is restored to its normal state by the elastic force of the torsion spring 403. At this time, the alignment push rod 7 extends outward, connecting the connecting hole 150 with the air vent 200, forcing the outside and the internal cavity of the directional frame to communicate with each other.

[0041] When grabbing the battery cap 8 on the conveyor belt, the exhaust pipe 12 does not suck the inner cavity of the clamping seat 1 at this time. After the clamping seat 1 drives the suction cup 2 to move above the battery cap 8, the clamping seat 1 is controlled by the manipulator to move vertically downward. During this process, the alignment push rod 7 will first contact the conveyor belt. As the synchronous disk 3 continues to descend, the alignment push rod 7 pushes the synchronous disk 3 upward to compress the return spring 300 until the connecting push rod 301 moves to the outside of the limit gear 401, thereby restricting the movement of the central axis 4. When the suction cup 2 is attached to the battery cap 8 and further descends, the suction cup 2 presses on the detection spring 201, eventually reaching the stop switch 11, which stops the clamping seat 1 from descending. Afterwards, the inner cavity of the clamping seat 1 is sucked through the exhaust pipe 12. Since the central axis 4 is restricted and cannot rotate at this time, the alignment push rod 7 does not approach the center of the clamping seat 1 during the upward movement of the clamping seat 1.

[0042] As the clamping base 1 continues to ascend, when the suction cup 2 reaches the bottom, the connecting tube 13 connects with the inner cavity of the suction cup 2, allowing the suction cup 2 to absorb the battery cap 8. As the clamping base 1 further ascends, the battery cap 8 is positioned relatively above the detection gear row 701. Subsequently, when the connecting rod 301 disengages from the limit gear 401, the rotation restriction on the synchronization gear 402 is released. After the piston 501 drags the synchronization gear row arm 5 toward the center of the clamping base 1, the alignment push rod 7 is used to center and align the battery cap 8, ensuring that the centerline of the battery cap 8 coincides with the centerline of the clamping base 1.

[0043] After the battery cap 8 is moved to the top of the lithium battery 9 by the clamping seat 1, the clamping seat 1 drives the suction cup 2 and the alignment push rod 7 to move downward synchronously. During this process, the detection tooth row 701 at the bottom of the alignment push rod 7 moves downward and the detection tooth row 701 is used to position the lithium battery 9. If the battery cap 8 and the lithium battery 9 are not aligned, the alignment push rod 7 will hit the end of the lithium battery 9. As the clamping seat 1 descends, the alignment push rod 7 will push the synchronization disk 3 upward to compress the reset spring 300, and the connecting push rod 301 will be stuck in the limit gear 401 again. Not only that, as the clamping seat 1 descends further, the bottom of the battery cap 8 will hit the detection gear row 701. Since the connecting push rod 301 locks the limit gear 401 at this time, the alignment push rod 7 cannot extend outward, and as the clamping seat 1 continues to descend, the detection gear row 701 is used to limit the downward movement of the suction cup 2, and as the clamping seat 1 descends, the suction cup 2 approaches the stop switch 11 until the clamping seat 1 stops descending, to avoid excessive downward movement of the clamping seat 1 after the battery cap 8 and the lithium battery 9 are misaligned.

[0044] When the battery cap 8 and the lithium battery 9 are fully aligned, Figure 2As shown, as the clamping seat 1 moves further downward, the suction cup 2 will reach the stop switch 11, and then the electrode head on the spot welding assembly 10 will be used to weld the battery cap 8 and the lithium battery 9. During this process, when the suction cup 2 contacts the stop switch 11, the suction cup 2 moves upward relative to the directional frame, causing the airflow in the inner cavity of the directional frame to be quickly discharged from the one-way air outlet valve 14. Combined with the fact that the alignment push rod 7 moves closer to the middle of the clamping seat 1 at this time, the central axis 4 synchronously drives the reset turntable 15 to rotate, so that the air vent 200 is blocked. Therefore, the inner cavity of the directional frame is in a relatively sealed state at this time, and the suction cup 2 cannot move downward. After the battery cap 8 and the lithium battery 9 are welded, as the clamping seat 1 moves vertically upward, the suction cup 2 and the battery cap 8 are separated, and the bottom of the connecting pipe 13 is now blocked by the outside of the suction cup 2. The negative pressure inside the clamping seat 1 all acts on the piston 501, and the alignment push rod 7 is still kept close to the middle of the clamping seat 1. As the clamping seat 1 continues to move upward, the detection tooth row 701 will pass through the battery cap 8 and push the battery cap 8. If the battery cap 8 and the lithium battery 9 are firmly welded, the detection tooth row 701 will be affected by the tooth-shaped inclined surface and relatively away from the battery cap 8, and eventually detach from the battery cap 8; on the contrary, if the battery cap 8 and the lithium battery 9 are not firmly welded, the detection tooth row 701 will lift the battery cap 8 from the lithium battery 9.

[0045] Finally, when the detection tooth row 701 is separated from the lithium battery 9, the exhaust pipe 12 no longer sucks the inner cavity of the clamping seat 1, the inner cavity of the clamping seat 1 is equal to the external pressure, and the central axis 4 is restored to its original state by the torsion spring 403, and the entire device returns to the above-mentioned normal state.
