Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a cleaning device for a battery cell liquid injection port. Background Art

[0002] In the complex and delicate process of battery cell manufacturing, the cleaning of the liquid filling port plays a vital role. The liquid filling port is the key part for injecting electrolyte into the battery cell, and its cleanliness is directly related to the safety and overall performance of the battery. If there is electrolyte remaining in the liquid filling port, it will cause a series of serious problems in the subsequent sealing nail welding step. Since the electrolyte has a certain chemical activity, the residual electrolyte may react violently in the high temperature environment of welding, thereby producing an explosion point, which will not only destroy the structural integrity of the battery, but also may cause dangerous situations such as battery short circuit. Moreover, the phenomenon of explosive welding is also very easy to occur, making it impossible for the sealing nail to be effectively sealed, and the sealing of the battery is destroyed, which in turn seriously affects the battery quality rate, making a large number of batteries unable to meet the qualified standards, resulting in increased production costs and waste of resources. At the same time, it also brings great safety hazards to the use of batteries, affecting the battery quality and safety.

[0003] At present, the most common method of cleaning the liquid injection port in battery cell production is to manually use a wiping material dipped in a detergent to clean the liquid injection port. The staff will use specific wiping materials, such as clean non-woven fabrics or dust-free cloths, dipped in specially formulated detergents, and carefully wipe the liquid injection port. Although this method can meet the cleaning needs to a certain extent, it also has some limitations. For example, the efficiency of manual cleaning is relatively low, and it is difficult to adapt to large-scale and high-efficiency production requirements; moreover, the consistency and stability of manual operation are difficult to guarantee, and the operating techniques and strength of different workers may vary, which may lead to uneven cleaning effects, thereby causing certain fluctuations in battery quality. Moreover, long-term repetitive cleaning work can easily make the operator feel tired. Once the operator is tired, not only will the cleaning efficiency be further reduced, but it may also lead to a decrease in cleaning concentration, so that it cannot be guaranteed that each liquid injection port can be cleaned with high quality.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 13 , the present invention provides a technical solution.

[0033] A battery cell injection port cleaning device, comprising a mechanical arm 1, a feed rack 23 and a device rack 47, wherein a positioning device is installed on the surface of the feed rack 23 for positioning and fixing the battery cell 4, a support plate 34 and a cloth puller 9 are installed on the device rack 47, a cloth unwinding assembly is installed on the support plate 34, the cloth puller 9 is used to pull out cloth from the cloth unwinding assembly, a cloth cutter 7 is installed on the device rack 47, the cloth cutter 7 is used to clamp and cut the cloth, a liquid spray controller 12, a pressure barrel 10, a liquid spray valve 5, and a detergent tank 6 are installed on the device rack 47, and the liquid spray controller 12 controls the pressure barrel 10 to make the detergent tank 6 The detergent flows into the detergent trough 6 through the spray valve 5. A rotator 2 is installed at the end of the robot arm 1, and a wiping assembly is installed at the lower end of the rotator 2. The robot arm 1 is used to drive the wiping assembly to move the wiping liquid injection port. A cloth recovery box 11 is installed on the device frame 47. The wiping assembly grabs the cloth at the cloth grabbing position, and then moves the assembly to make the cloth dipped in the detergent, and finally moves to the battery cell 4 scrubbing position. The rotator 2 drives the wiping assembly to rotate and clean the battery cell 4 injection port, and moves to the cloth recovery position after scrubbing is completed, and releases the wiping assembly to allow the used scrubbing cloth to fall into the cloth recovery box 11 for recovery.

[0034] Please refer to Figure 1 In the production process of the battery cell 4, the positioning device positions and fixes the battery cell 4 to ensure the accuracy of the subsequent cleaning operation. At the same time, the cloth puller 9 pulls the cloth from the cloth unwinding assembly to prepare for the cutting work. The cloth cutter 7 clamps the cloth and cuts it, waiting for the next step. The spray controller 12 controls the pressure barrel 10, so that the detergent flows smoothly from the barrel to the spray valve 5, and then flows from the spray valve 5 into the detergent trough 6 to provide cleaning liquid supply for the scrubbing work. The robot arm 1 flexibly drives the rotator 2 to move quickly to the cloth grabbing position to wipe. The component grabs the cloth and dips it in the detergent, and then moves to the scrubbing position of the liquid injection port of the battery cell 4. At this time, the rotator 2 drives the wiping component to rotate, thereby driving the cloth dipped in the detergent to rotate, and cleaning the liquid injection port of the battery cell 4 to ensure the cleanliness of the liquid injection port. After the scrubbing task is completed, the robot arm 1 drives the rotator 2 to move to the cloth recovery position again, so that the wiping component releases the clamping of the cloth, and the used scrubbing cloth naturally falls into the cloth recovery box 11. At this point, the entire cleaning process of the liquid injection port of the battery cell 4 is completed, laying a solid foundation for the high-quality production of the battery cell 4.

[0035] By building a collaboratively operated device that covers every link from material preparation, cleaning operations to waste recycling, each link is closely connected and operates in an orderly manner, thus helping to realize the automated operation process of the entire production line, comprehensively improving the overall production management refinement and production efficiency, and ensuring that production activities can be carried out stably, efficiently and continuously, meeting the requirements of modern industrial production for high-quality and high-efficiency output.

[0036] Please refer to Figures 2 to 4 The wiping assembly includes a connecting head 13 and two clamping arms 16. The two clamping arms 16 are symmetrically arranged on the two side surfaces of the connecting head 13. The two clamping arms 16 can move horizontally. The clamping operation of the cloth is realized by the relative displacement of the two clamping arms 16. Two symmetrically arranged first electric push rods 15 are installed inside the connecting head 13. The two first electric push rods 15 respectively drive the two clamping arms 16 to move horizontally. A rubber head 17 is installed at the bottom end of the connecting head 13. The rubber head 17 is located between the two clamping arms 16. The clamping arm 16 is installed. In the process of clamping the cloth with the wiping component, the wiping component is moved first, and the rubber head 17 is moved downward and pressed on the cloth, causing the cut cloth to be concave to form a U shape. Then, the two clamping arms 16 clamp the two sides of the U-shaped cloth to make it fit tightly on the surface of the rubber head 17. By setting the rubber head 17, it presses against the cloth when wiping, effectively avoiding the situation where the surface of the battery cell 4 is scratched due to the clamping arm 16 directly clamping the cloth for wiping. Conventionally, the cloth cutter 7 has a space for the cloth to be concave.

[0037] Furthermore, the lower end of the rubber head 17 is movably connected to a connecting rod 19 that can move up and down, a first spring 18 is fixedly connected between the connecting rod 19 and the rubber head 17, a ball head 20 is fixedly connected to the lower end of the connecting rod 19, and a rubber pad 21 is movably connected to the surface of the ball head 20, so that the rubber pad 21 can be universally rotated with the ball head 20 as the axis, and a plurality of second springs 22 arranged in a ring array are fixedly connected between the rubber pad 21 and the rubber head 17. By setting up in this way, the existence of the first spring 18 enables the rubber head 17 to compress the spring by moving the connecting rod 19 up and down when it is subjected to an impact force in the vertical direction. Thereby, the impact force is effectively buffered, and the device is prevented from being damaged due to rigid collision, thus providing good protection for the entire device. For example, when contacting uneven parts such as protrusions during wiping, the first spring 18 can provide buffering to avoid rigid collision. The setting of the rubber pad 21 and the second spring 22 also has the same effect. The rubber pad 21 is designed to rotate in a universal direction with the ball head 20 as the axis, which greatly enhances the adaptability when contacting the protrusion. The second springs 22 arranged in a plurality of annular arrays provide multi-point elastic support between the rubber pad 21 and the rubber head 17, so that the rubber pad 21 can provide buffering after rotation and can automatically reset.

[0038] Please refer to Figures 5 and 6There are two groups of positioning devices, which are symmetrically installed on both sides of the feeding rack 23. The positioning devices include a positioning head 3, a connecting plate 24, a protective shell 25 and a rubber pressing block 33. The connecting plate 24 is installed on the surface of the feeding rack 23, and the protective shell 25 is installed on the top of the connecting plate 24. The protective shell 25 and the positioning head 3 are movably connected. The protective shell 25 is used to drive the positioning head 3 to move horizontally. The positioning head 3 has a U-shaped clamping recess. The rubber pressing block 33 is installed at the center of the wall surface of the U-shaped clamping recess on the positioning head 3. Conventionally, the positioning head 3 has a plurality of U-shaped clamping recesses, and each U-shaped clamping recess is correspondingly provided with a rubber pressing block 33. Figures 5 and 6 The positioning head 3 shown in the figure has two U-shaped clamping recesses. By starting the protective shells 25 of the two positioning device bells, the two positioning heads 3 are driven to move toward each other, so that the battery cell 4 is placed in the two U-shaped clamping recesses, and then the two rubber pressing blocks 33 are pressed against the battery cell 4 to position and clamp it.

[0039] A horizontally movable U-shaped auxiliary pressing block 32 is installed on the surface of the protective shell 25. The U-shaped auxiliary pressing block 32 movably penetrates the surface of the positioning head 3. The rubber pressing block 33 is located on the inner side of the U-shaped auxiliary pressing block 32. The surfaces opposite to the ends of the U-shaped auxiliary pressing block 32 are inclined slopes. By setting the U-shaped auxiliary pressing block 32, after the two rubber pressing blocks 33 press against the battery cell 4 to position and clamp it, the U-shaped auxiliary pressing block 32 continues to move horizontally, and the two ends of the U-shaped auxiliary pressing block 32 are respectively moved to the left and right sides of the battery cell 4 until the inclined surface of the U-shaped auxiliary pressing block 32 presses against the surface of the battery cell 4, further limiting the battery cell 4, that is, the rubber pressing blocks 33 on the two opposite positioning devices press against the front and back of the battery cell 4, and the U-shaped auxiliary pressing blocks 32 on the positioning device press against the left and right sides of the battery cell 4.

[0040] Furthermore, a second electric push rod 26 is installed inside the protective shell 25, and a push plate 27 is fixedly connected to the telescopic end of the second electric push rod 26. A pressure plate 29 is fixedly installed on the surface of the positioning head 3, and a third spring 28 is fixedly connected between the pressure plate 29 and the push plate 27. The surface of the pressure plate 29 is fixedly connected to a limiting guide rod 30, and the push plate 27 is provided with a through hole for the limiting guide rod 30 to pass through. The surface of the push plate 27 is fixedly connected to the limiting guide rod 30, and the limiting guide rod 30 is fixedly connected to the U-shaped auxiliary pressure block 32. The protective shell 25 has space for the push plate 27, the linkage rod 31, and the limiting guide rod 30 to move. By starting the second electric push plate The rod 26 extends and retracts, driving the push plate 27 to move. The movement of the push plate 27 drives the third spring 28, the pressure plate 29, the positioning head 3, the linkage rod 31, and the U-shaped auxiliary pressing block 32 to move together until the rubber pressing block 33 presses against the surface of the battery cell 4. At this time, the positioning head 3 and the pressure plate 29 cannot move. The second electric push rod 26 continues to extend, driving the push plate 27, the linkage rod 31, and the U-shaped auxiliary pressing block 32 to move. While compressing the third spring 28, the U-shaped auxiliary pressing block 32 continues to move until the U-shaped auxiliary pressing block 32 presses against the surface of the battery cell 4, thereby realizing a power source to complete the rubber pressing block 33 and the U-shaped auxiliary pressing block 32 pressing against the surface of the battery cell 4.

[0041] Please refer to Figures 7 to 10 The cloth unwinding assembly includes a winding roller 8, a rotating shaft 36 and a fixed disk 42. The fixed disk 42 and the support plate 34 are fixedly connected, and the rotating shaft 36 and the fixed disk 42 are movably connected. The winding roller 8 is movably sleeved on the surface of the rotating shaft 36, and a fixing block 35 for fixing the winding roller 8 is installed on the surface of the winding roller 8. When the winding roller 8 is sleeved on the rotating shaft 36, the fixing block 35 fixes the winding roller 8 and the rotating shaft 36, so that the winding roller 8 and the rotating shaft 36 rotate together when unwinding. For example, the fixing block 35 is passed through the winding roller 8 and is threadedly connected to the rotating shaft 36, so that the winding roller 8 and the rotating shaft 36 are fixedly connected together.

[0042] A horizontally movable balancing slide 37 is installed on the back of the fixed disk 42. The rotating shaft 36 movably passes through the fixed disk 42 and is rotatably connected to the balancing slide 37. The surface of the fixed disk 42 is provided with an avoidance groove 40 for the horizontal movement of the rotating shaft 36. The surface of the fixed disk 42 is rotatably connected with a guide roller 41. The guide roller 41 plays the role of guiding the material discharge path. The material is unfolded around the guide roller 41 during discharge, and the position of the guide roller 41 corresponds to the maximum diameter position of the fabric roll when it is installed, so as to ensure that the complete fabric roll can be installed smoothly.

[0043] Since a horizontally movable balancing slide 37 is provided, it can drive the rotating shaft 36, the winding roller 8 and the cloth roll placed on the winding roller 8 to move together in the horizontal direction. During the unwinding process of the cloth roll, its diameter will gradually decrease. If the position of the unwinding roll remains fixed, the angle of the cloth will change when it passes through the guide roller 41, which will cause the cloth tension to change, and finally affect the cloth quality.

[0044] The horizontal movement of the balance slide 37 drives the cloth roll to move horizontally, so that the cloth roll can always be kept in a relatively stable position, ensuring that the angle of the cloth remains basically unchanged during the process from unwinding to passing through the guide path of the guide roller 41, thereby maintaining the stability of the cloth tension. In this way, whether in the initial stage of cloth unwinding or in the process of continuous unwinding of the cloth and gradual reduction in diameter, stable quality cloth can be provided for subsequent processing steps.

[0045] Furthermore, a T-shaped slider 38 is fixedly connected to the surface of the balancing slide 37, and a T-shaped slide groove 39 is provided on the back of the fixed plate 42 for horizontal movement of the T-shaped slider 38. A support block 43 is fixedly connected to the back of the fixed plate 42, and a guide slide bar 44 is fixedly connected to the surface of the support block 43. A balancing slider 45 is fixedly connected to the surface of the balancing slide 37, and the support block 43 movably penetrates the surface of the balancing slider 45. A fourth spring 46 is fixedly connected between the balancing slider 45 and the support block 43. When the complete cloth roll is placed in place, the fourth spring 46 is elastically deformed, thereby storing a certain amount of elastic potential energy. As the cloth is continuously released, the diameter of the cloth roll gradually decreases. At this time, the elastic potential energy stored in the fourth spring 46 in the early stage begins to be released, generating a reverse force, driving the balancing slider 45 connected thereto to be displaced, thereby pushing the balancing slide 37 to move as a whole. This movement effect enables the cloth roll to continuously maintain contact with the guide roller 41, which is beneficial for the balancing slide 37 to automatically move when the radius of the cloth roll becomes smaller.

[0046] Please refer to Figures 11 to 13, an auxiliary recovery base 49 which can be moved horizontally is installed on the device frame 47, and a third electric push rod 48 is installed on the device frame 47. The third electric push rod 48 is used to drive the auxiliary recovery base 49 to move horizontally, and a rotatable auxiliary pressing plate 53 is installed at the lower end of the auxiliary recovery base 49, and the auxiliary pressing plate 53 is located above the cloth recovery box 11. A recovery funnel 57 is installed on the device frame 47, and the robot arm 1 drives the used scrubbing cloth to fall into the recovery funnel 57, and then drives the auxiliary recovery base 49 to move horizontally to drive the auxiliary pressing plate 53 to move to the lower end of the recovery funnel 57 to catch the scrubbing cloth that has slipped, and then tilts the auxiliary pressing plate 53 to make the scrubbing cloth fall into the cloth recovery box 11, and changes the position of the auxiliary pressing plate 53 by moving the auxiliary recovery base 49, so that the scrubbing cloth falls from different positions, avoids falling at a single position, and makes the scrubbing cloth accumulate at a fixed position in the cloth recovery box 11, causing space waste.

[0047] A fourth electric push rod 55 is installed at the lower end of the auxiliary recovery base 49, and the telescopic end of the fourth electric push rod 55 is rotatably connected to the auxiliary pressing plate 53. The telescopic end of the fourth electric push rod 55 is fixedly connected to the second motor 56, and the output end of the second motor 56 is fixedly connected to the auxiliary pressing plate 53. A leakage plate 14 is installed on the inner wall of the cloth recovery box 11. The auxiliary pressing plate 53 is driven to rotate by starting the second motor 56, and the auxiliary pressing plate 53 is driven to move up and down by starting the fourth electric push rod 55. When the used scrubbing cloth falls into the cloth recovery box 11, it falls on the leakage plate 14. The auxiliary pressing plate 53 moves up and down to squeeze the used scrubbing cloth in the cloth recovery box 11, so that the water in the cloth is squeezed out, and the squeezed water passes through the leakage plate 14 and flows to the bottom of the cloth recovery box 11. Conventionally, the bottom of the cloth recovery box 11 has an opening for draining liquid, so as to perform preliminary dry and wet separation to prevent the water in the cloth recovery box 11 from accumulating more and more.

[0048] Furthermore, a first motor 50 is installed on the surface of the auxiliary recovery base 49, and a threaded rod 51 is coaxially fixedly connected to the output end of the first motor 50. The threaded rod 51 and the auxiliary recovery base 49 are rotatably connected. A transmission rod 52 is threadedly sleeved on the surface of the threaded rod 51, and support rods 54 are rotatably connected at both ends of the transmission rod 52. One end of the support rod 54 and the auxiliary pressure plate 53 are rotatably connected. By arranging the threaded rod 51, the transmission rod 52 and the support rod 54, the pressure borne by the fourth electric push rod 55 and the second motor 56 can be shared. When the second motor 56 is started to drive the auxiliary pressure plate 53 to rotate, the first motor 50 is started at the same time to drive the threaded rod 51 to rotate. The rotation of the threaded rod 51 drives the transmission rod 52 to move horizontally along the surface of the threaded rod 51, thereby causing the angle of the support rod 54 to change, so that the support rod 54 can cooperate with the rotation of the auxiliary pressure plate 53 to perform an adaptive rotation action. Similarly, when the fourth electric push rod 55 is started to drive the auxiliary pressing plate 53 to move downward, the rotating support rod 54 can also work together to enable the auxiliary pressing plate 53 to complete the downward movement operation smoothly.

[0049] This scheme is specifically as follows: positioning of battery cell 4 and preparation of fabric: when transporting battery cell 4 to the working area of ​​the positioning device on the surface of feeding rack 23, two sets of positioning devices are started, specifically, the second electric push rod 26 starts to extend, driving the push plate 27 to move, and the push plate 27 then drives the third spring 28, the pressure plate 29, the positioning head 3, the linkage rod 31, and the U-shaped auxiliary pressing block 32 to move together. When the rubber pressing block 33 is tightly pressed against the battery cell 4, the positioning head 3 and the pressure plate 29 stop moving, and the second electric push rod 26 continues to extend, driving the push plate 27, the linkage rod 31, and the U-shaped auxiliary pressing block 32 to move, compressing the third spring 28 while making the inclined surfaces at both ends of the U-shaped auxiliary pressing block 32 press against the left and right surfaces of the battery cell 4, further accurately limiting the battery cell 4, ensuring its stable position in subsequent cleaning operations, and providing accurate positioning of the operation object for cleaning work;

[0050] At the cloth unwinding assembly on the support plate 34, the winding roller 8 with the cloth roll installed is mounted on the rotating shaft 36, and the winding roller 8 and the rotating shaft 36 are fixed using the fixing block 35 so that they can rotate together during unwinding. At this time, the cloth roll is placed in place, causing the fourth spring 46 to undergo elastic deformation, storing a certain amount of elastic potential energy, and preparing for subsequent automatic adjustment.

[0051] Fabric cutting and cleaning preparation: the fabric puller 9 pulls the fabric from the fabric unwinding assembly, the fabric cutter 7 clamps the fabric and cuts it, and the cut fabric is ready to enter the cleaning process;

[0052] The liquid spraying controller 12 controls the pressure barrel 10, so that the cleaning agent flows smoothly from the barrel through the liquid spraying valve 5 into the cleaning agent trough 6, so as to prepare the cleaning liquid supply for the scrubbing work and ensure that the cleaning work can proceed smoothly.

[0053] Grab the cloth and dip it in detergent: The robot arm 1 drives the rotator 2 to quickly move to the cloth grabbing position, and drives the rubber head 17 in the wiping assembly to move downward and press on the cloth, so that the cut cloth is concave to form a U shape. Then, the two clamping arms 16 move horizontally under the drive of the first electric push rod 15, clamp the two sides of the U-shaped cloth, so that it fits tightly on the surface of the rubber head 17, and completes the cloth grabbing operation;

[0054] After grabbing the cloth, the robot arm 1 is moved to make the cloth dip into the detergent, ensuring that the cloth on the wiping component is fully soaked in the detergent to provide sufficient cleaning ability for subsequent cleaning work.

[0055] Cleaning the liquid injection port of the battery cell 4: the robot arm 1 drives the wiping component dipped in the detergent to move to the wiping position of the liquid injection port of the battery cell 4. At this time, the rotator 2 drives the wiping component to rotate, thereby driving the cloth dipped in the detergent to rotate, and performing a full-scale cleaning operation on the liquid injection port of the battery cell 4. During the wiping process, if the wiping component contacts the bumps and other uneven parts on the surface of the battery cell 4, the first spring 18, the rubber pad 21 and the second spring 22 can play a buffering role. The first spring 18 compresses the spring through the up and down movement of the connecting rod 19 to buffer the impact force in the vertical direction and prevent the device from being damaged by rigid collision; the rubber pad 21 rotates universally with the ball head 20 as the axis to enhance the adaptability when contacting the bumps; the second springs 22 arranged in a plurality of ring arrays provide multi-point elastic support, so that the rubber pad 21 can buffer and automatically reset after rotation, ensuring the stability and safety of the cleaning process, while also protecting the surface of the battery cell 4 from being scratched.

[0056] Recycling of used scrubbing cloth: After the scrubbing task is completed, the robot arm 1 drives the rotator 2 to move to the opening of the recovery funnel 57, so that the wiping component releases the clamping of the cloth, and the used scrubbing cloth naturally falls into the recovery funnel 57, and then the third electric push rod 48 drives the auxiliary recovery base 49 to move horizontally, so that the auxiliary pressing plate 53 at the lower end of the auxiliary recovery base 49 moves to the lower end of the recovery funnel 57 to catch the sliding scrubbing cloth, and then the second motor 56 is started, and the second motor 56 drives the auxiliary pressing plate 53 to rotate, so that the auxiliary pressing plate 53 is tilted, so that the scrubbing cloth falls onto the leakage plate 14 in the cloth recovery box 11, and the position of the auxiliary pressing plate 53 is changed by moving the auxiliary recovery base 49, so that the scrubbing cloth falls from different positions, avoiding accumulation at a fixed position in the cloth recovery box 11, causing space waste, and realizing effective recovery and sorting of used cloth, which provides convenience for subsequent processing;

[0057] By starting the fourth electric push rod 55, the fourth electric push rod 55 drives the horizontal auxiliary pressing plate 53 to move downward, and the auxiliary pressing plate 53 moves downward to squeeze the used scrubbing cloth on the leakage plate 14, so that the water in the cloth is squeezed out, and the squeezed water passes through the leakage plate 14 and flows to the bottom of the cloth recovery box 11, and the liquid discharge opening at the bottom of the cloth recovery box 11 discharges the water to perform preliminary dry and wet separation.

[0058] During the process that the second motor 56 drives the auxiliary pressure plate 53 to rotate and the fourth electric push rod 55 drives the auxiliary pressure plate 53 to move up and down, the first motor 50 starts to drive the threaded rod 51 to rotate, and the rotation of the threaded rod 51 drives the transmission rod 52 to move horizontally along its surface, causing the angle of the support rod 54 to change, so that the support rod 54 can cooperate with the rotation and up and down movement of the auxiliary pressure plate 53 to perform adaptive movements, share the pressure borne by the fourth electric push rod 55 and the second motor 56, ensure the stable operation of the entire recovery device, and improve the reliability and durability of the device.
