Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] Please refer to the following: Figures 1 to 3The automatic oiling system provided in this application embodiment will now be described. This automatic oiling system is used to coat the inner wall surface of a battery box 70. The battery box 70 has an open top. The automatic oiling system includes a frame 10, a carrier 11 mounted on the frame 10, a cotton swab clamping mechanism 20, an oil storage mechanism 30, a drive mechanism 50, and a robotic arm 40. The carrier 11 has at least one oiling station 110 for placing the battery box 70. Multiple oiling stations 110 can be arranged in a straight line on the carrier 11, with equal spacing between them. When the battery box 70 is placed in an oiling station 110, it is in a vertical position with its open end facing upwards. The robotic arm 40 can simultaneously coat the inner walls of multiple battery boxes 70.

[0037] The cotton swab clamping mechanism 20 clamps multiple cotton swabs 60, which can be arranged in a straight line at intervals. The oil-absorbing part 61 of the cotton swab 60, i.e., the end with oil-absorbing cotton wrapped around it, is at the bottom, while the upper end of the cotton swab 60 protrudes from the cotton swab clamping mechanism 20 for gripping by the robotic arm 40. The oil storage mechanism 30 is used to store oil. The oil storage mechanism 30 may be equipped with a liquid level sensor. When the liquid level sensor detects that the oil is about to run out, it can issue an alarm message, such as an audible and visual message, prompting the replenishment of oil to the oil storage mechanism 30.

[0038] The drive mechanism 50 can drive the carrier 11 to move back and forth between the oiling position and the unloading position of the frame 10. When the carrier 11 is in the oiling position, the robot arm 40 grabs the cotton swab 60 from the cotton swab clamping mechanism 20 and then moves it to the oil storage mechanism 30 to perform the oiling operation. After the oiling is completed, it moves to the oiling station 110 to perform the oiling operation on the inner wall of the battery box 70 placed in the oiling station 110. After the oiling operation is completed, the drive mechanism 50 drives the carrier 11 to move from the oiling position to the unloading position. At this time, the oiled battery box 70 can be taken out from the carrier 11 manually or by another robot arm 40 and placed in a predetermined area. Then the drive mechanism 50 drives the carrier 11 to move from the unloading position to the oiling position again, and so on.

[0039] The oiling process is automated, which greatly improves oiling efficiency and ensures uniformity and consistency, avoiding the low efficiency and poor quality problems caused by manual oiling. It avoids the risks of manual operation and reduces labor costs. The mechanized and automated operation can avoid the problem of poor product cleanliness and quality caused by impurities and bacteria that may be introduced by manual oiling. It can also adapt to large-scale production and meet the needs of fast and efficient production.

[0040] Compared with the prior art, the automatic oiling system provided in this application uses a robotic arm 40 to grasp a cotton swab 60 on a cotton swab clamping mechanism 20, and after the cotton swab is dipped in oil in an oil storage mechanism 30, it applies oil to the inner wall of the battery box 70 on the carrier 11. The robotic arm 40 can accurately grasp the cotton swab 60, so that the cotton swab 60 can stably pick up the oil and accurately apply the oil to a specific position inside the battery box 70, and the oil is applied evenly. The entire oiling process is automated, which improves oiling efficiency and accuracy, reduces errors and instability caused by manual operation, and at the same time reduces labor intensity and production costs, while improving product cleanliness and oiling effect.

[0041] See Figure 1 , Figure 2 The frame 10 has movable frames 14 slidably connected to both sides in the width direction, and the two ends of the carrier 11 are respectively connected and fixed to the movable frames 14 on the corresponding sides. The drive mechanism 50 is connected to the movable frames 14 to drive the movable frames 14 to move back and forth on the frame 10, thereby driving the carrier 11 to move between the oiling position and the unloading position. Specifically, the frame 10 includes a support 12 and four crossbars 13 arranged side by side, with two parallel crossbars 13 spaced at the top and bottom respectively. The movable frames 14 are slidably connected to the two crossbars 13 on the corresponding sides, so that the movable frames 14 can move back and forth along the crossbars 13.

[0042] The drive mechanism 50 includes a motor 51, a belt drive assembly 52, and at least two sliders 53. The output shaft of the motor 51 is connected to the belt drive assembly 52. ​​The at least two sliders 53 are slidably connected to the frame 10. The movable frame 14 is fixedly connected to the at least two sliders 53. When the sliders 53 are driven by the belt drive assembly 52 and slide, they can drive the movable frame 14 to move on the frame 10, thereby driving the carrier 11 to move. Each crossbar 13 is slidably mounted with a slider 53. The sliders 53 are fixedly connected to the movable frame 14 on the corresponding side. The motor 51 drives each slider 53 to slide relative to the crossbar 13 through the transmission assembly, thereby driving the movable frames 14 on both sides to move linearly relative to the frame 10. The carrier 11 moves back and forth relative to the frame 10 with the movable frame 14 to achieve back and forth movement between the oiling position and the unloading position.

[0043] Specifically, the drive mechanism 50 includes two motors 51, one of which is fixed near the bottom of the bracket 12, and the other is fixed near the top of the bracket 12. The belt drive assembly 52 includes two belt drive mechanisms 520, each of which includes a shaft 521, a drive pulley 522, a first driven pulley 523, a second driven pulley 524, a first belt 525, and a second belt 526. Taking the belt drive mechanism 520 located near the lower end of the frame 10 as an example, a shaft 521 is rotatably mounted between the two ends of the two crossbars 13 at the bottom. A first driven pulley 523 and two second driven pulleys 524 are sleeved on the shaft 521. The two second driven pulleys 524 are located at the two ends of the shaft 521, and the first driven pulley 523 is located between the two second driven pulleys 524. The output shaft of the motor 51 is connected to the drive pulley 522, and the drive pulley 522 and the first driven pulley 523 are connected by a first belt 526. The transmission connection is as follows: a second belt 526 connects the two second driven pulleys 524 at both ends of the frame 10. Thus, the motor 51 drives the rotating shaft 521 to rotate via the first belt 525 and the first driven pulley 523. The rotating shaft 521 rotates via the second driven pulleys 524 at both ends, which in turn drives the second belt 526 to rotate. The second belt 526 drives the corresponding two sliders 53 to move on the crossbar 13, thereby moving the movable frame 14. The carrier 11 moves between the oiling position and the unloading position along with the movable frame 14. Alternatively, a single motor 51 can drive a belt drive assembly 52 to drive the movable frame 14, thus achieving the movement of the carrier 11 between the oiling position and the unloading position.

[0044] Please see Figures 1 to 4 The oil storage mechanism 30 is fixed to the top of the movable frame 14. The oil storage mechanism 30 moves with the movable frame 14, meaning that the oil storage mechanism 30 and the carrier 11 move synchronously between the oiling position and the unloading position. The oil storage mechanism 30 includes an oil storage box 31, an oil wiping plate 32, and a fixing plate 33. The oil storage box 31 is fixed to the top of the movable frame 14, and its length is parallel to the length of the frame 10. The fixing plate 33 is fixed to the side of the oil storage box 31 away from the carrier 11. The oil wiping plate 32 is connected and fixed above the fixing plate 33 and is horizontally suspended above the oil storage box 31. The side of the oil wiping plate 32 away from the fixing plate 33 has an oil wiping groove 320 for squeezing out excess oil absorbed by the oil-soaked part 61 of the cotton swab 60.

[0045] In other words, the oil wiping groove 320 is located above the oil storage box 31. After the robotic arm 40 picks up the cotton swab 60 and finishes applying oil in the oil storage box 31, it moves the cotton swab 60 to the position of the oil wiping groove 320 and then lifts the cotton swab 60 upward to a certain height. When the oil-soaked part 61 at the end of the cotton swab 60 slides out of the oil wiping groove 320, the excess oil on the oil-soaked part 61 is squeezed off and falls into the oil storage box 31. This completes the oil wiping operation. The squeezed-off oil returns to the oil storage box 31. On the one hand, this ensures that the amount of oil on the cotton swab 60 is just right and there is no dripping. This avoids excess oil dripping onto other parts and causing equipment contamination. On the other hand, it saves oil. Understandably, the oil storage box 31 can also be detachably mounted on the movable frame 14, so that when the oil is exhausted, the oil storage box 31 can be taken out and the oil can be replenished; when the robotic arm 40 grabs multiple cotton swabs 60 at a time, the oil wiping grooves 320 on the oil wiping plate 32 are also set at intervals of a corresponding number, so that the oil wiping operation can be performed on each cotton swab 60 at the same time.

[0046] See Figure 1 , Figures 3 to 5 The oil wiping tank 320 includes an inlet section 321, a transition section 322, and an oil squeezing section 323 connected in sequence. The inlet section 321 has a gradually widening opening, which facilitates the robot arm 40 to grasp the cotton swab 60 and move it into the oil wiping tank 320 from the inlet section 321. The transition section 322 is a constant diameter section with a fixed width. The oil squeezing section 323 is arc-shaped, and its diameter is smaller than the maximum diameter of the oil-soaked part 61 of the cotton swab 60. Thus, after the cotton swab 60 enters the oil squeezing section 323, when the robot arm 40 lifts the cotton swab 60 upward to a predetermined height and removes it from the oil squeezing section 323, the oil squeezing section 323 can squeeze out the excess oil adsorbed by the oil-soaked part 61, and the squeezed-out oil falls into the oil storage box 31.

[0047] See Figure 6 and Figure 7 The cotton swab clamping mechanism 20 includes a base 21, two clamping plates 22, and a power source 23. The base 21 is fixed to the frame 10 by a fixing block, and the length direction of the base 21 is parallel to the width direction of the frame 10. The power source 23 is fixed to the base 21, and the two clamping plates 22 are located on the top surface of the base 21 and can move relative to each other. The power source 23 is used to drive the two clamping plates 22 to clamp or release the cotton swab 60, that is, the power source 23 drives the two clamping plates 22 to move in opposite directions to complete the clamping and releasing operation of the cotton swab 60. The top surface of the base 21 is provided with a plurality of blind holes 210 at intervals, which are used for the insertion of the oil-soaked part 61 of the cotton swab 60.

[0048] See Figure 1 , Figure 6 and Figure 7Specifically, the power source 23 includes two cylinders. Stepped surfaces for fixing the cylinders are provided at both ends of the base 21 along its length. The top surface of the cylinder is basically flush with the top surface of the base 21. Two sliders 53 are provided on the cylinders, and each slider 53 is connected and fixed to the clamping plate 22 by screws. In this way, the cylinders at both ends synchronously drive the two clamping plates 22 to move, thereby enabling the clamping and releasing operation of the cotton swab 60. A locking tooth 220 is provided on the opposite side of each of the two clamping plates 22. The two locking teeth 220 on the two clamping plates 22 are used to hold the cotton swab 60 in an upright position when clamped by the two clamping plates 22. The base 21 has multiple blind holes 210 spaced in a straight line, allowing the cotton swab clamping mechanism 20 to hold and clamp a row of cotton swabs 60. After the robotic arm 40 has picked up a portion of the cotton swabs 60 from the clamping mechanism 20 and completed the oiling operation on the inner wall of the battery box 70, the cotton swabs 60 are returned to the clamping mechanism 20. The robotic arm 40 then picks up another portion of the cotton swabs 60, and so on, until all the cotton swabs 60 have been used, and then the cycle repeats. After a period of use, all the cotton swabs 60 on the clamping mechanism 20 can be removed and replaced with several new cotton swabs.

[0049] Please see Figure 1 , Figure 8 A robotic arm 40 is positioned beside the frame 10. At its end, the robotic arm 40 has a lifting mechanism 41, a mounting plate 42, a drive source 43, and multiple grippers 44. The mounting plate 42 is connected to the bottom of the lifting mechanism 41, and the drive source 43 is fixed to the mounting plate 42. The drive source 43 can be, but is not limited to, a cylinder. The multiple grippers 44 are connected to the drive source 43, which synchronously drives each gripper 44 to open and close, thus gripping multiple cotton swabs 60. The lifting mechanism 41 drives the mounting plate 42 to rise and fall vertically, thereby raising and lowering each gripper 44 and the gripped cotton swabs 60. After the robotic arm 40 grips the cotton swabs 60 and completes the oiling operation, it moves the cotton swabs 60 into the oil wiping groove 320. At this time, the lifting mechanism 41 moves the mounting plate 42 upward, allowing the grippers 44 to raise the cotton swabs 60 to a predetermined height and complete the oiling operation. Figure 8 As shown, there are two grippers 44, which are symmetrically installed on opposite sides of the mounting plate 42. The drive source 43 uses two cylinders, that is, the two cylinders synchronously drive the grippers 44 on both sides to grasp and release the cotton swab 60.

[0050] Compared to manual oiling, mechanized carrier transport of battery boxes, in conjunction with robotic arms, offers numerous significant advantages in completing a series of operations. Firstly, the stable operation of the carrier on the assembly line ensures the stability of the battery boxes during transport, greatly reducing the risk of displacement or damage due to vibration and other factors. Manual handling struggles to maintain such stability consistently. Secondly, the robotic arms move precisely and quickly, accurately moving to designated positions within a short time. Whether picking up cotton swabs, placing them in the oil storage box, or applying oil to the inner wall of the battery box, their efficiency far surpasses manual operation. Furthermore, the consistent force and height at which the robotic arms grip the cotton swabs ensure standardized operation, resulting in more even oil adhesion to the swabs and application to the inner wall of the battery box. This effectively improves product quality and avoids problems such as unstable gripping and uneven oil application that can occur with manual operation. From a cost perspective, the robotic arms can work continuously, significantly reducing labor costs. Moreover, the highly standardized operation reduces product scrap rates due to human error, further saving production costs. In addition, using robotic arms for oiling operations improves safety, avoids human contact with potentially hazardous substances such as oil, reduces occupational health risks, and prevents accidents caused by human negligence when working under a preset program.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
