[0034] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.
[0035] Prismatic batteries are a type of lithium-ion battery packaging. They feature a rectangular metal (usually aluminum or steel) casing with an electrolyte injection port. During the initial manufacturing stages of lithium-ion batteries, electrolyte is injected into the battery through the port at the end of the assembly process. This utility model is used to clean the injection port.
[0036] Reference Figure 1-3, a clamping jaw comprises: a first frame and a second frame rotatably connected to the first frame; the first frame is provided with a first driving member and a second driving member, the second frame is provided with a wiping portion and a clamping jaw assembly, the second frame is transmission-connected to the second driving member, and the second driving member is used to drive the second frame to rotate relative to the first frame; the clamping jaw assembly comprises a transmission member transmission-connected to the first driving member, and a clamping member hinged to the transmission member and located on both sides of the wiping portion 210; the clamping member comprises a first clamping section and a second clamping section, and the clamping member is movably connected to the second frame; the first driving member drives the transmission member and drives the clamping member to clamp or release the wiping portion 210.
[0037] It is understood that the first frame 100 is provided with a first drive member 110 and a second drive member 120. The second drive member 120 is used to drive the second frame 200 to rotate relative to the first frame 100, while the first drive member 110 is used to drive the clamping jaw assembly 220 to tighten or loosen the wiping portion 210. During use, the clamping jaw assembly 220 clamps the wiping member and moves to the liquid inlet. The rotation of the second frame 200 then drives the wiping portion 210 to rotate and wipe the liquid inlet. The wiping member is typically a wiping paper strip, which is cut by a specialized cutting mechanism. The cut paper strips are then delivered to a predetermined location via a feed mechanism for standby use.
[0038] Reference Figure 1 、 4 The clamping member 220 includes a transmission member 221 and a clamping member 222 hingedly connected to the transmission member 221, wherein the clamping member 222 includes a first clamping section 222a and a second clamping section 222b, which are connected at an angle. The clamping member 222 is movably connected to the second frame 200. When the first driving member 110 drives the transmission member 221 and the clamping member 222 to be in the same straight line, due to the angled connection between the first clamping section 222a and the second clamping section 222b, the distance between the clamping member 222 and the wiping portion 210 is at its maximum. In other words, the clamping member 220 is opened to its maximum extent at this time. The extent of the opening is inversely proportional to the angle between the first clamping section 222a and the second clamping section 222b. Preferably, the angle is between 90° and 120°. When the first driving member 110 drives the transmission member 221 and the clamping member 222 to gradually decrease the angle between them, the clamping member 222 gradually approaches and clamps the wiping portion 210. This structure can increase the angle of the clamping member 222 and, through the principle of leverage, enable the clamping assembly to generate a greater clamping force, thereby providing a clamping jaw with a wider opening, tighter clamping, and more stable grip.
[0039] In some embodiments, the first driving member 110 is in transmission connection with the clamping assembly 220, and the second driving member 120 is in transmission connection with the second frame 200; the clamping member 222 is hinged to the second frame 200, and the first driving member 110 can drive the driving rod 300 to clamp or release the clamping member. Specifically, the first driving member 110 is a cylinder, which is in transmission connection with the clamping assembly 220 via the cylinder, thereby controlling the clamping member 222 of the clamping assembly 220 to open or tighten. The second driving member 120 is a motor, which rotates to drive the second frame 200 to rotate. The motor here is preferably a stepping motor.
[0040] In some embodiments, reference Figure 3 , further comprising a drive rod 300, one end of which is drivingly connected to the first drive member 110, and the other end of which is hingedly connected to the transmission member 221. It will be appreciated that the output end of the first drive member 110 is drivingly connected to the drive rod 300, while the drive rod 300 is hingedly connected to the transmission member 221, and is drivingly connected to the first drive member 110 via the drive rod 300 clamping assembly 220. Specifically, a floating joint is provided between the output end of the first drive member 110 and the drive rod 300 to compensate for axial, radial, or angular errors generated during installation or movement, as well as to reduce stress caused by improper docking, thereby reducing wear and extending the life of the equipment.
[0041] In some embodiments, reference Figure 3 The second frame 200 is provided with a drive tube 230, which is sleeved on the drive rod 300. The drive tube 230 is provided with a synchronous wheel. The second drive member 120 is connected to the synchronous wheel via a synchronous belt transmission. The second frame 200 is rotatably connected to the first frame 100 via the drive tube 230. The end of the drive rod 300 away from the synchronous wheel is provided with an annular connector 310, which is rotatably connected to the drive rod 300. The clamping member 222 is hinged to both sides of the annular connector 310. The second drive member 120 is used to drive the second frame 200 to rotate relative to the first frame 100. The output end of the second drive member 120 is provided with a synchronous wheel identical to that on the drive tube 230. Preferably, a synchronous belt is installed on the two synchronous wheels. The second drive member 120 drives the drive tube 230 to rotate via the synchronous belt, thereby causing the second frame 200 to rotate. Specifically, the drive tube 230 is fixedly connected to the second frame 200. The end of the drive rod 300, which is remote from the first drive member 110, is also rotatably connected to the first drive member 110 via a bearing. When the second drive member 120 drives the second frame 200 to rotate, the drive rod 300 does not rotate. The first drive member 110 drives the drive rod 300 to continuously output power to the clamping jaw assembly 220, thereby controlling the opening or tightening of the clamping jaw assembly 220.
[0042] In some embodiments, the wiping portion 210 rotates to wipe the liquid inlet. When the wiping portion 210 rotates a predetermined number of times, wiping of the liquid inlet is completed and the next wiping step is ready. Therefore, a first sensor 130 is provided on the first frame 100, and a sensing plate 250 is provided on the second frame 200. The first sensor 130 and the sensing plate 250 cooperate to detect the number of rotations of the second frame 200. In some embodiments, the first frame 100 is provided with a second sensor 140 for detecting the displacement of the drive rod 300. It is understood that the second sensor 140 can permanently detect multiple positions. For example, when the sensor detects that the drive rod 300 is in the first position, it is in the initial position. The drive rod 300 is driven by the cylinder to move. When the sensor detects that the drive rod 300 is in the second position, the drive rod 300 has reached the predetermined position, and the clamping jaw assembly 220 has tightened the wiper and is ready for the next wiping step.
[0043] In some embodiments, reference Figure 4 , further comprising a mounting block 240, which is fixedly connected to the second frame 200. The clamping members 222 are located on both sides of the mounting block 240, and the wiping portion 210 is mounted on the mounting block 240. It is understood that the wiping portion 210 and the mounting block 240 are detachably connected, and the connection method can be one of plug-in, clip-on, threaded connection, or other detachable connection methods. When different types of liquid inlets need to be wiped, the corresponding wiping portion 210 needs to be replaced. Therefore, the provision of the mounting block 240 facilitates the replacement of the wiping portion 210.
[0044] In some embodiments, reference Figure 4 , the end face of the wiping portion 210 away from the mounting block 240 is a plane, and a scraping structure 211 is provided on the end face. Specifically, the wiping portion 210 is a square cylinder, and the clamping parts 222 are respectively located on one side of the two side surfaces of the square cylinder. A scraping structure 211 is provided on the side of the wiping portion away from the mounting block 240, and the scraping structure 211 can act as a scraper when wiping the liquid injection port, thereby achieving a better wiping effect. Specifically, the scraping structure 211 protrudes from the end face, and the scraping structure 211 is a cross pattern or a pentagonal pattern. Of course, the scraping structure 211 can also be other protruding pattern structures, but the plane where the pattern structure is located is required to be parallel to the end face, that is, the pattern corresponding to the scraping structure 211 is a continuous protruding structure, so that it can act as a scraper and improve the wiping effect.
[0045] A cleaning device includes the aforementioned clamping jaws. Specifically, the device further includes a control assembly for controlling the movement of the first drive member 110, the second drive member 120, and the clamping jaw assembly 220. For example, the control assembly is used to control the rotational speed and number of revolutions of the second drive member 120 to improve wiping performance and efficiency. Improving automation through the control assembly not only helps improve production efficiency and quality, but also offers multiple benefits, including cost savings, improved safety, and environmental protection.
