Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to an oiling apparatus and oiling equipment. Background Technology

[0002] During the battery manufacturing process, after the battery cell casing and cover are sealed together, an oiling device is used to apply protective oil to local areas of the battery cell, avoiding the electrical contact area of ​​the battery cell. This not only serves to prevent rust and corrosion, but also does not affect the electrical contact function of the battery cell.

[0003] After prolonged use, the oiling device may age or be damaged, making it impossible to guarantee that the amount of oil applied is within the preset range. If the amount of oil applied is too little, the area that needs to be oiled cannot be completely coated, which can lead to the battery cells being prone to rusting. Furthermore, the current oiling device is difficult to inspect and maintain. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the oiling device 100 of some embodiments of this application includes a first support 110, a gripper mechanism 120, and an oiling mechanism 130. The gripper mechanism 120 is mounted on the first support 110 and is used to grip the battery cell 200. The oiling mechanism 130 includes a second support 131, an oiling assembly 132, an oil reservoir 133, and a maintenance tube 134. The oiling assembly 132 and the oil reservoir 133 are mounted on the second support 131. The maintenance tube 134 is disposed between the oiling assembly 132 and the oil reservoir 133. One end of the oiling assembly 132 near the gripper mechanism 120 forms an oiling end 1363, and the other end extends through the maintenance tube 134 and into the oil reservoir 133. The second support 131 can drive the oiling assembly 132 closer to the gripper mechanism 120 so that the oiling end 1363 applies protective oil to the area 210 of the battery cell 200 to be oiled. The inspection pipe 134 includes a first end 1341 and a second end 1342. The first end 1341 is detachably connected to the oiling assembly 132, and the second end 1342 is detachably connected to the oil reservoir 133.

[0030] The battery cell 200 has an oil-to-be-coated area 210 on one side along direction Z. The oiling assembly 132 is disposed on the side of the gripper mechanism 120 near the oil-to-be-coated area 210. The oiling end 1363 of the oiling assembly 132 matches the shape of the oil-to-be-coated area 210. The second bracket 131 drives the oiling assembly 132 to approach the gripper mechanism 120, pressing the oiling end 1363 and the oil-to-be-coated area 210 against each other to coat the oil-to-be-coated area 210 with protective oil.

[0031] The oiling device 100 of this application embodiment is provided with a maintenance tube 134. The first end 1341 of the maintenance tube 134 is detachably connected to the oiling component 132, and the second end 1342 is detachably connected to the oil storage component 133. When maintenance is required, the maintenance tube 134 can be removed, and the part of the oiling component 132 that penetrates the maintenance tube 134 can be replaced or repaired. This ensures that the oiling component 132 is in normal condition and that the amount of oil applied is within a preset range. This allows for precise application of protective oil to the oiling area 210 of the battery cell 200, resulting in better oiling quality and improved safety performance of the battery cell 200.

[0032] like Figure 3 As shown, in some embodiments of this application, the oil-to-be-coated area 210 of the battery cell 200 refers to the annular area of ​​the bottom wall of the battery cell 200. Since there are weld marks after the bottom wall is welded to the negative electrode adapter, protective oil needs to be applied here to improve the anti-rust function. At the same time, the central area of ​​the bottom wall is left open to facilitate conductive connection with the external busbar.

[0033] In other embodiments, the gripper mechanism 120 can also be used to grip other types of workpieces that need to be oiled, and the shape of the oiling end 1363 can also be square, round, etc.

[0034] The gripper mechanism 120 includes two gripper assemblies, which are spaced apart along the Z direction, and together they grip the battery cell 200.

[0035] like Figure 3 and Figure 5 As shown, in some embodiments of this application, the oiling assembly 132 includes a support block 135 and an oiling component 136. The support block 135 is mounted on the second bracket 131, and the oiling component 136 includes an oil-absorbing cloth 1361. The oil-absorbing cloth 1361 wraps around one end of the support block 135 near the gripper mechanism 120 to form an oiling end 1363.

[0036] The oil-absorbing cloth 1361 has an oil-absorbing effect; for example, the oil-absorbing cloth 1361 can be non-woven fabric or cotton cloth. The oil-absorbing cloth 1361 is partially immersed in the protective oil of the oil reservoir 133, or is immersed in the protective oil of the oil reservoir 133 via the oil-absorbing rope 1362 described below, thereby maintaining a wetted state. When the oil-applying end 1363 is pressed against the oil-to-be-applied area 210 of the battery cell 200, the protective oil wetted on the oil-absorbing cloth 1361 can be applied to the oil-to-be-applied area 210.

[0037] The surface of the second bracket 131 near the gripper mechanism 120 along the Z direction is recessed to form a groove. The support block 135 is fixed inside the groove by a threaded part. The side of the support block 135 near the gripper mechanism 120 protrudes from the first surface 1312 of the second bracket 131 and is wrapped by an oil-absorbing cloth 1361 to form an oiling end 1363, so that the oiling surface of the oiling end 1363 is significantly higher than the first surface 1312, and has a higher oiling precision.

[0038] With this setup, the oil-absorbing cloth 1361 can be soaked in protective oil to accurately apply oil to the oil-to-be-oiled area 210 of the battery cell 200. There will be no oil splashing or splattering during the oiling process, thus achieving high oiling accuracy.

[0039] In other embodiments, the oiling assembly 132 may also use a roller brush, eccentric brush or other processes to apply oil to the oil-to-be-oiled area 210 of the battery cell 200.

[0040] like Figure 3 and Figure 5 As shown, in some embodiments of this application, the support block 135 has a first flange opening 1353 on the side along direction Z near the gripper mechanism 120, and an oil-absorbing cloth 1361 wraps around the first flange opening 1353 to form an annular oiling end 1363. Correspondingly, the oiling area 210 of the battery cell 200 is also annular.

[0041] In other embodiments, the support block 135 may also be square or cylindrical, etc.

[0042] like Figure 3 and Figure 5 As shown, in some embodiments of this application, the oiling mechanism 130 further includes a pressure block 1364, which is fixed to the support block 135 from the oiling end 1363 side, and a portion of the oil-absorbing cloth 1361 is pressed between the support block 135 and the pressure block 1364.

[0043] The pressure block 1364 has a ring-shaped structure. The pressure block 1364 is fitted onto the first flange opening 1353 of the support block 135 and is fixed to the support block 135 by threaded parts. One edge of the oil-absorbing cloth 1361 is pressed between the support block 135 and the pressure block 1364, and the other side extends into the interior of the first flange opening 1353 to wrap the first flange opening 1353, thereby forming the oiling end 1363.

[0044] By setting the pressure block 1364, the edge of the oil-absorbing cloth 1361 can be fixed, so that the oil-absorbing cloth 1361 tightly wraps the support block 135, improving the shape accuracy of the oiling end 1363, and thus improving the oiling accuracy.

[0045] In other embodiments, there may be multiple pressure blocks 1364, which are circumferentially spaced around the support block 135; the edge of the oil-absorbing cloth 1361 may also extend beyond the pressure block 1364.

[0046] like Figure 3 As shown, in some embodiments of this application, the support block 135 is provided with a through first channel 1351, which is connected to the inspection pipe 134, and a portion of the oil-absorbing cloth 1361 extends into the first channel 1351.

[0047] The first channel 1351 extends through the support block 135 along the direction Z, and the first flange 1353 forms part of the first channel 1351; the maintenance pipe 134 extends along the direction Z, the oil storage component 133 is disposed on one side of the support block 135 along the direction Z, and one side of the oil-absorbing cloth 1361 extends into the first channel 1351 from the first flange 1353.

[0048] The second support 131 is also provided with a second channel 1313, which runs through the second support 131 along the direction Z. The first channel 1351, the second channel 1313 and the maintenance pipe 134 are connected in sequence.

[0049] This configuration allows the oil-absorbing cloth 1361 to be enclosed inside the oiling assembly 132, reducing the amount of protective oil evaporation and facilitating precise control of the amount of oil applied.

[0050] In other embodiments, the first channel 1351 and the pressure block 1364 may not be provided, and the oil-absorbing cloth 1361 may wrap the support block 135 and form a square or round oiling end 1363.

[0051] like Figure 3 As shown, in some embodiments of this application, the oiling assembly 132 further includes a connecting flange 137, which is installed on the side of the second bracket 131 away from the gripper mechanism 120, and the first end 1341 of the inspection tube 134 is sleeved on the connecting flange 137.

[0052] The connecting flange 137 is installed on the second bracket 131 along the direction Z by a threaded fitting. The connecting flange 137 has a second flange port 1374. The first end 1341 of the inspection pipe 134 is fitted onto the second flange port 1374. The connecting flange 137 and the inspection pipe 134 are sealed together by an interference fit.

[0053] This configuration allows for a simple and reliable detachable connection between the inspection pipe 134 and the oiling assembly 132 via the connecting flange 137.

[0054] In other embodiments, the connecting flange 137 can also be directly connected to the support block 135; or the first end 1341 of the inspection pipe 134 can be fixed to the second flange port 1374 by means of a retaining ring or the like.

[0055] like Figure 3 As shown, in some embodiments of this application, the support block 135 is provided with a through first channel 1351, the second bracket 131 is provided with a through second channel 1313, and the connecting flange 137 is provided with a through third channel 1371. The first channel 1351, the second channel 1313 and the third channel 1371 are connected in sequence. A sealing element 1372 is provided between the support block 135 and the connecting flange 137 so that the second channel 1313 and the third channel 1371 are sealed and connected.

[0056] The third channel 1371 passes through the connecting flange 137 in the Z direction and is connected to the inspection pipe 134. The connecting flange 137 has a mounting groove 1373 on the side near the second bracket 131. The sealing element 1372 is installed in the mounting groove 1373 to circumferentially seal the second channel 1313 and the third channel 1371.

[0057] This configuration allows for a sealed connection between the second bracket 131 and the connecting flange 137, reducing oil leakage and spillage, facilitating the calculation of the amount of oil applied, and thus improving the accuracy of oil application.

[0058] like Figure 5 As shown, in some embodiments of this application, the oiling component 136 further includes an oil-absorbing rope 1362, which is connected to the oil-absorbing cloth 1361. The oil-absorbing rope 1362 extends out from the second end 1342 of the inspection pipe 134 and then into the oil storage component 133.

[0059] The oil-absorbing rope 1362 and the oil-absorbing cloth 1361 can be integrally formed, that is, they are the same piece of cloth made of the same material; the oil-absorbing rope 1362 and the oil-absorbing cloth 1361 can also be connected by layering and pressing.

[0060] like Figure 4 As shown, the oil storage component 133 has an oil storage cavity 1331 inside, and a third flange opening 1333 is provided on the side near the oiling component 132 along the Z direction to form the bottle mouth of the oil storage cavity 1331. The second end 1342 of the inspection pipe 134 is sleeved on the third flange opening 1333, and the oil storage component 133 and the inspection pipe 134 are sealed together by interference fit.

[0061] The end of the oil-absorbing rope 1362 extends into the oil storage chamber 1331 through the inspection pipe 134 and is immersed in the protective oil in the oil storage chamber 1331. The head end of the oil-absorbing rope 1362 and the oil-absorbing cloth 1361 are pressed together between the pressure block 1364 and the support block 135, pass around the first flange opening 1353 of the support block 135 and enter the first channel 1351, then pass through the second channel 1313 and the third channel 1371 and enter the inspection pipe 134.

[0062] By setting up the oil-absorbing rope 1362, the capillary action of the oil-absorbing rope 1362 can be used to evenly provide protective oil to the oil-absorbing cloth 1361, thereby improving the oil coating uniformity of the oil coating end 1363.

[0063] In other embodiments, the head of the oil-absorbing rope 1362 may also connect to the oil-absorbing cloth 1361 without bypassing the first flange opening 1353, and may be connected to one of the first channel 1351, the second channel 1313, the third channel 1371, or the inspection pipe 134.

[0064] like Figure 3 As shown, in some embodiments of this application, the first channel 1351 of the support block 135 is provided with an isolation member 1352.

[0065] The isolator 1352 substantially closes the first channel 1351 along its cross-section. For example, the isolator 1352 is a bolt, which is fixed to the support block 135 by threaded fastening, with the bolt head facing the gripper mechanism 120 in the Z direction. The isolator 1352 can also be used to fix the oil-absorbing cloth 1361, i.e., the bolt passes through the oil-absorbing cloth 1361, and the head of the bolt is used to fix the oil-absorbing cloth 1361 to the mounting post.

[0066] By setting the isolation component 1352, it is possible to ensure that the oiling component 132 can supply oil normally, and to prevent the oil from falling into the oil storage component 133 through the first channel 1351.

[0067] like Figure 1 As shown, in some embodiments of this application, the oiling mechanism 130 further includes a detection sensor 139 for detecting the remaining amount of protective oil in the oil reservoir 133.

[0068] When the detection sensor 139 detects that the level of protective oil in the oil reservoir 133 is lower than the threshold, the solenoid valve opens to replenish the protective oil in the oil reservoir 133 until the preset liquid level is reached and then closes.

[0069] The oil storage device 133 also includes an overflow pipe 1332. When the detection sensor 139 detects that the remaining amount of protective oil in the oil storage device 133 exceeds the threshold, the excess protective oil overflows outward from the overflow pipe 1332.

[0070] This configuration ensures that the amount of oil in the oil reservoir 133 is within a preset range, making it easy to control the amount of oil applied.

[0071] like Figure 6 As shown, in some embodiments of this application, the inspection tube 134 is provided with a transparent or semi-transparent observable area 1343.

[0072] The inspection tube 134 can be made entirely of transparent or semi-transparent material, making it easy for staff to observe from the outside whether the oil-absorbing rope 1362 is broken; the inspection tube 134 can also have a local observable area 1343, with the rest of the area being made of non-transparent material.

[0073] This configuration allows for easy and timely detection of the working status of the oiling component 132, enabling timely maintenance and repair, thereby ensuring the quality of oiling.

[0074] like Figure 2 As shown, in some embodiments of this application, the first bracket 110 and the second bracket 131 are slidably engaged by the first slider 1311. The oiling mechanism 130 also includes a buffer block 138. The first bracket 110 and the buffer block 138 are slidably engaged by the second slider 1381. An elastic element 1382 is provided between the second bracket 131 and the buffer block 138.

[0075] The first bracket 110 and the second bracket 131 are slidably engaged in the Z direction via the first slider 1311. The first bracket 110 and the buffer block 138 are slidably engaged in the Z direction via the second slider 1381. The buffer block 138 is located on the side of the oil storage component 133 away from the support block 135. The elastic element 1382 is a straight spring, and the two ends of the elastic element 1382 are respectively connected to the second bracket 131 and the buffer block 138.

[0076] By setting a buffer block 138, the impact force on the battery cell 200 when the oiling component 132 approaches the gripper mechanism 120 can be buffered, and the impact force on the battery cell 200 can be reduced when the oiling end 1363 squeezes the area to be oiled 210, thereby improving the oiling quality.

[0077] like Figure 2 As shown, in some embodiments of this application, the oiling device 100 further includes an oiling mechanism 140, which is disposed on the side of the gripper mechanism 120 opposite to the oiling mechanism 130, for applying protective oil to the area 220 of the battery cell 200 to be oiled.

[0078] The oiling mechanism 140 is fixed to the first bracket 110 and includes a motor and an eccentric brush. The eccentric brush is eccentrically set on the output turntable of the motor. The oiling area 220 of the battery cell 200 is the welding area between the cover and the shell.

[0079] The oiling mechanism 140 can apply oil to the welding area between the cover and the housing of the battery cell 200 for protection, while avoiding the terminal area of ​​the cover, thus ensuring the power connection function of the battery cell 200.

[0080] like Figure 7 As shown, the oiling apparatus 300 of some embodiments of this application includes an oiling device 100.

[0081] The oiling equipment 300 also includes a turntable 310, with a cam cylinder 320 in the middle of the turntable 310. Multiple oiling devices 100 are provided, and the multiple oiling devices 100 are circumferentially spaced on the outside of the turntable 310. The first bracket 110 of each oiling device 100 is fixedly installed on the outside of the turntable 310. The first slider 1311 is inserted into the cam groove of the cam cylinder 320 through a pivot pin. The turntable 310 rotates to drive the multiple oiling devices 100 to rotate circumferentially. Through the contour of the cam groove, the oiling mechanism 130 is driven to move closer to or further away from the battery cell 200 held by the gripper mechanism 120 in the direction Z. The oiling end 1363 and the oiling area 210 of the battery cell 200 are pressed against each other to complete the oiling action.

[0082] Due to the aforementioned characteristics of the oiling apparatus 100 in the embodiments of this application, the oiling equipment 300 also has better oiling quality, thereby improving the safety performance of the battery cell 200.

[0083] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
