[0039] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] Embodiment 1:

[0042] This embodiment provides a battery filling port wiping device, comprising:

[0043] An unwinding mechanism 1, the unwinding mechanism 1 is used for unwinding the wiping tape 5;

[0044] A reeling mechanism 2, the reeling mechanism 2 is used to reel in the used wiping tape 5;

[0045] The wiping mechanism includes a turntable assembly 3 and a plurality of wiping probes 4. The turntable assembly 3 is rotatably arranged between the unwinding mechanism 1 and the rewinding mechanism 2. The wiping belt 5 passes through the lower part of the turntable assembly 3. The plurality of wiping probes 4 are arranged in a ring array along the circumference of the turntable assembly 3, and the wiping probes 4 are telescopically mounted on the turntable assembly 3.

[0046] The control mechanism is arranged on the turntable assembly 3 and is used to control the wiping probe 4 to extend and abut against the wiping belt 5 .

[0047] In this technical solution, if Figure 1 As shown, after the battery is filled with liquid during the production process, it passes through the bottom of the battery filling port wiping device through a conveying device. The conveying device can be a conveyor belt. The unwinding mechanism 1 and the winding mechanism 2 control the wiping belt 5 to pass through the top of the conveyor belt and the bottom of the turntable assembly 3. When the battery on the conveyor belt passes under the turntable assembly 3, the control mechanism controls the wiping probe 4 located at the bottom of the turntable assembly 3 to extend and abut against the wiping belt 5 and insert it into the filling hole of the battery to wipe the residual electrolyte on the battery filling hole. When the battery is about to leave from the bottom of the turntable assembly 3, the control mechanism controls the wiping probe 4 to retract and withdraw from the filling hole, thereby completing the cleaning of the battery filling hole.

[0048] While the conveyor belt is working to transport the batteries, the turntable assembly 3 rotates, and the time required for the two adjacent wiping probes 4 on the turntable assembly 3 to rotate is exactly equal to the time required for the two adjacent batteries on the conveyor belt to move, which can prevent the same wiping probe 4 from continuously wiping the battery injection hole and affecting the wiping effect. In addition, a cleaning mechanism can be set or the used wiping probe 4 can be cleaned manually periodically to prevent the wiping probe 4 from being attached with electrolyte crystals due to long-term use.

[0049] To sum up, by using the battery filling port wiping device, there is no need to manually wipe the battery filling hole, which effectively improves work efficiency, reduces a lot of labor cost investment, and has higher economic benefits. In addition, the turntable wiping head structure ensures that each time the battery filling port is wiped, the corresponding wiping head has been cleaned, avoiding secondary pollution and other problems.

[0050] Embodiment 2:

[0051] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] Further, the turntable assembly 3 includes:

[0053] A disk body 31, wherein a plurality of through holes 32 are provided on the outer periphery of the disk body 31;

[0054] A rotating shaft 33 connected to the disc body 31;

[0055] A first driving member 34, a driving end of the first driving member 34 is connected to the rotating shaft 33, and is used to control the rotation of the rotating shaft 33;

[0056] The wiping probe 4 is telescopically installed at the through hole 32 .

[0057] In this technical solution, if Figure 3 As shown, the disk body 31 is composed of a first shell 311, a second shell 312 and a third shell 313. The first shell 311, the second shell 312 and the third shell 313 can be installed and connected together by setting fasteners, or can be fixed and connected together by welding. A plurality of through holes 32 are provided on the second shell 312, and a plurality of wiping probes 4 are telescopically installed at each through hole 32. The third shell 313 is connected to one end of the rotating shaft 33, and the other end of the rotating shaft 33 is connected to the driving end of the first driving member 34. The first driving member 34 can be a motor, and the motor is used to control the rotation of the rotating shaft 33, thereby driving the disk body 31 to rotate as a whole, thereby realizing the rotation function of the turntable assembly 3.

[0058] Embodiment 3:

[0059] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] Furthermore, the control mechanism includes:

[0061] Cam 6, cam 6 is rotatably mounted on the rotating shaft 33 and is located in the disc body 31;

[0062] A driving module, the driving module is used to control the swing of the cam 6;

[0063] Among them, a plurality of wiping probes 4 can be movably arranged on the cam 6 along the outer periphery of the cam 6 .

[0064] In the present technical solution, the control mechanism is composed of a cam 6 and a driving module. The cam 6 is rotatably mounted on the rotating shaft 33 by setting a bearing and is located inside the disk body 31, and the protrusion of the cam 6 is located directly below. The working principle of the control mechanism is as follows: when the battery passes directly below the disk body 31, one of the wiping probes 4 on the disk body 31 also moves to the position directly below as the disk body 31 rotates, and the wiping probe 4 abuts against the protrusion of the cam 6, so that the wiping probe 4 extends to cooperate with the wiping belt 5 to clean the injection hole of the battery. After cleaning is completed, the protrusion of the cam 6 swings in the opposite direction of the rotation of the disk body 31, thereby separating from the wiping probe 4 at the bottom of the disk body 31, so that the wiping probe 4 retracts and exits from the injection hole of the battery, and then before the next wiping probe 4 rotates to the bottom, the protrusion of the cam 6 swings in the direction of rotation of the disk body 31 to restore to the original position.

[0065] Embodiment 4:

[0066] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] Furthermore, the cam 6 also includes:

[0068] A sleeve 7, which is rotatably sleeved on the rotating shaft 33 and connected to the cam 6;

[0069] The driving module is used to control the rotation of the sleeve 7.

[0070] Furthermore, the driving module includes:

[0071] A second driving member 8;

[0072] A driving gear 81, the driving gear 81 is mounted on the driving end of the first driving member 34;

[0073] A driven gear 82, the driven gear 82 is mounted on the sleeve 7;

[0074] The driving gear 81 and the driven gear 82 are meshed with each other.

[0075] In the present technical solution, one end of the sleeve 7 is fixedly connected to the cam 6, and the other end is connected to the driven gear 82. The second driving member 8 can be a motor, which controls the rotation of the driving gear 81 and utilizes the meshing of the driving gear 81 and the driven gear 82 to drive the sleeve 7 to rotate, thereby realizing the swinging function of the cam 6 on the rotating shaft 33.

[0076] Furthermore, a limiting section 35 is provided on the rotating shaft 33, and the limiting section 35 abuts against the end of the sleeve 7 away from the cam 6. Through this structural design, the axial movement of the cam 6 on the rotating shaft 33 is limited, so that the internal structure of the battery filling port wiping device is more stable, and unnecessary axial displacement of the cam 6 during operation is avoided.

[0077] Embodiment 5:

[0078] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] Further, the wiping probe 4 includes:

[0080] A fixed seat 41, the fixed seat 41 is movably disposed on the cam 6 along the outer periphery of the cam 6 and is located inside the disc body 31;

[0081] The probe 42 is disposed on the fixing seat 41 and is located in the through hole 32;

[0082] The spring 43 has two ends connected to the fixing seat 41 and the disc body 31 respectively.

[0083] In the present technical solution, when the protruding portion of the cam 6 abuts against the fixing seat 41, the spring 43 is stretched and the probe 42 moves along the axial direction of the through hole 32, and cooperates with the wiping belt 5 to extend into the injection hole to clean the injection hole. When the protruding portion of the cam 6 is separated from the fixing seat 41, the spring 43 retracts due to the elastic force generated by the stretching, and the probe 42 is pulled back from the injection hole, thereby realizing the retractable effect of the wiping probe 4.

[0084] Furthermore, a plurality of positioning posts 36 are provided in the disc body 31, and the spring 43 is sleeved on the positioning posts 36. Through this structural design, the expansion and contraction stability of the spring 43 is enhanced, and unnecessary radial deviation of the spring 43 during the expansion and contraction process is avoided, so that the probe 42 can be stably extended into the injection hole and withdrawn from the injection hole.

[0085] Embodiment 6:

[0086] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0087] Furthermore, the wiping tape 5 is any one of non-woven fabric and paper tape.

[0088] In the present technical solution, the wiping tape 5 can be made of any one of non-woven fabrics or paper tapes. Non-woven fabrics and paper tapes usually have good water absorption and can quickly absorb and remove the liquid in the injection hole, thereby making the cleaning work more efficient. In addition, non-woven fabrics and paper tapes are more easily adapted to various surfaces and shapes, so that they can better cooperate with the probe 42 to enter the injection hole to clean the injection hole, which is more reliable and practical.

[0089] Embodiment 7:

[0090] This embodiment provides a battery filling port wiping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] Furthermore, when the wiping head 4 is in the retracted state, a portion of the wiping head 4 extends out of the outside of the turntable assembly 3 .

[0092] In the present technical solution, when the wiping head 4 is in a retracted state and is not at the lower end of the turntable assembly 3, the head of the wiping head 4 extends out of the turntable assembly 3, which is beneficial for cleaning the wiping head 4 that has completed the wiping work so as to better prepare for the next wiping operation.

[0093] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
