[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] like Figure 1 and Figure 2As shown, the utility model provides a wiping liquid injection hole device, which includes a wiping seat 1, a rotating sleeve 2 rotatably connected to the wiping seat 1, a wiping rotation driving mechanism 3 installed on the wiping seat 1 and used to drive the rotating sleeve 2 to rotate, a bracket 4 installed at the bottom end of the rotating sleeve 2, a shaft 5 slidingly passing through the rotating sleeve 2 and the bracket 4, a lifting seat 6 that is lifted and arranged on the wiping seat 1 and rotatably connected to the top of the shaft 5, a wiping lifting driver 7 installed on the wiping seat 1 and used to drive the lifting seat 6 to rise and fall, and a wiping lifting driver 7 installed on the shaft 5. The wiping head 8 at the bottom, the connecting plate 9 installed in the middle of the shaft 5 and slidably connected to the bracket 4, and the two clamping assemblies 10 movably connected to the two ends of the connecting plate 9, the two clamping assemblies 10 are symmetrically arranged, and the clamping assembly 10 includes a connecting rod 11 and a clamping claw 12. One end of the connecting rod 11 is hinged to one end of the connecting plate 9, the top of the clamping claw 12 is hinged to the other end of the connecting rod 11, the middle of the clamping claw 12 is hinged to the bracket 4, and the bottom ends of the two clamping claws 12 are respectively arranged on both sides of the wiping head 8. At the beginning, when the wiping head 8 is at the highest position, the clamping claws 12 of the two clamping assemblies 10 are in an open clamping state; when the wiping head 8 is at the lowest position, the clamping claws 12 of the two clamping assemblies 10 are in a closed clamping (clamping) state.

[0021] In actual application, at the beginning, the clamping claws 12 of the two clamping assemblies 10 are opened, and the utility model moves to the top of the wiping cloth, and then the wiping lifting driver 7 drives the shaft 5 to move down along the rotating sleeve 2, so that the wiping head 8 is inserted into the wiping cloth. As the wiping head 8 moves down, the wiping cloth covers the wiping head 8. At the same time, the downward moving shaft 5 drives the connecting plate 9 to move down, and the downward moving connecting plate 9 drives the clamping claws 12 to close and rotate through the connecting rod 11 until the two clamps are The bottom end of the holding claw 12 clamps the wiping cloth on the side wall of the wiping head 8 to pick up the wiping cloth. Then the utility model moves the wiping cloth to the injection hole of the battery. The wiping cloth contacts the injection hole. The wiping rotation drive mechanism 3 drives the rotating sleeve 2 to rotate. The rotating rotating sleeve 2 drives the bracket 4 to rotate synchronously with the connecting plate 9, the shaft 5, the wiping head 8 and the two clamping components 10. The wiping cloth on the rotating wiping head 8 rotates and wipes the injection hole of the battery. The structural design of the utility model is reasonable and compact. The clamping component 10 is driven to open or close by the lifting of the shaft 5. The coordination linkage is good, the control system can be simplified, and the stability of picking up the wiping cloth is improved.

[0022] Specifically, the wiping lifting drive 7 can adopt a cylinder.

[0023] In this embodiment, the bracket 4 is provided with a lifting space 13, and the connecting plate 9 is lifted and arranged in the lifting space 13, and the connecting plate 9 horizontally penetrates the lifting space 13. The connecting plate 9 is lifted and lowered in the lifting space 13, so that the structure of the bracket 4 and the connecting plate 9 is compact and the lifting stability is good.

[0024] In this embodiment, the connecting plate 9 is rotatably connected with a rotating member 14, and the rotating member 14 rolls against the outer wall of the bracket 4. Specifically, the rotating member 14 is a rotating wheel or a bearing. When the connecting plate 9 is lifted and lowered in the lifting space 13, the rotating member 14 rolls along the outer wall of the bracket 4, thereby improving the lifting stability of the connecting plate 9.

[0025] Preferably, there are two rotating members 14, and the bracket 4 is located between the two rotating members 14. This structural design is conducive to the bracket 4 driving the connecting plate 9 to rotate synchronously.

[0026] In this embodiment, a quick release plate 15 is installed at the lifting end of the wiping lifting driver 7, and a quick release slot 16 is provided at the top of the lifting seat 6. The quick release plate 15 is inserted into the quick release slot 16. This structural design facilitates the disassembly and maintenance of the wiping lifting driver 7 and the lifting seat 6.

[0027] In this embodiment, the wiping rotation drive mechanism 3 includes a rotation driver 17 disposed on the wiping seat 1 and a transmission assembly 18 that is transmission-connected between the rotating end of the rotation driver 17 and the rotating sleeve 2. The rotation driver 17 drives the rotating sleeve 2 to rotate via the transmission assembly 18. Specifically, the rotation driver 17 can be a motor. In practical applications, the rotation driver 17 drives the transmission assembly 18 to transmit, and the transmission assembly 18 drives the rotating sleeve 2 to rotate.

[0028] In this embodiment, the transmission assembly 18 includes a first transmission wheel 19 mounted on the output end of the rotation driver 17, a second transmission wheel 20 mounted on the rotating sleeve 2, and a transmission bar 21 connected between the first transmission wheel 19 and the second transmission wheel 20. Specifically, when the first transmission wheel 19 and the second transmission wheel 20 are pulleys, the transmission bar 21 is a transmission belt; when the first transmission wheel 19 and the second transmission wheel 20 are sprockets, the transmission bar 21 is a transmission chain. In practical applications, the rotation driver 17 drives the first transmission wheel 19 to rotate, the rotating first transmission wheel 19 drives the second transmission wheel 20 to rotate via the transmission bar 21, and the rotating second transmission wheel 20 drives the rotating sleeve 2 to rotate synchronously.

[0029] Preferably, the second transmission wheel 20 is connected to the rotating sleeve 2 via a connecting key to ensure that the second transmission wheel 20 and the rotating sleeve 2 rotate synchronously.

[0030] In this embodiment, the wiping rotation drive mechanism 3 further includes a tensioning seat 22 slidably connected to the wiping seat 1 and a locking piece for locking the tensioning seat 22 to the wiping seat 1, and the rotation driver 17 is installed on the tensioning seat 22. In practical applications, after the locking piece loosens the tensioning seat 22, the tensioning seat 22 can move relative to the wiping seat 1 to adjust the tensioning force of the transmission bar 21 to ensure the transmission stability of the transmission bar 21. After the adjustment is completed, the locking piece locks the tensioning seat 22 on the wiping seat 1. Specifically, the locking piece can be a screw.

[0031] In this embodiment, the wiping rotation driving mechanism 3 further includes a bolt adjustment assembly 23 threadedly connected to the wiping seat 1, and the end of the bolt adjustment assembly 23 abuts against a side wall of the tensioning seat 22. After the locking piece loosens the tensioning seat 22, the bolt adjustment assembly 23 is rotated so that the end of the bolt adjustment assembly 23 abuts against the tensioning seat 22 and moves away from the shaft 5, so as to adjust the tension of the transmission bar 21.

[0032] In this embodiment, the top end of the shaft rod 5 is rotatably connected to the lifting seat 6 via a rotating joint. This structural design not only facilitates the connection between the shaft rod 5 and the lifting seat 6, but also enables the shaft rod 5 to rotate smoothly relative to the lifting seat 6.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
