[0028] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and apparatus should be considered as being part of the specification.

[0029] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of example embodiments can have different values.

[0030] It should be noted that like reference numerals and letters in the various figures indicate similar items, and thus, once any term is defined in one figure, it is not necessary to discuss it further in connection with other figures.

[0031] According to an embodiment of the present application, an oiling mechanism is provided. As shown in Figures 1 to 3 the oiling mechanism includes an oiling assembly 1 and an oil feeding assembly. The oiling assembly 1 is adapted to oil a workpiece. The oil feeding assembly includes a pressure tank and a hydraulic sensor. The pressure tank is adapted to store protective oil. An output end of the pressure tank is communicated with the oiling assembly 1. The pressure tank is capable of delivering protective oil to the oiling assembly 1. The hydraulic sensor is disposed between the pressure tank and the oiling assembly 1. The hydraulic sensor is adapted to detect the hydraulic pressure of the protective oil delivered by the pressure tank to the oiling assembly 1.

[0032] In this example, the output end of the pressure tank is communicated with the oiling assembly 1, and the pressure tank can deliver the internal protective oil to the oiling assembly 1 in a pressurized manner. Then, the oiling assembly 1 can perform oiling on the to-be-oiled area of the workpiece. The hydraulic sensor is arranged between the pressure tank and the oiling assembly 1, and the hydraulic sensor can detect the hydraulic pressure of the protective oil delivered by the pressure tank to the oiling assembly 1, so that the pressure value in the pressure tank and the pressure value detected by the hydraulic sensor are kept corresponding, thereby facilitating to improve the accuracy of the delivery of the protective oil from the pressure tank to the oiling assembly 1.

[0033] In this example, the hydraulic sensor is arranged between the pressure tank and the oiling assembly 1. For example, the pressure tank can be communicated with the oiling assembly 1 through a conduit or an oil delivery channel, and the hydraulic sensor is installed on the conduit or the oil delivery channel and located between the pressure tank and the oiling assembly 1, and the hydraulic sensor can detect the oil pressure in the conduit or the oil delivery channel. According to the required amount of oil delivered to the oiling assembly 1, pressure is applied to the pressure tank, so that a certain amount of protective oil can be pressed into the conduit or the oil delivery channel and flow to the oiling assembly 1. The hydraulic sensor can detect the oil pressure in the conduit or the oil delivery channel. The pressure value in the pressure tank and the pressure value detected by the hydraulic sensor are kept corresponding, that is, the pressure value of the hydraulic sensor is equal to or close to the pressure in the pressure tank, so that the protective oil pressed from the pressure tank can all flow into the oiling assembly 1, thereby improving the accuracy of the delivery of the protective oil from the pressure tank to the oiling assembly 1, and realizing the quantitative oiling of the workpiece, so as to avoid too little or too much oiling of the workpiece.

[0034] In this example, the workpiece can be a cylindrical battery, and the oiling assembly 1 can apply a certain amount of protective oil to the to-be-oiled area on the end cover plate of the battery, so as to play a role of corrosion prevention, rust prevention and oxidation resistance. Of course, the workpiece can also be other types of parts, which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0035] In one example, as shown in Figure 1 The oil feeding assembly further comprises a fluid control valve 21 arranged between the hydraulic sensor and the oiling assembly 1, and the fluid control valve 21 is adapted to control the flow of the protective oil into the oiling assembly 1.

[0036] In this example, the pressure tank delivers the protective oil to the oiling assembly 1 through a conduit or an oil delivery channel, and the fluid control valve 21 can be arranged on the conduit or the oil delivery channel to control the conduction or closing of the conduit or the oil delivery channel. The fluid control valve 21 is arranged between the hydraulic sensor and the oiling assembly 1, and when it is needed to deliver the protective oil to the oiling assembly 1, pressure is applied to the inside of the pressure tank to press the protective oil into the conduit or the oil delivery channel. After the hydraulic value detected by the hydraulic sensor corresponds to the internal pressure of the pressure tank, the fluid control valve 21 is opened, so that the protective oil can flow to the oiling assembly 1.

[0037] In this example, the fluid control valve 21 can be a shut-off valve or the like, which can be determined by those skilled in the art according to actual conditions, and is not specifically limited herein.

[0038] In one example, the oil feeding assembly further comprises a solenoid valve, which is adapted to control the opening or closing of the fluid control valve 21.

[0039] In this example, the opening and closing of the fluid control valve 21 is controlled by the solenoid valve, which has a fast response speed, which can reach milliseconds. Moreover, the solenoid valve is easy to operate, and can be connected to a computer for operation, thereby avoiding the cumbersome manual operation. The solenoid valve has a small size, which is convenient for installation and maintenance. In addition, due to its light and beautiful characteristics, the solenoid valve can be easily integrated together, thereby reducing the floor area and improving the space utilization.

[0040] In one example, the oil outlet of the pressure tank is located lower than the oil inlet of the oil application assembly 1, or the oil outlet of the pressure tank is flush with the oil inlet of the oil application assembly 1.

[0041] In this example, the oil outlet of the pressure tank can be located at the bottom end of the pressure tank, and the oil outlet is communicated with the oil inlet of the oil application assembly 1 through a conduit or an oil feeding channel. When the pressure tank needs to deliver protective oil to the oil application assembly 1, the pressure tank can be pressurized by inflating. The oil outlet of the pressure tank is located lower than the oil inlet of the oil application assembly 1, or the oil outlet of the pressure tank is flush with the oil inlet of the oil application assembly 1, thereby avoiding the protective oil in the pressure tank from flowing to the oil application assembly 1 due to gravity. Therefore, a control valve does not need to be additionally provided at the oil outlet of the pressure tank, or even if a control valve is provided at the oil outlet of the pressure tank, the control valve can be set to an open state, and the operation of opening the control valve every time the oil is delivered and closing the control valve after the oil is delivered is not needed. Therefore, it is beneficial to save the operation process.

[0042] In one example, as shown in Figure 1 and Figure 3 The oil application assembly 1 comprises an oil application member 11, the output end of the oil feeding assembly is provided with a liquid injection member 22, the liquid injection member 22 can inject protective oil into the oil application member 11, and the liquid injection member 22 is fixedly arranged relative to the oil application member 11.

The liquid injection member 22 can be a liquid injection needle. One end of the oil applying member 11 is provided with a brush member 111, the liquid injection needle can extend into the oil applying member 11 and extend to the position of the brush member 111, so that the protective oil can be injected into the brush member 111 through the liquid injection needle, and the brush member 111 can apply the protective oil to the oil applying area of the workpiece. The liquid injection member 22 is fixedly arranged relative to the oil applying member 11, so that the protective oil can be stably delivered to the oil applying member 11.

[0044] As shown in the example, Figure 1 and Figure 3 in this example, the fluid control valve 21 is located on one side of the oil applying member 11, and the side of the oil applying member 11 away from the fluid control valve 21 is provided with a brush member 111. The oil applying member 11 is provided with an avoiding hole extending to the position of the brush member 111, and the liquid injection needle can extend into the avoiding hole.

[0045] In this example, the brush member 111 can have a ring structure, that is, a plurality of bristles are arranged in a circumferential direction to form a ring-shaped brush member 111, and the brush member 111 can apply a ring-shaped protective oil on the surface of the workpiece along one end in the axial direction. Of course, the specific shape of the brush member 111 can be set according to the shape of the oil applying area on the workpiece by those skilled in the art, which is not limited here.

[0046] In this example, the oil applying member 11 further comprises a rotating motor, which can drive the brush member 111 to rotate, that is, the bristles are fixed on a bristle plate, and the motor drives the bristle plate to rotate, so as to drive the brush member 111 to rotate, for example, the brush member 111 rotates around the central axis, thereby facilitating uniform oil application on the workpiece.

In this example, the oiling member 11 is arranged as movable, and the workpiece is placed on the support member 12, and the oiling member 11 is movable towards the support member 12, i.e. the oiling member 11 is movable towards the oiling area of the workpiece, so that the oiling member 11 can be in contact with the oiling area of the workpiece, thereby applying the protective oil to the workpiece. Alternatively, the support member 12 can be arranged as movable, i.e. the workpiece is placed on the support member 12, and the support member 12 can drive the workpiece to move towards the oiling member 11. Alternatively, the oiling member 11 and the support member 12 can be arranged as movable, and after the workpiece is placed on the support member 12, the support member 12 and the oiling member 11 can move towards each other, thereby improving the oiling efficiency. Of course, the specific arrangement of the oiling member 11 and the support member 12 can be determined by the actual situation, and is not limited herein.

[0049] In this example, the workpiece is placed on the support member 12, and one side of the workpiece can be adsorbed by the magnetic member, thereby positioning and fixing the workpiece. Alternatively, the support member 12 can be provided with a clamping jaw, and the workpiece can be clamped by the clamping jaw, thereby positioning and fixing the workpiece. Alternatively, the support member 12 can position the workpiece by other fixing structures. The specific arrangement can be determined by the actual situation, and is not limited herein.

[0050] In one example, as shown in Figures 1 to 3 The oiling assembly 1 further comprises a mounting seat 13, and the oiling member 11 is slidingly arranged in the mounting seat 13.

[0051] In this example, after the workpiece is fixedly placed on the support member 12, the oiling member 11 can move along the mounting seat 13 towards the support member 12, i.e. the oiling member 11 can move towards the oiling area of the workpiece, so that the oiling member 11 can be in contact with the oiling area of the workpiece, thereby applying the protective oil to the workpiece.

[0052] In one example, as shown in Figure 1 and Figure 3 The oiling assembly 1 further comprises a first connecting block 18, the first connecting block 18 is slidingly arranged in the mounting seat 13, and the oiling member 11 and the liquid injection member 22 are respectively arranged in the first connecting block 18.

[0053] In this example, the oiling member 11 and the liquid injection member 22 are respectively fixedly arranged in the first connecting block 18, and the first connecting block 18 is slidingly arranged in the mounting seat 13. The first connecting block 18 can drive the oiling member 11 and the liquid injection member 22 to move along the mounting seat 13. For example, as shown in Figure 3As shown, the oiling member 11 can be connected to the first connecting block 18 by clamping or fastening with screws or the like. The liquid injection member 22 is a liquid injection needle arranged at the liquid outlet end of the fluid control valve 21.

That is, the fluid control valve 21 is connected to the third connecting block 23 by clamping or fastening with screws or the like, and the third connecting block 23 is connected to the first connecting block 18 by clamping or fastening with screws or the like.

[0054] Of course, the specific connection mode of the oiling member 11 and the liquid injection member 22 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0055] In this example, the mounting seat 13 is provided with a sliding rail 131, and the first sliding block 14 is slidingly arranged on the sliding rail 131. The first connecting block 18 can be connected to the first sliding block 14 by clamping or fastening with screws or the like. The first connecting block 18 can slide along the sliding rail 131 through the first sliding block 14. Wherein, the first connecting block 18 is mounted on the first sliding block 14, and the first sliding block 14 is slidingly connected to the sliding rail 131, thereby facilitating the disassembly, maintenance and installation of the oiling member 11 as a whole.

[0056] In one example, as shown in Figures 1 to 3 The oiling assembly 1 further comprises a second connecting block 19, the second connecting block 19 is slidingly mounted on the mounting seat 13, the first connecting block 18 and the second connecting block 19 are elastically connected, and the second connecting block 19 can drive the first connecting block 18 to slide along the mounting seat 13.

The first connecting block 18 and the second connecting block 19 are elastically connected, thereby being able to buffer the oiling member 11 to avoid damage to the oiling member 11 or the workpiece due to excessive pressure. Moreover, the elastic connection between the first connecting block 18 and the second connecting block 19 is also conducive to the oiling member 11 being able to closely contact the surface of the workpiece, thereby improving the oiling effect.

[0058] As shown in Figure 2 and Figure 3As shown, the first connecting block 18 and the second connecting block 19 are connected by a guide rod 17. One end of the guide rod 17 passes through the second connecting block 19 and then connects to the first connecting block 18.

[0059] like Figure 3 As shown, in this example, the oiling assembly 1 also includes a second slider 15, which is slidably mounted on the slide rail 131. A second connecting block 19 can be connected to the second slider 15 via a snap-fit ​​or screw fastener connection.
