[0002] The air conditioning compressor is the heart of the air conditioner. It is usually installed in the outdoor unit and is used to compress the refrigerant. It plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circulation loop. The production process of the compressor involves multiple links such as raw material preparation, design and manufacturing, processing and assembly, commissioning and testing, process control and quality management. Among them, quality management is to check whether the various performances of the compressor meet the standards.

On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0037] The air conditioning compressor is the heart of the air conditioner. It is usually installed in the outdoor unit and is used to compress the refrigerant. It plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circulation loop. The production process of the compressor involves multiple links such as raw material preparation, design and manufacturing, processing and assembly, debugging and testing, process control and quality management. Among them, quality management is to check whether the various performances of the compressor are up to standard. For compressors that have passed the inspection, the oil stains splashed during the test need to be cleaned before packaging and delivery. If the oil stains are not wiped clean, it will affect the assembly of the compressor in the air conditioner, and even cause the exhaust pipe of the compressor to be unable to be welded to the refrigerator circulation loop. Therefore, the compressor manufacturer will arrange employees to wipe the exhaust pipe of each compressor clean before the compressor leaves the factory, but manual wiping is inefficient, and the staff is prone to fatigue. The compressor is prone to missing wiping during long-term work. Based on this, the present application provides a compressor exhaust pipe oil wiping device.

[0038] Example 1

[0039] like Figure 1-Figure 5As shown, this embodiment provides a compressor exhaust pipe oil wiping device, including a bracket 1;

[0040] The bracket 1 is provided with a lifting drive device 4.

[0041] A rotating wiping head 5 is disposed at the output end of the lifting drive device 4 , and the lifting drive device 4 drives the rotating wiping head 5 to move along the height direction of the bracket 1 .

[0042] The bracket 1 is used to support the lifting drive device 4 and the rotating wiping head 5. It should be noted that the oil wiping device of the present application also includes a controller, and a sensor for detecting the position of the compressor is provided on the bracket 1. The controller and the sensor are used to control the operation of the lifting drive device 4 and the rotating wiping head 5 according to the information fed back by the sensor.

[0043] The device can drive the rotary wiping head 5 to extend into the exhaust pipe of the compressor through the lifting drive device 4, and the exhaust pipe of the compressor can be cleaned and wiped by rotating the rotary wiping head 5 in the exhaust pipe of the compressor. The entire wiping process does not require manual participation, which can save human resources for cleaning the compressor, improve the wiping efficiency of the compressor, and is less likely to cause the compressor to be missed, which helps to ensure the factory quality of the compressor, thereby improving the competitiveness of the enterprise.

[0044] Example 2

[0045] like Figure 1-Figure 5 As shown, this embodiment includes the above-mentioned compressor exhaust pipe oil wiping device, which includes a bracket 1;

[0046] The bracket 1 is provided with a lifting drive device 4.

[0047] A rotating wiping head 5 is disposed at the output end of the lifting drive device 4 , and the lifting drive device 4 drives the rotating wiping head 5 to move along the height direction of the bracket 1 .

[0048] In this embodiment, an incoming material sensor is further disposed on the bracket 1 . The incoming material sensor is disposed close to the lifting drive device 4 and is disposed toward the bottom of the bracket 1 .

[0049] The incoming material sensor is used to check whether there is a compressor under the rotating wiping head 5, so as to ensure that the wiping device can wipe the compressor passing under the rotating wiping head 5 without missing any part.

[0050] The incoming material sensor can be a photoelectric sensor to detect whether the compressor reaches below the rotating wiping head 5. When the compressor reaches below the rotating wiping head 5, the lifting drive device 4 is controlled to drive the rotating wiping head 5 to move downward so as to enter the compressor exhaust pipe for wiping operation.

[0051] In a more preferred embodiment, multiple incoming material sensors can be provided to better determine whether the compressor has been delivered to the desired position.

[0061] In this embodiment, a first incoming material sensor is arranged upstream of the bracket 1 to form a pre-judgment position, and a second incoming material sensor is arranged at the bottom of the bracket 1 to form an operating position. When the first incoming material sensor detects that the compressor on the conveyor line 2 passes by, the lifting drive device 4 starts to start, and when the second incoming material sensor detects that a sensor passes under the bracket 1, the blocking cylinder 31 starts and drives the limit plate 32 to limit the compressor so that the compressor no longer moves. Synchronously, the lifting drive device 4 drives the rotating wiping head 5 to enter the exhaust pipe of the compressor for wiping. This control method can save the time for the rotating wiping head 5 to enter the exhaust pipe of the compressor, thereby improving the wiping efficiency of the compressor.

[0133] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a restriction. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in the subsequent accompanying drawings.

[0134] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0135] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0136] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0137] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
