Description

Technical Field

[0001] The invention relates to the technical field of greasing, and in particular to an automatic greasing device and a workpiece greasing method. Background Art

[0002] The air guide plate of the air conditioner is an important component inside the air conditioner. Its main function is to adjust the direction of the air outlet of the air conditioner to achieve uniform distribution and precise control of the indoor temperature. The air guide plate of the air conditioner usually includes an air guide plate body and a connecting shaft. The connecting shaft is connected to the drive structure so that the drive structure can drive the air guide plate to rotate. In the production process of the air conditioner, greasing the connecting shaft of the air guide plate is a key step. Its main purpose is to reduce the abnormal sound and noise generated by the continuous rotation of the air guide plate during use. The traditional greasing method of the connecting shaft relies on manual operation. The operator needs to apply a layer of grease on the surface of the connecting shaft of the air guide plate to reduce the operating noise. This greasing method that relies on manual experience has obvious defects: the traditional greasing mode has significant disadvantages. The operator relies on experience to judge the amount and effect of greasing, resulting in drastic fluctuations in greasing efficiency and quality, which is difficult to control. Long-term operation can easily cause eye fatigue, which in turn affects the accuracy of operation.

[0006] A grease coating station is provided on the main body and is located below the visual inspection system; the grease coating station includes a fixture and a grease coating structure, the grease coating structure is located on one side of the fixture, the fixture is used to clamp the workpiece to be greased, and the grease coating structure includes a grease coating nozzle for greasing the workpiece.

[0007] The device can analyze the workpiece through the visual inspection system, accurately identify the grease application location and status, and ensure the accuracy of the grease application position. Combined with the grease application structure and control system, it can achieve precise control of the grease injection amount and pressure, making the grease application thickness uniform and consistent, avoiding the situation of excessive or insufficient grease application in some parts, thereby significantly improving the lubrication effect of the workpiece.

[0037] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. 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.

[0038] During the production process, the air conditioner outdoor unit mask needs to go through multiple processes, such as stamping, surface treatment, and assembly of accessories. Between different production processes, the mask is usually hung on the hook of the hanging chain, so that the mask can be moved in an orderly manner between the processes, ensuring the continuity and smoothness of the production process, avoiding transportation delays between processes, and improving overall production efficiency.

[0039] However, when making and assembling the air conditioner outdoor unit mask, it is usually carried and removed from the hanging chain by manpower, which takes a lot of time and is extremely inefficient, seriously affecting the production progress. On the other hand, the long-term handling work makes the workers' labor intensity extremely high and puts a heavy burden on the workers' bodies. In addition, during the manual handling and assembly process, uncontrollable damage factors often occur due to differences in the degree of movement and assembly. These damages not only lead to a decline in product quality, but also cause a waste of cost, increasing the company's production costs and quality control difficulties.

[0040] Based on this, the present application provides an automatic greasing device.

[0041] Example 1

[0042] See also Figure 1-Figure 6 , this embodiment provides an automatic grease coating device, comprising:

[0043] A main body 2, on which a conveying line 6 is arranged; a visual inspection system 4 is arranged above the conveying line 6, and the visual inspection system 4 is arranged toward the conveying line;

[0044] A grease coating station is provided on the main body 2, and the grease coating station is located below the visual inspection system 4; the grease coating station includes a clamp 3 and a grease coating structure 5, and the grease coating structure 5 is located on one side of the clamp 3, and the clamp 3 is used to clamp the workpiece to be greased, and the grease coating structure 5 includes a grease coating nozzle 51 for greasing the workpiece.

[0045] Specifically, the main body 2 is the basic structure of the device, providing installation locations for various devices. In one embodiment, the main body 2 can be made of high-strength aluminum alloy to ensure the stability and durability of the overall structure.

[0046] The visual inspection system 4 is installed 30-50 cm above the conveyor line, using a high-resolution CCD camera with more than 5 million pixels, coupled with a professional optical lens and intelligent image processing software. Through precise calibration, its field of view can completely cover the workpieces on the conveyor line and ensure the clarity and accuracy of the image.

[0047] The fixture 3 of the grease application station is designed as a mechanical clamping structure that can be quickly replaced and adjusted, and is designed according to the workpiece to be greased to ensure that the workpiece can be stably clamped. If the workpiece to be greased is an air guide plate, the fixture 3 needs to ensure that the air guide plate body 2 can be stably clamped.

[0048] During the production process, the device is started and the workpiece to be greased (air guide plate) is placed at the starting end of the conveyor line. The conveyor line runs at a speed and conveys the workpiece to the bottom of the visual inspection system 4. The visual inspection system 4 is started, scans and images the workpiece, and uses an image recognition algorithm to quickly analyze the surface features, shape and size of the workpiece. These data are transmitted to the central control system of the device in real time.

[0049] When the workpiece arrives at the greasing station, the fixture 3 moves according to the instructions of the central control system, accurately clamps the workpiece, and ensures that it remains stable during the greasing process. The greasing structure 5 adjusts the position and angle of the greasing nozzle 51 under the control of the control system according to the type of workpiece and the greasing requirements, and sprays grease on the workpiece. During the greasing process, the visual inspection system 4 continuously monitors the greasing situation. If abnormal conditions such as uneven greasing or grease splashing are found, feedback is given to the control system, and the control system immediately adjusts the greasing parameters or suspends the greasing operation for correction.

[0050] After the greasing is completed, the fixture 3 releases the workpiece and transports it to the subsequent process or finished product area via the conveyor line, completing a complete greasing process.

[0051] The device can analyze the workpiece through the visual inspection system 4, accurately identify the grease application location and state, and ensure the accuracy of the grease application position. Combined with the grease application structure 5 and the control system, the grease injection amount and pressure can be accurately controlled to make the grease application thickness uniform and avoid the situation of excessive or insufficient grease application in some parts, thereby significantly improving the lubrication effect of the workpiece.

[0052] The automated greasing process greatly reduces the number of manual operations and significantly increases production speed compared to traditional manual greasing. The stable operation of the conveyor line and the efficient collaboration of each workstation can achieve continuous and uninterrupted production operations, and the work rhythm can be flexibly adjusted according to production needs, effectively meeting the needs of large-scale production, reducing production costs, and enhancing the company's competitiveness in the market.

[0053] More preferably, it also includes a grease supply system 1, which includes a grease storage tank 11, a pressure controller 12 and a grease supply device 13. The grease storage tank 11 and the grease supply device 13 are both arranged on the main body 2. The grease storage tank 11 is connected to the input port of the grease supply device 13 through a connecting pipe, and the output port of the grease supply device 13 is connected to the grease nozzle 51. The pressure controller 12 is arranged on the connecting pipe. The pressure controller 12 can control

[0054] The grease storage tank 11 is used as a storage container for lubricating grease. Its capacity is designed according to the production scale and grease frequency of the device to ensure sufficient supply of lubricating grease within a certain production cycle. The pressure controller 12 is installed on the connecting pipe connecting the grease storage tank 11 and the grease supply device 13. It is one of the core components to ensure the stability of the grease application process. During the grease application operation, the pressure controller 12 can monitor and control the pressure of the lubricating grease in the connecting pipe. When the grease nozzle 51 requires different grease injection pressures, the pressure controller 12 will adjust according to the instructions of the control system or the preset pressure parameters. For example, when greasing some workpieces with rough surfaces or high requirements for lubricating grease penetration, the pressure controller 12 will increase the pressure so that the lubricating grease can be sprayed out from the grease nozzle 51 at a higher speed and pressure, ensuring that the grease can fully fill the tiny gaps and rough surfaces of the workpiece to achieve a good lubrication effect. The grease supply device 13 is responsible for delivering the lubricating grease in the grease storage tank 11 to the grease nozzle 51 as required. It receives the regulated lubricating grease from the pressure controller 12, and pushes the lubricating grease stably to the grease nozzle 51 through the internal delivery structure, such as a gear pump or a plunger pump. During the entire grease application process, the various components of the grease supply system 1 work together to ensure that the grease nozzle 51 can continuously and stably output the lubricating grease at the required pressure and flow rate, thereby ensuring the consistency and reliability of the grease quality, meeting the grease application requirements of different workpieces, and improving the overall performance and production efficiency of the device.

[0055] Example 2

[0056] This embodiment is optimized based on embodiment 1.

[0057] See also Figure 1-Figure 6 Specifically, in this embodiment, the visual inspection system 4 includes a first guide rail 41, a first slider 43 and a visual lens 42. The first guide rail 41 spans above the conveyor line. A plurality of first sliders 43 are arranged on the first guide rail 41. Each of the first sliders 43 is provided with the visual lens 42. The visual lens 42 is arranged toward the conveyor line.

[0058] In actual use, the multiple visual lenses 42 distributed on the first guide rail 41 simultaneously shoot the parts from multiple angles, obtain the complete image information of the parts, and immediately transmit it to the central control computer. The computer uses image processing software to analyze the image and identify the type, size, shape characteristics and current grease coating status of the parts.

[0059] The visual lens 42 can slide on the first guide rail 41 through the first slider 43, so that the visual lens 42 can obtain the structural features of different parts of the workpiece. During the greasing process, the visual lens 42 continuously monitors the greasing situation. If problems such as uneven greasing, grease accumulation or missing greasing are found, feedback is immediately given to the control system. The control system will suspend the greasing operation, fine-tune the greasing parameters, and restart the greasing until the greasing quality meets the standard requirements.

[0060] Example 3

[0061] This embodiment is optimized based on embodiment 1.

[0062] See also Figure 1-Figure 6 Specifically, two clamps 3 are provided, and the two clamps 3 are relatively arranged on two opposite sides of the conveying line.

[0063] This embodiment also provides a specific structure of the clamp 3, the clamp 3 includes a bracket 32, a pneumatic clamp 31 and a rotation drive system, the bracket 32 ​​is arranged on one side of the conveyor line, and the pneumatic clamp 31 is rotatably arranged on the bracket 32;

[0064] The rotation driving system is disposed on the bracket 32 ​​, and the rotation driving system drives the pneumatic clamp 31 to rotate on the bracket 32 ​​.

[0065] More specifically, the rotation drive system includes a drive motor 35, a turntable 34 and a transmission belt 33. The drive motor 35 is fixed on the bracket 32, the turntable 34 is rotatably arranged on the bracket 32, and one side of the turntable 34 is fixedly connected to the pneumatic clamp 31 through a connecting shaft; the transmission belt 33 is connected between the output end of the drive motor 35 and the turntable 34.

[0066] The pneumatic clamp 31 is made of alloy steel with large clamping force and good wear resistance, and is rotatably mounted on the bracket 32 ​​via a pin. Its clamping surface can be provided with a buffer pad such as rubber, so that the pneumatic clamp 31 can clamp the air guide plate without causing damage to the surface of the air guide plate.

[0067] When the workpiece (wind deflector) reaches the greasing station, the clamps 3 on both sides act simultaneously under the command of the control unit. The pneumatic clamps 31 quickly clamp the workpiece under the action of air pressure to ensure that it will not move during the greasing process. Subsequently, the drive motor 35 of the rotary drive system is started, driving the turntable 34 to rotate through the transmission belt 33, and then driving the pneumatic clamps 31 to rotate on the bracket 32, so that the connecting shaft of the wind deflector can be evenly greased.

[0068] After greasing is completed, the driving motor 35 is reversed to return the pneumatic clamp 31 to the initial position, and then the pneumatic clamp 31 releases the workpiece. The greased workpiece leaves the greasing station driven by the conveyor line and enters the subsequent quality inspection and assembly links, completing a complete greasing process.

[0069] The present application sets two relative clamps 3 to apply clamping force from both sides of the workpiece at the same time. Compared with a single clamp 3, the fixing effect on the workpiece is greatly enhanced, making it more stable during the greasing process, and effectively avoiding the problem of uneven greasing or deviation caused by the shaking of the workpiece. At the same time, the rotation drive system of the clamp 3 can make the workpiece rotate at a constant speed during the greasing process, ensuring that the greasing nozzle 51 can grease the surface of the workpiece in all directions, achieving a more uniform and comprehensive greasing effect, improving the lubrication quality of the product, and extending the service life of the transmission shaft.

[0070] Example 4

[0071] This embodiment is optimized based on embodiment 1.

[0072] See also Figure 1-Figure 6 In this embodiment, two grease coating structures 5 are provided, and the two grease coating structures 5 are relatively arranged on two opposite sides of the conveying line.

[0073] In this embodiment, the grease coating structure 5 further includes a second guide rail 535, a second slider (not shown) and a grease coating box 53. The second guide rail 535 is arranged at one side of the conveying line, and the length direction of the second guide rail 535 is the same as the conveying direction of the conveying line. The second slider is arranged on the second guide rail 535, and the grease coating box 53 is fixed on the second slider.

[0074] It should be noted that the principle of the movement of the first slider on the first guide rail and the principle of the movement of the second slider on the second guide rail of the present application are the same, and both can be implemented by using a linear guide slider mechanism.

[0075] The grease coating box 53 is provided with a tooth plate 532, a transmission gear 534 and a linear drive structure 533. The linear drive structure 533 is fixed in the grease coating box 53. The output end of the linear drive structure 533 is fixedly connected to the tooth plate 532. The transmission gear 534 is rotatably disposed in the grease coating box 53, and the tooth plate 532 is meshed with the transmission gear 534.

[0076] A transmission tube 531 is provided in the middle of the transmission gear 534, one end of the transmission tube 531 is exposed outside the grease box 53, the grease nozzle 51 is provided on the transmission tube 531, and the transmission tube 531 is externally connected to the grease supply system 1; the grease nozzle 51 is also provided with a sensor 52, and the sensor 52 is fixed on the transmission tube 531.

[0077] Specifically, the linear drive structure 533 inside the grease box 53 uses a high-precision electric push rod with a stroke of 50 cm and a thrust of up to 200N, which can accurately push the tooth plate 532 to move. The linear drive structure 533 can also use a cylinder. The tooth plate 532 and the transmission gear 534 are made of high-strength alloy steel, which are precision machined and heat-treated to ensure high meshing accuracy and durability. A transmission pipe 531 is installed in the middle of the transmission gear 534. The transmission pipe 531 is made of stainless steel with an inner diameter of 4 mm, which can ensure smooth transmission of grease. The grease nozzle 51 needs to ensure that the grease can be evenly sprayed.

[0078] When the air guide plate reaches the greasing station, the greasing structures 5 on both sides are started simultaneously under the command of the central control system. First, the greasing box 53, driven by the second slider, moves to a suitable position on the second guide rail 535 according to the structure of the air guide plate and the greasing position requirements. Ensure that after the fixture 3 clamps the air guide plate, the greasing nozzle 51 can be aligned with the connecting shaft of the air guide plate to ensure normal greasing. During the greasing process, the linear drive structure 533 pushes the tooth plate 532 to move, and the tooth plate 532 drives the transmission gear 534 to rotate, thereby rotating the transmission pipe 531 and the greasing nozzle 51; and the grease supply system 1, under the action of the pressure controller 12, delivers the lubricating grease to the greasing nozzle 51 through the transmission pipe 531 at a stable pressure and flow rate, and can also spray the lubricating grease on the surface of the connecting shaft of the air guide plate by controlling the greasing parameters, such as the injection time, the injection amount, etc. During the greasing process, the visual inspection system 4 continuously monitors the greasing situation, and immediately feeds back to the central control system if problems such as uneven greasing, grease accumulation or missing greasing are found. The central control system will adjust the grease coating parameters in time, such as changing the angle of the grease coating nozzle 51, increasing or decreasing the grease spraying amount, etc., or suspending the grease coating operation for correction.

[0079] In this embodiment, a recovery box 54 is disposed below the transmission pipe 531 , and the recovery box 54 is connected to the grease supply device 13 .

[0080] In the actual greasing production process, when the device starts to operate, the lubricating grease reaches the greasing nozzle 51 through the grease supply device 13 and the transmission pipe 531 to grease the workpiece. Since the grease may be over-sprayed or the grease may slide due to the surface structure of the workpiece during the greasing process, the recovery box 54 can recover the excess or slipped grease.

[0081] The recovery box 54 is placed in a position where dripping grease can be effectively collected. More preferably, the positive projection of the transmission tube 531 in the recovery box 54 should be located inside the recovery box 54 to ensure that the lubricating grease that overflows from around the transmission tube 531 and during the greasing process can be caught to the greatest extent. Since the recovery box 54 is connected to the grease supply device 13, the recovered lubricating grease can be transported back to the grease supply device 13 through a specially designed pipeline and pump system (for example, a corrosion-resistant hose connection and a small gear pump for grease delivery). A filtering and purification device is provided in the grease supply device 13. When the recovered grease re-enters, it will be filtered to remove impurities that may be mixed in it, such as tiny metal debris and dust on the surface of the workpiece, and then it will be purified to adjust its viscosity and performance parameters so that it can meet the quality requirements of grease application again.

[0082] Example 5

[0083] See also Figure 1-Figure 6 , this embodiment provides a workpiece greasing method, which is implemented based on the automatic greasing device as described above.

[0084] The method works as follows:

[0085] Place the air guide plate to be greased at the starting end of the conveyor line and start the device. The air guide plate moves along the conveyor line to the bottom of the visual inspection system 4, which quickly collects image information of the air guide plate and transmits it to the control system of the device.

[0086] According to the visual inspection results, the fixture 3 of the grease coating station starts working and firmly clamps the air guide plate. The grease coating structures 5 on both sides are driven by the control system to move to the appropriate position and adjust the angle of the grease coating nozzle 51. Grease is sprayed on the connecting shaft of the air guide plate.

[0087] During the greasing process, the greasing nozzle 51 rotates to spray different positions of the connecting shaft. In addition, the recovery box 54 below the transmission pipe 531 collects the excess grease generated by the greasing operation in real time, and the recovered grease is transported back to the grease supply device 13 through the connecting pipeline for filtration and reuse.

[0088] After greasing is completed, the visual inspection system 4 will inspect the bearing greasing again to check whether the greasing is uniform and whether there are any areas of missed greasing. If the greasing quality is qualified, the fixture 3 releases the air guide plate, and the greased air guide plate leaves the greasing station under the conveyor line and enters the subsequent assembly process; if a greasing quality problem is detected, the system will sound an alarm and send the air guide plate back to the greasing station for re-greasing or manual intervention.

[0089] In addition, it should be noted that the technology of the present application for re-detecting the bearing grease condition through the visual inspection system 4, the visual judgment algorithm therein is not the protection point of the present application, so the process of visual inspection and judgment is described in detail.

[0090] 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 present application.
