[0059] The inventors discovered that manual grease application cannot guarantee the proper amount of grease applied, and the application is uneven, easily contaminating foreign matter, causing cylinder malfunction and shortening the cylinder's service life. Furthermore, manual grease application is inefficient, resulting in higher product costs.

[0060] Based on this, the present invention provides a digital quantitative oiling machine, which is described in detail below through specific embodiments.

[0061] The utility model provides a digital quantitative oiling machine, which is characterized in that Figure 1 As shown, it includes a control component and an execution component;

[0062] The control assembly includes a controller, a barcode scanner (not shown) and a solenoid valve assembly 8;

[0063] The actuator assembly includes an air intake mechanism 7, an oil storage cylinder 12, a booster cylinder 15, an oil outlet nozzle 16 and an oil mist spray gun 22;

[0064] The air intake mechanism 7 is connected to the solenoid valve group 8 and can be connected to an external compressed air source; the solenoid valve group 8 is respectively connected to the oil storage cylinder 12, the boost cylinder 15 and the oil mist spray gun 22;

[0065] The oil storage cylinder 12, the boost cylinder 15, the oil outlet nozzle 16 and the oil mist spray gun 22 are connected in sequence by pipelines;

[0066] The controller is respectively connected to the barcode scanner and the solenoid valve group 8 by signals;

[0067] The barcode scanner can scan the electronic tag of the workpiece to identify the model of the workpiece;

[0068] The controller can control the operation of the oil storage cylinder 12 , the boost cylinder 15 and the oil mist spray gun 22 by controlling the opening and closing of the solenoid valve group 8 , and can control the oil output of the oil mist spray gun 22 by controlling the opening time of the solenoid valve group 8 .

[0069] The digital quantitative oiling machine provided by the embodiment of the present invention can be used in conjunction with a workpiece production system (e.g., a cylinder parts production system). Specifically, the digital quantitative oiling machine can be placed at a preset position on the conveyor of the workpiece production system. When the finished workpiece is conveyed to the preset position, the digital quantitative oiling machine uses its barcode scanner to scan the electronic tag corresponding to the workpiece to identify the model of the workpiece and send the workpiece model information to the controller. The controller controls the opening and closing of different passages in the solenoid valve group 8 and the opening time according to the workpiece model, thereby controlling the oil mist spray gun 22 to spray the oil output corresponding to the workpiece model.

[0070] In the present utility model embodiment, refer to Figure 1As shown, the solenoid valve group 8 is respectively connected to the oil storage cylinder 12, the boost cylinder 15 and the oil mist spray gun 22. The compressed air from the air intake mechanism 7 can be injected into the oil storage cylinder 12, the boost cylinder 15 and the oil mist spray gun 22 respectively, so that the grease in the oil storage cylinder 12 is transported to the boost cylinder 15, and after the grease is pressurized for the second time in the boost cylinder 15, it enters the oil mist spray gun 22 and mixes with the compressed air to spray out oil mist.

[0071] Specifically, refer to Figure 1 and Figure 2 As shown, the solenoid valve assembly 8 includes a first solenoid valve 81, a second solenoid valve 82, a third solenoid valve 83, and a fourth solenoid valve 84. A controller can control the opening and closing, as well as the opening timing, of each of the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83, and the fourth solenoid valve 84. The exhaust port of the first solenoid valve 81 is connected to the oil reservoir 12. When the controller controls the opening of the first air inlet of the first solenoid valve 81, compressed air is introduced into the oil reservoir 12, pushing the piston within the oil reservoir 12, thereby squeezing the oil chamber of the oil reservoir 12 and propelling the grease within the chamber toward the booster cylinder 15. The first air inlet and the second air inlet of the second solenoid valve 82 are respectively connected to the boosting cylinder 15. When the controller controls the first air inlet of the second solenoid valve 82 to open, compressed air is input into the boosting cylinder 15 and pushes the piston in the boosting cylinder 15 to move forward, thereby squeezing the boosting chamber of the boosting cylinder 15, and the grease in the boosting chamber is pressurized for the second time and then pushed toward the oil mist spray gun 22; when the controller controls the second air inlet of the second solenoid valve 82 to open, compressed air is input into the boosting cylinder 15 and pushes the piston in the boosting cylinder 15 to move in the opposite direction until it returns to its original position, thereby releasing the squeezing of the boosting chamber and, at the same time, preparing for the next secondary pressurization. The oil mist spray gun 22 includes an oil spray mechanism, an air jet mechanism and a mixing chamber. The air inlet of the third solenoid valve 83 is connected to the oil spray mechanism of the oil mist spray gun 22, and the air inlet of the fourth solenoid valve 84 is connected to the air jet mechanism of the oil mist spray gun 22. When the controller controls the air inlet of the third solenoid valve 83 to open, compressed air enters the oil spray mechanism of the oil mist spray gun 22 to pressurize the grease in the oil spray mechanism again and then push it into the mixing chamber. When the controller controls the air inlet of the fourth solenoid valve 84 to open, compressed air enters the mixing chamber through the air jet mechanism and mixes with the grease to form oil mist and then sprayed out.

[0072] In this embodiment of the present invention, the oil spraying speed of the oil mist spray gun 22 can be pre-adjusted to a preset speed value. During operation of the digital quantitative oiler, the oil spraying speed of the oil mist spray gun 22 is fixed. Therefore, the oil output of the oil mist spray gun 22 can be controlled by controlling the opening time of the air inlets of the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83, and the fourth solenoid valve 84.

[0073] The digital quantitative oiling machine provided by the embodiment of the present utility model identifies the model of the workpiece through a barcode scanning gun and feeds back the workpiece model to the controller. The controller can control the opening and closing and opening time of the solenoid valve according to the model of each workpiece, thereby injecting compressed air into the oil storage cylinder 12, the booster cylinder 15 and the oil mist spray gun 22 as needed, thereby controlling the oil mist spraying amount of the oil mist spray gun 22 according to the model of the workpiece, and then realizing quantitative oil spraying of the workpiece, so that the grease can be quickly, accurately and evenly covered on the surface of the cylinder parts, thereby achieving full lubrication of the workpiece, effectively improving the oiling efficiency and saving labor costs.

[0074] The digital quantitative oiler provided by the embodiment of the utility model inputs compressed air into the oil storage cylinder 12, the booster cylinder 15 and the oil mist spray gun 22 respectively, ensures the smooth spraying of grease by secondary boosting, mixes the grease and compressed air through the oil mist spray gun 22, and atomizes the grease, so that the grease can be evenly sprayed on the surface of the workpiece, thereby improving the uniformity of oiling and reducing grease loss.

[0075] In an alternative embodiment, reference Figure 1 and Figure 2 As shown, the control component further comprises a display 11 connected to the controller signal. The display 11 comprises a display screen and a buzzer alarm 27 arranged below the display screen, the buzzer alarm 27 is used to sound an alarm, and the display screen is used to display alarm information related to the alarm.

[0076] In an alternative embodiment, reference Figure 1 As shown, the control assembly also includes a magnetic switch 23 connected to the controller signal. The piston of the oil storage cylinder 12 is provided with a magnet. The magnetic switch 23 is located on the side of the oil storage cylinder 12 to monitor the oil level in the oil storage cylinder 12 by monitoring the position of the piston in the oil storage cylinder 12. The magnetic switch 23 can send the oil level monitoring results to the controller. When the oil level is low, the controller controls the buzzer alarm 27 to sound an alarm and controls the display screen to display an alarm message indicating low oil level.

[0077] The digital quantitative oiling machine provided by the embodiment of the present invention monitors the remaining oil amount in the oil storage cylinder 12 in real time through the magnetic switch 23, and can be informed of the insufficient oil amount in the oil storage cylinder 12 in real time, so that the oil amount in the oil storage cylinder 12 can be replenished in time, effectively preventing sudden interruption of oil injection, speeding up the production rhythm, and improving the workpiece oiling and assembly efficiency.

[0078] In an alternative embodiment, reference Figure 1 and Figure 2As shown, the actuator assembly also includes an oil filling port 14 and an on-off valve 20. The oil filling port 14 is provided on the pipeline between the oil storage cylinder 12 and the boost cylinder 15, and is connected to the oil storage cylinder 12, and is used for an external oil filling mechanism to replenish grease into the oil storage cylinder 12. The oil filling mechanism may include an oil pump and an oil storage container, and the oil pump is connected to the oil filling port 14 and the oil storage container respectively, and can pump the grease in the oil storage container into the oil storage cylinder 12. The oil pump is also powered by an external compressed air source. Therefore, the second air inlet of the first solenoid valve 81 is connected to the oil pump, and the second air inlet of the first solenoid valve 81 can be controlled by the controller to open, thereby driving the oil pump to pump the grease in the oil storage container into the oil storage cylinder 12.

[0079] In an alternative embodiment, reference Figure 1 and Figure 2 As shown, the display 11 also includes a refueling button (not shown) disposed below the display screen. When the buzzer alarm 27 sounds and the display screen displays an alarm message indicating insufficient oil, it indicates that grease needs to be added to the oil storage cylinder 12. At this time, the refueling button can be pressed to cause the display 11 to send a message indicating the need for refueling to the controller. After receiving the message, the controller controls the first air inlet of the first solenoid valve 81, the first and second air inlets of the second solenoid valve 82, the air inlet of the third solenoid valve 83, and the air inlet of the fourth solenoid valve 84 to close, thereby stopping the lubrication operation. It also controls the second air inlet of the first solenoid valve 81 to open, driving the oil pump to pump the grease in the oil storage container into the oil storage cylinder 12. When the magnetic switch 23 detects that the oil level in the oil storage cylinder 12 has reached the preset capacity, the controller controls the second air inlet of the first solenoid valve 81 to close, stopping the oil filling.

[0080] Further, refer to Figure 1 As shown, the on-off valve 20 is arranged on the pipeline between the oil filling port 14 and the boosting cylinder 15, and is used to control the on-off of the pipeline between the oil filling port 14 and the boosting cylinder 15. When the digital quantitative oiler is performing the oiling operation, the on-off valve 20 needs to remain in the open state so that the grease in the oil storage cylinder 12 can smoothly enter the boosting cylinder 15; when grease is replenished into the oil storage cylinder 12, the on-off valve 20 needs to remain in the closed state to prevent the replenished grease from being directly injected into the boosting cylinder 15.

[0081] In an alternative embodiment, reference Figure 1As shown, the control component also includes a photoelectric sensor 19 connected to the controller signal. The photoelectric sensor 19 is arranged on the side of the on-off valve 20 and is used to monitor the on-off state of the on-off valve 20. In addition, the photoelectric sensor 19 can send the on-off state monitoring result to the controller; the controller can control the buzzer alarm 27 to sound an alarm based on the on-off state monitoring result, and control the display screen to display an alarm message. Specifically, when the digital quantitative oiler is in the working state, if the photoelectric sensor 19 detects that the on-off valve 20 is in the closed state, the buzzer alarm 27 will sound an alarm, and the display screen will display an alarm message indicating that the on-off valve 20 is in the closed state; when grease is added to the oil storage cylinder 12, if the photoelectric sensor 19 detects that the on-off valve 20 is in the open state, the buzzer alarm 27 will sound an alarm, and the display screen will display an alarm message indicating that the on-off valve 20 is in the open state.

[0082] In an alternative embodiment, reference Figure 1 As shown, the display 11 further includes a power OFF button 25, a power ON button 26, and a three-position selector switch 24 disposed below the display screen. The power OFF button 25 is used to turn off the power of the digital quantitative oiler, and the power ON button 26 is used to turn on the power of the digital quantitative oiler. The three-position selector switch 24 is used to control the digital quantitative oiler to start, stop, or enter an inspection state.

[0083] In an alternative embodiment, reference Figure 1 As shown, the actuator assembly further includes a one-way valve 21 disposed between the oil reservoir 12 and the booster cylinder 15. The inlet of the one-way valve 21 faces the oil reservoir 12, and the outlet faces the booster cylinder 15. This prevents grease from flowing back from the booster cylinder 15 to the oil reservoir 12 during the lubrication operation, thereby improving operational safety and efficiency. Optionally, the one-way valve 21 can be disposed between the on-off valve 20 and the booster cylinder 15.

[0084] In an alternative embodiment, reference Figure 1As shown, the control assembly also includes a first pressure sensor 13 and a second pressure sensor 17, which are connected to the controller signal. The first pressure sensor 13 is located between the oil reservoir 12 and the boost cylinder 15 and is used to monitor the pressure in the pipeline between the oil reservoir 12 and the boost cylinder 15. The second pressure sensor 17 is located between the boost cylinder 15 and the oil outlet nozzle 16 and is used to monitor the pressure in the pipeline between the boost cylinder 15 and the oil outlet nozzle 16. The first and second pressure sensors 13 and 17 can transmit pressure monitoring results to the controller, which can control the buzzer alarm 27 to sound an alarm based on the pressure monitoring results and control the display screen to display an alarm message. Specifically, when the first pressure sensor 13 detects an abnormal pressure in the pipeline between the oil reservoir 12 and the boost cylinder 15 and / or the second pressure sensor 17 detects an abnormal pressure in the pipeline between the boost cylinder 15 and the oil outlet nozzle 16, the controller controls the buzzer alarm 27 to sound an alarm and controls the display screen to display an alarm message indicating the pressure abnormality.

[0085] In an alternative embodiment, reference Figure 1 As shown, the actuator assembly further includes an exhaust valve 18, which is disposed on the pipeline between the boost cylinder 15 and the oil outlet nozzle 16. When the second pressure sensor 17 detects that the pipeline pressure between the boost cylinder 15 and the oil outlet nozzle 16 is lower than normal, it indicates that air may have entered the pipeline between the boost cylinder 15 and the oil outlet nozzle 16. In this case, you can try to open the exhaust valve 18 to exhaust the air in the pipeline.

[0086] In an alternative embodiment, reference Figure 1 As shown, the controller includes an electric control box 2 and a PLC3, a relay 5 and a terminal block 4 contained in the electric control box 2. The signal output end of the PLC3 is connected to the relay 5 through the terminal block 4, and the relay 5 is respectively connected to the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83 and the fourth solenoid valve 84. A control signal is sent to the relay 5 through the PLC3 to control the relay 5 to be connected or disconnected. When a certain relay 5 is controlled to be connected, the corresponding solenoid valve is opened, and when the relay 5 is controlled to be disconnected, the corresponding solenoid valve is closed. The signal output ends of the magnetic switch 23, the photoelectric sensor 19, the first pressure sensor 13, the second pressure sensor 17, and the barcode scanner are connected to the signal input end of the PLC3 so that the PLC3 receives relevant monitoring information. The signal output end of the display screen is connected to the signal input end of the PLC3, and the signal input end of the display screen is connected to the signal output end of the PLC3 to realize information transmission between the display screen and the PLC3.

[0087] In an alternative embodiment, reference Figure 1 and Figure 2As shown, the air intake mechanism 7 includes an air source switch 71 and a pressure reducing valve 72 connected thereto. The pressure reducing valve 72 is connected to the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83, and the fourth solenoid valve 84. The air source switch 71 can be connected to a compressed air source, and the pressure reducing valve 72 is used to adjust the pressure of the compressed air.

[0089] In an alternative embodiment, reference Figure 1 As shown, the digital quantitative oiling machine also includes a main frame 10. The main frame 10 includes a top plate 101 and a frame 102 for supporting the top plate 101, and the frame 102 is a cubic frame structure as a whole, and an open receiving portion 103 is formed between the top plate 101 and the frame 102. The controller is installed in the receiving portion 103 of the main frame 10. The bottom of the oil storage cylinder 12 and the boosting cylinder 15 are fixed to the bottom plate 104. Accordingly, the pipelines, opening and closing valves 20, oil outlet nozzles 16 and other components around the oil storage cylinder 12 and the boosting cylinder 15 are all located above the bottom plate 104. The bottom of the photoelectric sensor 19 is fixed to the bottom plate 104, and the bottom surface of the bottom plate 104 is fixedly mounted on the bottom surface of the frame 102 of the main frame 10. In addition, the display 11 is arranged on the upper surface of the top plate 101, and the display 11 is raised and fixed above the top plate 101 by a support column 106, which is convenient for the staff to view or operate the display 11.

[0090] In an alternative embodiment, reference Figure 1 As shown, the air intake mechanism 7 and solenoid valve assembly 8 are installed within the housing 103 of the main frame 10. An air control cabinet door 6 is provided on the side of the main frame 10 near the air intake mechanism 7. The air intake of the air intake mechanism 7 extends out of the air control cabinet door 6, facilitating connection to an external compressed air source. An electrical control cabinet door 1 is also provided on the side of the main frame 10 near the controller. Both the air control cabinet door 6 and the electrical control cabinet door 1 are located on the side of the frame 102 facing the display screen.
