Description
Technical Field
[0001] The invention relates to the technical field of grease guns, in particular to a control method for a high-pressure quantitative oil-discharging grease gun and a high-pressure quantitative oil-discharging grease gun. Background Art
[0002] In order to ensure stable and efficient operation of the equipment, it is very important to regularly maintain the equipment through a grease gun. The existing technology mainly realizes electric refueling by driving the plunger of the plunger pump to move the piston through the transmission mechanism of the motor. For example, an electric grease gun with patent publication number CN213207222U includes a grease gun housing, a confluence seat and a grease barrel are arranged in the grease gun housing, the confluence seat is arranged at the front end of the grease barrel, a push rod is arranged in the grease barrel, and a spring is installed on the push rod. The grease gun housing is provided with a motor, and the confluence seat is provided with a plunger. The motor drives the eccentric wheel to rotate and drives the plunger through the eccentric wheel. A piston moves in the busbar, and a hand-held portion is provided on the grease gun housing, on which a start switch is placed, and a first battery pack slot is provided at the rear of the hand-held portion, on which a first battery pack is detachably provided, and a second battery pack slot is also provided on the grease gun housing, and a sealing plate is provided on the outer cover of the second battery pack slot. After the sealing plate is removed, the second battery pack can be placed on the second battery pack slot. The amount of butter pumped in the above scheme is determined by the piston stroke, but there is no stroke acquisition mechanism in the above scheme. Therefore, it can be seen that how to accurately control the amount of butter filling is a technical problem that needs to be urgently solved in the prior art. Summary of the invention
[0003] In view of the technical problem that the prior art is difficult to accurately control the butter filling amount, the present invention provides a high-pressure quantitative oil-discharging grease gun control method and a high-pressure quantitative oil-discharging grease gun. The counting times of the Hall sensor are obtained through the user's preset information, and the user's filling amount requirements are converted into quantifiable digital control instructions, namely the counting times of the Hall sensor, thereby eliminating the errors caused by traditional mechanical filling. The magnet trigger pulse signal of the Hall sensor is further detected to achieve accurate tracking of the crankshaft stroke. When it is detected once, it means that the crankshaft reaches the maximum movement stroke once, that is, the filling is completed once, and the counting times are reduced at the same time. When the reduced counting times do not meet the conditions, the magnet trigger pulse signal is continued to be detected until the conditions are met. When the conditions are met, it means that the refueling is completed. The technical problem that the prior art is difficult to accurately control the butter filling amount is solved, and the accuracy and automation of the butter filling amount are significantly improved.
[0004] In order to solve the above technical problems, the present invention provides a high-pressure quantitative oil-discharging grease gun control method, comprising the following steps: S1: Obtain the preset information of the user, obtain the number of counts of the Hall sensor according to the preset information, and drive the brushless motor; S2: Obtain the driving signal output by the brushless motor and drive the crank lever to move through the driving signal; S3: During the process of driving the crank lever to move through the driving signal, determine whether the magnet trigger pulse signal of the Hall sensor is detected. If it is obtained, reduce the counting times, and determine whether the reduced counting times meet the conditions. If they meet, it means that the refueling is completed. If they do not meet, execute S2 again.
[0005] After adopting the above technical solution, the present invention has the following advantages: Obtain the counting times of the Hall sensor through the preset information of the user, convert the refueling amount requirement of the user into a quantifiable digital control instruction, that is, the counting times of the Hall sensor, eliminate the error caused by traditional mechanical refueling, further detect the magnet trigger pulse signal of the Hall sensor, and realize the accurate tracking of the crank lever stroke. When a detection is made once, it means that the crank lever reaches the maximum movement stroke once, that is, the refueling is completed once, and at the same time the counting times are reduced. When the reduced counting times do not meet the conditions, continue to detect the magnet trigger pulse signal until the conditions are met. When the conditions are met, it means that the refueling is completed. Solve the technical problem that it is difficult to accurately control the butter refueling amount in the prior art, significantly improve the accuracy and automation degree of the butter refueling amount, avoid waste of resources, and at the same time reduce the wear risk of the equipment caused by insufficient lubrication; Since the brushless motor has the advantages of high speed and large pressure, the method of driving the crank lever to move through the brushless motor significantly improves the refueling speed.
[0006] Preferably, in S1, before obtaining the counting times of the Hall sensor according to the preset information, it further includes: S11: Determine whether the preset information is trigger switch information or standby switch information. When it is determined to be trigger switch information, continue to determine whether abnormal monitoring information is received; S12: If abnormal monitoring information is received, control the LED to flash a preset number of times and then power off. If abnormal monitoring information is not received, obtain the counting times of the Hall sensor according to the preset information; S13: When it is determined to be standby switch information, continue to determine whether trigger switch information is received within the first preset time. If trigger switch information is received within the first preset time, continue to determine whether abnormal monitoring information is received, and execute S12. If trigger switch information is not received within the first preset time, power off.
[0007] In this solution, when the high-pressure quantitative oil outlet grease gun starts to inject oil, it first determines whether the user's operation is a valid operation. When it is a valid operation, that is, when the trigger switch information is obtained, it first performs an abnormality detection. When the abnormality detection passes, it continues with the subsequent operations, thereby improving the safety of the high-pressure quantitative oil outlet grease gun during use. When the standby switch information is obtained, the high-pressure quantitative oil outlet grease gun starts a countdown. When the trigger switch information and the standby switch information are not received by the end time, the power is automatically cut off, thereby avoiding the waste of battery power caused by neglect. When the standby switch information is received by the end time, the countdown is continued, and the above steps are repeated, so that when the trigger switch information is obtained subsequently, there is no need to perform initialization again, thereby improving the working efficiency of the high-pressure quantitative oil outlet grease gun.
[0008] Preferably, in S13, if the trigger switch information is not received within the first preset time and the power is cut off, it further includes: if the trigger switch information is not received within the first preset time, it continues to determine whether the trigger switch information is received within the second preset time. If the trigger switch information is received within the second preset time, it continues to determine whether the abnormality monitoring information is received, and executes S12. If the trigger switch information is not received within the second preset time, the power is cut off.
[0009] Preferably, in S12, the abnormality monitoring information is any one of communication abnormality monitoring information, temperature abnormality monitoring information, and voltage abnormality communication information.
[0010] Preferably, the S2 further includes: During the process of driving the crank by the driving signal, the working electrical signal of the brushless motor is obtained. When the working electrical signal is greater than the preset electrical signal, the corresponding protection action is triggered and the power is cut off, otherwise S3 is executed.
[0011] Preferably, the protection actions include overcurrent protection and high-voltage protection.
[0012] The beneficial effects of this solution: Obtain the counting times of the Hall sensor through the preset information of the user, convert the user's filling volume requirement into a quantifiable digital control instruction, i.e., the counting times of the Hall sensor, eliminate the errors caused by traditional mechanical filling, further detect the magnet trigger pulse signal of the Hall sensor, and achieve precise tracking of the crank lever stroke. When a detection is made once, it means that the crank lever reaches the maximum movement stroke once, that is, one filling is completed, and at the same time the counting times decrease. When the decreased counting times do not meet the conditions, continue to detect the magnet trigger pulse signal until the conditions are met. When the conditions are met, it means that the refueling is completed. This solves the technical problem that it is difficult to accurately control the butter filling volume in the prior art, significantly improves the accuracy and automation degree of the butter filling volume, avoids resource waste, and reduces the wear risk of the equipment caused by insufficient lubrication; Since the brushless motor has the advantages of high speed and large pressure, the method of driving the crank lever by the brushless motor significantly improves the refueling speed; When the high-pressure quantitative oil output grease gun starts to inject oil, it first performs abnormal detection. When the abnormal detection passes, it continues with the subsequent operations, thereby improving the safety of the high-pressure quantitative oil output grease gun during use; When the standby switch information is obtained, the high-pressure quantitative oil output grease gun starts a countdown. When the trigger switch information and the standby switch information are not received at the end time, the power is automatically cut off, thereby avoiding the waste of battery power caused by neglect. When the standby switch information is received at the end time, continue to start the countdown and repeat the above steps, so that when the trigger switch information is obtained subsequently, there is no need to initialize again, thereby improving the working efficiency of the high-pressure quantitative oil output grease gun.
[0013] The present invention also provides a high-pressure quantitative oil output grease gun applicable to the control method of the high-pressure quantitative oil output grease gun, which at least includes a control module, a motor drive module and a Hall counting module, and the control module is respectively communicatively connected to the motor drive module and the Hall counting module.

The base of the transistor Q1 is grounded through the resistor R3, and the base of the transistor Q1 is also connected to the resistor R2.
[0017] Advantages of this solution: The counting times of the Hall sensor are obtained through the Hall counting module, and the user's filling volume requirement is converted into a quantifiable digital control instruction, that is, the counting times of the Hall sensor, eliminating the error caused by traditional mechanical filling. Further, by detecting the magnet trigger pulse signal of the Hall sensor, the precise tracking of the crank lever stroke is realized, solving the technical problem that it is difficult to accurately control the butter filling volume in the prior art, significantly improving the accuracy and automation degree of the butter filling volume, avoiding resource waste, and reducing the wear risk of the equipment caused by insufficient lubrication at the same time; Through the flashing times of the white light diode WLED in the LED module, different fault information can be intuitively obtained, improving the safety and the maintenance efficiency of the maintenance personnel at the same time.

The drawings are only for the purpose of showing the preferred embodiments and are not considered as a limitation of the present invention. Moreover, throughout the drawings, the same reference signs are used to represent the same components.

Detailed Embodiments
[0020] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only the best embodiments of the present invention, only used to explain the present invention, and do not limit the protection scope of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
[0021] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of the operations (or steps) can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operations are completed, but it can also have additional steps not included in the drawings; the process can correspond to a method, function, procedure, subroutine, subprogram, etc.
[0022] Embodiment 1: As Figure 1 shown, a high-pressure quantitative oil outlet grease gun control method includes the following steps: S1: Obtain the preset information of the user, obtain the counting times of the Hall sensor according to the preset information, and drive the brushless motor.
[0023] In this embodiment, the preset information of the user includes trigger switch information and standby switch information. When the user presses the corresponding gear, the trigger switch information is obtained. In this embodiment, the gear is specifically the 10th gear. At the same time, the Hall sensor counts once, indicating that the injected grease is 0.6 grams. Therefore, obtaining the counting times of the Hall sensor through the preset information is essentially to obtain the amount of grease to be injected. For example, when the counting times of the Hall sensor is 2, the amount of grease to be injected at this time is 1.2 grams. By converting the user's filling amount requirement into a quantifiable digital control instruction, that is, the counting times of the Hall sensor, the error caused by traditional mechanical filling is eliminated.
[0024] As a preferred embodiment, in S1, before obtaining the counting times of the Hall sensor according to the preset information, it further includes: S11: Determine whether the preset information is trigger switch information or standby switch information. When it is determined to be trigger switch information, then continue to determine whether abnormal monitoring information is received; S12: If abnormal monitoring information is received, control the LED to flash a preset number of times and then power off. If abnormal monitoring information is not received, obtain the counting times of the Hall sensor according to the preset information; S13: When it is determined to be standby switch information, then continue to determine whether trigger switch information is received within the first preset time. If trigger switch information is received within the first preset time, then continue to determine whether abnormal monitoring information is received, and execute S12. If trigger switch information is not received within the first preset time, then power off.
[0025] In this embodiment, the preset number of times is set according to the abnormal monitoring information. Different abnormal monitoring information corresponds to different preset numbers of times. When the abnormal monitoring information is received and the number of times the LED flashes reaches the preset number of times, after 10 seconds, the high-pressure metering oil output grease gun is controlled to power off, thereby ensuring the safety of the high-pressure metering oil output grease gun during use. The first preset time is 10s. When the standby switch information is obtained, the high-pressure metering oil output grease gun starts to standby, and at the same time the LED continuously lights for 10s. During the 10s when the LED continuously lights, if the trigger switch information and the standby switch information are not received, that is, no button is pressed, the power is automatically cut off, thereby avoiding the waste of battery power caused by neglect. If the standby switch information is received, the high-pressure metering oil output grease gun continues to standby, and at the same time the LED continues to continuously light for 10s. Repeat the above operation, so that when the trigger switch information is obtained subsequently, there is no need to initialize again, thereby improving the working efficiency of the high-pressure metering oil output grease gun. If the trigger switch information is received, it is continued to determine whether the abnormal monitoring information is received. When the abnormal monitoring information is received, the LED is controlled to flash a preset number of times and then power off. If the abnormal monitoring information is not received, the counting number of times of the Hall sensor is obtained according to the preset information.
[0026] As a preferred embodiment, in S13, the step of powering off if the trigger switch information is not received within the first preset time further includes: If the trigger switch information is not received within the first preset time, it is continued to determine whether the trigger switch information is received within the second preset time. If the trigger switch information is received within the second preset time, it is continued to determine whether the abnormal monitoring information is received, and S12 is executed. If the trigger switch information is not received within the second preset time, the power is cut off.
[0027] In this embodiment, the second preset time is specifically 60 s. If the trigger switch information is not received within the second preset time, power is cut off. Specifically: if the trigger switch information is not received within the second preset time, it is judged whether the standby switch information is received. If not, power is cut off. If the standby switch information is received, the high-pressure quantitative oil output grease gun starts to standby, and at the same time the LED continuously lights for 10 s. During the 10 s when the LED continuously lights, if the trigger switch information and the standby switch information are not received, that is, no button is pressed, power is automatically cut off, thus avoiding the waste of battery power caused by neglect. If the standby switch information is received, the high-pressure quantitative oil output grease gun continues to standby, and at the same time the LED continues to continuously light for 10 s. Repeat the above operation, so that when the trigger switch information is obtained subsequently, there is no need to initialize again, thereby improving the working efficiency of the high-pressure quantitative oil output grease gun. If the trigger switch information is received, it is continued to judge whether the abnormal monitoring information is received. When the abnormal monitoring information is received, the LED is controlled to flash a preset number of times and then power is cut off. If the abnormal monitoring information is not received, the counting times of the Hall sensor are obtained according to the preset information.
[0028] Specifically, in S12, the abnormal monitoring information is any one of communication abnormal monitoring information, temperature abnormal monitoring information, and voltage abnormal communication information.
[0029] S2: Obtain the driving signal output by the brushless motor, and drive the crank rod to move through the driving signal.
[0030] As a preferred embodiment, S2 further includes: During the process of driving the crank rod to move through the driving signal, obtain the working electrical signal of the brushless motor. When the working electrical signal is greater than the preset electrical signal, trigger the corresponding protection action and cut off the power, otherwise execute S3.
[0031] In this embodiment, the working electrical signal of the brushless motor is specifically the working current of the brushless motor. In this embodiment, the working current is detected by the detected current on the PCB. In this embodiment, the load force of the brushless motor is characterized by obtaining the working current. Therefore, when the working electrical signal is greater than the preset electrical signal, it indicates that the load of the brushless motor is too large. For the sake of safety, the protection is triggered and the power is cut off. The preset electrical signal is specifically the preset current, and the preset current is set according to the maximum current acceptable by the brushless motor.
[0032] Specifically, the protection actions include overcurrent protection and high-voltage protection.
[0033] In this embodiment, the protection actions further include short-circuit protection, low-voltage protection, temperature protection, open-phase protection, and communication protection. When a protection action is triggered, the brushless motor stops working, and at the same time, the PCB stands by for 10 s. During the 10 s when the PCB stands by, the LED on the PCB blinks. Specifically, when it is short-circuit protection, it blinks once; when it is the first-level overcurrent protection in overcurrent protection, it blinks twice; when it is the second-level overcurrent protection in overcurrent protection, it blinks three times; when it is the third-level overcurrent protection in overcurrent protection, it blinks four times; when it is high-voltage protection, it blinks five times; when it is low-voltage protection, it blinks six times; when it is temperature protection, it blinks seven times; when it is open-phase protection, it blinks eight times; when it is communication protection, it blinks nine times. Different protection actions are set with different blinking times, enabling the operator to judge the specific fault according to the blinking times, thereby improving the maintenance efficiency.
[0034] S3: During the process of driving the crank by the driving signal, it is judged whether the magnet trigger pulse signal of the Hall sensor is detected. If it is obtained, the counting times are reduced, and it is judged whether the reduced counting times meet the conditions. If they meet, it means that the refueling is completed. If they do not meet, S2 is executed again.
[0035] In this embodiment, the Hall sensor is arranged at the front end or the rear end of the high-pressure quantitative oil outlet grease gun. Specifically, the front end is the position where the bottom of the crank is located when the crank reaches the maximum extension degree, and the rear end is the position where the top of the crank is located when the crank rebounds after reaching the maximum extension degree. When the magnet trigger pulse signal is obtained, the counting times are decreased by one. When the counting times are equal to 0, it means that the conditions are met; otherwise, it means that the conditions are not met. This solves the technical problem in the prior art that it is difficult to accurately control the grease filling amount, significantly improves the accuracy and automation degree of the grease filling amount, avoids waste of resources, and reduces the wear risk of the equipment caused by insufficient lubrication at the same time.
[0036] Embodiment 2: As Figure 2 shown, this embodiment further provides a high-pressure quantitative oil outlet grease gun applicable to the control method of the high-pressure quantitative oil outlet grease gun, which at least includes a control module, a motor drive module, and a Hall counting module. The control module is communicatively connected to the motor drive module and the Hall counting module respectively.
[0037] In this embodiment, the control module is specifically a microcontroller chip. The motor drive module includes a motor drive power circuit, a drive current amplification and conditioning circuit, a motor back electromotive force conditioning circuit, and a brushless motor. The motor drive power circuit, the drive current amplification and conditioning circuit, and the motor back electromotive force conditioning circuit are all communicatively connected to the microcontroller chip. The motor drive power circuit is electrically connected to the drive current amplification and conditioning circuit, and the brushless motor is electrically connected to the motor drive power circuit and the motor back electromotive force conditioning circuit respectively. The brushless motor with high speed and large pressure drives the crank to move, significantly improving the refueling speed. Specifically, the pressure can reach 10,000 PSI. In this embodiment, there is also a voltage stabilization circuit, a voltage acquisition circuit, a start switch, and a lighting switch. The microcontroller chip is communicatively connected to the voltage stabilization circuit, the voltage acquisition circuit, the start switch, and the lighting switch respectively. The voltage stabilization circuit is also electrically connected to the motor drive power circuit. There is also a quantitative refueling switch button. The Hall counting module is specifically a Hall sensor. The user can convert the demand into the counting times of the Hall sensor through the quantitative refueling switch button, so as to perform quantitative refueling according to the counting times, thus eliminating the errors caused by traditional mechanical filling. Further, by detecting the magnet trigger pulse signal of the Hall sensor, the precise tracking of the crank stroke can be realized, solving the technical problem that it is difficult to accurately control the butter filling amount in the prior art, significantly improving the accuracy and automation degree of the butter filling amount, avoiding resource waste, and at the same time reducing the wear risk of the equipment caused by insufficient lubrication.
[0038] As a preferred embodiment, there is also a chip power supply module, and the chip power supply module is electrically connected to the control module, the motor drive module, and the Hall counting module respectively.
[0039] The chip power supply module is also electrically connected to a low-power consumption circuit, and the low-power consumption circuit is electrically connected to the voltage stabilization circuit, the voltage acquisition circuit, the start switch, and the lighting switch respectively.
[0040] As a preferred embodiment, there is also an LED module, and the LED module is electrically connected to the chip power supply module. Specifically, the LED module is electrically connected to the chip power supply module through the lighting switch and the low-power consumption circuit.
[0041] As a preferred embodiment, as Figure 3 shown, the LED module includes a resistor R1, a resistor R2, a resistor R3, a connector J1, and a transistor Q1. The resistor R1 is connected to the collector of the transistor Q1 through the connector J1. The emitter of the transistor Q1 is grounded. The base of the transistor Q1 is grounded through the resistor R3, and the base of the transistor Q1 is also connected to the resistor R2. There is also a gear shift switch. By adjusting the gear ratio of the internal gears of the grease gun through the gear shift switch, the high and low gears can be switched. The refueling speed in the high-speed gear can reach 290 g / minute, and the refueling speed in the low-speed gear can reach 190 g / minute.
[0042] For the traditional manual greasing of excavators, it takes about 10 minutes to complete the greasing of a single joint. When using a grease gun driven by a brushed motor, due to the relatively weak pressure and low rotational speed, it takes about 1.5 minutes to complete the greasing of a single joint. In the present invention, the brushless motor has the characteristics of high rotational speed and large pressure. Therefore, it only takes 1 minute to complete the greasing of a single joint. At the same time, since there is a process of plunger movement for energy storage and pressure boosting during the oil output of the grease gun, the load change of the motor during operation is relatively large. This working condition causes relatively large damage to the carbon brushes of the traditional brushed motor. When the load is heavy, the electric spark at the contact position of the carbon brush is obvious. While the brushless motor commutates through electronic devices, there is no electric spark. The working life of the brushless motor is only limited by the bearing, and the nominal working life of the whole machine can reach 300 - 500 cycles. Each cycle supports an oil volume of 500g. The products of brushed motors can only reach 200 cycles, and the life is even lower under working conditions with high pressure requirements. Through the above comparison, it can be seen that the present invention not only significantly improves the greasing efficiency but also extends the service life of the device.
[0043] The above - described specific implementation manners are the preferred implementation manners of the high - pressure quantitative oil - output grease gun control method and the high - pressure quantitative oil - output grease gun of the present invention, and do not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made according to the shape and structure of the present invention are within the protection scope of the present invention.
