[0027] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0028] The invention discloses a detection method for detecting the distribution amount of a distributor and a detection device for detecting the distribution amount of a distributor. The detection device is used to detect the distribution amount of an oil and gas distributor, so as to screen out products that do not meet the requirements.

[0029] like Figure 6 and Figure 7 As shown, the left and right sides of the distributor 200 are provided with an oil inlet 201 and an air inlet 202, and the bottom end of the distributor 200 is installed with an output connector 203. During testing, the oil inlet 201 is connected to lubricating oil, and the air inlet 202 is connected to compressed air, and the mixed oil film is output from the output connector 203.

[0030] like Figure 2 As shown, the detection device 100 includes a support frame 10 , a plurality of connection devices 20 slidably mounted on the support frame 10 , and a driving device 30 slidably mounted on the support frame 10 .

[0031] The detection method for detecting the amount of dispenser distribution of the present invention comprises the following steps, and the process can be referred to as follows: Figure 4 and Figure 5 :

[0032] Step 1: The driving device 30 drives the multiple distributors 200 placed on the support frame 10 at intervals on the left and right to move closer to each other, and the connecting device 20 connects the distributors 200 in series, so that the oil inlets of the distributors 200 are connected to each other, and the air inlets 202 of the distributors 200 are connected to each other, and the output connector 203 of the distributor 200 is connected to a collecting meter 40, and the collecting meter 40 collects the oil mist output by the output connector 203;

[0033] Step 2: Inject compressed air into any air inlet 202. Since the distributors 200 are interconnected, the compressed air is injected into each distributor 200. Inject lubricating oil into any oil inlet 201. Since the distributors 200 are interconnected, the lubricating oil is injected into each distributor 200. The injected compressed air and lubricating oil are mixed to produce an oil film. This process is called oiling.

[0034] Step 3: When the preset oiling times or oiling duration is reached, the injection of compressed air and the injection of lubricating oil are stopped, and the amount of oil collected by the collecting meter 40 is measured;

[0035] Step 4: sort the dispensers 200 that deviate from the normal range value according to the measurement results.

[0036] If the oil volume falls within the normal range, it indicates that the tested distributor 200 is qualified. If the oil volume deviates from the normal range, it indicates that the tested distributor 200 is unqualified or abnormal. Therefore, whether the tested distributor 200 is qualified or not is distinguished according to the measured oil volume value.

[0037] In the present invention, the detection method for detecting the distribution amount of the distributor provided can detect multiple distributors 200 at one time, and the detection efficiency is high. In addition, the distributors 200 are connected in series using the connecting device 20, and the oil inlet 201 and the air inlet 202 of each distributor 200 are connected to each other. It is only necessary to input lubricating oil into one of the oil inlets 201 and compressed air into one of the air inlets 202 to perform the detection, and it is not necessary to connect each distributor 200 to the air pipe and the oil pipe, so the detection operation is more convenient.

[0038] Preferably, the oil volume is measured by measuring the volume of the oil collected by the collecting meter 40. In the embodiment provided by the present invention, the collecting meter 40 is configured as a measuring cylinder, and the oil volume can be directly known by observing the scale reached by the oil volume, which is convenient for observation. Furthermore, the scale reached by the oil volume can be collected using a CCD device, and of course, a visual method can also be used.

[0039] According to actual needs, the collecting meter 40 can also be configured as a measuring cup, a beaker or a measuring cylinder, etc., and the oil volume can be measured by measuring the weight of the oil collected by the collecting meter 40. Furthermore, an electronic scale is used to calculate the weight at this time to facilitate knowing the weight of the oil volume, and a CCD device can be used to collect the weight value of the oil volume, and of course, a visual method can also be used.

[0040] like Figure 1 As shown, in the embodiment provided by the present invention, the output connector 203 is connected to the collecting meter 40 through the hose 41, but it is not limited thereto.

[0041] The detection device 100 of the present invention further includes an alarm (not shown in the drawings), which issues an alarm when the test result deviates from the normal range, and promptly reminds people that the currently detected dispenser 200 has defective products and needs to be sorted. The alarm includes but is not limited to alarm sound (buzzer, alarm sound), screen signal, text signal, short message, email, and network push.

[0042] like Figures 1 to 5 , Figure 8 and Fig. 9 As shown, a driving member 31 is installed at the output end of the driving device 30, and the driving device 30 drives each distributor 200 to move closer to each other with the help of the driving member 31. The driving member 31 connects the oil inlet 201 and the air inlet 202 of the distributor 200 located at the far right end. The driving member 31 is provided with an oil delivery port 32 and an air delivery port 33, and lubricating oil is injected through the oil delivery port 32, and compressed air is injected through the air delivery port 33. With the help of the provided driving member 31, it is convenient to drive each distributor 200 to move closer to each other, and it is convenient to centrally inject lubricating oil through the oil delivery port 32, and it is convenient to centrally inject compressed air through the air delivery port 33. In the embodiment provided by the present invention, the oil delivery port 32 is on the top and the air delivery port 33 is on the bottom, but it is not limited to this layout. Preferably, in the embodiment provided by the present invention, the driving device 30 is configured as a driving handle with a screw nut pair, which drives the driving member 31 to move linearly left and right. Of course, according to actual needs, the driving device 30 can also be configured as a linear motor or a cylinder.

[0043] The detection device 100 of the present invention further includes a pressure oil gauge (not shown in the drawings) installed on the support frame 10, the pressure oil gauge is connected to the oil inlet 201 of the distributor 200 located at the leftmost end, and the pressure oil gauge monitors the oil pressure of the injected lubricating oil. When the oil pressure of the injected lubricating oil deviates from the preset normal value, the pressure oil gauge sends a pause test signal to remind people to clear the obstacle in time. Preferably, the oil pressure of the input lubricating oil is too high or too low, which may affect the detection result, so it is necessary to avoid injecting too high or too low lubricating oil.

[0044] The output connector 203 outputs oil mist, and the collecting meter 40 collects the oil mist and gathers it into oil. Since the amount of oil mist output each time the oil is pumped is very small, a single measurement is not realistic, so it is best to measure the collected oil after a considerable time or a considerable number of oiling processes. In the detection method for the dispenser distribution amount detection provided by the present invention, after 50 to 500 oiling processes, preferably 200 times, the amount of oil collected by the collecting meter 40 is measured. Of course, according to actual needs, the length of the oiling can also be measured by time. After 2 to 24 hours of oiling process, preferably 12 hours, the amount of oil collected by the collecting meter 40 is measured.

[0045] The detection device 100 of the present invention further includes a position sensor (not shown in the drawings) and a decentralized driver (not shown in the drawings).

[0046] After measuring the amount of oil collected by the collecting meter 40, that is, after step 3, the detection method for detecting the amount of oil distributed by the dispenser of the present invention further includes step 3.1: the position sensor detects whether the driving device 30 is in the initial position, that is, whether the driving device 30 is in the initial position without pushing the distributor 200 to move together. When the driving device 30 is detected to be in the initial position, the dispersion driver disperses the plurality of connecting devices 20. At this time, the state is as follows: Figure 4 As shown, the connecting devices 20 are separated from each other, and the distributors 200 are also dispersed and no longer close to each other. At this time, the distributor 200 can be easily removed from the support frame 10. Preferably, the position sensor is an infrared sensor, and the dispersion drive can be a manipulator, which is used to separate the connecting devices 20, thereby dispersing the connecting devices 20.

[0047] The detection device 100 of the present invention further includes a liquid pouring robot (not shown in the drawings). After sorting the dispenser 200, the detection method for detecting the distribution amount of the dispenser of the present invention further includes step 5: the liquid pouring robot removes the collection meter 40 and then flips the collection meter 40 to pour out the oil collected by the collection meter 40, and turns the collection meter 40 upside down to dry the collection meter 40 for the next detection. Preferably, the liquid pouring robot also dries the collection meter 40 by air blowing, thermal evaporation or spin drying to accelerate the drying of the collection meter 40.

[0048] like Figure 1 and Figure 2 As shown, the detection device 100 of the present invention uses a measuring cylinder stand 50 to support the collecting meter 40. Since there are multiple dispensers 200 to be detected at the same time, there are multiple collecting meter 40 carried by the measuring cylinder stand 50.

[0049] like Figures 1 to 5As shown, an inverted bracket 60 is provided above the support frame 10, and the liquid pouring robot puts the inverted collecting meter 40 into the inverted bracket 60, and the collecting meter 40 is carried by the inverted bracket 60. The measuring cylinder placement frame 50 and the inverted bracket 60 are provided with through holes for the collecting meter 40 to pass through, so that the collecting meter 40 can be passed through and carried.

[0050] like Figures 1 to 7 The connecting device 20 comprises a support block 21 and a connecting oil pipe 22 and a connecting air pipe 23 mounted on the support block 21. The connecting oil pipe 22 connects two adjacent oil inlets 201, and the connecting air pipe 23 connects two adjacent air inlets 202, thereby realizing the serial connection of each distributor 200. The support frame 10 is mainly composed of a plurality of rods, and the connecting device 20 and the driving member 31 are slidably arranged on the support frame 10 by sliding on the above-mentioned rods.

[0051] The following briefly introduces the detailed steps of the detection method for detecting the dispensing amount of the dispenser of the present invention:

[0052] Step 1: Control the driving device 30 to be in the initial position and disperse the multiple connecting devices 20. At this time, the state is as follows: Figure 3 The multiple dispensers 200 to be tested are installed into the support frame 10 at intervals on the left and right, and the support frame 10 provides support for the dispensers 200. At this time, the state is as follows Figure 4 The driving device 30 drives the multiple distributors 200 to move closer to each other, and the connecting device 20 connects the distributors 200 in series, so that the oil inlets 201 of the distributors 200 are connected to each other, and the air inlets 202 of the distributors 200 are connected to each other, and the output connector 203 of the distributor 200 is connected to a collecting meter 40. At this time, the state is as follows Figure 5 He Ru Figure 1 As shown;

[0053] Step 2: inject lubricating oil into the oil delivery port 32, and inject compressed air into the air delivery port 33. The injected compressed air and lubricating oil are mixed in the distributor 200 to obtain oil mist, which is output through the output connector 203;

[0054] Step 3: When the preset oiling times or oiling duration is reached, the injection of compressed air and the injection of lubricating oil are stopped, and the amount of oil collected by the collecting meter 40 is measured;

[0055] Step 3.1: The driving device 30 is reset to the initial position. The position sensor detects whether the driving device 30 is in the initial position. When the driving device 30 is detected to be in the initial position, the dispersion driver disperses the multiple connecting devices 20 so that each distributor 200 is dispersed synchronously. At this time, the state is roughly the same as Figure 4 As shown;

[0056] Step 4: sort the dispensers 200 that deviate from the normal range according to the measurement results, that is, pick out the dispensers 200 that fail the test or have abnormalities, and unload the dispensers 200 that pass the test. At this time, the state is roughly the same as Figure 2 As shown;

[0057] Step 5: The liquid pouring robot takes down the collecting meter 40 on the measuring cylinder placement rack 50 and flips the collecting meter 40 to pour out the oil in the collecting meter 40. The liquid pouring robot also dries the collecting meter 40 by air blowing, thermal evaporation or spin drying, and then installs the inverted collecting meter 40 into the inverting bracket 60.

[0058] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
