[0046] The clamping mechanism is symmetrically provided with two sets with the axis of the rotating bottom plate 5 as the symmetry point, so as to more evenly and stably clamp the processed plastic shell cyclone coarse filter.

[0047] Adjustable feet 35 are connected downwardly at the four corners of the frame 1, which facilitates leveling the frame 1 when the ground is not flat enough. The rotary power device 32 is a rotary cylinder, and of course a reduction motor can also be used.

[0048] The present invention also discloses a method for detecting glue tightening using the above-mentioned integrated device for detecting glue tightening of a plastic shell cyclone coarse filter, which is performed according to the following steps:

[0049] First, the preparation work.

[0050] Before the tightening and gluing inspection operation is performed, the speed of the rotating blade 33 of the qualified plastic shell cyclone coarse filter is measured first, specifically, the rotating power device 32 is started, the output shaft of the rotating power device 32 drives the lever 34 to rotate, so that the lever 34 moves the rotating blade 33 of the plastic shell cyclone coarse filter, and then the speed R of the rotating blade 33 after being moved is measured. R is a positive real number and is greater than or equal to 6;

[0051] Before the first step, the connecting tube 6 of the internal structure of the molded case cyclone coarse filter to be processed is buckled on the positioning block 7 from top to bottom, and the connecting tube 6 and the positioning block 7 are interference fit; at this time, the wrench sleeve 23 of the electric torque wrench 22 and the central axis 24 of the molded case cyclone coarse filter are located on the same axis and the wrench sleeve 23 is located directly above the central axis 24 of the molded case cyclone coarse filter; the hexagonal nut at the bottom end of the central axis is downwardly inserted into the hexagonal inner sleeve 13 for positioning, thereby preventing the central axis 24 of the molded case cyclone coarse filter from rotating when tightening;

[0052] Adjust the tightening torque of the electric torque wrench 22 to the tightening torque of the upper nut 25 to complete the preparation work;

[0053] The first step is the compaction step;

[0054] Then, the pressing cylinder 15 is operated to retract the extended rod of the pressing cylinder 15 downward, thereby driving the force transmission plate 16 and the pressing column 17 to move downward, so that the pressing column 17 presses the edge top of the connecting plate 18 of the molded case cyclone coarse filter to prevent the internal structure of the molded case cyclone coarse filter from rotating during the tightening step;

[0055] The second step is the tightening step; operate the lifting cylinder 20 to retract the extension rod of the lifting cylinder 20 downward, thereby driving the connecting plate 21 and the electric torque wrench 22 to move downward, and the wrench sleeve 23 of the electric torque wrench 22 is sleeved on the upper nut 25 on the central axis 24 of the plastic shell cyclone coarse filter; start the electric torque wrench 22 to tighten the upper nut 25; after tightening, stop the electric torque wrench 22, so that the extension rod of the lifting cylinder 20 and the extension rod of the clamping cylinder 15 are respectively reset upward; after the extension rod of the clamping cylinder 15 is reset upward, delay 0.5 seconds before proceeding to the third step;

[0056] The third step is the gluing step; the gluing step is to start the gluing cylinder 27, the extension rod of the gluing cylinder 27 extends to the right, driving the glue spray nozzle 29 to move rightward to the edge of the connecting plate 18 of the plastic shell cyclone coarse filter and facing downward to the inner surface of the side wall of the connecting plate 18;

[0057] Open the dispensing solenoid valve 30 and start the speed regulating motor 4 at the same time. The speed regulating motor 4 drives the rotating base plate 5 and the positioning block 7 to rotate through the transmission mechanism; the positioning block 7 drives the internal structure of the plastic shell cyclone coarse filter to rotate through the connecting tube 6 under the action of friction. At this time, the central shaft 24 will not rotate because the hexagonal nut at its bottom is positioned by the inner hexagonal sleeve 13; after the dispensing solenoid valve 30 is opened, the glue is sprayed downward from the dispensing nozzle 29 to the inner surface of the side wall of the connecting disk 18. As the internal structure of the plastic shell cyclone coarse filter rotates, the glue is evenly sprayed on the inner surface of the side wall at the circumferential edge of the connecting disk 18 of the plastic shell cyclone coarse filter; the time for spraying the glue is 10±1 seconds;

[0058] After the glue is sprayed, the glue dispensing solenoid valve 30 is closed and the speed regulating motor 4 is turned off at the same time, and the extended rod of the glue dispensing cylinder 27 is retracted to the left to complete the glue dispensing operation; after the extended rod of the glue dispensing cylinder 27 is retracted to the left, the third step is performed after a delay of 0.5 seconds to prevent the glue dispensing cylinder 28 from blocking the rotation of the rotating blade 33;

[0059] The fourth step is a detection step; the rotating power device 32 is started, and the output shaft of the rotating power device 32 drives the lever 34 to rotate and moves the rotating blades 33 of the plastic shell cyclone coarse filter;

[0060] Measure the actual rotation speed X revolutions per second of the rotating blade 33 after it is turned. If the absolute value of the difference between X and R is less than or equal to 2, the rotating blade 33 of the molded case cyclone coarse filter is qualified; if the absolute value of the difference between X and R is greater than 2, the rotating blade 33 of the molded case cyclone coarse filter is unqualified;

[0061] The fifth step is to remove the internal structure of the plastic shell cyclone coarse filter from the rotating bottom plate 5 after the test is completed;

[0062] The first step to the fifth step are repeated in a cycle, and each cycle completes a tightening and gluing inspection operation of the internal structure of the plastic shell cyclone coarse filter.

[0063] The start-up time of the electric torque wrench 22 in the second step is 5±0.5 seconds, which can ensure tightening without wasting time.

[0064] The integrated device for detecting the tightening and coating of the plastic shell cyclone coarse filter also includes an electric control device, which is connected to an audible and visual alarm, an infrared detection switch and a display screen. The rotation path of the rotating blade 33 passes through the detection route of the infrared detection switch. The electric control device calculates the actual rotation speed X of the rotating blade 33 after being turned according to the following formula: X = the number of times the infrared detection switch is triggered within 3 seconds / 3*the total number of rotating blades 33; taking the average rotation speed within 3 seconds, compared with measuring only 1 second, avoids the problem of large friction when the rotating blade rotates and the rapid drop in rotation speed after 1 second, so the accuracy is higher. The electric control device is installed in the electric control box on the frame 1, and the electric control device and the audible and visual alarm, infrared detection switch and display screen connected thereto are not shown in the figure.

[0065] The electronic control device is also connected to the dispensing solenoid valve 30, the electric torque wrench 22, the clamping cylinder 15, the lifting cylinder 20, the speed regulating motor 4, the glue coating cylinder 27 and the rotating power device 32; the first step to the fourth step are all controlled by the electronic control device;

[0066] In the fourth step, the electronic control device calculates the absolute value of the difference between X and R. If the absolute value is less than or equal to 2, the internal structure of the plastic shell cyclone coarse filter is judged to be a qualified product; if the absolute value is greater than 2, the internal structure of the plastic shell cyclone coarse filter is judged to be an unqualified product, and the electronic control device controls the sound and light alarm to send out a sound and light alarm to prompt the staff to handle the unqualified product.

[0067] The electric control device is a single chip microcomputer or an integrated circuit, preferably a PLC.

[0068] The present invention converts the speed at rated flow rate into the speed at which the lever of the integrated device for testing the tightness and gluing of the molded case cyclone coarse filter is turned through the speed measurement operation, which greatly facilitates the testing operation. According to experiments, after the speed at which the lever is turned is converted into the speed at which the measuring lever is turned, the accuracy of the measurement is basically the same as the accuracy of the speed at rated flow rate, and the accuracy rate of identifying qualified and unqualified products reaches 99.9%.

[0069] After the extending rod of the clamping cylinder is reset upward, there is a delay of 0.5 seconds before the third step is performed. This can prevent the phenomenon that the extending rod of the clamping cylinder has not yet reset upward when the speed control motor is started in the third step, and the plastic case cyclone coarse filter is still clamped, thereby preventing the plastic case cyclone coarse filter from being unable to rotate when the speed control motor is started, causing damage to the speed control motor and the transmission mechanism, and even damaging the speed control motor in serious cases.

[0070] If the glue spraying time is too short, the thickness of the sprayed glue cannot ensure that the plastic shell is firmly bonded; if the glue spraying time is too long, it will cause a waste of glue.

[0071] The time for spraying the glue is 10±1 seconds (including the two end values ​​of 9 seconds and 11 seconds). After testing, the thickness of the glue sprayed on the inner surface of the side wall at the circumferential edge of the connecting plate meets the requirements for bonding the plastic shell of the plastic shell cyclone coarse filter, while avoiding waste of glue.

[0072] The start-up time of the electric torque wrench is 5±0.5 seconds, which can ensure tightening without wasting time.

[0073] Taking the average speed within 3 seconds, compared with measuring only 1 second, avoids the problem of high friction when the rotating blades rotate and the sharp drop in speed after 1 second, and thus has a higher degree of accuracy.

[0074] By using the electronic control device, the operations from the first step to the fourth step can be automatically implemented by the electronic control device, which improves work efficiency, reduces the labor intensity of workers, and can automatically determine whether the internal structure of the plastic shell cyclone coarse filter is an unqualified product, and correspondingly prompt the staff to take corresponding measures through the sound and light alarm.

Although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
