[0022] In order to better achieve the purpose of the present invention, the present invention also provides a method for using an intelligently controlled plastic article sealing performance detection device, comprising the following steps:

[0023] Step 1: When a sealing test is performed on a plastic article with ordinary sealing requirements, the system controls port 1 of electromagnetic three-way valve 1 to be connected with port 3, controls port 1 of electromagnetic three-way valve 3 to be connected with port 3, controls port 2 of electromagnetic three-way valve 4 to be connected with port 3, and controls port 1 of electromagnetic three-way valve 2 to be connected with port 2. At this time, electromagnetic three-way valve 4 is closed, and the air pump is started. Air flows in from port 2 of electromagnetic three-way valve 2 and sequentially passes through port 1 of electromagnetic three-way valve 2, air pump, port 1 of electromagnetic three-way valve 1, port 3 of electromagnetic three-way valve 1, three-way pipe 1, air inlet end 1 of two-inlet and two-outlet pneumatic slip ring, air outlet end 1 of two-inlet and two-outlet pneumatic slip ring, port 1 of electromagnetic three-way valve 3, and port 3 of electromagnetic three-way valve 3. Finally, air flows into the air inlet to pressurize the inside of the plastic article. When the pressure reaches the preset value, electromagnetic three-way valve 3 is closed.

[0024] Step 2: When the gas in the plastic article in step 1 is discharged, the system controls the port 2 of the electromagnetic three-way valve 4 to be connected with the port 3 thereof, and the high-pressure gas in the plastic article is discharged through the exhaust port, the port 3 of the electromagnetic three-way valve 4, and the port 2 of the electromagnetic three-way valve 4 in sequence;

[0025] Step 3: When the sealing performance of the special plastic article is tested, the system controls the port 2 of the electromagnetic three-way valve 3 to be connected with the port 3, closes the electromagnetic three-way valve 4, and the helium in the helium cylinder flows into the plastic article through the port 2 of the electromagnetic three-way valve 3, the port 3 of the electromagnetic three-way valve 3, and the air inlet in sequence, and then controls the port 1 of the electromagnetic three-way valve 3 to be connected with its port 3, and repeats step 1;

[0026] Step 4, when the gas in the plastic article in step 3 is discharged, the system controls the port 1 of the electromagnetic three-way valve 2 to be connected with its port 3, controls the port 1 of the electromagnetic three-way valve 1 to be connected with its port 2, controls the port 1 of the electromagnetic three-way valve 4 to be connected with its port 3, starts the air pump, and the mixed gas in the plastic article passes through the exhaust port, the port 3 of the electromagnetic three-way valve 4, the port 1 of the electromagnetic three-way valve 4, the air inlet end 2 of the two-inlet and two-outlet pneumatic slip ring, the air outlet end 2 of the two-inlet and two-outlet pneumatic slip ring, the three-way pipe 2, the port 3 of the electromagnetic three-way valve 2, the port 1 of the electromagnetic three-way valve 2, the air pump, the port 1 of the electromagnetic three-way valve 1, and finally is discharged into the helium recovery equipment through the port 2 of the electromagnetic three-way valve 1.

[0027] Step 5: When adapting to plastic objects of different heights, start the double-slide linear module, which drives the double-station tooling component, the blocking and dividing component, and the detection component to synchronously adjust the overall height;

[0028] Step 6: When adapting to plastic objects with different maximum radii, start the bidirectional linear module, and the two output slides of the bidirectional linear module move in opposite directions to adjust the spacing of the caps;

[0029] Step 7: The output slide on the right side of the bidirectional linear module drives the connecting rod to move, and the connecting rod drives the middle connecting column to move. Since the left connecting column of the two-stage scissor mechanism is fixed to the first mounting plate, the two-stage scissor mechanism as a whole performs a scissor movement. The right end connecting column of the two-stage scissor mechanism drives the installation slide to slide in the limit slide groove, and the installation slide drives the second cylinder to adjust the position;

[0030] Step 8: When sealing the plastic article, the output end of the second cylinder extends to block the rightmost plastic article, the first cylinder drives the spline shaft to descend, the spline shaft drives the cover to descend, and the outer wall of the conical sealing cup in the cover contacts and seals the mouth of the plastic article;

[0031] Step nine, when the plastic article has a general sealing requirement, after executing steps one and two, the air pressure sensor is used to detect whether the air pressure of the plastic article changes;

[0032] Step 10: When the plastic article has a special sealing requirement, execute Step 8, Step 3, and Step 4. First, start the motor on the right side again. The output end of the motor drives the spline sleeve to rotate through the pulley assembly. The spline sleeve drives the spline shaft to rotate. The spline shaft drives the cover to rotate. The cover drives the conical sealing cup to rotate. The conical sealing cup drives the plastic article on the right side to rotate on the belt conveyor line. Start the fan to increase the air flow rate, and detect the helium through the helium detector.

[0033] Step eleven, when the detection is completed, start cylinder one to reset so that the conical sealing cup is separated from the mouth of the plastic object, and at the same time the output end of cylinder two retracts, and start the belt conveyor line again to transport the next group of two plastic objects to the corresponding position.

[0034] Compared with the prior art, the present invention has the following beneficial effects: 1. Plastic articles are transported by a belt conveyor line, and the heights of a double-station tooling assembly and a blocking and dividing assembly are synchronously adjusted by a double-slide linear module to meet the detection requirements of plastic articles of different heights. The spacing between two rotating downward pressing assemblies is adjusted by a bidirectional linear module to meet the requirements of plastic articles of different maximum radii. The sealing assembly is driven by a rotating downward pressing assembly to press down, seal and rotate the plastic articles. The blocking and dividing assembly is used to block and position the plastic articles, and plastic articles that do not meet the sealing detection standards are removed.

[0035] 2. When adapting to plastic objects with different maximum radii, the distance that needs to be adjusted at the output end of cylinder 2 is twice the capping distance at the right end. The movement distance of the right-end connecting column of the two-stage scissor mechanism is twice the distance of the middle connecting column, so as to realize the synchronous adjustment of the capping position of cylinder 2 and the right end.

[0036] 3. Realize intelligent switching of two detection modes for the system control gas circuit control components and double-station tooling components for two types of plastic items with general sealing requirements and characteristic sealing requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] Step 2: When the gas in the plastic article in step 1 is discharged, the system controls the port 2 of the electromagnetic three-way valve 447 to be connected to the port 3 thereof, and the high-pressure gas in the plastic article is discharged through the exhaust port 534, the port 3 of the electromagnetic three-way valve 447, and the port 2 of the electromagnetic three-way valve 447 in sequence;

[0071] Step 3: When the sealing performance of the special plastic article is tested, the system controls the port 2 of the electromagnetic three-way valve 46 to be connected with the port 3, closes the electromagnetic three-way valve 47, and the helium in the helium cylinder 48 flows into the plastic article through the port 2 of the electromagnetic three-way valve 46, the port 3 of the electromagnetic three-way valve 46, and the air inlet 533 in sequence, and then controls the port 1 of the electromagnetic three-way valve 46 to be connected with its port 3, and repeats step 1;

[0072] Step 4, when the gas in the plastic article in step 3 is discharged, the system controls the port 1 of the electromagnetic three-way valve 2 49 to be connected with the port 3 thereof, controls the port 1 of the electromagnetic three-way valve 1 42 to be connected with the port 2 thereof, controls the port 1 of the electromagnetic three-way valve 47 to be connected with the port 3 thereof, starts the air pump 41, and the mixed gas in the plastic article passes through the exhaust port 534, the port 3 of the electromagnetic three-way valve 47, the port 1 of the electromagnetic three-way valve 47, the air inlet end 2 of the two-inlet and two-outlet pneumatic slip ring 45, the air outlet end 2 of the two-inlet and two-outlet pneumatic slip ring 45, the three-way pipe 2 44, the port 3 of the electromagnetic three-way valve 2 49, the port 1 of the electromagnetic three-way valve 2 49, the air pump 41, the port 1 of the electromagnetic three-way valve 1 42, and finally is discharged into the helium recovery equipment through the port 2 of the electromagnetic three-way valve 1 42.

[0073] The following steps are also included:

[0074] Step 5: When adapting to plastic objects of different heights, start the double-slide linear module 3, and the double-slide linear module 3 drives the double-station tooling component 5, the blocking and dividing component 6, and the detection component 7 to adjust the height synchronously as a whole;

[0075] Step 6: When adapting to plastic objects with different maximum radii, start the bidirectional linear module 51, and the two output slides of the bidirectional linear module 51 move in opposite directions to adjust the spacing of the caps 531;

[0076] Step 7: The output slide on the right side of the bidirectional linear module 51 drives the connecting rod 64 to move, and the connecting rod 64 drives the middle connecting column to move. Since the left connecting column of the two-stage scissor mechanism 63 is fixed to the mounting plate 1 61, the two-stage scissor mechanism 63 as a whole performs a scissor movement, and the right end connecting column of the two-stage scissor mechanism 63 drives the installation slide 65 to slide in the limiting slide groove 62, and the installation slide 65 drives the cylinder 2 66 to adjust the position;

[0077] Step 8, when sealing the plastic article, the output end of the second cylinder 66 extends to block the rightmost plastic article, the first cylinder 522 drives the spline shaft 523 to descend, the spline shaft 523 drives the sealing cover 531 to descend, and the outer wall of the conical sealing cup 532 in the sealing cover 531 contacts and seals the mouth of the plastic article;

[0078] Step nine, when the plastic article has a normal sealing requirement, after executing steps one and two, the air pressure sensor 71 is used to detect whether the air pressure of the plastic article changes;

[0079] Step 10, when the plastic article has a special sealing requirement, execute step 8, step 3, and step 4, first start the motor 525 on the right side, the output end of the motor 525 drives the spline sleeve 524 to rotate through the pulley assembly 526, the spline sleeve 524 drives the spline shaft 523 to rotate, the spline shaft 523 drives the cover 531 to rotate, the cover 531 drives the conical sealing cup 532 to rotate, the conical sealing cup 532 drives the plastic article on the right side to rotate on the belt conveyor line 2, start the fan 73 to increase the air flow rate, and detect the helium through the helium detector 74;

[0080] Step 11, start the motor (525) on the left side and repeat step 10;

[0081] Step 12, when the detection is completed, start the cylinder 1 522 to reset so that the conical sealing cup 532 is separated from the mouth of the plastic object, and at the same time the output end of the cylinder 2 66 is retracted, and the belt conveyor line 2 is started again to transport the next group of two plastic objects to the corresponding position;

[0082] Step thirteen, the plastic articles detected to be leaking are removed by starting the cylinder three 67.

[0083] When the present invention is used, it realizes intelligent switching of two detection modes of the system control gas circuit control component 4 and the double-station tooling component 5 for two plastic articles with common sealing requirements and characteristic sealing requirements.

[0084] When the present invention is used, since the helium detector 74 can detect extremely weak helium leakage, it is suitable for sealing performance testing of plastic articles in special scenarios such as medical treatment and aerospace;

[0085] When the present invention is used, the pulley assembly 526 adopts the existing technology sold on the market, which is composed of two synchronous pulleys and a synchronous belt;

[0086] When the present invention is used, when the helium detector 74 is detecting, the plastic article on the right side is first filled with helium, thereby avoiding the situation where two plastic articles are filled with helium at the same time, causing the helium detector 74 to be unable to determine the specific plastic article that is leaking.

[0087] When the present invention is used, when detecting helium leakage, the plastic article is driven to rotate, so that the helium detector 74 can detect its leakage in all directions, and at the same time, the fan 73 attracts the airflow to the helium detector 74 to speed up the detection speed.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
