[0013] How the device operates:

[0014] Step 1: Loading: The first vacuum box and the second vacuum box are evacuated to a vacuum state by a vacuum pump, and the vacuum degree inside them can be observed by a vacuum pressure display. The packaged bottles of the sample products to be tested are transported to the bottom end of the test box by a set of first conveyor belts;

[0015] Step 2: Fixing, the detection box can be lowered by the second electric push rod until the suction cup contacts the top of the product packaging bottle. At this time, the suction cup can compress the spring, and under the action of the spring, the bottom end of the suction cup is tightly fitted with the top of the product packaging bottle. Then the first three-way solenoid valve and the first solenoid valve are operated. At this time, the air between the suction cup and the product packaging bottle enters the interior of the first vacuum box through the fourth connecting pipe, the second connecting pipe and the first connecting pipe. Under the action of the external atmospheric pressure, the product packaging bottle is sucked by the suction cup;

[0016] Step 3: Transfer, the detection box is moved upward by the second electric push rod, the product packaging bottle can be lifted by the suction cup, and the product packaging bottle is moved to the top of the bottom plate by the moving plate, the second electric push rod, the detection box and the suction cup. The detection box and the product packaging bottle are moved downward by the second electric push rod so that the product packaging bottle is respectively at the top of the pressure sensor, and the first three-way solenoid valve is operated again to allow outside air to enter the first connecting pipe. At the same time, the first connecting pipe at one end of the first vacuum box is closed. At this time, the suction cup no longer tightly sucks the product packaging bottle;

[0017] Step 4: Detection: The product packaged bottle inside the detection chamber can be detected by the pressure sensor. At this time, the second three-way solenoid valve works, and the second solenoid valve with the product packaged bottle inside the detection chamber also works. The seventh connecting pipe is opened by the second three-way solenoid valve, and the sixth connecting pipe is opened by the second solenoid valve. At this time, the air pressure inside the detection chamber can be instantly reduced by the second three-way solenoid valve, the seventh connecting pipe, the fifth connecting pipe, the sixth connecting pipe and the second solenoid valve. Then the second three-way solenoid valve and the second solenoid valve are instantly closed. The air pressure change inside the detection chamber is detected by the air pressure detection sensor. If the air pressure inside the detection chamber changes, the product packaged bottle inside the corresponding detection chamber is a sealed unqualified product, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe is connected to the outside air through the second three-way solenoid valve. By opening the second solenoid valve, the pressure inside the detection chamber can be made the same as the outside atmospheric pressure.

[0018] Step 5: Transfer again, the first three-way solenoid valve and the first solenoid valve are used to make the suction cup tightly suck the product packaged bottles again, the second electric push rod and the first electric push rod are used to move the detection box and the product packaged bottles to the first conveyor belt on the side of the second conveyor belt, and then the first electric push rod and the second electric push rod are used to reset the detection box and detect the next group of product packaged bottles again;

[0019] Step 6: Take away the unqualified product packaging bottles, detect the third electric push rod corresponding to the unqualified product packaging bottles, and move the fixed sleeve and the semicircular sleeve plate to one side of the product packaging bottle through the third electric push rod, and then the dual-axis motor works, and the arc buckle plate is moved through the gear and the tooth groove until one side of the limit block fits the inner wall of one end of the limit arc groove. At this time, the movement is stopped, and the fixed sleeve, the semicircular sleeve plate and the product packaging bottle are moved by the third electric push rod until the product packaging bottle is at the top of the second conveyor belt, and then the arc buckle plate is reset by the dual-axis motor and the gear. Finally, the fixed sleeve and the semicircular sleeve plate are reset again by the third electric push rod. At the same time, the third electric push rod can detect whether all unqualified product packaging bottles are at the top of the second conveyor belt. If there is an unqualified product packaging bottle at the top of the first conveyor belt, the second conveyor belt will not start at this time. Otherwise, the second conveyor belt will start to move the unqualified product packaging bottle away.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The first vacuum box and the second vacuum box can be evacuated into a vacuum state by a vacuum pump, and the vacuum degree inside can be observed by a vacuum pressure display. After the sample product packaging bottle to be tested is conveyed to the bottom end of the detection box by a group of first conveyor belts, the detection box can be lowered by the second electric push rod, so that the product packaging bottle is inside the detection chamber until the suction cup contacts the top end of the product packaging bottle. At this time, the spring can be compressed by the suction cup, and under the action of the spring, the bottom end of the suction cup is tightly fitted with the top end of the product packaging bottle. Then the first three-way solenoid valve and the first solenoid valve work. At this time, the air between the suction cup and the product packaging bottle enters the interior of the first vacuum box through the fourth connecting pipe, the second connecting pipe and the first connecting pipe. Under the action of the external atmospheric pressure, the air between the suction cup and the product packaging bottle enters the interior of the first vacuum box. The product packaging bottle is sucked by the suction cup, and the detection box is moved up by the second electric push rod until the bottom end of the limit ring is in contact with the inner wall of the bottom end of the limit groove. At this time, the product packaging bottle can be lifted by the suction cup, and then the first electric push rod is used to make the movable plate slide on the surface of the slide rod, and the product packaging bottle is moved to the top of the bottom plate through the movable plate, the second electric push rod, the detection box and the suction cup. The detection box and the product packaging bottle are moved down by the second electric push rod so that the product packaging bottle are respectively at the top of the pressure sensor. At this time, the first three-way solenoid valve is operated again to allow outside air to enter the first connecting pipe, and the first connecting pipe at one end of the first vacuum box is closed at the same time. At this time, the suction cup no longer tightly sucks the product packaging bottle, and the detection chamber can be detected by the pressure sensor. The product packaging bottle inside, at this time the second three-way solenoid valve works, and at the same time the second solenoid valve with the product packaging bottle inside the detection chamber also works, the seventh connecting pipe is opened through the second three-way solenoid valve, and the sixth connecting pipe is opened through the second solenoid valve. At this time, the air pressure inside the detection chamber can be instantly reduced through the second three-way solenoid valve, the seventh connecting pipe, the fifth connecting pipe, the sixth connecting pipe and the second solenoid valve, and then the second three-way solenoid valve and the second solenoid valve are instantly closed, and the air pressure change inside the detection chamber is detected by the air pressure detection sensor. If the air pressure inside the detection chamber changes, the product packaging bottle inside the corresponding detection chamber is a sealed unqualified product, otherwise it is a qualified product. After the inspection is completed, one end of the seventh connecting pipe is opened through the second three-way solenoid valve. It is connected to the outside air, and by opening the second solenoid valve, the internal pressure of the detection chamber can be made the same as the external atmospheric pressure, so that the second electric push rod can drive the detection box to move upward, and at the same time, the first three-way solenoid valve and the first solenoid valve are used to make the suction cup tightly suck the product packaging bottle again, and the second electric push rod and the first electric push rod are used to move the detection box and the product packaging bottle to the first conveyor belt on the side of the second conveyor belt, and then the first electric push rod and the second electric push rod are used to reset the detection box, and the next group of product packaging bottles are inspected again. At the same time, the third electric push rod corresponding to the unqualified product packaging bottle works, and the third electric push rod is used to move the fixed sleeve and the semicircular sleeve plate to one side of the product packaging bottle, and then the dual-axis motor works to move the arc buckle plate through the gears and tooth grooves.The arc gusset plate can be guided by the arc slide and the arc slide plate, and the moving distance of the arc gusset plate can be limited by the limiting arc groove and the limiting block. After the arc gusset plate drives the limiting block, it stops moving until one side of the limiting block fits into the inner wall of one end of the limiting arc groove. The third electric push rod can move the fixed sleeve, the semicircular sleeve plate and the product packaging bottle until the product packaging bottle is at the top of the second conveyor belt, and then the double-axis motor and the gear are used to reset the arc gusset plate, and finally the third electric push rod is used to reset the fixed sleeve and the semicircular sleeve plate again. At the same time, the third electric push rod can detect whether all unqualified product packaging bottles are at the top of the second conveyor belt. If the If there is an unqualified product packaged bottle at the top of the first conveyor belt, the second conveyor belt will not start. On the contrary, the second conveyor belt will start to move the unqualified product packaged bottle away. This device can complete the inspection work fully automatically and can also remove and move the unqualified product packaged bottles separately, further facilitating the user's inspection work. This device is simple and convenient to operate, and does not require multiple people to operate, further reducing practical costs. At the same time, this device uses negative pressure to perform inspections, and judges the sealing performance based on the pressure changes. This will not cause any contamination or damage to the product packaged bottles, and can also improve the accuracy of the inspection, while also further reducing the user's usage and maintenance costs.

At this time, the second three-way solenoid valve 35 works, and the second solenoid valve 33 with the product packaging bottle 11 inside the detection chamber 19 also works. The seventh connecting pipe 34 is opened by the second three-way solenoid valve 35, and the sixth connecting pipe 32 is opened by the second solenoid valve 33.

After the test is completed, one end of the seventh connecting pipe 34 is connected to the outside air through the second three-way solenoid valve 35. By opening the second solenoid valve 33, the pressure inside the detection chamber 19 can be made the same as the outside atmospheric pressure, thereby facilitating the second electric push rod 9 to drive the detection box 10 to move upward, facilitating the sealing test of the device, and at the same time protecting the product packaged bottle 11;

[0039] It should be noted that one end of the first vacuum box 12 and the second vacuum box 13 are both provided with a vacuum pump 14, and one end of the first vacuum box 12 and the second vacuum box 13 are both provided with a vacuum pressure display 15. A pipe groove 29 is opened at one end of the workbench 1, and a baffle 30 is fixedly connected to one end of the pipe groove 29 to provide a vacuum environment and ensure that the product packaging bottle 11 is normally upright. The baffle 30 prevents the first connecting tube 16 and the seventh connecting tube 34 from knocking down the product packaging bottle 11. The control panel 2 is electrically connected to the external power supply, and the control ends of the first conveyor belt 4, the second conveyor belt 5, the first electric push rod 8, the second electric push rod 9, the vacuum pump 14 and the vacuum pressure display 15 are all electrically connected to the control panel 2, so that the device can operate fully automatically.

[0040] The device operates as follows:

[0041] Step 1: Loading: The first vacuum box 12 and the second vacuum box 13 are evacuated to a vacuum state by a vacuum pump 14. The vacuum degree inside the vacuum box 12 and the second vacuum box 13 can be observed by a vacuum pressure display 15. The packaged bottle 11 of the sample product to be tested is transported to the bottom end of the detection box 10 by a set of first conveyor belts 4;

[0042] Step 2: Fixing, the detection box 10 can be lowered by the second electric push rod 9 until the suction cup 22 contacts the top of the product packaging bottle 11. At this time, the suction cup 22 can compress the spring 23. Under the action of the spring 23, the bottom end of the suction cup 22 is tightly fitted with the top of the product packaging bottle 11. Then the first three-way solenoid valve 17 and the first solenoid valve 28 are operated. At this time, the air between the suction cup 22 and the product packaging bottle 11 enters the interior of the first vacuum box 12 through the fourth connecting pipe 27, the second connecting pipe 18 and the first connecting pipe 16. Under the action of the external atmospheric pressure, the product packaging bottle 11 is sucked by the suction cup 22;

[0043] Step 3: Transfer, the detection box 10 is moved upward by the second electric push rod 9, and the product packaging bottle 11 can be lifted by the suction cup 22, and the product packaging bottle 11 is moved to the top of the bottom plate 36 by the movable plate 6, the second electric push rod 9, the detection box 10 and the suction cup 22. The detection box 10 and the product packaging bottle 11 are moved downward by the second electric push rod 9, so that the product packaging bottle 11 is respectively at the top of the pressure sensor 38, and the first three-way solenoid valve 17 is operated again to allow outside air to enter the first connecting pipe 16. At the same time, the first connecting pipe 16 at one end of the first vacuum box 12 is closed. At this time, the suction cup 22 no longer tightly sucks the product packaging bottle 11;

[0044] Step 4: Detection. The product packaged bottle 11 inside the detection chamber 19 can be detected by the pressure sensor 38. At this time, the second three-way solenoid valve 35 is activated, and the second solenoid valve 33 with the product packaged bottle 11 inside the detection chamber 19 is also activated. The seventh connecting pipe 34 is opened by the second three-way solenoid valve 35, and the sixth connecting pipe 32 is opened by the second solenoid valve 33. At this time, the air pressure inside the detection chamber 19 can be instantly reduced by the second three-way solenoid valve 35, the seventh connecting pipe 34, the fifth connecting pipe 31, the sixth connecting pipe 32, and the second solenoid valve 33. Then, the second three-way solenoid valve 35 and the second solenoid valve 33 are instantly closed. The air pressure change inside the detection chamber 19 is detected by the air pressure detection sensor 39. If the air pressure inside the detection chamber 19 changes, the product packaged bottle 11 inside the corresponding detection chamber 19 is a sealed product with unqualified sealing. Otherwise, it is a qualified product. After the detection is completed, one end of the seventh connecting pipe 34 is connected to the outside air by the second three-way solenoid valve 35. By opening the second solenoid valve 33, the pressure inside the detection chamber 19 can be made the same as the outside atmospheric pressure.

[0045] Step 5: Transfer again. The first three-way solenoid valve 17 and the first solenoid valve 28 are used to make the suction cup 22 firmly suck the product packaged bottles 11 again. The second electric push rod 9 and the first electric push rod 8 are used to move the detection box 10 and the product packaged bottles 11 to the first conveyor belt 4 on the side of the second conveyor belt 5. Then, the first electric push rod 8 and the second electric push rod 9 are used to reset the detection box 10 and detect the next group of product packaged bottles 11 again.

[0046] Step 6: Take away the unqualified product packaging bottle 11, detect the third electric push rod 42 corresponding to the unqualified product packaging bottle 11, and move the fixing sleeve 43 and the semicircular sleeve plate 44 to one side of the product packaging bottle 11 through the third electric push rod 42. Then the dual-axis motor 51 works, and the arc-shaped buckle plate 45 is moved through the gear 52 and the tooth groove 50 until one side of the limit block 49 fits with the inner wall of one end of the limit arc groove 48. At this time, the movement is stopped, and the fixing sleeve 43, the semicircular sleeve plate 44 and the product packaging bottle 11 can be moved by the third electric push rod 42 until Until the product packaged bottles 11 are at the top of the second conveyor belt 5, the arc-shaped buckle plate 45 is reset by the dual-axis motor 51 and the gear 52, and finally the fixing sleeve 43 and the semicircular sleeve plate 44 are reset again by the third electric push rod 42. At the same time, the third electric push rod 42 can detect whether all unqualified product packaged bottles 11 are at the top of the second conveyor belt 5. If there are unqualified product packaged bottles 11 at the top of the first conveyor belt 4, the second conveyor belt 5 will not start. Otherwise, the second conveyor belt 5 will start to move the unqualified product packaged bottles 11 away.

[0047] First, the user uses the vacuum pump 14 to evacuate the first vacuum box 12 and the second vacuum box 13 to a vacuum state, and observes the vacuum degree inside through the vacuum pressure display 15. After the sample product packaging bottle 11 to be tested is conveyed to the bottom end of the detection box 10 through a group of first conveyor belts 4, the second electric push rod 9 can be used to lower the detection box 10, so that the product packaging bottle 11 is inside the detection chamber 19, until the suction cup 22 contacts the top of the product packaging bottle 11, and at the same time, the suction cup 22 can continue to move upward under the action of pressure. At this time, the suction cup 22 can compress the spring 23, and then under the action of the spring 23's own rebound force, the bottom end of the suction cup 22 is tightly fitted with the top of the product packaging bottle 11, and then the first three-way solenoid valve 17 and The first solenoid valve 28 works. At this time, the air between the suction cup 22 and the product packaging bottle 11 enters the interior of the first vacuum box 12 through the fourth connecting pipe 27, the second connecting pipe 18 and the first connecting pipe 16, thereby slightly reducing the vacuum degree inside the first vacuum box 12, and at the same time reducing the air pressure inside the suction cup 22. Under the action of the external atmospheric pressure, the product packaging bottle 11 is sucked by the suction cup 22, and the second electric push rod 9 is used to move the detection box 10 upward until the bottom end of the limiting ring 24 is in contact with the inner wall of the bottom end of the limiting groove 21. At this time, the limiting ring 24 and the limiting groove 21 can limit the movement of the suction cup 22, and then the product packaging bottle 11 can be lifted by the suction cup 22, and the first electric push rod 8 can be used to move the movable plate 6 on the surface of the slide bar 7. The surface slides, and the second electric push rod 9 is driven to move by the moving plate 6, and the detection box 10, the suction cup 22 and the product packaging bottle 11 are driven to move by the second electric push rod 9 until the product packaging bottle 11 moves to the top of the bottom plate 36. At this time, the detection box 10 and the product packaging bottle 11 are moved down by the second electric push rod 9, so that the product packaging bottle 11 is respectively at the top of the pressure sensor 38. At this time, the first three-way solenoid valve 17 is operated again to allow outside air to enter the first connecting pipe 16, and at the same time, the first connecting pipe 16 at one end of the first vacuum box 12 is closed. At this time, the suction cup 22 no longer tightly sucks the product packaging bottle 11, and the product packaging bottle 11 inside the detection chamber 19 can be detected by the pressure sensor 38. At this time, the second three-way solenoid valve 35 is operated At the same time, the second solenoid valve 33 with the product packaging bottle 11 inside the detection chamber 19 also works, and the seventh connecting pipe 34 is opened through the second three-way solenoid valve 35, and the sixth connecting pipe 32 is opened through the second solenoid valve 33. At this time, the second three-way solenoid valve 35, the seventh connecting pipe 34, the fifth connecting pipe 31, the sixth connecting pipe 32 and the second solenoid valve 33 can instantly reduce the internal air pressure of the detection chamber 19, and then the second three-way solenoid valve 35 and the second solenoid valve 33 are instantly closed, and the air pressure change inside the detection chamber 19 is detected by the air pressure detection sensor 39. If the air pressure inside the detection chamber 19 changes, the product packaging bottle 11 inside the corresponding detection chamber 19 is a sealed unqualified product, otherwise it is a qualified product. After the inspection is completed,The second three-way solenoid valve 35 is used to connect one end of the seventh connecting pipe 34 to the outside air. By opening the second solenoid valve 33, the internal pressure of the detection chamber 19 can be made the same as the external atmospheric pressure, thereby facilitating the second electric push rod 9 to drive the detection box 10 to move upward. At the same time, the first three-way solenoid valve 17 and the first solenoid valve 28 are used to make the suction cup 22 tightly suck the product packaging bottle 11 again. The second electric push rod 9 and the first electric push rod 8 are used to move the detection box 10 and the product packaging bottle 11 to the first conveyor belt 4 on the side of the second conveyor belt 5. Then, the first three-way solenoid valve 17 and the first solenoid valve 28 are used to make the suction cup 22 no longer tightly suck the product packaging bottle 11. Finally, the first electric push rod 8 and the second electric push rod 8 are used to Rod 9 resets the detection box 10 so that the next group of product packaging bottles 11 can be moved and inspected again. At the same time, the third electric push rod 42 corresponding to the unqualified product packaging bottle 11 works, and the fixed sleeve 43 and the semicircular sleeve plate 44 are moved to one side of the product packaging bottle 11 through the third electric push rod 42. Then the dual-axis motor 51 works, and the output end of the dual-axis motor 51 drives the two sets of gears 52 to rotate in the same direction at the same time. At this time, the arc-shaped gusset plate 45 is moved by the gear 52 and the tooth groove 50, and the arc-shaped gusset plate 45 can be guided by the arc-shaped slide groove 46 and the arc-shaped slide plate 47, so that the arc-shaped gusset plate 45 performs a circular motion, and the arc-shaped gusset plate 45 can be moved by the limit arc groove 48 and the limit block 49. The distance between the arc gusset plate 45 and the semicircular sleeve plate 44 is limited to prevent the arc gusset plate 45 from moving out of the semicircular sleeve plate 44. After the arc gusset plate 45 drives the limit block 49, it stops moving until one side of the limit block 49 fits into the inner wall of one end of the limit arc groove 48. At this time, the movement is stopped, and the fixed sleeve 43, the semicircular sleeve plate 44 and the product packaging bottle 11 can be moved by the third electric push rod 42 until the product packaging bottle 11 is at the top of the second conveyor belt 5. Then the arc gusset plate 45 is reset by the dual-axis motor 51 and the gear 52, and finally the fixed sleeve 43 and the semicircular sleeve plate 44 are reset again by the third electric push rod 42. At the same time, the third electric push rod 42 can detect whether all unqualified product packaging bottles 11 are at the top of the second conveyor belt 5. If an unqualified product packaged bottle 11 is located at the top of the first conveyor belt 4, the second conveyor belt 5 will not start. Instead, the second conveyor belt 5 will start to move the unqualified product packaged bottle 11 away. This device can automatically complete the inspection work and can also remove and move the unqualified product packaged bottle 11 separately, further facilitating the user's inspection work. This device is simple and convenient to operate, and does not require multiple people to operate, further reducing practical costs. At the same time, this device uses negative pressure to perform inspections, and judges the sealing performance based on the pressure changes. This will not cause any contamination or damage to the product packaged bottle 11, and can also improve the accuracy of the inspection, while also further reducing the user's usage and maintenance costs.

If the air pressure inside the detection chamber (19) changes, the product packaging bottle (11) inside the corresponding detection chamber (19) is a sealed unqualified product, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe (34) is connected to the outside air through the second three-way electromagnetic valve (35). By opening the second electromagnetic valve (33), the inside of the detection chamber (19) can be made the same as the outside atmospheric pressure; Step 5: Transfer again, through the first three-way solenoid valve (17) and the first solenoid valve (28), the suction cup (22) is again used to tightly suck the product packaging bottle (11), and the second electric push rod (9) and the first electric push rod (8) are used to move the detection box (10) and the product packaging bottle (11) to the first conveyor belt (4) on the side of the second conveyor belt (5), and then the first electric push rod (8) and the second electric push rod (9) are used to reset the detection box (10), and the next group of product packaging bottles (11) are inspected again; Step 6: Take away the unqualified product packaging bottle (11), detect the unqualified product packaging bottle (11) corresponding to the third electric push rod (42) to work, and move the fixed sleeve (43) and the semicircular sleeve plate (44) to one side of the product packaging bottle (11) through the third electric push rod (42), and then the dual-axis motor (51) works, and the arc buckle plate (45) is moved through the gear (52) and the tooth groove (50) until one side of the limit block (49) fits with the inner wall of one end of the limit arc groove (48), and then stops moving. The fixed sleeve (43), the semicircular sleeve plate (44) and the product packaging bottle (11) can be moved through the third electric push rod (42). Until the product packaged bottles (11) are at the top of the second conveyor belt (5), the arc-shaped buckle plate (45) is reset by the double-axis motor (51) and the gear (52), and finally the fixing sleeve (43) and the semicircular sleeve plate (44) are reset again by the third electric push rod (42). At the same time, the third electric push rod (42) can detect whether all unqualified product packaged bottles (11) are at the top of the second conveyor belt (5). If there are unqualified product packaged bottles (11) at the top of the first conveyor belt (4), the second conveyor belt (5) will not start. Otherwise, the second conveyor belt (5) will start to move the unqualified product packaged bottles (11) away.
