Description

Technical Field

[0001] This invention belongs to the field of bottle cap production and testing technology, specifically relating to a fully automatic quality inspection system for anti-counterfeiting caps of large water bottles. Background Technology

[0002] Bottled water, a common form of drinking water in modern life, has many advantages. Its sealed design prevents secondary contamination during transportation and storage, making it safer and more hygienic compared to bulk water or repeatedly boiled tap water. Bottled water is ready to drink immediately, eliminating the need for boiling or waiting for it to cool, making it suitable for quick access in homes, offices, schools, and other places, especially for emergency drinking water needs.

[0003] Bottled water is a common type of drinking water packaging. The anti-counterfeiting cap, as a core component, serves to seal and prevent counterfeiting; its quality directly affects drinking water safety and the user experience. Figures 2-4 As shown, our company's multi-functional anti-counterfeiting cap for large water dispensers includes a cap body. The top of the cap body has a push-out channel, and the bottom of the push-out channel has a top plate. The outer side of the top plate has pressure protrusions, and the connection point has a tear line. A pull ring is provided on the outer side of the push-out channel, which makes it easy to tear open the tear line to insert the straw when drinking water. The pressure protrusions are adapted to the water drinking scenario, helping the top tube of the water dispenser to trigger the tear, ensuring ease of use.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1As shown, this embodiment provides a fully automatic quality inspection system for anti-counterfeiting caps of large water bottles, including a cap loading assembly 1, an airtightness testing assembly 2, and a multi-functional strength testing assembly 3. The cap loading assembly 1 is used to load caps 4 in batches and drive them to rotate circumferentially and pass through the inspection station in sequence. The airtightness testing assembly 2 is located below the inspection station and is used to test the airtightness of the caps 4. The multi-functional strength testing assembly 3 is located above the inspection station and is used to test the top pressure strength of the ejection channel, the opening strength of the pull ring, and the compressive strength of the caps 4.

[0023] like Figures 2-4 As shown, the cap 4 is an anti-counterfeiting cap for large water bottles, including a cap body 41. The top of the cap body 41 has a bottle mouth engaging area 42 and an ejection channel 43. A pull ring 44 is installed on the outer side of the bottom plate of the ejection channel 43. A pressure protrusion 45 is provided on the outer side of the bottom plate of the ejection channel 43, which is located in the inner area of ​​the pull ring 44 and near the pull ring connection. A fragility line 46 is provided on the bottom plate of the ejection channel 43, which is located in the outer area of ​​the pull ring and near the pressure protrusion 45. An anti-detachment rib 47 is provided on the inner side of the bottom plate of the ejection channel 43, away from the pressure protrusion 45. An internal thread 48 is provided on the upper part of the inner cavity of the cap 4, and a sealing rib 49 is provided on the lower part of the inner cavity of the cap 4.

[0024] like Figure 5 As shown, the cap loading assembly 1 includes a loading base plate 11, a rotary driver 12, a turntable 13, bottle neck simulation components 14, an arc-shaped support plate 16, and a pressure ring 17. The loading base plate 11 is supported by the turntable 13 via the rotary driver 12. Several bottle neck simulation components 14 are mounted circumferentially on the turntable 13. An airtightness detection hole 15 is opened in the inner periphery of the bottle neck simulation components 14 on the turntable 13. An arc-shaped support plate 16 is fixed to the upper side of the loading base plate 11 at the periphery of the rotary driver 12. A pressure ring 17 is slidably sleeved on the outer side of the top of the arc-shaped support plate 16 on the lower side of the turntable 13.

[0025] like Figure 6 As shown, the bottle mouth simulation component 14 consists of an annular end plate 141, a bottle mouth simulation part 142, and anti-detachment buckles 143. The bottle mouth simulation part 142 is provided on the upper side of the annular end plate 141. The top of the bottle mouth simulation part 142 cooperates with the bottle mouth snap-fit ​​area 42. The outer side of the bottle mouth snap-fit ​​area 42 is provided with an external thread that cooperates with the internal thread 48. Multiple anti-detachment buckles 143 are provided circumferentially on the lower side of the annular end plate 141. The rotating turntable 13 and the annular end plate 141 are jointly snap-fitted with a sealing ring 18. Several sets of anti-detachment step grooves 19 that cooperate with the anti-detachment buckles 143 are provided on the rotating turntable 13.

[0026] The working principle of the cap loading assembly 1: The rotary driver 12 drives the turntable 13 to rotate at a constant speed, which drives the circumferentially arranged bottle mouth simulation components 14 to rotate synchronously, and delivers the fixed large water bottle anti-counterfeiting caps to each testing station in sequence; the bottle mouth simulation part 142 accurately matches the bottle mouth snapping area 42 of the cap 4 to complete the positioning and snapping, the sealing ring 18 achieves bottom sealing and plugging, and the anti-detachment buckle 143 and the anti-detachment step groove 19 cooperate to complete the stable positioning of the cap 4, preventing the cap 4 from shifting and shaking during the testing process; the arc-shaped support plate 16 and the pressure bearing ring 17 form a vertical load-bearing support for the turntable 13 to ensure that the overall structure does not deform during high pressure strength testing, and the air tightness testing hole 15 is reserved for ventilation channel to provide a ventilation testing path for the air tightness testing assembly 2 below.

[0027] like Figure 6 As shown, the airtightness testing assembly 2 includes an air pump 21, a hose 22, an air blowing head 23, an airtightness testing push rod 24, and a push plate 25. The air pump 21 and the airtightness testing push rod 24 are mounted on the material carrier base plate 11. The air supply end of the air pump 21 is connected to the air blowing head 23, which is embedded in the push plate 25, via the hose 22. The air blowing head 23 is located directly below the airtightness testing hole 15 at the testing station and is driven by the airtightness testing push rod 24 to move up and down with the push plate 25.

[0028] Working principle of air tightness testing component 2: The dynamic load release and reset mechanism 35 of the multi-functional strength testing component 3 drives the channel top pressure head 343 to move down until it touches the bottom plate of the ejection channel 43 and protects the easily broken line 46; the air tightness testing push rod 24 drives the push plate 25 and the air blowing head 23 to rise vertically, so that the air blowing head 23 is aligned with the air tightness testing hole 15 and fits and seals; the air pump 21 generates stable air pressure, and the test gas is introduced into the cap 4 through the hose 22 and the air blowing head 23. The sealing performance of the sealing rib 49 of the bottle mouth snap area 42 and the internal thread 48 is determined by the air pressure feedback value; after the test is completed, the air tightness testing push rod 24 drives the air blowing head 23 to fall back and reset, completing the air tightness testing process of a single set of cap 4.

[0029] like Figure 7 , Figure 11As shown, the multi-functional strength testing component 3 includes a lifting mechanism 31, a tilting mechanism 32, a hammer box 33, a combined dynamic load 34, a dynamic load release and reset mechanism 35, and a counterweight placement and removal mechanism 36. The combined dynamic load 34 is internally restricted by the sliding mechanism of the hammer box 33. The combined dynamic load 34 consists of a hammer base 341, a hammer rod 342, a channel pressing head 343, a cover stamping head 344, an iron plate 345, a counterweight block 346, and an inner ball-head plunger 347. The upper and lower sides of the hammer base 341 are respectively equipped with a channel pressing head 343 and a cover stamping head 344 via a hammer rod 342. An iron plate 345 is embedded in one side of the hammer base 341, and a counterweight block 346 positioned by an inner ball-head plunger 347 is snapped onto the other side of the hammer base 341. A dynamic load release and reset mechanism 35 is installed on the side of the hammer box 33 near the iron plate 345, and a counterweight picking and placing mechanism 36 is installed on the other side of the hammer box 33 for removing the counterweight block 346 from the hammer base 341 or placing the counterweight block 346 into the hammer base 341. The hammer box 33, the combined dynamic load 34, the dynamic load release and reset mechanism 35, and the counterweight picking and placing mechanism 36 together constitute the detection module. The flipping mechanism 32 is used to drive the detection module to flip around the horizontal line and to move along the horizontal line. The lifting mechanism 31 is used to drive the flipping mechanism 32 and the detection module to move vertically.

[0030] like Figure 8 As shown, the lifting mechanism 31 includes a strength detection push rod 311, a guide tube 312, and a carrier plate 313. The cylinder of the strength detection push rod 311 and the lower tube of the guide tube 312 are mounted on the upper side of the material carrier plate 11 and located in the inner perimeter area of ​​the rotary drive 12. The movable end of the strength detection push rod 311 and the upper tube of the guide tube 312 jointly support the carrier plate 313.

[0031] like Figure 9As shown, the tilting mechanism 32 includes a frame 321, a tilting motor 322, a drive gear 323, a straightening block 324, a driven gear ring 325, an axial push rod 326, a rotary joint 327, a support shaft 328, and a straightening joint tube 329. The frame 321 is mounted on the carrier plate 313. The tilting motor 322 is mounted on the lower part of the frame 321, and the straightening block 324 is rotatably supported on the upper part of the frame 321. The driven gear ring 325 is mounted on the outer side of the straightening block 324, and the drive gear 323, which meshes with the driven gear ring 325, is mounted on the output end of the tilting motor 322. An axial push rod 326 is mounted on one side of the frame 321 via a support plate. The movable end of the axial push rod 326 is connected to the support shaft 328 via the rotary joint 327. Keyways are symmetrically opened on the outer side of the support shaft 328. The center of the straightening block 324 has a through-shaft hole that mates with the support shaft 328, and the inner wall of the through-shaft hole is symmetrically provided with protruding keys that mate with the keyway. A straightening joint tube 329 is installed between the other side of the frame 321 and the dynamic load release and reset mechanism 35. The straightening joint tube 329 is composed of an axial sleeve and an axial protruding tube that can rotate and axially displace within it.

[0032] The working principle of the flipping mechanism 32: The flipping motor 322 meshes with the driven gear ring 325 through the active gear 323, driving the straightening block 324 and the overall detection module to complete a 180° flip, realizing the rapid switching of the pressure ends of the channel top pressure head 343 and the cover stamping head 344; the axial push rod 326 cooperates with the support shaft 328 to realize the lateral fine adjustment and alignment of the detection module; the design of the straightening section tube 329 is to improve the flipping stability.

[0033] like Figure 10 As shown, the hammer box 33 includes a box body 331. The inside of the box body 331 is provided with a rectangular sliding cavity 332. The side plate of the box body 331 near the dynamic load release and reset mechanism 35 is provided with a suction cup clearance groove 333. The side plate of the box body 331 near the counterweight removal and placement mechanism 36 is provided with a counterweight removal and placement port 334. The inner sides of the upper and lower plates of the box body 331 are equipped with protective pads 335. The upper and lower plates of the box body 331 and the protective pads 335 are provided with hammer rod clearance grooves 336.

[0034] The design principle of the hammer box 33 is as follows: the box body 331 provides vertical sliding limit space for the combined dynamic load 34, and the inner protective pad 335 plays the role of buffering, noise reduction and anti-collision; the counterweight loading and unloading port 334 facilitates the entry and exit of the counterweight block 346 for assembly, and the suction cup clearance groove 333 reserves the movement space for the electromagnetic suction cup 355 to adsorb and position; the hammer rod clearance groove 336 leaves room for the hammer rod 342 to move up and down, constraining the movement trajectory of the combined dynamic load 34 throughout the process, ensuring that the pressure process is a straight drop and the force is uniform and stable.

[0035] like Figures 12-13As shown, the outer diameter of the channel pressing head 343 is smaller than the inner diameter of the pull ring 44, and it can abut against the pressing protrusion 45 inside the pull ring 44 through vertical displacement; the channel pressing head 343 has a built-in micro motor 343a, and the output end of the micro motor 343a is equipped with a toggle gear 343b. The channel pressing head 343 is symmetrically provided with sliding grooves 343c on both sides of the toggle gear 343b. There are two pull ring hook plates 343d that mesh with the toggle gear 343b in the sliding grooves 343c.

[0036] In this embodiment, the outer diameter of the cap punching head 344 is larger than the outer diameter of the ejection channel 43, but smaller than the inner diameter of the bottle mouth latching area 42.

[0037] The working principle of the combined dynamic load 34: The hammer base 341 serves as the core load-bearing base, with the upper and lower ends fixed by the hammer rod 342 to the channel top pressure head 343 and the cover stamping head 344, respectively, adapting to two different pressure testing conditions; one side of the iron plate 345 is used to cooperate with the electromagnetic chuck 355 to achieve adsorption fixation and release drop, completing the dynamic load stamping test; the other side relies on the inner ball head plunger 347 to position and engage with the counterweight 346, realizing the quick addition and removal of the counterweight 346, thereby changing the overall dynamic load weight and switching between light and heavy pressure loads; in addition, the micro motor 343a inside the channel top pressure head 343 drives the actuating gear 343b to rotate, causing the pull ring hook plates 343d on both sides to extend outward synchronously, which can accurately hook the pull ring 44 of the cover 4, providing a clamping and pulling force structure for the pull ring 44 opening strength test.

[0038] like Figure 11 As shown, the hammer base 341 has an open storage cavity for storing the counterweight 346, and the inner ball plunger 347 is embedded in the inner wall of the open storage cavity; the outer side of the counterweight 346 has a positioning recess 346a that cooperates with the inner ball plunger 347, and the end face of the counterweight 346 has a locking groove 346b.

[0039] like Figure 14 As shown, the dynamic load release and reset mechanism 35 includes a slotted bracket 351, a lead screw motor 352, a lead screw 353, a movable block 354, and an electromagnetic chuck 355. The lead screw motor 352 is installed inside the slotted bracket 351, and the lead screw 353 is installed at the output end of the lead screw motor 352. The movable block 354, which restricts rotation, is sleeved on the outside of the lead screw 353. The electromagnetic chuck 355 is installed at the outer end of the movable block 354, and the outer end face of the electromagnetic chuck 355 is flush with the outer end face of the iron plate 345.

[0040] Working principle of dynamic load release and reset mechanism 35: The lead screw motor 352 drives the lead screw 353 to rotate, which drives the movable block 354 and the electromagnetic chuck 355 to move forward and fit precisely against the iron plate 345 of the hammer seat 341. After being powered on, the electromagnetic chuck 355 generates magnetic force to firmly attract the combined dynamic load 34, completing the lifting and energy storage. After reaching the designated detection height, the power is cut off and the magnetization is deactivated. The combined dynamic load 34 falls freely without restraint to complete the impact pressure test. After the test is completed, the lead screw 353 mechanism retracts and resets, and the electromagnetic chuck 355 attracts the combined dynamic load 34 again to complete the return to the original position, realizing automatic cycle of single test.

[0041] like Figure 15 As shown, the counterweight loading and unloading mechanism 36 includes a counterweight receiving box 361. The counterweight receiving box 361 has an external storage cavity 362 inside. A horizontal screw jack 363 is mounted on the outer end plate of the counterweight receiving box 361. A guide rod 364 passes through the outer end plate of the counterweight receiving box 361. The movable end of the horizontal screw jack 363 and the guide rod 364 jointly support a mechanical gripper 365. The mechanical gripper 365 has two locking claws that can extend into the locking groove 346b and lock or unlock it through relative displacement. An external ball-head plunger 366 is embedded in the inner wall of the external storage cavity 362 of the counterweight receiving box 361. The counterweight receiving box 361 is located at the periphery of the counterweight loading and unloading port 334. A reinforcing rib 367 is provided between the counterweight receiving box 361 and the box body 331.

[0042] The working principle of the counterweight loading and unloading mechanism 36: The horizontal screw jack 363 drives the mechanical gripper 365 to extend laterally. The mechanical gripper 365 locks into the locking groove 346b on the end face of the counterweight block 346 to complete the locking. With the help of the outer ball plunger 366, the positioning and clamping of the counterweight block 346 and the hammer seat 341 are released, and the counterweight block 346 is taken out from the combined dynamic load 34 and stored in the counterweight receiving box 361. Conversely, the counterweight block 346 can be pushed into the storage cavity of the hammer seat 341 in the reverse action. The inner ball plunger 347 is engaged in the positioning recess 346a to complete the automatic positioning and locking. The entire process of counterweight block 346 disassembly and assembly is completed automatically, and the load required for non-destructive testing and ultimate destructive testing can be quickly switched.

[0043] The overall testing process of the detection system in this embodiment is as follows: S1. The first cap 4 is transferred to the testing station. The dynamic load release and reset mechanism 35 of the multi-functional strength testing component 3 drives the channel top pressure head 343 to move down until it touches the bottom plate of the ejection channel 43 and protects the easily broken line 46. The air tightness testing component 2 ventilates to complete the air tightness test of the bottle mouth clamping area 42. S2. Transfer the second cover 4 to the testing station. The counterweight removal and placement mechanism 36 removes the counterweight block 346, and the dynamic load release and reset mechanism 35 releases the combined dynamic load 34 under light load, completing the first top pressure strength test of the ejection channel 43. It is required that the fragility line 46 of the ejection channel 43 will not be damaged. Reset the combined dynamic load 34, and the counterweight removal and placement mechanism 36 inserts the counterweight block 346. The combined dynamic load 34 under heavy load falls, completing the second top pressure strength test of the ejection channel 43. It is required that the fragility line 46 of the ejection channel 43 is damaged. This indicates that the top pressure strength of the ejection channel 43 is within the designed range.

[0044] S3. Transfer the third cover 4 to the testing station. The flipping mechanism 32 switches the cover stamping head 344. The counterweight loading and unloading mechanism 36 loads the counterweight block 346. The combined dynamic load 34 in heavy load state falls to complete the overall compressive strength test of the cover body 41. It is required that there is no obvious deformation. S4. The fourth cover 4 is transferred to the testing station. The dynamic load release and reset mechanism 35 of the multi-functional strength testing component 3 drives the channel top pressure head 343 to move down until it touches the bottom plate of the ejection channel 43. The channel top pressure head 343 extends the pull ring hook plate 343d, which is located on the lower side of the pull ring 44. The dynamic load release and reset mechanism 35 drives the pull ring 44 to be pulled up, thus completing the opening strength test of the pull ring 44.
