[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Embodiment 1 As Figures 1 - 13 shown, a seamless gas cylinder bottom forming device includes a carrying mechanism 2, a rotating mechanism 3, a trimming mechanism 4, and a detection mechanism 5 provided on a frame 1; The trimming mechanism 4 is used to remove the protrusions on the inner wall of the bottom of the gas cylinder 6, and includes a turning component 41 provided on the frame 1 and used to sequentially remove the protrusions from the outer circle to the inner circle along the inner bottom arc surface of the gas cylinder 6, an adjustment component 42 provided on the turning component 41 and used to change the turning angle, and a recovery component 43 provided on the turning component 41 and used to collect waste chips; The turning assembly 41 first identifies and then removes the protrusions from the outer circle to the inner circle along the arc surface of the inner bottom of the gas cylinder. The adjusting assembly 42 adjusts the turning angle of the turning assembly 41 at different positions on the arc surface of the inner bottom of the gas cylinder. The recycling assembly 43 collects the chips cut off from the inner bottom of the gas cylinder.

[0035] It should be noted that after the bottom of the gas cylinder is formed, the inner wall of the bottom of the gas cylinder is first trimmed and inspected, and then the mouth of the gas cylinder is processed and formed.

[0036] It is worth mentioning that during the process of the turning tool 419 sequentially removing the protrusions from the outer circle (outer edge) to the inner circle (middle part) of the arc surface of the inner bottom of the gas cylinder 6, the radius of the circle where the turning tool 419 contacts the arc surface of the inner bottom of the gas cylinder 6 gradually decreases. In order to ensure that the turning tool 419 remains tangent to the arc surface of the inner bottom of the gas cylinder 6, therefore, it is necessary to adjust the tilt angle of the turning tool 419 in real time for turning.

[0037] It is also worth mentioning that the turning assembly 41 first identifies the arc surface of the inner bottom of the gas cylinder, and then turns the positions on the arc surface of the inner bottom of the gas cylinder where there are protrusions, and does not turn the positions without protrusions, reducing the mechanical damage to the inner bottom of the gas cylinder.

[0038] In this embodiment, through the cooperation of the trimming mechanism 4 and the detection mechanism 5 provided, on the one hand, it can automatically remove the protrusions from the outer circle to the inner circle along the arc surface of the inner bottom of the gas cylinder, prevent the protrusions on the arc surface of the inner bottom of the gas cylinder from being missed, and can timely adjust the turning angle of the turning tool 419, improving the turning effect, ensuring the smoothness of the arc surface of the inner bottom of the gas cylinder, and improving the forming effect of the bottom of the gas cylinder; on the other hand, it can detect whether the bottom of the gas cylinder is cracked, mark and recycle the cracked gas cylinders, stop losses in time, reduce production costs, and has a high degree of automation, improving the passing rate of the gas cylinders leaving the factory.

[0039] Specifically, the existing robotic arm places the gas cylinder flat on the loading mechanism 2, the loading mechanism 2 loads the gas cylinder on the rotating mechanism 3, the rotating mechanism 3 drives the gas cylinder to rotate by itself, the turning assembly 41 first identifies and then removes the protrusions from the outer circle to the inner circle along the arc surface of the inner bottom of the gas cylinder, the adjusting assembly 42 adjusts the turning angle of the turning assembly 41 at different positions on the arc surface of the inner bottom of the gas cylinder in real time, the recycling assembly 43 collects the chips cut off from the inner bottom of the gas cylinder, the water injection assembly 51 injects water into the inner bottom of the gas cylinder, the identification assembly 52 detects whether the outer bottom of the gas cylinder leaks water to judge whether the bottom of the gas cylinder is cracked, marks the gas cylinders with cracked bottoms, and the water in the gas cylinders is recycled.

[0040] Further, as Figures 1 - 3 shown, the loading mechanism 2 is used to drive the gas cylinder to be loaded on the rotating mechanism 3, and it includes: Mounting base 21, the mounting base 21 is slidably arranged on the frame 1, and a third driving unit 22 is arranged on the frame 1, and the third driving unit 22 is used to drive the mounting base 21 to move horizontally; Arc-shaped base 23, two arc-shaped bases 23 are symmetrically arranged on the mounting base 21 in a lifting manner, and are used to support the gas cylinder; Lifting slide table 24, two lifting slide tables 24 are arranged on the mounting base 21, and are used to drive the arc-shaped base 23 to lift.

[0041] It should be noted that a conventional linear motor is arranged on the lifting slide table 24 to drive the arc-shaped base 23 to lift.

[0042] It is worth mentioning that the third driving unit 22, the second driving unit 415, and the first driving unit 412 have the same structure, and all adopt the driving mode of a lead screw, a threaded block, and a stepping motor, that is, the stepping motor drives the lead screw to rotate, and the lead screw drives the threaded block to reciprocate linearly.

[0043] In this embodiment, through the provided loading mechanism 2, the gas cylinder can be automatically loaded on the rotating mechanism 3, with accurate positioning and labor saving.

[0044] Specifically, the existing robotic arm places the gas cylinder flat on the arc-shaped base 23, the linear motor on the lifting slide table 24 drives the arc-shaped base 23 to rise with the gas cylinder to the specified position, and the third driving unit 22 drives the arc-shaped base 23 to move horizontally with the gas cylinder, so that the bottom end of the gas cylinder enters the sleeve 31 of the rotating mechanism 3, and the empty arc-shaped base 23 with the gas cylinder descends and resets for the next use.

[0045] Furthermore, as Figure 2 and Figures 4 - 7 shown, the rotating mechanism 3 is used to drive the gas cylinder to rotate itself, and it includes: Sleeve 31, the sleeve 31 is rotatably arranged on the frame 1, and its interior is adapted to the bottom end of the gas cylinder, and a driving member 32 for driving the sleeve 31 to rotate is arranged on the frame 1; Electric gripper 33, the electric gripper 33 is arranged on the sleeve 31 and is used to fix the bottom end of the gas cylinder; Bracing cylinder 34, the bracing cylinder 34 is rotatably arranged on the outer side wall of the mounting frame 411 and is used to brace and fix the open end of the gas cylinder; Working port 35, the working port 35 is opened on the outer side wall of the mounting frame 411 and is arranged coaxially with the bracing cylinder 34, and the long rod 413 brings the hollow disk 4192 and the annular collection cover 435 into the interior of the gas cylinder from the working port 35.

[0046] It should be noted that the driving member 32 adopts a conventional driving motor.

[0047] It is worth mentioning that the structure and function of the electric gripper 33 are both prior arts and will not be elaborated herein.

[0048] In this embodiment, by providing the rotating mechanism 3, the gas cylinder can be driven to rotate by itself, with stable rotation, facilitating the turning work on the inner bottom of the gas cylinder.

[0049] Specifically, after the bearing mechanism 2 drives the bottom sleeve 31 of the gas cylinder, the electric gripper 33 clamps and fixes the bottom end of the gas cylinder. The first driving unit 412 of the turning assembly 41 drives the mounting frame 411 to move horizontally with the abutting cylinder 34, so that the abutting cylinder 34 abuts against and fixes the opening end of the gas cylinder. The abutting cylinder 34 and the sleeve 31 cooperate to clamp the whole gas cylinder. The driving part 32 drives the gas cylinder to rotate by itself through the sleeve 31, and then the turning assembly 41 performs turning work on the inner bottom of the gas cylinder.

[0050] Further, as Figure 2 and Figures 6 - 13 shown, the turning assembly 41 includes: A mounting frame 411, which is slidably arranged on the frame 1. A first driving unit 412 is arranged on the frame 1, and this first driving unit 412 is used to drive the mounting frame 411 to move horizontally; A long rod 413, which is slidably arranged inside the mounting frame 411. A first clamping hole 414 is opened at one end of the long rod 413. A second driving unit 415 is arranged on the mounting frame 411, and this second driving unit 415 is used to drive the long rod 413 to move horizontally; A transmission rod 416, which is hingedly arranged inside the first clamping hole 414 through a rotating shaft. A second clamping hole 417 is opened at one end of the transmission rod 416; A mounting block 418, which is hingedly arranged inside the second clamping hole 417 through a rotating shaft. A turning tool 419 is arranged on the mounting block 418, and a first visual detection unit 4191 is arranged on the mounting block 418; A hollow disk 4192, which is slidably arranged on the long rod 413. A vertical plate 4193 is arranged on the hollow disk 4192 through a slider for lifting. The other end of the long rod 413 is hingedly arranged on the vertical plate 4193; A fixed disk 4194, which is arranged on the long rod 413. A first hydraulic part 4195 for driving the hollow disk 4192 to move is arranged on the fixed disk 4194.

[0051] It should be noted that the structures of the first visual detection unit 4191 and the second visual detection unit 523 are the same, and both adopt existing lighting lamps and high-speed cameras.

[0052] It is worth mentioning that the function of the vertical plate 4193 is to ensure that the transmission rod 416 can be rotated into the first clamping hole 414 of the long rod 413 and be in a horizontal state, which is convenient for the turning tool 419 to turn the middle position of the inner bottom arc surface of the gas cylinder. At this time, the top of the vertical plate 4193 also rises into the first clamping hole 414 of the long rod 413.

[0053] It is also worth mentioning that in order to achieve the effect of first identifying and then turning, when the first vision detection unit 4191 identifies the protrusion on the inner bottom arc surface of the gas cylinder, the second driving unit 415 drives the long rod 413 to horizontally move back with the turning tool 419 and the first vision detection unit 4191 on the mounting block 418. After identifying the protrusion on the inner bottom arc surface of the gas cylinder, the second driving unit 415 then drives the long rod 413 to horizontally move forward with the turning tool 419 and the first vision detection unit 4191 on the mounting block 418, and the adjusting assembly 42 adjusts the inclination angle of the turning tool 419 so that the turning tool 419 turns the protrusion on the inner bottom arc surface of the gas cylinder.

[0054] In this embodiment, by setting the turning assembly 41 to cooperate with the rotating mechanism 3, the protrusions can be automatically removed in sequence from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder, preventing the protrusions on the inner bottom arc surface of the gas cylinder from being missed.

[0055] Specifically, after the rotating mechanism 3 drives the gas cylinder to rotate, the second driving unit 415 drives the long rod 413 to bring the turning tool 419 on the mounting block 418 into the gas cylinder from the working port 35, so that the turning tool 419 approaches the outer ring of the inner bottom arc surface of the gas cylinder without touching it. The first visual detection unit 4191 identifies whether there are protrusions on the outer ring of the inner bottom arc surface of the gas cylinder. If so, the second driving unit 415 continues to drive the long rod 413 to bring the turning tool 419 on the mounting block 418 forward to the position of the outer ring of the inner bottom arc surface of the gas cylinder, and the turning tool 419 removes the protrusions on the outer ring of the inner bottom arc surface of the gas cylinder. After removing the protrusions, the second driving unit 415 drives the long rod 413 to bring the turning tool 419 on the mounting block 418 back a specified distance. Then, the first hydraulic component 4195 drives the hollow disc 4192 to move a specified distance in the direction of the fixed disc 4194, forcing the vertical plate 4193 to drive one end of the transmission rod 416 to rise along the side surface of the hollow disc 4192 and drive the transmission rod 416 to rotate, so that the other end of the transmission rod 416 descends, that is, the turning tool 419 on the mounting block 418 descends. The first visual detection unit 4191 continues to identify whether there are protrusions on the second outer ring of the inner bottom arc surface of the gas cylinder. If so, continue to remove them. If not, the second driving unit 415 directly drives the long rod 413 to bring the turning tool 419 on the mounting block 418 back a specified distance, and the first hydraulic component 4195 continues to drive the turning tool 419 on the mounting block 418 to descend through the hollow disc 4192 and move towards the inner ring of the inner bottom arc surface of the gas cylinder until the transmission rod 416 rotates into the first clamping hole 414 of the long rod 413 and is in a horizontal state, so as to remove the protrusions in sequence from the outer ring to the inner ring of the inner bottom arc surface of the gas cylinder.

[0056] Further, as Figures 9 - 13 shown, the adjusting assembly 42 includes: a gear 421, the gear 421 is rotatably arranged inside the second clamping hole 417 through a rotating shaft, and the gear 421 rotates synchronously with the mounting block 418 through the transmission mode of a belt and a pulley; an arc-shaped rack 422, the arc-shaped rack 422 is arranged inside the first clamping hole 414 through a bottom plate 423 and is used to drive the gear 421 to rotate, and the bottom plate 423 is arranged at the bottom of the long rod 413.

[0057] In this embodiment, by setting the adjusting assembly 42, the turning angle of the turning tool 419 can be adjusted in time to ensure that the turning tool 419 is tangent to the inner bottom arc surface of the gas cylinder 6, ensuring the smoothness of the inner bottom arc surface of the gas cylinder and improving the forming effect of the bottom of the gas cylinder.

[0058] Specifically, during the process of the turning tool 419 removing the protrusions in sequence from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder, the transmission rod 416 rotates in sequence, causing the gear 421 on the transmission rod 416 to gradually move along the arc-shaped rack 422. The arc-shaped rack 422 drives the gear 421 to rotate, and the gear 421 drives the mounting block 418 to gradually rotate through the transmission mode of the belt and pulley, thereby adjusting the inclination angle of the turning tool 419 to adapt to the turning angles at different positions from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder.

[0059] Further, as Figures 9 - 11 shown, the recovery assembly 43 includes: A hanger 431, which is arranged on the long rod 413. An eccentric wheel 432 is rotatably arranged on the hanger 431 through a rotating shaft, and the eccentric wheel 432 is synchronously driven with the rotating shaft of the transmission rod 416 through the transmission mode of the belt and pulley; An L-shaped suspension rod 433, which is slidably arranged on the bottom plate 423 through a slide rail. A limit block 434 is hinged on the L-shaped suspension rod 433, and the limit block 434 is slidably matched with the circumferential side surface of the eccentric wheel 432; An annular collection cover 435, which is erected at one end of the L-shaped suspension rod 433, and the annular collection cover 435 surrounds the outside of the mounting block 418.

[0060] In this embodiment, by the cooperation of the set recovery assembly 43 and the turning assembly 41, on the one hand, it can automatically collect the waste chips generated by turning, avoiding the waste chips directly falling into the gas cylinder and being difficult to clean. When cleaning, the waste chips are easy to scratch the inner wall of the gas cylinder and cause mechanical damage, ensuring the smoothness of the inner wall of the gas cylinder; on the other hand, the annular collection cover 435 can horizontally and dynamically adjust its position as the turning tool 419 moves, ensuring that the annular collection cover 435 always surrounds the outside of the turning tool 419, and can collect all the waste chips, avoiding the waste chips from falling into the interior of the gas cylinder.

[0061] Specifically, during the process of the turning tool 419 removing the protrusions in sequence from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder, the transmission rod 416 rotates in sequence and drives the eccentric wheel 432 to rotate through the transmission mode of the belt and pulley. The eccentric wheel 432 drives the annular collection cover 435 to move horizontally through the limit block 434 and the L-shaped suspension rod 433, so that the annular collection cover 435 always surrounds the outside of the turning tool 419. The annular collection cover 435 collects the waste chips generated by the turning of the turning tool 419 and performs unified processing at regular intervals.

[0062] Further, as Figures 5 - 11 shown, the detection mechanism 5 is used to detect whether the bottom of the gas cylinder is cracked, and it includes a water injection assembly 51 arranged on the hollow disk 4192 and an identification assembly 52 arranged on the sleeve 31; The water injection assembly 51 includes: An annular airbag 511 disposed on the outer wall of the hollow disk 4192, which is used to abut against the inner wall of the gas cylinder after inflation; A water injection hole 512 disposed on one side of the hollow disk 4192 close to the turning tool 419; A water tank 513 disposed on the mounting frame 411. A first water pump 514 is provided on the water tank 513. The first water pump 514 transports the water in the water tank 513 to the water injection hole 512 through a hose. An air pump 515 is provided on the water tank 513. The air pump 515 is connected to the annular airbag 511 through a hose; A water return box 516 disposed on the outer wall of the mounting frame 411 and located directly below the working port 35. The water return box 516 is used to temporarily store the waste water flowing out of the gas cylinder; Leakage holes 517. Several groups of the leakage holes 517 are formed on the outer wall of the abutting cylinder 34 along the circumferential direction. A second water pump 518 is provided on the water tank 513. The second water pump 518 transports the water in the water return box 516 to the water tank 513 through a hose.

[0063] It is worth mentioning that the diameter of the working port 35 is smaller than the inner diameter of the gas cylinder. When recovering the waste water in the gas cylinder, the waste water will not overflow from the working port 35, ensuring that the waste water flows from the leakage holes 517 of the abutting cylinder 34 into the water return box 516.

[0064] It should be noted that after turning the inner bottom of the gas cylinder, the gas cylinder stops self-rotating, and then the bottom of the gas cylinder is detected. This can not only detect whether cracks occur in the bottom of the gas cylinder after forming, but also detect whether the turning work causes cracks in the bottom of the gas cylinder, ensuring the airtightness of the bottom of the gas cylinder after turning work.

[0065] It is also worth mentioning that an existing solenoid valve is provided on the annular airbag 511 for deflating the annular airbag 511.

[0066] In this embodiment, by providing the water injection assembly 51, water can be automatically injected into the inner bottom of the gas cylinder, and the inside of the gas cylinder can be sealed to prevent water leakage, ensuring the smooth progress of the airtightness detection of the bottom of the gas cylinder.

[0067] Specifically, after turning the inner bottom of the gas cylinder, the gas cylinder stops self-rotating. The second driving unit 415 directly drives the long rod 413 to move the hollow disk 4192 back to a specified distance. The air pump 515 inflates the inside of the annular airbag 511 through a hose. The annular airbag 511 expands outwards. After expansion, the annular airbag 511 tightly abuts against the inner wall of the gas cylinder, thus closing the space between the hollow disk 4192 and the bottom of the gas cylinder. Then, the first water pump 514 transports the water in the water tank 513 to the water injection hole 512 through a hose. The water injection hole 512 fills the space between the hollow disk 4192 and the bottom of the gas cylinder with water. The identification component 52 detects whether there is water seepage on the outer bottom of the gas cylinder, so as to detect whether cracks occur at the bottom of the gas cylinder. After the detection is completed, the annular airbag 511 deflates and returns to the inside of the hollow disk 4192. The waste water inside the gas cylinder flows into the water return box 516 through the water leakage holes 517 on the outer wall of the abutting cylinder 34. The second water pump 518 transports the water in the water return box 516 to the water tank 513 through a hose for reuse.

[0068] Further, as Figures 5 - 6 shown, the identification component 52 includes: A V-shaped plate 521. A second hydraulic component 522 is rotatably arranged inside the sleeve 31. The V-shaped plate 521 is arranged on the output shaft of the second hydraulic component 522. A rotating motor for driving the second hydraulic component 522 to drive the V-shaped plate 521 to rotate is arranged inside the sleeve 31; A second vision detection unit 523. The second vision detection unit 523 is arranged on one side surface of the V-shaped plate 521; A marking pen 524. A third hydraulic component 525 is arranged on the other side surface of the V-shaped plate 521. The marking pen 524 is arranged on the output shaft of the third hydraulic component 525.

[0069] In this embodiment, through the arranged identification component 52, it is possible to identify whether there is water seepage on the outer bottom of the gas cylinder, so as to judge the airtightness of the bottom of the gas cylinder.

[0070] Specifically, after the water injection component 51 fills the space between the hollow disk 4192 and the bottom of the gas cylinder with water, the second hydraulic component 522 drives the V-shaped plate 521 to move forward into the concave arc surface of the outer bottom of the gas cylinder. The rotating motor drives the V-shaped plate 521 to slowly rotate one circle by itself, so that the second vision detection unit 523 can identify in real time whether there is water seepage on the outer bottom of the gas cylinder. If there is water seepage, the third hydraulic component 525 drives the marking pen 524 to mark at the water seepage position, which is convenient for manual identification of the gas cylinders with unqualified bottoms.

[0071] Embodiment Two As Figure 14 shown, the same or corresponding components as those in Embodiment One are marked with the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in: Furthermore, as Figure 14 shown, an anti-slip pad 25 is provided on the arc-shaped base 23. The function of the anti-slip pad 25 is to prevent the gas cylinder from slipping off the arc-shaped base 23 when the carrying mechanism 2 transports the gas cylinder.

[0072] Working process: First, the existing robotic arm places the gas cylinder flat on the carrying mechanism 2. The carrying mechanism 2 loads the gas cylinder onto the rotating mechanism 3. The rotating mechanism 3 drives the gas cylinder to rotate by itself. The turning component 41 first identifies and then removes the protrusions from the outer circle to the inner circle along the arc surface of the inner bottom of the gas cylinder. The adjusting component 42 adjusts the turning angle of the turning component 41 at different positions on the arc surface of the inner bottom of the gas cylinder in real time. The recycling component 43 collects the waste chips cut off from the inner bottom of the gas cylinder. The water injection component 51 injects water into the inner bottom of the gas cylinder. The identification component 52 detects whether there is water seepage on the outer bottom of the gas cylinder to determine whether the bottom of the gas cylinder is cracked, and marks the gas cylinder with a cracked bottom. The water in the gas cylinder is recycled.
