[0064] The technical solutions in the embodiments of the present application will be clearly and completely explained below with reference to the drawings.

[0065] Embodiment one

[0066] As shown in Figure 1, a seamless cylinder bottom forming device comprises a bearing mechanism 2, a rotating mechanism 3, a finishing mechanism 4 and a detection mechanism 5 arranged on a frame 1. Figures 1-13 The finishing mechanism 4 is used for removing the protrusions on the inner wall of the cylinder bottom 6, and comprises a turning assembly 41 arranged on the frame 1 and used for removing the protrusions in sequence from the outer circle to the inner circle of the inner bottom arc surface of the cylinder 6, an adjusting assembly 42 arranged on the turning assembly 41 and used for changing the turning angle, and a recycling assembly 43 arranged on the turning assembly 41 and used for collecting the waste chips.

[0067] The turning assembly 41 removes the protrusions in sequence from the outer circle to the inner circle of the inner bottom arc surface of the cylinder 6, the adjusting assembly 42 adjusts the turning angle of the turning assembly 41 at different positions of the inner bottom arc surface of the cylinder, and the recycling assembly 43 collects the waste chips removed by the turning of the inner bottom of the cylinder.

[0068] It should be noted that after the cylinder bottom is formed, the inner wall of the cylinder bottom is first finished and detected, and then the cylinder mouth is processed.

[0069] It is worth mentioning that in the process of removing the protrusions in sequence from the outer circle (outer edge) to the inner circle (middle part) of the inner bottom arc surface of the cylinder 6 by the turning tool 419, the radius of the circle where the turning tool 419 contacts the inner bottom arc surface of the cylinder 6 gradually decreases, in order to ensure that the turning tool 419 and the inner bottom arc surface of the cylinder 6 remain tangent, therefore, the inclination angle of the turning tool 419 needs to be adjusted in real time for turning.

[0070] It is also worth mentioning that the turning assembly 41 first identifies the inner bottom arc surface of the cylinder, and then turns the protrusions on the inner bottom arc surface of the cylinder, and does not turn the positions without protrusions, thereby reducing the mechanical damage to the inner bottom of the cylinder.

[0071]

[0072] ​In this embodiment, the trimming mechanism 4 and the detection mechanism 5 work together to automatically remove protrusions from the outer to the inner ring of the bottom arc surface of the gas cylinder, preventing any protrusions from being missed. They also adjust the turning angle of the cutting tool 419 in a timely manner, improving the turning effect, ensuring the smoothness of the bottom arc surface of the gas cylinder, and improving the forming effect of the bottom of the gas cylinder. On the other hand, they can detect whether the bottom of the gas cylinder is broken and mark and recycle broken gas cylinders to stop losses in time, reduce production costs, and improve the gas cylinder's factory qualification rate.

[0074] Furthermore, such as Figures 1-3 As shown, the supporting mechanism 2 is used to drive the gas cylinder to be loaded onto the rotating mechanism 3, and it includes:

[0075] Mounting base 21, which is slidably mounted on the frame 1, and a third drive unit 22 is provided on the frame 1 for driving the mounting base 21 to move horizontally;

[0076] Arc-shaped base 23, two of the arc-shaped bases 23 are symmetrically raised and lowered on the mounting base 21 and are used to support the gas cylinder;

[0077] Lifting slides 24, two of the lifting slides 24 are mounted on the mounting base 21 and are used to drive the arc-shaped base 23 to lift.

[0078] It should be noted that an existing linear motor is installed on the lifting slide 24 to drive the arc-shaped base 23 to lift.

[0079] It is worth mentioning that the third drive unit 22, the second drive unit 415, and the first drive unit 412 have the same structure. They all adopt the drive method of lead screw, threaded block and stepper motor, that is, the stepper motor drives the lead screw to rotate, and the lead screw drives the threaded block to move back and forth in a linear motion.

[0080] In this embodiment, the supporting mechanism 2 can automatically load the gas cylinder onto the rotating mechanism 3, ensuring accurate positioning and saving manpower.

[0081] In detail, the existing mechanical arm places the gas cylinder on the arc-shaped base 23, the linear motor on the lifting slide 24 drives the arc-shaped base 23 with the gas cylinder to rise to the designated position, the third driving unit 22 drives the arc-shaped base 23 with the gas cylinder to move horizontally, so that the bottom of the gas cylinder enters the sleeve 31 of the rotating mechanism 3, and the empty arc-shaped base 23 with the gas cylinder is lowered to reset, waiting for the next use.

[0082] Further, as shown in Figure 2 and Figures 4-7 , the rotating mechanism 3 is used for driving the gas cylinder to rotate, which comprises:

[0083] The sleeve 31 is rotationally arranged on the rack 1, and the inside thereof is matched with the bottom end of the gas cylinder, and the rack 1 is provided with a driving part 32 for driving the sleeve 31 to rotate;

[0084] The electric clamping jaw 33 is arranged on the sleeve 31 and is used for fixing the bottom end of the gas cylinder;

[0085] The sleeve 34 is rotationally arranged on the outer side wall of the mounting frame 411 and is used for abutting against the open end of the fixed gas cylinder;

[0086] The working port 35 is arranged on the outer side wall of the mounting frame 411 and is coaxially arranged with the sleeve 34, and the long rod 413 with the hollow disc 4192 and the annular collecting cover 435 enters the inside of the gas cylinder from the working port 35.

[0087] It should be noted that the driving part 32 adopts the existing driving motor.

[0088] It is worth mentioning that the structure and function of the electric clamping jaw 33 are both prior art, and will not be described in detail.

[0089] In the embodiment, the rotating mechanism 3 is arranged, which can drive the gas cylinder to rotate stably and facilitate the turning work of the inner bottom of the gas cylinder.

[0090] In detail, after the bearing mechanism 2 drives the sleeve 31 in the bottom of the gas cylinder, the electric clamping jaw 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 with the sleeve 34 to move horizontally, so that the sleeve 34 abuts against the open end of the fixed gas cylinder, the sleeve 34 and the sleeve 31 cooperate to clamp the entire gas cylinder, the driving part 32 drives the gas cylinder to rotate through the sleeve 31, and the turning assembly 41 performs the turning work on the inner bottom of the gas cylinder.

[0091] Further, as shown in Figure 2 and Figures 6-13 , the turning assembly 41 comprises:

[0092] The mounting frame 411 is slidingly arranged on the rack 1, and a first driving unit 412 is arranged on the rack 1 and used for driving the mounting frame 411 to move horizontally;

[0093] A long rod 413 is slidingly arranged inside the mounting frame 411, and a first clamping hole 414 is arranged at one end of the long rod 413; a second driving unit 415 is arranged on the mounting frame 411 and used for driving the long rod 413 to move horizontally;

[0094] A transmission rod 416 is hingedly arranged inside the first clamping hole 414 through a rotating shaft, and a second clamping hole 417 is arranged at one end of the transmission rod 416;

[0095] A mounting block 418 is hingedly arranged inside the second clamping hole 417 through a rotating shaft, and a turning tool 419 is arranged on the mounting block 418; a first visual detection unit 4191 is arranged on the mounting block 418;

[0096] A hollow disc 4192 is slidingly arranged on the long rod 413, and a vertical plate 4193 is liftingly arranged on the hollow disc 4192 through a sliding block; the other end of the long rod 413 is hingedly arranged on the vertical plate 4193;

[0097] A fixing disc 4194 is arranged on the long rod 413, and a first hydraulic piece 4195 used for driving the hollow disc 4192 to move is arranged on the fixing disc 4194.

[0098] It should be noted that the first visual detection unit 4191 and the second visual detection unit 523 have the same structure, and both adopt an existing illuminating lamp and a high-speed camera.

[0099] It is worth mentioning that the vertical plate 4193 is used to ensure that the transmission rod 416 can be turned to a horizontal state in the first clamping hole 414 of the long rod 413, so that the turning tool 419 can turn the middle position of the arc surface of the inner bottom 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.

[0100] It is also worth mentioning that, in order to achieve the effect of identifying first and then turning, when the first visual detection unit 4191 identifies the protrusions on the inner bottom arc surface of the gas cylinder, the second driving unit 415 drives the long rod 413 to move horizontally back with the turning tool 419 and the first visual detection unit 4191 on the mounting block 418, and when the protrusions on the inner bottom arc surface of the gas cylinder are identified, the second driving unit 415 drives the long rod 413 to move horizontally forward with the turning tool 419 and the first visual detection unit 4191 on the mounting block 418. The adjustment assembly 42 adjusts the inclination angle of the turning tool 419, so that the turning tool 419 turns the protrusions on the inner bottom arc surface of the gas cylinder.

[0101] In the embodiment, by setting the turning assembly 41 and the rotating mechanism 3 in cooperation, 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.

[0102] In detail, after the rotating mechanism 3 drives the gas cylinder to rotate, the second driving unit 415 drives the long rod 413 to enter the gas cylinder from the working port 35 with the turning tool 419 on the mounting block 418, so that the turning tool 419 approaches the outer circle of the inner bottom arc surface of the gas cylinder without contacting. The first visual detection unit 4191 identifies whether there are protrusions on the outer circle of the inner bottom arc surface of the gas cylinder. If there are, the second driving unit 415 continues to drive the long rod 413 to move forward with the turning tool 419 on the mounting block 418 to the position of the outer circle of the inner bottom arc surface of the gas cylinder, and the turning tool 419 removes the protrusions on the outer circle 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 move back with the turning tool 419 on the mounting block 418 by a specified distance, and then the first hydraulic part 4195 drives the hollow disc 4192 to move in the direction of the fixed disc 4194 by a specified distance, forcing the upright plate 4193 to drive one end of the transmission rod 416 to rise along the side of the hollow disc 4192 and drive the transmission rod 416 to rotate, so that the other end of the transmission rod 416 descends, i.e. 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 next outer circle of the inner bottom arc surface of the gas cylinder, and if there are, the protrusions are continuously removed. If there are not, the second driving unit 415 directly drives the long rod 413 to move back with the turning tool 419 on the mounting block 418 by a specified distance, and the first hydraulic part 4195 continues to drive the turning tool 419 on the mounting block 418 to descend through the hollow disc 4192, moving towards the inner circle of the inner bottom arc surface of the gas cylinder, until the transmission rod 416 rotates to the first clamping hole 414 of the long rod 413 to be in a horizontal state, thereby sequentially removing the protrusions from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder.

[0103] Further, as shown in Figures 9-13 , the adjustment assembly 42 comprises:

[0104] Gear 421, which is arranged inside the second clamping hole 417 through the rotating shaft, is synchronously rotated with the mounting block 418 through the transmission mode of the belt and pulley.

[0107] In detail, in the process that the turning tool 419 removes the protrusions from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder in sequence, the transmission rod 416 is rotated in sequence, the gear 421 on the transmission rod 416 is gradually moved along the arc-shaped rack 422, the arc-shaped rack 422 drives the gear 421 to rotate, the gear 421 drives the mounting block 418 to gradually rotate through the transmission mode of the belt and pulley, and the inclination angle of the turning tool 419 is adjusted to adapt to the turning angle of different positions from the outer circle to the inner circle of the inner bottom arc surface of the gas cylinder.

[0108] Further, as shown in the figure, Figures 9-11 the recycling assembly 43 comprises:

[0109] Hanger 431, which is arranged on the long rod 413, is provided with an eccentric wheel 432 on the hanger 431 through the rotating shaft, and the eccentric wheel 432 is synchronously transmitted with the rotating shaft of the transmission rod 416 through the transmission mode of the belt and pulley.

[0110] L-shaped hanger rod 433, which is arranged on the bottom plate 423 through the sliding rail, is hingedly provided with a limiting block 434 on the L-shaped hanger rod 433, and the limiting block 434 is slidingly matched on the circumferential surface of the eccentric wheel 432.

[0111] Annular collecting cover 435, which is arranged on one end of the L-shaped hanger rod 433, is arranged outside the mounting block 418.

[0112] In the embodiment, the recovery assembly 43 and the turning assembly 41 are matched, on the one hand, the turning generated scraps can be automatically collected, the scraps are difficult to clean and can scratch the inner wall of the gas cylinder to cause mechanical damage, and the smoothness of the inner wall of the gas cylinder is ensured; on the other hand, the annular collecting cover 435 can be dynamically adjusted horizontally with the movement of the turning tool 419, the annular collecting cover 435 is always outside the turning tool 419, all the scraps can be collected, and the scraps are prevented from falling into the gas cylinder.

[0113] In detail, in the process that the turning tool 419 removes the protrusions from the outer circle to the inner circle along the arc surface of the bottom of the gas cylinder, the transmission rod 416 rotates in sequence, and rotates the eccentric wheel 432 through the transmission mode of the belt and the belt pulley, the eccentric wheel 432 drives the annular collecting cover 435 to move horizontally through the limiting block 434 and the L-shaped hanger 433, so that the annular collecting cover 435 is always outside the turning tool 419, the annular collecting cover 435 collects the scraps generated by the turning of the turning tool 419, and the scraps are processed regularly and uniformly.

[0114] Further, as shown in Figures 5-11 The detection mechanism 5 is used for detecting whether the bottom of the gas cylinder is broken, and includes a water injection assembly 51 arranged on the hollow disc 4192 and an identification assembly 52 arranged on the sleeve 31.

[0120] The water leakage hole 517 is arranged on the outer wall of the abutting cylinder 34 in the circumferential direction, and the second water pump 518 is arranged on the water tank 513 and connected to the water return box 516 through a hose.

[0121] It is worth mentioning that the caliber of the working port 35 is smaller than the inner diameter of the gas cylinder, and when the wastewater in the gas cylinder is recovered, the wastewater will not overflow from the working port 35, ensuring that the wastewater flows from the leakage hole 517 of the stop cylinder 34 to the water recovery box 516.

[0122] Need to be explained, after the bottom of the gas cylinder is turned, the gas cylinder stops rotating, and the bottom of the gas cylinder is detected again, which can not only detect whether the bottom of the gas cylinder is cracked after forming, but also detect whether the turning work cracks the bottom of the gas cylinder, ensuring the air tightness of the bottom of the gas cylinder after turning.

[0123] It is also worth mentioning that the existing electromagnetic valve is arranged on the annular air bag 511 for deflating the annular air bag 511.

[0124] In the embodiment, the water injection assembly 51 is arranged, which can automatically inject water into the bottom of the gas cylinder and seal the inside of the gas cylinder to prevent water leakage, ensuring that the air tightness detection of the bottom of the gas cylinder can be carried out smoothly.

[0125] In detail, after the bottom of the gas cylinder is turned, the gas cylinder stops rotating, the second driving unit 415 directly drives the long rod 413 with the hollow disc 4192 to move back to a specified distance, the air pump 515 inflates the inside of the annular air bag 511 through the hose, the annular air bag 511 expands outward, and the expanded annular air bag 511 tightly abuts against the inner wall of the gas cylinder, thereby sealing the space between the hollow disc 4192 and the bottom of the gas cylinder. Then, the first water pump 514 delivers the water in the water tank 513 to the water injection hole 512 through the hose, and the water injection hole 512 fills the space between the hollow disc 4192 and the bottom of the gas cylinder with water. The recognition assembly 52 detects whether the bottom of the gas cylinder is waterlogged, thereby detecting whether the bottom of the gas cylinder is cracked. After the detection is completed, the annular air bag 511 is deflated to recover to the inside of the hollow disc 4192, and the wastewater in the inside of the gas cylinder flows from the leakage hole 517 of the outer wall of the stop cylinder 34 to the water recovery box 516. The second water pump 518 delivers the water in the water recovery box 516 to the water tank 513 through the hose for reuse.

[0126] Further, as shown in Figures 5-6 The recognition assembly 52 comprises:

[0127] A V-shaped plate 521 is arranged on the output shaft of the second hydraulic part 522, and a rotary motor for driving the second hydraulic part 522 with the V-shaped plate 521 to rotate is arranged in the sleeve 31;

[0128] A second visual detection unit 523 is arranged on one side of the V-shaped plate 521;

[0129] The marking pen 524 is provided on the other side of the V-shaped plate 521, and a third hydraulic component 525 is provided on the output shaft of the third hydraulic component 525.

[0130] In this embodiment, the identification component 52 can identify whether there is water leakage at the bottom of the gas cylinder, thereby determining the airtightness of the bottom of the gas cylinder.

[0131] In detail, after the water injection component 51 fills the space between the hollow plate 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 bottom of the gas cylinder. The rotary motor drives the V-shaped plate 521 to slowly rotate one revolution, so that the second visual detection unit 523 can identify in real time whether there is water leakage at the bottom of the gas cylinder. If there is water leakage, the third hydraulic component 525 drives the marking pen 524 to mark the water leakage position, so that it is convenient for manual identification of gas cylinders with unqualified bottoms.

For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0134] Furthermore, such as Figure 14 As shown, an anti-slip pad 25 is provided on the arc-shaped base 23. The anti-slip pad 25 is used to prevent the gas cylinder from slipping off the arc-shaped base 23 when the bearing mechanism 2 is carrying the gas cylinder.

[0135] Work process:

[0136] First, the existing robotic arm places the gas cylinder flat on the support mechanism 2. The support mechanism 2 then loads the gas cylinder onto the rotating mechanism 3. The rotating mechanism 3 drives the gas cylinder to rotate. The turning component 41 first identifies and then removes protrusions along the outer and inner rings of the inner bottom arc surface of the gas cylinder. The adjustment component 42 adjusts the turning angle of the turning component 41 at different positions on the inner bottom arc surface of the gas cylinder in real time. The recycling component 43 collects the waste chips that are turned 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 leakage at the outer bottom of the gas cylinder to determine whether the bottom of the gas cylinder is cracked. Cracked gas cylinders are marked. The water inside the gas cylinder is recycled.
