Description

Technical Field

[0001] This invention relates to the field of can marking technology, and in particular to a marking device for lighter fuel cans. Background Technology

[0002] Lighter fuel cans are containers used to store fuel in lighters, typically made of materials such as iron or copper. These materials offer good corrosion resistance and pressure resistance, ensuring fuel stability during storage and use. Metal fuel cans also usually have good sealing properties to prevent fuel leakage. Furthermore, to prevent counterfeiting, manufacturers mark the cans during the manufacturing process.

[0003] In existing fuel tank manufacturing processes, the shell is typically formed using a stamping machine. However, stamping machines require manual feeding and constant transfer to different processing stations during operation, resulting in low efficiency. Furthermore, the marking locations cannot be standardized. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing stamping machines, such as the need for manual feeding during use, the need for continuous transfer to different processing stations during processing, low efficiency, and inconsistent marking positions.

[0021] Beneficial effects:

[0022] In this invention, a lighter fuel can marking device is described. By using a motor to drive the rotating shaft to rotate, the magnetic block is smoothly rotated through the connecting block and connecting column, realizing the automatic picking and flipping of the can. The position of the can is monitored by a camera, and combined with the rotation of the rotating disk driven by a third motor, the can is automatically corrected to ensure that the can is in the correct position before marking, thereby improving the marking quality and avoiding the inconvenience and errors of manual operation.

[0023] In this invention, a lighter fuel can marking device is provided. Through the cooperation of a fourth motor, a synchronous pulley, a synchronous belt, and a support base, the lifting platform is raised and lowered smoothly, ensuring the stability of the can during the marking process, reducing the impact of vibration and shaking on the marking quality, and two cans can be placed on the lifting platform so that they can be expanded and marked separately, thereby reducing the number of operation steps.

[0024] In this invention, the lighter fuel can marking device automatically expands the edge of the lighter fuel can during the marking process through the ingenious cooperation of two edge-expanding blocks and springs, making it easier to add a cap later. After resetting, the edge-expanding blocks can automatically reset under the force of the springs, avoiding affecting the conveying of the can and making it more convenient to use.

[0025] In this invention, by integrating components such as a conveyor, a turning mechanism, a material platform, a correction mechanism, a mounting plate, a gripper cylinder, an expansion block, a marking block, and a lifting mechanism, a fully automated process from conveying to marking of lighter fuel canisters is realized, which significantly improves production efficiency. The fully automated operation reduces manual intervention, lowers human error, and enhances the stability and reliability of the production line. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1

[0038] Reference Figures 1-8 A marking device includes components such as a conveyor 1, a base 3, a tilting mechanism, a material platform 37, a mounting plate 9, a mounting base 11, and a lifting mechanism. The conveyor 1 is installed on one side of the base 3 for transporting lighter fuel canisters to be marked. The base 3 serves as the supporting foundation for the entire device, on which various functional components are mounted.

[0039] The conveyor 1 is equipped with two baffles 2, which are located on both sides of the tank. They are used to limit the movement of the tank during the transport process, ensuring that the tank remains stable and does not shift or tip over.

[0040] The tilting mechanism includes two support frames 4, which are fixedly mounted on one side of the base 3. A common rotating shaft 13 is rotatably connected between the two support frames 4, and a connecting block 14 is fixedly fitted onto the outer wall of the rotating shaft 13. Four connecting posts 15 are fixedly mounted on the outer wall of the connecting block 14, and a magnet 16 is fixedly installed at the end of each connecting post 15 for attracting and receiving the can. The top of the magnet 16 is flush with the material platform 37 to ensure that the can is smoothly transferred from the tilting mechanism to the material platform 37.

[0041] To achieve the flipping function, a first motor 17 is fixedly installed on one side of one of the support frames 4, and the output end of the first motor 17 is fixedly connected to the rotating shaft 13. When the first motor 17 is started, it drives the rotating shaft 13 to rotate, which in turn drives the connecting block 14, the connecting column 15 and the magnet block 16 to rotate as a whole, thereby achieving the flipping of the tank.

[0042] A material platform 37 is fixedly mounted on top of the base 3 to support and position the can to be marked. A camera 6 is located on one side of the base 3, and the camera 6 works in conjunction with a correction mechanism on the material platform 37. The correction mechanism works by capturing image information of the can using the camera 6, comparing it with a preset standard position, and then driving the correction mechanism to fine-tune the can to ensure accurate marking. It includes a rotating disk 38 mounted on top of the material platform 37. The top of the rotating disk 38 is flush with the top of the material platform 37 to ensure the can is placed stably on the rotating disk 38.

[0043] A third motor 39 is fixedly installed on the top of the base 3. The output end of the third motor 39 is fixedly connected to the rotating disk 38 and is used to drive the rotating disk 38 to rotate.

[0044] Camera 6 is located on one side of the rotating disk 38 and is used to capture image information of the can. When the can is placed on the rotating disk 38, the third motor 39 is started and drives the rotating disk 38 to rotate. Camera 6 captures image information of the can in real time and compares it with a preset standard position. If a large deviation in the position of the can is found, the position of the can can be corrected by controlling the rotation speed and direction of the third motor 39.

[0045] The conveying mechanism includes two fixed seats 23 mounted on top of the base 3. Two first sliding rods 7 are slidably mounted through one side of one fixed seat 23 and are fixedly connected to the base 3. The other fixed seat 23 is fixedly sleeved on the two first sliding rods 7 and slidably connected to the base 3. Clamping components for holding the can are provided on the two first sliding rods 7. These clamping components may include multiple second clamping plates 30 and first clamping plates 29. These clamping plates open and close in a certain way to clamp or release the can. The clamping components are an important part of the marking equipment, used to clamp the can during transmission to ensure its stability. Specific implementation details are as follows:

[0046] Two rotating rods 25 are rotatably mounted on the two first sliding rods 7. These two rotating rods 25 can rotate freely on the first sliding rods 7 to adapt to clamping requirements at different angles.

[0047] Inside the two rotating rods 25, a flip bar 8 is fixedly installed. Multiple second clamping plates 30 and first clamping plates 29 are evenly distributed on the flip bar 8. The number and position of these clamping plates are designed according to the size and shape of the tank to ensure that the tank can be firmly clamped.

[0048] To drive the rotating rod 25 and the tilting bar 8 to tilt and rotate, thereby clamping and releasing the can, two connecting seats 24 are rotatably sleeved on the outer walls of the two first sliding rods 7. The rotating rod 25 is located inside the connecting seat 24 and is rotatably connected to it.

[0049] A second sliding rod 31 is slidably mounted on the top of the connecting seat 24. A third cylinder 32 is fixedly mounted through the second sliding rod 31. Rotating seats 33 are rotatably mounted on the two output ends of the third cylinder 32, and these rotating seats 33 are fixedly connected to the corresponding rotating rods 25. When the third cylinder 32 is working, its output end pushes or pulls the rotating seats 33, thereby causing the rotating rods 25 and the tilting bars 8 to tilt, thereby clamping and releasing the can.

[0050] A second motor 28 is also provided on the base 3, and the output end of the second motor 28 is connected to one of the fixed seats 23. When the second motor 28 is started, it drives the fixed seat 23 to move back and forth along the first sliding rod 7, thereby driving multiple second clamping plates 30 and the first clamping plate 29 to move together, realizing the conveying and clamping of the tank. On the top of the fixed seat 23 on one side, a first connecting rod 26 is rotatably provided. The other end of the first connecting rod 26 is rotatably provided with a second connecting rod 27, and the other end of the second connecting rod 27 is fixedly sleeved on the output end of the second motor 28.

[0051] When the second motor 28 starts, its output will drive the second connecting rod 27 to rotate. Since the first connecting rod 26 and the second connecting rod 27 are rotatably connected, the rotational motion of the second connecting rod 27 will be converted into the reciprocating motion of the first connecting rod 26.

[0052] The reciprocating movement of the first link 26 will drive the fixed base 23 connected to it, as well as the first sliding rod 7 and the clamping member on it, to reciprocate, thereby realizing the transfer of the tank.

[0053] Mounting plate 9 is fixedly mounted on one side of base 3, and a gripper cylinder 22 is provided at its bottom. Each of the two gripper blocks of gripper cylinder 22 is provided with expansion blocks 10, which are used for expanding the tank.

[0054] Mounting base 11 is disposed on one side of base 3, and two guide rods 34 are fixedly installed inside it. A marking block 35 is slidably mounted on the two guide rods 34, and the marking block 35 has marking protrusions. A first cylinder 12 is fixedly installed on one side of mounting base 11, and the output end of the first cylinder 12 passes through one side of mounting base 11 and is fixedly connected to the marking block 35. When the first cylinder 12 is activated, it drives the marking block 35 to slide along the guide rods 34 to the designated position for marking operation.

[0055] In addition, the bottom of the mounting base 11 is also fixedly provided with a first guide post 36 that works in conjunction with the marking block 35, which is used to limit and position the tank to ensure the accuracy of the marking position.

[0056] The specific structure of the lifting mechanism can be designed according to actual conditions. After the tank is transported onto the material platform 37 and positioned, the lifting mechanism will move the tank upward to a position that cooperates with the expansion block 10 and the marking block 35. Then, the gripper cylinder 22 will be activated to cause the expansion block 10 to expand the tank. At the same time, the marking block 35, driven by the first cylinder 12, will mark the tank on the other side. After marking is completed, the lifting mechanism will then move the tank back to its original position to await the next operation.

[0057] The lifting mechanism is used to move the can on the material platform 37 up and down so as to cooperate with the marking equipment. The specific implementation method is as follows:

[0058] A support bar 41 is slidably provided through the top of the base 3. The support bar 41 serves as the main support component of the lifting mechanism, and a lifting seat 40 is slidably provided through its top.

[0059] A fourth motor 42 is fixedly installed on the top of the base 3. Both the output end of the fourth motor 42 and the inner wall of one side of the base 3 are equipped with synchronous pulleys 43. The outer walls of the two synchronous pulleys 43 are connected by the same synchronous belt 44. When the fourth motor 42 starts, its output end drives one synchronous pulley 43 to rotate, which in turn drives the other synchronous pulley 43 to rotate synchronously via the synchronous belt 44.

[0060] A support base 45 is fixedly provided on one side of the synchronous belt 44, and the top of the support base 45 is fixedly connected to the support bar 41. Therefore, when the synchronous belt 44 moves, it will drive the support base 45 and the support bar 41 to move up and down together. This will enable the lifting seat 40 to move up and down.

[0061] This application can be used in the field of tank marking, or in other fields applicable to this application.

[0062] Example 2

[0063] refer to Figures 1-9 An improvement upon Embodiment 1: A marking device for lighter fuel cans, applied to the field of can marking, wherein a mounting bracket 5 is fixedly installed on one side of the base 3 by welding or bolting. The mounting bracket 5 is designed as a sturdy frame structure to ensure it can support the weight of the camera 6 and related components.

[0064] A connecting rod 18 is installed through the top of the mounting bracket 5. One end of the connecting rod 18 is fixed to the mounting bracket 5, and the other end is adjustablely fitted with an adjusting plate 19. The adjusting plate 19 is connected to the connecting rod 18 via a groove, threaded hole, or similar adjustable mechanism to adjust its position as needed.

[0065] Camera 6 is fixed to the adjusting plate 19 with bolts or other fastening methods, ensuring that the lens of camera 6 is aimed at the lighter fuel canister to be marked. At the same time, a controller 20 is set on the mounting bracket 5, and camera 6 is connected to controller 20 through wires to realize the transmission and processing of image data.

[0066] Two guide rails 21 are fixedly installed at the bottom of the mounting plate 9 by welding or bolting. The guide rails 21 should be installed parallel and securely on the mounting plate 9 to ensure that the gripper cylinder 22 can slide smoothly.

[0067] The gripper cylinder 22 is positioned between the two guide rails 21 and fixed to the mounting plate 9 by bolts or other fastening methods. Simultaneously, ensure that the sliding part of the gripper cylinder 22 fits well with the guide rails 21 to achieve smooth sliding motion.

[0068] The flaring mechanism includes a flaring block 46 fixedly mounted on the bottom of the mounting base 11, ensuring its stability and reliability. Then, the flaring block 46 is fixedly connected to the bottom of the first guide post 36 to provide guidance and support for the lifting movement of the lifting seat 40.

[0069] At the top of the lifting base 40, an expansion block 46 corresponding to the bottom expansion block 46 is provided, and its top is ensured to be flush with the lifting base 40. In this way, when the lifting base 40 is raised or lowered, the two expansion blocks 46 can move closer or further apart, thereby realizing the expansion operation of the lighter fuel canister.

[0070] Two second guide posts 47 are slidably installed through the top of the lifting seat 40, ensuring good fit with the sliding part of the lifting seat 40. The tops of both second guide posts 47 are fixedly connected to the top expansion block 46. Springs 48 are sleeved on the outer wall of the second guide posts 47, and the two ends of the springs 48 are fixedly connected to the bottom of the lifting seat 40 and the top of the connecting plate 49, respectively. In this way, when the lifting seat 40 rises and falls, the springs 48 can provide a certain degree of reset.

[0071] A wedge 50 is fixedly installed at the bottom of the marking block 35. The shape and size of the wedge 50 match those of the connecting plate 49. When the marking block 35 moves to mark, the wedge 50 at its bottom pushes the connecting plate 49 upward, which in turn causes the top expanding block 46 to move downward and expand the edge of the lighter fuel canister through the action of the second guide post 47 and the spring 48. After marking is completed, the spring 48 will drive the connecting plate 49 and the expanding block 46 to return to their original positions.

[0072] In this application, during use, the device is powered on, and the cans are placed sequentially on the conveyor 1. The conveyor 1 is then started for transport. When the cans come into contact with the corresponding magnets 16, they are magnetically attracted to the magnets 16. Then, the first motor 17 is started to drive the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 drives the connecting block 14 to rotate, which can adjust the position of the magnets 16 and cause the cans to flip, making the cans vertical. Then, the third cylinder 32 is activated to extend. The extension of the third cylinder 32 can drive the two rotating rods 25 to rotate on the first sliding rod 7, which can drive the corresponding two second clamping plates 30 and two... The first clamping plates 29 are far apart, while the third cylinder 32 can drive the second sliding rod 31 to move downward to avoid contact with the rotating rod 25. At the same time, the second motor 28 is started, which can drive the second connecting rod 27 to rotate. The rotation of the second connecting rod 27 can cooperate with the first connecting rod 26 to drive the fixed seat 23 to move back and forth. When the first clamping plate 30 moves onto the magnet block 16, the can is located between the two second clamping plates 30. The third cylinder 32 is started to retract, driving the two sets of rotating rods 25 to reset and rotate, driving the corresponding two second clamping plates 30 and two first clamping plates 29 to move closer to each other to clamp the can.

[0073] Then, the second motor 28 is started to drive the first sliding rod 7 to reset and move, which can move the can on the magnet block 16 to the material platform 37. The above operation is repeated to convey the can in sequence. When the can moves to the rotating disk 38, the camera 6 is started to detect it. When the camera 6 detects the marking position, the conveying continues. When the camera 6 does not detect the marking position, the third motor 39 is started to drive the rotating disk 38 to rotate. The rotation of the rotating disk 38 can drive the can to rotate until the camera 6 detects the marking position, and then the conveying continues.

[0074] When the adjusted tank moves onto the lifting seat 40, the fourth motor 42 is started to drive the synchronous pulley 43 to rotate. The rotation of the synchronous pulley 43 can drive the synchronous belt 44 to move. The movement of the synchronous belt 44 can drive the support bar 41 to move upward through the support seat 45. The upward movement of the support bar 41 can drive the lifting seat 40 to move upward, which can drive the tank to move upward. After the tank moves into place, both expansion blocks 10 are located inside the tank. The gripper cylinder 22 is started to drive the two expansion blocks 10 to move away from each other, which can expand the tank and change the tank from a circle to a rectangle. After the expansion is completed, the fourth motor 42 is started to rotate in the opposite direction, which drives the synchronous belt 44 to move in the opposite direction, which can drive the lifting seat 40 to reset through the support bar 41.

[0075] When the expanded tank is transported to the other side of the top of the lifting seat 40, the unexpanded tank moves onto the lifting seat 40, and the fourth motor 42 is started to drive the lifting seat 40 to move upward. The above actions are repeated to continue to expand the unexpanded tank. At the same time, the expanded tank is put onto the first guide post 36. At this time, the first cylinder 12 is started to extend, which can drive the marking block 35 to move. During the movement of the marking block 35, it can cooperate with the first guide post 36 to mark the tank.

[0076] During the upward movement of the tank, the top of the tank can be widened by the widening block 46 at the top of the first guide post 36. During the movement of the marking block 35, the connecting plate 49 can be moved upward by the wedge block 50. The upward movement of the connecting plate 49 can be widened by the first guide post 36 below the second guide post 47.

[0077] After marking is completed, the first cylinder 12 is activated to reset, and the edge-expanding block 46 can be reset and moved under the force of the spring 48. The fourth motor 42 is activated to rotate in the opposite direction to drive the lifting seat 40 to move downward, which in turn drives the marked can to move downward, and the marking is carried out in sequence.

[0078] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
