Gas cylinder processing inner and outer cleaning inner wall crack automatic detection equipment

Abstract

This invention relates to the field of gas cylinder processing, and more particularly to an automatic detection device for internal wall cracks in gas cylinders after internal and external cleaning. The technical problem is that when manually inspecting the inner wall of a gas cylinder, it is difficult to align the flexible lamp with the narrow nozzle and insert it. Furthermore, even after the lamp is inserted, the remaining gap at the nozzle is small, making it difficult to spot defects by visual inspection alone. This allows potentially defective cylinders to flow into subsequent processes, affecting product quality. The technical solution is an automatic detection device for internal wall cracks in gas cylinders after internal and external cleaning, including a base frame and a bottle washing assembly; the bottle washing assembly is installed on the upper left side of the base frame. This invention enables automatic transfer of gas cylinders and simultaneous cleaning of both the outer and inner walls, shortening processing time. It automatically inserts a mounting rod into the gas cylinder, emitting light through LED beads while simultaneously rotating the cylinder. Observation is conducted through a second miniature camera and multiple first miniature cameras, avoiding missed defects and ensuring product quality.

Description

Technical Field

[0001] This invention relates to the field of gas cylinder processing, and in particular to an automatic detection device for cracks in the inner wall of gas cylinders during internal and external cleaning. Background Technology

[0002] In existing technology, during the processing of gas cylinders, after the cylinder is formed, threads need to be machined inside the nozzle. The resulting metal shavings remain on the surface and inside of the cylinder. The cylinders need to be collected and manually placed in cleaning equipment to clean the surface and inner wall separately. After the inner wall is dried, the cylinders are collected again. Then, a flexible tube lamp is inserted into the cylinder, and the cylinder is manually rotated to visually inspect the inner wall for cracks. This cleaning process requires multiple manual collections and placements of the cylinders, and separate cleaning of the outer and inner surfaces, resulting in a lengthy processing time. Furthermore, when manually inspecting the inner wall, it is difficult to aim the flexible tube lamp at the narrow nozzle, and even after insertion, the remaining gap is small, making it prone to omissions during visual inspection. This allows potentially defective cylinders to flow into subsequent processes, affecting product quality.

[0003] In summary, there is an urgent need for an automatic detection device for internal and external cleaning and crack detection of gas cylinders to overcome the above problems. Summary of the Invention

[0035] The protective cover 127 has multiple openings for ventilation.

[0036] The inner diameter of the brush tube 119 gradually increases from top to bottom, which reduces the amount of dirty water generated during the cleaning at the top flowing to the bottom of the gas cylinder.

[0037] The bottom surface of the first pusher column 110 is designed to be concave to facilitate contact with the bottom of the cylinder, thus preventing the cylinder from shaking excessively during cleaning.

[0039] The left-side transfer unit includes a second fixed frame 210, a third fixed rod 211, a third spur gear 212, a third fixed frame 213, a limiting cylinder 214, and a second gear ring 215. The left side of the fixed disk 209 is fixedly connected to the second fixed frame 210. The third fixed rod 211 is rotatably connected to the second fixed frame 210. The third fixed rod 211 is rotatably connected to the fixed disk 209. The right side of the third fixed rod 211 is fixedly connected to the third spur gear 212. The left side of the third fixed rod 211 is fixedly connected to the third fixed frame 213. The left side of the third fixed frame 213 is rotatably connected to the limiting cylinder 214. The lower part of the limiting cylinder 214 is fixedly connected to the second gear ring 215.

[0040] The inner wall of the limiting cylinder 214 is equipped with multiple spring beads for locking the gas cylinder.

[0041] The crack detection assembly includes a second electric push rod 301, a fifth fixing plate 302, a mounting rod 303, a fourth small motor 304, a fourth spur gear 305, an LED bead 306, a first miniature camera 307, and a second miniature camera 308. Two second electric push rods 301 are fixedly connected to the upper rear part of the third support frame 201. The telescopic ends of the two second electric push rods 301 are fixedly connected to the fifth fixing plate 302. The mounting rod 303 is fixedly connected to the upper front part of the fifth fixing plate 302. The fourth small motor 304 is installed on the lower rear part of the fifth fixing plate 302. The output shaft of the fourth small motor 304 is fixedly connected to the fourth spur gear 305. An LED bead 306 is installed at the top of the mounting rod 303. Multiple first miniature cameras 307 are equidistantly installed on the front side of the mounting rod 303. A second miniature camera 308 is installed on the upper front side of the mounting rod 303 via a connecting block. The second miniature camera 308 is located above the multiple first miniature cameras 307.

[0042] During operation, the first conveyor belt 102 is controlled to transport the gas cylinders to be processed forward. Two first limiting plates 103 limit the gas cylinders, thus transporting them into the cylinder 114 until they are blocked by four baffles 124. Then, the first small motor 112 is started, and its output shaft rotates 90 degrees clockwise (viewed from left to right). This causes the cylinder 114 to rotate the gas cylinder 90 degrees, so that the cylinder opening faces downwards. Simultaneously, the cylinder 114 drives the first fixing rod 113 to rotate within the fourth fixing plate 111. Then, the first electric slider 108 is controlled to slide downwards on the second electric slide rail 107, causing the third fixing plate 109 to move the first pusher column 110 downwards. The first pusher 110 is moved so that its bottom surface contacts the bottom of the gas cylinder, pushing the gas cylinder downwards and causing it to press against the baffle 124. This causes the baffle 124 to rotate about the torsion spring shaft connected to the U-shaped frame 123. Simultaneously, the second electric slider 125 slides upwards on the first electric slide rail 105, causing the second support frame 126 to move the protective cover 127 upwards. This allows the spray pipe 128 to be inserted into the gas cylinder, bringing the protective cover 127 into contact with the gas cylinder. Then, the second electric slider 125 and the first electric slider 108 slide downwards synchronously, causing the first pusher 110 and the protective cover 127 to clamp the gas cylinder. As the gas cylinder continues to move downwards, it enters the brush cylinder 119, and simultaneously... The nozzle 118 is connected to an external clean water delivery device, which sprays water onto the outer surface of the gas cylinder. Simultaneously, it controls the start of the second small motor 115. The output shaft of the second small motor 115 drives the first spur gear 116 to rotate the first gear ring 120. The first gear ring 120 then drives the brush cylinder 119 to rotate within the first fixed frame 117, thus brushing the outer surface of the gas cylinder. The resulting water flow onto the water collection cover 121 and is collected by an external receiving device through the first liquid guide pipe 122. Simultaneously, the water spray pipe 128 sprays water into the gas cylinder through multiple spray holes via the external clean water delivery device, cleaning the inner wall of the gas cylinder. The wastewater generated during cleaning flows into the protective cover 127 and is collected by an external receiving device through the second liquid guide pipe 129. After the gas cylinder is cleaned, it continues to move downwards and is inserted into the limiting cylinder 214, which then squeezes the spring beads on the inner wall of the limiting cylinder 214, compressing the spring beads and thus locking the gas cylinder. Then, the second electric slider 125 and the first electric slider 108 slide back in opposite directions, controlling the main motor 207 to start. With the view from top to bottom as a reference, the output shaft of the main motor 207 rotates 90 degrees counterclockwise, which in turn causes the fixed plate 209 to drive the four transfer units to rotate 90 degrees, causing the limiting cylinder 214 to drive the gas cylinder to make a circular motion. Then, the inner wall of the gas cylinder is dried using the existing equipment. After the drying process is completed, the output shaft of the main motor 207 rotates 180 degrees counterclockwise, which in turn causes the limiting cylinder 214 to move the gas cylinder to directly above the mounting rod 303.

[0043] Then, the two second electric push rods 301 are controlled to extend simultaneously to push the fifth fixing plate 302 upward, thereby inserting the mounting rod 303 into the gas cylinder. At the same time, the fourth spur gear 305 and the second gear ring 215 mesh with each other. Then, the lamp bead 306 is controlled to turn on, emitting light towards the inner wall of the gas cylinder. At the same time, the fourth small motor 304 is controlled to start. The output shaft of the fourth small motor 304 drives the fourth spur gear 305 to drive the second gear ring 215 to rotate. Then, the second gear ring 215 drives the limiting cylinder 214 to rotate in the third fixing frame 213. Then, the inner wall of the gas cylinder is observed through the second miniature camera 308 and multiple first miniature cameras 307 to detect cracks in the inner wall of the gas cylinder. After the detection is completed, the two second electric push rods 301 are controlled to retract and reset.

[0044] Next, the first electric push rod 203 is extended to push the second mounting bracket 204 upward, which in turn causes the third small motor 205 to drive the second spur gear 206 upward, so that the second spur gear 206 and the third spur gear 212 mesh with each other. Then, the third small motor 205 is started. With the front to back as the reference, the output shaft of the third small motor 205 rotates 90 degrees counterclockwise, which in turn causes the third spur gear 212 to drive the third fixed rod 211 to rotate 90 degrees clockwise in the second fixed bracket 210, which in turn causes the limiting cylinder 214 to drive the gas cylinder to rotate 90 degrees clockwise, so that the bottom of the gas cylinder faces the right. Then, the fourth electric slider 218 is controlled to slide to the left on the fourth electric slide rail 217, which in turn causes the sixth fixed plate 219 to drive the second bottle pusher 220 to move to the left, and the second bottle pusher 220 pushes the gas cylinder out of the limiting cylinder 214. Then, it is manually removed for collection. The four transfer units work on the same principle.

[0046] Based on Example 1, such as Figure 14 As shown, it also includes a conveying assembly; the conveying assembly is installed on the rear left side of the base frame 1; the conveying assembly includes a fourth support frame 401, a third electric slide rail 402, a third electric slider 403, a fourth fixed frame 404, a second conveyor belt 405, and a second limiting plate 406; the fourth support frame 401 is fixedly connected to the rear left side of the base frame 1; a third electric slide rail 402 is fixedly connected to the front and rear upper sides of the fourth support frame 401; two third electric sliders 403 are slidably connected to each of the two third electric slide rails 402; a fourth fixed frame 404 is fixedly connected to the upper side of each third electric slider 403; a second conveyor belt 405 is installed between the four fourth fixed frames 404; a second limiting plate 406 is fixedly connected to the upper rear side of the two front fourth fixed frames 404; another second limiting plate 406 is fixedly connected to the upper front side of the two rear fourth fixed frames 404.

[0047] As the sixth fixed plate 219 drives the second pusher column 220 to move to the left, the second pusher column 220 pushes the gas cylinder out of the limiting cylinder 214. At the same time, the third electric sliders 403 on the two third electric slide rails 402 are controlled to move to the right, thereby causing the four fourth fixed frames 404 to drive the second conveyor belt 405 to move to the right, and at the same time drive the two second limiting plates 406 to move to the right, so that the right side of the second conveyor belt 405 is close to the mouth of the gas cylinder, and the gas cylinder is pushed out of the limiting cylinder 214 onto the second conveyor belt 405. Then, the second conveyor belt 405 is controlled to start, conveying the gas cylinder to the left. At the same time, the third electric sliders 403 on the two third electric slide rails 402 slide in the opposite direction to reset, so that the second conveyor belt 405 conveys the gas cylinder after the test to the subsequent processing station for processing.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
