Description

Technical Field

[0001] This utility model relates to the technical field of appearance inspection equipment, specifically a stable gas cylinder appearance inspection device. Background Technology

[0002] Gas cylinders mainly refer to bottle-shaped metal or non-metal sealed containers for storing and transporting permanent gases, liquefied gases, dissolved gases, or adsorbed gases. Due to their special usage conditions, gas cylinders need to undergo various tests, such as appearance inspection, sealing performance testing, pressure bearing capacity testing, etc. Among them, appearance inspection mainly checks whether there is mechanical damage, corrosion and abnormal deformation on the cylinder body, and assesses the integrity of the threaded connection parts.

[0003] Existing methods for visual inspection of gas cylinders mainly include two types: one is to inspect the gas cylinders using mechanical devices, which has low inspection efficiency; the other is to inspect the gas cylinders using visual inspection equipment, but existing visual inspection equipment is not well adapted to gas cylinders.

[0004] For example, the aforementioned problem exists in patent (CN221037261U); it describes "a gas cylinder appearance inspection instrument. A base, a support platform is fixedly installed at the upper center of the base, and a gas cylinder is vertically placed on the support platform; a first connecting plate is fixedly installed on both sides of the base, and the gas cylinder is visually inspected by a mechanical device to avoid the uncertainty of manual inspection and make the inspection results more accurate; through the structure of the push plate, under the elastic force of the spring, the roller is made to fit tightly against the outer wall of the gas cylinder, and by controlling the up and down movement of the push plate, the roller can inspect any corner of the outer wall of the gas cylinder, and when there is an unevenness on the outer wall of the gas cylinder, the roller will move horizontally; by using a pencil to mark on a cardboard, after the roller and push plate move horizontally when they encounter an uneven area of ​​the gas cylinder, the pencil mark on the cardboard changes from a dot to a line, making it easy to visually see whether the outer wall of the gas cylinder is flat." However, the mechanical device used for gas cylinder appearance inspection has low inspection efficiency, far lower than that of visual appearance inspection equipment. While existing visual inspection equipment is efficient, it is not well-suited for gas cylinders. Patent (CN219496144U) describes "a gas cylinder appearance inspection instrument, including a horizontally rotatable rotating tray with two rubber-coated electric rollers on it, the axes of which are parallel; and a laser 3D scanner mounted on the upper side of the rotating tray. This utility model is mainly used for appearance inspection in the gas cylinder inspection process, saving on-site space, reducing manual operation, saving inspection time, reducing information recording errors, and accelerating the informatization transformation of the inspection and testing industry. It is an example of effectively integrating industrial design equipment with inspection equipment and applying it to the inspection and testing industry, and also an informatization improvement for gas cylinder inspection." However, the use of a laser 3D scanner for gas cylinder appearance inspection only provides one inspection station. Each gas cylinder must be removed from the inspection rack before another can be placed on it for inspection, resulting in low inspection efficiency.

[0005] To address the aforementioned issues of low efficiency in visual inspection of gas cylinders using mechanical devices, which is far lower than that of visual inspection equipment, and the poor adaptability of existing visual inspection equipment to gas cylinders (requiring the removal of one cylinder from the inspection rack before placing another), we propose a stable visual inspection device for gas cylinders. Summary of the Invention

[0006] The purpose of this invention is to provide a stable gas cylinder appearance inspection device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stable gas cylinder appearance inspection device, including a conveyor frame and an appearance inspection frame. The appearance inspection frame is disposed above the conveyor frame. Several rotatably connected support shafts are horizontally arranged on the top of the conveyor frame. Frustum-shaped sleeves are symmetrically arranged on both sides of the outer wall of the support shafts. The outer diameter of one adjacent end of two frustum-shaped sleeves is smaller than the outer diameter of the other end. A transmission mechanism for the support shafts is provided at the bottom of the conveyor frame. A movably connected bracket is provided on the inner side of the conveyor frame below the appearance inspection frame. A rotating support mechanism for the gas cylinder is provided on the top of the bracket.

[0008] Furthermore, the bracket includes a fixed plate and a support plate. The fixed plate is fixedly connected to the inner wall of the conveyor frame. Several cylinders are vertically arranged between the fixed plate and the support plate. The rotating support mechanism is located on the top of the support plate.

[0009] Furthermore, the rotating support mechanism includes a support frame, with two first rubber rollers symmetrically connected at both ends of the top of the support frame. A motor is provided on one side of the first rubber rollers on the outer wall of the support frame, and the output end of the motor is fixedly connected to one end of the first rubber roller.

[0010] Furthermore, the rotating support mechanism also includes two auxiliary frames, each with two rotatably connected second rubber rollers symmetrically arranged at both ends of its top, the second rubber rollers being parallel to the first rubber roller.

[0011] Furthermore, the lengths of the support frame and the auxiliary frame are equal, the length of the support frame is less than the length of the support shaft, and the length of the support frame is greater than the distance between the two frustum-shaped sleeves on the outer wall of the support shaft.

[0012] Furthermore, the second rubber roller is the same size as the first rubber roller, and the sum of the widths of the first rubber roller and the motor is less than the distance between the frustum-shaped sleeves on the outer walls of two adjacent support shafts. The width of the first rubber roller is greater than one-third of the distance between the frustum-shaped sleeves on the outer walls of two adjacent support shafts.

[0013] Furthermore, the appearance inspection frame includes a three-dimensional adjustment frame, and the output end of the three-dimensional adjustment frame is provided with a visual inspection mechanism.

[0014] Furthermore, the visual inspection mechanism is a visual acquisition camera or a laser 3D scanner.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model, by setting up a conveyor frame, an appearance inspection frame, a support shaft, frustum-shaped sleeves, a transmission mechanism, a bracket, and a rotating support mechanism, provides rolling support for the gas cylinder on both sides of the top of the support shaft. The dimensions and positions of the two frustum-shaped sleeves are defined, forming an isosceles trapezoidal conveying channel. This effectively and stably conveys cylindrical gas cylinders, offering better adaptability and improving the stability and safety of gas cylinder transport. The conveyor frame transports the gas cylinders to the appearance inspection frame, enabling continuous transport for appearance inspection. This is convenient, quick, and efficient. The rotating support mechanism drives the gas cylinders to rotate as they are transported to the appearance inspection frame, facilitating rapid inspection of different areas on the cylinder surface and making the inspection process more convenient.

[0017] 2. In this utility model, by setting a fixed plate, a support plate, a cylinder, a support frame, a first rubber roller, and a motor, the extension and retraction movement of the cylinder can drive the support plate to move up and down, thereby realizing the lifting and lowering movement of the rotating support mechanism, which facilitates the lifting, support, and detachment of the gas storage bottle; during the upward movement of the rotating support mechanism, the tops of the two first rubber rollers contact and support the bottom sides of the gas storage bottle, and the motor can drive the first rubber rollers to rotate. The two motors are synchronously controlled, so that the two motors work synchronously and drive the two first rubber rollers to rotate synchronously, and the rotation direction of the two first rubber rollers is the same, so that the gas storage bottle rotates, which facilitates the appearance inspection frame to perform appearance inspection work on different positions on the surface of the gas storage bottle.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please see Figures 1-5 This utility model provides a technical solution: a stable gas cylinder appearance inspection device, including a conveyor frame 1 and an appearance inspection frame 2. The appearance inspection frame 2 is located above the conveyor frame 1. The top of the conveyor frame 1 is horizontally provided with several rotatably connected support shafts 101. The outer walls of the support shafts 101 are symmetrically provided with frustum-shaped sleeves 102. The outer diameter of one adjacent end of the outer wall of two frustum-shaped sleeves 102 is smaller than the outer diameter of the other end. The bottom of the conveyor frame 1 is provided with a transmission mechanism 103 for the support shafts 101. The inner side of the conveyor frame 1 is provided with a movably connected bracket 3 below the appearance inspection frame 2. The top of the bracket 3 is provided with a rotating support mechanism 301 for the gas cylinder. The appearance inspection frame 2 includes a three-dimensional adjustment frame 201. The output end of the three-dimensional adjustment frame 201 is provided with a visual inspection mechanism 202.

[0027] In one embodiment, the visual inspection mechanism 202 is a visual acquisition camera or a laser 3D scanner. When using a visual acquisition camera, the camera takes a picture of the gas cylinder to acquire a visual image, and then transmits the acquired image data to a visual image analysis system for comparative analysis to determine whether the appearance image of the gas cylinder is qualified. When using a laser 3D scanner, the scanner performs 3D data scanning on the gas cylinder, and then transmits the 3D scan data of the gas cylinder to a 3D data analysis system for analysis to determine whether the 3D appearance data of the gas cylinder is qualified.

[0028] The working principle of this utility model:

[0029] Refer to the instruction manual appendix Figures 1-5This utility model comprises a conveyor frame 1, an appearance inspection frame 2, a support shaft 101, a frustum-shaped sleeve 102, a transmission mechanism 103, a bracket 3, and a rotating support mechanism 301. The conveyor frame 1 transports the gas cylinder to be inspected to the area below the appearance inspection frame 2, which performs appearance inspection on the gas cylinder. The support shaft 101 provides rotational support for the frustum-shaped sleeve 102 at the top of the conveyor frame 1. The two frustum-shaped sleeves 102 provide rolling support for the gas cylinder on both sides of the top of the support shaft 101. The dimensions and positions of the two frustum-shaped sleeves 102 are defined, forming an isosceles trapezoidal structure. The conveying channel can effectively and stably transport cylindrical gas cylinders, with better adaptability to gas cylinder transport, and can effectively improve the transport stability and safety of gas cylinders; the transmission mechanism 103 drives the support shaft 101 to rotate, so that all support shafts 101 rotate in the same direction, thereby ensuring that the support shaft 101 drives the gas cylinders to be transported in the same direction through the frustum-shaped sleeve 102, ensuring that the gas cylinders are transported to the bottom of the appearance inspection frame 2, realizing the continuous transport of gas cylinders, so that the gas cylinders can be continuously transported to the bottom of the appearance inspection frame 2 for appearance inspection, which is convenient and quick to operate and has higher work efficiency;

[0030] The bracket 3 supports the rotating support mechanism 301, which in turn drives the gas cylinder to rotate. This allows the gas cylinder to rotate when it is transported to the bottom of the appearance inspection frame 2, facilitating rapid inspection of different positions on the surface of the gas cylinder by the appearance inspection frame 2. This makes the inspection of the gas cylinder by the appearance inspection frame 2 more convenient. The three-dimensional adjustment frame 201 in the appearance inspection frame 2 can drive the vision inspection mechanism 202 to perform rapid adjustment in three-dimensional space, facilitating the inspection of the gas cylinder by the vision inspection mechanism 202 at different positions. The vision inspection mechanism 202 performs visual inspection of the appearance of the gas cylinder.

[0031] The transmission mechanism 103 is used to drive all the support shafts 101 to rotate in the same direction. The transmission mechanism 103 can be adopted as follows: Figure 3 The structural design shown, Figure 3 The structural design includes a double-row sprocket at one end of the support shaft 101. The servo motor drives two adjacent double-row sprockets through a sprocket and a first chain. The double-row sprockets are then connected to their adjacent double-row sprockets through a second chain. This configuration ensures that all support shafts 101 rotate in the same direction. Example

[0032] Please see Figure 2 and Figure 4This utility model provides a technical solution: a stable gas cylinder appearance inspection device, wherein the bracket 3 includes a fixed plate 302 and a support plate 303, the fixed plate 302 is fixedly connected to the inner wall of the conveyor frame 1, and a plurality of cylinders 304 are vertically arranged between the fixed plate 302 and the support plate 303, and the rotating support mechanism 301 is located on the top of the support plate 303; the rotating support mechanism 301 includes a support frame 305, and two first rubber rollers 306 are symmetrically arranged at both ends of the top of the support frame 305 and rotatably connected, and a motor 307 is arranged on one side of the first rubber rollers 306 on the outer wall of the support frame 305, and the output end of the motor 307 is fixedly connected to one end of the first rubber rollers 306; the rotating support mechanism 301 also includes two auxiliary frames 308, and two second rubber rollers 309 are symmetrically arranged at both ends of the top of the auxiliary frames 308 and rotatably connected, the second rubber rollers 309 being parallel to the first rubber rollers 306.

[0033] In one embodiment, the support frame 305 and the auxiliary frame 308 are of equal length, ensuring that the support frame 305 and the auxiliary frame 308 provide more stable support for the gas cylinder. The length of the support frame 305 is less than the length of the support shaft 101, and the length of the support frame 305 is greater than the distance between the two frustum-shaped sleeves 102 on the outer wall of the support shaft 101. This limits the length of the support frame 305, ensuring that the first rubber rollers 306 at both ends of the support frame 305 can pass normally between the support shaft 101, effectively preventing the support shaft 101 from affecting the normal lifting and lowering movement of the first rubber rollers 306.

[0034] In one embodiment, the second rubber roller 309 is the same size as the first rubber roller 306, so that the contact surfaces of the first rubber roller 306 and the second rubber roller 309 with the gas cylinder are the same, which can effectively ensure the rolling support stability of the first rubber roller 306 and the second rubber roller 309 on the gas cylinder; and the sum of the widths of the first rubber roller 306 and the motor is less than the distance between the frustum-shaped sleeves 102 on the outer walls of the two adjacent support shafts 101, and the width of the first rubber roller 306 is greater than one-third of the distance between the frustum-shaped sleeves 102 on the outer walls of the two adjacent support shafts 101; limiting the widths of the first rubber roller 306 and the motor 307 can effectively ensure that the first rubber roller 306 and the motor 307 can pass normally between the two adjacent support shafts 101, and ensure the normal lifting and lowering movement of the first rubber roller 306 and the motor 307.

[0035] The working principle of this utility model:

[0036] Refer to the instruction manual appendix Figure 2 and Figure 4This utility model comprises a fixed plate 302, a support plate 303, a cylinder 304, a support frame 305, a first rubber roller 306, and a motor 307. The fixed plate 302 provides fixed support at the bottom of the support frame 3, the support plate 303 supports the rotating support mechanism 301, and the cylinder 304 provides telescopic support between the fixed plate 302 and the support plate 303. The telescopic movement of the cylinder 304 drives the support plate 303 to move up and down. Multiple cylinders in this application are synchronously controlled to ensure synchronized telescopic movement, preventing the support plate 303 from tilting, thereby achieving the lifting and lowering movement of the rotating support mechanism 301, facilitating the lifting and detachment of the gas cylinder; when the gas cylinder is not moved... When the gas cylinder is directly below the visual inspection frame 2, the cylinder 304 is in a retracted state, and both the support plate 303 and the rotating support mechanism 301 are located below the support shaft 101. At this time, the rotating support mechanism 301 is not in contact with the gas cylinder. When the gas cylinder moves directly below the visual inspection frame 2, the adjusting cylinder 304 extends, and the cylinder 304 pushes the support plate 303 upward. The rotating support mechanism 301 moves upward with the support plate 303 and passes through the gap between two adjacent support shafts 101. Then, the top of the rotating support mechanism 301 contacts and supports the bottom of the gas cylinder. The operation of the rotating support mechanism 301 can drive the gas cylinder to rotate, which facilitates the visual inspection frame 2 to perform visual inspection work on different positions on the surface of the gas cylinder.

[0037] In the rotating support mechanism 301, the support frame 305 supports the first rubber roller 306. During the upward movement of the rotating support mechanism 301, the tops of the two first rubber rollers 306 contact and support the bottom sides of the gas storage bottle. The motor 307 can drive the first rubber rollers 306 to rotate. The two motors 307 are synchronously controlled so that the two motors 307 work synchronously to drive the two first rubber rollers 306 to rotate synchronously. The rotation directions of the two first rubber rollers 306 are the same, so that the gas storage bottle rotates.

[0038] The auxiliary frame 308 provides auxiliary support for the gas storage cylinder on both sides of the support frame 305, and the second rubber roller 309 provides rotational support for the gas storage cylinder at both ends of the top of the auxiliary frame 308, which can effectively improve the safety and stability of the gas storage cylinder during rotation.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
