[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] An embodiment of the utility model provides an automatic gas cylinder conveying device 10. The automatic gas cylinder conveying device 10 is used, for example, for the transportation, transfer and state conversion of cylinders filled with special gases. Typically, special gases refer to gases that have special requirements for purity, variety and properties used in specific fields. Special gases mainly include electronic gases, high-purity gases and standard gases, etc. Among them, electronic gases refer to gases used in the electronics industry, such as high-purity nitrogen, oxygen, argon, etc., which are mainly used in the manufacture of semiconductors, integrated circuits and other electronic components. High-purity gases refer to gases with extremely high purity, such as high-purity hydrogen, helium, etc., which are widely used in scientific research, medical treatment, energy and other fields. Standard gases refer to gases prepared according to certain standards and specifications, such as standard mixed gases, standard calibration gases, etc., which are widely used in environmental monitoring, quality control and other fields. Specifically, as shown in Figures 1, 2 and Figure 3 As shown, the automatic gas cylinder conveying device 10 includes, for example: a cylinder conveying mechanism 100, a cylinder loading mechanism 200 and a cylinder unloading mechanism 300. The cylinder conveying mechanism 100 has a first end E1 and a second end E2 opposite to each other; the cylinder loading mechanism 200 is connected to the first end E1 of the cylinder conveying mechanism 100; and the cylinder unloading mechanism 300 is arranged at the second end E2 of the cylinder conveying mechanism 100.

[0028] Specifically, the steel cylinder conveying mechanism 100 is used to convey the steel cylinder with a conveyor belt from the first end E1 to the second end E2, that is, the conveying direction of the steel cylinder is from the first end E1 to the second end E2.

[0029] In addition, if Figure 2a , Figure 2b and Figure 2cAs shown, the cylinder loading mechanism 200 includes, for example, a state conversion component 210 and a cylinder clamping component 220. The state conversion component 210 is hinged to the first end E1 of the cylinder conveying mechanism 100. The cylinder clamping component 220 is connected to the state conversion component 210. The state conversion component 210 can rotate relative to the cylinder conveying mechanism 100. The cylinder clamping component 220 is used to clamp and fix the cylinder to be conveyed in a vertical state, and the state conversion component 210 is used to rotate around the cylinder conveying mechanism 100 with the cylinder to be conveyed in a vertical state to convert the cylinder to be conveyed into a horizontal state and send it to the cylinder conveying mechanism 100, so that the cylinder conveying mechanism 100 and the cylinder unloading mechanism 300 can convey it to the empty cylinder placement area and place it in a horizontal state.

[0030] In this way, the embodiment of the utility model can realize the loading, conveying and unloading of gas cylinders by setting a cylinder loading mechanism, a cylinder conveying mechanism and a cylinder unloading mechanism, thereby solving the technical problems of large labor, low conveying efficiency and potential safety hazards in the prior art that cylinders need to be manually carried, greatly reducing the labor of cylinder handling, improving the efficiency of cylinder conveying, and improving the safety of cylinder state conversion and conveying. Further, usually, cylinders in a full bottle state are placed vertically when used, and in order to save the space occupied by the cylinders, cylinders in an empty bottle state can usually be placed horizontally and stacked in multiple layers. Therefore, after the cylinders in a full bottle state are used, it is necessary to place the cylinders in a vertical state horizontally and stack them in multiple layers. The utility model can clamp, convert and convey the cylinders to be conveyed (empty cylinders after use) in a vertical state to the empty cylinder placement area by setting a cylinder clamping assembly 220 and a state conversion assembly 210, and place, convey and unload in a horizontal state, solving the problem of increased workload and unsafety in the prior art that state conversion is performed manually.

[0031] Furthermore, if Figure 2a , Figure 2b and Figure 2c As shown, the state conversion component 210 includes, for example, a first bracket 211, a second bracket 212, a first transmission component 213, and a second transmission component 214. The first bracket 211 is hinged on one side of the first end E1 of the cylinder conveying mechanism 100. The second bracket 212 is arranged opposite to the first bracket 211 and hinged on the other side opposite to the first end E1 of the cylinder conveying mechanism 100. The first transmission component 213 is hinged between the one side of the first end E1 of the cylinder conveying mechanism 100 and the first bracket 211. The second transmission component 214 is arranged opposite to the first transmission component 213 and hinged between the other side of the first end E1 of the cylinder conveying mechanism 100 and the second bracket 212.

[0032] like Figure 2c As shown, the first bracket 211 and the second bracket 212 are, for example, parts of a steel frame structure, such as a triangular steel frame, for example, welded from steel materials such as steel pipes or angle steels. The first bracket 211 and the second bracket 212 are arranged opposite to each other and spaced apart from each other. One end of the first transmission assembly 213 is hinged to one side of the first end E1 of the steel cylinder conveying mechanism 100, and the other end is hinged to the first bracket 211. One end of the second transmission assembly 214 is hinged to the other side of the first end E1 of the steel cylinder conveying mechanism 100, and the other end is hinged to the second bracket 212. The first transmission assembly 213 and the second transmission assembly 214 are, for example, hydraulic transmission assemblies (such as hydraulic cylinders) or pneumatic transmission assemblies (such as air cylinders), respectively. Driven by a liquid pump or an air pump, the first transmission assembly 213 and the second transmission assembly 214 can drive the steel cylinder clamping assembly 220 and the steel cylinder to be conveyed to switch between a vertical state and a horizontal state.

[0033] In addition, if Figure 2a and Figure 2b As shown, the cylinder clamping assembly 220 includes, for example, a first clamping member 221, a second clamping member 222, a third clamping member 223, a third transmission assembly 224, and a fourth transmission assembly 225. The first clamping member 221 is hinged to the side of the first bracket 211 adjacent to the second bracket 212. The second clamping member 222 is arranged opposite to the first clamping member 221 and is hinged to the side of the second bracket 212 adjacent to the first bracket 211. One end of the third clamping member 223 is hinged to the first bracket 211, and the third clamping member 223 can rotate relative to the first bracket 211, and cooperates with the first clamping member 221 and the second clamping member 222 to form a accommodating space SP for fixing the cylinder to be transported. The third transmission assembly 224 is hinged between the first bracket 211 and the first clamping member 221. The fourth transmission assembly 225 is hinged between the second bracket 212 and the second clamping member 222.

[0034] Specifically, one end of the first clamping member 221 and the second clamping member 222 can rotate relative to the state conversion assembly 210, and the third clamping member 223 can rotate relative to the first bracket 211. The third clamping member 223 can cooperate with the first clamping member 221 and the second clamping member 222 to form a accommodating space SP for fixing the cylinder to be transported. For example, there are multiple third clamping members 223. Figure 2c The two third clamping members 223 are used as an example to illustrate. When the cylinder clamping assembly 220 is in Figure 2aIn the state shown in FIG. 1 , the user can open the third clamping member 223, and then push the steel cylinder to be transferred in the vertical state into the accommodating space SP, and then close the third clamping member 223 to the second bracket 212, so that the third clamping member 223 can clamp and fix the steel cylinder to be transferred with the first clamping member 221 and the second clamping member 222, and then the first transmission assembly 213 and the second transmission assembly 214 drive the steel cylinder clamping assembly 220 and the steel cylinder to be transferred from the vertical state to the horizontal state, and are located above the steel cylinder transfer mechanism 100. The third transmission assembly 224 and the fourth transmission assembly 225 are, for example, hydraulic transmission assemblies (such as hydraulic cylinders) or pneumatic transmission assemblies (such as cylinders), respectively. Driven by the liquid pump or the air pump, the third transmission assembly 224 and the fourth transmission assembly 225 are activated, and drive the first clamp 221 and the second clamp 222 to open, allowing the horizontal cylinder to be transported to fall from the accommodating space SP onto the cylinder conveying mechanism 100, so that the cylinder conveying mechanism 100 can transport it to the cylinder unloading mechanism 300 and place it in a horizontal state.

[0035] Based on the above, Figure 1c As shown, the steel cylinder conveying mechanism 100 includes, for example, a conveying bracket 110, a plurality of rollers 120, and a first driving device (not shown in the figure). The plurality of rollers 120 are sequentially arranged on the conveying bracket 110 and are spaced apart from each other. The first driving device is disposed on the conveying bracket 110 and is connected to the plurality of rollers 120. The first driving device is, for example, a driving motor such as a stepping motor, a servo motor, etc. The first driving device is used to drive the plurality of rollers 120 to rotate, so as to transmit the steel cylinders to be conveyed located on the plurality of rollers 120 through the friction between the plurality of rollers 120 and the steel cylinders to be conveyed.

[0036] Furthermore, if Figure 3 As shown, the roller 120 has a first end connecting shaft 121, a second end connecting shaft 122, and a roller 123 connected between the first end connecting shaft and the second end connecting shaft. The roller 123 is used to support and convey the steel cylinder to be conveyed. Optionally, along the axial direction of the roller 120, the cross-sectional dimensions of the roller 123 gradually increase from the middle of the roller 123 to the two ends of the roller 123. That is, the cross-sectional dimensions of the two ends of the roller 123 are greater than the cross-sectional dimensions of the middle of the roller 123. In this way, the cross-sectional dimensions of such rollers 123 can allow the steel cylinder to be conveyed to be conveyed in a preset direction, avoiding directional deviation when the steel cylinder is conveyed.

[0037] In addition, if Figure 4a and Figure 4bAs shown, the steel cylinder unloading mechanism 300 includes, for example, a steel cylinder placement rack 310 and a steel cylinder unloading assembly 320. The steel cylinder placement rack 310 is located at one side of the second end E2 of the steel cylinder conveying mechanism 100. The steel cylinder unloading assembly 320 is hinged to one side of the steel cylinder placement rack 310 adjacent to the conveying bracket 110. The steel cylinder unloading assembly 320 can rotate relative to the conveying bracket 110 and enter or exit the gap between the plurality of rollers 120 at the second end E2.

[0038] Specifically, the cylinder rack 310 is, for example, a storage rack for storing empty cylinders conveyed by the cylinder conveying mechanism 100, and these empty cylinders are placed horizontally on the cylinder rack 310. The cylinder unloading assembly 320 is used to unload the empty cylinders conveyed by the cylinder conveying mechanism 100 onto the cylinder rack 310. When there are no empty cylinders on the plurality of rollers 120 at the second end E2, the cylinder unloading assembly 320 is in the gap between the plurality of rollers 120; when there are empty cylinders on the plurality of rollers 120 at the second end E2, the cylinder unloading assembly 320 rotates and exits the gap between the plurality of rollers 120, and unloads the empty cylinders on the plurality of rollers 120 onto the cylinder rack 310.

[0039] Furthermore, if Figure 4aAs shown, the steel cylinder unloading assembly 320 includes, for example, an unloading frame 321 and a second driving device 322. The unloading frame 321 is hinged on the side of the steel cylinder placement frame 310 adjacent to the conveying support 110. The second driving device 322 is arranged on the steel cylinder placement frame 310 and connected to the unloading frame 321. The unloading frame 321 can be driven by the second driving device 322 to rotate relative to the conveying support 110 and enter or exit the gap between the multiple rollers 120. The second driving device 322 can be, for example, a driving motor such as a stepping motor, a servo motor, etc. Further, the unloading frame 321 includes, for example, a rotating shaft 3211, a plurality of flip rods 3212 and a connecting member 3213. The rotating shaft 3211 is penetrated on the steel cylinder placement frame 310. One end of each of the multiple flip rods 3212 is connected to the rotating shaft 3211 in sequence, and is arranged at intervals from each other along the axis direction of the rotating shaft 3211. The connecting piece 3213 connects the other ends of each of the plurality of flipping rods 3212. Driven by the second driving device 322, the plurality of flipping rods 3212 can rotate relative to the conveying bracket 110 and enter or exit the gap between the plurality of rollers 120 at the second end E2. Typically, the width of the flipping rod 3212 is smaller than the gap between any two adjacent rollers 120. Optionally, the flipping rod 3212 is an arc-shaped rod, and the position of the center of the arc-shaped rod is higher than the position of the axis of the rotating shaft 3211, that is, the arc-shaped rod is concave upward. In this way, the unloading rack 321 can better unload the empty cylinders onto the cylinder placement rack 310.

[0040] Typically, the automatic gas cylinder conveying device 10 may also include a control unit (not shown in the figure). The control unit, for example, includes a controller such as an MCU, a CPU, a DSP, and other components with data processing and control functions. Specifically, the control unit, for example, connects the first transmission assembly 213 and the second transmission assembly 214, the third transmission assembly 224 and the fourth transmission assembly 225, the first drive device and the second drive device 322, and is used to control the first transmission assembly 213 and the second transmission assembly 214, the third transmission assembly 224 and the fourth transmission assembly 225, the first drive device and the second drive device 322.

[0041] In addition, if Figure 5a to Figure 5e As shown, the working process of the gas cylinder automatic conveying device 10 provided by the embodiment of the utility model is as follows:

[0042] 1. If Figure 5a As shown, the user can open the third clamping member 223, clamp and fix the cylinder to be transferred placed in a vertical state in the cylinder use area D1 in the accommodating space SP, and then close the third clamping member 223 and connect the third clamping member 223 to the second bracket 212 (see Figure 5bThen, the first transmission assembly 213 and the second transmission assembly 214 drive the cylinder to be transported to be converted from a vertical state to a horizontal state, and are located above the roller 120 of the cylinder transport mechanism 100 (see Figure 5c ). Afterwards, the third transmission assembly 224 and the fourth transmission assembly 225 are activated, and drive the first clamping member 221 and the second clamping member 222 to open, so that the cylinder to be transported in a horizontal state falls from the accommodating space SP to the cylinder transport mechanism 100 (see Figure 5d ).

[0043] 2. The cylinder conveying mechanism 100 conveys the cylinder to be conveyed from the first end E1 to the second end E2. The second end E2 is located at the empty cylinder placement area D2 of the special gas cylinder, for example.

[0044] 3. When arriving at a preset position (for example, arriving at the cylinder placement rack 310), the second inventory device 322 of the cylinder unloading mechanism 300 drives the unloading rack 321 to rotate upward to unload the cylinders to be transferred onto the cylinder placement rack 310 and place them in a horizontal state, thereby completing the transfer of the cylinders to be transferred placed in a vertical state in the cylinder use area D1 to the cylinders placed in a horizontal state in the empty bottle placement area D2.

[0045] It should also be noted that the various specific technical features described in the above specific implementation methods can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention is described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
