[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The embodiment of the present application provides a gas cylinder automatic conveying equipment 10. The gas cylinder automatic conveying equipment 10 is used for conveying and state conversion of the steel cylinder filled with special gas, for example. Typically, the special gas refers to the gas with special requirements on purity, variety and property applied in a specific field. The special gas mainly includes electronic gas, high-purity gas and standard gas and the like. Among them, the electronic gas refers to the gas used in the electronic industry, such as high-purity nitrogen, oxygen, argon and the like, which is mainly used for manufacturing electronic components such as semiconductor, integrated circuit and the like. The high-purity gas refers to the gas with extremely high purity, such as high-purity hydrogen, helium and the like, which is widely used in scientific research, medical treatment, energy and the like. The standard gas refers to the gas prepared according to certain standards and specifications, such as standard mixed gas, standard calibration gas and the like, which is widely used in environmental monitoring, quality control and the like. Specifically, as shown in FIG. 1, FIG. 2 and Figure 3 The gas cylinder automatic conveying equipment 10 includes a steel cylinder conveying mechanism 100, a steel cylinder loading mechanism 200 and a steel cylinder unloading mechanism 300, for example. Among them, the steel cylinder conveying mechanism 100 has opposite first end E1 and second end E2; the steel cylinder loading mechanism 200 is connected to the first end E1 of the steel cylinder conveying mechanism 100; and the steel cylinder unloading mechanism 300 is arranged at the second end E2 of the steel cylinder conveying mechanism 100.

[0030] Specifically, the steel cylinder conveying mechanism 100 is used for conveying the steel cylinder from the first end E1 to the second end E2, that is, the steel cylinder conveying direction is the direction from the first end E1 to the second end E2.

[0031] In addition, as shown in Figure 2a , Figure 2b and Figure 2c , the steel bottle loading mechanism 200 comprises, for example, a state conversion assembly 210 and a steel bottle clamping assembly 220. The state conversion assembly 210 is hinged at the first end E1 of the steel bottle conveying mechanism 100. The steel bottle clamping assembly 220 is connected to the state conversion assembly 210. The state conversion assembly 210 can rotate relative to the steel bottle conveying mechanism 100. The steel bottle clamping assembly 220 is used to clamp and fix the steel bottle to be conveyed in a vertical state. The state conversion assembly 210 is used to rotate the steel bottle to be conveyed in a vertical state around the steel bottle conveying mechanism 100 to convert the steel bottle to be conveyed into a horizontal state, and to send the steel bottle to the steel bottle conveying mechanism 100 for conveying to the empty steel bottle placement area in a horizontal state.

[0032] In this way, the embodiments of the present application can realize the loading, conveying and unloading of the gas steel bottle by setting the steel bottle loading mechanism, the steel bottle conveying mechanism and the steel bottle unloading mechanism, thereby solving the technical problems of large labor amount, low conveying efficiency and safety hazards in the prior art caused by manual handling of the steel bottle. The labor amount of handling the steel bottle is greatly reduced, the efficiency of conveying the steel bottle is improved, and the safety of the state conversion and conveying of the steel bottle is also improved. Further, under normal circumstances, the full bottle state steel bottle is placed vertically during use, and in order to save the space occupied by the steel bottle, the empty bottle state steel bottle can be placed horizontally in multiple layers. Therefore, after the full bottle state steel bottle is used, the steel bottle in a vertical state needs to be placed horizontally and stacked in multiple layers. The embodiments of the present application can clamp, convert and convey the steel bottle to be conveyed in a vertical state (empty steel bottle after use) to the empty steel bottle placement area and place, convey and unload in a horizontal state, thereby solving the problem of increased workload and insecurity caused by manual state conversion in the prior art.

[0033] Further, as shown in Figure 2a , Figure 2b and Figure 2cAs shown, the state conversion assembly 210 comprises, for example, a first support 211, a second support 212, a first transmission assembly 213 and a second transmission assembly 214. The first support 211 is hinged on one side of the first end E1 of the cylinder conveying mechanism 100. The second support 212 is arranged opposite to the first support 211 and is hinged on the other side of the first end E1 of the cylinder conveying mechanism 100. The first transmission assembly 213 is hinged between the one side of the first end E1 of the cylinder conveying mechanism 100 and the first support 211. The second transmission assembly 214 is arranged opposite to the first transmission assembly 213 and is hinged between the other side of the first end E1 of the cylinder conveying mechanism 100 and the second support 212.

[0034] As shown, Figure 2c The first support 211 and the second support 212 are, for example, parts of a steel frame structure, such as a triangular steel frame, which is formed by welding steel pipes or angle steels. The first support 211 and the second support 212 are arranged opposite to and apart from each other. One end of the first transmission assembly 213 is hinged on one side of the first end E1 of the cylinder conveying mechanism 100, and the other end is hinged on the first support 211. One end of the second transmission assembly 214 is hinged on the other side of the first end E1 of the cylinder conveying mechanism 100, and the other end is hinged on the second support 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 pneumatic cylinders). Under the drive of a hydraulic pump or a pneumatic pump, the first transmission assembly 213 and the second transmission assembly 214 can drive the cylinder clamping assembly 220 and the cylinder to be conveyed to convert between the vertical state and the horizontal state.

[0035] In addition, as shown in Figure 2a and Figure 2b The cylinder clamping assembly 220 comprises, for example, a first clamping piece 221, a second clamping piece 222, a third clamping piece 223, a third transmission assembly 224 and a fourth transmission assembly 225. The first clamping piece 221 is hinged on one side of the first support 211 adjacent to the second support 212. The second clamping piece 222 is arranged opposite to the first clamping piece 221 and is hinged on one side of the second support 212 adjacent to the first support 211. One end of the third clamping piece 223 is hinged on the first support 211, and the third clamping piece 223 is rotatable relative to the first support 211 and cooperates with the first clamping piece 221 and the second clamping piece 222 to form a receiving space SP for fixing the cylinder to be conveyed. The third transmission assembly 224 is hinged between the first support 211 and the first clamping piece 221. The fourth transmission assembly 225 is hinged between the second support 212 and the second clamping piece 222.

[0036] Specifically, one end of the first clamping member 221 and the second clamping member 222 can rotate relative to the state transition assembly 210, and the third clamping member 223 can rotate relative to the first support 211. The third clamping member 223 can cooperate with the first clamping member 221 and the second clamping member 222 to form a receiving space SP for fixing the steel cylinder to be conveyed. For example, there may be multiple third clamping members 223. Figure 2c The following explanation uses two third clamping components 223 as an example. When the cylinder clamping assembly 220 is in... Figure 2a In the state shown, the user can open the third clamping member 223, push the vertically positioned cylinder to be transferred into the receiving space SP, and then close the third clamping member 223 onto the second bracket 212. In this way, the third clamping member 223, together with the first clamping member 221 and the second clamping member 222, clamps and fixes the cylinder to be transferred. Then, the first transmission assembly 213 and the second transmission assembly 214 drive the cylinder clamping assembly 220 and the cylinder to be transferred from a vertical state to a horizontal state, positioned above the cylinder transfer mechanism 100. The third transmission assembly 224 and the fourth transmission assembly 225 are, for example, hydraulic transmission assemblies (e.g., hydraulic cylinders) or pneumatic transmission assemblies (e.g., air cylinders). Driven by a liquid pump or a gas pump, the third transmission assembly 224 and the fourth transmission assembly 225 are activated, which in turn drive the first clamping member 221 and the second clamping member 222 to open, allowing the horizontally positioned steel cylinder to fall from the accommodating space SP onto the steel cylinder conveying mechanism 100, so that the steel cylinder conveying mechanism 100 can convey it to the steel cylinder unloading mechanism 300 and place it in a horizontal position.

[0037] As stated above, Figure 1c As shown, the cylinder conveying mechanism 100 includes, for example, a conveying support 110, multiple rollers 120, and a first driving device (not shown). The multiple rollers 120 are arranged sequentially on the conveying support 110 and spaced apart from each other. The first driving device is mounted on the conveying support 110 and connected to the multiple rollers 120. The first driving device is, for example, a drive motor such as a stepper motor or a servo motor. The first driving device drives the multiple rollers 120 to rotate, thereby transferring the cylinders located on the multiple rollers 120 through the friction between the multiple rollers 120 and the cylinders to be conveyed.

[0038] Furthermore, such as Figure 3As shown, the roller shaft 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 bottle to be conveyed. Optionally, in the direction along the axis of the roller shaft 120, the cross-sectional size of the roller 123 gradually increases from the middle of the roller 123 to the two ends of the roller 123. That is, the cross-sectional size of the two ends of the roller 123 is larger than the cross-sectional size of the middle of the roller 123. In this way, the cross-sectional size of such a roller 123 can make the steel bottle to be conveyed in a predetermined direction, avoiding the deviation of the direction of the steel bottle when conveying.

[0039] In addition, as shown in Figure 4a and Figure 4b The steel bottle unloading mechanism 300, for example, includes a steel bottle placing rack 310 and a steel bottle unloading assembly 320. The steel bottle placing rack 310 is located on one side of the second end E2 of the steel bottle conveying mechanism 100. The steel bottle unloading assembly 320 is hinged on one side of the steel bottle placing rack 310 adjacent to the conveying support 110. The steel bottle unloading assembly 320 can rotate relative to the conveying support 110 and enter or exit the gap between the plurality of roller shafts 120 of the second end E2.

[0040] Specifically, the steel bottle placing rack 310, for example, is a rack for storing empty steel bottles conveyed by the steel bottle conveying mechanism 100, and the empty steel bottles are in a horizontal placement state on the steel bottle placing rack 310. The steel bottle unloading assembly 320 is used to unload the empty steel bottles conveyed by the steel bottle conveying mechanism 100 onto the steel bottle placing rack 310. When there are no empty bottles on the plurality of roller shafts 120 of the second end E2, the steel bottle unloading assembly 320 is in the gap between the plurality of roller shafts 120; when there are empty bottles on the plurality of roller shafts 120 of the second end E2, the steel bottle unloading assembly 320 rotates and exits the gap between the plurality of roller shafts 120, and unloads the empty bottles on the plurality of roller shafts 120 onto the steel bottle placing rack 310.

[0041] Further, as shown in Figure 4aAs shown, the cylinder unloading assembly 320 includes, for example, an unloading frame 321 and a second driving device 322. The unloading frame 321 is hinged to the side of the cylinder placement rack 310 adjacent to the conveying support 110. The second driving device 322 is disposed on the cylinder placement rack 310 and connected to the unloading frame 321. The unloading frame 321 can rotate relative to the conveying support 110 under the drive of the second driving device 322, and can enter or exit the gap between the plurality of rollers 120. The second driving device 322 can be, for example, a drive motor such as a stepper motor or a servo motor. Furthermore, the unloading frame 321 includes, for example, a rotating shaft 3211, a plurality of flipping rods 3212, and a connecting member 3213. The rotating shaft 3211 passes through the cylinder placement rack 310. One end of each of the plurality of flipping rods 3212 is sequentially connected to the rotating shaft 3211 and is spaced apart from each other along the axial direction of the rotating shaft 3211. Connector 3213 connects to the other end of each of the plurality of flipping rods 3212. Driven by the second drive 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 center of the arc-shaped rod is higher than 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 empty cylinders onto the cylinder placement rack 310.

[0042] Typically, the automatic gas cylinder conveying device 10 may also include a control unit (not shown in the figure). The control unit may include, for example, a controller such as an MCU, CPU, DSP, or other components with data processing and control functions. Specifically, the control unit may connect, for example, 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.

[0043] In addition, such as Figures 5a to 5e As shown, the working process of the automatic gas cylinder conveying device 10 provided in this embodiment of the present invention is as follows:

[0044] 1. For example Figure 5a As shown, the user can open the third clamping member 223 and clamp and fix the cylinder to be transferred, which is placed vertically in the cylinder usage area D1, in the receiving space SP. Then, the user can close the third clamping member 223 and connect the third clamping member 223 to the second bracket 212 (see...). Figure 5b). Next, the first transmission assembly 213 and the second transmission assembly 214 drive the bottle to be conveyed to change from the vertical state to the horizontal state and to be above the roller shaft 120 of the bottle conveying mechanism 100 (see Figure 5c ). Then, the third transmission assembly 224 and the fourth transmission assembly 225 act and drive the first clamping member 221 and the second clamping member 222 to open, so that the bottle to be conveyed in the horizontal state falls from the containing space SP to the bottle conveying mechanism 100 (see Figure 5d ).

[0045] 2. The bottle conveying mechanism 100 conveys the bottle to be conveyed from the first end El to the second end E2 to the second end E2, for example, at the empty bottle placing area D2 of the special gas bottle.

[0046] 3. When reaching the preset position (for example, reaching the bottle placing rack 310), the second list device 322 of the bottle unloading mechanism 300 drives the unloading rack 321 to rotate upward to unload the bottle to be conveyed to the bottle placing rack 310 and to be placed in the horizontal state, so as to complete the conveying of the bottle to be conveyed in the vertical state from the bottle using area D1 to the bottle in the horizontal state at the empty bottle placing area D2.

[0047] In addition, it should be noted that the various specific technical features described in the foregoing embodiments can be combined in any suitable manner without contradiction, and in order to avoid unnecessary repetition, the various possible combinations are not described again. Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
