[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0045] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0046] Traditional refrigerant filling methods mostly rely on manual operations, which are not only inefficient, but also have problems such as inaccurate filling and easy leakage.

[0047] Based on the above problems, the present invention proposes a refrigerant filling device, see Figures 1 to 4 , which includes:

[0048] A docking mechanism, which has a perfusion gun head 2 for docking with the refrigerant pipe, and a guide structure for guiding the movement trajectory of the docking mechanism so that the perfusion gun head 2 is inserted into the refrigerant pipe;

[0049] The push-pull mechanism has a cylinder 15 that can move up and down, and the movement of the cylinder 15 drives the docking mechanism to move;

[0050] The connecting mechanism connects the docking mechanism and the push-pull mechanism respectively.

[0051] The cylinder 15 of the push-pull mechanism is controlled by a solenoid valve. When refrigerant is injected, the push-pull mechanism can be started by only opening the solenoid valve. After the push-pull mechanism is started, the movement of the cylinder 15 will drive the docking mechanism to move through the connecting mechanism. After the docking mechanism moves, its injection gun head 2 will be aligned with the refrigerant pipe.

[0052] The refrigerant filling machine corresponding to the filling gun head 2 can also realize automatic filling. The filling speed is preset. After the filling gun head 2 is aligned with the refrigerant pipe, the refrigerant filling machine can be turned on to realize automatic filling of the refrigerant.

[0053] Compared with the manual filling method, the present invention can realize the rapid and accurate docking of the refrigeration equipment and the filling machine through automatic filling, which significantly improves the production efficiency of the refrigeration equipment;

[0054] At the same time, the docking mechanism can achieve accurate docking of the filling gun head 2 with the refrigerant tank through the guide structure, ensuring the accuracy and stability of the refrigerant filling, thereby improving the production quality of the refrigeration equipment.

[0055] See also Figure 1 and Figure 2 , the above-mentioned docking mechanism also includes a mounting base plate;

[0056] The guide structure is at least one guide column 6 evenly distributed on the installation base plate. The guide column 6 is inserted into a through hole on the process plate provided with a refrigerant pipe to achieve positioning, and determines the movement trajectory of the docking mechanism along the direction of the through hole.

[0057] From the attached Figure 2 It can be clearly seen that the guide column 6 is arranged vertically downward, and a through hole is arranged on the process plate provided with a refrigerant filling in the refrigeration equipment. When the present invention performs docking, the guide column 6 is inserted into the through hole, so that the positioning of the entire guide structure can be achieved;

[0058] At the same time, since the guide column 6 is inserted into the through hole, when the entire docking mechanism is driven by the push-pull mechanism to move downward, it will be restricted by the through hole, causing the entire docking mechanism to only move downward in the direction of the guide column 6 and gradually be inserted into the through hole, thus realizing "determining the movement trajectory of the docking mechanism along the direction of the through hole setting".

[0059] The present invention achieves the accuracy and stability of refrigerant injection as mentioned above through the arrangement of the docking mechanism and the guide structure, thereby improving the production quality of the refrigeration equipment.

[0060] See also Figure 1 and Figure 2 In the present invention, the mounting base plate includes a first base plate 7 and a second base plate 8 which are arranged in contact with each other, and the first base plate 7 is located below the second base plate 8;

[0061] A thrust bearing 25 is disposed on the outer sides of the first bottom plate 7 and the second bottom plate 8, and the thrust bearing 25 can drive the first bottom plate 7 and the second bottom plate 8 to move relative to each other;

[0062] A heterosexual connector 26 is also provided near the thrust bearing 25 . The heterosexual connector 26 has a snap-fit ​​structure and is used to fix the first base plate 7 and the second base plate 8 .

[0063] From this attachment Figure 2It can be seen that the guide column 6 is arranged on the first base plate 7. During the automatic injection process, it is not always possible to ensure that the guide column 6 can be perfectly docked with the through hole on the process board. Therefore, it is necessary to drive the first base plate 7 and the second base plate 8 to move relative to each other through the above-mentioned thrust bearing 25. Since the guide column 6 is arranged on the first base plate 7, when the guide column 6 cannot be docked with the process board, the first base plate 7 can be driven to move through the docking bearing 25, thereby driving the position of the column 6 to change, thereby achieving the docking of the guide column 6 with the through hole on the process board, and then executing the above-mentioned injection process.

[0064] See also Figure 1 and Figure 2 The connecting mechanism includes a vertically arranged side plate 11, one side of the mounting base plate faces the side plate 11, and is vertically welded to the side plate 11, so that the mounting surface of the mounting base plate provided with the guide structure is arranged downward.

[0065] The above setting is a connection method between the connecting mechanism and the docking mechanism. Since the connecting mechanism needs to be set downward to ensure the docking of the guide column 6 and the docking of the above-mentioned perfusion gun head 2, it is necessary to ensure that the mounting surface of the mounting base must be set downward or upward;

[0066] At the same time, in order to realize the installation of the installation base plate, it is preferably arranged to ensure the vertical installation between the side panel 11 and the installation base plate. Therefore, the connection between the connecting mechanism and the docking mechanism is arranged in the above manner in the present invention, which can ensure the normal installation and movement of the docking mechanism.

[0067] See also Figure 1 and Figure 2 A connecting block 12 is provided on the side of the side plate 11 facing the push-pull mechanism, and a first horizontal plate 17 which can move up and down with the cylinder 15 is provided on the side of the cylinder 15 facing the connecting block 12. A first joint 13 is installed on the first horizontal plate 17, and the first joint 13 is fixedly connected to the connecting block 12.

[0068] The above setting is a connection method for the connecting mechanism and the push-pull mechanism, and the assembly of the two is achieved through the first joint 13 and the connecting block 12. The first cross plate 17 is used to install the above connecting block 12, and at the same time transmit the force applied by the cylinder 15 to the first joint 13. Since the first joint 13 is fixedly connected to the connecting block 12, the force applied by the cylinder 15 can be transmitted to the connecting mechanism. At the same time, the other side of the connecting mechanism is connected to the docking mechanism. Therefore, when the cylinder 15 moves and drives the first cross plate 17 to move, the docking mechanism will also move accordingly, completely docking and infusing the refrigerant.

[0069] It can be clearly seen from the above settings that in order to realize automatic control of the refrigerant filling device in the present invention, it is only necessary to control the push-pull mechanism. When the push-pull mechanism works, it will drive the docking mechanism and the connecting mechanism to make corresponding movements, thereby realizing automatic filling of the refrigerant.

[0070] As mentioned above, the movement of the cylinder 15 is controlled by the solenoid valve. Therefore, in practical applications, the automatic filling control of the refrigerant can be realized only by controlling the movement of the cylinder 15 through the solenoid valve.

[0071] See also Figure 1 and Figure 3 A fixing seat 19 is provided on the side of the side plate 11 facing away from the mounting base plate, and the fixing seat is installed on a guide shaft 21 arranged in the up-down direction;

[0072] One end of the guide shaft 21 facing the cylinder 15 is fixedly mounted on the first transverse plate 17 , and a second transverse plate 22 for fixing the guide shaft 21 is provided at one end of the guide shaft 21 away from the cylinder 15 .

[0073] The purpose of providing the guide shaft 21 here is to guide the movement trajectory of the connection mechanism. Since the cylinder 15 only provides an upward or downward force along its bearing when moving, if the movement trajectory of the connection mechanism is not guided, the connection mechanism may be offset to the outside, thereby failing to complete the docking of the docking mechanism with the refrigerant pipe.

[0074] After the guide shaft 21 is provided in the present invention, the movement trajectory of the connecting mechanism can be standardized so that the connecting mechanism can only move upward or downward along the direction of the guide shaft 21, thereby avoiding the connection mechanism deviating from the guide shaft 21 and causing the problem that the perfusion gun head 2 and the refrigerant pipe cannot be connected.

[0075] See also Figure 1 and Figure 3 A vertical plate assembly 18 is disposed on the outer side of the guide shaft 21, and two ends of the vertical plate assembly 18 are respectively connected and installed with a first horizontal plate 17 and a second horizontal plate 22;

[0076] An adjustment plate 20 is installed on the side of the riser assembly 18 facing away from the guide shaft 21 . The adjustment plate 20 can adjust the installation position of the riser assembly 18 on the back side of the guide shaft 21 .

[0077] The purpose of setting the vertical plate assembly 18 here is to fix the first horizontal plate 17 and the second horizontal plate 22. At the same time, the guide shaft 21 is also installed between the first horizontal plate 17 and the second horizontal plate 22. Therefore, the above-mentioned vertical plate assembly 18 is also used to install the guide shaft 21 through the first horizontal plate 17 and the second horizontal plate 22.

[0078] The purpose of providing the adjustment plate 20 is to adjust the position of the vertical plate assembly 18 relative to the guide shaft 21 so as to adapt to the installation of the fixing seat 19 .

[0079] See also Figure 1 and Figure 2 At least one reinforcing arm 9 is further provided on the side of the second bottom plate 8 facing the cylinder, and a first screw 10 is provided on the reinforcing arm 9;

[0080] The reinforcing arm 9 is hammer-mounted on the first bottom plate 7 and the second bottom plate 8 by means of first screws 10 .

[0081] As mentioned above, the installation base plate is composed of a first base plate 7 and a second base plate 8. Therefore, in actual work, it is necessary to ensure the installation strength between the first base plate 7 and the second base plate 8. In the present invention, the above-mentioned reinforcing arm 9 is provided to achieve stable installation between the first base plate 7 and the second base plate 8.

[0082] Based on the above structure, the refrigerant filling device proposed in the present invention mainly includes two parts, namely hardware and control;

[0083] The hardware settings are:

[0084] The refrigerant filling device is designed with automatic docking and automatic filling. The refrigerant filling device includes a push-pull mechanism and a docking mechanism. The push-pull mechanism is used to drive the docking mechanism to move. At the same time, the push-pull mechanism is used to push open the joint valve core of the refrigerant filling device to achieve docking between the filling gun head 2 and the refrigerant interface of the refrigeration equipment.

[0085] The present invention is also equipped with a high-precision refrigerant filling machine, which has functions such as refrigerant metering and filling speed control, and is connected to the filling station through a signal line to achieve automatic filling.

[0086] The refrigerant pipe joint of the process plate and the injection gun head 2 must have good sealing performance, and the docking mechanism adopts air pressure drive to ensure smooth and accurate pressing and lifting movements.

[0087] When the docking mechanism is pressed down, the solenoid valve controls the steel ball ring to lock the gun. After the gun is locked, another solenoid valve controls the top cone to push the joint valve core downward to achieve fast and accurate docking.

[0088] In other embodiments of the present invention, the above-mentioned docking mechanism may be replaced by an electromagnetic suction cup and an electric rod. In the production line of large-scale refrigeration equipment, a robotic arm may also be used to replace the docking mechanism.

[0089] The control settings are:

[0090] The main PLC is connected to the remote IO module of the filling station to control the filling station. After the refrigeration equipment enters the filling station, the push-pull mechanism on the filling station starts to work, pressing down and causing the docking mechanism to push open the joint valve core and dock with the refrigerant interface of the refrigeration equipment.

[0091] After the docking is ready, the filling station sends a filling start signal to the filling machine. After receiving the filling start signal, the filling machine starts the filling program and starts to fill the refrigerant into the refrigeration equipment. At this time, the working indicator light is on;

[0092] After the filling is completed, the filling machine sends a filling completion signal to the filling station. After receiving the filling completion signal, the filling station raises the push-pull mechanism and drives the docking mechanism to rise, and separates from the refrigerant interface of the refrigeration equipment. The filling station sends the filled refrigeration equipment out of the filling station for subsequent production processes.

[0093] When the filling is abnormal, the filling machine sends a filling abnormality signal to the filling station. After the filling station receives the filling abnormality signal, the alarm light lights up and an alarm prompt is issued. After the abnormality is manually handled, the refrigeration equipment is sent out of the station.

[0094] Based on the above arrangement, the present invention further proposes a refrigeration device having the above refrigerant filling device.

[0095] Furthermore, the refrigeration equipment is an air conditioner.

[0096] See also Figure 5 , which is a control flow chart of the refrigerant injection mechanism in the present invention, and is described here with the refrigeration equipment being an air conditioner, and includes the steps of:

[0097] "Air conditioner arrives at the station", which means the air conditioner has arrived at the filling station and is ready to start refrigerant filling;

[0098] "Docking mechanism descends". After preparing to start refrigerant injection, the injection nozzle 2 needs to be docked with the refrigerant interface of the refrigeration equipment. Therefore, the docking mechanism needs to be driven down by the push-pull mechanism to complete the docking.

[0099] "Is docking ready?" is used to determine whether the filling nozzle 2 and the refrigerant interface of the refrigeration equipment can be docked. If the docking cannot be performed, manual processing is required to check whether there is a fault;

[0100] "Send a filling signal to the filling machine", this action is executed after the above "Is it ready for docking" is judged to be yes, at which time the filling machine is started to fill the refrigerant structure of the refrigeration equipment with refrigerant;

[0101] "Filling OK / NG", where "Filling OK" is used to indicate that the refrigeration equipment has completed filling, and "Filling NG" is used to indicate that filling has stopped abnormally and a fault has occurred, and manual troubleshooting is required at this time;

[0102] "Air conditioning out of the station", this step is executed after the above-mentioned "Filling OK / NG" is judged as "OK". At this time, the air conditioner has completed the filling of refrigerant, and it is necessary to start the refrigerant filling of the next air conditioner, so the air conditioner needs to be sent out of the filling station.

[0103] It should be pointed out that the above control method in the present invention can also be used for air conditioning vacuum pumping and entropy detection testing.

[0104] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0105] 1. The present invention is provided with a docking mechanism, a push-pull mechanism, and a connecting mechanism, which can realize precise docking and filling control through the docking mechanism, ensure the accuracy and stability of refrigerant filling, and thus improve the production quality of refrigeration equipment;

[0106] 2. The present invention can realize automatic control, reduce manual operation, reduce labor costs and improve economic benefits;

[0107] 3. The present invention is easier to integrate into the existing refrigeration equipment production line, thereby improving the automation level of the production line.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
