Description

Technical Field

[0001] This utility model relates to the field of cylinder positioning technology, specifically a cylinder positioning mechanism for a refrigerant filling equipment. Background Technology

[0002] The cylinder positioning mechanism of refrigerant filling equipment is an important component to ensure accurate and efficient refrigerant filling. There are various specifications and shapes of cylinders on the market, and the positioning mechanism needs to be flexible to adapt to different types of cylinders.

[0003] The positioning accuracy of the cylinder positioning mechanism in a traditional refrigerant filling equipment is insufficient, and many positioning mechanisms are applicable to a limited number of cylinder sizes, lacking flexibility and relying on manual operation, resulting in slow filling speed and affecting overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a cylinder positioning mechanism for refrigerant filling equipment to solve the technical problems of inaccurate positioning, limited cylinder specifications, and lack of flexibility in existing filling equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cylinder positioning mechanism for a refrigerant filling device includes a base plate, a bracket fixedly mounted on the top center of the base plate, a first slide rail fixedly mounted on the top of the bracket, a first slider slidably connected to the top of the first slide rail, a second slide rail fixedly mounted on the top of the first slider, a second slider slidably connected to the top of the second slide rail, a mounting base fixedly mounted on the top of the second slider, a gear plate fixedly mounted inside the first slider, a first gear meshing with the inner side of the gear plate, one end of a rotating shaft fixedly mounted inside the first gear, a third gear fixedly mounted on the other end of the rotating shaft, a second gear meshing with the right side of the third gear, a mounting bracket fixedly mounted on the top of the base plate, a first servo motor fixedly mounted on the top of the mounting bracket, and the output end of the first servo motor fixedly connected to the second gear.

[0007] As a preferred embodiment of this utility model, the first slide rail is an annular slide rail, and the second and third slide rails are linear slide rails.

[0008] As a preferred embodiment of this utility model, a buffer is fixedly installed at the relatively distant end of the second and third slide rails.

[0009] As a preferred embodiment of this utility model, a workbench is fixedly installed on the top left side of the base plate, a first cylinder is fixedly installed on the top of the workbench via a mounting block, and a second cylinder is fixedly installed on the top right side of the mounting base.

[0010] As a preferred embodiment of this utility model, the left side of the workbench is fixedly installed on the frame, the right side of the frame is fixedly installed with a second photoelectric sensor, the left side of the bottom of the mounting base is fixedly installed with a second reflector, the left side of the top of the mounting base is fixedly installed with a first reflector, and the top of the first reflector is fixedly installed with a first photoelectric sensor.

[0011] As a preferred embodiment of this utility model, the bottom of the mounting base has a hole, and a turntable is mounted on the bottom of the mounting base. The bottom of the turntable is fixedly connected to the output end of the second servo motor.

[0012] Compared with the prior art, the cylinder positioning mechanism of the refrigerant filling equipment provided by this utility model has the following advantages: In this utility model, the handling device places the cylinder on the turntable at the bottom of the mounting base. The first servo motor drives the entire transmission device, causing the first gear to drive the gear plate to rotate, so that the first slider can move on the first slide rail. The first servo motor can control the rotation angle to ensure that the second and third slide rails at the top of the first slider are aligned after the first slider slides, reducing the possibility of equipment damage due to misalignment. The second slider moves from the second slide rail to the third slide rail. The second photoelectric sensor on the right side of the frame can emit a signal, which is reflected by the second reflector on the mounting base. The first cylinder detects the distance the second slider moves on the third slide rail. After moving to the designated position, the first cylinder fixes the position of the mounting base. The second cylinder can provide a reverse force to the cylinder during filling, improving the stability of filling. At this time, the first photoelectric sensor detects whether the cylinder mouth is aligned with the injection port through the first reflector on the top of the mounting base, which greatly improves the fault tolerance of the device. After the alignment and injection are completed, the first cylinder releases the fixation of the mounting base, and the second slider returns to the second slide rail. A buffer is fixedly installed at the relatively far end of the second and third slide rails. The buffer can absorb the impact force generated during the operation of the device, effectively improving the service life of the equipment. Attached Figure Description

[0022] See Figure 1-4As shown in the figure, a cylinder positioning mechanism for a refrigerant filling device according to an embodiment of the present invention includes a base plate 1, a bracket 2 fixedly installed at the top center of the base plate 1, a first slide rail 3 fixedly installed at the top of the bracket 2, a first slider 4 slidably connected to the top of the first slide rail 3, a second slide rail 5 fixedly installed at the top of the first slider 4, a second slider 6 slidably connected to the top of the second slide rail 5, a mounting base 7 fixedly installed at the top of the second slider 6, a gear plate 12 fixedly installed inside the first slider 4, a first gear 13 meshing with the inside of the gear plate 12, one end of a rotating shaft 14 fixedly installed inside the first gear 13, a third gear 18 fixedly installed at the other end of the rotating shaft 14, a second gear 16 meshing with the right side of the third gear 18, a mounting bracket 17 fixedly installed at the top of the base plate 1, a first servo motor 15 fixedly installed at the top of the mounting bracket 17, and the output end of the first servo motor 15 fixedly connected to the second gear 16.

[0023] See Figure 2 As shown, the first slide rail 3 is an annular slide rail, while the second slide rail 5 and the third slide rail 21 are linear slide rails. The annular shape of the first slide rail 3 can effectively reduce the size of the device and improve the space utilization rate, while the linear shape of the second slide rail 5 and the third slide rail 21 can better provide positioning applications.

[0024] See Figure 3 As shown, a buffer 22 is fixedly installed at the relatively distant end of the second slide rail 5 and the third slide rail 21. The buffer 22 can absorb the impact force and vibration generated during the operation of the equipment, thereby improving the service life of the equipment.

[0025] See Figure 4 As shown, a workbench 11 is fixedly installed on the top left side of the base plate 1. A first cylinder 9 is fixedly installed on the top of the workbench 11 via a mounting block 10. A second cylinder 27 is fixedly installed on the top right side of the mounting base 7. When the second slider 6 moves from the second slide rail 5 to a designated position on the third slide rail 21, the telescopic end of the first cylinder 9 can fix the mounting base 7 on the second slider 6. The second cylinder 27 can fix the position of the cylinder, improving the stability of the filling process.

[0026] See Figure 3 As shown, the left side of the workbench 11 is fixedly installed on the frame 8, the right side of the frame 8 is fixedly installed with a second photoelectric sensor 24, the left side of the bottom of the mounting base 7 is fixedly installed with a second reflector 23, the left side of the top of the mounting base 7 is fixedly installed with a first reflector 20, and the top of the first reflector 20 is fixedly installed with a first photoelectric sensor 19.

[0027] The first photoelectric sensor 19 and the second photoelectric sensor 24 are non-contact detection devices, and are easy to install with strong anti-interference capabilities. Both the first photoelectric sensor 19 and the second photoelectric sensor 24 are of the Omron E3Z model.

[0028] See Figure 4 As shown, the mounting base 7 has a hole at its bottom, and a turntable 26 is mounted on the bottom of the mounting base 7. The bottom of the turntable 26 is fixedly connected to the output end of the second servo motor 25. The second servo motor 25 has high flexibility, which allows the turntable 26 to rotate precisely so that the bottle mouth is aligned with the filling port faster and more accurately, thus improving the stability of the filling process.

[0029] In this embodiment of the invention, the handling equipment places the gas cylinder on the turntable 26 at the bottom of the mounting base 7. The first servo motor 15 drives the entire transmission device, causing the first gear 13 to drive the gear plate 12 to rotate, so that the first slider 4 can move on the first slide rail 3. The first servo motor 15 can control the rotation angle to ensure that after the first slider 4 slides, the second slide rail 5 and the third slide rail 21 at its top are aligned, reducing the possibility of equipment damage due to misalignment. The second slider 6 moves from the second slide rail 5 to the third slide rail 21. The second photoelectric sensor 24 on the right side of the frame 8 can emit a signal. The signal reflected by the second reflector 23 on the mounting base 7 is used to detect the distance the second slider 6 has moved on the third slide rail 21. After moving to the designated position, the first cylinder 9 will fix the position of the mounting base 7. At this time, the first photoelectric sensor 19 detects whether the mouth of the cylinder is aligned with the filling port through the first reflector 20 on the top of the mounting base 7, which greatly improves the fault tolerance of the device. After the alignment and injection are completed, the first cylinder 9 releases the fixation of the mounting base 7, and the second slider 6 returns to the second slide rail 5 to continue the next filling.

[0030] The above description illustrates the basic principles of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only for illustrating the principles of the present invention.
