[0015] Compared with the prior art, this utility model provides an automatic alignment device for gas cylinder filling, which has the following advantages:

[0016] 1. This automatic alignment device for gas cylinder filling, through its alignment mechanism, first places the gas cylinder at the center of the top of the support platform when filling is required, inside the first and second clamping plates. Three cylinders can be placed at a time. Under the action of the bidirectional threaded rod and the sliding rod, the two moving platforms move relative to each other along the bidirectional threaded rod, thereby moving the first and second clamping plates. The second clamping plate slides within the support plate through the connecting shaft and adapts to the shape of the gas cylinder with the elastic force of the spring. This design can quickly and accurately position the gas cylinder at the center of the processing table, ensuring the stability of the gas cylinder. With the help of the photoelectric transmitter and photoelectric receiver, the subsequent accurate alignment of the gas cylinder filling port can be achieved, greatly shortening the preparation time before filling and significantly improving the filling efficiency. The first clamping plate is V-shaped and the second clamping plate is arc-shaped, and both are equipped with rubber pads on the inner side, increasing the contact area between the clamping plate and the gas cylinder and ensuring stability.

[0017] 2. This automatic alignment device for gas cylinder filling, through its filling mechanism, allows the gas cylinder to be filled to be fixed in place by the support platform, the first clamping plate, and the second clamping plate. The first cylinder then moves the moving seat, the support frame gas storage tank, and the filling head back and forth, positioning the filling head at the top of the gas cylinder. A photoelectric receiver and a photoelectric transmitter work together to monitor the cylinder's position in real time. If the position of the filling head deviates from the position of the gas cylinder opening during the movement of the first cylinder, the action of the first cylinder can be adjusted promptly to achieve automatic alignment. The inclusion of a temporary storage device and a gas pump allows for precise control of the filling volume and speed, ensuring that the filling quality meets standard requirements. The three symmetrically distributed filling heads ensure even filling of the gas cylinder, shortening the filling time and further improving filling efficiency. Attached Figure Description

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figures 1-7This utility model provides a technical solution: an automatic alignment device for filling gas cylinders, including a processing table 1, a base 4 fixedly connected to the bottom of the processing table 1, an alignment mechanism 2 provided on the top of the processing table 1, and a filling mechanism 3 provided on the top of the processing table 1.

The front of the spring 292 is fixedly connected to the rear of the support plate 28. The rear of the spring 292 is fixedly connected to the front of the limit block 293.

[0033] The rear side of the bidirectional threaded rod 24 is rotatably connected to the inner side of the support platform 21, and the slide rod 25 is fixedly connected to the inner side of the support platform 21, so that the moving platform 26 can be moved under the action of the bidirectional threaded rod 24 and the slide rod 25. The moving platform 26, the first clamping plate 27, the support plate 28, the second clamping plate 29, the connecting shaft 291, the spring 292 and the limiting block 293 are provided in two sets. The two sets of moving platforms 26, the first clamping plate 27, the support plate 28, the second clamping plate 29, the connecting shaft 291, the spring 292 and the limiting block 293 are symmetrically distributed around the bidirectional threaded rod 24, and the two sets of first clamping plates 27 are in a sliding state with each other, so that the gas cylinder can be better fixed by setting two sets.

[0034] The first clamping plate 27 and the second clamping plate 29 are V-shaped and arc-shaped, respectively, and rubber pads are provided on the inner sides of the first clamping plate 27 and the second clamping plate 29, so as to improve the fixing effect of the gas cylinder under the joint action of the first clamping plate 27 and the second clamping plate 29.

[0035] Example 2

[0036] Please see Figures 1-7Furthermore, based on Embodiment 1, the filling mechanism 3 further includes a fixing block 32, which is fixedly connected to the bottom of the processing table 1. A first cylinder 33 is fixedly connected to the rear side of the fixing block 32. A movable seat 31 is fixedly connected to the front side of the first cylinder 33. The movable seat 31 is slidably connected to the inside of the processing table 1. A load-bearing frame 34 is fixedly connected to the top of the movable seat 31. An air storage box 35 is fixedly connected to the top of the load-bearing frame 34. A three-way pipe 37 is fixedly connected to the front side of the air storage box 35. An air pump 36 is fixedly connected to the periphery of the three-way pipe 37. A hose 39 is fixedly connected to the bottom of the three-way pipe 37. A temporary storage device 391 is fixedly connected to the bottom of the hose 39. An inflation head 392 is fixedly connected to the bottom of the temporary storage device 391. A photoelectric receiver 393 is fixedly connected to the bottom of the temporary storage device 391. A second cylinder 38 is fixedly connected to the top of the temporary storage device 391.

[0037] The gas pump 36 and the second cylinder 38 are fixedly connected to the top of the support frame 34, and the hose 39 is slidably connected inside the support frame 34, so that gas can be delivered to the temporary storage device 391 and the inflation head 392 under the action of the gas pump 36. There are three inflation heads 392, which are symmetrically distributed at the bottom of the temporary storage device 391, so that three gas cylinders can be filled at the same time.

[0038] In actual operation, when this device is used to fill gas cylinders, the gas cylinders are first placed at the center of the top of the support platform 21, inside the first clamping plate 27 and the second clamping plate 29. Three cylinders can be placed at a time. The servo motor 22 drives the moving platform 26, which is threadedly connected to the bidirectional threaded rod 24, to move. The moving platform 26 slides around the slide rod 25. Under the action of the bidirectional threaded rod 24 and the slide rod 25, the two moving platforms 26 move relative to each other along the bidirectional threaded rod 24, thereby moving the first clamping plate 27 and the second clamping plate 29. When the second clamping plate 29 contacts the gas cylinder, it slides within the support plate 28 via the connecting shaft 291 and adapts to the shape of the gas cylinder using the elastic force of the spring 292. This continues until the first clamping plate 27 is positioned around the gas cylinder according to its size, thus fixing the gas cylinder. The first clamping plate 27 is V-shaped. The first and second clamps 29 are arc-shaped and have rubber pads on their inner sides, which increases the contact area between the clamps and the gas cylinder and ensures stability.

[0039] When the gas cylinder is fixed, the first cylinder 33 can drive the moving seat 31, the load-bearing frame 34, the gas storage box 35, and the filling head 392 to move back and forth, so that the filling head 392 is at the top of the gas cylinder opening. The photoelectric receiver 393 works with the photoelectric transmitter 23 to monitor the position of the gas cylinder in real time. When the position of the filling head 392 deviates from the position of the gas cylinder opening during the movement of the first cylinder 33, the action of the first cylinder 33 can be adjusted in time to achieve automatic alignment. When the adjustment is completed, the second cylinder 38 drives the temporary storage device 391 and the filling head 392 to move, so that the filling head 392 is at the periphery of the gas cylinder opening and in contact with the gas cylinder opening. The gas in the gas storage box 35 is delivered to the hose 39 through the three-way pipe 37 by the gas pump 36, and then delivered to the filling head 392 through the temporary storage device 391 for filling.

[0040] The temporary storage device 391 and the gas pump 36 can precisely control the inflation volume and inflation speed, ensuring that the filling quality meets the standard requirements. The three symmetrically distributed inflation heads 392 can evenly inflate the gas cylinder, shorten the filling time, and further improve the filling efficiency.

[0041] In the process of using this invention, the servo motor 22, the first cylinder 33, the second cylinder 38, the photoelectric transmitter 23 and the photoelectric receiver 393 can be connected to the same PLC control system to ensure synchronous and coordinated operation during the filling process.

[0042] The photoelectric transmitter used in this case is model 23: LA31, and the photoelectric receiver is model 393: LK31.
