The driving motor 40 is assembled on the frame 10, and the frame 10 provides supporting function for the driving motor 40, optionally, in fig. 2, the driving motor 40 and the turntable 20 are separated by the wallboard 11, so that the driving motor 40 and the turntable 20 are arranged on opposite sides by taking the wallboard 11 as a boundary, thereby ensuring that the arrangement of the driving motor 40 and the turntable 20 on the frame 10 is more reasonable and compact, avoiding the avoidance of the arrangement position of the driving motor 40 due to the arrangement of the driving motor 40 on the same side of the frame 10 as the turntable 20, and increasing the size of the frame 10 due to the avoidance of the turntable 20; in addition, the driving motor 40 is also used for driving the turntable 20 to rotate so as to meet the power requirement of the turntable 20 rotating relative to the frame 10.

Meanwhile, the automatic inflation mechanism 30 includes an inflation head 31, a motion driver 32 for driving the inflation head 31 to move, and an origin alignment device 34. The turntable 20 is provided with the air container 22 with the air charging nozzle 221 to meet the requirement that the air container 22 rotates along with the turntable 20, alternatively, in fig. 3, as an example, the air container 22 also protrudes outside the outer periphery 21 of the turntable 20 to provide a avoiding position for installing other components on the turntable 20, and in addition, the air container 22 is designed to be annular, but not limited thereto. The motion driver 32 is mounted to the housing 10, and the housing 10 provides support for the motion driver 32.

Furthermore, the origin alignment device 34 includes an origin positioning driver 341 mounted on the frame 10, an origin positioning member 342 mounted on an output end 3411 of the origin positioning driver 341, and an origin positioning member 343 mounted on the turntable 20. The origin matching piece 343 protrudes outwards from the outer periphery 21 of the turntable 20 so as to facilitate the abutting and positioning of the origin matching piece 343 and the origin positioning piece 342; origin setter 343 also follows the rotation of carousel 20 relative to frame 10. The origin positioning member 342 is driven by the origin positioning driver 341 to at least change between an initial position shown in fig. 8a and a positioning position shown in fig. 8b, and the origin positioning member 342 moves to a rotation path 3433 (see fig. 8 b) of the origin matching member 343 when in the positioning position shown in fig. 8b, at this time, the origin positioning member 342 can be positioned in abutment with the origin matching member 343 rotating along with the turntable 20, and the positioned state is shown in fig. 8 c.

The sensor 50 is located beside the origin positioning driver 341, and the sensor 50 is disposed opposite to the rotation path 3433 of the origin matching unit 343, so as to meet the sensing requirement of the sensor 50 on the origin matching unit 343 rotating along with the turntable 20. The air charging head 31 is assembled at the output end of the motion driver 32, after the origin positioning piece 342 is abutted to the origin matching piece 343 for positioning, at this time, the air charging head 31 is configured to make its motion path pass through the air charging nozzle 331, so that the air charging head 31 can move to a position correctly jointed with the air charging nozzle 331 after the origin positioning piece 342 is abutted to the origin matching piece 343 for positioning, so as to meet the requirement of the air source where the air charging head 31 is located for charging the air storage container 22. When the air container 22 is filled to the required capacity, the movement driver 32 drives the air charging head 31 to move away from the air charging nozzle 331 to reset, and the origin positioning driver 341 drives the origin positioning member 342 to move away from the origin matching member 343 to switch to the initial position, so as to provide an avoidance effect for the rotation of the turntable 20. More specifically, the following is:

As shown in fig. 1, 3 and 4 to 9, the origin matching member 343 is provided with a matching groove 3431 located outside the turntable 20, the origin positioning member 342 is provided with a positioning contour 3421 matched with the matching groove 3431, and the origin positioning member 342 is positioned with the origin matching member 343 by the matching of the positioning contour 3421 and the matching groove 3431; this design makes the abutting positioning between the origin positioning piece 342 and the origin matching piece 343 more reliable.

More specifically, in fig. 1, 3, and 4-9, as an example, the mating groove 3431 is a circular arc groove, and the positioning profile 3421 is a circular profile to effectively reduce frictional resistance of the positioning profile 3421 into the mating groove 3431. For example, the origin locator 342 is a rolling bearing, it is apparent that in other embodiments, the origin locator 342 may be a wheel or a circular axle structure; in addition, the origin matching member 343 is a plate structure, but not limited thereto.

As shown in fig. 1, 8a, 8b and 8c, the origin positioning driver 341 is located above the turntable 20 correspondingly, so that the origin positioning driver 341 is disposed above the frame 10, and thus the size of the left and right sides of the frame 10 is not increased. Further, the origin positioning driver 341 is a cylinder or a hydraulic cylinder with the output end 3411 arranged downward, so that the origin positioning member 342 is quickly switched between the initial position and the positioning position.

Compared with the prior art, the origin positioning device comprises an origin positioning driver 341 assembled on the frame 10, an origin positioning piece 342 assembled on an output end 3411 of the origin positioning driver 341, and an origin matching piece 343 assembled on the turntable 20 and protruding outside the outer periphery 21 of the turntable 20; therefore, in the process of positioning the origin, the origin positioning driver 341 drives the origin positioning member 342 to switch from the initial position shown in fig. 8a to the positioning position shown in fig. 8B, so that the origin positioning member 342 in the positioning position moves onto the rotation path 3433 of the origin positioning member 343 and is positioned in abutment with the origin positioning member 343 which follows the rotation of the turntable 20 in the direction indicated by the arrow B, and the state is shown in fig. 8c, thereby realizing the origin positioning of the turntable 20 and the frame 10; then, the air charging head 31 is driven by the movement driver 32 to move towards the air charging nozzle 221 of the air storage container 22, so that the air charging head 31 is correctly engaged with the air charging nozzle 33; after the engagement, the air container 22 is automatically inflated by the air source in which the air inflation head 31 is located. Therefore, the seam welder 100 of the present utility model can realize the automatic inflating operation of the air container 22 on the turntable 20 by the inflating head 31, and can also improve the seam welding efficiency.

It should be noted that, the above-described sensor 50 is configured to provide an auxiliary effect for the origin positioning driver 341 to drive the origin positioning member 342 to switch to the positioning position, that is, when the origin positioning member 343 follows the turntable 20 to the position sensed by the sensor 50 along the direction indicated by the arrow B, the origin positioning driver 341 drives the origin positioning member 342 to move downward to the positioning position as shown in fig. 8B according to the signal of the origin positioning member 343 sensed by the sensor 50, for example, the sensor 50 transmits the signal of sensing the origin positioning member 343 to the control portion of the origin driver 341, and the control portion controls the moving portion of the origin driver 341 to drive the origin positioning member 342 to move according to the signal, so that the origin positioning member 342 is abutted to the origin positioning member 343 which follows the turntable 20 to rotate along the direction indicated by the arrow B, so as to achieve the purpose of positioning the turntable 20 and the frame 10. In addition, in order to make the positional relationship between the sensor 50 and the origin positioning driver 341 more compact, the sensor 50 and the origin positioning driver 341 are fixed to the frame 10 (in particular, the wall plate 11) by a mounting bracket 12 in a state shown in fig. 1. Obviously, in other embodiments, the inductor 50 may be eliminated.
