When actually used, a vibration device is installed inside the valve stem installation component 4. The vibration device is not shown in the figure, and an existing industrial vibration device can be used, which will not be described in detail here. The valve stem installation component 4 includes a storage The hopper 41 is fixedly mounted in the middle of the component support frame 3. Before use, the worker needs to fill the valve stem into the hopper 41. A limiting plate 42 is fixedly mounted at the bottom of the hopper 41. A plurality of limiting holes 44 are provided on the limiting plate 42. The size of the limiting holes 44 is changed according to the actual production line speed and the type of fire extinguisher produced. The larger the limiting hole 44, the faster the material falling speed. A guide shell 43 is fixedly mounted on the lower surface of the limiting plate 42. A position limiting opening 45 is provided on one side of the guide shell 43. The conveying component 1 is installed A plurality of clamping seats 8 are installed, and two symmetrical clamping members 9 are installed on the upper surface of the clamping seats 8. The opposite sides of the two clamping members 9 clamp the fire extinguisher valve head 10. The bottom end of the guide housing 43 is provided with two symmetrical mounting plates 5. The opposite sides of the two mounting plates 5 are provided with symmetrical conveyor belts 51. The side of the conveyor belt 51 close to the position limiting opening 45 is provided with a valve stem moving component 6. A first motor 52 is provided on one side of the mounting plate 5. The driving end of the first motor 52 passes through the mounting plate 5 and is installed on one of the conveyor belts 51. The two conveyor belts 5 1, a valve stem body 7 is provided in the middle of the two conveyor belts 51, the valve stem body 7 includes a valve stem short handle 71, a valve stem sealing disk 72, and a valve stem long handle 73, the width of the first gap is greater than the diameter of the valve stem short handle 71 and the valve stem long handle 73, the width of the first gap is smaller than the diameter of the valve stem sealing disk 72, the height of the position limiting opening 45 is smaller than the length of the valve stem long handle 73, the height of the position limiting opening 45 is greater than the length of the valve stem short handle 71, and the height of the position limiting opening 45 is greater than the height and diameter of the valve stem sealing disk 72.

[0022] In actual use, the front end of the conveying component 1 extends to the previous processing production line of the fire extinguisher head. After the previous production line assembles the fire extinguisher head, the clamping member 9 is used to fix the fire extinguisher head. Then the conveying component 1 transfers the fixed fire extinguisher head to the first position. At the same time, the valve stem body 7 inside the storage hopper 41 will fall into the inside of the guide shell 43 along the flow limiting hole 44, and finally fall on the surface of the conveyor belt 51. Because there is a first gap in the middle of the conveyor belt 51, the valve stem body 7 will have the following Figure 3 There are two states shown, the first state is that the long stem handle 73 is located above the short stem handle 71, and the second state is that the short stem handle 71 is located above the long stem handle 73. If it is in the first state, under the continuous transmission of the conveyor belt 51, the long stem handle 73 will be blocked by the position limiting opening 45, and under the continuous transmission of the conveyor belt 51, the valve stem body 7 in the first state is changed to the second state, and then transmitted to the valve stem moving component 6 through the position limiting opening 45, and then the valve stem moving component 6 conveys the valve stem body 7 in the second state to the inside of the fire extinguisher valve head 10, and then the conveying component 1 continuously drives the fire extinguisher valve head 10 equipped with the valve stem body 7 to the bottom of the spring mounting component 2, and then the spring mounting component 2 places the spring inside the fire extinguisher valve head 10, and then the conveying component 1 continuously drives the fire extinguisher valve head 10 equipped with the valve stem body 7 to the bottom of the spring mounting component 2, and then the spring is placed inside the fire extinguisher valve head 10 by the spring mounting component 2, and then the conveying component 1 continuously drives the fire extinguisher valve head 10 equipped with the spring The valve head 10 of the fire extinguisher is transported to the bottom of the plug installation component 11, and the plug installation component 11 screws the plug into the interior of the fire extinguisher valve head 10. The spring installation component 2 and the plug installation component 11 are devices existing in the prior art and will not be described in detail here. Therefore, by setting the conveyor belt 51 and the position limiting port 45, workers do not need to manually install the valve stem body 7. They only need to pour the valve stem body 7 into the interior of the storage hopper 41. The storage hopper 41 and the vibration device will transport the valve stem body 7 to the surface of the conveyor belt 51, and then the conveyor belt 51 and the position limiting port 45 will use the same method to change the valve stem body 7 to the second state. Workers do not need to touch the working machine, but only need to feed the working machine, thereby avoiding safety accidents caused by workers' negligence during installation, reducing the number of workers required for the entire line, increasing the degree of automation, and improving production.

[0023] Furthermore, conventionally, when changing the upper and lower positions of workpieces, sensors and computer terminals are mostly used for judgment and then a robot is used to adjust the position. This method is relatively costly and difficult for some small manufacturing companies to afford. Therefore, a position limiting opening 45 is opened. The state of the workpiece can be unified only by opening a slot, and all the workpieces can be adjusted to the installation state. This can be achieved with a practical and simple mechanical structure, which greatly reduces the company's cost on the machine and makes the device more practical.

[0024] The valve stem moving component 6 includes two symmetrical first lower guide rods 61, a first upper guide rod 62 is provided above the first lower guide rod 61, the first lower guide rod 61 is fixedly mounted on the upper surface of the spring mounting component 2, a second lower guide rod 63 is fixedly mounted on the end of the first lower guide rod 61 away from the position limiting opening 45, a third lower guide rod 64 is fixedly mounted on the end of the second lower guide rod 63 away from the first lower guide rod 61, a second upper guide rod 621 is fixedly mounted at a position corresponding to the first upper guide rod 62 and the second lower guide rod 63, a third upper guide rod 622 is fixedly mounted at a position corresponding to the second upper guide rod 621 and the third lower guide rod 64, a material distribution support plate 65 is fixedly mounted on the end of the third upper guide rod 622 away from the second upper guide rod 621, and the material distribution support plate 6 5 is fixedly installed on one side, and a rotating plate 67 is rotatably installed on the opposite side of the two second motors 66. The driving end of the rotating plate 67 passes through the material distribution support plate 65 and is fixedly installed in the middle of the rotating plate 67. A plurality of evenly distributed diverter plates 671 are installed on the rotating plate 67. A semicircular shell 68 is fixedly installed at one end of the two third lower guide rods 64 away from the second lower guide rod 63. The semicircular shells 68 are symmetrically distributed and the two semicircular shells 68 form a cylindrical frame. The inner ring diameter of the cylindrical frame is equal to the diameter of the valve stem sealing disk 72. The semicircular shell 68 is located above the fire extinguisher valve head 10. There is a second gap between the two first lower guide rods 61, and the width of the second gap is equal to the width of the first gap. The width of the diverter plate 671 is equal to the width of the second gap.

[0025] When the valve stem body 7 in the second state is transported to the outside of the valve stem mounting component 4 by the conveyor belt 51, it will enter the top of the first lower guide rod 61. Under the continuous transmission of the conveyor belt 51, the workpiece will fall above the second lower guide rod 63, and finally fall above the third lower guide rod 64 through the second lower guide rod 63. At this time, the second motor 66 will not rotate. Only when the fire extinguisher valve head 10 is in the installation position, the second motor 66 will rotate a unit angle, where one unit angle is determined according to the specifications of the installed valve stem body 7 and the specifications of the diverter plate 671. When the second motor 66 rotates an angle, a valve stem body 7 will be pushed into the interior of the semicircular shell 68, and at the same time, another diverter plate 671 will fall to block the next valve stem body 7, preventing one fire extinguisher valve head 10 from falling into multiple valve stem bodies 7, further improving the degree of automation of the device and reducing the possibility of failure in the installation of the valve stem.
