[0037] As Figure 1 , 2 shown, the conveying component 3 includes a conveyor belt 31, a driving member 32 and a sensor 33. The conveyor belt 31 is horizontally arranged and is arranged for rotary conveying. The driving member 32 is arranged on one side of the conveyor belt 31 close to the vibrating disk 2, and the driving member 32 drives the conveyor belt 31 to convey. The sensors 33 are arranged on both sides of the path where the conveyor belt 31 conveys the valve body 21, and the sensors 33 are used to monitor the valve body 21.

[0038] It is worth mentioning here that the conveying component 3 is horizontally arranged and horizontally conveys the valve bodies 21 output from the vibrating disk 2 one by one in an orderly manner, avoiding the phenomenon of material jamming during the conveying process of the valve bodies 21. Moreover, sensors 33 are arranged on both sides of the conveying path of the valve bodies 21 to monitor whether there are any abnormalities in the conveyed valve bodies, avoiding problems such as material jamming and flipping during the conveying process of the valve bodies 21.

[0039] As Figure 2 , 5 shown, the mounting seat 4 includes a mounting plate 43, trapezoidal blocks 44, a U-shaped plate 45 and stoppers 46. The mounting plate 43 is horizontally arranged on the frame 1. The trapezoidal blocks 44 are symmetrically arranged on the upper end surface of the mounting plate 43. The U-shaped plate 45 is fixedly arranged between the two groups of trapezoidal blocks 44, and the opening of the U-shaped plate 45 is for the upward pushing unit 62 to push and lift. The stoppers 46 are symmetrically installed on the U-shaped plate 45.

[0040] It should be noted here that the opening direction of the U-shaped plate 45 faces the pushing component, which facilitates the pushing of the valve body 21 to the installation station 42.

[0041] As Figure 7 shown, the mounting plate 43 is horizontally moved and adjusted through the optical axis components 47 arranged in parallel on both sides below, and the optical axis components 47 are mounted on the frame 1.

[0042] It is worth mentioning here that by setting the adjustable optical axis components 47, the position of the installation station 42 can be quickly adjusted according to the production of products of different models.

[0043] As shown in the figure, the pushing component 5 further includes a pneumatic slider 51, a pushing plate 52 and a protective plate 53; the pneumatic slider 51 is slidably arranged on the mounting plate 43; the pushing plate 52 is fixedly installed on the pneumatic slider 51, and the pushing plate 52 moves synchronously with the pneumatic slider 51; the protective plate 53 is installed on the top of the pushing plate 52, and the end of the protective plate 53 extends out of the pushing plate 52. When the pushing plate 52 pushes the valve body 21, the protective plate 53 covers the top of the valve body 21.

[0044] It is worth mentioning here that a pushing component 5 is arranged at the output end of the conveying component 3. The pushing component 5 includes a protective plate 53 that prevents the valve body 21 from flipping during the pushing process. By cooperating the pushing component 5 with the conveying component 3 to convey the valve body 21 to the installation station 42, the time for the welding and pressing component 6 to wait for the next valve body 21 to be conveyed to the installation station 42 after completing one valve welding is reduced, and at the same time, the stability of conveying the valve body 21 is ensured.

[0045] As Figure 2 、 6 shown, an adjustment groove 531 is formed on the protective plate 53, and the adjustment groove 531 is used to adjust the length of the protective plate 53 extending out of the pushing plate 52.

[0046] It is worth mentioning here that by forming the adjustment groove 531 on the protective plate 53, the length of the protective plate 53 exceeding the end of the pushing plate 52 can be adjusted according to different models of the valve body 21, which can prevent the valve body 21 from flipping without interfering with the valve welding work.

[0047] As Figure 2 、 7As shown in FIGS. 8, the hot pressing unit 61 includes an upper base 611, a first cylinder 612, a welding head 613, a second cylinder 614 and a limiting plate 615; the upper base 611 is horizontally installed on the frame 1; the first cylinder 612 is fixedly installed on the upper base 611 and is arranged to push downward in the vertical direction; the welding head 613 is installed on the push rod of the first cylinder 612, and the welding head 613 moves up and down with the push rod. An electric heating element is provided on the welding head 613; the second cylinder 614 is fixedly installed at the bottom of the upper base 611 and is arranged to push downward in the vertical direction; the limiting plate 615 is sleeved outside the welding head 613, the top of the limiting plate 615 is connected to the push rod of the second cylinder 614, and the limiting plate 615 is driven by the second cylinder 614 to move up and down.

[0048] It should be noted here that a shoulder stop 6131 is provided on the welding head 613, and the cross-section of the shoulder stop 6131 is larger than the hole on the limiting plate 615.

[0049] It is worth mentioning here that during the process of closing and clamping the valve body 21 and the upper film 41 between the hot pressing unit 61 and the upward pushing unit 62 to complete the valve welding, the limiting plate 615 will first contact the stopper 46 to clamp the upper film 41, and then the welding head 613 will press down. When the welding head 613 presses down to the appropriate working position, the top of the limiting plate 615 will support and limit the further descent of the welding head 613 to prevent the welding head 613 from applying excessive downward pressure to damage the valve body 21;

[0050] As Figure 7 shown, the upper base 611 is connected to the frame 1 through two sets of parallel optical axis slide rail groups 616, and the upper base 611 is horizontally moved and adjusted through the optical axis slide rail groups 616.

[0051] It is worth mentioning here that by setting the adjustable optical axis slide rail groups 616, the position of the hot pressing unit 61 can be quickly adjusted according to the production of different models of products.

[0052] As Figure 2 、 7 、8 shown, the upward pushing unit 62 includes a third cylinder 621 and a welding base 622; the third cylinder 621 is fixedly installed at the bottom of the mounting plate 43; the welding base 622 is fixedly sleeved on the push rod of the third cylinder 621, and the welding base 622 is driven by the third cylinder 621 to move up and down.

[0053] As Figure 2 shown, the welding base 622 is located at the opening of the U-shaped plate 45. Initially, the upper end surface of the welding base 622 is lower than the upper end surface of the U-shaped plate 45.

[0054] It is worth mentioning here that by setting the upper end face of the welding and pressing base 622 to be lower than the surrounding plane in the horizontal height, the valve body will not jam materials in the moving path when it is pushed onto the welding and pressing base 622. The valve body 21 is pushed until it stops when it contacts the inflection point 451 of the U-shaped plate 45. The upper end face of the welding and pressing base 622 being lower than the upper end face of the U-shaped plate 45 can play a positioning role for the valve body 21.

[0055] The working process is as follows:

[0056] Start the switch. The vibrating disk 2 automatically arranges the valve bodies 21 and conveys the valve bodies 21 to the conveyor belt 31 one by one. The driving member 32 drives the pulley to rotate, so that the conveyor belt 31 transports the valve bodies 21 to the output end. The pneumatic slider 51 slides towards the installation station 42, and the push plate 52 pushes the valve bodies 21 on the conveyor belt 31 onto the welding and pressing base 622. The pneumatic slider 51 slides back. The second cylinder 614 pushes the limiting plate 615 down to contact the stopper 46 to clamp the upper film. The third cylinder 621 pushes the welding and pressing base 622 to move upward, and the first cylinder 611 pushes the welding head 612 to move downward. The welding and pressing base 622 and the welding head 612 synchronously clamp the valve body 21 and the upper film 41, and weld the valve body 21 to the upper film 41.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
