[0028] The technical solution protected by the present utility model is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, an automatic dispensing device for valve seats and welding rings includes: multiple feeding mechanisms, which in this embodiment include a valve seat feeding mechanism 1 and two welding ring feeding mechanisms 2, which are convenient for rapid loading. A movable module 3 is provided on one side of the multiple feeding mechanisms, and a dispensing mechanism 4 is provided on the other side of the movable module 3.

[0030] like Figure 2 、 Figure 3As shown, the valve seat feeding mechanism 1 comprises a first vibrating disc 11 for feeding, a first straight feeding channel 12 connected to the first vibrating disc 11, and a receiving assembly 13 arranged at the side of the first straight feeding channel 12 away from the first vibrating disc 11. In order to facilitate the valve seat 5 to enter the receiving assembly 13 one by one, a blocking cylinder 14 is arranged above the outlet end of the first straight feeding channel 12, the piston rod of the blocking cylinder 14 is arranged downward, and the end of the piston rod is fixed with a blocking rod 15. After the discharge of the previous valve seat 5, the piston rod of the blocking cylinder 14 is lowered, and the blocking rod 15 blocks the subsequent valve seat. When the subsequent valve seat needs to continue to be discharged, the piston rod of the blocking cylinder 14 is lifted, and the blocking rod 15 is lifted.

[0031] Further, the receiving assembly 13 comprises a first clamping cylinder 131 arranged at the outlet end of the first straight feeding channel, the first clamping cylinder 131 is connected to a turnover motor 133 through a rotating shaft 132, the main shaft of the turnover motor 133 is connected with a speed reducer, so as to reduce the rotating speed of the main shaft of the turnover motor 133, so that the first clamping cylinder 131 can rotate slowly, the turnover motor 133 is fixedly arranged on the receiving slide rail 137 below, so that the turnover motor 133 can move position. The side of the first clamping cylinder 131 away from the first straight feeding channel 12 is provided with a receiving mechanism, the receiving mechanism comprises a receiving block 136 with a hole position opened on one side, the diameter of the hole position is slightly larger than the outer diameter of the valve seat 5, a receiving cylinder 134 driving the receiving block 136 to move, and a receiving connecting rod 135 connecting the piston rod of the receiving cylinder 134 and the receiving block 136.

[0032] Specifically, the valve seat receiving process in the utility model is as follows, the valve seat is discharged through the first vibrating disc 11 and the first straight feeding channel 12, the receiving cylinder 14 drives the receiving connecting rod 135 and the receiving block 136 to move close to the outlet end of the first straight feeding channel 12, one end of the valve seat 5 enters the hole position of the receiving block 136, and the other end is still at the end of the first straight feeding channel 12. At this time, the turnover motor 133 drives the first clamping cylinder 131 to move to the valve seat on the receiving slide rail 137, the first clamping cylinder 131 clamps the valve seat 5, the receiving cylinder 134 drives the receiving block 136 to move outward, providing space for the turnover of the first clamping cylinder 131, the first clamping cylinder 131 drives the valve seat 5 to overturn, so that the valve seat 5 changes from the horizontal direction to the vertical direction, facilitating the valve seat clamping cylinder 33 at the subsequent moving module 3 to take the material.

[0033] Further, a sensor is arranged at the outlet end of the first straight feeding channel 12, which is used for sensing whether the valve seat is in place or not, so as to give a signal to the controller of the blocking cylinder 14 to block the next valve seat.

[0034] As Figure 4 , Figure 5As shown, the welding ring feeding mechanism 2 includes: a second vibrating disk 21, a second straight material channel 22 connected to the second vibrating disk 21, a material dividing assembly 23 provided at the outlet end of the second straight material channel 22, the material dividing assembly 23 including a material dividing plate 231 with at least one latching position, a material dividing cylinder 232 for driving the movement of the material dividing plate 231, and a material dividing connecting block 233 connecting the piston rod of the material dividing cylinder 232 and the material dividing plate 231. When the welding ring 6 is discharged through the second straight material channel 22, it first enters the latching position of the material dividing plate 231. The material dividing cylinder 232 drives the material dividing connecting block 233 and the material dividing plate 231 to move horizontally, and the material dividing plate 231 is used to block the discharge of the next welding ring. Then, the mobile module 3 comes over to remove the welding ring 6.

[0035] Furthermore, a proximity switch 234 with a limited position is provided on the side of the material distribution connection block 233 away from the material distribution cylinder 232. When the material distribution cylinder 232 drives the material distribution connection block 233 to move to the proximity switch 234, the proximity switch 234 will block the material distribution connection block 233 to prevent the material distribution connection block 233 from colliding with other mechanisms.

[0036] like Figure 6 、 Figure 7 As shown, the movable module 3 includes a horizontally movable servo movable mechanism 31. In this embodiment, a servo motor drives the screw to rotate, and a slider on the screw to slide. A rotary cylinder 32 is provided on the upper end surface of the servo movable mechanism 31. A mounting plate is provided on the upper end surface of the rotary cylinder 32. Two sets of liftable valve seat clamping cylinders 33 and welding ring clamping cylinders 34 are provided on the mounting plate. The valve seat clamping cylinders 33 and welding ring clamping cylinders 34 are driven up and down by a lifting cylinder 35. Driven by the movable module 3, the valve seat clamping cylinders 33 and welding ring clamping cylinders 34 respectively go to the valve seat loading mechanism 1 and welding ring loading mechanism 2 to pick up materials.

[0037] Furthermore, two sets of valve seat clamping cylinders 33 and welding ring clamping cylinders 34 are provided on the mounting plate. These two sets of cylinders are symmetrically arranged on either side of the mounting plate, and each set includes at least one valve seat clamping cylinder and at least one welding ring clamping cylinder. The rotating cylinder 32 can rotate the mounting plate 180 degrees, allowing the valve seat clamping cylinders 33 and welding ring clamping cylinders 34 on either side of the mounting plate to operate alternately, improving their efficiency.

[0038] like Figure 7 As shown, the dispensing mechanism 4 includes a dispensing head 41 and at least one fixture 42 disposed below the dispensing head. The valve seat clamping cylinder 33 at the movable module 3 first places the valve seat 5 into the fixture 42. The movable module 3 then moves out of the way, and the dispensing head 31 descends to dispense glue. Finally, the weld ring 6 is installed into the valve seat 5, completing the entire valve seat weld ring loading, dispensing, and assembly process.

[0039] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
