[0037] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0038] See the attached Figure 2 As shown, an assembly device 100 for a valve body connecting rod 1a of the present utility model is used for the assembly of the valve body connecting rod 1a and the plug 1b. The assembly device 100 includes a pressing head assembly 1. The pressing head assembly 1 is used to suck a plug 1b and press the sucked plug 1b into the valve body connecting rod 1a. The pressing head assembly 1 can move along the Z direction to press the plug 1b downward.

[0039] See the attached Figure 3 and the attached Figure 4 As shown, the pressing head assembly 1 includes a suction block 11, a lifting rod 12, and a spring 13. The suction block 11 includes a rod body portion 111. The rod body portion 111 is provided with a suction channel 1111 along the Z direction. The suction channel 1111 can generate negative pressure, and the plug 1b can be sucked at the lower end of the suction channel 1111. The lifting rod 12 is sleeved outside the rod body portion 111 and can move along the axial direction of the rod body portion 111. The lower end of the lifting rod 12 can abut against the end of the valve body connecting rod 1a. Initially, the lower end of the lifting rod 12 is not higher than the lower end of the suction channel 1111, and the lifting rod 12 can move upward under the push of the valve body connecting rod 1a. The spring 13 is sleeved outside the rod body portion 111 and is located above the lifting rod 12. The spring 13 is used to provide a downward pressing force for the lifting rod 12 on the valve body connecting rod 1a.

[0040] In this embodiment, the plug 1b is sucked by the suction block 11. After sucking the plug 1b, the entire pressing head assembly 1 moves downward, and the lifting rod 12 presses tightly on the valve body connecting rod 1a. Since the valve body connecting rod 1a is fixed, the lifting rod 12 will move upward under the push of the valve body connecting rod 1a, compressing the spring 13. The spring 13 stores energy during the compression process and applies a downward force to the lifting rod 12 to make the lifting rod 12 press tightly on the valve body connecting rod 1a and limit the position of the valve body connecting rod 1a. At this time, the adsorption block 3 can drive the adsorbed plug 1b to continue to move downward and press the plug 1b on the valve body connecting rod 1a. In this embodiment, the lifting rod 12 pressing the valve body connecting rod 1a can move up and down, will make way for the valve body connecting rod 1a when the plug 1b is pressed, and can press tightly on the valve body connecting rod 1a, improving the assembly accuracy. At the same time, because the lifting rod 12 is in flexible contact with the valve body connecting rod 1a, the damage to the valve body connecting rod 1a is reduced.

[0041] Initially, the lifting rod 12 is in the first position under the action of its own gravity or the spring 13. At the first position, the lower end of the lifting rod 12 is not higher than the lower end of the suction channel 1111, so as to ensure that when the entire indenter assembly 1 moves downward, the lifting rod 12 can first abut against the valve body connecting rod 1a to position the valve body connecting rod 1a. When the suction channel 1111 sucks the plug 1b, the plug 1b will protrude downward from the rod body portion 111, ensuring that the plug 1b can be inserted into the valve body connecting rod 1a.

[0042] See the appendix Figure 3 and the appendix Figure 4 As shown, the indenter assembly 1 further includes a guide block 14. The guide block 14 is sleeved outside the rod body portion 111. A guide cavity 15 is formed between the guide block 14 and the rod body portion 111. The rod body portion 111 and the lifting rod 12 pass downward through the guide cavity 15. The spring 13 is arranged in the guide cavity 15, and the lifting rod 12 moves up and down along the guide cavity 15.

[0043] In this embodiment, the added guide block 14 provides guidance for the lifting of the lifting rod 12 and at the same time provides space for the placement of the spring 13. The rod body portion 111 is provided with a through hole along the Z direction, and the rod body portion 111 passes through the through hole.

[0044] In one embodiment, as shown in the attached drawings, a first convex ring 121 is circumferentially arranged on the part of the lifting rod 12 located in the guide cavity 15. The end of the guide block 14 through which the lifting rod 12 passes is provided with a second convex ring 141 extending into the guide cavity 15, and the first convex ring 121 can abut against the second convex ring 141.

[0045] In this embodiment, the first convex ring 121 and the second convex ring 141 cooperate to limit the position of the lifting rod 12. When the lifting rod 12 is in the first position, the first convex ring 121 and the second convex ring 141 abut. At this time, the lifting rod 12 moves downward by relying on gravity until now, and the spring 13 is in a natural state or slightly compressed state at this time.

[0046] See the appendix Figure 4 As shown, the suction block 11 further includes a fixing portion 112. The fixing portion 112 is located at the upper end of the rod body portion 111. The fixing portion 112 and the guide block 14 are detachably connected, and the fixing portion 112 and the guide block 14 are fixed by bolts.

[0047] During installation, first insert the lifting rod 12 into the guide block 14, and then place the spring 13. Finally, fix the guide rod and the fixing portion 112. At this time, the rod body portion 111 passes through the through hole on the lifting rod 12.

[0048] See the appendix Figure 4As shown, the upper end of the spring 13 abuts against the fixing part 112, and the lower end abuts against the lifting rod 12. When the lifting rod 12 moves upward, the spring 13 is in a continuously compressed state. The lower end of the spring 13 abuts against the first convex ring 121 of the lifting rod 12. That is, in addition to the limiting function, the first convex ring 121 also facilitates the placement of the spring 13.

[0049] See the appendix Figure 4 As shown, a negative pressure channel 1121 communicating with the suction channel 1111 is provided on the fixing part 112, and the negative pressure channel 1121 is communicated with an external negative pressure generator. One end of the negative pressure channel 1121 is communicated with the suction channel 1111, and the other end penetrates through the fixing part 112 and is connected to an air pipe joint 16 fixed on the fixing part 112. The air pipe joint 16 is connected to the negative pressure generator through an air pipe. The negative pressure generator generates negative pressure in the suction channel 1111 through the negative pressure channel 1121 to adsorb the plug 1b.

[0050] See the appendix Figure 2 As shown, the assembling device 100 further includes a moving component 2. The pressing head component 1 is fixed on the moving component 2, and the moving component 2 can drive the pressing head component 1 to make linear reciprocating movements in the X direction and the Z direction respectively. The moving component 2 includes a transverse movement module and a lifting module. The lifting module is fixed on the transverse movement module and makes a linear reciprocating movement in the X direction driven by the transverse movement module. The plug 1b component is fixed on a lifting plate, and the lifting plate is connected to the lifting module and is lifted under the drive of the lifting module. The transverse movement module and the lifting module are both linear modules, which will not be elaborated here.

[0051] See the appendix Figure 2 As shown, an adsorption block 3 is also fixed on the moving component 2. The adsorption block 3 is fixed on the lifting plate, and the adsorption block 3 and the pressing head component 1 move synchronously. The adsorption block 3 is used to adsorb the valve body connecting rod 1a inserted with the plug 1b. After the plug 1b and the valve body connecting rod 1a are inserted, the adsorption block 3 adsorbs the assembled plug 1b and valve body connecting rod 1a as a whole and transports them to the next station.

[0052] See the appendix Figure 5 As shown, the adsorption block 3 includes a first adsorption channel 31 and a second adsorption channel 32. The first adsorption channel 31 extends along the Z direction and can generate negative pressure. The first adsorption channel 31 is located at the central position of the adsorption block 3. A plurality of second adsorption channels 32 are provided, and the plurality of adsorption channels are evenly distributed along the circumferential direction of the first adsorption channel 31. Each adsorption channel extends along the Z direction and can generate negative pressure. The first adsorption channel 31 provides an adsorption force for the plug 1b, and the second adsorption channel 32 provides an adsorption force for the valve body connecting rod 1a. That is, the adsorption block 3 can provide a uniform adsorption force for the assembled valve body connecting rod 1a and plug 1b and drive the two to move.

[0053] In this embodiment, when a punch assembly 1 moves in the first direction to pick up a plug 1b, the adsorption block 3 moves to the assembled valve body connecting rod 1a and the plug 1b, and adsorbs and moves the assembled valve body connecting rod 1a and the plug 1b, improving the processing efficiency.

[0054] See the appendix Figure 6 As shown, the valve body connecting rod 1a assembling device 100 further includes a first feeding mechanism 200 for feeding the valve body connecting rods 1a one by one. The first feeding mechanism 200 includes a first feeding position. The second feeding mechanism 300 is used for feeding the plugs 1b one by one. The second feeding mechanism 300 includes a second feeding position, and the second feeding position and the second feeding position are arranged at intervals in the X direction. During the movement of the punch assembly 1 in the X direction, it reciprocates between the first feeding position and the second feeding position. The punch assembly 1 picks up a plug 1b at the second feeding position and then moves to the first feeding position to press the plug 1b into the valve body connecting rod 1a at the first feeding position.

[0055] See the appendix Figure 7 As shown, the first feeding mechanism 200 includes a first vibrating disk 3a2a, a first transmission channel 3b2b, and a first cutting device 3c2c. The first vibrating disk 3a2a is used to transmit the valve body connecting rods 1a into the first transmission channel 3b2b and move them in the first transmission channel 3b2b. The first transmission channel 3b2b includes a first discharge port. The first cutting device 3c2c is arranged at the first discharge port. The first cutting device 3c2c includes a first cutting plate capable of moving in the Y direction, and the first cutting plate can move between the first discharge port and the first feeding position.

[0056] The second feeding mechanism 300 has the same structure as the first feeding mechanism 200, including a second vibrating disk, a second transmission channel, and a second cutting device. The second vibrating disk is used to transmit the valve body connecting rods 1a into the second transmission channel and move them in the second transmission channel. The second transmission channel includes a second discharge port. The second cutting device is arranged at the second discharge port. The second cutting device includes a second cutting plate capable of moving in the Y direction, and the second cutting plate can move between the second discharge port and the second feeding position.
