[0061] In industrial and civil facilities, as a key device for transporting fluids, the optimization of the internal structure of a water pump directly affects the efficiency, reliability, and service life of the pump. Among them, the assembly structure of the rubber valve flap and the valve seat is particularly important. The traditional assembly of the rubber valve flap and the valve seat inside the water pump mainly achieves the seal with the valve seat through the self-gravity of the valve flap, but lacks an effective positioning mechanism, resulting in deviation during the assembly process and affecting the sealing effect.

[0062] The present utility model proposes an assembly device.

[0063] Please refer to Figure 1 、 Figure 2 and Figure 3 , in an embodiment of the present utility model, the assembly device includes:

[0064] Base 200;

[0065] Drive structure 300, provided on the base 200;

[0066] The material suction assembly 400 is used to clamp the valve seat 700. A through hole is provided in the middle of the valve seat 700. The driving structure 300 is drivingly connected to the material suction assembly 400 to drive the material suction assembly 400 to move above the valve flap; and

[0067] The positioning assembly 500 is provided on the driving structure 300. The driving structure 300 is used to drive the valve flap so that the convex column on the valve flap is inserted into the through hole.

[0068] In the technical solution of the present utility model, the base 200 serves as the installation main body. The driving structure 300 is installed on the base 200. By installing the material suction assembly 400 and the positioning assembly 500 on the driving structure 300, the driving structure 300 can drive the material suction assembly 400 and the positioning assembly 500 to move in the first direction and the second direction. The valve seat 700 is clamped at the output end of the material suction assembly 400. The driving structure 300 drives the material suction assembly 400 to move towards the valve flap, so that the valve seat 700 moves directly above the valve flap. A through hole is provided at the center of the valve seat 700. A plurality of limiting grooves are arranged at intervals and evenly along the circumferential direction of the inner circle of the through hole. A convex column is provided at the center position of one end of the valve flap facing the valve seat 700. The convex column includes fins arranged at intervals along the circumferential direction. The fins correspond to the limiting grooves. By driving the valve flap through the positioning assembly 500, each fin moves radially towards the center, and then the plurality of fins converge towards the middle, facilitating the insertion of the convex column into the through hole. After the convex column is inserted into the through hole, the positioning assembly 500 moves away from the valve flap, and the plurality of fins spread outwards and are in close fit with the through hole. In addition, the positioning assembly 500 corresponds to the center of the valve seat 700, that is, by driving the valve flap through the positioning assembly 500, the convex column can correspond to the position of the through hole, facilitating the assembly of the valve seat 700 and the valve flap, avoiding deviation during the assembly process, and the cooperation between the fin and the limiting groove can also fix the convex column to prevent the valve flap from rotating in the through hole, improving the assembly accuracy.

[0069] In a specific embodiment, the assembly device includes an upper frame 100 and a lower frame 110. The upper frame 100 is connected above the lower frame 110 and covers the base 200 and the driving structure 300 to prevent dust accumulation from affecting the operation after long-term operation. Two bases 200 are arranged in the covered space. Each base 200 is correspondingly provided with a driving structure 300, a material suction assembly 400, and a positioning assembly 500, facilitating the simultaneous assembly of multiple valve seats 700 and valve flaps.

[0070] Please refer to Figure 2 and Figure 6 , in the embodiment of the present utility model, the assembly device further includes a vertical frame 600. The driving structure 300 is drivingly connected to the vertical frame 600. The material suction assembly 400 includes:

[0071] The mounting frame 410 is provided on the vertical frame 600;

[0072] The adsorption structure 420 is disposed on the mounting frame 410 , and is used for adsorbing the valve seat 700 .

[0073] Specifically, the driving structure 300 is connected to the suction assembly 400 through the stand 600. The suction assembly 400 includes a mounting frame 410 and an adsorption structure 420. The adsorption structure 420 can adopt a pneumatic adsorption device to extract air through an electric or pneumatic vacuum pump to form a pressure difference between the adsorption structure 420 and the valve seat 700 to adsorb the valve seat 700, and through the drive of the driving structure 300, the valve seat 700 is driven to move above the valve disc. The transportation process is relatively stable. When the valve seat 700 and the valve disc are installed, the adsorption structure 420 loses the power source, and the valve seat 700 will be slowly released to avoid damage to the valve seat 700 during the release process.

[0074] Please refer to Figure 2 and Figure 6 In an embodiment of the present utility model, the positioning assembly 500 includes:

[0075] The first driving member 510 is disposed on the stand 600;

[0076] The spring pieces 520 are provided in plurality and spaced apart in the circumferential direction. The first driving member 510 is drivingly connected to the spring pieces 520 to drive the spring pieces 520 to move in the radial direction, so that one end of the plurality of spring pieces 520 facing the axis abuts against the protruding column;

[0077] The valve seat 700 is arranged corresponding to the axis of the plurality of spring pieces 520 .

[0078] Specifically, each spring piece 520 corresponds to a fin, and the first driving member 510 drives the multiple first spring pieces 520 to move radially along the valve seat 700 to position the valve flap or release the valve flap. When the spring piece 520 moves radially toward the axis, one end toward the axis abuts against a fin, so that each fin is retracted inward to facilitate the projection into the through hole. When the projection is inserted into the through hole and the fin is matched with the limiting groove, the first driving member 510 drives the spring piece 520 to move radially away from the axis, and then releases the projection. At this time, the valve flap and the valve seat 700 are assembled together, wherein the multiple spring pieces 520 are spaced and evenly arranged along the circumferential direction, and the circumferential axis formed by the multiple spring pieces 520 is the same as the axis of the valve seat 700, so that when each spring piece 520 abuts against a fin, the projection corresponds to the through hole, which is convenient for positioning and assembling the valve flap.

[0079] During the specific implementation process, three spring pieces 520 are provided, corresponding to the three fins of the protruding column on the valve disc, and the three spring pieces 520 are arranged at intervals along the circumference of the valve seat 700, and move radially along the valve seat 700 under the drive of the first driving member 510, so that the three spring pieces 520 respectively correspond to the three fins of the protruding column on the valve disc, and push the three fins to retract inward.

[0080] Please refer to Figure 7 , in the embodiment of the present utility model, the first driving member 510 includes:

[0081] A rotary cylinder 511, which is arranged on the vertical frame 600;

[0082] A guide disk 512, which is arranged at the output end of the rotary cylinder 511. The rotary cylinder 511 drives the guide disk 512 to rotate. The guide disk 512 is circumferentially provided with a plurality of arc-shaped grooves 5121 at intervals;

[0083] A sliding column 513, which is connected to the elastic piece 520. A plurality of sliding columns 513 are provided, and each sliding column 513 is correspondingly arranged in an arc-shaped groove 5121, so that when the guide disk 512 rotates, the sliding column 513 and the elastic piece 520 move radially.

[0084] Specifically, the first driving member 510 includes a rotary cylinder 511, a guide disk 512 and a sliding column 513. The rotary cylinder 511 is installed at the bottom of the vertical frame 600, and the guide disk 512 is installed below the rotary cylinder 511. The rotary cylinder 511 drives the guide disk 512 to rotate. A plurality of arc-shaped grooves 5121 are arranged at intervals on the guide disk 512. One end of the arc-shaped groove 5121 is close to the axis, and the other end is far from the axis. The two ends of each arc-shaped groove 5121 are staggered in the radial direction. A sliding column 513 is slidably arranged in each arc-shaped groove 5121, and each sliding column 513 is correspondingly connected to an elastic piece 520. When the guide disk 512 rotates, it drives the arc-shaped groove 5121 to rotate, and then drives the sliding column 513 to slide in the arc-shaped groove 5121. Since the two ends of the arc-shaped groove 5121 are respectively close to or far from the axis and are staggered in the radial direction, the sliding column 513 moves radially along the guide disk 512 and drives the elastic piece 520 to move radially, close to or far from the axis, that is, it is convenient for the elastic piece 520 to abut against the fin when moving towards the axis and to make the fin fold inwards.

[0085] Please refer to Figure 6 and Figure 7 , in the embodiment of the present utility model, the positioning assembly 500 further includes:

[0086] A bracket 530, which is circumferentially arranged at intervals on the vertical frame 600;

[0087] A slider 540, which is fixedly arranged on the bracket 530;

[0088] A slide rail 550, which is slidably connected to the slider 540, and the slide rail 550 extends radially. The sliding column 513 and the elastic piece 520 are both installed on the slide rail 550.

[0089] Specifically, the positioning component 500 further includes a bracket 530, a slider 540, a slide rail 550, and a mounting block 560. The bracket 530 includes a first support plate and a second support plate. The first support plates are circumferentially spaced along the vertical frame 600 and extend in the vertical direction. The second support plate is disposed at one end of the first support plate away from the vertical frame 600 and is horizontally arranged. A slider 540 is fixedly provided on the top of the second support plate. The extending direction of the slider 540 is the radial direction of the guide disk 512. A slide rail 550 is slidably disposed above the slider 540. Two mounting blocks 560 are fixedly connected to the slide rail 550. The upper mounting block 560 is used to mount the sliding column 513, and the lower mounting block 560 is used to mount a spring piece 520. That is, when the guide disk 512 rotates, it drives the sliding column 513 to slide in the arc-shaped groove 5121. The sliding column 513 moves along the radial direction of the guide disk 512. By driving the mounting block 560, the slide rail 550 slides along the slider 540, which also drives the spring piece 520 to move along the radial direction of the guide disk 512. And a plurality of spring pieces 520 all move radially toward the axis of the guide disk 512, so that the spring pieces 520 abut against the fins of the valve flap and cause the fins to fold inward, facilitating the assembly of the valve flap and the valve seat 700.

[0090] In another embodiment, a slide rail 550 extending along the radial direction of the guide disk 512 is mounted on the second support plate. A slider 540 is slidably disposed on the slide rail 550. Two mounting blocks 560 are connected to the slider 540. The two mounting blocks 560 are respectively used to mount the sliding column 513 and the spring piece 520.

[0091] Please refer to Figure 2 、 Figure 3 and Figure 5 In the embodiment of the present utility model, the driving structure 300 includes:

[0092] A horizontal motion module 310, disposed on the base 200;

[0093] A lifting motion module 320, disposed on the horizontal motion module 310. The horizontal motion module 310 is drivingly connected to the lifting motion module 320. The suction component 400 and the positioning component 500 are both disposed on the lifting motion module 320. The lifting motion module 320 is drivingly connected to the suction component 400 and the positioning component 500.

[0094] Specifically, the driving structure 300 includes a horizontal motion module 310 and a vertical motion module. The horizontal motion module 310 and the vertical motion module cooperate to control the suction component 400 and the positioning component 500 to move in multiple directions, so as to drive the suction component 400 to bring the valve seat 700 close to the valve disc, and the valve seat 700 moves to the top of the valve disc. The positioning component 500 drives the valve disc to move and drives the fins of the valve disc to retract inward and assemble with the valve seat 700. The adsorption structure 420 releases the valve seat 700, so that the assembled valve seat 700 and the valve disc are transported to the next process for further assembly.

[0095] Please refer to Figure 2 and Figure 3 In an embodiment of the present utility model, the horizontal motion module 310 includes:

[0096] A linear telescopic member 311 is provided on the base 200;

[0097] The mounting plate 312 is slidably disposed on the base 200, the lifting motion module 320 is mounted on the mounting plate 312, and the output end of the linear telescopic member 311 is drivingly connected to a side of the mounting plate 312 away from the lifting motion module 320 to drive the mounting plate 312 to move along the first direction.

[0098] Specifically, the horizontal motion module 310 includes a linear telescopic member 311 and a mounting plate 312. The linear telescopic member 311 can adopt a structure that can realize linear drive, such as a cylinder, a hydraulic cylinder or an electric telescopic rod. The lifting motion module 320 is installed on the mounting plate 312. The mounting plate 312 is driven to slide along the base 200 by the linear telescopic member 311. In addition, the valve disc is placed on the assembly line and transported to the bottom of the base 200. The moving direction of the mounting plate 312 is the moving direction of the valve disc. Specifically, a sliding member is respectively arranged at both ends of the side of the mounting plate 312 facing the base 200, and a guide rail is respectively arranged on both sides of the top of the base 200. The sliding member is slidably connected to the guide rail. When the mounting plate 312 is driven to move by the linear telescopic member 311, the mounting plate 312 slides along the guide rail through the sliding member. Not only is the sliding more stable, but also the displacement during the sliding process can be avoided, thereby improving the assembly accuracy.

[0099] Please refer to Figure 3 and Figure 4 In an embodiment of the present utility model, the driving structure 300 further includes a buffer assembly 330, and the buffer assembly 330 includes:

[0100] The baffle 331 is provided on the base 200;

[0101] The buffer rod 332 is disposed on the baffle plate 331 . The buffer rod 332 has a buffer end. The buffer rod 332 extends along the first direction, and the buffer end faces the mounting plate 312 .

[0102] Specifically, a baffle 331 is respectively provided on both sides of the base 200, and the connecting line of the two baffles 331 is the movement direction of the lifting motion module 320. By respectively providing a buffer rod 332 on the two baffles 331, and the buffer end faces the mounting plate 312, when the mounting plate 312 slides on the base 200 along the first direction, the buffer rod 332 can provide a buffer for the movement of the mounting plate 312 to prevent the mounting plate 312 from sliding off the base 200 when moving. Specifically, the buffer end can be set to a rubber material to improve the buffering effect.

[0103] Please refer to Figure 5 In an embodiment of the present utility model, the lifting motion module 320 includes:

[0104] The lifting driving member 321 is disposed on a side of the mounting plate 312 away from the linear telescopic member 311;

[0105] The belt assembly 322 is drivingly connected to the lifting drive member 321;

[0106] The sliding block 323 is disposed on the belt assembly 322 , and the stand 600 is installed on the sliding block 323 .

[0107] Specifically, the lifting motion module 320 includes a lifting drive member 321, a belt assembly 322 and a sliding block 323. The belt assembly 322 is vertically arranged. The lifting drive member 321 can adopt a motor, etc., which drives the belt assembly 322 to move, and then drives the sliding block 323 on the belt assembly 322 to rise and fall. The stand 600 is installed on the side of the sliding block 323 away from the belt assembly 322. When the sliding block 323 slides, the stand 600 drives the suction assembly 400 and the positioning assembly 500 to rise and fall, so as to drive the suction assembly 400 and the positioning assembly 500 to approach the valve disc.

[0108] Please refer to Figure 5 In an embodiment of the present utility model, the driving structure 300 further includes:

[0109] A limiting piece 340 is provided on one side of the sliding block 323;

[0110] A plurality of position detectors 350 are provided, and the plurality of position detectors 350 are spaced apart on the mounting plate 312 along the vertical direction, and are used to detect the limiting piece 340 .

[0111] Specifically, a plurality of position detectors 350 are arranged on the mounting plate 312 and are spaced at intervals in the vertical direction. The limiting piece 340 is mounted on the sliding block 323. When the lifting driving member 321 drives the sliding block 323 to lift or lower, the limiting piece 340 passes by the position detector 350, so as to detect the position of the sliding block 323 through the position detector 350, that is, to judge the height of the positioning assembly 500 and the material suction assembly 400. Specifically, two position detectors 350 can be arranged. The limiting piece 340 moves between the upper and lower position detectors 350, and this moving range is also the moving range of the sliding block 323. When the upper position detector 350 detects the limiting piece 340, the motor stops starting at this time, and the sliding block 323 cannot rise any more, so as to avoid the continuous rotation of the belt assembly 322 causing the sliding block 323 to break away from the belt assembly 322 and affecting the operation of the equipment. Similarly, when the lower position detector 350 detects the limiting plate, the motor stops starting to prevent the continuous rotation of the belt assembly 322 and damaging the sliding block 323.
