Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly, in particular to a semi-automatic sealing ring assembly device. Background Art

[0002] A sealing ring is an accessory used for sealing.

[0003] Fig.16 The valve core 20 is shown, and a sealing ring 30 needs to be installed at the position of the annular groove 21 of the valve core 20. With the development of technology, equipment for automatically assembling sealing rings has emerged.

The jaws of the clamping jaws and the stripping jaws are staggered. After the clamping jaws clamp the outer O-ring to the top of the corresponding sealing ring, the stripping jaws push the outer O-ring downward to the outside of the sealing ring. The material taking position of the multi-claw support and clamping manipulator is provided with a lifting jaw that can push the outer O-ring upward. The lifting jaws correspond to the clamping jaws in an staggered manner, and the lifting jaws are driven by a cylinder.

DETAILED DESCRIPTION

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0039] like Figure 1 and Figure 2As shown, a sealing ring assembly device 10 includes a machine platform 100 and a feeding mechanism 200, a material picking mechanism 300, a material loading seat 400 and a material preparation component 500 respectively arranged on the machine platform 100, the feeding mechanism 200 is used to feed the sealing ring 30, the material loading seat 400 is used to support the valve core 20, the material picking mechanism 300 is used to transfer and assemble the sealing ring 30 onto the valve core 20, the material preparation component 500 includes a material preparation seat 510, a lifting drive member 520, a lifting seat 530, a material pushing drive member 540, and a material pushing plate 550, the material preparation seat 510 is arranged on the machine platform 100, and the material preparation seat 510 is provided with mutually connected slide grooves 511 and lifting holes 512, one end of the slide groove 511 away from the lifting hole 512 is connected to the feeding mechanism 200, the lifting drive member 520 is arranged below the material preparation seat 510, the lifting seat 530 is arranged on the output shaft of the lifting drive member 520, and the lifting seat 530 is penetrated by the lifting hole 512, the pushing drive member 540 is arranged on the material preparation seat 510, the pushing plate 550 is slidably arranged in the slide groove 511, and the pushing plate 550 is connected with the output shaft of the pushing drive member 540, and the pushing drive member 540 is used to drive the pushing plate 550 to reciprocate between the feeding mechanism 200 and the lifting seat 530, so that the pushing plate 550 pushes the sealing ring 30 one by one onto the lifting seat 530.

[0040] Specifically, the material preparation seat 510 is fixedly mounted on the machine 100, a slide groove 511 is provided on the surface of the material preparation seat 510, and a lifting hole 512 is provided at a position corresponding to the end of the slide groove 511, and the lifting hole 512 is a structure that penetrates the material preparation seat 510. The position of the slide groove 511 away from the lifting hole 512 is used to connect with the feeding mechanism 200. Further, the lifting drive member 520 is mounted on the material preparation seat 510. In one embodiment, the lifting drive member 520 is a cylinder, and the lifting seat 530 is mounted on the output shaft of the lifting drive member 520, so that the lifting drive member 520 drives the lifting seat 530 to perform lifting motion. The push drive 540 is mounted on the material preparation seat 510. In one embodiment, the push drive 540 is also a cylinder. The push plate 550 is mounted on the output shaft of the push drive 540. The push drive 540 drives the push plate 550 to reciprocate along the slide groove 511, so that the sealing rings 30 sent by the feeding mechanism 200 are pushed one by one onto the lifting seat 530. Thus, the material taking mechanism 300 can pick up the sealing ring 30 from the lifting seat 530 and put it into the annular groove 21 of the valve core 20 placed on the material loading seat 400. In this way, compared with the existing method of transferring the sealing ring 30 by the vibration force of the vibration plate, the present application uses the push plate 550 to push and transfer the sealing ring 30 one by one, so that the sealing ring 30 can be smoothly loaded.

[0041] like Figure 2As shown, in one embodiment, a material clamping step 531 is provided on the top surface of the lifting seat 530, and the material clamping step 531 is used to support the sealing ring 30. In this way, the sealing ring 30 can be placed in the middle position of the lifting seat 530 through the material clamping step 531.

[0042] In one embodiment, the discharge end of the feeding mechanism 200 is located on one side of the chute 511. Thus, the discharge end of the feeding mechanism 200 and the push plate 550 are not located at the same position relative to the chute 511, but are located perpendicular to each other, so that the push plate 550 can smoothly push the sealing ring 30 discharged from the discharge end of the feeding mechanism 200 onto the lifting seat 530.

[0043] like Figure 2 As shown, in one embodiment, a material incoming sensor 560 is further provided on the material preparation seat 510 , and the material incoming sensor 560 is located on the side of the slide 511 away from the feeding mechanism 200 , and the material incoming sensor 560 is aligned with the discharge end of the feeding mechanism 200 .

[0044] Specifically, when the discharge end of the feeding mechanism 200 moves a sealing ring 30 into the chute 511, the incoming material sensor 560 sends an incoming material signal to the control system (PLC control system), thereby causing the control system to pause the feeding mechanism 200 from continuing to feed materials.

[0045] like Figure 3 As shown, in one embodiment, the material loading seat 400 includes a seat body 410, a material placing sensor 420 and an assembly sensor 430. The seat body 410 is disposed on the machine 100. A material placing groove for accommodating the valve core 20 is opened in the seat body 410. The material placing sensor 420 is disposed at the bottom of the material placing groove, and the detection end of the material placing sensor 420 is disposed toward the material placing groove. The assembly sensor 430 is disposed on one side of the seat body 410, and the detection end of the assembly sensor 430 is disposed toward the annular groove 21 of the valve core 20.

[0046] Specifically, the seat body 410 is installed on the machine 100 by screws, and a material placement groove is opened at the center position of the seat body 410, so that the valve core 20 can be adaptively loaded into the material placement groove. Further, a material placement sensor 420 is installed at the bottom of the material placement groove. When the valve core 20 is placed in place, the material placement sensor 420 can send a valve core 20 in place signal to the control system. Further, an assembly sensor 430 is also installed at a side position of the seat body 410. For example, the assembly sensor 430 is a laser sensor, and the laser sensor includes a transmitting device and a receiving device. The transmitting device and the receiving device are respectively located on both sides of the seat body 410, and the detection paths of the transmitting device and the receiving device pass through the annular groove 21 of the valve core 20. In this way, when the sealing ring 30 is successfully assembled into the annular groove 21, the laser light path of the transmitting device is blocked, so that the control system receives a signal that the assembly is completed.

[0047] like Figure 1 and Figure 4 As shown, in one embodiment, the material picking mechanism 300 includes a bracket 310, a material picking module 320 and a material picking clamp 330. The bracket 310 is arranged on the machine 100, the material picking module 320 is arranged on the bracket 310 with an adjustable height, and the material picking clamp 330 is arranged on the output shaft of the material picking module 320. The material picking module 320 is used to drive the material picking clamp 330 to reciprocate between the lifting seat 530 and the loading seat 400.

[0048] Specifically, the bracket 310 is mounted on the machine 100, the material picking module 320 is mounted on the bracket 310, and the material picking clamp 330 is mounted on the material picking module 320, wherein the material picking module 320 is a driving structure capable of performing horizontal lateral movement and lifting movement at the same time. For example, the material picking module 320 can be a dual-axis robot, so that the material picking clamp 330 can move back and forth between the lifting seat 530 and the material loading seat 400, so that the material picking clamp 330 can pick up the sealing ring 30 from the lifting seat 530 and put it on the valve core 20 placed on the material loading seat 400.

[0049] like Figure 4 As shown, in one embodiment, the bracket 310 includes an adjustment seat 311 and a horizontal plate 312 . The adjustment seat 311 is disposed on the machine 100 . The horizontal plate 312 is disposed on the output shaft of the adjustment seat 311 . The material taking module 320 is disposed on the horizontal plate 312 .

[0050] Specifically, for example, the adjustment seat 311 is a slide rail structure with a screw, the cross plate 312 is slidably installed on the slide rail, and the cross plate 312 is screwed to the screw. In this way, by manually rotating the screw, the cross plate 312 can be driven to slide on the slide rail, thereby adjusting the height position of the cross plate 312 relative to the machine 100.

[0051] like Figure 1 and Figure 4 As shown, in one embodiment, the material picking module 320 includes a transverse moving part 321 and a longitudinal moving part 322, the transverse moving part 321 is arranged on the transverse plate 312, and the longitudinal moving part 322 is arranged on the output shaft of the transverse moving part 321, so that the transverse moving part 321 drives the longitudinal moving part 322 to move horizontally, and the material picking clamp 330 is arranged on the output shaft of the longitudinal moving part 322, so that the longitudinal moving part 322 drives the material picking clamp 330 to move up and down.

[0052] Specifically, the transverse moving part 321 and the longitudinal moving part 322 are one of the cylinder and the screw rod structure driven by the motor. In this way, under the cooperation of the transverse moving part 321 and the longitudinal moving part 322, the material picking clamp 330 can perform transverse movement and lifting movement.

[0053] like Figure 1As shown, in one embodiment, a protective grating 600 is further disposed on the machine platform 100, and the protective grating 600 is disposed around the four sides of the material carrier 400. In this way, the safety of the equipment during operation can be improved.

[0054] like Figures 5 to 10 As shown, the material taking clamp 330 includes a tensioning assembly 3100 and a stripping assembly 3200. The tensioning assembly 3100 includes an inner cylinder 3110, a core shaft 3120, a clamping spring 3130 and a plurality of clamping blocks 3140. A first sliding cavity 31111 is provided in the inner cylinder 3110. The core shaft 3120 is slidably arranged in the first sliding cavity 31111. One end of each clamping block 3140 is rotatably connected to the inner cylinder 3110, and each clamping block 3140 is equiangularly divided around the inner cylinder 3110. Each clamping block 3140 is also rotatably connected to the core shaft 3120, and the clamping spring 3130 is respectively in contact with the core shaft 3120 and the inner cylinder 3110. The clamping spring 3130 is used to push the core shaft 3120 so that the core shaft 3120 drives the ends of each clamping block 3140 away from the inner cylinder 3110 to move closer to each other. When air pressure is injected into the first sliding cavity 31111, the core shaft 3120 drives the ends of each clamping block 3140 away from the inner cylinder 3110 to move away from each other to open the sealing ring 30.

[0055] It should be noted that the tensioning assembly 3100 is used to open the sealing ring 30 in a natural state. Specifically, the core shaft 3120 is arranged coaxially with the inner cylinder 3110, and a first sliding cavity 31111 is opened in the axial direction of the inner cylinder 3110. One end of the core shaft 3120 is slidably arranged in the first sliding cavity 31111. One end of each clamping block 3140 is rotatably connected to the bottom end of the inner cylinder 3110. For example, the clamping block 3140 is installed on the inner cylinder 3110 through a bearing, so that the clamping block 3140 can rotate relative to the inner cylinder 3110. The clamping blocks 3140 are distributed at equal angles on the outer side wall of the inner cylinder 3110, that is, the angles between any two adjacent clamping blocks 3140 are consistent. Further, the middle part of each clamping block 3140 is also rotatably connected to the core shaft 3120. For example, the clamping block 3140 and the core shaft 3120 are also fixed by a bearing. The clamping spring 3130 is sleeved on the outer wall of the core shaft 3120, and the clamping spring 3130 is respectively in contact with the core shaft 3120 and the inner cylinder 3110. In this way, under the elastic thrust of the clamping spring 3130, the core shaft 3120 drives the free ends of the clamping blocks 3140 (the free ends of the clamping blocks 3140 refer to the ends away from the ends connected to the inner cylinder 3110) to move closer to each other. It should be noted that when the free ends of the clamping blocks 3140 move closer to each other to the limit position, the maximum distance between the clamping blocks 3140 is less than the inner diameter of the sealing ring 30 in the natural state. In this way, when the clamping blocks 3140 move closer to each other, the clamping blocks 3140 can pass through the sealing ring 30. When compressed air is injected into the first sliding cavity 31111 by an external air compressor, the compressed air pushes the core shaft 3120 located in the first sliding cavity 31111, so that the core shaft 3120 pushes to compress the clamping spring 3130, thereby causing the free ends of each clamp block 3140 to move away from each other, thereby causing each clamp block 3140 to open the sealing ring 30 in a natural state, and the sealing ring 30 is in an open state at this time. In one embodiment, five clamp blocks 3140 are provided, so that the sealing ring 30 is opened by the free ends of the five clamp blocks 3140, and the sealing ring 30 is in a pentagonal structure.

[0056] like Figure 5 As shown, the stripping assembly 3200 includes an outer cylinder 3210 and a stripping spring 3220. A second sliding cavity 32111 is opened in the outer cylinder 3210. The inner cylinder 3110 is slidably set in the second sliding cavity 32111. The stripping spring 3220 is respectively in contact with the inner cylinder 3110 and the outer cylinder 3210. The stripping spring 3220 is used to push the inner cylinder 3110 so that one end of each clamping block 3140 away from the inner cylinder 3110 extends from the bottom end of the outer cylinder 3210. When air pressure is injected into the second sliding cavity 32111, the inner cylinder 3110 drives one end of each clamping block 3140 away from the inner cylinder 3110 to retract into the bottom end of the outer cylinder 3210, so that the bottom end of the outer cylinder 3210 pushes out the opened sealing ring 30 of each clamping block 3140.

[0057] It should be noted that the inner cylinder 3110 is coaxially installed in the second sliding cavity 32111. The stripping spring 3220 is respectively in contact with the inner cylinder 3110 and the outer cylinder 3210, so that the inner cylinder 3110 slides relative to the outer cylinder 3210 under the elastic thrust of the stripping spring 3220, and then the inner cylinder 3110 drives the free ends of each clamping block 3140 to extend from the bottom end of the outer cylinder 3210. When compressed air is injected into the second sliding cavity 32111 by an external air compressor, the inner cylinder 3110 pushes and compresses the stripping spring 3220, and the inner cylinder 3110 drives each clamping block 3140 to retract into the outer cylinder 3210. In this way, by first injecting compressed air into the first sliding cavity 31111, the free end of each clamping block 3140 opens the sealing ring 30, and then injecting compressed air into the second sliding cavity 32111, each clamping block 3140 drives the sealing ring 30 to slide into the bottom end of the outer cylinder 3210. In this process, the bottom end of the outer cylinder 3210 pushes out the opened sealing ring 30 on each clamping block 3140. It should be noted that when the outer cylinder 3210 is regarded as fixed, the inner cylinder 3110 drives each clamping block 3140 to retract from the bottom end of the outer cylinder 3210. When the inner cylinder 3110 is regarded as fixed, it is equivalent to the outer cylinder 3210 being sleeved on the outside of each clamping block 3140 and extending out. Therefore, when each clamping block 3140 is docked with the workpiece to be installed, by injecting compressed air into the first sliding cavity 31111 and the second sliding cavity 32111 in sequence, the sealing ring 30 can be opened and assembled on the workpiece to be installed.

[0058] like Figure 6 , Fig. 9 and Fig.10 As shown, in one embodiment, the inner cylinder 3110 includes a cylinder body 3111 and a hinge sleeve 3112 , the first sliding cavity 31111 is located in the cylinder body 3111 , and the hinge sleeve 3112 is threadedly connected in the first sliding cavity 31111 .

[0059] It should be noted that the inner cylinder 3110 is configured as a combination structure of a cylinder body 3111 and an articulated sleeve 3112 , so that one end of the core shaft 3120 slides in the first sliding cavity 31111 , and the articulated sleeve 3112 confines the core shaft 3120 in the first sliding cavity 31111 .

[0063] Specifically, each protrusion 3113 is protrudingly disposed on the outer side wall of the hinge sleeve 3112, and each protrusion 3113 is distributed at an equal angle. By passing the pin through the clamping block 3140 and the protrusion 3113 in sequence, the clamping block 3140 can rotate relative to the protrusion 3113.

[0064] like Fig. 9 As shown, in one embodiment, a plurality of support blocks 3123 distributed at equal angles are provided on the outer side wall of the hinge joint 3122 , and each clamping block 3140 is rotatably connected to each support block 3123 .

[0067] Specifically, by passing a pin through one end of the clamp arm 3141 and the protrusion 3113 in sequence, one end of the clamp arm 3141 can rotate relative to the protrusion 3113. Further, by passing a pin through one end of the transfer arm 3142 and the support block 3123 in sequence, one end of the transfer arm 3142 can rotate relative to the support block 3123. Further, the other end of the transfer arm 3142 is rotatably connected to the middle position of the clamp arm 3141 by passing a pin, so that the other end of the transfer arm 3142 can rotate relative to the middle position of the clamp arm 3141. In this way, when the shaft body 3121 slides into the first sliding cavity 31111, the ends of each clamp arm 3141 away from the protrusion 3113 can eventually approach each other. When compressed air is injected into the first sliding cavity 31111 , the shaft body 3121 compresses the clamping spring 3130 and slides in the opposite direction, eventually making the ends of the clamping arms 3141 away from the protrusion 3113 move away from each other, thereby opening the sealing ring 30 .

In this way, when each clamping arm 3141 moves away from each other to open the sealing ring 30, the end of each clamping arm 3141 away from the protrusion 3113 is sunk into the air-avoiding groove 32131. When the clamping arm 3141 is retracted into the guide shell 3213, the lower end surface of the guide shell 3213 can push out the opened sealing ring 30 on each clamping arm 3141 to be assembled on the workpiece.

[0080] Specifically, the material tray 2100 is a cylindrical structure, and an inner cavity for installing the sealing ring 30 is provided in the material tray 2100, and a plurality of grooves 2110 are provided on the inner side wall and the inner bottom wall of the inner cavity. In one embodiment, the width of the groove 2110 is 2 mm to 4 mm, for example, the width of the groove 2110 can also be 3 mm.

It should be noted that since the grooves 2110 are provided on the inner side wall and the inner bottom wall of the material tray 2100, even if the surface of the sealing ring 30 is smeared with grease, it can effectively prevent the sealing ring 30 from being firmly adhered to the inner side wall / inner bottom wall of the material tray 2100, and when the stirring blade 2230 is stirred, the sealing ring 30 can be moved with it. In particular, since the sealing rings 30 are coated with grease, the sealing rings 30 are easily stuck together and knotted. Therefore, concave arc grooves 22321 are provided on both sides of the stirring blade 2230 to prevent the sealing rings 30 that are stuck together and knotted together from getting stuck during the stirring process, thereby ensuring that the stirring blade 2230 can stir the sealing rings 30 so that they fall into the discharge hole 2120 in an orderly manner to achieve feeding.
