[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] like Figure 1-5 As shown, the utility model provides a sealing ring feeding and assembling device, comprising a vibrating material tray 1, a guide rail 2, a feeding mechanism 3, a conveying mechanism 4 and an assembling mechanism 5, the vibrating material tray 1 is used to hold and convey the sealing rings 6 one by one; the feeding end of the guide rail 2 is connected to the discharging end of the vibrating material tray 1, the discharging end of the guide rail 2 is connected to the feeding mechanism 3, and the conveying mechanism 4 conveys the sealing ring 6 from the feeding mechanism 3 to the assembling mechanism 5.

[0026] Through the coordinated action of the vibrating material plate 1, the guide rail 2, the feeding mechanism 3, the conveying mechanism 4 and the assembling mechanism 5, the vibrating material plate 1 transports the sealing rings 6 one by one and orderly to the feeding mechanism 3 through the guide rail 2, and the conveying mechanism 4 conveys the sealing rings 6 from the feeding mechanism 3 to the assembling mechanism 5 for assembly, so as to realize automatic feeding and assembly of the sealing rings 6, which can more effectively ensure the efficiency and quality of assembly than manual work and can meet the requirements of efficient and fast assembly.

[0027] Through the cooperation of the vibrating material tray 1 and the guide rail 2, the sealing ring 6 can be driven stably and orderly into the feeding mechanism 3, avoiding possible misoperation in manual taking and assembly. Among them, the vibrating material tray 1 and the guide rail 2 adopt the existing technology, which will not be described in detail here.

[0028] As an optional implementation, Figure 1 , 2 As shown in FIG. 3 , the feeding mechanism 3 includes a feeding block 31 and a feeding drive unit. The feeding block 31 is provided with a feeding groove 311 for receiving the sealing ring 6 ; the feeding drive unit drives the feeding block 31 to move.

[0029] Furthermore, there are multiple loading troughs 311 , which are arranged in sequence along the length direction of the loading block 31 , and the side close to the guide rail 2 is designed to be open, so that the sealing ring 6 can easily enter the loading trough 311 from the guide rail 2 .

[0030] It also includes a limit plate 36, which is arranged on the side of the material-retrieving position of the conveying mechanism 4 at the discharge end of the guide rail 2 and extends parallel to the length direction of the loading block 31 to the corresponding material-retrieving position of the conveying mechanism 4. When the loading block 31 moves toward the conveying mechanism 4, the loading block 31 abuts against the limit plate 36, closing the opening side of the loading slot 311, preventing the sealing ring 6 from detaching from the loading plate during the movement process, and ensuring the stability of the subsequent material-retrieving operation of the conveying mechanism 4.

[0031] As an optional implementation, Figure 1 , 2 As shown, the feeding drive unit includes a motor 32, a lead screw 33 and a nut slider 34. The output end of the motor 32 is transmission-connected to the lead screw 33, the lead screw 33 is transmission-matched to the nut slider 34, and the nut slider 34 is connected to the feeding block 31 through a feeding connecting plate 35.

[0032] Furthermore, the feeding mechanism 3 also includes a feeding base 37 , and the motor 32 is disposed on the feeding base 37 .

[0033] The motor 32 drives the lead screw 33 to rotate, so that the nut slider 34 moves along its axial direction, thereby driving the loading block 31 to reciprocate between the discharge end of the guide rail 2 and the material taking position of the conveying mechanism 4.

[0034] As the nut slider 34 moves, the loading block 31 is driven to move, so that each loading trough 311 moves to the discharge end sealing ring 6 of the guide rail 2 in turn, until all the loading troughs 311 receive the sealing ring 6, and then drive the loading block 31 to move to the material picking position of the conveying mechanism 4, and wait until the conveying mechanism 4 picks up the material.

[0035] As an optional implementation, Figure 1 , 2 As shown in FIG. 3 , an optical fiber sensor 38 is provided on the loading block 31 . The optical fiber sensor 38 is provided in a one-to-one correspondence with the loading trough 311 , and is used to detect whether a sealing ring 6 is placed in the loading trough 311 .

[0036] Furthermore, a mounting groove 312 is provided on the loading block 31 for placing the optical fiber sensor 38 . The mounting groove 312 is connected to the loading groove 311 so that the optical fiber sensor 38 can accurately detect whether the sealing ring 6 is placed in the loading groove 311 .

[0037] When the sealing ring 6 is correctly placed in the loading slot 311, the corresponding optical fiber sensor 38 transmits a signal to the control system, and the control system controls the motor 32 to drive the loading plate to move, so that the next loading slot 311 docks with the guide rail 2 to receive the sealing ring 6. Among them, the control system and the optical fiber sensor 38 adopt the existing technology.

[0038] As an optional implementation, Figure 1 , 4 As shown, the transport mechanism 4 includes a flipping cylinder 41, a moving cylinder 43, a material picking part and a material dividing part. The flipping cylinder 41 is connected to the fixed end of the moving cylinder 43 through a flipping frame 42, and the movable end of the moving cylinder 43 is connected to the material picking part through a moving connecting plate 44. The material dividing part is arranged on the moving connecting plate 44 and is used to drive the sealing ring 6 to separate from the material picking part.

[0039] Furthermore, the transport mechanism 4 also includes a transport base 48 , a fixed end of the flip cylinder 41 is disposed on the transport base 48 , and a rotating end of the flip cylinder 41 is connected to a fixed end of the moving cylinder 43 via a flip frame 42 .

[0040] The turning cylinder 41 drives the moving cylinder 43 , the material taking part and the material distributing part to turn over through the turning frame 42 , so that the material taking part drives the sealing ring 6 to turn over to the corresponding position of the assembly mechanism 5 .

[0041] The moving cylinder 43 drives the material picking part and the material dividing part to move along their axial direction, so that the material picking part can be inserted into and separated from the loading trough 311, and accurately pick up the sealing ring 6 on the loading block 31. It can also enable the material picking part to be inserted into and separated from the product body on the assembly mechanism 5, and accurately assemble the sealing ring 6 to the product body, so as to realize the assembly of the sealing ring 6 and the product body.

[0042] As an optional implementation, Figure 1 , 3 As shown in , 4, the material picking part includes a material picking needle 45, which is installed on the movable connecting plate 44. The diameter of the material picking needle 45 decreases from top to bottom. The material picking needle 45 is arranged in a one-to-one correspondence with the material loading trough 311, and the material loading trough 311 is provided with a groove 3111 for the material picking needle 45 to enter.

[0043] Furthermore, the diameter of the material picking end of the material picking needle 45 decreases from top to bottom to form a conical structure. By utilizing the elastic characteristics of the sealing ring 6, when the movable cylinder 43 drives the material picking needle 45 to insert into the groove 3111 of the loading trough 311, due to the conical structure of the material picking end, the material picking needle 45 can easily enter the sealing ring 6, and the elasticity of the sealing ring 6 enables it to fit tightly on the material picking needle 45. Then, the movable cylinder 43 drives the material picking needle 45 to drive the sealing ring 6 to separate from the loading trough 311, so as to realize the material picking operation of the sealing ring 6.

[0044] As an optional implementation, Figure 1 , 4 As shown, the material dividing part includes a material dividing cylinder 46 and a material dividing plate 47 . The material dividing cylinder 46 is arranged on the movable connecting plate 44 , and the material dividing plate 47 is sleeved on the material taking needle 45 . The material dividing cylinder 46 drives the material dividing plate 47 to reciprocate along the axis of the material taking needle 45 .

[0045] During the material taking process of the material taking part, the material dividing cylinder 46 is in a contracted state, and the material dividing plate 47 does not interfere with the normal material taking operation of the material taking needle 45 .

[0046] When the moving cylinder 43 drives the picking needle 45 to drive the sealing ring 6 to move to the position of the product body 7 corresponding to the assembly mechanism 5, the dividing cylinder 46 drives the dividing plate 47 to move toward the picking end of the picking needle 45 until it contacts the sealing ring 6. As the dividing plate 47 moves, the sealing ring 6 is pushed to separate from the picking needle 45 so that the sealing ring 6 can be accurately assembled on the product body 7.

[0047] As an optional implementation, Figure 1 , 5 As shown, the assembly mechanism 5 includes an assembly platform 51 and a positioning part. A positioning fixture 511 is provided on the assembly platform 51. The positioning part includes a lifting cylinder 52 and a clamping cylinder 54. The clamping cylinder 54 is arranged in a one-to-one correspondence with the positioning fixture 511. The lifting cylinder 52 is connected to the clamping cylinder 54 through a positioning plate 53.

[0048] Furthermore, the assembly mechanism 5 further includes an assembly base 55, the fixed end of the lifting cylinder 52 is connected to the assembly base 55, and the movable end of the lifting cylinder 52 is connected to the clamping cylinder 54 through the positioning plate 53. The assembly platform 51 is connected to the assembly base 55 through an assembly connector.

[0049] The positioning fixture 511 is arranged in one-to-one correspondence with the material taking part. The positioning fixture 511 is used to fix the product body.

[0050] The lifting cylinder 52 drives the clamping cylinder 54 to perform lifting motion so that the clamping cylinder 54 moves to a preset height.

[0051] When assembly is required, the lifting cylinder 52 drives the positioning plate 53 to descend, so that the clamping claws of the clamping claw cylinder 54 clamp the product body to prevent the product body 7 from moving during the assembly process, thereby ensuring the stability of the assembly process.
