[0054] As used herein, the special term "exemplary" means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" herein need not be construed as superior to or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0055] An automatic device for automatic assembly of a snap ring of the present application is used to assemble the snap ring 02 onto the connector 01. As Figure 12 shown, the connector 01 includes a housing 011 and a cable sealing body 012 located inside the housing 011. There is a gap between the opening part of the housing 011 and the cable sealing body 012, and this gap is a card slot. The snap ring 02 is clamped in the card slot, and the snap ring 02 is in interference fit in the opening of the housing 011. One end of the snap ring 02 has a step, and the step part of the snap ring 02 is clamped into the card slot. Since the outer diameter of the snap ring 02 is larger than the inner diameter of the opening part of the housing 011, if the snap ring 02 is directly pressed into the opening of the housing 011, the snap ring 02 will be worn, and debris will be generated in the gap between the inner wall of the housing 011 or the outer wall of the snap ring 02 due to wear, which will affect the quality of the connector 01. An automatic device for automatic assembly of a snap ring 02 of the present application avoids the generation of the above-mentioned debris and the wear of the snap ring 02.

[0056] An embodiment of the present application discloses an automatic device for automatic assembly of a snap ring. As Figure 1 、 Figure 2 and Figure 11 shown, it includes an equipment frame, and the equipment frame is provided with a man-machine control panel 211, a display screen 212, a chassis door 214 and an equipment bottom plate 8. A carrier plate mechanism 1, a direction detection mechanism 2, a four-axis robot 3, a pressing device 4, a slide rail module 5, a housing clamping mechanism 6, a snap ring transition mechanism 7, and a control terminal are arranged on the equipment bottom plate 8.

[0057] As Figure 2 and Figure 3As shown in the figure, the carrier tray mechanism 1 includes a first support 14, a first carrier tray 11, a handle 12, and a proximity switch 13. The first support 14 is fixed on the equipment bottom plate 8, and the first carrier tray 11 is placed on the first support 14. The handle 12 is fixed on the first carrier tray 11, which enables the operator to conveniently replace the carrier tray. The proximity switch 13 is used to detect whether the first carrier tray 11 is placed in place. Manually, the first carrier tray 11 filled with snap rings is placed on the first support 14 through the handle 12, and the proximity switch 13 is used to identify whether the first carrier tray 11 is placed in place.

[0058] As Figure 2 , Figure 4 and Figure 5 shown in the figure, the product direction detection mechanism 2 includes a first fixing block 21, an optical sensor 23, a positioning ring 24, a positioning pin 25, a positioning block 26, a probe 27, and a spring 28. A second support 22 is fixedly connected to the equipment bottom plate 8, and the first fixing block 21 is connected to the second support 22. The optical sensor 23 and the positioning block 26 are fixed on the first fixing block 21; a horizontal moving hole is provided in the positioning block 26, the probe 27 is located in the moving hole, the positioning ring 24 is fixedly connected to the probe 27 through the positioning pin 25, a convex ring is provided outside the probe 27, and the positioning ring 24 and the convex ring are respectively located on both sides of the positioning block 26 to ensure that the probe 27 will not slip off the positioning block 26. The spring 28 is sleeved outside the probe 27, one end of the spring 28 is connected to the positioning block 26, and the other end is connected to the convex ring; when the four-axis robot 4 drives the clamped snap ring to a fixed position in front of the probe 27, the snap ring pushes the probe 27 to move horizontally. If the stepped part of the snap ring faces the probe 27, the moving distance of the probe 27 is large, and the probe 27 will block the sensing position of the optical sensor 23. If the non-stepped part of the snap ring faces the probe 27, the moving distance of the probe 27 is small, and the probe 27 will not block the sensing position of the optical sensor 23.

[0059] The diameter of the stepped part of the snap ring is larger than that of the other part. The correct position of the snap ring is that the stepped stage is at the bottom. It is necessary to identify the upper and lower parts, and then ensure that the end with the smaller diameter is upward. The four-axis robot 4 clamps the snap ring and moves it to a fixed position in front of the probe 27. If the probe 27 shrinks inward greatly, it means that the diameter of this part is large, so this part is the stepped stage, and thus it can be determined whether the stepped stage with the larger diameter of the snap ring is at the bottom to ensure that the direction of the snap ring is correct. After the four-axis robot 4 grabs the parts from the carrier tray mechanism 1, the product direction detection mechanism 2 is used to detect whether the parts are missed or grabbed in the reverse direction. If it is grabbed in the reverse direction, the parts (snap rings) will be put into the defective product receiving box 321.

[0060] As Figure 2 and Figure 6As shown, the four-axis robot 3 includes a second servo motor, a first connecting ring, a robot 43, and a three-jaw chuck 44. A third bracket 45 is fixedly connected to the equipment base plate 8. The robot 43 is fixed to the equipment base plate 8 by connecting with the third bracket 45. The three-jaw chuck 44 is connected to the third axis of the robot 43 through the first connecting ring. The clamping and loosening of the jaws are realized by driving the three-jaw chuck 44 with the second servo motor.

[0061] As Figure 2 and Figure 7 shown, the pressing device 4 includes a third servo motor 111, a first support plate 112, a first slider 113, a second connecting ring 114, a pressing sleeve 115, a first slide rail 116, a first fixing plate 117, a pressure sensor 118, and a third fixing block 119. A fixed base 120 is fixedly connected to the equipment base plate 8. The first slide rail 116 is fixed to the fixed base 120 through the first support plate 112. The first slide rail 116 is vertically arranged. Both the first slider 113 and the third fixing block 119 are vertically slidably connected to the first slide rail 116, and the first slider 113 is located directly above the third fixing block 119. The third servo motor 111 is connected to the first support plate 112. The third servo motor 111 drives the first slider 113 to move up and down along the first slide rail 116. The first fixing plate 117 is locked to the first slider 113. The top of the pressure sensor 118 is fixed to the first fixing plate 117 through the second connecting ring 114. The bottom of the pressure sensor 118 is fixed to the third fixing block 119. The pressing sleeve 115 is connected to the third fixing block 119. The pressing sleeve 115 is used to press the snap ring between the housing and the wire sealing body of the connector. When the first slider 113 moves downward, the first slider 113 drives the pressing sleeve 115 to move vertically downward through the pressure sensor 118 and the third fixing block 119. The pressure sensor 118 can measure the pressure of the pressing sleeve 115, thereby realizing the real-time monitoring of the pressure during the pressing process.

[0062] As Figure 2 and Figure 8 shown, the slide rail module 5 includes a fourth servo motor 51, a limit sensor 52, a second slide rail 53, and a second slider 54. The second slide rail 53 is fixed to the equipment base plate 8. The second slider 54 is horizontally slidably connected to the second slide rail 53. The fourth servo motor 51 is connected to one end of the second slide rail 53. The fourth servo motor 51 is used to drive the second slider 54 to move back and forth along the second slide rail 53. The limit sensor 52 is fixed to the second slide rail 53 to prevent the slide rail module 5 from exceeding the upper limit.

[0063] As Figure 2 and Figure 9As shown, the housing clamping mechanism 6 includes a third slider 61, a third slide rail 62, a jaw 63, a platform base 64, and a third cylinder 65. The platform base 64 is fixed to the second slider 54. Both the third slide rail 62 and the third cylinder 65 are connected to the surface of the platform base 64. Two third sliders 61 are provided, and both of the two third sliders 61 are horizontally slidably connected to the third slide rail 62. The piston rod of the third cylinder 65 is connected to the third slider 61 to drive the two third sliders 61 to approach or move away from each other. Each third slider 61 is fixedly connected to a jaw 63. When the piston rod of the third cylinder 65 acts, it drives the third slider 61 to move back and forth left and right along the third slide rail 62, and the third slider 61 drives the jaws 63 to approach and move away from each other to clamp and release the housing of the connector.

[0064] As Figure 2 and Figure 10a , Figure 10b , Figure 10c As shown, the snap ring transition mechanism 7 includes a fourth slide rail 71, a platform fixing plate 72, a first cylinder 73, a first connecting block 74, a fourth slider 75, a transition mechanism 76, a limit block 77, and a buffer 78. The platform fixing plate 72 is fixed to the side of the platform base 64 close to the jaw 63. The first cylinder 73 is fixed to the platform fixing plate 72. Two fourth slide rails 71 are provided, and both of the two fourth slide rails 71 are fixed to the platform fixing plate 72. The fourth slider 75 is slidably connected to the fourth slide rail 71. The piston rod of the first cylinder 73 is connected to the fourth slider 75, and the movement of the piston rod of the first cylinder 73 drives the fourth slider 75 to move. The first connecting block 74 is fixed to the upper surface of the fourth slider 75, and the transition mechanism 76 is fixed to the first connecting block 74. The transition mechanism 76 is used to place the snap ring. The movement of the piston rod of the first cylinder 73 drives the fourth slider 75 and the transition mechanism 76 to move together to drive the snap ring placed on the transition mechanism 76 to move above the connector clamped by the jaws 63. A limit block 77 is fixed to one end of the upper surface of the platform fixing plate 72 close to the platform base 64 to limit the movement range of the fourth slider 75. The buffer 78 is fixed to the limit block 77 to play a buffering role when the fourth slider 75 collides with the limit block 77.

[0065] The transition mechanism 76 includes a second fixed block 761, a first transition block 762, a fifth slider 763, a second transition block 764, a second support plate 765, a second cylinder 766, a fifth slide rail 767, and a second connection block 768. The second support plate 765 is fixedly connected to the end of the first connection block 74 close to the platform base 64. The fifth slide rail 767 is fixedly connected to the second support plate 765. The fifth slider 763 is vertically slidably connected to the second support plate 765 through the fifth slide rail 767. The fifth slider 763 is fixedly connected to the second connection block 768. The second support plate 765 is provided with a vertical sliding groove. The second connection block 768 passes through the second support plate 765 from the sliding groove and is vertically slidably connected to the second support plate 765. The body of the second cylinder 766 is fixed on the second support plate 765, and the piston rod of the second cylinder 766 is fixed on the second connection block 768. The movement of the piston rod of the second cylinder 766 will drive the fifth slider 763 and the second connection block 768 to move vertically together. The fourth slider 75 is provided with an avoidance groove so that the second cylinder 766 can pass through the fourth slider 75 from the position of the avoidance groove. The second transition block 764 is fixedly connected to the fifth slider 763. The second fixed block 761 and the first transition block 762 are connected to the second transition block 764. Two second fixed blocks 761 are provided. The two second fixed blocks 761 are fixedly connected to the two side edges of the first transition block 762 parallel to its own horizontal movement direction, and the second fixed block 761 is perpendicular to the first transition block 762 to prevent the first transition block 762 from bending during use. The cooperation between the second connection block 768 and the sliding groove enables the driving second cylinder 766 and the first transition block 762 to be located on both sides of the second support plate 765 respectively.

[0066] The first transition block 762 is provided with a transition hole 7621 vertically penetrating the first transition block 762. The upper part of the transition hole 7621 is a straight hole section, and the lower part is a tapered hole section. The straight hole section and the tapered hole section are coaxially arranged. The inner diameter of the straight hole section is larger than the outer diameter of the snap ring. The inner diameter of the top of the tapered hole section is equal to the inner diameter of the straight hole section, and the inner diameter of the bottom of the tapered hole section is smaller than the outer diameter of the snap ring. The snap ring is placed in the straight hole section. When the snap ring is pressed out of the transition hole by the pressing device 4, the outer diameter of the snap ring is squeezed by the inner wall of the tapered hole section and its size is reduced, so that it can enter the connector housing with a smaller size, thus avoiding the wear of the snap ring and the generation of debris.

[0067] As Figure 11 shown, one end of the platform fixing plate 72 close to the platform base 64 is provided with a through groove, and the through groove is located between the two fourth slide rails 71, so that the bottom of the second support plate 765 can move in the through groove, ensuring that the bottom of the second support plate 765 can extend downward more, ensuring that the first transition block 762 has enough vertical downward movement stroke to ensure that the first transition block 762 can be pressed tightly on the top of the connector.

[0068] The control terminal automatically installs the snap ring for the to-be-assembled products of multiple nodes according to the logical control signal of the control end.

[0069] The present invention is used as follows:

[0070] The four-axis robot 3 moves the snap ring from the first carrier 11 to the transition hole in the center of the first transition block 762. The piston rod of the first cylinder 73 moves back and forth, and the piston rod of the first cylinder 73 drives the first transition block 762 to move horizontally until the transition hole is aligned with the product clamped by the gripper 63. The piston rod of the second cylinder 766 extends to drive the first transition block 762 to press down and hold the connector clamped by the gripper 63. The fourth servo motor 51 drives the second slider 54 to move, and the second slider 54 drives the first transition block 762 and the connector clamped by the gripper 63 to move together until the bushing 115 of the pressing device 4 is aligned with the transition hole. The third servo motor 111 drives the first slider 113 to move and further drives the bushing 115 to move down, and the bushing 115 presses the snap ring into the product card slot. This avoids the generation of foreign matters and the wear of the snap ring.
