[0056] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0057] The present application discloses an automated device for assembling a collar, used to assemble a collar 02 onto a connector 01. As shown in FIG12 , connector 01 comprises a housing 011 and a wire seal 012 located within housing 011. A gap exists between the opening of housing 011 and wire seal 012, forming a slot. Collar 02 is positioned within the slot, with an interference fit within the opening of housing 011. One end of collar 02 has a step, which engages within the slot. Because the outer diameter of collar 02 is larger than the inner diameter of the opening of housing 011, directly pressing collar 02 into the opening of housing 011 would wear it out. This wear would also create excess material in the gap between the opening of housing 011 and wire seal 012 on the inner or outer walls of housing 011, impacting the quality of connector 01. The present application's automated device for assembling collar 02 avoids this excess material and wear of collar 02.

[0058] The present application discloses an automated device for automatically assembling a collar, as shown in Figures 1, 2, and 11. The device comprises a frame having a human-machine control panel 211, a display screen 212, a chassis door 214, and a base plate 8. The base plate 8 is provided with a plate loading 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 collar transition mechanism 7, and a control terminal.

[0059] As shown in Figures 2 and 3, the tray loading mechanism 1 includes a first bracket 14, a first tray 11, a handle 12, and a proximity switch 13. The first bracket 14 is fixed to the device base plate 8, and the first tray 11 is placed on the first bracket 14. The handle 12 is fixed to the first tray 11, making it convenient for the operator to change trays. The proximity switch 13 is used to detect whether the first tray 11 is in place. The first tray 11, filled with collars, is manually placed on the first bracket 14 using the handle 12. The proximity switch 13 verifies whether the first tray 11 is in place.

[0060] As shown in Figures 2, 4, and 5, the product direction detection mechanism 2 includes a first fixed 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 bracket 22 is fixedly connected to the device base plate 8, and the first fixed block 21 is connected to the second bracket 22. The optical sensor 23 and the positioning block 26 are fixed to the first fixed block 21; the positioning block 26 has a horizontal movable hole, and the probe 27 is located in the movable hole. The positioning ring 24 is fixedly connected to the probe 27 via the positioning pin 25. The probe 27 is provided with a raised ring on the outside. The positioning ring 24 and the raised ring are respectively located on either side of the positioning block 26 to ensure that the probe 27 does not slip off the positioning block 26. The spring 28 is sleeved on the outside of 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 clamping ring to a fixed position in front of the probe 27, the clamping ring pushes the probe 27 to move horizontally. If the step part of the clamping 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-step part of the clamping 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.

[0061] The diameter of the stepped portion of the collar is larger than the diameter of the other portion. The correct position of the collar is with the platform at the bottom. To identify the upper and lower portions, ensure the smaller diameter end faces upward. The four-axis robot 4 clamps the collar and moves it to a fixed position in front of the probe 27. If the probe 27 shrinks inward, this indicates a larger diameter portion, which is the platform. This allows the user to determine whether the collar has the larger diameter platform at the bottom, ensuring the collar's orientation is correct. After the four-axis robot 4 grabs the part from the carrier mechanism 1, the product orientation detection mechanism 2 checks to see if it was missed or mis-grabbed. If mis-grabbed, the part (collar) is placed in the defective product receiving box 321.

[0062] As shown in Figures 2 and 6, 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 device base 8. The robot 43 is fixed to the device base 8 by connecting to the third bracket 45. The three-jaw chuck 44 is connected to the third axis of the robot 43 via the first connecting ring. The second servo motor drives the three-jaw chuck 44 to tighten and loosen the jaws.

[0063] As shown in Figures 2 and 7, 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 fixed plate 117, a pressure sensor 118, and a third fixed 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 via the first support plate 112. The first slide rail 116 is vertically arranged. The first slider 113 and the third fixed block 119 are both vertically slidably connected to the first slide rail 116, and the first slider 113 is located directly above the third fixed block 119. The third servo motor 111 is connected to the first support plate 112 and drives the first slider 113 to move up and down along the first slide rail 116. First fixing plate 117 is locked to first slider 113. The top of pressure sensor 118 is fixed to first fixing plate 117 via second connecting ring 114. The bottom of pressure sensor 118 is fixed to third fixing block 119. Compression sleeve 115 is connected to third fixing block 119 and is used to press the collar between the connector housing and the sealing body. When first slider 113 moves downward, it drives compression sleeve 115 vertically downward via pressure sensor 118 and third fixing block 119. Pressure sensor 118 can measure the pressure applied by compression sleeve 115, thereby enabling real-time monitoring of pressure during the insertion process.

[0064] As shown in Figures 2 and 8, the slide 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 connected to the second slide rail 53. The fourth servo motor 51 is connected to one end of the second slide rail 53 and 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 and is used to prevent the slide module 5 from exceeding the upper limit.

[0065] As shown in Figures 2 and 9, the shell clamping mechanism 6 includes a third slider 61, a third slide rail 62, a clamping claw 63, a platform base 64, and a third cylinder 65. The platform base 64 is fixed to the second slider 54. The third slide rail 62 and the third cylinder 65 are both connected to the surface of the platform base 64. Two third sliders 61 are provided, and both 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 move closer to or away from each other. Each third slider 61 is fixedly connected to a clamping claw 63. When the piston rod of the third cylinder 65 is actuated, it drives the third slider 61 to move back and forth along the third slide rail 62. The third slider 61 drives the clamping claws 63 to move closer to or away from each other, thereby clamping and loosening the connector shell.

[0066] As shown in Figures 2 and 10a, 10b, and 10c, the clamping 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 near the clamping jaw 63. The first cylinder 73 is fixed to the platform fixing plate 72. Two fourth slide rails 71 are provided, and both 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. The movement of the piston rod of the first cylinder 73 drives the movement of the fourth slider 75. A first connecting block 74 is fixed to the upper surface of the fourth slider 75. A transition mechanism 76 is fixed to the first connecting block 74. The transition mechanism 76 is used to accommodate a retaining ring. Movement of the piston rod of the first cylinder 73 drives both the fourth slider 75 and the transition mechanism 76, thereby moving the retaining ring placed on the transition mechanism 76 above the connector clamped by the clamping jaws 63. A limit block 77 is fixed to the upper surface of the platform fixing plate 72, near the platform base 64, to limit the range of movement of the fourth slider 75. A buffer 78 is fixed to the limit block 77 to act as a buffer when the fourth slider 75 collides with the limit block 77.

[0067] 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 connecting block 768. The second support plate 765 is fixedly connected to the end of the first connecting block 74 near 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 via the fifth slide rail 767. The fifth slider 763 is fixedly connected to the second connecting block 768. The second support plate 765 defines a vertical sliding slot. The second connecting block 768 passes through the sliding slot and is vertically slidably connected to the second support plate 765. The body of the second cylinder 766 is fixed to the second support plate 765. The piston rod of the second cylinder 766 is fixed to the second connecting block 768. Movement of the piston rod of the second cylinder 766 causes the fifth slider 763 and the second connecting block 768 to move vertically together. The fourth slider 75 is provided with an escape groove to allow the second cylinder 766 to pass through the fourth slider 75 from the position of the escape 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, and the two second fixed blocks 761 are fixedly connected to the two side edges of the first transition block 762 parallel to the horizontal movement direction of the first transition block 762. The second fixed blocks 761 are perpendicular to the first transition block 762 to prevent the first transition block 762 from bending during use. The second connecting block 768 is arranged in conjunction with the sliding groove, so that the second cylinder 766 and the first transition block 762 used for driving are respectively located on either side of the second support plate 765.

[0068] The first transition block 762 defines a transition hole 7621 that extends vertically through the first transition block 762. The transition hole 7621 comprises a straight section at the top and a tapered section at the bottom. The straight and tapered sections are coaxially arranged. The inner diameter of the straight section is larger than the outer diameter of the collar, while the inner diameter of the top of the tapered section is equal to that of the straight section, and the inner diameter of the bottom of the tapered section is smaller than the outer diameter of the collar. When the collar is placed in the straight section and forced out of the transition hole by the pressing device 4, the outer diameter of the collar is compressed by the inner wall of the tapered section, reducing its size. This allows the collar to enter the connector housing at a smaller size, thus preventing wear and the generation of excess material.

[0069] As shown in Figure 11, a through slot is provided at one end of the platform fixing plate 72 close to the platform base 64, and the through slot is located between the two fourth slide rails 71, so that the bottom of the second support plate 765 can move in the through slot, ensuring that the bottom of the second support plate 765 can extend downward more, ensuring that the first transition block 762 has sufficient downward vertical movement stroke to ensure that the first transition block 762 can be pressed against the top of the connector.

[0070] The control terminal automatically installs the clamps of the products to be assembled at multiple nodes according to the logic control signal of the control terminal.

[0071] The present invention is used as follows:

[0072] The four-axis robot 3 moves the collar from the first carrier 11 into the transition hole in the center of the first transition block 762. The piston rod of the first cylinder 73 shifts forward and backward, driving the first transition block 762 to move horizontally until the transition hole aligns with the product held by the clamp 63. The piston rod of the second cylinder 766 extends, driving the first transition block 762 downward to press the connector held by the clamp 63. The fourth servo motor 51 drives the second slider 54 to move, which in turn drives the first transition block 762 and the connector held by the clamp 63 to move together until the pressing sleeve 115 of the pressing device 4 aligns with the transition hole. The third servo motor 111 drives the first slider 113 to move, which in turn drives the pressing sleeve 115 downward, pressing the collar into the product slot. This prevents the generation of excess material and wear on the collar.
