Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0041] Please refer to Figures 1-10 , the present application provides a technical solution:

[0042] Embodiment 1:

[0043] A defective product re-inspection screening device, as shown in Figures 1 to 10 , includes a test part for screening the steel wire retainer main body 24 and a visual screening assembly, and the test part includes:

[0044] Stand 11: It is fixed on the top outer wall of the base 1 by bolts, and the top outer wall of the stand 11 is welded with a pad 10;

[0045] The accommodation protrusion 12 is welded to the bottom outer wall of the base plate 10, and the through hole opened on the surface of the accommodation protrusion 12 is slidably connected with the bent rod 18, and the top of the bent rod 18 is fixed with the inclined extrusion block 8 through a pin;

[0046] The spring 19 is sleeved on the outer wall of the bent rod 18, and the two ends of the spring 19 are respectively fixed to the inner wall of one side of the bent rod 18 and the outer wall of one side of the accommodation protrusion 12 through clamping;

[0047] The vertical plate 2 is fixed to the top outer wall of the base plate 10 through bolts;

[0048] The rotary rod 7 is rotatably connected to the inner wall of one side of the two vertical plates 2;

[0049] The drive motor 9 is fixed to the outer wall of one side of the vertical plate 2 through bolts, and the output end of the drive motor 9 is connected to one end of one of the rotary rods 7 through a shaft coupling;

[0050] The rotary plate 13 is welded between the two rotary rods 7;

[0051] The vertical plate two 21 is fixed to the top outer wall of the rotary plate 13 through bolts, and the outer wall of one side of the vertical plate two 21 is fixed with the electric telescopic rod one 22 through bolts, and the output end of the electric telescopic rod one 22 is fixed with the push rod 16 through a pin, and one end of the push rod 16 is fixed with the conical part matched with the inclined extrusion block 8;

[0052] The inclined plate 17 is welded to the circumferential outer wall of the push rod 16;

[0053] The extension plate 30 is welded to the outer wall of one side of the vertical plate two 21, and the surface of the extension plate 30 is provided with a pressure contact fixing mechanism matched with the inclined plate 17;

[0054] The base plate 10 and the rotary plate 13 are arranged to place the steel wire retainer ring body 24 to be screened, and the feeding mode of the steel wire retainer ring body 24 is preferably mechanical hand feeding. After placement, the electric telescopic rod one 22 drives the push rod 16 and the conical part to move horizontally, the conical part is inserted into the gap between the two inclined extrusion blocks 8 after continuous movement, the two inclined extrusion blocks 8 are expanded by the conical part, the straight line distance between the two inclined extrusion blocks 8 gradually increases, and the two inclined extrusion blocks 8 expand the gap of the steel wire retainer ring body 24 during movement to both sides. After the steel wire retainer ring body 24 is expanded, it deforms, and at the same time, the inclined plate 17 triggers the pressure contact fixing mechanism to move downward to fix the steel wire retainer ring body 24 during horizontal movement, and at this time, the steel wire retainer ring body 24 also deforms to a certain extent under the expansion of the inclined extrusion block 8;

[0055] In this embodiment, the outer wall of the oblique extrusion block 8 on one side is a slope. By setting the side surface as a slope, the contact between the oblique extrusion block 8 and the steel wire retainer body 24 is linear contact. After the steel wire retainer body 24 is fixed, the driving motor 9 is used to drive the rotating rod 7 and the rotating plate 13 to rotate. The rotating plate 13 drives the fixed steel wire retainer body 24 to move in a circular motion during rotation. Since the steel wire retainer body 24 and the oblique extrusion block 8 are in linear contact, the contact area between the steel wire retainer body 24 and the oblique extrusion block 8 can be effectively reduced during rotation. This avoids relative friction between the oblique extrusion block 8 and the steel wire retainer body 24 during the rotation of the steel wire retainer body 24 along the outer wall of the oblique extrusion block 8 on one side, which causes the end of the steel wire retainer body 24 to be severely worn. In this process, the tapered part rotates along the gap between the two oblique extrusion blocks 8, and the tapered part gradually separates from the two oblique extrusion blocks 8. When the tapered part completely separates from the oblique extrusion block 8, the spring 19 is used to reset the oblique extrusion block 8, so that the steel wire retainer body 24 gradually recovers from the deformed state to the normal state. When the steel wire retainer body 24 rotates 90 degrees, the steel wire retainer body 24 changes from a horizontal state to a vertical state. At this time, the visual screening assembly can be used for visual defect detection of the steel wire retainer body 24. The detection can be performed on whether the steel wire retainer body 24 returns to the state before deformation after being deformed by the oblique extrusion block 8. If the defect detection is the same as the state before deformation, the steel wire retainer body 24 is qualified. Otherwise, the steel wire retainer body 24 is unqualified and is screened out as unqualified products. The specific items of visual defect detection include the diameter of the steel wire retainer body 24 and the straight-line distance between the two ends of the steel wire retainer body 24.

[0056] Further, the crimping and fixing mechanism includes a U-shaped frame 25 and a T-shaped rod 28. The T-shaped rod 28 is slidingly connected to the inner wall of the through hole on the surface of the extension plate 30. The U-shaped frame 25 is fixed to the end of the T-shaped rod 28 through a pin. The U-shaped frame 25 has a roller 23 rotatingly connected to the inner wall, which cooperates with the oblique plate 17. The T-shaped rod 28 has a spring 20 sleeved on the outer wall. The two ends of the spring 20 are fixed to the bottom of the U-shaped frame 25 and the top outer wall of the extension plate 30 through clamping. The crimping and fixing mechanism further includes a pressure plate 15 and a pressure piece 26. The pressure piece 26 is welded to the bottom of the T-shaped rod 28. The pressure plate 15 is welded to one end of the pressure piece 26.

[0057] When the inclined plate 17 moves laterally, the inclined surface portion of the inclined plate 17 gradually contacts and presses downward the roller 23, and the pressing plate 26 and the pressing disc 15 press the top of the steel wire baffle body 24 during the downward movement, so that the steel wire baffle body 24 is pressed and fixed by the pressing plate 26 and the pressing disc 15. When the steel wire baffle body 24 rotates to a certain degree of deformation and is separated from the base plate 10, the part of the steel wire baffle body 24 originally fixed between the pressing disc 15 and the base plate 10 is reset due to the separation of the steel wire baffle body 24 from the base plate 10, so that the part of the steel wire baffle body 24 in contact with the pressing disc 15 is reset.

[0058] Further, the taper includes a rectangular plate 43 and a limiting rod 38, the rectangular plate 43 is welded at one end of the push rod 16, and the limiting rod 38 is threadedly connected to the outer wall of one side of the rectangular plate 43, the outer wall of the limiting rod 38 is slidingly connected with a guide plate 39, one end of the guide plate 39 is hingedly connected with an adjusting arm 40, and the end of the adjusting arm 40 away from the guide plate 39 is hingedly connected with a moving block 41, the outer wall of one side of the rectangular plate 43 is rotationally connected with a lead screw 3, and the surface of the moving block 41 is embedded with a nut matching the outer diameter of the lead screw 3, and one end of the lead screw 3 is welded with a knob 42.

[0059] Rotating the lead screw 3 makes the moving block 41 move linearly, and during the movement of the moving block 41, the lateral movement of the moving block 41 is converted into the linear movement of the guide plate 39 along the limiting rod 38 by the adjusting arm 40, and the inclination angle of the adjusting arm 40 can be adjusted within a certain range during this process. When it is necessary to expand the inclined extrusion block 8, the inner wall of the inclined extrusion block 8 can be extruded by the adjusting arm 40, so that the inclined extrusion block 8 moves under the extrusion of the adjusting arm 40 to expand the steel wire baffle body 24, so that the steel wire baffle body 24 is deformed.

[0060] Further, the visual screening assembly includes a vertical plate 4 and a mounting plate 5, the mounting plate 5 is welded to the top outer wall of the base 1, and the vertical plate 4 is fixed to the top outer wall of the mounting plate 5 by bolts, and the through hole formed in the surface of the vertical plate 4 is embedded with a visual defect detection probe 6.

[0061] During operation, the visual defect detection probe 6 is connected to the visual detection instrument through a wire harness, and after the visual defect detection probe 6 completes the visual defect detection of the steel wire baffle body 24, the detection data is transmitted to the visual detection instrument, and the visual detection instrument is used to process and analyze the screening results.

[0062] The embodiment is used when the steel wire check ring body 24 needs to be rechecked and screened. First, the mechanical hand is used to place the steel wire check ring body 24 on the base plate 10 and the rotating plate 13. Then, the inclination angle of the adjusting arm 40 of the conical part is adjusted. Then, the electric telescopic rod 22 is used to drive the push rod 16 and the inclined plate 17 to move laterally, so that the spring 20 extrudes the inner wall of the inclined extrusion block 8. The two inclined extrusion blocks 8 move to the sides after being extruded, extrude the notch of the steel wire check ring body 24, make the steel wire check ring body 24 deform, and in the process, the inclined surface of the inclined plate 17 extrudes the roller 23, so that the pressing sheet 26 and the pressing disc 15 move downward to fix the steel wire check ring body 24. When the steel wire check ring body 24 is fixed, the driving motor 9 is used to drive the rotating plate 13 and the steel wire check ring body 24 to rotate. When the steel wire check ring body 24 rotates 90°, the steel wire check ring body 24 and the visual defect detection probe 6 are in a directly opposite position. The visual defect detection probe 6 is used to detect the defects of the steel wire check ring body 24 by visual detection, so as to determine whether the steel wire check ring body 24 is qualified.

The adjusting rod 44 one side inner wall and the square plate 45 one side outer wall are fixed with a spring three 46 through a clamping mode. The adjusting rod 44 top is fixed with a V-shaped plate 36 through pins.

[0065] The electric telescopic rod two 34 can drive the V-shaped plate 36 to move laterally. When the steel wire check ring body 24 is placed on the surface of the base plate 10 and the rotating plate 13 by the mechanical hand, the electric telescopic rod two 34 can drive the sliding rod 37 to move forward and push the V-shaped plate 36 in the process. The spring three 46 elastically deforms in the process. The V-shaped plate 36 plays a role of pushing the steel wire check ring body 24, so that the notch of the steel wire check ring body 24 moves to the position of the two inclined extrusion blocks 8. When the electric telescopic rod two 34 drives the sliding rod 37 to move backward, the spring three 46 makes the V-shaped plate 36 reset.
