[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. By setting a conical part of the force-applying component, the two oblique extrusion blocks can be expanded from the inside. During the expansion process, the two oblique extrusion blocks squeeze the notch of the wire retaining ring body to both sides, so that it is convenient to use the visual screening component to detect whether there are defects in the wire retaining ring body after it returns to a normal state after deformation. In this way, the resilience performance of the wire retaining ring body can be screened.

[0024] 2. By setting the inclination angle of the adjusting arm of the force-applying component to be adjusted within a certain range, the expansion distance of the two oblique extrusion blocks can be adjusted under the condition that the crimping fixing mechanism moves downward by a certain distance, thereby limiting the degree of deformation of the wire retaining ring body.

[0025] 3. By setting up a rotating component, the wire retaining ring body can be driven to rotate after being fixed. By adjusting the rotation angle of the wire retaining ring body, the wire retaining ring body can be inspected for defects and unloaded after inspection during rotation.

[0026] 4. The contact between the oblique extrusion block and the wire retaining ring body is set to line contact. After the wire retaining ring body is fixed, the rotating plate drives the fixed wire retaining ring body to do circular motion during rotation. Since there is line contact between the wire retaining ring body and the oblique extrusion block, the contact area between the wire retaining ring body and the oblique extrusion block can be effectively reduced during the rotation of the wire retaining ring body, thereby avoiding relative friction between the oblique extrusion block and the wire retaining ring body during the rotation of the wire retaining ring body along the outer wall of one side of the oblique extrusion block, resulting in greater wear on the end of the wire retaining ring body.

[0027] 5. By setting the folding hole as two inclined holes and one straight hole, when the toggle column moves along the straight hole, the V-shaped plate is driven to move, and the wire retaining ring body is pushed to the side direction of the two inclined extrusion blocks. When the toggle column moves along the inclined hole, the arc push block and the offset rod move to the left or right to screen the qualified or unqualified wire retaining ring bodies from different directions.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-10 , the present invention provides a technical solution:

[0042] Embodiment 1:

[0043] A defective product re-inspection and screening device, such as Figures 1 to 10 As shown, it includes a testing part and a visual screening component for screening the wire retaining ring body 24, and the testing part includes:

[0044] The column 11 is fixed to the top outer wall of the base 1 by bolts, and a pad 10 is welded to the top outer wall of the column 11;

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

[0046] Spring 19: It 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 accommodating protrusion 12 by means of clamping;

[0047] Vertical plate 2: It is fixed to the top outer wall of the pad 10 by bolts;

[0048] Rotating rod 7: two rotating rods 7 are rotatably connected to the inner wall of one side of two vertical plates 2 respectively;

[0049] Driving motor 9: It is fixed to the outer wall of one side of the vertical plate 2 by bolts, and the output end of the driving motor 9 is connected to one end of one of the rotating rods 7 through a coupling;

[0050] Rotating plate 13: It is welded between the two rotating rods 7;

[0051] Vertical plate 21: It is fixed to the outer wall of the top of the rotating plate 13 by bolts, and an electric telescopic rod 22 is fixed to the outer wall of one side of the vertical plate 21 by bolts, and a push rod 16 is fixed to the output end of the electric telescopic rod 22 by a pin, and a conical piece adapted to the oblique extrusion block 8 is fixed to one end of the push rod 16;

[0052] Inclined plate 17: welded to the outer circumferential wall of the push rod 16;

[0053] Extension plate 30: It is welded to the outer wall of one side of the vertical plate 21, and a crimping fixing mechanism used in conjunction with the inclined plate 17 is installed on the surface of the extension plate 30;

[0054] By providing the pad 10 and the rotating plate 13, the wire retaining ring body 24 that needs to be screened can be placed. The wire retaining ring body 24 is preferably fed by a manipulator. After placement, the electric telescopic rod 22 is used to drive the push rod 16 and the tapered member to move horizontally. The tapered member is inserted into the gap between the two oblique extrusion blocks 8 after continuous movement. The two oblique extrusion blocks 8 are expanded by the tapered member, so that the straight-line distance between the two oblique extrusion blocks 8 gradually increases. The two oblique extrusion blocks 8 expand the notch of the wire retaining ring body 24 in the process of moving to both sides. The wire retaining ring body 24 is deformed after being expanded. At the same time, the oblique plate 17 triggers the crimping fixing mechanism to move down to fix the wire retaining ring body 24 in the process of lateral movement. At this time, the wire retaining ring body 24 is also deformed to a certain extent under the expansion of the oblique extrusion block 8.

[0055] In this embodiment, the outer wall of one side of the oblique extrusion block 8 is an inclined surface. By setting its side surface as an inclined surface, the contact between the oblique extrusion block 8 and the wire retaining ring body 24 is in line contact. After the wire retaining ring 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 wire retaining ring body 24 to make a circular motion during the rotation. Since there is a line contact between the wire retaining ring body 24 and the oblique extrusion block 8, the contact area between the wire retaining ring body 24 and the oblique extrusion block 8 can be effectively reduced during the rotation of the wire retaining ring body 24 along the outer wall of one side of the oblique extrusion block 8, thereby avoiding relative friction between the oblique extrusion block 8 and the wire retaining ring body 24, resulting in greater wear on the end of the wire retaining ring body 24, and the cone rotates along the gap between the two oblique extrusion blocks 8 during this process. The conical part also gradually detaches from the two oblique extrusion blocks 8. When the conical part is completely detached from the oblique extrusion block 8, the resilience of the spring 19 is used to reset the oblique extrusion block 8, so that the wire retaining ring body 24 gradually recovers from the deformed state to the normal state. When the wire retaining ring body 24 rotates 90 degrees, the wire retaining ring body 24 is transformed from a horizontal state to a vertical state. At this time, the visual screening component can be used to perform visual defect detection on the wire retaining ring body 24. After the wire retaining ring body 24 is deformed by the extrusion of the oblique extrusion block 8, it can be detected whether it has recovered to the state before deformation. If after the defect detection, it is the same as the state before deformation, then the wire retaining ring body 24 is qualified. Otherwise, the wire retaining ring body 24 is unqualified and is screened out as an unqualified product. The specific items of visual defect detection include the diameter of the wire retaining ring body 24 and the straight-line distance between the two ends of the wire retaining ring body 24.

[0056] Further, the crimping fixing mechanism includes a U-shaped frame 25 and a T-shaped rod 28, the T-shaped rod 28 is slidably connected to the inner wall of the through hole opened on the surface of the extension plate 30, and the U-shaped frame 25 is fixed to the end of the T-shaped rod 28 by a pin, and the inner wall of the U-shaped frame 25 is rotatably connected with a roller 23 used in conjunction with the inclined plate 17, the outer wall of the T-shaped rod 28 is sleeved with a spring 20, and the two ends of the spring 20 are fixed to the bottom of the U-shaped frame 25 and the outer wall of the top of the extension plate 30 by a clamping method, and the crimping fixing mechanism also includes a pressure plate 15 and a pressure sheet 26, the pressure sheet 26 is welded to the bottom of the T-shaped rod 28, and the pressure plate 15 is welded to one end of the pressure sheet 26;

[0057] When the inclined plate 17 moves laterally, the inclined surface of the inclined plate 17 gradually contacts the roller 23 and squeezes the roller 23 downward. The pressing piece 26 and the pressure plate 15 squeeze the top of the wire retaining ring body 24 during the downward movement. The pressing piece 26 and the pressure plate 15 can be used to press down and fix the wire retaining ring body 24. When the wire retaining ring body 24 rotates to a certain extent after deformation, the wire retaining ring body 24 detaches from the pad 10. The part of the wire retaining ring body 24 originally fixed between the pressure plate 15 and the pad 10 is reset because the wire retaining ring body 24 detaches from the pad 10, so that the part of the wire retaining ring body 24 in contact with the pressure plate 15 is reset.

[0058] Further, the conical member includes a rectangular plate 43 and a limit rod 38, the rectangular plate 43 is welded to one end of the push rod 16, and the limit rod 38 is connected to the outer wall of one side of the rectangular plate 43 by a thread, the outer wall of the limit rod 38 is slidably connected to a guide plate 39, and an adjustment arm 40 is hinged at one end of the guide plate 39, and a moving block 41 is hinged at one end of the adjustment arm 40 away from the guide plate 39, the outer wall of one side of the rectangular plate 43 is rotatably connected to the lead screw 3, and a nut matching the outer diameter of the lead screw 3 is embedded on the surface of the moving block 41, and a knob 42 is welded at one end of the lead screw 3;

[0059] The rotating screw 3 causes the moving block 41 to perform linear motion. During the movement of the moving block 41, the adjusting arm 40 is used to convert the lateral movement of the moving block 41 into linear motion of the guide plate 39 along the limit rod 38. During this process, the inclination angle of the adjusting arm 40 can be adjusted within a certain range. When it is necessary to expand the oblique extrusion block 8, the adjusting arm 40 can be used to extrude the inner wall of the oblique extrusion block 8, so that the oblique extrusion block 8 moves under the extrusion process of the adjusting arm 40 to expand the wire retaining ring body 24, causing the wire retaining ring body 24 to deform.

[0060] Furthermore, 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 a through hole opened on 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 wiring harness. After the visual defect detection of the wire retaining ring body 24 is completed using the visual defect detection probe 6, the detection data is transmitted to the visual detection instrument, and the screening results are processed and analyzed using the visual detection instrument.

[0062] When the present embodiment is in use, when it is necessary to re-inspect and screen the main body 24 of the wire retaining ring, the main body 24 of the wire retaining ring is first placed on the pad 10 and the rotating plate 13 by a manipulator, and then the inclination angle of the adjusting arm 40 of the conical member is adjusted, and then the electric telescopic rod 1 22 is used to drive the push rod 16 and the inclined plate 17 to move laterally, so that the spring 20 squeezes the inner wall of the inclined squeezing block 8, and the two inclined squeezing blocks 8 move to both sides at the same time after being squeezed to squeeze the notch of the main body 24 of the wire retaining ring, so that the main body 24 of the wire retaining ring is deformed, and this process During the process, the inclined surface of the inclined plate 17 squeezes the roller 23, so that the pressing piece 26 and the pressure plate 15 move down to fix the wire retaining ring body 24. When the wire retaining ring body 24 is fixed, the driving motor 9 is used to drive the rotating plate 13 and the wire retaining ring body 24 to rotate. When the wire retaining ring body 24 rotates 90°, the wire retaining ring body 24 and the visual defect detection probe 6 are in a facing position. The visual defect detection probe 6 is used to perform defect detection on the wire retaining ring body 24 by visual detection, so as to determine whether the wire retaining ring body 24 is qualified.

[0063] Embodiment 2:

[0064] A defective product re-inspection and screening device, such as Figures 1 to 10 As shown, in order to facilitate the blanking of qualified or unqualified wire retaining ring bodies 24; this embodiment makes the following supplements on the basis of embodiment 1: the top outer wall of the rotating plate 13 is fixed with a vertical plate 35 by bolts, and the outer wall of one side of the vertical plate 35 is fixed with an electric telescopic rod 2 34 by bolts and screws, and the output end of the electric telescopic rod 2 34 is fixed with a slide bar 37 by a pin, and the bottom outer wall of the rotating plate 13 is welded with a square plate 45, and the through hole opened on the surface of the square plate 45 is slidably connected with an adjusting rod 44, and a spring 3 46 is fixed between the inner wall on one side of the adjusting rod 44 and the outer wall on one side of the square plate 45 by a clamping method, and the top of the adjusting rod 44 is fixed with a V-shaped plate 36 by a pin;

[0065] By providing an electric telescopic rod 2 34, the V-shaped plate 36 can be driven to move horizontally. When the wire retaining ring body 24 is placed on the upper surface of the pad 10 and the rotating plate 13 by a manipulator, the electric telescopic rod 2 34 can be used to drive the sliding rod 37 to move forward to push the V-shaped plate 36. The spring 3 46 generates elastic deformation in this process, and the V-shaped plate 36 is used to push the wire retaining ring body 24, so that the notch of the wire retaining ring body 24 moves to the position on the sides of the two oblique extrusion blocks 8. When the electric telescopic rod 2 34 drives the sliding rod 37 to move backward, the rebound force of the spring 3 46 is used to reset the V-shaped plate 36.

[0066] Furthermore, it also includes a screening component, which includes a folded hole 31 opened on the rotating plate 13, and a connecting block 32 is welded to the outer wall of the slide rod 37, a lining plate 29 is welded to the outer wall of the top of the rotating plate 13, and a through hole opened on the surface of the lining plate 29 and a through hole opened on the surface of the connecting block 32 are slidably connected with the same offset rod 27, and arc-shaped push blocks 14 are welded at both ends of the offset rod 27, and a toggle column 33 used in conjunction with the inner diameter of the folded hole 31 is fixed to the bottom of the offset rod 27 by screws;

[0067] The fold line hole 31 is composed of two oblique holes and one straight hole. When the electric telescopic rod 23 drives the toggle column 33 to slide along the straight hole, the offset rod 27 will not be displaced in the lateral direction. The toggle column 33 is convenient for the V-shaped plate 36 to push the wire retaining ring body 24 during the sliding process along the straight hole, so that the notched part of the wire retaining ring body 24 moves to the side direction of the two oblique extrusion blocks 8. When the wire retaining ring body 24 needs to be unloaded after the visual screening component is used, the driving motor 9 is used to drive the wire retaining ring body 24 to rotate, so that the wire retaining ring body 24 moves to the side direction of the two oblique extrusion blocks 8. Fig.10 When the shift rod 27 and the arc push block 14 are moved to the left, the wire retaining ring body 24 is unloaded from the left side; when the shift rod 27 and the arc push block 14 are moved to the right, the wire retaining ring body 24 is unloaded from the right side. In this way, qualified or unqualified wire retaining ring bodies 24 can be unloaded from different directions, thereby realizing the screening of the wire retaining ring bodies 24.

[0068] In this embodiment, after the wire retaining ring body 24 is screened by the visual screening component, the drive motor 9 is used to drive the wire retaining ring body 24 to rotate to Fig.10 At the position shown, the output end of the electric telescopic rod 1 22 moves in the opposite direction, so that the crimping fixing mechanism is detached from the surface of the wire retaining ring body 24. At this time, the wire retaining ring body 24 is tilted under the action of gravity, and the pressure plate 15 limits the inclination amplitude of the wire retaining ring body 24 and at the same time acts as a barrier to the wire retaining ring body 24. At this time, depending on whether the wire retaining ring body 24 is qualified, the electric telescopic rod 2 34 drives the toggle column 33 to move along the corresponding inclined hole, and the arc push block 14 and the offset rod 27 move toward the left or right side to realize the unloading of qualified or unqualified wire retaining ring bodies 24.
