Description

Technical Field

[0001] The invention belongs to the technical field of metal parts assembly, and in particular relates to a wave washer assembly device with a single-piece detection structure. Background Art

[0002] Wave washers are common mechanical components, specifically circular, wavy metal sheets with excellent elasticity and sealing properties. During assembly, these washers must first be inspected for defects such as cracks using an appearance inspection tool. Only qualified washers are then assembled onto components such as motor bearings.

[0003] However, in the process of conveying corrugated washers on the vibration plate, there are corrugated washers with two postures: concave downward and concave upward. It is difficult for existing equipment to effectively adjust the posture of the corrugated washers. The equipment lacks the function of single-piece inspection of corrugated washers, which makes it difficult to effectively detect the appearance defects of the corrugated washers. Defective corrugated washers may be assembled into the product, which increases the manual intervention steps and makes it difficult to achieve continuous and efficient inspection of assembly operations.

When the extrusion rod descends with the suction column, the extrusion rod will squeeze the inclined section to make the slide rod and the slide plate slide.

[0009] In one embodiment, the corrugated washer assembly device with a single-piece detection structure also includes a transmission mechanism, which includes a U-shaped tube. The bottom of the connecting frame is connected to the U-shaped tube filled with hydraulic oil. The two ends of the U-shaped tube are respectively slidably connected to piston rod 1 and piston rod 2. The end of piston rod 1 located outside the U-shaped tube is connected to vertical rod 1 between the translation column, and the end of piston rod 2 located outside the U-shaped tube is connected to vertical rod 2 between the slide plate.

[0010] In one embodiment, the corrugated gasket assembly equipment with a single-piece detection structure also includes a baffle, and the left end of the connecting frame is connected to the baffle located above the left end of the conveyor belt, and there is a gap between the bottom of the baffle and the top of the right end of the limiting plate for a single corrugated gasket to pass through.

[0012] In one embodiment, the wave washer assembly device with a single-piece detection structure further includes a collection frame, and the collection frame is connected to the rear side of the mounting platform.

[0013] The beneficial effects are: 1. The vibrating plate causes the corrugated gasket to move from the discharge port to the limiting plate, and the upwardly concave corrugated gasket moves along the limiting plate to the conveyor belt. The lower appearance detector detects the corrugated gasket, the suction column descends, the appearance detector moves forward, the suction column sucks the corrugated gasket and then rises, the appearance detector moves backward, and the upper appearance detector detects the corrugated gasket sucked by the suction column, thereby improving the detection accuracy.

[0029] refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7 The wave washer assembly equipment with a single-piece detection structure also includes a limiting mechanism, which includes a guide rod 101, a slide rod 102, an extrusion rod 104 and a slide plate 105. The top of the mounting platform 1 is fixedly connected to the guide rod 101, and a slide rod 102 that slides back and forth is provided on the guide rod 101. A compression spring is fixedly connected between the slide rod 102 and the guide rod 101. A slide plate 105 that slides back and forth is provided in the middle of the front side of the connecting frame 3. The slide plate 105 is used to limit the wave washer 20 directly below the appearance detector 7. The bottom end of the slide rod 102 is fixedly connected to the slide plate 105, and the top of the slide rod 102 has an inclined section 103. The middle of the suction column 9 is fixedly connected with the extrusion rod 104. When the extrusion rod 104 descends with the suction column 9, the extrusion rod 104 will squeeze the inclined section 103 to make the slide rod 102 and the slide plate 105 slide backward.

[0030] refer to Figure 7 and Figure 9 The corrugated washer assembly device with a single-piece detection structure also includes a transmission mechanism, which includes a U-shaped tube 111, a piston rod 112, a vertical rod 113, a piston rod 2 114 and a vertical rod 2 115.

The vertical rod 113 is fixedly connected between the end of the piston rod 112 located outside the U-shaped tube 111 and the translation column 6. The vertical rod 115 is fixedly connected between the end of the piston rod 2 114 located outside the U-shaped tube 111 and the slide plate 105.

[0031] refer to Figure 1 、 Figure 2 and Figure 4 The wave washer assembly device with a single-piece detection structure also includes a collection frame 13, and the collection frame 13 is fixedly connected to the rear side of the mounting platform 1.

[0032] Place the corrugated washer 20 to be inspected and assembled into the vibration plate 2, control the vibration of the vibration plate 2, and make the corrugated washer 20 move from the discharge port 21 to the limiting plate 5 in sequence. When the surface of the corrugated washer 20 on the limiting plate 5 is concave downward, as the vibration plate 2 vibrates, the corrugated washer 20 that is concave downward will slide off the limiting plate 5. When the surface of the corrugated washer 20 on the limiting plate 5 is concave upward, as the vibration plate 2 vibrates, the corrugated washer 20 that is concave upward gradually moves to the right along the limiting plate 5 to the conveyor belt 4, and the conveyor belt 4 is controlled to convey the corrugated washer 20 that is concave upward to the right.

[0033] The upward concave corrugated gasket 20 is conveyed by the conveyor belt 4 to the bottom of the appearance detector 7, and the appearance detector 7 on the lower side is controlled to detect the appearance defects of the top surface of the corrugated gasket 20. The electric push rod 190 on the front side is controlled to drive the suction column 9 on the front side to descend, driving the squeezing rod 104 on the front side to descend. The squeezing rod 104 squeezes the inclined section 103, causing the slide bar 102 to slide backward, and the compression spring is compressed. The slide bar 102 drives the slide plate 105, the vertical rod 115 and the piston rod 114 to move backward. The piston rod 114 squeezes the hydraulic oil in the U-shaped tube 111, and the piston rod 112 is driven by the hydraulic oil. Moving forward, the piston rod 112 drives the vertical rod 113, the translation column 6 and the appearance detector 7 to move forward, so that the appearance detector 7 leaves the top of the corrugated gasket 20, and the front suction column 9 continues to descend until the curved surface 91 at the bottom of the suction column 9 contacts the top surface of the corrugated gasket 20 after the detection, and the docking tube 93 docks the external vacuum equipment to control the vacuum equipment to pump air, and the suction column 9 sucks the corrugated gasket 20 through the suction hole 92, and the slide 105 moving backward will limit the corrugated gasket 20 to avoid the corrugated gasket 20 from shifting during the suction process, so that the suction column 9 is aligned with the corrugated gasket 20.

[0034] When the suction column 9 sucks the corrugated washer 20, the front electric push rod 90 is controlled to make the front suction column 9 and the front extrusion rod 104 rise and reset. When the front extrusion rod 104 separates from the inclined section 103, the compression spring is restored, so that the slide bar 102, the slide plate 105, the vertical rod 115 and the piston rod 114 move forward and reset. Under the transmission of the hydraulic oil, the piston rod 112, the vertical rod 113, the translation column 6 and the appearance detector 7 move backward and reset. The next corrugated washer 20 on the conveyor belt 4 can continue to move to the bottom of the appearance detector 7. At this time, the bottom surface of the corrugated washer 20 sucked by the suction column 9 is detected by the appearance detector 7 on the upper side, so that the appearance of the corrugated washer 20 is detected in multiple directions by the two appearance detectors 7, thereby improving the accuracy of the detection result.

[0035] The detection result information of the two appearance detectors 7 is sent to the controller. If one of the appearance detectors 7 detects that there is a defect in the appearance of the corrugated gasket 20, the corrugated gasket 20 is unqualified. Under the transmission of the gear set 82, the controller will control the drive motor to drive the rotating frame 8 to rotate 180 degrees, driving the suction column 9 and the sucked corrugated gasket 20 to rotate 180 degrees together, so that the unqualified corrugated gasket 20 moves to the top of the collection frame 13, and controls the vacuum equipment to stop vacuuming. Under the action of gravity, the unqualified corrugated gasket 20 falls to the collection frame 13 for collection; while collecting the unqualified corrugated gasket 20, controlling another electric push rod 90 can enable the other suction column 9 to continue to suck the next corrugated gasket 20, thereby improving work efficiency.

[0036] If the two appearance detectors 7 do not detect any defects in the appearance of the corrugated washer 20, the corrugated washer 20 is qualified. The controller will control the drive motor to rotate the rotating frame 8, the suction column 9 and the sucked corrugated washer 20 counterclockwise by 90 degrees, so that the qualified corrugated washer 20 is moved to the top of the assembly station, and the electric push rod 90 is controlled to drive the suction column 9 to descend, driving the corrugated washer 20 to descend onto the part, and then the vacuum equipment is controlled to stop vacuuming, the suction column 9 stops sucking the corrugated washer 20, and the electric push rod 90 drives the suction column 9 to rise and reset, thereby completing the assembly of the corrugated washer 20. In this way, the appearance defects of the single-piece corrugated washer 20 can be automatically and effectively detected, and the corrugated washer 20 can be assembled through the suction column 9, realizing continuous and efficient detection of assembly operations with high work efficiency.

[0037] Example 2: Based on Example 1, refer to Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 and Figure 10 The corrugated gasket assembly equipment with a single-piece detection structure also includes a baffle 121. The left end of the connecting frame 3 is fixedly connected to the baffle 121 located above the left end of the conveyor belt 4. There is a gap 125 between the bottom of the baffle 121 and the top of the right end of the limiting plate 5 for a single corrugated gasket 20 to pass through; the corrugated gasket assembly equipment with a single-piece detection structure also includes a connecting frame 122, an electric push rod 123 and a push plate 124. The top of the mounting table 1 is bolted with a connecting frame 122, and the connecting frame 122 is bolted with an electric push rod 123. The telescopic rod of the electric push rod 123 is connected with a push plate 124. The electric push rod 123 is used to drive the push plate 124 to move horizontally to the right front, and the push plate 124 pushes the corrugated gasket 20 on the limiting plate 5 to the gap 125.

[0038] The gap 125 between the baffle 121 and the limiting plate 5 is only for a single corrugated washer 20 to pass through, preventing two overlapping corrugated washers 20 from entering the conveyor belt 4. The electric push rod 2 123 is controlled to drive the push plate 124 to move horizontally to the right front. The push plate 124 pushes the corrugated washer 20 on the lower side of the two overlapping corrugated washers 20 into the gap 125, thereby preventing the two overlapping corrugated washers 20 from being unable to separate, ensuring the smooth progress of adsorption and detection work.
