DETAILED DESCRIPTION
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technical personnel in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0037] See also Figures 1 to 9 The present invention provides a technical solution: a rectifier bridge assembly device for an automotive AC generator, comprising an assembly cabinet 1, a slide groove 2 is provided on the lower side of the assembly cabinet 1, and a slide seat 3 is slidably connected in the slide groove 2, and an assembly groove 4 is provided at the bottom of the slide seat 3, an operating groove 5 is provided on the top of the assembly cabinet 1, and a baffle 6 is fixedly provided in the operating groove 5, a plurality of guide tubes 7 are fixedly installed on the baffle 6, and a plurality of elastic sheets 8 are distributed in an annular shape inside the guide tube 7, and the plurality of elastic sheets 8 are in a conical structure. The bottom plate and the shell of the rectifier bridge are placed in the assembly groove 4, and the slide seat 3 is pushed into the interior of the assembly cabinet 1, and then the bolts are placed along the guide tube 7. At this time, the elastic sheet 8 in the guide tube 7 supports the bolt and centers it on the mounting hole on the shell.
[0038] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, an arranger 9 is provided on the baffle 6, and the arranger 9 is used to automatically guide the bolts into the guide tube 7. The arranger 9 includes a through groove 91 opened along the middle of the baffle 6, and the baffle 6 is tilted along the inside of the assembly cabinet 1 with the left side higher and the right side lower.
[0039] A slope 92 that matches the through slot 91 is fixed at the high position of the baffle 6. When the bolt is placed on the slope 92, the bolt rolls into the through slot 91. At this time, the head of the bolt cannot enter the through slot 91 and is stuck. The screw falls into the through slot 91, causing the bolt to hang vertically and move from left to right along the through slot 91.
[0040] The surface of the baffle 6 is provided with a connecting groove 91 and a transverse groove 93 of the guide tube 7, and a magnetic seat 94 corresponding to the transverse groove 93 is fixedly provided on the top of the guide tube 7. When the bolt reaches the transverse groove 93, the magnetic seat 94 sucks the bolt into the guide tube 7.
[0041] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a releaser 10 is provided on the baffle 6 , the assembly cabinet 1 and the slide 3 , and the releaser 10 is used to control the bolts in the guide tube 7 to automatically fall when they are aligned in the assembly groove 4 .
[0042] The releaser 10 includes an inner groove 101 opened along the inside of the cabinet panel on the right side of the assembly cabinet 1, and a slide plate 102 is slidably connected to the inner groove 101. A spring 103 is provided in the inner groove 101, and the spring 103 pushes it to move toward the operating groove 5. The lower side of the inner groove 101 passes through the assembly cabinet 1 and is connected to the slide groove 2. A triangular block 104 is fixedly provided on the surface of the slide plate 102, and the triangular block 104 extends from the slide groove 2 to the inside of the slide groove 2.
[0043] A side groove 105 corresponding to the triangular block 104 is formed on the side surface of the slide 3 , and a protrusion 106 cooperating with the triangular block 104 is fixedly disposed in the side groove 105 .
[0044] A plate groove 107 is provided inside the baffle 6 and is connected to the guide tube 7 and the inner groove 101, and a clamping plate 108 for limiting the bolt is slidably connected in the plate groove 107. The clamping plate 108 extends into the inner groove 101 and is controlled by the slide plate 102. After the bolt is installed in the guide tube 7, it is clamped by the clamping plate 108.
[0045] A notch 109 is provided on the surface of the clamping plate 108 to match the guide tube 7, and the notch 109 and the guide tube 7 are staggered. After the slide 3 is pushed into the assembly cabinet 1, the protrusion 106 on the slide 3 squeezes the triangular block 104 and the slide plate 102 to move, and pulls the clamping plate 108 to move synchronously, so that the notch 109 enters the guide tube 7 to release the bolt.
[0046] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a lifting mechanism is fixedly provided on the side surface of the assembly cabinet 1, an equipment bracket is provided in the operating slot 5, and the equipment bracket is connected to the lifting mechanism, and a screwing mechanism corresponding to the bolts in the guide tube 7 is provided on the equipment bracket. The lifting mechanism is used to drive the equipment bracket to move up and down, and to dock the screwing mechanism with the bolts, and then use the screwing mechanism to screw the bolts into the rectifier bridge.
[0047] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, conductive contacts are provided on the elastic sheet 8, and the conductive contacts control the start and stop of the lifting mechanism and the screwing mechanism. When the bolt is supported and centered by the elastic sheet 8, it contacts the energized contacts on each elastic sheet 8 and starts the operation of the lifting mechanism and the screwing mechanism. If the bolt fails to be centered, it cannot contact all the energized contacts. At this time, the lifting mechanism and the screwing mechanism will not start, which can prevent the bolt from being screwed crookedly into the rectifier bridge and causing damage.
[0048] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a limit plate that cooperates with the slope 92 is fixedly connected to the operating groove 5. The bolts that fall into the through groove 91 and are arranged vertically can pass through the lower side of the limit plate, while the bolts that fail to be arranged along the through groove 91 cannot pass through the limit plate.
[0049] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a rubber pad is fixedly provided on the surface of the slope 92. When the bolt falls on the slope 92, the rubber pad can be used to reduce shock to avoid bumping into the thread and affecting subsequent assembly, and can also reduce the noise generated by the collision.
[0050] A method for using a rectifier bridge assembly device for an automotive AC generator comprises the following steps:
[0051] S1. Place the base plate and shell of the rectifier bridge into the assembly groove 4, push the slide 3 into the interior of the assembly cabinet 1, and then place the bolts along the guide tube 7. At this time, the elastic sheet 8 in the guide tube 7 supports the bolts and centers them on the mounting holes on the shell. Then use the lifting mechanism and the screwing mechanism to screw in the bolts.
[0052] S2. Place the bolt on the slope 92 and let it roll into the through slot 91. The head of the bolt cannot enter the through slot 91 and gets stuck. The screw rod then falls into the through slot 91, causing the bolt to hang vertically and move from left to right along the through slot 91. When the bolt reaches the transverse slot 93, the magnetic base 94 draws the bolt into the guide tube 7.
[0053] S3. After the bolt is installed in the guide tube 7, it is clamped by the clamping plate 108. After the slide 3 is pushed into the assembly cabinet 1, the protrusion 106 on the slide 3 squeezes the triangular block 104 and the slide plate 102 to move, and pulls the clamping plate 108 to move synchronously, so that the notch 109 enters the guide tube 7 to release the bolt.
