Description

Technical Field

[0001] This utility model relates to the field of flipping fixture technology, specifically a flipping device for inspecting the appearance of circuit boards. Background Technology

[0002] Circuit boards (PCBs) make circuits miniaturized and more intuitive, playing a crucial role in the mass production of fixed circuits and the optimization of electrical appliance layout. The manufacturing process involves processing the raw materials for PCBs. After the PCBs are formed, they undergo visual inspection to check for defects such as notches, burrs, copper slag, missing components, and misalignment. Inspection often requires flipping the PCB. Existing flipping devices typically use clamping fixtures to flip the PCB. To ensure effective clamping, the fixture presses down on the edges of the PCB's top and bottom surfaces, obscuring the pressed areas and making them undetectable. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-7 This utility model provides a technical solution: a flipping device for circuit board appearance inspection, including an outer frame 1 and an inner frame 2. A rotating component 4 is provided on the outer wall of the right end of the outer frame 1. The rotating end of the rotating component 4 is fixedly connected to the inner frame 2. A supporting component 3 is connected to the bottom of the outer frame 1. A lifting component 5 is provided inside the inner frame 2. The lifting component 5 lifts the circuit board and limits the circuit board, so that when the rotating component 4 drives the inner frame 2 to rotate, the inner frame 2 can drive the circuit board to rotate, thereby flipping the circuit board. The supporting component 5 includes an upper rotating shaft 501, a lower rotating shaft 502, and a second motor 506. Two upper rotating shafts 501 and two lower rotating shafts 502 are provided, and the two upper rotating shafts 501 and lower rotating shafts 502 are symmetrically arranged with respect to the center of the inner frame 2. The upper rotating shafts 501 and lower rotating shafts 502 are rotatably connected to the inner frame 2 via bearings. An upper rotating body 503 is fixedly sleeved on the outer wall of the upper rotating shaft 501, and a lower rotating body 504 is fixedly sleeved on the outer wall of the lower rotating shaft 502. Supporting components 505 are provided on both the upper rotating body 503 and the lower rotating body 504. The ends of the upper rotating shafts 501 and lower rotating shafts 502 are fixedly connected to the output end of the second motor 506. The second motor 506 is fixedly installed on the outer wall of the inner frame 2. When the circuit board is facing upwards, the upper rotating body 503 is connected to... The supporting component 505 is vertical, used to avoid the front of the circuit board, while the supporting component 505 on the lower rotating body 504 is horizontal, used to support the circuit board. During the flipping process, the motor 506 connected to the upper rotating shaft 501 is started first, causing the upper rotating shaft 501 to rotate, which in turn drives the upper rotating body 503 to rotate, so that the supporting component 505 on the upper rotating body 503 presses against the upper surface of the circuit board, thus forming a pressing limit in the upper and lower positions. After the flipping is completed, the motor 506 connected to the lower rotating shaft 502 is started, causing the lower rotating shaft 502 to rotate, which in turn drives the lower rotating body 504 to rotate, so that the supporting component 505 on the lower rotating body 504 is vertical, thus completely exposing the back of the circuit board, achieving the purpose of flipping, and also avoiding the fixture from blocking the circuit board; The lifting assembly 505 includes an extension plate 5051 and a lifting plate 5052. The extension plate 5051 is fixedly connected to the corresponding upper rotating body 503 and lower rotating body 504. The lifting plate 5052 is detached from the extension plate 5051 by screws. The extension plate 5051 is set to install the lifting plate 5052. Different lifting plates 5052 can be replaced to support different circuit boards. The rotating component 4 includes a motor 401, which is fixedly installed on the outer wall of the outer frame 1. A rotating shaft 402 is fixedly installed at the output end of the motor 401. The rotating shaft 402 passes through the outer wall of the outer frame 1 through a bearing. The end of the rotating shaft 402 is fixedly connected to the inner frame 2. The rotating shaft 402 is driven to rotate by the motor 401, thereby driving the inner frame 2 to rotate. The support component 3 includes a base plate 301, and support legs 302 are fixedly installed at the four corners of the top of the base plate 301. The top of the support legs 302 is fixedly connected to the bottom of the outer frame 1. The base plate 301 is set to install the support legs 302, so that the support legs 302 can support the outer frame 1 and separate the outer frame 1 from the base plate 301, so that the inner frame 2 will not collide with the outer frame 1 when it rotates. Anti-detachment protrusions 7 are provided at the connection points of the upper rotating body 503, the lower rotating body 504 and the supporting component 505. The thickness of the anti-detachment protrusions 7 is greater than the thickness of the supporting component 505. The anti-detachment protrusions 7 are provided to separate the circuit board from the upper rotating body 503 and the lower rotating body 504, so as to prevent the circuit board from detaching from the gap between the upper rotating body 503 and the lower rotating body 504. The top of the base plate 301 is provided with mounting holes 9. There are multiple mounting holes 9, which are distributed on the base plate 301. The mounting holes 9 are provided for mounting the base plate 301 on the testing platform. The bottom of the base plate 301 has a groove, and an anti-slip pad 8 is fixedly installed in the groove. The thickness of the anti-slip pad 8 is greater than the depth of the groove. The anti-slip pad 8 is a soft pad. When the base plate 301 is placed, the anti-slip pad 8 at the bottom of the base plate 301 can increase the friction with the placement surface, making the placement more stable. A limiting component 6 is provided between the outer frame 1 and the inner frame 2. The adjusting end of the limiting component 6 rests on the side of the circuit board. The limiting component 6 is provided to hold the circuit board from the side so that the circuit board will not easily shake significantly. The limiting component 6 includes a guide slide rod 601, which slides through the outer walls of the outer frame 1 and the inner frame 2. A guide ring is provided at the point where the guide slide rod 601 passes through the outer frame 1. A side pressure plate 602 is fixedly installed at one end of the guide slide rod 601 that extends into the inner side of the inner frame 2. The side pressure plate 602 presses against the side of the circuit board. A spring 603 is fixedly installed on the outer wall of the side pressure plate 602. The end of the spring 603 is fixedly connected to the inner wall of the inner frame 2. Because the guide slide rod 601 passes through the outer frame 1 and the inner frame 2, the guide slide rod 601 also plays a supporting role for the inner frame 2. The side pressure plate 602 is pushed by the spring 603, pressing the side pressure plate 602 against the side of the circuit board to limit the circuit board. A handle 10 is fixedly installed on one end of the guide slide rod 601 located on the outer side of the outer frame 1. The handle 10 has a thumb groove to facilitate the worker to pull the guide slide rod 601. The side of the side pressure plate 602 that contacts the circuit board is provided with a smooth coating to reduce the friction between the side pressure plate 602 and the circuit board and prevent the edge of the circuit board from being damaged by friction.

[0019] Working principle: In use, first pull the guide slide rod 601 to move the side pressure plate 602 outward from the inner frame 2. Then place the circuit board on the lifting component 505 of the lower rotating body 504. Release the guide slide rod 601, and the spring 603 pushes the side pressure plate 602 to move, so that the side pressure plate 602 presses on the side of the circuit board, limiting the circuit board. The upper surface of the circuit board can then be inspected using the testing equipment. After the upper surface is inspected, the second motor 506 connected to the upper rotating shaft 501 is started, causing the upper rotating shaft 501 to rotate, which in turn drives the upper rotating body 503 to rotate, so that the lifting component 505 on the upper rotating body 503 presses on the upper surface of the circuit board, thus forming a pressing and limiting position in the upper and lower directions. After flipping, the second motor 506 connected to the lower rotating shaft 502 is started, causing the lower rotating shaft 502 to rotate, which in turn drives the lower rotating body 504 to rotate, so that the lifting component 505 on the lower rotating body 504 is vertical, thus completely exposing the back of the circuit board, allowing the back of the circuit board to be inspected.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
