Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing and relates to testing devices, specifically a circuit board soldering testing device. Background Technology

[0002] A PCB fabrication machine is a high-tech piece of equipment that combines electromechanical, software, and hardware technologies. It is mainly used for the rapid production of printed circuit boards (PCBs). It uses a computer program to control a physical engraving process, milling redundant copper foil onto a copper-clad board to form customized circuits. It is suitable for PCB prototyping in the R&D stage and for small-batch production.

[0003] I found a video of the circuit board production process by searching online. The URL is https: / / www.bilibili.com / video / BV1kZ421N7hN / . As shown in the video, the circuit board needs to go through processes such as material cutting, grinding, drilling positioning holes, drilling, polishing, washing, copper plating, dry film coating, pattern transfer, developing, zinc plating, etching, AOI inspection, solder mask, and screen printing before it can be manufactured.

[0004] However, the AOI inspection process mentioned above involves inspecting the circuit boards using AOI equipment. This requires placing each circuit board individually on the scanning table for scanning, which necessitates multiple placements by employees and cannot be done continuously, making it quite cumbersome. Utility Model Content

[0005] This invention provides a circuit board soldering inspection device that can continuously inspect circuit boards.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a circuit board soldering inspection device, including an etching frame and an etching rack fixedly connected to the etching frame, characterized in that a plurality of conveying rods are rotatably connected to the etching frame, a turntable located on one side of the etching rack is rotatably connected to the etching frame, the turntable is provided with two sorting areas, and a scanning rod located above one of the sorting areas is slidably connected to the frame. When the circuit board enters one of the sorting areas, the turntable rotates and the other sorting area is aligned with the etching rack.

[0007] A further preferred technical solution of this utility model is as follows: a groove is provided on the bottom surface of both sorting areas, and a sensor connected to the turntable and the scanning rod is fixedly connected in the groove. When the circuit board enters one of the sorting areas, the sensor senses and sends a command to the scanning rod and the turntable, and the turntable rotates and the scanning rod slides.

[0008] A further preferred embodiment of this utility model is as follows: the etching frame is fixedly connected to two guide plates between the etching rack and the turntable, and the distance between the two guide plates gradually increases from the end closer to the turntable to the end farther away from the turntable.

[0009] A further preferred embodiment of this invention is that the bottom surface of the turntable and the highest point of the conveying rod are on the same horizontal plane.

[0010] A further preferred embodiment of this utility model is as follows: a motor is fixedly connected to the bottom surface of the etching frame, and the output end of the motor is fixedly connected to the turntable.

[0011] A further preferred embodiment of this utility model is as follows: the turntable is fixedly connected to a protective plate, and the protective plate has an opening to facilitate the entry of the circuit board into the sorting area.

[0012] A further preferred embodiment of this utility model is as follows: an indicator light connected to the scanning rod is fixedly connected to the top surface of the scanning rod. The indicator light is green and red. When the circuit board is compliant, the indicator light is green, and when the circuit board is non-compliant, the indicator light is red.

[0013] A further preferred embodiment of this utility model is that an elastic pad is provided on the inner wall of the guide plate.

[0014] Compared with the prior art, this utility model includes an etching frame and an etching rack. Several conveying rods are rotatably connected to the etching frame, and a turntable located on one side of the etching rack is rotatably connected to the etching frame. The turntable has two sorting areas, and a scanning rod is slidably connected to the frame. Therefore, when inspecting circuit boards, the conveying rods rotate to transport the etched circuit boards to one of the sorting areas. At this time, the turntable rotates, causing the sorting area containing the circuit boards to rotate under the scanning rod. The scanning rod then scans the circuit boards in the sorting area for inspection. Simultaneously, circuit boards to be inspected enter the other controlled sorting area. After the inspection is completed, the turntable rotates to rotate the next sorting area to the scanning rod for inspection. This design allows circuit board inspection to be performed continuously, making the inspection more convenient and faster. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] like Figures 1-4 As shown, the circuit board soldering inspection device includes an etching frame 1 and an etching rack 2 fixedly connected to the etching frame 1. Several conveying rods 3 are rotatably connected to the etching frame 1. A turntable 4 located on one side of the etching rack 2 is rotatably connected to the etching frame 1. The turntable 4 is provided with two sorting areas 11. A scanning rod 7 located above one of the sorting areas 11 is slidably connected to the frame. When the circuit board enters one of the sorting areas 11, the turntable 4 rotates and the other sorting area 11 is aligned with the etching rack 2.

[0021] like Figures 1-4 As shown, when processing the circuit board, the circuit board is placed on the conveyor rod 3. At this time, the conveyor rod 3 rotates, and the circuit board is sent to the etching rack 2 for etching. After etching is completed, the conveyor rod 3 takes the circuit board out and transports it to one of the sorting areas 11. Then the turntable 4 rotates, and the circuit board is rotated to the underside of the scanning rod 7. The scanning rod 7 slides to scan and image the circuit board and compares the image with the correct version of the circuit board image, thereby performing quality inspection on the circuit board. At the same time, while the scanning rod 7 is performing inspection, a new circuit board enters into another sorting area 11. When the previous circuit board is inspected, the turntable 4 rotates again, thereby rotating the next circuit board to the scanning rod 7 for scanning and inspection. like Figures 1-4 As shown, the above describes the usage process of the testing device. The turntable 4 continuously transports the circuit board, enabling the scanning rod 7 to continuously scan and test the circuit board, thereby effectively saving testing time and improving testing efficiency.

[0022] like Figures 1-4As shown, a motor 12 is fixedly connected to the bottom surface of the etching frame 1. The output end of the motor 12 is fixedly connected to the turntable 4. The motor 12 drives the turntable 4 to rotate.

[0023] like Figures 1-4 As shown, the bottom surface of the turntable 4 and the highest point of the conveyor rod 3 are at the same level, so that the circuit board can smoothly enter the sorting area 11 and avoid misalignment of the circuit board and the sorting area 11 due to the height difference.

[0024] like Figures 1-4 As shown, each of the two sorting areas 11 has a groove 10 on its bottom surface. A sensor 6 connected to the turntable 4 and the scanning rod 7 is fixedly connected in the groove 10. When the circuit board enters one of the sorting areas 11, the sensor 6 senses and sends a command to the scanning rod 7 and the turntable 4. The turntable 4 rotates and the scanning rod 7 slides.

[0025] like Figures 1-4 As shown, when the circuit board enters the sorting area 11, the sensor 6 of the sorting area 11 senses the entry of the circuit board and starts the turntable 4. At this time, the turntable 4 rotates, rotating the sorting area 11 with the circuit board to below the scanning bar 7. At the same time, the sensor 6 sends a command to the turntable 4 and also sends a command to the scanning bar 7, so that the scanning bar 7 can start before the sorting area 11 containing the circuit board rotates to below the scanning bar 7, and scan the circuit board in the sorting area 11 after the sorting area 11 arrives, thereby completing the video recording detection. like Figures 1-4 As shown, when the sorting area 11 containing the circuit board is located below the scanning bar 7, the other empty sorting area 11 faces the conveyor bar 3, which facilitates the entry of new circuit boards into the empty sorting area 11. After the previous circuit board is inspected, the turntable 4 rotates again, allowing the circuit boards in the next sorting area 11 to enter below the scanning bar 7. This allows the quality inspection of the circuit boards to be carried out continuously, thereby effectively saving inspection time and improving the speed of inspection.

[0026] like Figures 1-4 As shown, the etching frame 1 is located between the etching frame 2 and the turntable 4 and is fixedly connected to two guide plates 9. The distance between the two guide plates 9 gradually increases from the end closer to the turntable 4 to the end farther away from the turntable 4.

[0027] like Figures 1-4 As shown, by setting the guide plate 9, the circuit board can be guided into the sorting area 11 during the circuit board conveying process, thereby avoiding misalignment between the circuit board and the sorting area 11, which would affect continuous detection, and thus further improving the efficiency and speed of detection.

[0028] like Figures 1-4As shown, the inner wall of the guide plate 9 is provided with an elastic pad, which can protect the circuit board when it comes into contact with the inner wall of the guide plate 9, thereby preventing the guide plate 9 from damaging the circuit board during the process of guiding the circuit board.

[0029] like Figures 1-4 As shown, the turntable 4 is fixedly connected to the protective plate 5. The protective plate 5 has an opening to facilitate the entry of the circuit board into the sorting area 11. When the circuit board enters the sorting area 11, the protective plate 5 can protect the circuit board, thereby preventing the circuit board from separating from the sorting area 11 when the turntable 4 rotates.

[0030] like Figures 1-4 As shown, an indicator light 8 is fixedly connected to the top surface of the scanning rod 7. The indicator light 8 has green and red lights. When the circuit board is compliant, the indicator light 8 lights up green, and the staff can remove the circuit board for storage. When the circuit board is non-compliant, the indicator light 8 lights up red, and the staff needs to remove the non-compliant circuit board for processing. Therefore, it is convenient for the staff to identify the non-compliant circuit board.

[0031] The circuit board soldering inspection device provided by this utility model has been introduced above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
