Description

Technical Field

[0001] This utility model relates to the field of re-inspection equipment technology, specifically a desktop circuit board re-inspection device. Background Technology

[0002] Printed circuit boards (PCBs) are key fundamental components of various electronic devices, and their quality plays a decisive role in the overall performance and reliability of these devices. Therefore, rigorous quality inspection is essential during the PCB manufacturing process. Currently, there are various inspection technologies for PCBs, commonly including manual visual inspection, automated optical inspection (AOI), and automated X-ray inspection (AXI).

[0003] Automated Optical Inspection (AOI) technology uses an optical imaging system to acquire images of circuit boards, and then uses image processing algorithms to compare and analyze these images with preset standard images to determine whether the circuit boards have defects. AOI technology overcomes some of the shortcomings of manual visual inspection to a certain extent, possessing high inspection accuracy and efficiency, and can detect various external and some hidden defects. However, AOI equipment also has limitations in practical applications. For example, for some complex multilayer circuit boards, since the inner layers are covered by the outer layers, it is sometimes difficult to fully and accurately obtain the true condition of the inner layers using only optical imaging. Moreover, during the inspection process, misjudgments or omissions may occur due to factors such as lighting conditions, image acquisition angle, and algorithm adaptability, requiring further verification to ensure the accuracy of the inspection results. Given the limitations of the above-mentioned inspection technology, in the actual circuit board production process, it is often necessary to re-inspect the circuit boards after the initial inspection to further improve the accuracy of the inspection results and reduce the risk of defective products being released.

[0004] Re-inspection is generally carried out using re-inspection equipment. However, the camera position of existing re-inspection equipment cannot be flexibly adjusted, making it difficult to adapt to the re-inspection of products of different specifications, which is very inconvenient and reduces the efficiency of re-inspection.

[0005] In view of this, there is an urgent need for a desktop circuit board re-inspection device. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A desktop circuit board re-inspection device includes: a machine base, on which a camera, a carrier board, a height adjustment mechanism, a horizontal adjustment mechanism, a code reader mechanism, and a drive mechanism are provided;

[0009] The drive mechanism is used to drive the carrier plate to move horizontally, so that the products on the carrier plate pass directly under the camera in sequence.

[0010] The height adjustment mechanism is used to adjust the height of the camera;

[0011] The horizontal adjustment mechanism is used to adjust the horizontal position of the camera;

[0012] The barcode reader mechanism is used to read the barcodes of products passing directly below the camera.

[0013] Its further feature is that,

[0014] The height adjustment mechanism includes a slide rail extending vertically, a mounting base slidably disposed on the slide rail, and a locking screw. The camera is disposed on the mounting base, and the locking screw is used to lock the mounting base onto the slide rail.

[0015] The horizontal adjustment mechanism includes a first linear module horizontally mounted on the machine base and a carrier mounted on the first linear module, with the slide rail mounted on the carrier.

[0016] The barcode reader mechanism includes a barcode reader and a first mounting bracket, which is used to mount the barcode reader on a carrier.

[0017] The first mounting bracket includes a first round rod and a first mounting arm. The first round rod is horizontally positioned and mounted on a carrier. The first mounting arm is sleeved on the first round rod, and the barcode reader is mounted on the first mounting arm.

[0018] It also includes a lighting assembly, which includes a ring light and side lights positioned on opposite sides of the ring light, the ring light being positioned directly below the camera.

[0019] The side lights are all rotatably connected to the ring lights.

[0020] It also includes a positioning mechanism, which includes a laser positioning light and a second mounting bracket, the second mounting bracket being used to mount the laser positioning light on a carrier.

[0021] The second mounting bracket includes a second round rod and a second mounting arm. The second round rod is horizontally positioned and mounted on a carrier. The second mounting arm is sleeved on the second round rod, and the laser positioning light is mounted on the second mounting arm.

[0022] The machine includes a horizontal platform and a chassis disposed on one side of the top surface of the horizontal platform. The carrier plate is disposed on the top surface of the horizontal platform, and the camera, height adjustment mechanism, horizontal adjustment mechanism and code reader mechanism are all disposed on one side of the chassis.

[0023] The above-described structure of this utility model can achieve the following beneficial effects:

[0024] During re-inspection, the product to be inspected is placed on the carrier plate. The drive mechanism drives the carrier plate to move horizontally, so that the products on the carrier plate pass under the camera one by one. The camera takes pictures for re-inspection, and the barcode reader reads the barcode of the products passing under the camera. When re-inspecting different products, the height of the camera is adjusted by the height adjustment mechanism, and the horizontal position of the camera is adjusted by the horizontal adjustment mechanism. This completes the adjustment of the camera position, making it suitable for re-inspection of different products and improving the re-inspection efficiency and versatility of the equipment.

[0025] Because the chassis is located on the top surface of the horizontal platform, there are fewer components inside the platform. Compared to devices with the chassis at the bottom, the bottom of this device has a smaller volume, making it easy to place on a table or desktop for re-inspection, which is convenient for operators to operate and observe. Furthermore, since the camera, height adjustment mechanism, level adjustment mechanism, and barcode reader mechanism are all located on one side of the chassis and are all external components, they are easy to replace and adjust, further improving the ease of use and adaptability.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] refer to Figure 1 and Figure 2 The desktop circuit board re-inspection equipment shown includes: a machine base 1, on which a camera 2, a carrier board 3, a height adjustment mechanism 4, a horizontal adjustment mechanism 5, a code reader mechanism 6, and a drive mechanism are installed. During re-inspection, the product to be inspected is placed on the carrier board 3, and the drive mechanism drives the carrier board 3 to move horizontally (directly below the camera 2), so that the products on the carrier board 3 pass directly below the camera 2 in sequence. The camera 2 takes pictures for re-inspection, and the code reader mechanism 6 reads the codes of the products passing directly below the camera 2. When re-inspecting different products, the height of the camera 2 is adjusted by the height adjustment mechanism 4, and the horizontal position of the camera 2 is adjusted by the horizontal adjustment mechanism 5, thereby completing the position adjustment of the camera 2 to adapt to the re-inspection of different products, improving the re-inspection efficiency and versatility of the equipment.

[0036] like Figure 2 As shown, the height adjustment mechanism 4 specifically includes a slide rail 41 extending vertically, a mounting base 42 slidably disposed on the slide rail 41, and a locking screw 43. The camera 2 is disposed on the mounting base 42. The locking screw 43 is used to lock the mounting base 42 onto the slide rail 41. By manually moving the mounting base 42 on the slide rail 41, the position of the mounting base 42 can be adjusted, thereby achieving the adjustment of the height of the camera 2. The locking screw 43 is threadedly connected to the mounting base 42. Tightening the locking screw 43 causes the end of the locking screw 43 to abut against the slide rail 41, thereby locking the mounting base 42 onto the slide rail 41 and completing the fixation of the height of the camera 2.

[0037] like Figure 2 As shown, the horizontal adjustment mechanism 5 specifically includes a first linear module 51 horizontally set on the machine base 1 and a carrier 52 set on the first linear module 51. The slide rail 41 is set on the carrier 52. The driving direction of the first linear module 51 is perpendicular to the movement direction of the carrier plate 3. In this way, the carrier 52 is driven to make linear movement on the horizontal plane by the first linear module 51, thereby achieving the adjustment of the horizontal position of the camera 2.

[0038] like Figure 3 As shown, the barcode reader mechanism 6 is used to read the identification code on the product. Specifically, it includes a barcode reader 61 and a first mounting bracket. The first mounting bracket is used to install the barcode reader 61 on the carrier 52 to complete the installation of the barcode reader 61. The first mounting bracket includes a first round rod 62 and a first mounting arm 63. The first round rod 62 is horizontally set and is set on the carrier 52. The first mounting arm 63 is sleeved on the first round rod 62. The barcode reader 61 is set on the first mounting arm 63. By rotating the first mounting arm 63 on the first round rod 62 or moving it along the axial direction of the first round rod 62, the reading angle and position of the barcode reader 61 can be adjusted to adapt to reading different products.

[0039] like Figure 2 and Figure 4 As shown, it also includes a lighting assembly 7, which includes a ring light 71 and side lights 72 arranged on opposite sides of the ring light 71. The ring light 71 is positioned directly below the camera 2, thus illuminating the product photographed by the camera 2, making the re-inspection results more accurate. Furthermore, the side lights 72 are rotatably connected to the ring light 71, allowing the lighting direction of the two side lights 71 to be adjusted to adapt to different lighting requirements.

[0040] like Figure 5 As shown, in order to locate defects, this device also includes a positioning mechanism 8. The positioning mechanism 8 includes a laser positioning light 81 and a second mounting bracket. The second mounting bracket is used to set the laser positioning light 81 on the carrier 52. The laser positioning light 81 cooperates with the pre-set positioning point on the carrier plate 3 to achieve the positioning effect. The second mounting bracket includes a second round rod 82 and a second mounting arm 83. The second round rod 82 is set horizontally on the carrier 52. The second mounting arm 83 is sleeved on the second round rod 82. The laser positioning light 81 is set on the second mounting arm 83. By rotating the second mounting arm 83 on the second round rod 82 or moving it along the axial direction of the second round rod 82, the laser angle and position of the laser positioning light 81 can be adjusted to adapt to different positioning requirements.

[0041] A further optimization is that the drive mechanism can adopt a second linear module (not shown in the figure), and the carrier plate 3 is set on the second linear module, so that the installation space required at the bottom of the carrier plate 3 is smaller.

[0042] Further optimization involves the following: the machine 1 includes a horizontal platform and a chassis located on one side of the top surface of the horizontal platform. The carrier plate 3 is located on the top surface of the horizontal platform, while the camera 2, height adjustment mechanism 4, level adjustment mechanism 5, and barcode reader mechanism 6 are all located on one side of the chassis. Since the chassis is located on the top surface of the horizontal platform, there are fewer components inside the horizontal platform. Compared to existing devices that have the chassis located at the bottom, the bottom volume of the carrier plate 3 in this device is smaller, allowing the device to be conveniently placed on a table or desktop for re-inspection, facilitating operation and observation by the operator. Furthermore, since the camera 2, height adjustment mechanism 4, level adjustment mechanism 5, and barcode reader mechanism 6 are all located on one side of the chassis and are all external components, they are easy to replace and adjust, further improving the ease of use and adaptability.

[0043] The working principle of this utility model is as follows: During re-inspection, the product to be inspected is placed on the carrier plate 3. The driving mechanism drives the carrier plate 3 to move horizontally, so that the products on the carrier plate 3 pass directly under the camera 2 in sequence. The camera 2 takes pictures for re-inspection, and the code reader mechanism 6 reads the code of the products passing directly under the camera 2. When re-inspecting different products, the height of the camera 2 is adjusted by the height adjustment mechanism 4, and the horizontal position of the camera 2 is adjusted by the horizontal adjustment mechanism 5, thereby completing the position adjustment of the camera 2 to adapt to the re-inspection of different products, improving the re-inspection efficiency and versatility of the equipment.

[0044] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
