DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] like Figure 1 、 Figure 2 As shown, a preferred embodiment of the present invention proposes a PCB board photographing device, which mainly includes a machine 1, a product positioning fixture 2, a rotating module 7, a clamping mechanism and three camera modules. The three camera modules will respectively photograph the top, bottom and side of the PCB board, and the product positioning fixture 2 will position the product.

[0033] There is an avoidance hole in the middle of the machine 1, and the rotating module 7 is located in the avoidance hole. A support frame 10 is provided on the machine 1. The two ends of the support frame 10 are horizontally slidably connected to the slide rails on both sides of the avoidance hole. The support frame 10 is driven and connected to the shift module 23 located in the avoidance hole through a connecting piece. The product positioning jig 2 is fixedly installed on the rotating module 7, and the product positioning jig 2 is driven to move horizontally by the shift module 23. Then the rotating module 7 controls the rotation of the product positioning jig 2 to adjust its position and angle.

[0034] refer to Figure 3The rotating module 7 is composed of a servo motor 71, a reducer 72 and a rotating table 73. The rotating table 73 is installed on the support frame 10. The servo motor 71 is connected to the reducer 72, and the reducer 72 is connected to the rotating table 73. The servo motor 71 drives the rotating table 73 to rotate, thereby driving the product positioning fixture 2 to rotate.

[0035] refer to Figure 4 The product positioning fixture 2 consists of a support plate 201 and a product positioning plate 202. The support plate 201 is fixedly mounted on the rotating table 73, and the product positioning plate 202 is fixed to the support plate 201. The product positioning plate 202 is driven to rotate by the rotating table 73. A positioning groove 2021 is formed on the product positioning plate 202 for positioning the PCB circuit board and the various electronic components located at the bottom of the PCB circuit board. The depth of the positioning groove 2021 is limited so that when viewed from the side, part of the side of the PCB circuit board and the entire side of the various electronic components located at the top can be seen. The product positioning plate 202 is provided with four corner positioning blocks. The corner positioning blocks are in the shape of an "L" and can be used to position the four corners of the PCB circuit board.

[0036] like Figure 1 As shown, in order to facilitate the clamping mechanism to clamp the two sides of the PCB circuit board, there are avoidance grooves 2022 on both sides of the product positioning plate 202 that are connected to the positioning groove 2021. The avoidance grooves 2022 expose the two sides of the PCB circuit board so that the clamping mechanism passes through the avoidance grooves 2022 to clamp the two sides of the PCB circuit board.

[0037] The depth of the avoidance groove 2022 is greater than the depth of the positioning groove 2021. At the same time, the avoidance groove 2022 extends a certain distance into the positioning groove 2021, so that the two sides and the bottom part of the PCB circuit board can be exposed. In this way, the clamping mechanism can not only clamp the two sides of the PCB circuit board, but also lift the bottom of the PCB circuit board upward.

[0038] refer to Figure 3 Two light-blocking sheets 12 are installed at the bottom of the support plate 201, and a photoelectric sensor 11 is installed on the support frame 10. The two light-blocking sheets 12 are symmetrically distributed. The photoelectric sensor 1119 cooperates with the light-blocking sheet 1220 to detect the rotation angle of the product positioning fixture 2.

[0039] like Figure 1 As shown, a code scanning component 6 is provided above the product positioning fixture 2. The code scanning component 6 is fixed on a frame (not shown in the figure). Before taking the formal photo, the PCB circuit board needs to be scanned so that the taken photo can be bound to the QR code and retained, which is helpful for traceability.

[0040] refer to Figure 8The code scanning assembly 6 is composed of a universal seat 61, a first adjustment rod 62, a second adjustment rod 63, an adjustment block 64, a fixed block 65 and a code scanning gun 66. The universal seat 61 is generally fixed to the frame, and one end of the first adjustment rod 62 is connected to the universal seat 61. The universal seat 61 can be used to control the first adjustment rod 62 to rotate at any angle. The second adjustment rod 63 is hinged to the other end of the first adjustment rod 62 and is locked and fixed by a knob. The adjustment block 64 is fixed to the end of the second adjustment rod 63. The fixed block 65 has a slide groove, and the adjustment block 64 is slidably connected to the slide groove. The code scanning gun 66 is installed and fixed on the fixed block 65. The position of the code scanning gun 66 can be adjusted by sliding the adjustment block 64 with the fixed block 65. Since the first adjustment rod 62 and the second adjustment rod 63 are both rotatable, the position of the code scanning gun 66 can be adjusted so that the code scanning gun 66 is close to the PCB circuit board.

[0041] Each PCB has a unique QR code. The scanner 66 scans the QR code and then takes photos of each surface of the PCB. The photos are then linked to the QR code for easy inspection. After scanning, the product positioning jig 2 is transferred to the bottom of the top camera module 5.

[0042] like Figure 5 As shown, a truss 13 is provided on the machine 1 to provide support. A connecting plate 1914 is fixedly mounted on the truss 13, and an adjustment seat 15 is fixedly mounted on the connecting plate 1914. A camera fixing plate 16 is mounted on the adjustment seat 15. The top camera module 5 is vertically fixed to the camera fixing plate 16. The adjustment seat 15 allows for fine-tuning of the position of the top camera module 5. A planar light source 17 is provided below the camera fixing plate 16 to provide fill light for the PCB circuit board below.

[0043] A fixing bar 18 is fixedly connected to the planar light source 17, and the fixing bar 18 is connected to the truss 13 through a connecting plate 1914. A through hole is provided in the middle of the planar light source 17 so that the top camera module 5 can take pictures of the PCB circuit board below through the through hole.

[0044] Bottom camera module 9 is located directly below top camera module 5. After capturing the top of the PCB, bottom camera module 9 takes a picture of the bottom of the PCB. Before capturing the picture, the PCB is clamped to the product positioning jig 2 using a clamping mechanism. Simultaneously, rotating module 7 withdraws to make way for bottom camera module 9, allowing it to capture the bottom of the PCB.

[0045] like Figure 2 、 Figure 6 As shown, the clamping mechanism is composed of two clamping components 3, and the two clamping components 3 cooperate to clamp the two sides of the PCB circuit board.

[0046] The clamping assembly 3 consists of a cylinder mount 31, a lifting cylinder 32, a first cylinder fixing plate 33, an adjustment base 15, a second cylinder fixing plate 34, a clamping cylinder 35, and a clamping member 36. The cylinder mount 31 is generally fixed to the machine platform 1, while the lifting cylinder 32 is vertically fixed to the cylinder mount 31. The first cylinder fixing plate 33 is horizontally arranged and connected to the output end of the lifting cylinder 32, and its vertical movement is controlled by the lifting cylinder 32. The adjustment base 15 is fixedly mounted on the first cylinder fixing plate 33, and the second cylinder fixing plate 34 is mounted on the adjustment base 15. The clamping cylinder 35 is horizontally fixed to the second cylinder fixing plate 34. The position of the clamping cylinder 35 can be fine-tuned via the adjustment base 15.

[0047] The clamping member 36 is connected to the output end of the clamping cylinder 35. A groove is provided on one side of the clamping member 36, which limits the side of the PCB and allows the PCB to be lifted upward. The clamping cylinder 35 controls the clamping member 36 to pass through the avoidance groove 2022 on the product positioning plate 202, approach the PCB, and clamp both sides of the PCB. The lifting cylinder 32 then controls the PCB to move upward, away from the product positioning plate 202. The shift module 23 then controls the support frame 10 to move the rotating module 7 and the product positioning fixture 2 together, away from the bottom camera module 9, so that the bottom camera module 9 can capture the bottom of the PCB.

[0048] The structure of the bottom camera module 9 is similar to that of the top camera module 5, and it also has a planar light source 17. After the shooting is completed, the product positioning jig 2 returns to its original position, and the PCB circuit board is re-placed on the product positioning jig 2. Then the PCB circuit board will be transferred to the position of the side camera module 4.

[0049] like Figure 7 As shown, a linear module 8 is mounted on the machine platform 1. A mounting plate 20 is mounted on the linear module 8. An adjustment seat 15 is fixedly mounted on the mounting plate 20. A camera fixing plate 16 is mounted on the adjustment seat 15. The lateral camera module 4 is horizontally fixed to the camera fixing plate 16. The position of the lateral camera module 4 can be fine-tuned via the adjustment seat 15. The linear module 8 can be used to control the horizontal movement of the lateral camera module 4 and adjust its position.

[0050] A light source fixing plate 21 is fixed on one side of the camera fixing plate 16, and a light source assembly 22 is fixedly installed on the light source fixing plate 21. The light source assembly 22 is located on the front side of the side camera module 4. The side camera module 4 can shoot the PCB circuit board through the light source assembly 22.

[0051] During the shooting, the rotation module 7 controls the rotation of the product positioning fixture 2 so that the side camera module 4 can shoot the four sides of the PCB circuit board. All the photos taken will be recorded in the system and bound to the QR code for storage.

[0052] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
