Description

Technical Field

[0001] This utility model relates to the field of AOI detection technology, specifically to an adjustable AOI detection auxiliary device. Background Technology

[0002] AOI stands for Automated Optical Inspection, a device that uses optical principles to detect common defects encountered in soldering production. AOI is a relatively new testing technology, but its development has been rapid, with many manufacturers launching AOI testing equipment. During automatic inspection, the machine automatically scans the PCB using a camera, acquires images, compares the tested solder joints with acceptable parameters in a database, processes the images, identifies defects on the PCB, and displays / marks these defects on a monitor or with automatic indicators for repair personnel to fix.

[0003] Currently, AOI and AOI testing are used in many fields. When performing AOI testing on a circuit board, the staff needs to place the circuit board in the AOI testing equipment and then perform optical scanning. However, the inspection of the circuit board usually involves two sides of the circuit board. After the equipment has inspected one side of the circuit board, the staff still needs to manually flip it over, which reduces work efficiency and increases the workload of the staff.

[0018] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 As shown, an adjustable AOI detection auxiliary device includes a support leg 1, a support frame 2 fixed to the surface of the support leg 1, a housing 3 fixed to one side of the surface of the support frame 2, a rotating mechanism 4 provided in the inner cavity of the housing 3, a first clamping frame 5 provided on the surface of the rotating mechanism 4, a second clamping member 6 used in conjunction with the first clamping frame 5 provided on the other side of the surface of the rotating mechanism 4, a dust suction mechanism 7 provided on one side of the surface of the support leg 1, and a moving mechanism 8 used in conjunction with the dust suction mechanism 7 provided on one side of the surface of the support frame 2.

[0020] When performing AOI testing, this utility model can rotate the circuit board by the first clamping frame 5 and the second clamping member 6 under the action of the rotating mechanism 4, thereby facilitating the AOI testing equipment to perform double-sided AOI testing on the circuit board and improving the practicality of the device. In addition, under the action of the dust suction mechanism 7 and the moving mechanism 8, the surface of the circuit board can be vacuumed to avoid dust on the surface of the circuit board from affecting the AOI testing work.

[0021] The first clamping frame 5 moves towards the second clamping member 6 via a spring or drive motor, thereby achieving the purpose of clamping the circuit board, which will not be elaborated here.

[0022] The rotating mechanism 4 includes a first motor 41 fixed to the inner cavity of the outer shell 3. The output shaft of the first motor 41 is fixed with a rotating rod 42. The other end of the rotating rod 42 is fixed with a rotating frame 43. The other end of the rotating frame 43 is fixed with a rotating limiting member 44. The other side of the rotating limiting member 44 rotates within the inner cavity of the support frame 2. The first clamping frame 5 slides within the inner cavity of the rotating frame 43. The second clamping member 6 is fixed to one side of the inner cavity of the rotating frame 43. In this embodiment, through the arrangement of the first motor 41, the rotating rod 42, the rotating frame 43, and the rotating limiting member 44, the rotating rod 42 rotates under the action of the first motor 41. Thus, the rotating frame 43 fixed to the surface of the rotating rod 42 can be restricted by the rotating limiting member 44, causing the first clamping frame 5 and the second clamping member 6 to rotate the circuit board.

[0023] The first motor 41 is a servo motor and has a built-in brake device. In this embodiment, this setting improves the accuracy of the first motor 41 when it rotates, and under the action of the brake device, the rotating rod 42 and the rotating frame 43 can be stably stopped at the designated position.

[0024] The dust collection mechanism 7 includes a dust collection box 71 fixed to the surface of the support leg 1. A dust collection pump 72 is connected to the surface of the dust collection box 71. Connecting pipes 73 are connected to both sides of the surface of the dust collection box 71. A connecting hose 74 is connected to the other end of the connecting pipe 73. A dust collection hood 75 is connected to the other end of the connecting hose 74. A dust collection hole 76 is opened on the surface of the dust collection hood 75. In this embodiment, through the arrangement of the dust collection box 71, the dust collection pump 72, the connecting pipe 73, the connecting hose 74, the dust collection hood 75 and the dust collection hole 76, a negative pressure is generated in the dust collection pump 72 under the action of the dust collection box 71. Then, under the action of the connecting pipe 73 and the connecting hose 74, the dust collection hood 75 performs dust collection through the dust collection hole 76.

[0025] The width of the dust hood 75 is smaller than the width of the support frame 2. In this embodiment, this arrangement ensures that when the dust hood 75 is on the surface of the support frame 2, it will not interfere with the circuit boards in the first clamping frame 5 and the second clamping member 6, thereby improving the practicality of the device.

[0026] The moving mechanism 8 includes a housing 81 fixed to one side of the surface of the support frame 2. A second motor 82 is fixed inside the housing 81. A threaded rod 83 is fixed to the output shaft of the second motor 82. The threaded rod 83 engages with the dust collection hood 75. A limit rod 9 is slidably provided at the other end of the dust collection hood 75. Both sides of the limit rod 9 are fixed to the surface of the support frame 2. In this embodiment, through the arrangement of the housing 81, the second motor 82, the threaded rod 83, and the limit rod 9, the threaded rod 83 and the dust collection hood 75 can be engaged under the action of the second motor 82, thereby allowing the dust collection hood 75 to move under the restriction of the limit rod 9, thus changing the working range of the dust collection mechanism 7.

[0027] Working principle: When AOI inspection of a circuit board is required, the operator can fix the circuit board to the surface of the rotating frame 43 using the first clamp 5 and the second clamp 6. The PLC control system can then activate the vacuuming mechanism 7 and the moving mechanism 8. Under the action of the vacuum pump 72, connecting pipe 73, connecting hose 74, and vacuum hood 75, airflow is generated in the vacuum hole 76. Under the action of the second motor 82 and the threaded rod 83, the vacuum hood 75 moves the vacuum hole 76, thereby vacuuming one side of the circuit board. After the vacuuming is completed, the vacuum hood 75 is reset under the control of the PLC. This process can prevent dust on the surface of the circuit board from affecting the AOI inspection.

[0028] Then, under the action of the AOI inspection head, the circuit board can be inspected by AOI. After the AOI inspection of one side is completed, the first motor 41 can cause the rotating rod 42 to drive the rotating frame 43 to flip, so that the other side of the circuit board is exposed in the AOI inspection working area. Then, the vacuuming mechanism 7 and the moving mechanism 8 can be used to vacuum it. After that, the surface of the circuit board can be inspected again by AOI inspection.
