Description

Flying camera and light source test platform of chip mounter

Technical Field

The utility model relates to the field of test auxiliary equipment, in particular to a flying camera and a light source test platform of a chip mounter.

Background

The chip mounter is used as the most core equipment in the whole SMT production line, has high speed, high precision, high automation and high integration, and can rapidly and accurately mount components on a printed circuit board. In order to accurately mount components on a circuit board, a camera is required for recognition. On one hand, the type of the mounted element can be distinguished, so that the mounted element is mounted at a specific position of the circuit board, and on the other hand, whether the element has a certain defect can be judged, and the damaged element is prevented from being mounted. Mature chip mounter generally has three kinds of independent cameras and carries out different recognition function: (1) The flying camera is arranged on the mounting head, and can realize identification in the moving process of the mounting head along with the movement of the mounting head on the XY platform, and is generally used for identifying small-sized elements; (2) The bottom mirror camera is fixed on the base of the chip mounter, and the mounting head can identify the element adsorbed by the mounting head when moving above the bottom mirror camera in the X direction, and is generally used for identifying a larger element; (3) The Mark camera is arranged on the mounting head and is used for identifying marking points on the circuit board after the circuit board is transmitted in and is used for positioning the circuit board.

The flying camera is used as a core component of the visual system of the chip mounter, can realize identification in the moving process of the mounting head, and has important effect on improving the mounting efficiency. The camera is collocated with a light source system, which can provide illumination for the camera. Because the chip mounter needs the numerous kinds of components of dress, in order to guarantee the precision of camera discernment high, then need the light source cooperation of multi-angle to use, such light source system is more complicated, can appear image recognition's problem in flight camera function test stage, for example light and shade inequality, focus unclear etc..

The components such as the flying camera and the light source of the chip mounter need a series of fixed test items by a tester after the assembly is completed, and then the tester can work normally after debugging related problems in the test process, and the current mode is to mount the components such as the flying camera and the light source on the mounting head frame and then carry out related test and debugging work, so that the test and debugging process becomes complicated and wastes time due to the following problems: (1) The flying camera is arranged at the bottom of the mounting head frame, the space where the flying camera and the lens are positioned is narrow, and a tester is difficult to focus and adjust the position of the lens; (2) The light source component is mounted on the mounting head frame after the assembly is completed, if a larger error occurs in the assembly or mounting process, the light source effect is poor, the image shot by the flying camera has uneven brightness and the like, the angle and the position of the light source are required to be finely adjusted by a debugging person, but the light source component is narrow in space, the parts are related, the difficulty of adjusting the light source is higher, and the time consumption is longer; (3) The components such as the flying camera and the light source of the existing chip mounter are fixed on the mounting head frame for testing and debugging, and problems are inevitably found in the testing process, so that debugging personnel are required to frequently disassemble and assemble the components, but the disassembly and assembly are difficult and complicated.

In order to solve the problem that is difficult to avoid, a debugging person needs to adjust the light source and the camera in the test stage, such as focusing the lens, adjusting the angle of the light source, etc., so as to ensure that the light source plays the best effect. However, the components such as the flying camera and the light source of the existing chip mounter are mounted on the mounting head frame, and then relevant testing and debugging work is performed, so that the testing and debugging process becomes complicated and time is wasted due to the problems of small space, large number of parts and the like. Therefore, a novel test platform for the flying camera and the light source is required to be designed, so that test and debugging personnel can conveniently, quickly and efficiently complete the debugging work of the flying camera.
