Abstract
An optical device for illuminating a 3D solder paste thickness checking machine comprises a plurality of red LED lamps, a plurality of white LED lamps, LED lamp panels, a plurality of aluminum profile shells, light evening plates and a light source fixing plate. The light source fixing plate is of a polygonal annular structure and comprises a bottom and lateral sides, wherein the included angle between the bottom of each lateral side is 150 degrees. Each aluminum profile shell is a rectangular groove, slide grooves are formed in the middle and the opening edges of the groove, the corresponding LED lamp panel is mounted in the slide groove in the middle, the corresponding LED lamp is mounted on the LED lamp panel, and the corresponding light evening plate is mounted in the slide grooves in the opening edges of the aluminum profile shell. The white LED lamps and the white LED lamps are alternately mounted in the aluminum profile shells fixed on the lateral sides of the light source fixing plate. By the optical device, the problem of uneven illuminating strength during operation of the 3D solder paste thickness checking machine is solved.
Description
Technical field
This device relates to a kind of Optical devices, especially a kind of Optical devices for the illumination of 3D tin cream thickness inspection machine.
Background technology
Surface erection unit is used to, and is directly welded on printed circuit board (PCB) (hereinafter referred to as pcb board) automatically fixing electronic device, as: integrated component, resistance, capacitor.Do not make the welding lead of intending being fixed on pcb board separate, and make those electronic devices there is electrode, for direct welding.The advantage of this method is, because without forming separated hole, each electronic devices and components being fixed on pcb board, has reduced the size of each electronic device, improves significantly the speed of assembling and making, and reduces the size of whole product.
During with surperficial erection unit welding, because each electronic device is very little, can not each electronic device be arranged on pcb board exactly; Or the amount of solder flux is too large, so that may make the electromotive force of two adjacent electrodes too high, thereby can cause the problems such as short circuit.Therefore,, after completing each device of welding, check their installation and welding situation, to reduce the defect rate of product.
In order to check installation and the welding situation of the device of surperficial erection unit welding, have a large amount of work to check by hand, but this is difficult to realize the manual inspection of homogeneous.
So, while welding the installation of device and welding situation on checking pcb board, be by with camera illumination with take pictures, and with the photo of gained, differentiate installation and the welding situation of each device, carry out automatic inspection process.
Summary of the invention
The invention provides a kind of Optical devices for the illumination of 3D tin cream thickness inspection machine, solved the inhomogeneous problem of 3D tin cream thickness inspection machine illumination intensity in service.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Optical device for the illumination of 3D tin cream thickness inspection machine, comprising: red LED lamp, white led lamps, LED lamp plate, aluminium section bar shell, even tabula rasa and light source fixed head; Described light source fixed head is polygon loop configuration, comprising: bottom surface and side, and described bottom surface and side are 150 degree; Described aluminium section bar shell is rectangular recess, at centre and the edge of opening of groove, is provided with chute, and LED lamp plate is arranged in the chute in the middle of aluminium section bar outer casing groove, and LED lamp is arranged on LED lamp plate, and even tabula rasa is arranged in the chute at aluminium section bar shell aperture edge; Aluminium section bar shell is fixed on the side of light source fixed head; Described red LED lamp, white led lamps and lamp aluminium section bar shell are a plurality of, and red LED lamp and white led lamps are alternately arranged in the aluminium section bar shell on the side that is fixed on light source fixed head;
Described light source fixed head is steel plate sheet metal component.
Beneficial effect of the present invention is: adopt LED solid state light emitter to detect required Uniform Illumination light for 3D tin cream thickness inspection machine provides, avoid the detection error causing because of the even generation shade of uneven illumination, improved 3D tin cream thickness inspection machine precision and detection efficiency.
Accompanying drawing explanation
The present invention has accompanying drawing 2 width.
Fig. 1 is structural representation of the present invention;
Fig. 2 is aluminium section bar shell mechanism schematic diagram.
Sequence number explanation in figure: 1, red LED lamp, 2, white led lamps, 3, light source fixed head, 4, aluminium section bar shell.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Optical device for the illumination of 3D tin cream thickness inspection machine, comprising: red LED lamp 1, white led lamps 2, LED lamp plate (not marking in figure), aluminium section bar shell 4, even tabula rasa (not marking in figure) and light source fixed head 3; Described light source fixed head 3 is polygon loop configuration, comprising: bottom surface and side, and described bottom surface and side are 150 degree; Described aluminium section bar shell 4 is rectangular recess, centre and edge of opening at groove are provided with chute, LED lamp plate is arranged in the chute in the middle of aluminium section bar shell 4 grooves, and LED lamp is arranged on LED lamp plate, and even tabula rasa is arranged in the chute of aluminium section bar shell 4 edge of opening; Aluminium section bar shell 4 is fixed on the side of light source fixed head 3; Described red LED lamp 1, white led lamps 2 and lamp aluminium section bar shell 4 are a plurality of, and red LED lamp 1 and white led lamps 2 are alternately arranged in the aluminium section bar shell 4 on the side that is fixed on light source fixed head 3, and described light source fixed head 3 is steel plate sheet metal component.
When 3D tin cream thickness inspection machine is worked, first trigger white led lamps 2, the video acquisition module of 3D tin cream thickness inspection machine is identified MARK point, whether the locality that judges pcb board placement is correct, if correct, start red LED lamp 1, whole pcb board taken pictures, the present invention has utilized the difference of white led lamps optical wavelength and red LED lamp optical wavelength to carry out object identification to pcb board, and the light that white led lamps 2 and red LED lamp 1 are irradiated is out without shadow light, this lighting system has been avoided the shade producing because polishing is inhomogeneous, thereby have influence on the precision of detection.
