Keyboard LED detection device and detection methodTechnical field
The present invention relates to a kind of automatic detection device for keyboard, especially a kind of keyboard LED detection device and detection method.
Background technique
Keycap on existing keyboard with LED light is usually manually visually to judge whether the brightness of LED light and position are quasi-Really, but such decision procedure usually can not accurately judge the brightness value, chromatic value and offset of LED light, therefore judgeAs a result precision is lower, and cost of labor is higher.
Keyboard LED backlight plate includes flexible plate body, and flexible plate body is equipped with LED light and golden finger, the pin and gold of LED lightFinger is electrically connected, usually when brightness value, chromatic value and the offset to keyboard LED detect, in order to guarantee productShipment quality need to carry out LED light function to light test.Traditional lighting test method is usually the artificial touching for using multimeterThe leg or golden finger of head test LED light, this test method, which is easy to generate the leg or golden finger of LED light, scratches pressureTrace is easily damaged the leg or golden finger of LED light, causes product that can not continue to use after test.
Summary of the invention
Goal of the invention: the present invention provides a kind of keyboard LED detection device and detection method, keyboard LED detection devicesCan brightness, coloration and offset etc. to the LED light on keyboard accurately detected and compared, participated in without artificial,And it being capable of batch detection；It can guarantee product not to be caused to damage in detection process.
Technical solution: a kind of keyboard LED detection device, including stop cylinder, pressing plate probe, camera, barcode scanning gun, support plate andJack positioning mechanism；Wherein, support plate is installed on conveyer belt, and support plate side is equipped with notch, and stop cylinder is located at support plate side and lacksAt mouthful and it can move up and down；The circuit board connecting with LED light on keyboard is provided on support plate, pressing plate probe can be with circuit after pushingPlate conducting is to light the LED light on keyboard；Camera is for shooting the LED light on keyboard and carrying out brightness, coloration and offsetDetermine；The barcode scanning gun is used to scan the bar code on keyboard with label detection keyboard.Location hole is offered on support plate, jacking is fixedIt is provided with positioning protrusion in the mechanism of position, when stop cylinder moves up, and support plate is stopped to travel forward, jacking positioning mechanism is upwardMovement is until positioning protrusion passes through location hole and positions support plate.
Support plate location hole is protruded into fix support plate in order to facilitate positioning protrusion, and positioning protrusion upper end is cone.IntoOne step, positioning protrusion is replaced or dismantles for convenience, positioning protrusion two sides are provided with vertical plane, are clamped with convenient wrench etc.Or it screws.
In order to prevent after positioning protrusion protrudes into location hole, location hole side wall is scratched, positioning hole is provided circumferentially about to be hadGuide sleeve, guide sleeve material are rubber.
The invention also discloses the method using above-mentioned keyboard LED detection device detection LED lamp for keyboard, specifically include asLower step:
1) support plate is transmitted by conveyer belt and is flowed into inside equipment；
2) the keyboard number on barcode scanning gun scanning support plate；
3) stop cylinder rises until gear is in support plate indentation, there；Positioning mechanism is jacked to rise until positioning protrusion passes through positioningHole positions support plate；
4) pressing plate probe pushes until contacting with support plate, and be connected to light on keyboard with the circuit board on support plateLED light；
5) state after camera shooting the lighting of LED lamp for keyboard, and carry out the comparison of brightness value, chromatic value and offsetAnd judgement；
6) decline of jacking positioning mechanism is until positioning protrusion deviates from location hole, and stop cylinder decline is until concede support plate outflowHighly, support plate flows out.
The utility model has the advantages that keyboard LED detection device disclosed by the invention can automatic batch detection LED lamp for keyboard, detectedIt can guarantee not damage product in journey, and product orientation is accurate, therefore the corresponding circuit of LED light on its support plate and probe canAccurately connection conducting one by one；Product testing process is participated in without artificial, and all measurement data can quantify.

Specific embodiment
As shown in Figure 1, a kind of keyboard LED detection device, including stop cylinder 1, pressing plate probe 2, camera 3, barcode scanning gun 4,Support plate 5, jacking positioning mechanism 6；Support plate 5 is installed on conveyer belt, and 5 side of support plate is equipped with notch 51, and stop cylinder 1 is located at support plateAt 5 side notches 51 and it can move up and down；The circuit board 52 connecting with LED light on keyboard, pressing plate probe 2 are provided on support plate 51It can be connected to light the LED light on keyboard with circuit board 52 after pushing；Camera 3 is used to shoot LED light and the progress on keyboardBrightness, coloration and offset determine；Barcode scanning gun 4 is used to scan the bar code on keyboard with the number of label detection keyboard.
Wherein, location hole 53 is offered on support plate 5, is jacked and is provided with positioning protrusion 61 on positioning mechanism 6, works as stop cylinder1 moves up and stops support plate 5 when travelling forward, and jacking positioning mechanism 6 moves upwards until positioning protrusion 61 passes through location hole 53Support plate 5 is positioned.Positioning protrusion 61 scratches the location hole 53 on support plate 5 in order to prevent, is provided with and leads on 53 inner periphery of location holeSet 531,531 material of guide sleeve are rubber.
Circuit board on support plate 5 uses FPC, that is, flexible circuit board, and the route and LED light on flexible circuit board correspond,Pressing plate probe 2, which is pushed, contacts lightening LED lamp with flexible circuit board.
For the ease of protruding into location hole 51,61 upper end of positioning protrusion is cone, as shown in Fig. 2, its lower end is cylinderShape, this cylindrical diameter are identical as 531 annular diameters size of guide sleeve in location hole 53.61 two sides of positioning protrusion are provided with verticallyFace, to facilitate tool when installation or disassembly that can find impetus.
A method of LED lamp for keyboard being detected using above-mentioned keyboard LED detection device, is specifically comprised the following steps:
1) support plate 5 is transmitted by conveyer belt and is flowed into inside equipment；
2) barcode scanning gun 4 scans the keyboard number on support plate 5；
3) stop cylinder 1 rises until gear is at 5 notch 51 of support plate, and blocking support plate travels forward, 5 stop motion of support plate；Jacking positioning mechanism 6 rises until positioning protrusion 61 passes through location hole 53 and positions support plate 5；
4) pressing plate probe 2 pushes until contacting with support plate 5, and be connected to light keyboard with the circuit board 52 on support plate 5On LED light；
5) camera 3 shoots the state after the lighting of LED lamp for keyboard, and carries out the ratio of brightness value, chromatic value and offsetTo and determine；
6) decline of jacking positioning mechanism 6 is until positioning protrusion 61 deviates from location hole 53, and the decline of stop cylinder 1 is until concede loadThe outflow height of plate 5, support plate 5 flow out.
