Abstract
The utility model relates to a mechanical jig, in particular to a jig for detecting a punched hole on a back plate of a light-emitting diode (LED) display device. The jig comprises a bottom plate which is provided with a PIN needle for locating the punched hole, wherein the PIN needle for locating the punched hole is vertically inserted into the bottom plate and extends outside the bottom plate; the bottom plate is provided with an approach switch, and the approach switch is lower than the PIN needle for locating the punched hole; and the approach switch is connected with an external signal input interface of a controller of a punching machine by an inductor connecting hole. The jig saves the manpower, is stable in detection result and unified in standard, and greatly improves the factory yield.
Description
Technical field
The utility model relates to a kind of mechanical tool, particularly a kind ofly whether detects the punching of light-emitting diode display backboard towards saturating detection tool.
Technical background
The backboard of light-emitting diode display is the vitals that liquid crystal panel and circuit board are installed.Light-emitting diode display, the structure more complicated, so as its support and the backboard of positioner on labyrinths such as many fluctuatings as locating hole, screw hole, projection, recessed, chamfering, different shape, trip are also arranged, and these structures all need accurate localization could satisfy the normal mounting of light-emitting diode display.Existing backboard generally all is metal---materials such as aluminium, steel, adopts the technology manufacturing of punching press.Because the progress of technology, existing combination diel can realize the stamped to above-mentioned various CONSTRUCTED SPECIFICATIONs.
In above-mentioned CONSTRUCTED SPECIFICATION, punching (comprising locating hole, screw, through hole etc.) is very crucial structure, and difficulty of processing is relatively large, because need to dash saturating.If there have indivedual punchings not dash to be saturating, that will directly influence the assembling of whole LED display.The manual types that adopt detect more in the existing production, detect the workman light-emitting diode display backboard AutoCAD drawing of the backboard of light-emitting diode display and standard is compared to detect whether small opening is arranged, and whether meet the requirements with heart positions, instrument manual measurement hole such as micrometers.Such detection method labor intensive material resources, and detect the quality instability, detection speed is slow, workman's working strength is big, the product fraction defective is very high.
The utility model content
The purpose of this utility model is the problem that the detection speed that brings for the described manual detection of technical solution background is slow, detect quality unstability, fraction defective height, wasting manpower and material resources, invent the detection tool of a kind of that can directly link with punch press, mechanization, electronic light-emitting diode display backboard punching.
In order to achieve the above object, the technological means of taking is: the detection tool of a kind of light-emitting diode display backboard punching is characterized in that: comprise base plate, base plate is provided with punching location PIN pin, and described punching location PIN pin vertically is inserted on the base plate and stretches out base plate; On the described base plate, below the height of punching location PIN pin, also be provided with near switch, connect the outer signal input interface of the controller of punch press near switch by the inductor connector.
Preferably, punching location PIN arranges a plurality of at the punching position of answering product to be checked.
Further preferred: described also be provided with near switch a plurality of, be distributed in base plate around and middle.
The beneficial effects of the utility model are apparent, can be installed on the modern production line, detect by devices such as the manipulator product of packing into automatically, with near the signal of switch as whether qualified sign, if the defective punch press that directly feeds back to carries out subsequent action and in time handles.Can better save so manually, and testing result is stable, standard is unified, can reduce dispatching from the factory of defective products, improves the yield rate of dispatching from the factory.
Description of drawings
Fig. 1, structure chart of the present utility model.
The specific embodiment
Structure of the present utility model is as shown in Figure 1: comprise base plate 1, base plate 1 is one and holds body to possess sufficient location all around, can hold a product to be detected and unique location.Base plate 1 is provided with the punching location PIN pin 2 of a plurality of corresponding product punching positions, and these punchings location PIN pins 2 can adopt metal to make, and vertically is inserted on the base plate 1 and exceeds base plate 1 certain height, and this highly need be in outside the induction range near switch 3.On the described base plate 1, below the height of punching location PIN pin, also be provided with near switch 3.Also arrange near switch 3 a plurality of, generally around and the centre respectively arrange one, form netted induction covering.A plurality of controller outer signal input interfaces 5 that connect punch press near switch 3 by inductor connector 4.Inductor connector 4 is devices that all are gathered near switching signal.
Detection tool of the present utility model is arranged on the automatic production line, after all punching operations, can arranges manipulator that product to be detected is kept flat and carry out automation on the detection tool of the present utility model and detect.When the punching of product just often, all punching location PIN pins 2 can pass the punching of the correspondence of product, make product can be smoothly and base plate 1 fit, on the base plate 1 all are sensed approach signal near switch 3, as qualified signal, output signal to the outer signal input interface 5 of the controller of punch press by inductor interface 4, machine tool controller is not done bad processing, and automatics such as drift, manipulator can continue the normal flow water conservancy project and do; When product exists not towards saturating " small opening " or punching position deviation, to have indivedual (one or several) corresponding punching location PIN pin 2 can't pass, product can not level be fallen on the base plate 1, namely can't pass the location PIN pin of punching will put product, correspondence position just can not sense approaching of product near switch 3.At this moment, this group exists the signal that approaches to export to the outer signal input interface 5 of punch press controller by inductor interface 4, and the punch press controller thinks that this is to have bad product, can make warning, stop, stops measure such as manipulator carrying, waits pending.
Like this, just realized automatic detection and processing automatically, reduced the probability that defective products dispatches from the factory, improve the product total quality, and the speed that automation detects has been fast, efficient is high, working strength of workers is low.On the other hand, owing to handle through the controller of punch press, can realize counting and bit-error locations statistics easily, for improvement technology, fundamentally improve manufacture level reference data is provided.
