Detailed description of the invention

Fig. 1 is the main view of the foam tool for detecting height of the utility model；

Fig. 2 is the top view of the foam tool for detecting height of the utility model；

Fig. 3 is the circuit diagram of the foam tool for detecting height of the utility model.

It is as shown in the figure: 10- support base, 11- recessing groove, 20- measurement plate, 21- groove, 30- conductive column, 31- conductive rod, 40- power supply, 50- indicator light.

Specific embodiment

To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this The specific embodiment of utility model is described in detail.It should be noted that the utility model attached drawing is all made of simplified form And non-accurate ratio is used, only to convenient, lucidly aid illustration the utility model embodiment purpose.

As shown in Figure 1 to Figure 3, the utility model provides a kind of foam tool for detecting height, comprising: support base 10, setting Measurement plate 20, conductive column 30, power supply 40 and indicator light 50 on the support base 10.

The top of the measurement plate 20 offers height groove 21 identical with the calibrated altitude of foam to be measured, measurement When, foam to be measured is placed in groove 21 by artificial or machine.Since foam to be measured is located on backing film, therefore measure When backing film lie in the upper surface of measurement plate 20, foam is located in groove 21.If the height of foam complies with standard, steep Bottom surface contact of the bottom of cotton just with groove 21, if the height of foam is lesser, the bottom of foam and groove There are a certain distance for 21 bottom surface.It should be noted that the compressibility due to foam is preferable, if foam height is opposite If calibrated altitude only more (such as within 5%), it can be overcome by way of compression, and since foam is by machine Uniformly completing the process, it is generally also not in height phenomenon mutually far short of what is expected that height error is influenced by mechanical equipment, Therefore, the foam tool for detecting height of the utility model can the height to foam effectively detected.

Please emphasis referring to Fig. 3, the conductive column 30 is arranged in the measurement plate 20 and top and the surface of groove 21 are neat It is flat, so as to be contacted with foam.The conductive column 30, which is provided with multiple groups, to carry out height detection to multiple foams simultaneously. Every group of conductive column 30 includes the conductive rod 31 of two mutually insulateds, and one of conductive rod 31 is connected to the cathode of power supply 40, Another conductive rod 31 is connected to the anode of the power supply 40 by the indicator light 50, if foam and 30 surface of conductive column It contacts, there are conducting particles on foam, and then connect two conductive rods 31 of mutually insulated, electric power loop closure, indicator light 50 It lights.Therefore, whether foam height is up to standard directly can light judgement by indicator light, easy to operate.

Preferably, the conductive rod 31 would generally use the higher copper rod of conductivity, and section of the conductive column 30 Face shape is consistent with the bottom shape of foam to be measured.Specifically, the shape of foam is mostly blocky or cylindric, therefore described is led The section of electric column 30 corresponds to rectangle or circle, correspondingly, the cross sectional shape of the conductive rod 31 is the section of conductive column 30 The half of shape, i.e. rectangle or semicircle so may insure coming into full contact with for foam and 31 surface of conductive rod, it is ensured that conductive Effect.

Further, it is also affixed by glue and the measurement plate 20 after the conductive column 30 passes through the measurement plate 20.

Please emphasis referring to Figures 1 and 2, the arrangement mode of the conductive column 30 is consistent with the arrangement mode of foam to be measured, In other words, the line-spacing of the conductive column 30 and column away from the line-spacing with foam and are arranged away from consistent, as long as the two is aligned in this way, Height detection, high production efficiency can be carried out to multiple groups foam.

Preferably, the measurement plate 20 is made of acrylic board, and the upper surface of acrylic board is coated with wear-resisting Layer, it can be ensured that the measurement accuracy of jig after prolonged use, and effectively extend the service life of jig.

Preferably, being connected between the support base 10 and the measurement plate 20 by fastener.It is easy for installation, structure letter It is single.

With continued reference to Fig. 1 to Fig. 3, recessing groove 11 corresponding with the conductive column 30 is offered on the support base 10, by It needs to connect with external power supply in the conductive column 30, needs to draw multiple conducting wires, the recessing groove 11 is used to supply the conducting wire It passes through, the end of the conducting wire is provided with conductive interface.Since each conductive column 30 is parallel with one another, connect with 40 cathode of power supply It connects and only needs an individual cathode interface that can realize, remaining needs the anode interface connecting with positive pole 40, quantity It is more, usually it is integrated as one or pin interface more than 2.

Further, the power supply 40 and indicator light 50 are integrated on a wiring board, are correspondingly arranged on the wiring board There are multiple Wiring ports, the Wiring port is matched with the conductive interface, only need to be by conductive interface grafting when needing to measure On corresponding Wiring port, the electrical connection of the two can be realized.Certainly, the indicator light 50 on wiring board and Wiring port can Multiple groups are set as with difference according to demand, and then height detection can be carried out simultaneously for the foam in multiple measurement plates 20.

When to sum up, using the foam tool for detecting height of the utility model, it is only necessary to foam is placed into groove 21, On the contrary if foam height is up to standard, corresponding indicator light 50 is lighted, then do not work, and height detection mode is simple, convenient for grasping Work and high production efficiency.

Obviously, it is practical new without departing from this can to carry out various modification and variations to utility model by those skilled in the art The spirit and scope of type.If in this way, these modifications and variations of the present invention belong to the utility model claims and its Within the scope of equivalent technologies, then the utility model is also intended to including these modification and variations.
