Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

The copper brush detecting device of this utility model embodiment, as Figure 1-4, including base 1, and fixing it is positioned on base 1 guide rail 2 extended up and down, this guide rail 2 is respectively provided with one along the left and right sides of base 1, working plate 3 it is provided with, for positioning the fixing copper brush needing detection on working plate 3 bottom the front side of base 1.

Being arranged with guide pin bushing 4 on the guide rail 2 of base 1, the fixing horizontally disposed detection plate 5 that connects of this guide pin bushing 4, the position of detection plate 5 is corresponding up and down with working plate 3 phase, and this detection plate 5 is provided with multiple probe and detection head. Move up and down along guide rail 2 under the driving of the detection plate 5 driving device in base 1 so that probe and the copper brush on detection head and working plate or spy point cantact, and then copper brush is detected and judges. Probe and detection head stretch out the lower section being positioned at detection plate 5 respectively, and then make it possible to contact with the sensitive probe on working plate 3 and shell fragment. Detection head is communicated to power supply so that the both positive and negative polarity shell fragment energising of the copper brush being in contact with it.

Detect the downward guide pillar 55 that is connected with of plate 5, and working plate 3 is provided with the corresponding pilot hole 35 for guide pillar 55 traverse.

Preferably, this detection 51 includes positive pole detection head and negative pole detection head, corresponds respectively to the positive and negative electrode shell fragment of copper brush on working plate 3.

And probe 52 is corresponding to the spy point on working plate 3, as shown in Figure 3,4, this working plate 3 includes flat board 31, and the centring ring 32 of the annular on flat board 31, the mating shapes of centring ring 32 and copper brush prevents for copper brush, and centring ring 32 is two rows, often row three, six alignment are arranged altogether. This centring ring 32 is provided with mean for the hole 33 that the LED of copper brush is inserted, it is provided with sensitive probe in this hole 33, the point 34 of visiting of the output of this sensitive probe is positioned at the outside of centring ring 32, and the probe on detection plate 5 contacts with this spy point 34 downwards, and then judges whether copper brush LED is lighted.

Preferably, each sensitive probe includes two and visits point 34, and the spy point 34 of two corresponding centring ring 32 correspondences of two rows is four altogether, is arranged side by side between upper and lower two centring rings 32.Therefore, the centre of this working plate 3 is provided with altogether three groups of spaced spy points 34, and often group visits point 34 is four. Therefore, the probe 52 on this detection plate 5 also for putting 34 corresponding four with this spy. Being respectively and fixedly provided with copper brush on each centring ring 32 on this working plate 3, the both positive and negative polarity shell fragment interval of copper brush sets up, and therefore, the detection head on detection plate 5 is also the multiple of setting corresponding with both positive and negative polarity shell fragment.

When detection, copper brush is positioned on centring ring 32, and its LED is inserted and is positioned at hole 33, the driving of detection plate 5 device driven of top is downwardly against copper brush, and the probe 52 on detection plate 5 contacts with visiting point 34 simultaneously, and detect 51 to contact with the both positive and negative polarity shell fragment of copper brush copper brush is energized, and then the LED on copper brush lights, and then visit the illuminating state information of point 34 output LED, this signal is read by probe 52, probe 52 is communicated to control module, namely can determine whether whether whether LED is lit problematic. And, the depression distance of detection plate 5 is through setting, pressure can cause a certain amount of deformation of the shell fragment on copper brush down, if under this distance, the deformation of shell fragment is excessive, then can cause that detection head cannot contact with shell fragment, and then copper brush would not be energized, and then LED is without lighting, the information visiting point 34 output judge by controlling module, and then judge that the shell fragment deflection on this copper brush is excessive and copper brush is defective.

This detecting device, it is possible to whether whether qualified and shell fragment the deflection of LED on detection copper brush is qualified, and can pass through the multiple copper brush of shirtsleeve operation one-time detection, and detection efficiency is high, detection accurately, improves the qualification rate of the yield of copper brush.

Although preferred embodiment of the present utility model described in detail above, it is to be clearly understood that for a person skilled in the art, this utility model can have various modifications and variations. All make within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
