Abstract
The invention discloses a code block which comprises a block body of a long strip shape. The code block is characterized in that a plurality of through threaded holes are formed in the block body in the length direction in an equidistance mode, and screws are detachably arranged inside the threaded holes. According to the code block, the screws are used for adjusting the positions of the threaded holes so that a coding function can be achieved simply, the code block and a photoelectric sensor are matched to be used so as to achieve the purpose that signals are input to a PLC. Each set code block is a specific signal input device. The process that switch input signals are repeatedly adjusted is avoided, efficiency is improved, and the probability of errors is lowered. The code block has the advantages of being low in cost, convenient to use, high in efficiency and the like.
Description
Technical field
The present invention relates to a kind of encoding block, especially match to the encoding block of PLC signal with photoelectric sensor.
Background technology
When carrying out electric test, often need use the PLC Programmable Logic Controller.When the product of the multiple different size of test, need to give signal of PLC, remind PLC to switch the test program of the type correspondence of product.This number of signals is few, but input is frequent, adopts switch to give the PLC input signal at present usually, and its cost is higher relatively, in the process of adjusting repeatedly, easily input error takes place and efficient is low.Give the PLC input signal how efficiently, quickly, and cost minimum be present problem demanding prompt solution.
Summary of the invention
In order to overcome the problems referred to above, the invention provides low, the convenient encoding block that uses of a kind of cost.
Technical scheme of the present invention provides a kind of encoding block, and the block that it comprises strip is characterized in that: the equidistant screwed hole that is provided with several perforations of its length direction of described block upper edge removably is provided with screw in the described screwed hole.
Preferably, described block is provided with eight described screwed holes, just in time is suitable for the binary signal coding.
Preferably, the two ends of described block are provided with groove, and described groove all begins along extending perpendicular to the other end of described block length direction to described block from the same end of described block.
Preferably, the diameter of described screwed hole is 8mm, can reduce volume, reduce cost.
Preferably, the width of described groove is 8.5mm.
Preferably, described block is made by iron plate or aluminium alloy, or and so on common material, as long as any material that is not easy to be out of shape can be realized purpose of the present invention.
Encoding block of the present invention utilizes screw to come the position of adjustment hole, thereby realizes that encoding function and photoelectric sensor are used simply, to realize giving the purpose of PLC input signal.Each encoding block that configures is exactly a specific signal input unit.It has avoided the process of by-pass cock input signal repeatedly, has improved efficient and has reduced the possibility of makeing mistakes.It has, and cost is low, easy to use, the efficient advantages of higher.
Description of drawings
Fig. 1 is the structural representation of a kind of encoding block of most preferred embodiment of the present invention.
Embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of encoding block of the present invention comprises the block of being made by iron plate or aluminium alloy 10, and the equidistant screwed hole 12 that is provided with 8 perforations of its length direction of block 10 upper edges removably is provided with screw (not shown) in the screwed hole 12.The two ends of block 10 are provided with groove 14, and groove 14 all begins along extending perpendicular to the other end of block 10 length directions to block 10 from the same end of block 10.
During use, according to the signal of input, at some screw hole screw is set in binary mode at first earlier, the screw hole that is provided with screw represents 0, not the common binary coding of forming one 8 of 1,8 screw hole of the representative of She Zhiing.Then, by the screw that passes groove 14 encoding block is fixed on cylinder (not shown) or the motor (not shown), it is at the uniform velocity passed through under photoelectric sensor (not shown), thereby read out the binary coding of encoding block, it is not shown that PLC(is advanced in input), reach the purpose to the PLC input signal.The encoding block that several configure like this, the product that can solve a plurality of different models is imported the purpose of type information to PLC before test.
Above embodiment only is the present invention's a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
