Abstract
The utility model discloses an encoding block, which comprises a long-strip-shaped block body, and is characterized in that the block body is provided with a plurality of through threaded holes at equidistance along the length direction thereof, and screws are detachably arranged in the threaded holes. The encoding block adopts the screws to adjust positions of the holes, so as to realize simple encoding function, and the encoding block is used in cooperation with a photoelectric sensor, so to achieve the purpose of input signals to a PLC. Each set encoding block is a specific signal input device. According to the encoding block, the process of inputting signals through repeated adjustment of a switch is avoided, the efficiency is improved, and the possibility of error is decreased. The encoding block has the advantages of low cost, convenient application, high efficiency and the like.
Description
Technical field
The utility model relates to a kind of encoding block, especially with photoelectric sensor, matches to the encoding block of PLC signal.
Background technology
When carrying out electric test, often need to use the PLC Programmable Logic Controller.When the product of the multiple different size of test, need to, to signal of PLC, remind the test program corresponding to type of PLC switching product.This number of signals is few, but input is frequent, usually adopts at present switch to the PLC input signal, and its cost is relatively high, in the process of repeatedly adjusting, easily input error occurs and efficiency is low.Give how efficiently, quickly the PLC input signal, and cost minimum be present problem demanding prompt solution.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of cost low, the convenient encoding block that uses.
The technical solution of the utility model is to provide a kind of encoding block, and the block that it comprises strip is characterized in that:, along the equidistant screwed hole that is provided with several perforations of its length direction, removably be provided with screw in described screwed hole on described block.
Preferably, be provided with eight described screwed holes on described block, just in time be suitable for the binary signal coding.
Preferably, the two ends of described block are provided with groove, and described groove all starts along perpendicular to the other end of described block length direction to described block, extending from the same end of described block.
Preferably, the diameter of described screwed hole is 8mm, can reduce volume, reduce costs.
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 the purpose of this utility model.
Encoding block of the present utility model utilizes screw to come the position of adjustment hole, thereby realizes encoding function simply, and photoelectric sensor is used in conjunction with, to realize the purpose to the PLC input signal.Each encoding block that sets is exactly a specific signal input apparatus.It has avoided the process of by-pass cock input signal repeatedly, the possibility of makeing mistakes that improved Efficiency Decreasing.It has, and cost is low, easy to use, the efficiency advantages of higher.
Description of drawings
Fig. 1 is the structural representation of a kind of encoding block of the utility model most preferred embodiment.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of encoding block of the present utility model comprises the block 10 of being made by iron plate or aluminium alloy,, along the equidistant screwed hole 12 that is provided with 8 perforations of its length direction, removably is provided with screw (not shown) in screwed hole 12 on block 10.The two ends of block 10 are provided with groove 14, and groove 14 all starts along perpendicular to the other end of block 10 length directions to block 10, extending from the same end of block 10.
During use, at first first, according to the signal of input, in binary mode, on some screw hole, screw is set, the screw hole that is provided with screw represents 0, the binary coding that represents one 8 of the common compositions of 1,8 screw hole that does not arrange.Then, by the screw that passes groove 14, encoding block is fixed on cylinder (not shown) or 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, input into PLC(not shown), reach the purpose to the PLC input signal.The encoding block that several set like this, the product that can solve a plurality of different models is inputted the purpose of type information to PLC before test.
Above embodiment is only the utility model a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
