The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Embodiment one:
referring to fig. 1 to 11, there is shown a fault detection device applied to an access card. Wherein, the above-mentioned fault detection device includes: the device comprises a frame 1, a conveyor belt 2, a code reader 3, a code reader detection part 5, an entrance guard card pushing part 4 and a pushing detection part 6. Wherein the conveyor belt 2 is arranged on a first side of the frame 1. The code reader 3 is disposed on the first side of the conveyor belt 2, and is used for reading the entrance guard card to be detected conveyed by the conveyor belt 2. The code reader detecting unit 5 is provided on the third side of the code reader 3, and detects the state of the code reader 3. The entrance guard card pushing part 4 is arranged at the fifth side of the code reader detecting part 5 and is used for pushing away the abnormal entrance guard card on the conveyor belt 2. The pushing detection unit 6 is disposed on the sixth side of the entrance guard card pushing unit 4 and connected to the code reader detection unit 5 through a transmission member 7, and after the entrance guard card pushing unit 4 continuously pushes the target number of times, the code reader detection unit 5 detects the code reader 3.
In practice, the first side in this disclosure characterizes the upper side. The second side characterizes the underside. The third side characterizes the left side. The fourth side characterizes the right side. The fifth side characterizes the front side. The sixth side characterizes the rear side.
In practice, the fault detection means in the present application comprise the code reader 3 as a single unit. Specifically, when the plurality of code readers 3 are continuously arranged on the fault detection device, signal interference can be generated among the plurality of code readers 3, so that normal detection of the access card is affected. Meanwhile, the code reader 3 is located on the first side (upper side) of the conveyor belt 2, and only a single code reader 3 is arranged, so that all access cards conveyed by the conveyor belt 2 can be detected one by one.
In practice, the target number may be 3. Namely, after the entrance guard card pushing part 4 is pushed 3 times continuously, the code reader 3 is detected by the code reader detecting part 5. Specifically, the product qualification rate of the access card is often a certain value, for example, 95%, so when the access card pushing unit 4 continuously pushes the target number of times, it can be understood as a non-access card quality cause, and therefore, the code reader 3 needs to be detected by the code reader detecting unit 5. For example, when the code reader 3 is detected by the code reader detecting unit 5, the operation of the conveyor belt 2 is stopped first, then the code reader detecting unit 5 pushes the access card to the bottom of the code reader 3, and verifies whether the code reader 3 works abnormally, and if the code reader 3 works abnormally, reminds a worker to perform fault location and maintenance on the code reader 3. If the code reader 3 is not abnormal, the conveyor belt 2 is controlled to continue to operate.
The entrance guard card pushing part 4 includes: mounting plate 41, first cylinder 42 and push plate 43, wherein: the mounting plate 41 is provided on the third side of the frame 1. The first cylinder 42 is fixed to the third side of the mounting plate 41. The push plate 43 is connected to the fourth side end of the first cylinder 42. When the code reader 3 detects that the access card is abnormal (for example, the access card cannot be read), the first air cylinder 42 pushes the push plate 43 to move when the access card moves to the front of the access card pushing component 4, so that the access card is pushed into the collecting frame, and separation of the abnormal access card and the non-abnormal access card is achieved.
The push detection part 6 includes: first guide bar 61 and second guide bar 62, a plurality of recesses that are slope distribution have been seted up to above-mentioned first guide bar 61 sixth side, wherein: the first guide bar 61 and the second guide bar 62 are symmetrically disposed on the third side of the mounting plate 41. Wherein the first guide bar 61 and the second guide bar 62 are slidably connected to the mounting plate 41. The first guide bar 61 is connected to the mounting plate 41 via a turning wheel 63.
