The application includes the following advantages.
In the embodiment of the application, the positioning apparatus includes a sensor assembly, a moving member, and a detecting plate. The sensor assembly includes a sensor positioning and detecting assembly and a sensor location recognition assembly. The sensor assembly is mounted on the moving member, and the moving member drives the sensor assembly to move on the detecting plate.

Furthermore, the card issuing machine provided by the application is lower in cost than a stepping motor or a servo motor, and occupies smaller space.
To make the foregoing objectives, features, and advantages of the application more apparent and lucid, the application is further described in detail below with reference to the accompanying drawings and embodiments.
Referring to
Of course, the specific number of the signal sensors 14 in the sensor positioning and detecting assembly 111 and the sensor location recognition assembly 112 may also be set according to actual needs, which is not limited by the embodiments of the application.
The sensor assembly 11 is mounted on the moving member 12, and the moving member 12 drives the sensor assembly 11 to jointly move on the detecting plate 13. The sensor assembly 11 moves on the detecting plate 13, and after the sensor location recognition assembly 112 recognizes that the sensor assembly 11 has reached the designated location, the sensor positioning and detecting assembly 111 positions the sensor assembly 11.
The detecting plate 13 is fixed, and the sensor assembly 11 may be either in contact with or not in contact with the detecting plate 13. For example, supposing a sensor in the sensor assembly needs to capture a signal by way of contact, the sensor assembly 11 may be in contact with the detecting plate 13, or supposing the sensor in the sensor assembly does not need to capture a signal by way of contact, the sensor assembly 11 may be not in contact with the detecting plate 13, which may be set according to actual needs and not limited in the embodiments of the application.
Referring to
The signal sensor includes but is not limited to a bijective optocoupler, or an emission-type optocoupler, or a laser generator, or an ultrasonic wave, or a Hall device, or an inductive coil, etc. The detecting plate includes but is not limited to a silk screen, or a film, or a salient point, or an aperture and so on, which is used for shielding or reflecting light or signals, or for electromagnetic induction, etc.
That is, any apparatus may serve as the signal sensor as long as it can generate a signal that may penetrate through the aperture or be shielded by the detecting plate, which is not limited in the embodiments of the application.
In a preferred embodiment of the application, recognizing, by the sensor location recognition assembly, that the sensor assembly reaches a designated location includes:
separately detecting whether each of the signal sensors in the sensor location recognition assembly is shielded;
recording status information of each of the signal sensors, the status information including being shielded or being not shielded;
calculating out a current location of the sensor assembly according to the status information of each of the signal sensors;
determining whether the current location of the sensor assembly is the designated location; and
determining that the sensor assembly has reached the designated location if it is determined that the current location of the sensor assembly is the designated location.
In a preferred embodiment of the application, the status information of each of the signal sensors is recorded using binary values.
The current location of the sensor assembly is determined by a corresponding binary value.
Specifically, the status information is marked as 0 when the signal sensor is shielded, and the status information is marked as 1 when the signal sensor is not shielded, or the status information is marked as 1 when the signal sensor is shielded, and the status information is marked as 0 when the signal sensor is not shielded, and then the location of the sensor assembly is determined according to the binary value of each of the signal sensors in the sensor location recognition assembly. For example, the sensor location recognition assembly includes eight optocouplers, and the binary values of the eight optocouplers are 0/0/0/0/0/0/1/0, respectively. In this case, the location of an optocoupler plate is a “00000010” layer location. The binary value may also be converted into a decimal value, which is 2, and i.e., “3” layer location when applying to the device. The binary value 00000000 may be converted into a decimal value which is 0, i.e., “1” layer location when applying to the device.
In practical application, when an instruction indicating that the sensor assembly has moved to a designated location is received, the sensor assembly may move toward the designated location. In the movement process of the sensor assembly, status information of the sensor location recognition assembly is continuously recognized. When the status information of the sensor location recognition assembly is consistent with the status information corresponding to the designated location, it may be determined that the sensor assembly has reached the designated location.
In a preferred embodiment of the application, positioning the sensor assembly by the sensor positioning and detecting assembly includes:
determining whether the signals from the signal sensors in the sensor positioning and detecting assembly penetrate through the apertures simultaneously; and
determining that the sensor assembly is positioned successfully if it is determined that the signals from the signal sensors in the sensor positioning and detecting assembly penetrate through the apertures simultaneously; otherwise
the sensor assembly moving on the detecting plate until the signals from the signal sensors in the sensor positioning and detecting assembly penetrate through the apertures simultaneously.
Specifically, after the sensor assembly has reached the designated location, to ensure the sensor assembly may position more accurately, the sensor positioning and detecting assembly needs to position the sensor assembly. Referring to
After the sensor assembly has reached the designated location, if the signals from each of the signal sensors in the sensor positioning and detecting assembly do not penetrate through the apertures simultaneously, the sensor assembly is finely tuned until the signals from each of the signal sensors in the sensor positioning and detecting assembly penetrate through the apertures simultaneously.
The application is specifically described below by way of specific examples.

It is to be noted that for ease of description, the ten signal sensors in
When the sensor assembly moves to the second layer, the ten signal sensors move up simultaneously. First, the No. 1 signal sensor is separated from a light transmission grid square and is shielded, and the No. 2 to No. 10 signal sensors are still in their respective apertures, and the information returned is “1/0, 0/0/0/0/0/0/0”, which is decoded as the sensor assembly being between the first layer and the second layer and near the first layer location at this moment. Referring to
When the sensor assembly moves to the third layer, the ten signal sensors move up simultaneously. First, the No. 2 signal sensor is separated from the aperture and is shielded, the No. 1 signal sensor and the No. 3 to No. 9 signal sensors are still in their respective apertures, the No. 10 signal sensor is shielded, and the information returned is “0/1, 0/0/0/0/0/0/0/1”, which is decoded as the sensor assembly being between the second layer and the third layer and near the second layer location at this moment. Referring to
It is to be noted that the No. 1 to No. 10 signal sensors are numbered for the purpose of illustration, such that the signal sensors are differentiated, and these signal sensors are identical.
In the embodiments of the application, the positioning apparatus includes a sensor assembly, a moving member, and a detecting plate. The sensor assembly includes a sensor positioning and detecting assembly and a sensor location recognition assembly. The sensor assembly is mounted on the moving member, and the moving member drives the sensor assembly to move on the detecting plate. The sensor assembly moves on the detecting plate, the sensor location recognition assembly recognizes that the sensor assembly reaches a designated location, and the sensor assembly is positioned by the sensor positioning and detecting assembly. In this way, the moving member drives the sensor assembly to move together, thereby avoiding the phenomena of step lost and speed reduced, and the location of the sensor assembly can be monitored in real time through the detecting plate. Furthermore, the card issuing machine provided by the application is lower in cost than a stepping motor or a servo motor, and occupies smaller space.
An embodiment of the present invention discloses a card issuing machine, which includes a lateral positioning apparatus and a vertical positioning apparatus. The lateral positioning apparatus and the vertical positioning apparatus employ the positioning apparatus according to the above embodiments. The lateral positioning apparatus is a positioning apparatus formed by rotating the positioning apparatus to the left or right by 90 degrees.
Finally it should be explained that a relational term (such as a first or a second) is merely intended to separate one entity or operation from another entity or operation instead of requiring or hinting any practical relation or sequence exists among these entities or operations. Furthermore, terms such as “comprise”, “include” or other variants thereof are intended to cover a non-exclusive “comprise” so that a process, a method, a merchandise or a terminal device comprising a series of elements not only includes these elements, but also includes other elements not listed explicitly, or also includes inherent elements of the process, the method, the merchandise or the terminal device. In the case of no more restrictions, elements restricted by a sentence “include a” do not exclude the fact that additional identical elements may exist in a process, a method, a merchandise or a terminal device of these elements.
A positioning apparatus and a card issuing machine provided by the application are described in detail above. Principles and implementations of the application are elaborated by using specific examples herein, and the description of the foregoing embodiments is merely intended to assist in understanding the method of the application and the core concept thereof. Also, those of ordinary skill in the art may change, in according with the concept of the application, a concrete implementation and a scope of application. In conclusion, contents of the specification shall be not interpreted as limiting the application.
