Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
By way of example, the system for realizing automatic code pasting comprises a vehicle, a track matched with the vehicle, and a laser reflection plate matched with a laser range finder fixed on the body of the vehicle, wherein the vehicle is started and can run along the track. Then, the distance of the vehicle moving relative to the initial position is measured through the laser range finder and the laser reflection plate, so that the fact that the vehicle reaches the code pasting position is determined.
Preferably, fig. 1 is a system for implementing automatic coding according to an embodiment of the present invention, as shown in fig. 1, the system for implementing automatic coding includes a vehicle a, a track b and a laser reflector c. Wherein the vehicle a runs on a track b, and the laser reflecting plate c can be arranged on the track b or other peripheral objects, such as a shelf or a wall. Further, as shown in fig. 2, a trolley wire e is fixed to the rail b, and a collector d is fixed to the vehicle a. Thus, the vehicle a can travel on the track b, and during the travel the vehicle a takes electrical energy from the current collector d via the trolley line e.
In addition, as shown in fig. 3, the vehicle a may include a vehicle body a1, and a glue application device a6 and a code pasting device a7 fixed to the vehicle body a 1. A laser rangefinder a2 is also attached to the vehicle body a 1. Therefore, when the vehicle for realizing automatic code pasting works, the vehicle a and the track b can be placed at the position needing code pasting and can be placed in a correct position before code pasting, and meanwhile, the position is calibrated to be the initial code pasting position. Then, the vehicle a starts and travels along the track b, and then the distance the vehicle a moves from the initial position is measured by the laser range finder a2 and the laser reflection plate c. When the position to be applied with the code is reached, the vehicle a stops.
It is worth mentioning that, when determining whether the vehicle a reaches the position to be applied with a sign, the following method may be adopted: and if the distance from the current position to the previous code pasting position is a preset code pasting distance, judging that the vehicle a reaches the position needing code pasting. Of course, when the distance from the current position of the previous barcode is the integral multiple of the preset barcode distance, it may be determined that the vehicle a reaches the position to be barcode.
As another embodiment of the present invention, the vehicle a may further include a control system, and when the position to be pasted is reached, the laser rangefinder a2 sends a signal to the control system installed on the vehicle a, so that the vehicle a completes the automatic pasting work under the control of the control system. Specifically, the process of automatically pasting the code includes:
the vehicle a stops with the glue applicator a6 on the vehicle a above the current position of the decal. And then the control system controls the gluing device a6 to glue at the position of the code, and after the gluing is finished, the control system controls the vehicle a to move forward. The vehicle a stops when reaching the preset designated position, and then the control system controls the code sticking device a7 to take the code and stick the code on the glued code sticking position. The above process may be repeated to automatically pad all pad locations.
In addition, preferably, the vehicle a further includes a side guide wheel a3, a driven wheel a4, and a driving wheel a5, as shown in fig. 3 and 4. The driving wheels a5 are arranged in a pair on the left and right of the rear position of the vehicle a, the driven wheels a4 are arranged in a pair on the left and right of the front position of the vehicle a, and the side guide wheels a3 are arranged in two pairs on the left and right of the vehicle a.
Thus, during the running of the vehicle a along the track b, the two pairs of driving wheels a5 and the two pairs of driven wheels a4 are supported on the upper surface of the track b, and the driving wheels a5 provide power for the vehicle a. The four pairs of side guide wheels a3 contact with the side surface of the track b and play a side guide role in the running process of the vehicle a, so that the vehicle a is ensured to run along a straight line without being deflected from side to side.

The lateral sliding block a604 is matched with the rubber cylinder lateral guide rail a605, and the lateral sliding block a604 can move laterally along the rubber cylinder lateral guide rail a 605. The traversing motor a610 drives the synchronous pulley a602 on one side to rotate, so as to drive the synchronous belt a603 to rotate, and finally drive the rubber sleeve mounting rack a607 to transversely move.
The longitudinal movement electric push rod a611 is fixedly connected with the longitudinal movement support a609, and the longitudinal movement electric push rod a611 can drive the longitudinal movement support a609 to longitudinally move, so that the glue cylinder mounting rack a607 is finally driven to longitudinally move; the lateral and longitudinal movement of the cartridge mount a607 allows the cartridge mount a607 to apply glue in the region "□".
