Example two
The difference between the present embodiment and the first embodiment is that the production carrier in the present embodiment is further provided with a vibration sensor, an acceleration sensor and a gyroscope, which are respectively used for collecting vibration data, acceleration data and deflection angle data.
The production carrier is provided with a mounting groove, and a verification device is arranged in the mounting groove.
The verification device comprises a moving block made of insulating materials, and the cross sectional area of the moving block is smaller than that of the mounting groove.
Two first metal contacts are fixed on the lower surface of the moving block and connected by a lead in the edge connecting block; the lower surface of the insulating block is also fixed with two permanent magnets with opposite magnetic poles;
the verification device further comprises a power supply, a control circuit board, two second metal contacts and two electromagnets with opposite magnetic poles.
The two second metal contacts and the two electromagnets are fixed in the mounting grooves;
after the electromagnets with the two opposite magnetic poles adsorb the permanent magnets with the two opposite magnetic poles, the two first metal contacts on the moving block can be respectively contacted with the two second metal contacts. In other words, the two electromagnets with opposite magnetic poles attract the two permanent magnets with opposite magnetic poles, so that the moving block can move to the specified position in the mounting groove.
The power supply is electrically connected with the control circuit board, and the control circuit board is electrically connected with the two electromagnets. The control circuit board is used for controlling the magnetic force of the two electromagnets. And the two second metal contacts are electrically connected with the control circuit board. When the two first metal contacts are not contacted with the two second metal contacts, the control circuit board can detect that the current loop is disconnected.
The vibration sensor, the acceleration sensor and the gyroscope are all electrically connected with the control circuit board, and the collected vibration data, the collected acceleration data and the collected deflection angle data are sent to the control circuit board.
The two-dimension code automatic mounting system further comprises a verification module, wherein the verification module is used for acquiring acceleration data, deflection angle data and vibration data from the control circuit board when the camera module is loaded to the production carrier;
the verification module is also used for judging whether the acceleration data exceeds an acceleration threshold or the deflection angle data exceeds a deflection angle threshold; when one of the vibration data ranges is met, the verification module is further used for judging whether the current vibration data belongs to a preset normal vibration data range or a preset abnormal vibration data range.
If the camera module belongs to the normal vibration data range, a mounting instruction is sent to the mounting module, and the mounting module directly mounts the two-dimensional code of the product for the camera module after receiving the mounting instruction; if the abnormal vibration data range is included, the verification module sends an analysis instruction to the analysis module, the analysis module receives the analysis instruction and analyzes whether the position of the camera module is accurate, if so, loading success information is generated, and if not, loading failure information is generated. The analysis module is also used for sending the loading success information or the loading failure information to the verification module.
When the verification module receives the loading failure information, taking the current vibration data as the reference data of the abnormal vibration data range; the verification module is also used for acquiring current loop information from the control circuit board, sending a reset instruction to the control circuit board if the current loop is disconnected, and sending a magnetic force reduction instruction to the control circuit board if the current loop is not disconnected. And after the control circuit board receives the reset instruction, the magnetic force of the electromagnet is increased until the current loop is conducted again, and then the magnetic force is restored to the preset value. And after the control circuit board receives the magnetic force reducing instruction, the preset value of the magnetic force is reduced.
And when the verification module receives the loading success information, acquiring current loop information from the control circuit board, and if the current loop is not disconnected, taking the current vibration data as the reference data of the normal vibration data range and correcting the abnormal vibration data range. And if the current loop is disconnected, taking the current vibration data as the reference data of the abnormal vibration data range.
When the camera module normally loads the production carrier, the position accuracy of the camera module can be ensured, so that when the position is accurate, whether the position of the camera module is accurate or not is judged again without an analysis module at every time, the time can be saved, and the production efficiency is improved.
When the robot arm is in contact with the production carrier due to insufficient operation precision, displacement of the production carrier is easily caused, and when the acceleration data exceeds the acceleration threshold or the deflection angle data exceeds the deflection angle threshold, the situation can be reflected. At this time, the camera module on the production carrier may move, resulting in deviation of the relative position. When the camera module moves, the camera module easily collides with the production carrier, so that the production carrier vibrates slightly. Therefore, the verification module is further configured to determine whether the current vibration data belongs to a preset normal vibration data range or a preset abnormal vibration data range. If belong to normal vibration data range, do not carry out other operations, show that the camera module does not appear moving, do not carry out other operations, if belong to predetermined abnormal vibration data range, whether the rethread analysis module judges camera module position accurate.
However, the abnormal vibration data range and the normal vibration data range are not always completely accurate initially, and need to be continuously corrected to be perfect. Moreover, when the abnormal vibration data range belongs to the preset abnormal vibration data range, the position of the camera module is also accurate, which may be that the abnormal vibration data range is not accurate, or may be a small probability event that the camera module returns to the accurate position after moving irregularly from the accurate position. In order to accurately correct the abnormal vibration data range, it is necessary to distinguish between the two cases. For this purpose, the present embodiment is provided with an authentication device. When the camera module removed, the movable block also can remove, leads to the disconnection of current circuit, can come the action that the camera module removed with the movable block in other words, avoided the camera module to return to this kind of little probability incident of accurate position again after moving irregularly. However, the preset value of the magnetic force needs to accurately simulate the friction force between the camera module and the production carrier to achieve the above effect, and therefore the preset value of the magnetic force needs to be adjusted, that is, the camera module moves, and the moving block does not move, which indicates that the preset value of the magnetic force is too large and needs to be lowered.
After the data sample is enough in the later stage, the abnormal vibration data range, the normal vibration data range and the preset value of magnetic force can be accurate enough, the abnormal vibration data range, the normal vibration data range and the current loop information are combined, even the camera module can be accurately judged whether to move by independently relying on the circuit loop information, and the camera module can be partially replaced or even completely replaced by image recognition according to actual conditions to judge whether the position of the camera module is accurate. The embodiment can also be applied to each processing link and transportation to judge whether the relative position of the camera module and the production carrier has deviation or not.
The above are merely examples of the present invention, and the present invention is not limited to the field related to this embodiment, and the common general knowledge of the known specific structures and characteristics in the schemes is not described herein too much, and those skilled in the art can know all the common technical knowledge in the technical field before the application date or the priority date, can know all the prior art in this field, and have the ability to apply the conventional experimental means before this date, and those skilled in the art can combine their own ability to perfect and implement the scheme, and some typical known structures or known methods should not become barriers to the implementation of the present invention by those skilled in the art in light of the teaching provided in the present application. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
