DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Figure 1 The structural diagram of the marking and testing integrated device for a pan-tilt camera provided by an embodiment of the present invention, the marking and testing integrated device for a pan-tilt camera comprises: A PLC control system and a motion mechanism, wherein the motion mechanism is used to move the pan-tilt camera after the finished product is assembled to each workstation, wherein the work includes a laser marking module, an insulation withstand voltage detection module and a vacuum testing mechanism, and the PLC control system is connected to the motion mechanism and the laser marking module, the insulation withstand voltage detection module and the vacuum testing mechanism respectively; The laser marking module includes a marking component that matches the curvature of the pan-tilt camera. When the marking component is attached to the pan-tilt camera, it performs a one-time marking on the pan-tilt camera. The insulation withstand voltage detection module is used to perform insulation test on the pan-tilt camera after marking is completed; The vacuum testing mechanism is used to perform a sealing performance test on the pan / tilt camera after the insulation test.

[0019] The traditional marking process requires manual work, which is to mark first and then assemble the finished product. During the assembly process, there is a risk of wear and tear on the engraved content, which affects the product quality. After the finished product is assembled, it must be transported to the corresponding test device through a transmission device for various tests. Since the test device is completely independent of the laser marking, the production process is scattered and labor-intensive, affecting product production efficiency.

[0020] The embodiment of the present invention provides an integrated marking and testing device for a pan-tilt camera, which includes a PLC control system and a motion mechanism. The motion mechanism is used to move the pan-tilt camera after the finished product is assembled to each workstation. The work includes a laser marking module, an insulation withstand voltage detection module and a vacuum testing mechanism. The PLC control system is connected to the motion mechanism and the laser marking module, the insulation withstand voltage detection module and the vacuum testing mechanism respectively. The laser marking module includes a marking component that matches the curvature of the pan-tilt camera. When the marking component is attached to the pan-tilt camera, it performs a one-time marking on the pan-tilt camera. The insulation withstand voltage detection module is used to perform an insulation test on the pan-tilt camera after marking. The vacuum testing mechanism is used to perform a sealing performance test on the pan-tilt camera after the insulation test. The finished product is assembled first, and then the product is marked and tested in turn, so as to optimize the product process flow. In addition, the laser marking, insulation withstand voltage detection and vacuum testing are integrated, which reduces manual intervention, improves production efficiency and shortens the production cycle.

[0021] Based on any of the above embodiments, the embodiment of the present invention provides an integrated marking and testing device for a pan-tilt camera, wherein the motion mechanism includes: A moving electric cylinder, a slide block arranged on a guide rail, and a servo motor; The servo motor is connected to the moving electric cylinder through a coupling, and the rotational motion of the servo motor is converted into the motion of the moving electric cylinder; The moving electric cylinder is connected to the slider through a thread, and when the moving electric cylinder moves, the slider moves along the guide rail; The slider is used to carry the pan / tilt camera after the finished product is assembled; The guide rails connect the various workstations.

[0022] like Figure 2 As shown, during the operation of the motion mechanism, the workpiece is moved to the specified position by the motion electric cylinder to realize the action of each workstation.

[0023] Based on any of the above embodiments, the PLC control system is used to send working parameters to the laser marking module when the pan-tilt camera is transported to the laser marking station by the motion system, so that the marked component performs the marking task according to the working parameters; the working parameters are determined according to different types of materials and the required marking effects.

[0024] In an embodiment of the present invention, the laser marking module further includes a smoke purifier, which is used to absorb smoke generated during the marking process and filter the smoke before discharging it.

[0025] like Figure 3As shown, when the workpiece to be measured runs to the laser marking station, the PLC drives the laser marking machine to mark the workpiece, and the smoke generated during the marking process is filtered through the smoke purifier and then discharged.

[0026] Based on any of the above embodiments, the insulation withstand voltage detection module includes: Pressure test cylinder, pressure test limit bearing and insulation pressure tester; The withstand voltage test cylinder is used to provide mechanical power for the insulation withstand voltage test module to push the test probe into the inside of the pan / tilt camera; the withstand voltage test limit bearing is installed on the movement path of the withstand voltage test cylinder to limit the maximum stroke of the withstand voltage test cylinder; The insulation withstand voltage tester is used to apply a preset voltage to the pan-tilt camera to check whether the insulation resistance value of the pan-tilt camera meets the standard requirements.

[0027] like Figure 4 As shown in the figure, when the workpiece is transported to the insulation withstand voltage test station, the PLC control system will issue a command to start the cylinder. Prior to this, the system may first confirm that the workpiece is correctly in place through sensors. The cylinder pushes the communication element (such as a test probe) to accurately insert it into the plastic core of the workpiece to form an electrical connection. The limit bearing plays a key role in this process to ensure that the cylinder does not exceed the set stroke range. After the communication element is successfully connected to the workpiece, the PLC will send a start command and other necessary configuration parameters such as the test voltage level and duration to the insulation withstand voltage tester through the RS232 serial interface. After receiving the command, the insulation withstand voltage tester applies voltage to the workpiece according to the preset conditions and monitors its insulation performance. If the workpiece does not break down within the specified time, it is considered that its insulation performance is qualified; otherwise, the fault information is recorded for subsequent analysis. After the test is completed, the insulation withstand voltage tester will feed back the test results to the PLC. If it is a qualified product, the system will continue to the next process; if it is unqualified, it may trigger an alarm or take other measures. Finally, the cylinder retracts, disconnects from the workpiece, and prepares for the arrival of the next workpiece.

[0028] Based on any of the above embodiments, the vacuum detection mechanism includes: Vacuum testing cylinders, vacuum testing limit bearings, vacuum pumps and vacuum pressure testers; The vacuum detection cylinder is used to provide mechanical power for the vacuum detection mechanism, push the vacuum valve to the air hole position of the pan-tilt camera, and ensure that the vacuum pump can be effectively connected to the pan-tilt camera; The vacuum detection limit bearing is installed on the movement path of the vacuum detection cylinder and is used to limit the maximum stroke of the vacuum detection cylinder; The vacuum pump is used to extract air from the inside of the pan-tilt camera to reduce the internal pressure of the pan-tilt camera; The vacuum pressure detector is used to monitor the pressure changes inside the pan-tilt camera in real time, and convert the measured pressure value into an analog voltage signal and transmit it to the PLC control system; The PLC control system is also used to receive the analog voltage signal transmitted by the vacuum pressure detector, record the pressure drop at preset time intervals, and determine whether the vacuum degree meets the process requirements based on the pressure drop amplitude per unit time.

[0029] like Figure 5 As shown in the figure, when the workpiece is transported to the vacuum test station, the PLC control system will issue a command to start the cylinder. Before that, the system may confirm that the workpiece is correctly in place through sensors. The cylinder pushes the vacuum valve to accurately insert it into the air hole position of the workpiece to form a tight connection. The limit bearing plays a key role in this process to ensure that the cylinder does not exceed the set stroke range. After the vacuum valve is successfully connected to the workpiece, the vacuum pump starts to extract air from the inside of the workpiece to reduce its internal pressure. At the same time, the vacuum pressure detector monitors the pressure changes inside the workpiece in real time and sends this data to the PLC in the form of a 0-10V analog voltage signal. After receiving the pressure signal from the vacuum pressure detector, the PLC records the pressure drop at a preset time interval and determines whether the vacuum degree meets the process requirements based on the pressure drop amplitude per unit time. If the pressure drop rate is within the allowable range, the vacuum degree is considered qualified; otherwise, it is marked as unqualified. After the test is completed, the PLC will decide on the subsequent steps based on the judgment result, such as continuing the production process or issuing an alarm prompt. Finally, the cylinder retracts, disconnecting the vacuum valve from the workpiece to prepare for testing the next workpiece.

[0030] Based on any of the above embodiments, it also includes an information module, and the information module includes a human-machine interface and an I / O interface; The I / O interface is used to collect various parameters in the production process in real time; The human-machine interface is used to provide an interactive interface between the operator and the device and receive input instructions from the user; The PLC control system is also used to mark and test the pan-tilt camera according to various parameters in the production process and the user's input instructions.

[0031] Based on any of the above embodiments, it also includes a safety module, wherein the safety module includes a physical protection device and an emergency stop device; The physical protection device is used to physically protect the test task; The emergency stop device is used to quickly cut off the power supply and stop the marking task or the testing task in an emergency.

[0032] In the embodiment of the present invention, multi-level safety protection measures are important to ensure the safety of operators and the stable operation of equipment. Specifically, components such as safety doors, emergency stop buttons and safety relays are respectively arranged in different positions and each plays a unique role.

[0033] Safety doors are usually installed at the entrance and exit of equipment, as well as any place where personnel may need to enter or approach the interior of the equipment for maintenance or adjustments.

[0034] Prevent unauthorized personnel from accidentally contacting operating mechanical parts or electrical components to avoid collisions or electric shocks. Send status information to the PLC so that the system can monitor the status of the safety door in real time to ensure that the equipment is allowed to continue operating only under safe conditions.

[0035] Emergency stop buttons should be easily accessible and prominently located in key locations around the equipment, including but not limited to near the operating panel, on both sides of the equipment, and next to any workstation where there may be risks. Once the emergency stop button is pressed, it will trigger the emergency braking procedure, quickly interrupt all power supply, and stop the entire system immediately, allowing for quick response even in the most adverse situations.

[0036] Safety relays are usually located in the control cabinet as part of the electrical control system, responsible for processing signals from various sensors (such as safety door switches) and other safety-related inputs. They can provide an additional layer of safety. Even if the main control system fails, the safety relay can still independently perform critical safety functions, such as cutting off power or sounding an alarm.

[0037] In the embodiments of the present invention, the safety protection measures not only effectively reduce potential risks, but also improve the reliability and efficiency of the overall production. Through reasonable layout and clear functional division of labor, it is ensured that sufficient safety protection can be provided to users even in a complex and changeable operating environment.

[0038] Based on any of the above embodiments, it also includes: a host computer, which is connected to the PLC control system and is used to receive and store test data and generate a test report.

[0039] Traditional marking and testing methods are limited by the instability of manual operations. The insulation and voltage withstand test requires manual connection of the test device, which poses the risk of wrong connection or missed connection. The vacuum test requires manual pressing of the pressure pump and visual observation of the instrument display, making it difficult to ensure detection accuracy. In the embodiments of the present invention, the insulation and voltage withstand test and vacuum test of the product undergo essential changes in the device connection and data recording methods. The electric cylinder is used to achieve precise positioning and movement of the product, and the host computer is used to record the detection data in real time, thereby improving the detection accuracy by more than 50%.

[0040] like Figure 6 As shown, the PTZ camera is a Y-type PTZ camera, which automatically completes insulation withstand voltage, vacuum testing, marking, etc., reduces manual labor intensity, improves production efficiency, improves detection accuracy, and realizes information-based shared management of detection data. The marking test process for the Y-type PTZ camera produced on the production line includes: (1) The code reader automatically reads the QR code information on the Y-type PTZ camera housing; (2) Use electric cylinders to achieve precise positioning and movement of the Y-type pan-tilt camera; (3) Laser marking system realizes product marking and smoke and dust removal; (4) PLC controls the vacuum pump to detect the sealing performance of the camera; (5) Use PLC to control the insulation withstand voltage tester to perform insulation test on the PTZ; (6) Use PLC to control the laser marking machine through the I / O interface to mark the product; (7) Collect and analyze product data through the host computer.

[0041] The traditional manual operation process is: (1) marking; (2) finished product assembly; (3) insulation withstand voltage test; (4) vacuum test. Because the components of the product are heavy and the surface of the product is curved, marking must be done twice, and secondary loading is required for marking; manual operation requires marking before assembling the finished product. There is a risk of wear and tear of the marked content during the assembly process, which affects the product quality. The process is scattered and labor-intensive. In addition, the disadvantage of the existing technical solution is that it does not integrate the three processes of insulation withstand voltage test, vacuum test and marking. The detection accuracy is not high enough.

[0042] The embodiment of the present invention first assembles the finished product, and then uses a special machine to mark, perform insulation withstand voltage test and vacuum test on the product in sequence, thereby optimizing the product process flow; and the marking system includes a smoke and dust removal function to ensure the safety of the operators. At the same time, the insulation withstand voltage test and vacuum test of the product undergo essential changes in the device connection and data recording methods, and the electric cylinder is used to achieve precise positioning and movement of the product, thereby improving the detection accuracy.

[0043] The integrated marking and testing device for a pan-tilt camera provided by the present invention integrates laser marking, insulation withstand voltage testing and vacuum testing, reduces manual intervention, improves production efficiency and shortens the production cycle; at the same time, it adopts multi-level safety protection measures, such as safety doors, emergency stop buttons and safety relays, which meet the SIL2 safety level requirements and ensure personal safety during equipment operation.

[0044] An embodiment of the present invention further provides a pan-tilt camera, which is obtained by performing a marking test using the integrated marking and testing device for a pan-tilt camera as described in the above embodiment.

[0045] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0046] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the relevant technology can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiment.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
