Detailed Embodiment

[0032] The following are specific embodiments in conjunction with the drawings to describe the present utility model in detail.

[0033] AsFigure 1 As shown in the figure, the safety protection system for the appearance inspection and test operation of the initiator of the present utility model includes an inspection operation safety protection subsystem 1 and a test operation safety protection subsystem 2;

[0034] The outer metal frame structure of the inspection operation safety protection subsystem 1 is divided into two parts: an upper frame assembly 4 and a lower frame assembly 5. The upper frame assembly 4 is made of industrial-grade aluminum profiles and is connected to the lower frame assembly 5 in a threaded connection form to ensure the integrity of the upper and lower frames; the lower frame assembly 5 is welded with profiles. It is also the fixing frame of the manipulator, with space left inside for the manipulator control cabinet 51 and the power supply box 52, which greatly saves space and enhances the overall aesthetics. The outside of the upper frame assembly 4 uses composite bulletproof materials as the explosion isolation unit, combined with the aluminum profile frame structure, which can better achieve the explosion isolation function while taking into account portability and aesthetics. The explosion isolation unit is the structural main body of the entire appearance inspection safety protection subsystem and also the basic stress carrier. It confines the detonation energy in a narrow space, effectively weakening or even preventing the diffusion of explosion products, and protecting the test personnel within a 360° range.

[0035] The inspection operation safety protection subsystem 1 also includes a servo turntable 41, a camera 42, a photographing robot 43, and a grasping robot 44 arranged inside the upper frame assembly 4; on the premise of making full use of space, it can not only ensure the basic movement of the equipment, but also make the appearance more concise and integral. The photographing robot 43, the grasping robot 44, and the servo turntable 41 are arranged on the bottom plate of the upper frame assembly 4, and the photographing robot 43 and the grasping robot 44 are respectively arranged on both sides of the servo turntable 41; the grasping robot 44 is arranged close to the loading and unloading bracket 3.

[0036] The inspection operation safety protection subsystem 1 also includes a loading and unloading bracket 3 arranged at the upper edge of the upper part of the lower frame assembly 5 and a robot control cabinet 51 and an electric control cabinet 52 arranged inside the lower frame assembly 5. The upper surface of the loading and unloading bracket 3 is divided into a non-conforming area, a qualified area, and a to-be-inspected area, which are used to store qualified products, non-conforming products, and products to be inspected respectively. The loading and unloading bracket 3 is mainly composed of a tray 32, a product placement tooling 31, and a loading and unloading bracket mechanical interface 33, as Figure 3 shown. The loading and unloading bracket 3 is the starting storage unit of the entire inspection operation safety protection subsystem. In the whole system, it is the starting point of all actions and has the function of classifying and storing products. Its main function is: placing the product to be inspected on the loading and unloading bracket 3 and waiting for the industrial robot to grab the uninspected parts and place the inspected parts. One side of the tray 32 is fixedly connected to the lower frame assembly 5 through the loading and unloading bracket mechanical interface 33, and the product placement tooling 31 is arranged thereon. The loading and unloading bracket mechanical interface 33 adopts The cylindrical pin and the countersunk head screw are fastened to the lower frame assembly 5, and threaded holes are provided on the lower frame assembly 5. At the same time, positioning pin holes are provided on the product placement tooling 31 to ensure the accurate positioning of the tray.

[0037] To accommodate products to be detected with different external dimensions, the specifications of the products to be detected are integrated and classified, and one type of tray is suitable for one or more types of products to be detected. Then, a few types of trays 32 are fixed on the product placement tooling 31 and fixed. According to the requirements for storing pyrotechnic devices, the test piece belongs to a sensitive electrical component, and a split structure design is required to reduce the possibility of danger occurring. Under the known limit dimensions, all the specifications and models of the products to be detected are covered.

[0038] To prevent misoperation and ensure safety during the appearance inspection process, the upper frame assembly 4 is also provided with a safety door interlock unit; it has the functions of manually opening and closing the door and automatically opening and closing the door according to signals: the safety door interlock unit mainly includes a safety door 410, a cylinder 412, and a guide rail 46.

[0039] Among them, the cylinder block of the cylinder 412 is connected to the main body of the upper frame assembly 4, the end of the piston rod of the cylinder 412 is fixedly connected to the safety door 410, the lower part of the safety door 410 is connected to the guide rail 46, and the guide rail 46 is fixedly connected to the main body of the lower frame assembly 5.

[0040] The cylinder 412 is used to drive the safety door 410 to move on the guide rail 46 by telescoping. The safety door 410 is also provided with an electromagnetic lock 49. When the cylinder 412 moves to the maximum stroke, after the proximity switch outputs a signal, the cylinder 412 stops operating, and the electromagnetic lock 49 is started, and the safety door 410 is locked. After the appearance inspection is completed, the electromagnetic lock 49 is closed, and the cylinder 412 retracts, and the safety door 410 is fully opened.

[0041] The working principle of the inspection operation safety protection subsystem 1 is as follows:

[0042] After the operator places the product to be inspected on the inspection area of the loading and unloading bracket 3, the system is started. The grasping robot 44 grasps and moves the product to be inspected from the inspection area of the loading and unloading bracket 3 to the detection area of the image acquisition robot 43. The grasping robot 44 adjusts the posture of the product to be inspected, and then the image acquisition robot 43 completes the image acquisition of the unclamped part of the product to be inspected. After the image acquisition is completed, the grasping robot 44 places the product to be inspected on the servo turntable 41, and rotates the servo turntable 41 to adjust the posture of the product to be inspected, and completes the image acquisition of the part of the product to be inspected that is clamped and blocked by the grasping robot 44. The operator judges the quality of the product through the acquired image of the product to be inspected at the control terminal. After the second image acquisition is completed, if the determination still cannot be made, manual control is adopted for the third image acquisition, and finally the background determination is carried out; the grasping robot 44 grasps the product to be inspected according to the judgment result and places it in the corresponding area of the loading and unloading bracket 3, that is, the qualified area or the unqualified area.

[0043] Among them, the system performs manual teaching sampling on the image acquisition positions with detection requirements, uses the obtained robot position data, and adopts the method of offline programming to concatenate the position data and solidify the trajectory. Using the front-end video vision, it can directly observe in real time through the display unit of the software platform, and optimize and adjust the program according to the corresponding offsets to achieve the stability of the robot path. The test operation safety protection subsystem includes a test operation explosion-proof unit, a status monitoring unit, a pressure relief and explosion vent unit, and a sensor unit.

[0044] The whole of the test operation safety protection subsystem 2 is wrapped with composite bulletproof materials on the outer frame 24 to form a test operation explosion-proof unit to ensure the explosion-proof performance. It internally has a sensor unit including temperature and humidity sensors to detect the test operation environment in real time. There are aviation plugs connected inside and outside to ensure the smooth progress of the experiment. A safety door 22 is provided on the side. After the safety door is closed, the experiment starts under manual control.

[0045] The outer metal frame 24 is made of industrial aluminum profiles, with composite bulletproof materials attached outside. The industrial aluminum profiles are used to fix the composite explosion-proof materials by taking advantage of the convenient installation of industrial aluminum profiles. The specific design is as Figure 8 shown:

[0046] In order to prevent unpredictable risks, a mechanical pressure relief and explosion vent unit 23 is added to the sealing top plate 21 of the test operation explosion-proof unit, which is realized by using an aluminum alloy punching plate. The aluminum alloy punching plate is installed on the upper part of the test operation main body, one inside and one outside. The upper and lower layers of punching adopt a staggered structure, effectively avoiding debris from entering or fragments generated by internal combustion explosion from flying out. The pressure relief area can be calculated according to the pressure resistance strength of the regional structure and a specific coefficient, and the required effective pressure relief area can be obtained through the pressure difference inside and outside the wall to meet the engineering requirements, thus ensuring the universality of the mechanical pressure relief port. The specific design is as Figure 9as shown

[0047] The working principle of the test operation safety protection subsystem 2 is as follows:

[0048] The operator places the product to be tested into the test operation safety protection subsystem 2. After connecting all the interfaces for performance testing, the safety door is manually closed, and then the testing starts. After the operator determines whether the product under test is qualified in the background of the control terminal, the safety door 24 is manually opened and the tested product is taken out.

[0049] The inspection operation safety protection subsystem 1 is also provided with a sensor unit and a status monitoring unit; the status monitoring unit is mainly used to observe the motion state of the manipulator; the sensor unit detects the temperature and humidity information in real time. Once the requirements are not met, the system will alarm and automatically stop the operation. The signals of the temperature and humidity sensors are collected, and the temperature value and humidity value are calculated. In the host computer software, the first-level warning line and the second-level warning line of temperature and humidity are set respectively. When the second-level warning line is exceeded, corresponding prompts are given, and when the first-level warning line is exceeded, the system alarms and stops. The sensor control process is as Figure 10 as shown

[0050] as Figure 11 as shown, it is the opening and closing control process of the safety door in the upper frame assembly 4: After giving the closing or opening command, the PLC controls the actions of each solenoid valve according to the state of the signal switch on the safety door, realizing the closing or opening action. And the process of opening or closing the door is monitored. When the set time has passed and the PLC still has not received the signal that the door is opened or closed in place, the PLC outputs an alarm signal and the system stops.

[0051] as Figure 12 as shown, it is the automatic detection control process, including the signal interaction and control process between the PLC and the robot, camera, light source and turntable.

[0052] In summary, the above is only the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
