[0025] The working principle of the aging calibration detection equipment for the mainboard of a combustible gas detection device provided by the present invention is as follows: the control cabinets of various parts of the aging calibration detection equipment for the mainboard of the combustible gas detection device are electrically connected to the main controller, and various parts are coordinated by the main controller. The combustible gas detector mainboard puzzle 7 is fixedly connected with evenly distributed combustible gas detector small boards 9, and the edge of the combustible gas detector mainboard puzzle 7 is provided with an identification code 10, and the identification code 10 can use a bar code or a QR code. The combustible gas detector small board 9 is installed, and the contacts of all the combustible gas detector small boards 9 are led out to the puzzle power supply contacts 11 of the combustible gas detector mainboard puzzle 7. The centralized power supply method is adopted to effectively reduce the number of wiring, and the combustible gas detector mainboard puzzle 7 Each of them has a unique identification code 10, which is used to bind and record the product; aging, calibration, and detection of all information in the production process. This optimization can reduce the power contacts while increasing the output per unit time. The combustible gas detector main board panel 7 equipped with the combustible gas detector small board 9 is placed in the interior of the PCB board dedicated turnover basket 1. The PCB board loading machine 21 is controlled by the main controller. When starting work, the AGV car transfers the PCB board together with the turnover basket 1 from the transfer warehouse to the PCB board loading machine 21. The PCB board loading machine 21 pushes the combustible gas detector main board panel 7 layer by layer and transports it to the PCB docking station conveyor belt 22. A scanning mechanism is provided at the upper end of the PCB docking station conveyor belt 22. The combustible gas detector main board panel 7 is scanned by the scanner After the combustible gas detector mainboard panel 7 is scanned, the main controller will record the identification code 10, and bind it with the production information including the corresponding product model of the panel, the appearance of the panel, the aging voltage of the panel, the time required for aging of the panel, etc., to realize the initial transportation of the combustible gas detector mainboard panel 7 and wait for the next transportation. By rotating the PCB docking station conveyor belt width adjustment screw 23, the PCB docking station conveyor belt 22 is driven to adjust the width, and compatibility with combustible gas detector mainboard panels 7 of different sizes is achieved within a certain adjustable range. The robot control cabinet 33 receives the information that the combustible gas detector mainboard panel 7 is in place from the main controller, the robot control cabinet 33 controls the motor 344 to rotate, the robot grip adjustment screw 341 rotates, and the movable grip 343 is at two The movable hand grip 343 moves to make the distance between the two clamping claws 345 adapt to the size of the combustible gas detector main board puzzle 7. The robot body 32 drives the fixed claw to move so that the two clamping claws 345 clamp the combustible gas detector main board puzzle 7. The main controller instructs the combustible gas detector main board puzzle 7 to be placed in the empty space of the aging warehouse, and is preferably placed in the interior of the old chemical equipment PCB support seat 423. After the old chemical equipment PCB support seat 423 is fully filled, it is placed in the interior of the ordinary old chemical equipment 43. When the combustible gas detector main board puzzle 7 is placed in the interior of the old chemical equipment PCB support seat 423, the pneumatic control component 44 controls the external air pump to supply air and the controller for changing the direction of the air path controls the corresponding telescopic end of the cylinder 1 to be pushed out.The movable bottom plate 421 of the sampling aging chemical device descends, driving the probe pressure plate 424 to descend, so that the probe of the probe pressure plate 424 contacts the corresponding contact interface on the main board puzzle 7 of the combustible gas detector, so as to achieve communication between the product and the system. A data acquisition board and a power supply board are arranged on the aging dense rack body 41. The acquisition board receives and forwards the data collected by the probe pressure plate, and the acquisition board is then connected to the data system. The ordinary aging chemical device is connected to the power supply board. The function of the power supply board is to power on and monitor the on-off of the circuit. After the probe pressure plate 424 is in place, the self-locking spring 422 of the sampling aging chemical device will self-lock to ensure that the aging can proceed smoothly when the cylinder is damaged or the compressed gas production fails, and the communication is not interrupted. The ordinary aging chemical device 43 adopts right-angle corners The positioning method cleverly uses two adjacent right-angled sides of the product as product positioning, and the other two sides are used as free sides to be compatible with combustible gas detector mainboard panels 7 of different sizes. When the combustible gas detector mainboard panel 7 is put into place, the main controller will control the corresponding probe pressure plate 424 or the ordinary aging chemical installation 43 station to power on. If the power-on is successful, the main controller will record the power-on start time. If the power-on is unsuccessful, the system will issue an alarm and notify relevant personnel to handle it; during aging, the combustible gas detector mainboard panel 7 of the ordinary aging station only records the aging start time, and calculates the aging end time according to the system product information, and issues a prompt but does not power off. During the aging process, the main controller will monitor whether there is a power failure during the aging process, and will issue an alarm after a power failure; sampling aging chemical The combustible gas detector main board puzzle 7 not only records the aging time, but also establishes communication with the combustible gas detector small board 9, so it can monitor the changes of the internal data of the sensor during the aging process of the combustible gas detector small board 9 in real time, and transmit it to the main controller in real time through the wired communication port for data aggregation; this aging dense rack solution solves a series of problems such as the small production capacity of the existing production process, the large manual workload, the lack of data collection in the production process, and the difficulty in tracing the quality. Before the combustible gas detector main board puzzle 7 is placed in the assembly line tooling PCB board support seat 512, the self-locking buckle 513 is unlocked by pressing the self-locking buckle unlocking hole 514. When the robot body 32 drives the combustible gas detector main board puzzle 7 to be placed in the assembly line tooling PCB board support seat 5 After 12, the self-locking buckle 513 is reset to complete the self-locking. The two self-locking buckles 513 are respectively located on the front and rear sides of the panel power supply contact 11 to maintain the continuous power supply of the combustible gas detector main board panel 7. After being inserted, the electrical slip ring 53 is powered on for the assembly line tooling PCB board support seat 512. The application of the electrical slip ring 53 allows the product to be continuously and stably powered while rotating with the assembly line tooling 51. The turret divider 52 rotates the assembly line tooling 51 with the combustible gas detector main board panel 7 into place. The lower bin assembly 63 moves upward under the upward push of the telescopic end of the cylinder 2, and continues to move upward after supporting the assembly line tooling 51, and finally closes the mold with the upper bin assembly 62 to form a sealed cavity. The two sealed cavities of the bin body bracket 61 on the rear side are calibration bins.The two sealed cavities of the bin support 61 located at the front side are the detection bins. Then, the combustible gas is injected through the combustible gas injection port. The combustible gas is mixed in the closed bin through the fan 64 to achieve concentration balance, calibrate and test the required gas concentration, and dynamically configure as required according to the changes in the products produced. After the inspection is completed, the turret divider 52 rotates the assembly line tooling 51 with the combustible gas detector mainboard puzzle 7 to the next station, presses the self-locking buckle unlocking hole 514 to unlock the self-locking buckle 513, removes the combustible gas detector mainboard puzzle 7, and places the combustible gas detector mainboard puzzle 7 on the upper end of the two conveyor belts 82. The adjustable conveyor width adjustment screw 81 adjusts the width between the two conveyor belts 82 to adapt to combustible gas detector mainboard puzzles 7 of different sizes.
