Description

Technical Field

[0001] The present invention relates to the technical field of combustible gas detection, and specifically to an aging calibration detection device for the main board of a combustible gas detection device. Background Technique

[0002] In recent years, gas safety accidents have occurred frequently at home and abroad. Gas safety has been highly valued by relevant departments. Therefore, the demand for combustible gas detection device products has increased sharply. Combustible gas detection devices are applicable to pipeline natural gas, liquefied petroleum gas, and artificial gas. After connecting an electromagnetic cut-off valve, they have the functions of detecting combustible gas in the air, emitting an alarm sound, and closing the gas valve, that is, they can automatically cut off the gas and emit an alarm sound when the pipeline leaks or falls off, avoiding the occurrence of safety accidents. After finding out the cause of the fault, eliminating the fault and the gas concentration in the air returning to the safe value, the electromagnetic cut-off valve knob can be manually pulled up to restore the gas supply and continue to ensure the safety of gas use. With the sharp increase in the demand for combustible gas detection devices, the original production enterprises are rapidly expanding production capacity, and many new enterprises have also started production. Factors such as new employees in old enterprises being unskilled, production equipment production capacity not keeping up, single function, no control in the production process, reduction of detection links, and chaotic process management making product quality impossible to trace, etc., have led to the performance and quality of combustible gas detection devices, which are originally gas safety products, not being guaranteed, and there are great safety hazards. For this reason, we propose an aging calibration detection device for the main board of a combustible gas detection device. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This combustible gas detection device main board aging calibration detection equipment has the following advantages:

[0020] 1. This combustible gas detection device main board aging calibration detection equipment can either be used alone in cooperation with manual labor for production or be connected in series to form a production line to achieve automated production, improving production efficiency. An enterprise can order equipment for corresponding processes according to actual production needs. After the order volume increases, other equipment can be gradually invested to reduce the investment pressure on the enterprise.

[0021] 2. Each mainboard of the combustible gas detector has a unique identification code, which is used to bind and record the product; all information of the aging, calibration, and testing production process, all production data is bound to the product barcode, and unqualified products are automatically eliminated, which not only realizes quality traceability, but also ensures that unqualified products will not be mixed with qualified products.

[0022] 3. After the combustible gas detector mainboard is placed inside the tooling, the combustible gas detector mainboard of the ordinary aging position only records the start time of aging, while the combustible gas detector mainboard of the sampling aging position not only records the aging time, but also establishes communication with the combustible gas detector small board, which can monitor the changes in the internal data of the sensor during the aging process of the combustible gas detector small board in real time, and proposes a new aging idea, which not only controls the power-on status and uninterrupted aging time of the entire aging process of the product, but also has a sampling aging position to record the internal data of the product in real time during the aging process of the product. It is convenient for manufacturers to control product quality and accelerate product updates and iterations.

[0023] 4. The distance between the two clamping jaws is adjustable. Ordinary old chemical equipment adopts the right-angle corner positioning method, and cleverly uses the two adjacent right-angle sides of the product as product positioning. The other two sides are used as free edges to be compatible with different sizes of combustible gas detector mainboard panels. The assembly line tooling PCB board support seat, old chemical equipment PCB support seat and probe pressure plate can be quickly replaced. The plan proposes compatibility with products and compatibility with similar products to achieve multiple uses of one machine, which greatly reduces the investment pressure on enterprises.

[0024] 5. The lower bin body assembly moves upward, and continues to move upward after supporting the assembly line tooling, and finally closes the mold with the upper bin body assembly to form a sealed cavity. The two sealed cavities of the bin body bracket on the rear side are calibration chambers, and the two sealed cavities of the bin body bracket on the front side are detection chambers. Combustible gas is then injected through the combustible gas injection port. The new calibration and detection scheme greatly reduces the consumption of calibration and detection gas, which not only saves the production cost of the enterprise, but also contributes to energy conservation and emission reduction of the production enterprise.

Specific implementation mode

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figure 1-13 , this embodiment provides a technical solution: a combustible gas detection device main board aging calibration detection device, including a PCB upper board mechanism 2, a robot unit 3, a PCB board aging library unit 4, a calibration detection turret conveyor line unit 5 and a calibration detection chamber 6;

[0041] PCB upper board mechanism 2: A special turnover basket 1 for PCB boards is placed inside it. The PCB upper board mechanism 2 includes a PCB upper board machine 21, a PCB connecting table conveyor belt 22 and a PCB connecting table conveyor belt width adjustment screw 23. A special turnover basket 1 for PCB boards is placed inside the PCB upper board machine 21. A PCB connecting table conveyor belt width adjustment screw 23 is arranged on the right side of the PCB upper board machine 21. The upper sides of the fixed end and the movable end of the PCB connecting table conveyor belt width adjustment screw 23 are both provided with a PCB connecting table conveyor belt 22. The input ends of the PCB upper board machine 21, the PCB connecting table conveyor belt 22 and the PCB connecting table conveyor belt width adjustment screw 23 are all electrically connected to the output end of the main controller. The combustible gas detector main board splice plates 7 equipped with combustible gas detector small boards 9 are respectively placed inside the special turnover basket 1 for PCB boards. The PCB upper board machine 21 is controlled to operate by the main controller. When starting to work, the AGV cart transports the PCB board together with the turnover basket 1 from the transfer warehouse to the PCB upper board machine 21. The PCB upper board machine 21 pushes out the combustible gas detector main board splice plates 7 layer by layer and transports them to the PCB connecting table conveyor belt 22. A code scanning mechanism is arranged at the upper end of the PCB connecting table conveyor belt 22. The combustible gas detector main board splice plates 7 are scanned by the code scanning mechanism. The main controller will record the identification code 10 of the combustible gas detector main board splice plates 7 and bind it with the production information including the corresponding product model of the splice plate, the splice plate shape, the splice plate aging voltage, the time required for splice plate aging, etc., to realize the preliminary transfer of the combustible gas detector main board splice plates 7 and wait for the next transfer. By rotating the PCB connecting table conveyor belt width adjustment screw 23, the PCB connecting table conveyor belt 22 is driven to adjust the width, and different sizes of combustible gas detector main board splice plates 7 can be compatible within a certain adjustable range;

[0042] Robot unit 3: It is arranged on the right side of the PCB loading mechanism 2. The robot unit 3 includes a robot base 31, a robot body 32, a robot control cabinet 33, and a robot gripper 34. The robot base 31 is placed on the right side of the PCB loader 21. The aging dense rack body 41 on the left is located between the PCB loader 21 and the robot base 31. The robot control cabinet 33 is placed on the right side of the robot base 31. The upper end of the robot base 31 is fixedly connected to the robot body 32. One end of the robot body 32 away from the robot base 31 is fixedly connected to the robot gripper 34. The input end of the robot body 32 is electrically connected to the output end of the robot control cabinet 33. The robot control cabinet 33 is bidirectionally electrically connected to the main controller. The robot gripper 34 includes a robot gripper adjustment screw 341, a support shaft 342, a movable gripper 343, a motor 344, and a jaw 345. One end of the robot body 32 away from the robot base 31 is provided with a fixed jaw 12. The middle of the finger 13 at the upper end of the fixed jaw 12 is rotatably connected to the robot gripper adjustment screw 341. The left and right ends of the finger 13 at the upper end of the fixed jaw 12 are both fixedly connected to the support shaft 342. The robot gripper adjustment screw 341 and the two support shafts 342 both pass through the finger 13 at the lower end of the fixed jaw 12. The movable gripper 343 is slidably connected between the lower ends of the two support shafts 342. The lower end of the robot gripper adjustment screw 341 is threadedly connected to the middle of the movable gripper 343. The outside of the finger 13 at the upper end of the fixed jaw 12 is fixedly connected to the motor 344. The output shaft of the motor 344 is fixedly connected to the upper end of the robot gripper adjustment screw 341. The opposite outer sides of the finger 13 at the upper end of the fixed jaw 12 and the movable gripper 343 are both fixedly connected to the jaw 345. The input end of the motor 344 is electrically connected to the output end of the robot control cabinet 33. When the robot control cabinet 33 receives the in-place information of the assembled board 7 of the combustible gas detector main board from the main controller, the robot control cabinet 33 controls the motor 344 to rotate. The robot gripper adjustment screw 341 rotates, and the movable gripper 343 slides between the two support shafts 342. The movable gripper 343 moves, so that the distance between the two jaws 345 adapts to the size of the assembled board 7 of the combustible gas detector main board. The robot body 32 drives the fixed jaw to move, so that the two jaws 345 clamp the assembled board 7 of the combustible gas detector main board and place it into the empty space in the aging library through the main controller's instruction. The pneumatic control component 44 controls the power-on of the workstation and feeds back the product information to the main controller. The pneumatic control component 44 uses a PLC controller and preferentially places it inside the internal PCB support 423 of the aging tooling. After the internal PCB support 423 of the aging tooling is fully filled, it is then placed inside the ordinary aging tooling 43;

[0043] PCB Board Aging Library Unit 4: It includes an aging compact shelf body 41, a sampling aging tooling 42, a general aging tooling 43, and a pneumatic control component 44. Aging compact shelf bodies 41 are placed on the left and right sides and the rear side of the robot unit 3. The aging compact shelf body 41 on the left is located between the PCB loading mechanism 2 and the robot unit 3. Pneumatic control components 44 and evenly distributed sampling aging toolings 42 are provided at the lower ends of the aging compact shelf bodies 41, and evenly distributed general aging toolings 43 are provided at the upper ends of the aging compact shelf bodies 41. The sampling aging tooling 42 includes a sampling aging tooling movable bottom plate 421, a sampling aging tooling self-locking spring 422, an aging tooling PCB support seat 423, and a probe pressure plate 424. Evenly distributed aging tooling PCB support seats 423 are fixedly connected to the lower ends of the aging compact shelf bodies 41. Slide columns are slidably connected to the four corners of the aging tooling PCB support seat 423. A probe pressure plate 424 is fixedly connected between the upper ends of the four slide columns located on the same aging tooling PCB support seat 423. Sampling aging tooling self-locking springs 422 are provided at the lower ends of the slide columns. A sampling aging tooling movable bottom plate 421 is fixedly connected between the lower ends of the four sampling aging tooling self-locking springs 422 located on the same aging tooling PCB support seat 423. A cylinder 1 is fixedly connected to the middle of the lower surface of the aging tooling PCB support seat 423. The lower ends of the telescopic ends of the cylinder 1 are respectively fixedly connected to the upper surfaces of the vertically adjacent sampling aging tooling movable bottom plates 421. The cylinder 1 is arranged in cooperation with the pneumatic control component 44 located on the same aging compact shelf body 41. After the combustible gas detector main board splice plate 7 is placed inside the aging tooling PCB support seat 423, the pneumatic control component 44 controls the external air pump to supply air, and the controller for changing the air path direction controls the telescopic end of the corresponding cylinder 1 to push out. The sampling aging tooling movable bottom plate 421 descends, driving the probe pressure plate 424 to descend, so that the probes of the probe pressure plate 424 contact the corresponding contact interfaces on the combustible gas detector main board splice plate 7, achieving communication between the product and the system. A data acquisition board and a power supply small board are provided on the aging compact shelf body 41. The acquisition board receives and forwards the data collected by the probe pressure plate, and then the acquisition board is connected to the data system. The general aging tooling is connected to the power supply small board. The function of the power supply small board is to be responsible for power-on and monitoring the on-off of the circuit. After the probe pressure plate 424 is in place, the sampling aging tooling self-locking spring 422 will self-lock, ensuring that aging can still proceed smoothly even when the cylinder 1 is damaged or there is a production compressed gas failure, so as not to cause communication interruption. The general aging tooling 43 uses the right-angle edge positioning method, cleverly using two adjacent right-angle sides of the product as product positioning, and the other two sides as free sides to be compatible with combustible gas detector main board splice plates 7 of different sizes. After the combustible gas detector main board splice plate 7 is placed in place, the main controller will control the corresponding probe pressure plate 424 or the general aging tooling 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 not successful, the system will issue an alarm and notify relevant personnel to handle it;During aging, the motherboard splicing board 7 of the combustible gas detector at the ordinary aging station only records the start time of aging, calculates the end time of aging according to the system product information, and gives a prompt but does not cut off the power. During the aging process, the master controller will monitor whether there is a power failure during the aging process, and will give an alarm after a power failure; the motherboard splicing board 7 of the combustible gas detector at the sampling aging station not only has to record the aging time, but because it has established communication with the small board 9 of the combustible gas detector, it can monitor the change of the internal data of the sensor during the aging process of the small board 9 of the combustible gas detector in real time, and transmit it to the master controller in real time through the wired communication port for data aggregation; this aging dense rack solution solves a series of problems such as small production capacity, large manual workload, no data collection during the production process, and difficult quality traceability in the existing production process;

The self-locking buckles 513 are respectively arranged in cooperation with the vertically adjacent self-locking buckle unlocking holes 514. The input ends of the conveyor line tooling PCB board support seats 512 are all electrically connected to the output end of the electrical slip ring 53. Before the motherboard splicing board 7 of the combustible gas detector is placed in the conveyor line tooling PCB board support seat 512, the self-locking buckle 513 is unlocked by pressing the self-locking buckle unlocking hole 514. After the robot body 32 drives the motherboard splicing board 7 of the combustible gas detector to be placed in the conveyor line tooling PCB board support seat 512, the self-locking buckle 513 resets to complete self-locking. The two self-locking buckles 513 are respectively located on the front and back sides of the splicing board power supply contact 11 to keep the motherboard splicing board 7 of the combustible gas detector continuously powered. After being placed, the electrical slip ring 53 powers on the conveyor line tooling PCB board support seat 512. The application of the electrical slip ring 53 enables the product to be continuously and stably powered while rotating with the conveyor line tooling 51;

[0048] The working principle of a main board aging calibration detection device for a combustible gas detection device provided by the present invention is as follows: The control cabinets of each part of the main board aging calibration detection device for this combustible gas detection device are electrically connected to the main controller. Through the main controller, each part is coordinated. Inside the main board splice 7 of the combustible gas detector, there are evenly distributed small boards 9 of the combustible gas detector. An identification code 10 is set on the edge of the main board splice 7 of the combustible gas detector. The identification code 10 can use a bar code or a QR code. With the small boards 9 of the combustible gas detector installed, the contacts of all the small boards 9 of the combustible gas detector are led out to the splice power supply contacts 11 of the main board splice 7 of the combustible gas detector. By adopting a centralized power supply method, the number of wiring is effectively reduced. Each main board splice 7 of the combustible gas detector has a unique identification code 10 for binding and recording products; all information in the production processes of aging, calibration, and detection. This optimization can increase the production per unit time while reducing the power contacts. The main board splice 7 of the combustible gas detector with the small boards 9 of the combustible gas detector installed is respectively placed inside the special turnover basket 1 for PCB boards. The PCB loading machine 21 operates under the control of the main controller. When starting to work, the AGV cart transports the PCB board together with the turnover basket 1 from the transfer warehouse to the PCB loading machine 21. The PCB loading machine 21 pushes out the main board splice 7 of the combustible gas detector layer by layer and conveys it to the conveyor belt 22 of the PCB connection table. A code scanning mechanism is arranged at the upper end of the conveyor belt 22 of the PCB connection table. The main board splice 7 of the combustible gas detector is scanned by the code scanning mechanism. The main controller will record the identification code 10 of the main board splice 7 of the combustible gas detector and bind it with production information including the corresponding product model of the splice, the splice shape, the splice aging voltage, the time required for splice aging, etc., to achieve the preliminary transfer of the main board splice 7 of the combustible gas detector and wait for the next transfer. By rotating the width adjustment screw 23 of the conveyor belt of the PCB connection table, the conveyor belt 22 of the PCB connection table is driven to adjust the width, and compatibility with main board splices 7 of different sizes is achieved within a certain adjustable range. The robot control cabinet 33 receives the in-place information of the main board splice 7 of the combustible gas detector from the main controller. The robot control cabinet 33 controls the motor 344 to rotate, the robot gripper adjustment screw 341 to rotate, and the movable gripper 343 slides between the two support shafts 342. The movable gripper 343 moves so that the distance between the two jaws 345 adapts to the size of the main board splice 7 of the combustible gas detector. The robot body 32 drives the fixed jaw to move so that the two jaws 345 clamp the main board splice 7 of the combustible gas detector and put the main board splice 7 of the combustible gas detector into the empty space in the aging library through the main controller's instruction. It is preferentially placed inside the aging tooling PCB support seat 423. After all the aging tooling PCB support seats 423 are full, it is then placed inside the ordinary aging tooling 43. When the main board splice 7 of the combustible gas detector is placed inside the aging tooling PCB support seat 423, the pneumatic control component 44 controls the external air pump to supply air, and the controller for changing the air path direction controls the telescopic end of the corresponding cylinder one to push 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 on the front side are detection bins. Subsequently, combustible gas is injected through the combustible gas injection port. The combustible gas is mixed by the fan 64 in the sealed bin to achieve concentration equilibrium. The gas concentration required for calibration and inspection varies according to the products produced and is dynamically configured as required. After the inspection is completed, the turret divider 52 rotates the production line tooling 51 with the combustible gas detector main board splice plate 7 to the next station. Press the unlocking hole 514 of the self-locking buckle to unlock the self-locking buckle 513, remove the combustible gas detector main board splice plate 7, and place the combustible gas detector main board splice plate 7 on the upper ends of the two conveyor belt 82. The width adjustment screw 81 of the adjustable conveyor line adjusts the width between the two conveyor belts 82 to adapt to different sizes of the combustible gas detector main board splice plate 7.
