[0004] After the above-mentioned electric iron workpiece is assembled, it is necessary to detect the air tightness, flow rate and the size of the temperature control sensor to reduce the outflow of unqualified products. Summary of the Invention

[0005] In order to detect the air tightness, pressure and the size of the temperature control sensor of the assembled electric iron workpiece, the present application provides a simulation working condition detection device for an electric iron after assembly.

[0006] The simulation working condition detection device for an electric iron after assembly provided by the present application adopts the following technical solutions:

[0007] A simulation working condition detection device for an electric iron after assembly includes a frame. A power supply is provided on the frame. The power supply is used for plug insertion. An air inlet nozzle and an air outlet nozzle are provided on the frame. The air inlet nozzle is used to connect to a gas supply source. An air inlet channel is opened on the air inlet nozzle. The air inlet channel is used to communicate with the air inlet on the connecting pipe. An air outlet channel is provided on the air outlet nozzle. The air outlet channel is used to communicate with the air outlet on the connecting pipe. A flow sensor and a first pressure sensor are provided on the air outlet nozzle. The flow sensor is used to detect the gas flow rate in the air outlet nozzle. The first pressure sensor is used to detect the air pressure in the air outlet nozzle;

[0008] A through hole is opened on the frame. The through hole is used to align with the temperature control sensor. A laser sensor is horizontally slidably connected on the frame. The laser sensor is located below the through hole and slides close to or away from the through hole. The laser sensor is used to detect the height of the temperature control sensor. A driving member one for driving the laser sensor to move is provided on the frame;

[0009] A thimble is slidably connected to the first driving member. The thimble slides closer to or away from the bottom plate on the frame. The thimble is used to squeeze the temperature control sensor. A second driving member for driving the thimble to move is provided on the first driving member. A second pressure sensor is provided on the thimble. The second pressure sensor is used to detect the pressure of the thimble.

[0010] By adopting the above technical solution, after the electric iron workpiece is assembled, the assembled electric iron workpiece is placed on the frame, so that the air inlet channel is communicated with the air inlet of the connecting pipe, and the air outlet channel is communicated with the air outlet of the connecting pipe. Then the plug is inserted into the power supply. If the wiring in the plug is correct, the power supply is turned on. If the wiring in the plug is incorrect, the power supply cannot be turned on. It can be used to detect whether the wire sequence installation of the plug is accurate.

[0011] After the power supply is turned on, air is introduced into the air inlet channel, and the gas enters the connecting pipe to simulate the situation of steam in the connecting pipe. According to the data displayed by the flow sensor and the first pressure sensor, the airtightness and flow rate of the electric iron workpiece are detected and judged.

[0012] Then control the second driving member to drive the thimble to move closer to the bottom plate on the frame, so that the thimble squeezes the temperature control sensor. According to the pressure value detected by the second pressure sensor, it can be judged whether the temperature control sensor is stuck. Then control the second driving member to drive the thimble to move away from the bottom plate on the frame. Then control the first driving member to drive the laser sensor to move closer to the through hole, so that the laser on the laser sensor passes through the through hole to detect the height of the temperature control sensor. According to the distance between the reference block and the laser sensor at this time, the height difference between the temperature control sensor and the reference block can be obtained according to the corresponding conversion formula, so as to detect the size of the temperature control sensor and judge whether it meets the factory requirements.

[0013] Preferably, a first positioning groove for the connector to be inserted into is formed on the frame. The air inlet channel is communicated with the first positioning groove. When the connector is located in the first positioning groove, the air inlet channel is communicated with the air inlet of the connecting pipe.

[0014] By adopting the above technical solution, the first positioning groove is provided. The inner wall of the first positioning groove abuts against the connector to limit the connector, reducing the situation that the connector moves during the detection process, resulting in the disconnection of the air inlet channel and the connecting pipe and affecting the detection result.

[0015] Preferably, a pressing block is slidably moved up and down on the frame. The pressing block is located above the positioning groove. A third driving member for driving the pressing block to move is further provided on the frame.

[0016] By adopting the above technical solution, a pressing block is provided. After the connector is placed in the first positioning groove, the third driving member is controlled to drive the pressing block to move downward and press the connector, thereby positioning the connector, further reducing the situation of the connector moving during the detection process, and making the detection more convenient and accurate.

[0017] Preferably, a metal sensor is further provided on the frame. The metal sensor is aligned with the snap ring on the connector in the first positioning groove, and the metal sensor is used to sense whether there is a snap ring on the connector.

[0018] By adopting the above technical solution, a metal sensor is provided, which can be used to detect whether the snap ring is correctly installed on the connector. If the snap ring is not installed on the connector or the installation position of the snap ring is incorrect, it can be detected by the metal sensor.

[0019] Preferably, a second positioning groove for the bottom plate to be inserted into is formed on the frame, and the air outlet nozzle extends into the second positioning groove.

[0020] By adopting the above technical solution, the second positioning groove is provided, and the inner wall of the second positioning groove abuts against the bottom plate to limit the bottom plate, reducing the situation that the bottom plate moves during the detection process, resulting in the disconnection of the air outlet channel and the connecting pipe and thus affecting the detection result.

[0021] Preferably, a marking member is slidably connected to the frame. The marking member slides close to or away from the second positioning groove. The marking member is used to contact and mark the bottom plate in the second positioning groove. A fourth driving member for driving the marking member to move is provided on the frame. A controller is provided on the frame. The second pressure sensor sends the pressure value to the controller. The controller receives the pressure value and compares it with the pressure preset value. When the pressure value is not greater than the pressure preset value, the controller controls the fourth driving member to drive the marking member to move close to the second positioning groove.

[0022] By adopting the above technical solution, the marking member and the controller are provided. When the thimble presses the temperature control sensor to detect the pressure, if the temperature control sensor is stuck, the pressure value detected by the second pressure sensor is greater than the pressure preset value, the controller cannot be started, and the marking member cannot make a mark on the electric iron workpiece.

[0023] When the pressure value detected by the second pressure sensor is not greater than the pressure preset value, the setting of the temperature control sensor meets the requirements. The controller controls the fourth driving member to drive the marking member to move close to the second positioning groove, so that the marking member contacts the bottom plate in the second positioning groove and makes a mark on the bottom plate, so as to facilitate the subsequent identification of qualified and unqualified electric iron workpieces and reduce the outflow of unqualified workpieces.

[0024] Preferably, a limiting groove is formed on the frame, and the limiting groove is used for the mounting seat to be inserted. A distance sensor is provided on the frame, and the distance sensor is used to detect the distance between it and the mounting seat in the limiting groove. The distance sensor sends a distance value to the controller, and the controller receives the distance value and compares it with a preset distance value. When the distance value is equal to the preset distance value, the controller controls the power supply to be turned on.

[0025] By adopting the above technical solution, the limiting groove and the distance sensor are provided. If the mounting direction of the mounting seat is incorrect, after the mounting seat is inserted into the limiting groove, the distance sensor detects and sends a distance value to the controller. If the controller detects that the distance value is not equal to the preset distance value, the power supply cannot be turned on, so that the staff can find the problem and take out the defective workpiece, which can be used to detect whether the mounting seat is installed correctly.

[0026] Preferably, a probe is provided on the frame, and the probe is used to abut against the metal sheet on the bottom plate, and a current sensor is connected to the probe.

[0027] By adopting the above technical solution, it can be used to detect whether the circuit in the connecting pipe is conducting. After the power supply is turned on, the probe abuts against the metal sheet on the bottom plate. If the circuit is conducting, the metal sheet is charged, and the current sensor detects the current. If the circuit cannot conduct, the metal sheet is not charged, and the current sensor cannot detect the current.

[0028] Preferably, a pressing plate is slid up and down on the frame. The pressing plate is located above the second positioning groove, and a fifth driving member for driving the pressing plate to move is further provided on the frame.

[0029] By adopting the above technical solution, the pressing plate is provided. After the bottom plate is placed in the second positioning groove, the fifth driving member is controlled to drive the pressing plate to move downwards and press the bottom plate, so as to position the bottom plate, reducing the situation that the bottom plate moves during the process of the ejector pin pressing the convex block.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. After the electric iron workpiece is assembled, plug the plug into the power supply. According to the power connection situation, check whether the wire sequence of the plug is correctly installed. After the power is connected, ventilate the air intake passage. According to the data displayed by the flow sensor and the first pressure sensor, detect and judge the airtightness and flow rate of the electric iron workpiece. Then control the second driving part to drive the thimble to squeeze the temperature control sensor. According to the pressure value detected by the second pressure sensor, it can be judged whether the temperature control sensor is stuck. Then drive the first driving part to move the laser sensor so that the laser on the laser sensor passes through the through hole to detect the height of the temperature control sensor. According to the distance between the reference block and the laser sensor at this time, the height difference between the temperature control sensor and the reference block can be obtained according to the corresponding conversion formula, so as to detect the size of the temperature control sensor and judge whether it meets the factory requirements;

[0032] 3. By setting a metal sensor, it can be used to detect whether a snap ring is correctly installed on the connector;

[0033] 6. By setting a marking part and a controller, when the thimble squeezes the temperature control sensor to detect the pressure, if the temperature control sensor is stuck, the pressure value is greater than the preset pressure value, and the controller cannot be started, and the marking part cannot make a mark on the electric iron workpiece. When the pressure value is not greater than the preset pressure value, the controller controls the fourth driving part to drive the marking part to move, so as to make a mark on the bottom plate, so as to facilitate the subsequent identification of qualified and unqualified electric iron workpieces and reduce the outflow of unqualified workpieces;

[0034] 9. By setting a limit groove and a distance sensor, it can be detected whether the mounting seat is correctly installed according to whether the power supply can be turned on. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] See Figure 1 and Figure 4 , a second positioning groove 531 is formed on the upper end surface of the second fixing block 53 for the bottom plate 1 to be inserted into. An air outlet nozzle 14 is fixed on the frame body 51 (see Figure 2 ), and the air outlet nozzle 14 penetrates through the frame body 51 (see Figure 2 ) and is fixedly connected to the frame body 51 (see Figure 2 ).

[0062] See Figure 5 and Figure 6 , a first driving member 17 is fixed on the frame body 51. The first driving member 17 is located below the table top 511 (see Figure 2 ). A second driving member 18 is slidably connected to the first driving member 17. The first driving member 17 drives the second driving member 18 to horizontally slide close to or away from the through hole 512 (see Figure 4). In this embodiment, the first driving member 17 is an oil cylinder, and the second driving member 18 is a pneumatic cylinder.

[0063] See Figure 6 and Figure 7 , a laser sensor 19 is fixed on the body of the second driving member 18. The laser sensor 19 is horizontally slidably connected to the frame body 51 through the cooperation of the second driving member 18 and the first driving member 17 (see Figure 2 ). The first driving member 17 drives the laser sensor 19 to move through the cooperation with the second driving member 18. The laser sensor 19 is located below the through hole 512 (see Figure 4 ) and slides close to or away from the through hole 512 (see Figure 4 ). When the bottom plate 1 (see Figure 1 ) is located in the second positioning groove 531 (see Figure 4 ), the laser sensor 19 is used to detect the height of the temperature control sensor 12 (see Figure 1 ).

[0064] See Figure 1 and Figure 7 , a thimble 20 is fixed on the piston rod of the second driving member 18. The thimble 20 is located below the through hole 512 (see Figure 4 ). The second driving member 18 drives the thimble 20 to slide close to or away from the bottom plate 1 in the second positioning groove 531 (see Figure 4 ), and the sliding direction of the thimble 20 is vertically arranged.

The thimble 20 is fixedly connected to the piston rod of the second driving member 18 through the second pressure sensor 201. The second pressure sensor 201 is used to detect the pressure of the thimble 20.

[0065] See Figure 2 and Figure 4 , a marking member 21 is also horizontally slidably connected to the frame body 51. The marking member 21 is located on one side of the second positioning groove 531 in the horizontal direction, and the marking member 21 passes through the second fixing block 53 and slides close to or away from the second positioning groove 531. The marking member 21 is used to contact and mark the bottom plate 1 in the second positioning groove 531 (see Figure 1 ). A fourth driving member 22 is fixed on the frame body 51. The piston rod of the fourth driving member 22 is fixedly connected to the marking member 21. The fourth driving member 22 drives the marking member 21 to move. In this embodiment, the marking member 21 is a marker pen, and the fourth driving member 22 is a pneumatic cylinder.

[0066] See Figure 2 and Figure 6, a controller 23 is installed on the frame body 51. The second pressure sensor 201 sends the pressure value to the controller 23. The controller 23 receives the pressure value and compares it with the preset pressure value. When the pressure value is not greater than the preset pressure value, the controller 23 controls the fourth driver to drive the marking member 21 to move closer to the second positioning groove 531 (see Figure 4 ), so that the marking member 21 contacts the bottom plate 1 (see Figure 4 ) in the second positioning groove 531 (see Figure 1 ) and makes a mark on the bottom plate 1 (see Figure 1 ).

[0067] See Figure 2 and Figure 4 , a plurality of probes 24 are also fixed on the frame body 51. The plurality of probes 24 are all located in the second positioning groove 531. When the bottom plate 1 is located in the second positioning groove 531, the probes 24 are used to abut against the metal sheet 13 (see Figure 1 ) on the bottom plate 1 (see Figure 1 ). In actual use, a current sensor is connected to the probe 24.

[0068] In actual use, after the power supply 6 is turned on, by abutting the probe 24 against the metal sheet 13 on the bottom plate 1, it can be used to detect whether the internal circuit of the connecting pipe 2 is conducting. If the circuit is conducting, the metal sheet 13 is charged and the current sensor detects the current. If the circuit cannot conduct, the metal sheet 13 is not charged and the current sensor cannot detect the current.

[0069] See Figure 1 and Figure 3 , a limiting groove 522 is also formed on the first fixing block 52. The limiting groove 522 is located on one side of the first positioning groove 521 in the horizontal direction. The limiting groove 522 is used for the mounting seat 4 to be inserted. A distance sensor 25 is fixed on the first fixing block 52. The distance sensor 25 is located on one side of the limiting groove 522 in the horizontal direction. The distance sensor 25 is aligned with the mounting seat 4 in the limiting groove 522. The distance sensor 25 is used to detect the distance between it and the mounting seat 4 in the limiting groove 522. The distance sensor 25 sends the distance value to the controller 23 (see Figure 2 ), and the controller 23 (see Figure 2 ) receives the distance value and compares it with the preset distance value. When the distance value is equal to the preset distance value, the controller 23 (see Figure 2 ) controls the power supply 6 (see Figure 2 ) to be turned on.

[0070] The mounting base 4 has a certain shape with an uneven surface. Therefore, the distances from different positions on the surface of the mounting base 4 to the distance sensor 25 are inconsistent. In actual use, if the mounting base 4 is installed in the wrong direction, after the mounting base 4 is snapped into the limiting groove 522, the distance sensor 25 detects and sends a distance value to the controller 23. If the controller 23 detects that the distance value is not equal to the preset distance value, the power supply 6 cannot be turned on. If the mounting base 4 is installed correctly, the distance value is equal to the preset distance value, and the controller 23 controls the power supply 6 to turn on, which can be used to detect whether the mounting base 4 is installed correctly.

[0071] The implementation principle of Embodiment 1 is as follows:

[0072] After the electric iron workpiece is assembled, snap the connector 41 into the first positioning groove 521 and the bottom plate 1 into the second positioning groove 531. At this time, the reference block 11 abuts against the inner wall of the bottom of the second positioning groove 531 to limit the bottom plate 1, so that the air inlet channel 71 is communicated with the air inlet of the connecting pipe 2, and the air outlet channel 141 is communicated with the air outlet of the connecting pipe 2. Control the third driving member 10 to drive the pressing block 9 to move downward and press tightly against the connector 41 in the first positioning groove 521, and control the fifth driving member 514 to drive the pressing plate 513 to move downward to press tightly against the bottom plate 1 in the second positioning groove 531.

[0073] Then plug the plug 42 into the power supply 6. If the wiring in the plug 42 is correct, the power supply 6 is connected. If the wiring in the plug 42 is incorrect, the power supply 6 cannot be connected, which can be used to detect whether the wire sequence installation of the plug 42 is accurate.

[0074] After the power supply 6 is connected, ventilate the air inlet channel 71, and the gas enters the connecting pipe 2 to simulate the situation of steam in the connecting pipe 2. According to the data displayed by the flow sensor 15 and the first pressure sensor 16, the airtightness and flow rate of the electric iron workpiece are detected and judged.

[0075] Then control the second driving member 18 to drive the ejector pin 20 to move closer to the bottom plate 1 on the frame 5, so that the ejector pin 20 presses the temperature control sensor 12. According to the pressure value detected by the second pressure sensor 201, it can be judged whether the temperature control sensor 12 is stuck.

[0076] Then, control the second driving member 18 to drive the ejector pin 20 to move away from the bottom plate 1 on the frame 5. Next, control the first driving member 17 to drive the second driving member 18 to drive the laser sensor 19 to move closer to the through hole 512, so that the laser on the laser sensor 19 passes through the through hole 512 to detect the height where the temperature control sensor 12 is located. Since the height between the reference block 11 and the laser sensor 19 remains unchanged, according to the height between the reference block 11 and the laser sensor 19 at this time, the height difference between the temperature control sensor 12 and the reference block 11 can be obtained according to the corresponding conversion formula. The conversion formula is the height detected by the laser sensor 19 minus the height between the reference block 11 and the laser sensor 19, that is, the height difference between the temperature control sensor 12 and the reference block 11, so as to detect the size of the temperature control sensor 12 and determine whether it meets the factory requirements.

[0077] Embodiment 2

[0078] The difference from Embodiment 1 is as follows. Refer to Figure 8 and Figure 9 , a fixed column 26 is fixed on the frame body 51. The fixed column 26 is located between the first fixed block 52 and the second fixed block 53 and is located outside the tabletop 511. Two through holes 261 are formed in the fixed column 26. Both of the two through holes 261 vertically penetrate the fixed column 26 and are arranged at intervals. Two sliding rods 27 are slidably moved up and down on the fixed column 26. The positions of the two sliding rods 27 correspond to the two through holes 261 one by one. Each sliding rod 27 is slidably moved up and down in the corresponding through hole 261.

[0079] Refer to Figure 9 and Figure 10 , a plurality of card slots 271 are formed on the end faces of the two sliding rods 27 close to each other. The plurality of card slots 271 on the same sliding rod 27 are evenly spaced along the vertical direction. A clamping block 28 is fixed on the inner wall of each through hole 261. The card slot 271 is for the clamping block 28 to be inserted. A pressing spring 32 is fixed on the inner wall of each through hole 261. The pressing spring 32 is located on the side of the sliding rod 27 away from the card slot 271 and abuts against the sliding rod 27, so that the clamping block 28 is inserted into the card slot 271 and abuts against the bottom inner wall of the card slot 271.

[0080] Refer to Figure 9 and Figure 10 , a limiting plate 29 is also hinged on the fixed column 26. The number and position of the limiting plates 29 correspond to the number and position of the sliding rods 27 one by one. The limiting plate 29 is located on the side of the corresponding sliding rod 27 away from the card slot 271 and above the fixed column 26. The hinge axis of the limiting plate 29 is vertically arranged. When the limiting plate 29 faces the corresponding sliding rod 27, the distance between the limiting plate 29 and the corresponding sliding rod 27 is less than the depth of the card slot 271.

[0081] Refer to Figure 1 and Figure 9, a pipe winding column 30 is also slidably connected to the frame body 51. The pipe winding column 30 is located directly below the fixed column 26 and moves up and down and slides on the frame body 51. Both the pipe winding column 30 and the fixed column 26 are used for connecting the winding of the pipe 2. A compression spring 31 is also fixed on the frame body 51. The compression spring 31 is located on the side of the pipe winding column 30 away from the fixed column 26 and abuts against the fixed column 26, so that the pipe winding column 30 has a tendency to approach the fixed column 26.

[0082] The implementation principle of Embodiment 2 is as follows:

[0083] When the length of the connecting pipe 2 is relatively long, the connecting pipe 2 can be wound around the pipe winding column 30, and then the pipe winding column 30 is released. Under the action of the compression spring 31, the pipe winding column 30 moves closer to the fixed column 26, so that the fixed column 26 abuts against the connecting pipe 2 wound on the pipe winding column 30. Through the friction force between the fixed column 26 and the connecting pipe 2, the sliding of the connecting pipe 2 on the pipe winding column 30 is reduced, and the two sliding rods 27 are located on the opposite sides of the connecting pipe 2 wound on the pipe winding column 30 to limit the connecting pipe 2, preventing the connecting pipe 2 from slipping off the pipe winding column 30, and reducing the situation that the connecting pipe 2 is too long and is easily tripped by the staff or damaged when dragged to the ground during the detection process.

[0084] When there is still part of the connecting pipe 2 dragged to the ground after the connecting pipe 2 is wound around the fixed column 26, the connecting pipe 2 can be continuously wound around the fixed column 26, and then the sliding rod 27 is moved in the direction away from the block 28, so that the block 28 is disengaged from the card slot 271. Then the sliding rod 27 is moved in the direction close to the pipe winding column 30, so that the length of the part of the sliding rod 27 extending out of the fixed column 26 becomes larger, so that when the connecting pipe 2 wound on the fixed column 26 abuts against the connecting pipe 2 wound on the pipe winding column 30 later, the sliding rod 27 can still limit the connecting pipe 2 wound on the pipe winding column 30.

[0085] Until the block 28 is aligned with one of the card slots 271, the sliding rod 27 moves closer to the block 28 under the action of the corresponding abutting spring 32, so that the block 28 is snapped into the corresponding card slot 271 to position the sliding rod 27. The limiting plate 29 is flipped so that the limiting plate 29 faces the sliding rod 27. At this time, when there are more connecting pipes 2 wound on the fixed column 26, the connecting pipe 2 pushes the sliding rod 27 to move in the direction away from the block 28 to accommodate more connecting pipes 2, improving the applicability of the fixed column 26, and the limiting plate 29 abuts against the sliding rod 27, thereby limiting the upper limit of the connecting pipes 2 that can be wound on the fixed column 26 and preventing the block 28 from disengaging from the card slot 271.

[0086] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
