[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments of this disclosure to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0029] In the description of this utility model, it should be noted that the term "comprising" and its variations indicate an open-ended inclusion, i.e., "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "and / or" when used to list two or more items means that it may include any one of the listed items, or any combination of two or more of the listed items. Furthermore, in the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] This utility model provides a device for detecting metal clips on vehicle interior panels, referenced. Figures 2-6As shown, the device includes a support device, a stamping device, and a control device disposed on the detection box 2. The support device includes multiple support members for supporting the interior panel 1. The stamping device includes a drive device and a lifting mechanism 4, wherein the drive device drives the lifting mechanism 4 to move up and down. The control device includes a first sensor 51, a delay module 52, and a first relay 53. Multiple first sensors 51 are configured, and their number and arrangement are adapted to the number and arrangement of metal buckles 11, for detecting the presence of metal buckles 11. Each first sensor 51 and the delay module 52 are connected in series to form a signal controller. The first relay 53 includes a coil input terminal A1, a coil output terminal B1, NO1 and NC1 contacts connected to a common terminal COM1, and NO2 and NC2 contacts connected to a common terminal COM2. The NC1 contact is connected to the NO2 contact, and the NC2 contact is connected to the NO1 contact. The coil input terminal A1 is connected to the output terminal of the signal controller, and the coil output terminal B1 is used to connect to the negative terminal of the power supply. The NO1 and NO2 contacts are used to connect to the positive and negative terminals of the power supply, respectively. The common terminal COM1 and the common terminal COM2 are respectively connected to two terminals of the driving device.

[0031] Interior panel 1 is placed on various support members. When the first sensor 51 detects the metal clip 11, the first sensor 51 outputs a high-level signal to power the next electronic component. When any first sensor 51 fails to detect the metal clip 11, it outputs a low-level signal, and the circuit is disconnected. When all first sensors 51 detect the metal clip 11, the metal clip 11 of the interior panel 1 is not missing, and the test is qualified. At this time, the delay module 52 is powered on, and the signal controller formed by the series connection of each first sensor 51 and the delay module 52 outputs a high-level signal. The coil of the first relay 53 is powered on, the common terminal COM1 is connected to the NO1 contact, and the common terminal COM2 is connected to the NO2 contact, so that the drive device is connected to the power supply in the forward direction. The drive device drives the lifting mechanism 4 to move upward, stamping the qualified interior panel 1 with a mark. The delay module 52 is preset with a delay time t. When the stamping is completed, the delay module 52 is disconnected after the power-on time reaches the delay time t. The coil of the first relay 53 is de-energized, the common terminal COM1 is connected to the NC1 contact, and the common terminal COM2 is connected to the NC2 contact, so that the drive device is connected to the power supply in reverse. The drive device drives the lifting mechanism 4 to move downward to reset, thereby realizing the fully automatic control of the stamping process.

[0032] Each first sensor 51 and delay module 52 are connected in series. The delay module 52 can be placed before all the first sensors 51, between two first sensors 51, or after all the first sensors 51. The output terminal of the first sensor 51 or the delay module 52 connected to the coil input terminal A1 is the output terminal of the signal controller. For example, refer to Figure 5 and Figure 6 As shown, the interior panel 1 has four metal clips 11. Correspondingly, the detection device is equipped with four first sensors S1, S2, S3, and S4. The first sensors S1 to S4 are connected in series. The positive pin of the first sensor S1 is connected to the positive terminal of the power supply. The positive pin of the next sensor S1 is connected to the output pin of the previous sensor S1. The output pin of the last sensor S4 is connected to the positive pin of the delay module 52. The coil input terminal A1 is connected to the output terminal of the delay module 52. The negative pins of each first sensor S1 and the negative pin of the delay module 52 are connected to the negative terminal of the power supply. In this way, each first sensor S1 and the delay module 52 are connected in series, and the power supply of the next electronic component is provided by the previous electronic component. The wiring is convenient and can effectively prevent missed detections. Preferably, the first sensor 51 is set as an inductive proximity sensor. For example, the first sensor 51 can be a Pepperl+Fuchs NBN4-12GM50-E0 type DC three-wire NPN normally open proximity switch with a sensing distance of about 4mm, which can accurately detect whether the metal buckle 11 is present.

[0033] Preferably, the driving device uses an electric actuator 3 with a limit function or a linear motor. For example, a Bolin STA-50-24 electric actuator 3 can be used, which is fixed to the detection box 2 by a first L-shaped bracket 31. The first side of the first L-shaped bracket 31 is fixed to the detection box 2 by screwing or welding, and a mounting hole is provided on the second side of the first L-shaped bracket 31. After passing a bolt through the assembly hole at the tail end of the electric actuator 3 and the mounting hole of the first L-shaped bracket 31, it can be tightened with a nut. By connecting the two terminals of the electric actuator 3 to the common terminal COM1 and the common terminal COM2 respectively, the extension or retraction of the actuator body 32 of the electric actuator 3 can be controlled by the first relay 53. The electric actuator 3 is equipped with an extension limit switch and a reset limit switch. When the motor of the electric actuator 3 rotates in the forward direction and drives the actuator body 32 to extend to the extension limit switch, the motor automatically cuts off the power and stops running; when the motor of the electric actuator 3 rotates in the reverse direction and drives the actuator body 32 to retract to the reset limit switch, the motor automatically cuts off the power and stops running. In this way, the electric push rod 3 can control the motor to stop, and the forward and reverse movements of the electric push rod 3 can be controlled by a first relay 53 and a delay module 52, so as to realize the automatic stamping and reset of the lifting mechanism 4. Compared with using a controller (control chip, microcontroller, etc.) to control the operation of the drive device, the control is simple and the cost is low.

[0034] Preferably, the first relay 53 can be a double-pole double-throw relay, for example, a Schneider 8-pin relay RXM2LB2BD. The delay module 52 can be a Bestep-JK02-24V, which is low-cost and easy to wire. The delay time t can be set to 5-10 seconds according to the pushing speed of the electric push rod 3 to ensure sufficient pressing time for the stamping device and clear stamping. Of course, the driving device can also be a delay linear motor or a delay electric push rod 3 with a delay function.

[0035] Each electronic component is powered by a power supply. The detection box 2 is equipped with a power interface. The detection device can be powered by a battery, with the power interface correspondingly configured as the positive and negative terminals of the battery. Alternatively, the detection device can be powered by AC power, with the power interface also configured as an AC power interface. When AC power is connected, the switching power supply 6 converts the 220V AC power to a suitable voltage to power each electronic component. For example, a Mean Well NDR-120-24 switching power supply 6 can be used to convert the 220V AC power to 24V to power each of the electronic components, such as the first sensor 51, the second sensor 58, the delay module 52, the drive device, and the indicator device. All electronic components have the same voltage. For example, the rated voltage of each electronic component is 24V. When the power interface is connected, it powers the first sensor 51. When the first sensor 51 detects the presence of the metal latch 11, its output pin outputs 24V to power the next first sensor 51, and so on, until the coil of the first relay 53 is powered. When the current first sensor 51 cannot detect a signal, it outputs a low level, and the next first sensor 51 is powered off.

[0036] In some embodiments, reference Figure 5 and Figure 6 As shown, the testing equipment also includes an indicating device, which includes a pass light 54 connected in parallel to the coil of the first relay 53. Specifically, the pass light 54 is connected to the output terminal of the delay module 52, with one end connected to the coil input terminal A1 and the other end connected to the coil output terminal B1 (connected to the negative terminal of the power supply). When the delay module 52 outputs a high-level signal, the pass light 54 is powered on and illuminates, indicating that all the first sensors 51 have detected the metal clips 11 and that no metal clips 11 are missing. Of course, the pass light 54 can also be connected in series to the driving device. Preferably, the pass light 54 can be a green light; when the green light is on, it indicates that the interior panel 1 has passed the test.

[0037] In some embodiments, such as Figure 6 As shown, the indicating device further includes a second relay 55 and an alarm; the second relay 55 includes a coil input terminal A2, a coil output terminal B2, a NO3 contact and an NC3 contact connected to a common terminal COM3; each of the first sensors 51 is connected in series, the output pin of the last first sensor 51 is connected to the coil input terminal A2, the coil output terminal B2 is used to connect to the negative terminal of the power supply, the common terminal COM3 is used to connect to the positive terminal of the power supply, the positive pin of the delay module 52 is connected to the NO3 contact, and the coil input terminal A1 is connected to the output terminal of the delay module 52; the alarm is connected between the NC3 contact of the second relay 55 and the negative terminal of the power supply.

[0038] When all the first sensors 51 detect the metal clip 11, the last first sensor 51 outputs a high level, energizing the coil of the second relay 55. The common terminal COM3 connects to the NO3 contact, and the delay module 52 and the coil of the first relay 53 are powered on, thereby controlling the drive device to stamp the interior panel 1. When the metal clip 11 is missing, the corresponding first sensor 51 outputs a low level, de-energizing the electronic components between the first sensor 51 and the second relay 55. The coil of the second relay 55 is de-energized, and the common terminal COM3 connects to the NC3 contact. The alarm is powered on, providing an alarm reminder for the detection result of the missing metal clip 11. The second relay 55 can be a 5-pin single-pole double-throw relay, for example, a Schneider 5-pin relay RPM12BD. Of course, the first relay 53 and the second relay 55 can also use relays with more pins, for example, a Schneider 14-pin relay RXM4AB2BD or an Omron MY4N-J DC24 intermediate relay. The warning device includes a warning light 56 ​​and / or a buzzer 57. The warning light 56 ​​can be a red light, and the buzzer 57 can be set separately. In this case, when both the warning light 56 ​​and the buzzer 57 are included, the warning light 56 ​​and the buzzer 57 can be connected in series or in parallel, or a red light with an integrated buzzer 57 can be selected. If the metal clip 11 is lost, the red light and the buzzer 57 will sound an alarm to remind the operator to replace the metal clip 11.

[0039] In some embodiments, such as Figure 6 As shown, the indicating device also includes a second sensor 58 for detecting the presence of the interior panel 1. The second sensor 58 is connected in series with the warning device. Specifically, the second sensor 58 can be located between the NC3 contact and the warning device, or between the warning device and the negative power supply. For example, the positive pin of the second sensor 58 is connected to the NC3 contact, and its negative pin is connected to the negative power supply. The warning light 56 ​​and / or buzzer 57 are connected to the output pin of the second sensor 58. When the interior panel 1 is placed, if the first sensor 51 detects that the metal clip 11 is missing, the common terminal COM3 connects to the NC3 contact, the second sensor 58 is powered on, detects the interior panel 1, outputs a high-level signal, the warning device is powered on, and the warning device emits an alarm signal. When the interior panel 1 is not placed, none of the first sensors 51 detect the metal clip 11. The common terminal COM3 remains connected to the NC3 contact, the second sensor 58 is powered on, but it does not detect the interior panel 1, outputs a low-level signal, the warning device is de-powered, and the warning device does not operate. In this way, when the interior panel 1 is not placed, the alarm can be prevented from continuously sounding.

[0040] Preferably, the second sensor 58 is configured as a photoelectric sensor or a capacitive proximity sensor, etc. For example, the second sensor 58 can be a Heng Hui HH18L-30DN1 type DC three-wire NPN normally open photoelectric sensor with a sensing distance of 30mm, which can detect the presence of non-metallic interior panel 1. The second sensor 58 can be fixed by a second L-shaped bracket 581. The first side of the second L-shaped bracket 581 is fixed to the detection box 2 by screwing or welding. A mounting hole is provided on the second side of the second L-shaped bracket 581. With the sensing head of the second sensor 58 facing upward, the two threaded knobs are respectively pressed against the two sides of the second side, thereby fixing the second sensor 58 to the second L-shaped bracket 581. The mounting hole can be configured as a first elongated hole extending in the vertical direction to facilitate adjustment of the height of the second sensor 58. The second sensor 58 and the first sensor 51 are staggered. Each first sensor 51 is set at the position of the corresponding metal buckle 11, and the second sensor 58 is set in the middle of the interior panel 1 corresponding to other areas.

[0041] In some embodiments, such as Figure 3 As shown, the lifting mechanism 4 includes a bracket 41, a guide column 42, and a stinger 43. The guide column 42 is disposed on the detection box 2 and extends vertically. The bracket 41 is provided with a guide hole 411, which is clearance-fitted onto the guide column 42. The stinger 43 is disposed on the top of the bracket 41. The bracket 41 is connected to the output end of the driving device via a connecting rod 44. The first end of the connecting rod 44 is rotatably connected to the bracket 41, and the second end is rotatably connected to the output end of the driving device. The output end of the driving device moves horizontally.

[0042] When the interior panel 1 is placed on each support, and each first sensor 51 detects the metal clip 11, indicating that the metal clip 11 of the interior panel 1 is not missing and the inspection is qualified, the electric push rod 3 starts running and extends forward in the horizontal direction, driving the second end of the connecting rod 44 to move forward. Since the first end of the connecting rod 44 is rotatably connected to the bracket 41, and the bracket 41 is restricted by the guide post 42, it can only move in the vertical direction along the guide post 42, making it impossible for the first end of the connecting rod 44 to move in the horizontal direction. Therefore, the connecting rod 44 rotates upward around the second end, pushing the bracket 41 and the stamp head 43 to move upward as a whole, stamping and marking the position of the sound insulation cotton on the interior panel 1. In this way, the horizontal movement of the drive device can be converted into the vertical movement of the stamp head 43 through the connecting rod 44, stamping and marking the inner surface of the interior panel 1. This can mark the plate-like structure of the interior panel 1, and at the same time, it is convenient to arrange the various components of the stamping device in the detection box 2.

[0043] Preferably, the punch head 43 can be detachably connected to the bracket 41 via a bolt-nut assembly for easy replacement. A second elongated hole extending vertically is provided on the punch head 43, and through holes penetrating opposite sides of the bracket 41 are provided on the bracket 41. The punch head 43 is fixed to the bracket 41 by tightening the bolt through the through holes and the second elongated hole with a nut. The height of the punch head 43 can also be adjusted by adjusting the height of the bolt passing through the second elongated hole, allowing the punch head 43 to press against the inner surface of the interior trim panel 1. The stroke of the electric push rod 3 can also be adjusted according to the upward movement distance of the punch head 43, or an electric push rod 3 with a suitable stroke can be directly selected.

[0044] Preferably, the connecting rod 44 comprises two rods, the first ends of which are rotatably connected to opposite sides of the bracket 41. The output end of the drive device is horizontally provided with an output rod 45 perpendicular to its direction of movement. The second ends of the two connecting rods 44 are rotatably connected to the two ends of the output rod 45, providing more stable support for the bracket 41 and ensuring smooth vertical movement of the bracket 41. Preferably, the guide posts 42 can also be two, respectively located on the other two sides of the bracket 41, preventing the bracket 41 from rotating around the guide posts 42 and simultaneously stabilizing the vertical movement path of the bracket 41.

[0045] In some embodiments, combined with Figures 2-4 As shown, the detection box 2 includes a box body 21 and a top cover 22. An opening is provided on the top of the box body 21, and the top cover 22 covers the opening. Various support members are disposed on the top cover 22. The top cover 22 has through holes corresponding to the respective first sensors 51, second sensors 58, pass lights 54, warning devices, and stamps 43. The second sensors 58 face their respective through holes, and the first sensors 51, pass lights 54, warning devices, and stamps 43 extend out of their respective through holes. Fixing the various electronic components, such as the first sensors 51, second sensors 58, first relays 53, driving devices, and indicating devices, to the box body 21, and placing the wires between these electronic components inside the box body 21 below the top cover 22, makes the entire detection equipment neat and aesthetically pleasing, while also effectively protecting the electronic components and extending their service life. The through hole corresponding to the first sensor 51 is set as a threaded hole, and the first sensor 51 is threadedly connected and fixed to the top cover 22. By adjusting the length of each first sensor 51 extending out of the through hole, the distance between each first sensor 51 and the corresponding metal buckle 11 can be adjusted, so that the detection result of the first sensor 51 is accurate and reliable. According to the shape of the interior panel 1, the height of each support and the height of each first sensor 51 can be set so that when the interior panel 1 is placed on the support, each first sensor 51 can detect the corresponding metal buckle 11 while maintaining a gap between itself and the metal buckle 11, preventing the first sensor 51 from directly contacting the metal buckle 11 and causing wear.

[0046] In some embodiments, such as Figure 2 As shown, the support components include support platforms 23 and support columns respectively disposed at both ends of the top cover 22. The support platforms 23 are provided with horizontally extending receiving holes 231 for inserting positioning buckles 12 at one end of the interior panel 1; the support columns are used for inserting into the interface at the other end of the interior panel 1. Specifically, each support component can be configured according to the structure of the interior panel 1. For example, two support platforms 23 can be disposed at one end of the top cover 22, with receiving holes 231 provided on the support platforms 23. It is preferable that the receiving holes 231 be through holes, allowing the two positioning buckles 12 at one end of the interior panel 1 to be inserted into the two receiving holes 231 respectively. A first support column 24 and a second support column 25 are disposed at the other end of the top cover 22. The first support column 24 is a conical head, corresponding to the circular interface 13 of the interior panel 1, with the top of the conical head passing through the circular interface 13, allowing the interior panel 1 to be secured to the cylindrical portion. The second support column 25 is a cylindrical head, corresponding to a square interface 14 of the interior panel 1, and is supported at the square interface 14. The interior panel 1 is supported by two receiving holes 231 and two support columns, which can fix the interior panel 1 and limit the length, width and height of the interior panel 1, thereby accurately positioning the interior panel 1, so that each metal buckle 11 corresponds to each first sensor 51, preventing misalignment, and preventing the stamping head 43 from pushing the interior panel 1 when stamping.

[0047] To facilitate moving the testing equipment, two handles 211 can be provided on the box body 21, with the two handles 211 respectively located at opposite ends of the box body 21.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
