[0050] Refer to Figures 1 to 3 as shown in Figure 1 which is a schematic structural diagram of the metal part side hole plugging detection device provided by the embodiment of the present application, Figure 2 and which is a schematic structural diagram of the substrate of the metal part side hole plugging detection device provided by the embodiment of the present application. Figure 3This is a schematic structural diagram of a partial structure of the metal part side hole plugging detection device provided by the embodiment of the present application. This embodiment discloses a metal part side hole plugging detection device, which includes a support table 1, a substrate 2, an insulating bottom plate 3, a detection component 4 and a controller 5. The support table 1 includes a main body part 11, a first support part 12 and a second support part 13. The first support part 12 and the second support part 13 are respectively connected to the main body part 11 and are arranged at intervals along the height direction of the main body part 11. Through the first support part 12 and the second support part 13, each component is arranged in a stacked manner, reducing the installation space of the metal part side hole plugging detection device and improving the space utilization rate.

[0051] The substrate 2 is arranged on the first support part 12, and the substrate 2 is provided with a detection position 21, and the detection position 21 is provided with a limiting groove 22. The length direction of the substrate 2 is Figure 2 the X direction in Figure 2 the Y direction in Figure 2 the Z direction in.

[0052] The insulating bottom plate 3 is arranged in the limiting groove 22. The insulating bottom plate 3 is used to place the metal part to be measured, and the limiting groove 22 is used to limit the insulating bottom plate 3 to reduce the situation of the insulating bottom plate 3 shifting, so as to ensure the accuracy and reliability of the positioning of the metal part to be measured.

[0053] The detection component 4 includes a conductive positioning block 41 and a conductive probe 42. The conductive positioning block 41 and the conductive probe 42 are respectively arranged on the substrate 2. The conductive positioning block 41 is used to limit the metal part to be measured on the insulating bottom plate 3 to reduce the situation of the metal part to be measured shifting. During the detection process, the conductive positioning block 41 is to be in contact with the metal part to be measured. The conductive probe 42 is used to contact the target side hole of the metal part to be measured.

[0054] The controller 5 includes a first input terminal. The controller 5 can judge whether the target side hole is blocked according to the received electrical signal. In this embodiment, the controller 5 adopts a PLC controller (Programmable Logic Controller), and there are two connection methods for the specific detection circuit (not marked in the attached drawings):

[0055] 1) The first input terminal of the controller 5 is electrically connected to the conductive positioning block 41, the conductive probe 42 is electrically connected to the first electrode of the power supply 9, and the common terminal (COM terminal) of the controller 5 is connected to the second electrode of the power supply 9;

[0056] 2) The first input terminal of the controller 5 is electrically connected to the conductive probe 42, the conductive positioning block 41 is electrically connected to the first electrode of the power supply 9, and the common terminal (COM terminal) of the controller 5 is connected to the second electrode of the power supply 9.

[0057] The detection principle is as follows:

[0058] When there is no glue blockage at the target side hole position, the conductive probe 42 contacts the target side hole position, making the first input terminal of the controller 5 conduct with the first electrode of the power supply 9; and the common terminal (COM terminal) of the controller 5 itself conducts with the second electrode of the power supply 9; in this way, the controller 5 can detect that its first input terminal conducts with the common terminal (COM terminal), and then determines that the target side hole is not blocked;

[0059] When there is glue blockage at the target side hole position, the conductive probe 42 contacts the target side hole position, and the glue blockage makes the first input terminal of the controller 5 unable to conduct with the first electrode of the power supply 9; and the common terminal (COM terminal) of the controller 5 itself conducts with the second electrode of the power supply 9; in this way, the controller 5 cannot detect that its first input terminal conducts with the common terminal (COM terminal), and then determines that the target side hole is blocked.

[0060] In practical applications, the first electrode can be the positive electrode of the power supply 9, and at this time the second electrode is the negative electrode of the power supply 9; or, the first electrode can also be the negative electrode of the power supply 9, and at this time the second electrode is the positive electrode of the power supply 9.

[0061] In other embodiments, the controller 5 can also use a single-chip microcomputer with a potential detection function, and there are also two connection methods for the specific detection circuit:

[0062] 1) The first input terminal of the controller 5 is electrically connected to the conductive positioning block 41, and the conductive probe 42 is electrically connected to the first electrode of the power supply 9;

[0063] 2) The first input terminal of the controller 5 is electrically connected to the conductive probe 42, and the conductive positioning block 41 is electrically connected to the first electrode of the power supply 9.

[0064] The detection principle is as follows:

[0065] When there is no glue blockage at the target side hole position, the conductive probe 42 contacts the target side hole position, making the first input terminal of the controller 5 receive the level signal conducted by the first electrode of the power supply 9. This level signal may be a high level or a low level. Based on this level signal, it can be determined that the target side hole is not blocked;

[0066] When there is glue blockage at the target side hole position, the conductive probe 42 contacts the target side hole position, and the glue blockage makes the first input terminal of the controller 5 unable to conduct with the first electrode of the power supply 9; in this way, no level signal is input to the first input terminal, and the controller 5 determines that the target side hole is blocked based on this.

[0067] In this embodiment, there are four detection components 4, and the positions of the respective detection components 4 correspond to the positions of the respective target side holes of the metal part to be measured, so as to achieve one-time detection of multiple positions, further improving the working efficiency. It can be understood that in other embodiments, the number of detection components 4 can be set corresponding to the number of target side holes of the metal part to be measured.

[0068] In this embodiment, there are two detection positions 21, and the two detection positions 21 are spaced apart along the length direction of the substrate 2. Through double-station operation, the working efficiency is improved. It can be understood that in other embodiments, there can also be three or more detection positions 21.

[0069] In this embodiment, along the height direction of the substrate 2, the upper surface of the insulating bottom plate 3 is higher than the upper surface of the substrate 2 to ensure that the metal part to be measured is separated from the substrate 2, so that the metal part to be measured and the conductive probe 42 form a unique circuit loop. Specifically, the upper surface of the insulating bottom plate 3 is 0.5 mm higher than the upper surface of the substrate 2 to prevent the insulating bottom plate 3 from being too high and affecting the layout of other components.

[0070] In this embodiment, the conductive probe 42 is made of copper. Copper has good electrical conductivity and is relatively light in weight, ensuring the reliability of detection and facilitating the installation of the conductive probe 42. It can be understood that in other embodiments, the conductive probe 42 can also be made of other materials, such as aluminum or graphene, etc.

[0071] The conductive positioning block 41 of this embodiment is used to limit the metal part to be measured on the insulating bottom plate 3, and the conductive probe 42 is used to contact the target side hole of the metal part to be measured. The controller 5 includes a first input terminal, and the first input terminal is electrically connected to the conductive positioning block 41. The conductive probe 42 is electrically connected to the first electrode of the power supply 9. Or, the first input terminal is electrically connected to the conductive probe 42, and the conductive positioning block 41 is electrically connected to the first electrode. Since the colloid at the position of the blocked hole is non-conductive, when a blocked hole occurs, the conductive positioning block 41 and the conductive probe 42 cannot be electrically connected, and the controller 5 will not receive an electrical signal. When no blocked hole occurs, the controller 5 can receive an electrical signal. Therefore, the controller 5 can efficiently and accurately determine whether the side hole of the metal part is blocked according to whether it receives an electrical signal, thereby ensuring the product quality, reducing the cost, and improving the working efficiency.

[0072] Refer to Figures 2 to 5 as shown in Figure 4 is Figure 3 the partial enlarged view of A in Figure 5 is the exploded view of a part of the metal part side hole blockage detection device provided by the embodiment of the present application. The substrate 2 is provided with a substrate probe hole 23, and the insulating bottom plate 3 is provided with a bottom plate probe hole 31 above the substrate probe hole 23. The conductive probe 42 is inserted through the substrate probe hole 23 and the bottom plate probe hole 31.

[0073] The detection component 4 further includes a probe driving member 43, a probe fixing block 44 and a fastener. The probe driving member 43 is disposed on the side of the substrate 2 facing away from the insulating base plate 3. The probe fixing block 44 is connected to the probe driving member 43. The conductive probe 42 is connected to the probe fixing block 44 through the fastener. Among them, the fastener can be a bolt or a pin, etc. Specifically, the conductive probe 42 includes a bottom plate abutting portion 421. A first connection hole is provided at the bottom of the bottom plate abutting portion 421. The probe fixing block 44 is provided with a second connection hole. The fastener passes through the first connection hole and the second connection hole respectively, so that the conductive probe 42 is connected to the probe fixing block 44, and a protruding portion 420 protrudes from the bottom plate abutting portion 421 toward the target side hole. The protruding portion 420 is used to abut against the target side hole under the drive of the probe driving member 43. By driving the conductive probe 42 to move through the probe driving member 43, the automation of detection is realized, the labor cost is reduced, and the work efficiency is improved.

[0074] In this embodiment, the side wall of the bottom plate probe hole 31 on the side close to the target side hole is located directly above the substrate probe hole 23, so that the vertical distance between the side wall of the bottom plate probe hole 31 on the side close to the target side hole and the target side hole is greater than the vertical distance between the side wall of the substrate probe hole 23 on the side close to the target side hole and the target side hole, thereby ensuring that the conductive probe 42 will not contact the substrate 2 when moving in the direction close to the target side hole, reducing the situation where the conductive probe 42 is conductively connected to the substrate 2, and thus ensuring the accuracy and reliability of the detection by the conductive probe 42.

[0075] In this embodiment, the probe driving member 43 is used to drive the conductive probe 42 to abut against and away from the target side hole. It can be understood that in other embodiments, the probe driving member 43 can also be only used to drive the conductive probe 42 to abut against the target side hole, or the probe driving member 43 can also be only used to drive the conductive probe 42 to move away from the target side hole.

[0076] Refer to Figure 2 、 Figure 3 and Figure 6 as shown, Figure 6 which is a schematic structural diagram of another perspective of a partial structure of the metal part side hole plugging detection device provided by the embodiment of the present application. The substrate 2 is further provided with a through groove 24. The metal part side hole plugging detection device further includes a limit driving assembly 6. The limit driving assembly 6 includes a limit driving member 61 and a limit member 62. The limit driving member 61 is disposed on the side of the substrate 2 facing away from the insulating base plate 3. The limit member 62 is connected to the limit driving member 61 and passes through the through groove 24, and the limit member 62 and the conductive positioning block 41 are respectively disposed on the left and right sides of the insulating base plate 3 to limit the width of the metal part to be measured. The limit driving member 61 is used to drive the limit member 62 to move along the length direction of the substrate 2, so that the limit member 62 pushes the metal part to be measured to abut against the conductive positioning block 41, so that the metal part to be measured is electrically connected to the conductive positioning block 41.

[0077] In this embodiment, the conductive positioning block 41 is fixedly connected to the substrate 2, and the limiting member 62 can move along the length direction of the substrate 2. By only driving the limiting member 62 located on one side of the insulating base plate 3 to move, the stability when pushing the metal part to be measured is ensured. It can be understood that in other embodiments, the conductive positioning block 41 and the limiting member 62 can also move along the length direction of the substrate 2 respectively.

[0078] In this embodiment, limiting members 62 and conductive positioning blocks 41 are respectively arranged at the upper and lower ends of the substrate 2, so as to limit the metal part to be measured in the length direction, further reducing the situation of the metal part to be measured shifting, and ensuring the accuracy and reliability of the detection.

[0079] In this embodiment, the limiting members 62 located at the upper ends of the respective insulating base plates 3 are respectively connected, so as to drive a plurality of limiting members 62 to respectively push a plurality of insulating base plates 3 to move through one limiting driving member 61, reducing the cost. It can be understood that in other embodiments, a limiting member 62 can also be respectively arranged at the upper end of each insulating base plate 3.

[0080] In this embodiment, the insulating base plate 3 is made of bakelite material, and the bakelite material has the characteristics of insulation and wear resistance, ensuring the insulation between the metal part to be measured and the substrate 2, and improving the accuracy and reliability during detection. It can be understood that in other embodiments, the insulating base plate 3 can also be made of other insulating materials, such as rubber.

[0081] Refer to Figure 1 and Figure 7 as shown, Figure 7 which is a schematic structural diagram of the electronic control box of the metal part side hole plugging detection device provided by the embodiment of the present application. The metal part side hole plugging detection device further includes an electronic control box 7 and a terminal board 8. The electronic control box 7 is arranged on the second support portion 13 and is located below the substrate 2. The terminal board 8, the controller 5 and the power supply 9 are all arranged in the electronic control box 7. If the first input end is electrically connected to the conductive positioning block 41, the conductive probe 42 is electrically connected to the first electrode through the terminal board 8; if the first input end is electrically connected to the conductive probe 42, the conductive positioning block 41 is electrically connected to the first electrode through the terminal board 8. Among them, the controller 5 is a PLC controller, and the controller 5 further includes a common terminal, and the common terminal is connected to the second electrode of the power supply 9.

[0082] The power supply 9 further includes a controllable power switch, and the controller 5 is control-connected to the control end of the controllable power switch to realize the controller 5 controlling the turning on and off of the power supply 9.

[0083] The side of the insulating base plate 3 is provided with a sensor mounting hole 32, and a metal part placing sensor 10 is arranged at the sensor mounting hole 32. The metal part placing sensor 10 can be a proximity switch or a Hall sensor, etc., and is used to detect whether the measured metal part is placed on the insulating base plate 3. The controller 5 is connected to the metal part placing sensor 10 and is used to receive the detection signal of the metal part placing sensor 10.

[0084] In this embodiment, when the controller 5 detects that the measured metal part is placed in place based on the metal part placing sensor 10, it then controls the power supply 9 to conduct power supply, improving the safety of the detection process.

[0085] In this embodiment, the controller 5 is a PLC controller. The PLC controller has high stability and reliability, can ensure the continuity and safety of the working process, and the PLC controller has a fast response speed, small noise and low energy consumption, improving the detection efficiency and ensuring a quiet environment. It can be understood that in other embodiments, the controller 5 can also be a single-chip microcomputer.

[0086] On the basis of this embodiment, a metal part side hole plugging detection system is also disclosed, which includes a measured metal part feeding mechanism and the metal part side hole plugging detection device of any of the above embodiments. The measured metal part feeding mechanism is connected to the controller 5. The measured metal part feeding mechanism is used to transport the measured metal part to the detection position 21. Of course, it can also be used to transport the measured metal part located at the detection position 21 to the material box when the controller 5 receives an electrical signal, and transport the measured metal part located at the detection position 21 to the recycling box when the controller 5 does not receive an electrical signal.

[0087] In a specific application scenario, during operation, first, the measured metal part is transported to the detection position 21 through the transport mechanism, then the limit driving member 61 drives the limit member 62 to move, so that the limit member 62 pushes the measured metal part to abut against the conductive positioning block 41. Then, the position of the measured metal part is detected by the metal part placing sensor 10. The controller 5 controls the power supply 9 to supply power based on the detection result of the metal part placing sensor 10, so that the measured metal part and the conductive positioning block 41 can be electrically connected. After that, the probe driving member 43 drives the conductive probe 42 to move, so that the conductive probe 42 abuts against the target side hole. If the controller 5 does not receive an electrical signal, it proves that the conductive probe 42 and the conductive positioning block 41 cannot be electrically connected, and a hole plugging situation occurs. At this time, the controller 5 drives the metal part feeding mechanism to transport the measured metal part located at the detection position 21 to the recycling box for manual processing; if the controller 5 can receive an electrical signal, it proves that the conductive probe 42 and the conductive positioning block 41 are electrically connected and no hole plugging occurs. At this time, the controller 5 controls the metal part feeding mechanism to transport the measured metal part located at the detection position 21 to the material box, completing the hole plugging detection of the measured metal part.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
