[0001] This invention relates to the field of injection molded product testing technology, specifically to a missing part detection base and device. Background Technology
[0002] In the injection molding of connector products, if the metal insert is not removed from the mold along with the injection molded product, or if the injection molded metal insert is missing and not promptly removed, it will cause varying degrees of damage to the mold.
[0003] Traditional testing methods involve using a metal insert conductive fixture connected to an external digital multimeter. However, using a digital multimeter results in low testing efficiency. Operators must maintain constant contact between the fixture and the metal insert and observe the meter reading to determine if the conductivity is up to standard. The connection between the metal insert and the fixture is unstable, which increases the difficulty of testing, reduces the accuracy of the test results, increases working hours, and raises the labor intensity of the operators. Summary of the Invention
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art, such as the unstable connection between the injection-molded metal insert and the testing fixture, which leads to a decrease in the accuracy of the testing results, a longer testing time, and an increased testing difficulty, thereby providing a missing testing base and device.

[0009] According to a first aspect of the present invention, the positioning structure includes horizontal positioning members and angular positioning members, wherein multiple horizontal positioning members are provided and are evenly distributed circumferentially, and each of the multiple horizontal positioning members abuts against the inner side and / or outer side of the test piece; the angular positioning members are engaged with the positioning portion of the test piece so that the metal insert of the test piece is aligned and extends into the detection groove.
[0010] According to a first aspect of the present invention, the test piece is annular, the horizontal positioning member is frustum-shaped, and the horizontal positioning member abuts against the inner ring sidewall of the test piece.
[0011] According to a first aspect of the present invention, the detection grooves are provided in multiple quantities, and the number of metal inserts of the object to be detected is consistent with the number of the detection grooves, and the detection grooves are arranged at uniform intervals in a circumferential direction.
[0012] This invention also proposes a missing part detection device suitable for injection-molded metal inserts, comprising: a missing part detection base, a positioning sensor, a detection element, an actuator, and a controller; the part to be detected is disposed on the missing part detection base; the positioning sensor is disposed on the missing part detection base and is adapted to detect the positioning information of the part to be detected; the detection element is disposed on the missing part detection base and is adapted to connect with the metal insert of the part to be detected to form a closed loop; the actuator is disposed on the missing part detection base and has an on state and an off state. In the on state, the closed loop formed by the metal insert and the detection element is energized and outputs a detection signal; in the off state, the closed loop formed by the metal insert and the detection element is de-energized; the controller is disposed on the missing part detection base, and the positioning sensor, the detection element, and the actuator are all communicatively connected to the controller. The controller is adapted to receive the positioning information fed back by the positioning sensor to control the actuator to be in the on state or the off state, and the controller is adapted to receive the detection signal.
[0013] According to a second aspect of the present invention, the missing component detection device further includes an alarm device disposed on the missing component detection base, the alarm device being communicatively connected to the controller, and the controller being adapted to control the alarm device to output an alarm signal according to the detection signal.
[0014] According to a second aspect of the present invention, the warning signal includes at least a continue signal and a stop signal.
[0015] According to a second aspect of the present invention, the positioning sensor is an acoustic sensor, a photoelectric sensor, a radar sensor, or a pressure sensor.
[0016] The technical solution of this invention has the following advantages:
[0017] 1. The missing component detection base provided by the present invention uses a positioning structure to position and install the part to be tested, so that the metal insert of the part to be tested is aligned and extended into the detection groove, so as to facilitate the missing component detection of the part to be tested. The locking structure makes it easy to fix the part to be tested on the detection table, preventing the part to be tested from slipping during the detection process, which would affect the installation and detection of the metal insert, thereby improving the accuracy of the detection. At the same time, the missing component detection base can avoid the influence of human factors, further improving the accuracy of the detection and reducing labor costs.
[0018] 2. The missing material detection base provided by the present invention has a material picking groove and / or material picking hole on the mounting base to provide a gripping space, so as to facilitate material picking and replacement and improve detection efficiency.
[0019] 3. The missing component detection base provided by the present invention has a wire hole in the middle of the mounting base to facilitate the arrangement of the wires and avoid messy wiring that would affect the installation and testing of the component to be tested.
[0020] 4. The missing part detection platform provided by this invention has a horizontal positioning component adapted to limit the horizontal position of the part to be tested on the mounting base, preventing the part to be tested from sliding in the horizontal direction. The metal insert needs to be aligned and extended into the detection groove for easy detection. The angle positioning component is adapted to limit the rotation of the part to be tested, preventing misalignment between the metal insert and the detection groove. The locking structure is adapted to limit the vertical displacement of the part to be tested. The positioning structure and locking structure are suitable for fixing the part to be tested on the mounting platform to ensure the stability of the detection process and improve the accuracy of the detection.
[0021] 5. The missing part detection base provided by the present invention has a ring-shaped part to be tested and a frustum-shaped horizontal positioning part. The horizontal positioning part abuts against the inner ring sidewall of the part to be tested. Since the horizontal positioning part is frustum-shaped, when the horizontal positioning part abuts against the inner ring sidewall of the part to be tested, the two can fit tightly together, reducing the squeezing of the part to be tested, so as to ensure the integrity of the part to be tested.
[0022] 6. The missing component detection device provided by this invention provides a base for mounting a positioning sensor, a detection element, an actuator, and a controller. The positioning sensor is suitable for detecting the positioning information of the component to be tested. When the positioning sensor detects the presence of the component to be tested on the missing component detection base, it feeds the positioning information back to the controller. The controller then activates the actuator to energize the closed loop formed by the metal insert and the detection element to detect the component to be tested and output a detection signal. The controller receives the output detection signal and determines whether the component to be tested is missing. This missing component detection device achieves automatic detection, improving detection efficiency and the accuracy of the detected structure.
[0023] 7. The missing parts detection equipment provided by the present invention further includes an alarm device disposed on the missing parts detection base. The controller is adapted to control the alarm device to output an alarm signal according to the detection signal, so as to instruct the staff to continue the operation or terminate the operation, thereby realizing negative feedback control, improving the degree of automation, and improving the detection efficiency.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0033] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] Reference Figure 1 and Figure 4 As shown, the present invention proposes a missing part detection base, suitable for injection molded metal inserts, comprising: a detection platform 1, a positioning structure 2, and a locking structure 3. The detection platform 1 is provided with a detection groove 131; the positioning structure 2 is disposed on the detection platform 1, and the positioning structure 2 abuts against the inner and / or outer side of the part to be tested 4, so that the metal insert of the part to be tested 4 is aligned and extends into the detection groove 131; the locking structure 3 is disposed on the detection platform 1 and is adapted to fix the part to be tested 4 on the detection platform 1.
[0035] Metal insert injection molding is a type of insert molding where metal inserts are pre-fixed in appropriate positions within a mold, and then plastic is injected to form the insert. After mold opening, the insert is tightly encased and embedded within the product by the cooled and solidified plastic. The principle of injection molding connector fittings is the same. The injection-molded connector fittings are part 4 to be inspected, and it is necessary to check whether any metal inserts are missing.
[0036] See Figure 2 , Figure 3 and Figure 4As shown in the diagram, a detection slot 131 is provided on the detection table 1. A detection element 6, which can form a closed loop with the metal insert, is installed within the detection slot 131 for detecting the workpiece 4 to be tested. To ensure that the metal insert can be aligned and extended into the detection slot 131, the horizontal and angular displacements of the workpiece 4 to be tested are limited by the positioning structure 2, and the vertical displacement of the workpiece 4 to be tested is limited by the locking structure 3. This ensures that the metal insert can be aligned and extended into the detection slot 131 to connect with the detection element 6, thereby ensuring the stability of the workpiece 4 to be tested during the testing process and improving the accuracy of the detection structure. Simultaneously, this unmounted detection base avoids the influence of human factors, further improving the accuracy of the test and reducing labor costs.
[0037] It should be noted that the positioning structure 2 can be set on the outside of the part to be tested 4 and abut against the outer surface of the part to be tested 4 to clamp the part to be tested 4 and limit its horizontal position. Alternatively, the positioning structure 2 can be set on the inside of the part to be tested 4 and abut against the inner surface of the part to be tested 4 to limit its position. Or, the positioning structure 2 can form an installation track, and the part to be tested 4 can be set in the installation track. In this case, both the inner and outer sides of the part to be tested 4 abut against the positioning structure 2, and the positioning mechanism limits the horizontal position of the part to be tested.
[0038] It is understood that the locking structure 3 can be a bolt, with a fixing hole on the testing table 1 and an installation hole on the workpiece 4 to be tested. The bolt passes through the installation hole and is threadedly connected to the fixing hole to fix the workpiece 4 to be tested on the testing table 1. The locking structure 3 can also press the fixing buckle, which abuts against the upper surface of the workpiece 4 to make the lower surface of the workpiece 4 abut against the testing table 1, thereby limiting the vertical direction of the workpiece 4.
[0039] Multiple locking structures 3 may be provided and are evenly distributed circumferentially. In some embodiments of the present invention, multiple locking structures 3 are provided and are evenly distributed in a circle to improve the fixing stability of the test piece 4.
[0040] In a first aspect of the present invention, the testing station 1 includes a base 11, a connecting column 12 disposed on the base 11, and a mounting seat 13 fixedly mounted on the base 11 via the connecting column 12. The mounting seat 13 is provided with a material picking groove 132 and / or a material picking hole 133. The material picking hole 133 and the material picking groove 132 are both offset from the testing groove 131. The opening of the material picking groove 132 faces upward, and one side extends through the outer edge of the mounting seat 13.
[0041] Specifically, the lower surface of the part to be tested 4 is in contact with the upper surface of the mounting base 13. A material picking groove 132 and / or a material picking hole 133 are provided on the mounting base 13 to provide gripping space, so as to facilitate material picking and replacement and improve testing efficiency.
[0042] In a first aspect embodiment of the present invention, a wire hole 134 is provided in the middle of the mounting base 13.
[0043] Specifically, a wire hole 134 is provided in the middle of the mounting base 13 to facilitate the arrangement of wires and avoid messy wiring that would affect the installation and testing of the component 4 to be tested.
[0044] In a first aspect of the present invention, the positioning structure 2 includes horizontal positioning members 21 and angular positioning members 22. The horizontal positioning members 21 are provided in multiple and are evenly distributed in the circumferential direction. The multiple horizontal positioning members 21 abut against the inner side and / or outer side of the member to be tested 4. The angular positioning members 22 are connected to the positioning part of the member to be tested 4 so that the metal insert of the member to be tested 4 is aligned and extends into the detection groove 131.
[0045] Reference Figure 2 and Figure 3 As shown, specifically, the positioning structure 2 includes a horizontal positioning element 21 and an angular positioning element 22. The horizontal positioning element 21 is adapted to limit the horizontal position of the part to be tested 4 on the mounting base 13, preventing the part to be tested 4 from slipping in the horizontal direction. The metal insert needs to be aligned and extended into the detection groove 131 for detection. The angular positioning element 22 is adapted to limit the rotation of the part to be tested 4, preventing misalignment between the metal insert and the detection groove 131. The locking structure 3 is adapted to limit the vertical displacement of the part to be tested 4. The positioning structure 2 and the locking structure 3 are adapted to fix the part to be tested 4 on the mounting platform to ensure the stability of the detection process of the part to be tested 4 and improve the accuracy of the detection.
[0046] In a first aspect of the present invention, the test piece 4 is annular, the horizontal positioning piece 21 is frustum-shaped, and the horizontal positioning piece 21 abuts against the inner ring sidewall of the test piece 4.
[0047] Understandably, the part to be tested 4 is annular, and the horizontal positioning parts 21 are evenly distributed circumferentially. To ensure the horizontal limiting of the part to be tested 4, the horizontal positioning parts 21 are shaped like a frustum and are located on the inner side of the inner ring of the part to be tested 4, abutting against the inner ring sidewall of the part to be tested 4. At this time, the arcuate sidewall of the horizontal positioning part 21 fits against the inner ring sidewall of the part to be tested 4, thus achieving limiting. When the part to be tested 4 is arcuate, and the arcuate opening faces inward, the horizontal positioning parts 21 are located on the relatively outer side of the part to be tested 4 and fit against the outer ring sidewall of the part to be tested 4, thus limiting the part to be tested 4.
[0048] Understandably, the horizontal positioning component 21 is made of an elastic material, specifically rubber or silicone, to ensure the fit between the component 4 to be tested and the horizontal positioning component 21 while preventing the component 4 from being squeezed and damaged. This ensures the integrity of the component 4 to be tested.
[0049] In a first aspect embodiment of the present invention, a plurality of detection grooves 131 are provided, and the number of metal inserts is consistent with that of the test piece 4. The detection grooves 131 are arranged in a circumferentially uniform interval.
[0050] Understandably, the number of detection slots 131 needs to be consistent with the number of metal inserts on the part to be tested 4.
[0051] This invention also proposes a missing part detection device suitable for injection-molded metal inserts, comprising: a missing part detection base, a position sensor 5, a detection element 6, an actuator, and a controller; the part to be detected 4 is disposed on the missing part detection base; the position sensor 5 is disposed on the missing part detection base and is adapted to detect the position information of the part to be detected 4; the detection element 6 is disposed on the missing part detection base and is adapted to connect with the metal insert of the part to be detected 4 to form a closed loop; the actuator is disposed on the missing part detection base and has an on state and an off state. In the on state, the closed loop formed by the metal insert and the detection element 6 is energized and outputs a detection signal; in the off state, the closed loop formed by the metal insert and the detection element 6 is de-energized; the controller is disposed on the missing part detection base, and the position sensor 5, the detection element 6, and the actuator are all communicatively connected to the controller. The controller is adapted to receive the position information fed back by the position sensor 5 to control the actuator to be in the on state or the off state, and the controller is adapted to receive the detection signal.
[0052] Specifically, the missing component detection base provides a mounting foundation for the positioning sensor 5, detection element 6, actuator, and controller. The positioning sensor 5 is suitable for detecting the positioning information of the component to be tested 4. When the positioning sensor 5 detects the presence of the component to be tested 4 on the missing component detection base, it feeds the positioning information back to the controller. The controller then activates the actuator to energize the closed loop formed by the metal insert and detection element 6 to detect the component to be tested 4 and output a detection signal. The controller receives the output detection signal and determines whether the component to be tested 4 is missing. This missing component detection equipment achieves automatic detection, improving detection efficiency and the accuracy of the detected structure.
[0053] Specifically, the positioning sensor 5 can be an acoustic sensor, a photoelectric sensor, a radar sensor, or a pressure sensor. In some embodiments of the present invention, the positioning sensor 5 is a photoelectric sensor, which includes a photoelectric generator and a photoelectric receiver. The photoelectric generator and the photoelectric receiver are arranged opposite each other and are located on opposite sides of the inner and outer sides of the object to be detected 4. The photoelectric generator emits light. When the object to be detected 4 is installed and fixed on the detection table 1, the object to be detected 4 blocks the propagation of the light. At this time, the controller receives the positioning information emitted by the positioning sensor 5 and controls the actuator to start.
[0054] It is understood that the actuator is a power switch. When the actuator is activated, the closed loop formed by the metal insert and the detection element 6 is energized, enabling the detection of the item 4 to be detected. When the actuator is deactivated, the closed loop formed by the metal insert and the detection element 6 is de-energized. After the closed loop formed by the metal insert and the detection element 6 is energized, a detection signal is output and fed back to the controller.
[0055] The detection element 6 is a detection probe, which contacts and connects with the metal insert to form a closed loop. Specifically, the detection element 6 is disposed in the detection groove 131, and when the metal insert is aligned and extends into the detection groove 131, it can contact and connect with the detection probe.
[0056] In a second aspect of the present invention, the missing part detection device further includes an alarm device disposed on the missing part detection base, the alarm device being communicatively connected to a controller, and the controller being adapted to control the alarm device to output an alarm signal according to the detection signal.
[0057] In a second aspect of the invention, the warning signal includes at least a continue signal and a stop signal.
[0058] Specifically, the missing parts detection equipment also includes an alarm device installed on the missing parts detection base. The controller is adapted to control the alarm device to output an alarm signal according to the detection signal, so as to instruct the staff to continue or terminate the operation, realize negative feedback control, improve the degree of automation, and improve detection efficiency.
[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
