In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0048] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 In a first aspect, an embodiment of the present application provides a pushing mechanism 10 , which is used in a connector detection device 100 , and the connector detection device 100 includes a detection component 20 .

[0050] The pushing mechanism 10 includes a support member 11 and a push-pull assembly. The support member 11 is provided with a slide groove 111 for accommodating the connector 200. The slide groove 111 extends along a first direction, and the first direction can be along the X direction in the figure. The slide groove 111 is provided with a detection part 112 corresponding to the detection component 20. The detection component 20 can detect whether the LED inside the connector 200 in the detection part 112 is turned on.

[0051] The push-pull assembly includes a push-pull member 12 and a first telescopic member 13 connected to the push-pull member 12 . The first telescopic member 13 is used to drive the push-pull member 12 to move along a first direction, so that the push-pull member 12 can push the connector 200 to move to the detection portion 112 .

[0052] For example, the first telescopic member 13 may include a cylinder, a hydraulic cylinder, a linear module or a lead screw motor.

[0053] The first telescopic member 13 can drive the push-pull member 12 to move along the first direction, so that the push-pull member 12 can push the connector 200 to move from other positions in the slide groove 111 to the detection portion 112 along the first direction. The slide groove 111 can limit the connector 200 during its movement.

[0054] The pushing mechanism 10 provided in the embodiment of the present application includes a supporting member 11 and a push-pull assembly, the supporting member 11 is provided with a slide groove 111 for accommodating the connector 200, the slide groove 111 extends along a first direction, the slide groove 111 is provided with a detection portion 112 corresponding to the detection assembly 20, and the push-pull assembly includes a push-pull member 12 and a first telescopic member 13 connected to the push-pull member 12, so the push-pull member 12 can be driven by the first telescopic member 13 to move along the first direction, so that the push-pull member 12 can push the connector 200 to automatically move to the detection portion 112, and the slide groove 111 can limit the connector 200 during the movement of the connector 200, the whole process does not require manual operation, and can solve the problem that the detection process of the connector detection device 100 is inefficient, time-consuming and labor-intensive.

[0055] Please refer to Figure 4 In this embodiment, the first telescopic member 13 is used to drive the push-pull member 12 to move along a first direction, and the first telescopic member 13 is used to drive the push-pull member 12 to move along a second direction opposite to the first direction, and the second direction can be along the negative X direction in the figure.

[0056] The push-pull assembly includes a connecting member 14, a first telescopic member 13 connected to the connecting member 14, a push-pull member 12 rotatably connected to the connecting member 14, and the first telescopic member 13 can drive the push-pull member 12 to move along the second direction, so that the push-pull member 12 rotates relative to the connecting member 14 after contacting the connector 200.

[0057] By adopting the above scheme, the first telescopic member 13 can be used to drive the push-pull member 12 to move along the first direction, so that the push-pull member 12 pushes the connector 200 to move from other positions in the slide groove 111 along the first direction to the detection part 112, and when the first telescopic member 13 can drive the push-pull member 12 to move along the second direction, the push-pull member 12 can rotate relative to the connecting member 14 after contacting the connector 200, so as to avoid interference between the push-pull member 12 and the next connector 200 arranged along the second direction.

[0058] For example, the first telescopic member 13 drives the push-pull member 12 to move along the first direction, so that after the push-pull member 12 pushes the connector 200 to move from other positions in the slide groove 111 along the first direction to the detection portion 112, the first telescopic member 13 drives the push-pull member 12 to move along the second direction. During this process, the push-pull member 12 rotates relative to the connecting member 14 after contacting the next connector 200 to avoid interference between the push-pull member 12 and the next connector 200, thereby avoiding the push-pull member 12 pushing the connector 200 to move along the second direction in the slide groove 111.

[0059] Specifically, at least two push-pull members 12 are provided, and all the push-pull members are arranged at equal intervals along the first direction. In this way, multiple connectors 200 can be placed in the slide slot 111 at the same time, and when the first telescopic member 13 drives the push-pull member 12 to move along the first direction, it can drive multiple push-pull members 12 to move along the first direction, so that multiple push-pull members 12 can be pushed to move in the slide slot 111 at the same time.

[0060] Optionally, the first telescopic member 13 is connected to a connecting rod (not shown in the figure), and all the connecting members are connected to the connecting rod.

[0061] In this embodiment, the connecting member 14 is provided with a receiving groove 141 extending along the first direction, and the push-pull assembly includes a rotating shaft (not shown in the figure) and a first elastic member 15, and the axis of the rotating shaft is perpendicular to the first direction.

[0062] The push-pull member 12 includes a first portion 121 and a second portion 122. The first portion 121 is used to push the connector 200. The second portion 122 extends to the interior of the accommodating groove 141. The second portion 122 is rotatably connected to the connecting member 14 via a rotating shaft. The rotating shaft separates the second portion 122 into a supporting portion 1221 and a connecting portion 1222 arranged along a first direction. The opposite ends of the first elastic member 15 respectively abut against the bottom surface of the accommodating groove 141 and the connecting portion 1222, so that the supporting portion 1221 abuts against the bottom surface of the accommodating groove 141.

[0063] By adopting the above solution, when the first telescopic member 13 can drive the push-pull member 12 to move along the second direction, the push-pull member 12 can rotate relative to the connecting member 14 after contacting the connector 200 to avoid interference between the push-pull member 12 and the next connector 200.

[0064] It can be understood that when the first telescopic member 13 is able to drive the push-pull member 12 to move along the second direction, the first elastic member 15 will be compressed by force after the push-pull member 12 contacts the next connector 200, so that the push-pull member 12 rotates relative to the connecting member 14, thereby preventing the push-pull member 12 from pushing the next connector 200 to move along the second direction in the slide groove 111.

[0065] Optionally, the first elastic member 15 may be a spring or elastic rubber, etc. The first portion 121 and the second portion 122 may define two ends of the push-pull member 12 respectively.

[0066] Specifically, the support member 11 is provided with a avoidance groove 113, which runs through the bottom wall of the slide groove 111, and the avoidance groove 113 extends along the first direction. The push-pull member 12 extends from the outside of the support member 11 to the inside of the slide groove 111 through the avoidance groove 113. The first telescopic member 13 can drive the push-pull member 12 to move along the second direction, so that the push-pull member 12 rotates relative to the connecting member 14 to the avoidance groove 113.

[0067] With such a configuration, the avoidance groove 113 can be used to limit the position of the push-pull member 12, and when the first telescopic member 13 can drive the push-pull member 12 to move along the second direction, the push-pull member 12 can rotate relative to the connecting member 14 after contacting the connector 200, so as to avoid interference between the push-pull member 12 and the next connector 200.

[0068] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In a second aspect, an embodiment of the present application provides a connector detection device 100, comprising a detection component 20 and a pushing mechanism 10 as in the first aspect.

[0069] The connector detection device 100 provided in the embodiment of the present application has a pushing mechanism 10 including a support member 11 and a push-pull assembly, the support member 11 is provided with a slide groove 111 for accommodating the connector 200, the slide groove 111 extends along a first direction, the slide groove 111 is provided with a detection portion 112 corresponding to the detection assembly 20, and the push-pull assembly includes a push-pull member 12 and a first telescopic member 13 connected to the push-pull member 12, so the push-pull member 12 can be driven by the first telescopic member 13 to move along the first direction, so that the push-pull member 12 can push the connector 200 to automatically move to the detection portion 112, and the slide groove 111 can limit the connector 200 during the movement of the connector 200, the entire process does not require manual operation, and can solve the problem that the detection process of the connector detection device 100 is inefficient, time-consuming and labor-intensive.

[0070] Specifically, the detection assembly 20 includes a second telescopic member 21 and a continuity test fixture 22 . The second telescopic member 21 is used to drive the continuity test fixture 22 to move closer to or away from the connector 200 .

[0071] With such a configuration, the second telescopic member 21 can be used to drive the continuity test fixture 22 close to the connector 200 to detect the connector 200, and after the detection is completed, the second telescopic member 21 can be used to drive the continuity test fixture 22 away from the connector 200 so that the connector 200 continues to move in the first direction in the slide slot 111.

[0072] It should be noted that when the connector 200 is tested, the LED has been installed in the main LED slot of the connector 200, but the LED lamp pin 210 has not been bent or trimmed. The process of installing the LED in the main LED slot of the connector 200 can be performed using an LED assembly component.

[0073] For example, the second telescopic member 21 may include a cylinder, a hydraulic cylinder, a linear module or a lead screw motor, etc. The conduction test fixture may be provided with 8 probes. When testing the LED lamp pins 210 of the contact connector 200, every 2 probes contact the positive and negative LED lamp pins 210 (PIN pins) of an LED.

[0074] The conventional connector detection device 100 only designs a corresponding test circuit to detect whether the LED is turned on, but does not directly reflect the information observed by the user: that is, the brightness of the LED. Therefore, some unqualified products that pass the conduction test but have dim lights are missed.

[0075] To solve the above problem, the connector detection device 100 optionally further includes a camera 30, which is used to take a photo of the connector 200 located in the detection part 112. In this way, the connector 200 located in the detection part 112 can be photographed and detected by the camera 30, so that the detection result is more accurate.

[0076] It can be understood that by processing the image captured by the camera 30, the information observed by the user is directly reflected: that is, the brightness of the LED. The quality of the connector 200 with LED is improved. At the same time, it is achieved to intercept defective products with dim lights before LED processing, avoiding the need to disassemble and repair fully assembled defective products. In addition, the image processing archived pictures facilitate the production line to trace quality problems, and more completely record the lighting inspection status of each connector 200, which assists process control.

[0077] It should be noted that by utilizing the characteristics of the LED itself emitting light and the LED being deeper in the LED slot of the connector 200 and selecting a suitable shooting angle, the connector 200 can be directly photographed without the need for lighting or shading design.

[0078] Optionally, the camera 30 is mounted at the detection portion 112 , with the lens of the camera 30 facing the connector 200 of the detection portion 112 , and the center point of the lens of the camera 30 and the LED light cap of the connector 200 to be detected are in the same horizontal plane.

[0079] In order to ensure that the connector 200 and the support member 11 do not move relatively to a large extent after the first telescopic member 13 drives the push-pull member 12 to move along the first direction, so that the push-pull member 12 pushes the connector 200 in the slide groove 111 from other positions along the first direction to the detection portion 112, please refer to Figure 7 and Figure 8 In this embodiment, the connector detection device 100 includes a fixing component 40 , which is connected to the support member 11 , and the fixing component 40 is used to limit the relative position of the connector 200 and the support member 11 .

[0080] With such configuration, the relative position of the connector 200 and the support member 11 can be limited by the fixing component 40 , thereby facilitating the detection component 20 to detect the connector 200 .

[0081] Specifically, the fixing assembly 40 includes a cover plate 41 , which is connected to the support member 11 , and at least a portion of the cover plate 41 is located above the detection portion 112 .

[0082] With such arrangement, after the connector 200 moves to the detection portion 112 , the cover plate 41 can be used to limit the relative position of the connector 200 and the support member 11 , thereby preventing the connector 200 from moving randomly in the slide groove 111 .

[0083] The cover plate 41 can be used to contact the connector 200 in the slide slot 111. In this way, the relative position of the connector 200 and the support member 11 can be better defined by the cover plate 41, so as to prevent the connector 200 from moving randomly in the slide slot 111.

[0084] Optionally, the fixing assembly 40 includes a clamping member 42, which is connected to the cover plate 41 and is used to hold the connector 200. In this way, the clamping member 42 can be used to clamp the connector 200 to limit the relative position of the connector 200 and the support member 11, thereby preventing the connector 200 from moving randomly in the slide groove 111.

[0085] For example, the fixing assembly 40 includes a mounting member 44 and a second elastic member 45, the mounting member 44 is disposed on a side of the cover plate 41 away from the support member 11 and connected to the cover plate 41, the clamping member 42 is movably connected to the cover plate 41, and the two opposite ends of the second elastic member 45 respectively abut the clamping member 42 and the mounting member 44, so that the clamping member 42 abuts the connector 200. Such a configuration can ensure that the clamping member 42 abuts the connector 200 during the detection process, and ensure that the push-pull member 12 can push the connector 200 away after the detection is completed.

[0086] It should be noted that the clamping member 42 can move relative to the cover plate 41 in a direction close to and away from the connector 200. The clamping member 42 can be configured to be slidably connected to the cover plate 41, for example, the cover plate 41 is provided with a sliding groove (not shown in the figure), and the clamping member 42 is slidably arranged in the sliding groove.

[0087] There may be at least two of each of the clamping member 42 and the second elastic member 45 disposed along the first direction. The second elastic member 45 may be a spring or elastic rubber.

[0088] Specifically, the connector 200 includes an LED lamp pin 210, and the fixing component 40 includes a magnetic member 43, which is connected to the support member 11 and is used to absorb the LED lamp pin 210. In this way, the LED lamp pin 210 can be fixed by the magnetic member 43, so that the detection component 20 can detect the LED lamp pin 210.

[0089] Optionally, the magnetic attraction member 43 may be a rubber soft magnetic sheet. A steel pad is installed on the support member 11, and a rubber soft magnetic sheet is attached to the steel pad. When the connector 200 reaches the detection unit 112, the rubber soft magnetic sheet provides a slight adsorption force to the LED lamp pin 210, ensuring that the LED lamp pin 210 is within the contact range of the probe of the conduction test fixture 22.

[0090] In this embodiment, the connector detection device 100 includes a loading component 50, which includes a loading part 51 and a third telescopic part 52 connected to the loading part 51. The third telescopic part 52 is used to drive the loading part 51 to move along a third direction so that the loading part 51 can push the connector 200 to move into the slide groove 111. The third direction is set at an angle to the first direction.

[0091] By adopting the above scheme, the third telescopic member 52 can drive the loading member 51 to move along the third direction, so that the loading member 51 can push the connector 200 to move into the slide groove 111, thereby dividing the multiple continuously arranged connectors 200 into an interleaved arrangement and moving them into the slide groove 111.

[0092] It can be understood that the connector detection device 100 provided in the embodiment of the present application does not require manual pulling, loading and unloading, and will not generate high additional labor costs and material losses.

[0093] For example, the third telescopic member 52 may include a cylinder, a hydraulic cylinder, a linear module or a lead screw motor, etc. The third direction may be arranged at right angles to the first direction. The third direction may be along the negative Y direction in the figure.

[0094] Specifically, the loading member 51 includes a main body and a limiting groove 511 provided in the main body, the limiting groove 511 is used to accommodate the connector 200, and the limiting groove 511 extends along the first direction and penetrates the main body. In this way, the position of the connector 200 can be limited by the limiting groove 511, so that the loading member 51 can be driven to move along the third direction by the third telescopic member 52, so that the loading member 51 can push the connector 200 to move into the slide groove 111 to prevent the connector 200 from moving randomly.

[0095] Optionally, the embodiment of the present application further includes a controller, which may be a PLC (Programmable Logic Controller) or a single chip microcomputer, and the first telescopic member 13, the second telescopic member 21, the third telescopic member 52 and the continuity test fixture 22 are all connected to the controller. In this embodiment, the controller is a PLC.

[0096] Please refer to Figures 1 to 8 The connector detection device 100 provided in the embodiment of the present application may include the following steps when used:

[0097] First, perform detection action one.

[0098] Specifically, docking with upstream incoming materials. The upstream incoming materials can be a plurality of connectors 200 arranged continuously and conveyed by a conveyor belt. After a single connector 200 enters the limit groove 511, the PLC receives the corresponding material sensor signal, and the PLC controls the third telescopic member 52 to extend, driving the single feeding member 51 and the single connector 200 to align with the downstream slide 111. The PLC receives the corresponding in-place sensor signal of the third telescopic member 52, and the PLC controls the first telescopic member 13 to extend, driving the push-pull member 12 to push the connector 200 to the detection part 112, and limits the relative position of the connector 200 and the support member 11 through the fixing component 40 to complete the feeding action.

[0099] Next, perform detection action 2.

[0100] Specifically, the PLC receives the in-position sensor signal corresponding to the first telescopic member 13, and the PLC controls the first telescopic member 13 to retract. The push-pull member 12 rotates relative to the connecting member 14 after contacting the next connector 200 to avoid interference between the push-pull member 12 and the next connector 200. The push-pull member 12 is able to avoid air and return to its initial position, and the return sensor corresponding to the first telescopic member 13 sends a signal.

[0101] Next, detection action three is performed.

[0102] Specifically, the PLC receives the return sensor signal corresponding to the first telescopic part 13, and the PLC controls the second telescopic part 21 to extend, driving the conductivity test fixture 22 to descend, and the in-position sensor corresponding to the second telescopic part 21 sends a signal. At this time, the probe of the conductivity test fixture 22 contacts the LED lamp pin 210 of the connector 200 to be tested, and the LED is connected to the conductivity test circuit to start testing. The PLC determines whether each LED lamp is turned on based on whether the input terminal is turned on.

[0103] Then, detection action four is performed.

[0104] Specifically, after the PLC conduction test is completed, the PLC control triggers the camera 30 to collect images, and the visual inspection system starts the inspection. After the inspection is completed, a signal indicating whether the connector 200 is qualified or unqualified is issued.

[0105] Finally, detection action five is executed.

[0106] Specifically, the PLC receives a qualified or unqualified signal from the visual inspection system and performs a logical “AND” calculation with the conduction test result.

[0107] If the result is true, the PLC determines that the connector 200 is qualified, and the PLC controls the second telescopic part 21 to retract, driving the conduction test fixture 22 to rise, and the return sensor corresponding to the second telescopic part 21 sends a signal. At this time, the probe of the conduction test fixture 22 is separated from the LED, and a qualified product detection cycle is completed.

[0108] If the result is false, the PLC determines that the connector 200 is unqualified, and the PLC controls the second telescopic member 21 to retract, driving the conduction test fixture 22 to rise. The return sensor corresponding to the second telescopic member 21 sends a signal, and the PLC receives the return sensor signal corresponding to the second telescopic member 21. At this time, the PLC performs a second retest, repeating the detection of actions three and four. The result of the second retest is still false. Finally, the PLC determines that the connector 200 is unqualified, and the PLC controls the second telescopic member 21 to retract, driving the conduction test fixture 22 to rise. At this time, the probe of the conduction test fixture 22 is separated from the LED, and the touch screen displays the unqualified LED information, prompting the operator to replace the LED component. At this time, a defective product detection cycle is completed. After the operator replaces the LED and restarts the equipment, the PLC clears the product unqualified signal cache and performs detection action three.

[0109] Please refer to Fig. 9 In the third detection action, the conduction test circuit is powered by a 5V DC power supply, and R1~R4 are current limiting resistors to prevent the test current from being too large. D1~D4 are LED lights that need to be tested, and U1~U4 are optocoupler isolation chips (EL821). If the LED light is normal, the MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) tube has current input, its output end is turned on, and the PLC receives a conduction signal and determines that the LED is qualified; if the LED light is installed upside down, the MOS tube has no current input, its output end is not turned on, and the PLC does not receive a conduction signal, and determines that the LED is unqualified. D5~D8 are voltage-stabilizing diodes to prevent the PLC from receiving abnormal signals.

[0110] In the fourth detection action, after the PLC conduction test is completed, the PLC controls the triggering signal to be transmitted to the host computer through the RS485 serial port protocol. The host computer algorithm software calls the SDK (Software Development Kit) of the camera 30 to trigger the camera 30 to collect images. The camera 30 starts to collect RGB (red green blue) image signals and transmits them to the host computer through the industrial Ethernet TCP (Transmission Control Protocol) protocol. The signal interaction diagram is shown in the figure below. Fig.10 shown.

[0111] Specifically, after the host computer receives the RGB image signal, the algorithm software starts to process the RGB image signal:

[0112] 1. The software displays the acquired image and displays the corresponding red-bordered rectangle on its layer, which is the image region of interest (hereinafter referred to as ROI) of the LED to be tested.

[0113] 2. The software captures the pixel information of ROI (Region Of Interest), traverses and counts the G and B channel values ​​of all pixels in ROI, and if the pixel satisfies the G channel value > preset G channel value and the B channel value < preset B channel value, the count of the pixel that meets the conditions is increased by one.

[0114] 3. The software obtains the pixel counts that meet the conditions in each ROI and displays them as the corresponding LED brightness value. If the brightness > preset value, the product is considered qualified.

[0115] After the algorithm software determines the qualified and unqualified signals of the product, it transmits them to the PLC of the connector 200 assembly equipment through the RS485 serial port protocol. The PLC executes conditional branch actions based on the signals: if it is qualified, production continues; if it is unqualified, an alarm is issued and a prompt is given to replace the LED at the specific location.
