Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0034] Example, refer to Figures 1-4 An interface-type LED light strip workpiece inspection device includes a housing 1, a support assembly inside the housing 1, a plurality of first support rods 6 fixedly connected to the housing 1, a plurality of second support rods 7 fixedly connected to the top of the first support rods 6, and a plurality of third support rods 8 fixedly connected to the top of the second support rods 7. The device also includes: a positioning insertion assembly disposed on the first support rods 6, used to illuminate the workpiece to be inspected; a limiting conveying assembly disposed on the second support rods 7, used to position the workpiece; and a vision inspection assembly disposed on the third support rods 8, used to inspect for problems on the workpiece.

[0035] A control console 2 is installed on the housing 1, which works in conjunction with the PLC and various actuators of the equipment as a human-machine interface terminal for operators to preset control programs, adjust equipment parameters, and start / stop equipment operation. A first operating port 3 is opened on one side of the housing 1, and a second operating port 4 is opened on the other side. A maintenance port 5 is provided on the housing 1 for operators to inspect, maintain, and replace internal components of the equipment.

[0036] The positioning and insertion assembly includes a first slide bar 11 and a second slide bar 12 fixedly connected to the first support rod 6. A first lead screw 13 and a second lead screw 14 are respectively disposed above the first slide bar 11 and the second slide bar 12. A first moving rod 15 and a second moving rod 16 are slidably connected to the first slide bar 11 and the second moving rod 12. A third lead screw 17 and a fourth lead screw 18 are respectively disposed above the first moving rod 15 and the second moving rod 16. The ends of the first lead screw 13 and the first moving rod 15 are connected by a threaded engagement, and the ends of the second lead screw 14 and the second moving rod 16 are also connected by a threaded engagement. A first slider 19 is slidably disposed on both the first moving rod 15 and the second moving rod 16. The second lead screw 14 cooperates with the first lead screw 13, the fourth lead screw 18, and the positioning and insertion assembly, serving as an auxiliary transmission component for planar positioning, and working in conjunction with the first lead screw 13 and the fourth lead screw 18 to drive the first moving rod 15, the second moving rod 16, and related components to move smoothly.

[0037] Reference Figure 5The top of the first slider 19 is slidably connected to the second slider 22. The top of the second slider 22 is fixedly connected to the stabilizer 24. The stabilizer 24 is fixedly connected to the third slider 25. The third slider 25 is slidably connected to the moving plate 26. The side wall of the stabilizer 24 is fixedly connected to the fixed plate 27. The bottom of the fixed plate 27 is fixedly connected to the displacement motor 31. The output shaft of the displacement motor 31 is fixedly connected to the fifth lead screw 32. The fifth lead screw 32 is connected to the moving plate 26 through a threaded connection. The bottom of the moving plate 26 is fixedly connected to the rotary motor 33. The top of the moving plate 26 is rotatably connected to the rotary frame 34. The rotary frame 34 is fixedly connected to the output shaft of the rotary motor 33. The rotary frame 34 is fixedly connected to the plug 35. The bottom of the moving plate 26 is fixedly connected to the first industrial camera 36. An aperture 37 is set above the first industrial camera 36 to avoid interface positioning deviation caused by light problems.

[0038] It should be noted that: when the positioning and plugging assembly is activated, the first industrial camera 36 on it starts working, taking an image of the bottom interface of the lamp board 48, locating the interface position and calculating the coordinates through image recognition technology; after the coordinate calculation is completed, the positioning program is started: driving the first lead screw 13 and the fourth lead screw 18 to rotate, driving the first moving rod 15, the second moving rod 16 and related components to move, completing the planar positioning of the plug 35 relative to the lamp board interface; after the planar positioning is completed, the displacement motor 31 drives the fifth lead screw 32 to rotate, driving the moving plate 26 and the plug 35 to move upward, inserting the plug 35 into the lamp board interface; if a vertical interface is encountered, the first industrial camera 36 takes another picture for positioning, and then drives the rotating frame 34 to rotate 90 degrees through the rotary motor 33 to adjust the orientation of the plug 35, and complete the plugging after repositioning, ensuring stable power supply to the lamp board 48.

[0039] Reference Figures 6-8 The limiting conveying assembly includes two fourth slide bars 41 fixedly connected to the second support rod 7. A third slider 42 is slidably connected to the fourth slide bar 41. A sixth lead screw 43 is provided above the third slider 42. The sixth lead screw 43 and the third slider 42 are driven by threaded engagement. A third moving rod 44 is fixedly connected to the third slider 42.

[0040] A fixing rod 47 is fixedly connected to the second support rod 7. A light plate 48 is provided on the inner side of the fixing rod 47. A pressure plate 51 is provided above both the fixing rod 47 and the third moving rod 44. Multiple limit cylinders 45, fixing cylinders 46 and connecting brackets 52 are fixedly connected to the outer sides of the fixing rod 47 and the third moving rod 44. A limit strip 53 is fixedly connected to the end of the piston rod of the limit cylinder 45.

[0041] The piston rod end of the fixed cylinder 46 is fixedly connected to the pressure plate 51. A background suppression photoelectric sensor is fixedly connected to the connecting frame 52. Both ends of the fixed rod 47 and the third moving rod 44 are equipped with drive motors. The output ends of the drive motors are equipped with synchronous belts 54. Multiple support bars are provided below the synchronous belts 54.

[0042] The fixed rod 47 and the third moving rod 44 are provided with a limit cylinder 45, a connecting frame 52 and a fixed cylinder 46 in sequence from the end to the middle. The fixed rod 47 is fixedly connected to the connecting frame 52 at both ends.

[0043] It should be noted that before the device is put into operation, the initial parameters are adjusted through a preset program: the two sixth lead screws 43 are driven to rotate synchronously, which drives the third slider 42 and the third moving rod 44 to move, thereby adjusting the gap between the fixed rod 47 and the third moving rod 44 so that it is slightly larger than the width of the lamp plate 48, in order to prepare for subsequent feeding and detection.

[0044] After the equipment is started, the light panel 48 is sent into the limiting conveying assembly from the first operation port 3; when the background suppression photoelectric sensor at the end of the fixed rod 47 detects the occlusion signal, the equipment automatically starts to run, controls the drive motors at both ends of the fixed rod 47 to work, drives the synchronous belt 54 to rotate, and the support bar under the synchronous belt 54 forms a stable support for the synchronous belt 54 to ensure smooth conveying.

[0045] The light panels 48 enter the limiting conveying assembly in a continuous manner with gaps between each pair: the first light panel 48 first passes the sensor on the connecting frame 52 on one side of the first operating port 3. After the sensor detects an obstruction signal, it controls the limiting bar 53 of the limiting cylinder 45 next to the second operating port 4 to extend, restricting the passage of the light panel 48; when the sensor detects the passage of the second light panel, it controls the limiting bar 53 at the end of the first operating port 3 to extend, restricting the subsequent light panels from entering, thus allowing both light panels 48 to enter the limiting conveying assembly. The sensor on the connecting frame 52 at the end of the second operating port 4 monitors the position of the light panels in real time. If no light panel is detected, the equipment reports an error, ensuring the standardization of the detection process.

[0046] At this time, the drive motor stops running and the synchronous belt 54 stops conveying; then the piston rods of multiple fixed cylinders 46 are controlled to retract, driving the pressure plate 51 to press down. The pressure plate 51 and the support bar below the synchronous belt 54 cooperate with each other to clamp the two lamp plates 48, thereby fixing the position of the lamp plates and providing a stable reference for subsequent positioning and visual inspection.

[0047] Reference Figures 9-10The visual inspection component includes two fifth slide bars 61 fixedly connected to the top of the third support rod 8. A fourth slider 62 is slidably mounted on the fifth slide bar 61. A positioning pin 63 is provided on the fourth slider 62 to fix the position of the slider and prevent the slider from moving arbitrarily. A fourth moving rod is fixedly connected to the fourth slider 62, and a connecting seat 64 is fixedly connected to the fourth moving rod.

[0048] Multiple sixth slide bars 65 are fixedly connected to the connecting base 64. A drive motor is fixedly connected to the connecting base 64. A seventh lead screw 66 is fixedly connected to the output shaft of the drive motor. A displacement rod 67 is slidably connected to the sixth slide bar 65. The seventh lead screw 66 is connected to the displacement rod 67 via a threaded connection. Two fifth sliders 68 are slidably connected to the displacement rod 67. A second industrial camera 69 is fixedly connected to the fifth slider 68. A matching motor is provided at the end of the seventh lead screw 66 to provide driving force for the position adjustment of the vision inspection component. The motor drives the seventh lead screw 66 to rotate, thereby moving the sliders and the inspection component. With the control instructions of the PLC, the automated position adjustment of the inspection component is realized.

[0049] It should be noted that after the light board 48 is powered on, the vision inspection component is activated, and the second industrial camera 69 on it takes pictures of the surface of the light board. Through image comparison technology, the on / off state of the LED light strips on the light board is identified, the quality of the light strips is judged, and the inspection operation is completed.

[0050] After the test is completed, the equipment controls each cylinder to release the piston rod of the limit cylinder 45 to retract and the piston rod of the fixing cylinder 46 to extend in a preset sequence, thereby releasing the limit and clamping of the lamp plate 48. Then, the drive motor is started to send the two lamp plates 48 out from the second operation port 4, completing one test process.

[0051] It should be noted that the overall automatic control logic of this device is uniformly coordinated and implemented by a programmable logic controller (PLC). Based on the real-time feedback signals from each background suppression photoelectric sensor, the PLC accurately outputs control commands according to the preset program, which sequentially drives the various drive motors, limit cylinders, fixed cylinders, displacement motors, rotary motors and other actuators to perform orderly actions, completing the full-process automated control of lamp board conveying, limiting, clamping, insertion positioning, visual inspection and material discharge.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
