Description

Technical Field

[0001] This utility model relates to the field of concentricity detection technology, specifically an automated electronic component concentricity detection device. Background Technology

[0002] Electronic component concentricity testing equipment is an automated instrument used to precisely measure the degree of deviation between the axes of different cylindrical surfaces inside components (such as connector pins, sensor probes, lens sleeves, connecting terminals, etc.). Its core is to clamp the workpiece through a high-precision rotating spindle and use a laser displacement sensor or vision imaging system to simultaneously collect contour data of different cross sections. After calculation and analysis by a special algorithm, it quickly determines whether the concentricity error is within the allowable tolerance range. It is a key quality inspection equipment to ensure the assembly accuracy of high-end electronic components.

[0003] Most existing concentricity testing equipment adopts a single-station design, requiring loading, testing, and unloading to be performed sequentially, making synchronous operation impossible. This results in long idle waiting times, low testing efficiency, difficulty in adapting to batch production needs, and unintuitive feedback of test results. Manual checks of industrial computer data are required to determine whether the equipment is qualified or not, and the lack of corresponding indicator lights at each station increases labor costs and judgment errors.

[0004] Based on this, an automated electronic component concentricity testing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-4 As shown, an automated electronic component concentricity testing device includes a workbench 1, a mounting groove 2 is provided on the top of the workbench 1, a testing mechanism 5 is provided on the top of the workbench 1 and on one side of the mounting groove 2, and casters 8 are provided at the four corners of the bottom of the workbench 1.

[0028] The mounting slot 2 is equipped with a drive mechanism 3 inside, and two clamping mechanisms 4 are provided outside the drive mechanism 3.

[0029] In this embodiment, a dual clamping mechanism 4 is used in an alternating operation design, which, together with the drive mechanism 3, enables simultaneous feeding and inspection, significantly reducing waiting time and improving inspection efficiency to meet batch inspection requirements. The clamping component 48 is driven by the electric cylinder 411, which, in conjunction with the first positioning groove 44 and the second positioning groove 49, can stably clamp the connector interface terminals, reducing inspection deviation. The indicator light 45 can intuitively display the inspection results, making it convenient for staff to quickly distinguish between qualified and unqualified products and reducing human judgment errors. The inspection mechanism 5 can flexibly adjust the height of the vision inspection module 53 and the supplementary light 55. The supplementary light 55 ensures stable lighting in the inspection environment, improving the accuracy and reliability of vision inspection.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the driving mechanism 3 includes a lead screw 31, which is rotatably mounted inside the mounting slot 2 via bearings. A motor 32 is fixedly mounted on one side of the worktable 1. The lead screw 31 is driven by the motor 32, which drives the lead screw 31 in the mounting slot 2 to rotate. The lead screw 31 drives two externally threaded movable seats 41 to move, moving one of the clamping mechanisms 4 directly below the detection mechanism 5, while the other clamping mechanism 4 moves to one end of the worktable 1. At this time, the clamping mechanism 4 located at one end can be loaded, while the clamping mechanism 4 located directly below the detection mechanism 5 is simultaneously detected, realizing simultaneous loading and detection, and improving detection efficiency.

[0031] In one embodiment, such as Figure 1 and Figure 3As shown, the clamping mechanism 4 includes a movable base 41, which is threaded to the outside of the lead screw 31. A mounting plate 42 is fixedly installed on the top of the movable base 41. A fixing block 43 is provided on one side of the top of the mounting plate 42. Fixing members 46 are provided on both outer sides of the fixing block 43. Sliding members 47 are slidably installed through one side of each of the two fixing members 46. Clamping members 48 are provided at one end of each of the two sliding members 47. Multiple first positioning grooves 44 are equidistantly opened on the top of the fixing block 43. Multiple second positioning grooves 49 are equidistantly opened on the top of the clamping members 48. Indicator lights 45 are equidistantly embedded in the top of the fixing block 43. Two fixing plates 410 are symmetrically arranged on the top of the mounting plate 42. Electric cylinders 411 are fixedly installed on one side of the fixed plate 410. One end of each of the two electric cylinders 411 is fixedly installed with two sliding members 47. The electric cylinders 411 extend and drive the sliding members 47 to slide along the fixed member 46, thereby moving the clamping member 48 away from the fixed block 43. At this time, the terminal to be tested is placed into the first positioning groove 44 on the top of the fixed block 43. Then the electric cylinders 411 retract, driving the sliding member 47 and the clamping member 48 closer to the fixed block 43. The second positioning groove 49 on the top of the clamping member 48 cooperates with the first positioning groove 44 to stably clamp and fix the terminal. If the offset is within the threshold range, it is judged as qualified, and the indicator light 45 of the corresponding clamping mechanism 4 lights up green. If the offset exceeds the threshold, it is judged as unqualified, and the indicator light 45 lights up red.

[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, the detection mechanism 5 includes a slide bar 51, which is mounted on the top of the workbench 1. A first lifting frame 52 and a second lifting frame 54 are slidably mounted on the outside of the slide bar 51. A vision inspection module 53 is provided at one end of the first lifting frame 52, and a supplementary light 55 is provided at one end of the second lifting frame 54. Bolts 56 are provided on the outside of both the first lifting frame 52 and the second lifting frame 54. The supplementary light 55 provides a uniform and stable light source to eliminate reflections or shadows on the terminal surface, ensuring that the vision inspection module 53 can clearly capture a two-dimensional image of the terminal. After the camera acquires an image from a specific angle, the image data is transmitted. The industrial computer 74 extracts the contour edges of key parts of the terminal through an edge detection algorithm, and then identifies the geometric center corresponding to these contours through algorithms such as Hough transform. The system uses the reference structure of the terminal as a reference to calculate the radial offset between the measured structure and the reference axis. This offset is the concentricity value. The industrial computer compares the calculation result with a preset qualified threshold. If the offset is within the threshold range, it is judged as qualified, and the indicator light 45 of the corresponding clamping mechanism 4 is controlled to light up green. If the offset exceeds the threshold, it is judged as unqualified, and the indicator light 45 lights up red, thereby completing the automated detection of the concentricity of the connector interface terminal.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, a mounting block 6 is fixedly installed on one side of the workbench 1. An adjustment mechanism 7 is provided on one side of the mounting block 6. The adjustment mechanism 7 includes a mounting base 71, which is fixedly installed on one side of the mounting block 6. A connecting rod 72 is rotatably mounted on the outside of the mounting base 71 via a pin. A mounting bracket 73 is rotatably mounted on one end of the connecting rod 72 via a pin. An industrial computer 74 is provided on the outside of the mounting bracket 73. The operator can adjust the angle of the industrial computer 74 to view data by rotating the connecting rod 72 and the mounting bracket 73 on the mounting base 71.

[0034] The above embodiment discloses an automated electronic component concentricity testing device, wherein the electric cylinder 411 extends to drive the sliding member 47 to slide along the fixed member 46, thereby moving the clamping member 48 away from the fixed block 43. At this time, the terminal to be tested is placed into the first positioning groove 44 on the top of the fixed block 43. Then the electric cylinder 411 retracts, driving the sliding member 47 and the clamping member 48 closer to the fixed block 43. The second positioning groove 49 on the top of the clamping member 48 cooperates with the first positioning groove 44 to stably clamp and fix the terminal.

[0035] Start the drive mechanism 3, and the motor 32 drives the lead screw 31 in the mounting slot 2 to rotate. The lead screw 31 drives the two movable seats 41 connected by external threads to move, moving one of the clamping mechanisms 4 directly below the detection mechanism 5, and the other clamping mechanism 4 to one end of the worktable 1. At this time, the clamping mechanism 4 located at one end can be loaded, while the clamping mechanism 4 located directly below the detection mechanism 5 can be detected simultaneously, realizing the simultaneous loading and detection, and improving detection efficiency.

[0036] Before testing, the heights of the first lifting frame 52 and the second lifting frame 54 can be adjusted using the slide bar 51. After loosening the bolt 56 and moving it to the appropriate position, tighten it to ensure that the vision inspection module 53 is aligned with the terminal below. At the same time, the supplementary light 55 is turned on to provide sufficient illumination. The vision inspection module 53 detects the concentricity of the interface terminals using the vision inspection principle and transmits the detection data to the industrial computer 74 via wires. After analyzing the data, the industrial computer 74 controls the indicator light 45 on the corresponding clamping mechanism 4 to display the results. The indicator light 45 of the qualified connector interface terminal lights up green, while that of the unqualified terminal lights up red. When a set of tests is completed, the drive mechanism 3 drives the two clamping mechanisms 4 to move again, moving the tested terminal to one end for unloading, and moving the other set of loaded terminals to the test position. The test operation is repeated in a cycle.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
