[0059] (2) The pushing device pushes the measuring ruler 510 to move, and pushes the measuring ruler 510 to the top of the lamp holder. Then, the first lifting device controls the height of the pushing device and the measuring ruler 510 so that the measuring ruler 510 corresponds to the position of the lamp holder. Then, the measuring ruler 510 is used to measure the size of the lamp holder for the first time.

[0060] (3) After the first inspection is completed, the measuring ruler 510 is first controlled to rise by the first lifting device, and then the lamp holder inspection platform 10 is rotated by the rotating mechanism 40 so that the direction of the lamp holder changes. Then, the first lifting device controls the measuring ruler 510 to descend to inspect the size of the lamp holder again.

[0061] (4) After the second detection is completed, the first lifting device controls the measuring ruler 510 to rise, the pushing device retracts the measuring ruler 510, and pushes the size detection mechanism 50 away from the detection position, and the rotating mechanism 40 rotates in the opposite direction to return the lamp holder to the initial state;

[0062] Step 3: Hole position and diameter detection

[0063] (1) Pushing the hole position and aperture detection mechanism 60 to move to the detection position, and detecting the position of the lamp holder mounting hole and the size of the mounting hole diameter by the hole position and aperture detection mechanism 60;

[0064] (2) The hole position and aperture detection mechanism 60 is provided with a second lifting device, and an aperture detection device 610 is installed on the second lifting device. A plurality of aperture detection devices 610 are installed, and the aperture detection devices 610 are opposite to the mounting hole of the lamp holder. The aperture detection device 610 is controlled to descend by the second lifting device, and the aperture detection device 610 is used to detect the aperture size of the mounting hole;

[0065] (3) After the detection is completed, the second lifting device rises and then pushes the hole position and aperture detection mechanism 60 away from the detection position;

[0066] Step 4: Lamp holder flatness inspection

[0067] (1) The flatness of the lamp holder is detected by the flatness detection mechanism 70. The flatness detection mechanism 70 is provided with a third lifting device. The third lifting device is connected with a leveling member 78. The leveling member 78 is parallel to the lamp holder. The leveling member 78 is controlled to rise and fall by the third lifting device. The leveling member 78 abuts against the lamp holder so that the lamp holder is in a horizontal state. A pressing pin 15 is installed in the lamp holder detection platform 10. The pressing pin 15 is connected with a sensor. The sensor senses whether the pressing pin 15 is in contact with the lamp holder to detect whether the lamp holder is flat.

[0068] (2) After the detection is completed, the leveling member 78 is controlled by the third lifting device to return to the initial position.

[0069] The present invention first installs the lamp holder in the lamp holder detection platform 10 through the above method steps, and limits the lamp holder to the center through the centering clamping mechanism 20, then detects the size of the lamp holder through the size detection mechanism 50, and then detects the position of the lamp holder mounting hole and the size of the mounting hole diameter through the hole position and aperture detection mechanism 60, and finally detects the flatness of the lamp holder through the flatness detection mechanism 70, so as to realize fast and accurate detection of the size of the lamp holder, the position of the mounting hole, the diameter of the mounting hole and the flatness of the lamp holder.

[0070] like Figure 4As shown, the moving mechanism 30 includes a first moving rail 31, a first driving motor 32, a first moving block 33 and a moving platform 34. The moving platform 34 is fixed on the first moving block 33. The first moving block 33 is slidably installed on the first moving rail 31. The first moving rail 31 is fixed on the workbench 16. The first sliding block moves along the first moving rail 31. The first driving motor 32 is installed with a first threaded rod 35. The moving platform 34 is provided with a connecting portion 36. The first threaded rod 35 penetrates the connecting portion 36. The first driving motor 32 drives the first threaded rod 35 to rotate and drive the moving platform 34 to move. First limit blocks 37 are installed at both ends of the first moving rail 31 to limit the moving distance of the moving platform 34 to prevent the moving platform 34 from leaving the first moving rail 31. The first threaded rod 35 is driven to rotate by the forward and reverse rotation of the first driving motor 32 to drive the moving platform 34 to reciprocate along the first moving rail 31.

[0071] In the present invention, a moving mechanism 30 is provided to control the movement of the lamp holder detection platform 10. The moving mechanism 30 drives the lamp holder detection platform 10 to the side of the workbench 16, so that the staff can limit the lamp holder in the lamp holder detection platform 10, and then drive the lamp holder detection platform 10 to the detection position through the moving mechanism 30 to ensure the accuracy of the lamp holder detection.

[0072] like Figure 6 and Figure 7 As shown, the rotating mechanism 40 includes a rotating platform 41, a rotating shaft 42, a bearing seat 43, a limiting bearing 44, a rotating gear 45, a pushing rack 46 and a first pushing cylinder 47. The limiting bearing 44 is installed in the bearing seat 43, the rotating shaft 42 is rotatably installed in the limiting bearing 44, the rotating gear 45 is fixed on the rotating shaft 42, and the rotating gear 45 rotates to drive the rotating shaft 42 to rotate synchronously. The first pushing cylinder 47 is fixed on the fixed seat 48, and the fixed seat 48 is provided with a limiting groove 49. The pushing rack 46 is limited in the limiting groove 49. The limiting groove 49 plays a limiting guiding role in the movement of the pushing gear, and one end of the pushing rack 46 is connected to the limiting groove 49. The first pushing cylinder 47 is connected, and the first pushing cylinder 47 pushes the pushing rack 46 to move back and forth, and the pushing rack 46 is engaged with the rotating gear 45. The rotating platform 41 is fixed on the rotating shaft 42 and rotates synchronously with the rotating shaft 42. The movement of the pushing rack 46 is controlled by the first pushing cylinder 47. Since the pushing rack 46 is engaged with the rotating gear 45, the rotating gear 45 is driven to rotate during the movement of the pushing rack 46, and the rotating platform 41 is driven to rotate. Since the lamp holder detection platform 10 is installed on the rotating platform 41 through the supporting column 11, the lamp holder detection platform 10 is driven to rotate. In this embodiment, the rotation angle of the rotating platform 41 is 90°.

[0073] The setting of the rotating mechanism 40 facilitates the rotation of the lamp holder inspection platform 10. After the size detection mechanism 50 measures the size of the lamp holder, the rotating mechanism 40 is rotated to reverse the direction of the lamp holder, and the size of the lamp holder is measured again by the size detection mechanism 50, thereby improving the accuracy of the lamp holder size measurement.

[0074] The lamp holder inspection platform 10 is provided with a mounting groove 12 for mounting the lamp holder. The structure of the mounting groove 12 is not limited in the present invention. The lamp holder inspection platform 10 can be replaced according to lamp holders of different shapes so that the mounting groove 12 and the lamp holder have the same shape.

[0075] The centering clamping mechanism 20 is installed on the bottom surface of the lamp holder detection platform 10, and the centering clamping mechanism 20 includes a transverse centering mechanism and a longitudinal centering mechanism. The transverse centering mechanism and the longitudinal centering mechanism are vertically arranged. The lamp holder is laterally centered by the transverse centering mechanism, and is longitudinally centered by the longitudinal centering mechanism. Under the joint action of the transverse centering mechanism and the longitudinal centering mechanism, the lamp holder is centered in the mounting groove 12 to ensure that the subsequent aperture vacancy detection mechanism can detect the position and aperture of the lamp holder mounting hole. The transverse centering mechanism and the longitudinal centering mechanism have the same structure, both including a two-way cylinder 21 and a clamp 22. The two-way cylinder 21 is connected to the clamp 22. The lamp holder detection platform 10 is provided with a through groove 14. The clamp 22 passes through the through groove 14 and is limited in the through groove 14. The clamp 22 is driven to move along the through groove 14 by the extension and retraction of the two-way cylinder 21, and the lamp holder is limited and fixed by the clamp 22 to prevent the lamp holder from shifting.

[0076] like Figure 8 As shown, the size detection mechanism 50 includes a second moving rail 51, a second moving block 52, a mounting platform 53, a first lifting device and a pushing device. The mounting platform 53 is mounted on the second moving block 52, and the second moving block 52 is slidably mounted on the second moving rail 51. The second moving rail 51 is fixedly mounted on the workbench 16. The second moving rail 51 is vertically arranged with the first moving rail 31. The first lifting device and the pushing device are mounted on the mounting platform 53. The second moving block 52 drives the mounting platform 53 to move along the second moving rail 51, thereby driving the first lifting device and the pushing device to move. Second limit blocks 54 are installed at both ends of the second moving rail 51. The second limit blocks 54 prevent the mounting platform 53 from leaving the second moving rail 51.

[0077] Through the above mechanism design, when the size of the lamp holder needs to be measured, the size detection mechanism 50 is pushed to move along the second movable track 51 to the detection position, and is pushed away after the detection is completed to avoid subsequent detection. The structure is simple and easy to operate.

[0078] The first lifting device includes a lifting platform 55, a guide rod 56, a second drive motor 57 and a second threaded rod 58. The second drive motor 57 is connected to the second threaded rod 58. The lifting platform 55 is installed on the second threaded rod 58. The second drive motor 57 drives the second threaded rod 58 to drive the lifting platform 55 to move up and down. The guide rod 56 is fixed on the mounting platform 53. The guide rod 56 runs through the lifting platform 55. The lifting and lowering of the lifting platform 55 is guided and stabilized by the setting of the guide rod 56.

[0079] The pushing device is installed on the lifting platform 55 . The pushing device adopts a hydraulic cylinder 59 . The output end of the hydraulic cylinder 59 is connected to a measuring ruler 510 .

[0080] When the size detection mechanism 50 detects the size of the lamp holder, it first pushes the installation platform 53 to move, pushes the size detection mechanism 50 to the detection position, and then the hydraulic cylinder 59 pushes out the measuring ruler 510. At this time, the measuring ruler 510 is located above the lamp holder, and then the measuring ruler 510 is controlled to descend through the first lifting device to realize the size detection of the lamp holder.

[0081] like Fig. 9 As shown, the hole position and aperture detection mechanism 60 includes a third moving rail 61, a third moving block 62, a mounting bracket 63 and a second lifting device, an alignment template 69 and an aperture detection device 610.

The second lifting device is mounted on the mounting bracket 63. The alignment template 69 is connected to the second lifting device. The aperture detection device 610 is mounted on the alignment template 69. Third limit blocks 64 are installed at both ends of the third moving rail 61. The third limit blocks 64 prevent the mounting bracket 63 from leaving the third moving rail 61.

[0082] In the present invention, the aperture detection device 610 belongs to the prior art. The aperture detection device 610 is used to measure the size of the aperture, so it is not elaborated here. There are multiple aperture detection devices 610 installed, and each aperture detects the aperture of a mounting hole of the lamp holder separately. Multiple aperture detection devices 610 are installed on the alignment template 69 according to the set position of the lamp holder mounting hole. The shape of the alignment template 69 is not set and is synchronized with the lamp holder structure. After the alignment template 69 is located above the lamp holder, the aperture detection device 610 can detect the aperture to determine whether the position of the mounting hole is accurate.

[0083] The second lifting device includes a second pushing cylinder 65, a mounting seat 66, a first stable rail 67 and a first stable slider 68. The second pushing cylinder 65 is installed on the mounting bracket 63. The second pushing cylinder 65 is connected to the mounting seat 66. The first stable slider 68 is fixedly installed on the mounting seat 66. The first stable rail 67 is fixed on the mounting bracket 63. The first stable slider 68 is slidably set on the first stable rail 67. The alignment template 69 is installed on the mounting seat 66. The mounting seat 66 is pushed up and down by the second pushing cylinder 65. The first stable slider 68 is designed along the first stable rail 67 to increase the stability of the up and down movement of the mounting seat 66.

[0084] A detection slot 13 is provided in the mounting slot 12 of the lamp holder detection platform 10, and a sensor and a pressing pin 15 are installed in the detection slot 13. The top of the pressing pin 15 is higher than the detection slot 13. There are multiple pressing pins 15. When not being detected, the tops of the multiple pressing pins 15 are on the same horizontal plane.

[0085] like Fig.10 As shown, the flatness detection mechanism 70 includes a fixed bracket 71, a third lifting device, a third pushing cylinder 77 and a leveling member 78. The third lifting device is installed on the fixed bracket 71, the third pushing cylinder 77 is installed on the third lifting device, and the leveling member 78 is connected to the third pushing cylinder 77. The third lifting device controls the lifting and lowering of the third pushing cylinder 77 and the leveling member 78. When the leveling member 78 is located above the lamp holder, the third pushing cylinder 77 pushes the leveling member 78 to move, and the leveling member 78 squeezes the lamp holder so that the side of the lamp holder that is against the leveling member 78 is in a horizontal state. At this time, the other side of the lamp holder is located in the installation groove 12 and contacts with the pressing pin 15 in the detection groove 13. The sensor senses the numerical value of each pressing pin 15 in contact with the lamp holder to judge the flatness of the surface of the lamp holder.

[0086] The third lifting device includes a third driving motor 72, a third threaded rod 73, a lifting seat 74, a second stable rail 75 and a second stable slider 76. The third driving motor 72 is connected to the third threaded rod 73. The lifting seat 74 is installed on the third threaded rod 73. The third driving motor 72 drives the third threaded rod 73 to rotate, thereby driving the lifting seat 74 to move up and down. The second stable rail 75 is fixed on the fixed bracket 71. The second stable slider 76 is fixed on the lifting seat 74. The second stable slider 76 is slidably installed on the second stable rail 75 and slides along the second stable rail 75. The design of the second stable slider 76 and the second stable rail 75 increases the stability of the lifting of the lifting seat 74. The third pushing cylinder 77 is installed on the lifting seat 74. First, the leveling member 78 is controlled to move up and down by the third lifting device to adjust the distance between the leveling member 78 and the lamp holder.
