[0034] Specifically, the fully automatic detection equipment for projection lamps is installed in a darkroom, which provides a low stray light environment, isolates external light, ensures the irradiation of the light of the projection lamp 7, and reduces the influence of reflected light. The darkroom wall adopts a light-absorbing layer to greatly reduce the reflected light, so that the light distribution measurement of the projection lamp 7 is closer to the real state, which can ensure the accuracy of the detection result.

[0035] The tray 8 loaded with projection lamps 7 is manually stacked and placed on the lifting plate 412 of the loading mechanism 41 of the feeding mechanism 4. The lifting mechanism drives the lifting plate 412 to move the tray 8 upward to the loading station. The moving mechanism 5 clamps the projection lamp 7 and transfers the projection lamp 7 to the heat dissipation mechanism 63 of the focusing mechanism 6. The positioning mechanism 64 clamps and positions the body of the projection lamp 7. The heat dissipation mechanism 63 dissipates the PCBA board of the projection lamp 7. The rotating clamping mechanism 65 clamps the knob part of the projection lamp 7 and rotates the knob part of the projection lamp 7 to adjust the focal length. The torque sensor 66 detects the rotation torque value of the rotating clamping mechanism 65 to prevent excessive rotation. The first multi-axis robot 61 drives the projection lamp 7 to rotate to the projection direction, so that the light of the projection lamp 7 is projected on the screen 22 of the screen assembly 2, and the detection mechanism 3 detects the shape, clarity, uniformity, etc. of the projected image on the screen assembly 2. After the detection is completed, the material transfer mechanism 5 transfers the detected projection lamp 7 on the focusing mechanism 6 to the tray 8. When the multiple projection lamps 7 on the tray 8 are all detected, the conveying mechanism 43 of the feeding mechanism 4 drives the tray 8 to move to the unloading mechanism 42 for unloading operation. Among them, the first multi-axis robot 61 adopts a six-axis robot.

[0036] In the above structure, the rotary clamping mechanism 65 is used to realize the automatic focus adjustment of the projection lamp 7, and the detection mechanism 3 and the screen assembly 2 are used to realize the automatic detection of the projection lamp 7.

[0037] like Figure 2As shown, in one embodiment, the rotary clamping mechanism 65 of the projection lamp automatic detection device includes a rotary motor 651, an L-shaped rotating table 652, a first clamping claw cylinder 653 and two first clamping claws 654. The rotary motor 651 is installed at the bottom end of the connecting plate 62, the driving end of the rotary motor 651 is connected to one end of the L-shaped rotating table 652, one end of the L-shaped rotating table 652 is connected to the torque sensor 66, and the first clamping claw cylinder 653 is installed at the other end of the L-shaped rotating table 652. The driving end of the first clamping jaw cylinder 653 is connected to the two first clamping jaws 654 respectively. The two first clamping jaws 654 are respectively provided with a profiling clamping block 655. The first clamping jaw cylinder 653 is used to drive the profiling clamping blocks 655 on the two first clamping jaws 654 to clamp the knob of the projection lamp 7. The rotating motor 651 drives the L-shaped rotating table 652 to drive the first clamping jaw cylinder 653 and the knob of the projection lamp 7 to rotate. The torque sensor 66 detects the torque value of the L-shaped rotating table 652. After the positioning mechanism 64 clamps and positions the projection lamp 7 on the heat dissipation mechanism 63, the first clamping jaw cylinder 653 drives the profiling clamping blocks 655 of the two first clamping jaws 654 to clamp the knob of the projection lamp 7. The rotating motor 651 drives the L-shaped rotating table 652 to drive the first clamping jaw cylinder 653 and the knob of the projection lamp 7 to rotate. The knob rotates to adjust the focal length. The detection mechanism 3 detects the image projected by the projection lamp 7. This arrangement realizes automatic focus adjustment of the projection lamp 7 and improves the consistency of adjustment.

When the material transfer mechanism 5 places the projection lamp 7 on the heat dissipation mechanism 63, the second clamping claw cylinder 641 drives the two second clamping claws 642 to clamp and position the body of the projection lamp 7. This arrangement improves the positioning effect of the projection lamp 7 and ensures the accuracy of the focal length adjustment of the projection lamp 7.

[0039] like Figure 3 and Figure 4As shown, in one embodiment, the feeding mechanism 4 of the projection lamp fully automatic detection equipment includes a loading mechanism 41 for loading a tray 8 full of undetected projection lamps 7, a unloading mechanism 42 for unloading a tray 8 full of detected projection lamps 7, and a conveying mechanism 43 for conveying the tray 8 on the loading mechanism 41 to the unloading mechanism 42. The loading mechanism 41 and the unloading mechanism 42 have the same structure, and the unloading mechanism 42 is located on one side of the loading mechanism 41. The loading mechanism 41 includes a discharge rack 411 for guiding the tray 8, a lifting plate 412 for placing multiple trays 8, and a lifting mechanism for driving the lifting plate 412 to move up and down, the driving end of the lifting mechanism is connected to the lifting plate 412, and the lifting mechanism is used to drive the lifting plate 412 to drive multiple trays 8 to move up and down along the discharge rack 411. Multiple trays 8 loaded with undetected projection lamps 7 are manually stacked on the lifting plate 412 of the loading mechanism 41. The lifting mechanism drives the lifting plate 412 to move multiple trays 8 upward. When the top tray 8 moves to the specified position, the material transfer mechanism 5 sequentially transfers the projection lamps 7 on the tray 8 to the focusing mechanism 6 for focusing detection. After the detection of the projection lamp 7 is completed, the material transfer mechanism 5 places the projection lamp 7 on the original discharge position of the tray 8. After the detection of multiple projection lamps 7 on the tray 8 is completed, the conveying mechanism 43 drives the tray 8 to move horizontally to the lifting plate 412 of the unloading mechanism 42. The lifting mechanism of the unloading mechanism 42 drives the lifting plate 412 to move downward to discharge the tray 8 in turn. When the trays 8 on the lifting plate 412 of the unloading mechanism 42 are fully stacked, the trays 8 are manually unloaded.

The lifting mechanism of the loading mechanism 41 drives the lifting plate 412 to drive the tray 8 to move upward to the limit frame 433. When the projection lamps 7 on the tray 8 are all detected, the limit mechanism 434 limits the two ends of the tray 8. The linear module 432 drives the limit frame 433 and the limit mechanism 434 to drive the tray 8 to move horizontally to the lifting plate 412 of the unloading mechanism 42. The lifting mechanism of the unloading mechanism 42 drives the lifting plate 412 to drive the tray 8 to move downward. The linear module 432 drives the limit frame 433 and the limit mechanism 434 to move horizontally to the loading mechanism 41. This setting facilitates driving the tray 8 to move horizontally, ensuring that the tray 8 will not fall off during the movement process.

When the material transfer mechanism 5 clamps and moves the projection lamp 7 from the tray 8, the QR code of the projection lamp 7 is first moved to one side of the code scanning component 11. After the photoelectric sensor 122 detects the projection lamp 7, the code scanning gun 112 scans and records the QR code of the projection lamp 7.
