During specific work, when the lamp tube 100 falls into the rectangular pre-clamping frame 44 from the transportation platform 43, the two pins 110 at the two ends of the lamp tube 100 are uncertain in position distribution and have randomness, so that the positions of the two pins 110 at the two ends of the lamp tube 100 need to be adjusted before the arc-shaped clamping plate 489 completely clamps and fixes the lamp tube 100, when the clamping bar 485 is driven by the biaxial hydraulic cylinder 486 in this case to move, the elastic expansion plate 445 is driven to move synchronously, the expansion end of the elastic expansion plate 445 pushes the correction bar 442 to move towards the lamp tube 100, and further the correction bar 442 corrects the positions of the pins 110 through the arc-shaped groove 4421, so that the lamp tube 100 rotates in the rectangular pre-clamping frame 44, so that the positions of the two pins 110 at the two ends of the lamp tube 100 are corrected, and the pins are ensured to be distributed up and down, so that the pins smoothly pass through the through holes 354 of the clamping ring 351 and the clamping groove 353 of the clamping block 352; in this case, the rectangular block 4411 can limit the rotation of the correction bar 442, so that the correction bar 442 can only rotate to the vertical state, and the correction bar 442 is prevented from affecting the upward movement of the lamp 100, after the pins 110 of the lamp 100 are adjusted, the arc-shaped clamping plate 489 clamps and fixes the lamp 100, and then the screw 482 pushes the lifting bar 481 to move upward by external driving, so that the lamp 100 moves upward synchronously, and at this time, the elastic expansion plate 445 can be separated from the correction bar 442, so that the correction bar 442 smoothly returns to the initial position through the first spring 444.

Referring to fig. 4, 5 and 7, further, in order to ensure that the lamps 100 on the transportation platform 43 smoothly move into the rectangular pre-clamping frame 44 and simultaneously ensure that the lamps 100 on the transportation platform 43 are prevented from moving into the rectangular pre-clamping frame 44 when the lamps 100 are in the rectangular pre-clamping frame 44, a through hole is formed in the right end of the transportation platform 43, a partition block 432 is slidably arranged in the through hole, the right side of the partition block 432 is an inclined surface inclined downwards, an inverted T-shaped plate 433 is connected to the bottom of the partition block 432, a second spring 434 is connected between the left side of the horizontal section of the T-shaped plate 433 and the bottom of the transportation platform 43, and the right end of the horizontal section of the T-shaped plate 433 is in interference fit with a clamping strip 485 positioned on the left side of the rectangular pre-clamping frame 44.

When the lamp tube 100 in the rectangular pre-clamping frame 44 is clamped and pushed to the detection frame 1 by the clamping jacking unit 48, when the lead screw 482 drives the lifting bar 481 to move downwards, the double-shaft hydraulic cylinder 486 drives the clamping bar 485 to move towards the middle of the lifting bar 481 first, so that the clamping bar 485 can smoothly pass through the gap between the transportation platform 43 and the rectangular pre-clamping frame 44, after the clamping bar 485 moves downwards below the transportation platform 43, the double-shaft hydraulic cylinder 486 pushes the clamping bar 485 to move towards the end part of the lifting bar 481, so that the clamping bar 485 can move to the upper part of the right side of the horizontal section of the T-shaped plate 433, at the moment, the lead screw 482 continues to drive the clamping bar 485 to move downwards by the lifting bar 481, so that the clamping bar pushes the T-shaped plate 433 to synchronously move downwards to drive the separation blocks 432 to move downwards, when the upper ends of the separation blocks 432 move downwards into the through holes 485, the lamp tube 100 on the existing conveyer belt pushes the lamp tube 100 at the rightmost end of the transportation platform 43 to move rightmost to move rightwards, meanwhile, the double-shaft hydraulic cylinder 486 drives the clamping strip 485 to move towards the middle part of the lifting strip 481 so as to enable the clamping strip 485 to be separated from being in contact with the T-shaped plate 433, and the T-shaped plate 433 is pulled by the second spring 434 to drive the separating block 432 to move upwards, so that the lamp 100 on the transportation platform 43 is blocked and separated again, and the inclined surface at the right side of the dividing block 432 can push the lamp 100 that has passed over the dividing block 432, preventing the lamp 100 from staying at the gap between the transporting platform 43 and the rectangular pre-clamping frame 44, it should be noted that the gap between the transportation platform 43 and the rectangular pre-clamping frame 44 is smaller than the diameter of the lamp 100, so as to prevent the lamp 100 from directly falling into the gap, then the two-axis hydraulic cylinder 486 pushes the clamping bar 485 towards the end of the lifting bar 481, so that the lamp 100 can smoothly fall into the rectangular pre-clamping frame 44, and further, the subsequent correction, clamping and pushing of the lamp 100 are facilitated.

Referring to fig. 4, 5 and 7, in addition, in order to ensure that the lamp 100 moved into the rectangular pre-clamping frame 44 can rotate to adjust the angle of the pins 110, an arc seat 446 for placing the lamp 100 is disposed at the bottom of the rectangular pre-clamping frame 44, a plurality of auxiliary rollers 4461 are uniformly disposed on the arc surface of the arc seat 446, and elastic isolation layers (not shown) are disposed on the outer surface of the auxiliary rollers 4461 and the arc surface of the arc seat 446, and an elastic isolation layer (not shown) is disposed on the inner side wall of the rectangular pre-clamping frame 44.
