The present embodiment provides a re-inspection apparatus for a display device 1000, which can be adapted to a conveyor line downstream of a detection device of the display device 1000, so as to receive the display device 1000 that has been marked as a defective product or a non-defective product after being detected by the detection device, to directly output the defective display device 1000, and to re-inspect the defective display device 1000, and to return the display device 1000 that has been subjected to the re-inspection to output.

Referring to fig. 1, the review apparatus includes a holding mechanism 1, a transferring mechanism 2, a buffer mechanism 3, and a review mechanism 4 for reviewing a defective display device 1000, wherein the holding mechanism 1 is capable of receiving and conveying the display device 1000 and has a first station and a second station; the first station corresponds to the transfer mechanism 2 so as to output a defective display device 1000 to the transfer mechanism 2; the second station is for outputting a qualified display device 1000. The transfer mechanism 2 is used for transporting the display device (1000) among the handling mechanism 1, the buffer mechanism 3 and the reinspection mechanism 4, for example, transporting the defective display device 1000 from the first station to the buffer mechanism 3, and transporting the qualified display device 1000 from the reinspection mechanism 4 to the handling mechanism 1. The buffer mechanism 3 is used for storing the defective display device 1000 and outputting the stored defective display device 1000, so that the rechecking mechanism 4 rechecks the defective display device 1000.

With the above structure, the handling mechanism 1 receives the display device 1000 transferred from the upstream transfer line, and distributes the qualified display device 1000 to the second station to be transferred, stored or transferred to the next processing station. The defective display device 1000 is distributed to the first station by the handling mechanism 1, so that the transfer mechanism 2 can transfer the defective product to the buffer mechanism 3, and the re-inspection mechanism 4 can receive the defective product output by the buffer mechanism 3 through manual work or transfer equipment and then re-inspect the defective product.

Because the appearance and display performance of the display device 1000 needs to be rechecked through the steps of image acquisition, image recognition, result judgment and the like, the rechecking efficiency of the rechecking mechanism 4 at the downstream of the cache mechanism 3 cannot be matched with the input efficiency of the display device 1000 input by the upstream moving and carrying mechanism 2, and the cache mechanism 3 can receive and store the display device 1000 to be rechecked, so that the slow slowing of the working beat of the whole rechecking device or an upstream conveying line due to the slow rechecking efficiency is avoided, and the display device 1000 is prevented from being detained on the conveying line. In other embodiments, the caching mechanism 3 can also be applied to other production links, such as stock for production of the semi-finished display device 1000, blanking for a production line of the finished display device 1000, and the like.

In order to be adaptable to trays 7 of different sizes and facilitate unloading of fully loaded trays 7, the bracket 321 may include a cross arm 3211 and a pair of supporting arms 3212 slidably disposed on the cross arm 3211, and the pair of supporting arms 3212 may slide toward or away from each other to support or release the trays 7 stacked on the pair of supporting arms 3212.

Specifically, as shown in fig. 9, a pair of support arms 3212 may be screwed to a pair of screw rods 3213 that are connected to each other and have opposite threads, and the pair of support arms 3212 is slidably connected to the cross arm 3211, so that the pair of support arms 3212 can slide toward or away from each other by driving the screw rods 3213 to rotate forward or backward.

Optionally, a block 3214 for placing the tray 7 is adjustably installed on the bracket arm 3212, and the block 3214 can be in lap joint with the edge of the tray 7. For example, the block 3214 may be lockably slidably connected to the arm 3212, and the arm 3212 may be further adapted to carry trays 7 with different lengths and widths by adjusting the installation position of the block 3214.

Referring to fig. 7 in conjunction with fig. 10, 11 and 12, in the present embodiment, the tray part 31 includes a pair of spaced conveyor belts 311, a supporting plate 312, a lifting seat 313 and a telescopic arm 314. The pair of conveyor belts 311 can convey the empty trays 7 one by one downstream thereof. The pallet 312 is disposed between the pair of conveyor belts 311. The output end of the lifting seat 313 is fixedly connected with the supporting plate 312 so as to drive the supporting plate 312 to lift. The output end of the telescopic arm 314 is fixedly connected with the lifting seat 313 so as to drive the lifting seat 313 to drive the supporting plate 312 to move between the pair of supporting arms 3212 and the pair of conveying belts 311 in a reciprocating manner.

During the tray separation operation, the conveyor belt 311 conveys the empty tray 7 to the downstream, so that the tray 7 is conveyed to the position above the supporting plate 312, the lifting seat 313 lifts the supporting plate 312 to enable the supporting plate 312 to be lifted away from the conveyor belt 311, then the telescopic arm 314 extends to drive the lifting seat 313 to drive the supporting plate 312 to move towards the direction of the bracket, so that the tray 7 is positioned above the pair of supporting arms 3212, the tray 7 is arranged between the pair of supporting arms 3212 in the descending and resetting process of the lifting seat 313, and the telescopic arm 314 retracts and resets. It can be understood that the width of the supporting plate 312 is smaller than the distance between the pair of supporting arms 3212, and when the supporting plate 312 is lifted by the lifting base 313, the height of the upper surface of the supporting plate 312 is higher than the height of the supporting arms 3212.

In this embodiment, the tray dividing section 31 may further include a loading unit that can feed the empty trays 7 to the pair of conveyors 311 one by one, so that the tray dividing section 31 can store the empty trays 7 and can perform tray dividing operation accurately and timely after the full trays 7 on the carriers 321 are unloaded.

Referring to fig. 11, the loading unit includes tray dividing assemblies 315 respectively disposed at both sides of the upstream sections of the pair of conveyor belts 311, and the tray dividing assemblies 315 include a clamp plate 3151, a first cylinder 3152, and a second cylinder 3153. The clamp plate 3151 extends in the vertical direction and parallel to the extending direction of the conveyor belt 311, and the clamp plate 3151 is provided with a latch 3154 extending toward the conveyor belt 311. The output end of the first cylinder 3152 is fixedly connected with the clamping plate 3151 so as to drive the clamping plate 3151 to lift. The output end of the second cylinder 3153 is fixedly connected to the first cylinder 3152, so as to drive the first cylinder 3152 to drive the clamp plate 3151 to move towards or away from the conveyor 311 in a reciprocating manner.

Therefore, the empty tray loading operation of loading the tray 7 by the tray part 31 into the transfer part 32 one by one may be performed by:

the empty trays 7 stacked are placed to the tray part 31;

subsequently, after lifting the remaining trays 7 except for the lowermost tray 7 by the tray sorting unit 315, the conveyor 311 conveys the lowermost tray 7 to the transfer section 32.

Specifically, the process of "lifting the other trays 7 except the lowermost tray 7" may be that the output end of the pair of second air cylinders 3153 extends to drive the first air cylinder 3152 and the clamp plate 3151 to move toward the direction of the conveyor belt 311, so that the latch 3154 is just clamped on the edge of the lowermost penultimate tray 7 in the stacked trays 7, and then the output end of the first air cylinder 3152 extends to drive the clamp plate 3151 to lift upward, so that the other trays 7 except the lowermost tray 7 are lifted off the conveyor belt 311, and the conveyor belt 311 can convey an empty tray 7 to the transfer part 32.

Optionally, a pair of latches 3154 are positionally adjustably secured to the clamp plate 3151 to enable mating with different sized trays 7.

In order to prevent the stacked empty trays 7 from overturning during the lifting or lowering of the stacked empty trays 7, the racking portion 31 further comprises a shaping plate 316 fixedly connected to the output end of the second cylinder 3153, the shaping plate 316 comprising a first shaping plate 3161 and a second shaping plate 3162, the first shaping plate 3161 having a first shaping surface coplanar with the surface of the clamping plate 3151 facing the conveyor 311; the second reshaping piece 3162 extends toward the conveyor 311, and has a second reshaping surface extending in the vertical direction and perpendicular to the extending direction of the conveyor 311, and the lower end of the second reshaping piece 3162 is higher than or equal to the height position of the latch 3154. So that the shaping plate 316 can move synchronously with the clamping plate 3151 when the second cylinder 3153 drives the clamping plate 3151 to move in the direction of the conveyor 311, so that the first shaping sheet 3161 and the second shaping sheet 3162 can abut against both edges of the stacked trays 7, respectively.

In this embodiment, the buffer part 33 may be a conveying device, such as a conveying belt, a conveying roller belt, etc., located below the sub-tray part 31. When the buffer part 33 is not fully loaded, the operation is suspended to gradually stack the trays 7 loaded thereon, and when the buffer part 33 is fully loaded, the operation outputs the stacked fully loaded trays 7, so that the display device 1000 stored in the tray 7 is rechecked after the tray 7 is taken out by a transfer device or a human.

Therefore, the method for caching the operation is as follows:

first, the tray part 31 carries the tray 7 piece by piece to the transfer part 32, and stores the buffer material (i.e., the display device 1000) in the tray 7 carried by the transfer part 32.

Subsequently, after the trays 7 carried by the transfer section 32 are fully loaded, the transfer section 32 is lowered to unload the trays 7 to the buffer section 33 (when the buffer section 33 is empty) or the trays 7 carried by the buffer section 33 (when the buffer section 33 carries the trays 7).

After the buffer portion 33 is fully loaded, the stacked tray 7 buffered therein is output.
