[0002] With the continuous improvement of technology, automated production is particularly important in the field of electronic product manufacturing. In the production process of electronic materials such as displays, the precise positioning of materials and quality inspection are the core links. The accuracy and efficiency of quality inspection determine the overall quality of automated production.

[0003] After the initial inspection, the products pass the manual re-inspection equipment. Products that pass the initial inspection will enter the next production line along the transport line. Products that fail the initial inspection (NG) will be picked up by a robot and placed on the re-inspection station for manual inspection. When there are no personnel on the manual re-inspection station, the robot will pick up the NG products and place them in the temporary storage mechanism for temporary storage. Traditional temporary storage mechanisms often have defects such as cumbersome product handling and small storage capacity. Therefore, there is a need for a temporary storage mechanism that can improve the efficiency of handling NG products. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tray temporary storage mechanism and a tray loading AOI detection and judgment device containing it, which can improve the picking and placing efficiency of NG products.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a pallet storage mechanism, comprising an outer frame and a storage rack capable of moving up and down relative to the outer frame. The storage rack includes several pallets for storing workpieces, each pallet including several crossbars. The storage rack includes a card plate with several guide grooves for supporting the crossbars. The outer frame is equipped with at least two push-pull components located on both sides of the storage rack for driving the pallets to move horizontally along the X-axis.

[0006] Optionally, the push-pull assembly includes a slide rail and a slide block that can move along the slide rail. The slide block is equipped with at least two telescopic cylinders, and the output end of the telescopic cylinder is connected to a recess. When the temporary storage rack moves downward, the recess is used to support the end of the crossbar.

[0007] Optionally, the push-pull assembly further includes a cooperating synchronous pulley and a synchronous belt, the synchronous belt being connected to the slide block, and one of the push-pull assemblies being connected to a power assembly, the power assembly being used to drive the synchronous pulley to rotate.

[0008] Optionally, a drive shaft is inserted into the outer frame, and both ends of the drive shaft are connected to synchronous pulleys at corresponding positions of the two push-pull components.

[0009] Optionally, the outer frame is equipped with a linear drive assembly, which includes a base fixedly connected to the outer frame, a motor mounted on the base, a guide rod connected to the output shaft of the motor, a bushing threadedly connected to the guide rod, and the bushing fixedly connected to the side wall of the temporary storage rack.

[0010] Optionally, the linear drive assembly further includes at least two guide rails and a slider that can move along the guide rails, the guide rails being fixedly connected to the outer frame and the slider being fixedly connected to the side wall of the temporary storage rack.

[0011] Optionally, the guide groove is L-shaped and is evenly spaced along the length of the card plate.

[0012] Optionally, there are two crossbars, located on the two sides of the tray respectively, and the length of the crossbars is greater than the length of the tray along the Y-axis. There are four pallets, located at the four corners of the tray respectively.

[0013] Optionally, a sensor for identifying the crossbar is provided inside the recess.

[0014] The tray loading AOI detection and re-judgment equipment includes the tray temporary storage mechanism.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. By setting several crossbars on both sides of the pallet and setting a recess at the output end of the telescopic cylinder, the linear drive assembly lowers the height of the temporary storage rack, so that the recess lifts the crossbars and the pallet is removed from the temporary storage rack. Then, the push-pull mechanism moves the telescopic cylinder and the pallet outward at the same time, so that the pallet extends out of the temporary storage rack, making it convenient for the robot to pick up and put in NG products. Afterward, the push-pull mechanism resets the telescopic cylinder and the pallet. The whole picking and putting process is convenient and fast.

[0016] 2. Multiple guide slots are densely arranged on the pallet. The height of the temporary storage rack is adjusted by a linear drive component. The push-pull component is used to push and pull the pallets of different layers, which can be precisely controlled. The picking and putting of pallets between different layers does not interfere with each other. The operation is convenient and can increase the storage capacity of the temporary storage rack.

[0023] like Figure 1 As shown, the extension direction of the tray 3 is the X-axis direction, the length direction of the crossbar 301 is the Y-axis direction, the push-pull assembly 5 of the tray 3 is installed on the horizontal plates on both sides of the outer frame 1, the linear drive assembly 6 is located between the two push-pull assemblies 5 in the middle position, the back plate of the temporary storage rack 2 is fixedly connected to the linear drive assembly 6, the temporary storage rack 2 can store 20-50 trays 3, the crossbar 301 located inside the tray 3 is restricted to move inside the temporary storage rack 2, and the crossbar 301 located outside the tray 3 can extend outside the temporary storage rack 2.

[0024] Example 2 This embodiment provides a tray storage mechanism, which differs from the first embodiment in that the push-pull assembly 5 includes a slide rail 501 and a slide block 502 that can move along the slide rail 501. The slide block 502 is equipped with at least two telescopic cylinders 503. The output end of the telescopic cylinder 503 is connected to a recess 504. When the storage rack 2 moves downward, the recess 504 is used to support the end of the crossbar 301.

[0025] The push-pull assembly 5 also includes a synchronous pulley 505 and a synchronous belt 506 that cooperate with each other. The synchronous belt 506 is connected to the slide 502. One of the push-pull assemblies 5 is connected to a power assembly 7, which is used to drive the synchronous pulley 505 to rotate.

[0026] A drive shaft 8 is inserted into the body of the outer frame 1. Both ends of the drive shaft 8 are connected to the synchronous pulleys 505 at corresponding positions of the two push-pull components 5.

[0027] When the telescopic cylinder 503 extends the recess 504, the recess 504 is positioned to support the end of the crossbar 301. When the telescopic cylinder 503 retracts the recess 504, the recess 504 is positioned to not interfere with the lifting and lowering of the temporary storage rack 2. The power assembly 7 is powered by a conventional motor, which transmits power to the output shaft via a gearbox, thereby driving the synchronous pulley 505 to rotate. Each push-pull assembly 5 has two synchronous pulleys 505, and a synchronous belt 506 connects the two synchronous pulleys 505. Multiple connection holes are provided on the back of the outer frame 1 along the Y-axis direction.

At this time, the recess 504 is located at the end of the crossbar 301 corresponding to the specific height. Then, the starter motor 602 drives the temporary storage rack 2 to descend a short distance until the crossbar 301 is lifted by the recess 504 and the height of the crossbar 301 is flush with the entrance end of the guide groove 202. Then, the power component 7 drives the telescopic cylinder 503 to move outward, thereby driving the tray 3 to extend, realizing the picking and placing of the workpiece 4. After that, the tray 3 is retracted in sequence, the temporary storage rack 2 rises until the tray 3 is lifted again, and the telescopic cylinder 503 retracts, completing the entire picking and placing process.
