[0017] Figure 1 It is a front view of the present invention; Figure 2 for Figure 1 AA section view of the image (with the suction cup hidden); Figure 3 It is a top view of the present invention (the suction cup and the photoelectric sensor are hidden).

[0018] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings. Example

[0020] like Figure 1 — Figure 3 As shown, a storage and retrieval device for automobile door stampings includes two rows of symmetrically arranged main frames 12, conveyor belts 4 are provided in both rows of main frames 12, eight pallets 6 are symmetrically provided on two conveyor belts 4, and door stampings 5 ​​are sequentially placed on two symmetrically arranged pallets 6 of two conveyor belts 4. In actual application, the number of pallets 6 can be flexibly arranged according to the actual situation of the workshop and the size and weight of the door stampings 5. The pallet 6 is moved up or down by the rotation of the conveyor belt 4, and the door stampings 5 ​​can be placed on or removed from the pallet 6. The pallet 6 is made of flexible materials such as plastic / rubber to avoid damage to the door.

[0021] The upper and lower ends of the main frame 12 are respectively provided with an upper roller 3 and a lower roller 14 that cooperate with the conveyor belt 4, and the lower roller 14 is connected to a drive motor 13, and the drive motor 13 is installed on the motor bracket 10. The drive motor 13 can drive the conveyor belt 4 to rotate. In some embodiments, the upper roller 3 can also be connected to the motor.

[0022] The upper roller 3 and the lower roller 14 are both sprockets, and a conveyor chain that cooperates with the sprocket is arranged on the inner side of the conveyor belt 4. In some embodiments, the conveyor belt 4 can also be set as a conveyor chain, and the support plate 6 is directly arranged on the outer side of the conveyor chain. The arrangement of the sprocket can prevent the conveyor belt 4 from slipping, making the door storage and retrieval process more stable and reliable.

[0023] In addition, the rollers and conveyor belts can also be processed with a certain tension or surface structure of the contact surface to increase friction and ensure normal lifting of the door stamping parts without slipping. The upper roller 3 and the lower roller 14 are installed on the main frame 12 through bearings so that they can rotate smoothly.

[0024] A photoelectric sensor 1 for monitoring the position of the door stamping 5 is arranged above the main frame 12. When storing the door, ensure that the door it monitors is located on the lower level of the current pallet 6 (i.e., the distance between the door and the photoelectric sensor 1 meets the requirement), so that the door can be stored on the current pallet 6. When taking out the door, ensure that the door it monitors is located on the current pallet 6 (i.e., the distance between the door and the photoelectric sensor 1 meets the requirement), so that the door can be taken out smoothly.

[0025] A lifting plate 8 is also provided between the two rows of main frames 12, and a spring 9 is provided at the bottom of the lifting plate 8, and the spring 9 is provided on the base 11. The lifting plate 8 abuts against the bottommost support plate 6 under the action of the spring 9. The spring 9 plays a supporting role to prevent the conveyor belt 4 from slipping when there are many car doors placed in the device.

[0026] The bottom surface of the lowermost support plate 6 is provided with a gasket 7 in contact with the lifting plate 8. The gasket 7 is a steel sheet with relatively high hardness to enhance the wear resistance of the contact surface.

[0027] The cross section of the support plate 6 is triangular, trapezoidal or square. The spacing and size of the support plates 6 can be set according to the thickness and quality of different automobile door stamping parts, and it is necessary to ensure that two adjacent stamping parts do not contact each other during the stacking process. The support plate 6 and the conveyor belt 4 can be integrally formed or assembled together after being formed separately.

[0028] The bottommost pallet 6 is provided with a stopper (not shown) to prevent it from passing over the upper roller 3. A slot for the pallet 6 to enter can be provided on the inner side wall of the main frame 12, but a stopper should be provided on the bottommost pallet 6 to prevent it from entering the slot. During the process of storing and retrieving door panels, workers should generally avoid the bottommost pallet 6 passing over the upper roller 3 and entering the main frame 12, which may cause equipment failure. The setting of the stopper can prevent workers from operating incorrectly.

[0029] In addition, this embodiment also discloses a method for storing and retrieving automobile door stamping parts. Using the aforementioned storage and retrieval device, the storage method is as follows: S1, the conveyor belt 4 moves upward until, except for the bottommost pallet 6, the rest of the pallets 6 pass over the upper roller 3 and enter the main frame 12. At this time, the position of the bottommost pallet 6 can be detected by the photoelectric sensor 1. After the position is qualified, the door stamping part is adsorbed by the suction cup 2 and placed on the bottommost pallet 6; S2, the conveyor belt moves down, and the distance of the downward movement is the distance between two adjacent pallets 6. The starting time of the motor can be preset each time to ensure that the moving distance of the conveyor belt 4 meets the requirements each time it is started, until the pallet above the lowest pallet passes over the upper roller 3. At this time, the photoelectric sensor 1 can also detect the position of the current pallet 6 or the position of the door placed in S1 to ensure that the equipment is fault-free. The suction cup 2 absorbs the door stamping again and places it on the pallet; S3, repeat S2, and place the door stamping parts on the pallet in sequence; The removal method is as follows: S10, first use the photoelectric sensor 1 to detect the position of the top door, and after the position is correct, use the suction cup 2 to absorb the door stamping part and place it on the work station; S20, the conveyor belt moves upward, and the upward movement distance is consistent with the downward movement distance in the aforementioned S2, and the pallet 6 of the removed door stamping part passes over the upper roller 3 and enters the main frame 12. At this time, the photoelectric sensor 1 can also detect the position of the door on the current pallet 6 to ensure that the equipment is fault-free, and then the suction cup 2 is used again to remove the next door stamping part and place it on the work station; S30, repeat S20, and place the door stamping parts on the workstations in sequence.

[0030] It should be noted that in the aforementioned storage method, it is assumed that no car doors are placed in the current device. In actual use, those skilled in the art should understand that, according to different production plans of the workshop, the device can also realize the retrieval of car doors during the storage process, or the storage of car doors during the retrieval process. This process will not be described in detail.
