The top of the guide rail 163 is provided with a sliding groove 165 for the end of the guide roller 164 to slide. The bottom of the receiving rail 161 is provided with a second walking wheel 166. When the transfer trolley 15 enters the stock bin body 1, the second walking wheel 166 is received on the receiving rail 161.

[0036] When the transfer trolley 15 enters the stock bin body 1, the first walking wheel 153 enters the stock bin body 1 first. At this time, the guide roller 164 is directly opposite the guide rail 163. During the process of the transfer trolley 15 entering the stock bin body 1, the guide roller 164 enters the sliding groove 165 on the guide rail 163 and translates along the guide rail 163 to guide the translation of the transfer trolley 15, so as to conveniently drive the material plate 20 into the feeding area 3.

[0037] With reference to Figure 3 , Figure 10 and Figure 11 , when the material plate 20 in the feeding area 3 is transferred to the blank area 4, the transfer tray 61 fixes and receives the lowermost material plate 20, and then drives the transfer tray 61 to move through the first motor 622 and the second motor 631 to transfer the material plate 20 to the blank area 4. However, the load of the transfer tray 61 is large during this process, which easily causes the curved end of the transfer tray 61 to be suspended. Therefore, in the embodiment of the present application, the bottom of the transfer tray 61 is provided with an inclined support 17 which spans the corners of the transfer tray 61 to support the transfer tray 61. The application further comprises an avoiding piece which is used to accommodate the inclined support 17 in the bottom of the frame of the transfer tray 61 to avoid the material plate 20 when the transfer tray 61 sleeves the material plate 20. When the transfer tray 61 drives the material plate 20 to transfer, the inclined support 17 spans the corners of the transfer tray 61 to support the corners of the inclined support 17, so as to improve the anti-deformation ability of the transfer tray 61. Under the action of the avoiding piece, the transfer tray 61 conveniently passes through the material plate 20 and falls to the bottom of the stock bin body 1, so as to conveniently transfer the material plate 20 by the transfer tray 61.

[0038] Referring to Figure 3 , Figure 10 and Figure 11 , in the embodiment of the application, the inclined support 17 comprises two support plates 171 hingedly connected to each other, and the other ends of the two support plates 171 are hingedly connected to the bottom of the transfer tray 61. The hinged end of one support plate 171 is fixedly arranged at the bottom of the transfer tray 61, and the hinged end of the other support plate 171 is slidingly arranged at the bottom of the transfer tray 61. The avoiding member comprises a fourth driving member arranged at the bottom of the transfer tray 61, which is used to drive the support plates 171 to slide and make the two support plates 171 be located on the same straight line. The fourth driving member comprises a micro push rod 18 arranged at the bottom of the transfer tray 61, and the length direction of the output shaft of the micro push rod 18 is parallel to the frame of the transfer tray 61. The end of the support plate 171 is hingedly connected to the output shaft of the micro push rod 18. The avoiding member further comprises a recovery member, which is used to drive the hingedly connected ends of the two support plates 171 to move towards the corners of the transfer tray 61 when the support plates 171 are moved back, so that the two support plates 171 are perpendicular to each other. The recovery member comprises a recovery spring 19 arranged at the corner of the transfer tray 61, and the other end of the recovery spring 19 is fixedly arranged at the hingedly connected end between the two support plates 171.

[0039] When the transfer tray 61 passes through the material plate 20, the two support plates 171 are perpendicular to each other and hidden in the bottom of the transfer tray 61. After the transfer tray 61 passes through the two material plates 20, the micro push rod 18 is started to pull the support plates 171 to move, so that the two support plates 171 are located on the same straight line, and a support is formed at the bottom of the transfer tray 61, which facilitates the transfer of the material plate 20. When the support plates 171 are recovered, the recovery spring 19 pulls the hingedly connected ends of the two support plates 171 to be parallel to the direction of the corners of the transfer tray 61 when the support plates 171 are moved back, and the two support plates 171 are hidden in the bottom of the transfer tray 61. The operation is simple and convenient.

[0040] The implementation principle of the workpiece storage and access integrated automatic stockyard in the embodiment of the application is as follows: When the blank parts are processed, the blank parts are placed on the material plate 20, and the material plate 20 is stacked on the transfer trolley 15. When the transfer trolley 15 enters the stockyard body 1, the first walking wheel 153 enters the stockyard body 1 first. At this time, the guide roller 164 is opposite to the guide rail 163. During the process that the transfer trolley 15 enters the stockyard body 1, the guide roller 164 enters the sliding groove 165 on the guide rail 163 and translates along the guide rail 163, thereby transferring the material plate 20 into the stockyard body 1. Subsequently, the material plate 20 in the feeding area 3 is transferred to the blank area 4, at this time, the transfer tray 61 is driven to be located above the material plate 20 by the first motor 622 and the second motor 631, and the transfer tray 61 is vertically moved to pass through the material plate 20, then the transfer tray 61 is moved by the rotation of the gear 632 driven by the second motor 631, the transfer tray 61 moves horizontally, the first fixed plate 641 is moved to be below the first fixed seat 642, then the transfer tray 61 is moved upward by the first motor 622, so that the fixed rod 643 is inserted into the first positioning hole, thereby fixing the material plate 20 in the transfer tray 61, then the transfer tray 61 is driven by the first motor 622 and the second motor 631 to transfer the material plate 20 to the blank area 4; Subsequently, the blank parts in the blank area 4 are transferred to the material taking tray 71, at this time, the uppermost material plate 20 is first moved into the material taking tray 71 by the first motor 622 and the second motor 631, then the material taking tray 71 is translated by the third motor 721, the material taking tray 71 moves to drive the suspension plate 731 to translate, the suspension plate 731 drives the suspension rod 733 to move horizontally, the suspension rod 733 moves horizontally into the suspension seat 732 to hang the material plate 20 on the transfer tray 61, then the transfer tray 61 moves the material plate 20 to the action range of the material taking mechanical arm; Subsequently, the material taking mechanical arm grasps the blank parts on the material plate 20 to the machining device for machining, the finished products after machining are transferred to the material plate 20 by the material taking mechanical arm, when the blank parts on the material plate 20 are machined, the material plate 20 is transferred to the material plate stacking area 5 by the transfer mechanism 6, when all the blank parts are machined, the material plate stacking area 5 is removed by the feeding box door 2, in this process, the ordered warehousing of the blank parts and the convenient warehousing of the finished products are realized, and the efficient cooperation with the machining unit is improved.

[0041] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
