DETAILED DESCRIPTION
[0026] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

The various technical features in the invention can be combined interchangeably without conflicting with each other.
[0027] Reference Figures 1 to 6 , a feeding structure, comprising a base 1, a slider 2, a first elastic member 5, a second elastic member, a first clamping block 4 and a driving device; the slider 2 is arranged on the base 1, and the slider 2 and the base 1 can slide relatively; one end of the second elastic member is connected to the slider 2, and the other end of the elastic member is connected to the base 1, and the telescopic lateral direction of the second elastic member is arranged along the left-right direction; the first clamping block 4 is arranged on the slider 2, and the first clamping block 4 and the slider 2 can move up and down relatively, and the first clamping block 4 is used to be inserted into a hole 9 reserved on the workpiece; the first elastic member 5 is arranged on the slider 2, and the first clamping block 4 is connected to the slider 2 through the first elastic member 5; the driving device is used to drive the slider 2 to move along the left-right direction to compress or release the first elastic member 5.
[0028] From the above, it can be seen that the base 1 can be used as the lower die of the stamping die, and the workpiece to be stamped is set above the slider 2. A plurality of holes for the first clamping block 4 to be inserted are reserved on the workpiece to be stamped, and these holes are arranged in the left and right directions. In the initial state, the driving device moves the slider 2 in the direction of the second elastic member, so that the second elastic member is in a compressed state. At this time, the first clamping block 4 is also inserted into the hole 9 reserved on the workpiece. When the workpiece needs to be transferred, the driving device releases the slider 2, and under the action of the elastic force generated by the second elastic member, the slider 2 drives the workpiece to move until the elastic potential energy of the second elastic member is released.
[0029] When the workpiece needs to perform a secondary movement, the driving device drives the slider 2 to move in the direction of the second elastic member. After the first clamping block 4 abuts against the workpiece, the first elastic member 5 connected to the first clamping block 4 is forced to be compressed, so that the first clamping block 4 avoids the workpiece.
[0030] When the second elastic member is compressed, the first clamping block 4 is inserted into another reserved hole 9 on the workpiece. Then, the driving device releases the slider 2, and the workpiece is driven to move under the elastic force of the second elastic member. The utility model can realize the transfer of plate-like workpieces.
[0031] In the utility model, the workpiece is a plate.
[0032] Before or after the workpiece is transferred, the workpiece needs to be temporarily positioned. In some embodiments, the feeding structure further includes two elastic components 6 and two second clamping blocks 7, the two elastic components 6 are respectively arranged on the left and right sides of the slider 2, and the two second clamping blocks 7 are respectively arranged on the two elastic components 6 in a one-to-one correspondence, and the clamping blocks are used to be inserted into the holes 9 reserved on the workpiece to limit the workpiece.
[0033] When the driving device drives the slider 2 to move in the direction of the second elastic member, the first clamping block 4 abuts against the workpiece. At this time, the second clamping block 7 is inserted into the space reserved on the workpiece, thereby limiting the workpiece and preventing it from moving in the direction of the second elastic member, thereby forcing the first elastic member 5 connected to the first clamping block 4 to be compressed, so that the first clamping block 4 avoids the workpiece.
[0034] When the driving device releases the slider 2, under the elastic force of the second elastic member, the slider 2 drives the workpiece to move away from the second elastic member through the first clamping block 4. During the movement of the workpiece, the second clamping block 7 abuts against the edge of the hole 9 reserved on the workpiece, and forces the elastic component 6 connected to the second clamping block 7 to compress, so that the second clamping block 7 avoids the workpiece.

Through the setting of the first chamfer 41 and the second chamfer 71, when the first chamfer 41 or the second chamfer 71 is connected to the edge of the hole 9 reserved on the workpiece, a downward component force will be generated at the first chamfer 41 and the second chamfer 71, so that the corresponding first clamping block 4 and the second clamping block 7 move downward. When the surface of the first clamping block 4 facing away from the first chamfer 41 abuts against the workpiece, a force driving the workpiece to move in translation is generated, and the first clamping block 4 does not move downward. When the second clamping block 7 limits the workpiece to prevent the workpiece from moving from right to left, the surface of the second clamping block 7 facing away from the second chamfer 71 abuts against the hole 9 reserved on the workpiece.
