[0041] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figure 1-7 As shown together, the utility model provides a feeding device, including a support frame 2, a workpiece placement frame 1 is rotatably provided on the top of one side of the support frame 2, the workpiece placement frame 1 is L-shaped, and the inner side of the workpiece placement frame 1 is used to contact with the workpiece.

[0044] A limiting portion 7 is provided on the opposite side of the long side of the workpiece placement rack 1 , and the limiting portion 7 is a limiting rod used to limit the movement of the workpiece and prevent the workpiece from tipping over; the limiting portion 7 is fixedly connected to the inner side of the end of the short side of the workpiece placement rack 1 .

[0045] The loading device also includes a first pad block 8, which is arranged on the side of the short side end of the workpiece placement rack 1 away from the limiting portion 7. The setting of the first pad block 8 makes the height of the workpiece placement rack 1 at a suitable position for receiving the workpiece; through the first pad blocks 8 of different heights, the long side of the workpiece placement rack 1 and the support frame 2 can be separated by a certain distance when in a vertical position to avoid the angle between the two being too small. When an accident occurs, the separated angle can protect the operator.

[0046] The workpiece rack 1 is connected to the support frame 2 through a hinge 5; the workpiece rack 1 rotates between a vertical position and a horizontal position around the hinge 5; specifically, one end of the hinge 5 is arranged at one end of the support frame 2; the other end of the hinge 5 is arranged at the end of the long side of the workpiece rack 1, or the other end of the hinge 5 is arranged on the long side of the workpiece rack 1 at a specified distance from the end, and the specified distance is not greater than half the length of the long side of the workpiece rack 1.

[0047] A first feed portion 4 is provided on the long side of the workpiece placement frame 1, and a second feed portion 10 extending horizontally is provided on the top of the support frame 2; both the first feed portion 4 and the second feed portion 10 use rollers, transmission belts, etc. to facilitate the movement of the workpiece thereon.

[0048] When the workpiece placement rack 1 rotates around the hinge portion 5 to a horizontal state, the first feeding portion 4 and the second feeding portion 10 are connected in the horizontal direction to transport the workpiece to other workstations.

[0049] Further, the first feed part 4 is arranged in multiple rows perpendicular to the conveying direction, and the second feed part 10 is arranged in multiple rows perpendicular to the conveying direction;

[0050] Further, the first feeding part 4 and the second feeding part 10 are at least partially staggered in a direction perpendicular to the conveying direction;

[0051] Furthermore, when the first feed section 4 and the second feed section 10 are arranged alternately, the discharge end of the first feed section 4 is located behind the feed end of the second feed section 10 in the conveying direction; or, the discharge end of the first feed section 4 extends along the conveying direction to a specified length in front of the feed end of the second feed section 10, so that the transition of the workpiece from the workpiece placement rack 1 to the support rack 2 is smoother.

[0052] A driving member 3 is provided between the workpiece placement frame 1 and the support frame 2. The driving member 3 may be an actuator such as a cylinder or a hydraulic cylinder. One end of the driving member 3 is hinged to the support frame 2, and the other end is hinged to the workpiece placement frame 1. The driving member 3 can drive the workpiece placement frame 1 to rotate around the hinge 5. In this arrangement, the main body of the driving member 3 is inside the support frame 2, does not occupy additional volume, and has a more compact structure.

[0053] Specifically, the hinge point 11 between the driving member 3 and the workpiece placement rack 1 is located on the left side of the hinge portion 5, and the workpiece placement rack 1 is rotated to a horizontal position by a thrust; in this way, the support is relatively more stable.

[0054] Or, if Figure 5 As shown, the hinge point 11 between the driving member 3 and the workpiece placement rack 1 is located on the right side of the hinge portion 5, and the workpiece placement rack 1 is rotated to a horizontal position by pulling force; in this way, the action stroke of the driving part 3 is relatively short.

[0055] The hinged portion 5 is a hinge device; preferably, the hinged portion 5 is a hinge with a torsion spring structure or a damping structure. By adding a torsion spring structure, the falling speed of the workpiece placement rack 1 is slowed down to a certain extent, making the fall more stable, avoiding impact on the drive mechanism 3 or safety hazards caused by rapid falling.

[0056] The feeding device also includes a sensing element 6, which is arranged on the workpiece placement rack 1. The sensing element 6 can be a pressure sensor or a photosensor, which is used to sense the placement of the workpiece; the sensing element 6 and the driving element 3 are both connected to the control system. When the sensing element 6 senses the placement of the workpiece, the driving element 3 can be automatically controlled to work.

[0057] Working principle: When a workpiece (such as an impeller transferred from another station) needs to be loaded, the workpiece is pushed from the transfer vehicle into the workpiece placement rack 1, and the driving member 3 is activated to rotate the workpiece placement rack 1 from a vertical position to a horizontal position (aligned with the support frame 2). At this time, the first feed part 4 and the second feed part 10 are horizontally connected, and the workpiece moves along the first feed part and the second feed part to a specified station, such as a testing station. When the workpiece needs to be removed, it can also be removed through this device.

[0058] Example 2

[0059] like Figure 8As shown, the utility model provides a loading device. The difference between this embodiment and embodiment 1 is that the loading device also includes a second pad 9, which is arranged at an end portion where the short side and the long side of the workpiece placement frame 1 are connected, and is used to separate the workpiece placement frame 1 and the support frame 2 to prevent accidents such as pinching hands.
