Abstract

An unloading and feeding device can include a driving mechanism, a mounting member, two elastic assemblies, a rotating assembly, a pressing member, and a picking member. The driving mechanism can include a base plate having an edge, a movable assembly coupled to the base plate, a first limiting member coupled to the base plate adjacent to the edge, and a second limiting member coupled to the base plate away from the edge. The first limiting member and the second limiting member are positioned at opposite sides of the base plate. The mounting member can be coupled to the movable assembly. The elastic assemblies can be positioned at opposite sides of the movable assembly, corresponding to the first and second limiting members respectively. Each of the elastic members can include a movable member extending through the mounting member.

First claim

What is claimed is:

1. An unloading and feeding device comprising:
a driving mechanism comprising:
a base plate having an edge;
a movable assembly coupled to the base plate;
a first limiting member coupled to the base plate adjacent to the edge; and
a second limiting member coupled to the base plate away from the edge, wherein the first limiting member and the second limiting member is positioned at opposite sides of the base plate;

a mounting member coupled to the movable assembly;
two elastic assemblies coupled to the mounting member and positioned at opposite sides of the movable assembly, and corresponding to the first and second limiting members respectively; each of the elastic members comprising:
a movable member extending through the mounting member;

a rotating assembly coupled to the mounting member;
a pressing member coupled to the rotating assembly; and
a picking member coupled to the pressing member, wherein the rotating assembly is configured to rotate the pressing member and the picking member, enabling the pressing member to press one of the movable members of the two elastic assemblies, causing the movable member to protrude out of the mounting member; the movable assembly is configured to move the rotating assembly and the mounting member, enabling the movable member to protrude out of the mounting member to resist against the corresponding first or second limiting member.

2. The unloading and feeding device of claim 1 , wherein the movable assembly comprises two bases positioned on the base plate spaced from each other, a main rod coupled to the bases, and a sliding member slidably sleeved on the main rod; opposite ends of the main rod are coupled to the bases respectively, the mounting member is coupled to the sliding member.

3. The unloading and feeding device of claim 2 , wherein the movable assembly further comprises a piston coupled to the main rod, the sliding member defines a receiving cavity, the main rod extends through the receiving cavity, the piston is received in the receiving cavity.

4. The unloading and feeding device of claim 2 , wherein the movable assembly further comprises at least one guiding rod coupled to the bases and parallel to the main rod, and movably extends through the sliding member.

5. The unloading and feeding device of claim 1 , wherein the rotating assembly comprises a cylinder coupled to the mounting member and a rotating member received in the cylinder, the pressing member is coupled to the rotating member.

6. The unloading and feeding device of claim 5 , wherein the rotating assembly further comprises a toothed piston having a toothed portion thereon; the cylinder defines a first cavity and a second cavity communicating with the first cavity; the toothed piston is received in the first cavity and the toothed portion faces the second cavity; the rotating member is positioned in the second cavity and having a gear thereon, the gear meshes with the toothed portion.

7. The unloading and feeding device of claim 6 , wherein the rotating assembly further comprises a driving member coupled to the rotating member; the pressing member is coupled to the driving member.

8. The unloading and feeding device of claim 1 , wherein the mounting member comprises a first mounting plate coupled to the movable assembly and a second mounting plate coupled to the first mounting plate; the elastic members is mounted to the first mounting plate, the rotating assembly is mounted to the second mounting plate.

9. The unloading and feeding device of claim 8 , wherein each of the elastic assemblies comprises a mounting seat and an elastic member, the mounting seat is mounted to the mounting member, the movable member extends through the mounting seat and an end of the movable member protrudes out of the mounting member; the movable member provides a flange thereon, the elastic member is sleeved on the movable member and received in the mounting seat; opposite ends of the elastic member resist against the first mounting plate and the flange respectively.

10. The unloading and feeding device of claim 9 , wherein the first limiting member comprises a base body coupled to the base plate, and a buffering portion coupled to the base body; the buffering portion is aligned to an end of the corresponding movable member.

11. The unloading and feeding device of claim 10 , wherein a structure of the second limiting member is similar to a structure of the first limiting member; the second limiting member comprises a base body coupled to the base plate, and a buffering portion coupled to the base body.

12. The unloading and feeding device of claim 11 , wherein the unloading and feeding device further comprises a connecting rod coupled to the pressing member; the picking member is coupled to the connecting rod; the pressing member provides a pressing portion thereon configured to resist against an end of the movable member.

13. An unloading and feeding device comprising:
a driving mechanism comprising:
a base plate having an edge;
a movable assembly coupled to the base plate;
a first limiting member coupled to the base plate; and
a second limiting member coupled to the base plate, wherein the first limiting member and the second limiting member is positioned at opposite sides of the base plate, a distance between the first limiting member and the edge is smaller than the same between the second limiting member and the edge;

a mounting member coupled to the movable assembly;
two elastic assemblies coupled to the mounting member and positioned at opposite sides of the movable assembly, and corresponding to the first and second limiting members respectively; each of the elastic members comprising:
a movable member extending through the mounting member;

a rotating assembly coupled to the mounting member;
a pressing member coupled to the rotating assembly; and
a picking member coupled to the pressing member, wherein the rotating assembly is configured to rotate the pressing member and the picking member, enabling the pressing member to press one of the movable members of the two elastic assemblies, causing the movable member to protrude out of the mounting member; the movable assembly is configured to move the rotating assembly and the mounting member, enabling the movable member to protrude out of the mounting member to resist against the corresponding first or second limiting member.

14. The unloading and feeding device of claim 13 , wherein the movable assembly comprises two bases positioned on the base plate spaced from each other, a main rod coupled to the bases, and a sliding member slidably sleeved on the main rod; opposite ends of the main rod are coupled to the bases respectively, the mounting member is coupled to the sliding member.
