Abstract

An inserting device includes a feeding mechanism, a positioning mechanism, and an assembling mechanism. The feeding mechanism includes a first supporting plate, a second supporting plate, a lifting assembly and a single-axis sliding table. The second supporting plate includes a first place position and an adjacent second place position. The second supporting plate and the first supporting plate can form a receiving space. The lifting assembly lifts trays located on the first place position and the second place position. The single-axis sliding table is received in the receiving space. The single-axis sliding table includes a sliding block. The sliding block receives the tray dropped from the first placing position and further carries the tray away from the first placing position. The positioning mechanism includes a clamping jaw. The clamping jaw clamps a workpiece from the tray and positions the workpiece again. The assembling mechanism assemblies the workpiece on a product.

First claim

What is claimed is:

a second feeding mechanism, the second feeding mechanism comprising:
a supporting structure, comprising:
a first supporting plate;
a second supporting plate positioned on the first supporting plate, the second supporting plate defining a first place position and an adjacent second place position, the second supporting plate and the first supporting plate cooperatively forming a receiving space;

a lifting assembly comprising lifting cylinders each with a pushing rod, the lifting cylinders are located below the first supporting plate, the pushing rod of each lifting cylinder passing through the first supporting plate and below the second supporting plate, wherein the pushing rod of each lifting cylinder is configured to hold trays placed on the first place position and the second place position; and
a single-axis sliding table received in the receiving space, the single-axis sliding table comprising a sliding block configured to receive at least one tray dropped from the first place position and further configured to move the tray away from the first place position and towards the second place position;

a positioning mechanism comprising a clamping jaw assembly and a positioning assembly, the clamping jaw assembly having a first clamp groove, the positioning assembly having a second clamp groove, the clamping jaw assembly configured to clamp a workpiece from the tray held on the sliding block via the first clamp groove, and further place the workpiece into the second clamp groove to position the workpiece secondly; and
an assembling mechanism comprising a manipulator, the manipulator configured to clamp the workpiece from the second clamp groove and insert the workpiece into the product.

2. The inserting device of claim 1 , wherein the first feeding mechanism comprises a first conveyor line, a second conveyor line coupled to the first conveyor line, and a third conveyor line coupled to the second conveyor line, the first feeding mechanism comprises a blocking assembly, the blocking assembly is positioned on the second conveyor line.

3. The inserting device of claim 2 , wherein the blocking assembly comprises a first blocking member, a second blocking member and a third blocking member; the first blocking member faces the second blocking member; the first blocking member and the second blocking member are located on sides of the second conveyor line, and are arranged along a direction parallel to a conveying direction of the second conveyor line; the third blocking member is located on a side of the first blocking member and the second blocking member farthest away from the first conveyor line, the inserting position is determined by the positioning of the second blocking member and the third blocking member both of which place the product for insertion.

4. The inserting device of claim 3 , wherein the first feeding mechanism further comprises a sensing assembly configured to detect a presence of the product located on a side of the first blocking member and the second blocking member close to the first conveyor line, and configured to drive the first blocking member, the second blocking member, and the third blocking member to cooperatively place the product in the inserting position.

5. The inserting device of claim 1 , wherein the second supporting plate defines two receive holes corresponding to the first place position and the second place position respectively, each of the two lifting cylinders is located below the first place position and the second place position and is configured to pass through one of the two receive holes to hold the trays placed on the first place position or the second place position.

6. The inserting device of claim 5 , wherein the lifting cylinder which is located below the second place position is configured to lift the tray to pass through the receive hole corresponding to the second place position, and further configured to place the tray on the second place position.

7.
