In order to achieve that the folding screen does not present a slit problem in both the fully unfolded and fully folded together condition, the space allowed for its mounting on the folding screen is also limited, resulting in a hinge of the folding screen which is necessarily small in size. For small size folding screen hinges, the difficulty of assembling them to the product is high. While some existing folding screen hinge assembly devices enable automatic assembly of the hinge, most of them are adapted to hinges of rigid material.

In addition, some manufacturers use automated equipment to assemble the resilient parts. For example, a gripping device such as a robot arm or an automatic gripping mechanism is used to grip the elastic part, and the elastic part is assembled on the upright post of the product part.

the present embodiment discloses a press-fitting apparatus for elastic parts of a folding screen hinge, wherein the elastic parts 80 (shown in fig. 4) may be elastic parts of the folding screen hinge, such as a cam on a damping mechanism, which is generally a small-sized and particularly preferably elastic TPU member. Of course, in other embodiments, the elastic element 80 may be other components of the hinge of the folding screen, and the material may be other materials having both softness and elasticity. The folding screen hinge elastic part press fitting equipment of this embodiment can realize the function: the resilient member 80 is press fit onto the product member 70 (shown in fig. 4), wherein the product member 70 may be a mounting base plate of the damping mechanism.
The technical problems to be solved in this embodiment are:
1. how to reduce the assembly difficulty of the miniature elastic part 80 and improve the assembly quality.
2. In the process of reducing the assembly difficulty of the elastic part 80, how to realize saving of assembly procedures and improvement of assembly efficiency.
In order to solve the above technical problems, the present embodiment adopts the following scheme:
referring to fig. 1, 2, 3, 4 and 5, in the present embodiment, the press-fitting apparatus for hinge elastic parts of a folding screen includes a first grabbing mechanism 22, a first moving mechanism 21, a first jig 30, a second grabbing mechanism 51 and a second moving mechanism 52. The first grabbing mechanism 22 is disposed on the first moving mechanism 21, and the first grabbing mechanism 22 is driven to move by the first moving mechanism 21. The first jig 30 is located on the moving track of the first grabbing mechanism 22, specifically, the first jig 30 is located below the first grabbing mechanism 22, and the first grabbing mechanism 22 is used for sleeving an elastic part (shown in fig. 4) on a column of a product part 70 (shown in fig. 4) carried by the first jig 30 from top to bottom, so that one-time assembly is completed. The first grabbing mechanism 22 of this embodiment only needs to initially sleeve the elastic part 80 on the upright post of the product part 70, so that the elastic part 80 is kept on the upright post, and the elastic part 80 is not required to be assembled in place, which has lower requirements on the structural shape and size of the first grabbing mechanism 22 and the movement and action of the first grabbing mechanism 22, and can reduce the assembly difficulty. In other embodiments where the product piece 70 is assembled in a recess or hole, the first gripping mechanism 22 may also have the resilient piece 80 pressed into the recess or hole of the product piece 70.
Referring to fig. 1 and 2, in the present embodiment, the second grabbing mechanism 51 is disposed on the second moving mechanism 52, and the second grabbing mechanism 51 is located above the first fixture 30, and the second moving mechanism 52 can drive the second grabbing mechanism 51 to move up and down towards or away from the first fixture 30. The second grabbing mechanism 51 includes a clamping device and a pressing arm 5121 disposed on the clamping device, where the pressing arm 5121 extends in an up-down direction; after the second grabbing mechanism 51 moves from top to bottom toward the first fixture 30, the product part 70 is clamped by the clamping device, and the elastic part is pressed from top to bottom by the pressing arm 5121, so as to complete the secondary assembly. In the foregoing process, the second gripping mechanism 51 can press-fit the elastic part 80 on the upright post of the product part 70, so that the elastic part 80 can be assembled in place, and also can clamp the product part 70, so that the assembling process and the clamping process are integrated into one process, thus saving the process and improving the assembling efficiency.

After the elastic part 80 is preassembled, the product part 70 is further press-fitted onto the column of the product part 70 using the process of moving the second gripper mechanism 51 from up to down so that it is assembled in place. Since the second grabbing mechanism 51 only needs to press the product part 70, the requirements on the structure, shape, movement, action and the like of the second grabbing mechanism 51 are low, and the assembly difficulty is high. By means of the above-mentioned method, the assembly process of the elastic part 80 is performed twice, so that the assembly difficulty of the elastic part 80 is greatly reduced.
2. The second gripping mechanism 51 of the present embodiment moves down and grips the product part 70, during which the second gripping mechanism 51 can press-fit the elastic part 80 onto the upright of the product part 70. In this way, the gripping process of the second gripping mechanism 51 and the secondary press-fitting process of the product part 70 can be integrated into one process, so that the number of processes is reduced, the assembly time is saved, the assembly efficiency is improved, and the assembly cost can be reduced.

Referring to fig. 1, 2, 3 and 4, in the present embodiment, the second moving mechanism 52 is used to drive the second grabbing mechanism 51 to move, for example, to reciprocate the second grabbing mechanism 51 along the Y axis and move up and down along the Z axis. The second movement mechanism 52 includes a second transverse drive assembly and a second longitudinal drive assembly. The second longitudinal driving component is arranged at the output end of the second transverse driving component, the second longitudinal driving component is driven to linearly move in the X-Y plane by the aid of the second transverse driving component, and specifically, the first transverse driving component drives the first longitudinal driving component to reciprocate along the X axis.
