Description

Technical Field

[0001] The utility model relates to the technical field of circuit board installation, in particular to an end effector for installing an FPC flexible circuit board suitable for a robot. Background Art

[0002] In the field of electronic device manufacturing, due to characteristics such as bendability and thinness, FPC flexible circuit boards are widely used in internal circuit connections of precision electronic products such as mobile phones and smart wearable devices;

[0003] However, in the actual operation and installation process, there are still certain deficiencies in the installation of FPC flexible circuit boards. FPC circuit boards in the prior art are often designed as special-shaped structures, and it may be difficult to control the bending angle and installation position with traditional mechanical clamping or manual installation methods. During installation, the buckling error between the circuit board and the device interface may be relatively large. Moreover, the existing FPC circuit board materials are relatively thin, and the clamping mechanisms in the prior art are generally rigid jigs, which are prone to cause tearing of the circuit board or falling off of solder joints due to stress concentration during the bending process, resulting in a relatively high installation risk. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background art, and to propose an end effector for installing an FPC flexible circuit board suitable for a robot.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An end effector for installing an FPC flexible circuit board suitable for a robot, comprising:

[0007] A universal robotic arm and an installation frame, the installation frame is connected to the driving end of the universal robotic arm through a connection disk;

[0008] Vacuum supports are symmetrically connected in the installation frame, and one group of vacuum supports is fixedly connected to the installation frame, and the other group of vacuum supports is slidably connected to the installation frame;

[0009] A first suction cup is connected to the bottom of the vacuum support, and the first suction cup is used for adsorbing the flexible circuit board.

[0010] Preferably, a first telescopic cylinder is slidably connected to the installation frame, and the driving end of the first telescopic cylinder is fixedly connected to the vacuum support.

[0011] Furthermore, a second telescopic cylinder is fixedly connected to the installation frame, and the driving end of the second telescopic cylinder is fixedly connected to the first telescopic cylinder.

[0012] Preferably, an installation seat is fixedly connected to the installation frame, and a second suction cup is fixedly connected to the installation seat.

[0013] Further, the second suction cup is an oval suction cup.

[0014] Compared with the prior art, the present utility model provides an end effector for installing an FPC flexible circuit board applicable to a robot, having the following beneficial effects:

[0015] 1. In the present utility model, a fixed vacuum support and a sliding vacuum support are symmetrically arranged in the installation frame. The sliding support is driven to move by a first telescopic cylinder, so that the FPC circuit board is naturally bent under the action of vacuum adsorption forces on both sides, and the bending angle can be accurately controlled by the stroke of the cylinder, solving the problem of poor forming accuracy of special-shaped structures in the prior art.

[0016] 2. The present utility model forms a low-pressure area above the circuit board by blowing air with the oval second suction cup, so that the circuit board is bent upward. When used in coordination with the bending action driven by the lateral cylinder, the forming of complex curved surfaces can be realized, avoiding the problem of damage to the circuit board caused by traditional rigid extrusion.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1 - 3 , an end effector for installing an FPC flexible circuit board applicable to a robot includes a universal robotic arm 1 and an installation frame 2. The installation frame 2 is connected to the driving end of the universal robotic arm 1 through a connection disk 203;

[0023] A vacuum support 3 is symmetrically connected to the mounting frame 2, and one set of the vacuum supports 3 is fixedly connected to the mounting frame 2, while the other set of the vacuum supports 3 is slidably connected to the mounting frame 2;

[0024] A first suction cup 301 is connected to the bottom of the vacuum support 3, and the first suction cup 301 is used for adsorbing the flexible printed circuit board.

[0025] A first telescopic cylinder 202 is slidably connected to the mounting frame 2, and the driving end of the first telescopic cylinder 202 is fixedly connected to the vacuum support 3.

[0026] A second telescopic cylinder 201 is fixedly connected to the mounting frame 2, and the driving end of the second telescopic cylinder 201 is fixedly connected to the first telescopic cylinder 202.

[0027] A mounting seat 4 is fixedly connected to the mounting frame 2, and a second suction cup 401 is fixedly connected to the mounting seat 4.

[0028] The second suction cup 401 is an oval suction cup.

[0029] It should be noted that both the first telescopic cylinder 202 and the second telescopic cylinder 201 are precision cylinders that can be purchased on the market.

[0030] Refer to Figures 1 - 3 , during actual operation, the universal robotic arm 1 drives the mounting frame 2 to move above the FPC flexible printed circuit board. At this time, the fixed vacuum support 3 and the sliding vacuum support 3 in the mounting frame 2 are in the initial spacing state, and the first suction cup 301 is vertically downward and aligned with the surface of the circuit board;

[0031] During adsorption, the first suction cups 301 at the bottoms of the two sets of vacuum supports 3 simultaneously activate the vacuum system to adsorb the FPC flexible printed circuit board. After the adsorption is completed, the universal robotic arm 1 lifts the mounting frame 2 upward to separate the circuit board from the storage station;

[0032] Refer to Figures 2 - 3 , when preprocessing the adsorbed circuit board before installation, the first telescopic cylinder 202 on the mounting frame 2 is activated, and its driving end pushes the sliding-side vacuum support 3 towards the fixed side. At this time, the FPC circuit board is squeezed and naturally bent. Then, when blowing air through the air holes on the second suction cup 401, when the air flow sprays out through the second suction cup 401, a low-pressure area is formed above the circuit board by using the Bernoulli principle, causing the circuit board to bend upward and cooperating with the lateral bending action driven by the second telescopic cylinder 201 to achieve the formation of the pre-installation shape.

[0033] Refer to Figures 1 - 3, after completing the bending pre-treatment, when installing the circuit board, the universal robotic arm 1 drives the installation frame 2 to move above the mobile phone installation position again. At this time, the area to be installed of the circuit board needs to be aligned with structures such as interfaces and card slots on the device. The second telescopic cylinder 201 on the installation frame 2 is activated, and its driving end pushes the vacuum support 3 to move downward in the Z-axis direction, so that the connection end of the FPC circuit board is inserted into the device card slot or pressed against the interface. At the same time, the fixed-side vacuum support 3 remains stable to ensure that the position of the circuit board remains unchanged during the buckling process. After the buckling is completed, the vacuum system is turned off, the first suction cup 301 no longer adsorbs the circuit board, and the universal robotic arm 1 drives the installation frame 2 to disengage from the installation position to complete the installation.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
