Description

[0001] This invention relates to the field of COF bending technology, and in particular to an automated COF bending equipment and an automated bending process. Background Technology

[0002] In VR projects, COF products require bending to a small size and have high rigidity. Neither manual bending using auxiliary jigs with rollers nor bending using robotic arms with suction nozzles can meet product requirements.

Bending with robotic arms with suction nozzles results in COF material detaching during bending due to its hardness, making bending impossible. The difficulty and low production efficiency of bending COF products urgently need to be addressed. Summary of the Invention

The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] A COF automated bending machine, such as Figures 1 to 7 As shown, it includes a moving device 100, a transferring device 200, and a bending device 300;

[0042] The mobile device 100 includes a mobile base 1 and a first drive component 3. The first drive component 3 drives the mobile base 1 to move back and forth. A product platform 2 is provided on the mobile base 1.

[0043] The transfer device 200 includes a transfer base 4, a second drive assembly 5 that drives the transfer base 4 to move back and forth, an adsorption assembly installed on the transfer base 4, and a first rotating assembly 6 that drives the adsorption assembly to rotate; wherein, the transfer base 4 is equipped with a first movable seat 23 and a first left-right reciprocating drive assembly 24 that drives the first movable seat 23 to move left and right reciprocatingly, and the first rotating assembly 6 is installed on the first movable seat 23.

[0044] The bending device 300 is used to bend the product. The bending device 300 includes a bending base 30, a third drive assembly 31 that drives the bending base 30 to move back and forth, a second movable seat 32 mounted on the bending base 30, a second left-right reciprocating drive assembly 33 that drives the second movable seat 32 to move left and right, a bending assembly mounted on the second movable seat 32, a bearing block 34 mounted on the second movable seat 32, and a second rotating assembly 35 that drives the bending assembly to rotate.

[0045] Specifically, in this embodiment, the COF product is placed on the product platform 2. The first driving component 3 drives the moving base 1 forward to the corresponding station of the transfer device 200. Then, the second driving component 5 drives the transfer base 4 to move, so that the adsorption component corresponds to the product platform 2. The adsorption component picks up the COF product on the product platform 2. The moving base 1 retracts and resets. The first rotating component 6 drives the adsorption component to rotate, transferring the COF product to the station of the bending device 300. Then, the bearing block 34 supports the COF product. The adsorption component retracts and resets. The bending component abuts against the part of the COF product that needs to be bent. Then, the second rotating component 35 drives the bending component to rotate to bend the COF product, realizing automated operation. The present invention has a novel structure and a high degree of automation. It can effectively solve the problem that the COF product is too small and has high hardness to be bent, realize automated production, and improve production efficiency.

[0046] In this embodiment, in order to improve processing efficiency and reduce travel distance, preferably, the transfer device 200 and the bending device 300 are arranged facing each other, and the moving device 100 is located between the transfer device 200 and the bending device 300. The first movable seat 23 and the second movable seat 32 are arranged facing each other. Under the action of the first left-right reciprocating drive component 24 and the second left-right reciprocating drive component 33, the first movable seat 23 and the second movable seat 32 can be driven to move respectively, and the first movable seat 23 and the second movable seat 32 can be controlled to move closer to each other or move further away from each other, so as to facilitate the adjustment of the distance between the transfer device 200 and the bending device 300 without affecting the normal operation of the moving device 100, thus achieving the avoidance effect.

[0047] In this embodiment, the product carrier 2 is provided with an adsorption positioning stage 7, and the adsorption positioning stage 7 is provided with a plurality of first vacuum adsorption holes 8. Specifically, with the above configuration, COF products can be stably adsorbed, preventing product loosening and ensuring stability during horizontal transport.

Specifically, with this configuration, COF products can be easily loaded from all directions during front-end loading, and then the rotary drive 9 drives the product platform 2 to rotate and reset. During rear-end unloading, COF products can also be easily unloaded or removed from all directions, improving production flexibility and avoiding the increased difficulty of loading and unloading due to subsequent product modifications.

[0049] In this embodiment, the first driving assembly 3 includes a first base 10, a first transmission screw 11 rotatably disposed on the first base 10, a first driving motor 12 mounted on one end of the first base 10, and a first transmission slider 13 threadedly sleeved on the outer periphery of the first transmission screw 11. The first transmission slider 13 slidably abuts against the first base 10 and is connected to the movable base 1. The output end of the first driving motor 12 is drivenly connected to one end of the first transmission screw 11. Specifically, in this configuration, the first driving motor 12 drives the first transmission screw 11 to rotate, thereby driving the movable base 1 to reciprocate back and forth.

[0050] In this embodiment, the adsorption assembly includes a swing arm 14, a connecting arm 15, a lifting drive 16, and a transfer adsorption block 17 connected to the output end of the lifting drive 16. One end of the swing arm 14 is connected to one end of the connecting arm 15, and the lifting drive 16 is mounted on the other end of the connecting arm 15. The lower end of the transfer adsorption block 17 is provided with a row of equal-spaced second vacuum adsorption holes 18. The first rotating assembly 6 includes a first rotating motor, the output end of which is connected to the other end of the swing arm 14. The lifting drive 16 is a cylinder. Specifically, under the above configuration, the first rotary motor can drive the swing arm 14 to rotate, and the rotation of the swing arm 14 drives the connecting arm 15 to rotate, which in turn drives the lifting drive component 16 to flip. The lifting drive component 16 can drive the transfer adsorption block 17 to move up and down, which facilitates the adsorption of COF products on the product platform 2. Then, under the action of the first rotary motor, the adsorbed COF products are transferred to the work station of the bending device 300. The working efficiency is high, the operation is simple and fast, and the processing and production time is effectively saved.

[0051] Preferably, the swing arm 14 is perpendicular to the axis of the output shaft of the first rotary motor, and the connecting arm 15 is perpendicular to the swing arm 14.

The second rotating assembly 35 includes a second rotary motor, the output end of which is drivenly connected to the coupling 36. Furthermore, the bearing block 34 is provided with multiple third vacuum suction holes to hold the COF product in place, preventing the COF product from shifting or loosening during bending, thus improving bending stability and reliability. Specifically, when the bending assembly is working, the second rotary motor starts, driving the coupling 36 to rotate, which in turn drives the bending rod 37 to rotate, thereby bending the COF product.

[0054] In this embodiment, the contact point between the bending rod 37 and the COF product, i.e., the position where the bending rod 37 acts on the COF product to bend it, is rounded to avoid scratching the COF product. Furthermore, the front end of the bearing block 34 is located at the position where the COF product needs to be bent, and the front end of the bearing block 34 is also rounded. That is, the bending rod 37 and the bearing block 34 are both rounded at the bending point of the COF product to avoid scratching the COF product, improve the bending quality and efficiency of the product, and reduce defective products.
