Further, the first bending assembly 22 and the second bending assembly 23 are connected to the same first guide rail 26, so that the first bending assembly 22 and the second bending assembly 23 can be precisely moved closer to or away from the carrier 1.

In some embodiments, in order to ensure the movement stability of the first bending assembly 22 and the second bending assembly 23, the number of the first guide rails 26 may be two, and the number of the first sliders 27 may be four. The two first guide rails 26 extend in the vertical direction and are arranged side by side in the lateral direction. Two first sliding blocks 27 of the four first sliding blocks 27 are connected to the first bending assembly 22 and are respectively connected with the two first guide rails 26 in a matching manner; the other two first sliders 27 of the four first sliders 27 are connected to the second bending unit 23 and are respectively coupled to the two first guide rails 26.

When the second bending element 232 moves close to the carrier 1, the second contacting portion 2322 first contacts the fourth position-limiting portion 2351, the second contacting portion 2322 elastically deforms the fourth position-limiting portion 2351, and then the second contacting portion 2322 contacts the third position-limiting portion 2341. It can be understood that the fourth limiting portion 2351 can elastically abut against the second abutting portion 2322 to buffer the second bending member 232, so as to reduce the impact between the second bending member 232 and the second limiting member 234 and prolong the service life of the second driving member 233.

In some embodiments, in order to allow the second bending member 232 to stably move with precision, the second bending assembly 23 further includes a fourth guiding member 237.

In order to reduce the risk of the second bending member 232 colliding with the second driving member 233 when the second bending member 232 moves towards the direction close to the second driving member 233, in some embodiments, when the second bending member 232 moves to the position closest to the second driving member 233, a second safety gap 238 is formed between the second driving member 233 and the second bending member 232, so that the second bending member 232 can float in the second safety gap 238, the risk of colliding with the second driving member 233 is reduced, and the service life of the second driving member 233 is prolonged.

The pressing head is disposed on the head of the pressing member 227 and faces the carrier 1, and the pressing head 2271 can abut against the flat cable 200 fixed on the carrier 1 to further press and fix the flat cable 200. In the moving direction of the pressing member 227, the third abutting portion 2272 is disposed between two ends of the pressing member 227 and can be used for abutting another set of the first elastic member 225 and the first limiting member 224 to limit the movement of the pressing member 227.

When the pressing member 227 moves toward the direction close to the carrier 1, the pressing head 2271 can abut against the flat cable 200 to press and position the flat cable 200, so as to prevent the flat cable 200 from shifting during the bending process and improve the bending precision.

the first folding head 2221 and the second folding head 2321 cooperate to bend the flat cable 200 into a predetermined shape.

The bending apparatus 100 guides the first base 221 and the second base 231 to move close to the carrier 1 accurately by the cooperation of the first guide 3 and the second guide 4, so that the first bending member 222 and the second bending member 232 can move accurately to be aligned with the flat cable 200 to be bent on the carrier 1; the first stopper 2241 abuts against the first abutting portion 2222 to restrict the movement of the first bending member 222, thereby preventing the first bending member 222 from moving excessively to break the flat cable 200; the second stopper 2251 abuts against the first abutting portion 2222 to elastically restrict the movement of the first bending member 222, so as to reduce the impact between the first bending member 222 and the first stopper 224 and prolong the service life of the first driving member 223; by providing the first safety gap 229 between the first driving member 223 and the first bending member 222, the first bending member 222 has enough moving space to avoid the first bending member 222 from colliding with the first driving member 223 in an impact manner; simple structure is reliable, improves work efficiency.

In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
