With continued reference to fig. 1, the bending device includes a mounting platform 400 for carrying other structures of the bending device for easy installation and maintenance by an operator, and for facilitating the overall modular arrangement of the bending device for improved performance of the bending device.

Illustratively, the carrier 100 is preferably made of an antistatic material, which can prevent the smart watch from affecting part of the performance under the action of an electrostatic field in the bending process, and prevent the smart watch from being electrostatically adsorbed to dust in a processing workshop. Simultaneously, prevent that static material can avoid the power of bending device other structures to act on the intelligent wrist-watch, avoid causing the damage of intelligent wrist-watch circuit, play the guard action to the intelligent wrist-watch. Further, the carrier 100 is preferably made of antistatic polyoxymethylene, and the antistatic polyoxymethylene not only meets the antistatic effect, but also has relatively small hardness, can avoid rigid collision between the carrier 100 and the smart watch during assembly and disassembly, and is beneficial to improving the safety of the smart watch.

In operation, an operator first places the smart watch in the receiving slot 110, then secures the flat cable fixing mechanism 300 to constrain the positions of the flat cable and the smart watch, and then activates the bending mechanism 200 to bend.
As shown in fig. 1 and 2, fig. 2 is a schematic structural view of the carrier 100, the mounting platform 400, and the second guide assembly 500. For ease of handling by the operator, the bending device further comprises a second guide assembly 500.

After the operator completes the assembly of the smart watch, the carrier 100 is pushed to the lower part of the bending mechanism 200 through the second guide assembly 500 to bend, and the operation is convenient.
With continued reference to fig. 1 and fig. 2, specifically, the second guiding assembly 500 includes a second guide rail 510 and a second slider 520, the second guide rail 510 is disposed on the mounting platform 400 along the X direction, the second slider 520 is disposed on the carrier 100, and the second slider 520 is slidably connected with the second guide rail 510, so that the second slider 520 can drive the carrier 100 to switch between the assembling station and the bending station, and the structure of the second guide rail 510 and the second slider 520 is beneficial to ensuring the stability of the movement process of the carrier 100, and avoiding the occurrence of the phenomenon such as jamming.
As shown in fig. 2, in order to improve the working efficiency, the flat cable fixing mechanism 300 and the carrier 100 are positioned by pins and pin holes, and the flat cable fixing mechanism 300 is detachably connected with the carrier 100 by magnets which are respectively arranged on the flat cable fixing mechanism 300 and the carrier 100 and have magnetic poles attracted to each other, so that the flat cable fixing mechanism 300 and the carrier 100 can be quickly and detachably matched, repeated operation of an operator is facilitated, and the working efficiency of the operator is improved.
The detailed structure of the flat cable fixing mechanism 300 will now be described with reference to fig. 3.
As shown in fig. 3, the flat cable fixing mechanism 300 includes a limiting member 310 and a supporting member 320, the limiting member 310 can constrain the flat cable between the supporting member 320 and the limiting member 310, the supporting member 320 includes a first pressing head 323, the first pressing head 323 is opposite to a portion of the flat cable between the smart watch and the flat cable fixing mechanism 300, and the bending mechanism 200 is used for bending the flat cable in cooperation with the first pressing head 323, which is beneficial to improving bending efficiency and bending precision. Meanwhile, the flat cable fixing mechanism 300 can restrict the extending direction of the flat cable, and damage caused by interference between the flat cable and the bending mechanism in the bending process is avoided. Meanwhile, the flat cable can be fixed through the mutual cooperation of the limiting piece 310 and the supporting piece 320, an operator can select any position of the bent flat cable, when the supporting piece 320 is close enough to the internal components of the intelligent watch, the limiting piece 310 and the supporting piece 320 are fixed, the first pressure head 323 and the bending mechanism 200 are mutually matched, the flat cable can be bent to be close to one end of the intelligent watch, damage to other structures of the intelligent watch is avoided, and meanwhile bending efficiency and bending precision can be guaranteed.
Referring to fig. 1 and 3, in order to improve the working efficiency, two sets of carriers 100, a flat cable fixing mechanism 300 and a bending mechanism 200 may be disposed on the same mounting platform 400, and the same operator may perform the operation at the same time.
Referring to fig. 3, as an alternative, the flat cable fixing mechanism 300 further includes a fixing plate 330, and the limiting member 310 is rotationally connected with the fixing plate 330, so that the limiting member 310 is convenient to switch between a flat cable limiting state and an open state, which is favorable for ensuring the working efficiency of an operator, and is favorable for ensuring that the positioning precision of repeatedly operating the limiting member 310 is accurate, and further is favorable for improving the bending precision of the bending device, so that the bending precision of each smart watch is consistent when the smart watches produced in batch are ensured to be bent.
The detailed structure of the stopper 310 will now be described with reference to fig. 3.
Further, as shown in fig. 3, the stopper 310 includes a connection part 311 rotatably connected with the fixing plate 330 to ensure that the stopper 310 can rotate with respect to the fixing plate 330. Meanwhile, the limiting piece 310 further comprises a limiting portion 312, one end of the limiting portion 312 is connected with one end, far away from the fixing plate 330, of the connecting portion 311, the extending direction of the limiting portion 312 and the connecting portion 311 are arranged at an obtuse angle, so that the limiting portion 312 can restrict the flat cable in the opposite direction of extending the flat cable, and interference with the bending mechanism 200 is avoided. Meanwhile, the obtuse angle structure is that the angle change of the flat cable is relatively small, the difficulty of fixing the flat cable is reduced, and the damage to the connection position of the flat cable and the components is avoided.
Still referring to fig. 3, further, in order to facilitate the operation of the operator, the limiting member 310 further includes a holding portion 313 disposed on one side of the connecting portion 311, and the operator can drive the limiting member 310 to turn over through the holding portion 313, which is beneficial to improving the safety of the turning process.
The detailed structure of the fixing plate 330 will now be described with reference to fig. 3. As shown in fig. 3, it can be understood that the fixing plate 330 is provided with a avoiding groove 331, so that structures such as a flat cable can extend out from the middle of the avoiding groove 331 of the fixing plate 330, so as to facilitate subsequent bending work. The supporter 320 includes a mounting portion 321, and the mounting portion 321 is connected to the fixing plate 330 to fix the supporter 320 on the fixing plate 330, thereby improving stability of the supporter 320 during bending. Further, the supporting element 320 further includes a supporting portion 322, the upper surface of the supporting portion 322 is lower than the upper surface of the fixing plate 330, and the lower surface of the supporting portion 322 can be located inside the housing, so that the height of the supporting portion 322 can be as low as possible, and the lower surface of the supporting portion 322 is as close to the components as possible, i.e. the fixing position of the flat cable fixing mechanism 300 can be as close to the components as possible, so as to facilitate bending of the flat cable at the corresponding position. Illustratively, the distance between the lower surface of the support portion 322 and the flat cable located therebelow may be between 0.5mm and 3mm, and an operator may select any one of the ranges between 0.5mm and 1mm, 1mm and 1.5mm, 1.5mm and 2mm, 2mm and 2.5mm and 3mm, or even larger ranges, depending on the specific bending position, which is not limited herein.
With continued reference to fig. 3, it can be understood that, when the bending mechanism 200 bends the flat cable, the flat cable is bent at a large angle, and has a large tensile force on two sides of the bending position, so that the flat cable is deformed and inclined on the lower surface of the supporting portion 322, and the distance can provide a space for the flat cable to deform under the action of the tensile force, so as to avoid the deformation tensile force of the flat cable from acting on the connection position of the flat cable and the components, thereby being beneficial to ensuring the connection stability of the flat cable in the smart watch.
With continued reference to fig. 3, further, when the spacing member 310 constrains the flat cable between the spacing member 310 and the supporting member 320, the spacing portion 312 and the supporting portion 322 are respectively abutted against two sides of the flat cable, the position of the flat cable is fixed by the clamping force between the spacing portion 312 and the supporting portion 322, and the spacing portion 312 is in surface-to-surface contact with the flat cable, and the supporting portion 322 is also in surface-to-surface contact with the flat cable, so that the improvement of the contact area is beneficial to ensuring the stability of clamping the flat cable, and the damage of the flat cable can be avoided.
Referring to fig. 3, in order to avoid movement of the spacing portion 312 when the flat cable is fixed, a magnet is disposed on a side of the connecting portion 311 facing the fixing plate 330, and a magnet with opposite magnetic poles is disposed at a corresponding position of the fixing plate 330, when an operator turns the spacing portion 312 to a position for fixing the flat cable, the two magnets disposed correspondingly can attract each other to fix the position of the spacing member 310, so as to improve stability of the spacing portion 312 for fixing the flat cable.
Meanwhile, the supporting piece 320 further comprises an adsorption part arranged on the supporting part 322, the adsorption part is used for adsorbing the flat cable, further restraining the position of the flat cable, avoiding the flat cable from moving, and being beneficial to ensuring the bending precision. During operation, an operator can manually overturn the wire towards the surface of the supporting part 322, start the adsorption part to adsorb the wire, then make the limiting part 312 and the wire abut against each other at the overturning limiting part 310 to fix the wire, and improve the fixing effect of the wire.
With continued reference to fig. 3, as an alternative, the support 320 further includes a first pressing head 323 connected to the support portion 322, where the first pressing head 323 cooperates with the bending mechanism 200 to bend the flat cable. Thereby, the first pressure head 323 is matched with the bending mechanism 200 to realize bending of the flat cable. It can be understood that when the flat cable is bent, the flat cable at the bending position has a certain tensile force to the flat cable at two sides, so that in order to avoid damage to the flat cable caused by the tensile force, a certain interval is reserved between the limiting portion 312 and the first pressure head 323, and the flat cable can deform in the middle of the interval, so as to realize the function of protecting the flat cable.
The detailed structure of the bending mechanism 200 will now be described with reference to fig. 4 to 6.
As shown in fig. 4, as an alternative, bending mechanism 200 includes a mounting block 210, a bending drive 220, and a bending assembly 230.

Then, the operator manually turns the wire upward, starts the adsorption part to adsorb the wire, and then operates the hand-hold part 313 to turn the limiting part 310 over, so that the wire is restrained between the limiting part 312 and the supporting part 322.
Then, as shown in fig. 1 and 4, the operator pushes the carrier 100 to reach the bending station. The bending driving member 220 is activated and drives the first slider 242 to move in the guiding direction of the first guide rail 241, so that the second ram 231 moves in the direction of the first ram 323 and bends the flat cable. At this time, the heating member 232 can heat the second ram 231 to raise the temperature of the second ram 231, and the bending driving member 220 drives the second ram 231 to maintain a state of fixing the flat cable together with the first ram 323, and maintain the state for 10 seconds.
After the flat cable is bent, as shown in fig. 4, the heating element 232 is turned off, and the second pressing head 231 is retracted by the bending driving element 220, so that the second pressing head 231 moves away from the flat cable and the first pressing head 323, at this time, the cooling assembly is started, and air is blown to the flat cable through the ventilation pipe to reduce the temperature of the flat cable.
In the process of performing pressure maintaining and bending on one of the smart watches, an operator places the smart watch on the other set of carrier 100 and repeats the above operation, thereby fully utilizing the pressure maintaining and bending time.
After the flat cable is bent, the operator operates the bending driving member 220 to drive the second pressing head 231 to move away from the first pressing head 323, and then manually pushes the carrier 100 to move to the assembly station. The operator holds the portion 313, the constraint of unlocking the spacing portion 313 to the winding displacement, then removes the constraint of fixed plate 310 to the intelligent wrist-watch, and the operator takes out the intelligent wrist-watch from holding tank 110, accomplishes the winding displacement bending of an intelligent wrist-watch.
