[0054] A driving device 6 is provided below the first mounting plate 2, and the driving device includes a servo motor 61 and a screw rod 62 connected to the driving end of the servo motor 61.

Among them, the four second guide holes are distributed at the four corners of the driving plate 71. Through the above technical solution, the screw rod 62 rotates under the drive of the servo motor 61, so that the screw nut drives the driving plate 71 to move up and down along the screw rod.

[0055] In some feasible embodiments, the driving device 6 may be an electric cylinder or other device that can drive the driving plate 71 to move in a straight line.

[0056] Five driving rods 72 are arranged on the driving plate 71, and the driving rods 72 are arranged perpendicular to the driving plate 71, and the five driving rods 72 are respectively located below the rollers 514 of the five rods 51.

[0057] When the servo motor 61 drives the driving plate 71 to move upward, the driving rod 72 moves toward the roller 514 of the rod 51 until the roller 514 fits the inclined surface 7221. As the driving rod 72 continues to move upward, the roller 514 rolls along the inclined surface 7221 to push the rod 51 to move along the groove 413 toward the accommodating area, so that the pressing head 511 presses the ear 111 of the upper shell 11 to bend toward the side of the lower shell 12 away from the upper shell 11. It can be understood that after the roller 514 rolls to the end of the inclined surface 7221, the telescopic member 5 no longer moves.

[0058] It should be noted that at least one first guide hole is provided on the carrier plate 4, and a first guide column matching the first guide hole is provided on the drive plate 71, and the first guide hole is on the moving path of the first guide column. A third through hole is provided on the carrier plate 4 at a position relative to the drive rod 72 for the drive rod 72 to pass through.

[0059] In some feasible embodiments, a support member is provided on a side of the base 721 of the driving rod 72 away from the column 722, such as Figure 7 As shown, the support member includes an adjustment block 81 fixed to the driving plate 71 by screws, the adjustment block 81 is provided with a threaded hole, an adjustment screw 82 is inserted into the threaded hole, and the adjustment screw 82 can be rotated to abut against the base 721 of the driving rod 72.

[0060] The carrier plate 4 is provided with a fifth through hole at a position relative to the fourth through hole 415 on the support seat 411, and a second bending member 91 is provided in the fifth through hole. In the present application, the second bending member 91 is a vertically arranged bending rod. Figure 8 , 9 As shown, a limiting block 911 is provided on the side wall of the second bending member 91, and a limiting baffle 92 is provided on the lower side of the carrier plate 4 relative to the fifth through hole. The limiting baffle 92 is provided on the moving path of the limiting block 911 to prevent the second bending member 91 from falling off from the fifth through hole. A second spring 93 is also provided on the limiting block 911, one end of the second spring 93 is connected and fixed to the limiting block 911, and the other end of the second spring 93 is connected and fixed to the wall in the fifth through hole. The second spring 93 is used to make the limiting block 911 move toward the limiting baffle 92.

[0061] A bending support block 73 is provided on the driving plate 71 at a position relative to the second bending member 91 . As the driving plate 71 moves toward the carrier plate 4 , the bending support block 73 abuts against the second bending member 91 , so that the second bending member 91 squeezes the ear 111 to fit the lower shell 12 .

[0062] Two spaced support plates 22 are further provided on the first mounting plate 2, and the two support plates 22 are respectively disposed on the opposite sides of the two tracks 3.

A cylinder 101 is provided on the second mounting plate 10, and an elastic member 102 that imitates the housing 1 is connected to the telescopic rod of the cylinder 101.

[0063] Wherein, the pressing position is that the carrier plate 4 is located between the elastic member 102 and the driving plate 71, and the loading position is that the carrier plate 4 is located outside the elastic member 102. Driving the carrier plate 4 to move along the track 3 to the loading position by the sliding cylinder can facilitate the user to place the upper housing 11 and the lower housing 12 in the accommodating area.

[0064] Through the above solution, the sliding cylinder drives the carrier plate 4 to move along the track 3 to the loading position for loading;

[0065] After the housing 1 is positioned by the positioning shaft, the sliding cylinder drives the carrier plate 4 to move along the track 3 to the pressing position;

[0066] The cylinder 101 acts to drive the elastic member 102 to move towards the housing 1, thereby fixing the housing 1 in the accommodating area;

[0067] The servo motor 61 acts to drive the driving plate 71 to drive the driving rod 72 to move towards the roller 514 of the rod member 51. Until the roller 514 fits against the inclined surface 7221, as the driving rod 72 continues to move upward, the roller 514 rolls along the inclined surface 7221 to push the rod member 51 to move along the groove 413 towards the accommodating area, so that the pressing head 511 presses the lug 111 of the upper housing 11 to bend towards the side of the lower housing 12 away from the upper housing 11 until the roller 514 rolls to the end of the inclined surface 7221, and the rod member 51 is bent to the first preset position;

[0068] The servo motor 61 continues to act, and the driving plate 71 continuously moves towards the carrier plate 4, and the bending support block 73 abuts against the second bending member 91, so that the second bending member 91 presses the lug 111 to fit against the lower housing 12.

[0069] In some feasible embodiments, the servo motor 61 adopts an integrated servo motor of model PMM6020B, which integrates the ability to measure force and displacement, facilitating the user to observe the displacement distance of the driving plate 71 in real time and the load torque of the servo motor 61 during the bending process.

[0070] In the present invention, specific embodiments are used to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are only for helping to understand the method and its core idea of the present invention; meanwhile, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
