[0032] In some feasible embodiments, the driving device 6 can be an electric cylinder or other devices that can drive the driving plate 71 to move linearly.

[0033] Five driving rods 72 are provided on the driving plate 71. 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.

[0034] 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 slope 7221, as the driving rod 72 continues to move upward, the roller 514 rolls along the slope 7221 to push the rod 51 to move along the groove 413 toward the accommodating area, so that the press head 511 presses the lug 111 of the upper housing 11 to bend toward the side of the lower housing 12 away from the upper housing 11. It can be understood that after the roller 514 rolls to the end of the slope 7221, the telescopic member 5 stops moving.

[0035] It should be noted that at least one first guide hole is provided on the carrier plate 4, and a first guide post for mating with the first guide hole is provided on the driving plate 71. The first guide hole is on the moving path of the first guide post.

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.

[0038] 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 .

[0039] The first mounting plate 2 is also provided with two spaced support plates 22, which are respectively provided on opposite sides of the two rails 3. A second mounting plate 10 is provided between the two support plates 22, the second mounting plate 10 is located on the upper side of the press-fitting position, and a cylinder 101 is provided on the second mounting plate 10, and the telescopic rod of the cylinder 101 is connected to an elastic member 102 that is contoured to the housing 1.

The sliding cylinder drives the carrier plate 4 to move along the track 3 to the loading position, which can facilitate the user to place the upper shell 11 and the lower shell 12 in the accommodating area.

[0041] Through the above solution, the sliding cylinder drives the carrier plate 4 to move along the track 3 to the loading position for loading; 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 press-fitting position; The cylinder 101 operates to drive the elastic member 102 to move towards the housing 1, thereby fixing the housing 1 in the receiving area; The servo motor 61 operates to drive the drive plate 71 with the drive rod 72 to move towards the roller 514 of the rod member 51. Until the roller 514 abuts against the inclined surface 7221, as the drive 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 receiving area, so that the press head 511 squeezes 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; The servo motor 61 continues to operate, and the drive plate 71 continuously moves towards 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 lug 111 to fit against the lower housing 12.

[0042] In some feasible embodiments, the servo motor 61 uses an integrated servo motor of model PMM6020B. This servo motor is integrated with the ability to measure force and displacement, which is convenient for users to observe the displacement distance of the drive plate 71 in real time and the load torque of the servo motor 61 during the bending process.
