[0060] As shown in Figure 4 and Figure 5As shown, the taking-out assembly 200 comprises a fixed column 210, a base plate 220, a positioning column 230 and a negative pressure suction head 240, the axial arrangement of the fixed column 210 is the Z-axis direction, the upper end of the fixed column 210 is fixedly connected to the lower surface of the floating plate 140, the lower end of the fixed column 210 is fixedly connected with the base plate 220, the fixed column 210 is coaxially arranged with the servo driver 150, the positioning column 230 is fixed to the base plate 220 and extends downward relative to the base plate 220, the plurality of positioning columns 230 of the embodiment are arranged at intervals in the circumferential direction and correspond one-to-one with the grooves 12 on the rear cover 1, the positioning column 230 passes through the groove 12 downward to realize the position limitation of the rear cover 1, preferably the outer circumferential surface of the positioning column 230 is attached to the inner arc surface of the groove 12, the negative pressure suction head 240 is connected with an external vacuum generator (not marked), in the embodiment, the vacuum generator is preferably arranged on one side of the base plate 220, all the negative pressure suction heads 240 are communicated with the vacuum generator, so that negative pressure can be generated in the negative pressure suction head 240 to adsorb the rear cover 1, preferably the plurality of negative pressure suction heads 240 are arranged at intervals in the circumferential direction and are installed one-to-one on one side of the claw assembly 300 or on the lower surface of the base plate 220.

[0061] As Figure 6As shown, the claw assembly 300 comprises a mounting block 310, a Y-shaped bracket 320, an extension piece 330 and a sensing piece 340. The upper end of the mounting block 310 is connected with the base plate 220. The mounting blocks 310 of a plurality of claw assemblies 300 are arranged at intervals around the Z-axis direction. The Y-shaped bracket 320 has three end portions, i.e., a first end portion 321, a second end portion 322 and a third end portion 323. Preferably, the three end portions are located in the same vertical plane. The middle position of the Y-shaped bracket 320 is hingedly connected with the middle portion of the mounting block 310. The extension piece 330 is arranged on the mounting block 310. The extension end of the extension piece 330 is hingedly connected with the first end portion 321.

The second end portion 322 extends downward and is located at the same height as the buckle 11 on the rear cover 1. When the second end portion 322 moves towards the buckle 11, it can push the buckle 11 to deform inward so that the buckle 11 can be smoothly clamped into the base portion 21 of the casing 2. The third end portion 323 is used to cooperate with the sensing piece 340 so that the sensing piece 340 can obtain the distance by which the Y-shaped bracket 320 is rotated under the driving of the extension piece 330, i.e., the movement distance of the second end portion 322. In the present embodiment, the middle portion of the mounting block 310 is provided with a clearance groove (not marked) to avoid interference between the mounting block 310 and the third end portion 323. The sensing piece 340 can be directly or indirectly arranged on the mounting block 310. The sensing piece 340 indirectly obtains the movement distance of the second end portion 322 by detecting the position change of the third end portion 323. By obtaining the movement distance of the second end portion 322, it can be determined whether the buckle 11 is pushed to the right position. In the present embodiment, the sensing piece 340 is preferably configured as an optical sensor. In addition, the sensing piece 340 can also be a displacement sensor or other sensors capable of sensing position changes, such as a Hall sensor, etc. When the third end portion 323 passes through the optical sensor, the optical sensor will generate a signal. At this time, it can be determined that the buckle 11 is pushed to the right position. Otherwise, it is considered that the buckle 11 is not pushed to the right position.

[0062] As Figure 6 shown, preferably, the mounting block 310 comprises a first mounting block 311 and a second mounting block 312. The upper end of the first mounting block 311 is detachably connected with the base plate 220. The lower end of the first mounting block 311 is provided with a hinge groove. The middle position of the Y-shaped bracket 320 is arranged in the hinge groove and is hingedly connected by a pin shaft. The second mounting block 312 is detachably connected with the lower end of the first mounting block 311.

[0063] AsFigure 7 As shown, preferably, the claw assembly 300 further comprises an adjusting block 350, which is arranged on the first mounting block 311 and the position of the adjusting block 350 on the first mounting block 311 can be adjusted as required, and the adjusting block 350 is arranged in a manner that at least two waist holes 350a are arranged on the adjusting block 350, the first mounting block 311 is provided with screw holes corresponding to the waist holes 350a, and screws (not shown) are sequentially threaded through the waist holes 350a and the screw holes, and when the screws are screwed, the adjusting block 350 can be pressed tightly on the first mounting block 311, at this time the position of the adjusting block 350 is fixed, when the screws are unscrewed, the adjusting block 350 is loosened, and the adjusting block 350 can slide relative to the screws through the waist holes 350a to realize position adjustment. The sensing piece 340 of the claw assembly 300 is mounted on the adjusting block 350, and the sensing piece 340 can adjust the horizontal position together with the adjusting block 350, so that the sensing piece 340 can adjust the initial horizontal distance from the third end 323 of the Y-shaped support 320 according to actual requirements, and this design facilitates the sensing piece 340 to set different trigger positions to meet the assembly needs of different models of products.

[0064] The working principle of the pressing device of the embodiment is as follows:

[0065] Rear cover material taking: the first X-axis module 120 drives the material taking assembly 200 to move along the X-axis direction to the upper side of the rear cover incoming line body, the rear cover material taking position of the rear cover incoming line body temporarily stores a rear cover 1 to be installed, the servo driving part 150 drives the material taking assembly 200 to move downward, the positioning column 230 of the material taking assembly 200 passes downward through the groove 12 of the rear cover 1 to realize the horizontal positioning of the groove 12, the second mounting block 312 of the claw assembly 300 is attached to the upper surface of the rear cover 1, the negative pressure suction head 240 holds the rear cover 1, the rear cover 1 material taking is completed, after the material taking is completed, the first X-axis module 120 and the servo driving part 150 cooperate to drive the rear cover 1 to move upward and move to the upper side of the shell 2;

[0066] First pressing: the servo driving part 150 drives the rear cover 1 to move downward by a first predetermined stroke, so that the buckle 11 of the rear cover 1 is at the same height position as the base part 21 of the shell 2, and then the telescopic part 330 extends by a second predetermined stroke, so that the second end 322 of the Y-shaped support 320 moves towards the buckle 11 and drives the buckle 11 to move towards the base part 21;

[0067] Judging whether the assembly is successful:

[0068] A. If all the sensors 340 of the claw assembly 300 have sensed the third end 323 of the Y-shaped bracket 320 (that is, the third end 323 passes through the sensor 340), it means that the second end 322 of all the Y-shaped brackets 320 has successfully pushed the buckle 11 into the base part 21. At this time, the assembly is determined to be successful and no further assembly is required.

[0069] B. If any of the sensors 340 fails to detect the third end 323 of the Y-shaped bracket 320, it means that at least one of the clips 11 has not been successfully assembled. In this case, the assembly is deemed to have failed and a second assembly is required.

[0070] Secondary assembly: All telescopic components 330 retract to their original positions. The servo drive 150 drives the rear cover 1 to continue moving downwards for a third predetermined stroke. The third predetermined stroke is much smaller than the first predetermined stroke, for example, the third predetermined stroke is 1% to 5% of the first predetermined stroke. Then, the telescopic component 330 extends again for a second predetermined stroke. The second end 322 of the Y-shaped bracket 320 moves toward the buckle 11 again and pushes the buckle 11 toward the base part 21. Finally, it is judged again whether the assembly is successful. This process is repeated. If the assembly is still unsuccessful after three attempts, an alarm program needs to be activated.

[0071] In this embodiment, during the secondary assembly, considering that the reason for the previous assembly failure was likely due to an error that caused the height of the buckle 11 to be slightly higher than the base part 21, it is only necessary to continue to move the back cover 1 downward slightly and then assemble it again during the secondary assembly.

[0072] Example 2:

[0073] like Figure 8 As shown in the figure, this embodiment 2 discloses a back cover pressing assembly, which includes a turntable 400, a three-axis feeding device 500, a pressing device, a laser marking device 600, and a detection device 800.

The turntable 400 is arranged with equal intervals around its circumference, including a housing loading station 400a, a pressing station 400b, a marking station 400c, and a unloading station 400d. The turntable 400 is also equipped with a positioning tool for horizontally limiting the housing 2 to be installed.
