[0015] The present invention will be further described in detail below with reference to specific embodiments.

[0016] Example:

[0017] like Figures 1 to 4 As shown, this utility model discloses a pre-assembly device for fully unlocked cover plates, including a machine base 1 and a servo turntable 2 mounted on the machine base 1. Multiple fixtures 3 for placing cover plates are distributed at equal angles on the turntable 2. Around the turntable 2, a spring positioning mechanism, a rubber pad feeding mechanism, a pressing mechanism, and an oil injection mechanism are distributed clockwise in sequence. A transfer mechanism is provided on the rubber pad feeding mechanism. The pressing mechanism includes a pressing cylinder 4 mounted on the machine base 1 via a bracket and a pressure head 5 connected to the output end of the pressing cylinder 4. The rubber pad feeding mechanism includes a vibrating plate 6 and a linear vibrating track 7. Two linear vibrating tracks 7 are arranged parallel to each other in a horizontal plane. A material-picking mechanism is provided at the end of the linear vibrating track 7. The material-picking mechanism includes a material-picking column 8 located at the end of the linear vibrating track 7. The material-picking column 8 is connected to a servo motor 9. The linear vibrating track 7 faces the circumference of the material-picking column 8. Multiple material-picking holes 10 are distributed on the circumference of the material-picking column 8.

[0018] The transfer mechanism includes a translation module 11 mounted above the material picking column 8 via a bracket. An L-shaped plate is connected to the translation module 11. A mounting plate 12 is rotatably connected to the lower end face of the L-shaped plate. The mounting plate 12 is driven by a second servo motor 13. Two lifting cylinders 14 are provided on the lower end face of the mounting plate 12. The output end of the lifting cylinders 14 is connected to a gripper 15.

[0019] The spring alignment mechanism includes a vertical plate mounted on a machine base 1. A slider 16 is slidably connected to the vertical plate via a slide rail. A lead screw 17 is vertically rotatable on the vertical plate via a bearing seat. The lead screw 17 is connected to the slider 16 via a lead screw nut. A third servo motor 18 is connected to the lead screw 17. A fourth servo motor 19 with its output end facing downwards is mounted on the slider 16. The output end of the fourth servo motor 19 is connected to an alignment head 20. The alignment head 20 is a segmented column with a thinner bottom and a thicker top.

[0020] The oil injection mechanism includes a nozzle 23 mounted on the machine base 1 via an XZ axis moving module 22, and the nozzle 23 is connected to an oil reservoir via a hose and an oil pump.

[0021] The working process of this utility model is as follows: A cover plate is placed inside the fixture 3. The cover plate has a pre-set spring mounting groove and two rubber pad mounting grooves. A spring is pre-installed in the spring mounting groove. The turntable 2 rotates clockwise under the drive of a motor to the bottom of the spring alignment mechanism. The third servo motor 18 drives the lead screw 17 to rotate, thereby driving the alignment head 20 downwards. The bottom end of the alignment head 20 extends into the inner ring of the spring. The fourth servo motor 19 drives the alignment head 20 to rotate. The side of the alignment notch 21 abuts against the end of the spring, thereby pushing the spring to rotate. The spring mounting groove has a matching spiral indentation, so that the alignment head 20 drives the spring to rotate and be installed in place. After the spring is aligned, the third servo motor 18 drives the alignment head 20 to reset. The fixture 3 then... Rotating to below the transfer mechanism, the vibratory feeder 6 simultaneously delivers two rows of rubber pads to the picking column 8 via two linear vibrating tracks 7. The foremost rubber pad is delivered into the picking hole 10 on the picking column 8. The servo motor 9 drives the picking column 8 to rotate, causing the picking hole 10 containing the rubber pad to face upwards. The transfer mechanism transfers the two rubber pads into the rubber pad mounting holes on the cover plate. The fixture 3 then rotates to below the pressing mechanism to press the two rubber pads into place. The fixture 3 continues to rotate to below the oiling mechanism. Driven by the XZ axis moving module 22, the nozzle 23 extends into the spring mounting hole to spray lubricating oil. After oiling is completed, the XZ axis moving module 22 drives the nozzle 23 to reset. The fixture 3 continues to rotate to the initial position, removes the pre-assembled cover plate, and places the next cover plate on top.

[0022] The above descriptions are merely some embodiments of this utility model.
