[0029] The vertical plate is equipped with an assembly mechanism that has a multi-stage electric push rod 11 to push the assemblies of the pads. The assembly mechanism includes a connecting ring 12 and a push cylinder 13, with the push cylinder 13 fixedly connected to the connecting ring 12.

[0030] Please see Figure 2 A motor 2 is fixedly connected to the top surface of the base plate 1. An "L"-shaped rod 62 is fixedly connected to one side of the base plate 1. A limit ring 6 is fixedly connected to one end of the "L"-shaped rod 62. A screw turntable 3 is rotatably connected to the limit ring 6. Multiple through holes are opened in a ring array on the screw turntable 3. A "T"-shaped placement cylinder 7 is fixedly connected to the limit ring 6. Screws 15 are placed in the "T"-shaped placement cylinder 7. The "T"-shaped placement cylinder 7 is placed vertically and the screws 15 are stacked from top to bottom. As the motor 2 drives the screw turntable 3 to rotate, the stacked screws 15 fall into the through holes one by one as the screw turntable 3 rotates.

[0031] Please see Figure 2 One side of the limiting ring 6 is fixedly connected to multiple connecting posts 60, and the multiple connecting posts 60 are fixedly connected to an anti-offset ring 61. One side of the anti-offset ring 61 is attached to the stud head of the screw 15. In order to prevent the screw 15 from moving towards the motor 2 in the through hole of the screw turntable 3, the anti-offset ring 61 can prevent the screw 15 from shifting to one side.

[0032] Please see Figure 3 One end of the screw turntable 3 is fixedly connected to a fixing rod 4, and the other end of the fixing rod 4 is fixedly connected to a washer turntable 5. The washer turntable 5 has multiple through holes arranged in a circular array at equal intervals. The washer turntable 5 is rotatably connected to a ring 8. The top of the ring 8 is fixedly connected to a washer placement cylinder 9. The washer placement cylinder 9 has an "I"-shaped placement groove 90. Flat pads 150 and spring pads 151 are placed in the "I"-shaped placement groove 90 from top to bottom. Multiple flat pads 150 and spring pads 151 are placed in the "I"-shaped placement groove 90 in sequence. As the washer turntable 5 rotates, they automatically fall into the through holes, thus avoiding the laborious task of manual placement.

[0033] Please see Figure 2 A vertical rod 80 is fixedly connected to the outer wall of the ring 8. A base plate 10 is fixedly connected to the bottom surface of the vertical rod 80. A vertical plate is fixedly connected to the base plate 10. The input end of a multi-stage electric push rod 11 is fixedly connected to the vertical plate.

[0034] Please see Figure 4 The flat washer 150 and spring washer 151 in the washer turntable 5 are located between the push cylinder 13 and the screw 15, respectively. By restricting them with the push cylinder 13 and the screw 15, the flat washer 150 and spring washer 151 in the washer turntable 5 can be prevented from falling to the left or right.

[0035] Please see Figure 1 The base plate 1 and the base plate 2 10 are fixedly connected to the two sides of the placement plate 14. The placement plate 14 is provided with a screw head placement groove 140 and a washer placement groove 141. The screw head of the screw 15 is placed in the screw head placement groove 140, and the flat washer 150 and the spring washer 151 are placed in the washer placement groove 141. The purpose of setting the screw head placement groove 140 is to prevent the screw 15 from shifting when it slides down, and the purpose of setting the washer placement groove 141 is to prevent the assembled screw head placement groove 140 and washer placement groove 141 from falling apart. The motor 2 and the multi-stage electric push rod 11 are both connected to an external power supply. The working stroke of the motor 2 and the multi-stage electric push rod 11 are both controlled by the controller.

[0036] The implementation principle of the device for assembling and combining self-tapping screws in this application embodiment is as follows:

[0037] Multiple screws 15 are vertically placed in the "T"-shaped placement cylinder 7, and flat washers 150 and spring washers 151 are vertically placed in the washer placement cylinder 9. Only by starting the motor 2, the motor 2 drives the screw turntable 3, the fixing rod 4 and the washer turntable 5 to rotate. A flat washer 150, a flat washer 150 and a spring washer 151 will fall out of the through holes of the screw turntable 3 and the washer turntable 5. At this time, the flat washer 150 and the spring washer 151 are limited by the screw 15 and the push cylinder 13.

[0038] After the motor 2 rotates to a certain angle, a certain number of screws 15, flat washers 150, and spring washers 151 are placed in the screw turntable 3 and the washer turntable 5, as shown in the attached diagram of the instruction manual. Figure 2 The state shown.

[0039] When motor 2 stops rotating, the output end of multi-stage electric push rod 11 is pushed out from the input end and drives push cylinder 13 to move toward screw 15. Push cylinder 13 is inserted into the through hole of gasket turntable 5 and puts flat gasket 150 and spring gasket 151 on screw 15.

[0040] The multi-stage electric push rod 11 is reset, and the motor 2 is turned on to continue driving the screw turntable 3, the fixing rod 4 and the washer turntable 5 to rotate. At this time, as the screw turntable 3 continues to rotate, the assembled screw 15 falls into the placement plate 14 and slides down.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
