The existing technology is to set up a pipeline, and a tooling plate is placed on the pipeline. The household appliance assembly is inverted on the tooling plate. The household appliance assemblies in a row move on the pipeline. When the household appliance assembly reaches the corresponding position below the automatic screw locking mechanism, the corresponding tooling plate is stopped. Through the positioning effect of the tooling plate on the household appliance assembly, the automatic screw locking mechanism can accurately install each screw on the household appliance assembly.

(As shown) Figures 1 to 3 As shown, the automated screw assembly equipment of the present invention further includes an in-machine conveyor roller assembly 3 for transferring the assembly part 99 to the corresponding area below the automatic screw fastening mechanism 5, such as... Figure 6 As shown, the in-machine conveyor roller assembly 3 includes conveyor rollers 31 arranged longitudinally and a conveyor roller drive motor 32 for driving the conveyor rollers 31 to rotate. The conveyor roller drive motor 32 drives each conveyor roller 31 to rotate via a chain. The in-machine conveyor roller assembly 3 can convey the assembly 99 longitudinally, and a roller gap 311 is formed between adjacent conveyor rollers 31.

[0026] like Figures 1 to 3 As shown, the automated screw assembly line of the present invention further includes an infeed top-feeding mechanism 2 for moving the assembly part 99 onto the in-machine conveyor roller assembly 3 and an outfeed top-feeding mechanism 20 for moving the assembly part 99 away from the in-machine conveyor roller assembly 3. Figure 5 As shown, the top feeding mechanism 2 is equipped with a feed transverse conveyor belt 21 and a feed transverse conveyor motor 22 for driving the feed transverse conveyor belt 21. The feed transverse conveyor belt 21 extends in the front-to-back direction. For example, there are four feed transverse conveyor belts 21, which are arranged at intervals. The feed transverse conveyor motor 22 drives all four feed transverse conveyor belts 21 simultaneously via a chain. Figure 3 As shown, the feed transverse conveyor belt 21 is positioned within the corresponding roller gap 311, as...Figure 5 As shown, the feeding top conveyor mechanism 2 is equipped with a feeding conveyor belt lifting cylinder 23. The feeding conveyor belt lifting cylinder 23 drives the feeding transverse conveyor belt 21 to move up and down. Specifically, the feeding top conveyor mechanism 2 is equipped with a conveyor belt bracket. The feeding transverse conveyor belt 21 and the feeding transverse conveyor motor 22 are installed on the aforementioned conveyor belt bracket. The aforementioned conveyor belt bracket is slidably arranged up and down. The feeding conveyor belt lifting cylinder 23 is located on the lower side of the aforementioned conveyor belt bracket. The piston rod of the feeding conveyor belt lifting cylinder 23 is connected to the aforementioned conveyor belt bracket. The discharge top conveyor mechanism 20 is equipped with a discharge transverse conveyor belt and a discharge transverse conveyor motor for driving the discharge transverse conveyor belt. The discharge transverse conveyor belt is located within the corresponding roller gap 311. The discharge top conveyor mechanism 20 is equipped with a discharge conveyor belt lifting cylinder, which drives the discharge transverse conveyor belt to move up and down. The structural principle of the discharge top conveyor mechanism 20 is the same as that of the infeed top conveyor mechanism 2, so it will not be described in detail. The discharge top conveyor mechanism 20 is located in front of the infeed top conveyor mechanism 2 in the direction of the conveying assembly 99, but in... Figure 3 From the visual direction, the discharge top conveyor 20 is located to the left of the infeed top conveyor 2.

[0027] like Figures 1 to 3 As shown, the automated screw assembly equipment of the present invention further includes a flat conveying mechanism 1 for conveying the assembly parts 99 to the infeed transverse conveyor belt 21 or receiving the assembly parts 99 conveyed by the outfeed transverse conveyor belt, such as... Figure 1 and Figure 4 As shown, the flat conveyor mechanism 1 is equipped with an inlet / outlet conveyor belt 11 located above the corresponding part of the assembly line device 9. The flat conveyor mechanism 1 is equipped with an inlet / outlet conveyor motor 12, which drives the inlet / outlet conveyor belt 11 to rotate. Specifically, there are two inlet / outlet conveyor belts 11, which are arranged separately on the left and right sides. The two inlet / outlet conveyor belts 11 are respectively connected to the left and right ends of the drive shaft through corresponding synchronous pulleys. The inlet / outlet conveyor motor 12 drives the drive shaft to rotate through a chain. Figure 3 As shown, the horizontal conveying mechanism 1 is equipped with a longitudinal transfer cylinder 14, which is mounted on the frame. The longitudinal transfer cylinder 14 drives the inbound and outbound transfer conveyor belt 11 and the inbound and outbound transfer motor 12 to move longitudinally. Specifically, the horizontal conveying mechanism 1 is equipped with a translation frame, on which the inbound and outbound transfer conveyor belt 11 and the inbound and outbound transfer motor 12 are mounted. The translation frame is slidably connected to the front side of the frame through a linear guide rail. Thus, the translation frame is suspended on one side, allowing the inbound and outbound transfer conveyor belt 11 to be positioned above the corresponding part of the assembly line device 9. The piston rod of the longitudinal transfer cylinder 14 is connected to the translation frame.

[0028] The working principle of the automated screw assembly line of the present invention is briefly described below: Figure 9As shown, two tooling plates 98 are provided for accommodating the positioning and assembling of the assembling parts 99, one tooling plate 98 is located on the in-out transfer conveyor 11, and the assembling parts 99 are slowly conveyed to the left by the assembly line device 9, when one assembling part 99 moves to the right side of the assembly line automatic screw assembling device of the present application, the operator takes up the assembling part 99 and places it on the tooling plate 98 located on the in-out transfer conveyor 11 (of course, an industrial robot can also be provided to take up the assembling part 99 and place it on the tooling plate 98), as shown in Figure 4 As shown, the translation frame of the horizontal conveying mechanism 1 is provided with a feeding probe 15, which is a reflection type photoelectric sensor, when the assembling part 99 is placed on the tooling plate 98, the assembling part 99 triggers the feeding probe 15, and the control system automatically controls the in-feed conveyor lifting cylinder 23 to lift the in-feed horizontal transfer conveyor 21, the in-feed horizontal transfer conveyor 21 operates, the control system starts the in-out transfer motor 12 to make the in-out transfer conveyor 11 operate to drive the tooling plate 98 and the assembling part 99 to move backward together, so that the rear end of the tooling plate 98 reaches the in-feed horizontal transfer conveyor 21, and the tooling plate 98 is then transferred backward by the in-feed horizontal transfer conveyor 21, in other words, the in-out transfer conveyor 11 delivers the tooling plate 98 and the assembling part 99 to the in-feed horizontal transfer conveyor 21, and the tooling plate 98 moves backward to the rear positioning back plate 801; as shown in Figure 4 As shown, the horizontal conveying mechanism 1 is provided with an in-out feeding probe 13, since the in-out feeding probe 13 is triggered by the assembling part 99, it represents that the assembling part 99 has been transferred to the in-feed horizontal transfer conveyor 21, so the control system controls the longitudinal transfer cylinder 14 to drive the in-out transfer conveyor 11 to move to the front of the out-feed horizontal transfer conveyor according to the signal of the in-out feeding probe 13; the in-feed conveyor lifting cylinder 23 lowers the in-feed horizontal transfer conveyor 21, since the in-feed horizontal transfer conveyor 21 is located in the corresponding roller gap 311, when the in-feed horizontal transfer conveyor 21 is lowered to the lower side of the conveying roller 31, the tooling plate 98 falls on the conveying roller 31, and then the conveying roller 31 drives the tooling plate 98 and the assembling part 99 to move to the corresponding lower side of the automatic screw locking mechanism 5, as shown in Figure 3As shown, specifically, the tooling plate 98 reaches the left positioning back plate 802, and the longitudinal positioning cylinder 81 presses the tooling plate 98 against the right side of the left positioning back plate 802, and the transverse positioning cylinder 82 presses the tooling plate 98 against the front side of the rear positioning back plate 801, both the longitudinal positioning cylinder 81 and the transverse positioning cylinder 82 can be a rotary clamping cylinder (or called "rotary down-pressing cylinder") on the market, so that the tooling plate 98 is completely positioned in the horizontal plane, the automatic screw locking mechanism 5 is provided with a screwdriver head (also called "batch head") capable of moving downward while rotating, so that the automatic screw locking mechanism 5 can install the screw sent through the pipeline on the assembly part 99, after the screw is assembled, the control system controls the discharge conveying belt lifting cylinder of the discharge top feeding mechanism 20 to lift the discharge transverse conveying belt, so that the discharge transverse conveying belt pushes up the tooling plate 98 and the assembly part 99 with the assembled screw, and then the discharge transverse conveying belt operates to move the tooling plate 98 and the assembly part 99 with the assembled screw forward to the in-out transfer conveying belt 11, the in-out probe 13 is triggered, and then the discharge transverse conveying belt is lowered and stopped operating, another tooling plate 98 with the next assembly part 99 placed thereon is transferred to the corresponding position below the automatic screw locking mechanism 5 by the conveying roller 31, at the same time, for example, an operator or an industrial robot puts the assembly part 99 with the assembled screw back on the assembly line device 9, and then because the in-feed probe 15 is disconnected, the control system controls the longitudinal transfer cylinder 14 to drive the in-out transfer conveying belt 11 to move rightward to reset according to the disconnection signal of the in-feed probe 15, because the assembly part 99 with the previously assembled screw has been taken away, the tooling plate 98 remains on the in-out transfer conveying belt 11; the above-mentioned cycle is repeated. As known from the above, the assembly line automatic screw assembling equipment of the present application only needs to set two tooling plates 98 to realize the cycle, and only needs to place a set of the assembly line automatic screw assembling equipment of the present application beside the assembly line device 9 to realize the screw assembling process on the assembly part 99 continuously conveyed on the assembly line device 9, avoiding the need to arrange a tooling plate cycle conveying line with a large floor area in the factory, thereby being beneficial to reduce the cost and beneficial to reduce the space occupied in the factory.

When the assembly part 99 is assembled with the screw, the discharge top feeding mechanism 20 moves the assembly part 99 forward to the in-out transfer conveying belt 11, the assembly part 99 triggers the in-out feeding probe 13, the control system controls the clamping arms 42 to move downward, and the clamping arms 42 clamp the assembly part 99 which has been assembled with the screw, the control system controls the clamping arm lifting motors 44 to lift the assembly part 99 away from the flat conveying mechanism 1, the in-out feeding probe 13 is disconnected, the control system moves the in-out transfer conveying belt 11 to the right to reset, and the control system controls the clamping arm lifting motors 44 to put down the assembly part 99 on the assembly line device 9. Figure 7 As shown, the lower mechanism 4 is provided with a position monitoring probe 49, which is a reflection type photoelectric sensor, when the assembly part 99 triggers the position monitoring probe 49, the control system controls the clamping arm cylinders 43 to drive the clamping arms 42 to move close to each other, the clamping arms 42 clamp the assembly part 99 which has been assembled with the screw, the control system controls the clamping arm lifting motors 44 to lift the assembly part 99 away from the flat conveying mechanism 1, the in-out feeding probe 13 is disconnected, the control system moves the in-out transfer conveying belt 11 to the right to reset, and the control system controls the clamping arm lifting motors 44 to put down the assembly part 99 on the assembly line device 9.
