Description

Technical Field

[0001] The invention relates to an assembly production line, in particular to a fully automatic assembly production line for miniature circuit breakers. Background Art

[0002] Miniature circuit breakers are electrical devices used for overload and short circuit protection. They are usually installed in distribution boxes in homes, offices or industrial facilities to protect circuits from overcurrent damage. When the current exceeds a preset value, the miniature circuit breaker will automatically disconnect and cut off the power supply, thereby preventing accidents such as fire. Miniature circuit breakers include a housing and nuts, screws, magnets, magnetic plates, arc extinguishing chambers, small U, trip buckles, torsion springs, handles, large U, etc. installed in the housing. Since many components need to be installed, manual installation will result in low work efficiency and prone to installation errors. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide a fully automatic assembly production line for miniature circuit breakers.

The shell splitting device is used to split the shell into an upper shell and a lower shell, and the lower shell is transmitted to the conveying device, and the upper shell is transmitted to the upper shell installation device; the nut and screw feeding device is used to feed nuts and screws into the lower shell corresponding to the conveying device and install Installation; Magnetic feeder: feed the magnetic feeder into the lower shell corresponding to the conveying device and install it; Magnetic plate feeder: feed the magnetic plate into the lower shell corresponding to the conveying device and install it; Arc extinguishing chamber feeder: feed the arc extinguishing chamber into the lower shell corresponding to the conveying device and install it; Small U feeder: feed the small U into the lower shell corresponding to the conveying device and install it; Jump buckle feeder: feed the jump buckle into the lower shell corresponding to the conveying device and install it; Torsion spring feeder: feed the torsion spring into the lower shell corresponding to the conveying device and install it; Handle feeder: feed the handle into the lower shell corresponding to the conveying device and install it ; Large U loading device: loads the large U into the lower shell corresponding to the conveying device and installs it; upper shell installation device: receives the upper shell and loads the upper shell onto the lower shell corresponding to the conveying device for installation; unloading device: unloads the assembled product; the shell separation device includes a shell loading mechanism, a shell conveyor belt, an upper dumping plate, a lower dumping plate, an upper shell conveyor belt, a lower shell conveyor belt, and a separation clamp. The shell loading mechanism loads the shell onto the shell conveyor belt. The upper dumping plate is arranged on one side of the shell conveyor belt, and the lower dumping plate is arranged on the other side of the shell conveyor belt and is opposite to the upper dumping plate. The upper dumping plate is vertically high. The height is higher than the height of the lower dumping plate in the vertical direction, and an inclined dumping track is provided between the upper dumping plate and the lower dumping plate. The separation clamp is provided at the end of the shell conveyor belt. The separation clamp splits the shell into an upper shell and a lower shell and clamps them to the upper shell conveyor belt and the lower shell conveyor belt respectively. One end of the upper shell conveyor belt is opposite to the shell conveyor belt, and the other end is opposite to the conveying device. One end of the lower shell conveyor belt is opposite to the shell conveyor belt, and the other end is opposite to the upper shell mounting device. Manual assembly can be performed on the lower shell conveyor belt, so that some components that cannot be assembled by machinery can be assembled manually, and the conveying device is a conventional conveyor belt.

[0005] By adopting the above technical scheme, when the product needs to be assembled, the shell is first transferred to the shell conveyor belt by the shell loading mechanism, and then moves on the shell conveyor belt, and then the shell moves into the unloading track. Since the unloading track is inclined and the upper unloading plate and the lower unloading plate are at different heights, the shell changes from a vertical position to a lying position, and then enters the upper shell conveyor belt and the lower shell conveyor belt respectively under the clamping of the separation clamp, and the lower shell conveyor belt is then transferred to the conveying device, and then the nuts, screws, magnets, magnetic plates, arc extinguishing chambers, small U, jump buckles, torsion springs, handles, and large U are loaded and assembled in turn, and then the upper shell installation device receives the upper shell and installs the upper shell on the lower shell, and finally unloads. By first unloading the shell and then transferring it to the upper shell conveyor belt and the lower shell conveyor belt respectively, the lower shell receives the assembly of various components, and finally installs it with the upper shell, and finally unloads, which reduces the degree of manual participation, has a high degree of automation, high work efficiency, and low error.

The installation motor is arranged at the installation station and has an installation state of driving the installation rod to install the screws and nuts. The nut and screw moving mechanism is arranged at the moving station and has a moving state of moving the nuts and screws to the conveying device. The structure of the nut feeding mechanism is generally the same as that of the screw feeding, so it will not be described again. The structure of other feeding devices is also generally the same as that of the nut feeding mechanism. The material is basically loaded by a vibrating plate, then transferred to the track, divided by dislocation, and finally clamped by clamps.

[0007] By adopting the above technical scheme, when it is necessary to assemble nuts and screws, the nut feeding mechanism loads the nuts into the carrier, and the rotating disk rotates to move the carrier to a position opposite to the pushing track, that is, the screw loading station, and then the screw vibration disk transfers the screw to the screw feeding track until the screw enters the moving through groove in the screw dislocation block, and the screw dislocation cylinder drives the screw dislocation block to move along the connecting track until it moves to the moving through groove opposite to the pushing track, and then the pushing cylinder drives the pushing block to push the screw along the pushing track, directly rotating the disk into the corresponding carrier and against the nut, and then the rotating disk continues to rotate, so that the carrier moves to the installation position, and then the installation motor drives the installation rod to assemble the screw and the nut, and then the rotating disk drives the carrier to move to the material transfer station, and the nut and screw material transfer mechanism moves it to the conveying device and installs it in the corresponding lower shell.

[0009] By adopting the above technical solution, when the magnetic plate needs to be fed, the magnetic plate vibration plate feeds the magnetic plate to the magnetic plate feeding track until the magnetic plate enters the rotating groove of the rotating block, and then the magnetic plate rotating motor drives the rotating block to rotate, so that the rotating groove rotates to the feeding position relative to the magnetic plate moving mechanism, and then the magnetic plate moving mechanism transfers the magnetic plate to the lower shell of the corresponding conveying device and installs it.

[0010] The present invention is further configured as follows: the upper shell installation device includes a receiving conveyor belt, a flip motor, a flip block, a transmission cylinder and an installation clamp, the flip block is arranged between the upper shell conveyor belt and the receiving conveyor belt and is driven by the flip motor, and the flip block has a left groove opposite to the upper shell conveyor belt and a right groove opposite to the receiving conveyor belt on both sides, the transmission cylinder has a transmission state that pushes the upper shell from the flip block to the receiving conveyor belt, and the installation clamp is arranged between the receiving conveyor belt and the conveying device and installs the upper shell on the corresponding lower shell.

[0011] By adopting the above technical solution, since the front and back sides of the upper shell are the same as the lower shell after passing through the shell splitting device, the upper shell needs to be flipped. When the upper shell conveyor belt conveys the upper shell to the flip block and enters the left groove, the flip block is flipped 180 degrees under the action of the flip motor. At this time, the left groove is opposite to the receiving conveyor belt, and then enters the receiving conveyor belt under the action of the conveying cylinder, and then the upper shell is installed by the installation clamp.
