[0036] The displacement mechanism includes an upper plate 10 and a lower plate 11, a rectangular frame 7 is slidably connected to the inner side of the U-shaped plate 40, the transfer frame 9 is arranged above the rectangular frame 7, and the uppermost placement table of the transfer frame 9 is flush with the surface of the unloading conveyor line 5, the upper plate 10 and the lower plate 11 are respectively arranged at the upper and lower ends of the inner side of the rectangular frame 7, the side wall of the bottom end of the L-shaped plate 13 is slidably connected to the L-shaped rod 22, the side wall of the L-shaped rod 22 is connected to the side plate 23 by bolts, and the top of the side plate 23 is slidably connected to the guide rod 24, a plurality of straight grooves 25 are equidistantly provided at the bottom end of the upper plate 10, and upper inclined grooves 26 are provided between the plurality of straight grooves 25, a lower inclined groove 27 is provided at the top end of the lower plate 11 and away from the L-shaped frame 8 and at a position corresponding to the lower side of the upper inclined groove 26, and the lower inclined groove 27 is inclinedly provided close to one side of the L-shaped frame 8, and the top of the guide rod 24 is provided on the inner side of the straight groove 25.

[0037] A return spring 28 is fixedly connected between the outer wall of the guide rod 24 and the top of the side plate 23. The setting of the return spring 28 facilitates the guide rod 24 to be pushed into the specified position, and the bottom end of the guide rod 24 is set to a smooth arc surface. A return slant groove 29 is opened at the top of the lower plate 11, and the two ends of the return slant groove 29 are connected to the two ends of the outermost straight groove 25. The tops of both sides of the inner wall of the return slant groove 29 are fixedly connected with guide plates 30. The setting of the guide plates 30 prevents the guide rod 24 from falling into the return slant groove 29 when it slides out of the lower slant groove 27. In the middle, there is a gap between the guide plates 30, and a slide groove 31 is provided on the outer wall of the guide rod 24 and at a position corresponding to the guide plate 30. The slide groove 31 is provided to facilitate the guide rod 24 to slide over the guide plate 30 to avoid affecting the normal operation of the device. A lower groove 32 adapted to the straight groove 25 is provided at one end of the bottom of the reset inclined groove 29, and the end of the lower groove 32 is inclined. A touch sensor 33 is fixedly connected to the other end of the bottom of the reset inclined groove 29, and the touch sensor 33 is convenient for automatically controlling the operation of the height adjustment mechanism;

[0038] In order to improve the convenience of the device, an inclined plate 34 is inserted into the side wall of the rectangular frame 7. The setting of the inclined plate 34 makes it convenient for the staff to push the transfer rack 9 to the top of the rectangular frame 7, thereby improving the convenience of the device. A U-shaped baffle 35 is fixedly connected to the top of the rectangular frame 7. The U-shaped baffle 35 can be used to limit the moving position of the transfer rack 9 to ensure stability during the unloading process. A pair of arc grooves 36 are provided on the top of the rectangular frame 7. The setting of the arc grooves 36 can limit the position of the rollers below the transfer rack 9 to avoid the rollers from moving randomly during the rising process, thereby improving the stability of the device during operation.

[0039] In order to automatically adjust the height of the transfer rack 9 to align with the unloading conveyor line 5 after each layer is placed on the transfer rack 9, the height adjustment mechanism includes a drive motor 38, a pair of drive motors 38 are provided, and the inner sides of both ends of the fixed rack 6 are rotatably connected with threaded rods 39, the drive motors 38 are fixedly connected to the top of the fixed rack 6, the output end of the drive motor 38 passes through the top of the fixed rack 6 and is fixedly connected to the top of the threaded rod 39, the U-shaped plate 40 is fixedly connected with sliding plates 41 on both sides, and the outer walls of the threaded rods 39 are threadedly connected to the inner top of the sliding plate 41;

[0040] When the transfer rack 9 is full of inverters, the guide rod 24 will move to the end of the last straight groove 25, and then push the guide rod 24 into the reset inclined groove 29 at the bottom under the elastic force of the reset spring 28, thereby touching the touch sensor 33, and then the touch sensor 33 transmits a signal to the controller, and the controller controls the drive motor 38 to start and drive the threaded rod 39 to rotate, thereby driving the threaded sliding plate 41 to move, and at the same time driving the U-shaped plate 40 and the rectangular frame 7 to move upward, and the lower plate 11 will push the guide rod 24 to move upward, thereby driving the L-shaped rod 22 to slide on the side wall of the L-shaped plate 13, thereby realizing the adjustment of the height position of the transfer rack 9, which can ensure that the transfer rack 9 automatically rises after each layer is full, and realizes full-automatic unloading of the device (it should be noted here that the drive motor 38 is a servo motor, and then the controller sets the distance parameters for each drive, so that each layer of the transfer rack 9 can be automatically raised to the side of the unloading conveyor line 5), and finally, after the transfer rack 9 is completely swung, the reverse control of the drive motor 38 is used to start driving the U-shaped plate 40 to descend and reset.

[0041] In order to be able to replace the corresponding upper plate 10 and lower plate 11 according to the size of the inverter and change the distance of each pulling of the rectangular frame 7, a limit frame 43 is fixedly connected to both sides of the inner wall of the rectangular frame 7 and is located between the upper plate 10 and the lower plate 11, and the upper and lower ends of the limit frame 43 are respectively penetrated and slidably connected with an L-shaped positioning plate 44, and a socket 45 is opened at a position corresponding to the L-shaped positioning plate 44 on one side of the upper plate 10 and the lower plate 11, and the ends of the L-shaped positioning plate 44 are plugged into the inner side of the socket 45, and a connecting plate 42 is fixedly connected between the upper plate 10 and the lower plate 11, and a limit spring 37 is fixedly connected between the inner side of the limit frame 43 and the outer wall of the L-shaped positioning plate 44;

[0042] By pulling the inclined plate 34 out from the side wall of the rectangular frame 7 and then pushing the L-shaped positioning plates 44 on both sides to slide out of the sockets 45 and compressing the limit springs 37 at the same time, the position restriction on the upper plate 10 and the lower plate 11 can be released. At the same time, the bolts on the side plates 23 and the L-shaped rods 22 can be unscrewed to release the position restriction on the side plates 23. Then, the connecting plate 42 can be pulled out to pull the upper plate 10 and the lower plate 11 out, and then the upper plate 10 and the lower plate 11 with straight grooves 25 with different gaps can be replaced. The above operation can be repeated in reverse to install the upper plate 10 and the lower plate 11 back, thereby changing the upper plate 10 and the lower plate 11 with straight grooves 25 with different gaps, and the distance of pulling the rectangular frame 7 each time can be changed, so that inverters of different sizes can be neatly placed on the transfer rack 9, thereby improving the scope of application of the device.

[0043] During the process of assembling the frequency converter, the assembled frequency converter is swung on the unloading conveyor line 5 in sequence by the unloading robot arm 4, and then the frequency converter is transported to the bottom of the L-shaped frame 8 through the unloading conveyor line 5, and then the electric telescopic cylinder 12 is controlled to start pushing the L-shaped plate 13 to slide, thereby driving the rectangular plate 17 to slide, and the inclined surface of the side wall of the rectangular plate 17 squeezes the inclined surface of the right-angle block 16, so that the right-angle block 16 slides downward, and then pushes the partition plate 14 to slide downward, separating the frequency converter on the unloading conveyor line 5, and then the rectangular plate 17 continues to move, and the right-angle block 16 is against the bottom of the rectangular plate 17, and at the same time, the rectangular plate 17 pushes the moving plate 20 to move, thereby driving the U-shaped frame 19 and the push plate 15 to slide, thereby pushing the separated frequency converter, and pushing the frequency converter to the transfer rack 9;

[0044] At the same time, the movement of the L-shaped plate 13 will drive the L-shaped rod 22 to move, thereby causing the side plate 23 to slide between the upper plate 10 and the lower plate 11, and at the same time drive the guide rod 24 to gradually slide out of the lower groove 32, and squeeze the guide rod 24 to slide upward into the inner side of the straight groove 25 below the upper plate 10, while stretching the return spring 28, and then the guide rod 24 slides in the straight groove 25 under the push of the L-shaped rod 22, and then when the push plate 15 pushes the inverter completely onto the transfer rack 9, the guide rod 24 moves to the top of the lower inclined groove 27, and then the guide rod 24 is pushed to slide into the lower inclined groove 27 under the elastic force of the return spring 28, and then the electric telescopic cylinder 12 drives the rectangular plate 17 to reset, and at the same time gradually pulls back the push plate 15 under the elastic force of the lower spring 21;

[0045] At the same time, the L-shaped rod 22 drives the side plate 23 and the guide rod 24 to reset. At this time, the guide rod 24 is inserted in the lower inclined groove 27, and then under the pulling force of the guide rod 24, the rectangular frame 7 will be squeezed to slide on the U-shaped plate 40, so that the inverter just pushed in is moved out of the unloading conveyor line 5. Then the L-shaped plate 13 is reset, and the guide rod 24 slides out of the upper inclined groove 26 at this time. At the same time, the right-angle block 16 loses the squeezing of the rectangular plate 17, and pushes the partition 14 back under the elastic force of the upper spring 18. Then the inverter on the unloading conveyor line 5 continues to be transported forward, and this is repeated, and the inverters are placed on the transfer rack 9 in turn. Then when the upper layer of the transfer rack 9 is full, the guide rod 24 will slide to the end of the last straight groove 25. At this time, the guide rod 24 moves to the top of the reset inclined groove 29, and then the guide rod 24 is pushed into the reset inclined groove 29 under the elastic force of the reset spring 28, and the top of the guide rod 24 slides out of the straight groove 25. The touch sensor 33 is touched at the same time, and the touch sensor 33 controls the height adjustment mechanism to operate through the controller. Subsequently, when the electric telescopic cylinder 12 is reset, the side plate 23 and the guide rod 24 are pulled to reset through the L-shaped rod 22, so that the guide rod 24 moves inside the reset chute 29, gradually squeezing the rectangular frame 7 to reset, and then the slide groove 31 on the guide rod 24 moves to the guide plate 30, and finally the guide rod 24 moves to the top of the lower groove 32 at the other end of the reset chute 29, and under the elastic force of the reset spring 28, the guide rod 24 will be pushed to continue to slide downward into the lower groove 32. Since there is a step between the lower groove 32 and the reset chute 29, it is restricted. At this time, the upper and lower layers of the transfer rack 9 move to the side of the unloading conveyor line 5, and this is repeated, and the assembled inverters can be automatically placed on the transfer rack 9 in sequence without the need for workers to place them, saving time and effort, and improving the convenience of the device.
