[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 This is a schematic diagram of the automatic unloading device for motor stator sector laminations of this utility model. It includes a frame 7, on which a magnetic conveyor belt 6 for conveying painted sector laminations is mounted. A stacking pallet (not shown) is located below the output end of the magnetic conveyor belt 6 to receive the painted sector laminations. The frame 7 is equipped with a photoelectric switch 5 and a reflector 1 corresponding to the output end of the magnetic conveyor belt 6, with the photoelectric switch 5 and reflector 1 positioned opposite each other. The magnetic conveyor belt 6, photoelectric switch 5, and reflector 1 are all electrically connected to a PLC controller (not shown). The photoelectric switch 5 and reflector 1 automatically track the painted sector laminations and send a signal upon reaching the output end of the magnetic conveyor belt 6, demagnetizing the magnetic conveyor belt 6. The painted sector laminations then fall onto the stacking pallet, achieving automatic unloading.

[0017] Furthermore, a guide baffle 4 is provided at the output end of the magnetic conveyor belt 6. The outlet position of the guide baffle 4 corresponds to the position of the stacking pallet, guiding the painted fan-shaped punches to fall accurately into the stacking pallet below. The guide baffle 4 is preferably composed of a left baffle and a rear baffle, which are identical in shape and symmetrically arranged to form an enveloping falling path, making the falling path of the painted fan-shaped punches unique and further improving the material unloading efficiency.

[0018] In order to facilitate the smooth falling of the painted fan-shaped punch into the falling path of the guide baffle 4, the inlet diameter of the guide baffle 4 is larger than the outlet diameter, so that the painted fan-shaped punch can fall accurately into the falling path of the guide baffle 4.

[0019] Furthermore, it also includes a vibrator 2 located on one side of the outlet of the guide baffle 4. The vibrator 2 is connected to a pneumatic reversing valve (not shown in the figure) via an air pipe 3. The pneumatic reversing valve is electrically connected to a PLC controller, which controls the air supply. Preferably, the vibration frequency of the vibrator 2 is adjustable, with an adjustment range of 5-20Hz. The vibrator 2 starts vibrating at a certain frequency to align and stack the fan-shaped stampings, ensuring that the vibration frequency of the vibrator does not cause scratches to the paint film.

[0020] In this embodiment, the photoelectric switch 5 is a diffuse reflection switch, which corresponds to the falling path of the fan-shaped punch and the position of the pallet, and accurately detects the falling position of the fan-shaped punch.

[0021] In this embodiment, a hydraulic lifting platform electrically connected to a PLC controller is also provided below the stacking pallet. The photoelectric switch 5 automatically tracks the stacking height and sends a signal to the PLC controller to control the hydraulic lifting platform to rise and fall, ensuring that the receiving height can accurately count the number of sector-shaped punches. When the number reaches a preset threshold, the PLC controller sends a stop signal to the magnetic conveyor belt 6 to stop the conveying.

[0022] The working principle of this utility model is as follows: After being painted, the fan-shaped punches are conveyed by the magnetic conveyor belt 6. When they reach the output end, i.e., the unloading station, the photoelectric switch 5 and the reflector 1 work together to detect the position of the painted fan-shaped punches and send a signal to the PLC controller. After receiving the signal, the PLC controller demagnetizes the magnetic conveyor belt 6, and the painted fan-shaped punches fall along the falling path of the guide baffle 4 onto the stacking pallet. At the same time, the PLC controller sends an air supply signal to the pneumatic reversing valve, and air enters the vibrator 2 through the air pipe. The vibrator 2 vibrates according to the set frequency, aligning the painted fan-shaped punches that fall onto the stacking pallet.

[0023] When the fan-shaped punches fall into the stacking pallet, the photoelectric switch 5 automatically tracks the stacking height and sends a signal to control the hydraulic lifting platform to rise and fall, ensuring that the collection height can accurately count the number of fan-shaped punches. When the specified number of stacked pieces is reached, the photoelectric switch will send a signal to stop the collection work and remove the stacked fan-shaped punches from the unloading area and into the hoisting area.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
