The tray discharging mechanism 6 is located on the other side below the discharging station of the material suction and tray placing mechanism 4. A tray sliding track 8 located below the discharging station of the material suction and tray placing mechanism 4 is connected between the tray loading mechanism 5 and the tray discharging mechanism 6. The tray pushing mechanism 7 is located on the side of the tray loading mechanism 5, the tray discharging mechanism 6, and the tray sliding track 8.

[0048] As Figure 14 shown, the material suction and tray placing mechanism 4 may include a material suction and tray placing support 41, a third translation module 42, a third lifting module 43, and a third suction nozzle 44. The third translation module 42 is horizontally mounted on the material suction and tray placing support 41. The third lifting module 43 is longitudinally arranged and is connected to the translation part of the third translation module 42. The third suction nozzle 44 is longitudinally arranged downward and is connected to the lifting part of the third lifting module 43.

[0049] As Figure 15 、 Figure 16 and Figure 17As shown in the figure, the tray unloading mechanism 6 and the tray loading mechanism 5 can both include a tray lifting and conveying module 51 and a lower rotating roller rotating drive device 52. There are two tray lifting and conveying modules 51, which are arranged symmetrically left and right. The tray lifting and conveying module 51 includes side plates 511, upper rollers 512, lower rotating rollers 513, chains 514, and a material supporting member 515 with an L-shaped cross-section. There are two side plates 511, which are arranged longitudinally and at intervals. The upper rollers 512 are horizontally connected between the upper ends of the two side plates 511. The lower rotating rollers 513 are horizontally and rotatably connected between the lower ends of the two side plates 511. Upper gears 516 are rotatably arranged on the upper rollers 512, and lower gears 517 are arranged on the lower rotating rollers 513. The upper gears 516 and the lower gears 517 are synchronously connected through longitudinal chains 514. A number of material supporting members 515 are horizontally connected to the outside of the chains 514, and the material supporting members 515 are arranged at intervals along the chains 514. The lower rotating roller rotating drive device 52 is in transmission connection with the lower rotating rollers 513 of the two tray lifting and conveying modules 51.

[0050] Among them, as Figure 15 shown, in this embodiment, the lower rotating roller rotating drive device 52 can be composed of a motor + bevel gear + rotating shaft. However, this embodiment does not involve improvements in this aspect and will not be elaborated here.

[0051] As Figure 18 shown, the tray pushing mechanism 7 can include a fourth translation module 71, a transverse moving frame 72, a second lifting cylinder 73, and a pushing block 74. The fourth translation module 71 is arranged horizontally.

The second lifting cylinder 73 is installed downward at the other end of the transverse moving frame 72. The pushing block 74 is horizontally installed on the output shaft of the second lifting cylinder 73.

[0052] During operation, the blank feeding and transferring mechanism takes out the blank from the powder molding press and sequentially transfers the blank to the weighing station and the loading station of the blank transfer mechanism. During this process, the weighing mechanism weighs the blank. The rotary cylinder drives the suction hood to rotate 90 degrees upward, and the first lifting cylinder drives the magnet to rise, making the magnet approach the suction hood. At this time, since the magnet is close to the blank, the blank will be attracted by the magnet and fixed on the suction hood. Then the rotary cylinder drives the suction hood to rotate 90 degrees downward, and the second lifting module drives the suction hood to descend above the loading station of the blank feeding and transferring mechanism. The first lifting cylinder drives the magnet to rise and move away from the suction hood. Due to the separation of the magnet, the blank will fall onto the blank positioning fixture. The blank feeding and transferring mechanism drives the blank to move sequentially to the top surface brush, side surface brush, and CCD vision inspection station. At the same time, the fixture rotation driving device drives the blank to rotate. The top surface brush removes the burrs on the top surface of the blank, and the side surface brush removes the burrs on the side surface of the blank. The CCD vision inspection mechanism detects whether there are appearance defects on the blank. Then the suction and tray loading mechanism sucks away the blank and places it on the loading tray. When the tray is full, the tray loading mechanism will convey an empty tray upward. Then the tray pushing mechanism pushes the empty tray to the position below the unloading station of the suction and tray loading mechanism, and at the same time pushes the full tray onto the tray unloading mechanism. The tray unloading mechanism conveys the full tray downward to realize tray unloading.

[0053] In summary, the structure of the present invention is simple, novel, and reasonably designed. It is provided with a blank feeding and transferring mechanism, a weighing mechanism, a blank transfer mechanism, a blank feeding and transferring mechanism, a deburring mechanism, a CCD vision inspection mechanism, a suction and tray loading mechanism, a tray loading mechanism, a tray unloading mechanism, and a tray pushing mechanism. Among them, the blank feeding and transferring mechanism can realize automatic blank feeding and automatic transfer operations. The weighing mechanism can realize automatic weighing operations of the blank. The blank feeding and transferring mechanism can realize automatic conversion of the blank between workstations. The deburring mechanism can realize automatic deburring operations. The CCD vision inspection mechanism can realize automatic appearance inspection operations of the blank. The suction and tray loading mechanism can realize automatic loading and tray loading of the blank. The tray loading mechanism can realize automatic tray loading operations.
