[0002] Powder metallurgy is a process technology that uses metal powder (or a mixture of metal powder and non-metal powder) as raw material, and after pressing and sintering, it is made into parts of various shapes. Its process flow generally includes three steps: mixing, pressing and sintering to obtain finished products. After pressing, the pressed blanks need to be arranged on a tray and then sintered. However, most suction mechanisms take out the pressed round rod blanks from the discharge station of the powder forming press in the vertical direction, but the existing blank arrangement machine such as the invention publication number CN115504 241A discloses an automatic blanking and blanking machine suitable for round rod-shaped parts. The blanking and blanking machine is limited to blanking work for round rod-shaped blanks transferred horizontally. If it is docked with blanks transferred vertically, the material collection process between the blanking and blanking machine and the powder molding press lacks continuity and the operation is not flexible enough. Additional manual intervention or a horizontal blank buffer mechanism for connecting to the powder molding press may be required to perform blanking operations on the vertically taken blanks. The time required for switching between workstations is relatively long, which affects the overall work efficiency and greatly increases the production cost. Summary of the invention

The bottom surface of the turntable 51 is transmission-connected with the output portion of the rotary drive device 53 and is driven to rotate by the rotary drive device 53. The turntable 51 is arranged in a cross-shaped structure, and the turning device 52 is provided with four and is horizontally and rotatably arranged at the four corners of the top surface of the turntable 51. The four corners of the top surface of 1 are located below the material turning device 52 and are respectively penetrated with corresponding through holes 511. The flipping and lifting device 55 is installed upward on the rotating material turning support 54 and is located on one side of the rotating driving device 53. The output shaft of the flipping and lifting device 55 extends out of the top surface of the rotating material turning support 54. The rotating driving device 53 can drive the turntable 51 to rotate and make each through hole 511 rotate in turn to above the output shaft of the flipping and lifting device 55. The output shaft of the flipping and lifting device 55 can pass through the corresponding through hole 511 and move upward to lift the material turning device 52 to turn it over, and then move downward to restore the material turning device 52 to a horizontal state.

[0029] Among them, the turntable 51 is designed with a cross-shaped structure so that the turntable 51 has a more uniform weight distribution and stability. The rotation drive device 53 can be set as a common rotation drive motor + shaft assembly on the market.

The bottom of the transfer lifting plate 42 is fixedly arranged on the lifting position of the two transfer lifting drive modules 43 and is transmission-connected to the transfer lifting drive modules 43. The transfer translation drive module 44 is fixedly arranged on the transfer lifting plate 4 2, the bottom ends of the two-way telescopic fork 45 are movably arranged on the translation part of the transfer translation drive module 44 along the direction perpendicular to the transfer translation drive module 44 through the slide rail slider assembly, the transfer lifting drive module 43 can drive the two-way telescopic fork 45 on the transfer translation drive module 44 to move up and down in its vertical direction, the transfer translation drive module 44 can drive the two-way telescopic fork 45 to translate back and forth in its horizontal direction, and the two-way telescopic fork 45 can drive the material tray to extend and retract relative to the transfer translation drive module 44.

[0041] The bidirectional telescopic fork 45 may also be any two-section or three-section bidirectional telescopic fork on the market, which is not limited in this embodiment.

[0042] like Fig.13 and 14 As shown, the press feeding mechanism 6 may include a first X-axis linear module 61, a first Z-axis linear module 62, a feeding bracket 63 and a feeding block 64. The first X-axis linear module 61 is horizontally mounted on a top side of the gantry 11 and is located above the blank discharging station. The first Z-axis linear module 62 is vertically mounted on the output portion of the first X-axis linear module 61. The top of the feeding bracket 63 is connected to the lifting portion of the first Z-axis linear module 62. The feeding block 64 is horizontally mounted on the bottom of the feeding bracket 63 which is tilted outward.

[0043] In specific implementation, the first X-axis linear module 61 and the first Z linear module can drive the material picking block 64 to extend into the discharge station of the external powder molding press to absorb the blank in the vertical direction, and then transfer the absorbed blank to the turning device 52 of the rotary turning mechanism 5 to place it in a horizontal state, and then drive the turntable 51 to rotate to the suction station of the blank discharge suction mechanism 7 through the rotary drive device 53.

[0044] like Fig.15 As shown, the blank discharging and suction mechanism 7 may include a second X-axis linear module 71, a second Z-axis linear module 72, a suction bracket 73, a variable distance module 74 and a suction block 75.

[0045] In specific implementation, when working, the second X-axis linear module 71 and the second Z-axis linear module 72 can drive a number of suction blocks 75 to absorb a number of blanks, and change the distance between the several suction blocks 75 through the variable distance module 74, thereby changing the density of the blank arrangement, and can adapt to the gaps of the positioning grooves 5251 on different positioning fixtures 525, and has a wide range of applications.

[0046] like Figure 3 and Fig.16 As shown, the material tray storage mechanism 2 may include a frame 21, a rotary clamping assembly 22 and a cart guide assembly 23, a plurality of handles 211 are respectively provided on the outer side of the frame 21, a plurality of wheels 212 are provided on the bottom of the frame 21, two rows of storage spaces for storing material trays are longitudinally provided inside the frame 21, support frames 24 are respectively fixed on the two frames inside the frame 21, and a plurality of support blocks 25 horizontally spaced apart for supporting both sides of the material tray are symmetrically provided on the two rows of oppositely arranged support frames 24.

[0047] Specifically, the rotary pressing assembly 22 includes a limit pressing block 221 and a rotary pressing cylinder 222. The rotary pressing cylinders 222 are provided in a plurality and are respectively installed on both sides of the outer side surface where the frame 1 is connected to the vehicle frame 21. During implementation, after the vehicle frame 21 reaches the correct position, the plurality of rotary pressing cylinders 222 drive the corresponding limit pressing blocks 221 to press against the vehicle frame 21, thereby firmly installing the vehicle frame 21 on the frame 1.

[0048] Furthermore, the cart guide assembly 23 includes a guide wheel 231 and a guide wheel mounting seat 232. The guide wheel mounting seats 232 are provided in a plurality and are symmetrically mounted on both sides of the outer side of the frame 1. The guide wheels 231 are provided in a plurality and are rotatably mounted on the inner top of the corresponding guide wheel mounting seats 232.

The cart guide assembly 23 enables the frame 21 to maintain an accurate path during movement, reduce deviation and tilt, and thus improve the accuracy and stability of movement.

[0049] The working principle of this embodiment is as follows:

[0050] like Fig.17 As shown, first, the transfer lifting drive module of the tray transfer mechanism drives the two-way telescopic fork on the transfer translation drive module to extend into the bottom of the empty tray placed in the frame and take out the empty tray, and then the two-way telescopic fork drives the empty tray to move to the top of the pallet ejection device, and the pallet ejection device can drive the lifting plates on both sides to rise to the bottom of the empty tray to lift the empty tray, and then the two-way telescopic fork is reset, and the displacement drive device drives the pallet tightening device to move on the slide rail toward the pallet ejection device. When the two supporting side plates are located on both sides of the empty tray and the side stoppers are in contact with one end of the empty tray, each pallet movable part can lift the bottom of both sides of the empty tray, and the tightening module and the stop module can work together to press the two sides and both ends of the empty tray respectively, and then the empty tray is driven by the displacement drive device to move to the blank discharge station and stop, the first X-axis linear module and the first Z linear module can drive the material taking block to extend into the discharge station of the external powder molding press to absorb the blank in the vertical direction, and then The sucked blank is transferred to the turning device of the rotary turning mechanism. When the turning device docks the blank, the output shaft of the turning and lifting device moves upward to lift the turning block and turn it over. At the same time, the bottom of the blank first contacts the abutment platform, then the output shaft of the turning and lifting device descends, the turning block resets, and the blank falls into the positioning groove under the action of gravity, and then the blank on the turntable is driven by the rotary drive device to rotate to the suction station of the blank discharge suction mechanism. The suction block moves the blank to the blank discharge station driven by the second X-axis linear module and the second Z linear module for blank discharge. After the blank discharge is completed, the pallet displacement mechanism drives the full material tray to move above the pallet ejection device, and the tightening module and the stop module release the abutment against the full material tray. At this time, the transfer lifting drive module and the transfer translation drive module drive the two-way telescopic fork to extend to the bottom of the full material tray again to lift the full material tray upward, and move it to the placement position of the full material tray in the frame, and repeat the above process until the frame is full of full material trays and is manually transferred and transported out.

[0051] To sum up, the present invention can realize a series of automated operations such as automatic supply of empty trays, automatic displacement of trays, automatic taking of blanks, automatic flipping and automatic arrangement of blanks, and automatic storage of full trays through the cooperation between various mechanisms. It is compatible with blanks transferred vertically and blanks transferred laterally, has good adaptability, a high degree of automation, and continuous and smooth operation, which speeds up the unloading rate, improves the overall production efficiency, reduces the need for transportation and production costs, and meets the large-scale production needs of enterprises.

[0052] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
