Description

[0002] At present, after sintering, powder metallurgy products are sent to the shaping mold for finishing, and the products are taken out of the shaping mold after the finishing action is completed. For example, for special-shaped products, for example, the annular product used for the rotating seat of the rearview mirror of the car, during processing, several raised structures will be processed on the outer side of the circumference of the annular product. In the actual material process, when each workpiece is placed, the raised structure will have inconsistent placement directions, and the shaping structure is set for the workpieces with the same raised structure orientation. If the placement direction of each workpiece is inconsistent, that is, there will be a situation where the boss faces forward or backward, if it flows directly into the shaping station, it will cause the shaping to be wrong, or it needs to be adjusted manually, resulting in low processing efficiency.

DETAILED DESCRIPTION

[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0030] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] like Figure 1 The automatic workpiece shaping device shown in Figure 6 includes a machine body 10, a vibration plate feeding mechanism 20, a positioning mechanism 30, a shaping mechanism 40 and a transfer mechanism 50, and a feeding station is provided on the machine body 10.

[0033] The specific vibration plate feeding mechanism 20 includes a vibration plate and a vibration plate driving member, on which a vibration cavity 21, a first conveying channel and a second conveying channel 23 are provided, one end of the first conveying channel is connected to the vibration cavity 21, and the other end of the first conveying channel is formed as a discharge end, which connects the discharge end with the feeding station, and the first conveying channel surrounds the outside of the vibration cavity 21.

[0034] The second conveying channel 23 is disposed on the outer periphery of the first conveying channel. The second conveying channel 23 is located below the first conveying channel to receive the workpiece dropped from the first conveying channel.

[0035] The vibration plate driving member can drive the vibration plate to vibrate so as to drive the workpiece to fit the side wall of the first conveying channel for conveying. A screening portion is provided at the bottom end of the first conveying channel, which can contact the bottom end of the workpiece when the workpiece is conveyed so that workpieces with inconsistent placement directions fall into the second conveying channel 23.

[0036] In addition, the positioning mechanism 30 can receive the workpiece from the loading station and position the workpiece, while the shaping mechanism 40 can receive the workpiece positioned by the positioning mechanism 30 and shape the workpiece. The transfer mechanism 50 can take and place the workpiece and can reciprocate between the loading mechanism, the positioning mechanism 30 and the shaping mechanism 40.

[0037] On the basis of the above structure, when using the automatic workpiece shaping equipment of the present invention, taking the workpiece as an annular workpiece as an example, when loading, multiple annular workpieces can be placed in the vibration cavity 21 of the vibration plate, and the vibration plate driving member can drive the vibration plate to vibrate. During the vibration process, the vibration plate can drive the annular workpiece in the vibration cavity 21 to be discharged from the first conveying channel, and the annular workpiece can be attached to the side wall of the first conveying channel for continuous conveying.

[0038] When the annular workpiece is conveyed to the screening part, the bottom end of the annular workpiece can contact the screening part. If the center of gravity of the annular workpiece is unbalanced, the annular workpiece will be offset when contacting the screening part, and fall from the first conveying channel. It will be received by the second conveying channel 23, and the workpieces with inconsistent placement directions will be unloaded through the second conveying channel 23, and the workpieces unloaded to the second conveying channel 23 can continue to return to the vibration plate, and then be loaded through the first conveying channel. In this way, the workpieces exported to the loading station through the discharge end of the first conveying channel are all workpieces with consistent placement directions, that is, the placement directions of the workpieces can be screened before loading, and centralized processing can be carried out, that is, the workpieces entering the positioning mechanism 30 and the shaping mechanism 40 are workpieces with the same placement directions, and are output after shaping, so as to avoid rework and process waste, and the shaping efficiency is higher.

[0039] Specifically, when the annular workpiece is transported to the loading station, the transfer mechanism 50 can clamp the workpiece and transfer it to the positioning mechanism 30 for positioning. After positioning, it is transferred to the shaping mechanism 40 for shaping via the transfer mechanism 50, thereby realizing automatic loading, positioning and shaping, with a high degree of automation and improved shaping efficiency.

[0040] It should be noted that the above-mentioned shaping mechanism 40 can be implemented by a shaping mold structure in the prior art. When the workpiece is annular, the annular workpiece can be mounted on a shaping rod of the shaping mold for shaping. Since the structure and shaping principle of the shaping mechanism 40 are prior art, they do not belong to the technical content to be protected by this application and will not be described in detail here.

[0041] Furthermore, the above-mentioned screening part includes a notch 221 arranged at the bottom end of the first conveying channel. When the annular structure conveys the notch 221, the arc-shaped bottom end of the annular workpiece can be placed in the notch 221. If the directions of the protruding structures on both sides of the notch 221 on the annular workpiece are inconsistent, the center of gravity will be unstable, and it will fall from the first conveying channel to the second conveying channel 23, thereby realizing the screening of the direction of the workpiece.

[0042] More specifically, the screening portion also includes a protruding portion 222 protruding from the bottom end of the first conveying channel, and the protruding portion 222 and the notch 221 are spaced apart on the first conveying channel, that is, the annular workpiece can be screened for the first time at the notch 221, and in the process of continuing to convey in a conveying channel, the annular workpiece can be conveyed to the protruding portion 222, and the bottom end of the arc of the annular workpiece can contact the protruding portion. If the directions of the protruding structures on both sides of the protruding portion on the annular workpiece are inconsistent, the center of gravity will be unstable, and the workpiece will fall from the first conveying channel to the second conveying channel 23, thereby realizing secondary screening of the workpiece and achieving higher screening efficiency.

[0043] Furthermore, a limiting piece 223 may be provided at the top of the first conveying channel, and the limiting piece 223 is spaced apart from the side wall of the first conveying channel. The limiting piece 223 may extend to the discharge end in the conveying direction of the first conveying channel, and the above-mentioned notch 221, protrusion 222 and limiting piece 223 are spaced apart in the conveying direction of the first conveying channel. In this way, the annular workpiece that has been screened twice by the notch 221 and the protrusion 222 may continue to be transported to the discharge end, and under the limiting effect of the limiting piece 223, the annular workpiece may enter the space formed by the limiting piece 223 and the side wall of the first conveying channel to prevent the workpiece from falling after being screened, and the limiting piece 223 may also ensure that only one annular workpiece is discharged each time.

[0044] Furthermore, the positioning mechanism 30 in this embodiment includes a positioning shaft 31, a positioning shaft driving member, a baffle 32 and a baffle driving member 33. The positioning shaft 31 is pivotally connected to the body 10, and the positioning shaft 31 can be used to pass through the annular workpiece. In addition, the positioning shaft driving member can drive the positioning shaft 31 to rotate.

[0045] In addition, the baffle 32 is disposed on the machine body 10 , and the baffle 32 can be located on the rotation track of the positioning shaft 31 . The baffle driving member 33 can drive the baffle 32 to move closer to or away from the positioning shaft 31 .

[0046] During positioning, the transfer mechanism 50 can clamp the annular workpiece and place it on the positioning shaft 31, so that the annular workpiece is mounted on the positioning shaft 31, and then the positioning shaft driving component can drive the positioning shaft 31 to rotate. At the same time, the baffle driving component 33 can drive the baffle 32 to move close to the positioning shaft 31. During the rotation of the positioning shaft 31, the protruding structure outside the annular workpiece can abut against the baffle 32, so that the annular workpiece can be positioned at the position of the baffle 32, so that the positioning angle of the annular workpiece entering the shaping mechanism 40 is the same each time.

[0047] It should be noted that the positioning shaft driving member can be a motor in the prior art, the rotating shaft of the motor can be connected to the positioning shaft 31, the rotating shaft of the motor can drive the positioning shaft 31 to rotate, and the rotation of the positioning shaft 31 can realize the positioning of the annular workpiece.

[0048] Furthermore, the positioning mechanism 30 also includes a workpiece detection member 34, which is arranged on the side of the positioning shaft 31 to detect the positioning state of the workpiece. That is, when the positioning shaft 31 drives the annular workpiece to rotate, when the protruding structure outside the annular workpiece abuts against the baffle 32, the workpiece detection member 34 can detect whether the protruding structure of the annular workpiece is rotated in place, thereby further improving the positioning accuracy. If it is not positioned in place, the positioning shaft driving member can drive the positioning shaft 31 to rotate further, thereby fine-tuning the position of the annular workpiece.

[0049] Of course, two of the above-mentioned workpiece detection parts 34 can be set, and the two workpiece detection parts 34 can be distributed at intervals on the rotation trajectory of the positioning shaft 31. The two workpiece detection parts 34 can respectively correspond to the raised structures set at intervals on the surface of the annular workpiece. The two workpiece detection parts 34 can simultaneously correspond to the two raised structures of the annular workpiece, and the positioning can be more accurate.

[0050] In this embodiment, the workpiece detection member 34 may be a fiber optic sensor in the prior art that can sense the characteristic position of the raised structure of the annular workpiece, identify whether the annular workpiece is positioned in place, and also identify whether there is a workpiece on the sensing positioning shaft 31.

[0051] It should be noted that the workpiece detection member 34 may also be implemented by other detection structures such as a camera or a photoelectric sensor in the prior art.

[0052] Furthermore, a guide portion and a step surface may be provided at the top of the positioning shaft 31, wherein the outer diameter of the guide portion gradually increases from top to bottom, and the step surface may abut against the bottom end surface of the workpiece when the positioning shaft 31 is inserted into the workpiece. In this way, when positioning, the transfer mechanism 50 can fit the annular workpiece onto the top of the positioning shaft 31, and since the outer diameter of the guide portion provided at the top gradually increases from top to bottom, during the process of inserting the annular workpiece, the annular workpiece can be smoothly loaded through the portion with a smaller outer diameter at the top, and during the process of moving downward, since the inner diameter gradually increases, the annular workpiece is tightly fitted with the annular workpiece, thereby preventing the annular workpiece from rotating during the rotation of the positioning shaft 31.

[0053] In addition, since a step surface is also provided at the bottom end of the positioning shaft 31 , the step surface can abut against the bottom end of the annular workpiece to prevent the annular workpiece from falling during the positioning process and affecting the positioning accuracy.

[0054] Furthermore, in this embodiment, the transfer mechanism 50 includes a transfer arm 52, a transfer arm driving component 53 and two clamps 51. The two clamps 51 are spaced apart on the transfer arm 52, and the transfer arm driving component 53 is used to drive the transfer arm 52 to reciprocate between the loading station, the positioning mechanism 30 and the shaping mechanism 40, and the transfer arm driving component 53 is used to drive the transfer arm 52 to move along the height direction of the machine body 10.

[0055] In the initial state, one of the two clamps 51 is located above the loading station, and the other is located at the waiting station. When clamping the workpiece, the transfer arm driving component 53 can drive the transfer arm 52 to move downward, and the clamp 51 above the loading station can clamp the workpiece at the loading station. Thereafter, the transfer arm 52 driving mechanism can drive the transfer arm 52 to move close to the positioning mechanism 30. When the clamp 51 clamping the workpiece corresponds to the top of the positioning mechanism 30, the other clamp 51 can move from the waiting station to the loading station. Thereafter, the transfer arm driving component 53 drives the transfer arm 52 to move downward. During this process, the clamp 51 located above the positioning mechanism 30 can place the workpiece on the positioning mechanism 30, and the clamp 51 located at the loading station can clamp the workpiece at the loading station, that is, the loading station and the positioning mechanism 30 can perform loading and positioning operations at the same time.

[0056] Thereafter, after the workpiece positioning is completed, the transfer arm driving component 53 can drive the transfer arm 52 to continue to move closer to the shaping mechanism 40, and the clamping jaw 51 located at the positioning mechanism 30 can drive the positioned workpiece to continue to move to the shaping station, and the clamping jaw 51 located at the loading station can drive the workpiece at the loading station to move to the positioning mechanism 30, and perform positioning and shaping actions at the same time.

[0057] In this way, the two clamping jaws 51 can perform different processes at two workstations at the same time, thereby improving processing efficiency.

[0058] Of course, the above transfer mechanism can also be directly implemented by a multi-axis robot in the prior art, or by a structure of a vacuum suction cup and a vacuum suction cup driving member, and the specific selection can be made according to actual needs.

[0059] Furthermore, a lifting mechanism 60 may be provided below the loading station, and the lifting mechanism 60 includes a lifting sleeve 61 and a lifting sleeve driving component 62. Specifically, the lifting sleeve 61 may be provided at the loading station, and the lifting sleeve 61 may be connected to the discharge end of the above-mentioned first conveying channel in the initial state, that is, the lifting sleeve 61 is used to receive the workpiece output from the discharge end, and the lifting sleeve driving component 62 is used to drive the lifting sleeve 61 to move along the height direction of the machine body 10.

[0060] When loading the workpiece, the vibration plate vibrates, which can drive the workpiece to be transported to the lifting sleeve 61 through the first conveyor, and then the lifting sleeve driving member 62 moves upward along the height direction of the machine body 10, and the lifting sleeve 61 can cooperate with the clamping claw 51 of the above-mentioned transfer mechanism 50 to load the workpiece.

[0061] Furthermore, a feeding mechanism 70 is also provided on the machine body 10, and the feeding mechanism 70 is used for receiving the workpiece shaped by the shaping mechanism 40 and unloading the workpiece. Specifically, the feeding mechanism 70 includes a feeding claw 71 and a feeding claw driving member 72, and the feeding claw driving member 72 is used to drive the feeding claw 71 to move, that is, after the workpiece completes the shaping action at the shaping mechanism 40, the feeding claw driving member 72 can drive the feeding claw 71 to move to the shaping mechanism 40 to clamp the workpiece. After the feeding claw 71 clamps the workpiece, it can be moved to the unloading station driven by the feeding claw driving member 72 to realize automatic unloading, thereby further improving the degree of automation.

[0062] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
