Description

Technical Field

[0001] This utility model belongs to the technical field of fully automatic punching machines, and in particular relates to a fully automatic punching machine with MIM automatic gate repair capability. Background Technology

[0002] Metal powder injection molding (MIM) is a manufacturing process that combines metal powder metallurgy and plastic injection molding technologies. Its process includes mixing, injection molding, debinding, sintering, and post-processing. After the sintering process, the product parts need to undergo post-processing processes such as surface treatment, heat treatment, and machining to achieve the required appearance and process requirements.

[0003] In the prior art, such as the fully automatic processing device for multiple gate surfaces of MIM products disclosed in Chinese Patent (CN116079056A), there are working platforms and punching dies installed on the working platforms. A punching machine is installed on the working platform above the punching die. A buffer fixture, a positioning fixture, a gate repair machine, and a belt conveyor are arranged sequentially on the discharge side of the punching die. The buffer fixture is fixedly installed on the working platform by a base. A first transfer robot is installed on the working platform above the buffer fixture and the punching die. The positioning fixture is installed on the working platform by a feeding mechanism. The gate repair machine and the belt conveyor are installed on the working platform. A second transfer robot is installed on the working platform above the buffer fixture, the positioning fixture, the gate repair machine, and the belt conveyor.

[0004] This method has the following drawbacks: First, during operation, the main mechanisms of the device are exposed. If foreign objects fall onto these mechanisms unexpectedly, they can easily become stuck or cause misidentification, increasing maintenance costs and potentially leading to accidents. Second, when the feeding mechanism transfers material from the vibrating mechanism to below the punching platform, the material-shifting mechanism needs to move to the central workpiece placement area to move the material to the bottom of the punching machine. The material-shifting mechanisms on both sides also need to slide towards the center above the placement area to transfer the workpieces. The overlapping strokes require one side of the mechanism to slide back before the other side can slide to the middle position, limiting the efficiency of the punching process and resulting in low overall efficiency. Thirdly, in the existing device, punched products are transferred and buffered via a buffer fixture. However, when the transfer robot moves the product onto the buffer fixture, the cutting edge of the punching mechanism faces the opposite direction to the cutting edge of the gate trimming mechanism. Therefore, the punched product needs to be repositioned and the gate requiring repair reversed and aligned with the side of the gate trimming machine in the opposite direction. A mechanism is needed to provide for adjusting the direction of the punched product.

[0005] Therefore, this paper presents a fully automatic punching machine with automatic gate trimming capability for MIM. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] The prior art in this embodiment has the following problems: The inventors have found the following problems in the prior art: 1. When the device is running, the main mechanism of the device is exposed. If an unexpected situation causes a foreign object to fall onto the running mechanism, it is easy for the mechanism to be jammed during operation or to cause the mechanism to misidentify, thereby increasing the maintenance cost of the equipment and causing accidental safety accidents; 2. When the feeding mechanism in the device transfers the material from the vertical vibration mechanism to below the punching platform, the feeding mechanism needs to move to the middle workpiece placement area to feed the material to the bottom of the punching machine. The feeding mechanisms on both sides need to slide towards the middle above the placement area. To transfer the workpiece, the overlapping strokes of the feeding mechanism require one side of the mechanism to slide back before the other side can slide to the middle position, limiting the efficiency of the punching process and resulting in low overall efficiency. Thirdly, in the existing device, the punched products are transferred and buffered through a buffer fixture. However, when the transfer robot moves the product onto the buffer fixture, the cutting edge of the punching mechanism faces the opposite direction to the cutting edge of the gate repair mechanism. Therefore, the punched product needs to be repositioned and the gate that needs repair reversed and aligned with the side of the gate repair machine in the opposite direction. A mechanism is needed to provide for adjusting the direction of the punched product. Example 1

[0034] like Figures 1 to 11 As shown:

[0035] Therefore, the inventor provides a fully automatic punching machine with automatic gate trimming for MIM (Mechanical Injection Molding), including a monitoring device, a transfer buffer device, a vibrating feeder 1, an automatic punching machine 2, a positioning fixture 3, an automatic gate trimming machine 4, and a belt conveyor 5. The monitoring device (not shown in the figure) is respectively installed in the transfer buffer device, the automatic punching machine 2, and the automatic gate trimming machine 4. The vibrating feeder 1 is located on the left side of the inner side of the equipment casing, the automatic punching machine 2 is located on the right side of the vibrating feeder 1, the automatic gate trimming machine 4 is located on the right side of the automatic punching machine 2, the positioning fixture 3 is located on the left side of the automatic gate trimming machine 4, and the belt conveyor 5 is located on the right side of the automatic gate trimming machine 4. The belt conveyor 5 is electrically connected to the control cabinet (not shown in the figure); the transfer buffer device, vibrating feeder 1, automatic punching machine 2, positioning fixture 3, and automatic gate trimming machine 4 are all equipped with equipment shells; the transfer buffer device also includes a feeding robot a6, a feeding robot b7, a distribution mechanism 8, a feeding conveying device 9, and a rotating buffer fixture 10. The feeding robot a6 is located between the vibrating feeder 1 and the automatic punching machine 2, the feeding robot b7 is located between the automatic punching machine 2 and the automatic gate trimming machine 4, the distribution mechanism 8 is located in the middle of the automatic punching machine 2, the feeding conveying device 9 is located on the front and rear sides of the automatic punching machine 2, and the rotating buffer fixture 10 is located between the automatic punching machine 2 and the positioning fixture 3.

[0036] Using the above scheme, the workpiece to be punched is fed into the automatic punching machine 2 from the vibrating feeder 1. After the monitoring device on the loading robot a6 detects the material information, the monitoring device can use a sensor (not shown in the figure) to transmit the image to the control cabinet in real time. The workpiece is moved to the right and above the automatic punching machine 2. After the workpiece to be punched is transferred to the distribution mechanism 8, the distribution mechanism 8 distributes the workpiece to the front and back sides according to the set program. After the monitoring device on the automatic punching machine 2 detects the workpiece signal, the automatic punching machine 2 moves the workpiece to the punching position of the workpiece. The image signal is transmitted to the control cabinet through the monitoring device. The control cabinet controls the automatic punching machine 2 to automatically complete the punching process of the workpiece. The workpiece is pushed outward by the automatic punching machine 2 and falls onto the feeding conveyor 9, entering the waiting area of ​​the gate repair device. The monitoring device above the feeding conveyor 9 detects the workpiece signal, and the control cabinet controls the loading robot b7 to transfer the workpiece to the top of the rotary buffer fixture 10. After the workpiece is repositioned on the rotary buffer fixture 10, the loading robot b7 transfers the workpiece on the rotary buffer device to the positioning fixture 3 through the signal of the monitoring device. After the monitoring device on the automatic gate repair machine 4 detects the workpiece signal, it automatically performs gate repair on the workpiece. After the gate repair is completed, the workpiece is transferred by the loading robot b7 to the belt conveyor 5 and sent out, completing the automatic punching and gate repair of the workpiece. Example 2

[0037] like Figures 1 to 11 As shown:

[0038] Furthermore, a vibration damping pad 11 is also provided below the vibrating feeder 1;

[0039] The vibrating feeder 1 supplies materials to the automatic punching machine 2 through vibration. During operation, a large amount of vibration is generated. This vibration is transmitted to other devices and affects the positioning accuracy and processing precision of the workpiece. The vibration damping pad 11 can be set as a hollow rubber vibration damping pad 11 to buffer the vibration. The vibration damping pad 11 can buffer most of the mechanical vibration and reduce the impact of the operation of the vibrating feeder 1 on the overall operation of the device. Example 3

[0040] like Figures 1 to 11 As shown:

[0041] Furthermore, arc-shaped fixing clips a12 are provided on the front and rear sides above the positioning fixture 3;

[0042] When the workpiece is placed onto the positioning fixture 3 by the loading robot b7, the arc-shaped fixing clamps a12 at both ends of the positioning fixture 3 are squeezed and expanded outward. After the workpiece is placed, the clamps tighten, providing a fixed support for the workpiece and preventing it from shifting due to external vibration during the gate repair process, thus ensuring the processing effect of the device on the workpiece. Example 4

[0043] like Figures 1 to 11 As shown:

[0044] Furthermore, the equipment casing also includes a protective shell 13, a support base 14, an inspection door a15, a feeding hopper 16, an inspection door b17, a waste recycling trough 18, and a waste recycling bin 19. The protective shell 13 is positioned above the support base 14. The inspection door a15 is hinged to the front of the protective shell. The feeding hopper 16 is positioned on the left side of the protective shell. The inspection door b17 is slidably positioned on the front of the support base 14. The waste recycling trough 18 is positioned below the automatic punching machine 2 and the automatic gate repair machine 4, respectively. The waste recycling bin 19 is positioned below the waste recycling trough 18, respectively.

[0045] The protective casing surrounds the main device, preventing external interference during operation, foreign objects from falling into the workpiece during processing, and preventing the device from jamming. This reduces maintenance costs and prevents accidents. Inspection door a15 can be opened to observe the internal operation when needed. Waste recycling tanks 18 are located below the punching and gate repair stations of the automatic punching machine 2 and the automatic gate repair machine 4, respectively. Waste generated during punching and gate repair falls into the waste recycling bin 19 through the waste recycling tank 18. The waste recycling bin 19 can be removed and recycled after opening inspection door b17. Example 5

[0046] like Figures 1 to 11 As shown:

[0047] Furthermore, the loading robot b7 also includes a guide rail bracket 20, a rodless cylinder a21, a support plate 22, a rodless cylinder b23, a sliding cylinder a24, a clamp a25, a clamp b26, a sliding cylinder b27, and a vacuum suction cup 28. The guide rail bracket 20 is respectively set on the front and rear sides of the automatic gate trimming machine 4. The rodless cylinder a21 is set on the guide rail bracket 20. The support plate 22 is set above the slider of the rodless cylinder a21. The rodless cylinder b23 is set on... Above the support plate 22, the slide cylinders a24 are respectively set on the left and right sides of the slider of the rodless cylinder b23. The clamp a25 is set on the left side of the slide cylinder a24 on the left side of the rodless cylinder b23. The clamp b26 is set on the right side of the slide cylinder a24 on the right side of the rodless cylinder b23. The slide cylinders b27 are set in pairs at the front and rear ends of the left side of the clamp a25 and the front and rear ends of the right side of the clamp b26. The vacuum suction cup 28 is set below the slide cylinder.

[0048] Furthermore, the fixture a25 also includes a mounting frame 29, a slide rod 30, a sliding support block 31, and a telescopic cylinder 32. The mounting frame 29 is located on the left side of the slide cylinder a24, the slide rod 30 is located above the mounting frame 29, the sliding support block 31 is slidably located on the front and rear sides of the slide rod 30, and the telescopic cylinder 32 is located on the left side of the mounting frame 29. The output end of the telescopic cylinder 32 is connected to the side of the slide cylinder b27.

[0049] Furthermore, a mounting plate 33 is provided on the right side of the fixture b26, and the slide cylinders b27 are respectively provided on the right side of the mounting plate 33;

[0050] When the punched workpiece enters the gate to be repaired position of the feeding and conveying device 9, the monitoring sensor above the feeding and conveying device 9 detects the workpiece signal and transmits it to the control cabinet. The control cabinet then controls the rodless cylinder a21 to move to the left on the guide rail bracket 20, moving the clamp a25 above the workpiece. Simultaneously, the monitoring sensor on the loading robot b7 controls the rodless cylinder b23 on the support plate 22 to make fine adjustments in the front-back direction. After the clamp a25 is aligned with the workpiece, the control cabinet controls the telescopic cylinder 32 to extend, driving... The sliding support block 31 on the mounting bracket 29 slides on the slide rod 30, so that the slide cylinder b27 and vacuum suction cup 28 on the fixture a25 come above the workpieces at the front and rear ends respectively. Then the slide cylinder a24 and slide cylinder b27 extend downwards, and cooperate with the inner vacuum suction cup 28 to pick up the workpiece. Then, according to the same control method, the telescopic cylinder 32 retracts to pick up the workpieces from the outer vacuum suction cup 28. In this way, the vacuum suction cups 28 at both ends of the fixture a25 simultaneously pick up two sets of workpieces in pairs.

[0051] After the fixture a25 picks up the workpiece from the feeding conveyor 9, the slide cylinder a24 and slide cylinder b27 retract respectively. At the same time, the control cabinet controls the rodless cylinder a21 to move to the right, bringing the workpiece on the fixture a25 to the top of the rotary buffer fixture 10. At this time, the rotary buffer fixture 10 is in the initial position. After the fixture a25 is aligned by the monitoring sensor, it puts the workpiece into the rotary buffer fixture 10, completing the action of the workpiece from the feeding conveyor 9 to the rotary buffer fixture 10.

[0052] After the workpiece is placed on the rotary buffer fixture 10 by the clamp a25, the rotary buffer fixture 10 turns the workpiece so that the cutting edge of the workpiece is aligned with the cutting edge of the automatic gate repair machine. Then, the control cabinet controls the rodless cylinder a21 to move to the right, and controls the clamp a25 to come above the workpiece after it has turned. The workpiece is then picked up and transferred to the positioning fixture 3. After the monitoring sensor on the automatic gate repair machine 4 detects the workpiece signal, it automatically performs gate repair on the workpiece.

[0053] Simultaneously, the rodless cylinder a21 moves back to the left, causing the clamp a25 to return to the gate-to-be-repaired position of the feeding conveyor 9, transferring the workpiece back to the reset rotary buffer fixture 10. The difference is that when the clamp a25 transfers the adjusted workpiece from the rotary buffer device to the positioning fixture 3, the clamp b26 is now positioned above the positioning fixture 3. When the clamp a25 clamps down on the workpiece to be repaired, the right-side sliding cylinder a24 drives the mounting plate 33b down onto the positioning fixture 3, completing the gate repair. Above the finished workpiece, the sliding cylinder c lowers the vacuum suction cup 28 to pick up the repaired workpiece. Then, the rodless cylinder a21 moves to the right. While the fixture a25 places the workpiece with the gate to be repaired above the positioning fixture 3, the fixture b26 is located above the belt conveyor 5. At this time, the fixture b26 puts down the processed workpiece. Fixtures a25 and b26 simultaneously complete the work of transferring the workpiece with the gate repaired and the workpiece without the gate repaired. The device automatically processes the workpiece in this way. Example 6

[0054] like Figures 1 to 11 As shown:

[0055] Furthermore, the distribution mechanism 8 also includes a material base 34, a distribution plate 35, a baffle 36, and a telescopic electric cylinder 37. The material base 34 is located in the middle of the automatic punching machine 2, the distribution plate 35 is located in the middle of the material base 34, the baffle 36 is located on the left and right sides of the distribution plate 35, and the telescopic electric cylinder 37 is located below the distribution plate 35. The output end of the telescopic electric cylinder 37 is hinged to the distribution plate 35.

[0056] In this process, the feeding robot a6 transfers the workpieces from the vibrating feeder 1 to the distribution plate 35 on the material base 34. After the monitoring sensor on the automatic punching machine 2 detects the workpiece signal, it controls the extension of the telescopic electric cylinder 37 under the distribution plate 35 to move the workpieces on the distribution plate 35 to the punching stations on both sides. Each time the distribution plate 35 is lifted, the extension of the telescopic electric cylinder 37 at one end is less than the extension of the other end. In this way, by controlling the extension of the telescopic electric cylinders 37 on both sides through the control cabinet, the distribution plate 35 can be tilted and lifted in different directions, and the workpieces on the distribution plate 35 are distributed to both sides. The baffle 36 prevents the workpieces from falling from the side of the distribution plate 35 during the slippage process. In this way, in the automatic punching machine 2, by setting the distribution mechanism 8 to distribute and divert the workpieces to both sides, the fixed mechanism in the automatic punching machine 2 on both sides can shorten the stroke when moving the workpiece, improve the efficiency of workpiece distribution, and thus improve the work efficiency. Example 7

[0057] like Figures 1 to 11 As shown:

[0058] Furthermore, the feeding and conveying device 9 also includes a collection hopper 38, a drive motor a39, a transmission roller 40, and a conveyor belt 41. The collection hopper 38 is located below the automatic punching machine 2, the drive motor a39 is mounted on the side of the transmission roller 40, and the conveyor belt 41 is mounted on the transmission roller 40.

[0059] After the workpiece is punched on the automatic punching machine 2, it is transferred to the collection hopper 38 and falls from the collection hopper 38 onto the conveyor belt 41. The drive motor a39 drives the transmission roller 40 to rotate, so that the conveyor belt 41 can carry the workpiece to the gate to be repaired. Example 8

[0060] like Figures 1 to 11 As shown:

[0061] Furthermore, the rotating buffer fixture 10 also includes a mounting base 42, a drive motor b43, a rotating platform 44, a buffer fixture 45, and a fixing clamp b46. The mounting base 42 is mounted on the support base 14, the rotating platform 44 is respectively mounted above the mounting base 42, the buffer fixture 45 is respectively mounted above the rotating platform 44, and arc-shaped fixing clamps b46 are respectively provided on both sides of the buffer fixture 45.

[0062] When the loading robot b7 places the workpiece onto the buffer fixture 45, the fixing clamp b46 clamps and fixes the workpiece. After the monitoring sensor on the loading robot b7 detects the signal, the drive motor b43 rotates, rotating the rotating platform 44 180°, so that the direction of the gate to be repaired on the workpiece on the buffer fixture 45 is aligned with the tool side of the automatic gate repair machine 4, which meets the needs of the device to adjust the direction of the workpiece. At the same time, the rotating buffer fixture 10 can work together with the feeding and conveying device 9 and the distribution mechanism 8 to provide buffer workpieces in the overall processing process of the device, thereby improving the continuity of the production process.

[0063] In summary, the device is equipped with an outer casing to prevent external interference during operation, which could lead to errors in workpiece identification or device jamming due to foreign objects falling into the workpiece during processing. This reduces equipment maintenance costs and prevents unexpected safety accidents. A distribution mechanism 8 is installed to distribute and divert workpieces to both sides, allowing the fixed mechanisms in the automatic punching machines 2 on both sides to shorten their travel when moving workpieces, improving workpiece distribution efficiency and thus increasing work efficiency. The device is equipped with a loading robot b7, distribution mechanism 8, feeding and conveying device 9, and rotary buffer fixture 10 to meet the device's need for adjusting workpiece orientation. Simultaneously, the rotary buffer fixture 10, together with the feeding and conveying device 9 and distribution mechanism 8, provides buffering for workpieces in the overall processing flow, improving the continuity of the production process.

[0064] The working principle of this utility model:

[0065] S1. Pour the workpiece from the external feed hopper 16 into the vibrating feed plate 1. The vibrating feed plate 1 supplies material to the automatic punching machine 2 by vibration.

[0066] S2. After the monitoring device on the loading robot a6 detects the material information, it transfers the workpiece to the right onto the distribution mechanism 8.

[0067] S3. After the monitoring sensor on the automatic punching machine 2 detects the workpiece signal, it controls the telescopic electric cylinder 37 under the material distribution plate 35 to extend and move the workpiece on the material distribution plate 35 to the punching stations on both sides respectively.

[0068] S4. The automatic punching machine 2 moves the workpiece to the punching position of the workpiece, and transmits the image signal to the control cabinet through the monitoring device. The control cabinet controls the automatic punching machine 2 to automatically complete the punching process of the workpiece. The workpiece after punching is pushed out by the automatic punching machine 2.

[0069] S5. After punching, the workpiece falls from the collection hopper 38 onto the conveyor belt 41. The drive motor a39 drives the transmission roller 40 to rotate, so that the conveyor belt 41 can carry the workpiece to the gate to be repaired.

[0070] S6. The monitoring sensor above the feeding and conveying device 9 detects the workpiece signal and controls the rodless cylinder a21 to move to the left on the guide rail bracket 20, moving the clamp a25 above the workpiece. At the same time, the monitoring sensor on the loading robot b7 controls the rodless cylinder b23 on the support plate 22 to make fine adjustments in the front and back direction. After the clamp a25 is aligned with the workpiece, the control cabinet controls the telescopic cylinder 32 to extend, driving the sliding support block 31 on the mounting frame 29 to slide on the slide rod 30, so that the slide cylinder b27 and the vacuum suction cup 28 on the clamp a25 come to the workpiece at the front and back ends respectively. Then the slide cylinder a24 and the slide cylinder b27 extend downward, cooperating with the inner vacuum suction cup 28 to pick up the workpiece.

[0071] S7. After the fixture a25 picks up the workpiece from the feeding conveyor 9, the slide cylinder a24 and slide cylinder b27 are retracted respectively. At the same time, the control cabinet controls the rodless cylinder a21 to move to the right, bringing the workpiece on the fixture a25 to the top of the rotary buffer fixture 10.

[0072] S8. The rotary buffer fixture 10 is in the initial position. After the fixture a25 is aligned by the monitoring sensor, it puts the workpiece into the rotary buffer fixture 10, completing the action of the workpiece from the feeding and conveying device 9 to the rotary buffer fixture 10.

[0073] S9. The workpiece is clamped and fixed by the fixing clamp b46. After the monitoring sensor on the loading robot b7 detects the signal, the drive motor b43 rotates and rotates the rotating platform 44 by 180°, so that the direction of the gate to be repaired on the workpiece on the buffer fixture 45 is aligned with the tool side of the automatic gate repair machine 4.

[0074] S10, clamp a25 comes to the workpiece after turning, clamps the workpiece and transfers it to the positioning fixture 3. The arc-shaped fixing clamps a12 at both ends of the positioning fixture 3 are squeezed and expand outward. After the workpiece is put in, it is tightened. The monitoring sensor on the automatic gate repair machine 4 detects the workpiece signal and automatically performs gate repair on the workpiece.

[0075] S11, rodless cylinder a21 moves back to the left, driving fixture a25 back to the gate to be repaired position of feeding and conveying device 9, and transferring the workpiece back to the reset rotary buffer fixture 10.

[0076] S12. When the fixture a25 clamps the workpiece to be repaired, the right slide cylinder a24 drives the mounting plate 33b to descend above the workpiece with the repaired gate on the positioning fixture 3. The slide cylinder c on the fixture b26 lowers the vacuum suction cup 28 to pick up the repaired workpiece.

[0077] S13, the rodless cylinder a21 moves to the right. At the same time as the fixture a25 places the workpiece to be repaired above the positioning fixture 3, the fixture b26 is located above the belt conveyor 5. At this time, the fixture b26 puts down the processed workpiece. The fixtures a25 and b26 simultaneously complete the work of transferring the workpiece with the repaired gate and replenishing the workpiece without the repaired gate. The device automatically processes the workpiece in this way.

[0078] This concludes the description of the working principle of the device.
