Description

Technical Field

[0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to an automatic receiving device for magnetic MIM products after sintering. Background Art

[0002] Metal Injection Molding (MIM) is a new near-net-shape forming technology. It's the product of the interpenetration and intersection of multiple disciplines, including plastic injection molding technology, polymer chemistry, powder metallurgy technology, and metal materials science. It uses molds to injection-mold preforms and then rapidly sinters them to create high-density, high-precision, high-strength, and three-dimensionally complex structural parts. MIM technology can easily produce small parts with complex shapes that are difficult to machine or process using other processes, especially mechanical machining. It offers advantages such as low cost, high efficiency, and good consistency, making it easy to mass-produce and is known as "today's most popular component forming technology." The metal powder injection molding process includes mixing, injection molding, degreasing, and sintering. Currently, structural parts manufactured using the MIM process are small in size and complex in structure. During sintering, to prevent deformation and increase sintering capacity, the injection-molded MIM workpieces need to be placed on a sintering jig for sintering. After sintering, the MIM product needs to be separated from the sintering jig. With existing technology, MIM products are manually separated and processed. This manual operation not only increases the labor intensity and low separation efficiency of workers, but also requires a large number of workers, resulting in high labor costs.

Implementation Method

[0018] The present invention is further described below with reference to the embodiments and accompanying drawings, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0019] like Figures 1 to 5 As shown, the present invention includes a machine base 1 and a conveying mechanism 2 installed on the machine base 1, the conveying mechanism 2 includes a drive assembly 21 and a workpiece conveyor belt 22, the drive assembly 21 is installed on the machine base 1, and the workpiece conveyor belt 22 is installed on the drive assembly 21. The drive assembly 21 adopts the structure used in the prior art, including an active roller, a driven roller and a drive motor for driving the active roller to rotate. The drive motor drives the active roller to rotate, so that the workpiece conveyor belt 22 can move between the conveyor roller and the driven roller. The machine base 1 above the workpiece conveyor belt 22 is sequentially provided with a brush stripping machine The magnetic separation mechanism 4 is arranged upwardly and obliquely above the workpiece conveyor belt 22, and a material guide trough 7 is installed obliquely below the higher end of the magnetic separation machine 4. The discharging direction of the material guide trough 7 is perpendicular to the conveying direction of the workpiece conveyor belt 22, and a product box 8 is provided below the lower end of the material guide trough 7. A ceramic plate receiving trolley 9 is provided on the outside of the machine base 1 corresponding to the ceramic plate stacking mechanism 5, and a graphite plate receiving trolley 10 is provided on the outside of the machine base 1 corresponding to the graphite plate stacking mechanism 6.

[0020] The method of using this device is: when the sintered MIM product needs to be separated from the ceramic plate and the graphite plate, a worker first places the ceramic plate and the graphite plate carrying the MIM product on the conveying mechanism 2, and then turns on the driving component 21. The driving component 21 drives the workpiece conveyor belt 22 to move. During the movement of the workpiece conveyor belt 22, the ceramic plate and the graphite plate carrying the MIM product can be conveyed. When the ceramic plate and the graphite plate carrying the MIM product move to the bottom of the brush separation mechanism 3, the brush separation mechanism 3 can separate the MIM product from the ceramic plate and the graphite plate. The separated MIM product, ceramic plate and graphite plate continue to move. When When moving to the magnetic separation mechanism 4, since the MIM product is made of metal and has magnetism, the magnetic separation mechanism 4 set up during the movement can realize the sorting of MIM products from ceramic plates and graphite plates, and the sorted MIM products are collected through the material guide trough 7 and enter the finished product box 8, and the sorted ceramic plates and graphite plates continue to move along the workpiece conveyor belt 22. During the movement, the ceramic plate stacking mechanism 5 set up can absorb the ceramic plates on the workpiece conveyor belt 22 and stack them neatly in the ceramic plate receiving cart 9, and the graphite plate stacking mechanism 6 set up can absorb the graphite plates on the workpiece conveyor belt 22 and stack them neatly in the graphite plate receiving cart 10. The present invention only requires one person to place the sintered MIM products on the conveying mechanism 1 to achieve the separation and magnetic separation of MIM products and the collection and stacking of graphite plates and ceramic plates. This not only effectively reduces the number of workers and greatly reduces the labor cost, but also greatly reduces the labor intensity of workers. Only one person is required to participate in automatic separation and automatic stacking and collection, which has the advantages of high separation and collection efficiency, strong practicality and high degree of automation.

[0021] Furthermore, the brush removal mechanism 3 includes a first motor 31 and a roller 32. The first motor 31 is an existing technology, and it is only necessary to purchase a finished motor according to usage requirements. Support plates are installed on both sides of the machine base 1, and the roller 32 is rotatably installed between the two support plates. The first motor 31 is installed on one of the support plates and is transmission-connected to one end of the roller 32. Multiple groups of wire brushes 33 are installed on the outer wall of the roller 32. When working, the first motor 31 drives the roller 32 to rotate, and the roller 32 drives the wire brush 33 to rotate during the rotation process. During the rotation process, the wire brush 33 can remove the ceramic plate and graphite plate carrying the MIM product until they are separated.

[0022] Furthermore, the magnetic separation mechanism 4 uses a belt magnetic separator used in the prior art, and the magnetic separation mechanism 4 includes a frame, a magnetic roller 41, a non-magnetic roller 42 and a magnetic separation conveyor belt 43. The magnetic roller 41 adopts the structure used in the prior art, that is, a magnetic material is placed inside the roller shaft so that the magnetic roller has better magnetism. The frame is arranged into an inclined structure, and the frame is mounted on the machine base 1. The magnetic roller 41 is rotatably installed at the lower end of the frame, and the non-magnetic roller 42 is rotatably installed at the higher end of the frame. It is arranged into an inclined structure in order to achieve better magnetic separation effect. The magnetic separation conveyor belt 43 is sleeved between the magnetic roller 41 and the non-magnetic roller 42. A second motor 44 is installed on the frame. The second motor 44 is existing technology and is directly purchased as a finished motor according to usage requirements. The output shaft of the second motor 44 is transmission connected to one end of the non-magnetic roller 42. When the separated MIM products, ceramic plates and graphite plates are magnetically separated, the second motor 44 drives the non-magnetic roller 42 to rotate, and then drives the magnetic conveyor belt 43 and the magnetic roller 41 to rotate. During the rotation of the magnetic roller 41, the magnetic MIM products can be adsorbed on the magnetic conveyor belt 43 at the magnetic roller 41. The magnetic conveyor belt 43 moves with the MIM products. During the movement, as the magnetism disappears, the MIM products on the magnetic conveyor belt 43 fall from one end of the non-magnetic roller 42 and enter the material guide trough 7.

[0023] Furthermore, the ceramic plate stacking mechanism 5 includes a support frame 51 and a vacuum sponge suction cup 52. The vacuum sponge suction cup 52 is a prior art. According to the needs of use, the vacuum sponge suction cup 52 is a pneumatic actuator with a sealing lip. After contacting the sucked object, a temporary sealed space is formed. The air in the sealed space is extracted or thinned to generate a pressure difference between the inside and the outside to work. The vacuum sponge suction cup 52 used in the present invention adopts a rectangular parallelepiped structure. The support frame 51 is erected above the machine base 1. The support frame A horizontal base plate 53 extending to the top of the ceramic plate receiving car 9 is installed on one side of the top of the frame 51. A horizontal slide 54 is installed on the horizontal base plate 53 through a translation component. The moving direction of the translation component is perpendicular to the conveying direction of the workpiece conveyor belt 22. A guide vertical plate 55 is vertically installed on the horizontal slide 54. A lifting slide 56 is installed on the guide vertical plate 55 through a lifting component. The moving direction of the lifting component is perpendicular to the moving direction of the translation component. A horizontal connecting rod 57 is installed on the lifting slide 56. 7 is arranged parallel to the conveying direction of the workpiece conveyor belt 22, and a guide rod 58 is installed at the end of the horizontal connecting rod 57. The vacuum sponge suction cup 52 is installed at the lower end of the guide rod 58. When it is necessary to sort the ceramic plates on the workpiece conveyor belt 22, according to the position of the ceramic plates, the translation component first drives the horizontal slide 54 and the guide vertical plate 55 to translate along the horizontal bottom plate 53. When they are translated to be parallel to the position of the ceramic plates, the lifting component drives the lifting slide 56, the horizontal connecting rod 57, the guide rod 58 and the vacuum sponge suction cup 52 to move downward together. When the vacuum sponge suction cup 52 contacts the ceramic plate, the vacuum sponge suction cup 52 can suck up the ceramic plate, and the translation component then drives the horizontal slide 56 and the guide vertical plate 55 to translate along the horizontal bottom plate 53 toward the ceramic plate receiving trolley 9. When it translates to the top of the ceramic plate receiving trolley 9, the lifting component drives the vacuum sponge suction cup 52 downward to sort out the ceramic plates and stack them in the ceramic plate receiving trolley 9. After that, the ceramic plate stacking mechanism 5 returns to its original position. According to the above-mentioned operating method, the sorting and stacking of ceramic plates can be automatically completed.

[0024] Preferably, the translation assembly includes a translation driving wheel 59, a translation driven wheel 510, a translation conveyor belt 511 and a translation motor 512.

A translation groove is provided on one side of the horizontal bottom plate 53 along the length direction of the horizontal bottom plate 53. The translation driving wheel 59 and the translation driven wheel 510 are symmetrically installed at both ends of the translation groove. The translation conveyor belt 511 is sleeved between the translation driving wheel 59 and the translation driven wheel 510. The translation motor 512 is installed at one end of the horizontal bottom plate 53 and is connected to the translation driving wheel 59.

A first clamping plate 513 is installed on one side of the horizontal slide 54, and the first clamping plate 513 is clamped on the translation conveyor belt 511. During operation, the translation motor 512 drives the translation driving wheel 59 to rotate. During the rotation of the translation driving wheel 59, the translation conveyor belt 511 is driven to move through the translation driven wheel 510. During the movement of the translation conveyor belt 511, since the first clamping plate 513 is clamped on the translation conveyor belt 511, the translation conveyor belt 511 can drive the translation slide 54 to move back and forth on the horizontal base plate 53 along the translation rail.

[0025] Preferably, the lifting assembly includes a lifting driving wheel 514, a lifting driven wheel 515, a lifting conveyor belt 516 and a lifting motor 517. The lifting motor 517 is a prior art and can be directly manufactured as a motor according to the needs of use. A lifting groove is provided on one side of the guide vertical plate 55 along the length direction of the guide vertical plate 55. The lifting driving wheel 514 and the lifting driven wheel 515 are symmetrically installed at both ends of the lifting groove. The lifting conveyor belt 516 is sleeved between the lifting driving wheel 514 and the lifting driven wheel 515.

A second clamping plate is installed on one side of the lifting slide 56, and the second clamping plate is clamped on the lifting conveyor belt 516. During operation, the lifting motor 517 drives the lifting active wheel 514 to rotate. During the rotation of the lifting active wheel 514, it can drive the lifting driven wheel 515 and the lifting conveyor belt 516 to move. During the movement of the lifting conveyor belt 516, since the second clamping plate is clamped on the lifting conveyor belt 516, the lifting conveyor belt 516 can drive the lifting slide 56 to move up and down on the guide vertical plate 55 along the lifting slide rail.

[0026] Furthermore, the structure of the graphite plate stacking mechanism 6 is the same as that of the ceramic plate stacking mechanism 5. The operating principle of the graphite plate stacking mechanism 6 is also the same as that of the ceramic plate stacking mechanism 5 and will not be elaborated here. The purpose of the graphite plate stacking mechanism 6 is to automatically sort the graphite plates from the workpiece conveyor belt 22 and automatically stack them in the graphite plate receiving vehicle 10.

[0027] Furthermore, in order to achieve complete separation of the MIM workpiece from the ceramic plate and the graphite plate and prevent incomplete separation of the brush separation mechanism 3, which affects the subsequent magnetic separation, sorting and stacking assembly line work, a cam separation mechanism is further provided in the machine base 1 below the brush separation mechanism 3. The cam separation mechanism includes a third motor 11 and multiple transmission shafts 12. The third motor 11 is a prior art and is directly purchased as a finished product according to the needs of use. Multiple transmission shafts 12 are installed on the machine base 1 at equal intervals. At least two cams 13 are installed on each transmission shaft 12 at intervals.

During the operation of the workpiece conveyor belt 22, the third motor 11 is turned on, and the third motor 11 drives the transmission shaft 12 connected thereto to rotate. Under the transmission action of the pulley 14 and the transmission belt 15, multiple rotating shafts 12 rotate synchronously, thereby driving multiple cams 13 to rotate. During the transmission process, the cam 13 will contact the upper surface of the workpiece conveyor belt 22, so that the workpiece conveyor belt 22 will continue to fluctuate and vibrate during the operation. The fluctuation and vibration of the workpiece conveyor belt 22 can make the graphite plate and ceramic plate carrying the MIM workpiece flipped, thereby realizing the separation of the MIM workpiece from the graphite plate and ceramic plate. Preferably, the cams 13 on two adjacent transmission shafts 12 are staggered with each other, so that the amplitude of the fluctuation and vibration of the workpiece conveyor belt 22 during operation can be uniform, thereby improving the separation efficiency of the graphite plate and ceramic plate of the MIM workpiece.
