Description

Technical Field

[0001] This application relates to the technical field of powder forming equipment, and in particular to a servo forming machine for alumina ceramic cleaver powder. Background Technology

[0002] Ceramic cleavers are welding tools used in the wire bonding process of chip packaging. They play an extremely important role in packaging technology and are characterized by high hardness, high mechanical strength, insulation, corrosion resistance, high temperature resistance, high surface finish, high dimensional accuracy, and long service life.

[0003] In related technologies, ceramic cleaver powder forming machines are generally used to process ceramic cleavers. These machines are used to press alumina ceramic powder into specific shapes (such as the sharp ends and complex contours required for ceramic cleavers) to provide high-density and dimensionally accurate blanks for subsequent sintering and processing.

[0004] The ceramic cleaver powder forming machine in the related technology includes an upper punch mechanism, a lower punch mechanism, a master mold, and a powder feeding mechanism. The upper punch mechanism and the lower punch mechanism are located on the upper and lower sides of the master mold, respectively. A forming cavity is opened inside the master mold. The powder feeding mechanism includes a powder distribution box with powder distribution holes on the bottom side. When feeding powder, the powder distribution box moves horizontally so that the powder distribution holes are aligned with the forming cavity. The powder falls into the forming cavity under the action of gravity. Then the powder distribution box moves away, and the upper punch mechanism and the lower punch mechanism simultaneously close the master mold, thereby obtaining the product in the forming cavity.

[0005] However, the friction between alumina ceramic powder particles makes it easy for the powder to form an arch structure in the powder distribution box and at the powder distribution holes, which is called bridging. This hinders the smooth falling of the powder, resulting in uneven powder filling in the molding cavity and easily affecting the processing quality of the product. Summary of the Invention

[0006] In order to ensure that the powder fills the molding cavity and improve the processing quality of the product, this application provides an alumina ceramic cleaver powder servo molding machine.

[0007] This application provides a servo forming machine for alumina ceramic cleaver powder, which adopts the following technical solution: A servo forming machine for alumina ceramic cleaver powder includes a support frame, an upper punch mechanism, a lower punch mechanism, a master mold, and a powder feeding mechanism. The master mold is connected to the support frame, the master mold has a forming cavity, and the upper punch mechanism and the lower punch mechanism are both mounted on the support frame; The powder feeding mechanism includes a powder feeding moving part, a powder distribution box, a connecting frame, and a swing drive source; the powder distribution box has a powder distribution hole on its bottom side, and the powder feeding moving part drives the powder distribution box to move, so that the powder distribution hole communicates with the molding cavity; one end of the connecting frame is hinged to the powder feeding moving part, and the other end of the connecting frame is connected to the powder distribution box, and the swing drive source drives the connecting frame to swing, so that the powder distribution box swings up and down.

[0008] By adopting the above technical solution, the oscillating drive source drives the connecting frame to oscillate, causing the powder distribution box to oscillate up and down continuously during the movement, thereby promoting the powder to fall fully into the molding cavity, making the molding cavity full of powder, effectively avoiding powder loss during the transfer process and resulting in insufficient powder in the molding cavity, thus improving the processing and molding quality of the product.

[0009] Optionally, the powder feeding mechanism further includes a powder feeding pipe, which is connected to the inside of the powder distribution box.

[0010] By adopting the above technical solution, the powder feeding pipe can continuously replenish powder into the powder distribution box, so that the powder distribution box can continuously deliver powder to the molding cavity during movement and shaking, thereby improving the continuity and sufficiency of powder feeding and further improving the filling effect of powder in the molding cavity.

[0011] Optionally, the powder feeding mechanism further includes a powder guiding groove plate, which has powder guiding holes that communicate with the forming cavity, and the powder distribution box slides along the powder guiding groove plate.

[0012] By adopting the above technical solution, the powder guiding trough plate guides the movement of the powder distribution box, so that the powder distribution hole can be accurately aligned with the powder guiding hole and the forming cavity, thereby improving the powder feeding accuracy; at the same time, the powder guiding trough plate can catch the powder spilled from the powder distribution box, which is beneficial for the subsequent collection of excess powder.

[0013] Optionally, the powder distribution box is equipped with a striking mechanism, which strikes the powder guiding groove plate when the powder distribution box swings up and down.

[0014] By adopting the above technical solution, the striking mechanism strikes the powder guide plate to generate vibration, which on the one hand helps the powder in the powder feeding pipe and powder distribution box fall into the molding cavity, and on the other hand helps the powder in the molding cavity to be more densely distributed, effectively reducing the bridging phenomenon of powder in the powder feeding pipe, powder distribution box and molding cavity, and promoting the smooth flow of powder into the molding cavity.

[0015] Optionally, the striking mechanism includes a striking plate, a guide shell, an elastic element, and a locking assembly; the guide shell is connected to the powder box, the striking plate is slidably connected to the guide shell, the elastic element is connected to the guide shell and the striking plate respectively, and the locking assembly is used to lock or unlock the position of the striking plate; When the powder distribution box moves away from the master mold, the locking component locks the position of the striking plate; when the powder distribution box moves away from the master mold by a certain distance, the locking component releases the locking of the striking plate, and the elastic element causes the striking plate to strike the powder guiding groove plate.

[0016] By adopting the above technical solution, the locking component locks and unlocks the striking plate, so that the elastic element pushes the striking plate to strike the powder guide groove plate after the powder distribution box is a certain distance away from the master mold, thereby achieving a fixed-point strike and generating vibration at the appropriate time to promote the dense distribution of powder.

[0017] Optionally, the locking assembly includes an electromagnet and a magnetic block. The electromagnet is connected to the powder box, and the magnetic block is connected to the tapping plate. The electromagnet is used to magnetically attract the magnetic block.

[0018] By adopting the above technical solution, the magnetic attraction between the electromagnet and the attraction block enables reliable locking and rapid unlocking of the striking plate, with fast response speed, precise control, and easy realization of automated striking.

[0019] Optionally, one end of the powder guiding groove plate is connected to a powder collection bin. When the powder distribution box moves along the powder guiding groove plate, the elastic element pushes the striking plate to abut against the powder guiding groove plate. The striking plate moves along the powder guiding groove plate and scrapes excess powder into the powder collection bin.

[0020] By adopting the above technical solution, the tapping plate also has a powder scraping function as it moves with the powder box. It can scrape excess powder from the powder guide plate into the powder collection bin, realize the recycling of powder, reduce powder waste, and at the same time keep the surface of the powder guide plate clean to avoid residual powder affecting subsequent powder feeding operations.

[0021] Optionally, the powder feeding mechanism further includes a blocking component, which includes a blocking drive source and a blocking plate. The blocking drive source is connected to the powder distribution box, and the blocking plate is connected to the blocking drive source. The blocking drive source drives the blocking plate to move, thereby opening and closing the powder distribution hole.

[0022] By adopting the above technical solution, the blocking drive source drives the blocking plate to move to open and close the powder distribution hole. The powder distribution hole can be opened when powder feeding is needed and blocked in time when powder feeding ends. This facilitates the control of powder feeding timing and amount, and avoids continuous powder outflow causing waste or affecting the precise control of powder amount in the molding cavity.

[0023] Optionally, a receiving mechanism is also included, which includes a clamping jaw, a receiving box, a receiving drive source, and a guide channel; the clamping jaw is connected to the bottom side of the master mold and is used to clamp the product; the receiving drive source drives the guide channel to move, so that the guide channel is located below the clamping jaw, and the guide channel guides the product into the receiving box.

[0024] By adopting the above technical solution, the clamping jaws hold the formed product, and the receiving drive source drives the guide channel to move to the bottom of the clamping jaws to receive the product. The guide channel guides the product into the receiving box, realizing the automatic collection of the product.

[0025] Optionally, the clamping jaws include a clamping jaw body, a clamping jaw plate, and a buffer pad; the clamping jaw body is used to drive the clamping jaw plate to clamp the product; the clamping jaw plate has a receiving groove, the buffer pad is connected to the clamping jaw plate, and the buffer pad covers the receiving groove; when the clamping jaw plate clamps the product, the buffer pad deforms into the receiving groove, and the receiving groove is used to accommodate the product.

[0026] By adopting the above technical solution, the buffer pad deforms into the receiving groove during the clamping process. The receiving groove can accommodate the product, effectively buffer the clamping force, protect the product surface, and reduce clamping damage to the product.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. The oscillating drive source drives the powder distribution box to oscillate up and down through the connecting frame, and combined with the powder feeding pipe and powder guiding trough plate, so that the molding cavity is filled with powder, thereby improving the product processing quality; 2. By striking the powder guiding groove plate through the striking mechanism, the bridging phenomenon of powder in the powder feeding pipe, powder distribution box, powder guiding hole and forming cavity is reduced, and the powder is promoted to fall into the forming cavity and be densely distributed. At the same time, the striking plate can scrape the excess powder into the powder collection bin for recycling. 3. By using the clamping jaws and buffer pads of the receiving mechanism, products can be automatically collected, reducing clamping damage and improving production efficiency.

[0030] The following combination Figures 1 to 7 This application will be described in further detail.

[0031] Example 1:

[0032] Embodiment 1 of this application provides an alumina ceramic cleaver powder servo molding machine.

[0033] refer to Figure 1 and Figure 2 A servo molding machine for alumina ceramic cleaver powder includes a support frame 2, an upper punch mechanism 3, a lower punch mechanism 4, a master mold 5, a powder feeding mechanism 6, and a receiving mechanism 8. The master mold 5 is fixedly connected to the support frame 2 and has a molding cavity. The molding cavity is used to accommodate alumina ceramic powder and, after mold closing, forms an alumina ceramic cleaver blank, i.e., the product. The upper punch mechanism 3 and the lower punch mechanism 4 are both mounted on the support frame 2 and are located on the upper and lower sides of the master mold 5, respectively. A protective cover 1 is fixedly connected to the support frame 2, covering the upper punch mechanism 3, the lower punch mechanism 4, the master mold 5, the powder feeding mechanism 6, and the receiving mechanism 8, thereby providing protection.

[0034] refer to Figure 2 and Figure 3 The upper punch mechanism 3 includes an upper linear module 31, an upper punch mounting plate 32, and an upper punch head 33. The upper linear module 31 specifically adopts a ball screw linear module and includes a guide post 311, an upper force plate 312, a servo motor 313, a transmission component 314, a rotating shaft 315, a force-applying shaft 316, an upper plate 317, and a first connecting seat 318. The guide post 311 is fixedly connected to the support frame 2, and the upper force plate 312 is fixedly connected to the top of the guide post 311. The servo motor 313 is mounted on the upper force plate 312, and the rotating shaft 315 is rotatably connected to the upper force plate 312. The transmission component 314 specifically uses a pulley and a belt, and the servo motor 313 drives the rotating shaft 315 to rotate through the transmission component 314. The upper plate 317 is slidably connected to the guide post 311, and the force-applying shaft 316 is fixedly connected to the upper plate 317. When the servo motor 313 drives the rotating shaft 315 to rotate through the transmission component 314, the rotating shaft 315 causes the force-applying shaft 316 to move axially, and the force-applying shaft 316 causes the upper plate 317 to move up or down along the guide post 311.

[0035] refer to Figure 2 and Figure 3 The first connecting seat 318 is fixedly connected to the upper plate 317, the upper punch mounting plate 32 is fixedly connected to the first connecting seat 318, and the upper punch head 33 is fixedly connected to the upper punch mounting plate 32. The upper linear module 31 drives the upper punch head 33 to move downward through the upper punch mounting plate 32, so that the upper punch head 33 is inserted into the forming cavity from the top side of the female mold 5.

[0036] refer to Figure 2 and Figure 3 The lower punch mechanism 4 includes a lower linear module 41, a lower punch mounting plate 42, and a lower punch head 43. The lower linear module 41 is specifically a servo-driven ball screw linear module. The body of the lower linear module 41 is fixedly connected to the support frame 2, the output end of the lower linear module 41 is fixedly connected to the lower punch mounting plate 42, and the lower punch head 43 is fixedly connected to the lower punch mounting plate 42. The lower linear module 41 drives the lower punch head 43 to move upward or downward through the lower punch mounting plate 42, enabling the lower punch head 43 to be inserted into the forming cavity from the bottom side of the female mold 5.

[0037] refer to Figure 2 and Figure 4The powder feeding mechanism 6 includes a powder feeding moving part 61, a powder guiding trough plate 62, a powder distribution box 63, a connecting frame 64, a swing drive source 65, and a powder feeding pipe 66. The powder feeding moving part 61 is specifically a linear module. The body of the powder feeding moving part 61 is fixedly connected to the support frame 2. One end of the connecting frame 64 is hinged to the output end of the powder feeding moving part 61, and the other end of the connecting frame 64 is fixedly connected to the powder distribution box 63. The swing drive source 65 is specifically a cylinder. The body of the swing drive source 65 is hinged to the output end of the powder feeding moving part 61, and the output shaft of the swing drive source 65 is hinged to the connecting frame 64. When the swing drive source 65 drives the connecting frame 64 to swing up and down, the connecting frame 64 causes the powder distribution box 63 to produce a reciprocating shaking motion.

[0038] refer to Figure 2 and Figure 4 The powder guiding trough plate 62 is fixedly connected to the top side of the female mold 5. The powder guiding trough plate 62 has powder guiding holes that communicate with the molding cavity of the female mold 5. The powder distribution box 63 is a hollow rectangular box with powder distribution holes on its bottom wall that communicate with the powder guiding holes. The powder guiding trough plate 62 is provided with a sliding channel. The bottom wall of the powder distribution box 63 slides in contact with the inner bottom wall of the sliding channel of the powder guiding trough plate 62. The powder feeding moving part 61 drives the powder distribution box 63 to slide back and forth along the upper surface of the powder guiding trough plate 62, so that the powder distribution holes communicate with or are separated from the powder guiding holes. The powder guiding trough plate 62 can guide the movement path of the powder distribution box 63, ensuring the coaxiality of the powder distribution holes, powder guiding holes, and molding cavity, and improving the accuracy of the powder feeding position. On the other hand, the sliding channel of the powder guiding trough plate 62 can catch excess powder that falls from the powder distribution holes during the powder distribution process, preventing powder from scattering to other parts of the equipment and causing pollution and waste.

[0039] refer to Figure 2 and Figure 4 When the oscillating drive source 65 causes the powder distribution box 63 to oscillate up and down via the connecting frame 64, it can promote the continuous downward flow of powder and replenish the molding cavity, thereby improving the sufficiency of powder filling in the molding cavity. In this application, the amplitude of the up-and-down oscillation of the powder distribution box 63 is small, specifically, the vertical distance is less than 10 mm. The powder distribution box 63 oscillates up and down within the sliding channel of the powder guiding plate 62, so that the excess powder spilled from the powder distribution box 63 falls into the sliding channel of the powder guiding plate 62.

[0040] refer to Figure 2 and Figure 4 The bottom end of the powder feeding pipe 66 is connected to the internal cavity of the powder distribution box 63, and the internal cavity of the powder distribution box 63 is connected to the powder distribution hole. The top end of the powder feeding pipe 66 can be connected to an external powder storage tank to continuously supply alumina ceramic powder into the powder distribution box 63, so that the powder distribution box 63 always maintains a sufficient powder reserve, avoids powder feeding interruption, and improves the continuous production capacity of the equipment.

[0041] refer to Figure 2 and Figure 4 A powder collecting bin 67 is fixedly connected to one end of the powder guiding trough plate 62. The upper edge of the opening at the top of the powder collecting bin 67 is flush with the upper surface of the powder guiding trough plate 62. When the powder dispensing box 63 moves along the powder guiding trough plate 62 toward the powder collecting bin 67, the powder dispensing box 63 scrapes the excess powder scattered on the powder guiding trough plate 62 into the powder collecting bin 67, realizing the automatic recycling and reuse of the scattered powder.

[0042] refer to Figure 2 and Figure 5 The receiving mechanism 8 includes a clamping jaw 81, a receiving box 84, a receiving drive source 83, and a guide channel 82. The clamping jaw 81 is fixedly connected to the lower surface of the female mold 5. The upper punching mechanism 3 pushes the product downward from the molding cavity, and the clamping jaw 81 is used to hold the product pushed out of the molding cavity. The receiving drive source 83 is specifically a cylinder. The body of the receiving drive source 83 is fixedly connected to the support frame 2, and the output end of the receiving drive source 83 is fixedly connected to the guide channel 82. The receiving box 84 is fixedly connected to the support frame 2, and the guide channel 82 is inclined, facing the receiving box 84. After the product is ejected, the clamping jaws 81 hold the product, and the receiving drive source 83 drives the guide channel 82 to move below the clamping jaws 81. The clamping jaws 81 release the product, and the product falls into the guide channel 82 and slides into the receiving box 84 along the inclined channel, realizing automatic collection of the product and improving the degree of production automation and production efficiency.

[0043] refer to Figure 5 and Figure 6 Specifically, the clamping jaws 81 include a jaw body 811, two jaw plates 812, and two buffer pads 813. The jaw body 811 is fixedly connected to the lower surface of the female mold 5. The two jaw plates 812 are connected to the jaw body 811, and the jaw body 811 drives the two jaw plates 812 to open and close synchronously in the horizontal direction. The buffer pads 813 are specifically silicone pads, and are fixedly connected to the jaw plates 812, with one-to-one correspondence between the two jaw plates 812 and the two buffer pads 813. Each jaw plate 812 has a receiving groove 8121 on its clamping surface, and the buffer pads 813 cover the receiving grooves 8121 and the clamping surfaces of the jaw plates 812. When the gripper body 811 drives the two gripper plates 812 to clamp the product, the buffer pad 813 undergoes elastic deformation under the pressure of the product, accommodating part of the product's outline within the receiving groove 8121, reducing clamping damage to the product and improving the product's pass rate.

[0044] The implementation principle of the alumina ceramic cleaver powder servo molding machine in Embodiment 1 of this application is as follows: First, the lower punch head 43 of the lower punch mechanism 4 moves to the bottom side of the molding cavity. The powder feeding moving part 61 drives the powder distribution box 63 to move along the powder guiding groove plate 62 to directly above the powder guiding hole, so that the powder distribution hole, the powder guiding hole, and the molding cavity are connected. The powder feeding pipe 66 conveys alumina ceramic powder into the powder distribution box 63. At the same time, the swing drive source 65 drives the connecting frame 64 to swing up and down, so that the powder distribution box 63 swings up and down. Under the action of gravity and shaking, the powder falls into the molding cavity through the powder distribution hole and the powder guiding hole. When the molding cavity is filled with powder, the powder feeding moving part 61 drives the powder distribution box 63 away from the master mold 5 to avoid displacement. Subsequently, the upper punch mechanism 3 and the lower punch mechanism 4 simultaneously close with the female mold 5. After molding is completed, the lower punch head 43 moves downward, and the upper punch mechanism 3 moves downward to eject the molded product from the molding cavity. The clamping jaws 81 hold the product, and the receiving drive source 83 drives the guide channel 82 to move directly below the clamping jaws 81. Then, the clamping jaws 81 release the product, and the product falls into the guide channel 82. The product slides along the channel into the receiving box 84 for collection.

[0045] Example 2:

[0046] Embodiment 2 of this application provides an alumina ceramic cleaver powder servo forming machine. The difference between Embodiment 2 and Embodiment 1 is that: refer to Figure 7 A striking mechanism 7 is provided on one side of the powder distribution box 63. The striking mechanism 7 includes a striking plate 71, a guide shell 72, an elastic element 73, and a locking assembly 74. The guide shell 72 is fixedly connected to the powder distribution box 63, and the striking plate 71 is slidably connected to the guide shell 72. The elastic element 73 is specifically a spring, which is fixedly connected to both the guide shell 72 and the striking plate 71. The elastic element 73 pushes the striking plate 71 to abut against the powder guiding groove plate 62.

[0047] refer to Figure 7 The locking assembly 74 includes an electromagnet 741 and a suction block 742. The electromagnet 741 is fixedly connected to the side wall of the powder distribution box 63, and the suction block 742 is an iron block structure, which is fixedly connected to the striking plate 71. When the powder distribution box 63 moves upward, the electromagnet 741 is energized to generate magnetic force, attracting the suction block 742 and locking the position of the striking plate 71. The elastic element 73 is in a compressed state, and the striking plate 71 moves upward synchronously with the powder distribution box 63. When the powder distribution box 63 moves upward to the predetermined position, the electromagnet 741 is de-energized, the magnetic force disappears, the elastic element 73 releases its elastic force, and the elastic element 73 pushes the striking plate 71 downward to strike the powder guide plate 62. When the powder box 63 moves downward, the elastic element 73 is gradually compressed. When the electromagnet 741 and the suction block 742 are in opposite positions, the electromagnet 741 attracts the suction block 742 to facilitate the next tap of the striking plate 71.

[0048] refer to Figure 7 The vibration generated by the striking plate 71 can be transmitted to the powder distribution box 63, the powder feeding pipe 66 and the molding cavity, promoting the flow of powder in the powder distribution box 63 and the powder feeding pipe 66, making the powder distribution in the molding cavity more compact, effectively reducing the bridging phenomenon of powder in the powder distribution box 63, the powder feeding pipe 66 and the molding cavity, improving the sufficiency of powder filling in the molding cavity, and further improving the molding quality of the product.

[0049] refer to Figure 7 The powder feeding mechanism 6 also includes a sealing component 68, which comprises a sealing drive source 681 and a sealing plate 682. The sealing drive source 681 is specifically an electric cylinder, and its body is fixedly connected to the side wall of the powder distribution box 63. The output end of the sealing drive source 681 is fixedly connected to the sealing plate 682. The sealing plate 682 is slidably connected to the powder distribution box 63. The sealing drive source 681 drives the sealing plate 682 to move horizontally, thereby opening or closing the powder distribution holes. After powder distribution is completed, the sealing drive source 681 drives the sealing plate 682 to close the powder distribution holes, cutting off the powder supply and preventing powder from continuing to spill and causing waste. At the same time, sealing the powder distribution holes during the movement of the powder distribution box 63 can prevent powder from falling from the powder distribution holes into non-forming areas, keeping the equipment clean.

[0050] refer to Figure 7 When the powder distribution box 63 moves along the powder guiding trough plate 62 toward the powder collection bin 67, the bottom end of the striking plate 71 abuts against the inner bottom wall of the sliding channel of the powder guiding trough plate 62. As the powder distribution box 63 moves, the striking plate 71 can scrape the excess powder scattered on the powder guiding trough plate 62 into the powder collection bin 67, realizing the automatic recycling and reuse of scattered powder, effectively reducing the waste of raw materials.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
