Description

Technical Field

[0001] This utility model relates to the field of powder forming technology, and in particular to a fully automatic compression powder forming machine. Background Technology

[0002] Tantalum (Ta) is a metal with excellent mechanical and physical properties, such as high melting point, excellent ductility, and excellent corrosion resistance. It is widely used in various fields across industries including electrical, electronic, mechanical, chemical, aerospace, and defense. Because tantalum can form a stable anodic oxide film, it has been widely used as the anode material in small capacitors. Recently, with the rapid development of the information technology (IT) industry (such as ICT and electronic technology), the use of tantalum has increased year by year. Tantalum capacitors are used in passive component-intensive products such as TVs, smartphones, laptops, tablet PCs, and automotive electronic components. The tantalum core of these capacitors needs to be pressed from carbon powder into a specific size for subsequent production. This pressing process requires the use of a powder molding machine.

[0003] Most existing powder molding machines are operated by manual filling and pressing. This method is not only inefficient, but also carries the risk that small amounts of carbon powder can cause harm to the human body over time. Utility Model Content

[0004] In order to improve the existing powder molding machines mentioned above, most of them are operated by manual filling and pressing. The manual filling and pressing method not only has low work efficiency, but also a small amount of carbon powder may cause certain harm to the human body over a long period of time.

[0005] This utility model provides a fully automatic compression powder forming machine, which adopts the following technical solution:

[0006] A fully automatic compression powder forming machine includes a toner recovery structure, wherein a compression forming structure is fixedly connected inside the toner recovery structure.

[0007] The toner recycling structure includes a hollow frame with a cavity box fixedly connected to the lower part of the frame. A toner placement box is fixedly connected inside the cavity box, and the toner placement box has through-holes on both sides to facilitate the through-hole installation of pressed and molded structural components.

[0008] Both the toner placement box and the cavity box are connected by an injection hole for easy toner injection, and the injection hole is connected by a matching plug. A photoelectric sensor for detecting toner height is fixedly connected inside the toner placement box.

[0009] The above technical solution uses a photoelectric sensor to continuously monitor the toner level inside the toner storage box. This not only prevents the toner storage box from being empty, but also avoids the second powder conveying pump from operating without load.

[0010] Optionally, a protective door is rotatably connected above the surface of the frame via a hinge, and a limit baffle is fixedly connected below the surface of the frame. A first powder conveying pump is fixedly connected to one side of the outer wall of the frame, and a first powder suction pipe is installed above the first powder conveying pump. One end of the first powder suction pipe extends through the outer wall of the frame and into the interior of the frame. A first powder discharge pipe is installed below the first powder conveying pump, and one end of the first powder discharge pipe extends through the cavity box and into the interior of the toner placement box.

[0011] The above technical solution isolates the toner from the cavity box by setting up a toner placement box, which avoids the situation where the toner is not only prone to adhering to the rotating components of the components when it comes into contact with the components installed inside the cavity box, but also prone to causing motion interference or obstruction to the operation of the components.

[0012] Optionally, the above-mentioned pressing and forming structure includes a powder pressing component that drives and adjusts the powder turning component, and the powder pressing component includes a through-hole plate that penetrates the output end of the pressing cylinder. The through-hole plate is fixedly connected to both sides of the sliding block, and the sliding block slides with the connecting block through the guide sliding groove. The connecting block is fixedly connected to the inner wall of the machine frame.

[0013] Through the above technical solution, the through-hole plate not only serves as a through-fixed connection, but also plays a role in synchronously adjusting the sliding block by applying force. By adjusting the sliding block by applying force, the guide rod can also achieve the same synchronous force adjustment effect of one leading two.

[0014] Optionally, the aforementioned pressing cylinder is fixedly installed inside the upper part of the machine frame via a fixed connecting plate, and an upper pressing mold is fixedly connected to the output end of the pressing cylinder. A lower pressing mold is provided directly below the upper pressing mold, and a conveying hole is provided through the front of the lower pressing mold to facilitate the installation and connection with the powder turning component parts. The lower pressing mold slides on the base via a guide groove, and the base is fixed inside the lower part of the machine frame via a fixing nut.

[0015] Through the above technical solution, the guide groove not only guides and adjusts the sliding of the lower die, but also facilitates the adjustment of the sliding distance between the front and rear of the lower die under force. At the same time, changing the sliding distance of the lower die makes it easier to slide the lower die filled with carbon powder directly below the upper die for pressing.

[0016] Optionally, the rear side of the aforementioned lower die is fixedly connected to the output end of the electric telescopic rod, and the electric telescopic rod is fixedly connected to the rear side inside the frame body. A scraper for leveling the surface above the lower die is fixedly connected between the connecting blocks.

[0017] The above technical solution uses a scraper to level the filled toner, preventing the toner from protruding. Otherwise, the pressed tantalum core will be uneven and may even become unusable.

[0018] Optionally, a guide rod extending into the cavity box is fixedly connected directly below the aforementioned sliding block, and both the cavity box and the frame body are provided with sliding holes to facilitate the sliding adjustment of the guide rod.

[0019] Through the above technical solution, the guide rod is used to compress the rack under downward force. When the rack is compressed, it drives the wire rope to be tightened. When the wire rope is tightened, the spike inserted into the toner is pulled out and the toner is turned over.

[0020] Optionally, the powder-turning assembly includes an L-plate with a sliding groove on its inner side, and the sliding groove is slidably arranged through a sliding strip and a rack. A compression spring is fixedly connected directly below the sliding strip, and the lower part of the compression spring is fixedly connected to the bottom of the sliding groove. The L-plate is fixedly arranged inside the cavity box.

[0021] The above technical solution utilizes a compression spring for elastic recovery, which allows the rack to move in the opposite direction after the guide rod and rack are separated by force. At this time, the wire rope is in a released state, making it easy for the spike to re-insert into the carbon powder for reciprocating powder turning.

[0022] Optionally, the L-plates are fixedly connected by a first connecting shaft with a first gear through a bearing seat, and the first gear meshes with a second gear. The second gear is also provided with a second connecting shaft that matches the bearing seat. A steel wire rope is fixedly connected to one side of the second connecting shaft. One end of the steel wire rope passes through a connecting hole and is fixedly connected to another side of the second connecting shaft. A spike for inserting and turning carbon powder is fixedly connected to the lower middle part of the steel wire rope.

[0023] The above technical solution allows the spiked cones to insert and remove clumps of toner, and also facilitates the simultaneous upward movement of toner from the lower middle to the upper part of the cones when they are pulled up.

[0024] Optionally, both ends of the wire rope are provided with branch suction pipes extending into the toner placement box, and one end of the branch suction pipe is fixedly connected to one end of the second powder conveying pump. A second powder outlet pipe is installed and connected above the second powder conveying pump, and the second powder outlet pipe extends through the limiting baffle and into the machine frame body and is connected to the conveying hole.

[0025] The above technical solution not only facilitates the conveying of toner by connecting the second powder outlet pipe to the conveying hole, but also avoids the fixed connection between the second powder outlet pipe and the lower die, which would result in a distance difference between the upper and lower dies, making it impossible to press and shape the toner.

[0026] In summary, this utility model has at least one of the following beneficial effects: when the second powder conveying pump is running, the toner is conveyed into the lower mold through the second powder outlet pipe. When the toner is conveyed into the lower mold, the photoelectric sensor detects that a certain amount of toner has been extracted and transmits the signal to the controller. At this time, the controller stops the second powder conveying pump from running. Then, the lower mold is moved directly below the upper mold by the electric telescopic rod for pressing and forming.

[0027] During operation, the first powder conveying pump transports the diffused toner powder during the conveying or paving process through the first powder suction pipe to the toner powder placement box for recycling. This not only prevents toner powder loss and waste, but also avoids toner powder adhering to the internal components of the frame body, which would not only affect the appearance of the internal components of the frame body, but also easily diffuse to the outside of the frame body through the limiting baffle.

[0028] The carbon powder spread on the lower die is leveled by scraping with a scraper. This not only avoids the waste of excess carbon powder during pressing, but also compensates for defects in the pressed tantalum core caused by incomplete filling of the lower die during the filling process.

[0029] By using a compression spring, rack, first gear, second gear, first connecting shaft, second connecting shaft, wire rope, and spike, not only can the toner placed inside the toner storage box for a long time not clump together, but it can also remove clumps and turn the toner inside the storage box during the toner pressing process.

[0030] By using an electric telescopic rod to drive the lower die to reciprocate back and forth, it is not only convenient to displace and level the toner conveyed inside the lower die, but also convenient to drive the lower die and the powder outlet pipe to displace and separate under force, thereby achieving an indirect automatic feeding and pressing effect.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0042] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a fully automatic pressing powder forming machine, including a toner recovery structure 1, and a pressing forming structure 2 is fixedly connected inside the toner recovery structure 1.

[0043] The toner recycling structure 1 includes a frame body 101 with a hollow internal structure, and a cavity box 102 is fixedly connected to the lower part of the frame body 101. A toner placement box 103 is fixedly connected inside the cavity box 102, and the toner placement box 103 has through-holes 104 on both sides for easy pressing and molding of the components of the structure 2.

[0044] Both the toner storage box 103 and the cavity box 102 are provided with injection holes 105 for easy toner injection, and the injection holes 105 are connected by matching plugs. A photoelectric sensor for detecting toner height is fixedly connected inside the toner storage box 103.

[0045] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 A protective door 106 is rotatably connected to the upper surface of the frame body 101 via a hinge, and a limit baffle 107 is fixedly connected to the lower surface of the frame body 101. A first powder conveying pump 108 is fixedly connected to one side of the outer wall of the frame body 101, and a first powder suction pipe 109 is installed above the first powder conveying pump 108. One end of the first powder suction pipe 109 penetrates the outer wall of the frame body 101 and extends into the interior of the frame body 101. A first powder outlet pipe 1010 is installed and connected below the first powder conveying pump 108, and one end of the first powder outlet pipe 1010 penetrates the cavity box 102 and extends into the interior of the toner placement box 103.

[0046] There is a placement cavity between the frame body 101 and the cavity box 102. Tools, small daily necessities, or tantalum capacitor cores that have been pressed and formed can be placed in the placement cavity through the material tray. This not only avoids the random placement of tools or daily necessities, but also makes it convenient for subsequent use and retrieval.

[0047] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The pressing and forming structure 2 includes a powder pressing component 201 that drives and adjusts the powder turning component 202. The powder pressing component 201 includes a through-hole plate 2011 that penetrates the output end of the pressing cylinder 2012. The through-hole plate 2011 is fixedly connected to both sides of the through-hole plate 2011 and the driving sliding block 2013 slides with the connecting block 2014 through the guide sliding groove 2015. The connecting block 2014 is fixedly connected to the inner wall of the frame body 101.

[0048] The connecting block 2014 consists of four blocks, and a displacement detection module is installed between the intersecting connecting blocks 2014. The displacement detection module is used to detect the sliding displacement of the pressing mold 2018. By detecting the sliding displacement of the pressing mold 2018, the pressing cylinder 2012 can effectively control the pressing of the toner.

[0049] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The pressing cylinder 2012 is fixedly installed inside the upper part of the frame 101 via the fixed connecting plate 2016, and the output end of the pressing cylinder 2012 is fixedly connected to the upper pressing mold 2017. The lower pressing mold 2018 is provided directly below the upper pressing mold 2017, and the lower pressing mold 2018 has a through-hole 2019 for easy installation and connection with the powder turning component 202. The lower pressing mold 2018 slides with the base 20111 via the guide groove 20110, and the base 20111 is fixed inside the lower part of the frame 101 by the fixing nut.

[0050] Among them, the pressing die 2018 is set up with an internally driven ejection component. When the pressing die 2018 with ejection component is set up, it can not only avoid manual ejection, but also effectively improve the ejection efficiency and speed of the overall pressing and forming.

[0051] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The rear side of the lower pressing mold 2018 is fixedly connected to the output end of the electric telescopic rod 20112, and the electric telescopic rod 20112 is fixedly connected to the rear side of the inside of the frame body 101. A scraper 20113 for scraping the surface of the lower pressing mold 2018 is fixedly connected between the connecting blocks 2014.

[0052] In this process, the electric telescopic rod 20112 moves the lower pressing mold 2018 back and forth for a certain period of time after the toner is conveyed. When the electric telescopic rod 20112 moves the lower pressing mold 2018 back and forth, it not only spreads the toner conveyed inside the lower pressing mold 2018 by pushing force, but also avoids the accumulation of toner after conveying. At the same time, the conveying hole 2019 is opened at one-third of the position of the lower pressing mold 2018. This not only avoids a large amount of toner scattering during the conveying process, but also effectively maintains a certain pressing space below the lower pressing mold 2018 to complete the pressing of the tantalum capacitor core.

[0053] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The guide rod 20114, which extends into the cavity box 102, is fixedly connected directly below the sliding block 2013. Both the cavity box 102 and the frame body 101 are provided with sliding holes to facilitate the sliding adjustment of the guide rod 20114.

[0054] Among them, the guide rods 20114 are set in the same number. When the guide rods 20114 are set in the same number, it is convenient to achieve synchronous force compression and sliding adjustment of multiple racks 2024.

[0055] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The powder-turning assembly 202 includes an L-plate 2021 with a sliding groove 2022 on its inner side. The sliding groove 2022 slides along a sliding bar 2023 and a rack 2024. A compression spring 2025 is fixedly connected directly below the sliding bar 2023, and the lower part of the compression spring 2025 is fixedly connected to the bottom of the sliding groove 2022. The L-plate 2021 is fixedly disposed inside the cavity box 102. A first gear 2027 is fixedly connected between the L-plates 2021 through a bearing seat. A connecting shaft 2026 is provided, and the first gear 2027 and the second gear 2028 are meshed and connected. A second connecting shaft 2029 that is matched and connected to the bearing seat is also provided between the second gears 2028. A steel wire rope 20210 is fixedly connected to one side of the second connecting shaft 2029. One end of the steel wire rope 20210 passes through the connecting hole 104 and is fixedly connected to another side of the second connecting shaft 2029. A spike 20214 for inserting and turning carbon powder is fixedly connected to the lower middle part of the steel wire rope 20210.

[0056] The steel wire rope 20210 is provided in multiple strands, and each steel wire rope 20210 has multiple spikes 20214 fixed on its surface. The spikes 20214 are used to equidistantly penetrate and turn the carbon powder inside the carbon powder placement box 103. At the same time, during the reverse release of the steel wire rope 20210, the spikes 20214 can also use their own weight to penetrate into the carbon powder to remove clumps and lift and turn the powder.

[0057] See the attached diagram in the instruction manual. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Both ends of the wire rope 20210 are provided with branch suction pipes 20211 extending into the toner placement box 103, and one end of the branch suction pipe 20211 is fixedly connected to one end of the second powder conveying pump 20212. A second powder outlet pipe 20213 is installed and connected above the second powder conveying pump 20212, and the second powder outlet pipe 20213 extends through the limiting baffle 107 and into the frame body 101 and is matched with the conveying hole 2019.

[0058] Working Principle: When using this fully automatic pressing powder molding machine, when the tantalum capacitor core needs to be pressed, the second powder conveying pump 20212 starts working. When the second powder conveying pump 20212 is working, the toner inside the toner placement box 103 is conveyed through the branch suction pipe 20211 to the second powder outlet pipe 20213. The toner entering the second powder outlet pipe 20213 is then conveyed to the lower pressing mold 2018. During the toner extraction process of the second powder conveying pump 20212, the photoelectric sensor detects that the toner has been extracted to a certain height and transmits the detection signal to the controller. At this time, the controller controls the second powder conveying pump 20212... 12. Pause operation, then control the electric telescopic rod 20112 to operate. When the electric telescopic rod 20112 drives the lower pressing mold 2018 to slide along the guide groove 20110, it passes the displacement detection module. At this time, the displacement detection module controls the electric telescopic rod 20112 to drive the lower pressing mold 2018 to reciprocate for a certain period of time, so as to spread the internal toner. When the spread toner is conveyed by the scraper 20113 to the area directly below the upper pressing mold 2017, the operation of the electric telescopic rod 20112 stops. Then control the pressing cylinder 2012 to operate. When the pressing cylinder 2012 operates, it is driven by the through-hole plate 2011. The sliding block 2013 and guide rod 20114 slide downwards synchronously. When the guide rod 20114 slides downwards, it squeezes the rack 2024. At this time, the rack 2024 squeezes the compression spring 2025, which in turn drives the first gear 2027, the second gear 2028, and the second connecting shaft 2029 to rotate under force. When the second connecting shaft 2029 rotates under force, it coils and stretches the wire rope 20210, while simultaneously pulling the spike 20214 upwards to agitate the carbon powder in the middle and lower part. When the pressing cylinder 2012 drives the upper die 2017 to move upwards, the rack 2024 moves upwards synchronously. At this time, the wire rope 20210... When the 0210 is in the unloading state, the spike 20214 is inserted into the toner, which not only facilitates the removal of toner clumps but also facilitates subsequent reciprocating insertion and removal operations. After the tantalum capacitor core is pressed and formed, the unloading component inside the lower die 2018 performs unloading processing. After the tantalum capacitor core is unloaded, the displacement detection module detects that the lower die 2018 is in the initial position and controls the second powder conveying pump 20212 to run again to repeat the above operation. At the same time, during the toner conveying process, the first powder conveying pump 108 runs and conveys the excess toner through the first powder suction pipe 109 and the first powder outlet pipe 1010 to the toner placement box 103 for recycling.

[0059] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
