Description

Technical Field

[0001] The invention belongs to the field of tablet pressing, and in particular relates to an automatic tablet pressing station. Background Art

[0002] Currently, the tableting process for ceramic materials in the laboratory is largely manual. This process typically involves weighing the powder, pouring it into a mold, closing the top mold, feeding the mold into a manual tablet press for tableting, flipping it 180° to remove the material from the mold, and then wiping and cleaning the mold. This repetitive process is inefficient and tedious, leading to wasted time and manpower. This also causes R&D personnel to waste a significant amount of valuable time on non-R&D tasks, reducing overall work efficiency. Summary of the Invention

[0051] As attached Figure 1 -Attached Figure 12 As shown, the present invention provides an automatic tablet pressing station, including a mold storage rack 1, a consumable material storage rack 5, a powder feeding device 4, a tablet press 3, a mold cleaning device 2 and a manipulator 6;

[0052] The mold storage rack 1 is used to store molds 7, and the consumable material storage rack 5 is used to store powder material containers 8 and green billet trays 9, wherein the powder material container 8 is filled with a certain amount of powder material;

[0053] The powder feeding device 4 is used to feed powder to the lower mold 703 and the middle mold 702 after the mold 7 is assembled, thereby completing the feeding work of the mold 7;

[0054] The tablet press 3 is used to close the mold 7 filled with powder material, press the tablets and unload the tablets;

[0055] The mold cleaning device 2 is used to clean the mold 7 to prevent residual powder on the mold 7 from affecting the next use;

[0056] The manipulator 6 is used to transfer the mold 7 between the mold storage rack 1, the powder feeding device 4, the tablet press 3 and the mold cleaning device 2. Specifically, the lower mold 703 and the middle mold 702 of the mold 7 are transferred to the powder feeding device 4 for loading, and then transferred to the tablet press 3 for tableting, while the upper mold 701 of the mold 7 is directly transferred from the mold storage rack 1 to the tablet press 3 for tableting. The manipulator 6 is also used to transfer the powder material container 8 between the consumables storage rack 5 and the powder feeding device 4 to provide powder material for the lower mold 703 and the middle mold 702 of the mold 7. The manipulator 6 is also used to transfer the green compacts pressed by the tablet press 3 to the green compact tray 9, and then collect the pressed green compact materials.

[0057] The automatic tablet pressing station provided by the present invention can realize the full process automation of tablet pressing work, solving the problem that existing laboratories need to manually perform steps such as mold 7 feeding, mold closing, tablet pressing, tablet unloading, and cleaning. It can save the time of R&D personnel and significantly improve experimental efficiency. In specific work, tablet pressing operations and powder loading operations can be performed alternately, further improving work efficiency.

[0058] In one embodiment, the consumable material storage rack 5 further includes a powder loading intermediate rack 501 arranged on the side of the powder loading device 4;

[0059] The consumable material storage rack 5 is also used to store a powder tray 10 , on which a plurality of powder material containers 8 are mounted;

[0060] The robot 6 is also used to transfer the powder tray 10 between the consumables storage rack 5 and the powder loading intermediate rack 501 and to transfer the powder material container 8 between the powder loading intermediate rack 501 and the powder loading device 4.

[0061] In this embodiment, by setting up a powder loading transfer rack 501, the distance that the robot 6 transfers the powder material container 8 between the consumable storage rack 5 and the powder loading device 4 can be reduced. Since multiple powder material containers 8 can be set on the powder tray 10, the number of times the robot 6 moves between the consumable storage rack 5 and the powder loading device 4 can be reduced, thereby improving work efficiency.

[0062] In one embodiment, the consumables storage rack 5 includes three layers of storage racks. The upper storage rack is used to place the green billet tray 9 for the green billets to be collected. The space above the upper storage rack is empty to facilitate the robot 6 to place the green billets. Another layer is used to place the green billet tray 9 for the collected green billets, which can be the second layer or the third layer. Another layer is used to place the powder tray 10 containing the powder material container 8, which can be the third layer or the second layer.

[0063] In one embodiment, it also includes an outer cover 11, and the outer cover 11 is provided with sliding doors at the positions of the consumable storage rack 5, the mold storage rack 1 and the mold cleaning device 2, so as to facilitate manual replacement of the green tray 9, the powder material container 8 and the powder tray 10 of the consumable storage rack 5, facilitate manual replacement and maintenance of the mold 7 of the mold storage rack 1, and facilitate manual replacement and maintenance of the cleaning parts of the mold cleaning device 2.

[0064] In one embodiment, the manipulator 6 includes a ground rail manipulator body 601 and a gripping head 602;

[0065] Reference Attachment Figure 9 and attached Figure 10 The clamping head 602 includes two clamping plates 6021 that can move closer to and away from each other. The two clamping plates 6021 are driven by a linear reciprocating drive mechanism, such as an electric clamp. A mold and tray clamp 6022 is provided at one end of the clamping plate 6021. The mold and tray clamp 6022 is used to clamp the mold 7, the green body tray 9 and the powder tray 10. The other end is provided with a container and green body clamp 6023. The container and green body clamp 6023 is used to clamp the powder material container 8 and the green body. In this embodiment, one robot 6 can be used to clamp the mold 7, the green body tray 9, the powder tray 10, the powder material container 8 and the green body, with extremely high utilization rate, which can reduce the number of robots and reduce costs.

[0066] In one embodiment, the mold and tray chuck 6022 includes an arcuate groove arranged at one end of a clamping plate 6021. The two arcuate grooves can clamp the side wall of the mold 7 when combined, and the two clamping plates 6021 can directly clamp the green body tray 9 and the powder tray 10. The container and green body chuck 6023 includes two clamping rods arranged at the other end of a clamping plate 6021. The four clamping rods can be combined to clamp the powder material container 8 with a test tube structure and the sheet-like green body.

[0067] In one embodiment, the relative spacing between the two gripping plates 6021 at one end where the mold and tray chuck 6022 is provided is greater than the relative spacing between the two ends where the container and green body chuck 6023 is provided. Since the diameter of the powder material container 8 and the green body is smaller than the diameter of the mold 7 and the outer dimensions of the green body tray 9 and the powder tray 10, and the manipulator 6 is only in use of one of the mold and tray chuck 6022 or the container and green body chuck 6023 at a time, the spacing between the two container and green body chucks 6023 and the two mold and tray chucks 6022 can ensure that the mold and tray chuck 6022 and the container and green body chuck 6023 do not interfere with each other.

[0068] In this embodiment, the clamping head 602 can complete the clamping work of the mold 7, the green body tray 9, the powder tray 10, the powder material container 8 and the green body only through a linear reciprocating drive mechanism. Moreover, the size difference between the powder material container 8 and the green body and the mold 7, the green body tray 9 and the powder tray 10 is quite large, and the clamping head 602 can still perform clamping, with extremely high utilization rate, and the ground rail manipulator body 601 can ensure that the moving range of the clamping head 602 is large enough to facilitate the transfer of the above-mentioned objects between various devices, so as to solve the problem of time waste caused by manual transfer of various components.

[0069] In one embodiment, refer to the attached Figure 5 and attached Figure 6 , wherein the mold 7 includes an upper mold 701, a middle mold 702 and a lower mold 703, and the middle mold 702 is provided with a through hole 7021 running through the upper and lower ends. The cross-sectional shape of the through hole 7021 can be determined according to the shape required for tableting. For example, when a round cake-shaped blank needs to be pressed, the cross-section of the through hole 7021 is circular; when a rectangular-shaped blank needs to be pressed, the cross-section of the through hole 7021 is rectangular. The upper mold 701 includes a limiting portion 7012 and an upper mold rod 7013 arranged in sequence from top to bottom. The outer dimensions of the limiting portion 7012 and the upper mold rod 7013 are successively reduced to form a stepped structure. For example, when the limiting portion 7012 and the upper mold rod 7013 are both cylindrical mechanisms, the diameters of the limiting portion 7012 and the upper mold rod 7013 are successively reduced, and the upper mold rod 7013 can be inserted into the through hole 7021. The cross-sectional shape of the upper mold rod 7013 is consistent with the cross-sectional shape of the through hole 7021, and the sizes of the two are suitable. 7021, the cross-sectional shape of the lower die rod 7031 is consistent with the cross-sectional shape of the through hole 7021, and the two are adapted in size. The end face of the lower die rod 7031 is preferably a flat plate, and it can also be other required structures according to the structure required for the blank, and is specifically selected according to actual needs. The lower die 703 includes a lower die rod 7031 and a lower die base 7032 arranged in sequence from top to bottom, and the lower die rod 7031 can be inserted into the through hole 7021. The cross-sectional shape of the lower die rod 7031 is consistent with the cross-sectional shape of the through hole 7021, and the two are adapted in size. The end face of the lower die rod 7031 is preferably a flat plate, and it can also be other required structures according to the structure required for the blank, and is specifically selected according to actual needs. The lower end of the upper die rod 7013, the inner wall of the through hole 7021 and the upper end of the lower die rod 7031 enclose a mold cavity, and the upper end face of the blank formed by the mold cavity is consistent with the end face structure of the lower end of the upper die rod 7013, the lower end face is consistent with the end face structure of the upper end of the lower die rod 7031, and the side wall is consistent with the cross-sectional shape of the through hole 7021;

[0070] Reference Attachment Figure 7 -Attached Figure 8 The tablet press 3 provided by the present invention includes a middle die support limit plate 307, an upper die molding mechanism, a lower die molding mechanism and an upper die support mechanism;

[0071] The middle die support and limit plate 307 is provided with a middle die limit through hole 30701, and the middle die limit through hole 30701 is used to set up the middle die 702. During tableting, the middle die 702 is set up on the middle die limit through hole 30701 and limited on the middle die support and limit plate 307;

[0072] The upper die pressing mechanism includes a first linear motion mechanism 3019 disposed above the middle die support limit plate 307 and toward the upper end of the middle die limit through hole 30701. The output end of the first linear motion mechanism 3019 is used to abut the end of the limit portion 7012 of the upper die 701, thereby driving the upper die 701 to move toward the middle die 702 for tablet pressing. When the upper die 701 has an abutment portion 7011, the output end of the first linear motion mechanism 3019 is used to abut the end of the abutment portion 7011 of the upper die 701.

[0073] The lower die pressing mechanism includes a second linear motion mechanism 301 disposed below the middle die support limit plate 307 and toward the lower end of the middle die limit through hole 30701. A lower die placement platform 306 supporting the lower die base 7032 is disposed at the output end of the second linear motion mechanism 301, thereby driving the lower die 703 toward the middle die 702 for tableting.

[0074] The upper mold support mechanism includes a buffer guide column 309 arranged on the middle mold support limit plate 307, a buffer support head 3012 slidingly arranged on the buffer guide column 309 along the output direction of the first linear moving mechanism 3019, and an elastic member used to make the buffer support head 3012 always have a moving tendency in the direction away from the middle mold support limit plate 307. Preferably, the elastic member is a spring 3010 sleeved on the buffer guide column 309, one end of the spring 3010 abuts against the buffer support head 3012, and the other end abuts against the middle mold support limit plate 307. The buffer support head 3012 is provided with an interlocking groove I301201, and the upper end of the interlocking groove I301201 is used to support the lower end surface of the limiting portion 7012 of the upper mold 701, and the upper mold rod 7013 of the upper mold 701 passes through the interlocking groove I301201 to enter and exit the through hole 7021 of the middle mold 702.

[0075] The upper die support mechanism provided by the present invention is used, on the one hand, to support the upper die 701 and provide an installation position for the upper die 701. On the other hand, it can realize the buffer protection automatic tableting function. Specifically, during tableting, the output end of the first linear motion mechanism 3019 abuts against the abutment portion 7011 of the upper die 701 and pushes it to move downward. In the process, the lower end surface of the limiting portion 7012 will drive the buffer support head 3012 to move downward, and the buffer support head 3012 will compress the elastic part to store force. When the tableting is completed and the material is removed, in order to avoid the possibility of the first linear motion mechanism 3019 and the second linear motion mechanism 301 being difficult to ensure synchronization during the removal of the material, the upper die 7011 can be used as a buffer protection mechanism. When the middle mold 702 is pressed, the second linear motion mechanism 301 will slightly precede the first linear motion mechanism 3019 to descend a small distance and then stop at a certain position, and then the first linear motion mechanism 3019 will eject the blank. When the upper mold support mechanism of the present invention is not provided, the upper mold 701 may simultaneously free fall and impact the blank. At this time, the buffer support head 3012 of the upper mold support mechanism of the present invention supports the upper mold 701 and prevents it from free falling, protecting the falling blank from landing safely on the lower mold 703, and realizing the buffer protection automatic tableting function. On the other hand, it can also assist the demoulding of the upper mold 701 and the middle mold 702. Specifically, after the first linear motion mechanism 3019 is reset, the reset force of the elastic member will drive the buffer support head 3012 to reset. At this time, the buffer support head 3012 will drive the upper mold 701 to move up a certain distance, so that the upper mold 701 and the middle mold 702 are separated. Finally, the elastic travel of the elastic member of the upper mold support mechanism can also prevent the upper mold 701 from overshooting, ensuring the quality of tableting.

[0076] The mold provided by the present invention consists of three parts: an upper mold 701, a middle mold 702 and a lower mold 703, which is convenient for configuring the mold cavity, thereby realizing multi-shape powder pressure molding and customized shape powder molding. Moreover, the mold is convenient for loading powder and removing blanks after tableting. At the same time, it is also convenient for cleaning various parts of the mold cavity so that the mold can be reused.

[0077] The upper die pressing mechanism and the lower die pressing mechanism provided by the present invention can achieve high-precision tableting and stripping by controlling the position and pressure of the first linear motion mechanism 3019 and the second linear motion mechanism 301, and the blank will not be crushed during stripping.

[0078] In one embodiment, the tablet press 3 further includes a demoulding mechanism, and the upper mold 701 further includes an abutment portion 7011 provided at one end of the limiting portion 7012 away from the upper mold rod 7013. In this embodiment, the upper mold 701 includes an abutment portion 7011, a limiting portion 7012 and an upper mold rod 7013 sequentially arranged from top to bottom, and the outer dimensions of the abutment portion 7011, the limiting portion 7012 and the upper mold rod 7013 are successively smaller to form a stepped structure. For example, at the abutment portion 7011, the limiting portion 7012 and the upper mold rod 7013, the outer dimensions of the abutment portion 7011, the limiting portion 7012 and the upper mold rod 7013 are successively smaller to form a stepped structure. When the upper mold portion 7012 and the upper mold rod 7013 are all cylindrical mechanisms, the diameters of the abutting portion 7011, the limiting portion 7012 and the upper mold rod 7013 become smaller in sequence. The demoulding mechanism is used to separate the upper mold 701 and the middle mold 702 when the upper mold 701 and the middle mold 702 cannot be separated due to the powder material being stuck. The demoulding mechanism includes a demoulding seat 308 provided on the middle mold support and limiting plate 307 and a demoulding head 3017 provided on the output end of the first linear motion mechanism 3019;

[0079] The demolding base 308 is provided with a placement cavity 30801, and an inlet and outlet 30802 is provided at one end of the placement cavity 30801. The inlet and outlet 30802 is located above the placement cavity 30801 and is provided with an engaging groove II 30803. The engaging groove II 30803 is used to engage with the side wall of the limiting portion 7012 of the upper mold 701. When the upper mold 701 and the middle mold 702 are stuck, the upper mold 701 and the middle mold 702 are placed in the placement cavity 30801 through the inlet and outlet 30802. At this time, the middle mold 702 is located in the placement cavity 30801, the limiting portion 7012 of the upper mold 701 is engaged with the engaging groove II 30803, and the abutting portion 7011 of the upper mold 701 is located above the placement cavity 30801.

[0080] The demoulding head 3017 includes a demoulding plate 301701 and an engaging groove III 301702 provided on the demoulding plate 301701. The upper end of the engaging groove III 301702 is used to mount the lower end surface of the abutting portion 7011 of the upper mold 701. The engaging groove III 301702 is used to engage the side wall of the limiting portion 7012 of the upper mold 701. When demoulding, the first linear moving mechanism 3019 drives the demoulding plate 301701 to the top of the placement cavity 30801 and ensures that the engaging groove III 301702 and the engaging groove II 30803 are aligned. At this time, the upper mold 701 and the middle mold 702 are placed in the placement cavity 30801. 1, the limiting portion 7012 of the upper mold 701 will engage with the interlocking groove III 301702 at the same time, and the lower end surface of the abutting portion 7011 of the upper mold 701 will engage with the upper end of the interlocking groove III 301702. At this time, it is only necessary for the first linear moving mechanism 3019 to reset and move upward, and the demolding template 301701 will pull the upper mold 701 to move upward, while the middle mold 702 cannot move due to the limiting of the placement cavity 30801, and then the stuck upper mold 701 and the middle mold 702 are forcibly separated by mechanical pulling force, and the separation direction is consistent with the separation direction of the upper mold 701 and the middle mold 702, which can reduce the loss to the upper mold 701 and the middle mold 702. In this embodiment, the separation driving force is achieved through the first linear motion mechanism 3019. This mechanism is effectively utilized, serving as both a mold closing driving force and a mold opening driving force when the upper mold 701 and the middle mold 702 become stuck. Furthermore, the mold stripping base 308 and the mold stripping head 3017 are positioned directly on the tableting station side of the upper mold 701 and the middle mold 702. This reduces the travel path of the upper mold 701 and the middle mold 702 during mold opening, improving mold opening efficiency.

[0081] The tablet press 3 provided by the present invention can perform tablet pressing process, material removal process and mold removal process;

[0082] The tableting process comprises:

[0083] S11, inserting the lower mold rod 7031 into the through hole 7021 to complete the mold closing of the middle mold 702 and the lower mold 703, and injecting powder material into the mold cavity through the upper end of the through hole 7021;

[0084] S12: Control the second linear motion mechanism 301 to drive the lower mold placement platform 306 into the middle mold limiting through hole 30701, and place the closed middle mold 702 and lower mold 703 on the middle mold limiting through hole 30701, with the lower mold 703 supported on the lower mold placement platform 306;

[0085] S13, placing the upper mold 701 on the buffer support head 3012, with the lower end surface of the limiting portion 7012 of the upper mold 701 placed on the upper end of the fitting groove I 301201, and the upper mold rod 7013 of the upper mold 701 aligned with the through hole 7021 of the middle mold 702;

[0086] S14, the first linear motion mechanism 3019 and / or the second linear motion mechanism 301 are in operation. Preferably, the second linear motion mechanism 301 maintains the upper limit position of the lower die placement table 306, and the first linear motion mechanism 3019 drives the upper die 701 downward, so that the upper die 701 and the lower die 703 are relatively close to each other, and the upper die rod 7013 and the lower die rod 7031 are relatively close to squeeze the powder to complete tableting;

[0087] In this tableting process, the first linear motion mechanism 3019 and the second linear motion mechanism 301 can be controlled to precisely control position and pressure, and the pressurization, pressure holding, and pressure relief process flows can be flexibly customized to achieve customized tableting.

[0088] The stripping process includes:

[0089] S21, the second linear motion mechanism 301 is reset to a certain distance, so that the lower mold rod 7031 is relatively away from the upper mold rod 7013;

[0090] S22, the first linear motion mechanism 3019 continues to move, causing the upper mold rod 7013 and the blank to separate from the through hole 7021, and the blank falls into the upper end of the lower mold rod 7031;

[0091] S23, the first linear motion mechanism 3019 is reset, and the elastic member drives the buffer support head 3012 to reset, thereby driving the upper mold 701 to move toward the end away from the lower mold 703;

[0092] S24, remove the blank and the mold to complete the stripping.

[0093] When a conventional tablet press unloads material, it is difficult to ensure the synchronization of the first linear motion mechanism 3019 and the second linear motion mechanism 301, and the blank may be crushed when it comes out of the middle mold. The second linear motion mechanism 301 of the present invention will descend a small distance slightly before the first linear motion mechanism 3019 and then stop at a certain position, and then the blank is ejected by the first linear motion mechanism 3019. When the upper mold support mechanism of the present invention is not provided, the upper mold 701 may freely fall and impact the blank at the same time. At this time, the buffer support head 3012 of the upper mold support mechanism of the present invention supports the upper mold 701 and prevents it from free falling, protecting the falling blank from safely landing on the lower mold 703, thereby realizing the buffer protection automatic tableting function.

[0094] At the same time, in this demoulding process, the upper mold 701 and the middle mold 702 are automatically demoulded through the upper mold support mechanism, thereby improving the demoulding work efficiency.

[0095] If the upper die 701 and the middle die 702 are stuck, the tablet press 3 also has a demolding process:

[0096] The demoulding process includes:

[0097] S31, the first linear motion mechanism 3019 drives the demolding plate 301701 to the top of the placement cavity 30801 and ensures that the interlocking groove III 301702 and the interlocking groove II 30803 are aligned. The upper mold 701 and the middle mold 702 are placed in the placement cavity 30801 through the inlet and outlet 30802. At this time, the middle mold 702 is located in the middle and lower part of the placement cavity 30801, and the limiting portion 7012 of the upper mold 701 is engaged with the interlocking groove II 30803 and the interlocking groove III 301702, while the abutting portion 7011 of the upper mold 701 is located above the placement cavity 30801.

[0098] S32, the first linear moving mechanism 3019 moves upward, the demolding plate 301701 pulls the upper mold 701 upward, while the middle mold 702 cannot move due to the limit of the placement cavity 30801, and then the stuck upper mold 701 and middle mold 702 are forcibly separated by mechanical pulling force.

[0099] Since the separation direction is consistent with the separation direction of the upper mold 701 and the middle mold 702, damage to the upper mold 701 and the middle mold 702 can be reduced. In addition, the separation driving force is achieved by the first linear motion mechanism 3019, which is effectively utilized so that the first linear motion mechanism 3019 can serve as both the mold closing driving force and the mold opening driving force when the upper mold 701 and the middle mold 702 are stuck.

[0100] In one embodiment, refer to the attached Figure 11 and attached Figure 12 The powder feeding device includes a rotating placement platform 401 and a powder pouring mechanism 402. The rotating placement platform 401 includes a rotating mechanism 40101 and a placement platform 40102 arranged at the output end of the rotating mechanism 40101. The placement platform 40102 is used to place the mold 7 to be loaded. The loading port of the mold 7 (the upper end of the through hole 7021) is arranged upward. The rotating mechanism 40101 is used to drive the placement platform 40102 and the mold 7 to rotate during the pouring process, so that the powder enters the mold cavity of the mold 7 and remains uniform and solid, and will not form a sand cone shape that affects the final tablet molding.

[0101] The powder pouring mechanism 402 includes a rotating motor 40201 and a chuck 40202 arranged at the output end of the rotating motor 40201. The chuck 40202 is used to clamp the powder material container 8. The rotating motor 40201 is used to drive the powder material container 8 to tilt and then swing to realize pouring. The powder material container 8 swings about the rotation axis of the rotating motor 40201 when pouring powder. On the one hand, it can ensure that the powder material in the powder material container 8 is poured out cleanly to avoid the retention of powder material in the powder material container 8. On the other hand, it can make the powder material have a lateral movement trend in the process of entering the mold cavity. The landing point of the powder material in the mold cavity will be more dispersed, which can increase the distribution area, thereby avoiding the concentrated accumulation of powder material.

[0102] The combined use of the rotating placement platform 401 and the powder pouring mechanism 402 of the present invention can ensure that the powder material is evenly distributed in all directions in the mold cavity after it is loaded into the mold cavity. The upper end of the powder material is relatively flat, and the stress distribution can be evenly distributed during tableting in the mold cavity, so that the powder green body is evenly stressed, thereby ensuring the tableting success rate and quality, and at the same time ensuring the service life of the mold 7.

[0103] In one embodiment, the powder pouring mechanism 402 further includes a three-axis mobile platform 40203, and the rotary motor 40201 is disposed at the output end of the three-axis mobile platform 40203;

[0104] The three-axis moving platform 40203 can drive the outlet of the powder material container 8 to align with the feed port of the mold 7, thereby ensuring that the poured powder material from the powder material container 8 is aligned with the feed port of the mold 7, preventing the powder material from being poured to other places. The three-axis moving platform 40203 can also drive the powder material container 8 to move up and down during the pouring process of the powder material container 8, which can also prevent the powder material from being retained in the powder material container 8, and can also improve the uniformity of pouring into the mold cavity and reduce concentrated accumulation. The three-axis moving platform 40203 can also invert the powder material container 8 to above the feed port of the mold 7 after pouring the powder material container 8. At this time, the powder material can be further prevented from being retained in the powder material container 8, and all the powder materials in the powder material container 8 can be poured into the pouring cavity. During this process, the three-axis moving platform 40203 can also move up and down, thereby further enhancing the pouring effect.

[0105] In this embodiment, the addition of a three-axis mobile platform 40203 significantly improves the accuracy, quality and completion of material pouring.

[0106] In one embodiment, after the mold completes the tableting process, powder will adhere to the mold components, which will affect the mold release during subsequent use and even affect the flatness of the tablets. Therefore, each mold needs to be cleaned after use;

[0107] The present invention also provides a mold cleaning device 2, which includes a mold rod cleaning mechanism, a through-hole cleaning mechanism, and a blower mechanism;

[0108] The mold rod cleaning mechanism includes an adsorption material 201 and a cleaning hole 20101 provided on the adsorption material 201. The manipulator 6 can insert the upper mold rod 7013 and the lower mold rod 7031 into the cleaning hole 20101 for cleaning. The adsorption material 201 can adsorb the powder material of the upper mold rod 7013 and the lower mold rod 7031, thereby ensuring the cleaning effect. Preferably, the adsorption material 201 is a sponge or foam. At the same time, the adsorption material 201 can also adsorb cleaning liquid, such as alcohol, and then the upper mold rod 7013 and the lower mold rod 7031 can be inserted into the cleaning hole 20101. During cleaning, the upper mold rod 7013 and the lower mold rod 7031 can be wiped with alcohol to further thoroughly clean the residual powder; in actual use, the manipulator 6 drives the upper mold rod 7013 and the lower mold rod 7031 to be inserted into the cleaning hole 20101, and pumps them up and down multiple times to improve the cleaning effect. After the side walls of the upper mold rod 7013 and the lower mold rod 7031 are cleaned, the end faces of the upper mold rod 7013 and the lower mold rod 7031 can be driven by the manipulator 6 to move to the end face of the adsorption material 201 for friction, so as to clean the end faces of the upper mold rod 7013 and the lower mold rod 7031;

[0109] The through-hole cleaning mechanism includes a middle mold placement seat 202 and a cleaning rod 203. The middle mold placement seat 202 is used to place the middle mold 702. The manipulator 6 can drive the cleaning rod 203 to clean the through-hole 7021. The middle mold placement seat 202 is used to place the middle mold 702, so that the manipulator 6 can drive the cleaning rod 203 to accurately locate the through-hole 7021 of the middle mold 702 for cleaning. At the same time, it is also convenient to collect the cleaning liquid of the cleaning rod 203. During specific use, the manipulator 6 drives the cleaning rod 203 to enter the through-hole 7021 and pumps it up and down multiple times to improve the cleaning effect. In this embodiment, the manipulator 6 is also used to clamp the cleaning rod 203 to further improve its utilization rate. Specifically, the cleaning rod 203 is clamped by the container of the manipulator 6 and the green body chuck 6023.

[0110] In one embodiment, the adsorption material 201 and the cleaning rod 203 are both soaked in a cleaning liquid, and the cleaning liquid is preferably alcohol, which is easy to volatilize, thereby avoiding the situation where the powder is not agglomerated inside the mold due to the cleaning liquid not being blown dry; the cleaning rods 203 are provided in plurality, and the through-hole cleaning mechanism also includes a cleaning rod placement seat 204 for accommodating a plurality of the cleaning rods 203, and the cleaning rod placement seat 204 is provided with a cleaning liquid receiving tank. When there is no cleaning work, the cleaning rod 203 is placed in the receiving tank. Similarly, there are multiple cleaning rods 203, so that after a cleaning rod 203 has cleaned one or more middle molds 702, a lot of powder is retained in the cleaning rod 203 and it is no longer used. At this time, the robot 6 can replace a cleaning rod 203 to clean the middle mold 702 to ensure the cleaning effect.

[0111] The blowing mechanism includes an air outlet, and the manipulator 6 can drive the upper mold rod 7013, the lower mold rod 7031 and the through hole 7021 to the air outlet to blow dry and blow away the powder material, that is, the blowing mechanism can be used to blow away the powder material to further improve the cleaning effect of the mold. When the cleaning rod 203 and the adsorption material 201 are both soaked with cleaning liquid to improve the cleaning effect, the blowing mechanism can also blow dry the cleaning liquid, thereby preventing the powder from clumping and sticking to the inside of the mold due to the residual cleaning liquid during the next use. In a preferred embodiment, the lower end of the middle mold placement seat 202 is provided with an air outlet 20201, and the air outlet of the blowing mechanism is connected to the air outlet 20201. In this embodiment, the blowing mechanism is combined with the middle mold placement seat 202, which can improve the compactness of the structure and can also directly blow the through hole 7021 of the middle mold 702 after cleaning, thereby improving the cleaning efficiency of the middle mold 702.

[0112] The mold cleaning device 2 provided by the present invention can thoroughly clean each position of the mold cavity of the mold 7 to avoid residual powder on the mold affecting the next use. The mold transfer utilizes the robot 6, which solves the problem of manual mold removal, mold cleaning and multi-position transfer of the mold, resulting in time waste. The robot 6 can also be used for other processes such as mold loading and unloading, greatly improving the utilization rate of the robot 6. The mold rod cleaning mechanism can efficiently clean the side walls and end faces of the upper mold rod 7013 and the lower mold rod 7031, while the through-hole cleaning mechanism can clean the through-hole 7021 of the middle mold 702. The air blowing mechanism can be used to blow away the powder material to further improve the cleaning effect of the mold. When the cleaning rod 203 and the adsorption material 201 are both soaked in cleaning liquid to improve the cleaning effect, the air blowing mechanism can also blow the cleaning liquid dry, thereby preventing the powder from clumping and sticking to the inside of the mold due to the residual cleaning liquid during the next use.

[0113] The present invention also provides a tableting method, using the above-mentioned automatic tableting station, comprising the following steps:

[0114] S1, placing the powder material container 8 and the green body tray 9 on the consumable material storage rack 5;

[0115] S2, the manipulator 6 transfers the combined lower mold 703 and middle mold 702 of the mold 7 from the mold storage rack 1 to the powder loading device 4, and transfers the powder material container 8 to the powder loading device 4, and the powder loading device 4 loads the powder material in the powder material container 8 into the combined lower mold 703 and middle mold 702;

[0116] S3, the manipulator 6 transfers the loaded lower mold 703 and the middle mold 702 from the powder loading device 4 to the tablet press 3, and transfers the upper mold 701 of the mold 7 on the mold storage rack 1 to the tablet press 3, and the tablet press 3 performs tableting;

[0117] During the tableting process of the tablet press 3 , the robot 6 can transfer the powder material container 8 after emptying to the consumable material storage rack 5 , and the robot 6 can perform a new round of step S2 ;

[0118] S4, after the tablet press 3 completes tableting, the robot 6 transfers the green billet to the green billet tray 9, and transfers the mold 7 to the mold cleaning device 2 for cleaning, and then transfers it to the mold storage rack 1 after cleaning.

[0119] The above description is merely an embodiment and does not limit the present invention in any way. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes, modifications, or modifications to the technical solution of the present invention into equivalent embodiments with equivalent changes using the technical content disclosed above.
