Description

Technical Field

[0001] The invention relates to the technical field of tablet presses, and in particular to chip packaging production equipment and a chip packaging production method. Background Art

[0002] The tablet press is a machine used in the pharmaceutical industry to place granular or powdered materials in the middle die hole and press them into tablets by a punch. The rotary tablet press is a tablet press that drives the mold through the rotation of the turret to complete functions such as filling, metering, pressing, and tablet arrangement. It is the mainstream method of modern production tablet presses. The tablet press turret is one of the core components of the tablet press. Its function is to load the mold and drive the mold to rotate so that the mold passes through each station of the tablet pressing process in turn to complete the production of tablets. The mold holes are evenly distributed on the distribution circle of the tablet press turret. The core tablet is a special tablet form, which is characterized by the core tablet being wrapped in a formed tablet, which can be released in different parts of the human body. In the prior art, when producing core tablets, a core tablet turret similar to the tablet press turret is manufactured, and the core tablet turret distributes the core tablets. During the operation of the tablet press, the tablet press turret is in a rotating state, and the tablet core turret is driven by the gears on the tablet press turret or by a direct drive motor, and is also in a rotating state. The rotation speed is in a specific ratio to the rotation speed of the tablet press turret, so that the middle die holes of the turret are successively concentric with the tablet core on the tablet core turret at the tangent points of the trajectory. At the moment when the tangent points are concentric, the tablet core is filled into the middle die hole by relying on the gravity of the tablet core or forced downward pressure to realize the filling of the tablet core.

[0003] However, the above structure requires that the core be filled into the middle mold hole at the moment when the core and the middle mold hole overlap at the tangent point of the pitch circle. Theoretically, the overlap time is only a moment, which can easily cause a large concentricity deviation of the core, resulting in a low pass rate of core production. On the other hand, on the core turret in the prior art, the middle mold distribution plate is integrally processed, and the center distance from each core mold to the core turret is fixed. When the concentricity of individual cores is poor, the core mold with a large concentricity deviation cannot be adjusted individually, and the practicality is poor. Therefore, a chip packaging production device and a chip packaging production method are proposed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a chip packaging production equipment, which solves the technical problem that when the existing chip packaging production equipment is punching the core, the core is filled into the middle mold hole at the moment when the core and the middle mold hole coincide at the tangent point of the pitch circle.

[0023] After the chip core is transported to the fixed substrate, the chip core mold is controlled to drive the chip core to rotate on the fixed substrate;

[0024] When the tablet core moves to the top of the middle die hole, the guide groove guides the telescopic shaft pin to move with the axis of the tablet press turret as the axis, and the tablet core and the middle die hole directly below it have the same movement trajectory.

[0029] Compared with the above background technology, the present invention provides a chip packaging production equipment, which has the following beneficial effects:

[0030] (1) When the tablet core moves to the top of the middle mold hole in the present invention, the guiding effect of the guide groove on the telescopic shaft pin and the limiting effect of the tablet core turret on the telescopic shaft pin, before the tablet core reaches the filling position, the movement trajectory of the telescopic shaft pin is changed from rotating along the shaft core to rotating along the axis of the tablet press turret, so that the tablet core moves with the axis of the tablet press turret as the axis center. When the tablet core coincides with the horizontal plane of the center of the middle mold hole, the movement trajectory of the tablet core and the middle mold hole directly below it is the same. The coincidence process of the tablet core and the middle mold hole changes from coincidence at the tangent point to coincidence of a section of the trajectory, effectively extending the coincidence time of the tablet core and the middle mold hole, ensuring that the tablet core is always directly above the corresponding middle mold hole within a certain period of time, so that the tablet core has sufficient time to be filled into the middle mold hole, thereby reducing the concentricity deviation of the tablet core and improving the qualified rate of chip packaging production. The chip packaging production method adopted in the present invention also has the above beneficial effects.

[0031] (2) The telescopic shaft in the present invention is connected to the core mold by a locking bolt. The center distance from each core mold to the core turret can be adjusted individually.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, a chip packaging production equipment includes: a frame and a tablet press turret 1 arranged on the frame.

[0051] A driving device is arranged on the frame, and the driving device is used to drive the tablet press turret 1 to rotate. A plurality of middle die holes are arranged in an array on the tablet press turret 1, and the middle die holes are used to assist in punching tablet cores.

[0052] The frame is also provided with a tablet core distribution device 4, which includes: a fixed base plate 6 arranged on the frame, the fixed base plate 6 is arranged on one side of the tablet press turret 1, a tablet core turret 11 is arranged on the fixed base plate 6, the tablet core turret 11 is connected to the transmission base plate 12, the transmission base plate 12 is connected to the shaft core 13, and the shaft core 13 is connected to the tablet press turret 1 through a transmission assembly. The tablet core turret 11, the transmission base plate 12 and the shaft core 13 are fastened together by bolts and positioning pins, and the transmission assembly includes: a first gear 2 arranged on the tablet press turret 1 and a second gear 3 arranged on the fixed base plate 6, the first gear 2 and the second gear 3 are meshed with each other, and the shaft core 13 is further meshed and connected to the second gear 3 through a gear set.

[0053] like Figure 4 , Figure 5 and Fig.13 As shown, a plurality of core molds 16 are arranged in an array above the core turret 11, and the core mold 16 is used to transport the core; specifically, a hook-shaped structure is provided on the outer peripheral side of the core mold 16, and when the core mold 16 rotates forward, the hook-shaped structure can hook the core, driving the core to rotate forward with the core mold 16 until the core is transported to the top of the middle mold hole.

[0054] The fixed base plate 6 is fixedly connected to the plane cam 14 , and the plane cam 14 is rotatably connected to the shaft core 13 . A guide groove 30 is provided on the bottom surface of the plane cam 14 .

[0055] A plurality of telescopic shaft pins 20 are arranged in an array on the top surface of the core turret 11. The axial direction of the telescopic shaft pins 20 is perpendicular to the top surface of the core turret 11. The upper end of the telescopic shaft pin 20 is rotatably connected to the guide groove 30. Specifically, when the core turret 11 is driven to rotate forwardly by the transmission bottom plate 12, the core turret 11 drives the telescopic shaft pin 20 to rotate forwardly. Since the planar cam 14 is fixed, the upper end of the telescopic shaft pin 20 moves relative to the guide groove 30. In addition, a plurality of telescopic shafts 18 are arranged in an array inside the core turret 11. The telescopic shaft 18 is connected to the lower end of the telescopic shaft pin 20. The left end of the telescopic shaft 18 is locked by Bolt 17 connects the core mold 16. When the concentricity of individual cores is poor, the locking bolt 17 on the core mold 16 corresponding to the core is loosened, and the relative position of the core mold 16 on the telescopic shaft 18 is flexibly adjusted before tightening the locking bolt 17. Specifically, the core mold 16 is adjusted along the radial direction of the core turret 11 to ensure that each core mold 16 can convey the core to the top of the corresponding middle mold hole, that is, the center distance from each core mold 16 to the core turret 11 can be adjusted individually, which effectively improves the situation where the concentricity deviation of the core corresponding to the core mold 16 is large.

[0056] Specifically, a notch is provided in the middle of the telescopic shaft 18, and a threaded hole is provided at the rear end of the telescopic shaft 18, and the threaded hole passes through one side of the notch. After the lower end of the telescopic shaft pin 20 is inserted into the notch, a bolt rod is assembled in the threaded hole, and the left end of the bolt rod supports the lower end of the telescopic shaft pin 20, so that the telescopic shaft pin 20 is locked and connected to the telescopic shaft 18. Further, a groove is provided at the lower end of the telescopic shaft 18, and when the bolt rod is assembled in the threaded hole, the left end of the bolt rod directly supports the groove, and the groove can prevent the telescopic shaft pin 20 from falling off, thereby improving the stability of the telescopic shaft pin 20 when connected to the telescopic shaft 18.

[0057] like Fig.12As shown, when in use, when the tablet press turret 1 rotates, the shaft core 13 is driven to rotate through the transmission assembly, and the shaft core 13 drives the tablet core turret 11 to rotate synchronously, and the tablet core enters the tablet core turret 11 through the notch on the distribution plate track ring 7, and the tablet core mold 16 drives the tablet core to rotate on the fixed base plate 6; when the tablet core moves to just above the middle mold hole, the guide groove 30 guides the telescopic shaft pin 20 to move with the axis of the tablet press turret 1 as the axis center, and the guiding effect of the guide groove 30 on the telescopic shaft pin 20 and the limiting effect of the tablet core turret 11 on the telescopic shaft pin 20, when the tablet core reaches the filling position Before being placed, the movement trajectory of the telescopic shaft pin 20 is changed from rotating along the shaft core 13 to rotating along the axis of the tablet press turret 1, so that the core moves with the axis of the tablet press turret 1 as the axis. At this time, the movement trajectory 32 of the core is the same as the movement trajectory 31 of the middle die hole directly below it. For a certain period of time, the core is always directly above the corresponding middle die hole, which effectively prolongs the overlap time between the core and the middle die hole, allowing the core to have sufficient time to be filled into the middle die hole, and can accurately complete the subsequent punching of the chip package, reduce the concentricity deviation of the core, and effectively improve the qualified rate of chip package production.

[0058] A distribution disk track ring 7 is provided on the fixed base plate 6, and the distribution disk track ring 7 is fixed on the transmission fixed base plate 6 by bolts and positioning pins. The core is transported by a transmission belt and enters the core turret 11 through the notch on the distribution disk track ring 7. The distribution disk track ring 7 is arranged on the outer peripheral side of the core turret 11, and is mainly used to limit the movement path of the core, to prevent the core from being thrown out due to centrifugal force when the core mold 16 drives the core to rotate on the fixed base plate 6, and to ensure the stability of the position of the core during transportation.

[0059] like Figure 6 As shown, a core clamp 26 is provided on the distribution disk track ring 7, wherein the core clamp 26 is arranged at the end of the distribution disk track ring 7, and the core clamp 26 is connected to the distribution disk track ring 7 through a plurality of spring pins 28, and the two ends of the spring pins 28 are respectively connected to the distribution disk track ring 7 and the core clamp 26 by bolts, that is, the core clamp 26 can move in a directional manner relative to the distribution disk track ring 7, and before the core mold 16 drives the core to separate from the fixed base plate 6 and move to the tablet press turret 1, the core mold 16 approaches the core clamp 26, and the core clamp 26 cooperates with the core mold 16 to clamp the core, thereby preventing the core from falling directly onto the tablet press turret 1 before reaching directly above the middle mold hole.

[0060] It should be noted that the spring pin 28 has a certain elastic expansion and contraction function. While always clamping the core, it prevents the core mold 16 and the core clamping plate 26 from rigidly contacting and damaging the core, thereby protecting the core.

[0061] In one embodiment of the present invention, a core pressing block 22 is provided on the top of each core mold 16, and a core pressing pin 25 is provided on the core pressing block 22. The core pressing pin 25 is fixed to the core pressing block 22 by bolts. Furthermore, a fixed cover plate 10 is provided on the fixed base plate 6, and the fixed cover plate 10 is fixed to the fixed base plate 6 by a positioning handle 8 and a locking rod 9. The fixed cover plate 10 is covered and arranged on the circumferential outer side of the core turret 11 to protect the core turret 11 and prevent the core from being polluted by the external environment. A core pressing wheel device 5 is provided on the fixed cover plate 10. Among them, a positioning protrusion 2201 is provided on the top surface of the core pressing block 22, and the two ends of the positioning protrusion 2201 are smoothly connected to the top surface of the core pressing block 22. When the core pressing block 22 moves to the bottom of the core pressing wheel device 5, the core pressing wheel device 5 presses the core pressing block 22 downward by pressing the positioning protrusion 2201, and the core pressing block 22 drives the core pressing needle 25 to move downward until the core pressing needle 25 pushes the core into the middle mold hole for stamping.

[0062] It should be noted that the core pressing block 22 is fixed to the core mold 16 by connecting bolts 23 and a return spring 24, that is, under the downward pressure of the core pressing wheel device 5, the core pressing block 22 can move downward a certain distance relative to the core mold 16 to ensure that the core pressing needle 25 can push the core into the middle mold hole for stamping, and the function of the return spring 24 is to push the core pressing block 22 to return to its initial position when the core pressing wheel device 5 is no longer acting on the core pressing block 22, so that the core pressing needle 25 can be pulled out of the middle mold hole.

[0063] like Fig.10 As shown, in one embodiment of the present invention, the core pressing wheel device 5 includes: a mounting block 501, a mounting groove is provided on the fixed cover plate 10, the mounting block 501 is fixedly connected in the mounting groove by a bolt rod, an assembly frame 502 is provided on the mounting block 501, wherein the assembly frame 502 is connected to the assembly block 504 by a plurality of limiting bolts 503, specifically, a guide rail groove is provided on the left end of the assembly frame 502, the assembly block 504 is slidably connected in the guide rail groove, one side of the assembly block 504 is rotatably connected to the pressing wheel, and the pressing wheel is used to press the core pressing block 22, one of the limiting bolts 503 passes through the assembly frame 502 and is connected to the top surface of the assembly block 504, and by screwing this limiting bolt 503, the height of the core pressing wheel 505 relative to the core turret 11 can be accurately adjusted, so that the core pressing needle 25 can provide appropriate punching force during punching, thereby improving the qualified rate during chip packaging production.

[0064] like Figure 8As shown, the guide groove 30 is in an annular shape as a whole, and the guide groove 30 includes: an integrally formed guide section 3001 and a redirecting section 3002, the redirecting section 3002 is in an arc shape as a whole, and the axis of the redirecting section 3002 is the same as the axis of the tablet press turret 1. It should be noted that the guide section 3001 and the redirecting section 3002 are smoothly connected. When the tablet core moves to the top of the middle die hole, the telescopic shaft pin 20 just enters the redirecting section 3002. After entering the redirecting section 3002, the inner side wall of the guide groove 30 guides the telescopic shaft pin 20 to move with the axis of the tablet press turret 1 as the axis. The movement trajectory 32 of the tablet core is the same as the movement trajectory 31 of the middle die hole directly below it, and the tablet core is always directly above the corresponding middle die hole.

[0065] like Figure 7 and Fig.14 As shown, a plurality of assembly grooves 1101 are arranged in an array on the top surface of the core turret 11, and each assembly groove 1101 is slidably connected to a telescopic shaft pin 20. At the same time, a plurality of assembly cavities 1102 are arranged in an array inside the core turret 11, and an assembly cavity 1102 is provided directly below each assembly groove 1101, and the assembly cavity 1102 is slidably connected to the telescopic shaft 18, wherein a limit spring 21 is provided in the assembly groove 1101, and the left end of the limit spring 21 abuts against the side surface of the assembly groove 1101, and the right end of the limit spring 21 abuts against the outer peripheral side surface of the telescopic shaft pin 20. The elastic force of the limit spring 21 can assist in limiting the telescopic shaft pin 20, thereby eliminating the gap of the radial movement of the telescopic shaft 18 in the assembly cavity 1102 along the core turret 11.

[0066] like Fig. 9 and Fig.11 As shown, in addition, a guide plate 15 is provided on the top surface of the core turret 11, and the guide plate 15 is fixed to the core turret 11 by positioning pins and bolts. A plurality of guide holes 1501 are arranged in an array on the top surface of the guide plate 15, and a guide hole 1501 is provided directly above each assembly groove 1101. The guide hole 1501 is slidably connected to the telescopic shaft pin 20. Specifically, a sliding sleeve 2001 is provided on the outer peripheral side surface of the telescopic shaft pin 20, and the sliding sleeve 2001 is slidably connected to the guide hole 1501. The guide hole 1501 limits the movement direction of the telescopic shaft pin 20, so that the telescopic shaft 18 can only move radially along the core turret 11.

[0067] In one embodiment of the present invention, a guide wheel 19 is rotatably connected to the top end of the telescopic shaft 18, and the outer wall of the guide wheel 19 abuts against one of the side surfaces of the guide groove 30. When the core turret 11 drives the telescopic shaft pin 20 to rotate relative to the guide groove 30, the guide wheel 19 abuts against one of the side surfaces of the guide groove 30, thereby replacing the sliding friction between the telescopic shaft pin 20 and the guide groove 30 with rolling friction, making the cooperation between the telescopic shaft pin 20 and the guide groove 30 smoother, and can effectively reduce the friction loss between the telescopic shaft pin 20 and the guide groove 30, thereby extending the service life of the overall core distribution device 4.

[0068] It should be noted that the planar cam 14 is generally ring-shaped, and a cross-roller bearing 29 is provided on the inner side of the planar cam 14. The inner wall of the planar cam 14 abuts against the outer wall of the cross-roller bearing 29, and the inner wall of the cross-roller bearing 29 abuts against the outer wall of the shaft core 13. The setting of the cross-roller bearing 29 avoids rotational friction between the planar cam 14 and the shaft core 13, makes the planar cam 14 and the shaft core 13 cooperate more smoothly, and further improves the service life of the overall core distribution device 4.

[0069] The chip package production method adopted by the present invention specifically includes the following steps: during the operation of the tablet press, the driving device drives the tablet press turret 1 to rotate, and the first gear 2, the second gear 3 and the gear group are meshed with each other to drive the shaft core 13 to rotate, and the shaft core 13 drives the tablet core turret 11 to rotate synchronously, and the tablet core is transported by the transmission belt, and the tablet core enters the tablet core turret 11 through the gap on the distribution plate track ring 7, and is hooked by the hook-shaped structure on the tablet core mold 16, and the tablet core mold 16 drives the tablet core to rotate on the fixed base plate 6, and the tablet core mold 16 drives the tablet core to leave the fixed base plate Before the plate 6 moves to the tablet press turret 1, the core mold 16 is close to the core clamp 26, and the core clamp 26 cooperates with the core mold 16 to clamp the core. When the core moves to just above the middle mold hole, the change-of-direction section 3002 guides the telescopic shaft pin 20 to move with the axis of the tablet press turret 1 as the axis. The movement trajectory 32 of the core is the same as the movement trajectory 31 of the middle mold hole just below it, and the core is always just above the corresponding middle mold hole. The pressing wheel forces the core pressing block 22 to be pressed down, and the core pressing block 22 drives the core pressing needle 25 to press down to contact the core and press the core into the middle mold hole to complete the filling.

[0070] It should be noted that the rotational speed of the shaft core 13 and the rotational speed of the tablet press turret 1 maintain a preset proportional relationship. Specifically, by setting the transmission ratio between the first gear 2, the second gear 3 and the gear group, the rotational speed of the core turret 11 relative to the tablet press turret 1 is precisely controlled, so that the rotational speed of the shaft core 13 and the rotational speed of the tablet press turret 1 maintain a preset proportional relationship, so that the multiple cores carried by the core mold 16 are concentric with the middle mold holes on the tablet press turret 1 in turn, and the multiple core pressing needles 25 carried by the core mold 16 can always accurately press the cores into the corresponding middle mold holes, so as to ensure the smooth operation of the tablet press turret 1 and the core turret 11.

[0071] In summary, the movement path of the telescopic shaft pin 20 is limited by the redirecting section 3002 in the guide groove 30, so that the telescopic shaft pin 20 moves with the axis of the tablet press turret 1 as the axis. When the tablet core coincides with the horizontal plane of the center of the middle mold hole, the movement trajectory 32 of the tablet core is the same as the movement trajectory 31 of the middle mold hole directly below it. Within a certain period of time, the tablet core is always directly above the corresponding middle mold hole, which effectively prolongs the overlap time of the tablet core and the middle mold hole, allowing the tablet core to have sufficient time to be filled into the middle mold hole, thereby reducing the concentricity deviation of the tablet core and effectively improving the qualified rate of chip packaging production.

[0072] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
