[0012] As a further solution of the present invention, the ear plate is adapted to the size of the opening, and the angle between the opening and the anti-rotation groove is ninety degrees.

[0013] A method for using an automatic coding robot for drug packaging, the method comprising the following steps:

[0014] When the coding work is performed on the medicine packaging box, the coding mechanism is installed on the limit assembly at the bottom of the adjustment arm, and the robot body is controlled to work so that its mechanical arm drives the coding mechanism to adjust. When the nozzle at the bottom of the coding mechanism is adjusted to the coding area, the coding mechanism and the robot body work synchronously to achieve the purpose of coding the medicine packaging box. After the coding work is completed, the mechanical arm on the robot body drives the adjustment arm and the coding mechanism back to the initial position;

[0015] When removing the inkjet printer from the adjusting arm, hold the two handles and pull them to both sides, so that the two handles respectively drive the two clamping blocks away from each other, so that the clamping blocks are out of the locked state between the clamping slots, and then lift the two handles to drive the inkjet printer downward, so that the limit frame at the bottom of the mounting plate is out of the limit slot, and the inkjet printer can be separated from the adjusting arm, completing the disassembly of the inkjet printer;

[0016] When installing the inkjet mechanism on the mounting plate, hold the two handles to lift the inkjet mechanism so that the limit groove corresponds to the limit frame at the bottom of the mounting plate, and limit the limit frame through the limit groove to improve the installation stability of the inkjet mechanism. In the process of moving the inkjet mechanism upward, the two clamping blocks are in contact with the bottom of the mounting plate. Because the top of the clamping block is designed as an inclined surface, the two clamping blocks can move away from each other and squeeze the first spring after being pressed until the limit frame is completely inserted into the limit groove. At the same time, the clamping block moves into the inside of the clamping slot, and the elastic force of the first spring supports the clamping block so that the clamping block can be embedded in the L-shaped clamping slot, thereby achieving the purpose of locking the clamping block, that is, completing the installation of the inkjet mechanism.

[0017] When the nozzle is removed from the bottom of the inkjet printing mechanism for clearing the blockage, hold the nozzle and move it upward, so that the nozzle drives the two ear plates to move upward, so that the ear plates drive the clamping column to disengage from the anti-rotation groove inside the clamping sleeve, and the ear plates can push the pressure ring upward during the upward movement, so that the pressure ring drives the telescopic rod to contract and squeeze the second spring, and after releasing the locking state between the clamping column and the anti-rotation groove, rotate the nozzle so that the nozzle drives the clamping column to rotate through the ear plates, and the clamping column is located directly above the opening after rotating ninety degrees. Because the ear plates are adapted to the size of the opening, stop rotating the nozzle, pull the nozzle downward to drive the ear plates and the clamping column to move downward, and cooperate with the elastic force of the second spring to support the pressure ring, so that the pressure ring can squeeze the ear plates to assist the ear plates to disengage from the opening, so that the nozzle is completely separated from the clamping sleeve, that is, the nozzle is removed from the inkjet printing mechanism, so as to facilitate unblocking the nozzle;

[0018] After the nozzle is unblocked and installed in the ferrule, hold the nozzle and align the two external ear plates with the two openings below the ferrule, move the nozzle upward so that the ear plates and the clamping column pass through the openings, and the two ear plates will push the pressure ring upward to drive the telescopic rod to contract and squeeze the second spring. When the clamping column completely enters the interior of the ferrule, rotate the nozzle ninety degrees to drive the ear plates and the clamping column to rotate. When the clamping column rotates to the position of the anti-rotation groove, the pressure ring is supported by the elastic force of the second spring, so that the telescopic rod drives the pressure ring to push down the ear plates, and the ear plates drive the clamping column to fit into the anti-rotation groove, thereby achieving the purpose of locking the nozzle position. At this time, the top end of the nozzle passes through the connecting seat and extends into the interior of the inkjet mechanism, and the outer wall of the nozzle fits with the inner wall of the sealing ring, thereby achieving the purpose of sealing the nozzle installation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the nozzle is removed from the bottom of the inkjet printing mechanism for clearing, the present invention holds the nozzle and moves it upward, so that the nozzle drives the two ear plates to move upward, so that the ear plates drive the clamping column to disengage from the anti-rotation groove inside the clamping sleeve, and after releasing the locking state between the clamping column and the anti-rotation groove, the nozzle is rotated, so that the nozzle drives the clamping column to rotate through the ear plates, and the clamping column is located directly above the opening after rotating ninety degrees. Since the ear plates are adapted to the size of the opening, the rotation of the nozzle is stopped, and the nozzle is pulled downward to drive the ear plates and the clamping column to move downward, and the elastic force of the second spring supports the pressing ring, so that the pressing ring can squeeze the ear plates to assist the ear plates to disengage from the opening, so that the nozzle is completely disengaged from the clamping sleeve, that is, the nozzle is removed from the inkjet printing mechanism. When installing the nozzle, the two ear plates are aligned with the bottom of the clamping sleeve. Two openings, move the nozzle upward to make the ear plate and the clamping column pass through the opening, the two ear plates will push the pressure ring upward, so that the pressure ring drives the telescopic rod to contract and squeeze the second spring, and when the clamping column completely enters the interior of the clamping sleeve, rotate the nozzle ninety degrees, so that the nozzle drives the ear plate and the clamping column to rotate. When the clamping column rotates to the position of the anti-rotation groove, the pressure ring is supported by the elastic force of the second spring, so that the telescopic rod drives the pressure ring to push the ear plate downward, and the ear plate drives the clamping column to be stuck in the anti-rotation groove, so as to achieve the purpose of locking the nozzle position, thereby abandoning the inkjet printer with an integrated design of the nozzle and the inkjet mechanism, and achieving the purpose of quickly disassembling and replacing the nozzle, which is convenient for unblocking the nozzle, reducing the workload, preventing the nozzle from being blocked and affecting the inkjet work, and is conducive to the efficient and stable inkjet operation of the medicine box.

[0021] 2. When removing the inkjet mechanism from the adjusting arm, the present invention holds the two handles and pulls them toward both sides, so that the two handles respectively drive the two blocks away from each other, so that the blocks are released from the locked state between the card slots, and then lifts the two handles to drive the inkjet mechanism downward, so that the limit frame at the bottom of the mounting plate is released from the limit slot, so that the inkjet mechanism can be separated from the adjusting arm, and the disassembly of the inkjet mechanism is completed, thereby improving the convenience of operation. When installing the inkjet mechanism, the two handles are held to lift the inkjet mechanism, so that the limit slot corresponds to the limit frame at the bottom of the mounting plate, and the limit frame is limited by the limit slot, thereby improving the inkjet mechanism. Installation stability: during the upward movement of the inkjet printing mechanism, the two blocks are in contact with the bottom of the mounting plate. Because the top of the block is designed as an inclined surface, the two blocks can move away from each other and squeeze the first spring after being pressed until the limit frame is completely inserted into the limit groove. At the same time, the block moves into the groove and is supported by the elastic force of the first spring, so that the block can be embedded in the L-shaped groove. The installation of the inkjet printing mechanism is completed, and the traditional method of installing the inkjet printing mechanism on the robot arm with bolts is abandoned, which improves the convenience of operation and facilitates daily maintenance or replacement of the inkjet printing mechanism.

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.

[0037] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0038] An automatic coding robot for drug packaging includes a base 1, a robot body 2 is mounted on the base 1, an adjusting arm 3 is mounted on the mechanical arm of the robot body 2, a limiting assembly 4 is mounted on the bottom end of the adjusting arm 3, and a coding mechanism 6 is mounted on the bottom of the limiting assembly 4. Specifically, a limiting groove 5 is provided on the coding mechanism 6, and the bottom of the limiting assembly 4 is embedded in the limiting groove 5. The limiting assembly 4 includes a mounting plate 401, which is fixed to the bottom of the adjusting arm 3, and a clamping groove 402 is respectively provided on both sides of the bottom of the mounting plate 401, and the clamping groove 402 is L-shaped. The bottom of the mounting plate 401 is fixedly connected to a limiting frame 403, and the limiting frame 403 is clamped in the limiting groove 5, and the limiting groove 5 is rectangular. The limiting groove 5 at the bottom of the coding mechanism 6 corresponds to the limiting frame 403 at the bottom of the mounting plate 401, and the limiting frame 403 is limited by the limiting groove 5, so as to improve the installation stability of the coding mechanism 6.

[0039] As a further solution of the present invention, the locking assembly 10 is clamped in the card slot 402, and the locking assembly 10 includes a card block 101, which is clamped in the card slot 402.

The outer sleeve of the slide bar 102 is connected with a first spring 103, and the two ends of the first spring 103 are respectively fixed on one side of the card block 101 and the inner wall of the groove 9. The outer side of the card block 101 is fixedly connected with a handle 104, and the handle 104 is located outside the coding mechanism 6. A slide groove 11 is opened on one side of the inner wall of the groove 9, and a blocking bar 105 is slidably connected in the slide groove 11, and the blocking bar 105 is fixed on one side of the card block 101.

[0040] By holding the two handles 104 and pulling them toward both sides, the two handles 104 respectively drive the two blocks 101 to move away from each other. Since the block 101 can slide outside the slide rod 102, it plays a role of supporting and limiting the block 101, thereby improving the stability of the horizontal movement of the block 101; the block 101 is supported by the elastic force of the first spring 103, so that the block 101 can be embedded in the L-shaped slot 402, and the slot 402 limits the block 101 to prevent the block 101 from escaping from the slot 402.

[0041] During the movement of the card block 101, the blocking bar 105 can be driven to slide in the slide groove 11. The blocking bar 105 is limited by the slide groove 11, which can support the card block 101 and prevent the card block 101 from shifting position and affecting the stability of the card connection. In addition, the blocking bar 105 can shield the slide rod 102 and the first spring 103 to prevent dust and water stains from entering and affecting the performance of the first spring 103.

[0043] The sealing assembly 13 includes a baffle frame 131, which is fixed above the inner wall of the ferrule 12. A plurality of fixing columns 132 are fixed to the top of the baffle frame 131. The top ends of the fixing columns 132 are fixed to the top of the inner wall of the ferrule 12. A sealing ring 133 is provided in the baffle frame 131. The cross-sectional shape of the sealing ring 133 is L-shaped. The outer wall of the nozzle 8 overlaps the inner wall of the sealing ring 133.

[0044] The top end of the nozzle 8 passes through the connecting seat 7 and extends into the interior of the coding mechanism 6, and the outer wall of the nozzle 8 fits with the inner wall of the sealing ring 133 to achieve the purpose of sealing the nozzle 8 and prevent leakage at the connection between the nozzle 8 and the coding mechanism 6.

[0045] The inner wall of the ferrule 12 is fixedly connected with a partition 14, the bottom of the partition 14 is fixedly connected with a support assembly 15, the bottom of the support assembly 15 is overlapped with two ear plates 18, the bottom of the ear plate 18 is fixedly connected with a clamping column 19, the two sides of the bottom of the ferrule 12 are respectively provided with openings 16, and the bottom of the inner wall of the ferrule 12 is provided with two anti-rotation grooves 17, and the clamping column 19 is clamped in the anti-rotation groove 17. The ear plate 18 drives the clamping column 19 to be clamped into the anti-rotation groove 17, so as to achieve the purpose of locking the position of the nozzle 8, thereby abandoning the inkjet printer with an integrated design of the nozzle 8 and the inkjet mechanism 6, and achieving the purpose of quickly dismantling and replacing the nozzle 8, thereby facilitating the dredging of the nozzle 8 and reducing the workload.

[0046] As a further solution of the present invention, the support assembly 15 includes a pressure ring 151, the bottom of the pressure ring 151 is overlapped with the two ear plates 18, the top of the pressure ring 151 is fixedly connected to a plurality of telescopic rods 152, the top of the telescopic rod 152 is fixed to the bottom of the partition 14, and the outer sleeve of the telescopic rod 152 is connected with a second spring 153, and the two ends of the second spring 153 are respectively fixed between the partition 14 and the pressure ring 151.

[0047] When the clamping column 19 rotates to the position of the anti-rotation groove 17, the elastic force of the second spring 153 supports the pressing ring 151, so that the telescopic rod 152 drives the pressing ring 151 to push down the ear plate 18, and the ear plate 18 drives the clamping column 19 to be clamped into the anti-rotation groove 17, so as to lock the position of the nozzle 8.

[0048] As a further solution of the present invention, the ear plate 18 is adapted to the size of the opening 16, and the angle between the opening 16 and the anti-rotation groove 17 is ninety degrees.

[0049] After the clamping column 19 is rotated ninety degrees, it is located directly above the opening 16. Since the ear plate 18 is matched in size with the opening 16, the rotation of the nozzle 8 is stopped and the nozzle 8 is pulled downward to drive the ear plate 18 and the clamping column 19 to move downward. The elastic force of the second spring 153 supports the pressing ring 151, so that the pressing ring 151 can squeeze the ear plate 18 to assist the ear plate 18 to detach from the opening 16, so as to facilitate the removal of the nozzle 8.

[0050] A method for using an automatic coding robot for drug packaging, the method comprising the following steps:

[0051] When the coding work is performed on the drug packaging box, the coding mechanism 6 is installed on the limit assembly 4 at the bottom of the adjusting arm 3, and the robot body 2 is controlled to work so that its mechanical arm drives the coding mechanism 6 to adjust. When the nozzle 8 at the bottom of the coding mechanism 6 is adjusted to the coding area, the coding mechanism 6 and the robot body 2 work synchronously to achieve the purpose of coding the drug packaging box. After the coding work is completed, the mechanical arm on the robot body 2 drives the adjusting arm 3 and the coding mechanism 6 back to the initial position;

In the process of moving the inkjet mechanism 6 upward, the two clamping blocks 101 are in contact with the bottom of the mounting plate 401. Because the top of the clamping block 101 is designed as an inclined surface, the two clamping blocks 101 can move away from each other and squeeze the first spring 103 after being pressed, until the limiting frame 403 is completely stuck in the limiting groove 5, and at the same time, the clamping block 101 moves to the inside of the clamping groove 402, and the clamping block 101 is supported by the elastic force of the first spring 103, so that the clamping block 101 can be embedded in the L-shaped clamping groove 402, so as to achieve the purpose of locking the clamping block 101, that is, to complete the installation of the inkjet mechanism 6;

[0054] When the nozzle 8 is removed from the bottom of the inkjet printing mechanism 6 for clearing, the nozzle 8 is held and moved upward, so that the nozzle 8 drives the two ear plates 18 to move upward, so that the ear plates 18 drive the clamping column 19 to disengage from the anti-rotation groove 17 inside the clamping sleeve 12. During the upward movement of the ear plates 18, the pressure ring 151 can be pushed upward, so that the pressure ring 151 drives the telescopic rod 152 to contract and squeeze the second spring 153. After releasing the locking state between the clamping column 19 and the anti-rotation groove 17, the nozzle 8 is rotated so that the nozzle 8 drives the clamping column through the ear plates 18. 19 rotates, and the clamping column 19 is located above the opening 16 after rotating 90 degrees. Since the size of the ear plate 18 is adapted to the size of the opening 16, the rotation of the nozzle 8 is stopped, and the nozzle 8 is pulled downward to drive the ear plate 18 and the clamping column 19 to move downward, and the elastic force of the second spring 153 supports the pressing ring 151, so that the pressing ring 151 can squeeze the ear plate 18 to assist the ear plate 18 to separate from the opening 16, so that the nozzle 8 is completely separated from the clamping sleeve 12, that is, the nozzle 8 is removed from the coding mechanism 6, so as to facilitate the unblocking of the nozzle 8;

[0055] After the nozzle 8 is unblocked, it is installed in the ferrule 12. The nozzle 8 is held to align the two outer ear plates 18 with the two openings 16 below the ferrule 12. The nozzle 8 is moved upward to allow the ear plates 18 and the clamping column 19 to pass through the openings 16. The two ear plates 18 push the pressing ring 151 upward, so that the pressing ring 151 drives the telescopic rod 152 to contract and squeeze the second spring 153. When the clamping column 19 completely enters the interior of the ferrule 12, the nozzle 8 is rotated 90 degrees, so that the nozzle 8 drives the ear plates 18 and the clamping column 19 to move upward. 9 rotates, when the clamping column 19 rotates to the position of the anti-rotation groove 17, the elastic force of the second spring 153 supports the pressing ring 151, so that the telescopic rod 152 drives the pressing ring 151 to push down the ear plate 18, and the ear plate 18 drives the clamping column 19 to be stuck in the anti-rotation groove 17, so as to achieve the purpose of locking the position of the nozzle 8. At this time, the top end of the nozzle 8 passes through the connecting seat 7 and extends into the interior of the coding mechanism 6, and the outer wall of the nozzle 8 fits with the inner wall of the sealing ring 133, so as to achieve the purpose of sealing the nozzle 8.

A method for using an automatic coding robot for drug packaging, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: When the coding operation is performed on the medicine packaging box, the coding mechanism (6) is installed on the limit assembly (4) at the bottom of the adjustment arm (3), and the robot body (2) is controlled to work so that its mechanical arm drives the coding mechanism (6) to adjust. When the nozzle (8) at the bottom of the coding mechanism (6) is adjusted to the coding area, the coding mechanism (6) and the robot body (2) work synchronously to achieve the purpose of coding the medicine packaging box. After the coding operation is completed, the mechanical arm on the robot body (2) drives the adjustment arm (3) and the coding mechanism (6) back to the initial position. When removing the coding mechanism (6) from the adjusting arm (3), the two handles (104) are held and pulled toward both sides, so that the two handles (104) respectively drive the two clamping blocks (101) to move away from each other, so that the clamping blocks (101) are released from the locked state with the clamping slot (402), and then the two handles (104) are lifted to drive the coding mechanism (6) to move downward, so that the limiting frame (403) at the bottom of the mounting plate (401) is released from the limiting slot (5), so that the coding mechanism (6) can be separated from the adjusting arm (3), and the disassembly of the coding mechanism (6) is completed; When installing the coding mechanism (6) on the mounting plate (401), the two handles (104) are held to lift the coding mechanism (6) so that the limiting groove (5) corresponds to the limiting frame (403) at the bottom of the mounting plate (401). The limiting groove (5) is used to limit the limiting frame (403) to improve the installation stability of the coding mechanism (6). In the process of the coding mechanism (6) moving upward, the two clamping blocks (101) are in contact with the bottom of the mounting plate (401). Since the top of the clamping block (101) is designed as an inclined surface, After being pressed, the two clamping blocks (101) can move away from each other and squeeze the first spring (103) until the limiting frame (403) is completely inserted into the limiting groove (5), and at the same time, the clamping block (101) moves into the inside of the clamping groove (402), and the clamping block (101) is supported by the elastic force of the first spring (103), so that the clamping block (101) can be embedded in the L-shaped clamping groove (402), thereby achieving the purpose of locking the clamping block (101), that is, completing the installation of the coding mechanism (6); When the nozzle (8) is removed from the bottom of the inkjet printing mechanism (6) for clearing, the nozzle (8) is held and moved upward, so that the nozzle (8) drives the two ear plates (18) to move upward, so that the ear plates (18) drive the clamping column (19) to disengage from the anti-rotation groove (17) inside the clamping sleeve (12). During the upward movement of the ear plates (18), the pressure ring (151) can be pushed upward, so that the pressure ring (151) drives the telescopic rod (152) to contract and squeeze the second spring (153). After the locking state between the clamping column (19) and the anti-rotation groove (17) is released, the nozzle (8) is rotated so that the nozzle (8) drives the clamping column (19) through the ear plates (18). 19) is rotated, and the clamping column (19) is located directly above the opening (16) after rotating ninety degrees. Since the ear plate (18) is adapted to the size of the opening (16), the rotation of the nozzle (8) is stopped, and the nozzle (8) is pulled downward to drive the ear plate (18) and the clamping column (19) to move downward, and the elastic force of the second spring (153) is used to support the pressure ring (151), so that the pressure ring (151) can squeeze the ear plate (18) to assist the ear plate (18) to separate from the opening (16), so that the nozzle (8) is completely separated from the clamping sleeve (12), that is, the nozzle (8) is removed from the inkjet printing mechanism (6) to facilitate unblocking the nozzle (8); After the nozzle (8) is unblocked, it is installed in the sleeve (12). The nozzle (8) is held so that the two outer ear plates (18) are aligned with the two openings (16) below the sleeve (12). The nozzle (8) is moved upward so that the ear plates (18) and the clamping column (19) pass through the openings (16). The two ear plates (18) push the pressure ring (151) upward, so that the pressure ring (151) drives the telescopic rod (152) to contract and squeeze the second spring (153). When the clamping column (19) completely enters the interior of the sleeve (12), the nozzle (8) is rotated 90 degrees so that the nozzle (8) drives the ear plates (18) and the clamping column (19) to move. The column (19) rotates. When the clamping column (19) rotates to the position of the anti-rotation groove (17), the elastic force of the second spring (153) supports the pressing ring (151), so that the telescopic rod (152) drives the pressing ring (151) to push down the ear plate (18), and the ear plate (18) drives the clamping column (19) to be clamped into the anti-rotation groove (17), thereby achieving the purpose of locking the position of the nozzle (8). At this time, the top end of the nozzle (8) passes through the connecting seat (7) and extends into the interior of the coding mechanism (6), and the outer wall of the nozzle (8) is in contact with the inner wall of the sealing ring (133), thereby achieving the purpose of sealing the nozzle (8).
