Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, specifically to an industrial robot for inkjet printing on biological reagent bottles. Background Technology

[0002] Biological reagent bottles are indispensable containers in biological experiments, pharmaceutical research and development, and production. The coding of biological reagent bottles is a key link to ensure product traceability, compliance, and safety, especially in the fields of medicine, scientific research, and biotechnology.

[0003] Existing technology 1 (Chinese patent with announcement number CN119872078A and announcement date of 2025-04-25) discloses a multifunctional industrial robot for coding cosmetic bottles, relating to the field of coding technology. It includes a conveying device comprising a gantry frame with a position control structure mounted on it. The position control structure is equipped with a robot execution structure, which includes two arc-shaped plates. A camera and a coding device are mounted on the outer side of one of the arc-shaped plates, while a liquid storage tank and an equipment box are mounted on the outer side of the other arc-shaped plate. A transmission assembly and a diversion box are provided between the liquid storage tank and the equipment box. A clamping structure drives the bottle to be processed to rotate. When a human-machine interface detects impurities or dust on the bottle that could affect the coding quality, the robot execution structure cleans the dust and impurities from the bottle and then dries it, preventing accidental adhesion of dust and impurities during transport from affecting the coding quality.

[0004] There is also existing technology two (Chinese patent with announcement number CN120481454A and announcement date of 2025-08-15) for an industrial robot for coding cosmetic bottles, including a support frame and a fixed base. The upper side of the inner cavity of the support frame is rotatably mounted with a transmission belt via a rotating roller. The inner surface of the connecting base is fixedly mounted with a coding machine and a first camera and a second camera. A dust guide cover is fixedly mounted on the periphery of the fixed base. Multiple cleaning brushes are rotatably mounted between the fixed base and the dust guide cover. A dust collection box is fixedly mounted on the outer side of the lower end of a transverse pneumatic push rod. The dust guide cover and the dust collection box are connected and communicate with each other through a conduit. An air outlet is opened at the upper end of the dust collection box. A second motor is fixedly mounted inside the air outlet. A fan blade is fixedly mounted on the lower end of the second motor through its output shaft. By using the industrial robot for coding cosmetic bottles, the dust guide cover and dust collection box can absorb dust during dust cleaning, preventing dust from re-adhering to cosmetics.

[0005] While existing technologies can clean the bottles to be processed to prevent dust from interfering with the coding operation, they cannot limit the movement of the bottles during processing. The shaking of the bottles during coding will affect the coding effect. In addition, the coding drying efficiency is low after coding is completed, and the coding is prone to blurring.

[0006] Therefore, we propose an industrial robot for inkjet printing on biological reagent bottles to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an industrial robot for inkjet printing on biological reagent bottles, in order to solve the problems mentioned in the background art, such as the inability to limit the bottle body during processing, the shaking of the bottle body affecting the inkjet printing effect during inkjet printing, and the low drying efficiency and easy blurring of the inkjet printing after inkjet printing.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an industrial robot for coding biological reagent bottles, comprising a fixed frame, a conveyor plate for conveying the bottle body is fixedly connected to the fixed frame, a transverse moving seat is fixedly connected to the upper side of the fixed frame, a vertical moving seat is provided on the transverse moving seat, and an inkjet cartridge for coding is provided on the vertical moving seat. A placement box for placing the bottle body is provided on the conveyor plate. A toothed plate is rotatably connected inside the placement box, and a limiting cylinder is fixedly connected to the upper surface of the toothed plate. A stabilizing mechanism is provided inside the limiting cylinder. The stabilizing mechanism achieves stable placement of the bottle body through the placing force of the bottle body and the movement of the contact plate contained therein. An air jet mechanism is also provided inside the placement box. The air jet mechanism achieves the drying treatment of the inkjet through the expansion of the auxiliary airbag contained therein.

[0009] Preferably, a sliding rod is slidably connected to the limiting cylinder, and the inner end of the sliding rod is fixedly connected to the contact plate, and a spring is fixedly connected between the contact plate and the inner wall of the limiting cylinder.

[0010] Preferably, the stabilizing mechanism includes an auxiliary box, which is fixedly connected to the upper surface of the gear and located at the center of the limiting cylinder. A connecting rod is slidably connected to the upper surface of the auxiliary box, and a fixing plate is fixedly connected to the upper end of the connecting rod. The upper surface of the fixing plate is arranged in a circular array with suction cups to enhance the stability of the bottle placement.

[0011] Preferably, the lower end of the connecting rod is fixedly connected to an abutment block, and the inner side of the abutment block is provided with an abutment groove, which is arranged in an inclined structure.

[0012] Preferably, an auxiliary rod is slidably connected inside the contact groove, and a linkage rod is fixedly connected to the outside of the auxiliary rod. The linkage rod is slidably connected to the limiting cylinder and the auxiliary box. The outer end of the linkage rod is fixedly connected to the outer end of the slide rod. When the linkage rod slides outward, the contact block moves upward under the action of the auxiliary rod.

[0013] Preferably, a telescopic rod is fixedly connected to the outside of the placement box, and a toothed plate is fixedly connected to the output end of the telescopic rod. The toothed plate is slidably disposed on the placement box, and the toothed plate meshes with the gear.

[0014] Preferably, the placement box has a limiting groove inside, and a limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the side of the toothed plate.

[0015] Preferably, the jetting mechanism includes a first pressure plate, which is fixedly connected to the outside of the limiting cylinder, and a second pressure plate is also fixedly connected to the outside of the limiting cylinder, with the second pressure plate located below the first pressure plate. The side wall of the placement box is fixedly connected to a first airbag and a second airbag.

[0016] Preferably, a fixing block is fixedly connected to the upper side of the placement box, and a limiting ball is rotatably connected to the fixing block. A nozzle is fixedly connected to the limiting ball facing the inside of the placement box. A connecting hose is provided between the nozzle and the first airbag. An auxiliary airbag is fixedly connected to the side of the fixing block, and a connecting hose is provided between the auxiliary airbag and the second airbag. A swing rod is fixedly connected to the limiting ball facing the outside of the placement box, and the side of the swing rod is fixedly connected to the auxiliary airbag.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Bottles to be printed are placed sequentially into the limiting cylinder of the placement box. The conveyor plate is started to move the placement box. When the placement box reaches directly below the inkjet cartridge, the horizontal and vertical moving seats are triggered to drive the inkjet cartridge to complete the positioning and printing of each bottle. After printing is completed, the conveyor plate continues to move to the next station, realizing fully automated operation, significantly improving printing efficiency and reducing manual intervention.

[0018] When the bottle is placed inside the limiting cylinder, it first contacts the contact plate, applies force to it to move it to the side of the limiting cylinder and squeeze the spring, causing the spring to undergo elastic deformation. According to Hooke's Law, the spring applies a reverse elastic force to the contact plate, which is transmitted through the contact plate to form a reaction force on the bottle, achieving initial clamping and limiting, ensuring the stability of the bottle placement and the accuracy of subsequent coding.

[0019] When the contact plate moves outward due to the contact with the bottle, it simultaneously drives the slide rod to move stably outward along the limiting cylinder. The outward-moving slide rod pulls the linkage rod, causing the contact block to move upward, which in turn causes the fixed plate to move upward, thus making the suction cup in close contact with the bottle. The suction cup's adsorption effect improves the stability of the bottle placement, ensuring the normal operation of subsequent coding. It effectively reduces the displacement of the bottle caused by vibration, shaking, and other factors during subsequent coding operations, ensuring that the coding operation can be carried out accurately and stably, improving coding quality and production efficiency.

[0020] After the coding operation is completed, the telescopic rod is activated simultaneously, which moves the toothed plate. The toothed plate drives the meshing gears and the limiting cylinder to rotate, turning the coding side of the bottle towards the nozzle side. At the same time, the first pressure plate at the outer end of the limiting cylinder rotates and squeezes the first airbag. The gas inside is sprayed out from the nozzle through the connecting hose and acts on the coding area of ​​the bottle. This can quickly remove the moisture from the coding surface, accelerate the drying process of the coding, and effectively avoid blurring during handling due to incomplete coding, ensuring the quality and clarity of the coding.

[0021] During rotation, the limiting cylinder synchronously drives the second pressure plate to rotate, which in turn compresses the second airbag. At this time, the auxiliary airbag expands, and the expanded auxiliary airbag comes into contact with the swing rod and applies a thrust to it, pushing the swing rod to move. Under the action of the force, the swing rod drives the limiting ball to rotate, and the rotation of the limiting ball will further drive the nozzle to swing. Through the swing of the nozzle, the spray range can be effectively expanded, thereby ensuring that the inkjet code on the bottle can be completely dried. Attached Figure Description

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] Example 1: To improve work efficiency, a conveyor plate 2 is installed. The bottles to be processed are conveyed via the conveyor plate 2, saving manpower, such as... Figure 1 and Figure 2 The present invention provides the following technical solution: an industrial robot for coding biological reagent bottles, wherein a conveyor plate 2 for conveying the bottle is fixedly connected to a fixed frame 1, a horizontal moving seat 4 is fixedly connected to the upper side of the fixed frame 1, a vertical moving seat 5 is provided on the horizontal moving seat 4, and an inkjet cartridge 6 for coding is provided on the vertical moving seat 5. A sliding rod 19 is slidably connected to a limiting cylinder 8, and the inner end of the sliding rod 19 is fixedly connected to a contact plate 15. A spring 20 is fixedly connected between the contact plate 15 and the inner wall of the limiting cylinder 8.

[0026] Bottles to be marked are placed one by one into the limiting cylinder 8 on the placement box 3. After placement, the conveyor plate 2 is started. The conveyor plate 2 will smoothly transport the placement box 3 according to the preset program. When the placement box 3 is transported to the precise position corresponding to the inkjet cartridge 6, the horizontal moving seat 4 and the vertical moving seat 5 are started simultaneously. The horizontal moving seat 4 and the vertical moving seat 5 cooperate with each other according to the predetermined motion logic, driving the inkjet cartridge 6 to accurately mark the bottles placed in the limiting cylinder 8 one by one. After the bottle marking operation is completed, the conveyor plate 2 continues to drive the placement box 3 to move continuously, and so on to carry out subsequent marking operations, thereby significantly improving the marking efficiency of the bottles and effectively saving manpower and time costs.

[0027] Example 2: To ensure the stability of the bottle during the coding process and to avoid blurry coding due to bottle shaking, such as... Figure 3-Figure 7 The present invention provides the following technical solution: an industrial robot for coding biological reagent bottles, wherein a placement box 3 for placing bottles is provided on a conveyor plate 2, a toothed plate 10 is rotatably connected inside the placement box 3, and a limiting cylinder 8 is fixedly connected to the upper surface of the toothed plate 10, and a stabilizing mechanism is provided inside the limiting cylinder 8. The stabilizing mechanism achieves stable placement of the bottle by the placement force of the bottle and the movement of the abutment plate 15 contained therein. The stabilizing mechanism includes an auxiliary box 18, which is fixedly connected to the upper surface of the gear 9 and located at the center of the limiting cylinder 8, and a connecting rod is slidably connected to the upper surface of the auxiliary box 18. 26. At the same time, a fixed plate 17 is fixedly connected to the upper end of the connecting rod 26, and suction cups 16 for enhancing the stability of the bottle are distributed in a ring array on the upper surface of the fixed plate 17. A contact block 24 is fixedly connected to the lower end of the connecting rod 26, and a contact groove 25 is opened on the inner side of the contact block 24. The contact groove 25 is set in an inclined structure. An auxiliary rod 23 is slidably connected inside the contact groove 25, and a linkage rod 22 is fixedly connected to the outer side of the auxiliary rod 23. The linkage rod 22 is slidably connected to the limiting cylinder 8 and the auxiliary box 18. The outer end of the linkage rod 22 is fixedly connected to the outer end of the slide rod 19. When the linkage rod 22 slides outward, the contact block 24 moves upward under the action of the auxiliary rod 23.

[0028] When the bottle is placed inside the limiting cylinder 8, the bottle first comes into contact with the pre-set contact plate 15 inside the limiting cylinder 8. The bottle then applies a force to the contact plate 15, causing the contact plate 15 to move closer to the side of the limiting cylinder 8. During this movement, the contact plate 15 compresses the spring 20 connected to it, causing the spring 20 to undergo elastic deformation in accordance with the laws of elasticity. After the bottle is fully placed in position, the elastically deformed spring 20 applies an elastic force to the contact plate 15 in the opposite direction of deformation. This elastic force is transmitted to the bottle through the contact plate 15, causing the contact plate 15 to apply a reaction force to the bottle, thereby achieving the initial clamping and limiting of the bottle. This initial clamping and limiting mechanism can effectively ensure the stability of the bottle placed inside the limiting cylinder 8, providing a reliable guarantee for the accuracy of subsequent coding operations.

[0029] As the contact plate 15 moves outward under the pressure of the bottle itself, it drives the slide rod 19 to move stably outward along the limiting cylinder 8. When the slide rod 19 moves, it applies a pulling force to the linkage rod 22, causing the linkage rod 22 to move outward synchronously under the pulling force. An auxiliary rod 23 is provided at the inner end of the linkage rod 22. The auxiliary rod 23 cooperates with the contact groove 25 on the contact block 24. Since the contact groove 25 adopts an inclined structure design, when the auxiliary rod 23 slides along the contact groove 25, according to... Based on the principle of inclined plane mechanics, the auxiliary rod 23 will push the contact block 24 to move upward. Driven by the upward movement of the contact block 24, the fixed plate 17 will also move upward. The fixed plate 17 is equipped with a suction cup 16. When the fixed plate 17 moves the suction cup 16 upward and makes close contact with the bottle, the suction cup 16 will deform under its own elasticity, expelling the air between the suction cup 16 and the bottle, forming a negative pressure environment, thereby generating a strong adsorption force, further improving the stability of the bottle placed in the limiting cylinder 8.

[0030] Example 3: To avoid blurring due to incomplete drying of the inkjet printing, an air jet mechanism is installed to further improve the drying efficiency of the inkjet printing, such as... Figures 8-10 The present invention provides the following technical solution: an industrial robot for inkjet printing on biological reagent bottles, which is disclosed. The placement box 3 is equipped with an air jet mechanism, which dries the inkjet ink through the expansion of its auxiliary airbag 21. A telescopic rod 7 is fixedly connected to the outside of the placement box 3, and a toothed plate 10 is fixedly connected to the output end of the telescopic rod 7. The toothed plate 10 is slidably disposed on the placement box 3, and meshes with the gear 9. A limiting groove 12 is formed inside the placement box 3, and a limiting block 11 is slidably connected inside the limiting groove 12. The limiting block 11 is fixedly connected to the side of the toothed plate 10. The air jet mechanism includes a first pressure plate 27, which is fixedly connected to the outside of the limiting cylinder 8. A second pressure plate 2 is also fixedly connected to the outside of the limiting cylinder 8. 8. The second pressure plate 28 is located below the first pressure plate 27. The side wall of the placement box 3 is fixedly connected to the first airbag 29 and the second airbag 30. The upper side of the side of the placement box 3 is fixedly connected to the fixing block 13, and the fixing block 13 is rotatably connected to the limiting ball 32. The limiting ball 32 is fixedly connected to the nozzle 14 facing the inside of the placement box 3. A connecting hose 31 is provided between the nozzle 14 and the first airbag 29. The side of the fixing block 13 is fixedly connected to the auxiliary airbag 21, and the auxiliary airbag 21 is provided to the second airbag 30. The limiting ball 32 is fixedly connected to the swing rod 33 facing the outside of the placement box 3, and the side of the swing rod 33 is fixedly connected to the auxiliary airbag 21.

[0031] After the coding operation is successfully completed, the control system synchronously activates the telescopic rod 7. Driven by power, the telescopic rod 7 moves the toothed plate 10 connected to it. During the movement of the toothed plate 10, the limiting blocks 11 on its sides slide within the limiting grooves 12, ensuring that the toothed plate 10 can only move stably along a specific straight line, avoiding deviation and wobbling. The linear movement of the toothed plate 10 drives the gear 9 meshing with it to rotate. The rotation of the gear 9 is transmitted synchronously to the limiting cylinder 8 through its fixed connection with the shaft, thereby causing the limiting cylinder 8 to rotate around its own axis. The rotation of the limiting cylinder 8... The coding side of the bottle placed inside is precisely turned to the nozzle 14 side to prepare for the subsequent drying process. When the limiting cylinder 8 rotates, the first pressure plate 27 fixedly connected to its outer end will also rotate synchronously. During the rotation, the first pressure plate 27 will gradually approach and squeeze the first air bag 29. Under the squeezing action of the first pressure plate 27, the first air bag 29 will undergo elastic deformation, the gas stored inside will be compressed, and the pressure will increase. The gas inside the first air bag 29 will be transported to the nozzle 14 through the connecting hose 31. The gas will be sprayed out from the nozzle 14 to accelerate the drying of the coding on the bottle.

[0032] When the limiting cylinder 8 is rotating, it synchronously drives the second pressure plate 28 to rotate in the circumferential direction. During the rotation, the contact surface between the second pressure plate 28 and the second airbag 30 will gradually apply pressure, causing the second airbag 30 to undergo elastic deformation. After the second pressure plate 28 squeezes the second airbag 30, the gas inside the second airbag 30 will flow to the auxiliary airbag 21 through the connecting hose 31. After the gas enters the auxiliary airbag 21, the volume of the auxiliary airbag 21 will gradually expand. The expanded auxiliary airbag 21 will contact one end of the swing rod 33 and apply a lateral thrust to it. Under the action of the thrust of the auxiliary airbag 21, the swing rod 33 will swing around the limiting ball 32. The rotation of the limiting ball 32 can be directly transmitted to the nozzle 14, causing the nozzle 14 to swing, thereby expanding the spray range and ensuring that the code is blown by a uniform airflow in a short time, achieving complete drying. This effectively avoids quality problems such as blurring and falling off during subsequent handling due to incomplete drying of the code.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
