Description

Technical Field

[0001] A positioning tool and positioning component for an inclined powder-liquid dual-chamber bag sterilization tray belong to the field of infusion bag sterilization technology. Background Technology

[0002] The powder-liquid dual-chamber bag is a novel infusion product. Traditional infusion bag sterilization trays cannot reliably fix the powder-liquid dual-chamber bags, thus failing to achieve a good sterilization effect. To solve this problem, the applicant filed a Chinese utility model patent (application number 201520869448.7) on November 3, 2015, entitled "A Powder-Liquid Dual-Chamber Bag Sterilization Tray." This design features a horizontally oriented sterilization tray with multiple rows of horizontal bag-fixing surfaces on its surface, where the medicine bags are horizontally positioned. The applicant subsequently filed another Chinese utility model patent (application number 201520949190.1) on November 25, 2015, also entitled "A Powder-Liquid Dual-Chamber Bag Sterilization Tray." This design features a sterilization tray with multiple rows of inclined bag-fixing surfaces on its surface, where the medicine bags are placed at an angle.

[0003] In actual use, the sterilization tray is driven by the tray transfer mechanism and the top tray assembly in the track unit to achieve stepping motion. The robot picks up and puts the medicine bags at fixed positions. Therefore, before the entire production line is put into use, whether it is a flat sterilization tray or an inclined sterilization tray, it is necessary to locate the position of the positioning pin on the fixed surface of the bag (at least the positioning pin on the fixed surface of the first row of bags). Then, the positioning data is written into the PLC by the host computer and stored so that the robot's gripping point or placement point data and the tray position on the tray transfer mechanism can be matched during subsequent normal operation to avoid mechanical collisions and realize the picking and putting of medicine bags.

[0004] The advantage of the aforementioned flat sterilization tray lies in its simpler and more accurate positioning process. During positioning, since the positioning pins of the flat sterilization tray are perpendicular to the running plane of the track unit, only the position of the positioning pins relative to the track unit needs to be marked. In contrast, with the inclined sterilization tray, the positioning pins fixing the medicine bags are higher than the tray surface. Compared to the flat sterilization tray, this is more conducive to the drying of the powder chamber. However, the problem with the inclined sterilization tray is that the initial positioning work is more difficult. This is because the positioning pins of the inclined sterilization tray are perpendicular to the bag fixing surface, and there is an angle between the bag fixing surface and the plane of the track unit. Therefore, during positioning, it is actually necessary to determine the projection position of the positioning pins on the horizontal plane. Different customers have different requirements for the fixed surface of the bag, so the tilt angle or length of the fixed surface of the bag often varies. This further increases the difficulty of positioning the positioning pin of the sterilization tray during the initial tray transfer and makes it more difficult to mark the position of the tray. In subsequent production, the problem of needing to re-position and calibrate often arises due to insufficient positioning accuracy in the early stage or loss of the zero point of the tray transfer mechanism in the later stage, which has a certain impact on the continuity of production and also affects economic benefits. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tilted powder and liquid dual-chamber bag sterilization tray positioning tool and positioning component that determines the projection position of the fixing pin on the fixed surface of the bag body on the horizontal plane through the base, and further realizes the matching of the data of the robot's gripping point or placement point with the plate position coordinates on the plate transfer mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the inclined powder-liquid dual-chamber bag sterilization tray positioning tool is characterized in that: it includes a base, an angle adjustment plate is provided on the side of the base, the angle adjustment plate is adjustable and is used to be the same as the inclination angle of the bag body fixing surface on the surface of the sterilization tray, and an extension plate is provided at the end of the angle adjustment plate for locking with the bag body fixing surface.

[0007] Preferably, the extension plate is vertically positioned at the bottom of the angle adjustment plate.

[0008] Preferably, the angle adjustment plate is hinged to the side of the base.

[0009] Preferably, the bottom of the angle adjustment plate extends to the side of the base, and the fastener passes through the angle adjustment plate into the base.

[0010] Preferably, the fastener is a fastening bolt, and a fixing hole for connecting to the fastening bolt is provided in the base.

[0011] Preferably, an internal thread is provided in the fixing hole for threaded connection with the fastening bolt.

[0012] The positioning component is characterized by comprising a track unit, wherein the inclined powder-liquid dual-chamber bag sterilization tray positioning tool is placed at the edge of the track unit, and a positioning mechanism for positioning the sterilization tray is provided in the track unit.

[0013] Preferably, the positioning mechanism is a baffle cylinder installed inside the track unit, used to block the sterilization tray after the action, with the piston rod of the baffle cylinder pointing vertically upward.

[0014] Preferably, a lifting cylinder for lifting the sterilization tray is also provided in the track unit, with the piston rod of the lifting cylinder pointing vertically upward.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By using this tilting powder-liquid dual-chamber bag sterilization tray positioning tool and positioning components, after adjusting the angle adjustment plate to the same tilt angle as the bag body fixing surface, and after the extension plate is clipped to the top of the bag body fixing surface, the projection position of the fixing pin on the horizontal plane of the bag body fixing surface is determined by the base. This further enables the matching of the data of the robot's gripping point or placement point with the tray position coordinates on the tray transfer mechanism, avoiding the problem of needing to recalibrate the positioning due to insufficient positioning accuracy in the early stage or loss of the zero point of the tray transfer mechanism in the later stage during subsequent production.

Detailed Implementation

[0024] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-8 The present invention will be further described below.

[0025] like Figures 1-4 As shown, a tilting powder-liquid dual-chamber bag sterilization tray positioning tool includes a base 1, which is rectangular in shape. Fixing holes 5, preferably threaded holes, are provided inside the base 1, penetrating its left and right end faces. An angle adjustment plate 2 is provided on the side of the base 1, located on the left or right side of the base 1, and the surface of the angle adjustment plate 2 is in contact with the corresponding end face of the base 1.

[0026] A fastening bolt 4 is provided on the same side of the angle adjustment plate 2. The bottom of the angle adjustment plate 2 extends to the fixing hole 5 on the side of the base 1. The fastening bolt 4 passes through the angle adjustment plate 2 and is screwed into the fixing hole 5, and is threaded into the fixing hole 5. When the fastening bolt 4 is tightened, the angle adjustment plate 2 is fixed to the side of the base 1, thus fixing the relative angle between the angle adjustment plate 2 and the base 1. An extension plate 3 is provided on the top of the angle adjustment plate 2, and the extension plate 3 is perpendicular to the angle adjustment plate 2.

[0027] The specific positioning process and principle are as follows:

[0028] The conveyor roller 10 inside the track unit 11 rotates, driving the sterilization tray 8 to run within the track unit 11, such as... Figure 5 As shown. The track unit 11 is equipped with a baffle cylinder 6 and a lifting cylinder 9. When positioning is required, the piston rod of the baffle cylinder 6 is deflected before the sterilization tray 8 reaches the baffle cylinder 6. At this time, the top of the piston rod of the baffle cylinder 6 is higher than the bottom surface of the sterilization tray 8. When the sterilization tray 8 moves to the baffle cylinder 6, it stops moving. Figure 6 As shown.

[0029] The piston rod of the lifting cylinder 9 outputs, causing the upper part of the sterilization tray 8 to protrude beyond the upper edge of the track unit 11, and then the above... Figures 1-4 The positioning tool 12 shown is placed on the upper edge of the track unit 11 and positioned at the first row of the sterilization tray 8 (closest to the baffle cylinder 6) bag fixing surface 13, and preferably the angle adjustment plate 2 is positioned on the side close to the sterilization tray 8.

[0030] Combination Figure 7 Loosen the fastening bolt 4 to allow the angle adjustment plate 2 to rotate freely. Rotate the angle adjustment plate 2 so that the angle between it and the base 1 is the same as the tilt angle of the bag fixing surface 13 on the sterilization tray 8. At this time, the plate surface of the angle adjustment plate 2 is flush with the long side (the end face of the mounting positioning pin 7) of the bag fixing surface 13. Adjust the front and rear distance of the positioning tool 12 so that the extension plate 3 is stuck at the top of the short side of the bag fixing surface 13. Figure 8After the positioning tool 12 is placed, the end face of the base 1 facing away from the baffle cylinder 6 is the position of the positioning pin 7 projected onto the horizontal plane. The operator inputs this position information into the controller as the position of the plate on the plate transfer mechanism, which is also the position reached by the first row of plates each time, and the coordinate matching point with the robot's initial gripping or placement point. The positioning of the subsequent rows of positioning pins 7 on the sterilization tray 8 can be performed in the above manner, or it can be calculated based on the size of the sterilization tray 8.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
