Description
Technical Field
[0001] This invention belongs to the field of manufacturing technology of medicine tube assembly equipment, specifically a position guiding mechanism for connecting ear medicine tubes. Background Technology
[0002] During the manufacturing of disposable syringes, various springs are required inside the syringe. Due to process requirements, connecting lugs (such as...) are radially arranged on both sides of one end of the syringe's liquid tubing. Figure 6 As shown in the diagram, this is used to achieve a locking function during assembly. During the assembly process, when the liquid tube with connecting ears is assembled into the syringe housing, the longitudinal position of the connecting ears needs to be exactly in the slot that can be opened on the syringe. This means that the orientation of the connecting ears of the liquid tube needs to be specified before the robot arm can grasp the liquid tube. This reduces the robot arm's movements and allows the robot arm to quickly insert the liquid tube into the syringe housing after grasping it, thereby improving production efficiency. However, when the liquid tube is placed in the liquid tube container, it is disordered. In addition, the liquid tube is similar to a cylinder and is easy to roll. Therefore, the orientation of its connecting ears is also disordered. Therefore, the liquid tube needs to be placed according to the preset orientation of the connecting ears before the robot arm can grasp the liquid tube. Currently, there is no machine that can quickly correct the orientation of the connecting ears of the liquid tube. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by designing a connecting ear medication tube positioning guidance mechanism using two parallel horizontal plates driven by two actuators. This mechanism can guide the medication tubes in batches, ensuring that the connecting ears of the medication tubes are positioned according to a preset orientation. This allows the robotic arm to directly grasp the tubes and insert them into the syringe without requiring the robotic arm to perform additional correction of the connecting ear orientation. This solves the problem of the current lack of a machine capable of quickly correcting the orientation of the connecting ears of medication tubes.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An ear medication tube positioning guide mechanism includes a fixed frame with vertically upward side plates on opposite sides of the fixed frame. The side plates on both sides of the fixed frame are parallel to each other. A horizontal plate is connected to each of the opposite surfaces of the side plates on both sides of the fixed frame. The axes of the two horizontal plates are parallel to the upper surfaces of the side plates and the fixed frame. At least one of the two horizontal plates is slidably connected to the side plate it is on, and the sliding direction is parallel to the axis of the horizontal plate. A linear motion drive device is provided on the side plate, which is connected to the horizontal plate. A medication tube holding device is provided on the fixed frame directly below the gap between the two horizontal plates.
[0006] Preferably, each of the two horizontal plates is slidably connected to the side plate to which it is located, and both side plates are provided with the linear motion drive device.
[0007] Preferably, one of the two horizontal plates is slidably connected to the side plate on which it is located, and the linear motion drive device is provided on the side plate that is slidably connected to the horizontal plate. The linear motion drive device is driven by the horizontal plate on the same side plate.
[0008] Preferably, each of the two horizontal plates is slidably connected to its respective side plate. One of the two side plates is provided with a linear motion drive device, which is a cylinder. The cylinder is fixed to the side plate, and the free end of the piston rod of the cylinder is fixedly connected to the horizontal plate on the side plate where the cylinder is located. The piston rod is parallel to the axis of the horizontal plate, and the two horizontal plates are connected by a reverse drive.
[0009] Preferably, the reverse drive includes a belt and two pulleys, the two pulleys being respectively disposed at both ends of the gap formed between the two horizontal plates, the belt being sleeved on the pulleys, and one of the horizontal plates being fixedly connected to each of the two opposite sidewalls of the belt.
[0010] Preferably, the reverse drive consists of two gears. Each of the two horizontal plates has a row of teeth on its opposite surfaces. The teeth are arranged in a formation parallel to the axis of the horizontal plates. The two gears are respectively located at both ends of the gap formed between the two horizontal plates, and each gear meshes with both horizontal plates simultaneously.
[0011] Preferably, the liquid container is a cylindrical body with its opening facing upwards.
[0012] Preferably, the fixing frame is also provided with a photoelectric detection sensor, and each of the cylinders has a light-transmitting hole on its side wall. The sensing surface of the photoelectric detection sensor faces the light-transmitting hole, and the photoelectric detection sensor signal is connected to the linear motion drive device.
[0013] Preferably, it also includes a platform, on which a fixed frame is provided on each of the opposite sides, the two fixed frames are parallel to each other, the platform is mounted on a support frame, and a motor is mounted on the support frame, the output shaft of the motor being fixedly connected to the geometric center of the platform.
[0014] Preferably, the cross-section of the horizontal plate is shaped like the number 7.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. This invention employs two parallel horizontal plates with two driving mechanisms to design a positioning guide mechanism for the connecting ear of the liquid tube. This mechanism can guide the liquid tubes in batches, ensuring that the connecting ear of the liquid tube is positioned according to a preset orientation. This allows the robotic arm to directly grasp the tubes and insert them into the syringe without requiring the robotic arm to perform additional actions to correct the orientation of the connecting ear. This solves the problem of the current lack of a machine capable of quickly correcting the orientation of the connecting ear of the liquid tube.
[0017] 2. The present invention sets the two horizontal plates to be slidably connected to the side plates they are on, and both side plates are provided with the linear movement drive device. This arrangement makes the relative movement between the two horizontal plates faster, thereby making the adjustment of the direction of the connecting ear of the liquid tube more efficient.
[0018] 3. In this invention, the cross-section of the horizontal plate is set to a figure-7 shape, so that during the time from when the direction of the connecting lug of the liquid tube is adjusted to when the liquid tube is fully inserted into the cylinder, the relative surfaces of the two horizontal plates can avoid friction between the liquid tube.

[0027] See Figure 1-7 An ear medicine tube positioning guide mechanism includes a fixing frame 1. Vertically upward-facing side plates 2 are provided on opposite sides of the fixing frame 1. The side plates 2 are parallel to each other. A horizontal plate 3 is connected to each opposite surface of the side plates 2 on both sides of the fixing frame 1. The axes of the two horizontal plates 3 are parallel to both the side plates 2 and the upper surface of the fixing frame 1. At least one of the horizontal plates 3 is slidably connected to its corresponding side plate 2, and the sliding direction is parallel to the axis of the horizontal plate 3. A linear motion drive device is provided on the side plate 2, and the linear motion drive device is connected to the horizontal plate 3. A medicine tube holding device is provided directly below the gap between the two horizontal plates 3 on the fixing frame 1.
[0028] In this embodiment, during use, the medicine tube 16 is vertically inserted downwards into the medicine tube holding device through the gap between the two horizontal plates 3. At this time, the connecting ears 16-1 of the medicine tube 16 are not aligned. When the direction of the connecting ears 16-1 of some medicine tubes 16 is parallel to the axis of the horizontal plate 3, the medicine tube 16 will fall completely into the medicine tube holding device through the gap between the two horizontal plates 3. However, for some medicine tubes 16 whose connecting ears 16-1 are not parallel to the axis of the horizontal plate 3, the horizontal plates 3 are driven by a linear motion drive device, so that the two horizontal plates 3 move axially relative to each other in opposite directions. At this time, the two horizontal plates 3 rub the medicine tube 16. When the medicine tube 16... When the direction of the connecting ear 16-1 is rubbed by the two horizontal plates 16-1 until it is parallel to the axis of the horizontal plate 3, the liquid tube 16 falls completely into the liquid tube holding device. At this time, the direction of the connecting ear 16-1 of all the liquid tubes 16 in the liquid tube holding device is consistent and parallel to the axis of the horizontal plate 3. Then, the axis of the gap between the two horizontal plates 3 of the whole device is adjusted so that it corresponds to the slot of the syringe to be assembled. At this time, when the robot arm picks up the liquid tube 16, it can directly insert it into the corresponding syringe without having to make the direction of the connecting ear 16-1 of the liquid tube 16 consistent with the slot in the syringe. This solves the problem that there is currently no machine that can quickly correct the orientation of the connecting ear of the liquid tube.
[0029] As a preferred embodiment, each of the two horizontal plates 3 is slidably connected to its respective side plate 2, and both side plates 2 are equipped with the linear motion drive device. This arrangement allows for faster relative movement between the two horizontal plates 3, thereby increasing the efficiency of adjusting the direction of the connecting lug 16-1 of the liquid tube 16.
[0030] As a preferred embodiment, one of the two horizontal plates 3 is slidably connected to the side plate 2 on which it is located. The linear motion drive device is provided on the side plate 2 that is slidably connected to the horizontal plate 3. The linear motion drive device is connected to the horizontal plate 3 on the same side plate 2. This reduces the need for installing one linear motion drive device, thus saving manufacturing costs.
[0031] As a preferred embodiment, each of the two horizontal plates 3 is slidably connected to its respective side plate 2. One of the horizontal plates 3 is equipped with a linear motion drive device, which is a cylinder 4. The cylinder 4 is fixed to the side plate 2, and the free end of the piston rod 5 of the cylinder 2 is fixedly connected to the horizontal plate 3 on the side plate 2 where the cylinder 4 is located. The piston rod 5 is parallel to the axis of the horizontal plate 3. The two horizontal plates 3 are connected by a reverse drive. This configuration allows both horizontal plates 3 to move using only one cylinder 4 as the linear motion drive device, saving manufacturing costs and improving the efficiency of adjusting the direction of the connecting lug 16-1 of the liquid tube 16.
[0032] In a preferred embodiment, the reverse drive includes a belt 6 and two pulleys 7. The two pulleys 7 are respectively located at both ends of the gap formed between the two horizontal plates 3. The belt 6 is sleeved on the pulleys 7, and one of the horizontal plates 3 is fixedly connected to each of the two opposite sidewalls of the belt 6. Using the belt 6 and pulleys 7 as a reverse drive facilitates assembly during the manufacturing process of this invention and saves assembly time.
[0033] As a preferred method, such as Figure 7 As shown, the reverse drive consists of two gears 8. Each of the two horizontal plates 3 has a row of teeth 9 on its opposing surfaces. The teeth 9 are arranged in a formation parallel to the axis of the horizontal plates 3. The two gears 8 are respectively located at both ends of the gap formed between the two horizontal plates 3, and each gear 8 simultaneously meshes with both horizontal plates 3. This prevents slippage when the two horizontal plates 3 move relative to each other.
[0034] As a preferred embodiment, the liquid container is a cylindrical body 10 with its opening facing upwards.
[0035] As a preferred embodiment, the fixing frame 1 is also equipped with a photoelectric detection sensor 11. Each cylinder 10 has a light-transmitting hole 12 on its side wall, and the sensing surface of the photoelectric detection sensor 11 faces the light-transmitting hole 12. The photoelectric detection sensor 11 is connected to the linear motion drive device. The photoelectric detection sensor 11 detects whether there is a medicine tube 16 inside the cylinder 10. If not, it means that the medicine tube 16, which has been adjusted to the direction of the connecting ear 16-1, has been completely picked up by the robotic arm. The photoelectric detection sensor 11 then sends a signal to the linear motion drive device, causing the linear motion drive device to drive the two horizontal plates 2 to move relative to each other.
[0036] As a preferred embodiment, the system also includes a platform 13, on which a fixing frame 1 is provided on each of two opposite sides. The two fixing frames 1 are parallel to each other. The platform 13 is mounted on a support frame 15, and a motor 14 is mounted on the support frame 15. The output shaft of the motor 14 is fixedly connected to the geometric center of the platform 13. By setting up the platform 13 and simultaneously providing two sets of components for adjusting the direction of the connecting ears 16-1 of the liquid tube 16, the present invention allows for simultaneous adjustment of the direction of the connecting ears 16-1 of the liquid tube 16 using the other set of components while one set of components is being used by the robotic arm to grip the tube, thus increasing work efficiency.
[0037] As a preferred embodiment, the cross-section of the horizontal plate 3 is shaped like a figure 7. This figure 7 design prevents friction between the two horizontal plates 3 on the liquid tube 16 from occurring between the time the direction of the connecting lug 16-1 of the liquid tube 16 is adjusted and the liquid tube 16 is fully inserted into the cylinder 10.
