Description

Technical Field

[0001] The utility model relates to the technical field of medical device production equipment, in particular to an alignment mechanism and syringe production equipment. Background Art

[0002] Among medical devices, syringes for delivering liquid medicine into the human body are widely used. In order to facilitate the control of the amount of liquid sucked into the syringe, a scale is usually provided on the outer wall of the syringe barrel by printing or other means, so that when the liquid level in the syringe barrel reaches the corresponding scale value, the amount of liquid sucked into the syringe corresponds to the scale value.

[0003] During the production process of syringes, in order to ensure that the scale on the syringe barrel is clear and accurate, the syringe is usually inspected before packaging. However, when the transmission mechanism in the syringe production equipment, such as a conveyor belt, receives and transports the produced syringes, the scale on the syringe barrel may face downward. It is usually necessary to manually flip the syringe barrel so that the scale on the syringe barrel faces upward to facilitate subsequent inspection of the scale. This can easily lead to an increase in the manpower demand of the entire syringe production line and is not conducive to industrial automated production. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] It should be noted that, in the coordinate system XYZ provided herein, the positive direction of the X axis represents the right, the reverse direction of the X axis represents the left, the positive direction of the Y axis represents the front, the reverse direction of the Y axis represents the back, the positive direction of the Z axis represents the top, and the reverse direction of the Z axis represents the bottom. At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0027] On the one hand, an embodiment of the utility model provides an alignment mechanism, including: a frame 1, which is used to move synchronously with the transmission mechanism of the syringe production equipment; a clamping mechanism 2, which is installed on the frame 1 and is used to clamp the syringe barrel 4 on the transmission mechanism; a rotating mechanism 3, which is installed on the frame 1 and includes a drivingly connected rotating drive component 31 and a roller 32, and the rotating drive component 31 is used to drive the roller 32 to rotate. When the clamping mechanism 2 clamps the syringe barrel 4, the wheel surface of the roller 32 is against the barrel wall of the syringe barrel 4.

[0028] In this embodiment, if Figure 1As shown, a frame 1, a clamping mechanism 2 and a rotating mechanism 3 are provided to form an alignment mechanism, wherein the frame 1 can move synchronously with the transmission mechanism of the syringe production equipment, and the clamping mechanism 2 and the rotating mechanism 3 are both installed on the frame 1, so that the entire alignment mechanism can move synchronously with the transmission mechanism, and the transmission mechanism is provided with finished syringe barrels 4. Such a setting can facilitate the alignment operation of the syringe barrels 4 by the alignment mechanism, and at the same time, there is no need for the transmission mechanism to stop and wait, thereby ensuring the transmission of the syringe barrels 4, and further ensuring the automated production efficiency and stability of the entire syringe production equipment; on this basis, a rotating drive component 31 and a roller 32 connected by driving are provided to form the rotating mechanism 3 on the frame 1, and the rotating drive component 31 can drive the roller 32 Rotate, and at the same time, the clamping mechanism 2 on the frame 1 is set to clamp the syringe barrel 4 on the transmission mechanism. Through the clamping of the clamping mechanism 2, the syringe barrel 4 can be away from the transmission mechanism and close to the roller 32 until its barrel wall abuts against the wheel surface of the roller 32. In this way, when the rotary drive component 31 drives the roller 32 to rotate, due to the friction force generated by the abutment between the barrel wall of the syringe barrel 4 and the wheel surface of the roller 32, the rotation of the roller 32 can drive the syringe barrel 4 to rotate synchronously, and then the scale on the syringe barrel 4 moves to the side away from the transmission mechanism as the syringe barrel 4 rotates, thereby realizing automatic and rapid flipping of the syringe barrel 4, which effectively reduces the manpower demand of the entire syringe production line and meets the needs of industrial automation production.

[0029] It should be noted that in this embodiment, a control element electrically connected to the clamping mechanism 2 and the rotating drive assembly 31 is also provided. Specifically, the control element is a PLC controller, and the operator can control the operation of the clamping mechanism 2 and the rotating drive assembly 31 by outputting control instructions through the control element.

[0030] It should be noted that, in this embodiment, in order to ensure the structural stability of the frame 1, a connecting frame and a support block are provided to form the frame 1, wherein the connecting frame can be connected to a driving device that drives the frame 1 to move synchronously with the transmission mechanism, and there are multiple support blocks, and the multiple support blocks are filled into the connecting frame to form the frame 1, and form an installation position for the clamping mechanism 2 and the rotating mechanism 3 to be installed.

[0031] It should be noted that, in the present embodiment, in order to facilitate the clamping of the syringe barrel 4 by the clamping mechanism 2 and avoid interference of the alignment mechanism with the transmission of the syringe barrel 4, the frame 1 can be driven by a driving device connected to it toward or away from the transmission mechanism, so that the clamping mechanism 2 is close to or away from the syringe barrel 4. Of course, the clamping mechanism 2 can also be set so that the distance between it and the transmission mechanism when it is open is greater than or equal to the size of the syringe barrel 4 along the direction toward the clamping mechanism 2, and the syringe barrel 4 can be clamped when it is closed.

[0032] Optionally, the rotating mechanism 3 also includes a transmission assembly 33, and the clamping mechanism 2, the roller 32 and the transmission assembly 33 cooperate to form a flipping module. There are multiple flipping modules, and the multiple flipping modules are distributed on the frame 1 at intervals, and are used to correspond one-to-one with the syringe barrels 4 placed at intervals on the transmission mechanism. The rotation drive assembly 31 is driven and connected to the roller 32 through the transmission assembly 33, and the transmission assembly 33 is used to drive connect or separate with the rotation drive assembly 31.

[0033] Since the syringe barrels 4 transported on the transport mechanism are usually produced in batches, that is, the transport mechanism receives and transports a plurality of syringe barrels 4 of a batch at a time, in order to realize the flipping of the syringe barrel 4 while moving synchronously with the transport mechanism, in this embodiment, as shown in FIG. Figure 1 As shown, on the same frame 1, the clamping mechanism 2 and the roller 32 are combined to form a flipping module. At the same time, multiple flipping modules are arranged and spaced apart on the frame 1. The flipping modules can correspond one-to-one to the syringe barrels 4 spaced apart on the transmission mechanism. Specifically, the clamping mechanism 2 of the flipping module can correspond one-to-one to the placement groove on the transmission mechanism for placing the syringe barrel 4. With this arrangement, when the syringe barrel 4 is flipped, the syringe barrel 4 to be flipped can be clamped and flipped at the same time by multiple flipping modules, which does not affect the transmission of the syringe barrel 4 for subsequent packaging inspection and can also improve the flipping efficiency of all syringe barrels 4 through synchronous flipping. On this basis, the rotating mechanism 3 is also provided with a transmission component 33, and the transmission component 33 is also a part of the flipping module, wherein the rotation drive component 31 can be driven and connected to the roller 32 through the transmission component 33, and the transmission component 33 can be driven and connected or separated from the rotation drive component 31. In this way, when the syringe barrel 4 corresponding to the flipping module needs to be flipped, it can be driven and connected to the rotation drive component 31 through the transmission component 33, so that the rotation drive component 31 drives the roller 32, thereby driving the flipping of the syringe barrel 4. If the syringe barrel 4 corresponding to the flipping module does not need to be flipped, the transmission component 33 can be separated from the rotation drive component 31, so that the rotation drive component 31 cannot drive the corresponding roller 32, and the corresponding syringe barrel 4 will not flip, thereby realizing the targeted flipping of multiple syringe barrels 4 on the transmission mechanism.

[0034] It should be noted that, in this embodiment, a control element electrically connected to the clamping mechanism 2, the rotating drive component 31 and the transmission component 33 is also provided. Specifically, the control element is a PLC controller, and the operator can control the operation of the clamping mechanism 2, the rotating drive component 31 and the transmission component 33 by outputting control instructions through the control element.

[0035] Optionally, the transmission assembly 33 includes a mobile driving member 331, a transmission shaft 332 and a connecting member 333. The mobile driving member 331 is drivingly connected to the transmission shaft 332, the roller 32 is installed on the transmission shaft 332, and the connecting member 333 is connected to the transmission shaft 332. The mobile driving member 331 is used to drive the transmission shaft 332 to move reciprocatingly to drive the connecting member 333 to be driven and connected or separated from the rotating driving assembly 31.

[0036] In this embodiment, if Figure 3 As shown, a mobile driving member 331, a transmission shaft 332 and a connecting member 333 are provided to form a transmission assembly 33, wherein the mobile driving member 331 is drivingly connected to the transmission shaft 332, and the connecting member 333 is connected to the transmission shaft 332. The mobile driving member 331 can drive the transmission shaft 332 to move back and forth, thereby driving the connecting member 333 to be connected or separated from the rotating driving assembly 31. The roller 32 is installed on the transmission shaft 332, so that the rotating driving assembly 31 can drive and stop the rotation of the roller 32 through the connecting member 333 and the transmission shaft 332.

[0037] For example, a friction plate is provided as the connecting member 333, and a magnetic member is provided as the movable driving member 331, wherein the magnetic member can realize the presence or absence of magnetism by turning the power on and off, and the transmission shaft 332 is made of iron or other materials that can be adsorbed by the magnetic member, and the magnetic member adsorbs the transmission shaft 332 by turning on the power, at which time the transmission shaft 332 can move toward the magnetic member and drive the connecting member 333 to move, thereby making the connecting member 333 abut against the driving end of the rotating driving component 31, and the connecting member 333 is a friction plate, and the friction plate can generate friction with the rotating driving component 31, and then when the rotating driving component 31 outputs the driving force, the transmission shaft 332 is driven to rotate by the friction.

[0038] Optionally, the rotating drive assembly 31 includes a gear 311, a rack 312 and a telescopic drive member 313, the gear 311 is coaxially connected to the roller 32, the rack 312 is drivingly connected to the telescopic drive member 313 and meshes with the gear 311, and the telescopic drive member 313 is used to drive the rack 312 to move back and forth to drive the gear 311 to rotate back and forth.

[0039] In this embodiment, if Figure 2 A gear 311, a rack 312 and a telescopic driving member 313 are arranged to form a rotating driving component 31, wherein the gear 311 is coaxially connected to the roller 32, and the rack 312 is drivingly connected to the telescopic driving member 313 and meshes with the gear 311. The telescopic driving member 313 can output a linear driving force to drive the rack 312 to move back and forth. Due to the linear movement of the rack 312, the gear 311 meshing with the rack 312 can be driven to rotate, and then the roller 32 coaxially connected to the gear 311 can be driven to rotate, and the syringe barrel 4 can be flipped through the friction force and the rotational driving force of the roller 32.

[0040] It should be noted that, in the present embodiment, the telescopic driving member is a telescopic cylinder, and in other embodiments of the present utility model, the telescopic driving member may also be a telescopic electric cylinder or other structures.

[0041] Optionally, a limiting hole 3121 is provided on the rack 312, and a limiting member 3122 passes through the limiting hole 3121. The limiting member 3122 is connected to the frame 1. When the telescopic driving member 313 drives the rack 312 to reciprocate, the limiting member 3122 is used to move relative to the limiting hole 3121 along the moving direction of the rack 312, and is used to abut against a side wall of the limiting hole 3121 along the moving direction of the rack 312.

[0042] In order to ensure the accuracy of the syringe barrel 4 flipping, in this embodiment, Figure 2 A limiting hole 3121 is provided on the rack 312, wherein a limiting member 3122 is provided through the limiting hole 3121, and the limiting member 3122 can be connected to the frame 1. At the same time, when the telescopic driving member 313 drives the rack 312 to move back and forth, the limiting member 3122 can move relative to the limiting hole 3121 along the moving direction of the rack 312, that is, the spatial extension direction of the limiting hole 3121 for the limiting member 3122 to move is consistent with the moving direction of the rack 312. The limiting member 3122 can also abut against a side wall of the limiting hole 3121 along the moving direction of the rack 312, that is, when the rack 312 and the gear 311 drive the roller 32 to drive the syringe barrel 4 to flip into place, the limiting member 3122 can limit the movement of the rack 312 through the limiting hole 3121, so that at this time the telescopic driving member 313 outputs the driving force again and the rack 312 also remains still, thereby ensuring the flipping accuracy of the syringe barrel 4.

[0043] Optionally, the clamping mechanism 2 includes a clamping jaw 21 and a clamping drive 22, the clamping drive 22 is connected to the clamping jaw 21 and is used to drive the clamping jaw 21 to open or close. When the clamping jaw 21 closes to clamp the syringe barrel 4, the inner wall of the clamping jaw 21 is used to abut against the wall of the syringe barrel 4.

[0044] In this embodiment, if Figure 1 As shown, a clamping mechanism 2 is composed of a clamping jaw 21 and a clamping drive member 22, wherein the clamping drive member 22 is connected to the clamping jaw 21 and can drive the clamping jaw 21 to open or close, thereby grasping and putting down the syringe barrel 4. When the clamping jaw 21 closes to clamp the syringe barrel 4, the inner wall of the clamping jaw 21 can be against the barrel wall of the syringe barrel 4, thereby separating the syringe barrel 4 from the transmission mechanism and effectively supporting the syringe barrel 4.

[0045] It should be noted that, in the present embodiment, the clamping drive member 22 is a telescopic drive structure, specifically a telescopic electric cylinder or a telescopic pneumatic cylinder.

[0046] Optionally, the clamping jaw 21 includes two clamping plates 211 arranged opposite to each other, and the roller 32 is located between the two clamping plates 211. The end of any clamping plate 211 close to the transmission mechanism is used to extend toward the transmission mechanism, and is bent toward the other clamping plate 211 to form a support portion 212. When the clamping jaw 21 is closed to clamp the syringe barrel 4, the support portion 212 and the roller 32 are used to accommodate the syringe barrel 4, and the support portion 212 is against the barrel wall of the syringe barrel 4.

[0047] In this embodiment, if Figure 2 Two clamping plates 211 arranged opposite to each other are arranged to form a clamping jaw 21, wherein a roller 32 is located between the two clamping plates 211, and an end portion of any clamping plate 211 close to the transmission mechanism is used to extend toward the transmission mechanism, and is bent toward the other clamping plate 211 to form a supporting portion 212, so that the clamping plate 211 forms a bent structure. At the same time, when the clamping jaw 21 is closed to clamp the syringe barrel 4, the syringe barrel 4 can be accommodated between the supporting portion 212 and the roller 32, so that the syringe barrel 4 can be abutted against the wheel surface of the roller 32, so that the rotating roller 32 drives the syringe barrel 4 to flip over, and at the same time, the supporting portion 212 abuts against the barrel wall of the syringe barrel 4 to support the syringe barrel 4 and ensure the stability of the syringe barrel 4 when it is flipped.

[0048] Optionally, the clamping mechanism 2 further includes a positioning plate 23 , on which is provided a positioning opening 231 for opening toward the transmission mechanism, the positioning opening 231 being used to accommodate the syringe barrel 4 , and when the syringe barrel 4 is located in the positioning opening 231 , the clamping jaws 21 are used to close and clamp the syringe barrel 4 .

[0049] In order to facilitate the positioning of the syringe barrel 4, the clamping jaws 21 can clamp the syringe barrel 4. Figure 2 As shown, the clamping mechanism 2 is also provided with a positioning plate 23 having a positioning hole 231 that can be opened toward the transmission mechanism. Before the clamping mechanism 2 clamps the syringe barrel 4, the positioning hole 231 on the positioning plate 23 can accommodate the syringe barrel 4 in position to prevent the syringe barrel 4 from deviation when the clamping claws 21 clamp it, thereby ensuring the accuracy and stability of clamping.

[0050] Optionally, a friction layer 321 is provided on the wheel surface of the roller 32 .

[0051] In this embodiment, if Figure 1 As shown, in order to ensure the driving effect of the roller 32 on the rotation of the syringe barrel 4, a friction layer 321 is provided on the wheel surface of the roller 32. Specifically, the friction layer 321 can be concave or convex or concave-convex on the wheel surface of the roller 32, thereby effectively improving the friction force generated between the roller 32 and the syringe barrel 4 under the same abutment force.

[0052] On the other hand, an embodiment of the present invention provides a syringe production device, including a transmission mechanism and the above-mentioned alignment mechanism.

[0053] The technical effect of the syringe production equipment in this embodiment is similar to the technical effect of the above-mentioned alignment mechanism, and will not be repeated here.

[0054] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
