Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and more specifically to a flow stopper insertion device and insertion method. Background Technology

[0002] A flow stopper can be installed on a conduit to cut off or slow down the flow of the medium inside the conduit. It functions like a manual valve and is simple and quick to operate. It is often used to stop the flow of small hoses.

[0003] The flow stopper is ring-shaped with openings at both ends, allowing it to open and close at a certain angle. It also possesses a degree of elasticity, rebounding after being opened to a certain angle. For example... Figure 1 As shown, the flow stopper has a mounting hole at each end and a pair of protruding locking blocks on its inner side. The conduit can pass through the mounting hole on one side of the flow stopper, the pair of locking blocks, and the mounting hole on the other side in sequence. In its natural state, the flow stopper is closed due to its own elasticity, and the conduit is pressed tightly by the pair of protrusions, thus stopping or limiting the flow of the medium inside the conduit. When the opening of the flow stopper is widened, the pair of protrusions move away from each other, the conduit returns to its original position, and the flow stopper is in the open state, no longer affecting the flow of the medium inside the conduit.

[0004] When installing a flow stopper and conduit, the flow stopper opening must first be manually opened, and then the conduit must be inserted into the flow stopper. During this process, it is difficult to control the force used to manually open the flow stopper. If too little force is used, the friction between the protrusions and the conduit is too great, making installation difficult; if too much force is used, the flow stopper may exceed its maximum elastic deformation, leading to damage and unusable equipment. Therefore, there is an urgent need for automated equipment capable of installing flow stoppers and conduits to improve installation efficiency and yield. Summary of the Invention

[0021] Both the primary catheter clamping assembly and the secondary catheter clamping assembly are capable of vertical movement and clamping the catheter; the clamping force of the primary catheter clamping assembly is greater than that of the secondary catheter clamping assembly.

[0022] Optionally, the primary catheter clamping assembly is provided with multiple pairs of clamping arms.

After the clamping mechanism is released, the flow stop automatically returns to the closed state and locks into the conduit. This flow stop insertion device automates the assembly of the flow stop and conduit, significantly improving installation efficiency and yield. Attached Figure Description

[0064] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0066] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0067] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0068] See Figures 2 to 5 This invention provides a flow stopper insertion device, which includes a support 1 and a flow stopper feeding mechanism 2, a transfer mechanism 3, a flow stopper opening mechanism 4, a flow stopper clamping mechanism 5, and a conduit clamping mechanism 6 disposed on the support 1. The transfer mechanism 3 is slidably connected to the support 1. The transfer mechanism 3 can move up and down in the vertical direction to pick up material from the flow stopper feeding mechanism 2. The flow stopper opening mechanism 4 can move up and down in the vertical direction to pick up material from the transfer mechanism 3. The flow stopper opening mechanism 4 can switch the flow stopper 7 from a closed state to an open state. The flow stopper clamping mechanism 5 is slidably connected to the support 1 and can pick up material from the flow stopper opening mechanism 4 while maintaining the open state of clamping. The conduit clamping mechanism 6 clamps a conduit 8, and the flow stopper clamping mechanism 5 can sleeve the flow stopper 7 onto the conduit 8.

[0069] In this embodiment, a dual-channel assembly method is adopted, that is, two production lines are integrated. The stopper insertion device can perform the assembly of two stoppers 7 simultaneously, which improves the assembly efficiency. The stopper feeding mechanism 2, the stopper opening mechanism 4, and the guide tube clamping mechanism 6 are all located inside the bracket 1. The transfer mechanism 3 and the stopper clamping mechanism 5 are set on the top of the bracket 1, and the two share the same sliding track, which greatly saves the space occupied by the equipment.

[0070] The flow stop opening mechanism 4 can switch the flow stop 7 from the closed state to the open state, that is, open the opening 73 of the flow stop 7 by a set angle to facilitate subsequent assembly with the conduit 8. The flow stop clamping mechanism 5 keeps the flow stop 7 in the open state during clamping, allowing the flow stop 7 to be inserted into the conduit 8. After the flow stop clamping mechanism 5 releases the clamp, the flow stop 7 automatically returns to the closed state and locks into the conduit 8. The flow stop insertion device realizes automated assembly of the flow stop 7 and the conduit 8, greatly improving installation efficiency and yield.

[0071] The driving devices used in this application are cylinders or servo motors. Alternatively, devices can be selected according to actual needs, such as hydraulic cylinders, linear motors, electric push rods, or motors. For ease of description, this invention uses "sliding module" to refer to the connection method of cylinder-driven slider sliding, "telescopic module" to refer to the connection method of servo motor-driven connecting plate telescopic extension, and "clamping module" to refer to the connection method of cylinder-driven paired grippers clamping or releasing materials.

[0072] like Figure 6 and Figure 7 As shown, the flow stop opening mechanism 4 includes a primary limiter 41, a secondary limiter 42, a pusher 43, a fixture 44, and a first lifting driver 45. The first lifting driver 45 is mounted on the bracket 1. The fixture 44 is connected to the telescopic rod of the first lifting driver 45, and the first lifting driver 45 can drive the fixture 44 to move vertically. The fixture 44 is used to hold the flow stop 7, and its shape is adapted to the shape of the flow stop 7. The primary limiter 41, the secondary limiter 42, and the pusher 43 are all mounted on the fixture 44. The primary limiter 41 can pass through the mounting hole 74 of the flow stop 7. The pusher 43 can push the flow stop 7 from the closed state to the open state. The secondary limiter 42 can limit the maximum opening angle of the flow stop 7. The closed state is the natural state of the flow stop 7. Figure 7 The first flow stopper 71 is in the closed state, which locks the conduit 8, thus cutting off or limiting the flow of the medium inside the conduit 8; the open state is the open state of the flow stopper 7. Figure 7 The second stopper 72 is in the open state, the opening 73 of the stopper 7 is enlarged, the distance between the pair of locking blocks 75 is increased, the squeezing force on the conduit 8 is reduced or no longer squeezed, the flow rate of the medium in the conduit 8 is increased, and it is also convenient to move and disassemble the stopper 7.

[0073] Specifically, the first lifting driver 45 is a telescopic module. The first lifting driver 45 can drive the primary limiter 41, the secondary limiter 42, the pusher 43, and the fixture 44 to lift synchronously to pick up materials on the transfer mechanism 3. The primary limiter 41, the secondary limiter 42, and the pusher 43 are all equipped with sliding modules. A positioning rod is provided on the slider of the primary limiter 41. The positioning rod is driven by the cylinder of the primary limiter 41 to move so that it can pass into the mounting hole 74 of the stopper 7 placed in the fixture 44, thereby limiting the stopper 7 and effectively preventing the stopper 7 from being misaligned or detached from the fixture 44 during the process of the pusher 43 opening the stopper 7. The slider of the secondary limiter 42 is provided with a limit strip, which is adapted to the shape of the contact surface of the flow stopper 7 to limit the maximum opening angle of the flow stopper 7. This effectively prevents the flow stopper 7 from exceeding its elastic deformation range due to an excessive opening angle during opening, thereby improving the product yield. In this embodiment, the secondary limiter 42 and the primary limiter 41 are located on the same side, and the cylinder of the primary limiter 41 is located inside the secondary limiter 42. The limit strip is provided with a clearance groove for avoiding gaps with the limit rod, further optimizing the space occupied by the equipment. Similar to the secondary limiter 42, the pusher 43 has a push bar on its slider. The push bar is adapted to the contact surface of the stopper 7. When the cylinder of the pusher 43 drives the slider to move toward the stopper 7, the push bar can gradually open the stopper 7, that is, gradually expand the opening 73 of the stopper 7 until the stopper 7 abuts against the limit bar of the secondary limiter 42, thus completing the opening operation of the stopper 7, which facilitates the subsequent assembly operation with the conduit 8.

[0074] Secondly, the flow stop opening mechanism 4 also includes a vacuum nozzle and a material detector mounted on the fixture 44; the outlet of the vacuum nozzle faces the flow stop 7 on the fixture 44. The material detector can be a laser sensor, used to detect whether the flow stop 7 on the fixture 44 is properly positioned. If it is not properly positioned or not positioned at all, the laser sensor transmits this information to the controller, such as a PLC, and the controller then controls the vacuum nozzle to blow air to ensure that there is no flow stop 7 on the fixture 44. This effectively avoids product damage and scrapping during installation due to misalignment of the flow stop 7, such as the collision between the positioning rod of the first-level limiter 41 and the flow stop 7, thereby saving material costs and protecting the equipment; at the same time, it can also effectively avoid affecting the opening operation of the flow stop 7 at another station.

[0075] See Figure 8 and Figure 9The catheter clamping mechanism 6 includes a primary catheter clamping assembly 61 and multiple secondary catheter clamping assemblies 62 arranged along the axial direction of the catheter 8. The secondary catheter clamping assemblies 62 are located near the flow stop opening mechanism 4, while the primary catheter clamping assemblies 61 are located away from the flow stop opening mechanism 4. Both the primary catheter clamping assembly 61 and the secondary catheter clamping assemblies 62 can move up and down in the vertical direction and can clamp the catheter 8. The clamping force of the primary catheter clamping assembly 61 is greater than that of the secondary catheter clamping assembly 62. Specifically, the secondary catheter clamping assembly 62 includes a telescopic module and a clamping module. The telescopic module is mounted on the support 1, and the clamping module is connected to the connecting plate of the telescopic module to drive the clamping module to move up and down in the vertical direction. The clamping module is provided with a pair of grippers, which can clamp or release the catheter 8. In this embodiment, the structure of the primary catheter clamping assembly 61 and the secondary catheter clamping assembly 62 is the same, but the air pressure of the cylinder of the primary catheter clamping assembly 61 is greater than that of the cylinder of the secondary catheter clamping assembly 62, that is, the clamping force of the primary catheter clamping assembly 61 is greater, so as to serve as the fixed end of the catheter 8, effectively preventing the catheter 8 from shifting when it is assembled with the stopper 7.

[0076] Since the conduit 8 is a flexible tube, it will bend downwards when horizontally suspended and clamped. Therefore, this invention uses a multi-stage conduit clamping assembly to fix the conduit 8, ensuring that its axis is horizontal, facilitating the subsequent alignment of the stopper 7 with the conduit 8. During assembly, the stopper clamping mechanism 5 clamps the stopper 7 in its open state and moves it to the assembly station. At this time, the mounting hole 74 of the stopper 7 is coaxial with the conduit 8. The stopper 7 and the conduit 8 are assembled through multiple insertion operations. Figure 9 Taking the orientation and number of secondary conduit clamping assemblies 62 as an example, during the first insertion, after the stopper clamping mechanism 5 slides horizontally a set distance, the stopper 7 moves a set distance on the conduit 8, and the rightmost secondary conduit clamping assembly 62 is released and descends. During the second clamping, after the stopper clamping mechanism 5 slides horizontally a set distance, the stopper 7 moves a set distance on the conduit 8, and the middle secondary conduit clamping assembly 62 is released and descends, thus completing the insertion operation. The specific number of insertion operations can be set according to actual needs. It should be noted that the function of the primary conduit clamping assembly 61 is to fix the conduit 8 and improve the stability of the stopper 7 and conduit 8 during insertion, while the secondary conduit clamping assembly 62 serves to temporarily fix the conduit 8. By performing multiple insertion operations with multiple secondary conduit clamping assemblies 62, the horizontal accuracy of the conduit 8 can be improved, ensuring the alignment accuracy with the mounting hole 74 of the stopper 7, thereby improving the insertion efficiency.

[0077] In another embodiment, the primary catheter clamping assembly 61 is provided with multiple pairs of clamping arms 611. The air pressure of the cylinders of the primary catheter clamping assembly 61 and the secondary catheter clamping assembly 62 is the same, but by providing multiple pairs of clamping arms 611, the primary catheter clamping assembly 61 can increase the friction between the primary catheter clamping assembly 61 and the catheter 8, making the catheter 8 less prone to displacement and improving the stability of the catheter 8 during insertion.

[0078] like Figure 10 As shown, the flow stopper feeding mechanism 2 includes a first rotary driver 21 and a placement frame 22. The first rotary driver 21 is mounted on the support 1. The placement frame 22 is connected to the shaft of the first rotary driver 21, and the first rotary driver 21 can drive the placement frame 22 to rotate in the horizontal plane. The placement frame 22 serves the same function as the fixture 44, for placing the flow stopper 7. The flow stopper 7 is placed onto the placement frame 22 by an external feeding device. The flow stopper feeding mechanism 2 can be further equipped with a sliding module. Both the first rotary driver 21 and the placement frame 22 are mounted on the sliding module to compensate for the travel distance of the external feeding device and the flow stopper opening mechanism 4. The flow stopper 7 has two working conditions: forward placement and reverse placement. However, the flow stopper opening mechanism 4 can only open the flow stopper 7 in the set placement direction. Therefore, the flow stopper feeding mechanism 2 needs to uniformly convert the flow stopper 7 to the set placement direction of the flow stopper 7 on the flow stopper opening mechanism 4. Specifically, the first rotary drive 21 is a cylinder that can drive the placement rack 22 to rotate, thereby changing the assembly direction of the flow stopper 7. A laser sensor is correspondingly installed on the placement rack 22, which can detect the placement position of the flow stopper 7 and adjust the orientation of the flow stopper 7 accordingly to meet production needs and reduce the requirement for setting up external feeding equipment.

[0079] See Figure 11 The transfer mechanism 3 includes a second lifting driver 31 and a first clamp 32. The second lifting driver 31 is slidably connected to the bracket 1. The first clamp 32 is mounted on the second lifting driver 31, and the second lifting driver 31 can drive the first clamp 32 to move up and down in the vertical direction. The second lifting driver 31 slides through a sliding module set on the bracket 1. The second lifting driver 31 itself is a sliding module, and the first clamp 32 is a clamping module, so that the first clamp 32 can slide and move up and down relative to the bracket 1, and cooperate with the stopper feeding mechanism 2 to pick up materials, realizing the transfer of the stopper 7 between the stopper feeding mechanism 2 and the stopper opening mechanism 4.

[0080] See Figure 12The flow stop clamping mechanism 5 includes a second rotary drive 51 and a second clamp 52. The second rotary drive 51 is slidably connected to the bracket 1. The second clamp 52 is connected to the shaft of the second rotary drive 51. The second clamp 52 can clamp the flow stop 7 and keep the flow stop 7 in the open state. The shape of the jaws of the second clamp 52 is adapted to the internal shape of the flow stop 7 in the open state, so that the flow stop 7 can be clamped in the open state and subsequent insertion operations can be performed. Since the flow stop opening mechanism 4 can be raised and lowered, the jaws of the second clamp 52 and the guide tube 8 can be set at the same height. After the second clamp 52 clamps the flow stop 7, no raising or lowering adjustment is required. The flow stop clamping mechanism 5 can slide horizontally on the bracket 1 to perform the insertion operation, further simplifying the equipment.

[0081] In this operating condition, the diameter of one end of the conduit 8 is larger than the diameter of the other end. The flow stopper 7 is also positioned either forward or reverse, depending on the orientation of the two mounting holes 74. Therefore, during assembly, the forward and reverse installation of the conduit 8 and the flow stopper 7 needs to be considered. This invention mainly addresses the issue of the forward and reverse placement of the flow stopper 7 by designing the equipment, with the conduit 8 set to a uniform orientation. Specifically, the second rotary driver 51 can drive the second clamp 52 to rotate, switching the orientation of the flow stopper 7, i.e., switching between the two workstations. This swaps the two flow stoppers 7 in the two workstations, allowing the flow stopper 7 to be inserted into the conduit 8 in the set direction, improving the adaptability of the flow stopper 7 and the conduit 8 to various installation methods. To further improve the stability of the transmission, a drag chain can be installed at the top of the bracket 1. The transfer mechanism 3 and the flow stopper clamping mechanism 5 are respectively assisted by drag chains on their corresponding sides to improve the stability of the transmission.

[0082] Furthermore, the present invention also provides a method for inserting a flow stopper insertion device, the method being implemented based on the flow stopper insertion device described above, the insertion method comprising:

[0083] The feed mechanism 2 of the flow stopper unifies the orientation of the flow stopper 7;

[0084] After the transfer mechanism 3 slides above the flow stopper feeding mechanism 2, it descends to pick up the material;

[0085] The transfer mechanism 3 rises and slides above the stopper opening mechanism 4, and the stopper opening mechanism 4 rises to pick up the material; the transfer mechanism 3 can compensate and adjust the lifting stroke of the stopper opening mechanism 4 by lifting and lowering.

[0086] The flow stop opening mechanism 4 descends to open the flow stop 7; specifically, the flow stop 7 is fixed in the fixture 44 by the first-level limiter 41, the maximum opening angle of the flow stop 7 is limited by the second-level limiter 42, and the opening 73 of the flow stop 7 is expanded by the pusher 43, and finally the flow stop 7 is opened.

[0087] The flow stop clamping mechanism 5 moves above the flow stop opening mechanism 4, the flow stop opening mechanism 4 rises, and the flow stop clamping mechanism 5 picks up the material.

[0088] The flow stop clamping mechanism 5 slides to the conduit clamping mechanism 6. The flow stop clamping mechanism 5 slides on the bracket 1 and, through multiple insertion operations, the flow stop 7 is fitted onto the conduit 8 at the preset position.

[0089] Furthermore, after the stopper 7 has been inserted into the conduit 8 a set distance during the insertion process, the conduit clamping mechanism 6 releases its clamping on the side closest to the stopper 7 within the set distance, allowing the stopper 7 to be inserted into the conduit 8 again by the set distance. Specifically, using the clamping point on the side furthest from the stopper 7 as a reference point, the side closest to the stopper 7, i.e., the clamping point furthest from the reference point, allows the stopper 7 to continue being inserted by releasing one or more secondary conduit clamping components 62 within the set distance. By repeating the above steps multiple times, the stopper 7 can be inserted into the set position of the conduit 8, satisfying the automated assembly requirements of the stopper 7 and the conduit 8.

[0090] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of the present invention should be covered within the protection scope of the present invention.
