Description

Technical Field

[0001] This invention belongs to the field of medical consumable assembly technology, and relates to an assembly method and apparatus, particularly to a method and apparatus for assembling inner and outer shells. Background Technology

[0002] The current market generally prioritizes the safety of medical consumables during use, and triggerable retraction structures are a common design feature; however, these structures are often difficult to assemble. For example... Figure 6 As shown, components such as the outer shell, spring, and inner shell are assembled into one unit. During the assembly process, materials are prone to jamming and damage, components may fall off, and the device may fail to trigger after assembly or be triggered during assembly. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a method for assembling inner and outer shells. It solves the technical problems that easily arise during the assembly of inner and outer shells in the prior art.

[0004] The objective of this invention can be achieved through the following technical solutions: A method for assembling inner and outer shells includes the following steps: S10, Outer shell loading: Place the outer shell horizontally on the limiting groove of the outer shell carrier, and the guide pin passes through the hollow part of the outer shell in the horizontal direction; S20, Spring in position: The spring is fitted onto the guide pin, allowing part of the guide pin to pass through the spring; S30, Inner shell loading: Place the inner shell horizontally on the guide groove of the inner shell carrier; S40, Inner shell and guide pin docking: The inner shell carrier is close to the outer shell carrier, so that the inner shell and the outer shell are aligned in the same straight line, and one end of the inner shell is close to the guide pin, so that the structure of the inner shell with the spring docks with the guide pin; S50, Inner and outer shell assembly: The push rod pushes the inner shell to move towards the outer shell along the guide groove, and synchronously drives the guide pin to exit the outer shell until the assembly is completed and the movement of the guide pin is restricted.

[0005] This invention assembles the outer shell, spring, and inner shell by placing them horizontally. This simplifies the assembly process by using clamps to fix the outer shell and grip and move the inner shell, reducing the number of structures that would apply force to the outer shell or inner shell. The inner and outer shells are only subjected to force in the assembly direction to complete the assembly, thus solving the technical problems that are prone to occur during the assembly of the inner and outer shells.

[0006] In the above-described method for assembling inner and outer shells, the S10 shell loading step further includes the following steps: S11: The guide pin moves from one side of the outer casing carrier toward the outer casing, and the guide pin passes through the hollow part of the outer casing in the horizontal direction.

[0007] In the above-described method for assembling inner and outer shells, the S50 inner and outer shell assembly step further includes the following steps: S51: The auxiliary component descends close to the outer shell carrier, restricting the spring, inner shell, and outer shell in the height direction.

[0008] This invention uses auxiliary components to limit the height of the inner shell, outer shell, and spring, avoiding the problem of unstable assembly caused by the inner shell and outer shell shifting upwards under force during assembly, while also ensuring that the spring will not pop out to one side during compression.

[0009] In the above-described method for assembling inner and outer shells, the S30 inner shell feeding step further includes the following steps: S31: The turntable drives the outer shell carrier to move to the position corresponding to the inner shell carrier.

[0010] This invention uses a turntable to transport the outer shell carrier. Multiple outer shell carriers can be set around the turntable. By rotating the turntable, the new outer shell can be quickly aligned with the inner shell to complete the assembly. After assembly, the finished product can be quickly moved out and into a new outer shell, thereby improving the overall assembly efficiency.

[0011] Another objective of this invention is to address the aforementioned problems in the prior art by proposing an assembly device applicable to the above-described method for assembling inner and outer shells. This device eliminates various unexpected factors that may occur during the assembly process, ensuring the stability and reliability of the assembly results.

[0012] An inner and outer shell assembly device, wherein the device assembles the inner and outer shells using the aforementioned inner and outer shell assembly method, further includes an outer shell carrier, a guide pin assembly, an inner shell carrier, and a pushing assembly disposed on a worktable. The guide pin assembly is disposed on the side of the outer shell carrier away from the inner shell carrier, and the outer shell carrier has a limiting groove. The guide pin assembly includes a guide pin, which is movably disposed relative to the outer shell carrier. The guide pin can move towards or away from the outer shell carrier relative to the limiting groove. The inner shell carrier is movably disposed on the worktable and can move towards or away from the outer shell carrier relative to it. The pushing assembly is disposed on the side of the inner shell carrier away from the outer shell carrier, and the inner shell carrier has a guide groove. The pushing assembly includes a pushing rod, which can move towards or away from the inner shell carrier relative to the guide groove.

[0013] This invention uses an outer shell carrier and an inner shell carrier as placement platforms during the assembly of the outer and inner shells, allowing the inner and outer shells to be placed horizontally for stable assembly. This reduces the number of structures that would exert force on the inner or outer shells, allowing the inner and outer shells to be assembled only under the force in the assembly direction, thus solving the technical problems that are prone to occur during the assembly of inner and outer shells.

[0014] In the aforementioned inner and outer shell assembly device, the guide pin assembly further includes an elastic element and a movable plate. The assembly device is also provided with a positioning element, which is fixedly connected to the outer shell carrier. One end of the elastic element is connected to the movable plate, and the other end of the elastic element is connected to the positioning element.

[0015] In the above-mentioned inner and outer shell assembly device, the elastic element is a tension spring, and the positioning element is disposed between the moving plate and the outer shell carrier; Alternatively, the elastic element may be a spring, and the positioning element may be located on the side of the movable plate away from the outer casing carrier.

[0016] In the aforementioned inner and outer shell assembly device, a connector is fixedly connected to the bottom of the movable plate, and the connector is detachably connected to the extension rod of the limiting cylinder.

[0017] In the aforementioned inner and outer shell assembly device, a translation component is further included. The translation component includes a translation plate and a translation drive component. The inner shell carrier and the push component are both disposed on the translation plate. The translation drive component can drive the translation plate to move, thereby driving the inner shell carrier and the push component to move closer to and further away from the outer shell carrier. The push component includes a second movable plate and a push drive component. The second movable plate is movable relative to the translation plate. The push drive component is disposed on the translation plate. The push rod is fixedly disposed on the second movable plate. The push drive component can drive the second movable plate to move relative to the inner shell carrier.

[0018] In the aforementioned inner and outer shell assembly device, the pushing assembly further includes a push rod one, and the guide pin assembly further includes a push rod two. The push rod one is fixedly mounted on the movable plate two, and the push rod two is fixedly mounted on the movable plate one. When the inner shell carrier approaches the outer shell carrier, the push rod one aligns with the push rod two, and the pushing drive drives the push rod one to move. The push rod one pushes the push rod two to move, thereby driving the guide pin to move.

[0019] This invention employs a push rod assembly where push rod one pushes push rod two, thereby causing the guide pin to exit the outer shell. This simple structure achieves synchronization between push rod movement and pin exit, making the spring assembly on the inner shell more stable.

[0020] The aforementioned inner and outer shell assembly device further includes an auxiliary limiting component and a support frame. The support frame includes a support plate and a support column. The support plate is fixedly mounted on the worktable via the support column. The auxiliary limiting component includes an auxiliary component and a lifting plate. The auxiliary component is fixed to the side of the lifting plate facing the outer shell carrier. The lifting plate is movable up and down on the support plate.

[0021] This invention uses auxiliary components to limit the height of the inner shell, outer shell, and spring, avoiding the problem of unstable assembly caused by the inner shell and outer shell shifting upwards under force during assembly, while also ensuring that the spring will not pop out to one side during compression.

[0022] In the aforementioned inner and outer shell assembly device, a turntable is also included. The outer shell carrier and the guide pin assembly are both disposed on the turntable. A limit pin is provided on one side of the moving plate away from the outer shell carrier. The limit pin is slidably disposed on the turntable. A return spring is provided between the limit pin and the turntable. A pin release cylinder is provided below the turntable. The pin release cylinder drives a connecting plate. The connecting plate can drive the limit pin to move downward under the drive of the pin release cylinder.

[0023] Compared with existing technologies, the advantages of this product are: The horizontal assembly structure solves problems such as poor triggering after assembly. This structure fully considers various unexpected factors that may occur during the assembly process, ensuring the stability and reliability of the assembly result. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 5 As shown, the materials include an outer shell 101, an inner shell 102, and a spring 103. The spring 103 is located between the inner shell 102 and the outer shell 101, with one end fitted onto the inner shell 102 and the other end abutting against the outer shell 101. The device of the present invention can assemble the inner shell 102 and the outer shell 101, and the spring 103 is in a compressed state after the inner shell 102 and the outer shell 101 are assembled. Example

[0028] like Figure 1An example of an inner and outer shell assembly device is shown, including an outer shell carrier 10, a guide pin assembly 20, an inner shell carrier 30, a pushing assembly 40, a translation assembly 50, a support frame 70, and an auxiliary limiting assembly 60 disposed on the support frame 70, all mounted on a worktable 80. The guide pin assembly 20 is disposed on the side of the outer shell carrier 10 away from the inner shell carrier 30, and the pushing assembly 40 is disposed on the side of the inner shell carrier 30 away from the outer shell carrier 10. The guide pin assembly 20 is slidably disposed on the worktable 80 and can move relatively closer to or further away from the outer shell carrier 10. Both the pushing assembly 40 and the inner shell carrier 30 are disposed on the translation assembly 50 and can move horizontally relative to the worktable 80 via the translation assembly 50. The pushing assembly 40 is slidably disposed on the translation assembly 50 and can move horizontally relative to the inner shell carrier 30. The support frame 70 is fixed on the worktable 80, and the auxiliary limiting assembly 60 can move vertically relative to either the inner shell carrier 30 or the outer shell carrier 10.

[0029] See Figures 1 to 9 The assembly steps for the inner and outer shells are as follows: Figure 9 The outer shell 101 is placed on the outer shell carrier 10, and the inner shell 102 is placed on the inner shell carrier 30. The guide pin 21 moves through the outer shell 101 toward the inner shell 102. The inner shell carrier 30 and the push assembly 40 are driven by the translation assembly 50 to approach the outer shell carrier 10. The push rod 41 of the push assembly 40 abuts against the end of the inner shell 102 away from the outer shell 101, while the push rod 42 of the push assembly 40 abuts against the push rod 22 of the guide pin assembly 20. The driving component of the push assembly 40 drives the push rod 41 to push the inner shell 102 to move, while the push rod 42 pushes the push rod 22 to move. Because the push rod 42 and the guide pin 21 are both fixed on the moving plate 24 of the guide pin assembly 20, the guide pin 21 is moved away from the outer shell 101. The spring 103, which was originally mounted on the guide pin 21, is fitted onto the inner shell 102 at one end, and its length is gradually compressed as the inner shell 102 moves toward the outer shell 101. During the process of the push assembly 40 pushing the guide pin assembly 20, the auxiliary limiting assembly 60 restricts the vertical movement of the inner shell 102 and the outer shell 101.

[0030] The structure of each part will be described in detail below with reference to the attached diagram.

[0031] See Figure 2 , Figure 3 , Figure 4The outer casing carrier 10 is fixedly mounted on the worktable 80. The outer casing carrier 10 has a limiting groove 11 for placing the outer casing 101. A blocking portion 111 is located on the side of the limiting groove 11 away from the inner casing carrier 30. The limiting groove 11 restricts the position of the outer casing 101, ensuring that one end of the outer casing 101 faces the inner casing carrier 30, while the other end is limited by the blocking portion 111. Furthermore, the limiting groove 11 restricts the outer casing 101 to two other horizontal positions, preventing movement. The blocking portion 111 ensures that the outer casing 101 will not retract during assembly of the inner casing 102 and the outer casing 101. The limiting groove 11 can be a groove machined on the outer casing carrier 10 through machining, or it can be formed by one or more independent parts fixed to the outer casing carrier 10. A guide pin assembly 20 is slidably mounted on the side of the outer casing carrier 10 away from the inner casing carrier 30. A portion of the structure of the guide pin assembly 20 can be relatively close to or away from the outer casing carrier 10. The guide pin assembly 20 includes a guide pin 21, a push rod 22, an elastic element 23, and a movable plate 24. One end of the guide pin 21 and the push rod 22 are fixedly connected to the movable plate 24, and the other ends both face the outer casing carrier 10. The movable plate 24 has two slide rails below it, which are located on the upper surfaces of two support plates 71 vertically fixed to the worktable 80. A slider is fixed to the side of the movable plate 24 facing the slide rails, and the slider cooperates with the slide rails to allow the movable plate 24 to slide towards and away from the outer casing carrier 10. A positioning element 26 is provided on the worktable 80 between the two support plates 71, and the positioning element 26 is fixedly connected to the outer casing carrier 10. One end of the elastic element 23 is connected to the movable plate 24, and the other end is connected to the positioning element 26. The elastic element 23 drives the movable plate 24 to move towards the outer casing carrier 10. A connector 27 is mounted on the same surface as the slider on the movable plate 24. The connector 27 is detachably connected to the end of the extension rod of the limiting cylinder 25 fixed on the worktable 80. When the extension rod of the limiting cylinder 25 extends, the connector 27 briefly separates from the extension rod, and the elastic element 23 drives the movable plate 24 to move towards the housing carrier 10. When the extension rod retracts, the extension rod connects with the connector 27, driving the movable plate 24 to move away from the housing carrier 10. This design can limit the distance of the movable plate 24 away from the housing carrier 10 when the extension rod of the limiting cylinder 25 retracts, or limit the movable plate 24 to a certain distance away from the housing carrier 10, and allow the movable plate 24 to move towards the housing carrier 10 a certain distance when the extension rod of the limiting cylinder 25 extends.

[0032] The aforementioned elastic element 23 can be a tension spring, a spring, or other elastic components. One end of the elastic element 23 is connected to the movable plate 24, and the other end is connected to the positioning element 26, giving the elastic element 23 a tendency to drive the movable plate 24 towards the housing carrier 10. For example, when a tension spring is used, the positioning element 26 is fixed between the movable plate 24 and the housing carrier 10; when a spring is used, the positioning element 26 is fixed on the side of the movable plate 24 away from the housing carrier 10. Another way to drive the movable plate 24 is to replace the elastic element 23 and the limiting cylinder 25 with an electric cylinder.

[0033] An inner shell carrier 30 and a pushing assembly 40 are provided on the side of the outer shell carrier 10 away from the guide pin assembly 20. Both the inner shell carrier 30 and the pushing assembly 40 are mounted on a translation plate 51, which is slidably positioned between the translation plate 51 and the worktable 80. The sliding mechanism can be a combination of a slide rail, a slider assembly, and a translation cylinder, or it can be another mechanism with translation drive and guiding structure, such as a slide cylinder. The inner shell carrier 30 has a guide groove 31, in which the inner shell 102 is placed. The guide groove 31 also has a stop 311, which is located at the end of the guide groove 31 away from the outer shell carrier 10. The stop 311 restricts the movement of the inner shell 102 on the guide groove 31 towards the side away from the outer shell carrier 10, preventing the inner shell 102 from falling out of the inner shell carrier 30 as it moves towards the outer shell carrier 10. The jacking assembly 40 is located on the side of the inner shell carrier 30 away from the outer shell carrier 10. The jacking assembly 40 includes a jacking rod 41, a first jacking rod 42, a second movable plate 43, and a jacking electric cylinder 44. The jacking rod 41 and the first jacking rod 42 are fixedly connected to the second movable plate 43. The second movable plate 43 is slidably disposed relative to the translation plate 51. The second movable plate 43 is driven and connected by the jacking electric cylinder 44, which can drive the second movable plate 43 to move relative to the translation plate 51. The translation cylinder 52 can push the translation plate 51 closer to the outer shell carrier 10. The inner shell carrier 30 and the jacking assembly 40 are jointly driven to move closer to the outer shell carrier 10. After the translation plate 51 moves into place, the inner shell carrier 30 docks with the outer shell carrier 10, and the inner shell 102 on the inner shell carrier 30 and the outer shell 101 on the outer shell carrier 10 are aligned along their assembly direction. The push rod 41 of the push assembly 40 is aligned with the inner shell carrier 30. Driven by the push electric cylinder 44, the push rod 41 can push the inner shell 102 to move on the guide groove 30. The extension direction of the guide groove 30 is consistent with the assembly direction of the inner shell 102 and the outer shell 101, which can make the inner shell 102 be correctly pushed to assemble with the outer shell 101.

[0034] When the push rod 41 pushes the inner shell 102, push rod one 42 engages with push rod two 22. Driven by the push rod electric cylinder 44, push rod one 42 pushes push rod two 22, causing the guide pin 21 to move away from the outer shell carrier 10. In this way, more and more springs 103 are fitted onto the spring-installed structure inside the inner shell 102, realizing the gradual movement of the inner shell 102 towards the outer shell 101, while the guide pin 21 simultaneously retracts from the outer shell 101. The push rod electric cylinder 44 can be a combination of slide rail, slider and cylinder or a slide table cylinder; these guiding and driving mechanisms are all acceptable.

[0035] See Figure 1 , Figure 5 A support frame 70 is mounted on a workbench 80. The support frame 70 includes a support plate 71 and a support column 72. The support plate 71 is connected to the workbench 80 via the support column 72. The auxiliary limiting assembly 60 includes a lifting plate 62 and an auxiliary component 61. The lifting plate 60 can move closer to and further away from the outer casing carrier 10 in a vertical direction via a lifting mechanism. The lifting mechanism includes a combination of a guide rod 63, a sliding bearing 64, and a lifting cylinder 65. One end of the guide rod 63 is connected to the lifting plate 62, and the other end passes through the sliding bearing 64. Both the sliding bearing 64 and the lifting cylinder 65 are fixedly mounted on the support plate 71. The extension rod of the lifting cylinder 65 is connected to the lifting plate 62, which can drive the lifting plate 62 closer to or further away from the outer casing carrier 10. The lowering of the lifting plate 62 causes the auxiliary component 61, mounted on its side near the outer casing 10, to move closer to the inner casing 102 and the outer casing 101. This provides vertical restraint to the inner casing 102, outer casing 101, and spring 103 from above, further ensuring smooth assembly of the inner casing 102 and outer casing 101. The lifting mechanism can also be replaced by other driving components such as a sliding cylinder or a cylinder with a guide rod.

[0036] Furthermore, to facilitate the loading of the outer casing 101, a movable plate 73 is provided between the support plate 71 and the lifting mechanism. The lifting cylinder 65 and the sliding bearing 64 of the lifting mechanism are both mounted on the movable plate 73. The movable plate 73 is slidably mounted relative to the support plate 71 via a slide rail and a slider assembly. The support plate 71 is equipped with a movable cylinder 74, which drives the movable plate 73 to move, thereby driving the auxiliary limiting assembly 60 to move away from directly above the outer casing carrier 10.

[0037] It should be noted that in the above structure, there can be multiple push rods 41, guide grooves 31, limiting grooves 11, guide pins 21, and auxiliary components 61. The number can be selected according to the design requirements. Multiple push rods 41, guide grooves 31, limiting grooves 11, guide pins 21, and auxiliary components 61 are arranged in a direction perpendicular to the moving direction of push rods 41.

[0038] The process steps involved in this embodiment are as follows: 1. Place the outer casing 101 horizontally on the limiting groove 11 of the outer casing carrier 10; 2. The guide pin 21 moves from one side of the housing carrier 10 toward the housing 101, and the guide pin 21 passes through the hollow part in the horizontal direction of the housing 101; 3. Spring 103 is fitted onto guide pin 21, so that part of guide pin 21 passes through spring 103; 4. Place the inner shell 102 horizontally on the guide groove 31 of the inner shell carrier 30; 5. The inner shell carrier 30 is close to the outer shell carrier 10, so that the inner shell 102 and the outer shell 101 are aligned in the same straight line, and one end of the inner shell 102 is close to the guide pin 21, so that the structure of the inner shell 102 that installs the spring 103 is connected to the guide pin 21. 6. The auxiliary component 61 descends and approaches the outer shell carrier 10, restricting the spring 103, inner shell 102 and outer shell 101 in the height direction.

[0039] 7. The push rod 41 pushes the inner shell 102 to move along the guide groove 31 toward the outer shell 101, and synchronously drives the guide pin 21 to exit the outer shell 101 until the assembly is completed and the movement of the guide pin 21 is restricted.

[0040] 8. After assembly, the push rod 41 and the inner shell carrier 30 are reset, and the auxiliary component 61 is reset.

[0041] It should be noted that the action of putting the spring 103 onto the guide needle 21 can be done manually or by an automated mechanism. Either method is acceptable as long as the spring 103 is put onto the guide needle 21 after the guide needle 21 passes through the hollow part of the outer shell 101.

[0042] It should be noted that the various technical features in the above embodiments are organically combined to achieve the assembly action or to improve the assembly effect. The paragraphs are only for easier explanation of the details, and are not because the technical features in each paragraph are independent and unrelated. Example

[0043] Another example of an inner and outer shell assembly device, which differs from Embodiment 1 in that the outer shell carrier 10 and the guide pin assembly 20 are mounted on a turntable 90, which is mounted on a worktable 80. The rotation of the turntable 90 drives the outer shell carrier 10 to align with the position of the inner shell carrier 30.

[0044] See Figure 7 , Figure 8The simplified limiting cylinder uses a limiting pin 91 to limit the movement of the moving plate 24. The limiting pin 91 is set on the turntable 90 and can slide up and down relative to the turntable 90. A spring is set between the limiting pin 91 and the turntable 90. One end of the spring abuts against the limiting pin 91 and the other end abuts against the turntable 90. Under the action of the spring, the limiting pin 91 has an upward sliding tendency. The end of the limiting pin 91 located below the turntable 90 has a convex ring. The function of the convex ring is to prevent the spring from popping the entire limiting pin 91 out. The convex ring has a pin-moving space. A pin-moving plate 94 can extend into the pin-moving space. Driven by the pin-moving cylinder, the pin-moving plate 94 can drive the limiting pin 91 to move up and down.

[0045] After the outer shell 101 is loaded, the pin-pulling cylinder drives the lever 94 to lower the limiting pin 91, releasing the limiting of the connector 27. The elastic element 23 drives the moving plate 24 to move towards the outer shell carrier 10, inserting the guide pin 21 through the hollow part of the outer shell 101. During the process of the turntable 90 rotating the outer shell carrier 10 to the corresponding position of the inner shell carrier 30, or when the pin-pulling cylinder retracts, the limiting pin 91 disengages from the lever 94 and elastically extends again. After the inner shell 102 is assembled into the outer shell 101, the guide pin assembly 20 is driven by the push assembly 40 to completely remove the guide pin 21 from the outer shell 101. The connector 27 is then restricted by the limiting pin 91 again, preventing the guide pin assembly 20 from approaching the outer shell carrier 10. The process of the limiting pin 91 restricting the connector 27 here can be such that both sides of the connector 27 and the limiting pin 91 have inclined surfaces, such as... Figure 9 The connector 27 moves through the ramp, causing the limiting pin 91 to descend until the planes of the two are about to come into contact. The connector 27 is then restricted by the limiting pin 91 to move toward the outer casing carrier 10.

[0046] The process steps involved in this embodiment are as follows: 1. Place the outer casing 101 horizontally on the limiting groove 11 of the outer casing carrier 10; 2. The guide pin 21 moves from one side of the housing carrier 10 toward the housing 101, and the guide pin 21 passes through the hollow part in the horizontal direction of the housing 101; 3. Spring 103 is fitted onto guide pin 21, so that part of guide pin 21 passes through spring 103; 4.
