Description

Technical Field

[0001] This invention relates to the field of laparoscopic puncture technology, specifically to a disposable laparoscopic puncture device assembly machine. Background Technology

[0002] A laparoscopic trocar is a tool used during laparoscopic examinations and surgeries to puncture the abdominal wall tissue and establish a working channel for abdominal surgery. It is made of special materials to ensure a smooth channel, allowing instruments to enter and exit smoothly and increasing the flexibility of the surgery. Disposable laparoscopic trocars are for single use only, which can avoid the risk of cross-infection. Currently, disposable laparoscopic trocars require an assembly machine for assembly.

[0003] Currently, there are many types of assembly machines used for disposable laparoscopic trocars on the market, but certain problems still exist. First, existing assembly machines require manual feeding, which is time-consuming, labor-intensive, and cumbersome. It is also difficult to achieve alternating feeding and positioning. Furthermore, it is not possible to directly feed the materials to the UV baking line for automatic baking, which reduces the assembly efficiency of disposable laparoscopic trocars and increases the labor intensity during assembly. Summary of the Invention

[0004] The purpose of this invention is to provide a disposable laparoscopic trocar assembly machine to solve the problems mentioned in the background art, such as the need for manual feeding of materials, which is time-consuming and labor-intensive, and the inability to directly feed materials to the UV baking line for automatic baking, resulting in low assembly efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The structure of the disposable laparoscopic trocar assembly machine provided by the present invention is as follows: Figure 1 As shown, it includes a left frame 1 and a right frame 2 fixedly connected to one side of the left frame 1. The top of the left frame 1 is fixed with a left guard frame 101 for safety protection, and the left guard frame 101 is fixedly connected to the connecting arm connected to the control panel 102. The top of the right frame 2 is equipped with a right guard frame 201, and the front side of the right guard frame 201 is provided with a feeding port for discharging materials.

[0026] Furthermore, such as Figure 2 As shown, a first rotating disk 3 is provided on one side of the top of the left frame 1, and a second rotating disk 4 is provided on the surface of the left frame 1 away from the first disk 3. The surfaces of the second disk 4 and the first disk 3 are each provided with eight workstations. At the same time, the first disk 3 and the second disk 4 are transported by the outer pin assembly mechanism 14 to the piercing outer pin assembly on the surface of the second disk 4, so that it is combined with the piercing sealing cap assembly on the surface of the first disk 3.

[0027] During implementation, the assembly mechanism 14 automatically loads the combination of the puncture outer sheath, the air injection valve, and the 5mm V-shaped sealing ring onto the combination of the puncture sealing cap, the multi-lobed sealing ring, and the four-groove sealing ring at the first disc 3 station.

[0028] Furthermore, such as Figure 6 , Figure 7 as well as Figure 8 As shown, on the surface of the left frame 1 and outside the first disc 3, there are respectively a sealing cap feeding mechanism 5, a multi-lobed sealing ring assembly mechanism 6, a four-groove sealing ring assembly mechanism 7, an automatic dispensing mechanism 8, a sealing cap visual positioning mechanism 9, an outer pin pressing mechanism 10, a robotic arm automatic unloading mechanism 17, and a UV baking mechanism 18. Among them, the outer pin pressing mechanism 10 is used to press the assembly of the piercing large outer sheath, the air injection valve, and the 5mm V-shaped sealing ring with the assembly of the piercing sealing cap, the multi-lobed sealing ring, and the four-groove sealing ring. The robotic arm automatic unloading mechanism 17 is used to automatically unload the pressed assembly. The UV baking mechanism 18 is used for UV baking. On the surface of the left frame 1 and outside the second disc 4, there are respectively a gas injection valve automatic feeding mechanism 12, a gas injection valve assembly mechanism 13, a gas injection valve dispensing mechanism 15, and a sealing ring feeding mechanism 16.

[0029] During implementation, the puncture sealing cap is automatically fed onto the tooling at the first disc 3 station by the sealing cap feeding mechanism 5. After feeding, the multi-lobed sealing ring is automatically fed into the puncture sealing cap by the multi-lobed sealing ring assembly mechanism 6 and assembled. Then, the 5mm four-groove sealing ring is automatically fed into the combination of the puncture sealing cap and the multi-lobed sealing ring by the four-groove sealing ring assembly mechanism 7 and assembled. Subsequently, UV glue is automatically applied to the positioning post of the sealing cap by the action of the second disc 4. During this process, the first disc 3 station is rotated by the stepper motor at the bottom of the first disc 3.

[0030] Furthermore, such as Figure 4 As shown, the sealing cap visual positioning mechanism 9 is used for visual inspection of the punctured sealing cap after it is loaded. The sealing cap visual positioning mechanism 9 consists of a support slide 91, a sliding crossbar 92 and a camera 93. The support slide 91 is installed on the surface of the left frame 1, and the sliding crossbar 92 is slidably connected to the surface of the support slide 91. The sliding crossbar 92 and the support slide 91 are fixedly connected to each other by bolts, and one end of the sliding crossbar 92 is detachably connected to a camera 93 for visual positioning.

[0031] Furthermore, such as Figure 6 As shown, the outer pin pressing mechanism 10 is used for pressing the piercing outer pin assembly and the piercing sealing cap assembly. The outer pin pressing mechanism 10 includes a mechanism frame 1001, a pressing cylinder 1002, and a pressing block 1003. The mechanism frame 1001 is installed on the surface of the left frame 1 by four bolts, and the pressing cylinder 1002 is fixed at the top of the mechanism frame 1001. The output end of the pressing cylinder 1002 passes through the mechanism frame 1001 and is equipped with the pressing block 1003 for pressing.

[0032] Furthermore, such as Figure 5 As shown, an outboard pin feeding mechanism 11 for feeding outboard pins is installed on the surface of the right frame 2. The outboard pin feeding mechanism 11 is used for feeding pierced large outboard pins. The outboard pin feeding mechanism 11 contains, in sequence, a small disc 111, a moving module housing 112, a stationary module housing 113, a U-shaped frame 114, a linear module 115, and a material support plate 116. The small disc 111 is rotatably connected to the surface of the right frame 2. A stationary module housing 113 is fixedly connected to one side of the surface of the right frame 2 via a bracket. The stationary module housing 113 is connected to a slidable movable module housing 112 on one side, and the movable module housing 112 is driven by a cylinder. A U-shaped frame 114 for feeding is installed in the middle of the right frame 2, and a linear module 115 is installed on the other side of the left frame 1 and on one side of the U-shaped frame 114. A material support plate 116 is provided on one side of the linear module 115, and the material support plate 116 is fixedly connected to the surface of the right frame 2 by a support leg.

[0033] During implementation, the 5mm V-shaped sealing ring is automatically loaded into the tooling at the second disc 4 station via the sealing ring feeding mechanism 16, and the 5mm puncture outer sheath is automatically loaded into the corresponding tooling with the V-shaped sealing ring via the outer pin feeding mechanism 11. During this process, the stepper motor at the bottom of the second disc 4 drives the second disc 4 to rotate, thereby driving the rotation of the station.

[0034] Furthermore, such as Figure 3 As shown, the sealing cap feeding mechanism 5, the multi-lobed sealing ring assembly mechanism 6, the four-groove sealing ring assembly mechanism 7, the automatic dispensing mechanism 8, the automatic air injection valve feeding mechanism 12, the air injection valve assembly mechanism 13, the external pin assembly mechanism 14, the air injection valve dispensing mechanism 15, the sealing ring feeding mechanism 16, the robotic arm automatic unloading mechanism 17, and the UV baking mechanism 18 are all fixedly connected to the surface of the left frame 1 by multiple bolts, and the first disc 3, the second disc 4, and the small disc 111 are all driven by stepper motors to rotate.

[0035] Furthermore, such as Figure 2 As shown, a retractable and rotatable control panel 102 is provided on one side of the left frame 1 via a connecting arm. The control panel 102 is electrically connected to the sealing cap feeding mechanism 5, the multi-lobed sealing ring assembly mechanism 6, the four-groove sealing ring assembly mechanism 7, the automatic dispensing mechanism 8, the sealing cap visual positioning mechanism 9, the outer pin pressing mechanism 10, the outer pin feeding mechanism 11, the automatic air injection valve feeding mechanism 12, the air injection valve assembly mechanism 13, the outer pin assembly mechanism 14, the air injection valve glue dispensing mechanism 15, the sealing ring feeding mechanism 16, the robotic arm automatic unloading mechanism 17, and the UV baking mechanism 18. Each of the following structures—structure 5, multi-lobed sealing ring assembly mechanism 6, four-groove sealing ring assembly mechanism 7, automatic air injection valve feeding mechanism 12, and sealing ring feeding mechanism 16—is equipped with a feeding vibratory feeder 103 for feeding materials. The input end of the feeding vibratory feeder 103 is electrically connected to the output end of the control panel 102. The feeding vibratory feeders 103 on one side of the sealing cap feeding mechanism 5, multi-lobed sealing ring assembly mechanism 6, four-groove sealing ring assembly mechanism 7, automatic air injection valve feeding mechanism 12, and sealing ring feeding mechanism 16 are respectively used for feeding materials such as piercing sealing caps, multi-lobed sealing rings, four-groove sealing rings, air injection valves, and V-shaped sealing rings.

[0036] During implementation, the automatic feeding mechanism 12 for the air injection valve is used to automatically feed the air injection valve. After the air injection valve is automatically fed, the UV glue is applied to the air injection valve by the glue application mechanism 15. After the UV glue is applied, the stepper motor at the bottom of the second disc 4 drives the second disc 4 to rotate to the position of the air injection valve assembly mechanism 13 that combines the 5mm V-shaped sealing ring and the 5mm puncture outer sheath. The air injection valve assembly mechanism 13 then automatically inserts the UV glue-applied air injection valve into the puncture outer sheath.

[0037] Working principle: During use, the puncture sealing cap is automatically fed onto the tooling at the first disc 3 station by the sealing cap feeding mechanism 5. After feeding, the multi-lobed sealing ring is automatically fed into the puncture sealing cap by the multi-lobed sealing ring assembly mechanism 6 and assembled. Then, the four-groove sealing ring assembly mechanism 7 automatically feeds the 5mm four-groove sealing ring into the combination of the puncture sealing cap and the multi-lobed sealing ring and assembles it. Subsequently, UV glue is automatically applied to the positioning post of the sealing cap by the action of the second disc 4. During this process, the stepper motor at the bottom of the first disc 3 drives the station of the first disc 3 to rotate.

[0038] Subsequently, the 5mm V-shaped sealing ring is automatically loaded into the fixture at the second disc 4 station via the sealing ring feeding mechanism 16. Then, the 5mm puncture outer sheath is automatically loaded into the corresponding fixture with the V-shaped sealing ring via the outer pin feeding mechanism 11. During this process, the stepper motor at the bottom of the second disc 4 drives the second disc 4 to rotate, thereby driving the rotation of the station.

[0039] Then, the automatic feeding mechanism 12 for the air injection valve is used to automatically feed the air injection valve. After the air injection valve is automatically fed, the UV glue is applied to the air injection valve by the glue application mechanism 15. After the UV glue is applied, the stepper motor at the bottom of the second disc 4 drives the second disc 4 to rotate to the position of the air injection valve assembly mechanism 13 that combines the 5mm V-shaped sealing ring and the 5mm puncture outer sheath. The air injection valve assembly mechanism 13 then automatically inserts the air injection valve with the UV glue into the puncture outer sheath.

[0040] Finally, the outer pin assembly mechanism 14 automatically installs the combination of the puncture outer sheath, the air injection valve, and the 5mm V-shaped sealing ring onto the combination of the puncture sealing cap, the multi-lobed sealing ring, and the four-groove sealing ring at the first disc station 3. Then, the outer pin pressing mechanism 10 presses the two assemblies together. After that, the robotic arm automatic unloading mechanism 17 automatically unloads the pressed assemblies. Then, the UV baking mechanism 18 performs UV baking, and finally the assembly of the disposable laparoscopic puncture device is completed.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
