Key drawbacks include low assembly efficiency, fatigue and errors, and difficulty controlling the amount of glue and silicone oil used. Currently, trocar assembly equipment has achieved automated assembly of some functions, but due to the inability to automatically install certain features, fully automated trocar assembly remains elusive.

DETAILED DESCRIPTION

[0021] The utility model is described in detail below with reference to the accompanying drawings:

[0022] like Figure 1-2The figure shows a V-shaped air-blocking valve feeding mechanism for trocar assembly, characterized in that it is installed on one side of the trocar assembly line and used in conjunction with the transmission line of the trocar assembly line to complete the feeding of the V-shaped air-blocking valve of the trocar;

[0023] include

[0024] The air-blocking valve vibration plate 1 is located outside the trocar assembly line and is used to store and output the air-blocking valve;

[0025] The frame 2 is located between the air blocking valve vibration plate 1 and the trocar assembly line;

[0026] The receiving profiling jig 3 is located at the discharge port of the choke valve vibration plate 1 and is installed on the frame, and is used to receive the choke valve vibration plate output by the choke valve vibration plate 1;

[0027] The steering profiling jig 4 is located between the profiling jig 3 and the puncture device assembly line and is rotatably mounted on the frame. A choke valve rotary cylinder module 41 is provided at the bottom of the frame, and the choke valve rotary cylinder module 41 is connected to the steering profiling jig 4 and drives the steering profiling jig 4 to steer;

[0028] The choke valve cylinder transplanting module 5 is located on the side of the receiving profiling jig 3 and the steering profiling jig 4 and is fixedly connected to the frame 2;

[0029] The choke valve lifting cylinder module 6 is slidably connected to the choke valve cylinder transfer module 5 and is located above the receiving profiling jig 3 and the steering profiling jig 4; the choke valve cylinder transfer module 5 drives the choke valve lifting cylinder module 6 to move forward and backward; and

[0030] The suction cup assembly includes a suction cup bracket 71 and an inner suction cup 72 and an outer suction cup 73 respectively provided on the bottom surface of the suction cup bracket 71. The suction cup bracket 71 is connected to the output end of the choke valve lifting cylinder module 6. A negative pressure mechanism 74 is installed on the side of the choke valve lifting cylinder module 6. The inner suction cup 72 and the outer suction cup 73 are both connected to the negative pressure mechanism 74 through pipelines.

[0031] Among them, when the connecting line of the receiving profiling jig 3, the steering profiling jig 4 and the puncture device mounting jig of the transmission line is a straight line in the front and rear directions, the distance between the inner suction cup 72 and the outer suction cup 73, the distance between the receiving profiling jig 3 and the steering profiling jig 4, and the distance between the steering profiling jig 4 and the puncture device mounting jig are all the same.

[0032] Currently, the assembly of puncture devices is carried out in an assembly line manner, and the installation or processing of each process of the puncture device is completed through a circular or linear assembly line, thereby completing the processing of the puncture device. The puncture device here is installed on the puncture device installation fixture arranged in sequence on the assembly line.

[0033] The utility model mainly completes the installation of the V-shaped air-blocking valve in the puncture assembly line operation; it should be noted that the V-shaped air-blocking valve structure includes an annular gasket and a cross-section arranged in the annular gasket with a V-shaped air-blocking structure.

[0034] The choke valve vibrating disk 1 is currently purchased directly and installed on one side of the assembly line. It is mainly used to store and output the choke valve. There is a certain distance between the choke valve vibrating disk 1 and the assembly line, so it needs to be transferred through components such as a receiving profiling jig, a steering profiling jig, and a suction cup assembly. In order to facilitate the suction cup assembly to grab a specific choke valve, a receiving profiling jig is set up, and the choke valve of the choke valve vibrating disk falls into the receiving profiling jig. In addition, because the choke valve needs to be turned before being installed on the puncture device, a steering profiling jig 4 is also required to realize the steering of the choke valve.

[0035] In addition, when the connecting line of the receiving profiling jig 3, the steering profiling jig 4 and the puncture device mounting jig of the transmission line is a straight line in the front and rear directions, the distance between the inner suction cup 72 and the outer suction cup 73, the distance between the receiving profiling jig 3 and the steering profiling jig 4, and the distance between the steering profiling jig 4 and the puncture device mounting jig are all the same.

[0036] Based on the above structure, the utility model can complete the following actions. The receiving profiling jig 3 receives the air blocking valve, and then the inner suction cup of the suction cup assembly absorbs the profiling jig 3 to receive the air blocking valve, while the outer suction cup corresponds to the steering profiling jig 4 and absorbs the air blocking valve that has been turned on the steering profiling jig 4; then the suction cup assembly is lifted and moved outward while the steering profiling jig 4 is reset; after the suction cup assembly is moved, the inner suction cup is located above the steering profiling jig 4, and the outer suction cup is located above the puncture device mounting jig of the puncture device. The inner suction cup of the lowered suction cup assembly places the air blocking valve to be turned on the steering profiling jig 4, and the outer suction cup of the suction cup assembly installs the turned air blocking valve on the puncture device.

[0037] The receiving profiling jig 3 is slidably mounted on the frame 2. A jig sliding cylinder module 8 is located below the frame 2. This jig sliding cylinder module 8 is connected to the receiving profiling jig 3 and drives it to move back and forth. Because the outlet of the choke valve vibrating plate 1 and the steering profiling jig 4 are not necessarily aligned in a straight line in the forward and backward directions, the receiving profiling jig 3 is used to achieve distance compensation.

[0038] The receiving profiling fixture 3 is provided with a guide groove 31 having a V-shaped cross section and extending toward the choke valve vibration disk. The guide groove 31 is provided here to ensure that the choke valve falls into the guide groove when the choke valve vibration disk 1 pushes the choke valve forward.

[0039] A gear is coaxially provided at the bottom of the steering profiling jig 4, and a rack is provided at the output end of the choke valve rotary cylinder module. The rack and the gear mesh to control the steering profiling jig 4 to complete a 90° forward or 90° reverse rotation. The transmission method here is conventional technology, so it will not be described in detail.

[0040] A V-shaped limiting groove 42 is provided in the middle of the steering profiling fixture 4. The V-shaped limiting groove 42 mainly plays a role of limiting.

[0041] It should be noted that, in order to ensure the unique accuracy of the choke valve cylinder transplanting module 5, it may be considered to provide a displacement sensor on the choke valve cylinder transplanting module 5 for control.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
