DETAILED DESCRIPTION

[0020] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 4 As shown, this embodiment provides a device for assembling a trocar gas injection valve, comprising: a rotating table 1 suitable for rotary motion, five stations arranged on the rotating table 1 at intervals along the circumferential direction, and a gas injection valve feeding assembly, a silicone oil atomizing lubrication assembly, a gas injection valve switch feeding assembly, a press-fitting assembly, and a dispensing and unloading assembly arranged one-to-one in the five stations in the circumferential direction of the rotating table 1. A fixing seat 2 for positioning the main steam valve is provided on each station.

[0022] Based on the above situation, generally speaking, the gas injection valve feeding assembly includes a first vibration plate 6 carrying the gas injection valve 3 and a first transfer group for transferring the gas injection valve 3 from the first vibration plate 6 to the corresponding station; the silicone oil atomization lubrication assembly includes a silicone oil atomizer 4 and a first lifting driver 8 for driving the silicone oil atomizer 4 to perform lifting and lowering movements. It is necessary to explain here that, with respect to the silicone oil atomizer 4 of this embodiment, it is also connected to a silicone oil introduction chamber and a driving assembly for introducing silicone oil into the silicone oil introduction chamber. For the silicone oil introduction chamber and the driving assembly here, any mature means in the prior art can be selected, such as but not limited to the technical solution disclosed in the announcement number CN221387051U. The silicone oil introduction chamber and the driving assembly here are not improved in this embodiment, so their structure is not absolutely limited. For the first vibration plate 6 and the second vibration plate to realize feeding, and for the specific structure and implementation principle of the first vibration plate 6 and the second vibration plate, any mature means in the prior art can be selected, and this embodiment does not make an absolute limitation on this.

[0023] The gas injection valve switch loading assembly includes a second vibration plate for carrying the gas injection valve switch 5 and a second transfer group for transferring the gas injection valve switch 5 from the second vibration plate to the corresponding workstation; the press-fitting assembly includes a die 10 and a second lifting drive 9 for driving the die 10 to perform lifting and lowering movements; the glue dispensing and unloading assembly includes a third transfer group for moving the assembly parts on which the gas injection valve switch 5 and the gas injection valve 3 are pressed from the corresponding workstation, and a glue dispensing group for gluing the assembly parts on the second transfer group.

[0024] Next, an optional implementation is given as an example with reference to the accompanying drawings: First, the first lifting drive 8 and the second lifting drive 9 both use driving cylinders. The dispensing group includes a dispensing stick 11 and a first cylinder 14 for driving the dispensing stick 11 to move closer to and away from the third transfer group. The clamping needle group includes a pin 12 suitable for being inserted into the gas injection valve 3 and a second cylinder 13 for driving the pin 12 to move linearly.

[0025] Secondly, the first transfer group includes a first pneumatic clamp 15 for clamping the gas injection valve 3 and a first two-axis mobile drive assembly 7 connected to the first pneumatic clamp 15. The second transfer group includes a second pneumatic clamp 16 for clamping the gas injection valve switch 5 and a second two-axis mobile drive assembly connected to the second pneumatic clamp 16. The third transfer group includes a clamping needle group for fixing the assembly and a third two-axis mobile drive assembly 27 connected to the clamping needle group.

[0026] On the basis of the above structure, it is necessary to further explain that the first two-axis mobile drive assembly 7, the second two-axis mobile drive assembly and the third two-axis mobile drive assembly 27 adopt the same two-axis mobile drive structure.

[0027] Furthermore, the two-axis moving driving structure includes a connecting rod 17, a sliding block 18 connected to the connecting rod 17, a slide rail 19 slidably matched with the sliding block 18, and a power structure for driving the sliding block to move; wherein the slide rail 19 is prefabricated in the support seat 28; the slide rail 19 is a U-shaped structure; and the power structure includes a pull rod 23 connected to the sliding block, and a driving motor 20 for driving the pull rod 23 to rotate. The U-shaped opening of the U-shaped slide rail 19 faces the pull rod 23. The connecting rod 17 can drive the first pneumatic clamp 15, the second clamp and the clamping needle group to move in combination with the requirements of different two-axis moving driving components.

[0028] Regarding the pull rod 23 used in this embodiment, it should be specifically explained that a rotating shaft 21 connected to one end of the pull rod 23 is provided at the position of the support seat 28 corresponding to the middle of the slide rail 19 of the U-shaped structure, and the driving motor 20 is connected to the rotating shaft 21 to drive the rotating shaft 21 to rotate. The slider is slidably matched with the slide rail 19 through a movable column 22, and the end of the pull rod 23 away from the rotating shaft 21 is connected to the movable column 22, and the pull rod 23 is provided with a waist-shaped through hole 24 for being sleeved on the movable column 22. More specifically, taking the movable column 22 as a cylindrical structure as an example, the outer diameter of the movable column 22 is preferably adapted to the short axis inner diameter of the waist-shaped through hole 24, but the outer diameter of the movable column 22 is much smaller than the long axis inner diameter of the waist-shaped through hole 24, so that the rotational movement of the pull rod 23 can be converted into the slider first making a linear sub-longitudinal movement along the slide rail 19, and then making a linear lateral movement along the slide rail 19, or the rotational movement of the pull rod 23 can be converted into the slider first making a linear lateral movement along the slide rail 19, and then making a linear longitudinal movement along the slide rail 19.

[0029] On the basis of the above structure, for example, the initial position of the slider is in one of the tracks of the U-shaped slide rail 19 parallel to the pull rod 23. When the pull rod 23 rotates under the action of the drive motor 20, the slider will first move up along the track of the slide rail 19 parallel to the pull rod 23, and then move to the track of the slide rail 19 perpendicular to the pull rod 23. Under this structure, for the pull rod 23, it first moves up and then moves horizontally, thereby realizing the movement trajectory of the pull rod 23 in two different dimensions. During the movement of the slider along the slide rail 19, the pull rod 23 is always kept in only longitudinal and lateral translation without flipping.

[0030] In addition, it should be noted that the support seat 28 is also provided with a limit block 25 that is slidably matched with the connecting rod 17; and the limit block 25 is slidably matched with the support seat 28; the limit block 25 is suitable for moving in the support seat 28 along a direction perpendicular to the connecting rod 17. A guide track 26 is provided on the support seat 28 that is perpendicular to the direction of the connecting rod 17 and is adapted to the limit block 25.

[0031] In summary, for the device for assembling the trocar gas injection valve of this embodiment: The gas injection valve loading assembly is used to deliver the gas injection valve 3 to be pressed to the work station, so that it can be sent to the silicone oil atomization lubrication assembly through the rotation of the rotary table 1 for silicone oil atomization lubrication operation. The gas injection valve switch loading assembly is used to deliver the gas injection valve switch 5 to the gas injection valve 3 that has completed silicone oil atomization lubrication. The press-fitting assembly is used to press-fit the gas injection valve 3 and the gas injection valve switch 5, so that the two form a reliable assembly. The glue dispensing unloading assembly is used to dispense glue on the assembly formed by the press-fitting of the gas injection valve 3 and the gas injection valve switch 5, and after the glue dispensing is completed, it is rotated out of the rotary table 1, so that the glued assembly can be manually loaded directly into the sleeve of the puncture device. Therefore, for the assembly process of the whole gas injection valve 3 and the sleeve of the puncture device, the manual operation only needs to remove the gas injection valve switch 5 and the gas injection valve 3 with glue applied from the pin 12 in the glue dispensing and unloading assembly and directly install it into the sleeve. Therefore, compared with the manual operation method, it not only improves the assembly operation efficiency, but also avoids the problem that the manual operation is greatly affected by the operating experience, that is, optimizes the assembly effect. In other words, the overall operation process work efficiency is greatly improved, auxiliary time is saved, labor intensity is reduced, the experience and quality requirements of the operator are reduced, and the assembly accuracy is good, the product quality is stable, and the yield rate is greatly improved.
