Description

Technical Field

[0001] This utility model belongs to the field of laryngeal mask production technology, specifically relating to an automatic glue dispensing device for the tail end of a laryngeal mask. Background Technology

[0002] The laryngeal mask airway (LMA) is an important medical device widely used in anesthesia and emergency medicine to maintain a patient's airway patency. Its core structure consists of two parts: a ventilation tube 41 and an inflatable cuff 42 (the structure of which is shown in the image). Figure 1 (As shown): One end of the ventilation tube 41 is connected to an anesthesia machine or ventilator, and the other end is fitted with an air bag 42. After the air bag is inflated through the injection tube, it can form a sealed ventilation space in the larynx, ensuring that the gas can smoothly enter the lungs. During the production process, the ventilation tube 41 of the laryngeal mask 4 needs to be assembled with the air bag 42, and glue is applied to the connection points at the head and tail of the air bag to ensure the connection between the air bag and the tube is firm, airtight, and reliable for long-term use. However, the existing glue application process mainly relies on manual operation, which has many shortcomings: First, it is inefficient and cannot meet the needs of large-scale production; second, the consistency of glue application quality is poor and is easily affected by the operator's technical level, experience, and operational standardization. Therefore, it is urgent to develop an efficient automated glue application process to improve the production efficiency and quality stability of laryngeal masks. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic glue dispensing device for the tail end of a laryngeal mask, which can automatically dispense glue to the tail end of the laryngeal mask, thereby reducing manual intervention and improving production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides an automatic dispensing device for the tail end of a laryngeal mask, including a frame, an automatic dispensing mechanism mounted on the frame, a turntable mounted on the frame, and a positioning fixture mounted on the turntable for clamping and positioning the laryngeal mask. The turntable is driven by a motor to rotate intermittently. The automatic dispensing mechanism includes a shifting device, a rotating frame, a rotating drive mechanism, and a dispensing device. The shifting device drives the rotating drive mechanism to perform a moving action, the rotating drive mechanism drives the rotating frame to rotate 360 ​​degrees, and the dispensing device is mounted on the rotating frame.

[0006] Preferably, the rotary drive mechanism includes a motor, and the rotary frame is fixed on the output shaft of the motor; when the motor rotates, it drives the rotary frame to rotate.

[0007] Preferably, the rotating frame has a C-shaped structure, with the upper end of the rotating frame fixedly connected to the rotating drive mechanism and the lower end of the rotating frame fixedly connected to the dispensing device.

[0008] Preferably, the positioning fixture includes a fixed base, a fixed clamping block, a movable clamping block, and a reaction spring; the fixed base is fixed on the turntable, the fixed clamping block is fixed on the fixed base, the movable clamping block is movably mounted on the fixed base and is arranged opposite to the fixed base, and the reaction spring provides elastic force to the movable clamping block, so that the movable clamping block maintains the tendency to move towards the fixed clamping block.

[0009] Preferably, a drive block is fixed on the frame for loading and unloading, and a guide slope is provided on the drive block. A linkage is fixed at the lower end of the movable clamping block. When the linkage rotates to the drive block, it abuts against the linkage through the guide slope to push the movable clamping block to move away from the fixed clamping block.

[0010] Preferably, the linkage has a roller adapted to abut against the guide ramp.

[0011] Preferably, the fixed base is fixed with support blocks at intervals, the support blocks are fixed with limit guide posts, the movable clamping block is provided with guide post sleeve holes, the guide post sleeve holes are sleeved with the limit guide posts, and the reaction spring is sleeved on the limit guide posts.

[0012] Preferably, the fixed clamping block is provided with a contoured protrusion that matches the shape of the head end cavity of the laryngeal mask, and the movable clamping block is provided with a clamping opening facing the fixed clamping block.

[0013] Preferably, the fixed base is equipped with a detection device, which includes a detection fixing member fixed on the fixed base, a detection rod movable up and down on the detection fixing member, and an elastic member sleeved on the detection rod. The elastic member provides an upward elastic force to the detection rod. The lower end of the detection rod is provided with a sensing plate. The frame is provided with a sensor switch. When the throat mask is mounted on the positioning fixture, it applies downward pressure to the detection rod and is adapted to trigger the sensor switch when the sensing plate rotates to the position of the sensor switch.

[0014] The positive effects of this utility model are as follows: The structure of the automatic dispensing equipment at the tail end of the laryngeal mask in this utility model is optimized. Through the intermittent rotation of the turntable, the laryngeal mask is reliably mounted on the positioning fixture at the loading station and transported to the dispensing station. The shifting device of the automatic dispensing mechanism controls the movement of the rotary drive mechanism. The dispensing head of the dispensing device is aligned with the dispensing point at the rear end. Then, the rotary drive mechanism drives the rotating frame to rotate 360 ​​degrees, causing the dispensing device to circle the dispensing point of the laryngeal mask once, thereby accurately completing the dispensing operation at the tail end of the laryngeal mask, ensuring uniform glue amount and accurate position, thus achieving efficient automated dispensing operation. This solution, through the coordinated design of the high-precision shifting device and the 360-degree rotating frame, ensures precise control of the dispensing position and flexible adaptation of the path, realizing fully automated operation of dispensing at the tail end of the laryngeal mask, significantly improving production efficiency and product consistency.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] The structure of the automatic dispensing device for the laryngeal mask tail end in this embodiment of the utility model is as follows: Figure 2-5As shown, the device includes a frame 1, an automatic dispensing mechanism 2 mounted on the frame 1, a turntable 3 mounted on the frame 1, and a positioning fixture 5 mounted on the turntable 3 for clamping and positioning the laryngeal mask 4. A cover 10 is fixed to the upper end of the frame 1, which protects the internal components. The turntable 3 is driven by a motor to rotate intermittently. The automatic dispensing mechanism 2 includes a shifting device 21, a rotating frame 22, a rotating drive mechanism 23, and a dispensing device 24. The shifting device 21 drives the rotating drive mechanism 23 to perform a moving action, and the rotating drive mechanism 23 drives the rotating frame 22 to rotate 360 ​​degrees. The dispensing device 24 is mounted on the rotating frame 22. The automatic dispensing device for the laryngeal mask tail end of this embodiment uses the intermittent rotation of the turntable 3 to dispensing material... The workstation reliably mounts the throat mask 4 onto the positioning fixture 5 and transports it to the dispensing station. The shifting device 21 of the automatic dispensing mechanism 2 controls the rotation drive mechanism 23 to move, and the dispensing head of the dispensing device 24 is aligned with the dispensing point at the rear. Then, the rotation drive mechanism 23 drives the rotating frame 22 to rotate 360 ​​degrees, causing the dispensing device 24 to circle around the dispensing point of the throat mask 4, thereby accurately completing the dispensing operation at the tail end of the throat mask 4, ensuring uniform glue volume and accurate positioning, thus achieving efficient automated dispensing operation. This solution, through the coordinated design of the high-precision shifting device 21 and the 360-degree rotating frame 22, ensures precise control of the dispensing position 43 and flexible adaptation of the path, realizing fully automated operation of dispensing at the tail end of the throat mask 4, significantly improving production efficiency and product consistency.

[0025] like Figure 2 As shown, the displacement device 21 can be a two-dimensional or three-dimensional drive device, preferably an electric linear slide as the actuator. The two-dimensional drive device consists of two mutually perpendicular electric linear slides, which control the movement of the X-axis and Y-axis respectively to achieve precise positioning in the plane. The three-dimensional control device adds an electric linear slide of the Z-axis to the two-dimensional drive device to achieve precise positioning in space. Through its precise motion control, the rotary drive mechanism 23 is driven to achieve precise control of the position and movement path of the dispensing device 24 in two-dimensional or three-dimensional space. Its structure is a conventional structure and will not be described in detail here.

[0026] The rotary drive mechanism 23 includes a motor, and the rotating frame 22 is fixed on the output shaft of the motor; the rotating frame 22 is driven to rotate by the rotation of the motor, and the structure is simple.

[0027] See Figure 5 As shown, the rotating frame 22 has a C-shaped structure. The upper end of the rotating frame 22 is fixedly connected to the rotating drive mechanism 23, and the lower end of the rotating frame 22 is fixedly connected to the dispensing device 24. The bending design of the C-shaped structure can play a role in avoiding interference between the rotating frame 22 and the throat mask 4 when it rotates.

[0028] See Figure 4The positioning clamp 5 includes a fixed base 51, a fixed clamping block 52, a movable clamping block 53, and a reaction spring 54. The fixed base 51 is fixed on the turntable 3, the fixed clamping block 52 is fixed on the fixed base 51, and the movable clamping block 53 is movably mounted on the fixed base 51 and is positioned opposite to the fixed base 51. The reaction spring provides elastic force to the movable clamping block 53, causing the movable clamping block 53 to maintain a tendency to move towards the fixed clamping block 52. The fixed clamping block 52 and the movable clamping block 53 cooperate to reliably clamp and position the laryngeal mask 4. When the laryngeal mask 4 is removed, the movable clamping block 53 is pushed to move away from the fixed clamping block 52, thereby removing the laryngeal mask 4 from the positioning clamp 5. The laryngeal mask 4 is easy to install and remove.

[0029] like Figure 3 and 4 A drive block 11 is fixed on the frame 1 for loading and unloading. The drive block 11 is provided with a guide slope 12. A linkage 532 is fixed at the lower end of the movable clamping block 53. When the linkage 532 rotates with the movable clamping block 53 to the position of the drive block 11, the linkage 532 contacts the guide slope 12 on the drive block 11. During the relative movement, the guide slope 12 applies a pushing force to the linkage 532. This pushing force is transmitted to the movable clamping block 53 through the linkage 532, driving it to move away from the fixed clamping block 52, thereby releasing the clamping of the throat mask 4 and allowing the throat mask 4 to be removed.

[0030] See Figure 4 The linkage 532 has a roller 533 adapted to abut against the guide slope 12, thereby reducing the frictional force of the roller 533 when it passes through the guide slope 12.

[0031] Continue reading Figure 4 The fixed base 51 is fixed with support blocks 55 at intervals, and the support blocks 55 are fixed with limit guide posts 56. The movable clamping block 53 is provided with guide post sleeve holes, which are sleeved with the limit guide posts 56. The reaction spring 54 is sleeved on the limit guide posts 56. By setting the support blocks 55 and the limit guide posts 56, the movable clamping block 53 can maintain a stable trajectory during movement, avoiding deviation or shaking caused by external forces or vibrations, thereby ensuring the accuracy and reliability of the clamping operation. At the same time, the reaction spring 54 is sleeved on the limit guide posts 56, which can also ensure the stability of the installation of the reaction spring 54, thereby better exerting its elastic effect.

[0032] The fixed clamping block 52 is provided with a contoured protrusion 521 that matches the shape of the head end cavity 44 of the laryngeal mask 4, and the movable clamping block 53 is provided with a clamping opening 531 facing the fixed clamping block 52. When the laryngeal mask 4 is installed on the positioning clamp 5, the contoured protrusion 521 is embedded in the head end cavity 44 of the laryngeal mask 4 to ensure that the laryngeal mask 4 can be accurately positioned during the clamping process and to prevent the laryngeal mask 4 from shifting or loosening. The clamping opening 531 on the movable clamping block 53 works in conjunction with the contoured protrusion 521 on the fixed clamping block 52 to further enhance the stability and reliability of the clamping.

[0033] Combination Figure 3 and Figure 4 The fixed base 51 is equipped with a detection device, which includes a detection fixing member 511 fixed on the fixed base 51, a detection rod 512 movable on the detection fixing member 511, and an elastic member (preferably a helical compression spring, not shown in the figure) sleeved on the detection rod 512. The elastic member provides an upward elastic force to the detection rod 512. The lower end of the detection rod 512 is provided with a sensing plate 513. The frame 1 is provided with a sensor switch 514, which is connected to the equipment control system. When the throat mask 4 is mounted on the positioning fixture 5, it applies downward pressure to the detection rod 512 and is adapted to trigger the sensor plate 513 when it rotates to the position of the sensor switch 514. After the throat mask 4 is removed from the positioning fixture 5, the detection rod 512 moves upward and resets under the elastic force of the elastic member, thereby moving the sensing plate 513 upward and losing the triggering of the sensor switch 514. In this way, the sensor switch 514 detects whether the positioning fixture 5 is equipped with a throat mask 4.

[0034] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this utility model.
