A glue application device

Abstract

This invention provides an adhesive application device, belonging to the field of automated assembly technology for medical accessories. It solves the problem of excessive and uneven glue application during the assembly of catheters and connectors. The adhesive application device includes an adhesive application claw and a glue storage box. The adhesive application claw is used to move horizontally back and forth to grip the catheter end on the carrier or to return to its original position to await glue exchange with the glue storage box. This application features a dipping head on the glue storage box, which can move up and down. When moving downwards, it can reach into the glue storage box to pick up glue; when moving upwards, it can approach the height of the adhesive application claw to be gripped or move to the height of the adhesive application claw to be gripped. When the adhesive application claw moves to the dipping head, it grips the dipping head and applies glue. This indirect glue application significantly reduces the amount of glue adhering to the surface of the claw, ensuring that the catheter surface is coated with an appropriate and controllable amount of glue. This results in an appropriate and even amount of glue at the joint when the catheter is finally assembled with the connector.

Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology of medical accessories, and relates to a glue coating device for assembling infusion sets, and more particularly to a device for coating the outer wall of a catheter with glue. Background Technology

[0002] Currently, the production of infusion sets in medical consumables has largely achieved fully automated processing. A crucial step in the automated production of infusion sets is connecting various accessories to the catheter tip. A common method for connecting catheters and accessories is adhesive bonding. This involves applying adhesive to the inner or outer wall of the catheter, then connecting the accessories to the catheter. Once the adhesive solidifies, the accessories are fixed to the catheter, forming a seal at the bonding point. Existing automated adhesive application devices include: A catheter external adhesive application device disclosed in application number 201610575290.1, which mainly includes grippers for encircling the catheter. The grippers move downwards into an adhesive container to pick up adhesive, then move again to grip the catheter tip, adhering the adhesive on the grippers to the catheter. The catheter then proceeds to the next station for connection of connectors and other components.

[0003] Such glue-applying devices can solve the basic problem of automatic glue application. However, due to the adhesive's stickiness, the applicator often carries a significant amount of glue onto the clamp after entering the glue container. Upon contact with the catheter, a large amount of glue adheres to the catheter. This glue, under its own weight, deposits or even drips down the catheter, leading to uneven glue distribution when subsequent connectors and accessories are fitted into the catheter, sometimes even resulting in glue clumps accumulating on the lower side. While this can be reduced by shaking the applicator or increasing its waiting time, the effect is not ideal. Excessive initial glue application leads to less glue on the upper surface of the applicator during the waiting or shaking process, while the lower surface accumulates, resulting in uneven distribution. This leads to less glue on the upper surface, making it prone to air leakage, while more glue accumulates on the lower surface. In short, the yield rate of infusion sets assembled in this way is not high. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an adhesive application device. It solves the technical problem of excessive and uneven adhesive application during the assembly of conduits and connectors.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A glue-applying device includes an openable and closable glue-applying claw, characterized in that the glue-applying claw can reciprocate in the horizontal direction, a glue storage box is provided below the movement path of the glue-applying claw, the glue storage box has an opening above it and a glue-dipping head that can move up and down is provided at the opening position, and when the glue-dipping head and the glue-applying claw are at the same height, the glue-dipping head and the glue-applying claw are facing each other.

[0007] This adhesive application device consists of two parts: an adhesive application claw and an adhesive storage box. The adhesive application claw is used to move horizontally back and forth to grip the end of the conduit on the carrier or to return to its original position to wait for adhesive exchange with the adhesive storage box. This application has designed an adhesive dipping head on the adhesive storage box, which can move up and down. When moving downward, it can extend into the adhesive storage box to dip in adhesive. When moving upward, it can approach the height of the adhesive application claw to wait to be gripped by the adhesive application claw or move to the height of the adhesive application claw to wait to be gripped. When the adhesive application claw moves to the adhesive dipping head, it applies adhesive by gripping the adhesive dipping head. This indirect application of adhesive greatly reduces the amount of adhesive adhering to the surface of the adhesive application claw, allowing the surface of the conduit to adhere to an appropriate amount of adhesive with controllable quantity. This ensures that the adhesive at the joint is appropriate and uniform when the conduit and the connector are finally assembled.

[0008] Furthermore, the glue-dipping head and the glue-applying claw move independently. The glue-dipping head can pre-dip the glue in the glue-applying claw and wait, making the movements of each mechanism more coordinated and speeding up the cycle. At the same time, the waiting time after the glue-dipping head leaves the glue storage box allows some glue to drip off under gravity, making the amount of glue adhering to the glue-dipping head controllable when the glue-applying claw grasps the glue-dipping head. Ultimately, this effectively reduces the amount of glue adhering to the guide tube and makes it more uniform.

[0009] In the above-mentioned adhesive application device, the adhesive head can be moved upward to the height of the moving path of the adhesive application claw, and the position of the adhesive head is opposite to that of the adhesive application claw.

[0010] This is one of the solutions for docking the glue-dipping head with the glue-applying claw. In this solution, the glue-dipping head can dip into the glue in the glue storage box by moving downwards, and can move upwards directly to the height of the horizontal movement path of the glue-applying claw and face it opposite to the glue-applying claw. When the glue-applying claw moves horizontally back and forth, it can directly dock with the glue-dipping head and grasp and apply glue. This design ensures that the glue applied to the guide tube is appropriate and uniform while ensuring the coordinated movement of the mechanism.

[0011] In the above-mentioned glue application device, the glue application claw can move downward to the height of the glue-dipping head and can move closer to the glue-dipping head.

[0012] This is another solution for connecting the adhesive applicator and the adhesive applicator claw. In this solution, the adhesive applicator moves downward to pick up the adhesive and moves upward to detach from the adhesive storage box and position itself above it. The adhesive applicator claw can move downward to align with the position of the adhesive applicator and thus grasp and adhere the adhesive. This design ensures that the upward movement of the adhesive applicator does not interfere with the reciprocating movement of the adhesive applicator claw. The adhesive applicator can pre-pick up the adhesive and wait, during which time the adhesive can overflow and drip on its own. When the adhesive applicator claw grasps the adhesive applicator claw, the amount of adhesive adhering to the adhesive applicator claw is further reduced and made more uniform, thus ensuring that the final amount of adhesive adhering to the conduit is appropriate and uniform.

[0013] In the above-mentioned glue application device, the upper frame of the glue storage box is fitted with a bracket. The bracket has a square ring structure and includes an upper crossbeam and a lower crossbeam. The upper crossbeam is located above the opening of the glue storage box and the glue-applying head is fixed below the upper crossbeam. The lower crossbeam is located below the glue storage box and a cylinder is connected to it.

[0014] The bracket of this application has a square ring structure that is framed around the glue storage box. The cylinder pushes the lower crossbeam to lift the whole structure, especially to move the glue dipping head on the upper crossbeam up and down. This bracket design has high stability during movement, which makes the movement of the glue dipping head highly accurate and facilitates precise gripping by the glue application claw. The precise alignment of the glue dipping head and the glue application claw makes the glue adhering to the surface of the glue application claw more uniform, and ultimately makes the glue adhering to the tube more uniform.

[0015] Furthermore, the design of the upper and lower crossbeams surrounding the outside of the glue storage box makes it easier to adjust the position of the bracket relative to the glue storage box. This facilitates adjusting the flatness and levelness of the glue-applying head connected to the bracket, making it easier to set the accuracy of the relative position of the glue-applying head and the glue-applying claw. Once adjusted, the bracket is very stable.

[0016] Furthermore, the glue applicator is fixed below the upper crossbeam, which improves stability when the crossbeam is on top and the glue applicator is on the bottom. At the same time, the crossbeam will not come into contact with the glue when the glue applicator is dipping in glue, reducing glue consumption and preventing glue from dripping onto the glue applicator.

[0017] In the above-mentioned adhesive applicator, the bottom of the upper crossbeam has a connecting part protruding downwards, and the adhesive applicator head is fixed on the side of the connecting part.

[0018] The upper crossbeam moves vertically. This application designs a downward protruding connecting part at the bottom of the upper crossbeam to support and fix the glue applicator. After the glue applicator is installed, its stability during movement is better. The glue applicator is hung and fixed below the upper crossbeam. When applying glue, the rest of the bracket except for the connecting part does not contact the glue storage box, effectively controlling the amount of glue applied so that the glue applied to the tube is appropriate and even.

[0019] In the above-mentioned adhesive application device, the adhesive dipping head has a cylindrical structure and is made of stainless steel, and the axis of the adhesive dipping head is parallel to the moving direction of the adhesive application claw.

[0020] The adhesive applicator of this application is supported by stainless steel. Stainless steel adhesive applicators do not easily absorb adhesive. After applying adhesive, only a small amount of adhesive will adhere to the surface and be evenly distributed. Similarly, after the adhesive applicator holds the adhesive applicator, only a small amount of adhesive will adhere to its surface for coating the conduit. This design controls the amount of adhesive applied, which can greatly reduce excessive adhesive residue on the conduit and ensure that only a small amount of adhesive adheres to the conduit and is evenly distributed.

[0021] In the above-mentioned adhesive application device, the adhesive application claw includes a claw body one and a claw body two that can be opened and closed in the horizontal direction. When the claw body one and the claw body two are combined, the ends of the claw body one and the claw body two surround to form a circular hole and the inner wall surface of the circular hole is smooth. The diameter of the adhesive dipping head is close to the inner diameter of the circular hole and a number of annular grooves are provided on the outer peripheral surface of the adhesive dipping head.

[0022] The surface of the adhesive applicator of this application has an annular groove. After the adhesive is applied, a large amount of adhesive will adhere to the annular groove. The size of the adhesive applicator itself is close to the size of the circular hole. When the adhesive claw grips the adhesive applicator and pulls it out, it can ensure that the inner wall of the circular hole is evenly coated with adhesive without being excessive, thereby reducing the amount of adhesive on the coated guide tube to an appropriate amount and evenly distributed.

[0023] Furthermore, the adhesive applicator opens and closes horizontally. When the adhesive applicator is open, the round hole splits into two half-holes to form a vertical gap, allowing excess adhesive to flow out. This further reduces the amount of adhesive applied to the conduit by the adhesive applicator and, to some extent, makes the adhesive distribution more uniform.

[0024] In the above-mentioned adhesive application device, the claw body one and the claw body two are respectively provided with half groove one and half groove two near their ends. When the claw body one and the claw body two are combined, the half groove one and the half groove two surround and form a channel for a vertical through circular hole.

[0025] By opening a channel near the end of the adhesive applicator, the adhesive inside the round hole or the inside of the adhesive applicator can flow out through the channel. Even excess adhesive that overflows during the movement of the adhesive applicator can be discharged through the channel, reducing the amount of adhesive adhering to the end of the adhesive applicator. This allows for proper control of the amount of adhesive applied to the conduit each time, ensuring that the adhesive applied to the conduit remains uniform.

[0026] In the above-mentioned adhesive application device, the claw body one and the claw body two are respectively provided with a semi-annular groove one and a semi-annular groove two along their surfaces, and the semi-annular groove one and the semi-annular groove two are respectively connected to the semi-groove one and the semi-groove two.

[0027] The design of semi-annular groove one and semi-annular groove two is equivalent to opening guide grooves on the surface of claw one and claw two, which can effectively guide the glue flowing out of the channel and the glue flowing out of the surface of the glue-coating claw downwards to overflow and discharge, reducing the amount of glue adhering on the glue-coating claw.

[0028] In the above-mentioned adhesive application device, the adhesive application device further includes a frame, on which a mounting base that can reciprocate in the horizontal direction is provided, and a rotating arm that can rotate circumferentially is connected to the mounting base. The rotation axis of the rotating arm is horizontally arranged and faces the moving direction of the mounting base, and the adhesive application claw is fixed on the rotating arm and faces the same direction as the rotating arm.

[0029] The adhesive applicator of this application is connected to a rotating arm. Driven by the rotating arm, it rotates circumferentially. The design allows the adhesive applicator to rotate while holding the adhesive applicator head, ensuring even adhesion of adhesive to the applicator and thus applying a more uniform layer of adhesive to the conduit. It also helps to remove excess adhesive. Furthermore, the rotation of the applicator during contact with the conduit ensures that the adhesive carried by the applicator is applied evenly to the outer wall of the conduit.

[0030] In the above-mentioned adhesive application device, a push cylinder is installed on the mounting base. The push rod of the push cylinder is connected to the rotating arm and can drive the rotating arm to extend and retract in the direction of its rotation axis.

[0031] When the adhesive applicator contacts the adhesive head and the guide tube, it is pushed forward and backward by a separately designed push cylinder. This allows for more precise control of the feed amount, ensuring a stable position of the adhesive applied to the end of the guide tube and a more uniform application of the adhesive.

[0032] Compared with existing technologies, the advantages of this product are:

[0033] 1. The glue-applying claw does not extend into the glue storage box to contact the glue. Instead, it applies the glue by gripping and dipping the glue head. This indirect application of glue greatly reduces the amount of glue adhering to the surface of the claw, allowing the surface of the conduit to be covered with an appropriate and controllable amount of glue. This ensures that the glue at the joint is applied in an appropriate and even manner when the conduit and connector are assembled.

[0034] 2. The glue-applying claw is connected to the rotating arm. Driven by the rotating arm, it rotates circumferentially to throw off excess glue, so that the glue carried on the glue-applying claw is applied evenly to the outer wall of the conduit.

[0035] 3. The glue-dipping head and the glue-applying claw move independently. The glue-dipping head can pre-dip the glue in the glue-applying claw and wait, which makes the movements of each mechanism more coordinated and speeds up the cycle. Attached Figure Description

[0042] 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.

[0043] Example 1

[0044] like Figure 1 and Figure 4The illustrated adhesive applicator is used for external adhesive application to the end of a conduit. This applicator includes a frame 5 and an adhesive storage box 2. An electric cylinder assembly for power supply is mounted on the top of the frame 5. A mounting base 6 is connected to the slider of the electric cylinder assembly. The top of the mounting base 6 is fixed to the slider, and its lower end hangs in the middle of the frame 5. The electric cylinder assembly drives the mounting base 6 to move linearly in a horizontal direction, cycling between the initial position, the adhesive application position, and the adhesive application position. This provides single-point control and high precision. A rotating arm 7 is mounted on the mounting base 6, and an adhesive application claw 1 is mounted on the rotating arm 7. The rotating arm 7 drives the adhesive application claw 1 to rotate, ensuring more even adhesive application. The mounting base 6 drives the adhesive application claw 1 to move linearly, allowing for efficient switching between workstations. The adhesive storage box 2 is mounted on the workbench of the fixed frame 5 or another independent workbench. The overall height of the adhesive storage box 2 is lower than that of the adhesive application claw 1, preferably to avoid interfering with the movement of the adhesive application claw 1. A dipping head 3 that can move up and down is installed on the glue storage box 2. The dipping head 3 moves downward to pick up glue, and moves upward to carry the glue to the glue application position to wait for the glue application claw 1 to come over and grasp the glue. This indirect glue dipping greatly reduces the amount of glue adhering to the surface of the glue application claw 1, so that the surface of the conduit is covered with an appropriate amount of glue that can be controlled in quantity, so that when the conduit and the connector are finally assembled, the glue at the joint is appropriate and uniform.

[0045] like Figure 4 The rotating arm 7 shown comprises a rotating shaft, a drive motor, a bearing housing, and an L-shaped support platform. The applicator claw 1 is fixed to the support platform. The support platform is fixed to the end of the rotating shaft, and the rotating shaft as a whole is connected to the platform of the mounting base 6 via the bearing housing. The drive motor is connected to the rotating shaft via a synchronous belt and a synchronous pulley, driving the rotating shaft to rotate. The rotating shaft has a certain sliding space in the axial direction. A push cylinder 8 is fixed in the tail area of ​​the mounting base 6. The push rod of the push cylinder 8 is connected to the tail end of the rotating shaft on the rotating arm 7. The push cylinder 8 drives the rotating shaft to move within the sliding space, thereby controlling the extension and retraction of the applicator claw 1. When the applicator claw 1 contacts the adhesive head 3 and the guide tube, it is pushed forward and backward by a separately provided push cylinder 8. This allows for better and more precise control of the feed amount, ensuring a stable position of the adhesive applied to the end of the guide tube and more uniform adhesive application.

[0046] like Figure 4 and Figure 5The specific structure of the adhesive applicator 1 shown is as follows: The adhesive applicator 1 includes a two-finger cylinder 43, which is fixed horizontally on the mounting position of the aforementioned support platform. The opening and closing direction of the two-finger cylinder 43 is perpendicular to the axis of the connecting shaft. Claw body 11 and claw body 2 12 are fixed to the two fingers of the two-finger cylinder 43, respectively. The ends of claw body 11 and claw body 2 12 surround to form a circular hole 13. The center line of the circular hole 13 coincides with the axis of the connecting shaft. The inner wall surface of the circular hole 13 is smooth. This design ensures stable opening and closing and prevents eccentricity. When the circular hole 13 grips and rotates with the material guide tube or the adhesive applicator head 3, it maintains good accuracy and concentricity, resulting in uniform adhesive coverage on the surface of the guide tube. The position where the ends of claw body 11 and claw body 2 12 are located is the main contact position with the guide tube and is called the adhesive application part. The size of the adhesive application part varies, and the inner diameter of the circular hole 13 at the adhesive application part can be designed according to the diameter of the guide tube to be coated. Half-grooves 141 and 142 are made on claw body 11 and claw body 22 near the glue application part. As claw body 11 and claw body 22 close, half-grooves 141 and 142 surround and form a complete channel 14, which laterally penetrates the round hole 13. This allows the glue inside the round hole 13 or inside the glue application claw 1 to flow out from the channel 14. Especially when the glue application claw 1 rotates, the centrifugal force will throw the excess glue out from the channel 14, thereby ensuring that the amount of glue applied to the guide tube each time is properly controlled, and ensuring that the glue applied to the guide tube remains uniform. Furthermore, an annular groove 31 is provided on the outer periphery of the channel 14 of the adhesive claw 1. After the claw body 11 and the claw body 2 12 are separated, the annular groove 31 is separated along its surface to form a semi-annular groove 15 and a semi-annular groove 2 16. The semi-annular groove 15 and the semi-annular groove 2 16 respectively connect with the semi-groove 141 and the semi-groove 2 142 to form concave ribs for better flow guidance.

[0047] like Figure 2 and Figure 3The glue storage box 2 shown has a square box structure. The interior of the glue storage box 2 has a chamber for holding glue. The top of the glue storage box 2 has an opening 21. An upper crossbeam 41 is horizontally arranged above the opening 21. The two ends of the upper crossbeam 41 extend toward the opposite sides of the glue storage box 2, and vertical connecting sheet metal parts are fixed to the two ends of the upper crossbeam 41. A lower crossbeam 42 is horizontally arranged at the bottom of the glue storage box 2. The lower crossbeam 42 is connected and fixed to the above-mentioned connecting sheet metal parts to form a complete bracket 4. A cylinder 43 is fixed on the side of the base frame that supports the glue storage box 2. The cylinder 43 is directly connected to the lower crossbeam 42 and pushes the lower crossbeam 42 and the upper crossbeam 41 to lift synchronously. The bracket 4 designed in this way has high stability when moving. The adhesive applicator 3 of this application is directly fixed to the protruding connecting part 411 at the bottom of the upper crossbeam 41. Based on the stable movement of the bracket 4, the adhesive applicator 3 moves with high precision, facilitating precise gripping by the adhesive applicator 1. The precise alignment of the adhesive applicator 3 and the adhesive applicator 1 ensures that the adhesive adhering to the surface of the adhesive applicator 1 is relatively uniform, ultimately resulting in more uniform adhesive adhering to the conduit. Furthermore, the design of the upper crossbeam 41 and lower crossbeam 42, which surround the outer side of the adhesive storage box 2, makes it easier to adjust the overall position of the bracket 4 relative to the adhesive storage box 2. This facilitates adjusting the flatness and levelness of the adhesive applicator 3 connected to the bracket 4, making it easier to set the precision of the relative position between the adhesive applicator 3 and the adhesive applicator 1, and ensuring high stability after adjustment. The adhesive applicator 3 hangs below the upper crossbeam 41. When applying adhesive, except for the connecting part 411, the rest of the bracket 4 does not contact the adhesive storage box 2, effectively controlling the amount of adhesive applied, resulting in an appropriate and uniform amount of adhesive applied to the conduit.

[0048] like Figure 1 and Figure 3The adhesive applicator 3 shown is cylindrical in shape and has spaced annular grooves 31 on its surface. The size of the adhesive applicator 3 is adapted to the inner diameter of the adhesive applicator 1, and its basic size is slightly smaller than the inner diameter of the circular hole 13 of the adhesive applicator 1. After applying adhesive, a considerable amount of adhesive will adhere to the annular grooves 31. When the adhesive applicator 1 grips the adhesive applicator 3 and pulls it out, it ensures that the inner wall of the circular hole 13 is evenly coated with adhesive without being excessive, thereby reducing the amount of adhesive on the coated guide tube to an appropriate level and ensuring even distribution. The material of the adhesive applicator 3 is preferably 316 stainless steel, and the axis of the adhesive applicator 3 is parallel to the center line of the circular hole 13 on the adhesive applicator 1. The stainless steel adhesive applicator 3 does not easily absorb adhesive. After applying adhesive, only a small amount of adhesive adheres to the surface and is evenly distributed. Similarly, the adhesive applicator 1, after holding the adhesive applicator 3, also has only a small amount of adhesive adhering to its surface for coating the conduit. This design effectively controls the amount of adhesive applied, minimizing excessive adhesive residue and ensuring a small, evenly distributed amount of adhesive on the conduit. Furthermore, the design allows for the control of the adhesive applicator 1's rotation when it contacts the adhesive applicator 3, ensuring even adhesive application on the applicator 1 and resulting in a more uniform coating of adhesive on the conduit. It also allows excess adhesive to be shaken off.

[0049] like Figures 1-5 The actual glue application process of the glue application device shown is as follows: First, the glue application claw 1 and the glue dipping head 3 are simultaneously positioned, or the glue dipping head 3 is positioned first to reach the glue application position. Second, the glue application claw 1 opens, and the cylinder 8 pushes the glue application claw 1 forward. The glue application claw 1 closes and grips the glue dipping head 3. Then, the cylinder 8 pushes the glue application claw 1 backward. Third, the glue dipping head 3 moves downward to reset and picks up glue and waits. Fourth, the electric cylinder drives the glue application claw 1 forward to the carrier and grips the end of the infusion set for rotational glue application, which is more even and removes excess glue. Fifth, the electric cylinder drives the glue application claw 1 backward to reset, and the glue application is completed. Subsequent processing repeats the above operations.

[0050] Example 2

[0051] In this embodiment, the other structures are basically the same as in Embodiment 1, except that the adhesive applicator 1 can move downwards to the height of the adhesive dipping head 3 and move towards the adhesive dipping head 3. The mounting base 6 is designed as a mechanism that can move up and down. Through the structure of driving components such as driving cylinders and guide rods, the mounting base 6 can move up and down, allowing the adhesive applicator 1 fixed on the mounting base 6 to move vertically to correspond with the position of the adhesive dipping head 3. The adhesive applicator 1 can grasp and apply adhesive by moving downwards to correspond with the position of the adhesive dipping head 3. This design ensures that the upward movement of the adhesive dipping head 3 will not interfere with the reciprocating movement of the adhesive applicator 1. The adhesive dipping head 3 can be pre-dipping in adhesive and waiting. During the waiting process, the adhesive can overflow and drip down on its own. When the adhesive applicator 1 grasps the adhesive dipping head 3, the amount of adhesive adhering to the adhesive applicator 1 is further reduced and made more uniform, so that the final amount of adhesive adhering to the conduit is appropriate and uniform.

[0052] Example 3

[0053] In this embodiment, the other structures are basically the same as in embodiment two. The difference is that the mounting base 6 cannot be positioned in the vertical direction in this embodiment. However, a misalignment cylinder is designed between the glue-applying claw 1 and the support platform. The misalignment cylinder can push the glue-applying claw 1 down so that it corresponds to the position of the glue-dipping head 3 and dips in glue, which can achieve a technical effect similar to that of embodiment two.

[0054] Example 4

[0055] In this embodiment, the other structures are basically the same as in embodiment one. The difference is that when the glue-applying claw 1 of this application grips the glue-applying head 3, the drive motor will drive the glue-applying claw 1 to rotate to shake off excess glue and make the glue adhering on the glue-applying claw 1 more uniform. This design makes the glue on the tube coated at the end more uniform.

[0056] Example 5

[0057] In this embodiment, the other structures are basically the same as in embodiment one. The difference is that the glue-dipping head 3 in this embodiment is fixed on the rotating shaft, which is driven to rotate by a drive component, which can be a cylinder or a motor. The glue-dipping head 3 switches its position in the vertical direction by swinging up and down. It rotates downward to enter the glue storage box 2 to dip in glue, and rotates upward to align with the glue-applying claw 1. This design can achieve the same technical effect as in embodiment one.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
