Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing equipment, and in particular to a glue applicator for assembling protective bottles. Background Technology

[0002] An infusion pump is an intelligent infusion device that includes a protective bottle. The protective bottle consists of a bottle body and an end cap. Currently, during assembly, adhesive is applied to the end of the bottle body, and then the end cap is fastened onto the bottle body to achieve bonding.

[0003] Currently, assembly is done manually, typically by applying two dots of glue at intervals to the end of the bottle, which generally ensures the connection strength between the bottle and the end cap. However, during actual transportation, severe vibrations can still cause the bottle to detach from the end cap. Applying three dots or even a ring of glue to the end of the bottle would significantly reduce assembly efficiency and increase production costs.

[0004] In addition, when applying glue manually, some glue will inevitably be applied to the outside of the part where the bottle end meets the cap, resulting in glue residue on the bottle and affecting product quality. Utility Model Content

[0005] To address the aforementioned technical deficiencies, this invention provides a glue-applying device for assembling bottle protectors, which can apply glue to the ends of the bottle body in one go, achieving high efficiency and stability.

[0006] This utility model discloses a glue application device for bottle protection assembly, including a base. The base has a hollow structure inside and an open structure at the top. The hollow structure inside the base is used to hold glue. A mounting seat is provided inside the base, and at least one swing arm is provided on the mounting seat. The swing arm and the mounting seat are rotatably connected by a pin. A vertical guide post is provided at the center of the base, and a positioning platform is sleeved on the guide post. The positioning platform is slidably connected along the guide post. One end of the swing arm extends below the positioning platform, and the other end of the swing arm extends to the outside of the base. Adhesive-absorbing cotton is provided on the swing arm outside the base, and the adhesive-absorbing cotton is located on the side of the swing arm closer to the center of the base. The adhesive-absorbing cotton on the swing arm extends into the inside of the base. A first spring is provided on the lower surface of the swing arm below the positioning platform, and the lower end of the first spring is fixed inside the base.

[0007] The swing arms are arranged at intervals in a circular direction with the positioning platform as the center.

[0008] The positioning platform has a truncated cone structure that is smaller at the top and larger at the bottom. On the lower circumferential side wall of the positioning platform, there is a raised positioning step. The diameter of the positioning platform above the positioning step is smaller than the inner diameter of the bottle opening, and the outer diameter of the positioning step is larger than the inner diameter of the bottle opening.

[0009] Positioning steps are spaced apart circumferentially, and a cover plate is provided at the opening of the base. The cover plate has a hollow structure corresponding to the swing arm and the positioning steps. A limiting step is provided on the positioning platform below the positioning steps. The outer diameter of the limiting step is larger than the outer diameter of the positioning steps. When the positioning platform rises, the limiting step contacts the lower surface of the cover plate.

[0010] The second spring is fitted onto the guide post below the positioning platform.

[0011] It also includes an end cap, which is hollow inside and open at the bottom. The opening of the end cap fits onto the outside of the base. At least two positioning blocks are spaced apart on the inner side wall of the end cap. When the end cap covers the base, the positioning blocks abut against the top of the base.

[0012] Several positioning grooves are provided on the outer side wall of the base. The positions of the positioning grooves correspond one-to-one with the positioning blocks. The positioning grooves are formed by the bottom surface of the base being recessed upwards. When the lower end of the base is inserted into the end cap, the positioning blocks are inserted into the positioning grooves.

[0013] Multiple mounting seats are provided inside the base. Each swing arm is connected to a mounting seat by a pin. The mounting seat has an elongated hole, the length of which is perpendicular to the axis of the pin. Bolts are inserted through the elongated hole to fix the mounting seat and the base.

[0014] The end of the swing arm is bent inward to form a positioning part, which abuts against the end of the absorbent cotton to limit the position of the end of the absorbent cotton on the swing arm when the absorbent cotton is squeezed.

[0015] The glue-applying device for bottle assembly obtained by this utility model can apply glue to the end of the bottle body and complete the glue application in one go. It is fast, efficient, accurate and stable, and greatly improves the glue application and assembly efficiency. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Example 1:

[0027] like Figures 1-6 As shown, this utility model discloses a glue-applying device for bottle protection assembly, including a base 1. The base 1 has a hollow internal structure and an open upper end. A mounting seat 4 is provided inside the base 1, and at least one swing arm 5 is provided on the mounting seat 4. The swing arm 5 is rotatably connected to the mounting seat 4 via a pin 6. A vertical guide post 3 is provided at the center of the base 1, and a positioning platform 2 is sleeved on the guide post 3. The positioning platform 2 is slidably connected along the guide post 3. One end of the swing arm 5 extends below the positioning platform 2, and the other end of the swing arm 5 extends to the outside of the base 1. An absorbent cotton 7 is provided on the swing arm 5 outside the base 1, and the absorbent cotton 7 is located on the side of the swing arm 5 closer to the center of the base 1. The absorbent cotton 7 on the swing arm 5 extends into the interior of the base 1. A first spring 8 is provided on the lower surface of the swing arm 5 below the positioning platform 2, and the lower end of the first spring 8 is fixed inside the base 1.

[0028] The base 1 serves as a carrier, and its specific shape is not limited. However, it is preferably a regular shape such as a circle or square, with both the upper and lower surfaces remaining flat. The base 1 has a hollow interior structure for assembling components such as the mounting base 4 and the swing arms 5, and also for holding the adhesive. The number of swing arms 5 on the mounting base 4 can be selected according to actual needs. Generally, three swing arms 5 are used, allowing simultaneous application of adhesive to three points on the bottle body 13 port during normal operation. Alternatively, in other embodiments, only one swing arm 5 can be used. Although only the absorbent cotton 7 on one swing arm 5 will contact the bottle body 13 port, the bottle body 13 can be rotated during the actual adhesive application process, allowing the absorbent cotton 7 to circumferentially coat the entire bottle body 13 port. This can be selected based on actual needs. Furthermore, if adhesive needs to be applied to four points on the bottle body 13 port, four swing arms 5 can be used; if five points need adhesive application, five swing arms 5 can be used.

[0029] A positioning platform 2 is provided on the guide column 3, which is used to position the bottle body 13. The end of the bottle body 13 is inverted and placed on the positioning platform 2. The positioning platform 2 can be a frustoconical structure. When the bottle body 13 is inverted and placed on the positioning platform 2, its lower end is engaged with the positioning platform 2, thereby limiting its position. When the bottle body 13 is pressed down, it can drive the positioning platform 2 to move up and down on the guide column 3. One end of the swing arm 5 extends to the bottom of the positioning platform 2, and a first spring 8 is provided on the lower surface of the swing arm 5 below the positioning platform 2. In its natural state, the first spring 8 pushes the swing arm 5 below the positioning head upward, causing the positioning platform 2 to rise. At this time, since the swing arm 5 rotates through the pin 6, the other end of the swing arm 5 descends, causing the lower end of the absorbent cotton 7 on the swing arm 5 to be immersed in the glue. At the same time, during the swing of the swing arm 5, the absorbent cotton 7 can also move away from the positioning platform 2. During the application of adhesive, the bottle 13 is placed upside down on the positioning platform 2, causing the positioning platform 2 to move up and down on the guide post 3. When the positioning platform 2 moves down to the appropriate position, the positioning platform 2 presses down the swing arm 5 below it, overcoming the elastic force of the first spring 8, causing the swing arm 5 to swing. The swing arm 5 then drives the adhesive absorbent cotton 7 at the other end to move up and move closer to the positioning platform 2, so that the adhesive absorbent cotton 7 contacts the end of the bottle 13, thus achieving the application of adhesive.

[0030] The swing arms 5 are arranged circumferentially around the positioning platform 2. The swing arms 5 are arranged circumferentially around the positioning platform 2, and can also be of the same shape with the pins 6 positioned on the same circumference. This ensures that during the downward movement of the positioning platform 2, the movements of all swing arms 5 are synchronized, meaning that the absorbent cotton 7 on each swing arm 5 simultaneously contacts the port of the bottle body 13, and the amount of adhesive applied to the port of the bottle body 13 by the absorbent cotton 7 remains essentially consistent.

[0031] The positioning platform 2 has a truncated cone structure, wider at the bottom than the top. A raised positioning step 10 extends outwards from the lower circumferential sidewall of the positioning platform 2. The diameter of the positioning platform 2 above the positioning step 10 is smaller than the inner diameter of the bottle opening, and the outer diameter of the positioning step 10 is larger than the inner diameter of the bottle opening. The truncated cone structure facilitates the insertion of the end of the bottle 13 into the positioning platform 2, while maintaining a stable position for the bottle 13 on the platform 2. The positioning step 10 at the lower end of the positioning platform 2 restricts the position of the bottle 13 on the platform 2, keeping the bottle 13 vertical. When the bottle 13 presses down on the positioning step 10, it causes the positioning platform 2 to move downwards, causing the absorbent cotton 7 on the swing arm 5 to swing upwards, applying adhesive to the end of the bottle 13. The entire process is more stable and reliable.

[0032] Positioning steps 10 are spaced apart circumferentially, and a cover plate 11 is provided at the opening of the base 1. The cover plate 11 has a hollow structure corresponding to the swing arm 5 and the positioning steps 10. A limiting step 12 is provided on the positioning platform 2 below the positioning steps 10. The outer diameter of the limiting step 12 is larger than the outer diameter of the positioning steps 10. When the positioning platform 2 rises, the limiting step 12 contacts the lower surface of the cover plate 11.

[0033] Positioning steps 10 are spaced circumferentially, meaning they are not a ring structure. A cover plate 11 is mounted on the base 1. Because the cover plate 11 has a perforated structure at the corresponding positions of the swing arm 5 and the positioning steps 10, the lifting and lowering of the swing arm 5 and the positioning steps 10 will not interfere with the cover plate 11. Similarly, the positioning platform 2 is located at the center of the movement, and since the cover plate 11 is ring-shaped, the lifting and lowering of the positioning platform 2 will not interfere with the cover plate 11. Furthermore, because the positioning steps 10 are spaced apart, the cover plate 11 extends between the positioning steps 10. When the end of the bottle 13 abuts against the positioning steps 10, causing the positioning platform 2 to move downwards, the end of the bottle 13 will eventually abut against the cover plate 11 between the positioning steps 10, achieving precise positioning of the bottle 13. This ensures that the bottle 13 remains in the designated position regardless of the operator, resulting in higher accuracy in adhesive application.

[0034] In addition, a limiting step 12 is provided below the positioning step 10. The limiting step 12 is annular. In its natural state, the first spring 8 can push the positioning platform 2 upward, so that the limiting step 12 cover plate 11 contacts, thereby preventing the positioning platform 2 from rising excessively and falling off the guide post 3.

[0035] The cover plate 11 also reduces the open area of ​​the base 1 opening, thereby reducing the evaporation of adhesive.

[0036] A second spring 9 is fitted onto the guide post 3 below the positioning platform 2. The second spring 9 is always compressed and exerts an upward thrust on the positioning platform 2 to maintain its stability. This reduces the elastic force required for the first spring 8, making the assembly and operation of the swing arm 5 more stable. During the downward pressing of the bottle body 13, the elastic force of the first spring 8 and the second spring 9 needs to be overcome to cause the positioning platform 2 to move downward, allowing the swing arm 5 to swing, so that the adhesive cotton 7 contacts the lower end of the bottle body 13 to achieve adhesive application.

[0037] like Figure 9 As shown, multiple mounting seats 4 are provided inside the base 1. Each swing arm 5 is connected to a mounting seat 4 by a pin 6. An elongated hole 17 is provided on the mounting seat 4. The length direction of the elongated hole 17 is perpendicular to the axial direction of the pin 6. A bolt 18 is inserted through the elongated hole 17 to fix the mounting seat 4 and the base 1.

[0038] The number of mounting bases 4 is determined by the number of swing arms 5, with a one-to-one correspondence. The mounting base 4 is fixed to the base via elongated holes 17 and bolts 18. In actual use, the relative position of the bolts 18 and elongated holes 17 can be adjusted according to actual needs, thereby adjusting the position of the swing arms 5 so that the absorbent cotton 7 on the swing arms 5 can precisely contact the lower end of the bottle body 13, ensuring accurate and reliable glue application. The glue application position can be adjusted according to actual product requirements.

[0039] The end of the swing arm 5 is bent inward to form a positioning part 19. The positioning part 19 abuts against the end of the absorbent cotton 7, which is used to limit the position of the end of the absorbent cotton 7 on the swing arm 5 when the absorbent cotton 7 is squeezed. Since the absorbent cotton 7 is generally fixed to the swing arm 5 by a connector, in the actual glue application process, the end of the absorbent cotton 7 is squeezed to apply the glue to the bottle body 13. However, this process can easily cause displacement of the absorbent cotton 7. Therefore, the positioning part 19 is formed by bending the end of the swing arm 5 inward. The positioning part 19 abuts against the end of the absorbent cotton 7, and the squeezing of the absorbent cotton 7 during repeated glue application will not cause the position of the absorbent cotton 7 to change, thus ensuring the accuracy of glue application. Of course, the bending width of the positioning part 19 must be less than the thickness of the absorbent cotton 7 to avoid interference between the positioning part 19 and the bottle body 13 during glue application, which would affect the glue application effect.

[0040] Example 2:

[0041] like Figures 7-8As shown, this utility model discloses a glue-applying device for bottle assembly. The difference between this device and Embodiment 1 is that it further includes an end cap 15. The end cap 15 is hollow inside, with an opening at its lower end. The opening of the end cap 15 fits onto the outside of the base 1. At least two positioning blocks 16 are spaced apart on the inner wall of the end cap 15. When the end cap 15 covers the base 1, the positioning blocks 16 abut against the top of the base 1. To seal the upper opening of the base 1 when not in use to prevent glue evaporation, an end cap 15 is also designed. The hollow end cap 15 is used to fasten onto the base 1, closing the upper opening of the base 1. Simultaneously, components such as the positioning platform 2 on the base 1 are located inside the end cap 15. To maintain positioning when the end cap 15 is engaged with the base 1, and to create a certain space between the base 1 and the end cap 15 to accommodate the positioning platform 2 and other components, positioning blocks 16 are provided on the inner wall of the end cap 15. The positioning blocks 16 abut against the upper end of the base 1, thus positioning the end cap 15.

[0042] Several positioning grooves 14 are provided on the outer side wall of the base 1. The positions of the positioning grooves 14 correspond one-to-one with the positioning blocks 16. The positioning grooves 14 are formed by the bottom surface of the base 1 being recessed upwards. When the lower end of the base 1 is inserted into the end cover 15, the positioning blocks 16 are inserted into the positioning grooves 14. In use, the lower end of the base 1 can be inserted into the end cover 15, and the positioning grooves 14 on the outside of the base 1 allow the positioning blocks 16 inside the end cover 15 to mate with the positioning grooves 14 on the base 1, thereby achieving relative fixation of the base 1 within the end cover 15, preventing movement or rotation during use. This design facilitates the connection between the base 1 and the end cover 15, and the base 1 can be raised according to actual needs to improve user comfort.
